From Portable to Mobile: An In-Depth Interpretation of the 7702 Wheeled Mobile Cleaning Station, The Scene Revolution Hidden in Details

Column：Company News Time：2025-12-02
Qingdao Chuanghui Industry’s 7702 Wheeled Mobile Cleaning Station, an upgrade of the 7701, enhances "functionality" and "flexibility" via three core structures. Its rectangular tabletop boosts space/safety; dual hollow pillars balance stability/portability; 30L tank with rollers enables mobility. It also offers custom solutions (inductive pumps, multi-capacity tanks) for outdoor, construction, and public health scenarios, redefining mobile cleaning.

In fields such as outdoor equipment, temporary infrastructure, and public health emergencies, balancing "portability" and "practicality" has always been a core proposition in product design. 


As an upgraded version of the 7701 portable cleaning station, the 7702 Wheeled Mobile Cleaning Station launched by Qingdao Chuanghui Industry is not a simple accumulation of parameters. Instead, it addresses user pain points in scenarios, achieving dual breakthroughs in "functionality" and "flexibility" in three core structures (tabletop, support pillars, and water tank), and even developing customized solutions for multiple scenarios. 


Today, we will analyze how this product redefines the value of "mobile cleaning" from three dimensions: design logic, technical details, and scenario adaptation.



I. Tabletop Upgrade: From "Functional" to "User-Friendly" – Every Modification Addresses Real Needs


While the oval tabletop of the 7701 model meets basic cleaning needs, it gradually revealed three key pain points in practical use: "insufficient space," "easy water splashing," and "room for safety improvement." The 7702’s tabletop design directly provides solutions to these issues, with every adjustment reflecting in-depth consideration of user experience.]


1.Shape & Protection: Rectangular Design + Rounded Anti-Collision Edges – Balancing Space and Safety


The core goal of changing the tabletop from oval to rectangular is to "expand effective usable area." Compared to the 7701, the 7702’s tabletop has a horizontal span increased by approximately 15% (measured data), which can simultaneously meet the light cleaning needs of two people or provide a larger operating space for one person (e.g., outdoor washing, small tool cleaning).
More importantly, the rectangular design does not compromise safety: the tabletop corners adopt rounded anti-collision treatment, with the edge radius controlled between R3-R5 (the common anti-collision radius in the industry is R2-R3). This design not only avoids collision risks caused by sharp corners but also prevents wasted tabletop space due to excessively large radii.

2. Function Retention & Optimization: Practical Design Without Compromise – Maximizing Convenience in Details


The well-received hand sanitizer pump and detachable elbow water pipe of the 7701 have been fully retained, and both are included in the parts package as standard accessories. The hand sanitizer pump requires no external power supply, making it suitable for scenarios without electricity.
The elbow water pipe can be adjusted 360 degrees, which not only prevents water from splashing by directly hitting the tabletop but also accurately targets cleaning areas (e.g., gaps in cleaning tools).

More thoughtfully, to address potential installation difficulties for users, Chuanghui Industry explicitly provides a "user manual" service. This is particularly important in non-professional installation scenarios such as outdoor areas and construction sites, as it avoids functional failure caused by improper accessory installation – essentially an extended guarantee for the "ease of use of portable products."



II. Support Pillar Upgrade: From "Single-Strut" to "Dual-Strut", Stable Innovation with Hollow Process and Traditional Inspiration


As the "skeleton" of the cleaning station, the support pillar’s stability directly determines the product’s service life and safety in use. The upgrade of the 7702’s support pillar design is not just an "increase in quantity," but a combination of material technology and structural aesthetics.


1.Dual-Strut Design: Doubling Stability Without Compromising Portability



The 7701 uses a single support pillar to hold the tabletop. Although it meets light-use needs, it tends to shake slightly in outdoor windy environments or when the tabletop bears heavy items (e.g., a bucket full of water). The 7702 is upgraded to dual support pillars, and through the "two-point support" principle, the tabletop stability is increased by approximately 60% (in actual tests, the tabletop shaking amplitude is less than 2cm in an 8-level light wind environment, far lower than the 5cm of the 7701).

However, the dual-strut design does not increase disassembly difficulty – the support pillars still adopt the 7701’s "double-ended installation structure": the top uses spiral installation, which can be locked by twisting clockwise to the fixed buckle; the bottom has a special-shaped buckle design, and the installation logic of "press the big end first, then the small end" is simple and easy to understand. A single person can complete the disassembly and assembly of the two support pillars within 1 minute, perfectly retaining the core advantage of "portability."




2. Materials & Aesthetics: Hollow Blow Molding + Bridge Arch Design – Combining Rigidity with Visual Appeal


The support pillars are made using the hollow blow molding process. While this process is not uncommon in outdoor products, the 7702’s advantage lies in its "uniform wall thickness" – it not only ensures structural rigidity (able to withstand 50kg of vertical pressure without deformation) but also controls weight, balancing "stability" and "portability."

More ingeniously, the pillars feature a "perforable tube hole" design, inspired by the "arch structure" of traditional Chinese bridge arches. On one hand, the tube holes can be used to thread water pipes, avoiding tangling; on the other hand, the arch structure itself enhances the pillars’ bending resistance, while adding a sense of design to the otherwise plain pillars, breaking the stereotype of outdoor tools being "clunky, black and crude."



III. Water Tank Upgrade: 30L Capacity + Roller Design, a Key Leap from "Portable" to "Mobile"


If the upgrades to the tabletop and support pillars are about "optimizing the experience," then the transformation of the water tank is the core of the 7702’s "defining a new product category" – upgrading the "portable cleaning station" to a "wheeled mobile cleaning station," and the key lies in the two innovations of the water tank.


1.Capacity and Versatility: 30L Endurance + M28 Metric Thread, Adaptable to Global Scenarios


The 7702’s water tank capacity is increased from the 7701’s 17L to 30L. Calculated based on an adult’s water consumption for a single handwash (about 0.5L), it can meet the basic cleaning needs of 60 people. This capacity design precisely matches "small and medium-sized temporary scenarios" (e.g., a 10-person camping team, a 20-person construction team, or a temporary medical site), avoiding the trouble of frequent water refilling.

At the same time, the water tank inlet adopts an M28 global metric thread and is equipped with a sealing cap – this detail reflects the thinking of a "globalized product": whether it is a standard water pipe in China or a common interface overseas (e.g., in Europe and Africa), it can be directly connected for water filling without additional adapter accessories. It is especially suitable for scenarios such as cross-border rescue and overseas construction sites, reducing the usage threshold caused by "interface mismatch."



2. Mobility Breakthrough: Roller Design Unlocks Full-Scenario Adaptation


The most intuitive upgrade of the 7702 is the addition of rollers at the rear of the water tank. Though this modification seems simple, it completely transforms the product’s application scenarios:
When filled with 30L of water, the 7702 weighs approximately 35kg, and a single person can push it via the rollers for flexible movement in scenarios such as campsites, construction sites, and hospital corridors.

The rollers are also made of LDPE material. Practical tests show they roll smoothly on various surfaces (including gravel, concrete, and grass) without jamming or slipping, and can even move stably on slightly sloped ground (less than 15°), making the product adaptable to complex outdoor environments.



IV. Customized Combinations: From "Single Product" to "Scenario Solutions", Covering Diverse Needs


The value of the 7702 lies not only in its own structural upgrades but also in the "multi-dimensional customized combination solutions" provided by the brand. Through combinations with different accessories, the "cleaning station" is extended into a "comprehensive hygiene solution," precisely matching the core needs of different scenarios.


1.7702 + Inductive Electric Pump: Labor-Saving Upgrade for High-Frequency Use Scenarios


When equipped with an inductive electric pump, the cleaning station is upgraded from "foot-operated water outlet" to "inductive water outlet" – no need to step on it; just extend your hand to the inductive area to get water. This not only reduces foot-to-equipment contact (more hygienic) but also reduces fatigue from frequent stepping (e.g., in high-frequency use scenarios such as hospital outpatient clinics and temporary hand-washing points in scenic areas). The electric pump uses 12V low-voltage power supply and can be used with a power bank or outdoor power source, without the need for external mains power, retaining its mobile property.



2. 7702 + Multi-Capacity Water Tanks: Customizable Endurance for Varying Crowd Densities


In addition to the standard 30L water tank, the brand also provides multi-capacity water tank options for users to choose from.



3. 7702 + Toilet: Water Recycling for Water-Scarce and Household Scenarios


       This combination is a concentrated reflection of the 7702’s "scenario-based thinking" and is divided into two solutions:

  • Matching with a portable toilet: Wastewater from handwashing can be directly used for flushing, realizing "one water for two uses." In water-scarce areas such as Africa or outdoor camping scenarios (without external water sources), this can significantly reduce water consumption (with a measured water saving of 40%) while reducing wastewater discharge, meeting environmental protection needs.



  • Matching with an integrated toilet: The toilet and cleaning station adopt an integrated design, featuring a neater appearance and easier installation. It is suitable for scenarios with high hygiene standards such as hospital wards, temporary isolation points, and public places, avoiding space waste and inconvenience caused by "separation of cleaning station and toilet."


V. The Upgrade Logic of Qingdao Chuanghui Industry’s 7702 Wheeled Mobile Cleaning Station: A "User-Centered" Product Philosophy


From the 7701 to the 7702, Qingdao Chuanghui Industry’s upgrade path is not a "parameter competition" but "scenario-driven": the tabletop’s anti-splashing and anti-collision features solve safety and cleanliness pain points in outdoor use; the support pillars’ dual-strut and hollow process balance the needs of stability and portability; the water tank’s rollers and metric thread break regional and scenario limitations; and the multi-dimensional customized combinations upgrade the product from a "single tool" to a "solution."

For outdoor enthusiasts, construction site managers, and public health practitioners, the value of the 7702 Wheeled Mobile Cleaning Station lies not only in "being able to clean" but also in "being able to clean conveniently, safely, and efficiently anywhere." This may be the core competitiveness of an excellent outdoor equipment: solving real pain points in details and covering more scenarios through upgrades.
