Description

Technical Field

[0001] This utility model relates to the field of environmental sanitation technology, and in particular to a mobile washroom device. Background Technology

[0002] A washroom is a room equipped with washing and toilet facilities. In modern society, with the diversification of people's lifestyles and the expansion of their activity range, the demand for flexibility in sanitary facilities is increasing. As a result, mobile washroom devices have emerged. These are washroom facilities that can be moved freely. Their emergence has broken the limitation that traditional washrooms must rely on fixed buildings and has played a key role in many temporary or highly mobile scenarios.

[0003] Portable washroom units typically consist of an outer shell (made of metal or composite materials), internal facilities (washbasin, toilet, water tank, faucet, etc.), and a towing device. When water is supplied, water flows from the faucet under water pressure using an external water source or an internal water tank, while the toilet is flushed by gravity or pressure from the water tank. When draining, wastewater is collected through pipes and temporarily stored in a wastewater tank, which is cleaned regularly and can be moved to different locations as needed.

[0004] Currently, while traditional mobile washroom units play an important role, they also have shortcomings. On the one hand, they are inefficient in terms of water resource utilization. Due to the lack of sufficient consideration of water recycling paths in the design, water used for handwashing is discharged directly into the sewage tank in the conventional manner because there is no dedicated recycling and filtration system. It cannot be reused inside the unit, resulting in a waste of water resources. On the other hand, cleaning and replacing the septic tank is difficult and unsanitary. Due to the unreasonable structural design and the complicated connection method with the overall unit, there is a lack of convenient disassembly and replacement mechanisms, which can easily lead to sewage leakage and fecal spillage during operation, resulting in environmental pollution. Therefore, mobile washroom units are proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a mobile washroom device, which aims to improve the problems of low water resource utilization and inconvenient, time-consuming and labor-intensive sewage treatment in the existing traditional mobile washroom devices.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 An embodiment of this utility model provides a mobile washroom device, including a base 1, a box 2 mounted on the top of the base 1, a toilet 4 and a washbasin 7 mounted inside the box 2, a faucet 5 mounted on the top of the washbasin 7, a water tank 3 mounted on the top of the toilet 4, a box door 8 mounted on the outside of the box 2, a feces tank 16 and a collection tank 10 mounted on the side of the base 1 away from the box door 8, a filter assembly 9 mounted in the middle of the base 1, and a disassembly assembly 17 mounted on the side of the feces tank 16 away from the collection tank 10.

[0034] The filter assembly 9 includes a water pump 11, which is located in the middle of the collection tank 10. A delivery pipe 12 is fixedly connected to the output end of the water pump 11. A faucet 5 is fixedly connected to the end of the delivery pipe 12 furthest from the water pump 11. A delivery pipe 13 is fixedly connected between the delivery pipe 12 and the water tank 3. A valve 14 is installed in the middle of the delivery pipe 13. A sensor 6 is installed in the middle of the faucet 5. A filter screen 15 is installed in the middle of the collection tank 10. A washbasin 7 is located directly above the filter screen 15. After the user completes the handwashing process in the washbasin 7, the wastewater flows down the drain of the washbasin 7 into the collection tank 10 below it under the pull of gravity. The filter screen 15 inside the collection tank 10 quickly starts the filtration process, effectively intercepting impurities such as hair, larger dust particles, and some residual hand soap foam, completing the initial purification of the wastewater. The water after this initial filtration... Driven by a powerful water pump 11 located at the center of the collection tank 10, the water flows along the first delivery pipe 12. One branch of the water flow is directed directly to the faucet 5. When the sensor 6 equipped with the faucet 5 detects the user's hand approaching, waving, or placing, the faucet 5 responds immediately, releasing recycled water to meet the user's need for washing hands again. The other water flow proceeds orderly along the second delivery pipe 13, which is firmly connected to the first delivery pipe 12 and the second water tank 3. During this process, the valve 14 installed in the middle of the second delivery pipe 13 plays a key regulatory role. It can control the size and on / off state of the water flow with high precision according to actual needs, thereby achieving reasonable allocation and precise control of the water storage in the second water tank 3, providing a stable and appropriate flushing water source for the toilet 4, and ensuring that the efficient flushing function of the toilet 4 can be realized smoothly.

[0035] This approach significantly improves the recycling rate of water resources and reduces unnecessary waste of water resources. When dealing with temporary or highly mobile usage scenarios, it significantly reduces the dependence on external water sources, effectively saves water acquisition costs and alleviates supply pressure. At the same time, this scientific and reasonable design makes the internal water resource allocation of the device more intelligent and balanced, which not only improves the stability and reliability of water use in each component, but also extends the service life of the device as a whole and reduces the risk of failure caused by poor water resource management.

[0036] Reference Figure 2 and Figure 4 The disassembly assembly 17 includes a pull rod 18, which is slidably connected to the middle of the base 1. A limiting piece 20 is fixedly connected to the outer side of the pull rod 18. A hole 19 is provided on the side of the septic tank 16 near the pull rod 18, and the pull rod 18 is slidably connected to the middle of the hole 19. A spring 21 is provided inside the base 1, and the spring 21 abuts against the base 1 and the limiting piece 20. An auxiliary ladder 22 is installed on the side of the base 1 away from the water pump 11. A traction block 23 is fixedly connected to the outer side of the housing 2 to facilitate the traction and movement of the device by external power. When the septic tank 16 needs to be cleaned, the user manually pulls the pull rod 18. The pull rod 18 begins to slide smoothly in a straight line within the sliding track structure built inside the base 1. During the sliding process, the limiting piece 20 fixed to the outer side of the pull rod 18 moves synchronously and controls the movement of the lower part of the tank. The spring 21 applies pressure, causing it to gradually contract and store elastic potential energy. As the pull rod 18 continues to slide, its end eventually comes out smoothly from the pre-set hole 19 on one side of the septic tank 16. This process completely releases the original tight connection between the septic tank 16 and the base 1, allowing the septic tank 16 to be easily and conveniently removed from the entire device for subsequent comprehensive cleaning or direct replacement with a new septic tank. When the cleaning is completed, the previously compressed spring 21 begins to relax under its own elastic restoring force, pushing the limiting plate 20 and the pull rod 18 connected to it to move in the opposite direction along the original sliding path until the pull rod 18 returns to its initial position, restoring it to a state where it can be reconnected and installed with the septic tank 16, greatly facilitating the next installation of the septic tank 16.

[0037] This method of cleaning and replacing septic tanks reduces the complexity and difficulty of operation, allowing ordinary users to complete the relevant operations without the need for professional tools or special training. At the same time, the convenient disassembly and installation mechanism improves the maintenance efficiency of the entire mobile washroom unit, reduces downtime caused by inconvenient septic tank cleaning, and ensures that the mobile washroom unit can operate continuously and stably, meeting people's needs in various temporary or mobile scenarios.

[0038] Working principle: First, during use, when the user washes their hands in the washbasin 7, the water flows through the washbasin 7 into the collection pool 10 below. The filter screen 15 in the collection pool 10 will initially filter the impurities in the water. The filtered water is then transported through the first delivery pipe 12 by the water pump 11. Part of the water is directly supplied to the faucet 5 for further hand washing. When the sensor 6 detects the user's hand movement, the faucet 5 dispenses water, and the other part of the water is transported through the second delivery pipe 13 to the second water tank 3 to provide water for flushing the toilet 4. The valve 14 can control the flow of water through the second delivery pipe 13, thereby reasonably regulating the water storage in the second water tank 3.

[0039] Secondly, when it is necessary to clean the septic tank 16, pull the lever 18. The lever 18 slides in the base 1 and drives the limiting plate 20 to compress the spring 21. The lever 18 disengages from the hole 19 on one side of the septic tank 16, thereby disconnecting the septic tank 16 from the base 1. This allows the septic tank 16 to be easily disassembled for cleaning or replacement. After cleaning, the lever 18 can be reset under the elastic force of the spring 21, making it convenient to install the septic tank 16 next time.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
