[0002] The drawer-type shoe washing machine is a specially designed shoe washing device, and its main feature is that its structure is similar to a drawer, which is convenient for users to put shoes in and take out. Compared with traditional shoe washing machines, the drawer-type shoe washing machine has a more compact and convenient structure and higher cleaning efficiency, and is increasingly favored by users.
[0003] At present, the existing drawer-type shoe washing machines mainly consist of two major parts, including a drawer and a box body. The drawer can be opened and closed inside the box body. A cleaning bucket is installed in the drawer, and the cleaning bucket is connected with a water inlet pipe and a drain pipe. After the shoes are washed once, the sewage in the cleaning bucket is discharged through the drain pipe by a water pump. Then, after one drainage, due to the backflow of residual water, air will accumulate in the drain pipe at the upstream end and the downstream end of the water pump. Therefore, during the next drainage, it is easy to cause the problem of air entrapment in the drainage of the water pump, resulting in a significant reduction in the working efficiency of the drainage pump, thereby causing poor drainage or slow drainage speed, affecting the normal operation of the equipment and the user experience.
[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Utility Model
[0005] The utility model aims to solve the above technical problems, that is, to solve the problems that the existing drawer-type shoe washing machine is prone to air entrapment in drainage, resulting in a reduction in the working efficiency of the drainage pump, and causing poor drainage or slow drainage speed.
[0006] In a first aspect, the utility model provides a waterway structure of a shoe washing device. The shoe washing device includes a box body, a drawer and a cleaning bucket. The drawer is slidably embedded inside the box body, the cleaning bucket is installed in the drawer, the cleaning bucket has a drainage port, and the waterway structure includes a first drain pipe, a second drain pipe and a pumping mechanism. The first end of the first drain pipe is connected to the drainage port, the second end of the first drain pipe is connected to the water inlet of the pumping mechanism, the first end of the second drain pipe is connected to the water outlet of the pumping mechanism, the second end of the second drain pipe communicates with the outside of the box body, the first drain pipe is gradually inclined downward from its first end to the second end, and the sewage in the cleaning bucket can flow through the first drain pipe, the pumping mechanism and the second drain pipe in sequence and then be discharged to the outside of the box body.

The second end of the second drain pipe is connected to the water inlet of the drain box, the first end of the external drain pipe is connected to the water outlet of the drain box, and the second end of the external drain pipe communicates with the outside of the box body.
[0011] In the preferred technical solution of the above waterway structure, the first end of the external drain pipe is lower than the second end of the external drain pipe.
[0012] In the preferred technical solution of the above waterway structure, a plurality of card slots are provided on the inner side of the box body, and the second drain pipe is clamped in the card slots.
[0013] In the preferred technical solution of the above waterway structure, the first drain pipe is made of a flexible material.
[0014] In the preferred technical solution of the above waterway structure, the pumping mechanism is a drain pump.
[0015] In a second aspect, the present utility model further provides a shoe washing device, which includes the above waterway structure, and the waterway structure is arranged between the drawer and the box body.
[0016] Those skilled in the art can understand that the technical solution of the present utility model provides a water circuit structure for a shoe washing device. The shoe washing device includes a box body, a drawer, and a cleaning bucket. The drawer is slidably embedded inside the box body, and the cleaning bucket is installed in the drawer. The cleaning bucket has a drain port. The water circuit structure includes a first drain pipe, a second drain pipe, and a pumping mechanism. The first end of the first drain pipe is connected to the drain port, the second end of the first drain pipe is connected to the water inlet of the pumping mechanism, the first end of the second drain pipe is connected to the water outlet of the pumping mechanism, and the second end of the second drain pipe communicates with the outside of the box body. The first drain pipe is gradually inclined downward from its first end to its second end. The sewage in the cleaning bucket can flow through the first drain pipe, the pumping mechanism, and the second drain pipe in sequence and then be discharged to the outside of the box body. In the case of adopting the above technical solution, the present utility model can avoid the reduction of the working efficiency of the pumping mechanism caused by air entrapment during drainage of the shoe washing device, resulting in poor drainage or slow drainage speed. Specifically, the first drain pipe is gradually inclined downward from the end connected to the drain port of the cleaning bucket to the end of the water inlet of the pumping mechanism, so that the sewage in the cleaning bucket can smoothly flow into the pumping mechanism, reducing the drainage resistance and the possibility of air being sucked into the pumping mechanism, effectively preventing the problem of air entrapment during drainage caused by air retention, and improving the drainage efficiency. In addition, it can also avoid the sewage backflow or accumulation in the cleaning bucket caused by poor drainage, ensuring the continuity and effectiveness of the cleaning process.
[0017] Further, the second drain pipe of the present utility model is fixed to the inner side of the box body in an inverted U shape. Through this setting, after the first drainage of the shoe washing device, a part of the water in the second drain pipe flows to the pumping mechanism through its first end, and the other part flows to the outside of the box body through its second end, so as to effectively prevent air from entering the pumping mechanism through the second drain pipe and causing air entrapment problems in the pumping mechanism, ensuring that the pumping mechanism can work normally when the shoe washing device drains water again.
[0018] Furthermore, a filtering member is provided at the first end of the first drain pipe of the present utility model. Through this setting, the filtering component can remove impurities and particulate matters in the sewage, improve the water quality, reduce the damage to the pumping mechanism, thereby reducing the blockage and wear of the pumping mechanism, and preventing the problem of poor drainage or slow drainage speed caused by the blockage of the pumping mechanism.
[0019] Furthermore, the waterway structure of the present utility model further includes a drainage box and an external drainage pipe. The second end of the second drainage pipe is connected to the water inlet of the drainage box, the first end of the external drainage pipe is connected to the water outlet of the drainage box, and the second end of the external drainage pipe communicates with the outside of the box body. The drainage box can prevent external sewage or gas from flowing back into the pumping mechanism through the external drainage pipe, thereby playing a role in isolating air, further preventing air from entering the pumping mechanism and causing the problem of air entrapment in the pumping mechanism. In addition, the drainage box can also serve as a buffer area, which can slow down the water flow speed, reduce the impact on the pipeline and the pumping mechanism caused by too fast water flow, and help extend the service life of the shoe washing equipment and reduce the maintenance cost.
[0020] Furthermore, the first end of the external drainage pipe of the present utility model is lower than the second end of the external drainage pipe. Through this setting, the water flow can flow more smoothly along the external drainage pipe, reducing the accumulation and backflow of water caused by the obstruction of the water flow. In addition, it also helps to reduce the deposition of dirt and impurities in the external drainage pipe, thereby reducing the risk of blockage of the external drainage pipe.

[0032] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model. For example, although the following embodiments are introduced in combination with a drawer-type shoe washing machine, the waterway structure provided by the present utility model is also applicable to other products that need to solve the problem of air entrapment during drainage.
[0033] It should be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "arranged" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0034] Based on the problem pointed out in the background technology that the existing drawer-type shoe washing machine is prone to air entrapment during drainage, resulting in a reduction in the working efficiency of the drainage pump, leading to poor drainage or slow drainage speed. The present utility model provides a waterway structure of a shoe washing device and a shoe washing device, aiming to effectively solve the problem of air entrapment during drainage of the drawer-type shoe washing machine by gradually inclining the first drainage port between the drainage port of the cleaning bucket and the pumping mechanism downward from the end connected to the drainage port of the cleaning bucket to the end of the water inlet of the pumping mechanism.
[0035] First, refer to Figure 1 and Figure 2 , where Figure 1 is an isometric view of the shoe washing device of the present utility model, and Figure 2 is a top view of the shoe washing device of the present utility model.
[0036] In the first aspect, the present utility model provides a waterway structure of a shoe washing device. The shoe washing device includes a box body 1, a drawer 2, and a cleaning bucket 3. The drawer 2 is slidably embedded inside the box body 1, and the cleaning bucket 3 is installed in the drawer 2. The cleaning bucket 3 has a drainage port 31. The waterway structure includes a first drain pipe 41, a second drain pipe 42, and a pumping mechanism 43. The first end of the first drain pipe 41 is connected to the drainage port 31, the second end of the first drain pipe 41 is connected to the water inlet of the pumping mechanism 43, the first end of the second drain pipe 42 is connected to the water outlet of the pumping mechanism 43, and the second end of the second drain pipe 42 is communicated with the outside of the box body 1. The first drain pipe 41 is gradually inclined downward from its first end to its second end, and the sewage in the cleaning bucket 3 can flow through the first drain pipe 41, the pumping mechanism 43, and the second drain pipe 42 in sequence and then be discharged to the outside of the box body 1.
[0037] The first drain pipe 41 serves as the preliminary channel for sewage discharge. Its function is to guide the sewage in the cleaning bucket 3 to the pumping mechanism 43. The pumping mechanism 43 is arranged between the first drain pipe 41 and the second drain pipe 42. Its function is to pressurize the sewage conveyed by the first drain pipe 41 and then discharge it to the second drain pipe 42. The second drain pipe 42 safely and efficiently discharges the sewage pressurized by the pumping mechanism 43 outside the box body 1 of the shoe-washing device. The first drain pipe 41 gradually slopes downward from the end connected to the drain outlet 31 of the cleaning bucket 3 to the end of the water inlet of the pumping mechanism 43, so that the position of the pumping mechanism 43 is at the lowest point of the waterway structure. Thus, the sewage in the cleaning bucket 3 can smoothly flow into the pumping mechanism 43, reducing the drainage resistance and the possibility of air being sucked into the pumping mechanism 43, effectively preventing the problem of drainage air entrapment caused by air retention, and improving the drainage efficiency. In addition, it can also avoid the sewage backflow or accumulation in the cleaning bucket 3 caused by poor drainage, ensuring the continuity and effectiveness of the cleaning process.
[0038] Preferably, the pumping mechanism 43 of the present utility model is a drainage pump. The sewage in the cleaning bucket 3 is discharged outside the box body 1 through the pumping action of the drainage pump. Further, the drainage pump of the present utility model is a semi-open impeller centrifugal pump or an open impeller centrifugal pump, so as to have a certain anti-blocking ability and prevent the particles in the shoes from causing blockage of the drainage pump. Furthermore, in other embodiments, the drainage pump can also be a single-suction centrifugal pump, a double-suction centrifugal pump, etc. The present utility model does not specifically limit the type of the drainage pump, as long as it can ensure the high-efficiency discharge of sewage.
[0039] Preferably, as Figure 3 and Figure 4 shown, the second drain pipe 42 is fixed to the inner side of the box body 1 in an inverted U shape.
[0040] By fixing the second drain pipe 42 to the inner side of the box body 1 in an inverted U shape, after the first drainage of the shoe-washing device, a part of the water in the second drain pipe 42 flows to the pumping mechanism 43 through its first end, and another part flows to the outside of the box body 1 through its second end. Thus, a water seal can be formed inside the second drain pipe 42, effectively preventing the gas from flowing back to the pumping mechanism 43 through the second drain pipe 42, and effectively preventing the air from entering the pumping mechanism 43 through the second drain pipe 42 and causing the problem of air entrapment in the pumping mechanism 43, so as to ensure that the pumping mechanism 43 can work normally when the drawer-type shoe-washing machine drains water again.
[0041] Preferably, a plurality of card slots are arranged on the inner side of the box body 1, and the second drain pipe 42 is clamped in the card slots.
[0042] By designing the second drain pipe 42 in a form that can be snapped into the card slot, the entire water conservancy structure becomes more modular. The second drain pipe 42 can be independently replaced or upgraded without the need for large-scale disassembly or reconstruction of the entire box body 1, improving the flexibility and scalability of the product. In addition, the design of the card slot simplifies the installation process of the second drain pipe 42. The installer only needs to align the drain pipe with the card slot and gently push it in to complete the installation, without the need to use additional fixing tools or complex installation steps. This not only improves the installation efficiency but also reduces the possibility of errors during the installation process.
[0043] Preferably, as Figure 3 and Figure 4 shown, a filtering member 5 is provided at the first end of the first drain pipe 41.
[0044] After the sewage is discharged from the drain outlet 31, it flows into the first drain pipe 41 after being filtered by the filtering member 5. Therefore, the filtering member 5 can remove impurities and particulate matters in the sewage and improve the water quality. Through the filtering action of the filtering member 5 of the present utility model, the damage to the pumping mechanism 43 caused by impurities in the sewage can be reduced, and the risks of blockage and wear of the pumping mechanism 43 can be lowered, thereby preventing the problem of poor drainage or slow drainage speed caused by blockage of the pumping mechanism 43.
[0045] Preferably, the filtering member 5 is a drain filter.
[0046] The working principle of the drain filter is based on physical filtration and gravity. When the sewage in the cleaning bucket 3 passes through the filter, the impurities therein are intercepted by the filter mesh frame and collected in the filter cylinder. As the impurities accumulate, the liquid level inside the filter gradually rises. When the liquid level reaches the set drainage condition, the automatic drain valve automatically opens to discharge the accumulated liquid outside the filter. At the same time, the filtered clean liquid or gas continues to flow out through the filter, thereby effectively intercepting and collecting various impurities in the cleaning bucket 3 and improving the filtration efficiency. In addition, in other embodiments, the filtering member 5 can also be other types of filtering members 5 such as a screen filter or a particle filter. The present utility model does not limit the specific type of the filtering member 5 as long as it can effectively intercept impurities and particles in the sewage.
[0047] Preferably, as Figure 3 and Figure 4 shown, the waterway structure further includes a drain box 44 and an external drain pipe 45. The second end of the second drain pipe 42 is connected to the water inlet of the drain box 44, the first end of the external drain pipe 45 is connected to the water outlet of the drain box 44, and the second end of the external drain pipe 45 communicates with the outside of the box body 1.
[0048] The drainage box 44 serves as a transfer station and is located between the second drain pipe 42 and the external drain pipe 45. Its main function is to collect the sewage flowing in from the second drain pipe 42 and temporarily store this sewage until it is discharged outside the box body 1 by the external drain pipe 45; the first end of the external drain pipe 45 is connected to the water outlet of the drainage box 44, and the second end of the external drain pipe 45 is communicated with the outside of the box body 1. Its function is to discharge the sewage stored in the drainage box 44 outside the box body 1 to ensure the cleanliness and dryness inside the drawer - type shoe washing machine. In addition, the drainage box 44 can prevent external sewage or gas from flowing back into the pumping mechanism 43 through the external drain pipe 45, thus playing a role in isolating air and further preventing air from entering the pumping mechanism 43 and causing the problem of air entrapment in the pumping mechanism 43. Further, the drainage box 44 can also serve as a buffer area, which can slow down the water flow speed, reduce the impact on the pipeline and the pumping mechanism 43 caused by too fast water flow, contribute to extending the service life of the drawer - type shoe washing machine and reducing the maintenance cost.
[0049] Preferably, as Figure 3 and Figure 4 shown, the first end of the external drain pipe 45 is lower than the second end of the external drain pipe 45.
[0050] With this setting, the water flow can flow more smoothly along the external drain pipe 45, reducing the phenomena of water accumulation and backflow caused by water flow obstruction, and also helping to reduce the deposition of dirt and impurities in the external drain pipe 45, thereby reducing the risk of blockage of the external drain pipe 45. In addition, during the drainage process, the air pressure inside the external drain pipe 45 will change. The design that the first end of the external drain pipe 45 is lower than the second end helps to maintain the air pressure balance inside and outside the external drain pipe 45, preventing problems such as rupture or leakage of the external drain pipe 45 caused by too large a pressure difference.
[0051] Preferably, the first drain pipe 41 is made of flexible material.
[0052] Since the drawer - type shoe washing machine needs to pull out the drawer 2 during use, during the process of pulling out the drawer 2, the first drain pipe 41 has to move along with the drawer 2. Therefore, in this utility model, the first drain pipe 41 is set to be made of flexible material, and they can be bent, twisted or stretched, so that they will not break during the process of following the movement of the drawer 2, ensuring the normal discharge of sewage in the cleaning bucket 3.
[0053] Exemplarily, the first drain pipe 41 is made of rubber material. Rubber has the advantages of high toughness, high elasticity, wear resistance and corrosion resistance. Selecting rubber material as the material of the first drain pipe 41 can ensure that the first drain pipe 41 will not break under the action of repeated bending, twisting or stretching, and can ensure the smoothness of drainage. In addition, since the processing technology of rubber is very mature, the source of rubber is rich, and the physical and chemical properties of rubber are also very stable, which is suitable for use in a humid environment such as a shoe washing machine. Therefore, using rubber as the material of the first drain pipe 41 can not only reduce the production cost of parts, but also extend the service life of parts. Of course, in other embodiments, the first drain pipe 41 can also be made of polymer materials such as PVC (polyvinyl chloride) and PE (polyethylene). The present utility model does not specifically limit the specific flexible material of the first drain pipe 41, as long as it can ensure that the first drain pipe 41 will not break under the action of repeated bending, twisting or stretching.
[0054] In addition, the present utility model also provides a shoe washing device, and the shoe washing device includes the above-mentioned water path structure, and the water path structure is arranged between the drawer 2 and the box body 1.
[0055] So far, the technical solution of the present utility model has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present utility model.
