Detailed Implementation

[0041] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0042] According to relevant technologies, a sterilization module is installed in the water tank of a water purification device to sterilize the water in the tank regularly to prevent bacteria from growing in the water and affecting drinking. However, the sterilization module has an effective sterilization range and cannot achieve sterilization without dead corners.

[0043] Therefore, this utility model provides a water tank assembly 100, which can improve the sterilization effect of the sterilization module 30 on the water flow in the water tank 10, and prevent bacteria from growing in the water tank 10, thus affecting drinking; and it is also provided with a diagonally arranged water outlet 13 and return outlet 14 to further improve the sterilization effect of the sterilization module 30.

[0044] like Figures 1 to 5 According to the embodiment of the present utility model, the water tank assembly 100 includes a water tank 10, a drive component 20, and a sterilization module 30.

[0045] A sterilization module 30 can be installed inside the water tank 10. The sterilization module 30 can sterilize and disinfect the water in the water tank 10 to prevent the growth of bacteria in the water. However, the sterilization range of the sterilization module 30 is limited, and there are sterilization dead zones in the water tank 10. Therefore, the water tank 10 can also have an outlet 13 and a return port 14. The drive unit 20 connects the outlet 13 and the return port 14 and is configured to drive the water flow from the outlet 13 to the return port 14. The drive unit 20 drives the water flow to circulate between the drive unit 20 and the water tank 10, so that the water that is stagnant in the dead zone can flow under the action of the drive unit 20 and flow into the area that can be sterilized by the sterilization module 30, thereby achieving sterilization of the water flow.

[0046] Furthermore, the outlet 13 is located at the bottom of the water tank 10, and the return port 14 is located at the top of the water tank 10. Under the action of the driving component 20, the water in the water tank 10 flows through the outlet 13 to the driving component 20, and after flowing through the driving component 20, it flows back to the water tank 10 through the return port 14. At this time, the outlet 13 can be located at the bottom of the water tank 10, and the return port 14 can be located at the top of the water tank 10. In this way, the outlet 13 and the return port 14 can be set diagonally along the top and bottom of the water tank, maximizing the distance between the water inlet and outlet, and making the disturbance more sufficient, so that the sterilization module 30 can fully sterilize and disinfect the water.

[0047] Furthermore, the outlet 13 and the return port 14 are located on opposite sides of the water tank 10 along the width direction. With this arrangement, the outlet 13 and the return port 14 can be arranged opposite each other in the width and height directions. This allows the outlet 13 and the return port 14 to be set diagonally opposite each other in the water tank, maximizing the distance between the water inlet and outlet and making the disturbance more sufficient, so that the sterilization module 30 can fully sterilize and disinfect the water flow.

[0048] Therefore, according to the water tank assembly 100 of this utility model embodiment, the water flow is driven by the driving component 20 to circulate between the water tank 10 and the driving component 20, so that the sterilization module 30 can thoroughly disinfect the water flow in the water tank 10, improve the sterilization effect of the sterilization module 30, and prevent bacteria from growing in the water tank 10, which would affect drinking. In addition, it is provided with a diagonally arranged water outlet 13 and a return port 14, which can be arranged diagonally along the water tank to maximize the distance between the water inlet and outlet, and make the disturbance more sufficient, so that the sterilization module 30 can fully sterilize and disinfect the water flow.

[0049] like Figure 4In some embodiments of this utility model, the water tank assembly 100 further includes a flow guiding component 40, which is disposed inside the water tank 10. The water tank 10 also has a water inlet 15, which is disposed on the same side of the water tank 10 along the width direction. The water inlet 15 is connected to the drive component 20, and the interior of the flow guiding component 40 is connected to the return port 14 and the water inlet 15. In this way, the arrangement of the drive component 20 can be facilitated and the space utilization rate can be improved.

[0050] Specifically, when the water tank assembly 100 is working, under the action of the drive component 20, water flows out of the water tank 10 and flows through the outlet 13, drive component 20, inlet 15, guide component 40 and return port 14 in sequence, and finally flows back to the water tank 10, so that the sterilization module 30 can disinfect the water flow.

[0051] In addition, the inlet 15 and the outlet 13 are located on the same side of the water tank 10. In this way, the drive unit 20 can also be located on the same side of the water tank 10 and connected to the inlet 15 and the outlet 13, which can save the external space of the water tank 10 and improve the space utilization rate.

[0052] In some specific examples, the flow guiding component 40 is set as a pipeline, one end of which is connected to the return port 14 and the other end is connected to the inlet 15; in other specific examples, the flow guiding component is set as a flow channel integrated plate, which has a first flow channel, one end of which is connected to the return port 14 and the other end is connected to the inlet 15.

[0053] like Figures 1 to 5 In some embodiments of this utility model, the water tank 10 includes a tank body 11 and a tank cover 12. The top of the tank body 11 is open, and the tank cover 12 is placed on the top of the tank body 11. The flow guiding component 40 is placed on the tank cover 12 and extends along the periphery of the tank cover 12. In this way, interference between the flow guiding component 40 and the structural components inside the water tank 10 can be avoided, ensuring the normal operation of the water tank assembly 100.

[0054] It is understandable that the water tank assembly 100 contains other structural components such as a sterilization module 30 and a liquid level sensor 50. In order to avoid interference between the flow guiding component 40 and the structural components inside the water tank 10, the flow guiding component 40 can be extended along the periphery of the tank cover 12 and positioned relatively close to the peripheral wall of the water tank 10. This maximizes the distance between the water flow outlet 13 and the return outlet 14, improves the sterilization effect, and avoids structural collision between the flow guiding component 40 and the structural components, thereby improving the operational stability of the water tank assembly 100.

[0055] In some specific examples, the outlet 13 is located at the bottom of the tank 11, and the return port 14 and the inlet 15 are located on the tank cover 12.

[0056] like Figure 4In some embodiments of this utility model, the flow guiding component 40 includes a first pipe body 41 and a second pipe body 42. The first pipe body 41 extends along the width direction, and the second pipe body 42 extends along the length direction of the water tank 10. One end of the first pipe body 41 is connected to the water inlet 15, and one end of the second pipe body 42 is connected to the first pipe body 41, and the other end is connected to the return port 14. In this way, the flow guiding component 40 can be processed easily and the manufacturing cost can be reduced.

[0057] For example, the flow guiding component 40 can be injection molded. During manufacturing, the first tube 41 can extend along the width direction, and the second tube 42 can extend along the length direction. The second tube 42 can be connected to the first tube 41. After the first tube 41 is formed, the mold used for forming the first tube 41 can be demolded along the width direction. After the second tube 42 is formed, the mold used for forming the second tube 42 can be demolded along the length direction. Thus, interfaces can be left at both ends of the first tube 41, and one end of the second tube 42 is connected to the first tube 41, with an interface left at the other end. Subsequently, a plug can be used to block one of the interfaces of the first tube 41, and the other interface can be set as a return port 14 for connection with the drive component 20. The interface of the second tube 42 can be set as a return port 14 for water to flow back into the water tank 10. This facilitates the processing of the flow guiding component 40 and reduces manufacturing costs.

[0058] like Figure 4 In some embodiments of this utility model, in the length direction, the first tube 41 is closer to the peripheral wall of the water tank 10 relative to the center of the water tank 10. It can be understood that the water tank 10 may be provided with structural components such as a sterilization module 30 and a liquid level sensor 50. In order to avoid mutual interference between the first tube 41 and the structural components, the first tube 41 can be made closer to the peripheral wall of the water tank 10 relative to the center of the water tank 10 in the length direction.

[0059] like Figure 4 In some embodiments of this utility model, in the width direction, the second tube 42 is closer to the peripheral wall of the water tank 10 relative to the center of the water tank 10. It can be understood that the water tank 10 may be provided with structural components such as a sterilization module 30 and a liquid level sensor 50. In order to avoid mutual interference between the second tube 42 and the structural components, the second tube 42 can be made closer to the peripheral wall of the water tank 10 relative to the center of the water tank 10 in the width direction.

[0060] In practice, the water tank 10 can be shaped as a cuboid. Thus, in conjunction with the above, the first pipe 41 can be positioned near the width edge of the tank cover 12, and the second pipe 42 can be positioned near the length edge of the tank cover 12, in order to avoid mutual interference between the flow guiding component 40 and the structural component.

[0061] It should also be explained that if the water tank 10 is a cuboid, the center is the geometric center of the cuboid; if the water tank 10 is a cube, the center is the geometric center of the cube; and if the water tank 10 is a sphere, the center is the center of the sphere.

[0062] like Figure 2 In some embodiments of this utility model, the drive component 20 is connected to at least one of the inlet 15 and the outlet 13 via a flexible pipeline; this facilitates the spatial arrangement of the drive component 20 and improves the space utilization of the water purification equipment 1000.

[0063] For example, the water tank assembly 100 also includes a first flexible tube 70 and a second flexible tube 80. The first flexible tube 70 is connected to the drive component 20 and the water inlet 15, respectively, and the second flexible tube 80 is connected to the drive component 20 and the water outlet 13, respectively. In this way, the installation position of the drive component 20 can be more flexible, and the installation position of the drive component 20 can be adjusted according to the spatial arrangement within the water purification equipment 1000, thereby improving the space utilization rate.

[0064] The drive component 20 can be configured as a water pump.

[0065] like Figure 3 In some embodiments of this utility model, the sterilization module 30 is located on the central axis of the water tank 10. It can be understood that in order to improve the sterilization effect of the sterilization module on the water tank 10, the sterilization module 30 can be located on the central axis of the water tank. This makes it easier for the sterilization module to evenly sterilize the water flow inside the water tank and improve the sterilization effect on the water flow.

[0066] In some specific examples, the sterilization module 30 is set as an ultraviolet sterilization lamp. The irradiation range of the ultraviolet sterilization lamp is limited and cannot effectively disinfect the water flow. Therefore, the ultraviolet sterilization lamp can be set on the central axis of the water tank 10 to improve the sterilization effect. In addition, combined with the driving component 20 driving the water flow to circulate between the outlet 13 and the return port 14, the sterilization effect of the ultraviolet sterilization lamp can be greatly improved, avoiding the problem of poor sterilization caused by the ultraviolet sterilization lamp having dead spots.

[0067] It needs to be explained that, with the appendix Figures 2 to 5 For example, the ultraviolet germicidal lamps are arranged along the height direction; in the projection along the height direction, the water tank 10 is rectangular in shape, and the rectangle has a geometric center. Therefore, the axis extending along the height direction and passing through this geometric center of the water tank 10 can be understood as the central axis of the water tank 10. Of course, by changing the arrangement direction of the ultraviolet germicidal lamps and setting them on the central axis in the corresponding direction, the technical solution of this embodiment can be achieved, and it falls within the protection scope of this utility model.

[0068] like Figures 3 to 5In some embodiments of this utility model, the sterilization module 30 is set as an ultraviolet sterilization lamp, and the water tank assembly 100 also includes a liquid level sensor 50 and a protective cover 60. The liquid level sensor 50 is located inside the water tank 10, and the cover 60 is used to block the ultraviolet rays of the ultraviolet sterilization lamp from directly shining on the liquid level sensor. In this way, the liquid level sensor 50 can detect the liquid level in the water tank 10, which is convenient for timely replenishment of drinking water, and the protective cover 60 can be used to protect the liquid level sensor 50 and prevent the liquid level sensor 50 from aging.

[0069] It is understandable that a liquid level sensor 50 can be installed inside the water tank 10. The liquid level sensor 50 can be used to detect the water level inside the water tank 10. When the liquid level inside the water tank 10 is lower than a preset value, the water source can replenish drinking water into the water tank 10. In addition, the liquid level sensor 50 can be installed on the tank cover 12 of the water tank 10. By opening and closing the tank cover 12, the liquid level sensor 50 can be placed and removed inside the tank 11, improving convenience and integration.

[0070] Furthermore, in conjunction with the foregoing, the sterilization module 30 is equipped with an ultraviolet (UV) germicidal lamp. The UV germicidal lamp disinfects the water flow by releasing UV rays into the water tank 10. However, UV rays can cause photochemical reactions in the material of the level sensor 50, leading to aging and failure of the level sensor 50. Therefore, a protective cover 60 can be provided. The protective cover 60 can be fitted over the outside of the level sensor 50 to prevent direct UV radiation, thus extending the service life of the level sensor 50 and reducing the maintenance cost of the water tank assembly 100. Alternatively, the protective cover 60 can also be installed on the tank cover 12 of the water tank 10. By opening and closing the tank cover 12, the protective cover 60 can be placed and removed from the tank body 11, improving convenience and integration.

[0071] like Figure 5 In some embodiments of this utility model, the inner top wall of the water tank 10 is provided with a plurality of protrusions 121 arranged around the liquid level sensor 50, and the peripheral wall of the protective cover 60 is provided with a plurality of slots 61. The protrusions 121 engage with the corresponding slots 61, thus facilitating the stable installation of the protective cover 60 and achieving protection for the liquid level sensor 50.

[0072] Specifically, the inner top wall of the water tank 10 is provided with a latching protrusion 121, which includes a first part and a second part. The first part is connected to the inner top wall of the water tank 10 and extends downward. The second part is connected to the first part and extends away from the liquid level sensor 50. The upper end of the liquid level sensor 50 is connected to the inner top wall of the water tank 10. During installation, the protective cover 60 can be sleeved on the outside of the liquid level sensor 50 from the lower end. During this process, the multiple slots 61 on the protective cover 60 can correspond one-to-one with the multiple latching protrusions 121, thereby installing the protective cover 60 on the tank cover 12 and realizing the protection of the liquid level sensor 50.

[0073] In some embodiments of this utility model, the liquid level sensor 50 is configured as a float-type liquid level sensor 50, and the protective cover 60 has a connecting hole 62 on its peripheral wall. The connecting hole 62 is used to connect the inner and outer sides of the protective cover 60. In this way, the liquid level sensor 50 can accurately detect the liquid level of the water tank 10 and improve the detection accuracy.

[0074] Understandably, the core component of the float-type liquid level sensor 50 is the float. When the liquid level changes, the float moves up and down with the rise and fall of the liquid level. A permanent magnet is installed inside the float. When the liquid level changes, the buoyancy force on the float is different. The Hall sensor can detect the change of the permanent magnet on the float, thereby detecting the liquid level in the water tank 10. Therefore, in order to ensure the detection accuracy of the liquid level sensor 50, the protective cover 60 needs to be at the same liquid level. Therefore, a connecting hole 62 can be opened on the peripheral wall of the protective cover 60 to connect the inner and outer sides of the protective cover 60, thereby improving the detection accuracy of the liquid level sensor 50.

[0075] In some embodiments of this utility model, the water tank 10 includes a tank body 11 and a tank cover 12. The top of the tank body 11 is open, and the tank cover 12 is placed on the top of the tank body 11. The flow guiding component 40 is integrally formed with the tank cover 12. In this way, the integration and structural strength of the water tank assembly 100 can be improved, and the processing complexity of the water tank assembly 100 can be reduced.

[0076] In some embodiments of this utility model, the housing 11 is made of stainless steel. It can be understood that in order to improve the sterilization effect of the sterilization module 30, the sterilization module 30 is set as an ultraviolet sterilization lamp. In order to avoid the aging effect of ultraviolet sterilization lamp on the water tank 10, the housing 11 can be made of stainless steel. Compared with the plastic housing 11, the stainless steel housing 11 can withstand ultraviolet radiation better, ensuring the service life of the housing 11, and has a good antibacterial effect.

[0077] In some other embodiments of this utility model, the inner surface of the box cover 12 is coated with an anti-ultraviolet coating; it can be understood that in order to improve the sterilization effect of the sterilization module 30, the sterilization module 30 is set as an ultraviolet sterilization lamp, and in order to avoid the aging effect of the ultraviolet sterilization lamp on the box cover 12, an anti-ultraviolet coating can be provided on the inner surface of the box cover 12.

[0078] The UV-resistant coating can be understood as a coating containing UV absorbers (such as benzotriazoles or benzophenones), or as a functional coating (such as silica or zinc oxide) forming a nanometer-thick layer on the material surface. Of course, the foregoing should not be construed as limiting the scope of protection of this utility model.

[0079] like Figures 1 to 5According to the present utility model, the water purification device 1000 includes the water tank assembly 100 in the above embodiment. By applying the water tank assembly 100 in the above embodiment, the water purification device 1000 can provide users with clean drinking water and improve the user experience.
