Description
Technical Field
[0001] The utility model relates to the technical field of water purifiers, in particular to a water tank and a water purifier. Background Art
[0002] Currently, water purifiers on the market usually filter impurities in tap water through filter elements to obtain purified water. However, due to the limitations of booster pumps and filter membranes, the flow rate of purified water is generally not very large. The water flow rate of mainstream water purifiers is generally within 2L / min. In order to provide users with a better water experience and increase the water flow rate of the water purifier, there is currently a type of volumetric large-flow water purifier on the market. By setting a water tank in the water purifier, the filtered purified water is stored in the water tank, and then the water is delivered by a large-flow water delivery pump, thereby achieving a large-flow water output from the water purifier.
[0003] Although the above-mentioned volumetric large-flow water purification system can provide a large-flow water output, it is also easy to cause the problem of bacterial growth in the water tank. In order to solve the problem of bacterial growth in the water tank, a static UV sterilizer is usually installed in the water tank to kill the bacteria in the water tank or inhibit the growth of bacteria. However, since the water tank is usually made of food-grade plastic materials such as PP, the plastic material is prone to accelerated aging under the irradiation of the sterilizer, causing the inner wall of the water tank to turn yellow or even fall off. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the defect that the water tank shell of the water purifier in the prior art is easily aged under the irradiation of the sterilizing lamp, and to provide a water tank and a water purifier.
[0005] The utility model solves the above technical problems through the following technical solutions:
[0006] The utility model provides a water tank, characterized in that the water tank comprises a shell, a sterilization module and a flow guide cover;
[0007] The sterilization module and the flow guide cover are arranged in the outer shell. The sterilization module can generate light that kills bacteria. The flow guide cover is a hollow structure. The flow guide cover is provided with an opening connecting the inside and outside of the flow guide cover. The maximum irradiation range of the light generated by the sterilization module is at least partially located inside the flow guide cover.
[0008] In this solution, the water tank includes an outer shell, a sterilization module and a flow guide cover. The filtered clean water is stored in the outer shell. The sterilization module and the flow guide cover are arranged in the outer shell. The sterilization module is used to kill bacteria in the water tank. The sterilization module can generate light that kills bacteria. The flow guide cover is a hollow structure. The flow guide cover is provided with an opening connecting the inside and outside of the flow guide cover, so that water outside the flow guide cover can enter the inside of the flow guide cover for sterilization. The maximum illumination range of the light generated by the sterilization module is at least partially located inside the flow guide cover, so that the flow guide cover can at least partially block the light generated by the sterilization module, avoiding the light from being completely and directly irradiated on the outer shell, reducing the risk of aging and yellowing of the outer shell and the risk of the inner wall falling off, and extending the service life of the water tank.
[0009] Preferably, the sterilization module is arranged on the outside of the air guide cover, the sterilization module is arranged at one end of the air guide cover close to the opening, and the light generated by the sterilization module is irradiated toward the opening.
[0010] In the present solution, the sterilization module is arranged on the outside of the flow guide cover, and the sterilization module is arranged at one end of the flow guide cover close to the opening, and the light generated by the sterilization module is irradiated toward the opening, so that the light generated by the sterilization module can pass through the opening into the interior of the flow guide cover, and at the same time the flow guide cover can at least partially block the light generated by the sterilization module to prevent the light from directly irradiating the outer shell, thereby reducing the risk of aging and yellowing of the outer shell and falling off of the inner wall, and extending the service life of the water tank.
[0011] Preferably, the water tank further comprises a stirring assembly, wherein the stirring assembly is disposed in the housing, and the stirring assembly comprises a stirring rod and a motor, wherein the motor drives the stirring rod to rotate around itself.
[0012] In this solution, the motor drives the stirring rod to rotate around itself. The rotation of the stirring rod drives the water in the water tank to rotate, so that the water forms a water vortex, so that the water inside and outside the deflector can flow to each other, so that the sterilized water in the deflector and the unsterilized water outside the deflector are rotated, so that the water in the outer shell can be fully sterilized, thereby improving the sterilization effect of the water tank.
[0013] Preferably, the flow guide cover is arranged on the periphery of the stirring assembly.
[0014] In this solution, the water inside the deflector cover can be fully stirred by arranging the deflector cover on the periphery of the stirring assembly. Since the space inside the deflector cover is small, the water is more likely to form a water vortex, which makes the circulation effect between the water inside and outside the deflector cover better, further improving the sterilization effect of the water tank.
[0015] Preferably, the stirring rod includes a rotating shaft and a stirring head, one end of the rotating shaft is connected to the motor, the motor drives the rotating shaft to rotate, the stirring head is arranged at one end of the rotating shaft away from the motor, the stirring head includes a plurality of stirring parts, and the plurality of stirring parts are arranged at intervals along the circumference of the rotating shaft.
[0016] In this solution, the stirring head is arranged at the end of the rotating shaft away from the motor. The stirring head includes a plurality of stirring parts arranged at intervals along the circumference of the rotating shaft. By providing the stirring parts, the contact area between the stirring head and the water can be increased, so that the stirring head can stir the water better, the water can more easily form a water vortex, and the circulation effect between the water inside and outside the deflector cover is better, further improving the sterilization effect of the water tank.
[0017] Preferably, the stirring head further comprises a connecting portion, the connecting portion is connected to an end of the rotating shaft away from the motor, an extending direction of the connecting portion is not parallel to an axial direction of the rotating shaft, and the stirring portion extends obliquely outward from the connecting portion.
[0018] In the present solution, a connecting portion is provided on the stirring head, and the extending direction of the connecting portion is not parallel to the axial direction of the rotating shaft, thereby increasing the width of the stirring head. The stirring portion extends outwardly from the connecting portion at an angle, which can further increase the width of the stirring head, thereby increasing the range of the stirring head acting on the water, making it easier for the water to form a water vortex, thereby improving the circulation effect between the water inside and outside the deflector cover, and further enhancing the sterilization effect of the water tank.
[0019] Preferably, the air guide cover is cylindrical.
[0020] In this solution, by setting the flow guide cover to be cylindrical, the surface of the cylinder is smoother, and when the stirring component stirs the water, the resistance encountered by the water during rotation can be reduced, so that the flow effect between the water inside and outside the flow guide cover is better, and the sterilization effect of the water tank is further improved. In addition, since the water encounters less resistance during rotation, the energy consumption of the stirring component in stirring the water can also be reduced, so that the water tank has the effect of saving energy and reducing consumption.
[0021] Preferably, a side wall of the air deflector is provided with a notch, and the notch connects the inside and the outside of the air deflector.
[0022] In this solution, by setting a gap connecting the inside and outside of the deflector cover on the side wall, the water inside and outside the deflector cover can flow better, thereby improving the efficiency of the water circulation inside and outside the deflector cover, so that the water in the water tank can be fully sterilized in a shorter time, thereby improving the sterilization effect of the water tank.
[0023] Preferably, the water tank is further provided with an anti-overflow probe, and the anti-overflow probe is used to detect the overflow of water in the water tank;
[0024] And / or, the water tank is further provided with a liquid level detection device, and the liquid level detection device is used to detect the water level inside the water tank.
[0025] In this solution, an anti-overflow probe is also provided in the water tank. When the stirring assembly stirs the water in the water tank, the water may overflow from the water tank. The anti-overflow probe can detect the overflow of the water in the water tank, thereby preventing the water in the water tank from overflowing from the water tank.
[0026] The water tank is also provided with a liquid level detection device, which can detect the water level inside the water tank, so that the operation of the stirring component and the sterilization module can be adjusted according to the water level in the water tank to avoid the situation where the water is not fully sterilized or over-sterilized and energy is wasted.
[0027] The utility model also provides a water purifier, which comprises the water tank mentioned above.
[0028] In this solution, the water purifier has the same effect as the above-mentioned water tank.
[0029] The positive and progressive effects of the utility model are:

[0056] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the following embodiments.
[0057] This embodiment provides a water purifier, which includes a water tank 100 .
[0058] like Figure 1 and Figure 2As shown, the water tank 100 includes a housing 200, a sterilization module 300 and a flow guide 400. The filtered clean water is stored in the housing 200, and the housing 200 is provided with a water inlet 210 and a water outlet 220. The sterilization module 300 and the flow guide 400 are arranged in the housing 200. The sterilization module 300 is used to kill bacteria in the water tank 100. The sterilization module 300 can generate light that kills bacteria. The flow guide 400 is a hollow structure. The flow guide 400 is provided with an opening 410 connecting the inside and outside of the flow guide 400, so that the water outside the flow guide 400 can enter the inside of the flow guide 400 for sterilization. The maximum illumination range 310 of the light generated by the sterilization module 300 is at least partially located inside the deflector 400, so that the deflector 400 can at least partially block the light generated by the sterilization module 300, avoiding the light from directly irradiating the outer shell 200, reducing the risk of aging and yellowing of the outer shell 200 and the risk of the inner wall falling off, thereby extending the service life of the water tank 100.
[0059] like Figure 3 As shown, it should be specifically stated that the maximum illumination range 310 generated by the sterilization module 300 is completely located inside the shroud 400, so that the shroud 400 can completely block the light generated by the sterilization module 300 and prevent the light from directly irradiating the housing 200. In this embodiment, it is preferred that the maximum illumination range 310 of the light generated by the sterilization module 300 is exactly equal to the size of the opening 410 of the shroud 400, so that the size of the shroud 400 can be smaller, saving the materials required to manufacture the shroud 400 and reducing the production cost. In other embodiments, the maximum illumination range 310 of the light generated by the sterilization module 300 can also be smaller than the size of the opening 410 of the shroud 400, and the maximum illumination range 310 generated by the sterilization module 300 can also be completely located inside the shroud 400.
[0060] In other embodiments, the maximum illumination range 310 generated by the sterilization module 300 may be only partially located inside the air deflector 400, so that the air deflector 400 can partially block the light generated by the sterilization module 300 and prevent the light from directly irradiating the outer shell 200, thereby reducing the risk of aging and yellowing of the outer shell 200 and the risk of the inner wall falling off, thereby extending the service life of the water tank 100.
[0061] In this embodiment, the sterilization module 300 is arranged on the outside of the flow guide cover 400, and the sterilization module 300 is arranged at one end of the flow guide cover 400 close to the opening 410. The light generated by the sterilization module 300 is irradiated toward the opening 410, so that the light generated by the sterilization module 300 can be irradiated into the interior of the flow guide cover 400 through the opening 410. At the same time, the flow guide cover 400 can at least partially block the light generated by the sterilization module 300, and prevent the light from being completely and directly irradiated on the housing 200, thereby reducing the risk of aging and yellowing of the housing 200 and the risk of the inner wall falling off, and extending the service life of the water tank 100. In other examples, the sterilization module 300 can be arranged inside the flow guide cover 400, or on the flow guide cover 400, or other locations for the sterilization module 300 that are deemed appropriate by those skilled in the art can be selected.
[0062] The water tank 100 further includes a stirring assembly 500, which is disposed in the housing 200. The stirring assembly 500 includes a stirring rod 510 and a motor 520, and the motor 520 drives the stirring rod 510 to rotate around itself. The rotation of the stirring rod 510 drives the water in the water tank 100 to rotate, so that the water forms a water vortex, so that the water inside and outside the deflector 400 can flow to each other, so that the sterilized water in the deflector 400 and the unsterilized water outside the deflector 400 are rotated, so that the water in the housing 200 can be fully sterilized, thereby improving the sterilization effect of the water tank 100. A sealing structure 530 is provided between the motor 520 and the housing 200 to prevent water vapor from affecting the motor 520.
[0063] In this embodiment, the deflector 400 is disposed on the periphery of the stirring assembly 500, so that the water inside the deflector 400 can be fully stirred. Since the space inside the deflector 400 is small, the water is more likely to form a water vortex, so that the circulation effect between the water inside and outside the deflector 400 is better, further improving the sterilization effect of the water tank 100. In other embodiments, the stirring assembly 500 can also be disposed on the outside of the deflector 400, which can also play the role of stirring the water, so as to achieve the effect of mutual circulation of the water inside and outside the deflector 400.
[0064] like Figure 5 As shown, the stirring rod 510 includes a rotating shaft 511 and a stirring head 512. One end of the rotating shaft 511 is connected to the motor 520. The motor 520 drives the rotating shaft 511 to rotate. The stirring head 512 is arranged at one end of the rotating shaft 511 away from the motor 520. The stirring head includes a plurality of stirring parts 513. The plurality of stirring parts 513 are arranged at intervals along the circumference of the rotating shaft 511, thereby increasing the contact area between the stirring head 512 and water, making the stirring head 512 more effective in stirring water, making it easier for water to form a water vortex, and making the water flow between the inside and outside of the deflector 400 better, further improving the sterilization effect of the water tank 100.
[0065] The stirring head 512 also includes a connecting portion 514, which is connected to one end of the rotating shaft 511 away from the motor 520. The extending direction of the connecting portion 514 is not parallel to the axial direction of the rotating shaft 511, so that the width of the stirring head 512 can be increased. The stirring portion 513 extends outwardly from the connecting portion 514, which can further increase the width of the stirring head 512, increase the range of the stirring head 512 acting on the water, and the water is more likely to form a water vortex, so that the circulation effect between the water inside and outside the deflector 400 is better, and the sterilization effect of the water tank 100 is further improved. In other embodiments, the connecting portion 514 may not be provided, and the stirring portion 513 may be directly connected to the end of the rotating shaft 511 away from the motor 520.
[0066] In this embodiment, the stirring portion 513 extends obliquely upward toward the circumferential outer side of the rotating shaft 511. In other embodiments, the stirring portion 513 may also extend obliquely downward toward the circumferential outer side of the rotating shaft 511, or other extension directions of the stirring portion 513 deemed appropriate by those skilled in the art may be selected.
[0067] In this embodiment, the deflector 400 is cylindrical, and the surface of the cylinder is smoother. When the stirring assembly 500 stirs the water, the resistance of the water during rotation can be reduced, so that the water inside and outside the deflector 400 can flow better, further improving the sterilization effect of the water tank 100. In addition, since the resistance of the water during rotation is smaller, the energy consumption of the stirring assembly 500 for stirring the water can also be reduced, so that the water tank 100 has the effect of energy saving and consumption reduction. In other embodiments, those skilled in the art can also select other suitable shapes of the deflector 400 as needed.
[0068] like Figure 4 As shown, the side wall of the air deflector 400 is provided with a notch 420, and the notch 420 connects the inside and the outside of the air deflector 400, so that the water inside and the outside of the air deflector 400 can flow better, thereby improving the efficiency of the water circulation inside and the outside of the air deflector 400, so that the water in the water tank 100 can be fully sterilized in a shorter time, thereby improving the sterilization effect of the water tank 100.
[0069] In this embodiment, the notch 420 is provided at the upper part of the side wall of the deflector 400, and cooperates with the opening 410 at the lower end of the deflector 400, so that water can flow better inside and outside the deflector 400. In other embodiments, the notch 420 can also be provided in the middle of the side wall of the deflector 400, or other positions of the notch 420 deemed appropriate by those skilled in the art can be selected. Those skilled in the art can select the appropriate number and shape of the notch 420 as needed.
[0070] The water tank 100 is also provided with an anti-overflow probe 600, which is used to detect the overflow of water in the water tank 100. When the stirring assembly 500 stirs the water in the water tank 100, the water may overflow the water tank 100, and the anti-overflow probe 600 can detect the overflow of the water in the water tank 100, thereby preventing the water in the water tank 100 from overflowing the water tank 100.
[0071] The water tank 100 is also provided with a liquid level detection device 700, which is used to detect the water level inside the water tank 100, so that the operation of the stirring assembly 500 and the sterilization module 300 can be adjusted according to the water level in the water tank 100 to avoid the situation where the water is not fully sterilized or over-sterilized to waste energy.
