Description

Technical Field

[0001] The utility model relates to the technical field of water dispensers, in particular to a pull - out structure of a cleaning tank of a water dispenser. Background Art

[0002] The water receiving box of a water dispenser is mainly used to prevent drinking water from splashing or overflowing when users receive water, so as to avoid wetting or soiling the ground. Existing water dispensers usually have a water receiving box. In the prior art, the water receiving box is set as a pull - out type, and a water suction pipe is arranged above the water receiving box. The water suction port of the water suction pipe contacts the bottom of the water receiving box. The water suction pipe is used to pump the water in the water receiving box to the sterilization and filtration unit to form purified water for the purpose of wastewater utilization. However, due to the lack of a cleaning device in the water receiving box, bacteria will breed at the bottom of the water receiving box after the wastewater has accumulated for a long time. When the water level in the water receiving box reaches the upper limit, the water receiving box needs to be manually pulled out and cleaned inside. However, during the process of pulling out the water receiving box, the bottom of the water receiving box will contact and rub against the water suction port of the water suction pipe, scraping the bacteria on the bottom of the water receiving box onto the water suction port of the water suction pipe, resulting in the pollution of the water suction pipe. Therefore, there is an urgent need to develop a water dispenser that can prevent the bottom of the water receiving box from contacting the water suction port of the water suction pipe when the water receiving box is pulled out. Content of the Utility Model

[0003] The purpose of the utility model is to provide a pull - out structure of a cleaning tank of a water dispenser, which has the effect that when the water receiving box is pulled outwards, the water inlet end of the water suction pipe automatically lifts away from the water receiving box, effectively preventing the wear and bacteria contamination caused by the contact between the water inlet end of the water suction pipe and the bottom of the water receiving box when the water receiving box is pulled.

[0004] The above - mentioned technical purpose of the utility model is achieved through the following technical solutions: A pull - out structure of a cleaning tank of a water dispenser includes a water dispenser main body. The water dispenser main body is provided with a pull - out water receiving box. The water dispenser main body is provided with a water pumping structure corresponding to the water receiving box. The water pumping structure includes a water suction pipe rotatably arranged on the water dispenser main body. A linkage structure is arranged between the water suction pipe and the water receiving box. When the water receiving box is pulled, under the linkage action of the linkage structure, the water suction pipe is driven to rotate and its water inlet end is relatively far away from the bottom of the water receiving box.

[0005] By adopting the above technical solution, during the process of pulling out the water receiving box from the water dispenser main body, under the linkage effect of the linkage structure between the water receiving box and the water suction pipe, the water suction pipe is driven to rotate so that its water inlet end is lifted upward relative to the water receiving box, and then the water inlet end of the water suction pipe gradually moves away from the bottom of the water receiving box. In this way, during the process of pulling out the water receiving box outward, the water inlet end of the water suction pipe will never contact the bottom of the box cavity of the water receiving box, avoiding the situation that the water inlet end of the water suction pipe and the bottom of the water receiving box are damaged due to mutual friction when the water receiving box is pulled out outward. In addition, bacteria are likely to grow on the bottom of the box cavity of the water receiving box after long-term use, and the setting of the linkage structure also avoids the situation that the water inlet end of the water suction pipe contacts the bottom of the water receiving box when the water receiving box is pulled out outward and gets contaminated with bacteria. It has the effect that the water inlet end of the water suction pipe automatically lifts upward and away from the water receiving box during the process of pulling out the water receiving box outward, effectively preventing the wear and bacterial contamination caused by the contact between the water inlet end of the water suction pipe and the bottom of the water receiving box when the water receiving box is pulled out.

[0006] A further setting of the present utility model is that: the linkage structure includes a push rod portion fixedly arranged in the radial direction of the water suction pipe, and the water receiving box is in push cooperation with the push rod portion.

[0007] By adopting the above technical solution, when the water receiving box is pulled out outward relative to the water dispenser main body, the rear wall of the water receiving box touches and pushes the push rod portion, and the push rod portion drives the water suction pipe to rotate so that the water inlet end of the water suction pipe automatically moves away from the bottom of the box cavity of the water receiving box.

[0008] A further setting of the present utility model is that: a transfer sleeve is connected to the water outlet end of the water suction pipe, a push rod portion is arranged to extend in the radial direction of the transfer sleeve, the water receiving box is in push cooperation with the push rod portion, and shaft portions are arranged radially on both sides of the transfer sleeve. The water dispenser main body is provided with an installation portion, and a through hole is opened in the installation portion corresponding to the shaft portions, and the shaft portions are rotatably installed in the through holes.

[0009] By adopting the above technical solution, the transfer sleeve is used to detachably install the water suction pipe to the transfer sleeve, which is convenient for subsequent disassembly and replacement of the water suction pipe. When the water receiving box is installed in place on the water dispenser main body, the water inlet end of the water suction pipe automatically hangs down by gravity, realizing the connection between the water inlet end of the water suction pipe and the solution at the bottom of the water receiving box. When the water receiving box is pulled out outward, the linkage structure is used to drive the transfer sleeve to rotate along the through hole through its shaft portions, so that the water pumping port of the water suction pipe automatically moves away from the bottom of the water receiving box.

[0010] A further setting of the present utility model is that: an anti - detachment portion is arranged at one end of the shaft portion away from the water suction pipe. When the shaft portion is rotatably connected in the through hole, the shaft portion is in anti - detachment cooperation with the through hole through the anti - detachment portion.

[0011] By adopting the above technical solution, the addition of the anti - detachment portion can effectively prevent the situation that the shaft portion of the water suction pipe accidentally detaches from the through hole during the use of the present utility model.

[0012] A further arrangement of the utility model is that a liquid level detection device is provided on the water receiving box. The liquid level detection device includes a floating ball and a sensor assembly. The floating ball is floatingly arranged in the water receiving box, and the sensor assembly is in inductive cooperation with the floating ball.

[0013] By adopting the above technical solution, the floating ball will rise and fall synchronously with the liquid level in the water receiving box, and the sensor assembly realizes real-time monitoring of the liquid level of the water receiving box by sensing the position of the floating ball.

[0014] A further arrangement of the utility model is that the main body of the water dispenser includes a base frame. The base frame is provided with a communicating accommodating cavity and a water leakage hole. The water receiving box is slidably arranged in the accommodating cavity, and when the water receiving box is received in the accommodating cavity, the water leakage hole is aligned and communicated with the water receiving box.

[0015] A further arrangement of the utility model is that a plurality of convex ribs are provided at the bottom of the water receiving box. The water receiving box is slidably engaged with the base frame through the plurality of convex ribs.

[0016] By adopting the above technical solution, the addition of the convex ribs can reduce the contact area between the bottom of the water receiving box and the base frame, thereby improving the smoothness of the water receiving box sliding on the base frame.

[0017] A further arrangement of the utility model is that an avoidance hole is provided on one side of the base frame corresponding to the water outlet end of the water extraction pipe. The water extraction pipe is in avoidance cooperation with the avoidance hole.

[0018] By adopting the above technical solution, the avoidance hole can effectively avoid the rotating water extraction pipe, preventing the situation that the water extraction pipe cannot rotate in place and gets stuck.

[0019] A further arrangement of the utility model is that a handle is provided on the front end face of the water receiving box.

[0020] By adopting the above technical solution, the addition of the handle improves the convenience for users to pull out the water receiving box.

[0021] A further arrangement of the utility model is that the water receiving box is provided with a water outlet structure. The water outlet structure includes a one-way valve and a water outlet hose. The water inlet end of the water outlet hose is communicated with the inner cavity of the water receiving box through the one-way valve.

[0022] By adopting the above technical solution, the water outlet structure can assist the water extraction structure to realize multi-point water outlet of the water receiving box. The addition of the one-way valve can effectively prevent the water in the water outlet hose from flowing back into the water receiving box. At the same time, by using the flexibility of the water outlet hose, the water outlet hose can be flexibly bent when the water receiving box is pulled out.

[0023] In summary, the utility model has the following beneficial effects:

[0024] The water receiving box is arranged in a pull-out manner on the main body of the water dispenser, and a water pumping structure is provided on the main body of the water dispenser corresponding to the water receiving box. The water pumping structure includes a water pumping pipe, a rotating shaft portion is fixedly arranged radially on the water pumping pipe, the water pumping pipe is rotatably connected to the main body of the water dispenser through the rotating shaft portion, and a linkage structure is arranged between the water pumping pipe and the water receiving box. When the water receiving box is pulled outwards, under the linkage action of the linkage structure, the water pumping pipe is driven to rotate and its water inlet end is relatively far away from the bottom of the water receiving box. In this way, during the process of pulling out the water receiving box outwards, the water inlet end of the water pumping pipe will never contact the bottom of the cavity of the water receiving box, avoiding the situation that the water inlet end of the water pumping pipe and the bottom of the water receiving box are damaged due to mutual friction when the water receiving box is pulled outwards. In addition, bacteria are likely to breed on the bottom of the cavity of the water receiving box after long-term use, and the setting of the linkage structure also avoids the situation that the water inlet end of the water pumping pipe contacts the bottom of the water receiving box and contaminates bacteria when the water receiving box is pulled outwards. It has the effect that the water inlet end of the water pumping pipe automatically lifts away from the water receiving box during the process of pulling out the water receiving box outwards, effectively preventing the wear and contamination of bacteria caused by the contact between the water inlet end of the water pumping pipe and the bottom of the water receiving box when the water receiving box is pulled out.

[0032] The present utility model will be further described below in conjunction with the accompanying drawings.

[0033] A pull-out structure of a cleaning tank for a water dispenser, as Figure 1-2 shown, includes a water dispenser main body 1. A water receiving box 2 is provided in a pull-out manner on the water dispenser main body 1. A water pumping structure is provided on the water dispenser main body 1 corresponding to the water receiving box 2. The water pumping structure includes a water pumping pipe 21 rotatably provided on the water dispenser main body 1. The water outlet end of the water pumping pipe 21 is connected with a water pumping hose 214. A linkage structure is provided between the water pumping pipe 21 and the water receiving box 2. When the water receiving box 2 is pulled out, under the linkage action of the linkage structure, the water pumping pipe 21 is driven to rotate and its water inlet end moves relatively away from the bottom of the water receiving box 2. The water dispenser main body 1 is provided with a water outlet faucet 10. When receiving water, the water leaking from the water outlet faucet 10 will directly fall into the water receiving box 2. A handle 24 is provided on the front end face of the water receiving box 2. The addition of the handle 24 improves the convenience of the user to pull out the water receiving box 2.

[0034] As Figure 2-5 shown, the water outlet end of the water pumping pipe 21 is connected with an adapter sleeve 20. The linkage structure includes a push rod portion 211 extending in the radial direction of the adapter sleeve 20. The rear wall of the water receiving box 2 is in pushing cooperation with the push rod portion 211. When the water receiving box 2 is pulled outwards relative to the water dispenser main body 1, the rear wall of the water receiving box 2 touches and pushes the push rod portion 211. The push rod portion 211 drives the water pumping pipe 21 to rotate so that the water inlet end of the water pumping pipe 21 automatically moves away from the bottom of the cavity of the water receiving box 2. And two sides of the adapter sleeve 20 are radially provided with rotating shaft portions 212. The water dispenser main body 1 is provided with an installation portion 31. The installation portion 31 is provided with a through hole 31a corresponding to the rotating shaft portion 212. The rotating shaft portion 212 is rotatably installed in the through hole 31a. The adapter sleeve 20 is used to detachably install the water pumping pipe 21 to the adapter sleeve 20, which is convenient for subsequent disassembly and replacement of the water pumping pipe 21. When the water receiving box 2 is installed in place on the water dispenser main body 1, the water inlet end of the water pumping pipe 21 automatically hangs down by gravity, realizing the connection between the water inlet end of the water pumping pipe 21 and the solution at the bottom of the water receiving box 2. When the water receiving box 2 is pulled outwards, the linkage structure is used to drive the adapter sleeve 20 to rotate along the through hole 31a through its rotating shaft portion 212, so that the water pumping port of the water pumping pipe 21 automatically moves away from the bottom of the water receiving box 2. In other embodiments, the adapter sleeve 20 and the water pumping pipe 21 can also be set as a whole, and the distance between the water pumping port end of the water pumping pipe 21 and the rotating shaft portion 212 is greater than the distance between the other end of the adapter sleeve 20 or the water pumping pipe 21 and the rotating shaft portion 212, so that the center of gravity of the water pumping pipe 21 is always close to its water pumping port end. An anti-detachment portion 213 is provided at one end of the rotating shaft portion 212 away from the water pumping pipe 21. When the rotating shaft portion 212 is rotatably connected in the through hole 31a, the rotating shaft portion 212 is in anti-detachment cooperation with the through hole 31a through the anti-detachment portion 213. The addition of the anti-detachment portion 213 can effectively prevent the rotating shaft portion 212 of the water pumping pipe 21 from accidentally detaching from the through hole 31a during the use of the present utility model.

[0035] AsFigure 1-6 As shown in the figure, the water dispenser main body 1 includes a base frame 3. The base frame 3 is communicatively provided with a receiving cavity 3a and a water leakage hole 3b. The water receiving box 2 is slidably arranged in the receiving cavity 3a. When the water receiving box 2 is received in the receiving cavity 3a, the water leakage hole 3b is aligned and communicated with the water receiving box 2. A plurality of convex ribs 23 are provided at the bottom of the water receiving box 2. The water receiving box 2 is slidably matched with the base frame 3 through the plurality of convex ribs 23. The addition of the convex ribs 23 can reduce the contact area between the bottom of the water receiving box 2 and the base frame 3, thereby improving the smoothness of the water receiving box 2 sliding on the base frame 3. The addition of the convex ribs 23 can reduce the contact area between the bottom of the water receiving box 2 and the base frame 3, thereby improving the smoothness of the water receiving box 2 sliding on the base frame 3. The avoidance hole 3c can effectively avoid the rotating water suction pipe 21. When the water inlet port of the water suction pipe 21 is tilted downward by gravity, causing the water suction pipe 21 to rotate, at this time, one end of the water outlet port of the water suction pipe 21 drives the water suction hose 214 to tilt upward through the avoidance hole 3c.

[0036] As Figure 6 As shown in the figure, the water receiving box 2 is provided with a liquid level detection device 22. The liquid level detection device 22 includes a floating ball 221 and a sensor assembly 222. The floating ball 221 is floatingly arranged in the water receiving box 2. The sensor assembly 222 is inductively matched with the floating ball 221. The floating ball 221 will rise and fall synchronously with the liquid level in the water receiving box 2. The sensor assembly 222 realizes the real-time monitoring of the liquid level of the water receiving box 2 by sensing the position of the floating ball 221. In this embodiment, the sensor assembly 222 is set as a Hall sensor, and a magnetic block is provided in the floating ball 221.

[0037] The basic working principle of the present utility model is as follows: The water receiving box 2 is provided in a pull-out manner on the water dispenser main body 1, and the water dispenser main body 1 is provided with a water pumping structure corresponding to the water receiving box 2. The water pumping structure includes a water suction pipe 21. A rotating shaft portion 212 is radially fixed on the water suction pipe 21. The water suction pipe 21 is rotatably connected to the water dispenser main body 1 through the rotating shaft portion 212. At the same time, a linkage structure is provided between the water suction pipe 21 and the water receiving box 2. When the water receiving box 2 is pulled outwards, under the linkage action of the linkage structure, the water suction pipe 21 is driven to rotate and its water inlet end is relatively far away from the bottom of the water receiving box 2. In this way, during the process of pulling out the water receiving box 2 outwards, the water inlet end of the water suction pipe 21 will never contact the bottom of the cavity of the water receiving box 2, avoiding the situation that the water inlet end of the water suction pipe 21 and the bottom of the water receiving box 2 are damaged due to mutual friction when the water receiving box 2 is pulled outwards. In addition, bacteria are likely to breed at the bottom of the cavity of the water receiving box 2 after long-term use. The setting of the linkage structure also avoids the situation that the water inlet end of the water suction pipe 21 contacts the bottom of the water receiving box 2 and contaminates bacteria when the water receiving box 2 is pulled outwards. It has the effect of automatically lifting the water inlet end of the water suction pipe away from the water receiving box during the process of pulling out the water receiving box outwards, effectively preventing the wear and contamination of bacteria caused by the contact between the water inlet end of the water suction pipe and the bottom of the water receiving box when the water receiving box is pulled out.
