Description

Technical Field

[0001] The present application relates to the technical field of pet supplies, and in particular to a pet drinking fountain. Background Art

[0002] With the development of humanities, more and more people are keeping pets and paying more and more attention to their pets' health. Water is indispensable in pets' daily lives. To ensure that pets have enough healthy water to drink, the traditional method is to manually change and replenish water. The frequent replenishment mode is not suitable for commercial use and for home use where pets need to live independently for a long time. Manual operation may introduce contamination, and contaminated water will breed a large number of bacteria after being left for a long time, which will affect the health of pets. Therefore, smart water dispensers have emerged, which rely on electricity and control systems to supply and pour water, realize water circulation and change, and solve the problems caused by traditional drinking water methods. For example, CN220383950U, however, its water supply and pouring both rely on electricity, which requires a lot of power resources. Direct use of mains electricity will have certain usage limitations due to wiring problems. When using batteries, the longer the battery life, the larger the battery capacity, and the product cost will also increase accordingly. Moreover, since the water supply and pouring processes both rely on electricity resources, a corresponding drive structure needs to be configured, which makes the structure larger and the cost increases. Summary of the Invention

[0003] In view of this, the present application provides a pet drinking fountain to solve the technical problems of high cost and large size of existing pet drinking fountains that automatically replenish and change water.

[0006] Furthermore, the radial cross-section of the water storage chamber is V-shaped.

[0007] Furthermore, the pre-turning force of the turnable water receiving tray can be formed by the torque generated by the different gravity on both sides of the rotation axis and / or the elastic force acting thereon.

[0008] Furthermore, the gravity on both sides of the rotating shaft of the flip water receiving tray is unbalanced. When the flip water receiving tray is reset, the end of the flip water receiving tray with greater gravity abuts against the corresponding bracket part.

[0009] Furthermore, it also includes a table top, which is fixedly installed on the upper water tank, and the table top is detachably connected to the lower water tank. The flip water receiving tray and the blocking structure are both arranged on the table top.

[0010] Furthermore, the table has a through mounting hole, and axial slots opening upward are provided on the opposite sides of the mounting hole. The rotating shaft of the flip water receiving tray is placed in the corresponding axial slots so that the flip water receiving tray is located in the mounting hole.

[0011] Furthermore, the lower water tank is barrel-shaped, and the platform is snap-fitted and connected to the upper opening of the lower water tank.

[0012] Furthermore, the upper water tank is composed of an inner box body and an openable upper cover body, and the water outlet structure includes a water outlet pipe fixedly connected to the inner box body and a valve core arranged at the water outlet of the water outlet pipe, and the flow rate is adjusted by adjusting the valve core.

[0013] Furthermore, the valve core includes a coaxially arranged regulating cover and a core shaft, the internal thread of the regulating cover is threadedly connected to the connector of the outlet pipe, and the water flow rate is adjusted by adjusting the insertion depth of the core shaft, and the regulating cover has a drainage hole.

[0014] Furthermore, the water outlet pipe also includes a water inlet, which is connected to the water outlet through an adjustment port, the core shaft cooperates with the adjustment port to adjust the flow rate, and the core shaft is clearance-matched with the water outlet.

[0015] Furthermore, the water outlet structure also includes a protection tube sleeved on the water outlet pipe, and the valve core is located in the protection tube.

[0016] Furthermore, the upper water tank is composed of an outer shell with an open top, an inner box body placed in the outer shell along the top opening, and an openable upper cover body covering the upper opening of the inner box body. The water outlet structure includes a water outlet pipe arranged on the outer shell and an electric valve, a connecting water pipe, a circuit board and a battery arranged together between the outer shell and the inner box body. The circuit board is electrically connected to the electric valve and the battery. The water inlet of the electric valve is connected to the inner box body through the connecting water pipe, and the water outlet of the electric valve is connected to the water outlet pipe.

[0017] Furthermore, a window for disassembling and installing the battery is provided on the shell.

[0018] Furthermore, the side of the flip water receiving tray that tends to descend under the action of the pre-flip force also has a water storage chamber, and the volume of the water storage chamber on the side of the flip water receiving tray that tends to rise under the action of the pre-flip force is larger than the volume of the water storage chamber on the side that tends to descend under the action of the pre-flip force, and the water storage chambers on both sides are connected to each other.

[0019] It can be seen from the above technical solution that the advantages of the present invention are: 1. In the present application, continuous water supply can be achieved by controlling the water outlet structure of a purely mechanical structure. Water is collected by using the provided flip water receiving tray. When the water volume is sufficient or when the pet accidentally overturns it, a driving flipping force can be generated to flip the flip water receiving tray to clean the water stored in the flip water receiving tray for a long time. The flip water receiving tray can continue to receive new water after being reset by the pre-flipping force, so that the pet's drinking water can be replaced in time, avoiding the problem of long-term accumulation of contaminated water, and improving the safety of pet drinking water. The entire working process does not require electricity, which improves the convenience and reliability of use.

[0020] 2. The counterweight part and the corresponding bracket part provided in this application enable the flip water receiving tray to be stably supported on the bracket part when resetting, so that the flip water receiving tray maintains a stable horizontal state when receiving water, ensuring that the pet can easily draw water. At the same time, the interval time for water change can also be adjusted according to the weight and position design of the counterweight part.

[0021] 3. The structure of this application is simple, and the detachable lower water tank and flip water receiving tray make cleaning, maintenance and replacement convenient, and it is easy to disassemble and assemble and easy to use.

[0022] 4. When the present application adopts a water outlet structure with an electric valve to supply water, the water outlet process is more stable, and the flipping action of the water receiving tray is still realized by its own pre-flipping force and the flipping driving force generated by the water stored in the water tray, which saves the flipping driving mechanism, reduces the size of the body, and reduces power consumption. The battery capacity required for the same battery life is smaller, which further reduces the body volume and reduces product costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail in conjunction with the embodiments and drawings. Here, the illustrative embodiments of this application and their descriptions are used to explain this application, but are not intended to limit this application.

[0035] Example 1 refer to Figures 1 to 5 ,like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 When the amount of water in the water collecting pan 4 is insufficient, the water in the water collecting pan 4 will be pressed against the blocking structure under the action of the pre-turning force to put it in a water collection and reset state, and the water collecting pan 4 will be in a position to receive the water out of the water outlet structure 5; when the amount of water stored in the water collecting pan 4 is sufficient, the water stored in the water collecting pan 4 will generate a driving turning force on the water collecting pan 4 that is greater than the pre-turning force and in the opposite direction of the pre-turning force. The water collecting pan 4 will turn over and pour out the water under the driving turning force, and the lower water tank 1 will be in a position to receive the water poured out by the water collecting pan 4; After the water is poured out, the water in the flip water receiving pan 4 will be poured into the lower water tank 1 for storage. After the pouring is completed, the flip water receiving pan 4 will automatically return to its initial position (water receiving position) under the action of the pre-turning force. The process of repeatedly collecting water, pouring water, and collecting water is used to avoid water accumulating in the open flip water receiving pan 4 for a long time and breeding bacteria, ensuring that the pet can always drink fresh and clean water. In addition, the gravity effect is utilized during the working process without relying on electricity resources, which meets the function of timely changing the water source. At the same time, the structure is simple and the cost is low.

[0036] One distribution form of the water storage chamber of the flip water receiving tray 4 of the present application is that the water storage chambers are all located on the side of the flip water receiving tray 4 that tends to rise under the action of the pre-flip force. When the amount of water in the water storage chamber is sufficient, a driving flipping force will be generated to drive it to flip and pour water.

[0037] Another distribution form of the water storage chamber of the flip water receiving tray 4 of the present application is: the water storage chamber of the flip water receiving tray 4 is unevenly distributed on both sides of the rotating shaft 41 of the flip water receiving tray 4, and the water storage volume of the water storage chamber of the flip water receiving tray 4 on the side that tends to rise under the action of the pre-turning force is greater than the water storage volume on the side that tends to fall under the action of the pre-turning force. Because the volumes of the water storage chambers on both sides of the rotating shaft of the flip water receiving tray 4 are different, the water in the water storage chamber will make the gravity of the flip water receiving tray 4 on both sides of the rotating shaft uneven, resulting in driving it to flip and pour water. driving flipping force; by arranging water storage chambers on both sides of the rotating shaft 41, the water storage capacity of the flip water receiving tray 4 is increased, and the required pre-flipping force is small. Moreover, by arranging water storage chambers on both sides of the rotating shaft 41, the water stored in the water storage chamber on the side of the flip water receiving tray 4 that tends to descend under the action of the pre-flipping force can generate a counter-driving flipping force in the opposite direction to the driving flipping force (the same direction as the pre-flipping force), thereby increasing the resistance that the driving flipping force needs to overcome, making the flip water receiving tray 4 more stable during the water receiving process, and also reducing the flipping frequency of the flip water receiving tray 4.

[0038] In the present application, the water storage chambers on both sides of the rotating shaft 41 of the flip water receiving tray 4 are interconnected, and a single water outlet structure 5 can meet the water filling needs. The structure is simple, and the water outlet structure 5 is located above the side of the flip water receiving tray 4 that tends to rise under the action of the pre-flipping force. When the flip water receiving tray 4 is flipped and pouring water under the action of the driving flipping force, it will not interfere with the water outlet structure 5.

[0039] When the water storage chambers on both sides of the rotating shaft 41 of the flip water receiving tray 4 are not connected to each other, the length of the water outlet structure 5 above the side of the flip water receiving tray 4 that tends to descend under the action of the pre-flipping force is shortened and does not interfere with the flip water receiving tray 4. The body of the pet water dispenser is provided with a guide groove located below the water outlet structure 5. The water flowing out through the corresponding water outlet structure 5 enters the guide groove. When the flip water receiving tray 4 is reset to the water receiving position, the water passing through the guide groove will enter the corresponding water storage chamber.

[0040] In the present invention, the pre-flipping force possessed by the flip water receiving tray 4 can be formed by the different gravity on both sides of its rotating shaft 41 and / or the torque generated by the elastic force acting thereon. When the pre-flipping force is formed by the torque generated by the elastic force, the elastic force can be generated by a torsion spring or a coil spring arranged at the rotating shaft 41 or a tension spring connected between the flip water receiving tray 4 and the blocking structure.

[0041] In this embodiment, preferably, the flip water receiving tray 4 generates a pre-flipping force due to the uneven weight distribution of the flip water receiving tray 4 on both sides of the rotating shaft.

[0042] In the present invention, the weight of the flip water receiving tray 4 distributed on both sides of the rotating shaft is uneven, which will make the gravity on both sides of the rotating shaft uneven, thereby making it have a pre-flipping force that can automatically flip and reset to the water receiving state; the water storage chambers on both sides of the rotating shaft of the flip water receiving tray 4 have different volumes. At the same water level, the weight of the water in the large-volume water storage chamber is greater than the weight of the water in the small-volume water storage chamber. During the water filling process, the gravity on the large-capacity water storage chamber side increases faster, and the gravity on the small-capacity water storage chamber side increases slower, so that the gravity on both sides of the rotating shaft 41 is uneven. The forces first approach equilibrium. Before the gravity on both sides reaches equilibrium, in the absence of external interference, the flip water receiving tray 4 will always be in a stable water receiving state. First, it can ensure that a certain amount of water can be stored in the water storage chamber of the flip water receiving tray 4 before it flips over. Second, it can ensure that when the pet is drinking water, a certain amount of water can be stored in the water storage chamber of the flip water receiving tray 4 before it flips over stably, ensuring that the pet can drink water smoothly. When the gravity on both sides crosses the equilibrium point, the gravity on one side of the large-capacity water storage chamber increases faster than the other side, thereby generating a driving flipping force in the opposite direction of the pre-flipping force.

[0043] In the present application, the blocking structure may also be omitted. The flip water receiving tray 4 adopts a structural scheme with inconsistent volumes on both sides of the rotating shaft, so that the weight on both sides of the structure itself is unbalanced. The flip water receiving tray 4 is deeper, and the rotating shaft is located at the upper part of the flip water receiving tray 4. When resetting, the flip water receiving tray 4 rotates to a certain angle toward the heavier side. During the water filling process, the flip water receiving tray 4 will have a period of dynamic balance. When the water level is higher than a certain height, the balance will be broken to ensure that a certain amount of water can be stored in the water storage chamber of the flip water receiving tray 4 before it is flipped. Although it can meet the problem of water change, it has certain instability and is greatly affected by external forces.

[0044] Since the gravity on both sides of the rotating shaft of the flip water receiving tray 4 is unbalanced, in order to keep the flip water receiving tray 4 stable during the reset water receiving process, a blocking structure is used to support the flip water receiving tray 4 after reset. When the flip water receiving tray 4 is reset, the heavier end of the flip water receiving tray 4 is against the corresponding blocking structure to maintain balance.

[0045] In order to adjust the amount of water stored in the flip water receiving tray 4, in the present invention, the heavier end of the flip water receiving tray 4 is provided with a counterweight portion 42. By increasing the counterweight, the pre-flipping force of the flip water receiving tray 4 is increased, the required driving flipping force is increased, and the water storage capacity is increased. When the flip water receiving tray 4 is reset, the side of the flip water receiving tray 4 with the counterweight portion 42 will be against the blocking structure. The support and limiting effect of the blocking structure are utilized to ensure that the flip water receiving tray 4 can be stably in a horizontal water receiving state before being flipped over to pour water. The flip water receiving tray 4 can always remain in a horizontal state before automatically flipping over to pour water, which is convenient for pets to drink water. After the flip water receiving tray 4 is completed, it is only necessary to adjust the water storage capacity by adjusting the size of the counterweight portion 42, and there is no need to change the structure of the water storage cavity of the flip water receiving tray 4.

[0046] Specifically, in the present invention, the flip water receiving tray 4 includes a V-shaped water storage cavity with asymmetric structures on both sides and a V-shaped radial cross-section. Figure 1 、 Figure 2 The direction of the middle flip water receiving tray 4 is the reference direction. The length of the right water storage chamber 44 on the right side of the rotating shaft of the flip water receiving tray 4 is greater than the length of the left water storage chamber 43 on the left side of the rotating shaft of the flip water receiving tray 4 (that is, the bottom slope of the right water storage chamber 4 is gentler). Since the depth and width are consistent, the volume of the right water storage chamber 44 is greater than the volume of the left water storage chamber 43. The counterweight 42 is located on the left side. When the amount of water in the flip water receiving tray 4 is insufficient (the water level is less than the preset height), the gravity on the left side of the flip water receiving tray 4 is greater than that on the right side, generating a pre-flipping force that keeps the counterweight 42 and the blocking structure in a resisting state, and the flip water receiving tray 4 is stably in the water receiving position; when the amount of water in the flip water receiving tray 4 is sufficient (the water level exceeds the preset height), the gravity on the right side of the flip water receiving tray 4 is greater than that on the left side, generating a pre-flipping force that keeps the counterweight 42 and the blocking structure in a resisting state, and the flip water receiving tray 4 is stably in the water receiving position. The driving flipping force causes the right side of the flip water receiving tray 4 to descend and deflect. During the deflection process, the water in the left water storage chamber 43 will be transferred to the right water storage chamber 44 due to gravity, so that the gravity on the right side will increase rapidly in a short time, which will increase the driving flipping force, and then the flip water receiving tray 4 will quickly flip downward at a large angle. Since the water storage chamber is a V-shaped structure, the water stored in the flip water receiving tray 4 will be quickly emptied during the downward flipping process of the flip water receiving tray 4. After the flip water receiving tray 4 is emptied, the driving flipping force disappears or is greatly reduced. The flip water receiving tray 4 will quickly return to the water receiving position under the action of the pre-flipping force to continue receiving water, waiting for the next flip. Repeated pouring of water can effectively avoid the problem of long-term accumulation of water that is prone to breeding bacteria, ensuring that pets can drink clean water at any time.

[0047] In the present invention, a structure of the pet drinking fountain is as follows: the flip water receiving tray 4 and the upper water tank 3 can be installed through the base body, and the lower water tank 1 can be placed under the flip water receiving tray 4 by pulling out. When the lower water tank 1 needs to be cleaned, the water outlet structure 5 is closed, and the lower water tank 1 can be directly pulled out for cleaning. The flip water receiving tray 4 and the upper water tank 3 can remain in place, but there are defects such as the center of gravity of the base being too high and unstable, and the lower water tank 1 being light in weight in the initial stage of receiving water and easily pushed over by pets, which poses certain risks when used.

[0048] In this embodiment, the pet water dispenser preferably further comprises a table 2, which is fixedly mounted to the bottom of the upper water tank 3 by fasteners such as bolts and pins. The table 2 and the lower water tank 1 are detachably connected, making installation and removal convenient for the user. The flip water receiving tray 4 is mounted on the table 2, and the blocking structure is located on the table 2. When in use, the lower water tank 1, the table 2, the flip water receiving tray 4 and the upper water tank 3 are integrated into a structure, making the structure stable and easy to move, and also facilitating the replacement and cleaning of different components.

[0049] In an embodiment of the present application, the table top 2 also has a plurality of hollow holes, which can allow water spilled on the table top 2 to flow into the lower water tank 1 in time, thereby preventing water from overflowing from the table top 2 to the surrounding areas and making the surrounding ground or table top wet and soaked.

[0050] In the embodiment of the present application, the table 2 has a mounting hole 21 that passes through in the height direction, and axial grooves 22 with openings upward are provided on the opposite side edges of the mounting hole 21. The rotating shaft 41 of the flip water receiving tray 4 is placed in the corresponding axial grooves 22. The setting of the axial grooves 22 allows the flip water receiving tray 4 to be directly taken and placed to complete the installation, and the disassembly and assembly are more convenient. The setting of the mounting hole 21 facilitates the setting of two axial grooves 22, so that both sides of the rotating shaft 41 of the flip water receiving tray 4 can play a supporting role, making the structure of the flip water receiving tray 4 stable and the rotating shaft not easily deformed. The left edge of the mounting hole 21 has a platform that presses against the edge of the flip water receiving tray 4. The platform forms a blocking structure, which limits the deflection angle of the flip water receiving tray 4 when it is reset, so that the flip water receiving tray 4 can stop stably after flipping to the pouring position, preventing the flip water receiving tray 4 from deflecting in the opposite direction.

[0051] In the present invention, the flip water receiving tray 4 can also be hingedly installed by the cooperation of the shaft and the hole.

[0052] In this new use model, the lower water tank 1 is barrel-shaped, and the table 2 is snap-fitted to the upper opening of the lower water tank 1, making it convenient for the user to clean and maintain the lower water tank 1 when needed. After the lower water tank 1 is separated, the table 2 can keep the upper water tank 3 in a stable placement state.

[0053] Specifically, the water tank 3 consists of a lower box body 31 and an openable upper cover 32. The mobility of the upper cover 32 provides great convenience in daily maintenance work and cleaning of the lower box body 31, and can prevent dust and bacteria from entering the lower box body 31. The upper cover 32 has a hand-held part 321 for easy operation of the upper cover 32.

[0054] In this application, the water outlet structure 5 can be a common ball valve, needle valve, etc., in order to prevent the pet from causing misoperation of the valve body during use and changing the flow rate, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the water outlet structure 5 includes a water outlet pipe 51 fixedly connected to the upper water tank 3 and a valve core 52 arranged at the water outlet 513 of the water outlet pipe 51. The flow rate is adjusted by adjusting the valve core 52, so that the outflow of water can be accurately controlled according to actual needs, thereby achieving the purpose of saving water and improving water use efficiency.

[0055] The structure of the valve core 52 can be: the water outlet pipe 51 also includes a water inlet 511 connected to the water tank 3, the water inlet 511 is connected to the water outlet 513 through the regulating port 512, the valve core 52 is threadedly connected at the water outlet 513, the conical head or round head of the valve core 52 cooperates with the regulating port 512, and the extension length of the conical head or round head is adjusted by suspending the valve core 52 to adjust the size of the gap between the conical head or round head and the regulating port 512, thereby adjusting the flow rate. The threaded part of the valve core 52 is provided with a guide groove running through the axial direction to allow water to flow out.

[0056] In the present application, the preferred structure of the valve core 52 is that the outlet pipe 51 also includes a water inlet 511 connected to the water tank 3, the water inlet 511 is connected to the water outlet 513 through the regulating port 512, the diameter of the regulating port 512 is smaller than the diameter of the water outlet 513, the valve core 52 includes a coaxially arranged regulating cover 521 and a core shaft 522, the core shaft 522 is coaxially arranged with the regulating cover 521 and is in a through-shape, the internal thread of the regulating cover 521 is threadedly connected to the connector 514 of the outlet pipe 51, and the core shaft 522 is adjusted to the regulating port 513 by rotating the regulating cover 521. 12 is inserted into the inner portion to adjust the size of the water outlet channel between the regulating port 512 and the core shaft 522, thereby realizing the adjustment of the water flow rate according to the demand, the core shaft 522 is clearance-matched with the water outlet 513, wherein the end of the core shaft 522 close to the regulating port 512 is conical or semicircular, and the regulating cover 521 is provided with a drainage hole 523, which will not interfere with the water outlet pipe 51, and the water flowing out of the regulating port 512 enters the water outlet 513, then enters the regulating cover 521 and is discharged along the drainage hole 523, so that the water outlet is smooth.

[0057] In order to avoid misoperation caused by pets when in use, the water outlet structure 5 also includes a protective tube 53 mounted on the water outlet pipe 51. The protective tube 53 is clearance-matched with the adjustment cover 521 to ensure the smoothness of water flow. The valve core 52 is hidden in the protective tube 53, which prevents pets from misoperating and stabilizes the water flow. The protective tube 53 can also play a certain diversion role, so that the length of the water outlet pipe 51 is short and the structure is stable. Among them, the operating end of the core shaft 522 is close to the opening of the protective tube 53, which makes the adjustment operation convenient.

[0058] Example 2 refer to Figures 7 to 9 This embodiment provides a pet water dispenser. Based on the first embodiment, the structures of the upper water tank 3 and the water outlet structure 5 are adjusted to make the water outlet of the water dispenser smoother and at a lower cost.

[0059] like Figure 6 、 Figure 7 and Figure 8 As shown, the upper water tank 3 is composed of three key parts: an outer shell 33 with an open top, an inner box body 31 and an upper cover body 32. Among them, the inner box body 31 is inserted into the outer shell 33 from the top opening. When the inner box body 31 is detachably plugged into other structures, it can be flexibly placed and taken out; a closed cavity for the installation of corresponding devices can be formed between the inner box body 31 and the outer shell 33, so that the corresponding devices can be hidden and the appearance of the body is beautiful; the upper cover body 32 can be opened and tightly covered at the upper opening position of the inner box body 31, and the upper opening of the inner box body 31 is in an open state. This design not only makes it convenient for users to clean and maintain the interior of the inner box body 31, but also makes it convenient to add clean water into the inner box body 31. The use of the upper cover body 32 provides a relatively closed environment for the inside of the water tank.

[0060] In this embodiment, the outer shell 33 is connected to the table 2, and the inner box 31 is placed in the outer shell 33 to realize the installation positioning of the inner box 31. There is no need to reserve an installation position on the inner box 31, so that the inner box 31 is simple to process; in order to enable the inner box 31 to be installed simply and reliably, the upper edge of the inner box 31 is vertically limited by abutting against the upper edge of the outer shell 33, and a limiting boss is provided at the upper edge of the inner box 31 to cooperate with the inner cavity of the outer shell 33 to realize horizontal limitation, so that the inner box 31 can be stably installed without using a locking structure.

[0061] The water outlet structure 5 is the core component of the upper water tank 3 to realize the water outlet function. Specifically, the water outlet structure 5 includes a water outlet pipe 51, an electric valve 54, a connecting water pipe 55, a circuit board 56 and a battery 57. The water outlet pipe 51 is installed on the outer shell 33 and serves as the final discharge channel of the water flow; the electric valve 54 plays an important role in controlling the water flow switch. The electric valve 54 is a common water flow control valve (ball valve or needle valve) on the market. The water supply state is controlled by controlling the working state of the electric valve 54. Its water inlet is connected to the inner box body 31 through the connecting water pipe 55. The water supply port of the inner box body 31 connected to the electric valve 54 is preferably located at the lower part of the inner box body 31 or the water inlet end is set at the water supply port near the bottom of the inner box body 31. The water diversion pipe at the top, when in use, the water in the inner box 31 can be effectively used to the greatest extent, ensuring that the water in the inner box 31 can smoothly enter the electric valve 54; and the water outlet of the electric valve 54 is directly connected to the water outlet pipe 51, so that the water flow controlled by the electric valve 54 can be discharged from the water tank through the water outlet pipe 51; the circuit board 56 serves as the control center of the entire water outlet structure 5, and is electrically connected to the electric valve 54 and the battery 57 respectively, and accurately controls the opening and closing actions of the electric valve 54 by receiving external instructions or built-in programs; the battery 57 provides the necessary power support for the entire water outlet structure 5 to ensure its normal operation.

[0062] To facilitate routine maintenance and replacement of the battery 57, a window 331 is provided on the housing 33 for removing and installing the battery 57. This design allows the user to easily remove and install the battery through the window 331 without having to disassemble the entire water tank when the battery is exhausted or needs to be replaced, greatly improving the convenience of use.

[0063] In addition, a detachable cover 34 is provided at the window 331. The main function of the cover 34 is to seal the window 331 to prevent external dust, moisture and other impurities from entering the water tank, thereby protecting the electrical components inside the water tank from damage. At the same time, a carefully designed avoidance hole 341 is provided on the cover 34. This design has dual practical functions. On the one hand, when the battery 57 needs to be charged, the charging cable can pass smoothly through the avoidance hole 341 and connect to the battery 57 for charging, avoiding the trouble of frequent disassembly and assembly of the cover 34; on the other hand, when the cover 34 needs to be removed for battery 57 replacement or other maintenance operations, the user can also use the avoidance hole 341 to conveniently separate the cover 34 from the window 331, further improving the convenience of operation.

[0064] Since only the electric valve 54 relies on electricity to work in this solution, the power consumption is low and the cost is low.

[0065] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Those skilled in the art will appreciate that various modifications and variations of the present embodiment are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
