Description

Technical Field

[0001] This application relates to the field of drinking device technology, and more specifically to a pet water fountain. Background Technology

[0002] With the increasing popularity of smart homes, especially pet water fountains, pet owners are increasingly favoring them. During the use of pet water fountains, to maintain water quality and safety, UV lamps are typically used to irradiate the entire tank of water for sterilization. However, UV lamps are usually integrated with submersible pumps, making water and electricity separation impossible. This integrated structure hinders disassembly and cleaning, creates blind spots where bacteria can easily grow, and slows down water circulation throughout the tank. Prolonged irradiation is required for thorough sterilization, resulting in low efficiency. Furthermore, the UV light remains on continuously while the pump is running, and leakage can occur if the pump cover is not installed, potentially causing light pollution and harm to humans and pets. This application proposes a new solution to address these issues. Utility Model Content

[0041] In the following detailed disclosure, these embodiments are fully described with reference to the accompanying drawings. In order to enable those skilled in the art to more clearly understand and comprehend the technical solutions of this application, the embodiments described below are not limited thereto. The application will be further described in detail below with reference to the embodiments and the accompanying drawings.

[0042] In this application, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; the term "multiple" refers to two or more unless otherwise expressly defined. The terms "install," "connect," "join," and "fix" should be interpreted broadly. For example, "connect" can mean a fixed connection, a detachable connection, or an integral connection; "join" can mean a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0044] This application provides a pet water dispenser, including a base assembly 2 and a water tank assembly 1. The base assembly 2 includes a sterilization section 3. The water tank assembly 1 is disposed on the base assembly 2 and includes a water storage section 11 and a water delivery section 12. The water storage section 11 is connected to the water delivery section 12. The water delivery section 12 is provided with a light blocking structure 4 that blocks the sterilization section 3.

[0045] The pet water fountain provided in this embodiment physically isolates the sterilization part 3 from the water storage part 11 by placing the sterilization part 3 on the base assembly 2. There is no direct electrical connection between the sterilization part 3 and the water tank assembly 1. The physical separation structure isolates the live parts from the water contact parts, reducing the possibility of the electrical system coming into contact with the water. The separation of water and electricity reduces the risk of leakage and also helps to improve the service life of the pet water fountain.

[0046] The pet water dispenser provided in this embodiment, such as Figure 1 As shown, the water tank assembly 1 can be detached from the base for cleaning, and the water storage section 11 can be independently disassembled for cleaning and maintenance. The electronic components inside the base assembly 2 are kept in a dry environment. The detachable design makes it easy for users to clean the water storage section 11, eliminating hidden areas that are difficult to clean in traditional one-piece structures.

[0047] The pet water dispenser provided in this embodiment emits sterilization light from the sterilization unit 3 and projects it onto the water delivery unit 12 to form a concentrated sterilization area. The light energy is concentrated on the dynamic water flow in the water delivery unit 12, increasing the light intensity per unit volume of water. After the water flows through the water delivery unit 12 for sterilization, part of it flows back to form multiple cycles of treatment, forming multiple rounds of sterilization process, which strengthens the sterilization coverage, shortens the sterilization time, and improves sterilization efficiency and effect.

[0048] The pet water dispenser provided in this embodiment has an opaque outer shell for the water delivery section 12, and a light-blocking structure 4 is provided in the water delivery section 12. The propagation path of the sterilization light in the water delivery section 12 is limited by the light-blocking structure 4. While maintaining the water flow, an optically enclosed space is established, which reduces the risk of the sterilization light directly or indirectly irradiating the user or pet, reduces light pollution to the surrounding environment, reduces the possibility of diffusion to the outside of the pet water dispenser, and improves safety.

[0049] In one possible implementation, such as Figure 2 and Figure 3As shown, the sterilization unit 3 includes a sterilization lamp 31 and a first light-transmitting element 32. The water tank assembly 1 is provided with a second light-transmitting element 33 at a position corresponding to the first light-transmitting element 32. The light emitted by the sterilization lamp 31 passes through the first light-transmitting element 32 and the second light-transmitting element 33 and faces the light-blocking structure 4.

[0050] Among them, such as Figure 2 As shown, at least a portion of the water delivery section 12 is inserted into the water storage section 11. The water delivery section 12 is connected to the water storage section 11, and water in the water storage section 11 can be drawn into the water delivery section 12, so that water in the water storage section 11 can be delivered to the water bowl 124 for pet drinking through the water delivery section 12. Figure 8 as well as Figures 13-15 As shown, the irradiation direction of the sterilizing lamp 31 is towards the inside of the water supply section 12. The sterilizing light emitted by the sterilizing section 3 is projected into the water supply section 12 to form a concentrated sterilization area. The light energy is concentrated on the dynamic water flow that circulates multiple times in the supply section, which improves the sterilization efficiency and sterilization effect. The light blocking structure 4 is located on the propagation path of the sterilizing light to block it and prevent the sterilizing light from spreading outside the pet water dispenser, so as to avoid damaging the eyesight of people or pets.

[0051] Furthermore, the germicidal lamp 31 is a UV lamp. In the pet water dispenser, the UV lamp emits ultraviolet light of a specific wavelength to destroy the genetic material structure of microorganisms, blocking their reproductive ability and thus inhibiting the potential risk of biological contamination in the water supply section 12. The dynamic water flow is repeatedly exposed to ultraviolet radiation during circulation, which can continuously act on the flowing microorganisms, reducing their attachment and aggregation within the pipes. For flowing water, ultraviolet light can cover a larger contact area, improving sterilization efficiency. During long-term operation, the ultraviolet treatment and water circulation work synergistically, reducing the survival probability of microorganisms in a closed system, helping to maintain the biological safety of the water quality in the drinking tray 124, and reducing problems such as odor or sedimentation caused by microbial growth.

[0052] The germicidal light propagation path is provided with multiple layers of light-transmitting media, including a first light-transmitting element 32 fixed to the top of the base assembly 2 and a second light-transmitting element 33 fixed to the bottom of the water storage part 11. The germicidal lamp 31 is set inside the base assembly 2. The water and electricity are physically isolated by the double light-transmitting elements, which improves the safety of the equipment. It also has a focused light path and anti-fouling effect, which facilitates frequent cleaning of the water tank assembly 1 and takes into account both pet health and user experience.

[0053] The first light-transmitting element 32 is embedded in the top of the base assembly 2 and aligned with the germicidal lamp 31. The second light-transmitting element 33 is embedded in the bottom of the water storage part 11 and is coaxially designed with the first light-transmitting element 32. When the water storage part 11 is installed in place, the distance between the two light-transmitting elements is controlled within the effective radiation range of the germicidal light. The edges of the light-transmitting elements can be pressed tightly by the silicone sealing ring to achieve waterproof and dustproof protection.

[0054] A closed light channel is formed between the first light-transmitting element 32 and the second light-transmitting element 33. The water inside the water storage part 11 only contacts the outer surface of the second light-transmitting element 33 and does not seep into the base assembly 2.

[0055] Understandably, a hydrophobic and anti-fouling coating can also be applied to the surface of the second light-transmitting element 33 to reduce scale adhesion.

[0056] Understandably, the first light-transmitting element 32 and the second light-transmitting element 33 can be made of materials such as quartz glass or high-transmittance UV resin, and the surface can also be coated with an anti-reflection film to reduce the loss of sterilization light reflection.

[0057] In one possible implementation, such as Figures 2-5 As shown, the light blocking structure 4 includes a light blocking member 41 and a connecting arm 42. The light blocking member 41 is connected to the inner wall of the water conveying part 12 through the connecting arm 42. A flow channel is formed between the light blocking member 41 and the inner wall of the water conveying part 12. The cross-sectional area of ​​the flow channel is S1, and the cross-sectional area of ​​the light blocking member 41 is S2, wherein 0.6≤S1 / S2≤1.5.

[0058] Among them, such as Figure 12 As shown, the light-shielding member 41 is connected to the inner wall of the water conveying section 12 via the connecting arm 42. The light-shielding member 41 can provide a suitable radiation coverage for the sterilization light by limiting the propagation path of the sterilization light, and can also reduce light scattering or energy loss by moderately blocking the light. A roughly annular flow channel can be formed between the light-shielding member 41 and the water conveying section 12 to guide the water flow to flow smoothly in a specific direction. The gap layout between the light-shielding member 41 and the water conveying section 12 can maintain the continuity of the water flow cross section and enhance the effective utilization rate of radiation energy, so that the water flow and sterilization process can remain stable.

[0059] Understandable, such as Figure 11 As shown, the flow channel of the water conveying section 12 can be circular or nearly circular, and the vertical projection surface of the light-shielding member can also be circular or nearly circular. For example... Figure 12 As shown, assuming the inner diameter of the water conveying section 12 is D1 and the diameter of the vertical projection surface of the light-shielding member 41 is D2, that is, the outer diameter of the flow channel is D1 and the inner diameter is D2, the cross-sectional area of ​​the flow channel and the cross-sectional area of ​​the light-shielding member 41 are in the range of S1 / S2, which is 0.6-1.5. This ratio range helps to balance the structural relationship between the flow channel and the light-shielding member 41, so that the water flow in the water conveying section 12 maintains a stable and uniform flow state, reduces the influence of the light-shielding member 41 on the water flow in the water conveying section 12, and the resistance of the water flow through the annular area and the guiding effect of the light-shielding member 41 on the flow path tend to be coordinated, reducing the eddies or energy loss caused by the abrupt change in cross-section of the water flow.

[0060] Furthermore, the ratio of the cross-sectional area of ​​the flow channel to the cross-sectional area of ​​the light-shielding member 41, S1 / S2, ranges from 0.8 to 1.2. When the area ratios of the two are close, the resistance of water flow through the annular area and the guiding effect of the light-shielding member 41 on the flow path are more coordinated. The structure is more compact under this ratio, optimizing the fluid dynamics characteristics in a limited space and improving the synergistic efficiency of water flow and bactericidal light effect.

[0061] In one possible implementation, such as Figure 2 As shown, the water conveying section 12 is provided with a water inlet 1234. Water from the water storage section 11 enters the water conveying section 12 through the water inlet 1234. The light blocking structure 4 is located downstream of the water inlet 1234, and there is a height difference of at least 1 mm between the light blocking structure 4 and the upper edge of the water inlet 1234.

[0062] Along the axial direction of the water conveying section 12, the height difference between the light-blocking structure 4 and the inlet 1234 is H, where H ≥ 1 mm. By adjusting the spatial arrangement between the light-blocking structure 4 and the inlet 1234, the water flow is guided to form a smooth transition as it enters the water conveying section 12 through the inlet 1234, reducing the direct impact of the water flow on the downstream light-blocking structure 4. When the water flows out of the inlet 1234, the at least 1 mm height difference provides a buffer zone for the flow direction, reducing local eddies or disturbances caused by sudden velocity changes. This allows the water flow to diffuse naturally before contacting the light-blocking structure 4, forming a more uniform flow distribution, weakening the impact force of the water flow, and reducing the frictional loss of turbulence on the surface of the light-blocking structure 4 and the pipe wall. This improves the stability of the flow state, reduces abnormal noise or vibration, and prevents local low pressure from interfering with the water conveying efficiency.

[0063] Furthermore, the height difference H between the light-blocking structure 4 and the inlet 1234 is ≥5mm. Appropriately increasing the height difference can provide more space for water flow to diffuse, prompting the water flow to readjust its velocity distribution before contacting the light-blocking structure 4, reducing flow separation or energy loss, making the axial acceleration or deceleration process of the water flow smoother, and gradually balancing the inertial force in the flow direction with the frictional resistance of the pipe wall, which is conducive to forming a stable water flow state.

[0064] In one possible implementation, such as Figure 2 and Figure 13 As shown, the light-blocking structure 4 includes a streamlined structure for guiding water flow to the flow channel.

[0065] Among them, the streamlined frontal surface of the light-blocking structure 4 guides the water flow to turn smoothly along the preset path by conforming to the natural movement trend of the fluid, reducing abrupt changes in the flow direction. When the water flow comes into contact with the frontal surface of the light-blocking structure 4, it gradually changes its trajectory and forms a continuous flow state in the flow channel.

[0066] Among them, such as Figure 2 and Figure 13 As shown, the curved profile of the streamlined structure is adapted to the direction of water flow, which helps the water flow to maintain continuity during the turning process. The coordinated design of the curved surface of the streamlined structure and the direction of water flow can form a dynamic scouring effect, which removes particles or biofilms that may be attached to the surface of the light-blocking structure 4 by means of fluid shear force.

[0067] When the light blocking structure 4 includes a light blocking member 41 disposed in the water conveying section 12, the light blocking member 41 can be coaxially disposed with the water conveying section 12, and an annular flow channel is formed between the two, which enables the streamlined front surface of the water flow to contact the light blocking member 41 to be evenly distributed along the circumferential direction, and the symmetrical flow characteristics reduce the tendency of the water flow to impact the pipe wall on one side.

[0068] It is understandable that streamlined structures include hemispherical surfaces, conical surfaces, convex arc surfaces, etc. Water flow is evenly dispersed along the streamlined structure, reducing impact pressure, and the curvature transition is used to adjust the direction of water flow and balance the velocity distribution.

[0069] Furthermore, the side of the light-shielding member 41 and the connecting arm 42 near the sterilization section 3 can be designed as a smooth arc surface, with the flow-facing surface protruding in the direction of the inflow. The protruding arc surface of the flow-facing surface follows the direction of water flow, and the protruding arc surface guides the water flow to flow close to the surface, reducing turbulence caused by direct impact.

[0070] In one possible implementation, such as Figure 8 As shown, the water conveying section 12 has a minimum inner diameter section. The minimum inner diameter section of the water conveying section 12 is located on the side of the light blocking structure 4 away from the sterilization section 3. The vertical upward projection of the light blocking structure 4 completely blocks the minimum inner diameter section of the water conveying section 12.

[0071] The inner wall of the water conveying section 12 converges inward on the side away from the water inlet 1234. The water conveying section 12 includes a water conveying cavity 101. The water conveying cavity 101 has a minimum inner diameter section in the axial direction. The vertical upward projection of the light blocking structure 4 completely blocks the minimum inner diameter section of the water conveying section 12. The minimum flow area of ​​the water conveying cavity 101 is located in the projection area of ​​the light blocking member 41, which is used to block the sterilization light in the flow channel.

[0072] In this section, the inner wall of the water conveying section 12 gradually converges towards the axial direction on the side away from the water inlet 1234, forming a tapered section, and finally forming the minimum inner diameter section in the axial direction. This section has the smallest cross-sectional area, and the water flow is accelerated due to the change in cross-sectional area. The projection of the light blocking structure 4 along the axial direction completely covers the cross-section of the minimum inner diameter section. At least part of the sterilization light is blocked by the light blocking structure 4. The sterilization light in the flow channel is effectively blocked in the minimum inner diameter section. The projection of the light blocking structure 4 and the minimum inner diameter section achieve the matching of the light path and the flow path.

[0073] In one possible implementation, such as Figures 2-5As shown, the water conveying part 12 also includes a water nozzle 122, which includes a water outlet cavity 104. The water outlet cavity 104 has a minimum inner diameter section, and the vertical upward projection of the light blocking structure 4 completely blocks the minimum inner diameter section of the water outlet cavity 104.

[0074] When the water conveying section 12 also includes a water nozzle 122, the minimum inner diameter section is located on the water nozzle 122. The inner diameter of the minimum inner diameter section of the water nozzle 122 is smaller than the inner diameter of the water conveying section 12. The vertical upward projection of the light blocking structure 4 completely blocks the minimum inner diameter section of the water cavity 104. The light blocking structure 4 and the water nozzle 122 work together to block the sterilization light inside the water conveying section 12.

[0075] Among them, such as Figure 5 As shown, this embodiment provides a specific structure of a water tap 122. The water tap 122 includes an inner tube 1221, a locking tube 1222, and a locking cavity 1223. The locking tube 1222 is disposed on the outer periphery of the inner tube 1221 and surrounds the inner tube 1221 to form the locking cavity 1223, which is used to lock onto the end of the water supply pipe 121. At least part of the inner tube 1221 is located inside the water supply pipe 121 to block the sterilization light in the flow channel.

[0076] The inner tube 1221 serves as the core flow channel, with a portion of it embedded inside the water supply section 12. The locking tube 1222 is coaxially positioned around the outer periphery of the inner tube 1221, forming an annular locking cavity 1223 between them. The cross-sectional shape of the locking cavity 1223 can be triangular, trapezoidal, dovetail, etc., matching the contour of the outer wall of the water supply pipe end, and achieving rapid assembly through elastic deformation or a snap-fit ​​structure.

[0077] The embedded tube 1221 has both light-shielding and flow-guiding functions. The embedded tube 1221 is made of opaque material. The part of it that extends into the water supply pipe extends along the axial direction and covers the cross-section of the flow channel, forming a physical shield against the sterilization light. The embedded tube 1221 has a minimum inner diameter section. This section has the smallest cross-sectional area and the flow velocity reaches its peak. The water flow is accelerated due to the change in cross-sectional area, which increases the water outlet speed of the faucet 122.

[0078] In one possible implementation, such as Figure 13 As shown, the light blocking structure 4 includes a first light blocking element 411 and a second light blocking element 412. The water supply section 12 includes a water supply pipe 121 and a water nozzle 122. The first light blocking element 411 and the second light blocking element 412 are arranged alternately along the axis of the water supply pipe 121 and / or the water nozzle 122 to block the light in the water supply section 12.

[0079] The first light-shielding element 411 and the second light-shielding element 412 are arranged alternately along the axis of the water supply pipe 121 and / or the water nozzle 122 to form an alternating shading area. Through spatial complementarity, the sterilization light is blocked multiple times, reducing the possibility of diffusion to the outside of the pet water dispenser and improving safety.

[0080] Furthermore, the first light-shielding element 411 is disposed on the side near the water inlet 1234, and the second light-shielding element 412 is disposed on the side of the first light-shielding element 411 away from the water inlet 1234. The first light-shielding element 411 and the second light-shielding element 412 include streamlined frontal surfaces.

[0081] The water supply pipe 121 and the water nozzle 122 can be coaxially arranged. The first light-shielding element 411 and the second light-shielding element 412, which are arranged in an alternating manner, form an asymmetric flow channel on both sides of the axis of the water supply pipe 121 and / or the water nozzle 122. The streamlined frontal surface follows the direction of water flow, guides the fluid to turn smoothly along the curved surface, reduces the kinetic energy loss caused by the sudden change in flow direction, reduces the direct impact intensity on the surface of the light-shielding element, and suppresses the generation of turbulence.

[0082] In one possible implementation, such as Figure 14 As shown, the optical axis of the germicidal light emitted by the germicidal lamp 31 is set at an angle to the axis of the water supply section 12. The pipe wall of the water supply section 12 forms a light blocking structure 4 in the direction of the extension of the germicidal light, which is used to block the germicidal light to prevent the germicidal light from leaking outward.

[0083] The optical axis of the germicidal lamp 31 forms a non-zero angle with the axis of the water conveying section 12. The specific range of the angle can be designed according to the height of the water conveying section 12. The germicidal light enters the water flow in the water conveying section 12 at an inclined angle and is blocked by the opaque pipe wall of the water conveying section 12.

[0084] In one possible implementation, such as Figure 8 and Figure 13 As shown, the light axis of the germicidal lamp 31 is set along the axis of the water supply pipe 121, and the light emission angle of the germicidal lamp 31 is α, where 20°≤α≤40°.

[0085] Among them, the optical axis of the germicidal light emitted by the germicidal lamp 31 is basically coincident with the axis of the water conveying section 12. The front end of the lamp body is equipped with a parabolic reflector cup or Fresnel lens to constrain the diffused light into a narrow beam of 20° to 40°. The narrow beam penetrates into the core of the water flow along the axis of the water conveying section 12 and acts directly on the dense area of ​​microorganisms, overcoming the problem of edge attenuation of the wide-angle light path, forming a high-density irradiation area, reducing light energy loss, significantly improving the germicidal light intensity per unit area, and improving the sterilization efficiency.

[0086] Understandably, the light emission angle of the germicidal lamp 31 can be designed based on the axial distance between the germicidal lamp 31 and the light-shielding member 41. The width of the light-shielding member 41 increases as the axial distance between the back surface of the light-shielding member 41 and the germicidal lamp 31 increases. The axial distance between the back surface of the light-shielding member 41 and the germicidal lamp 31 is the shielding height h. When the shielding height remains constant, the width of the light-shielding member 41 increases as the light emission angle of the germicidal lamp 31 increases; when the light emission angle of the germicidal lamp 31 remains constant, the width of the light-shielding member 41 increases as the shielding height increases.

[0087] The light-shielding component 41 can cover the entire light-emitting area of ​​the germicidal lamp 31, and is used to block all germicidal light in the light-emitting area. A germicidal area is formed between the light-shielding component 41 and the germicidal lamp 31, and the germicidal light is blocked by the light-shielding component 41.

[0088] Among them, such as Figure 8 As shown, the light-shielding component 41 can also cover part of the light-emitting area of ​​the germicidal lamp 31, which is used to block part of the germicidal light in the light-emitting area. The other part of the germicidal light passes through the flow channel, forming a germicidal area between the light-shielding component 41 and the germicidal lamp 31 and in the flow channel, thereby increasing the germicidal area and further improving the germicidal effect. Subsequently, the germicidal light in the flow channel can be blocked by the opaque water nozzle 122 or by reducing the inner diameter of the water supply pipe 121.

[0089] In one possible implementation, such as Figure 1 As shown, the water tank assembly 1 is detachably connected to the base assembly 2, the water storage part 11 is detachable from the base assembly 2, and the water delivery part 12 is detachably connected to the water storage part 11.

[0090] Among them, such as Figure 1 and Figure 9 As shown, the water tank assembly 1 is detachably connected to the base assembly 2 via snap-fit, magnetic attraction, or interface. The water tank assembly 1 and the base assembly 2 are relatively independent. The base assembly 2 integrates a water pump assembly 111, a sterilization unit 3, a circuit control module, and other electrical components. The water tank assembly 1 is used for water storage and transportation, and the water circuit and electrical circuit are physically isolated. For disassembly, simply lift the water tank assembly 1 upwards to separate it from the base assembly 2. The electrical components are encapsulated in a waterproof shell within the base assembly 2 to prevent contact with water and reduce the risk of electric leakage. This allows for easy direct movement of the water storage unit 11 for water intake or cleaning operations, making it more convenient to use.

[0091] Among them, such as Figure 1 and Figure 10 As shown, the water supply unit 12 is connected to the water storage unit 11 via a plug-in interface or quick-release connector. The water supply unit 12 can be disassembled independently to facilitate flushing of internal pipes or replacement of filter elements. The water supply unit 12 can be replaced or repaired separately without replacing the entire equipment, thus reducing maintenance costs.

[0092] In one possible implementation, such as Figure 7 and Figure 9 As shown, the pet water fountain includes a sensor control component 5. The conditions for the sensor control component 5 to send a sterilization command to the sterilization unit 3 include: the water supply unit 12 and the water storage unit 11 being in the installed position.

[0093] When the water supply unit 12 and the water storage unit 11 are installed, the sensing control component 5 determines whether the water supply unit 12 and the water storage unit 11 are in place. When the installation signal is received, the processor sends a start command to the sterilization unit 3. When disassembling, the water supply unit 12 moves away from the base component 2, causing the signal to be interrupted, and the processor cuts off the power supply to the sterilization unit 3.

[0094] The pet water dispenser provided in this embodiment uses the physical installation state as the condition for sterilization activation, eliminating the need for manual operation of the switch, simplifying the operation process. The sterilization function only runs after assembly, reducing energy consumption. It automatically stops when disassembling and cleaning, reducing the risk of users forgetting to turn off the power and reducing the risk of sterilization light leakage when the water supply section 12 is not assembled, thus improving the safety of users and pets.

[0095] This embodiment provides a specific composition of the sensing control component 5, such as... Figure 7 and Figure 9 As shown, the sensing control component 5 includes a magnet 51 and a Hall element 52 disposed opposite to each other. The magnet 51 is disposed on the water supply section 12, and the Hall element 52 is disposed on the base assembly 2.

[0096] In this design, magnet 51 is embedded in the water supply section 12 for connection to the water storage section 11, and Hall element 52 is integrated into the corresponding position on the base assembly 2. When the water supply section 12 and the water storage section 11 are installed in place, magnet 51 and Hall element 52 are precisely aligned in the axial direction, and the distance between them is controlled within the effective sensing range. Hall element 52 does not require direct power supply and works by relying on the magnetic field change of magnet 51, reducing circuit complexity and energy consumption. Magnet 51 has strong corrosion resistance and can be used for a long time in humid environments.

[0097] When the water supply unit 12 and the water storage unit 11 are installed, the magnet 51 approaches the Hall element 52, and the Hall element 52 outputs a high / low level signal to the control processor. The processor determines whether the installation is complete by checking the level status. If the signal remains stable for more than a set time threshold, the installation is considered complete. When the installation is complete signal is received, the processor sends a start command to the sterilizing lamp 31. When disassembling, the magnet 51 moves away from the Hall element 52, causing the signal to be interrupted. The processor then cuts off the power to the sterilizing unit 3 and enters standby mode.

[0098] Understandably, the installation signal can simultaneously activate the power supply circuit of the water pump component 111 within the base component 2, ensuring that the water circuit connectivity is synchronized with the start and stop of the circuit, further enhancing the safety of water and electricity separation.

[0099] In one possible implementation, such as Figure 2 and Figure 3 As shown, the water storage section 11 includes a water storage chamber 103, and the pet water drinker includes a water pump assembly 111. The water pump assembly 111 includes an impeller 1111 and a drive component 1112, which is used to transport water in the water storage chamber 103 through the water outlet to the water delivery chamber 101 of the water delivery pipe 121.

[0100] Among them, such as Figure 9 and Figure 10 As shown, the drive component 1112 is disposed inside the base assembly 2, and the impeller 1111 is disposed at the bottom of the water storage part 11 and aligned with the drive component 1112. When the water storage part 11 is assembled on the base assembly 2, the drive component 1112 is poweredly connected to the impeller 1111 to drive the impeller 1111 to rotate.

[0101] The impeller 1111 is rotatably disposed in the water storage section 11. The impeller 1111 may include multiple blades. When the impeller 1111 rotates, the blades do work on the water flow, transferring rotational kinetic energy to the water flow, increasing the speed and pressure of the water flow, thereby lifting the water through the water pipe 121 to the drinking basin 124.

[0102] The water storage section 11 is designed to be open, allowing users to clean the impeller 1111 at the same time as cleaning the water storage section 11. The impeller 1111 can also be detached from the water storage section 11, allowing users to remove the impeller 1111 for separate cleaning, reducing the creation of unsanitary areas and improving the cleanliness of drinking water.

[0103] like Figure 9 As shown, the base assembly 2 has an inwardly recessed first mounting portion 21, and the driving component 1112 is disposed within the first mounting portion 21, as shown. Figure 10 As shown, the bottom of the water storage section 11 includes a second assembly section 112 that protrudes outward, the impeller 1111 is disposed in the second assembly section 112, the second assembly section 112 is installed in conjunction with the first assembly section 21, and the water delivery section 12 is installed in conjunction with the second assembly section 112.

[0104] The first assembly part 21 of the base assembly 2 is designed as a groove, in which the drive component 1112 is fixed. The second assembly part 112 of the water storage part 11 is a corresponding structure that protrudes outward, is embedded in the impeller 1111 and nested with the first assembly part 21. The matching of the concave and convex shapes facilitates the alignment of the drive component 1112 with the shaft of the impeller 1111.

[0105] By integrating the impeller 1111 and the water delivery section 12 into the second assembly section 112, the space utilization inside the water tank assembly 1 is optimized, resulting in a more compact and efficient water flow path. A portion of the water delivery section 12 extends into the second assembly section 112, which also reduces the overall height of the pet water fountain.

[0106] like Figure 2 and Figure 7 As shown, the water conveying section 12 includes a suction chamber 105 for accommodating the water pump assembly 111. The suction chamber 105 is connected to the water conveying chamber 101 through the water inlet 1234 and is connected to the return water chamber 102. The water pump assembly 111 is used to convey water in the water storage chamber 103 and / or the return water chamber 102 sequentially through the suction chamber 105, the water conveying chamber 101 and the water outlet chamber 104 to the drinking water tray 124.

[0107] The suction chamber 105 is located at the bottom of the water conveying section 12, and the water pump assembly 111 is fixed inside. The suction chamber 105 is connected to the return chamber 102 and the water conveying chamber 101 respectively. When the impeller 1111 rotates, a negative pressure is generated in the suction chamber 105. The water in the return chamber 102 is drawn into the suction chamber 105 under the action of the negative pressure. After being accelerated and guided by the impeller 1111, the water flows from the suction chamber 105 into the water conveying chamber 101 through the water inlet 1234, and then into the drinking water tray 124 through the water conveying chamber 101, thereby realizing the rapid circulation and filtration of drinking water in the drinking water tray 124.

[0108] The system prioritizes pumping water back to the water storage chamber 102 to reduce the frequency of water replenishment in the water storage chamber 103 and lower the frequency of water changes. Combined with the filter layer 1232 and ultraviolet sterilization, it maintains water quality cleanliness to prevent pets from drinking stale water.

[0109] In one possible implementation, such as Figures 2-4 As shown, the water supply unit 12 also includes a return water pipe 123 and a drinking water tray 124. The drinking water tray 124 is used to hold drinking water. A return water hole 1241 is provided on the drinking water tray 124. The return water hole 1241 and the bottom of the drinking water tray 124 have a height difference, which is used to transport water in the drinking water tray 124 that exceeds the preset liquid level to the water storage unit 11 and / or the return water pipe 123.

[0110] Among them, such as Figure 2 and Figure 4 As shown, at least one return water hole 1241 is provided on the drinking water tray 124. The height of the hole is lower than the edge of the drinking water tray 124 but higher than the bottom, forming a preset liquid level threshold. When the water level of the drinking water tray 124 exceeds the height of the hole, the excess water flows naturally into the return water pipe 123 and / or the water storage part 11 through the return water hole 1241, and the liquid level automatically stabilizes within a safe range.

[0111] The pet water dispenser provided in this embodiment includes a return pipe 123, such as... Figure 2As shown, the return water hole 1241 can be directly set above the return water pipe 123. The residual water flows naturally into the return water pipe 123 through the return water hole 1241. The water pump assembly 111 will transport the filtered water from the return water chamber 102 to the water delivery chamber 101 and flow into the drinking water tray 124 to form a continuous cycle, thereby repeatedly circulating and filtering the water in the drinking water tray 124 to improve the cleanliness of the drinking water.

[0112] It is understandable that drinking water circulates, is filtered, and sterilized within the drinking tray 124 and the water delivery section 12. Compared to related technologies, which require water flowing from the drinking tray 124 and filtered directly into the water storage section 11, and then drawing water from the water storage section 11 for overall circulation filtration, this embodiment of the application forms a local circulation water path between the drinking tray 124, the filter layer 1232, and the water delivery section 12. This reduces the scope of circulation filtration and significantly decreases the flow rate of the circulating water, thereby significantly improving filtration efficiency and effect. Furthermore, sterilization is achieved through sterilization light in the circulation water path of the water delivery section 12, significantly improving sterilization effect and efficiency.

[0113] In addition, the drinking water flowing from the drinking tray 124 is filtered and does not flow directly back to the water storage section 11, which can reduce the risk of contamination of the clean water source due to the low cleanliness of the water after one filtration and reduce the risk of water quality degradation of the entire tank of clean water source.

[0114] In one possible implementation, such as Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the return water pipe 123 includes a return water chamber 102, and the water supply chamber 101 is connected to the return water chamber 102. The return water pipe 123 is provided with a water inlet hole 1233, which is connected to the return water chamber 102 and the water storage chamber 103 respectively. A filter layer 1232 is provided in the return water plate 1231 at the top of the return water pipe 123 and is located below the return water hole 1241.

[0115] The return water chamber 102 is connected to the water chamber through the water inlet hole to realize the dual water source mode. The return water chamber 102 circulates water and the water storage chamber 103 is replenished. When the water pump assembly 111 is started, it first draws water stored in the return water chamber 102. When the water level in the return water chamber 102 is insufficient, the water storage chamber 103 is automatically replenished, forming a circulation path of "return water chamber 102 → suction chamber 105 → water delivery chamber 101 → water outlet chamber 104 → drinking water tray 124". This reduces the consumption of the water storage chamber 103 and increases the water circulation state in the water delivery chamber 101. The sterilization light treatment and water circulation work together to improve the sterilization efficiency.

[0116] Among them, such as Figure 5As shown, the return water pipe 123 includes a filter layer 1232 for filtering the water flowing out of the drinking tray 124. The filtered water will flow into the return water chamber 102. The filter layer 1232 may include filter cotton, filter screen, filter cartridge, etc., which have filtering properties.

[0117] The filter layer 1232 can be set in the drinking water tray 124 or the return water tray 1231. As long as the filter layer 1232 is located between the return water hole 1241 and the return water chamber 102 of the drinking water tray 124, the polluted water flowing out of the drinking water tray 124 can be filtered.

[0118] In one possible implementation, such as Figure 15 As shown, the outer casing of the water supply unit 12 is opaque. The water supply unit 12 includes a return water pipe 123. The return water pipe 123 is provided with a third light-transmitting element 1235. The light emitted by the germicidal lamp 31 enters the return water pipe 123 through the third light-transmitting element 1235.

[0119] The outer shell of the water supply section 12 is made of opaque material, and the interior is divided into independent chambers. The water supply pipe 121 and the return water pipe 123 are arranged in parallel, with an isolation wall between them. A third light-transmitting element 1235 is installed on the isolation wall. The germicidal lamp 31 is fixed in the base assembly 2. The germicidal light is projected onto the return water chamber 102 through the first light-transmitting element 32, the second light-transmitting element 33, and the third light-transmitting element 1235 in sequence, sterilizing the water flow in the return water chamber 102 and simultaneously killing microorganisms attached to the surface of the return water chamber 102. This increases the irradiation time of the water flow, further improving the sterilization effect and efficiency, and improving the cleanliness of drinking water. At the same time, it can also be projected onto the filter layer 1232 to simultaneously kill microorganisms attached to the surface of the filter material. Due to the obstruction of the opaque filter layer 1232, the germicidal light is prevented from leaking outward.

[0120] Understandably, the third light-transmitting component 1235 can be made of materials such as quartz glass with high UV transmittance or UV resin with high light transmittance, and the edges are fixed with silicone sealing rings to achieve water channel sealing.
