Description

Technical Field

[0001] This utility model relates to the field of pet water dispenser technology, and more specifically, to a pet water dispenser. Background Technology

[0002] As people's living standards continue to improve, more and more families are keeping pets. However, due to school or work commitments, many families are unable to properly care for their pets during this time. Pet water fountains, as intelligent drinking water products, can provide pets with drinking water at set times and in measured quantities, offering great convenience to pet owners.

[0003] In some situations, such as when the owner is away on a long business trip and the pet is left alone at home, the drinking water in the water trough is not changed in a timely manner, and the unfinished water remains stagnant for a long time, which can easily breed bacteria.

[0004] However, the relevant technology has at least one of the following problems: the existing pet water fountains have a simple structure, and the water tank can only be used to collect drinking water. If the drinking water in the tank is left to stand for a long time, bacteria can easily grow, which will affect the pet's health. Utility Model Content

[0005] The technical problem solved by this invention is that the existing pet water fountains have a simple structure, and the water tank can only be used to collect drinking water. If the drinking water in the tank is left to stand for a long time, bacteria can easily grow, thus affecting the pet's health.

[0006] To solve the above problems, this utility model provides a pet water fountain, including: a main body; a drinking part disposed on the upper part of the main body, and the upper end of the drinking part having a cavity for holding a target liquid; and a water stirring device installed on the main body, with the movable end of the water stirring device extending into the interior of the cavity for stirring the target liquid contained therein.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution generates water flow disturbance through mechanical agitation deep inside the liquid, ensuring that the liquid in the entire cavity is in motion. This active agitation mechanism significantly improves water flow, making it impossible for bacteria to adhere to the inner surface of the drinking part, thereby inhibiting bacterial growth.

[0008] In one embodiment of this utility model, the water stirring device includes: a water stirring plate, which is disposed in the cavity and on one side near the bottom surface of the drinking part; and a driving mechanism, which is connected to the water stirring plate to drive the water stirring plate to rotate in a first plane; wherein the first plane is parallel to the bottom surface.

[0009] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution uses a horizontally rotating agitator to directly act on the water at the bottom, forming a circulating flow covering the entire cross-section of the container and eliminating dead zones in the water flow. In existing technologies, mechanical transmission components are prone to wear or corrosion due to long-term immersion. This solution uses non-contact magnetic drive, which reduces maintenance costs and avoids water pollution.

[0010] In one embodiment of this utility model, the main body includes a base, which is located at the lower end of the drinking part; the driving mechanism includes: a first magnet group, which is fixedly disposed on the upper side of the stirring plate; a drive motor, which is mounted on the base, with the drive shaft of the drive motor close to the side of the drinking part and perpendicular to the first plane; and a second magnet group, which is connected to the drive shaft; wherein the second magnet group is coupled to the first magnet group.

[0011] Compared to existing technologies, this solution offers the following advantages: Traditional pet water fountains use a structure where the motor is directly connected to the stirring blades, requiring a shaft hole at the bottom of the water tank and a waterproof sealing ring. Over time, this can lead to aging of the sealing ring and leakage. This solution, however, utilizes magnetic coupling transmission, enabling non-contact power transmission between the drive mechanism and the water treatment components, completely eliminating the risk of liquid leakage. Existing magnetic actuators with a transverse magnetic pole layout suffer from low torque transmission efficiency. This solution, through a vertical axial magnetic pole arrangement, concentrates the magnetic lines of force along the drive shaft, significantly improving torque transmission efficiency.

[0012] In one embodiment of this utility model, the driving mechanism further includes: a magnet mounting base, which is fixedly sleeved on the driving shaft to enable the magnet mounting base to rotate along the second plane; wherein the second plane is parallel to the first plane, and the second magnet assembly is fixedly disposed on the magnet mounting base.

[0013] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: By adding a magnet mounting base with planar constraints, the movement trajectory of the second magnet group is restricted to a parallel plane. At the same time, the interference fit is used to eliminate assembly gaps, thus avoiding the problem of magnetic transmission instability.

[0014] In one embodiment of this utility model, the second magnet assembly and the magnet mounting base are detachably connected.

[0015] Compared to existing technologies, the technical advantages of this solution are as follows: Traditional pet water fountains typically weld or bond the magnet assembly to the drive mechanism, requiring the entire drive unit to be replaced during maintenance, which is complex and costly. This solution, however, uses a detachable connection structure, allowing the second magnet assembly to be replaced separately, significantly simplifying the maintenance process and reducing operating costs.

[0016] In one embodiment of this utility model, the upper end of the water stirring plate is provided with at least one mounting groove, and the first magnet group is fixedly installed in the mounting groove.

[0017] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution achieves the fixation of the magnet assembly without the need for additional fixing components by mechanically limiting the mounting slot.

[0018] In one embodiment of this utility model, the upper end of the water stirring plate is provided with a first mounting groove and a second mounting groove; the magnet mounting base includes a first mounting base and a second mounting base; wherein, when the drinking part is installed in place, the first magnet group and the second magnet group are coupled to each other, and one of the first mounting groove and the first mounting base and the second mounting base is located on the same vertical axis, and the second mounting groove and the other of the two are located on the same vertical axis.

[0019] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution uses the alignment design of the mounting groove and the mounting base axis to superimpose mechanical positioning function on the basis of magnetic coupling, so that the first magnet group and the second magnet group maintain the maximum magnetic attraction force when they are coupled to each other, thus ensuring the stability of operation.

[0020] In one embodiment of this utility model, the first magnet assembly and the mounting groove are detachably connected.

[0021] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: This solution breaks through the traditional fixed installation mode through a detachable connection structure, so that the magnet assembly and the mounting slot form an independent and separable modular component, which is convenient for replacement and installation.

[0022] In one embodiment of this utility model, the base includes: a base, the base having an internal accommodating space and an opening at the upper end of the base to connect the accommodating space with the outside of the base; a support cover, the support cover being located at the opening to cover the accommodating space; wherein, the drive motor and the second magnet assembly are installed in the accommodating space, and the drinking part is located on the side of the support cover away from the base.

[0023] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: This solution completely encloses the drive system in an independent space through the nested structure of the base and the support cover, which not only achieves waterproof protection during operation but also maintains a clean appearance.

[0024] In one embodiment of this utility model, the drinking part and the base are detachably connected.

[0025] Compared to existing technologies, the technical advantages of this solution are as follows: Traditional pet water fountains have a fixed connection between the drinking section and the base, allowing cleaning only through a narrow opening to wipe the inner wall of the cavity, which cannot thoroughly remove residual liquid. This solution, however, uses a split design, fully exposing the interior of the cavity, eliminating cleaning dead zones, and preventing damage to the drive components during disassembly.

[0026] By adopting the technical solution of this utility model, the following technical effects can be achieved: (1) The water in the drinking water section is directly disturbed by the water stirring device to form a continuous water flow, which destroys the static water environment required for bacterial reproduction and greatly improves the water quality retention capacity. (2) Vertical axial magnetic coupling transmission is adopted to realize non-contact power transmission, completely avoid the risk of water leakage of traditional mechanical seal structure, and improve torque transmission efficiency at the same time; (3) The magnet assembly and key components are detachably connected, simplifying the cleaning and maintenance process and reducing the cost of use.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, this utility model provides a pet water fountain, including: a main body; a drinking part 10, disposed on the upper part of the main body, and the upper end of the drinking part 10 forms a cavity for holding a target liquid; a water stirring device 20, installed on the main body, and the movable end of the water stirring device 20 extends into the interior of the cavity for performing a stirring action on the target liquid contained therein.

[0031] Specifically, the main body serves as the mounting base for the overall structure, providing a stable support platform for the drinking water unit 10. The drinking water unit 10 is fixed to the upper part of the main body, and its open top design allows pets to drink directly. The drive unit of the water stirring device 20 is embedded inside the main body, transmitting power to the movable end extending to the bottom of the cavity. When the device is activated, the movable end rotates or reciprocates within the liquid, generating water flow disturbance that causes the liquid to circulate from the bottom to the surface. This continuous movement effectively breaks up liquid stratification, preventing prolonged stagnation in localized areas.

[0032] In one embodiment of this utility model, the water stirring device 20 includes: a water stirring plate 101, which is disposed in the cavity and close to the bottom surface of the drinking part 10; and a driving mechanism, which is connected to the water stirring plate 101 to drive the water stirring plate 101 to rotate in a first plane; wherein the first plane is parallel to the bottom surface.

[0033] Specifically, the stirring plate 101 refers to a disc-shaped structure set in the bottom area of ​​the liquid container, which can be implemented by injection molding of plastic or metal parts.

[0034] Optionally, the edge of the stirring plate 101 can be designed as an arc-shaped protrusion or a blade structure to enhance the water flow disturbance effect.

[0035] Furthermore, the drive mechanism refers to a device that provides power through mechanical transmission or magnetic coupling. Specifically, it can be implemented by a structure in which a motor and a magnet assembly are combined, with the motor output shaft fixedly connected to the magnet mounting base 203 to transmit rotational torque.

[0036] Furthermore, the first plane refers to the horizontal motion trajectory plane that is parallel to the bottom surface of the container. Specifically, this can be achieved by adjusting the vertical distance between the drive shaft and the stirring plate 101 to ensure that the stirring plate 101 maintains a constant gap with the bottom surface when it rotates.

[0037] Specifically, the water stirring plate 101 is located at the bottom of the drinking chamber 10. When the drive mechanism is activated, the water stirring plate 101 rotates in a plane parallel to the bottom surface. During rotation, the water stirring plate 101 moves the liquid at the bottom, causing it to spread outwards and form a lateral circulation. Because the water stirring plate 101 is in close contact with the bottom surface, impurities deposited at the bottom are swept up by the water flow and dispersed throughout the water body with the circulation. The drive mechanism transmits the rotational power of the motor to the water stirring plate 101 through magnetic coupling, avoiding sealing problems caused by the mechanical shaft penetrating the container wall. This also ensures that the water stirring plate 101 rotates stably without physical contact, and the moving water flow is more attractive to pets, thereby increasing their interest in drinking.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown in one embodiment of this utility model, the main body includes a base 30, which is disposed at the lower end of the drinking part 10; the driving mechanism includes: a first magnet assembly 201, which is fixedly disposed on the upper side of the stirring plate 101; a drive motor, which is mounted on the base 30, and the drive shaft of the drive motor is close to the side of the drinking part 10 and perpendicular to the first plane; and a second magnet assembly 202, which is connected to the drive shaft; wherein the second magnet assembly 202 is coupled to the first magnet assembly 201.

[0039] Specifically, the base 30 refers to the support structure used to support the drive motor and connect the drinking water unit 10. It can be implemented by using an injection-molded shell structure. By isolating the drive motor from the water body, liquid can be prevented from seeping into the motor.

[0040] Furthermore, the first magnet group 201 refers to the permanent magnet array fixed on the upper side of the stirring plate 101, which is embedded in the surface of the stirring plate 101 in a centrally symmetrical manner.

[0041] Optionally, the first magnet group 201 and the second magnet group 202 may be neodymium iron boron magnets.

[0042] Furthermore, the fact that the drive shaft is perpendicular to the first plane means that the output shaft of the drive motor is perpendicular to the plane where the agitator plate 101 is located. Specifically, axial positioning can be achieved by setting a motor mounting bracket inside the base 30, so that the second magnet group 202 and the first magnet group 201 form axial magnetic coupling.

[0043] Furthermore, the connection between the second magnet assembly 202 and the drive shaft means that the magnet assembly forms a synchronous rotation structure with the drive shaft through the mounting base. Specifically, the magnet mounting base 203 can be sleeved on the end of the drive shaft and fixed by the keyway to ensure that the second magnet assembly 202 rotates synchronously with the drive shaft.

[0044] Since the drive mechanism is completely isolated from the water body through the bottom wall of the drinking section 10, the heat and mechanical vibration generated by the motor will not be directly transferred to the water, and the dynamic sealing structure required for the traditional drive shaft to penetrate the container wall is avoided.

[0045] In one embodiment of this utility model, the driving mechanism further includes a magnet mounting base 203, which is fixedly sleeved on the driving shaft to enable the magnet mounting base 203 to rotate along the second plane; wherein the second plane is parallel to the first plane, and the second magnet assembly 202 is fixedly disposed on the magnet mounting base 203.

[0046] Specifically, when the drive shaft rotates, it causes the magnet mounting base 203 to move in a circular motion within the second plane. Since the second plane is strictly parallel to the first plane where the stirring plate 101 is located, a stable magnetic force transmission path is formed between the second magnet group 202 and the first magnet group 201. The magnet mounting base 203 is fixedly sleeved onto the drive shaft through an interference fit, eliminating radial sway caused by traditional assembly clearances. When the drive motor starts, the rotation trajectory of the second magnet group 202 is restricted to a spatial range parallel to the first plane, ensuring that the effective coupling area between the two sets of magnets is always maintained above a set threshold.

[0047] In one embodiment of this utility model, the second magnet assembly 202 and the magnet mounting base 203 are detachably connected.

[0048] Specifically, the detachable connection means that the second magnet assembly 202 and the magnet mounting base 203 are fixed and separated by a mechanical structure, which can be achieved by snap-fit, thread or plug-in method. This structure allows the second magnet assembly 202 to be independently assembled and disassembled without damaging the overall components.

[0049] Furthermore, the magnet mounting base 203 refers to the support component used to fix the second magnet assembly 202. Specifically, it can be implemented by adopting an annular sleeve or a disc-shaped structure with positioning grooves. This component realizes the power transmission with the drive mechanism by being sleeved on the drive shaft.

[0050] Specifically, the second magnet assembly 202 is embedded in the positioning groove of the magnet mounting base 203 via a snap-fit ​​structure. When replacement or cleaning is required, the second magnet assembly 202 can be directly removed from the magnet mounting base 203. Since the second magnet assembly 202 is indirectly connected to the drive shaft through the magnet mounting base 203, its disassembly process only requires releasing the snap-fit ​​fixation, without disassembling the drive motor or the water agitator 101. This design eliminates the need to replace the entire drive mechanism during maintenance; only localized operations on the magnet components are required, thus avoiding the problem of the water agitator 20 failing to effectively disturb the water flow due to deterioration in magnet performance.

[0051] like Figure 5 and Figure 6 As shown, in one embodiment of this utility model, the upper end of the stirring plate 101 is provided with at least one mounting groove 205, and the first magnet group 201 is fixedly disposed in the mounting groove 205.

[0052] Specifically, the sidewall of the mounting groove 205 fits tightly against the side of the magnet, and the force generated when the stirring plate 101 rotates is absorbed by the groove structure. After the magnet is embedded in the mounting groove 205, its bottom surface contacts the bottom of the groove, and its top surface is flush with the surface of the stirring plate 101, preventing the magnet from shaking in the vertical direction.

[0053] Furthermore, the size design of the mounting groove 205 ensures that the magnet can only be inserted at a specific angle, guaranteeing that the polarity of the magnet corresponds to the second magnet group 202 of the drive mechanism. When the drive mechanism transmits rotational power through magnetic coupling, the constraint effect of the mounting groove 205 counteracts the vibration generated by the rotation of the stirring plate 101, keeping the magnetic field line distribution between the first magnet group 201 and the second magnet group 202 stable.

[0054] In one embodiment of this utility model, the upper end of the water stirring plate 101 is provided with a first mounting groove and a second mounting groove; the magnet mounting base 203 includes a first mounting base and a second mounting base; wherein, when the drinking part 10 is installed in place, the first magnet group 201 and the second magnet group 202 are coupled to each other, and one of the first mounting groove and the first mounting base and the second mounting base is located on the same vertical axis, and the second mounting groove and the other one are located on the same vertical axis.

[0055] Specifically, the first mounting groove and the second mounting groove refer to the recessed structures set on the upper end of the stirring plate 101 to accommodate the first magnet assembly 201. Specifically, they can be implemented by rectangular grooves or circular pits, and the installation position of the magnets is limited by the shape of the groove.

[0056] Furthermore, the first mounting base and the second mounting base refer to the magnet bearing structure fixed on the drive shaft. Specifically, they can be implemented using a plastic base with clips to fix the position of the second magnet assembly 202.

[0057] Specifically, when the drinking water unit 10 is assembled to the base 30, the first mounting groove of the stirring plate 101 and the first mounting seat of the magnet mounting base 203 automatically form a vertical alignment relationship under the influence of magnetic force, and the second mounting groove forms another alignment relationship with the second mounting seat; or the first mounting groove corresponds to the second mounting seat, and the second mounting groove corresponds to the first mounting seat. The depth of the mounting groove 205 and the height of the mounting seat are set such that when the two are in contact, the distance between the magnets is within the optimal magnetic coupling range, thereby maintaining the stability of magnetic force transmission during the rotation of the drive shaft.

[0058] In one embodiment of this utility model, the first magnet assembly 201 and the mounting groove 205 are detachably connected.

[0059] Specifically, detachable connection refers to the separation and reassembly of components through mechanical structures, which can be achieved using snap-fit ​​connections or threaded connections. This feature allows the magnet assembly to be independently detached from the stirring plate 101, avoiding cleaning dead spots caused by fixed installation.

[0060] Furthermore, the mounting groove 205 refers to a recessed structure on the surface of the stirring plate 101, which can be implemented using grooves corresponding to the shape of the magnets in the first magnet assembly 201. This feature provides positioning support for the magnet assembly and allows for separate cleaning of the magnet assembly from the groove through a detachable connection structure.

[0061] In one embodiment of this utility model, the base 30 includes: a base 301, which has an internal accommodating space 204 and an opening at its upper end to connect the accommodating space 204 with the outside of the base 301; and a support cover 302, which is located at the opening to cover the accommodating space 204; wherein, a drive motor and a second magnet assembly 202 are installed in the accommodating space 204, and a drinking part 10 is located on the side of the support cover 302 away from the base 301.

[0062] Specifically, the base 301 completely encloses the drive motor and the second magnet assembly 202 through the internal accommodating space 204, forming a physical isolation layer between it and the drinking water section 10.

[0063] Furthermore, the support cover 302 fits tightly against the opening edge of the base 301 during assembly, forming a waterproof sealing interface and serving as a mounting base for the drinking section 10. When cleaning or replacement of the drive components is required, the support cover 302 can be removed individually to expose the receiving space 204 without disassembling the entire drinking section 10 structure. The drinking section 10 is indirectly connected to the base 301 via the support cover 302, maintaining overall structural stability while preventing the drive components from directly contacting the water flow area.

[0064] Preferably, the drinking part 10 and the base 30 are detachably connected. Specifically, the upper end of the base 30 is recessed downwards, and the lower end of the drinking part 10 is structurally adapted to the upper end of the base 30. By placing the drinking part 10 on the upper end of the base 30 and rotating the drinking part 10 horizontally, the first magnet group 201 and the second magnet group 202 are coupled to each other, thus completing the installation of the drinking part 10.

[0065] Preferably, the rotation speed of the water stirring plate 101 can be adjusted manually or according to different situations. For example, when the pet is drinking water, the rotation speed of the water stirring plate 101 decreases or stops directly. When the pet is not drinking water and there is a water volume in the drinking part 10 that is higher than the set threshold, the water stirring plate 101 maintains the optimal rotation speed to inhibit bacterial growth.

[0066] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
