Description

Technical Field

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

[0002] As people's living standards improve, pets are becoming increasingly important in the family, and pet water fountains, as devices that provide clean drinking water for pets, have become popular among many pet owners.

[0003] In related technologies, pet water fountains typically employ a pump-free design, generally consisting of a water tank, a drinking trough, a water outlet pipe, and an electromagnetic component, with the electromagnetic component integrated into the fountain's base. The electromagnetic component usually includes a stator winding and a permanent magnet rotor. When the stator winding is energized, it generates a rotating magnetic field, which drives the permanent magnet rotor to rotate, thereby driving an impeller to transport water from the water tank to the water outlet pipe, and finally, the water flows to the drinking trough. While this design simplifies the structure to some extent, over long-term use, if the electromagnetic component fails, consumers often cannot replace it individually. Because the electromagnetic component is tightly integrated with the base, consumers often have to replace the entire fountain base, or even the entire fountain, leading to high operating costs, unnecessary resource waste, and a significant negative impact on the user experience. Utility Model Content

[0004] The main purpose of this utility model is to propose a pet water dispenser that aims to solve the technical problems in related technologies where the electromagnetic components cannot be replaced individually, resulting in high costs and high supply chain costs.

[0005] To achieve the above objectives, this utility model proposes a pet water fountain, which includes:

[0006] Upper shell, wherein a water storage cavity is formed inside the upper shell;

[0007] The base has a cavity, and the upper shell is detachably connected to the base;

[0008] An electromagnetic assembly, comprising a stator module and a permanent magnet rotor, wherein the stator module is detachably disposed within the cavity and the permanent magnet rotor is disposed within the water storage cavity;

[0009] The stator module is configured to drive the permanent magnet rotor to rotate in order to pump the water from the water storage chamber to the outside.

[0010] In one embodiment, the stator module includes a housing and a stator winding. An isolation cavity is provided inside the housing for limiting the stator winding. A groove is provided on the outer wall of the housing, and a bulge is provided on the upper shell. The bulge is located within the groove, and the permanent magnet rotor is accommodated within the bulge and exposed in the water storage cavity. An impeller is provided at one end of the permanent magnet rotor exposed in the water storage cavity.

[0011] In one embodiment, the isolation cavity further includes an illumination element, which is spaced apart from the stator winding and is configured to emit light through the isolation cavity into the water storage cavity.

[0012] In one embodiment, the inner wall of the cavity is provided with a snap-fit ​​element, and the outer shell of the stator module is provided with a corresponding snap-fit ​​part, which engages with the snap-fit ​​element.

[0013] In one embodiment, the upper shell has a convex bulge, and the pet water fountain also includes a sleeve and a water tank. The sleeve covers the side of the convex bulge facing away from the base. The sleeve has a water inlet and a transmission pipe. The water inlet connects the inner cavity of the convex bulge with the water storage cavity, and the transmission pipe connects the inner cavity of the convex bulge with the water tank.

[0014] In one embodiment, a cover is formed around the periphery of the water inlet, and the cover partially covers the water inlet.

[0015] In one embodiment, the pet water fountain further includes a sleeve, the upper shell having a protrusion, the sleeve covering the side of the protrusion facing away from the base, the pet water fountain further includes a water outlet pipe and a water trough, one side of the sleeve is connected to the water outlet pipe, and the inner cavity of the water outlet pipe is connected to the inner cavity of the protrusion and the water trough respectively.

[0016] In one embodiment, the drinking trough is provided with a water supply pipe at one end near the water storage cavity, and the water outlet pipe has a flared opening at the periphery of one end near the water supply pipe. The water supply pipe is detachably connected to the flared opening and communicates with the inner cavity of the water outlet pipe.

[0017] In one embodiment, the base is further provided with a ventilation slot for storing cleaning accessories.

[0018] In one embodiment, the opening direction of the ventilation slot is opposite to the opening direction of the cavity, and is spaced apart from the cavity.

[0019] The technical solution of this utility model detachably connects the upper shell and base of the pet water fountain, and sets a cavity in the base. The electromagnetic component includes a stator module and a permanent magnet rotor. The stator module is detachably located in the cavity, so when the stator module needs to be disassembled, since the stator module is a separate module, it only needs to be separated from the cavity in the base. This allows for replacement of the stator module without disassembling the base (i.e., without disassembling the entire pet water fountain). At the same time, the base, stator module, permanent magnet rotor, and upper shell can be easily separated, facilitating subsequent cleaning and replacement, and reducing replacement costs. Furthermore, since the stator module can be detached separately from the cavity in the base, compared to the prior art where the electromagnetic components (stator module and permanent magnet rotor) are integrated into the base of the water fountain, requiring the entire integrated electromagnetic component to be transported during subsequent sales and transportation, this utility model only requires transporting the detachable stator module, resulting in less space occupied during transportation and lower costs.

[0034] This utility model proposes a pet water dispenser 1000.

[0035] Please see Figures 1 to 7In one embodiment of this utility model, the pet water dispenser 1000 includes an upper shell 4, a base 1, and an electromagnetic component 2. A water storage cavity 41 is formed inside the upper shell 4. The base 1 has a cavity 11, and the upper shell 4 and the base 1 are detachably connected. The electromagnetic component 2 includes a stator module 21 and a permanent magnet rotor 22. The stator module 21 is detachably disposed in the cavity 11, and the permanent magnet rotor 22 is disposed in the water storage cavity 41. The stator module 21 is configured to drive the permanent magnet rotor 22 to rotate so as to pump the water in the water storage cavity 41 to the outside.

[0036] In this embodiment, it should be noted that the connection method between the upper shell 4 and the base 1 includes, but is not limited to, snap-fit ​​and plug-in methods, and is not limited here. Combined with Figure 4 The base 1 has a cavity 11, the shape and size of which are adapted to the shape and size of the stator module 21. It is understood that the cavity 11 is located on the side of the base 1 facing the upper shell 4, and it does not extend through the entire base 1. Four support legs are also provided on the side of the base 1 facing away from the opening of the cavity 11, distributed along the four corners of the base 1 to support the entire base 1. It should be noted that when the pet water fountain 1000 starts operating, the stator module 21 is energized to generate a rotating magnetic field, which drives the permanent magnet rotor 22 to rotate. Since the permanent magnet rotor 22 is exposed within the water storage cavity 41, it can pump water out of the water storage cavity 41 to the outside, which includes the water trough 5, the area for pets to drink, etc. The stator module 21 is detachably located within the cavity 11. The detachable connection methods include, but are not limited to, snap-fit, direct limiting, and bolt connection, etc., and are not limited here. In one embodiment, threads are provided on the inner wall of the cavity 11, and matching threads are provided on the outer shell of the stator module 21. The stator module 21 is fixed within the cavity 11 via the threaded connection; disassembly is achieved simply by rotating the stator module 21. In another embodiment, a slot is provided on the inner wall of the cavity 11, and matching clips are provided on the outer shell of the stator module 21. During installation, the clips of the stator module 21 are aligned with the slot and pressed down firmly to engage the clips. During disassembly, the stator module 21 is pulled outwards to disengage the clips. In yet another embodiment, a magnet is provided at the bottom of the cavity 11, and a matching magnetic material is provided at the bottom of the stator module 21. The stator module 21 is fixed within the cavity 11 by the attraction between the magnet and the magnetic material. When the stator module 21 needs to be replaced, it can be removed by overcoming the magnetic force. It is understandable that the stator module 21 can also be directly confined within the cavity 11, the size of which is adapted to the size of the stator module 21.

[0037] The technical solution of this utility model detachably connects the upper shell 4 and the base 1 of the pet water fountain 1000, and sets a cavity 11 on the base 1. The electromagnetic component 2 includes a stator module 21 and a permanent magnet rotor 22. The stator module 21 is detachably disposed in the cavity 11, so that when the stator module 21 needs to be disassembled, since the stator module 21 is a separate module, it is only necessary to separate the stator module 21 from the cavity 11 on the base 1, so that the base 1 can be disassembled without disassembling the base (i.e., the entire pet water fountain 1000 can be replaced). At the same time, the base 1, the stator module 21, the permanent magnet rotor 22 and the upper shell 4 can be easily separated, which facilitates subsequent cleaning and replacement and reduces replacement costs. In addition, since the stator module 21 can be detached separately from the cavity 11 on the base 1, compared with the prior art where the electromagnetic component 2 (stator module 21 and permanent magnet rotor 22) is integrated into the base of the water fountain, the entire electromagnetic component integrated into the base of the water fountain needs to be transported during subsequent sales and transportation. Furthermore, since this utility model only requires the transport of the separately detachable stator module 21 during subsequent sales and transportation, the space occupied during transportation is smaller and the cost is lower.

[0038] In one embodiment of this utility model, the stator module 21 includes a housing and a stator winding 212. An isolation cavity 211 is provided inside the housing for limiting the stator winding 212. A groove 213 is provided on the outer wall of the housing, and a protrusion 42 is provided on the upper shell 4. The protrusion 42 is limited within the groove 213. The permanent magnet rotor 22 is accommodated within the protrusion 42 and exposed in the water storage cavity 41. An impeller 23 is provided at one end of the permanent magnet rotor 22 exposed in the water storage cavity 41.

[0039] In this embodiment, combined with Figure 3 and Figure 7 The outer casing has an isolation cavity 211 for limiting the stator winding 212 and a groove 213 for limiting the protrusion 42. The groove 213 and the isolation cavity 211 are not connected. It can be understood that the protrusion 42 is directly limited and engaged in the groove 213, and the dimensions of the protrusion 42 and the groove 213 are adapted to each other. Figure 3It is understood that a protrusion 42 is formed on the side of the upper shell 4 facing the base 1, and the protrusion 42 houses the permanent magnet rotor 22. The size of the inner cavity of the protrusion 42 is adapted to the size of the permanent magnet rotor 22. The permanent magnet rotor 22 has a rotating shaft, which is non-rotatably confined within the protrusion 42, and the permanent magnet rotor 22 is sleeved on the rotating shaft. An impeller 23 is provided at one end of the permanent magnet rotor 22 exposed in the water storage cavity 41, and the impeller 23 is directly installed at the end of the permanent magnet rotor 22 away from the rotating shaft. This direct connection method reduces the transmission links and improves the efficiency and stability of water flow drive. Specifically, in the pet water dispenser 1000 provided by this utility model, it should be noted that the upper shell 4 has a water storage cavity 41, which is a water tank for storing water. The water storage cavity 41 is a space enclosed by the inner wall of the upper shell 4, and the permanent magnet rotor 22 in the protrusion 42 is exposed in the water storage cavity 41. The drinking trough 5 is located above the water storage cavity 41 and the electromagnetic component 2. The above configuration allows water to flow from the water storage chamber 41 to the drinking trough 5 through the permanent magnet rotor 22, preventing water from stagnating in the drinking trough 5 for a long time, reducing the chance of bacterial growth, and ensuring that the water in the drinking trough 5 is always fresh.

[0040] In one embodiment of the present invention, the isolation cavity 211 also accommodates an illumination element 214, which is spaced apart from the stator winding 212. The illumination element 214 is configured to emit light through the isolation cavity 211 into the water storage cavity 41.

[0041] In this embodiment, combined with Figure 2 and Figure 6To enhance the user experience of the pet water fountain 1000, an illumination element 214 is installed within the first isolation chamber 211. The color change of the illumination element 214 allows the user to understand the water level in the water storage chamber 41, eliminating the need for frequent checks. It is understood that the illumination element 214 is preferably an LED light. Referring to the figure, a circuit board 215 is also located within the isolation chamber 211. The illumination element 214 is electrically connected to the circuit board 215 via a ribbon cable. The circuit board 215 is externally connected to a power plug 216, which enables power transmission. The power plug 216 may include, but is not limited to, a USB connector or a three-prong plug. Specifically, when the illumination element 214 is white, it indicates sufficient water; red indicates that water needs to be added. It should be noted that during actual use, the illumination element 214 can emit light through the isolation chamber 211 into the water storage chamber 41. In one embodiment, the isolation chamber 211 and the upper shell 4 are made of transparent or semi-transparent materials, allowing the illumination element 214 to directly emit light through the transparent isolation chamber 211 into the water storage chamber 41. It is understood that the material of the isolation cavity 211 here includes, but is not limited to, polycarbonate (PC), polymethyl methacrylate (PMMA), acrylonitrile-butadiene-styrene copolymer (ABS), polypropylene (PP plastic), etc., and is not limited here. In another embodiment, since the light from the lighting element 214 needs to pass through the isolation cavity 211 and the protrusion 42 for illumination, a light-transmitting waterproof cover is provided on the outside of the lighting element 214 to prevent water from entering the lighting element 214. It is understood that the material of the light-transmitting waterproof cover is transparent or semi-transparent, including, but not limited to, acrylonitrile-butadiene-styrene copolymer (ABS), polypropylene (PP plastic), etc., and is not limited here. The shape of the light-transmitting waterproof cover is not limited and can be designed as circular, square, etc. The above arrangement, by setting up the lighting element 214, allows the user to intuitively understand the water level in the water storage cavity 41; at the same time, when the lighting element 214 or other components malfunction, since the lighting element 214 is integrated with the isolation cavity 211 where the stator winding 212 is located, subsequent replacement and maintenance are more convenient.

[0042] In one embodiment of this utility model, the inner sidewall of the cavity 11 is provided with a snap fastener, and the outer shell of the stator module 21 is provided with a corresponding snap fastener, which engages with the snap fastener.

[0043] In this embodiment, to facilitate quick installation and removal of the stator module 21, a latching element is provided on the inner wall of the cavity 11, and a matching latching part is provided on the outer shell of the stator module 21. When the stator module 21 is inserted into the cavity 11, the latching part and the latching element engage with each other, forming a stable connection. The latching element typically has a certain degree of elasticity, allowing it to elastically deform when the stator module 21 is inserted. After the stator module 21 is fully inserted, the latching element returns to its original shape, locking the latching part of the stator module 21 and preventing it from loosening or falling off. It is understood that, combined with... Figure 4A two-way latching component is provided on the inner wall of the cavity 11, and a corresponding two-way latching part is provided on the outer shell of the stator module 21. The two-way latching component is usually designed with elastic hooks or protrusions in two directions, which can simultaneously latch the stator module 21 from two directions.

[0044] In one embodiment of this utility model, the upper shell 4 has a protrusion 42, and the pet water dispenser 1000 also includes a sleeve 6 and a water tank 5. The sleeve 6 covers the side of the protrusion 42 facing away from the base 1. The sleeve 6 has a water inlet 61 and a transmission pipe 63. The water inlet 61 connects the inner cavity of the protrusion 42 with the water storage cavity 41, and the transmission pipe 63 connects the inner cavity of the protrusion 42 with the water tank 5.

[0045] In this embodiment, it can be understood that, in combination Figure 3 The sleeve 6 is fitted onto the side of the convex shroud 42 facing away from the base 1. The sleeve 6 not only transports water from the water storage chamber 41 into the convex shroud 42, but also pumps it out of the water storage chamber 41, i.e., to the drinking trough 5 located outside the water storage chamber 41, under the action of the permanent magnet rotor 22 within the convex shroud 42. Because it is fitted onto the convex shroud 42, it prevents the permanent magnet rotor 22 from moving. Specifically, the sleeve 6 covers the side of the convex shroud 42 facing away from the base 1, i.e., above the permanent magnet rotor 22. The sleeve 6 and the bottom wall of the upper shell 4 enclose a space for the impeller 23 of the permanent magnet rotor 22 to rotate. It should be noted that, in conjunction with... Figure 2 and Figure 3 The transmission pipe 63 is located on one side of the sleeve 6 and extends in the direction away from the base 1, communicating with the inner cavity of the water trough 5 and the bulge 42 respectively; the water inlet 61 is spaced apart from the transmission pipe 63 and is located close to the permanent magnet rotor 22 so that the water flow can enter the inner cavity of the bulge 42 more smoothly. Under the drive of the stator module 21, the rotation of the permanent magnet rotor 22 transports the water flow to the transmission pipe 63, and then transports the water to the water trough 5 to meet the pet's drinking needs.

[0046] In one embodiment of the present invention, a cover 62 is formed around the water inlet 61, and the cover 62 covers part of the water inlet 61.

[0047] In this embodiment, in order to effectively control the water flow velocity, reduce the impact of the water flow on the inlet 61, and achieve the effect of reducing water pressure, combined with Figure 3 A cover 62 is formed around the periphery of the inlet 61, which partially covers the inlet 61, effectively reducing the pressure of water flowing from the storage chamber 41 into the bulge 42. The cover 62 also prevents the water in the storage chamber 41 from forming eddies when the water level is low. Figure 3The cover 62 extends from bottom to top and bends as it extends. The cover 62 and the sleeve 6 are exposed on the outer wall of the water storage cavity 41, forming a water inlet space 62a. This water inlet space 62a is arranged intersecting the orientation of the water inlet 61. Due to the presence of the cover 62, the water in the water storage cavity 41 flows from the water inlet space 62a formed by the cover 62 and the sleeve 6 exposed on the outer wall of the water storage cavity 41 to the water inlet 61. Then, under the action of the permanent magnet rotor 22, the water is transported to the drinking trough 5, reducing water turbulence, improving water flow stability, and thus improving the overall operating efficiency of the pet water fountain 1000.

[0048] In one embodiment of this utility model, the pet water fountain 1000 also includes a sleeve 6, and the upper shell 4 has a protrusion 42. The sleeve 6 covers the side of the protrusion 42 facing away from the base 1. The pet water fountain 1000 also includes a water outlet pipe 3 and a water tank 5. One side of the sleeve 6 is connected to the water outlet pipe 3, and the inner cavity of the water outlet pipe 3 is connected to the inner cavity of the protrusion 42 and the water tank 5 respectively.

[0049] In this embodiment, to achieve a stable water supply for the pet water fountain 1000, the outlet pipe 3 connects the inner cavity of the convex shroud 42 and the water trough 5. Water from the storage chamber 41 enters the convex shroud 42 through the inlet 61 of the sleeve 6. After the stator module 21 in the base 1 is powered on, it drives the permanent magnet rotor 22 inside the convex shroud 42 to rotate. The permanent magnet rotor 22 transports the water to the transmission pipe 63 of the sleeve 6. The transmission pipe 63 connects to the outlet pipe 3, and the water is finally delivered to the water trough 5, thus providing the pet with continuous clean drinking water. It is understood that the water trough 5 can also be equipped with a filter tray to filter impurities. Figure 2 and Figure 3 It should be noted that the water outlet pipe 3 can be an integrally formed structure with the sleeve 6, that is, the water outlet pipe 3 is formed by extending the transmission pipe 63 of the sleeve 6; or it can be a water outlet pipe 3 detachably connected to the transmission pipe 63 of the sleeve 6, with the inner cavity of the water outlet pipe 3 communicating with the inner cavity of the sleeve 6. The arrangement of the water outlet pipe 3 is not limited here and can be set according to actual needs. The drinking trough 5 is set above the water storage chamber 41. The connection between the drinking trough 5 and the water outlet pipe 3 can be an integrally formed structure, or it can be connected by snap-fit, plug-in, or other methods. Specifically, the material of the water outlet pipe 3 includes, but is not limited to, polypropylene (PP), polyvinyl chloride (PVC), polymethyl methacrylate (PMMA, acrylic), ABS (acrylonitrile-butadiene-styrene copolymer), etc., and is not limited here.

[0050] In one embodiment of the present invention, a water supply pipe 51 is provided at one end of the drinking trough 5 near the water storage chamber 41, and a flared end 31 is formed at one end of the water outlet pipe 3 near the water supply pipe 51. The water supply pipe 51 is detachably connected to the flared end 31 and communicates with the inner cavity of the water outlet pipe 3.

[0051] In this embodiment, combined with Figure 2 It should be noted that the connection method between the water supply pipe 51 and the water outlet pipe 3 includes, but is not limited to, an integral molding method, and can also be connected by a plug-in method. For ease of maintenance and cleaning, the flared end 31 design allows the water supply pipe 51 to be easily inserted into or removed from the inner cavity of the water outlet pipe 3, making the drinking trough 5, the water outlet pipe 3, and the water storage chamber 41 easy to disassemble and clean. It is understood that the shape of the flared end 31 includes, but is not limited to, cylindrical, stepped, and trumpet-shaped shapes, with a trumpet-shaped design being preferred here. The material of the water supply pipe 51 includes, but is not limited to, soft rubber materials such as ABS (acrylonitrile-butadiene-styrene copolymer), polypropylene (PP), polyvinyl chloride (PVC), polymethyl methacrylate (PMMA), TPE (thermoplastic elastomer), TPU (thermoplastic polyurethane), and silicone, and is not limited here. Figure 2 To achieve a precise guiding connection between the water supply pipe 51 and the water outlet pipe 3, one end of the water outlet pipe 3 is formed into a flared end 31, allowing the water supply pipe 51 to be more easily aligned and inserted into the inner cavity of the water outlet pipe 3 during insertion. The flared end 31 increases the contact area at the connection point. By rationally designing the shape and size of the flared end 31, it can better fit against the outer wall of the water supply pipe 51, thereby improving the sealing performance. It is understood that the flared end 31 can be manufactured by injection molding.

[0052] In one embodiment of this utility model, the base 1 is also provided with a ventilation groove 12, which is used to store cleaning accessories.

[0053] In this embodiment, combined with Figure 4 To further facilitate the storage of accessories for the pet water fountain 1000 and ensure these items have a fixed storage location to avoid clutter, the base 1 also has a ventilation slot 12. The ventilation slot 12 is used to store cleaning accessories such as cleaning brushes. The ventilation slot 12 is connected to outside air, thus achieving ventilation after the cleaning brushes and other cleaning accessories have been cleaned. It is understood that the ventilation slot 12 can be located on the side of the base 1 for easy operation and removal of the stored items. The ventilation slot 12 can also be located on the side of the base 1 facing away from the water storage chamber 41, using evaporation as a specific implementation method (see the next embodiment). It should be noted that the ventilation slot 12 is not connected to the water storage chamber 41, nor is it connected to the cavity 11 formed in the base 1.

[0054] In one embodiment of the present invention, the opening direction of the ventilation slot 12 is opposite to the opening direction of the cavity 11, and is spaced apart from the cavity 11.

[0055] In this embodiment, combined with Figure 4It should be noted that a ventilation slot 12 is provided on the bottom of the base 1 (facing away from the water tank 5), with the opening of the ventilation slot 12 facing away from the opening of the cavity 11. After cleaning accessories such as cleaning brushes clean the water storage cavity 41 inside the upper shell 4, the damp cleaning brushes can be dried along the ventilation slot 12 to prevent them from being stored in a damp state. Furthermore, because the ventilation slot 12 is positioned facing away from the opening of the cavity 11, its opening is not visible when the pet water fountain 1000 is in normal use. Additionally, the fact that the opening of the ventilation slot 12 faces away from the cavity 11 reduces the possibility of dust and debris entering the ventilation slot 12, keeping the inside of the ventilation slot 12 clean and extending the lifespan of the storage components; it also reduces the possibility of pets accidentally contacting the inside of the ventilation slot 12, preventing pets from sticking their paws into the ventilation slot 12 out of curiosity, thus reducing the risk of injury. Figure 4 Understandably, in order to facilitate the drying of cleaning accessories such as cleaning brushes, the wall of the ventilation slot 12 is rounded from the end away from the opening to the end near the opening, so that water droplets of cleaning accessories in a wet state can flow along the ventilation slot 12 to the outside, so as to avoid mold growth and ensure thorough drying; here, the cleaning accessories such as cleaning brushes in a wet state can also be dried naturally by evaporation.
