[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] like Figures 1 to 3 As shown, a water-lifting device of a pet drinking fountain includes a shell 1, a stirring assembly 2 installed on the shell 1, and a driving assembly 3 connected to the stirring assembly 2. The shell 1 has a lifting cavity 101, the lower side of the lifting cavity 101 is a water inlet 102, and the upper side is a water outlet 103. The shell 1 is also provided with a water inlet 11 connected to the water inlet 102 and a water outlet 12 connected to the water outlet 103. The stirring assembly 2 is arranged in the lifting cavity 101, and is used to guide the liquid in the water inlet 102 to flow to the water outlet 103. The driving assembly 3 is used to drive the stirring assembly 2 to rotate in the lifting cavity 101. It will be used as a pumping power component, that is, the stirring component 2 and the driving component 3 are integrated on an independent shell 1, and can be used by simply installing it on the pet water dispenser. The driving component 3 drives the stirring component 2 to rotate to stir the water in the lifting cavity 101 and provide a vortex to rotate the water in the lifting cavity 101. The cross-sectional shape of the liquid surface is an inverted bell shape (a parabola with an opening facing upward). The high liquid levels on both sides will climb along with the inner wall of the lifting cavity 101, and overflow to the water outlet 103 when it is higher than the inner wall, and finally flow out from the water outlet 12. Moreover, the driving component 3 and the stirring component 2 of this solution are easier to disassemble relative to the shell 1, so as to facilitate cleaning or maintenance after long-term use, maintain hygiene, prevent water pollution and affect the user experience.

[0047] Specifically, the stirring component 2 of this embodiment is in contact with water when working, while the driving component 3 needs to be separated from the contact with water. Therefore, a partition 4 for sealing the upper end of the lifting cavity 101 is provided on the upper side of the water outlet 103 of this solution, and the driving component 3 is arranged on the outside of the lifting cavity 101 to achieve the effect of water-electricity separation. It can be directly connected to the outer periphery of the shell 1, or it can be connected inside the shell 1 and separated from the lifting cavity 101 by the partition 4. Correspondingly, when the driving component 3 adopts different installation positions, its connection method with the stirring component 2 can also be correspondingly set to direct docking or docking through intermediate transmission parts, such as docking through intermediate transmission parts such as transmission gears, transmission belts, transmission chains or turbine worm gears. It can adapt to different directions of the output shaft and the stirring component 2 after the drive component 3 is installed to achieve transmission docking, and it is also convenient to use as a speed control transmission docking,

[0048] In this solution, the driving component 3 is preferably installed on the partition 4. In this embodiment, it can be understood that the partition 4 covers the upper end of the lifting cavity 101 and the water outlet 103, so that the driving component 3 is separated on the outside to avoid contact with water during operation. Usually, the driving component 3 is a motor, and its driving end passes through the partition 4 and extends into the lifting cavity 101 and is installed with the stirring component 2. Of course, in order to improve the separation effect, a sealing ring or sealing ring with the partition 4 can be added to the driving end of the driving component 3 to achieve a better water-proof effect.

[0049] In the present invention, the water outlet 103 is a temporary water storage tank located on the outer peripheral side of the lifting inner cavity 101, and the bottom of the temporary water storage tank is lower than the highest position H of the inner wall of the lifting inner cavity 101. The temporary water storage tank is convenient for collecting water from multiple directions of the lifting inner cavity 101 and draining it to the water outlet 12 for outflow.

[0050] like Figure 4 As shown, as the first embodiment of the water outlet 103 of the utility model, the outer wall 1031 of the temporary water storage tank is higher than the inner wall 1032 of the temporary water storage tank, and the partition plate 4 contacts the upper end of the outer wall 1031 of the temporary water storage tank.

[0051] like Figure 5 As shown, as the second embodiment of the water outlet 103 of the utility model, the outer wall 1031 of the temporary water storage tank is lower than the inner wall 1032 of the temporary water storage tank, and the partition 4 has an extension 41 extending downward, and the partition 4 is in contact with the outer wall 1031 of the temporary water storage tank through the extension 41. This second embodiment can further compress the longitudinal space, that is, compared with the first embodiment, the driving assembly 3 can be closer to the upper side of the lifting cavity 101, thereby optimizing the overall size of the water lifting device.

[0052] In addition, if Figure 2 As shown, in order to further improve the drainage effect, the inner wall of the lifting cavity 101 has a guide surface extending to the temporary water storage tank in an arc or inclined surface at the highest position H of the inner wall, so that when the stirring assembly 2 is working, the water climbing along the inner wall of the lifting cavity 101 can flow into the water outlet 103 better.

[0053] When the water lifting device of the utility model is in use, the water inlet 102 at the lower end is inserted into the water tank, and the water in the water tank enters the water inlet 102 from the water inlet 11 and rises to the lifting inner cavity 101 to be stirred by the stirring component 2, so as to cope with low water level and improve efficiency. Figure 2 , Figure 3As shown, a drainage component 5 is further provided at the lower end of the rotating shaft 21, and the drainage component 5 has a drainage blade located in the water inlet 102, and the drainage component 5 rotates with the rotating shaft 21 to promote the liquid on the outside to enter the water inlet 102 from the water inlet 11. The drainage component 5 adopts a propeller-like structure, and rotates with the rotating shaft 21 to stir the water in the water inlet 102, so that the water in the water inlet 102 quickly forms a vortex, and at the same time drives the water in the water tank to enter the water inlet 102 faster.

[0054] Specifically, as the first embodiment of the water inlet 11 of the utility model, the water inlet 11 includes multiple water inlets 11, and the multiple water inlets 11 are evenly distributed along the circumference of the water inlet portion 102. In the first embodiment, the directions of the multiple water inlets 11 are all opposite to the center of the water inlet portion 102.

[0055] like Figure 6 , Figure 7 As shown, as the second embodiment of the water inlet 11 of the utility model, the water inlet 11 includes at least two, and the water inlet direction of the two water inlets 11 is the tangential direction of the water inlet portion 102. In this second embodiment, the water flow entering from the two water inlets 11 flows along the tangential direction, which can form a vortex faster.

[0056] In addition, if Figure 8 As shown, in order to further improve the water quality, in the present invention, a filter assembly 6 is further installed on the outer side of the water inlet 102, and the filter assembly 6 covers the water inlet 11. The filter assembly 6 can be a material assembly with a specific filtering function such as filter cotton, which is detachably installed on the outer side of the water inlet 102, so that when the water lifting device is used, the water in the water tank can be filtered first and then lifted to the drinking water cavity for the pet to drink.

[0057] In the present utility model, if Fig. 9 As shown, in order to improve the effect of the water-lifting device on the formation of vortex and lifting of water flow, the inner wall of the lifting inner cavity 101 is an annular cylinder with a width gradually decreasing from the water outlet 103 to the water inlet 102, or the inner wall of the lifting inner cavity 101 is an annular cylinder with an equal width from the water outlet 103 to the water inlet 102. The inner wall of the annular cylinder with equal diameter or the annular cylinder with a wide top and a narrow bottom can cooperate with the stirring component 2 to stir and better generate vortex. Moreover, an annular portion 1011 arranged in a threaded shape can also be provided on the inner wall of the lifting inner cavity 101 to further cooperate with the vortex generated after the stirring component 2 is stirred. In this embodiment, the annular portion 1011 can be a structure of an annular protrusion, or a structure of an annular groove, and its threaded surrounding manner cooperates with the water flow stirred into a vortex, further assisting the water flow to climb along the inner wall. In this embodiment, the direction of rotation of the thread of the annular portion 1011 is adapted to the stirring direction of the stirring component 2, and in particular, the stirring blade 22 of the stirring component 2 adopts a spiral blade structure (such as Fig.10 , Fig.11 ), when the water flow is stirred by the stirring assembly 2, it can climb along the annular portion 1011 to achieve water lifting. When the stirring blade 22 of the stirring assembly 2 adopts a straight blade structure (such as Fig.12 , Fig.13 ), the rotation direction of the annular portion 1011 is not restricted.

[0058] As an element providing vortex to the water flow in the present invention, the stirring assembly 2 includes a rotating shaft 21 connected to the driving assembly 3, and a stirring blade 22 arranged on the outer periphery of the rotating shaft 21. The stirring blade 22 rotates with the rotating shaft 21 and stirs the liquid in the lifting cavity 101, so that the liquid forms a vortex and enters the water outlet 103 along the inner wall of the lifting cavity 101. Here, a variety of ways and structures for forming stirring vortices are proposed.

[0059] In the first embodiment of the stirring blade 22 of the utility model, the stirring blade 22 is spirally arranged along the axial direction of the rotating shaft 21 and around the outer circumference of the rotating shaft 21. The stirring blade 22 in a spiral sheet shape can guide the water flow to flow upward along itself during the rotating stirring process. This embodiment is not shown in the figure.

[0060] like Fig.10 and Fig.11 As shown in the second embodiment of the stirring blade 22 of the utility model, the stirring blade 22 includes multiple pieces, and the multiple stirring blades 22 are arranged in a twisted shape along the axial direction of the rotating shaft 21. During the rotating stirring process, the blades can provide a large vortex to the water flow. Fig.10 A structure of a drainage component 5 is added to the lower side of the rotating shaft 21 .

[0061] like Fig.12 As shown, in the third embodiment of the stirring blade 22 of the present invention, the stirring blade 22 includes a plurality of straight blades, and the plurality of stirring blades 22 are evenly distributed on the periphery of the rotating shaft 21. As a replaceable structure of the stirring blade 22 in the present invention, it can also generate vorticity for the water flow during the rotation process.

[0062] like Fig.13 As shown, in the fourth embodiment of the stirring blade 22 of the utility model, the stirring blade 22 includes multiple pieces, and the stirring blade 22 is a sheet-shaped piece that is wide at the top and narrow at the bottom, and the multiple stirring blades 22 are evenly distributed on the outer periphery of the rotating shaft 21. As a replaceable structure of the stirring blade 22 in the utility model, it can also generate vortex to provide water flow during rotation.

[0063] In the embodiment of the utility model, the lower end of the rotating shaft 21 is rotatably connected in the water inlet 102, which can adopt a convex shaft type with a simple structure. Correspondingly, a groove for inserting the rotating shaft 21 is provided in the water inlet 102 to facilitate the rotation of the rotating shaft 21 and prevent it from shifting. Fig.14 As shown, a rotating connection member 7 can also be added to the lower end of the rotating shaft 21 to be installed on the water inlet part 102. In the embodiment, the lower end of the rotating shaft 21 has an upwardly recessed installation opening, and the rotating connection member 7 is a support shaft, which is inserted into the installation opening of the rotating shaft 21 through one end, and the other end is inserted into the groove of the water inlet part 102 to achieve a rotatable connection to the rotating shaft 21.

[0064] Of course, if Fig.15 As shown, in order to improve the stability of rotation and reduce resistance, a bearing may be installed in the water inlet portion 102, and the lower end of the rotating shaft 21 is directly installed on the bearing.

[0065] Based on this, Fig.16 , Fig.17 As shown, the utility model also provides a pet drinking fountain, including a drinking fountain housing 9, wherein the drinking fountain housing 9 has a water storage chamber 901, and the drinking fountain housing 9 is provided with a drinking water chamber 902.

The water lifting device of the utility model is directly mounted on the drinking fountain housing 9, and its water inlet 11 is inserted into the water storage chamber 901, and the driving component 3 drives the stirring component 2 to rotate, so that the water in the water inlet 102 climbs along the lifting inner chamber 101, and after entering the water outlet 103, it flows out from the water outlet 12 and naturally falls into the drinking water chamber 902 for the pet to drink. Moreover, when not in use for a long time or needs to be cleaned, the present invention can remove the entire water-lifting device from the water dispenser housing 9, and can also remove the drive assembly 3 and the stirring assembly 2 from the housing 1 separately to facilitate cleaning.
