[0033] As shown in FIG. 1 to FIG. 12 , an embodiment of the water treatment mechanism provided by the present application is shown.

[0034] As shown in Figures 1 and 2, the water treatment mechanism 100 proposed in this application includes a housing 1, a water delivery component 10, a water channel component 2, a water pump 3 and a filter device 400.

The water delivery assembly 10 is connected to the waterway assembly 2 via a connecting hole connecting the two chambers. The waterway assembly 2 also has a waterway connection with the water pump 3 and filter device 400. This design ensures that the various components are closely connected. The compact structure also enables the entire water treatment mechanism 100 to achieve efficient water treatment while occupying a small space.

[0036] In this embodiment, as shown in Figures 3 to 7, the adapter 21 includes a middle shell 22 and a left shell 23 and a right shell 24 assembled on both sides of the middle shell 22. The third flow path 21a is at least partially formed in the middle shell 22 and the left shell 23, and the fourth flow path 21b is at least partially formed in the middle shell 22 and the right shell 24. In conjunction with Figure 2, since the water path assembly 2 needs to cooperate with various components in the pet water dispenser 200, including the water inlet pipe 10a and the water outlet pipe 10b arranged in a front-to-back position and connected to the water storage area and the drinking water area of ​​the water tank 210 respectively, the water inlet and outlet ends of the water pump 3 arranged in the up-down direction, and the water outlet and water inlet ends of the filter device 400 arranged in the up-down direction, the spatial positions of the above-mentioned inlet / outlet ends are not on the same plane, resulting in the water path assembly 2 being unable to be formed as a whole and needs to be split into various components to form The adapter 21 includes a middle shell 22 and a left shell 23 and a right shell 24 assembled on both sides of the middle shell 22. The water inlet flow section 21c is at least partially formed in the middle shell 22 and the left shell 23. The third flow path 21a is at least partially formed in the middle shell 22 and the left shell 23. The fourth flow path 21b is at least partially formed in the middle shell 22 and the right shell 24. The complete water path assembly 2 is split into individual components to ensure the smooth flow and integrity of each flow section, and the split components are also easy to assemble.

[0037] In this embodiment, as shown in Figure 3, a filtering water supply flow section 42 is formed in the adapter 21, and the water outlet end of the water pump 3 is connected to the water inlet end of the filter device 400 through the filtering water supply flow section 42. The filtering water supply flow section 42 is at least partially formed in the middle shell 22, the left shell 23 and the right shell 24. In this way, the water flowing out of the water outlet end of the water pump 3 flows to the water inlet end of the filter device 400 through the filtering water supply flow section 42, so that the water is pumped into the filter device 400 through the water pump 3 for treatment.

[0038] In this embodiment, as shown in FIG3 , an independent water inlet flow section 21 c and a filtered return water flow section 21 d are further formed in the adapter 21. The third flow path 21 a includes the water inlet flow section 21 c, and the fourth flow path 21 b includes the filtered return water flow section 21 d. The water inlet pipe 10 a is connected to the water inlet end of the water pump 3 through the water inlet flow section 21 c, and the water outlet end of the water pump 3 is connected to the water inlet end of the filter device 400 through the filtered water supply flow section 42. The water outlet end of the filter device 400 is connected to the water outlet pipe 10 b through the filtered return water flow section 21 d. The water inlet pipe 10 a and the water outlet pipe 10 b are aligned in the front-to-back direction. The top surface of the middle shell 22 is provided with an inlet of the water inlet flow section 21 c and a filter. The outlet of the rear return water flow section 21d, the inlet of the inlet flow section 21c and the outlet of the post-filtration return water flow section 21d are aligned in the front-to-back direction, the outer side surface of the left shell 23 is provided with the outlet of the inlet flow section 21c, and the outer side surface of the right shell 24 is provided with the inlet of the post-filtration return water flow section 21d. The outlet of the inlet flow section 21c and the inlet of the post-filtration return water flow section 21d are aligned in the left-to-right direction. When the axis of the inlet of the post-filtration return water flow section 21d intersects with the axis of the outlet of the post-filtration return water flow section 21d, the middle shell 22 and the left shell 23 are spliced ​​to form a first connecting flow section 223 extending along the front-to-back direction, and the inlet flow section 21c includes the first connecting flow section 223.

[0039] In this embodiment, the inlet of the water inlet flow section 21c and the outlet of the filtered return water flow section 21d are aligned in the front-to-back direction, and the outlet of the water inlet flow section 21c and the inlet of the filtered return water flow section 21d are aligned in the left-to-right direction, so that the pipeline is symmetrical and regular, and the installation and disassembly of the corresponding components are more convenient. Since the water inlet flow section 21c has a stroke in the up-down direction, the front-to-back direction, and the left-to-right direction, and the overall setting is tortuous, the water channel assembly 2 cannot be formed as a whole, so the middle shell 22 and the left shell 23 are split and set, and the middle shell 22 and the left shell 23 are spliced ​​to form a first connecting flow section 223 extending in the front-to-back direction, which is used to connect to form a complete water inlet flow section 21c.

[0040] As shown in Figures 2 and 4 , a first groove 226 is formed on the inner side of the middle shell 22 facing the left shell 23, and a second groove 233 is formed on the side of the left shell 23 facing the middle shell 22. The first groove 226 and the second groove 233 together enclose a first connecting flow path section 223. This embodiment redirects the flow path of water flowing through the water tank inlet section 221 from the vertical direction to the front-to-back direction, rationalizing the arrangement of the water flow path and facilitating the connection between the corresponding components and the water path assembly 2.

[0041] As shown in Figures 5 and 6, the inlet flow section 21c includes a water tank inlet section 221, a first connecting flow section 223, and a water pump inlet flow section 231, which are sequentially connected. The filtered water flow section 42 includes a water pump outlet flow section 232, a water pump filter element connecting flow section 224, and a filter element inlet flow section 241, which are sequentially connected. The filtered return flow section 21d includes a filter element outlet flow section 242, a filter element connecting flow section 225, and a water tank outlet section 222, which are sequentially connected.

[0042] As shown in Figures 2 and 5 to 7, a water tank inlet section 221 is provided on the top surface of the middle shell 22, which is used to connect the water inlet pipe 10a of the water tank 210; a water tank outlet section 222 is also provided on the top surface of the middle shell 22. The water tank outlet section 222 is located in front of the water tank inlet section 221, and the water tank outlet section 222 is used to connect to the drinking water area of ​​the water tank 210. The middle shell 22 is also provided with a first connecting flow section 223, which is connected to the lower end of the water tank water inlet section 221 and extends in the front-to-back direction; and a water pump filter element connecting flow section 224 is also provided in the middle shell 22, and the water pump filter element connecting flow section 224 is provided below the first connecting flow section 223. The water pump filter element connecting flow section 224 is used to connect the water outlet end of the water pump 3 and the water inlet end of the filter device 400. A filter element connecting flow section 225 is also provided in the middle shell 22, and the filter element connecting flow section 225 is provided at the lower end of the water tank water outlet section 222, and is used to connect the water outlet end of the filter device 400 and the water tank water outlet section 222.

[0043] In this embodiment, the middle shell 22 is configured to be square. In other embodiments, it can also be configured to be other shapes to adapt to the internal structure of different pet water dispensers 200, which is not limited here.

[0044] As shown in FIG3 and FIG6 , the water tank water inlet section 221 and the water tank water outlet section 222 are located on the top surface of the middle shell 22 and are configured as a tubular structure in the up and down directions, with a plug-in space for accommodating the water inlet pipe 10a and the water outlet pipe 10b.

[0045] As shown in Figure 4 , the inlet of the filtered water flow section 42 is located on the outer side of the left shell 23, directly below the outlet of the inlet flow section 21c. In this embodiment, the inlet and outlet ports on the left shell 23 are aligned vertically. This design allows for easy docking and installation of the water pump 3 and waterway assembly 2, ensuring a precise and stable connection.

[0046] In addition, as shown in Figure 7, the water path assembly 2 also includes a first soft rubber hose and a second soft rubber hose. The outlet of the water inlet flow section 21c is connected to the water inlet end of the water pump 3 through the first soft rubber hose, and the water outlet end of the water pump 3 is connected to the filtered water flow section 42 through the second soft rubber hose. In this solution, the use of soft rubber hoses to connect the water pump 3 and the water path assembly 2 can achieve a shock absorption effect. Since the water pump 3 is prone to vibrate and make noise during operation, the use of soft rubber hoses can, on the one hand, ensure the sealing of the connection and the convenience of assembly. On the other hand, since the soft rubber hoses are soft in texture, they can absorb noise and vibration to a certain extent, so that the operation of the water pump 3 will not affect other components. In addition, when the positions of the relevant water inlets / outlets of the left shell 23 are aligned in the vertical direction, the lengths of the first soft rubber hose and the second soft rubber hose are the same, which can simplify accessories and improve assembly efficiency.

[0047] As shown in Figures 5 and 6, the left shell 23 is provided with a water pump inlet flow section 231, one end of which is connected to the water inlet of the water pump 3 and the other end is connected to the first connecting flow section 223. The left shell 23 is also provided with a water pump outlet flow section 232, one end of which is connected to the water outlet of the water pump 3 and the other end is connected to the water pump filter connecting flow section 224.

[0048] In this embodiment, the left shell 23 is configured as a square. In other embodiments, it can also be configured as other shapes to adapt to the internal structure of different pet water dispensers 200, which is not limited here.

[0049] In this embodiment, the water pump water inlet flow section 231 is a tubular structure protruding from the left shell 23. The tubular structure of the water pump water inlet flow section 231 is used to be plugged into the water inlet end of the water pump 3, which can not only ensure the tightness of the connection, making the flow path airtight and not prone to water leakage, but also improve the assembly efficiency during the production process.

[0050] In other embodiments, the tubular structure of the water pump inlet flow section 231 and the water inlet end of the water pump 3 may also be connected in other ways, such as by dispensing glue or using a seal to connect the two ends.

[0051] In this embodiment, the water pump outlet flow section 232 is also a protruding tubular structure, which is used to be plugged into the water outlet end of the water pump 3.

[0052] As shown in Figure 6, the outer side of the right shell 24 is provided with an outlet for the post-filtration return water flow section 21d, which is located directly below the inlet of the post-filtration return water flow section 21d. In this embodiment, the outlet of the post-filtration return water flow section 21d and the inlet of the post-filtration return water flow section 21d are aligned in the vertical direction. This design provides a consistent installation interface and a standardized connection method. In other words, the installer can easily connect the filter device 400 to the water channel assembly 2, and the disassembly operation is also simplified. Simply follow the same method and reverse the operation to disconnect.

[0053] In addition, the right shell 24 is provided with a filter element water inlet flow section 241, one end of the filter element water inlet flow section 241 is connected to the water pump filter element connecting flow section 224, and the other end is connected to the water inlet end of the filter device 400; the right shell 24 is also provided with a filter element water outlet flow section 242, one end of the filter element water outlet flow section 242 is connected to the water outlet end of the filter device 400, and the other end is connected to the filter element connecting flow section 225.

[0054] In this embodiment, as shown in Figure 3, a first sealing gasket 25 is disposed between the left shell 23 and the middle shell 22. This first sealing gasket 25 includes a first through-hole 251, which is located within the flow path of the third flow path 21a. This embodiment utilizes the provision of the first sealing gasket 25 to ensure a tight connection, reduce the possibility of water leakage, and ensure proper fluid transmission. The first through-hole 251 connects the first groove 226 and the second groove 233, and its dimensions match those of the first and second grooves 226 and 233. The first through-hole 251 serves to connect the water pump inlet flow path 231 with the first connecting flow path 223.

[0055] Since the filtered water supply flow section 42 includes a water pump outlet flow section 232, a water pump filter element connecting flow section 224, and a filter element inlet flow section 241 which are connected in sequence, the water pump outlet flow section 232 is formed in the left shell 23, the water pump filter element connecting flow section 224 is formed in the middle shell 22, and the filter element inlet flow section 241 is formed in the right shell 24, the first sealing gasket 25 is also provided with a second through hole 252, and the second through hole 252 is used to connect the water pump outlet flow section 232 and the water pump filter element connecting flow section 224, and the filtered water supply flow section 42 includes the second through hole 252.

[0056] In this embodiment, the first sealing gasket 25 is configured as a square sheet-like structure that matches the shape of the left shell 23 and the middle shell 22. In this embodiment, the sheet-like structure of the first sealing gasket 25 can be adapted to the flow path, achieving a good sealing effect while also speeding up assembly. In other embodiments, the first sealing gasket 25 can also be configured as a sealing ring to seal the connection between the water paths.

[0057] As shown in FIG4 to FIG6 , the second sealing gasket 26 is provided with a third through hole 261 , which is used to connect the filter element water inlet flow section 241 and the water pump filter element connecting flow section 224 .

[0059] In addition, the filtered return water flow section 21d includes a filter element outlet flow section 242, a filter element connecting flow section 225 and a water tank outlet section 222 connected in sequence. The filter element outlet flow section 242 is formed in the right shell 24, and the filter element connecting flow section 225 and the water tank outlet section 222 are formed in the middle shell 22.

[0060] The second sealing gasket 26 is configured as a square sheet structure that matches the shape of the right shell 24 and the middle shell 22. In this embodiment, the second sealing gasket 26 has a sheet structure that can match the flow path, not only achieving a good sealing effect, but also speeding up assembly.

[0061] In some other embodiments, the second sealing gasket 26 may also be configured as a sealing ring to seal the connection portion of the water channel.

[0062] As shown in Figures 5 and 6, the water inlet flow section 21c includes a water tank inlet section 221 and a water pump inlet flow section 231, which are connected in sequence. The water pump inlet flow section 231 is formed in the left shell 23, and the water tank inlet section 221 is formed in the middle shell 22. The two ends of the first connecting flow section 223 are connected to the water tank inlet section 221 and the water pump inlet flow section 231 respectively. The inlet of the water tank inlet section 221 is the inlet of the water inlet flow section 21c. The complete water inlet flow section 21c ensures a stable flow of water from the source.

[0063] As shown in Figures 3 and 4, the left shell 23, the middle shell 22, and the right shell 24 are fixedly connected by multiple screws 27.

[0065] In some other embodiments, the components of the housing 1 may be connected to each other by gluing or snapping. As a preferred embodiment of the present application, the advantages of using screws 27 to connect the left housing 23, the middle housing 22, and the right housing 24 are: the screws 27 are very tight, which can tighten the water channel assembly 2 and reduce the probability of water leakage of the water channel assembly 2. In addition, compared with other methods, the screw 27 fixed connection method is simpler to assemble, which can improve assembly efficiency.

[0066] In this embodiment, the inlet of the water inlet flow section 21c and the outlet of the filtered return water flow section 21d are aligned in the front-to-back direction, and the outlet of the water inlet flow section 21c and the inlet of the filtered return water flow section 21d are aligned in the left-to-right direction, so that the pipeline is symmetrical and regular, and the installation and disassembly of the corresponding components are relatively convenient. Since the filtered return water flow section 21d has a stroke in the up-down direction, the front-to-back direction, and the left-to-right direction at this time, and is arranged in a zigzag manner as a whole, the water channel assembly 2 cannot be formed as a whole, so the middle shell 22 and the right shell 24 are separated and arranged, and the middle shell 22 and the right shell 24 are spliced ​​to form a second connecting flow section extending in the front-to-back direction, which is used to connect to form a complete filtered return water flow section 21d.

[0067] In addition, in some other embodiments, multiple flow sections are formed in the water path assembly 2, and the multiple flow sections include independent water inlet flow sections 21c, filtered water supply flow sections 42, and filtered return water flow sections 21d; the water path assembly 2 includes a middle shell 22 and an upper shell (not shown) and a lower shell (not shown) assembled on both sides of the middle shell 22 (not shown), the water inlet flow section 21c is at least partially formed in the upper shell and the middle shell 22, the filtered water supply flow section 42 is at least partially formed in the lower shell, and the filtered return water flow section 21d is at least partially formed in the middle shell 22 and the upper shell. In this embodiment, the middle shell 22 has the functions of connection and support, and the water channel is assembled through the middle shell 22, the upper shell and the lower shell. This design simplifies the assembly process and improves the assembly efficiency of the water path assembly 2.

[0068] Specifically, the top surface of the upper shell is provided with an inlet of the water inlet flow section 21c and an outlet of the filtered return water flow section 21d, and the inlet of the water inlet flow section 21c and the outlet of the filtered return water flow section 21d are aligned in the front-to-back direction, and the two opposite outer side surfaces of the middle shell 22 are respectively provided with an outlet of the water inlet flow section 21c and an inlet of the filtered return water flow section 21d, and the outlet of the water inlet flow section 21c and the inlet of the filtered return water flow section 21d are aligned in the left-right direction. When the axis of the inlet of the filtered return water flow section 21d intersects with the axis of the outlet of the filtered return water flow section 21d, the upper shell and the middle shell 22 are spliced ​​to form a third connecting flow section extending in the front-to-back direction, and the water inlet flow section 21c includes a third connecting flow section (not shown). In this embodiment, the inlet of the water inlet flow section 21c and the outlet of the filtered return water flow section 21d are aligned in the front-to-back direction, and the outlet of the water inlet flow section 21c and the inlet of the filtered return water flow section 21d are aligned in the left-to-right direction, so that the pipeline is symmetrical and regular, and the installation and disassembly of the corresponding components are more convenient. Since the water inlet flow section 21c has a stroke in the up-down direction, the front-to-back direction, and the left-to-right direction at this time, and the overall setting is tortuous, the water channel assembly 2 cannot be formed as a whole, so the upper shell and the middle shell 22 are split and set, and the upper shell and the middle shell 22 are spliced ​​to form a third connecting flow section extending in the front-to-back direction, which is used to connect to form a complete water inlet flow section 21c.

[0069] In addition, based on similar technical concepts, when the axis of the inlet of the water inlet flow section 21c intersects with the axis of the outlet of the water inlet flow section 21c, the upper shell and the middle shell 22 are spliced ​​to form a fourth connecting flow section (not shown) extending in the front-to-back direction, and the filtered return water flow section 21d includes the fourth connecting flow section.

[0070] In this embodiment, as shown in Figures 8 and 11, the filter device 400 includes a device shell 4 and a soft rubber seat 43, a filter flow channel 41 is formed in the device shell 4, and the filter flow channel 41 includes an inlet channel opening 41a and an outlet channel opening 41b facing the same side; the soft rubber seat 43 is formed with an inlet 432 and a water outlet 431, the soft rubber seat 43 is connected to the device shell 4, the water inlet 432 is communicated with the inlet channel opening 41a, and the water outlet 431 is communicated with the outlet channel opening 41b, the water inlet 432 is the water inlet end of the filter device 400, and the water outlet 431 is the water outlet end of the filter device 400. The side wall of the housing 1 is provided with a side-mounted opening 1e, through which the filter device 400 is installed into the housing 1. When the user needs to install the filter device 400 in the pet water dispenser 200, they only need to hold the device housing 4 and insert the soft rubber seat 43 into the pipe of the pet water dispenser 200 to install the filter device 400 into the pet water dispenser 200. The same convenient method also applies to the case where the user needs to remove the filter device 400 from the pet water dispenser 200. The user only needs to hold the device housing 4 and pull the soft rubber seat 43 of the filter device 400 out of the pipe of the pet water dispenser 200. The filter device 400 of the present application allows the user to easily complete the removal and replacement of the filter device 400.

[0071] Those skilled in the art will appreciate that the soft rubber base 43 is elastic, adapting to various shapes and surfaces while also being able to bend and stretch without breaking. In this embodiment, the pipe of the pet water dispenser 200 can be inserted into the soft rubber base 43 of the filter device 400 to establish water communication between the pipe of the pet water dispenser 200 and the filter device 400.

[0072] In this embodiment, the device housing 4 is provided with a mounting portion 4d, to which the soft rubber seat 43 is connected. An annular mounting protrusion is provided on one of the inner wall of the mounting portion 4d and the outer wall of the soft rubber seat 43, and an annular mounting groove is provided on the other of the inner wall of the mounting portion 4d and the outer wall of the soft rubber seat 43. This embodiment can enhance the stability of the connection between the device housing 4 and the soft rubber seat 43.

[0073] As shown in FIG8 , a filter element assembly 44 is installed within the device housing 4 . The filter element assembly 44 includes a filter element 441 and a support frame 45 . The filter element 441 is installed on the support frame 45 . The support frame 45 and the inner wall surface of the device housing 4 together form a filter channel 41 . When assembling the filter device 400 of this embodiment, the factory installs the filter element 441 on the support frame 45 , and then installs the support frame 45 into the device housing 4 . This simplifies the assembly process and improves production efficiency.

[0074] In other embodiments, the device shell 4 is provided with a water inlet pipe (not shown) and a drain pipe (not shown), the water inlet pipe is connected to the water inlet channel port 41a, and the drain pipe is connected to the water outlet channel port 41b, and the soft rubber seat 43 is covered on the inner circumferential wall of the water inlet pipe to form a water inlet 432, and the soft rubber seat 43 is covered on the inner circumferential wall of the water outlet pipe 10b to form a water outlet 431. Since the inner walls of the water inlet 432 and the water outlet 431 are provided with a soft rubber seat 43, when the user needs to install the filter device 400 on the pet water dispenser 200, he only needs to hold the device shell 4 and then push the soft rubber seat 43 into the pipe of the pet water dispenser 200 to install the filter device 400 into the pet water dispenser 200; the same convenient method is also applicable to the situation where the user needs to remove the filter device 400 from the pet water dispenser 200. The user only needs to hold the device shell 4 and pull out the soft rubber seat 43 of the filter device 400 from the pipe of the pet water dispenser 200.

[0075] As shown in FIG9 , the filtration channel 41 includes an inlet channel section 411 and an outlet channel section 412 that are interconnected. The inlet channel section 411 is directly connected to the water inlet 432, and the outlet channel section 412 is directly connected to the water outlet 431. This embodiment can reduce pressure loss during water flow, improve efficiency, and increase the reliability of the filtration device 400.

[0076] As shown in Figure 9, the support frame 45 includes a surrounding plate 451 and a first partition plate 452. The first partition plate 452 is arranged at intervals in the space enclosed by the surrounding plate 451. The surrounding plate 451 encloses an installation space that passes through from left to right. The first partition plate 452 is arranged in the installation space. The opposite ends of the first partition plate 452 are connected to the inner wall surface of the surrounding plate 451 to form a first channel 413 and a second channel 414 arranged in the up and down directions. The first channel 413 and the inner wall surface of the device shell 4 jointly form the water outlet flow channel section 412, and the second channel 414 and the inner wall surface of the device shell 4 jointly form the water inlet flow channel section 411. The end of the first partition plate 452 away from the water outlet 431 and the inner wall surface of the device shell 4 jointly form a connecting port 415. The water inlet flow channel section 411 is connected to the water outlet flow channel section 412 through the connecting port 415.

[0077] As shown in Figure 9, the water inlet channel section 411 includes a first water inlet channel section 4111 and a second water inlet channel section 4112 connected in parallel between the water inlet channel opening 41a and the communication opening 415. In this embodiment, if either the first water inlet channel section 4111 or the second water inlet channel section 4112 is blocked, water can be transported to the water outlet channel section 412 through the other one.

[0078] As shown in Figures 9 and 10, water flows from the water inlet 432 into the water inlet channel port 41a of the filter channel 41, and is then diverted to the first water inlet channel section 4111 and the second water inlet channel section 4112. When the water flows through the first water inlet channel section 4111, it is purified by the hollow ultrafiltration filament 445. When the water flows through the second water inlet channel section 4112, it is filtered by the filter sponge 442. The water passes through the ion exchange fiber 444 upward through the connecting port 415 and enters the water outlet channel section 412. When the water passes through the water outlet channel section 412, it is purified by the activated carbon bag 443, and then flows out from the water outlet 431 through the water outlet channel port 41b of the filter channel 41.

[0079] As shown in Figure 9, the second water inlet flow channel section 4112 is arranged beside the first water inlet flow channel section 4111. Specifically, the support frame 45 also includes a second partition 453, which is arranged in the second channel 414 and divides the second channel 414 into a main channel and a secondary channel spaced apart in the vertical direction. The main channel and the inner wall surface of the device housing 4 together form the first water inlet flow channel section 4111, and the secondary channel and the inner wall surface of the device housing 4 together form the second water inlet flow channel section 4112. In this embodiment, the first water inlet flow channel section 4111, the second water inlet flow channel section 4112, and the water outlet flow channel section 412 are formed by the support frame 45 and the device housing 4, which reduces design complexity and also provides more convenient and quick assembly.

[0080] As shown in FIG. 9 , the filter element 441 includes a hollow ultrafiltration filament 445 , which is disposed in the first water inlet flow channel section 4111 .

[0081] Those skilled in the art will appreciate that the hollow ultrafiltration filament 445 is composed of hollow fibers and has a microporous structure, which can effectively filter out suspended matter, particles, microorganisms, and certain soluble substances. In other embodiments, the filter element 441 can be an ultrafiltration filter element, a nanofiltration filter element, or other types of microfiltration filter elements.

[0082] As shown in FIG9 , the filter element 441 includes a filter sponge 442 disposed within the second water inlet channel section 4112. A first through-hole 4112a is formed within the second water inlet channel section 4112. The filter sponge 442 is disposed within the second water inlet channel section 4112, with the water inlet side of the filter sponge 442 blocking the first through-hole 4112a. The water outlet side of the filter sponge 442 is connected to the inner wall surface of the device housing 4. In this embodiment, water flows into the first water inlet channel section 4111 and the second water inlet channel section 4112 through the water inlet channel opening 41a. The filter sponge 442 not only filters the water flowing through the second water inlet channel section 4112, but also increases the pressure within the second water inlet channel section 4112, causing more water to flow into the first water inlet channel section 4111.

[0083] If, as shown in FIG9 , the support frame 45 further includes a second partition 453, the second partition 453 is disposed within the second channel 414 and divides the second channel 414 into a main channel and a secondary channel spaced apart in the vertical direction, the main channel and the inner wall surface of the device housing 4 together form a first water inlet flow channel section 4111, and the secondary channel and the inner wall surface of the device housing 4 together form a second water inlet flow channel section 4112. In this embodiment, water flows into the first water inlet flow channel section 4111 and the second water inlet flow channel section 4112 through the water inlet channel opening 41a. Since the first water inlet flow channel section 4111 and the second water inlet flow channel section 4112 are generally disposed in the vertical direction, water with more impurities tends to flow into the second water inlet flow channel section 4112 and be filtered by the filter sponge 442.

[0084] It should be noted that the width of the first water inlet channel section 4111 is approximately 2.5 times the width of the second water inlet channel section 4112. In this embodiment, the width of the first water inlet channel section 4111 is approximately 130 mm, and the width of the second water inlet channel section 4112 is designed to be approximately 50 mm. The height from the centerline of the water inlet 432 to the centerline of the water outlet 431 is approximately 60 mm. The height difference is very small. When the water source passes through the diaphragm water pump 3, the diaphragm water pump 3 provides power to the water, allowing the water source to rush into the water inlet 432 in the filter device 400, be filtered, and then be flushed out through the water outlet 431.

[0085] As shown in Figure 2, filter element 441 also includes activated carbon bag 443 and ion exchange fiber 444 within outlet channel 412 to further purify the water. After passing through ion exchange fiber 444 and activated carbon bag 443, the water undergoes a double purification process, resulting in a purer and healthier water, making it safer for pets to drink.

[0086] As shown in FIG9 , the water outlet channel section 412 is formed with a second through-hole 412a. The filter element assembly 44 also includes a valve stem 46 and a pressure spring 47 disposed in the water outlet channel section 412. One end of the pressure spring 47 is fixedly connected to the support frame 45, and the other end of the pressure spring 47 is connected to the valve stem 46. The pressure spring 47 drives the valve stem 46 to move relative to the second through-hole 412a to close the second through-hole 412a. When the user disassembles and removes the filter device 400 from the pet water dispenser 200, a certain amount of water will be stored in the filter device 400. The pressure spring 47 in the water outlet channel section 412 drives the valve stem 46 to move relative to the second through-hole 412a to close the second through-hole 412a, effectively preventing the remaining water in the filter device 400 from flowing out.

[0087] As shown in FIG. 9 , the second sealing ring 48 is sleeved on the valve core rod 46 to seal the second through hole 412 a .

[0088] As shown in Figure 9, the device housing 4 of this embodiment includes a first housing 4a and a second housing 4b. The first housing 4a is connected to a soft rubber seat 43. A first chamber is formed in the first housing 4a, which is open toward the second housing 4b. A second chamber is formed in the second housing 4b, which is open toward the first housing 4a. The first and second chambers are opposite each other and, when combined, form a housing for the filter element assembly 44. When assembling the filter device 400 of this embodiment in the factory, the filter element 441 is mounted on the support frame 45, which is then installed and placed in the first chamber of the first housing 4a. The second housing 4b is then capped on the first housing 4a. This simplifies the assembly process and improves production efficiency.

[0089] As shown in Figure 9 , a handle 4c is provided on the outer wall of the second housing 4b. This embodiment provides convenience for users to remove or install the filter device 400 from the pet water dispenser 200.

[0090] As shown in FIG. 9 , the ion exchange fiber 444 is housed in the second chamber.

[0091] 8 and 9 , a first sealing ring is provided between the outer wall of the support frame 45 of the filter element assembly 44 and the inner wall of the device housing 4. The filter device 400 of this embodiment has a compact structure and stable performance.

[0092] In this embodiment, as shown in FIG1 , the water treatment mechanism 100 includes a control assembly 5, which includes a control panel 51, a key panel 52, and a connecting circuit. The control panel 51 is mounted in the first chamber, and the key panel 52 is mounted in the second chamber. The partition plate 1a is formed with a through hole for passing a wire. One end of the connecting circuit is electrically connected to the key panel 52, and the other end of the connecting circuit passes through the through hole and enters the first chamber to be electrically connected to the control panel 51. The key panel 52 is electrically connected to the water pump 3. Thus, when the water in the water tank 210 needs to be treated, the button on the key panel 52 is triggered, and the electrical signal is transmitted to the control panel 51 through the connecting circuit. Then, under the action of the control panel 51, the start and stop of the water pump 3 are controlled.

[0093] In this embodiment, as shown in FIG1 , the side wall of the second chamber is provided with an installation through hole, and the buttons of the key panel 52 can be exposed in the installation through hole. Thus, the buttons on the key panel 52 are triggered to turn on and off the water pump 3 to realize the shutdown control of the water treatment mechanism 100.

[0094] As shown in Figure 1, the housing 1 comprises a cover plate 12, an upper housing 13 with a top opening, and a lower housing 14 with a top opening. The cover plate 12 covers the top opening of the upper housing 13 to form a first chamber. The bottom wall of the upper housing 13 serves as a partition plate 1a, and the bottom wall of the upper housing 13 covers the top opening of the lower housing 14 to form a second chamber. The housing 1 is configured as a split structure, allowing the mounting base 101 and control panel 51 to be installed in the upper housing 13 while the waterway assembly 2, water pump 3, filter device 400, and keypad are installed in the lower housing 14. The assembled upper and lower parts can then be assembled. Through the split design of the shell 1, the water treatment mechanism 100 can be assembled in a manner of subassembly and reassembly to reduce the difficulty of assembling each part, realize the rapid assembly of the water treatment mechanism 100, and improve the assembly efficiency. The outer side of the water pump 3 is coated with shock-absorbing foam, and the shock-absorbing foam is provided to reduce the vibration of the water pump 3 during operation and reduce the noise generated by the operation of the water treatment mechanism 100. The water pump 3 is a diaphragm water pump 3, and the water pump 3 adopts a diaphragm water pump 3 with strong self-priming ability so as to better extract the water in the water tank 210.

[0095] In this embodiment, as shown in Figures 1 and 12, the water treatment mechanism 100 also includes a positioning seat 6 accommodated in the second chamber, the positioning seat 6 is installed on the partition plate 1a, the water pump 3 and the waterway assembly 2 are installed on the positioning seat 6, the lower end surface of the positioning seat 6 is concave to form a first accommodating groove 61, and the side walls of the first accommodating groove 61 pass through the left and right sides of the positioning seat 6. The water treatment mechanism 100 also includes a bearing seat 7 connected and fixed to the positioning seat 6, the bearing seat 7 is located below the water pump 3, and the upper end surface of the bearing seat 7 is concave to form a second accommodating groove 71, and the side walls of the second accommodating groove 71 pass through the left and right sides of the positioning seat 6. The second accommodating groove 71 and the first accommodating groove 61 together enclose a accommodating channel, and the water pump 3 is installed in the accommodating channel. The positioning seat 6 and the bearing seat 7 together form an accommodating channel for the installation of the water pump 3, thereby improving the installation stability of the water pump 3.

[0096] As shown in FIG. 13 to FIG. 18 , it is an embodiment of the water treatment mechanism provided by the present application.

[0097] The present application also proposes a pet drinking fountain 200, as shown in FIG13, the pet drinking fountain 200 includes a water tank 210, a water pumping pipe 15 and a water treatment mechanism 100. The specific structure of the water treatment mechanism 100 refers to the above embodiment. The specific structure of the water treatment mechanism 100 is shown in FIG1 to FIG2. The water tank 210 is detachably connected to the water treatment mechanism 100. The water tank 210 includes a water storage tank 211 and a drinking trough 220. The water storage tank 211 defines The pet water dispenser 200 has a water storage chamber 211a with a top opening. This chamber serves as the water storage area of ​​the water tank 210. The drinking trough 220 includes a trough body 2201 and an extension 2202. Extension 2202 extends from the circumferential edge of the trough body 2201 away from the trough body 2201. The trough body 2201 serves as the drinking area of ​​the water tank 210. A first flow path connects to the water storage chamber 211a via a pumping pipe 15, while a second flow path 101b connects to the trough body 2201. The pet water dispenser 200 utilizes a detachable connection between the water tank 210 and the water treatment mechanism 100. Combined with the design of the water treatment mechanism 100, the pet water dispenser 200 provides excellent water quality management while occupying a small space.

[0098] Specifically, in this embodiment, as shown in Figures 13 to 16, the housing 1 includes a pressing portion 112 and a limiting portion. The pressing portion 112 abuts against the edge 2202 of the water trough 220 to compress the water tank 210, while the limiting portion cooperates with the sidewall edge of the water storage tank 211 and / or the water trough 220 to limit the displacement of the water tank 210. The pressing portion 112 is connected to the edge 2202 of the water trough 220, and the limiting portion cooperates with the sidewall edge of the water storage tank 211 and / or the water trough 220 to form a tight connection between the water tank 210 and the water treatment mechanism 100, providing a high degree of stability, effectively preventing separation of the water tank 210 and the water treatment mechanism 100, and ensuring the long-term use of the pet water dispenser 200.

[0099] In this embodiment, as shown in Figures 15 and 16, the shell 1 is formed with a card slot 1b with an opening facing downward, and the side wall edge of the water tank 211 and / or the drinking trough 220 is suitable for extending into the card slot 1b to snap fit with the card slot 1b. The shell 1 is provided with an abutment block 1d protruding outward on one side facing the water tank 211, and the abutment block 1d abuts against the side wall of the water tank 211. The limiting portion includes the card slot 1b.

[0100] In the embodiment disclosed in Figure 13, the drinking trough 220 is integrally embedded in the water tank 211, specifically: the first step portion 211b of the inner wall of the water tank 211, the extension 2202 of the drinking trough 220 is detachably mounted on the first step portion 211b, at this time, the top of the water tank 211 is higher than the top of the drinking trough 220, the side wall edge of the water tank 211 is exposed and extends into the card slot 1b to snap fit with the card slot 1b. Those skilled in the art will appreciate that there are at least the following methods: Method 1, the edge 2202 of the drinking trough 220 is provided with a hanging groove (not shown), and the side wall edge of the water storage tank 211 extends into the hanging groove of the drinking trough 220. At this time, the top of the drinking trough 220 is higher than the top of the water storage tank 211, and the side wall edge of the drinking trough 220 is exposed and extends into the card slot 1b to snap fit with the card slot 1b; Method 2, the inner side wall of the drinking trough 220 and the outer side wall of the water storage tank 211 constitute opposite side walls connected to the card slot 1b, and the side walls extend into the card slot 1b to snap fit with the card slot 1b.

[0101] In the technical solution of the present application, when a pet kicks the pet water dispenser 200, the side wall edges of the water tank 211 and / or the water trough 220 extend into the card slot 1b of the shell 1 of the chassis, and the snap-fit ​​design enables the water tank 210 and the water treatment mechanism 100 to be stably and firmly connected. At the same time, since the water tank 211 abuts against the outer protrusion of the shell 1 to form an abutment block 1d, the shaking and loosening of the pet water dispenser 200 caused by external force can be reduced, thereby reducing the risk of the pet water dispenser 200 being pushed over.

[0102] In one embodiment, the slot wall of the card slot 1b is provided with an elastic protrusion 1c, and the side wall edge of the water tank 211 abuts against the elastic protrusion 1c. In this way, the elastic deformation of the elastic protrusion 1c can facilitate the disassembly and assembly of the water tank 210 and the water treatment mechanism 100.

[0103] It is understood that in FIG13 , the sidewall edge of the water tank 211 is exposed to mate with the slot 1b, and the slot 1b has elastic projections 1c disposed on its walls for abutting the sidewall edge of the water tank 211. It is also understood by those skilled in the art that when the sidewall edge of the water trough 220 is exposed to mate with the slot 1b, the slot 1b has elastic projections 1c disposed on its walls for abutting the sidewall edge of the water trough 220. When the inner side wall of the drinking trough 220 and the outer side wall of the water storage tank 211 constitute two opposite side walls connected to the card slot 1b, at this time, only one slot wall of the card slot 1b is provided with an elastic protrusion 1c, and the elastic protrusion 1c abuts against the edge of the side wall of the water storage tank 211, or the elastic protrusion 1c abuts against the edge of the side wall of the drinking trough 220; or, at this time, both slot walls of the card slot 1b are provided with elastic protrusions 1c, and the elastic protrusions 1c abut against the edge of the side wall of the water storage tank 211 and the edge of the side wall of the drinking trough 220 respectively.

[0104] As shown in Figures 13 and 17 , the inner sidewall of the water tank 211 has a first step 211b. The edge 2202 of the drinking trough 220 is removably mounted on the first step 211b, allowing the drinking trough 220 to be inserted into the water storage chamber 211a. The sidewall edge of the water tank 211 extends into the retaining groove 1b, securing it to the retaining groove 1b. This design allows the drinking trough 220 to be mounted within the water storage chamber 211a, making it easy to install and remove for cleaning.

[0105] In one embodiment, the abutment block 1d is elastic, allowing it to elastically abut against the water tank 211. This design can improve the strength and pressure resistance of the pet water dispenser 200. In other embodiments, the cross-section of the abutment block 1d gradually increases as it approaches the outer wall of the housing 1. This provides the water tank 211 with an appropriate thrust, effectively preventing rupture or deformation caused by external pressure.

[0106] In one embodiment, the slot wall of the card slot 1b is provided with an elastic protrusion 1c, and the side wall edge of the water tank 211 abuts against the elastic protrusion 1c. In this way, the elastic deformation of the elastic protrusion 1c can facilitate the disassembly and assembly of the water tank 210 and the water treatment mechanism 100.

[0107] It is understood that in FIG13 , the sidewall edge of the water tank 211 is exposed to mate with the slot 1b, and the slot 1b has elastic projections 1c disposed on its walls for abutting the sidewall edge of the water tank 211. It is also understood by those skilled in the art that when the sidewall edge of the water trough 220 is exposed to mate with the slot 1b, the slot 1b has elastic projections 1c disposed on its walls for abutting the sidewall edge of the water trough 220. When the inner side wall of the drinking trough 220 and the outer side wall of the water storage tank 211 constitute two opposite side walls connected to the card slot 1b, at this time, only one slot wall of the card slot 1b is provided with an elastic protrusion 1c, and the elastic protrusion 1c abuts against the edge of the side wall of the water storage tank 211, or the elastic protrusion 1c abuts against the edge of the side wall of the drinking trough 220; or, at this time, both slot walls of the card slot 1b are provided with elastic protrusions 1c, and the elastic protrusions 1c abut against the edge of the side wall of the water storage tank 211 and the edge of the side wall of the drinking trough 220 respectively.

[0108] As shown in Figures 13 and 17 , the inner sidewall of the water tank 211 has a first step 211b. The edge 2202 of the drinking trough 220 is removably mounted on the first step 211b, allowing the drinking trough 220 to be inserted into the water storage chamber 211a. The sidewall edge of the water tank 211 extends into the retaining groove 1b, securing it to the retaining groove 1b. This design allows the drinking trough 220 to be mounted within the water storage chamber 211a, making it easy to install and remove for cleaning.

[0109] In one embodiment, the abutment block 1d is elastic, allowing it to elastically abut against the water tank 211. This design can improve the strength and pressure resistance of the pet water dispenser 200. In other embodiments, the cross-section of the abutment block 1d gradually increases as it approaches the outer wall of the housing 1. This provides the water tank 211 with an appropriate thrust, effectively preventing rupture or deformation caused by external pressure.

[0110] As shown in Figure 13, the housing 1 includes a housing body 11 and a housing boss 111. The housing boss 111 is disposed on the housing body 11 and protrudes outward from the housing body 11. The lower end surface of the housing boss 111 is a press-fit portion 112. The housing boss 111 faces the inner peripheral wall of the housing body 11 and forms a downward-opening slot 1b with the housing body 11. In this embodiment of the pet water dispenser 200, the water treatment mechanism 100 is connected to the extension 2202 of the water trough 220 mounted on the top of the water storage tank 211 via the press-fit portion 112. At the same time, the water treatment mechanism 100 is limited by the side wall of the water storage tank 211 and / or the water trough 220 via the slot 1b, forming a tight connection between the water treatment mechanism 100 and the water tank 210. This provides a high degree of stability, effectively preventing separation between the water tank 210 and the water treatment mechanism 100, and ensuring the long-term use of the pet water dispenser 200.

[0111] As shown in Figure 2, the wall of the trough body 2201 is provided with an overflow hole 2201a, which is connected to the water storage chamber 211a. The overflow hole 2201a is provided in the wall of the trough body 2201 to allow water in the drinking trough 220 to flow into the water storage chamber 211a, thereby preventing excessive water from overflowing from the trough body 2201.

[0112] As shown in Figures 13 and 14, the water tank 210 also includes a primary filter layer 230 positioned corresponding to the overflow hole 2201a. The primary filter layer 230 includes a filter support 2301 and a filter element 2302. The filter element 2302 is positioned on the filter support 2301 and located on the outlet side of the overflow hole 2201a. The filter support 2301 is formed with a filter hole 2301a, which is located on the outlet side of the filter element 2302. The filter hole 2301a is connected to the water storage chamber 211a. In this embodiment, water from the drinking trough 220 flows through the overflow hole 2201a, falls on the filter element 2302, and is filtered by the filter element 2302 before entering the water storage chamber 211a through the filter hole 2301a. The pet water dispenser 200 of this embodiment can achieve preliminary filtration with the help of the primary filter layer 2300, for example, to filter out pet hair or food residue.

[0113] As shown in Figures 17 and 18, filter support 2301 includes a bottom plate 23012 and two side plates 23011. The two side plates 23011 are connected to both ends of the bottom plate 23012 to form a receiving space together with the bottom plate 23012. The inner sidewalls of the side plates 23011 have a second step portion, and the filter element 2302 is disposed in the receiving space via the second step portion. In this way, this design allows for stable installation of the filter element 2302.

[0114] As shown in Figures 17 and 18, the inner sidewall of the side panel 23011 has a hooking portion 23011a that engages with the overflow hole 2201a, allowing the filter bracket 2301 to be detachably connected to the water trough 220. To replace or clean the filter element 2302, the user first removes the primary filter layer 230 and the water trough 220 from the water storage chamber 211a, then removes the primary filter layer 230 from the water trough 220. The user then removes the filter element 2302 from the accommodating space for cleaning or replacement. After placing the clean filter element 2302 into the accommodating space, the user then installs the primary filter layer 230 on the water trough 220, and then places both filter elements into the water storage chamber 211a. This design improves the convenience of replacing or cleaning the filter element 2302.

[0115] As shown in Figures 17 and 18 , the bottom plate 23012 is angled downward toward the inner wall of the water tank 211. A filter hole 2301a is defined in the side plate 23011 near the water tank 211. In this embodiment of the pet drinking fountain 200, water filtered by the filter element 2302 falls onto the bottom plate 23012 and then flows out of the filter hole 2301a near the inner wall of the water tank 211 along the inclined surface. This effectively reduces the noise generated by the water flow, providing a quiet and comfortable environment for pets and users.

[0116] As shown in Figures 13 and 17 , a water extraction hole 2202a is provided along the edge 2202 of the drinking trough 220. The water treatment mechanism 100 includes a water extraction pipe 15, a water inlet pipe 10a (not shown), and a water outlet pipe 10b. One end of the water extraction pipe 15 is connected to the water inlet pipe 10a, and the other end of the water extraction pipe 15 passes through the water extraction hole 2202a and is connected to the water storage chamber 211a. Water in the water storage chamber 211a flows through the water extraction pipe 15 into the water inlet pipe 10a and out of the water outlet pipe 10b to the drinking trough 220. In this way, water in the drinking trough 220 can flow into the water storage chamber 211a and, after being filtered, flow back into the drinking trough 220, thereby allowing the water in the pet drinking fountain 200 to circulate.

[0117] As shown in Figures 1 and 17, water treatment mechanism 100 includes a high-level filtration layer, which includes a filter device 400. Filter device 400 is disposed within housing 1 and includes housing 4 and a filter channel 41 formed within housing 4. Filter channel 41 is provided with ultrafiltration, microfiltration, or nanofiltration. Water from water storage chamber 211a flows through inlet pipe 10a into filter device 400, is filtered by filter device 400, and then flows out of outlet pipe 10b. Thus, water flowing back into housing 1 is filtered by filter device 400, resulting in purer water that pets can drink with greater peace of mind.

[0118] As shown in Figure 17, the water treatment mechanism 100 includes a secondary filter layer 151, and the secondary filter layer 151 includes a filter screen. The filter screen is arranged at the water inlet end of the water pump 15. In this way, the water in the water storage chamber 211a can be filtered twice to improve the cleanliness, while preventing foreign matter from flowing into the water pump 3 and causing the water pump 3 to be blocked.

[0119] In the embodiment shown in FIG1 , the water pump 3 is disposed within the housing 1 . Those skilled in the art will appreciate that there is at least one alternative embodiment: the water pump 3 is disposed within the water storage tank 211 . In this embodiment, the water inlet of the water pump 3 communicates with the water storage chamber 211a , and the water outlet of the water pump 3 communicates with the water pumping pipe 15 , which draws water into the water treatment mechanism 100 . This embodiment is common in the art and will not be described in detail here.

[0120] As shown in FIG1 , a control board 51 is provided in the housing 1 , and the control board 51 is electrically connected to the water pump 3 , so that the start and stop of the water pump 3 are controlled by the control board 51 .

[0121] In one embodiment, the water pump 3 is a diaphragm water pump 3 , which has a strong self-priming ability so as to better extract water from the water storage chamber 211 a .

[0122] In this embodiment, the water tank 211 is made of stainless steel. The water tank 211 of pet water dispensers 200 currently on the market is typically made of plastic. However, long-term storage of water in plastic can lead to the formation of fine scale, dust, or other deposits on the inner walls of the water tank 211. These deposits can, under certain conditions, pose a risk of microbial contamination of the water. Cleaning the inner walls of a plastic water tank 211 also requires appropriate cleaning agents and tools. A stainless steel water tank 211 can avoid these issues.

[0123] In this embodiment, the drinking trough 220 is made of stainless steel. Since the stainless steel container is manufactured through a stamping process, the design of the edge 2202 of the drinking trough 220 and the edge of the water storage tank 211 having a folded edge can increase the rigidity of the container and prevent the safety hazards caused by sharp edges.

[0124] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made based on the contents of the present application specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present application.
