When the pet uses the water in the water feeding box 730 to cause the water level in the water feeding box 730 to drop, the water level in the water receiving box 722 drops due to the communication between the water feeding box 730 and the water receiving box 722. The water level in the water receiving box 722 drops, the buoyancy force borne by the floating part 7231 of the adjusting member 723 is reduced, the floating part 7231 drops downwards under the action of self gravity, the floating part 7231 drives the first connecting part 7232 to rotate relative to the water pipe, the first connecting part 7232 drives the blocking part 7233 to be far away from the second end of the connecting pipe 721, the water in the water storage barrel 710 can enter the connecting pipe 721 through the first end of the connecting pipe 721 and enter the water receiving box 722 from the second end of the connecting pipe 721, so that the water level in the water receiving box 722 rises, and the water level in the water feeding box 730 rises to supplement water in the water feeding box 730. When the water levels in the water feeding box 730 and the water receiving box 722 rise, the buoyancy force exerted on the floating portion 7231 of the adjusting member 723 is increased, the floating portion 7231 rises upwards against the gravity thereof, the floating portion 7231 drives the first connecting portion 7232 to reversely rotate relative to the water pipe, and the first connecting portion 7232 drives the blocking portion 7233 to be close to the second end of the connecting pipe 721. When the water in the water feeding box 730 and the water receiving box 722 rises to a certain height, the blocking portion 7233 contacts with the second end of the connecting pipe 721 to block the connecting pipe 721, so that the water in the water storage tank 710 and the connecting pipe 721 stops being injected into the water receiving box 722, and the water level in the water feeding box 730 is automatically adjusted.

Compared with the prior art that the water level of the water feeding box 730 is adjusted by arranging the liquid level sensor in the water feeding box 730 or the water receiving box 722 and arranging the electromagnetic valve on the connecting pipe 721, the water feeding device 700 of the embodiment of the application does not need to arrange the liquid level sensor and the electromagnetic valve, and the part cost of the water feeding device 700 is reduced. In addition, the water feeding device 700 of the embodiment of the application can realize automatic adjustment of the water level in the water feeding box 730 without power on control, and the use cost of the water feeding device 700 is reduced.

For example, referring to fig. 23 and 24, the water level adjustment mechanism 720 may further include a rotation shaft 724, and the rotation shaft 724 is horizontally installed in the water receiving box 722. The first connecting portion 7232 is provided with the first connecting hole 7234, and the first connecting hole 7234 can be sleeved on the rotating shaft 724 and in clearance fit with the rotating shaft 724, so that the first connecting portion 7232 can be rotationally connected with the water receiving box 722 through the first connecting hole 7234 and the first rotating shaft 724 which are mutually sleeved, the connecting structure between the first connecting portion 7232 and the water receiving box 722 is simplified, convenience in assembling the adjusting piece 723 and the water receiving box 722 is improved, and the assembling efficiency of the feeding device 600 is improved.

In some implementations of embodiments of the present application, the rotational shaft 724 may be directly attached to the sidewall of the water-receiving box 722.

In other implementations of the embodiments of the present application, referring to fig. 18, 22, 23 and 24, the water level adjusting mechanism 720 may further include a mounting bracket 725, where the mounting bracket 725 includes two first connection plates 7251, the two first connection plates 7251 are respectively located at two sides of the first connection portion 7232 and are both connected to a side wall of the water receiving box 722, and a rotation shaft 724 is disposed at one side of the two connection plates opposite to each other. So set up, first connecting portion 7232 accessible two axis of rotation 724 are rotated with two first connecting plates 7251 and are connected, have improved the stationarity when first connecting portion 7232 rotates, avoid leading to the functional failure of water level adjustment because of first connecting portion 7232 rotates unstably.

Illustratively, the sidewall of the water receiving box 722 opposite to the first connection plate 7251 may be provided with a fixing portion 7221, and the top side of the fixing portion 7221 is provided with a second connection hole. The water level adjusting mechanism 720 further includes a fixing plate 726 and a connecting member 727, one end of the fixing plate 726 is connected to the first connecting plate 7251, the fixing plate 726 is provided with a third connecting hole 7261, and the third connecting hole 7261 is opposite to the second connecting hole. The connecting piece 727 is inserted into the third connecting hole 7261 and the second connecting hole. When the first connecting plate 7251 is connected to the side wall of the water receiving box 722, the third connecting hole 7261 of the fixing member can be opposite to the second connecting hole on the top side of the fixing portion 7221, then the connecting member 727 is inserted into the third connecting hole 7261 and the second connecting hole along the axial direction of the third connecting hole 7261 and the second connecting hole, and an operation space for assembling the connecting member 727 is located above the water receiving box 722 and cannot interfere with other parts in the water receiving box 722, so that the first connecting plate 7251 is convenient to assemble. In addition, since the first connecting plate 7251 is connected to the fixing portion 7221 on the side wall of the water receiving box 722, no hole is required on the side wall of the water receiving box 722, so that the water leakage of the water receiving box 722 is avoided and the water level adjusting function is prevented from being affected.

For example, referring to fig. 22, the fixing portion 7221 may be provided with a first positioning surface 7222 and a second positioning surface 7223, the first positioning surface 7222 being located at a top end of the fixing portion 7221, the first positioning surface 7222 being provided with a second connection hole. The second positioning surface 7223 is located at a side of the fixing portion 7221 facing the first connecting plate 7251, and forms an included angle with the first positioning surface 7222. The fixing plate 726 includes a first sub-fixing plate 7262 and a second sub-fixing plate 7263 connected, the first sub-fixing plate 7262 is abutted with the first positioning surface, and the first sub-fixing plate 7262 is provided with a third connection hole 7261. The second sub-fixing plate 7263 abuts against the second positioning surface. In the process of connecting the first connection plate 7251 with the water receiving box 722, the first positioning surface 7222 can position the first sub-fixing plate 7262, the second positioning surface 7223 can position the second sub-fixing plate 7263, alignment between the third connection hole 7261 and the second connection hole is facilitated, and connection convenience of the first connection piece 727 and the water receiving box 722 is improved.

The mounting bracket 725 may further include a second connection plate 7252 and a fixing tube 7253, the second connection plate 7252 being perpendicular to the first connection plates 7251 and connected to the two first connection plates 7251. The fixing tube 7253 is inserted into the second connection plate 7252, one end of the fixing tube 7253 communicates with the second end of the connection tube 721, and the other end of the fixing tube 7253 faces the blocking portion 7233. Since the connection pipe 721 is generally a hose, when the blocking portion 7233 seals the second end of the connection pipe 721, the connection pipe 721 is easily deformed, so that the blocking portion 7233 has a poor sealing effect on the second end of the connection pipe 721, and water leakage is easily caused. The second end of the connecting pipe 721 is communicated with one end of the fixing pipe 7253, and the fixing pipe 7253 is connected with the water receiving box 722 through the second connecting plate 7252, so that the second end of the fixing pipe 7253 is fixed, the blocking portion 7233 is opposite to the other end of the fixing pipe 7253, the connecting pipe 721 can be indirectly opened or blocked through opening or blocking the other end of the fixing pipe 7253, the blocking effect of the blocking portion 7233 on the second end of the connecting pipe 721 is enhanced, water leakage is prevented, and the functional reliability of the water level adjusting mechanism 720 is enhanced.

Illustratively, the blocking portion 7233 may be sleeved with a blocking end cap 7235, and the blocking end cap 7235 may be made of a flexible material such as rubber, so that when the blocking portion 7233 blocks the second end of the fixed tube 7253, the blocking end cap 7235 can deform to increase the contact area with the second end of the fixed tube 7253, thereby enhancing the blocking effect of the blocking portion 7233 on the second end of the fixed tube 7253.

In some implementations of embodiments of the present application, referring to fig. 24, the second connection plate 7252 is located above the rotation shaft 724, and the top end of the fixed tube 7253 may be in communication with the second end of the connection tube 721. The floating portion 7231 and the blocking portion 7233 may be located at the same side of the rotation shaft 724, and the blocking portion 7233 is located below the bottom end of the fixed pipe 7253. When the water level of the water receiving box 722 drops and the floating part 7231 drops down, the floating part 7231 can drive the blocking part 7233 to drop synchronously, so that the blocking part 7233 is far away from the bottom end of the fixed pipe 7253, and the second end of the connecting pipe 721 is opened to fill water into the water receiving box 722. When the water level in the water receiving box 722 rises, the floating part 7231 rises upwards, and the floating part 7231 can drive the blocking part 7233 to rise synchronously, so that the blocking part 7233 is close to the bottom end of the fixed pipe 7253, thereby blocking the second end of the connecting pipe 721 to stop water injection into the water receiving box 722. So set up, the connecting pipe 721 can downwardly extend for the water storage barrel 710 and the water in the connecting pipe 721 can fully get into the water receiving box 722, avoid the residual moisture in the connecting pipe 721 to breed bacteria, be favorable to guaranteeing the health of the pet.

In other implementations of embodiments of the present application, referring to fig. 25, the second connection plate 7252 is positioned below the rotation shaft 724, and the bottom end of the fixed tube 7253 may be in communication with the second end of the connection tube 721. The floating portion 7231 and the blocking portion 7233 may be located at different sides of the rotation shaft 724, and the blocking portion 7233 is located above the top end of the fixed pipe 7253. When the water level of the water receiving box 722 drops and the floating part 7231 drops down, the floating part 7231 can drive the blocking part 7233 to rise reversely, so that the blocking part 7233 is far away from the top end of the fixed pipe 7253, and the second end of the connecting pipe 721 is opened to fill water into the water receiving box 722. When the water level in the water receiving box 722 rises, the floating part 7231 rises upwards, and the floating part 7231 can drive the blocking part 7233 to reversely fall, so that the blocking part 7233 is close to the bottom end of the fixed pipe 7253, thereby blocking the second end of the connecting pipe 721 to stop water injection into the water receiving box 722. Thus, the connection pipe 721 is bent, so that the water in the water storage tank 710 is flowable when being injected into the water receiving box 722 through the connection pipe 721 and the fixing pipe 7253, and the water in the water feeding box 730 is flowable, thereby attracting pets to drink.

Illustratively, the adjustment member 723 may have a hollow structure, so that it is possible to reduce the weight of the adjustment member 723, reduce the buoyancy required for the floating portion 7231 to float upward, and thus ensure the functional reliability of the water level adjustment mechanism 720.

Referring to fig. 23 and 24, the surface of the floating portion 7231 facing the bottom of the water receiving box 722 is inclined. When the blocking portion 7233 blocks the second end of the connection pipe 721, the distance between the inclined surface and the bottom surface of the water receiving box 722 gradually increases in a direction away from the rotation shaft 724.

In the solution where the inclined surface is not provided, when the water level in the water receiving box 722 is lowered, the floating portion 7231 is lowered downward to contact the bottom surface of the water receiving box 722. As the water level in the water receiving box 722 further drops, the floating portion 7231 cannot further drop due to the blocking of the bottom surface of the water receiving box 722, so that the space around the end of the fixing tube 7253 for water discharge is too small, the flow rate of the water injected into the water receiving box 722 is reduced, and thus the efficiency of water injection into the water receiving box 722 and the water feeding box 730 is lowered. If the distance between the bottom surface and the floating surface of the water receiving box 722 is increased, the depth of the water receiving box 722 needs to be increased, so that the volume of the water level adjusting mechanism 720 is increased, which is not beneficial to miniaturizing the feeding device 600.

The inclined surface is provided on the side of the floating portion 7231 facing the bottom surface of the water receiving box 722, so that when the floating portion 7231 falls down, the floating range of the floating portion 7231 can be increased without increasing the depth of the water receiving box 722, and the floating portion 7231 can be prevented from prematurely contacting the bottom surface of the water receiving box 722 and failing to fall down. The lower the water level in the water receiving box 722, the larger the rotation range of the floating part 7231, so that the space around the end of the fixed pipe 7253 for water discharge is larger, thereby making the injection speed of water flow larger. That is, the water injection speed into the water receiving box 722 can be automatically adjusted according to the water level height in the water receiving box 722, thereby improving the water injection efficiency into the water receiving box 722 and the water feeding box 730.

Referring to fig. 17 and 18, the water feeding device 700 may further include a first connector 740, the first water outlet 712 of the water storage tub 710 is detachably connected to the water level adjustment mechanism 720 through the first connector 740, and the first connector 740 is configured such that the first water outlet 712 is communicated with the water level adjustment mechanism 720 when the water storage tub 710 is connected to the water level adjustment mechanism 720, and the first water outlet 712 is closed when the water storage tub 710 is separated from the water level adjustment mechanism 720. By the arrangement, the water storage barrel 710 can be detached from the water feeding device 700 for cleaning, the problem of water leakage of the water storage barrel 710 is avoided, and the cleaning convenience of the water feeding device 700 is improved.

Referring to fig. 19, 20 and 21, the first connector 740 may include a first connection member 741 connected to the water level adjustment mechanism 720, and a second connection member 742 connected to the water storage tub 710, the second connection member 742 being detachably connected to the first connection member 741, the second connection member 742 being configured to open the first water outlet 712 by the first connection member 741 when connected to the first connection member 741 and to close the first water outlet 712 when separated from the first connection member 741.

In the process of assembling the water feeding device 700, the first connection assembly 741 can be connected with the water storage tank 710, the second connection assembly 742 can be connected with the water level adjusting mechanism 720, for example, the second connection assembly 742 can be connected to the second end of the connection pipe 721, and then the first connection assembly 741 and the second connection assembly are connected, so that the convenience of the first connection assembly 741 and the second connection assembly 742 is improved. In addition, since the first connection member 741 and the second connection member 742 are separable from each other, the first connection member 741 or the second connection member 742 can be replaced or maintained independently without replacing the whole of the first connector 740 when the water feeding device 700 is maintained, thereby improving convenience in maintenance and reducing maintenance cost.

The end of the second sealing connection tube 754 facing away from the water receiving box 722 may be provided with a seventh connection portion 7511, and the seventh connection portion 7511 may abut against the sixth connection portion 7514. The second connector 750 may further include a second connection ring 7542, the second connection ring 7542 crimping the seventh connection portion 7541 onto the sixth connection portion 7514. That is, the second sealing connection cylinder 754 may be fixed to the sealing connection portion 751 of the second connection cylinder 751 by the second connection ring 7542.

In other implementations of embodiments of the present application, referring to fig. 28, the second seal connection cartridge 754 may also include an outer cartridge 7543, and an inner cartridge 7544 positioned within the outer cartridge 7543. The outer cylinder 7543 is connected with one end of the inner cylinder 7544 facing away from the water receiving box 722, a socket 7545 is formed at one end of the outer cylinder 7543 and the inner cylinder 7544 facing toward the water receiving box 722, the socket 7545 can be sleeved on the second connecting cylinder 751, the outer cylinder 7543 contacts with the outer side wall of the second connecting cylinder 751, and the inner cylinder 7544 contacts with the inner side wall of the second connecting cylinder 751. By doing so, the second sealing connection cylinder 754 can be sleeved on the second connection cylinder 751 without providing other parts to fix the second sealing connection cylinder 754, and the mechanical structure of the second connector 750 is simplified. In addition, the sixth connecting portion 751 is not required to be arranged on the second connecting cylinder 751, the seventh connecting portion 7511 is not required to be arranged on the second sealing connecting cylinder 754, and an additional second connecting ring 7542 is not required to be arranged, so that the volumes of the second connecting cylinder 751 and the second sealing connecting cylinder 754 are reduced, the installation space required by the second connector 750 is reduced, the distance between the second connecting cylinder 751 and the inner bottom surface of the water receiving box 722 is reduced, the residual water quantity in the water receiving box 722 is further reduced, bacteria are not easy to grow, and the body health of a pet is ensured.

Illustratively, the outer diameter of the sealing connection 751 of the second connection cylinder 751 may be greater than the outer diameter of the movable rod connection 751. The end of the outer cylinder 7543 facing the water receiving box 722 can be provided with a sixth limiting part 7546, the sixth limiting part 7546 extends towards the inner cylinder 7544, and is sleeved at the end of the sealing connecting part 7513 connected with the movable rod connecting part 7512. One end of the sealing connection portion 7513 connected with the movable rod connection portion 7512 can limit the sixth limit portion 7516, thereby limiting the second sealing connection cylinder 754, preventing the second sealing connection cylinder 754 from being separated from the second connection cylinder 751, and improving the structural reliability of the second connector 750.
