In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0037] The present embodiment provides a pet litter box, referring to Figures 1 to 6 As shown in the figure, the pet litter box comprises a base 100, a litter box body 200 and a sand storage cylinder 300, wherein the litter box body 200 is rotatably arranged on the base 100, the litter box body 200 has an access 201, and a toilet room 202 communicating with the access 201 is arranged in the litter box body 200. The sand storage cylinder 300 is fixedly arranged in the toilet room 202 and can rotate together with the litter box body 200 on the base 100, the sand storage cylinder 300 is coaxially arranged with the rotation shaft of the litter box body 200, the sand storage cylinder 300 is provided with a sand storage cavity 301 for storing pet litter, and the side wall of the sand storage cylinder 300 in the radial direction is provided with a sand adding pipe 310 communicating with the sand storage cavity 301, the sand outlet port 311 of the sand adding pipe 310 is lower than the access 201, and the pet litter in the sand storage cylinder 300 can be added to the toilet room 202 through the sand adding pipe 310 under the action of gravity.

[0038] In the present embodiment, when the height level of the pet litter inside the toilet chamber 202 of the litter basin main body 200 is lower than the height of the sand outlet port 311 of the sand adding pipe 310, the pet litter inside the sand storage cylinder 300 will automatically drop and be added into the toilet chamber 202 through the sand adding pipe 310 due to gravity. When the height of the pet litter inside the toilet chamber 202 gradually rises and is level with the height of the sand outlet port 311, the pet litter inside the toilet chamber 202 will block the sand outlet port 311, so that the pet litter inside the sand storage cylinder 300 will not continue to drop, i.e. the sand storage cylinder 300 will automatically stop adding sand. The above process can realize automatic addition of pet litter, and the pet litter addition process can be realized only by gravity, without the need for additional communication and driving devices such as automatic control devices and sensing modules, so that the structure is simple, the overall structure of the pet litter basin is effectively simplified, and the production and use costs are reduced.

[0039] When the litter basin main body 200 is in a horizontal position, the sand adding pipe 310 is in a vertical position relative to the base 100 under the action of gravity. Figure 4 In the present embodiment, the angle of the litter basin main body 200 is adjusted, the litter basin main body 200 is rotated relative to the base 100, and the sand storage cylinder 300 fixed inside the toilet chamber 202 rotates together with the litter basin main body 200. When the rotation angle of the sand storage cylinder 300 relative to the base 100 is small, the sand adding pipe 310 is slightly rotated upward, and in this process, the communication part of the sand storage cavity 301 and the sand adding pipe 310 is still lower than or partially lower than the height of the pet litter inside the sand storage cavity 301, i.e. the height of the pet litter inside the sand storage cavity 301 can still cover or partially cover the sand adding pipe 310. At this time, if the sand outlet port 311 of the sand adding pipe 310 is higher than the pet litter inside the toilet chamber 202, the pet litter inside the sand storage cavity 301 will still drop and be added into the toilet chamber 202 due to gravity. Then, the litter basin main body 200 continues to rotate, and in this process, the rotation angle of the sand storage cylinder 300 relative to the base 100 becomes larger and larger, and the sand adding pipe 310 continues to rotate upward. In this process, the communication part of the sand storage cavity 301 and the sand adding pipe 310 starts to gradually come out of the pet litter, until the height of the pet litter inside the sand storage cavity 301 is completely lower than the sand adding pipe 310, at which time the pet litter inside the sand storage cavity 301 will automatically stop the adding work.

[0040] It can be understood that, under the condition that the amount of pet litter inside the sand storage cylinder 300 is sufficient, in the rotation process of the litter basin main body 200 relative to the base 100, the pet litter inside the sand storage cavity 301 will still drop and be added into the toilet chamber 202 due to gravity within a certain angle range. In this case, the height of the pet litter inside the toilet chamber 202 is higher than the height of the sand outlet port 311 of the sand adding pipe 310 in the vertical state. It is acceptable that the height of the pet litter inside the toilet chamber 202 is slightly higher than the target height by a certain distance, but if the height of the pet litter 202 is too high, there will be a risk of spilling out of the entrance 201 and outward.

[0041] To solve the above problems, with reference to Figures 2 to 6 As shown in FIG. 3, the sand storage cylinder 300 is provided with a throttling baffle 320 at the end away from the sand adding pipe 310, and the lower end of the throttling baffle 320 and the inner wall of the sand storage cavity 301 jointly form a throttling sand outlet 321. The throttling baffle 320 can jointly form the throttling sand outlet 321 with the inner wall of the sand storage cavity 301, and the throttling sand outlet 321 can limit the flow of pet sand discharged downward in the sand storage cavity 301. Specifically, after the throttling baffle 320 is provided, part of the pet sand in the sand storage cavity 301 is blocked by the throttling baffle 320, so that the pet sand can only reach the sand adding pipe 310 through the throttling sand outlet 321. At the same rotation angle, the discharge amount of pet sand can be effectively reduced, and the automatic addition of pet sand can be stopped earlier during the rotation of the sand basin main body 200, so that the height of pet sand in the toilet room 202 is not too high, and the height of pet sand does not exceed the entrance and exit 201 and leak out of the pet sand basin.

[0042] In this embodiment, when the sand basin main body 200 is preferably rotated by 35° relative to the base 100, the sand storage cylinder 300 stops automatically adding pet sand.

[0043] Further optionally, the end of the throttling baffle 320 away from the throttling sand outlet 321 is rotatably arranged on the inner wall of the sand storage cavity 301, so that the flow area of the throttling sand outlet 321 can be selectively adjusted. As an optional embodiment, with reference to Figure 7 As shown in FIG. 3, a rotating hole is formed at the end of the throttling baffle 320 away from the throttling sand outlet 321, and a rotating shaft 3011 is rotatably arranged on the inner wall of the sand storage cavity 301, and the throttling baffle 320 is fixedly sleeved on the rotating shaft 3011 through the rotating hole. Specifically, the end of the throttling baffle 320 away from the throttling sand outlet 321 extends out of the sand storage cavity 301, and the angle of the throttling baffle 320 is adaptively adjusted by pulling the extended end of the throttling baffle 320.

[0044] Continuing to refer to Figure 2 As shown in FIG. 3, the sand basin main body 200 includes a fixed plate 210, the sand basin main body 200 is provided with a mounting hole 203, the fixed plate 210 is fixedly sleeved on the mounting hole 203, the sand storage cylinder 300 is provided with a plug-in head 302, and the fixed plate 210 is correspondingly provided with a plug-in slot (not shown). The plug-in head 302 penetrates the mounting hole 203 and is plugged into the plug-in slot. In this embodiment, the sand storage cylinder 300 is detachably arranged with the sand basin main body 200, and when the sand storage cylinder 300 needs to be detached, the plug-in head of the sand storage cylinder 300 is pulled out of the plug-in slot on the fixed plate 210.

[0045] Further, the upper part of the sand storage cylinder 300 is movably provided with a cylinder cover 350, which can open and close the sand storage cavity 301. When it is necessary to supplement the pet sand in the sand storage cylinder 300, the cylinder cover 350 can be opened, and the pet sand can be timely supplemented into the sand storage cavity 301. Further, the sand storage cylinder 300 is sleeved with a fixed shell 340, which can protect the sand storage cylinder 300, and the plug connector 302 is provided on the fixed shell 340.

[0046] Further specifically, referring to FIG. 2, the fixed plate 210 is provided with a clamping head (not shown), and the outer edge of the mounting hole 203 is correspondingly provided with a clamping portion 2031. The clamping head is adapted to be clamped with the clamping portion 2031 when the fixed plate 210 is sleeved on the mounting hole 203. The structure is simple, and the operation is convenient. Figures 2 to 3

[0047] Further optionally, referring to FIG. 3, the pet sand basin further comprises a gravity sensor 331 and an alarm module 332, which are in communication connection. The gravity sensor 331 can detect the weight of the pet sand in the sand storage cavity 301, so as to monitor the amount of the pet sand in the sand storage cavity 301 in real time. Specifically, the gravity sensor 331 is in communication connection with the alarm module 332 through a control module (not shown). When the alarm module 332 detects that the weight of the pet sand in the sand storage cavity 301 is lower than a threshold value, the alarm module 332 sends a signal to the control module, so that the control module controls the alarm module 332 to alarm in time, thereby timely reminding the pet owner to supplement the pet sand in the sand storage cavity 301. Figure 8

[0048] In the embodiment, the control module can be selected as a PCB board, and the alarm module 332 is provided as an alarm lamp 3321 and / or a buzzer 3322. The communication control process between the control module and the gravity sensor 331 and the alarm module 332 is the prior art, and will not be described in detail here.

[0049] The pet sand basin provided in the embodiment can be applied to different pets such as cats, dogs, and mice. Other structures of the pet sand basin not mentioned in the specification are the prior art, and will not be described in detail here.
