Description

Technical Field

[0001] The utility model relates to the technical field of pet equipment, and particularly relates to an intelligent cat litter box including a weighing induction device. Background Art

[0002] The cat litter box of the present utility model generally refers to a device for collecting excreta of pets such as cats and dogs. The workload of cat litter cleaning operation is large, and the user experience of manual cat litter cleaning is not good. Some cat litter boxes with automatic cat litter cleaning have emerged on the market, which reduces the workload of manual cleaning. The intelligent cat litter box with automatic cat litter cleaning needs to be able to monitor and identify the actions of pets entering and using the toilet, so as to determine the start and stop of the cleaning program. There are many monitoring methods, and the monitoring method based on a weighing sensor is a widely used method, such as the solution disclosed in Chinese Patent No. 201910997843.6.

[0003] However, in the prior art, the typical fixing method of the weighing sensor is as Figure 1 shown. A clamping tooth is provided on the weighing sensor assembly. First, the clamping tooth is passed through the upper surface of the base from bottom to top to initially fix the weighing sensor, and then the weighing sensor assembly is fixed to the base with screws from top to bottom. In this design, there is inevitably a gap A between the clamping tooth and the upper surface of the base, resulting in that cat litter particles, dust, etc. are easily fallen into the weighing sensor assembly from the gap A, and the fallen dust and impurities cannot be removed by themselves. The accumulation will affect the sensitivity of the weighing sensor, and the structure of the existing design is also too complex. Summary of the Utility Model

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide an intelligent cat litter box, including: a main body, a base; a weighing induction device is arranged below the base; the weighing induction device includes a deformation area bracket, an outer bracket and a weighing induction module; the deformation area bracket includes upper and lower parts, and the upper diameter of the deformation area bracket is larger than the lower diameter of the deformation area bracket; a plurality of screw holes and clamping teeth are arranged on the outer bracket; a through hole is arranged in the middle of the outer bracket, and the diameter of the through hole is larger than the lower diameter of the deformation area bracket but smaller than the upper diameter of the deformation area bracket; the weighing induction module includes a deformation area.

[0005] Preferably, in the above-mentioned intelligent cat litter box, the outer bracket further includes a positioning block.

[0006] The present utility model further provides a weighing induction device, comprising: a deformation area support, an outer support and a weighing induction module; the deformation area support comprises an upper part and a lower part, and the diameter of the upper part of the deformation area support is larger than that of the lower part of the deformation area support; a plurality of screw holes and teeth are arranged on the outer support; a through hole is arranged in the middle of the outer support, and the diameter of the through hole is larger than that of the lower part of the deformation area support but smaller than that of the upper part of the deformation area support; the weighing induction module comprises a deformation area.

[0008] The intelligent cat litter box of the present utility model adopts a newly designed weighing induction device, which is not only simple to install, but also avoids the adverse effects of dust accumulation on the induction device, thus having a high practical value.

[0012] The following specific examples illustrate the embodiments of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model.

[0013] Please refer to the accompanying drawings below. It should be noted that the diagrams provided in this embodiment only illustrate the basic concept of the present utility model in a schematic manner. Therefore, only the components related to the present utility model are shown in the diagrams, rather than being drawn according to the number, shape and size of the components in actual implementation. The type, quantity and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex. Unless otherwise specified, the words indicating directions such as "upper", "lower", "left", "right", etc. used in the text are based on the perspective of the observer of the drawings.

[0014] Figure 1 is a schematic diagram of an embodiment of the present utility model. The intelligent cat litter box of the present utility model comprises a main body 1 and a base 2. At least one weighing induction device 3 is arranged below the base 2.

[0015] Refer to the following Figure 2 . As shown in the figure, the weighing induction device 3 of the present utility model includes a deformation area bracket 31, an outer bracket 32, and a weighing induction module 33.

[0016] The deformation area bracket 31 includes upper and lower parts, and the upper part has a larger diameter than the lower part. The outer bracket 32 is provided with screw holes 321 and teeth 322, and a through hole 323 is provided in the middle of the outer bracket 32. The diameter of the through hole 323 is slightly larger than the lower part of the deformation area bracket 31 but smaller than the upper part of the deformation area bracket 31. For the convenience of quick installation of the outer bracket, preferably, a positioning block 324 can be provided outside the outer bracket, so as to facilitate positioning when the weighing induction device is fixed to the base. The weighing induction module 33 includes a deformation area 331.

[0017] During assembly, the deformation area 331 of the weighing induction module abuts downward against the upper end of the deformation area bracket 31, then the lower part of the deformation area bracket 31 is passed through the through hole 323, and the weighing induction module 33 and the deformation area bracket 32 are pressed down together until the teeth 322 catch the upper part of the weighing induction module 33. Figure 3 The figure shows a schematic diagram of the assembled weighing induction device 3. Finally, the weighing induction device 3 is fixed to the base 2 from bottom to top using fixing screws.

[0018] The advantages of using the above design are as follows: There is no need to open holes on the upper surface of the base, and all the gaps of the weighing induction device face downward. Moreover, during use, there are continuous small relative position changes between the deformation area bracket 31 and the outer bracket 32. Even if a small amount of impurities enter the gaps between the components of the weighing induction device, they will be shaken off during use, thus greatly reducing the influence of dust and impurities on the weighing induction device.

[0019] The above embodiments only illustrate the principle and its effects of the present utility model by way of example, and are not used to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
