Technical Field

[0001] The utility model relates to the technical field of pet feeding devices, in particular to an anti-pinch feeder. Background Art

[0002] Feeders are used for feeding pets. In the demand for home feeding, the automation level of feeders is increasingly required. There is a type of feeder that generally includes a food bowl, a cover that can close the food bowl, and an induction tag. The cover is driven by an electric motor and a driving structure. The induction tag is worn on the pet. When the pet approaches, the electric motor starts to open the cover so that the pet can eat food conveniently. When the pet leaves, the electric motor starts to close the cover. Therefore, the prior art mainly considers the anti-pinch design in the induction tag and the corresponding electric control design, but this is an ideal state. Although the prior art can achieve a certain anti-pinch function, how to further reduce the risk of pinching the pet requires further research.

DETAILED DESCRIPTION

[0025] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are for example only, and those skilled in the art may think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0026] like Figures 1 to 7 The figure shows an anti-pinch feeder, comprising a food bowl 1 and a cover 2 that can close the food bowl 1, the cover 2 is driven by an electric motor 3, and also comprises a cylindrical barrel 6, the cover 2 is arranged around the cylindrical barrel 6 and the two are transmission connected, the output shaft 9 of the electric motor 3 extends to the inner side of the cylindrical barrel 6 and is connected to the driving part 10, the driving part 10 is transmission connected to the cylindrical barrel 6, and the transmission connection is arranged as a slippable structure, when the cover 2 is blocked from closing, the driving part 10 and the cylindrical barrel 6 slip relatively.

[0027] The electric motor 3 is provided with a reduction box 13 on one side of the output shaft 9. The power of the electric motor 3 is decelerated by the reduction box 13 and then outputted from the output shaft 9. The reduction box 13 is, for example, a gear reduction box 13, preferably a planetary gear reduction box 13. For simplicity of illustration, Figure 6 The planetary gears and other structures of the reduction box 13 are not drawn, but this does not hinder the understanding of the technical solution.

[0028] In some embodiments, Figure 1 , 2As shown, the columnar barrel 6 includes a first end 7 and a second end 8, the first end 7 is provided with a first gear 11, the second end 8 is provided with a second gear 12, one side edge of the cover plate 2 is provided with a first rack, the other side edge of the cover plate 2 is provided with a second rack, the first gear 11 is meshed and connected with the first rack, and the second gear 12 is meshed and connected with the second rack. In this way, the transmission is stable and reliable.

[0029] In some embodiments, Figure 6 As shown, the electric motor 3 is located in the cylindrical barrel 6 and is rotatably sleeved with the cylindrical barrel 6. This makes the structure more compact.

[0030] Further, such as Figure 4 , 5 , 6, and 7, it also includes a first bracket 4 and a second bracket 5, a columnar barrel 6 is rotatably connected between the first bracket 4 and the second bracket 5, the outer ring of the driving part 10 is drivingly connected to the inner ring of the columnar barrel 6 to form a first support for the electric motor 3, and the electric motor 3 extends to the second bracket 5 and is connected to the second bracket 5 to form a second support for the electric motor 3. In this way, the electric motor 3 is suspended, which is conducive to reducing vibration and noise.

[0031] like Figure 1 , 2 As shown in FIG. 6 , the columnar barrel 6 includes a first end and a second end, the first bracket 4 is rotatably connected to the first end via a bearing, and the second bracket 5 is rotatably connected to the second end via a bearing, such as a bushing.

[0032] Further, such as Figure 4 , 5 , 6, and 7, it also includes a cover 17, the electric motor 3 is sleeved with the cover 17, the electric motor 3 extends toward the second bracket 5 and is connected to the second bracket 5 to form a second support for the electric motor 3, that is, the cover 17 extends toward the second bracket 5 and is connected to the second bracket 5 to form a second support for the electric motor 3, and the cover 17 extends toward the second bracket 5 to form an extension end 14. In this way, on the one hand, it is convenient for production and assembly, and on the other hand, a conventional electric motor 3 can be used without customization.

[0033] In some embodiments, Figure 3 , 4As shown in Figure 6, the slip structure includes a radially retractable first tooth 15 arranged in the circumference of the driving part 10, and a second tooth 16 matched with the first tooth 15 is arranged on the inner ring of the columnar barrel 6. When the cover plate 2 is blocked from closing, the first tooth 15 can be pushed by the second tooth 16 to radially retract and jump out of the match with the second tooth 16, thereby forming relative slippage. In this structure, the first tooth 15 is provided with a chamfer or an arc surface along the circumference, and the corresponding second tooth 16 is also provided with a chamfer or an arc surface. Then, when the cover plate 2 is blocked, the first tooth 15 can be pushed by the second tooth 16 to radially retract and jump out of the match with the second tooth 16 through the chamfer or the arc surface, thereby forming relative slippage. In this way, on the one hand, when the cover plate 2 is not blocked, it has better transmission performance, and on the other hand, when the cover plate 2 is blocked, it can slip immediately. At the same time, during the continuous slipping process, since the first tooth 15 has been pushed back, the force applied by the first tooth 15 to the second tooth 16 is very small during the continuous slipping process, so the damage to the pet can be reduced and the pet can be more easily escaped from the clamped state.

[0034] Further, such as Figure 3 As shown, the second teeth 16 are provided in plurality, forming a circumferential gear ring in the inner circle of the cylindrical barrel 6. In this way, on the one hand, when the clamping state is released, the first teeth 15 and the second teeth 16 can immediately resume the matching, and on the other hand, in the clamping state, each second tooth 16 of the gear ring can keep the first teeth 15 in the retracted state, so as to facilitate the realization that during one rotation, the force applied by the first teeth 15 to the second teeth 16 is kept very small.

[0035] Further, such as Figure 4 , 6 As shown, one or two first teeth 15 are provided, and when two first teeth 15 are provided, the two first teeth 15 are evenly provided along the circumferential direction. In this way, when two first teeth 15 are provided, the arrangement is more balanced.

[0036] In some embodiments, Figure 4 , 6 As shown, the driving part 10 is provided with radial holes in the circumference, and an elastic member 18 is provided in the radial hole. The first tooth 15 is installed in the radial hole and is abutted against the elastic member 18. The elastic member 18 provides elastic force for radial expansion and contraction of the first tooth 15. In this way, the structure is simple and the assembly is convenient. Moreover, the elastic force can be optimized by testing different elastic members 18, so as to select a better solution.

[0037] Of course, the slippable structure may also be other mechanisms, for example, the slippable structure may adopt a friction transmission structure. In the present disclosure, any applicable slippable structure may be adopted, and is not limited to the slippable structure exemplified in the embodiment.

[0038] When understanding the present disclosure, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration here.

[0039] The above description is only an illustrative embodiment of the present invention, so any equivalent changes or modifications made according to the structure, characteristics and principles described in the patent protection scope of the present invention are included in the patent protection scope of the present invention.
