Doorbell lens structure

Abstract

This application provides a doorbell lens structure, including a housing with symmetrical mounting holes on both sides, and a transparent outer lens cover on the front side of the housing; an inner ring mounted on the inner wall of the housing, with a motor mounted on the top side of the inner ring; and a cleaning plate mounted on the bottom surface of the rotating ring within a placement cavity. A gear meshes with the wall of the connecting toothed cavity, driving the gear to rotate and thus the rotating ring to rotate. The sliding cavity rotates under the constraint of a limiting rod mounted on the bottom wall of the inner ring, thereby driving the cleaning plate at the bottom of the rotating ring to rotate. The cleaning plate is elastic. When the cleaning plate rotates two revolutions to the position of the magnet, an external power supply increases the magnetism of the magnet. Under the action of magnetic attraction, the cleaning plate is bent and pressed against the side surface of the magnet, remaining within the placement cavity. When the power is disconnected, the cleaning plate returns to its original shape due to its own elasticity. The motor drives a cotton brush to clean the surfaces of the focusing area, the central viewing area, and the lower viewing area.

Description

Technical Field

[0001] This utility model relates to the field of doorbell lens technology, and more specifically, to doorbell lens structure. Background Technology

[0002] With the development of modern technology, smart home applications are becoming increasingly common, such as smart doorbells. While the Fresnel lens in smart doorbells has solved the problems of existing Fresnel lenses used in smart doorbells, the surface of the existing Fresnel lens is exposed, which inevitably leads to dust accumulation on the surface, affecting the upward and downward focusing effect of the surface, and manual cleaning is quite troublesome.

[0003] Therefore, we made improvements and proposed a doorbell lens structure. Utility Model Content

[0004] The purpose of this invention is to address the problem that when the surface of a Fresnel lens is exposed to the outside, dust inevitably settles on the surface, affecting the light-gathering effect of the upper and lower parts of the lens.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] A doorbell lens structure was developed to improve the aforementioned problems.

[0007] The application is as follows:

[0008] The device includes a housing with symmetrical mounting holes on both sides, and a transparent outer lens cover on the front side of the housing; a lens body mounted on the inner bottom wall of the housing, the lens body having a focusing area, a middle viewing area, and a lower viewing area arranged sequentially from top to bottom; a magnet mounted on the top side of the inner wall of the housing; an inner ring mounted on the inner wall of the housing, the top side of the inner ring having a motor mounted on it, and a limiting rod mounted on the inner bottom wall of the inner ring; and a rotating ring, with a placement cavity between the rotating ring and the inner bottom wall of the housing, the bottom surface of the rotating ring being located within the placement cavity and having a cleaning soft plate installed thereon.

[0009] Because the gear meshes with the wall of the connecting tooth cavity, it drives the gear to rotate, which in turn drives the rotating ring to rotate. The sliding cavity rotates in a circle under the constraint of the limiting rod installed on the bottom wall of the inner ring, which in turn drives the cleaning plate at the bottom of the rotating ring to rotate. The cleaning plate is placed in the cavity between the rotating ring and the inner wall of the outer shell. The cleaning plate is elastic. When the cleaning plate rotates two revolutions to the position of the magnet, the external power supply increases the magnetism of the magnet, causing it to attract the cleaning plate and bend it so that it sticks to the side surface of the magnet. At this time, the cleaning plate is also in the cavity, achieving the function of storage. When the power is disconnected, the cleaning plate returns to its original shape under its own elasticity. The starter drives the cotton brush to clean the surface of the focusing area, the middle viewing area, and the lower viewing area.

[0010] As a preferred embodiment of the doorbell lens structure provided by this utility model, the rotating ring includes a sliding cavity and a connecting tooth cavity, and one side of the inner wall of the connecting tooth cavity is provided with a tooth groove.

[0011] In a preferred embodiment of the doorbell lens structure provided by this utility model, a limiting cavity is provided between the inner ring and the top side of the outer shell, and one end of the limiting rod extends to the sliding cavity inside the rotating ring.

[0012] In a preferred embodiment of the doorbell lens structure provided by this utility model, the output end of the motor extends into the interior of the connecting tooth cavity and a gear is installed thereon, the gear being meshed with the tooth grooves on the inner wall of the connecting tooth cavity.

[0013] In a preferred embodiment of the doorbell lens structure provided by this utility model, a cotton brush is provided at the bottom of the cleaning plate. The cotton brush is a metal sheet with a certain elasticity, and the magnet is externally powered to enhance its magnetism.

[0014] In a preferred embodiment of the doorbell lens structure provided by this utility model, the thickness of the magnet gradually increases from the left end to the right end.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] Because the gear meshes with the wall of the connecting tooth cavity, it drives the gear to rotate, which in turn drives the rotating ring to rotate. The sliding cavity rotates in a circle under the control of the limiting rod installed on the bottom wall of the inner ring, which in turn drives the cleaning soft plate at the bottom of the rotating ring to rotate. The cleaning soft plate is placed in the cavity between the rotating ring and the inner wall of the outer shell. The cleaning soft plate is elastic. When the cleaning soft plate rotates two revolutions to the position of the magnet, the external power supply increases the magnetism of the magnet, causing the cleaning soft plate to bend and stick to the side surface of the magnet under the action of magnetic attraction. At this time, the cleaning soft plate is also in the cavity, achieving the function of storage. When the power is disconnected, the cleaning soft plate returns to its original shape under its own elasticity. The starter drives the cotton brush to clean the surface of the focusing area, the middle viewing area, and the lower viewing area. Attached Figure Description

[0034] Example 1

[0035] Please refer to Figure 1-6 The doorbell lens structure includes a housing 1 with symmetrical mounting holes 11 on both sides, and a transparent outer lens cover 3 on the front side of the housing 1; a lens body 2 mounted on the inner bottom wall of the housing 1, which has a focusing area 21, a middle viewing area 22, and a lower viewing area 23 arranged sequentially from top to bottom; a magnet 6 mounted on the top side of the inner wall of the housing 1; an inner ring 5 mounted on the inner wall of the housing 1, with a motor 51 mounted on the top side of the inner ring 5 and a limiting rod 54 mounted on the inner bottom wall of the inner ring 5; and a rotating ring 7, with a placement cavity 12 between the rotating ring 7 and the inner bottom wall of the housing 1, and a cleaning soft plate 4 mounted on the bottom surface of the rotating ring 7 within the placement cavity 12. The rotating ring 7 includes a sliding cavity 71 and a connecting tooth cavity 72, with a toothed groove on one side of the inner wall of the connecting tooth cavity 72. A limiting cavity 52 is provided between the inner ring 5 and the top side of the housing 1, and one end of the limiting rod 54 extends into the sliding cavity 71 inside the rotating ring 7. The output end of motor 51 extends into the interior of connecting tooth cavity 72 where gear 53 is installed. Gear 53 meshes with the tooth grooves on the inner wall of connecting tooth cavity 72. A cotton brush 41 is provided at the bottom of cleaning soft plate 4. The cotton brush 41 is a metal soft sheet with a certain degree of elasticity. Magnet 6 is externally powered to enhance magnetism.

[0036] Mounting hole 11 is used for doorbell installation. Since motor 51 is installed on the top side of inner ring 5, and gear 53 meshes with the wall of connecting tooth cavity 72, motor 51 drives gear 53 to rotate, thereby driving rotating ring 7 to rotate. Sliding cavity 71 rotates in a circle under the restriction of limiting rod 54 installed on the bottom wall of inner ring 5, thereby driving cleaning soft plate 4 at the bottom of rotating ring 7 to rotate. The bottom of cleaning soft plate 4 is cotton brush 41, which contacts focusing area 21, middle viewing area 22, and lower viewing area 23. Cleaning soft plate 4 is placed in placement cavity 12 between rotating ring 7 and inner wall of outer shell 1. Cleaning soft plate 4 rotates two revolutions to magnet 6. After positioning, the cleaning plate 4 is elastic. The magnet 6 has different thicknesses, so the attraction force is also different. The external power supply increases the magnetism of the magnet 6, causing it to attract the cleaning plate 4 and bend it so that it sticks to the side surface of the magnet 6. At this time, the cleaning plate 4 is also in the placement cavity 12, achieving the function of storage, without obstructing the viewing of the outside through the focusing area 21, the middle viewing area 22, and the lower viewing area 23. When the power is disconnected, the cleaning plate 4 returns to its original shape under its own elasticity. As the motor 51 starts, it drives the cotton brush 41 to clean the surface of the focusing area 21, the middle viewing area 22, and the lower viewing area 23. The outer lens cover 3 can be snapped open with the outer shell 1.

[0037] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
