Detailed Description
In order to make the aforementioned features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.
Refer to fig. 1 to 6
The utility model provides an electronic induction garbage bin circuit board waterproof construction, is including the annular housing 1 of response garbage bin, the front end downside of annular housing is provided with an opening cavity 12 down, and circuit board 3 sets up in the cavity, the opening of cavity is filled in with the opening interference fit of cavity and is formed airtight space's sealing member 2, be provided with on the sealing member one be used for the winding displacement 31 on the circuit board to pass cross line hole 211, cross line hole and winding displacement interference fit.
In this embodiment, the top of the front end of the annular housing is further provided with an induction window, and a sealing plate is covered on the induction window.
In this embodiment, two sides of the region for mounting the circuit board at the front end of the annular housing are respectively provided with a rib 11, and the rib 11 and the inner side wall of the annular housing 1 form a cavity 12 with a lower opening so as to mount the circuit board 3.
In this embodiment, the sealing member is composed of a soft seal glue 21 and a hard plastic sheathing board 22, a peripheral ring of an outer side of an edge of the soft seal glue 21 is an inclined plane 213, an annular groove 212 is arranged on an inner side of the edge of the soft seal glue, and the hard plastic sheathing board 22 is sheathed in the annular groove 212 of the soft seal glue 21. In the design process, the fact that the whole material of the sealing element 2 is soft glue and the rigidity is not enough is considered, if the whole material of the sealing element 2 is hard glue, the sealing performance of the sealing element 2 and the inner wall of the cavity 12 is poor, and therefore the soft glue and the hard glue are combined, the whole rigidity of the sealing element is guaranteed, the edge of the sealing element is more attached to the inner wall of the cavity 12, and the waterproof performance is improved.
In this embodiment, the flexible sealing glue 21 is provided with a wire passing hole 211 for passing the flat cable 31 on the circuit board, and the cross section of the wire passing hole 211 on the flexible sealing glue 21 is the same as the cross section of the flat cable 31, so that the wire passing hole 21 on the flexible sealing glue is in interference fit with the flat cable 31.
In this embodiment, the hard plastic sheathing board 22 is correspondingly provided with a yielding hole 221 for yielding the line passing hole 211 on the soft sealing glue 21, so as to form the line passing hole of the sealing member 2 by matching with the line passing hole 211 on the soft sealing glue 21.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
