Furthermore, if the terms "first" and "second" are used for descriptive purposes only, they are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features. Thus, a definition of "a first" or "a second" feature may explicitly or implicitly include one or more of the features, and in the description of the invention, "a number" or "a number" means two or more unless explicitly specified otherwise.
The first embodiment is as follows:
as shown in fig. 1, an anti-interference flat-layer photoelectric switch comprises a body 1, wherein the body 1 is arranged on an elevator, the body 1 is provided with a shell, a sealing connecting block, a light-transmitting plate 12, a rear cover and a U-shaped groove 11, the anti-interference flat-layer photoelectric switch also comprises a wiper 2, the wiper 2 is arranged in the elevator shaft, the wiper 2 is divided into a head part a, a body part b and a tail part c from top to bottom, the width of the head part and the width of the tail part are smaller than that of the U-shaped groove 11, the width of the body part is larger than that of the U-shaped groove 11, the wiper 2 comprises a framework 21 and an elastic cladding piece, and a wiping cloth 23.
The basic structure of the body 1 is the same as that of the prior art, such as that disclosed in patent No. 2018202243478, and the applicant does not need to describe any further details here.
The preferred wiper 2 in this embodiment is mounted in the top position of the whole elevator hoistway, i.e. when the elevator reaches the topmost end of the hoistway, the body 1 and the wiper 2 can be in contact to facilitate the simultaneous inspection of the wiper 2 and the wiping cloths 23 of its surface during the elevator service.
The wiping cloth 23 of the present embodiment is adhered to the covering member by a double-sided tape, and the double-sided tape between the wiping cloth 23 and the covering member is located at the head and the tail.
The wiping cloth 23 in the present embodiment is preferably an ultra-fine fiber cloth.
The bonding part of the wiping cloth 23 and the wrapping member at least comprises a head part and a tail part, when the body 1 and the wiper 2 move relatively, the body 1 and the wiping cloth 23 on the surface of the wiper 2 generate friction, and the wiping cloth 23 is fixed on the head part and the tail part, so that the body 1 can be prevented from displacing the wiping cloth 23.
The wiping cloth 23 is fixed through the double-sided adhesive tape, and the wiping cloth 23 can be conveniently replaced after being worn.
