Problems solved by technology

[0002] Most of the existing switches used to control electric lights, ceiling fans and other electrical appliances are push switches, toggle switches or knob switches installed on the wall. In the impression of ordinary users, they are charged and dangerous, and they are rarely cleaned. They are easy to breed bacteria after long-term use, and there is an unhygienic situation.
Especially for switches installed in public places (such as hospitals), direct contact with hands has the risk of bacterial virus infection

Embodiment 1

[0041] combine Figure 1 to Figure 3 As shown, this embodiment is a non-contact inductive switch. It includes a housing 91 and a panel 92 fixedly connected to the front end of the housing; the upper part of the panel is formed with three induction air outlets 922 along the horizontal direction, Every An air outlet pipe 97 is slidably installed in each induction air outlet, and a centrifugal fan 95 is installed in the housing, and the air outlet port of the centrifugal fan is connected to one end of each air outlet pipe positioned at the inside of the panel through a hose. The centrifugal fan is provided with three air outlet ports 951 .

[0042] An air inlet 921 communicating with the air inlet end of the centrifugal fan is formed on the lower part of the panel.

[0043] A sensor mount 923 is formed above the position corresponding to each induction air outlet on the inner wall of the panel, and there is a gap between each sensor mount and the air outlet pipe at the correspo...

Embodiment 2

[0065] The difference between this embodiment and Embodiment 1 is that the control switch includes a rotary adjustment switch and a stepping motor coaxially connected with the knob of the rotary adjustment switch.

[0066] When adjusting a certain rotary adjustment switch, use finger a to block the corresponding induction air outlet, so that the pressure value of the pressure sensor at the corresponding position is greater than the set pressure a, and then use another finger b to block the other two within the set time b. One of the four induction air outlets is used to control the forward and reverse rotation of the stepper motor.

[0067] The induction air outlet blocked by finger a is defined as the target air outlet, and the induction air outlet blocked by finger b is defined as the adjusted air outlet.

[0068] 1) When the adjustable air outlet blocked by finger b is on the left side relative to the other adjusted air outlet, the control circuit board controls the stepper...

Abstract

The invention discloses a non-contact inductive switch. The non-contact inductive switch comprises a shell and a panel fixedly connected to a front end of the shell; three induction air outlets are formed on an upper part of the panel along the horizontal direction, an air outlet pipe is slidably installed in each induction air outlet, a centrifugal fan is installed in the shell, and the centrifugal fan is connected with one end of each air outlet pipe located on an inner side of the panel through a hose; sensor mounting seats are formed above positions corresponding to the induction air outlets on an inner wall of the panel, and each sensor mounting seat and the air outlet pipe at the corresponding position are connected by a pressure sensor; a pyroelectric sensor is installed below the induction air outlets on the panel; three control switches for controlling the on-off of the circuit are arranged on a control circuit board, and three pressure sensors respectively control one controlswitch; and according to the non-contact inductive switch disclosed by the invention, the operations of opening, closing and adjustment are achieved by acing the reaction force of the airflow on thepressure sensors, the function of a non-contact switch is achieved, and the non-contact inductive switch is safe and sanitary.

Description

technical field [0001] The invention belongs to the technical field of switches, and in particular relates to a non-contact induction switch. Background technique [0002] Most of the existing switches used to control electric lights, ceiling fans and other electrical appliances are push switches, toggle switches or knob switches installed on the wall. In the impression of ordinary users, they are charged and dangerous, and they are rarely cleaned. They are easy to breed bacteria after long-term use, and there is an unhygienic situation. Especially for switches installed in public places (such as hospitals), direct contact with hands poses a risk of bacterial virus infection. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a safe and hygienic non-contact inductive switch that is easy to use, can integrate multiple switches on one panel, and avoids misoperation. [0004] In order to realize the object of the pre...
