Problems solved by technology

[0003] In the prior art, the micro switch on the electric control box of the air conditioner is used to detect whether the middle frame is removed. Generally speaking, the middle frame directly presses down on the button of the micro switch vertically. Due to the manual installation of the middle frame, the force It will be very large, and it is easy to cause overvoltage to crush the button. Overvoltage will cause internal damage to the switch or poor contact, which will lead to program misjudgment and action failure.
On the other hand, the buttons of the micro switch are relatively small, and the depth tolerance between the micro switch and the middle frame is relatively large, so that the buttons cannot be pressed.

Embodiment 1

[0035] Example 1, such as Figure 1~3 As shown, the present invention discloses a switch device, comprising a switch box 3 and a guide post 4, the guide post 4 protrudes into the inside of the switch box 3, a switch main body 7 is arranged in the switch box 3, the One side of the switch body 7 is provided with a button 8, the other end of the button 8 is in contact with the shrapnel 9, the button 8 is set at an angle with the guide post 4, and the guide post 4 can slide and / or Or return to the original position, set the first groove 12 on the guide post 4, the contact 10 of the shrapnel 9 can extend into or slide out of the first groove 12 during the sliding process of the guide post 4, and the button 8 Can be squeezed by shrapnel 9.

[0036] The invention discloses a switch device. Through a button and a guide post arranged at an angle, when the guide post is not subjected to external force, the contact of the shrapnel is arranged in the first groove of the guide post. At th...

Embodiment 2

[0040] Example 2, such as Figure 1~2, 4 to 5, the present invention also discloses another switch device, the first groove 12 is set on the guide post 4 as a long-stroke groove, and the first boss is set on the long-stroke groove 11. The contact 10 of the elastic piece 9 can slide from the long-stroke groove on the lower part of the first boss 11 to the long-stroke groove on the upper part of the first boss 11 when the guide post 4 slides. The other structures are the same as in Embodiment 1. This structure further optimizes the structure of the guide post. When the guide post slides downward, when the contact of the shrapnel slides from the lower end of the long-stroke groove to the first boss, the shrapnel will press the button to proceed. For information transmission, when the contact of the shrapnel slides from the first boss to the upper end of the long-stroke groove, the button pops up, and the contact of the shrapnel does not contact the upper end of the long-stroke gr...

Embodiment 3

[0043] Embodiment 3, the present invention also discloses an air conditioner, comprising a base device 2 and a middle frame 1, the above-mentioned switch device is arranged on the base device 2, and the middle frame 1 is assembled with the base device 2 During the process, the guide post 4 can be squeezed to slide in the switch box 3 .

[0044] In the state where the middle frame 1 has not been installed, the contact 10 on the switch shrapnel 9 is in the first groove 12 of the guide post 4, and the 9 shrapnel is in a relaxed state without force. At this time, the contact 10 is in the shape of U-shaped structure.

[0045] When the middle frame is pressed up, the guide post 4 moves downward under the vertical downward pressure of the middle frame 1, and at the same time the spring 14 under the guide post 4 is compressed, and the guide post has a U-shaped shrapnel structure during the downward movement. It will leave the first groove on the plane of the guide post, and the U-sha...

Abstract

The invention provides a switching device and an air conditioner. The switching device comprises a switch box and a guide pillar, the guide pillar extends into the switch box; a switch main body is arranged in the switch box; a button is arranged on one side of the switch main body; the other end of the button is in contact with the elastic sheet; an included angle is formed between the button andthe guide pillar, the guide pillar can slide and / or return to the original position under the action of external force, a first groove is formed in the guide pillar, a contact of the elastic sheet can extend into or slide out of the first groove in the sliding process of the guide pillar, and the button can be extruded by the elastic sheet. The switching device provided by the invention is ingenious in structure, simple in connection and easy to produce and assemble, and the convenience and reliability of switch use are greatly improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a switch device and an air conditioner. Background technique [0002] In the existing air-conditioning equipment products, a micro switch is provided at the detection position such as the connection detection between the middle frame and the electric control box seat. When the detected condition reaches the preset condition, the contact part of the micro switch will be pressed to make The microswitch responds with a corresponding signal. [0003] In the prior art, the micro switch on the electric control box of the air conditioner is used to detect whether the middle frame is removed. Generally speaking, the middle frame directly presses down on the button of the micro switch vertically. Due to the manual installation of the middle frame, the force It will be very large, and it is easy to cause overvoltage to crush the button. Overvoltage will cause internal damage or p...
