Description

A new type of normally open and normally closed thermostat structure

Technical field

The invention relates to the technical field of thermostats, and in particular to a new type of normally open and normally closed thermostat structure.

Background technique

Currently in the home appliance industry, thermostats are widely used in refrigerators, washing machines, soymilk machines, and smart toilets for over-temperature protection. Conventional thermostat products are basically unipolar or bipolar structures. These commonly used structures are It is a normally closed structure. Normally closed structure: when the temperature rises, the contacts are disconnected. When the temperature drops, the contacts are connected. Normally open structure: when the temperature rises, the contacts are connected. When the temperature drops, the contacts are disconnected. At present, single-pole thermostats cannot be compatible with normally closed and normally open after being disconnected. The normally open and normally closed combinations on the market only have bipolar structures, but this structure is divided into two groups of temperatures. One group is Normally closed type, the other group is normally open type. When working, the temperature rises, the normally closed type is disconnected, and the other group of normally open type is connected, and the normally open type is connected. The action difference between the two is large, and it is not the same. It can ensure simultaneous action, and the structure is large, so it is not suitable for the installation of small electrical appliances.

Detailed ways

The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

According to Figure 1-Figure 7

The housing 1 includes a support ring 11, a movable central hole 12 and a terminal slot 13 arranged from top to bottom;

The contact mechanism 2 is located in the movable central hole 12 and includes a static contact component 21, a moving contact component 22 and a terminal component 23. The static contact component 21 is located on the top of the movable contact component 22, and the wiring The terminal component 23 is provided at the front end of the movable contact component 22;

The top cover mechanism 3 is located on the top of the housing 1 and includes a thermal conductive cover 31, a bimetal sheet 32 and a guide frame 33 arranged from top to bottom.

Because the static contact component 21 includes a static contact piece 210, a static contact point 211, a static contact rivet 212 and a static contact end piece 213, and the static contact piece 210 is fixed inside the movable middle hole 12 through the static contact rivet 212, The static contact end piece 213 is provided at the bottom of the static contact rivet 212, and the static contact point 211 is provided at the bottom of the static contact piece 210. The movable contact component 22 includes a movable contact piece 221, a movable contact point 222, a movable contact rivet 223, The action rod 224 and the movable contact piece 225, the movable contact 222 is located at the bottom of the movable contact piece 221 and matches the static contact 211. The movable contact piece 221 is fixed to the static contact piece 210 through the movable contact rivet 223. The left end includes a touch point 2211 at the top, the action rod 224 is set at the top of the touch point 2211, and the movable contact piece 221 is driven by the action rod 224 through the touch point 2211, and the movable contact piece 225 is set at the movable point 2211.
