Description

Blower switch

Technical Field

The utility model relates to the field of switches, in particular to a switch of a blower.

Background

At present, the common blower switch in the market often adopts the spring and the steel ball to realize the switching of the blower switch action of the 5-pole 3 loop, but the switch of the structure has larger volume, more parts and high cost, and under the condition of the same size, the mode of adopting the spring and the steel ball can not realize the separation of different electric loops.

Disclosure of Invention

The present utility model provides a blower switch to solve at least one of the above technical problems.

To solve the above-described problems, as an aspect of the present utility model, there is provided a blower switch including: the base is provided with a first fixed conducting strip, a second fixed conducting strip and a third fixed conducting strip, the base is also provided with a first movable conducting spring piece and a second movable conducting spring piece, the first movable conducting spring piece comprises a first movable contact arm, a second movable contact arm and an elastic positioning arm arranged between the first movable contact arm and the second movable contact arm, the first movable contact arm is correspondingly arranged with the first fixed conducting strip, the second movable contact arm is correspondingly arranged with the second fixed conducting strip, the second movable conducting spring piece is correspondingly arranged with the third fixed conducting strip, the operating handle is arranged on the base through the cover, and the bottom of the cover is provided with a slope matched with a protruding part on the first movable conducting spring piece and the second movable conducting spring piece and a plurality of positioning grooves matched with positioning protrusions on the elastic positioning arm.

Preferably, the number of the positioning grooves is three.

By adopting the technical scheme, the utility model utilizes the first movable conductive elastic sheet and the second movable conductive elastic sheet to replace the traditional switch action switching of the blower which can be realized by adopting the spring and the steel ball, thereby reducing the number and the size of parts, realizing automatic production, reducing the consumption of resources and lowering the production cost.

Detailed Description

The following describes embodiments of the utility model in detail, but the utility model may be practiced in a variety of different ways, as defined and covered by the claims.

As one aspect of the present utility model, a blower switch, in particular a 5 pole 3 loop blower switch, is provided, which is a switching device for switching on and off an electrical circuit in a blower loop.

The blower switch in the utility model comprises: the base 1 is provided with a first fixed conducting strip 4, a second fixed conducting strip 5 and a third fixed conducting strip 6, the base 1 is also provided with a first movable conducting spring 7 and a second movable conducting spring 8, the first movable conducting spring 7 comprises a first movable contact arm 9, a second movable contact arm 10 and an elastic positioning arm 11 positioned between the first movable contact arm 9 and the second movable contact arm 10, the first movable contact arm 9 is correspondingly arranged with the first fixed conducting strip 4, the second movable contact arm 10 is correspondingly arranged with the second fixed conducting strip 5, the second movable conducting spring 8 is correspondingly arranged with the third fixed conducting strip 6, the operating handle 3 is arranged on the base 1 through the cover 2, and the bottom of the cover 2 is provided with a slope 13 matched with a protruding part 12 on the first movable conducting spring 7 and the second movable conducting spring 8 and a plurality of positioning grooves 15 matched with the elastic positioning arm 11. Preferably, the number of the positioning slots 15 is three.

The first movable conductive spring piece 7, the first fixed conductive piece 4 and the second fixed conductive piece 5, and the second movable conductive spring piece 8 and the third fixed conductive piece 6 are respectively and correspondingly arranged, so that two loops which can be controlled by the operating handle 3 are formed.

In operation, the control circuit is opened and closed by a user manually pulling the operating handle 3. When the handle 3 is operated during sliding, the slope 13 at the bottom of the handle is matched with the convex parts 12 on the first movable conductive spring piece 7 and the second movable conductive spring piece 8, so that the first movable conductive spring piece 7 and the second movable conductive spring piece 8 are contacted with corresponding fixed conductive pieces to realize conduction; when the slope 13 leaves the protruding portion 12, the first movable conductive spring 7 and the second movable conductive spring 8 are disconnected from the fixed conductive sheet.

Meanwhile, when the positioning projection 14 formed as a triangular projection on the elastic positioning arm 11 falls into the positioning groove 15 at the bottom of the operating handle 3, the opening and closing position of the operating handle 3 can be locked. The cover plays a role in preventing the internal structure of the switch from being exposed and ensuring the use safety.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
