CN201156491Y - Liquid level control switch - Google Patents

Abstract

The utility model discloses a liquid level control switch using liquid flow to control the switching of the circuit, which comprises a rotatable annular sealed container. The sealed container is filled with conducting liquid and insulating liquid with different specific gravity which can separate up and down and fixed with a positive terminal and a negative terminal which are alternatively connected with the conducting liquid and the insulating liquid when the annular sealed container rotates. The liquid level control switch realizes the switching of the circuit by using the flow of the liquid.

Description

A kind of liquid level control switch

(1) technical field

The utility model relates to a kind of electric switch, a kind of specifically liquid level control switch that utilizes liquid flow control circuit break-make.

(2) background technology

At present, existing switch has standard machinery formula contact switch, optoelectronic switch, air switch etc., but the switch of the break-make that flows control circuit of utilizing liquid is seldom arranged, and liquid control switch be we can say and also have certain blank on market.

(3) summary of the invention

The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of and utilizes the low-angle upset of object to make liquid flow realize the liquid level control switch of the automatic road of circuit break-make.

The utility model is finished by the following technical programs:

The utility model liquid level control switch, comprise the rotatable annular closed container that proportion difference, the conducting liquid that can separate up and down and iknsulating liquid are housed, be fixed with positive terminal and the negative terminal that when the annular closed container rotates, alternately is connected on the described annular closed container with conducting liquid and iknsulating liquid.The utility model utilizes the different of conducting liquid and iknsulating liquid proportion, and the rotation by the position of annular closed container of the conducting liquid that separates under action of gravity and iknsulating liquid alternately realizes and being connected of positive negative terminal, thus the break-make of realization circuit.

The beneficial effects of the utility model are: utilize liquid flow to realize the break-make of control circuit.

(4) description of drawings

Fig. 1 disconnects schematic diagram for the utility model switch;

Fig. 2 is the utility model switch closure schematic diagram.

Among the figure: 1, iknsulating liquid, 2, conducting liquid, 3, the annular closed container, 4, positive terminal, 5, negative terminal.

(5) embodiment

Below in conjunction with accompanying drawing the utility model is specified.

Fig. 1, Fig. 2 are respectively structural representation of the present utility model, include iknsulating liquid 1, conducting liquid 2, annular closed container 3, positive terminal 4, negative terminal 5.When switch at horizontal level, as shown in Figure 1, conducting liquid 2 disconnects with binding post 4,5, and is non-conductive; When switch flipped an angle a, as shown in Figure 2, conducting liquid 2 can be connected binding post 4,5, began conduction; When switch turned over conducting liquid 2 scopes, circuit was insulated liquid 1 again and disconnects.

Claims (1)

1. liquid level control switch, it is characterized in that: comprise the rotatable annular closed container that proportion difference, the conducting liquid that can separate up and down and iknsulating liquid are housed, be fixed with positive terminal and the negative terminal that when the annular closed container rotates, alternately is connected on the described annular closed container with conducting liquid and iknsulating liquid.
