Description

TECHNICAL FIELD

[0001] The utility model relates to micro electromagnetic valve technical field, concretely is a kind of micro two-in-one pulse electromagnetic valve. BACKGROUND

[0002] Micro electromagnetic valve is a kind of electromagnetic valve with small size. It is an industrial equipment controlled by electromagnetism, belongs to actuator, and is used to control the on-off, flow direction and the like of fluid.

[0003] Micro electromagnetic valve is usually composed of electromagnetic coil, valve core, valve seat and the like. When electromagnetic coil is electrified, electromagnetic force is generated, drives valve core to move, to change the opening or closing state of valve, to realize the control of fluid (such as gas, liquid).

[0004] The micro electromagnetic valve on current market only has single air inlet and air outlet, that is, one air inlet and one air outlet. When the equipment needs to control multiple air paths, multiple electromagnetic valves can only be selected to be used simultaneously.

[0005] In order to maintain the normally open or normally closed state, the micro electromagnetic valve on current market needs to be continuously powered. This design brings two main problems: first, continuous power supply leads to power waste, and battery capacity must be increased accordingly.

[0006] Secondly, continuous power supply makes the coil work continuously, and the temperature rises rapidly, so that the electromagnetic valve cannot be applied to various application scenarios in high-temperature state.

[0007] Therefore, based on the above technical problems, it is necessary for the person skilled in the art to develop a micro two-in-one pulse electromagnetic valve. UTILITY MODEL CONTENT

[0008] The utility model aims at providing a micro two-in-one pulse electromagnetic valve to solve the problems raised in the background art.

[0013] As a preferred technical scheme, the left air hole and the right air hole are used for allowing both ends to be subjected to external air pressure, so that the normally open or normally closed function can be realized without using a reset spring and without requiring continuous power supply of the coil.

[0014] As a preferred technical scheme, the left lower air pipe and the right lower air pipe are respectively connected with the left air hole and the right air hole, and are used for guiding air into or out of the electromagnetic valve, so as to realize circulation and control of two-way air.

[0015] Compared with the prior art, the micro two-in-one pulse electromagnetic valve has the following beneficial effects:

[0016] The left air hole and the right air hole are arranged, so that the core is subjected to the balanced pressure of external air pressure at both ends in the power-off state of the electromagnetic valve, the normally open or normally closed state is maintained, continuous power supply is not required, the power consumption of the electromagnetic valve is greatly reduced, and the corresponding battery capacity is reduced.

[0017] The electromagnetic valve does not require continuous power supply, the temperature of the coil rises slowly, and the electromagnetic valve can be applied to various application scenarios with low temperature rising speed.

[0018] Meanwhile, the left lower air pipe, the right lower air pipe and the right upper air pipe are designed skillfully, so that the micro two-in-one pulse electromagnetic valve not only realizes accurate control of air, but also is more functional, and can meet more complex control requirements. In addition, the buffer gasket and the sealing ring are arranged, so that the working noise of the electromagnetic valve is reduced.
