Power makes drivening piece 83 have the restoring force close to the second component 7.It, can be in pilot slide valve such as the structure of the present embodiment
Compressed spring is set between 9 tops and the inner cavity upper wall of auxiliary pilot valve chamber 10, drives the by the elastic restoring force of compressed spring
One component 8 is close to the second component 7.
Switching device provided in an embodiment of the present invention, by the rotation of driving device 1 so that drivening piece 83 cooperates along first
The orientation campaign of component 8 and the second component 7, and then pilot slide valve 9 or main slide valve 13 is driven to slide, complete refrigeration shape
State and the switching for heating state.Also, when being switched to refrigerating state, circumferentially positioned second component of the first positioning element 6
7, driving device 1 stops operating, and the position of drivening piece 83 is also relatively fixed, without being also able to maintain elder generation to the power supply of driving device 1
Slide guide valve 9 or main slide valve 13 no longer slide.Similarly, when being switched to heating state, the second positioning element 5 circumferentially positioned second is matched
Component 7 is closed, driving device 1 stops operating, and the position of drivening piece 83 is also relatively fixed, without also can to the power supply of driving device 1
Pilot slide valve 9 or main slide valve 13 is kept no longer to slide.Pass through above-mentioned setting, it is only necessary to just when switching refrigerating state and heating state
It needs to power, and saves electricity consumption without being powered after the completion of switching；Also, it ensure that air-conditioning powers off (accident power-off or pass
Close) restart rear four-way valve and remains stationary, it no longer needs to switch over four-way valve, reduces the loss of four-way valve, effectively increase
The service life of four-way valve.
