Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
As shown in Fig. 1, Fig. 3 and Fig. 4, embodiments provide a kind of switching device, including the first component 8,
Second component the 7, first positioning element the 6, second positioning element 5 and driving means 1.The one side of the first component 8 has
The drivening piece 83 slided for the pilot slide valve 9 or main slide valve 13 that drive cross valve, its another side has the first lobe 81；The
On the opposite face that the another side of two components 7 and the first component 8 is oppositely arranged, there is the second lobe 71, i.e. second
Component 7 is positioned at first component 8 side away from the first lobe 81.Realized by the rotation of the second component 7
First lobe 81 is alignd with the second lobe 71 and staggers；Driving means 1 drives the second component 7 to rotate；First is fixed
Position parts 6 are used for being switched to circumferentially positioned second component 7 during refrigerating state, and the first positioning element 6 positions the second auxiliary section
Part 7 rear drive equipment 1 stops operating；Second positioning element 5 is used for being switched to heat circumferentially positioned second component 7 during state
Rotating, the second positioning element 5 positions the second component 7 rear drive equipment 1 and stops operating.
In the present embodiment, drivening piece 83 drives the pilot slide valve 9 of cross valve to slide.It is understood that pilot slide valve 9
Slide in auxiliary pilot valve chamber 10.As shown in Figure 1, pilot slide valve 9 upward sliding is switched to refrigerating state, and pilot slide valve 9 is downward
Slide handover is to heating state, and switching device is positioned at the lower section of pilot slide valve 9.

Realize the first lobe 81 by the rotation of the second component 7 to align with the second lobe 71；Due to the first lobe 81 with
Second lobe 71 is alignd so that the total length that the second component 7 coordinates with the first component 8 increases so that first joins
The drivening piece 83 closing parts 8 drives pilot slide valve 9 upward sliding.When sliding to certain position on pilot slide valve 9, drive capillary tube
C ＇ and capillary tube D ＇ is connected by auxiliary pilot valve chamber 10, and capillary tube S ＇ and capillary tube E ＇ connection.First positioning element 6 is circumferentially positioned
Second component 7, so limit location the second component 7 rotate.The second component is positioned at the first positioning element 6
After 7, driving means 1 stops operating.Now, driving means 1 also can keep pilot slide valve 9 no longer to slide without power supply.Shadow part
It is divided into the coolant trend that compressor 17 exports.
Under the operation of compressor 17, the pressure in first piston chamber 11 is more than the pressure of the second plunger shaft 12, main slide valve 13
Move to the direction of the second plunger shaft 12, the S mouth of pipe of connection cross valve and the E mouth of pipe, and, the C mouth of pipe of cross valve and the D mouth of pipe lead to
Cross middle chamber 14 to connect, complete to switch the effect of cross valve.Fluid after compressor 17 compression is after the D mouth of pipe and the C mouth of pipe
Flowing into indoor set 15, the fluid through heat exchange flows back to compressor 17 after off-premises station 16 after the E mouth of pipe and the S mouth of pipe, is formed

7 rotate, and realize the first lobe 81 by the rotation of the second component 7 and stagger with the second lobe 71.S3: owing to first is convex
Play portion 81 to stagger with the second lobe 71 so that the total length that the second component 7 coordinates with the first component 8 reduces, and makes
The drivening piece 83 obtaining the first component 8 drives pilot slide valve 9 slide downward.S4: when pilot slide valve 9 is snapped down to certain position
Time, it being switched to heat recurrent state, driving means 1 stops operating.S5: air-conditioning runs to heat state, needs to be switched to refrigeration
State.S6: driving means 1 drives the second component 7 to rotate, and realizes the first lobe by the rotation of the second component 7
81 align with the second lobe 71.S7: owing to the first lobe 81 is alignd with the second lobe 71 so that the second component 7
The total length coordinated with the first component 8 increases so that the drivening piece 83 of the first component 8 drives pilot slide valve 9 upwards
Slide.S4: when sliding to certain position on pilot slide valve 9, is switched to kind of refrigeration cycle state, and driving means 1 stops operating.
Drivening piece 83 can also be made directly to drive the main slide valve 13 of cross valve to slide, and the principle controlling main slide valve 13 slip is same
On.
Wherein, switching device can arbitrarily be arranged, it is only necessary to guaranteeing staggers with the second lobe 71 in the first lobe 81 makes
Second component 7 and the first component 8 are relatively close.As it is shown in figure 1, in the present embodiment, the normal work of cross valve
Making under state, the first component 8 is positioned at above the second component 7, realizes the second component 7 by gravity and joins with first
Close parts 8 relatively close.Elastic device (such as spring) can also be set inside cross valve, by the elastic return of elastic device
Power makes drivening piece 83 have to the close restoring force of the second component 7.Such as the structure of the present embodiment, can be at pilot slide valve
Above in the of 9 and between the inner chamber upper wall in auxiliary pilot valve chamber 10, compression spring is set, drives the by the elastic restoring force of compression spring
One component 8 is close to the second component 7.
The switching device that the embodiment of the present invention provides, makes drivening piece 83 coordinate along first by the rotation of driving means 1
Parts 8 and the orientation campaign of the second component 7, and then drive pilot slide valve 9 or main slide valve 13 to slide, complete the shape that freezes
State and heat the switching of state.Further, when being switched to refrigerating state, the first circumferentially positioned second component of positioning element 6
7, driving means 1 stops operating, and the position of drivening piece 83 is also relatively fixed, it is not necessary to powers to driving means 1 and also can keep first
Slide guide valve 9 or main slide valve 13 no longer slide.In like manner, when being switched to heat state, the second positioning element 5 circumferentially positioned second is joined
Closing parts 7, driving means 1 stops operating, and the position of drivening piece 83 is also relatively fixed, it is not necessary to powers to driving means 1 and also can
Pilot slide valve 9 or main slide valve 13 is kept no longer to slide.By above-mentioned setting, it is only necessary to when switching refrigerating state and heating state
Need power supply, and without energising after having switched, save power consumption；And, it is ensured that air-conditioning power-off (accident power-off or pass
Close) restart rear cross valve and remain stationary, it is not necessary to again cross valve is switched over, reduce the loss of cross valve, be effectively increased
The service life of cross valve.
