Specific embodiment

The figures of Fig. 1 to 3 are referred to, the utility model is a kind of error-proof structure of power switch, and which includes：One body 10, should 10 surface of body is provided with a depressed part 11, and the depressed part 11 is a rounded face, and is provided with a hole 12 in 11 center of depressed part, And surrounding is then provided with least one first location division 13；One power switch 20, inside the body 10；One pressing piece 30, engaging In the depressed part 11 of the body 10,30 center of pressing piece is provided with a rotating shaft 31, the rotating shaft 31 be arranged in the hole 12 and with this Power switch 20 is corresponding, and the bottom surface of the pressing piece 30 is provided with least one second location division 32；And an elastic component 14, it is one Spring, is sheathed in the rotating shaft 31 and snaps in the hole 12；Wherein, when rotation, the pressing piece 30 makes those the second location divisions 32 After corresponding with those first location divisions 13, then the pressing piece 30 is pressed, make the rotating shaft 31 contradict the power switch 20 to open Or close the power switch 20, conversely, when rotate the pressing piece 30 make those second location divisions 32 not with those the first location divisions 13 it is corresponding when, then cannot press the pressing piece 30, and then make the rotating shaft 31 contradict the power switch 20, to avoid false touch The pressing piece 30 and be turned on and off the power switch 20.

Describe in detail, please referring initially to Fig. 3, those first location divisions 13 have the first projection 131 and the first groove 132, and Those second location divisions 32 have the second projection 321 and the second groove 322, wherein first projection 131, first groove 132, Second projection 321 and second groove 322 are arcuation.

Then, refer to shown in Fig. 4, in order to avoid user or other articles press the pressing piece 30 by mistake, cause the electricity Source switch 20 is turned on and off, and user need to rotate the pressing piece 30, make those second location divisions 32 not with those first positioning Portion 13 is corresponding, i.e. the first groove of the second projection 321 of the second location division 32 and the second groove 322 and the first location division 13 132 and first projection 131 for staggering not corresponding, make the rotating shaft 31 contradict the electricity so as to avoid the pressing piece 30 depressed Source switch 20；Conversely, referring to shown in Fig. 5, if user is intended to start or close the power switch 20, user need to rotate this and press Casting die 30, makes those second location divisions 32 corresponding with those first location divisions 13, i.e. the second projection 321 of the second location division 32 And second groove 322 it is corresponding with the first groove 132 of the first location division 13 and the first projection 131 respectively, then user The pressing piece 30 is pressed, is made the rotating shaft 31 contradict the power switch 20 and is started or close, and when user is no longer to the pressing After part 30 exerts a force, the pressing piece 30 is subject to the elastic force of the elastic component 14 and returns back to a positioning.

Therefore the utility model provides a kind of error-proof structure of power switch really, rotating presser can be passed through so as to second First location division of location division and body cannot corresponding combination, and mutually fasten, start or close to avoid false touch pressing piece Close power supply.However, the utility model can be applied not only to carry-along water element generation device, in the quick feelings of development in science and technology now Under condition, electric equipment products miscellaneous are constantly weeded out the old and bring forth the new, as long as those electric equipment products need to carry out power supply by pressing keys Be turned on and off with the utility model connected applications, and then false touch pressing piece can be avoided and started or closed power supply.

In sum, preferred possible embodiments only of the present utility model, it is non-therefore limit to patent of the present utility model Scope, changes with the equivalent structure carried out by the utility model specification and schema content such as, manages practical with being contained in In new scope, Chen Ming is given in conjunction.
