The specific embodiment
Below with reference to accompanying drawing and combine embodiment to specify the utility model.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
The angle control power cutoff mechanism of present embodiment is used for collapsible electric heater, and shown in Fig. 1 to 2, collapsible electric heater comprises first supporter 10 and second supporter 20 that is provided with rotationally with respect to first supporter 10.Particularly, link together through two hinges between first supporter 10 and second supporter 20, on first supporter 10 and second supporter 20, first heat-generating units and second heat-generating units are set respectively.Preferably, first heat-generating units and second heat-generating units are Electric radiant Heating Film.
The angle control power cutoff mechanism of present embodiment mainly is included in and controls the switch of electric heater outage and the Control Component 32 of gauge tap energising and outage when the folding angle of electric heater reaches certain angle.In the present embodiment, switch has adopted normally closed switch 31.But the utility model is not limited to use normally closed switch, for example as long as the concrete structure of Control Component 32 is made adaptability design, also can use normal open switch etc.
Switch is fixedly set on first supporter 10, is electrically connected with first heat-generating units and second heat-generating units respectively, and switch 31 comprises the trigger part of Switch main body 313 and gauge tap 31 energisings and outage.And Control Component 32 is used to control trigger part; Control Component 32 comprises first state that makes switch 31 energisings and second state that makes switch 31 outages; Angle between second supporter 20 and first supporter 10 is during greater than predetermined angular; Control Component 32 is in first state, and when the angle between second supporter 20 and first supporter 10 was less than or equal to predetermined angular, Control Component 32 was in second state.Therefore; When electric heater is folded to security standpoint that the angle that makes two heat-generating units is less than or equal to design and is predetermined angular; Electric heater can be realized automatic outage; Effectively prevented because the situation that electric heater is still switched on and used when electric heater folded into the security standpoint that is less than or equal to design, prevented that the electric heater local temperature that causes thus is too high and influence the service life and the Electrical Safety of electric heater, also prevented injury or other accident to the user that possibly cause thus.
Preferably, predetermined angular can be set to the arbitrary value between 45 ° to 135 °.Like this, promptly can guarantee electric heater outage before folding, the angle that changes slightly in the time of also can preventing the user because of non-folding operations such as mobile electric heaters between second supporter 20 and first supporter 10 causes electric heater mistake pass.For example, in the present embodiment with the predetermined angular setting for 90 °.
Particularly, cam-operated comprises first pivot 322, first manoeuvre portion 323, second pivot 324 and second manoeuvre portion 325.First pivot 322 is arranged on first supporter 10 rotationally, and cam 321 is fixed on first pivot 322 coaxially.First manoeuvre portion 323 comprises first hub switch side and first sliding end that is oppositely arranged, and first hub switch side is fixedly arranged at first pivot 322.Second pivot 324 is arranged on second supporter 20 rotationally.Second manoeuvre portion 325 comprises second hub switch side and second sliding end that is oppositely arranged, and second hub switch side is fixedly arranged at second pivot, 324, the second sliding ends and is mounted slidably with respect to first sliding end.
In the present embodiment, first sliding end be sleeve, second sliding end of second manoeuvre portion 325 is provided with sleeve with matching.Extremely shown in Figure 4 like Fig. 1; First manoeuvre portion 323 and second manoeuvre portion 325 all are set to the flat box body structure that section is a U-shaped; Second hub switch side that vertical portion 325 is hemed with invisible stitches in first hub switch side of first manoeuvre portion 323 and second is a curved portions, is convenient to follow the first or second fixing separately pivot and rotates with respect to corresponding first or second supporter; First sliding end is that vertical section is the sleeve of rectangle, and the vertical section of second sliding end also is a rectangular configuration, but undersized is in first sliding end, and second sliding end stretches into first sliding end, and can in the tube-in-tube structure that first sliding end forms, be free to slide.
Cam-operated above structure has guaranteed when second supporter 20 rotates with respect to first supporter 10; The angle of cam 321 relative switch shrapnels 311 changes; Also promptly the relative position of first profile or second profile and switch shrapnel 311 changes, thereby realizes the control to the trigger part of switch.Certainly, cam-operated also is not limited to above concrete structure, for example, also can being slidingly connected between first manoeuvre portion and second manoeuvre portion be changed into hinged etc.
As shown in Figs. 3-4, the trigger part of normally closed switch 31 comprises switch contact 312 and switch shrapnel 311.Switch contact 312 is positioned on the Switch main body 313 and from the surface of Switch main body 313 to be given prominence to.Switch shrapnel 311 comprise the stiff end that fixedly installs with Switch main body 313 and with the stiff end opposed free ends; Switch contact 312 is between stiff end and free end and be in switch shrapnel 311 first side in the face of Switch main body 313; Cam and is in second side of switch shrapnel 311 back to Switch main body 313 between free end and switch contact 312.
From above description, can find out; The utility model the above embodiments have realized following technique effect: because angle control power cutoff mechanism has been installed on first supporter of collapsible electric heater and second supporter; When electric heater is folded to the angle that makes two heat-generating units and is less than or equal to the security standpoint of design; Electric heater cuts off the power supply automatically; The situation that electric heater is still switched on and used when having prevented that effectively electric heater folded into the security standpoint that is less than or equal to design, thus prevented that the electric heater local temperature that causes thus is too high and influenced the service life and the Electrical Safety of electric heater, and prevented to cause thus injury or other accident to the user.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
