DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Please refer to Figure 1-3 ;

[0027] The switch structure described in the utility model has an automatic reset function, which can realize the switching between some circuits, that is, to realize the triggering and automatic closing of some uncommon functions, and specifically includes a base 111 and a toggle member 121; the base 111 and the toggle member 121 in this embodiment can be provided with corresponding limiting structures for limiting the movement trajectory of the toggle member 121, or the movement trajectory of the toggle member 121 can be limited by an external fixing member, which is not limited here, but the final effect is that the base 111 and the toggle member 121 can slide relative to each other; at least one elastic member 13 is provided between the two, and the two ends of the elastic member 13 are respectively in contact with the base 111 and the toggle member 121, and multiple elastic members are provided on both sides of the base 111. The step groove 14, wherein the step groove 14 can be integrally formed with the base 111, or can be a part of an external part, which is not limited here; the step arms 122 used in conjunction with the step groove 14 are connected to both sides of the toggle member 121, and the step arms 122 are elastic. In order to facilitate the step arms 122 to achieve reciprocating motion in the step groove 14, arc convex points are specifically provided on the side of the step arms 122, and the corresponding step groove 14 adopts an arc-shaped wave design. A lever 123 is also provided at one end of the toggle member 121, and at least one resistance switch 15 is provided on the side of the lever 123. Of course, the resistance switch 15 should be electrically connected to the control circuit board. In this embodiment, the resistance switch 15 can be a micro switch;

[0028] Preferably, the end of the lever 123 is in a pointed cone shape, and the corresponding abutting portion of the abutting switch 15 is provided with an inclined surface adapted thereto.

[0029] Assuming that there is only one contact switch 15, and when the contact switch 15 is in the on state, the entire circuit is in the off state, then in the initial state, the lever 123 contacts the contact switch 15, so that the contact switch 15 is in the on state, and the functional circuit is in the off state. At the same time, the section arm 122 is engaged with the section groove 14 to fix the relative position of the base 111 and the toggle member 121 to avoid accidental touch. Of course, the section groove 14 has one level at this time; at this time, the lever 123 is located at the end away from the elastic member 13;

[0030] When it is necessary to trigger the function of the device, it is necessary to manually push the toggle member 121 and the base 111 to slide relative to each other, so that the segment arm 122 is disengaged from the segment groove 14, and the toggle rod 123 is separated from the resistance switch 15, and the elastic member 13 is compressed at the same time. At this time, the resistance switch 15 is in the disconnected state, the functional circuit is triggered, and the corresponding hidden function can be used. In order to maintain the continuous working state of the functional circuit, it is necessary to manually apply external force to maintain the current relative state of the toggle member 121 and the base 111. After the function is used up, the external force applied to the toggle member 121 is canceled, and the toggle member 121 is pushed in the reverse direction under the action of the elastic member 13 to reset, so that the segment arm 122 is re-engaged with the segment groove 14, and at the same time, the toggle rod 123 is again abutted against the resistance switch 15, and the functional circuit is closed.

[0031] The utility model fixes the initial state of the base 111 and the toggle member 121 by setting the joint arm 122 and the joint groove 14, so that the functional circuit is in a closed state and accidental touch is avoided. When the hidden function needs to be used, it is necessary to continuously apply external force to the toggle member 121 to disengage the joint arm 122 from the joint groove 14. After use, the elastic member 13 is used to push the toggle member 121 to move in the reverse direction to reset and close the functional circuit, which effectively avoids the situation that people forget to turn off the function.

[0032] It should be noted that the above-mentioned embodiment is only used to illustrate the operating principle of the automatic reset switch structure 1. The lever 123 can also be set at one end close to the elastic member 13, and its operation and reset method are the same as those in the above-mentioned embodiment. The difference is that when the resistance switch 15 and the lever 123 are separated, it is in the initial state, and the functional circuit needs resistance to be turned on to be triggered, that is, after the toggle member 121 is pushed, the lever 123 abuts against the resistance switch 15, so that the resistance switch 15 is turned on, and under the action of the elastic member 13, the toggle member 121 is reset, the lever 123 is separated from the resistance switch 15, and the functional circuit is turned off; in addition, the lever 123 can also be set on one side of the toggle member 121, and similarly, the resistance switch 15 is also set on one side. The specific principle and operation method are the same or similar to those in the above-mentioned embodiment, which is only a variation of the scheme and should belong to the protection scope of this application.

[0033] The utility model further describes that the lever 123 is disposed at an end away from the elastic member 13;

[0034] In this embodiment, there are two conflict switches 15, through which a gear position and a hidden function can be set. They are arranged side by side or staggered on both sides along the movement direction of the lever 123, and the corresponding section groove 14 has two levels. In the initial state, the lever 123 is in contact with the two conflict switches 15, that is, the two conflict switches 15 are in the on state, and the device is in the off state. At the same time, the section arm 122 is engaged with one of the slots of the section groove 14;

[0035] When in use, the push-toggle member 121 is pushed to slide relative to the base 111, so that the section arm 122 is stuck in the second slot, and the lever 123 is separated from one of the conflict switches 15, that is, one of the conflict switches 15 is in the disconnected state, and the other conflict switch 15 is still in the on state. At this time, the device is in a normal working mode. It should be noted that at this time, there is a situation where the elastic member 13 is compressed or not compressed. When the elastic member 13 is compressed, since the moving distance of the toggle member 121 is very short, that is, the amount of compression of the elastic member 13 is very small, the force generated by the elastic member 13 is not enough to push the toggle member 121 to reset. At this time, the working mode is maintained. The solution when the elastic member 13 is not compressed will be described in the subsequent implementation mode.

[0036] When it is necessary to switch the mode, continue to push the toggle member 121 to slide relative to the base 111, so that the segment arm 122 is disengaged from the segment groove 14, and the toggle rod 123 is also separated from the other resistance switch 15, and the elastic member 13 is compressed at the same time. At this time, both resistance switches 15 are in the disconnected state, and the circuit is switched to the hidden function. After releasing the toggle member 121, the toggle member 121 is pushed in the reverse direction under the action of the elastic member 13, so that the segment arm 122 is re-engaged with the segment groove 14, and the toggle rod 123 is in contact with one of the resistance switches 15, and the normal mode is restored.

[0037] The utility model further describes the relationship between the base 111 and the toggle member 121;

[0038] The base 111 is provided with two limiting bosses 112 along the running direction of the toggle member 121, and the bottom of the toggle member 121 is provided with a slide groove 124 that cooperates with the limiting boss 112. The mutual cooperation between the limiting boss 112 and the slide groove 124 can limit the running direction of the toggle member 121 without deviation.

[0039] Furthermore, when there is a height difference between the conflict switches 15 and the toggle member 121 , a gradient frame 125 is provided between the toggle member 121 and the lever 123 , and the gradient frame 125 moves the lever 123 downward to correspond to the conflict switch 15 .

[0040] In order to limit the sliding distance of the toggle member 121 relative to the base 111, the base 111 is provided with a limit slide groove 115 along the running direction of the toggle member 121, and a limit slider matching the limit slide groove 115 is provided at the bottom of the toggle member 121. The limit slider is always placed in the limit slide groove 115. When the toggle member 121 is pushed to a certain position, the limit slider will contact the edge of the limit slide groove 115 and cannot slide further, thereby achieving the effect of position limitation.

[0041] Furthermore, the toggle member 121 includes a sliding frame 1211 and a toggle block 1212. The sliding frame 1211 is provided with a plurality of clamping holes 1213. The bottom of the toggle block 1212 is provided with a buckle 1214. The buckle 1214 is clamped with the clamping hole 1213 and extends out of the clamping hole 1213 to be placed in the limiting slide groove 115. In this embodiment, the buckle 1214 replaces the function of the limiting slide block.

[0042] The utility model further describes the arrangement of the elastic member 13;

[0043] Two receiving grooves 114 with notches 113 are provided at the end of the base 111. The elastic member 13 is placed in the receiving groove 114. Two top ribs 126 are provided at the bottom of the toggle member 121. The top ribs 126 correspond to the notches 113. There are two situations based on this structure.

[0044] In the first embodiment, the top rib 126 is in contact with the elastic member 13 in the initial state, and the top rib 126 compresses the elastic member 13 after the toggle member 121 is pushed. Based on the above embodiment, the section groove 14 has two-level grooves. When the side arc convex point of the section arm 122 is inserted into the second groove, the top rib 126 compresses the elastic member 13 from the notch 113, but the elastic member 13 is only slightly compressed, which is not enough to push the toggle member 121 to move in the opposite direction.

[0045] In the second embodiment, in the initial state, the top rib 126 and the elastic member 13 are in a separated state. Based on the above embodiment, the node groove 14 has two-level slots. When the side arc protrusion of the node arm 122 is inserted into the second slot, the top rib 126 only enters the notch 113 and contacts the elastic member 13. After further pushing the toggle member 121 to slide, the top rib 126 compresses the elastic member 13. In this embodiment, the elastic member 13 adopts a spring with a large elastic coefficient. After releasing the toggle member 121, the elastic member 13 can push the toggle member 121 to slide in the reverse direction, so that the side arc protrusion of the node arm 122 is inserted into the slot of the node groove 14.

[0046] Based on the above two embodiments, the receiving groove 114 has two symmetrical arrangements, and the top ribs 126 also have two.

[0047] The utility model also discloses a hair dryer 2 including the above-mentioned automatic reset switch structure 1. The hair dryer 2 of the utility model and the automatic reset switch structure 1 are based on the same concept, produce the same technical effect, can realize high-power operation of the blower, and can automatically reset to a normal state after use. For details, please refer to the implementation method of the automatic reset switch structure 1, and the implementation method of the hair dryer 2 will not be described in detail here.
