For example, the right end of the first clamping plate 1 and the right end of the second clamping plate 2 are hinged to each other, the left ends of the two are open ends, and a user applies an acting force to enable the first clamping plate 1 and the second clamping plate 2 to rotate relatively, so that the open ends are closed, and the operations of clamping hair and straightening hair by heating are completed.

In the present embodiment, at least one of the first clamping plate 1 and the second clamping plate 2 is provided with a sensing member 4 and a triggering member 6 (for example, the sensing member 4 and the triggering member 6 may be provided in the second clamping plate 2). The sensing piece 4 is movably arranged in the second clamping plate 2 and connected with the control chip, the sensing piece 4 moves relative to the triggering piece 6 and contacts with the triggering piece 6, after the sensing piece 4 contacts with the triggering piece 6, triggering is completed, after the sensing piece 4 is triggered, a triggering signal can be sent to the control chip, and the control chip feeds back the received triggering signal to a user through the feedback part.

Of course, according to actual needs, trigger piece 6 and sensing piece 4 can be through trigger mode, opto-coupler trigger mode, electromagnetic trigger mode or mechanical trigger mode and produce the trigger signal after accomplishing the trigger, and control chip can set up in splint or locate the outside of splint, provided that can guarantee that control chip and sensing piece 4 and feedback portion's connection.

In the conventional hair straightener, the hair is not clamped when the applied force is small, so that the hair is not heated sufficiently and escapes from the clamping space, and the applied force is too large, so that the hair is damaged by pulling or burning through the hair. Compared with the traditional hair straightener, the hair straightener provided by the embodiment of the utility model can acquire feedback whether the acting force applied by a user is proper or not in the process of operating the first clamping plate 1 and the second clamping plate 2, so that the user can conveniently adjust the acting force according to the current situation, the applied acting force just accords with the current operation of straightening all the clamped hair, and meanwhile, the situation that the hair is damaged due to hair strain or hair burn-through can be prevented.

Of course, the feedback part may be one or both of a voice feedback part and a text feedback part according to actual needs. Preferably, the feedback part is a voice prompt and/or a display screen, that is, the control chip feeds back the trigger signal to the user in a voice mode through the voice prompt and/or in a text display mode through the display screen, wherein the strength is proper (or improper).

When the feedback received by the user is proper, continuing to execute the hair straightening operation with the proper force; when the feedback received by the user is 'unsuitable' the applied force can be increased or decreased appropriately, so that the hair has better straightening effect.

It should be noted that, the suitability of the force may be obtained by comparing the force value fed back by the control chip according to the received trigger signal with the threshold value, and the control function of the control chip and the feedback function of the feedback portion are both conventional technical contents in the art, and are not the protection emphasis of the present utility model, and the present utility model focuses on implementing the feedback function of the applied force through the connection relationship of the sensing element 4, the trigger element 6, the control chip and the feedback portion.

In some embodiments, the hair straightener further comprises a pressing plate 5, the pressing plate 5 can move along with the sensing piece 4, a through hole for the triggering piece 6 to pass through is formed in the pressing plate 5, and the triggering piece 6 contacts with the sensing piece 4 after passing through the pressing plate 5.

It should be noted that the number of through holes on the pressing plate 5 may be set according to the number of contacts in the trigger member 6, provided that each contact can be ensured to pass through the through hole on the pressing plate 5 one by one when the pressing plate 5 and the sensing member 4 move.

The second clamping plate 2 is provided with an induction element 4, a triggering element 6, a pressing plate 5 and a control chip.

In some embodiments, the second clamping plate 2 further comprises a housing 9, the housing 9 is used for carrying and mounting the sensing element 4, the triggering element 6, the pressing plate 5 and the control chip, and the housing 9 is provided with a receiving groove 10 for receiving the triggering element 6.

During assembly, the trigger piece 6 is placed in the accommodating groove 10 of the shell 9, and then the pressing plate 5 and the sensing piece 4 are stacked above the trigger piece 6 in sequence.

Furthermore, a first elastic member 7 is abutted between the trigger member 6 and the housing 9, and the first elastic member 7 is used for providing an elastic force to the trigger member 6, so that the trigger member 6 has a tendency to move towards the sensing member 4 or the first clamping plate 1. This will allow the trigger 6 to return to the original position under the action of the first elastic member 7 when the force of the user is reduced or eliminated.

Of course, according to actual needs, the first elastic member 7 is specifically a spring, the number of the springs is consistent with the number of contacts of the triggering member 6, and a limit post for sleeving and limiting the springs is arranged at the bottom of each contact of the triggering member 6, so that one end of the spring can be sleeved at the bottom of the triggering member 6, and the other end of the spring is abutted to the shell 9.

In some embodiments, the second clamping plate 2 further includes a second elastic member 8, two ends of the second elastic member 8 respectively abut against the housing 9 and the sensing member 4, and the second elastic member 8 is configured to provide an elastic force to the sensing member 4, so that the sensing member 4 has a tendency to move away from the triggering member 6. This will allow the sensing member 4 to return to its original position under the action of the second elastic member 8 when the force of the user is reduced or removed.

In some embodiments, the number of the second elastic members 8 is two, the two second elastic members 8 are respectively located at two sides of the trigger member 6, and the heights of the two second elastic members 8 are different.

Of course, according to actual needs, the second elastic member 8 is specifically a silica gel pad, and the silica gel pad has elasticity, when the sensing member 4 is pressed down, the silica gel pad is elastically deformed, and applies upward elastic force to the sensing member 4 and the components above the sensing member, so that the sensing member 4 is restored to the initial position when the acting force is reduced or eliminated, and the triggering state of the sensing member 4 and the triggering member 6 is released.

In some embodiments, the second clamping plate 2 further includes a plate body 3, where the plate body 3 may be an aluminum plate, the aluminum plate is capable of conducting heat, the plate body 3 is movably disposed on the housing 9, the sensing element 4 is disposed on an inner side of the plate body 3, and the plate body 3 is used to drive the sensing element 4 to move relative to the triggering element 6 when the first clamping plate 1 and the second clamping plate 2 are closed. When the first clamping plate 1 and the second clamping plate 2 are closed, a force is exerted on the aluminum plate, so that the induction piece 4 and the pressing plate 5 act.

In this way, under the action of the force applied by the user, the plate body 3, the sensing piece 4 and the pressing plate 5 move downwards until the triggering piece 6 protrudes out of the pressing plate 5 and contacts with the sensing piece 4, triggering is completed (electrical triggering, optocoupler triggering, electromagnetic triggering, mechanical triggering and the like can be achieved), a triggering signal is sent to the control chip, and the control chip feeds back the triggering signal to the user through voice and/or a display screen to enable the strength to be proper.

In some embodiments, the trigger 6 comprises at least two contacts, any adjacent two contacts being spaced apart, and the height of one of the at least two contacts being different from the height of the other.

It will be appreciated that the lower contact point may be set as a warning trigger, so that the purpose of this setting is to make the user's operation safer, that is, when the user continues to increase the force, the lower warning trigger protrudes out of the pressure plate 5 and contacts the sensing element 4 to complete triggering, and the control chip feeds back the warning signal to the user, prompting the user that the force is too strong, the hair will be damaged, and the force needs to be reduced.

The following will specifically describe the contact as three or two.

When the number of the contacts is three, the middle contacts are warning triggers, the heights of the contacts at the two sides of the warning triggers are larger than those of the warning triggers, namely, the heights of the contacts at the two sides of the warning triggers are the same and larger than those of the warning triggers, so that the contacts at the two sides of the warning triggers can be triggered firstly when the first clamping plate 1 and the second clamping plate 2 are closed, that is, the contacts at the two sides of the warning triggers firstly contact the sensing piece 4 to complete triggering when the first clamping plate 1 and the second clamping plate 2 are closed, and in this state, the sensing piece 4 sends a triggering signal to the control chip, and the control chip feeds the triggering signal back to a user with proper strength through voice and/or a display screen. Then, if the user continues to increase the operation force, the contact point (warning trigger, lower position) in the middle protrudes out of the pressing plate 5 and contacts with the sensing piece 4 to complete triggering, the control chip feeds back a warning signal to the user, prompts the user to forcefully increase, damages hair and needs to reduce the force.

When the number of contacts is two, the height of the contact far from the hinge position (left side) of the first clamping plate 1 and the second clamping plate 2 is smaller than the height of the contact near the hinge position (right side) of the first clamping plate 1 and the second clamping plate 2, namely the left side contact is a warning trigger, and the right side contact is a common trigger.

It should be noted that, since the point of application of force is usually on the left side (open end) of the hair straightener during use, the force on the right side of the plate 3 is slightly smaller than the force on the left side, and therefore the contact on the left side is slightly lower than the contact on the right side. Therefore, when the first clamping plate 1 and the second clamping plate 2 are closed, the right contact contacts the sensing piece 4 to trigger, in this state, the sensing piece 4 sends a trigger signal to the control chip, and the control chip feeds the trigger signal back to a user through voice and/or a display screen to enable the user to have proper strength. After that, if the user continues to increase the operation force, the left contact protrudes out of the pressing plate 5 and contacts with the sensing piece 4 to complete triggering, the control chip feeds back a warning signal to the user, prompts the user to use too hard, damages the hair and needs to reduce the force.

It should be noted that in this specification relational terms such as first and second are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.
