Description

Technical Field

[0001] The utility model specifically relates to a novel hair trimming device. Background Art

[0002] Hair trimming devices, such as razors, nose hair clippers, and hair trimmers, are generally used to remove hair on the skin or the surface of objects. Nowadays, with the changes in user needs, most users have more requirements for the functions of hair trimming devices. In response to this, current hair trimming devices have improved lighting, display, and start-up methods to make them multifunctional and meet the needs of different users. In addition, users also have more requirements for start-up methods, and pursue cooler start-up methods. Existing razors are usually electric, and there are many types of start-up switches for razors, such as button switches, toggle switches, and touch switches, and touch switches are cooler.

[0003] For an electric hair trimming device equipped with a touch switch, when using it, the user only needs to place the hand holding the hair trimming device on the touch sensing sheet to start the hair trimming device for use. However, it is found during use that when the user is taking or putting the hair trimming device, the user may accidentally touch the touch sensing sheet, causing the hair trimming device to be suddenly started. The suddenly started shaver may inadvertently cause harm to the user, so that the user cannot take or put the hair trimming device naturally and casually. The user must pay special attention to the touch sensing sheet and deliberately retract the hand to a position away from the touch sensing sheet to prevent the hair trimming device from being started by touching the touch sensing sheet. This brings great inconvenience to the use of the hair trimming device.

[0004] Moreover, for other cool starting methods, such as blowing, grip sensing, voice control, etc., the single control method often causes the hair trimming device to be triggered by mistake, which brings great inconvenience to the user. Utility Model Content

[0021] Figure 3 This is a logic block diagram of an embodiment (razor) of the utility model. DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] The hair trimming device of the present application may be a razor, barber scissors, nose hair scissors and other products, all of which are provided with a cover for protecting the blade head assembly. The present application takes a razor as an example for explanation.

[0025] As shown in the figure, a new hair trimming device comprises:

[0026] The hair trimmer body 2 is a shaver with normal functions, which is provided with a controller therein and has one or more starting modes of sound control, shaking control, and airflow control. When any starting mode is triggered, a first control signal will be output to the controller. The user generates the first control signal by making a sound, shaking the shaver or exhaling.

[0027] As for the voice control method, a voice dialogue model can be used, such as waking up the controller through a wake-up word, and then the controller acts through a specific startup instruction. Or, ordinary voice control can be directly used, that is, the sound can be generated to control it, and it can be set according to the use environment.

[0028] The shaking control can adopt the level sensor or gravity sensor, gyroscope sensor etc.

[0029] Airflow control can be achieved using an exhalation sensor, etc.

[0030] A cover body 1, which is used to cooperate with the hair trimmer body and cover the cutter head assembly 3 of the hair trimmer body, and which itself plays a role in protecting the cutter head assembly. In the present application, the cooperation action of the cover body and the hair trimmer body is output as a signal to obtain a second control signal, that is, a first trigger element 4 is provided at the position where the hair trimmer body and the cover body cooperate, and the first trigger element outputs the second control signal to the controller when and only when the cover body is separated from the hair trimmer body;

[0031] And the controller 5 outputs a driving signal for controlling the movement of the cutter head assembly according to the first control signal, that is, controls the movement of the motor 6, thereby driving the cutter head assembly to move, when and only when the second control signal is obtained.

[0032] That is, when the cover is covered on the hair trimmer body, the cover closes the first trigger element and is in a closed state. At this time, even if the user starts the shaver by starting mode, the shaver will not work; when the cover is removed, the first trigger element is disconnected, so that the controller is in a wake-up state. At this time, the motor is still in a closed state. When the user starts the shaver by starting mode, the motor can be turned on, thereby starting the shaver.

[0033] The first trigger element is a touch switch arranged at the matching position of the hair trimmer body and the cover body, that is, when the cover body is closed, the touch switch is pressed so that it is always in a closed state, and when the cover body is separated, different signals are output to control the controller. At the same time, the signal is a first priority signal, that is, subsequent signal processing can be performed only after obtaining this signal.

[0034] As another triggering method, the first triggering element includes a magnetic part arranged in the cover body and a Hall switch arranged at the cutter head assembly for cooperating with the magnetic part, and the Hall switch is electrically connected to the controller. At the same time, the cover body is directly magnetically matched with the hair trimmer body, and the magnetic part is used to cooperate with the Hall switch to realize the triggering of the signal.

[0035] That is, the second control signal is used as the dominant signal, that is, the controller can be in a normal working state only after obtaining the second control signal. When the controller does not receive the second control signal, it will not act when receiving other signals.

[0036] The cutter head assembly is detachably connected to the hair trimmer body. The detachable connection between the cutter head assembly and the hair trimmer body facilitates cleaning of the cutter head assembly. In order to avoid starting during the disassembly of the cutter head assembly, a second trigger element can be provided at the position where the cutter head assembly cooperates with the hair trimmer body. The second trigger element 7 outputs a third control signal to the controller for driving the controller to sleep or stop running when and only when the cutter head assembly is separated from the hair trimmer body.

[0037] The second trigger element can be a touch switch. When the cutter head assembly and the hair trimmer body are matched, the touch switch is triggered to output a third control signal. The third control signal causes the controller to sleep or stop running, thereby ensuring that the hair trimmer body will not be accidentally triggered during the separation process of the cutter head assembly.

[0038] A touch sensing area is provided at any position on the surface of the hair trimmer body, and a sensor sheet 8 electrically connected to the controller is provided inside the hair trimmer body at a position corresponding to the touch sensing area, and the sensor sheet outputs a fourth control signal to the controller when and only when the user touches the touch sensing area, and the priority of the fourth control signal is greater than the second control signal.

[0039] By setting the touch-sensitive area, it can play a role in safe display during sales display and avoid accidental triggering during the display process.

[0040] The cover is magnetically connected to the hair trimmer body and is fixed in a magnetic manner, which is more convenient during disassembly.

[0041] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
