Description

Technical Field

[0001] The utility model relates to the field of daily necessities, and particularly relates to a shaving pressure sound feedback component and a razor. Background Art

[0002] The performance of a skin treatment device (such as a razor) depends on the pressure applied to the skin.

[0003] For example, European Patent EP 3513927 A1 discloses a razor that has a sensor for measuring the shaving pressure applied to the blade holder and has an illumination device for indicating a subset of information to the user, such as a multicolor LED. In one embodiment, when the sensor detects that the shaving pressure is optimal, the illumination device illuminates a first color (such as green), and when the sensor detects that the shaving pressure is above the optimal range, the illumination device illuminates a second color (such as yellow or red). The notification to the user of the comparison of the optimal shaving pressure sensed by the sensor with a high or low shaving pressure can change over time based on learning the user's preferences and shaving behavior.

[0004] Also, for example, US Patent US2019 / 0061183A1 discloses an electric razor that includes a sensor for detecting the pressure or force with which the working head of the razor presses against the skin. The razor also includes a control unit and a light emitter to indicate to the user the detected pressure or force. The control unit can change the color of the emitted light according to the detected pressure or force. For example, green light can indicate a relatively low force, yellow light can indicate an average force, and red light can indicate a relatively high force. Advantageously, the color can be changed gradually or continuously to give precise feedback.

[0005] However, the applicant has found that ordinary pressure light feedback has limitations in actual use. When holding and operating, it is not easy for the user to observe the corresponding light color and must rely on observation devices such as a mirror. Only by observing on the mirror can the user know the current pressure feedback color. When carrying it out, when there is a lack of observation conditions, the user cannot know the current pressure value from the color. Summary of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a shaving pressure sound feedback component and a razor.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope protected by the present utility model.

[0030] It should be noted that all directional indications in the embodiments of the present utility model, such as up, down, left, right, front, back,...) are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0031] The present utility model discloses a shaving pressure sound feedback component, which is mainly arranged in the body component of the razor. During use, when the razor head abuts against the user's skin, it can give a trigger signal, enabling the shaving pressure sound feedback component to detect the load current of the motor used to drive the movement of the razor head in real time, and dividing the range interval of the load current into multiple threshold regions according to the converted pressure. Then, when the detected load current enters the corresponding threshold region, a corresponding prompt sound is emitted. The prompt sound can be beeps of different frequencies or beeps of different numbers (such as one beep, two beeps, etc.) or directly perform voice broadcast, which can be set according to requirements.

[0032] The shaving pressure sound feedback component includes a razor head 100, a trigger switch 220, a control board 230, and a sound output unit 240. The razor head is mainly used to determine when it abuts against the user's skin during use to trigger the trigger switch, which serves as the trigger factor for pressure feedback.

[0033] The razor head 100 can be a single - head razor, a double - head razor, or a multi - head razor, which is set according to needs. When it cooperates with the body component and abuts against the user's skin, it will generate a certain amount of travel, and this travel should be sufficient to trigger the trigger switch.

[0034] The trigger switch 220 is used to output a trigger signal when it is determined that the razor head 100 abuts against the user's skin during use. In this embodiment, a tactile switch is adopted, and in some other embodiments, a metal reed or other switch methods can also be used.

[0035] The control board 230, based on the trigger signal, obtains the load current of the motor linked to the razor head and outputs output information including this load current. It detects the load current of the motor in real - time by setting a corresponding current detection circuit and outputs a corresponding control output according to the real - time load current.

[0036] The sound output unit 240 is used to provide the user with the output information of the load current determined by the control board 230. The sound output unit 240 is a buzzer or a speaker, and it has several levels of output information with different volumes, frequencies, or voices. The sound output unit 240 outputs corresponding output information according to the different control outputs received, realizing different feedback for different pressure values and realizing the soundification of pressure feedback.

[0037] Among them, the control board 230 has several levels of control outputs, including:

[0038] When the load current determined by the control board 230 is within the range between a first threshold and a second threshold higher than the first threshold, a first output signal is provided;

[0039] When the load current determined by the control board 230 is higher than the second threshold, a second output signal different from the first output signal is provided;

[0040] When the load current determined by the control board 230 is lower than the first threshold, a third output signal is provided.

[0041] In this embodiment, three output signals can be adopted to respectively give prompts for too little pressure, suitable pressure, and too much pressure. In some other embodiments, multiple thresholds can also be added to achieve more status prompts, such as further subdividing too little pressure or subdividing too much pressure, etc., which are set according to the number of required prompts.

[0042] There are four trigger switches 220, which are respectively located at the front, rear, left, and right positions, and trigger members 110 for triggering the trigger switches 220 at different positions are respectively provided at the bottom of the razor head 100.

[0043] Combined with the design of the floating frame provided in the body assembly, it can be realized that when the razor head floats in different directions, the trigger switch can be triggered. Compared with the previous single-trigger form, the trigger condition of the pressure feedback is more extensive and the feedback is more reliable. In the previous single-trigger form, the trigger condition can only be formed when the force is applied forward or backward. When the force is applied in the other three directions, there will be no pressure feedback, which has limitations.

[0044] In this embodiment, the trigger switch 220 is arranged on the trigger board 210, and the trigger board 210 is arranged in the body assembly 200 of the razor. The axis of the razor head 100 is perpendicular to the trigger board 210. The trigger switch is fixed by the trigger board, and the axis B of the razor head is perpendicular to the plane A of the trigger board, so that when it floats in different directions, the trigger switch corresponding to the direction can be triggered. At the same time, the trigger stroke of each trigger switch is the same, so that the pressure feedback in different directions has consistency.

[0045] The specific circuit of the control board of this application can refer to the publicly disclosed patent CN221736223U applied by the applicant. The main difference from this publicly disclosed patent is that the feedback method of this application adds sound feedback, and four trigger switches in four directions are added to the trigger switch. At the same time, the four trigger switches are connected in parallel, so that any one of the trigger switches can be triggered to realize independent control.

[0046] In this embodiment, light feedback can also be retained, that is, it is also provided with a light output unit 270, and the first output signal, the second output signal, and the third output signal each include light outputs with corresponding different colors. The light feedback has corresponding aesthetic performance. Appropriately retaining it can improve the grade of the whole product.

[0047] In this embodiment, a display unit is also provided for information display.

[0048] The display unit includes a digital tube 260 arranged on a display board 250, and the display board 250 is perpendicular to the trigger board 210 and is electrically connected to the trigger board 210.

[0049] The corresponding information is displayed by setting the digital tube 260, and then digital display is performed on the body assembly. During use, intuitive understanding can be achieved through this data display.

[0050] The present utility model further provides a shaver, which comprises a body assembly 200, and the body assembly 200 is provided with the shaving pressure sound feedback assembly described in any one of the above. The bottom of the shaver head is set as a connecting piece, which is inserted into the interior of the body assembly and is detachably connected to the internal connecting piece. At the same time, the connecting piece is fixedly arranged in the body assembly through a floating frame, so as to realize the floating of the shaver head by means of the floating frame. At the same time, a corresponding trigger 110 is arranged at the bottom of the floating frame, and the travel generated by the trigger when the shaver head abuts against the user's skin is used to trigger the trigger switch in the corresponding direction.

[0051] The embodiments should not be regarded as limitations of the present utility model, but any improvements made based on the spirit of the present utility model should be within the protection scope of the present utility model.
