Description

Technical Field

[0001] The utility model relates to the technical field of mask beauty instruments, in particular to a wearing detection circuit and a wearing detection device for a mask beauty instrument. Background Art

[0002] Existing mask beauty instruments are provided with laser lights. When the mask beauty instrument is worn on the human face, the laser lights emit laser light to the human skin on the face. Through the light modulation effect of the laser (i.e., the biological stimulation effect), that is, after the laser enters the human skin, it will affect the cell organelles in the human skin, realizing the beauty function of the human skin.

[0003] Existing mask beauty instruments usually use light sensors for wearing detection. Specifically, the light sensors on the mask beauty instrument emit light to the human skin and receive the light reflected by the human skin. Based on the time interval from emitting light to receiving light, the distance between the mask beauty instrument and the human skin is detected. When the mask beauty instrument is close to the human skin to be less than a preset distance, the laser lights of the mask beauty instrument are turned on; when the mask beauty instrument is far from the human skin to be greater than or equal to the preset distance, the laser lights of the mask beauty instrument are turned off.

[0004] However, during the process of turning on the laser lights, the light sensors on the mask beauty instrument will also receive the laser light reflected back by the human skin, which easily causes errors when the light sensors detect the distance between the mask beauty instrument and the human skin, resulting in mis-triggering when turning off the laser lights of the mask beauty instrument.

[0048] The embodiments of the technical solution of the present utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present utility model more clearly, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0050] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0051] Existing mask beauty devices usually use light sensors for wearing detection. Specifically, the light sensors on the mask beauty device emit light to the human skin and receive the light reflected by the human skin. Based on the time interval from emitting light to receiving light, the distance between the mask beauty device and the human skin is detected. When the mask beauty device approaches the human skin to less than a preset distance, the laser lamp of the mask beauty device is turned on; when the mask beauty device moves away from the human skin to greater than or equal to the preset distance, the laser lamp of the mask beauty device is turned off.

[0052] However, during the process of turning on the laser lamp, the light sensor on the mask beauty device will also receive the laser reflected by the human skin, which is likely to cause errors when the light sensor detects the distance between the mask beauty device and the human skin, resulting in false triggering when turning off the laser lamp of the mask beauty device. Therefore, the present utility model provides a wearing detection circuit for a mask beauty device, which can effectively avoid the false triggering of the laser lamp of the mask beauty device, as Figure 1 shown, specifically as follows:

[0053] In the present utility model, a wearing detection circuit is used to detect whether a mask beauty device is worn or removed. The mask beauty device is provided with a laser lamp, and the laser emitted by the laser lamp is used to beautify the human skin. That is, after the mask beauty device is worn on the human face, the laser emission port of the laser lamp faces the human skin of the human face, and the laser is emitted to the human skin through the laser emission port to beautify the human skin.

[0054] Among them, the wearing detection circuit includes: a contact detection module and a controller; the controller can be a microcontroller MCU or a central processing unit CPU, and specific details are not limited here. The contact detection module includes: a touch sensing chip and a detection contact; the touch sensing chip can be a single-channel self-calibrating touch sensing chip AM01B_W or a single-button capacitive touch sensing chip NT01A, and specific details are not limited here. The touch sensing chip is used to collect the trigger signal of the detection contact to determine whether the detection contact is in contact with the human skin. The detection contact is arranged on the side of the mask beauty device close to the human skin when worn, that is, the detection contact is arranged on the side facing the human skin during the wearing process of the mask beauty device; and the detection contact is connected to the touch sensing chip.

[0055] The detection contact can be a shrapnel-type contact (that is, when the shrapnel-type contact is in contact with the human skin, after being squeezed by the human skin, the shrapnel of the shrapnel-type contact contacts the base, and the capacitance of the shrapnel-type contact will change; when the shrapnel-type contact is not in contact with the human skin, it is not squeezed by the human skin, the shrapnel of the shrapnel-type contact is separated from the base, and the capacitance of the shrapnel-type contact does not change. That is, the touch sensing chip can determine whether the shrapnel-type contact is in contact with the human skin by detecting the capacitance change of the shrapnel-type contact), or it can be an electrode probe contact (that is, when the electrode probe contact is in contact with the human skin, an electric current loop will be formed between the electrode and the human skin, and there will be a current output at this time; when the electrode probe contact is not in contact with the human skin, there will be no current output. That is, the touch sensing chip can determine whether the detection contact is in contact with the human skin by collecting whether there is a current output from the electrode probe contact), and specific details are not limited here.

[0056] The touch sensing chip, connected to the controller, is used to send a contact signal to the controller when the detection contact is in contact with the human skin, and send a non-contact signal to the controller when the detection contact is not in contact with the human skin. It can be understood that each touch sensing chip is connected to a corresponding detection contact. The touch sensing chip collects the trigger signal of the corresponding detection contact to determine whether the detection contact is in contact with the human skin. If the detection contact is in contact with the human skin, it is determined that the mask beauty device is worn completely, and a contact signal is sent to the controller; if the detection contact is not in contact with the human skin, it is determined that the mask beauty device is not worn, and a non-contact signal is sent to the controller.

[0057] Among them, the controller is connected to the laser lamp and is configured to turn on the laser lamp when receiving a contact signal and turn off the laser lamp when receiving a non-contact signal. That is, the controller can accurately control the laser lamp to turn on when the mask beauty device is in contact with the human skin and turn off when the mask beauty device is not in contact with the human skin.

[0058] It can be seen that in the present utility model, the wearing detection circuit of the mask beauty device includes: a contact detection module and a controller; the contact detection module includes: a touch sensing chip and a detection contact; the detection contact is arranged on the side of the mask beauty device close to the human skin when worn, and the detection contact is connected to the touch sensing chip; the touch sensing chip is connected to the controller and is configured to send a contact signal to the controller when the detection contact is in contact with the human skin and send a non-contact signal to the controller when the detection contact is not in contact with the human skin; the controller is connected to the laser lamp and is configured to turn on the laser lamp when receiving the contact signal and turn off the laser lamp when receiving the non-contact signal. By turning on the laser lamp when the detection contact is in contact with the human skin and turning off the laser lamp when the detection contact is not in contact with the human skin, the influence of the laser emitted by the laser lamp can be avoided during wearing detection, and the situation of mis-triggering of the laser lamp of the mask beauty device can be effectively avoided. At the same time, the wearing or falling off of the mask beauty device can be accurately detected, and the wearing detection circuit is simple and easy to implement with low cost.

[0059] Further, when the touch sensing chip is the single-channel self-calibrating touch sensing chip AM01B_W, as Figure 2 shown, the contact detection module further includes: a first resistor R1, a second resistor R2, a third resistor R3, a first capacitor C1, and a second capacitor C2; wherein, the single-channel self-calibrating touch sensing chip includes: an induction output terminal OUT, a power negative input terminal GND, a touch sensing terminal KEY, an output level selection terminal VGM, a power positive input terminal VDD, and a mode selection terminal HMD; it can be understood that the output level selection terminal VGM is used to output a high-level or low-level effective mode selection. When the output level selection terminal VGM is connected to a high level, the induction output terminal OUT outputs a low-level effective signal, and when the output level selection terminal VGM is connected to a low level, the induction output terminal OUT outputs a high-level effective signal; the mode selection terminal HMD is used to perform a hold / sync mode selection. When the mode selection terminal HMD is connected to a high level, the induction output terminal OUT is in a hold output mode, and when the mode selection terminal HMD is connected to a low level, the induction output terminal OUT is in a sync output mode.

[0060] Among them, the positive power input terminal OUT is connected to the power supply VCC, one end of the first resistor R1, and one end of the first capacitor C1; the other end of the first resistor R1 is connected to the output level selection terminal VGM, the other end of the first capacitor C1 is grounded, and the mode selection terminal HMD is grounded through the third resistor R3. That is, at this time, the output level selection terminal VGM is connected to a high level, the induction output terminal OUT outputs a low level effectively, the mode selection terminal HMD is connected to a low level, and the induction output terminal OUT is in the synchronous output mode. One end of the second resistor R2 is connected to the detection contact GP1, the other end of the second resistor R2 is connected to one end of the second capacitor C2 and the touch induction terminal KEY, and the other end of the second capacitor C2 and the negative power input terminal GND are grounded; the induction output terminal OUT is connected to the controller.

[0061] In the above contact detection module, when the detection contact GP1 contacts the human skin, the level signal output by the induction output terminal OUT of the single-channel self-calibrating touch induction chip AM01B_W will change from high level to low level; after the controller receives the low level signal (i.e., the contact signal), it will control the laser lamp to turn on, and the laser lamp emits laser. Only when the detection contact keeps contacting the human skin (i.e., when wearing is completed), the level signal output by the induction output terminal OUT remains low level all the time, and the laser lamp remains on; when the face mask beauty instrument falls off, the level signal output by the induction output terminal OUT changes from low level to high level. After the controller receives the high level signal (i.e., the non-contact signal), it will control the laser lamp to turn off.

[0062] Furthermore, the output level selection terminal VGM of the single-channel self-calibrating touch induction chip AM01B_W can be set to be connected to a low level, and the induction output terminal OUT outputs a high level effectively; that is, corresponding to Figure 2 In [description], the contact detection module further includes: a second resistor R2, a third resistor R3, a first capacitor C1, and a second capacitor C2; among them, the single-channel self-calibrating touch induction chip AM01B_W includes: an induction output terminal OUT, a negative power input terminal GND, a touch induction terminal KEY, an output level selection terminal VGM, a positive power input terminal VDD, a mode selection terminal HMD; the positive power input terminal OUT is connected to the power supply VCC and one end of the first capacitor C1; the other end of the first capacitor C1 is grounded, and the mode selection terminal HMD and the output level selection terminal VGM are grounded through the third resistor R3; one end of the second resistor R2 is connected to the detection contact GP1, the other end of the second resistor R2 is connected to one end of the second capacitor C2 and the touch induction terminal KEY, and the other end of the second capacitor C2 and the negative power input terminal GND are grounded; the induction output terminal OUT is connected to the controller.

[0063] In the above contact detection module, when it is detected that the contact GP1 touches the human skin, the level signal output by the induction output terminal OUT of the single-channel self-calibrating touch sensing chip AM01B_W will change from low level to high level; after the controller receives the high-level signal (i.e., the contact signal), it will control the laser lamp to turn on, and the laser lamp emits laser. Only when the detection contact continuously touches the human skin (i.e., when wearing is completed), the level signal output by the induction output terminal OUT remains high level all the time, and the laser lamp remains on; when the face mask beauty instrument falls off, the level signal output by the induction output terminal OUT changes from high level to low level, and after the controller receives the low-level signal (i.e., the non-contact signal), it will control the laser lamp to turn off.

[0064] Further, the touch sensing chip can also be a single-button capacitive touch sensing chip NT01A. As Figure 3 shown, the contact detection module further includes: a first resistor R1, a second resistor R2, a first capacitor C1, a charge collection capacitor Comd, and a sensitivity capacitor Cdc; it can be understood that the smaller the sensitivity capacitor Cdc is, the higher the sensitivity of the single-button capacitive touch sensing chip NT01A is. Among them, the single-button capacitive touch sensing chip includes: an induction output terminal OUT, an induction capacitor input terminal CIN1, a sensitivity capacitor input terminal CDC, a charge collection capacitor input terminal CMOD, a power negative input terminal GND, and a power positive input terminal VDD. The charge collection capacitor input terminal CMOD is connected to one end of the charge collection capacitor Comd, and the other end of the charge collection capacitor is grounded; the power positive input terminal VDD is connected to the power supply VDD, the power negative input terminal GND is grounded, and a first capacitor C1 is connected between the power positive input terminal VDD and the power negative input terminal GND; the sensitivity capacitor input terminal CDC is connected to one end of the sensitivity capacitor Cdc, and the other end of the sensitivity capacitor Cdc is grounded; the induction capacitor input terminal CIN1 is connected to the detection contact (touch button) through the first resistor R1; the induction output terminal OUT is connected to the controller through the second resistor R2.

[0065] In the above contact detection module, when the detection contact (touch button) touches the human skin, the level signal output by the induction output terminal OUT of the single-button capacitive touch sensing chip NT01A changes from high level to low level; after the controller receives the low-level signal (i.e., the contact signal), it will control the laser lamp to turn on, and the laser lamp emits laser. Only when the detection contact continuously touches the human skin (i.e., when wearing is completed), the level signal output by the induction output terminal OUT remains low level all the time, and the laser lamp remains on; when the face mask beauty instrument falls off, the level signal output by the induction output terminal OUT changes from low level to high level, and after the controller receives the high-level signal (i.e., the non-contact signal), it will control the laser lamp to turn off.

[0066] Further, the contact detection module includes: a plurality of touch sensing chips, each touch sensing chip having a corresponding detection contact, and the plurality of detection contacts corresponding to the plurality of touch sensing chips are disposed on the side of the mask beauty device close to the human skin when worn. Specifically, the controller is configured to turn on the laser light when receiving contact signals sent by the plurality of touch sensing chips, and turn off the laser light when receiving a non-contact signal sent by any one of the plurality of touch sensing chips. That is, when the detection contacts of all the touch sensing chips are in contact with the human skin, the controller receives the contact signals sent by all the touch sensing chips, and then turns on the laser light for beauty treatment; if the detection contact of any one touch sensing chip is not in contact with the human skin and the controller does not receive the contact signals sent by all the touch sensing chips, the laser light is turned off. By providing a plurality of detection contacts on the mask beauty device and turning on the laser light only when the plurality of detection contacts are all in contact with the human skin, the situation of mis-triggering when the laser light is turned on can be effectively avoided.

[0067] As Figure 5 shown, the detection contact GP1 corresponding to the touch sensing chip U1 and the detection contact GP2 corresponding to the touch sensing chip U2; the detection contact GP1 corresponding to the touch sensing chip U1 can be disposed on the left side of the mask of the mask beauty device, and the detection contact GP2 corresponding to the touch sensing chip U2 can be disposed on the right side of the mask of the mask beauty device, as Figure 4 shown. At this time, only when both the detection contact GP1 and the detection contact GP2 remain in contact with the human skin, the detection signal DET1 sent by the touch sensing chip U1 and the detection signal DET2 sent by the touch sensing chip U2 always remain at a low level. At this time, the controller controls the laser light to turn on.

[0068] Further, an eye opening is provided on the mask beauty device, and the eye opening is directly opposite to the human eyes when the mask beauty device is worn. It can be understood that the laser light of the mask beauty device is disposed in other areas except the eye opening. The wearing detection circuit turns on the laser light after the mask beauty device is worn. At this time, the human eyes are directly opposite to the eye opening of the mask beauty device, and the laser emitted by the laser light is not irradiated on the human eyes; and the laser light is turned off after the mask beauty device falls off; which can avoid the radiation hazard of the laser to the human eyes when the laser light is turned on.

[0069] Further, the wearing detection circuit further includes a control button; the control button is disposed on a side of the mask beauty instrument away from the human skin when worn, and the controller is connected to the laser lamp through the control button. The control button is used to disconnect the connection between the controller and the laser lamp (at this time, the controller cannot control the laser lamp), or close the connection between the controller and the laser lamp (at this time, the controller can control the laser lamp). That is, the connection between the controller and the laser lamp can be manually operated by pressing the control button. For example, pressing it for the first time disconnects the connection between the controller and the laser lamp, and pressing it for the second time closes the connection between the controller and the laser lamp, realizing the manual operation of the connection between the controller and the laser lamp. It can avoid the abnormality of the wearing detection circuit. For example, when the contact detection module detects an error or the controller fails, the laser lamp emits laser uncontrollably, further effectively avoiding the radiation hazard of the laser to the human eye.

[0070] The present invention also provides a wearing detection device for a mask beauty instrument, and the wearing detection device includes the above-mentioned wearing detection circuit.

[0071] In the present invention, the terms "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The term "plural" means two or more unless otherwise clearly defined.

[0072] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features.
