Description

Beauty device with safety structure

technical field

The invention relates to a cosmetic device, in particular to a cosmetic device with a safety structure.

Background technique

There are many beauty devices on the market that use high pulsed light (Intense Pulsed Light, IPL) to care for the skin, such as hair removal devices, anti-spot wrinkle devices, and skin rejuvenation devices. These beauty devices are generally equipped with a xenon flash lamp as the IPL light source to emit pulsed strong light with a wavelength between 480nm and 1300nm to the skin surface; the IPL light source is set at the inner end of the probe, and the other end of the probe is covered with light-shielding material or filter material Cover to prevent damage to eyesight caused by strong pulsed light hitting the eyes of the user or anyone near the device when the device is in use. When using, first touch the probe to the skin surface that needs to be protected, and then press the button to start the light source, so that the light source irradiates the skin surface for a short time; then move the probe to the next skin surface that needs to be protected, and then press the button to start the light source, and so on. However, when using these cosmetic devices, it is generally necessary to move the probe multiple times within a larger skin surface range, and the user is easy to start the cosmetic device when the probe does not fully contact the skin surface between each movement, so that the pulse is strong. Light leaks out through the gap between the probe and the skin surface, posing a danger to the user or anyone near the device.

Contents of the invention

The purpose of the present invention is to overcome the shortcomings of the prior art and provide a cosmetic device with a safety structure that can prevent the light source from emitting light when the probe is not in full contact with the skin surface, thereby avoiding danger to the user or people near the device.

To achieve the above object, the present invention adopts the following technical solutions:

A cosmetic device with a safety structure, comprising: a housing, a probe disposed on the housing, a light source disposed at the inner end of the probe, a light source switch connected to the light source, a skin contact detection device disposed at the outer end of the probe, and the light source, the light source The central controller connected to the switch and the skin contact detection device; the skin contact detection device sends a confirmation signal to the central controller when the skin surface completely touches the outer end of the probe; the central controller drives the light source to emit light when it receives the confirmation signal and the light source switch is turned on .

When the skin contact detection device has a gap between the outer end of the probe and the skin surface, the skin contact detection device is in a standby state.

The housing of the cosmetic device is also provided with a skin contact indicator light, which is connected to the central controller, and the central controller drives the skin contact indicator light when receiving the confirmation signal, and controls the skin contact indicator light when the skin contact detection device is in a standby state. Stop glowing.

The light source can be a xenon flash lamp, which emits intense pulsed light with a wavelength between 480nm and 1300nm and an intensity between 2-5J/cm ² . The use of xenon flash as an IPL light source is an existing technology, not a new invention.

The skin contact detection device includes a capacitive sensor arranged along the periphery of the outer end of the probe. The outer end of the probe can be rectangular, and the skin contact detection device includes two capacitive sensors, each capacitive sensor is provided with a C-shaped electrode, and the two C-shaped electrodes are arranged opposite to each other to cover the entire perimeter of the outer end of the probe. Capacitive sensor is the prior art, but the present invention utilizes two C-shaped electrodes, and the light source of the beauty device can only emit light when both C-shaped electrodes are in contact with the skin, which can reduce false alarms while maintaining the sensing sensitivity.

The housing of the cosmetic device is also provided with a humidity sensor, which is connected with the central controller. The casing is also provided with a skin humidity display device connected with the humidity sensor to display the output of the humidity sensor.

The cosmetic device is also provided with a wireless transmission device, which is connected to the central controller, and the central controller sends the skin humidity sensed by the humidity sensor to an external device such as a mobile phone or an electronic computer through the wireless transmission device. The wireless transmission device may be, for example, a Bluetooth device, a Wi-Fi device, a 3G device, and the like.

The cosmetic device of the present invention operates as follows:

First, the user activates the beauty device. Before the user touches the outer end of the probe to the skin surface that needs to be treated, the skin contact detection device is in a standby state; when the user completely touches the outer end of the probe to the skin surface that needs to be treated, the skin contact detection device sends a confirmation to the central controller signal; after the central controller receives the confirmation signal, it will drive the skin contact indicator to emit light, indicating to the user that the light source can be activated to emit light; the user can then activate the light source switch to make the light source emit a short strong light, and if necessary, press the control button Key to adjust the intensity of the light. Then, the user moves the probe to the next skin surface that needs to be protected. When the probe leaves the skin surface, the skin contact detection device returns to the standby state, and the central controller controls the skin contact indicator light to stop shining, indicating to the user that it cannot be started. The light source emits light, even if the user activates the light source, the central controller does not send a confirmation signal to the central controller, so the central controller will not drive the light source to emit light; until the user touches the probe completely to the skin surface, the skin contacts the detection device Only then will a confirmation signal be sent to the central controller. After the central controller receives the confirmation signal, it will drive the skin contact indicator light to indicate to the user that the light source can be activated to emit light. It can be seen that if the outer end of the probe does not fully contact the skin surface, the light source will not emit light even if the user activates the light source, thereby preventing the light source from emitting light when the probe is not in full contact with the skin surface, and avoiding harm to the user or people near the device. pose a danger.

If the user needs to know the humidity of the skin surface, the humidity sensor can be touched to the skin surface, and the user can know the output of the humidity sensor through the skin humidity display device; if the humidity sensor shows that the skin is dry, the user can decide not to use the beauty device , so as not to cause damage to the skin. In addition, the data of skin humidity can also be sent to external devices such as mobile phones or electronic computers through wireless transmission devices.
