Description

Technical Field

[0001] The utility model relates to a hair removal device circuit, in particular to a hair removal device circuit with a waterproof alarm function. Background Art

[0002] The existing hair removal device circuit mainly includes the following parts: microprocessor MCU: used to receive the user's operation signal to output a control signal to the execution circuit to turn the light source drive unit on or off; light source drive unit: connect or disconnect the power module and the light source according to the control signal; light source: used to emit intense pulsed light for hair removal.

[0003] There is a kind of hair removal device called a hair removal device with replaceable heads. The light source part of the hair removal device is made into a separate replaceable head of the hair removal device, which is then plugged into the main circuit part of the hair removal device through a plug. The advantage of this is that if multiple people (such as multiple people in a family need to use the hair removal device) want to use the hair removal device, they do not need to buy a hair removal device. They only need to buy a hair removal device body and buy multiple hair removal device replaceable heads. When each person uses it, they only need to take out their own hair removal device replaceable head to prevent cross infection.

[0004] However, since the replaceable head of the hair removal device is connected to the main body of the hair removal device through a plug and a socket, it is inevitable that the plug and the socket will be damp or wet during use, causing the main body to malfunction, and in serious cases, the main body will be burned. There is an urgent need in the market for a hair removal device with a replaceable head that can promptly remove moisture from the plug and / or the socket of the hair removal device. Utility Model Content

[0005] The utility model aims to solve the above-mentioned drawbacks and provides a hair removal device circuit with a waterproof alarm function which can timely remind the user when abnormal moisture appears in the plug and / or the socket of the hair removal device.

[0006] The technical scheme of the utility model is: to provide a hair removal device circuit with a waterproof alarm function, comprising a replaceable head part and a host part, wherein the replaceable head part comprises a plug and a light source connected to the plug; the host part comprises a socket, a light source driving unit, a waterproof detection unit, a display module, a microprocessor MCU and a working unit; the plug has a plug waterproof detection port, the socket has a socket waterproof detection port, after the plug is plugged into the socket, the plug waterproof detection port is electrically connected to the socket waterproof detection port; the socket waterproof detection port is connected to the waterproof detection unit; the light source driving unit, the waterproof detection unit and the display module are electrically connected to the microprocessor MCU respectively, and the light source driving unit is used to control the on or off of the light source; the microprocessor MCU pre-stores a normal voltage value of the waterproof detection port of the socket during normal use; when the plug is connected to the socket and turned on, the waterproof detection unit detects the real-time voltage value of the socket and the plug through the socket waterproof detection port and the plug waterproof detection port, when the real-time voltage value is lower than the pre-stored normal voltage value, the microprocessor MCU cuts off the power supply of the light source through the light source driving unit, and sends a warning signal to the user through the display module.

[0007] As an improvement to the present invention, the light source is an IPL light source or a laser light source.

[0008] As an improvement to the present utility model, the microprocessor MCU is a single chip microcomputer.

[0009] As an improvement to the present utility model, the light source driving unit is an electronic switch.

[0010] As an improvement to the present invention, the light source driving unit may be a MOS tube.

[0011] The utility model adopts the waterproof detection technology. The microprocessor MCU pre-stores the waterproof detection port voltage during normal use. After the power is turned on, the waterproof detection unit provides the detection voltage to the waterproof detection port. When there is moisture in the plug or socket, the impedance of the waterproof detection port to the ground is greatly reduced, resulting in the detection voltage being pulled down. The voltage is transmitted to the microprocessor MCU through the waterproof detection unit. The microprocessor MCU compares the voltage with the pre-stored waterproof detection port voltage during normal use. If the voltage is lower than the pre-stored waterproof detection port voltage during normal use, the microprocessor MCU believes that there is moisture in the plug or socket. The microprocessor MCU will cut off the power supply to the light source through the light source driving unit and send a warning signal to the user through the display module. In this way, the utility model has the advantages of protecting the product and timely reminding the user when the plug or socket of the hair removal device has abnormal moisture. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1The utility model is a circuit principle schematic diagram of an embodiment of the utility model. DETAILED DESCRIPTION

[0013] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0014] See also Figure 1 , Figure 1 Disclosed is a hair removal device circuit with a waterproof alarm function, comprising a replaceable head part 1 and a host part 2, wherein the replaceable head part 1 comprises a plug 3 and a light source 2 connected to the plug 3; the host part 4 comprises a host socket 5, a display module 6, a light source driving unit 7, a waterproof detection unit 8, a microprocessor MCU9 and a working unit 10; the plug 3 has a plug waterproof detection port 11, the socket 5 has a socket waterproof detection port 12, after the replaceable head plug 3 is plugged into the host socket 5, the plug waterproof detection port 11 is electrically connected to the socket waterproof detection port 12; the socket waterproof detection port 12, the display module 6 and the waterproof detection unit 8 are electrically connected to the microprocessor MCU9 respectively, the light source driving unit 7 is used to control the on or off of the light source 2; the microprocessor MCU9 pre-stores the voltage value of the socket waterproof detection port 12 during normal use, the replaceable head plug 3 and the host After the socket 5 is connected and turned on, the waterproof detection unit 8 supplies power to the socket waterproof detection port 12, and the socket waterproof detection port 12 transmits the real-time voltage value of the socket waterproof detection port 12 and the plug waterproof detection port 11 to the microprocessor MCU9 through the waterproof detection unit 8. When there is moisture in the plug 3 or the socket 5, the moisture impedance is very low, resulting in a significant reduction in the impedance between the socket waterproof detection port 12 and the plug waterproof detection port 11 and the ground, thereby causing the real-time voltage value to be significantly reduced. The real-time voltage value is transmitted to the microprocessor MCU9 through the waterproof detection unit 8, and the microprocessor MCU9 compares this voltage with the pre-stored voltage value. If it is determined that this real-time voltage value is less than the pre-stored normal voltage value, the microprocessor MCU9 determines that there is moisture in the interchangeable head plug 3 and / or the host socket 5, and the microprocessor MCU9 cuts off the power supply of the light source 2 through the light source driving unit 7, and sends a warning signal to the user through the display module 6.

[0015] Specifically, in the present embodiment, the microprocessor MCU9 is a single chip microcomputer, and the single chip microcomputer may be a single chip microcomputer of model ZX66F048 produced by Zhuoxinwei; the light source driving unit 7 may be an electronic switch; and the electronic switch may be a MOS tube.

[0016] During use, when the microprocessor MCU9 receives the real-time voltage value of the socket waterproof detection port 12 and the plug waterproof detection port 11, and judges that when the real-time voltage value is less than the pre-stored normal voltage value, the microprocessor MCU9 cuts off the power supply of the light source 2 through the light source driving unit 7, and sends a warning signal to the user through the display module 6.

[0017] At this time, after wiping or drying the replaceable head plug 3 and / or the host socket 5, the device can be turned on for use to avoid causing greater damage to the hair removal device.

[0018] In the present invention, the light source 2 is an IPL light source or a laser light source.

[0019] The IPL light source is also called Intense Pulsed Light, which is a filtered high-energy pulse light source. The spectral range of the IPL light source is generally 500-1200nm. It can be used on a hair removal device.

[0020] In the present invention, the laser light source needs to meet the following conditions when in use:

[0021] Safety certification: The laser light source needs to undergo multiple safety certifications, such as FDA / FCC / CE / RoHS, etc., to prove its safety and effectiveness.

[0022] Wavelength of pulsed light: The wavelength of the laser light source needs to be within an appropriate range, usually between 475-1200nm. The longer the wavelength, the stronger the penetration, the more light energy the hair follicles can absorb, and then convert it into heat energy, making the hair lose its regeneration ability, and the hair removal effect is better.

[0023] Energy density: The energy density of the laser light source also needs to be appropriate, generally between 2-5 joules. Too low energy density will affect the hair removal effect, while too high energy density may cause damage to the skin.

[0024] Safety assurance: The laser light source should have safety assurance, such as safety protection devices to prevent overheating or excessive skin damage.

[0025] In short, the laser light source used in hair removal devices needs to ensure its safety and effectiveness.
