Description

Depilatory instrument

Technical Field

The application relates to the technical field of beauty care products, in particular to a depilating instrument.

Background

The depilatory instrument irradiates light with specific wavelength to the surface of human skin to generate heat on the surface of the human skin, so that hair follicles on the human skin are necrotized by absorbing sufficient light energy, and the hair shedding effect is achieved. When the depilating instrument is used for depilating a human body, the quartz lamp tube and the light-gathering cover outside the quartz lamp tube can instantly generate high-energy heat, so that the depilating instrument needs to have strong heat dissipation performance, otherwise, the local high temperature of the depilating instrument can cause the machine to melt, the machine is damaged, and the use safety risk is caused; on the other hand, the light emitted by the depilating device itself has burning and pain sensations, so that the pain sensation needs to be relieved by the "ice sensation", and the refrigeration assembly generating the "ice sensation" also needs to dissipate heat.

The existing depilatory instruments in the market have the function of ice feeling and are mostly refrigerated by using semiconductors. The refrigerating component of the scheme is a semiconductor refrigerating piece (also called a TEC refrigerating piece), and when the refrigerating component works, one end of the semiconductor refrigerating piece is a cold surface, and the reverse surface is a hot surface. When the refrigerating sheet works, if the heat of the hot surface is conducted out more quickly, the cold surface is stronger, the ice compress effect is better, and the body feeling of the depilating instrument is better. The cold surface of the refrigeration sheet is attached to the cold compressing part, and the hot surface is attached to the heat conducting component; when the depilating instrument works, the cold of the cold surface is transferred to the cold compress part, so that the skin is cooled when the cold compress part is contacted with the skin, the heat of the hot surface is transferred to the heat conducting component, and the heat radiating mechanism conducts the heat of the heat conducting component to the air outside the depilating instrument.

The cold compress part of the market depilator with the ice feeling is mainly divided into the following two parts: one is that a metal (or ceramic) cold compress piece surrounding a light outlet is adopted, the cold surface of a refrigerating sheet is attached to the cold compress piece, and the outer side of the cold compress piece is attached to the skin to enable the skin in contact with the cold compress piece to generate an 'ice feeling'; the other is that the light-emitting part is used as a cold compress piece, the cold surface of the refrigerating piece is attached to the transparent crystal of the light-emitting part, and the transparent crystal is in contact with the skin to enable the skin to generate an 'ice feeling'.

In the first depilatory apparatus adopting the cold compress piece surrounding the light outlet, the skin facing the light outlet still generates certain burning sensation in the depilatory process; the second type of hair removal device using the light emitting portion as the cold compress member has a poor ice compress effect because the light waves irradiate the light emitting port through the transparent crystal and heat the transparent crystal at the same time, thereby counteracting the ice of the refrigerating sheet.

The housing 10 is further provided with an air inlet 14 and an air outlet 15, respectively, for allowing external (cold) air to enter the housing 10 and internal (hot) air to exit the housing 10. In the illustrated embodiment, the air inlet 14 is formed on the second housing 12, and the air outlet 15 is formed on the first housing 11 and the second housing 12 near the nozzle cover 13. The housing 10 is further provided with a power supply port 17, and the power supply port 17 leads to the power supply connecting base 70 for supplying power to the depilation instrument 100 by an external power supply.

Referring to fig. 4, the epilating assembly 20 is disposed in the housing 10 and includes an emitter 21, a reflective mask 22, an emitter support 23, and a filter 24. The emitter 21 is disposed in the reflection light-collecting cover 22, and both ends of the emitter 21 penetrate through the lamp tube holes on both sides of the reflection light-collecting cover 22 and are fixed by the emitter support frames 23 from both ends, respectively. The filter 24 is disposed at the front (light-emitting direction) opening of the reflective light-collecting cover 22 to filter the light emitted from the emitter 21 and leave the red wave with a wavelength of over 640 NM.

The red light emitted by the emitter 21 and filtered by the filter 24 is emitted to the skin of the human body through the light-emitting channel to remove hair from the skin of the human body.

Referring to fig. 5 to 8, the cooling module 40 is disposed at the front end of the hair removal module 20, and includes a cold compress sheet 41, a cold conduction plate 42, a cold compress piece 43, a transparent crystal 44, a heat insulation sheet 45, and a cooling bracket 46, wherein the cold surface of the cold compress sheet 41 is attached to the cold conduction plate 42, the cold conduction plate 42 is attached to the cold compress piece 43, the transparent crystal 44 is embedded in the cold compress piece 43 through the cold conduction plate 42, and the front end surfaces of the cold compress piece 43 and the transparent crystal 44 are attached to the skin of the user. The cold compress plate 41 and the light-transmitting crystal 44 are embedded and mounted on the refrigeration bracket 46, the cold compress 43 is mounted on the refrigeration bracket 46, and the cold guide plate 42 is clamped and fixed between the cold compress 43 and the refrigeration bracket 46.

Specifically, the cold guide plate 42 is made of a material with a high thermal conductivity coefficient, and the cold of the cold compress refrigeration sheet 41 is quickly and uniformly guided onto the cold compress piece 43. The cold conducting plate 42 is provided with a transparent crystal through hole 421 and a cold conducting plate mounting hole 422. The transparent crystal through hole 421 is opened in the middle of the cold conducting plate 42 corresponding to the installation position of the transparent crystal 44, so that the transparent crystal 44 installed on the cooling bracket 46 can pass through. The cold conducting plate mounting holes 422 are distributed around the transparent crystal through hole 421 for matching with the cold dressing 43 and the refrigeration bracket 46 for mounting and fixing. In other embodiments, the cold plate 41 may directly engage the cold dressing 43, i.e., the cold conduction plate 42 may be omitted.

The cold compress 43 is made of a material having a high thermal conductivity such as metal or ceramic, and provides a cold feeling to the skin in contact therewith. The cold compress 43 has a stepped opening 431 in the middle toward the rear end for the heat shield 45 and the front end of the transparent crystal 44 to fit and embed. The rear end of the cold compress 43 is provided with a mounting boss 432 around the stepped opening 431 for passing through the cold guide plate mounting hole 422 and mounting fitting with the refrigeration bracket 46.

The light-transmitting crystal 44 is located in the light-exiting direction of the hair removal assembly 20 and disposed at the front end of the filter 24, and the outer surface of the light-transmitting crystal 44 is a polished mirror surface, and can also reflect light to form a light-exiting channel leading to the light-exiting port 16. The two sides of the transparent crystal 44 are provided with slots 441 for fixing the transparent crystal 44 to the cooling bracket 46. The front end of the transparent crystal 44 forms a stepped groove 442 corresponding to the stepped opening 431 of the cold compress 43, so that the heat shield 45 can be fitted in the stepped groove 442 and mounted on the cold compress 43. The front end of the transparent crystal 44 passes through the hole 451 in the heat shield 45 and is inserted into the step opening 431, and the heat shield 45 is pressed between the step opening 431 of the cold compress 43 and the step surface of the step groove 442 of the transparent crystal 44 to insulate heat transfer, preventing the heat of the transparent crystal 44 from being conducted to the cold compress 43. Meanwhile, the heat-insulating sheet 45 closes the gap between the cold dressing 43 and the transparent crystal 44, and also plays a role of sealing, preventing foreign matters from entering the inside of the depilating apparatus 100. The front end of the light-transmitting crystal 44 is just plugged into the stepped opening 431 of the cold dressing 43, and the front end face of the light-transmitting crystal 44 in the light-emitting direction and the front end face of the cold dressing 43 form a smooth working face of the epilating apparatus 100 while being in contact with the skin of the user. The transparent crystal 44 can be made of transparent material such as sapphire, ruby, quartz glass, K9 glass, etc.

The refrigeration bracket 46 is provided with a refrigeration piece mounting opening 461 and a transparent crystal mounting opening 462 respectively, the cold compress refrigeration piece 41 is mounted in the refrigeration piece mounting opening 461, and the transparent crystal 44 is mounted in the transparent crystal mounting opening 462.

The refrigerating module 40 is assembled and then the refrigerating bracket 46 is installed at the front end of the housing 10, and the peripheral side of the refrigerating module 40 is closed by the mouthpiece cover 13. The cold face of the cold application fins 41 engages the cold conduction plate 42, transferring the "cold" through the cold conduction plate 42 to the cold application 43. The light-transmitting crystal 44 is a light-emitting portion disposed in the light-emitting port 16, the cold compress 43 surrounds the light-emitting port 16, the heat dissipation assembly 30 dissipates heat for the cold compress cooling plate 41 and the light-transmitting crystal 44, and both the heat generated by the cold compress cooling plate 41 and the heat generated by the light waves passing through the light-transmitting crystal 44 are dissipated to the outside air of the hair removal device 100 through the heat dissipation assembly 30. This maintains the temperature of the transparent crystal 44 at room temperature, and also maintains the "ice" feel of the cold dressing 43, so that the skin-contacting surface of the epilator (the front face of the cold dressing 43 and transparent crystal 44) experiences "cold" in the outer ring and room temperature in the middle, avoiding the burning sensation that would occur when light is applied to the skin.

The heat sink assembly 30 includes a heat conducting assembly 31, an air duct 32 and a fan 33. The heat conducting assembly 31 is connected with the refrigeration assembly 40 and the fan 33, conducts heat of the refrigeration assembly 40 to the fan 33, and radiates the heat through the air duct 32.

The heat of the hot surface of the cold-application cooling plate 41 and the transparent crystal 44 is sequentially conducted to the fan 33 through the heat conducting plate 311, the heat conducting pipe 312, and the heat conducting shell 313. In the illustrated embodiment, the heat conductive plate 311, the heat conductive pipe 312, and the heat conductive shell 313 are integrally welded.

In the illustrated embodiment, the cold-compress cooling sheet 41 and the transparent crystal 44 in thermal conductive connection with the cold compress 43 are simultaneously bonded to the thermal conductive plate 311, i.e., the transparent crystal 44 is directly bonded to the thermal conductive plate 31 to dissipate heat after conducting heat through the thermal conductive plate 31.

In other embodiments, the refrigeration assembly 40 may adopt two or more refrigeration sheets (including a refrigeration sheet 41 and a crystal refrigeration sheet) respectively attached to the refrigeration piece 43 and the transparent crystal 44, each refrigeration sheet is thermally conductively attached to the heat conducting plate 311, wherein the refrigeration sheet 41 is thermally conductively connected to the refrigeration piece 43, the other refrigeration sheets are crystal refrigeration sheets, and the cold surface of the crystal refrigeration sheet is attached to the transparent crystal 44 to cool the transparent crystal 44. That is, the refrigeration component 40 further comprises a crystal refrigeration piece, the light-transmitting crystal 44 is refrigerated and cooled by the crystal refrigeration piece, the crystal refrigeration piece conducts heat through the heat conduction plate 31 and then radiates heat, and the light-transmitting crystal 44 is indirectly attached to the heat conduction plate 311 through the crystal refrigeration piece in a heat conduction manner.

It should be noted that the heat conducting plate 311 may be directly bonded to the cold compress cooling plate 41 and the transparent crystal 44, or the contact area may be increased by coating a heat conducting silicone grease or disposing a heat conducting silicon wafer. In the illustrated embodiment, the contact surfaces between the heat-conducting plate 311 and the cold-application cooling plate 41 and the light-transmitting crystal 44 are coated with heat-conducting silicone grease.

The air duct 32 is formed by buckling a first air duct shell 321 and a second air duct shell 322 to form an air duct inlet 323 and an air duct outlet 324. The air duct air inlet 323 is arranged at the position of the air duct 32 facing the fan 33, so as to introduce the outlet air of the fan 33 into the air duct 32; the air duct outlet 324 is provided toward the air outlet 15 to blow the air of the air duct 32 to the outside of the housing 10. The reflection light-collecting cover 22 of the hair removal assembly 20 is located entirely within the air duct 32 or at the rear end (the end opposite to the light-emitting direction) of the reflection light-collecting cover 22, that is, the air within the air duct 32 flows through the reflection light-collecting cover 22 to take away the heat of the reflection light-collecting cover 22.

Referring to fig. 10 and 11, the blower 33 includes a fan blade 331 and a blower housing 332, the fan blade 331 is rotatably mounted on a fan blade shaft 3321 in the blower housing 332, and a blower inlet 333 and a blower outlet 334 are respectively disposed on a side of the blower housing 332 facing the air inlet 15 and a side facing the air duct inlet 323. The heat conducting shell 313 is fastened on the fan shell 332 from the direction of the fan air inlet 333. The fan housing 332 is provided at both sides thereof with fan bracket passing holes 3322, and the fan bracket 34 passes through the fan bracket passing holes 3322 to be connected to the sealing bracket 35 provided at a side of the heat conductive housing 313 facing the air inlet 15, thereby integrally connecting the sealing bracket 35, the heat conductive member 31 and the fan 33. In the illustrated embodiment, the blower inlet 333 is perpendicular to the blower outlet 334, and the blower 33 may be a volute fan, for example.

The sealing bracket 35 is disposed between the heat conductive shell 313 and the air inlet 15, and the middle of the sealing bracket 351 forms an air inlet channel 351 and fan bracket mounting holes 352 at two sides. The air inlet channel 351 communicates the air inlet 15 and the fan air inlet 333, so that the outside air entering from the air inlet 15 directly enters the fan air inlet 333 through the air inlet channel 351. The fan support mounting holes 352 provide for mounting of the distal end of the fan support 34 through the fan support aperture 3322. When the fan 331 of the fan 33 rotates, wind enters from the air inlet 15 through the sealing bracket 35 and the heat conducting shell 313 from the fan air inlet 333, and blows toward the air duct 32 through the fan air outlet 334. At this time, the air in the air duct 32 flows through the reflection light-gathering cover 22, and finally the heat from the cold compress cooling plate 41 and the light-transmitting crystal 44 of the heat conduction plate 311 and the heat of the reflection light-gathering cover 22 are exhausted outside the depilation instrument 100 through the air duct 32.

Referring to fig. 12 and 13, the heat conducting plate 311 is attached to the hot surface of the cold compressing cooling plate 41 of the cooling assembly 40 and the transparent crystal 44, and conducts the heat of the cooling assembly 40 to the fan 33 through the heat conducting pipe 312 and the heat conducting shell 313. Referring to fig. 14 and fig. 15, the fan 331 of the fan 33 rotates to blow the hot air to the air duct 32; the wind flowing through the wind duct 32 carries the heat of the reflective light-gathering cover 22 in the wind duct 32 to blow toward the wind outlet 15, and finally is discharged out of the depilating apparatus 100.

Referring to fig. 16 and 19, the wind entering the epilating apparatus 100 defines a ventilation duct from the wind inlet 14 to the wind outlet 15 (as shown by arrows in fig. 16, 17, and 18). When the depilating apparatus 100 is in operation, the light generated by the emitter 21 of the depilating assembly 20 is irradiated onto the filter 24, and the filter 24 retains the red light to irradiate towards the light-transmitting crystal 44 at the front end, and irradiates the skin to be depilated from the front end face of the light-transmitting crystal 44.

When the hair removal assembly 20 of the hair removal device 100 is in operation, the cooling assembly 40 is simultaneously operated. The cold face of the cold compress refrigeration sheet 41 of the refrigeration assembly 40 is attached to the cold guide plate 42, the cold guide plate 42 is attached to the cold compress 43, and the cold generated by the cold compress refrigeration sheet 41 is transmitted to the cold compress 43 through the cold guide plate 42, so that the skin surface in contact with the cold compress 43 feels cold. The hot side of the cold compress refrigeration piece 41 is contacted with the heat conduction assembly 31, and the heat is dissipated to the cold compress refrigeration piece 41 through the fan 33 and the air duct 32. Specifically, the hot side of the cold compressing cooling plate 41 contacts the heat conducting plate 311, and conducts the heat of the cold compressing cooling plate 41 to the heat conducting plate 311, and then the heat is conducted to the fan 33 sequentially through the heat conducting pipe 312 and the heat conducting shell 313. The transparent crystal 44 is disposed in the light outlet 16 and contacts the heat conducting element 31, and heat generated by the light wave passing through the transparent crystal 44 is dissipated through the heat conducting element 31, so that the transparent crystal 44 maintains the same temperature as room temperature. Specifically, one side of the transparent crystal 44 contacts the heat conducting plate 311, and conducts the heat of the transparent crystal 44 to the heat conducting plate 311, and then the heat is conducted to the fan 33 through the heat conducting pipe 312 and the heat conducting shell 313 in sequence.

When the depilating apparatus 100 is in operation, external wind is sucked into the fan inlet 333 of the fan 33 from the air inlet 14 of the housing 10 through the opening of the sealing bracket 35 and the opening of the heat conducting shell 313, and is output to the air duct inlet 323 of the air duct 32 from the fan outlet 334 through the operation of the fan blades 331 of the fan 33. At this time, the heat from the cooling module 40 at the fan 33 is converted into hot air into the air duct 32 along with the flow of the wind. The air flowing through the air duct 32 also carries the heat of the reflective light-gathering cover 22 in the air duct 32, and finally is exhausted out of the depilating apparatus 100 through the air duct outlet 324 and the air outlet 15.

When the depilating apparatus 100 is in operation, heat generated by the cold compress refrigerating sheet 41 and heat brought by the light wave passing through the light-transmitting crystal 44 are all exhausted to the air outside the depilating apparatus 100 through the heat dissipation assembly 30, so that the temperature of the light-transmitting crystal 44 can be kept at room temperature, and the 'ice feeling' of the cold compress 43 can also be kept, the cold compress 43 surrounds the front end of the light-transmitting crystal 44 and is in contact with the skin, the outer ring of the skin of the contact part feels 'cold' and the middle feels room temperature, and the use feeling is greatly improved.
