Description

Technical Field

[0001] This utility model relates to a face mask with physiotherapy function and a hair dryer. Background Technology

[0002] Current hair dryer caps are primarily designed for airflow and aesthetics, typically consisting of a front and back cover made of injection-molded plastic. Internally, they only have simple air ducts to guide cool or hot air through the outlet to the hair or scalp. These caps offer only a single airflow function and cannot provide additional therapeutic or conditioning effects. Users can only rely on cool or hot air for drying, which fails to meet the growing demand for multifunctional hair styling and scalp care.

[0003] In addition, with the popularization of health care concepts, the application of technologies such as phototherapy and infrared therapy in the beauty and hair care field has gradually increased. Separate therapy modules (such as phototherapy caps and infrared therapy patches) need to be used separately from hair dryers, which not only increases equipment investment and operation steps, but also makes it difficult to achieve simultaneous blow-drying and therapy, reducing the convenience of use and overall care efficiency. Utility Model Content

[0004] The primary objective of this invention is to provide a face cover with therapeutic functions that integrates a therapeutic light source and a high-efficiency air duct.

[0005] The second objective of this invention is to provide a hair dryer that combines blowing and physiotherapy functions.

[0006] The primary objective of this invention is achieved as follows:

[0007] A face mask with physiotherapy function, the face mask includes a front cover, a lamp panel, an air guide cover and a rear cover, the front cover is provided with a first mounting port and the air guide cover is provided with a second mounting port;

[0008] The rear cover is provided with a spray nozzle, the diameters of the first mounting port and the second mounting port are both larger than the diameter of the spray nozzle, and the rear cover is provided with a second air vent around the spray nozzle;

[0009] The front cover, air guide cover and rear cover are assembled, and the spray nozzle extends out of the first mounting port and the second mounting port in sequence. The gap between the spray nozzle, the first mounting port and the second mounting port forms an annular air outlet.

[0010] An air channel is formed between the surface of the rear cover and the bottom surface of the air guide cover. The inlet of the air channel is connected to the second air outlet, and the outlet of the air channel is connected to the annular air outlet.

[0011] A lamp panel receiving cavity is formed between the surface of the air guide cover and the bottom surface of the front cover. The lamp panel is placed in the lamp panel receiving cavity. The lamp panel is provided with lamp beads with physiotherapy function at intervals. The front cover is provided with a light-transmitting window corresponding to the position of the lamp beads.

[0012] The therapeutic lamp panel and air guide mechanism are organically integrated into the face cover structure. By utilizing the lamp panel receiving cavity and light-transmitting window between the front cover and the air guide cover, it is possible to ensure that the infrared or visible light emitted by the lamp beads is collimated and directly reaches the scalp or hair surface to achieve the phototherapy function, without affecting the airflow channel layout of the hair dryer. This allows for simultaneous blow-drying and therapeutic treatment, enhancing the overall effect of hair care.

[0013] By setting a second air vent around the outer perimeter of the back cover, and sequentially using the annular gap between the first mounting port, the second mounting port, and the spray nozzle to form an annular air outlet, cold or hot air is sprayed out from the annular air outlet, and mist is sprayed out along the spray nozzle. The mist and air are output synchronously, making it easier to adhere to the hair and scalp, thus improving the care effect.

[0014] The air duct between the rear cover and the air guide cover, as well as the lamp plate receiving cavity between the air guide cover and the front cover, are staggered and do not interfere with each other, avoiding direct impact of airflow on the lamp beads or circuits, ensuring the heat dissipation safety of the physiotherapy lamp beads. At the same time, the reasonable airflow guidance design optimizes the wind speed and wind pressure, making it more comfortable to use and with lower noise.

[0015] The primary objective of this utility model can also be achieved by the following technical measures:

[0016] Furthermore, a lens is provided on the bottom wall of the front cover at the position corresponding to the light-transmitting window.

[0017] After a lens is installed on the bottom wall of the front cover corresponding to the light-transmitting window, the light emitted by the lamp can be focused or diffused, so that the phototherapy energy can be applied to the scalp or hair more accurately. The lens can also improve the uniformity of the light spot, reduce light intensity hot spots, and improve the comfort and safety of the physiotherapy effect.

[0018] Furthermore, the inner wall of the air duct is provided with guide vanes for changing the direction of airflow.

[0019] Adding guide vanes to the inner wall of the air duct allows for precise adjustment of the airflow direction and speed, avoiding airflow turbulence or dead zones and ensuring uniform airflow speed at the annular air outlet. At the same time, the guide vanes also reduce wind resistance noise, making the use process quieter and more comfortable.

[0020] Furthermore, both the air guide cover and the rear cover are flared covers.

[0021] Both the air guide cover and the rear cover are horn-shaped structures, which can naturally diffuse and concentrate airflow. Through geometric gradient, the airflow can be smoothly accelerated or decelerated, which can both increase wind speed and reduce eddy generation. The horn-shaped design also increases the internal volume, which is conducive to the layout optimization of the light panel and air guide mechanism.

[0022] Furthermore, the lamp bead is a low-energy laser lamp.

[0023] Using low-energy laser beads as the light source for physiotherapy, it can emit lasers of specific wavelengths to promote scalp blood circulation and cell metabolism; low-energy lasers are highly safe and have controllable penetration depth, enabling deep physiotherapy without increasing the temperature, thus balancing effectiveness and comfort.

[0024] Furthermore, the back of the rear cover is provided with a locking cavity that communicates with the spray nozzle.

[0025] The back cover has a locking cavity that connects to the spray nozzle, which allows the atomizing device module to be quickly inserted and tightly positioned, making the connection between the spray nozzle and the atomizing device more reliable. This locking structure simplifies the assembly process and improves the sealing of the atomizing nozzle, preventing leakage and backflow.

[0026] Furthermore, magnets or metal parts that can be attracted by magnets are provided at intervals on the back side of the rear cover.

[0027] Magnets or magnetically attachable metal parts are placed on the back of the rear cover, allowing for quick magnetic attraction between the cover and the atomizing module or the main body, eliminating the need for screws and making installation and disassembly more convenient.

[0028] The second objective of this utility model is achieved as follows:

[0029] A hair dryer further includes a body, an atomizing device, a fan assembly, and a controller, wherein the body has a built-in mounting base with a mounting cavity, and an air gap is formed between the outer wall of the mounting base and the inner wall of the body;

[0030] The front of the machine body has a first air inlet with a ventilation gap and a metal part with a magnet or a metal part that can be attracted by a magnet, and the back of the machine body has an air inlet.

[0031] The atomizing device is equipped with a locking head, which has a mist outlet. The locking head extends into the locking cavity and locks in place, thereby connecting the atomizing device and the face cover, and simultaneously connecting the mist outlet and the spray nozzle.

[0032] The atomizing device is inserted into the mounting cavity, the face cover sits in front of the body, and the magnet and metal parts are attracted to each other to connect the face cover and the body.

[0033] The fan assembly is housed inside the machine body, and the controller is mounted on the machine body.

[0034] The atomizing device, fan assembly, and lamp panel are electrically connected to the controller, which controls the start and stop of the atomizing device, the lamp panel, and the fan assembly, as well as their speed adjustment.

[0035] This design integrates the atomizing device and face cover into a detachable therapy module, and uses magnets / metal parts at the front of the device to achieve tool-free quick attachment and fixation. Users can easily attach or detach the therapy module, greatly simplifying the installation and cleaning maintenance process and improving the usability and convenience of the product.

[0036] After the fan is turned on, the hair dryer can generate a strong and stable ring of cold or hot air, and can also work in sync with the fine mist or therapeutic light generated by the physiotherapy module. With the controller, the atomizing device, light panel and fan can be independently started, stopped and speed adjusted. Users can switch between multiple modes such as drying hair, mist therapy and light therapy with one click to meet their personalized care needs.

[0037] The second objective of this utility model can also be achieved by the following technical measures:

[0038] Furthermore, the atomizing device includes an atomizing component, a liquid storage bottle, and an electric wire. The atomizing component includes an atomizing plate. The liquid storage bottle has an injection port with a plug at the injection port. The atomizing component is fixed to the liquid storage bottle, and the inlet of the atomizing component is connected to the opening of the liquid storage bottle.

[0039] The atomizing component is provided with a locking head above it, the locking head is provided with a third conductive contact, the locking cavity of the face cover is provided with a fourth conductive contact that is electrically connected to the lamp board, the locking head extends into the locking cavity and locks in place, and the third conductive contact and the fourth conductive contact are in contact.

[0040] The liquid storage bottle is provided with a second conductive contact and a lead groove for easy passage of wires. The wires are placed in the lead grooves, with one end of the wires connected to the second conductive contact and the other end of the wires connected to the atomizing component and the third conductive contact, respectively.

[0041] The atomizing component, liquid reservoir, and wiring are organically integrated into a single module. The atomizing plate is fixed at the mouth of the liquid reservoir, and essential oils or care solutions can be replenished as needed through the filling port and cap. The operation is simple, requires no tools, and the filling process is clean and hygienic, leaving no liquid residue inside or outside the device.

[0042] A second conductive contact and lead wire groove are provided on the side of the liquid storage bottle, so that the wires are laid out along the predetermined channel, which not only ensures the neatness of the line, but also prevents the cable from becoming loose or damaged under vibration or airflow impact.

[0043] The locking head extends into the locking cavity and locks in place, thus assembling the atomizing device and face cover into a physiotherapy module.

[0044] The third and fourth conductive contacts come into contact to supply power to the lamp board.

[0045] Furthermore, the mounting cavity is provided with a first conductive contact that is connected to the controller, and the atomizing device is inserted into the mounting cavity, where the second conductive contact and the first conductive contact make contact.

[0046] A first conductive contact is set inside the mounting cavity. After contacting the second conductive contact on the liquid storage bottle, the circuit with the controller is closed, realizing automatic power supply without additional cables. This design not only reduces the complexity of cable layout, but also enhances the reliability and safety of modular plugging and unplugging.

[0047] The beneficial effects of this utility model are as follows:

[0048] This invention organically integrates the therapeutic lamp plate and the air guide mechanism into the face cover structure. By utilizing the lamp plate receiving cavity and light-transmitting window between the front cover and the air guide cover, it can ensure that the infrared or visible light emitted by the lamp beads is collimated and directly reaches the scalp or hair surface to achieve the phototherapy function, without affecting the airflow channel layout of the hair dryer. This allows for simultaneous blow-drying and therapeutic treatment, improving the overall effect of hair care.

[0049] This invention features a second air vent on the outer periphery of the rear cover, and an annular air outlet formed by sequentially utilizing the annular gap between the first mounting port, the second mounting port, and the spray nozzle. Cold or hot air is ejected from the annular air outlet, and mist is ejected along the spray nozzle. The mist and air are output synchronously, making it easier to adhere to the hair and scalp, thus improving the care effect.

[0050] In this invention, the air passage between the rear cover and the air guide cover, as well as the lamp plate receiving cavity between the air guide cover and the front cover, are staggered and do not interfere with each other, avoiding direct impact of airflow on the lamp beads or circuits, ensuring the heat dissipation safety of the physiotherapy lamp beads. At the same time, the reasonable airflow guidance design optimizes the wind speed and wind pressure, making it more comfortable to use and with lower noise.

[0051] This invention uses low-energy laser beads as a therapeutic light source, which can emit lasers of specific wavelengths to promote scalp blood circulation and cell metabolism. The low-energy laser is highly safe and has a controllable penetration depth, enabling deep therapy without increasing the temperature, thus balancing effectiveness and comfort.

[0066] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0067] Example 1, combined with Figures 1 to 14 As shown, a hair dryer includes a body 1, a face cover 2, an atomizing device 3, a fan assembly and a controller 4. The face cover 2 includes a front cover 21, a light panel 22, an air guide cover 23 and a rear cover 24. The front cover 21 is provided with a first mounting port 211 and the air guide cover 23 is provided with a second mounting port 212.

[0068] The rear cover 24 is provided with a spray nozzle 241. The diameters of the first mounting port 211 and the second mounting port 212 are both larger than the diameter of the spray nozzle 241. The rear cover 24 is provided with a second air vent 242 around the spray nozzle 241.

[0069] The front cover 21, the air guide cover 23 and the rear cover 24 are assembled. The spray nozzle 241 extends out of the first mounting port 211 and the second mounting port 212 in sequence. The gap between the spray nozzle 241, the first mounting port 211 and the second mounting port 212 forms an annular air outlet 25.

[0070] An air passage 26 is formed between the surface of the rear cover 24 and the bottom surface of the air guide cover 23. The inlet of the air passage 26 is connected to the second air outlet 242, and the outlet of the air passage 26 is connected to the annular air outlet 25.

[0071] A lamp plate receiving cavity 27 is formed between the surface of the air guide cover 23 and the bottom surface of the front cover 21. The lamp plate 22 is placed in the lamp plate receiving cavity 27. The lamp plate 22 is provided with lamp beads 221 with physiotherapy function at intervals. The front cover 21 is provided with a light-transmitting window corresponding to the position of the lamp beads 221.

[0072] Furthermore, a lens is provided on the bottom wall of the front cover 21 at the position corresponding to the light-transmitting window.

[0073] Furthermore, the inner wall of the air duct 26 is provided with a guide plate 261 for changing the direction of airflow.

[0074] Furthermore, the lamp bead 221 is a low-energy laser lamp.

[0075] Furthermore, the back cover 24 is provided with a retaining cavity 243 communicating with the spray nozzle 241, and the retaining cavity 243 is provided with a fourth conductive contact electrically connected to the lamp panel 22.

[0076] Furthermore, the back cover 24 is provided with metal parts that can be attracted by a magnet at intervals on its back side.

[0077] The atomizing device 3 includes an atomizing component 31 and a liquid storage bottle 32. The atomizing component 31 includes an atomizing plate 311. The atomizing component 31 is fixed on the liquid storage bottle 32. The liquid inlet of the atomizing component 31 is connected to the bottle opening of the liquid storage bottle 32. The atomizing component 31 is also provided with a locking head 312.

[0078] Furthermore, it also includes an electrical wire. The liquid storage bottle 32 is provided with a second conductive contact and a lead wire groove 321 for easy passage of the electrical wire. The electrical wire is placed in the lead wire groove 321, with one end of the electrical wire connected to the second conductive contact and the other end of the electrical wire connected to the atomizing component 31.

[0079] Furthermore, the liquid storage bottle 32 has an injection port, and a plug is provided at the injection port.

[0080] Furthermore, the card holder 312 has a mist outlet and a third conductive contact.

[0081] The body 1 includes a hollow outer shell 12 and a hollow handle 13. The hollow handle 13 and the hollow outer shell 12 are connected. The hollow outer shell 12 has a mounting base 14 with a mounting cavity 141 inside. The mounting cavity 141 is provided with a first conductive contact connected to the controller 4. An air gap 16 is formed between the outer wall of the mounting base 14 and the inner wall of the hollow outer shell 12. The front of the hollow outer shell 12 is spaced apart with a first air vent 121 connecting the air gap 16 and magnets are spaced apart. The back of the hollow outer shell 12 is spaced apart with an air inlet 15.

[0082] The fan assembly is housed inside the hollow handle 13, and the controller 4 is mounted on the hollow handle 13 and connected to an external power source.

[0083] Furthermore, it also includes a heating device, which is installed inside the body 1. The heating device is electrically connected to the controller 4, and the controller 4 controls the start and stop of the heating device.

[0084] Furthermore, the lamp beads are low-energy laser lamps and / or near-infrared lamps and / or blue lamps.

[0085] The locking head 312 of the atomizing device 3 is inserted into the locking cavity 243 on the back of the rear cover 24 of the face cover 2, and mechanical locking is achieved through the locking head 312 component;

[0086] When locked, the third conductive contact on the atomizing device 3 reliably contacts the fourth conductive contact inside the rear cover 24, establishing an electrical path.

[0087] After assembly, the atomizing device 3 and the face cover 2 are connected as one unit, forming a detachable physiotherapy module.

[0088] The above-mentioned physiotherapy module is placed at the front end of the hollow outer shell 12 of the body 1;

[0089] The nebulizer 3 of the physiotherapy module is inserted into the mounting cavity 141, and the second conductive contact is connected with the first conductive contact in the mounting cavity 141. At the same time, the metal parts on the outside of the face cover 2 and the magnet on the inside of the outer shell of the body 1 are attracted to achieve stable positioning.

[0090] At the same time, the second air vent 242 on the faceplate 2 is precisely aligned with the first air vent 121 on the body 1 to ensure that the airflow channel is connected;

[0091] In the circuit, the first conductive contact, the second conductive contact, the third conductive contact, and the fourth conductive contact are connected to the controller 4 in sequence, so that the lamp panel 22, the atomizing device 3, and the fan assembly are all under the unified management of the controller 4.

[0092] The controller 4 starts the fan assembly, and outside air is drawn in through the air inlet 15 on the back of the body 1. The air flows along the hollow shell 12 and the air gap 16, and enters the annular air channel 26 built into the face cover 2 through the first air inlet 121 and the second air inlet 242. Finally, it is discharged at high speed through the annular air outlet 25, forming an annular airflow.

[0093] During this process, the user can start the heating device through the controller 4. The heat generated by the heating device heats the air to form hot air, which is discharged at high speed through the annular air outlet 25, forming an annular hot air flow.

[0094] When the controller 4 simultaneously activates the atomizing device 3, the essential oil is dispersed into micron-level fine mist under the action of the atomizing plate 311;

[0095] Fine mist is sprayed from the spray nozzle 241 and located in the center of the annular air outlet 25;

[0096] At the same time, the circular wind envelops the droplets and pushes them forward, allowing the droplets and wind to act synchronously on the hair and scalp, achieving a seamless combination of drying and conditioning.

[0097] The annular air outlet 25 forms a "wind wall" structure around the spray nozzle 241, which creates a high-pressure barrier around the main airflow. The mist is sprayed straight forward from the spray nozzle 241 and cannot pass through the annular hot air barrier to spread to the surroundings. This structure can concentrate the output of mist droplets and prevent the mist from flowing back or splashing outward, ensuring the cleanliness of the exterior of the machine body 1 and the usage environment.

[0098] First, remove the physiotherapy module (face cover 2 + nebulizer 3) from the body 1, unscrew the filler cap on the liquid storage bottle 32 counterclockwise, and remove the cap.

[0099] Slowly inject the prepared essential oil or hair conditioner into the storage bottle 32 through the injection port until the liquid level reaches the maximum safe level marked on the bottle. Avoid injecting too much at once to prevent overflow or backflow due to excessive liquid level during use.

[0100] After filling, tighten the plug clockwise to ensure a tight seal between the plug and the filling port, eliminating any risk of leakage.

[0101] Insert the pre-filled physiotherapy module back into the body 1. After hearing a "click" sound, confirm that the magnetic part is firmly attached to the metal part and that the first air vent 121 and the second air vent 242 are aligned. Then you can resume normal use.

[0102] Example 2, the difference between Example 2 and Example 1 is:

[0103] The atomizing device 3 includes an atomizing component 31 and a liquid storage bottle 32. The atomizing component 31 includes an atomizing plate 311 and is provided with a second conductive contact. The atomizing component 31 is detachably mounted on the liquid storage bottle 32 (e.g., magnetically attached or snapped). The liquid inlet of the atomizing component 31 is connected to the bottle opening of the liquid storage bottle 32.

[0104] The atomizing component 31 is provided with a locking head 312, which has a mist outlet and a third conductive contact. The third conductive contact and the second conductive contact are electrically connected.

[0105] The locking head 312 of the atomizing device 3 is inserted into the locking cavity 243 on the back of the rear cover 24 of the face cover 2, and mechanical locking is achieved through the locking head 312 component;

[0106] When locked, the third conductive contact on the atomizing device 3 reliably contacts the fourth conductive contact inside the rear cover 24, establishing an electrical path.

[0107] After assembly, the atomizing device 3 and the face cover 2 are connected as one unit, forming a detachable physiotherapy module.

[0108] The above-mentioned physiotherapy module is placed at the front end of the hollow outer shell 12 of the body 1;

[0109] The nebulizer 3 of the physiotherapy module is inserted into the mounting cavity 141, and the second conductive contact is connected with the first conductive contact in the mounting cavity 141. At the same time, the metal parts on the outside of the face cover 2 and the magnet on the inside of the outer shell of the body 1 are attracted to achieve stable positioning.

[0110] At the same time, the second air vent 242 on the faceplate 2 is precisely aligned with the first air vent 121 on the body 1 to ensure that the airflow channel is connected;

[0111] In the circuit, the first conductive contact, the second conductive contact, the third conductive contact, and the fourth conductive contact are connected to the controller 4 in sequence, so that the lamp panel 22, the atomizing device 3, and the fan assembly are all under the unified management of the controller 4.

[0112] In Example 2, the liquid storage bottle 32 can be disassembled and replaced independently. Users can quickly replace the liquid storage bottle 32 to replenish or replace the essential oil or care solution, which greatly simplifies the maintenance process and improves the convenience of daily use.

[0113] When the atomizing component 31 and the liquid storage bottle 32 are inserted into the mounting cavity 141 of the body 1, the second conductive contact located on the side wall of the liquid storage bottle 32 can automatically connect to the first conductive contact in the mounting cavity 141, instantly completing the electrical power supply without the need to manually plug or unplug any wires. The operation is intuitive and reliable.
