Description

Technical Field

[0001] This utility model relates to atomizing therapy module and a hair dryer. Background Technology

[0002] Currently, the majority of hair dryers on the market have a nozzle (or air outlet) structure primarily focused on airflow guidance and aesthetics. Their internal components typically consist of only one or more simple air ducts to direct the airflow generated by the fan assembly to the hair or scalp for drying. These nozzles lack structural integration with other therapeutic or conditioning functions, often relying solely on hot or cold air, failing to meet modern consumers' demands for multi-functional health care products.

[0003] Meanwhile, phototherapy and beauty sprays (such as essential oil atomization) are becoming increasingly popular in the beauty and health fields. However, the phototherapy caps and essential oil atomizers are mostly standalone devices that need to be operated separately from hair dryers. This not only increases equipment investment and usage steps, but also makes it impossible to simultaneously achieve drying, phototherapy, and essential oil care, resulting in an inconsistent user experience and low care efficiency. Utility Model Content

[0004] The primary objective of this invention is to provide a nebulizer therapy module that integrates three functions: blowing air, phototherapy, and essential oil spraying.

[0005] The second objective of this invention is to provide a hair dryer that can perform blow-drying, light therapy, and essential oil spraying.

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

[0007] A nebulization therapy module includes a face cover and a nebulizing device. A spray nozzle is provided on the front of the face cover, and an annular air outlet is provided on the front of the face cover around the spray nozzle. A second air outlet is provided on the back of the face cover. An air channel is built into the face 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.

[0008] The atomizing device is detachably mounted on the face cover, and the mist outlet of the atomizing device is connected to the spray nozzle.

[0009] The atomizing therapy module organically integrates the face cover with the atomizing device. While the hair dryer outputs ring-shaped cold air and ring-shaped hot air, it can atomize essential oils or conditioning solutions into micron-sized droplets and precisely spray them out along the central spray nozzle, achieving simultaneous drying and conditioning. This not only improves conditioning efficiency but also saves users time costs associated with secondary operations.

[0010] The annular air outlet is located around the spray nozzle. The stable airflow formed by the air channel surrounds the spray nozzle, which can create a negative pressure zone in the center. This actively adsorbs and encapsulates the droplets, enhances the fusion of the droplets and hot air, and allows the care ingredients to adhere more evenly to the hair and scalp, significantly improving the utilization rate of the atomized liquid and the care effect.

[0011] The back of the faceplate features a second air vent with an internal air channel, ensuring unobstructed airflow. The ring-shaped air outlet surrounding the spray nozzle creates a stable negative pressure zone, making it easier for the atomized micro-droplets to be carried by the main airflow and concentratedly sprayed onto the hair and scalp surface. This significantly improves the utilization rate and adhesion efficiency of the atomized liquid, ensuring that the care ingredients can penetrate evenly into the hair or scalp, enhancing the care effect.

[0012] The "wind wall" isolation structure formed between the negative pressure zone and the annular air outlet can effectively block the fog from spreading outward or flowing back, avoiding spray splashing or contaminating the outside of the machine.

[0013] The primary objective of this utility model can also be achieved by the following technical measures:

[0014] Furthermore, the back of the face cover is provided with a locking cavity that communicates with the spray nozzle, the atomizing device is provided with a locking head, the locking head has the mist outlet, the locking head is inserted into the locking cavity and locked, so as to connect the atomizing device and the face cover, and at the same time the mist outlet and the spray nozzle are connected.

[0015] The locking cavity on the back of the faceplate works in conjunction with the locking head of the atomizing device, allowing for simple and quick modular connection without the need for screws or additional clamps, greatly improving the ease of assembly and disassembly.

[0016] After the locking head is inserted into the locking cavity and locked, it ensures precise alignment between the mist outlet and the spray nozzle on the faceplate, avoiding leakage or deflection caused by installation errors and improving the stability and consistency of the atomization effect.

[0017] Furthermore, the atomizing device includes an atomizing component and a liquid storage bottle. The atomizing component includes an atomizing plate and is fixed to the liquid storage bottle. The liquid inlet of the atomizing component is connected to the bottle opening of the liquid storage bottle, and the atomizing component is provided with the locking head.

[0018] The atomizing component is integrated and fixed with the liquid storage bottle, making the liquid delivery path shorter and more direct, reducing the risk of pipeline blockage and residue, and ensuring uniform and sufficient atomization output each time.

[0019] The compact component structure reduces assembly complexity and enhances the mechanical strength and sealing of the entire nebulizer module, thereby improving its service life and reliability.

[0020] Furthermore, it also includes an electrical wire. The liquid storage bottle is provided with a second conductive contact and a lead groove for easy passage of the electrical wire. The electrical wire is placed in the lead groove, with one end of the wire connected to the second conductive contact and the other end of the wire connected to the atomizing component.

[0021] The second conductive contact on the side wall of the liquid storage bottle, in conjunction with the lead wire groove, enables the orderly routing and secure fixing of the wires, avoiding the possibility of loosening, wear, or interference with the airflow channel.

[0022] One end of the wire is securely connected to the second conductive contact, and the other end is directly connected to the atomizing component, making the electrical connection simple and reliable.

[0023] Furthermore, the atomizing device includes an atomizing component and a liquid storage bottle. The atomizing component includes an atomizing plate and is provided with a second conductive contact. The atomizing component is detachably mounted on the liquid storage bottle. The liquid inlet of the atomizing component is connected to the bottle opening of the liquid storage bottle. The atomizing component is provided with the locking head.

[0024] The second conductive contact is integrated into the atomizing component and is detachably mounted on the reservoir, allowing for quick replacement of the reservoir without disassembling the entire module. Users can replenish essential oils by replacing the reservoir.

[0025] Furthermore, the liquid storage bottle has an injection port, and a plug is provided at the injection port.

[0026] The storage bottle is equipped with a filling port and a removable cap, allowing users to easily add or replace the care solution. The operation is intuitive and quick.

[0027] The cap has excellent sealing performance, which can effectively prevent liquid leakage during use and transportation, prevent external impurities from entering, and keep the care solution clean and stable.

[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. The body has a built-in mounting base with a mounting cavity. An air gap is formed between the outer wall of the mounting base and the inner wall of the body. A first air inlet connected to the air gap is spaced apart at the front of the body, and an air inlet is spaced apart at the back of the body.

[0030] The fan assembly is housed inside the machine body, and the controller is mounted on the machine body.

[0031] The mounting cavity contains a first conductive contact that is electrically connected to the controller.

[0032] The atomizing device is connected to the face cover. The atomizing device is inserted into the mounting cavity. The face cover sits in front of the body, realizing a detachable connection between the face cover, the atomizing device, and the body. At the same time, the first conductive contact and the second conductive contact are in contact, realizing an electrical connection between the atomizing device and the controller. The controller controls the start and stop of the atomizing device.

[0033] The fan assembly and the controller are electrically connected, and the controller controls the start, stop and speed adjustment of the fan assembly.

[0034] The main body, faceplate, and atomizing device are detachably connected via snap-fit ​​and magnetic attachment, allowing users to quickly replace or upgrade components and making maintenance more convenient.

[0035] The layout of the first air inlet and the air gap in the body ensures that the airflow generated by the fan is stably introduced into the air channel of the faceplate, working in conjunction with the atomizing device to achieve precise and synchronous output of air and atomized droplets.

[0036] After the first conductive contact comes into contact with the second conductive contact, the power supply to the atomizing device is automatically completed, eliminating the need for exposed wires or manual plugging and unplugging, thus achieving a simple and safe electrical connection.

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

[0038] It also includes a heating device, which is installed inside the machine body and is electrically connected to a controller, which controls the start and stop of the heating device.

[0039] The device integrates a heating element and is managed by a controller, providing multiple blowing modes such as cool air, warm air, and hot air to meet the needs of different hair types and seasons.

[0040] The controller's combined regulation of the fan, atomizing device, and heating device allows users to switch between treatment modes with a single click, achieving a multi-functional integration of hair drying, mist therapy, light therapy, and heat therapy, thereby enhancing product value and user experience.

[0041] The beneficial effects of this utility model are as follows:

[0042] This invention integrates a face cover with an atomizing device into a misting therapy module. While the hair dryer outputs ring-shaped cold and hot air, it can atomize essential oils or conditioning solutions into micron-sized droplets and precisely spray them out along the central spray nozzle, achieving simultaneous hair drying and conditioning. This not only improves conditioning efficiency but also saves users time costs associated with secondary operations.

[0043] In this invention, the annular air outlet is located around the spray nozzle. The stable airflow formed by the air channel surrounds the spray nozzle, creating a negative pressure zone in the center. This actively adsorbs and encapsulates the droplets, enhancing the fusion of the droplets and hot air. This allows the care ingredients to adhere more evenly to the hair and scalp, significantly improving the utilization rate and care effect of the atomized liquid.

[0044] This invention features a second air vent and an internal air channel on the back of the faceplate, ensuring unobstructed airflow.

This significantly improves the utilization rate and adhesion efficiency of the atomized liquid, ensuring that the care ingredients can penetrate evenly into the hair or scalp, enhancing the care effect.

[0045] The "wind wall" isolation structure formed between the negative pressure zone and the annular air outlet in this invention can effectively block the fog from spreading outward or flowing back, thus preventing spray from splashing or contaminating the exterior of the machine.

[0060] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

The front cover 21 is provided with a light-transmitting window corresponding to the position of the lamp beads 221.

[0066] Furthermore, a lens is provided on the bottom wall of the front cover 21 at the position corresponding to the light-transmitting window.

[0067] Furthermore, the inner wall of the air duct 26 is provided with a guide plate 261 for changing the direction of airflow.

[0069] 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.

[0070] Furthermore, the back cover 24 is provided with metal parts that can be attracted by a magnet at intervals on its back side.

[0071] 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.

[0072] 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.

[0073] Furthermore, the liquid storage bottle 32 has an injection port, and a plug is provided at the injection port.

[0074] Furthermore, the card holder 312 has a mist outlet and a third conductive contact.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] The atomizing device 3 and the face cover 2 are assembled into an atomizing therapy module:

[0079] 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;

[0080] 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.

[0081] After assembly, the atomizing device 3 and the face cover 2 are connected as one unit, forming a detachable atomizing therapy module.

[0082] Assembly of the nebulizer therapy module and body 1:

[0083] The above-mentioned nebulization therapy module is placed at the front end of the hollow outer shell 12 of the body 1;

[0084] The atomizing device 3 of the atomizing therapy module is inserted into the mounting cavity 141. 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.

[0085] 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;

[0086] 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.

[0087] Blower principle:

[0088] 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.

[0089] 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.

[0090] Blow-drying and care can be done simultaneously:

[0091] 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;

[0092] Fine mist is sprayed from the spray nozzle 241 and located in the center of the annular air outlet 25;

[0093] 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.

[0094] Principle of preventing fogging and splashing:

[0095] 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.

[0096] Essential oil filling method:

[0097] First, remove the nebulization therapy 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.

[0098] 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.

[0099] After filling, tighten the plug clockwise to ensure a tight seal between the plug and the filling port, eliminating any risk of leakage.

[0100] Insert the already filled atomizing therapy 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.

[0101] Example 2, the difference between Example 2 and Example 1 is:

[0102] 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.

[0103] 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.

[0104] The atomizing device 3 and the face cover 2 are assembled into an atomizing therapy module:

[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 atomizing therapy module.

[0108] Assembly of the nebulizer therapy module and body 1:

[0109] The above-mentioned nebulization therapy module is placed at the front end of the hollow outer shell 12 of the body 1;

[0110] The atomizing device 3 of the atomizing therapy module is inserted into the mounting cavity 141. 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.

[0111] 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;

[0112] 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.

[0113] 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.

[0114] 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.
