Technical Field

[0001] This invention relates to the field of nursing equipment technology, and in particular to a nursing equipment. Background Technology

[0002] Currently, the working principle of a hair dryer is that an electric motor drives a rotor to rotate the fan blades. When the fan blades rotate, air enters from the air inlet, and the resulting centrifugal airflow is blown out from the air outlet. The heating wire inside the hair dryer is heated by electricity, and the air blown out after passing through the heating wire is warm air. If the heating wire is not activated, the air blown out is cold air.

[0003] In related technologies, the signals of high-power components and control components in vertical hair dryers are prone to mutual interference, resulting in poor overall operational stability of the equipment. Therefore, a solution is urgently needed to address these issues. Summary of the Invention

[0012] In some examples of the present invention, the first housing has a wiring channel, the inlet and outlet ends of which are connected to the air duct. The inlet end is located below the fan and the outlet end is located above the fan. The main unit also includes a power cord, one end of which is connected to the power board and the other end of which is connected to the control board.

[0019] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0020] The following is for reference. Figures 1-7 The nursing device 100 according to an embodiment of the present invention can achieve the effect of separation and hierarchical adaptation of control signals, drive signals and power supply signals based on the difference of circuit signal types, thereby effectively reducing signal crosstalk and power supply interference; it can also better adapt to the curved contour of the user's nursing area through the arc contour of the main unit 20.

[0021] Combination Figures 1-7 As shown, the nursing appliance 100 according to a first aspect embodiment of the present invention includes a base 10 and a main unit 20. The base 10 provides stable support for the main unit 20, preventing it from shaking or tipping over during use and ensuring its stability. The main unit 20 is primarily used to achieve functional output effects (such as blow-drying, styling, and nursing). For example, the nursing appliance 100 can be a vertical hair dryer 22.

[0022] Specifically, the base 10 includes a power board 11, and the main unit 20 is arc-shaped along its length. The main unit 20 includes a housing 21, a fan 22, a fan plate 23, and a control board 24. The housing 21 is disposed on the base 10 and has an air duct 211. The fan 22, the fan plate 23, and the control board 24 are all disposed in the air duct 211, and the fan 22, the fan plate 23, and the control board 24 are distributed at intervals along the length of the housing 21. The fan plate 23 is electrically connected to the control board 24 and the fan 22, respectively. The control board 24 and the fan 22 are both electrically connected to the power board 11.

[0023] Specifically, the power board 11 is adapted to convert external power into voltage and current forms suitable for the internal components of the device, while realizing functions such as voltage stabilization and filtering, safety protection, and power distribution, ensuring stable, safe, and orderly power supply operation for each module of the device; the main unit 20 is arc-shaped in its length direction (such as the overall outline of the main unit 20 being roughly "C" or "U" shaped), which allows the main unit 20 to form an arc-shaped outline. This arc-shaped space can better adapt to the curved outline of the user's head, thereby allowing the main unit 20 to form an effect that surrounds the user's care area (that is, allowing the effective range of the main unit 20 to precisely fit the curve of the user's head), avoiding the local gap problem caused by a single straight surface, and thus allowing the effective range of the main unit 20 to more evenly and comprehensively cover and wrap the curved care area, effectively improving the uniformity and stability of the care treatment.

[0024] In addition, the arc-shaped design of the main unit 20 can reduce the local pressure sensation from the main unit 20 when the user uses the nursing instrument 100, thereby improving the user's comfort during the nursing process and enhancing the user experience.

[0025] Furthermore, the casing 21 of the main unit 20 is provided with an air inlet 293 and an air outlet 2121, and the air duct 211 is connected between the air inlet 293 and the air outlet 2121. This is conducive to forming a continuous airflow circulation effect. In addition, combined with the arc shape of the main unit 20, this is conducive to the air blown from the air outlet 2121 being blown more evenly and comprehensively to the user's styling parts (such as the curved contour of the head), thereby effectively ensuring the consistency of the styling and improving the styling effect.

[0026] Furthermore, the fan 22, fan plate 23, and control plate 24 are all housed within the air duct 211 of the casing 21. This arrangement serves two purposes: firstly, the casing 21 provides structural protection for all three components; secondly, it facilitates heat dissipation of the heat-generating components of the fan plate 23 and control plate 24 through the airflow within the air duct 211, reducing operating temperature rise and ensuring operational stability. The fan 22, fan plate 23, and control plate 24 are spaced apart along the length of the casing 21, preventing localized dense stacking of these components within the air duct 211 and thus ensuring smooth airflow within the air duct 211. Furthermore, the physical separation between the three components reduces the impact of electromagnetic interference generated during the operation of the fan 22 on the electronic components on the control plate 24, ensuring the accuracy of control signal transmission and command execution.

[0027] The fan board 23 is connected to the control board 24 and the fan 22 via electrical signals. Specifically, the control board 24 and the fan board 23 are connected via control signals, and the fan board 23 is connected to the fan 22 via drive signals. The control board 24 and the fan board 23 transmit control signals. The control board 24 can output precise start / stop, speed adjustment, and other command signals to the fan board 23. The fan board 23 decodes and amplifies the control signals and then adapts them to the drive signal requirements of the fan 22, transmitting the drive signals to the fan 22. This provides the matching drive current and signal for the operation of the fan 22, ensuring that the fan 22 operates stably and accurately according to the control commands, and avoiding the problems of excessive signal load and command execution distortion caused by the control board 24 directly driving the fan 22.

[0028] In addition, since the control board 24 (which is a low-power control circuit with high requirements for power supply stability) and the fan 22 (which is a high-power actuator with large current fluctuations during operation) are circuit modules with different power consumption and different power supply requirements, the power supply board 11 is connected to the control board 24 and the fan 22 separately for power supply signals. This allows the control board 24 and the fan 22 to have independent power supply circuits, enabling differentiated power supply for their different power supply requirements. This avoids voltage fluctuations and current crosstalk caused by the two sharing a power supply, and prevents the large current interference of the fan 22 from affecting the signal processing and command output of the control board 24. At the same time, the power supply board 11 can centrally manage the two power supplies and achieve unified protection against overvoltage and overload.

[0029] In summary, the circuit connection method in this case allows for the separation and hierarchical adaptation of control signals, drive signals, and power supply signals based on differences in signal types. This effectively reduces signal crosstalk and power supply interference, ensuring the overall stability and reliability of the circuit. Furthermore, this connection method, which separates signal and power supply links and allocates power independently as needed, ensures clear division of labor and prevents interference between circuit links. It also facilitates independent inspection and replacement of control, power supply, and execution circuit modules, improving the convenience of later maintenance.

[0030] Therefore, by setting up this nursing device 100, the control signal, drive signal, and power supply signal can be separated and hierarchically adapted based on the differences in circuit signal types, thereby effectively reducing signal crosstalk and power supply interference, and ensuring the operational stability and reliability of the overall circuit link; it can also better adapt to the curved contour of the user's nursing area through the arc contour of the main unit 20, thereby improving the shape and nursing effect.

[0031] According to some optional embodiments of the present invention, in combination Figure 1 , Figure 2 , Figure 5 and Figure 7As shown, the housing 21 includes a first housing 212 and a second housing 213. The first housing 212 has an air duct 211. The second housing 213 is located below the first housing 212, and the second housing 213 and the first housing 212 are in a circular arc shape with the same center in the length direction of the main unit 20. The second housing 213 is located on the base 10.

[0032] Specifically, the first housing 212 and the second housing 213 are connected sequentially along the length of the main unit 20. The second housing 213 is connected to the base 10, thus connecting the housing 212 and the base 10 into a whole. This helps to ensure the stability of the main unit 20's placement position and prevents the main unit 20 from shaking or tipping over during operation, thereby ensuring the stability of the nursing device 100 in use. Furthermore, the first housing 212 is provided with an air duct 211. With the directional constraint of the air duct 211, the airflow generated by the fan 22 during operation can flow orderly along the preset path (i.e., the air duct 211), avoiding airflow diffusion, backflow, or turbulence. This improves the smoothness and guidance of the airflow within the air duct 211, thereby effectively improving the working efficiency of the fan 22.

[0033] The first housing 212 and the second housing 213 are arranged from high to low. The second housing 213 is mainly used to establish a connection with the base 10 and can also increase the length of the main unit 20. The first housing 212 is used to form a segmented connection with the first housing 212 and further increase the length of the main unit 20 so that the height of the main unit 20 is more suitable for the nursing position of the user in normal posture (such as sitting or bending over), thus improving the design rationality of the nursing device 100. In addition, the connection method formed by the combination of the first housing 212 and the second housing 213 also makes it easy to disassemble and replace a single housing 21 without replacing the entire housing 21, thereby effectively reducing the later maintenance cost.

[0034] Preferably, the first housing 212 has an air outlet 2121, the second housing 213 has an air inlet 293, and the air duct 211 connects the air inlet 293 and the air outlet 2121. External airflow can enter the air duct 211 through the air inlet 293 on the second housing 213 and be delivered to the air outlet 2121 on the upper first housing 212. This avoids the air inlet 293 and the air outlet 2121 being too far apart, thereby reducing airflow loss. On the other hand, it also avoids the air inlet 293 and the air outlet 2121 being too close, causing the two airflows to interfere with each other, thereby ensuring shaping efficiency. Moreover, the air outlet 2121 is located on the highest part of the first housing 212, which matches the care position under the user's normal posture, avoiding the risk of the air outlet 2121 being too high or too low, thereby ensuring the design rationality of the main unit 20.

[0035] Furthermore, the first housing 212 and the second housing 213 adopt a circular arc design with the same center along the length of the main unit 20. This allows the two segmented housings to form a continuous and smooth circular arc layout with the same center, which is conducive to enclosing a regular inner space. This makes the shape of the main unit 20 more suitable for the curved contour of the human body care parts (such as the head), thereby improving the fit and wrapping of the care parts or hair, and effectively improving the user experience.

[0036] In addition, since the first housing 212 and the second housing 213 adopt a circular arc design with the same center in the length direction of the main body 20, it is beneficial to plan the processing path according to a unified center reference to improve the continuity and standardization of the arc contour of the housing 21. While improving processing efficiency, it is easier to control the curvature consistency of each main body and reduce processing errors. It also allows the curvature of each housing connection surface to be accurately matched. During assembly, it can be quickly positioned based on the center reference, reducing the adjustment and calibration procedures during assembly and improving assembly efficiency.

[0037] Alternatively, the control board 24 is located above the fan 22, that is, downstream of the fan 22 in the airflow direction within the air duct 211. This allows the air blown by the fan 22 to dissipate heat from the control board 24 and its related electronic components, preventing the control board 24 from overheating during long-term operation and ensuring its reliability and stability. The fan board 23 is located between the control board 24 and the fan 22. This allows the fan board 23 to transmit the signals from the control board 24 to the fan 22 more quickly, reducing the signal transmission distance and improving the sensitivity and timeliness of control during the adjustment of the fan 22. Furthermore, the airflow in the air duct 211 can also provide natural cooling for the fan board 23, preventing it from overheating during long-term operation and ensuring the stable transmission of electrical control commands, thereby ensuring the operational stability and reliability of the nursing device 100.

[0038] Specifically, in combination Figures 1-7 As shown, the host 20 also includes a rotating device 25, which is disposed between the first housing 212 and the second housing 213 to drive the first housing 212 to rotate relative to the second housing 213. The power board 11 and the control board 24 are both connected to the rotating device 25.

[0039] It is understandable that the rotating device 25 is positioned between the first housing 212 and the second housing 213. This allows the rotating device 25 to serve as a transmission connection between the first housing 212 and the second housing 213. When the first housing 212 and the second housing 213 rotate relative to each other, the rotating device 25 can provide stable power output and transmission support, eliminating the need for manual adjustment by the user and freeing up the user's hands. It also ensures smoothness during rotation and accuracy of the adjustment angle. The rotating device 25 directly drives the second housing 213 to rotate relative to the first housing 212. This facilitates the automatic adjustment of the position of the air outlet 2121 of the nursing device 100 on a plane perpendicular to the height of the main unit 20, eliminating the need for the user to manually rotate and adjust the position of the air outlet 2121, thereby improving the convenience of the nursing device 100 and enhancing the user experience.

[0040] In addition, the control board 24 and the rotating device 25 transmit control signals. The control board 24 can send control commands (such as rotation direction, rotation angle, etc.) to the rotating device 25, thus ensuring the fast response speed of the rotating device 25 to the control commands. The power board 11 and the rotating device 25 are connected by power signals. The power board 11 can supply power according to the power demand of the rotating device 25, providing a stable working power supply for the rotating device 25 and avoiding drive abnormalities caused by unstable power supply. Furthermore, this arrangement can also facilitate the physical partitioning of the power supply high-voltage circuit and the control low-voltage circuit, thereby avoiding EMI interference caused by cross wiring of the control low-voltage circuit and the power supply high-voltage circuit, and ensuring operational stability.

[0041] Optionally, one of the first housing 212 and the second housing 213 has an air inlet 293, and the first housing 212 has an air outlet 2121 located at the top of the first housing 212. Alternatively, the air inlet 293 can be located at the bottom of the first housing 212. In this case, the air inlet 293 is located at the end of the first housing 212 furthest from the air outlet 2121. This avoids the air inlet 293 and the air outlet 2121 being too close, and prevents the airflow at the two vents from interfering with each other. This mitigates the risk of interference, thus ensuring effective airflow. On the other hand, it prevents the formation of local vortex effects (i.e., the air blown out of the air outlet 2121 quickly flows back to the air inlet 293), thereby ensuring the rationality of the position of the air inlet 293. For example, the air inlet 293 can be located at the top of the second housing 213, so that only a sealing setting is needed at the connection between the first housing 212 and the second housing 213. Even if the first housing 212 rotates relative to the second housing 213, it will not interfere with the airflow effect in the air duct 211.

[0042] Specifically, in combination Figures 1-3As shown, the rotating device 25 includes a rotating motor 251 and a rotating base 253. The rotating motor 251 has an output shaft 252. The rotating motor 251 is disposed in one of the first housing 212 and the second housing 213. The rotating base 253 is disposed on the output shaft 252 and is disposed in the other of the first housing 212 and the second housing 213.

[0043] It is understandable that the rotary motor 251 and the rotating base 253 constitute the main structure of the rotating device 25. The rotary motor 251 is equipped with an output shaft 252. The rotary motor 251 and the rotating base 253 form a transmission relationship through the output shaft 252. The output shaft 252 can stably and continuously transmit power to the rotating base 253, thereby ensuring the directness and stability of power transmission and avoiding jamming during the rotation of the rotating device 25. The rotary motor 251 is set in the first housing 212 and the rotating base 253 is set in the second housing 213, or the rotary motor 251 is set in the second housing 213 and the rotating base 253 is set in the first housing 212. The rotating base 253 and the output shaft 252 are connected by a transmission. This helps to shorten the power transmission path, thereby reducing the loss in the power transmission process, improving the accuracy and response speed of rotation, and making the structure of the rotating device 25 more compact, thus improving the structural compactness.

[0044] Furthermore, combined Figure 1 and Figure 2 As shown, the main unit 20 also includes a heating element 26, which is disposed in the air duct 211 and located above the control board 24. The heating element 26 is connected to the control board 24.

[0045] In other words, the heating element 26 can heat the airflow within the air duct 211, thereby allowing hot air to be blown out from the air outlet 2121. The heating element 26 above the control board 24 is directly connected to the control board 24, which facilitates the control board 24 to directly send control commands to the heating element 26. Moreover, the short distance between the heating element 26 and the control board 24 helps to shorten the signal transmission link between them, thereby effectively reducing signal attenuation, electromagnetic crosstalk, and transmission delay, improving the execution response speed of control commands and the acquisition accuracy of feedback signals, and thus improving the rationality of the layout. Furthermore, since the heating element 26 is located above the control board 24, that is, the control board 24 is located in the direction of airflow within the air duct 211. Located downstream of the control board 24, this design prevents the heat generated by the heating element 26 from dissipating to the control board 24. Furthermore, the air blown by the fan 22 provides cooling for the control board 24 and its related electronic components, preventing the risk of overheating during long-term operation and ensuring the reliability and stability of the control board 24. It also allows the heating element 26 to be positioned closer to the air outlet 2121, avoiding the increased heat generation and insufficient air outlet temperature caused by excessive distance between the heating element 26 and the air outlet 2121. This ensures that the air outlet temperature requirement is met while reducing the heat generation power of the heating element 26, thereby improving the layout rationality of the heating element 26 and the control board 24.

[0046] Alternatively, combined Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the main unit 20 also includes an essential oil atomizing bottle 27, which is disposed on the surface of the first housing 212 and located above the control board 24. The essential oil atomizing bottle 27 is connected to the control board 24.

[0047] The essential oil atomizing bottle 27 is located on the surface of the first housing 212. This allows the essential oil atomizing bottle 27 to not occupy the space inside the air duct 211, avoiding obstruction or interference with the airflow within the air duct 211. It also facilitates the installation, removal, and replenishment of essential oil according to different user needs. Furthermore, the mist outlet of the essential oil atomizing bottle 27 faces forward, ensuring that the direction of the mist outlet corresponds as closely as possible to the airflow direction of the air outlet 2121. This allows the essential oil molecules to be precisely applied to the treatment area along with the airflow at the air outlet 2121, preventing essential oil waste and improving the accuracy and reliability of essential oil treatments.

[0048] Furthermore, the essential oil atomizing bottle 27 is directly connected to the control board 24, which facilitates the control board 24 in sending control commands directly to the essential oil atomizing bottle 27. The short distance between the essential oil atomizing bottle 27 and the control board 24 also helps to shorten the signal transmission link between them, effectively reducing signal attenuation, electromagnetic crosstalk, and transmission delay. This improves the execution response speed of control commands and the accuracy of feedback signal acquisition, thereby enhancing the reliability and accuracy of the essential oil atomizing bottle 27. Also, since the essential oil atomizing bottle 27 is located above the control board 24, it can be positioned as high as possible on the first housing 212. This allows the direction of the atomizing nozzle of the essential oil atomizing bottle 27 to correspond as closely as possible to the area being treated (such as the head) during normal postures (such as sitting and bending over). This helps the essential oil molecules to act more precisely and directly on the treated area, avoiding essential oil waste and improving the accuracy and reliability of essential oil treatments.

[0049] Alternatively, combine Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the host 20 also includes a hair detector 28, which is disposed on the surface of the first housing 212 and is used to detect hair information. The hair detector 28 is located above the control board 24 and is connected to the control board 24.

[0050] The hair detector 28 is located on the surface of the first housing 212. This allows the hair detector 28 to be better aligned with the user's care area, avoiding obstruction by adjacent structures and avoiding blind spots caused by misalignment or orientation. This enables it to capture the temperature, humidity, and shape changes of the hair more directly and in real time. Furthermore, by maintaining a certain distance from the air outlet 2121, it also reduces the interference of airflow disturbance on the sensing signal, thereby effectively improving the accuracy of hair-related parameter detection and providing more reliable data support for intelligent styling and care adjustments.

[0051] For example, the hair detector 28 can collect relevant parameters of the hair during the styling process in real time (such as hair temperature, humidity, hair texture, hair direction, and distance between the air outlet 2121 and the hair, etc., but not limited to these), which helps the styling device 100 to automatically and intelligently match and adjust the air outlet temperature and wind speed. For example, it can automatically reduce the hot air temperature to avoid damage for fine and soft hair, and appropriately increase the wind speed and temperature to enhance the styling effect for coarse and hard hair. At the same time, it can accurately sense changes in the fluffiness of the hair and dynamically adjust the blow-drying strategy without repeated manual adjustments, realizing the intelligent generation of personalized styles from basic dry hair to fluffy and straight styles, effectively improving styling efficiency and consistency of styling results.

[0052] Optionally, when the hair detector 28 is an infrared sensor, it can emit infrared light to achieve non-contact and accurate detection of key parameters such as hair temperature, heat distribution, and surface humidity. It can quickly capture signals without direct contact with the hair strands, avoiding the problems of contact sensors being easily entangled by hair or becoming ineffective due to moisture. It can also provide real-time feedback on temperature differences in different areas of the hair, such as the temperature gradient between the roots and the ends, providing accurate data support for the hair care device 100 to automatically adjust the air outlet temperature and speed. At the same time, the infrared sensor has a fast response speed and can dynamically track the trend of hair temperature changes during the blow-drying process, avoiding local high temperature damage to the hair. It can also indirectly determine the dryness by monitoring the rate of heat loss from the hair, assisting the device in judging the progress of hair drying, and realizing intelligent and precise control from drying to styling.

[0053] Specifically, in combination Figure 6 As shown, the hair detector 28 is a time-of-flight sensor, which includes a transmitting unit, a receiving unit, a first cover plate 281, and a second cover plate 282. The receiving unit and the transmitting unit are spaced apart. The first cover plate 281 is disposed on the transmitting unit, and the second cover plate 282 is disposed on the receiving unit. The time-of-flight sensor (ToF sensor) is a non-contact optical detection sensor that accurately calculates the distance between the sensor and the target by measuring the flight time of a modulated light signal from emission to reception after reflection from the target. It can directly output accurate distance values.

[0054] Understandably, the transmitting unit is used to transmit signals, and the receiving unit is responsible for receiving the reflected detection signals. The transmitting unit and the receiving unit are spaced apart from each other, which can prevent the transmitted signals of the transmitting unit from directly interfering with the receiving unit and ensure the purity of the received signals. The transmitting unit and the receiving unit are respectively provided with a first cover plate 281 and a second cover plate 282. The first cover plate 281 is beneficial for optically collimating the detection signals output by the transmitting unit and improving the directionality of the transmitted signals. The second cover plate 282 is beneficial for reducing the interference of ambient light and other irrelevant light on the receiving unit. Therefore, through the coordinated work of the two cover plates, the accuracy of distance detection and anti-interference ability can be further improved.

[0055] Furthermore, when the hair detector 28 is a time-of-flight sensor (i.e., a distance sensor), it can accurately detect the distance between the air outlet 2121 and the hair in real time. Based on the distance, it automatically adjusts the air outlet temperature and wind speed. When the distance is too small, it automatically lowers the temperature to avoid high-temperature damage to the hair. When the distance is too large, it appropriately increases the wind speed and temperature to ensure styling efficiency. At the same time, the distance sensor can help identify the volume and layering of the hair and dynamically adjust the blow-drying strategy. For example, for the root area that needs a voluminous effect, it reminds the user to maintain an appropriate distance and match a strong wind speed for styling. For the ends of the hair that need a smooth effect, it reminds the user to reduce the distance and lower the wind speed to smooth frizz, thereby achieving personalized and refined intelligent styling and effectively improving the consistency and aesthetics of the styling effect.

[0056] Furthermore, combined Figure 1 , Figure 2 and Figure 5 As shown, the first housing 212 has an air outlet 2121, which is connected to the air duct 211. The main unit 20 also includes a physiotherapy device, which is disposed in the air duct 211 and connected to the control board 24. The physiotherapy device includes a physiotherapy lamp, which is located at the air outlet 2121 so that the physiotherapy light generated by the physiotherapy lamp is transmitted outward through the air outlet 2121.

[0057] The physiotherapy device is directly connected to the control board 24, which facilitates the control board 24 in sending control commands directly to the physiotherapy lamp. This reduces signal attenuation, electromagnetic crosstalk, and transmission delay, improves the execution response speed of control commands and the accuracy of feedback signal acquisition, thereby enhancing the reliability and accuracy of the physiotherapy device. Furthermore, the physiotherapy lamp is located at the air outlet 2121 of the first housing 212, allowing the therapeutic light generated by the lamp to smoothly pass through the air outlet 2121 and irradiate the outer treatment area, thus achieving a therapeutic effect on the treated area. In one embodiment, the physiotherapy lamp can emit far-infrared light with a wavelength of 1072nm, or it can be near-infrared light, ultraviolet light, etc. The therapeutic light can also include various different types of light.

[0058] Optionally, the therapy lamp can also be red or blue. Red light typically uses a low-energy wavelength of 630-660nm, which can penetrate the treatment area or scalp epidermis to reach the dermis, activating mitochondrial metabolism in hair follicles, delaying follicle atrophy, promoting scalp microcirculation, replenishing oxygen and nutrients to hair follicles, soothing mild scalp inflammation, repairing the scalp barrier, and helping to strengthen and nourish hair, resulting in thicker new hair. It also has an auxiliary effect on improving mild to moderate hair loss and scalp sensitivity. Blue light primarily uses a low-energy wavelength of 415-460nm, acting on the scalp surface to precisely inhibit the growth of harmful bacteria such as Malassezia, relieving dandruff and scalp itching from the root. It can also regulate excessive sebum secretion, reducing oily scalp and preventing oil blockage of hair follicles, while soothing mild folliculitis caused by oil blockage. In summary, therapy lamps can improve the scalp growth environment and are especially suitable for most common scalp types, such as oily scalps, seborrheic alopecia, and combination scalps.

[0059] Furthermore, the physiotherapy device is located inside the air duct 211, which means it is located inside the first housing 212. The first housing 212 can provide structural protection for the physiotherapy device, preventing it from being bumped or corroded by dust, thus ensuring its normal operation. Moreover, the physiotherapy device does not occupy the external area of ​​the first housing 212, which can effectively reduce the overall space occupied by the nursing device 100 and improve the structural compactness. In addition, the light beam of the physiotherapy lamp is oriented in the same direction as the air outlet 2121, so that the range of the physiotherapy light emitted by the physiotherapy lamp can overlap with the air outlet 2121 as much as possible. This means that the physiotherapy light and air energy can be precisely applied to the nursing area, thereby achieving simultaneous blowing and physiotherapy, taking into account both the aesthetic effect and the nursing effect.

[0060] Alternatively, combined Figure 1 , Figure 2 and Figure 5 As shown, the main unit 20 also includes a negative ion device 29, which is disposed in the air duct 211 and connected to the control board 24. The negative ion device 29 is located at the air outlet 2121 to generate air with negative ions at the air outlet 2121.

[0061] The negative ion device 29 is directly connected to the control board 24, which allows the control board 24 to directly send control commands to the negative ion device 29, thereby reducing signal attenuation, electromagnetic crosstalk and transmission delay, improving the execution response speed of control commands and the acquisition accuracy of feedback signals, and thus improving the working reliability and accuracy of the negative ion device 29. The negative ion device 29 is located at the air outlet 2121, so that the negative ions generated by the negative ion device 29 can be accurately applied to the treatment area with the airflow at the air outlet 2121, thereby ensuring the treatment effect of negative ions.

[0062] In detail, the negative ion device 29 can generate negative charges. When the negative charge comes into contact with the treatment area or hair, it can quickly neutralize the positive static electricity generated by friction and dryness, eliminate the problems of frizz and flyaways caused by charge repulsion, make the hair more smooth and easy to comb, and prevent static electricity from attracting dust. The negative charge can also cause the raised hair cuticles to shrink and close, reduce the gaps in the hair cuticle, lock in the moisture of the cortex, relieve the problem of dry hair, restore the natural shine of the hair, and allow the hair moisture to evaporate evenly and delicately, reducing the time of high temperature treatment and the further damage to the hair cuticles caused by rapid moisture loss, indirectly reducing high temperature damage, and making it more suitable for dry, frizzy, and fragile hair after perming and dyeing.

[0063] In addition, the negative ion device 29 is located inside the air duct 211, that is, inside the first housing 212. The first housing 212 can provide structural protection for the negative ion device 29, avoiding the risk of impact and dust corrosion, thereby ensuring the normal operation of the negative ion device 29. Furthermore, the negative ion device 29 does not occupy the external area of ​​the first housing 212, which can effectively reduce the overall space occupied by the care appliance 100 and improve the structural compactness. The negative ion dispersion direction of the negative ion device 29 is the same as the direction of the air outlet 2121. This helps to ensure that the negative ions emitted by the negative ion device 29 are consistent with the air outlet 2121, so that the negative ions are precisely applied to the care area under the airflow at the air outlet 2121, thereby achieving simultaneous blowing and negative ion maintenance, taking into account both the aesthetic effect and the care effect.

[0064] Specifically, in combination Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the first housing 212 forms a wiring channel 2122. The inlet end 2123 and the outlet end 2124 of the wiring channel 2122 are both connected to the air duct 211. The inlet end 2123 is located below the fan 22, and the outlet end 2124 is located above the fan 22. The main unit 20 also includes a power cord 291. One end of the power cord 291 is connected to the power board 11, and the other end of the power cord 291 is connected to the control board 24. The power cord 291 passes through the air duct 211 and the wiring channel 2122 so that the part located in the wiring channel 2122 avoids the fan 22.

[0065] Understandably, one end of the power cord 291 is connected to the power board 11 and extends to a position below the fan 22 inside the air duct 211. Since the air duct 211 and the wiring channel 2122 are connected, the other end of the power cord 291 first passes through the inlet end 2123 of the wiring channel 2122 connected to the air duct 211, and then extends along the wiring channel 2122 to the outlet end 2124 of the wiring channel 2122 connected to the air duct 211. The other end of the power cord 291 then passes through the air duct 211. The internal fan 22 is positioned above the control board 24. This arrangement ensures that the power cable 291 can be smoothly connected to the power board 11 and the control board 24. At the same time, the cable routing channel 2122 avoids the fan 22, preventing the airflow generated by the fan 22 from pulling and loosening the power cable 291. This ensures the connection stability of the power cable 291 and also prevents the power cable 291 from contacting, tangling, or interfering with the rotation of the fan 22, thereby ensuring the working stability and safety of the power cable 291.

[0066] Furthermore, combined Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the first housing 212 includes a first inner housing 2125 and a first outer housing 2126. The first inner housing 2125 has an air duct 211, an inlet end 2123 and an outlet end 2124. The first outer housing 2126 is disposed on the outside of the first inner housing 2125, and a wiring channel 2122 is formed between the first outer housing 2126 and the first inner housing 2125.

[0067] In other words, the first outer shell 2126 surrounds the outside of the first inner shell 2125. This provides a double structural protection for the internal structure of the first inner shell 2125, improving the structural reliability of the host 20. On the other hand, it also helps to define the wiring channel 2122 between the host and the first inner shell 2125, allowing the power line 291 and the fan 22 to be physically isolated, avoiding interference between them, thereby improving the rationality of the layout and the simplicity of the structure.

[0068] Specifically, in combination Figure 1 , Figure 2 and Figure 7 As shown, the main unit 20 also includes an ambient light 292, which is disposed on the surface of the second housing 213 and is connected to the control board 24.

[0069] Understandably, the second housing 213 can serve as a load-bearing support for the ambient light 292, and the ambient light 292 is located on the surface of the second housing 213. This allows the lighting effect of the ambient light 292 to be exposed, thereby improving scene adaptability and visual aesthetics. It also facilitates the maintenance and replacement of the ambient light 292, which can be done without disassembling the second housing 213, thus reducing later maintenance costs. It can also prevent the ambient light 292 from interfering with other internal components of the main unit 20 during operation, thereby ensuring the operational stability of the nursing device 100. The ambient light 292 is directly connected to the control board 24, which makes it easy for the control board 24 to send control commands directly to the ambient light 292, thereby reducing signal attenuation, electromagnetic crosstalk and transmission delay, improving the execution response speed of control commands and the acquisition accuracy of feedback signals, and thus improving the operational reliability and accuracy of the ambient light 292.

[0070] Alternatively, the ambient light 292 surrounds the surface of the second housing 213, which helps the light emitted by the ambient light 292 to diffuse evenly outward from the outer periphery of the second housing 213, thereby forming a wide range of lighting effects, enhancing the visual atmosphere and aesthetics, and also fitting the arc shape of the main unit 20, thus making it easier for users to intuitively perceive the status of the care device 100 through the ambient light 292.

[0071] Alternatively, the ambient light 292 can be constructed as a light strip that extends along the length of the second housing 213. This allows the light emitted by the light strip to match the arc shape of the main unit 20, thereby improving the harmony of the ambient light 292 and facilitating the installation and removal of the light strip. This, in turn, enriches the scene adaptability of the care appliance 100 and enhances the user experience.

[0072] According to some optional embodiments of the present invention, in combination Figure 1 , Figure 2 and Figure 7 As shown, the nursing device 100 also includes a lifting device 30, which is disposed between the housing 21 and the base 10 to selectively lift the housing 21. The housing 21 is connected to the base 10 via the lifting device 30, which helps the base 10 provide a stable support for the main unit 20, avoiding the risk of shaking or tipping during use and ensuring the stability of the main unit 20.

[0073] Specifically, a lifting device 30 is provided between the main unit 20 and the base 10. The base 10 can provide a stable support for the lifting device 30, ensuring the working stability of the lifting device 30. The lifting device 30 can be flexibly raised and lowered according to user needs to adjust the height of the main unit 20. This allows the nursing device 100 to adapt to the needs of users with different heights and nursing postures, thereby improving the adaptability and flexibility of the nursing device 100.

[0074] For example, when a user uses the nursing device 100 to blow air onto their head, the user can raise or lower the main unit 20 according to their needs using the lifting device 30, so that the air outlet can be accurately aimed at the head, thereby ensuring the nursing effect of the nursing device 100; when the nursing device 100 is not in use, the user can lower the main unit 20 to the lowest position using the lifting device 30, reducing the overall space occupied by the nursing device 100, and also making it easier to store and move the nursing device 100.

[0075] Specifically, in combination Figure 1 , Figure 2 and Figure 7 As shown, the lifting device 30 includes a first rod 31 and a second rod 32. The first rod 31 is disposed on the base 10 and has a first positioning part. The second rod 32 is disposed on the housing 21 and is sleeved on the first rod 31. The second rod 32 is movable relative to the first rod 31 and has a second positioning part. There are multiple of one type of the first positioning part and the second positioning part, so that another type of the first positioning part and the second positioning part can be positioned and engaged with any one of the first type.

[0076] Understandably, the first rod 31 is connected to the base 10, and the second rod 32 is connected to the housing 21. The first rod 31 and the second rod 32 are sleeved together. The relative movement between the first rod 31 and the second rod 32 can realize the relative movement between the main unit 20 and the base 10. The first rod 31 bears the weight of the main unit 20 and the second rod 32, and the base 10 can provide stable support for the first rod 31. This makes the main unit 20 more stable when working. The second rod 32 moves relative to the first rod 31 along the length of the first rod 31. This can increase or decrease the distance between the main unit 20 and the base 10, thereby achieving a precise adjustment of the height of the main unit 20 and meeting the height adaptation needs of the nursing device 100 in different usage scenarios.

[0077] Furthermore, the coaxial sleeve of the first rod 31 and the second rod 32 can create a directional guiding effect, strictly constraining the lifting trajectory of the second rod 32, ensuring the coaxiality and smoothness of the second rod 32 during the lifting process, and effectively avoiding problems such as swaying and jamming of the second rod 32 during lifting. At the same time, the sleeve structure can increase the contact area between the rods, effectively improving the overall structural rigidity and load-bearing stability of the lifting device 30, which can stably support the weight of the main unit 20 and adapt to the force requirements of different lifting heights. In addition, the structure has a clear fit and a simple structure, which is convenient for production and processing.

[0078] In particular, the rigid connection structure of the first rod 31 and the second rod 32 is also conducive to stabilizing the relative rotation between the first body and the second body, and avoiding tilting and swaying problems when the first body and the second body rotate.

[0079] Furthermore, a first positioning part is provided on the first rod 31, and a second positioning part is provided on the second rod 32. When the first rod 31 and the second rod 32 move relative to each other to a designated position, the first positioning part and the second positioning part engage in positioning. This allows the main unit 20 to move to the appropriate position, and the first rod 31 and the second rod 32 to form a precise locking position, thereby ensuring the positional stability of the nursing device 100 during operation, preventing the risk of accidental slippage of the main unit 20, and ensuring the operational reliability of the nursing device 100. For example, the first positioning part and the second positioning part can be a locking protrusion and a locking buckle, or a through hole and a convex circle, thereby ensuring the positioning engagement between the first positioning part and the second positioning part.

[0080] Alternatively, one of the first positioning part and the second positioning part may be multiple, while the other may be a single unit. Taking multiple first positioning parts and a single second positioning part as an example, the multiple first positioning parts are arranged at intervals along the length of the first rod 31. The second positioning parts are positioned and cooperate with the corresponding first positioning parts according to actual needs. This allows the lifting device 30 to adapt to the needs of different users' heights, different care areas, and different care postures, thereby improving the adaptability and flexibility of the care device 100. It also ensures the stability of the lifting device 30, eliminating the need for an additional locking structure and improving the simplicity of the overall structure. For example, the first positioning part can be a positioning hole, and the second positioning part can be a positioning protrusion or a positioning ball.

[0081] According to some optional embodiments of the present invention, in combination Figure 1 Figure 5 As shown, the top of the housing 21 has an air outlet 2121, and the projection of the air outlet 2121 on the horizontal plane is located on the front side of the base 10.

[0082] The above arrangement allows the air outlet to be closer to the user's care area. This makes it easier for the air outlet 2121 to approach the care area on the same vertical plane as the base 10. This helps the airflow to cover the user's care area more directly and accurately, reducing airflow loss and obstruction during the flow process. It also ensures that the airflow range matches the user's actual space, allowing the user to receive a more sufficient and uniform airflow for their target needs, thereby improving the practicality and adaptability of the care device 100.
