Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, and in particular discloses an anti-interference structure for an intelligent hair dryer. Background Technology

[0002] Traditional hair dryers, when integrating multi-functional modules (such as infrared ranging and ion generation), generally suffer from severe electromagnetic interference and chaotic module layout. For example, infrared sensors are susceptible to interference from high-voltage electric fields, leading to ranging distortion; the concentration of water ions and negative ions is uneven after mixing; poor heat dissipation of heating components causes high-temperature aging; and when multiple modules share a single air duct, airflow becomes turbulent and inefficient. Existing technologies often employ simple physical isolation or a single shielding layer, failing to balance signal stability with structural compactness, resulting in bulky hair dryers, limited hair care effects, and a poor user experience. Utility Model Content

[0003] In order to overcome the technical problems of severe interference and chaotic layout of multi-functional modules in the existing technology, the purpose of this utility model is to provide an anti-interference structure for an intelligent blower with a simple, orderly layout and anti-interference.

[0004] To achieve the above objectives, this utility model provides an anti-interference structure for an intelligent hair dryer, comprising an air outlet guide tube disposed at the air outlet end of the hair dryer. The air outlet guide tube has air holes, and functional components are disposed within the air holes. The functional components include an infrared distance sensor, a water ion generator, a negative ion generator, and a heating wire frame. A main cover is disposed within the air outlet guide tube, and the main cover has three independent channels. The three independent channels are respectively used for the infrared distance sensor, the water ion generator, the negative ion generator, and the heating wire frame. The heating wire frame and the negative ion generator are used in conjunction with the same independent channel.

[0005] Furthermore, the main housing has a cylindrical structure with blind grooves, and multiple partitions are provided on the bottom wall of the main housing. The independent channel where the infrared distance sensor is located is surrounded by at least two partitions.

[0006] Furthermore, the independent channel where the infrared distance sensor is located is a closed channel, and a light-transmitting window is provided at one end of the air outlet near the air vent. The light-transmitting window corresponds to the transmitting and receiving ends of the infrared distance sensor.

[0007] Furthermore, the independent channel corresponding to the negative ion generator is ring-shaped, and the independent channel corresponding to the negative ion generator surrounds the independent channel corresponding to the water ion generator and the independent channel corresponding to the infrared distance sensor.

[0008] Furthermore, the main housing has a second mounting shell and a disc bracket connected to the second mounting shell. The second mounting shell is arranged around the disc bracket. The disc bracket is connected to the inner wall of the main housing by a plurality of positioning ribs arranged in a ring array. An annular vent is formed between the second mounting shell and the disc bracket. The annular vent is the first independent channel, which is used in conjunction with the heating wire frame and the negative ion generator. The disc bracket has a first through hole and a first blind hole. The first through hole is the second independent channel, which is used in conjunction with the water ion generator. The first blind hole is the third independent channel, which is used in conjunction with the infrared distance sensor.

[0009] Furthermore, the disc support has a first blind hole, the bottom wall of the first blind hole is provided with a first through hole, and the bottom wall of the first blind hole is provided with first strips on both sides, the first strips forming an independent channel for installing the water ion generator around the outer periphery of the first through hole.

[0010] Furthermore, the heating wire frame includes a first housing and an insulating heat insulation plate disposed on the outside of the first housing. A first limiting plate is provided inside the first housing, and a mounting groove for installing a water ion generator is provided on the first limiting plate. The bottom wall of the mounting groove is provided with an air passage for use with the water ion generator. The airflow generated by the blowing device mixes with the water ions generated by the water ion generator through the air passage and is then blown out through the air hole.

[0011] Furthermore, the first housing has a first conical portion at the end near the air outlet, and the inner diameter of the first conical portion gradually increases from the air inlet to the air outlet.

[0012] Furthermore, the outer wall of the first housing is provided with multiple ribs, which are arranged in a ring array in pairs on the outer circumferential surface of the first inner housing. A first slot is formed between two adjacent ribs, and the insulating heat insulation plate is inserted into the first slot along the axial direction and detachably connected to the first housing.

[0013] Furthermore, one end of the insulating heat insulation plate is provided with a first limiting plate, and a second slot is formed between the first limiting plate and the insulating heat insulation plate. The opening direction of the second slot is perpendicular to the opening direction of the first slot. A second limiting plate is provided between the two adjacent ribs to block and abut against the limiting plate. When the insulating heat insulation plate is inserted into the first slot along the axial direction of the main cover and continues to move, the second limiting plate enters the second slot. The first limiting plate and the second limiting plate block and abut against each other to prevent the insulating heat insulation plate from coming out in the radial direction.

[0014] Furthermore, the main housing includes a hollow first mounting shell and a second mounting shell that are snap-fitted together, and the disc bracket and the second mounting shell are integrally injection molded.

[0015] The partition is set on the bottom wall of the first blind hole of the disc bracket. There are 4 partitions. An installation hole is opened between two adjacent partitions to form an independent channel. The 4 partitions form two independent channels for installing the infrared distance sensor and the negative ion generator, respectively. The heat generated by the heating wire frame flows out through the annular vent between the disc bracket and the main cover. This annular vent serves as a heat channel. The independent channel formed by the first plate surrounding the first through hole is used to install the water ion generator.

[0016] Furthermore, the inner wall of the independent channel where the heating wire frame is located is provided with a high-temperature resistant insulation layer, and the high-temperature resistant connector is wrapped around the outer periphery of the heating wire frame.

[0017] Furthermore, a connecting ring is provided between the disc support and the air outlet guide tube, and the connecting ring is used to connect with the nozzle of the external air blowing device.

[0018] Furthermore, the connecting ring is a magnetic component, and the nozzle of the external blower is provided with a magnetic ring that cooperates with and is attracted to the magnetic component.

[0019] Furthermore, the disc support is provided with a baffle that covers the first blind hole. The baffle is provided with a light-transmitting window for use with an infrared distance sensor. The baffle is provided with a central hole for water ions generated by the water ion generator to pass through. The central hole is connected to the first through hole.

[0020] Furthermore, a distance n is provided between the infrared distance sensor and the baffle, where 0.1mm≤n≤0.4mm.

[0021] Furthermore, the anti-interference structure also includes a handle portion that cooperates with the air outlet guide tube. The handle portion includes a hollow inner handle shell and a hollow outer handle shell. The side wall of the air outlet guide tube is provided with a connecting section that extends into the inner handle shell. The outer handle shell is fitted onto the inner handle shell and the connecting section. The outer handle shell is detachably connected to the inner handle shell and the air outlet guide tube, respectively. The inner handle shell is provided with a fan assembly for generating airflow. The inner cavity of the inner handle shell is connected to the air hole. The airflow generated by the fan assembly passes through the negative ion generator and the heating coil and is blown out through the air hole.

[0022] Furthermore, the inner wall of the handle inner shell is provided with a limiting strip, and the outer wall of the connecting section is provided with a limiting groove for accommodating the limiting strip. The handle inner shell includes two fan-shaped shells that are assembled and connected. The limiting strip is accommodated in the limiting groove to restrict the handle inner shell from detaching from the connecting section.

[0023] This invention's anti-interference structure achieves efficient operation and stability of multiple functional modules through an independent channel design. The air outlet guide tube contains multiple independent channels, separated by partitions inside the main housing, ensuring that functional components such as the infrared distance sensor, water ion generator, negative ion generator, and heating coil bracket do not interfere with each other. The disc support is precisely connected to the main housing to form air vents, and each functional component, through its connection with its respective channel, can perform its function independently, ensuring high efficiency and stability during equipment operation.

[0024] The beneficial effects of this invention are as follows: The anti-interference structure of this invention, through innovative structural design, greatly improves the stability and multi-functional integration of the device. The design of multiple independent channels ensures the mutual isolation of functional modules such as infrared sensing, water ion generation, and negative ion generation, effectively avoiding interference between different functions and enabling each function to work independently and efficiently. The overall system design not only achieves higher performance requirements but also significantly optimizes the user experience. Compared with existing technologies, this invention provides a more efficient, safer, and more simply and stably designed anti-interference structure for a blower device. Attached Figure Description

Detailed Implementation

[0041] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0042] Please see Figures 1 to 14As shown, the present invention discloses an anti-interference structure for an intelligent hair dryer, comprising an air outlet guide tube 1 disposed at the air outlet end of the hair dryer, the air outlet guide tube 1 having an air hole 11, and a functional component 12 disposed within the air hole 11; the functional component 12 includes an infrared distance sensor 21, a water ion generator 22, a negative ion generator 23, and a heating wire frame 24; the air outlet guide tube 1 is provided with a main cover 2, the main cover 2 having three independent channels, the three independent channels respectively corresponding to the infrared distance sensor 21, the water ion generator 22, the negative ion generator 23 and the heating wire frame 24, the heating wire frame 24 and the negative ion generator 23 working together in the same independent channel.

[0043] Specifically, please refer to Figure 3 , Figure 4 and Figure 5 As shown, the disc bracket 3 in this utility model is designed as a support structure for the multi-functional component 12 inside the hair dryer. The disc bracket 3 has a first blind hole 33, and the bottom wall of the first blind hole 33 is provided with a first through hole 34. A first strip 35 is provided around the first through hole 34, and the first strip 35 forms an independent channel around the outer periphery of the first through hole 34, which is specifically used to install the water ion generator 22. The water ion generator 22 is electrically connected to the circuit board of the hair dryer through the first through hole 34, and releases the generated water ions into the air outlet channel through this channel to mix with the hot air, thereby improving the moisture and smoothness of the hair.

[0044] Specifically, four partitions 25 are integrally formed on the bottom wall of the first blind hole 33 of the disc bracket 3. The spacing of these partitions 25 forms two independent channels through the opening of mounting holes. One channel is used to install the infrared distance sensor 21, and the other channel is used to allow one end of the negative ion generator 23 to extend and be limited. The channel design ensures accurate transmission of infrared signals. One end of the channel is provided with a light-transmitting window, which is precisely aligned with the transmitting and receiving ends of the infrared sensor to ensure accurate emission and reflection of infrared rays. This allows for real-time monitoring of the distance between the air outlet and the user's hair to dynamically adjust the wind speed and temperature.

[0045] Specifically, the negative ion generator 23 is connected to the air outlet channel through its dedicated channel. An annular air hole 11 is formed between the disc support 3 and the main cover 2. This air channel acts as a heat channel, carrying away the heat generated by the heating wire frame 24, ensuring that the surrounding components are not affected by overheating and maintaining the stable operation of the equipment.

[0046] In this embodiment, the negative ion generator 23 is installed on the main housing 2 and extends into the thermal channel between two adjacent insulating heat insulation plates 242, so that the negative ions it generates can be evenly mixed with the hot air and then blown out.

[0047] Compared with existing technologies, this invention effectively isolates different functional modules (such as the infrared distance sensor 21, water ion generator 22, and negative ion generator 23) through the design of the disc bracket 3 and three independent channels, reducing interference between them. The independent enclosed infrared sensing channel is equipped with a light-transmitting window, which effectively improves the accuracy of infrared ranging, enabling more precise detection of the distance between the air vent and the user's hair, and adjusting the wind speed and temperature according to the real-time distance, thereby providing a personalized hair care experience.

[0048] Specifically, the air outlet guide tube 1 of the blower is connected to the main casing 2 by six positioning ribs 32. The six positioning ribs 32 are evenly spaced, dividing the annular air hole 11 into six arc-shaped segments to form a stable airflow channel. The first through hole 34 is located at the center of the annular air hole 11 and is used to guide the airflow to mix with the water ions generated by the water ion generator 22 and blow it out through the central hole 312. The first blind hole 33 is off-center and distributed around the first through hole 34. The infrared distance sensor 21 is installed in the first blind hole 33, close to one arc-shaped segment of the annular air hole 11, to ensure that its sensing area is not directly interfered with by the airflow. The generating end of the negative ion generator 23 is located in another arc-shaped segment of the annular air hole 11, which is far away from the infrared distance sensor 21 to avoid interference of the negative ion airflow with the sensor signal, while ensuring that the negative ions are evenly distributed in the airflow.

[0049] The water ion generator 22 and negative ion generator 23, through specially designed independent channels, improve hair's moisture retention and anti-static properties. The thermal channel design between the disc support 3 and the air vent 11 effectively dissipates the heat generated by the heating element frame 24 into the air duct, preventing overheating from affecting the functional modules and improving the stability and lifespan of the equipment. The compact design and modular structure of the overall design make assembly more efficient and also facilitate maintenance and replacement. Compared with traditional technologies, this solution not only improves the functional integration of the equipment but also optimizes the coordination of various functions, providing a more intelligent and comfortable user experience.

[0050] Specifically, please refer to Figure 2 and Figure 3 In this embodiment, the heating element frame 24 adopts a surrounding heat source structure, which is composed of a first housing 241 arranged in a cylindrical shape and multiple insulating heat insulation plates 242 installed on its outer wall. The first housing 241 is made of high temperature resistant insulating material, and its structure is compact. The hollow interior is used to install multifunctional components 12 such as infrared distance sensor 21, water ion generator 22 and negative ion generator 23 corresponding to the main cover 2.

[0051] Specifically, multiple insulating heat insulation plates 242 are evenly distributed around the outer circumference of the first housing 241. Each insulating heat insulation plate 242 is made of mica material and is used to support and fix the electric heating wire. The mica plate has extremely high dielectric strength, which can effectively prevent the electric heating wire from being electrically broken down or short-circuited under high temperature or high voltage. This ensures the electrical safety of the heating plate when it is energized. The electric heating wire is wound in a wave pattern on the insulating heat insulation plate 242, forming an integrated heating unit with the insulating heat insulation plate 242. When energized, the electric heating wire heats up, and the insulating heat insulation plate 242 is heated as a whole through heat conduction. The heat is then conducted to the first housing 241 and the external annular air duct, so that the cold air entering the air duct is quickly heated to form hot air.

[0052] Specifically, please refer to Figure 12 and Figure 13 As shown, the insulating heat insulation plates 242 maintain equidistant gaps to form negative ion channels and heat convection channels for airflow, while maintaining heat dissipation efficiency. The heating wire's voltage output is controlled by the circuit board of the blower, and temperature regulation is achieved in conjunction with the feedback signal from the infrared ranging module. The entire heating wire frame 24 is installed on the inner wall of the main housing 2, and the distance m from the inner wall of the main housing 2 to the top of the insulating heat insulation plate 242 is 1.5mm, ensuring effective heat transfer and structural stability.

[0053] In this embodiment, a first slat 2410 is provided inside the first housing 241, and a mounting groove 2411 is provided on the first slat 2410 for mounting the water ion generator 22. The bottom wall of the mounting groove 2411 is provided with an air passage 2412, which works in conjunction with the working mechanism of the water ion generator 22. Specifically, the airflow generated by the fan assembly of the blower passes through the air passage 2412 and mixes with the water ions generated by the water ion generator 22 before being blown out through the air passage 11.

[0054] This structural design, by rationally combining the water ion generator 22 with the airflow channel, ensures that during the blow-drying process, the airflow not only carries warm air but also water ions, providing users with a healthier blow-drying experience. Water ions help moisturize hair, reduce static electricity, and improve hair quality, enhancing its shine and smoothness. The combination of the airflow channel 2412 and the water ion generator 22 ensures thorough mixing of the airflow and water ions, thereby improving the efficiency of the water ion blow-drying process and enhancing the overall functionality of the device.

[0055] This structural design enhances the versatility of the hair dryer, enabling it to not only provide warm airflow but also improve air quality and hair care effects through the action of water ions and negative ions, bringing users a more comfortable and healthier experience.

[0056] Specifically, please refer to Figure 2 , Figure 6and Figure 7 As shown, in this embodiment, one end of the first mounting shell 26 has an air inlet 261 for use with the vortex fan of the blower. During use, the vortex fan guides external airflow through the air inlet 261 into the main shell 2, where it is heated by the heating wire frame 24 and then discharged through the air hole 11. The main shell 2 serves as the external protection and directional structure for the air outlet guide shroud. Its end near the air outlet has a first conical portion 243, the inner diameter of which gradually increases from the air inlet 261 towards the air outlet. This conical flare design optimizes the air outlet path and airflow distribution, allowing the heated air to gradually expand as it passes through the annular air duct, reducing wind speed and local pressure, thereby achieving a more uniform and gentle hot air output. The conical structure also has air-gathering and guiding functions, effectively preventing airflow turbulence and improving blowing efficiency and user comfort.

[0057] Furthermore, the increased inner diameter of the air outlet reduces the direct impact of hot air on the infrared sensor and ion module outlet area, preventing component aging or signal interference caused by high temperatures. In actual use, the inner wall of the conical section can be coated with a heat-insulating and reflective layer to further improve thermal efficiency and protect the outer shell material from deformation due to prolonged high-temperature use. This structure complements the surrounding heating structure of the heating coil 24, forming a good hot air channel system that ensures a high degree of coordination and integrated operation of various functional modules in terms of temperature control, safety, and airflow.

[0058] Specifically, please refer to Figure 7 This invention further optimizes the assembly structure of the heating wire frame 24, improving the stability, detachability, and safety performance of the heating module. Multiple ribs 244 are provided on the outer wall of the main housing 2, arranged in pairs and evenly distributed in a ring array on the outer circumferential surface of the first inner housing. A first slot 245 for installing the insulating heat insulation plate 242 is formed between two adjacent ribs 244. The slot extends axially and provides good guiding and supporting functions. The insulating heat insulation plate 242 slides into the first slot 245 along the axial direction of the main housing 2, achieving a detachable connection with the main housing 2.

[0059] This design not only makes the installation of the insulation and heat insulation board 242 faster, but also facilitates maintenance and replacement, making it particularly suitable for complex structures with multiple heat-generating modules.

[0060] In this embodiment, to further enhance the fixing effect of the insulating heat insulation plate 242, a first limiting plate 2421 is provided at one end of the insulating heat insulation plate 242. The first limiting plate 2421 and the main body of the insulating heat insulation plate 242 form a second slot 2422 with a transverse opening. In cooperation with this, a second limiting plate 2441 is integrally formed between two adjacent ribs 244. The installation direction of the second limiting plate 2441 is perpendicular to the first slot 245. During actual installation, when the insulating heat insulation plate 242 slides into the first slot 245 axially and is pushed into place, the second limiting plate 2441 on the main cover 2 automatically embeds into the second slot 2422 of the insulating heat insulation plate 242, realizing mutual contact between the two limiting plates. Through this bidirectional limiting structure, the insulating heat insulation plate 242 is not only firmly restricted within the sliding trajectory of the main cover 2 in the axial direction, but its radial dislodgement is also reliably prevented, avoiding loosening or falling off due to vibration or thermal expansion during use.

[0061] Compared to traditional methods of fixing the insulation and heat insulation board 242 with screws or adhesive, this invention adopts a slot-limiting fit structure, which not only achieves rapid assembly and disassembly but also enhances the stability and vibration resistance of the structure. The insulation and heat insulation board 242 is guided and installed through the first slot 245, precisely fitting against the outer wall of the main housing 2; the second slot 2422 and the second limiting plate 2441 of the main housing 2 form a vertical physical stop, preventing the insulation and heat insulation board 242 from loosening under thermal expansion, equipment movement, or external force, significantly improving the safety of equipment operation. This structure has good modularity, facilitating future equipment maintenance, upgrades, and customized development. In actual manufacturing, all slots and limiting structures can be made of high-temperature resistant engineering plastics or high-strength alloys, capable of withstanding thermal stress and long-term fatigue loads under high-temperature environments of electric heating wires.

[0062] Specifically, in this embodiment, the main housing 2 includes a hollow first mounting shell 26 and a second mounting shell 27 that are fastened together to form a stable outer shell structure, ensuring the integrity and structural stability of the equipment.

[0063] Please see Figure 6 As shown, the first mounting shell 26 and the second mounting shell 27 are connected by a tight fit and a locking mechanism to prevent loosening or deformation under high temperature or long-term use, thereby enhancing the durability and safety of the equipment.

[0064] Specifically, please refer to Figure 4 and Figure 5As shown, the disc bracket 3 and the second mounting shell 27 are integrally injection molded structures. This design allows the disc bracket 3 to better integrate with the shell, improving the overall mechanical strength and airtightness, while reducing production costs and assembly complexity. The inner wall of the independent channel where the heating wire frame 24 is located (i.e., the inner wall of the air outlet guide tube 1) is covered with a high-temperature resistant insulation layer. This insulation layer can effectively isolate the heat source from the heat conduction between it and the air outlet guide tube 1, preventing overheating from harming the human body.

[0065] Specifically, please refer to Figure 2 As shown, a connecting ring 4 is provided between the main cover 2 on the outer side of the disc support 3 and the air outlet guide tube 1. In this embodiment, the connecting ring 4 is a magnetic component, and the nozzle component of the external blower is provided with a corresponding magnetic ring. In use, the nozzle component and the air outlet guide tube 1 can be quickly assembled and disassembled through the magnetic attraction between the magnetic ring and the magnetic component. In actual use, a snap-fit ​​structure can be provided on the connecting ring 4, and the corresponding snap-fit ​​structure on the nozzle component of the external blower can be snapped into the connecting ring 4.

[0066] In another embodiment, a shock-absorbing collar is provided between the main cover 2 on the outer side of the disc support 3 and the air outlet guide tube 1. The shock-absorbing collar is used to reduce the vibration interference caused by the airflow in the air hole 11 to the functional components 12 in the independent channel.

[0067] The shock-absorbing collar is integrally molded from modified rubber, forming a ring structure. Its outer diameter fits tightly with the inner wall of the air outlet guide tube 1, while its inner diameter precisely matches the outer circumference of the main housing 2, achieving an interference fit or a limiting snap-fit ​​installation. The shock-absorbing collar is installed at the contact position between the main housing 2 and the air outlet guide tube 1, without affecting the structural integrity of the air vent 11 or obstructing the hot air flow path. Its flexible material has excellent vibration absorption capabilities. Under the action of high-speed airflow, when high-frequency airflow pulsations or turbulence are generated in the annular air duct, the shock-absorbing collar can effectively weaken the mechanical vibrations caused by these airflows, thereby reducing the vibration interference transmitted to the sensitive functional modules such as the infrared sensor, water ion generator 22, and negative ion generator 23 carried on the disc support 3.

[0068] The shock-absorbing collar not only serves as a buffer connection in the structure, but also possesses a certain degree of sealing performance due to its material properties. This prevents external gases or dust from seeping into the functional channels along the bracket connection points, thus affecting the module's operational stability. Simultaneously, the collar's compressibility simplifies the assembly process; it simply needs to be inserted into the corresponding slot before installing the disc bracket 3, and a tight contact is automatically formed after the bracket is installed, eliminating the need for additional fasteners or sealant. During use, especially at high wind speeds or in variable speed conditions, the shock-absorbing collar continuously absorbs airflow pulse fluctuations from the duct, keeping the entire functional component 12 system relatively stable. This avoids infrared signal errors, uneven ion release, or fatigue of electronic component solder joints caused by vibration, thereby significantly improving the equipment's operational reliability and functional consistency.

[0069] For details, please continue reading Figure 2 and combined Figure 3 As shown, a baffle 31 is provided at one end of the disc bracket 3 near the air outlet. In this embodiment, the baffle 31 is made entirely of a translucent acrylic panel, used in conjunction with the infrared distance sensor 21 to ensure that the infrared beam can be accurately emitted and received, and to accurately measure the distance between the air outlet and the hair. In addition, a central hole 312 is provided in the middle of the baffle 31 (in this embodiment, the central hole 312 is the ion diffusion mesh of the water ion generator 22), through which water ions generated by the water ion generator 22 enter the air outlet channel, optimizing the blowing effect, keeping the hair moist, and reducing static electricity.

[0070] Please see Figure 14 As shown, in this embodiment, the distance n between the infrared distance sensor 21 and the baffle 31 is set to 0.4 mm. This design aims to ensure stable operation of the infrared sensor's transmission and reception functions while avoiding unnecessary interference between the sensor and the baffle 31. A suitable distance n allows the infrared distance sensor 21 to maintain accurate distance detection during operation, ensuring it can accurately sense the position of the target object (such as hair), thereby optimizing the airflow and temperature adjustment of the hair dryer. Setting the distance n not only prevents the infrared signal from being blocked or deflected but also reduces potential errors, making the device's intelligent adjustment more precise and efficient.

[0071] Specifically, the airflow generated by the blower mixes with the water ions generated by the water ion generator 22 through the first through hole 34 and is then blown out through the central hole 312, achieving uniform mixing of airflow and water ions and improving the moisturizing effect. The distance t between the water ion generator 22 and the baffle 31 (see [reference]). Figure 12 The distance (as shown) is greater than the distance n between the infrared distance sensor 21 and the baffle 31, which protects the detection accuracy of the infrared distance sensor and improves the user experience.

[0072] In this embodiment, the anti-interference structure further includes a handle portion 5 that cooperates with the air outlet guide tube 1. The handle portion 5 consists of a hollow handle inner shell 51 and a handle outer shell 52. A fan assembly is provided inside the handle inner shell 51, and the generated airflow communicates with the outside through the air channel 11, driving the air outlet guide tube 1 to generate airflow. To ensure a tight connection between the handle inner shell 51 and the air outlet guide tube 1, a connecting section 13 extending into the handle inner shell 51 is provided on the side wall of the air outlet guide tube 1. This connecting section 13 is detachably connected to the handle inner shell 51.
