Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a hair dryer. Background Art

[0002] With the development of the economy and the improvement of people's living standards, people's requirements for quality of life are getting higher and higher, and a hair dryer is a must-have item for most families. In the existing technology, the angle between the air inlet center line of the hair dryer handle and the center line of the heating air duct is designed to be a right angle. When the air flow passes through the handle and enters the heating body, there is an extremely uneven diversion phenomenon on the end face of the heating body, that is, the air intake volume is large when the heating body is far away from the end of the handle, and the air intake volume is small when it is close to the end of the handle, resulting in uneven air outlet temperature, which makes the user experience poor. Utility Model Content

[0003] Based on this, it is necessary to provide a hair dryer to address the problem of uneven air outlet temperature caused by unreasonable handle angle design of the hair dryer.

[0004] A hair dryer comprises: a shell assembly, the shell assembly is provided with a mounting cavity, and the shell assembly is provided with an air outlet connected to the mounting cavity; a heating assembly, the heating assembly is arranged on the shell assembly and located in the mounting cavity; a handle assembly, the handle assembly is arranged on the shell assembly, the handle assembly is provided with an air supply cavity and an air inlet hole, the angle formed by the fluid flow direction in the air supply cavity and the blowing direction of the air outlet of the shell assembly is an acute angle, the air inlet hole, the air supply cavity, the mounting cavity and the air outlet are connected in sequence; a fan assembly, the fan assembly is arranged on the handle assembly and located in the air supply cavity.

[0005] The present application discloses a hair dryer in which a heating component is arranged in a housing component and is located in an installation cavity. This can provide physical protection for the heating component and prevent the heating component from being damaged by external collisions or squeezing. In daily use, if the hair dryer is accidentally bumped or dropped, the housing component can provide a certain buffer for the internal heating component, reducing the risk of damage to the heating component. At the same time, the housing component can also isolate the heating component from the user, preventing the user from directly contacting the high-temperature heating component and causing burns. This provides important safety protection for users, especially in home environments with children. The handle assembly is arranged on the housing assembly, and the angle formed by the fluid flow direction in the handle assembly and the blowing direction of the housing assembly is an acute angle. Optionally, the acute angle ranges from greater than 45° to less than 90°. Preferably, the acute angle of the present application is 87°. First, the inclined handle assembly is more in line with the natural drooping angle of the human hand, making the user more comfortable when holding the hair dryer. When a user holds a hair dryer with an angled handle assembly, their wrist can be in a relatively neutral position, reducing fatigue and discomfort caused by prolonged use, allowing the wrist to be more relaxed and improving user comfort. The angled handle also makes the hair dryer more convenient to operate, allowing users to more easily adjust the angle and direction of the hair dryer to better dry different parts of the hair. Furthermore, if the handle assembly and the housing assembly are set at a right angle, when the airflow flows through the handle assembly and then enters the heating assembly, there is an extremely uneven flow distribution phenomenon when the airflow flows through the end surface of the heating assembly. That is, the airflow inlet is large where the heating element is far from the handle end, and the airflow inlet is small when it is close to the handle end, resulting in uneven outlet air temperature. Therefore, when the acute angle formed by the air supply direction of the centerline of the handle assembly and the air outlet direction of the centerline of the housing assembly is less than 87°, the fan assembly drives the external airflow into the air inlet and through the air supply cavity. This allows the airflow to flow through the handle assembly and then into the mounting cavity, where it is more evenly distributed in the heating assembly for heating. This results in better temperature uniformity when the airflow is blown out from the outlet, greatly improving the user experience and making the hair dryer more competitive in the market.

[0006] In one embodiment, the angle formed by the length direction of the handle assembly and the length direction of the housing assembly is acute. Setting the angle formed by the handle assembly and the housing assembly at an acute angle facilitates airflow through the handle assembly into the mounting cavity and is more evenly distributed in the heating assembly for heating. This improves temperature uniformity when the airflow is blown out of the air outlet. Furthermore, the handle better fits the natural curve of the hand when held, allowing the palm and fingers to more comfortably wrap around the handle when holding the hair dryer, reducing hand fatigue.

[0007] In one embodiment, the housing assembly includes a nozzle assembly, a front shell assembly, and a rear shell assembly. The nozzle assembly is mounted on the front shell assembly, and the rear shell assembly is mounted on the front shell assembly. The nozzle assembly is provided with a blowing chamber, and the front shell assembly is provided with a heating chamber. The heating chamber and the blowing chamber are sequentially connected to form the mounting chamber. The basic structure of the housing assembly is formed by mounting the nozzle assembly on the front shell assembly and the rear cover assembly on the front shell assembly. The blowing chamber provided in the nozzle assembly can directional guide the air blown by the hair dryer, so that the air is blown more concentratedly to a specific area. When styling hair, the nozzle assembly can be aimed at the part of the hair that needs to be dried or shaped, ensuring that the hot air can accurately act on the target area, improving the styling effect and efficiency. Furthermore, the nozzle assembly mounted on the front end can, to a certain extent, protect the user from direct burns from the hot air. The presence of the nozzle assembly increases the distance from the heating assembly, reducing the risk of accidental contact with high-temperature airflow. Furthermore, mounting the nozzle assembly on the front shell assembly facilitates the user to replace different types of nozzles according to different needs. Users can easily install or remove nozzles with different functions according to their hairstyle, styling needs and usage scenarios to achieve a personalized user experience. The back cover assembly is combined with the front shell assembly to form an enclosed space, which protects the internal components of the hair dryer, such as the heating component and circuit board. It also prevents external factors such as dust and water vapor from entering the hair dryer and affecting its normal operation and service life. A heating chamber is set in the front shell assembly to provide a specific space for the heating component of the hair dryer, so that the air can be heated more evenly when flowing through the heating component, and the heat can be generated and transferred to the blowing chamber more concentratedly. This combination of installation chambers can shorten the time it takes for the hair dryer to reach the set temperature, improve blowing efficiency, and allow users to complete tasks such as hair drying or styling more quickly.

[0008] In one embodiment, the nozzle assembly includes a nozzle and a connector, wherein the nozzle is arranged on the connector, which is arranged on the front shell assembly, and the nozzle and the connector enclose the blowing chamber. By arranging the nozzle on the connector and the front shell assembly, the connector first provides a stable support and fixing structure for the nozzle. Compared with directly installing the nozzle on the front shell assembly, adding the connector can make the installation of the nozzle more secure and reliable, able to withstand various external forces that may be encountered during use, reduce the risk of the nozzle loosening, shifting or even falling off, and ensure that the nozzle always remains in the correct position during use, thereby ensuring the stability of the blowing effect. The nozzle and the connector enclose a blowing chamber, which can concentrate the airflow generated by the hair dryer in a relatively small space, making the airflow more concentrated and powerful, allowing the airflow to be blown out more directionally, reducing the diffusion and scattering of the airflow, and when the airflow passes through the blowing chamber, due to the limitation of space, the speed of the airflow increases, thereby enhancing the wind force, which is very helpful for quickly drying hair or performing specific hairstyles. Of course, when the user does not need to use the nozzle assembly, he can remove it at any time to slow down the air output speed. The existence of the nozzle assembly meets the needs of customers with different needs and improves the user's satisfaction with the hair dryer.

[0009] In one embodiment, the front shell assembly includes an outer shell, an inner shell, and a back cover. The inner shell is arranged on the outer shell, and the back cover is arranged on the inner shell. The inner shell and the back cover enclose the heating chamber, and the back cover is provided with an air guide channel. By arranging the inner shell on the outer shell and the back cover on the inner shell, the combined design of the outer shell and the inner shell provides dual protection and support for the hair dryer. The inner shell can withstand the weight of internal components such as the heating element and circuit board, as well as the vibration generated during operation, while the outer shell further enhances the overall structural stability. By arranging the inner shell on the outer shell, the two cooperate with each other, effectively preventing the hair dryer from being deformed or damaged by external forces during use. Furthermore, the cooperation between the inner shell and the back cover provides precise installation position and fixed support for the internal components of the hair dryer, ensuring that key components such as the heating element are accurately positioned inside the hair dryer, and preventing the performance and safety of the hair dryer from being affected by component displacement. The inner shell and back cover form a heating chamber that isolates the heating element from the rest of the hair dryer, providing a degree of safety protection. On the one hand, it prevents users from coming into direct contact with the high-temperature heating element during use, thus avoiding burns. On the other hand, the heating chamber also secures and protects the heating element, reducing the risk of damage due to collisions, vibrations, and other factors. An air guide channel is provided in the back cover to guide the airflow entering the hair dryer, directing it along a specific path. This ensures that the airflow effectively flows through the heating element, thereby improving heating efficiency.

[0010] In one embodiment, the back cover includes a support column and an air guide, wherein the support column is arranged on the air guide, which is arranged on the inner shell, and the air guide is provided with the air guide channel. By arranging the support column on the air guide and the air guide on the inner shell, the support column provides additional structural support for the air guide, making it more sturdy and durable. The connection between the air guide and the inner shell further enhances the stability of the overall structure of the hair dryer. This connection method can make the combination between the air guide and the inner shell tighter, reducing vibration and shaking during use, which not only helps to improve the performance and reliability of the hair dryer, but also prolong its service life. Providing an air guide channel in the air guide can, on the one hand, ensure that the air flow can effectively flow through the heating component, thereby improving the heating efficiency. On the other hand, the air guide channel can also serve as a protection against overheating. When the temperature inside the hair dryer is too high, the air guide channel can quickly discharge the hot air to prevent the internal temperature from continuing to rise, thereby protecting the internal components of the hair dryer from damage.

[0011] In one embodiment, a retaining ring is further provided, which is clamped between the outer shell and the inner shell. By clamping the retaining ring on the outer shell and the inner shell, the outer shell and the inner shell are fixedly connected, preventing the inner shell from shaking or moving within the outer shell. This helps maintain the stability of the hair dryer's overall structure and prevents the normal operation of internal components due to the loose inner shell.

[0012] In one embodiment, the heating assembly includes a positioning sleeve, a fixing ring, and a heating element. The positioning sleeve is disposed on the housing assembly, and the fixing ring is disposed on the positioning sleeve. There are multiple heating elements, multiple of which are disposed around the positioning sleeve and the fixing ring, and multiple of which are located in the heating chamber. By disposing the positioning sleeve on the housing assembly and the fixing ring on the positioning sleeve, a clear mounting position is provided for the fixing ring, allowing it to remain stable within the housing assembly. During operation of the hair dryer, the motor generates vibrations, and if the heating assembly is not properly secured, it may shift, affecting the heating effect and safety. The positioning sleeve effectively prevents the fixing ring from shaking, ensuring that it is always in the correct position. Disposing multiple heating elements around the positioning sleeve and the fixing ring and located in the heating chamber greatly increases the total heating area, thereby generating more heat per unit time, thereby improving the heating efficiency of the hair dryer. When air flows through these heating elements, it can be heated to the desired temperature more quickly, shortening the time required to dry hair or perform other heating operations. At the same time, the distribution of multiple heating elements can make the air more evenly heated when it flows through. The heating elements in different positions can heat the air at multiple angles, avoiding local overheating or uneven heating. In addition, the heating cavity prevents heat loss, ensuring that the temperature of the hot air blown out is uniform, reducing heat damage to hair or other objects, and improving the consistency of the heating effect.

[0013] In one embodiment, the installation cavity is divided into the heating cavity and the blowing cavity which are connected in sequence, the air inlet, the air supply cavity, the heating cavity, the blowing cavity and the air outlet are connected in sequence, and the heating component is located in the heating cavity. By dividing the installation cavity into the heating cavity and the blowing cavity, when a device fails, it is easier to determine the area where the problem is located, thereby improving the efficiency of troubleshooting and reducing the difficulty of maintenance. Since the air inlet, the air supply cavity, the heating cavity, the blowing cavity and the air outlet are connected in sequence to form a continuous airflow channel, this channel provides a clear path for the flow of air, ensuring the smooth flow of airflow. At the same time, the heating component is located in the heating cavity, which can achieve centralized heating of the air and can heat the air to the required temperature more quickly to meet the user's usage needs.

[0014] In one embodiment, the handle assembly includes a handle housing and an air inlet sleeve, the handle housing is arranged on the housing assembly, the fan assembly is arranged on the handle housing, the extension direction of the handle housing and the extension direction of the air outlet direction of the housing assembly form the acute angle, the handle housing is provided with the air supply cavity, the air inlet sleeve is arranged on the handle housing, the air inlet sleeve is provided with the air inlet holes, the number of the air inlet holes is multiple, and the multiple air inlet holes are arranged around the air inlet sleeve. By arranging the handle housing on the housing assembly, the connection between the handle housing and the housing assembly can provide additional structural support for the hair dryer and enhance the overall stability. The fan assembly can be accommodated inside the handle housing. By arranging the handle housing on the housing assembly, these internal components can be fixed in a relatively stable position to prevent them from loosening or shifting during use. This helps to ensure the normal operation and safety of the hair dryer. Because the handle housing and the housing assembly are arranged at a certain angle, the user can hold the hair dryer more comfortably, reducing fatigue during use. At the same time, when the airflow passes through the air supply cavity of the handle housing and enters the heating cavity, it is more evenly distributed to the heating element, and when the airflow flows out of the blowing cavity, the temperature uniformity is improved. Because the air inlet sleeve is arranged on the handle housing and is provided with multiple air inlet holes, the provision of multiple air inlet holes greatly increases the air inlet area, which can ensure that sufficient and uniform air can enter the air supply cavity when the hair dryer is working. The uniform and sufficient air intake helps ensure that the heating assembly heats the air more evenly, thereby making the temperature of the blown hot air more stable and reducing damage to the hair caused by local overheating.

[0015] In one embodiment, the handle housing includes a handle inner shell and a handle outer shell, both of which are arranged on the housing assembly, the handle inner shell is arranged on the inner side of the handle outer shell, and the blower assembly is arranged on the handle inner shell. By arranging the handle inner shell on the inner side of the handle outer shell and arranging the handle inner shell and the handle outer shell on the housing assembly at the same time, this design can significantly enhance the overall strength of the handle housing. The handle assembly will be subjected to various external forces during use, such as gripping force, torque, etc. The handle inner shell provides internal support, and the handle outer shell provides external protection. The combined effect of the two enables the handle assembly to better resist these external forces and reduce the risk of deformation and damage. Arranging the blower assembly on the handle inner shell can make the weight of the hair dryer more evenly distributed throughout the product. In this way, the user will feel more balanced when holding the hair dryer during use, reducing hand fatigue.

[0016] In one embodiment, the hair dryer further includes a control assembly, comprising a control button and a control element. The control button is disposed on the control element, which is disposed on the inner handle housing. The handle housing is provided with a button receiving hole, and the control button is disposed on the handle housing and located at the button receiving hole. By disposing the control button on the control element and in the button receiving hole of the handle housing, the user can conveniently locate and operate all major control functions within a specific area, eliminating the need to search for scattered buttons in different parts of the hair dryer. This improves the convenience and efficiency of operation. All control options can be clearly seen at a glance, and the function of each button can be quickly understood based on the identification and layout of the control buttons, reducing the possibility of operational errors. By disposing the control element on the inner handle housing and rationally arranging the control element within the inner handle housing, the internal structure of the hair dryer can be made more orderly, reducing the entanglement and confusion of wires and improving the reliability and stability of the product.

[0017] In one embodiment, the housing assembly further includes a circuit board assembly, wherein the housing assembly is provided with a receiving cavity, and the circuit board assembly is disposed on the housing assembly and located within the receiving cavity. By disposing the circuit board assembly on the housing assembly and within the receiving cavity, a relatively enclosed space is provided for the circuit board assembly, effectively protecting the circuit board assembly from external physical factors. Furthermore, the space within the hair dryer can be better utilized, achieving a more rational layout. This makes the overall structure of the hair dryer more compact, improves the appearance of the hair dryer, and enhances its market competitiveness. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0036] The hair dryers according to some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0037] Example

[0038] like Figures 1 to 9As shown, this embodiment discloses an electric hair dryer, comprising: a shell assembly 1, the shell assembly 1 is provided with a mounting cavity, and the shell assembly 1 is provided with an air outlet 101 connected to the mounting cavity; a heating assembly 2, the heating assembly 2 is arranged on the shell assembly 1 and located in the mounting cavity; a handle assembly 3, the handle assembly 3 is arranged on the shell assembly 1, the handle assembly 3 is provided with an air supply cavity 301 and an air inlet hole 302, the angle formed by the fluid flow direction in the air supply cavity 301 and the blowing direction of the air outlet 101 of the shell assembly 1 is an acute angle A, and the air inlet hole 302, the air supply cavity 301, the mounting cavity and the air outlet 101 are connected in sequence; a fan assembly 4, the fan assembly 4 is arranged on the handle assembly 3 and located in the air supply cavity 301.

[0039] The present application discloses a hair dryer in which a heating assembly 2 is disposed within a housing assembly 1 and located within a mounting cavity. This provides physical protection for the heating assembly 2, preventing damage to the heating assembly 2 from external impacts or extrusion. During daily use, if the hair dryer is accidentally bumped or dropped, the housing assembly 1 provides a cushion for the internal heating assembly 2, reducing the risk of damage. The housing assembly 1 also isolates the heating assembly 2 from the user, preventing the user from directly contacting the high-temperature heating assembly 2 and potentially causing burns. This provides an important safety measure for users, especially those with children in a home environment. A handle assembly 3 is disposed on the housing assembly 1, and the direction of fluid flow within the handle assembly 3 forms an acute angle A with the direction of air flow from the housing assembly 1. Optionally, the acute angle A ranges from 90° > A > 45°. Preferably, the acute angle A in this application is 87°. The tilted handle assembly 3 better conforms to the natural drooping angle of the human hand, making it more comfortable for the user to hold the hair dryer. When the user holds the hair dryer with the tilted handle assembly 3, the wrist can be in a relatively natural state, reducing fatigue and discomfort caused by long-term use, allowing the wrist to be more relaxed, and improving the comfort of use. At the same time, the tilted handle makes the operation of the hair dryer more convenient, and the user can more easily adjust the angle and direction of the hair dryer to better dry different parts of the hair. Furthermore, if the angle between the handle assembly 3 and the shell assembly 1 is set to be a right angle, when the airflow flows through the handle assembly 3 and then enters the heating assembly 2, there is an extremely uneven diversion phenomenon when the airflow flows through the end face of the heating assembly 2, that is, the air intake volume is large when the heating body is away from the handle end, and the air intake volume is small when it is close to the handle end, resulting in uneven air outlet temperature. Therefore, when the acute angle A formed by the air supply direction of the center line of the handle assembly 3 and the air outlet direction of the center line of the shell assembly 1 is less than 87°, the fan assembly 4 drives the external airflow to enter from the air inlet 302 and pass through the air supply cavity 301, so that the airflow can flow through the handle assembly 3 and then enter the installation cavity and be more evenly distributed in the heating assembly 2 for heating, so that the temperature uniformity of the airflow is better when it is blown out from the air outlet 101, which greatly improves the user experience and makes the hair dryer have greater market competitiveness.

[0040] like Figure 2 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the angle formed by the length direction of the handle assembly 3 and the length direction of the shell assembly 1 is an acute angle A. By setting the angle formed by the handle assembly 3 and the shell assembly 1 to be an acute angle A, it is beneficial for the airflow to flow through the handle assembly 3 and enter the installation cavity and be more evenly distributed in the heating assembly 2 for heating, so that the temperature uniformity of the airflow when blown out from the air outlet 101 is better, and the handle assembly 3 is more closely fitted to the natural curve of the hand when held. When people hold the hair dryer, their palms and fingers can more comfortably wrap around the handle, reducing hand fatigue.

[0041] like Figure 1 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines: the shell assembly 1 includes a nozzle assembly 11, a front shell assembly 12 and a rear shell assembly 13, the nozzle assembly 11 is arranged on the front shell assembly 12, the rear shell assembly 13 is arranged on the front shell assembly 12, the nozzle assembly 11 is provided with a blowing cavity 103, the front shell assembly 12 is provided with a heating cavity 102, and the heating cavity 102 and the blowing cavity 103 are connected in sequence to form an installation cavity. The basic structure of the housing assembly 1 is formed by placing the nozzle assembly 11 on the front shell assembly 12 and the rear cover assembly 13 on the front shell assembly 12. The blowing chamber 103 provided in the nozzle assembly 11 can directional guide the air blown by the hair dryer, so that the air is blown more concentratedly to a specific area. When styling, the nozzle assembly 11 can be aimed at the part of the hair that needs to be dried or shaped, ensuring that the hot air can accurately act on the target area, improving the styling effect and efficiency. In addition, the nozzle assembly 11 installed at the front can protect the user from direct burns from the hot air to a certain extent. The presence of the nozzle assembly 11 increases the distance from the heating element, reducing the risk of accidental contact with high-temperature airflow. At the same time, placing the nozzle assembly 11 on the front shell assembly 12 makes it easy for users to replace different types of nozzles according to different needs. Users can easily install or remove nozzles with different functions according to their hairstyle, styling needs, and usage scenarios, achieving a personalized user experience. The rear cover assembly 13 is combined with the front shell assembly 12 to form an enclosed space, which protects the hair dryer's internal components, such as the heating element and circuit board, and prevents external factors such as dust and moisture from entering the hair dryer, which could affect its normal operation and service life. A heating chamber 102 is provided in the front shell assembly 12, providing a specific space for the hair dryer's heating element 2. This allows the air to be heated more evenly as it flows through the heating element 2, while also allowing heat to be generated and transferred to the blowing chamber 103 in a more concentrated manner. This combination of mounting chambers can shorten the time it takes for the hair dryer to reach the set temperature, improve blowing efficiency, and allow users to complete tasks such as drying or styling their hair more quickly.

[0042] like Figure 3 and Figure 4As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the nozzle assembly 11 includes a nozzle 111 and a connector 112, the nozzle 111 is arranged on the connector 112, the connector 112 is arranged on the front shell assembly 12, and the nozzle 111 and the connector 112 enclose to form a blowing chamber 103. By arranging the nozzle 111 on the connector 112 and the connector 112 on the front shell assembly 12, firstly, the connector 112 provides a stable support and fixing structure for the nozzle 111. Compared with directly installing the nozzle 111 on the front shell assembly 12, adding the connector 112 can make the installation of the nozzle 111 more secure and reliable, able to withstand various external forces that may be encountered during use, reduce the risk of the nozzle 111 loosening, shifting or even falling off, and ensure that the nozzle 111 always remains in the correct position during use, thereby ensuring the stability of the blowing effect. The nozzle 111 and the connector 112 together form a blowing chamber 103. The blowing chamber 103 can concentrate the airflow generated by the hair dryer into a relatively small space, making the airflow more concentrated and powerful, allowing the airflow to be blown out in a more targeted manner, and reducing the diffusion and scattering of the airflow. When the airflow passes through the blowing chamber 103, due to the limited space, the airflow speed increases, thereby enhancing the wind force. This is very helpful for quickly drying hair or performing specific hairstyles. Of course, when the user does not need to use the nozzle assembly 11, it can be removed at any time to slow down the airflow speed. The existence of the nozzle assembly 11 meets the needs of customers with different needs and improves user satisfaction with the hair dryer.

[0043] like Figure 3 and Figure 5As shown, in addition to the features of the above-described embodiment, this embodiment further defines that the front housing assembly 12 includes an outer housing 121, an inner housing 122, and a rear cover 123. The inner housing 122 is disposed on the outer housing 121, and the rear cover 123 is disposed on the inner housing 122. The inner housing 122 and the rear cover 123 enclose a heating chamber 102, and the rear cover 123 is provided with an air guide channel 104. By disposing the inner housing 122 on the outer housing 121 and the rear cover 123 on the inner housing 122, the combination of the outer housing 121 and the inner housing 122 provides dual protection and support for the hair dryer. The inner housing 122 can withstand the weight of internal components such as the heating assembly 2 and circuit board, as well as vibrations generated during operation, while the outer housing 121 further enhances the overall structural stability. By disposing the inner housing 122 on the outer housing 121, the two housings cooperate to effectively prevent deformation or damage to the hair dryer due to external forces during use. Furthermore, the cooperation between the inner shell 122 and the back cover 123 provides a precise installation position and fixed support for the internal components of the hair dryer, which can ensure that the key components such as the heating component 2 are accurately positioned inside the hair dryer, and avoid affecting the performance and safety of the hair dryer due to component displacement. Since the inner shell 122 and the back cover 123 enclose and form a heating chamber 102, the heating chamber 102 isolates the heating component 2 from other parts of the hair dryer, playing a certain safety protection role. On the one hand, it can prevent the user from directly contacting the high-temperature heating component during use, avoiding the occurrence of scalding accidents. On the other hand, the heating chamber 102 can also play a certain fixing and protective role for the heating component 2, reducing the risk of damage to the heating component due to factors such as collision and vibration. The air guide channel 104 is set on the back cover 123, which can guide the airflow entering the interior of the hair dryer so that it flows along a specific path, thereby ensuring that the airflow can effectively flow through the heating component 2, thereby improving the heating efficiency.

[0044] like Figure 5 and Figure 6As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that the back cover 123 includes a support column 1231 and an air guide 1232, wherein the support column 1231 is arranged on the air guide 1232, and the air guide 1232 is arranged on the inner shell 122, and the air guide 1232 is provided with an air guide channel 104. By arranging the support column 1231 on the air guide 1232 and arranging the air guide 1232 on the inner shell 122, the support column 1231 provides additional structural support for the air guide 1232, making it more sturdy and durable. The connection between the air guide 1232 and the inner shell 122 further enhances the stability of the overall structure of the hair dryer. This connection method can make the combination between the air guide 1232 and the inner shell 122 tighter, reduce vibration and shaking during use, which not only helps to improve the performance and reliability of the hair dryer, but also prolong its service life. An air guide channel 104 is provided in the air guide member 1232. On the one hand, it can ensure that the air flow can effectively flow through the heating component 2, thereby improving the heating efficiency. On the other hand, the air guide channel 104 can also play a role in preventing overheating. When the internal temperature of the hair dryer is too high, the air guide channel 104 can quickly discharge the hot air to prevent the internal temperature from continuing to rise, thereby protecting the internal components of the hair dryer from damage.

[0045] like Figure 5 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further comprises a retaining ring 124, which is positioned between the outer shell 121 and the inner shell 122. By retaining the retaining ring 124 between the outer shell 121 and the inner shell 122, the outer shell 121 and the inner shell 122 are fixedly connected, preventing the inner shell 122 from shaking or moving within the outer shell 121. This helps maintain the stability of the hair dryer's overall structure and prevents the normal operation of internal components from being affected by loosening of the inner shell 122.

[0046] like Figure 3 and Figure 7As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the heating component 2 includes a positioning sleeve 21, a fixing ring 22 and a heating element 23, the positioning sleeve 21 is arranged on the shell assembly 1, the fixing ring 22 is arranged on the positioning sleeve 21, the number of the heating element 23 is multiple, and the multiple heating elements 23 are arranged around the positioning sleeve 21 and the fixing ring 22, and the multiple heating elements 23 are located in the heating chamber 102. By setting the positioning sleeve 21 on the shell assembly 1 and setting the fixing ring 22 on the positioning sleeve 21, a clear installation position is provided for the fixing ring 22, so that it remains stable in the shell assembly 1. During the operation of the hair dryer, the motor will vibrate when it runs. If the heating component 2 is not fixed properly, it may be displaced, affecting the heating effect and safety. The positioning sleeve 21 can effectively prevent the fixing ring 22 from shaking, ensuring that it is always in the correct position. Multiple heating elements 23 are arranged around the positioning sleeve 21 and the fixing ring 22 and are located in the heating chamber 102. First, the multiple heating elements 23 can greatly increase the total heating area, thereby generating more heat per unit time, thereby improving the heating efficiency of the hair dryer. When air flows through these heating elements 23, it can be heated to the desired temperature more quickly, shortening the time for drying hair or performing other heating operations. At the same time, the distribution of the multiple heating elements 23 can ensure more uniform heating of the air as it flows through. The heating elements 23 in different positions can heat the air from multiple angles, avoiding local overheating or uneven heating. In addition, the heating chamber 102 prevents heat loss, ensuring that the temperature of the blown hot air is uniform, reducing heat damage to hair or other objects, and also improving the consistency of the heating effect.

[0047] like Figure 3 and Figure 4 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the installation cavity is divided into a heating cavity 102 and a blowing cavity 103 which are connected in sequence, the air inlet 302, the air supply cavity 301, the heating cavity 102, the blowing cavity 103 and the air outlet 101 are connected in sequence, and the heating component 2 is located in the heating cavity 102. By dividing the installation cavity into the heating cavity 102 and the blowing cavity 103, when a fault occurs in the equipment, it is easier to determine the area where the problem is located, thereby improving the efficiency of troubleshooting and reducing the difficulty of maintenance. Since the air inlet 302, the air supply cavity 301, the heating cavity 102, the blowing cavity 103 and the air outlet 101 are connected in sequence to form a continuous airflow channel, this channel provides a clear path for the flow of air, ensuring the smooth circulation of the airflow. At the same time, the heating component 2 is located in the heating cavity 102, which can achieve centralized heating of the air and can heat the air to the required temperature more quickly to meet the user's usage needs.

[0048] like Figure 3 、 Figure 8 and Figure 9As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines: the handle assembly 3 includes a handle housing 31 and an air inlet sleeve 32. The handle housing 31 is mounted on the housing assembly 1, and the fan assembly 4 is mounted on the handle housing 31. The extension direction of the handle housing 31 forms an acute angle A with the extension direction of the air outlet of the housing assembly 1. The handle housing 31 defines an air supply cavity 301. The air inlet sleeve 32 is mounted on the handle housing 31 and defines a plurality of air inlet holes 302, which are arranged around the air inlet sleeve 32. By mounting the handle housing 31 on the housing assembly 1, the connection between the handle housing 31 and the housing assembly 1 provides additional structural support for the hair dryer, enhancing overall stability. The handle housing 31 can accommodate the fan assembly 4. By mounting the handle housing 31 on the housing assembly 1, these internal components are secured in a relatively stable position, preventing them from loosening or shifting during use. This helps ensure the proper operation and safety of the hair dryer. Because the handle housing 31 and the housing assembly 1 are arranged at a certain angle, the user can hold the hair dryer more comfortably, reducing fatigue during use. At the same time, when the airflow passes through the air supply cavity 301 of the handle housing 31 and enters the heating cavity 102, it is more evenly distributed to the heating element 23. When the airflow flows out of the blowing cavity 103, the temperature uniformity is improved. Since the air inlet sleeve 32 is arranged on the handle housing 31 and multiple air inlet holes 302 are provided on the air inlet sleeve 32, the provision of multiple air inlet holes 302 greatly increases the air inlet area, which can ensure that sufficient and uniform air can enter the air supply cavity 301 when the hair dryer is working. The uniform and sufficient air intake helps to ensure that the heating assembly 2 heats the air more evenly, thereby making the temperature of the blown hot air more stable and reducing damage to the hair caused by local overheating.

[0049] like Figure 3 and Figure 8As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines: the handle housing 31 includes a handle inner shell 311 and a handle outer shell 312. Both the handle inner shell 311 and the handle outer shell 312 are disposed on the housing assembly 1, with the handle inner shell 311 disposed inside the handle outer shell 312, and the blower assembly 4 disposed on the handle inner shell 311. By disposing the handle inner shell 311 inside the handle outer shell 312, and simultaneously disposing the handle inner shell 311 and the handle outer shell 312 on the housing assembly 1, this design significantly enhances the overall strength of the handle housing 31. During use, the handle assembly 3 is subjected to various external forces, such as gripping force and torque. The handle inner shell 311 provides internal support, while the handle outer shell 312 provides external protection. The combined effect of the two enables the handle assembly 3 to better withstand these external forces, reducing the risk of deformation and damage. Placing the blower assembly 4 on the handle inner shell 311 more evenly distributes the weight of the hair dryer throughout the entire product. This provides a more balanced feel when the user holds the hair dryer, reducing hand fatigue.

[0050] like Figure 8 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines: it also includes a control assembly 5, which includes a control button 51 and a control element 52. The control button 51 is disposed on the control element 52, which is disposed on the handle inner shell 311. The handle outer shell 312 is provided with a button receiving hole 303. The control button 51 is disposed on the handle outer shell 312 and located at the button receiving hole 303. By arranging the control button 51 on the control element 52 and arranging the control button 51 at the button receiving hole 303 of the handle outer shell 312, the user can conveniently find and operate all major control functions in a single area, eliminating the need to search for scattered buttons in different parts of the hair dryer. This improves the convenience and efficiency of operation. At the same time, all control options can be clearly seen at a glance, and the function of each button can be quickly understood based on the labeling and layout of the control button 51, reducing the possibility of operational errors. By arranging the control element 52 on the handle inner shell 311 and by rationally arranging the control element 52 within the handle inner shell 311, the internal structure of the hair dryer is more orderly, reducing the entanglement and confusion of wires, and improving the reliability and stability of the product.

[0051] like Figure 3As shown, in addition to the features of the above-mentioned embodiment, this embodiment is further defined as follows: further comprising a circuit board assembly 6, a housing assembly 1 having a receiving cavity 105, and the circuit board assembly 6 being disposed on the housing assembly 1 and located within the receiving cavity 105. By disposing the circuit board assembly 6 on the housing assembly 1 and within the receiving cavity 105, a relatively enclosed space is provided for the circuit board assembly 6, effectively protecting the circuit board assembly 6 from external physical factors. At the same time, the space inside the hair dryer can be better utilized to achieve a more reasonable layout, thereby making the overall structure of the hair dryer more compact, improving the appearance of the hair dryer, and enhancing its market competitiveness.
