[0002] Traditional hair dryers typically consist of a housing and a nozzle connector. The nozzle connector is detachably attached to the air outlet of the housing. By using different types of nozzle connectors, the housing can deliver precise airflow to meet users' personalized hair styling needs. Furthermore, to reduce hand fatigue caused by prolonged use of the hair dryer, the housing is usually made of plastic to reduce weight.
[0003] However, the problem with the aforementioned structure is that, due to the frequent replacement of the nozzle connector, the plastic connection at the air outlet of the plastic casing is prone to wear. This leads to noticeable loosening of the nozzle connector after installation, resulting in decreased stability of the connection between the casing and the nozzle connector, affecting the user experience, or even causing the casing connection structure to fail completely. Therefore, there is an urgent need to develop a new type of hair dryer that can maintain the lightweight advantage of the hair dryer while significantly improving the durability and stability of the connection points at the casing. Utility Model Content
[0004] The technical problem to be solved by this utility model embodiment is to provide a hair dryer to solve the problem in the prior art where the casing of the hair dryer is easily worn when the nozzle connector is frequently replaced, resulting in a decrease in the structural connection stability.
[0005] The hair dryer provided in this embodiment of the utility model includes:
[0006] The housing has an air outlet and is made of plastic.
[0007] The first connecting seat is installed at the air outlet;
[0008] A nozzle connector is connected to the housing via the first connecting seat. The nozzle connector is used to change the direction of the airflow from the air outlet.

[0011] In one embodiment, the first connecting seat includes a mounting sleeve, which is fitted onto the air outlet. The first connecting structure is a groove disposed on the mounting sleeve, and the second connecting structure is a buckle disposed on the wall of the air outlet. The groove is fastened to the buckle.
[0012] In one embodiment, multiple slots and multiple buckles are provided, with the multiple buckles arranged around the opening wall of the air outlet, and the positions of the multiple slots and the multiple buckles corresponding one-to-one.
[0013] In one embodiment, the mounting sleeve includes a peripheral wall surrounding the inlet wall of the air outlet, the slot is disposed on the peripheral wall, the peripheral wall is also provided with a limiting groove, the inlet wall of the air outlet is also provided with a limiting protrusion, the limiting groove passes through one side of the mounting sleeve to form a through-hole for the limiting protrusion to be inserted, and the limiting protrusion is received in the limiting groove through the through-hole.
[0014] In one embodiment, the first connecting seat further includes a guide sleeve surrounding the mounting sleeve, the guide sleeve being connected to the mounting sleeve and located outside the housing, and the nozzle connector being mounted on the guide sleeve; the guide sleeve is configured to gradually narrow or expand in the air outlet direction.
[0015] In one embodiment, the inner wall of the guide sleeve is provided with an internal thread, and the nozzle connector includes a hollow threaded post, which is threadedly connected to the internal thread.
[0016] In one embodiment, the housing is further provided with an air inlet, which is arranged opposite to the air outlet; the hair dryer also includes a second connecting seat, which is installed at the air inlet.

[0018] The hair dryer also includes a honeycomb sheet, which is installed inside the air inlet. When the second connecting seat is installed in the air inlet, the crimping flange abuts against the honeycomb sheet.
[0019] In one embodiment, the system further includes a continuously variable speed control assembly and a high-speed fan. The high-speed fan is installed inside the housing. The continuously variable speed control assembly includes a roller and a control board. The roller is rotatably connected to the housing and partially exposed outside the housing. The roller is electrically connected to the high-speed fan through the control board. Rotating the roller is used to control the airflow speed of the high-speed fan.
[0020] Compared with the prior art, the hair dryer provided by this utility model has the following advantages: the hair dryer of this application can ensure the connection stability of the nozzle connector even when the user frequently switches the nozzle connector, and can effectively reduce the wear at the installation connection, thus making it more reliable.
[0021] Specifically, the hair dryer has an additional first connector at the air outlet of its plastic casing. The nozzle connector is connected to the casing through the first connector.

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0045] This utility model embodiment provides a hair dryer 1000, such as Figure 1 - Figure 4As shown, the hair dryer 1000 includes a housing 10, a first connecting seat 20, and a nozzle connector 30. The housing 10 has an air outlet 11 and is made of plastic. The first connecting seat 20 is installed at the air outlet 11. The nozzle connector 30 is connected to the housing 10 via the first connecting seat 20 and is used to change the airflow direction from the air outlet 11. The first connecting seat 20 is made of metal. This application solves the problem in the prior art where frequent disassembly and installation of the plastic housing 10 with different types of nozzle connectors 30 leads to wear at the connection points, resulting in decreased connection stability. Even during frequent switching of the nozzle connector 30 by the user, the hair dryer 1000 can maintain the connection stability of the nozzle connector 30 and effectively reduce wear at the installation connection points, thus improving reliability.
[0046] Specifically, the hair dryer 1000 adds a first connecting seat 20 to the air outlet 11 at its plastic housing 10. The nozzle connector 30 is connected to the housing 10 through the first connecting seat 20. Since the first connecting seat 20 is made of metal, compared with the embodiment where the nozzle connector 30 is directly installed to the plastic housing 10, the metal first connecting seat 20 has better structural strength and can more effectively resist the wear caused by repeated disassembly and assembly of the nozzle connector 30. This improves the connection stability of the nozzle connector 30, reduces the loosening of the nozzle connector 30, makes the overall structural reliability of the hair dryer 1000 better, and effectively extends the service life of the housing 10.
[0047] It is worth mentioning that by implementing the above solution, since the housing 10 is still made of plastic, compared with the embodiment where the housing 10 is made of metal, by only setting the first connecting seat 20, it can improve the connection stability of the nozzle connector 30 and keep the hair dryer 1000 at a lighter weight for easy carrying and use by users, thus achieving the best balance between product strength and weight. The hair dryer 1000 takes into account both lightness and portability and practicality.
[0048] Furthermore, without the first connector 20 (i.e., the nozzle connector 30 is directly connected to the housing 10), the following problems may arise: First, maintenance costs would be too high. Disassembling the nozzle connector 30 could easily cause structural damage to the plastic housing 10 (such as stripped threads or cracked housing), requiring the replacement of the entire housing 10 instead of just repairing the nozzle connector 30, significantly increasing costs. Second, the housing 10 would be difficult to repair; it is usually difficult to repair locally after direct damage, forcing users to replace the hair dryer, creating an additional financial burden. Therefore, the first connector 20 also reduces the risk of wear and tear on the housing 10 due to frequent maintenance.
[0049] In this application, the housing 10 includes a mounting part 13 and a gripping part 14, which are arranged vertically. The air outlet 11 is located at the mounting part 13, and the gripping part 14 is used for the user to hold during use. The mounting part 13 and the gripping part 14 together define the installation space inside the housing 10, which can be used to install other components of the hair dryer 1000.
[0050] It is understandable that, while ensuring a relatively light weight, those skilled in the art can adjust the configuration of the casing 10 according to various design requirements such as aesthetics, and no limitations are imposed here.
[0051] The metal material of the first connecting seat 20 can be aluminum, stainless steel, etc. There is no limitation on the type of material. Those skilled in the art can make adjustments according to design requirements.
[0052] It should be noted that there are many types of nozzle connectors 30. They can be diffuser nozzles 30 for volumizing hair, wide-tooth comb nozzles 30 for straightening curly hair, or anti-splitting nozzles 30 for straightening flyaway hair. No limitation is made on the configuration of the nozzle connector 30. Users can choose the appropriate nozzle connector 30 based on their actual hair drying requirements. This hair dryer 1000 has greater compatibility and can provide users with a more comprehensive user experience.
[0053] In this application, the first connecting seat 20 is provided with a first connecting structure 211, and the outlet wall of the air outlet 11 is provided with a second connecting structure 111. The second connecting structure 111 is connected to the first connecting structure 211 to limit the installation of the first connecting seat 20 at the air outlet 11. There are many ways to arrange the first connecting structure 211 and the second connecting structure 111.
[0054] Reference Figure 6 - Figure 9In one embodiment, the first connecting seat 20 includes a mounting sleeve 21, which is fitted onto the air outlet 11. The first connecting structure 211 is a groove 2111 on the mounting sleeve 21, and the second connecting structure 111 is a buckle 1111 on the wall of the air outlet 11. The groove 2111 is engaged with the buckle 1111. This configuration achieves two advantages: First, the groove 2111 engages with the buckle 1111, ensuring a stable connection between the first connecting seat 20 and the housing 10. Second, by fitting the groove 2111 onto the mounting sleeve 21 and using the mounting sleeve 21 fitted onto the air outlet 11, the mounting sleeve 21 can cooperate with the wall of the air outlet 11, thereby positioning the first connecting seat 20 and making assembly faster and more efficient. Preferably, multiple slots 2111 and multiple buckles 1111 are provided, with the multiple buckles 1111 arranged around the wall of the air outlet 11, and the positions of the multiple slots 2111 and the multiple buckles 1111 corresponding one-to-one. In this way, the multiple slots 2111 and multiple buckles 1111 can make the force more balanced when the first connecting seat 20 is connected, thereby further improving the connection stability between the first connecting seat 20 and the housing 10. For example, in this application, four slots 2111 and four buckles 1111 are provided, and the four buckles 1111 are arranged circumferentially at equal intervals along the wall of the outlet.
[0055] In another embodiment, the first connecting seat 20 includes a mounting sleeve 21, which is fitted onto the air outlet 11. The first connecting structure 211 is a first magnet (not shown in the figure) disposed on the mounting sleeve 21, and the second connecting structure 111 is a second magnet (not shown in the figure) disposed on the wall of the air outlet 11. The first magnet magnetically connects to the second magnet to achieve a stable connection between the first connecting seat 20 and the housing 10.
[0056] In another embodiment, the first connecting seat 20 includes a mounting sleeve 21, which is fitted onto the air outlet 11. The first connecting structure 211 is an external thread structure (not shown in the figure) provided on the mounting sleeve 21, and the second connecting structure 111 is an internal thread structure 221 (not shown in the figure) provided on the wall of the air outlet 11. The external thread structure is threadedly connected to the internal thread structure 221 to achieve a stable connection between the first connecting seat 20 and the housing 10.
[0057] Reference Figure 8 In one embodiment, the buckle 1111 is provided with a guide surface 1111a. The guide surface 1111a faces the air outlet 11 and is set at an angle to the air outlet 11. During the process of inserting the mounting sleeve 21 into the air outlet 11, the guide surface 1111a can first contact the outer peripheral surface of the mounting sleeve 21 to reduce the friction generated during the movement and effectively guide the buckle 1111 to slide into the slot 2111, making the assembly process smoother and without jamming.
[0058] Reference Figure 7 - Figure 9 In one embodiment, the mounting sleeve 21 includes a peripheral wall 212 surrounding the inlet wall of the air outlet 11, a slot 2111 is provided on the peripheral wall 212, a limiting groove 2121 is also provided at the peripheral wall 212, and a limiting protrusion 112 is also provided at the inlet wall of the air outlet 11. The limiting groove 2121 penetrates one side of the mounting sleeve 21 to form a through opening 2121a for the limiting protrusion 112 to be inserted. The limiting protrusion 112 is accommodated in the limiting groove 2121 through the through opening 2121a. With this configuration, during the installation process of inserting the mounting sleeve 21 into the air outlet 11, the limiting protrusion 112 can move relative to the through-hole 2121a and be accommodated in the limiting groove 2121, thereby restricting the rotation of the first connecting seat 20 relative to the air outlet 11 of the housing 10. This prevents the first connecting seat 20 from slightly rotating relative to the housing 10 due to the fit gap between the slot 2111 and the buckle 1111, further improving the stability of the connection. In addition, the limiting protrusion 112 can also restrict the installation direction of the first connecting seat 20, which has a foolproof function, avoiding the situation where the connection is not in place due to misoperation during the assembly process, and improving the accuracy of assembly.
[0059] Reference Figure 6 and Figure 9 In one embodiment, the first connecting seat 20 further includes a guide sleeve 22 surrounding the mounting sleeve 21. The guide sleeve 22 is connected to the mounting sleeve 21 and located outside the housing 10, and the nozzle connector 30 is mounted on the guide sleeve 22. The guide sleeve 22 is gradually narrowed or expanded in the air outlet 11 direction. With this configuration, the guide sleeve 22 allows the first connecting seat 20 to concentrate or expand the airflow from the air outlet 11, so as to better achieve the hair styling effect required by the user by matching different types of nozzle connectors 30.
[0060] In one embodiment, the inner wall of the guide sleeve 22 is provided with an internal thread 221, and the nozzle connector 30 includes a hollow threaded post 31, which is threadedly connected to the internal thread 221. This arrangement enables a quick-release connection between the nozzle connector 30 and the first connecting seat 20, and the cooperation between the internal thread 221 and the hollow threaded post 31 effectively reduces the gap between the nozzle connector 30 and the first connecting seat 20, preventing air leakage.
[0061] Reference Figure 6In one embodiment, the housing 10 is further provided with an air inlet 12, which is positioned opposite to the air outlet 11. The hair dryer 1000 also includes a second connector 40, which is installed at the air inlet 12. The second connector 40 is made of metal and is used to install another nozzle connector 30. This configuration, through the provision of the second connector 40, further meets the user's needs, giving the hair dryer 1000 more comprehensive hair drying functions.
[0062] To better understand the technical effects achieved by the above embodiments, specific application scenarios are illustrated below. When a user uses the hair dryer 1000 for hair styling, the user can attach the desired type of nozzle connector 30 to the first connecting seat 20 and the second connecting seat 40. During hair drying, the hair roots can be dried using the nozzle connector 30 on the first connecting seat 20. After drying, the hair roots can be lifted using the nozzle connector 30 on the second connecting seat 40, thus enabling the user's hair to achieve a more efficient, voluminous, and non-flat styling effect. Since the air inlet 12 can be connected to the nozzle connector 30 on the second connecting seat 40, the stability during hair suction is improved, enhancing the user experience.
[0063] Specifically, the air inlet 12 is located at the mounting part 13, and the air inlet 12 is positioned opposite to the air outlet 11.
[0064] Similarly, the second connector 40 is configured in the same way as the first connector 20, and the configuration of the second connector 40 will not be repeated here.
[0065] Reference Figure 5 In one embodiment, the second connecting seat 40 is hollow inside, and a pressing flange 41 is provided on the inner wall of the second connecting seat 40, and the pressing flange 41 is arranged around the second connecting seat 40. The hair dryer 1000 also includes a honeycomb sheet 50, which is installed in the air inlet 12. When the second connecting seat 40 is installed in the air inlet 12, the pressing flange 41 abuts against the honeycomb sheet 50. With this arrangement, firstly, the honeycomb sheet 50 can separate the air when air enters the air inlet 12 to reduce the generation of wind noise, so that the hair dryer 1000 can meet the requirement of quiet operation. Secondly, by cleverly setting the pressing flange 41 on the second connecting seat 40, the honeycomb sheet 50 is installed and limited, so that the second connecting seat 40 can also improve the connection stability of the internal components of the hair dryer 1000.
[0066] Reference Figure 4In one embodiment, the hair dryer 1000 further includes a continuously variable speed control assembly 60 and a high-speed fan 70. The high-speed fan 70 is installed inside the housing 10. The continuously variable speed control assembly 60 includes a roller 61 and a control board 62. The roller 61 is rotatably connected to the housing 10 and partially exposed outside the housing 10. The roller 61 is electrically connected to the high-speed fan 70 through the control board 62. Rotating the roller 61 controls the airflow speed of the high-speed fan 70. With this configuration, the user can adjust the airflow speed of the high-speed fan 70 by rolling the roller 61. The hair dryer 1000 has a multi-level continuously variable speed airflow function, making it more convenient for users to adjust the airflow speed and meeting the needs of different users for different airflow levels.
[0067] Specifically, the high-speed fan 70 is installed at the mounting part 13, and the stepless speed regulation component 60 is installed at the grip part 14, so that the user can control the wind speed of the high-speed fan 70 with both hands when holding the blower 1000, making the operation more convenient.
[0068] Reference Figure 4 In one embodiment, the hair dryer 1000 further includes a battery 90 and an interface 80. The battery 90 is installed inside the housing 10 and electrically connected to the interface 80 and the high-speed fan 70. The interface 80 is exposed at the housing 10. With this configuration, the user can charge the hair dryer 1000 through the interface 80. The hair dryer 1000 does not require a power connection to blow air, and its smaller size makes it easier to use and carry, thus improving its portability.
[0069] Specifically, both the battery 90 and the interface 80 are installed at the grip portion 14.
