[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0038] Referring to Figures 1-4, this application provides a hair dryer, including a base 8 and a hair dryer body 2. The base 8 is provided with a first plug-in structure. The hair dryer body 2 includes a hair dryer head 21 and a hair dryer handle 22. One end of the hair dryer handle 22 is connected to the hair dryer head 21, and the other end of the hair dryer handle 22 is provided with a second plug-in structure. The second plug-in structure engages with the first plug-in structure to allow the hair dryer handle 22 to stand upright on the base 8. With this design, when the user needs to use the hair dryer in handheld mode, the hair dryer body 2 can be detached from the base 8, and the user can hold the hair dryer handle 22 while using the hair dryer body 2. When the user needs to use the hair dryer in fixed mode, the hair dryer body 2 can be installed on the base 8, that is, the hair dryer can be fixed in place for use. This frees up the user's hands and solves the problem of hand fatigue from holding the hair dryer for a long time, thereby meeting different user needs and improving the user experience.

[0039] Furthermore, the base 8 includes a base plate 81 and a base platform 82. The base platform 82 is fixed on the base plate 81. A first insertion structure is provided on the base platform 82. The first insertion structure includes an insertion block 821 and an elastic limiting member 83. The insertion block 821 is provided on the base 8, and the elastic limiting member 83 is provided on the insertion block 821. The second insertion structure includes an insertion groove 221 and a limiting groove 222. The insertion groove 221 is provided on the bottom wall of the hair dryer handle 22, and the limiting groove 222 is provided on the side wall of the hair dryer handle 22 and communicates with the insertion groove 221. The insertion block 821 is inserted into the insertion groove 221, and the elastic limiting member 83 is engaged in the limiting groove 222. While the plug block 821 is plugged into the plug slot 221, the elastic limiting member 83 is engaged with the limiting slot 222, so that the plug block 821 can be detachably fixed in the plug slot 221, thereby realizing the detachable installation of the hair dryer body 2 and the base 8. The structure is simple and easy to disassemble and assemble.

[0040] Furthermore, the plug-in block 821 has a hollow structure, and the plug-in block 821 has a first clearance opening that extends into the hollow structure. The elastic limiting member 83 is located in the hollow structure of the plug-in block 821, and the elastic limiting member 83 has a protrusion 831 that extends out from the first clearance opening to engage with the limiting groove 222.

[0041] Furthermore, the hollow structure of the plug-in block 821 is provided with a first buckle 822, and the top of the elastic limiting member 83 is provided with a second buckle 832. The second buckle 832 is fastened to the first buckle 822 to detachably connect the elastic limiting member 83 to the plug-in block 821. The connection between the elastic limiting member 83 and the plug-in block 821 is a buckle connection, which is simple in structure and easy to install.

[0042] Furthermore, the base 8 also includes an elastic reset member 84, which is located within the hollow structure. A second clearance opening is provided on the area outside the insertion block 821 on the base 8. A pressing part 833 is provided at the bottom of the elastic limiting member 83. One end of the elastic reset member 84 abuts against the pressing part 833, and the other end abuts against the inner wall of the hollow structure. The pressing part 833 protrudes through the second clearance opening and is exposed on the base 8. The pressing part 833 is used to move the elastic limiting member 83 to disengage from the limiting groove 222 under the action of external force. When the user needs to remove the hair dryer body from the base 8, pressing the pressing part 833 can disengage the elastic limiting member 83 from the limiting groove 222, allowing the insertion block 821 to be removed from the insertion groove 221, thereby achieving the disassembly of the hair dryer body 2 from the base 8. When the external force on the pressing part 833 is removed, the pressing part 833 can reset to drive the elastic limiting member 83 to reset. Specifically, when the external force pressing part 833 presses, the elastic reset member 84 is compressed by the pressure. When the external force on the pressing part 833 is removed, the elastic reset member 84 extends under its own elastic force and drives the pressing part 833 to reset.

[0043] Furthermore, the plug-in block 821 is also provided with a guide groove 823, and the inner side wall of the plug-in groove 221 is also provided with a guide block 223, which is connected to the guide groove 823. The guide block 223 and the guide groove 823 cooperate to guide the hair dryer handle 22 to be plugged into the base 8, so that when the plug-in block 821 is plugged into the plug-in groove 221, the elastic limiting member 83 can be smoothly inserted into the limiting groove 222.

[0044] Further, referring to Figure 5, the blower head 21 houses a blower assembly 3, and the blower handle 22 houses an electronic control element 5 and a heat dissipation duct 4. The heat dissipation duct 4 connects the air inlet 31 and air outlet 32 ​​of the blower assembly 3 and passes through the electronic control element 5. Under the action of the blower assembly 3, the heat dissipation duct 4 generates air that exchanges heat with the electronic control element 5. By setting up a heat dissipation duct 4 that passes through the electronic control element 5, and by generating air that exchanges heat with the electronic control element 5 under the action of the blower assembly 3, the electronic control element 5 can fully exchange heat with the air in the heat dissipation duct 4, accelerating the heat dissipation of the electronic control element 5 and thus preventing the electronic control element 5 from overheating and burning out.

[0045] Furthermore, the heat dissipation duct 4 is provided with a first air outlet 41 and a second air outlet 42. The first air outlet 41 is located at the connection between the blower handle 22 and the blower head 21 and is connected to the air outlet 32 ​​of the blower assembly 3. The second air outlet 42 is located at the connection between the blower handle 22 and the blower head 21 and is connected to the air inlet 31 of the blower assembly 3. When the air velocity at the air outlet 32 ​​of the blower assembly 3 is slow and the air pressure is high, the air outlet 32 ​​of the blower assembly 3 generates a blowing force. The air blown out by the blower assembly 3 enters the heat dissipation duct from the first air outlet 41. The air in the heat dissipation duct carries away the heat of the electronic control component 5 and is discharged from the blower handle 22 from the second air outlet 42. The air discharged from the second air outlet 42 is drawn into the blower assembly 3 from the air inlet 31 of the blower assembly 3 and is finally blown into the external environment by the blower assembly 3.

[0046] The hair dryer handle 22 is connected to the area of ​​the hair dryer head 21 corresponding to the fan assembly 3. The first air outlet 41 is set close to the air outlet 32 ​​of the fan assembly 3, so that the blowing effect of the fan assembly 3 is better. The second air outlet 42 is set close to the air inlet 31 of the fan assembly 3, so that the air inlet 31 of the fan assembly 3 has a better exhaust effect on the heat dissipation channel.

[0047] Furthermore, referring to Figure 6, a third air vent 43 is also provided on the heat dissipation duct 4. The third air vent 43 is located on the blower handle 22 and is connected to the external environment. When the air velocity at the air outlet 32 ​​of the blower assembly 3 is relatively fast and the air pressure is relatively low, the air outlet 32 ​​of the blower assembly 3 generates suction. Under the action of the suction of the blower assembly 3, the air in the external environment enters the heat dissipation channel from the third air vent 43. The air in the heat dissipation channel carries away the heat of the electronic control component 5 and then enters the interior of the blower head 21 from the first air vent 41 near the air outlet 32 ​​of the blower assembly 3 and the second air vent 42 near the air inlet 31 of the blower assembly 3. The air discharged from the first air vent 41 near the air outlet 32 ​​of the blower assembly 3 is directly blown out to the external environment by the blower assembly 3. The air discharged from the second air vent 42 near the air inlet 31 of the blower assembly 3 is drawn into the blower assembly 3 from the air inlet 31 of the blower assembly 3 and is finally blown out to the external environment by the blower assembly 3.

[0048] Specifically, the hair dryer body 2 also includes a motor and a circuit board. The motor is located inside the hair dryer head 21 and directly above the hair dryer handle 22, while the circuit board is located inside the hair dryer handle 22. This design creates a T-shaped structure with the hair dryer head 21 and handle 22 positioned directly above the handle 22, allowing air to flow laterally from the top of the hair dryer. The circuit board and motor are arranged vertically, ensuring their centers of gravity are aligned, thus improving the stability and anti-tipping ability of the hair dryer.

[0049] Specifically, the length direction of the circuit board is the same as the length direction of the hair dryer handle 22. With this design, since the circuit board extends along the length direction of the hair dryer handle 22, the hair dryer handle 22 can be elongated, making it easier for the user to hold.

[0050] Furthermore, the hair dryer includes a noise reduction cover 7. A first air inlet 212 is provided on the side wall of the hair dryer head 21, and a first air outlet 211 is provided at one end of the hair dryer head 21. The first air inlet 212 and the first air outlet 211 are respectively connected to the air inlet end 31 and the air outlet end 32 of the fan assembly 3. The noise reduction cover 7 is set on the side wall of the hair dryer head 21 and covers the first air inlet 212. The noise reduction cover 7 has a hollow structure, and the rear section of the noise reduction cover 7 has a sealed structure. The front section of the noise reduction cover 7 is provided with at least one first through hole 71, which is used to allow external air to enter the hair dryer. Traditional fan covers have vents on their side walls. When the hair dryer is working, the noise generated will directly pass through the vents, making the surrounding environment noisy and harmful to human health. In contrast, this solution has a first through hole 71 on the front side wall of the noise reduction cover 7 to allow external air to enter the hair dryer. The noise generated by the fan assembly 3 will not be directly transmitted through the side wall of the noise reduction cover 7. The inner side wall of the noise reduction cover 7 can block the noise and reflect it, so that it is finally transmitted through the first through hole 71. In this process, the noise is partially reduced, achieving the effect of noise reduction.

[0051] Further, referring to Figure 7, the noise reduction cover 7 includes a rear housing and a front housing. The outer peripheral wall of the rear housing is a sealed structure, and the front housing has a front side wall and a circumferential wall. The first through hole 71 is provided on the front side wall, and the circumferential wall is connected to the front end wall of the rear housing. The noise generated by the operation of the fan assembly 3 is partially dissipated to the inner wall of the rear housing. Since the outer peripheral wall of the rear housing is a sealed structure, it can reduce some of the noise, achieving a noise reduction effect. By testing the noise of the blower before and after installing the noise reduction cover 7 in multiple directions, the test data shows that the noise after installing the noise reduction cover 7 is reduced by 2 decibels compared to the noise before installation.

[0052] Specifically, the circumferential wall of the front shell is also a sealed structure, which can block more noise and achieve a better noise reduction effect.

[0053] Furthermore, the projected length of the first through hole 71 in the horizontal direction is less than 40% of the projected length of the noise reduction cover 7 in the horizontal direction. In a specific embodiment, the projected length of the first through hole 71 in the horizontal direction is 39%, 35%, 30%, 25%, 20%, 15%, 10%, or 5% of the projected length of the noise reduction cover 7 in the horizontal direction. It should be noted that the blower head 21 is usually a long strip structure arranged front and back. Most of the noise generated by the blower assembly 3 will scatter towards the rear end along the inner cavity of the blower head 21. Designing the rear end of the noise reduction cover 7 as a sealed sidewall and placing the first through hole 71 at the front end is beneficial for noise reduction.

[0054] Furthermore, referring to Figure 10, a rotating nozzle 6 is provided at the first air outlet 211, which can rotate relative to the blower head 21 under the action of the airflow generated by the fan assembly 3. One end of the rotating nozzle 6 is rotatably connected to the blower head 21, and the other end of the rotating nozzle 6 is provided with a third air outlet, which is connected to the first air outlet 211. The rotating nozzle 6 can rotate relative to the blower head 21 under the action of the airflow generated by the fan assembly 3, making the air blown by the blower more uniform and expanding the blowing range of the blower to achieve large-area uniform airflow.

[0055] Specifically, the rotating blower nozzle 6 includes a nozzle body and a nozzle seat with openings at both ends. One end of the nozzle seat is inserted into the first air outlet 211, and the nozzle body is rotatably connected to the other end of the nozzle seat. The rotating blower nozzle 6 is provided with a rotation drive structure. The airflow from the first air outlet blows towards the rotation drive structure to drive the nozzle body to rotate relative to the nozzle seat. The airflow generated by the blower assembly 3 is blown towards the rotating blower nozzle 6 through the first air outlet 11. Part of the airflow is blown out from the third air outlet towards the target object, and part of it blows towards the rotation drive structure. The rotation drive structure is driven by the airflow to rotate the nozzle body, making the blowing range of the second air outlet 21 wider and the blowing more uniform, thus improving the blowing efficiency.

[0056] The inner wall of the mouthpiece holder is provided with a first bracket, and the first bracket is provided with a rotating shaft. The inner wall of the mouthpiece body is provided with a second bracket, and the second bracket is provided with a shaft hole. The rotating shaft is rotatably inserted into the shaft hole, and the mouthpiece body is inserted into the mouthpiece holder.

[0057] There are two third air outlets, arranged vertically on the front side wall of the mouthpiece body. The rotation drive structure includes a first guide block and a second guide block. The first guide block is formed by cutting off the right side of one third air outlet, and the second guide block is formed by cutting off the left side of the other third air outlet. The first guide block and the second guide block are centrally symmetrical.

[0058] The mouthpiece holder includes a mouthpiece holder body and a shell disposed on the outer peripheral wall of the mouthpiece holder body. An elastic part is provided on the side wall of the mouthpiece holder body, and an abutment block is provided on the inner wall of the shell. The inner wall of the elastic block abuts against the outer side wall of the mouthpiece body. The abutment block is used to squeeze the elastic part to deform the elastic block toward the mouthpiece body to adjust the rotation speed of the mouthpiece body.

[0059] In another embodiment, referring to Figures 8 and 9, this application also provides a blower system, including a housing assembly 1 and a blower as described above. The housing assembly 1 and the blower are spaced apart. A second air inlet 121 is provided on the side wall of the housing assembly 1, and a first air outlet 211 of the blower faces the second air inlet 121. The blower is used in conjunction with the housing assembly 1 to dry a pet's fur. The pet can be placed in the housing assembly 1, and the first air outlet 211 of the blower blows air towards the housing assembly 1 to dry the pet's fur inside the housing assembly 1.

[0060] Specifically, when the rotating blower nozzle 6 is installed at the first air outlet 211, the third air outlet faces the second air inlet 121.

[0061] Furthermore, the housing assembly 1 includes a housing assembly and a cover plate 11. The top wall of the housing assembly is provided with a first opening. The cover plate 11 is rotatably connected to the housing assembly and is used to cover the first opening. The second air inlet 121 is provided on the side wall of the housing assembly.

[0062] Furthermore, the housing assembly includes a front panel 12, a rear panel 13, two folding side panels 14, a bottom plate 15, and a first rotating structure 16. The bottom plate 15 is rotatably connected to the front side wall of the rear panel 13. The top wall of the rear panel 13 is provided with a third clearance notch that penetrates the rear side wall of the rear panel 13. The bottom wall of the cover plate 11 is provided with a sliding groove 111 arranged front and rear. One end of the first rotating structure 16 is rotatably connected to the inner wall of the third clearance notch, and the other end of the first rotating structure 16 is slidably connected to the sliding groove 111. Each folding side panel 14 includes a first sub-panel 141 and a second sub-panel 142. Each first sub-panel 141 and the second sub-panel 142 on the same side are rotatably connected.
