It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.

[0032] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0033] The embodiment of the utility model provides an air outlet assembly 10, which can be applied to a vertical hair dryer or a handheld hair dryer. The hair dryer includes a blower head for discharging air, and the handheld hair dryer also includes a handle connected to the blower head to provide a user with a grip; the vertical hair dryer also includes a bracket connected to the blower head, and the bracket is supported on the ground to free the user's hands. It should be noted that the air outlet assembly 10 in the present application can be used alone as the above-mentioned "blower head" and directly connected to the handle or bracket, or it can be set in the blower head as an internal component. The application scenario type of the embodiment of the utility model does not limit the structure of the air outlet assembly of the embodiment of the utility model.

[0034] For ease of explanation, Figure 1 and Figure 2 As shown, the air outlet assembly 10 is applied to a vertical hair dryer and is provided in the blower head 101 as an internal component for explanation.

[0035] Reference Figure 3 The air outlet assembly 10 includes a housing 11 and an air guide assembly 12. The housing 11 is hollow inside, and the air guide assembly 12 is arranged inside the housing 11. Figure 4 and Figure 5 A wind cavity 111, an air inlet area 112 and an air outlet area 113 are formed inside the shell 11. The air inlet area 112 and the air outlet area 113 are both connected to the ventilation cavity 111. The air inlet area 112 is used to introduce air into the wind cavity 111, and the air outlet area 113 is used to guide the air out of the wind cavity 111. The wind guide component 12 is arranged in the wind cavity 111, and divides the wind cavity 111 into a first sub-cavity 1111 and a second sub-cavity 1112. The first sub-cavity 1111 is connected to the air inlet area 112, and the second sub-cavity 1112 is connected to the air outlet area 113. The wind guide component 12 and / or the shell 11 are provided with a ventilation area 114, and the ventilation area 114 is connected to the first sub-cavity 1111 and the second sub-cavity 1112. The housing 11 has a plurality of air outlets 115 on one side, and the opening space of each air outlet 115 forms the air outlet area 113 . That is, each air outlet 115 is connected to the second sub-cavity 1112 to discharge the air of the second sub-cavity 1112 .

[0036] This arrangement ensures that the air does not directly enter the air outlet area 113 from the air inlet area 112. After entering from the air inlet area 112, the air first passes through the first sub-cavity 1111, then enters the second sub-cavity 1112 through the ventilation area 114, and finally is guided out through the air outlet area 113. It can be understood that the cross-sectional area of ​​the ventilation area 114 is smaller than the cross-sectional area of ​​the first sub-cavity 1111. Then, according to the "local static pressure phenomenon" of fluid mechanics, the fluid will gather along the path with a slower flow rate during the flow process. Therefore, the air first gathers in the first sub-cavity 1111 and then is guided to the second sub-cavity 1112 through the ventilation area 114; similarly, the cross-sectional area of ​​the air outlet 115 is smaller than the cross-sectional area of ​​the second sub-cavity 1112, and the air first gathers in the second sub-cavity 1112 and then is guided to the external environment through the air outlet area 113. Each air outlet 115 is arranged on the same side of the shell 11 and is located downstream of the second sub-chamber 1112. The second sub-chamber 1112 sends air to multiple air outlets 115 in a centralized manner to automatically realize air distribution. There is no order of precedence in the flow of air between the air outlets 115, and each air outlet 115 is located on the same side of the shell 11 and has a roughly equal static pressure. The second sub-chamber 1112 guides the air volume of each air outlet 115 to be roughly equal, and each air outlet 115 discharges air uniformly. There is no need to set air guide plates between each air outlet 115, nor is there a need to set air guide ducts connecting each air outlet 115 one by one, which is convenient for shortening the distance between each air outlet 115. At the same time, there is no need to reserve space for setting up air distribution structures such as air guide plates or air guide ducts in the air cavity 111, which is also convenient for reducing the volume of the air outlet component 10.

[0037] It should be noted that, refer to Figure 5 , the air cavity 111 only represents the part of the air guide assembly 12 adjacent to the air guide assembly 12 in the internal cavity of the shell 11, and does not refer to all the cavities inside the shell 11. It can be simply understood that the part of the cavity above the air guide assembly 12 is called the first sub-cavity 1111, and the part of the cavity below the air guide assembly 12 is called the second sub-cavity 1112. The above-mentioned "air inlet area 112", "air outlet area 113" and "ventilation area 114" all represent virtual spaces. Taking the air inlet area 112 as an example, when the shell 11 is provided with an opening directly connected to the ventilation cavity 111 and used for air intake, the space enclosed by the opening represents the air inlet area 112; when the aforementioned opening is provided with multiple openings, the area obtained by adding up the spaces enclosed by each opening represents the air inlet area 112; when the opening extends into a channel, the space in the channel represents the air inlet area 112. The shell 11 in the embodiment of the present application is provided with multiple air outlets 115, so the area obtained by adding up the spaces enclosed by each air outlet 115 represents the air outlet area 113.

[0038] It should be noted that the above “the air guide assembly 12 and / or the housing 11 is provided with a ventilation area 114” means that the ventilation area 114 can be provided on the air guide assembly 12, can be provided on the inner wall of the housing 11, can be provided on the air guide assembly 12 and the housing 11 respectively, and can also be provided between the air guide assembly 12 and the housing 11. The present application does not limit the specific location of the ventilation area 114, as long as the air in the first sub-cavity 1111 can enter the second sub-cavity 1112 through the ventilation area 114.

[0039] The embodiment of the utility model provides an air outlet assembly 10, which includes a housing 11 and an air guide assembly 12. The housing 11 has an air cavity 111 and an air inlet area 112 and an air outlet area 113 connected to the air cavity 111. The air inlet area 112 is used to introduce air into the air cavity 111, and the air outlet area 113 is used to guide the air out of the air cavity 111. The air guide assembly 12 is arranged in the air cavity 111, and divides the air cavity 111 into a first sub-cavity 1111 and a second sub-cavity 1112, wherein the first sub-cavity 1111 is connected to the air inlet area 112, and the second sub-cavity 1112 is connected to the air outlet area 113. The air guide assembly 12 and / or the housing 11 is provided with a ventilation area 114, and the ventilation area 114 is connected to the first sub-cavity 1111 and the second sub-cavity 1112. In this arrangement, air enters the first sub-cavity 1111 from the air inlet area 112, then reaches the second sub-cavity 1112 via the ventilation area 114, and finally is discharged through the air outlet area 113. The housing 11 has a plurality of air outlets 115 on one side, and the opening space of each air outlet 115 forms the above-mentioned air outlet area 113, so each air outlet 115 is connected to the second sub-cavity 1112. Each air outlet 115 is arranged on the same side of the shell 11 and has approximately the same static pressure. After the air gathers in the second sub-cavity 1112, it can be evenly guided to each air outlet 115 under the influence of approximately equal pressure differences, so that each air outlet 115 has approximately equal air outlet volume. There is no need to set air guide plates between the air outlets 115, and there is no need to set air guide ducts connecting each air outlet 115 one by one. Therefore, there is no need to reserve space for setting up wind guide plates or air guide ducts and other wind-dividing structures in the air cavity 111, which shortens the distance between the air outlets 115 and reduces the volume of the air outlet assembly 10.

[0040] In some embodiments, reference Figures 4 to 6 The plurality of air outlets 115 include a first air outlet 1151 and a second air outlet 1152, and the ventilation area 114 is at least partially disposed between the first air outlet 1151 and the second air outlet 1152. Figure 6 Comparison of the location of the central ventilation area Figure 4 The location of the central ventilation area, Figure 4 The position enclosed by the elliptical frame shown is Figure 6 The location of the middle ventilation area 114 is determined by Figure 4It can be seen that the ventilation area 114 is at least partially arranged between the first air outlet 1151 and the second air outlet 1152. The air entering the second sub-cavity 1112 from the ventilation area 114 will not be directly discharged through the air outlets 115, but will first be divided in the middle of the second sub-cavity 1112 to be respectively directed to the first air outlet 1151 and the second air outlet 1152. The air is "first gathered and then discharged" in the second sub-cavity 1112. The setting position of the ventilation area 114 makes the distance between the two air outlets and the ventilation area 114 approximately equal, so that the two maintain approximately equal static pressures, so that the air entering the second sub-cavity 1112 from the ventilation area 114 is evenly divided to the first air outlet 1151 and the second air outlet 1152. Refer to Figure 5 As shown in the gas flow diagram, the air entering the second sub-cavity 1112 from the ventilation area 114 is evenly divided in the middle of the second sub-cavity 1112, with one part flowing to the left toward the first air outlet 1151 and the other part flowing to the right toward the second air outlet 1152, so as to facilitate the first air outlet 1151 and the second air outlet 1152 to maintain uniform air volume and not easily produce a large air volume difference.

[0041] In some embodiments, reference Figure 4 and Figure 5 , the air cavity 111 extends along a first direction, and a plurality of air outlets 115 are sequentially arranged along the first direction, wherein the first direction is the direction indicated by the arrow N1 shown in the schematic diagram of the present application. It can be understood that the extension direction of the air cavity 111 indicates the direction in which the maximum outline dimension of the air cavity 111 is located. In the embodiment of the present application, the maximum outline dimension of the air cavity 111 is the length dimension of the air cavity 111, which means that the length direction of the air cavity 111 is in the first direction N1. Each air outlet 115 is arranged in the length direction of the air cavity 111, making full use of the length space of the air cavity 111, with a high space utilization rate, which is conducive to maintaining the volume balance of the air cavity 111.

[0042] In some embodiments, reference Figure 4 and Figure 5, the air inlet area 112 is located at one end of the air guide component 12 in the first direction N1, and the air outlet area 113 is located at one end of the air guide component 12 in the second direction N2, and the second direction N2 is perpendicular to the first direction N1. The air entering from the air inlet area 112 is guided to the first sub-cavity 1111 along the first direction N1, and then guided to the second sub-cavity 1112 along the direction perpendicular to the first direction N1 (the second direction N2). The air inlet area 112 and the air outlet area 113 are not on the same straight line, and the air in the air inlet area 112 will not directly pass through the ventilation area 114 along a straight line, but will be guided from the air inlet area 112 to the air outlet area 113 in a roughly "L" shape. Due to the limitation of the transmission path, the air flow rate entering the first sub-cavity 1111 is greater than the air flow rate discharged from the first sub-cavity 1111, which can be regarded as the air "first gathered and then discharged" in the first sub-cavity 1111. According to the turbulence effect and the airflow cutting effect, the airflow speed of the straight-line blowing is faster, and the speed difference with the surrounding static air is large, which is easy to form a large speed gradient, thereby driving the air molecules to produce additional collisions and vortices, and then generating large noise. The air duct (the area from the air inlet area 112 to the air outlet area 113) in the air outlet assembly 10 in the embodiment of the utility model is roughly arranged along the "L" shape, so that the air is roughly guided from the air inlet area 112 to the air outlet area 113 in the "L" shape, and the air does not flow in a straight line, which is conducive to reducing the noise in the air outlet assembly 10.

[0043] On the other hand, in one embodiment, the air outlet area 113 is arranged so that each air outlet 115 is located at one end of the air guide assembly 12 in the second direction N2. Then, in combination with the above, it can be known that the second sub-cavity 1112 imports and exports air along the second direction N2. The air flows in the same direction on the upstream and downstream sides of the second sub-cavity 1112. The air is preferentially affected by the pressure difference of the air outlet 115 in the flow direction of the second sub-cavity 1112 and is directly divided, and is not easily blocked and collided by the inner wall of the shell 11 and indirectly divided. The number of air divisions in the second sub-cavity 1112 is related to the number of air outlets 115, which is conducive to each air outlet 115 maintaining a roughly equal air volume, so as to improve the user experience.

[0044] It should be noted that the above-mentioned “first direction N1” refers to Figure 5 The arrow N1 in the middle points to the direction (left and right direction), and the air inlet area 112 is located at the left end of the first direction N1; the "second direction N2" indicates Figure 5 The arrow N2 in the middle points to the direction (up and down direction), and the air outlet area 113 is located at the lower end of the second direction N2. The air in the wind cavity 111 is first introduced into the first sub-cavity 1111 roughly from left to right, and then introduced into and exported from the second sub-cavity 1112 roughly from top to bottom.

[0045] In some embodiments, reference Figure 7The air guide assembly 12 includes a first mounting plate 121 and a heating element 122. The first mounting plate 121 is disposed in the housing 11 and extends along the first direction N1. The first mounting plate 121 is disposed in the housing 11 and divides the air cavity 111 into a first sub-cavity 1111 and a second sub-cavity 1112. Figure 4 and Figure 5 From the perspective of the embodiment of the present invention, the part of the cavity above the first mounting plate 121 is the first sub-cavity 1111, and the part of the cavity below the first mounting plate 121 is the second sub-cavity 1112. The first mounting plate 121 and / or the housing 11 have a ventilation structure that forms a ventilation area 114, and the air in the first sub-cavity 1111 passes through the ventilation structure and enters the second sub-cavity 1112. The heating element 122 is used to heat the air, that is, the air guide assembly 12 can heat the air while guiding the air. Compared with setting the heating element 122 at other positions of the air outlet assembly 10, setting the heating element 122 in the air cavity 111 can use the air flow in the first sub-cavity 1111 and the second sub-cavity 1112 to take away the heat on the surface of the heating element 122 at least twice, which is convenient for reducing the heat accumulation on the surface of the air guide assembly 12, so as to reduce the risk of damage to the air guide assembly 12 due to excessive temperature. Furthermore, the air flows in the first sub-cavity 1111 and the second sub-cavity 1112 can be regarded as "first gathering and then discharging", so that the heating element 122 can fully contact the air to achieve air heating, and the air outlet assembly 10 has a higher heating efficiency.

[0046] Specifically, in some possible implementations, the ventilation structure may be a hole or slot-shaped structure provided on the first mounting plate 121, a hole or slot-shaped structure provided on the inner wall of the housing 11, a hole or slot-shaped structure provided on the first mounting plate 121 and the inner wall of the housing 11, or a gap provided between the first mounting plate 121 and the housing 11. Of course, the above-mentioned embodiments do not necessarily exist independently, and multiple ventilation structures may exist at the same time. Figure 6 , Figure 6 The part of the housing 11 (upper housing 117) that blocks the first mounting plate 121 is omitted. Figure 6 In some of the embodiments shown, the first mounting plate 121 is provided with a plurality of through holes, each of which is spaced apart along the first direction N1. At the same time, there is a gap between the first mounting plate 121 and the inner wall of the housing 11. Each of the through holes and the gap between the first mounting plate 121 and the inner wall of the housing 11 together form a ventilation area 114 (the position enclosed by the dotted ellipse). In addition, the first mounting plate 121 is spaced apart from the housing 11, which can reduce the risk of heat from the heating element 122 being directly transferred to the housing 11 under the action of heat conduction and scalding the user.

[0047] It should be noted that, in some possible implementation schemes, the heating element 122 can be arranged in the first sub-cavity 1111 and / or the second sub-cavity 1112. Specifically, the heating element 122 can be arranged in the first sub-cavity 1111 or the second sub-cavity 1112 as a separate component (such as an electromagnetic heating plate or an electromagnetic pole plate), and the heating element 122 can also be arranged in the first sub-cavity 1111 and the second sub-cavity 1112 respectively. Of course, the air guide assembly 12 can also be provided with multiple heating elements 122 at the same time, and each heating element 122 is simultaneously arranged in the first sub-cavity 1111 or the second sub-cavity 1112, or can be arranged in the first sub-cavity 1111 and the second sub-cavity 1112 respectively. The present application does not limit the specific setting position and setting quantity of the heating element 122, as long as there is at least one heating element 122 in any sub-cavity and the heating element 122 is connected to the first mounting plate 121.

[0048] It is understandable that even if the heating element 122 is only disposed in one sub-cavity, the effect of "taking away the heat from the surface of the heating element 122 at least twice by utilizing the air circulation turbulence of the first sub-cavity 1111 and the second sub-cavity 1112" can be achieved. The heat of the heating element 122 is inevitably transferred to the first mounting plate 121 under the action of air flow, and the first mounting plate 121 separating the first sub-cavity 1111 and the second sub-cavity 1112 exists in both sub-cavities. Then, the air circulation turbulence in the first sub-cavity 1111 and the second sub-cavity 1112 can contact the first mounting plate 121 and take away the heat from the surface of the first mounting plate 121, assuming that the heating element 122 is disposed in the second sub-cavity 1112. The air flow in the second sub-cavity 1112 directly contacts the heating element 122 and takes away the heat from the surface of the heating element 122 at least once, and the air flow in the first sub-cavity 1111 takes away the heat from the upper surface of the first mounting plate 121 at least once. Under the effect of heat conduction, the air flow in the first sub-cavity 1111 indirectly realizes the cooling of the heating element 122, so it can still be regarded as "the two sub-cavities respectively take away the heat from the surface of the heating element 122".

[0049] In some embodiments, reference Figure 4 and Figure 7 , a heating element 122 is provided in both the first sub-cavity 1111 and the second sub-cavity 1112. The heating element 122 exists in both sub-cavities and can contact the air in both sub-cavities, so that the air outlet assembly 10 can blow out warm air efficiently. In addition, assuming that the heating element 122 is provided as a separate component in both the first sub-cavity 1111 and the second sub-cavity 1112, specifically, the heating element 122 can be a resistance wire coiled on the first mounting plate 121, then the air flow in both the first sub-cavity 1111 and the second sub-cavity 1112 can directly contact the resistance wire, and the air flow in the two sub-cavities can respectively take away the heat on the surface of the coiled resistance wire, so that the heat dissipation efficiency in the air cavity 111 is higher.

[0050] In some embodiments, reference Figure 5 and Figure 7 The housing 11 has a hollow air inlet 116, the air inlet 116 has an air inlet end 1161 and an air outlet end 1162, an air inlet area 112 is formed between the air inlet end 1161 and the air outlet end 1162, and the air outlet end 1162 is connected to the air cavity 111. In other words, the air inlet 116 is a channel-shaped component with a certain length of space, and the air inlet area 112 represents the channel space in the air inlet 116. The air outlet assembly 10 also includes a fan 13 for forming a negative pressure to drive the gas flow, the fan 13 is arranged between the air inlet end 1161 and the air outlet end 1162, and under the influence of the fan blades of the fan 13, the air passing through the fan 13 is accelerated to flow to the first sub-cavity 1111. On the one hand, the fan 13 is not arranged in the wind cavity 111 and is not easily affected by the hot air in the wind cavity 111. The fan 13 is not easy to work in a high temperature environment, which is beneficial to extending the service life of the fan 13; on the other hand, the fan 13 is arranged between the air outlet end 1162 and the air inlet end 1161 and is located in the air inlet area 112 inside the shell 11, so that the fan 13 is arranged adjacent to the first sub-cavity 1111, which facilitates the concentration of air volume in the first sub-cavity 1111.

[0051] In some embodiments, reference Figure 7 The housing 11 includes an upper shell 117 and a lower shell 118, and each air outlet 115 is arranged on the lower shell 118. The upper shell 117 and the lower shell 118 jointly form an air cavity 111 and an air inlet 116, which reduces the difficulty of processing and forming the air cavity 111 and the air inlet 116. Compared with the embodiment in which the upper shell 117 and the lower shell 118 jointly form the air outlet 115, each air outlet 115 in the embodiment of the present application is located in the lower shell 118, so that each air outlet 115 has a complete wall surface, which facilitates the air discharged through the air outlet 115 to blow directly to the user, and the air outlet 115 is not prone to the risk of air leakage, and the user can obtain a larger air volume.

[0052] Reference Figure 1 and Figure 2 The present application also provides a vertical hair dryer, which includes a blower head 101 and a bracket 102. The blower head 101 is connected to the bracket 102, and the bracket 102 is supported on the ground to free the user's hands. The blower head 101 includes the above-mentioned air outlet assembly 10 to extend the service life of the vertical hair dryer by reducing the heat accumulation inside the vertical hair dryer.

[0053] In some possible implementations, the fan head 101 is movably connected to the bracket 102 to change the outlet angle of the air outlet assembly 10, and / or to make the air outlet assembly 10 move closer to or farther from the bracket 102 as the fan head 101 moves as a whole. For example, the fan head 101 can be hinged to the bracket 102 through a universal ball joint, and the fan head 101 can be driven to rotate around the bracket 102. Figure 1 The fan head 101 rotates counterclockwise as shown, and the fan head 101 drives the air outlet assembly 10 to move away from the bracket 102 to discharge air; the fan head 101 is driven around Figure 1 As shown in the clockwise direction, the fan head 101 drives the air outlet assembly 10 to approach the bracket 102 to discharge air, and in this state, the fan head 101 is as shown in FIG. Figure 1 The side of the adjacent bracket 102 shown can be understood as the fan head 101 at Figure 1 The blower head 101 is in a folded storage state in the viewing angle to save the storage space required for the vertical hair dryer in this application. Of course, the blower head 101 can also be arranged along Figure 1 The front and rear directions shown are rotated to allow air to flow in a manner compatible with the user's posture.

[0054] It is understandable that "the fan head 101 is hinged to the bracket 102 through a universal ball joint" is only one of the implementation schemes. In some possible implementation schemes, the fan head 101 can also move relative to the bracket 102 through a telescopic arm. However, no matter what kind of structural active connection is used between the fan head 101 and the bracket 102, the fan head 101 can move relative to the bracket 102 to change the air outlet angle of the air outlet component 10, and / or make the air outlet component 10 move closer to or away from the bracket 102 to exhaust air. This arrangement allows the vertical hair dryer in the present application to be compatible with air outlets for users of different heights and for the same user to be compatible with air outlets in different positions (such as the top of the head and behind the head), providing a higher user experience.

[0055] In some possible implementations, the bracket 102 may be provided with a lifting mechanism to allow the fan head 101 to rise or fall to a certain height, so as to be compatible with the user's sitting posture or the height of different users. The lifting mechanism may be structurally controlled, such as receiving external force from the user through a screw structure, and the user screwing the screw structure to raise or lower the fan head 101; the lifting mechanism may also be electrically inductively controlled, such as a visual sensing system and / or a height sensing system may be provided on the bracket 102, and the visual sensing system and / or the height sensing system senses the height of the user's head and adjusts the bracket 102 to rise or fall to the corresponding height, so as to automatically realize human-computer interaction and improve the user experience.

[0056] Reference Figure 8 and Fig. 9 The blower head 101 of the vertical hair dryer also includes a housing 20 and a circuit board 30, and the housing 20 is movably connected to the bracket 102 (such as Figure 1As shown), a mounting cavity 21 is formed inside the housing 20, and the air outlet component 10 is arranged in the mounting cavity 21, and the mounting cavity 21 is connected to the ventilation cavity 111. The present application sets a housing 20 that is sleeved on the outside of the shell 11, which can improve the aesthetics of the fan head 101 on the one hand, and can use the gap between the housing 20 and the shell 11 to isolate the heat of the air outlet component 10. The circuit board 30 is arranged in the mounting cavity 21, and the circuit board 30 is used to control the air outlet state of the air outlet component 10, including but not limited to controlling the start and stop of the air outlet component 10, controlling the size of the air outlet air volume of the air outlet component 10, and controlling the temperature of the air outlet component 10. The circuit board 30 is arranged in the mounting cavity 21 instead of in the air outlet component 10, so that the circuit board 30 works in a cold air state and is not easily disturbed by the hot air of the air outlet component 10, which is beneficial to extend the service life of the circuit board 30 and maintain the stability of the circuit connection, thereby extending the service life of the vertical hair dryer and improving the safety of the vertical hair dryer.

[0057] Compared to setting the circuit board 30 in the air cavity 111, specifically, compared to the implementation mode in which the circuit board 30 is set between the first air outlet 1151 and the second air outlet 1152, the embodiment of the present application sets the circuit board 30 in the installation cavity 21 of the outer layer of the air cavity 111, which is convenient for reducing the distance between the first air outlet 1151 and the second air outlet 1152, and the air cavity 111 does not need to reserve installation space and line layout space for the circuit board 30, which is convenient for reducing the volume of the air cavity 111.

[0058] In some embodiments, reference Fig. 9 The housing 20 has an outer air port 22 connected to the mounting cavity 21. The outer air port 22 is disposed adjacent to the air inlet area 112 of the air outlet assembly 10. The outer air port 22 is used to introduce air from the external environment into the air inlet area 112 of the air outlet assembly 10. Specifically, refer to Fig. 9 The circuit board 30 is located on the side of the outer air outlet 22 away from the air outlet assembly 10. Fig. 9 In some of the embodiments shown, the air outlet component 10 is located on the right side of the external air outlet 22, and the circuit board 30 is located on the left side of the external air outlet 22. The circuit board 30 is not between the external air outlet 22 and the air outlet component 10, so as not to interfere with and block the air intake from the external air outlet 22. The circuit board 30 is arranged away from the air outlet component 10 and is more easily exposed to cold air, so as to achieve heat exchange with the cold air at the external air outlet 22, which is beneficial to the heat dissipation of the circuit board 30 and reduces the heat accumulation on the surface of the circuit board 30.

[0059] In some embodiments, reference Fig. 9The fan head 101 also includes an atmosphere light 40 electrically connected to the circuit board 30. The circuit board 30 is used to control the working state of the atmosphere light 40 according to the air outlet state of the air outlet component 10, including but not limited to switching the display color of the atmosphere light 40 according to the air outlet temperature of the air outlet component 10, controlling the atmosphere light 40 to turn on or off according to the start and stop of the air outlet component 10, and controlling the atmosphere light 40 to flash according to the air volume of the air outlet component 10.

[0060] The present application does not limit the specific installation position of the atmosphere light 40. Specifically, the atmosphere light 40 can be installed at the end (left end) of the air outlet component 10 away from the first direction N1 as shown in the schematic diagram of the present application. Of course, the atmosphere light 40 can also be installed at the end (right end) of the air outlet component 10 along the first direction N1. The atmosphere light 40 can also be set at the connection position between the fan head 101 and the bracket 102.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
