[0002] At present, most fans on the market adopt a spring detent structure for manual pitching and yawing. This structure has a good pitching adjustment feel and can stably fix the head angle. However, the spring detent parts are difficult to assemble, and since the spring detent structure relies on a slot for positioning, it can only be fixed at an angle for adjustment, with limited yawing space and cannot be adjusted at any angle. Summary of the Utility Model

[0007] A blocking member, which is disposed between the rotating end and the inner wall of the mating hole;
[0008] Wherein, the blocking member is used to generate a resistance to prevent the head component from continuing to rotate under the action of gravity when the head component rotates relative to the bracket to a preset position.
[0009] In one embodiment, an installation groove extending circumferentially and closing along its own circumference is formed by recessing the circumferential side of the rotating end, and the blocking member is sleeved in the installation groove and is in interference fit with the groove wall of the installation groove.

[0011] In one embodiment, the bracket includes a main body, a rotating shaft and a limiting portion. The limiting portion protrudes from the circumferential side of the rotating end. When the mounting member is controlled to rotate relative to the bracket, the mating portion rotates around the circumferential side of the rotating end relative to the limiting portion and abuts against the limiting portion.
[0012] In one embodiment, the bracket includes a main body, a rotating shaft and a limiting portion. The rotating shaft is provided at one end of the main body close to the mounting member, and the limiting portion protrudes from the circumferential side of the rotating shaft. Both the rotating shaft and the limiting portion are movably mated in the mating hole.
[0013] In one embodiment, the limiting portion extends along the circumferential direction of the rotating end, and the central angle subtended by the circumferential extension of the limiting portion around the rotating end is a preset angle A, and the preset angle A satisfies the condition: 90° ≤ A ≤ 180°;
[0014] The engaging portion extends along the circumferential direction of the inner wall of the engaging hole, and the central angle subtended by the circumferential extension of the engaging portion around the inner wall of the engaging hole is a preset angle B, and the preset angle B satisfies the condition: 90° ≤ B ≤ 180°.
[0015] In one embodiment, the preset angle A and the preset angle B jointly satisfy the condition: A + B = 270°.
[0016] In one embodiment, the mounting member includes a first sub-mounting member and a second sub-mounting member.

[0017] In one embodiment, it further includes a housing, a fan blade and a driving member. An air duct is formed inside the housing. The mounting member is connected to the air inlet end of the air duct and is connected to the housing. The fan blade is connected to the driving end of the driving member and is arranged along the circumferential direction of the driving end. The driving member and the fan blade are located inside the air duct and are both arranged on one side of the mounting member facing the air outlet end of the air duct.
[0018] A fan includes a body and the head assembly in the foregoing embodiment, and the head assembly is connected to the body.
[0019] For the above-mentioned head assembly and fan, the head assembly includes a head component, a bracket and a blocking member. The head component includes a mounting member and a head mounting member connected to the mounting member. Mating holes are respectively formed on opposite sides of the mounting member. The bracket has a rotating end connected to the mounting member, and the rotating end is movably connected to the mating hole.

The blocking member is used to generate a resistance to prevent the head component from continuing to rotate under the action of gravity when the head component rotates relative to the bracket to a preset position. In the present application, by arranging the blocking member between the rotating end and the inner wall of the mating hole, the resistance generated by the blocking member on the rotating end and the inner wall of the mating hole is used to offset the gravity received by the mounting member, so as to prevent the mounting member from rotating relative to the bracket under the action of gravity, so that the mounting member can be fixed at any specific angle required by the user, with flexible use and convenient operation, which is beneficial to improving the user experience.

[0040] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a fan (not shown in the figure). The fan includes a body (not shown in the figure) and a head assembly 100. The head assembly 100 includes a head component 200 and a bracket 300. The head component 200 includes a mounting member 20 and a head fitted on the mounting member 20. The mounting member 20 is connected to the body through the bracket 300, and opposite sides of the mounting member 20 are respectively provided with mating holes 201. The bracket 300 is correspondingly disposed on opposite sides of the mounting member 20 where the mating holes 201 are provided. The bracket 300 has a rotating end close to the mounting member 20. The rotating end is used for movably mating in the mating holes 201. And when the mounting member 20 is controlled to pitch and rotate relative to the bracket 300, the mounting member 20 can drive the head to move synchronously, and the inner wall of the mating holes 201 can rotate relative to the bracket 300 synchronously around the circumference of the rotating end.
[0041] In some embodiments, the head further includes a housing (not shown in the figure), a fan blade (not shown in the figure) and a driving member (not shown in the figure). A wind channel is formed inside the housing. The mounting member 20 is fitted on the air inlet end of the wind channel and connected to the housing. The fan blade is fitted on the driving end of the driving member and is arranged along the circumference of the driving end. The driving member and the fan are located inside the wind channel and are both arranged on one side of the mounting member 20 facing the air outlet end of the wind channel.
[0042] It can be understood that during the operation of the fan, the driving member can drive the fan blade to rotate. During the rotation of the fan blade, the outside air will be sucked into the wind channel from the air inlet of the wind channel, and under its own action, the air circulation will be accelerated to form an air flow, and then the air flow will be blown out from the air outlet of the wind channel, so as to play a role in accelerating the outside air circulation to achieve heat dissipation. The user can control the mounting member 20 to pitch and rotate relative to the bracket 300 and the body according to actual needs. The housing, the fan blade and the driving member can move synchronously under the drive of the mounting member 20, so as to realize flexible adjustment of the air outlet direction of the fan.
[0043] In some embodiments, please refer to Figure 1 and Figure 3, the head assembly 100 further includes a blocking member 400. The blocking member 400 is disposed between the rotating end and the inner wall of the mating hole 201, and the blocking member 400 is configured to generate a resistance that prevents the head assembly 200 from continuing to rotate under the action of gravity when the head assembly 200 rotates relative to the bracket 300 to a preset position.
[0044] In the present application, the mounting member 20 is rotatably mated with the bracket 300, and other components such as a housing, a fan blade, and a driving member are also assembled on the mounting member 20. Therefore, when the mounting member 20 rotates relative to the bracket 300 to any specific angle (preset position) under the control of the user, the mounting member 20 is subjected to the combined action of its own gravity and the gravity of other components such as the housing, the fan blade, and the driving member, and the mounting member 20 will rotate relative to the bracket 300 under the action of this gravity and deviate from the specific angle required by the user, affecting the customer experience.
[0045] In the present application, by providing the blocking member 400 between the rotating end and the inner wall of the mating hole 201, the resistance generated by the blocking member 400 against the rotating end and the inner wall of the mating hole 201 is used to offset the gravity received by the mounting member 20, thereby preventing the mounting member 20 from rotating relative to the bracket 300 under the action of gravity, so that the mounting member 20 can be fixed at any specific angle (preset position) required by the user, with flexible use and convenient operation, which is beneficial to improving the user experience.
[0046] It should be noted that during the process of the mounting member 20 being controlled to rotate relative to the bracket 300, the angle of rotation of the mounting member 20 is different, and the magnitude of the gravity received by the mounting member 20 is also different. Therefore, the resistance generated by the blocking member 400 should not be less than the maximum gravity received by the mounting member 20 during the process of being controlled to rotate relative to the bracket 300.
[0047] Among them, the specific value range of the resistance generated by the blocking member 400 is obtained through experimental testing and is not limited herein.
[0048] In some embodiments, please refer to Figure 3 and Figure 4 , an installation groove 33 extending circumferentially and closing along its own circumference is formed by recessing the circumferential side of the rotating end, and the blocking member 400 is sleeved in the installation groove 33 and is in interference fit with the groove wall of the installation groove 33.
[0049] It can be understood that the groove wall of the installation groove 33 can clamp the blocking member 400 to enhance the assembly stability of the blocking member 400, so as to reduce the blocking member 400 from detaching from the rotating end of the bracket 300 and the mating hole 201, thereby effectively improving the stability and safety of the fan operation.
[0050] In some embodiments, please refer to Figure 2 and Figure 3, radially on the rotating end, the blocking member 400 is clamped between the bottom wall of the installation groove 33 and the inner wall of the mating hole 201. That is to say, one side surface of the blocking member 400 along the radial direction of the rotating end abuts against the bottom wall of the installation groove 33, and the other side surface of the blocking member 400 along the radial direction of the rotating end abuts against the inner wall of the mating hole 201. When there is a tendency of relative movement between the rotating end and the inner wall of the mating hole 201 under the action of gravity, the blocking member 400 will generate a resistance to the rotating end and the inner wall of the mating hole 201 to offset the gravity received by the mounting member 20, thereby preventing the mounting member 20 from rotating relative to the bracket 300 under the action of gravity, so that the mounting member 20 can be fixed at any specific angle (preset position) required by the user, with flexible use and convenient operation, which is beneficial to improving the user experience.
[0051] In some embodiments, please refer to Figure 3 , the blocking member 400 is in interference fit with the rotating end and the inner wall of the mating hole 201.
[0052] The specific shape of the blocking member 400 is not limited, for example: annular, square, cylindrical, etc. In some embodiments, please refer to Figure 1 and Figure 7 , the blocking member 400 is annular.
[0053] The specific material of the blocking member 400 is not limited. In some embodiments, please refer to Figure 1 and Figure 7 , the material of the blocking member 400 is rubber. It can be understood that using rubber to make the blocking member 400 is beneficial to cost saving, and rubber has excellent wear resistance and elasticity, which can better relieve the impact between the rotating end and the inner wall of the mating hole 201, reduce the probability of product damage, and effectively improve the service life of the product.
[0054] In some embodiments, please refer to Figure 1 and Figure 4 , a limiting portion 32 protrudes from the circumferential side of the rotating end, and a mating portion 202 is formed on the inner wall of the mating hole 201. When the mounting member 20 is controlled to rotate relative to the bracket 300, the mating portion 202 can rotate relative to the limiting portion 32 around the circumferential side of the rotating end, and the limiting portion 32 is located on the rotation path of the mating portion 202 and can abut against the limiting portion 32.
[0055] It can be understood that when the rotating end is movably fitted in the fitting hole 201, the limiting portion 32 and the fitting portion 202 are arranged oppositely around the circumference of the rotating end. Correspondingly, when the user controls the fitting 20 to rotate the fitting 20 relative to the bracket 300 and the fuselage in a pitching manner, the inner wall of the fitting hole 201 and the fitting portion 202 both rotate around the axis of the rotating end. The limiting portion 32 is located on the path of the circumferential rotation of the fitting portion 202 around the rotating end. In this way, the limiting portion 32 can abut against the fitting portion 202 to limit the pitching rotation angle of the fitting 20 relative to the bracket 300 and the fuselage.
[0056] It should be noted that when the nose assembly 100 is correspondingly assembled with the fuselage of the fan, generally other components such as cables and pipes are also fitted at the rear side of the fuselage, that is, the air inlet end of the nose assembly 100. Therefore, in this application, by providing the limiting portion 32 and the fitting portion 202 to limit the pitching rotation angle of the fitting 20 relative to the bracket 300 and the fuselage, the nose assembly 100 is kept blowing air to the front side of the fuselage, thereby avoiding entanglement of other components such as cables and pipes and ensuring the stability and safety of the fan operation.
[0057] In some embodiments, please refer to Figure 3 and Figure 4 , the bracket 300 includes a main body 30, a rotating shaft 31 and a limiting portion 32. A rotating shaft 31 is provided at one end of the main body 30 close to the fitting 20, and a limiting portion 32 protrudes from the circumference of the rotating shaft 31.
[0058] It can be understood that the rotating shaft 31 of the bracket 300 corresponds to the rotating end of the bracket 300. When the rotating shaft 31 is movably fitted in the fitting hole 201, the limiting portion 32 and the fitting portion 202 are arranged oppositely around the circumference of the rotating shaft 31. Correspondingly, when the user controls the fitting 20 to rotate the fitting 20 relative to the bracket 300 and the fuselage in a pitching manner, the inner wall of the fitting hole 201 and the fitting portion 202 both rotate around the axis of the rotating shaft 31. The limiting portion 32 is located on the path of the circumferential rotation of the fitting portion 202 around the rotating shaft 31. In this way, the limiting portion 32 can abut against the fitting portion 202 to limit the pitching rotation angle of the fitting 20 relative to the bracket 300 and the fuselage. [[ID=???]] [[ID=???]]
[0059] In some embodiments, please refer to Figure 4 and Figure 8 , the limiting portion 32 extends around the circumference of the rotating end, and the central angle subtended by the extension of the limiting portion 32 along the circumference of the rotating end is a preset angle D1, and the preset angle D1 satisfies the condition: 90°≤D1≤180°.
[0060] In the present application, the preset angle D1 can be understood as follows: when the central angle subtended by the circumferential extension of the limiting portion 32 along the circumferential direction of the rotating end is the preset angle D1, it can ensure that the circumferential extension of the limiting portion 32 along the circumferential direction of the rotating end has sufficient length to guarantee its own structural strength, thereby reducing the probability of damage when the limiting portion 32 abuts against the mating portion 202, which is beneficial to improving the service life of the product.
[0061] In some embodiments, please refer to Figure 8 , the mating portion 202 extends circumferentially along the inner wall of the mating hole 201, and the central angle subtended by the circumferential extension of the mating portion 202 along the inner wall of the mating hole 201 is the preset angle D2, and the preset angle D2 satisfies the condition: 90° ≤ D2 ≤ 180°.
[0062] In the present application, the preset angle D2 can be understood as follows: when the central angle subtended by the circumferential extension of the mating portion 202 along the circumferential direction of the rotating end is the preset angle D2, it can ensure that the circumferential extension of the mating portion 202 along the circumferential direction of the rotating end has sufficient length to guarantee its own structural strength, thereby reducing the probability of damage when the limiting portion 32 abuts against the mating portion 202, which is beneficial to improving the service life of the product.
[0063] In some embodiments, please refer to Figure 2 and Figure 8 , the preset angle D1 and the preset angle D2 jointly satisfy the condition: 180° ≤ D1 + D2 ≤ 270°.
[0064] It can be understood that when the user controls the mounting member 20 to rotate the mounting member 20 relative to the bracket 300 and the fuselage in a pitching manner, the inner wall of the mating hole 201 and the mating portion 202 both rotate around the axial direction of the rotating end, and the limiting portion 32 is located on the circumferential rotation path of the mating portion 202 around the rotating end. That is to say, the central angle subtended by the circumferential extension of the limiting portion 32 along the circumferential direction of the rotating end is the same as the central angle subtended by the circumferential extension of the mating portion 202 along the circumferential direction of the rotating end. When 180° ≤ A + B ≤ 270°, the range of the central angle subtended by the spaced space between the limiting portion 32 and the mating portion 202 along the circumferential direction of the rotating end corresponds to 0° - 180°. In this way, the mounting member 20 can rotate relative to the fuselage by an angle of 0° - 180° so that the nose assembly 100 keeps blowing air to the front side of the fuselage, thereby avoiding entanglement of other components such as cables and pipes and ensuring the stability and safety of the fan operation.
[0065] In some embodiments, please refer to Figure 5 and Figure 6, the mounting member 20 includes a first sub-mounting member 203 and a second sub-mounting member 204. First mating grooves 2031 and 2032 are respectively formed at opposite ends of the first sub-mounting member 203, and third mating grooves 2041 and fourth mating grooves 2042 are respectively formed at opposite ends of the second sub-mounting member 204. The first sub-mounting member 203 and the second sub-mounting member 204 are fitted together so that the first mating groove 2031 and the third mating groove 2041 correspond to form a mating hole 201, and the second mating groove 2032 and the fourth mating groove 2042 correspond to form another mating hole 201.
[0066] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0067] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
