DETAILED DESCRIPTION

[0039] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0041] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0042] A fan is a device that uses an electric motor to rotate blades, generating airflow. It is primarily used for air circulation, cooling, ventilation, and heat dissipation. Fans are widely used in homes, offices, industrial facilities, and other settings.

[0043] During fan operation, due to the large size of the fan blades, it is easy for the fan to rotate unbalanced. This imbalance will cause slight vibrations, which are transmitted to the entire fan, causing the moving parts (left and right swing head, up and down swing head, connecting support rods and other components) and the entire head to shake and sway, which in turn causes the fan to make unusual noises during operation.

[0044] Therefore, in order to solve the technical problem that the vibration caused by the imbalance of the fan blades causes the moving parts and the entire head of the fan to shake and sway easily, which in turn causes abnormal noise in the fan during operation, the present application provides a fan that can effectively absorb and damp the vibration generated by the fan blades, reduce the vibration amplitude, and thereby reduce the vibration transmission between the fan head and the machine head, thereby reducing the shaking and swaying of the fan head and the machine head due to the influence of the vibration, thereby reducing the noise generated by the fan during operation. Please refer to the following embodiments for details.

[0045] See also Figures 1 to 13 The present application provides a fan 1 including a machine head 20 , a fan head 30 and a shock absorbing assembly 40 .

[0046] The fan head 30 is detachably connected to the machine head 20 .

[0047] When the fan head 30 is connected to the machine head 20 , the shock absorbing assembly 40 is located at the connection between the machine head 20 and the fan head 30 , and abuts between the fan head 30 and the machine head 20 .

[0048] The fan 1 provided in this embodiment is provided with a shock absorbing assembly 40 at the connection between the machine head 20 and the fan head 30, and the shock absorbing assembly 40 abuts between the fan head 30 and the machine head 20. In this way, when the fan blades 31 in the fan head 30 vibrate due to imbalance, the shock absorbing assembly 40 can effectively absorb and damp the vibration generated by the fan blades 31, reduce the vibration amplitude, and reduce the vibration transmission between the fan head 30 and the machine head 20, thereby reducing the shaking and swaying of the fan head 30 and the machine head 20 due to the influence of vibration, thereby reducing the noise generated by the fan 1 during operation.

[0049] In some embodiments, the fan head 30 can be detachably connected to the machine head 20 by means of a threaded connection, a snap connection, a magnetic connection, or a latch connection.

[0050] In this way, the detachable connection between the machine head 20 and the fan head 30 simplifies the assembly process and improves the assembly efficiency of the fan 1 .

[0051] In some embodiments, the fan head 30 is provided with a plug slot 33, and the machine head 20 is provided with a plug end 23, and the plug end 23 can be plugged and matched with the fan head 30;

[0052] The shock absorbing assembly 40 includes a plurality of first shock absorbing members 410 , which are arranged in sequence along the circumference of the plug-in end 23 . When the plug-in end 23 is plugged into the plug-in slot 33 , each of the first shock absorbing members 410 abuts between the fan head 30 and the plug-in end 23 .

[0053] In this way, each of the first shock absorbing members 410 abuts between the fan head 30 and the plug end 23 , thereby reducing vibration between the fan head 30 and the plug end 23 , and further reducing vibration between the fan head 30 and the machine head 20 .

[0054] In addition, by providing a plug-in slot 33 on the fan head 30, the two ends of the first shock absorber 410 can be fixed to the fan head 30 and the machine head 20 respectively, thereby preventing the fan head 30 from shaking and swaying due to vibration caused by the imbalance of the fan blades 31.

[0055] In some embodiments, the plug end 23 is provided with a plurality of first mounting grooves 231 , and the plurality of first mounting grooves 231 correspond one-to-one to a plurality of first shock absorbers 410 , respectively. Each first shock absorber 410 is embedded in the corresponding first mounting groove 231 .

[0056] Thus, by providing the first mounting groove 231 on the plug-in end 23 , the first shock absorbing member 410 can be embedded in the corresponding first mounting groove 231 , thereby improving the installation stability of the first shock absorbing member 410 .

[0057] In some embodiments, a first clamping hole 2311 is defined on the wall of each first mounting slot 231 , and a first clamping column 4111 is defined on each first shock absorber 410 . Each first clamping column 4111 is clamped to the corresponding first clamping hole 2311 .

[0058] In this way, a first clamping hole 2311 is set on the wall of the first installation groove 231 and a first clamping column 4111 is set on the first shock absorber 410, so that the first shock absorber 410 is clamped in the first clamping hole 2311 through the first clamping column 4111 and fixed on the plug-in end 23 of the head 20.

[0059] In some embodiments, each of the first shock absorbing members 410 includes a first shock absorbing section 411 and a second shock absorbing section 412 connected to each other. When the plug-in end 23 is plugged into the plug-in slot 33, the first shock absorbing section 411 of each of the first shock absorbing members 410 abuts between the fan head 30 and the plug-in end 23 along the radial direction of the plug-in end 23, and the second shock absorbing section 412 of each of the first shock absorbing members 410 abuts between the fan head 30 and the plug-in end 23 along the axial direction of the plug-in end 23.

[0060] The number of the first clamping columns 4111 of each first shock absorber 410 is multiple, and the first shock absorbing section 411 and the second shock absorbing section 412 of each first shock absorber 410 are both provided with the first clamping columns 4111; the wall surface of each first mounting groove 231 is provided with multiple first clamping holes 2311; the first clamping columns 4111 are clamped in the corresponding first clamping holes 2311.

[0061] The first shock absorbing section 411 and the second shock absorbing section 412 may be perpendicular to each other.

[0062] In some embodiments, the first shock absorbing section 411 and the second shock absorbing section 412 can be configured to have a square, a circle, a polygon, or other shape.

[0063] Since the square shape can provide a larger contact area, the first shock-absorbing section 411 and the second shock-absorbing section 412 of the first shock-absorbing member 410 provided in the embodiment of the present application are both set to be square, so that the contact area between the first shock-absorbing member 410 and the rear mesh 34 of the fan head 30 is larger. When the vibration is transmitted from the fan head 30 along the machine head 20, the square-shaped shock-absorbing section between the fan head 30 and the machine head 20 can absorb the vibration more effectively, thereby reducing the vibration transmission between the fan head 30 and the machine head 20.

[0064] In addition, the first shock absorber 410 is configured to be a first shock absorber section 411 and a second shock absorber section 412 connected to each other, so that the first clamping columns 4111 of the first shock absorber section 411 and the second shock absorber section 412 are clamped to the corresponding first clamping holes 2311, thereby further improving the assembly stability of the first shock absorber 410 and preventing the first shock absorber 410 from loosening and falling off from the machine head 20.

[0065] In some embodiments, the first shock absorber 410 protrudes from the first mounting groove 231 along the radial direction of the plug end 23 ; the first shock absorber 410 protrudes from the first mounting groove 231 along the axial direction of the plug end 23 .

[0066] In this way, the first shock absorber 410 protrudes from the first mounting groove 231 along the radial direction of the plug-in end 23; the first shock absorber 410 protrudes from the first mounting groove 231 along the axial direction of the plug-in end 23, which can avoid the rear mesh 34 of the fan head 30 from directly contacting the plug-in end 23 of the machine head 20. When the vibration is transmitted from the fan head 30 along the machine head 20, the protruding part of the first shock absorber 410 can absorb the vibration, thereby reducing the vibration transmission between the rear mesh 34 of the fan head 30 and the machine head 20.

[0067] In some embodiments, the shock absorbing assembly 40 further includes a plurality of second shock absorbing members 420, which are arranged in sequence along the circumferential direction of the axis of the plug-in end 23; when the plug-in end 23 is plugged into the plug-in slot 33, the second shock absorbing members 420 abut between the fan head 30 and the plug-in end 23 along the axial direction of the plug-in end 23.

[0068] In this way, a plurality of second shock absorbers 420 are arranged in sequence along the circumferential direction of the axis of the plug end 23. When the plug end 23 is plugged into the plug slot 33, that is, the fan head 30 is connected to the machine head 20, the vibration transmission between the fan head 30 and the machine head 20 can be reduced by the plurality of second shock absorbers 420.

[0069] The second shock absorber 420 may have axial and radial shock absorbing functions. The second shock absorber 420 provided in the embodiment of the present application mainly provides axial and radial shock absorbing effects.

[0070] In some embodiments, the fan head 30 also includes a rear mesh 34, the plug-in slot 33 is arranged on the rear mesh 34, the rear mesh 34 is provided with a plurality of second mounting slots 341, the plug-in end 23 is provided with a plurality of third mounting slots 232, the plurality of second mounting slots 341 respectively correspond one-to-one with the plurality of third mounting slots 232, and the plurality of second shock absorbers 420 respectively correspond one-to-one with the plurality of third mounting slots 232. When the plug-in end 23 is plugged into the plug-in slot 33, one end of each second shock absorber 420 is embedded in the corresponding second mounting slot 341, and the other end of each second shock absorber 420 is embedded in the corresponding third mounting slot 232.

[0071] In some embodiments, the second shock absorber 420 can be configured in a cylindrical, square, or polygonal shape. Since the cylindrical second shock absorber 420 is easier to align during installation, the second shock absorber 420 in the embodiment provided in this application is configured in a cylindrical shape, which can improve the efficiency and accuracy of the fan 1 production and assembly.

[0072] In addition, the other end of the second shock absorber 420 is embedded in the second mounting groove 341 of the rear net 34, and the cylindrical surface is smooth without sharp edges. Therefore, setting the second shock absorber 420 into a cylindrical shape can reduce the friction between the second shock absorber 420 and the contact surface.

[0073] In some embodiments, the second mounting groove 341 is provided with a through hole 3411 and a plurality of ribs 3412 , and the plurality of ribs 3412 are arranged at intervals along the circumference of the second mounting groove 341 .

[0074] Since a sealed space is formed when the soft rubber and the hard rubber are combined, vacuum adsorption will be formed, that is, when the second shock absorber 420 is inserted into the second mounting groove 341 of the rear net 34, the second mounting groove 341 is easy to form a sealed space and then form vacuum adsorption, and vacuum adsorption will cause an adsorption force between the fan head 30 and the machine head 20. Therefore, by providing a through hole 3411 and multiple ribs 3412 in the second mounting groove 341, the formation of a sealed space in the second mounting groove 341 can be avoided, thereby reducing the probability of vacuum adsorption in the second mounting groove 341, thereby reducing the axial vibration transmission between the fan head 30 and the machine head 20.

[0075] In some embodiments, the length of each second shock absorber 420 is greater than the sum of the length of the corresponding second mounting groove 341 and the length of the corresponding third mounting groove 232 .

[0076] In this way, the length of the second shock absorber 420 is greater than the sum of the length of the corresponding second mounting groove 341 and the length of the corresponding third mounting groove 232, which can avoid the rear mesh 34 of the fan head 30 from directly contacting the plug-in end 23 of the machine head 20. When the vibration is transmitted from the fan head 30 along the machine head 20, the vibration is first transmitted to the excess part of the second shock absorber 420 between the fan head 30 and the machine head 20. Therefore, the excess part of the second shock absorber 420 can be used to absorb the vibration first, thereby reducing the vibration transmitted to the machine head 20.

[0077] In some embodiments, the fan head 30 includes a mesh shell 32 and fan blades 31, and the fan blades 31 are located in the mesh shell 32; the head 20 includes a head shell 24 and a motor 21, and the motor 21 is installed in the head shell 24, and the motor 21 has an output shaft 22; the fan 1 also includes a transmission module 10, and the transmission module 10 includes a transmission body 100 and a transmission shaft 200, and the transmission shaft 200 is rotatably passed through the transmission body 100, and the transmission body 100 is detachably connected to the mesh shell 32; when the transmission body 100 is connected to the mesh shell 32, one end of the transmission shaft 200 is passed through the fan blades 31; when the head shell 24 is connected to the mesh shell 32, the output shaft 22 is coupled to the other end of the transmission shaft 200.

[0078] In some embodiments, the shock absorbing assembly 40 further includes a third shock absorbing member 430 , which is wrapped around the outer surface of the transmission body 100 . When the transmission body 100 is connected to the mesh cover shell 32 , the third shock absorbing member 430 abuts between the transmission assembly and the mesh cover shell 32 .

[0079] In this way, by adding a third shock absorber wrapped around the outer surface of the transmission body 100 in the transmission module 10, and the third shock absorber abuts between the transmission body 100 and the mesh cover shell 32, directly contacting the transmission body 100 and the mesh cover shell 32, when the fan blades 31 vibrate due to imbalance, the third shock absorber can effectively absorb and dampen these vibrations, reduce the vibration amplitude, and prevent the vibration from being transmitted to the moving parts of the fan 1 such as the transmission body 100, thereby reducing the shaking and swaying of the transmission body 100 and the fan head 30 due to the influence of vibration, thereby reducing the noise generated by the fan 1 during operation.

[0080] Since silica gel and rubber materials have good shock-absorbing properties, the first shock-absorbing member, the second shock-absorbing member and the third shock-absorbing member can be silica gel shock-absorbing members or rubber shock-absorbing members.

[0081] In some embodiments, the handpiece further includes a clutch, and when the handpiece housing is connected to the mesh housing, the output shaft is coupled to the other end of the transmission shaft through the clutch.

[0082] The clutch can be made of soft materials, such as a silicone clutch or a rubber clutch.

[0083] A clutch 230 made of soft material is installed in the head housing 210, and the output shaft is coupled to the other end of the transmission shaft through the clutch, so that the clutch 230 serves as a transmission connection between the transmission shaft 130 and the output shaft 22, so that the output shaft 22 of the motor 21 transmits power to the transmission shaft 130 through the clutch 230, thereby driving the fan blades 120 to rotate.

[0084] Since the clutch 230 made of soft material has good buffering performance, it can absorb part of the impact energy when the motor 21 starts and stops, reduce rigid collisions, and thus reduce the noise generated by the entire fan 1, thereby improving the existing transmission system that uses a hard connection method, resulting in collisions between rigid connectors and the generation of abnormal impact noise.

[0085] Furthermore, since the clutch 230 is made of a soft material, the friction and wear between the clutch 230 and the transmission shaft 130 and the output shaft 22 can be reduced, thereby extending the service life of components such as the transmission shaft 130 and the output shaft 22.

[0086] In addition, after the entire fan head 10 is removed, since the motor 21 may still be rotating, a clutch 230 made of soft material is installed on the outer periphery of the output shaft 22 of the motor 21. Even if the user accidentally touches the clutch 230, the soft material can effectively prevent harm to the user.
