[0037] The present invention will be further described in detail below with reference to the accompanying drawings. The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent, so that those skilled in the art can implement it according to the description in the specification.

[0038] In the accompanying drawings, for clarity, the shapes and dimensions may be enlarged, and the same reference numerals will be used throughout the drawings to indicate the same or similar components.

[0039] In the following description, terms such as center, thickness, height, length, front, back, rear, left, right, top, bottom, upper, lower, etc. are defined with respect to the structures shown in the respective drawings. In particular, "height" corresponds to the dimension from top to bottom, "width" corresponds to the dimension from left to right, and "depth" corresponds to the dimension from front to back. They are relative concepts and may therefore change accordingly depending on their different positions and usage states. Therefore, these or other orientations should not be construed as restrictive terms.

[0040] Terms related to attachment, connection, etc. (e.g., "connect" and "attach") refer to the relationship in which these structures are directly or indirectly fixed or attached to each other through an intermediate structure, as well as a movable or rigid attachment or relationship, unless otherwise explicitly stated.

[0041] According to an embodiment of the present invention in combination Figure 1 , Figure 2 As shown, it can be seen that the sealing and shock-absorbing device includes:

[0042] An air flow generating device 20, which has an air inlet and an air outlet and is placed inside the bladeless fan for generating a high-speed air flow;

[0043] A diverter 10, which is located above the air outlet of the air flow generating device 20, and the air inlet of the diverter 10 has the same shape as the air outlet of the air flow generating device 20, and disperses and dredges the high-speed air flow;

[0044] Now referring to Figure 3 , Figure 4 and Figure 5 , it can be seen that a first sealing ring 310, which is located outside the air flow generating device 20 and the diverter 10;

[0045] A second sealing ring 320, which is located inside the air flow generating device 20 and the diverter 10;

[0046] A support member 40 for supporting the sealing and shock-absorbing device;

[0047] Wherein, the first sealing ring 310 is used to seal the gap between the outside of the air flow generating device 20 and the diverter 10, and the second sealing ring 320 is used to seal the gap between the inside of the air flow generating device 20 and the diverter 10; the support member 40 is connected to the first sealing ring 310 to fix the sealing and shock-absorbing device inside the bladeless fan.

[0048] The first sealing ring 310 and the second sealing ring 320 prevent the diverter 10 and the air flow generating device 20 from directly contacting each other. The first sealing ring 310 and the second sealing ring 320 block the vibration conduction of the air flow generating device 20, so that the diverter 10 can remain stable; the first sealing ring 310 and the second sealing ring 320 are preferably made of rubber.

[0049] The upper and lower ends of the first sealing ring 310 extend inward along the center of the first sealing ring 310 and do not contact each other, forming a claw structure 311. The cross-sectional areas of the upper and lower claws of the claw structure 311 gradually decrease along the extension direction, better sealing the gap outside the first sealing ring 310.

[0050] On the upper part of the outer side of the first sealing ring 310, there are T-shaped buckle structures 314 arranged in a circumferential array.

[0051] On the lower part of the outer side of the first sealing ring 310, a lower flange 312 is connected. There is a certain gap between the lower flange 312 and the first sealing ring 310, forming a groove 313.

[0052] Among them, the longitudinal part of the T-shaped buckle structure 314 is integrally formed with the first sealing ring 310. Designing the outer side of the first sealing ring 310 with a T-shaped buckle structure 314 on the upper part and a groove 313 on the lower part enables the cross combination of the first sealing ring 310 and the support member 40, ensuring the stability of the first sealing ring 310.

[0053] On the lower bottom surface of the diverter 10, there is a groove 110, which is adapted to the upper part of the second sealing ring 320.

[0054] At least two support feet 321 are provided on the lower part of the second sealing ring 320. The support feet 321 are connected to the upper end surface of the air flow generating device 20. The upper part of the second sealing ring 320 can ensure its tight connection with the diverter 10. Due to the vibration conduction of the air flow generating device 20, the diverter 10 generates up and down vibrations. Due to the setting of the support feet 321 on the lower part of the second sealing ring 320, the support feet 321 will deform due to the vibration, playing a certain role in alleviating the vibration and improving the service life of the diverter 10.

[0055] As Figure 6 shown in detail, an external flange 410 extends axially downward along the outer side of the support member 40.

[0056] An internal flange 420 extends axially downward along the inner side of the support member 40. The lower end of the internal flange 420 is connected to a support skirt 430.

[0057] An engaging groove 431 is formed between the upper part of the support skirt 430 and the inner side of the support member 40.

[0058] Among them, the engaging groove 431 is adapted to the T-shaped buckle structure 314 on the first sealing ring 310. The lower part of the support skirt 430 at least partially overlaps with the groove 313 of the first sealing ring 310. The upper end surface of the support member 40 is fixedly connected to the diverter 10, further stabilizing the diverter 10 and also enabling the diverter 10 to be tightly combined with the first sealing ring 310, the second sealing ring 320, and the air flow generating device 320, improving the sealing performance and shock absorption performance of the sealing and shock absorption device.

[0059] At least four buffer components 120 are provided at the central bottom of the shunt 10.

[0060] The buffer component 120 includes a buffer through hole 122 and a buffer rod 121;

[0061] Wherein, the buffer through hole 122 is integrally formed with the shunt 10.

[0062] The upper part of the buffer rod 121 is in the shape of an inverted hook, which can prevent the shunt 10 from slipping off due to the vibration of the air flow generating device 20 during operation;

[0063] The lower part of the buffer rod 121 is at least partially a spring, which further reduces the vibration of the shunt 10 and improves its service life;

[0064] Wherein, the upper part of the buffer rod 121 extends out of the buffer hole 122, and the lower part of the buffer rod 121 is connected to the upper end surface of the air flow generator 10.

[0065] In a specific embodiment, the first sealing ring 310, the second sealing ring 320 and the buffer component 120 can each play a shock-absorbing role and can be freely combined or used alone; the first sealing ring 310 and the second sealing ring 320 can respectively freely choose to closely contact the shunt 10 and the air flow generating device 20 on the upper and lower surfaces, or one side of the first sealing ring 310 and the second sealing ring 320 closely contacts the shunt 10 and the air flow generating device 20 for sealing; the first sealing ring 310 can also be directly connected to the bladeless fan and the shunt 10 without setting the support component 40.

[0066] The number of devices and the processing scale described here are used to simplify the description of the present invention. The application, modification and variation of the present invention will be obvious to those skilled in the art.

[0067] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those skilled in the art, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples here.
