DETAILED DESCRIPTION

[0027] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0028] like Figures 1 to 6 As shown, a blower sealing and shock absorbing structure comprises a blower 1 and a volute 2 connected to the blower 1, and a sealing and shock absorbing mechanism 3 is arranged between the blower 1 and the volute 2. The sealing and shock absorbing mechanism 3 is arranged at the connection position between the blower 1 and the volute 2, which can achieve good sound insulation and shock absorption effects.

[0029] The sealing and shock absorbing mechanism includes a first gasket 301, a second gasket 302, a sealing ring 303, a mounting platform 304 and a mounting hole 305. The mounting hole 305 is arranged on one side of the blower 1. There are three mounting platforms 304 and three mounting holes 305. The mounting platform 304 is arranged on the volute 2. The mounting platform 304 is connected to the mounting hole 305. A sealing ring 303 is arranged between the blower 1 and the volute 2. The first gasket 301 is arranged in the mounting hole 305. The second gasket 302 is arranged above the first gasket 301. In this embodiment, the first gasket 301 is made of rubber material, the second gasket 302 is made of plastic material, and the sealing ring 303 makes the contact position between the blower 1 and the volute 2 soft contact, which can play a good sound insulation and shock absorption effect. The first gasket 301 and the second gasket 302 are arranged in the mounting hole 305, and the mounting platform 304 and the mounting hole 305 cooperate with each other. The first gasket 301 and the second gasket 302 are arranged between the mounting platform 304 and the mounting hole 305, which can play a good shock absorption and sound insulation effect. When the mounting platform 304 is connected to the mounting hole 305, the structural setting of the first gasket 301, the second gasket 302 and the sealing ring 303 and the connection setting of the mounting platform 304 and the mounting hole 305 work together to make the sealing and shock absorption effect of the blower 1 and the volute 2 better. At the same time, the first gasket 301 is made of rubber material, and the second gasket 302 is made of plastic material, which also makes the sealing and shock absorption effect of the blower 1 and the volute 2 better.

[0030] The first washer 301 has a first annular groove 306 on its outer wall, and a circular boss 307 is provided in the mounting hole 305, and the first annular boss 307 cooperates with the first annular groove 306. The first annular boss 307 is stuck in the first annular groove 306, which can make the connection between the first washer 301 and the mounting hole 305 more stable, and can better achieve shock absorption and sound insulation effects.

[0031] The first stopper 4 is connected to one side of the mounting platform 304, the volute 2 is provided with a second annular groove 201, the first stopper 4 is located in the second annular groove 201, the first stopper 4 is provided with a first arc surface 401, the cross section of the first arc surface 401 is a quarter-circular structure, the first stopper 4 and the mounting platform 304 are an integrally formed structure, and the sealing ring 303 fits the first arc surface 401. The sealing ring 303 plays a supporting role, and the first arc surface 401 allows the sealing ring 303 to fit closely with the first stopper 4, and the shock absorption effect is better.

[0032] The second limiting blocks 5 are evenly distributed around the mounting platform 304. The mounting platform 304 and the second limiting blocks 5 are an integrally formed structure. When the mounting platform 304 and the mounting hole 305 are installed in coordination, the second limiting blocks 5 can abut against the first gasket 301 to play a supporting role.

[0033] The first limit block 4 and the second limit block 5 are square structures, and the first limit block 4 and the second limit block 5 are provided with a second curved surface 402 and a third curved surface 501 at one end away from the mounting platform 304, and the cross-sections of the second curved surface 402 and the third curved surface 501 are quarter-circular structures. Since the first limit block 4 and the second limit block 5 are both integrally formed structures, and the first limit block 4 and the second limit block 5 are set as a square structure, they can better play a supporting role, and the second curved surface 402 and the third curved surface 501 are set, so that a certain gap is left at the connection position when the mounting platform 304 is connected to the mounting hole 305, so as to avoid collision and noise when the blower 1 is slightly shaken.

[0034] A second annular boss 6 is provided on one side of the second gasket 302 close to the inner ring, and the outer side of the second annular boss 6 abuts against the inner side of the first gasket 301. When the mounting platform 304 is connected to the mounting hole 305, the top of the mounting platform 304 can abut against the second gasket 302, and the second gasket 302 can play a good shock absorption and sealing effect.

[0035] The first limit block 4 and the second limit block 5 are located in the mounting hole 305 and are in gap with the mounting hole 305. A gap is left between the first limit block 4 and the second limit block 5 and the mounting hole 305 to prevent the blower 1 from colliding with each other and generating noise when the blower 1 is slightly shaken.

[0036] At least two first limit blocks 4 are provided. Providing at least two first limit blocks 4 can provide a good support for the first gasket.

[0037] The mounting hole 305 is connected to the mounting platform 304 by means of a screw 7, and the screw 7 presses the second gasket 302. In the present embodiment, the first gasket 301 is made of rubber material, and the second gasket 302 is made of plastic material. This design enables good shock absorption and sound insulation effects between the blower 1 and the volute 2. At the same time, a certain gap is left between the screw 7 and the inner circle of the second gasket 302 to cope with the change in volume of the second gasket 302 caused by changes in the environment.

[0038] The upper end 304 of the mounting platform is provided with a fourth arc surface 8. The fourth arc surface 8 has a quarter circular cross section, so that there is a certain gap at the connection between the first gasket 301, the second gasket 302 and the mounting platform 304, which can reduce stress concentration caused by thermal expansion or contraction.

[0039] An installation method is implemented by a blower sealing and damping structure, comprising the following steps:

[0040] Step S1, placing the sealing ring 303 on the installation plane of the blower 1, and the sealing ring 303 is in contact with the first arc surface 401 of the first limiting block 4;

[0041] Step S2, placing the first gasket 301 in the mounting hole 305, so that the first annular groove 306 is engaged with the first annular boss 307;

[0042] Step S3, placing the second gasket 302 on the first gasket 301, so that the outer side of the second annular boss 6 abuts against the inner side of the first gasket 301;

[0043] Step S4 , aligning the mounting hole 305 with the mounting platform 304 , making the contact surface between the blower 1 and the volute 2 completely covered by the sealing ring 303 , and connecting the mounting platform 304 with the mounting hole 305 by means of screws 7 .

[0044] Functions and Effects of the Embodiments

[0045] The mounting platform 304 and the mounting hole 305 cooperate, and the first gasket 301 and the second gasket 302 are arranged between the mounting platform 304 and the mounting hole 305, which can achieve good shock absorption and sound insulation effects. The sealing ring 303 is arranged at the contact position between the blower 1 and the volute 2. The sealing ring 303 makes the contact position between the blower 1 and the volute 2 soft contact, which can achieve good sound insulation and shock absorption effects. Under the joint action of the structural setting of the first gasket 301, the second gasket 302 and the sealing ring 303 and the connection setting of the mounting platform 304 and the mounting hole 305, such a design enables the blower 1 and the volute 2 to have a good shock absorption and sound insulation effect; when the mounting platform 304 and the mounting hole 305 are connected, the first gasket 301 and the second limit block 5 are in close contact with the mounting platform 304, which can play a good shock absorption and sound insulation effect; the screw 7 presses the second gasket 302, so that the second gasket 302 is in close contact with the first gasket 301 and the mounting platform 304, which can have a good shock absorption and sound insulation effect. The design of the second arc surface 402, the third arc surface 501 and the fourth arc surface 5 can leave a certain gap between the mounting platform 304 and the mounting hole 305, which can avoid the noise caused by collision when the blower 1 is slightly shaken, and can also cope with the changes in the volume of parts caused by environmental changes.
