Description

Technical Field

[0001] The utility model relates to the technical field of blower silencing, in particular to a blower. Background Art

[0002] Centrifugal blowers are based on the principle of converting kinetic energy into potential energy. They use a high-speed rotating impeller to accelerate the gas, then slow it down and change the flow direction, converting kinetic energy into potential energy (pressure).

[0003] Existing blowers usually install a silencer between the air filter and the screw device due to the high noise during operation, so that the air flows through a certain damping space to reduce the noise. The silencer installed in the current blower is usually an integral structure, which has a high production cost. In addition, when assembling the silencer with the screw device and the filter assembly, the installation positions of the screw device and the filter assembly need to be taken into account at the same time, making the assembly of the silencer more complicated.

The air outlet 14 is arranged on the side of the cabinet 11, and a reflux baffle 141 is provided on the air outlet 14 to prevent air from flowing back from the air outlet 14 into the cabinet 11. The screw device 15 is disposed in the cabinet 11. An impeller is disposed in the screw device 15. When the impeller rotates, air can flow from the air inlet 13 into the air channel and then be discharged from the air outlet 14. The drive device 16 is disposed in the cabinet 11. The drive device 16 is connected to the screw device 15. The connection method can be interference fit, bolt connection or other connection methods. The drive device 16 is rotatably connected to the impeller and can drive the impeller to rotate. In order to clearly illustrate the technical solution of the utility model, the following is also defined: Figure 1 Front, back, left, right, top and bottom shown.

[0017] like Figure 2 As shown, the blower also includes a filter assembly 17 and a silencer assembly 18. The filter assembly 17 is arranged in the cabinet 11, and the filter assembly 17 is connected to the top surface of the cabinet 11. Specifically, a mounting frame 111 is provided at the lower end of the top surface of the cabinet 11, and the filter assembly 17 is at least partially arranged in the mounting frame 111 to be connected to the top surface of the cabinet 11. This arrangement facilitates the disassembly, cleaning and maintenance of the filter assembly 17. The silencer assembly 18 is arranged in the cabinet 11, and the silencer assembly 18 includes a first box body 181 and a second box body 182. The first box body 181 and the second box body 182 are connected, and the connection method can be set to bolt connection, clamping or other connection methods. The first box body 181 is connected to the filter assembly 17 and the top surface of the cabinet 11. The second box body 182 is connected to the screw device 15 and the top surface of the cabinet 11. Through the above arrangement, when assembling the silencer assembly 18, the first box body 181 can be connected to the filter assembly 17 first, and then to the cabinet 11; the second box body 182 can be connected to the screw device 15 first, and then to the cabinet 11, and finally the first box body 181 and the second box body 182 can be docked and connected. During the entire assembly process, there is no need to consider the docking problem between the silencer assembly 18 and the filter assembly 17 and the screw device 15, thereby making the assembly of the blower more convenient. In addition, the silencer assembly 18 is divided into the first box body 181 and the second box body 182, which reduces the rigidity requirement of the material of the silencer assembly 18 and improves the structural stability of the silencer assembly 18.

[0018] like Figure 2 and Figure 3 As shown, the muffler assembly 18 extends substantially in the left-right direction. In the cabinet 11, a second box 182, a first box 181 and a filter assembly 17 are sequentially arranged from left to right. The top surface of the cabinet 11 is provided with a first top cover 112 and a second top cover 113. The lower end of the first top cover 112 is provided with a first connecting portion 1121. The top surface of the first box 181 is provided with a first connecting member 1811, and the first connecting member 1811 is arranged at both ends of the first connecting portion 1121 and connected to the first connecting portion 1121, so as to fix the first box 181 to the first top cover 112. Among them, the connection method between the first connecting portion 1121 and the first connecting member 1811 can be set as a bolt connection to improve the portability and stability of the assembly of the first box 181. Similarly, the lower end of the second top cover 113 is provided with a second connecting portion 1131. Among them, the second top cover 113 can be arranged on the front side of the radiator 12 to save assembly space.

The silencer channel tube 151 passes through the through hole 1822 and is at least partially disposed in the second box body 182 to prevent the silencer channel tube 151 from being separated from the second box body 182. The silencer channel tube 151 is tightly fitted around the inner wall of the through hole 1822 to prevent gas from leaking from the second box body 182 into the cabinet body 11.

[0020] like Figure 3 As shown, a plurality of staggered silencers 183 are provided on the inner top wall and the inner bottom wall of the silencer assembly 18. The silencer assembly 18 forms a labyrinth passage inside through the silencers 183 to increase the damping space through which the gas flows from the filter assembly 17 to the screw device 15, thereby reducing the gas energy as much as possible and reducing the noise. Specifically, the silencer 183 includes silencer cotton 1831 and a fixing frame 1832. The silencer cotton 1831 can reduce the energy of the contacted gas to improve the silencer effect of the silencer assembly 18. The fixing frame 1832 is connected to the inner top wall and the inner bottom wall of the silencer assembly 18, and the silencer cotton 1831 is at least partially arranged in the fixing frame 1832 so that the silencer cotton 1831 can be disassembled and assembled.

[0021] In summary, the present application provides a blower, during assembly, the first box 181 is connected to the filter assembly 17; the second box 182 is connected to the screw device 15, and then the first box 181 is connected to the second box 182 and respectively connected to the cabinet 11, which reduces the difficulty of assembling the silencer assembly 18 and improves the convenience of assembly. At the same time, the silencer assembly 18 is divided into the first box 181 and the second box 182, which reduces the rigidity requirement of the silencer assembly 18 for the material, reduces the production cost of the blower, and improves the structural stability of the silencer assembly 18.
