The silencing assembly 7 can effectively silence the noise generated by the blower 2 when in use, thereby avoiding the noise from affecting the surrounding environment.

[0023] Example 2

[0024] In this embodiment, reference Figure 1-5A blower 2 is installed inside the device body 1, a fixing seat 3 is fixedly installed at the bottom of the blower 2, an air inlet pipe 4 is fixedly installed on the front side wall of the blower 2, the air inlet pipe 4 is connected to the inside of the blower 2, a filter 5 is fixedly installed on the front end of the inner wall of the air inlet pipe 4, and an air outlet pipe 6 is fixedly installed on the lower end of the outer wall of the blower 2. The blower 2 can effectively inhale air through the air inlet pipe 4 and discharge it through the air outlet pipe 6. At the same time, the filter 5 installed on the inner wall of the air inlet pipe 4 can effectively filter the impurities contained in the air to avoid entering the inside of the blower 2 and causing erosion and damage. The end of the air outlet pipe 6 away from the blower 2 is fixedly installed by bolts A connecting pipe mouth 8, a side wall of one end of the connecting pipe mouth 8 away from the air outlet pipe 6 is fixedly connected to the silencer assembly 7 by bolts, and the silencer assembly 7 is communicated with the blower 2 through the connecting pipe mouth 8, so that the silencer assembly 7 can be effectively installed and fixed, and at the same time, the blower 2 can perform excellent silencing treatment on the noise generated by the silencer assembly 7 when in use. The sound insulation layer 72 adopts steel plate material, which can effectively separate the noise energy and achieve the effect of reducing the noise. The silencer board 73 adopts polyurethane foam plastic, so that the silencer board 73 can effectively isolate and absorb the noise energy after the style, thereby weakening the noise.

[0025] The working principle of the device is as follows: first, the blower 2 is installed in a suitable position through the fixing base 3 to ensure the stability of the blower 2 when in use. At the same time, the blower 2 inhales air through the air inlet pipe 4 and then passes through the air outlet pipe 6. During the process, the impurities in the air can be filtered through the filter 5 to prevent them from entering the blower 2 and causing erosion and damage; at the same time, when the blower 2 discharges the air through the air outlet pipe 6, a great noise will be generated. This is because the silencer component 7 is connected to the blower 2 through the connecting pipe mouth 8, so that the silencer shell 71 limits the propagation of noise, and at the same time, the noise energy is effectively separated by the sound insulation layer 72 installed inside it, thereby effectively weakening the noise, and then the sound insulation board 73 is used to effectively soundproof and silence the separated noise energy, which can greatly weaken the noise and prevent the blower 2 from generating a large noise when in use, thereby effectively avoiding noise pollution.
