Two sets of limiting blocks are also slidably installed on the outer side of the intake pipe. A limiting ring groove is opened on the connecting pipe, and the limiting block on the outer side of the intake pipe is inserted into the limiting ring groove of the connecting pipe. A honeycomb sound-absorbing structure sleeve is fixedly installed on the intake pipe. Sound insulation cotton is fitted onto the outer end of the honeycomb sound-absorbing structure sleeve, and a protective sleeve is installed on the outer end of the sound insulation cotton. The protective sleeve is composed of a first sub-sleeve and a second sub-sleeve, and the first sub-sleeve and the second sub-sleeve are fitted onto the outer end of the intake pipe. A sealing gasket is installed on the inner end of the first sub-sleeve and the second sub-sleeve.

[0008] Furthermore, the outer end of the air intake pipe is provided with two sets of mounting grooves, and the upper and lower ends of the protective sleeve are respectively fixedly connected with mounting rings, and the mounting rings at the upper and lower ends of the protective sleeve are snapped onto the mounting grooves at the outer end of the air intake pipe.

[0009] Furthermore, a set of elastic elements are respectively sleeved on the connecting rod at the outer end of the limiting block, and the outer end of the elastic element is in contact with the inner end face of the support plate on the intake pipe.

[0010] Furthermore, a set of positioning blocks is fixedly installed at both ends of the first sub-sleeve, and a set of positioning grooves is opened at both ends of the second sub-sleeve, with the positioning blocks at both ends of the first sub-sleeve being inserted into the positioning grooves at both ends of the second sub-sleeve.

[0011] Furthermore, the outer end of the intake pipe is provided with a connecting groove, and a gasket is snapped onto the connecting groove at the outer end of the intake pipe, with the outer end of the gasket being sleeved onto the outer end of the connecting pipe.

[0012] Furthermore, the positioning block has a limiting hole, and a set of fixing screws are threaded onto both ends of the second sleeve, with the inner end of the fixing screws inserted into the limiting hole of the positioning block.

The first sleeve 301 and the second sleeve 302 are snapped onto the outer end of the intake pipe 1. A sealing gasket is installed on the inner end of the first sleeve 301 and the second sleeve 302.

[0030] like Figure 2 and Figure 3 As shown, two sets of support plates 102 are fixedly installed at both ends of the outer side of the intake pipe 1. Sliding holes are present on the support plates 102. Two sets of connecting rods 1031 are fixedly installed at the outer end of the limiting block 103, and the connecting rods 1031 at the outer end of the limiting block 103 are slidably installed on the sliding holes of the support plates 102 on the outer side of the intake pipe 1. A set of elastic elements 1032 are sleeved on the connecting rods 1031 at the outer end of the limiting block 103, and the outer end of the elastic element 1032 contacts the inner end face of the support plate 102 on the intake pipe 1. A connecting groove 101 is opened at the outer end of the intake pipe 1, and a gasket 4 is snapped onto the connecting groove 101 at the outer end of the intake pipe 1. The outer end of the gasket 4 is sleeved onto... Installed on the outer end of the connecting pipe 2; specifically, the connecting rod 1031 at the outer end of the limiting block 103 is slidably installed on the sliding hole of the outer support plate 102 of the air intake pipe 1. Pulling the limiting block 103 outward will snap the sleeve 4 into the connecting groove 101 at the outer end of the air intake pipe 1. The outer end of the sleeve 4 is sleeved and installed on the outer end of the connecting pipe 2. When the air intake pipe 1 moves to the fixed position, the limiting block 103 is released. Under the action of the elastic element 1032 on the connecting rod 1031, the limiting block 103 on the outer side of the air intake pipe 1 is inserted into the limiting ring groove 201 of the connecting pipe 2, thereby making the air intake pipe 1 of this device easy to disassemble and maintain quickly, and improving the maintenance efficiency of the device.

[0031] Example 2: Based on Example 1, as follows Figure 4 and Figure 5As shown, the outer end of the air intake pipe 1 is provided with two sets of mounting grooves 106. The upper and lower ends of the protective sleeve 3 are respectively fixedly connected with mounting rings 303, and the mounting rings 303 at the upper and lower ends of the protective sleeve 3 are snapped onto the mounting grooves 106 at the outer end of the air intake pipe 1. The two ends of the first sleeve 301 are respectively fixedly installed with a set of positioning blocks 3011. The two ends of the second sleeve 302 are respectively provided with a set of positioning grooves 3021, and the positioning blocks 3011 at the two ends of the first sleeve 301 are respectively inserted into the positioning grooves 3021 at the two ends of the second sleeve 302. The positioning blocks 3011 are provided with limit holes 3012. The two ends of the second sleeve 302 are respectively threaded with a set of fixing screws 3022, and the inner ends of the fixing screws 3022 are inserted into the limit holes 3012 of the positioning blocks 3011. Specifically, the mounting rings 303 at the upper and lower ends of the protective sleeve 3 are snapped onto the mounting groove 106 at the outer end of the air inlet pipe 1. The positioning blocks 3011 at both ends of the first sleeve 301 are respectively inserted into the positioning grooves 3021 at both ends of the second sleeve 302. A set of fixing screws 3022 are threaded onto both ends of the second sleeve 302. Tightening the fixing screws 3022 causes the inner end of the fixing screw 3022 to be inserted into the limiting hole 3012 of the positioning block 3011. This allows the protective sleeve 3 of this device to be quickly positioned and fixed onto the outer end of the air inlet pipe 1. Together with the honeycomb sound-absorbing structure sleeve 104 and the sound insulation cotton 105 on the air inlet pipe 1, it prevents dust from accumulating and blocking the honeycomb sound-absorbing structure sleeve 104, thus affecting the sound insulation effect of the device. This gives the device better sound insulation and dustproof effect.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In use, the limiting block 103 is pulled outward to engage the sleeve 4 onto the connecting groove 101 at the outer end of the air intake pipe 1. The outer end of the sleeve 4 is then fitted onto the outer end of the connecting pipe 2. When the air intake pipe 1 moves to a fixed position, the limiting block 103 is released. Under the action of the elastic element 1032 on the connecting rod 1031, the limiting block 103 on the outer side of the air intake pipe 1 is inserted into the limiting ring groove 201 of the connecting pipe 2. This allows the air intake pipe 1 of this device to be easily and quickly disassembled and maintained, improving the maintenance efficiency of the device. The two ends of the two-part sleeve 302 are respectively threaded with a set of fixing screws 3022. Tightening the fixing screws 3022 allows the inner end of the fixing screw 3022 to be inserted into the limiting hole 3012 of the positioning block 3011. This makes it easy to quickly position and fix the protective sleeve 3 of this device to the outer end of the air inlet pipe 1. Together with the honeycomb sound-absorbing structure sleeve 104 and sound insulation cotton 105 on the air inlet pipe 1, it prevents dust from accumulating and blocking the honeycomb sound-absorbing structure sleeve 104, which would affect the sound insulation effect of the device. This gives the device better sound insulation and dust prevention effects.
