Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a rear air outlet combination structure of a blowing and suction machine, comprising a blowing hood 1, an airflow hood 3 is arranged on the rear side of the blowing hood 1, a mounting plate 4 is fixedly connected to the bottom rear side of the airflow hood 3, a positioning rod 5 is rotatably connected to the inner side of the mounting plate 4, a first torsion spring 6 is fixedly connected to the outer side of the positioning rod 5, a top of the first torsion spring 6 is fixedly connected to the mounting plate 4, a clamping plate 7 is fixedly connected to the other end of the first torsion spring 6, a clamping block 8 is fixedly connected to the bottom of the airflow hood 3, the clamping block 8 is engaged with the clamping plate 7, a protective mechanism 2 is arranged on the outer side of the blowing hood 1, and the protective mechanism 2 is used to improve the connection strength between the blowing hood 1 and the airflow hood 3; a fixing ring 16 is fixedly connected to the front side of the outer wall of the blowing hood 1, and a plurality of reserved holes 17 are provided on the left and right sides of the outer wall of the fixing ring 16;

[0029] Specifically, the clamping plate 7 is engaged with the clamping block 8, thereby fixing the blow hood 1 and the airflow hood 3 together. When disassembly is required, the positioning rod 5 is rotated so that the clamping plate 7 overcomes the elastic potential energy of the first torsion spring 6, so that the clamping plate 7 and the clamping block 8 are no longer engaged, and the blow hood 1 and the airflow hood 3 can be separated. When installation is required, the two are aligned, the positioning rod 5 is loosened, and the elastic force of the first torsion spring 6 resets the clamping plate 7 and re-engages with the clamping block 8 to complete the fixation.

[0030] Reference Figure 2 and Figure 3 The protection mechanism 2 includes a protection frame 201, which is fixedly connected to the rear side of the outer wall of the blowing hood 1. The left and right sides of the outer wall of the protection frame 201 are rotatably connected with positioning blocks 202. The bottom of the positioning block 202 is threadedly connected to the blowing hood 1. The left and right sides of the outer wall of the protection frame 201 are fixedly connected with U-shaped blocks 203. The left and right sides of the rear end of the top of the outer wall of the blowing hood 1 are fixedly connected with positioning frames 204. A second torsion spring 205 is rotatably connected between the two adjacent positioning frames 204. The bottom of the second torsion spring 205 is fixedly connected to the protection frame 201.

[0031] Specifically, the protective frame 201 is fixedly connected to the rear side of the outer wall of the blow hood 1, providing a support frame for the entire protective mechanism 2, and the positioning blocks 202 on the left and right sides of the outer wall of the protective frame 201 can rotate relative to each other. When the protective frame 201 needs to be fixed, the positioning blocks 202 are rotated to the bottom and threadedly connected to the blow hood 1, thereby achieving a stable installation of the protective frame 201. The U-shaped blocks 203 on the left and right sides of the outer wall of the protective frame 201 play a role of auxiliary support and connection. The second torsion spring 205 is rotatably connected between the positioning frames 204 on the left and right sides of the rear end of the top of the outer wall of the blow hood 1, and the bottom of the second torsion spring 205 is fixedly connected to the protective frame 201. During operation, the second torsion spring 205 can provide a certain elastic buffering and reset effect, so that the protective frame 201 can reduce vibration when it is impacted by external force, and can return to its initial position after completing the work.

[0032] Reference Figure 1 , Figure 2 and Figure 3 , the bottom of the blow hood 1 is fixedly connected with rubber blocks 18 all around, and the outer sides of the multiple rubber blocks 18 are provided with mounting holes 19; the right side of the outer wall of the blow hood 1 is fixedly connected with a connecting plate 14, and the front side of the connecting plate 14 is fixedly connected with a connecting cover 15; the left and right sides of the top of the airflow hood 3 are fixedly connected with fixed blocks 9, and the inner side of the fixed block 9 is provided with a handle 10, and the inner side of the fixed block 9 is threadedly connected with a screw 11, and the screw 11 is threadedly connected to the handle 10; the rear side of the blow hood 1 is fixedly connected with a buckle 13, and the outer side of the buckle 13 is rotatably connected with a protective cover 12;

[0033] Specifically, the rubber block 18 and the mounting hole 19 thereon can facilitate the fixation of the device to other equipment, and the elasticity of the rubber block 18 can reduce the wear during fixation. The handle 10 can be fixed by the threaded connection between the screw 11 and the handle 10 and the fixing block 9, so that the device can be carried and held by the handle 10. The buckle 13 can facilitate the fixation of additional equipment on the outside of the device, and the shield 12 thereon can protect the buckle 13 when not in use.

[0034] Working principle: before using the device, firstly, the blowing hood 1 and the airflow hood 3 are fixed together by engaging the clamping plate 7 with the clamping block 8. When disassembling, the positioning rod 5 is rotated to make the clamping plate 7 overcome the elastic force of the first torsion spring 6, and the clamping plate 7 and the clamping block 8 are released to separate the blowing hood 1 and the airflow hood 3. When installing, align the two, release the positioning rod 5, and the elastic force of the first torsion spring 6 resets the clamping plate 7, and engages with the clamping block 8 again to complete the fixation;

[0035] The protective frame 201 is fixed on the outside of the blow hood 1 to provide a supporting frame. The positioning block 202 is rotated to the bottom of the blow hood 1 and fixed with threads to ensure that the protective frame 201 is firmly installed. The U-shaped block 203 assists in supporting the connection. The positioning frame 204 is connected to the second torsion spring 205 to provide elastic buffering and reset functions to reduce vibration and ensure that the protective frame 201 can be reset to its initial position after being subjected to force.
