[0015] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0017] The utility model provides a noise reduction burner, comprising a base 1, a fan 2 is movably connected in the base 1, a combustion head 3 is movably connected above the fan 2, an air inlet 201 is also installed on the fan 2, a positioning seat 4 is fixedly connected to the bottom wall of the base 1, the bottom of the fan 2 and the positioning seat 4 are mutually embedded, sound insulation cotton 101 is embedded in the base 1, a handle 202 is installed on the fan 2, the sound insulation cotton 101 occupies two-thirds of the thickness of the entire base 1, connecting rods 203 are symmetrically distributed at the bottom of the fan 2, a receiving groove 204 is provided in the positioning seat 4, the receiving groove 204 is connected to a plug rod 206 through a locking spring 205, the plug rod 206 and the connecting rod 203 are mutually embedded; the plug rod 206 and the connecting rod 203 are driven to be mutually embedded through the locking spring 205 structure;

[0018] When the noise reduction burner is actually used, the fan 2 in the burner is partially installed at the position of the positioning seat 4, and the connecting rod 203 at the bottom of the fan 2 is inserted into the position of the positioning seat 4. At this time, the locking spring 205 in the accommodating groove 204 drives the insertion rod 206 to pop out, so that the two are mutually locked with the insertion rod 206 inserted into the positioning seat 4. Before the fan 2 enters the positioning seat 4, the fixing plate 5 on the outside of the base 1 is set at a position away from the positioning seat 4 under the cooperation of the limit spring 503 and the pull ring 504. When the fan 2 enters the base 1 and is limited to the positioning seat 4, the staff manually releases the pull ring 504. At this time, the fixing plate 5 abuts against the outer wall of the fan 2 under the action of the limit spring 503, so that the fan 2 is in a relatively stable state in the base 1. Since the sound insulation cotton 101 structure is embedded in the base 1, the noise generated by the fan 2 in the base 1 can be effectively blocked. It absorbs sound at the same time, reduces the noise generated by the operation of the fan 2, and reduces the impact on the surrounding staff. By installing a base 1 structure on the outer side of the fan 2 structure of the burner, a sound insulation cotton 101 structure is embedded in the base 1, and a limit spring 503 is inserted in the base 1 to cooperate with the structure of the connecting rod 203, so that the fixing plate 5 is in contact with the outer wall of the fan 2 under the action of the limit spring 503, so that the fan 2 is in a clamped and fixed limited state in the base 1, and the generated noise can be timely absorbed by the sound insulation cotton 101, so as to achieve the effect of noise reduction. Compared with the conventional fan 2 structure in which the outer wall is not provided with a sound insulation device, the technical solution adopted by the utility model enables the noise generated by the fan 2 during operation to be absorbed in time, reduces the noise decibel, reduces the environmental impact on the surrounding staff, and the overall structure is compact and easy for the staff to install and maintain.

[0019] Example 1

[0020] like Figure 1As shown, the base 1 is symmetrically provided with fixing plates 5, the fixing plates 5 and the outer shape of the fan 2 are matched with each other, the left side of the fixing plate 5 is fixedly connected with a cross bar 501, the left end of the cross bar 501 is fixedly connected with a limiting plate 502, the limiting plate 502 is connected to the outer wall of the base 1 through a limiting spring 503, the limiting springs 503 are symmetrically distributed on both sides of the cross bar 501, and the left end of the limiting plate 502 is fixedly connected with a pull ring 504.

[0021] The effect achieved by the entire embodiment 1 is that, in use, before the fan 2 enters the positioning seat 4, the fixed plate 5 on the outside of the base 1 is set at a position away from the positioning seat 4 under the cooperation of the limit spring 503 and the pull ring 504. When the fan 2 enters the base 1 and is limited to the positioning seat 4, the staff manually releases the pull ring 504. At this time, the fixed plate 5 is in contact with the outer wall of the fan 2 under the action of the limit spring 503. The structural design of the pull ring 504 makes it easy for the staff to operate the limit plate 502 to drive the fixed plate 5 structure.

[0022] Working principle: Install the fan part in the burner at the positioning seat position, and insert the connecting rod at the bottom of the fan into the positioning seat position. At this time, the locking spring in the accommodating groove drives the insertion rod to pop out, so that the two are locked with each other with the insertion rod inserted into the positioning seat. Before the fan enters the positioning seat, the fixed plate on the outside of the base is set away from the positioning seat under the cooperation of the limit spring and the pull ring. When the fan enters the base and is limited to the positioning seat, the staff manually releases the pull ring. At this time, the fixed plate is in contact with the outer wall of the fan under the action of the limit spring, so that the fan is in a relatively stable state in the base. Since the base is embedded with a sound insulation cotton structure, the noise generated by the fan in the base can be absorbed in time, reducing the noise generated by the operation of the fan and reducing the impact on surrounding staff.
