[0002] When the full premixed gas wall-mounted boiler is running, the DC turbine fan sucks in a large amount of air, and a large amount of air enters in a short time, generating flow noise, especially affecting the elderly, children and sleep at night. The existing wall-mounted boiler does not have a device to reduce the noise of these sounds, so a new silencer device came into being. Utility Model Content

[0003] To solve the problems raised in the above background technology. The utility model provides a full premixed condensing gas wall-mounted boiler intake silencer, comprising a silencer body, the side wall of the silencer body is provided with a mounting bracket installed on the wall-mounted boiler, the inner cavity of the silencer body is longitudinally fixed with two longitudinal baffles, and the inner cavity is transversely fixed with a transverse baffle, and the longitudinal baffles and the transverse baffles are cross-arranged.

[0004] As the air intake silencer of the fully premixed condensing gas wall-mounted boiler of the utility model, preferably, the longitudinal baffle and the transverse baffle divide the inner cavity of the silencer body into six cavity pipes.

[0005] As the air intake silencer of the fully premixed condensing gas wall-mounted boiler of the utility model, preferably, a plurality of small holes are provided on the longitudinal baffle and the transverse baffle.

[0006] As the air inlet silencer of the fully premixed condensing gas wall-mounted boiler of the utility model, preferably, the top of the silencer body is provided with an air inlet connected to the gas wall-mounted boiler through a connecting pipe.

[0007] As the air intake silencer of the fully premixed condensing gas wall-mounted boiler of the utility model, preferably, an air outlet is arranged at the bottom of the silencer body through a connecting pipe, and an air outlet is arranged on the air outlet.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] By installing a silencer between the air inlet and outlet of the gas wall-mounted boiler, after the air enters the pipe, the horizontal baffle and the vertical baffle divide the inner cavity of the silencer body into six chamber pipes. The partitions in the middle of each chamber are made of porous materials, which can allow noise to pass through the small holes and be trapped between these baffles. The movement space of the sound waves will be reduced, thereby generating friction to destroy this part of the sound waves and reduce noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0022] Example 1

[0023] like Figure 1 As shown;

[0024] The invention discloses an air intake silencer for a fully premixed condensing gas wall-mounted boiler, comprising a silencer body 1.

[0025] In the present implementation scheme: In order to solve the technical problems existing in the prior art, such as the above background technology disclosed that "when the fully premixed gas wall-mounted boiler is in operation, the DC turbine fan inhales a large amount of air, and a large amount of air enters in a short time to generate flow noise, especially at night affecting the elderly, children and sleep". Combined with actual use, this problem is obviously a real and difficult to solve problem. In view of this, in order to solve this technical problem, a fully premixed condensing gas wall-mounted boiler air intake silencer is provided.
