Detailed Description

The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention, please refer to fig. 1 to 4, and the embodiment of the present invention is as follows:

the utility model provides a central air conditioning ventilation is with novel muffler, includes box 1, and the both ends difference fixedly connected with intake stack 2 and air-out pipeline 3 of box 1 are provided with filter 4 on the intake stack 2, and aluminium foil abatvoix 5 has been laid to the inner wall of box 1, has seted up cavity 6 on the shell of box 1, and the inside of cavity 6 is provided with a plurality of bracing pieces 7.

Through above technical scheme, the staff connects this muffler in central air conditioning pipeline and central air conditioning air outlet department, when cold wind enters into box 1 inside from intake stack 2, the noise that the vibration produced when box 1 inside flows of air can be through the absorption of aluminium foil abatvoix 5 on the 1 inner wall of box, the effect of amortization is reached, and simultaneously, cavity 6 that the 1 shell of box was seted up makes and forms a buffer layer between box 1's shell and the inside cold air, the inner wall of box 1 has directly been conducted through the shell to the outside air temperature of box 1 has been avoided, can play energy-conserving heat retaining effect, bracing piece 7 can make box 1's shell structure more firm, be difficult to take place deformation.

Referring to fig. 3 and 4, a rectangular groove 8 is formed in one side of the air inlet duct 2, the filter plate 4 is inserted into the rectangular groove 8, a U-shaped through hole 41 is formed in one end of the filter plate 4, a baffle 42 is arranged at one end of each of two sides of the filter plate 4 close to the U-shaped through hole 41, a rectangular opening 44 is formed in the other end of the filter plate 4, a dust screen 45 is arranged inside the rectangular opening 44, and a magnet block 43 is fixedly connected to the surface of one side of the baffle 42 close to the rectangular opening 44.

Through the above technical scheme, filter 4 inserts the inside of locating rectangular channel 8, when needing to wash filter 4, the staff passes U type through-hole 41 with the finger, outwards exert oneself again, can take out filter 4, insert again after the clearance is accomplished in rectangular channel 8 can, insert the back, magnet piece 43 on the filter 4 is adsorbable on the outer wall of intake stack 2, prevent that the vibration that box 1 produced in the use from making filter 4 produce the displacement, during the use, the frequency of wasing dust screen 45 is higher, this setting is when dismantling filter 4, need not to dismantle the pipeline, it is convenient to dismantle, and avoided frequently dismantling the pipeline and cause the not hard up of pipeline, the service life thereof is prolonged.

Referring to fig. 2, the casing of the box 1 is made of a heat-insulating and purifying steel plate, the air inlet duct 2 and the air outlet duct 3 are made of steel plates, the heat-insulating and purifying steel plate can well perform the heat-insulating and purifying functions, so as to further enhance the heat-insulating effect of the box 1, and meanwhile, the air inlet duct 2 is made of steel plates, so that the magnet blocks 43 can be well adsorbed on the surface of the air inlet duct 2.
