In addition, as shown in the cross-sectional view of FIG. 4, the tip of the protruding tube 34 protruding from the support member 3 to be coupled to each other while maintaining the contact surface of the bellows 9 coupled to the air pumping member 4 in a fixed state and It is configured to stably pump air by providing a locking step 341 and a locking groove 91 formed inside the bellows 9.

In addition, as shown in Figure 5a and 5b to cover the air inlet 31 formed on one side of the support member 3 to form a fixing projection (51) fitted into the fixing groove 35 formed in the support member (3) The cap 5 is provided to open the side. The cap 5 reduces the operation noise of the second damper 83 to open and close the air intake 31. In addition, the cap 5 is formed by fusion by ultrasonic welding in a state where the fixing protrusion 51 is fitted into the fixing groove 35 of the support member 3. As another example, the cap 5 may be formed on the outer upper end of the cap 5 by forming the protrusion 52 and the supporting member 3 by the second fixing table 37. After the projections 52 are fitted to be fixed, and made to be fixed to the second holder 37 as a conventional fixing screw.

In addition, as shown in FIGS. 1 and 4, the air passage 33 of the support member 3 is blocked at predetermined intervals to move the air in a zigzag form to the air supply port 38 formed at the tip of the air passage 33. In order to move and buffer the air in the vortex flow, a noise reduction tube 6 having integrally formed partitions 61 having a plurality of protruding jaws 62 on a vertical surface is provided. The noise reduction tube 6 is fused by ultrasonic waves using a thin protruding rib 63 formed at a portion in contact with the support member 3 to minimize noise of air moving between the perfect sealed structure and the partition wall 61. It becomes possible.

5A and 5B, a plurality of fixing pins 39 protrude from the support member 3 so as to determine a coupling position of the cap 5 and the noise reduction tube 6.

On the other hand, as shown in Figure 1 is mounted on all four sides of the lower case 1b of the lower case 1b is formed with a locking jaw (85a) in the upper and lower portions to absorb the vibration and the circular absorption portion 85b in the horizontal direction formed in the horizontal direction (85) ) To reduce noise and vibration. The vibration absorbing port 85 is formed of an elastic rubber material, so that the impact of the elastic suction force and vibration transmitted therein can be extended to the circular portion 85b in all directions to extend the life of the air pump 1 itself.

In addition, as shown in Figure 6, the support 41 of the air pumping member 4 is connected to the first holder 36 formed on the support member 3 so that the rubber ring 87 fitted to one end, which becomes an operation reference axis, is engaged. A coupling hole 361 is provided, and the opening 362 of the coupling hole 361 is configured to open in a size of 1/3 to 1/4 in the length of the circumferential surface of the coupling hole 361 so as to form a rubber ring like an imaginary line. Directly inserting the 87 in a crimped state and then rotating it provides a convenient assembly because it is fixed without being separated.

In the figure, reference numeral 86 is a stopper for closing the opening after coupling the second damper 83, 88 is a permanent magnet.

Next, the operation of the air pump for bedsores prevention mattress according to the present invention configured as described above will be described.

First, when power is supplied to the electric vibrator 2, magnetic force of +/- polarity is generated, and when the support 41 to which the permanent magnet 88 is attached by the magnetic force rotates repeatedly based on the rubber ring 87 The bellows 9 will start pumping. At this time, the air flowing into the air inlet 11 of the lower case (1b) is introduced into the guide protrusion (11b) forming the filter 81 and the air flow path to reduce the air noise, the filter 81 is supported Departure is prevented by a stopper 84 or stopper 84 'coupled to the tip of the tube 11a.

Then, the introduced air is moved to the air inlet 31 and the air outlet 32 of the support member (3). The first damper 82 and the second damper 83 open and close the passages of the air inlet 31 and the air outlet 32 during the movement of the air, and expose the first damper of the air inlet 31. The operating noise of 82 is reduced by the cap 5. At this time, the operation noise of the second damper 83 of the air outlet 32 is not transmitted to the outside by the closure of the stopper 86 and the bellows 9 but is transmitted to the air passage 33.

Air and noise moved to the air passage 33 flows into the noise reduction passage 6 and collides with the partition 61 and the protruding jaw 62 to reduce noise and to form a zigzag passage along the partition 61. The air is supplied to the mattress 10 through the air supply port 38 in a state in which the noise is minimized while the vortex moves.

On the other hand, the vibration and noise caused by the operation of the electric vibrator 2 and the air pumping member 4 are a plurality of square pyramid (12, 12 ') and triangular projection (13, 13') formed in the upper and lower cases (1a, 1b) ) To reduce noise and at the same time distribute the elastic suction force of the vibration absorbing port 85 itself mounted on the bottom of the lower case 1b and the impact transmitted to the circular portion 85b in all directions to provide a pleasant environment. Can be.

And the cap (5) and the noise reduction tube (6) can be conveniently positioned through the fixing pins 39 for positioning protruding from the support member (3), so that ultrasonic welding can be conveniently performed.
