Below in conjunction with accompanying drawing, the present invention is done to further detailed elaboration.

If Fig. 1 is to as shown in Fig. 5, a kind of low-noise air pump device for massager comprises housing, air pump 4 and air valve 3. Housing comprises top shell 1 and drain pan 2, and top shell 1 and drain pan 2 are fixed the housing that connects into hollow sealing by screw, thereby on the one hand the noise of the structure generations such as air pump 4, air valve 3 is played the effect of a sound insulation; Can also make on the other hand low-noise air pump apparatus module, make its assembling simple, easy to maintenance, be easier to manufacture assembling. In housing, be provided with the accommodating cavity 21 for air pump device is installed, wherein air pump 4 is arranged in accommodating cavity 21 and is communicated with air valve 3. On the diapire of accommodating cavity 21, elastic device is installed, elastic device supports air pump 4 and makes its floated being arranged in accommodating cavity 21. In the time that air pump 4 is worked, vibration by its generation can be absorbed by elastic device on the one hand, elastic device can be isolated air pump 4 and housing on the other hand, avoiding producing resonance between air pump 4 and housing makes massager produce larger vibration and noise, and then avoid large noise to cause user's boredom, affect physiotheraping effect.

As shown in Figure 3, Figure 4, the vibration producing in order to support preferably air pump 4 and buffering air pump 4, elastic device in the present embodiment adopts volute spring 8, and volute spring 8 is fastened on the bottom of drain pan 2, concrete installation process is, volute spring 8 is arranged on the mount pad on drain pan 2, and thereby the limiting section of volute spring 8 ends is stuck in the stopper slot on mount pad and prevents that volute spring 8 from rotating, air pump 4 is arranged on to the top of volute spring 8, passes after volute spring 8 volute spring 8 and air pump 4 are locked by screw. In the present embodiment, the quantity of volute spring 8 is 4, and point is located at four edges of air pump 4 lower surfaces, thereby air pump 4 is stably arranged on the diapire of accommodating cavity 21. In addition, the specification of the volute spring 8 adopting in the present embodiment is: in the time that its decrement is 6mm, its spring force is about 0.4KG, in the time that its decrement is 12mm, and the about 0.9KG of its spring force. Certainly, those skilled in the art can select according to different shapes, size and the weight of air pump 4 specification of volute spring 8 in actual use.

The noise producing when reducing gas transport, between described air pump 4 and air valve 3, be provided with the gas cushion 5 of stored-gas, gas cushion 5 comprises cushion chamber and outer wall, air pump 4 is communicated with the cushion chamber of gas cushion 5 by the first tracheae 6, and gas cushion 5 is communicated with by the second tracheae 7 and air valve 3. By the first tracheae 6 and the second supporting role of tracheae 7 to gas cushion 5, can ensure that gas cushion 5 is floated is arranged in housing, thereby avoid the vibration that air pump 4 produces to be delivered on housing via gas cushion 5, thereby cut off the Vibration propagation path of air pump 4, make massager produce larger vibration and noise, and then avoid large noise to cause user's boredom, affect physiotheraping effect. Because the cushion chamber of gas cushion 5 has larger volume with respect to the first tracheae 6, can reduce the air pulsing producing while giving vent to anger by air pump 4 is discontinuous again, reduce widely the noise that gas flow produces. Meanwhile, the gas that the large volume of the cushion chamber of gas cushion 5 can also produce air pump 4 carries out the effect of a storage, thereby ensures that gas is in liberal supply and continuous.

To sum up, the all floated settings of air pump 4 and gas cushion 5, it is dual suspension formula structure, in the floated installation accommodating cavity 21 of air pump 4, in the floated holder housing of gas cushion 5, thereby the vibration that on the one hand air pump 4 and gas cushion 5 is produced can be isolated, avoid its vibration to be delivered to housing and make massager produce larger vibration and noise; Air pump 4 and gas cushion 5 are floated being located in the middle of housing on the other hand, therefore in the communication process of the noise of its generation, be to arrive again housing by air, because the ability of air borne sound is far smaller than the soniferous ability of solid, can reduce greatly thus the communication effect of noise, and then reduce noise.

As shown in Figure 2 and Figure 3, between the sidewall of accommodating cavity 21 and air pump 5, be provided with cushion pad 9. Cushion pad 9 is rubber parts. In the present embodiment, in the structure of cushion pad 9, there is draw-in groove, when installation, only need the draw-in groove of cushion pad 9 to be arranged on the sidewall of accommodating cavity 21 by card earthing mode. The quantity of cushion pad 9 is four, is arranged on respectively on four sidewalls all around of accommodating cavity 21, thereby limits air pump 5 Oscillation Amplitude in the horizontal direction. And the gap between cushion pad 9 and adjacent air pump 4 outer walls is set to 1mm. So, can prevent from occurring that in the horizontal direction Oscillation Amplitude is excessive when air pump 4 from vibrating, make massager produce the problem of large vibration and high noisy. And because air pump 4 is floated being arranged in accommodating cavity 21, in the transportation of air pump device or massager, air pump 4 easily produces and rocks, when serious, even can cause air pump 4 to break or irreversible deformation occurs for elastic device that it is arranged on its bottom. Therefore can also be to 4 position-limiting actions of air pump in transportation by buffer stopper 9 is set, prevent that air pump device from damaging. In addition, the medial surface of top shell 1 can also be provided with and limit the upwards block reinforcement of Oscillation Amplitude of air pump 5, thereby gets the position-limiting action similar with cushion pad 9.

As shown in Fig. 3, Fig. 5, the cylindricality that gas cushion 5 is closed at both ends, is connected by the arc-shaped curved surface of larger radius of curvature between two diapires of gas cushion 5 and sidewall. By this, can ensure that the cushion chamber of inside of gas cushion 5 is comparatively smooth, the gas being transmitted by the first tracheae 6 can not produce larger impact noise because there is wedge angle position in cushion chamber. Can ensure the appearance integral smoother of gas cushion 5, avoid clashing into and generation noise with housing of gas cushion 5 simultaneously in vibration processes. In addition, larger radius of curvature in the present embodiment is a radius in order to make gas cushion 5 whole smooth, those skilled in the art can determine the numerical value that it is concrete according to the size of the gas cushion of different massagers 5, so that gas cushion 5 reaches whole smooth.

In order to increase contact area, to be easy to give vent to anger, reduce noise, on the sidewall of gas cushion 5, there is a flat surface, the second tracheae 7 is connected in this flat surface and with this outlet nozzle 52 being located in this flat surface and is communicated with. For ease of air inlet, the first tracheae 6 is connected on the curved surface of this flat surface opposite side and is communicated with this suction nozzle 51 being located on this curved surface, because the cross-sectional area of the curved surface of gas cushion 5 starts to become gradually large from the edge of suction nozzle 51, can enter fast gas cushion 5 based on your principle gaseous of daraf(reciprocal of farad), ensure that gas can be fed in the massage air bag of massager in time, human body is pushed to massage.

Cause gas cushion 5 for fear of the cushion chamber of gas input and output gas buffer 5 and produce expansion and shrink, thereby make the larger noise of the unstable initiation of air-flow in cushion chamber, in the present embodiment, the outer wall of gas cushion 5 is set to hard outer wall.

In the present embodiment, the first tracheae 6 is rubber tube, and because the pliability of the first tracheae 6 is when too small, gas can cause expansion and the contraction of the first tracheae 6 in the process of carrying, and makes the air-flow in the first tracheae 6 unstable, thereby causes large noise. And in the time that the hardness of the first tracheae 6 is excessive, cannot realize again being flexible coupling between air pump 4 and gas cushion 5, the vibration that can not produce air pump 4 has a reasonable cushioning effect, therefore in the present embodiment, the hardness of the first tracheae 6 is made as to shore (A) 45 degree, can makes the noise decline that gas carries in the first tracheae 6 and the vibration that can also produce air pump 4 effectively cushion. Because the length of the first tracheae 6 is when too short, the vibration that can not produce air pump 4 has a reasonable cushioning effect again. And when the first tracheae 6 length are when long, the gas of carrying in the first tracheae 6 high speeds easily produces again larger noise. Therefore in the present embodiment, the length of the first tracheae 6 is made as to 4.5cm, the vibration that air pump 4 is produced that can make gas carry in the first tracheae 6 effectively cushions and can not can produce larger noise.

In the present embodiment, the second tracheae 7 is also rubber tube, based on the identical consideration of hardness and the length of the first tracheae 6, the hardness of the second tracheae 7 is made as to shore (A) 45 degree, the length of the second tracheae 7 is made as 12cm, thereby gets the buffering vibration identical with the first tracheae 6 and reduce the effect of noise. And the middle part of the second tracheae 7 is provided with rubber dop 71, on rubber dop 71, there is the draw-in groove on the gusset that can be connected to housing. Because rubber dop 71 itself is also that elastomeric material is made, so also can play certain cushioning effect to the vibration of gas cushion 5.
