detailed description

The invention will be further elaborated below with reference to the accompanying drawings.

As shown in FIGS. 1 to 5, a low-noise air pump device for a massage machine includes a housing, an air pump 4, and a gas valve 3. The housing includes a top case 1 and a bottom case 2, and the top case 1 and the bottom case 2 are fixedly connected by screws to form a hollow closed case, thereby On the one hand, the noise generated by the structure of the air pump 4, the air valve 3 and the like is provided with a soundproof effect; on the other hand, the low-noise air pump device can be modularized, the assembly is simple, the maintenance is convenient, and the manufacturing assembly is easier. A housing chamber 21 for mounting the air pump device is disposed in the housing, wherein the air pump 4 is installed in the accommodating chamber 21 and communicates with the air valve 3. An elastic device is mounted on the bottom wall of the accommodating cavity 21, and the elastic device supports the air pump 4 and is suspended in the accommodating cavity 21. When the air pump 4 is in operation, the vibration generated by the air pump 4 is absorbed by the elastic device on the one hand, and the elastic device can isolate the air pump 4 from the casing on the other hand, avoiding resonance between the air pump 4 and the casing, causing a large vibration of the massage machine. And noise, and thus avoid large noise caused by the user's boredom, affecting the physiotherapy effect.

As shown in FIG. 3 and FIG. 4, in order to better support the vibration generated by the air pump 4 and the buffer air pump 4, the elastic device in this embodiment adopts a conical spring 8, and the conical spring 8 is fastened to the bottom case 2. On the bottom, the specific installation process is to install the conical spring 8 on the mounting seat on the bottom case 2, and the limiting portion at the end of the conical spring 8 is caught in the limiting groove on the mounting seat to prevent the conical spring. 8 is rotated, the air pump 4 is placed above the conical spring 8, and the conical spring 8 is locked with the air pump 4 after passing through the conical spring 8 by screws. In the present embodiment, the number of the conical springs 8 is four, and is disposed at four corners of the lower end surface of the air pump 4, thereby stably mounting the air pump 4 on the bottom wall of the accommodating chamber 21. In addition, the tapered spring 8 used in the present embodiment has a spring force of about 0.4 KG when the compression amount is 6 mm, and a spring force of about 0.9 KG when the compression amount is 12 mm. Of course, in actual use, those skilled in the art can select the specifications of the conical spring 8 according to the different shapes, sizes and weights of the air pump 4.

In order to reduce the noise generated during gas transmission, a gas buffer 5 for storing a gas is provided between the air pump 4 and the gas valve 3, the gas buffer 5 includes a buffer chamber and an outer wall, and the air pump 4 passes through the first air tube 6 and the gas buffer The buffer chamber of 5 is in communication, and the gas damper 5 is in communication with the gas valve 3 through the second gas pipe 7. The support of the gas damper 5 by the first air pipe 6 and the second air pipe 7 ensures that the gas damper 5 is suspended in the casing, so that the vibration generated by the air pump 4 is prevented from being transmitted to the casing via the gas damper 5, Thereby, the vibration propagation path of the air pump 4 is cut off, so that the massage machine generates large vibration and noise, thereby avoiding the large noise causing the user's boredom and affecting the physiotherapy effect. Further, since the buffer chamber of the gas damper 5 has a large volume with respect to the first air tube 6, the gas pulsation generated when the air pump 4 is discontinuously discharged can be reduced, and the noise generated by the gas flow is greatly reduced. At the same time, the large volume of the buffer chamber of the gas damper 5 can also perform a storage action on the gas generated by the air pump 4, thereby ensuring sufficient and continuous gas supply.

In summary, the air pump 4 and the gas buffer 5 are suspended, that is, a double suspension structure, the air pump 4 is suspended in the accommodating cavity 21, and the gas damper 5 is suspended in the housing, thereby making the air pump 4 and the gas on the one hand. The vibration generated by the damper 5 can be isolated to prevent its vibration from being transmitted to the housing to cause the vibration machine to generate large vibration and noise; on the other hand, the air pump 4 and the gas damper 5 are suspended in the middle of the casing, so that The generated noise is transmitted through the air to the casing, and the ability to propagate sound is much smaller than the ability of the solid to propagate sound, which can be greatly reduced. The noise spreads, which in turn reduces noise.

As shown in FIGS. 2 and 3, a cushion 9 is provided between the side wall of the accommodating chamber 21 and the air pump 5. The cushion 9 is a rubber member. In the present embodiment, the cushion pad 9 has a card slot on the structure, and the card slot of the cushion pad 9 needs to be mounted on the side wall of the accommodating cavity 21 by card grounding. The number of the cushions 9 is four, and they are respectively mounted on the four front and rear side walls of the accommodating chamber 21, thereby defining the vibration amplitude of the air pump 5 in the horizontal direction. And the gap between the cushion 9 and the outer wall of the adjacent air pump 4 was set to 1 mm. In this way, it is possible to prevent the vibration amplitude from being excessively large in the horizontal direction when the air pump 4 vibrates, causing the massage machine to generate a large vibration and a high noise. Moreover, since the air pump 4 is suspended in the accommodating chamber 21, during the transportation of the air pump device or the massaging machine, the air pump 4 is liable to sway, and in severe cases, the air pump 4 may be damaged or the elastic device disposed at the bottom thereof. An irreversible deformation occurs. Therefore, by providing the buffer block 9, it is also possible to limit the air pump 4 during transportation to prevent damage of the air pump device. In addition, the inner side surface of the top case 1 may be provided with a rib that defines the upward vibration amplitude of the air pump 5, thereby taking a similar restriction action as the cushion pad 9.

As shown in FIGS. 3 and 5, the gas damper 5 has a cylindrical shape closed at both ends, and the two bottom walls of the gas damper 5 are connected to the side walls by curved curved surfaces having a large radius of curvature. Thereby, it can be ensured that the buffer chamber inside the gas damper 5 is relatively smooth, and the gas transmitted by the first gas pipe 6 does not generate large impact noise due to the presence of sharp corner portions in the buffer chamber. At the same time, it can be ensured that the overall shape of the gas buffer 5 is relatively smooth, and the noise of the gas buffer 5 against the casing during the vibration process is avoided. In addition, the large radius of curvature in this embodiment is a radius for making the gas buffer 5 as a whole smooth, and those skilled in the art can determine the specific value according to the size of the gas buffer 5 of different massage machines to make the gas The bumper 5 is as smooth as overall.

In order to increase the contact area, facilitate air release, and reduce noise, the side wall of the gas buffer 5 has a platform surface, and the second air pipe 7 is connected to the platform surface and communicates with the air outlet 52 provided on the platform surface. In order to facilitate the intake, the first air pipe 6 is connected to the curved surface on the opposite side of the deck surface and communicates with the air nozzle 51 provided on the curved surface, since the cross-sectional area of the curved surface of the gas buffer 5 is from the air nozzle 51. The edge begins to gradually become larger. Based on the Rafael principle, the gas can quickly enter the gas buffer 5, ensuring that the gas can be supplied to the massage airbag of the massage machine in time to squeeze the human body.

In order to prevent gas from entering and exiting the buffer chamber of the gas buffer 5, the gas buffer 5 is caused to expand and contract, and the air flow in the buffer chamber is unstable to cause a large noise. In the present embodiment, the outer wall of the gas buffer 5 is set to be hard. Outer wall.

In this embodiment, the first air pipe 6 is a rubber pipe. Since the softness of the first air pipe 6 is too small, the gas may cause expansion and contraction of the first air pipe 6 during the conveying process, so that the airflow in the first air pipe 6 is not Stable, causing loud noise. When the hardness of the first air pipe 6 is too large, the soft connection between the air pump 4 and the gas buffer 5 cannot be achieved, and the vibration generated by the air pump 4 cannot be buffered. Therefore, in this embodiment, The hardness of a gas pipe 6 is set to 45 degrees Shore (A), which can reduce the noise of gas transport in the first gas pipe 6 and can also effectively effect the vibration generated by the air pump 4. Buffer. Further, since the length of the first air pipe 6 is too short, the vibration generated by the air pump 4 cannot be buffered. When the length of the first air pipe 6 is too long, the gas transported at a high speed in the first air pipe 6 is liable to generate a large noise. Therefore, in the present embodiment, the length of the first air pipe 6 is set to 4.5 cm, so that the vibration generated by the gas in the first air pipe 6 for the air pump 4 can be effectively buffered and no large noise can be generated.

In the present embodiment, the second air pipe 7 is also a rubber pipe. Based on the same consideration as the hardness and length of the first air pipe 6, the hardness of the second air pipe 7 is set to shore (A) 45 degrees, and the length of the second air pipe 7 is set. It is 12 cm, so that the same buffer vibration and noise reduction effect as the first air pipe 6 are obtained. A rubber chuck 71 is disposed in a middle portion of the second air pipe 7, and the rubber chuck 71 has a card slot that can be snapped onto the rib of the casing. Since the rubber chuck 71 itself is also made of a rubber material, it is also possible to provide a certain buffering effect on the vibration of the gas damper 5.

The present invention also includes a low-noise massage machine comprising a gas massage device and a gas pump device for inflating the gas massage device, the air pump device being the aforementioned low-noise air pump device 100.

In other embodiments, in order to prevent the air pump from generating a large noise during the intake, the air inlet of the air pump may be equipped with a muffling pipe, and the muffling pipe includes a connecting portion connected to the air inlet and a reduced diameter air inlet portion. The gas is pumped from the outside to the intake portion from the air pump. Since the diameter of the inlet portion is relatively thin, the flow rate of the gas is large, and the connecting portion has a large diameter, which can provide a good buffer for the gas. To prevent noise from being generated by high-speed flowing gas.

In other embodiments, the top case and the bottom case may also be fixedly connected by welding, riveting or the like.

In other embodiments, the hardness of the first air pipe may be determined according to different shapes, weights, or sizes of the gas buffers, such as selecting shore (A) 40 degrees in a hardness range of 40 to 60 degrees of shore (A), Shore (A) 50 degrees, shore (A) 55 degrees, shore (A) 60 degrees and other hardness as the hardness of the first trachea. Similarly, the lengths of 3cm, 3.5cm, 4cm, 5cm, 5.5cm, 6cm, 6.5cm, 7cm, 7.5cm, 8cm are selected as the length of the first trachea in the length range of 3.0cm to 8.0cm; The hardness range of 40 to 60 degrees is selected as shore (A) 40 degrees, shore (A) 50 degrees, shore (A) 55 degrees, shore (A) 60 degrees hardness as the hardness of the second trachea; at 8.0 cm ~ The length of 8 cm, 8.5 cm, 9 cm, 9.5 cm, 10 cm, 10.5 cm, 11 cm, 11.5 cm, 12.5 cm, 13 cm, etc. is selected as the length of the second trachea in the length range of 13.0 cm.

In other embodiments, the gap between the cushion and the outer wall of the adjacent air pump may be determined according to different shapes, weights, or sizes of the air pump, such as 1.5 mm, 2 mm, and 2.5 mm in the range of the gap range of 1 mm to 3 mm. 3mm and other gaps.

The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
