[0032] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0036] The noise sources of existing inflation and deflation systems mainly include the following: 1. The noise generated when inflating the device to be inflated; 2. The noise generated by the air pump motor; 3. The impact sound caused by the magnetic field generated by the internal energized coil on the valve core; 4. The noise generated when deflation occurs. Among them, the noise generated by the air pump motor is the most obvious.

[0037] Based on the causes of the above noise sources, an embodiment of the present invention proposes an air filling and discharging structure 100, which can reduce or eliminate at least two of the above noise sources. Figure 1-Figure 7As shown, the inflation and deflation structure 100 includes an air pump 120, an air valve 130 and an air pump silencer assembly 140. The air valve 130 includes a first air port 133, a second air port 131 and a third air port 132. The air pump 120 is connected to the first air port 133 of the air valve 130. The air pump silencer assembly 140 is mounted on the outside of the air pump 120 to reduce the noise generated by the air pump 120. The inflation and deflation structure 100 also includes at least one of an inflation muffler 160, a deflation muffler 170, and an air valve muffler assembly 150. The inflation muffler 160 is disposed at the second air port 131 of the air valve 130 and is connectable to the device to be inflated. The deflation muffler 170 is disposed at the third air port 132 of the air valve 130. The second air port 131 and the third air port 132 are used for inflation and deflation, respectively. The inflation muffler 160 and the deflation muffler 170 can buffer the gas flow, reducing the inlet or outlet gas pressure, thereby reducing the inlet or outlet noise. The air valve muffler assembly 150 is mounted outside the air valve 130 to reduce the noise generated by the air valve 130.

[0038] The inflation and deflation structure 100 can effectively reduce at least two types of noise, including the noise generated by the air pump 120. During inflation, the second air port 131 of the air valve 130 communicates with the device to be inflated, and the gas enters the inflation muffler 160 through the second air port 131, thereby reducing the noise generated when inflating the device to be inflated. During deflation, the gas from the air valve 130 flows out through the third air port 132 and first passes through the deflation muffler 170, thereby reducing the noise generated when the device to be inflated is deflated.

[0039] In one embodiment, the inflation muffler 160 and the deflation muffler 170 are expansion mufflers, which are conventional and will not be described in detail herein. It should be emphasized that the inflation muffler 160 and the deflation muffler 170 are integrated into one body to save space.

[0040] In other embodiments, the charging muffler 160 and the deflation muffler 170 may also be energy absorbing mufflers, flow mufflers, etc.

[0041] refer to Figure 2 As shown, the air pump silencer assembly 140 includes a first silencer layer 141 and a second silencer layer 142, which are sequentially sleeved on the outside of the air pump 120 from the inside out. The first silencer layer 141 is a sponge layer, and the second silencer layer 142 is a metal layer. The metal used in the second silencer layer 142 has a certain thickness to isolate noise from the first accommodating cavity formed by the second silencer layer 142. The first silencer layer 141 is used to prevent the air pump 120 from colliding with the second silencer layer 142 during operation and generating noise.

[0042] According to the specific structure of the air pump 120 (the air pump 120 includes at least a pump body and a motor), the first sound-absorbing layer 141 further includes a pump body sleeve 1411, a motor sleeve 1412, and an end cover 1413. The pump body sleeve 1411 and the motor sleeve 1412 are both configured as cylindrical structures with openings at opposite ends. The pump body sleeve 1411 is sleeved on the pump body and abuts against the pump body, the motor sleeve 1412 is sleeved on the motor and abuts against the motor, and two end covers 1413 are provided. The two end covers 1413 are respectively disposed on opposite sides of the air pump 120 and bonded to the air pump 120. Of course, it is understandable that the shapes of the pump body sleeve 1411 and the motor sleeve 1412 are adapted to the shapes of the pump body and the motor, respectively. For example, the motor sleeve 1412 is configured as a square cylindrical structure, and the pump body sleeve 1411 is configured as a circular cylindrical structure. Furthermore, in order to enable the air pump 120 to be connected to the air valve 130 and an external control component for controlling the air pump 120 , a through hole is provided on the end cover 1413 for the air pipe and the cable to pass through.

[0043] More specifically, the sponge layer used in the first sound-absorbing layer 141 is rubber cotton, which has a good buffering effect, and the second sound-absorbing layer 142 is made of zinc alloy or steel.

[0044] In addition, the second sound-absorbing layer 142 is separately provided, including two sound-absorbing covers 1421, and the two sound-absorbing covers 1421 together enclose a first accommodating chamber, and the air pump 120 is located in the first accommodating chamber. Specifically, the two sound-absorbing covers 1421 have the same structure, and are both provided with a plug-in block 14211 and a plug-in hole 14212. The two sound-absorbing covers 1421 are connected by plugging in the plug-in block 14211 and the plug-in hole 14212. Compared with one sound-absorbing cover 1421 being provided with a plug-in block 14211 and the other sound-absorbing cover 1421 being provided with a plug-in hole 14212, the two sound-absorbing covers 1421 with the same structure can reduce the processing difficulty of the second sound-absorbing layer 142. Specifically, the sound-absorbing cover 1421 is provided as a semi-cylindrical hollow structure, and the second sound-absorbing layer 142 is provided with a cylindrical structure with both axial ends closed. Similar to the end cover 1413 , the silencer cover 1421 is also provided with a through hole for the cable and the air pipe to pass through on one side corresponding to the end cover 1413 .

[0045] In one embodiment, the air pump silencer assembly 140 further includes a third silencer layer 143 . The third silencer layer 143 is sleeved outside the second silencer layer 142 . The third silencer layer 143 is made of EVA cotton (a material copolymerized by ethylene and acetic acid).

[0046] Specifically, the third sound-absorbing layer 143 is integrally formed, and its shape matches that of the second sound-absorbing layer 142. For example, if the second sound-absorbing layer 142 is cylindrical, the third sound-absorbing layer 143 is also cylindrical. However, unlike the second sound-absorbing layer 142, the third sound-absorbing layer 143 is open at both axial ends to fit over the second sound-absorbing layer 142. In addition to providing noise reduction, the third sound-absorbing cotton also serves to secure the mating sound-absorbing cover 1421, preventing radial separation of the two covers 1421.

[0047] In one embodiment, the inflation and deflation structure also includes a shell 110, which further includes an upper shell and a lower shell. The upper shell and the lower shell together form a second accommodating chamber, and the air pump 120 and the air valve 130 are both located in the second accommodating chamber. The upper shell and / or the lower shell are provided with air vents connecting the inside and outside of the shell 110.

[0048] The motor of the air pump 120 inevitably generates vibrations when in operation. Therefore, the air pump silencer assembly 140 further includes an air pump vibration damping mount 144, which secures the air pump 120 to the housing 110. The air pump vibration damping mount 144 provides a vibration-damping elastic force to the air pump 120, thereby reducing noise generated by the vibration of the air pump 120 and the collision of the housing 110.

[0049] In one embodiment, the air pump vibration damping seat 144 is made of silicone. The air pump vibration damping seat 144 includes a first sleeve portion 1442 and a first fixing portion 1441. The first fixing portion 1441 is fixed to the bottom wall of the shell 110 by means including but not limited to bolt connection and bonding. The first sleeve portion 1442 and the first fixing portion 1441 are integrally formed and the shape is adapted to the shape of the third sound-absorbing layer 143. The first sleeve portion 1442 can be sleeved on the third sound-absorbing layer 143 and interference fit with the third sound-absorbing layer 143, thereby fixing the air pump 120 and the third sound-absorbing layer 143, and the installation is simple.

[0050] It should be emphasized that, since the air pump 120 is heavy, the bottom surface of the first fixing portion 1441 is completely in contact with the bottom wall of the housing 110 to avoid impacting the housing 110 .

[0051] refer to Figure 3 As shown, because the noise generated by the air valve 130 is weaker than the noise generated by the air pump 120, the air valve muffler assembly 150 includes a fourth muffler layer 151 that is sleeved onto the air valve 130. The fourth muffler layer 151 is configured as a cylindrical structure with a shape that matches the air pump 120. To facilitate sleeve installation on the air pump 120, the fourth muffler layer 151 has openings at both axial ends. Specifically, the fourth muffler layer 151 is also made of sponge, such as rubber cotton.

[0052] In one embodiment, the air valve silencer assembly 150 further includes an air valve vibration damping seat 152, which includes a second fixing portion 1521 and a second sleeve portion 1522. The second fixing portion 1521 is fixed to the bottom wall of the housing 110 by methods including, but not limited to, bolting or bonding. The second sleeve portion 1522 is integrally formed with the second fixing portion 1521 and its shape conforms to the shape of the fourth sound-absorbing layer 151. The second sleeve portion 1522 can be sleeved onto the fourth sound-absorbing layer 151 to achieve an interference fit with the fourth sound-absorbing layer 151, thereby securing the fourth sound-absorbing layer 151 and the air valve 130. Unlike the first fixing portion 1441, due to the relatively light weight of the air valve 130, the bottom surface of the second fixing portion 1521 abuts against the bottom wall of the housing 110, providing a buffer space for the air valve vibration damping seat 152, thereby achieving better cushioning and noise reduction effects.

[0053] refer to Figure 1 As shown, the inflation and deflation assembly also includes a control circuit board 180 and a battery 190 located in the shell 110. The battery 190 is used to provide power to the air valve 130 and the air pump 120. The control circuit board 180 is electrically connected to the air valve 130 and the air pump 120 to control the opening and closing of the air valve 130 and the air pump 120 and the speed of the air pump 120.

[0054] For example, the inflatable device connected to the inflation and deflation assembly is an airbag 600 in a breathing pillow. Control circuit board 180 controls the speed of air pump 120 to control the time it takes for the airbag 600 connected to the inflation and deflation assembly to fill. This controls the duration of breath-holding through the air pressure holding period, while the deflation interval of air valve 130 controls the deflation period. This, in turn, controls the overall inflation and deflation rhythm to guide breathing rhythm. The control principles and structure of control circuit board 180 for air valve 130 and air pump 120 are both prior art and will not be further described here.

[0055] refer to Figure 5-Figure 6 As shown, an embodiment of the present invention also provides a breathing pillow, including the inflation and deflation structure 100 described in any of the above embodiments, and also including an airbag 600 and a pillowcase 300. The airbag 600 and the inflation and deflation structure 100 are both located in the pillowcase 300. The airbag 600 is connected to the second air port 131 of the air valve 130 through an air pipe. The airbag 600 is located above the inflation and deflation structure 100 and is fixed on the inflation and deflation structure 100.

[0056] In one embodiment, to enhance the comfort of the breathing pillow, the breathing pillow further comprises an inner liner 200 disposed within the pillowcase 300. The airbag 600 and the inflation / deflation structure 100 are both located within the inner liner 200. To reduce the difficulty of placing the airbag 600 and the pillowcase 300 within the inner liner 200, the inner liner 200 is also provided in separate parts, including an inner liner upper mold 210 and an inner liner lower mold 220. The inner liner upper mold 210 and the inner liner lower mold 220 together enclose the airbag 600 and the inflation / deflation structure 100.

[0057] Obviously, the inner liner 200 is made of elastic material, such as sponge, to further improve the noise reduction effect. At least the shape of the inner liner 200 can be set according to the needs of consumers and is not specifically limited here.

[0058] In one embodiment, the breathing pillow further includes an inner cover 400, which is mounted on the inner liner 200 and located inside the pillowcase 300. The pillowcase 300 is provided with an openable and closable opening. When the pillowcase 300 needs to be cleaned, the inner cover 400 can be directly taken out from the opening.

[0059] In one embodiment, a heating plate 500 is further provided in the breathing pillow. The heating plate 500 is located on the outer surface of the lower inner shell 220 and is electrically connected to the control circuit board 180 to apply heat to the abdomen or other parts of the human body, thereby increasing the practicality of the breathing pillow.

[0060] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
