Description

Technical Field

[0001] The present application relates to the technical field of air pumps, and in particular to an inflation mechanism and massage equipment. Background Art

[0002] Air pumps mainly include manual (or foot-operated) air pumps and electric air pumps. Electric air pumps use an engine to drive the piston to move back and forth to inhale and inflate air, so as to expel gas from a closed space or inflate a closed space. During the operation of the air pump, vibrations are easily generated, causing the air pump to collide with the installation cavity and generate loud noise. In related technologies, elastic materials are mostly placed between the air pump and the installation cavity to cushion the vibration of the air pump. Although this method can achieve a certain shock-absorbing and noise-reducing effect, it is still not ideal. Utility Model Content

[0003] The embodiments of the present application disclose an inflation mechanism and a massage device, which can perform multi-level shock absorption on a driving element and reduce the operating noise of the driving element, thereby improving the shock absorption and noise reduction effects of the inflation mechanism and the massage device.

[0004] To achieve the above objectives, in a first aspect, embodiments of the present application disclose an inflation mechanism, comprising:

[0005] a first housing, the first housing having a first installation space, the first housing being provided with a support portion, the support portion being located in the first installation space;

[0006] a driving element, the driving element being disposed in the first installation space;

[0007] a first shock-absorbing component, the first shock-absorbing component comprising a sleeve portion and a cantilever portion, the sleeve portion being configured to be sleeved on the driving element, the cantilever portion being provided on the sleeve portion, and the cantilever portion being configured to be connected to the support portion so that the driving element is suspended in the first installation space; and

[0008] A second shock absorbing member is connected to the cantilever portion and the supporting portion.

[0009] The inflation mechanism provided in the embodiments of the present application utilizes a support portion and a cantilever portion to suspend the drive element in the first mounting space within the first housing. A second damping component is provided at the connection between the support portion and the cantilever portion. Thus, during operation of the drive element, vibrations are first partially absorbed by the sleeve portion, then further absorbed by the cantilever portion as they are transmitted to the first housing. Finally, the second damping component provides secondary damping, thereby reducing the operating noise of the drive element.

[0010] In addition, the sleeve portion is sleeved on the driving element. When the driving element collides with the first shell due to excessive vibration of itself or external force, the sleeve portion can also perform shock absorption and buffering, thereby effectively protecting the driving element and preventing the driving element from collision damage or damage that causes it to be unable to operate.

[0011] As an optional embodiment, the cantilever portion extends along a first direction, and the second shock absorbing component is located between the cantilever portion and the support portion along a second direction.

[0012] The second direction intersects with the first direction.

[0013] The cantilever portion and the second shock-absorbing component are respectively arranged along the first direction and the second direction, so that the cantilever portion and the second shock-absorbing component can better absorb vibrations in different directions generated by the operation of the driving element, further improving the effect of shock absorption and noise reduction.

[0014] As an optional embodiment, one of the support portion and the cantilever portion is provided with a protrusion, and the other is provided with a connecting hole. The protrusion is inserted into the connecting hole, and the second shock-absorbing component is at least partially located in the connecting hole. The cooperation between the protrusion and the connecting hole of the support portion and the cantilever portion secures the first shock-absorbing component and the driving element, thus further stabilizing the shock-absorbing structure of the inflation mechanism. The protrusion also secures the second shock-absorbing component and guides its compression and extension.

[0015] As an optional embodiment, the cantilever portion includes an extension portion and a connecting portion. The extension portion is provided on the sleeve portion and is hollowed out. The connecting portion is connected to the side of the extension portion facing away from the sleeve portion. One of the connecting portion and the supporting portion is provided with the protrusion, and the other is provided with the connecting hole. The hollowed-out design of the extension portion can reduce the thickness of the extension portion, making it easier to deform and further improving the shock absorption effect.

[0016] As an optional embodiment, the cantilever portion further includes a reinforcement portion, located in a hollowed-out portion of the extension portion and connected to the connecting portion and the sleeve portion. The reinforcement portion connects the sleeve portion and the connecting portion, and the reinforcement portion cooperates with the extension portion to achieve a multi-point connection between the sleeve portion and the connecting portion, thereby ensuring a more stable connection, greater structural stability of the cantilever portion, and a more secure connection.

[0017] As an optional embodiment, the sleeve portion, the extension portion, the connecting portion, and the reinforcement portion are integrally formed. By integrally forming the sleeve portion, the extension portion, the connecting portion, and the reinforcement portion, the overall stability of the first shock-absorbing component is enhanced. Furthermore, the assembly steps of the first shock-absorbing component are simplified, reducing the complexity of the inflation mechanism assembly and making installation more convenient and quick.

[0018] As an optional embodiment, the first housing includes a first sub-shell and a second sub-shell, the first sub-shell is connected to the second sub-shell, the first sub-shell is provided with a first sub-support portion, the second sub-shell is provided with a second sub-support portion, and the cantilever portion is connected between the first sub-support portion and the second sub-support portion;

[0019] One end of the second shock absorbing component is connected to the cantilever portion, and the other end of the second shock absorbing component is connected to the first sub-support portion or the second sub-support portion.

[0020] In this way, the driving element is suspended in the air by connecting the cantilever part with the first sub-support part and the second sub-support part, and the first sub-support part and the second sub-support part are engaged with each other by connecting the first sub-shell and the second sub-shell, so that the cantilever part is firmly fixed to improve the reliability of the suspension of the driving element; at the same time, the second shock-absorbing component is connected with the first sub-support part and the second sub-support part, and the second shock-absorbing component is clamped by the first sub-support part and the second sub-support part, thereby achieving the fixation of the second shock-absorbing component.

[0021] As an optional embodiment, the first shell is provided with a plurality of the support portions, and the plurality of cantilever portions are respectively connected to a corresponding support portion, and at least one of the cantilever portions and the support portion is connected to the second shock-absorbing component. Through the corresponding connection of the multiple support portions and the multiple cantilever portions, the connection between the first shock-absorbing component and the first shell is more secure, thereby making the fixation of the driving element more stable; at the same time, the cooperation of the multiple cantilever portions can withstand the greater vibration force of the driving element, further improving the shock-absorbing and noise-reducing effect of the inflation mechanism; in addition, the second shock-absorbing component is connected to at least one cantilever portion and the support portion, which can reduce the number of parts of the inflation mechanism while maintaining the secondary shock-absorbing effect of the inflation mechanism, making assembly easier and reducing production costs.

[0022] As an optional embodiment, the inflator further includes a sound-absorbing assembly comprising a second shell and sound-absorbing cotton. The second shell has a second mounting space, the first shell is disposed within the second mounting space, and the sound-absorbing cotton is disposed between the first and second shells. By disposing the sound-absorbing cotton between the first and second shells, the operating noise of the drive element can be absorbed by the cotton. Furthermore, by providing a single set of sound-absorbing cotton, the production cost of the inflator can be reduced while still absorbing the operating noise of the inflator.

[0023] As an optional embodiment, the sound-absorbing cotton is connected to the outer wall surface of the first shell;

[0024] and / or,

[0025] The sound-absorbing cotton is connected to the inner wall surface of the second shell.

[0026] In this way, when the sound-absorbing cotton is connected to both the first shell and the second shell, the working noise of the driving element can be absorbed by the sound-absorbing cotton; at the same time, the first shell can be installed and fixed by the sound-absorbing cotton, without the need to set up additional components to fix the first shell in the second installation space, making the structure of the inflation mechanism more compact; and the sound-absorbing cotton can play a shock-absorbing role on the first shell, further improving the shock-absorbing and noise reduction effect.

[0027] As an optional embodiment, the sound-absorbing components are provided in multiple groups, each of which is sequentially wrapped around the outer periphery of the first shell. In this way, the operating noise of the inflation mechanism can be minimized, enabling the inflation mechanism to meet higher noise control requirements in environments.

[0028] As an optional embodiment, the inflation mechanism further includes a gas tank, which is disposed in the first installation space and connected to the gas outlet of the driving element. This connection between the gas tank and the gas outlet of the driving element compresses and stores the gas ejected by the driving element, mitigating pressure fluctuations in the output gas. Furthermore, by locating the gas tank in the first installation space, the sound-absorbing cotton absorbs airflow noise generated when gas is transferred to the gas tank.

[0029] As an optional embodiment, the gas tank and the driving element are arranged in sequence along the axis of the driving element. This arrangement can reduce the length of the gas transmission pipeline, simplify the arrangement of the gas tank and the driving element, and make the assembly of the inflation mechanism more convenient.

[0030] In a second aspect, an embodiment of the present application further discloses a massage device comprising the inflation mechanism as described in the first aspect. The massage device having the inflation mechanism also has the effect of reducing vibration and noise.

[0031] Compared with the prior art, the present invention has the following advantages:

[0032] The inflation mechanism and massage device provided in the embodiment of the present application are characterized in that the inflation mechanism is provided with a support portion on the first shell, and the driving element is sleeved in the sleeve portion of the first shock-absorbing component, and the cantilever portion of the first shock-absorbing component is connected to the support portion so that the driving element is suspended in the first shell, and a second shock-absorbing component is provided at the connection between the support portion and the cantilever portion. Thus, during the operation of the driving element, the vibration of the driving element is first partially absorbed by the sleeve portion, and then further absorbed by the cantilever portion during the process of being transmitted to the first shell through the cantilever portion, and finally secondary shock absorption is performed by the second shock-absorbing component, thereby reducing the working noise of the driving element. It can be seen that the use of the inflation mechanism of the present application can achieve multi-stage shock absorption of the driving element, which is conducive to improving the noise reduction effect of the inflation mechanism.

[0033] In addition, the sleeve portion is sleeved on the driving element. When the driving element collides with the first shell due to excessive vibration of itself or external force, the sleeve portion can also perform shock absorption and buffering, thereby effectively protecting the driving element and preventing the driving element from collision damage or damage that causes it to be unable to operate.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] In this application, terms such as "upper," "front," "top," "inner," and "outer" indicate positions or locations based on those shown in the accompanying drawings. These terms are intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to specific positions, or to their construction or operation in a specific position.

[0046] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0047] Furthermore, the terms "installed," "disposed," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0048] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0049] An air pump refers to a mechanism that requires manual or electric drive to drive the reciprocating motion of the piston to expel gas from a closed space or to inflate a closed space. During the operation of the air pump, the piston is prone to vibration during the compression of the gas, which can easily cause the air pump to collide with the installation cavity, resulting in relatively loud working noise and even the risk of damage to the air pump or the installation cavity. In the related art, elastic material is usually placed between the air pump and the installation cavity to cushion the vibration of the air pump. However, although this method can achieve a certain shock-absorbing and noise-reducing effect, it is still not ideal. In particular, when the vibration frequency and amplitude of the air pump are large or the installation cavity is light, the installation cavity will still produce a large vibration and noise, and the shock-absorbing effect is not prominent enough.

[0050] To solve the above problem, the inventor tried to install an outer ring of the air pump on the periphery of the air pump, and suspended the air pump in the installation cavity through a cantilever. In this way, the elastic material and cantilever installed on the periphery of the air pump can absorb the vibration generated by the air pump. Moreover, by suspending the air pump in the installation cavity, it is possible to prevent the air pump from colliding with the installation cavity even when the air pump vibration is relatively large. Although this method can further improve the shock absorption and noise reduction effect of the air pump, due to the fixed connection between the cantilever and the installation cavity, when the vibration frequency and amplitude of the air pump are large, some vibration is still transmitted to the installation cavity through the cantilever, causing vibration and noise in the installation cavity.

[0051] In view of this, an embodiment of the present application provides an inflation mechanism and a massage device, wherein the inflation mechanism is sleeved on the driving element through a sleeve portion, and the driving element is suspended in a first installation space within the first shell through a support portion and a cantilever portion. At the same time, a second shock-absorbing component is provided at the connection between the support portion and the cantilever portion, so that the inflation mechanism can achieve multi-level shock absorption of the driving element through the sleeve portion, the cantilever portion and the second shock-absorbing component, and can avoid the driving element from being damaged by collision or being unable to operate due to damage, thereby helping to reduce the working noise of the driving element.

[0052] The technical solution of the present application is further described below through specific embodiments and drawings.

[0053] See also Figures 1 to 3 , Figure 1 is a structural diagram of the inflation mechanism provided in an embodiment of the present application; Figure 2 is a side view of the inflation mechanism provided in an embodiment of the present application; Figure 3 : is a schematic diagram of the exploded structure of the inflation mechanism provided by an embodiment of the present application. In the first aspect, the embodiment of the present application provides an inflation mechanism 100, which includes a first shell 1, a driving element 2, a first shock-absorbing component 3 and a second shock-absorbing component 4. The first shell 1 has a first installation space 11, and the first shell 1 is provided with a support portion 12, which is located in the first installation space 11. The driving element 2 is arranged in the first installation space 11. The first shock-absorbing component 3 includes a sleeve portion 31 and a cantilever portion 32. The sleeve portion 31 is configured to be sleeved on the driving element 2, and the cantilever portion 32 is provided on the sleeve portion 31. The cantilever portion 32 is configured to be connected to the support portion 12 so that the driving element 2 is suspended in the first installation space 11. The second shock-absorbing component 4 is connected to the cantilever portion 32 and the support portion 12.

[0054] In the embodiment of the present application, the sleeve portion 31 is sleeved onto the outside of the driving element 2, and the support portion 12 and the cantilever portion 32 allow the driving element 2 to be suspended in the first installation space 11 of the first housing 1. A second shock-absorbing component 4 is provided at the connection between the support portion 12 and the cantilever portion 32. Thus, on the one hand, during the operation of the driving element 2, the sleeve portion 31 and the cantilever portion 32 can first partially absorb the vibration of the driving element 2. Then, when the cantilever portion 32 transmits part of the vibration of the driving element 2 to the first housing 1, the second shock-absorbing component 4 performs secondary shock absorption, thereby reducing the operating noise of the driving element 2. On the other hand, by sleeved onto the driving element 2, the sleeve portion 31 can be provided to reduce and cushion the driving element 2 when the driving element 2 collides with the first housing 1 due to excessive vibration or external force, thereby effectively protecting the driving element 2 and preventing the driving element 2 from being damaged or unable to operate due to collision.

[0055] Optionally, the material of the first shell 1 includes metal, plastic, organic glass, etc., which is not limited in this embodiment. For example, the material of the first shell 1 is metal. Since metal has high mechanical strength and durability, the first shell 1 can withstand impact, pressure and wear, which is beneficial to protecting the driving element 2 in the first shell 1. For another example, the material of the first shell 1 is plastic. Since plastic has strong corrosion resistance, it can prevent the first shell 1 and the driving element 2 in the first shell 1 from being damaged by corrosion; at the same time, since the weight of plastic is relatively light, the first shell 1 is lightweight, which is beneficial to reducing the mass of the inflation mechanism 100. For another example, the material of the first shell 1 is organic glass. Since organic glass has strong impact resistance and is light in weight, the first shell 1 is lightweight and can effectively resist impact and is not easily broken.

[0056] Optionally, the driving element 2 includes a piston air pump, a diaphragm air pump, a gear air pump, etc., which is not limited in this embodiment.

[0057] Optionally, the material of the first shock-absorbing component 3 includes rubber, silicone, polyurethane, foam, etc., which is not limited in this embodiment. For example, if the first shock-absorbing component 3 is made of rubber, due to its excellent wear resistance, elasticity, shock absorption performance, and recovery ability, the first shock-absorbing component 3 has a long service life, thereby facilitating the increase in the service life of the inflation mechanism 100; at the same time, it can effectively absorb the vibration of the driving element 2, thereby facilitating the reduction of the operating noise of the driving element 2. Alternatively, if the first shock-absorbing component 3 is made of silicone, due to its excellent high temperature resistance, aging resistance, elasticity, and flexibility, on the one hand, the first shock-absorbing component 3 can effectively absorb the vibration of the driving element 2, thereby facilitating the reduction of the operating noise of the driving element 2; on the other hand, it can adapt to different temperature ranges, thereby enabling the inflation mechanism 100 to adapt to different temperature environments. In addition, the first shock-absorbing component 3 has a long service life, thereby facilitating the increase in the service life of the inflation mechanism 100. Alternatively, the first shock-absorbing component 3 may be made of polyurethane. Since polyurethane can have adjustable elasticity and hardness through different formulations, the first shock-absorbing component 3 can have a good shock-absorbing effect while also having a certain hardness, thereby increasing the tensile strength of the first shock-absorbing component 3, thereby facilitating a longer service life of the first shock-absorbing component 3 and, consequently, a longer service life of the inflation mechanism 100. Alternatively, the first shock-absorbing component 3 may be made of foam. Since foam has excellent sound insulation, cushioning, and elastic properties, the first shock-absorbing component 3 can effectively absorb vibrations of the driving element 2 and absorb sound from the driving element 2, thereby facilitating improved shock and noise reduction effects of the inflation mechanism 100.

[0058] It is understandable that the sleeve portion 31 includes a rubber sleeve, a silicone sleeve, a polyurethane sleeve, a foam cavity, etc., which is not limited in this embodiment.

[0059] Optionally, the second shock absorbing component 4 includes a spring, a spring, an elastic gasket, etc., which is not limited in this embodiment. Figure 3As shown, the second shock-absorbing component 4 is a spring. Due to its high elasticity, restoring force, and durability, the second shock-absorbing component 4 can quickly return to its original shape after being subjected to external force, effectively absorbing the vibration of the driving element 2, thereby improving the vibration and noise reduction effects of the inflation mechanism 100. Furthermore, the second shock-absorbing component 4 has excellent fatigue resistance, which helps to increase the service life of the second shock-absorbing component 4, thereby improving the service life of the inflation mechanism 100. Alternatively, the second shock-absorbing component 4 can be a spring. Due to its high elasticity, high strength, and durability, the second shock-absorbing component 4 can effectively absorb the vibration of the driving element 2 while being able to withstand high pressure and stress, thereby improving the durability of the second shock-absorbing component 4. Alternatively, the second shock-absorbing component 4 can be an elastic gasket. Due to its shock-absorbing, sound-insulating, flexible, durable, and weather-resistant properties, the second shock-absorbing component 4 can effectively absorb the vibration of the driving element 2 while reducing noise transmission. Furthermore, the second shock-absorbing component 4 can adapt to different temperature ranges, thereby enabling the inflation mechanism 100 to be used in different temperature environments.

[0060] It is understood that when the second shock-absorbing component 4 includes a spring or a spring, the material of the second shock-absorbing component 4 includes carbon steel, stainless steel, alloy steel, high-temperature alloy, etc., and this embodiment does not limit this. When the second shock-absorbing component 4 includes an elastic gasket, the material of the second shock-absorbing component 4 includes rubber, silicone, foam, etc., and this embodiment does not limit this.

[0061] Since the vibration direction of the driving element 2 is disordered, in order to better reduce the vibration and noise of the driving element 2, it is necessary to absorb the vibrations generated by the driving element 2 in different directions. Based on this, the present application also designs a solution for absorbing the vibrations generated by the driving element 2 in different directions, as shown below:

[0062] As an optional implementation, Figure 3 As shown, the cantilever portion 32 extends along a first direction X, and the second shock-absorbing component 4 is located between the cantilever portion 32 and the support portion 12 along a second direction Y, wherein the second direction Y intersects the first direction X. Since the cantilever portion 32 and the second shock-absorbing component 4 are arranged along the first direction X and the second direction Y, respectively, the cantilever portion 32 and the second shock-absorbing component 4 can better absorb vibrations generated in different directions by the operation of the driving element 2, further improving the vibration and noise reduction effects of the inflation mechanism 100.

[0063] In order to connect the cantilever portion 32 and the support portion 12 tightly, in some optional embodiments, a protrusion K and a connection hole H are respectively provided on the cantilever portion 32 and the support portion 12, and the connection between the cantilever portion 32 and the support portion 12 is tightened by the protrusion K and the connection hole H. Figure 3As shown, the support portion 12 is provided with a protrusion K, the cantilever portion 32 is provided with a connection hole H, the protrusion K is inserted into the connection hole H, and the second shock-absorbing component 4 is at least partially located in the connection hole H. For another example, the cantilever portion 32 is provided with a protrusion K, the support portion 12 is provided with a connection hole H, the protrusion K is inserted into the connection hole H, and the second shock-absorbing component 4 is at least partially located in the connection hole H. The cooperation between the protrusion K and the connection hole H of the support portion 12 and the cantilever portion 32 achieves the fixation of the first shock-absorbing component 3 and the driving element 2, making the shock-absorbing structure of the inflation mechanism 100 more stable; at the same time, the protrusion K fixes the second shock-absorbing component 4 and guides the compression and extension activities of the second shock-absorbing component 4.

[0064] It is understood that the second shock-absorbing component 4 is at least partially located in the connecting hole H. Alternatively, part of the second shock-absorbing component 4 is located in the connecting hole H, while another part of the second shock-absorbing component 4 is sleeved on the protrusion K. Alternatively, the second shock-absorbing component 4 is entirely located in the connecting hole H, the protrusion K is inserted into the connecting hole H, and the top of the protrusion K abuts against the second shock-absorbing component 4. This embodiment is not limited to this.

[0065] It can be understood that in addition to the above-mentioned embodiment in which the second shock-absorbing component 4 is at least partially located in the connecting hole H, the second shock-absorbing component 4 can also be sleeved on the protrusion K, the protrusion K is inserted into the connecting hole H, and the second shock-absorbing component 4 abuts against the top of the connecting hole H.

[0066] Please combine Figure 4 and Figure 5 , Figure 4 yes Figure 2 Cross-sectional view at AA in the middle; Figure 5 yes Figure 2 Cross-sectional view at center BB. In an optional embodiment, the first shell 1 includes a first sub-shell 13 and a second sub-shell 14, the first sub-shell 13 is connected to the second sub-shell 14, the first sub-shell 13 is provided with a first sub-support portion 121, the second sub-shell 14 is provided with a second sub-support portion 122, the cantilever portion 32 is connected between the first sub-support portion 121 and the second sub-support portion 122, one end of the second shock-absorbing component 4 is connected to the cantilever portion 32, and the other end of the second shock-absorbing component 4 is connected to the first sub-support portion 121.

[0069] In this way, the driving element 2 is suspended in the air by connecting the cantilever portion 32 with the first sub-support portion 121 and the second sub-support portion 122. The first sub-support portion 121 and the second sub-support portion 122 are engaged by connecting the first sub-shell 13 and the second sub-shell 14, thereby firmly securing the cantilever portion 32 and improving the reliability of the suspension of the driving element 2. At the same time, the second shock-absorbing component 4 is connected to the first sub-support portion 121 and the second sub-support portion 122, and the first sub-support portion 121 and the second sub-support portion 122 clamp the second shock-absorbing component 4, thereby securing the second shock-absorbing component 4. In addition, by providing the second shock-absorbing components 4 on both sides of the cantilever portion 32 along the second direction Y, the vibration generated by the driving element 2 can be better absorbed, which is beneficial for improving the secondary shock-absorbing effect of the inflation mechanism 100.

[0070] As an optional implementation, Figures 3 to 5 As shown, the first housing 1 is provided with multiple support portions 12 and multiple cantilever portions 32, each of which is connected to a corresponding support portion 12. At least one cantilever portion 32 is connected to a support portion 12 via a second shock-absorbing component 4. The corresponding connection between the multiple support portions 12 and the multiple cantilever portions 32 strengthens the connection between the first shock-absorbing component 3 and the first housing 1, thereby further stably securing the driving element 2. Simultaneously, the multiple cantilever portions 32 cooperate to withstand greater vibration forces from the driving element 2, further enhancing the shock and noise reduction effects of the inflatable mechanism 100. Furthermore, the connection between at least one cantilever portion 32 and the support portion 12 via a second shock-absorbing component 4 reduces the number of components of the inflatable mechanism 100 while maintaining its secondary shock-absorbing effect, simplifying assembly and reducing production costs.

[0071] Alternatively, as Figures 3 to 5 As shown, the first housing 1 is provided with multiple support portions 12, multiple cantilever portions 32, and multiple second shock-absorbing components 4. Each cantilever portion 32 is connected to a corresponding support portion 12, and each cantilever portion 32 and each support portion 12 are connected to a second shock-absorbing component 4. The multiple second shock-absorbing components 4 can better absorb the vibration generated by the driving element 2, thereby improving the secondary shock-absorbing effect of the inflation mechanism 100.

[0072] It is understood that the first shell 1 is provided with a plurality of support portions 12, and the support portions 12 may be two or more, for example, the support portions 12 may be 2, 4, 6, 8, etc., and this embodiment does not limit this. Similarly, the cantilever portions 32 are multiple, and the cantilever portions 32 may be two or more, for example, the cantilever portions 32 may be 2, 4, 6, 8, etc., and this embodiment does not limit this. Similarly, the second shock-absorbing components 4 are multiple, and the second shock-absorbing components 4 may be two or more, for example, the second shock-absorbing components 4 may be 2, 4, 6, 8, etc., and this embodiment does not limit this.

[0073] For example, Figures 3 to 5 As shown, when there are four support portions 12, there are also four cantilever portions 32 and four second shock-absorbing components 4. The four support portions 12 are dispersed around the driving element 2, and each cantilever portion 32 is connected to a corresponding support portion 12. Each cantilever portion 32 and each support portion 12 are connected to a second shock-absorbing component 4. By distributing the four support portions 12 around the driving element 2, the cantilever portions 32 can better fix the driving element 2, thereby making the connection of the driving element 2 more stable and reliable.

[0074] In order to further improve the shock absorption and noise reduction effect of the inflation mechanism 100, the cantilever portion 32 may be designed to further improve the shock absorption effect, which will be described in detail below.

[0075] As an optional embodiment, the cantilever portion 32 includes an extension portion 321 and a connecting portion 322. The extension portion 321 is arranged on the sleeve portion 31, and the extension portion 321 is hollowed out. The connecting portion 322 is connected to the side of the extension portion 321 away from the sleeve portion 31. The connecting portion 322 is provided with a protrusion K, and the extension portion 321 is provided with a connecting hole H.

[0076] As another optional implementation, Figures 3 to 5 As shown, the cantilever portion 32 includes an extension portion 321 and a connecting portion 322. The extension portion 321 is arranged on the sleeve portion 31, and the extension portion 321 is hollowed out. The connecting portion 322 is connected to the side of the extension portion 321 away from the sleeve portion 31. The support portion 12 is provided with a protrusion K, and the connecting portion 322 is provided with a connecting hole H.

[0077] In the above two embodiments, the hollow design of the extension portion 321 can reduce the thickness of the extension portion 321, making the extension portion 321 more easily deformable, further enhancing the shock absorption effect of the cantilever portion 32, thereby facilitating improving the shock absorption and noise reduction effect of the inflation mechanism 100.

[0078] Optionally, the extension portion 321 includes a rubber frame, a silicone frame, a polyurethane frame, a foam frame, etc., which is not limited in this embodiment.

[0079] Optionally, the connecting portion 322 includes a rubber plate, a silicone plate, a polyurethane plate, a foam plate, etc., which is not limited in this embodiment.

[0080] It is understandable that the hollowing out of the extension portion 321 may reduce the strength of the extension portion 321. Therefore, the reinforcement portion 323 may be provided to reduce the effect of the hollowing out on the strength of the extension portion 321. Specifically, Figures 3 to 5 As shown, the cantilever portion 32 also includes a reinforcement portion 323, which is located in the hollowed-out portion of the extension portion 321 and is connected to the connection portion 322 and the sleeve portion 31. The reinforcement portion 323 connects the sleeve portion 31 and the connection portion 322, thereby cooperating with the extension portion 321 to achieve a multi-point connection between the sleeve portion 31 and the connection portion 322. This ensures a more stable connection, better structural stability of the cantilever portion 32, and a more secure connection. Furthermore, the reinforcement portion 323 provides the cantilever portion 32 with greater tensile strength, thereby preventing the extension portion 321 from breaking due to excessive force.

[0081] Optionally, the first shock-absorbing component 3 may comprise the sleeve portion 31, the extension portion 321, the connection portion 322, and the reinforcement portion 323, which are then assembled separately. Alternatively, the sleeve portion 31, the extension portion 321, the connection portion 322, and the reinforcement portion 323 may be integrally formed. By integrally forming the sleeve portion 31, the extension portion 321, the connection portion 322, and the reinforcement portion 323, the overall stability of the first shock-absorbing component 3 is enhanced. Furthermore, the assembly steps of the first shock-absorbing component 3 are simplified, reducing the complexity of assembling the inflation mechanism 100 and making installation more convenient and quick.

[0082] The above-mentioned shock absorption design can reduce the mechanical vibration noise of the inflation mechanism 100, but the absorption of the airflow noise generated by the compressed gas of the inflation mechanism 100 is relatively limited. Therefore, the present application also designs a solution for absorbing the airflow noise of the inflation mechanism 100, as described below:

[0083] As an optional implementation, Figure 4 and Figure 5As shown, the inflator 100 further includes a sound-absorbing assembly 5, which includes a second shell 51 and sound-absorbing cotton 52. The second shell 51 has a second installation space 511, the first shell 1 is disposed in the second installation space 511, and the sound-absorbing cotton 52 is disposed between the first shell 1 and the second shell 51. By disposing the sound-absorbing cotton 52 between the first shell 1 and the second shell 51, the sound-absorbing cotton 52 can absorb the operating noise (including vibration noise and airflow noise) of the driving element 2. In addition, by providing a single set of sound-absorbing cotton 52, the production cost of the inflator 100 can be reduced while maintaining the absorption of the operating noise of the inflator 100.

[0084] Optionally, the sound-absorbing cotton 52 is disposed between the first shell 1 and the second shell 51, and there are multiple implementations. In one exemplary embodiment, the sound-absorbing cotton 52 is connected to the outer wall of the first shell 1. In another exemplary embodiment, the sound-absorbing cotton 52 is connected to the inner wall of the second shell 51. In another exemplary embodiment, as shown in FIG. Figure 4 and Figure 5 As shown, the sound-absorbing cotton 52 is connected to the outer wall of the first shell 1 and the inner wall of the second shell 51, that is, the sound-absorbing cotton 52 completely fills the space formed by the first and second shells. When the sound-absorbing cotton 52 is connected to both the first and second shells 1 and 51, it can absorb the operating noise of the driving element 2. At the same time, the sound-absorbing cotton 52 can achieve the installation and fixation of the first shell 1 without the need for additional components to fix the first shell 1 in the second installation space 511, making the structure of the inflation mechanism 100 more compact. In addition, the sound-absorbing cotton 52 can play a role in damping the vibration of the first shell 1, further improving the vibration and noise reduction effect of the inflation mechanism 100.

[0085] Please combine Figure 6 As shown, Figure 6 Schematic diagram of the structure of the inflatable mechanism provided by the embodiment of the present application with multiple groups of sound absorbing components. Optionally, in an environment where there are strict requirements on the noise of the inflatable mechanism 100, when the vibration reduction and noise reduction effect of a single layer of sound absorbing cotton 52 does not meet the requirements, the vibration reduction and noise reduction effect of the inflatable mechanism 100 can be improved by providing multiple layers of sound absorbing cotton 52. Specifically, Figure 6 As shown, there are multiple groups of sound absorbing components 5, which are sequentially wrapped around the outer periphery of the first shell 1. By providing multiple groups of sound absorbing components 5, the operating noise of the inflation mechanism 100 can be eliminated to the greatest extent, allowing the inflation mechanism 100 to meet the requirements of higher noise control environments.

[0086] It is understandable that the above-mentioned sound absorbing components 5 are multiple groups, which can be 2 groups or more than 2 groups, such as 2 groups, 3 groups, 4 groups, 5 groups, etc., and this embodiment does not limit this.

[0087] In some optional embodiments, the inflation mechanism 100 further includes a gas tank 6. Since the gas will also generate airflow noise during the process of being transferred to the gas tank 6, the present application also designs a solution for absorbing the noise of the gas tank 6. Specifically, Figures 4 to 6 As shown, the inflation mechanism 100 further includes a gas tank 6, which is disposed in the first installation space 11 and connected to the gas outlet of the driving element 2. The connection between the gas tank 6 and the gas outlet of the driving element 2 compresses and stores the gas ejected by the driving element 2, mitigating pressure fluctuations in the output gas. Furthermore, by arranging the gas tank 6 in the first installation space 11, the sound-absorbing cotton 52 absorbs the airflow noise generated when the gas is transferred to the gas tank 6.

[0088] In some optional embodiments, the size of the inflation mechanism 100 can be adapted to various requirements to meet different usage scenarios by designing the positional relationship between the gas tank 6 and the driving element 2. Figures 4 to 6 As shown, the gas tank 6 and the driving element 2 are arranged sequentially along the axis Z of the driving element. By arranging the gas tank 6 and the driving element 2 sequentially along the axis Z of the driving element, the length of the gas transmission pipeline can be reduced, making the arrangement of the gas tank 6 and the driving element 2 more concise, thereby facilitating the assembly of the inflation mechanism 100. For another example, the axis of the gas tank 6 is arranged parallel to the axis of the driving element 2. By arranging the axis of the gas tank 6 parallel to the axis of the driving element 2, the size of the inflation mechanism 100 can be adapted to various needs to meet different usage scenarios.

[0089] Optionally, a plurality of connecting struts 53 are provided on the outer wall of the second housing 51. The connecting struts 53 are symmetrically distributed on the outer wall of the second housing 51. The connecting struts 53 are provided with through holes 531 for mounting the inflation mechanism 100. The inflation mechanism 100 can be fixedly mounted on the device by connecting the struts 53 and the through holes 531.

[0090] See also Figure 7 , Figure 7 is a schematic diagram of the structure of a massage device provided in an embodiment of the present application. In a second aspect, an embodiment of the present application further provides a massage device 200, which includes the inflation mechanism 100 described in the first aspect. This massage device 200 includes, but is not limited to, massage chairs, massage machines, massage sofas, massage cushions, and the like. The massage device 200, including the inflation mechanism 100, also achieves vibration and noise reduction.
