Description

Technical Field

[0001] This utility model relates to ventilation therapy equipment, specifically to a vibration damping mounting assembly for a compressor. Furthermore, this utility model also relates to an oxygen concentrator including the vibration damping mounting assembly. Background Technology

[0002] With the improvement of living standards and the advancement of medical technology, people are paying more and more attention to health. This is especially true for those suffering from chronic respiratory diseases, such as chronic obstructive pulmonary disease (COPD) and asthma, for whom a continuous supply of oxygen is crucial. Portable oxygen concentrators, as a novel medical device, provide convenience for oxygen therapy in daily life. Portable oxygen concentrators typically employ the pressure swing adsorption (PSA) principle, using ambient air as raw material. Under normal temperature and low pressure conditions, they utilize the property that molecular sieves increase their adsorption capacity for nitrogen (adsorbate) in the air when pressurized and decrease it when depressurized, forming a rapid cycle of pressurized adsorption and depressurized desorption, thus separating oxygen and nitrogen from the air.

[0003] As one of the core components of a portable oxygen concentrator, the compressor is used to pressurize ambient air and supply it to the molecular sieve adsorption tower, providing compressed air feedstock for the entire oxygen production process. During operation, the compressor draws in air through the inlet pipe, compresses it via a piston driven by a motor, and then discharges the compressed air through the outlet pipe.

[0004] For patients who need to use portable oxygen concentrators for extended periods or in quiet environments, noise level is a critical technical indicator. Noise can not only affect sleep quality and comfort but also place an additional burden on patients with cardiovascular diseases. The operating noise generated by compressor vibration is the primary source of noise in oxygen concentrators. Therefore, it is necessary to install the compressor appropriately within the oxygen concentrator casing to minimize the transmission of compressor vibration kinetic energy to the casing or related connecting bases, thereby reducing the noise level.

[0005] Existing oxygen concentrators typically use vibration-damping pads to reduce compressor vibration and noise. These pads are made of soft rubber material, which absorbs and isolates vibrations to reduce the transmission of vibration and noise. However, due to issues such as the design of the vibration-damping structure's support or the unreasonable hardness of the material, the actual vibration reduction and noise reduction effect is often unsatisfactory. Utility Model Content

[0006] The purpose of this invention is to overcome the problem of poor vibration damping and noise reduction in the compressor of oxygen concentrators in the prior art, and to provide a vibration damping mounting component for the compressor. This vibration damping mounting component can effectively absorb the vibration energy generated during the operation of the compressor, reduce the outward transmission of vibration and noise, thereby improving the user experience of the oxygen concentrator.

[0007] To achieve the above objectives, this utility model provides a vibration damping mounting assembly for an oxygen concentrator, used to supply compressed air to the oxygen generation unit of the oxygen concentrator. The vibration damping mounting assembly includes a compressor body, a vibration damping seat located at the bottom of the compressor body, and an elastic suspension structure connected to the compressor body. When the vibration damping mounting assembly is assembled to the oxygen concentrator, the elastic suspension structure is configured to elastically apply an upward pulling force to the compressor body.

[0008] Preferably, the compressor outlet of the compressor body is connected to an outlet pipe for supplying compressed air to the oxygen generating unit, and at least one of the elastic suspension structures is integrated into the outlet pipe to apply an upward pulling force to the compressor body at the compressor outlet.

[0009] Preferably, the elastic suspension structure extends at least partially in parallel with the air outlet duct and is connected to different locations along the extension direction of the air outlet duct.

[0010] Preferably, the compressor body includes a first compression unit and a second compression unit arranged and connected together along a first direction. The outlet pipeline includes an outlet connecting pipe section and an outlet connecting pipe section. The outlet connecting pipe section extends along the first direction and is connected at both ends to the compressor outlets of the first compression unit and the second compression unit, respectively. The outlet connecting pipe section is connected to the outlet connecting pipe section and extends at least partially along a second direction perpendicular to the first direction. The elastic suspension structure is connected to the portion of the outlet connecting pipe section extending along the second direction and forms a suspension portion at the portion extending out of the outlet connecting pipe section.

[0011] Preferably, the suspension portion is located at the free end of the extension of the air outlet connecting pipe section of the elastic suspension structure, and has a connection structure for connecting to the compressor mounting chamber of the oxygen generator.

[0012] Preferably, the portion of the elastic suspension structure extending from the air outlet connecting pipe section has a groove that is adjacent to the air outlet connecting pipe section and opens downward. When the shock-absorbing mounting assembly is assembled to the oxygen generator, the portion of the elastic suspension structure extending from the air outlet connecting pipe section is bent upward at the location of the groove relative to the portion of the elastic suspension structure connected to the air outlet connecting pipe section.

[0013] Preferably, the shock absorber has a rim portion, a hub portion protruding upward relative to the rim portion, and a deformable portion connected between the hub portion and the rim portion, wherein a through hole is formed at the center of the hub portion for fasteners to pass through and connect to the compressor body.

[0014] Preferably, an annular groove is formed on the outer periphery of the rim portion.

[0015] Preferably, the bottom of the compressor body is provided with a plurality of shock-absorbing seats, at least some of which are formed as hollow corrugated tubes and connected to the compressor inlet of the compressor body.

[0016] Preferably, the compressor inlet of the compressor body is connected to an intake pipe. When the shock-absorbing mounting assembly is assembled to the oxygen generator, the intake pipe is configured to apply an angled force to the compressor body relative to the vertical and horizontal directions.

[0017] Preferably, the compressor body includes a first compression unit and a second compression unit arranged and connected together along a first direction. The intake pipe includes an intake connecting pipe section and an intake connecting pipe section. The intake connecting pipe section is disposed on the outside of the compressor body and extends along the first direction. The two ends of the intake connecting pipe section are respectively connected to the compressor intake ports of the first compression unit and the second compression unit. The intake connecting pipe section is connected to the intake connecting pipe section and extends obliquely at least partially along a direction that is at an angle relative to the vertical and horizontal directions.

[0018] A second aspect of this invention provides an oxygen generator including the aforementioned shock-absorbing mounting components.

[0019] Through the above technical solution, the shock-absorbing mounting assembly of this utility model uses an elastic suspension structure to suspend the compressor body to the relevant connection foundation. In this way, the vibration energy generated by the compressor body can be consumed by the elastic tension of the shock-absorbing seat and the elastic suspension structure during the operation of the compressor, thereby reducing the outward transmission of vibration and noise, thus improving the user experience of the oxygen concentrator.

Detailed Implementation

[0033] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0034] In this utility model, unless otherwise stated, directional terms such as "up," "down," "left," "right," "front," and "back" generally refer to reference to... Figure 1 The directions shown are up, down, left, right, front, and back. "Inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0035] Reference Figure 1 As shown, this utility model provides a vibration damping mounting assembly for a compressor, used in an oxygen generator to supply compressed air to the oxygen generation unit (such as a molecular sieve adsorption tower) of the oxygen generator. Combined with... Figures 2 to 4 The vibration damping mounting assembly includes a compressor body 1, a vibration damping seat 2 located at the bottom of the compressor body 1, and an elastic suspension structure 3 connected to the compressor body 1. The compressor body 1 is used to pressurize the intake air and supply it to the oxygen generation unit of the oxygen concentrator as needed, providing compressed air feedstock for the entire oxygen generation process. As described below, the compressor body 1 may be connected to an intake pipe 5 and an outlet pipe 4. The intake end of the intake pipe 5 can receive ambient air filtered by the intake assembly to remove any impurities that may be present in the air, ensuring the compressor's service life. The outlet end of the outlet pipe 4 can be connected to a control valve, which controls the timely supply of compressed air to the oxygen generation unit.

[0036] The shock absorber 2, serving as the bottom support element of the compressor body 1, is typically made of a soft material to elastically support the compressor body 1 and secure its bottom mounting position within the oxygen concentrator. The elastic suspension structure 3 is configured to elastically apply an upward pulling force to the compressor body 1 when the shock absorber mounting assembly is assembled into the oxygen concentrator. For example, the elastic suspension structure 3 can be made of an elastic material and connect to the compressor body 1 on one side and suspend from the main frame 100 of the oxygen concentrator and other related connecting foundations on the other. Therefore, during the operation of the compressor, its internal motor drives the crank connecting rod piston to reciprocate to obtain compressed air, while generating high-speed vibration mainly in the vertical direction. The vibration damping mounting assembly of this utility model can dissipate the vibration energy generated by the compressor body 1 through the elastic pulling action of the vibration damping seat 2 and the elastic suspension structure 3. The elastic suspension structure 3 elastically applies an upward pulling force to the compressor body 1, while the vibration damping seat 2 elastically acts on the bottom of the compressor body 1 and can be set to slightly pull down the compressor body 1. Thus, the compressor body 1 is suspended in between, thereby effectively fixing the compressor while reducing the outward transmission of vibration and noise, thereby improving the user experience of the oxygen concentrator.

[0037] As mentioned above, the compressor body 1 can be connected to an inlet pipe 5 and an outlet pipe 4. The inlet pipe 5 is connected to the compressor inlet 11 of the compressor body 1 for introducing filtered ambient air; the outlet pipe 4 is connected to the compressor outlet 12 of the compressor body 1 for delivering compressed air to the oxygen generation unit. In a preferred embodiment, as... Figure 6 and Figure 7 As shown, the elastic suspension structure 3 can be integrated into the outlet pipe 4, so that an upward pulling force can be applied to the compressor body 1 at the compressor outlet 12 through the outlet pipe 4. Typically, according to the compression principle and the layout requirements of the portable oxygen concentrator, the compressor outlet 12 is located near the top of the compressor body 1. Integrating the elastic suspension structure 3 and the outlet pipe 4 into one unit not only helps reduce the number of components in the oxygen concentrator, but also avoids the need for a separate additional connection structure on the compressor body 1 to connect the elastic suspension structure 3. The elastic suspension structure 3 and the outlet pipe 4 can be made of a single piece of soft rubber material, which not only reduces the airflow noise generated during compressed gas delivery, but also significantly reduces the transmission of vibration energy generated by the compressor body 1 by forming a suspension connection between the compressor body 1 and the relevant connecting base (such as the main frame 100 made of rigid material), thus achieving good suspension support and noise reduction effects. This integrated design helps reduce the number of parts in the oxygen concentrator, saves space, makes the product more compact, improves the integration and portability of the product, and also reduces the overall weight, which is conducive to the miniaturization of the oxygen concentrator.

[0038] In other embodiments, the elastic suspension structure 3 can also be directly connected to the compressor body 1, thereby directly applying an upward pulling force to the compressor body 1. Furthermore, the vibration damping mounting assembly of the illustrated preferred embodiment only has a single elastic suspension structure 3 integrally formed with the outlet pipe 4, which extends forward from the outlet pipe 4. However, in other embodiments of the vibration damping mounting assembly, another elastic suspension structure can be further provided, integrally formed with the outlet pipe 4 and extending rearward from the outlet pipe 4 or directly connected to the compressor body 1. The forward and / or rearward extending portion of the elastic suspension structure 3 can abut against the inner wall of the compressor mounting chamber to elastically limit the position of the compressor body 1 in the front-rear direction, preventing it from tilting forward or backward and reducing the outward transmission of vibration and noise. Although it is advantageous to provide multiple symmetrically arranged elastic suspension structures for applying tension to the compressor body 1 in a balanced manner, especially since multiple elastic suspension structures can absorb the energy of the compressor body 1’s front and rear vibrations by abutting against the inner wall of the compressor mounting chamber in the front and rear directions, this may not be optimal for the limited space of the portable compressor. Therefore, the preferred embodiment shown in the figure has only a single elastic suspension structure 3.

[0039] Continue to refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, depending on the airflow requirements, the outlet pipe 4 may have a portion extending horizontally in the front-back and / or left-right directions, and a portion extending vertically. The elastic suspension structure 3 extends at least partially parallel to the outlet pipe 4 and is connected to different positions along the extension direction of the outlet pipe 4. That is, at least a portion of the elastic suspension structure 3 and the outlet pipe 4 extend in parallel and can be connected together in these parallel extension portions, or form multiple connections within the length of the parallel extension. Thus, the elastic suspension structure 3 can be securely connected to the outlet pipe 4 to apply sufficient tension to the compressor body 1 through the outlet pipe 4. Furthermore, connecting the elastic suspension structure 3 and the parallel extension portion of the outlet pipe 4 as a single unit can also improve the strength of that portion of the outlet pipe 4.

[0040] Typically, an oxygen generator may include a first oxygen generating unit and a second oxygen generating unit that alternately perform adsorption oxygen generation and desorption nitrogen removal steps. The first and second oxygen generating units can be two sieves in the adsorption tower of the oxygen generator, respectively. To provide sufficient compressed air, the compressor body 1 may include a first compression unit and a second compression unit. These units can be arranged and connected together along a first direction (i.e., the left-right direction shown in the figure). Internally, a motor drives a crank-connecting rod piston to reciprocate, thereby obtaining a continuous supply of compressed air.

[0041] Therefore, the exhaust pipe 4 may include an exhaust connecting pipe section 41 and an exhaust connecting pipe section 42. The exhaust connecting pipe section 41 extends along a first direction (i.e., the left-right direction shown in the figure) and connects to the compressor exhaust ports 12 of the first and second compression units at both ends, respectively. The exhaust connecting pipe section 42 connects to the exhaust connecting pipe section 41 and extends at least partially along a second direction perpendicular to the first direction (i.e., the front-back direction shown in the figure). In this case, the elastic suspension structure 3 can be connected to the portion of the exhaust connecting pipe section 42 extending along the second direction, and a suspension portion 31 is formed at the portion extending from the exhaust connecting pipe section 42. Thus, the elastic suspension structure 3 can not only elastically pull the compressor body 1 upwards, but also restrict the position of the compressor body 1 in the front-back direction to a certain extent.

[0042] When the outlet pipe 4 is connected to the compressor outlet 12 of the first and second compression units via the outlet connecting pipe section 41 as described above, and outputs compressed air to the adsorption tower via the outlet connecting pipe section 42, the outlet pipe 4 is configured as a three-way pipe structure. The elastic suspension structure 3 can be connected to the middle position of the outlet pipe 4 and is integrally formed with the outlet pipe 4. This facilitates applying an upward pulling force to the outlet pipe 4 by suspending the elastic suspension structure 3 upwards, thereby promoting a uniform damping effect in all directions.

[0043] Furthermore, the portion of the flexible suspension structure 3 extending into the outlet connecting pipe section 42 (suspension part 31) can abut against the inner wall of the compressor mounting chamber to elastically limit the position of the compressor body 1 in the longitudinal direction, preventing it from tilting forward or backward. The suspension part 31 can be located at the free end of the flexible suspension structure 3 and can be suspended and connected to the relevant connection base in various suitable ways. For example... Figure 5 As shown, the oxygen concentrator may have an integral main frame 100 forming a compressor mounting chamber, etc., which may have a U-shaped groove opening towards the front, and the suspension part 31 has a snap-fit ​​groove 31a for snapping into the U-shaped groove (see...). Figure 6 This allows for easy assembly and connection. In other embodiments, the connection structure of the elastic suspension structure 3 for connecting to the top wall of the compressor mounting chamber or other related connection bases can also be in the form of hooks, buckles, or other forms. In another embodiment, the outlet connection pipe section 41 is horizontally connected to the compressor outlet port 12, and the horizontal portion of the outlet connection pipe section 41 is connected to one end of the elastic suspension structure 3. The other end of the elastic suspension structure 3 is vertically upward connected to the compressor mounting chamber outside the compressor. Preferably, the elastic suspension structure 3 can be positioned in the middle of the horizontal portion of the outlet connection pipe section 41, which is more conducive to achieving the compressor's vibration damping effect.

[0044] To facilitate molding and processing, and to ensure sufficient elastic deformation space for the elastic suspension structure 3, the portion of the elastic suspension structure 3 extending out of the air outlet connecting pipe section 42 also forms a downward-opening groove 32 adjacent to the air outlet connecting pipe section 42. When the vibration damping mounting assembly is assembled into the oxygen generator, the portion of the elastic suspension structure 3 extending out of the air outlet connecting pipe section 42 bends upward at the location of this groove 32 relative to the portion of the elastic suspension structure 3 connected to the air outlet connecting pipe section 42. Thus, during manufacturing, the elastic suspension structure 3 and the air outlet pipe 4 can be molded as follows: Figure 6 The structure shown has the elastic suspension structure 3 in a natural, unsuspended state, allowing for easy molding. During assembly, the suspension portion 31 of the elastic suspension structure 3 is bent upwards along the groove 32. Figure 7The bending state shown is adapted to allow its snap-fit ​​groove 31a to snap into the U-shaped groove on the main frame 100, which facilitates the application of force to the compressor body 1 and makes it easier for the suspension part 31 to be confined in the snap-fit ​​assembly position and deformation state by the inner wall surface of the compressor mounting chamber.

[0045] Reference Figures 1 to 4 As shown, in a preferred embodiment of this invention, the intake pipe 5 is configured to apply an angled force to the compressor body 1 relative to the vertical and horizontal directions. This configuration helps limit the lateral sway of the compressor body 1 during operation.

[0046] Specifically, as described above, the compressor body 1 may include a first compression unit and a second compression unit arranged and interconnected along a first direction, each having a compressor inlet 11. The intake pipe 5 includes an intake connecting pipe section 51 and an intake connecting pipe section 52. The intake connecting pipe section 51 is located on one side of the compressor body 1 where the compressor inlet 11 is located and extends along the first direction. Both ends of the intake connecting pipe section 51 are connected to the compressor inlets 11 of the first and second compression units, respectively. The intake connecting pipe section 52 is connected to the intake connecting pipe section 51 and extends at least partially at an angle relative to the vertical and horizontal directions. The end of the intake connecting pipe section 52 away from the intake connecting pipe section 51 can be connected to the purified air outlet of the intake assembly. Thus, the intake pipe 5 can restrict the swaying of the compressor body 1 in the left-right direction. Specifically, in this scheme, the two compressor inlets 11 of the first and second compression units are symmetrical to each other, so that the intake connecting pipe section 51 is set in the horizontal direction, and the intake connecting pipe section 52 is set in the middle section of the intake connecting pipe section 51 and extends upward so that the intake connecting pipe section 52 and the intake connecting pipe section 51 form an angle, so as to reduce the left and right sway amplitude when the compressor is running.

[0047] The intake connection pipe section 51 of the intake pipe 5 can be connected to the compressor inlet 11 of the first compression unit and the second compression unit through the intake connector 6, and a sealing ring 7 can be provided at the connection position. During the assembly process, the intake connector 6 can be first sealed and connected to the compressor inlet 11 of the first compression unit and the second compression unit respectively, and then both ends of the intake connection pipe section 51 can be connected to the intake connector 6 to form the compressor intake air passage.

[0048] Figure 8a and Figure 8b , Figure 9a and Figure 9b as well as Figure 10a and Figure 10bThree different shock absorber seats 2 that can be used in the shock-absorbing mounting assembly of this application are shown. As the main support and shock-absorbing component of the compressor body 1, the shock absorber seat 2 can be configured to have a rim portion 21, a hub portion 23 protruding upward relative to the rim portion 21, and a deformation portion 22 connecting the hub portion 23 and the rim portion 21. The center of the hub portion 23 can be formed with a through hole for fasteners to pass through and connect to the compressor body 1. The shock absorber seat 2 can be made mainly of soft material, and its hub portion 23 can be wrapped with a metal sheet so as to be connected to the bottom of the compressor body 1 by fasteners such as screws 9 passing through the through hole in its center; the outer periphery of the rim portion 21 can be formed with an annular groove 21a so as to snap onto the compressor mounting plate 8 fixed to the main frame 100.

[0049] exist Figure 8a and Figure 8b In the shock absorber 2 shown, the deformation portion 22 extends from the portion of the rim portion 21 located above the annular groove 21a and has a concave U-shaped cross-section portion. The lowest point of the U-shaped cross-section portion is higher than the lower edge of the rim portion 21, so that it can provide elastic support to the compressor body 1 through deformation of the U-shaped cross-section portion.

[0050] exist Figure 9a and Figure 9b In the shock absorber 2 shown, the deformation section 22 includes a bellows section extending vertically. The top end of the bellows section is connected to the hub section 23, and the bottom end extends to be flush with the bottom surface of the rim section 21. The rim section 21 has an outer periphery surrounding the bellows section and a connecting portion extending from the bottom end of the outer periphery and connecting to the bottom end of the bellows section. This allows the bellows section to have a relatively long length and form as many bending points as possible, ensuring a good shock absorption effect. By setting the deformation section 22 to include a bellows section, not only can the elastic properties of the material of the deformation section 22 itself be used to buffer vibration, but the elastic expansion and contraction of its bellows section can also enhance the shock absorption effect, thereby achieving a better noise reduction effect.

[0051] exist Figure 10a and Figure 10b In the shock absorber 2 shown, the deformable part 22 is formed as multiple spokes distributed in the circumferential direction, which helps to reduce the weight of the oxygen generator and is conducive to its portability.

[0052] Figure 11 A vibration damping mounting assembly for a compressor according to another preferred embodiment of the present invention is shown, wherein a plurality of vibration damping seats 2 are provided at the bottom of the compressor body 1, and at least some of the vibration damping seats 2 can be formed as hollow corrugated tubes, thereby having a better vibration damping effect compared to the vibration damping seats of the aforementioned form. Thus, this vibration damping mounting assembly can even eliminate the need for the elastic suspension structure 3 that applies an upward pulling force to the compressor body 1.

[0053] Among them, because the shock absorber seat 2 has a hollow channel, Figure 11 The shock-absorbing mounting assembly shown also connects directly to the compressor inlet 11 of the compressor body 1 to serve as an intake pipe, which further enhances the product's compactness and integration.

[0054] This utility model also provides an oxygen generator including the above-mentioned shock-absorbing mounting components.

[0055] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
