Description

Technical Field

[0001] This utility model relates to the field of small household appliances, and in particular to a shock-absorbing and buffering structure and an oxygen generator. Background Technology

[0002] In the field of small household appliances, equipment vibration often leads to noise and wear between components. Prolonged vibration not only significantly reduces the user experience but also shortens the lifespan of the equipment. Therefore, vibration control technology is crucial for small household appliances, especially highly precision equipment like oxygen concentrators. Although current shock absorption and cushioning technologies have made some progress in structural design and energy dissipation, some significant limitations still exist.

[0003] Traditional vibration damping structures often use basic components such as springs or rubber pads. These designs perform poorly in dealing with high-frequency vibrations and shocks, making it difficult to effectively reduce the adverse effects of vibration on equipment and its surrounding components. In addition, traditional vibration damping structures lack multi-component coordinated damping designs, making it difficult to meet the high requirements for vibration control under complex operating conditions.

[0004] Existing vibration damping technologies also have shortcomings in energy dissipation. They mainly rely on the elastic deformation of materials to absorb and dissipate energy, but this method is not effective in dealing with large amplitude and high frequency vibrations and cannot effectively reduce the peak impact effect, thus affecting the stability and service life of the equipment. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a shock-absorbing and buffering structure and an oxygen generator, so as to solve the problems of insignificant shock absorption effect and low vibration energy dissipation efficiency caused by the use of traditional shock-absorbing structures in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides a shock-absorbing and buffering structure that supports the main body generating vibration and reduces its vibration impact, including:

[0007] The buffer component includes an elastic buffer rib, a buffer connecting seat disposed in the middle of one side of the elastic buffer rib, and buffer elastic support columns disposed at both ends of the elastic buffer rib. The elastic buffer rib has a mounting groove in the middle, and the vibration generating body is disposed in the mounting groove.

[0008] The shock-absorbing bracket has a buffer connecting seat and a buffer elastic support mounted on it. The buffer connecting seat and the buffer elastic support support bear the weight of the vibration generating body. When the vibration generating body vibrates, the kinetic energy is transferred to the buffer elastic support and the buffer connecting seat through the elastic buffer rib. The elastic buffer rib swings around the buffer connecting seat as a fulcrum due to the deformation of the buffer elastic support and the buffer connecting seat.

[0009] As a more preferred embodiment, the lower end face of the shock absorber bracket is provided with a positioning groove and a positioning hole that penetrates the positioning groove; the buffer connecting seat is provided with a buffer connecting seat abutting part that penetrates the positioning hole and abuts against the lower part of the elastic buffer rib, and a buffer connecting seat snapping part that snaps into the positioning groove.

[0010] As a more preferred embodiment, the shock absorber bracket is provided with a positioning cover plate, which also has a fastening through hole. The buffer connecting seat has a fixing ear, which has a locking through hole that matches the fastening through hole. A locking element passes through the fastening through hole and the locking through hole to lock and fix the buffer connecting seat to the positioning cover plate. The advantage is that by using a locking element to lock and fix the buffer connecting seat to the positioning cover plate through the fastening through hole and the locking through hole, the connection strength between the buffer connecting seat and the shock absorber bracket is further enhanced, preventing loosening or detachment during vibration and ensuring the long-term stable operation of the shock absorber structure.

[0011] As a more preferred embodiment, the shock-absorbing bracket and the elastic buffer rib are respectively provided with shock-absorbing holes and fixing holes; the two ends of the buffer elastic support are provided with limiting plates made of flexible structure, so that the limiting plates can pass through the shock-absorbing holes and fixing holes by extrusion deformation and form a snap-fit ​​with the shock-absorbing holes and fixing holes.

[0012] As a more preferred embodiment, the buffer elastic support column is provided with a spherical buffer section in the middle. The diameter of the spherical buffer section is larger than that of the damping hole and the fixing hole. The upper and lower ends of the spherical buffer section abut against the edges of the damping hole and the fixing hole, respectively. The spherical buffer section rapidly disperses the impact force generated by vibration in multiple directions and transmits it to the damping bracket through the damping seat. Its advantages are that this multi-directional force dispersion method can more effectively reduce the peak impact value, improve the damping effect, and reduce impact damage to the damping bracket and other components.

[0013] As a more preferred approach, the vibration damping structure includes two or more of the aforementioned buffer components to provide better cushioning for the vibration-generating body. Its advantages lie in the fact that the use of multiple buffer components can provide a more comprehensive and uniform cushioning effect for the vibration-generating body, further reducing the impact of vibration on its surrounding components and improving the overall vibration damping performance and operational stability of the equipment.

[0014] As a more preferred approach, the rigidity of the deformation of the buffer connecting seat is greater than the rigidity of the deformation of the buffer elastic support.

[0015] As a more preferred embodiment, the buffer is provided with a connecting bolt hole for connecting to the vibration generating body.

[0016] To address the aforementioned problems, this utility model also provides an oxygen generator, comprising:

[0017] The aforementioned shock absorption and buffer structure;

[0018] A compressor, which is disposed within the mounting slot.

[0019] As a more preferred approach, the buffer element is arranged at an angle to provide space for piping installation on the oxygen concentrator. The advantage is that by tilting the buffer element at a specific angle, it can better accommodate the piping installation inside the oxygen concentrator, avoid interference, and ensure the normal operation of the equipment.

[0020] As a more preferred embodiment, the oxygen concentrator also includes a molecular sieve barrel, with the shock-absorbing bracket straddling the molecular sieve barrel and a space between it and the molecular sieve barrel for isolating compressor vibration. The advantages of this design are: it effectively isolates the impact of compressor vibration on the molecular sieve barrel, preventing vibration from being transmitted to the molecular sieve barrel, thereby protecting the structure and performance of the molecular sieve barrel, avoiding molecular sieve failure or damage due to vibration, and ensuring the normal oxygen production function of the oxygen concentrator.

[0021] As described above, the shock-absorbing and buffering structure and oxygen generator of this utility model have the following beneficial effects: When in use, the shock-absorbing and buffering structure of this utility model, through the combined design of elastic buffer ribs, buffer connecting seats and buffer elastic support columns, can effectively bear the weight of the main body that generates vibration. When vibration occurs, the swinging of the elastic buffer ribs and the deformation of the buffer elastic support columns dissipate the impact energy, reduce the peak impact effect, thereby reducing the impact of vibration on surrounding components and improving the stability and service life of the equipment. It should be emphasized that the core of this "seesaw" type shock-absorbing structure design, which utilizes the up-and-down swinging of the two ends of the elastic buffer ribs, lies in its ability to convert the impact force into controllable motion through a simple dynamic mechanism. This controllable up-and-down motion is further dissipated little by little through the continuous deformation of the buffer elastic support columns, thereby achieving the effect of shock absorption and protection.

[0022] The oxygen generator of this invention adopts the above-mentioned shock absorption and buffer structure to mitigate the vibration of the compressor, the main vibration source in the equipment. This improves the operational stability and reliability of the oxygen generator, protects other tightly fitted internal components, reduces noise, enhances the user experience, and extends its service life.

[0023] In summary, the shock-absorbing and buffering structure and oxygen concentrator of this utility model, through the combined design of elastic buffer ribs, buffer connecting seats and buffer elastic support columns, utilize the characteristics of a "seesaw" type shock-absorbing structure to effectively dissipate the vibration of the compressor, solving the problems of insignificant shock absorption effect and low vibration energy dissipation efficiency caused by the use of traditional shock-absorbing structures in existing oxygen concentrators.

[0061] like Figures 1 to 5 As shown, this utility model provides a shock-absorbing and buffering structure that supports the main body that generates vibration and reduces its vibration impact, including:

[0062] The buffer component 1 includes an elastic buffer rib 11, a buffer connecting seat 12 disposed in the middle of one side of the elastic buffer rib 11, and buffer elastic support columns 13 disposed at both ends of the elastic buffer rib 11. The elastic buffer rib 11 is provided with a mounting groove 113 in the middle, and the vibration generating body is disposed in the mounting groove 113.

[0063] The shock-absorbing bracket 2, the buffer connecting seat 12 of the buffer component 1 and the buffer elastic support 13 are disposed on the shock-absorbing bracket 2. The buffer connecting seat 12 and the buffer elastic support 13 bear the weight of the vibration generating body. At the same time, when the vibration generating body vibrates, the kinetic energy is transmitted to the buffer elastic support 13 and the buffer connecting seat 12 through the elastic buffer rib 11. Through the deformation of the buffer elastic support 13 and the buffer connecting seat 12, the elastic buffer rib 11 swings with the buffer connecting seat 12 as the fulcrum.

[0064] To better illustrate the shock-absorbing and buffering structure of this utility model, the following specific application will be used as an example: In use, the combined design of the elastic buffer ribs 11, buffer connecting seats 12, and buffer elastic support columns 13 effectively supports the weight of the vibrating component. When vibration occurs, the swinging of the elastic buffer ribs 11 and the deformation of the buffer elastic support columns 13 dissipate the impact energy, reducing the peak impact effect and thus minimizing the impact of vibration on surrounding components, improving equipment stability and service life. It is important to emphasize that this "seesaw"-like shock-absorbing structure design, utilizing the up-and-down swinging of the two ends of the elastic buffer ribs 11, is based on a simple dynamic mechanism that converts the impact force into controllable motion. This controllable up-and-down motion is further dissipated little by little through the continuous deformation of the buffer elastic support columns 13, thereby achieving the effects of shock absorption and protection.

[0065] In some possible embodiments of this utility model, such as Figure 1 , Figure 2 as well as Figure 3As shown, the shock absorber bracket 2 is provided with a positioning cover plate 21. The lower end face of the positioning cover plate 21 is provided with a positioning groove 211 and a positioning hole 212 that passes through the positioning groove 211. The buffer connecting seat 12 is provided with a buffer connecting seat abutment part 122 that passes through the positioning hole 212 and abuts against the lower part of the elastic buffer rib 11, and a buffer connecting seat snap-fit ​​part 121 that snaps into the positioning groove 211. The buffer connecting seat 12 includes a buffer connecting seat snap-fit ​​part 121 and a buffer connecting seat abutment part 122 that is provided at one end on the buffer connecting seat snap-fit ​​part 121. The other end of the buffer connecting seat abutment part 122 passes through the positioning hole 212 from the bottom of the positioning cover plate 21 and abuts against the lower part of the middle of the elastic buffer rib 11. The buffer connecting seat snap-fit ​​part 121 snaps into the positioning groove 211 and fits and is fixed to the positioning cover plate 21. Its beneficial effects are as follows: This design enables the buffer connecting seat 12 to be stably fixed on the shock-absorbing bracket 2. Through the cooperation between the buffer connecting seat snap part 121 and the positioning groove 211, and the connection between the buffer connecting seat abutment part 122 and the positioning hole 212, a firm connection between the buffer component 1 and the shock-absorbing bracket 2 is ensured, thereby improving the reliability and stability of the entire shock-absorbing and buffering structure.

[0066] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 As shown, the positioning cover plate 21 is also provided with a fastening through hole 213, and the buffer connecting seat snap-fit ​​part 121 is provided with a fixing ear 121a. The fixing ear 121a has a locking through hole 121b adapted to the fastening through hole 213. The buffer connecting seat snap-fit ​​part 121 and the positioning cover plate 21 are locked and fixed by a locking member passing through the fastening through hole 213 and the locking through hole 121b. The beneficial effect is that by using the locking member to lock and fix the buffer connecting seat snap-fit ​​part 121 and the positioning cover plate 21 through the fastening through hole 213 and the locking through hole 121b, the connection strength between the buffer connecting seat 12 and the shock absorber bracket 2 is further enhanced, preventing loosening or separation during vibration and ensuring the long-term stable operation of the shock absorber and buffer structure.

[0067] In some possible embodiments of this utility model, such as Figure 4 As shown, the shock-absorbing bracket 2 and the elastic buffer rib 11 are respectively provided with shock-absorbing holes 222a and fixing holes 111a; the two ends of the buffer elastic support column 13 are provided with limiting plates 131 made of flexible structure, so that the limiting plates 131 can pass through the shock-absorbing holes 222a and fixing holes 111a by extrusion deformation, and form a snap-fit ​​with the shock-absorbing holes 222a and fixing holes 111a.

[0068] In some possible embodiments of this utility model, such as Figure 4As shown, the shock-absorbing bracket 2 has two shock-absorbing seats 22, each including a shock-absorbing cavity 221 and a shock-absorbing cover plate 222. The shock-absorbing cover plate 222 has shock-absorbing holes 222a. Limiting plates 131 are provided at both ends of the buffer elastic support column 13. One end of the limiting plate 131 is connected to one end of the elastic buffer rib 11, and the other end is inserted into the shock-absorbing cavity 221 through the shock-absorbing hole 222a. The other end of the limiting plate 131 abuts against the shock-absorbing cover plate 222 from the inside of the shock-absorbing cavity 221. Its beneficial effects are: this structure can effectively limit the range of motion of the buffer elastic support column 13, preventing excessive displacement or detachment during vibration; at the same time, the shock-absorbing cavity 221 and the shock-absorbing cover plate 222 can also provide additional shock absorption, further reducing vibration transmission.

[0069] In some possible embodiments of this utility model, such as Figure 3 As shown, a spherical buffer section 132 is provided in the middle of the buffer elastic support 13. The diameter of the spherical buffer section 132 is larger than that of the damping hole 222a and the fixing hole 111a. The upper and lower ends of the spherical buffer section 132 abut against the edges of the damping hole 222a and the fixing hole 111a, respectively. The spherical buffer section 132 quickly disperses the impact force generated by vibration in multiple directions on the sphere and transmits it to the damping bracket 2 through the damping seat 22. Its beneficial effect is that this multi-directional force dispersion method can more effectively reduce the peak impact, improve the damping effect, and reduce impact damage to the damping bracket 2 and other components.

[0070] In some possible embodiments of this utility model, such as Figure 3 As shown, the elastic buffer rib 11 includes two end connecting portions 111 and a U-shaped connecting portion 112 integrally formed with the two end connecting portions 111. The mounting groove 113 is disposed on the upper side of the U-shaped connecting portion 112. The end connecting portion 111 is provided with a fixing hole 111a. The fixing hole 111a is sleeved on one end of the buffer elastic support 13. The end connecting portion 111 abuts against and is limited by the limiting plate 131. Its beneficial effects are: the design of the U-shaped connecting portion 112 makes the elastic buffer rib 11 have better elasticity and toughness, and can better adapt to the movement of the vibration generating body. At the same time, the mounting groove 113 is disposed on the upper side of the U-shaped connecting portion 112, providing a stable installation position for the vibration generating body and ensuring its stability during operation. Furthermore, in this embodiment, the diameter of the fixing hole 111a is larger than that of the spherical buffer portion 132, and the end connecting portion 111 abuts against the upper part of the spherical buffer portion 132.

[0071] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2As shown, the shock absorption and buffer structure includes two or more buffer components 1 to provide better buffering for the vibration-generating body. Its beneficial effects are: the use of multiple buffer components 1 can provide a more comprehensive and uniform buffering effect for the vibration-generating body, further reducing the impact of vibration on its surrounding components, and improving the overall shock absorption performance and operational stability of the equipment.

[0072] In some possible embodiments of this utility model, the rigidity of the deformation of the buffer connecting seat 12 is greater than the rigidity of the deformation of the buffer elastic support 13; further, in this embodiment, the buffer member 1 is provided with a connecting bolt hole 122a for connecting with the vibration generating body, and the buffer member 1 is connected to the vibration generating body by means of a bolt passing through the connecting bolt hole 122a.

[0073] Among them, the buffer connecting seat 12 has relatively high rigidity and small deformation range because it bears more support to support the weight of the compressor and plays a part in shock absorption. The buffer elastic support 13 has relatively low rigidity and large deformation range to better achieve shock absorption and disperse the force. At the same time, combined with the above material properties, the corresponding installation structure is matched. The buffer connecting seat 12 adopts the above-mentioned bottom-up installation snap-fit ​​method to increase installation stability and provide reliable support. The buffer elastic support 13 adopts the compression snap-fit ​​installation method, and its flexibility can reduce the number of installation parts to achieve rapid installation.

[0074] To solve the above problems, such as Figure 1 as well as Figure 2 As shown, this utility model also provides an oxygen generator, comprising:

[0075] The aforementioned shock absorption and buffer structure;

[0076] The compressor 3 is installed in the mounting groove 113. The vibration generated by the compressor 3 during operation is transmitted to the buffer elastic support 13 and the buffer connecting seat 12 through the elastic buffer rib 11. The buffer elastic support 13 deforms, and the elastic buffer rib 11 swings up and down periodically at both ends with the buffer connecting seat 12 as the fulcrum.

[0077] To better illustrate the oxygen concentrator of this utility model, the following specific application will be used as an example: The oxygen concentrator of this utility model adopts the above-mentioned shock-absorbing and buffering structure to mitigate the vibration of the compressor 3, the main vibration source in the equipment. This improves the operational stability and reliability of the oxygen concentrator, protects other tightly fitted internal components, reduces noise, enhances user experience, and extends its service life. It can be seen that the shock-absorbing and buffering structure and oxygen concentrator of this utility model, through the combined design of the elastic buffer ribs 11, the buffer connecting seat 12, and the buffer elastic support column 13, utilize the "seesaw" type shock-absorbing structure to effectively dissipate the vibration of the compressor 3. This solves the problems of insignificant shock absorption effect and low vibration energy dissipation efficiency caused by the use of traditional shock-absorbing structures in existing oxygen concentrators.

[0078] In some possible embodiments of this utility model, such as Figure 1 , Figure 2 As shown in Figure 5, the buffer 1 is arranged at an angle to provide space for the piping layout on the oxygen concentrator. Its advantage is that by tilting the buffer 1 at a specific angle, it can better accommodate the piping layout inside the oxygen concentrator, avoid interference, and ensure the normal operation of the equipment.

[0079] In some possible embodiments of this utility model, such as Figure 1 , Figure 2 As shown in Figure 5, the oxygen concentrator also includes a molecular sieve barrel 4, with the shock-absorbing bracket 2 straddling the molecular sieve barrel 4, and a space between the bracket and the molecular sieve barrel 4 for isolating the vibration of the compressor 3. Its beneficial effect is that this design can effectively isolate the impact of the vibration generated by the compressor 3 on the molecular sieve barrel 4, preventing vibration from being transmitted to the molecular sieve barrel 4, thereby protecting the structure and performance of the molecular sieve barrel 4, avoiding molecular sieve failure or damage due to vibration, and ensuring the normal oxygen production function of the oxygen concentrator; furthermore, in this embodiment, the oxygen concentrator also includes a base frame 5, with the molecular sieve barrel 4 fixed to the base frame 5, and the shock-absorbing bracket 2 also fixed to the base frame 5. A certain gap is provided between the molecular sieve barrel 4 and the shock-absorbing bracket 2 to avoid direct transmission of vibration. Further, in this embodiment, as... Figure 5 As shown, the angle between the line connecting the center of the positioning hole 212 and the center of the shock-absorbing hole 222a and the perpendicular direction of the side of the base frame 5 is α. The size of the angle α can be adjusted according to the pipeline layout of the oxygen generator. It should also be noted that the centers of the two shock-absorbing holes 222a and the positioning hole 212 are on the same straight line, so as to ensure that the elastic buffer rib 11 can dissipate the impact force by using a "seesaw" type shock-absorbing structure.

[0080] In summary, the shock-absorbing and buffering structure and oxygen generator of this invention have the following advantages:

[0081] 1. Seesaw-style shock absorption design:

[0082] By utilizing the up-and-down swinging of both ends of the elastic buffer rib 11, the impact force is converted into controllable motion, and the impact energy is dissipated through the deformation of the buffer elastic support 13, effectively reducing the peak impact effect.

[0083] 2. Stable connection between buffer component 1 and shock absorber bracket 2:

[0084] The buffer connector 121 of the buffer connector 12 engages with the positioning groove 211 of the shock absorber bracket 2, and the buffer connector abutment 122 connects with the positioning hole 212, ensuring that the buffer component 1 is stably fixed and improving the reliability and stability of the shock absorber structure.

[0085] 3. Limiting design of the buffer elastic support 13:

[0086] The damping cavity 221 and damping cover 222 of the damping seat 22 limit the range of motion of the buffer elastic support 13, prevent excessive displacement or detachment, and provide additional damping effect.

[0087] 4. Multi-directional force dispersion of the spherical buffer section 132:

[0088] The spherical buffer section 132 in the middle of the buffer elastic support 13 quickly disperses the impact force and transmits it to the shock absorber bracket 2 through the shock absorber seat 22, thereby reducing the peak impact and minimizing damage to the components.

[0089] 5. Structural optimization of elastic buffer rib 11:

[0090] The U-shaped connector 112 design gives the elastic buffer rib 11 better elasticity and toughness, and the mounting groove 113 provides a stable mounting position for the vibration generating body.

[0091] 6. Synergistic effect of multiple buffer components 1:

[0092] The use of multiple buffer components 1 provides a more comprehensive and uniform buffering effect for the main body of vibration generation, further reducing the impact of vibration and improving the vibration reduction performance and operational stability of the equipment.

[0093] 7. Adaptive Design:

[0094] The buffer component 1 can be tilted at a specific angle to adapt to the internal piping layout of the equipment, avoid interference, and ensure normal operation.

[0095] 8. Applications in oxygen concentrators:

[0096] In oxygen concentrators, the shock-absorbing and buffering structure effectively reduces compressor vibration, protects internal components, reduces noise, improves user experience, and extends equipment lifespan.

[0097] This utility model's shock-absorbing and buffering structure, through the combined design of elastic buffer ribs 11, buffer connecting seats 12, and buffer elastic support columns 13, effectively bears the weight of the vibrating main body. When vibration occurs, the swinging of the elastic buffer ribs 11 and the deformation of the buffer elastic support columns 13 dissipate impact energy, reducing the peak impact effect. This "seesaw"-like shock-absorbing design converts impact force into controllable motion and gradually dissipates it, effectively reducing the impact of vibration on surrounding components and improving equipment stability and service life. Its application in oxygen concentrators significantly improves operational stability and reliability, reduces noise, enhances user experience, and extends equipment lifespan.

[0098] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0099] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
