Description

Technical Field

[0001] The present invention relates to the field of air pumps, and more particularly to a quick-disassembly and assembly sound-absorbing self-locking structure and an annular intake low-noise vortex air pump. Background Art

[0002] Due to its working principle, traditional vortex air pumps often generate relatively large noise during operation. This high noise not only affects the surrounding working environment but also reduces work efficiency and the comfort of employees. Therefore, a sound-absorbing device needs to be provided for the vortex air pump.

[0003] The currently publicly available Chinese patent authorization announcement number CN219711819U indicates that the existing muffler installation form is through screw connection or threading. However, if screw connection is adopted, both disassembly and assembly are rather troublesome, and if threading connection is adopted, it is prone to loosening. The disclosed low-noise vortex air pump includes an air pump body, which is configured to be cylindrical; an air inlet passage, which extends circumferentially around the air pump body for one week; the low-noise vortex air pump includes: a muffler, which is installed on the air pump body; a mounting shell, which is arranged on the air pump body and provides a mounting platform for mounting the muffler; a sealing shell, which is arranged on the mounting shell and is used for sealing the mounting shell; a self-locking structure, which is used for fixing the muffler on the mounting platform; wherein, a part of the surface of the mounting platform penetrates through the air pump body and is connected to the air inlet passage to form a mounting hole for the muffler to be inserted; a limiting platform is formed on the hole wall of the mounting hole; an installation ring corresponding to the limiting platform is sleeved on the outer wall of the muffler; after the installation ring is inserted into the mounting hole, it abuts against the limiting platform, and the installation ring is fixed in the mounting hole through the self-locking structure.

[0004] According to the above patent, the above patent mates the muffler with the installation ring, and then inserts the muffler into the mounting hole and makes the installation ring abut against the limiting platform, so that the muffler is located in the air inlet passage and the installation ring is fixed on the mounting platform through the self-locking structure. However, vibrations will be generated during the operation of the air pump, and the vibrations will be transmitted to the self-locking structure at the connection of the muffler. Especially after long-term use, the self-locking structure may become loose, thus affecting the sound-absorbing effect. Therefore, there is a need for a self-locking structure that enhances the connection sealing performance and stability of the muffler. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, a quick-disassembly and assembly sound-absorbing self-locking structure is provided. Through the close cooperation between the buckle part and the part to be buckled in the self-locking structure, combined with the automatic pressure adjustment function of the pressing part, it is ensured that the muffler is always firmly connected during operation, effectively avoiding loosening problems caused by vibrations or air flow fluctuations. When disassembling, it can be easily disengaged from the buckle part through the unlocking part, improving the disassembly and assembly efficiency and convenience.

[0006] To solve the problems of the existing technology, the present invention provides a quick-disassembly and sound-insulating self-locking structure, which is applied to a vortex air pump. The vortex air pump has an air inlet and an air outlet. Both the air inlet and the air outlet are connected with a silencer through a self-locking structure. The self-locking structure includes a buckle part arranged on the vortex air pump and a buckled part arranged on the silencer and cooperating with the buckle part. Sealing gaskets abutting against the ends of the silencers are provided at both the air inlet and the air outlet. The self-locking structure further includes a pressing part cooperating with the buckle part and an unlocking part cooperating with the buckled part. In the working state of the vortex air pump, the pressing part can automatically press the buckle part to make the contact between the buckle part and the buckled part closer. In the non-working state of the vortex air pump, the unlocking part can allow the buckled part to disengage from the buckle part to disassemble the silencer.

[0007] Preferably, a support is provided at the position corresponding to each air port on the vortex air pump. The pressing part can move on the support in the direction towards the buckle part. The inner wall of the pressing part and the outer wall of the buckle part are provided with mutually cooperating inclined surfaces. When the pressing part acts on the buckle part, the buckle part is in a state of pressing the buckled part.

[0008] Preferably, a first flexible layer capable of contacting the outer wall of the buckle part is provided on the inner wall of the pressing part to effectively reduce the friction force during the relative movement of the pressing part and the buckle part.

[0009] Preferably, a second flexible layer capable of adapting to the buckled part is provided on the inner wall of the buckle part to effectively enhance the indirect pressing ability of the buckle part on the buckled part.

[0010] Preferably, a sliding sleeve capable of driving the pressing part to move is slidably provided on the support. A return spring is provided between the sliding sleeve and the support. When the return spring is not acted on by an external force, the first flexible layer is in an uncompressed state, and at the same time, a gap for the buckle part to adapt to the deformation of the buckled part is formed between the pressing part and the buckle part.

[0011] Preferably, a plurality of the buckle parts are evenly distributed around the corresponding air ports on the support. A buckled part is provided on the silencer corresponding to each buckle part. The gap between every two adjacent buckle parts is the unlocking part. When the silencer is rotated to make the buckled part overcome the second flexible layer and enter the unlocking part, the buckled part is in a disengaged state relative to the buckle part.

[0012] Preferably, a guide rod extends outward along the moving direction of the sliding sleeve on the sliding sleeve. A guide groove capable of slidingly engaging with the guide rod is provided on the silencer. When the guide rod is engaged with the guide groove, the buckled part and the buckle part are in a locked state to prevent the silencer from rotating.

[0013] Preferably, a push plate is provided between two sliding sleeves corresponding to the air outlets, and a pusher is provided on the vortex air pump, which can drive the push plate to move linearly when the vortex air pump is in operation. When the pusher is started, the push plate is in a state of driving the two sliding sleeves to move simultaneously, so that the pressing part moves along with the sliding sleeve and acts on the buckling part.

[0014] Preferably, the pusher is composed of a driving part and a driven part. The driving part is connected to the output end of the vortex air pump, the driven part is connected to the push plate, the driven part can move relative to the driving part, and a driving part is provided on the driving part, which can drive the driven part to move during the movement of the driving part following the output end of the vortex air pump.

[0015] The present invention also provides an annular intake low-noise vortex air pump, which includes a pump body and a vortex impeller arranged therein. An impeller motor is provided on the pump body, and a quick-disassembly, sound-absorbing and self-locking structure as described above is also included.

[0016] The beneficial effects of this application compared with the prior art are as follows:

[0017] 1. Through the close cooperation between the buckling part and the buckled part in the self-locking structure of the present invention, combined with the automatic pressure adjustment function of the pressing part, it is ensured that the muffler always maintains a firm connection during operation, effectively avoiding loosening problems caused by vibration or air flow fluctuations, and also avoiding the high-pressure state of the buckling part and the buckled part for a long time when the air pump is not working, which affects the service life and is difficult to disassemble. At the same time, the pressing of the sealing gasket further improves the gas tightness, reduces the leakage risk, and ensures the energy efficiency of the muffler. When the vortex air pump stops running, the unlocking part provides a quick disassembly mechanism, and the muffler can be quickly replaced or maintained without complex tools. It not only improves the convenience of installation and disassembly, but also significantly enhances the connection reliability and air tightness, providing a strong guarantee for the efficient operation of the vortex air pump;

[0018] 2. Through the inclined surface cooperation between the pressing part and the buckling part of the present invention, and the synergistic effect of the first flexible layer and the second flexible layer, the connection performance between the muffler and the vortex air pump is improved. When the pressing part moves, the first flexible layer effectively reduces the friction force and ensures smooth movement. The second flexible layer in the buckling part enhances the pressing ability on the buckled part through adaptive deformation, ensuring a tight and reliable connection. It not only extends the service life of the buckling part, but also improves the anti-vibration performance of the muffler;

[0019] 3. The present invention ensures the accurate positioning and locking of the muffler during installation through the cooperation of the guide rod and the guide groove, enabling the muffler to be quickly installed and preventing its self-rotation during the working state. When disassembling the muffler, as the guide rod is disengaged from the guide groove and the muffler is rotated, the clamped portion can overcome the second flexible layer and enter the unlocking portion, thereby easily disengaging from the restraint of the buckle portion, making the muffler quickly detachable. This improves the efficiency and convenience of quickly disassembling and assembling the muffler. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0031] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0032] See Figures 1-7 As shown, a quick-disassembly and installation silencing self-locking structure is applied to the vortex air pump 1. The vortex air pump 1 has an air inlet 111 and an air outlet 112. Both the air inlet 111 and the air outlet 112 are connected with a silencer 3 through a self-locking structure 2. The self-locking structure 2 includes a clamping part 21 provided on the vortex air pump 1 and a clamped part 22 provided on the silencer 3 and cooperating with the clamping part 21. Sealing gaskets 1111 abutting against the ends of the silencer 3 are provided at both the air inlet 111 and the air outlet 112. The self-locking structure 2 further includes a pressing part 23 cooperating with the clamping part 21 and an unlocking part 24 cooperating with the clamped part 22. In the working state of the vortex air pump 1, the pressing part 23 can automatically press the clamping part 21 to make the contact between the clamping part 21 and the clamped part 22 closer. In the non-working state of the vortex air pump 1, the unlocking part 24 can allow the clamped part 22 to disengage from the clamping part 21 to disassemble the silencer 3.

[0033] When installing the silencer 3, it is first necessary to ensure that the vortex air pump 1 is in a non-working state. To prevent the internal pressure and air flow from affecting the installation process. Once it is confirmed that the vortex air pump 1 is in a stopped state, the operator holds the silencer 3 and tightly connects it with the vortex air pump 1 through the clamping part 21 and the clamped part 22 in the self-locking structure 2. When the clamping part 21 and the clamped part 22 are successfully clamped, the end of the silencer 3 contacts the sealing gasket 1111 to ensure no gas leakage. At this time, the silencer 3 has formed a firm and safe connection with the vortex air pump 1 during use.

[0034] When the silencer 3 is correctly installed and connected to the vortex air pump 1, the pressing part 23 will be automatically activated during operation. At this time, the pressing part 23 transfers the pressure to the buckling part 21, making the contact between the buckling part 21 and the buckled part 22 on the silencer 3 closer. This ensures a more secure locking between the two, preventing loosening due to vibration and changes in air flow fluctuations.

[0035] Under the action of the pressing part 23, the contact pressure between the buckling part 21 and the buckled part 22 will be continuously maintained. That is, during the actual operation of the vortex air pump 1, the pressing part 23 can provide continuous support to ensure the stability of the silencer 3. By automatically applying appropriate pressure, the pressing part 23 enhances the stability between the silencer 3 and the vortex air pump 1, effectively avoiding the impact of air flow on the silencer 3 and ensuring that the silencer 3 can maintain a stable working state during the efficient operation of the vortex air pump 1.

[0036] During the process of the pressing part 23 applying pressure, the contact between the buckling part 21 and the buckled part 22 is not only closer, but also the sealing gaskets 1111 at the air inlet 111 and the air outlet 112 are better pressed, further ensuring the sealing performance. Effective sealing avoids the risk of gas leakage, guarantees the efficient operation of the silencer 3 throughout the working cycle, and prevents energy efficiency degradation caused by leakage.

[0037] When the vortex air pump 1 stops working, the pressing part 23 will automatically stop applying pressure. At this time, the connection between the silencer 3 and the vortex air pump 1 will automatically maintain a safe and stable state.

[0038] Then, the operator releases the lock between the buckling part 21 and the buckled part 22 through the unlocking part 24. By providing an unlocking mechanism, the buckling part 21 and the buckled part 22 can be separated, avoiding any complex operations during the disassembly process. The operator only needs to perform step-by-step operations to remove the silencer 3 from the vortex air pump 1 to complete the entire disassembly process.

[0039] See Figures 1-7 As shown, a support 4 is provided at each position corresponding to each air port on the vortex air pump 1. The pressing part 23 can move on the support 4 in the direction of the buckling part 21. The inner wall of the pressing part 23 and the outer wall of the buckling part 21 are provided with mutually cooperating inclined surfaces. When the pressing part 23 acts on the buckling part 21, the buckling part 21 is in a state of pressing the buckled part 22.

[0040] When the vortex air pump 1 is running, the pressing part 23 moves on the support 4 in the direction of the buckling part 21, and the mutually cooperating inclined surfaces on its inner wall and the outer wall of the buckling part 21 start to contact and generate a force.

[0041] With the further movement of the pressing part 23, the pressure between the inclined planes gradually increases, prompting the buckle part 21 to deform and exert an additional pressure on the part to be buckled 22, thereby making the connection between the buckle part 21 and the part to be buckled 22 tighter and more secure. It ensures that during the operation of the vortex air pump 1, the connection between the silencer 3 and the vortex air pump 1 can effectively resist the influence of vibration and air flow fluctuations and maintain a stable locked state.

[0042] See Figures 2-7 As shown, a first flexible layer 231 capable of contacting the outer wall of the buckle part 21 is provided on the inner wall of the pressing part 23 to effectively reduce the friction force during the relative movement of the pressing part 23 with respect to the buckle part 21.

[0043] When the pressing part 23 moves on the support 4 and contacts the buckle part 21, the first flexible layer 231 on the inner wall of the pressing part 23 comes into contact with the outer wall of the buckle part 21. Relying on its flexibility and elastic properties, the first flexible layer 231 forms a buffer during the relative movement of the two, effectively reducing the friction force generated by direct contact.

[0044] Through the indirect action of the first flexible layer 231, not only is the movement resistance reduced, but also the wear between the buckle part 21 and the pressing part 23 is reduced, ensuring that the pressing part 23 can apply pressure to the buckle part 21 more smoothly, while extending the service life of the self-locking structure 2.

[0045] See Figures 2-7 As shown, a second flexible layer 211 capable of adapting to the part to be buckled 22 is provided on the inner wall of the buckle part 21 to effectively enhance the indirect pressing ability of the buckle part 21 on the part to be buckled 22.

[0046] When the part to be buckled 22 is inserted into the buckle part 21, the second flexible layer 211 on the inner wall of the buckle part 21 will adapt to the shape of the part to be buckled 22 and fit closely. Through the elastic deformation of the second flexible layer 211, the buckle part 21 can transfer the pressure to the part to be buckled 22 more evenly, thereby effectively enhancing the pressing ability on the part to be buckled 22.

[0047] With the pressure exerted by the pressing part 23 on the buckle part 21, the buckle part 21 can indirectly press the part to be buckled 22 through the second flexible layer 211, and flexibly and evenly transfer the pressing force of the buckle part 21 to the part to be buckled 22 through its own elastic deformation, avoiding wear caused by hard contact. It not only improves the connection stability between the buckle part 21 and the part to be buckled 22, but also ensures that the two maintain a closer contact under the stressed state, further enhancing the reliability of the self-locking structure 2.

[0048] See Figures 2-7As shown, a sliding sleeve 41 capable of driving the pressing part 23 to move is slidably arranged on the support 4. A return spring 42 is arranged between the sliding sleeve 41 and the support 4. When the return spring 42 is not subjected to external force, the first flexible layer 231 is in an uncompressed state, and at the same time, a gap is formed between the pressing part 23 and the buckling part 21 for the buckling part 21 to adapt to the deformation of the part to be buckled 22.

[0049] A flexible protective sleeve 421 for wrapping the return spring 42 therein is arranged between the support 4 and the sliding sleeve 41.

[0050] When the return spring 42 is not subjected to external force, the sliding sleeve 41 maintains its initial position on the support 4. At this time, the first flexible layer 231 is in an uncompressed state, and a certain gap is formed between the pressing part 23 and the buckling part 21. This gap allows the buckling part 21 to adaptively deform and adjust according to the size of the part to be buckled 22.

[0051] At the same time, the flexible protective sleeve 421 between the support 4 and the sliding sleeve 41 wraps the return spring 42 therein, which not only protects the return spring 42 from external interference but also ensures the stability and flexibility of the sliding sleeve 41 when sliding along the support 4. When pressure needs to be applied, the sliding sleeve 41 moves under the action of an external force to overcome the elastic force of the return spring 42, driving the pressing part 23 to approach the buckling part 21 and compressing the first flexible layer 231, thereby realizing the pressure transmission to the buckling part 21.

[0052] See Figures 4-8 As shown, a plurality of the buckling parts 21 are evenly distributed around the corresponding air outlets on the support 4. A part to be buckled 22 is provided corresponding to each buckling part 21 on the silencer 3. The gap between every two adjacent buckling parts 21 is the unlocking part 24. When the silencer 3 is rotated to make the part to be buckled 22 overcome the second flexible layer 211 and enter the unlocking part 24, the part to be buckled 22 is in a disengaged state relative to the buckling part 21.

[0053] When the silencer 3 needs to be disassembled, rotate the silencer 3 to align the part to be buckled 22 with the unlocking part 24 between every two adjacent buckling parts 21. During this process, the part to be buckled 22 needs to overcome the resistance of the second flexible layer 211 and gradually disengage from the restraint of the buckling part 21.

[0054] Since the second flexible layer 211 is elastic, it provides a certain buffering effect when the part to be buckled 22 moves, reducing hard wear. Finally, when the part to be buckled 22 completely enters the unlocking part 24, a disengaged state is formed between the part to be buckled 22 and the buckling part 21, thereby realizing the quick unlocking and separation of the silencer 3.

[0055] See Figures 4-8As shown, a guide rod 411 extends outward along the moving direction of the sliding sleeve 41. A guide groove 31 is provided on the silencer 3, which can be slidably engaged with the guide rod 411. When the guide rod 411 is engaged with the guide groove 31, the locked part 22 and the buckling part 21 are in a locked state to prevent the silencer 3 from rotating.

[0056] When the sliding sleeve 41 moves to engage the guide rod 411 with the guide groove 31 on the silencer 3, the guide rod 411 is firmly embedded along the direction of the guide groove 31. At this time, a tight locking state is formed between the locked part 22 and the buckling part 21, effectively preventing the silencer 3 from rotating during the operation of the vortex air pump 1, and avoiding the loosening or misalignment of the connection between the locked part 22 and the buckling part 21 caused by vibration, thereby improving the stability and reliability of the silencer 3.

[0057] When docking the locked part 22 and the buckling part 21 on the silencer 3, through the cooperation of the guide rod 411 and the guide groove 31, it can also play a guiding role, facilitating the quick installation of the silencer 3.

[0058] See Figure 1 、 Figure 2 、 Figure 9 and Figure 10 As shown, a push plate 5 is provided between two sliding sleeves 41 corresponding to the air outlets. A pusher 51 is provided on the vortex air pump 1, which can drive the push plate 5 to move in a straight line during its operation. When the pusher 51 is started, the push plate 5 is in a state of driving the two sliding sleeves 41 to move simultaneously, so that the pressing part 23 moves along with the sliding sleeve 41 and acts on the buckling part 21.

[0059] When the vortex air pump 1 enters the working state, the pusher 51 is started and drives the push plate 5 to move in a straight line. The push plate 5 is located between two sliding sleeves 41 corresponding to the air outlets, and its movement causes the two sliding sleeves 41 to move in the same direction simultaneously.

[0060] As the sliding sleeve 41 moves, the pressing part 23 moves along with the sliding sleeve 41 and gradually approaches the buckling part 21, and finally acts on the buckling part 21. Through the cooperation between the inner wall of the pressing part 23 and the outer wall of the buckling part 21, the buckling part 21 applies pressure to the locked part 22, thereby realizing the automatic reinforcement and stable locking of the self-locking structure 2 during the operation of the vortex air pump 1.

[0061] See Figure 1 、 Figure 2 、 Figure 9 and Figure 10As shown, the pusher 51 is composed of a driving member 511 and a driven member 512. The driving member 511 is connected to the output end of the vortex air pump 1, the driven member 512 is connected to the push plate 5, the driven member 512 can move relative to the driving member 511, and the driving member 511 is provided with a driving part 5111 that can drive the driven member 512 to move during the movement of the driving member 511 following the output end of the vortex air pump 1.

[0062] The output end of the vortex air pump 1 has a machine shaft 131. The driving member 511 is specifically a disc-shaped structure coaxially connected to the machine shaft 131. The driven member 512 is specifically an annular structure sleeved on the driving member 511. The driving part 5111 is a block structure. The driving part 5111 is slidably arranged on the driving member 511 along its radial direction. There is a chute for the driving part 5111 to slide in between the driving member 511 and the driven member 512. The inner wall of the driven member 512 and the driving part 5111 are provided with mutually cooperating inclined surfaces.

[0063] When the machine shaft 131 rotates to drive the driving member 511 to rotate synchronously, the driving part 5111 moves outward along the chute due to the action of centrifugal force, so that the driven member 512 moves under the push of the driving part 5111, realizing the movement of the push plate 5 to drive the two sliding sleeves 41 at the same time. At this time, the return spring 42 connected between the sliding sleeve 41 and the support 4 is in a stretched state. Furthermore, each muffler 3 is strengthened and locked under the cooperation of the pressing part 23 and the buckling part 21. The higher the rotational speed of the air pump during operation, the greater the vibration generated, and the greater the pressure of the pressing part 23 acting on the buckling part 21. This can not only make the muffler 3 firmly engaged during the operation of the air pump, but also prevent the engaging structure from being in a high-pressure state for a long time when the air pump is not working, which affects the service life and is difficult to disassemble.

[0064] A bearing 52 is provided between the driven member 512 and the push plate 5. When the driving member 511 rotates, since the driving part 5111 is clamped in the chute between the driving member 511 and the driven member 512, the driven member 512 can rotate together, reducing the friction between the driven member 512 and the push plate 5.

[0065] A plurality of the driving parts 5111 are evenly distributed along the circumferential direction of the driving member 511. Buffer layers 5121 for reducing the impact force are provided at the positions of the inner wall of the driven member 512 corresponding to each driving part 5111.

[0066] The driving member 511 can slide on the machine shaft 131. A clamping strip 1311 is provided on the machine shaft 131 along its axial direction. A bayonet matching the clamping strip 1311 is opened on the driving member 511, which can not only realize the rotation of the driving member 511 but also realize the movement of the driving member 511.

[0067] When the operator presses the driven member 512 when the vortex air pump 1 is in an unoperated state, the driving member 511 moves together with the driven member 512, and the push plate 5 follows the driven member 512 to move the guide rods 411 on the two sliding sleeves 41 away from the guide grooves 31 on the corresponding mufflers 3. At this time, the return springs 42 connected between the sliding sleeves 41 and the supports 4 are in a compressed state. Thereby, the locking of the two mufflers 3 is released simultaneously, and the stuck portion 22 can enter the unlocking portion 24 when the muffler 3 is rotated to complete the disassembly.

[0068] A compression spring 1312 is provided between the driving member 511 and the machine shaft 131. When the driven member 512 is pressed, the compression spring 1312 is in a compressed state. When the driven member 512 is released, the compression spring 1312 is in a reset state, which is beneficial to the return of the driving member 511 and ensures the effective cooperation between the driving member 511 and the driven member 512.

[0069] An annular intake low-noise vortex air pump includes a pump body 11 and a vortex impeller 12 disposed therein. An impeller motor 13 is provided on the pump body 11, and also includes a quick-disassembly and assembly soundproofing self-locking structure as described above.

[0070] The machine shaft 131 connecting the driving member 511 is specifically the machine shaft 131 of the impeller motor 13.

[0071] Through the tight cooperation between the buckle portion 21 and the stuck portion 22 in the self-locking structure 2 of the present invention, combined with the automatic pressure adjustment function of the pressing portion 23, it is ensured that the muffler 3 is always firmly connected during operation, effectively avoiding the loosening problem caused by vibration or air flow fluctuation. At the same time, the pressing of the sealing gasket 1111 improves the gas tightness, reduces the leakage risk, and ensures the energy efficiency.

[0072] When the vortex air pump 1 stops, the unlocking portion 24 provides a quick disassembly mechanism, and the muffler 3 can be replaced or maintained without complex tools. The precise positioning of the muffler 3 is ensured through the cooperation between the guide rod 411 and the guide groove 31 to prevent self-rotation. When disassembling, it can be easily separated from the buckle portion 21 through the unlocking portion 24, improving the disassembly and assembly efficiency and convenience.
