[0012] Preferably, a liquid guiding component is provided between the first magnetic plate and the second magnetic plate, and the liquid guiding component is used to guide liquid into the interior of the first sealing ring to increase the volume of the first sealing ring.

[0013] Preferably, the liquid guiding assembly includes an elastic liquid sac and an elastic liquid guiding tube, the elastic liquid sac is arranged between the first magnetic plate and the second magnetic plate and is arranged in a circular disc shape, one end of the elastic liquid guiding tube is fixedly connected to the elastic liquid sac, and the other end passes through the first magnetic plate and the outer tube and is connected to the first sealing ring.

[0015] A water purifier comprises the above-mentioned shock-absorbing and noise-reducing booster pump assembly.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When the boost module vibrates, it will impact and squeeze the extrusion sheet at the swinging position. The impact force generated by the vibration enters the shock-absorbing fluid. At the same time, the shock-absorbing fluid inside the extrusion sheet is introduced into the extrusion sheets on both sides through the connecting pipe to diffuse the impact force, thereby reducing the vibration amplitude of the boost module. 2. Connected by wavy connecting strips, when noise is generated, the wavy connecting strips can block and offset the sound multiple times during the noise propagation process, thereby reducing the outward propagation of noise and achieving a noise reduction effect; 3. The first sealing ring and the second sealing ring on both sides contact the boost module to ensure that the boost module does not contact the outer tube when it vibrates. At the same time, the first sealing ring and the second sealing ring are in close contact with the side of the outer tube to avoid gaps and prevent the noise generated by the boost module from being transmitted from both sides of the outer tube; 4. The extrusion sheet is the contact point between the shock-absorbing component and the boost module. When the boost module vibrates during operation, the extrusion sheet can form multiple layers of resistance inside due to the internal V-shaped inner groove, thereby achieving a better shock-absorbing effect in a smaller space. At the same time, the inner groove can absorb the noise generated. When the noise is transmitted inside the inner groove, it will be blocked multiple times, thereby reducing the propagation range of the noise and achieving a better effect of eliminating the noise. 5. The repulsive shock-absorbing structure avoids the wear and tear caused by the use of mechanical components during shock absorption, ensuring the shock absorption effect and service life. At the same time, it avoids the mechanical components from generating a lot of noise during shock absorption, ensuring the overall silent effect; 6. When the vibration amplitude is too large, the entire drive motor will also vibrate greatly. At this time, the first magnetic plate will be close to the second magnetic plate, causing the elastic liquid sac arranged between the first magnetic plate and the second magnetic plate to be squeezed and deformed. The elastic liquid sac can play a certain elastic supporting role, thereby reducing the vibration amplitude of the fixed plate; 7. When the drive motor vibrates greatly, the liquid inside the elastic liquid bag will be squeezed and enter the limit tube, causing the upper end of the limit tube to move upward, supporting the bottom end of the bolt, and applying an axial force to the bolt, thereby preventing the bolt from loosening and ensuring the connection between the drive motor and the fixed plate.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not used to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of the present invention without substantially changing the technical content.

[0020] Reference Figure 1-Figure 9 A booster pump assembly with vibration reduction and noise reduction, comprising: a base frame 1, a driving motor 2 mounted on the base frame 1 and a booster module 3 arranged at the working end of the driving motor 2, a noise reduction assembly 4 is arranged on the base frame 1, and the noise reduction assembly 4 is arranged on the booster module 3 for noise reduction of the booster module 3; The noise reduction component 4 includes an outer tube 41, and the outer tube 41 is sleeved on the boost module 3; A shock absorbing assembly 5 is arranged inside the outer tube 41, and the shock absorbing assembly 5 includes a plurality of extrusion sheets 51, a plurality of connecting tubes 52 and a plurality of connecting strips 53. The plurality of extrusion sheets 51 are arranged in a ring shape on the inner side of the outer tube 41, and a liquid cavity is arranged inside the extrusion sheet 51. The plurality of connecting tubes 52 connect two adjacent extrusion sheets 51 to form a shock absorbing ring. The plurality of shock absorbing rings are arranged equidistantly on the inner wall of the outer tube 41, and the plurality of connecting strips 53 are fixedly connected between two adjacent shock absorbing rings. The plurality of connecting strips 53 are arranged in parallel, and the cross-section of the connecting strip 53 is wavy.

[0021] In the embodiment of the application of the above technical solution, when the boosting module 3 is performing water pumping and pressurizing work, the water flow will collide with the inside of the boosting module 3, thereby causing noise inside the boosting module 3 and causing vibration of the boosting module 3. After the boosting module 3 is installed, the cavity extrusion sheet 51 will be filled with sufficient shock-absorbing fluid. When the boosting module 3 vibrates, the extrusion sheet 51 in the swinging position will be impacted and squeezed, and the impact force generated by the vibration enters the shock-absorbing fluid. At the same time, the shock-absorbing fluid inside the extrusion sheet 51 is introduced into the extrusion sheets 51 on both sides through the connecting pipe 52, and the generated impact force is diffused, thereby reducing the vibration amplitude of the boosting module 3. At the same time, the interior is connected by a wavy connecting strip 53. When noise is generated, the wavy connecting strip 53 can block and offset the sound multiple times during the noise propagation process, thereby reducing the outward propagation of noise and achieving a noise reduction effect.

[0022] The present invention reduces the vibration generated during the supercharging process and improves the noise reduction effect.

[0023] The preferred technical solution in this embodiment is: Reference Figure 4-6The noise reduction component 4 further includes a base 42, a first sealing ring 43, a second sealing ring 44, a plurality of side pipes 45 and sound-absorbing cotton 46. The base 42 is fixedly connected to the bottom of the outer tube 41 and is fixedly connected to the bottom frame 1. The first sealing ring 43 is arranged on the inner side of one end of the outer tube 41 close to the drive motor 2. The second sealing ring 44 is fixedly connected to the inner side of one end of the outer tube 41 away from the first sealing ring 43. The plurality of side pipes 45 respectively connect the first sealing ring 43 and the second sealing ring 44 with the nearest extrusion sheet 51. The sound-absorbing cotton 46 is arranged inside the outer tube 41. The first sealing ring 43 and the second sealing ring 44 are respectively composed of a circular ring and a side plate ring. The circular ring is provided with a ring cavity inside and is connected with the extrusion plate 51. The side plate ring is fixedly connected to the side of the circular ring away from the shock absorbing assembly 5. The side plate ring is inclined and made of elastic material, and is in extrusion contact with the boost module 3.

[0024] During the installation process, the boost module 3 does not contact the inner wall of the outer tube 41. When the boost module 3 is performing the boosting process, the impact of the water flow will cause the boost module 3 to shake. The first sealing ring 43 and the second sealing ring 44 on both sides contact the boost module 3 to ensure that the boost module 3 does not contact the outer tube 41 when it vibrates. At the same time, the first sealing ring 43 and the second sealing ring 44 are in close contact with the sides of the outer tube 41 to avoid gaps and prevent the noise generated by the boost module 3 from being transmitted from both sides of the outer tube 41.

[0025] A side of sound-absorbing cotton 46 is arranged inside the outer tube 41 , which can achieve a good noise reduction effect and ensure the overall noise reduction effect of the noise reduction component 4 .

[0026] Since the inner ring cavity of the circular ring is provided with liquid, and the obliquely arranged side plate ring can be in close contact with the boosting module 3, the noise reduction seal on the side of the boosting module 3 is ensured when the boosting module 3 vibrates.

[0027] Reference Figure 5 The side of the liquid cavity inside the extrusion sheet 51 is arranged in an arc shape, and a plurality of arc-shaped raised strips are arranged on both sides of the extrusion sheet 51. A plurality of inner grooves are arranged on one side of the extrusion sheet 51 close to the boost module 3. The cross-section of the inner groove is V-shaped, and the inner grooves on both sides are arranged symmetrically.

[0028] The extrusion sheet 51 is the position where the shock absorbing assembly 5 contacts the boost module 3. When the boost module 3 vibrates during operation, the extrusion sheet 51 can form multiple layers of resistance inside due to the internal V-shaped groove, thereby achieving a better shock absorbing effect in a smaller space.

[0029] At the same time, the inner groove can absorb the noise generated. When the noise is transmitted inside the inner groove, it will be blocked multiple times, thereby reducing the propagation range of the noise and achieving a better effect of eliminating noise.

[0030] Reference Figure 7-9 A fixing assembly 6 is provided below the driving motor 2, and the fixing assembly 6 is provided below the base frame 1 for damping the vibration of the driving motor 2; The fixing assembly 6 includes a bottom box 61, a fixing plate 62, a first magnetic plate 63, a second magnetic plate 64 and four elastic columns 65. A mounting opening is opened on the bottom frame 1. The bottom box 61 is fixedly installed under the bottom frame 1. The drive motor 2 is fixedly connected to the fixing plate 62 by bolts. The first magnetic plate 63 is fixedly connected to the bottom of the fixing plate 62 by four telescopic fixing columns 9. The second magnetic plate 64 is fixedly installed at the bottom of the bottom box 61, and the magnetic poles of the second magnetic plate 64 and the first magnetic plate 63 are the same. The four elastic columns 65 are fixedly connected to the four corners of the first magnetic plate 63 and the second magnetic plate 64.

[0031] Since the drive motor 2 and the boost module 3 are fixed together, when the boost module 3 vibrates, the drive motor 2 is driven to swing, thereby causing the fixed position of the drive motor 2 to generate a swinging force due to the vibration. Long-term vibration will affect the fixation of the drive motor 2. The first magnetic plate 63 and the second magnetic plate 64 are supported and fixed by a plurality of elastic columns 65. When the motor vibrates, the vibration force is removed by magnetic extrusion, thereby ensuring the overall shock-absorbing effect of the drive motor 2 and avoiding the loosening of the bolts at the connection position.

[0032] At the same time, the repulsive shock-absorbing structure avoids the wear and tear caused by the use of mechanical components during shock absorption, ensuring the shock absorption effect and service life. At the same time, it avoids the mechanical components from generating a lot of noise during shock absorption, ensuring the overall quiet effect.

[0033] Reference Figure 8-9 A liquid guide component 7 is provided between the first magnetic plate 63 and the second magnetic plate 64, and the liquid guide component 7 is used to guide liquid into the first sealing ring 43 to increase the volume of the first sealing ring 43; The liquid guiding component 7 includes an elastic liquid sac 71 and an elastic liquid guiding tube 72. The elastic liquid sac 71 is arranged between the first magnetic plate 63 and the second magnetic plate 64 and is arranged in a circular disc shape. One end of the elastic liquid guiding tube 72 is fixedly connected to the elastic liquid sac 71, and the other end passes through the first magnetic plate 63 and the outer tube 41 to be connected to the first sealing ring 43.

[0034] Since the boost module 3 generates different noises and vibrations during different boosting modes, when the vibration amplitude is too large, the entire drive motor 2 will also vibrate greatly. At this time, the first magnetic plate 63 will be close to the second magnetic plate 64, causing the elastic liquid capsule 71 arranged between the first magnetic plate 63 and the second magnetic plate 64 to be squeezed and deformed. The elastic liquid capsule 71 can play a certain elastic supporting role, thereby reducing the vibration amplitude of the fixed plate 62.

[0035] The liquid inside the elastic liquid bag 71 will be squeezed into the first sealing ring 43 through the elastic liquid guide tube 72 due to the extrusion effect, thereby expanding the first sealing ring 43, strengthening the extrusion effect of the first sealing ring 43 on the boost module 3, and strengthening the fixation of the connection position between the boost module 3 and the drive motor 2, thereby reducing the inertial swing of the drive motor 2 caused by vibration.

[0036] Reference Fig. 9 The elastic liquid bag 71 is fixedly connected to two limiting tubes 8, the two limiting tubes 8 are vertically arranged and pass through the first magnetic plate 63, and the upper end of the limiting tube 8 is provided with a bayonet for fixing the bolt.

[0037] The bottom of the bayonet of the limiting tube 8 is in contact with the bolt. When the driving motor 2 vibrates greatly, the liquid inside the elastic liquid bag 71 will be squeezed and enter into the limiting tube 8, causing the upper end of the limiting tube 8 to move upward, supporting the bottom end of the bolt, and applying an axial force to the bolt, thereby preventing the bolt from loosening and ensuring the connection between the driving motor 2 and the fixing plate 62.

[0038] Reference Figure 1-9 A water purifier includes the above-mentioned shock-absorbing and noise-reducing booster pump assembly. After using the booster pump assembly of the present application, the noise generated by the entire water purifier during use is reduced and the vibration amplitude is smaller.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
