Description

Technical Field

[0001] The present invention relates to the technical field of booster pumps, and particularly relates to a booster pump assembly and a water purifier with shock absorption and noise reduction functions. Background Art

[0002] A booster pump is a pump used for boosting pressure, and its applications mainly include boosting pressure for water heaters, low water pressure in high-rise buildings, saunas, showers, etc., boosting pressure for the uppermost floors of apartments where water pressure is insufficient, boosting pressure for reverse osmosis water purifiers, etc. However, the booster pump generates noise and vibration during use.

[0003] Chinese Patent with Publication No. CN219639031U discloses a noise reduction support structure for a water purifier booster pump, which includes a pair of half-hoop components with the same structure and mirror-image settings. The half-hoop component includes a left half-hoop and a right half-hoop, and the left half-hoop and the right half-hoop are connected by a first fastener at the top to form an arched lifting structure; each half-hoop component includes an integrally provided booster pump fixed shell and a whole machine fixed footrest. The booster pump fixed shell is arc-shaped, and the whole machine fixed footrest is in a "Ji" shape; the shock absorption component includes a T-head rubber pad and a first shock absorption spring sleeved on the T-head rubber pad.

[0004] However, during the use of the above-mentioned booster pump, the booster pump still vibrates violently, and the shock absorption device cannot effectively disperse the force. Long-term vibration will cause impacts and looseness of the support structure, thereby reducing the noise reduction effect of the booster pump. Summary of the Invention

[0010] Preferably, the noise reduction assembly further includes a base, a first sealing ring, a second sealing ring, a plurality of side tubes, and a sound-absorbing cotton. The base is fixedly connected to the bottom of the outer tube and is fixedly connected to the chassis. The first sealing ring is arranged inside one end of the outer tube close to the driving motor. The second sealing ring is fixedly connected inside the other end of the outer tube far from the first sealing ring. The plurality of side tubes respectively connect the first sealing ring and the second sealing ring to the nearest extrusion sheet. The sound-absorbing cotton is arranged inside the outer tube.

[0011] Preferably, the first sealing ring and the second sealing ring are respectively composed of a circular ring and a side piece ring. A ring cavity is provided inside the circular ring and is connected to the extrusion sheet. The side piece ring is fixedly connected to the side of the circular ring far from the shock-absorbing assembly. The side piece ring is inclined and made of an elastic material and is in extrusion contact with the boosting module.

[0012] Preferably, the side of the liquid cavity inside the extrusion sheet is set to be arc-shaped, and a plurality of arc-shaped protruding strips are provided on both sides of the extrusion sheet. A plurality of inner grooves are provided on the side of the extrusion sheet close to the boosting module. The cross-section of the inner groove is V-shaped, and the inner grooves on both sides are symmetrically arranged.

[0013] Preferably, a fixing assembly is provided below the driving motor. The fixing assembly is arranged below the chassis and is used for shock absorption of the driving motor.

[0014] Preferably, the fixing assembly includes a bottom box, a fixing plate, a first magnetic plate, a second magnetic plate, and four elastic columns. An installation opening is provided on the chassis. The bottom box is fixedly installed below the chassis. The driving motor is fixedly connected to the fixing plate by bolts. The first magnetic plate is fixedly connected below the fixing plate through four telescopic fixing columns. The second magnetic plate is fixedly installed at the bottom of the bottom box, and the magnetic poles of the side of the second magnetic plate close to the first magnetic plate are the same. The four elastic columns are fixedly connected to the four corners of the first magnetic plate and the second magnetic plate.

[0015] Preferably, a liquid guiding assembly is provided between the first magnetic plate and the second magnetic plate. The liquid guiding assembly is used to guide liquid into the first sealing ring to increase the volume of the first sealing ring.

[0016] 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 in the shape of a disc. 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 to be connected to the first sealing ring.

[0017] Preferably, two limiting tubes are fixedly connected to the elastic liquid sac. The two limiting tubes are arranged vertically and pass through the first magnetic plate. A bayonet is arranged at the upper end of the limiting tube for fixing bolts.

[0018] A water purifier includes the above-mentioned pressure boosting pump assembly for shock absorption and noise reduction.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. When the pressure boosting module vibrates, it will impact and squeeze the squeezing piece at the swinging position. The impact force generated by the vibration enters the shock-absorbing liquid inside, and at the same time, the shock-absorbing liquid inside the squeezing piece is introduced into the squeezing pieces on both sides through the connecting pipe, so as to disperse the generated impact force, thereby reducing the vibration amplitude of the pressure boosting module.

[0021] 2. Connected by the wavy connecting strip, when noise is generated, during the noise propagation process, the wavy connecting strip can block and cancel the sound multiple times, thereby reducing the outward propagation of noise and achieving the effect of noise reduction.

[0022] 3. By contacting the pressure boosting module through the first sealing ring and the second sealing ring on both sides, it can be ensured that the pressure boosting module does not contact the outer tube during vibration. At the same time, the first sealing ring and the second sealing ring are in close contact with the side of the outer tube, avoiding the generation of gaps and preventing the noise generated by the pressure boosting module from being transmitted out from both sides of the outer tube.

[0023] 4. The squeezing piece is the position where the shock-absorbing component contacts the pressure boosting module. When the pressure boosting module vibrates during operation, due to the V-shaped inner groove inside the squeezing piece, multiple layers of resistance can be formed inside, so as to achieve a good shock-absorbing effect in a relatively small space. At the same time, the inner groove can absorb the generated noise. When the noise propagates 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.

[0024] 5. Through the repulsive force shock-absorbing structure, the wear caused during shock absorption by mechanical components is avoided, ensuring the shock-absorbing effect and service life. At the same time, a large amount of noise generated by mechanical components during shock absorption is avoided, ensuring the overall quiet effect.

[0025] 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;

[0026] 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 implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0038] Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present invention are only for the convenience of clear narration, rather than to limit the scope of implementation of the present invention. The change or adjustment of their relative relationship, without substantial change in technical content, should also be regarded as the scope of implementation of the present invention.

[0039] Referring to Figures 1-9 , a supercharging pump assembly for shock absorption and noise reduction, comprising: a chassis 1, a drive motor 2 installed on the chassis 1, and a supercharging module 3 arranged at the working end of the drive motor 2. A noise reduction component 4 is arranged on the chassis 1, and the noise reduction component 4 is arranged on the supercharging module 3 for noise reduction of the supercharging module 3;

[0040] The noise reduction component 4 includes an outer tube 41, and the outer tube 41 is sleeved on the supercharging module 3;

[0041] An inner part of the outer tube 41 is provided with a shock absorption component 5. The shock absorption component 5 includes a plurality of extrusion sheets 51, a plurality of connecting pipes 52 and a plurality of connecting bars 53. The plurality of extrusion sheets 51 are annularly arranged on the inner side of the outer tube 41. A liquid cavity is arranged inside the extrusion sheet 51. The plurality of connecting pipes 52 connect two adjacent extrusion sheets 51 to form a shock absorption ring. The plurality of shock absorption rings are equidistantly arranged on the inner wall of the outer tube 41. The plurality of connecting bars 53 are fixedly connected between two adjacent shock absorption rings. The plurality of connecting bars 53 are arranged in parallel, and the cross section of the connecting bar 53 is wavy.

[0042] In the embodiments applying the above technical solutions, when the pressurization module 3 performs the water pumping and pressurization operation, the water flow will impact and enter the interior of the pressurization module 3, thereby causing noise inside the pressurization module 3 and also causing vibration of the pressurization module 3. After the pressurization module 3 is installed, the shock-absorbing liquid is filled sufficiently inside the cavity extrusion sheet 51. When the pressurization module 3 vibrates, it will impact and extrude the extrusion sheet 51 at the swinging position. The impact force generated by the vibration enters the shock-absorbing liquid, and at the same time, the shock-absorbing liquid inside the extrusion sheet 51 is introduced into the extrusion sheets 51 on both sides through the connecting pipe 52, spreading the generated impact force, thereby reducing the vibration amplitude of the pressurization module 3. Meanwhile, the interior is connected by the wavy connecting strip 53. When noise is generated, during the propagation of the noise, the wavy connecting strip 53 can block and cancel the sound multiple times, thereby reducing the outward propagation of the noise and achieving the noise reduction effect.

[0043] The present invention reduces the vibration generated during pressurization and improves the noise reduction effect at the same time.

[0044] The preferred technical solution in this embodiment:

[0045] Refer to Figures 4-6 As shown, the 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 a sound-absorbing cotton 46. The base 42 is fixedly connected to the bottom of the outer pipe 41 and is fixedly connected to the bottom frame 1. The first sealing ring 43 is arranged inside one end of the outer pipe 41 close to the driving motor 2. The second sealing ring 44 is fixedly connected to the inside of the other end of the outer pipe 41 away from the first sealing ring 43. The plurality of side pipes 45 respectively communicate 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 pipe 41;

[0046] The first sealing ring 43 and the second sealing ring 44 are respectively composed of a circular ring and a side piece ring. An annular cavity is arranged inside the circular ring and is communicated with the extrusion sheet 51. The side piece ring is fixedly connected to the side of the circular ring away from the shock-absorbing component 5. The side piece ring is inclined and made of an elastic material and is in extrusion contact with the pressurization module 3.

[0047] During the installation process, the pressurization module 3 does not contact the inner wall of the outer pipe 41. When the pressurization module 3 performs pressurization treatment, due to the impact of the water flow, the pressurization module 3 will shake. By contacting the pressurization module 3 through the first sealing ring 43 and the second sealing ring 44 on both sides, it can be ensured that the pressurization module 3 does not contact the outer pipe 41 during vibration. At the same time, the first sealing ring 43 and the second sealing ring 44 are in close contact with the side of the outer pipe 41, avoiding the generation of gaps and preventing the noise generated by the pressurization module 3 from escaping from both sides of the outer pipe 41.

[0048] Inside the outer tube 41, a sound-absorbing cotton 46 is provided on one side, which can achieve a better sound-absorbing effect and ensure the overall noise reduction effect of the noise reduction component 4.

[0049] Since there is liquid inside the annular cavity inside the ring, and the inclined side piece ring can be in close contact with the pressurization module 3, it ensures the noise reduction seal on the side when the pressurization module 3 vibrates.

[0050] Refer to Figure 5 , the side of the liquid cavity inside the extrusion piece 51 is set to be arc-shaped, and there are multiple arc-shaped raised strips on both sides of the extrusion piece 51. There are multiple inner grooves on the side of the extrusion piece 51 close to the pressurization module 3. The cross-section of the inner groove is V-shaped, and the inner grooves on both sides are symmetrically arranged.

[0051] The extrusion piece 51 is the position where the shock absorption component 5 contacts the pressurization module 3. When the pressurization module 3 vibrates during operation, due to the V-shaped inner groove inside the extrusion piece 51, multiple layers of resistance can be formed inside, so as to achieve a better shock absorption effect in a smaller space.

[0052] At the same time, the inner groove can absorb the generated noise. 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 noise elimination effect.

[0053] Refer to Figures 7-9 , a fixing component 6 is provided below the driving motor 2. The fixing component 6 is arranged below the chassis 1 and is used for the shock absorption of the driving motor 2;

[0054] The fixing component 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. An installation opening is provided on the chassis 1. The bottom box 61 is fixedly installed below the chassis 1. The driving motor 2 is fixedly connected to the fixing plate 62 by bolts. The first magnetic plate 63 is fixedly connected to the lower part of the fixing plate 62 through 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 side of the second magnetic plate 64 close to 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.

[0055] Since the driving motor 2 and the pressurization module 3 are fixed together, when the pressurization module 3 vibrates, it will drive the driving motor 2 to swing, resulting in a swinging force generated at the fixed position of the driving motor 2 due to vibration. Long-term vibration will affect the fixation of the driving motor 2. Through the repulsive force support between the first magnetic plate 63 and the second magnetic plate 64, and the first magnetic plate 63 and the second magnetic plate 64 are supported and fixedly connected through multiple elastic columns 65. When the motor vibrates, the vibration force is removed through magnetic extrusion, ensuring the overall shock absorption effect of the driving motor 2 and avoiding the loosening of the bolts at the connection position.

[0056] 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.

[0057] Reference Figures 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;

[0058] 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.

[0059] 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.

[0060] 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.

[0061] Reference Figure 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.

[0062] 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.

[0063] Reference Figures 1-9, a water purifier, including the above-mentioned pressure boosting pump assembly for shock absorption and noise reduction. After using the pressure boosting pump assembly of the present application, during the use of the entire water purifier, the generated noise is reduced and the vibration amplitude is smaller.

[0064] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
