Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to an installation structure of a booster pump and a water purifier. Background Art

[0002] A water purifier, also known as a water purification machine or water quality purifier, is a water treatment device that deeply filters and purifies water quality according to the usage requirements of water, and can effectively remove harmful substances such as toxins, bacteria, heavy metals, and germs in water. Currently, it is also used by more and more families.

[0003] Currently, the large-flow water purifiers on the market require relatively high pressure for water production. Usually, a booster pump is provided in the water circuit to boost the water flow. When the booster pump is working, the motor rotates at a high speed, generating relatively large noise.

[0004] To reduce noise, the booster pump usually uses a rubber pad for vibration reduction and noise reduction, and is then connected and fixed to the mounting frame by bolts. When the locking force of the bolts is too small, the bolts are likely to become loose during the long-term operation of the booster pump. Therefore, the locking force of the bolts is generally relatively large. In the prior art, due to the too large locking force of the bolts for fixing, the rubber pad is over-compressed. At this time, the booster pump and the mounting frame form a hard contact, so that the rubber pad cannot play the role of vibration reduction and noise reduction. Due to the hard contact between the booster pump and the mounting frame, the noise of the machine is relatively large during operation. In addition, in the prior art, there is also a rubber pad sleeved outside the booster pump, and the outer peripheral side of the booster pump is connected to the inner wall of the accommodating cavity of the mounting frame through the rubber pad. In this way, resonance is easily generated between the booster pump and the mounting frame, generating noise and affecting the user experience. Summary of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0031] Referring to "embodiment" or "embodiment manner" herein means that a specific feature, structure or characteristic described in conjunction with the embodiment or embodiment manner may be included in at least one embodiment of the present utility model. The appearance of this phrase in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0032] To reduce the noise of the booster pump in the water purifier, rubber pads are usually used for the booster pump to reduce vibration and noise, and then it is connected and fixed to the mounting frame by bolts. When the locking force of the bolts is too small, the bolts are likely to become loose during the long-term operation of the booster pump. Therefore, the locking force of the bolts is generally on the large side. Often, due to the excessive locking force of the bolts for fixing, the rubber pads are over-compressed. At this time, the booster pump and the mounting frame form a hard contact, so that the rubber pads cannot play the role of reducing vibration and noise. Due to the hard contact between the booster pump and the mounting frame, the noise is relatively large when the machine is running. In addition, in the prior art, there is also a method of sleeving a rubber pad outside the booster pump, so that the outer peripheral side of the booster pump is connected to the inner wall of the accommodating cavity of the mounting frame through the rubber pad. In this way, resonance is easily generated between the booster pump and the mounting frame, resulting in noise and affecting the user experience.

[0033] In view of this, as Figure 1 and 2 shown, this embodiment provides an installation structure of a booster pump, including a mounting frame 100, a booster pump body 200 and two elastic components 300. The upper and lower ends of the booster pump body 200 are respectively connected to the mounting frame 100 through the elastic components 300, and there is a gap between the outer peripheral side of the booster pump body 200 and the mounting frame 100. The mounting frame 100 can be in the shape of a shell or a bracket, and the mounting frame 100 is provided with a booster pump installation position 101. The two axial ends of the booster pump body 200 are respectively connected to the booster pump installation position 101 of the mounting frame 100 through the elastic components 300. The booster pump body 200 is suspended relative to the mounting frame 100 and is only connected to the mounting frame 100 through the upper and lower two elastic components 300. The radial direction of the booster pump body 200 is separated from the mounting frame 100 by an air gap, avoiding resonance caused by the contact between the outer periphery of the booster pump body 200 and the mounting frame 100. When the booster pump is running, through the elasticity of the elastic components 300, vibration can be well absorbed and eliminated, which is beneficial to reducing the noise during the operation of the booster pump and avoiding resonance. There is no direct hard contact between the booster pump and the mounting frame 100, and it is not necessary to lock and install the booster pump and the mounting frame 100, avoiding the problem of hard contact between the booster pump and the mounting frame 100 caused by excessive locking force. Even when the booster pump is working, the operation process of the water purifier can remain quiet and stable, and the user experience is good.

[0034] Specifically, as Figure 2 and Figure 3As shown in the figure, the main body of the mounting frame 100 can be a plastic housing, which has a booster pump mounting position 101 with openings on one or both sides. The upper and lower ends of the booster pump mounting position 101 have limiting walls 102 and 103. The booster pump body 200 is suspended between the upper and lower limiting walls 102 and 103, and the upper and lower ends of the booster pump body 200 are connected to the limiting walls 102 and 103 through elastic components 300. In specific applications, the mounting frame 100 can also be provided with a filter element mounting position and a water storage tank mounting position, which can be respectively arranged on both sides of the booster pump mounting position 101. A filter element component 410 and a drinking water tank component 420 are respectively arranged at the filter element mounting position and the water storage tank mounting position.

[0035] Specifically, the elastic component 300 can include one of a compression spring, a tension spring (extension spring), an elastic airbag, and an elastic rubber block. Alternatively, the elastic component 300 can include at least two of a compression spring, a tension spring, an elastic airbag, and an elastic rubber block.

[0036] For example: As Figure 4 and Figure 5 shown, as a first optional implementation manner, both ends of the booster pump body 200 are respectively connected to the mounting frame 100 through compression springs 310. The compression springs 310 are deformed under pressure, and it can also meet the requirement of bidirectional shock absorption. The elastic components 300 at the upper and lower ends can include one, two, or more compression springs 310. When there are two or more compression springs 310 arranged at the upper and lower ends of the booster pump body 200, the compression springs 310 can be nested, and the free height or spring modulus of the compression springs 310 can be different to meet different shock absorption requirements.

[0037] As a second optional implementation manner, both ends of the booster pump body 200 are respectively connected to the mounting frame 100 through elastic airbags. The elastic airbags are deformed under pressure, and it can also meet the requirement of bidirectional shock absorption. The elastic components 300 at the upper and lower ends can include one, two, or more elastic airbags.

[0038] As a third optional implementation manner, both ends of the booster pump body 200 are respectively suspended from the mounting frame 100 through tension springs. The elastic components 300 at the upper and lower ends can include one, two, or more tension springs. When the tension springs are stretched and deformed, when there are multiple tension springs, the tension springs at the upper and lower ends can be circumferentially evenly distributed, which can meet the requirement of bidirectional shock absorption.

[0039] As a fourth optional implementation manner, both ends of the booster pump body 200 are respectively connected to the mounting frame 100 through elastic rubber blocks. The elastic rubber blocks are deformed under pressure, and it can also meet the requirement of bidirectional shock absorption. A hollow cavity can be arranged inside the elastic rubber blocks at the upper and lower ends to improve the buffering performance of the elastic rubber blocks.

[0040] As a fifth alternative embodiment, as Figure 6 shown, the elastic member 300 includes two compression springs 310 and 320 which are nested and have different elastic moduli. Benefiting from the two compression springs 310 and 320 with different characteristics, even if the vibration frequencies of the booster pump body 200 are different, the two nested compression springs 310 and 320 with different elastic moduli can better eliminate vibration.

[0041] As a fifth alternative embodiment, as Figure 7 shown, the elastic member 300 includes a compression spring 310 and an elastic airbag 330. The elastic airbag 330 has the advantage of being noise-free. The elastic airbag 330 is arranged inside the compression spring 310. The compression spring 310 is respectively in contact with the mounting frame body 100 and the booster pump body 200. The elastic airbag 330 is respectively in contact with the mounting frame body 100 and the booster pump body 200. The compression spring 310 and the elastic airbag 330 cooperate with each other. Even if the vibration frequencies of the booster pump body 200 are different, the compression spring 310 and the elastic airbag 330 can better eliminate vibration.

[0042] In specific applications, compression springs 310 and tension springs can also be respectively arranged at the upper and lower ends of the booster pump body 200. In this way, when the booster pump body 200 vibrates downward, the tension spring at its upper end is deformed by tension, and the compression spring 310 at its lower end is synchronously deformed by compression. When the booster pump body 200 vibrates upward, the compression spring 310 at its upper end is deformed by compression, and the tension spring at its lower end is synchronously deformed by tension. That is, the elastic members 300 at both the upper and lower ends convert vibration into elastic potential energy, which is beneficial to eliminating larger vibrations. Specifically, the elastic member 300 includes a compression spring 310 and a tension spring. The compression spring 310 is sleeved outside the tension spring. The compression spring 310 is respectively in contact with the mounting frame body 100 and the booster pump body 200. The tension spring is respectively hooked on the mounting frame body 100 and the booster pump body 200, and the vibration damping effect is good. Of course, the setting of the elastic member 300 is not limited to the above description.

[0043] Specifically, the compression spring 310 and the tension spring can be cylindrical helical springs or conical springs. The application cost of the cylindrical helical spring is low. The large end of the conical spring is connected to the booster pump body 200, and the small end is connected to the mounting frame body 100. During vibration, the booster pump body 200 can be centered and reset.

[0044] Specifically, the compression spring 310 and the tension spring can be sleeved with plastic pipe sleeves, that is, the spring metal wires of the compression spring 310 and the tension spring are sleeved with plastic pipe sleeves, which is beneficial to avoiding rust and noise.

[0045] Specifically, asFigure 8 As shown, the mounting frame body 100 is provided with a first positioning structure for mounting the elastic member 300. The first positioning structure includes a first annular rib 110. One end of the elastic member 300 is sleeved outside the first annular rib 110, or the elastic member 300 is inserted into the first annular rib 110. The first annular rib 110 is a hollow cylinder with one end open. In specific applications, liquid soft colloid can also be filled inside the first annular rib 110 and the spring can be inserted and embedded in the soft colloid. After the soft colloid solidifies, the vibration reduction and noise reduction effects can be improved, and the soft colloid can be filled between the inner wall of the first annular rib 110 and the outside of the spring, which can effectively absorb radial vibration.

[0046] Specifically, both ends of the booster pump body 200 are provided with a second positioning structure. The second positioning structure includes a second annular rib 120. The elastic member 300 is inserted inside the second annular rib 120 or sleeved outside the second annular rib 120. For example, the elastic member 300 can be a spring, which can be inserted inside the second annular rib 120 to prevent the spring from being misaligned and affecting the vibration reduction and noise reduction effects. In specific applications, liquid soft colloid can also be filled inside the second annular rib 120 and the spring can be inserted and embedded in the soft colloid. After the soft colloid solidifies, the vibration reduction and noise reduction effects can be improved, and the soft colloid can be filled between the inner wall of the first annular rib 110 and the outside of the spring, which can effectively absorb radial vibration. The first annular rib 110 and the second annular rib 120 can be respectively arranged on the limiting walls 102 and 103.

[0047] Specifically, a gasket is arranged between the mounting frame body 100 and the elastic member 300. The gasket includes a hard colloid and a soft colloid. The soft colloid covers the outside of the hard colloid. In this way, on the one hand, it can further absorb axial vibration reduction to improve the noise reduction effect. At the same time, since the mounting frame body 100 generally adopts a plastic shell structure, by setting the structure of the above gasket, the contact between the gasket and the mounting frame body 100 is a surface contact, avoiding the elastic end directly contacting the mounting frame body 100. The hard colloid disperses the axial impact force, and can also ensure the reliability of the mounting structure and avoid damage to the mounting frame body 100 due to long-term stress.

[0048] Specifically, the mounting frame body 100 is provided with a reinforcement structure. The reinforcement structure is arranged in the area where the mounting frame body 100 is connected to the elastic member 300 (that is, the mounting wall opposite to the elastic member 300 and the mounting frame body 100). The reinforcement structure includes a reinforcing rib integrally formed on the mounting frame body 100 or / and a metal sheet embedded in the mounting frame body 100. In specific applications, the elastic member 300 is installed on one side of the mounting wall, and the reinforcing rib can be integrally formed on the other side of the mounting wall to improve the local structural strength at the mounting wall.

[0049] Specifically, the booster pump body 200 is connected with a water inlet pipe and a water outlet pipe, and a buffer and shock absorption sleeve is sleeved on the water inlet pipe or / and the water outlet pipe. The buffer and shock absorption sleeve can be a rubber sleeve or a waterproof sponge sleeve, which can prevent direct contact between the water inlet pipe and the water outlet pipe and the mounting frame 100, thereby generating noise.

[0050] In this embodiment, the booster pump body 200 is separated from the mounting frame 100 (the inner cavity wall of the booster pump mounting position 101) by a gap. The radial vibration of the booster pump body 200 will not be directly transmitted to the mounting frame 100 through the outer periphery of the booster pump body 200, thus avoiding resonance. The vibration is absorbed by the elastic member 300, which is beneficial to reducing noise and providing a better user experience.

[0051] For the installation structure of a booster pump provided in this embodiment, the upper and lower ends of the booster pump body 200 are respectively connected to the mounting frame 100 through the elastic member 300, and there is a gap (air gap) between the outer peripheral side of the booster pump body 200 and the mounting frame 100. The two ends of the booster pump body 200 are respectively connected to the booster pump mounting position 101 of the mounting frame 100 through the elastic member 300. The booster pump body 200 is suspended relative to the mounting frame 100 and is only connected to the mounting frame 100 through the two upper and lower elastic members 300. There is no need to rigidly connect the booster pump body 200 to the mounting frame 100 by screws. The booster pump body 200 is separated from the mounting frame 100 (the inner cavity wall of the booster pump mounting position 101) by a gap, that is, the outer periphery of the booster pump body 200 does not directly contact the mounting frame 100, nor does it contact the mounting frame 100 through an elastic material, which can avoid the radial vibration of the booster pump body 200 being transmitted to the mounting frame 100 and avoid resonance caused by radial contact. In the up and down direction (axial direction) of the booster pump body 200, it is connected to the mounting frame 100 through the elastic member 300. When the booster pump is running, through the elastic acting force of the elastic member 300, the elasticity of the elastic member 300 can well absorb and eliminate vibration, which is beneficial to reducing the noise during the operation of the booster pump and avoiding resonance. Even when the booster pump is working, the operation process of the water purifier can remain quiet and stable, providing a good user experience.

[0052] The present utility model also provides a water purifier, which includes the above installation structure of a booster pump.

[0053] Specifically, the mounting frame 100 is further provided with a filter element component 410 and a water drinking tank component 420. The mounting frame 100 can serve as the housing or the middle frame member of the water purifier, and it can be a plastic part. The booster pump body 200 is spaced between the filter element component 410 and the water drinking tank component 420. The water drinking tank component 420 can be a hot water tank. By arranging the booster pump body 200 to separate the filter element component 410 and the water drinking tank component 420, the temperature of the water drinking tank component 420 is prevented from affecting the operation of the filter element component 410. The mounting frame 100 can serve as the housing of the water purifier or the internal frame of the water purifier.

[0054] In the mounting structure of a booster pump and the water purifier provided by the embodiment of the present invention, both ends of the booster pump body 200 are respectively connected to the booster pump mounting position 101 of the mounting frame 100 through elastic components 300. The booster pump body 200 is suspended relative to the mounting frame 100 and is only connected to the mounting frame 100 through the upper and lower two elastic components 300. A gap is provided between the booster pump body 200 and the mounting frame 100 (the inner cavity wall of the booster pump mounting position 101) to avoid resonance caused by radial contact. In the up and down direction (axial direction) of the booster pump body 200, it is connected to the mounting frame 100 through the elastic components 300. When the booster pump is operating, through the elastic acting force of the elastic components 300, the elastic potential energy can be used to well absorb and eliminate vibrations, which is beneficial to reducing the noise during the operation of the booster pump. Moreover, a gap is provided between the booster pump body 200 and the mounting frame 100 (the inner cavity wall of the booster pump mounting position 101). The radial vibration of the booster pump body 200 will not be directly transmitted to the mounting frame 100 through the outer periphery of the booster pump body 200, avoiding resonance, and the elastic components 300 absorb the vibrations to facilitate noise reduction.
