A water pump (e.g., a diaphragm pump or a booster pump) is usually installed in the water purifier, so as to enhance the water pressure of the water path system of the water purifier. When the water pump works, the pump body vibrates, so that the vibration noise of the water purifier is overlarge. In the correlation technique, adopt support, damping callus on the sole isotructure to install the water pump in the machine storehouse of purifier to realize the damping effect, but the support isotructure can lead to the volume of water pump assembly and purifier great.

Referring to fig. 1 to 12, the vibration damping assembly of a water pump according to a first aspect of the present invention includes a first vibration damping sleeve 110 and a second vibration damping sleeve 120, wherein the first vibration damping sleeve 110 and the second vibration damping sleeve 120 are suitable for being sleeved on two ends of the water pump 100, so as to reduce the space occupation as much as possible on the basis of reducing the vibration noise, thereby reducing the volume of the water pump assembly and the water purifier.

The water pump 100 may be, but not limited to, a diaphragm pump or a booster pump, etc., and may increase the water pressure in the waterway system of the water purifier, so as to promote the water to flow between the waterway plate and the filtering component, thereby increasing the flow rate of the water purifier, so as to meet the water demand of the user.

The water pump 100 includes a motor and a pump head connected to the motor, and the motor is connected to an external power source and can drive the pump head to generate water pressure. The end at which the motor is located is referred to as the motor end 102 and the end at which the pump head is located is referred to as the pump head end 104. The pump head 104 is formed with a water inlet pipe 106 and a water outlet pipe 108, the water inlet pipe 106 receives water source inside or outside the water circuit board, and after being pressurized by the water pump 100, high-pressure water flows out along the water outlet pipe 108.

In some embodiments, the motor end 102 and the pump head end 104 are disposed opposite to each other, i.e., the water inlet pipe 106, the water outlet pipe 108 and the motor end 102 are on the same axis, and the fixing of the water pump 100 can be achieved by fixing the positions of the two ends of the water pump 100.

An accommodating groove is formed in the first damping sleeve 110 and is suitable for being sleeved outside the motor end 102. The second damping sleeve 120 includes a sleeve 122, and the sleeve 122 is adapted to be sleeved to the outside of the water inlet pipe 106 and the water outlet pipe 108.

It can be understood that the first damping sleeve 110 and the second damping sleeve 120 are made of flexible materials, have elasticity, and can absorb the vibration generated by the water pump 100 during operation, so as to avoid the vibration from being transmitted to the machine shell 200 of the water purifier.

The first damping sleeve 110 is adapted to be sleeved to the motor end 102 to form a main damping of the motor end 102, and the pipe sleeve 122 is adapted to be sleeved to the outer sides of the water inlet pipe 106 and the water outlet pipe 108 to form a main damping of the pump head end 104. When the water pump assembly is installed in the cabinet 200 of the water purifier, the cabinet 200 is connected to the first damping sleeve 110 and the second damping sleeve 120 of the water pump assembly, and does not directly contact the water pump 100. The vibration of the water pump 100 is attenuated after being transmitted to the first damping sleeve 110 and the second damping sleeve 120, and a damping effect can be achieved.

The first damping sleeve 110 and the second damping sleeve 120 are arranged at two ends of the water pump 100 and are tightly attached to the motor end 102 and the pump head end 104, and the first damping sleeve 110 and the second damping sleeve 120 can realize efficient damping without increasing the volume of the water pump assembly.

The sleeve 122 is adapted to fit over the outside of the inlet pipe 106 and the outlet pipe 108 to achieve primary damping of the pump head 104.

In some embodiments, parallel through holes 126 are formed inside the pipe sleeve 122, the outer contour of the pipe sleeve 122 is generally elliptical, the water inlet pipe 106 and the water outlet pipe 108 are suitable for being inserted into the through holes 126 in a one-to-one correspondence manner, and the pipe sleeve 122 wraps the outer sides of the water inlet pipe 106 and the water outlet pipe 108, so that the vibration of the water pump 100 can be prevented from being transmitted to the machine shell 200 along the water inlet pipe 106 and the water outlet pipe 108.

In some embodiments, the second damping sleeve 120 further includes an end sleeve 124, the end sleeve 124 is connected to the sleeve 122, the end sleeve 124 is adapted to be sleeved outside the pump head 104, and can generate a damping effect on the vibration of the pump head 104, so as to prevent the vibration of the pump head 104 from being transmitted to the housing 200, and the end sleeve 124 can form an auxiliary damping effect on the pump head 104.

It will be appreciated that the pump head end 104 is provided with a sleeve 122 and an end sleeve 124, which form the primary and secondary damping of the pump head end 104, respectively, and which provide a dual damping effect to the pump head end 104. The inlet pipe 106 and the outlet pipe 108 extend away from the motor end 102, so that the sleeve 122 is arranged on the side of the end sleeve 124 facing away from the motor end 102.

According to the water pump assembly provided by the embodiment of the utility model, the first damping sleeve 110 and the second damping sleeve 120 are respectively arranged at two ends of the water pump 100, and the first damping sleeve 110 and the second damping sleeve 120 can fix the water pump 100 and can also realize damping of the water pump 100.

In some embodiments, a plurality of first buffer portions 130 are formed inside the first damping sleeve 110, the pipe sleeve 122 and the end sleeve 124, and the volume of the first buffer portions 130 is small, so that the contact area with the water pump 100 can be reduced.

It can be understood that a plurality of first buffer portions 130 are formed inside the first damping sleeve 110, the pipe sleeve 122 and the end sleeve 124, and the plurality of first buffer portions 130 can support and position the water pump 100. The water pump 100 is not in direct contact with the first damping sleeve 110, the pipe sleeve 122 and the end sleeve 124, and the vibration of the water pump 100 is transmitted to the first buffer portion 130 first, and after the first damping of the first buffer portion 130, the second damping of the first damping sleeve 110, the pipe sleeve 122 and the end sleeve 124 is performed, so that the vibration noise of the water pump 100 can be effectively isolated from being transmitted outwards.

The first buffer portion 130 has a small volume, so that the contact area with the water pump 100 is reduced, and the first buffer portion 130 receives only a small amount of vibration of the water pump 100, thereby providing a good vibration damping effect.

In other embodiments, a plurality of second buffer parts 140 are formed on the outer sides of the first damping sleeve 110, the pipe sleeve 122 and the end sleeve 124, and the volume of the second buffer parts 140 is small, so that the contact area with the outside can be reduced.

It is understood that a plurality of second buffer portions 140 are formed at the outer sides of the first damping sleeve 110, the socket 122 and the end sleeve 124, and can support and position the first damping sleeve 110, the socket 122 and the end sleeve 124, respectively. The casing 200 is not in direct contact with the first damping sleeve 110, the pipe sleeve 122 and the end sleeve 124, the vibration of the water pump 100 is transmitted to the first buffering portion 130 first, passes through the first damping of the first buffering portion 130, then passes through the second damping of the first damping sleeve 110, the pipe sleeve 122 and the end sleeve 124, and then passes through the second buffering portion 140 for three times of damping, and finally is transmitted to the casing 200, so that the vibration of the water pump 100 can be effectively isolated.

It should be noted that the second buffer portion 140 has a small volume, reduces the contact area with the outside, and the second buffer portion 140 receives only a small portion of vibration, thereby having a good vibration damping effect.

In some embodiments, the first cushioning portion 130 is a flexible rib or a flexible boss, and the second cushioning portion 140 is a flexible rib or a flexible boss.

In the case that the first buffer portion 130 and the second buffer portion 140 are flexible bosses, the flexible bosses are spaced apart from each other, so that the water pump 100 can be supported, positioned, and damped.

Under the condition that the first buffer part 130 and the second buffer part 140 are flexible ribs, a plurality of flexible ribs are arranged in parallel, and the intervals between the flexible ribs can be the same or different, so that the water pump 100 can be supported, positioned and damped.

The first gap 132 is formed between two adjacent first buffer portions 130, the second gap 142 is formed between two adjacent second buffer portions 140, and the amplitude of the water pump 100 is smaller than the first gap 132 and the second gap 142.

It is understood that the water pump 100 has a certain amplitude when vibrated, thereby deforming the first and second buffering parts 130 and 140. When the amplitude of the water pump 100 is smaller than the first gap 132 and the second gap 142, the adjacent two first buffer portions 130 and the adjacent two second buffer portions 140 do not interfere with each other after being deformed, which is beneficial to improving the vibration reduction effect of the water pump assembly.

In some embodiments, the first buffer portion 130 corresponds to the position of the second gap 142, and the second buffer portion 140 corresponds to the position of the first gap 132, i.e., the first buffer portion 130 and the second buffer portion 140 are disposed in an offset manner.

It can be understood that the vibration of the water pump 100 is transmitted to the first buffer portion 130, passes through the first buffer portion 130 for primary vibration reduction, passes through the first vibration reduction sleeve 110, the pipe sleeve 122 and the end sleeve 124 for secondary vibration reduction, passes through the second buffer portion 140 for tertiary vibration reduction, and is transmitted to the housing 200, so as to effectively isolate the vibration noise of the water pump 100. When the first buffer portion 130 corresponds to the second gap 142 and the second buffer portion 140 corresponds to the first gap 132, direct vibration transmission does not occur between the first buffer portion 130 and the second buffer portion 140, so that a propagation path of vibration is increased, the amplitude of vibration is effectively reduced, and the silence of the water pump assembly can be realized.

The first damping sleeve 110 is suitable for being sleeved to the outer side of the motor end 102, and the second damping sleeve 120 is suitable for being sleeved to the outer side of the pump head end 104, so that a damping effect can be generated on circumferential vibration of the water pump 100.

In some embodiments, an end surface of the first damping sleeve 110 facing away from the second damping sleeve 120 and an end surface of the second damping sleeve 120 facing away from the first damping sleeve 110 are each provided with a third buffer 150, and the third buffer 150 is adapted to absorb axial vibration of the water pump 100.

It will be appreciated that the first damping sleeve 110 may absorb circumferential vibrations of the motor end 102, the sleeve 122 may absorb circumferential vibrations of the inlet pipe 106 and the outlet pipe 108, and the end sleeve 124 may absorb circumferential vibrations of the pump head end 104. When the third buffer portion 150 is disposed in the axial direction from the motor end 102 to the pump head end 104, the third buffer portion 150 can absorb axial vibration of the water pump 100, so as to form a three-way vibration damping effect.

It can be understood that the first damping sleeve 110 and the second damping sleeve 120 are made of flexible materials, have elasticity, and can absorb the vibration generated by the water pump 100 during operation, so as to avoid the vibration from being transmitted to the machine shell 200 of the water purifier.

The first damping sleeve 110 is sleeved on the motor end 102 to form a main damping of the motor end 102, and the pipe sleeve 122 is sleeved on the outer sides of the water inlet pipe 106 and the water outlet pipe 108 to form a main damping of the pump head end 104. When the water pump assembly is installed in the machine shell 200 of the water purifier, the machine shell 200 is connected to the first damping sleeve 110 and the second damping sleeve 120 of the water pump assembly, and does not directly contact with the water pump 100. The vibration of the water pump 100 is attenuated after being transmitted to the first damping sleeve 110 and the second damping sleeve 120, and a damping effect can be achieved.

The first damping sleeve 110 and the second damping sleeve 120 are arranged at two ends of the water pump 100 and are tightly attached to the motor end 102 and the pump head end 104, and the first damping sleeve 110 and the second damping sleeve 120 can realize efficient damping without increasing the volume of the water pump assembly.

The sleeve 122 is sleeved outside the water inlet pipe 106 and the water outlet pipe 108, so that main vibration reduction of the pump head end 104 can be realized.

In some embodiments, two parallel through holes 126 are formed in the pipe sleeve 122, the outer contour of the pipe sleeve 122 is generally elliptical, the water inlet pipe 106 and the water outlet pipe 108 are correspondingly arranged in the two through holes 126 one by one, and the pipe sleeve 122 is wrapped on the outer sides of the water inlet pipe 106 and the water outlet pipe 108, so that the vibration of the water pump 100 can be prevented from being transmitted to the housing 200 along the water inlet pipe 106 and the water outlet pipe 108.

In some embodiments, the second vibration damping sleeve 120 further includes an end sleeve 124, the end sleeve 124 is sleeved outside the pump head 104, and can generate a damping effect on the vibration of the pump head 104, so as to prevent the vibration of the pump head 104 from being transmitted to the casing 200, and the end sleeve 124 can form an auxiliary vibration damping effect on the pump head 104.

It will be appreciated that the pump head end 104 is provided with a sleeve 122 and an end sleeve 124, which respectively form a primary damping and a secondary damping of the pump head end 104, and thus can provide a double damping effect to the pump head end 104. The inlet pipe 106 and the outlet pipe 108 extend away from the motor end 102, so that the sleeve 122 is arranged on the side of the end sleeve 124 facing away from the motor end 102.

According to the water pump assembly provided by the embodiment of the utility model, the first damping sleeve 110 and the second damping sleeve 120 are respectively arranged at two ends of the water pump 100, and the first damping sleeve 110 and the second damping sleeve 120 can fix the water pump 100 and can also realize damping of the water pump 100.

In some embodiments, the diameter of the cavity within the sump 210 is slightly larger than the diameter of the pump head end 104 by 4 to 6 mm.

It will be appreciated that the cavity in the sump 210 is slightly larger than the water pump assembly, and does not interfere with the installation of the water pump assembly, but the cavity volume conforms to the external profile of the water pump assembly.

It can be understood that the first damping sleeve 110 is of a flexible structure, and when the first damping sleeve is assembled in a small interference manner, the first damping sleeve can support the motor end 102 and the machine chamber 210, and can also achieve a damping effect under the condition that the water pump 100 is kept in a stable position.

it will be appreciated that the sleeve 122 and the end sleeve 124 are flexible structures, and when the pump head 104 is assembled in a small interference fit, they can support the pump head 104, and when the pump head 104 is kept in a stable position, they can also achieve a vibration damping effect.

In summary, according to the vibration damping assembly of the water pump, the water pump assembly and the water purifier provided in the embodiments of the present invention, the vibration damping assembly of the water pump includes the first vibration damping sleeve 110 and the second vibration damping sleeve 120, the first vibration damping sleeve 110 is suitable for being sleeved to the outside of the motor end 102 of the water pump 100 to achieve vibration damping of the motor end 102, the second vibration damping sleeve 120 includes the end sleeve 124 and the pipe sleeve 122, the pipe sleeve 122 is suitable for being sleeved to the outside of the water inlet pipe 106 and the water outlet pipe 108, the end sleeve 124 is suitable for being sleeved to the outside of the pump head end 104, two parallel through holes 126 are formed in the pipe sleeve 122, and the water inlet pipe 106 and the water outlet pipe 108 are suitable for being inserted into the two through holes 126 in a one-to-one correspondence. The first damping sleeve 110 and the second damping sleeve 120 occupy a small space, which is beneficial to reducing the volume of the damping structure.

Under the condition that the second vibration attenuation sleeve 120 comprises the end sleeve 124, the end sleeve 124 is sleeved on the outer side of the pump head end 104, so that a damping effect can be generated on the vibration of the pump head end 104, the vibration of the pump head end 104 is prevented from being transmitted to the casing 200, and the end sleeve 124 forms auxiliary vibration attenuation. The sleeve 122 and the end sleeve 124 are disposed at the pump head end 104, and respectively form a main damping effect and an auxiliary damping effect of the pump head end 104, so that a dual damping effect can be formed on the pump head end 104. The water inlet pipe 106 and the water outlet pipe 108 extend away from the motor end 102, so that the pipe sleeve 122 is arranged on the side of the end sleeve 124 facing away from the motor end 102.

In the case where the plurality of first buffer portions 130 are formed inside the first damping sleeve 110, the sleeve 122, and the end sleeve 124, the first buffer portions 130 have a small volume, so that a contact area with the water pump 100 can be reduced, and the plurality of first buffer portions 130 can support and position the water pump 100. The water pump 100 is not in direct contact with the first damping sleeve 110, the pipe sleeve 122 and the end sleeve 124, and the vibration of the water pump 100 is transmitted to the first buffer portion 130 first, and after the first damping of the first buffer portion 130, the second damping of the first damping sleeve 110, the pipe sleeve 122 and the end sleeve 124 is performed, so that the vibration of the water pump 100 can be effectively isolated from being transmitted to the outside.

It should be noted that the first buffer 130 has a small volume, reduces the contact area with the water pump 100, and the first buffer 130 receives only a small amount of vibration of the water pump 100, thereby having a good vibration damping effect.

When the plurality of second buffer portions 140 are formed on the outer sides of the first damping sleeve 110, the sleeve 122, and the end sleeve 124, the second buffer portions 140 themselves have a small volume, and thus the contact area with the outside can be reduced. A plurality of second buffer parts 140 are formed outside the first damping sleeve 110, the socket 122 and the end sleeve 124, and can support and position the first damping sleeve 110, the socket 122 and the end sleeve 124, respectively. The casing 200 is not in direct contact with the first damping sleeve 110, the pipe sleeve 122 and the end sleeve 124, the vibration of the water pump 100 is transmitted to the first buffering portion 130 first, passes through the first damping of the first buffering portion 130, then passes through the second damping of the first damping sleeve 110, the pipe sleeve 122 and the end sleeve 124, and then passes through the second buffering portion 140 for three times of damping, and finally is transmitted to the casing 200, so that the vibration of the water pump 100 can be effectively isolated.

It should be noted that the second buffer portion 140 has a small volume, reduces the contact area with the outside, and the second buffer portion 140 receives only a small portion of vibration, thereby having a good vibration damping effect.

In the case that the first buffer portion 130 and the second buffer portion 140 are flexible bosses, the flexible bosses are spaced apart from each other, so that the water pump 100 can be supported, positioned, and damped.

In the case where the first buffer part 130 and the second buffer part 140 are flexible ribs, the flexible ribs may be arranged in parallel, and the intervals between the flexible ribs may be the same or different.

In the case where the first gap 132 is provided between two adjacent first buffer portions 130 and the second gap 142 is provided between two adjacent second buffer portions 140, the amplitude of the water pump 100 is smaller than the first gap 132 and the second gap 142. The water pump 100 may shake when vibrated, and thus the first and second buffering parts 130 and 140 may be deformed. When the amplitude of the water pump 100 is smaller than the first gap 132 and the second gap 142, the two adjacent first buffer portions 130 and the two adjacent second buffer portions 140 do not interfere with each other after being deformed, which is beneficial to improving the vibration reduction effect of the water pump assembly.

Under the condition that the first buffer portion 130 corresponds to the position of the second gap 142 and the second buffer portion 140 corresponds to the position of the first gap 132, the vibration of the water pump 100 is firstly transmitted to the first buffer portion 130, passes through the first buffer portion 130 for primary vibration reduction, then passes through the first vibration reduction sleeve 110, the pipe sleeve 122 and the end sleeve 124 for secondary vibration reduction, then passes through the second buffer portion 140 for tertiary vibration reduction, and finally is transmitted to the housing 200, so that the vibration of the water pump 100 can be effectively isolated. When the first buffer portion 130 corresponds to the second gap 142 and the second buffer portion 140 corresponds to the first gap 132, direct vibration transmission does not occur between the first buffer portion 130 and the second buffer portion 140, so that the propagation path of vibration is increased, the amplitude of vibration is effectively reduced, and the silence of the water pump assembly can be realized.

Under the condition that the third buffer part 150 is arranged on the side of the first damping sleeve 110, which is back to the pump head end 104, and the side of the second damping sleeve 120, which is back to the motor end 102, the first damping sleeve 110 is arranged on the outer side of the motor end 102 and can absorb circumferential vibration of the motor end 102, the pipe sleeve 122 is arranged on the outer sides of the water inlet pipe 106 and the water outlet pipe 108 and can absorb circumferential vibration of the water inlet pipe 106 and the water outlet pipe 108, and the end sleeve 124 is arranged on the outer side of the pump head end 104 and can absorb circumferential vibration of the pump head end 104. The third buffer part 150 is disposed in the axial direction from the motor end 102 to the pump head end 104, and can absorb the axial vibration of the water pump 100, thereby forming a three-way vibration reduction effect.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
