A water pump (e.g., a diaphragm pump or a booster pump, etc.) is generally installed in the water purification apparatus, thereby enhancing the water pressure of the waterway system of the water purification apparatus. The pump body can produce vibration when the water pump works to lead to the excessive noise of water purifying equipment vibration. In the related art, the water pump is installed in the machine cabin of the water purifying equipment in a mode of a bracket, a vibration reduction foot pad and the like, so that the vibration reduction effect is achieved, but the water pump assembly and the water purifying equipment are large in size due to the structure of the bracket and the like.
Referring to fig. 1 to 14, a water pump assembly according to an embodiment of the present invention includes a water pump 100, a first damping sleeve 110, and a second damping sleeve 120.
The water pump 100 may be, but not limited to, a diaphragm pump or a booster pump, etc., which may increase the water pressure in the water path system of the water purifying apparatus, promote the water to flow between the water path plate and the filtering part, and further promote the flow rate of the water purifying apparatus, so as to satisfy 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 to 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 a water source inside or outside the waterway 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 end 104 are disposed opposite to each other, i.e., the water inlet pipe 106 and the water outlet pipe 108 are on the same axis with the motor end 102, and the fixing of the water pump 100 can be achieved by fixing the positions of the two ends of the water pump 100.
The first damping sleeve 110 has a receiving groove formed therein and is sleeved outside the motor end 102. The second damping sleeve 120 includes a sleeve 122, the sleeve 122 being disposed over the outside of the inlet pipe 106 and the outlet pipe 108.
It can be appreciated 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 when the water pump 100 works, so as to avoid the vibration from being transmitted to the casing 200 of the water purifying apparatus.
The first damping sleeve 110 is sleeved on the motor end 102 to form main damping of the motor end 102, and the sleeve 122 is sleeved on the outer sides of the water inlet pipe 106 and the water outlet pipe 108 to form main damping of the pump head end 104. When the water pump assembly is installed in the cabinet 200 of the water purifying apparatus, the cabinet 200 is connected to the first damping sleeve 110 and the second damping sleeve 120 of the water pump assembly, and no direct contact with the water pump 100 occurs. Vibration of the water pump 100 is attenuated after being transmitted to the first and second damping sleeves 110 and 120, and thus a damping effect can be achieved.
The first vibration damping sleeve 110 and the second vibration damping sleeve 120 are arranged at two ends of the water pump 100 and are clung to the motor end 102 and the pump head end 104, and the first vibration damping sleeve 110 and the second vibration damping sleeve 120 can realize efficient vibration damping without increasing the volume of the water pump assembly.
The sleeve 122 is sleeved on the outer sides of 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 inside the pipe sleeve 122, the external outline of the pipe sleeve 122 is in an oval shape, the water inlet pipe 106 and the water outlet pipe 108 are arranged in the two through holes 126 in a one-to-one correspondence, the pipe sleeve 122 wraps the outer sides of the water inlet pipe 106 and the water outlet pipe 108, and vibration of the water pump 100 can be prevented from being transmitted to the casing 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, where the end sleeve 124 is sleeved on the outer side of the pump head end 104, so as to generate a damping effect on the vibration of the pump head end 104, prevent the vibration of the pump head end 104 from being transmitted to the casing 200, and the end sleeve 124 can form auxiliary damping for the pump head end 104.
It will be appreciated that the provision of the sleeve 122 and the end sleeve 124 at the pump head end 104, respectively, to provide primary and secondary damping of the pump head end 104, may provide a dual damping effect to the pump head end 104. The inlet tube 106 and the outlet tube 108 extend away from the motor end 102 such that the sleeve 122 is disposed on a side of the end cap 124 facing away from the motor end 102.
According to the water pump assembly provided by the embodiment of the invention, the first vibration damping sleeve 110 and the second vibration damping sleeve 120 are respectively arranged at two ends of the water pump 100, and the first vibration damping sleeve 110 and the second vibration damping sleeve 120 not only can fix the water pump 100, but also can realize vibration damping of the water pump 100.
In some embodiments, the inner sides of the first damping sleeve 110, the sleeve 122 and the end sleeve 124 are formed with a plurality of first buffer parts 130, and the first buffer parts 130 have smaller volume, so that the contact area with the water pump 100 can be reduced.
It is understood that the inner sides of the first damping sleeve 110, the sleeve 122 and the end cap 124 are formed with a plurality of first buffering portions 130, and the plurality of first buffering portions 130 can support and position the water pump 100. The water pump 100 is not in direct contact with the first vibration damping sleeve 110, the sleeve 122 and the end sleeve 124, the vibration of the water pump 100 is firstly transferred to the first buffer part 130, and after primary vibration damping of the first buffer part 130, secondary vibration damping of the water pump 100 can be effectively isolated, and the vibration noise of the water pump 100 is transferred outwards.
The first buffer portion 130 has a small volume, reduces the contact area with the water pump 100, and the first buffer portion 130 receives only a small portion of vibration of the water pump 100, thereby having a good vibration damping effect.
In other embodiments, the outer sides of the first damping sleeve 110, the sleeve 122 and the end sleeve 124 are formed with a plurality of second buffer parts 140, and the second buffer parts 140 have smaller volume, so that the contact area with the outside can be reduced.
It is understood that the outer sides of the first damping sleeve 110, the sleeve 122 and the end cap 124 are formed with a plurality of second buffering portions 140 for supporting and positioning the first damping sleeve 110, the sleeve 122 and the end cap 124, respectively. The casing 200 is not in direct contact with the first vibration damping sleeve 110, the sleeve 122 and the end sleeve 124, the vibration of the water pump 100 is firstly transferred to the first buffer part 130, after primary vibration damping of the first buffer part 130, secondary vibration damping of the first vibration damping sleeve 110, the sleeve 122 and the end sleeve 124, and then tertiary vibration damping of the second buffer part 140, and finally transferred to the casing 200, so that the vibration of the water pump 100 can be effectively isolated.
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 flexible boss and the second cushioning portion 140 is a flexible rib or flexible boss.
In the case where the first buffer portion 130 and the second buffer portion 140 are flexible bosses, a plurality of flexible bosses are provided at intervals, and a supporting, positioning and vibration damping effect can be formed for the water pump 100.
In the case where the first buffer portion 130 and the second buffer portion 140 are flexible ribs, a plurality of flexible ribs may be arranged in parallel, and the intervals between the flexible ribs may be the same or different.
A first gap 132 is formed between two adjacent first buffer portions 130, a 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 can be appreciated that the water pump 100 has a certain amplitude when vibrating, and thus the first buffer portion 130 and the second buffer portion 140 are 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 will 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, that is, the first buffer portion 130 and the second buffer portion 140 are offset.
It can be understood that the vibration of the water pump 100 is transferred to the first buffer portion 130, after the vibration is damped once by the first buffer portion 130, the vibration is damped twice by the first damping sleeve 110, the sleeve 122 and the end sleeve 124, and then damped three times by the second buffer portion 140, and finally transferred to the casing 200, so that the vibration noise 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, no direct vibration transmission occurs 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 silence of the water pump assembly can be achieved.
The first damping sleeve 110 is sleeved on the outer side of the motor end 102, and the second damping sleeve 120 is sleeved on 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, a third buffer portion 150 is disposed on a side of the first damping sleeve 110 facing away from the pump head end 104 and a side of the second damping sleeve 120 facing away from the motor end 102, and the third buffer portion 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 end 104. When the third buffer portion 150 is disposed in the axial direction from the motor end 102 to the pump end 104, the third buffer portion 150 can absorb the axial vibration of the water pump 100, thereby forming a three-way vibration damping effect.
