Description

Technical Field

[0001] This utility model specifically relates to a shock absorption device and a pump body and water purifier containing the same. Background Technology

[0002] Commercial water purifiers are increasingly being used in various aspects of life, such as airports and high-speed rail stations. The outer shell of current commercial water purifiers is made of sheet metal. The pump inside the water purifier vibrates when it is working, and the vibration and the collision with the sheet metal parts of the machine generate noise. To reduce the noise, buffer materials are usually used to cushion the pump vibration, or sound insulation materials are used to wrap the pump and control the noise inside the sound insulation material. However, the above methods make the cost of water purifiers higher and the noise reduction effect is generally not significant. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology, such as high noise reduction cost and poor noise reduction effect, and to provide a shock absorption device and a pump body and water purifier containing the device.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A shock absorption device, the shock absorption device comprising:

[0006] A first magnet and a second magnet, wherein the first magnet and the second magnet are coaxially arranged and the magnetic poles at corresponding ends of the first magnet and the second magnet are the same, and a foolproof part is provided on the first magnet or the second magnet;

[0007] A support portion is sleeved on the outer periphery of the first magnet and the second magnet, and at least a portion of the first magnet and the second magnet are always located within the support portion.

[0008] In this design, a first magnet and a second magnet are coaxially arranged with identical magnetic poles at their opposite ends. Utilizing the principle of magnetic repulsion, the first and second magnets are kept from contact. By using these non-contact magnets as a vibration damping device, noise is eliminated during operation without contact vibration, thus eliminating noise at its source. Furthermore, the first and second magnets are at least partially always located within the support structure, restricting their position during operation, ensuring the reusability of the vibration damping device, and preventing damping failure caused by the first and second magnets shifting axially. A foolproof design prevents the ends of the first and second magnets that attract each other from facing the end of the second magnet, avoiding repeated installation and improving installation efficiency.

[0009] Preferably, the shock-absorbing device is disposed between the device to be shock-absorbing and the connecting part, and the shock-absorbing device is detachably connected to both the connecting part and the device to be shock-absorbing.

[0010] In this solution, the above-mentioned settings make the installation and disassembly of the shock absorption device more convenient.

[0011] Preferably, threaded holes are provided at the ends of the first magnet away from the second magnet and at the ends of the second magnet away from the first magnet, and the first magnet is connected to the connecting part and the second magnet is connected to the shock-absorbing device by bolt assemblies.

[0012] In this solution, the connecting part, the damping device, and the device to be damped are effectively connected to form a whole by bolt assembly. The damping device is squeezed by the gravity of the device to be damped, so that the damping device limits the first magnet and the second magnet through the connecting part and the device to be damped, ensuring that it is always located within the support part.

[0013] Preferably, the threaded hole in the first magnet does not penetrate the first magnet, while the threaded hole in the second magnet penetrates the second magnet.

[0014] In this solution, the above-mentioned arrangement forms a foolproof structure to prevent the ends of the first magnet and the second magnet from attracting each other from facing the end of the second magnet, thereby improving installation efficiency.

[0015] Preferably, the connecting part and the shock-absorbing device are provided with through holes corresponding to the threaded holes.

[0016] In this solution, the above-mentioned setup allows the bolt assembly to extend into the threaded hole through the through hole, thus avoiding structural interference.

[0017] Preferably, the shock absorption device includes a bracket for connecting to the first magnet, and a connecting part for connecting to the second magnet. Both the bracket and the connecting part are made of metal material that is adsorbed onto the first magnet and the second magnet.

[0018] In this solution, the above-mentioned setup allows for pre-positioning of the metal by means of magnet adsorption before the bolt assembly connects the bracket to the first magnet and the connecting part to the second magnet, thereby reducing installation difficulty.

[0019] Preferably, the bolt assembly is made of a metal material that is adsorbed onto the first magnet and the second magnet.

[0020] In this solution, the above-mentioned settings are used to attract the bolt assembly when it connects the bracket to the first magnet and the connecting part to the second magnet, thereby preventing the bolt assembly from falling off and improving installation efficiency.

[0021] Preferably, the support is made of hard rubber.

[0022] In this solution, the above settings are used to limit the movement of the first magnet and the second magnet, preventing the first magnet and the second magnet from shifting relative to the axis.

[0023] A pump body disposed in a water purifier, the pump body including the shock absorption device as described above.

[0024] In this solution, the pump body is damped by the aforementioned shock absorption device to reduce noise generation, improve the noise reduction effect, reduce noise reduction costs, and enhance the user experience.

[0025] A water purifier comprising a pump body as described above.

[0026] In this solution, the water purifier incorporates the aforementioned shock-absorbing device in the pump body, resulting in lower noise during operation and lower manufacturing and operating costs compared to traditional methods of wrapping the pump body with sound-insulating materials.

[0027] The significant advantages of this invention are as follows: By using a first magnet and a second magnet coaxially arranged with identical magnetic poles at their opposite ends, the first magnet and the second magnet are kept from contact by utilizing the principle of magnetic repulsion. By using these non-contacting magnets as a vibration damping device, noise is eliminated during operation without contact vibration, thus eliminating noise at its source. Furthermore, the first magnet and the second magnet are at least partially always located within the support portion, restricting their position during operation, ensuring the reusability of the vibration damping device, and preventing damping failure caused by the first magnet and the second magnet shifting axially. The inclusion of a foolproof design prevents the ends of the first magnet and the second magnet from attracting each other towards the end of the second magnet, avoiding repeated installation and improving installation efficiency.

[0039] Pump body 30 Detailed Implementation

[0040] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0041] This embodiment provides a shock absorption device, the specific structure of which is as follows: Figure 1 and Figure 2 As shown, the shock absorption device includes: a first magnet 1 and a second magnet 2, the first magnet 1 and the second magnet 2 are coaxially arranged, and the magnetic poles at the corresponding ends of the first magnet 1 and the second magnet 2 are the same, and a foolproof part 3 is provided on the first magnet 1 or the second magnet 2.

[0042] The support part 4 is sleeved on the outer periphery of the first magnet 1 and the second magnet 2, and at least part of the first magnet 1 and the second magnet 2 are always located inside the support part 4.

[0043] Specifically, the first magnet 1 and the second magnet 2 are cylindrical structures, and the support part 4 is a sleeve structure with a circular hole that matches the dimensions of the first magnet 1 and the second magnet 2. The first magnet 1 and the second magnet 2 are magnets used in the prior art to adhere to metal materials. Utilizing the principle of magnetic repulsion, the first magnet 1 and the second magnet 2 are kept from contact within the support part 4. By using the non-contacting first magnet 1 and the second magnet 2 as a vibration damping device, noise is eliminated during operation without contact vibration, thus eliminating noise at its source. Compared to the traditional method of wrapping the vibrating structure with sound-insulating materials, such as sound-insulating cotton, the cost of obtaining magnets is lower, and the absence of contact prevents vibration noise, resulting in a more significant noise reduction effect. Of course, in other embodiments, the first magnet 1, the second magnet 2, and the support part 4 can also have other matching shapes; this is prior art and will not be elaborated upon here.

[0044] Based on this, the first magnet 1 and the second magnet 2 are at least partially always located within the support portion 4. It is understood that when the magnetic poles of the corresponding ends of the first magnet 1 and the second magnet 2 are the same, there is always a gap between the two ends. This gap will vary depending on the magnitude of the force applied to the first magnet 1 by the damping device. However, even when the gap between the corresponding ends of the first magnet 1 and the second magnet 2 increases, they are always located within the support portion 4. This restricts the position of the first magnet 1 and the second magnet 2 during operation through the side wall of the support portion 4, ensuring the reusability of the damping device and avoiding damping failure caused by the first magnet 1 and the second magnet 2 deviating from the axial direction of the support portion 4.

[0045] It should be noted that in this embodiment, the magnetic strength of the magnet is positively correlated with the weight of the shock-absorbing device, that is, the heavier the shock-absorbing device, the stronger the magnetism of the first magnet 1 and the second magnet 2. This is existing technology and will not be elaborated on here.

[0046] In addition, in this embodiment, a foolproof part 3 is provided. The foolproof part 3 is a foolproof structure in the prior art. For example, the first magnet 1 has a protrusion or groove that is not present on the second magnet 2. Similarly, the foolproof part 3 on the second magnet 2 is provided to prevent the ends of the first magnet 1 and the second magnet 2 that attract each other from being installed with the ends of the second magnet 2 facing each other. This avoids the failure of the shock absorption device installation caused by the mutual attraction between the first magnet 1 and the second magnet 2, so that the installer can set the ends of the first magnet 1 and the second magnet 2 in the correct orientation as soon as possible, reducing the installation time required and thereby improving the installation efficiency.

[0047] In this embodiment, the shock-absorbing device is disposed between the device to be shock-absorbing 10 and the connecting part 20, and the shock-absorbing device is detachably connected to the connecting part 20 and the device to be shock-absorbing 10.

[0048] Specifically, the damping device 10 and the connecting part 20 are respectively connected to both ends of the damping device. In this embodiment, the damping device 10 is connected to the end of the first magnet 1 away from the second magnet 2, and the connecting part 20 is connected to the end of the second magnet 2 away from the first magnet 1. In this embodiment, a detachable connection is used to connect the damping device to the damping device 10 and the connecting part 20. Compared with welding, its installation and maintenance are more convenient. It is understood that the detachable connection in this embodiment can be a snap-fit ​​structure connection or a self-locking mechanism connection in the prior art. This is prior art and will not be described in detail here.

[0049] In this embodiment, threaded holes 5 are provided at the ends of the first magnet 1 away from the second magnet 2 and at the ends of the second magnet 2 away from the first magnet 1. The first magnet 1 and the connecting part 20, and the second magnet 2 and the shock-absorbing device 10 are all connected by bolt assemblies.

[0050] Specifically, the bolt assembly is a bolt in the prior art, and the threaded hole 5 is an internal threaded hole opened in the first magnet 1 and the second magnet 2 and used to cooperate with the bolt. The connecting part 20, the damping device and the damping device 10 are effectively connected to form a whole by bolting the bolt assembly. The damping device is squeezed by the gravity of the damping device 10, so that the damping device limits the first magnet 1 and the second magnet 2 through the connecting part 20 and the damping device 10, ensuring that it is always located in the support part 4.

[0051] Meanwhile, in this embodiment, the connecting part 20 and the device to be damped 10 are provided with through holes corresponding to the threaded holes 5. That is, the device to be damped 10 and the connecting part 20 are provided with through holes at the connection points with the first magnet 1 and the second magnet 2, so that the bolt assembly can be inserted into the threaded hole 5 through the through holes to avoid structural interference.

[0052] Furthermore, the threaded hole 5 in the first magnet 1 does not penetrate the first magnet 1, while the threaded hole 5 in the second magnet 2 penetrates the second magnet 2. In this embodiment, the different depths of the threaded holes 5 within the first magnet 1 and the second magnet 2 create a foolproof structure. During installation, the installer can directly determine whether the magnet is the first magnet 1 by visual difference, thereby preventing the ends of the first magnet 1 and the second magnet 2 that attract each other from facing the end of the second magnet 2, thus improving installation efficiency.

[0053] In this embodiment, the shock absorption device 10 includes a bracket 11, which is used to connect with the first magnet 1, and a connecting part 20 is used to connect with the second magnet 2. Both the bracket 11 and the connecting part 20 are made of metal material that is adsorbed onto the first magnet 1 and the second magnet 2.

[0054] Specifically, the connecting part 20 is a flat plate, and the connecting part 20 is made of a metal material that is adsorbed onto the second magnet 2. The bracket 11 has a plate that fits against the first magnet 1, and the plate is also made of a metal material that is adsorbed onto the first magnet 1. This metal material can be iron or nickel, etc., which are existing technologies and will not be described in detail here. By setting the bracket 11 and the connecting part 20 to be made of metal materials that are adsorbed onto the first magnet 1 and the second magnet 2, the installation difficulty is reduced by pre-positioning the metal by adsorbing it onto the magnets before the bolt assembly connects the bracket 11 to the first magnet 1 and the connecting part 20 to the second magnet 2.

[0055] In addition, in this embodiment, the bolt assembly is made of a metal material that is adsorbed onto the first magnet 1 and the second magnet 2. Similarly, the bolt assembly is made of a metal material such as iron or nickel, as is used in the prior art, so that the bolt assembly is adsorbed when the bolt assembly connects the bracket 11 to the first magnet 1 and the connecting part 20 to the second magnet 2, thus preventing the bolt assembly from falling off and improving installation efficiency.

[0056] In this embodiment, the support part 4 is made of hard rubber. This hard rubber is a material in the prior art, which uses its own strength to limit the first magnet 1 and the second magnet 2, preventing the first magnet 1 and the second magnet 2 from shifting relative to the axis.

[0057] This embodiment also provides a pump body 30, which can be a booster pump or a self-priming pump in a water purifier. The pump body 30 is installed in the water purifier and includes the shock-absorbing device as described above. It is understood that the pump body 30 is supported by a bracket 11, which maintains a certain height of the pump body 30 relative to the connecting part 20, preventing water from entering the pump body 30 when the water purifier leaks, thus preventing damage to the pump body 30. The shock-absorbing device is correspondingly installed between the bracket 11 and the connecting part 20 of the pump body 30 to reduce vibration and noise generated by the pump body 30 itself during operation. The first magnet 1 and the second magnet 2 are used for shock absorption and noise reduction to reduce noise generation, improve the noise reduction effect, lower noise reduction costs, and enhance the user experience.

[0058] This embodiment also provides a water purifier that includes the aforementioned pump body 30. The water purifier uses the aforementioned shock-absorbing device to reduce vibration and noise in the pump body 30 during operation, resulting in lower noise levels during use and lower manufacturing and operating costs compared to traditional methods of wrapping the pump body 30 with sound-insulating materials.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
