Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field of water purifiers, and particularly to a water purification device and its water pressure buffering structure. Background Art

[0002] A water purifier is a device used to filter and purify water quality. In some areas, especially in high-rise buildings or places far from the water source, the water pressure may be insufficient. In this case, the water purifier may not work properly because it requires a certain water pressure to push water through the filtering medium. Or for some types of water purifiers, such as reverse osmosis systems, a certain water flow rate is required to ensure the filtering effect.

[0003] Therefore, water purifiers often need to be equipped with a water pump to provide additional pressure. However, the water pressure of the water pumped out by the water pump after pressurization is too high, causing relatively strong water vibration, which will cause certain damage to the water outlet interface, and at the same time resulting in relatively loud noise of the water purifier, bringing a strong sense of discomfort to users. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the present utility model provides a water purification device and its water pressure buffering structure, which can relieve the water flow pressure pumped out by the water pump.

[0008] As one of the embodiments, the housing includes a first limiting portion and a second limiting portion. The first limiting portion is connected to the side of the water inlet hole facing the buffer member, and the second limiting portion is connected to the side of the water outlet hole facing the buffer member.

[0009] As one of the embodiments, the first limiting portions are uniformly spaced along the circumferential direction of the water inlet hole; the second limiting portions are uniformly spaced along the circumferential direction of the water outlet hole.

[0010] As one of the embodiments, the material of the buffer member is an elastic material.

[0011] As one of the embodiments, along the radial direction of the pipeline, the buffer member is provided with a plurality of through holes.

[0029] In order to make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] The embodiments of the present application provide a water purification device. The water purification device includes a water pump and a water pressure buffering structure. The water pump is connected to the water pressure buffering structure. The water pump pressurizes the water and pumps it to the water pressure buffering structure. The water pressure buffering structure buffers the water to relieve the pressure of the water flow, and then guides the water flow to the water outlet structure. The water pressure received by the water outlet structure is relatively small, which can avoid vibration and reduce the noise during the use of the water purification device.

[0031] It should be noted that the water outlet structure can be a device such as a water outlet faucet.

[0032] Refer to Figure 1 , for the convenience of description, Figure 1 in [[reference]], X represents the axial direction X and Y represents the radial direction Y; the above water pressure mitigation structure includes a housing 10 and a buffer member 20. An installation cavity 105 is formed inside the housing 10. The housing 10 has a water inlet 101 and a water outlet 102. The installation cavity 105 is respectively communicated with the water inlet 101 and the water outlet 102; the buffer member 20 is movably arranged in the installation cavity 105, and the buffer member 20 is used for buffering water pressure; wherein, along the axial direction X of the housing 10, the buffer member 20 is relatively spaced from the housing 10, and along the radial direction Y of the housing 10, the buffer member 20 is relatively spaced from the housing 10.

[0033] In practical applications, the water inlet 101 is connected to a water pump. The water pump pressurizes the water and guides it to the water inlet 101. The pressurized water flow enters the installation cavity 105 from the water inlet 101. The buffer member 20 is movably arranged in the installation cavity 105, and along the axial direction X and the radial direction Y, the buffer member 20 is spaced from the installation cavity 105. Thus, under the impact of the water flow, the buffer member 20 can move in the installation cavity 105. The buffer member 20 plays a role in obstructing the water flow, which can effectively reduce the initial impact force of the water flow. The water flow can only pass through the outer surface of the buffer member 20, extending the path of the water flow, thereby further reducing the pressure of the water flow and avoiding vibration at the connection of the water outlet structure.

[0034] Compared with the prior art, the spaced arrangement of the buffer member 20 and the housing 10 in this application provides a space for the buffer member 20 to move. When the water flow enters the installation cavity 105, the buffer member 20 plays a role in obstructing the water flow to relieve the water flow with too high a flow rate and reduce the water pressure and impact force of the water flow. The water purification device adopting this device can reduce the noise generated during operation, reduce the vibration caused by water pressure, and maintain the stability of the connection of the water outlet structure.

[0035] Refer to again Figure 1 , in one embodiment, the installation cavity 105 has a water inlet hole 1051 and a water outlet hole 1052. The water inlet hole 1051 is connected to the water inlet 101, and the water outlet hole 1052 is connected to the water outlet 102. The buffer member 20 is arranged between the water inlet hole 1051 and the water outlet hole 1052. Among them, the cross-sectional area of the buffer member 20 is larger than the cross-sectional area of the water outlet hole 1052, and the cross-sectional area of the buffer member 20 is larger than the cross-sectional area of the water inlet hole 1051.

[0036] To prevent the water flow from flushing the buffer member 20 out of the installation cavity 105, the cross-sectional area of the buffer member 20 is set to be larger than the cross-sectional areas of the water inlet hole 1051 and the water outlet hole 1052, which can effectively prevent the buffer member 20 from being washed away from the installation cavity 105 and improve the practicality of the device.

[0037] Refer to again Figure 1 Figure 1 , in one embodiment, the housing 10 includes a first limiting portion 106 and a second limiting portion 107. A first limiting portion 106 is connected to the side of the water inlet hole 1051 facing the buffer member 20, and a second limiting portion 107 is connected to the side of the water outlet hole 1052 facing the buffer member 20. The first limiting portion 106 is used to abut against the buffer member 20 to space the buffer member 20 and the water inlet hole 1051, and the second limiting portion 107 is used to abut against the buffer member 20 to space the buffer member 20 and the water outlet hole 1052.

[0038] In practical applications, since the cross-sectional area of the buffer member 20 is larger than the cross-sectional areas of the water inlet hole 1051 and the water outlet hole 1052, when the water flow is flowing, it is possible to wash the buffer member 20 towards the water outlet hole 1052, resulting in the buffer member 20 blocking the water outlet hole 1052 and affecting the normal flow of the water flow. Therefore, the first limiting portion 106 and the second limiting portion 107 are provided in this device. Through the limiting action of the first limiting portion 106 and the second limiting portion 107, the buffer member 20 is prevented from contacting the water outlet hole 1052 or the water inlet hole 1051, avoiding the buffer member 20 blocking the water outlet hole 1052 or the water inlet hole 10�1, and protecting the normal water outlet function of the water purification device.

[0039] Refer to Figure 2 and Figure 3 Figure 3 , in one embodiment, the first limiting portion 106 is uniformly spaced along the circumferential direction of the water inlet hole 1051; the second limiting portion 107 is uniformly spaced along the circumferential direction of the water outlet hole 1052. Due to the irregular movement of the buffer member 20 in the installation cavity 105, the first limiting portion 106 and the second limiting portion 107 are uniformly spaced, which can prevent the buffer member 20 from approaching the water inlet hole 1051 or the water outlet hole 1052 from multiple directions, further preventing the buffer member 20 from blocking the water inlet hole 1051 or the water outlet hole 1052. At the same time, the first limiting portion 106 and the second limiting portion 107 are spaced apart to leave a channel for the water flow to flow, ensuring the normal water outlet function of the water purification device.

[0040] In one embodiment, the material of the buffer member 20 can be an elastic material. In practical applications, the buffer member 20 moves in the installation cavity 105 under the impact of the water flow. Inevitably, the buffer member 20 will collide with the housing 10. If the elastic material buffer member 20 collides with the housing 10, through its own elastic deformation, it can avoid collision damage to itself and the housing 10, and can further relieve the water pressure.

[0041] Refer to Figure 4, in one embodiment, the number of the buffer members 20 can be one or more, and the shapes of the multiple buffer members 20 can be the same or different. When there are multiple buffer members 20, the multiple buffer members 20 can adopt the same shape, which is more convenient for production, or can adopt different shapes, so as to obstruct the water flow from multiple angles and reduce the water pressure of the water flow.

[0042] Referring to Figure 5 , in one embodiment, the buffer member 20 is provided with a plurality of through holes 201. The through holes 201 can reduce the thickness of the buffer member 20, making the buffer member 20 more prone to deformation, which is beneficial to reducing the water pressure; at the same time, the through holes 201 can allow the water flow to pass through. Since the buffer member 20 plays a certain role in obstructing the water flow, it has a certain impact on the water outlet efficiency to a certain extent. By providing the through holes 201, the efficiency of the water flow passing through can be improved, the impact of the buffer member 20 on the water outlet efficiency can be reduced, and the water outlet efficiency during the normal use of the water purification device can be ensured.

[0043] In one embodiment, referring to Figure 5 and Figure 6 , the buffer member 20 can be spherical or ellipsoidal or prismatic. Preferably, the buffer member 20 is spherical, which is easy to move in the installation cavity 105. At the same time, the circular outer surface can reduce the collision force generated by the collision with the housing 10, playing a role in protecting the housing 10.

[0044] It can be understood that the shape of the buffer member 20 is not limited to the above-mentioned spherical, ellipsoidal and prismatic shapes. In some other embodiments, buffer members 20 with other shapes can also be adopted.

[0045] Referring again to Figure 2 and Figure 3 , the housing 10 includes an inlet pipe 103 and an outlet pipe 104. The inlet pipe 103 has an inlet 101 and a first cavity 1031 communicating with the inlet 101. The outlet pipe 104 has an outlet 102 and a second cavity 1041 communicating with the outlet 102. The inlet pipe 103 and the outlet pipe 104 are connected so that the first cavity 1031 and the second cavity 1041 communicate to form an installation cavity 105.

[0046] In practical applications, in order to facilitate the placement of the buffer member 20, the housing 10 includes an inlet pipe 103 and an outlet pipe 104. First, the buffer member 20 is placed into the first cavity 1031 or the second cavity 1041, and then the inlet pipe 103 and the outlet pipe 104 are connected together. Specifically, the inlet pipe 103 and the outlet pipe 104 can be fixedly connected, such as by welding, to improve the sealing performance of the device and prevent water leakage; or the inlet pipe 103 and the outlet pipe 104 can be detachably connected, such as by threaded connection. This setting facilitates the replacement of the buffer member 20 and improves the service life of the device.

[0047] Different from the prior art, the embodiment of the present application provides a water purification device and a water pressure buffering structure thereof. The water pressure buffering structure includes a housing 10 and a buffer member 20. An installation cavity 105 is formed inside the housing 10. The housing 10 has a water inlet 101 and a water outlet 102. The installation cavity 105 is respectively communicated with the water inlet 101 and the water outlet 102. The buffer member 20 is movably arranged in the installation cavity 105 and is used for buffering the water pressure. Wherein, along the axial direction X of the housing 10, the buffer member 20 is spaced apart from the housing 10 relatively, and along the radial direction Y of the housing 10, the buffer member 20 is spaced apart from the housing 10 relatively. Compared with the prior art, the spaced arrangement of the buffer member 20 and the housing 10 in the present application provides a space for the buffer member 20 to move. When water flow enters the installation cavity 105, the buffer member 20 plays a role in obstructing the water flow, so as to relieve the water flow with too high a flow rate and reduce the water pressure and impact force of the water flow. The water purification device adopting this device can reduce the noise generated during operation, reduce the vibration caused by the water pressure, and maintain the stability of the connection at the water outlet structure.

[0048] The above are only the specific embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
