Abstract
Description
Technical Field
[0001] The present application relates to the technical field of water purification equipment, and in particular to a water hammer buffer and a water purifier. Background Art
[0002] A water purifier, also known as a water purifier or water filter, is a water treatment device that deeply filters and purifies water according to specific usage requirements. A water purifier is typically equipped with a faucet and a solenoid valve. The faucet is used to draw water, while the solenoid valve turns the faucet on and off. When the solenoid valve is momentarily closed, the pressure and kinetic energy of the water flow can cause water hammer, which in turn impacts the pipes and solenoid valve, causing the faucet to shake. This impact can not only damage the pipes and solenoid valve, causing leaks, but the violent shaking of the faucet also seriously affects the user experience. Utility Model Content
[0003] Based on this, it is necessary to provide a water hammer buffer and a water purifier to address the problem that the impact caused by the water hammer phenomenon may damage the pipeline and the solenoid valve and cause water leakage.
[0004] A water hammer buffer, comprising:
[0005] a pipe member having a main channel and a buffer cavity defined therein, wherein the main channel extends longitudinally along a first direction, and the buffer cavity extends longitudinally along a second direction intersecting the first direction and communicating with the main channel;
[0006] a plunger movably mounted in the buffer chamber along the second direction;
[0007] Wherein, the pipe member is further provided with an exhaust hole, and the exhaust hole is located on a side of the plunger away from the main channel.
[0008] With this design, when water flows through the main channel, part of the water will enter the buffer chamber. When the water suddenly changes from a flowing state to a static state, the impact force generated by the water will be transmitted through the water flow and finally act on the plunger, thereby pushing the plunger to move away from the main channel. The movement of the plunger can slow down the impact of the water flow and reduce the impact of the water flow impact on the faucet or other components.
[0009] In one embodiment, the water hammer buffer further includes an elastic member, wherein the elastic member is deformably disposed between the plunger and the top wall of the buffer cavity along the second direction;
[0010] When the plunger moves in a direction away from the main channel, the elastic member accumulates elastic force for causing the plunger to move toward the main channel.
[0011] With such a design, when the impact force generated by the water flow pushes the plunger to move in a direction away from the main pipe, the impact force needs to overcome the elastic force of the elastic member, so that the impact force can be effectively buffered.
[0012] In one embodiment, the elastic member is a spring, and a first mounting post is formed on the top wall of the buffer cavity in the second direction, and one end of the spring is sleeved on the first mounting post;
[0013] And / or, a second mounting post is provided on the plunger, and the other end of the spring is sleeved on the second mounting post.
[0014] With such a design, one end of the spring is sleeved on the first mounting post, and the other end of the spring is sleeved on the second mounting post, thereby achieving fixation of the spring.
[0015] In one embodiment, the circumferential side wall of the plunger is in contact with the side wall of the buffer cavity.
[0016] This design enables the plunger to stably move along the second direction Y under the action of the side wall of the buffer cavity. At the same time, the fit between the plunger and the side wall of the buffer cavity prevents water from flowing to the side of the plunger away from the buffer cavity, thereby reducing the problem of water leakage from the vent.
[0017] In one embodiment, a sealing groove is provided on the circumferential side wall of the plunger, and a sealing ring is provided in the sealing groove. The sealing ring is used to seal the gap between the plunger and the side wall of the buffer cavity.
[0018] With this design, the sealing ring further prevents water from flowing into the side of the plunger away from the buffer chamber, thereby reducing the problem of water leakage from the exhaust hole.
[0019] In one embodiment, the pipeline member includes a pipeline body and a pressure cover, the pipeline body is provided with the main channel, the pressure cover is detachably provided on the pipeline body, and is surrounded by the pipeline body to form the buffer cavity, and the pressure cover is provided with the exhaust hole.
[0020] With this design, when installing the elastic part and the plunger, the pressure cover can be removed from the pipe body first, thereby opening the buffer cavity, so that the plunger and the elastic part can be installed into the buffer cavity, and then the pressure cover can be installed on the pipe body to seal the buffer cavity and complete the installation of the plunger and the elastic part.
[0021] In one embodiment, the gland is provided with an internal thread, the pipe body is provided with an external thread, and the gland is threadably connected to the pipe body.
[0022] With this design, the threaded connection method can effectively improve the assembly efficiency of the gland and the pipe body.
[0023] In one embodiment, the water hammer damper further includes a joint, which is provided at at least one end of the pipe member in the first direction, and the joint is connected to the main channel.
[0024] With this design, the water hammer buffer can be quickly assembled with the faucet or water purification device by connecting it to the joint, thereby improving the assembly efficiency of the water purifier.
[0025] In one embodiment, the pipeline further includes a bypass channel, which extends longitudinally along the second direction and connects the main channel and the buffer chamber. The cross-sectional area of the bypass channel is smaller than the cross-sectional area of the plunger.
[0026] This design prevents the plunger from entering the bypass channel, thus preventing the plunger from entering the main channel and blocking the water flow in the main channel.
[0027] A water purifier comprises a water purification device, a faucet and a water hammer buffer as described in any one of the above items, wherein the water hammer buffer is connected to the water purification device and the faucet.
[0028] In the above-mentioned water hammer buffer, when water flows through the main channel, part of the water flow will enter the buffer chamber. When the water flow suddenly changes from a flowing state to a static state, the impact force generated by the water flow will be transmitted through the water flow and finally act on the plunger, thereby pushing the plunger to move in a direction away from the main channel. The movement of the plunger can slow down the impact of the water flow and reduce the impact of the water flow impact on the faucet or other components. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] See Figure 1 and Figure 2 , Figure 1 The structure of a water hammer damper according to an embodiment of the present application is shown. The water hammer damper provided in this embodiment of the present application includes a pipe member 10 and a plunger 20. The pipe member 10 is used to connect the faucet and the water purification device, so that the purified water filtered by the water purification device is input into the faucet through the pipe member 10. Specifically, the pipe member 10 has a main channel 11 formed therein. The main channel 11 connects the water outlet of the water purification device and the water inlet of the faucet. The purified water generated by the water purification device enters the faucet through the main channel 11 and is finally output through the faucet for consumption by the user.
[0043] During actual use, the faucet will switch between open and closed according to the user's needs. When the faucet is opened, water flows into the faucet from the main channel 11 and flows out of the faucet. When the faucet is suddenly closed, the water flow suddenly changes from a flowing state to a stationary state, and the impact force generated may affect the normal operation of the faucet or other components.
[0044] To this end, the pipe member 10 is further provided with a buffer chamber 12 and an exhaust hole 13. The buffer chamber 12 is communicated with the main channel 11, and the exhaust hole 13 is communicated with the buffer chamber 12. The water hammer buffer further comprises a plunger 20, which is movably mounted in the buffer chamber 12 along the second direction Y. The exhaust hole 13 is located on the side of the plunger 20 away from the main channel 11, and the exhaust hole 13 communicated with the buffer chamber 12 allows the air in the buffer chamber 12 to circulate smoothly with the outside, thereby ensuring the normal movement of the plunger 20 in the buffer chamber 12.
[0045] In this way, when water flows through the main channel 11, part of the water will enter the buffer chamber 12. When the water suddenly changes from a flowing state to a static state, the impact force generated by the water will be transmitted through the water and finally act on the plunger 20, thereby pushing the plunger 20 to move in a direction away from the main channel 11. The movement of the plunger 20 can slow down the impact of the water flow and reduce the impact of the water flow impact on the faucet or other components.
[0046] Specific to Figure 1 In the embodiment, the first direction X is the left-right direction, and the second direction Y is the up-down direction. When the impact force generated by the sudden stop of the water flow acts on the plunger 20, the plunger 20 will move upward. The impact force is buffered by pushing the plunger 20 upward, thereby reducing the impact of the water flow impact force on the faucet or other components.
[0047] In some embodiments of the present application, in order to improve the buffering effect of the impact force of water flow, the water hammer buffer also includes an elastic member 21, which is deformably arranged between the plunger 20 and the top wall of the buffer chamber 12 along the second direction Y, and when the plunger 20 moves in a direction away from the main channel 11, the elastic member 21 accumulates an elastic force for causing the plunger 20 to move toward the main channel 11.
[0048] In this way, when the impact force generated by the water flow pushes the plunger 20 to move away from the main pipe, the impact force needs to overcome the elastic force of the elastic member 21, so that the impact force can be effectively buffered. Figure 1 In the embodiment, the elastic member 21 is provided on the side of the plunger 20 away from the main channel 11. When the plunger 20 moves upward under the impact force generated by the water flow, the elastic member 21 will be compressed. Figure 2 As shown, the impact of the water flow is effectively buffered by the gravity of the plunger 20 and the elastic force of the elastic member 21.
[0049] When the water flow becomes still, the elastic force stored in the elastic member 21 is released, thereby pushing the plunger 20 toward the main channel 11, thereby resetting the plunger 20 so that the plunger 20 can buffer the impact force generated by the next water flow.
[0050] Optionally, the elastic member 21 is a spring 22. In other embodiments, the elastic member 21 can also be made of an elastic material such as rubber. Furthermore, to facilitate the installation of the spring 22, a first mounting post 14 is defined on the top wall of the buffer chamber 12 in the second direction Y, and a second mounting post 23 is defined on the plunger 20. Both the first mounting post 14 and the second mounting post 23 are located within the buffer chamber 12 and extend longitudinally in the second direction Y. One end of the spring 22 is sleeved onto the first mounting post 14, and the other end of the spring 22 is sleeved onto the second mounting post 23, thereby securing the spring 22.
[0051] In some other embodiments, the spring 22 may also be installed on the pipe member 10 by welding, bonding, etc., which is not limited here.
[0052] In some embodiments of the present application, the circumferential sidewalls of the plunger 20 fit closely with the sidewalls of the buffer chamber 12, so that the sidewalls of the buffer chamber 12 can guide the movement of the plunger 20. This allows the plunger 20 to stably move along the second direction Y under the action of the sidewalls of the buffer chamber 12. Furthermore, the fit between the plunger 20 and the sidewalls of the buffer chamber 12 prevents water from flowing to the side of the plunger 20 away from the buffer chamber 12, thereby reducing the risk of water leaking from the vent 13.
[0053] Furthermore, a sealing groove 24 is provided on the circumferential side wall of the plunger 20, and a sealing ring 25 is provided in the sealing groove 24. The sealing ring 25 is used to seal the gap between the plunger 20 and the side wall of the buffer chamber 12, thereby further preventing water from flowing into the side of the plunger 20 away from the buffer chamber 12 through the sealing ring 25, reducing the problem of water leakage from the exhaust hole 13.
[0054] In some embodiments of the present application, the pipe member 10 includes a pipe body 15 and a gland 16. The pipe body 15 is provided with a main channel 11. The gland 16 is detachably mounted on the pipe body 15 and, together with the pipe body 15, forms a buffer chamber 12. The gland 16 is provided with a vent 13. Separating the pipe member 10 into the pipe body 15 and the gland 16 effectively improves the assembly efficiency of the water hammer damper.
[0055] Specifically, when installing the elastic member 21 and the plunger 20, the pressure cap 16 can be removed from the pipe body 15 first, thereby opening the buffer cavity 12, so that the plunger 20 and the elastic member 21 can be installed into the buffer cavity 12, and then the pressure cap 16 can be installed on the pipe body 15 to seal the buffer cavity 12 and complete the installation of the plunger 20 and the elastic member 21.
[0056] In some embodiments, the gland 16 is provided with an internal thread 17, and the pipe body 15 is provided with an external thread 18. The external thread 18 and the internal thread 17 cooperate with each other to enable the gland 16 to be threadedly connected to the pipe body 15. This threaded connection can effectively improve the assembly efficiency of the gland 16 and the pipe body 15. In other embodiments, the gland 16 and the pipe body 15 can also be fixed to each other by welding, snap-fitting, or other methods, which are not limited here.
[0057] In some embodiments of the present application, the pipe member 10 further includes a bypass channel 31, which extends longitudinally along the second direction Y and connects the main channel 11 and the buffer chamber 12. The cross-sectional area of the bypass channel 31 is smaller than the cross-sectional area of the plunger 20, that is, the size of the plunger 20 is larger than the size of the bypass channel 31, so that the plunger 20 does not enter the bypass channel 31, thereby preventing the plunger 20 from entering the main channel 11 and blocking the water flow in the main channel 11. It should be noted that the cross-sectional area refers to the projected area of the bypass channel or the plunger 20 on a plane perpendicular to the second direction Y.
[0058] An embodiment of the present application also provides a water purifier, including a water purification device, a faucet and a water hammer buffer as in any of the above embodiments. The main channel 11 connects the water outlet of the water purification device and the water inlet of the faucet. The pure water generated by the water purification device enters the faucet through the main channel 11 and is finally output through the faucet.
[0059] Among them, the opening and closing of the faucet can be controlled by a solenoid valve or a switch valve, and a water hammer buffer is provided between the water purification device and the faucet, so that when the faucet is opened and closed, the impact force generated by the water flow will be transmitted through the water flow, and finally act on the plunger 20, thereby pushing the plunger 20 to move in a direction away from the main channel 11, and the movement of the plunger 20 can slow down the impact of the water flow, reduce the impact of the water flow impact force on the faucet or other components, and reduce the shaking of the faucet.
[0060] In some embodiments of the present application, to facilitate connection between a faucet or water purifier and the water hammer damper, the water hammer damper further includes a connector 30. The connector 30 is disposed at at least one end of the pipe member 10 in the first direction X, and the connector 30 is in communication with the main channel 11. By connecting the connector 30 to the faucet or water purifier, the water hammer damper can be quickly assembled with the faucet or water purifier, thereby improving the assembly efficiency of the water purifier.
[0061] The above-mentioned water hammer buffer has at least the following advantages:
[0062] When water flows through the main channel 11, part of the water will enter the buffer chamber 12. When the water suddenly changes from a flowing state to a static state, the impact force generated by the water will be transmitted through the water and finally act on the plunger 20, thereby pushing the plunger 20 to move away from the main channel 11. The movement of the plunger 20 slows down the impact of the water flow and reduces the impact of the water flow impact on the faucet or other components.
[0063] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0064] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
