DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0027] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0028] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0029] See also Figure 1 and Figure 2As shown, according to an embodiment of the present invention, a buffer is provided, which includes a shell 1 and a buffer member 2; a first inlet and outlet 101 and a second inlet and outlet 102 are respectively provided at both ends of the shell 1, and along the axial direction of the shell 1, the shell 1 has a main channel 11 and a bypass chamber 12, and the two ends of the main channel 11 are respectively connected with the first inlet and outlet 101 and the second inlet and outlet 102, and the bypass chamber 12 has a first port 121 and a second port 122, the first port 121 is sealed with the first inlet and outlet 101, and the second port 122 is connected with the second inlet and outlet 102; the buffer member 2 is arranged in the bypass chamber 12, the first end of the buffer member 2 is connected with the first port 121, and the second end of the buffer member 2 is telescopically arranged relative to the second port 122.

[0030] Specifically, the buffer is set on the pipeline, and the water in the pipeline flows into the shell 1 from the second inlet and outlet 102. When the water flows to the second inlet and outlet 102, the water flow will be diverted, and most of the water flow will flow into the main channel 11. Since the bypass chamber 12 is also connected to the second inlet and outlet 102, a small amount of water flow will flow into the bypass chamber 12. The water flow flowing into the bypass chamber 12 will squeeze the buffer 2, and the length of the buffer 2 will be shortened. After the buffer 2 is shortened to the limit length, the buffer 2 will no longer shorten; when the water flow pressure in the pipeline decreases or there is no water flow, the water flow pressure decreases, and the length of the buffer 2 will extend. If there is water remaining in the bypass chamber 12, the buffer 2 can also discharge the water from the bypass chamber 12 until the second end of the buffer 2 abuts against the second port 122 of the shell 1, and the buffer 2 no longer extends.

[0031] In this embodiment, the retractable nature of the buffer 2 absorbs the impact force generated by water hammer, reducing its direct impact on the pipelines and solenoid valves. When water flow suddenly stops or pressure suddenly changes, the buffer 2's retractable motion mitigates the rapid change in water pressure, thereby reducing the impact on the system. This helps protect the pipelines, solenoid valves, and other system components, extending their service life. When water pressure decreases or ceases, the buffer 2 drains residual water from the bypass chamber 12, keeping the system dry and clean. Once water pressure returns, the buffer 2 automatically resets, preparing for the next water flow buffering operation without requiring human intervention. Through flow diversion and the retractable nature of the buffer 2, the buffer effectively absorbs and reduces the impact force generated by water hammer, thereby protecting the pipelines and solenoid valves from damage. Furthermore, because the buffer absorbs the kinetic energy of the water flow, it reduces the impact of the water flow on the pipelines and solenoid valves, extending their service life and reducing maintenance and replacement costs.

[0032] In addition, by absorbing and mitigating impact force, the combination of the buffer 2 and the bypass chamber 12 helps protect system components such as pipelines and solenoid valves, extending their service life. Moreover, placing the buffer 2 in the bypass chamber 12 does not affect the flow of water in the main channel 11.

[0033] It is worth noting that in this embodiment, although the water flows from the second inlet and outlet 102 to the first inlet and outlet 101, when the water flows from the first inlet and outlet 101 to the second inlet and outlet 102, when the water flows to the second inlet and outlet 102, the water in the main channel 11 will still flow into the bypass chamber 12.

[0034] See also Figures 1 to 4 As shown, the second end of the buffer 2 separates the bypass chamber 12 into a first chamber 123 and a second chamber 124 that are isolated from each other. The first end of the buffer 2 is located in the first chamber 123, and the second chamber 124 is connected to the second inlet and outlet 102. The second end of the buffer 2 can be telescopically set so that the volume of the second chamber 124 can be adjusted.

[0035] Specifically, since the buffer 2 is retractable, that is, it is subject to the impact force of water, the length of the buffer 2 will change. When the water first flows into the second chamber 124, the water squeezes the buffer 2, and the length of the buffer 2 is shortened. After the buffer 2 is shortened to the limit length, the buffer 2 no longer shortens. At this time, the volume of the second chamber 124 is greater than the volume of the first chamber 123, and the water only exists in the second chamber 124; when the water pressure in the pipeline decreases or there is no water flow, the water pressure decreases, and the length of the buffer 2 is extended. As the length of the buffer 2 gradually extends, the volume of the first chamber 123 gradually increases, while the volume of the second chamber 124 gradually decreases, and as the volume of the second chamber 124 gradually decreases, the water is discharged from the second chamber 124.

[0036] In this embodiment, because the length of the buffer 2 changes according to water pressure, the increased volume of the second chamber 124 also means that more water can flow into the second chamber 124. The retractability of the buffer 2 allows the volume of the second chamber 124 to change dynamically, automatically adjusting to the impact force and pressure changes of the water flow to adapt to different water flow conditions. When the water flow pressure is high, the buffer 2 is compressed, absorbing the kinetic energy of the water flow; when the water flow pressure decreases, the buffer 2 expands and recovers, thereby reducing the impact of sudden changes in water flow on the system. Furthermore, the expansion and contraction of the buffer 2 reduces the water hammer effect caused by sudden stops or changes in water flow, protecting pipes and equipment from damage. When the water flow pressure changes, the expansion and contraction of the buffer 2 stabilizes the water flow, reduces water fluctuations, and provides a smoother water output. When the water flow stops, the expansion of the buffer 2 helps drain the residual water in the second chamber 124, reducing water accumulation and potential bacterial growth.

[0037] See also Figures 1 to 4 As shown, the buffer member 2 includes an elastic member 201 and a sealing member 202, one end of the elastic member 201 is connected to the first port 121, and the other end of the elastic member 201 is connected to the sealing member 202, and the sealing member 202 is movably arranged along the axial direction of the bypass chamber 12, and the sealing member 202 separates the bypass chamber 12 into a first chamber 123 and a second chamber 124.

[0038] Specifically, when water flows into the second chamber 124 first, the water will contact the sealing member 202, and the sealing member 202 will be displaced by the impact of the water flow. The sealing member 202 squeezes the length of the elastic member 201 to shorten until the elastic member 201 shortens to the limit length, and the elastic member 201 no longer shortens. At this time, the volume of the second chamber 124 is greater than the volume in the first chamber 123. Due to the provision of the sealing member 202, the water only exists in the second chamber 124; when the water pressure in the pipeline decreases or there is no water flow, the water pressure decreases, the pressure on the side of the sealing member 202 disappears, the elasticity of the elastic member 201 is restored, the length of the elastic member 201 is extended, and the elastic member 201 pushes the sealing member 202 to move. As the length of the elastic member 201 gradually extends, the volume of the first chamber 123 gradually increases, while the volume of the second chamber 124 gradually decreases, and as the volume of the second chamber 124 gradually decreases, the water is discharged from the second chamber 124.

[0039] In this embodiment, the volumes of the first chamber 123 and the second chamber 124 are dynamically adjusted by the expansion and contraction of the elastic member 201 to adapt to different water pressures and flow rates. The seal 202 separates the bypass chamber 12 into two independent chambers to ensure that the water flows only in the second chamber 124, prevents water backflow, and ensures the control of the water flow direction. The coordinated work of the elastic member 201 and the seal 202 reduces the water hammer effect and protects the pipeline and the solenoid valve from damage. The rapid expansion and contraction response of the elastic member 201 can improve the system's response speed to water flow changes, making the system more sensitive and efficient.

[0040] As a specific embodiment, the outer peripheral side of the seal 202 is in full contact with the inner wall of the bypass chamber 12, and in the process of the elastic member 201 driving the seal 202 to move, it can still ensure that water will not flow from the second chamber 124 to the first chamber 123.

[0041] See also Figures 1 to 4 As shown, the buffer member 2 further includes a water stopper 203 , and the end of the elastic member 201 close to the second port 122 , the water stopper 203 and the sealing member 202 are connected in sequence.

[0042] In this embodiment, water retaining member 203 is located between elastic member 201 and sealing member 202. Working together, water retaining member 203 and sealing member 202 can more effectively prevent water from flowing between the two chambers, improving sealing performance and preventing water leakage. The presence of water retaining member 203 provides additional resistance to water impact, working in conjunction with elastic member 201 to enhance the buffering effect and reduce the impact of water hammer on the system. Water retaining member 203 protects elastic member 201 from direct impact from the water flow, thereby extending the service life of elastic member 201.

[0043] As a specific implementation method, the elastic part 201 is a spring, the sealing part 202 is a sealing ring, and the water retaining part 203 is a water retaining ring. The stiffness of the elastic part 201 is selected according to the pressure of the water flow in the corresponding pipeline. If the water flow pressure is very large and the water hammer phenomenon is more obvious, the stiffness of the elastic part 201 is large. In any case, the water flow pressure is small and the water hammer phenomenon is not very obvious. At this time, the stiffness of the elastic part 201 needs to be small, so that even if the water flow pressure is small, the elastic part 201 can still expand and contract.

[0044] See also Figure 1 and Figure 2 As shown, as another embodiment of this embodiment, the buffer component 2 includes an air tube and an airbag (not shown in the figure), one end of the air tube is connected to the first port 121, and the other end of the air tube is connected to the airbag, and the airbag is deformably arranged along the axial direction of the bypass chamber 12, and the airbag separates the bypass chamber 12 into a first chamber 123 and a second chamber 124.

[0045] Specifically, when the water flows into the second chamber 124 first, the water will contact the airbag, and the airbag will be displaced by the impact of the water. The airbag will be deformed by the impact force, and the airbag will deform toward the first chamber 123. The overall length of the airbag will be shortened until the airbag is no longer deformed. At this time, the volume of the second chamber 124 is greater than the volume of the first chamber 123. Since the airbag is deformed, the outer wall of the airbag is fully in contact with the inner wall of the bypass chamber 12, and the water flow only exists in the second chamber 124; when the water flow pressure in the pipeline decreases or there is no water flow, the water flow pressure decreases, the shape of the airbag is restored, the volume of the first chamber 123 gradually increases, and the volume of the second chamber 124 gradually decreases, and as the volume of the second chamber 124 gradually decreases, the water flow is discharged from the second chamber 124.

[0046] In this embodiment, the airbag deforms when impacted by water flow, absorbing the kinetic energy of the water flow, reducing direct impact on the system and protecting pipes and equipment. The airbag's deformability enables it to dynamically adjust the volume of the first chamber 123 and the second chamber 124 to accommodate varying water flow pressures and flow rates. This deformation reduces the water hammer effect caused by sudden stops or changes in the water flow. Due to its softness and deformability, the airbag provides enhanced cushioning, particularly in absorbing shock and vibration. The airbag can automatically adjust its volume based on pressure changes, adapting to varying operating conditions and providing dynamic cushioning and sealing. The airbag is typically made of rubber and has excellent sealing properties, effectively preventing water or gas leakage. Due to its material properties, the airbag is typically more durable than the elastic member 201 and the seal 202. Especially in environments with high pressure and repeated pressure fluctuations, the airbag can automatically adjust its shape based on changes in internal pressure, maintaining an effective seal and cushioning effect under varying operating pressures.

[0047] As a specific embodiment, the air pipe extends out of the shell 1 and is connected to an external air supply device. The airbag is deformed by deflating or inflating the airbag. In the absence of an air supply device, the elastic deformation of the airbag itself is utilized.

[0048] See also Figures 1 to 4 As shown, a communicating hole 103 is opened on the wall of the shell 1 , one end of the communicating hole 103 is communicated with the first chamber 123 , and the other end of the communicating hole 103 passes through the wall of the shell 1 .

[0049] In this embodiment, to ensure that the seal 202 is shortened or the airbag is deformed, the gas in the first chamber 123 is discharged through the connecting hole 103, thereby preventing excessive pressure in the first chamber 123 and preventing the seal 202 or the airbag from malfunctioning. The connecting hole 103 allows the gas in the first chamber 123 to be discharged to balance the pressure between the first chamber 123 and the external environment, preventing the seal 202 or the airbag from malfunctioning due to pressure accumulation. The discharge of gas through the connecting hole 103 prevents excessive pressure in the first chamber 123, thereby protecting the seal 202 or the airbag from damage due to excessive pressure. In addition, the presence of the connecting hole 103 allows the gas to be discharged quickly, improving the response speed of the seal 202 or the airbag to pressure changes. For the airbag, the connecting hole 103 can prevent the airbag from rupturing due to excessive internal pressure.

[0050] See also Figures 1 to 5As shown, the shell 1 includes a first tube body 3 and a second tube body 4. The first tube body 3 is located radially inside the second tube body 4. The first tube body 3 has a main channel 11. A bypass chamber 12 is formed between the outer wall of the first tube body 3 and the inner wall of the second tube body 4. The first tube body 3 has a first inlet and outlet 101, and the second tube body 4 has a second inlet and outlet 102. The first inlet and outlet 101 and the second inlet and outlet 102 are relatively arranged. The buffer member 2 is sleeved on the first tube body 3, and the first end of the buffer member 2 is connected to the outer wall of the first tube body 3 or to the inner wall of the second tube body 4.

[0051] Specifically, most of the water flows out from the first tube body 3, and a small amount of water flows between the outer wall of the first tube body 3 and the inner wall of the second tube body 4. By placing the first tube body 3 on the radial inner side of the second tube body 4, a more compact system structure can be designed, and a bypass chamber 12 can be formed to improve the integration of the overall design. The bypass chamber 12 between the first tube body 3 and the second tube body 4 can serve as a pressure balance space, which helps to maintain the pressure stability inside the system and reduce system damage caused by pressure fluctuations. The first tube body 3 has a main flow channel 11, and the bypass chamber 12 between the first tube body 3 and the second tube body 4 can serve as a bypass channel. This design can effectively distribute fluid, optimize fluid dynamics, and improve fluid flow efficiency. The buffer 2 is mounted on the first tube body 3, and its first end is connected to the inner wall of the first tube body 3 or the second tube body 4. This arrangement can provide better buffering performance, absorb the impact force of the water flow, reduce the water hammer effect, and protect the system from damage. In addition, the relatively arranged inlets and outlets of the first tube body 3 and the second tube body 4 and the arrangement of the buffer 2 can effectively isolate different fluids or pressure areas, ensure unidirectional flow of the fluid, prevent backflow, and improve the sealing and reliability of the system.

[0052] See also Figures 1 to 5 As shown, the first end of the first tube body 3 extends into the second tube body 4 and extends to the second end of the second tube body 4. The outer wall of the second end of the first tube body 3 is provided with a connecting cover 301. The first end of the second tube body 4 extends toward the second end of the first tube body 3 and is detachably connected to the connecting cover 301.

[0053] Specifically, since the shell 1 is formed by connecting two tubes, the bypass chamber 12 formed is annular, so the buffer 2 is set in the bypass chamber 12 by means of a sleeve tube, the connecting cover 301 is provided with an internal thread, and the first end of the second tube 4 is provided with an external thread. When installing the buffer, the seal 202, the water retaining member 203 and the sealing ring are first sleeved on the outer wall of the first tube 3, the seal 202 is fixedly connected to the second end of the first tube 3, the seal 202 is close to the second end of the first tube 3, the first end of the first tube 3 is extended into the second tube 4, the second end of the second tube 4 is extended toward the first tube 3, the second tube 4 is rotated, and the second tube 4 is threadedly connected to the connecting cover 301. Since the connecting cover 301 is provided, not only is the bypass chamber 12 sealed from the first inlet and outlet 101, but the elastic member 201 can also be connected to the connecting cover 301.

[0054] In other embodiments, by connecting the first tube body 3 and the second tube body 4, a stable overall structure is formed, which can effectively withstand internal and external pressures and water flow impacts, thereby enhancing the stability of the system. The design of the connecting cover 301 makes the installation and disassembly of the entire buffer more convenient, and the user can quickly perform maintenance and replacement, reducing maintenance costs and time. The threaded connection between the connecting cover 301 and the second tube body 4 provides good sealing performance, ensuring the seal between the bypass chamber 12 and the first inlet and outlet 101 to prevent leakage. During the installation process, the user only needs to put the sealing member 202, the water retaining member 203 and the sealing ring on the first tube body 3, and then connect the second tube body 4 to the connecting cover 301 by rotating it, which simplifies the installation steps.

[0055] See also Figures 1 to 5 As shown, the axial length of the first tube body 3 is smaller than the axial length of the second tube body 4, and a bypass branch 13 is formed between the first end of the first tube body 3 and the inner wall of the second tube body 4. One end of the bypass branch 13 is connected to the second inlet and outlet 102, and the other end of the bypass branch 13 is connected to the bypass chamber 12.

[0056] In this embodiment, the bypass branch 13 can guide the fluid into the bypass chamber 12, thereby meeting the flow rate requirements of the system and improving the flexibility and efficiency of the system.

[0057] See also Figures 1 to 5 As shown, a water purifier includes a buffer, which is the buffer mentioned above.

[0058] As a specific implementation, specifically, a connector is provided at the second end of the first tube body 3, and a connector is provided at the second end of the second tube body 4. The two connectors are respectively connected to the water outlet and the faucet of the water purifier.

[0059] Specifically, water flows through the water pipe and enters the bypass branch 13, and then enters the bypass chamber 12 through the bypass channel. When the smart faucet solenoid valve is closed instantly, the water flow suddenly changes from a flowing state to a static state, and the impact force generated acts on the seal 202, pushing the seal 202 to overcome the elastic part 201 and move upward, buffering the impact of the water flow, reducing the impact force of the water flow on the pipeline and the solenoid valve, and preventing the faucet from shaking; when the smart faucet is turned on, water flows out from the faucet outlet, the water pressure in the buffer drops, and the seal 202 moves back to the bottom of the bypass chamber 12 under the push of the elastic part 201.

[0060] In this embodiment, the retractable nature of the buffer 2 absorbs the impact force generated by water hammer, reducing its direct impact on the pipelines and solenoid valves. When water flow suddenly stops or pressure suddenly changes, the buffer 2's retractable motion mitigates the rapid change in water pressure, thereby reducing the impact on the system. This helps protect the pipelines, solenoid valves, and other system components, extending their service life. When water pressure decreases or ceases, the buffer 2 drains residual water from the bypass chamber 12, keeping the system dry and clean. Once water pressure returns, the buffer 2 automatically resets, preparing for the next water flow buffering operation without requiring human intervention. Through flow diversion and the retractable nature of the buffer 2, the buffer effectively absorbs and reduces the impact force generated by water hammer, thereby protecting the pipelines and solenoid valves from damage. Furthermore, because the buffer absorbs the kinetic energy of the water flow, it reduces the impact of the water flow on the pipelines and solenoid valves, extending their service life and reducing maintenance and replacement costs.
