[0024] This utility model is also achieved through the following technical solution: a hydrogen-rich water dispenser, comprising:
[0025] The filter in any of the above embodiments;
[0026] A reverse osmosis assembly, wherein the reverse osmosis assembly is connected to the outlet of the filter;
[0027] A hydrogen mixing assembly, which is connected to the reverse osmosis assembly;
[0028] A booster pump is used to supply water to the inlet of the filter and drive the water to the outlet.
[0029] Compared with the prior art, this utility model has the following advantages:
[0030] This utility model provides a filter and a hydrogen-rich water dispenser, wherein the filter includes a housing, a filter element, and a sealing ring. The housing has an inlet and an outlet communicating with its interior, so that other components of the water dispenser, such as a booster pump, can supply water to the filter through the inlet, and other components of the water dispenser, such as a reverse osmosis assembly, can obtain water from the outlet. The filter element is housed within the housing and located between the inlet and the outlet; so that water flowing from the inlet to the outlet is filtered by the filter element, ensuring sufficient filtration. The housing includes an outer shell and an end cap. One end of the outer shell is an open side, facilitating the installation and removal of the filter element through the open side.

Detailed Implementation
[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0042] Example 1:
[0043] like Figures 1-6 A filter is shown, comprising a housing 10, a filter element 20, and a sealing ring 30. The housing 10 has an inlet 10A and an outlet 10B communicating with its interior, allowing other components of the water dispenser, such as a booster pump, to supply water to the filter through the inlet 10A, and allowing other components of the water dispenser, such as a reverse osmosis unit, to obtain water through the outlet 10B. The filter element 20 is housed within the housing 10 and located between the inlet 10A and the outlet 10B, ensuring that all water flowing from the inlet 10A to the outlet 10B is filtered by the filter element 20, thus facilitating thorough filtration. The housing 10 includes an outer shell 11 and an end cap 12, one end of which is an open side 11A, facilitating the installation and removal of the filter element 20 through the open side 11A. A portion of the end cap 12 is fitted over the outer shell 11 to seal the opening side 11A, while the other portion of the end cap 12 presses the sealing ring 30 against the opening side 11A. This pressing of the sealing ring 30 against the opening side 11A by the other portion of the end cap 12 improves the sealing performance at the connection between the end cap 12 and the outer shell 11, reducing the risk of liquid leakage. The inner circumference of the end cap 12 is provided with a protrusion 12A, and the outer circumference of the outer shell 11 has a corresponding groove 116. The groove 116 includes a first section 1161 and a second section 1162 connected to each other. The end of the first section 1161 away from the second section 1162 is used for the protrusion 12A to slide into the groove 116. The first section 1161 extends axially along the filter, and the second section 1162 extends circumferentially along the filter. This makes it easier to insert the protrusion 12A into the first segment 1161, move it to the second segment 1162 and rotate it along the second segment 1162 so that the protrusion 12A disengages from the first segment 1161, thereby locking the end cap 12 and the outer shell 11. This makes it easier to fix the end cap 12 and the outer shell 11 compared to threaded connections and other methods.
[0044] With the above structure, the filter provided by this utility model can facilitate filter assembly by moving the protrusion 12A to the second section 1162 to lock the end cap 12 and the outer shell 11; at the same time, by moving the protrusion 12A to the first section 1161, it is easy to separate the outer shell 11 and the end cap 12, thus facilitating the replacement of the filter element 20. This solves the technical problems of existing filters being inconvenient to disassemble and the filter element 20 being inconvenient to replace.
[0045] Optionally, the end cap 12 includes a cap body 121 and a side portion 122. The cap body 121 has a sealing ring 30 sandwiched between the opening side 11A and the cap body 121; the side portion 122 is arranged around the edge of the cap body 121 and can rotate around the circumference of the cap body 121, and the protrusion 12A protrudes from the inner surface of the side portion 122.
[0046] Understandably, the above structure allows the cover 121 to remain stationary relative to the housing 11 during filter disassembly and installation by switching the protrusion 12A between the first section 1161 and the second section 1162 via the side 122. This prevents the cover 121 from rotating relative to the sealing ring 30, thus reducing the risk of wear on the sealing ring 30 due to rotation of the cover 121 under pressure. This extends the service life of the filter housing 10.
[0047] Optionally, the side portion 122 includes a body 122A, a first boss 122B, and a locking block 122C. The body 122A is wrapped around the edge of the cover 121; the first boss 122B protrudes from the inner periphery of the body 122A; the locking block 122C protrudes from the inner periphery of the body 122A and can drive the body 122A to elastically deform along the radial direction of the filter. Along the axial direction of the filter, the cover 121 is locked between the locking block 122C and the first boss 122B.
[0048] In some embodiments, the snap-fit blocks 122C are a plurality of blocks arranged circumferentially around the body 122A on the inner peripheral side of the body 122A.
[0049] Understandably, by setting the snap-fit block 122C so that the side part 122 can be connected to the cover 121 by snap-fit, the assembly of the end cover 12 is facilitated without affecting the rotation of the side part 122 relative to the cover 121.
[0050] Optionally, the housing 11 includes a clearance section 111 and a connecting section 112 arranged along the axial direction of the filter. The radial dimension of the clearance section 111 is smaller than the radial dimension of the connecting section 112, so as to form a first stepped surface 114 on the surface of the housing 11. One end of the first section 1161 away from the second section 1162 is disposed on the first stepped surface 114. In the radial direction of the filter, the snap-fit block 122C is located between the inner peripheral side of the body 122A and the outer peripheral side of the clearance section 111.
[0051] In some embodiments, the outer peripheral side of the connecting segment 112 is adapted to the inner peripheral side of the body 122A to prevent the end cap 12 from being offset during the assembly of the end cap 12 and the housing 11.
[0052] Understandably, by setting the avoidance section 111, the risk of interference between the outer casing 11 and the snap-fit block 122C during installation can be reduced, and the structure is simple and easy to implement.
[0053] Optionally, the housing 11 also includes a body segment 113 along the axial direction of the filter. The body segment 113 is located at the end of the connecting segment 112 away from the avoidance segment 111. The radial dimension of the connecting segment 112 is smaller than the radial dimension of the body segment 113, so as to form a second stepped surface 115 on the surface of the housing 11. The second stepped surface 115 is used to abut against the body 122A. Thus, the body 122A restricts the end cap 12 from getting too close to the opening side 11A, thereby reducing the risk of the end cap 12 crushing the sealing ring 30.
[0054] Optionally, the side portion 122 also includes a pin 122D. The body 122A has a through hole extending radially through the body 122A. The pin 122D passes through the through hole and protrudes from the inner periphery of the body 122A to form a protrusion 12A. Thus, after the body 122A and the cover 121 are assembled, the protrusion 12A can be formed by assembling the pin 122D to prevent the protrusion 12A from interfering with the assembly of the body 122A and the cover 121. The structure is simple and easy to implement.
[0055] Optionally, a second protrusion 121A is provided on the side of the cover 121 away from the outer shell 11, and the liquid outlet 10B is provided on the side of the second protrusion 121A away from the cover 121. The cross-section of the second protrusion 121A is polygonal. This allows the cover 121 to remain stationary by holding the second protrusion 121A when the side 122 is rotated relative to the cover 121, facilitating the assembly of the end cap 12 and the outer shell 11.
[0056] Optionally, a portion of the opening side 11A is recessed to form a receiving groove 11B, within which the sealing ring 30 is located. By providing the receiving groove 11B, the position of the sealing ring 30 is restricted during the sealing and tightening process, reducing the risk of the sealing ring 30 becoming loose and crushed.
[0057] Optionally, the side portion 122 of the second segment 1162 away from the outer casing 11 is recessed to form a limiting groove 1162A, which is used to accommodate a portion of the protrusion 12A. Thus, when the booster pump of the water dispenser injects water into the casing 10, causing an increase in pressure within the casing 10 and posing a risk of separation between the end cap 12 and the outer casing 11, the limiting groove 1162A can restrict the movement of the protrusion 12A along the second segment 1162, preventing the connection between the end cap 12 and the outer casing 11 from failing.
[0058] This utility model also provides a hydrogen-rich water dispenser, including a filter, a reverse osmosis component, a hydrogen mixing component, and a booster pump as described in any of the above embodiments. The reverse osmosis component is connected to the outlet 10B of the filter; the hydrogen mixing component is connected to the reverse osmosis component; the booster pump is used to supply water to the inlet 10A of the filter and drive the water to move towards the outlet 10B.
[0059] The reverse osmosis membrane in the reverse osmosis filter can trap bacteria and viruses in the water, achieving a removal effect. The hydrogen mixing assembly includes an electrolyzer connected to the reverse osmosis filter. Specifically, the hydrogen mixing assembly also includes a hydrogen mixing pump and a water outlet. The hydrogen mixing pump is connected to the electrolyzer, and the water outlet is connected to the hydrogen mixing pump and the water outlet is connected to the magnetization assembly. The electrolyzer is used to electrolyze the water. The electrolyzed hydrogen ions mix with water molecules in the hydrogen mixing pump, and then flow into the magnetization assembly through the water outlet for magnetization and cutting.
[0060] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
