[0043] When scale appears in the pipes of beverage equipment, such as coffee machines, a descaling agent is usually added to the water tank of the coffee machine to descale the entire coffee machine pipes. The descaling agent needs to be dissolved during use. If the descaling agent is not completely dissolved, the descaling effect is poor and the descaling may be deposited inside the coffee machine, causing other problems. That is, the existing beverage equipment has the problem of inconvenient descaling.

[0044] In view of this, the utility model proposes a filter element assembly for a beverage device with a water tank, the filter element assembly comprising a filter element and a mounting structure, and the mounting structure is arranged in the water tank. The beverage device is used to make beverages, including but not limited to conventional equipment such as coffee machines, milk tea machines and tea machines. Specifically, the filter element is arranged in the water tank to filter the water in the water tank on a daily basis, so as to timely absorb and remove particles such as calcium carbonate and magnesium carbonate in the water, thereby avoiding the inconvenience caused by the use of a descaling agent.

[0045] Please refer to Figures 1 to 6 ,in Figure 2 The arrow in the figure indicates the direction of water flow; in one embodiment of the utility model, the filter element comprises:

[0046] The housing 10 is detachably connected to the mounting structure and is provided with a filter chamber 10a and a post-filter chamber 10b which are connected to each other. The water outlet of the post-filter chamber 10b is used to communicate with the water outlet hole 31 of the water tank 30, and the water inlet of the filter chamber 10a is used to communicate with an external water source; and

[0047] The filter material 20 is disposed in the filter cavity 10a.

[0048] Specifically, during the external water supply process of the water tank during daily use of the beverage equipment, raw water flows into the filter element from the water inlet of the filter chamber 10a, and is adsorbed and filtered by the filter material 20 in the filter chamber 10a to form purified water, which is then supplied to the outside through the water outlet of the post-filtration chamber 10b.

[0049] The technical solution of the utility model, through the filter material 20 arranged in the filter chamber 10a, can adsorb and filter the raw water flowing through the filter chamber 10a, so as to adsorb particles such as calcium carbonate and magnesium carbonate in the water, avoid these particles from being adsorbed and deposited on the inner wall of the pipe to cause scaling, and thus avoid the inconvenience caused by the use of descaling agents.

[0050] In one embodiment, the water inlet of the filter chamber 10a optionally includes an end water inlet 10d provided on the end surface and a side water inlet 10c provided on the side surface, and the end water inlet 10d and the side water inlet 10c are used to connect to an external water source. In this way, by providing water inlets on both the side and the end surface of the filter chamber 10a, the water inlet flow cross-sectional area of ​​the raw water can be increased, and under the condition of the same water resistance of the filter element, the flow rate of purified water can be effectively increased, thereby improving the user experience. Of course, in other embodiments, only one of the end water inlet 10d and the side water inlet 10c can be provided.

[0051] Please refer to Figure 6 , the water inlet of the filter chamber 10a is located at the bottom of the water tank 30. In this way, even when the water level in the water tank 30 is very low, that is, when the amount of water in the water tank 30 is very small, the water in the water tank 30 can still supply water to the filter element. Of course, in other embodiments, the water inlet of the filter chamber 10a can also be located in the middle or top of the water tank 30, and a water inlet pipe is provided in the water tank 30, the upper end of the water inlet pipe is connected to the water inlet of the filter chamber 10a, and the lower end of the water inlet pipe is located at the bottom of the water tank 30, so that the water at the bottom of the water tank 30 can flow from the water inlet pipe to the water inlet of the filter chamber 10a.

[0052] In one embodiment, the filter chamber 10a is optionally arranged around the periphery of the post-filter chamber 10b, and the side water inlet 10c is arranged on the outer peripheral surface of the filter chamber 10a and is located at the end where the end water inlet 10d is located. In this way, under the condition of the same filter element volume, the volume of the filter chamber 10a can be effectively increased, thereby improving the adsorption and filtration capacity and efficiency of the filter material 20 in the filter chamber 10a. Of course, in other embodiments, the post-filter chamber 10b and the filter chamber 10a can be arranged side by side in the length direction of the filter element, or the post-filter chamber 10b and the filter chamber 10a can be arranged side by side in the width direction of the filter element; or the post-filter chamber 10b can be arranged around the periphery of the filter chamber 10a.

[0053] In one embodiment, the housing 10 includes a shell 11 and a water outlet pipe 12 which are separately arranged. The water outlet pipe 12 is arranged in the middle of the shell 11. The post-filter chamber 10b is at least partially arranged in the water outlet pipe 12. The water outlet of the post-filter chamber 10b is arranged in the water outlet pipe 12. The water outlet pipe 12 and the shell 11 jointly enclose the filter chamber 10a. In this way, the structure is simple and easy to implement, and it is helpful to reduce the manufacturing cost of the filter element. Of course, in other embodiments, the shell 11 and the water outlet pipe 12 can also be integrally formed, such as integrally formed by injection molding.

[0054] It is worth mentioning that, in one embodiment, optionally, in the direction from the water inlet of the water outlet pipe 12 to the water outlet of the water outlet pipe 12, the diameter of the shell 11 is gradually reduced, and the diameter of the water outlet pipe 12 is gradually increased. That is, in this embodiment, the shell 11 and the water outlet pipe 12 are both designed with variable diameters. In this way, the width of the filter chamber 10a can be gradually reduced in the direction from the water inlet of the water outlet pipe 12 to the water outlet of the water outlet pipe 12, so that the filter material 20 has a greater distribution density at the lower end of the filter chamber 10a, so that the raw water is subjected to good filtering after flowing into the water inlet of the filter chamber 10a, thereby improving the filtering effect of the filter element. Of course, in other embodiments, only one of the shell 11 and the water outlet pipe 12 can be designed with a variable diameter, and the other one can not be designed with a variable diameter; for example, only the diameter of the water outlet pipe 12 is gradually increased in the direction toward its water outlet.

[0055] It is worth mentioning that in the embodiment in which the water outlet pipe 12 is designed with a variable diameter, the housing 11 and the water outlet pipe 12 are separately provided, which can facilitate the manufacturing of the water outlet pipe 12 and the housing 11, thereby helping to reduce the manufacturing cost of the filter element. Of course, in other embodiments, the housing 11 and the water outlet pipe 12 can also be integrally formed, and the water outlet pipe 12 can be designed with a variable diameter.

[0056] In one embodiment, the side water inlet 10c and the end water inlet 10d are optionally provided in a grid hole structure, and the housing 11 directly forms the side water inlet 10c and the end water inlet 10d. In this way, the structure of the filter element can be simplified and its manufacturing cost can be reduced. Of course, in other embodiments, the side water inlet 10c and / or the end water inlet 10d can also be provided in the form of a large through hole, and the housing 10 also includes a filter screen or filter cotton cloth covered on the side water inlet 10c and the end water inlet 10d.

[0057] In one embodiment, the housing 10 may further include a filter structure 13 having a plurality of filter holes, the filter structure 13 being disposed at the water inlet of the water outlet pipe 12, and the water inlet of the water outlet pipe 12 being connected to the water outlet of the filter chamber 10a through the filter holes. Specifically, the filter material 20 may be configured as filter particles, such as activated carbon particles and resin particles, which are not specifically limited in the present application. Furthermore, the pore size of the filter holes of the filter structure 13 is smaller than the particle size of the filter material 20 to prevent the filter material 20 from following the water into the water outlet pipe 12. Thus, by providing the filter structure 13 at the water inlet of the water outlet pipe 12, the structure is simple and easy to implement. Of course, in other embodiments, a filter cotton cloth may also be provided in the filter chamber 10a to confine the filter material 20 in the filter chamber 10a.

[0058] In one embodiment, the filter structure 13 is optionally configured as a sintered mesh filter cap, which is sleeved on the end of the water outlet pipe 12, and the post-filter cavity 10b is partially arranged on the sintered mesh filter cap. In this way, not only is the structure simple and easy to install, but the flow cross-sectional area of ​​the filter structure 13 can also be increased, thereby reducing the water resistance of the filter element. Of course, in other embodiments, the filter structure 13 can also be configured as filter cotton cloth, etc.

[0059] In one embodiment, the first end wall of the housing 11 is optionally provided with a mounting hole 111, the outlet end of the water outlet pipe 12 extends out of the mounting hole 111, and is provided with a water outlet of the post-filter chamber 10b, and the end water inlet 10d is arranged around the outer periphery of the mounting hole 111. That is, the water outlet of the water outlet pipe 12, the side water inlet 10c and the end water inlet 10d are arranged at the same end of the filter element, and the raw water flows into the filter chamber 10a from the first end of the filter element, and flows into the post-filter chamber 10b from the filter chamber 10a at the second end, and then flows out of the first end through the water outlet of the water outlet pipe 12 (i.e., the post-filter chamber 10b). In this way, the distance that the raw water needs to pass in the filter chamber 10a can be extended, thereby improving the adsorption and filtration effect of the filter material 20 on the raw water, and by arranging the water outlet of the water outlet pipe 12, the side water inlet 10c and the end water inlet 10d at the same end of the filter element, the structure of the filter element and the water tank 30 can also be simplified. Of course, in other embodiments, the water outlet of the water outlet pipe 12 may also be disposed on the second end wall of the housing 11 , and the second end wall and the first end wall are disposed opposite to each other in the length direction of the housing 11 .

[0060] For details, please refer to Figure 6 ,in Figure 6 Only part of the structure of the water tank 30 is shown; when the filter element is used in the water tank 30, the end water inlet 10d and the side water inlet 10c are both located at the lower end of the filter element and immersed in the water body of the water tank 30, so that the water in the water tank 30 can enter the filter cavity 10a through the end water inlet 10d and the side water inlet 10c under the action of atmospheric pressure, and flow through the filter structure 13 located at the upper end of the filter element and enter the water outlet pipe 12, and then flow out from the water outlet located at the lower end of the water outlet pipe 12 and be supplied to the outside.

[0061] In one embodiment, optionally, the inner edge of the mounting hole 111 is provided with a mounting ring rib 112, and the water outlet pipe 12 is provided with a clamping protrusion 121 corresponding to the mounting ring rib 112, and the clamping protrusion 121 is clamped on the mounting ring rib 112. In this way, the water outlet pipe 12 and the housing 11 are fixed by clamping, and the structure is simple and easy to assemble. Of course, in other embodiments, the water outlet pipe 12 and the housing 11 can also be fixed by screwing, riveting or welding.

[0062] In one embodiment, the mounting ring rib 112 includes a first ring segment 113 and a second ring segment 114, the first ring segment 113 connects the second ring segment 114 and the first end wall, and is gradually reduced in diameter in the direction close to the second ring segment 114, the water outlet pipe 12 includes a first pipe segment 122 and a second pipe segment 123, the first pipe segment 122 is adapted to be inserted in the first ring segment 113, and is provided with a water outlet of the post-filter chamber 10b, and the second pipe segment 123 is connected to an end of the first pipe segment 122 away from the water outlet, and is provided with a clamping protrusion 121. In this way, the first ring segment 113 can play a guiding role in the process of the water outlet pipe 12 being inserted from the mounting hole 111 into the interior of the housing 11, so as to facilitate the installation of the water outlet pipe 12, and can play a limiting role after the water outlet pipe 12 is installed in place, and cooperates with the clamping protrusion 121, so that the water outlet pipe 12 can be stably installed on the housing 11. Of course, in other embodiments, the first ring segment 113 with a tapered diameter may not be provided, that is, the diameter of the mounting annular rib 112 remains unchanged.

[0063] In one embodiment, the side water inlet 10c and the first ring segment 113 are optionally arranged opposite to each other and spaced apart in the radial direction of the water outlet pipe 12. In this way, when the raw water flowing in from the side water inlet 10c hits the first ring segment 113, part of the water flow will turn more smoothly along the inclined direction of the first ring segment 113, thereby reducing the impact of the water flow on the water outlet pipe 12. Of course, in other embodiments, the side water inlet 10c and the first ring segment 113 may also be spaced apart in the axial direction of the water outlet pipe 12.

[0064] In one embodiment, optionally, two side water inlets 10c are provided, and the two side water inlets 10c are provided on opposite sides of the housing 11. In this way, the water inlet flow cross-sectional area of ​​the raw water can be further increased, and the flow rate of the purified water can be increased. Of course, in other embodiments, the number of the side water inlet 10c can be only one, or three or more.

[0065] In one embodiment, the outer peripheral surface of the water outlet end of the water outlet pipe 12 is optionally provided with an annular groove 124, and is used to be plugged with the water outlet hole 31 of the water tank 30. The filter element also includes a sealing ring 14 sleeved in the annular groove 124, and the sealing ring 14 elastically abuts against the hole wall of the water outlet hole 31. In this way, the water outlet hole 31 is isolated from the inside of the water tank 30 by the sealing ring 14, which can prevent the raw water in the water tank 30 from flowing out of the water outlet hole 31 or flowing into the water outlet pipe 12 to pollute the purified water. The structure is simple and easy to implement.

[0066] Please refer to Figure 1 , Figure 5 and Figure 6 In one embodiment, the mounting structure optionally includes a limiting rib 32 protruding from the inner wall of the water tank 30, and the side wall of the housing 11 has an extended wall portion 115 extending beyond the first end wall, and the extended wall portion 115 is provided with a limiting groove 116, and the limiting groove 116 is used for plugging the limiting rib 32 of the water tank 30. Specifically, the outer peripheral surface of the water outlet 31 of the water tank 30 is connected with the limiting rib 32, and when the filter element is inserted into the water tank 30, the limiting groove 116 can be sleeved on the limiting rib 32, so as to realize the plug-in installation of the filter element. Of course, in other embodiments, the filter element and the water tank can also be detachably installed by screwing. For example, the mounting structure includes a screw connection column provided on the inner wall of the water tank, the screw connection column is provided with a threaded hole, and the housing of the filter element is provided with an assembly hole corresponding to the threaded hole, and the screw passes through the assembly hole and is locked on the threaded hole. The housing 11 can also be fixed to the water tank 30 by riveting or welding.

[0067] Further optionally, the inner wall surface of the water tank 30 is further provided with a positioning rib 33, which is connected to the end of the limiting rib 32 away from the water outlet 31, and the upper edge of the positioning rib 33 is higher than the upper edge of the limiting rib 32, and can abut against the outer peripheral surface of the housing 11. In this way, the position of the filter element can be limited by the positioning rib 33, avoiding the risk of the filter element shaking in the horizontal direction in the water tank 30, thereby improving the installation stability and reliability of the filter element. Of course, in other embodiments, the positioning rib 33 may not be provided.

[0068] In one embodiment, a plurality of limit grooves 116 are optionally provided, and the plurality of limit grooves 116 are spaced apart along the circumference of the housing 11, and a guide wall portion 117 is defined between two adjacent limit grooves 116, and the surface of the guide wall portion 117 away from the first end wall is configured as an outward convex arc surface. In this way, the guide wall portion 117 with the lower surface being an outward convex arc surface can play a good guiding role in the process of inserting the limit rib 32 into the limit groove 116, so that when the filter element is installed into the water tank 30 from any angle, the limit groove 116 can automatically align with the limit rib 32, achieving the effect of blind installation operation, thereby improving the convenience of installation of the filter element.

[0069] Optionally, in one embodiment, at least one limiting groove 116 can connect the end water inlet 10d and the water tank 30. That is, when some limiting grooves 116 are not plugged into the limiting ribs 32, they can be used to connect the water tank 30, so that the raw water in the water tank 30 can flow into the end water inlet 10d through these limiting grooves 116. In this way, the structure of the filter element can be simplified and its manufacturing cost can be reduced.

[0070] Further optionally, the outer surface of the first end wall of the housing 11 is provided with a reinforcing rib 118, and the reinforcing rib 118 connects the first end wall and the extension wall portion 115. In this way, the extension arm portion is pulled by the reinforcing rib 118 on the first end wall, so that the structural strength of the extension wall portion 115 can be improved, thereby improving the installation stability of the filter element on the water tank 30.

[0071] In one embodiment, the filter element further includes a time recording disk 15, which is exposed on the housing 10. Specifically, the time recording disk 15 is provided with date numbers and / or scales, such as January to December, and uses a pointer or a display window to display a specific date, so that the user can record the time and confirm the replacement time of the filter element. Specifically, the time recording disk 15 is provided on the second end face of the housing 11, that is, it is provided at the opposite ends of the filter element with the water outlet. Of course, in other embodiments, the time recording disk 15 may not be provided.

[0072] Further optionally, the time recording disk 15 covers the opening at the second end of the housing 11, and the upper end of the water tank 30 is correspondingly provided with a positioning groove, and the outer periphery of the time recording disk 15 is adapted to be embedded in the positioning groove. In this way, the upper and lower ends of the filter element are both plugged and fixed to the water tank 30, which can improve the installation stability of the filter element. Of course, in other embodiments, only the lower end of the filter element can be plugged into the water tank 30.

[0073] In one embodiment, the filter element may further include a baffle (not shown in the drawings) movably disposed on the housing 10, and the baffle may close or open the side water inlet 10c.
