[0033] Compared with the existing filtering devices, the filtering device provided by the utility model is provided with a sealing member. When the liquid to be filtered is injected into the cup body, the sealing member can achieve a sealing effect to prevent the liquid from leaking.

[0034] First embodiment

[0035] Reference Figures 1 to 6 The first embodiment of the utility model provides a filtering device, which includes a cup body 1 and a cup cover assembly 2. The cup body 1 is provided with an opening, and the cup body 1 includes a filter screen 12.

[0036] It is understandable that the filter screen 12 may be provided in plurality or only one. In the present embodiment, the filter screen 12 is provided as an integrally formed cylindrical structure.

[0037] Reference Figures 1 to 3 , the cup cover assembly 2 is detachably arranged at the opening of the cup body 1, and is used to seal the opening. In another specific embodiment, the cup cover assembly 2 is hingedly connected to the opening of the cup body 1. The cup cover assembly 2 includes a fixing member 21 and a sealing member 20. The fixing member 21 is provided with a through hole 213, and the through hole 213 serves as a channel for liquid to enter the cup body 1. The sealing member 20 is arranged on the fixing member 21, and the projection of the sealing member 20 covers the through hole 213. The sealing member 20 is made of a flexible material.

[0038] It can be understood that the projection of the seal 20 covering the through hole 213 here may be a projection from top to bottom or from bottom to top, that is, the seal may be arranged on the upper surface of the fixing member or on the lower surface of the fixing member.

[0039] Reference Figures 2 to 4 In this embodiment, a protruding structure 214 is provided at the through hole 213 . When the cup cover assembly 2 is connected to the cup body 1 , the protruding structure 214 is located on a side of the cup cover assembly 2 facing the cup body 1 .

[0040] Furthermore, the protruding structure 214 is provided with a plurality of through holes 215. In this embodiment, the plurality of through holes 215 are evenly distributed axially on the protruding structure 214. In another specific embodiment, the through holes 215 can be provided as an annular structure.

[0041] It is understandable that the present filtering device needs to be used in conjunction with an external device, and an injection portion is provided on the external device, and the injection portion is used to deliver the solution to be filtered into the cup body 1. The inner contour of the protruding structure 214 matches the outer contour of the injection portion. When the solution is injected into the cup body 1, the injection portion sequentially passes through the seal 20 and the through hole 213, and is finally inserted into the protruding structure 214. Since the seal 20 is made of a flexible material, in this embodiment, the seal 20 is made of a silicone material, and the portion of the seal 20 corresponding to the through hole 213 is thinner than other portions, which can make it easier for the injection portion to pass through. In other embodiments, the seal 20 can be made of other materials with a sealing effect.

[0042] When it is necessary to filter the solution, the solution to be filtered injected by the injection part passes through the through hole 215 on the protruding structure 214 and flows into the cup body 1. Part of the solution passes along the filter screen 12 of the cup body 1. The bottom of the filtering device should be equipped with a device for carrying the filtered liquid. The impurities in the solution are filtered by the filter screen 12 and remain in the cup body 1. When it is not necessary to filter the solution, the injection part is detached from the filtering device, and the part of the seal 20 punctured by the injection part will return to a flat state.

[0043] Reference Figure 4 In this embodiment, the cup cover assembly 2 further includes a first connecting member 217. The fixing member 21 is connected with the first connecting member 217 to form an annular structure. The bottom of the annular structure is provided with an annular groove 219. In this embodiment, the opening edge of the cup body 1 is provided with an annular protrusion 11. The annular protrusion 11 extends in the circumferential direction of the cup body 1, and the annular protrusion 11 is adapted to the annular groove 219. During assembly, the annular protrusion 11 of the cup body 1 is snapped into the annular groove of the cover body, so that the cup body 1 and the cup cover assembly 2 can be fixedly connected.

[0044] Reference Figures 5 and 6 The fixing member 21 is provided with a plurality of second limiting posts 216, and the first connecting member 217 is provided with a plurality of second limiting holes 218, and the second limiting posts 216 are adapted to the second limiting holes 218. The fixing member 21 is fixedly connected to the first connecting member 217 by the cooperation between the second limiting posts 216 and the second limiting holes 218.

[0045] Furthermore, the fixing member 21 is provided with a plurality of first limiting holes 212, and the sealing member 20 is provided with a plurality of first limiting columns 202, and the first limiting holes 212 are adapted to the first limiting columns 202. The sealing member 20 is fixed to the fixing member 21 by the first limiting holes 212 cooperating with the first limiting columns 202.

[0046] In this embodiment, the fixing member 21 is provided with a clamping portion 211, and the clamping portion 211 is symmetrically arranged on the fixing member 21. It can be understood that the filtering device needs to be used together with an external device, and the external device referred to here can be a coffee machine, a tea maker, etc. The clamping portion 211 is used to connect the external device to fix the filtering device, and the external device needs to be set in the card slot matched by the clamping portion 211. Before performing the filtering work, the position of the filtering device is fixed and positioned first, so that the injection part can be smoothly aligned with the through hole 213.

[0047] Furthermore, the cup body 1 further comprises a cup bottom 13 and a second connecting member 14 , the cup bottom 13 is connected to the filter screen 12 via the second connecting member 14 , and the filter screen 12 is connected to the annular protrusion 11 .

[0048] The utility model also provides a coffee machine, which includes the filtering device described above. By fixing the filtering device on the coffee machine, the coffee liquid brewed by the coffee machine can be filtered. The filtering device is provided with a sealing member 20 in the cup cover assembly. When the liquid to be filtered is injected into the cup body, the through hole 213 of the sealing member 20 and the fixing member 21 needs to be penetrated. The sealing member 20 can be closely attached to the injection part of the coffee machine, which can prevent the solution from leaking, protect the components of the coffee machine, and extend its service life.

[0049] Second embodiment

[0050] Reference Figure 7 and Figure 8 The difference between this embodiment and the first embodiment lies in the number of through holes 213 on the fixing member 21 .

[0051] In this embodiment, the fixing member 21 is provided with a plurality of through holes 213 , wherein one through hole 213 is located at the center of the fixing member 21 , and the remaining through holes 213 are symmetrically arranged on the fixing member 21 with the center line of the fixing member 21 as the axis of symmetry.

[0052] In this embodiment, the protruding structure 214 is only provided on the through hole 213 at the center, and the protruding structure 214 is not provided on the other through holes 213. In another specific embodiment, the protruding structure 214 is provided on a plurality of the through holes 213. It can be understood that, regardless of whether the protruding structure 214 is provided, the injection part will penetrate the sealing member 20 and the through hole 213 and deliver the solution to be filtered into the cup body 1.

[0053] By adjusting the number of through holes 213 on the fixing member 21, it can be adapted to a coffee machine with multiple injection parts, and the multiple injection parts can simultaneously deliver the solution to be filtered into the cup body 1, which can improve the efficiency of filtering the solution.

[0056] The slit 201 can be set to any structure. In this embodiment, the slit 201 is set to a cross-shaped structure. In the first embodiment, the injection part of the coffee machine needs to apply a certain force to penetrate the sealing member 20. In this embodiment, by setting the slit 201 on the sealing member 20, the injection part of the coffee machine can easily pass through the sealing member 20 along the slit 201 without applying additional force.

[0057] Fourth embodiment

[0058] The difference between this embodiment and the second embodiment is that a plurality of slits 201 are provided on the sealing member 20 , and the plurality of slits 201 correspond one-to-one to the plurality of through holes on the fixing member 21 .

[0059] The slit 201 can be set to any structure. In this embodiment, the slit 201 is set to a cross structure.

[0060] In the second embodiment, the injection part of the coffee machine needs to exert a certain force to penetrate the sealing member 20. In this embodiment, by providing a slit 201 on the sealing member 20, the injection part of the coffee machine can easily penetrate the sealing member 20 along the slit 201 without applying additional force.

[0061] It is understandable that those skilled in the art can, under the guidance of the above embodiments, combine various implementation methods in the above embodiments to obtain technical solutions of multiple implementation methods.
