Abstract
Description
Technical Field
[0001] The present application relates to the field of household appliances, and in particular to a filtering device and a coffee machine. Background Art
[0002] The coffee machine has a filter device for extracting food materials and filtering the extract. In the prior art, the residue formed by the food powder extracted under high pressure is difficult to pour out directly from the filter device, which makes the use feel poor and also causes the problem of difficult cleaning, resulting in the easy breeding of bacteria in the filter device. Utility Model Content
[0003] The present application provides a filter device and a coffee machine, which can solve the problems in the prior art that food residues are difficult to pour out and the filter device is inconvenient to clean.
[0004] The first aspect of the present application provides a filtering device, comprising:
[0005] A bracket having a first accommodating cavity, an inner wall of the bracket being provided with a mounting portion, and along the radial direction of the bracket, the mounting portion extending toward the interior of the first accommodating cavity;
[0006] The filter screen is detachably installed in the first accommodating cavity, and the filter screen is overlapped and matched with the installation portion.
[0007] In the above scheme, the filter and the bracket are arranged into a detachable structure, which is convenient for the user to dump the food residue after removing the filter, and also convenient for the filter and the bracket to be cleaned separately, reducing sanitary dead corners, and can reduce the risk of bacterial growth caused by food residues, thereby improving the user's experience. Specifically, the inner wall of the bracket is provided with a mounting portion, and the mounting portion extends radially toward the inside of the first accommodating chamber along the bracket, which can provide support for the bottom wall of the filter. When the filter is overlapped on the mounting, the installation of the filter is realized, and the filter can be removed from the bracket by pushing the filter upward from the bottom through hole of the bracket. The above structure can simplify the steps of disassembling and assembling the bracket and the filter while ensuring the stability of the installation, thereby improving the convenience of use for the user.
[0008] In a possible design, the bracket further has an opening, and the filter can be separated from the first accommodating cavity through the opening; along the direction of the mounting portion pointing to the opening, the inner diameter of the bracket gradually increases.
[0009] In the above scheme, when the filter is placed in the first accommodating cavity, the inclined inner wall of the bracket can provide a guide for the filter, making it convenient for the filter to be overlapped onto the mounting portion; when the filter is taken out of the first accommodating cavity, the inclined inner wall of the bracket can reduce the friction between the filter and the filter, making it convenient for the filter to be quickly taken out, thereby improving the convenience of user operation.
[0010] In a possible design, along the direction in which the opening points toward the mounting portion, the thickness of the side wall of the bracket gradually increases.
[0011] In the above scheme, the side wall of the bracket is thick at the bottom and thin at the top, which can improve the structural strength of the matching part between the bracket and the filter. Even if the filter is frequently disassembled and assembled, the side wall of the bracket will not be deformed, thereby improving the structural stability of the bracket and extending the service life of the bracket.
[0012] In a possible design, the filter screen includes a bottom plate and a reinforcement wall, and the reinforcement wall is arranged around the circumference of the bottom plate.
[0013] In the above solution, the space enclosed by the bottom plate and the reinforcement wall is used to place food powder. Along the axial direction of the filter, the height of the reinforcement wall is greater than the height of the bottom plate, which can increase the overall structural strength of the filter and reduce the risk of deformation during the disassembly and assembly of the filter. Moreover, compared with the method of increasing the overall thickness of the filter, it can reduce the weight of the filter, reduce the production cost of the filter and the difficulty of installation.
[0014] In a possible design, along the axial direction of the filter screen, the height H1 of the reinforcing wall satisfies: 0 mm
[0015] In the above solution, when the height H1 of the reinforcing wall satisfies 0 mm
[0016] In a possible design, the inner diameter of the reinforcing wall gradually increases along the axial direction of the filter screen toward a direction away from the bottom plate.
[0017] In the above solution, the reinforcing wall is inclined so as to be wider at the top and narrower at the bottom, thereby reducing sanitary dead corners and facilitating cleaning by users.
[0018] In a possible design, the filtering device further includes a base having a second accommodating cavity, and the bracket is detachably installed in the second accommodating cavity.
[0019] In the above scheme, the base is used to cooperate with the coffee machine body for assembly and disassembly so as to install the bracket on the coffee machine body. When the bracket is installed in the second accommodating chamber, the extraction liquid flowing out of the bracket through hole can flow to the outside through the second accommodating chamber for the user to drink.
[0020] In one possible design, the base is provided with a lap joint; the bracket is also provided with a flange, and a receiving groove is formed between the flange and the outer wall of the bracket; the receiving groove is used to limit the radial movement of the lap joint along the bracket when the flange overlaps the lap joint.
[0021] In the above scheme, the flange is bent outward to form a receiving groove. When the bracket is installed in the second receiving cavity, the flange can overlap on the overlapping portion. At this time, at least part of the overlapping portion is located in the receiving groove. The side wall of the receiving groove is used to limit the radial movement of the overlapping portion along the bracket. Similarly, the overlapping portion is also used to limit the radial movement of the flange along the bracket. Therefore, the above structure is conducive to improving the installation stability of the bracket and the base.
[0022] In a possible design, a convex rib is provided on an outer wall of the bracket, and the convex rib abuts against an inner wall of the base.
[0023] In the above scheme, along the radial direction of the bracket, the convex rib protrudes toward the direction close to the inner wall of the base, and can abut against the inner wall of the base, thereby increasing the connection area between the bracket and the base, preventing the bracket from shaking along its own radial direction, and reducing the possibility of the bracket rotating relative to the base, which is conducive to improving the installation stability of the bracket. In addition, during the disassembly and assembly process of the bracket, the convex rib is used for frictional contact with the inner wall of the base, and the contact area between the two is small, which reduces the friction resistance and is conducive to improving the convenience of disassembly and assembly of the bracket.
[0024] A second aspect of the present application provides a coffee machine, comprising:
[0025] main body;
[0026] A filter device is detachably mounted on the main body, and the filter device is the filter device described above.
[0027] In the above solution, the filter device can be detachably connected to the main body, and the filter device itself can also be disassembled into multiple parts, which is convenient for pouring out food residues and facilitating cleaning by users.
[0028] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0053] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0054] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.
[0055] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
[0056] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.
[0057] The present application embodiment provides a filtering device that can be used in a coffee machine, such as Figure 1 and Figure 2 As shown, the filtering device includes a bracket 1 and a filter 2. The bracket 1 has a first accommodating cavity 10. The inner wall of the bracket 1 is provided with a mounting portion 11. Along the radial direction X of the bracket 1, the mounting portion 11 extends toward the inside of the first accommodating cavity 10. The filter 2 is detachably installed in the first accommodating cavity 10, and the filter 2 overlaps with the mounting portion 11.
[0058] In this embodiment, the bottom of the bracket 1 has a through hole, the first accommodating cavity 10 is connected to the outside through the through hole, and the filter screen 2 has a plurality of filter holes. Figure 3 and Figure 4 As shown, when the filter 2 is installed in the first accommodating chamber 10, the filter 2 is used to place food powder (such as coffee powder), and the first accommodating chamber 10 is used to contain liquid to extract the food powder. The obtained extract can flow through the filter hole to the through hole, and then flow through the through hole to the outside for users to drink. Since the food residue after extraction is difficult to pour out directly, it is not convenient to clean the filter 2 and the bracket 1, so the present application sets the filter 2 and the bracket 1 into a detachable structure, which is convenient for users to remove the filter 2 and then dump the food residue, and also convenient for the filter 2 and the bracket 1 to be cleaned separately, reducing sanitary dead corners, and can reduce the risk of bacterial growth caused by food residues, and improve the user's experience.
[0059] Specifically, Figure 4As shown, the inner wall of the bracket 1 is provided with a mounting portion 11, which extends along the radial direction X of the bracket 1 toward the inside of the first accommodating cavity 10, and can provide support for the bottom wall of the filter 2. When the filter 2 is overlapped on the mounting portion 11, the installation of the filter 2 is realized, and the filter 2 can be removed from the bracket 1 by pushing the filter 2 upward from the bottom through hole of the bracket 1. The above structure can simplify the steps of disassembling and assembling the bracket 1 and the filter 2 while ensuring the installation stability, thereby improving the convenience of use for users.
[0060] Among them, Figure 5 As shown, the mounting portion 11 can be arranged in a whole ring along the circumference of the bracket 1, or can be arranged in a plurality of split structures at intervals along the circumference of the bracket 1. The specific number can be 3, 4, 5, 6 or more, and the present application does not impose any limitation on this.
[0061] In a specific embodiment, Figure 4 As shown, the bracket 1 also has an opening 12 , through which the filter screen 2 can be separated from the first accommodating cavity 10 , and along the direction of the mounting portion 11 pointing to the opening 12 , the inner diameter of the bracket 1 gradually increases.
[0062] In this embodiment, the inner wall of the bracket 1 is inclined, and the interior of the first accommodating chamber 10 is wide at the top and narrow at the bottom. When the filter 2 is placed in the first accommodating chamber 10, the inclined inner wall of the bracket 1 can provide a guide for the filter 2, making it convenient for the filter 2 to be overlapped onto the mounting portion 11; when the filter 2 is taken out of the first accommodating chamber 10, the inclined inner wall of the bracket 1 can reduce the friction between the filter 2 and the filter 2, making it convenient for the filter 2 to be quickly taken out, thereby improving the convenience of user operation.
[0063] In a specific embodiment, Figure 4 As shown, along the direction from the opening 12 to the mounting portion 11 , the thickness of the side wall of the bracket 1 gradually increases.
[0064] In this embodiment, the side wall of the bracket 1 is thick at the bottom and thin at the top, which can improve the structural strength of the matching part of the bracket 1 and the filter 2. Even if the filter 2 is frequently disassembled and assembled, the side wall of the bracket 1 will not be deformed, thereby improving the structural stability of the bracket 1 and extending the service life of the bracket 1.
[0065] In a specific embodiment, Figure 6 As shown, the filter screen 2 includes a bottom plate 21 and a reinforcement wall 22 , and the reinforcement wall 22 is arranged around the bottom plate 21 in a circumferential direction.
[0066] In this embodiment, Figure 4As shown, the space enclosed by the bottom plate 21 and the reinforcing wall 22 is used to place food powder. Along the axial direction Z of the filter 2, the height of the reinforcing wall 22 is greater than the height of the bottom plate 21, which can increase the overall structural strength of the filter 2 and reduce the risk of deformation during the disassembly and assembly of the filter 2. Moreover, compared with the method of increasing the overall thickness of the filter 2, the weight of the filter 2 can be reduced, and the production cost and installation difficulty of the filter 2 can be reduced.
[0067] Specifically, Figure 4 As shown, along the axial direction Z of the filter screen 2, the height H1 of the reinforcing wall 22 satisfies: 0 mm
[0068] If the height H1 of the reinforcing wall 22 is too large (for example, greater than 7 mm), the height of the filter screen 2 will be too large, making it inconvenient to disassemble and assemble, and will also increase the volume and weight of the filter screen 2, but will not have a significant effect on improving the strength performance.
[0069] Therefore, when the height H1 of the reinforcing wall 22 satisfies 0 mm
[0070] The filter holes are arranged on the bottom plate 21 , and this embodiment does not limit the specific shape, size, number and distribution of the filter holes.
[0071] In a specific embodiment, Figure 4 As shown, along the axial direction of the filter screen 2 toward the direction away from the bottom plate 21, the inner diameter of the reinforcing wall 22 gradually increases.
[0072] In this embodiment, the reinforcing wall 22 is inclined with a width at the top and a narrowness at the bottom, which reduces sanitary dead corners and facilitates cleaning by users. On this basis, the inclination angle of the reinforcing wall 22 can be the same as the inclination angle of the inner wall of the bracket 1, that is, the outer wall of the reinforcing wall 22 can fit with the inner wall of the bracket 1 to increase the connection area between the filter 2 and the bracket 1, thereby improving the connection stability between the two. In addition, the outer wall of the reinforcing wall 22 fits with the inner wall of the bracket 1, which is also conducive to improving the sealing performance between the filter 2 and the bracket 1, and preventing liquid from flowing out from between the reinforcing wall 22 and the bracket 1.
[0073] In a specific embodiment, Figure 1 and Figure 2 As shown, the filtering device further comprises a base 3 , the base 3 has a second accommodating cavity 30 , and the bracket 1 is detachably installed in the second accommodating cavity 30 .
[0074] In this embodiment, the base 3 is used for assembly and disassembly with the coffee machine body. A collecting port is provided at the bottom of the base 3, which connects the second accommodating chamber 30 with the outside. When the bracket 1 is installed in the second accommodating chamber 30, the extraction liquid flowing out of the through hole of the bracket 1 can flow to the outside through the collecting port for the user to drink.
[0075] In addition, if Figure 1 and Figure 2 As shown, the filtering device further comprises a handle 4 fixedly connected to the base 3, and the user can move the base 3 or disassemble and assemble the base 3 with the coffee machine body by holding the handle 4.
[0076] In a specific embodiment, Figure 7 As shown, the base 3 is provided with a lap portion 31, and the bracket 1 is also provided with a flange 13, and a receiving groove 14 is formed between the flange 13 and the outer wall of the bracket 1, and the receiving groove 14 is used to limit the radial X movement of the lap portion 31 along the bracket 1 when the flange 13 overlaps the lap portion 31.
[0077] In this embodiment, Figure 5 As shown, the flange 13 is bent outward to form the accommodating groove 14. When the bracket 1 is installed in the second accommodating cavity 30, the flange 13 can overlap the overlapping portion 31. At this time, at least a portion of the overlapping portion 31 is located in the accommodating groove 14. The side wall of the accommodating groove 14 is used to limit the radial X movement of the overlapping portion 31 along the bracket 1. Similarly, the overlapping portion 31 is also used to limit the radial X movement of the flange 13 along the bracket 1. Therefore, the above structure is conducive to improving the installation stability of the bracket 1 and the base 3.
[0078] In a specific embodiment, Figure 7 As shown, the outer wall of the bracket 1 is provided with a convex rib 15 , and the convex rib 15 abuts against the inner wall of the base 3 .
[0079] In this embodiment, along the radial direction X of the bracket 1, the convex rib 15 protrudes toward the direction close to the inner wall of the base 3, and can abut against the inner wall of the base 3, thereby increasing the connection area between the bracket 1 and the base 3, preventing the bracket 1 from shaking along its own radial direction X, and also reducing the possibility of the bracket 1 rotating relative to the base 3, which is conducive to improving the installation stability of the bracket 1. In addition, during the disassembly and assembly process of the bracket 1, the convex rib 15 is used for frictional contact with the inner wall of the base 3, and the contact area between the two is small, which reduces the friction resistance, and is conducive to improving the convenience of disassembly and assembly of the bracket 1.
[0080] Among them, the convex rib 15 can be arranged in a whole ring along the circumference of the bracket 1, or it can be arranged in a plurality of split structures at intervals along the circumference of the bracket 1. The specific number can be 3, 4, 5, 6 or more, and this application does not impose any restrictions on this.
[0081] An embodiment of the present application also provides a coffee machine, comprising a main body and the filter device described in the above embodiments, wherein the filter device is detachably mounted on the main body. Since the filter device has the above technical effects, the coffee machine including the filter device should also have corresponding technical effects, which will not be repeated here.
[0082] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
