The support frame 4 includes a control part 42 and a support part 41. The support part 41 can be stored in the storage slots 33 so that the filter 3 can be stored in the cup body 1. The support frame 4 can move in the storage slots 33 and allow the support part 41 to pass through the side of the filter 3 so that the support part 41 can abut against the end of the cup body 1. The filter 3 is provided with at least two support frames 4, and a driving component 5 is movably provided on the filter 3. The driving component 5 is provided with several driving parts 55. The driving parts 55 are respectively connected to the control parts 42 on each support frame 4, and can drive each support frame 4 to move relative to the filter 3. In this structure, the movement of each support frame 4 can be controlled by one driving component 5, which makes it convenient for the user to quickly control the opening and closing of each support frame 4, making it convenient for the user to use. In addition, in this structure, the support frame 4 can swing to the side of the filter 3. During use, the support frame 4 is not easy to swing freely into the storage slot 33 for storage, which avoids the support frame 4 being accidentally stored into the storage slot 33 during use and prevents the filter 3 from accidentally falling into the cup body 1.

[0048] In this embodiment, three hinge grooves 32 are evenly arranged on the outer circumference of the filter 3, and a support frame 4 is rotatably arranged in each hinge groove 32. The filter 3 is provided with a filter cavity 31. When the filter 3 is connected to the grinding device 2, the filter cavity 31 is located below the grinding device 2.

[0049] The driver 21 includes a housing 211, in which a drive motor 212 and a control switch 213 are disposed. The output end of the drive motor 212 is provided with a transmission hole 214, which is an irregularly shaped hole. The grinding head 22 includes a storage box 221, in which a storage cavity 224 is disposed. A grinding cavity 225 is disposed at the lower end of the storage cavity 224. A grinding component 223 is disposed in the grinding cavity 225. A transmission shaft 222 is disposed on the grinding component 223.

[0050] During the coffee bean grinding process, the driver 21 and the grinding head 22 are first disassembled relative to each other, and the coffee beans are placed in the storage chamber 224. The coffee beans will enter the grinding chamber 225 under the action of gravity. Then, the driver 21 and the grinding head 22 are connected relative to each other, and the support frame 4 is controlled to unfold to the side of the filter 3 through the drive component 5. The filter 3 is installed at the end of the cup body 1. The drive motor 212 can drive the grinding component 223 to rotate through the transmission hole 214 and the transmission shaft 222. The coffee powder crushed by the grinding component 223 can enter the filter chamber 31.

[0051] When brewing coffee, pour hot water into the filter chamber 31, and the filter 3 can filter the coffee powder.

[0052] The grinding head 22 and the driver 21 are common mechanisms in coffee machines. Therefore, although the present invention provides a brief description of the grinding head 22 and the driver 21, those skilled in the art can implement the technical solution of the present invention.

[0053] In this utility model, a protective shell 6 is detachably provided on the grinding device 2. When the grinding device 2 is connected to the protective shell 6, the driver 21 is housed in the protective shell 6. A cup lid 7 is detachably provided on the protective shell 6. The cup lid 7 can be detachably connected to the cup body 1, making it convenient for the user to drink the coffee in the cup body 1.

[0054] In this utility model, the support part 41 is preferably provided with a guide groove 43, which extends in the direction of movement of the drive part 55. The drive part 55 passes through the guide groove 43. During the movement of the support frame 4 controlled by the drive member 5, the drive part 55 moves along the guide groove 43. The guide groove 43, which cooperates with the drive part 55, is conducive to the stable installation of the support frame 4, reduces the swaying of the support frame 4 during use, and is also conducive to the stable support of the filter 3 by the support frame 4, making it convenient for users to use.

[0055] The support frame 4 or filter 3 is provided with a positioning groove 44. The drive part 55 is adapted to the positioning groove 44. The cooperation between the drive part 55 and the positioning groove 44 can fix the drive part 5 and the support frame 4 relative to the filter 3, and keep the support part 41 in the state of being stored in the storage groove 33, or keep the support part 41 in the state of being protruding from the side of the filter 3. Under the action of external force, the drive part 55 can disengage from the positioning groove 44, so that the support frame 4 can rotate relative to the filter 3. The setting of the positioning groove 44 is conducive to fixing the drive part 5 and the support frame 4 relative to the filter 3, and keeping the support frame 4 in the state of being stored in the storage groove 33 or in the state of being protruding from the side of the filter 3. It avoids the support frame 4 swinging freely during use, and makes it convenient for the user to store the filter 3 in the cup body 1, or to install the filter 3 at the mouth of the cup body 1, so as to facilitate the user's use.

[0056] In this embodiment, the support frame 4 is provided with two sets of positioning grooves 44, and the filter 3 is provided with two sets of positioning walls 331. When the drive unit 55 cooperates with the two sets of positioning grooves 44, the support frame 4 abuts against the two sets of positioning walls 331 respectively, and keeps the support frame 4 in the state of being stored in the storage groove 33 and in the state of being protruding from the side of the filter 3 respectively. The arrangement of the two sets of positioning grooves 44 and the two sets of positioning walls 331 makes it convenient for the support frame 4 to maintain both the storage box and unfolded states, which is convenient for users.

[0057] Preferably, the positioning groove 44 is located on the side of the guide groove 43. This structure facilitates the switching of the drive unit 55 between the two sets of positioning grooves 44, and avoids misalignment between the drive unit 55 and the positioning groove 44, which would affect the fixed installation of the support frame 4 and the filter 3.

[0058] The drive component 5 is provided with a limiting part 53, and the filter 3 is provided with a limiting groove 34 adapted to the limiting part 53. The limiting part 53 and the limiting groove 34 cooperate to limit the movement range of the drive component 5 and the filter 3, thereby facilitating the connection and cooperation between the drive component 5 and the control unit 42. The setting of the limiting part 53 and the limiting groove 34 is beneficial to limiting the movement range of the drive component 5, and makes it convenient for the user to quickly control the support leg to be stored in the storage groove 33 or to control the support leg to be passed out from the side of the filter 3 through the drive component 5, which is convenient for the user. Moreover, this structure can prevent the drive unit 55 from disengaging from the control unit 42 during use, which facilitates the drive control of the support component by the drive unit 5.

[0059] In this invention, the driving component 5 is provided with an elastic arm 532, and a limiting part 53 is provided on the elastic arm 532. The elastic arm 532 can drive the limiting part 53 to maintain a fit with the limiting groove 34, and keep the driving component 5 connected to the filter 3. The limiting part 53 is provided with a driving inclined surface 531. During the assembly of the driving component 5 and the filter 3, the filter 3 can abut against the driving inclined surface 531 and cause the limiting part 53 to move, so that the limiting part 53 and the limiting groove 34 can quickly fit together. The provision of the elastic arm 532 and the driving inclined surface 531 facilitates the assembly and fit of the driving component 5 and the filter 3, and facilitates the assembly and production of the coffee grinder.

[0060] The drive component 5 is sleeved on the outer periphery of the filter 3 and rotatably connected to the filter 3. It controls the relative rotation of the drive component 5 and the filter 3. The drive unit 55 can move relative to the control unit 42 on each support frame 4 and drive each support frame 4 to move. The rotatable drive component 5 is easy for the user to drive and control. Since the drive component 5 is sleeved on the outer periphery of the filter 3, it is easy for the drive component 5 to connect with each support frame 4. During use, the drive component 5 rotates horizontally and will not move under the action of gravity, thus avoiding the drive component 5 accidentally driving the support frame 4 to swing into the storage slot 33 during use.

[0061] The filter 3 described in this utility model has an annular hinge wall 35 on its outer periphery. The drive component 5 has a mounting hole 51 that matches the hinge wall 35. The filter 3 passes through the mounting hole 51, and the support frame 4 can be stored in the mounting hole 51. The side wall of the mounting hole 51 has a through groove 52, through which the support frame 4 can pass and swing to the outside of the drive component 5. In this structure, the support frame 4 is placed in the mounting hole 51, which is conducive to the concealment and storage of the support frame 4, avoids friction and bumping of the support frame 4 during the movement of the filter 3, avoids accidental damage to the support frame 4, and helps to extend the service life of the coffee grinder. The through groove 52 makes it easy for the support frame 4 to swing to the outside of the drive component 5, and the through groove 52 can reduce the up and down swing of the support frame 4 during use, which helps to improve the structural strength and stability of the support frame 4 installation. In this embodiment, the drive component 5 has three through grooves 52 corresponding to each support frame 4.

[0062] The filter 3 has a hinge groove 32 on its outer side, and the support frame 4 has a hinge rod 45 that is adapted to the hinge groove 32. The side wall of the mounting hole 51 extends to the end of the hinge groove 32 and prevents the hinge rod 45 from disengaging from the hinge groove 32. The hinge groove 32 on the outer side of the filter 3 facilitates the assembly of the support frame 4 and makes it convenient for the assembly and production of the coffee grinder.

[0063] In this utility model, the outer side of the driving component 5 is provided with anti-slip protrusions or anti-slip grooves 54. The driving component 5 and the filter 3 can be driven to rotate relative to each other through the anti-slip protrusions or anti-slip grooves 54. The anti-slip protrusions or anti-slip grooves 54 make it easy for the user to pick up the filter 3 and also make it easy for the user to control the rotation of the driving component 5, making it convenient for the user to use. In this embodiment, the outer side of the driving component 5 is provided with anti-slip grooves 54.

[0064] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
