[0054] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly. In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0056] The embodiment of the present application provides a powder distribution device for a coffee machine. Figures 8 to 11 As shown, the coffee machine includes at least a bean grinding device 5 and a funnel assembly 6. The bean grinding device 5 has a powder outlet channel 51. The bean grinding device 5 is used to grind coffee powder 4, and the ground coffee powder 4 can be discharged through the powder outlet channel 51. The funnel assembly 6 can hold the coffee powder 4, and then pouring hot water into the funnel assembly 6 can prepare coffee liquid.

[0057] like Figure 1 and Figure 2 As shown, the powder distribution device of this embodiment at least includes a funnel bracket 1, a driving component 2 and a scattering component 3.

[0058] The funnel bracket 1 is used to connect the bean grinding device 5 and the funnel assembly 6. The funnel bracket 1 has a rotating part 11. The rotating part 11 has a powder leakage channel 12. The powder leakage channel 12 can connect the powder outlet channel 51 and the funnel assembly 6. The coffee powder 4 in the powder outlet channel 51 can enter the funnel assembly 6 through the powder leakage channel 12.

[0059] The driving component 2 is used to drive the rotating member 11 to rotate. The breaking member 3 is connected to the rotating member 11 and can extend into the funnel assembly 6. Moreover, the breaking member 3 can rotate synchronously with the rotating member 11 to break up the coffee powder 4 that falls into the funnel assembly 6.

[0060] The funnel support 1 of the coffee distribution device of this embodiment is used to connect the bean grinding device 5 and the funnel assembly 6. The funnel support 1 is provided with a rotating member 11. The loosening needle 31 is mounted on the rotating member 11 and can rotate with the rotating member 11 to loosen the coffee powder 4 that falls into the funnel assembly 6. In this way, after the bean grinding device 5 feeds the ground coffee powder 4 into the funnel assembly 6, the rotating member 11 is rotated to loosen the convex coffee powder 4 in the funnel assembly 6 into a flat state. This structure not only ensures more uniform coffee extraction, but also reduces the user's operation steps, thereby improving the user experience.

[0061] like Figure 3 and Figure 4 As shown, in some embodiments, the scattering piece 3 may include a plurality of scattering needles 31 , and the plurality of scattering needles 31 are arranged at intervals along the circumference of the powder leakage channel 12 .

[0062] The scattering needles 31 may include a connecting portion 310 and a scattering portion 311 connected to the connecting portion 310. The connecting portions 310 of the scattering portions 31 are respectively located at the periphery of the powder leakage channel 12 and are used to connect to the rotating member 11 to connect the scattering needles 31 and the rotating member 11.

[0063] The disintegrating portion 311 includes at least a first rod 3111 and a second rod 3112. The first rod 3111 connects the second rod 3112 and the connecting portion 310. The first rod 3111 extends into the powder leakage channel 12, and the second rod 3112 extends along the axial direction of the powder leakage channel 12 and is used to extend into the funnel assembly 6.

[0064] When the rotating member 11 rotates, the multiple breaking needles 31 can be driven to rotate synchronously, thereby achieving uniform stirring of the coffee powder 4 in the funnel assembly 6.

[0065] like Figure 2 and Figure 4 As shown, in some embodiments, a plurality of first matching portions 112 are provided at intervals along the circumference of the powder leakage channel 12 at one end of the rotating member 11 facing the funnel assembly 6 .

[0066] The connecting portion 310 is provided with a second mating portion 312. The first mating portion 112 and the second mating portion 312 cooperate to connect the rotating member 11 and the loosening needle 31. Positioning the first mating portion 112 on the end of the rotating member 11 facing the funnel assembly 6 facilitates its connection with the second mating portion 312 and reduces the length of the second rod 3112.

[0067] The structures of the first matching portion 112 and the second matching portion 312 are not specifically limited in this embodiment.

[0068] For example, Figure 2 and Figure 4 As shown, the first matching portion 112 can be a connecting post, and the second connecting portion 310 can be a connecting sleeve. The connecting post can be inserted into the connecting sleeve to connect the rotating member 11 and the breaking up needle 31. This embodiment is described by taking the first matching portion 112 as the connecting post and the second matching portion 312 as the connecting sleeve as an example.

[0069] Alternatively, the first matching portion 112 may be a bolt hole, and the second matching portion 312 may be a stud. The stud is screwed into the bolt hole to connect the rotating member 11 and the scattering needle 31 .

[0070] like Figure 3 and Figure 4 As shown, in some embodiments, the structure of the connecting portion 310 can be a rod-shaped member, and the second matching portion 312 can be located in the middle of the connecting portion 310 .

[0071] The number of the breaking up parts 311 can be two, wherein the first rod body 3111 of one breaking up part 311 is connected to the first end of the connecting part 310, and the first rod body 3111 of the other breaking up part 311 is connected to the second end of the connecting part 310. That is, the two breaking up parts 311 are located at opposite ends of the connecting part 310.

[0072] In some embodiments, the connecting portion 310 and the breaking-up portion 311 may be an integral structure, and the second matching portion 312 may be formed by bending the connecting portion 310 .

[0073] For example, Figure 3 and Figure 4 As shown, the scattering needle 31 can be formed by bending a flexible metal wire, and the scattering portion 311 can be bent into an L-shape. When the second matching portion 312 is a connecting sleeve, the connecting portion 310 can be formed into a connecting sleeve by spiral bending. This structure facilitates the processing of the scattering needle 31.

[0074] In some embodiments, as Figures 3 to 6 As shown, when there are multiple scattering needles 31 and each scattering needle 32 includes two scattering parts 311, the length of the first rod body 3111 of one scattering part 311 of each scattering needle 31 is greater than the length of the first rod body 3111 of the other scattering part 311.

[0075] Moreover, the angle between the first rod bodies 3111 of the two scattering parts 311 of each scattering needle 32 can be an acute angle. Multiple scattering needles 31 are arranged at circumferential intervals along the powder leakage channel 12. The length of the first rod bodies 3111 and the length of the second rod bodies 3112 of two adjacent scattering needles 31 can be different. This layout can stir the coffee 4 in the funnel assembly 6 in all directions.

[0076] like Figure 2 As shown, in some embodiments, the funnel support 1 may have a mounting channel 18 for the rotating member 11. The mounting channel 18 passes through the upper and lower ends of the funnel support 1, and the powder leakage channel 12 on the rotating member 11 is coaxial with the mounting channel 18. That is, the top open end of the powder leakage channel 12 is opposite to the top open end of the mounting channel 18, and the bottom open end of the powder leakage channel 12 is opposite to the bottom open end of the mounting channel 18.

[0077] A plurality of avoidance grooves 17 are provided at intervals on the outer peripheral wall of one end of the funnel bracket 1 opposite to the funnel assembly 6 , and each avoidance groove 17 extends along the circumference of the installation channel 18 .

[0078] Furthermore, a plurality of protruding buckles 61 are provided at intervals on the outer periphery of the open end of the funnel assembly 6. The plurality of protruding buckles 61 correspond one-to-one with the plurality of avoidance grooves 17, and the plurality of protrusions can be snapped into the plurality of avoidance grooves 17 one-to-one, thereby connecting the funnel bracket 1 and the funnel assembly 6. This structure facilitates the installation and removal of the funnel assembly 6.

[0079] For example, Figure 2 As shown, the bottom sidewall of the funnel bracket 1 may have a notch extending through the avoidance groove 17. When installing the funnel assembly 6, the funnel assembly 6 may be placed below the funnel bracket 1, with the raised buckle portion 61 on the funnel assembly 6 aligned with the notch on the funnel bracket 1. The funnel bracket 1 may then be moved upward through the notch and then rotated counterclockwise, causing the raised buckle portion 61 to engage with the avoidance groove 17, thereby securing the funnel assembly 6 to the funnel bracket 1.

[0080] Furthermore, in some embodiments, a frame cover 15 is connected above the funnel bracket 1 , and a powder leakage hole coaxial with the installation channel 18 can be provided on the frame cover 15 , and the frame cover 15 can be used to cover the rotating part 11 in the installation channel 18 .

[0081] like Figure 2 As shown, in some embodiments, the driving component 2 may be provided on the funnel support 1 , and the driving component 2 may include a driving motor 21 and a gear 22 connected to the driving motor 21 .

[0082] The rotating member 11 may be a columnar member, and the outer peripheral wall of the rotating member 11 may have a gear ring engaged with the gear 22. That is, the structure of the rotating member 11 may be a gear member, and the rotating member 11 has a central hole, which may form the powder leakage channel 12.

[0083] The driving motor 21 can rotate through the driving gear 22 to drive the rotating member 11 to rotate synchronously. This structure is simple and easy to implement.

[0084] like Figure 2 As shown, in the case where the rotating member 11 is a gear member, the top edge and the bottom edge of the central hole of the rotating member 11 protrude outward to form an annular platform 111.

[0085] In some embodiments, the funnel bracket 1 is also provided with two bearings 13 respectively clamped in the installation channel 18. The two bearings 13 are located on opposite sides of the rotating part 11 and are respectively clamped on the annular platforms 111 on the upper and lower sides of the rotating part 11. The rotating part 11 can be supported by the two bearings 13 to rotate in the installation channel 18.

[0086] Furthermore, a wool felt ring 14 is provided above the top bearing 13 and below the bottom bearing 13 in the funnel bracket 1, respectively, which can prevent coffee powder 4 from entering the bearing 13 and affecting its normal use.

[0087] For example, Figure 6 and Figure 7 As shown, in some embodiments, the powder distributing device may further include a switch assembly 16 , wherein the switch assembly 16 may include a switch frame 161 , a switch member 162 and a switch rod 163 .

[0088] The switch frame 161 can be mounted on the funnel support 1, and the switch member 162 and the switch rod 163 can be respectively mounted on the switch frame 161. The switch member 162 can be mounted on and electrically connected to the control circuit of the drive motor 21. When the switch member 162 is not triggered, the drive motor 21 is powered off and cannot operate. When the switch member 162 is triggered, the drive motor 21 is powered on and can operate normally.

[0089] One end of the switch rod 163 can be opposite to the switch member 162, and the other end can be used to resist the raised buckle 61 on the funnel assembly 6. When the raised buckle 61 of the funnel bracket 1 is screwed into the avoidance groove 17 on the funnel bracket 1, the raised buckle 61 can push the switch member 162 to move relative to the switch frame 161 to trigger the switch member 162, so that the drive motor 21 is powered on and can work normally.

[0090] In some embodiments, the switch rod 163 can be elastically connected to the switch frame 161 via an elastic member 164. When the switch member 162 is pushed against the raised catch 61 and moves in a first direction to trigger the switch member 162, the elastic member 164 is compressed. After the raised catch 61 separates from the switch member 162, the elastic action of the elastic member 164 causes the switch member 162 to move in a second direction to separate from the switch member 162, thereby deactivating the switch member 162. This switch assembly 16 prevents the disassembly member 3 from rotating before the funnel assembly 6 is installed, thereby improving the safety of the device.

[0091] like Figures 8 to 11 As shown, an embodiment of the present application further provides a coffee machine, which may mainly include a bean grinding device 5, a funnel assembly 6 and a powder distribution device as described in any of the above embodiments.

[0092] The bean grinding device 5 can be used to grind coffee beans into coffee powder 4. The bean grinding device 5 has a powder outlet channel 51, and the ground coffee powder 4 can be discharged through the powder outlet channel 51. The funnel assembly 6 is used to receive the coffee powder 4.

[0093] In some embodiments, the coffee machine may further include a machine body 8, the bean grinding device 5 and the powder distribution device may be respectively installed on the machine body 8, the top of the bean grinding device 5 may be connected to a coffee bean box 7, the coffee bean box 7 may be used to hold coffee beans, and the held coffee beans may be fed into the bean grinding device 5 for grinding.

[0094] The above description is intended to be illustrative rather than restrictive, and those skilled in the art may make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present disclosure. Furthermore, the above examples (or one or more of them) may be used in combination with each other, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations.
