It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present invention.

[0037] As Figures 1 to 4 shown, this embodiment provides a coffee grinder configured with a bracket lifting device, including:

[0038] Coffee machine frame 1;

[0039] A bracket lifting device, arranged on the coffee machine frame 1, the bracket lifting device includes a motor 11 and a transmission assembly, and the output shaft of the motor 11 is connected to the input end of the transmission assembly; and,

[0040] A capsule box bracket 6, arranged on the coffee machine frame 1 and connected to the output end of the transmission assembly, and the motor 11 drives the capsule box bracket 6 to move up and down along the coffee machine frame 1 through the transmission assembly. Specifically, the capsule box is placed on the capsule box bracket 6, and when the capsule box bracket 6 moves up and down, it synchronously drives the capsule box to move.

[0041] In this embodiment, in order to optimize the structural layout inside the coffee machine frame 1, this embodiment sets the transmission assembly to include a lead screw 12 connected to the output shaft of the motor 11, a nut seat 3 assembly threadedly connected to the lead screw 12, the nut seat 3 assembly is connected to the capsule box bracket 6, and the coffee machine frame 1 is provided with a first guiding channel 5 for the nut seat 3 assembly to slide up and down along the coffee machine frame 1. Specifically, the capsule box bracket 6 can be arranged on the front side of the front side wall 15 of the coffee machine frame 1, the first guiding channel 5 is arranged on the front side wall 15, the motor 11 is located at the upper end of the lead screw 12, and bearings 13 are arranged between the upper and lower ends of the lead screw 12 and the coffee machine frame 1. The motor 11 can be specifically fixed inside the coffee machine frame 1 through a motor bracket 111. When the motor 11 starts, it drives the lead screw 12 to rotate. Due to the effect of the first guiding channel 5, the nut seat 3 assembly will rise or fall along the lead screw 12.

[0042] Among them, as Figure 1 and Figure 3 shown, the nut seat 3 assembly includes a nut seat 3 threadedly connected to the lead screw 12 and a connecting frame 4 fixedly connected to the nut seat 3. One end of the connecting frame 4 is fixedly connected to the nut seat 3, and a sliding member 41 that slides up and down along the first guiding channel 5 is provided between the other end and the capsule box bracket 6. The rear end of the sliding member 41 is connected to the connecting frame 4, and the front end of the sliding member 41 passes through the first guiding channel 5 and is connected to the capsule box bracket 6. Specifically, the connecting frame 4 is arranged inside the coffee machine frame 1 in the left-right direction, and is bent on the left side to form a connecting portion for connecting with the sliding member 41.

[0043] Among them, the bracket can be arranged to include a bracket body and a bracket connecting portion 61 provided between the bracket body and the sliding member 41, and the connecting frame 4, the sliding member 41 and the bracket connecting portion 61 can be integrally formed.

[0044] As a specific implementation manner, as Figure 1 and Figure 3 shown, the connecting frame 4 is located below the nut seat 3, and one end of the connecting frame 4 close to the nut seat 3 is slidably sleeved outside the lead screw 12. One end of the connecting frame 4 close to the nut seat 3 can be specifically fixedly connected to the nut seat 3 by means of screws or nut bolts.

[0045] In this embodiment, as Figures 1 to 4 shown, in order to effectively prevent coffee powder from entering the coffee machine frame 1 from the first guiding channel 5, a sealing member 2 is provided in the first guiding channel 5 in this embodiment, and a second channel 21 for the sliding member 41 to slide up and down through is provided on the sealing member 2. The function of the sealing member 2 is to seal the first guiding channel 5, so that the sliding member 41 slides up and down along the second channel 21, and the generated gap is smaller.

[0046] Among them, the material of the sealing member 2 is preferably foamed silica gel. When the sliding member 41 slides up and down along the second channel 21, the foamed silica gel can automatically close together at the parts not cooperating with the sliding member 41, further reducing dust and the like entering the coffee machine frame 1 from the second channel 21. For example, when the sliding member 41 slides downward, the foamed silica gel seals the second channel 21 above and below the sliding member 41. When the sliding member 41 continues to slide downward, it continuously drives the sealing members 2 on the left and right sides below to open, while the parts that have passed above continue to be sealed together.

[0047] As Figure 5As shown, in order to further reduce the gap between the slider 41 and the seal 2, in this embodiment, the longitudinal section of the part where the slider 41 cooperates with the second channel 21 is such that the diameters at the upper and lower ends are small and the diameter in the middle is large. Preferably, the left and right sides of this part protrude towards the left and right sides respectively and are arc-shaped, so that the foamed silica gel on the left and right sides of the slider 41 can better fit on the left and right sides of the slider 41, and the gap between the two is smaller.

[0048] In this embodiment, as Figure 1 , Figure 4 and Figure 6 shown, in order to better fix the seal 2 on the coffee machine frame 1, in this embodiment, two clamping grooves are provided on the coffee machine frame 1 on the left and right sides of the seal 2, and the left and right sides of the seal 2 are respectively located in the two clamping grooves. Specifically, the front side of the coffee machine frame 1 is provided with a front side wall 15, and the first guiding channel 5 is arranged on the front side wall 15. The rear side of the front side wall 15 of the coffee machine frame 1 is provided with a fixing plate 14 fixedly connected to the front side wall 15 of the coffee machine frame 1. The fixing plate 14 and the front side wall 15 of the coffee machine frame 1 form the two clamping grooves, and the fixing plate 14 is provided with a third guiding channel 142 that slidably cooperates with the slider 41 up and down. Both the first guiding channel 5 and the second channel 21 are guiding holes, and the middle part of the seal 2 is located in the first guiding channel 5. Two rearward baffles can be arranged on the rear side of the front side wall 15, and two clamping grooves are formed between the two baffles and the fixing plate 14, clamping the left and right sides of the seal 2 respectively to fix the seal 2.

[0049] Among them, as Figure 1 and Figure 4 shown, the fixing plate 14 can be fixedly connected to the front side wall 15 by screws. As a specific structure, a fixing plate mounting part 141 is provided on each of the left and right sides of the upper, middle, and lower parts of the fixing plate 14, and corresponding screw mounting seats are arranged on the front side wall 15 of the coffee machine frame 1, and six screws are screwed into the fixing plate mounting part 141 and the screw mounting seats one by one.

[0050] In this embodiment, in order to facilitate the clamping groove to clamp the seal 2, the shape of the seal 2 is set to be thick in the middle and thin on the left and right sides. The thick part in the middle cooperates with the slider 41, which can achieve a better sealing effect.

[0051] Principle of operation description:

[0052] When the motor 11 drives the lead screw 12 to rotate forward, the nut seat 3 rises along the lead screw 12. At the same time, the nut seat 3 drives the capsule box bracket 6 to rise through the connecting frame 4 and the sliding member 41, so that the capsule box on the capsule box bracket 6 is docked with the powder receiving port. When the motor 11 rotates in the reverse direction, the nut seat 3 descends along the lead screw 12. At the same time, the nut seat 3 drives the capsule box bracket 6 to descend through the connecting frame 4 and the sliding member 41, so that the capsule box on the capsule box bracket 6 is separated from the powder receiving port and returns to the initial position.

[0053] The present utility model is not limited to the above optional embodiments. On the premise of not conflicting with each other, various schemes can be arbitrarily combined; anyone can obtain other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present utility model, they all fall within the protection scope of the present utility model.
