Description

Technical Field

[0001] This utility model belongs to the field of coffee machine technology, and in particular relates to a powder receiving bracket and a coffee machine. Background Technology

[0002] The coffee grinder's feed holder is used to support the feed portafilter, allowing the ground coffee to fall smoothly into the feed funnel. Currently, most feed holders are of fixed height, only compatible with specific portafilter sizes. This makes them unsuitable for different brands, models, and funnel heights, leading to misalignment during feed and causing spillage or leakage, thus affecting the coffee's performance.

[0003] Some coffee grinders have height-adjustable powder dispensers. A common height adjustment structure is a sliding groove with screw locking. For example, Chinese patent CN221430898U discloses a quantitative powder dispensing device for a coffee grinder. This device includes a fixed bracket 2 and a clamping component 3 movably mounted on the fixed bracket 2. The clamping component 3 can move on the fixed bracket 2 to accommodate different sized powder dispensers 4. The clamping component 3 is positioned by loosening the fixing screw, manually sliding it up and down, and then tightening it again. This structure has certain problems in practical use. For example, the adjustment steps are cumbersome, requiring two hands, resulting in low efficiency and a lack of good tactile feedback, leading to a poor user experience. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the purpose of this utility model embodiment is to provide a powder receiving stand and a coffee machine.

[0055] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0056] This embodiment of the invention provides a coffee powder receiving holder for use on a coffee machine. The holder is located below the coffee grinder and is used to hold the coffee powder funnel 4. Coffee powder ground by the grinder falls onto the receiving holder.

[0057] like Figure 1 As shown, the powder receiving bracket in this embodiment includes at least a first frame 1, a second frame 2, and a drive mechanism 3.

[0058] The first frame 1 is fixed to the coffee machine and is used to support the lower part of the coffee powder funnel 4. The second frame 2 is connected to the first frame 1 and is used to press down the upper part of the coffee powder funnel 4, and cooperates with the first frame 1 to fix the coffee powder funnel 4.

[0059] In this embodiment, the lower part of the powder receiving funnel 4 refers to the lower outer part of the funnel portion. Correspondingly, the upper part of the powder receiving funnel 4 refers to the open end of the funnel portion. It can be understood that the powder receiving funnel 4 is locked by the upper and lower clamping of the first frame 1 and the second frame 2.

[0060] The height between the first frame 1 and the second support is different for powder receiving funnels 4 of different heights. The drive mechanism 3 is located on the first frame 1. The drive mechanism 3 includes a knob 30 and a transmission mechanism connecting the knob 30 and the second frame 2. Rotating the knob 30 can drive the second frame 2 to rise or fall relative to the first frame 1 through the transmission mechanism, thereby adapting to powder receiving funnels 4 of different heights.

[0061] For example, such as Figure 7 and Figure 8As shown, when it is necessary to replace the powder receiving funnel 4, the knob 30 can be turned clockwise or counterclockwise, and then the transmission mechanism will drive the second frame 2 to rise relative to the first frame 1. Then the powder receiving funnel is placed on the first frame 1. Finally, the knob 30 is turned in the opposite direction, and the transmission mechanism will drive the second frame 2 to fall relative to the first frame 1, thereby clamping the powder receiving funnel 4.

[0062] In this embodiment, the powder receiving bracket has a drive mechanism 3 on the first frame 1. The drive mechanism 3 includes a knob 30 and a transmission mechanism. When the user wants to change the powder receiving funnel 4 of different heights, the user can rotate the knob 30 to adjust the height between the second frame 2 and the first frame 1 to accommodate powder receiving funnels 4 of different heights. This structure can be implemented with only one hand, which is convenient to operate, simplifies the operation steps, and improves the user experience.

[0063] like Figure 4 and Figure 5 As shown, in some embodiments, the second frame 2 may be provided with a transmission rack 23. The length direction of the transmission rack 23 is consistent with the lifting direction of the second frame 2.

[0064] The transmission mechanism may include a driving gear 31 and a driven gear set 32. The knob 30 is connected to the driving gear 31, and the rotation of the knob 30 can drive the driving gear 31 to rotate synchronously.

[0065] The driven gear set 32 ​​meshes with the driving gear 31 and the transmission rack 23 respectively. The rotation of the driving gear 31 drives the driven gear set 32 ​​to rotate through its meshing with the driven gear set 32. Simultaneously, the rotation of the driven gear set 32 ​​causes the transmission rack 23 to move relative to the driven gear set 32, thereby achieving the lifting and lowering of the second frame 2 relative to the first frame 1. The transmission mechanism in this embodiment has a simple structure and high transmission accuracy.

[0066] In this embodiment, the driving gear 31 and the driven gear set 32 ​​can be respectively mounted on the first frame 1 via the rotating shaft 33.

[0067] like Figure 5 and Figure 6 As shown, in some embodiments, the powder receiving bracket may further include a locking mechanism. This locking mechanism may include multiple positioning slots 37, positioning pins 34, and elastic elements 35.

[0068] Multiple positioning grooves 37 are respectively provided on the end face of one of the driven gears of the driven gear set 32, and are distributed in a circle around the rotation center of the corresponding driven gear.

[0069] The positioning pin 34 can be provided on the first frame 1 for extending into one of the positioning grooves 37. The elastic member 35 connects the positioning pin 34 and the first frame 1 and applies an elastic force to the positioning pin 34 to extend it into the positioning groove 37.

[0070] When the driven gear set 32 ​​rotates, it pushes against the locating pin 34, causing it to move out of the locating groove 37 and press against the elastic element 35. Whenever the driven gear set 32 ​​rotates a certain angle, the locating pin 34 will re-insert into another locating groove 37.

[0071] After the height of the second frame 2 relative to the first frame 1 is adjusted, the positioning pin 34 will be inserted into the positioning groove 37, thereby applying a force to the driven gear set 32 ​​to limit its transmission, ensuring that the second frame 2 will not float up or down.

[0072] In this embodiment, the positioning groove 37 can be provided on one or more driven gears in the driven gear set 32. When multiple driven gears are provided with multiple positioning grooves 37 respectively, each driven gear provided with a positioning groove 37 can correspond to a positioning pin 34.

[0073] The number of positioning slots 37 is not specifically limited. The number of positioning slots 37 can be the same as the number of teeth of the corresponding driven gear. Each time the driven gear rotates one tooth, the position of the positioning pin 34 inserted into the positioning slot 37 changes once.

[0074] In some embodiments, the axis of the locating pin 34 may be parallel to the axis of the driven gear. This can be understood as the locating pin 34 being perpendicular to the end face of the driven gear. The end of the locating pin 34 is used to insert into the locating groove 37. The end of the locating pin 34 may be spherical, and the shape of the locating groove 37 is adapted to the shape of the end of the locating pin 34. This structure ensures that the locating pin 34 can smoothly move out of the current locating groove 37 during the rotation of the driven gear.

[0075] In some embodiments, the elastic element 35 may be a spring or other elastic material. The number of elastic elements 35 is not specifically limited.

[0076] In some embodiments, the number of transmission racks 23 can be two or more. Each transmission rack 23 meshes with a driven gear, and the stability of the lifting and lowering of the second frame 2 can be ensured by the cooperation of multiple pairs of transmission racks 23 and driven gears.

[0077] For example, such as Figure 4 As shown, when there are two transmission racks 23, the two transmission racks 23 can be located on both sides of the drive gear 31.

[0078] The driven gear set 32 ​​may include a first driven gear and a second driven gear. The first driven gear meshes with the driving gear 31 and one of the transmission racks 23, respectively, and the second driven gear meshes with the driving gear 31 and the other transmission rack 23, respectively.

[0079] like Figure 2 and Figure 3 As shown, in some embodiments, the first frame 1 may include a first main body 11 and a first mating part 13 disposed on the first main body 11.

[0080] The first main body 11 can be directly fixed to the coffee machine and located below the grinder outlet. For example, it can be fixed to the outer casing or frame of the coffee machine.

[0081] The first mating part 13 can be located on the first side of the first main body 11. The first mating part 13 is provided with a slot 12, and the lower part of the powder receiving funnel 4 can be inserted into the slot 12 to realize the support of the first frame 1 for the powder receiving funnel 4. Here, the first side of the first main body 11 can be understood as the side facing the user.

[0082] The transmission mechanism can be located on the second side of the second mating part 21. The first and second sides are opposite to each other. This structure protects the transmission mechanism.

[0083] For example, such as Figure 2 As shown, the first mating part 13 can be located on the upper part of the first main body part 11 and extend towards the user. The slot 12 on the first mating part 13 can extend to the end facing the user. The powder receiving funnel 4 can be placed horizontally on the first mating part 13.

[0084] like Figure 1 and Figure 4 As shown, in some embodiments, the second frame 2 may include a second main body 20 and a second mating part 21 located on the second main body 20.

[0085] The second mating part 21 is used to press the periphery of the funnel opening of the coffee powder receiving funnel 4. The shape of the second mating part 21 can be adapted to the shape of the funnel opening, thereby avoiding affecting the coffee powder falling into the coffee powder receiving funnel 4.

[0086] The second mating part 21 can be located above the first mating part 13, and the second mating part 21 is opposite to the first mating part 13. The first mating part 13 is used to support the powder receiving funnel 4, and the second mating part 21 is used to press the powder receiving funnel 4. The powder receiving funnel 4 can be fixed by the cooperation of the first mating part 13 and the second mating part 21.

[0087] In this embodiment, the first main body 11 can be integrated with the first mating part 13, and the second main body 20 can be integrated with the second mating part 21, thereby facilitating the processing of both.

[0088] Alternatively, the first main body 11 and the first mating part 13, and the second main body 20 and the second mating part 21 can be two independent parts connected together by a corresponding connection structure.

[0089] In this embodiment, the shapes of the first main body 11 and the second main body are not specifically limited, and the shape of the first main body 11 can be adapted to the part fixed on the coffee machine.

[0090] The second main body 20 can be slidably connected to the first main body 11, and the second main body 20 can slide relative to the first main body 11 in the vertical direction, thereby realizing the lifting and lowering of the second frame 2 relative to the first frame 1.

[0091] For example, such as Figure 3 As shown, a guide groove 38 may be provided on the first main body 11, and the extension direction of the guide groove 38 is consistent with the movement direction of the second frame 2.

[0092] A guide bar 22 that mates with the guide groove 38 may be provided on the second main body 20. During the process of the second main body 20 rising and falling relative to the first main body 11, the guide bar 22 is always located within the guide groove 38. Through the sliding engagement between the guide bar 22 and the guide groove 38, the rising and falling of the second main body 20 can be guided.

[0093] Of course, in some other embodiments, the guide groove 38 may be provided on the second main body 20, and the guide strip 22 may be provided on the first main body 11.

[0094] In this embodiment, the position of the guide groove 38 on the first main body 11 is not specifically limited. The guide groove 38 may be provided on the second side of the first main body 11. There may be two sets of guide grooves 38, and the two sets of guide grooves 38 may be located on both sides of the drive gear 31.

[0095] In some embodiments, the first main body 11 may be provided with a knob hole that can pass through the first side and the second side of the first main body 11.

[0096] The rotating shaft 33 for fixing the drive gear 31 can be located in the knob hole. The knob 30 can be located on the first side of the first main body 11 and connected to the rotating shaft 33 for fixing the drive gear 31. Rotating the knob 30 can drive the rotating shaft 33 to rotate synchronously. The knob 30 is set to face the user directly for easy operation.

[0097] like Figure 2 and Figure 3 As shown, in some embodiments, the second side of the first main body 11 may be provided with a cavity (not shown in the figure) and a rear cover 36 for sealing the cavity.

[0098] The transmission mechanism can be embedded in the cavity, and the entire transmission mechanism can be sealed in the cavity by the rear cover 36.

[0099] The side of the second main body 20 can extend into the cavity, and the two driven gears in the driven gear set 32 ​​can extend from the side of the second main body 20 to mesh with the transmission rack 23. This structure protects the transmission mechanism without affecting its transmission.

[0100] This utility model embodiment also provides a coffee machine, which includes a powder receiving bracket as described in any of the above embodiments.

[0101] The powder receiving bracket can be fixed to the electronic scale or the frame of the coffee machine. When the powder receiving bracket is fixed to the electronic scale of the coffee machine, the powder funnel 4 can be weighed using the electronic scale.

[0102] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
