Description

Technical Field

[0001] The present application relates to the technical field of beverage preparation, and particularly relates to a brewing device for a beverage preparation device and a beverage preparation device. Background Art

[0002] When a fully automatic coffee machine on the current market receives coffee powder, compresses the coffee powder, and brews coffee, the brewing chamber of the brewing cup first receives the coffee powder, the movable brewing head compresses the coffee powder in the brewing chamber, the water pump supplies water into the brewing chamber to complete coffee brewing, and then the movable brewing head returns to the initial position. This causes too much coffee residue to remain at the lower end of the movable brewing head. The remaining coffee residue will be pressed against the coffee powder in the brewing chamber again during the next brewing, thereby affecting the subsequent coffee brewing effect, and the remaining coffee residue has the risk of deterioration and is likely to cause food safety problems. For example, Chinese Patent No. CN105105636A discloses a structure of a movable coffee brewing head, including: a brewing head having a base, a connecting portion provided in the center above the base, and at least two sliders provided at the edge above the base, and the connecting portion is connected with a driving device; a brewing head bracket having an accommodating chamber, and at least two slideways corresponding to the sliders are provided in the chamber, and the slideways extend obliquely. When the driving device rotates the brewing head, the brewing head can move up and down in the brewing head bracket. It can be seen that the structure of the movable coffee brewing head does not clean the residue on it after compressing the coffee powder, and there is a problem that too much coffee residue remains at the lower end of the structure of the movable coffee brewing head.

[0025] An embodiment of the present application provides a brewing device for a beverage preparation device. As Figures 1 to 6 shown, the brewing device for the beverage preparation device includes a brewing support 1, a brewing head assembly 2, and a brewing cup assembly 3. A residue pushing structure 11 is provided on the brewing support 1. The brewing head assembly 2 includes a fixed brewing head 21 provided on the brewing support 1. The brewing cup assembly 3 includes a movable cup body 31 movably provided on the brewing support 1. The movable cup body 31 is located below the fixed brewing head 21, and the movable cup body 31 at least makes a powder pressing movement close to the fixed brewing head 21, and makes a residue pushing movement relatively close to the residue pushing structure 11 after the powder pressing movement. A powder residue channel 4 is provided on one side of the movable cup body 31, and a movable residue scraping piece 5 close to the powder residue channel 4 is provided on the upper side of the movable cup body 31. The upper end surface of the movable residue scraping piece 5 acts on the lower end of the fixed brewing head 21. When the movable cup body 31 makes a residue pushing movement, the movable residue scraping piece 5 scrapes the powder residue at the lower end of the fixed brewing head 21 into the powder residue channel 4.

[0026] The above-mentioned residue pushing structure 11 can be arranged close to the fixed brewing head 21. The residue pushing structure 11 can be understood as being fixedly arranged on the brewing support 1 and used to push the residue pile in the movable cup body 31 into the powder residue channel 4 when the movable cup body 31 makes a residue pushing movement. The residue pushing structure 11 can be configured as a plate shape, so as to push the residue pile in the movable cup body 31 into the powder residue channel 4 through the plate-shaped residue pushing structure 11.

[0027] Specifically, after the movable cup body 31 makes a powder pressing movement close to the fixed brewing head 21, the powdery food materials in the movable cup body 31 can be brewed. After brewing, a delicious beverage will be prepared. The powdery food materials in the movable cup body 31 will form a residue pile after brewing. Then the movable cup body 31 can move in the direction close to the residue pushing structure 11, so that the residue pushing structure 11 can push the residue pile in the movable cup body 31 into the powder residue channel 4.

[0028] The above-mentioned brewing device can adopt the method of rotating and pressing the powder. For example, after the movable cup body 31 makes a powder-pressing movement closer to the fixed brewing head 21, the fixed brewing head 21 can rotate relative to the movable cup body 31 to achieve rotating and pressing the powdery ingredients into the movable cup body 31.

[0029] The powder-pressing movement of the above-mentioned movable cup body 31 closer to the fixed brewing head 21 can be understood as a rising movement in the vertical direction. After brewing is completed, the movable cup body 31 can make a descending movement to move away from the fixed brewing head 21 and be located below the fixed brewing head 21, and then make a slag-pushing movement in the horizontal direction, so that the slag pile in the movable cup body 31 can be pushed by the slag-pushing structure 11 into the powder and slag channel 4.

[0030] A liftable push rod can be provided inside the above-mentioned movable cup body 31. Before brewing, the push rod is located at the bottom of the movable cup body 31 to receive the powdery ingredients. After brewing is completed, the push rod will move upward to push the slag pile formed after brewing to the upper open end of the movable cup body 31, so as to push the slag pile out of the movable cup body 31 via the slag-pushing structure 11.

[0031] As Figure 2 and Figure 4 shown, the above-mentioned movable slag-scraping member 5 can be located between the powder and slag channel 4 and the slag-pushing structure 11, so that the powder and slag scraped off by the movable slag-scraping member 5 and the slag pile scraped off by the slag-pushing structure 11 can both fall into the powder and slag channel 4 along with the slag-pushing movement of the movable cup body 31. Specifically, the upper part of the above-mentioned powder and slag channel 4 can be at least partially open to directly receive the powder and slag scraped off by the movable slag-scraping member 5 and the slag pile scraped off by the slag-pushing structure 11.

[0032] The above-mentioned movable slag-scraping member 5 can be constructed as an elastic member, so that when scraping the powder and slag at the lower end of the fixed brewing head 21, it can contact more with the lower end of the fixed brewing head 21 through deformation, so that the movable slag-scraping member 5 can exert a better cleaning force on the lower end of the fixed brewing head 21.

[0033] The above-mentioned movable slag-scraping member 5 can have a slag-scraping rod, and the slag-scraping rod can move along the lower end of the fixed brewing head 21 to clean the lower end of the fixed brewing head 21 comprehensively. A brush body can be provided on the side of the slag-scraping rod facing the lower end of the fixed brewing head 21 to achieve further cleaning through the brush body.

[0034] In this application, through the movable cup body 31 movably disposed on the brewing support 1, the powder residue channel 4 and the movable residue scraping member 5 disposed on the movable cup body 31, when the movable cup body 31 first approaches the fixed brewing head 21 to perform a powder pressing movement, after powder residue remains at the lower end of the fixed brewing head 21, the movable residue scraping member 5 can scrape the powder residue at the lower end of the fixed brewing head 21 into the powder residue channel 4 along with the slag pushing movement of the movable cup body 31. The above structure does not require additional movement structures to drive the movable residue scraping member 5. The movable residue scraping member 5 can fully scrape the powder residue remaining at the lower end of the fixed brewing head 21 as it moves with the movable cup body 31, making the structural design of the brewing device more reasonable, reducing the impact of the remaining powder residue on the subsequent preparation of beverages, achieving the purpose of preparing beverages with a better taste, and more effectively avoiding food safety problems caused by the deterioration of the remaining powder residue.

[0035] In some embodiments, as Figure 2 and Figure 3 shown, before the movable cup body 31 performs a slag pushing movement, the slag pushing structure 11 and the powder residue channel 4 are respectively located on opposite sides of the open end of the movable cup body 31, so that when the movable cup body 31 performs a slag pushing movement relatively closer to the slag pushing structure 11, the slag pushing structure 11 can push the slag pile at the open end of the movable cup body 31 into the powder residue channel 4.

[0036] In this way, the slag pushing structure 11 can push the slag pile at the open end of the continuously approaching movable cup body 31 into the powder residue channel 4, enabling the slag pile at the open end of the movable cup body 31 to be directly recycled through the powder residue channel 4, with a reasonable structural design.

[0037] The inlet of the above powder residue channel 4 can be connected to the movable cup body 31, and a slag receiving cup can be provided at the outlet of the powder residue channel 4 to collect the residue from the powder residue channel 4.

[0038] As Figure 2 and Figure 3 shown, Figure 2 and Figure 3 show the state before the movable cup body 31 performs a slag pushing movement. At this time, the slag pushing structure 11 and the powder residue channel 4 are respectively located on opposite sides of the open end of the movable cup body 31. As Figure 4 and Figure 5 shown, Figure 4 and Figure 5 show the state after the movable cup body 31 performs a slag pushing movement. After the movable cup body 31 performs a slag pushing movement, the slag pushing structure 11 and the powder residue channel 4 are located on the same side of the open end of the movable cup body 31 to push all the slag piles at the open end of the movable cup body 31 into the powder residue channel 4.

[0039] In some embodiments, as Figures 2 to 5As shown, the brewing cup assembly 3 has at least a first position and a second position. When the movable cup body 31 is directly below the fixed brewing head 21 in the first position, and the brewing cup assembly 3 moves from the first position to the second position to perform a slag pushing movement, the powder residue channel 4 moves to directly below the fixed brewing head 21. Among them, Figure 2 and Figure 3 the brewing cup assembly 3 shown in Figure 4 and Figure 5 is in the first position,

[0040] Figure 5

[0041] In this way, after the brewing cup assembly 3 moves from the first position to the second position, it can complete the slag pushing movement of pushing the slag pile at the open end of the movable cup body 31 into the powder residue channel 4. And in the above-mentioned first position, the movable cup body 31 is directly below the fixed brewing head 21, and in the second position, the powder residue channel 4 moves to directly below the fixed brewing head 21, which can minimize the displacement distance of the brewing cup assembly 3 and make the movement trajectory of the brewing cup assembly 3 more reasonable.

[0042] The above-mentioned first position and second position can be at the same horizontal height, so that the brewing cup assembly 3 can perform a linear reciprocating movement when moving between the first position and the second position. Figure 3 and Figure 5 shown, the fixed brewing head 21 includes a brewing head body 22 and a filter screen 23 provided at the lower end of the brewing head body 22, and the upper end surface of the movable slag scraping member 5 acts on the filter screen 23.

[0043] In this way, the brewing liquid from the brewing head body 22 can be filtered through the filter screen 23, so that the brewing liquid can be filtered through the filter screen 23 and then used to brew the powdery ingredients in the movable cup body 31 to further ensure the taste of the prepared drink.

[0044] The above-mentioned filter screen 23 can be detachably installed at the lower end of the brewing head body 22. For example, it is installed at the lower end of the brewing head body 22 through fasteners, and the fasteners can be screws, bolts, etc.

[0045] In some embodiments, as Figure 6 shown, grooves 41 are provided on both sides of the upper end of the powder residue channel 4, and both ends of the movable slag scraping member 5 are correspondingly embedded in the grooves 41.

[0046] In this way, the movable slag scraping member 5 can be connected to the movable cup body 31 through the grooves 41 of the powder residue channel 4, and thus move in the direction close to the slag pushing structure 11 as the movable cup body 31 performs the slag pushing movement, so as to scrape the powder residue at the lower end of the fixed brewing head 21.

[0047] The above-mentioned groove 41 can be constructed as a long groove, and both ends of the movable slag scraping member 5 can be constructed as long rod-shaped. The two ends of the long rod-shaped movable slag scraping member 5 are clamped into the long groove, so as to realize the stable connection between the movable slag scraping member 5 and the upper end of the powder slag passage 4.

[0048] Both ends of the above-mentioned movable slag scraping member 5 can extend towards the direction where the powder slag passage 4 is located to form hook parts, and the hook parts can be inserted into the opposite sides of the powder slag passage 4, so that the movable slag scraping member 5 can be more stably installed on the powder slag passage 4.

[0049] In some embodiments, as Figure 6 shown, the movable slag scraping member 5 has a first rod portion 51, a second rod portion 52 and a third rod portion 53 connected in sequence. The upper end surface of the second rod portion 52 acts on the lower end of the fixed brewing head 21. The first rod portion 51 and the third rod portion 53 are used to cooperate to support the second rod portion 52, and the first rod portion 51 and the third rod portion 53 are correspondingly embedded in the groove 41. Among them, the second rod portion 52 can be understood as the above-mentioned slag scraping rod.

[0050] The structure of the above-mentioned movable slag scraping member 5 is simple and the manufacturing cost is low, and it can fully contact the lower end of the fixed brewing head 21 through the upper end surface of the second rod portion 52, so as to scrape off the residual powder slag on the lower end of the fixed brewing head 21.

[0051] The length dimension of the above-mentioned second rod portion 52 is greater than the maximum length dimension of the lower end of the fixed brewing head 21, so as to cover the lower end of the fixed brewing head 21 through the second rod portion 52, and achieve the purpose of fully cleaning the residual powder slag on the lower end of the fixed brewing head 21.

[0052] The above-mentioned first rod portion 51, second rod portion 52 and third rod portion 53 can be integrally formed, and the length directions of the first rod portion 51 and the third rod portion 53 are parallel, and the length direction of the second rod portion 52 is perpendicular to the length direction of the first rod portion 51.

[0053] The shape of the upper end surface of the above-mentioned second rod portion 52 is constructed as a shape adapted to the lower end surface of the fixed brewing head 21. For example, when the lower end surface of the fixed brewing head 21 is constructed as a plane, the upper end surface of the second rod portion 52 is also a plane. Another example is that when the lower end surface of the fixed brewing head 21 is constructed as a curved surface, the upper end surface of the second rod portion 52 is a curved surface that can fit the lower end surface of the fixed brewing head 21.

[0054] In some embodiments, as Figures 1 to 6 shown, the powder slag passage 4 is constructed as an inclined slideway, the upward side of the slideway is open, and the high position of the slideway is connected to the movable cup body 31.

[0055] In this way, the chute set obliquely can guide the powder residue scraped by the movable slag scraping member 5 and the slag pile scraped by the slag pushing structure 11 to slide out of the powder residue channel 4 under the action of gravity, ensuring the transportation of the residue without additional structural design, and making the structural design of the powder residue channel 4 more reasonable.

[0056] The embodiment of the present application also provides a beverage preparation device. As Figure 3 , Figure 5 and Figure 7 shown, the beverage preparation device includes the above-mentioned brewing device for the beverage preparation device. The beverage preparation device further includes a frame 6, a driving component 7 and a transmission component 8 provided on the frame 6. The driving component 7 is used to drive at least the transmission component 8 to move linearly in the first direction, and the transmission component 8 is used to drive the movable cup body 31 to move linearly in at least the second direction relatively close to or away from the slag pushing structure 11; wherein, the first direction and the second direction are perpendicular to each other.

[0057] The above-mentioned driving component 7 can be a driving motor, which can provide a power source for the transmission component 8, so as to drive the transmission component 8 to move linearly in the first direction. Among them, the transmission component 8 can be one of the following structures or a combination of multiple structures: a lead screw nut structure, a worm and worm gear structure, a gear transmission structure, and a belt transmission structure.

[0058] Exemplarily, the transmission component 8 is a lead screw nut structure. The driving component 7 can drive the lead screw to rotate, so that the nut on the lead screw can move up and down along the lead screw. The above-mentioned first direction can be understood as the vertical direction, that is, the nut of the transmission component 8 can move up and down in the vertical direction.

[0059] The movable cup body 31 can be connected to the transmission component 8 to move linearly at least in the second direction along with the transmission component 8. The movable cup body 31 can be specifically connected to the transmission component 8 through the pusher 9 described below. The structure of the pusher 9 can be seen below and will not be elaborated here. Of course, the transmission component 8 can also drive the movable cup body 31 to move linearly in the first direction relatively close to or away from the fixed brewing head 21, so that the movable cup body 31 can move upward to approach the fixed brewing head 21 for powder pressing operation and brewing operation, and move downward to move away from the fixed brewing head 21 for subsequent slag pushing movement after brewing.

[0060] The above-mentioned first direction can be understood as the vertical direction, and the second direction can be understood as the horizontal direction.

[0061] The beverage preparation device using the above brewing device can, through the movable cup body 31 movably arranged on the brewing support 1, and the powder residue channel 4 and the movable residue scraping member 5 arranged on the movable cup body 31, first make a powder pressing movement when the movable cup body 31 approaches the fixed brewing head 21. After the powder residue remains at the lower end of the fixed brewing head 21, the movable residue scraping member 5 can scrape the powder residue at the lower end of the fixed brewing head 21 into the powder residue channel 4 along with the slag pushing movement of the movable cup body 31. The above structure does not need to set other movement structures to drive the movable residue scraping member 5 to move. The movable residue scraping member 5 can fully scrape the powder residue remaining at the lower end of the fixed brewing head 21 along with the movement of the movable cup body 31, making the structural design of the brewing device more reasonable, reducing the influence of the remaining powder residue on the subsequent beverage preparation, achieving the purpose of preparing a beverage with a better taste, and more avoiding the occurrence of food safety problems caused by the deterioration of the remaining powder residue.

[0062] In some embodiments, such as Figure 1 、 Figure 3 、 Figure 5 and Figure 7 shown, the brewing device is detachably arranged on the machine frame 6. The brewing device further includes a pushing member 9 detachably connected to the transmission assembly 8. The pushing member 9 acts on the movable cup body 31. When the brewing device is installed on the machine frame 6, the pushing member 9 is connected to the transmission assembly 8. The transmission assembly 8 is used to drive the movable cup body 31 to make a linear motion in the second direction through the pushing member 9.

[0063] In this way, the brewing device detachably arranged on the machine frame 6 can be used to detach the whole brewing device from the machine frame 6 after use, which is convenient for thoroughly cleaning the brewing device. And the detachably connected transmission assembly 8 and the pushing member 9 can be connected when the brewing device is installed on the machine frame 6, and can be disassembled when the brewing device is detached from the machine frame 6, so that the transmission assembly 8 can stably drive the movable cup body 31 to make a linear motion through the pushing member 9 when the brewing device is installed on the machine frame 6.

[0064] A self-locking assembly can be arranged on the above brewing device. The self-locking assembly can lock the whole brewing device on the machine frame 6, and can release the lock on the whole brewing device after being stressed, so that the brewing device can be detached from the machine frame 6, which is beneficial to disassembling the brewing device for thorough cleaning.

[0065] Such as Figure 1 shown, the above pushing member 9 can include a slide rod 92 and a push block 91 sleeved on the slide rod 92. One end of the push block 91 can be detachably connected to the transmission assembly 8, and the other end can be connected to the movable cup body 31, so that the transmission assembly 8 can drive the push block 91 to slide on the slide rod 92 when the brewing device is installed on the machine frame 6. One end of the push block 91 acting on the movable cup body 31 can make a swinging motion, thereby driving the movable cup body 31 to make a linear motion in the second direction through the push block 91.

[0066] One end of the above-mentioned pushing block 91 may be provided with a plurality of bumps, and the plurality of bumps may be detachably connected to the transmission assembly 8, so that the pushing block 91 can move up and down along the first direction along with the transmission assembly 8.
