[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0047] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0048] The utility model provides a beverage preparation device. The beverage preparation device includes a machine body and a brewing device arranged on the machine body. It can be understood that the beverage preparation device can be, but is not limited to, electrical equipment such as a coffee machine, a soymilk machine, and a grain wall breaking machine. Take the beverage preparation device as an example, that is, a coffee machine: when the beverage preparation device directly processes coffee powder, the brewing device is directly connected to the external coffee powder, and the external coffee powder is extracted and brewed. Among them, the external powder can be, for example, coffee capsules, small cans of coffee powder, bagged coffee powder, etc. When the beverage preparation device directly processes coffee beans, the beverage preparation device can also include a grinding device, which is connected to the coffee beans and grinds the coffee beans, or coffee powder of a desired coarseness; the discharge port of the grinding device is connected to the feed port of the brewing device, and the coffee powder obtained by grinding the grinding device is connected to the brewing device for brewing to extract and brew the coffee powder.

[0049] Since the main inventive point of the present application is to improve the brewing device, in the following embodiments, the brewing device is mainly described in conjunction with the accompanying drawings.

[0050] See also Figures 1 to 11 The utility model provides a brewing device, which includes a brewing cylinder 200, a cleaning member 300 and a driving mechanism. The brewing cylinder 200 forms an area to be cleaned; the cleaning member 300 includes a first cleaning unit 310 and a second cleaning unit 320, and at least one of the cleaning member 300 and the brewing cylinder 200 is movably arranged relative to the other one, so that the cleaning member 300 and the brewing cylinder 200 have a relative movable stroke, and in the relative movable stroke, the first cleaning unit 310 and the second cleaning unit 320 are both slidably abutted against the area to be cleaned to remove dirt in the area to be cleaned; the driving mechanism is drivingly connected to the movably arranged cleaning member 300 and / or the brewing cylinder 200; wherein, when performing the relative movable stroke, the cleaning member 300 has a proximal end close to the area to be cleaned and a distal end away from the area to be cleaned, the proximal end of the second cleaning unit 320 is arranged closer to the area to be cleaned than the proximal end of the first cleaning unit 310, and the softness of the second cleaning unit 320 is greater than the softness of the first cleaning unit 310.

[0051] In the technical solution provided by the utility model, under the drive of the driving mechanism, the cleaning member 300 and the brewing cylinder 200 generate a relative moving stroke along the first direction. During this process, the first cleaning unit 310 and the second cleaning unit 320 both slide and abut against the area to be cleaned, and can provide at least two cleaning operations to the area to be cleaned. Among them, since the second cleaning unit 320 contacts the area to be cleaned earlier than the first cleaning unit 310, and the second cleaning unit 320 is softer, it can increase the contact area with the area to be cleaned and increase the surface fit with the area to be cleaned through elastic deformation when the area to be cleaned is cleaned for the first time, which helps to increase the comprehensiveness of the cleaning of the area to be cleaned; then, when the first cleaning unit 310 cleans the area to be cleaned for the second time, since the first cleaning unit 310 is softer and has a relatively large rigidity, it can enhance the contact and abutment force between the area to be cleaned and the area to be cleaned, thereby helping to increase the thoroughness of the cleaning of the area to be cleaned. The present application helps to optimize the cleaning effect of the area to be cleaned of the brewing cylinder 200 as a whole.

[0052] In addition, in the present design, the brewing device may further include a base 100, which mainly provides a mounting carrier for the brewing cylinder 200, the cleaning member 300, the driving mechanism and other functional components. The base 100 may be one or more of a plate-like structure, a block-like structure, a box structure and a frame structure. The base 100 may be a structure specially provided for the brewing device, and then when the brewing device is applied to the beverage preparation equipment, the base 100 is fixedly or movably installed with the body in the beverage preparation equipment. Of course, the base 100 may also be directly used for the fixed body in the beverage preparation equipment, such as the body, which helps to integrate the above-mentioned brewing cylinder 200, the cleaning member 300, the driving mechanism and other functional components of the brewing device on the body.

[0053] For ease of understanding, in the following embodiments, the brewing device is placed horizontally on the platform as an example, and thus has a horizontal plane and an up-down direction, wherein the horizontal plane has a first direction and a second direction arranged crosswise. However, it should be noted that the horizontal plane and the up-down direction do not constitute a limitation on the specific application of the first direction and the second direction. In other applications, the first direction and the second direction may be directions other than the horizontal plane and the up-down direction. Among them, the first direction in the following embodiments mainly refers to the relative movement direction between the cleaning component and the brewing cylinder.

[0054] In view of the above, the brewing cylinder 200 can be specifically arranged at the lower side of the base 100, and the above-mentioned grinding device can be specifically arranged at the upper side of the base 100, so that the coffee powder ground by the grinding device can be introduced into the brewing cylinder 200 by means of gravity. The brewing cylinder 200 is suspended below the base 100, and the cleaning member 300 can be arranged between the base 100 and the brewing cylinder 200, that is, located above the brewing cylinder 200, so the near-far direction described in the following embodiments is specifically the up-down direction.

[0055] Next, the relative movement stroke can be formed by one of the cleaning member 300 and the brewing cylinder 200 being movably arranged along the first direction, or by both the cleaning member 300 and the brewing cylinder 200 being movably arranged along the first direction, and the two being movable to approach each other and to move away from each other. For ease of understanding, in the following embodiments, the cleaning member 300 is fixed relative to the base 100, and the brewing cylinder 200 is movably arranged relative to the base 100 along the first direction as an example for description.

[0056] Specifically, Figure 1As shown, the base body 100 is arranged in a plate shape and extends and spreads out roughly along a horizontal plane. The base body 100 defines a powder receiving position 110 and a brewing position 120 that are spaced apart corresponding to the moving path of the brewing cylinder 200, and the first direction is correspondingly defined between the powder receiving position 110 and the brewing position 120. The driving mechanism includes a first driving mechanism 400. Under the drive of the first driving mechanism 400, the brewing cylinder 200 is switched between the powder receiving position 110 and the brewing position 120. The first driving mechanism 400 can drive the brewing cylinder 200 to perform a linear translation between the powder receiving position 110 and the brewing position 120. At this time, the linear connection direction between the powder receiving position 110 and the brewing position 120 constitutes the first direction; of course, the first driving mechanism 400 can also drive the brewing cylinder 200 to perform a curved translation or rotational movement between the powder receiving position 110 and the brewing position 120. At this time, the curved connection direction between the powder receiving position 110 and the brewing position 120 constitutes the first direction.

[0057] The composition of the first driving mechanism 400 is specifically configured to adapt to the movement form of the brewing cylinder 200. When the brewing cylinder 200 performs linear translation, the first driving mechanism 400 can be directly configured as a driver such as a linear cylinder, a motor, or a combination of a driver and a transmission component. The transmission component can be a gear set, a screw nut mechanism, a pulley assembly, a gear rack assembly, etc.

[0058] In view of this, the cleaning member 300 can be fixedly arranged on the moving path of the brewing cylinder 200, that is, located on any side of the powder receiving position 110 and / or the brewing position 120 in the first direction, so that under the drive of the first driving mechanism 400, the brewing cylinder 200 can move through the cleaning member 300 without additionally changing the moving path of the brewing cylinder 200 and additionally setting up other driving mechanisms.

[0059] Furthermore, in one embodiment, the cleaning member 300 is fixedly disposed between the powder receiving position 110 and the brewing position 120. In this way, when the first driving mechanism 400 drives the brewing cylinder 200 to and fro between the powder receiving position 110 and the brewing position 120, the cleaning member 300 can move through the cleaning member 300 without extending the moving path length of the brewing cylinder 200. Moreover, when moving from the powder receiving position 110 to the brewing position 120, the cleaning member 300 can scrape the coffee powder that may remain in the area to be cleaned of the brewing cylinder 200 and scrape it into the brewing cavity of the brewing cylinder 200; when returning to the powder receiving position 110 from the brewing position 120, the cleaning member 300 can scrape the coffee residues remaining in the area to be cleaned of the brewing cylinder 200.

[0060] And / or in one embodiment, the cleaning member 300 is disposed closer to the brewing position 120 than the powder receiving position 110. Since hot water or hot milk is introduced into the brewing chamber of the brewing cylinder 200 at the brewing position 120 in order to extract and brew the coffee powder, the temperature in the brewing chamber is high and the remaining coffee residues are in a softened state. At this time, by disposing the cleaning member 300 close to the brewing position 120, the coffee residues in a softened state can be cleaned immediately, avoiding cleaning after the coffee residues are cooled and hardened, which increases the difficulty of cleaning the coffee residues.

[0061] In view of the above, a brewing cavity for receiving coffee powder is formed inside the brewing cylinder 200. It can be understood that the brewing cylinder 200 can be configured as a semi-enclosed container with a feed port and a discharge port. Or in one embodiment, the brewing cylinder 200 includes a cylinder body 210 and a first piston member 220, and the cylinder body 210 is penetrated by a channel 211 in the direction close to and away from the cleaning member 300 (i.e., in the up and down directions); the first piston member 220 is reciprocally movably disposed in the channel 211 along the extension direction of the channel 211, and the first piston member 220 is sealed and connected to the inner wall of the channel 211 to seal the lower section of the channel 211, thereby enclosing the above-mentioned brewing cavity.

[0062] The first piston member 220 is provided with a plurality of water inlet holes, and the water inlet holes are used to connect external water to the channel 211. The external water may be hot water, hot milk, etc.

[0063] The second driving mechanism is disposed on the base body 100 and is drivingly connected to the first piston member 220 .

[0064] In specific applications, one end surface of the cylinder body 210 close to the cleaning member 300 is the first end surface, and the first end surface defines the area to be cleaned. In this way, the coffee powder dropped on the first end surface, or the coffee residue discharged from the brewing chamber and retained on the first end surface can be removed by the cleaning member 300. And / or when the first piston member 220 moves to extend out of the first end surface, the end surface of the first piston member 220 defines the area to be cleaned. When the brewing cylinder 200 completes a single brewing and outputs the coffee beverage to the outside, the second driving mechanism can drive the first piston member 220 to move toward the first end surface, and the coffee residue remaining on the inner wall of the channel 211 is pushed outward and accumulated on the end surface and / or the first end surface of the first piston member 220 for cleaning by the cleaning member 300.

[0065] It can be understood that the second drive mechanism and the first drive mechanism 400 can be separately arranged, or the first drive mechanism 400 and the second drive mechanism are shared, that is, the first drive mechanism 400 is reused for the second drive mechanism. For example, the first drive mechanism 400 includes a driver and a switching assembly connected to the driver, and the switching assembly can convert the power output of the driver into driving the brewing cylinder 200 to move in the first direction, and switch to the first piston member 220 to move in the up and down direction. Wherein, the driver is, for example, a motor, and the switching assembly may include a nut directly or indirectly connected to the motor, a lead screw threadedly connected to the nut, and a sleeve sleeved on the outside of the lead screw, the sleeve is fixedly connected to the brewing cylinder 200, the lead screw is fixedly connected to the first piston member 220, and one of the sleeve and the lead screw is provided with a guide groove extending in the first direction and the up and down direction respectively, and the other is provided with a guide protrusion slidably connected to the guide groove.

[0066] In view of the above, regarding the arrangement of the cleaning member 300:

[0067] Please combine Figures 4 to 5 In one embodiment, the first cleaning unit 310 and the second cleaning unit 320 are arranged in sequence from far to near. That is, the first cleaning unit 310 is arranged directly above the second cleaning unit 320. In this way, when the relative movement stroke is performed, the second cleaning unit 320 first slides and abuts against the area to be cleaned, and performs the first cleaning on the area to be cleaned. Since the second cleaning unit 320 is softer, during the process of sliding and abutting against the area to be cleaned, the second cleaning unit 320 bends and deforms, so that the first cleaning unit 310 then slides and abuts against the area to be cleaned, and performs the second cleaning on the area to be cleaned.

[0068] Alternatively, in one embodiment, the first cleaning unit 310 and the second cleaning unit 320 are sequentially arranged along the direction from the brewing position 120 to the powder receiving position 110. In this way, when the first driving mechanism 400 drives the brewing cylinder 200 to switch between the powder receiving position 110 and the brewing position 120, the first cleaning unit 310 and the second cleaning unit 320 sequentially slide and abut against the area to be cleaned, and since the proximal end of the second cleaning unit 320 is arranged closer to the proximal end of the first cleaning unit 310 than the area to be cleaned, the protruding portion of the second cleaning unit 320 from the first cleaning unit 310 can be used for the second cleaning unit 320 to deform after receiving force.

[0069] In specific applications, the first cleaning unit 310 is plate-shaped and made of elastic material, such as a rubber block or a rubber plate. During the relative movement, at least the proximal surface of the first cleaning unit 310 slides and abuts against the area to be cleaned. That is, when the brewing cylinder 200 moves through the cleaning member 300, the proximal surface of the first cleaning unit 310 just slides and abuts against the surface of the area to be cleaned; or when the brewing cylinder 200 moves through the cleaning member 300, at least the proximal section of the first cleaning unit 310 slides and abuts against the surface of the area to be cleaned, that is, it is in interference abutment with the surface of the area to be cleaned, so that during the relative movement, at least the proximal section of the first cleaning unit 310 is deformed by force.

[0070] Furthermore, in one embodiment, the flexibility of the first cleaning unit 310 is set to increase from far to near, so that the near section of the first cleaning unit 310 can be made more flexible and easier to deform elastically, and while flexibly contacting the surface of the area to be cleaned, it helps to increase the concave-convex fit with the surface of the area to be cleaned through elastic deformation, and increase the contact area with the surface of the area to be cleaned. In addition, the far end of the first cleaning unit 310 can also be made less flexible and more rigid, which helps to provide sufficient structural strength for the first cleaning unit 310 as a whole, and avoid the first cleaning unit 310 as a whole. Failure due to insufficient rigidity leads to overall deformation of the unit.

[0071] It should be noted that the increase setting can be a linear continuous increase or a step-by-step increase.

[0072] There are many ways to achieve the change in the softness of the first cleaning unit 310:

[0073] In one embodiment, the different flexibility of the first cleaning unit 310 can be achieved by distinguishing the materials of different plate segments from far to near. Specifically, the first cleaning unit 310 may include a fixed plate segment 311 and a deformable plate segment 312 connected in sequence from far to near. The fixed plate segment 311 and the deformable plate segment 312 are detachably connected. There are many ways of detachable connection, such as one or more of the following ways: screw fixation, snap fixation, adhesive fixation, adsorption fixation, etc.

[0074] And / or in one embodiment, the difference in flexibility between the two can be achieved by configuring the first cleaning monomer 310 with different plate segments from far to near. Specifically, the thickness of at least the near segment of the first cleaning monomer 310 is thinned in the direction from far to near. By thinning the thickness of the near segment of the first cleaning monomer 310, the flexibility of the near segment of the first cleaning monomer 310 is greater than the flexibility of the far end of the first cleaning monomer 310, and it is easier to deform under force.

[0075] In addition, in one embodiment, the second cleaning unit 320 is configured as a brush body, and at least the bristle part of the second cleaning unit 320 is made of a flexible material, and when the relative movement stroke is performed, the bristles of the second cleaning unit 320 are in interference contact with the area to be cleaned. The bristle part of the brush body can be made of a flexible material such as cloth, or can be further made of an elastic material such as a rubber strip. When the brewing cylinder 200 moves through the cleaning member 300, at least the bristles of the second cleaning unit 320 slide and contact with the surface where the area to be cleaned is located, that is, in interference contact with the surface where the area to be cleaned is located, so that during the relative movement, at least the near section of the second cleaning unit 320 is deformed by force. In this way, the bristle part of the second cleaning unit 320 can be deformed by force, and while flexibly contacting with the surface where the area to be cleaned is located, it helps to increase the concave-convex fit with the surface where the area to be cleaned is located through deformation, and increase the contact area with the surface where the area to be cleaned is located.

[0076] In addition, based on any of the above embodiments, in a further solution, the plane where the area to be cleaned is located is a reference plane. In view of the above, the reference plane can be the plane where the first end face is located, or the plane where the end surface of the first piston member 220 that extends movably from the first end face is located. The cleaning member 300 has an orthographic projection area on the reference plane, and in a second direction perpendicular to the first direction, the orthographic projection area at least covers the area to be cleaned. In this way, when the cleaning member 300 and the brewing cylinder 200 perform a relative motion stroke, the cleaning member 300 can clean the entire area to be cleaned at one time.

[0077] Specifically, when the brewing cylinder 200 is configured to be cylindrical, the cleaning member 300 may be configured to extend in an arc shape along the circumference of the brewing cylinder 200, and the arc length of the arc shape is not less than half of the circumference of the brewing cylinder 200. Alternatively, the cleaning member 300 may be configured to be a straight line extending along the second direction, and the length of the straight line is not less than the maximum width of the brewing cylinder 200 in the second direction.

[0078] When applying specific Figures 6 to 11When the brewing cylinder 200 moves to the brewing position 120, and the coffee beverage is prepared and taken out, the first piston member 220 moves in the up-down direction toward the direction of the cleaning member 300, that is, toward the cylinder mouth of the cylinder body 210, so that during the movement, the coffee grounds 5 remaining on the inner wall of the channel 211 are scraped out and driven to the cylinder mouth of the cylinder body 210. At this time, the upper end surface of the first piston member 220 defines the area to be cleaned. Then, the cleaning member 300 and the brewing cylinder 200 generate relative movement along the first direction, so that the first cleaning unit 310 and the second cleaning unit 320 can clean the area to be cleaned respectively, and during the movement, the coffee grounds 5 on the first piston member 220 are scraped off, so that the coffee grounds 5 in the brewing cylinder 200 are effectively cleaned.

[0079] In addition, in one embodiment, the cleaning member 300 is rotatably arranged relative to the base 100. At this time, the distal end of the cleaning member 300 is rotatably connected to the base 200 to drive the proximal end of the cleaning member 300 to flip along the first direction. Based on this, when the brewing cylinder 200 moves to the brewing position 120, and the coffee beverage is prepared and the coffee beverage is taken out, the first piston member 220 moves in the up-down direction toward the direction where the cleaning member 300 is located, that is, toward the cylinder mouth of the cylinder body 210, so that during its movement, the coffee residue 5 remaining on the inner wall of the channel 211 is scraped out and driven to the cylinder mouth near the cylinder body 210. At this time, the upper end surface of the first piston member 220 defines the area to be cleaned. Then, the cleaning member 300 can flip toward the direction where the cylinder body 210 is located, and at least partially extend into the cylinder body 210. The cleaning member 300 pushes the coffee grounds 5 out of the cylinder body 210 during the continuous turning process, which helps to clean the inner wall of the cylinder body 210 and the end surface of the first piston member 220 at the same time.

[0080] In addition, in another embodiment, when the brewing device further includes a pressing mechanism, the pressing mechanism is used to press the coffee powder in the brewing cylinder 200 when the brewing cylinder 200 moves to the brewing position 120, so that the coffee powder is pressed into a cake shape. Specifically, the pressing mechanism may include a second piston member movable in the up-down direction, and the second piston member may extend into the channel 211 to perform a powder pressing operation. Based on this, the cleaning member 300 may also include a third cleaning unit located at the upper end of the first cleaning unit 310, and the setting structure between the third cleaning unit and the upper end of the first cleaning unit 310 is substantially the same as the setting structure between the second cleaning unit 320 and the lower end of the first cleaning unit 310. In this way, when the lower ends of the second cleaning unit 320 and the first cleaning unit 310 jointly clean the coffee grounds 5 at the first piston 220, the upper ends of the third cleaning unit and the first cleaning unit 310 can also clean the lower surface of the second piston.

[0081] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
