Description

Technical Field

[0001] This application belongs to the field of beverage brewing technology, and in particular relates to a skimming component and a brewing mechanism. Background Technology

[0002] In existing fully automatic coffee machines, the coffee-making process begins with the brewing chamber vertically receiving coffee grounds, which then rotate into an inclined track. The brewing head tamps the coffee grounds within the brewing chamber. After tamping, a water pump injects water into the brewing chamber to brew the coffee. After brewing, a grounds-pushing component, driven by a transmission mechanism, pushes the grounds out of the brewing chamber, and a scraping component scrapes the grounds into a collection tray. For example, a coffee brewing device disclosed in Chinese Patent No. CN 106859344 B uses a scraping structure to scrape the grounds after the pushing component pushes them out of the brewing chamber. This scraping structure includes a scraper blade and a torsion spring. The scraper blade scrapes the grounds with the coordination of the brewing component and the support frame, and then the torsion spring returns it to its original position. This results in poor movement stability and inconsistent scraping performance. Furthermore, the torsion spring is prone to failure after prolonged use, leading to incomplete scraping and the accumulation of grounds. In addition, the fixed design of the scraper not only makes it difficult to clean itself, but also makes it difficult to clean the brewing head. Utility Model Content

[0003] In view of at least one of the above-mentioned problems in the prior art, the purpose of this application is to provide a slag scraping component and a brewing mechanism with good slag scraping effect to reduce powder residue.

[0004] The technical solution adopted in this application embodiment is a slag scraping assembly for use in a brewing mechanism. The brewing mechanism includes a support, a brewing head fixed on the support, a brewing container capable of moving along the support, and a slag pushing assembly for pushing out powder residue from the brewing container. The slag scraping assembly includes: A fixing component is mounted on the support of the brewing mechanism; A slag scraping component is detachably mounted on the fixed component. The slag scraping component includes a slag scraping part made of a flexible material so that during the slag scraping process, the slag scraping part can be closely fitted with the upper surface of the brewing container and the upper surface of the slag pushing component that pushes against the upper surface of the brewing container.

[0005] In a preferred embodiment, the fixing member has two snap-fit ​​portions on each side; the bracket includes two opposing frames, each frame having a slot that matches the shape of the two snap-fit ​​portions. The two snap-fit ​​portions are snapped into the two slots in a one-to-one correspondence to secure the fixing member to the bracket. The cooperation of the snap-fit ​​portions and slots facilitates the installation of the fixing member on the bracket and maintains the stability of the fixing member after installation.

[0006] In a preferred embodiment, the fixing member includes a rod portion located between the two frame bodies and extending laterally, with two locking portions formed at each end of the rod portion; The scraping component includes a vertically arranged plate. The scraping portion is formed on the lower side of the plate, and an opening groove is provided on the upper side of the plate. The opening groove extends laterally and penetrates to both ends of the upper side of the plate. The size of the opening groove is smaller than the radial dimension of the rod. Under external force, the rod can open the opening groove and enter the opening groove. When the opening groove returns to its original position, it covers and confines the rod within the opening groove, thereby limiting the plate to the rod. By providing an opening groove on the plate, the plate can be detachably connected to the rod of the fixing component, and the assembly and disassembly are quick and convenient.

[0007] In a preferred embodiment, the fixing member further includes a first plate portion, which is vertically arranged. The upper side of the first plate portion is connected to the periphery of the rod portion, the axis of the rod portion is parallel to the plate surface of the first plate portion, and the two ends of the upper side of the first plate portion are flush with and connected to the two ends of the rod portion, so that the two ends of the upper side of the first plate portion and the two ends of the rod portion cooperate to form a cylindrical limiting post connecting the rectangular bone position to the snap-fit ​​portion. The above structure allows the snap-fit ​​portion to form a special shape including the limiting post and the rectangular bone position, realizing a stable connection between the fixing member and the bracket.

[0008] In a preferred embodiment, the fixing member further includes a second plate portion, which is vertically arranged. The upper side of the second plate portion is connected to the lower side of the first plate portion. The dimension of the second plate portion in the lateral direction is smaller than that of the first plate portion in the lateral direction, so that the left and right ends of the first plate portion protrude outward from the left and right ends of the second plate portion, respectively. The scraper member has a receiving groove within its plate body that communicates with the opening groove, and the first and second plate portions of the fixing member extend into the receiving groove via the opening groove. This further increases the stability of the connection between the scraper member and the fixing member.

[0009] In a preferred embodiment, the rod portion, the first plate portion, and the second plate portion are an integral structure; The outer diameter of the rod is greater than the thickness of the first plate. The thickness of the second plate portion is the same as the thickness of the first plate portion.

[0010] In a preferred embodiment, the plate body of the slag scraping component and the slag scraping part are an integral structure, both made of silicone material; the thickness of the slag scraping part gradually decreases from top to bottom. This simplifies the structure of the slag scraping component while ensuring effective slag scraping.

[0011] A brewing mechanism includes a support, a brewing head fixed to the support, a brewing container movable along the support, and a shovel assembly for pushing out coffee grounds from the brewing container. The brewing mechanism further includes a scraper assembly as described in any of the above embodiments, the scraper assembly being disposed on the support and used to scrape away coffee grounds from the upper surface of the brewing container and the upper surface of the shovel assembly. Because the brewing mechanism includes a thorough scraper assembly, it achieves better and more stable coffee brewing results.

[0012] In a preferred embodiment, the bracket includes two opposing frames, each of which is provided with a slot. The slot includes a first slot with a circular cross-section and a second slot with a rectangular cross-section. The first slot and the second slot are connected to form an irregularly shaped slot. The fixing component has two locking parts on each side. Each locking part includes a cylindrical limiting post and a rectangular rib. One side of the rectangular rib is connected to the periphery of the limiting post. The limiting post is locked into the first groove, and the rectangular rib is locked into the second groove. The specially shaped grooves and the specially shaped locking parts that mate with them facilitate convenient and stable installation of the fixing component onto the bracket.

[0013] In a preferred embodiment, a support rod connects the two frames. The axis of the support rod is parallel to the axis of the limiting post. The support rod is positioned close to the scraping section of the scraping component and downstream of the scraping section in the lateral movement direction of the brewing container. The axis of the support rod is perpendicular to the lateral movement direction of the brewing container. The support rod not only supports the two frames but also limits the deformation of the scraping section, ensuring the smoothness of the scraping process and providing a stable and reliable scraping effect.

[0014] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: The scraping component of this application, with its excellent elasticity and flexibility, maintains good contact with the upper surface of the brewing container and the upper surface of the pushing component during the scraping process, thereby reducing powder residue to a certain extent and resulting in better and more stable subsequent coffee extraction. Furthermore, since the scraping component remains stationary, there is no problem of unstable movement during the scraping process.

[0015] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this application.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the described embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Unless otherwise defined, the technical or scientific terms used in this application shall have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0030] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.

[0031] This application provides a slag scraping assembly for use in a brewing mechanism. For example... Figure 3 , Figure 4 and Figure 11 As shown, the brewing mechanism includes a support, a brewing head 32 fixed on the support, a brewing container 33 that can move along the support, and a slag pushing component 34 for pushing out the powder residue formed after brewing in the brewing container 33.

[0032] like Figures 1 to 10 As shown, the slag scraping assembly of this embodiment includes a fixing member 1 and a slag scraping member 2. The fixing member 1 is mounted on the support of the brewing mechanism. The slag scraping member 2 is detachably mounted on the fixing member 1. The slag scraping member 2 includes a slag scraping part 22, which is made of a flexible material so that during the slag scraping process, the slag scraping part 22 can fit against the upper end surface of the brewing container 33 and the upper end surface of the slag pushing assembly 34 that pushes against the upper end surface of the brewing container 33.

[0033] The scraping assembly of this embodiment remains stationary during the scraping process and maintains contact with the surface to be scraped, reducing residue and ensuring better and more stable brewing results. Furthermore, the scraping part 22 of the scraping component 2, with its good elasticity and flexibility, reduces powder residue to a certain extent, resulting in more thorough scraping and better and more stable coffee extraction. Moreover, the scraping component 2 is detachably connected to the fixing component 1, facilitating cleaning of both the scraping component 2 and the brewing head 32.

[0034] In some embodiments, such as Figure 1 and Figure 2 As shown, the fixing member 1 has two snap-fit ​​parts 13 on each side. Figure 3 and Figure 4 As shown, the bracket includes two opposing frame bodies 31. Each frame body 31 has a slot 311 that matches the shape of two snap-fit ​​parts 13. The two snap-fit ​​parts 13 are inserted into the two slots 311 one-to-one to secure the fixing member 1 to the bracket. The cooperation between the snap-fit ​​parts 13 and the slots 311 facilitates the installation of the fixing member 1 on the bracket and maintains the stability of the fixing member 1 after installation. Furthermore, the snap-fit ​​installation method of the fixing member 1 allows it to be detached from the bracket. This ensures that even when the vertical dimension of the fixing member 1 is large, it can be removed from the bracket, avoiding the problem of difficulty in cleaning the brewing head 32 due to the obstruction of the brewing head 32 by the fixing member 1 and the scraper 2. Of course, when the vertical dimension of the fixing member 1 is small, it can also be designed to be non-detachable from the bracket. That is, in addition to retaining the connection between the snap-fit ​​parts 13 and the slots 311, a connector can be used to further connect the fixing member 1 to the bracket. Alternatively, the fixing component 1 can be directly fixed to the bracket using screws or other connecting parts.

[0035] Furthermore, such as Figure 2 As shown, the fixing member 1 includes a rod 11, which is located between the two frame bodies 31 (see...). Figure 3 ), and extends laterally, with two snap-fit ​​portions 13 formed at each end of the rod 11.

[0036] Continue to combine Figure 2 The scraper component 2 includes a vertically arranged plate 21, with a scraper portion 22 formed on the lower side of the plate 21. An opening groove 23 is provided on the upper side of the plate 21, extending laterally and penetrating to both ends of the upper side of the plate 21. The opening 231 of the opening groove 23 also extends laterally and penetrates both ends of the groove wall in the lateral direction. The size of the opening groove 23 (the circumferential dimension along the groove) is smaller than the radial dimension of the rod 11, so that the rod 11 can open the opening 231 and enter the opening groove 23 under external force. When the opening 231 returns to its original position, it covers and confines the rod 11 within the opening groove 23, thus confining the plate 21 to the rod 11. (See [reference]). Figure 1 By providing an opening slot 23 on the plate 21, the plate 21 can be detachably connected to the rod 11 of the fixing member 1, and the assembly and disassembly are quick and convenient.

[0037] In some embodiments, such as Figure 2 As shown, the fixing member 1 also includes a first plate portion 12, which is vertically arranged, i.e., the first plate portion 12 is parallel to the plate body 21 of the scraper member 2. The upper side of the first plate portion 12 is connected to the periphery of the rod portion 11, and the axis of the rod portion 11 is parallel to the plate surface of the plate portion. The two ends of the upper side of the first plate portion 12 are flush with and connected to the two ends of the rod portion 11, so that the two ends of the upper side of the first plate portion 12 and the two ends of the rod portion 11 cooperate to form a cylindrical limiting post 131 connecting to the locking portion 13 of the rectangular bone position 132. By connecting the first plate portion 12 to the rod portion 11, the locking portion 13 forms a special shape including the limiting post 131 and the rectangular bone position 132, achieving a stable connection between the fixing member 1 and the bracket.

[0038] Furthermore, continue to combine Figure 2 The fixing member 1 also includes a second plate portion 14, which is vertically arranged. The upper side of the second plate portion 14 is connected to the lower side of the first plate portion 12. The lateral dimension of the second plate portion 14 is smaller than that of the first plate portion 12, so that the left and right ends of the first plate portion 12 protrude outward from the left and right ends of the second plate portion 14, respectively. The plate body 21 of the scraper member 2 has a receiving groove 211 communicating with the opening groove 23. The first plate portion 12 and the second plate portion 14 of the fixing member 1 extend into the receiving groove 211 through the opening groove 23. In this way, the stability of the connection between the scraper member 2 and the fixing member 1 can be further increased. When the plate body 21 is made of plastic material, the strength of the upper part of the plate body 21 can be increased.

[0039] Optionally, the rod 11, the first plate 12, and the second plate 14 are a single integrated structure. This integrated structure not only reduces the number of parts but also improves the overall stability of the fixing member 1.

[0040] The outer diameter of the rod 11 is larger than the thickness of the first plate 12, so that the cross-section (the cross-section perpendicular to the rod 11) of the snap-fit ​​part 13 formed by the end communication of the rod 11 and the first plate 12 is irregularly shaped (roughly a key-like shape with a circular upper part and a rectangular lower part), which facilitates snap-fit ​​with the slot 311 and prevents it from detaching from the bracket.

[0041] The thickness of the second plate 14 is the same as that of the first plate 12, but the vertical dimension of the second plate 14 is larger than that of the first plate 12. Designing both plates to have the same thickness allows for the design of the receiving groove 211 within the scraper component 2 to have a consistent width from top to bottom, facilitating the manufacturing of the receiving groove 211. Designing the vertical dimension of the first plate 12 to be smaller than that of the second plate 14 avoids excessively large dimensions for the snap-fit ​​part 13 and the snap-fit ​​groove 311 on the frame 31, which would affect loading / unloading and the strength of the support.

[0042] In some embodiments, continue to combine Figure 1 and Figure 2 The thickness of the scraper section 22 gradually decreases from top to bottom. This increases the flexibility and deformability of the scraper section 22, allowing it to fit more tightly against the upper surface of the brewing container 33 and the upper surface of the slag pushing assembly 34, thus removing the powder and slag more thoroughly.

[0043] It is understandable that, in addition to the scraping part 22 being made of a flexible material, the plate 21 of the scraping component 2 can also be made of a flexible material. For example, the scraping component 2 could be a one-piece structure, that is, roughly plate-shaped, and made of silicone. This simplifies the structure of the scraping component 2 while ensuring the scraping effect.

[0044] To facilitate the design of the opening slot 23 on the upper side of the plate 21, two semi-shells with approximately semi-circular cross-sections can be provided on the upper side of the plate 21. The two semi-shells interlock to form a cylindrical shape (hollow cylinder) to cover the rod portion 11 of the fixing component 1. The lower sides of the two semi-shells are respectively connected to the two edges of the upper side of the plate 21, and the upper sides of the two semi-shells face each other, forming a slot 231. The plate 21, the opening slot 23 on its upper side, and the scraper portion 22 on its lower side are integrally injection molded.

[0045] This application also provides a brewing mechanism. For example... Figures 3 to 11 As shown, the brewing mechanism includes a support, a brewing head 32, a brewing container 33, a slag pushing assembly 34, and a slag scraping assembly as described in any of the above embodiments. The brewing head 32 is fixed to the support. The brewing container 33 can move along the track 312 on the support and switch between an initial position (powder receiving position) and a brewing position. The slag pushing assembly 34 extends into the brewing container 33 and can move up and down along the brewing container 33 to push out the powder residue formed after brewing from the brewing container 33. The slag scraping assembly is provided on the support and is used to scrape the powder residue off the upper surface of the brewing container 33 and the upper surface of the slag pushing assembly 34 after the powder residue is pushed out of the brewing container 33 by the slag pushing assembly 34.

[0046] The brewing mechanism of this application embodiment includes a scraping component that has a good scraping effect and can reduce the residue of powder and residue on the upper surface of the brewing container 33 and the upper surface of the pusher component 34. Therefore, the coffee brewing effect of the brewing mechanism is better and more stable.

[0047] In some embodiments, such as Figure 4 As shown, the support of the brewing mechanism includes two opposing frame bodies 31, each with a slot 311. Each slot 311 includes a first groove with a circular cross-section and a second groove with a rectangular cross-section. The first and second grooves are connected to form an irregularly shaped (key-like) slot 311. Two irregularly shaped engaging portions 13 are provided on both sides of the fixing member 1. Each engaging portion 13 includes a cylindrical limiting post 131 and a rectangular rib 132. One side of the rectangular rib 132 is connected to the periphery of the limiting post 131. The limiting post 131 engages with the first groove, and the rectangular rib 132 engages with the second groove. The specially shaped slots 311 and the engaging portions 13 that mate with them facilitate convenient and stable installation of the fixing member 1 onto the support.

[0048] In some embodiments, such as Figures 1 to 10 As shown, a support rod 35 connects the two frame bodies 31, and the axis of the support rod 35 is parallel to the axis of the limiting post 131. The support rod 35 is positioned close to the scraping part 22 of the scraping component 2, with a certain gap between them. In the lateral movement direction of the brewing container 33, the support rod 35 is located downstream of the scraping part 22, and the axis of the support rod 35 is perpendicular to the lateral movement direction of the brewing container 33. The support rod 35 not only supports the two frame bodies 31, increasing the stability and structural strength of the entire support structure, but also supports and limits the scraping part 22 from the rear when it is scraping slag, preventing the flexible scraping part 22 from deforming too much, reducing the fit between the scraping part 22 and the upper surface of the brewing container 33 and the upper surface of the slag pushing component 34, thus affecting the scraping effect.

[0049] Understandably, the support rod 35 will not interfere with the movement of the brewing container 33. In the slag-pushing state, the support rod 35 is located above the upper surface of the brewing container 33, maintaining a certain distance from it.

[0050] The working process and working principle of the embodiments of this application will be described below with reference to the accompanying drawings: like Figure 5 and Figure 6As shown, when the brewing mechanism is initially started, the brewing container 33 is in the initial powder-receiving state. At this time, the brewing container 33 is located below the brewing head 32 and is offset from the brewing head 32. Moreover, the brewing head 32 and the brewing container 33 are located on both sides of the slag scraping assembly. At the same time, the upper end of the slag pushing assembly 34 is located at the bottom of the brewing container 33, making room inside the brewing container 33.

[0051] After the powder is collected by the brewing container 33, under the drive of the drive mechanism (not shown in the figure), the brewing container 33 moves laterally along the L-shaped track 312 on the support to directly below the brewing head 32, and then moves vertically upward to combine with the brewing head 32 to complete the powder pressing and brewing; at this time, the brewing head 32 and the brewing container 33 are located on the same side of the slag scraping assembly.

[0052] After brewing, the brewing container 33, driven by the drive mechanism, moves along the L-shaped track 312 back to its initial position to reset. During the reset process, the brewing container 33 first moves vertically downward along the track 312, disengaging from the brewing head 32. While the brewing container 33 moves vertically downward, the slag pushing component 34 does not move downward with it, allowing it to move vertically upward relative to the brewing container 33. When the upper surface of the slag pushing component 34 is flush with the upper surface of the brewing container 33, it completely pushes out the powder and slag formed after brewing from the brewing container 33. The powder and slag are then positioned on the upper surface of the slag pushing component 34. At this point, the brewing container 33 is at the bottom of the vertical section of the track 312 and is about to enter the horizontal section for horizontal movement. The slag scraping component is in the starting scraping state. (See [link to relevant documentation]). Figure 7 and Figure 8 ; The brewing container 33 moves laterally along the track 312, synchronously driving the slag pushing assembly 34. When the brewing container 33 and the slag pushing assembly 34 move laterally together, passing under the scraping part 22 of the scraping assembly, the bottom end of the scraping part 22 of the scraping assembly 2 can fit against the upper surface of the brewing container 33 and the upper surface of the slag pushing assembly 34. Therefore, the powder and slag are scraped away from the upper surface of the slag pushing assembly 34 and the brewing container 33, and enter the powder and slag chute 36 located below the brewing head 32, falling along the inclined powder and slag chute 36 into the slag receiving box (not shown in the figure). When the brewing container 33 moves laterally to the initial position, the scraping ends. See [reference needed]. Figure 9 and Figure 10 Waiting for the next brew.

[0053] It should be noted that the brewing head 32 and brewing container 33 cooperate in the brewing process, and the movement of brewing container 33 and push rod assembly can be achieved in the same way as the prior art, and this application will not elaborate on this.

[0054] 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.
