Description

Technical Field

[0001] The utility model relates to the technical field of coffee bean roasters, in particular to a coffee bean discharging mechanism of a coffee bean roaster. Background Art

[0002] Caffeine has the beneficial effects of refreshing, anti-depression, promoting digestion and reducing the incidence of gallstones, making it one of the most popular beverages in human society. People also like coffee more because it has additional flavors after being roasted. Coffee is a beverage made by grinding and brewing coffee beans after roasting. In addition to considering the variety and planting environment of coffee beans, strict consumers will even pay attention to the particle size of the ground powder, the brewing water temperature, the speed of the water flow, etc. Among them, the roasting time, temperature and heating method of coffee beans have the greatest impact on the flavor of coffee. Since the rich coffee aroma can only be smelled after roasting, there are currently coffee bean roasters specially used for drying coffee beans on the market. Coffee bean roasters are used to produce unique flavors and tastes after roasting raw coffee beans. Coffee bean roasters are generally equipped with a storage chamber for storing coffee beans. The coffee beans in the storage chamber are roasted using a heating device. The roasting process is to evaporate the water contained in the raw coffee beans at high temperature. When the water gradually evaporates, the coffee beans gradually caramelize and the color turns into coffee color.

[0003] The bean storage bins of household coffee roasters on the market are generally closed containers at the bottom. In order to take out the roasted coffee beans, it is necessary to use a tool to scoop them out from the top of the bean storage bin, or remove the bean storage bin from the roaster and turn the bean storage bin upside down to pour out the coffee beans. These two ways of outputting coffee beans are not conducive to actual operation and are inconvenient to use. Utility Model Content

[0045] like Figures 1 to 10 As shown, a bean discharging mechanism of a coffee bean roaster of the present embodiment comprises a fixed bracket 1 for being fixedly mounted on the coffee bean roaster, a bean discharging channel 2 is formed in the fixed bracket 1, the bean discharging channel 2 is connected to the bean storage chamber in the coffee bean roaster, and the bean discharging channel 2 extends obliquely downward in the fixed bracket 1, a bean inlet 22 and a bean outlet 21 are respectively formed at both ends of the bean discharging channel 2, the bean inlet 22 is connected to the inside of the bean storage chamber of the coffee bean roaster, specifically, a downwardly inclined inclined plate 12 is integrally formed at the bottom of the fixed bracket 1, and the inclined plate 12 extends obliquely downward from the bean inlet 22 to the bean outlet 21 at the bottom of the bean discharging channel 2, so that the coffee beans are automatically discharged outward along the inclined plate 12 in the bean discharging channel 2. In addition, an active valve 3 is installed on the bean outlet 21, and the active valve 3 is used to close the bean outlet 21 of the bean outlet channel 2, and a driven valve 4 is installed on the bean inlet 22, and the driven valve 4 is used to close the bean inlet 22 of the bean outlet channel 2. In the installation structure, the lower side of the active valve 3 is movably pivoted on the fixed bracket 1, and the bean outlet 21 of the bean outlet channel 2 can be opened after the active valve 3 is turned outward. Similarly, the upper side of the driven valve 4 is movably pivoted on the fixed bracket 1, and the bean inlet 22 of the bean outlet channel 2 can be opened after the driven valve 4 is turned outward. In addition, the active valve 3 and the driven valve 4 are also mutually linked to flip.

[0046] It can be understood that the bean discharging mechanism of the present embodiment is additionally provided with a fixed bracket 1 on the bean roaster, and a bean discharging channel 2 for communicating with the bean storage chamber of the bean roaster is provided on the fixed bracket 1, and then an active valve 3 and a driven valve 4 are respectively provided to close the bean outlet 21 and the bean inlet 22 of the bean discharging channel 2, and the active valve 3 and the driven valve 4 are respectively movably pivoted on the fixed bracket 1, so that they can be movably flipped on the fixed bracket 1, and the bean outlet 21 of the bean discharging channel 2 is opened by flipping the active valve 3 outwards, and the bean inlet 22 of the bean discharging channel 2 is also opened by flipping the driven valve 4 outwards. In addition, since the active valve 3 and the driven valve 4 are linked to each other and turned over, during operation, as long as the active valve 3 is controlled to turn outward, the driven valve 4 can be turned outward synchronously, and the bean inlet 22 and the bean outlet 21 of the bean outlet channel 2 are opened at the same time. The driven valve 4 is sleeved in a silicone sleeve 6, and a baffle 62 is provided on the side of the silicone sleeve 6 that is away from the bean outlet channel 2. When the driven valve 4 is turned outward, the baffle 62 on the back of the silicone sleeve 6 rotates outward synchronously to block the storage The coffee beans in the bean chamber do not overflow, and the coffee beans in the bean storage chamber enter from the bean inlet 22 of the bean outlet channel 2, slide obliquely downward along the bean outlet channel 2 to the bean outlet 21, and are output to the outside through the extension plate 31 of the active valve 4. That is to say, the utility model is provided with a bean outlet mechanism in the bean storage chamber connected to the inside of the roaster. When roasting is performed, the bean outlet mechanism is closed at the bean outlet of the bean storage chamber. When roasting is completed and the beans need to be output, the bean outlet of the bean storage chamber is opened by the bean outlet mechanism, so that the dried coffee beans can be automatically output. It can be seen that the structural scheme of the utility model can effectively solve the problem that the coffee beans in the roaster are not easy to output to the outside, making the bean outlet process of the roaster smoother and more convenient to use.

[0047] In one embodiment, specifically, a guide plate 42 is fixed to the front of the driven valve 4 (i.e., one side located inside the bean outlet passage 2), and the guide plate 42 extends from top to bottom, and the extended end of the guide plate 42 approaches the free flip end of the driven valve 4 (i.e., the lower end of the driven valve 4). On the other hand, a transmission frame 5 is movably installed in the bean outlet passage 2, and a first rotating shaft 51 and a second rotating shaft 52 are respectively provided on the front and rear sides of the transmission frame 5, and the first rotating shaft 51 is pivoted on the active valve 3 and approaches the free flip end of the active valve 3. It can also be understood that the first rotating shaft 51 and the rotation axis of the active valve 3 are at a certain distance to avoid the first rotating shaft 51 and the rotation axis of the active valve 3 being coaxial with each other, and the second rotating shaft 52 is pivoted in the guide rail of the guide plate 42 and can slide along the guide rail of the guide plate 42. In the closed state (i.e., the state in which the driven valve 4 is not flipped outward), the second rotating shaft 52 is at the upper end of the inner guide rail of the guide plate 42. In the process of opening the bean discharging channel 2, when the active valve 3 turns outward, the transmission frame 5 is driven to move outward through the first rotating shaft 51. In the process of the transmission frame 5 moving outward, the second rotating shaft 52 is driven to slide along the guide rail of the guide plate 42. During the sliding process, the second rotating shaft 52 slides along the guide rail of the guide plate 42 to the free turning end of the driven valve 4, and then the guide plate 42 and the driven valve 4 are also turned outward. It can be seen that the above structure can easily realize the mutual linkage between the active valve 3 and the driven valve 4, so that the driven valve 4 can turn back and forth with the active valve 3, so that the bean inlet 22 and the bean outlet 21 at both ends of the bean discharging channel 2 are opened and closed synchronously.

[0048] Specifically, the transmission frame 5 is provided with an escape opening 53, which is used to allow the bean outlet passage 2 to pass through, thereby preventing the transmission frame 5 from blocking the bean outlet passage 2 in the fixed bracket 1, and the structure is more reasonable and compact.

[0049] Regarding the specific structure of the active valve 3, the active valve 3 includes an extension plate 31, and the extension plate 31 is used to close the bean outlet 21 of the bean outlet channel 2. In addition, the extension plate 31 has limit vertical plates 32 integrally formed on the opposite sides. When the extension plate 31 is flipped outward with the active valve 3, the coffee beans are output from the bean outlet 21 of the bean outlet channel 2 to the surface of the extension plate 31, and output outward along the surface of the extension plate 31. The limit vertical plates 32 on both sides of the extension plate 31 can prevent the coffee beans from falling out to the two sides of the extension plate 31 during this process, so that the coffee beans can be more concentratedly output outward along the plate surface of the extension plate 31.

[0050] Furthermore, in order to ensure the sealing performance of the bean storage chamber inside the coffee roaster, a silicone sleeve 6 is further provided in the present embodiment, and the driven valve 4 is sleeved in the silicone sleeve 6. During assembly, the sealing surface on the back side of the silicone sleeve 6 (i.e., the plane away from the bean outlet passage 2) is sealed against the plane on the fixed bracket 1 for opening the bean inlet 22, so that the sealing surface on the back side of the silicone sleeve 6 can be sealed against the bean inlet 22 of the bean outlet passage 2, thereby improving the sealing performance of the bean storage chamber inside the coffee roaster, preventing the lower temperature air outside from passing through the bean outlet passage 2 during the process of heating and roasting the coffee beans in the coffee roaster to affect the internal roasting temperature of the bean storage chamber of the coffee roaster, and ensuring that the roasting effect of the coffee beans on the coffee roaster is not affected.

[0051] It should be noted that both the driven valve 4 and the silicone sleeve 6 have a certain thickness. Therefore, when the silicone sleeve 6 is turned over together with the driven valve 4, the bottom of the silicone sleeve 6 is easy to scrape the bottom wall of the bean outlet channel 2 (i.e., the surface of the inclined plate 12). Whenever the bottom of the silicone sleeve 6 scrapes the bottom wall of the bean outlet channel 2, the driven valve 4 will be stuck for a moment, which is not conducive to the service life of the movable structure. Therefore, in this embodiment, an elastic sealing sheet 61 protrudes downward from the bottom of the silicone sleeve 6, and the outer edge of the elastic sealing sheet 61 is aligned with the bottom wall of the bean outlet channel 2 (i.e., the inclined plate 12). The elastic sealing sheet 61 is thinner than the driven valve 4, so as to reduce the friction area between the bottom of the silicone sleeve 6 and the bottom wall of the bean outlet channel 2 (i.e., the surface of the inclined plate 12), and the elastic sealing sheet 61 can be elastically deformed when obstructed, so as to avoid obstacles smoothly. Therefore, when the silicone sleeve 6 is turned over together with the driven valve 4, the elastic sealing sheet 61 at the bottom of the silicone sleeve 6 scrapes the bottom wall of the bean outlet channel 2 without obviously causing the driven valve 4 to be stuck for a moment, thereby ensuring that the movable structure is not easily damaged.

[0052] In one embodiment, a baffle 62 is provided on the side of the silicone sleeve 6 that is away from the bean outlet channel 2. The baffle 62 extends upward in an inclined manner in the bean storage chamber of the roaster. During the flipping process of the driven valve 4, the baffle 62 is synchronously driven to swing downward and deflect toward the bean outlet 21. The baffle 62 of this structure can more easily push the coffee beans in the bean storage chamber into the bean outlet channel 2, so that the coffee beans can be more smoothly output through the bean outlet channel 2. In addition, when the driven valve 4 flips outward, the baffle 62 on the back of the silicone sleeve 6 rotates outward synchronously, which can also prevent the coffee beans in the bean storage chamber from overflowing. In actual use, the active valve 3 can also be manipulated to flip back and forth, and then the baffle 62 on the back of the driven valve 4 can be swung back and forth in the bean storage chamber of the roaster. This operation can more fully break up the coffee beans in the bean storage chamber, so that the output of the coffee beans is smoother.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
