Hull door support, hull door and hull door assembly

Abstract

This utility model relates to a coffee grinder, specifically designing a coffee hopper lid support, a coffee hopper lid, and a coffee hopper lid assembly. The coffee hopper lid support has a coffee bean inlet channel and is fitted with the coffee hopper lid. A rotating structure is provided on the coffee hopper lid support, allowing the coffee hopper lid to rotate relative to the support. When the coffee hopper lid rotates from the starting position to the ending position, the rotating structure moves the lid away from the support, opening the coffee bean inlet channel. When the coffee hopper lid rotates from the ending position to the starting position, the lid moves close to the support, closing the coffee bean inlet channel. Compared to existing technologies, rotating the coffee hopper lid not only easily opens and closes the coffee bean inlet channel, but also prevents negative pressure from forming inside the coffee hopper due to the opening of the channel, effectively preventing coffee powder from flying out of the channel and contaminating the grinder's exterior and the external environment.

Description

Technical Field

[0001] The present invention relates to a coffee grinder, and specifically designs a coffee hopper cover bracket, a coffee hopper cover, and a coffee hopper cover assembly. Background Technology

[0002] Portable coffee grinders, as portable devices that grind coffee beans into coffee powder, are small and easy to carry, allowing users to enjoy freshly ground coffee anytime, anywhere. However, the inventors discovered that the opening method of the bean hopper in existing portable coffee grinders is generally a top-and-bottom plug-and-play method. To ensure the sealing performance of the grinder during grinding, the bean hopper lid is usually tightly fitted to the bean hopper after it is closed. This makes it relatively difficult to open or close the bean hopper lid. Furthermore, when opening the bean hopper, the coffee powder inside can easily create negative pressure due to the removal of the bean hopper lid, causing the coffee powder to fly out of the bean hopper. This not only contaminates the outer surface of the grinder but also pollutes the external environment. Utility Model Content

[0003] The purpose of this utility model is to design a bean hopper cover bracket, bean hopper cover, and bean hopper cover assembly, which can not only easily open and close the bean inlet channel, but also effectively prevent coffee powder from flying out of the bean inlet channel due to negative pressure when the bean inlet channel is opened, thereby avoiding pollution to the outer surface of the coffee machine and the external environment.

[0004] To achieve the above objectives, an embodiment of the present invention provides a bean hopper cover bracket, which has a bean inlet channel, is used to be fitted with a bean hopper cover, and is provided with a rotating structure.

[0005] The rotating structure allows the bean hopper cover to rotate relative to the bean hopper cover bracket, and when the bean hopper cover rotates from the starting position to the ending position, it causes the cover plate of the bean hopper cover to move away from the bean hopper cover bracket and opens the bean inlet channel.

[0006] The rotating structure is also used to make the cover plate of the bean hopper close to the bean hopper cover bracket and close the bean inlet channel when the bean hopper cover rotates from the end position to the start position.

[0007] In addition, an embodiment of this utility model also provides a bean hopper cover, which is used to fit onto the bean hopper cover bracket described above, and the bean hopper cover is rotatable relative to the bean hopper cover bracket. The bean hopper cover includes:

[0008] The cover body is fitted onto the bean hopper cover bracket and is rotatably connected to the bean hopper cover bracket; the cover body has a top side and a bottom side opposite to the top side along its axial direction;

[0009] A cover plate is disposed on the top side of the cover body; the cover plate is used to move away from the bean hopper cover bracket and open the bean inlet channel when the cover body rotates from the starting position to the ending position; the cover plate is also used to move close to the bean hopper cover bracket and close the bean inlet channel when the cover body rotates from the ending position to the starting position.

[0010] In addition, embodiments of this utility model also provide a bean hopper cover assembly, comprising:

[0011] The bean hopper cover bracket as described above;

[0012] The bean hopper cover as described above.

[0013] Compared to existing technologies, the embodiments of this utility model feature a bean hopper lid support with a bean inlet channel. The support also incorporates a rotating structure that can be fitted onto the bean hopper lid. This allows the bean hopper lid support to not only rotate relative to the support using the rotating structure, but also to guide the rotation of the lid. As the lid rotates from the starting position to the ending position, the lid plate moves away from the support, opening the bean inlet channel. Conversely, as the lid rotates from the ending position to the starting position, the lid plate moves back towards the support, closing the bean inlet channel. Therefore, rotating the lid easily opens and closes the bean inlet channel without creating negative pressure inside, effectively preventing coffee powder from flying out of the channel and contaminating the grinder's surface and the environment.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0022] Example 1

[0023] The first embodiment of this utility model relates to a bean hopper cover bracket, such as... Figure 1 and Figure 3 As shown, the bean hopper cover bracket 1 has a bean inlet channel 11, and, combined with Figure 4 As shown, the bean hopper cover bracket 1 is used to be fitted with the bean hopper cover 2, and at the same time, as Figure 1 and Figure 2 As shown, a rotating structure 12 is provided on the bean hopper cover support 1, which allows the bean hopper cover 2 to rotate relative to the bean hopper cover support 1.

[0024] In addition, such as Figure 4 and Figure 6 As shown, the rotating structure 12 is used to move the cover plate 21 of the bean hopper cover 2 away from the bean hopper cover bracket 1 and open the bean inlet channel 11 when the bean hopper cover 2 rotates from the starting position to the ending position. Secondly, the rotating structure is also used to move the cover plate 21 of the bean hopper cover 2 close to the bean hopper cover bracket 1 and close the bean inlet channel 11 when the bean hopper cover 2 rotates from the ending position to the starting position.

[0025] It is easy to see from the above that, since the bean hopper cover bracket 1 has a bean inlet channel 11 and a rotating structure 12 is provided on the bean hopper cover bracket 1, which can be sleeved on the bean hopper cover, the bean hopper cover bracket 1 can not only use the rotating structure 12 to make the bean hopper cover 2 rotate relative to the bean hopper cover bracket 1, but also use the rotating structure 12 to guide the rotation of the bean hopper cover 2. Thus, when the bean hopper cover 2 rotates from the starting position to the ending position, the cover plate 21 of the bean hopper cover 2 can move away from the bean hopper cover bracket 1, and the cover plate 21 can open the bean inlet channel 11. When the bean hopper cover 2 rotates from the ending position to the starting position, the cover plate 21 of the bean hopper cover 2 can come close to the bean hopper cover bracket 1, and the cover plate 21 can close the bean inlet channel 11. It is easy to see that by rotating the bean hopper cover 2, not only can the bean feeding channel 11 be easily opened and closed, but the coffee powder inside will not generate negative pressure due to the opening of the bean feeding channel 11, thereby effectively preventing the coffee powder from flying out of the bean feeding channel 11 and effectively avoiding the coffee powder from contaminating the outer surface of the grinder and the external environment.

[0026] In other embodiments, the direction in which the bean hopper lid 2 rotates from the starting position to the ending position is counterclockwise, while the direction in which the bean hopper lid 1 rotates from the ending position to the starting position is clockwise. That is, rotating the bean hopper lid 2 counterclockwise opens the bean inlet channel 11, and rotating the bean hopper lid 2 clockwise closes the bean inlet channel 11. In other words, the rotation direction of the bean hopper lid 2 when opening and closing the bean inlet channel 11 is consistent with the rotation direction of the water bottle cap. Therefore, the way the bean hopper lid 2 opens and closes the bean inlet channel 11 is more in line with the user's daily usage habits, thereby reducing the user's learning cost and further facilitating the user's operation of the bean hopper lid 2.

[0027] Furthermore, it is worth noting that in some embodiments, the rotating structure 12 is also used to engage the bean hopper cover 2 with the bean hopper cover bracket 1 along its axial direction when the bean hopper cover 2 rotates to the end position. This allows the bean hopper cover 2 to be fixed in place by the engagement with the bean hopper cover bracket 1 after the bean inlet channel 11 is opened, preventing the bean hopper cover 2 from being removed from the bean hopper cover bracket 1. However, as a preferred embodiment, in some embodiments, the rotating structure 12 is also used to allow the bean hopper cover 2 to rotate from the starting position away from the end position. When the bean hopper cover 2 rotates to a preset position, the rotating structure 12 also allows the bean hopper cover 2 to be separated from the bean hopper cover bracket 1 along its axial direction. It is easy to see that after the bean inlet channel 11 is closed, the bean hopper cover 2 can be removed from the bean hopper cover bracket 1 by continuing to rotate away from the end position to the preset position. This facilitates cleaning of the bean hopper cover 2 and the bean hopper cover bracket 1 by the user and effectively prevents bacterial growth.

[0028] In addition, it should be noted that in some other embodiments, the rotating structure 12 is also used to allow the cover plate 21 of the bean hopper cover 2 to move away from the bean hopper cover bracket 1 when the bean hopper cover 2 rotates from the starting position to the preset position. That is, at this time the bean hopper cover 2 is in the state of opening the bean inlet channel 11, so that the bean hopper cover 2 can be more easily removed from the bean hopper cover bracket 1 by the user.

[0029] Furthermore, it is worth mentioning that, in order to guide the rotation of the bean hopper lid 2 by the rotating structure 12, so that the bean hopper lid 2 can also move linearly along its own axis while rotating, in some embodiments, such as Figure 1 and Figure 2 As shown, the rotating structure 12 includes at least one sliding groove 121, and the number of sliding grooves 121 is the same as the number of positioning elements 22 on the bean hopper cover 2, and they correspond uniquely. Furthermore, when multiple sliding grooves 121 are provided, each sliding groove 121 can be arranged circumferentially around the bean hopper cover support 1. Simultaneously, each sliding groove 121 is used to be embedded in and slidably engaged with its uniquely corresponding positioning element 22. Each sliding groove 121 also guides the rotation of the bean hopper cover 2, allowing the bean hopper cover 2 to move linearly along its axial direction.

[0030] Specifically, in some embodiments, such as Figure 2 As shown, each groove 121 includes: a first inclined groove section 1211, an upper horizontal groove section 1212, a lower horizontal groove section 1213, a second inclined groove section 1214, and a vertical groove section 1215. The first inclined groove section 1211 has a head and a tail section away from the head. This first inclined groove section 1211 guides the uniquely corresponding positioning member 22 when the bean hopper cover 2 rotates from the starting position towards the end position, allowing the cover plate 21 of the bean hopper cover 2 to gradually move away from the bean hopper cover support 1. Secondly, as... Figure 2 As shown, the upper horizontal groove segment 1212 is connected to the head of the first inclined groove segment 1211, and the upper horizontal groove segment 1212 is used to engage with the uniquely corresponding positioning member 22 along its axial direction when the bean hopper cover 2 rotates to the end position. Additionally, as... Figure 2 As shown, the lower horizontal groove segment 1213 is connected to the root of the first inclined groove segment 1211, and this lower horizontal groove segment 1213 is used to engage with the uniquely corresponding positioning member 22 along its axial direction when the bean hopper cover 2 rotates to the starting position. Furthermore, as... Figure 2 As shown, the second inclined groove segment 1214 is connected to the end of the lower horizontal groove segment 1213 that is away from the first inclined groove segment 1211. This second inclined groove segment 1214 guides the uniquely corresponding positioning member 22 when the bean hopper cover 2 rotates from the starting position towards the preset position, causing the cover plate 21 of the bean hopper cover 2 to gradually move away from the bean hopper cover support 1. Finally, as... Figure 2As shown, the vertical groove section 1215 is connected to the end of the second inclined groove section 1214 away from the end connected to the first inclined groove section 1211. The vertical groove section 1215 is used to separate from the uniquely corresponding positioning member 22 along its axial direction when the bean hopper cover 2 is rotated to the preset position.

[0031] It is easy to see that when the bean hopper cover 2 rotates, the first inclined groove segment 1211 guides and engages with the uniquely corresponding positioning element 22, allowing the bean hopper cover 2 to rotate between the starting position and the ending position, thereby enabling the cover plate 21 to open and close the bean inlet channel 11. The second inclined groove segment 1214 guides and engages with the uniquely corresponding positioning element 22, allowing the bean hopper cover 2 to rotate between the starting position and the preset position. When the bean hopper cover 2 rotates to the preset position, it can be installed and removed from the bean hopper cover bracket 1 along its axial direction by guiding and engaging with the uniquely corresponding vertical groove segment 1215.

[0032] Additionally, as a preferred embodiment, in other embodiments, such as Figure 2 As shown, at least one side of the upper horizontal groove section 1212 has a portion of its groove wall protruding to form a snap-fit ​​protrusion 1216. Each snap-fit ​​protrusion 1216 is used to position the positioning member 22 on the upper horizontal groove section 1212 when the bean hopper cover 2 rotates to the stop position. Specifically, in some embodiments, such as... Figure 2 As shown, a snap-fit ​​protrusion 1216 can be provided, which is formed by protruding from one side of the groove wall of the upper horizontal groove segment 1212. The snap-fit ​​protrusion 1216 is set towards the root of the upper horizontal groove segment 1212, so that there is a narrow gap between the snap-fit ​​protrusion 1216 and the other side of the groove wall of the upper horizontal groove segment 1212. At the same time, a snap-fit ​​position for the positioning member 22 is formed between the snap-fit ​​protrusion 1216 and the root of the upper horizontal groove segment 1212. Therefore, when the bean hopper cover 2 rotates from the starting position to the ending position, the positioning member 22 on the bean hopper cover 2 can forcibly pass through the snap-fit ​​protrusion 1216 and reach the root of the upper horizontal groove segment 1212. At this time, the positioning member 22 can be snap-fitted and positioned in the position formed between the snap-fit ​​protrusion 1216 and the root of the upper horizontal groove segment 1212, so that the bean hopper cover 2 can be positioned in the ending position, thereby ensuring that the user can stably feed beans through the bean feeding channel 11.

[0033] Similarly, in order to stably position the bean hopper cover 2 at the starting position, in other embodiments, such as Figure 2As shown, at least one side of the first inclined groove section 1211 has a portion of its groove wall protruding to form a first engaging protrusion 1217. Simultaneously, at least one side of the second inclined groove section 1214 has a portion of its groove wall protruding to form a second engaging protrusion 1218. Both the first engaging protrusion 1217 and the second engaging protrusion 1218 are positioned towards the lower horizontal groove section 1213. The first engaging protrusion 1217 and the second engaging protrusion 1218 are used to position the positioning member 22 in the lower horizontal groove section 1213 when the bean hopper cover 2 rotates to the starting position. Specifically, in some embodiments, such as... Figure 2 As shown, one of each of the first engaging protrusion 1217 and the second engaging protrusion 1218 can be provided. The first engaging protrusion 1217 is formed by protruding from one side of the groove wall of the first inclined groove segment 1211, while the second engaging protrusion 1218 is formed by protruding from one side of the groove wall of the second inclined groove segment 1214. Both the first engaging protrusion 1217 and the second engaging protrusion 1218 are positioned towards the lower horizontal groove segment 1213. For example, the first engaging protrusion 1217 can be located at the head of the first inclined groove segment 1211, and the second engaging protrusion 1218 can be located at the root of the second inclined groove segment 1214. Therefore, the head of the first inclined groove segment 1211 and the root of the second inclined groove segment 1214 have a narrow gap, so that another locking position for engaging the positioning member 22 is formed between the first engaging protrusion 1217 and the second engaging protrusion 1218. Therefore, when the bean hopper cover 2 rotates from the starting position to the preset position, the positioning member 22 on the bean hopper cover 2 can forcibly pass through the first locking protrusion 1217 and enter the lower horizontal groove section 1213. At this time, the positioning member 22 can be locked and positioned in the lower horizontal groove section 1213 by another locking position formed between the first locking protrusion 1217 and the second locking protrusion 1218, so that the bean hopper cover 2 can be positioned in the starting position, so that the bean hopper cover 2 can stably close the bean inlet channel 11. When the bean hopper cover 2 rotates from the preset position to the starting position, the positioning part 22 on the bean hopper cover 2 can be forcibly passed through the second locking protrusion 1218 and enter the lower horizontal groove section 1213. At this time, the positioning part 22 can also be locked and positioned in the lower horizontal groove section 1213 by another locking position formed between the second locking protrusion 1218 and the first locking protrusion 1217, so that the bean hopper cover 2 can also be positioned in the starting position, and the bean hopper cover 2 can also stably achieve the closure of the bean inlet channel 11.

[0034] Furthermore, it is worth mentioning that, in order to further ensure and improve the positioning performance of the bean hopper cover 2 in the starting position, the length of the lower horizontal groove section 1213 should be controlled as much as possible. That is, the length of the lower horizontal groove section 1213 should be as equal to or slightly larger than the cross-sectional diameter of the positioning member 22 as possible. This allows the positioning member 22 to abut against the first locking protrusion 1217 and the second locking protrusion 1218 respectively when it enters the lower horizontal groove section 1213, so that the positioning member 22 cannot move around the circumference of the bean hopper cover 2 in the lower horizontal groove section 1213, thereby ensuring the positioning performance of the bean hopper cover 2 when it is rotated to the starting position.

[0035] Example 2

[0036] Embodiment 2 of this utility model relates to a bean hopper cover, such as... Figure 4 , Figure 5 and Figure 6 As shown, the bean hopper lid 2 is used to fit onto the bean hopper lid bracket 1 as described in Embodiment 1. Simultaneously, the bean hopper lid 2 is rotatable relative to the bean hopper lid bracket 1, and as... Figure 4 and 6 As shown, the bean hopper cover 2 includes: a cover body 23 and a cover plate 21.

[0037] Among them, such as Figure 6 As shown, the cover body 23 is sleeved on the bean hopper cover bracket 1 and rotatably connected to the bean hopper cover bracket 1. The cover body 23 has a top side 231 and a bottom side 232 opposite to the top side 231 along its axial direction. Additionally, a cover plate 21 is disposed on the top side 231 of the cover body 23. The cover plate 21 is used to move away from the bean hopper cover bracket 1 when the cover body 23 rotates from the starting position to the ending position, allowing the cover plate 21 to open the bean inlet channel 11. Furthermore, the cover plate 21 is also used to move closer to the bean hopper cover bracket 1 when the cover body 23 rotates from the ending position to the starting position, allowing the cover plate 21 to close the bean inlet channel 11.

[0038] It is easy to see from the above that the bean hopper cover 2 includes a cover body 23 and a cover plate 21. The cover body 23 of the bean hopper cover 2 can be sleeved on the bean hopper cover bracket 1 and can rotate relative to the bean hopper cover bracket 1 using the rotating structure 12 on the bean hopper cover bracket 1. While the cover body 23 rotates, the cover plate 21 can also move linearly relative to the bean hopper cover bracket 1 along its axis using the rotating structure 12. That is, when the cover body 23 rotates from the starting position to the ending position, the cover plate 21 can move away from the bean hopper cover bracket 1, so that the cover plate 21 can open the bean inlet channel 11 of the bean hopper cover bracket 1. Conversely, when the cover body 23 rotates from the ending position to the starting position, the cover plate 21 can move closer to the bean hopper cover bracket 1, so that the cover plate 21 can close the bean inlet channel 11 of the bean hopper cover bracket 1. It is easy to see that by rotating the bean hopper cover 2, not only can the bean feeding channel 11 be easily opened and closed, but the coffee powder inside the grinder will not generate negative pressure due to the opening of the bean feeding channel 11, thereby effectively preventing the coffee powder from flying out of the bean feeding channel 11 and effectively avoiding the coffee powder from contaminating the outer surface of the grinder and the external environment.

[0039] Specifically, in some embodiments, such as Figure 6 As shown, the cover body 23 has an inner side 233 and an outer side 234 opposite to the inner side 233 along its axis. At least one positioning element 22 is provided on the inner side 233. The number of positioning elements 22 is the same as the number of sliding grooves 121 on the bean hopper cover bracket 1, and they correspond uniquely. Furthermore, when multiple positioning elements 22 are provided, such as... Figure 1 and Figure 4 As shown, each positioning element 22 is arranged around the axis of the cover body 23, and each positioning element 22 is used to embed into a unique corresponding slide groove 121 and slide in cooperation with the unique corresponding slide groove 121. In addition, each positioning element 22 is also used to guide the bean hopper cover 2 when it rotates, so that the bean hopper cover 2 can move linearly along its axis.

[0040] Furthermore, it is worth mentioning that in some embodiments, each positioning member 22 may be formed by a portion of the inner side 233 of the cover 23 protruding away from the outer side 234. However, as an alternative, in other embodiments, such as Figure 1 As shown, each positioning element 22 can also be detachably connected to the cover body 23. For example, the positioning element 22 can be threadedly connected to the cover body 23. To achieve the threaded connection between the positioning element 22 and the cover body 23, such as... Figure 4As shown, the positioning member 22 includes: a limiting part 221 and an external threaded section 222 connected to the limiting part 221. The outer diameter of the external threaded section 222 is larger than the outer diameter of the limiting part 221, so that the overall cross-sectional shape of the positioning member 22 is T-shaped. A plurality of mounting holes 24 are provided around the circumference of the cover body 23 corresponding to each positioning member 22, and the overall cross-section of each mounting hole 24 is a T-shaped structure. That is, the mounting hole 24 includes: a through hole section and an internal threaded section. The through hole section 24 allows the limiting part 221 of the positioning member 22 to pass through, and allows the limiting part 221 to protrude from the inner side 233 of the cover body 23. The internal threaded section can be screwed into the external threaded section 222 of the positioning member 22, so that each positioning member 22 can be fixed on the cover body 23. Furthermore, in order to improve the rotational performance of the bean hopper lid 2 when rotating relative to the bean hopper lid support 1, in some embodiments, the surface of the limiting part 221 of each positioning member 22 can be an arc surface or a spherical surface, so that when the limiting part 221 is embedded in the slide groove 121, the limiting part 221 can make point contact with each groove wall of the slide groove 121, thereby reducing the frictional resistance caused by each groove wall of the slide groove 121 to the positioning member 22 when the bean hopper lid 2 rotates, making it easier for the user to operate the rotation of the bean hopper lid 2.

[0041] Example 3

[0042] Embodiment 3 of this utility model relates to a bean hopper cover assembly, such as... Figure 1 and Figure 7 As shown, it includes: the bean hopper cover bracket 1 as described in Embodiment 1, and the bean hopper cover 2 as described in Embodiment 2.

[0043] Those skilled in the art will understand that the above embodiments are specific implementations of the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
