Description

Technical Field

[0001] The utility model relates to the technical field of coffee grinders, in particular to a bean box assembly of a coffee grinder. Background Art

[0002] A coffee grinding device refers to a device for grinding coffee beans into powder, which is widely used in coffee machines or used in cooperation with coffee machines. Generally, the main body of the coffee grinder and the bean box for storage are separately arranged, and the bean box can be disassembled to facilitate the addition and replacement of coffee beans. A channel opening is provided at the bottom of the bean box, and the coffee beans in the bean box can be conveyed to the main body of the coffee grinder through the channel opening. Usually, a switchable lock is also provided at the channel opening to prevent leakage at the bottom of the bean box.

[0003] Chinese Patent CN203852247U discloses a coffee grinding device, including: a mounting seat arranged inside the coffee grinding device; a bean box, which includes a bottom cover provided with a through hole and a sliding door, and can be installed into or taken out of the mounting seat by the rotational movement of the bottom cover relative to the mounting seat; a transmission component for connecting the mounting seat and the sliding door. Among them, the transmission component can drive the sliding door to open the through hole when the bottom cover rotates relative to the mounting seat in the first direction, and drive the sliding door to close the through hole when the bottom cover rotates relative to the mounting seat in the opposite second direction. This device is used to realize the detachable connection between the bean box and the mounting seat, so that the bean box can be taken out of the coffee grinding device, thus facilitating the operations of quickly loading beans, adding beans or replacing beans.

[0004] Among them, the transmission component includes a receiving groove provided on the sliding door, a protruding member provided on the mounting seat for inserting into the receiving groove, and a track hole provided on the bottom cover of the bean box. The bean box is sequentially inserted into the wrapping part and the recessed part of the mounting seat. When the protruding member in the mounting seat passes through the track hole of the bottom cover and enters the receiving groove of the sliding door, the protrusion on the inner wall of the recessed part will enter the placement area of the clamping groove on the bottom cover. During the rotation process, the protruding member will act on the sliding door through the receiving groove to open the through hole. For the existing such coffee grinding device, the overall structure is relatively complex, and various protruding members, holes and slots are arranged on the bottom cover and the mounting seat. During assembly, mutual alignment and cooperation are required, and the forming and manufacturing are relatively difficult, which is not conducive to the popularization and application of the product.

[0005] Therefore, the existing technology still needs to be improved and developed. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a bean box assembly of a coffee grinder with a simple and compact structure and easy to disassemble in view of the defects and deficiencies of the existing technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A bean hopper assembly of the utility model includes a cylinder body, a base, and a locking structure. A bottom plate is provided at the lower end of the cylinder body, and a cylinder cover is provided at the upper end of the cylinder body. A bean outlet is formed on the bottom plate. The base is detachably connected to the main body of the coffee grinder, and the base is used to mount the cylinder body on the main body. Among them, the cylinder body is used to store coffee beans and supply coffee beans to the main body of the coffee grinder through the bean outlet. The cylinder cover seals the upper port of the cylinder body to close the inner cavity of the cylinder body and prevent external dust and water from contaminating the coffee beans in the cylinder body.

[0009] Furthermore, the locking structure includes a door seal and a guiding structure. The door seal is mounted on the bean outlet, and the door seal forms a sliding fit with the bottom plate through the guiding structure. The door seal closes or opens the bean outlet through horizontal sliding. It can be understood that the guiding structure generally refers to a device that can control the movement trajectory, such as a track structure. Preferably, the base is rotatably assembled at the bottom of the cylinder body, and a traction structure is provided between the door seal and the base. When the cylinder body rotates relative to the base, it will drive the door seal to rotate synchronously. Under the action of the traction structure, the door seal slides horizontally on the bean outlet.

[0010] Specifically, when the user holds the cylinder body and mounts the base on the coffee grinder, the cylinder body first drives the base to rotate clockwise by a certain angle to make the base paired and connected with the coffee grinder. Then continue to rotate the cylinder body to make it rotate relative to the base. At this time, the traction structure can drive the door seal to slide horizontally to open the bean outlet.

[0011] Conversely, the cylinder body first rotates counterclockwise by a certain angle, drives the door seal to slide horizontally through the traction structure to completely close the bean outlet, and then continues to rotate the cylinder body to drive the base to rotate relative to the coffee grinder to disassemble the base from the coffee grinder.

[0012] The utility model controls the sliding of the door seal through the two-stage rotation of the cylinder body and the cooperation of the traction structure to open or close the bean outlet. The operation is flexible and reliable, which can effectively prevent the leakage of residual coffee beans in the cylinder body. The structure is simple, easy to process, and the assembly is also very convenient.

[0013] According to the above scheme, the guiding structure includes a guiding seat and a connecting seat. The guiding seat is fixedly connected to the bottom plate, and the connecting seat is arranged below the guiding seat and fixedly connected to the bottom plate. A first through hole paired with the bean outlet is provided on the guiding seat, and a second through hole is provided on the connecting seat. The door seal is slidably inserted between the guiding seat and the connecting seat. Specifically, the cylinder body, the guiding seat, and the connecting seat are arranged in sequence from top to bottom. There is a gap between the guiding seat and the connecting seat, and this gap is used to arrange the door seal and enable the door seal to translate horizontally between the guiding seat and the connecting seat. The first through hole on the guiding seat serves as the structural extension of the bean outlet. The process of the door seal sliding along the guiding seat cooperates with the first through hole to open or close the bean outlet.

[0014] According to the above solution, buckles are provided on both sides of the door seal. The two buckles are respectively hung on the guide seats, so that the door seal can slide along the guide seats. The door seal and the buckles on both sides form a U-shaped integral structure. The door seal is arranged to fit the bottom surface of the guide seat, and the buckles on both sides are arranged to fit the two outer side walls of the guide seat, so that the door seal makes a linear reciprocating motion on the guide seat.

[0015] According to the above solution, a number of bolt columns are provided on the bottom plate of the door seal. The guide seat and the connecting seat are fixed to the number of bolt columns by bolts. It can be understood that the cylinder is used to store coffee beans, and the bottom of the cylinder usually needs to be designed in a funnel shape. Therefore, the bottom plate is a conical cylinder, and a bean outlet is provided at the bottom end of the conical cylinder. Further, the bolt columns are used to establish an installation surface on the conical bottom plate, and this installation surface is parallel to the horizontal plane, so as to facilitate the installation of the guide column, the connecting seat and the door seal.

[0016] According to the above solution, the traction structure includes a roller and a non-circular chute. The roller is rotatably installed on the door seal through a pin; a non-circular chute is provided on the base, and the roller is connected in cooperation with the non-circular chute. A locking device is provided at the first end of the non-circular chute. The non-circular chute is arranged around the inner cavity of the base. The distances from various positions on the non-circular chute to the center of the base are not equal. Further, the roller can roll along the non-circular chute. When the roller moves to different positions on the non-circular chute, the distance between the roller and the center of the base changes, driving the door seal to move horizontally along the guide seat.

[0017] According to the above solution, the locking device includes an arcuate elastic piece, and the arcuate elastic piece is fixedly connected to the base; a lock slot is provided on the arcuate elastic piece, and the lock slot is correspondingly arranged at the first end of the non-circular chute. The non-circular chute has a starting end and a terminating end. The first end of the non-circular chute is used as the starting end, and the second end of the non-circular chute is used as the terminating end. The distance from the non-circular chute at the starting end to the center of the base is the smallest, and the distance from the non-circular chute at the terminating end to the center of the base is the largest. The roller can slide between the starting end and the terminating end along the non-circular chute, and further drive the door seal to move horizontally on the guide seat. Correspondingly, when the roller is at the starting end of the non-circular chute, the door seal closes the bean outlet, and when the roller is at the terminating end of the non-circular chute, the door seal opens the bean outlet.

[0018] Further, the lock slot on the arcuate elastic piece corresponds to the starting end of the non-circular chute. When adding coffee beans, the cylinder first rotates a certain angle relative to the base. At this time, the roller on the door seal moves from the terminating end of the non-circular chute to the starting end and is caught in the lock slot. Continuing to rotate the cylinder can drive the base to separate it from the main body of the coffee grinder. At this time, the pressure provided by the arcuate elastic piece locks the roller, so that the door seal always closes the bean outlet, preventing coffee beans from leaking during the filling process.

[0019] Conversely, by rotating the cylinder body, the base can be first screwed into and connected to the coffee grinder. Continuing to rotate the cylinder body to overcome the locking of the bow-shaped elastic piece, the roller moves along the non-circular chute towards the termination end, and the door seal slides horizontally to open the coffee outlet.

[0020] When the above-mentioned cylinder body and base are installed and disassembled, the first rotation process of the cylinder body is used to control the assembly and disassembly of the base and the coffee grinder, and the second rotation process of the cylinder body controls the opening and closing of the door seal through the non-circular chute.

[0021] According to the above solution, the present utility model further includes a fixing ring. The lower end of the cylinder body is provided with a flange, and the upper end of the base is provided with a step; the fixing ring and the step are paired and connected to form a spacer groove therebetween, and the flange is inserted into the spacer groove so that the cylinder body is rotatably connected to the base. The fixing ring is sleeved outside the cylinder body. After the fixing ring and the base are fixedly connected by bolts, a spacer groove is formed between the inner edge of the fixing ring and the step, and the flange at the lower end of the cylinder body is inserted into the spacer groove, enabling the cylinder body to rotate relative to the base.

[0022] According to the above solution, a plurality of sliding buckle grooves are provided on the step. The sliding buckle grooves are formed at the step for mating with the interface of the coffee grinder. The base is inserted into the interface of the coffee grinder. By rotating a certain angle, the base can be connected or separated from the coffee grinder interface. The sliding buckle grooves are of a conventional structure and will not be elaborated here.

[0023] For the coffee bean box assembly of the present utility model, by rotating the second section of the cylinder body and cooperating with the traction structure to control the sliding of the door seal, the coffee outlet can be opened or closed. The operation is flexible and reliable, which can effectively prevent the leakage of residual coffee beans in the cylinder body. The structure is simple and easy to process, and the assembly is also very convenient. Description of the Drawings

[0030] The technical solution of the present utility model will be described below in conjunction with the accompanying drawings and embodiments.

[0031] As Figure 1 shown, a bean box assembly of a coffee grinder according to the present utility model includes a cylinder body 1, a base 2 and a locking structure. A bottom plate 11 is provided at the lower end of the cylinder body 1, a cylinder cover 12 is provided at the upper end of the cylinder body 1, and a bean outlet 13 is opened on the bottom plate 11. The base 2 is detachably connected to the main body of the coffee grinder, and the base 2 is used to mount the cylinder body 1 on the main body. Among them, the cylinder body 1 is used to store coffee beans and provide coffee beans to the main body of the coffee grinder through the bean outlet 13. The cylinder cover 12 covers the upper port of the cylinder body 1 to close the inner cavity of the cylinder body 1 and prevent external dust and water from contaminating the coffee beans in the cylinder body 1.

[0032] Furthermore, the locking structure includes a door seal 3 and a guiding structure. The door seal 3 is covered on the bean outlet 13, and the door seal 3 forms a sliding fit with the bottom plate 11 through the guiding structure. The door seal 3 closes or opens the bean outlet 13 through horizontal sliding. It can be understood that the guiding structure generally refers to a device that can control the movement trajectory, such as a track structure. Preferably, the base 2 is rotatably assembled at the bottom of the cylinder body 1, and a traction structure is provided between the door seal 3 and the base 2. When the cylinder body 1 rotates relative to the base 2, the door seal 3 will be driven to rotate synchronously, and under the action of the traction structure, the door seal 3 slides horizontally on the bean outlet 13.

[0033] Specifically, when the user holds the cylinder body 1 and installs the base 2 on the coffee grinder, the cylinder body 1 first drives the base 2 to rotate clockwise by a certain angle to make the base 2 paired and connected with the coffee grinder, and then continues to rotate the cylinder body 1 to make it rotate relative to the base 2. At this time, the traction structure can drive the door seal 3 to slide horizontally to open the bean outlet 13.

[0034] Conversely, the cylinder body 1 first rotates counterclockwise by a certain angle, drives the door seal 3 to slide horizontally through the traction structure to completely close the bean outlet 13, and then continues to rotate the cylinder body 1 to drive the base 2 to rotate relative to the coffee grinder to disassemble the base 2 from the coffee grinder.

[0035] The utility model controls the sliding of the door seal 3 through the two-stage rotation of the cylinder body 1 and cooperates with the traction structure to open or close the bean outlet 13. The operation is flexible and reliable, which can effectively prevent the leakage of residual coffee beans in the cylinder body 1. The structure is simple and easy to process, and the assembly is also very convenient.

[0036] The guiding structure includes a guiding seat 31 and a connecting seat 32. The guiding seat 31 is fixedly connected to the bottom plate 11, and the connecting seat 32 is arranged below the guiding seat 31 and fixedly connected to the bottom plate 11. A first through hole 33 paired with the bean outlet 13 is provided on the guiding seat 31, and a second through hole 34 is provided on the connecting seat 32. The door seal 3 is slidably arranged between the guiding seat 31 and the connecting seat 32. Specifically, the cylinder body 1, the guiding seat 31, and the connecting seat 32 are arranged in sequence from top to bottom. There is a gap between the guiding seat 31 and the connecting seat 32, which is used to arrange the door seal 3 and enable the door seal 3 to horizontally translate between the guiding seat 31 and the connecting seat 32. The first through hole 33 on the guiding seat 31 serves as the structural extension of the bean outlet 13. During the process of the door seal 3 sliding along the guiding seat 31, the bean outlet 13 is opened or closed in cooperation with the first through hole 33.

[0037] Clamping plates 35 are provided on both sides of the door seal 3, and the two clamping plates 35 are respectively hooked on the guiding seat 31, so that the door seal 3 can slide along the guiding seat 31. The door seal 3 and the clamping plates 35 on both sides form a U-shaped integral structure. The door seal 3 is arranged to fit the bottom surface of the guiding seat 31, and the clamping plates 35 on both sides are arranged to fit the two outer side walls of the guiding seat 31, so that the door seal 3 makes a linear reciprocating motion on the guiding seat 31.

[0038] A plurality of bolt columns 15 are provided on the bottom plate 11 of the door seal 3, and the guiding seat 31 and the connecting seat 32 are fixed on the plurality of bolt columns 15 by bolts. It can be understood that the cylinder body 1 is used to store coffee beans, and the bottom of the cylinder body 1 usually needs to be designed in a funnel shape. Therefore, the bottom plate 11 is a conical cylinder, and the bean outlet 13 is arranged at the bottom end of the conical cylinder. Further, the bolt columns 15 are used to establish an installation surface on the conical bottom plate 11, and this installation surface is parallel to the horizontal plane, so as to facilitate the installation of the guiding column, the connecting seat 32, and the door seal 3.

[0039] The traction structure includes a roller 36 and a non-circular chute 21. The roller 36 is rotatably installed on the door seal 3 through a pin; a non-circular chute 21 is provided on the base 2, and the roller 36 is cooperatively connected with the non-circular chute 21. A locking device is provided at the first end of the non-circular chute 21. The non-circular chute 21 is arranged around the inner cavity of the base 2, and the distance between each position on the non-circular chute 21 and the center of the base 2 is not equal. Further, the roller 36 can roll along the non-circular chute 21. When the roller 36 moves to different positions on the non-circular chute 21, the distance between the roller 36 and the center of the base 2 changes, driving the door seal 3 to horizontally move along the guiding seat 31.

[0040] The locking device includes an arcuate elastic piece 22, and the arcuate elastic piece 22 is fixedly connected to the base 2; a locking groove 23 is provided on the arcuate elastic piece 22, and the locking groove 23 is correspondingly arranged at the first end of the non-circular sliding groove 21. The non-circular sliding groove 21 has a starting end and an ending end. The first end of the non-circular sliding groove 21 is used as the starting end, and the second end of the non-circular sliding groove 21 is used as the ending end. The distance between the starting end of the non-circular sliding groove 21 and the center of the base 2 is the smallest, and the distance between the ending end of the non-circular sliding groove 21 and the center of the base 2 is the largest. The roller 36 can slide along the non-circular sliding groove 21 between the starting end and the ending end, thereby driving the door seal 3 to move laterally on the guide seat 31. Correspondingly, when the roller 36 is at the starting end of the non-circular sliding groove 21, the door seal 3 closes the bean outlet 13, and when the roller 36 is at the ending end of the non-circular sliding groove 21, the door seal 3 opens the bean outlet 13.

[0041] Further, the locking groove 23 on the arcuate elastic piece 22 corresponds to the starting end of the non-circular sliding groove 21. When adding coffee beans, the cylinder body 1 first rotates a certain angle relative to the base 2. At this time, the roller 36 on the door seal 3 moves from the ending end of the non-circular sliding groove 21 to the starting end and is stuck in the locking groove 23. Continuing to rotate the cylinder body 1 can drive the base 2 to separate it from the coffee grinder main body. At this time, the pressure provided by the arcuate elastic piece 22 locks the roller 36, so that the door seal 3 always closes the bean outlet 13 to prevent coffee beans from leaking during the filling process.

[0042] On the contrary, by rotating the cylinder body 1 first, the base 2 can be screwed into and connected to the coffee grinder. Continuing to rotate the cylinder body 1 to overcome the locking of the arcuate elastic piece 22, the roller 36 moves along the non-circular sliding groove 21 towards the ending end, and the door seal 3 slides laterally to open the bean outlet 13.

[0043] When the above-mentioned cylinder body 1 and the base 2 are installed and disassembled, the first rotation process of the cylinder body 1 is used to control the assembly and disassembly of the base 2 and the coffee grinder, and the second rotation process of the cylinder body 1 controls the opening and closing of the door seal 3 through the non-circular sliding groove 21.

[0044] The utility model further includes a fixing ring 4. The lower end of the cylinder body 1 is provided with a flange 14, and the upper end of the base 2 is provided with a step 24; the fixing ring 4 and the step 24 are paired and connected to form a spacing groove therebetween, and the flange 14 passes through the spacing groove so that the cylinder body 1 is rotatably connected to the base 2. The fixing ring 4 is sleeved on the outside of the cylinder body 1. After the fixing ring 4 and the base 2 are fixedly connected by bolts, a spacing groove is formed between the inner edge of the fixing ring 4 and the step 24, and the flange 14 at the lower end of the cylinder body 1 passes through the spacing groove, so that the cylinder body 1 can rotate relative to the base 2.

[0045] A number of sliding buckle grooves 25 are provided on the step 24. The sliding buckle grooves 25 are formed at the step 24 and are used to mate with the interface of the coffee grinder. The base 2 is inserted into the interface of the coffee grinder. By rotating a certain angle, the base 2 can be connected to or separated from the interface of the coffee grinder. The sliding buckle groove 25 is a conventional structure, so it will not be elaborated here.
