Description

Technical Field

[0001] The utility model relates to the field of bean grinding equipment, in particular to a bean box mechanism and a bean grinding device. Background Art

[0002] The existing coffee bean box generally does not have a closing mechanism at the bottom. Since the amount of coffee beans in the bean box is not always just right, when the user removes the bean box, the coffee beans remaining in the bean box will fall out from the opening. During use, the bean box cannot be directly taken out of the coffee machine to add coffee beans. Only when the coffee beans in the bean box are used up can the bean box be removed from the coffee machine, which reduces the operating efficiency. If the user does not want to waste time, the user can only empty the coffee beans in the bean box assembly by turning the coffee machine over, and then remove the bean box, which is also very inconvenient. Utility Model Content

[0003] In order to overcome the deficiencies in the prior art, the utility model provides a bean box mechanism, which realizes opening and closing of the bean outlet by setting an opening and closing door structure, and at the same time, a first opening and closing door limiting structure and a second opening and closing door limiting structure are provided to limit the opening and closing door structure from opening the bean outlet after the bean box is removed from the bean box seat; and when the bean box is installed on the bean box seat, the first opening and closing door limiting structure and the second opening and closing door limiting structure are unlocked by an unlocking structure, which is easy to operate and reasonably designed. The utility model also provides a bean grinding device.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A bean box mechanism comprises a bean box seat, and a bean box detachably mounted on the bean box seat; the bean box is provided with a bean outlet for discharging beans, and an opening and closing door structure matching the bean outlet is movably arranged in the bean box to control the opening and closing of the bean outlet; a first opening and closing door limiting structure is arranged on the bean box, and a second opening and closing door limiting structure is arranged on the opening and closing door structure to lock and cooperate with the first opening and closing door limiting structure when the opening and closing door structure closes the bean outlet to limit the movement of the opening and closing door structure; the bean box seat is provided with an unlocking structure for unlocking the first opening and closing door limiting structure and the second opening and closing door limiting structure when the bean box is installed on the bean box seat.

[0006] With the above structure, when in use, the user can operate the opening and closing door structure to open and close the bean outlet, so that the user can take out the bean box from the bean box seat when there are still coffee beans in the bean box; and when the user takes out the bean box from the bean box seat with the opening and closing door structure closing the bean outlet, the first opening and closing door limiting structure and the second opening and closing door limiting structure are locked and matched to limit the movement of the opening and closing door structure to prevent the bean outlet from being accidentally opened;

[0007] When the user installs the bean box on the bean box seat, the unlocking structure on the bean box seat will act on the first opening and closing door limiting structure and / or the second opening and closing door limiting structure, so that the first opening and closing door limiting structure and the second opening and closing door limiting structure are unlocked, and the restriction on the movement of the opening and closing door structure is cancelled. At this time, the user can operate the opening and closing door structure to make the opening and closing door structure move to open the bean outlet; when the user wants to remove the bean box from the bean box seat, he only needs to operate the opening and closing door structure to close the bean outlet, and then remove the bean box from the bean box seat. At this time, the unlocking structure cancels the effect on the first opening and closing door limiting structure and / or the second opening and closing door limiting structure, and the first opening and closing door limiting structure and the second opening and closing door limiting structure are re-locked and matched to restrict the movement of the opening and closing door structure;

[0008] The above structure is reasonably arranged, and is convenient for the user to disassemble the bean box to perform other operations, such as cleaning and adding materials. It can also restrict the opening and closing door structure from opening the bean outlet after the bean box is removed from the bean box seat, and the structural design is well considered.

[0009] Further, one of the first opening and closing door limiting structure and the second opening and closing door limiting structure is configured as an opening and closing door limiting slot, and the other of the first opening and closing door limiting structure and the second opening and closing door limiting structure is configured as an opening and closing door limiting elastic buckle matching the opening and closing door limiting slot, and the opening and closing door limiting elastic buckle has a first working position capable of being inserted into the opening and closing door limiting slot, and a second working position capable of being separated from the opening and closing door limiting slot, and the opening and closing door limiting elastic buckle maintains the first working position in the absence of external force; when the bean box is installed on the bean box seat, the unlocking structure acts on the opening and closing door limiting elastic buckle to deform it and move it to the second working position.

[0010] By adopting the above structure, locking and unlocking of the first opening and closing door limiting structure and the second opening and closing door limiting structure are realized; specifically, after the opening and closing door structure closes the bean outlet and the bean box is taken out from the bean box seat, the opening and closing door limiting elastic buckle is not affected by other external forces to be located in the first working position, that is, the opening and closing door limiting elastic buckle is snapped into the opening and closing door limiting slot to realize the restriction on the movement of the opening and closing door structure; when the bean box is installed on the bean box seat, the unlocking structure acts on the opening and closing door limiting elastic buckle to make it move to the second working position, that is, the opening and closing door limiting elastic buckle is disengaged from the opening and closing door limiting slot to cancel the restriction on the movement of the opening and closing door structure; the above structure is simple and reasonably designed, the reliability of locking cooperation is high, and the possibility of accidental unlocking is reduced.

[0011] Further, the bean box seat is provided with a first bean box limiting structure, and the opening and closing door structure is provided with a second bean box limiting structure matching the first bean box limiting structure;

[0012] When the bean box is installed on the bean box seat and the opening and closing door structure opens the bean outlet, the first bean box limiting structure and the second bean box limiting structure are locked and matched to limit the separation of the bean box and the bean box seat;

[0013] When the bean box is installed on the bean box seat and the opening and closing door structure closes the bean outlet, the first bean box limiting structure and the second bean box limiting structure are unlocked and matched to allow the bean box to be separated from the bean box seat.

[0014] By adopting the above structure, the design of the bean box mechanism is more reasonable; when the bean box is installed on the bean box seat and the opening and closing door structure opens the bean outlet, the first bean box limiting structure and the second bean box limiting structure are locked and matched, and the user cannot remove the bean box from the bean box seat at this time; if the user wants to remove the bean box from the bean box seat, it is necessary to first operate the opening and closing door structure to close the bean outlet, at which time the first bean box limiting structure and the second bean box limiting structure are unlocked, and the user can remove the bean box from the bean box seat; the above structure can prevent the user from removing the bean box from the bean box seat when the opening and closing door structure opens the bean outlet, thereby causing the coffee beans in the bean box to fall out.

[0015] Further, one of the first bean box limiting structure and the second bean box limiting structure is configured as a bean box limiting slot, and the other of the first bean box limiting structure and the second bean box limiting structure is configured as a bean box limiting slider matching the bean box limiting slot; the bean box limiting slot extends along the movable direction of the opening and closing door structure; the bean box limiting slider is slidably arranged in the bean box limiting slot, and the upper side wall of the bean box limiting slot located above the bean box limiting slider is formed as an upper retaining wall of the bean box limiting slot, and the lower side wall located above and below the bean box limiting slider is formed as a lower retaining wall of the bean box limiting slot;

[0016] When the first bean box limiting structure is configured as the bean box limiting slot, an upper retaining wall of the bean box limiting slot is provided with an entry and exit passage for the bean box limiting slider to enter and exit the bean box limiting slot at a position corresponding to the position of the bean box limiting slot when the opening and closing door structure closes the bean outlet;

[0017] When the second bean box limiting structure is configured as the bean box limiting slot, a lower retaining wall of the bean box limiting slot is provided with an entry and exit passage for the bean box limiting slider to enter and exit the bean box limiting slot at a position corresponding to the position of the bean box limiting slot when the opening and closing door structure closes the bean outlet.

[0018] With the above structure, when the user wants to install the bean box on the bean box seat, he only needs to align the bean box limiting slider with the inlet and outlet channel. When the bean box is installed on the bean box seat, the bean box limiting slider enters the bean box limiting card slot through the inlet and outlet channel; the user operates the opening and closing door structure to open the bean outlet, and the bean box limiting slider will move synchronously with the opening and closing door structure, that is, the bean box limiting slider will slide along the bean box limiting card slot, and the cooperation between the bean box limiting slider and the bean box limiting card slot makes the movement of the opening and closing door structure smoother; at this time, if the user wants to move the bean box from the When the bean box is taken out from the bean box seat, the bean box limiting slider is limited between the upper retaining wall of the bean box limiting slot and the lower retaining wall of the bean box limiting slot, thereby limiting the separation of the bean box and the bean box seat; when the user wants to remove the bean box from the bean box seat, the opening and closing door structure should be operated first to close the bean outlet, at which time the bean box limiting slider moves with the opening and closing door structure, and at this time the bean box limiting slider is aligned with the in-and-out channel, and the bean box limiting slider can be disengaged from the bean box limiting slot from the in-and-out channel, that is, the bean box can be removed from the bean box seat; the above structure is simple in structure, reasonable in design, and reliable in operation.

[0019] Further, the bean box mechanism includes a trigger switch, and the opening and closing door structure is provided with a trigger part for triggering the trigger switch;

[0020] When the bean box is installed on the bean box seat and the opening and closing door structure opens the bean outlet, the trigger unit triggers the trigger switch;

[0021] When the bean box is installed on the bean box seat and the opening and closing door structure closes the bean outlet, the trigger part does not trigger the trigger switch.

[0022] With the above structure, when the bean box is installed on the bean box seat and the opening and closing door structure opens the bean outlet, the trigger unit triggers the trigger switch. At this time, the trigger switch can send a start permission signal to the control chip of the bean grinding device or connect the electrical components in the bean grinding device with the power supply, so that the grinding mechanism in the bean grinding device can be started to work; and when the bean box is installed on the bean box seat and the opening and closing door structure closes the bean outlet, the trigger unit does not trigger the trigger switch. At this time, the trigger switch does not send a start permission signal to the control chip of the bean grinding device or disconnect the electrical components in the bean grinding device with the power supply, so that the grinding mechanism in the bean grinding device cannot be started to work, effectively avoiding idling of the grinding mechanism and avoiding the operation of the grinding mechanism when the bean box seat is not installed on the bean box, which is safer.

[0023] Further, the bean box mechanism includes a trigger switch, and the trigger switch is installed on the bean box seat;

[0024] The first bean box limiting structure is configured as a bean box limiting slot, and the other of the second bean box limiting structures is configured as a bean box limiting sliding block matching the bean box limiting slot;

[0025] When the opening and closing door structure opens the bean outlet, the bean box limit slider is provided with a trigger opening at a position corresponding to the position of the bean box limit slot; the trigger switch comprises a switch body and a resettable trigger rod, one end of the trigger rod is provided on the switch body, the other end is formed as a trigger rod free end and extends through the trigger opening to the bean box limit slot where the trigger opening is provided;

[0026] When the bean box is mounted on the bean box seat and the opening and closing door structure opens the bean outlet, the bean box limiting slider acts on the free end of the trigger rod to trigger the trigger switch.

[0027] With the above structure, when the bean box is installed on the bean box seat, the bean box limit slider is located in the bean box limit slot. When the user operates the opening and closing door structure to open the bean outlet, the bean box limit slider slides to the trigger opening. Since the trigger rod of the trigger switch extends through the trigger opening to the bean box limit slot where the trigger opening is provided, the bean box limit slider acts on the free end of the trigger rod to trigger the trigger switch.

[0028] When the user operates the opening and closing door structure to close the bean outlet, the bean box limit slider slides to the entry and exit channel, that is, the bean box limit slider leaves the trigger opening, so the bean box limit slider does not act on the free end of the trigger rod, and the trigger switch is not triggered; the above structural design is more reasonable and can simplify the structure, so that the bean box limit slider is formed as the trigger part.

[0029] Specifically, the trigger opening is arranged on the side wall of the bean box limiting slot, and correspondingly, the trigger switch is arranged on the outer side wall of the bean box seat; the trigger switch includes a reset member, and the reset member acts on the trigger rod to enable it to be reset; the above structure makes the position setting of the trigger switch more reasonable, minimizes the impact on the falling beans and other functions, and can make more reasonable use of space.

[0030] Furthermore, along the direction in which the bean box is installed on the bean box seat, at least one side of the outer side wall of the opening and closing door limiting elastic buckle toward the opening and closing door limiting slot that contacts the unlocking structure before is configured as a first guide surface for guiding the opening and closing door limiting elastic buckle to move toward the second working position side after the unlocking structure acts on it, and the first guide surface is inclined toward the side away from the opening and closing door limiting slot along the direction in which the bean box is installed on the bean box seat.

[0031] With the above structure, the setting of the first guide surface enables the unlocking structure to contact and act on the first guide surface when the bean box is installed on the bean box seat, so that the opening and closing door limiting elastic buckle can move to the second working position more effectively and stably under the action of the unlocking structure; the above structure enables the unlocking structure and the opening and closing door limiting elastic buckle to cooperate more effectively and stably.

[0032] Further, the first opening and closing door limiting structure is configured as an opening and closing door limiting slot, and the second opening and closing door limiting structure is configured as an opening and closing door limiting elastic buckle matching the opening and closing door limiting slot;

[0033] The opening and closing door structure is arranged on the outer side of the bean box on the side where the bean outlet is arranged, and the side of the opening and closing door limit elastic buckle facing the bean box protrudes from the side of the opening and closing door structure facing the bean box; a matching slide groove matching the part of the opening and closing door limit elastic buckle protruding from the side of the opening and closing door structure facing the bean box is arranged on the side of the bean box facing the opening and closing door structure, and the matching slide groove matches the moving track of the part of the opening and closing door limit elastic buckle protruding from the opening and closing door structure when the opening and closing door structure moves;

[0034] When the opening and closing door structure opens the bean outlet, the part of the opening and closing door limiting elastic buckle protruding from the side of the opening and closing door structure facing the bean box abuts against the first matching chute side wall of the matching chute; when the opening and closing door structure closes the bean outlet, the part of the opening and closing door limiting elastic buckle protruding from the side of the opening and closing door structure facing the bean box abuts against the second matching chute side wall of the matching chute;

[0035] A matching block is provided on the bottom surface of the matching slide groove between the first matching slide groove side wall and the second matching slide groove side wall and close to one side of the second matching slide groove side wall, and the spacing distance between the matching block and the second matching slide groove side wall toward the second matching slide groove side wall matches the width of the opening and closing door limiting elastic buckle protruding from the side of the opening and closing door structure toward the bean box; the opening and closing door limiting slot is formed between the matching block and the second matching slide groove side wall toward the second matching slide groove side wall.

[0036] With the above structure, when the opening and closing door structure is operated to move, the part of the opening and closing door limiting elastic buckle protruding from the opening and closing door structure toward the bean box will slide along the matching slide groove, and the first matching slide groove side wall and the second matching slide groove side wall restrict the sliding of the opening and closing door limiting elastic buckle, that is, the movement of the opening and closing door structure is restricted to avoid excessive movement, and it is easier to confirm the position of opening the bean outlet and the position of closing the bean outlet;

[0037] And due to the setting of the matching block, the part of the opening and closing door limiting elastic buckle protruding from the opening and closing door structure toward the bean box can be clamped between the matching block and the side wall of the second matching slide groove to limit the movement of the opening and closing door limiting elastic buckle, that is, to limit the movement of the opening and closing door structure, and realize the function of the opening and closing door limiting slot; the above structure is reasonably designed and simple in structure, and is easy to implement.

[0038] Furthermore, the opening and closing door limiting elastic buckle is configured as a second guide surface for guiding it into the opening and closing door limiting slot at least on a side of the portion protruding from the opening and closing door structure toward the bean box and facing the second matching slide slot side wall.

[0039] With the above structure, the second guide surface is set so that when the opening and closing door limit elastic buckle slides toward the side wall of the second matching slide groove, it can easily pass over the matching block to enter between the matching block and the side wall of the second matching slide groove; specifically, the second guide surface is an arc surface.

[0040] Furthermore, when the bean box is installed on the bean box seat, the unlocking structure is located below the matching slide groove, and along the direction from the first working position to the second working position of the opening and closing door limit elastic buckle, the distance of the unlocking structure toward the outer wall of the opening and closing door structure is less than or equal to the distance of the opening and closing door limit slot toward the outer wall of the opening and closing door structure.

[0041] By adopting the above structure, the unlocking structure is more reasonably set; when the bean box is installed on the bean box seat, the unlocking structure can act on the opening and closing door limit elastic buckle to make it move away from the matching slide groove, thereby realizing the opening and closing door limit elastic buckle to be disengaged from the opening and closing door limit slot.

[0042] Furthermore, one end of the opening and closing door limiting elastic buckle is arranged on the opening and closing door structure, and the other end is formed as a buckle free end to enable it to have deformation ability.

[0043] By adopting the above structure, the elastic deformation ability of the opening and closing door limit elastic buckle is realized, so that it has the ability to reset, that is, it can be maintained in the first working position without external force; the above structure is simple, reasonable and reliable; specifically, a buckle part is provided on the protrusion of the free end of the buckle.

[0044] Further, a first inlet and outlet opening is formed on one side of the inlet and outlet channel communicating with the bean box limiting slot, and a second inlet and outlet opening is formed on the other side opposite to the first inlet and outlet opening;

[0047] With the above structure, the first inlet and outlet guide surface is provided so that when the bean box is installed on the bean box seat, the bean box limiting slider can be more conveniently aligned with the inlet and outlet channel and enter the inlet and outlet channel;

[0048] The second inlet and outlet guide surface is provided so that when the bean box limiting slider passes through the inlet and outlet passage and enters the bean box limiting slot, if the bean box limiting slider is not fully inserted, the user operates the opening and closing door structure, and the bean box limiting slider slides accordingly. At this time, the bean box limiting slider contacts the second inlet and outlet guide surface, and under the guidance of the second inlet and outlet guide surface, the bean box limiting slider fully enters the bean box limiting slot. The above-mentioned structural design is reasonable, making the installation of the bean box more convenient and quick.

[0049] Furthermore, a bean-dropping guide surface is provided on the side wall of the bean outlet radially protruding inward, and at least one side of the bean-dropping guide surface gradually extends obliquely in the bean-dropping direction; a bean outlet hole for discharging beans is formed in the bean outlet at a portion not covered by the bean-dropping guide surface; specifically, a plurality of the bean-dropping guide surfaces are circumferentially spaced apart on the side wall of the bean outlet, and one end of the plurality of bean-dropping guide surfaces away from the side wall of the bean outlet is connected at the center of the bean outlet, and a bean outlet hole is formed between two adjacent bean-dropping guide surfaces; more specifically, two bean-dropping guide surfaces are provided; and the bean-dropping guide surfaces are equally spaced.

[0082] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0083] See also Figures 1 to 6 The utility model provides a bean box mechanism, comprising a bean box seat 1, and a bean box 2 detachably arranged on the bean box seat 1; the bean box 2 is provided with a bean outlet 201 for discharging beans, and an opening and closing door structure 3 matching the bean outlet 201 is movably arranged in the bean box 2 to control the opening and closing of the bean outlet 201; a first opening and closing door limiting structure 202 is provided on the bean box 2, and a second opening and closing door limiting structure 301 is provided on the opening and closing door structure 3 to lock and cooperate with the first opening and closing door limiting structure 202 when the opening and closing door structure 3 closes the bean outlet 201 to limit the movement of the opening and closing door structure 3; the bean box seat 1 is provided with an unlocking structure 101 for unlocking the first opening and closing door limiting structure 202 and the second opening and closing door limiting structure 301 when the bean box 2 is installed on the bean box seat 1.

[0084] With the above structure, when in use, the user can operate the opening and closing door structure 3 to open and close the bean outlet 201, so that the user can take out the bean box 2 from the bean box seat 1 when there are still coffee beans in the bean box 2; and when the user takes out the bean box 2 from the bean box seat 1 with the opening and closing door structure 3 closing the bean outlet 201, the first opening and closing door limiting structure 202 and the second opening and closing door limiting structure 301 are locked and matched to limit the movement of the opening and closing door structure 3 to prevent the bean outlet 201 from being accidentally opened;

[0085] When the user installs the bean box 2 on the bean box seat 1, the unlocking structure 101 on the bean box seat 1 will act on the first opening and closing door limiting structure 202 and / or the second opening and closing door limiting structure 301, so that the first opening and closing door limiting structure 202 and the second opening and closing door limiting structure 301 are unlocked, and the restriction on the movement of the opening and closing door structure 3 is cancelled. At this time, the user can operate the opening and closing door structure 3 to make the opening and closing door structure 3 move to open the bean outlet 201; when the user wants to remove the bean box 2 from the bean box seat 1, it is only necessary to operate the opening and closing door structure 3 to close the bean outlet 201, and then remove the bean box 2 from the bean box seat 1. At this time, the unlocking structure 101 cancels the effect on the first opening and closing door limiting structure 202 and / or the second opening and closing door limiting structure 301, and the first opening and closing door limiting structure 202 and the second opening and closing door limiting structure 301 are re-locked and matched to restrict the movement of the opening and closing door structure 3;

[0086] The above structure is reasonably arranged, and is convenient for the user to disassemble the bean box 2 to perform other operations, such as cleaning and adding materials thereto; and can restrict the opening and closing door structure 3 from opening the bean outlet 201 after the bean box 2 is removed from the bean box seat 1, and the structural design is well considered.

[0087] Further, one of the first opening and closing door limiting structure 202 and the second opening and closing door limiting structure 301 is configured as an opening and closing door limiting slot 4, and the other of the first opening and closing door limiting structure 202 and the second opening and closing door limiting structure 301 is configured as an opening and closing door limiting elastic buckle 5 matching the opening and closing door limiting slot 4, and the opening and closing door limiting elastic buckle 5 has a first working position capable of being inserted into the opening and closing door limiting slot 4, and a second working position capable of being separated from the opening and closing door limiting slot 4, and the opening and closing door limiting elastic buckle 5 maintains the first working position in the absence of external force; when the bean box 2 is installed on the bean box seat 1, the unlocking structure 101 acts on the opening and closing door limiting elastic buckle 5 to deform it and move it to the second working position.

[0088] By adopting the above structure, the locking and unlocking of the first opening and closing door limiting structure 202 and the second opening and closing door limiting structure 301 are realized; specifically, after the opening and closing door structure 3 closes the bean outlet 201 and the bean box 2 is taken out from the bean box seat 1, the opening and closing door limiting elastic buckle 5 is not affected by other external forces to be located in the first working position, that is, the opening and closing door limiting elastic buckle 5 is snapped into the opening and closing door limiting slot 4 to realize the restriction of the movement of the opening and closing door structure 3; when the bean box 2 is installed on the bean box seat 1, the unlocking structure 101 acts on the opening and closing door limiting elastic buckle 5 to make it move to the second working position, that is, the opening and closing door limiting elastic buckle 5 is disengaged from the opening and closing door limiting slot 4 to cancel the restriction on the movement of the opening and closing door structure 3; the above structure is simple and reasonably designed, the reliability of locking cooperation is high, and the possibility of accidental unlocking is reduced.

[0089] Furthermore, the bean box seat 1 is provided with a first bean box limiting structure 102, and the opening and closing door structure 3 is provided with a second bean box limiting structure 302 matching the first bean box limiting structure 102;

[0090] When the bean box 2 is installed on the bean box seat 1 and the opening and closing door structure 3 opens the bean outlet 201, the first bean box limiting structure 102 and the second bean box limiting structure 302 are locked and matched to limit the separation of the bean box 2 and the bean box seat 1;

[0091] When the bean box 2 is installed on the bean box seat 1 and the opening and closing door structure 3 closes the bean outlet 201, the first bean box limiting structure 102 and the second bean box limiting structure 302 are unlocked and matched to allow the bean box 2 to be separated from the bean box seat 1.

[0092] By adopting the above structure, the design of the bean box mechanism is more reasonable; when the bean box 2 is installed on the bean box seat 1 and the opening and closing door structure 3 opens the bean outlet 201, the first bean box limiting structure 102 and the second bean box limiting structure 302 are locked and matched, and the user cannot remove the bean box 2 from the bean box seat 1 at this time; if the user wants to remove the bean box 2 from the bean box seat 1, it is necessary to first operate the opening and closing door structure 3 to close the bean outlet 201, at this time, the first bean box limiting structure 102 and the second bean box limiting structure 302 are unlocked, and the user can remove the bean box 2 from the bean box seat 1; the above structure can prevent the user from removing the bean box 2 from the bean box seat 1 when the opening and closing door structure 3 opens the bean outlet 201, thereby causing the coffee beans in the bean box 2 to fall out.

[0093] Further, one of the first bean box limiting structure 102 and the second bean box limiting structure 302 is configured as a bean box limiting slot 6, and the other of the first bean box limiting structure 102 and the second bean box limiting structure 302 is configured as a bean box limiting slider 7 matching the bean box limiting slot 6; the bean box limiting slot 6 extends along the movable direction of the opening and closing door structure 3; the bean box limiting slider 7 is slidably arranged in the bean box limiting slot 6, and the upper side wall of the bean box limiting slot 6 located above the bean box limiting slider 7 is formed as an upper retaining wall 601 of the bean box limiting slot, and the lower side wall located above and below the bean box limiting slider 7 is formed as a lower retaining wall 602 of the bean box limiting slot;

[0094] When the first bean box limiting structure 102 is configured as the bean box limiting slot 6, the upper retaining wall 601 of the bean box limiting slot is provided with an inlet and outlet passage 603 for the bean box limiting slider 7 to enter and exit the bean box limiting slot 6 at a position corresponding to the position of the bean box limiting slider 7 when the opening and closing door structure 3 closes the bean outlet 201;

[0095] When the second bean box limiting structure 302 is configured as the bean box limiting slot 6, the lower retaining wall 602 of the bean box limiting slot is provided with an inlet and outlet passage 603 for the bean box limiting slider 7 to enter and exit the bean box limiting slot 6 at a position corresponding to the position of the bean box limiting slider 7 when the opening and closing door structure 3 closes the bean outlet 201.

[0096] With the above structure, when the user wants to install the bean box 2 on the bean box seat 1, he only needs to align the bean box limiting slider 7 with the inlet and outlet channel 603. When the bean box 2 is installed on the bean box seat 1, the bean box limiting slider 7 enters the bean box limiting card slot 6 through the inlet and outlet channel 603; the user operates the opening and closing door structure 3 to open the bean outlet 201, and the bean box limiting slider 7 will move synchronously with the opening and closing door structure 3, that is, the bean box limiting slider 7 will slide along the bean box limiting card slot 6, and the cooperation between the bean box limiting slider 7 and the bean box limiting card slot 6 makes the movement of the opening and closing door structure 3 smoother; at this time, if the user wants to take the bean box 2 out of the bean box When the bean box 2 is removed from the bean box seat 1, the bean box limiting slider 7 is limited between the upper retaining wall 601 of the bean box limiting slot and the lower retaining wall 602 of the bean box limiting slot, thereby limiting the separation of the bean box 2 from the bean box seat 1; when the user wants to remove the bean box 2 from the bean box seat 1, the opening and closing door structure 3 should be operated to close the bean outlet 201, and the bean box limiting slider 7 moves with the opening and closing door structure 3. At this time, the bean box limiting slider 7 is aligned with the in-and-out channel 603, and the bean box limiting slider 7 can be separated from the bean box limiting slot 6 from the in-and-out channel 603, that is, the bean box 2 can be removed from the bean box seat 1; the above structure is simple in structure, reasonable in design, and reliable in operation.

[0097] Furthermore, the bean box mechanism includes a trigger switch 8, and the opening and closing door structure 3 is provided with a trigger part 303 for triggering the trigger switch 8;

[0098] When the bean box 2 is installed on the bean box seat 1 and the opening and closing door structure 3 opens the bean outlet 201, the trigger unit 303 triggers the trigger switch 8;

[0099] When the bean box 2 is installed on the bean box seat 1 and the opening and closing door structure 3 closes the bean outlet 201 , the trigger unit 303 does not trigger the trigger switch 8 .

[0100] With the above structure, when the bean box 2 is mounted on the bean box seat 1 and the opening and closing door structure 3 opens the bean outlet 201, the trigger unit 303 triggers the trigger switch 8. At this time, the trigger switch 8 can send a start permission signal to the control chip of the bean grinding device or connect the electrical components in the bean grinding device with the power supply, so that the grinding mechanism in the bean grinding device can be started to work; and when the bean box 2 is mounted on the bean box seat 1 and the opening and closing door structure 3 closes the bean outlet 201, the trigger unit 303 does not trigger the trigger switch 8. At this time, the trigger switch 8 does not send a start permission signal to the control chip of the bean grinding device or disconnect the electrical components in the bean grinding device with the power supply, so that the grinding mechanism in the bean grinding device cannot be started to work, effectively avoiding idling of the grinding mechanism and avoiding the operation of the grinding mechanism when the bean box 2 is not mounted on the bean box 2, which is safer.

[0101] Furthermore, the bean box mechanism includes a trigger switch 8, and the trigger switch 8 is installed on the bean box seat 1;

[0102] The first bean box limiting structure 102 is configured as a bean box limiting slot 6, and the other one of the second bean box limiting structures 302 is configured as a bean box limiting slider 7 matching the bean box limiting slot 6;

[0103] When the opening and closing door structure 3 opens the bean outlet 201, the bean box limiting slider 7 is provided with a trigger opening 604 at a position corresponding to the position of the bean box limiting slot 6; the trigger switch 8 comprises a switch body 801 and a resettable trigger rod 802, one end of the trigger rod 802 is provided on the switch body 801, the other end is formed as a trigger rod free end 8021 and extends through the trigger opening 604 to the bean box limiting slot 6 where the trigger opening 604 is provided;

[0104] When the bean box 2 is installed on the bean box seat 1 and the opening and closing door structure 3 opens the bean outlet 201 , the bean box limiting slider 7 acts on the free end of the trigger rod 802 to trigger the trigger switch 8 .

[0105] With the above structure, when the bean box 2 is installed on the bean box seat 1, the bean box limiting slider 7 is located in the bean box limiting slot 6. When the user operates the opening and closing door structure 3 to open the bean outlet 201, the bean box limiting slider 7 slides to the trigger opening 604. Since the trigger rod 802 of the trigger switch 8 extends through the trigger opening 604 to the bean box limiting slot 6 where the trigger opening 604 is provided, the bean box limiting slider 7 acts on the free end of the trigger rod 802 to trigger the trigger switch 8.

[0106] When the user operates the opening and closing door structure 3 to close the bean outlet 201, the bean box limiting slider 7 slides to the inlet and outlet channel 603, that is, the bean box limiting slider 7 leaves the trigger opening 604, so the bean box limiting slider 7 does not act on the free end of the trigger rod 802, and the trigger switch 8 is not triggered; the above structural design is more reasonable and can simplify the structure, so that the bean box limiting slider 7 is formed as the trigger part 303.

[0107] Specifically, the trigger opening 604 is arranged on the side wall of the bean box limiting slot 6, and correspondingly, the trigger switch 8 is arranged on the outer side wall of the bean box seat 1; the trigger switch 8 includes a reset member 803, and the reset member 803 acts on the trigger rod 802 to enable it to be reset; the above structure makes the position setting of the trigger switch 8 more reasonable, minimizes the impact on the falling beans and other functions, and can make more reasonable use of space.

[0108] Further, along the direction in which the bean box 2 is installed on the bean box seat 1, at least one side of the outer side wall of the opening and closing door limiting elastic buckle 5 facing the opening and closing door limiting slot 4 that contacts the unlocking structure 101 is configured as a first guide surface 501 that guides the opening and closing door limiting elastic buckle 5 to move toward the second working position side after the unlocking structure 101 acts thereon, and the first guide surface 501 is inclined toward the side away from the opening and closing door limiting slot 4 along the direction in which the bean box 2 is installed on the bean box seat 1.

[0109] With the above structure, the setting of the first guide surface 501 enables the unlocking structure 101 to contact and act on the first guide surface 501 when the bean box 2 is installed on the bean box seat 1, so that the opening and closing door limiting elastic buckle 5 can move to the second working position more effectively and stably under the action of the unlocking structure 101; the above structure enables the unlocking structure 101 and the opening and closing door limiting elastic buckle 5 to cooperate more effectively and stably.

[0110] Further, the first opening and closing door limiting structure 202 is configured as an opening and closing door limiting card slot 4, and the second opening and closing door limiting structure 301 is configured as an opening and closing door limiting elastic buckle 5 matching the opening and closing door limiting card slot 4;

[0111] The opening and closing door structure 3 is arranged on the outer side of the bean box 2 on the side where the bean outlet 201 is arranged, and the side of the opening and closing door limit elastic buckle 5 facing the bean box 2 protrudes from the side of the opening and closing door structure 3 facing the bean box 2; the side of the bean box 2 facing the opening and closing door structure 3 is provided with a matching slide groove 203 matching the part of the opening and closing door limit elastic buckle 5 protruding from the side of the opening and closing door structure 3 facing the bean box 2, and the matching slide groove 203 matches the moving track of the part of the opening and closing door limit elastic buckle 5 protruding from the opening and closing door structure 3 when the opening and closing door structure 3 moves;

[0112] When the opening and closing door structure 3 opens the bean outlet 201, the portion of the opening and closing door limiting elastic buckle 5 protruding from the opening and closing door structure 3 toward the bean box 2 abuts against the first matching slide groove side wall 2031 of the matching slide groove 203; when the opening and closing door structure 3 closes the bean outlet 201, the portion of the opening and closing door limiting elastic buckle 5 protruding from the opening and closing door structure 3 toward the bean box 2 abuts against the second matching slide groove side wall 2032 of the matching slide groove 203;

[0113] A matching block 2033 is protruded from the bottom surface of the matching slide groove 203 between the first matching slide groove side wall 2031 and the second matching slide groove side wall 2032 and close to one side of the second matching slide groove side wall 2032, and the spacing distance between the matching block 2033 and the second matching slide groove side wall 2032 toward the second matching slide groove side wall 2032 matches the width of the opening and closing door limiting elastic buckle 5 protruding from the side of the opening and closing door structure 3 toward the bean box 2; the opening and closing door limiting card groove 4 is formed between the matching block 2033 and the second matching slide groove side wall 2032 toward the second matching slide groove side wall 2032.

[0114] With the above structure, when the opening and closing door structure 3 is operated to move, the part of the opening and closing door limiting elastic buckle 5 protruding from the opening and closing door structure 3 toward the bean box 2 will slide along the matching slide groove 203, and the first matching slide groove side wall 2031 and the second matching slide groove side wall 2032 limit the sliding of the opening and closing door limiting elastic buckle 5, that is, the movement of the opening and closing door structure 3 is limited to avoid excessive movement, and it is easier to confirm the position of opening the bean outlet 201 and the position of closing the bean outlet 201;

[0115] And due to the setting of the matching block 2033, the part of the opening and closing door limiting elastic buckle 5 protruding from the opening and closing door structure 3 toward the bean box 2 can be clamped between the matching block 2033 and the second matching slide groove side wall 2032 to limit the movement of the opening and closing door limiting elastic buckle 5, that is, to limit the movement of the opening and closing door structure 3, and realize the function of the opening and closing door limiting slot 4; the above-mentioned structure is reasonably designed and simple in structure, and is easy to implement.

[0116] Furthermore, the opening and closing door limiting elastic buckle 5 is configured to be used for guiding it into the second guide surface 502 of the opening and closing door limiting slot 4 at least on the side of the part protruding from the opening and closing door structure 3 toward the bean box 2 and facing the second matching slide slot side wall 2032.

[0117] By adopting the above structure, the setting of the second guide surface 502 enables the opening and closing door limiting elastic buckle 5 to easily pass over the matching block 2033 and enter between the matching block 2033 and the second matching slot side wall 2032 when it slides toward the second matching slot side wall 2032; specifically, the second guide surface 502 is an arc surface.

[0118] Furthermore, when the bean box 2 is installed on the bean box seat 1, the unlocking structure 101 is located below the matching slide groove 203, and along the direction from the first working position to the second working position of the opening and closing door limit elastic buckle 5, the distance of the unlocking structure 101 toward the outer wall of the opening and closing door structure 3 is less than or equal to the distance of the opening and closing door limit slot 4 toward the outer wall of the opening and closing door structure 3.

[0119] By adopting the above structure, the unlocking structure 101 is more reasonably set; when the bean box 2 is installed on the bean box seat 1, the unlocking structure 101 can act on the opening and closing door limit elastic buckle 5 to move it away from the matching slide groove 203, thereby realizing the opening and closing door limit elastic buckle 5 to be disengaged from the opening and closing door limit slot 4.

[0120] Furthermore, one end of the opening and closing door limiting elastic buckle 5 is arranged on the opening and closing door structure 3, and the other end is formed as a buckle free end 503 to enable it to have deformation ability.

[0121] By adopting the above structure, the elastic deformation ability of the opening and closing door limit elastic buckle 5 is realized, so that it has the ability to reset, that is, it can be maintained in the first working position without external force; the above structure is simple, reasonable and reliable; specifically, a buckle portion 504 is protruded on the free end 503 of the buckle.

[0122] Further, a first inlet and outlet opening 6031 is formed on one side of the inlet and outlet channel 603 communicating with the bean box limiting slot 6, and a second inlet and outlet opening 6032 is formed on the other side opposite to the first inlet and outlet opening 6031;
