Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and in particular to a rotary powder removal structure for a coffee machine powder container. Background Technology

[0002] As living standards improve, coffee has gradually become a common beverage in people's lives. Due to the fast pace of life, coffee machines that can quickly brew coffee are increasingly popular. Some users prefer to place coffee grounds in the coffee hopper when brewing. After brewing, the grounds, compressed and extracted, tend to stick to the hopper. If the user wants to brew again, they need to empty the coffee grounds from the hopper. However, in some cases, the grounds cannot be easily removed. In such situations, the hopper needs to be rinsed or forcefully tapped to dislodge the grounds. This can make the extraction process cumbersome or noisy, and in some cases, rinsing is not possible, adding extra steps to the process and failing to achieve the goal of quickly removing coffee grounds from the hopper. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rotary powder removal structure for the powder container of a coffee machine, in light of the current state of the technology.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A rotary powder removal structure for a coffee machine powder container includes a powder container body; the powder container body includes an upper shell and a lower shell; the upper shell and the lower shell are rotatably engaged; an extraction chamber is provided inside the upper shell; a base assembly is provided inside the upper shell, one end of the base assembly passing through the lower shell, and at least one inclined guide portion is provided inside the lower shell; an abutment member is provided at one end of the base assembly in the lower shell, which abuts against the guide portion; rotating the lower shell changes the position of the abutment member on the guide portion, causing the base assembly to move within the extraction chamber in a limited manner.

[0005] The aforementioned components achieve the following effects: by rotating and snapping together the upper and lower shells, the lower shell can rotate relative to the upper shell; by providing an extraction chamber within the upper shell, coffee grounds can be extracted within the extraction chamber; a base assembly is provided for holding the coffee grounds; and by providing a guide and an abutment, with the guide being inclined and the abutment connected to the guide, when the user rotates the lower shell, the abutment, through the inclined structure of the guide, moves along the guide, causing the base assembly to rise within the extraction chamber. Subsequently, the coffee grounds within the base assembly can rise along with it, allowing the user to more easily pour the coffee grounds out of the extraction chamber without rinsing or forcefully tapping.

[0006] Preferably, the guide portion is disposed at the bottom of the lower housing and extends upward, and the guide portion is arranged in a ring inside the lower housing; the two ends of the guide portion are a first guide end and a second guide end; the height of the first guide end is at least not higher than the height of the second guide end.

[0007] The effect achieved by the above components is as follows: by setting the guide part at the bottom of the lower housing, the guide part can rotate synchronously with the lower housing. By setting the first guide end and the second guide end, the abutment can move between the first guide end and the second guide end. The height of the first guide end is at least no higher than the second guide end. When the abutment can move from the position of the first guide end to the position of the second guide end, the base assembly also rises together because of the increase in the height of the guide part.

[0008] Preferably, the distance between the end of the abutting member that abuts against the guide portion and the bottom of the lower housing is at least not less than the height of the first guide end.

[0009] The effect achieved by the above components is that the distance between the abutment and the bottom of the lower housing is set to be greater than the height of the first guide end, so that when at least two guide parts are provided in the lower housing and there is a gap between the guide parts, the abutment will not get stuck outside the guide parts and will not be able to rotate.

[0010] Preferably, the bottom of the upper housing is provided with a through hole for the abutment to pass through.

[0013] The aforementioned components achieve the following effects: by setting up a filter screen, they filter coffee grounds; by setting up fixing screws, the filter screen can be fixedly connected to the fixing base; by setting up a fixing tube, and the fixing base extending downwards from the housing, and setting up a fixing head, they limit the placement of the return spring. The return spring is sleeved on the fixing tube, so when the base assembly rises, the return spring will be compressed. When the contact part leaves the second guide end, the return spring will elastically reset, allowing the base assembly to be reset and moved downwards.

[0014] Preferably, a connecting seat is provided inside the lower housing; the connecting seat is fixedly connected to the lower end face of the upper housing; and a fixing position is provided on the fixing seat.

[0015] The effect achieved by the above components is that, by setting the connecting seat and placing the connecting seat on the lower end face of the upper housing, the connecting seat will not move with the base assembly.

[0016] Preferably, the bottom of the upper housing is provided with a liquid passage hole; the lower housing is provided with a sealing element and an elastic element; the elastic element is disposed between the sealing element and the fixed position; the sealing element can be connected to or separated from the liquid passage hole.

[0017] The effects achieved by the above components are as follows: by setting a liquid passage hole, coffee liquid in the extraction chamber can flow out through the liquid passage hole; by setting a fixing position, elastic element is placed to limit its placement; and by setting a sealing element, the liquid passage hole is blocked. When the pressure in the extraction chamber is too high, the elastic element and the sealing element will be squeezed downwards, which will then separate the sealing element from the liquid passage hole, allowing coffee liquid to flow out through the liquid passage hole. When the pressure decreases, the elastic element will elastically reset and drive the sealing element to abut against the liquid passage hole.

[0018] Preferably, the bottom of the lower housing is provided with a liquid outlet.

[0019] The effect achieved by the above-mentioned components is that, by setting up a liquid outlet, coffee liquid can flow out from the liquid outlet for the user to drink.

[0028] like Figures 1 to 5 As shown, this utility model provides a rotating powder removal structure for a coffee machine powder container, including a powder container body 1; the powder container body 1 includes an upper shell 11 and a lower shell 12; the upper shell 11 and the lower shell 12 are rotatably engaged; an extraction chamber 13 is provided inside the upper shell 11; a base assembly 2 is provided inside the upper shell 11, one end of the base assembly 2 passes through the lower shell 12, and at least one inclined guide portion 3 is provided inside the lower shell 12; an abutment member 21 is provided at one end of the base assembly 2 on the lower shell 12, which abuts against the guide portion 3; rotating the lower shell 12 changes the position of the abutment member 21 on the guide portion 3, causing the base assembly 2 to move within the extraction chamber 13 in a limited manner. By rotating and engaging the upper shell 11 and the lower shell, the lower shell 12 can rotate relative to the upper shell 11. An extraction chamber 13 is provided inside the upper shell 11, allowing coffee powder to be extracted within the extraction chamber 13. A base assembly 2 is provided for holding the coffee powder. A guide part 3 and an abutment member 21 are provided, with the guide part 3 being inclined and the abutment member 21 abutting against the guide part 3. When the user rotates the lower shell 12, the abutment member 21, through the inclined structure of the guide part 3, moves along the guide part 3, causing the base assembly 2 to rise within the extraction chamber 13. Subsequently, the coffee grounds in the base assembly 2 can rise along with it, making it easier for the user to pour the coffee grounds out of the extraction chamber 13.

[0029] The rotational snap-fit ​​connection between the upper shell 11 and the lower shell in this utility model is a conventional and well-known connection method for those skilled in the art, and does not require further description or accompanying drawings.

[0030] The guide portion 3 is disposed at the bottom of the lower housing 12 and extends upward, and is arranged in a ring within the lower housing 12. The two ends of the guide portion 3 are a first guide end 31 and a second guide end 32. The height of the first guide end 31 is at least not higher than the height of the second guide end 32. By disposing of the guide portion 3 at the bottom of the lower housing 12, the guide portion 3 can rotate synchronously with the lower housing 12. By providing the first guide end 31 and the second guide end 32, the abutment member 21 can move between the first guide end 31 and the second guide end 32. The height of the first guide end 31 is at least not higher than the second guide end 32. When the abutment member 21 moves from the position of the first guide end 31 to the position of the second guide end 32, the base assembly 2 also rises due to the increase in the height of the guide portion 3.

[0031] The distance between the end of the abutting member 21 that abuts against the guide portion 3 and the bottom of the lower housing 12 is at least not less than the height of the first guide end 31. Setting the distance between the abutting member 21 and the bottom of the lower housing 12 to be greater than the height of the first guide end 31 ensures that when at least two guide portions 3 are provided inside the lower housing 12 and a gap is provided between the guide portions 3, the abutting member 21 will not get stuck outside the guide portion 3 and will be unable to rotate.

[0032] The bottom of the upper housing 11 is provided with a through hole 14 for the abutment member 21 to pass through. By providing the through hole 14, the abutment member 21 can pass through the through hole 14 and then make contact with the guide part 3.

[0033] The base assembly 2 also includes a filter screen 22 and a fixing seat 23 disposed below the filter screen 22; the filter screen 22 is connected to the fixing seat 23 above by at least one fixing screw 27; the fixing seat 23 extends into the lower housing 12 and is provided with a fixing tube 24; a fixing head 25 is provided at the end of the fixing tube 24; a return spring 26 is sleeved on the fixing tube 24; the two ends of the return spring 26 respectively abut against the upper wall of the lower housing 12 and the fixing head 25. The filter screen 22 is used to filter coffee grounds; the fixing screw 27 is used to fix the filter screen 22 to the fixing base 23; the fixing tube 24 is used, and the fixing base 23 extends downward to the housing 12, and a fixing head 25 is used to limit the placement of the return spring 26. The return spring 26 is sleeved on the fixing tube 24, so when the base assembly 2 rises, the return spring 26 will be squeezed. When the contact member 21 leaves the second guide end 32, the return spring 26 will elastically reset and move the base assembly 2 downward.

[0034] A connecting seat 4 is provided inside the lower housing 12; the connecting seat 4 is fixedly connected to the lower end face of the upper housing 11; a fixing position 43 is provided on the fixing seat 23. By providing the connecting seat 4, and the connecting seat 4 being located on the lower end face of the upper housing 11, the connecting seat 4 will not move with the base assembly 2.

[0035] The connection method between the connecting seat 4 and the upper housing 11 described in this utility model includes any one of the following fixed connection methods: snap-fit, screw connection, sliding connection, etc. This utility model does not limit the connection to a single method. The above connection methods are conventional and well-known connection structures for those skilled in the art, and do not require much further explanation.

[0036] The upper housing 11 has a liquid passage hole 15 at its bottom; the lower housing 12 has a sealing member 41 and an elastic member 42 inside; the elastic member 42 is disposed between the sealing member 41 and the fixing position 43; the sealing member 41 can be connected to or separated from the liquid passage hole 15. The liquid passage hole 15 allows coffee liquid in the extraction chamber 13 to flow out through it. The fixing position 43 limits the placement of the elastic member 42. The sealing member 41 blocks the liquid passage hole 15. When the pressure in the extraction chamber 13 is too high, it will squeeze the elastic member 42 and the sealing member 41 downwards, causing the sealing member 41 to separate from the liquid passage hole 15, allowing coffee liquid to flow out through the liquid passage hole 15. When the pressure decreases, the elastic member 42 elastically resets, causing the sealing member 41 to contact the liquid passage hole 15.

[0037] The bottom of the lower housing 12 is provided with a liquid outlet 16. By providing the liquid outlet 16, coffee liquid can flow out from the liquid outlet 16 for the user to drink.

[0038] In this embodiment, when the user needs to use the powder container body 1, the coffee powder can be placed in the extraction chamber 13 for extraction. During the extraction process, the pressure in the extraction chamber 13 will increase, which will push the sealing member 41. Then the coffee liquid will enter the lower housing 12 through the liquid passage 15 and flow out from the liquid outlet 16. After the extraction is completed, the elastic member 42 will drive the sealing member 41 to reset and seal the liquid passage 15.

[0039] When the user needs to pour out the coffee grounds in the extraction chamber 13, the lower housing 12 needs to be rotated. At this time, the contact member 21 will move from the first guide end 31 to the second guide end 32. The base assembly 2 will rise, and the return spring 26 outside the fixing tube 24 will also be squeezed. Then the coffee grounds will rise with the base assembly 2, and the user can pour out the coffee grounds. When the contact member leaves the second guide end 32, the return spring 26 will bring the base assembly 2 back to its original position.
