Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically to a coffee powder receiver. Background Technology

[0002] As living standards improve, coffee has gradually become a common beverage in people's lives, leading to an increasing demand for coffee machines. Espresso machines use a mixture of high-pressure steam and water to quickly pass through the coffee layer, instantly extracting the coffee. This results in coffee with a high temperature, low caffeine and other impurities, and a rich flavor.

[0003] The traditional steps for preparing espresso are as follows: first, use a coffee maker to collect coffee grounds, then invert the coffee maker onto the funnel to fill it with coffee grounds, then use a coffee maker to even out the grounds, and finally use a tamper to tamp the grounds to ensure that the coffee grounds are evenly distributed and fully extracted. The process is quite complicated.

[0004] To address this, Chinese patent application CN202210039629.1, entitled "Two-in-One Powder Receiver," discloses a two-in-one powder receiver, comprising a cup body and a powder dispensing and pressing part; the cup body is hollow and open at one end, the powder dispensing and pressing part is movably disposed within the cup body, and at least a portion of the outer side of the powder dispensing and pressing part is attached to the inner wall of the cup body; the powder dispensing and pressing part is connected to a driving component, which controls the movement or rotation of the powder dispensing and pressing part, thereby speeding up the operation, avoiding the inconvenience of changing tools, and making it more convenient to use.

[0005] However, for the above solution, when the powder dispensing needle and the tamp hammer are needed to perform powder dispensing and tamping operations respectively, the built-in powder dispensing needle and tamp hammer need to be replaced manually. It is impossible to complete the powder receiving, dispensing and tamping operations in one go. The operation is complicated and the coffee powder is difficult to clean up when it is scattered. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a powder receiver that can perform powder receiving, powder distribution and powder pressing operations in one go, in light of the current state of the technology.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a powder receiving device, including...

[0008] The powder cup is hollow inside and has an open top.

[0009] A powder-pressing hammer, axially movable within the powder-receiving cup, has a powder-pressing surface at its top; and

[0010] A drive shaft passes through the bottom wall of the powder receiving cup, and its top end is coaxially connected to the powder pressing hammer.

[0011] The feature is that it also includes a powder dispensing needle, which includes a main body part disposed in the powder receiving cup and movably sleeved on the outer periphery of the drive shaft along the axial direction, and multiple needle parts spaced apart on the top of the main body part. The powder pressing hammer has a through hole for corresponding to the needle parts and for the corresponding needle parts to pass through.

[0012] The powder-pressing hammer has a first position, a second position, and a third position arranged sequentially from bottom to top during axial movement, so that the powder receiver has at least three states:

[0013] In the powder receiving state, the powder pressing hammer is in the first position and is housed in the powder receiving cup;

[0014] In the powder application state, the powder pressing hammer is in the second position and is housed in the powder receiving cup, and the needle of the powder application needle passes through the corresponding perforation and extends out of the opening of the powder receiving cup.

[0015] In the powder pressing state, the powder pressing hammer is in the third position, and the powder pressing surface extends outward from the opening of the powder receiving cup, while the needle part of the powder dispensing needle is retracted into the powder pressing surface.

[0016] To facilitate the automatic extension and retraction of the powder-applying needle as the powder-pressing hammer moves from the first position to the third position, it also includes...

[0017] A limiting component is used to limit the powder dispensing needle and the powder pressing hammer as the powder pressing hammer moves from the first position to the second position; and

[0018] An elastic element acts between the powder-dispensing needle and the powder-pressing hammer, so that the main body of the powder-dispensing needle always tends to move away from the powder-pressing hammer.

[0019] During the process of the powder pressing hammer moving from the first position to the second position, the powder dispensing needle can overcome the elastic force of the elastic element and move synchronously with the powder pressing hammer under the limiting action of the limiting component.

[0020] During the process of the powder pressing hammer moving from the second position to the third position, the limiting component releases the limiting of the powder dispensing needle, so that the main body of the powder dispensing needle can gradually move away from the powder pressing hammer under the elastic force of the elastic element.

[0021] In order to limit the powder dispensing needle and the powder pressing hammer during the movement of the powder pressing hammer from the first position to the second position, the limiting component includes a first magnetic element installed on the powder pressing hammer and a second magnetic element installed on the powder dispensing needle.

[0022] During the process of the powder pressing hammer moving from the first position to the second position, the first magnetic component and the second magnetic component attract each other.

[0023] As the powder-pressing hammer moves from the second position to the third position, the first magnetic component and the second magnetic component gradually move away from each other.

[0024] To facilitate the automatic release of the limiting component when the powder pressing hammer moves from the second position toward the third position, the powder dispensing needle also includes a bushing located at the bottom of the main body. The bushing is axially movable and fitted around the outer periphery of the drive shaft. The bottom wall of the powder receiving cup has an mounting sleeve for the bushing to pass through, and the bottom end of the bushing has a limiting ring.

[0025] In the powder-spreading state, the limiting ring abuts against the end face of the mounting cylinder so that the first magnetic component can disengage from the second magnetic component when the powder-pressing hammer just leaves the second position and moves toward the third position.

[0026] To facilitate the installation of the first and second magnetic components, the drive shaft has an internal shaft hole, and the bottom of the powder-pressing hammer is provided with a first mounting post that extends into the shaft hole. The shaft hole is provided with a second mounting post that connects to the bushing. The first and second mounting posts are respectively provided with a first mounting groove for the first magnetic component to be engaged and a second mounting groove for the second magnetic component to be engaged.

[0027] In order to connect the second mounting post and the bushing, the peripheral wall of the drive shaft has a relief groove that extends axially and communicates with the shaft hole. The peripheral wall of the second mounting post is provided with a connecting arm that protrudes outward and passes through the relief groove to connect with the bushing.

[0028] To facilitate the installation of the elastic element, the elastic element is a compression spring, which is housed in the shaft hole and sleeved on the outer periphery of the first mounting post and the second mounting post, with the two ends of the compression spring respectively abutting against the opposite surfaces of the powder-pressing hammer and the connecting arm.

[0029] In order to limit the degree of inward retraction of the powder needle relative to the powder pressing hammer, the bottom end of the drive shaft has a gripping part, and the limiting ring is limited between the mounting cylinder and the gripping part. In the powder pressing state, the limiting ring abuts against the gripping part.

[0030] To ensure that the powder receiving cup has a sufficiently large volume when receiving powder, the main body of the powder dispensing needle is sandwiched between the bottom wall of the powder receiving cup and the powder pressing hammer when receiving powder.

[0031] To facilitate the cooperation between the powder receiving device and the funnel, the powder receiving cup can be interlocked with the funnel. The outer peripheral wall of the funnel has at least two positioning blocks arranged at intervals along its circumference. The top edge of the powder receiving cup has at least two positioning seats corresponding to the positioning blocks. The inner side of each positioning seat has a positioning groove that opens in the same direction of rotation for the corresponding positioning block to be rotated and inserted.

[0032] Compared with the prior art, the advantages of this utility model are as follows: By setting a powder dispensing needle that can move relative to the tamper, the powder receiver has at least three states: In the powder receiving state, the tamper is in the first position and is housed in the powder receiving cup, and the powder receiving cup can be used to collect coffee powder to complete the powder receiving operation; In the powder dispensing state, the tamper is in the second position and is housed in the powder receiving cup, and the needle of the powder dispensing needle passes through the corresponding perforation and extends out of the opening of the powder receiving cup, and rotating the tamper drives the powder dispensing needle to rotate synchronously to complete the powder dispensing operation; In the powder tamping state, the tamper is in the third position, and the tamping surface extends out of the opening of the powder receiving cup, and the needle of the powder dispensing needle retracts into the tamping surface, and rotating and pressing the tamping hammer can complete the powder tamping operation. It can be seen that this solution can realize the powder receiving, powder dispensing and powder tamping operations in one go, without the need to change the powder dispensing needle and tamper during the operation, which is simple to operate and can avoid coffee powder scattering.

[0043] like Figures 1 to 8 The image shows a preferred embodiment of the powder receiving device of this utility model. The powder receiving device includes a powder receiving cup 1, a powder pressing hammer 2, a drive shaft 3, a powder distributing needle 4, a limiting component 5, and an elastic element 6.

[0044] The powder receiving cup 1 is hollow inside and has an open top 11; the bottom wall of the powder receiving cup 1 has an installation cylinder 12; the powder receiving cup 1 can be interlocked with the funnel 10; the outer peripheral wall of the funnel 10 has two positioning blocks 101 arranged at intervals along its circumference; the top edge of the powder receiving cup 1 has two positioning seats 13 corresponding to the positioning blocks 101; the inner side of each positioning seat 13 has a positioning groove 131 opening in the same direction of rotation, for the corresponding positioning block 101 to be rotated and inserted.

[0045] The powder pressing hammer 2 is movably disposed within the powder receiving cup 1 along the axial direction. Specifically, the top of the powder pressing hammer 2 has a powder pressing surface 21; multiple spaced through holes 22 are provided through the powder pressing hammer 2 along the axial direction; a first mounting post 23 is provided at the middle position of the bottom of the powder pressing hammer 2, and a first mounting groove 231 is provided on the bottom wall of the first mounting post 23.

[0046] The drive shaft 3 passes through the bottom wall of the powder receiving cup 1, and its top end is coaxially connected to the powder pressing hammer 2. Specifically, the drive shaft 3 has a shaft hole 31 inside, and the aforementioned first mounting post 23 extends into the shaft hole 31; the peripheral wall of the drive shaft 3 has a relief groove 32 that extends axially and communicates with the shaft hole 31; the bottom end of the drive shaft 3 has a gripping part 33.

[0047] The powder-dispensing needle 4 includes a main body 41, needles 42, a bushing 43, and a second mounting post 44. Specifically, the main body 41 is located inside the powder receiving cup 1 and is axially movable around the outer periphery of the drive shaft 3; multiple needles 42 are spaced apart on the top of the main body 41 and correspond one-to-one with the aforementioned through holes 22, with each needle 42 able to pass through the corresponding through hole 22; the bushing 43 is located at the middle position of the bottom of the main body 41, passes through the aforementioned mounting sleeve 12, and is axially movable around the outer periphery of the drive shaft 3, with a limiting ring at the bottom end of the bushing 43. 431, the limiting ring 431 is limited between the mounting cylinder 12 and the gripping part 33, and is used to limit the range of motion of the entire powder needle 4; the second mounting post 44 is provided in the shaft hole 31 and is located below the first mounting post 23. The top wall of the second mounting post 44 is provided with a second mounting groove 441, and the peripheral wall of the second mounting post 44 is provided with a connecting arm 442 protruding outward. The connecting arm 442 passes through the relief groove 32 and connects to the bushing 43.

[0048] The limiting component 5 includes a first magnetic element 51 installed in the first mounting groove 231 and a second magnetic element 52 installed in the second mounting groove 441.

[0049] The elastic element 6 is a compression spring, which is housed in the shaft hole 31 and sleeved on the outer periphery of the first mounting post 23 and the second mounting post 44. The two ends of the compression spring abut against the opposite surfaces of the powder pressing hammer 2 and the connecting arm 442, so that the main body 41 of the powder dispensing needle 4 always tends to move away from the powder pressing hammer 2.

[0050] The aforementioned powder-pressing hammer 2 has a first position, a second position, and a third position arranged sequentially from bottom to top during axial movement, so that the powder receiver has at least three states:

[0051] In the powder receiving state, such as Figure 1 and Figure 4 As shown, the powder pressing hammer 2 is in the first position and is housed in the powder receiving cup 1, and the main body 41 of the powder dispensing needle 4 is sandwiched between the bottom wall of the powder receiving cup 1 and the powder pressing hammer 2.

[0052] In powder form, such as Figure 5 and Figure 6 As shown, the powder pressing hammer 2 is in the second position and is housed in the powder receiving cup 1. The needle part 42 of the powder dispensing needle 4 passes through the corresponding perforation 22 and extends outward from the opening 11 of the powder receiving cup 1, and the limiting ring 431 abuts against the end face of the mounting cylinder 12.

[0053] In the pressed powder state, such as Figure 7 and Figure 8 As shown, the powder pressing hammer 2 is in the third position, and the powder pressing surface 21 extends outward from the opening 11 of the powder receiving cup 1. The needle part 42 of the powder dispensing needle 4 is retracted into the powder pressing surface 21, and the limiting ring 431 abuts against the gripping part 33.

[0054] During the process of the powder pressing hammer 2 moving from the first position to the second position, the first magnetic element 51 and the second magnetic element 52 attract each other to limit the powder dispensing needle 4 and the powder pressing hammer 2, so that the powder dispensing needle 4 can overcome the elastic force of the elastic element 6 and move synchronously with the powder pressing hammer 2.

[0055] As the powder-pressing hammer 2 moves from the second position to the third position, the first magnetic element 51 and the second magnetic element 52 gradually move away from each other and release the restriction on the powder-dispensing needle 4, so that the main body 41 of the powder-dispensing needle 4 can gradually move away from the powder-pressing hammer 2 under the elastic force of the elastic element 6.

[0056] It should be noted that since the limiting ring 431 abuts against the end face of the mounting cylinder 12 in the powder dispensing state, the first magnetic element 51 can disengage from the second magnetic element 52 when the powder pressing hammer 2 just leaves the second position and moves toward the third position.

[0057] The working principle of this embodiment is as follows: During operation,

[0058] (1) First, turn the powder receiver upright and switch it to powder receiving mode. At this time, as follows: Figure 1 and Figure 4 As shown, the opening 11 of the coffee cup 1 faces upward, the tamping hammer 2 is in the first position and is housed in the coffee cup 1, and the main body 41 of the coffee needle 4 is clamped between the bottom wall of the coffee cup 1 and the tamping hammer 2. Then, the coffee cup 1 is used to collect coffee powder, thereby completing the coffee collection operation.

[0059] (2) Then, align the positioning groove 131 on the powder cup 1 with the corresponding positioning block 101 of the funnel 10 and rotate it into place. Then, invert the powder collector so that the coffee powder in the powder cup 1 is poured into the funnel 10.

[0060] (3) Then, the pressing grip 33 drives the powder-pressing hammer 2 from the first position to the second position via the drive shaft 3. During this process, the first magnetic element 51 and the second magnetic element 52 attract each other, thereby limiting the powder-dispensing needle 4 and the powder-pressing hammer 2, so that the powder-dispensing needle 4 can overcome the elastic force of the elastic element 6 and move synchronously with the powder-pressing hammer 2 until the limiting ring 431 abuts against the end face of the mounting cylinder 12. At this time, if Figure 5 and Figure 6 As shown, the coffee dispenser is in the coffee dispensing state, the tamping hammer 2 is in the second position and is housed in the coffee dispensing cup 1, the needle part 42 of the dispensing needle 4 passes through the corresponding perforation 22 and extends out of the opening 11 of the coffee dispensing cup 1 and into the funnel 10. Then, the grip 33 is rotated to drive the dispensing needle 4 to rotate through the drive shaft 3 and the tamping hammer 2, so that the needle part 42 of the dispensing needle 4 stirs the coffee powder in the funnel 10, thereby completing the coffee dispensing operation.

[0061] (4) Then, continue pressing down the gripping part 33 to drive the powder pressing hammer 2 from the second position to the third position via the drive shaft. When the powder pressing hammer 2 just leaves the second position, the limiting ring 431 abuts against the end face of the mounting cylinder 12, preventing the powder dispensing needle 4 from moving further down. This causes the first magnetic element 51 and the second magnetic element 52 to disengage and release the limiting on the powder dispensing needle 4, so that the main body 41 of the powder dispensing needle 4 can gradually move away from the powder pressing hammer 2 under the elastic force of the elastic element 6 until the limiting ring 431 abuts against the gripping part 33. At this time, the needle part 42 of the powder dispensing needle 4 is retracted into the powder pressing surface 21 to avoid affecting the subsequent powder pressing operation. As the powder pressing hammer 2 continues to move down, the constraint relationship between the gripping part 33 and the limiting ring 431 will drive the powder dispensing needle 4 to move down synchronously until the powder pressing hammer 2 moves to the third position. At this time, if Figure 7 and Figure 8 As shown, the coffee maker is in the tamping state, with the tamping surface 21 extending out of the opening 11 of the coffee maker cup 1 and into the funnel 10. Then, the gripping part 33 is rotated and pressed down, which drives the tamping hammer 2 to rotate and compact the coffee powder in the funnel 10 through the drive shaft 3, thereby completing the tamping operation.
