Description

Technical Field

[0001] The present invention belongs to the technical field of coffee machines, and particularly relates to a coffee machine with a flip cover structure. Background Art

[0002] Coffee machines can be classified into drip coffee machines, capsule coffee machines, bean grinding coffee machines, etc. according to whether the coffee beans are ground in the machine. Among them, the coffee capsule contains a fixed amount of coffee powder. After making coffee, the used coffee capsule needs to be taken away from the brewing chamber. For this reason, some coffee machines are provided with an opening at the upper part of the brewing chamber, and a container bracket for holding the coffee capsule or coffee powder / packet enters or leaves the brewing chamber from this opening. A brewing shower head with a flip cover structure is configured on this opening, and the opening or closing of the brewing shower head is controlled by a handle. Before making coffee, open the handle, put the container bracket filled with the coffee capsule or coffee powder / packet into the brewing chamber from the upper opening, and then operate the handle to close the upper opening of the brewing chamber with the brewing shower head, and start coffee extraction. Usually, in order to extract capsule coffee, a puncturing needle that can be retracted and extended up and down is provided in the middle of the brewing shower head. In this way, when the brewing shower head is opened, there will be no accident of cutting the human hand due to the protrusion of the puncturing needle. However, in the existing above-mentioned coffee machines, the action of retracting the puncturing needle into the brewing shower head is synchronized with the flip cover action of the brewing shower head. When the brewing shower head has not completely closed the opening of the brewing chamber, the puncturing needle has already protruded from the brewing shower head, and the closing of the brewing shower head and the telescoping of the puncturing needle cannot be carried out step by step. Summary of the Invention

[0003] The purpose of the present invention is to provide a coffee machine with a flip cover structure. When the upper cover is opened with the handle, the puncturing needle first retracts into the brewing shower head, and then the brewing chamber opening is further opened by flipping the cover; during the closing operation, the upper cover first closes the brewing chamber opening, and then the puncturing needle protrudes from the brewing shower head to solve the problems mentioned in the background art.

[0004] To solve the above technical problems, the present invention is realized through the following technical solutions: A coffee machine with a flip cover structure includes a machine body and an upper cover. The upper cover is hinged to the machine body. The upper cover is provided with a handle and a puncturing needle. The handle rotates relative to the upper cover between a first position and a second position. It is characterized in that: the handle is hinged to the upper cover, a slider, a first groove, and an elastic pressing block are arranged in the upper cover. The slider is connected to the puncturing needle, and the handle directly or indirectly drives the slider to make the puncturing needle slide up and down in the first groove; a pressing tongue is arranged on the slider, and a pressing block actuator is arranged in the machine body. The pressing block actuator is used to touch the elastic pressing block so that after the upper cover is closed, the pressing tongue can cross the elastic pressing block, and after the upper cover is opened, the elastic pressing block prevents the pressing tongue from passing through.

[0005] The elastic pressing block includes a tongue pressing baffle and a compression spring. The compression spring has the potential energy to hold the tongue pressing baffle in the third position, and the pressing block actuator is used to drive the tongue pressing baffle from the third position to the fourth position.

[0006] The tongue pressing baffle includes a baffle portion and a sliding rod. An inner cover is arranged inside the machine body, an upper cover hinge seat is arranged on the inner cover, the upper cover is provided with a sliding rod barrel cavity, the sliding rod is inserted into the sliding rod barrel cavity and extends out of the upper cover into the inner cover, and the pressing block actuator is arranged inside the inner cover.

[0007] The pressing block actuator is a resisting column arranged directly below the sliding rod barrel cavity.

[0008] Both side walls of the upper cover are provided with slider grooves, convex blocks are arranged on both sides of the slider, and the convex blocks extend into the slider grooves to enable the slider to slide back and forth between the fifth position and the sixth position.

[0009] The handle is provided with a side arm, the first and second hinge points are arranged on the side arm, the handle is connected to the upper cover at the first hinge point and is connected with a connecting piece at the second hinge point, the connecting piece is provided with a third hinge point connected to the slider, and the slider is provided with a guiding column which is inserted into the sliding groove on the puncturing needle.

[0010] The baffle portion is provided with a compression spring groove with an open top, and the middle part of the compression spring extends into the compression spring groove.

[0011] The present invention has the following beneficial effects:

[0012] 1. Through the design of the elastic pressing block in the present invention, the slider can only prompt the puncturing needle to extend out of the upper cover when the upper cover is in the closed state. When the upper cover is opened by the handle, the rear tongue of the slider presses against the side wall of the downward-moving elastic pressing block and cannot cross the elastic pressing block, so that the handle is kept in the "uncovered" state and the puncturing needle is kept in the retracted state until the upper cover is closed and the elastic pressing block is lifted.

[0013] 2. The present invention divides the expansion and contraction of the puncturing needle and the opening and closing of the upper cover into two steps. During the whole process of opening the upper cover with the handle, the handle rotates first to retract the puncturing needle into the upper cover (at this time the upper cover is still in the closed state), and then the handle is further pushed to open the upper cover to open the opening of the brewing cavity, so that the container bracket in the brewing cavity can be taken out / put in; during the closing operation, the upper cover first closes the opening of the brewing cavity. At this time, continue to pull the handle to make the puncturing needle extend out of the upper cover and insert into the brewing cavity.

[0014] 3. The spring in the present invention provides an elastic force for the slider, so that the handle has the potential energy to close the cover. When opening the cover, it is necessary to overcome the reverse acting force of the spring, giving the user a good operating feel and experience. Description of the Drawings

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] Please refer to Figures 1-9As shown in the figure, the present invention discloses a coffee machine with a flip - top structure, which includes a body 10 and an upper cover 2. The upper cover 2 is hinged to the body. The upper cover is provided with a handle 1 and a puncturing needle 6. The handle rotates between a first position and a second position relative to the upper cover. The handle 1 is hinged to the upper cover 2. Inside the upper cover, a slider 3, a first groove, and an elastic pressing block 8 are arranged. The slider 3 is connected to the puncturing needle 6. The handle directly or indirectly drives the slider, so that the puncturing needle slides up and down in the first groove. The slider 3 is provided with a tongue - pressing piece 33. Inside the body, a pressing - block actuator is arranged. The pressing - block actuator is used to touch the elastic pressing block 8, so that after the upper cover is closed, the tongue - pressing piece 33 can cross over the elastic pressing block, and after the upper cover is opened, the elastic pressing block prevents the tongue - pressing piece from passing through. Among them, the first groove is arranged on the bottom wall of the upper - cover main body 20. The first groove is a sliding cylinder 23 that penetrates the inside and outside of the upper - cover main body 20. The puncturing needle is installed in the sliding cylinder 23 and slides up and down in the sliding cylinder 23, so as to realize that the end of the puncturing needle extends out of or retracts into the upper - cover main body from the bottom wall of the upper - cover main body, so as to avoid unexpected scratching accidents when the coffee - machine cover is lifted. See Figures 2-3 , on the panel of the upper cover 2, a handle - activity area 210 is set. The handle - activity area 210 is a sunken activity space with a wedge - shaped surface. When the handle is pulled from the first position (parallel to the bottom wall of the upper - cover main body 20, that is, the closed - cover position) to the second position, at this time, the lower wall surface of the handle is close to the wedge - shaped surface of the handle - activity area 210. Due to the pulling of the slider, the puncturing needle 6 is in a retracted state. The pressing - block actuator releases the restraint on the elastic pressing block 8, prompting the elastic pressing block 8 to move downward towards the bottom wall of the upper - cover main body 20. The end of the tongue - pressing piece 33 presses against the side wall of the elastic pressing block 8, resulting in the slider being unable to move to the right, the puncturing needle 6 being unable to extend, and the handle being unable to return to the first position until the upper cover rotates clockwise to the closed - cover position and the pressing - block actuator lifts the elastic pressing block 8. At this time, the slider can cross over the elastic pressing block 8, enabling the puncturing needle 6 to move downward and the handle to be slowly pulled from the second position to the first position.

[0027] The elastic pressing block 8 includes a tongue - pressing baffle and a compression spring 83. The compression spring has the potential energy to keep the tongue - pressing baffle in the third position. The pressing - block actuator is used to drive the tongue - pressing baffle from the third position to the fourth position. The third position is the position that can limit the right - ward movement of the slider, and the fourth position is the position where the tongue - pressing baffle 81 moves upward so that the tongue - pressing piece 33 of the slider can pass through it.

[0028] The tongue - pressing baffle includes a baffle part 81 and a sliding rod 84. Inside the body, an inner cover 5 is arranged. On the inner cover 5, an upper - cover hinge seat 51 is set. The upper cover 2 is provided with a sliding - rod barrel cavity 24. The sliding rod 84 is inserted into the sliding - rod barrel cavity 24 and extends from the upper cover 2 into the inner cover 5. The pressing - block actuator is arranged inside the inner cover 5.

[0029] The pressure block actuator is a post 54 located directly below the slide rod cavity. The inner lid 5 has a pair of upper lid hinges 51, with an arcuate guide rail set between them. This rail set consists of a slide rail mounted on the bottom of the upper lid and a slide groove mounted on a slide groove seat 52, ensuring smooth rotation of the upper lid. A brewing chamber 53 is located at the front of the inner lid. A notch in front of the brewing chamber 53 facilitates access to the brewing holder 9, where the coffee capsule is placed. Stoppers 55 are also located on both side walls of the inner lid to maintain a horizontal position within the inner lid.

[0030] Slider slots 25 are formed on both side walls of the upper cover 2, and protrusions 35 are provided on both sides of the slider 3. The protrusions 35 extend into the slider slots 25, allowing the slider 3 to slide back and forth between a fifth position and a sixth position. The fifth position is when the protrusion 35 is at the left end of the slider slot 25 (near the brewing chamber), and the sixth position is when the protrusion 35 is at the right end of the slider slot 25.

[0031] The handle 1 is provided with side arms with first and second hinge points. The handle is connected to the upper cover at the first hinge point 11 and to the connector 4 at the second hinge point 12. The connector 4 is provided with a third hinge point 42 for connecting to the slider 3. The slider 3 is provided with a guide post 31, which inserts into a slot 61 on the puncture needle 6. The upper cover 2 has first through-holes 22 on either side of the panel. A handle hinge seat is provided adjacent to the first through-holes, with a hinge axis hole 21 defined within the hinge axis hole 21. The handle's first hinge point 11 is mounted on the hinge axis hole 21. The second hinge point 12 extends through the first through-hole 22 and is hingedly connected to the connector 4 at the hinge axis 41. The third hinge point 42 on the connector 4 is hingedly connected to the slider hinge hole 32 of the slider 3. A spring slot 34 is also provided at the front end of the slider 3. A return spring is positioned within the spring slot 34 on one side and presses against the inner wall of the upper cover body 20 on the other side. The return spring has the potential energy to maintain the slider in the sixth position.

[0032] The baffle portion 81 is provided with a compression spring groove 82, the top of which is open, and the middle portion of the compression spring 83 extends into the compression spring groove 82. Figures 8-9 , reference numerals 101, 102, and 103 respectively represent the position changes of the three hinge points, among which the hinge point 101 (refer to the first hinge point 11 of the handle) remains in the same position during the process of opening and closing the lid, while the hinge point 102 (refer to the second hinge point 12) produces angular displacement as the handle is pulled from the first position to the second position. The hinge point 103 (refer to the third hinge point 42) is constrained by the translation of the slider 3, and its relative displacement is on the horizontal plane with the bottom wall of the upper cover. When the moving distance of the hinge point 103 is L1, the moving displacement of the guide column 31 is also L1. At this time, the up and down displacement of the puncture needle 6 is L2, that is, after the guide column 31 moves the stroke of L1, the puncture needle 6 produces a vertical displacement of a distance L2.
