[0031] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0032] For the water tank structure of the coffee machine, please refer to Figures 1-6 As shown in the figure, it includes: a water tank 100 and a water tank base 200. The water tank 100 can be taken out from the water tank base 200 and the water tank 100 can be installed on the water tank base 200.

[0033] As Figure 1 shown, the water tank structure is independent of the coffee machine main unit 300. The water tank base 200 of the water tank structure and the coffee machine main unit 300 are connected by a flexible pipe 400, so that the water tank base 200 can be placed at different positions relative to the coffee machine main unit 300, making it more flexible to use. At the same time, the volume of the coffee machine main unit 300 is reduced, and the limitation of the coffee machine main unit 300 on the volume of the water tank 100 is also reduced.

[0034] Continuing as Figure 1 shown, Figure 1 in the figure, the water tank structure is located on the right side of the coffee machine main unit 300. According to the usage requirements, the water tank structure can be placed on the left side or the rear side of the coffee machine main unit 300, etc., but the placement range of the water tank structure is limited by the length of the flexible pipe 400.

[0035] The water tank base 200 is provided with a water outlet. One end of the flexible pipe 400 is connected to the water outlet, and the other end is connected to the water inlet of the coffee machine main unit 300. The water in the water tank 100 flows through the water outlet of the water tank base 200, the flexible pipe 400, the water inlet of the coffee machine main unit 300, and finally flows into the water circuit system of the coffee machine main unit 300.

[0036] A water storage cavity is formed in the water tank 100. A water tank cover is provided at the top of the water tank 100. Opening the water tank cover facilitates water replenishment and cleaning of the water tank 100; a through hole is provided at the bottom of the water tank 100, and a leak-proof valve 110 is installed in the through hole. The water tank base 200 is provided with a trigger structure for triggering the leak-proof valve 110;

[0037] After the water tank 100 is removed from the water tank base 200, the leak - stopping valve 110 closes, and the water in the water tank 100 cannot flow out through the through - hole. After the water tank 100 is installed on the water tank base 200, the leak - stopping valve 110 is triggered by the triggering structure to open. The water outlet of the water tank base 200 is communicated with the water storage cavity of the water tank 100, and the water in the water tank 100 flows into the water tank base 200 through the through - hole and flows towards the water outlet.

[0038] Between the water tank 100 and the water tank base 200, one of them is provided with a movable latch 510, and the other is provided with a buckle position 520. The water tank 100 and the water tank base 200 are limited by the cooperation of the movable latch 510 and the buckle position 520, so that the water tank 100 is restricted in the water tank base 200. After assembly, the stability is good, and it can prevent the water tank 100 from being lifted when the remaining water in the water tank 100 is small, so as to better use up the water in the water tank 100; moreover, even if the water in the water tank 100 is exhausted, the water tank 100 will not be lifted and will not shake.

[0039] In one embodiment, as Figure 5 shown, the water tank base 200 is provided with an installation position 210 with an upward opening, and the bottom of the water tank 100 is received in the installation position 210; specifically, as Figure 2 shown, during assembly, the water tank 100 is directly assembled into the installation position 210 from top to bottom, and the bottom of the water tank 100 is partially received in the installation position 210. After assembly, the stability is good; when disassembling, the water tank 100 can be directly pulled out upward from the installation position 210, and the disassembly is convenient.

[0040] In one embodiment, as Figure 2 shown, the water tank base 200 is provided with a movable latch 510, and the outer side wall of the water tank 100 is provided with a buckle position 520.

[0041] Continuing as Figure 2 shown, the water tank base 200 has an upper cover 201 and a lower cover 202. The upper cover 201 and the lower cover 202 are combined, and the movable latch 510 is installed in the space formed between the upper cover 201 and the lower cover 202; further, as Figure 6 shown, the overall shape of the movable latch 510 is set in a V - shape. The movable latch 510 includes: a mounting portion 511, an elastic portion 512, and a buckling portion 513. The mounting portion 511 is located at the bottom of the V - shape, and the mounting portion 511 is a rotating shaft. The elastic portion 512 and the buckling portion 513 are respectively the two legs of the V - shape; the end of the buckling portion 513 is connected to the mounting portion 511, and an arc - shaped convex platform 514 is formed at the beginning of the buckling portion 513.

[0042] As Figure 3As shown, the movable latch 510 is rotatably assembled to the water tank base 200 through the mounting portion 511. A shaft hole matching the mounting portion 511 should be provided inside the water tank base 200; the arc-shaped boss 514 at the beginning of the latching portion 513 can protrude from the inner side wall of the mounting position 210 to cooperate with the latching position 520 of the water tank 100, and the elastic portion 512 abuts against the inner wall surface of the upper cover 201, and the elastic portion 512 tightly latches the latching portion 513 to the latching position 520.

[0043] Further, the latching position 520 is a groove provided in a circle on the outer wall of the water tank 100, and the inner wall surface of the groove is arc-shaped, which cooperates with the arc-shaped boss 514 of the movable latch 510.

[0044] Further, a hole 211 is provided on the inner side wall of the mounting position 210, and the arc-shaped boss 514 of the movable latch 510 passes through the hole 211 and is latched in the latching position 520 of the water tank 100.

[0045] Even further, as Figures 3-5 shown, the water tank 100 is in a barrel shape, and the cross-sectional shape of the mounting position 210 is circular. In order to enable the arc-shaped boss 514 of the movable latch 510 to pass through the hole 211 and be latched in the latching position 520 of the water tank 100 when the water tank 100 can be mounted on the mounting position 210 at any angle without position alignment, the above-mentioned latching position 520 is set as a circle; of course, the latching position 520 can also be designed as a dot-shaped groove, but this method requires position alignment during installation to ensure that the arc-shaped boss 514 is snapped into the latching position 520; if three movable latches 510 are provided in the water tank base 200, three dot-shaped grooves are provided on the outer side surface of the water tank 100. After the water tank 100 is inserted into the mounting position 210 of the water tank base 200 from top to bottom, the water tank 100 is rotated to make the arc-shaped boss 514 snap into the latching position 520 to realize the limit between the water tank 100 and the water tank base 200;

[0046] Optionally, the water tank 100 can also be designed as a rectangle, then the cross-sectional shape of the mounting position 210 of the water tank base 200 is also a rectangle. If a movable latch 510 is provided for each side of the corresponding rectangle, four movable latches 510 are provided on the water tank base 200. Correspondingly, four dot-shaped grooves are provided on the outer side surface of the water tank 100. No position alignment is required during installation, and the water tank 100 is directly inserted into the mounting position 210 of the base 200 from top to bottom to realize the limit between the water tank 100 and the water tank base 200.

[0047] In one embodiment, the movable latch 510 is installed on the water tank 100. The movable latch 510 is an elastic leg. One end of the elastic leg is connected to the water tank 100, and the other end is provided with an arc-shaped boss protruding outward. Here, protruding outward means protruding outward perpendicular to the central axis of the water tank; and the inner side wall of the installation position is provided with a buckle position. The buckle position is a circular groove provided on the inner side wall of the installation position, and the inner wall surface of the groove is arc-shaped and is matched with the arc-shaped boss of the movable latch.

[0048] Similarly, if the water tank 100 is in a barrel shape, the cross-sectional shape of the installation position 210 is circular, and the buckle position is a circular groove provided on the inner side wall of the installation position.

[0049] Optionally, the buckle position can also be a plurality of dot-shaped grooves provided on the inner side wall of the installation position. After the water tank 100 is assembled in the installation position 210, the water tank 100 is rotated so that the arc-shaped boss of the movable latch is snapped into the groove to realize the limit between the water tank 100 and the water tank base 200.

[0050] Optionally, the water tank 100 can also be designed as a rectangle. Then the cross-sectional shape of the installation position 210 of the water tank base 200 is also a rectangle. An active latch 510 is provided corresponding to each side of the rectangle of the water tank 100. Then the water tank 100 is provided with four active latches 510. Correspondingly, four dot-shaped grooves are provided on the inner side wall of the installation position 210. During installation, no alignment is required. After the water tank 100 is directly inserted into the installation position 210 of the base 200 from top to bottom, the limit between the water tank 100 and the water tank base 200 is realized.

[0051] In one embodiment, the flexible pipe 400 includes: an inner pipe for passing water and a telescopic outer pipe sleeved outside the inner pipe for protection; the inner pipe can be a flexible soft rubber pipe, and the outer pipe can be a corrugated pipe.
