[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings. Obviously, the described embodiments are only preferred embodiments of the present utility model.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be a middle element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be a middle element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manners.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific implementation manners and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] Referring to the attached Figures 1 to 8 , in an inlet valve for a coffee machine and a coffee machine in an embodiment of the present utility model, there is included a valve body 10. A water flow channel and a water inlet valve core 20 are provided inside the valve body 10. The upper end of the valve body 10 has a water inlet end, and the lower end of the valve body 10 has a water outlet end. The water flow channel communicates the water inlet end and the water outlet end; a water filter basket 11 is installed in the water flow channel. The water inlet end is located above the water filter basket 11, and the water outlet end is located below the water filter basket 11; the water filter basket 11 includes a water filter plate 111, and a plurality of water filter holes are provided on the water filter plate 111. Among them, the water filter plate 111 is inclined and arranged inside the valve body 10.

[0030] Thus, by arranging the water filtering plate 111 in an inclined manner, dust will flow to the bottom end of the water filtering plate, thereby effectively avoiding the blockage of the water filtering holes by dust. Moreover, water will flow on the water filtering plate 111 and be buffered, which can further improve the filtering effect. Generally, the inclination angle of the water filtering plate 111 is 25 to 50 degrees, preferably 30 degrees.

[0031] Furthermore, the valve body 10 includes an upper cover 101 and a lower cover 102. The upper cover 101 and the lower cover 102 are assembled to form the valve body 10, and a sealing ring 103 is arranged between the upper cover 101 and the lower cover 102; preferably, an installation groove for installing the sealing ring 103 is arranged on the upper end surface of the lower cover 102.

[0032] As Figure 3 shown, a sealing cover 30 is arranged at the upper end of the upper cover 101. There is a water inlet hole at the center of the sealing cover 30. The water inlet valve core 20 is located below the water inlet hole and is used to close the water inlet hole; and, a first return spring 21 for driving the water inlet valve core 20 to move upward to close the water inlet hole is arranged at the water inlet valve core 20. As Figure 4 shown, during use, the water tank is placed above the water inlet valve core 20 and presses the water inlet valve core 20. Thus, a water inlet gap is formed between the water inlet valve core 20 and the sealing cover 30, so that the water in the water tank can enter the valve body 10.

[0033] Furthermore, the upper cover 101 is provided with a water passing hole 1011; the water entering the valve body 10 passes through the water passing hole 1011 and then falls into the water filtering basket 11. Further, the water filtering basket 11 includes an annular portion 112, and the water filtering plate 111 is located at the lower end of the annular portion 112; a stop edge extends outward from the upper end of the annular portion 112 and is installed in the valve body 10 through the stop edge.

[0034] Preferably, the sealing cover 30 is made of silica gel or rubber, so as to ensure the good elasticity of the sealing cover 30. It should be noted that: due to the tension between water molecules, during long-term use, the tension of water molecules will gradually affect the speed of water flowing down from the water filtering plate 111. After the speed decreases, a large amount of steam is generated during the heating process, which may cause the temperature controller on the heating tube to trip early and affect the normal operation. In this application, the water filtering plate 111 is arranged in an inclined manner, so that there is a buffer area for the water flowing down from the upper cover 101, which can effectively prevent such events from occurring. At the same time, when the water tank is suddenly removed during the use of the machine, during the process of suddenly removing the water tank, since there is a small amount of water remaining in the valve body 10, in order to prevent the water in the valve body 10 from suddenly flowing back, after the water tank is removed, the water inlet valve core 20 automatically resets due to the first return spring 21, so that the water inlet valve core 20 is closed with the sealing cover 30 to prevent the water from flowing back.

[0035] This embodiment also discloses a coffee machine 50, which includes a body. An inlet valve and a water tank are installed on the body, and the inlet valve is the aforementioned inlet valve for a coffee machine.

[0036] The design focus of the present utility model is that, mainly by obliquely arranging a water filter plate in the valve body, liquid water can buffer and flow on the water filter plate, thereby improving the filtering effect of liquid water and well playing the role of avoiding blockage; furthermore, since the water filter plate is obliquely arranged, even if it is blocked after long-term use, there is a process of slow blockage, that is, starting from the water filter holes at the bottom of the water filter plate and gradually blocking, giving a reminder to the user to clean; secondly, a first return spring is provided for the rebound of the valve core, thereby ensuring the anti-backflow function of the valve body, and having the advantages of simple and ingenious structure and low manufacturing cost.

[0037] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
