[0026] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0027] like Figure 1-Figure 6As shown, a feed cleaning structure and a coffee machine are provided, the feed cleaning structure comprises a grinding assembly 1 and a feed cleaning assembly 2 detachably mounted on the grinding assembly 1, the grinding assembly 1 comprises a grinding chamber 101, the feed cleaning assembly 2 comprises a pressing member 201 and a cleaning seat 202, an elastic reset member 203 is provided between the pressing member 201 and the cleaning seat 202, the cleaning seat 202 is inserted into the grinding chamber 101, and the elastic reset member 203 is compressed or released according to the capacity of coffee beans in the grinding chamber 101, so that the pressing member 201 pushes the coffee beans upward or downward.

[0028] Specifically, the feed cleaning component 2 can be easily installed on the grinding component 1 and can be disassembled and cleaned at any time during use, ensuring the cleanliness of the inside of the grinding chamber 101; the matching design of the clamping member 201 and the cleaning seat 202 is also very reasonable. The clamping member 201 can push the coffee beans under the action of the elastic reset member 203, so as to ensure that the coffee beans are evenly stressed during the grinding process, and the ground coffee powder particles are also finer and more uniform, thereby improving the extraction effect of the coffee machine; the cleaning seat 202 rotates with the grinding component 1 to avoid residual coffee powder and coffee beans.

[0029] Further, if Figure 1 , Figure 3 and Figure 4 As shown, one end of the elastic reset member 203 abuts against the pressing member 201 , and the other end of the elastic reset member 203 abuts against the cleaning seat 202 .

[0030] Specifically, the elastic reset member 203 is compressed or released according to the capacity of the coffee beans in the grinding chamber 101. When the coffee beans are filled in the grinding chamber 101, the cleaning seat 202 squeezes the elastic reset member 203 to deform, ensuring that the coffee beans are evenly stressed during the grinding process. The ground coffee powder particles are also finer and more uniform, thereby improving the extraction effect of the coffee machine; when the coffee beans gradually decrease in the grinding chamber 101, the elastic reset member 203 is released to restore the cleaning seat 202 to its original position.

[0031] Further, if Figure 1-Figure 4 As shown, the pressing member 201 is provided with a pushing column 2011 for pushing coffee beans, and the cleaning seat 202 is provided with an annular inner cylinder 2021, and the pushing column 2011 slides up and down along the annular inner cylinder 2021.

[0032] Specifically, a pushing column 2011 is arranged above the clamping member 201, and the pushing column 2011 can slide up and down within a certain range to push the movement of the clamping member 201; an annular inner cylinder 2021 can be provided on the cleaning seat 202, and the annular inner cylinder 2021 can cooperate with the edge of the clamping member 201 to play a guiding role to avoid displacement during the up and down sliding process.

[0033] Further, if Figure 4 As shown, the annular inner cylinder 2021 is provided with a positioning rib 2021a, and the pushing column 2011 is provided with a slot 2011b that matches the positioning rib 2021a. When the pressing member 201 is pushed downward a certain distance, the inner wall of the pressing member 201 abuts against the positioning rib 2021a.

[0034] Specifically, a positioning rib 2021a is added to the annular inner cylinder 2021 to more accurately control the movement trajectory of the clamping member 201; a slot 2011b that cooperates with the positioning rib 2021a is also added to the push column 2011. When the clamping member 201 is pushed down a certain distance, it can be accurately brought into contact with the positioning rib 2021a, thereby achieving precise positioning and control, and preventing the position of the clamping member 201 from being offset due to irregular movement, which affects the grinding accuracy and efficiency. Such a design can not only improve the cleaning effect, but also reduce unnecessary interference to the grinding system and improve the operating efficiency of the system. At the same time, it can also reduce the difficulty of maintenance, making the cleaning work simpler and more efficient.

[0035] Further, if Figure 2-Figure 4 As shown, a mounting cavity 2022 is formed between the cleaning seat 202 and the annular inner cylinder 2021 , and the other end of the elastic reset member 203 is placed in the mounting cavity 2022 .

[0036] By adopting the above arrangement, the elastic reset member 203 can be stably installed on the installation cavity 2022 .

[0037] Further, if Figure 3 and Figure 4 As shown, a support rib 2022c is provided in the installation cavity 2022, and the other end of the elastic reset member 203 abuts against the support rib 2022c.

[0038] Further, if Figure 3 and Figure 5 As shown, a positioning buckle 2012 is provided on the pressing member 201 , and a step 2023 cooperating with the positioning buckle 2012 is provided on the top of the cleaning seat 202 . When the pressing member 201 moves upward for a certain distance, the positioning buckle 2012 cooperates with the step 2023 .

[0039] Specifically, the above arrangement can realize accurate positioning of the pressing member 201 at the top of the cleaning seat 202, further improving the cleaning efficiency and precision of the cleaning seat. At the same time, the step 2023 that cooperates with the positioning buckle 2012 can also ensure the stability and consistency of the cleaning seat 202 when the pressing member 201 moves upward. Such a design can not only effectively prevent the movement deviation of the pressing member 201, but also help the regular maintenance and management of the cleaning seat 202.

[0040] Further, if Figure 1, Figure 2 and Figure 6 As shown, the grinding assembly 1 includes a powder sweeping plate 102 , and a cleaning portion 2024 cooperating with the powder sweeping plate 102 is provided on the cleaning seat 202 .

[0041] Specifically, the coordinated design of the powder sweeping plate 102 and the cleaning portion 2024 can further improve the cleaning efficiency of the coffee machine.

[0042] Furthermore, the grinding assembly 1 further includes a grinding piece 103 and a driving motor 104 for driving the grinding piece 103 to rotate. The driving motor 104 is rotatably connected to the grinding piece 103 and the powder sweeping plate 102 .

[0043] Furthermore, the elastic return member 203 is a spring.

[0044] Specifically, when the elastic reset member 203 is a spring, the spring has good elasticity and durability, can withstand greater force and maintain a stable shape; during use, when the coffee beans in the grinding chamber 101 are full, the pressing member 201 is pushed upward a certain distance, the spring is compressed, and when the coffee beans in the grinding chamber 101 gradually decrease, the cleaning seat 202 is restored to its original position under the action of the spring.

[0045] It should be noted that the elastic reset member 203 may also be an elastic silicone member.

[0046] like Figure 7 As shown, a coffee machine includes a body 3, a feed cleaning structure is provided on the body 3, a guide groove 301 is provided on the top of the body 3, and the feed cleaning component 2 also includes a guide part 204, and the feed cleaning component 2 is fixedly installed on the body 3 along the guide groove 301 through the guide part 204.

[0047] The feed cleaning component 2 is fixedly mounted on the machine body 3 along the guide groove 301 through the guide portion 204, which can achieve accurate installation and positioning of the feed cleaning component 2, while also ensuring its perfect fit with the machine body 3, avoiding unnecessary shaking or deviation during use, which would affect the cleaning efficiency and cleaning effect.

[0048] In addition, the design of the guide groove 301 can also help the feed cleaning assembly 2 to better cooperate with the machine body 3, thereby improving the efficiency and convenience of the overall cleaning work. At the same time, by providing the feed cleaning structure on the machine body 3, the machine body 3 can also be effectively protected to avoid damage to it during the cleaning process, while also improving the safety and environmental protection of the cleaning work.

[0049] It should be noted that the coffee machine can be a bean-grinding coffee machine or a fully automatic coffee machine.
