[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example 1: Please refer to Figures 1-2 A water mist spraying mechanism for a coffee grinder bean feeding hopper includes a bean hopper body 1 and a bean feeding cap 2. The cap 2 is installed on the top of the bean hopper body 1, and a bean feeding hopper bracket 6 is snapped onto the bottom of the bean hopper body 1. A rotating component 3, a water supply component 4, and a sealing component 5 are provided inside the bean hopper body 1. The rotating component 3 is located inside the bean hopper body 1, the water supply component 4 is installed on one side of the bean hopper body 1, and the sealing component 5 is located on the rotating component 3.

[0017] The lower cover 301 of the bean collection compartment in the rotating assembly 3 has a mounting hole 302 in the middle, and a rotating sleeve 303 is installed outside the mounting hole 302. The lower cover 301 of the bean collection compartment is installed at the bottom of the bean collection body 1.

[0018] A rotating shaft 304 is fitted inside the rotating sleeve 303 of the rotating assembly 3. The rotating shaft 304 is installed in the mounting hole 302 and is driven by a drive device.

[0019] In use, first open the bean feeding cap 2 installed on the top of the bean hopper body 1, pour an appropriate amount of coffee beans to be ground into the bean hopper body 1, and then close the bean feeding cap 2 to ensure that the interior of the bean hopper body 1 forms a relatively closed space to prevent coffee beans from falling during subsequent conveying. After starting the grinder, the rotating component 3 starts to work under the drive of the drive device. Since the rotating shaft 304 is appropriately matched and connected in the rotating sleeve shaft 303, and the rotating sleeve shaft 303 is fixedly installed outside the mounting hole 302 in the middle of the bean collection chamber lower cover 301, the rotating shaft 304 will rotate stably along the axial direction of the mounting hole 302, and simultaneously drive the rotating sleeve shaft 303 to rotate. The bean collection chamber lower cover 301 is installed at the bottom of the bean hopper body 1, and its top is connected to the interior of the bean hopper body 1. During rotation, the combination structure of the rotating sleeve shaft 303 and the rotating shaft 304 will push the coffee beans in the bean hopper body 1, guiding the coffee beans to move towards the bottom of the bean hopper body 1, preparing them for subsequent entry into the bean feeding chamber support 6 and the grinding process.

[0020] Example 2: Based on Example 1, please refer to... Figures 2-3A water supply pipe 402 is installed on one side of the water tank 401 in the water supply assembly 4. The water supply pipe 402 is fixedly installed on the atomizer 403. The atomizer 403 is installed on one side of the lower cover 301 of the bean collection chamber.

[0021] Before starting the grinder, check the water level in the water tank 401 of the water supply assembly 4. If the water level is insufficient, add water to the water tank 401 to ensure the subsequent water mist spraying needs. When the rotating assembly 3 moves the coffee beans towards the lower cover 301 of the bean collection chamber, the water supply assembly 4 starts simultaneously. The water in the water tank 401 is stably delivered to the atomizer 403 through the water supply pipe 402 installed on one side under its own gravity and with the assistance of the conveying mechanism. Since the water supply pipe 402 is fixedly installed on the atomizer 403, it can prevent the pipe from falling off or shifting during the water flow process, ensuring that the water flow continuously and stably enters the atomizer 403. After the atomizer 403 is powered on, it converts the water into fine water mist. The water mist can be sprayed directly onto the surface of the coffee beans passing through this point, while ensuring that the coffee beans are evenly contacted by the water mist before entering the grinding stage. The water mist neutralizes the static electricity on the surface of the coffee beans, preparing for the reduction of coffee powder scattering in the later stage. It can also slow down the heating rate of the coffee beans during grinding by moderately humidifying them.

[0022] Example 3: Based on Example 2, please refer to... Figures 3-4 The sealing rubber 501 in the sealing assembly 5 is installed in the fixing groove 502 inside the bean feeding bin bracket 6. A mounting half groove 503 is provided on one side end of the sealing rubber 501. A rotating shaft 304 is installed in the mounting half groove 503. The upper part of the sealing rubber 501 is installed in the fixing hole 507 in the lower cover 301 of the bean collecting bin.

[0023] The second sealing ring 504 in the sealing assembly 5 is mounted on the protrusion 505 on the top of the sealing rubber 501, and a buffer layer 506 is provided on the second sealing ring 504.

[0024] During use, as the atomizer 403 of the water delivery assembly 4 sprays water mist onto the coffee beans, the sealing assembly 5 simultaneously performs its sealing function to prevent water mist from seeping into other structures inside the grinder through the gaps between components. The sealing rubber 501 is fixed by the fixing groove 502 inside the bean delivery hopper bracket 6, preventing the sealing rubber 501 from shifting during equipment operation. The mounting half-groove 503 at one end of the sealing rubber 501 wraps around the outside of the rotating shaft 304, tightly fitting the outer circumference of the rotating shaft 304 and preventing water mist from seeping from the rotating shaft 304 and the lower cover 301 of the bean collection hopper. To prevent water from seeping into the bean feeder, the upper part of the sealing rubber 501 is installed in the secure hole 507 in the bean collection chamber lower cover 301, further enhancing the connection and sealing between the sealing rubber 501 and the bean collection chamber lower cover 301, forming the first line of defense. The second sealing ring 504 installed on the top protrusion 505 of the sealing rubber 501 will be in close contact with the bottom surface of the bean collection chamber lower cover 301. This double sealing structure can effectively prevent water mist from seeping into the bean feeder bracket 6 and other electrical components of the grinder. After grinding, simply open the bean feeder cap 2 to pour out the powder.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
