[0039] A grinding device can grind coffee beans or other beans into powder to provide materials for making corresponding beverages. During the grinding process, the grinding device collides with and rubs against the material to be ground. Friction occurs between the material particles, between the particles and the inner wall of the grinder, and these frictions will cause the accumulation of electric charges, thereby generating electrostatic force. At this time, the material particles are prone to adsorb on places such as the grinding chamber and the powder outlet channel under the action of the electrostatic force, and it is also easy to have the situation of powder flying, which seriously affects the user experience. To solve this problem, in the related art, a plasma generator is provided on the grinding device to reduce the static electricity on the material particles, thereby reducing the adsorption and powder flying phenomena. However, there are still adsorption phenomena and powder flying phenomena, which urgently need to be improved.

[0040] In view of this, the present application provides a grinding device, in which a plasma generator is arranged between the powder outlet channel and the impeller. When the impeller rotates, it can generate an air flow. When the generated air flow passes through the plasma generator, it will form a plasma wind. On the one hand, the plasma wind can blow the material particles towards the powder outlet channel, thereby reducing the adsorption phenomenon and the accumulation phenomenon. On the other hand, the plasma wind can eliminate the static electricity on the material particles, thereby reducing the adsorption phenomenon and the powder flying phenomenon.

[0041] In an embodiment of the present application, with reference to Figure 1 and Figure 2 , the above-mentioned grinding device 1 includes a grinding bracket 11, a grinding assembly 12, a powder outlet channel 13, an impeller 14, a plasma generator 15, and a driving assembly 16.

[0042] Among them, a grinding chamber 111 is arranged on the grinding bracket 11; the grinding assembly 12 is arranged in the grinding chamber 111; the powder outlet channel 13 is communicated with the grinding chamber 111; the impeller 14 is arranged below the grinding assembly 12, and the impeller 14 includes a plurality of blades 141; at least one plasma generator 15 is arranged between the powder outlet channel 13 and the impeller 14; the driving assembly 16 is rotatably connected to the grinding assembly 12 and the impeller 14 respectively, and the driving assembly 16 is used to drive the blades 141 to rotate to generate an air flow, and the air flow passes through the plasma generator 15 to form a plasma wind and blows towards the powder outlet channel 13.

[0043] In the technical solution of the present application, the grinding bracket 11 can be used to support or accommodate the grinding chamber 111101. Specifically, the grinding chamber 111 can be formed by a groove formed by the grinding bracket 11, arranged above the grinding bracket 11, and the bottom of the grinding chamber 111 is in a sealed state.

[0044] The grinding chamber 111 can be used to accommodate the grinding assembly 12 and the impeller 14, as well as the material to be ground. The grinding assembly 12 can be used to grind the material to be ground. The ground powdered material will fall to the bottom of the grinding chamber 111 where the impeller 14 is arranged under the action of gravity. The impeller 14 can scrape the ground powdered material and convey it to the powder outlet channel 13. It can be understood that since the impeller 14 is provided with a plurality of blades 141, when the impeller 14 drives the blades 141 to rotate at a high speed, an air flow can be generated, and the air flow can blow the powdered material towards the powder outlet channel 13. The powder outlet channel 13 can be used to output the powdered material outside the grinding device 1.

[0045] The plasma generator 15 can be used to eliminate the static electricity generated by the powdered material during grinding, so as to effectively avoid the accumulation of the powdered material after grinding in the grinding bin 111 and the powder outlet channel 13 due to electrostatic adsorption, thereby improving the adsorption and powder flying phenomena. Specifically, the plasma generator 15 can include a generator body and an electrode end. The generator body is used to provide a high voltage for the electrode end to generate plasma. It can be understood that the generator body is the core component of the plasma generator 15, and the generator body contains all the circuits and control systems required to generate plasma to provide a high voltage suitable for generating plasma. The electrode end is used to receive the high voltage generated by the generator body and release plasma. Specifically, the plasma released by the electrode end can combine with the charged dust particles generated during the grinding process, thereby neutralizing the charges of the dust particles and reducing the mutual attraction between the dust particles, that is, eliminating the static electricity between the dust particles. It can be understood that since at least one plasma generator 15 is provided between the powder outlet channel 13 and the impeller 14, when the impeller 14 rotates to generate an air flow, the generated air flow can form a plasma wind after passing through the plasma generator 15. On the one hand, the plasma wind can blow the material particles towards the powder outlet channel 13, thereby reducing the adsorption phenomenon and the accumulation phenomenon. On the other hand, the plasma wind can eliminate the static electricity on the material particles, thereby reducing the adsorption phenomenon and the powder flying phenomenon.

[0046] The drive assembly 16 can be rotatably connected to the grinding assembly 12 and the impeller 14 respectively. When the drive assembly 16 operates, it can drive the grinding assembly 12 to rotate to grind the material through the connection structure. At the same time, the drive assembly 16 can also drive the impeller 14 to rotate to scrape the ground powdered material and convey it to the powder outlet channel 13, and generate an air flow to blow the powdered material towards the powder outlet channel 13 through the air flow. Specifically, the drive assembly 16 can include a drive motor. A toothed rod can be provided on the motor shaft of the drive motor, and the toothed rod can be meshed with a double gear, and the double gear can be meshed with a shaft gear. Among them, the double gear can be arranged on the grinding bracket 11; the shaft gear can be arranged on the support shaft and is coaxially connected to the grinding assembly 12 and the impeller 14. When the drive motor operates, the motor shaft rotates, driving the toothed rod to rotate, and then the toothed rod drives the double gear to rotate, and the double gear drives the shaft gear to rotate. Thus, the shaft gear drives the grinding assembly 12 and the impeller 14 to rotate to grind the material to be ground, and scrape and convey the ground powder material, and generate an air flow to blow the powder material towards the powder outlet channel 13.

[0047] The grinding device 1 provided by the technical solution of the present application includes a grinding bracket 11, a grinding assembly 12, a powder outlet channel 13, an impeller 14, a plasma generator 15, and a driving assembly 16. In the embodiment of the present application, a plasma generator 15 is arranged between the powder outlet channel 13 and the impeller 14. When the impeller 14 rotates, it can generate an air flow. When the generated air flow passes through the plasma generator 15, a plasma wind will be formed. On the one hand, the plasma wind can blow the material particles towards the powder outlet channel 13, thereby reducing the adsorption phenomenon and the accumulation phenomenon. On the other hand, the plasma wind can eliminate the static electricity on the material particles, thereby reducing the adsorption phenomenon and the powder flying phenomenon.

[0048] The specific structure of the above-mentioned grinding device 111 will be described below.

[0049] Refer to Figure 3 and Figure 4 , where Figure 4 is Figure 3 a partial enlarged view of the circular area in . In some embodiments of the present application, the plasma generator 15 is prominently arranged at the bottom of the grinding chamber 111. An avoidance opening 1411 is formed on each blade 141. When the blade 141 rotates, the blade 141 passes through the plasma generator 15 through the avoidance opening 1411.

[0050] In the embodiment of the present application, the plasma generator 15 can be fixed to the bottom of the grinding chamber 111 by screws or other fixing methods. Specifically, the generator body of the plasma generator 15 is fixed outside the grinding chamber 111, and the electrode end passes through the bottom of the grinding chamber 111 and extends into the grinding chamber 111 (that is, prominently arranged at the bottom of the grinding chamber 111) to release plasma inside the grinding chamber 111. At this time, in order to prevent the protruding electrode end from hindering the rotation of the blade 141, avoidance openings 1411 are formed at the corresponding positions of all the blades 141 in the embodiment of the present application, so that when the blade 141 rotates, the blade 141 can pass through the plasma generator 15 through the avoidance opening 1411 without being hindered.

[0051] In the embodiment of the present application, since the plasma generator 15 is prominently arranged at the bottom of the grinding chamber 111, the plasma generator 15 is closer to the impeller 14, and thus the plasma wind can be formed earlier, which can further improve the material adsorption phenomenon near the impeller 14.

[0052] Refer to Figure 5 and Figure 6 , where Figure 6 is Figure 5Partial enlarged view of the middle circular area. In some embodiments of the present application, the grinding bracket 11 is provided with a communication channel 112. One end of the communication channel 112 communicates with the grinding chamber 111, and the other end of the communication channel 112 communicates with the powder outlet channel 13. The plasma generator 15 is disposed in the communication channel 112.

[0053] In an embodiment of the present application, the grinding bracket 11 may be provided with a communication channel 112. One end of the communication channel 112 communicates with the grinding chamber 111, and the other end communicates with the powder outlet channel 13. The material particles can be pushed by the blades 141 and blown by the air flow, and are transported from the grinding chamber 111 to the communication channel 112, and then input from the communication channel 112 to the powder outlet channel 13. The plasma generator 15 may be disposed in the communication channel 112. When the material particles are transported to the communication channel 112, the plasma generator 15 disposed in the communication channel 112 can generate plasma to eliminate the static electricity on the material particles passing through the communication channel 112. Specifically, the electrode end of the plasma generator 15 can be fixed to the communication channel 112 on the grinding bracket 11 by screws or other fixing means. Furthermore, when the material particles ground by the grinding assembly 12 are scraped to the communication channel 112 by the impeller 14, the plasma released by the electrode end neutralizes the charges of the material particles, eliminating the static electricity between the material particles, thereby improving the situation where the material particles accumulate due to static electricity in the communication channel 112, reducing the residual powder retention in the communication channel 112, and at the same time improving the powder flying phenomenon caused by static electricity.

[0054] Reference Figure 5 And Figure 6 As shown in [relevant figure], in some embodiments of the present application, a plasma generator 15 is prominently disposed at the bottom of the grinding chamber 111. Each blade 141 is provided with an avoidance opening 1411. When the blade 141 rotates, the blade 141 passes through the plasma generator 15 through the avoidance opening 1411; the grinding bracket 11 is provided with a communication channel 112. One end of the communication channel 112 communicates with the grinding chamber 111, and the other end of the communication channel 112 communicates with the powder outlet channel 13. Another plasma generator 15 is disposed in the communication channel 112.

[0055] In an embodiment of the present application, in order to better eliminate the static electricity on the material particles, a plasma generator 15 can be respectively disposed at the bottom of the grinding chamber 111 and in the communication channel 112. The plasma emitted by the two plasma generators 15 can cover a larger range, thereby improving the static electricity elimination effect. The specific setting method can refer to the above embodiments and will not be elaborated here.

[0056] Reference Figure 7 As shown in [relevant figure], in some specific embodiments of the present application, another plasma generator 15 is disposed in the powder outlet channel 13.

[0057] In an embodiment of the present application, it can be understood that even if the static electricity of the material particles is eliminated when they reach the powder outlet channel 13, the material particles may still rub against the inner wall of the powder outlet channel 13 when passing through the powder outlet channel 13, resulting in the re-generation of static electricity. Therefore, in the embodiment of the present application, another plasma generator 15 is provided in the powder outlet channel 13, which can eliminate the static electricity on the material particles in the powder outlet channel 13, further improve the situation where the material particles accumulate in the powder outlet channel 13 due to static electricity, reduce the residual powder retention in the powder outlet channel 13, and at the same time improve the powder flying phenomenon caused by static electricity. Specifically, the electrode end can be fixed in the powder outlet channel 13 by screws or other fixing methods. Then, after being scraped by the impeller 14 to the communication channel 112 and then falling from the communication channel 112 into the powder outlet channel 13, the plasma released by the electrode end neutralizes the charges of the material particles, eliminating the static electricity between the material particles.

[0058] As Figure 8 shown, in some embodiments of the present application, the impeller 14 further includes a blade support 142, and the blades 141 are vertically arranged on the impeller 14.

[0059] In other embodiments of the present application, the impeller 14 further includes a blade support 142, and the blades 141 are inclinedly arranged on the impeller 14.

[0060] In an embodiment of the present application, the impeller 14 may include a blade support 142 and a plurality of blades 141 arranged on the periphery of the blade support 142, and the blades 141 may be vertically or inclinedly arranged on the impeller 14. When the impeller 14 rotates, it can drive all the blades 141 vertically or inclinedly arranged on the impeller 14 to generate an air flow and scrape the material particles.

[0061] Specifically, the impeller 14 can be installed on the support shaft of the grinding support 11 through the blade support 142, and the blades 141 can be arranged below the grinding assembly 12. The blade support 142 can be installed on the support shaft through a rotating shaft structure, so that the impeller 14 can rotate around the support shaft, thereby driving the blades 141 to rotate, and the blades 141 drive the powdery material to rotate, thereby conveying the powdery material.

[0062] In some embodiments of the present application, the bottom of the blade 141 contacts the bottom of the grinding chamber 111.

[0063] In other embodiments of the present application, the side surface of the blade 141 contacts the inside of the grinding chamber 111.

[0064] In an embodiment of the present application, when the impeller 14 rotates, the side surface of the blade 141 can contact the inner wall of the grinding chamber 111 to scrape the powder adhered to the inner wall of the grinding chamber 111. The bottom of the blade 141 can also contact the bottom of the grinding chamber 111 to scrape the powder adhered to the bottom of the grinding chamber 111, thereby reducing the adhesion of the material particles to the inside and the bottom of the grinding chamber 111.

[0065] As Figure 4 shown, in some embodiments of the present application, a positioning post 143 is provided at the top of the impeller 14, and a positioning hole 121 is provided at the bottom of the grinding assembly 12, and the positioning post 143 is inserted into the positioning hole 121.

[0066] In an embodiment of the present application, the impeller 14 is provided with a positioning post 143 at the top, and at the same time, the bottom of the grinding assembly 12 is provided with a positioning hole 121. Therefore, the positioning post 143 can be inserted into the positioning hole 121 to realize the relative fixation of the impeller 14 and the grinding assembly 12.

[0067] The above are only optional embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made under the practical concept of the present application by using the content of the specification and drawings of the present application, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present application.
