Description

Technical Field

[0001] This application relates to the field of grinding machine technology, and in particular to a grinding machine. Background Technology

[0002] Currently, in commercially available grinding machines, the material to be ground sometimes gets stuck at the bottom of the hopper and cannot fall into the grinding device connected to the hopper below. For example, in a tea grinder, when different varieties of tea are loaded into the hopper, especially when grinding leafy tea, the leafy tea can block the outlet of the tea hopper, preventing the tea from flowing into the grinding disc for grinding, resulting in slow grinding speed and unsatisfactory grinding effect.

[0003] In addition, the ground powder can easily clog the inlet of the powder outlet, preventing the tea powder from flowing out of the outlet properly. Since the ground tea powder cannot flow out completely, the residual powder will affect the taste and aroma of the tea when grinding different varieties of tea. Furthermore, the residual powder will turn black and turn brown after sitting for a long time, which can seriously affect a person's physical and mental health.

[0004] For example, Chinese utility model patent CN222074358U discloses a tea-grinding machine. The grinding chamber is divided into upper and lower chambers by a partition plate. Several soft bristles are installed on the grinding discs. The tea leaves are broken up by the counter-rotation of the two discs, facilitating later processing. An air box is installed in the center of the grinding chamber; intermittent gas filling the air box blows the broken tea leaves out of the grinding chamber. However, this blowing method easily spreads tea powder throughout the internal structure and crevices of the grinding machine, making cleaning difficult. Utility Model Content

[0005] The purpose of this application is to provide a grinding machine.

[0006] The embodiments of this application adopt the following technical solution: a grinding mill, characterized in that it includes a main unit assembly and a hopper assembly;

[0007] The hopper assembly contains the ingredients to be ground;

[0008] The main unit includes a housing, a powder outlet channel, a powder hopper, a motor, a cutter head assembly, and a cutting and feeding assembly;

[0009] The powder outlet channel is disposed on the housing, the powder hopper is disposed inside the housing, and the powder inlet of the powder outlet channel is connected to the powder hopper to receive the powder material in the powder hopper;

[0010] The lower end of the cutting and feeding assembly is connected to the output shaft of the motor, and the upper end of the cutting and feeding assembly extends from the bottom of the hopper assembly into the hopper assembly to cut the food in the hopper assembly and convey the cut food downward to the cutter head assembly located in the powder hopper.

[0011] The blade assembly is connected to the output shaft of the motor, and the blade assembly cuts and grinds the food ingredients after they have been cut by the cutting and feeding assembly;

[0012] A cleaning mechanism is used to clean the powder between the cutter head assembly and the powder hopper so that the powder can enter the powder outlet channel.

[0013] The cutting and feeding assembly can perform preliminary cutting of the tea leaves, allowing the pre-cut material to smoothly enter the grinding disc assembly for grinding. The cleaning mechanism can automatically and promptly remove powder stuck in the gap between the grinding disc assembly and the powder hopper, ensuring that the powder can smoothly enter the powder outlet channel and preventing powder accumulation in the gap between the grinding disc assembly and the powder hopper, as well as at the powder inlet of the powder outlet channel.

[0014] In some embodiments, the cutting and feeding assembly includes a screw and a stirring blade. The lower end of the screw is connected to the output shaft of the motor, and the upper end of the screw is connected to the stirring blade. The motor drives the stirring blade to rotate and cut the food in the hopper assembly. The screw conveys the cut food downward to the cutter head assembly for cutting and grinding. The stirring blade and the screw cooperate to allow the food in the hopper to be initially cut. The cut food, now smaller, can smoothly enter the cutter head assembly for grinding under the guidance of the rotating screw.

[0015] In some embodiments, the cleaning mechanism includes a pushing mechanism;

[0016] There is a gap between the outer peripheral surface of the blade assembly and the inner peripheral surface of the powder hopper. The pushing mechanism is disposed on the blade assembly and extends into the gap between the blade assembly and the powder hopper. The pushing mechanism moves synchronously with the blade assembly as the blade assembly rotates to grind the food, so as to push the powder located in the gap between the powder hopper and the blade assembly to the powder inlet of the powder outlet channel, thereby preventing the powder from accumulating in the gap between the blade assembly and the powder hopper.

[0017] In some embodiments, the pushing mechanism includes a pushing protrusion disposed on the cutter head assembly. The pushing protrusion extends from the outer periphery of the cutter head assembly toward the inner periphery of the powder hopper. The pushing protrusion has a simple structure and is easy to implement.

[0018] In some embodiments, the cleaning mechanism further includes a first cleaning component, which is disposed at the powder inlet of the powder hopper corresponding to the powder outlet channel to disperse the powder, thereby enabling the powder to enter the powder inlet of the powder outlet channel. The first cleaning component can disperse the powder accumulated at the powder outlet channel inlet to facilitate powder discharge.

[0019] In some embodiments, the first cleaning component includes a first cleaning member and a second cleaning member, the first cleaning member including a plurality of first baffles, and the second cleaning member including a plurality of second baffles;

[0020] One end of the plurality of first baffles is located on the first side of the powder inlet of the powder outlet channel, and the other end of the plurality of first baffles extends toward the second side of the powder inlet of the powder outlet channel, with the second side opposite to the first side;

[0021] One end of the plurality of second baffles is located on the second side of the powder inlet of the powder outlet channel, and the other end of the plurality of second baffles extends toward the first side of the powder inlet of the powder outlet channel. The plurality of first baffles and the plurality of second baffles are arranged in a staggered manner in the height direction of the powder inlet of the powder outlet channel.

[0022] The plurality of first baffles and second baffles are deformed at the powder inlet of the powder outlet channel by the compression of the powder and / or the discharge of the powder, so as to disperse the powder at the powder inlet of the powder outlet channel.

[0023] The staggered arrangement of the baffles makes them easy to deform, and when the baffles recover their deformation, they vibrate to break up the powder and prevent it from piling up into clumps that are difficult to discharge.

[0024] In some embodiments, the plurality of first baffles each have a first protrusion that protrudes toward the cutter head assembly;

[0025] Each of the plurality of second baffles has a second protrusion, which protrudes toward the cutter head assembly; wherein...

[0026] The second protrusion and the first protrusion are staggered in the height and width directions of the powder inlet of the powder outlet channel to form a space for powder to enter the powder inlet of the powder outlet channel. The structure of the baffles provides a gap between the first baffle and the second baffle, preventing powder from accumulating at the powder inlet of the powder outlet channel.

[0027] In some embodiments, the cleaning mechanism further includes a second cleaning component disposed at the powder inlet of the powder outlet channel. The second cleaning component has protruding cleaning ribs. When the powder enters the powder inlet of the powder outlet channel, it pushes the cleaning ribs to deform into the powder inlet of the powder outlet channel. When the cleaning ribs return to their original shape, they disperse the powder, thereby allowing the powder to enter the powder inlet of the powder outlet channel and preventing powder accumulation at the edge of the powder outlet channel.

[0028] In some embodiments, the second cleaning component further includes a cleaning body, and the cleaning ribs include a plurality of cleaning ribs, which are arranged vertically at intervals along the cleaning body, and the plurality of cleaning ribs extend into the gaps between the plurality of vertically arranged first baffles or second baffles to clean the powder in the gaps between the plurality of first baffles or second baffles.

[0029] The cleaning body has a deformation notch in the middle, which divides the cleaning body into two parts with an upper and lower gap. The cleaning rib is set in the lower part of the separated cleaning body. The lower part of the separated cleaning body has a deformation groove on the side close to the inner wall of the powder chamber, so that when the cleaning rib is deformed by force, the lower part of the cleaning body can deform towards the deformation groove.

[0030] In some embodiments, the cutter head assembly includes an upper cutter head, a lower cutter head, and a lower cutter holder. The upper cutter head is fixed inside the powder hopper, the lower cutter head is disposed on the lower cutter holder, and the lower cutter head is located below the upper cutter head. The lower cutter holder is connected to the output shaft of the motor and rotates relative to the upper cutter head under the drive of the motor.

[0031] The top of the lower tool holder extends upward from the center of the lower tool disc and the upper tool disc;

[0032] The grinding mill also includes a height adjustment component connected to the lower cutter holder and used to adjust the gap between the lower cutter disc and the upper cutter disc in the height direction of the grinding mill. The height adjustment component allows adjustment of the gap between the upper and lower cutter discs in the height direction of the grinding mill to grind powders of different fineness.

[0033] In some embodiments, the height adjustment assembly includes a knob shaft, a knob seat, a lifting seat, a pressure seat, and a spring;

[0034] One end of the knob shaft is located outside the housing, and the other end of the knob shaft has a first bevel gear;

[0035] The knob seat is sleeved on the output shaft of the motor and does not rotate with the output shaft of the motor. The knob seat has a base and a protrusion protruding upward from the base. The base has a second bevel gear that meshes with the first bevel gear. The protrusion is provided with an external thread.

[0036] The lifting seat has an internal thread, the top of the lifting seat contacts the bottom surface of the lower tool holder, the internal thread engages with the external thread of the knob seat, when the knob shaft rotates, the knob seat is driven to rotate through the engagement of the first bevel gear and the second bevel gear, thereby driving the lifting seat to rise and fall, so as to push the lower tool holder and the lower tool disc to rise and fall;

[0037] The pressure seat is located at the top of the motor's rotating shaft, and the spring is located inside the pressure seat, with the bottom of the spring abutting against the top surface of the lower cutter holder. The gap between the upper and lower cutter discs in the height direction of the grinding machine can be adjusted by rotating the knob shaft, making operation simple. Attached Figure Description

[0063] Specific embodiments of this application are described thereafter with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of this application, which can be implemented in various ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that could obscure the application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in a variety of substantially any suitable detailed structures.

[0064] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0065] This application provides a grinder that can be used to grind food ingredients, such as tea leaves 2.7, beans, seasonings, herbs, etc. The following explanation uses tea leaves 2.7 as an example.

[0066] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the grinding machine includes a main unit assembly 1 and a hopper assembly.

[0067] The hopper assembly contains the material to be ground. For example, the hopper assembly contains tea leaves 2.7 to be ground. The hopper assembly may include a hopper body 2.1, a top cover 2.2, a hopper mounting base 2.5, a rotating shaft 2.6, and a baffle.

[0068] Combination Figure 5The hopper mounting base 2.5 can be located on top of the main unit 1. Both the top and bottom of the hopper mounting base 2.5 have openings, and the hopper mounting base 2.5 can be flared with a large opening at the top. The top and bottom of the hopper body 2.1 also have openings, and the bottom of the hopper body 2.1 can extend into the hopper mounting base 2.5 through the top opening. The bottom shape of the hopper body 2.1 is adapted to at least a portion of the shape of the hopper mounting base 2.5, so that the hopper body 2.1 can be detachably mounted within the hopper mounting base 2.5.

[0069] The hopper body 2.1 is equipped with a baffle that can divide the hopper body 2.1 into upper and lower storage spaces. For example, a rotating shaft 2.6 is provided on the hopper body 2.1, and the baffle can rotate around the rotating shaft 2.6. When the baffle rotates into the hopper body 2.1 around the rotating shaft 2.6, it can divide the hopper body 2.1 into upper and lower storage spaces. When the baffle rotates out of the hopper body 2.1 around the rotating shaft 2.6, it can connect the two separated storage spaces.

[0070] When adding tea leaves 2.7 into the hopper body 2.1, the baffle 2.4 can be moved around the rotating shaft 2.6 to displace the hopper body 2.1. The top cover 2.2 can then be opened, and the tea leaves 2.7 can be poured into the hopper body 2.1. If the baffle is not open, it can be opened by rotating it around the center of the rotating shaft 2.6, allowing the tea leaves 2.7 to automatically fall to the bottom of the hopper body 2.1. If the tea leaves 2.7 in the hopper body 2.1 are not yet used up, but a different type of tea leaves 2.7 needs to be ground, the baffle can be rotated around the center of the rotating shaft 2.6 into the hopper body 2.1. The top cover 2.2 can then be opened, and the tea leaves 2.7 removed from the hopper body 2.1 can be replaced with new tea leaves 2.7.

[0071] The top cover 2.2 can be fastened to the open position on the top of the hopper body 2.1 to prevent impurities and other foreign objects from entering the hopper body 2.1.

[0072] A safety cover 2.3 can also be installed inside the hopper body 2.1. For example, the safety cover 2.3 can prevent hands from being put into the hopper body 2.1 and causing harm.

[0073] The main unit 1 includes a housing, a powder outlet channel 1.23, a powder hopper 1.10, a motor 1.6, a cutter head assembly, and a cutting and feeding assembly.

[0074] The powder outlet channel 1.23 is disposed on the housing, and the powder hopper 1.10 is disposed inside the housing. The powder inlet of the powder outlet channel 1.23 is connected to the powder hopper 1.10 to receive the powder material in the powder hopper 1.10.

[0075] One end of the powder outlet channel 1.23 is connected to the powder hopper 1.10, and the other end of the powder outlet channel 1.23 is located outside the housing. The ground tea powder 1.25 in the powder hopper 1.10 enters the powder outlet channel 1.23 through the powder inlet. The powder outlet channel 1.23 can be arranged at an angle so that the tea powder 1.25 can be discharged along the inclined powder outlet channel 1.23.

[0076] The lower end of the cutting and feeding assembly is connected to the output shaft of the motor 1.6, and the upper end of the cutting and feeding assembly extends from the bottom of the hopper assembly into the hopper assembly to cut the ingredients in the hopper assembly and convey the cut ingredients downward to the cutter head assembly located in the powder hopper 1.10. For example, the upper end of the cutting and feeding assembly can extend to the lower half of the hopper body 2.1, and the top of the cutting and feeding assembly does not exceed the baffle. The rotation of the motor 1.6 drives the cutting and feeding assembly to rotate, thereby performing preliminary cutting on the tea leaves 2.7 in the hopper body 2.1 (especially the lower part of the hopper body 2.1). The preliminarily cut tea leaves 2.7 become smaller and fall naturally downward. Then, the tea leaves 2.7 in the upper part of the hopper body 2.1 will continuously move downward, solving the problem of tea leaves 2.7 accumulating in the lower part of the hopper body 2.1. The preliminarily cut tea leaves 2.7 will enter the top-open cutter head assembly under the guiding action of the cutting and feeding assembly.

[0077] The blade assembly is connected to the output shaft of the motor 1.6, and the blade assembly cuts and grinds the food ingredients after they have been cut by the cutting and feeding assembly. In addition to driving the cutting and feeding assembly to rotate, the motor 1.6 can also drive the blade assembly to rotate. The blade assembly rotates to cut and grind the tea leaves 2.7 that have entered the blade assembly, so as to grind the tea leaves 2.7 into tea powder 1.25.

[0078] The cutter head assembly includes an upper cutter head 1.14, a lower cutter head 1.13, and a lower cutter holder 1.9. The upper cutter head 1.14 is fixed inside the powder hopper 1.10. The lower cutter head 1.13 is disposed on the lower cutter holder 1.9 and is located below the upper cutter head 1.14. The lower cutter holder 1.9 is connected to the output shaft of the motor 1.6 and rotates relative to the upper cutter head 1.14 under the drive of the motor 1.6.

[0079] For example, the upper cutter disc 1.14 can be fixed on the upper cutter holder 1.3, which is fixed on the hopper. The upper cutter holder 1.3 has openings at both its top and bottom, and the lower part of the hopper mounting base 2.5 extends into the opening at the top of the upper cutter holder 1.3. The bottom surface of the upper cutter disc 1.14 has a grinding surface, which can be equipped with grinding grooves or other grinding structures for grinding tea leaves 2.7. The lower cutter disc 1.13 is mounted on the lower cutter holder 1.9, which rotates under the drive of the motor 1.6, thereby causing the lower cutter disc 1.13 to rotate. The top surface of the lower cutter disc 1.13 has a grinding surface opposite to the grinding surface of the upper cutter disc 1.14, and the grinding surface of the lower cutter disc 1.13 also has grinding grooves or other structures for grinding tea leaves 2.7. The upper blade 1.14 and the lower blade 1.13 have a certain gap in the height direction of the grinder. The lower blade 1.13 rotates relative to the upper blade 1.14 to grind the tea leaves 2.7 that enter the gap between the upper blade 1.14 and the lower blade 1.13.

[0080] The housing is equipped with a control board assembly 1.22. During grinding, the power is plugged in and the relevant working mode of the control board assembly 1.22 is activated, causing the motor 1.6, the lower blade 1.13, the screw 1.17, and the stirring blade 1.19 to rotate simultaneously. At this time, the stirring blade 1.19 first crushes the tea leaves 2.7, making it easier for the tea leaves 2.7 to fall into the bottom position of the hopper body 2.1. Then, the screw 1.17 can evenly push the crushed tea leaves 2.7 into the blade assembly for grinding.

[0081] The cleaning mechanism of the grinder is used to clean the powder between the cutter head assembly and the powder hopper 1.10, so that the powder can enter the powder outlet channel 1.23. Here, the powder between the cutter head assembly and the powder hopper 1.10 also includes the powder at the powder inlet of the powder outlet channel 1.23. The cleaning mechanism cleans the tea powder 1.25 while grinding the tea leaves 2.7. Of course, when there are no tea leaves 2.7 to be ground in the hopper body 2.1, or when changing the tea leaves 2.7 to be ground, the grinder can continue grinding so that the cleaning mechanism can continuously clean the ground tea powder 1.25 until no tea powder 1.25 flows out of the powder outlet channel 1.23, thus achieving a thorough cleaning of the grinder.

[0082] The cutting and feeding assembly of this embodiment can perform preliminary cutting on the tea leaves 2.7, so that the pre-cut ingredients can smoothly enter the blade assembly for grinding. The cleaning mechanism can automatically and promptly clean up the powder stuck in the gap between the blade assembly and the powder hopper 1.10, so that the powder can smoothly enter the powder outlet channel 1.23, avoiding the accumulation of powder in the gap between the blade assembly and the powder hopper 1.10 and at the powder inlet of the powder outlet channel 1.23.

[0083] In some embodiments, the cutting and feeding assembly includes a screw 1.17 and a stirring blade 1.19. The lower end of the screw 1.17 is connected to the output shaft of the motor 1.6, and the upper end of the screw 1.17 is connected to the stirring blade 1.19. The motor 1.6 drives the stirring blade 1.19 to rotate and cut the food in the hopper assembly. The screw 1.17 conveys the cut food downwards to the cutter head assembly for further cutting and grinding. The stirring blade 1.19 cooperates with the screw 1.17 to allow the food in the hopper to be initially cut. The smaller pieces of food can then smoothly enter the cutter head assembly for grinding under the guidance of the rotating screw 1.17.

[0084] For example, the screw 1.17 has a guide thread arranged axially. The screw 1.17 and the stirring blade 1.19 at the top of the screw 1.17 can rotate under the drive of the motor 1.6. The stirring blade 1.19 can have cutting blades. The rotation of the blades of the stirring blade 1.19 can perform preliminary cutting of the tea leaves 2.7 in the lower half of the hopper body 2.1, so as to preliminarily cut the tea leaves 2.7 into smaller sizes, thus solving the problem of the tea leaves 2.7 accumulating crosswise at the bottom of the hopper body 2.1. The preliminarily cut tea leaves 2.7 fall downwards and are continuously conveyed into the cutter head assembly under the action of the guide thread of the screw 1.17, improving the efficiency of tea leaf 2.7 feeding into the hopper assembly.

[0085] In some embodiments, combined with Figure 6 , Figure 7 , Figure 8 and Figure 9 The cleaning mechanism includes a pushing mechanism, which pushes the powder in the gap between the main cutter head assembly and the powder hopper 1.10 to the air inlet of the powder outlet channel.

[0086] A gap exists between the outer circumferential surface of the blade assembly and the inner circumferential surface of the powder hopper 1.10, allowing the tea powder 1.25 ground by the blade assembly to fall into this gap. A pushing mechanism is mounted on the blade assembly and extends into the gap between the blade assembly and the powder hopper 1.10. This pushing mechanism operates synchronously with the blade assembly as it rotates and grinds the tea, pushing the powder located in the gap between the powder hopper 1.10 and the blade assembly to the powder inlet of the powder outlet channel 1.23, thus preventing powder accumulation in the gap between the blade assembly and the powder hopper 1.10.

[0087] For example, the feeding mechanism includes a feeding protrusion 1.9.1, which is disposed on the cutter disc assembly. Specifically, the feeding protrusion 1.9.1 can be disposed on the outer peripheral surface of the lower cutter holder 1.9 and rotate together with the lower cutter holder 1.9 and the lower cutter disc 1.13. One or more feeding protrusions 1.9.1 can be disposed along the outer peripheral surface of the lower cutter holder 1.9. Preferably, multiple feeding protrusions 1.9.1 can be disposed along the outer peripheral surface of the lower cutter holder 1.9. Each feeding protrusion 1.9.1 is spaced at a certain angle so that the tea powder 1.25 in the gap between the cutter disc assembly and the powder hopper 1.10 can be pushed by the cooperation of multiple feeding protrusions 1.9.1. The amount of tea powder 1.25 between two adjacent feeding protrusions 1.9.1 is relatively small, avoiding excessive tea powder 1.25 being pushed by the same feeding protrusion 1.9.1 and accumulating into lumps in the gap between the cutter disc assembly and the powder hopper 1.10.

[0088] The pusher protrusion 1.9.1 extends from the outer periphery of the lower cutter holder 1.9 towards the inner periphery of the powder hopper 1.10. The pusher protrusion 1.9.1 can be made of metal or a material with a certain deformation capacity. The pusher protrusion 1.9.1 has a simple structure and is easy to implement.

[0089] In some embodiments, combined with Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The cleaning mechanism further includes a first cleaning component, which is disposed at the powder inlet of the powder hopper 1.10 corresponding to the powder outlet channel 1.23. The first cleaning component mainly disperses the powder at the powder inlet, so that the powder can enter the powder outlet channel 1.23 for easy powder discharge.

[0090] For example, the first cleaning component includes a first cleaning element 1.20 and a second cleaning element 1.21, which are respectively fixed at the powder inlet of the powder outlet channel 1.23. Figure 11 and Figure 12 The first cleaning component 1.20 includes a plurality of first baffles 1.20.1, and the second cleaning component 1.21 includes a plurality of second baffles 1.21.1.

[0091] Wherein, one end of the plurality of first baffles 1.20.1 is located on the first side of the powder inlet of the powder outlet channel 1.23, and the other end of the plurality of first baffles 1.20.1 extends toward the second side of the powder inlet of the powder outlet channel 1.23, the second side being opposite to the first side.

[0092] For example, the first cleaning component 1.20 also includes a first substrate with an opening. The first substrate can be fixed to the powder inlet with screws, and the opening of the first substrate is not smaller than the size of the powder inlet. Multiple first baffles 1.20.1 each have a free end, extending from the first substrate towards the opening of the first substrate, and the free end can be bent and extended into the powder outlet channel 1.23. When extending, the first baffles 1.20.1 can also extend into the opening of the first substrate, first towards the blade assembly, and then into the powder outlet channel 1.23, with the free end of the first baffle 1.20.1 located within the powder outlet channel 1.23. That is, each of the multiple first baffles 1.20.1 has a first protrusion, which can be located at the center of the first baffle 1.20.1.

[0093] Similarly, one end of the plurality of second baffles 1.21.1 is located on the second side of the powder inlet of the powder outlet channel 1.23, and the other end of the plurality of second baffles 1.21.1 extends toward the first side of the powder inlet of the powder outlet channel 1.23. The plurality of first baffles 1.20.1 and the plurality of second baffles 1.21.1 are arranged in a staggered manner in the height direction of the powder inlet of the powder outlet channel 1.23.

[0094] The second cleaning component 1.21 also includes a second substrate with an opening, which may be the same as the opening on the first substrate. The second substrate can be stacked with the first substrate and then fixed to the powder inlet with screws. Unlike the first cleaning component 1.20, the multiple second baffles 1.21.1 are arranged in opposite directions, and the second baffles 1.21.1 and the first baffles 1.20.1 are staggered vertically along the height direction of the powder inlet of the powder outlet channel 1.23 (which is also the height direction of the grinder).

[0095] That is, the overall structure of the second cleaning component 1.21 is similar to that of the first substrate. Multiple second baffles 1.21.1 each have a second protrusion that protrudes towards the cutter head assembly. The second protrusions and the first protrusions are staggered in both the height and width directions of the powder inlet of the powder outlet channel 1.23, meaning the first and second protrusions can be located on different straight lines to form a space for powder to enter the powder inlet of the powder outlet channel 1.23. This baffle structure ensures a certain gap between the first baffle 1.20.1 and the second baffle 1.21.1, preventing powder from accumulating at the powder inlet of the powder outlet channel 1.23.

[0096] Multiple first baffles 1.20.1 and second baffles 1.21.1 are deformed at the powder inlet of the powder outlet channel 1.23 by the compression of powder and / or the discharge of powder, so as to disperse the powder at the powder inlet of the powder outlet channel 1.23.

[0097] Both the first baffle 1.20.1 and the second baffle 1.21.1 are sheet-like structures with elastic deformation capabilities. As tea powder 1.25 is continuously pushed to the powder inlet, the first baffle 1.20.1 and the second baffle 1.21.1 are pushed into the powder outlet channel 1.23 by the powder and deformed. When there is no tea powder 1.25 outside the powder inlet of the powder outlet channel 1.23, the first baffle 1.20.1 and the second baffle 1.21.1 will return to their original shape. During this process, the first baffle 1.20.1 and the second baffle 1.21.1 will vibrate. Under the action of vibration, the tea powder 1.25 at the air inlet of the powder outlet channel 1.23 (including the tea powder that has already entered the powder outlet channel 1.23) is dispersed, preventing the tea powder 1.25 from clumping and thus preventing it from being discharged smoothly from the powder outlet channel 1.23.

[0098] The first baffle 1.20.1 and the second baffle 1.21.1, which are arranged in a cross-staggered manner, are easy to deform and vibrate when the first baffle 1.20.1 and the second baffle 1.21.1 recover their deformation, so as to break up the powder and prevent the powder from accumulating into lumps that are difficult to discharge.

[0099] In some embodiments, the cleaning mechanism further includes a second cleaning component disposed at the powder inlet of the powder outlet channel 1.23, the second cleaning component having a protruding cleaning rib 1.24.1. For example, the second cleaning component may be disposed on the powder hopper 1.10, with the cleaning rib 1.24.1 located at the powder inlet. Figure 10 The cleaning ribs 1.24.1 may include multiple cleaning ribs 1.24.1, which may be arranged vertically at intervals along the cleaning body 1.24, and the multiple cleaning ribs 1.24.1 respectively extend into the gaps between the multiple vertically arranged first baffles 1.20.1 or multiple second baffles 1.21.1. Figure 10 The diagram shows each cleaning rib 1.24.1 extending into the gap between multiple vertically arranged first baffles 1.20.1. That is, a cleaning rib 1.24.1 can be positioned between every two adjacent first baffles 1.20.1, capable of cleaning tea powder from the gaps between multiple first baffles 1.20.1 or multiple second baffles 1.21.1. Combined with... Figure 6 , Figure 7 , Figure 8 and Figure 9 The cleaning mechanism 1.24.1 has a certain deformation capability. The lower cutter disc 1.13 rotates clockwise, and the second cleaning component is set on the side of the powder hopper 1.10 corresponding to the side of the pusher mechanism that is about to rotate to the air inlet. Powder accumulation is prone to occur at this position.

[0100] Combination Figure 13The second cleaning component includes a cleaning body 1.24. A hanging groove 1.24.2 can be provided on the top of the cleaning body 1.24, which is snapped into the top edge of the powder hopper 1.10. The cleaning body 1.24 is elongated and extends downwards along the inner circumference of the powder hopper 1.10. Multiple cleaning ribs 1.24.1 can be provided along the length of the cleaning body 1.24, each cleaning rib 1.24.1 protruding into the gap between the cutter head assembly and the powder hopper 1.10.

[0101] Combination Figure 14 and Figure 15 The cleaning body 1.24 has a deformation notch 1.24.3 in the middle, which divides it into upper and lower sections. The lower section of the cleaning body 1.24 is used to house the cleaning ribs 1.24.1, and a deformation groove 1.24.4 is provided behind the cleaning ribs 1.24.1. This allows the lower section of the cleaning body 1.24 to deform towards the deformation groove 1.24.4 when the cleaning ribs 1.24.1 are subjected to force, thus improving the cleaning capability of the second cleaning component.

[0102] Under the pushing action of the feeding mechanism, the powder can enter the powder inlet of the powder outlet channel 1.23. The powder will push the cleaning rib 1.24.1 to deform towards the inside of the powder outlet channel 1.23. When the cleaning rib 1.24.1 returns to its deformed state, it will disperse the powder, thereby allowing the powder to enter the powder outlet channel 1.23 and avoiding the accumulation of powder at the edge of the powder outlet channel 1.23. In addition, when the pushing mechanism rotates to the position of the cleaning rib 1.24.1, it will also push the cleaning rib 1.24.1, causing the cleaning rib 1.24.1 to deform inward towards the powder outlet channel 1.23. As the pushing mechanism continues to rotate with the cutter head assembly until the force on the cleaning rib 1.24.1 is released, the cleaning rib 1.24.1 will recover its deformation. At this time, the deformation is greater than the deformation when the powder exerts force on the cleaning rib 1.24.1. The tea powder 1.25 will be dispersed under the vibration of the cleaning rib 1.24.1 recovering its deformation.

[0103] In some embodiments, the grinder further includes a height adjustment component connected to the lower cutter holder 1.9 and used to adjust the gap between the lower cutter disc 1.13 and the upper cutter disc 1.14 in the height direction of the grinder. The height adjustment component allows adjustment of the gap between the upper cutter disc 1.14 and the lower cutter disc 1.13 in the height direction of the grinder to grind powders of different fineness.

[0104] The height adjustment assembly includes a knob shaft 1.12, a knob seat 1.7, a lifting seat 1.8, a pressure seat 1.15, and a spring 1.16.

[0105] One end of the knob shaft 1.12 is located outside the housing, and the other end of the knob shaft 1.12 has a first bevel gear. The end of the knob shaft 1.12 located outside the housing can be used to adjust the gap between the upper cutter head 1.14 and the lower cutter head 1.13 in the height direction of the grinding machine, so that the operator can clearly know the current gap between the upper cutter head 1.14 and the lower cutter head 1.13.

[0106] The knob seat 1.7 is fitted onto the output shaft of the motor 1.6 and does not rotate with the output shaft of the motor 1.6. The knob seat 1.7 will rotate under the driving action of the knob shaft 1.12.

[0107] The knob seat 1.7 has a base and a protrusion extending upward from the base. The base has a second bevel gear that meshes with the first bevel gear, and the protrusion is provided with an external thread.

[0108] The lifting seat 1.8 has an internal thread. The top of the lifting seat 1.8 contacts the bottom surface of the lower tool holder 1.9. The internal thread engages with the external thread of the knob seat 1.7. When the knob shaft 1.12 rotates, the knob seat 1.7 is driven to rotate through the engagement of the first bevel gear and the second bevel gear, thereby driving the lifting seat 1.8 to rise and fall, so as to push the lower tool holder 1.9 and the lower tool disc 1.13 to rise and fall, thereby achieving the size of the gap between the lower tool disc 1.13 and the upper tool disc 1.14.

[0109] The pressure seat 1.15 is located on top of the rotating shaft 2.6 of the motor 1.6. The bottom of the pressure seat 1.15 can have a receiving space for accommodating the spring 1.16. Specifically, the spring 1.16 is located inside the pressure seat 1.15, and its top end can abut against the inner top surface of the pressure seat 1.15. The top of the lower cutter holder 1.9 can extend upwards from the center of the lower cutter disc 1.13 and the upper cutter disc 1.14, and the bottom end of the spring 1.16 abuts against the top surface of the lower cutter holder 1.9. During the raising and lowering of the lower cutter holder 1.9, the bottom end of the spring 1.16 maintains constant contact with the lower cutter holder 1.9 to ensure a stable gap between the lower cutter disc 1.13 and the upper cutter disc 1.14, preventing changes in the height of the lower cutter disc 1.13 and the lower cutter holder 1.9 in the grinding machine. The gap between the upper cutter head 1.14 and the lower cutter head 1.13 in the height direction of the grinding machine can be adjusted by rotating the knob shaft 1.12, which is simple to operate.

[0110] The foregoing has described in detail several embodiments of this application, but this application is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications based on the concept of this application, and all such variations and modifications should fall within the scope of protection claimed in this application.
