Description

Technical Field

[0001] This utility model relates to the field of coffee processing technology, specifically to a coffee grinding device that facilitates control of the amount of feed added. Background Technology

[0002] A coffee grinder is a device that grinds coffee beans into coffee powder. Its core function is to adjust the grind size (coarseness) to suit different extraction methods (such as pour-over, espresso, etc.), thereby affecting the flavor and taste of the coffee. Existing coffee grinders usually do not have a precise grind size adjustment device, or the adjustment range is limited, making it difficult to meet the strict requirements of different coffee brewing methods for the coarseness of the coffee powder.

[0003] A search revealed a utility model patent with publication number CN222398080U, which discloses a coffee grinding device. The device includes a housing, a rotating shaft, and a drive motor. A female grinding head is housed within an opening at the bottom of the housing. The rotating shaft is coaxially and rotatably mounted within the housing, with a female grinding head adapted to the female grinding head at its lower end. The distance between the female and female grinding heads is adjustable. The drive motor drives the rotating shaft to rotate. A first thread is circumferentially arranged around the upper end of the rotating shaft, and a ring-shaped worm gear is rotatably connected to the housing. This application overcomes the limitations of traditional coffee grinding devices. The finer the coffee beans are ground, the larger the contact area with water, resulting in a more bitter taste; conversely, coarser grinding reduces the contact area with water, reducing bitterness. Furthermore, the current device cannot adjust the degree of grinding, making it unsuitable for diverse preferences. Therefore, this invention provides a coffee grinding device that can adjust the degree of grinding to cater to a wider range of preferences.

[0004] The aforementioned patent only uses a motor to drive the grinding head, and the grinding of coffee to different degrees can be achieved by adjusting the distance between the two grinding heads. However, this device cannot control the amount of coffee ground each time, which may cause fluctuations in the amount of coffee ground each time, resulting in differences in coffee flavor. It is not convenient to unify the coffee flavor. At the same time, controlling the amount of coffee ground reduces the waste of coffee beans.

[0005] Therefore, it is necessary to invent a coffee grinding device that makes it easy to control the amount of ingredients added to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a coffee grinding device that facilitates control over the amount of coffee beans fed. It achieves adjustable grinding of coffee beans through a motor, grinding hopper, and grinding disc, and controls the amount of coffee beans ground through a storage hopper, discharge port, opening, and electric push rod, thereby solving the problem of differences in coffee flavor caused by differences in the amount of coffee beans fed in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a coffee grinding device for easy control of the amount of feed, comprising a protective shell, a discharge barrel fixedly connected through the inside of the protective shell, a storage barrel fixedly connected to the upper end of the discharge barrel, the storage barrel communicating with the inside of the discharge barrel, a barrel lid fixedly connected to the upper end of the storage barrel via a hinge, a feeding pipe fixedly connected to the lower end of the discharge barrel, a grinding barrel fixedly connected through the side wall of the feeding pipe, the feeding pipe communicating with the inside of the grinding barrel, a motor fixedly connected to the inner wall of the protective shell, a rotating shaft fixedly connected to the output end of the motor via a coupling, the rotating shaft rotatably connected through the inside of the grinding barrel, a first grinding disc and a third grinding disc fixedly connected to the side wall of the rotating shaft, and a second grinding disc and a fourth grinding disc fixedly connected to the inner wall of the grinding barrel.

[0008] Preferably, two electric actuators are fixedly connected to the side wall of the discharge hopper, and the output ends of the two electric actuators are fixedly connected to an opening, and the side wall of the opening is slidably connected to the side wall of the discharge hopper.

[0009] Preferably, the grinding barrel is fixedly connected to a discharge port at its end, the discharge port is fixedly connected to the inside of the protective shell, the protective shell is fixedly connected to a cup holder on its side wall, the discharge port side wall is fixedly connected to two electric push rods, the output ends of the two electric push rods are fixedly connected to openings, and the side wall of the openings is slidably connected to the discharge port side wall.

[0010] Preferably, a fan is fixedly connected inside the protective shell, a connecting pipe is fixedly connected to the output end of the fan, an annular pipe is fixedly connected through the end of the connecting pipe, and multiple high-pressure nozzles are fixedly connected through the annular pipe, which is then fixedly connected inside the grinding barrel.

[0011] Preferably, a filter box is fixedly connected to the input end of the fan, a filter plate is slidably connected inside the filter box, and a filter cotton core is detachably connected to the inner wall of the filter plate.

[0012] Preferably, a bracket is fixedly connected to the inner wall of the storage bin, a rotating motor is fixedly connected through the bracket, and a screw is fixedly connected to the output end of the rotating motor via a coupling.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] Weighing sensors are installed at the top of the two openings. When it is necessary to control the amount of raw materials fed, the device automatically drives the two electric push rods when the weight of the coffee beans at the top of the opening decreases by a certain amount. The two electric push rods extend and cause the two openings to slide relative to each other, so that the openings close and the coffee beans entering the grinding barrel are controlled.

[0015] Once grinding is complete, start the blower. The blower input draws in air and pumps it into the connecting pipe. The air is then ejected through the connecting pipe into the annular pipe, then into multiple high-pressure nozzles, and finally ejected through the high-pressure nozzles to create a high-pressure pulse jet inside the grinding barrel, reducing coffee powder residue inside the grinding barrel.

[0027] This utility model provides, for example Figure 1-5 The coffee grinding device shown is designed for easy control of feed amount. It includes a protective housing 001, with a discharge hopper 101 fixedly connected inside the housing 001. A storage hopper 102 is fixedly connected to the upper end of the discharge hopper 101, communicating with the interior of the discharge hopper 101. A lid 103 is fixedly connected to the upper end of the storage hopper 102 via a hinge. A feed pipe 104 is fixedly connected to the lower end of the discharge hopper 101, with a grinding hopper 201 fixedly connected to its side wall, communicating with the interior of the grinding hopper 201. A motor 202 is fixedly connected to the inner wall of the protective housing 001, and a rotating shaft 203 is fixedly connected to the output end of the motor 202 via a coupling. The rotating shaft 203 is rotatably connected to the grinding hopper 201. Inside, grinding disc 1 204 and grinding disc 3 206 are fixedly connected to the side wall of the rotating shaft 203. Grinding disc 2 205 and grinding disc 4 207 are fixedly connected to the inner wall of the grinding barrel 201. When the barrel lid 103 is opened, the coffee beans to be ground are poured into the storage barrel 102. The coffee beans enter the feeding pipe 104 through the storage barrel 102 and the discharge barrel 101, and then enter the grinding barrel 201 through the feeding pipe 104. The inner wall of the grinding barrel 201 is provided with a grinding groove. The drive motor 202 is a servo motor with the model number SGM7G-55A6C6E. The output end of the motor 202 rotates, which drives the rotating shaft 203 to rotate. The rotation of the rotating shaft 203 drives the grinding disc 1 204 and grinding disc 3 206 to rotate, and together with the grinding disc 2 205 and grinding disc 4 207, they grind the coffee beans.

[0028] Two electric push rods 105 are fixedly connected to the side wall of the discharge hopper 101. Openings 106 are fixedly connected to the output ends of the two electric push rods 105. The side wall of the opening 106 is slidably connected to the side wall of the discharge hopper 101. When grinding stops, the two electric push rods 105 are driven to extend, causing the two openings 106 to slide relative to each other, thus closing the openings 106 and stopping coffee beans from entering the grinding hopper 201. Weighing sensors are installed at the upper ends of the two openings 106. When it is necessary to control the amount of raw material added, the device automatically drives the two electric push rods 105 to extend, causing the two openings 106 to slide relative to each other, thus closing the openings 106 and controlling the amount of coffee beans entering the grinding hopper 201.

[0029] A discharge port 302 is fixedly connected to the end of the grinding barrel 201. The discharge port 302 is fixedly connected to the inside of the protective shell 001. A cup holder 301 is fixedly connected to the side wall of the protective shell 001. Two electric actuators 303 are fixedly connected to the side wall of the discharge port 302. An opening 304 is fixedly connected to the output end of the two electric actuators 303. The side wall of the opening 304 is slidably connected to the side wall of the discharge port 302. When the powder receiving cup is placed in the groove at the upper end of the cup holder 301, the two electric actuators 304 are driven. 3. The two electric push rods 303 retract, causing the two openings 304 to separate relative to each other, so that the openings 304 open and the coffee powder can fall from the outlet 302 into the powder receiving cup. A weighing sensor is installed at the upper end of the cup holder 301. When the weight in the powder receiving cup exceeds the set value, the device automatically drives the two electric push rods 303 to extend, causing the two openings 304 to slide relative to each other, so that the openings 304 close, thus controlling the coffee powder that has been ground and discharged.

[0030] A fan 401 is fixedly connected inside the protective shell 001. A connecting pipe 402 is fixedly connected to the output end of the fan 401. An annular pipe 403 is fixedly connected through the end of the connecting pipe 402. Multiple high-pressure nozzles 404 are fixedly connected through the annular pipe 403. The multiple high-pressure nozzles 404 are fixedly connected through the inside of the grinding barrel 201. When grinding is completed, the fan 401 is started. The input end of the fan 401 draws in air and pumps it into the connecting pipe 402. The air is then sprayed out through the connecting pipe 402 and into the annular pipe 403. It then enters the multiple high-pressure nozzles 404 through the annular pipe 403 and is finally sprayed out through the high-pressure nozzles 404 to perform high-pressure pulse jet spraying inside the grinding barrel 201, reducing the residue of coffee powder inside the grinding barrel 201.

[0031] A filter box 405 is fixedly connected to the input end of the fan 401. A filter plate 406 is slidably connected inside the filter box 405. A filter cotton core 407 is detachably connected to the inner wall of the filter plate 406. When the fan 401 is sucking, the air enters the fan 401 after being filtered by the filter plate 406 and the filter cotton core 407 inside the dustproof filter box 405, preventing impurities in the air from entering the grinding barrel 201 and contaminating the inside of the grinding barrel 201.

[0032] A bracket 501 is fixedly connected to the inner wall of the storage hopper 102. A rotating motor 502 is fixedly connected through the inside of the bracket 501. A screw 503 is fixedly connected to the output end of the rotating motor 502 through a coupling. The rotation of the rotating motor 502 drives the screw 503 to rotate. The rotation of the screw 503 drives the coffee beans to be conveyed downward at a uniform speed, preventing the coffee beans inside the storage hopper 102 and the discharge hopper 101 from clogging.

[0033] The working principle of this utility model is as follows: Open the lid 103 and pour the coffee beans to be ground into the storage hopper 102. The coffee beans then pass through the storage hopper 102 and the discharge hopper 101 into the feeding pipe 104, and then into the grinding hopper 201. The inner wall of the grinding hopper 201 is equipped with a grinding groove. The drive motor 202 is a servo motor, model SGM7G-55A6C6E. The output end of the motor 202 rotates, which drives the rotating shaft 203 to rotate. The rotation of the rotating shaft 203 drives the first grinding disc 204 and the third grinding disc 206 to rotate, which work together with the second grinding disc 205 and the fourth grinding disc 207 to grind the coffee beans.

[0034] When grinding stops, drive the two electric push rods 105 to extend and cause the two openings 106 to slide relative to each other, so that the openings 106 close and stop coffee beans from entering the grinding hopper 201. Place the coffee powder cup in the groove at the upper end of the cup holder 301 and drive the two electric push rods 303 to retract and cause the two openings 304 to separate relative to each other, so that the openings 304 open and coffee powder can fall from the outlet 302 into the coffee powder cup.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
