Technical Field

[0001] The invention relates to the field of hand-cranked coffee bean grinders, in particular to a portable hand-cranked coffee bean grinder. Background Art

[0002] In the process of crushing and grinding coffee beans, after the coffee beans are crushed into granular coffee beans, the granular coffee beans need to be ground into powder. The resistance encountered when grinding the granular coffee beans into powder is smaller than the resistance encountered when crushing the coffee beans into granular coffee beans. At this time, the rotation speed of the crushing and grinding structure is a fixed value. When grinding the granular coffee beans into coffee powder, it needs to rotate more times, which is more laborious and affects the efficiency of the coffee bean crushing and grinding. Summary of the invention

[0003] In order to overcome the disadvantage that the rotation speed of the crushing and grinding component structure is a fixed value, and when grinding granular coffee beans into coffee powder, more rotations are required, which is more laborious, the present invention provides a portable hand-cranked coffee bean grinder.

[0004] The technical scheme of the present invention is: a portable hand-cranked bean grinder, comprising a bean bin, an annular grinding disc, a collecting container, a connecting rod, a telescopic rocker, an annular frame, a shielding plate I and a shielding plate II; the bean bin is detachably connected to the annular grinding disc; the annular grinding disc is detachably connected to the collecting container; a detachable connecting rod in the bean bin; a detachable telescopic rocker on the connecting rod; an annular frame is rotatably connected to the bean bin; a shielding plate I is fixedly connected in the annular frame; a shielding plate II is fixedly connected to the bean bin, and the shielding plate II cooperates with the shielding plate I to shield the entrance of the bean bin; and also comprises a limiting knob, a spring, a conical grinding disc I, a conical grinding disc II, a gear ring, a mounting plate, a gear I and Gear II; conical grinding disc I and conical grinding disc II are sleeved on the connecting rod, and conical grinding disc I and conical grinding disc II are located in the annular grinding disc; a gear ring is fixedly connected to the bottom of conical grinding disc I; a mounting plate is fixedly connected to the bottom of the gear ring; a number of gears I are rotatably connected to the mounting plate, and gear I meshes with the gear ring; gear II is fixedly connected to conical grinding disc II, and gear II meshes with all gears I, a cylinder is provided at the bottom of gear II, and the cylinder of gear II penetrates the mounting plate and is slidably connected to conical grinding disc II; a spring is provided at the bottom of the mounting plate, and the spring is located between conical grinding disc II and the mounting plate; a limiting knob is rotatably connected to the bottom of the cylinder of gear II, and the limiting knob is located below conical grinding disc II.

[0005] Optionally, the bean bin is made of transparent material.

[0006] Optionally, a limiting buckle is provided on the bean bin, and the limiting buckle is used to fix the telescopic rocker in the storage state.

[0007] Optionally, the surface of the annular grinding disc is provided with an anti-slip layer.

[0008] Optionally, a plurality of slide grooves are provided on the annular grinding disc, and a rubber connecting column is provided on the collecting container, and the collecting container slides in the slide groove through the rubber connecting column, and all the slide grooves are provided with an inlet and outlet, a fixed end I and a fixed end II.

[0009] Optionally, a rubber pad is provided at the bottom of the collecting container.

[0010] Optionally, the telescopic rocker grip is provided with an anti-slip layer.

[0013] Optionally, fan blades are also included; the fan blades are fixedly connected to the conical grinding disc II, and the fan blades are located between the spring and the conical grinding disc II.

[0014] The beneficial effects of the present invention are as follows: the present invention removes the telescopic rocker from the connecting rod, buckles the telescopic rocker on the bean bin limiting buckle, rotates the collecting container, and transfers the rubber connecting column on the collecting container from the fixed end II to the fixed end I. At this time, the collecting container wraps the annular grinding disc, reducing the space required for the present invention and facilitating carrying.

[0015] The present invention drives gear I through a gear ring, gear I drives gear II, and conical grinding disc II rotates following gear II, so that conical grinding disc I and conical grinding disc II rotate in different directions, so that coffee beans can be crushed and ground better. The gear teeth on the gear ring are larger than those on gear II, and the rotation speed of the gear ring is lower than that of gear II.

A cylinder is provided at the bottom of gear II106, and the cylinder of gear II106 penetrates the mounting plate 104 and is slidably connected to the conical grinding disc II102; a spring 10 is provided at the bottom of the mounting plate 104, and the spring 10 is located between the conical grinding disc II102 and the mounting plate 104; a limiting knob 7 is rotatably connected to the bottom of the cylinder of gear II106, and the limiting knob 7 is located below the conical grinding disc II102.

[0021] The bean bin 1 is made of transparent material, which is convenient for observing the condition of the coffee beans.

[0022] The bean bin 1 is provided with a limiting buckle, which is used to fix the telescopic rocker 5 in the storage state, thereby reducing the space occupied by the present invention.

[0023] The surface of the annular grinding disc 2 is provided with an anti-slip layer to improve the grip feel.

[0024] Two slide grooves 21 are formed on the annular grinding disc 2, and a rubber connecting column is provided on the collecting container 3. The collecting container 3 slides in the slide groove 21 through the rubber connecting column. All the slide grooves 21 are provided with an inlet and outlet 211, a fixed end I 212 and a fixed end II 213.

[0025] A rubber pad is provided at the bottom of the collecting container 3 to increase stability.

[0026] The grip of the telescopic rocker 5 is provided with an anti-skid layer to prevent the user's palms from sweating and slipping.

[0027] The annular frame 6 is in a trumpet shape, which is convenient for adding coffee beans.

[0028] A sealing layer is provided on the shielding plate I8 and the shielding plate II9 to improve the sealing performance of the present invention.

[0029] When the user uses a hand-cranked bean grinder to make coffee, the coffee beans need to be crushed and ground into coffee powder. In the initial state, the shielding plate I8 and the shielding plate II9 cooperate with each other to shield the entrance of the bean bin 1. The user needs to rotate the annular frame 6 first, and the shielding plate I8 rotates accordingly. When the shielding plate I8 overlaps with the shielding plate II9, the rotation of the annular frame 6 is stopped. At this time, the shielding plate I8 no longer blocks the entrance of the bean bin 1, and then a proper amount of coffee beans is put into the bean bin 1. The coffee beans are accumulated in the annular grinding disc 2, and then the user rotates the annular frame The frame 6 and the baffle plate I8 are used to block the entrance of the bean bin 1 again. Then, the user holds the telescopic rocker 5 and starts to rotate. The connecting rod 4, the conical grinding disc I101 and the conical grinding disc II102 rotate accordingly. During the rotation of the conical grinding disc I101 and the conical grinding disc II102, the coffee beans are crushed and ground. The coffee beans are first crushed into granular coffee beans, and then the granular coffee beans are ground into coffee powder. The coffee powder falls into the collecting container 3, and the crushing and grinding of the coffee beans is completed.

[0030] By opening a slide groove 21 on the annular grinding disc 2, a rubber connecting column is provided on the collecting container 3, and the collecting container 3 slides in the slide groove 21 through the rubber connecting column. The slide groove 21 is provided with an entrance and exit 211, a fixed end I 212 and a fixed end II 213. When the present invention is not in use, the telescopic rocker 5 is removed from the connecting rod 4, and the telescopic rocker 5 is buckled on the limiting buckle of the bean bin 1. At this time, the rubber connecting column on the collecting container 3 is located at the fixed end II 213, and the collecting container 3 is rotated to transfer the rubber connecting column on the collecting container 3 from the fixed end II 213 to the fixed end I 212. At this time, the collecting container 3 wraps the annular grinding disc 2, reducing the space required for the present invention and being easy to carry. When the collecting container 3 needs to be removed from the annular grinding disc 2, it only needs to pull the rubber connecting column on the collecting container 3 out of the entrance and exit 211 to complete the disassembly of the collecting container 3.

[0031] Considering that after the coffee beans are crushed into granular coffee beans by the conical grinding discs Ⅰ101 and Ⅱ102, the coffee beans and the granular coffee beans are mixed together, the conical grinding discs Ⅰ101 and Ⅱ102 crush the coffee beans and the granular coffee beans at the same time, while the conical grinding discs Ⅰ101 and Ⅱ102 cannot effectively refine the granular coffee beans again when crushing the coffee beans. It is necessary to wait until most of the coffee beans are crushed into granular coffee beans before the conical grinding discs Ⅰ101 and Ⅱ102 can effectively refine the granular coffee beans, and the efficiency of coffee bean crushing and grinding is affected. By setting the crushing and grinding component to the conical grinding discs Ⅰ101 and Ⅱ102 1 and a conical grinding disc II 102. After the coffee beans are crushed into granular coffee beans by the conical grinding disc I 101, the granular coffee beans fall downward from the gap between the conical grinding disc I 101 and the annular grinding disc 2, and the granular coffee beans fall between the conical grinding disc II 102 and the annular grinding disc 2. The granular coffee beans are ground during the rotation of the conical grinding disc II 102 to avoid mixing the coffee beans and the granular coffee beans, which would affect the efficiency of the coffee bean crushing and grinding. In addition, by the above-mentioned method of separately processing the coffee beans and the granular coffee beans, when the coffee beans are initially crushed into granular coffee beans, the granular coffee beans can be effectively refined, thereby improving the efficiency of the coffee bean crushing and grinding.

[0032] When the grinding accuracy of the coffee powder needs to be improved, the collecting container 3 is removed from the annular grinding disc 2, and the user turns the limiting knob 7 to push the conical grinding disc II 102. The spring 10 begins to shrink under the push of the conical grinding disc II 102, thereby reducing the gap between the conical grinding disc II 102 and the annular grinding disc 2, thereby grinding the coffee powder more finely.

[0033] However, considering that it takes more turns to grind granular coffee beans into coffee powder, which is more laborious, a gear ring 103 is added to the bottom of the conical grinding disc Ⅰ 101, a mounting plate 104 is added to the bottom of the gear ring 103, a gear Ⅰ 105 is provided on the mounting plate 104, the gear Ⅰ 105 is meshed with the gear ring 103, a gear Ⅱ 106 is added to the conical grinding disc Ⅱ 102, the gear Ⅱ 106 is meshed with the gear Ⅰ 105, a cylinder is provided at the bottom of the gear Ⅱ 106, the cylinder of the gear Ⅱ 106 penetrates the mounting plate 104 and is slidably connected to the conical grinding disc Ⅱ 102, the gear teeth on the gear ring 103 are larger than the gear Ⅱ 106, When the gear ring 103 rotates following the conical grinding disc I101, the gear ring 103 drives the gear I105, the gear I105 drives the gear II106, and the conical grinding disc II102 rotates following the gear II106, so that the conical grinding disc I101 and the conical grinding disc II102 rotate in different directions, so as to better crush and grind the coffee beans. Moreover, the gear teeth on the gear ring 103 are larger than those of the gear II106, and the rotation speed of the gear ring 103 is lower than that of the gear II106, while the conical grinding disc II102 is connected to the gear II106, so as to speed up the grinding of granular coffee beans and save the user's energy.

[0034] Example 2 On the basis of Example 1, Figure 4-Figure 6 As shown, it also includes a fan blade 111; the fan blade 111 is fixedly connected to the conical grinding disc II 102, and the fan blade 111 is located between the spring 10 and the conical grinding disc II 102.

[0035] By adding a fan blade 111 to the conical grinding disc II 102, the fan blade 111 replaces the conical grinding disc II 102 and is connected to the gear II 106. When the conical grinding disc II 102 rotates, the fan blade 111 rotates accordingly. When the fan blade 111 rotates, an airflow is generated. The airflow flows in the bean bin 1 and the annular grinding disc 2, so that the coffee powder remaining on the annular grinding disc 2, the conical grinding disc I 101 and the conical grinding disc II 102 begins to fall off. The fallen coffee powder falls downward, so that more coffee powder can be transferred to the collection container 3, thereby improving the yield of coffee powder.

[0036] It should be noted that when the coffee beans are crushed and ground, the airflow generated by the rotation of the fan blades 111 will drive the coffee powder to transfer from the entrance of the bean bin 1 to the outside, causing waste. Before crushing and grinding the coffee beans, after adding the coffee beans, the user rotates the annular frame 6 and the baffle plate Ⅰ8 to allow the baffle plate Ⅰ8 and the baffle plate Ⅱ9 to block the entrance of the bean bin 1 again to avoid the airflow generated by the rotation of the fan blades 111 driving the coffee powder to transfer from the entrance of the bean bin 1 to the outside, causing waste.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
