[0002] Up to now, the traditional machines or appliances for making soy milk or grinding powder are mainly of the following three types: 1. The ancient push-pull stone mill. This method mainly uses manpower or stored power to rotate the stone mill for grinding. The disadvantages are that the product is bulky, the grinding efficiency is low, and it is time-consuming and labor-intensive. 2. Household blade beating-type pulping machine, which is represented by soy milk machine products. It uses high-speed rotating blades to cut grain raw materials (such as soybeans) into small particles. However, this type of pulping machine does not make pulp by grinding. The main disadvantage of this type of product is that it targets a single object and a limited range. It is difficult to produce fine slurry in a short time. The produced slurry is relatively rough, and most of it still needs to be filtered to have a better taste. 3. Industrial large-scale electric heating grinder. The main disadvantages of this machine are large size, high noise, high energy consumption and high cost.

[0031] In order to better understand the purpose, structure and function of the present invention, Figure 1-2 , a grinding machine of the present invention is further described in detail.

[0032] like Figure 1As shown, the present invention provides a grinder for grinding required food materials into particles and controlling the size of the particles. The grinder mainly includes a shell 2, a cover 1 is connected to the shell 2, a rotating structure is provided on the cover 1, and a grinding assembly 5 is connected to the rotating structure. The grinder has a first usage state and a second usage state. A heating pot 6 is provided on the shell 2, and a grinding assembly 5 is provided on the cover 1. The grinding assembly 5 includes a grinding ball 51, and a ball head 55 is embedded in the grinding ball 51. When the grinding ball 51 and the ball head 55 are relatively stationary, the grinding assembly 5 stir-fries the material to be ground to form a first usage state; when the grinding ball 51 and the ball head 55 rotate relatively, the grinding assembly 5 grinds the material to be ground to form a second usage state.

[0033] like Figure 3 As shown, the side wall of the upper cover is rotatably connected to the shell 2, and the outer walls of the shell 2 and the upper cover can be set to be circular, or other shapes, as long as the outer edge of the upper cover and the outer edge of the shell 2 can be completely fastened and adapted, and no special limitation is made here.

[0034] like Figure 2 As shown, the rotating structure includes a motor 3, which is fixedly connected to the cover body 1. The bottom surface of the motor 3 is provided with a motor 3 shaft, and the motor 3 shaft is rotatably connected to the turntable 4, so that the rotation of the motor 3 drives the turntable 4 to rotate.

[0035] In order to connect the turntable 4 and the grinding assembly 5, a connecting groove is provided on the turntable 4. The connecting groove is arranged on the edge of the turntable 4. At the same time, the openings of the connecting grooves are the same, and the openings of the connecting grooves are outward, away from the center of the circle, so that it is convenient to install the grinding assembly 5 on the connecting groove. Holes are provided on the opposite side walls of the connecting groove, and fixing rods are provided on the two opposite holes, so that the grinding assembly 5 is rotatably connected.

[0036] The grinding assembly 5 is rotatably connected to the turntable 4. The rotation of the turntable 4 synchronously drives the grinding assembly 5 to rotate, thereby being able to stir-fry or grind the food. The grinding assembly 5 has two functions, namely, stir-frying the food and grinding the food, thereby meeting the different food needs of different people.

[0037] like Figure 4 As shown, the grinding assembly 5 includes a grinding ball 51, and a receiving groove 53 is provided on the top of the grinding ball 51. A ball head 55 is rotatably connected in the receiving groove 53. The ball head 55 and the receiving groove 53 are hinged, so that the ball head 55 can rotate in the receiving groove 53 and drive the grinding ball 51 to rotate.

[0038] Furthermore, the ball head 55 is a hemisphere, so that the hemispherical surface can rotate 360° in the accommodating groove 53 without being restricted by the structure and can rotate freely at various angles. The upper surface of the ball head 55 is a plane, and the upper surface of the ball head 55 is fixedly connected to the connecting rod 54, and the connecting rod 54 is fixedly connected to the connecting block 56. The connecting block 56 is provided with a connecting hole 561, so that the connecting hole 561 and the fixed rod of the turntable 4 are rotated to match. The aperture of the connecting hole 561 is larger than the diameter of the fixed rod, and the grinding assembly 5 swings on the turntable 4.

[0039] Some ingredients to be ground have high humidity and need to be dried and stir-fried before grinding. At this time, the grinding component 5 needs to be stir-fried before grinding. Some Chinese herbal medicines need to be heated and stir-fried before grinding. In order to realize the stir-frying and grinding functions to meet the use of the grinder by different users, the grinding component 5 is provided with two functions of stir-frying and grinding, both of which are realized by the stop switch set on the grinding component 5.

[0040] The anti-rotation switch includes a push rod 52 provided on the grinding ball 51 and an anti-rotation block 57 provided on the ball head 55, and the stir-frying and grinding functions are achieved through the cooperation of the two.

[0041] The top of the grinding ball 51 is set as a concave surface concave toward the center of the ball, and a push rod 52 is set on the concave surface on one side of the accommodating groove 53. The push rod 52 includes an inclined portion, one end of the inclined portion extends toward the center of the ball and is connected to a horizontal portion. A spacing is set between the horizontal portion and the concave surface at the top of the center of the ball, and the horizontal portion extends to above the accommodating groove 53.

[0042] A groove 551 is provided on the upper surface of the ball head 55. A spring 571 is connected to the groove 551. A stop block 57 is connected to the spring 571. The stop block 57 includes a bottom surface and side plates on opposite sides of the bottom surface, one end of which is fixedly connected. The cross-section of the stop block 57 is triangular. The vertical distance between the top and bottom surfaces of the stop block 57 is greater than the distance between the push rod 52 and the concave surface. The stop block 57 includes the bottom plate and the side plates, forming a first angle and a second angle. The first angle is an acute angle, and the vertical distance between the inclined surface of the acute angle and the horizontal plane is less than the vertical distance between the push rod 52 and the concave surface. Therefore, when the push rod 52 first contacts the first angle, the lower surface of the push rod 52 abuts the inclined surface of the stop block 57. Due to the elastic force, the stop block 57 is pressed tightly into the groove 551, and the grinding ball 51 can rotate with the rotation of the connecting rod 54. When the push rod 52 first contacts the second angle, because the second angle is greater than the first angle, the lower surface of the push rod 52 cannot contact the inclined surface of the stop block 57. The side surface of the push rod 52 abuts the inclined surface of the stop block 57, preventing the stop block 57 from being pressed into the groove 551, and the grinding ball 51 cannot rotate. During grinding, the grinding ball 51 rotates with the rotation of the connecting rod 54. During stir-frying, the push rod 52 rotates to the stop switch, preventing rotation.

[0043] like Figure 5 As shown, further, a recess 511 is provided on the circumferential surface of the grinding ball 51. Preferably, 3 / 4 of the circumferential surface of the grinding ball 51 is set as a spherical surface, and 1 / 4 of the grinding ball 51 is provided with the recess 511, so that when grinding, 3 / 4 of the rough surface is used to complete the grinding of the food, and when stir-frying, 1 / 4 of the concave surface is used to push the food to rotate, thereby completing the stir-frying of the food.

[0044] like Figure 6 As shown, the heating pot 6 arranged on the shell 2 is in the shape of an ordinary pot body, the pot body is arranged in a ring shape, the middle part of the heating pot 6 is arranged as a through hole 63, and an inner concave surface 61 is extended upward along the inner wall of the through hole 63, so that the grinding balls 51 of the stir-fry grinding balls 51 rotate around the center of the pot body in the heating pot 6, and a plurality of discharge holes 62 are arranged on the inner concave surface 61, so that the ground particles are squeezed into the through hole 63.

[0045] A collecting box 8 is provided below the through hole 63 of the heating pot 6 for collecting the ground particles.

[0046] A heating pipe is provided in the heating pot 6 for heating the pot body, thereby heating the food in the pot. A temperature sensing package and a temperature limiter are also provided in the heating pot 6 to control the heating temperature of the heating pot 6 according to the set temperature, thereby ensuring reliable heating and accurate temperature control.

[0047] like Figure 7 As shown, in order to control the size of the particles of the required ground food, the size of the ground particles is controlled by adjusting the filter structure 7. The filter structure 7 includes a support plate 74. A filter plate 75 is provided on the edge of the support plate 74. The filter plate 75 is also configured to be concave, so that the filter plate 75 is installed on the inner side of the concave surface 61 of the heating pot 6. The support plate 74 is a circular plate-shaped structure. The diameter of the support plate 74 is larger than the aperture of the through hole 63 of the heating pot 6. Therefore, the edge of the support plate 74 overlaps the hole wall of the through hole 63, fixing the filter structure 7 on the heating pot 6. A handle is provided on the upper surface of the support plate 74, which can adjust the size of the filter hole, thereby controlling the size of the particles of the ground food.

[0048] Furthermore, the filter plate 75 is provided with filter holes of varying sizes, thereby adjusting the size of the ground particles. The filter holes include a first filter hole 72 and a second filter hole 73, each having different apertures. The filter plate 75 is provided with multiple groups of filter holes, each with a different aperture. The discharge hole 62 has an aperture larger than the largest aperture among the filter holes, thereby adjusting the size of the ground particles. The filter plate 75 is provided with multiple zones, each with a group of filter holes. Each zone has the same aperture size, while adjacent zones have different apertures. Aligning the filter holes on the filter plate 75 with the discharge hole 62 allows the desired particle size to be ground. Once the ground material reaches a size that allows it to pass through the aperture of the filter plate 75, it falls into the collection box 8, completing the controllable setting of the ground particle size. The faster the motor 3 rotates, the greater the centrifugal force of the grinding balls 51, the larger the friction gap, the less complete the grinding, and the larger the ground particles. The size of the ground particles can be controlled by controlling the motor 3 speed and adjusting the filter structure 7.

[0049] The present invention also provides a grinder, which also includes a control device. The control device is arranged on the housing 2 to control the rotation direction and speed of the motor 3, thereby achieving stir-frying and grinding and controlling the size of the ground particles.

[0050] The present invention also provides another embodiment that can also achieve the above-mentioned grinding function. The grinding ball 51 is set to a spherical surface, which can achieve bidirectional grinding. When the turntable 4 rotates clockwise, the grinding ball 51 achieves sliding friction grinding. When the turntable 4 rotates counterclockwise, the grinding ball 51 achieves counterclockwise rolling friction, thereby improving the grinding efficiency. At the same time, a guide structure is provided in the cavity of the heating pot 6. The guide structure includes an annular plate structure. The lower surface of the annular plate structure is provided with a support column, so that the guide structure is fixed to the bottom of the heating pot 6, limiting the movement of the grinding ball 51 in the guide structure, and limiting the grinding ball 51 from performing centrifugal motion. The other structures are the same as those in the above-mentioned embodiment.

[0051] The present invention provides a grinder that can achieve multiple uses in one machine. The grinding method is designed to be closer to the traditional extrusion grinding method, which is safer and more reliable. A heating tube is provided in the heating pot 6 to meet the needs of different users for processing different food ingredients. The user can select the temperature, humidity during grinding, and the particle size of the food after grinding, truly meeting all the user's needs for grinding and processing food ingredients. By controlling the filter pore size of the filter layer and the speed of the motor 3, the centrifugal force is controlled to control the size of the ground particles. The heating function can meet the food processing needs of stir-frying first and then grinding. In addition to the grinding function, new functions such as heating, stir-frying, juicing, and filtering are added.

[0052] It will be understood that the present invention is described by way of some embodiments, and it will be appreciated by those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
