[0040] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] Reference Figures 1 to 7 As shown, a powder adding mechanism according to an embodiment of the present invention is provided with a discharging assembly 100, which includes a discharging portion 110, a quantitative material taking member 120 and a material storage container 130. The discharging portion 110 has a feed port and a discharge port 114 connected to the feed port. The quantitative material taking member 120 is rotatably mounted in the discharging portion 110, and the quantitative material taking member 120 is located at a connecting position between the feed port and the discharge port 114. The quantitative material taking member 120 is provided with at least one quantitative groove 121, and the quantitative material taking member 120 can move between a first position and a second position during the rotation process. When the quantitative groove 121 is located at the first position, it faces the feed port, and when the quantitative groove 121 is located at the second position, it faces the discharge port 114. The material storage container 130 is detachably mounted on the discharging portion 110 and is connected to the feed port. A first airflow channel 111 is formed on the side wall of the material discharging portion 110 , and an air outlet of the first airflow channel 111 is located between the quantitative material taking component 120 and the material discharging port 114 .

[0042] The storage container 130 is used to temporarily store powder, i.e., powdered seasonings. The powder enters the feed port of the discharging assembly 100 through the storage container 130. At this time, the quantitative slot 121 of the quantitative material taking part 120 is in the first position, i.e., facing the feed port, so the powder can fall onto the quantitative material taking part 120 and fill the quantitative slot 121. When the quantitative material taking part 120 rotates to the second position, the powder in the quantitative slot 121 falls to the discharge port 114 under the action of gravity, and is poured into the pot. During the process of adding powder, the air outlet of the first air flow channel 111 blows out air flow to disperse the floating water vapor in the pot, to prevent water vapor from entering the quantitative slot 121 on the quantitative material taking part 120 or entering the storage container 130 to a certain extent, and to prevent the powder from solidifying on the quantitative slot 121 or in the powder container and affecting the accuracy of powder addition. The above-mentioned material adding mechanism can prevent the powder from solidifying to a certain extent, realize accurate feeding, and ensure the taste of food.

[0043] Specifically, the rotation speed of the quantitative material taking member 120 can be controlled to set the amount of powder material taken within a set time.

[0044] It is understandable that a plurality of quantitative grooves 121 can be provided, and the quantitative material taking member 120 can take materials multiple times by rotating once, thereby improving the efficiency of adding powder within a set time.

[0045] Reference Figures 3 to 5 As shown, it can be understood that the discharging part 110 includes a mounting seat 112 and a cover 113, and the cover 113 is detachably arranged on the mounting seat 112 by magnetic attraction. The cover 113 is disassembled to realize the disassembly of the quantitative material taking part 120, and the discharging port 114 is located on the side wall of the cover 113 at one end away from the mounting seat 112. When the cover 113 is disassembled, the quantitative material taking part 120 can be exposed. Since the quantitative slots 121 of different capacities are provided, the amount of powder added to each quantitative slot 121 can be accurately controlled, and the powder adding accuracy can be improved. Therefore, in this embodiment, the discharging part 110 is set as two parts of the mounting seat 112 and the cover 113, which is convenient for maintaining or replacing the quantitative material taking part 120. In addition, if the powder is blocked on the quantitative material taking part 120, the cover 113 can be directly disassembled, and then the quantitative material taking part 120 can be cleaned.

[0046] Reference Figure 3 , Figure 5 and Figure 7 As shown, it can be understood that the quantitative material picking member 120 includes a rolling body 122, and a tube body 123 is provided at both ends of the rolling body 122 along the rotating axis, and a first magnetic body 124 is provided in each tube body 123; the mounting seat 112 is provided with a first ferromagnet 115 for the first magnetic body 124, and the inner cavity of the cover body 113 corresponds to the first magnetic body 124.

[0047] Specifically, the quantitative material picking piece 120 is made of plastic material and is not ferromagnetic, but a first magnetic body 124 is provided at both ends of the quantitative material picking piece 120. During installation, the first magnetic body 124 cooperates with the first ferromagnet 115 on the mounting seat 112 to achieve stable assembly and convenient assembly and disassembly. In order to facilitate assembly and disassembly, the inner cavity of the cover body 113 is also provided with a first ferromagnet 115.

[0048] It is understandable that the tube body 123 of the quantitative material taking piece 120 can also be set as a block of ferromagnetic material, and the mounting seat 112 and the cover body 113 can be replaced with magnetic bodies; or magnetic bodies can be set in the tube body 123, the mounting seat 112, and the cover body 113, as long as magnetic attraction can be achieved.

[0049] Figures 1 to 3 As shown, it can be understood that the powder adding mechanism also includes a base assembly 200, which is detachably connected to the discharge assembly 100 through magnetic attraction, and the base assembly 200 is provided with a driving part, and when the discharge assembly 100 is connected to the base assembly 200, the driving part is connected to the quantitative material taking part 120. In the present embodiment, the powder adding mechanism is divided into two parts, namely, a base assembly 200 and a discharging assembly 100. The heavy driving part is arranged in the base assembly 200. When powder needs to be filled or the discharging assembly 100 needs to be cleaned, there is no need to disassemble the entire powder adding mechanism. Only the discharging assembly 100 needs to be removed from the base assembly 200, and then the powder is replenished or the discharging assembly 100 needs to be cleaned. The discharging assembly 100 and the base assembly 200 in the present embodiment are connected and disassembled by magnetic attraction. When disassembling, the discharging assembly 100 can be removed from the base assembly 200 by holding it. When assembling, the discharging assembly 100 is held so that the first docking portion and the second docking portion are aligned to realize magnetic attraction and engagement, and the discharging assembly 100 can be installed on the base assembly 200. The assembly and disassembly is convenient and quick, which greatly improves the assembly and disassembly efficiency, and can easily load materials and clean the discharging assembly 100, saving manpower.

[0050] Reference Figure 2 and Figure 3 As shown, it can be understood that a positioning boss 201 is provided on one side of the base assembly 200 close to the discharging assembly 100, and a second magnetic body is embedded in the positioning boss 201; a mounting groove 116 is provided on one side of the discharging assembly 100 close to the base assembly 200, and the mounting groove 116 is arranged corresponding to the positioning boss 201, and the discharging assembly 100 is provided with a second ferromagnetic body 117 in the mounting groove 116. The arrangement of the positioning boss 201 and the mounting groove 116 allows the relative position of the base assembly 200 and the discharging assembly 100 to be quickly positioned, thereby improving the assembly and disassembly efficiency.

[0051] Specifically, the sum of the protruding distance of the positioning boss 201 and the thickness of the second magnetic body is equal to the depth of the mounting groove 116, so that the second magnetic body contacts the positioning boss 201, and the discharge assembly 100 and the base assembly 200 are tightly matched, and the positioning boss 201 is not exposed, thereby improving the integrity of the structure.

[0052] Reference Figure 8 As shown, it can be understood that the powder adding mechanism also includes a flip assembly 300, and the flip assembly 300 is drivingly connected to the base assembly 200. When it is not necessary to add powder to the pot of the cooking machine, the storage container 130 is located below the discharge portion 110, and the powder is temporarily stored in the storage container 130; when it is necessary to add powder to the pot of the cooking machine, the flip assembly 300 can be used to drive the discharge assembly 100 to flip, so that the discharge portion 110 is located below the storage container 130, which is convenient for the powder to be discharged under the action of gravity; and when the flip assembly 300 flips the discharge assembly 100, it can flip the powder in the storage container 130, and break up the powder in the storage container 130 to a certain extent, thereby avoiding the powder from agglomerating and affecting the feeding accuracy, and ensuring the taste of the food.

[0053] Reference Figure 5 As shown, it can be understood that two inner concave positions 118 are provided at one end of the discharging assembly 100 away from the base assembly 200, and the two inner concave positions 118 are relatively arranged on the two side walls of the discharging assembly 100. The inner concave positions 118 are arranged to provide a fulcrum when disassembling the discharging assembly 100. During assembly and disassembly, the thumb and index finger are respectively located at the two inner concave positions 118, saving manpower.

[0054] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, it can be understood that the base assembly 200 is provided with a accommodating cavity 202 with an opening and a substrate 203 that closes the opening, and the driving part includes a first driving motor 204, the first driving motor 204 is located in the accommodating cavity 202 and is fixed on the substrate 203, and the output shaft of the first driving motor 204 passes through the substrate 203 and is connected to the quantitative material taking part 120; the substrate 203 is provided with a second air flow channel 205, one end of the second air flow channel 205 is connected to the first air flow channel 111, and the other end is connected to the air supply assembly.

[0055] Reference Figure 7As shown, specifically, when the quantitative material taking component 120 is located in the base assembly 200, a spline sleeve 125 is provided in the tube body 123 close to the base assembly 200, and a spline is provided at the shaft end of the output shaft of the first drive motor 204. As the installation of the discharge component 100 on the base assembly 200 is completed, the spline at the shaft end of the output shaft of the first drive motor 204 is docked with the spline sleeve 125 in the quantitative material taking component 120.

[0056] Reference Figure 2 and Figure 6 As shown, it can be understood that the air inlet of the first airflow channel 111 and the air outlet of the second airflow channel 205 are arranged in a staggered manner and are connected through the buffer groove 206. The buffer groove 206 is provided on the base assembly 200. During the turning process of the powder adding mechanism, it is very likely that a small amount of powder will enter the interior of the base assembly 200 along the second airflow channel 205 and the first airflow channel 111. In order to reduce the possibility of salt, monosodium glutamate and other powders corroding the driving part inside the base assembly 200, the buffer groove 206 is provided in this embodiment. The groove wall of the buffer groove 206 has a certain blocking effect on the powder, and to a certain extent, the powder is prevented from entering the interior of the base assembly 200.

[0057] Reference Figure 3 As shown, it can be understood that a vibration motor 207 is provided on the substrate 203, and the vibration motor 207 is located in the accommodating cavity 202. The provision of the vibration motor 207 allows the powder in the storage container 130 to be vibrated, further preventing the powder from solidifying, and the vibration motor 207 accelerates the falling speed of the powder in the storage container 130, so that the material taking process is fast and continuous.

[0058] An embodiment of the present invention further relates to a cooking machine, comprising the powder adding mechanism as in the above embodiment.

[0059] In the invention of the above embodiment, the storage container 130 is used to temporarily store powder, i.e., powdered seasonings. The powder enters the feed port of the discharging assembly 100 through the storage container 130. At this time, the quantitative slot 121 of the quantitative material taking part 120 is in the first position, i.e., facing the feed port, so the powder can fall onto the quantitative material taking part 120 and fill the quantitative slot 121. When the quantitative material taking part 120 rotates to the second position, the powder in the quantitative slot 121 falls to the discharge port 114 under the action of gravity, and is poured into the pot. In the process of adding powder, the air outlet of the first air flow channel 111 blows out air flow to disperse the floating water vapor in the pot, to prevent water vapor from entering the quantitative slot 121 on the quantitative material taking part 120 or entering the storage container 130 to a certain extent, and to prevent the powder from solidifying on the quantitative slot 121 or in the powder container and affecting the accuracy of adding powder. The above material adding mechanism can prevent the solidification of powder to a certain extent, realize accurate feeding, and ensure the taste of food.
