It should be noted that for ease of reference, Figures 1 to 3 The driving source of the driving assembly 4 is not shown in the figure. The material box 10 has a material chamber 11 and a discharge port 12. The material chamber 11 is used to hold powder. The discharge port 12 is connected to the material chamber 11. The powder in the material chamber 11 is discharged to the pushing assembly 2 through the discharge port 12. The pushing assembly 2 is connected to the material box 10, and the pushing assembly 2 is at least partially arranged in the material chamber 11. The pushing assembly 2 is used to push the powder at the discharge port 12 to the outside of the powder device. In other words, the powder in the material box 10 first goes from the material chamber 11 to the discharge port 12, and then passes through the discharge port 12 to the pushing assembly 2. Finally, it is transported to the outside of the powder device by the moving parts (such as the pushing screw 21) in the pushing assembly 2. It should be noted that the present application does not limit the movement form of the pushing assembly 2. The pushing assembly 2 can push the powder in a rotating or swinging manner, or in a translational manner, as long as the pushing assembly 2 can push the powder at the discharge port 12 to the outside of the powder device.

[0051] Reference Figure 3, the stirring component 3 is at least partially arranged in the material chamber 11, and the stirring component 3 is used to stir the powder in the material chamber 11, so as to disperse the powder that is agglomerated due to moisture, and at the same time, reduce the risk of the powder hanging on the wall, so that the powder can fully fall and pass through the discharge port 12. It should be noted that the stirring component 3 can be vertically inserted in the material chamber 11. Of course, the stirring component 3 can also be horizontally inserted in the material chamber 11 as shown in some embodiments of the schematic diagram of the present application; the stirring component 3 can move horizontally or swing, or can rotate as shown in some embodiments of the schematic diagram of the present application. The present application does not limit the specific setting position and movement form of the stirring component 3, as long as the stirring component 3 can provide a stirring function for the powder in the material chamber 11. In some other embodiments, the stirring component 3 can also be arranged outside the material chamber 11, and the agglomerated powder can be dispersed by means such as vibration or shaking. In some embodiments of the present application, the stirring component 3 is disposed in the material holding chamber 11 so as to be in full contact with the powder material, thereby facilitating full stirring of the powder material that has agglomerated due to moisture, thereby improving the consistency of the amount of powder material output.

[0052] Figure 4 It is an exploded view of the powder device in the embodiment of the present application, wherein: Figure 4 The material box 10 is omitted. Figure 3 , the driving assembly 4 is arranged adjacent to the pushing assembly 2 and / or the stirring assembly 3, that is, in the embodiment in which the pushing assembly 2 and the stirring assembly 3 share the same driving source, the driving assembly 4 can be arranged adjacent to the stirring assembly 3, or can be arranged adjacent to the pushing assembly 2; in the embodiment in which the pushing assembly 2 and the stirring assembly 3 are respectively provided with a driving source, the driving assembly 4 is arranged adjacent to the pushing assembly 2 and the stirring assembly 3. And in combination with the above, it can be known that the driving assembly 4 can be driven by a rotating component (such as a motor), the driving assembly 4 can also be driven by a swinging component (such as a rotary cylinder), and the driving assembly 4 can also be driven by a translational component (such as a double-axis or three-axis cylinder). The present application does not limit the specific setting position and specific structure of the driving assembly 4, as long as the driving assembly 4 can drive the pushing assembly 2 and the stirring assembly 3 to move.

[0053] In an embodiment of the present application, a powder material device is provided, which includes a material box 10, a pushing assembly 2, a stirring assembly 3 and a driving assembly 4. The material box 10 has a material chamber 11 for containing powder material and a discharge port 12 connected to the material chamber 11. The powder material in the material chamber 11 flows from the discharge port 12 to the pushing assembly 2. The pushing assembly 2 is connected to the material box 10 and is at least partially disposed in the material chamber 11. The pushing assembly 2 is used to push the powder material at the discharge port 12 to the outside of the powder material device. The stirring assembly 3 is at least partially disposed in the material chamber 11 so as to be able to fully contact the powder material in the material chamber 11. The driving assembly 4 is disposed adjacent to the pushing assembly 2 and / or the stirring assembly 3. The driving assembly 4 can drive the pushing assembly 2 and the stirring assembly 3 so that the pushing assembly 2 moves and pushes the powder material to the outside of the powder material device. The stirring component 3 is used to stir the powder in the material chamber 11 so that the powder hanging on the wall falls fully, and the powder agglomerated due to moisture is dispersed, thereby reducing the risk of adding too much or too little powder, improving the accuracy of adding powder, and thus ensuring the stability of the cooking taste. The powder device in the embodiment of the present application is provided with a stirring component 3, and at least a part of the stirring component 3 is arranged in the material chamber 11 to fully stir the powder, thereby improving the accuracy of the powder device in adding powder.

[0054] In some embodiments, reference Figure 4 The stirring assembly 3 includes a stirring shaft 31 and a stirring member 32. The stirring shaft 31 is connected to the driving assembly 4, and the stirring shaft 31 is shaft-shaped, so the driving assembly 4 drives the stirring shaft 31 to rotate. The stirring member 32 is connected to the stirring shaft 31, and the stirring member 32 is protruded relative to the outer peripheral wall of the stirring shaft 31. A gap is formed between the outer wall surface of the protruding stirring shaft 31 and the outer peripheral wall of the stirring shaft 31. The powder alternately contacts the outer wall surface of the stirring shaft 31 and the outer peripheral wall of the stirring shaft 31 and rolls, thereby achieving "stirring". During the operation of the stirring assembly 3, the stirring shaft 31 and the stirring member 32 are in continuous and alternating contact with the powder. There is no need to reset or return to the original position. The powder can be rolled by rotating in place, and the stirring efficiency is higher.

[0055] In some embodiments, reference Figure 4, the stirring member 32 may be a spiral blade 321 spirally wrapped around the outer peripheral wall of the stirring shaft 31, the stirring member 32 may be a lever 322 protruding from the outer peripheral wall of the stirring shaft 31, or the stirring member 32 may be a structure composed of a spiral blade 321 and a lever 322. In the embodiment in which the stirring member 32 is set as a spiral blade 321, the setting area of ​​the spiral blade 321 is relatively large, and the total length of the stirring shaft 31 can be wrapped around for multiple turns, and the setting area of ​​the spiral blade 321 is relatively large, which is convenient for fully contacting the powder and fully stirring. In the embodiment in which the stirring member 32 is set as a lever 322, the lever 322 has a regular shape and is easy to process, and the lever 322 is small in size, and is not easy to touch the material box 10 and interfere with the rotation of the stirring shaft 31, thereby reducing the processing and design difficulty of the stirring assembly 3; on the other hand, because the lever 322 is small in size, a longer lever 322 can be set to make the powder roll fully. In the embodiment where the stirring member 32 is configured as a combination of a spiral blade 321 and a lever 322, the horizontal and vertical spaces in the material box 10 can be fully utilized to stir the powder more comprehensively. For example, in the embodiment where the stirring component 3 is horizontally arranged in the material box 10, the spiral blade 321 intercepts and stirs the powder horizontally, and the lever 322 lifts and stirs the powder vertically, so the stirring efficiency is high.

[0056] In some embodiments, reference Figure 4 The driving component 4 includes a driving member 41, a first transmission member 42 and a second transmission member 43. The driving member 41 is used to provide driving force. It should be noted that the present application does not limit the specific structure of the driving member 41. For example, the driving member 41 can be a servo motor, a stepper motor or a motor. The first transmission member 42 is connected to the stirring component 3, and the second transmission member 43 is connected to the pushing component 2. Among them, the driving member 41 is connected to the first transmission member 42 or the second transmission member 43, and the first transmission member 42 is connected to the second transmission member 43. That is to say, the first transmission member 42 and the second transmission member 43 share a driving member 41 and rotate synchronously, so that the pushing component 2 and the stirring component 3 rotate synchronously, saving energy, and simplifying the structure of the driving component 4 and the purchase cost of components. On the other hand, because the pushing component 2 feeds intermittently according to the cooking time and the type of food, the stirring component 3 is also started intermittently with the pushing component 2, which reduces energy consumption.

[0057] It should be noted that the present application does not limit the connection form between the first transmission member 42 and the second transmission member 43. For example, the first transmission member 42 and the second transmission member 43 may be various structural forms such as gear racks, synchronous wheels and synchronous belts, or gear meshing. In some embodiments shown in the schematic diagram of the present application, the first transmission member 42 and the second transmission member 43 are configured as a structure in which a driving gear and a driven gear mesh, so as to improve the precise transmission of the transmission torque in the driving assembly 4 and facilitate the synchronous rotation of the pushing assembly 2 and the stirring assembly 3.

[0058] In some embodiments, reference Figure 4 The driving assembly 4 also includes a first magnetic group 44 and a second magnetic group 45. The first magnetic group 44 is fixedly connected to the driving assembly, and the second magnetic group 45 is fixedly connected to the first transmission member 42 or the second transmission member 43. Specifically, in the embodiment in which the driving member 41 is connected to the first transmission member 42, the second magnetic group 45 is fixedly connected to the first transmission member 42; in the embodiment in which the driving member 41 is connected to the second transmission member 43, the second magnetic group 45 is fixedly connected to the second transmission member 43, as shown in the schematic diagram of the present application. The first magnetic group 44 and the second magnetic group 45 transmit the driving force of the driving member 41 without contact, that is, there is no need to set a connecting member (such as a spline, a flat key, a coupling, etc.) between the driving member 41 and the first transmission member 42 or the second transmission member 43, and the first transmission member 43 can be driven to rotate by the magnetic force; by turning off the magnetism of the first magnetic induction group and the second magnetic induction group, the driving member 41 can be disassembled and assembled, which is convenient for the later inspection and maintenance of the driving member 41. Moreover, this contactless transmission achieved by magnetic force ensures the integrity of the outer wall of the material box 10, and there is no need to set up other transmission structures, thereby improving the convenience of cleaning the material box 10.

[0059] In some embodiments, reference Figure 3 , the material box 10 also has a guide part 13 for guiding the powder to the discharge port 12. One end of the guide part 13 is connected to the inner wall of the material box 10, and the other end extends obliquely to the discharge port 12. As can be seen from the above, the powder in the material chamber 11 falls to the discharge port 12 under the action of gravity, so the bottom of the material chamber 11 is closed to achieve "material guidance", that is, the guide part 13 located at the bottom of the material chamber 11 to connect the discharge port 12 has a slope inclined along the lower right and / or lower left, and the powder automatically falls to the discharge port 12 under the action of the gravity component extending along the slope, thereby achieving material guidance. It should be noted that the present application does not limit the specific structure of the guide part 13. The guide part 13 may include a slope inclined along the lower left or lower right, or two slopes extending in a direction close to each other may be set at the same time. As long as the guide part 13 can guide the powder to the discharge port 12, it will be sufficient.

[0060] Figure 5 This is a front view of the powder device in the first embodiment of the present application, wherein: Figure 5 The stirring assembly 3 and the driving assembly 4 are omitted, and the material box 10 is shown in half section. Figure 6 The top view of the material box 10 is shown, and the material outlet 12 is Figure 6 The position enclosed by the dotted frame is referenced Figure 5 and Figure 6 , the guide portion 13 is inclined along the lower left slope. In some embodiments, refer to Figure 5 The included angle between the guide portion 13 and the first direction is greater than or equal to 30 degrees and less than or equal to 80 degrees. The first direction is Figure 5 In the N1 direction shown, Figure 5 From the perspective, the first direction N1 points to the downward direction in the vertical direction. As can be seen from the above, the powder has a gravity component extending along the slope of the guide portion 13. Figure 5 In some embodiments shown, the angle between the guide portion 13 and the first direction N1 is θ, that is, 30°≤θ≤80°. The embodiment of the present application limits the angle θ between the guide portion 13 and the first direction N1 to ensure that the powder falls fully while maintaining a moderate falling speed.

[0061] In some embodiments, reference Figure 3 and Figure 4 The pushing assembly 2 includes a pushing screw 21, and each pitch of the pushing screw 21 can form an empty space 211 for accommodating powder. A feeding channel 141 is provided in the material box 10, and the pushing screw 21 is arranged in the feeding channel 141, and feeds along the extension direction of the feeding channel 141. Compared with the pushing assembly 2 being set as other structures, such as the pushing assembly 2 can be a linear feeding mechanism driven intermittently by a cylinder, the present application adopts a pushing screw 21 to push the material, and the pushing screw 21 is driven to rotate, so that the empty space 211 with powder can push the powder forward, and then the next empty space 211 moves to the position connected to the discharge port 12 and receives the powder from the discharge port 12, without reserving reset time like a linear feeding mechanism, so that the pushing assembly 2 in the present application has a higher feeding efficiency.

[0062] It should be noted that the present application does not limit the specific structure of the push screw 21. The push screw 21 can be set as a shaftless screw as shown in the schematic diagram of the present application, or it can be set as a shafted screw, as long as the push screw 21 can feed materials in a spiral manner.

[0063] One end of the feeding channel 141 in the axial direction forms a push port 142, and the push screw 21 pushes out the powder in the feeding channel 141 through the push port 142. The material box 10 also has a discharge port 17 connected to the feeding channel 141, and the discharge port 17 is connected to the external environment outside the powder device. The above-mentioned discharge port 12 is connected to the radial direction of the feeding channel 141, that is, the powder in the material chamber 11 first falls to the discharge port 12 under the action of gravity, and enters the empty space 211 of the push screw 21, and then, the driving member 41 drives the push screw 21 to rotate, and the push screw 21 rotates spirally, so that the powder in the feeding channel 141 is sent out through the push port 142, and finally, the powder is discharged from the powder device through the discharge port 17.

[0064] It should be noted that the present application does not limit the specific position and size of the discharge port 17. The discharge port 17 can be opened in the vertical direction as shown in the schematic diagram of the present application, and the powder discharged through the push port 142 falls to the discharge port 17 under the action of gravity. Of course, the discharge port 17 can also be opened along the extension direction of the feeding channel 141, so that the discharge end of the push screw 21 passes through the discharge port 17, and the powder can be directly discharged out of the powder device through the push screw 21; when the discharge port 17 is opened along the extension direction of the feeding channel 141, the push port 142 can be equivalent to the discharge port 17. The size of the discharge port 17 is related to the single powder addition amount of the powder device and the rotation speed of the push screw 21, and the user can set it according to actual needs.

[0065] In some embodiments, reference Figure 4 , the pitch P of the push screw 21 is greater than or equal to 3mm and less than or equal to 12mm. As can be seen from the above, a space 211 for accommodating powder can be formed between each pitch of the push screw 21. Therefore, by limiting the pitch of the push screw 21, the length and depth of the space 211 can be limited, thereby limiting the feeding amount of the push assembly 2 for one rotation, and then limiting the discharge amount of the powder device per unit time (the time required for the push screw 21 to rotate one circle). If the pitch P of the push screw 21 is too large, it is easy for the powder device to add excessive powder per unit time, affecting the discharge accuracy of the powder device; if the pitch P of the push screw 21 is too small, it is easy for the push screw 21 to rotate multiple times before the seasoning added to the powder device meets the cooking taste requirements, affecting the discharge efficiency of the powder device. In the embodiment of the present application, the pitch P of the push screw 21 is limited to a range of greater than or equal to 3 mm and less than or equal to 12 mm, so that the powder device can add powder in an appropriate amount while maintaining powder addition efficiency.

[0066] In some embodiments, reference Figure 5 , the distance L from the discharge port 12 to the push port 142 is greater than or equal to the two pitches of the push screw 21, that is, L≥2P. The position between the discharge port 12 and the push port 142 can be regarded as a "standby position", and the empty spaces 211 located in this position are all pre-stored with powder, and the push screw 21 is driven to rotate, and the push screw 21 can directly push the pre-stored powder to the outside of the powder device. Therefore, under the premise of meeting the site restrictions and the size restrictions of the powder device, the larger the distance L from the discharge port 12 to the push port 142, the more empty spaces 211 located in this position, the more powder pre-stored in the powder device, and the more powder that can be added to the powder device at a single time. The present application stipulates that the distance from the discharge port 12 to the push port 142 is at least greater than the two pitches of the push screw 21, so that there are at least two empty spaces 211 between the discharge port 12 and the push port 142, which can meet at least two powder additions, maintain moderate discharge of the powder device, and be compatible with the seasoning addition efficiency of the powder device.

[0067] Reference Figure 5 , the feeding channel 141 extends along the second direction. Figure 5 The direction of the arrow N2 shown is the second direction N2, and the second direction N2 is in the horizontal direction. It should be noted that the aforementioned "horizontal" is a relative level for the surface to be placed of the powder device. The surface to be placed can be a desktop, a kitchen cabinet, a floor or a workbench. It can be understood that the above-mentioned surface to be placed is generally a horizontal plane, that is, in the first embodiment, the pusher assembly 2 feeds along a direction (second direction N2) on the horizontal plane. Of course, there may be concave and convex in some areas of the above-mentioned surface to be placed, that is, the horizontal plane is not required to be absolutely horizontal, and the existence of the horizontality error of the desktop, kitchen cabinet, floor or workbench is allowed. The embodiment of the present application is provided with a feeding channel 141 extending in the horizontal direction, so that the pusher assembly 2 feeds in the horizontal direction, and the material receiving position of the feeding channel 141 is not on the same vertical line as the discharging position, and the powder in the material box 10 cannot be directly discharged from the powder device due to gravity or vibration. The required amount of powder added is controlled by the movement stroke of the pusher assembly 2 in the horizontal direction, which is convenient for accurate discharging.

[0068] Figure 7 This is a right side view of the powder adding device in the second embodiment of the present application. Figure 7 The stirring assembly 3 and the driving assembly 4 are also omitted. Figure 7 The feeding channel 141 extends along a third direction, wherein the third direction N3 is inclined relative to the second direction N2, that is, the pushing assembly 2 arranged in the feeding channel 141 feeds materials at an inclination relative to the horizontal direction. Figure 7 The direction of the arrow N3 shown in the figure indicates the third direction N3. It can be understood that the third direction is Figure 7 In the upward tilted direction in the viewing angle, that is, in the feeding channel 141, the height of the discharge end (the right end where the push port 142 is located) is greater than the height of the feed end (the left end where the discharge port 12 is located), so even if the material box 10 is vibrated or accidentally touched, the powder in the feeding channel 141 will not be automatically discharged, reducing the risk of excessive discharge of the powder in the feeding channel 141 due to vibration. That is, this tilted design can ensure the accuracy of each powder addition and avoid the problem of poor feeding accuracy caused by accidental falling of powder.

[0069] It should be noted that the present application does not limit the method for realizing the inclined extension of the feeding channel 141. For example, a pad is provided at the bottom of the material box 10, so that the feeding channel 141 extends obliquely relative to the horizontal direction. In this embodiment, the plane where the material box 10 contacts the receiving placement surface (the bottom surface of the material box 10) extends along the third direction N3. Of course, the material box 10 can also be processed into an irregular shape, so that the height of the material box 10 is different (high at the right end and low at the left end), and the feeding channel 141 can also be extended obliquely, such as Figure 7 As shown, in this embodiment, the bottom surface of the material box 10 is a plane extending in the horizontal direction.

[0070] In some embodiments, reference Figure 8 The material box 10 comprises a box body 101 and a base 102. The box body 101 is used to contain powder materials, and the box body 101 is installed on the base 102. The material containing cavity 11 is opened in the box body 101, and the material pushing assembly 2 is connected to the box body 101.

[0071] Specifically, in order to be suitable for cooking a variety of dishes, the box body 101 can be provided with a plurality of material containing chambers 11 to simultaneously contain a variety of condiments. Figure 8 In the third embodiment of the powder device shown, the box body 101 is provided with three material cavities 11, so that three kinds of condiments can be accommodated at the same time. In this embodiment, a plurality of material pushing components 2 and stirring components 3 are provided on one box body 101. Of course, in the case where only one material cavities 11 is provided on one box body 101, a plurality of box bodies 101 can be provided on the base 102 at the same time, so that a plurality of condiments can still be stored. There is no limit on the number of material cavities 11 provided on the box body 101 and the number of box bodies 101 that can be installed on the base 102, and the user can set them according to actual needs.

[0072] Continue to refer to Figure 8 The box body 101 is provided with a first connection structure 15, and the base 102 is provided with a second connection structure 16. The first connection structure 15 and the second connection structure 16 are connected in cooperation, so that the first connection structure 15 is connected to or separated from the second connection structure 16, so that the material box 10 can be installed and removed, which is convenient for cleaning the material box 10. On the other hand, when replacing powder (such as replacing pepper with white sugar), there is no need to pour out the current powder (pepper), only need to disassemble the material box 10 containing the current powder (pepper), and install the powder (white sugar) to be replaced on the second connection structure 16.

[0073] It should be noted that the present application does not limit the specific structure of the first connecting structure 15 and the second connecting structure 16, as long as the first connecting structure 15 can be detachably connected to the second connecting structure 16, such as a matching slide groove and slide tongue structure, or a pin and socket structure, or a magnetic structure, or a snap-on structure, etc.

[0074] In this application Figure 8 In some embodiments shown, the first connection structure 15 is a slide groove, and the second connection structure 16 is a sliding tongue, and the sliding tongue is movably inserted in the slide groove. Compared with the above-mentioned implementation mode in which the first connection structure 15 and the second connection structure 16 are set as other forms, the processing difficulty of the slide groove and the sliding tongue structure is lower, and it is easy to process and shape. In addition, there are no moving parts in the slide groove and the sliding tongue structure, and the assembly is less and it is more convenient to achieve sealing, which reduces the risk of oil entering between the first connection structure 15 and the second connection structure 16, and is convenient to keep the surface of the first connection structure 15 and the second connection structure 16 clean.

[0075] The embodiment of the present application also provides a cooking machine, which includes a frame, a cooking device and the above-mentioned powder device, the cooking device is used to cook dishes, and the cooking device is connected to the frame. The powder device is arranged on the frame adjacent to the cooking device, and the powder device is used to add seasonings to the cooking device to automatically add seasonings during the cooking process of the dishes. It should be noted that a cooking device can be equipped with one or more powder devices to adapt to the cooking of multiple ingredients.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
