[0020] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0021] like Figures 1 to 6As shown, a cosmetic material heating device according to an embodiment of the present invention comprises a tank body 10, on which a heating element 14 is arranged, and an external heating medium enters the heating element 14 along an inlet pipe 15 to heat the tank body and the material inside, and a feed port 11 is arranged on the tank body 10, and a discharge pipe 12 is arranged on the tank body 10, and a support foot 13 is fixedly installed on the tank body 10, and a circulating stirring mechanism 20 is arranged in the tank body 10, and the circulating stirring mechanism 20 comprises an inner cylinder 21 installed inside the tank body 10 through a transposition component 60, and a gear rod 22 is driven by a driving component 40 on the tank body 10, and the driving component 40 comprises a mounting frame 41 fixedly installed on the tank body 10, and a motor 42 is fixedly installed on the mounting frame 41, and a motor 42 is fixedly installed on the output shaft of the motor 42 A belt reel 43 is fixedly installed, and a gear ring 44 threadedly connected to the gear rod 22 is rotatably installed on the mounting frame 41, and the gear ring 44 is transmission-connected to the belt reel 43 through a belt 45. A push plate 23 is fixedly installed on one end of the gear rod 22 located in the tank body 10, and a thread groove 211 is provided on the inner cylinder 21, and the push plate 23 is threadedly connected to the thread groove 211. The push plate 23 is circularly arranged, and its diameter is smaller than that of the inner cylinder 21. A rectangular protrusion is provided on the push plate 23, and a mounting cavity 24 is provided at the rectangular protrusion of the push plate 23, and a stirring member 25 is arranged in the mounting cavity 24; the stirring member 25 includes a first folding rod 251 arranged in the mounting cavity 24, a second folding rod 252 is provided on the first folding rod 251, and an auxiliary stirring rod 253 is provided on the second folding rod 252; The raw materials to be heated are poured into the tank body 10 along the feed inlet 11, and the switch of the heating element 14 is turned on to heat the materials in the tank body 10. Then, the motor 42 is turned on. The motor 42 cooperates with the belt reel 43 and the belt 45 to drive the gear rod 22 to rotate. When the gear rod 22 rotates, the push plate 23 cooperates with the thread groove 211 to perform a rotating downward movement. When the push plate 23 moves, it cooperates with the stirring element 25 to stir the raw materials in the inner cylinder 21 and squeeze the materials downward. The materials under the push plate 23 in the inner cylinder 21 will be squeezed between the inner cylinder 21 and the tank body 10, and as the push plate 23 continues to move, the raw materials between the inner cylinder 21 and the tank body 10 flow into the inner cylinder 21 along the high position in the tank body 10. During the material flow, uniform heating effect is achieved while improving the material stirring and mixing efficiency. When the push plate 23 moves to the lowest point, the motor 42 drives the gear rod 22 to rotate in the opposite direction, driving the push plate 23 to rotate upward. The anti-backflow component 30 on the push plate 23 allows the raw materials to continue to remain in the inner cylinder 21 during the upward movement of the push plate 23. Repeating the above steps can make the material circulate and heat and stir in the tank body 10 and the inner cylinder 21, avoiding the problem of poor heating and stirring and mixing effects of the material at the bottom, resulting in low production efficiency. At the same time, the protrusion on the push plate 23 can stir the material above it during the rotation of the push plate 23, which can further improve the stirring and heating efficiency. The first folding rod 251 and the second folding rod 252 in the stirring member 25 can change shape as the push plate 23 rises and falls under the action of gravity. The first folding rod 251 and the second folding rod 252 in different shapes can stir different areas, thereby improving the stirring of the material and making the heating more uniform. At the same time, the auxiliary stirring rod 253 under the second folding rod 252 can improve the stirring effect of the material at the bottom of the tank body 10.

[0022] A scraper 254 is fixedly mounted on the first folding rod 251; During the folding and deformation of the first folding rod 251, the scraper 254 can scrape the side wall of the installation cavity 24 to scrape out the material, which is convenient for cleaning after stirring and mixing and improves the cleaning efficiency. At the same time, the scraper 254 expands the area of ​​the first folding rod 251 and can improve the effect of the first folding rod 251 during stirring.

[0023] The inner bottom wall corners of the tank body 10 are rounded; the rounded corners can reduce the dead corner area at the bottom of the tank body 10 to improve the effect of circulating heating.

[0024] like Figures 7 to 9As shown, an anti-backflow assembly 30 assembled on the push plate 23, the anti-backflow assembly 30 includes a pair of through holes 31 opened on the push plate 23, two pairs of slide grooves 32 are opened on the push plate 23, and connecting members 33 are slidably installed in the slide grooves 32. A sealing plate 34 that matches the through hole 31 is fixedly installed at one end of the connecting member 33 away from the slide groove 32, and an elastic member 35 is fixedly installed on the connecting member 33, and the other end of the elastic member 35 is fixedly connected to the inner wall of the slide groove 32. When the gear rod 22 drives the push plate 23 to move upward, the raw materials in the inner cylinder 21 will not flow back together with the reset of the push plate 23, so as to realize the cyclic and uniform heating of the materials; During the downward rotation of the push plate 23, the elastic member 35 cooperates with the connecting member 33 to make the sealing plate 34 coincide with the through hole 31, and the material below the push plate 23 will not enter the top of the push plate 23 along the through hole 31. When the push plate 23 rotates upward, the resistance of the material causes the sealing plate 34 to move downward and causes the connecting member 33 to squeeze the elastic member 35. At this time, the material above the push plate can flow along the through hole 31 to the bottom of the push plate 23, which can prevent the material from flowing back between the inner cylinder 21 and the tank body 10. At the same time, since the push plate 23 rotates upward, the material can further improve the mixing and heating efficiency when passing through the rotating through hole 31.

[0025] like Fig.10 As shown, an auxiliary stirring assembly 50 is assembled on the inner cylinder 21, and the auxiliary stirring assembly 50 includes a plurality of movable grooves 51 opened on the inner cylinder 21, and a magnetic movable frame 52 is slidably installed in each of the movable grooves 51, and a pair of stirring blades 53 are rotatably installed in the magnetic movable frame 52. The magnetic movable frame 52 cooperates with the push plate 23, and assists in stirring the material flowing between the inner cylinder 21 and the tank body 10 with the lifting and lowering of the push plate 23, thereby improving the heating effect and strengthening the mixing effect of the material; When the material between the inner cylinder 21 and the tank body 10 flows back to the inner cylinder 21, the material between the inner cylinder 21 and the tank body 10 will pass through the magnetic mounting frame 41, and drive a pair of stirring blades 53 to rotate to stir the material between the inner cylinder 21 and the tank body 10, thereby improving the stirring efficiency. In addition, during the movement of the push plate 23, the magnetic movable frame 52 attracted to it will move with it in the movable groove 51, thereby changing the stirring position, so that the materials on both sides of the inner cylinder 21 can be stirred and heat exchanged, further improving the heating and stirring effects.

[0026] like Fig.11 As shown, a transposition assembly 60 is provided in the tank body 10, and the transposition assembly 60 includes a pair of arc grooves 61 provided on the inner bottom wall of the tank body 10, a support member 62 is slidably installed in the arc groove 61, and the inner cylinder 21 is fixedly installed on the support member 62; When the push plate 23 cooperates with the stirring member 25 to stir the material, the material rotates. The rotating material can enable the inner cylinder 21 to drive the support member 62 to rotate in the arc groove 61. When the inner cylinder 21 rotates, the position of the auxiliary stirring assembly 50 will change, thereby achieving a more efficient heating, stirring and mixing effect.

[0027] Working principle: Pour the raw materials to be heated into the tank body 10 along the feed inlet 11, turn on the switch of the heating element 14 to heat the materials in the tank body 10, and then turn on the motor 42. The motor 42 cooperates with the belt reel 43 and the belt 45 to drive the gear rod 22 to rotate. When the gear rod 22 rotates, the push plate 23 cooperates with the thread groove 211 to make a rotating downward movement. When the push plate 23 moves, it cooperates with the stirring element 25 to stir the raw materials in the inner cylinder 21 and squeeze the materials downward. The materials under the push plate 23 in the inner cylinder 21 will be squeezed between the inner cylinder 21 and the tank body 10, and as the push plate 23 continues to move, the raw materials between the inner cylinder 21 and the tank body 10 flow into the inner cylinder 21 along the high position in the tank body 10. In the process of material flow, uniform heating effect is achieved while improving the efficiency of material stirring and mixing. When the push plate 23 moves to the lowest point, the motor 42 drives the gear rod 22 to rotate in the opposite direction, driving the push plate 23 to rotate upward. The anti-backflow component 30 on the push plate 23 allows the raw materials to continue to remain in the inner cylinder 21 during the upward movement of the push plate 23. Repeating the above steps can make the material circulate and heat and stir in the tank body 10 and the inner cylinder 21, avoiding the problem of poor heating and stirring and mixing effects of the material at the bottom, resulting in low production efficiency. At the same time, the protrusion on the push plate 23 can stir the material above it during the rotation of the push plate 23, which can further improve the stirring and heating efficiency. The first folding rod 251 and the second folding rod 252 in the stirring member 25 can change shape as the push plate 23 rises and falls under the action of gravity. The first folding rod 251 and the second folding rod 252 in different shapes can stir different areas, thereby improving the stirring effect of the material to make the heating more uniform. At the same time, the auxiliary stirring rod 253 below the second folding rod 252 can improve the stirring effect of the material at the bottom of the tank body 10. During the folding and deformation of the first folding rod 251, the scraper 254 can scrape the side wall of the installation cavity 24 to scrape out the material, which is convenient for cleaning after stirring and mixing, and improves the cleaning efficiency. At the same time, the scraper 254 expands the area of ​​the first folding rod 251, which can improve the effect of the first folding rod 251 during stirring; During the downward rotation of the push plate 23, the elastic member 35 cooperates with the connecting member 33 to make the blocking plate 34 coincide with the through hole 31, and the material below the push plate 23 will not enter the upper part of the push plate 23 along the through hole 31. When the push plate 23 rotates upward, the resistance of the material causes the blocking plate 34 to move downward and causes the connecting member 33 to squeeze the elastic member 35. At this time, the material above the push plate can flow along the through hole 31 to the lower part of the push plate 23, which can prevent the material from flowing back between the inner cylinder 21 and the tank body 10. At the same time, since the push plate 23 rotates upward, the material can further improve the mixing and heating efficiency when passing through the rotating through hole 31. When the material between the inner cylinder 21 and the tank body 10 flows back to the inner cylinder 21, the material between the inner cylinder 21 and the tank body 10 will pass through the magnetic mounting frame 41, and drive a pair of stirring blades 53 to rotate to stir the material between the inner cylinder 21 and the tank body 10, thereby improving the stirring efficiency. In addition, during the movement of the push plate 23, the magnetic movable frame 52 attracted to it will move with it in the movable groove 51, thereby changing the stirring position, so that the materials on both sides of the inner cylinder 21 can be stirred and heat exchanged, further improving the heating and stirring effects; When the push plate 23 cooperates with the stirring member 25 to stir the material, the material rotates. The rotating material can enable the inner cylinder 21 to drive the support member 62 to rotate in the arc groove 61. When the inner cylinder 21 rotates, the position of the auxiliary stirring assembly 50 will change, thereby achieving a more efficient heating, stirring and mixing effect.

[0028] The above describes an embodiment of the present invention, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms, all of which are protected by this embodiment.
