[0021] See also Figures 1 to 9 A liquid stirring and heating device includes a main unit 100, a container 200, a stirring unit 300 and a heating unit 400. A clamping groove 110 for connecting the container 200 is opened at the top of the main unit 100. The heating unit 400 is arranged in the clamping groove 110, and the stirring unit 300 is arranged in the main unit 100. The container 200 has a heat conductive sheet 500 matched with the heating unit 400, and a stirring member 600 matched with the stirring unit 300 is arranged inside the container 100. When the container 200 is installed in the clamping groove 110 of the main unit 100, the heating unit 400 contacts the heat conductive sheet 500 to transfer heat, thereby heating the liquid in the container 200, and the stirring unit 300 drives the stirring member 600 to operate to stir the liquid in the container 200.

[0022] Specifically, the container 200 in this embodiment has a heat conductive sheet 500, and a stirring piece 600 is arranged inside the container 200, and a stirring unit 300 cooperating with the stirring piece 600 is arranged inside the main unit 100, and a clamping groove 110 for connecting the container 200 is provided on the top of the main unit 100, and a heating unit 400 cooperating with the heat conductive sheet 500 is arranged in the clamping groove 110. When heating the liquid in the container 200 (such as milk, breast milk, cow's milk, goat's milk, etc.) 10 is in contact with the heating unit 400, so that the heat conducting sheet 500 is heated by the heating unit 400, and then the heat conducting sheet 500 conducts heat to the liquid in the container 200, so as to achieve heating of the liquid in the container 200. In order to avoid local overheating of the liquid in the container 200, the stirring unit 300 can be operated to drive the stirring member 600 in the container 200 to operate. When the stirring member 600 is in operation, it will stir the liquid in the container 200, so as to achieve stirring and heating of the liquid in the container 200 at the same time, so as to ensure that the liquid in the container 200 can be heated evenly and avoid sintering into agglomerates.

[0023] The container 200 in this embodiment includes a container body 210 and a container cover 220. The container cover 220 is sealed with the container body 210 to facilitate the container 200 to store liquid. In addition, in order to ensure that the heat conductive sheet 500 of the container 200 can more conveniently cooperate and contact with the heating unit 400 in the snap-in groove 110, the heat conductive sheet 500 is located on the container cover 220. The top cover of the container cover 220 is the heat conductive sheet 500, which is made of stainless steel. This material can prevent the top cover of the container cover 220 from rusting, and can be easily cleaned, and has good thermal conductivity. Of course, the material of the heat conductive sheet 500 is not limited to this, and other heat conductive materials can also be used.

[0024] In addition, in order to facilitate the installation of the container 200 and the host 100, the clamping slot 110 in this embodiment has a limiting portion 111, and the limiting portion 111 includes a fixed limiting portion 111 and a movable limiting portion 111, and the fixed limiting portion 111 and the movable limiting portion 111 are arranged diagonally, and the side of the container cover 220 is provided with a clamping portion 221. When the container 200 and the host 100 are installed and matched, the movable limiting portion 111 is opened to the outside direction, and then the container 200 is directly installed in the clamping slot 111 of the host 100. 1, and the clamping portion 221 on one side of the container cover is first inserted into the fixed limiting portion 111, and then the movable limiting portion 111 is reset, so that the clamping portion 221 on the other side of the container cover 220 is clamped into the movable limiting portion 111, so that the installation and removal between the container 200 and the host 100 are more convenient and simple through the cooperation of the diagonally arranged limiting portion 111 and the clamping portion 221, and the specific structure of the limiting portion 111 and the clamping portion 221 can be referred to Chinese patent: CN220158098U, so it is not repeated here.

[0025] See also Figure 4 and Figure 5 In this embodiment, in order to heat the liquid in the container 200, the heating unit 400 includes a flexible heating sheet 410, a soft rubber layer 420 and a substrate 430. The substrate 430, the soft rubber layer 420 and the flexible heating sheet 410 are stacked in sequence in the clamping groove 110 from bottom to top, and the substrate 430 is provided with a through hole 431, and an elastic member 440 is provided in the through hole 431. One end of the elastic member 440 abuts against the soft rubber layer 420, and the other end abuts against the bottom of the clamping groove 110.

[0026] Among them, the substrate 430 is made of hard material, so it can well support the soft rubber layer 420 and the flexible heating sheet 410, and the flexible heating sheet 410 is used for heating, and it can adopt a circular structure and be made of KAPTON electric heating film, which can better cooperate with the container cover 220, but the structure and material of the flexible heating sheet 410 are not limited to this. Its specific structure can refer to the Chinese patent: CN220158098U. In addition, the soft rubber layer 420 can be made of silicone material, which can be made of silicone material with a hardness of 5-25 degrees.

[0027] In the initial state, the soft glue layer 420 and the flexible heating sheet 410 will protrude upwards. When fixed, the side of the soft glue layer 420 is connected to the substrate 430 by bonding. The flexible heating sheet 410 is directly fixed on the soft glue layer 420. A through hole 431 is provided in the middle of the substrate 430, and an elastic member 440 with one end abutting against the soft glue layer 420 is provided in the through hole 431. Therefore, the elastic force of the elastic member 440 can make the soft glue layer 420 and the flexible heating sheet 410 protrude upwards. When the liquid in the container 200 is heated, the container 200 is directly installed in the card slot 110 of the host 100. At this time, the heat conductive sheet 500 of the container cover 220 will come into contact with the flexible heating sheet 410, and the elastic force of the elastic member 440 can make the flexible heating sheet 410 closely come into contact with the heat conductive sheet 500, avoiding the phenomenon of poor heating effect caused by poor contact, thereby ensuring that the heating unit 400 heats the liquid in the container 200 more effectively.

[0028] See also Figure 2 , Figures 6 to 9 In order to stir the liquid in the container 200, the stirring unit 300 includes a driving member 310 and a magnetic member 320. The magnetic member 320 is arranged at the output end of the driving member 310, and a plurality of magnetic members 320 can be arranged. The driving member 310 can drive the magnetic member 320 to perform linear motion, and the stirring member 600 includes an integrally formed fixing portion 610, a deformation portion 620 and a stirring portion 630. The two ends of the deformation portion 620 are respectively connected to the fixing portion 610 and the stirring portion 630. The fixing portion 610 is pressed between the container body 210 and the container cover 220, and a plurality of flow holes 640 are respectively opened on the deformation portion 620 and the stirring portion 630, and the stirring portion 630 is also wrapped with a power member 650.

[0029] In this embodiment, the driving member 310 can adopt a push-pull electromagnet (solenoid) or other driving structures. It is only necessary to make the magnetic member 320 perform telescopic movement inside the main unit 100, and the magnetic member 320 is a magnet. At the same time, the power member 650 wrapped by the stirring part 630 can also be a magnet or a metal member that can be magnetized. For example, when the power member 650 is a magnet, the magnetic member 320 and the power member 650 are in a state of mutual magnetic attraction, and the overall thickness of the heating unit 400 and the bottom of the card slot 110 is 8mm-10mm, so it will not affect the magnetic attraction between the two.

[0030] Specifically, when stirring, the container 200 containing liquid (breast milk, breast milk, milk, etc.) is directly installed with its container cover 220 into the clamping slot 111 of the host 100, and the stirring unit 300 is started. The driving member 310 of the stirring unit 300 drives the magnetic member 320 to move in a straight line, so that the magnetic member 320 extends forward. At this time, the power member 650 wrapped by the stirring part 630 in the stirring member 600 will be attracted to the magnetic member 320 due to the magnetic attraction principle, so that the stirring part 630 moves. When the stirring part 630 moves, the deformation part 620 will be deformed. When the driving member 310 retracts and resets the magnetic member 320 backward, The power part 650 is disconnected from the magnetic part 320, and the stirring part 630 is reset by the elastic force of the deformation part 620 itself, so as to realize the reciprocating operation of the deformation part 620 and the stirring part 630. The deformation part 620 and the stirring part 630 reciprocate inside the container 200, and through the flow holes 640 on the deformation part 620 and the stirring part 630, the liquid inside the container 200 can be stirred up and down ('breathing' and beating), and then combined with the heating unit 400 to heat the liquid inside the container 200, finally realizing simultaneous heating and stirring, so as to ensure that the liquid in the container 200 can be heated evenly to avoid sintering into agglomerates.

[0031] When the container 200 and the host 100 are connected, the container cover 220 is installed in the snap-in groove 110. Therefore, the container 200 is in an inverted state, and the stirring member 600 is fixed between the container cover 220 and the container body 210. Therefore, at this time, the stirring member 600 is at the bottom of the liquid in the container 200. When the driving member 310 drives the magnetic member 320 to make a linear motion, the stirring member 600 moves up and down to stir the liquid in the container 200. The up and down beating and stirring of the stirring member 600 and the setting of the stirring member 600 at the bottom of the liquid can prevent the liquid from generating foam when being stirred, thereby ensuring the safety of drinking for infants and preventing infants and young children from vomiting milk.

[0032] Of course, in order to ensure that the deformation portion 620 of the agitator 600 can generate elasticity, the agitator 600 in this embodiment is integrally formed using silicone material, which can facilitate the production of the agitator 600 while providing sufficient elasticity. The silicone material has good safety performance and can ensure the safety of infants and young children.

[0033] Furthermore, in this embodiment, the fixing portion 610 of the agitator 600 made of silicone material is pressed between the container body 210 and the container cover 220, which can effectively seal the container cover 220 and the container body 210, thereby eliminating the need for additional sealing components, thereby simplifying components and reducing costs.

[0034] In another embodiment, the agitator 600 can also directly adopt a magnet or a magnetically attracted metal part and place it directly in the container 200. When the agitator 600 adopts this configuration, the driving part 310 of the agitator unit 300 is a rotating motor, and the rotating motor drives the agitator 600 to rotate.

[0035] Specifically, when stirring the liquid in the container 200, the container 200 is inverted so that the container cover 220 of the container 200 is installed in the snap-in groove 110. When the container 200 is inverted, the stirring member 600 will fall on the container cover 220 and be magnetically attracted to the magnetic member 320 of the stirring unit 300. At this time, the rotating motor drives the magnetic member 320 to rotate, and the magnetic member 320 drives the stirring member 600 inside the container 200 to rotate when rotating. The rotation of the stirring member 600 stirs the liquid inside the container 200, thereby achieving heating and stirring of the liquid in the container 200, ensuring that the liquid in the container 200 can be evenly heated to avoid sintering into agglomerates.

[0036] Since the liquid in the container 200 is stirred in a rotating manner, foam will be generated. Therefore, it is necessary to first evacuate the container 200 (negative pressure). Vacuuming can effectively avoid the generation of foam. Therefore, the liquid stirring and heating device also includes a vacuum unit 700. The vacuum unit 700 includes a vacuum pump 710 and a one-way valve nozzle 720 arranged on the container cover 220. The vacuum pump 710 is connected to the one-way valve nozzle 720 to achieve vacuuming of the interior of the container 200.

[0037] During the setting, the vacuum pump 710 can be a separate component. When the liquid in the container 200 is stirred in a rotating manner, half or more of the liquid is filled in the container 200, so that the container 200 retains a certain amount of residual space, and then the separate vacuum pump 710 is connected to the one-way valve nozzle 720 on the container cover 220, so that the inside of the container 200 can be evacuated. Of course, the vacuum pump 710 can also be directly set in the host 100, and through holes can be set at the card slot 110 and the heating unit 400 to facilitate the docking of the vacuum pump 710 and the one-way valve nozzle 720. When evacuating the vacuum, the container cover 220 of the container 200 is installed on the host 1 00, and the one-way valve nozzle 720 passes through the heating unit 400 and the through hole at the bottom of the clamping groove 110 to dock with the vacuum pump 710 inside the host 100, and then the host 100 and the container 200 are turned over as a whole, so that the container 200 is located at the bottom and the host 100 is located at the top, so as to achieve vacuuming the inside of the container 200. After the vacuuming is completed, the host 100 and the container 200 are turned over as a whole, so that the host 100 is located at the bottom and the container 200 is located at the top, and finally the liquid inside is stirred and heated by the heating unit 400 and the stirring unit 300, so that the container 200 can be operated reasonably during vacuuming.

[0038] In addition, when the driving member 310 adopts a rotating motor and the stirring member 600 adopts a magnet or a magnetically attractable metal member, this structure can also be used in a milk making machine. Specifically, a proper amount of milk powder and liquid is poured into the container 200, and the rotation speed of the driving member 310 is adjusted and set (the rotation speed is increased). The driving member 310 drives the stirring member 600 to rotate rapidly in the container 200, thereby achieving rapid and uniform mixing of the milk powder and the liquid, thereby achieving the purpose of brewing milk powder.

[0039] Since milk making machines and milk shaking machines on the market will produce foam when making milk powder, in this embodiment, before making milk powder, the container 200 can be evacuated by the vacuum unit 700. By evacuating, the interior of the container 200 is placed in a vacuum (negative pressure) state. At this time, the driving member 310 drives the stirring member 600 to rotate rapidly to stir and mix the liquid and milk powder, thereby preventing the stirring member 600 from producing foam when stirring the liquid, thereby preventing infants from vomiting milk when sucking, and improving the safety of infants' sucking.

[0040] When in use, the vacuum unit 700 can be used in combination with warming milk, shaking milk, mixing milk, and stirring milk. By using the combination, the generation of foam can be avoided. In addition, the vacuum unit 700 can also be used alone. For example, after pouring an appropriate amount of prepared breast milk, goat milk, cow's milk, milk (milk powder brewing), etc. into the container 200, the container 200 can be directly vacuumed through the vacuum unit 700. Through the vacuum method, the breast milk, goat milk, cow's milk, milk (milk powder brewing), etc. in the container 200 can also be avoided from generating tiny bubbles (fine bubbles), thereby achieving the defoaming function by vacuuming the container 200.

[0041] By evacuating the container 200, the interior of the container 200 can be placed in a vacuum (negative pressure) state. In the vacuum (negative pressure) state, the boiling temperature of the internal liquid is extremely reduced, thereby accelerating the heating speed of the liquid in the container 200. At the same time, by evacuating the container 200, when the liquid in the container 200 is stirred in a rotating manner, the generation of foam can be effectively avoided, thereby ensuring the safe drinking of infants and preventing infants from vomiting milk. In addition, the bacteria in the container 200 can be effectively reduced by evacuating the container (negative pressure), thereby facilitating the storage of the liquid in the container 200 and thereby increasing the storage time of the liquid in the container.

[0042] Finally, in order to control the heating unit 400 and the stirring unit 300, in the present embodiment, a circuit board and a power supply unit (not shown in the figure) are further provided inside the main unit 100, wherein the circuit board is electrically connected to the heating unit 400, the stirring unit 300 and the power supply unit, respectively, the power supply unit can provide electrical energy to the stirring unit 300, the heating unit 400, etc., and the circuit board can control the stirring unit 300 and the heating unit 400. In addition, when the vacuum unit 700 is provided in the main unit 100, it can also be electrically connected to the circuit board, and the vacuum unit 700 is controlled by the circuit board to achieve vacuuming of the container 200.
