Technical Field

[0001] This utility model relates to the field of home appliance technology, and in particular to a vacuum heating and stirring device. Background Technology

[0002] When feeding infants, they often need to finish the milk, breast milk, or formula in several feedings due to burping, crying, playing, etc., which takes a long time each time. As a result, the milk, breast milk, or formula in the container will cool down, which can easily cause diarrhea when fed to the infant. In response to the above problems, various bottle warmers, formula makers, and bottle shakers have appeared on the market, such as the Chinese patent that the applicant has been granted: 2024213327326.

[0003] However, the stirring and heating device in the aforementioned patent requires the container to be inverted and connected to the device when heating and stirring milk, breast milk, or cow's milk in the container. If the user operates improperly or the container's seal is not good during connection, the milk, breast milk, or cow's milk in the container will spill or drip out, causing considerable inconvenience and waste. Furthermore, because the container needs to be inverted for connection, this type of stirring and heating device is inconvenient to use, not conducive to operation, and lacks practicality. In view of this, a new stirring and heating device needs to be designed to improve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum heating and stirring device with a reasonable structural design, convenient and simple operation, and the ability to avoid the generation of foam and caking.

[0005] To solve the above technical problems, the present invention can be implemented using the following technical solutions:

[0006] A vacuum heating and stirring device includes a main body, a vacuum unit, and a heating and stirring unit. The vacuum unit is disposed inside the main body, and the heating and stirring unit is inserted into the main body. Under the action of external force, the heating and stirring unit can extend and retract along one end of the main body. The end of the main body for the extension and retraction of the heating and stirring unit is also fitted with a soft rubber part, and a vacuum suction hole communicating with the vacuum unit is opened on the soft rubber part. When the device is in use, the soft rubber part seals the opening of the container, the vacuum unit evacuates the inside of the container, and the heating and stirring unit extends under the action of suction force and is placed in the liquid inside the container to stir and heat the liquid inside the container.

[0007] In one embodiment, the vacuum unit includes a vacuum pump, a multi-port connector, and a vacuum relief valve. The multi-port connector has an air inlet at the bottom and an air outlet and a pressure relief port at the top. The air inlet is connected to the vacuum suction port of the soft rubber part, the vacuum pump is connected to the air outlet of the multi-port connector, and the vacuum relief valve is connected to the pressure relief port of the multi-port connector.

[0008] In one embodiment, a detection hole is also provided on one side of the multi-port connector, and a vacuum sensor is connected to the detection hole.

[0009] In one embodiment, the soft rubber part is provided with a liquid storage tank, which is located between the vacuum suction hole and the air inlet hole.

[0010] In one embodiment, the heating and stirring unit includes a heat-conducting rod, a heating module, and a stirring module. The heat-conducting rod is cylindrical and a fixing member is inserted inside the heat-conducting rod. The heating module and the stirring module are respectively installed in conjunction with the fixing member, and the heating module contacts the heat-conducting rod to transfer heat.

[0011] In one embodiment, the heating module includes a wire and a heating element, the wire passing through the fixing member and being electrically connected at one end to the heating element, which is in close contact with the inner wall of the heat-conducting rod.

[0012] In one embodiment, the stirring module includes a driving component, a rotating component, and a stirring component. The driving component is mounted on a fixed component and has a gear at its output end. The rotating component is rotatably sleeved on the fixed component and has a driven tooth that meshes with the gear at its upper end and a magnetic component at its lower end. The stirring component is sleeved on a heat-conducting rod and has a magnetic suction component corresponding to the magnetic component on its stirring component.

[0013] In one embodiment, the agitator has a plurality of agitating blades distributed on it.

[0014] In one embodiment, the soft part is made of food-grade silicone.

[0015] In one embodiment, the main body is further provided with an electronic control unit and a power supply unit, the electronic control unit being electrically connected to the vacuum unit, the heating and stirring unit and the power supply unit respectively. Beneficial effects

[0016] In use, this vacuum heating and stirring device involves aligning the main body with the opening of the container. After alignment, a soft rubber part seals the opening. Once sealed, the vacuum unit activates to create a vacuum inside the container. This vacuuming generates suction, which extends the heating and stirring unit into the liquid inside the container. The heating and stirring unit then simultaneously stirs and heats the liquid. This design is rational and easy to operate. The container does not need to be inverted, thus avoiding the risk of leakage or spillage. It also ensures uniform heating of the liquid, preventing caking. Furthermore, the pre-vacuuming process prevents foaming during stirring, facilitating drinking and nutrient absorption for infants. Attached Figure Description

[0033] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0034] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] Please see Figures 1 to 3A vacuum heating and stirring device includes a main body 100, a vacuum unit 200, and a heating and stirring unit 300. The vacuum unit 200 is disposed inside the main body 100, and the heating and stirring unit 300 is inserted into the main body 100. Under the action of external force, the heating and stirring unit 300 can extend and retract along one end of the main body 100. A soft rubber part 400 is also sleeved on the end of the main body 100 for the extension and retraction of the heating and stirring unit 300, and a vacuum suction hole 410 communicating with the vacuum unit 200 is opened on the soft rubber part 400. When the device is in use, the soft rubber part 400 seals the opening of the container, the vacuum unit 200 evacuates the inside of the container, and the heating and stirring unit 300 extends under the action of suction force and is placed in the liquid inside the container to stir and heat the liquid inside the container.

[0037] Specifically, in this embodiment, when using the device, a liquid (such as milk powder, breast milk, cow's milk, goat's milk, etc.) is placed in the container, and the main body 100 is aligned with the opening of the container. After alignment, the soft rubber part 400 at the lower end of the main body 100 seals the opening of the container, and the lower end of the heating and stirring unit 300 is placed inside the container. At this time, the vacuum unit 200 is activated, and the vacuum unit 200 evacuates the container through the vacuum suction hole 410 of the soft rubber part 400. Since a certain suction force is generated during vacuuming, the heating and stirring unit 300 is driven to extend downwards, so that the lower end of the heating and stirring unit 300... The end is inserted into the liquid in the container. Once the container is evacuated to a set vacuum state, the heating and stirring unit 300 is activated, heating and stirring the liquid in the container simultaneously. This ensures that the liquid in the container is heated evenly, preventing sintering and clumping. Furthermore, by evacuating the container in advance, a vacuum state is created inside the container, preventing foaming during stirring, which is convenient for infants to drink and absorb nutrients. In addition, since the device does not require inverting the container during use, it avoids liquid spillage or leakage due to improper operation or poor sealing. This makes the overall structure of the device reasonable and easy to operate.

[0038] In addition, the soft rubber part 400 in this embodiment is made of food-grade silicone. The soft rubber part 400 can ensure the sealing of the container opening, so that the vacuum unit 200 can evacuate the inside of the container. At the same time, by setting the soft rubber part 400 at the lower end of the main body 100, the device can be matched and sealed with containers with openings of different sizes, thereby improving the compatibility and practicality of the device.

[0039] In order to control the vacuuming unit 200 and the heating and stirring unit 300, in this embodiment, the main body 100 is also provided with an electronic control unit 500 and a power supply unit 600. The electronic control unit 500 is electrically connected to the vacuuming unit 200, the heating and stirring unit 300 and the power supply unit 600 respectively. The electronic control unit 500 can independently control the vacuuming unit 200 and the heating and stirring unit 300, or can control them simultaneously with one button. The power supply unit 600 can supply power to the electronic control unit 500, the vacuuming unit 200 and the heating and stirring unit 300.

[0040] When the vacuum unit 200 is controlled independently, it can be used in conjunction with warming milk, shaking milk, preparing milk, stirring milk, etc. By using them in combination, foam can be removed. For example, first pour an appropriate amount of prepared breast milk, goat milk, cow milk, milk (milk powder preparation), etc. into the container, and then use the vacuum unit 200 to vacuum the container. By vacuuming, the generation of tiny foams (fine foam) in the breast milk, goat milk, cow milk, milk (milk powder preparation), etc. in the container can be avoided, and the defoaming function can be achieved by vacuuming.

[0041] Furthermore, by evacuating the container, the interior of the container can be placed in a vacuum (negative pressure) state. In a vacuum (negative pressure) state, the boiling temperature of the liquid inside the container is drastically reduced, thereby accelerating the heating rate of the liquid inside the container.

[0042] Please see Figures 3 to 5 In order to achieve vacuuming inside the container, the vacuuming unit 200 in this embodiment includes a vacuum pump 210, a multi-port connector 220 and a vacuum relief valve 230. An air inlet 221 is provided at the bottom end of the multi-port connector 220, and an air outlet 222 and a pressure relief hole 223 are provided at the top end. The air inlet 221 is connected to the vacuum suction hole 410 of the soft rubber part 400, the vacuum pump 210 is connected to the air outlet 222 of the multi-port connector 220, and the vacuum relief valve 230 is connected to the pressure relief hole 223 of the multi-port connector 220.

[0043] The inlet 221, outlet 222, and pressure relief port 223 on the multi-port connector 220 are all interconnected. When vacuuming, the vacuum relief valve 230 closes the pressure relief port 223. At this time, the vacuum pump 210 at the outlet 222 can perform vacuuming. In order to ensure the vacuuming effect, the vacuum pump 210 is a multi-stage series vacuum pump (two stages in this embodiment). Therefore, the gas in the container will be extracted by the vacuum suction port 410, outlet 222, and vacuum pump 210 to make the container reach the set vacuum state. This facilitates the heating and stirring unit 300 to heat and stir the liquid in the container, thereby avoiding foaming when stirring the liquid and preventing infants from spitting up when sucking, thus improving the safety of infants sucking. In addition, by vacuuming (negative pressure), bacteria in the container can also be effectively reduced, which facilitates the storage of the liquid in the container and increases the storage time of the liquid in the container.

[0044] After the liquid in the container (such as milk powder, breast milk, cow milk, goat milk, etc.) is heated and stirred under vacuum, the pressure in the container can be released through the pressure relief hole 223 and the vacuum pressure relief valve 230, so as to facilitate the separation of the soft rubber part 400 at the lower end of the main body 100 from the opening of the container, thereby separating the device from the container. The vacuum pressure relief valve 230 makes the design of the device reasonable and easy to operate.

[0045] Meanwhile, a detection hole 224 is provided on one side of the multi-port connector 220. The detection hole 224 is connected to a vacuum sensor 240. The vacuum sensor 240 can monitor the state during vacuuming in real time so that the vacuum state inside the container reaches the set requirement and ensures the vacuuming effect inside the container.

[0046] For further details, please refer to Figure 3 The soft rubber part 400 is also provided with a liquid storage tank 420, which is located between the vacuum suction hole 410 and the air inlet 221. During vacuuming, the container is already half or more filled with liquid (such as milk powder, breast milk, cow's milk, goat's milk, etc.). When the vacuuming unit 200 evacuates the container, it may suck up some liquid from the container (usually a few drops). The sucked liquid will enter the liquid storage tank 420 along the vacuum suction hole 410 for storage, thereby preventing liquid from being sucked into the vacuuming unit 200 and causing damage, thus improving the protection of the vacuuming unit 200 and extending its service life. After the device is used once, since the soft rubber part 400 is fitted at the lower end of the main body 100, the soft rubber part 400 can be directly removed and the liquid storage tank 420 can be cleaned, thus making the structural design of the device reasonable.

[0047] Please see Figures 6 to 9In order to heat and agitate the liquid in the container, the heating and agitation unit 300 in this embodiment includes a heat-conducting rod 310, a heating module 320 and an agitation module 330. The heat-conducting rod 310 is cylindrical and a fixing member 340 is inserted inside the heat-conducting rod 310. The heating module 320 and the agitation module 330 are respectively installed in cooperation with the fixing member 340, and the heating module 320 contacts the heat-conducting rod 310 to transfer heat.

[0048] The heat-conducting rod 310 is a one-piece cylindrical structure with an opening at its upper end. A fixing member 340 is inserted inside the heat-conducting rod 310, through which the heating module 320 and the stirring module 330 can be installed and fixed. The heat-conducting rod 310 can be made of stainless steel, which makes it less prone to rusting, easy to clean, and has good thermal conductivity. Of course, the material of the heat-conducting rod 310 is not limited to stainless steel and other thermally conductive materials can also be used. In the initial state, the open end of the heat-conducting rod 310 is placed inside the main body 100, and the soft rubber part 400 is fitted onto the outer wall of the heat-conducting rod 310 to facilitate the connection between the heat-conducting rod 310 and the main body 100. The system is sealed. When the vacuum unit 200 evacuates the container, the suction force drives the heat-conducting rod 310 downwards until it reaches the liquid in the container. At this time, the heating module 320 transfers heat to the heat-conducting rod 310, thereby heating the liquid. Simultaneously, the stirring module 330 stirs the liquid in the container, thus achieving simultaneous heating and stirring. This ensures that the liquid in the container is heated evenly, preventing sintering and clumping. Furthermore, the stirring is performed under vacuum, which avoids the formation of foam during stirring. After the device is used, the user can simply push the heat-conducting rod 310 back to its original position.

[0049] In order to conduct heat to the heat-conducting rod 310, the heating module 320 in this embodiment includes a wire 321 and a heating element 322. The wire 321 passes through the fixing member 340 and one end is electrically connected to the heating element 322, which is in close contact with the inner wall of the heat-conducting rod 310. One end of the wire 321 is electrically connected to the electronic control unit 500, and the other end passes through the fixing member 340 and is electrically connected to the heating element 322. The heating element 322 is in close contact with the inner wall of the lower end of the heat-conducting rod 310. The wire 321 conducts electricity to make the heating element 322 heat up, and the heating element 322 then transfers the heat to the heat-conducting rod 310 so that the heat-conducting rod 310 heats the liquid in the container. The heating element 322 can be made of KAPTON electric heating film and has a ring structure, so that it can better fit the inner wall of the heat-conducting rod 310. Of course, the structure and material of the heating element 322 are not limited to this, and other structures and materials can also be used, as long as the heating element 322 can transfer heat to the heat-conducting rod 310.

[0050] Similarly, in order to achieve the stirring function, the stirring module 330 in this embodiment includes a driving component 331, a rotating component 332, and a stirring component 333. The driving component 331 is mounted on the fixing component 340 and has a gear 334 at its output end. The rotating component 332 is rotatably sleeved on the fixing component 340 and has a driven tooth 332a that meshes with the gear 334 at its upper end and a magnetic component 332b embedded at its lower end. The stirring component 333 is sleeved on the heat-conducting rod 310 and has a magnetic suction component 333a corresponding to the magnetic component 332b embedded on the stirring component 333.

[0051] When the heat-conducting rod 310 is inserted into the liquid in the container under the action of suction, the agitator 333 will also be inserted into the liquid. The drive unit 331 will drive the gear 334 to rotate. The drive unit 331 is a motor. Since the gear 334 meshes with the driven tooth 332a of the rotating member 332, it will drive the rotating member 332 to rotate. When the rotating member 332 is rotating, the magnetic element 332b at the lower end of the rotating member 332 is magnetically attracted to the magnetic element 333a of the agitator 333. Therefore, the stirring element 333 can rotate, and when the stirring element 333 rotates, it will stir the liquid in the container, thereby achieving simultaneous stirring and heating of the liquid to ensure that the liquid in the container can be heated evenly and avoid sintering into lumps; the magnetic element 332b can be a magnet, and the magnetic suction element 333a can be a magnet or a magnetically suction metal part, and because the wall thickness of the heat-conducting rod 310 is relatively thin, it will not affect the magnetic attraction between the magnetic element 332b and the magnetic suction element 333a.

[0052] Of course, in order to better agitate the liquid in the container, several agitating blades 333b are also distributed on the agitator 333. When the agitator 333 rotates, the agitating blades 333b can agitate the liquid so that the liquid in the container can be agitated better.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
