Description

Technical Field

[0001] This invention belongs to the technical field of liquid heating devices, specifically relating to a device for rapidly heating packaged liquid beverages such as milk and other beverages. Background Technology

[0002] Our company's sweetened milk for breakfast is loved by families and sells well in the market. In winter, both families and breakfast shops generally need to heat the milk.

[0003] Chinese invention patent CN 111134545 B discloses a rapid heating device for boxed milk. The technical solution involves placing the boxed milk in a storage frame, with a motor driving a rotating disc to rotate, which in turn drives a dial to rotate, which in turn drives the storage frame to rotate. Simultaneously, the hot water in the heating shell also accelerates its flow and reaches the same temperature. Under the heating effect of the flowing hot water, the boxed milk placed in the storage frame can be heated quickly and evenly.

[0004] It can be observed that the above technical solution uses water as the heat medium, and the boxed milk is basically stationary in the storage frame. Even if the external hot water is circulating, the temperature of the center of the box needs to be slowly transferred from the surface, which can only accelerate the heating speed to a certain extent. A better solution would be to allow the liquid inside the boxed milk to slosh around, so that the temperature can be quickly and evenly distributed in the center and on the surface of the box, greatly improving the heating speed.

[0005] On the other hand, using hot water as the heating medium requires a relatively large amount of water, resulting in significant heat loss. The weight of the water also places a heavy load on the rotation, necessitating the use of a motor to assist in rotation. Therefore, the above-mentioned technical solution suffers from two main drawbacks: high operating costs and the need to improve heating speed. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a rapid heating device for liquid beverages. This device uses steam as a heat medium, utilizes steam jets as the rotational power for the storage frame, and incorporates a component that causes the milk to slosh. Its overall structural and functional features overcome the aforementioned shortcomings of the prior art.

[0007] The objective of this invention is achieved through the following technical solution: a rapid heating device for liquid beverages, comprising a cylindrical device body with an opening at the top, and a lid that can seal the opening of the device body; a mounting column extending upward from the bottom center of the device body; the heating device further comprising: a heating element, a steam generator, a tightly rotatable steam drive gear, and a driven gear, all mounted on the mounting column from bottom to top; the steam drive gear is floatingly mounted on the upper end of the steam generator, with a certain gap between the steam drive gear and the driven gear; the upper end of the steam generator is provided with at least one steam outlet, the steam outlet having an inclination with the end face, so that when steam is ejected, it can lift the steam drive gear and, under the action of the inclination, make it rotate along the axis of the mounting column;

[0008] The heating device also includes a rotating frame sleeved on the mounting column and fixedly connected to the driven gear. The rotating frame includes a central seat, multiple support rods rotatably connected to the central seat and extending outward, and a storage frame fixedly connected to the end of each support rod.

[0009] Preferably, the heating element is electric, and a control panel is mounted on the outer surface of the device body. Electric heating is relatively convenient and also makes it easier to control the timer via the control panel.

[0010] Preferably, the upper part of the steam generator is made into a threaded top cover, which is then fitted onto the outer circumference of the mounting column, with the steam outlet located on the top cover. Manufacturing the steam generator as a separate unit makes it easier to process and maintain.

[0011] Preferably, there are three steam outlets, evenly distributed at 120-degree intervals. With three steam outlets, the force injected simultaneously from the three outlets will be more effectively converted into rotational force.

[0012] Preferably, the heating device also includes a water injection assembly, a lower water injection channel provided between the bottom wall and side wall of the top cover, and an upper water injection channel provided in the mounting column. The water injection assembly eliminates concerns about water supply during the use of the heating device, making it safer and more convenient.

[0013] Preferably, the water injection assembly includes a detachable water storage container connected to the inlet of the upper water injection channel, a one-way valve installed in the lower water injection channel, and an annular gate fixed inside the center of the steam-driven gear and extending downward; the side wall of the annular gate is provided with a ring of gate holes; the end side wall of the upper water injection channel has a through hole, the position of which corresponds to the channel inlet of the lower water injection channel; the annular gate is tightly fitted on the outer surface of the upper water injection channel and the side wall of the top cover, and is configured such that when the steam-driven gear is raised, the gate hole is higher than the channel inlet of the lower water injection channel.

[0014] Preferably, the rotating frame is equipped with a swaying generating component, which includes a blocking part fixedly connected to the edge of the upper end face of the central seat and corresponding to the position of each frame rod, an active part fixed on each frame rod and corresponding to the blocking part, a torsion spring sleeved on the outer periphery of the frame rod with one end fixed to the active part and the other end fixed to the frame rod, a fixed gear fixed on the storage frame and located on the side close to the inner wall of the device body, a universal roller fixedly connected to the fixed gear on the same axis, and a toothed belt fixedly connected to the inner wall of the device body. The torsion spring's torque causes the active part to abut against the blocking part, stabilizing the rotation of the frame. When the fixed gear reaches the toothed belt, it slows down upon impact, causing the internal liquid to slosh due to inertia. As it passes through the toothed belt, the storage frame tilts, causing the milk or beverage placed on it to tilt as well, thus mixing the internal liquid. Once it has completely passed through the toothed belt, the torsion spring's torque causes the active part to quickly impact the blocking part, further enhancing the mixing effect of the milk or beverage.

[0015] Preferably, the position corresponding to the omnidirectional roller has a guide groove covering the entire circumference, and the omnidirectional roller falls into the guide groove. The omnidirectional roller falling into the guide groove can increase the stability of the rotation of the frame.

[0016] Preferably, the toothed belt is fixed below the guide groove. Being below the guide groove is more concealed, making it less likely to scratch your hand when picking up milk or beverages.

[0017] Preferably, the fixed gear and toothed belt are made of rubber with a certain degree of elasticity. Rubber can absorb some of the impact cushioning and reduce the noise of the impact.

[0018] In summary, the present invention has the following advantages compared with the prior art:

[0019] This invention uses water as the heating medium, just like existing technologies. However, in existing technologies, water needs to completely cover the outer packaging of milk or beverages, resulting in a large volume of water. In contrast, this invention utilizes the sealed space to boil water into steam, significantly reducing the volume of the heating medium. Consequently, the device can be made lighter and more compact, and the heating speed can be much faster. It also eliminates the need for a power source motor. Furthermore, this invention uses steam jets as the rotational power source for the rotating frame, thus replacing the power source motor. The added shaking component improves the mixing effect inside the liquid, thereby accelerating thermal convection. The steam generator is designed to automatically add water as the internal air pressure decreases, resulting in a safer, more energy-efficient, and faster heating process overall.

Detailed Implementation

[0029] The present invention will be further described below with reference to the embodiments illustrated in the accompanying drawings:

[0030] Example 1

[0031] like Figure 1-7 As shown, a liquid beverage rapid heating device includes a cylindrical device body 1 with an opening at the top, and a lid 2 that can seal the opening of the device body 1.

[0032] A mounting column 11 extends upward from the bottom center of the device body 1. The heating device also includes: a heating element 3, a steam generator 4, a tightly rotatable steam drive gear 5, and a driven gear 6, which are mounted on the mounting column 11 from bottom to top. The heating element 3 and the steam generator 4 are arranged in contact or close to each other. The steam drive gear 5 is floatingly mounted on the upper end of the steam generator 4. There is a certain gap between the steam drive gear 5 and the driven gear 6. The upper end of the steam generator 4 is provided with at least one steam outlet 41. The steam outlet 41 has an inclination with the end face. When steam is ejected, it can lift the steam drive gear 5 and make it rotate along the axis of the mounting column 11 under the action of the inclination.

[0033] The steam-driven gear 5 can be made with multiple concave or convex ridges on the surface where steam is injected, which can generate greater resistance and improve the force conversion effect.

[0034] The heating device also includes a rotating frame 7 sleeved on the mounting column 11 and fixedly connected to the driven gear 6. The rotating frame 7 includes a central seat 71, multiple support rods 72 rotatably connected to the central seat 71 and extending outward, and a storage frame 73 fixedly connected to the end of each support rod 72.

[0035] In this embodiment, the heating element 3 is electrically heated, and a control panel 12 is installed on the outer surface of the device body 1.

[0036] In use, water is injected into the steam generator 4, and the heating element 3 is activated via the control panel 12. The steam generator 4 continuously sprays steam, which is ejected outward from the steam outlet 41. The sprayed steam pushes the steam drive gear 5 upward, meshing with the driven gear 6 and rotating simultaneously. At the same time, the steam trapped inside the device body 1 exchanges heat with the milk or beverage to be heated. The rotation also promotes temperature equalization within the device body. As the water inside gradually decreases, the steam injection is often unstable. Taking advantage of this instability, the rotatable shelf 73 is made to sway intermittently, causing fluctuations inside the milk or beverage to be heated, thereby accelerating heat exchange.

[0037] To facilitate water filling of the steam generator 4, the upper end of the steam generator 4 is made into a threaded top cover 4a. The top cover 4a is fitted around the outer periphery of the mounting column 11. The steam outlet 41 is located on the top cover 4a. In order to make the steam drive gear 5 more evenly lifted, the steam outlet 41 is set in three evenly distributed at 120 degrees to each other.

[0038] To ensure rapid and automatic replenishment of water in the steam generator 4 after evaporation during the heating process, this heating device includes a water injection assembly 8, a lower water injection channel 42 that mates with the bottom and side walls of the top cover 4a, and an upper water injection channel 111 located in the mounting column 11. The water injection assembly 8 includes a detachable water storage container 81 connected to the opening of the upper water injection channel 111, a one-way valve 82 installed in the lower water injection channel 42, and an annular gate 83 fixed to the center of the steam drive gear 5 and extending downwards. The side wall is provided with a ring of gate holes 831; the end side wall of the upper water injection channel 111 has a through hole, the position of which corresponds to the channel inlet of the lower water injection channel 42. The annular gate 83 is tightly fitted on the outer surface of the upper water injection channel 111 and the side wall of the top cover 4a, and is configured such that when the steam-driven gear 5 is raised, the gate hole 831 is higher than the channel inlet of the lower water injection channel 42. In this way, the connection channel between the upper water injection channel 111 and the lower water injection channel 42 will be closed by the annular gate 83 below the gate hole 831, and when the steam-driven gear 5 is raised... After falling back to its original position, the gate hole 831 falls into the connecting channel between the upper water injection channel 111 and the lower water injection channel 42. In this way, the water in the water storage container 81 will rush through the one-way valve 82 and enter the steam generator 4. Although there is always air pressure inside the steam generator 4 during the heating process, even without the gate valve, the water in the water storage container 81 will not easily enter. However, if the air pressure is slightly unstable, that is, if the water pressure is greater than the air pressure for a short period of time, water will enter the steam generator 4, making it impossible for the steam generator 4 to output steam stably. The design of this gate valve requires that the water inside the steam generator 4 be evaporated or the device be shut down, and the steam drive gear 5 loses the steam push and falls down to connect the entire water inlet channel. Water will enter until the steam generator 4 is full. If it is during the heating process, since the water storage container 81 is inside the device body 1, it has a higher base temperature. Therefore, the time to reheat to boiling and generate steam is shorter. If it is after shutdown, the design can also ensure that the steam generator 4 is full of water before each heating.

[0039] To ensure stable rotation of the rotating frame 7 during heating, and to reduce the amplitude of swaying generated by the storage frame 73, a sway generating component 9 is provided in the rotating frame 7. The sway generating component 9 includes a blocking part 91 fixedly connected to the edge of the upper end face of the central seat 71 and corresponding to the position of each support rod 72; an active part 92 fixed to each support rod 72 and corresponding to the blocking part 91; a torsion spring 93 sleeved on the outer circumference of the support rod 72, with one end fixed to the active part 92 and the other end fixed to the support rod 72; a fixed gear 94 fixed to the storage frame 73 and located near the inner wall of the device body 1; and a universal roller 95 coaxially fixedly connected to the fixed gear 94. Under normal conditions, the active part 92 presses against the blocking part 91 under the action of the torsion spring 93. On the inner wall of the device body 1, corresponding to the position of the universal roller 95, there is a guide groove 13 covering the entire circumference. The universal roller 95 falls in the guide groove 13, increasing the stability of the rotation of the rotating frame 7. The shaking generating component 9 also includes a toothed belt 96 fixedly connected below the guide groove 13. When the rotating frame 7 rotates under the action of the steam injection angle, the fixed gear 94 comes to the position of the toothed belt 96. After the two collide, the fixed gear 94 will be forced to rotate. This rotation drives the storage frame 73 to rotate, and the storage frame 73 drives the frame rod 72 to rotate. The torsion spring 93 is then tightened by overcoming the torque. At the same time, the active part 92 moves away from the blocking part 91. The number of teeth of the toothed belt 96 determines the rotation angle of the storage frame 73. This angle controls the milk or beverage inside to prevent it from tipping over and sliding out. When the fixed gear 94 passes the toothed belt 96, the torque of the torsion spring 93 quickly resets the rotating components, thereby generating a shock wave on the milk or beverage and accelerating the convection of heat.

[0040] The materials for the fixed gear 94 and the toothed belt 96 are preferably rubbers with a certain degree of elasticity, so as to reduce the impact sound when touched.

[0041] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
