For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0033] Reference Figures 1 to 3 According to the first embodiment of the utility model, the rapid heat exchange device includes a shell 100, a container 200, a spiral structure 300 and a driving device 400. The shell 100 has a first cavity, a first interface 110 and a second interface 120. The container 200 is arranged in the first cavity. The container 200 can divide the first cavity into a accommodating cavity 210 and a heat exchange cavity 130. The accommodating cavity 210 is located in the container 200, and the heat exchange cavity 130 is located between the shell 100 and the container 200. The spiral structure 300 is arranged in the shell 100 or the container 200. The spiral structure 300 is located in the heat exchange cavity 130. The spiral structure 300 can divide the heat exchange cavity 130 into a spiral channel. One end of the spiral channel is connected to the first interface 110, and the other end is connected to the second interface 120. The driving device 400 is arranged in the shell 100, and the driving device 400 is connected to the first interface 110. The driving device 400 can drive the heat exchange medium to flow along the spiral channel. The heat exchange chamber 130 can be divided into a spiral channel through the spiral structure 300, and the driving device 400 can drive the heat exchange medium to flow in the spiral channel, and then discharge the heat from the second interface 120. The heat exchange medium can flow fully around the container 200 through the spiral channel, and then can fully take away the heat of the container 200, thereby improving the heat exchange efficiency, accelerating the cooling speed, reducing the waiting time, and facilitating user use.
[0034] Specifically, the first cavity of the shell 100 can be set to open upward, and the container 200 can also be set to open upward. The container 200 is placed from the opening of the shell 100 to separate the first cavity. The container 200 has a accommodating cavity 210. The gap between the container 200 and the shell 100 is a heat exchange cavity 130. The container 200 is used to hold water. It can be understood that a heating device can heat the container 200. A spiral structure 300 can be set on the inner wall of the shell 100. The spiral structure 300 divides the heat exchange cavity 130 into a spiral channel. The spiral channel surrounds the container 100. The container 200 is spirally arranged, and a driving device 400 is connected to the first interface 110 at one end of the spiral channel. The driving device 400 can drive the heat exchange medium to flow in the spiral channel. The specific type of the heat exchange medium is not specifically limited here, and it only needs to be able to exchange heat with the container 200. The specific structure of the driving device 400 is not specifically limited here. The heat exchange medium can flow out at the second interface 120 and take out the heat. Through the above structure, it can quickly exchange heat with the container 200, and then quickly cool the high-temperature hot water to a suitable temperature to facilitate users to brew milk powder.
[0035] It should be noted that the spiral structure 300 is not limited to the above-mentioned embodiment, and other embodiments may also be adopted. For example, the spiral structure 300 may also be arranged on the outer wall of the container 200 .
[0036] Reference Figure 1 to Figure 2 In some embodiments of the present invention, the driving device 400 is configured as a fan. Specifically, the driving device 400 can be configured as a fan, and the fan can be a turbine fan, which can continuously drive wind to circulate in the spiral channel, thereby taking away the heat of the container 200.
[0037] It is understandable that the driving device 400 can also be set as a water pump, which can be connected to an external water source and can pump cooling water to circulate in the spiral channel. The second interface 120 is used for drainage and can also achieve a rapid heat exchange effect.
[0038] Reference Figures 2 to 3 In some embodiments of the present invention, the spiral structure 300 includes a spiral partition plate 310, which is disposed on the inner wall of the housing 100 and spirally disposed around the container 200. The container 200 and the housing 100 cooperate to form a spiral channel, and the structure is relatively simple.
[0039] Specifically, the spiral partition plate 310 is spiral-shaped, and the inner wall of the shell 100 can be set to a cylindrical shape, so that the spiral partition plate 310 can be set on the inner wall of the shell 100. When the container 200 is placed in, the spiral partition plate 310 can cooperate with the container 200 to form a spiral channel, and the structure is simple.

[0042] Specifically, the spiral channel is arranged to rise in a spiral, and the first interface 110 is arranged at the lower part. In cooperation with the driving device 400, it can drive the heat exchange medium to flow from bottom to top to the second interface 120 for discharge, which can fully exchange heat and improve the heat exchange efficiency. Moreover, the hot gas can be discharged upward from the upper second interface 120 without affecting the air intake of the lower first interface 110.

It can facilitate the flow of heat exchange medium, reduce fluid resistance, increase flow rate, and thus improve heat exchange efficiency.
[0044] Specifically, the first pipe 140 and the second pipe 150 can be an integrated structure with the shell 100. The first pipe 140 and the second pipe 150 both extend from the tangent, which can facilitate the flow of heat exchange medium, reduce fluid resistance, increase flow rate, and thus improve heat exchange efficiency. The opening of the first pipe 140 is the first interface 110, and the opening of the second pipe 150 is the second interface 120.
[0045] Reference Figure 1 to Figure 2 In some embodiments of the present invention, the first pipe 140 and the second pipe 150 are extended toward the same side, so that the first interface 110 and the second interface 120 can be arranged on the same side, which is convenient for the arrangement of the driving device 400 and has a more reasonable layout.

Under the premise of not affecting the normal use of the user, it can facilitate heat dissipation and exhaust.
[0048] Specifically, the front of the body 500 can be set as a water outlet, and the user needs to operate at the front of the machine, and the through hole 510 set on the rear side wall can be used for exhausting the air inlet box. The driving device 400, the first interface 110 and the second interface 120 are set at the rear of the milk frother, which can facilitate heat dissipation and exhaust without affecting the normal use of the user.
