The liquid may include hot water, which may include boiled water at 100 ℃, or hot water higher than a set temperature, which may be understood as a water temperature required by a user.

It can be appreciated that the cooling medium 311 may include a phase change energy storage material, where the cooling medium 311 may have a certain fluidity, or may be a solid, where the phase change energy storage material has a high latent heat, and the phase change energy storage material with a large thermal conductivity is selected as much as possible, so that the cooling medium can absorb heat of the liquid in the cooling section 420, and the liquid can be cooled to a desired suitable temperature. The cooling medium 311 may further include water, which has good fluidity and strong thermal conductivity, so that the cooling medium 311 can fully absorb heat, and is nontoxic and harmless, simple to obtain and low in cost.

It can be understood that when the volume of the kettle body 200 is larger and the volume of the liquid storage cavity 210 is larger, the weight of the liquid storage cavity 210 filled with liquid is large, and the kettle body 200 is not convenient to move, so that the liquid storage cavity 210, the cooling device 300 and the liquid outlet pipe 400 are integrated in the kettle body 200, which is beneficial to discharging liquid of the kettle body 200 in a fixed state, and improves the convenience of use of users.

Referring to fig. 6 or 7, the cooling device 300 is disposed in the kettle body 200, and is located at a side of the liquid storage cavity 210, an inlet of the liquid transfer section 410 is located below the liquid storage cavity 210 and is communicated with the liquid storage cavity 210, an outlet of the liquid transfer section 410 is connected with the pump body 110, the other end of the pump body 110 is connected with an inlet of the cooling section 420, a step-shaped bulge is disposed above the kettle body 200, a liquid outlet 220 is disposed on a convex lower wall surface, and the cooling section 420 extends from bottom to top until the outlet is communicated with the liquid outlet 220.

It can be understood that the pump body 110 is disposed on the liquid outlet pipe 400 inside the kettle body 200, so as to control the liquid in the liquid storage cavity 210 of the kettle body 200 to flow to the liquid outlet 220 of the kettle body 200, and exchange heat with the cooling medium 311 when passing through the cooling section 420 during the flowing process, so as to realize the cooling effect of the liquid.

According to one embodiment of the present utility model, the pipetting segment 410 is disposed on the base 100 and the cooling device 300 is detachably connected to the base 100. Namely, the outlet of the liquid transferring section 410 is detachably connected with the inlet of the cooling section 420, namely, when the liquid transferring section 410 is connected with the cooling section 420, the kettle body 200, the base 100 and the cooling device 300 form a whole, the whole internal liquid storage cavity 210 and the liquid outlet pipe 400 are communicated, and liquid can directly enter the cooling device 300 for cooling through the liquid transferring section 410 after heating in the kettle body 200, so that the integrated structure is reduced, the whole structure of the liquid heating device is compact, and the portability of the whole device can be ensured while low-temperature liquid is obtained; when the pipetting segment 410 is separated from the cooling segment 420, the cooling device 300 can be detached from the base 100, and the cooling device 300 can be independently arranged, so that the replaceability of the cooling device 300 is improved, and the maintenance cost of the liquid heating device is reduced.

In this embodiment, the detachable connection is an on-off switch plug connection, and in other embodiments, a magnetic connection may be also used, so that the cooling device 300 can be detached from the base 100 and the communication between the pipetting segment 410 and the cooling segment 420 can be realized.

According to one embodiment of the utility model, the cooling section 420 is at least partially a helical coil 424, the helical coil 424 being helically formed about a predetermined axis.

As shown in fig. 1 and 2, the cooling section 420 includes a spiral coil 424 wound along a predetermined longitudinal axis, and the cooling section 420 is spirally wound, so that the length of the cooling section 420 is increased, the flow path of the liquid is lengthened, the heat exchange time is prolonged, and the cooling effect of the cooling device 300 is ensured. The cooling sections 420 extend from top to bottom, and it is understood that the cooling sections 420 are wound clockwise or counterclockwise from top to bottom, and the rotation direction of the cooling sections 420 is approximately horizontal, so that no residual liquid exists compared with the vertical winding mode. When the cooling device 300 is connected to the base 100, the inner moving section 410 in the base 100 is communicated with the cooling section 420 in the cooling device 300, and liquid enters the cooling section 420 from the outlet of the moving section 410 through the inlet of the cooling section 420, moves upwards along the spiral coil 424, and is discharged out of the cooling device 300 through the outlet at the top.

The longitudinal direction may be a vertical direction or a direction forming a certain angle with the vertical direction. That is, the preset axial direction extends longitudinally, and it is understood that the preset axial direction is a vertical line, or a line approaching the vertical direction, which may be slightly leftward (or slightly rightward inclined) with respect to the vertical direction.

Of course, the preset axis may also extend in a transverse direction (not shown), and the spiral coil 424 is wound into a tube extending in a transverse direction, and it is understood that the preset axis is a horizontal line or a line near the horizontal direction, and the near horizontal direction may be slightly downward (or upward) inclined with respect to the horizontal direction. That is, the preset axis is not limited to be completely vertical or completely horizontal, and may form an angle with the vertical direction or the horizontal direction.

For example, the preset axis may have an included angle with the vertical of 30 ° or 45 ° or less. Referring to fig. 1, the included angle between the preset axis and the vertical direction is 0 °, the preset axis is a vertical line, and the cooling section 420 includes a spiral coil 424 which spirals around the preset axis, so that the length of the cooling section 420 in the set height can be increased, and the cooling effect of the cooling device 300 can be optimized.

It is understood that the cooling section 420 may be partially divided into spiral coils 424, and may further have a plurality of spiral coils 424, that is, the cooling section 420 may be provided with a first spiral coil section, then connected with a non-spiral tube section, then connected with a second spiral coil section, and so on, the number of the spiral coils 424 in the cooling section 420 is not limited, so that the contact area between the cooling section 420 and the cooling medium 311 is increased, the flow path of the liquid is lengthened, the heat exchange time is longer, and the cooling effect of the cooling device 300 is ensured.

It will be appreciated that the cooling section 420 may also be in a non-helical form, such as an "S" shaped tube, with the cooling section 420 increasing its length in the cooling chamber 310, lengthening the flow path of the liquid and allowing for a longer heat exchange time.

According to one embodiment of the present utility model, the predetermined axis extends longitudinally and the spiral radius of the spiral coil 424 increases gradually from bottom to top.

As shown in fig. 1 and 2, the cooling section 420 includes a spiral coil 424 wound along a preset longitudinal axis, the spiral coil 424 extends from bottom to top, each time the pipeline of the spiral coil 424 spirals around, the radius of the next spiral layer increases, that is, visually, the spiral coil 424 is arranged in the cooling cavity 310 in a mode of approximately conical top down, it is understood that, by means of the spiral coil 424 formed by increasing the spiral radius layer by layer, the projection area of the spiral coil 424 on the horizontal plane is the collection of the horizontal projection area of the multilayer spiral coil 424, which is far greater than the projection area of the spiral coil 424 formed by adopting the same spiral radius on the horizontal plane, when the liquid flows into the cooling section 420 from the inlet, the cooling medium 311 in the cooling cavity 310 near the inlet heats up, and the cooling medium 311 near the outlet heats up and forms up and down inside the cooling medium 311 unevenly, in the convection process, the larger the projection area of the spiral coil 424 on the horizontal plane is more contacted with the cooling medium 311 in the convection process, the larger the projection area of the spiral coil 424 on the horizontal plane is contacted with the cooling medium 311, and the cooling effect of the cooling device 300 is improved.

It will be appreciated that the spiral coils 424 formed by increasing the spiral radius layer by layer are vertically offset, i.e., when each layer of spiral coils 424 is projected onto a vertical plane, the projected surface of the spiral coils 424 between adjacent layers has an overlapping portion, i.e., the spiral coils 424 formed by increasing the spiral radius layer by layer are smaller in height than the spiral coils 424 formed by using the same spiral radius, thereby reducing the required height of the cooling chamber 310 in which the spiral coils 424 are disposed, and thus reducing the height of the cooling device 300, and the overall structure of the liquid heating apparatus is more compact.

According to one embodiment of the utility model, the cooling section 420 comprises a first rising section 421, a falling section 422 and a second rising section 423, the inlet of the first rising section 421 being in communication with the outlet of the pipetting section 410; the inlet of the falling section 422 communicates with the outlet of the first rising section 421; the inlet of the second rising section 423 communicates with the outlet of the falling section 422.

The cooling section 420 includes a first rising section 421, a falling section 422 and a second rising section 423 which are sequentially communicated, an inlet of the cooling section 420 is positioned at a lower end of the first rising section 421, an inlet of the cooling section 420 is communicated with an outlet of the pipetting section 410 for feeding liquid, and the liquid enters the falling section 422 from an upper end of the first rising section 421 and flows upward in the first rising section 421 and then flows out from an upper end of the first rising section 421.
