[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-5 A water bath heating device in this embodiment includes a water bath box 1, a partition 2, a heating rod 3, a water inlet pipe 4, a water outlet pipe 5 and a placement tube 6. The side of the partition 2 is fixedly installed on the inner wall of the water bath box 1, and the placement tube 6 is arranged inside the partition 2 and is movably connected with the partition 2. Six through holes are opened inside the partition 2, and the number of placement tubes 6 is several and corresponds to the number of through holes, and they are respectively located inside the through holes. The heating rod 3 is arranged inside the water bath box 1 (and the connecting head of the heating rod 3 passes through and extends to the outside of the placement tube 6). The heating rod 3 is serpentine, which increases the contact area between the heating rod 3 and the heating medium, so that the heating medium heats up faster and more evenly. The water inlet pipe 4 is connected to the left side of the water bath box 1, and a water pump is fixedly installed at one end of the water inlet pipe 4 away from the water bath box 1. The water pump can be used to pump the heating medium into the water bath box 1. The water outlet pipe 5 is connected to the bottom of the water bath box 1.

[0031] By placing the heated dishes into the placement cylinder 6, the heating medium is introduced into the water bath box 1 by using the water pump connected to the water inlet pipe 4, and the heating rod 3 is powered on for heating to heat the dishes in the placement cylinder 6. If the required heating temperature exceeds one hundred degrees Celsius according to actual use, the water can be replaced with other media with higher boiling points. After the medium is drained through the water outlet pipe 5, the medium with higher boiling point can be added into the water bath box 1 for heating.

[0032] Among them, an adjusting ring is fixedly connected to the surface of the placing cylinder 6 and is located above the partition 2. The surface of the adjusting ring is provided with anti-slip grooves. The anti-slip grooves play an anti-slip role and are convenient for driving the placing cylinder 6 to rotate through the adjusting ring. A retaining ring is fixedly connected to the surface of the placing cylinder 6 and is located below the partition 2. The surface of the retaining ring is fitted with the bottom of the partition 2. The retaining ring can be used to limit the placing cylinder 6 to prevent the placing cylinder 6 from moving up and down during rotation.

[0033] A lifting assembly 7 is arranged between the bottom of the placing cylinder 6 and the bottom of the water bath box 1. The lifting assembly 7 is used to adjust the height of the internal container of the placing cylinder 6. The lifting assembly 7 includes a connecting ring 701, a lifting rod 702, a lifting plate 703, a limiting plate 704, a limiting groove 705 and a slider 706. The connecting ring 701 is fixedly installed at the bottom of the placing cylinder 6, and the inner wall is provided with a thread. The surface of the lifting rod 702 is provided with a thread (not shown in the figure), which is threadedly connected to the inner wall of the connecting ring 701. The bottom of the lifting plate 703 is fixedly connected to the top of the lifting rod 702, and the lifting rod 702 is located at At the center of the lifting plate 703, the interior of the lifting plate 703 is hollowed out, and the lifting plate 703 is circular. The center of the lifting plate 703 is located on the same straight line as the center of the placement tube 6. The lifting plate 703 is hollowed out with multiple holes, which is convenient for the bottom of the container to contact the heating medium for heat exchange. The limiting plate 704 is fixedly connected to the inner bottom wall of the water bath box body 1 and is perpendicular to the inner bottom wall of the water bath box body 1. The limiting groove 705 is opened on the side of the limiting plate 704 close to the lifting rod 702. The slider 706 is fixedly connected to the surface of the lifting rod 702, and the slider 706 is located inside the limiting groove 705.

[0034] By rotating the adjusting ring on the placing cylinder 6, the placing cylinder 6 is driven to rotate, and the placing cylinder 6 drives the connecting ring 701 to rotate. The connecting ring 701 is threadedly connected to the lifting rod 702. Since the slider 706 connected to the lifting rod 702 is located inside the limiting groove 705, it limits the lifting rod 702, so that the lifting rod 702 moves up and down, and the lifting rod 702 drives the lifting plate 703 to move. The vessel is placed on the lifting plate 703. When the height of the vessel is low, the vessel can be lifted upward to prevent the medium from flowing into the interior of the vessel, and to facilitate the vessel to be taken.

[0035] The working principle of the above embodiment is:

[0036] When the height of the vessel is too low, it needs to be adjusted. By rotating the adjusting ring on the placement tube 6, the connecting ring 701 is fixedly connected to the placement tube 6, so the placement tube 6 drives the connecting ring 701 to rotate. Since the connecting ring 701 is threadedly connected to the surface of the lifting rod 702, the limiting groove 705 is used to limit the lifting rod 702, so that the lifting rod 702 moves up and down, and the lifting rod 702 drives the lifting plate 703 to move. The vessel is placed on the lifting plate 703. When the height of the vessel is low, the vessel can be lifted upward to prevent the medium from flowing into the interior of the vessel, and it is convenient to take the vessel. The water pump connected to the water inlet pipe 4 is used to introduce the heating medium into the water bath box 1, and the heating rod 3 is powered on for heating to heat the vessel in the placement tube 6. When the heating temperature required by the actual use exceeds one hundred degrees Celsius, the medium can be drained by the water outlet pipe 5, and a medium with a higher boiling point can be added to the water bath box 1 for heating to meet different heating needs.
