[0028] The preferred embodiments of the utility model are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the utility model.

[0029] like Figures 1 to 4As shown, a liquid heater includes a base and a pot body. The pot body is detachably placed on the base. The base includes an upper cover 1 and a bottom shell 8. A temperature measuring component 2 is disposed on the side of the upper cover 1 and is movably connected to the upper cover 1. When the pot body is placed on the base, the temperature measuring component 2 is pressed against the side of the pot body and completely embedded inside the upper cover 1. When the pot body leaves the base, the temperature measuring component 2 partially pops out of the upper cover 1. In this embodiment, the pot body is made of high borosilicate glass. When the pot body is placed on the base, the side of the pot body near the bottom contacts the temperature measuring component 2. Therefore, every time the pot body is placed on the base, the bottom side of the pot body can contact the temperature measuring component 2. In this way, the temperature of the liquid inside the pot body is conducted to the temperature measuring component 2 through the pot body. The temperature measuring component 2 can monitor the temperature of the liquid inside the pot body in real time. Moreover, since the temperature measuring component 2 contacts the pot body near the bottom, it can also measure the temperature of the liquid when the liquid inside the pot body decreases. Therefore, the temperature of the liquid can be monitored accurately and timely.

[0030] The temperature measuring component 2 includes a temperature measuring base 201. A groove 2011 is provided near the upper end of the temperature measuring base 201. The temperature measuring base 201 is connected to the temperature measuring cover 205. A slider 2051 is provided near the upper end of the temperature measuring cover 205. The slider 2051 is slidably connected in the groove 2011. A spring 202 is provided between the temperature measuring base 201 and the temperature measuring cover 205. The spring 202 abuts against the temperature measuring cover 205. When the pot is placed on the base, the bottom of the pot presses the temperature measuring cover 205 towards the temperature measuring base 201. At this time, the spring 202 is compressed. The elastic force of the spring 202 on the temperature measuring cover 205 makes the temperature measuring cover 205 always press against the side wall of the pot, so that the temperature measuring plate 206 can more accurately measure the temperature of the pot and the liquid inside. When the pot is removed, the temperature measuring cover 205 is still ejected from the cover 1 due to the elastic force of the spring 202.

[0031] The temperature measuring base 201 has an inner cover 203 connected to a temperature measuring plate 204. A temperature measuring element 206 is mounted on the upper temperature measuring cover 205 and is electrically connected to the temperature measuring plate 204. The bottom shell 8 houses a main board 6 and a fan 7. A black crystal non-grinding plate 3 is mounted on the inner liner 4, and an electro-ceramic disc 5 is positioned below the black crystal non-grinding plate 3. The temperature measuring plate 204 is electrically connected to the main board 6, so the temperature measured by the temperature measuring element 206 can be transmitted to the main board 6 via an electrical signal. This allows the pre-programmed liquid heater to control the heating time and temperature of the liquid by the electro-ceramic disc 5.

[0032] The bottom shell 8 is connected to the inner liner 4, and the bottom of the bottom shell 8 is connected to the anti-slip foot 801. The inner liner 4 supports the electric ceramic plate 5 and also supports the kettle body. The inner liner 4 makes the internal structure of the base more stable, increases the service life of the base, and also protects the electrical components inside the base from being easily damaged by collisions.

[0033] A control panel 102 is also provided on the top cover 1. The control panel 102 is electrically connected to the main board 6. Users can use the control panel 102 to adjust and control the use of the liquid heater, including but not limited to the heating temperature and time.

[0034] A baffle plate 9 is installed below the temperature measuring component 2. When there is residual water on the black crystal non-grinding plate 3, or when water droplets seep in from the temperature measuring component 2, they will be blocked by the baffle plate 9 and will not enter the interior of the base, thus preventing water from contacting the main board 6 and other components. Therefore, it can play a good protective role for the electrical components inside the base.

[0035] Finally, it should be noted that the above are merely preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the utility model should be included within the protection scope of the utility model.
