As shown in fig. 1 to 4, a liquid heating apparatus 100 according to an embodiment of the present utility model is shown.
As shown in fig. 1, the liquid heating apparatus 100 includes: the water tank 10, the heating body 20 connected with the water tank 10, the temperature sensor 30 connected with the heating body 20, the water outlet head 40 connected with the heating body 20, and the control board 50 respectively electrically connected with the heating body 20 and the temperature sensor 30. Wherein the water tank 10 is used for storing a liquid to be heated. The heating body 20 serves to heat the liquid output from the water tank 10. The temperature sensor 30 is used to detect the temperature of the liquid in the heating body 20. The water outlet head 40 is used for discharging the heated liquid. The control board 50 is used to control the operation of the heating body 20 and to receive feedback data of the temperature sensor 30.
Hereinafter, the above-described liquid heating apparatus 100 will be further described with reference to fig. 1 to 4.
As shown in fig. 2 to 4, a water outlet 11 is provided at a central position of the bottom of the water tank 10. And the bottom of the water tank 10 is also provided with a plurality of water blocking walls 12 which are uniformly distributed circumferentially by taking the water outlet 11 as the center. Water passing holes 121 are arranged between two adjacent water blocking walls 12. The sum of the sectional areas of the water passing holes 121 is not greater than the area of the water outlet 11.
Preferably, as shown in fig. 3, in the present embodiment, the water blocking walls 12 together form a barrier structure arranged in a central symmetry manner centering on the water outlet 11. The water blocking walls 12 together form the barrier structure which is arranged in a central symmetry way, so that the residual liquid at the bottom of the water tank 10 can uniformly flow into the water outlet 11 from all directions when water is lacked, and the monitoring accuracy is improved.
For example, in the present embodiment, the water blocking walls 12 are arc-shaped, the number of the water blocking walls 12 is four, and are distributed at 90 ° intervals, and accordingly, there are four water passing holes 121 in total. The four water blocking walls 12 together form a circular barrier structure.
In other embodiments, each of the water blocking walls 12 is detachably provided at the bottom of the water tank 10 for cleaning maintenance. The detachably arranged water blocking wall 12 is convenient for cleaning and maintenance in later period. For example, a clamping groove surrounding the water outlet 11 may be formed in the bottom of the water tank 10, and the water blocking wall 12 may be clamped in the clamping groove.
As shown in fig. 1, the liquid inlet of the heating body 20 is communicated with the water outlet 11.
In order to achieve the detection of the temperature of the liquid in the heating body 20, the temperature sensor 30 may be mounted in various ways. For example, in the present embodiment, as shown in fig. 1, the temperature sensor 30 is installed on the outer side wall of the heating body 20 in a manner that is direct and rapid for the detection of the temperature of the liquid, and that can avoid the interference of moisture generated in the inner cavity of the heating body 20 due to the heating of the liquid.

When the liquid level in the water tank 10 drops to the water blocking wall 12, the control board 50 monitors that the temperature rising rate of the temperature value fed back by the temperature sensor 30 exceeds the preset fluctuation range, and determines that the liquid level in the water tank 10 drops to the preset warning value. In this embodiment, although the signal processing of the control board 50 is referred to, software or algorithm applied thereto is a conventional means in the art. The improvement point of the scheme is that the water tank 10 is subjected to hardware modification, and then the control board 50 and the temperature sensor 30 which are also provided by the traditional liquid heating device are matched, so that the warning function of the water level of the water tank 10 is realized on the premise of canceling the traditional liquid level detection mechanism.
Furthermore, in other embodiments, the liquid heating apparatus 100 may further include: a signal light and/or a buzzer connected to the control board 50. When the liquid level of the water tank 10 drops to the warning value, a light and/or sound signal which is easily perceived by the user is emitted through a signal lamp and/or a buzzer, so that the user can timely replenish the liquid of the water tank 10.
In order to facilitate control of the liquid input amount of the heating body 20, as shown in fig. 1, in the present embodiment, the liquid heating apparatus 100 further includes: a water pump 60 connected between the water tank 10 and the heating body 20. The water pump 60 is electrically connected to the control board 50. It should be noted that, the water pump 60 is not in conflict with the water blocking wall 12, and the purpose and function of the water pump are different.
The working principle is briefly described:
as shown in fig. 2 and 3, a water blocking wall 12 is provided at the bottom of the water tank 10 around the water outlet 11, and water holes 121 through which liquid can pass are provided between two adjacent water blocking walls 12. As shown in fig. 1, when the liquid level in the water tank 10 decreases to a preset warning value, the height of the liquid level falls within the interception range of the water blocking wall 12, at this time, the liquid located at the periphery of the water blocking wall 12 can only enter the inner side of the water blocking wall 12 and enter the water outlet 11 through the water passing hole 121, at this time, the liquid discharge amount of the water outlet 11 decreases, so that the amount of liquid flowing into the heating body 20 decreases, the temperature detected by the temperature sensor 30 rapidly increases under the condition that the power of the heating body 20 is unchanged, and when the temperature rising rate detected by the control board 50 exceeds the preset fluctuation range, the water tank 10 can be determined to be in a liquid shortage state.
The above-mentioned liquid heating apparatus 100 changes the structure of the water tank 10, and utilizes the temperature sensor 30 and the control board 50 to realize the water shortage warning to the liquid level of the water tank 10, only need to change the water tank 10 in a small extent on hardware, simple structure, with low costs, and the later stage clean maintenance's degree of difficulty is low moreover.
