Description

TECHNICAL FIELD

[0001] The utility model relates to the field of electric kettle, especially a electric teapot with detecting water level. BACKGROUND

[0002] At present, the electric kettle monitors the highest and lowest water level mainly by installing an inductive probe in the kettle, and the highest and lowest water level lines are sensed by the protruding inductive probe to avoid water overflow and dry burning. There is no good quantitative monitoring of the highest and lowest water level process. If the inductive probe is damaged, dry burning and water overflow will easily occur. In addition, the installation of the protruding water level inductive probe in the kettle is a big defect in product cleanliness and appearance.

[0003] Of course, the prior art also has an electric teapot that detects water level by pressure. However, the actual teapot has a predetermined stroke, which can easily cause damage to the product or inaccurate measurement data during transportation. INVENTION CONTENTS

[0004] The main purpose of the utility model is to provide an electric teapot with detecting water level, which aims to improve the water level detection method of the existing electric teapot. Although the upper weighing disc has a displacement interval, the actual measurement is obtained by deformation, not the stroke amount as in the prior art.

[0005] To achieve the above purpose, the utility model provides an electric teapot with detecting water level, which comprises:

[0006] The base is a shell provided with a containing cavity. The upper wall of the shell is provided with a positioning groove in communication with the containing cavity.

[0007] The lower weighing disc is installed on the top wall of the containing cavity. A spacing is provided between the lower weighing disc and the bottom wall of the shell.

[0008] The upper wall of the lower weighing disc is provided with a pressure sensor.

[0009] The upper weighing disc is provided on the upper wall of the pressure sensor and is in close contact with the pressure sensor.

[0010] The lower end of the support frame is connected with the upper weighing disc. The upper part of the support frame protrudes out of the positioning groove. The middle part of the support frame is provided with a first electric connector. The kettle is provided with a second electric connector matched with the first electric connector.

[0011] When the kettle is not placed, the pressure sensor obtains the initial pressure value of the upper weighing disc and the support frame.

[0012] When the kettle is placed, the pressure sensor obtains the first pressure value of the kettle.

[0013] When the kettle is filled with water, the pressure sensor obtains the water level change in the kettle according to the pressure value to obtain a second pressure value.

[0014] In actual design, the data of the kettle (whether the water filling instruction is triggered) can be accurately obtained through the pressure sensor.

[0015] When the kettle is placed, the pressure sensor obtains the pressure value of the kettle, thereby avoiding dry burning caused by heating, and when the water filling is started, the water filling amount in the kettle can be accurately obtained through the pressure value change of the pressure sensor (i.e. the change pressure value - the first pressure value, i.e. the current water level pressure value).

[0016] The water amount in the kettle can be accurately obtained.

[0017] The setting of the lower weighing disc can avoid sensor failure or damage caused by liquid in the base.

[0018] The pressure value of the pressure sensor and the water level change can adopt the prior art, or a maximum value is set according to the pressure value change, for example, when the pressure value is 10, the water level is at the full position.

[0019] When the pressure value is 2, the water level can prevent dry burning.

[0020] The switching between the pressure value and the water level value is realized. BRIEF DESCRIPTION OF DRAWINGS
