Description

Technical Field

[0001] This utility model relates to the field of kettle technology, and in particular to a kettle with a non-contact water level detection structure. Background Technology

[0002] Traditional kettles typically use contact sensors for water level detection, such as float switches or electrode probes. These sensors require direct contact with the liquid and are susceptible to scale and corrosion over time, leading to decreased sensitivity or malfunction. Furthermore, built-in sensors increase structural complexity, affecting cleaning and maintenance. While non-contact detection technologies (such as capacitive sensors) have been explored in recent years, current capacitive water level sensors only function properly when mounted on the outer wall of transparent containers. With metal containers, the metal interferes with the capacitance of the capacitive sensor, resulting in inaccurate water level sensing. Therefore, contact sensors remain the preferred method. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please see Figures 1-5 A kettle with a non-contact water level detection structure is characterized by comprising a kettle body 1 and a water storage chamber 11 opened inside the kettle body 1. A through hole 13 is opened on the outer wall of the kettle body 1, and a sealing element 12 is provided in the through hole 13 to prevent water leakage. A capacitive water level sensor 2 is provided on the sealing element 12. A power base 5 is provided at the bottom of the kettle body 1. The through hole and the sealing element prevent the capacitive water level sensor from being interfered with by the metal container when detecting the water level, thus avoiding inaccurate water level detection by the capacitive water level sensor.

[0019] In some embodiments: the kettle body 1 is made of metal, and the capacitive water level sensor 2 includes a conductive element 21 that acts as an electrode. When water enters the water storage chamber 11, the water passes through the conductive element 21, and the capacitance value of the conductive element 21 changes. The conductive element 21 can then transmit the changed capacitance value to the electronic board of the power base 5 to determine the water level in the water storage chamber 11. As a further explanation and not a limitation, there can be two sealing elements 12 and two conductive elements 21. The two sealing elements 12 are located at the top and bottom of the outer wall of the kettle body 1, respectively, while the two conductive elements 21 are located at the top and bottom of the two sealing elements 12, respectively, so that one conductive element 21 is at a high position and the other is at a low position, thereby detecting the highest and lowest water levels in the water storage chamber 11, so as to prevent the kettle body 1 from dry-boiling due to low water or overflowing due to high water.

[0020] In some embodiments, a handle 3 is provided on the outside of the kettle body 1, and the seal 12 and the capacitive water level sensor 2 are both located between the kettle body 1 and the handle 3. When the seal 12 and the water level sensor 2 are located between the handle 3, the handle 3 will hide the seal 12 and the water level sensor 2 after installation, thus improving the aesthetics of the kettle body 1.

[0021] In some embodiments: the kettle body 1 is provided with a heating base 4, the heating base 4 includes a heating element 41 for heating the kettle body 1, the heating base 4 is provided with a coupler 43 inside the heating base 4, the water inlet pipe 42 is located in the coupler 43, the output end of the coupler 43 is electrically connected to the input end of the heating element 41, the coupler 43 is responsible for forming an electrical connection with the power base 5, when the coupler 43 is powered on, the heating element 41 will start to heat up, thereby allowing the kettle body 1 to start to heat up, thereby heating the water in the water storage chamber 11.

[0022] In some embodiments, the heating base 4 includes a water inlet pipe 42, the outlet of which is located in the water storage chamber 11. The location of the outlet of the water inlet pipe 42 inside the water storage chamber 11 can effectively prevent dust from entering the water inlet pipe 42 and thus avoid affecting the water quality.

[0023] In some embodiments, the sealing element 12 includes a waterproof plug 121, the shape of which matches the through hole 13. One end of the conductive element 21 is located on the waterproof plug 121. The waterproof plug 121 can be made of silicone material, which can prevent the conductive element 21 from coming into direct contact with water and also prevent scale from forming on the waterproof plug 121 when it is in contact with water for a long time.

[0024] Example 2: The difference between this embodiment and Embodiment 1 is that, as Figures 6 to 8 The sealing element 12 includes a water guide pipe 122, both ends of which are connected to the inner wall of the water storage chamber 11. A conductive element 21 is disposed on the water guide pipe 122. The conductive element 21 is used to sense the water level in the water guide pipe 122. When water enters the water storage chamber 11, some water will enter the water guide pipe 122. At this time, when the water level in the water storage chamber 11 starts to rise, the water level in the water guide pipe 122 will also rise along with the water level in the water storage chamber 11. In this way, the water level in the water guide pipe 122 will submerge the conductive element 21, causing the capacitance value of the conductive element 21 to change, thereby enabling the detection of the water level. Furthermore, because the conductive element 21 is located in the water guide pipe 122, it will not come into direct contact with the water, which can effectively avoid the problem of scale formation on the conductive element 21. As a further explanation and not a limitation, the two conductive elements 21 can be located at the high and low points of the water guide pipe 122 respectively to detect the highest and lowest water levels in the water storage chamber 11.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
