Detailed Implementation

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] This invention relates to a smart kettle with TDS water quality detection function, such as... Figures 1 to 4 As shown, it includes a kettle body 1 and an electric heating plate assembly 2. The kettle body 1 is used to hold drinking water, and the kettle body 1 is provided with a kettle bottom 11, as shown. Figure 7 As shown, a raised platform 111 is formed in the middle of the bottom 11 of the pot, as... Figure 1 As shown, by forming the recessed platform 111 structure, the bottom of the pot 11 can be made into a three-dimensional disc-shaped structure, which can increase the structural strength and rigidity of the bottom of the pot 11 and prevent the bottom of the pot 11 from easily deforming. Figure 1 and Figure 7 As shown, an annular ridge 112 can also be formed on the outer side of the recessed platform portion 111 of the pot bottom 11. Thus, the recessed platform portion 111 is the relatively sunken part of the pot bottom 11, while the ridge 112 is the relatively convex part of the pot bottom 11. Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the electric heating plate assembly 2 includes an aluminum heat transfer plate 22, which is attached to the underside of the recessed platform 111, which has a flat plate structure. Figure 6 As shown, the aluminum heat transfer plate 22 has through holes 221, such as... Figure 1 and Figure 7 As shown, a TDS probe 3 and a temperature sensor 9 are provided on the sinking platform 111. The structure and principle of the TDS probe 3 are existing technologies. For example, please refer to "A TDS Probe" in Chinese Utility Model Patent Publication No. CN209356436U; Figure 1 and Figure 7 As shown, the TDS probe 3 and temperature sensor 9 are positioned correspondingly. To accurately measure the water temperature at the location of the TDS probe 3, the temperature sensor 9 should be positioned close to the TDS probe 3. For example, in a horizontal plane, the distance between the temperature sensor 9 and the TDS probe 3 can be 15 mm to 25 mm. Figure 5 and Figure 6 As shown, the TDS probe 3 and the temperature sensor 9 are respectively located in the corresponding vias 221, meaning that there are two vias 221. Figure 1 and Figure 5 As shown, a control circuit board 8 is provided on the lower side of the heating plate assembly 2. The control circuit board 8 is electrically connected to the TDS probe 3 and the temperature sensor 9; Figure 4 and Figure 5 As shown, the kettle of this utility model also includes a display panel 51, and a control circuit board 8 is electrically connected to the display panel 51.

[0021] The electric heating disc assembly 2 heats the water body in the kettle body 1, the two probes 31 of the TDS probe 3 are immersed in the water body, the transformer on the control circuit board 8 supplies power to the TDS probe 3, the above-mentioned two probes 31 are electrically connected through the water body in the kettle body 1, the control circuit board 8 analyzes the current detected by the TDS probe 3, and compensates according to the detected temperature value of the water body by the temperature sensor 9 (to improve the accuracy of detecting water quality), realizes automatic intelligent detection of water quality, and the control circuit board 8 transmits the TDS detection data to the display panel 51 to show the user to view.

[0022] Since the kettle of the utility model directly embeds the TDS probe 3 and the temperature sensor 9 on the sunken platform 111, the TDS detection structure is integrated with the kettle body 1, the structure is relatively simple, the cumbersome operation of inserting the external TDS detection pen into the water is avoided, the trouble of carrying the external TDS detection pen separately from the kettle is avoided, thus being conducive to the convenience of water quality detection, and the unstable condition of the user's hand-held operation of the external TDS detection pen is avoided, thus being conducive to improving the stability and precision of water quality detection. Since the TDS probe 3 and the temperature sensor 9 are arranged in the corresponding via holes 221 respectively, and the electric heating disc assembly 2 transmits heat energy to the sunken platform 111 through the aluminum heat disc 22, and then the kettle bottom 11 heats the water body in the kettle body 1, the water body at the upper side position of the sunken platform 111 has a higher temperature, since the water temperature rises, the TDS value rises, in the process of heating the water body, the TDS probe 3 detects the water body with a relatively high temperature, and a higher value of the TDS of the water body in the kettle body 1 can be obtained, after temperature compensation calculation, if the TDS value does not exceed the limit, it can be more confirmed that the water quality of the water body is qualified, that is, the water quality detection is more strict. Figure 2 As shown in the drawing, the TDS probe 3 is arranged in the corresponding range of the aluminum heat disc 22 (in the perspective angle), instead of being arranged on the radial outer side of the aluminum heat disc 22, so that the TDS probe 3 is closer to the central part of the kettle bottom 11, when the user needs to clean the scale accumulated on the TDS probe 3, the hand or cleaning tool is relatively easy to reach the position of the TDS probe 3 from the upper end opening of the kettle body 1.

[0023] Further, as shown in the drawing, Figure 3As shown, the TDS probe 3 comprises a probe shell 30 and a probe needle 31, the probe needle 31 protrudes upwardly from the top of the probe shell 30, the upper part of the probe shell 30 is formed with a convex ring part 301, the lower part of the probe shell 30 is formed with an external thread part 302, the sealing ring 6 is arranged between the convex ring part 301 and the upper surface of the sink part 111, the nut 7 is screwed with the external thread part 302, the nut 7 abuts against the lower side of the aluminum heat transfer disc 22, thus, in the assembly process, the probe shell 30 passes through the sink part 111 and the corresponding through hole 221 downwardly, the sealing ring 6 is clamped and pressed between the convex ring part 301 and the upper surface of the sink part 111 by the thread locking force of the nut 7, thereby forming a good seal, the lead wire 32 of the TDS probe 3 can be led out from below the kettle bottom 11, and the lead wire 32 is connected to the control circuit board 8. For example, the temperature sensor 9 is provided with a silicone rubber sleeve, and the silicone rubber sleeve is formed with a flange, in the assembly process, the temperature sensor 9 passes through the corresponding through hole 211 and the sink part 111 upwardly, and the flange abuts against the lower side of the sink part 111.

[0024] Further, as shown in Figure 1 and Figure 4 , the kettle further comprises a bottom cover 5, the bottom cover 5 is in the shape of a basin, the bottom cover 5 is arranged on the lower side of the kettle bottom 11, and the control circuit board 8 is arranged in the bottom cover 5, so that the bottom cover 5 protects the control circuit board 8 and is also conducive to fully utilizing the internal space of the bottom cover 5, and the display panel 51 is arranged on one side of the bottom cover 5, so that the connection line between the control circuit board 8 and the display panel 51 can be simplified and shortened, and the bottom cover 5 can be an injection molding part.

[0025] Further, as shown in Figure 1 and Figure 5 , the bottom cover 5 is provided with a circuit board support 4, the circuit board support 4 is an injection molding part, the lower side of the kettle bottom 11 is provided with an upper coupler 10, in combination with Figure 2 and Figure 4 , the upper coupler 10 is used for electrically and coupledly connecting a lower coupler of a base of the kettle, as shown in Figure 5 , the circuit board support 4 is in the shape of an arc, the circuit board support 4 is arranged on the outer side of the upper coupler 10, since the upper coupler 10 is arranged on the corresponding lower side of the center of the kettle bottom 11, the circuit board support 4 is arranged in the shape of an arc, so that the circuit board support 4 can fully utilize the space on the outer side of the upper coupler 10, as shown in Figure 5 , the control circuit board 8 is mounted on the lower side of the circuit board support 4, specifically, the lower side of the circuit board support 4 is formed with a recess, and the control circuit board 8 is arranged in the recess, so as to position the control circuit board 8, and the control circuit board 8 can be mounted on the circuit board support 4 by corresponding screws. As shown in Figure 5 , the circuit board support 4 is formed with a fork 41, and the screws for fixedly connecting the bottom cover 5 and the upper coupler 10 pass through the corresponding fork 41.

[0026] Further, as shown in Figure 6 The electric heating disc assembly 2 comprises an electric heating tube 21 arranged at the lower side of the aluminum heat transfer disc 22. The outer shell of the electric heating tube 21 is integrally arranged with the aluminum heat transfer disc 22. The electric heating tube 21 is in an arc shape and is concentrically arranged with the kettle bottom 11. The through hole 221 is arranged between the two ends of the electric heating tube 21 (the two ends of the electric heating tube 21 are used for leading out electric wires). Thus, the through hole 221 is arranged in the region of the aluminum heat transfer disc 22 which is not occupied by the electric heating tube 21, and the through hole 221 is away from the upper coupler 10, so that the above layout is reasonable.
