[0056] The following will be combined with Figures 2 to 18 The liquid heating container provided by the embodiment of the present application is introduced. The liquid heating container can be an electric kettle, a health pot or a tea pot, etc., which is not listed one by one here.

[0057] As Figures 2 to 4As shown, the liquid heating container comprises: a container body 100, the bottom edge of the container body 100 is inwardly recessed to form a mounting table 110; a base 200, a support table 221 is arranged on the base 200 at a position corresponding to the mounting table 110, the container body 100 is placed on the base 200, and the lower surface of the mounting table 110 is arranged on the support table 221; and a liquid level detection piece 300 arranged on the support table 221, the liquid level detection piece 300 can detect whether the liquid 400 in the container body 100 is lower than the upper surface of the mounting table 110.

[0058] The liquid heating container provided by the embodiment of the present aspect sets the liquid level detection piece 300 at the support table 221 of the base 200 to detect whether the liquid level is lower than the upper surface of the mounting table 110, thereby preventing the dry burning phenomenon and achieving good dry burning prevention effect. Compared with the related art in which a protruding structure is additionally arranged on one side of the base to mount the liquid level detection piece and needs to be attached to the side wall of the container body to detect the liquid level, the protruding structure additionally arranged can be omitted, the appearance of the base 200 is beautiful, the appearance of the liquid heating container as a whole is also beautiful, and the visual effect is improved. Moreover, the cost increase caused by the additional protruding structure arranged on the top of the base 200 is avoided, and the production cost can be reduced.

[0059] In specific applications, for example, Figure 13 As shown, the liquid heating container is powered on, and the liquid level detection piece 300 starts to work. When the liquid level in the container body 100 is higher than the upper surface of the mounting table 110 at the bottom, it can be detected by the liquid level detection piece 300 and fed back to the liquid level detection circuit board in the base 200, at this time, the liquid heating container works normally. With the continuous boiling and evaporation of the liquid 400 in the container body 100, the liquid level in the container body 100 continues to drop, when the liquid level in the container body 100 is lower than the upper surface of the mounting table 110 at the bottom, the liquid level detection piece 300 cannot detect the liquid 400 and sends a feedback signal, and the liquid level detection circuit board judges dry burning and controls the heating disc 240 to stop heating after receiving the signal.

[0060] Further, in some embodiments, as shown in Figure 3 , Figure 4 , Figure 5 , Figure 14 and Figure 16 , the bottom of the container body 100 is embedded and placed on the top of the base 200, and the support table 221 is lower than the upper edge of the side wall of the base 200. The support table 221 is arranged to be sunken relative to the upper edge of the side wall of the base 200, which is good in appearance and the base 200 can limit the bottom of the container body 100 in the circumferential direction, which is conducive to the placement of the container body 100.

[0061] Specifically, the middle part of the upper surface of the base 200 can be concave downward, and the support platform 221 is located at the upper surface of the concave part. In this way, the concave part can accommodate the bottom of the container body 100 and support the container body 100 by using the support platform 221.

[0062] As an example, as shown in Figure 4 and Figure 5 , the base 200 includes a shell 210 and a heat shield 220, the inner side wall of the shell 210 is provided with a first connecting rib 211 at the top; the heat shield 220 is arranged in the interior of the shell 210, and the outer side wall of the heat shield 220 is provided with a second connecting rib, which is arranged on the first connecting rib 211. The second connecting rib is configured as the support platform 221. Here, a part of the first connecting rib 211 can be extended downward, so that the position of the second connecting rib is lower than the side wall of the shell 210, facilitating the bottom of the container body 100 to be embedded on the top of the base 200 and arranged on the support platform 221.

[0063] Of course, the support platform 221 can also be at the same height as the upper edge of the side wall of the base 200. As long as the support platform 221 does not protrude upward relative to the side wall of the base 200, the base 200 has good appearance aesthetics.

[0064] For the specific arrangement position of the liquid level detection member 300, further, in some embodiments, as shown in Figures 6 to 11 , the liquid level detection member 300 is arranged on the upper surface of the support platform 221, and the liquid level detection member 300 can be in contact with the lower surface of the mounting platform 110. This is conducive to the liquid level detection member 300 accurately sensing the liquid level in the container body 100.

[0065] In a specific embodiment, as shown in Figure 11 and Figure 12 , the mounting platform 110 is annular, and the liquid level detection member 300 is annular, and the liquid level detection member 300 is distributed circumferentially along the base 200 and can be in circumferential contact with the lower surface of the mounting platform 110. Here, the liquid level detection member 300 is annular, which can circumferentially sense whether the liquid level is lower than the upper surface of the mounting platform 110, and the detection is more accurate.

[0066] As shown in Figure 7 , Figure 8 , Figure 11 and Figure 12 , the edge of the liquid level detection member 300 is provided with a bendable lug 310, and the support platform 221 is provided with a mounting hole 2211, and the lug 310 is bent to tightly hold the support platform 221 after passing through the mounting hole 2211. The mounting structure is simple and convenient to install. Moreover, the use of screws and other structures for assembly is avoided, and the risk of electric leakage is reduced.

[0067] As shown in Figure 12As shown, the lugs 310 can be distributed on both sides of the liquid level detection member 300 close to and away from the center of the base 200. At this time, the liquid level detection member 300 has double-row lugs 310, which are firm and reliable to install.

[0068] Of course, the liquid level detection member 300 can also be connected with the support table 221 through a buckle or other structure, not limited to the lugs 310, which are not listed one by one here.

[0069] The liquid heating container also includes a liquid level detection circuit board (not shown in the figure), which is arranged inside the base 200. As shown in Figure 9 Figure 10 Figure 11 Figure 12 As shown, the liquid level detection member 300 is provided with a downwardly extending terminal 320, and the support table 221 is provided with a first avoiding hole 2212, and the terminal 320 extends into the inside of the base 200 through the first avoiding hole 2212 to be electrically connected with the liquid level detection circuit board. Here, the terminal 320 is used to pass through the first avoiding hole 2212 on the support table 221 to be electrically connected with the liquid level detection circuit board, which is simple in structure and convenient and reliable in connection.

[0070] In a specific application, as shown in Figures 7 to 12 The inner edge and the outer edge of the liquid level detection member 300 are uniformly distributed with six pairs of lugs 310, each pair of lugs 310 includes two lugs 310 inside and outside, and a standard specification of a terminal pin is arranged at a specified position of the liquid level detection member 300. The top of the heat shield 220 is provided with a mounting hole 2211 for the lugs 310 to pass through, and a first avoiding hole for the terminal pin to pass through; the liquid level detection member 300 is fixed by being tightly held by the support table 221 of the heat shield 220 through the six pairs of lugs 310, and the terminal pin is connected with the liquid level detection circuit board inside the base 200 through a lead wire.

[0071] In another specific embodiment, as shown in Figure 14 Figure 15 The mounting table 110 is annular, the liquid level detection member 300 is block-shaped, and the liquid level detection member 300 can contact the lower surface of the mounting table 110. Compared with the annular liquid level detection member 300, the block-shaped liquid level detection member 300 is small in size and can reduce material use and save costs.

[0072] For the mounting method of the block-shaped liquid level detection member 300, it can be similar to the above-mentioned annular liquid level detection member 300. The block-shaped liquid level detection member 300 can also have a bendable lug 310, and the support table 221 is provided with a mounting hole 2211, and the lug 310 is bent to tightly hold the support table 221 after passing through the mounting hole 2211. As shown in Figure 15 The lug 310 has two pairs, and each pair of two lugs 310 is symmetrically distributed on both sides of the liquid level detection member 300 in the radial direction of the base 200.​​​​

[0073] For the wiring mode of the block-shaped liquid level detection piece 300, it can also be similar to the above-mentioned annular liquid level detection piece 300. As shown in Figure 15 The block-shaped liquid level detection piece 300 is provided with a downwardly extending wiring terminal 320, and the support table 221 is provided with a first avoiding hole 2212. The wiring terminal 320 extends into the inside of the base 200 through the first avoiding hole 2212 to be electrically connected with the liquid level detection circuit board.

[0074] The liquid level detection piece 300 can be rectangular or arc-shaped block. The center of the arc corresponds to the center of the upper surface of the base 200.

[0075] For the specific setting position of the liquid level detection piece 300, further, in another embodiment, as shown in Figures 16 to 18 The liquid level detection piece 300 is located below the support table 221, and the liquid level detection piece 300 can detect whether the liquid 400 in the container body 100 is lower than the upper surface of the mounting table 110 through the support table 221.

[0076] In these embodiments, since the liquid level detection piece 300 is hidden below the support table 221, on the one hand, the appearance is improved, on the other hand, the user can avoid touching the liquid level detection piece 300 by mistake, guaranteeing the electrical safety requirements, and being safe. Moreover, it can reduce the probability of the liquid level detection piece 300 being polluted by dust and other impurities, and improve the service life of the liquid level detection piece 300.

[0077] In this case, the liquid level detection piece 300 can be annular or block-shaped.

[0078] In one specific embodiment, as shown in Figures 16 to 18 The base 200 includes: an outer shell 210, the top of the outer shell 210 has a first connecting rib 211 extending inwardly; a heat shield 220 is arranged on the top of the outer shell 210, and the outer edge of the heat shield 220 has a second connecting rib arranged on the first connecting rib 211. The second connecting rib is configured as the support table 221. The liquid level detection piece 300 is block-shaped and clamped between the first connecting rib 211 and the second connecting rib.

[0079] In this embodiment, the heat shield 220 is arranged on the first connecting rib 211 of the outer shell 210 through the second connecting rib, and the liquid level detection piece 300 is clamped between the first connecting rib 211 and the second connecting rib, so that the liquid level detection piece 300 has good installation stability.

[0080] Further, the part of the first connecting rib 211 protrudes inward to support the liquid level detecting member 300, which can increase the contact area between the outer shell 210 and the liquid level detecting member 300, and improve the installation stability of the liquid level detecting member 300. In addition, a limiting groove can be arranged on the first connecting rib 211, and a part of the liquid level detecting member 300 is embedded in the limiting groove to prevent the liquid level detecting member 300 from moving.

[0081] The liquid heating container further comprises a liquid level detecting circuit board (not shown in the figure), which is arranged inside the base 200. As shown in Figure 17 and Figure 18 The liquid level detecting member 300 is arranged with a downward extending wiring terminal 320, and the second connecting rib is arranged with a second avoiding hole 212. The wiring terminal 320 extends into the inside of the base 200 through the second avoiding hole 212 to be electrically connected with the liquid level detecting circuit board. Here, the wiring terminal 320 is used to pass through the second avoiding hole 212 on the outer shell 210 to be electrically connected with the liquid level detecting circuit board, which is simple in structure and convenient and reliable in connection.

[0082] Of course, in other embodiments, the liquid level detecting member 300 can also be attached to the lower surface of the supporting table 221 of the heat insulation cover 220, and be suspended below with a gap between the outer shell 210, so that the avoiding hole does not need to be arranged on the outer shell 210, which is convenient for wiring.
