Description

TECHNICAL FIELD

[0002] The patent with the application number CN201720526032.4 discloses a food processor with good anti-overflow effect, a capacitive sensing plate which does not contact food and can sense the height of food is arranged on the outer sidewall of the stirring cup, so that the water level detection structure can accurately monitor the liquid level of food in the stirring cup and prevent liquid overflow. However, in the structure, the lower end of the handle occupies the installation space along the vertical direction of the outer side of the stirring cup, so that the lowest end of the existing capacitive sensing plate is arranged at a position higher than the lower end of the handle to avoid interference, which will raise the lower limit of the capacitive sensing plate, resulting in a large detection blind area in the lower part of the cup body and the situation that low water level detection and dry burning detection cannot be performed.

[0003] The applicant has also proposed a liquid heater with comprehensive liquid level detection, which includes a glass cup body and a mounting seat sleeved at the lower part of the glass cup body, a first positioning groove is arranged on the outer wall of the glass cup body, and a second positioning groove is arranged on the outer wall of the mounting seat and extends from the first positioning groove, the two positioning grooves accommodate a detection plate, and glue is poured into the positioning grooves to encapsulate the detection plate. According to the scheme, the detection plate is installed across the gap between the cup body and the mounting seat, the detection area of the glass cup body in the height direction is expanded, and the detection blind area is reduced.

[0004] However, the applicant found in further research that, due to the assembly error between the mounting seat and the glass cup body, the first positioning groove and the second positioning groove are misaligned and have a butt joint gap, and there is a glue leakage phenomenon, in addition, an annular gap is naturally formed between the glass cup body and the mounting seat, and the glue solution may also leak into the annular gap, causing waste of glue solution, and if the glue solution leaks along the annular gap between the heating disc and the cup body or between the mating positions of other components, the processing cavity may be filled with glue, and after the glue solidifies, the disassembly and assembly of other components will be affected, which is not conducive to disassembly and maintenance. Moreover, even if the installation bracket is used to form the positioning groove for glue pouring, in order to install the detection plate and the glass cup body, the outer side of the mounting seat needs to be lower than the outer side of the glass cup body, otherwise interference will occur, and in the case that the glass cup body and the cup base are in a sleeved relationship and the processing precision of the cup base is limited, the mounting bracket and the cup base cannot be matched, which will cause a gap between the cup base and the mounting bracket and a glue leakage problem.

[0079] Of course, in another preferred embodiment, the installation sequence of the detection plate 20 is as follows: after the mounting bracket 40 is fixed to the glass cup body 10, for example, a back glue is arranged on the back of the mounting bracket 40 to form a sticking layer 43, so as to achieve adhesion to the glass cup body 10, then the detection plate 20 is placed in the glue pouring groove, then glue is poured into the glue pouring groove, and after the glue solidifies, the detection plate 20 is packaged in the glue pouring groove.

[0080] The utility model does not make limitation to the structure of the liquid heater, for example, the liquid heater can be selected as a food processor, a smashing knife is arranged in the inside of the glass cup body 10, the function of smashing soybean milk and juice is realized, or the liquid heater can be selected as a boiling water pot, of course, the liquid heater can also be selected as a health pot and the like.

[0081] The places not described in the utility model can be realized by using or referring to the existing technology.

[0082] Each embodiment in the specification adopts a progressive mode for description, and the same and similar parts between each embodiment can be referred to each other, and each embodiment mainly describes the difference from other embodiments.
