Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a liquid heater with accurate detection. Background Art

[0002] With the progress of technology, most of the current anti-overflow detection methods for kitchen appliances are non-contact detection, that is, a detection board is fixedly arranged on the outer side of a glass cup body, and capacitive electrodes capable of non-contact sensing of the liquid level signal in the cup body are arranged on the detection board to prevent food from overflowing.

[0003] In order to enable the detection board and the cup body to have a relatively better positioning relationship. The applicant previously filed a patent application with the application number CN201720526032.4. In this patent, the capacitive induction board is positioned on the outer side wall of the glass cup through the handle shell. During the installation process, two symmetric and oppositely joined handle covers need to clamp the handle while clamping the capacitive induction board, so as to realize the positioning of the capacitive induction board while fixing the handle shell, ensuring the relative position relationship between the capacitive induction board and the glass cup body. Although in this scheme, the capacitive induction board and the glass cup body are in a relatively fixed relationship and there is no displacement between them, in this structure, a handle needs to be provided on the glass cup body to position the handle shell, and then the capacitive induction board is fixed and limited through the positioning of the handle shell. Not only is the installation structure complex, but when there is an assembly error between the handle shell and the handle, it will cause the problem that the capacitive induction board detects the liquid level signal inaccurately. Based on this, how to reliably and accurately position and install the rigid liquid level detection board on the outer wall of the arc-shaped glass cup has always been a difficulty for R & D engineers to apply the non-contact detection technology to the liquid level detection of kitchen appliances.

[0004] During the further research process, the applicant also filed an application with the application number CN2024103319154, which directly presses the detection board with a positioning board to press the detection board against the outer wall of the glass cup body. A receiving cavity for receiving the detection board is formed by enclosing the positioning board and the peripheral wall of the glass cup body, and the detection board is installed by pouring glue into the receiving cavity, effectively solving the problem of reliably and accurately fixing the detection board to the outer wall of the curved glass cup. However, with the applicant's further research, the applicant found that when the glue solidifies, the position of the detection board relative to the glass cup body will change slightly, resulting in a problem of decreased accuracy. Summary of the Utility Model

[0005] The utility model provides a liquid heater with accurate detection, which solves the problem that the floating of the detection board caused by the curing of the glue will change the position of the detection board relative to the glass cup body, resulting in a decrease in detection sensitivity and accuracy.

[0006] The technical solution adopted by the utility model is as follows:

[0007] The utility model provides a liquid heater with accurate detection, comprising a glass cup body and a strip-shaped detection plate for detecting liquid level in the air, wherein the detection plate is vertically installed on the peripheral wall of the glass cup body, and a positioning groove for accommodating the detection plate is provided on the outer side of the glass cup body, and the detection plate is encapsulated by pouring glue into the positioning groove to form a glue layer, and the liquid heater also includes a blocking cover covering the outer side of the positioning groove, and a pressing body is provided on the side of the blocking cover facing the glass cup body, and the pressing body has a pressing surface, and the blocking cover is pressed on the surface of the glue layer by the pressing surface of the pressing body.

[0008] The utility model provides a liquid heater with accurate detection. By arranging a positioning groove for accommodating the detection plate on the outside of the glass cup body, the detection plate is directly placed in the accommodating groove to achieve direct positioning, avoiding positioning errors caused by clamping the handle and the cup body, which is conducive to improving the position accuracy of the detection plate. By pouring glue into the positioning groove to form a glue layer, the glue layer reliably encapsulates the detection plate in the positioning groove to achieve good fixing and sealing effects. By arranging a blocking cover covering the outside of the positioning groove, a pressure holding body is provided on the side of the blocking cover facing the glass cup body, and the pressure holding body has a pressure holding surface. The blocking cover is pressed on the surface of the glue layer by the pressure holding surface of the pressure holding body. Therefore, after pouring glue into the positioning groove, the baffle cover is used to cover it and the pressing surface of the pressing body is used to press the liquid surface of the glue. Since the pressing surface presses the glue, the glue is suppressed from expanding outward during the curing process, so as to reduce the probability of the detection plate floating to the side away from the glass cup body with the expanding glue, effectively avoiding the distance between the detection plate and the glass cup body from becoming larger, shortening the detection distance of the detection plate, and realizing sensitive detection. In addition, the pressing surface of the pressing body directly presses the liquid surface of the glue, which can also make the cured glue layer denser, avoid the formation of bubbles, etc., improve the sealing effect, and fix more securely.

[0009] In a preferred embodiment, the detection plate divides the positioning groove into an inner chamber close to the glass cup body and an outer chamber away from the glass cup body, the inner chamber is connected to the outer chamber, and the detection board is encapsulated by filling the inner chamber and the outer chamber with glue.

[0010] The positioning groove is divided into an inner chamber close to the glass cup body and an outer chamber away from the glass cup body by the detection plate. During the glue pouring process, the glue is filled in the inner chamber and the outer chamber, so that each side of the detection plate is in contact with the glue, which not only ensures the reliability of comprehensive positioning and fixation of the detection plate, but also realizes the comprehensive waterproof sealing of the detection plate.

[0011] More preferably, the edge of the detection plate abuts against the inner side wall of the positioning groove, and a concave connecting groove is provided on the inner side wall of the positioning groove or on the edge of the detection plate, and the connecting groove connects the inner chamber with the outer chamber;

[0012] Alternatively, a limiting portion protrudes from the inner sidewall of the positioning groove, the detection plate is clamped in the positioning groove through the limiting portion, a glue application gap is formed between the edge of the detection plate and the inner sidewall of the positioning groove, and the glue application gap communicates the inner cavity with the outer cavity.

[0013] More preferably, the outer surface of the peripheral wall of the glass cup body is a curved surface concave towards the center of the glass cup body, the detection plate abuts against the peripheral wall of the glass cup body, the inner cavity is formed between the detection plate and the peripheral wall of the glass cup body, and the horizontal cross-section of the inner cavity is crescent-shaped;

[0014] Alternatively, the outer surface of the peripheral wall of the glass cup body is a curved surface protruding outwards, the detection plate abuts against the peripheral wall of the glass cup body, the inner cavity includes a first inner cavity and a second inner cavity separated by the abutting portion of the detection plate and the glass cup body, and at least the first inner cavity communicates with the outer cavity.

[0015] In a preferred embodiment, the pressing body and the retaining cover are integrally formed.

[0016] In a preferred embodiment, the pressing body is an elastic body.

[0017] By using an elastic body to press the glue liquid, on the premise of achieving the effect of inhibiting the expansion of the glue liquid to ensure the detection sensitivity, when the retaining cover is fixed too tightly, there is a certain buffering effect between the pressing surface and the glue liquid, which can avoid damage to the glue filling layer by the pressing surface, and after the glue liquid solidifies into the glue filling layer, a certain pre-tightening force is formed between the retaining cover and the glass cup body, preventing the retaining cover from bulging outwards and the retaining cover from loosening and having unreliable cooperation with the glass cup body due to hard pressing of the glue liquid.

[0018] In a preferred embodiment, the pressing body is a flexible tube, the flexible tube is arranged vertically along the retaining cover, and the outer wall of the flexible tube forms the pressing surface.

[0019] Using a flexible tube as the pressing body has a simple structure, can save processing costs, and the outer wall of the flexible tube forms the pressing surface, which is convenient for realizing the comprehensive pressing of the surface of the glue liquid, effectively avoiding the situation of glue solidification and expansion, improving the detection sensitivity, and the flexible tube has a certain elastic deformation ability to avoid damage to the glue filling layer and improve the cooperation reliability between the retaining cover and the glass cup body.

[0020] In a preferred embodiment, the pressing body is a silica gel block.

[0021] The pressing body is a silica gel block, which has a simple structure, saves processing costs, realizes comprehensive pressing on the surface of the glue liquid, improves detection sensitivity, and can all have elastic deformation ability to avoid damage to the potting layer and improve the cooperation reliability between the baffle and the glass cup body.

[0022] In a preferred embodiment, the pressing body includes a pressing piece and a spring abutted between the pressing piece and the baffle.

[0023] The pressing body adopts the cooperation mode of the pressing piece and the spring. By using the pressing piece to comprehensively press the surface of the glue liquid, the potting layer becomes more dense, and the sealing effect and positioning effect are improved. By using the spring to abut between the pressing piece and the baffle, after the glue liquid solidifies, there is a pre-tightening force between the baffle and the glass cup body, realizing reliable fixation of the baffle.

[0024] In a preferred embodiment, the pressing body further includes bump points protruding from the pressing surface, and the bump points pass through the potting layer and abut against the outside of the detection plate.

[0025] By arranging bump points on the pressing surface of the pressing body, and the bump points pass through the potting layer and abut against the outside of the detection plate to achieve direct pressing connection to the detection plate. At the same time, the pressing surface presses the surface of the glue liquid, achieving the effect of double positioning of the detection plate. It can position the detection plate during the curing process of the glue liquid and also position the detection after the glue liquid cures, realizing the long-term and effective close contact between the detection plate and the glass cup body, and further ensuring the detection sensitivity.

[0026] In a preferred embodiment, a positioning groove is formed by the outer surface of the peripheral wall of the glass cup body being recessed;

[0027] Alternatively, a rib is integrally protruded from the outer surface of the peripheral wall of the glass cup body, and the rib encloses to form the positioning groove.

[0028] By forming the positioning groove by the outer surface of the peripheral wall of the glass cup body being recessed or integrally protruding a rib, the detection plate can be more directly fixed to the peripheral wall of the glass cup body, reducing the assembly error, improving the accuracy of the position of the detection plate, and thus improving the detection accuracy.

[0029] In a preferred embodiment, a positioning bracket is fixed on the outer side of the peripheral wall of the glass cup body. The positioning bracket is provided with a surrounding edge that closely cooperates with the peripheral wall of the glass cup body, and the surrounding edge encloses to form the positioning groove.

[0030] By forming the positioning groove on the peripheral wall of the glass cup body with the surrounding edge of the positioning bracket, the detection plate can be directly fixed to the peripheral wall of the glass cup body, reducing the assembly error, improving the accuracy of the position of the detection plate, and thus improving the detection accuracy. At the same time, it can simplify the processing technology of the glass cup body and facilitate production and manufacturing.

[0031] In a preferred embodiment, the liquid heater further includes an upper mounting seat fixed at the mouth of the glass cup body and a cup base fixed at the bottom of the glass cup body. The top of the shielding cover is fixedly connected to the mounting seat, and the bottom of the shielding cover is fixedly connected to the cup base;

[0032] Alternatively, the shielding cover and the glass cup body are fixedly bonded;

[0033] Alternatively, the liquid heater further includes a handle fixed on the outer side of the glass cup body, and the handle clamps and fixes the shielding cover on the outer side of the glass cup body.

[0034] Since it is difficult to process positioning holes in the glass cup body, etc., and the setting of positioning holes is not conducive to the sealing and structural strength improvement of the glass cup body, the upper and lower fixing of the shielding cover is carried out by using the mounting seat and the cup base. The shielding cover is fixed more reliably and the drilling damage to the glass cup body is avoided; by means of the bonding and fixing method, the fixing method is more convenient and the assembly efficiency is improved; the handle and the glass cup body are used to clamp the shielding cover, which simplifies the assembly steps and improves the assembly efficiency.

[0035] In a preferred embodiment, the liquid heater further includes a handle fixed on the side of the glass cup body, and the handle forms the shielding cover.

[0036] By forming the handle into the shielding cover, the function of the handle is diversified. It can not only facilitate the taking and holding of the glass cup body, but also press the glue, improve the sensitivity of the detection board, with a compact structure and a simplified overall structure.

[0047] In the following description, many specific details are set forth in order to fully understand the present utility model.

Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0049] In the present utility model, unless otherwise clearly defined and limited, the terms "mount", "connect", "couple", "fix", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection, or a communication connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0050] In the present utility model, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0051] like Figures 1-4 As shown, the utility model provides a liquid heater with accurate detection, including a glass cup body 10 and a strip-shaped detection plate 20 for detecting liquid level in the air, the detection plate 20 is vertically installed on the peripheral wall of the glass cup body 10, and a positioning groove 11 for accommodating the detection plate 20 is provided on the outer side of the glass cup body 10, and the detection plate 20 is encapsulated by pouring glue into the positioning groove 11 to form a glue layer, and the liquid heater also includes a blocking cover 40 covering the outer side of the positioning groove 11, and a pressing body 50 is provided on the side of the blocking cover 40 facing the glass cup body 10, and the pressing body has a pressing surface, and the blocking cover is pressed on the surface of the glue layer by the pressing surface of the pressing body.

[0052] The utility model provides a liquid heater with accurate detection. By arranging a positioning groove 11 for accommodating a detection plate 20 on the outer side of a glass cup body 10, the detection plate 20 is directly placed in the accommodating groove to achieve direct positioning, thereby avoiding positioning errors caused by clamping the handle and the cup body, and helping to improve the position accuracy of the detection plate 20. By pouring glue into the positioning groove 11, the glue layer 30 reliably encapsulates the detection plate 20 in the positioning groove 11, thereby achieving good fixing and sealing effects. By setting a blocking cover 40 covering the outside of the positioning groove 11, a pressing body 50 is provided on the side of the blocking cover 40 facing the glass cup body 10, and the pressing body 50 has a pressing surface that presses on the surface of the glue filling layer 30. Therefore, after the glue is poured into the positioning groove 11, the blocking cover 40 is used to block and the pressing surface of the pressing body 50 is used to press the liquid surface of the glue. Since the pressing surface presses the glue, the glue is suppressed from expanding outward during the curing process, so as to reduce the probability of the detection plate 20 floating to the side away from the glass cup body 10 with the expanding glue, so as to avoid the distance between the detection plate 20 and the glass cup body 10 from becoming larger, thereby shortening the detection distance and realizing sensitive detection; in addition, the pressing surface of the pressing body 50 directly presses the liquid surface of the glue, which can also make the cured glue filling layer 30 denser, avoid the occurrence of bubbles, etc., improve the sealing effect, and fix more securely.

[0053] The present utility model does not limit the specific structure of the pressing body 50, and any of the following implementation examples can be adopted:

[0054] Implementation example 1, as Figures 1-4 shown, the pressing body 50 is an elastic body. Specifically, the elastic body can be a sponge block, a silica gel block, a rubber block, etc.

[0055] By using an elastic body to press the glue liquid, on the premise of achieving the effect of suppressing the expansion of the glue liquid to ensure the detection sensitivity, when the cover 40 is fixed too tightly, there is a certain buffering effect between the pressing surface and the glue liquid, which can avoid damage to the glue filling layer 30 by the pressing surface. And after the glue liquid solidifies into the glue filling layer 30, a certain pre-tightening force is formed between the cover 40 and the glass cup body 10, preventing the cover 40 from bulging outwards and the looseness and unreliable cooperation between the cover 40 and the glass cup body 10 due to hard pressing of the glue liquid. The pressing body 50 is a sponge block or a silica gel block, with a simple structure, saving processing costs, realizing full pressing of the glue liquid surface, improving the detection sensitivity, and both having the ability of elastic deformation to avoid damage to the glue filling layer 30 and improving the cooperation reliability between the cover 40 and the glass cup body 10.

[0056] In this implementation example, as Figures 1-4 shown, a positioning groove 11 is formed by the outer surface of the peripheral wall of the glass cup body 10 being recessed;

[0057] Of course, the positioning groove 11 is not limited to this way. For example, in other implementation manners, a rib is integrally protruded on the outer surface of the peripheral wall of the glass cup body 10, and the rib encloses to form the positioning groove 11. Or, in other implementation manners, a positioning bracket 60 is fixed on the outer side of the peripheral wall of the glass cup body 10. The positioning bracket 60 is provided with a surrounding edge 61 that closely cooperates with the peripheral wall of the glass cup body 10, and the surrounding edge 61 encloses to form the positioning groove 11.

[0058] By forming the positioning groove 11 by the outer surface of the peripheral wall of the glass cup body 10 being recessed or integrally protruding a rib, the detection plate 20 can be more directly fixed to the peripheral wall of the glass cup body 10, reducing the assembly error, improving the accuracy of the position of the detection plate 20, and thus improving the detection accuracy.

[0059] It should be noted that the specific formation manner of the above positioning groove 11 can also be applied to other implementation examples.

[0060] In this implementation example, as Figure 1 shown, the liquid heater further includes an upper mounting seat fixed at the cup mouth of the glass cup body 10 and a cup seat fixed at the bottom of the glass cup body 10. The top of the cover 40 is fixedly connected to the mounting seat, for example, by plugging and matching, and the bottom of the cover 40 is fixedly connected to the cup seat, for example, by screws;

[0061] Of course, in other embodiments, the shielding cover 40 is fixedly attached to the glass cup body 10 by adhesion; alternatively, the liquid heater further includes a handle fixed to the outer side of the glass cup body 10, and the handle clamps and fixes the shielding cover 40 to the outer side of the glass cup body 10.

[0062] It can be understood that the above-mentioned fixing method of the shielding cover 40 and the glass cup body 10 is applicable to other implementation examples.

[0063] Since it is difficult to process positioning holes on the glass cup body 10 and the setting of positioning holes is not conducive to the sealing and structural strength improvement of the glass cup body 10, therefore, the mounting seat and the cup seat are used to fix the shielding cover 40 up and down. The shielding cover 40 is fixed more reliably and the drilling damage to the glass cup body 10 is avoided; by means of the adhesion fixing method, the fixing method is more convenient and the assembly efficiency is improved; the handle and the glass cup body 10 are used to clamp the shielding cover 40, which simplifies the assembly steps and improves the assembly efficiency.

[0064] In addition, in this implementation example, as Figures 1-4 shown, the detection plate 20 divides the positioning groove 11 into an inner cavity 111 close to the glass cup body side and an outer cavity 112 far from the glass cup body side. The inner cavity is communicated with the outer cavity, and the detection plate is encapsulated by filling glue in the inner cavity and the outer cavity.

[0065] Regarding the communication method between the inner cavity and the outer cavity, optionally, the edge of the detection plate abuts against the inner side wall of the positioning groove, and a recessed communication groove is provided on the inner side wall of the positioning groove or the edge of the detection plate. The communication groove communicates the inner cavity with the outer cavity;

[0066] Or, a limiting portion is convexly provided on the inner side wall of the positioning groove, the detection plate is clamped in the positioning groove by the limiting portion, and a glue passing gap is formed between the edge of the detection plate and the inner side wall of the positioning groove. The glue passing gap communicates the inner cavity with the outer cavity.

[0067] Of course, a communication groove can also be provided through the detection plate to communicate the inner cavity with the outer cavity.

[0068] The detection plate divides the positioning groove into an inner cavity close to the glass cup body side and an outer cavity far from the glass cup body side. During the glue filling process, the glue fills the inner cavity and the outer cavity, so that each side of the detection plate contacts the glue, which not only ensures the comprehensive positioning and fixing reliability of the detection plate, but also realizes the comprehensive waterproof sealing of the detection plate.

[0069] As Figure 2 shown, the outer surface of the peripheral wall of the glass cup body is a curved surface concave towards the center of the glass cup body. The detection plate abuts against the peripheral wall of the glass cup body, and the inner cavity is formed between the detection plate and the peripheral wall of the glass cup body, and the horizontal cross section of the inner cavity is crescent-shaped;

[0070] Of course, it should be noted that the glass cup body is not limited to this. For example, in other embodiments, the outer surface of the peripheral wall of the glass cup body is a curved surface protruding outward, the detection plate is pressed tightly against the peripheral wall of the glass cup body, the inner cavity includes a first inner cavity and a second inner cavity separated by the pressed part of the detection plate and the glass cup body, and at least the first inner cavity communicates with the outer cavity.

[0071] In this embodiment, as Figure 1 , Figure 3 shown, the liquid heater is a food processor that does not need to be hand-washed. A crushing knife (not shown) is provided in the glass cup body 10, and the liquid heater further includes a motor (not shown) for driving the crushing knife.

[0072] Embodiment 2, as Figure 5 shown, the pressing body 50 is an elastic body, specifically a flexible tube 51. The flexible tube 51 is arranged vertically along the baffle 40, and the outer wall of the flexible tube 51 forms a pressing surface.

[0073] Using the flexible tube 51 as the pressing body 50 has a simple structure, can save processing costs, and the outer wall of the flexible tube 51 forms a pressing surface, which is convenient for realizing the full pressing of the surface of the glue liquid, effectively avoiding the situation of glue liquid curing and swelling, improving the detection sensitivity. The flexible tube 51 has a certain elastic deformation ability to avoid damage to the glue filling layer 30 and improve the matching reliability between the baffle 40 and the glass cup body 10.

[0074] Embodiment 3, as Figure 6 , Figure 7 shown, the pressing body 50 includes a pressing piece 52 and a spring 53 abutted between the pressing piece 52 and the baffle 40.

[0075] The pressing body 50 adopts the cooperation mode of the pressing piece 52 and the spring 53. By using the pressing piece 52 to fully press the surface of the glue liquid, the glue filling layer 30 becomes more dense, and the sealing effect and positioning effect are improved. By using the spring 53 to abut between the pressing piece 52 and the baffle 40, after the glue liquid solidifies, there is a pre-tightening force between the baffle 40 and the glass cup body 10, realizing the reliable fixation of the baffle 40.

[0076] In this embodiment, as Figure 6 shown, a positioning bracket 60 is fixed on the outer side of the peripheral wall of the glass cup body 10. The positioning bracket 60 is provided with a surrounding edge 61 that fits closely with the peripheral wall of the glass cup body 10, and the surrounding edge 61 encloses to form a positioning groove 11.

[0077] By means of the surrounding edge 61 of the positioning bracket 60 to form the positioning groove 11 on the peripheral wall of the glass cup body 10, the detection plate 20 can be directly fixed to the peripheral wall of the glass cup body 10, reducing the assembly error, improving the accuracy of the position of the detection plate 20 to improve the detection accuracy, and at the same time being able to simplify the processing technology of the glass cup body 10, facilitating production and manufacturing.

[0078] In this embodiment, as Figure 6 shown, the liquid heater further includes a handle fixed to the side of the glass cup body 10, and the handle forms a shielding cover 40.

[0079] By forming the handle into the shielding cover 40, the functions of the handle are diversified. It can not only facilitate the grasping of the glass cup body 10, but also press and hold the glue, improving the sensitivity of the detection board 20. The structure is compact and the overall structure of the machine is simplified.

[0080] In this embodiment, the liquid heater is an integrated food processor with the motor placed below. A crushing knife is arranged inside the glass cup body 10, and a motor is fixedly arranged at the bottom of the glass cup body 10.

[0081] Embodiment 4: The pressing body 50 is a part of the shielding cover 40, that is, the pressing body 50 and the shielding cover 40 are integrally formed. The shielding cover 40 has a shielding surface that shields the positioning groove 11, and this shielding surface forms a pressing surface.

[0082] In a more preferred embodiment of the present utility model, the pressing body 50 further includes bumps protruding from the pressing surface. The bumps pass through the potting layer 30 and abut against the outside of the detection board 20. Preferably, the bumps are arranged in an array on the pressing surface.

[0083] By arranging bumps on the pressing surface of the pressing body 50, the bumps pass through the potting layer 30 and abut against the outside of the detection board 20 to achieve direct pressing of the detection board 20. At the same time, the pressing surface presses the surface of the glue, achieving the effect of double positioning of the detection board 20. It can not only position the detection board 20 during the curing process of the glue, but also position the detection after the glue is cured, realizing the long-term and effective close fitting of the detection board 20 and the glass cup body 10, and further ensuring the sensitivity of the detection.

[0084] It should be noted that the liquid heater provided by the present utility model is not limited to the above-mentioned food processor. In fact, the liquid heater can also be a head-type soybean milk machine with the motor placed above, a wall breaker whose glass cup body 10 can be detached from the main machine; or, the liquid heater can also be a health care pot, a boiling water pot, etc.

[0085] In addition, the present utility model does not limit the specific structure of the detection board. For example, the detection board includes a detection area provided with capacitive electrode plates and a processing area provided with a processing chip. Among them, the capacitive electrode plates include anti-overflow capacitive electrode plates, water level capacitive electrode plates, lid-closing capacitive electrode plates, etc.

[0086] What has not been described in the present utility model can be realized by adopting or referring to the existing technologies.

[0087] Each embodiment in this specification is described in a progressive manner. For the same or similar parts among the embodiments, reference can be made to each other, and the key point of each embodiment is to illustrate the differences from other embodiments.
