Description

Technical Field

[0001] The present application relates to the field of small household appliances, and in particular to a liquid heater. Background Art

[0002] In the prior art, such as in Chinese utility model patent CN215127293U, the water level detector (detection board) is usually arranged on the kettle body, the control panel (control module) is arranged on the power base, and the control module and the water level detector are respectively electrically connected to the circuit board (power board) through a wiring harness.

[0003] Among them, the liquid level height inside the glass cup body is controlled by a detection board set in the liquid heater, the control module is used to control the liquid heater to work under different functions, and the power board is used to obtain the signals transmitted by the detection board and the control module, and the transmitted signals are processed and used to control other components of the liquid heater.

[0004] Because the control module and the detection board are connected to the power board through wiring harnesses respectively, multiple interfaces need to be opened on the power board. Multiple interfaces are used for connecting different wiring harnesses on the control module and the detection board to the power board, which makes the overall layout of the power board complicated. More interface settings will also cause the power board to occupy a larger space and the total cost of the power board is higher.

[0005] At the same time, because the control module and the detection board are connected to the power board through multiple wiring harnesses, the wiring harness inside the liquid heater will be messy, which is not conducive to the regularity of the internal wiring harness. The messy wiring harness will also cause the wiring harness to extend to the outside of the liquid heater when the liquid heater split components are buckled together, so that during the buckling process, the wiring harness will be clamped between the two split components. If the wiring harness is clamped between the two components for a long time, the soft protective layer wrapped around the outside of the wiring harness will be easily damaged, and the wires inside the wiring harness will be exposed. If the user touches the exposed wires during the use of the liquid heater, it is easy to cause the risk of electric shock and cause a safety accident.

[0006] When there are many wiring harnesses inside the liquid heater, it is not easy for the installer to install the many wiring harnesses neatly during the installation process. The process of neatening the wiring harnesses is rather cumbersome, which reduces the work efficiency of the installer. Utility Model Content

[0007] The present application discloses a liquid heater, which solves the technical problems of complex design of a power board in the liquid heater, and wire clamping and low installation efficiency caused by messy wire harnesses.

[0008] A liquid heater of the present application includes a glass cup body. A detection board is provided on the outer surface of the side wall of the glass cup body. Capacitive electrodes are provided on the detection board to detect the liquid level height in the glass cup body. The liquid heater further includes a power board and a control module for controlling the liquid heater. The control module is electrically connected to the power board through the detection board, so that the control module transmits signals to the power board through the detection board.

[0009] The following also provides several optional ways, which are not additional limitations to the above overall solution, but only further supplements or optimizations. Without technical or logical contradictions, each optional way can be combined separately with the above overall solution, or multiple optional ways can be combined with each other.

[0010] Further, in order to improve the flexibility of installing the control buttons and enable the control buttons to be adaptively installed at the positions required by the liquid heater.

[0011] Optionally, the control module includes a control substrate provided with control buttons, and the control substrate is electrically connected to the detection board separately.

[0012] Optionally, the liquid heater includes a handle, and the handle includes a handle cover and a handle base having a receiving cavity. The control substrate is arranged in the receiving cavity, a control area is provided on the handle cover, and the control substrate is arranged corresponding to the control area.

[0013] Further, in order to facilitate the user to operate the liquid heater through the control buttons.

[0014] Optionally, the liquid heater includes a handle, and the handle includes a receiving cavity. A thin film panel is bonded to the outer surface of the handle, and the handle is provided with a wire routing hole for a wire harness to pass through.

[0015] Further, in order to improve the user's control experience, when the user uses the control module, the control module can produce a good feedback effect on the user.

[0016] Optionally, the control module includes a thin film panel provided with control buttons. A wire harness is provided on one of the thin film panel and the detection board, and a wire harness socket is provided on the other. The wire harness is inserted into the wire harness socket.

[0017] Further, in order to make the wire harness of the liquid heater more regular.

[0018] Optionally, the liquid heater includes a handle, the handle includes a housing having a receiving cavity, the thin film panel is bonded to the outer surface of the housing, a wire arranging hole is formed in the housing, and the wire harness extends into the interior of the receiving cavity through the wire arranging hole.

[0019] Further, in order to improve the integration of the detection board and increase the functions of the detection board.

[0020] Optionally, a processing chip for processing the electrical signals of the control module is provided on the detection board.

[0021] Further, in order to save the installation space of the liquid heater and at the same time facilitate the installation of the control module and the control buttons.

[0022] Optionally, the control module and the detection board are integrally formed by plugging.

[0023] Optionally, the control module includes a control substrate and control buttons, and the control substrate is integrally formed with the detection board.

[0024] Optionally, an installation member covering the outside of the detection board is provided on the outside of the glass cup body, and the control buttons are exposed outside the installation member.

[0025] Optionally, the liquid heater includes a cover body covering the upper end of the glass cup body, the control module is arranged on the cover body, and the cover body and the glass cup body are electrically connected through an upper coupling component; and a power supply base installed at the lower end of the glass cup body, the power supply board is arranged on the power supply base, and the power supply base and the glass cup body are electrically connected through a lower coupling component.

[0026] For the liquid heater of the present application, first, the control module and the detection board are electrically connected through a wire harness, and then the detection board and the power supply board are electrically connected through the wire harness, so that the electrical signals on the control module are transmitted to the power supply board after passing through the detection board. Compared with the prior art in which the control module and the detection board are directly electrically connected to the power supply board, the detection board can be made to have the function of transmitting electrical signals, thus achieving the effect of integrating the detection board; at the same time, because the power supply board receives the electrical signals transmitted on the detection board and is not electrically connected to the control module, the number of interfaces on the power supply board is reduced, the overall layout of the power supply board is simplified, and the space occupied by the power supply board is reduced. At the same time, using the detection board as a transfer module for the control module to transmit signals can reduce the use of wire harnesses, thereby reducing the length of the wire harnesses used and making the arrangement of the wire harnesses inside the liquid heater more regular.

[0027] In the prior art, the control substrate is usually arranged on the power base, and the setting position is relatively single. When the control substrate is arranged on the power base, the user needs to have a relatively long viewing distance to see the control substrate. At the same time, when the user places the glass cup on the power base and then operates the control substrate, the finger needs to move a relatively long distance to operate the control substrate. Therefore, in order to facilitate the user to observe the control substrate at a close distance and also facilitate the user to operate the control substrate, the control substrate is electrically connected to the detection board separately. The control substrate that is electrically connected to the detection board separately can be arranged at the required position on the glass cup. The control substrate arranged on the glass cup is closer to the user. At the same time, because the control substrate is arranged on the glass cup, the finger only needs to move a relatively short distance to operate the control substrate. While improving the user's operation experience, it also provides conditions for diverse settings of the control substrate. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0042] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may also be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0044] Embodiment 1: As Figure 1 And Figure 2 Shown in the implementation manner, a liquid heater 100 includes a glass cup body 200. A detection board 201 is provided on the outer surface of the side wall of the glass cup body 200. Capacitor electrodes 202 are provided on the detection board 201. The liquid level height in the glass cup body 200 is detected through the capacitor electrodes 202. The liquid heater 100 further includes a power board and a control module 300 for controlling the liquid heater 100. The control module 300 is electrically connected to the power board through the detection board 201, so that the control module 300 transmits signals to the power board through the detection board 201.

[0045] In this embodiment, the capacitance of the capacitor plate 202 is detected to determine the liquid level height inside the glass cup body 200. When boiling the liquid inside the glass cup body 200, as the boiling time extends, the liquid level height inside the glass cup body 200 gradually rises. If the liquid level height rises significantly, it will overflow to the outside of the glass cup body 200, which not only poses a risk of scalding the user, but also causes dangers such as short circuits if the liquid comes into contact with the electronic control components of the liquid heater 100. For example, when boiling water, when approaching boiling and in the boiling state, the liquid will roll up and down, and at this time the liquid level height will rise to a certain extent. The rise in the liquid level height will change the capacitance value of the capacitor plate 202, so the capacitor plate 202 can determine the current liquid level height according to the fluctuation of the capacitance value.

[0046] Since the detection board 201 is arranged on the outer surface of the cup body, the cup body of the liquid heater 100 separates the two between the detection board 201 and the liquid. If the cup body is made of a metal material, the metal cup body will cause certain interference to the capacitance detection of the capacitor plate 202, thus affecting the detection of the liquid level height by the capacitor plate 202. To reduce the influence of the cup body on the detection of the capacitor plate 202, the cup body is made of glass. The main component of glass is silicon dioxide, and it contains less metal material. Therefore, it basically does not affect the detection of the liquid level height by the capacitor plate 202 through the change of the capacitance value.

[0047] The output end of the power supply board is used to receive various electrical signals transmitted by the detection board 201 and the control module 300. The output end of the power supply board is connected to various working components of the liquid heater 100. After processing various electrical signals, the power supply board judges the state of the liquid heater 100 and how various working components should work. For example, the output end of the power supply board can be connected to the heating tube. When the liquid level height inside the glass cup body 200 is greater than the preset value, the power supply board receives the electrical signal from the detection board 201 and processes it. The processed electrical signal is sent to the heating tube to reduce the heating power of the heating tube, thereby preventing the liquid inside the glass cup body 200 from exceeding the maximum preset value of the liquid level height due to receiving too much heat from the heating tube and then overflowing to the outside of the glass cup body 200.

[0048] The connection between the control module 300 and the detection board 201 can use the detection board 201 as a transmission medium. At this time, after the user performs corresponding operations on the control module 300, the control module 300 generates a transmission control signal. The transmission control signal is first sent to the wiring terminal of the detection board 201 through the wiring harness on the control template, and then the control signal is transmitted to the power supply board through the wiring harness on the wiring terminal. In this process, the detection board 201 only serves as a transmission medium and does not perform corresponding processing on the control signal. The processing of the control signal is performed on the control chip on the power supply board.

[0049] The detection board 201 can also be used as a processing and transmission medium. In this case, after the user performs corresponding operations on the control module 300, the control module 300 generates a transmission control signal. The transmission control signal first passes through the detection board 201. The detection board 201 processes and calculates the transmission control signal to obtain a third control signal (to distinguish it from the first control signal and the second control signal in the background art), and then transmits the third control signal to the power supply board through the feet and wire harnesses. In this process, the detection board 201 not only serves as a transmission medium but also as a signal processing device. The detection board 201 processes the control signal, which can reduce the computational load of the control chip on the power supply board, enabling the control chip to allocate more resources to more precisely and quickly control various working components of the liquid heater 100.

[0050] Among them, the capacitance signal generated by the capacitor electrode plate 202 can be transmitted to the power supply board together with the control signal on the same wiring terminal, or the capacitance signal and the control signal can be transmitted to the power supply board from different wiring terminals, without excessive limitation here.

[0051] In this way, the detection board 201 includes the function of processing the transmission control signal and the capacitance signal, and at the same time, the detection board 201 can also be used as a transmission medium to transmit the transmission control signal to the power supply board; while retaining the original signal processing function of the detection board 201, the detection board 201 can also be used as a transmission device to transmit the transmission control signal to the power supply board, and the detection board 201 does not perform corresponding processing on the transmission control signal during the transmission process. In this way, while increasing the transmission function of the detection board 201, the volume of the detection board 201 is not increased, enabling the detection board 201 to achieve an integrated effect.

[0052] Since the control button 301 is not electrically connected to the power supply board, the power supply board can reduce the interface for connecting to the control button 301, which can reduce the complexity of the power supply board design, simplify the layout of the power supply board, and reduce the occupied space of the power supply board.

[0053] At the same time, the control button 301 is first connected to the relatively close detection board 201, and then connected to the relatively far power supply board through the detection board 201, thus changing the connection of multiple long wire harnesses in the prior art into the connection of a single short-distance wire harness. This can not only ensure the regular connection of the wire harness but also keep the wire harness inside the liquid heater 100 all the time, reducing the risk of wire clamping between the wire harness and the liquid heater 100.

[0054] The liquid heater 100 includes small household appliances such as health kettles, soy milk makers, electric kettles, and wall breakers that can be used to heat liquids. The liquid can include pure water, such as the process of boiling water in an electric kettle; or the liquid can also include a mixture of certain ingredients added to pure water, such as adding water and beans in a soy milk maker to make soy milk.

[0055] Furthermore, in order to improve the integration of the detection board 201 and increase the functions of the detection board 201.

[0056] A processing chip 203 for processing the electrical signals of the control module 300 is provided on the detection board 201.

[0057] In order to reduce the processing volume of the control chip on the power board, so that the processing chip 203 can process other signals faster and improve the control accuracy of the liquid heater 100. A processing chip 203 can be provided on the detection board 201. The processing chip 203 preprocesses the transmitted control signal to obtain a judgment signal, and the judgment signal is transmitted to the control chip on the power board. The control chip only needs to perform a simple judgment process on the judgment signal and then can issue a first control signal to the liquid heater 100, and adjust different functions on the liquid heater 100 through the first control signal. At the same time, the processing chip 203 on the detection board 201 can also perform corresponding preprocessing on the capacitance signal generated by the capacitor electrode plate 202 to form a detection signal. The processing chip 203 will transmit the formed detection signal to the power board. The control chip on the power board will issue a second control signal to the liquid heater 100 after processing the detection signal, and adjust the heating method of the liquid heater 100 through the second control signal. The judgment signal and the detection signal can be transmitted to the power board through the same wire harness or through different wire harnesses.

[0058] Or, only increase the transmission function of the detection board 201, improve the integration effect of the detection board 201, and transmit the electrical signals generated by the control module 300 to the power board through the detection board 201.

[0059] Furthermore, in order to save the installation space of the liquid heater 100 and facilitate the installation of the control module 300 and the control button 301.

[0060] The control module 300 and the detection board 201 are integrated by plugging.

[0061] In this embodiment, the control module 300 and the detection board 201 form an integral whole through plugging. Usually, in normal use, the plugged control module 300 and detection board 201 will not separate. Only by applying a relatively large external force in the correct direction can the plugged control module 300 and detection board 201 be separated. Therefore, the control module 300 and the detection board 201 in the plugging manner can be recognized as an integral body.

[0062] Further, to facilitate the installation of the control module 300 and the detection board 201 into the liquid heater 100.

[0063] The control module 300 includes a control substrate 302 and control buttons 301, and the control substrate 302 is integrally formed with the detection board 201.

[0064] During the manufacturing process, the plate is integrally formed. Two areas are demarcated on the plate, namely the control substrate 302 and the detection side plate. Since the control substrate 302 and the detection board 201 are integrally formed, when placed inside the liquid heater 100, the overall plate can be more easily and quickly and accurately placed in the required position, facilitating the installer to fixedly install the plate.

[0065] On the control substrate 302, the control buttons 301 can be fixed on the control substrate 302 through processes such as wave soldering; similarly, on the detection board 201, the processing chip 203, etc. can also be fixed on the control substrate 302 through processes such as wave soldering.

[0066] Further, to provide good positioning for the detection board 201 while enabling the user to quickly locate the control buttons 301.

[0067] On the outer side of the glass cup body 200, there is an installation member 204 covering the outer side of the detection board 201, and the control buttons 301 are exposed outside the installation member 204.

[0068] The setting of the installation member 204 can prevent the detection board 201 from shifting during the installation process, and at the same time also plays a good positioning role for the installed detection board 201, preventing the detection board 201 from shifting during the use of the liquid heater 100, thereby affecting the detection board 201's judgment of the liquid level height.

[0069] Since the control buttons 301 generate and transmit electrical signals through capacitance changes or a membrane panel, in order to enable the user to quickly and accurately generate electrical signals when touching the control buttons 301, the control buttons 301 are exposed outside the installation member 204, so that the user can quickly and accurately find the position of the control buttons 301.

[0070] The liquid heater 100 includes a cover body 500 covering the upper end of the glass cup body 200, and a control module 300 is arranged on the cover body 500; and a power supply base 600 installed at the lower end of the glass cup body 200, and a power supply board is arranged on the power supply base 600; a detection board 201 is arranged on the glass cup body 200, and the detection board 201 is arranged between the control module 300 and the power supply board.

[0071] Among them, the liquid heater 100 may include a separately arranged glass cup body 200 and a power supply base 600. The glass cup body 200 mainly functions to hold liquid. An upper coupler is arranged on the glass cup body 200, and a lower coupler is arranged on the power supply base 600. After the upper coupler and the lower coupler are plugged into each other, the liquid heater 100 is connected to the mains through an external power supply, and then the liquid heater 100 can work normally. Or, the liquid heater 100 is integrally arranged. After being directly connected to the mains through an external power supply, the liquid heater 100 can work normally.

[0072] After the liquid heater 100 is normally powered on, the function of the liquid heater 100 is adjusted by controlling the control module 300. When the user stands and uses the liquid heater 100, the user will first see the cover body 500. Arranging the control module 300 on the cover body 500 can enable the user to more quickly locate the position of the control module 300.

[0073] Embodiment 2: As Figure 3 and Figure 4 shown in the embodiment, further, in order to improve the flexibility of the installation of the control button 301 and enable the control button 301 to be adaptively installed at the position required by the liquid heater 100.

[0074] The control module 300 includes a control substrate 302 provided with a control button 301, and the control substrate 302 is electrically connected to the detection board 201 separately.

[0075] The user changes different functions of the liquid heater 100 by operating the control substrate 302. For example, when the liquid heater 100 is a health kettle, the functions such as "boiling water", "cooking soup", and "cooking porridge" can be adjusted by operating the control substrate 302. Or the detection board 201 is used to detect the liquid level height in the glass cup body 200. When the liquid level height in the glass cup body 200 is greater than the preset value, the detection board 201 will send a signal to the control chip. After the control chip processes the signal, it will send a second control signal to the liquid heater 100. Through the second control signal, the power of the heating tube is reduced, or the operation of the heating tube is stopped to reduce the temperature of the liquid, thereby reducing the rising height of the liquid. During this process, it is necessary for the detection board 201 to monitor the liquid level height in the glass kettle body in real time to prevent the liquid in the glass kettle body from overflowing to the outside of the glass kettle body.

[0076] However, in some usage scenarios, there is no need to worry that the liquid level height will exceed the maximum preset value due to heating. For example, during the "boiling water" process, since there are no ingredients such as tremella and rice added in the glass kettle body, no foam layer will be generated (the virtual foam layer will rapidly increase the liquid height in the glass kettle body), reducing the possibility of the liquid level height exceeding the maximum preset value. During this process, it is not necessary for the detection board 201 to monitor the liquid level height in the glass kettle body in real time. At this time, it is necessary to close the real-time detection of the liquid level height by the detection board 201 through the control substrate 302 to reduce the working duration of the detection board 201 and extend the service life of the detection board 201.

[0077] In this way, the user can change the on / off state of the detection board 201 by operating the control substrate 302, or adjust various different functions of the liquid heater 100 by operating the control substrate 302. The control substrate 302 can be set at a suitable position on the liquid heater 100 according to different usage scenarios or installation convenience. For example, in order to reduce the length of the wire harness connecting the detection board 201 and the control substrate 302, the control substrate 302 can be set in the area near the lower part of the glass kettle body; or generally, when the user places the liquid heater 100 on the table, when the user stands in front of the table, the user will be at a relatively high position of the liquid heater 100. In order to enable the user to more conveniently switch the functions of the liquid heater 100 by controlling the control buttons 301, the control substrate 302 can be set in the area near the upper part of the glass kettle body; or when the user sits on a chair to operate the liquid heater 100, at this time the user is basically parallel to the glass cup body 200. When the control buttons 301 are set in the middle area of the glass cup body 200, it is convenient for the user to switch the functions of the liquid heater 100 by controlling the control buttons 301. In this way, the control substrate 302 can be flexibly set in any area of the glass cup body 200, so as to meet the needs of different usage scenarios, and the user can conveniently and comfortably operate the control substrate 302. Therefore, the control substrate 302 is electrically connected to the detection board 201 separately.

[0078] The control substrate 302 and the detection board 201 are electrically connected to each other. The electrical connection between the control substrate 302 and the detection board 201 not only includes that the detection board 201, as a transmission medium, transmits the electrical signals generated by the control substrate 302 to other components of the liquid heater 100; it can also include that the detection board 201, as a processing device, processes the electrical signals generated by the control substrate 302 and then transmits them to other components of the liquid heater 100.

[0079] Furthermore, in order to enable the user to conveniently operate the liquid heater 100 through the control buttons 301.

[0080] The liquid heater 100 includes a handle 400. The handle 400 includes a housing 401 and a receiving cavity 402 formed by surrounding the housing 401. The control substrate 302 is arranged in the receiving cavity 402, and a control area 403 is arranged on the housing 401. The control substrate 302 is correspondingly arranged with the control area 403.

[0081] The handle 400 of the liquid heater 100 is usually arranged on the glass cup body 200, and the user can move the liquid heater 100 by holding the handle 400.

[0082] The handle 400 is integrally formed with the housing or assembled in a split manner. The interior of the handle 400 is configured to be a hollow structure, so that the housing encloses to form a receiving cavity 402. In this way, the control substrate 302 can be completely hidden inside the receiving cavity 402 and not exposed outside the outer shell 401 of the handle 400. Thus, the control area 403 corresponding to the control substrate 302 can be set to be substantially on the same horizontal plane as the outer shell 401, and the control buttons 301 as a whole will not protrude or only slightly protrude from the outer shell 401. The control buttons 301 and the housing arranged on the same horizontal plane can facilitate the user to clean the handle 400, or enable the user to hold the handle 400 more comfortably when moving the liquid heater 100.

[0083] The control substrate 302 and the control area 403 are correspondingly arranged. When the user's finger approaches the control area 403, the capacitance value of the control substrate 302 will change, and then the control substrate 302 generates an electrical signal and transmits it to other components of the liquid heater 100 to achieve the control of other components.

[0084] Furthermore, in order to improve the user's control experience, when the user uses the control module 300, the control module 300 can produce a good feedback effect on the user.

[0085] The control module 300 includes a thin film panel provided with control buttons 301. One of the thin film panel and the detection board 201 is provided with a flexible cable, and the other is provided with a flexible cable socket 305, and the flexible cable is inserted into the flexible cable socket 305.

[0086] The control button 301 can also be configured as a thin film panel, and the thin film panel has a certain resilience. The thin film panel includes an elastic film, an insulating layer and a conductive contact. When the user presses the thin film panel, the elastic film on the thin film panel will bend downward, causing the conductive contacts originally isolated by the insulating layer to come into contact, forming a closed circuit. The closed circuit transmits the electrical signal to other components of the liquid heater 100; when the user releases the thin film button, the elastic film returns to its original state, and the conductive contacts separate to open the originally closed circuit to form an open circuit, and the control module 300 no longer transmits the electrical signal to other components of the liquid heater 100.

[0087] The thin film panel is connected to the detection board 201 through a flexible cable. One implementation method is to set a flexible cable on the thin film panel and a flexible cable socket 305 on the detection board 201; or to set a flexible cable socket 305 on the thin film panel and a flexible cable on the detection board 201. The method of assembling the thin film panel and the detection board 201 through the cooperation between the flexible cable and the flexible cable socket 305 not only can easily combine the thin film panel and the detection board 201 during the assembly process, but also if one of the thin film panel and the detection board 201 is damaged, the repair requirement can be met by only replacing one of them, reducing the repair cost of the liquid heater 100. The electrical signal generated by the thin film panel is transmitted to the detection board 201 through the flexible cable and the flexible cable socket 305.

[0088] Further, in order to make the wiring harness of the liquid heater 100 more regular.

[0089] The liquid heater 100 includes a handle 400. The handle 400 includes a receiving cavity 402. The thin film panel is bonded to the outer surface of the handle 400. The handle 400 is provided with a flexible cable hole for the flexible cable to pass through.

[0090] In order to facilitate the fixation between the thin film panel and the handle 400, the thin film panel is directly bonded to the outer surface of the handle 400, which is convenient for the thin film panel to be quickly installed on the handle 400 during the installation process. The thin film panel can be installed on the base of the handle 400 or on the cover of the handle 400. In order to facilitate the user to operate the thin film panel, the thin film panel is arranged on the cover of the handle 400.

[0091] In one embodiment, when a flexible cable is set on the thin film panel and a flexible cable socket is set on the detection board, the flexible cable can directly extend into the receiving cavity through the flexible cable hole provided on the handle, and then be connected to the flexible cable socket on the detection board; in one embodiment, when a flexible cable socket is set on the thin film panel and a flexible cable is set on the detection board, an avoidance position for avoiding the flexible cable socket is provided on the handle. After the flexible cable is connected to the flexible cable socket, it enters the receiving cavity through the flexible cable hole and then is connected to the detection board.

[0092] When the flexible cable passes through the inside of the receiving cavity 402, the flexible cable can be completely hidden inside the receiving cavity 402, so that the flexible cable is not completely exposed outside, playing a role in protecting the flexible cable.

[0093] In Embodiment 3: As Figure 5 shown in the implementation method, the handle 400 includes a connecting portion 404 for connecting the glass cup body 200, and a holding portion 405 connected to the connecting portion 404. The control button 301 is arranged on the connecting portion 404.

[0094] The detection board 201 includes a vertical board 205 extending along the direction of the glass body 200, and the control substrate 302 includes a horizontal board 306 extending towards the connecting part 404.

[0095] The horizontal board 306 and the vertical board 205 are separately arranged; alternatively, the horizontal board 306 and the vertical board 205 are integrally arranged.

[0096] The horizontal board 306 is fixedly connected to the control substrate 302. Clasps 406 are arranged on two side edges in the extending direction of the horizontal board 306. The clasp 406 includes a support arm 407 and a tongue 408. One end of the support arm 407 extends upward from the bottom wall of the connecting part 404, and the other end of the support arm 407 is provided with the tongue 408. The upward movement of the horizontal board 306 along the axial direction of the liquid heating container is restricted by the tongue 408. Through the arrangement of the clasps 406, the control substrate 302 can be better positioned and fixed.

[0097] Support columns 409 are arranged on the bottom wall of the connecting part 404. The support columns 409 are in contact with the horizontal board 306, and the downward movement of the horizontal board 306 along the axial direction of the liquid heating container is restricted by the support columns 409.

[0098] Embodiment 4: As Figure 6 In the embodiment shown, an anti-overflow indicator light 410 is arranged on the horizontal board 306. The anti-overflow indicator light 410 is arranged inside the control button 301; alternatively, the anti-overflow indicator light 410 is arranged side by side with the control button 301. Through the anti-overflow indicator light 410, the user can more intuitively observe whether the control button 301 is working.

[0099] The technical features of the above-described embodiments can be combined arbitrarily.
