Description

Technical Field

[0001] This application relates to the field of small household appliances, and particularly to a liquid heating container. Background Art

[0002] During the process of cooking or boiling food in a liquid heating container, some non - liquid - state water or other liquid substances will be generated during the cooking process. For example, during the process of making soy milk or boiling rice porridge, some soybeans or white rice are first added to the liquid, and heating devices such as heating tubes in the liquid heating container are used to heat the liquid - soybean mixture or liquid - rice mixture. During the cooking process, the liquid - soybean mixture or liquid - rice mixture will generate some slurry substances such as bubbles, foams, and froths.

[0003] In order to prevent the slurry substances from rising to a relatively high height and overflowing from the liquid heating container, a PCB detection board for non - contact detection is provided on the liquid heating container. The metal sheet on the PCB detection board and the slurry substances in the liquid heating container form a capacitor. When the height of the slurry substances in the liquid heating container increases, the capacitance of the capacitor changes, the capacitor charges and discharges, and a charge movement signal is generated on the PCB detection board. The PCB detection board transmits the charge movement signal to an electronic component, and the power of the heating tube is controlled by the electronic component.

[0004] In the prior art, in order to enable the PCB detection board to always face the glass kettle body directly, the PCB detection board is usually placed between the handle and the glass kettle body. As disclosed in patent numbers CN106108646A, CN201720159218.0, CN201721038797.X, etc. (not listing more prior arts here), the disclosed technical solutions all adopt setting the PCB detection board on the outer wall of the glass kettle body. The PCB detection board is attached to the outer wall of the glass kettle body, and a handle shell is provided on the handle. The handle shell includes an arc - shaped cavity that matches and wraps the handle and an installation groove for embedding the PCB detection board.

[0005] During the installation process, through the radial force of the handle on the PCB detection board, the PCB detection board is fixed on the outer wall of the glass kettle body. First, during the installation process, the handle is usually opaque. During the process of fixing the PCB detection board by the handle, the operator cannot monitor the positional relationship between the PCB detection board and the glass kettle body in real time. In this way, the PCB detection board will be misaligned with the glass kettle body during the installation process. After the PCB detection board is installed and fixed, it cannot be fixed along the extension direction of the glass kettle body, but will be inclined or have a gap with the glass kettle body. Therefore, there is a technical problem that the positioning of the PCB detection board is not accurate enough during the installation and fixing process. And the installation process of fixing the PCB detection board on the glass kettle body by the handle is relatively complex, which affects the installation efficiency.

[0006] In addition, in the patent No. CN202222795278.5, a solution of splitting the handle into a handle holder and a handle body is disclosed. Even though the handle is split into two parts, the core idea is still that the handle body presses the handle holder and the temperature measuring element against the outer wall of the kettle body, and the installation is still relatively unstable and complex. Utility Model Content

[0007] The present application discloses a liquid heating container, thus solving the technical problems of inaccurate positioning and complex installation of the PCB detection board in the prior art during the installation process.

[0008] A liquid heating container of the present application includes a glass kettle body and a handle. An air-permeable bracket extending in the height direction is provided on the outer wall of the glass kettle body, and the height of the air-permeable bracket is greater than the width of the air-permeable bracket;

[0009] A PCB detection board for non-contact detection is provided between the air-permeable bracket and the glass kettle body. A groove is provided on the side of the air-permeable bracket facing the glass kettle body. The PCB detection board is placed in the groove, and the thickness of the PCB detection board is not greater than the depth of the groove. The handle is provided at a position corresponding to the air-permeable bracket;

[0010] The air-permeable bracket includes two first brackets extending in the height direction and connected to each other, and a limiting rib provided on the air-permeable bracket to limit the radial movement of the PCB detection board along the glass kettle body. The PCB detection board is located between the two first brackets;

[0011] In the circumferential direction, the width of the PCB detection board is smaller than the width of the air-permeable bracket, so that both sides of the PCB detection board respectively have a first gap that radially penetrates the two first brackets;

[0012] Fixing glue is provided in the first gap, and the PCB detection board and the air-permeable bracket are adhered to the outer wall of the glass kettle body by the fixing glue.

[0017] Optionally, the part of the hollowed-out bracket facing the glass kettle body and adapted to the arc-shaped outer wall is an arc-shaped surface.

[0018] Optionally, both ends of the two first brackets are respectively connected by the second bracket, the first bracket and the second bracket enclose a frame, and the PCB detection board is restricted within the frame.

[0020] Optionally, a first isolation rib extending from the side wall of the first bracket towards the center of the hollowed-out bracket is formed. Along the circumferential direction of the glass kettle body, the first isolation rib isolates the side surface of the PCB detection board and the side surface of the first bracket, so as to form the first gap between the PCB detection board and the first bracket.

[0021] To further strengthen the technical problem of sealing the electronic components,

[0022] Optionally, electronic components are arranged below the PCB detection board opposite to the glass kettle body, the hollowed-out bracket forms a hollow and closed anti-overflow frame, and the anti-overflow frame is arranged around the outer edge of the electronic components.

[0023] To further strengthen the technical problem of sealing the PCB detection board,

[0024] Optionally, the fixing glue is filled into the hollowed-out bracket so that the fixing glue completely covers the side of the PCB detection board opposite to the glass kettle body.

[0025] To further strengthen the technical problem of fixed installation in the width direction of the PCB detection board,

[0026] Optionally, a second isolation rib extending from the side wall of the second bracket towards the center of the hollowed-out bracket is formed. Along the height direction of the glass kettle body, the second isolation rib isolates the end face of the PCB detection board and the side surface of the second bracket, so as to form a third gap between the PCB detection board and the second bracket, and the fixing glue is set in the third gap.

[0027] Optionally, one end of the PCB detection board away from the electronic component passes through the anti-overflow frame and moves upward above the hollowed-out bracket, so that the entire PCB detection board extends into the groove. Conductive wires are provided on the electronic component, and the conductive wires extend out of the anti-overflow frame and extend downward below the glass kettle body.

[0028] To further strengthen the technical problem of the self-strength of the hollowed-out bracket,

[0029] Optionally, the limiting ribs are arranged above the side of the PCB detection board facing away from the glass kettle body, and the limiting ribs criss-cross to divide the hollowed-out bracket into a plurality of potting grids.

[0030] Optionally, the limiting ribs are arranged on the side wall of the first bracket and extend towards the hollowed-out area of the hollowed-out bracket;

[0031] Alternatively, the limiting ribs extend in the transverse direction to connect two first brackets.

[0032] Optionally, the limiting ribs extend from the side wall of the second bracket towards the hollowed-out area of the hollowed-out bracket;

[0035] Optionally, the limiting ribs connect two first brackets, and the first isolation rib is located on the side of the limiting rib facing the glass kettle body and is connected to the limiting rib.

[0036] Optionally, a connecting glue matching the arc-shaped outer wall is pasted on the arc-shaped surface.

[0037] In a liquid heating container of the present application, by using a hollowed-out bracket to limit the radial movement of the PCB detection board along the glass kettle body, the PCB detection board can be reliably attached to the outer wall of the glass kettle body, improving the detection accuracy and consistency of the PCB detection board during the operation of the liquid heating container. Moreover, the first bracket and the PCB detection board are fixed to the outer wall of the glass kettle body by the fixing glue in the first gap, greatly simplifying the installation difficulty of the PCB detection board and also improving the installation accuracy of the PCB detection board; in particular, when the PCB detection board is installed using a hollowed-out bracket, the installation of the PCB detection board is in a completely visible manner. In addition to realizing the pasting and fixing of the hollowed-out bracket and the outer wall of the glass kettle body, the fixing glue can also utilize the gap between the hollowed-out bracket and the PCB detection board to realize the pasting and fixing of the PCB detection board, the hollowed-out bracket, and the outer wall of the glass kettle body, greatly improving the fixing strength of the PCB detection board.

[0038] The formed second gap makes the connection between the glass kettle body and the PCB detection board more reliable. In particular, when the depth of the groove is greater than the thickness of the PCB detection board and the arc-shaped outer wall and the hollowed-out bracket clamp the PCB detection board, the arc-shaped outer wall protrudes towards the inside of the groove, enabling better fitting between the arc-shaped outer wall and the middle part of the PCB detection board, thus better solving the problem of limiting the PCB detection board, that is, there is no need to rely on an external mold to limit the PCB detection board, and the detection accuracy of the PCB detection board is also improved.

[0039] By arranging the first isolation rib on the hollowed-out bracket, the first isolation rib fits with the side of the PCB detection board, directly restricting the circumferential movement of the detection board along the glass kettle body. In this way, the width of the first gap can be relatively fixed and will not change due to external interference, ensuring the connection strength and strength consistency among the PCB detection board, the hollowed-out bracket, and the glass kettle body.

[0040] When the second bracket is also connected to both ends of the first bracket, the first bracket and the second bracket together form the edge of the hollowed-out bracket, that is, a frame structure is formed by enclosing two first brackets and two second brackets, and the PCB detection board is restricted within the frame. The two first brackets limit the PCB detection board in the circumferential direction along the glass kettle body, and the two second brackets limit the PCB detection board in the height direction along the glass kettle body, which is beneficial to improving the installation efficiency of the PCB detection board.

[0065] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to 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.

[0066] 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.

[0067] 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 in this specification 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.

[0068] In order to prevent the height of the slurry material from rising too high during cooking and spilling outside the liquid heating container or entering the handle, a PCB detection board capable of non-contact detection is provided on the liquid heating container. A detection area is provided on one side of the PCB detection board, and the surface with the detection area is correspondingly arranged with the glass kettle body. Thus, changes in the liquid height or slurry material height in the glass kettle body can be monitored through the detection area, and the working state of the liquid heating container can be adjusted accordingly based on the monitored height. The detection area can be divided into a water level detection area or an anti-overflow detection area. Either one can be selected, or both can exist at the same time. When both exist at the same time, the anti-overflow detection area is located above the water level detection area.

[0069] For example: The height of the slurry substance is detected by the PCB detection board. When the height of the slurry substance is greater than the preset height, the PCB detection board will send a control signal to lower the temperature of the heating tube, so that the height of the slurry substance drops towards the safe height. During the descent, the PCB detection board continuously monitors the height of the slurry substance. When the height of the slurry substance drops to the safe height, the PCB detection board will send a control signal again to increase the temperature of the heating tube and reheat the food, and the height of the slurry substance begins to rise. This process repeats until the cooking is completed.

[0070] The PCB detection board 2 includes a front surface close to the glass kettle body 1 and a rear surface disposed opposite to the front surface. A metal sheet for signal detection is provided on the front surface to form a capacitive detection electrode. A control chip and a wiring port are provided on the rear surface of the PCB detection board 2, and the data of the capacitive detection electrode is transmitted to the control chip for processing.

[0071] If the rising height of the slurry substance is relatively high or the signal detected by the PCB detection board is delayed, the slurry substance is likely to overflow from the through hole where the upper part of the kettle body of the liquid heating container communicates with the outside to the outside of the liquid heating container, making it easy for consumers to touch the slurry substance when lifting the liquid heating container, causing burns to consumers or making the part of the liquid heating container held by consumers have viscous substances. When consumers hold the liquid heating container, the viscous substances will stick to the hands of consumers, affecting the use experience of consumers.

[0072] Therefore, if the PCB detection board 2 is inclined in height relative to the glass kettle body 1, loose in installation, or inaccurate in positioning height due to improper installation, at this time, the liquid level height with fluctuating capacitance values detected by the capacitive detection electrode is inconsistent with the actual liquid level height to be detected in the glass kettle body 1, which will reduce the detection accuracy of the PCB detection board 2. Specifically, it stops working before reaching the actual required detection height; or, it is still working when reaching the actual required detection height, and even causes overflow. Therefore, during the installation process, it is necessary to prevent the PCB detection board 2 from being unreliable in installation due to uneven force during the installation process or the inability to fix the PCB detection board 2 well.

[0073] During use, food, liquid, etc. will be added inside the glass kettle body 1, which will increase the weight of the glass kettle body 1. The handle 4 is used to lift the glass kettle body 1. If the handle 4 is set in a hollow shape, the strength of the handle 4 will be reduced. Thus, during the process of lifting the glass kettle body 1 through the handle 4, it may not be possible to lift the glass kettle body 1 due to insufficient strength of the handle 4, and in severe cases, the handle 4 may be broken and damaged. Therefore, generally, the handle will not be made into a hollow structure. If the handle is used to fix the PCB detection board, it will also increase the difficulty of installation.

[0074] The liquid heating container of the present application may include products such as a health kettle, an electric kettle, a soymilk maker, and a wall breaker.

[0075] A liquid heating container of the present application includes a glass kettle body 1. On the outer side of the glass kettle body 1, there is a hollowed-out bracket 3 extending in the height direction. The height of the hollowed-out bracket 3 is greater than the width of the hollowed-out bracket 3. The hollowed-out bracket 3 includes two first brackets 31 extending in the height direction and connected to each other, and a limiting rib 39 provided on the hollowed-out bracket 3 to limit the radial movement of the PCB detection board 2 towards the glass kettle body 1. The PCB detection board 2 is located between the two first brackets 31. A PCB detection board 2 for non-contact detection is provided between the hollowed-out bracket 3 and the glass kettle body 1. On the side of the hollowed-out bracket 3 facing the glass kettle body 1, there is a groove 38. The PCB detection board 2 is placed into the groove 38. The hollowed-out bracket 3 restricts the radial movement of the PCB detection board 2 along the glass kettle body 1. The thickness of the PCB detection board 2 is not greater than the depth of the groove 38. In the circumferential direction, that is, along the circumferential direction of the glass kettle body 1, the width of the PCB detection board 2 is less than the width of the hollowed-out bracket 3, so that both sides of the PCB detection board 2 have a first gap 51 that radially penetrates with the first bracket. A fixing glue is provided in the first gap 51. The PCB detection board 2 and the hollowed-out bracket 3 are adhered to the outer side of the glass kettle body 1 by the fixing glue.

[0076] In order to hold more liquid, the glass kettle body 1 is usually in a long cylindrical shape. And in order to meet the requirements of improving the accuracy of anti-overflow detection and / or water level detection, the PCB detection board 2 is usually set in a long strip shape with an appropriate width. At this time, the long strip-shaped PCB detection board 2 can not only well cover the height of the liquid in the glass kettle body 1, enabling the PCB detection board 2 to monitor the liquid level height in real time, but also because the width of the PCB detection board 2 is appropriate, it can simultaneously meet the accuracy requirements of anti-overflow detection and / or water level detection. For the above reasons, in order to adapt to the general shape of the above-mentioned PCB detection board 2, the hollowed-out bracket 3 extends along the height direction of the glass kettle body 1, and the height of the hollowed-out bracket 3 is greater than the width of the hollowed-out bracket 3. Of course, those skilled in the art can think that according to specific detection requirements, the size of the detection board can be changed, and the size of the hollowed-out bracket can also be changed.

[0077] In Figures 1 to 13 the Figure 21 embodiment shown in FIGS. and, the hollowed-out bracket 3 includes two first brackets 31 which are arranged at its edges and extend in the height direction and are connected to each other. The PCB detection board 2 is located between the two first brackets 31. A limiting rib 39 for restricting the radial movement of the PCB detection board 2 along the glass kettle body 1 is arranged on the hollowed-out bracket 3. It can be understood that the limiting rib 39 functions to prevent the PCB detection board 2 from detaching from the glass kettle body 1. In this embodiment, the limiting rib 39 is set as a vertical rib 332 and three horizontal ribs 331. Among them, the horizontal rib 331 also functions to connect the two first brackets 31. Of course, the number of the vertical rib 332 and the horizontal rib 331 can be selected according to specific requirements, or the way of only setting the horizontal rib 331 or only setting the vertical rib 332 can also be selected. Further elaboration will be provided in the subsequent description of this patent specification.

[0078] In this embodiment, in order to fix the PCB detection board 2 and the two first brackets 31 to the glass kettle body, in the circumferential direction of the glass kettle body 1, the width of the PCB detection board 2 can be set to be smaller than the width of the hollowed-out bracket 3, so that there are first gaps 51 which are radially penetrated on both sides of the PCB detection board 2, that is, the width of the PCB detection board 2 is set to be smaller than the distance between the two first brackets 31. Fixing glue is arranged in the first gaps 51, and then the PCB detection board 2 and the hollowed-out bracket 3 are pasted together by the fixing glue, realizing the strengthened fixation of the PCB detection board 2 and the first bracket 31. It can be understood that since the first gaps 51 are arranged in a penetrating manner, the fixing glue can be directly injected into the first gaps 51 from the side of the hollowed-out bracket 3 facing away from the glass kettle body 1, and the fixing glue in the first gaps 51 is directly in contact (pasted) with the side surface of the first bracket 31, the side surface of the PCB detection board 2 and the outer wall of the glass kettle body 1, so as to achieve the purpose of pasting the PCB detection board 2 and the first bracket 31 together on the outer wall of the glass kettle body 1. Specifically, when filling the fixing glue into the first gaps 51, in the circumferential direction, the fixing glue connects the PCB detection board 2 and the hollowed-out bracket 3, and in the radial direction, the fixing glue is connected to the glass kettle body 1, achieving the purpose of connecting the PCB detection board 2, the hollowed-out bracket 3 and the glass kettle body 1 into an integral body, that is, forming a cup body assembly. In the production process of the liquid heating container, forming the cup body assembly in advance is beneficial to clear processes and improve production efficiency.

[0079] On the one hand, the width of the PCB detection board 2 is smaller than that of the hollowed-out bracket 3, so that there can be a gap between the PCB detection board 2 and the hollowed-out bracket 3; on the other hand, the PCB detection board 2 can be limited by the mold in the process or by the hollowed-out bracket 3, so that there are first gaps 51 that penetrate radially between the two sides of the PCB detection board 2 and the two first brackets 31 of the hollowed-out bracket 3 respectively, that is, there are first gaps 51 on both the left and right sides. By using the method of applying glue to both of the first gaps 51 on both sides, both sides of the long hollowed-out bracket 3 and the long PCB detection board 2 can be fixed to the glass kettle body 1 through the fixing glue, and the first gap 51 is located in the longitudinal direction of the hollowed-out bracket 3, which is more conducive to extending the length of the first gap 51 and improving the reliability of the connection.

[0080] The first gap 51 can be the gap between the PCB detection board 2 and the hollowed-out bracket 3 manually adjusted by the installer after installing the PCB detection board 2 into the groove 38.

[0081] If the generation of the first gap 51 requires manual adjustment by the installer, this method is relatively cumbersome, or because the weight of the PCB detection board 2 itself is relatively light, only a small force is required during the process of pouring the fixing glue to cause the PCB detection board 2 to shift, which will cause the original two first gaps 51 to become one due to the external force, resulting in connection only on one side and insufficient connection strength.

[0082] In order to form a stable first gap 51, in the circumferential direction of the kettle body, the width of the PCB detection board 2 is set to be smaller than that of the hollowed-out bracket 3, and a first isolation rib 34 is provided on the first bracket 31. Specifically, the first isolation rib 34 extends from the side wall of the first bracket 31 towards the center of the hollowed-out bracket 3. Along the circumferential direction of the glass kettle body 1, the first isolation rib 34 isolates the side surface of the PCB detection board 2 and the side surface of the first bracket 31, so as to form a first gap 51 between the PCB detection board 2 and the first bracket 31. By providing the first isolation rib 34 on the hollowed-out bracket 3, the first isolation rib 34 fits against the side edge of the PCB detection board 2, directly restricting the circumferential movement of the detection board along the glass kettle body 1, so that the width of the first gap 51 can be relatively fixed and will not be changed due to external interference. Among them, the length of the first isolation rib 34 is generally set to 1-5 mm, the thickness is generally set to 1-5 mm, and the height is generally set to 1-5 mm. In this embodiment, the first isolation rib 34 is provided on the hollowed-out bracket 3 by an integral molding method, and three first isolation ribs 34 are provided on each first bracket 31. The middle first isolation rib 34 is provided on the transverse rib 331. At this time, as Figure 13As shown, the first isolation rib 34 divides the first gap 51 into multiple segments. Of course, those skilled in the art can understand that there may or may not be a gap between the first isolation rib 34 and the glass kettle body 1; the number of the first isolation ribs 34 arranged on the first bracket 31, whether it is arranged on the cross rib 331, whether it is symmetric, etc. can also be selected according to specific requirements, and there will be further elaboration in the subsequent description of this patent specification. In addition, the way that the first isolation rib 34 and the first bracket 31 are integrally formed is also relatively convenient and fast. Of course, based on the utility model intention of this patent, the above-mentioned implementation manners in which the first isolation rib 34 and the first bracket 31 are connected in a split manner such as adhesion should also be within the scope of protection claimed in this patent.

[0083] Adopting the technical solution of arranging the first isolation rib 34 above, when setting the fixing glue in the first gap 51, the amount of the fixing glue can also be accurately determined, and the connection strength between the PCB detection board 2 and the first bracket 31 on the glass kettle body 1 can be improved. In order to ensure the consistency of the glue amount in the first gap 51 and improve the uniformity of the connection strength, the width of the first gap 51 can be kept consistent by arranging the first isolation ribs 34 of the same size. Of course, those skilled in the art can adjust the size of the first isolation rib 34 or the width of the first gap 51 according to requirements. Of course, those skilled in the art can also think that the first gap 51 in this embodiment can also be set on one side, and the other side is sealed by other means.

[0084] The first isolation rib 34 is set in a suspended state (specifically, the positions marked with the two reference numerals 34 can be referred to) Figure 17 The first isolation rib 34 divides the first gap 51 into multiple segments. The number of the first isolation ribs on the two first brackets can be the same or different, or they can be arranged oppositely or staggeredly. In order to facilitate mold release and strengthen the strength of the first isolation rib, the limiting rib 39 connects the two first brackets 31, and the first isolation rib 34 is located on the side of the limiting rib 39 facing the glass kettle body 1 and is connected to the limiting rib 39.

[0085] In this embodiment, second brackets 32 are also connected to both ends of the first bracket 31. The first bracket 31 and the second brackets 32 together form the edge of the hollow bracket 3, that is, a frame structure is formed by enclosing two first brackets 31 and two second brackets 32, and the PCB detection board 2 is restricted within the frame. The two first brackets 31 limit the PCB detection board 2 in the circumferential direction (along the circumferential direction of the glass kettle body 1), and the two second brackets 32 limit the PCB detection board 2 in the axial direction (along the height direction of the glass kettle body 1), which is beneficial to improving the installation efficiency of the PCB detection board 2.

[0086] At this time, it is found during the assembly process that since there is no limiting structure at the upper and lower ends of the PCB detection board 2, the PCB detection board 2 is very easy to slip out from both ends of the hollowed-out bracket. To solve the above problems, on the one hand, the glass kettle body 1 can be placed horizontally when filling the fixing glue; on the other hand, a limiting structure can be set at the opening to limit the movement of the PCB detection board 2. Specifically, as Figure 11 shown, by setting second brackets at both ends of the first bracket to limit the axial movement of the PCB detection board 2 along the glass kettle body 1.

[0087] It can be understood that a third gap 53 can also be set between the second bracket 32 and the PCB detection board 2, and fixing glue can be set in the third gap 53 for bonding the second bracket 32 and the PCB detection board 2. Correspondingly, a second isolation rib 35 extending from the side wall of the second bracket 32 towards the center of the hollowed-out bracket 3 is formed. Along the height direction of the glass kettle body 1, the second isolation rib 35 isolates the end face of the PCB detection board 2 and the side face of the second bracket 32, so as to form a third gap 53 between the PCB detection board 2 and the second bracket 32, and the fixing glue is set in the third gap 53. As mentioned above, the fixing glue in the third gap 53 directly contacts (adheres to) the side face of the second bracket 32, the side face of the detection board, and the outer wall of the glass kettle body 1. The second isolation rib 35 is similar to the first isolation rib 34, and the third gap 53 is similar to the first gap 51, so it will not be elaborated here.

[0088] When pouring the fixing glue, the fixing glue flows into the third gap 53. In the third gap 53, the fixing glue fixes the edges in the width direction of the PCB detection board 2 and the edges in the width direction of the hollowed-out bracket 3; flowing along the third gap 53 into the groove 38, the fixing glue flows onto the edges in the width direction of the side of the PCB detection board 2 close to the glass kettle body 1 and the edges in the width direction of the side of the hollowed-out bracket 3 close to the glass kettle body 1, thereby strengthening the fixing strength between the PCB detection board 2 and the glass kettle body 1, and strengthening the fixing strength between the hollowed-out bracket 3 and the glass kettle body 1. Through the third gap 53, the amount of fixing glue entering between the PCB detection board 2 and the glass kettle body 1 can be increased, strengthening the fixing of the PCB detection board 2 and preventing the PCB detection board 2 from shaking in the hollowed-out bracket 3.

[0089] Those skilled in the art can also think that the second bracket 32 can be set only at one end of the two first brackets 31 (as Figure 15 and Figure 17 shown), of course, the second bracket 32 can also not be set (as Figure 14 and Figure 16 shown), and specific selection is made according to actual requirements. Further elaboration will be provided in the subsequent description of this patent specification.

[0090] In this embodiment, the fixing glue can also be filled into the hollowed-out bracket 3, so that the fixing glue completely covers the side of the PCB detection board 2 facing away from the glass kettle body 1, and the PCB detection board 2 and the limiting rib 39 in this embodiment are also connected by the fixing glue.

[0091] Specifically, a vertical rib 332 and three horizontal ribs 331 divide the hollowed-out bracket 3 into a plurality of glue filling grids 36 in a criss-cross manner, and then the fixing glue is filled by pouring. The PCB detection board 2 is also connected to the vertical rib 332 and the three horizontal ribs 331 by the fixing glue. In this way, the entire circumference of the PCB detection board 2 can be sealed by the fixing glue, so that it is difficult for liquid or water vapor to enter the side of the PCB detection board 2 facing the glass kettle body 1 along the circumference of the PCB detection board 2.

[0092] The applicant of this patent found that it is still difficult to install the hollowed-out bracket 3 to cover the PCB detection board 2. A groove 38 is provided on the side of the hollowed-out bracket 3 facing the glass kettle body 1. Specifically, it can be understood that in this embodiment, the sides of the horizontal rib 331 and the vertical rib 332 facing the glass kettle body 1 cooperate with the sides of the two first brackets 31 and the two second brackets 32 to form the groove 38. During the installation of the PCB detection board 2, the PCB detection board 2 is placed into the groove 38, and the hollowed-out bracket 3 restricts the radial movement of the PCB detection board 2 along the glass kettle body 1, that is, the blocking effect of the limiting rib 39 prevents the PCB detection board 2 from detaching from the hollowed-out bracket 3. Based on the utility model intention of this patent, the formation of the groove 38 can be selected according to the specific structure of the hollowed-out bracket 3. For example, the sides of the two first brackets 31 and a limiting rib 39 (a horizontal rib 331 or a vertical rib 332) can also form the groove 38. Further elaboration will be provided in the subsequent description of this patent specification.

[0093] Adopting the above technical solution, during the installation of the PCB detection board 2, by placing the PCB detection board 2 into the groove 38 of the hollowed-out bracket 3, and the thickness of the PCB detection board 2 is not greater than the depth of the groove 38, this can make the PCB detection board 2 completely extend into the groove 38. At the same time, due to the blocking effect of the hollowed-out bracket 3, it prevents the PCB detection board 2 from detaching from the hollowed-out bracket 3. During installation, first, the PCB detection board 2 is extended into the groove 38 of the hollowed-out bracket 3, and then the side of the groove 38 in the hollowed-out bracket 3 is placed facing the glass kettle body 1. Specifically, the side of the limiting rib 39 facing the glass kettle body cooperates with the sides of the two first brackets 31 to form the groove.

[0094] During installation, first insert the PCB detection board 2 into the groove 38 of the hollowed-out bracket 3, and then place the side of the groove 38 in the hollowed-out bracket 3 facing the glass kettle body 1. At this time, a receiving cavity is formed between the outer wall of the hollowed-out bracket 3 and the outer wall of the glass kettle body 1 (it can also be understood that the groove 38 and the outer wall of the glass kettle body 1 form the receiving cavity). The PCB detection board 2 is well restricted within this receiving cavity. That is, the limiting rib 39 restricts the movement of the PCB detection board 2 in the radial direction of the glass kettle body 1, the first bracket 31 restricts the movement of the PCB detection board 2 in the circumferential direction of the glass kettle body 1, and the second bracket 32 restricts the movement of the PCB detection board 2 in the height direction of the glass kettle body 1.

[0095] The applicant has found that when too much fixing glue is poured, the fixing glue is likely to overflow from the part where two components are in contact to the outside of the hollowed-out bracket 3 and onto the glass kettle body 1. Since the overflowed fixing glue is not completely dried, during the installation process, other components may come into contact with the overflowed fixing glue and may adhere to the glass kettle body 1. Moreover, the fixing glue overflowed onto the glass kettle body 1 is also difficult to clean, affecting the overall appearance of the liquid heating container. When the thickness of the PCB detection board 2 is not greater than the depth of the groove 38, in addition to improving the assembly convenience before placement, that is, the PCB detection board 2 can be completely embedded into the groove 38. In this way, the PCB detection board 2 is not easily detached from the hollowed-out bracket 3, and it can also make the sides of the first bracket 31 and the second bracket 32 facing the glass kettle body 1 closer to the outer wall of the glass kettle body 1, which can better solve the problem that the fixing glue in the first gap 51 overflows from the positions between the first bracket 31 and the glass kettle body 1 and between the second bracket 32 and the glass kettle body 1.

[0096] Furthermore, in order to reduce the overflow of the poured fixing glue, when the outer wall of the glass kettle body 1 is set as the arc-shaped outer wall 11, in order to make the cooperation between the hollowed-out bracket 3 and the arc-shaped outer wall 11 closer and reduce the possibility of the fixing glue overflowing from the position between the edge of the hollowed-out bracket 3 and the glass kettle body 1, the part of the hollowed-out bracket 3 facing the glass kettle body 1 and adapted to the arc-shaped outer wall 11 is the arc-shaped surface 311. At this time, when the hollowed-out bracket 3 is pressed tightly on the glass kettle body 1, the arc-shaped surface 311 and the arc-shaped outer wall 11 are more closely matched, achieving the purpose of having no gap or a gap that is not sufficient to allow the glue to overflow to the outside of the hollowed-out bracket 3. That is, the thickness of the PCB detection board 2 is not greater than the depth of the groove 38. Insert the PCB detection board 2 into the hollowed-out bracket 3, and the side of the PCB detection board 2 facing the glass kettle body 1 does not protrude from the arc-shaped surface 311 of the hollowed-out bracket 3.

[0097] It can be understood that in order to increase the contact area between the PCB detection board 2 and the outer wall of the glass kettle body 1, it is generally conceivable that the mating surfaces of the glass kettle body 1 and the PCB detection board 2 have the same shape, such as a flat surface matching a flat surface, and a curved surface matching a curved surface. In products, especially the glass kettle body 1 of health care kettles, it is preferably possible to use relatively thin glass. It is difficult to achieve a flat surface by cutting it thinner (it is easy to break), and even if it can be achieved by means of recesses, it will affect the appearance. The applicant has found that when the solution of this patent is adopted, even when the mating surfaces of the glass kettle body 1 and the PCB detection board 2 are not of the same shape, better effects can be obtained. Specifically, the glass kettle body 1 includes an arc-shaped outer wall 11, and the PCB detection board 2 is installed on the arc-shaped outer wall 11. The surface of the PCB detection board 2 facing the arc-shaped outer wall 11 is a flat surface, and there is a second gap 52 between the two side edges of the flat surface and the glass kettle body 1 to provide a fixing glue in the second gap 52. When the above solution is adopted, on the one hand, the second gap 52 formed makes the connection between the glass kettle body 1 and the PCB detection board 2 more reliable. On the other hand, when the arc-shaped outer wall 11 and the hollowed-out bracket 3 clamp the PCB detection board 2, the problem of limiting the PCB detection board 2 is better solved, making the limiting of the PCB detection board 2 more convenient, that is, there is no need to use an external mold to limit the PCB detection board 2 (the limiting method will be described below in combination with the structure of the hollowed-out bracket 3).

[0098] Furthermore, the applicant has found that when the thickness of the PCB detection board 2 is not greater than the depth of the groove 38, in addition to the above-mentioned limiting effect when the hollowed-out bracket 3 is placed on the glass kettle body 1, it can also play a role in improving the assembly convenience before placement, that is, the PCB detection board 2 can be completely embedded in the groove 38, so that the PCB detection board 2 is not easily detached from the hollowed-out bracket 3.

[0099] In the above embodiment, the depth of the groove 38 is preferably between 1 and 1.8 mm, and the thickness of the PCB detection board 2 is preferably between 0.8 and 1.2 mm.

[0100] In the above embodiment, during the installation of the PCB detection board 2, after the liquid heating container is laid down, the PCB detection board 2 is inserted into the groove 38, and then the hollowed-out bracket 3 and the PCB detection board 2 are simultaneously placed on the glass kettle body 1, and then the hollowed-out bracket 3 and the PCB detection board 2 are fixed on the glass kettle body 1 by pouring the fixing glue. If the strength of the hollowed-out bracket 3 is small, it cannot fix the PCB detection board 2 well, and at the same time, the hollowed-out bracket 3 is prone to deformation during the installation process. To improve the strength of the hollowed-out bracket 3, the limiting ribs 39 are arranged above the side of the PCB detection board 2 facing away from the glass kettle body 1, and the limiting ribs 39 are arranged in a criss-cross pattern to divide the hollowed-out bracket 3 into a plurality of glue pouring grids 36.

[0101] Since the central area of the hollow support 3 is set as a hollow structure, the strength of the central area of the hollow support 3 is the weakest. In order to improve the strength of the central area of the hollow support 3, the limiting ribs 39 are arranged in a crisscross manner in the central area of the hollow support 3 to improve the overall strength of the hollow support 3.

[0102] In the above embodiment, those skilled in the art found during the assembly process that although the cooperation between the arc-shaped outer wall 11 and the arc surface 311 is closer, due to the fact that the glass kettle body 1 is formed by blowing and there are certain deviations in the manufacturing process, after the PCB detection board 2 extends into the hollow support 3 and is placed on the horizontally placed glass kettle body 1, and then the fixing glue is poured into the hollow support 3, there is a possibility that the two cannot be closely matched. Then, it is possible for the fixing glue to enter between the first support 31 and the glass kettle body 1, and even cause local overflow. In order to more conveniently position the hollow support 3 on the outer wall of the glass kettle body 1, a conforming connecting glue, such as 3M glue, double-sided glue, etc., can be pre-pasted on the arc surface 311, and the hollow support 3 is directly adhered to the glass kettle body 1 through the connecting glue to play a positioning role for the hollow support 3, and this kind of connecting glue will not flow randomly and affect the appearance.

[0103] Specifically, after the PCB detection board 2 extends into the hollow support 3, the hollow support 3 is first fixed on the glass kettle body 1 through the connecting glue. After the hollow support 3 is fixed, the fixing glue is then poured into the hollow support 3. The hollow support 3 can either achieve a tight fit with the glass kettle body 1 directly through the structural setting, or be fixed through the combined action of the structure and bonding between the hollow support 3 and the glass kettle body 1.

[0104] In the above embodiment, the handle 4 can be installed at a position corresponding to the hollow support 3. Preferably, the handle 4 covers the hollow support; it can also be installed at other places on the glass kettle body 1. For example, the hollow support 3 is hidden by a housing sleeved on the outer side of the glass kettle body 1, and the connection manner between the handle and the glass kettle body 1 can be through a hooking method or a connection method using an annular tightening member.

[0105] Specifically, the beneficial effects of this embodiment will be explained below in combination with the specific structural form of the hollow support 3:

[0106] In another embodiment, as Figures 14 - 17As shown, the hollowed-out bracket includes two first brackets extending in the height direction, and a limiting rib connecting the first brackets. Among them, the limiting rib is located in the middle of the first brackets. The limiting rib can be one or more. That is, the ends of the two first brackets form openings (in the longitudinal direction, the opening above the hollowed-out bracket is the upper opening, and the opening below the hollowed-out bracket is the lower opening). The limiting rib is located on the side of the PCB detection board 2 facing away from the glass kettle body to limit the radial movement of the PCB detection board 2.

[0107] For example, the limiting rib 39 can be placed at the middle position between the two first brackets 31. At this time, the limiting rib 39 is set to be one. The limiting rib 39 is in contact with the PCB detection board 2. The PCB detection board 2 straddles the limiting rib 39. The two ends of the length of the PCB detection board 2 are adjacent to the two ends of the hollowed-out bracket. At this time, the limiting rib 39 connects the two first brackets.

[0108] In another embodiment, as Figures 14 - 17 shown, the hollowed-out bracket 3 includes two first brackets 31 extending in the height direction. In the width direction of the hollowed-out bracket 3, at least one end of the hollowed-out bracket 3 is open. In this way, at the port of the hollowed-out bracket 3, the first brackets 31 can offset towards the center or the outside of the hollowed-out bracket 3. Thus, when the PCB detection board 2 is inserted into the hollowed-out bracket 3, the two first brackets 31 can be stretched outwards, thereby increasing the distance between the two first brackets 31 at the opening, facilitating the smooth entry of the PCB detection board 2 into the hollowed-out bracket 3; after the PCB detection board 2 enters the hollowed-out bracket 3, then the two first brackets 31 are pressed inwards against the PCB detection board 2, thereby realizing the interference fit of the first brackets 31 to the PCB detection board 2, which can strengthen the fixing strength of the hollowed-out bracket 3 to the PCB detection board 2. It can be understood that the interference fit between the first isolation rib and the PCB detection board 2 can also be a transition fit, or a fit with a small gap.

[0109] In another embodiment, those skilled in the art can think that in addition to the above-mentioned limiting rib 39 being a transverse rib 331 that horizontally connects the first brackets, it can also be as Figure 19 shown, the limiting rib 39 is a suspended transverse rib extending inwards from the side wall of one of the first brackets and not connected to the other first bracket.

[0110] In another embodiment, in this embodiment, in order to enable the hollowed-out bracket 3 to better fix the PCB detection board 2, the hollowed-out bracket 3 includes two first brackets 31 extending in the height direction. The two ends of the first brackets 31 are respectively connected by second brackets 32. The PCB detection board 2 is located between the two first brackets 31.

[0111] By adopting a framework formed by enclosing two first brackets and two second brackets, the PCB detection board is restricted within the framework. In this way, the two first brackets limit the PCB detection board 2 in the circumferential direction (along the circumferential direction of the glass kettle body); the two second brackets limit the PCB detection board 2 in the axial direction (along the height direction of the glass kettle body).

[0112] In another embodiment, those skilled in the art can also think that only a second bracket is provided at one end of the two first brackets, that is, only one second bracket. As Figure 15 and Figure 17 shown, the second bracket 32 can be placed at the lower end (upper end) of the two first brackets 31. The second bracket 32 is provided as one, and the upper end (lower end) of the hollow bracket 3 is set to be an upper opening (lower opening). The length of the PCB detection board 2 is set to be the distance from the second bracket 32 to the upper opening of the hollow bracket 3.

[0113] Alternatively, the movement of the PCB detection board 2 along the axial direction of the glass kettle body 1 is restricted by a stop rib connected to one of the first brackets and suspended.

[0114] In another embodiment, the first isolation ribs 34 are diagonally arranged at the ends of the two first brackets 31 to restrict the movement of the PCB detection board 2.

[0115] In another embodiment, when only two first isolation ribs 34 are diagonally arranged at the ends of the two first brackets 31, the PCB detection board 2 is likely to move in the direction where no first isolation rib 34 is provided at the end under the action of an external force. As a result, in the height direction of the first bracket 31, the width of a part of the first gap 51 near the first isolation rib 34 is larger, and the width of a part of the first gap 51 far from the first isolation rib 34 is smaller, which affects the amount of the fixing glue entering the groove 38 through the first gap 51. Therefore, four first isolation ribs 34 are provided at the ends of the two first brackets 31 to strengthen the limiting effect on the PCB detection board 2.

[0116] In another embodiment, while four first isolation ribs 34 are provided at the ends of the two first brackets 31, two opposite first isolation ribs 34 are provided in the middle part of the PCB detection board 2 to strengthen the limiting effect on the PCB detection board 2.

[0117] In another embodiment, as Figure 9 and Figure 11As shown, as one of the embodiments, the hollowed-out bracket 3 includes two first brackets 31 and two second brackets 32 disposed at both ends of the first brackets 31. The limiting ribs 39 are provided as one vertical rib 332 and three horizontal ribs 331. One of the horizontal ribs 331 forms one side of the anti-overflow frame 37, and one vertical rib 332 passes through two of the horizontal ribs 331 and contacts the anti-overflow frame 37.

[0118] In another embodiment, as Figure 15 shown, the hollowed-out bracket 3 includes two first brackets 31 and one second bracket 32 disposed at the lower ends of the two first brackets 31. The limiting ribs 39 are provided as one vertical rib 332 and three horizontal ribs 331. One of the horizontal ribs 331 forms one side of the anti-overflow frame 37, and one vertical rib 332 passes through two of the horizontal ribs 331 and contacts the anti-overflow frame 37.

[0119] In another embodiment, in other embodiments, the number of longitudinal and transverse limiting ribs 39 is not limited.

[0120] In another embodiment, further, in order to enhance the limitation of the length direction of the PCB detection board 2 by the hollowed-out bracket 3, the limiting ribs 39 extend from the side wall of the second bracket 32 into the hollow area of the hollowed-out bracket 3.

[0121] Specifically, as Figure 18 shown, in order to further enhance the strength of the limitation of the length direction of the PCB detection board 2 by the limiting ribs 39, in the longitudinal direction, the limiting ribs 39 extend and connect the two second brackets 32. In this way, the limiting ribs 39 run through the length direction of the PCB detection board 2, thereby restricting the radial movement of the PCB detection board 2.

[0122] In another embodiment, when the limiting ribs cannot connect the two first brackets, or there is no second bracket for connecting the two first brackets, the hollowed-out bracket may further include connecting ribs connecting the first brackets. Among them, the connecting ribs are located in the middle of the first brackets. The connecting ribs can be one or more, that is, the ends of the two first brackets form openings (in the longitudinal direction, the one above the hollowed-out bracket is the upper opening, and the one below the hollowed-out bracket is the lower opening). The connecting ribs are located on the side of the PCB detection board 2 facing away from the glass kettle body. Specifically, the shape of the connecting ribs can be arched, and the connecting ribs do not contact the PCB detection board 2.

[0123] In another embodiment, when the hollowed-out bracket 3 has two second brackets 32, as Figure 18 shown, the limiting ribs 3 are vertical ribs extending and connecting the two second brackets 32 in the longitudinal direction. Or, as Figure 20As shown, the limiting rib 39 is a suspended vertical rib extending from the side wall of the second bracket 32 into the hollow area of the hollow bracket 3; alternatively, the limiting rib 39 extends obliquely from the side wall of the first bracket 31 to the side wall of the second bracket 32. Of course, those skilled in the art can also understand that in the case of having vertical ribs, there may be no horizontal ribs.

[0124] In another embodiment, as Figure 20 and Figure 22 shown, in the case where the first bracket 31 and the second bracket 32 are provided on the hollow bracket 3, the limiting rib 39 can also be in the form between the side wall of the first bracket 31 and the side wall of the second bracket 32 ( Figure 22 the second bracket 32 shown below). Correspondingly, the first isolation rib 34 provided on the side wall of the first bracket 31 and the second isolation rib 35 of the second bracket 32 can also be provided on both sides of the limiting rib 39. That is, the first isolation rib 34, the second isolation rib 35 and the limiting rib 39 are provided at the corner where the first bracket 31 and the second bracket 32 are connected. Correspondingly, the first isolation rib 34 provided on the side wall of the first bracket 31 and the second isolation rib 35 of the second bracket 32 can also be provided on both sides of the limiting rib 39. The first isolation rib 34, the second isolation rib 35 and the limiting rib 39 cooperate to form a step, and the step cooperates with the corner of the PCB detection board 2 to limit the movement of the PCB detection board 2. In the above embodiment, the formation of the limiting rib and the isolation rib is centralized, and the connection of the two also improves the overall strength.

[0125] In the above embodiments, those skilled in the art can understand that various forms of the limiting rib 39 such as the suspended vertical rib, the vertical rib 332, the horizontal rib 331, and the suspended horizontal rib in this patent can be arbitrarily combined according to requirements.

[0126] In the above embodiments, to prevent consumers from seeing the PCB detection board 2 from the inside of the glass kettle body 1 outward, the glass kettle body 1 usually can also include a silk screen shielding layer (not shown in this embodiment). That is, at the position where the PCB detection board 2 is installed on the outer wall of the glass kettle body 1, a silk screen shielding layer such as ink is also provided. At this time, the silk screen shielding layer can be regarded as a part of the outer wall of the glass kettle body 1. The structure of the glass kettle body 1 in the above embodiment should obviously also be within the scope of protection claimed in this patent.

[0127] In the above embodiments, some slurry substances will rise to a relatively high height, so that the bubbles and foams in the slurry substances will carry some liquid, and the liquid will enter the interior of the handle through the gap between the handle and the glass kettle body. Usually, there are electronic components and other components inside the handle. When the slurry substance comes into contact with the electronic components inside the handle, the detection accuracy of the electronic components will be reduced. In severe cases, the electronic components may even fail, affecting the use experience and service life of the liquid heating container. Or during the cleaning and water filling processes, the liquid will also overflow to the outer surface of the glass kettle body 1, thus posing a risk of contact with the PCB detection board, affecting its service life and stability.

[0128] An electronic component 21 is provided below the PCB detection board 2 opposite to the glass kettle body 1, and the hollow support 3 forms a hollow and closed anti-overflow frame 37, and the anti-overflow frame 37 is arranged around the outer edge of the electronic component 21.

[0129] The electronic component 21 may include a control chip, a wiring port, etc. If the electronic component 21 works in a humid environment for a long time, it will affect the operation speed and service life of the electronic component 21. And if the electronic component 21 is damaged, it is very difficult to replace it with a new electronic component 21. Even if it can be replaced, a relatively cumbersome procedure is required. Especially for the control chip, if the semiconductor and other materials inside are in contact with water vapor for a long time, it will cause damage to it.

[0130] Therefore, an anti-overflow frame 37 is arranged on the hollow support 3 to surround and enclose the electronic component 21, forming a partition from other areas of the PCB detection board 2. In this way, when pouring the fixing glue, it can prevent the fixing glue from overflowing from outside the anti-overflow frame 37 into other areas of the PCB detection board 2, so that the electronic component 21 is covered by the fixing glue, and the control chip can be completely covered by the fixing glue. Thus, it can not only meet the function of quickly pouring and fixing glue in the area of the electronic component 21, but also enable the electronic component 21 to be in a closed environment, preventing the contact between water vapor and the electronic component 21.

[0131] In the above embodiments, since both the shielding layer and the capacitive detection electrode are made of metal materials, when water vapor or liquid enters the interior of the PCB detection board 2, the water vapor or liquid will react with the shielding layer and the capacitive detection electrode made of metal materials. If some or all of the capacitive detection electrodes react with the water vapor, it will cause the height of some liquids to be unable to be detected normally, and in severe cases, the function of detecting the liquid level height will even fail, or the sensitivity of the capacitive detection electrode detection will be reduced. If the water vapor reacts with the shielding layer, it will reduce the interference of the shielding layer to external objects. For example, when the consumer puts a finger close to the capacitive detection electrode, it will affect the judgment of the capacitive detection electrode on the liquid height, resulting in inaccurate detection results.

[0132] For the above reasons, it is necessary to seal the PCB detection board 2 accordingly so that the PCB detection board 2 can work in a dry environment, preventing water vapor or liquid from coming into contact with the PCB detection board 2 and affecting the detection accuracy of the PCB detection board 2.

[0133] When only the first gap 51 and the area near the first gap 51 are filled with the fixing glue, the circumferential direction of the PCB detection board 2 can be sealed and fixed, so that it is difficult for liquid or water vapor to enter the inside of the PCB detection board 2 along the circumferential position of the PCB detection board 2 (the inside refers to the position between the PCB detection board and the glass kettle body).

[0134] Furthermore, when there is a second gap between the hollowed-out bracket and the PCB detection board 2, it cooperates with the first gap to seal and fix the four sides of the PCB detection board, so that it is difficult for liquid or water vapor to enter the inside of the PCB detection board 2 along the longitudinal position of the PCB detection board 2.

[0135] Furthermore, in order to seal the entire PCB detection board, the fixing glue completely covers the side of the PCB detection board facing away from the glass kettle body.

[0136] Because the fixing glue is not filled and fixed in other areas on the side of the PCB detection board 2 facing away from the glass kettle body 1, there is a problem that the side of the PCB detection board 2 facing away from the glass kettle body 1 will be exposed to the water vapor and liquid environment for a long time. Although the detection devices such as the capacitive detection electrodes are arranged on the side of the PCB detection board 2 close to the glass kettle body 1, because the PCB detection board 2 is relatively thin, water vapor may penetrate into the side close to the glass kettle body 1, resulting in poor sealing of the PCB detection board 2 and thus reducing the detection accuracy.

[0137] Specifically, the fixing glue completely covers the PCB detection board 2, and the fixing glue fills each glue filling grid 36 and the anti-overflow frame 37, so that there is no contact between the water vapor and the PCB detection board 2, thereby providing waterproof protection for the PCB detection board 2.

[0138] In the above embodiments, according to the different placement positions of the liquid heating container, the liquid heating container can be divided into two different installation methods:

[0139] For the first installation method, when pouring the fixing glue starting from the uppermost end of the first gap 51, the glass kettle body 1 needs to be placed vertically on the installation table. At this time, when pouring the fixing glue starting from the uppermost end of the first gap 51, the fixing glue will flow along the length direction of the first gap 51 under the action of gravity until the entire first gap 51 is filled.

[0140] The second installation method is to enable the fixing glue to quickly fill the entire first gap 51. The glass kettle body 1 is placed horizontally on the installation table, and the PCB detection board 2 is inserted into the hollow bracket 3 and then attached to the glass kettle body 1. At this time, the installer monitors the installation of the PCB detection board 2 and the hollow bracket 3 in real time from directly above the installation table. Then, the fixing glue is poured around the first gap 51 along the height direction of the hollow bracket 3. At this time, the fixing glue will flow to the first gap 51. At this time, the fixing glue needs to fill the depth of the first gap 51 to fill the first gap 51.

[0141] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0142] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
