Description

Technical Field

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

[0002] When cooking or boiling food in a liquid heating container, the food will produce some non-liquid water or other liquid substances during the cooking process. For example, when making soy milk or boiling rice porridge, some soybeans or white rice are first added to the liquid, and the liquid bean mixture or liquid rice mixture is heated using a heating device such as a heating tube in the liquid heating container. During the cooking process, the liquid bean mixture or liquid rice mixture will produce some slurry substances such as bubbles, foam, and pulp.

[0003] In order to prevent the slurry from rising to a high height and overflowing from the liquid heating container, a PCB detection board for remote detection is set on the liquid heating container. The metal sheet on the PCB detection board and the slurry in the liquid heating container form a capacitor. When the slurry in the liquid heating container rises, the capacitance of the capacitor changes, the capacitor charges and discharges, and generates a charge transfer signal on the PCB detection board. The PCB detection board transmits the charge transfer signal to the electronic components, which control the power of the heating tube through the electronic components.

[0004] In the prior art, in order to enable the PCB detection board to always face the glass kettle body, the PCB detection board is usually placed between the handle and the glass kettle body. For example, in patents No. CN106108646A, CN201720159218.0, CN201721038797.X, etc. (more prior art examples are not given here), a PCB detection board is set on the outer wall of the glass kettle body, and the PCB detection board is fitted on the outer wall of the glass kettle body. A handle shell is provided on the handle, and the handle shell includes an arc-shaped cavity that matches the handle and an installation groove for embedding the PCB detection board. During the installation process of the prior art, the PCB detection board is fixed to the outer wall of the glass kettle body by the radial force of the handle on the PCB detection board. First, during the installation process, the handle is usually set to be opaque. When the handle is used to fix the PCB detection board, the operator cannot monitor the positional relationship between the PCB detection board and the glass kettle body in real time. As a result, 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 tilted or there will be a gap between it and the glass kettle body. Therefore, in the prior art, the process of installing and fixing the PCB detection board is relatively complicated, and the positioning of the PCB detection board is not accurate enough. In addition, the installation process of fixing the PCB detection board to the glass kettle body by means of a handle is relatively complicated, which affects the efficiency of the installation.

[0005] There is also patent number CN202222795278.5, which discloses a solution for splitting the handle into a handle frame and a handle body. Even if the handle is split into two parts, the core point is that the handle body presses the handle frame and the temperature measuring element on the outer wall of the kettle body, and the installation is still relatively unstable and complicated. Summary of the Invention

[0006] The present application discloses a liquid heating container, thereby solving the technical problems in the prior art that a PCB detection board is difficult to reliably attach to the outer wall of a glass pot body and the process of installing and fixing the PCB detection board is relatively complicated.

[0007] A liquid heating container of the present application includes a glass kettle body, a hollow bracket and a PCB detection board for air-to-air detection are arranged on the outer wall of the glass kettle body, a groove is arranged on the side of the hollow bracket facing the glass kettle body, and the PCB detection board is placed in the groove; the hollow bracket includes two first brackets extending in the height direction and connected to each other, the PCB detection board is located between the two first brackets, and a limiting rib is arranged on the hollow bracket to limit the radial movement of the PCB detection board along the glass kettle body, and the PCB detection board is located between the hollow bracket and the glass kettle body; along the circumferential direction of the glass kettle body, the width of the PCB detection board is smaller than the width of the hollow bracket, so that the two sides of the PCB detection board have a first gap radially penetrating the glass kettle body with the two first brackets respectively; fixing glue is provided in the first gap, and the PCB detection board and the hollow bracket are adhered to the outer wall of the glass kettle body by the fixing glue.

[0008] Furthermore, the glass pot body includes a curved outer wall, the PCB detection board is installed on the curved outer wall, the side of the PCB detection board facing the curved outer wall is a plane, and there is a second gap between the two side edges of the plane and the glass pot body, so that the fixing glue is set in the second gap.

[0009] Furthermore, the portion of the hollow bracket facing the glass pot body that is adapted to the curved outer wall is a curved surface.

[0010] Furthermore, a connecting glue that matches the curved outer wall is pasted on the side of the hollow bracket facing the glass pot body.

[0011] Furthermore, both ends of the two first brackets are connected by second brackets respectively, and the first brackets and the second brackets are enclosed to form a frame, and the PCB detection board is confined within the frame.

[0012] Furthermore, a second isolation rib is formed extending from the side wall of the second bracket toward the center of the hollow bracket. Along the height direction of the glass pot body, the second isolation rib isolates the end face of the PCB detection board and the side face of the second bracket, so that a third gap is formed between the PCB detection board and the second bracket, and the fixing glue is arranged in the third gap.

[0013] Furthermore, the limiting rib extends from the side wall of the second bracket to the hollow area of ​​the hollow bracket; or, the limiting rib extends along the longitudinal direction to connect the two second brackets; or, the limiting rib extends obliquely from the side wall of the first bracket to the side wall of the second bracket.

[0014] Furthermore, a first isolation rib is formed extending from the side wall of the first bracket toward the center of the hollow bracket. Along the circumference of the glass pot body, the first isolation rib isolates the side of the PCB detection board and the side of the first bracket, so that the first gap is formed between the PCB detection board and the first bracket.

[0015] Furthermore, the limiting rib connects the two first brackets, and the first isolation rib is located on a side of the limiting rib facing the glass pot body and is connected to the limiting rib.

[0016] Furthermore, an electronic component is provided below the PCB detection board away from the glass kettle body, and the hollow bracket forms a hollow and closed anti-overflow frame, which is provided around the outer edge of the electronic component.

[0017] Furthermore, one end of the PCB detection board away from the electronic component passes through the anti-overflow frame and moves toward the top of the hollow bracket, so that the PCB detection board is completely extended into the groove. A wire is provided on the electronic component, and the wire extends out of the anti-overflow frame and extends to the bottom of the glass pot body.

[0018] Furthermore, the fixing glue is filled into the hollow bracket so that the fixing glue completely covers the side of the PCB detection board that is away from the glass pot body.

[0019] Furthermore, the limiting ribs are arranged above the side of the PCB detection board that is away from the glass pot body, and the limiting ribs are crisscrossed to divide the hollow bracket into multiple glue-filled grids; or, the limiting ribs are arranged on the side wall of the first bracket and extend toward the hollow area of ​​the hollow bracket; or, the limiting ribs extend along the horizontal direction to connect two first brackets.

[0020] The liquid heating container of the present application uses a hollow bracket to limit the radial movement of the PCB detection board along the glass kettle body, so that the PCB detection board can be reliably attached to the outer wall of the glass kettle body, thereby improving the accuracy and consistency of the detection of the PCB detection board when the liquid heating container is working. In addition, 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, which greatly simplifies the installation difficulty of the PCB detection board and can also improve the installation accuracy of the PCB detection board; in particular, when the PCB detection board is installed using the hollow bracket, the installation of the PCB detection board is in a completely visible manner. In addition to achieving the adhesive fixation of the hollow bracket and the outer wall of the glass kettle body, the fixing glue can also utilize the gap between the hollow bracket and the PCB detection board to achieve the adhesive fixation of the PCB detection board, the hollow bracket, and the outer wall of the glass kettle body, thereby greatly improving the fixing strength of the PCB detection board.

[0021] The second gap formed makes the connection between the glass pot body and the PCB inspection board more reliable. In particular, when the depth of the groove is greater than the thickness of the PCB inspection board, when the curved outer wall and the hollow bracket clamp the PCB inspection board, the curved outer wall convexes toward the inside of the groove, so that the curved outer wall and the middle part of the PCB inspection board fit better, better solving the limitation problem of the PCB inspection board, that is, there is no need to use an external mold to limit the PCB inspection board, and the detection accuracy of the PCB inspection board is also improved.

[0022] By arranging a first isolation rib on the hollow bracket, the first isolation rib fits against the side of the PCB detection board, directly limiting the circumferential movement of the detection board along the glass pot body. In this way, the width of the first gap can be relatively fixed and will not be changed due to interference from external forces, thereby ensuring the connection strength and strength consistency between the PCB detection board, the hollow bracket, and the glass pot body.

[0023] When the second brackets are connected to both ends of the first bracket, the first and second brackets together form the edges of the hollow bracket. This means that the two first brackets and the two second brackets enclose a frame structure, within which the PCB inspection board is confined. This allows the two first brackets to limit the PCB inspection board's position along the circumference of the glass kettle body, while the two second brackets limit the PCB inspection board's position along the height of the glass kettle body, improving efficiency during the PCB inspection board installation process.

[0046] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0047] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be an intermediate component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be an intermediate component.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0049] In order to prevent the slurry from rising too high during the cooking process and thus overflowing to the outside of the liquid heating container or entering the handle, a PCB detection board capable of remote detection is provided on the liquid heating container. A detection area is provided on one side of the PCB detection board, and the surface provided with the detection area is arranged corresponding to the glass kettle body 1. Thus, changes in the liquid level or the slurry level in the glass kettle body 1 can be monitored by 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 or both can be selected. When both exist, the anti-overflow detection area is generally located above the water level detection area.

[0050] The PCB detection board includes a front surface close to the glass pot body (i.e., the side facing the glass pot body) and a rear surface opposite the front surface (i.e., the side facing away from the glass pot body). A metal sheet for signal detection is provided on the front surface, forming a capacitive detection electrode. A control chip and wiring ports are provided on the rear surface of the PCB detection board. Data from the capacitive detection electrode is transmitted to the control chip for processing.

[0051] If the PCB inspection board is not properly installed, it can affect its inspection accuracy. Specifically, it may stop working before reaching the required inspection height; or continue working even after reaching the required inspection height, even causing overflow. Therefore, during the installation process, it is important to prevent the PCB inspection board from being unreliable due to uneven force or inadequate fixing during installation.

[0052] Furthermore, during use, food, liquid, etc., may be added to the glass kettle, increasing its weight. A handle is used to lift the kettle, and a hollowed-out handle would reduce its strength. Consequently, the handle may become insufficiently strong and unable to lift the kettle, potentially causing cracks and damage. Therefore, handles are generally not hollowed-out. Using a handle to secure the PCB inspection board would also increase installation difficulties.

[0053] The liquid heating container of the present application may include products such as health pots, electric kettles, soy milk makers and wall breaking machines.

[0054] A liquid heating container of the present application includes a glass kettle body 1, and a hollow bracket 3 extending in the height direction is provided on the outer side of the glass kettle body 1, and a PCB detection board 2 for air detection is provided between the hollow bracket 3 and the glass kettle body 1. A groove 38 is provided on the side of the hollow bracket 3 facing the glass kettle body 1, and the PCB detection board is placed in the groove 38. The hollow bracket 3 limits the radial movement of the PCB detection board 2 along the glass kettle body 1. In the circumferential direction, the width of the PCB detection board 2 is smaller than the width of the hollow bracket 3, so that there are two radially penetrating first gaps 51 between the two sides of the PCB detection board 2 and the hollow bracket 3; fixing glue is provided in the first gap 51, and the PCB detection board 2 and the hollow bracket 3 are adhered to the outer side of the glass kettle body 1 by the fixing glue.

[0055] In order to be able to hold more liquid, the glass kettle body 1 is usually a long cylindrical shape, and in order to improve the accuracy of overflow detection and / or water level detection, the PCB detection board 2 is usually set to a long strip with a suitable width. At this time, the long strip PCB detection board 2 can not only well cover the height of the liquid in the glass kettle body 1, but also enable the PCB detection board 2 to monitor the liquid level height in real time; and because the PCB detection board 2 has an appropriate width, it can simultaneously meet the accuracy requirements of overflow detection and / or water level detection. In order to be able to adapt to the general form of the above-mentioned PCB detection board 2, the hollow bracket 3 extends in the height direction on the outer wall of the glass kettle body 1, and the hollow bracket 3 can be set in a manner that the height is greater than the width of the hollow bracket 3. Of course, those skilled in the art can imagine that the size of the detection board can be changed according to specific detection requirements, and the size of the hollow bracket can also be changed. For example, the hollow bracket 3 can be set in a manner that the height is equal to the width of the hollow bracket 3.

[0056] like Figures 1 to 13 and Figure 21 In the embodiment shown, the hollow bracket 3 includes two first brackets 31 arranged at its edge, extending in the height direction and connected to each other, and the PCB detection board 2 is located between the two first brackets 31. A limiting rib 39 is provided on the hollow bracket 3 to limit the radial movement of the PCB detection board 2 along the glass pot body 1. It can be understood that the limiting rib 39 plays a role in limiting the PCB detection board 2 from detaching from the glass pot body 1. In this embodiment, the limiting rib 39 is set to a vertical rib 332 and three horizontal ribs 331, wherein the horizontal rib 331 also plays a role in connecting the two first brackets 31. Of course, the number of vertical ribs 332 and horizontal ribs 331 can be selected according to specific needs, or it can be selected to set only the horizontal rib 331 or only the vertical rib 332. This patent specification will be further elaborated later.

[0057] In this embodiment, to secure the PCB inspection board 2 and the two first brackets 31 to the glass kettle body, the width of the PCB inspection board 2 along the circumference of the glass kettle body 1 can be set to be smaller than the width of the hollow brackets 3, so that a first gap 51 radially extending between the two first brackets 31 and each side of the PCB inspection board 2 is formed. That is, the width of the PCB inspection board 2 is set to be smaller than the distance between the two first brackets 31. Fixing glue is then provided within the first gaps 51, and the PCB inspection board 2 and the hollow brackets 3 are then adhered together by the fixing glue, thereby achieving a strong fixation between the PCB inspection board 2 and the first brackets 31. It will be appreciated that because the first gaps 51 are provided through the glass kettle body, fixing glue can be directly injected into the first gaps 51 from the side of the hollow brackets 3 facing away from the glass kettle body 1. The fixing glue within the first gaps 51 directly contacts (adheres to) the side surfaces of the first brackets 31, the side surfaces of the PCB inspection board 2, and the outer wall of the glass kettle body 1, thereby achieving the purpose of affixing the PCB inspection board 2 and the first brackets 31 to the outer wall of the glass kettle body 1. Specifically, when the fixing glue is filled into the first gap 51, the fixing glue connects the PCB inspection board 2 and the hollow bracket 3 in the circumferential direction, and connects to the glass kettle body 1 in the radial direction, thereby achieving the purpose of the fixing glue connecting the PCB inspection board 2, the hollow bracket 3, and the glass kettle body 1 into one body, that is, forming a cup body assembly. During the production process of liquid heating containers, forming the cup body assembly in advance helps to clarify the process and speed up production efficiency. In addition, the fixing glue in the first gap can also serve as a seal.

[0058] On the one hand, the width of the PCB inspection board 2 is smaller than the width of the hollow bracket 3, so that there can be a gap between the PCB inspection board 2 and the hollow bracket 3; on the other hand, the PCB inspection board 2 can be limited by the mold in the process or by the hollow bracket 3, so that there are radially penetrating first gaps 51 between the two sides of the PCB inspection board 2 and the hollow bracket 3 and the two first brackets 31, that is, there are first gaps 51 on both sides. The first gaps 51 on both sides are glued, so that the two sides of the long hollow bracket 3 and the long PCB inspection board 2 can be fixed to the glass pot body 1 by fixing glue, and the first gap 51 is located in the longitudinal direction of the hollow bracket 3, which is more conducive to extending the length of the first gap 51 and improving the reliability of the connection.

[0059] In order to form a stable first gap 51, the width of the PCB inspection board 2 is set to be smaller than the width of the hollow bracket 3 along the circumferential direction of the pot body, 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 toward the center of the hollow bracket 3. Along the circumference of the glass pot body 1, the first isolation rib 34 isolates the side of the PCB inspection board 2 from the side of the first bracket 31, so that a first gap 51 is formed between the PCB inspection board 2 and the first bracket 31. By providing the first isolation rib 34 on the hollow bracket 3, the first isolation rib 34 is in contact with the side of the PCB inspection board 2, directly limiting the movement of the inspection board along the circumferential direction of the glass pot body 1. In this way, the width of the first gap 51 can be relatively fixed, and the width of the first gap 51 will not be changed due to interference from external forces. 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 ribs 34 are provided on the hollow bracket 3 by an integral molding method. Three first isolation ribs 34 are provided on each first bracket 31, wherein the middle first isolation rib 34 is provided on the transverse rib 331. Figure 13 As shown, the first isolation rib 34 divides the first gap 51 into multiple sections. Of course, those skilled in the art will understand that there may or may not be a gap between the first isolation rib 34 and the glass pot body 1; the number of first isolation ribs 34 on the first bracket 31, whether they are set on the transverse rib 331, whether they are symmetrical, etc., can also be selected according to specific needs, and this patent specification will be further elaborated later. In addition, the way the first isolation rib 34 and the first bracket 31 are integrally formed is also more convenient and quick. Of course, based on the invention intention of this patent, the above-mentioned embodiment should also be within the scope of protection requested by this patent in the way that the first isolation rib 34 and the first bracket 31 are connected in parts such as adhesion.

[0060] By adopting the above-mentioned technical solution of setting the first isolation rib 34, the amount of the fixing glue can be accurately determined when setting the fixing glue in the first gap 51, thereby improving the connection strength between the PCB detection board 2 and the first bracket 31 on the glass pot body 1. 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 setting the first isolation rib 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 as needed. Of course, those skilled in the art can also conceive that the first gap 51 in this embodiment can also be set on one side, and the other side can be sealed by other means. Among them, those skilled in the art can conceive that the first isolation rib 34 and the PCB detection board 2 can be a transition fit, an interference fit, or a small gap fit, all of which are within the scope of this embodiment.

[0061] In this embodiment, second brackets 32 are connected to both ends of the first bracket 31. Together, the first and second brackets 31, 32 form the edges of the hollow bracket 3. Specifically, two first brackets 31 and two second brackets 32 enclose a frame structure, within which the PCB inspection board 2 is confined. The two first brackets 31 limit the PCB inspection board 2 circumferentially (along the circumference of the glass kettle body 1), while the two second brackets 32 limit the PCB inspection board 2 axially (along the height of the glass kettle body 1), which helps improve the efficiency of the PCB inspection board 2 installation process.

[0062] It is understandable that a third gap 53 can also be set between the second bracket 32 ​​and the PCB detection board 2, and a fixing glue is set in the third gap 53 for bonding the second bracket 32 ​​and the PCB detection board 2. Accordingly, a second isolation rib 35 is formed by extending from the side wall of the second bracket 32 ​​toward the center direction of the hollow bracket 3. Along the height direction of the glass pot 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 that a third gap 53 is formed 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 is directly in contact (adhered) with the side face of the second bracket 32, the side face of the detection board, and the outer wall of the glass pot 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. They will not be repeated here.

[0063] Those skilled in the art may also think that the second bracket 32 ​​may be provided at only one end of the two first brackets 31 (eg Figure 15 and Figure 17 As shown), of course, the second bracket 32 ​​may not be provided (as shown Figure 14 and Figure 16 As shown), the specific selection is based on actual needs, and this patent specification will be further elaborated later.

[0064] In this embodiment, the fixing glue can also be filled into the hollow bracket 3, so that the fixing glue completely covers the side of the PCB detection board 2 opposite to the glass pot body 1, and the PCB detection board 2 in this embodiment is also connected to the limiting rib 39 through the fixing glue.

[0065] Specifically, a vertical rib 332 and three horizontal ribs 331 are arranged in a crisscross pattern to divide the hollow support 3 into a plurality of glue-filled compartments 36. The compartments are then filled with adhesive, and the PCB inspection board 2 is also connected to the vertical rib 332 and three horizontal ribs 331 via adhesive. This allows the entire perimeter of the PCB inspection board 2 to be sealed with adhesive, making it difficult for liquid or water vapor to enter the side of the PCB inspection board 2 facing the glass pot body 1 along the perimeter of the PCB inspection board 2.

[0066] A groove 38 is provided on the side of the hollow bracket 3 facing the glass pot body 1. Specifically, it can be understood that in this embodiment, the side of the horizontal rib 331 and the vertical rib 332 facing the glass pot body 1 cooperates with the side surfaces 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, by placing the PCB detection board 2 into the groove 38 of the hollow bracket 3, the PCB detection board 2 can be embedded in the groove 38. At the same time, due to the blocking effect of the hollow bracket 3, that is, the blocking effect of the limiting rib 39, the PCB detection board 2 is prevented from escaping from the hollow bracket 3. Based on the inventive intent of this patent, the formation of the groove 38 can be selected according to the specific structure of the hollow bracket 3. For example, the side surfaces 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. This patent specification will be further elaborated later.

[0067] During installation, first extend the PCB detection board 2 into the groove 38 of the hollow bracket 3, and then place one side of the groove 38 in the hollow bracket 3 facing the glass pot body 1. At this time, a accommodating cavity is formed between the hollow bracket 3 and the outer wall of the glass pot body 1 (it can also be understood that the groove 38 and the outer wall of the glass pot body 1 form an accommodating cavity), and the PCB detection board 2 is well confined in the accommodating cavity, that is, the limiting rib 39 limits the radial movement of the PCB detection board 2 along the glass pot body 1, the first bracket 31 limits the circumferential movement of the PCB detection board 2 along the glass pot body 1, and the second bracket 32 ​​limits the movement of the PCB detection board 2 along the height direction of the glass pot body 1.

[0068] The applicant has discovered that if too much adhesive is poured, it can easily overflow from the area where the two components meet, onto the outside of the hollow bracket 3, and into the glass kettle body 1. Since the overflowing adhesive has not completely dried, other components may come into contact with it during installation, potentially adhering to the glass kettle body 1. Furthermore, the adhesive that has overflowed onto the glass kettle body 1 is difficult to clean, affecting the overall appearance of the liquid heating container. When the thickness of the PCB inspection board 2 is no greater than the depth of the groove 38, the groove 38 not only improves assembly convenience before placement, i.e., the PCB inspection board 2 can be fully embedded in the groove 38. This prevents the PCB inspection board 2 from easily falling out of the hollow bracket 3, but also allows the sides of the first bracket 31 and the second bracket 32 ​​facing the glass kettle body 1 to be closer to the outer wall of the glass kettle body 1. This effectively prevents the adhesive in the first gap 51 from overflowing from the areas between the first bracket 31 and the glass kettle body 1, and between the second bracket 32 ​​and the glass kettle body 1.

[0069] In order to reduce the overflow of the poured fixing glue, when the outer wall of the glass pot body 1 is set to be the curved outer wall 11, in order to make the fit between the hollow bracket 3 and the curved outer wall 11 tighter and reduce the possibility of the fixing glue overflowing from the position between the edge of the hollow bracket 3 and the glass pot body 1, the part of the hollow bracket 3 facing the glass pot body 1 that is adapted to the curved outer wall 11 is a curved surface 311. At this time, when the hollow bracket 3 is pressed against the glass pot body 1, the curved surface 311 and the curved outer wall 11 fit more tightly, achieving the purpose of no gap or insufficient gap to prevent glue from overflowing to the outside of the hollow bracket 3. That is, the thickness of the PCB inspection board 2 is not greater than the depth of the groove 38, and the PCB inspection board 2 is inserted into the hollow bracket 3, and the side of the PCB inspection board 2 facing the glass pot body 1 does not protrude from the curved surface 311 of the hollow bracket 3.

[0070] Of course, those skilled in the art can imagine that when the thickness of the PCB detection board 2 is greater than the depth of the groove 38, the PCB detection board 2 is protruded relative to the two first brackets 31, and the two first brackets 31 are fixed to the outer wall of the glass pot body 1 by fixing glue. In this way, there is a height difference between the PCB detection board 2 and the two first brackets 31, that is, the PCB detection board 2 is closer to the outer wall of the glass pot body 1 relative to the two first brackets 31 (that is, the edges of the hollow brackets 3). After the two first brackets 31 are fixed to the outer wall of the glass pot body 1 by fixing glue, the PCB detection board 2 can be reliably attached to the outer wall of the glass pot body 1 under the restriction and pressure of the limiting ribs 39. The stability and accuracy of the signal obtained by the PCB detection board 2 will be greatly improved, and the consistency of the signal detection of the PCB detection boards 2 of the same batch (used on different machines) is also guaranteed. Similarly, when there is a second bracket 32, the PCB detection board 2 can also be set to protrude from the second bracket 32. The second bracket 32 ​​is also fixed to the outer wall of the glass pot body 1 by fixing glue. As mentioned above, the fixing glue used to fix the second bracket 32 ​​also has a certain thickness. The way the second bracket 32 ​​is pasted to the outer wall of the glass pot body 1 is similar to that of the first bracket 31, and will not be repeated here.

[0071] In the above embodiment, the purpose of setting the groove 38 is to limit the circumferential direction of the PCB detection board 2 on the outer wall of the glass pot body 1, which can improve the efficiency of installing the PCB detection board 2 to a certain extent. Of course, since the thickness of the PCB detection is generally not very large, the depth of the groove 38 can generally be between 1 and 1.8 mm, and the thickness of the PCB detection board 2 can generally be between 0.8 and 1.2 mm.

[0072] It is understandable that in order to make the contact area between the PCB detection board 2 and the outer wall of the glass pot body 1 larger, it is generally conceivable to make the mating surfaces of the glass pot body 1 and the PCB detection board 2 the same shape, such as a flat surface with a flat surface, and a curved surface with a curved surface. In products, especially the glass pot body 1 of the health pot type, it is preferably made of thinner glass. At this time, it is difficult to achieve a flat surface by cutting it thin (easy to break). Even if it can be achieved by a concave method, it will affect the beauty of the pot body. The applicant found that when the solution of this patent is adopted, even if the mating surfaces of the glass pot body 1 and the PCB detection board 2 are not the same shape, there is a better effect. In this embodiment, the glass pot body 1 includes a curved outer wall 11, and the PCB detection board 2 is installed on the curved outer wall 11. The side of the PCB detection board 2 facing the curved outer wall 11 is a plane. There is a second gap 52 between the two side edges of the plane and the glass pot body 1, so that the fixing glue is set in the second gap 52. When adopting the above scheme, on the one hand, the second gap 52 formed makes the connection between the glass pot body 1 and the PCB detection board 2 more reliable. On the other hand, when the depth of the groove 38 is greater than the thickness of the PCB detection board 2, the curved outer wall 11 and the hollow bracket 3 clamp the PCB detection board 2, the curved outer wall 11 convexes toward the groove 38 so that the curved outer wall and the middle part of the PCB detection board 2 fit better, better solving the limiting problem of the PCB detection board 2, that is, there is no need to use an external mold to limit the PCB detection board 2, and the detection accuracy of the PCB detection board 2 is also improved.

[0073] In this embodiment, to more conveniently position the hollow bracket 3 on the outer wall of the glass kettle body 1, a pre-attached adhesive, such as 3M adhesive or double-sided tape, can be applied to the curved surface 311. This adhesive can then be used to directly adhere the hollow bracket 3 to the glass kettle body 1, effectively positioning the hollow bracket 3. Furthermore, this adhesive will not flow freely, thereby affecting the aesthetics. After the PCB inspection board 2 is inserted into the hollow bracket 3, the hollow bracket 3 is first secured to the glass kettle body 1 using the adhesive. Once the hollow bracket 3 is securely fixed, the adhesive is then poured into the hollow bracket 3.

[0074] In this embodiment, the electronic component 21 is disposed below the PCB inspection board 2, away from the glass kettle body 1. The hollow bracket 3 forms a hollow and closed anti-overflow frame 37, which is disposed around the outer edge of the electronic component 21. The end of the PCB inspection board 2, away from the electronic component 21, passes through the anti-overflow frame 37 and moves upward from the hollow bracket 3, so that the PCB inspection board 2 is fully inserted into the groove 38. Wires are disposed on the electronic component 21, extending from the anti-overflow frame 37 and toward the bottom of the glass kettle body 1.

[0075] The electronic component 21 may include a control chip and a wiring port. If the electronic component 21 operates in a humid environment for a long time, it will affect the speed of the electronic component 21 operation and the service life. If the electronic component 21 is damaged, it is difficult to replace it with a new electronic component 21. Even if it can be replaced, it requires a relatively cumbersome procedure. In particular, the control chip, the semiconductor and other materials inside it will be damaged if they come into contact with water vapor for a long time. Therefore, an anti-overflow frame 37 is set on the hollow bracket 3 to surround the electronic component 21 and form a partition with other areas of the PCB detection board 2. In this way, when pouring the fixing glue, the fixing glue can be prevented from overflowing from 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. This can not only meet the function of quickly pouring the fixing glue into the electronic component 21 area, but also enable the electronic component 21 to be in a closed environment to prevent contact between water vapor and the electronic component 21.

[0076] In another embodiment, Figure 14 、 Figure 16 As shown, the hollow bracket 3 lacks the second bracket 32, and the limiting rib 39 can be one or more transverse ribs 331 that transversely connect the two first brackets 31. In this case, the limiting rib 39 not only connects the two first brackets 31 but also limits the movement of the PCB detection board 2. In this embodiment, the transverse rib 331 cooperates with the side walls of the two first brackets 31 to form a groove 38.

[0077] In another embodiment, Figure 15 and Figure 17 As shown, the second bracket 32 ​​can be placed at the lower end or upper end of the two first brackets 31, that is, the second bracket 32 ​​is set as one, and the upper end or lower end of the hollow bracket 3 is set to form an opening. It can be understood that the vertical rib 332 can be set in the form of the vertical rib 332 in this embodiment, in addition to the vertical rib 332 extending in the longitudinal direction to connect the transverse rib 331 and the second bracket 32, as shown in FIG. Figure 15 As shown, vertical ribs 332 are connected to the horizontal ribs 331 along the longitudinal direction, wherein one end of the vertical rib 332 can be suspended. Of course, those skilled in the art will also understand that vertical ribs 332 may be absent when horizontal ribs are present.

[0078] In another embodiment, Figure 19 As shown, when the first brackets 31 do not need to be connected by the transverse rib 331, the limiting rib 39 is a suspended transverse rib extending inward from the side wall of one of the first brackets 31 and not connected to the other first bracket 31. In this embodiment, the two first brackets 31 are connected by the second bracket 32.

[0079] In another embodiment, when the hollow bracket 3 has two second brackets 32, as shown in FIG. Figure 18 As shown, the limiting rib 3 is a vertical rib extending in the longitudinal direction to connect the two second brackets 32. Alternatively, as Figure 20 As shown, the limiting ribs 39 are suspended vertical ribs extending from the side walls of the second bracket 32 ​​toward the hollow area of ​​the hollow bracket 3; alternatively, the limiting ribs 39 extend obliquely from the side walls of the first bracket 31 to the side walls of the second bracket 32. Of course, those skilled in the art will also understand that in the case of vertical ribs, there may be no horizontal ribs.

[0080] It is understood that in order to further enhance the connection strength between the first bracket 31 and the second bracket 32, the limiting rib 39 can be extended obliquely from the side wall of the first bracket 31 to the side wall of the second bracket 32 ​​(not shown). When the limiting rib 39 obliquely connects the first bracket 31 and the second bracket 32, when an external force is applied to the first bracket 31, the limiting rib 39 connected to the first bracket 31 can offset the effect of the external force on the first bracket 31; when an external force is applied to the second bracket 32, the limiting rib 39 connected to the second bracket 32 ​​can offset the effect of the external force on the second bracket 32.

[0081] When the limiting rib 39 is connected obliquely to the first bracket 31 and the second bracket 32, when an external force is applied to the first bracket 31, the limiting rib 39 connected to the first bracket 31 can offset the effect of the external force on the first bracket 31; when an external force is applied to the second bracket 32, the limiting rib 39 connected to the second bracket 32 ​​can offset the effect of the external force on the second bracket 32. Figure 20 As shown, in order to further improve the strength of the limiting rib 39 in the length direction of the PCB detection board 2, the limiting rib 39 is set on the second bracket 32, the width of the limiting rib 39 is roughly the same as the length of the second bracket 32, and the limiting rib 39 extends in the direction of the other second bracket 32. By increasing the width of the limiting rib 39, the strength of the limiting rib 39 in the length direction of the PCB detection board 2 is improved.

[0082] In another embodiment, Figure 20 and Figure 22 As shown, in the case where the hollow bracket 3 is provided with the first bracket 31 and the second bracket 32, the limiting rib 39 can also be formed by extending from the side wall of the first bracket 31 to the side wall of the second bracket 32 ​​( Figure 22The first isolation rib 34 and the second isolation rib 35 of the second bracket 32 ​​are 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, and the first isolation rib 34 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 together also improves the overall strength.

[0083] In the above embodiments, those skilled in the art will appreciate that various forms of limiting ribs 39 such as suspended vertical ribs, vertical ribs 332, horizontal ribs 331, and suspended horizontal ribs in this patent can be arbitrarily combined as needed.

[0084] In the above embodiments, those skilled in the art will appreciate that when the limiting rib 39 cannot connect the two first brackets 31, or there is no second bracket 32 ​​for connecting the two first brackets 31, the hollow bracket 3 may further include a connecting rib (not shown) connecting the first brackets 31, wherein the connecting rib may be located in the middle of the first bracket 31, and the number of the connecting rib may be one or more. Specifically, the connecting rib is located on the side of the PCB detection board 2 facing away from the glass pot body 1, and the shape of the connecting rib may be arched, and the connecting rib has no contact with the PCB detection board 2.

[0085] In the above embodiment, the liquid heating container further includes a handle 4, and the handle 4 can be connected to the glass kettle body 1 by hooking or by an annular fastening member. The handle 4 can be added to the place corresponding to the hollow bracket 3, or it can be added to other places of the glass kettle body 1. For example, in order to improve the aesthetics, the handle 4 covers the hollow bracket 3. Preferably, the hollow bracket 3 can be selected to be hidden between the handle 4 and the glass kettle body 1. Of course, those skilled in the art can also imagine that the kettle body can also have no handle, or the handle is in an arched shape, and the hollow bracket 3 can also be hidden by a shell that is sleeved on the outside of the glass kettle body 1.

[0086] In the above embodiment, to prevent consumers from seeing the PCB inspection board 2 from the inside of the glass kettle body 1, the glass kettle body 1 can also generally include a silk-screened shielding layer (not shown in this embodiment). That is, a silk-screened shielding layer, such as ink, is also provided on the outer wall of the glass kettle body 1 at the location where the PCB inspection board 2 is installed. In this case, the silk-screened shielding layer can be considered 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 requested by the claims of this patent.

[0087] The technical features of the above-described embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as no contradiction exists between these combinations of technical features, they should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be deemed that the drawing also discloses examples of combinations of the various embodiments involved.

[0088] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the spirit of the present application, and such modifications and improvements are all within the scope of protection of the present application.
