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 ensure that the PCB inspection board can always face the glass kettle body, the PCB inspection board is usually placed between the handle and the glass kettle body. For example, in Chinese patent CN106108646A, a PCB inspection board is arranged on the outer wall of the glass kettle body, and the PCB inspection board is fitted on the outer wall of the glass kettle body. The handle is provided with a handle shell, which includes an arc-shaped cavity that matches and encloses the handle and a mounting groove for embedding the PCB inspection board. During the installation process, the prior art fixes the PCB inspection board to the outside of the glass kettle body by applying radial force to the PCB inspection board by the handle. First, during the installation process, the handle is usually set to be opaque. During the process of fixing the PCB inspection board with the handle, the operator cannot monitor the positional relationship between the PCB inspection board and the glass kettle body in real time. As a result, the PCB inspection board will be misaligned with the glass kettle body during the installation process. After the PCB inspection board is installed and fixed, it cannot be fixed along the extension direction of the glass kettle body, and may be tilted or have a gap between it and the glass kettle body. Therefore, in the prior art, the process of installing and fixing the PCB inspection board is relatively complicated, and the positioning of the PCB inspection board is also not accurate enough. In addition, the installation process of fixing the PCB detection board on 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. Utility Model Content

[0006] The present application discloses a liquid heating container, which addresses the technical problem that in the prior art, 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. In particular, when the PCB detection board is fixed to the outer wall of the glass pot body by means of glue, the glue easily overflows from the outer wall of the glass pot body, and the process of installing and fixing the PCB detection board is still relatively complicated.

[0007] The present application relates to a liquid heating container, wherein the outer wall of the glass kettle body is provided with a hollow bracket, the hollow bracket includes a frame arranged on the edge of the hollow bracket, the side of the frame facing the glass kettle body is attached to the outer wall of the glass kettle body, a PCB detection board for air detection is arranged in the frame, and the PCB detection board and the frame are adhered to the outer wall of the glass kettle body by fixing glue in the frame.

[0008] In the present invention, in order to enhance the positioning accuracy of the PCB detection board, a groove is provided on the side of the hollow bracket facing the glass pot body, the groove is located between the frames, the PCB detection board is arranged in the groove, and the fixing glue is arranged in the groove.

[0009] In the present invention, the frame is provided with limiting ribs for limiting the radial movement of the PCB detection board along the glass pot body, so as to set the PCB detection board between the hollow bracket and the outer wall of the glass pot body.

[0010] In the present invention, in order to achieve structural simplification, the hollow bracket includes two first brackets arranged at the edge and extending along the height direction of the glass pot body. The two ends of the two first brackets are respectively connected by two second brackets, and the first bracket and the second bracket are enclosed to form a frame.

[0011] In the present invention, in order to enhance the connection strength between the PCB detection board and the hollow bracket, a first gap is provided between the PCB detection board and the first bracket, which runs radially through the glass pot body. Fixing glue is provided in the first gap to stick and fix the PCB detection board and the first bracket.

[0012] In the present invention, in order to facilitate the formation of the first gap during the installation process, a first isolation rib is extended 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.

[0013] In the present invention, in order to further strengthen the connection strength between the PCB detection board and the glass pot body, the glass pot body includes a curved outer wall, the PCB detection board is installed on the curved outer wall, and 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 arranged in the second gap.

[0014] In the present invention, in order to further strengthen the sealing strength between the hollow bracket and the glass pot body and prevent the fixing glue from overflowing, the part of the hollow bracket facing the glass pot body that is adapted to the curved outer wall is a curved surface.

[0015] In the present invention, in order to further strengthen the sealing strength between the hollow bracket and the glass pot body and prevent the fixing glue from overflowing, the side of the frame facing the glass pot body is adhered with connecting glue to the outer wall of the glass pot body.

[0016] In the present invention, in order to adapt to the split setting mode of the PCB detection board, the PCB detection board includes multiple sub-detection boards that are separately set, and the hollow bracket is provided with multiple frames, and the multiple sub-detection boards are arranged in the frames one by one.

[0017] The utility model provides a liquid heating container, which adopts a hollow bracket and sets an enclosing frame on the edge of the hollow bracket, thereby confining the PCB detection board in the frame of the hollow bracket, and then adding fixing glue in the frame for installation. On the one hand, the PCB detection board and the hollow bracket can be quickly pasted on the outer wall of the glass pot body, thereby realizing an efficient and simple installation method. On the other hand, the frame itself also limits the fixing glue. During the installation of the PCB detection board and after the installation is completed, the fixing glue can be effectively confined in the frame without overflowing, thereby avoiding the subsequent cleaning of the fixing glue, and improving the efficiency of the PCB detection board installation from another level.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] In order to prevent the slurry from rising too high during the cooking process and 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 with the detection area is arranged corresponding to the glass pot body. Therefore, changes in the height of the liquid or the slurry in the glass pot 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. The two can be selected or exist at the same time. When both exist, the anti-overflow detection area is located above the water level detection area.

[0044] For example, the height of the slurry is detected by the PCB detection board. When the height of the slurry is greater than a preset height, the PCB detection board will send a control signal to lower the temperature of the heating tube, thereby causing the height of the slurry to drop to a safe height. During the descent process, the PCB detection board continuously monitors the height of the slurry. When the height of the slurry drops to a safe height, the PCB detection board will send a control signal again to increase the temperature of the heating tube to reheat the food, and the height of the slurry will begin to rise. This process is repeated until cooking is completed.

[0045] The PCB detection board 2 includes a front surface close to the glass kettle body 1 (i.e., the side facing the glass kettle body) and a rear surface opposite the front surface (i.e., the side facing away from the glass kettle body). A metal sheet for signal detection is provided on the front surface, forming a capacitive detection electrode. A control chip and a wiring port are provided on the rear surface of the PCB detection board 2. Data from the capacitive detection electrode is transmitted to the control chip for processing.

[0046] If the slurry substance rises to a high height or the signal detected by the PCB detection board is delayed, the slurry substance is likely to overflow from the through hole above the body of the liquid heating container that is connected to the outside to the outside of the liquid heating container, making it easy for consumers to touch the slurry substance when picking up the liquid heating container, causing burns to consumers or causing the part of the liquid heating container where consumers hold the container to have sticky substances, which will stick to the consumer's hands when the consumer holds the liquid heating container, affecting the consumer's user experience.

[0047] Therefore, if the PCB detection board 2 is not installed properly, causing the PCB detection board 2 to be tilted at an extended height relative to the glass kettle body 1, or is loosely installed, or the positioning height is inaccurate, then the liquid level height of the capacitance value detected on the capacitive detection electrode will be inconsistent with the actual liquid level height that needs 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 the actual required detection height is reached; or it continues to work when the actual required detection height is reached, and even overflows may occur. Therefore, during the installation process, it is necessary to prevent the PCB detection board 2 from being unreliably installed due to uneven force during the installation process or the inability to properly fix the PCB detection board 2.

[0048] During use, food, liquid, etc. may be added to the glass kettle body 1, which increases 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 designed to be hollow, the strength of the handle 4 will be reduced. As a result, when lifting the glass kettle body 1 by the handle 4, the handle 4 may not be strong enough to lift the glass kettle body 1, and in severe cases, the handle 4 may be broken or damaged. Therefore, the handle 4 is generally not designed to be a hollow structure.

[0049] The liquid heating container of the present application may include products such as health pots, electric kettles, soy milk makers and wall breaking machines.

[0050] A liquid heating container of the present application has a hollow bracket provided on the outer wall of a glass kettle body, the hollow bracket includes a frame arranged on the edge of the hollow bracket, the side of the frame facing the glass kettle body is attached to the outer wall of the glass kettle body, a PCB detection board for air detection is provided in the frame, and the PCB detection board and the frame are attached to the outer wall of the glass kettle body by fixing glue in the frame.

[0051] like Figures 1 to 13 In the embodiment shown in Figure 17, the liquid heating container includes a glass kettle body 1 and a handle 4, and the bracket is a hollow bracket 3. The hollow bracket 3 extends along the height direction of the outer wall of the glass kettle body 1. The hollow bracket 3 can be set in a way that the height is greater than the width of the hollow bracket 3.

[0052] In this embodiment, the hollow bracket 3 adopts a closed frame. Specifically, the frame of the hollow bracket 3 in this embodiment includes a first bracket 31 and a second bracket 32. That is, two first brackets 31 extending in the height direction are set at the edge of the hollow bracket 3, and two second brackets 32 set at the edge of the hollow bracket 3 (set along the circumferential direction of the glass pot body 1) are connected at both ends of the first bracket 31, thereby forming an enclosed frame. Here, the formation of an enclosed frame by the hollow bracket 3 can be understood as forming a closed shape in the circumferential direction of the hollow bracket 3 through the frame at the edge. Then, the middle area of the hollow bracket 3 forms a corresponding hollow.

[0053] Through such a structure, a hollow bracket 3 that is adapted to the size of the PCB inspection board 2 is used, and the PCB inspection board 2 is set in the frame of the hollow bracket 3. The frame itself can position the PCB inspection board, which realizes a fast, simple and efficient positioning method for the PCB inspection board 2; and further a gap is set between the PCB inspection board 2 and the frame. The gap can be a gap in the circumference of the PCB inspection board 2, or a gap in some places. In the process of adding fixing glue into the frame, the fixing glue is made to fill the gap between the PCB inspection board 2 and the frame as much as possible and stick to the outer wall of the glass pot body 1, that is, the PCB inspection board 2 and the frame are stuck to the outer wall of the glass pot body 1 together through the fixing glue. This method is very simple. In order to facilitate the fixing glue to fill the gap as much as possible, a silicone material with relatively strong fluidity can be used. The silicone is cured to achieve the PCB inspection board 2 and the frame being stuck to the outer wall of the glass pot body 1 together.

[0054] Of course, those skilled in the art can also imagine that when there is no gap between the PCB detection board 2 and the frame, the frame can also prevent the fixing glue in the frame from overflowing.

[0055] While achieving efficient and easy fixation of the PCB detection board 2, since the side of the frame facing the glass pot body 1 is attached to the outer wall of the glass pot body 1 (direct contact or by pasting with a connection glue similar to 3M), the enclosed frame can also naturally form a restriction on the fixing glue. During the installation process, the fixing glue added to the frame is restricted to prevent the fixing glue from overflowing the frame. After the installation is completed, the fixing glue is also restricted for a long time. In this way, during and after the installation of the PCB detection board 2, the fixing glue will not appear outside the frame, and there will be no situation where the fixing glue overflows on the outer wall of the glass pot body 1. When the fixing glue overflows to the outer wall of the glass pot body 1 outside the frame, the fixing glue itself is a kind of debris that needs to be cleaned. The solution of this patent eliminates the need to clean the fixing glue, which improves the efficiency of the PCB detection board installation from another level.

[0056] It can be understood that because the shape of the hollow bracket is to match the PCB detection board, the hollow bracket of this patent can be set as a trapezoidal enclosing frame structure, a circular enclosing frame structure or a triangular enclosing frame structure based on the PCB detection board 2. The frame structure of the hollow bracket can be connected separately or formed as one piece. Based on the spirit of this patent, the above-mentioned implementation methods should all be within the scope of protection requested by this patent.

[0057] In this embodiment, in order to enhance the positioning accuracy of the PCB detection board 2, a groove 38 is provided on the side of the hollow bracket facing the glass pot body 1. The groove 38 is located between the frames, and the PCB detection board is arranged in the groove. The fixing glue is arranged in the groove. During installation, the PCB detection board 2 is first extended into the groove 38 of the hollow bracket 3, and then one side of the groove 38 in the hollow bracket 3 is placed facing the glass pot body 1. At this time, a receiving 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 a receiving cavity). The PCB detection board 2 is well confined in the receiving 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. The outer edge of the above-mentioned groove can be formed by the first bracket and the second bracket, or it may not be.

[0058] 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.

[0059] In this embodiment, the frame is provided with limiting ribs for limiting the radial movement of the PCB detection board along the glass pot body, so as to set the PCB detection board between the hollow bracket and the outer wall of the glass pot body. It can be understood that the limiting ribs 39 play a role in limiting the detachment of the PCB detection board 2 from the glass pot body 1. In this embodiment, the limiting ribs 39 are provided as one vertical rib 332 and three horizontal ribs 331, wherein the horizontal rib 331 also plays the role of 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. It is also possible to choose to set only the horizontal rib 331 or only the vertical rib 332. This patent specification will be further elaborated later.

[0060] 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 a 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 being separated from the hollow 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 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.

[0061] In this embodiment, in order to enhance the connection strength between the PCB detection board and the hollow bracket, a first gap is provided between the PCB detection board and the first bracket, which runs radially through the glass pot body. Fixing glue is provided in the first gap to stick and fix the PCB detection board and the first bracket.

[0062] It is understandable that, since the first gap 51 is set through, the fixing glue can be directly injected into the first gap 51 from the side of the hollow bracket 3 away from the glass pot body 1, and the fixing glue in the first gap 51 is directly in contact (adhered) with the side of the first bracket 31, the side of the PCB detection board 2 and the outer wall of the glass pot body 1, so as to achieve the purpose of adhering the PCB detection board 2 and the first bracket 31 together on the outer wall of the glass pot body 1. Specifically, when the fixing glue is filled into the first gap 51, the fixing glue connects the PCB detection board 2 and the hollow bracket 3 in the circumferential direction, and the fixing glue is connected to the glass pot body 1 in the radial direction, so as to achieve the purpose of the fixing glue connecting the PCB detection board 2, the hollow bracket 3 and the glass pot body 1 into one, that is, forming a cup body assembly. In the production process of liquid heating containers, forming a cup body assembly in advance is conducive to clear process and accelerated production efficiency. In addition, the fixing glue in the first gap can also play a sealing role.

[0063] On the one hand, the width of the PCB inspection board 2 can be made 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 is a radially penetrating first gap 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 is a first gap 51 on both sides. The first gaps 51 on both sides are glued, so that both 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.

[0064] In this embodiment, to facilitate the formation of the first gap during installation, a first isolation rib extends from the sidewall 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 surfaces of the PCB inspection board from the side surfaces of the first bracket, thereby forming the first gap between the PCB inspection board and the first bracket. Of course, the first gap can be formed between both sides of the PCB inspection board and the first bracket, or only on one side.

[0065] Specifically, a first isolation rib 34 is formed by extending 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 detection board 2 and the side of the first bracket 31, so that a first gap 51 is formed between the PCB detection board 2 and the first bracket 31. By arranging the first isolation rib 34 on the hollow bracket 3, the first isolation rib 34 fits against the side of the PCB detection board 2, directly limiting the movement of the detection board along the circumference of the glass pot body 1, so that 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. Among them, the length of the first isolation rib 34 is generally set to 1-5mm, the thickness is generally set to 1-5mm, and the height is generally set to 1-5mm. In this embodiment, the first isolation rib 34 is arranged on the hollow bracket 3 in an integrated manner, and three first isolation ribs 34 are arranged on each first bracket 31, wherein the middle first isolation rib 34 is arranged on the transverse rib 331. At this time, Figure 13As 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 relatively convenient and fast. Of course, based on the utility model 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.

[0066] 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.

[0067] It is understandable that in this embodiment, 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, which will not be repeated here.

[0068] 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.

[0069] 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.

[0070] In this embodiment, in order to further strengthen the connection strength between the PCB detection board and the glass pot body, the glass pot body includes a curved outer wall, the PCB detection board is installed on the curved outer wall, and 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 can be set in the second gap.

[0071] 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.

[0072] In this embodiment, 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 a 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 adapts 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. When the PCB inspection board 2 is inserted into the hollow bracket 3, 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.

[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 another embodiment, if Figure 14 As shown, the limiting rib 3 is a vertical rib extending in the longitudinal direction to connect the two second brackets 32, or as shown in FIG. Figure 16 As shown, the limiting ribs 39 are suspended vertical ribs extending from the side walls of the second bracket 32 to the hollow area of the hollow bracket 3; of course, those skilled in the art can also understand that when there are vertical ribs, there may be no horizontal ribs.

[0075] In another embodiment, if Figure 15 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.

[0076] In another embodiment, the limiting rib 39 extends 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.

[0077] 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.

[0078] In another embodiment, if Figure 16 、 Figure 18 、 Figure 19 、 Figure 20 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 20 The 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.

[0079] In another embodiment, the frame of the hollow bracket 3 may also be a scheme without the limiting ribs 39, such as Figure 20 shown.

[0080] 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.

[0081] In another embodiment, if Figure 19 As shown, in order to adapt to the split setting mode of the PCB detection board 2, the PCB detection board 2 includes multiple separately set sub-detection boards, and the hollow bracket 3 is provided with multiple frames, and the multiple sub-detection boards are arranged in the frames one by one. Of course, it can be understood by those skilled in the art that the first bracket 31 or the second bracket 32 of the multiple frames can be reused or not ( Figure 19 This is one of the situations where the second bracket is not reused).

[0082] In the above embodiment, the outer wall of the glass pot body 1 can also be provided with a plurality of separately arranged hollow brackets 3.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.
