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 Chinese invention patent CN106108646A, a PCB detection board is provided 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 and wraps the handle, and an installation groove for embedding the PCB detection board. Based on the accuracy and consistency requirements of the PCB detection board detection, it is best that the PCB detection board can be reliably attached to the outer wall of the glass kettle body. However, during the installation process, the above-mentioned prior art fixes the PCB detection board to the outside of the glass kettle body through the radial force of the handle on the PCB detection board. First, during the installation process, the handle is usually set to be opaque. During the process of fixing the PCB detection board with the handle, the operator cannot monitor the positional relationship between the PCB detection board and the glass kettle body in real time. In this way, the PCB detection board will be misaligned with the glass kettle body during the installation process. After the PCB detection board is installed and fixed, it cannot be fixed along the extension direction of the glass kettle body, and problems such as tilted setting or gap between the PCB detection board and the glass kettle body may occur. Therefore, existing technologies have the problem of difficulty in reliably attaching the PCB test board to the outer wall of the glass kettle body, the complexity of the process for fixing the PCB test board, and the inaccurate positioning of the PCB test board. Furthermore, the installation process of fixing the PCB test board to the glass kettle body via the handle is also complicated, affecting installation efficiency.

[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, 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] The present application relates to a liquid heating container, wherein a bracket is provided on the outer wall of the glass kettle body, and a PCB detection board for air detection is provided between the bracket and the outer wall of the glass kettle body. The bracket limits the radial movement of the PCB detection board along the glass kettle body, and the PCB detection board is arranged to protrude from the edge of the bracket and is pressed and held by the bracket to the outer wall of the glass kettle body. The edge of the bracket is fixed to the outer wall of the glass kettle body by fixing glue.

[0008] In the present invention, the bracket is a hollow bracket, including two first brackets arranged at the edge, extending along the height direction of the glass pot body and connected to each other. The PCB detection board is located between the two first brackets and protrudes from the two first brackets. The two first brackets are fixed to the outer wall of the glass pot body by fixing glue.

[0009] In the present utility model, in order to further enhance the positioning accuracy of PCB detection, a groove is provided on the side of the hollow bracket facing the glass pot body, and the groove is located between the two first brackets. The PCB detection board is arranged in the groove, and the thickness of the PCB detection board is greater than the depth of the groove so as to protrude from the two first brackets.

[0010] In the present invention, in order to further enhance the connection strength between the PCB detection board and the first bracket, a radially penetrating first gap is provided between the PCB detection board and the first bracket, and fixing glue is provided in the first gap to stick and fix the PCB detection board and the first bracket.

[0011] In the present invention, in order to further improve the positioning of the PCB detection board by the hollow bracket before installation and better form the first gap, a first isolation rib is formed by extending from the side wall of the first bracket toward the center direction of the hollow bracket. Along the circumference of the glass pot body, the first isolation rib isolates the side surface of the PCB detection board and the side surface of the first bracket, so that the first gap is formed between the PCB detection board and the first bracket.

[0012] In the present invention, in order to further enhance the strength of the hollow bracket itself and its adhesion to the outer wall of the glass pot, the two ends of the two first brackets are respectively connected by a second bracket, the first bracket and the second bracket are enclosed to form a frame, the PCB detection board is confined within the frame, and the second bracket is fixed to the outer wall of the glass pot by fixing glue.

[0013] In the present invention, in order to further improve the adhesive strength of the PCB detection itself, 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. There is a second gap between the two side edges of the plane and the glass pot body, and fixing glue is provided in the second gap.

[0014] In the present invention, the hollow bracket is provided with a limiting rib, and the limiting rib is arranged on the side wall of the first bracket and extends toward the hollow area of the hollow bracket; or, the hollow bracket is provided with a limiting rib, and the limiting rib extends along the transverse direction to connect the two first brackets, so as to limit the radial movement of the PCB detection board along the glass pot body.

[0015] In the present invention, in order to further reduce the difficulty of manufacturing the bracket, the bracket is a plate-shaped bracket, and the PCB detection board is pressed against the outer wall of the glass pot body by the plate-shaped bracket and protrudes from the edge of the bracket. The edge of the plate-shaped bracket is fixed to the outer wall of the glass pot body by fixing glue.

[0016] In the present invention, in order to further improve the positioning of the PCB detection board by the hollow bracket before installation, a groove is provided on the side of the plate-shaped bracket facing the glass pot body, and the PCB detection board is arranged in the groove, and the thickness of the PCB detection board is greater than the depth of the groove.

[0017] The utility model relates to a liquid heating container. A bracket is used to restrict the radial movement of a PCB detection board along a glass container body. The PCB detection board is arranged to protrude from the edge of the bracket, so that the PCB detection board can be reliably attached to the outer wall of the glass container body. This improves the accuracy and consistency of the PCB detection board's detection when the liquid heating container is in operation.

[0018] In addition, the edge of the bracket is fixed to the outer wall of the glass pot body by fixing glue, which greatly simplifies the installation difficulty of the PCB detection board and can also improve the installation accuracy of the PCB detection board;

[0019] In particular, when the PCB inspection board adopts a hollow bracket, the installation of the PCB inspection board is in a completely visible manner. In addition to achieving the adhesion and fixation of the hollow bracket to the outer wall of the glass pot body, the fixing glue can also utilize the gap between the hollow bracket and the PCB inspection board to achieve the adhesion and fixation of the PCB inspection board and the hollow bracket and the outer wall of the glass pot body, which greatly improves the fixing strength of the PCB inspection board.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] The liquid heating container of the present application may include products such as health pots, electric kettles, soy milk makers and wall breaking machines.

[0047] A liquid heating container of the present application is provided with a bracket on the outer wall of a glass kettle body, and a PCB detection board for air detection is provided between the bracket and the outer wall of the glass kettle body. The bracket limits the radial movement of the PCB detection board along the glass kettle body. The PCB detection board is arranged to protrude from the edge of the bracket and is pressed and held by the bracket to the outer wall of the glass kettle body. The edge of the bracket is fixed to the outer wall of the glass kettle body by fixing glue.

[0048] like Figures 1 to 6 In the embodiment shown, the liquid heating container includes a glass kettle body 1 and a handle, and the bracket is a hollow bracket 3. The hollow bracket 3 extends in the height direction on 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.

[0049] The hollow bracket 3 includes two first brackets 31 extending along the height direction at its edge and connected to each other. The PCB detection board 2 for remote detection is located between the two first brackets 31. The hollow bracket 3 is provided with limiting ribs to limit the radial movement of the PCB detection board 2 along the glass pot body 1, that is, to limit the PCB detection board from detaching from the glass pot body 1. In this embodiment, the limiting ribs are provided as one vertical rib 332 and three horizontal ribs 331, wherein the horizontal rib 331 also serves to connect the two first brackets 31. Of course, the number of vertical and horizontal ribs can be selected according to specific needs, or only horizontal ribs can be provided. This patent specification will be further explained later. A groove 38 is provided on the side of the hollow bracket 3 facing the glass pot body 1. The PCB detection board 2 is provided in the groove 38. The thickness of the PCB detection board 2 is greater than the depth of the groove 38, so that the PCB detection board 2 is protruded relative to the two first brackets. The two first brackets 31 are fixed to the outer wall of the glass pot body 1 by fixing glue. To improve the aesthetics, the hollow bracket 3 can be optionally set to be hidden between the handle 4 and the glass pot body 1.

[0050] 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. The stability and accuracy of the signal obtained by the PCB detection board 2 will be greatly improved, and the consistency of signal detection of PCB detection boards of the same batch (used on different machines) is also guaranteed.

[0051] In order to improve the aesthetics of the PCB inspection board 2 after installation and to prevent consumers from seeing the PCB inspection board 2 from the inside of the glass kettle body, the glass kettle body 1 can usually also include a silk screen shielding layer (not shown in this embodiment), that is, the outer wall of the glass kettle body 1 is provided with a silk screen shielding layer at the location where the PCB inspection board 2 is installed. In this case, the silk screen shielding layer can be considered as a part of the outer wall of the glass kettle body 1. The glass kettle body structure of the above embodiment should obviously also be within the scope of protection requested by the claims of this patent.

[0052] It can be understood that in this embodiment, in order to compensate for the height difference between the hollow bracket 3 and the PCB detection board 2, the fixing glue has a certain thickness. For example, silicone and other materials can be selected as the fixing glue. In other subsequent embodiments of this patent, the fixing glue used to fix the edge of the (hollow) bracket to the outer wall of the glass pot body also has a certain thickness.

[0053] 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 2 is generally not very large, in order to ensure the protrusion degree of the PCB detection board 2, the hollow bracket can also be provided with no groove, and two first brackets 31 and a central hollowing method can be used. Based on the inventive intent of this patent, the above embodiment should also be within the scope of protection requested by this patent.

[0054] By adopting the technical solution of setting the groove 38 as described above, during the installation of the PCB inspection board 2, by placing the PCB inspection board 2 into the groove 38 of the hollow bracket 3, the hollow bracket 3 (limiting rib) blocks the PCB inspection board 2 from separating from the hollow bracket 3. During installation, first place the PCB inspection 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 toward the glass pot body 1. It is understandable that the groove 38 is formed by the side of the limiting ribs (the vertical ribs 332 and the horizontal ribs 331 in this embodiment) facing the glass pot body in cooperation with the side faces of the two first brackets 31.

[0055] The depth of the groove 38 may preferably be between 1 and 1.8 mm, and the thickness of the PCB detection board 2 may preferably be between 0.8 and 1.2 mm.

[0056] Of course, in order to strengthen the fixing strength between the PCB detection board 2 and the two first brackets 31, the width of the PCB detection board 2 along the circumferential direction of the glass pot body 1 can be set to be smaller than the width of the hollow bracket 3. In the above-mentioned embodiment of setting the groove 38, the two sides of the PCB detection board 2 respectively have a radially penetrating first gap 51 with the two first brackets 31; a fixing glue is then set in the first gap 51, and the PCB detection board 2 and the hollow bracket 3 are then pasted together by the fixing glue, thereby realizing the strengthened fixation of the PCB detection board 2 and the first bracket 31. It can be understood that since the first gap 51 is set through, the fixing glue in the first gap 51 can then contact (stick) with the outer wall of the glass pot body, thereby realizing that the PCB detection board 2 and the first bracket 31 are pasted together on the outer wall of the glass pot body 1.

[0057] In order to form the first gap 51, a mold can be used to limit the PCB inspection board 2 during the installation process, as long as the width of the PCB inspection board 2 is set to be smaller than the width of the hollow bracket 3. Of course, in order to facilitate the positioning of the PCB inspection board 2 during the installation process, a first isolation rib 34 can also be provided on the first bracket 31. Specifically, the 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 inspection board 2 and 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 fits the side of the PCB inspection board 2, directly preventing the PCB inspection board 2 from moving along the circumference 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, thickness and height of the first isolation rib 34 are generally set to 1-5 mm. In this embodiment, the first isolation rib 34 is provided on the hollow bracket 3 in an integrally formed manner. 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. Alternatively, the first isolation rib 34 can be provided in a suspended state. In this case, Figure 6As 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. (the number of first isolation ribs on the two first brackets may be the same or different, or relatively set, or staggered), 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 invention intention of this patent, the first isolation rib 34 and the first bracket 31 are connected in parts such as adhesion, and the above-mentioned embodiment should also be within the scope of protection requested by this patent.

[0058] By adopting the above-mentioned technical solution of setting the first isolation rib 34, the amount of fixing glue used can also 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 unilaterally.

[0059] In this embodiment, a second bracket 31 is connected to both ends of the first bracket 31, and the second bracket 32 together constitutes the edge of the hollow bracket 3. The second bracket 32 also serves to connect the two first brackets 31. The PCB detection board 2 is also protruding 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.

[0060] By using two first brackets 31 and two second brackets 32 to form a frame structure, the PCB inspection board is confined within the frame, limiting the movement of the PCB inspection board 2 along the height of the glass kettle body 1, which helps improve the efficiency of the PCB inspection board 2 installation process. In other words, the two first brackets limit the position of the PCB inspection board 2 in the circumferential direction (along the circumference of the glass kettle body), and the two second brackets limit the position of the PCB inspection board 2 in the height direction (along the height of the glass kettle body).

[0061] 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 can be set in the third gap 53 for bonding the second bracket 32 and the PCB detection board 2. Accordingly, a second isolation rib 35 can be formed by extending from the side wall of the second bracket 32 toward the center 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, 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.

[0062] 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 9 and Figure 10 As shown), of course, the second bracket may not be provided (as shown Figure 7 and Figure 8 Please select according to actual needs.

[0063] 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 possible to use thinner glass. 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 appearance. 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. Specifically, 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 a fixing glue is set in the second gap 52. When the above solution is adopted, on the one hand, the second gap 52 formed makes the connection between the glass pot body 1 and the PCB detection board 2 more reliable; on the other hand, when the curved outer wall 11 and the hollow bracket 3 clamp the PCB detection board 2, the positioning problem of the PCB detection board 2 is better solved, making the positioning of the PCB detection board 2 more convenient, that is, there is no need to use an external mold to limit the PCB detection board 2.

[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, thereby improving the service life of the PCB detection board 2.

[0065] As previously described, in this embodiment, the limiting ribs 39 are formed by one vertical rib 332 and three horizontal ribs 331, which not only enhances the strength of the hollow bracket 3 but also naturally divides the hollow bracket 3 into a plurality of glue-filled compartments 36 through the crisscrossing arrangement of the limiting ribs 39. The glue-filled compartments 36 are also filled with fixing glue. In this way, the entire periphery of the PCB test board 2 can be sealed with the fixing glue, making it difficult for liquid or water vapor to enter the side of the PCB test board 2 facing the glass pot body 1 along the periphery of the PCB test board 2, thereby improving the protection of the capacitor electrodes on the PCB test board 2.

[0066] Similarly, electronic components 21 are provided below the PCB inspection board 2, facing away from the glass pot body 1. The hollow bracket 3 forms a hollow and closed anti-overflow frame 37, which is arranged around the outer edge of the electronic components 21. The electronic components 21 may include a control chip and a wiring port. If the electronic components 21 operate in a humid environment for a long time, the speed of operation and service life of the electronic components 21 will be affected. If the electronic components 21 are damaged, it is difficult to replace them with new ones. Even if they can be replaced, it requires a relatively cumbersome procedure. In particular, the semiconductor and other materials inside the control chip will be damaged if they come into contact with water vapor for a long time. At this time, the anti-overflow frame 37 is provided on the hollow bracket 3 to surround the electronic components 21 and separate them from other areas of the PCB inspection board 2. In this way, when the fixing glue is poured, the fixing glue can be prevented from overflowing from the anti-overflow frame 37 into other areas of the PCB inspection board 2, so that the electronic components 21 are covered by the fixing glue, and the control chip can be completely covered by the fixing glue. Therefore, the function of quickly injecting the fixing glue into the electronic component 21 area can be satisfied, and the electronic component 21 can be placed in a closed environment to prevent the contact between water vapor and the electronic component 21.

[0067] Below, other embodiments of the hollow bracket of this patent are appropriately described as follows:

[0068] In another embodiment, Figure 7 and Figure 8 As shown, the hollow bracket includes two first brackets 31 extending along the height direction, and a limiting rib 39 connecting the first bracket 31, wherein the limiting rib 39 is located in the middle of the first bracket 31, and the limiting rib 39 can be one or more, that is, the ends of the two first brackets form an opening (in the longitudinal direction, the one located above the hollow bracket is the upper opening, and the one located below the hollow bracket is the lower opening), and the limiting rib 39 is located on the side of the PCB detection board 2 away from the glass pot body 1, so as to limit the radial movement of the PCB detection board 2 in the glass pot body 1.

[0069] In another embodiment, Figure 9 and Figure 10As shown, the second bracket 32 can be placed at the lower end (upper end) of the two first brackets 31, the second bracket 32 is set as one, the upper end (lower end) of the hollow bracket 3 is set as an upper opening (lower opening), and the length of the PCB detection board 2 is set to the distance from the second bracket 32 to the upper opening of the hollow bracket 3.

[0070] exist Figure 9 In the figure, the hollow bracket 3 includes two first brackets 31 and a second bracket 32 arranged at the lower ends of the two first brackets 31. The limiting rib 39 is set as a vertical rib 332 and three horizontal ribs 331, one of which is a horizontal rib 331 forming one side of the anti-overflow frame 37, and a vertical rib 332 passes through two of the horizontal ribs 331 and contacts the anti-overflow frame 37.

[0071] In another embodiment, those skilled in the art may imagine that, in addition to the above-mentioned limiting rib 39 being a horizontal rib connecting the first bracket in a transverse direction, the limiting rib 39 may also be Figure 11 As shown, the limiting rib 39 is a suspended transverse rib extending inward from one of the side walls of the first bracket and not connected to the other first bracket.

[0072] Alternatively, the PCB detection board 2 is restricted from moving in the height direction of the glass pot body 1 by a stop rib connected to one of the first brackets and suspended in the air.

[0073] In another embodiment, Figure 12 As shown, in order to further enhance the strength of the limiting rib 39 in limiting the length direction of the PCB inspection board 2, the limiting rib 39 extends in the longitudinal direction to connect the two second brackets 32. In this way, the limiting rib 39 runs longitudinally along the length of the PCB inspection board 2, thereby limiting the radial movement of the PCB inspection board 2.

[0074] In another embodiment, Figure 13 and Figure 14 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 14 Correspondingly, the first isolation rib 34 provided on the side wall of the first bracket 31 and the second isolation rib 35 of the second bracket 32 can also be provided on both sides of the limiting rib 39. In the above embodiment, the limiting rib and the isolation rib are centralized, and the connection between the two also improves the overall strength.

[0075] In another embodiment, 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 may be arranged to extend 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.

[0076] In another embodiment, in order to further enhance the strength of the limiting rib 39 in limiting the length direction of the PCB detection board 2, the limiting rib 39 can also be provided on the second bracket 32 ( Figure 13 As shown in the second bracket 32 above, the width of the limiting rib 39 can be set to be approximately the same as the length of the second bracket 32, and the limiting rib 39 extends toward the other second bracket 32 (if only one second bracket is set, it extends toward the other section of the hollow bracket). By increasing the width of the limiting rib 39, the strength of the limiting rib 39 in limiting the length direction of the PCB detection board 2 is improved.

[0077] In another embodiment, when the limiting rib cannot connect the two first brackets, or there is no second bracket for connecting the two first brackets, the hollow bracket may also include a connecting rib connecting the first bracket, wherein the connecting rib is located in the middle of the first bracket, and the connecting rib can be one or more, and the connecting rib is located on the side of the PCB detection board 2 away from the glass pot body. Specifically, the shape of the connecting rib can be arched, and the connecting rib has no contact with the PCB detection board 2.

[0078] In another embodiment, the liquid heating container includes a glass kettle body 1 and a handle, and the bracket is a plate-shaped bracket 5. It can be understood that the plate-shaped bracket 5 is a non-hollow bracket, and the plate-shaped bracket 5 can be set in a way that the height of the plate-shaped bracket 5 is greater than the width of the plate-shaped bracket 5.

[0079] In order to facilitate the assembly of the plate-like bracket and the PCB detection board, a groove 38 is provided on the side of the plate-like bracket 5 facing the glass pot body 1, and the PCB detection board 2 is provided in the groove 38. The thickness of the PCB detection board is greater than the depth of the groove. Specifically, the plate-like bracket 5 includes a mounting plate extending along the height direction of the outer wall of the glass pot body 1 and a side plate provided on the circumference of the mounting plate and extending toward the glass pot body. The side plate cooperates with the mounting plate to form the groove 38. At this time, the plate-like bracket 5 is covered on the outside of the PCB detection board 2. It can be understood that the PCB detection board 2 is provided between the mounting plate and the glass pot body 1, the mounting plate completely covers the PCB detection board 2, the side plate is fixed to the outer wall of the glass pot body by fixing glue, and the mounting plate presses the PCB detection board 2 against the outer wall of the glass pot body 1.

[0080] Of course, those skilled in the art will appreciate that the plate-like support 5 can simply be the aforementioned mounting plate, preferably a flat plate, with the PCB detection board 2 pressed against the outer wall of the glass kettle body 1 by the mounting plate and protruding from the edge of the mounting plate, which is fixed to the outer wall of the glass kettle body by adhesive. The mounting plate may be provided with through-holes for accommodating components or wires.

[0081] 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.

[0082] 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.

[0083] 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.
