Abstract
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] In the process of 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, in the process of making soy milk or boiling rice porridge, some soybeans or white rice are first added to the liquid, and the liquid bean mixture or the liquid rice mixture is heated by a heating device such as a heating tube in the liquid heating container. During the cooking process, the liquid bean mixture or the liquid rice mixture will produce some bubbles, foam, pulp and other pulp substances.
[0003] In order to prevent the slurry material 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 material in the liquid heating container form a capacitor. When the height of the slurry material 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, and the power of the heating tube is controlled by 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 arranged 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 arranged 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. In the prior art, during the installation process, 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 the PCB detection board 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] In addition, patent number CN202222795278.5 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 against 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] 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 limiting ribs are 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 that penetrates radially along the glass kettle body with the two first brackets respectively; fixing glue is arranged 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 an arc-shaped outer wall, the PCB detection board is installed on the arc-shaped outer wall, the side of the PCB detection board facing the arc-shaped 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.
[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 matching with the arc-shaped 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, 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 direction of the hollow bracket, and 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] Further, 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 direction of the hollow bracket, and 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 to form the first gap 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 arranged below the PCB detection board and away from the glass kettle body, and the hollow bracket forms a hollow and closed anti-overflow frame, and the anti-overflow frame is arranged 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, and 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 opposite to the glass pot body.
[0019] Further, the limiting ribs are arranged above the side of the PCB detection board that is opposite to the glass pot body, and the limiting ribs crisscross to divide the hollow bracket into a plurality of glue-filled grids; or, the limiting ribs are arranged on the side walls of the first bracket and extend toward the hollow area of the hollow bracket; or, the limiting ribs extend in the lateral direction to connect the two first brackets.
[0020] A 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 a hollow bracket, the installation of the PCB detection board is in a completely visible manner. In addition to realizing the adhesive fixation of the hollow bracket and the outer wall of the glass kettle body, the fixing glue can also use the gap between the hollow bracket and the PCB detection board to realize the adhesive fixation of the PCB detection board and 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, especially 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, thereby 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 the first isolation rib on the hollow bracket, the first isolation rib is in contact with the side of the PCB detection board, directly limiting the circumferential movement of the detection board along the glass pot body, so that the width of the first gap can be relatively fixed, and the width of the first gap 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 bracket and the second bracket together form the edge of the hollow bracket, that is, the two first brackets and the two second brackets are used to enclose a frame structure, and the PCB detection board is confined within the frame. The two first brackets limit the PCB detection board along the circumference of the glass pot body, and the two second brackets limit the PCB detection board along the height direction of the glass pot body, which is conducive to improving the efficiency of the PCB detection board during the installation process.

[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work 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 a central 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 a central component at the same time.
[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0049] In order to prevent the height of the slurry from rising too high during the cooking process and thus overflowing to the outside of the liquid heating container or entering the inside of the handle, a PCB detection board that can be detected remotely is provided on the liquid heating container, and a detection area is provided on one side of the PCB detection board, and the surface provided with the detection area is provided corresponding to the glass kettle body 1, so that the change of the liquid height or the change of the slurry height 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 according to the monitored height. The detection area can be divided into a water level detection area or an anti-overflow detection area, and the two can be selected or exist at the same time. 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 kettle body (i.e., the side facing the glass kettle body), and a rear surface arranged opposite to the front surface (i.e., the side away from the glass kettle body). A metal sheet for signal detection is arranged on the front surface to form a capacitive detection electrode. A control chip and a wiring port are arranged on the rear surface of the PCB detection board, and the data of the capacitive detection electrode is transmitted to the control chip and processed by the control chip.
[0051] If the PCB inspection board is not installed properly, it will affect the inspection accuracy of the PCB inspection board. Specifically, it stops working before reaching the actual required inspection height; or it continues to work at the actual required inspection height, and even causes overflow. Therefore, during the installation process, it is necessary to prevent the PCB inspection board from being unreliably installed due to uneven force during the installation process or failure to properly fix the PCB inspection board.
[0052] In addition, during use, food and liquid will be added to the inside of the glass kettle, which will increase the weight of the glass kettle. The handle is used to lift the glass kettle. If the handle is set to a hollow shape, the strength of the handle will be reduced. In the process of lifting the glass kettle by the handle, the handle will not be able to lift the glass kettle due to insufficient strength, and the handle may be broken or damaged in serious cases. Therefore, the handle is generally not made into a hollow structure. If the handle is used to fix the PCB detection board, it will also increase the difficulty of installation.
[0053] The liquid heating container of the present application may include products such as a health pot, an electric kettle, a soymilk maker, and a wall breaking machine.
[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 arranged on the outer side of the glass kettle body 1, a PCB detection board 2 for air detection is arranged between the hollow bracket 3 and the glass kettle body 1, and a groove 38 is arranged 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, and 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; a fixing glue is arranged 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 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 cover the height of the liquid in the glass kettle body 1 well, but also enable the PCB detection board 2 to monitor the liquid level 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 adapt to the general shape of the above-mentioned PCB detection board 2, the hollow bracket 3 extends along the height direction of 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 Fig.21 In the illustrated embodiment, the hollow bracket 3 includes two first brackets 31 which are arranged at its edge and extend in the height direction and are interconnected. The PCB detection board 2 is located between the two first brackets 31. A limiting rib 39 is provided on the hollow bracket 3 for limiting the radial movement of the PCB detection board 2 along the glass pot body 1. It can be understood that the limiting rib 39 serves to limit the PCB detection board 2 from detaching from the glass pot body 1. In the present embodiment, the limiting rib 39 is provided as a vertical rib 332 and three transverse ribs 331, wherein the transverse rib 331 also serves to connect the two first brackets 31. Of course, the number of vertical ribs 332 and transverse ribs 331 can be selected according to specific needs, or only the transverse rib 331 or only the vertical rib 332 can be selected. This patent specification will be further elaborated later.
[0057] In this embodiment, in order to fix the PCB detection board 2 and the two first brackets 31 to the glass pot body, the width of the PCB detection board 2 can be set to be smaller than the width of the hollow bracket 3 along the circumferential direction of the glass pot body 1, so that the two sides of the PCB detection board 2 respectively have a radially penetrating first gap 51 with the two first brackets 31, that is, the width of the PCB detection board 2 is set to be smaller than the distance between the two first brackets 31; a fixing glue is set in the first gap 51, and the PCB detection board 2 and the hollow bracket 3 are then adhered together by the fixing glue, so that the PCB detection board 2 and the first bracket 31 are strengthened and fixed. It can be understood 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 with (adhered to) 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 kettle body 1 in the radial direction, so that the fixing glue connects the PCB detection board 2, the hollow bracket 3 and the glass kettle body 1 into one body, 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 processes and accelerated production efficiency. In addition, the fixing glue in the first gap can also play a sealing role.
[0058] On the one hand, the width of the PCB detection board 2 is smaller than the width of the hollow bracket 3, so that there can be a gap between the PCB detection board 2 and the hollow bracket 3; on the other hand, the PCB detection board 2 can be limited by the mold in the process or by the hollow bracket 3, so that the two sides of the PCB detection board 2 and the hollow bracket 3 have radially penetrating first gaps 51 with 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 detection 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, along the circumferential direction of the pot body, the width of the PCB detection board 2 is set to be smaller than the width of the hollow bracket 3, and a first isolation rib 34 is set 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 direction 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 setting the first isolation rib 34 on the hollow bracket 3, the first isolation rib 34 fits with the side of the PCB detection board 2, directly limiting the movement of the detection board along the circumferential direction 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 ribs 34 are arranged on the hollow bracket 3 by an integral molding method, 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. Fig.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 relatively convenient and fast. Of course, the way the first isolation rib 34 and the first bracket 31 are connected in parts such as adhesion, based on the utility model intention of this patent, the above-mentioned implementation method should also be within the scope of protection requested by this patent.
[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 amount of glue 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 ribs 34 of the same size. Of course, those skilled in the art can adjust the size of the first isolation rib 34 or the width of the first gap 51 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, the second brackets 32 are connected to both ends of the first bracket 31, and the first bracket 31 and the second bracket 32 together constitute the edge of the hollow bracket 3, that is, two first brackets 31 and two second brackets 32 are used to enclose and form a frame structure, and the PCB detection board 2 is confined within the frame. The two first brackets 31 limit the PCB detection board 2 in the circumferential direction (along the circumferential direction of the glass kettle body 1), and the two second brackets 32 limit the PCB detection board 2 in the axial direction (along the height direction of the glass kettle body 1), which is conducive to improving the efficiency of the PCB detection board 2 during the installation process.
[0062] It is understandable that a third gap 53 may 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.
[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 Fig.15 and Fig.17 As shown), of course, the second bracket 32 may not be provided (as shown Fig.14 and Fig.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 that is opposite to the glass pot body 1, and the PCB detection board 2 and the limiting rib 39 in this embodiment are also connected by the fixing glue.
[0065] Specifically, a vertical rib 332 and three horizontal ribs 331 divide the hollow bracket 3 into a plurality of glue-filled grids 36 in a crisscross manner, and then the glue is filled with fixing glue, and the PCB detection board 2 is also connected to the vertical rib 332 and three horizontal ribs 331 by fixing glue. In this way, the surrounding side of the PCB detection board 2 can be completely sealed by the fixing glue, so that it is difficult for liquid or water vapor to enter the side of the PCB detection board 2 facing the glass pot body 1 along the surrounding side of the PCB detection 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. In the process of installing 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 detaching 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.
[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 ribs 39 limit 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 found that if too much fixing glue is poured, the fixing glue is easy to overflow from the part where the two parts are attached to the outside of the hollow bracket 3 and enter the glass kettle body 1. Since the overflowing fixing glue is not completely dried, other parts will contact the overflowing fixing glue during the installation process and may adhere to the glass kettle body 1. In addition, the fixing glue overflowing on the glass kettle body 1 is difficult to clean, which affects the overall appearance of the liquid heating container. When the thickness of the PCB detection board 2 is not greater than the depth of the groove 38, the role of the groove 38 is not only to improve the convenience of assembly before placement, that is, the PCB detection board 2 can be completely embedded in the groove 38. In this way, the PCB detection board 2 is not easy to fall out of the hollow bracket 3, and the first bracket 31 and the second bracket 32 facing the glass kettle body 1 can be closer to the outer wall of the glass kettle body 1, which can better solve the problem of the fixing glue in the first gap 51 overflowing from the position 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 an arc-shaped outer wall 11, in order to make the hollow bracket 3 and the arc-shaped outer wall 11 fit more closely 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 arc-shaped outer wall 11 is an arc-shaped surface 311. At this time, when the hollow bracket 3 is pressed against the glass pot body 1, the arc-shaped surface 311 and the arc-shaped outer wall 11 fit more closely, achieving the purpose of no gap or insufficient gap to prevent the 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 arc-shaped 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, and the stability and accuracy of the signal obtained by the PCB detection board 2 will be greatly improved, which also ensures the consistency of signal detection of the same batch of PCB detection boards 2 (used on different machines). Similarly, when there is a second bracket 32, the PCB detection board 2 can also be arranged 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 PCB detection board 2 in the circumferential direction of 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 the product, 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 (easy to break) by cutting thin, and even if it can be achieved by a concave method, it will affect the appearance of the pot body. The applicant has 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 of the same shape, there is a better effect. In this embodiment, the glass pot body 1 includes an arc-shaped outer wall 11, and the PCB detection board 2 is installed on the arc-shaped outer wall 11. The side of the PCB detection board 2 facing the arc-shaped outer wall 11 is a plane, and 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 the above scheme 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 depth of the groove 38 is greater than the thickness of the PCB detection board 2, the arcuate outer wall 11 and the hollow bracket 3 clamp the PCB detection board 2, and the arcuate outer wall 11 convexly faces the groove 38 so that the arcuate outer wall and the middle part of the PCB detection board 2 fit better, thereby better solving the problem of limiting 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, in order to more conveniently position the hollow bracket 3 on the outer wall of the glass pot body 1, a connecting glue such as 3M glue, double-sided tape, etc. can be pasted on the arc surface 311 in advance, and the hollow bracket 3 is directly bonded to the glass pot body 1 through the connecting glue, which plays a role in positioning the hollow bracket 3, and the connecting glue will not flow at will, affecting the appearance. After the PCB detection board 2 is inserted into the hollow bracket 3, the hollow bracket 3 is first fixed to the glass pot body 1 through the connecting glue. After the hollow bracket 3 is fixed, the fixing glue is poured into the hollow bracket 3.
[0074] In this embodiment, the electronic component 21 is arranged below the PCB detection board 2 which is away from the glass kettle body 1, and the hollow bracket 3 forms a hollow and closed anti-overflow frame 37, and the anti-overflow frame 37 is arranged around the outer edge of the electronic component 21. One end of the PCB detection 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 detection board 2 is completely extended into the groove 38, and a wire is arranged on the electronic component 21, and the wire extends out of the anti-overflow frame 37 and extends to the bottom of the glass kettle body 1.
[0075] The electronic component 21 may include a control chip and a wiring port, etc. If the electronic component 21 works in a humid environment for a long time, it will affect the speed and service life of the electronic component 21 operation. 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. Especially for the control chip, if the semiconductor and other materials inside are in contact with water vapor for a long time, it will cause damage to it. Therefore, an anti-overflow frame 37 is set on the hollow bracket 3 to surround the electronic component 21 and form a segment 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 to other areas of the PCB detection board 2, so that the electronic component 21 is covered with the fixing glue, and the control chip can be completely covered with the fixing glue. Thereby, the function of quickly pouring the fixing glue in the electronic component 21 area can be met, and the electronic component 21 can also be placed in a closed environment to prevent contact between water vapor and the electronic component 21.
[0076] In another embodiment, if Fig.14 , Fig.16 As shown, the hollow bracket 3 has no second bracket 32, and the limiting rib 39 can be one or more transverse ribs 331 that transversely connect the two first brackets 31. At this time, 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, if Fig.15 and Fig.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, such as Fig.15 As shown, the vertical ribs 332 extending in the longitudinal direction and connected to the horizontal ribs 331, wherein one end of the vertical ribs 332 can be suspended. Of course, those skilled in the art can also understand that in the case of horizontal ribs, there can be no vertical ribs 332.
[0078] In another embodiment, if Fig.19 As shown, when the first brackets 331 do not need to be connected, the limiting rib 39 is a suspended horizontal 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. Fig.18 As shown, the limiting rib 3 is a vertical rib extending along the longitudinal direction to connect the two second brackets 32. Fig. 20 As shown, the limiting rib 39 is a suspended vertical rib extending from the side wall of the second bracket 32 to the hollow area of the hollow bracket 3; or, the limiting rib 39 extends obliquely from the side wall of the first bracket 31 to the side wall of the second bracket 32. Of course, those skilled in the art can also understand that in the case of vertical ribs, there can be no horizontal ribs.
[0080] It is understandable 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. Fig. 20 As shown, in order to further improve the strength of the limiting rib 39 on the length direction of the PCB detection board 2, the limiting rib 39 is arranged on the second bracket 32, the width of the limiting rib 39 is substantially 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, and the strength of the limiting rib 39 on the length direction of the PCB detection board 2 is improved by increasing the width of the limiting rib 39.
[0082] In another embodiment, if Fig. 20 and Fig. 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 ( Fig. 22The first isolation rib 34 and the second isolation rib 35 of the second bracket 32 are arranged on the side wall of the first bracket 31, and the first isolation rib 34 and the second isolation rib 35 of the second bracket 32 are arranged 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 arranged 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 are arranged on the side wall of the first bracket 31 and the limiting rib 39 are arranged on both sides of the limiting rib 39, and 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 can understand that various forms of limiting ribs 39 such as suspended vertical ribs, vertical ribs 332, transverse ribs 331, suspended transverse ribs, etc. in this patent can be arbitrarily combined according to needs.
[0084] In the above embodiments, those skilled in the art may understand 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) connected to the first bracket 31, wherein the connecting rib may be located in the middle of the first bracket 31, the connecting rib may be one or more, and specifically, the connecting rib is located on the side of the PCB detection board 2 away from the glass pot body 1, 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 also includes a handle 4, and the handle 4 can be connected to the glass kettle body 1 by hooking or by an annular clamp. The handle 4 can be installed at a place corresponding to the hollow bracket 3, or at 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 be without a handle, or the handle is in an arched shape, and the hollow bracket 3 can also be hidden by a shell mounted on the outside of the glass kettle body 1.
[0086] In the above embodiments, in order to prevent consumers from seeing the PCB detection board 2 from the inside of the glass kettle body 1, the glass kettle body 1 can also generally 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, such as ink, at the location where the PCB detection 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 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-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.
[0088] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
