Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a liquid heater. Background Art

[0002] Patent application number CN201720526032.4 discloses a food processor with excellent overflow prevention. By disposing a capacitive sensor plate on the outer wall of the mixing cup that does not contact the food and can sense the height of the food, the water level detection structure ensures that it can accurately monitor the liquid level of the food in the mixing cup and prevent liquid overflow. However, in this structure, the lower end of the handle occupies the vertical installation space outside the mixing cup, causing the bottom end of the existing capacitive sensor plate to be arranged at a position higher than the lower end of the handle to avoid leakage. This raises the lower detection limit of the capacitive sensor plate, resulting in a large detection blind spot at the bottom of the cup body, making it impossible to detect low water level and dry boil.

[0003] To address the aforementioned issues, the applicant has proposed a liquid heater with comprehensive liquid level detection. The device comprises a glass body and a mounting base that fits snugly on the lower portion of the glass body. A first positioning slot and a second positioning slot extending from the first slot to the outer wall of the mounting base are provided on the outer wall of the glass body. The two positioning slots accommodate a detection plate, which is then sealed with glue by filling the positioning slots. This solution allows the detection plate to be installed across the gap between the glass body and the mounting base, expanding the detection area along the height of the glass body and reducing blind spots.

[0004] However, during further research, the applicant discovered that due to errors in the assembly of the mounting base and the glass cup body, the first positioning groove and the second positioning groove were not aligned correctly and a gap was formed, resulting in glue leakage. In addition, an annular gap was naturally formed between the glass cup body and the mounting base, and the glue could leak into the annular gap, causing glue waste. If the glue leaked along the annular gap to between the heating plate and the cup body or between the mating positions of other components, it could cause glue to enter the processing cavity, and after the glue solidified, it would affect the disassembly and assembly of other components, making it difficult to disassemble and repair. Moreover, even if the positioning grooves were formed with the help of the mounting bracket for glue filling, in order to achieve the installation of the detection plate and the glass cup body, the outer side of the mounting base needed to be lower than the outer side of the glass cup body, otherwise interference would occur. In the case where the glass cup body and the cup base are in a socketed relationship and the processing accuracy of the cup base is limited, the mounting bracket and the cup base cannot achieve zero matching, which in turn causes a gap between the cup base and the mounting bracket, resulting in glue leakage. Utility Model Content

[0005] The utility model provides a liquid heater, which solves the glue leakage problem caused by glue filling and fixing the detection plate when the detection plate is installed across the gap between the glass cup body and the cup base.

[0006] The technical solution adopted by this utility model is:

[0007] The utility model provides a liquid heater, comprising a glass cup body and a strip-shaped detection plate for detecting liquid levels in the air, the detection plate being vertically mounted on the peripheral wall of the glass cup body, the liquid heater also comprising a cup base sleeved under the glass cup body and a mounting bracket fixed to the outside of the glass cup body, the mounting bracket being tightly fitted with the outer side surface of the glass cup body to enclose and form a glue pouring groove for accommodating the detection plate, the lower end of the mounting bracket extending to the outside of the cup base, and a baffle being provided on the side of the mounting bracket facing the cup base, the baffle extending upward from the lower end of the mounting bracket to fit with the outer side surface of the glass cup body.

[0008] The liquid heater provided by the present invention is provided with a mounting bracket, and the mounting bracket is tightly matched with the outer side surface of the glass cup body to form a glue pouring groove for accommodating the detection plate. By pouring glue into the glue pouring groove to encapsulate the detection plate, the detection plate is reliably positioned on the outside of the glass cup body to realize air-space liquid level detection. The upper end of the mounting bracket corresponds to the glass cup body and is tightly matched with the outer side surface of the glass cup body to form a glue pouring groove. The lower end of the mounting bracket extends to the outside of the cup base and is provided with a baffle. The baffle makes the glue pouring groove form a closed structure that does not leak glue, which has a good stopping effect during the glue pouring process. The baffle extends upward from the lower end of the mounting bracket to fit with the outer side surface of the glass cup body, thereby spanning the annular fitting gap formed between the glass cup body and the cup base, and shielding the fitting gap to prevent glue from entering the annular gap during the glue pouring process, which saves glue and saves costs, and prevents glue from flowing along the annular gap to the fitting position of other components and affecting the disassembly and maintenance of the liquid heater.

[0009] Therefore, the present application effectively prevents glue from leaking from the gap between the mounting bracket and the glass cup body, the fitting gap between the glass cup body and the cup base, and the gap between the mounting bracket and the cup base, effectively solving the problems of difficult cleaning after glue leakage, glue waste, and impact on the disassembly and assembly of the entire machine, realizing the effective use of glue, and improving the efficiency of assembly, so that the detection board can be quickly packaged in the glue filling tank.

[0010] In addition, since the mounting bracket extends to the outside of the cup base, the accommodating area of the detection board is larger, so as to accommodate a larger detection board, which is conducive to expanding the detection area of the detection board, reducing the detection blind area, and realizing comprehensive detection.

[0011] In a preferred embodiment, a transversely extending retaining rib is protruded from a side of the baffle facing the glass body, and the baffle is fitted with the outer side surface of the glass body through the retaining rib.

[0012] By protruding a transversely extending rib on the side of the baffle facing the glass cup body, the rib can laterally block the gap between the mounting bracket and the cup base, and the baffle is fitted with the outer side surface of the glass cup body through the rib. Compared with direct fitting of the baffle, the contact area can be reduced, a line sealing effect is achieved, and the glue is effectively prevented from leaking into the gap between the mounting bracket and the cup base.

[0013] More preferably, an annular fitting gap is formed between the upper end of the cup base and the outer side surface of the glass cup body, and the retaining rib extends into the fitting gap.

[0014] By extending the retaining rib into the fitting gap, rational use of space is achieved. The retaining rib and the outer side surface of the glass cup body are lengthened along the vertical fitting path, thereby increasing the difficulty of the glue liquid flowing downward through the fitting gap, thereby solving the glue leakage problem.

[0015] In a preferred embodiment, the mounting bracket includes a fitting portion and a mounting portion, the fitting portion is provided with an adhesive layer that fits the glass body, and the baffle is provided at the mounting portion and extends to the adhesive layer.

[0016] The mounting bracket is provided with a fitting portion, and an adhesive layer that fits the glass body is provided on the fitting portion, thereby achieving a reliable connection with the glass body and effectively avoiding a gap between the mounting bracket and the outer side of the glass body, preventing the glue from flowing out of the glue filling tank, effectively utilizing the glue and solving the problems of difficult cleaning and glue waste after glue overflow. The baffle is provided on the mounting portion and extends to the adhesive layer, achieving a seamless connection.

[0017] In a preferred embodiment, an inwardly recessed groove is provided on the outer side surface of the cup base, and the baffle is located in the groove.

[0018] By setting an inwardly recessed groove on the outer side of the cup base, on the one hand, the height difference between the outer side of the cup base and the outer side of the glass can be increased, thereby avoiding the situation where the installation bracket and the detection plate are lifted up by the cup base and cannot be installed in place; on the other hand, the baffle is located in the groove and can use the side wall of the groove to limit the horizontal position, thereby avoiding the deviation of the installation bracket and the detection plate, so that the installation position of the detection plate is accurate and the detection is reliable.

[0019] In a preferred embodiment, a transversely extending limiting rib is convexly provided on the outer side surface of the cup base, and the lower end of the mounting bracket abuts against the limiting rib to be positioned on the outer side of the glass cup body.

[0020] By setting the limiting ribs, the lower end of the mounting bracket is in contact with the limiting ribs and then fixed to the glass cup body using the upper adhesive layer. The limiting ribs realize pre-positioning of the mounting bracket, and realize accurate installation of the mounting bracket. At the same time, the mounting bracket is supported after being fixed to prevent the mounting bracket from falling, and the structure is reliable.

[0021] More preferably, the liquid heater further comprises a protective sleeve, which sleeves the limiting rib and the mounting bracket together.

[0022] By providing a protective sleeve and utilizing the protective sleeve to sleeve the limiting rib and the mounting bracket together, secondary fixation of the mounting bracket and the limiting rib is achieved.

[0023] In a preferred embodiment, a buffer pad is provided between the cup base and the baffle, and the baffle is in contact with the outer side of the buffer pad.

[0024] By providing a cushion and having the baffle plate fit against the outside of the cushion, the cushion can support the mounting bracket through the baffle plate, preventing the lower end of the mounting bracket from being suspended in the air. This prevents the lower end of the mounting bracket from tilting when subjected to force, thus achieving structural stability. Furthermore, since the cup base typically supports the heating plate, heat transfer from the heating plate occurs, so the cushion also acts as a thermal insulator, reducing heat transfer to the mounting bracket and detection plate.

[0025] In a preferred embodiment, the baffle is integrally formed with the mounting bracket;

[0026] Alternatively, the baffle is detachably adhered to the mounting bracket.

[0027] By integrally molding the baffle onto the mounting bracket, assembly time can be saved. By detachably attaching the baffle to the mounting bracket, the size of the baffle can be flexibly selected according to the size of the glass cup body and the cup base, thereby reliably blocking each gap and avoiding glue leakage during the glue filling process.

[0028] In a preferred embodiment, the mounting bracket is provided with a snap button that cooperates with the edge of the detection plate to limit the position;

[0029] By setting the spring buckle, after the detection plate is installed in the preset position, the detection plate is limited by the spring buckle, which is simple and quick to operate, saves time and effort, and improves the assembly efficiency of the detection plate. The detection plate is positioned by the spring buckle to achieve mechanical fixation, reducing the impact of the glass cup body being in a heated environment for a long time on the fixation reliability of the detection plate, making the fixation of the detection plate reliable and durable, and effectively preventing the detection plate from falling off or loosening.

[0030] In a preferred embodiment, the glue pouring tank is provided with a first glue pouring layer formed by glue pouring before the detection board is installed, and the detection board is attached to the surface of the first glue pouring layer. The glue pouring tank is also provided with a second glue pouring layer formed by glue pouring on the outside of the detection board after the detection board is installed.

[0031] By arranging a first glue layer formed by glue filling before the installation of the detection plate in the glue filling groove, the glue forming the first glue layer will not be disturbed by the detection plate during the circulation process, the exhaust is smooth, and the glue flows smoothly, thereby effectively avoiding the generation of bubbles, and further avoiding the bubbles with impurities such as water droplets from affecting the detection. At the same time, in the absence of interference from the detection plate, the glue flows quickly, avoiding the situation where the glue solidifies before it circulates into place, so that the glue can fully fill the gap between the detection plate and the glass cup body, and the detection plate is attached to the surface of the first glue layer, making the first glue layer tight, further avoiding the generation of gaps between the detection plate and the glass cup body. On the one hand, it prevents condensed water from entering the gap and affecting the accuracy of the detection. On the other hand, it can make the detection board stable after positioning and achieve reliable positioning. Therefore, the first glue layer formed before the detection board is installed can effectively improve the detection accuracy of the detection board and further improve the positioning stability and reliability of the detection board; by arranging a second glue layer in the glue pouring groove to form glue on the outside of the detection board after the detection board is installed, the second glue pouring layer is used to effectively seal the outside of the detection board away from the glass cup body, avoiding water vapor from damaging the detection board or affecting the detection of the detection board, thereby improving the detection accuracy of the detection board and extending the service life of the detection board.

[0046] like Figure 1-6 As shown, the present invention provides a liquid heater in a preferred embodiment, including a cup body assembly and a cup cover 11. The cup body assembly includes a glass cup body 10 and a strip-shaped detection plate 20 for detecting the liquid level in the air. The detection plate 20 is vertically installed on the peripheral wall of the glass cup body 10. The liquid heater also includes a cup base 30 sleeved under the glass cup body 10 and a mounting bracket 40 fixed to the outside of the glass cup body. The upper cover of the glass cup body 10 is provided with a cup cover 11. The mounting bracket 40 is tightly matched with the outer side of the glass cup body 10 to enclose a glue pouring groove for accommodating the detection plate 20. The lower end of the mounting bracket 40 extends to the outside of the cup base 30. Figure 2 、 3 As shown in FIG. 4 , a baffle 70 is provided on the side of the mounting bracket 40 facing the cup base 30 . The baffle 70 extends upward from the lower end of the mounting bracket 40 to fit the outer side surface of the glass cup body 10 .

[0047] The liquid heater provided by the present invention is provided with a mounting bracket 40, which is tightly matched with the outer side surface of the glass cup body to form a glue pouring groove for accommodating the detection plate 20. By pouring glue into the glue pouring groove to encapsulate the detection plate, the detection plate is reliably positioned on the outside of the glass cup body to realize air-space liquid level detection. The upper end of the mounting bracket 40 corresponds to the glass cup body and is tightly matched with the outer side surface of the glass cup body to form a glue pouring groove. The lower end of the mounting bracket extends to the outside of the cup base and is provided with a baffle 70. The baffle 70 makes the glue pouring groove form a closed structure that does not leak glue, which plays a good stopping effect during the glue pouring process. The baffle 70 extends upward from the lower end of the mounting bracket 40 to fit with the outer side surface of the glass cup body, thereby spanning the annular fitting gap formed between the glass cup body and the cup base, and shielding the fitting gap to prevent glue from entering the annular gap during the glue pouring process, which saves glue and saves costs, and prevents glue from flowing along the annular gap to the fitting positions of other components and affecting the disassembly and maintenance of the liquid heater.

[0048] Therefore, the present application effectively prevents glue from leaking from the gap between the mounting bracket and the glass cup body, the fitting gap between the glass cup body and the cup base, and the gap between the mounting bracket and the cup base, effectively solving the problems of difficult cleaning after glue leakage, glue waste, and impact on the disassembly and assembly of the entire machine, realizing the effective use of glue, and improving the efficiency of assembly, so that the detection board can be quickly packaged in the glue filling tank.

[0049] In addition, since the mounting bracket extends to the outside of the cup base, the accommodating area of the detection board is larger, so as to accommodate a larger detection board, which is conducive to expanding the detection area of the detection board, reducing the detection blind area, and realizing comprehensive detection.

[0050] In a preferred embodiment, Figure 2 As shown, a side of the baffle 70 facing the glass body 10 is provided with a transversely extending baffle 71, and the baffle 70 is fitted with the outer side of the glass body 10 through the baffle 71. More preferably, as Figure 3 As shown, an annular fitting gap is formed between the upper end of the cup base 30 and the outer side surface of the glass cup body 10, and the retaining rib 71 extends into the fitting gap. More preferably, an elastic member or a sealing ring 12 is provided in the gap to achieve an interference fit between the interference retaining rib 71 and the fitting gap.

[0051] By protruding a transversely extending rib 71 on the side of the baffle 70 facing the glass cup body 10, the rib 71 can laterally block the gap between the mounting bracket 40 and the cup base 30, and the baffle 70 is fitted with the outer side surface of the glass cup body 10 through the rib 71. Compared with direct fitting of the baffle 70, the contact area can be reduced, a line sealing effect can be achieved, and the glue can be effectively prevented from leaking into the gap between the mounting bracket 40 and the cup base 30.

[0052] By extending the retaining rib 71 into the fitting gap, rational use of space is achieved. The retaining rib 71 and the outer side surface of the glass cup body 10 have a longer side length along the vertical fitting path, thereby increasing the difficulty of the glue liquid flowing downward through the fitting gap, thereby solving the glue leakage problem.

[0053] In a preferred embodiment, Figure 2 As shown, the mounting bracket 40 includes a fitting portion 41 and a mounting portion 42. The fitting portion 41 is provided with an adhesive layer 43 that fits the glass body 10. The baffle 70 is provided on the mounting portion 42 and extends to the adhesive layer 43. Optionally, the baffle extends to the adhesive layer, that is, it is connected to the adhesive layer, and the baffle is directly fitted to the glass body; or, as shown in FIG. Figure 3 As shown, the baffle extends to overlap with the adhesive layer, that is, the baffle is adhered to the glass body through the adhesive layer.

[0054] The mounting bracket 40 is provided with a fitting portion 41, and an adhesive layer 43 is provided on the fitting portion 41 to fit the glass body 10, thereby achieving a reliable connection with the glass body 10 and effectively avoiding a gap between the mounting bracket 40 and the outer side of the glass body 10, preventing the glue from flowing out of the glue filling tank, effectively utilizing the glue and solving the problems of difficult cleaning and glue waste after glue overflow. The baffle 70 is provided on the mounting portion 42 and extends to the adhesive layer 43, achieving a seamless connection.

[0055] Of course, it should be noted that the structure of the baffle 70 is not limited to the above-mentioned one. In fact, in another embodiment, the adhesive layer 43 covers both the side of the mounting bracket 40 facing the glass cup body 10 and the side of the baffle 70, so that the baffle 70 is adhered to the mounting seat.

[0056] In a preferred embodiment, Figure 5 As shown, an inwardly recessed groove 32 is provided on the outer side of the cup base 30 , and the baffle 70 is located in the groove 32 .

[0057] More preferably, an extension rib 34 extending along the wall of the sink is convexly provided on the outer side surface of the cup base 30 , and the extension rib 34 radially protrudes from the mounting bracket 40 to strengthen the positioning of the mounting bracket 40 .

[0058] By providing an inwardly recessed groove on the outer side of the cup base 30, on the one hand, the height difference between the outer side of the cup base 30 and the outer side of the glass cup body 10 can be enlarged, thereby avoiding the situation where the mounting bracket 40 and the detection plate 20 are lifted up by the cup base 30 and cannot be installed in place; on the other hand, the baffle 70 is located in the groove and can utilize the side wall of the groove for lateral limitation, thereby avoiding the deviation of the mounting bracket 40 and the detection plate 20, so that the installation position of the detection plate 20 is accurate and the detection is reliable.

[0059] Of course, the groove structure is not limited to the above-mentioned one. In another preferred embodiment, two vertically extending ribs are provided on the outer side surface of the cup base 30. The two ribs and the outer side surface of the cup base 30 are combined to form a groove to limit the baffle 70 and the mounting bracket 40.

[0060] In a preferred embodiment, Figure 3 、 5 As shown, a transversely extending limiting rib 31 is convexly provided on the outer side surface of the cup base 30 , and the lower end of the mounting bracket 40 abuts against the limiting rib 31 to be positioned on the outer side of the glass cup body 10 .

[0061] By setting limiting ribs, the lower end of the mounting bracket 40 is in contact with the limiting ribs and then fixed to the glass cup body 10 using the upper adhesive layer 43. The limiting ribs realize pre-positioning of the mounting bracket 40 and accurate installation of the mounting bracket 40. At the same time, after the mounting bracket 40 is fixed, the mounting bracket 40 is supported to prevent the mounting bracket 40 from falling, and the structure is reliable.

[0062] More preferably, if Figure 3 As shown, the liquid heater further comprises a protective sleeve 80, which sleeves the limiting rib 31 and the mounting bracket 40. More preferably, the protective sleeve further comprises a protective surface shielding the outside of the detection plate 20 to further seal and protect the detection plate 20.

[0063] By providing a protective sleeve and utilizing the protective sleeve to sleeve the limiting rib and the mounting bracket 40 together, secondary fixation of the mounting bracket 40 and the limiting rib is achieved.

[0064] In a preferred embodiment, a buffer pad is provided between the cup base 30 and the baffle 70 , and the baffle 70 is in contact with the outer side of the buffer pad.

[0065] By providing a cushion and having the baffle 70 fit against the outside of the cushion, the cushion supports the mounting bracket 40 through the baffle 70, preventing the lower end of the mounting bracket 40 from being suspended in the air. This prevents the lower end of the mounting bracket 40 from tilting when subjected to force, thus achieving structural stability. Furthermore, since the cup base 30 typically supports the heating plate, heat transfer from the heating plate occurs. Therefore, the cushion also acts as a thermal insulator, reducing heat transfer to the mounting bracket 40 and the detection board 20.

[0066] It should be noted that the present invention does not limit the structure of the baffle 70. In a preferred embodiment, the baffle 70 is integrally formed with the mounting bracket 40. In another preferred embodiment, Figure 7 As shown, the baffle 70 is a diaphragm that is detachably adhered to the mounting bracket 40 .

[0067] By integrally forming the baffle 70 on the mounting bracket 40, assembly time can be saved. By detachably adhering the baffle 70 to the mounting bracket 40, the size of the baffle 70 of the appropriate size can be flexibly selected according to the size of the glass cup body 10 and the cup base 30, thereby reliably blocking each gap and avoiding glue leakage during the glue filling process.

[0068] In addition, in order to strengthen the fixation of the detection plate 20 , in a preferred embodiment, a spring buckle 50 is provided on the mounting bracket 40 to cooperate with the edge of the detection plate 20 for limiting the position.

[0069] By setting the spring buckle 50, after the detection plate 20 is installed in the preset position, the detection plate 20 is limited by the spring buckle 50, which is simple and quick to operate, saves time and effort, and improves the assembly efficiency of the detection plate 20. The detection plate 20 is positioned by the spring buckle 50 to achieve mechanical fixation, reducing the impact of the glass cup body 10 being in a heating environment for a long time on the fixation reliability of the detection plate 20, so that the fixation of the detection plate 20 is reliable and durable, and effectively prevents the detection plate 20 from falling off or loosening.

[0070] It should be noted that, in a preferred embodiment, spring clips 50 may be provided on opposite sides of the detection plate 20 on the mounting bracket 40 , and the spring clips 50 clamp the detection plate 20 or press the detection plate 20 against the outer side surface of the detection plate 20 ;

[0071] Alternatively, a spring buckle 50 is provided on one side of the detection board 20 and an elastic member is provided on the other side, and the detection board 20 is positioned in the glue filling groove through the cooperation between the spring buckle 50 and the elastic member.

[0072] In addition, it should be noted that the present invention does not limit the installation order of the detection plate 20. In a preferred embodiment, Figure 6 As shown, a first glue potting layer 61 is provided in the glue potting tank and is formed by glue potting before the detection board 20 is installed. The detection board 20 is attached to the surface of the first glue potting layer 61. A second glue potting layer 62 is also provided in the glue potting tank and is formed by glue potting on the outside of the detection board 20 after the detection board 20 is installed.

[0073] Optionally, the detection board 20 can be supported only by the wall of the glue filling tank and the outer side surface of the glass cup body 10; or limited by the spring buckle 50.

[0074] By arranging a first glue layer 61 formed by glue filling before the detection board 20 is installed in the glue filling groove, the glue forming the first glue layer 61 will not be disturbed by the detection board 20 during the circulation process, the exhaust is smooth, and the glue flows smoothly, thereby effectively avoiding the generation of bubbles, and further avoiding the bubbles with impurities such as water droplets from affecting the detection. At the same time, in the absence of interference from the detection board 20, the glue flows quickly, avoiding the situation where the glue has not yet circulated into place and solidifying, so that the glue can fully fill the gap between the detection board 20 and the glass cup body 10, and the detection board 20 is attached to the surface of the first glue layer 61, so that the first glue layer 61 is compact, further avoiding the generation of gaps between the detection board 20 and the glass cup body 10. On the one hand, it prevents condensed water from entering the gap and affecting the accuracy of the detection. On the other hand, it can make the detection board 20 stable after positioning and achieve reliable positioning. Therefore, the first glue layer 61 formed before the detection board 20 is installed can effectively improve the detection accuracy of the detection board 20 and further improve the positioning stability and reliability of the detection board 20; by setting a second glue layer 62 on the outside of the detection board 20 after the detection board 20 is installed in the glue pouring groove, the second glue layer 62 is used to effectively seal the outside of the detection board 20 away from the glass cup body 10, thereby preventing water vapor from damaging the detection board 20 or affecting the detection of the detection board 20, thereby improving the detection accuracy of the detection board 20 and extending the service life of the detection board 20.

[0075] Of course, in another preferred embodiment, the installation sequence of the detection board 20 is: after fixing the mounting bracket 40 to the glass cup body 10, for example, setting a back glue on the back of the mounting bracket 40 to form an adhesive layer 43 to achieve bonding with the glass cup body 10, and then placing the detection board 20 in the glue pouring tank, and then pouring glue into the glue pouring tank, and after the glue solidifies, encapsulating the detection board 20 in the glue pouring tank.

[0076] The present invention does not limit the structure of the liquid heater.
