Description

Technical Field

[0001] The utility model belongs to the field of drinking water equipment, and particularly relates to a kettle. Background Art

[0002] Currently, kettles on the market usually use floats as liquid level detection devices. However, the floats are very easy to get stuck or blocked by foreign objects, causing the floats to be unable to accurately detect the water level in the kettle.

[0003] Although the use of a capacitance detection plate can detect the liquid level without contacting the liquid, because the outer surface of the kettle is a curved surface and the capacitance detection plate is a flat plate, a gap will be created between the capacitance detection plates. The entry of air with high humidity from the outside into the gap will affect the accuracy of the capacitance detection, making it impossible for the capacitance detection plate to accurately measure the liquid level, resulting in a poor user experience. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a kettle to solve at least one of the above problems.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a kettle comprising a kettle body and a water level detection assembly, the water level detection assembly comprising a capacitor detection plate, a sealing ring, and a support frame. The capacitor detection plate is embedded in the sealing ring, which is bonded to the outer wall of the kettle body. The support frame is mounted on the side of the sealing ring away from the kettle body, so that the two end faces of the sealing ring respectively abut against the kettle body and the support frame. This technical solution has the following technical effects:

[0006] The utility model arranges a water level detection component with a capacitance detection plate on the outside of the kettle body. The capacitance detection plate can measure the height of the liquid level in the kettle by measuring the change in capacitance, so as to realize real-time monitoring of the water level in the kettle without contacting the liquid. The measurement accuracy is high and the failure rate is low. The user can know the water level in the kettle in a timely and accurate manner, and the user experience is good. When installing the water level detection assembly and the kettle body, the capacitor detection plate can be first embedded in the sealing ring, and then the sealing ring can be adhered to the outer wall of the kettle body. Because the capacitor detection is embedded in the sealing ring, the seal between the circumference of the capacitor detection plate and the sealing ring can be effectively guaranteed. Because the sealing ring has good deformation performance, when the outer wall of the kettle body is a curved surface, the sealing ring can be deformed to fit tightly and adhere to the outer wall of the kettle body, avoiding the formation of a gap between the kettle body and the sealing ring, so that the gap formed between the capacitor detection plate and the kettle body can be kept sealed, and the air carrying water vapor from the outside is prevented from entering the gap formed between the capacitor detection plate and the kettle body through the gap between the sealing ring and the kettle body or between the sealing ring and the capacitor detection plate, thereby affecting the detection accuracy of the capacitor detection plate. There is no need to inject colloid into the gap formed between the capacitor detection plate and the kettle body. While the installation is simple and convenient, it also avoids a large number of bubbles generated during the injection of colloid from affecting the detection results of the capacitor detection plate, thereby ensuring that the capacitor detection plate accurately detects the water level in the kettle body.

[0007] In the kettle described above, the sealing ring is provided with a mounting groove opening toward the kettle body, and the capacitance detection plate is disposed within the mounting groove. The peripheral side of the capacitance detection plate is disposed within the mounting groove and abuts against the inner wall of the mounting groove, thereby enabling rapid installation and positioning of the capacitance detection plate and the sealing ring, thereby reducing assembly difficulty.

[0008] In the aforementioned kettle, two opposing inner sidewalls of the mounting slot are provided with retaining ribs. The retaining ribs abut against the side of the capacitor detection plate facing the kettle body to press the capacitor detection plate firmly into the mounting slot. The retaining ribs press the capacitor detection plate firmly into the mounting slot to limit the position of the capacitor detection plate, thereby preventing the capacitor detection plate from freely disengaging from the sealing ring and ensuring that the capacitor detection plate remains stable for detecting the water level in the kettle body.

[0009] In the kettle described above, the limiting rib is flush with the end face of the sealing ring, so that the limiting rib and the end face of the sealing ring can be bonded to the kettle body together. This allows the limiting rib and the end face of the sealing ring to be bonded to the kettle body, thereby increasing the contact area between the sealing ring and the kettle body, further enhancing the sealing between the sealing ring and the kettle body, and preventing air carrying water vapor from entering the capacitor detection board through the gap between the sealing ring and the kettle body, thereby affecting the capacitor detection board's accurate detection of the water level.

[0010] In the aforementioned kettle, the sealing ring includes an inner ring body embedded with a capacitor detection plate, and the support frame includes a support frame having a support groove formed therein, with the side of the inner ring body facing away from the kettle body embedded in the support groove. The side of the inner ring body facing away from the kettle body is embedded in the support groove to facilitate installation and positioning of the inner ring body and the support frame. This allows for quick installation and positioning of the inner ring body and the support frame via the support groove, reducing assembly difficulty. Furthermore, the support frame supports the inner ring body to prevent the inner ring body from freely deforming around the capacitor detection plate and becoming detached from the kettle, thereby enhancing the seal between the inner ring body and the kettle body and ensuring stable detection of the water level within the kettle by the capacitor detection plate.

[0011] In the aforementioned kettle, the sealing ring further includes an outer ring disposed around the inner ring, a gap for glue injection formed between the inner and outer rings, and a plurality of connecting ribs for connecting the inner and outer rings are disposed within the gap for glue injection. The outer ring increases the bonding area between the sealing ring and the kettle body, thereby enhancing the sealing between the two bodies. After the sealing ring is installed on the kettle body, glue is injected into the gap for glue injection between the inner and outer rings. After the glue solidifies, the contact area between the sealing ring and the kettle body support is further increased. Simultaneously, the support frame is fixed to the sealing ring to achieve a stable connection between the support frame and the sealing ring, prevent the support frame from detaching from the sealing ring, and ensure stable support of the sealing ring by the support frame.

[0012] In the aforementioned kettle, the thickness of the connecting rib is smaller than the depth of the glue gap, so that the glue gaps on both sides of the connecting rib are connected. When the glue is poured into the glue gap, the glue can flow over the connecting rib to the adjacent glue gap. This eliminates the need to pour the glue into each glue gap on both sides of the connecting rib one by one. The glue will automatically level out, reducing the difficulty of glue pouring.

[0013] In the kettle described above, the support frame further includes a plurality of horizontally extending support bars, each end of which is connected to the inner sidewall of the support frame and abuts against the inner ring. The support bars extend horizontally between and connect two opposing inner sidewalls of the support frame to enhance the strength of the support frame. The portions of the support bars protruding from the support frame at both ends abut against the inner ring, facilitating installation between the support frame and the sealing ring. The support frame is also horizontally limited to prevent horizontal shaking of the support frame on the sealing ring.

[0014] In the kettle described above, the sealing ring is a silicone ring or a rubber ring, and the support frame is a hard plastic or metal part. The silicone ring and the rubber ring are soft and have good sealing properties. They are also chemically stable and resistant to aging. When used as sealing rings, they maintain a long-term seal between the sealing ring and the kettle body, making them difficult to disengage. The support frame is a hard plastic or metal part, which facilitates production and processing while providing good support for the sealing ring, further improving the sealing performance between the sealing ring and the kettle body, thereby ensuring that the capacitor detection board can stably detect the water level in the kettle body.

[0015] In the aforementioned kettle, the kettle further includes a mounting frame, which is plugged into the kettle body to position the water level detection assembly during installation. The mounting frame is removed from the kettle body after the water level detection assembly and the kettle body are assembled. When the water level detection assembly needs to be installed on the kettle body, the mounting frame can be first installed on the outer wall of the kettle body, and then the water level detection assembly can be embedded in the area enclosed by the mounting frame. The water level detection assembly is positioned on the outer wall of the kettle body by abutting against the inner wall of the mounting frame. After the water level detection assembly and the kettle body are assembled, the mounting frame can be removed from the kettle body, thereby reducing the difficulty of assembling the water level detection assembly and improving assembly efficiency.

[0033] The utility model proposes a kettle, including a kettle body and a water level detection component, the water level detection component including a capacitor detection plate, a sealing ring and a support frame, the capacitor detection plate is embedded in the sealing ring, the sealing ring is bonded to the outer wall of the kettle body, and the support frame is installed on the side of the sealing ring away from the kettle body, so that the two end faces of the sealing ring are respectively against the kettle body and the support frame. The utility model arranges a water level detection component with a capacitor detection plate on the outside of the kettle body. The capacitor detection plate can measure the height of the liquid in the kettle by measuring the change in capacitance, and can realize real-time monitoring of the water level in the kettle without contacting the liquid. The measurement accuracy is high and the failure rate is low. The user can know the water level in the kettle in a timely and accurate manner, and the user experience is good. When installing the water level detection assembly and the kettle body, the capacitor detection plate can be first embedded in the sealing ring, and then the sealing ring can be adhered to the outer wall of the kettle body. Because the capacitor detection is embedded in the sealing ring, the seal between the circumference of the capacitor detection plate and the sealing ring can be effectively guaranteed. Because the sealing ring has good deformation performance, when the outer wall of the kettle body is a curved surface, the sealing ring can be deformed to fit tightly and adhere to the outer wall of the kettle body, avoiding the formation of a gap between the kettle body and the sealing ring, so that the gap formed between the capacitor detection plate and the kettle body can be kept sealed, and the air carrying water vapor from the outside is prevented from entering the gap formed between the capacitor detection plate and the kettle body through the gap between the sealing ring and the kettle body or between the sealing ring and the capacitor detection plate, thereby affecting the detection accuracy of the capacitor detection plate. There is no need to inject colloid into the gap formed between the capacitor detection plate and the kettle body. While the installation is simple and convenient, it also avoids a large number of bubbles generated during the injection of colloid from affecting the detection results of the capacitor detection plate, thereby ensuring that the capacitor detection plate accurately detects the water level in the kettle body.

[0039] Example 1:

[0040] A kettle, such as Figures 1 to 7As shown, the kettle body 100 and the water level detection assembly 200 are provided on the outer wall of the kettle body 100 for detecting the water level in the kettle body 100. The water level detection assembly 200 includes a capacitance detection plate 300, a sealing ring 400 and a support frame 500. The capacitance detection plate 300 is embedded in the sealing ring 400 so that the sealing ring 400 surrounds the capacitance detection plate 300. The sealing ring 400 is adhered to the outer wall of the kettle body 100 by a sticky material such as a double-sided tape 700. The support frame 500 is installed on the side of the sealing ring 400 away from the kettle body 100 so that the two end faces of the sealing ring 400 are respectively against the kettle body 100 and the support frame 500. The capacitance detection plate 300 measures the height of the liquid in the kettle body 100 by measuring the change in capacitance. When the liquid level rises, the total dielectric constant value between the two electrodes of the capacitance detection plate 300 increases accordingly, thereby increasing the capacitance. Conversely, when the liquid level drops, the total dielectric constant value between the two electrodes of the capacitance detection plate 300 decreases accordingly, thereby decreasing the capacitance.

[0041] The utility model sets a water level detection component 200 with a capacitance detection plate 300 on the outside of the kettle body 100. The capacitance detection plate 300 can measure the height of the liquid level in the kettle body 100 by measuring the change in capacitance, so as to realize real-time monitoring of the water level in the kettle without contacting the liquid. The measurement accuracy is high and the failure rate is low. The user can know the water level in the kettle in a timely and accurate manner, and the user experience is good. When installing the water level detection component 200 and the kettle body 100, the capacitor detection plate 300 can be first embedded in the sealing ring 400, and then the sealing ring 400 can be bonded to the outer wall of the kettle body 100. Because the capacitor detection is embedded in the sealing ring 400, the seal between the peripheral side of the capacitor detection plate 300 and the sealing ring 400 can be effectively guaranteed. Moreover, because the sealing ring 400 has good deformation performance, when the outer wall of the kettle body 100 is a curved surface, the sealing ring 400 can be deformed to fit tightly and bonded to the outer wall of the kettle body 100, avoiding the generation of a gap between the kettle body 100 and the sealing ring 400, so that the capacitor detection plate 300 can be effectively sealed. The gap formed between 300 and the kettle body 100 can be kept sealed, preventing air carrying water vapor from the outside from entering the gap formed between the capacitor detection plate 300 and the kettle body 100 through the sealing ring 400 and the kettle body 100 or between the sealing ring 400 and the capacitor detection plate 300, thereby affecting the detection accuracy of the capacitor detection plate 300. There is no need to inject colloid into the gap formed between the capacitor detection plate 300 and the kettle body 100. While the installation is simple and convenient, it also avoids a large number of bubbles generated when injecting colloid to affect the detection results of the capacitor detection plate 300, thereby ensuring that the capacitor detection plate 300 accurately detects the water level in the kettle body 100.

[0042] like Figure 6 and Figure 7As shown, a mounting groove 411 with an opening toward the kettle body 100 is provided on the sealing ring 400. The peripheral side of the capacitance detection plate 300 is disposed within the mounting groove 411 and abuts against the inner wall of the mounting groove 411, thereby enabling quick installation and positioning between the capacitance detection plate 300 and the sealing ring 400, reducing assembly difficulty. Positioning ribs 412 are provided on two opposing inner sidewalls of the mounting groove 411. The side of the capacitance detection plate 300 facing away from the kettle body 100 abuts against the inner wall of the mounting groove 411, while the side of the capacitance detection plate 300 facing the kettle body 100 abuts against the position-limiting ribs 412. The position-limiting ribs 412 press the capacitance detection plate 300 tightly into the mounting groove 411 to limit the capacitance detection plate 300, thereby preventing the capacitance detection plate 300 from freely detaching from the sealing ring 400 and ensuring that the capacitance detection plate 300 can remain stable outside the kettle body, thereby stably detecting the water level within the kettle body 100. Preferably, the limiting rib 412 is provided on the inner circumferential side of the sealing ring 400 close to the kettle body 100, and the end face of the limiting rib 412 is flush with the end face of the sealing ring 400 facing the kettle body 100, so that the limiting rib 412 can be bonded to the kettle body 100 together with the end face of the sealing ring 400, so as to increase the contact area between the sealing ring 400 and the kettle body 100, further enhance the sealing between the sealing ring 400 and the kettle body 100, and prevent the air carrying water vapor from the outside from entering the capacitor detection plate 300 through the gap between the sealing ring 400 and the kettle body 100 and affecting the accurate detection of the water level by the capacitor detection plate 300.

[0043] In this embodiment, the sealing ring 400 includes an inner ring body 410 and an outer ring body 420, the capacitance detection plate 300 is embedded in the inner ring body 410, and the support frame 500 includes a support frame 510. Figure 7 As shown, a support groove 511 is provided on the support frame 510, and the side of the inner ring body 410 facing away from the kettle body 100 is embedded in the support groove 511 to install and position the inner ring body 410 and the support frame 510, so that the inner ring body 410 and the support frame 510 can be quickly installed and positioned through the support groove 511, reducing the difficulty of assembly. At the same time, the support frame 510 can support the inner ring body 410 to prevent the inner ring body 410 on the side of the capacitor detection plate 300 from freely deforming and detaching from the kettle, thereby enhancing the seal between the inner ring body 410 and the kettle body 100, and thereby ensuring the stable detection of the water level in the kettle body 100 by the capacitor detection plate 300.

[0044] like Figure 4 and Figure 5As shown, the outer ring body 420 is arranged around the inner ring body 410, and a glue gap 440 is formed between the inner ring body 410 and the outer ring body 420. A plurality of spaced connecting ribs 430 are provided in the glue gap 440. The plurality of connecting ribs 430 are respectively connected between the inner ring body 410 and the outer ring body 420. The outer ring body 420 can increase the bonding area between the sealing ring 400 and the kettle body 100, and enhance the sealing between the sealing ring 400 and the kettle body 100. After being installed on the kettle body 100, colloid is injected into the glue injection gap 440 formed between the inner ring body 410 and the outer ring body 420. After the colloid solidifies, the contact area between the sealing ring 400 and the kettle body 100 bracket can be further increased. At the same time, the support frame 500 is fixed on the sealing ring 400 to achieve a stable connection between the support frame 500 and the sealing ring 400, prevent the support frame 500 from detaching from the sealing ring 400, and ensure that the support frame 500 stably supports the sealing ring 400. Preferably, the thickness of the connecting rib 430 is smaller than the depth of the glue pouring gap 440 so that the glue pouring gaps 440 on both sides of the connecting rib 430 are connected. That is, when pouring colloid into the glue pouring gap 440, the colloid can flow over the connecting rib 430 to the adjacent glue pouring gap 440 position, so that when pouring colloid, there is no need to pour colloid into the glue pouring gap 440 on both sides of each connecting rib 430 one by one. The colloid will automatically level out, reducing the difficulty of pouring colloid.

[0045] In order to enhance the supporting effect of the support frame 500 on the sealing ring 400 and prevent the sealing ring 400 from deforming in the direction away from the kettle body 100 and separating from the kettle body 100, the support frame 500 in this embodiment also includes a plurality of support bars 520, and the plurality of support bars 520 extend horizontally between the two opposite inner side walls of the support frame 510 and are connected to the two to enhance the strength of the support frame 510. The support bar 520 is arranged to protrude from the support frame 510 at one end toward the kettle body 100, and the parts of the support bar 520 protruding from the support frame 510 at both ends are against the inner ring body 410, which facilitates the installation between the support frame 500 and the sealing ring 400. At the same time, the support frame 510 can be limited in the horizontal direction to prevent the support frame 500 from shaking horizontally on the sealing ring 400.

[0046] In this embodiment, it is preferred that the sealing ring 400 is a silicone ring or a rubber ring. The silicone ring and the rubber ring are soft and have good sealing properties. At the same time, they are chemically stable and aging-resistant. When used as the sealing ring 400, the sealing ring 400 and the kettle body 100 can be kept sealed for a long time and are not easy to come off. The support frame 500 is a hard plastic or metal part, which is convenient for the production and processing of the support frame 500. At the same time, it has a good supporting effect on the sealing ring 400, further improving the sealing performance between the sealing ring 400 and the kettle body 100, thereby ensuring that the capacitor detection board 300 can stably detect the water level in the kettle body 100.

[0047] The kettle in this embodiment may further include a mounting frame 600, which is detachably connected to the kettle body 100. When the water level detection assembly 200 needs to be mounted on the kettle body 100, the mounting frame 600 may be detachably connected to the kettle body 100. Figure 2 As shown, the installation frame 600 can be installed on the outer wall of the kettle body 100 first, and then the water level detection component 200 can be embedded in the area surrounded by the installation frame 600. The sealing ring 400 of the water level detection component 200 is abutted against the inner wall of the installation frame 600 to achieve its installation positioning on the outer wall of the kettle body 100. After the water level detection component 200 and the kettle body 100 are assembled, as shown in FIG. Figure 1 As shown, the mounting frame 600 can be removed from the kettle body 100, reducing the difficulty of assembling the water level detection component 200 and improving assembly efficiency. Preferably, a base is provided at the bottom of the kettle body 100, and both the kettle body 100 and the base are provided with a plug-in hole 110. Plug-in protrusions are provided at the upper and lower ends of the mounting frame 600 facing the kettle body 100, respectively. The plug-in protrusions are plugged into the plug-in holes 110 to achieve a detachable connection between the limit frame and the kettle body 100. The structure is simple and easy to install and remove. At the same time, the plug-in hole 110 can also reserve a mounting position for the handle. Of course, it can be understood that the plug-in hole 110 here can be a through hole or a blind hole with one end closed.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
