Description

Technical Field

[0001] This invention belongs to the field of electrical structure technology and relates to a kettle that can be quickly reset. Background Technology

[0002] Kettles are a common type of electrical appliance. Many kettles, such as push-button kettles, start boiling water when the button is pressed. Traditional kettles use a temperature sensor inside to detect the water temperature, and the button resets once the water cools to a certain level. However, because boiling water cools slowly, it takes a long time for the button to reset, meaning it can't immediately start boiling again, failing to meet demand and urgently needing improvement. Summary of the Invention

[0003] The purpose of this invention is to provide a cleverly designed structure that transports water vapor through a steam pipe and then senses the high-temperature water vapor through a temperature sensor. Since there is very little water vapor after the water boils and heating stops, the temperature sensor cools down and resets quickly, allowing the water to boil again quickly. This invention is highly practical.

[0004] The above objective is achieved through the following technical solution: a kettle with quick reset capability, comprising a kettle body, the kettle body having a bottom plate; the kettle body including a water boiling cavity; and a steam pipe disposed within the water boiling cavity;

[0005] The kettle bottom plate includes an upper cover and a lower seat. The upper cover covers the lower seat and forms a kettle bottom cavity. A heating component is provided in the kettle bottom cavity for heating the liquid in the boiling water chamber. A steam interface is also provided in the kettle bottom cavity for connecting a steam pipe.

[0006] The bottom cavity of the kettle is also provided with a pressing component, which includes a pressing plate and a pressing button at the front end of the pressing plate; the pressing button can be pressed down or bounced up to reset; the side of the bottom plate of the kettle is provided with an opening, and the pressing button extends outward from the opening for pressing;

[0007] The pressing assembly also includes a mounting support, a cover plate, and an arc-shaped stop bar; the arc-shaped stop bar has a vertical arc-shaped portion and a bottom baffle; the end of the vertical arc-shaped portion has a stop bar slot;

[0008] The front end of the mounting support is provided with a first arc-shaped part, the arc-shaped baffle is placed at the front end of the first arc-shaped part, and the vertical arc-shaped part and the first arc-shaped part are fitted together;

[0009] The cover plate is provided with a cylindrical interface, which is connected to the steam interface; the cover plate is located above the vertical arc-shaped portion and the first arc-shaped portion; and the cylindrical interface, the vertical arc-shaped portion, and the first arc-shaped portion together form a steam chamber; an elastic temperature sensing plate is provided below the first arc-shaped portion;

[0010] The pressing plate is also provided with a side strip, and the side strip is provided with a buckle protrusion and a buckle groove; the buckle protrusion is placed in the stop strip slot;

[0011] The elastic temperature-sensing sheet has a hollowed-out portion, and an elastic strip is provided in the hollowed-out portion;

[0012] The pressing component is also provided with a rocker plate, and the bottom front side of the rocker plate is provided with a rocker plate protrusion, and the front end of the elastic strip abuts against the rocker plate protrusion.

[0013] The buckle groove is located at the tail end of the pressing plate, and the rear end of the rocker is provided with a rocker boss, which is placed in the buckle groove.

[0014] Furthermore, when the button is pressed down, the arc-shaped stop bar moves downward through the snap-fit ​​protrusion, and the vertical arc-shaped part also moves downward. A gap channel is formed between the lower end of the vertical arc-shaped part and the lower end of the first arc-shaped part. The steam in the water heating chamber flows through the steam pipe, then through the cylindrical interface to the steam chamber, and then through the gap channel to the elastic temperature sensing plate.

[0015] After the elastic strip cools down, it automatically springs back to its original position. After springing back, it pushes the rocker protrusion upward, thereby causing the rocker boss to move downward. The side that presses the buckle groove moves downward, causing the side that presses the button to spring back to its original position.

[0016] Furthermore, the height of the steam pipe is slightly lower than the height of the water boiling chamber inside the kettle.

[0017] Furthermore, the two ends of the vertical arc-shaped portion are respectively provided with retaining strip slots.

[0018] Furthermore, the pressing plate has side strips on both sides, and each side strip has a buckle protrusion, which corresponds to the retaining strip slots at both ends of the vertical arc-shaped part.

[0019] Furthermore, the kettle is also equipped with a kettle stand; the kettle body and the kettle stand are plugged into each other for power supply.

[0020] Furthermore, the pot body is provided with a handle and a spout.

[0021] Furthermore, the spout is a curved, slender spout.

[0022] Furthermore, an installation gap is provided between the pressing button and the vertical arc-shaped part, and a vertical insert strip is also provided at the front end of the cover plate; the vertical insert strip is inserted into the installation gap.

[0023] Furthermore, a semi-circular truncated cone is provided inward at the center of the inner wall of the first arc-shaped portion; a semi-circular circular protrusion is provided outward at the center of the vertical arc-shaped portion; the truncated cone and the circular protrusion are arranged opposite each other on both sides, and the cylindrical interface is located directly above the truncated cone and the circular protrusion.

[0024] In this invention, a steam pipe is installed in the boiling chamber and connected to the cavity of the kettle body. An elastic temperature-sensing plate is installed in the cavity of the kettle body to sense steam. Because there is very little steam after the water boils and boiling stops, the temperature-sensing plate will not sense steam and will cool down quickly. This avoids the long waiting time required for sensors to sense water temperature in traditional kettles. Therefore, in this invention, the elastic temperature-sensing plate quickly rebounds and resets after cooling, causing the button to reset quickly as well, allowing for rapid restarting of the boiling process. This solves the problem of traditional kettle buttons taking a long time to reset. Attached Figure Description

[0042] like Figures 1 to 15 The diagram shown is a structural schematic of the quick-resetting kettle of the present invention. The quick-resetting kettle of the present invention includes a kettle body 1, the kettle body 1 having a bottom plate 13; the kettle body 1 includes a water boiling cavity; a steam pipe 14 is provided inside the water boiling cavity.

[0043] The kettle bottom plate 13 includes an upper cover 131 and a lower seat 132. The upper cover 131 covers the lower seat 132 and forms a kettle bottom cavity 133. A heating component 134 is provided in the kettle bottom cavity 133 for heating the liquid in the boiling water chamber. A steam interface 135 is also provided in the kettle bottom cavity 133 for connecting a steam pipe 14.

[0044] The bottom cavity 133 of the kettle is also provided with a pressing component 2, which includes a pressing plate 21. The front end of the pressing plate 21 is provided with a pressing button 211. The pressing button 211 can be pressed down or bounced up to reset. The side of the bottom plate 13 of the kettle is provided with an opening, and the pressing button 211 extends outward from the opening for pressing.

[0045] The pressing component 2 is also provided with a mounting support 22, a cover plate 23 and an arc-shaped baffle 24; the arc-shaped baffle 24 is provided with a vertical arc-shaped part 241 and a bottom baffle; the end of the vertical arc-shaped part 241 is provided with a baffle slot 242;

[0046] The front end of the mounting support 22 is provided with a first arc-shaped part 221, the arc-shaped baffle 24 is placed at the front end of the first arc-shaped part 221, and the vertical arc-shaped part 241 and the first arc-shaped part 221 are fitted together.

[0047] The cover plate 23 is provided with a cylindrical interface 231, which is connected to the steam interface 135; the cover plate 23 is located above the vertical arc-shaped portion 241 and the first arc-shaped portion 221; and the cylindrical interface 231, the vertical arc-shaped portion 241 and the first arc-shaped portion 221 together form a steam chamber; an elastic temperature sensing sheet 25 is provided below the first arc-shaped portion 221;

[0048] The pressing plate 21 is also provided with a side strip, and the side strip is provided with a buckle protrusion 212 and a buckle groove 213; the buckle protrusion 212 is placed in the stop bar slot 242;

[0049] The elastic temperature sensing sheet 25 is provided with a hollow portion, and an elastic strip 251 is provided in the hollow portion;

[0050] The pressing component 2 is also provided with a rocker plate 27, and the rocker plate 27 has a rocker plate protrusion 271 on the bottom side of its front end, and the front end of the elastic strip 251 abuts against the rocker plate protrusion 271.

[0051] The buckle groove 213 is located at the tail end of the pressing plate 21, and the rear end of the rocker 27 is provided with a rocker boss 272, which is placed in the buckle groove 213.

[0052] In this invention, after the pressing key 211 is pressed downward, the snap-fit ​​protrusion 212 drives the arc-shaped baffle 24 to move downward, and the vertical arc-shaped part 241 also moves downward. A gap channel 26 is formed between the lower end of the vertical arc-shaped part 241 and the lower end of the first arc-shaped part 221. The steam in the water heating chamber flows through the steam pipe 14, then through the cylindrical interface 231 to the steam chamber, and then through the gap channel 26 to the elastic temperature sensing plate 25.

[0053] After the elastic strip 251 cools down, it automatically pops up and resets. After popping up, it pushes the rocker protrusion 271 upward, thereby causing the rocker boss 272 to move downward and press the side of the buckle groove 213 to move downward, causing the side of the pressing button 211 to pop up and reset.

[0054] As a preferred embodiment, the height of the steam pipe 14 is slightly lower than the height of the boiling chamber inside the kettle body 1. That is, the steam pipe 14 is located slightly below the kettle opening above the kettle body. This is because after boiling water, the steam in the kettle needs to flow through the steam pipe 14. Therefore, the steam pipe 14 must be higher than the water surface. So the height of the steam pipe 14 cannot be too low. For example, a maximum water level limit mark is set on the kettle body.

[0055] As a preferred embodiment, the vertical arc-shaped portion 241 is provided with a retaining strip slot 242 at both ends; the pressing plate 21 is provided with side strips on both sides, and each side strip is provided with a buckle protrusion 212, which corresponds to the retaining strip slot 242 at both ends of the vertical arc-shaped portion 241.

[0056] In this invention, the kettle is also provided with a kettle stand 3; the kettle body 1 is plugged into the kettle stand 3 for power supply, the kettle body 1 is provided with a kettle handle 12 and a kettle spout 11, the kettle spout 11 is a curved, slender spout.

[0057] For ease of installation, an installation gap 215 is provided between the press button 211 and the vertical arc-shaped part 241. The front end of the cover plate 23 is also provided with a vertical insert strip 232. The vertical insert strip 232 is inserted into the installation gap 215. On the inner side wall of the first arc-shaped part 221, a semi-circular truncated cone 222 is provided inward at the center position. A semi-circular circular protrusion 243 is provided outward at the center of the vertical arc-shaped part 241. The truncated cone 222 and the circular protrusion 243 are arranged opposite to each other on both sides. The cylindrical interface 231 is located directly above the truncated cone 222 and the circular protrusion 243.

[0058] Working principle:

[0059] In this invention, when the button on the press plate is pressed, the kettle starts to boil water in the boiling chamber. As the water temperature slowly rises, water steam is gradually generated. The water steam enters from the opening of the steam pipe 14 and flows downward. Through the steam interface 135 set at the bottom of the kettle bottom cavity 133, the steam enters the steam chamber formed by the cylindrical interface 231, the vertical arc-shaped part 241 and the first arc-shaped part 221.

[0060] When the pressing button 211 is pressed down, the arc-shaped stop bar 24 moves downward through the snap-fit ​​protrusion 212, and the vertical arc-shaped part 241 also moves downward. A gap channel 26 is formed between the lower end of the vertical arc-shaped part 241 and the lower end of the first arc-shaped part 221. Therefore, the steam in the water heating chamber flows through the steam pipe 14, then through the cylindrical interface 231 to the steam chamber, and then through the gap channel 26 to the elastic temperature sensing plate 25. Therefore, the temperature sensing plate 25 can sense the temperature of the steam.

[0061] In this invention, the elastic temperature sensing sheet 25 is provided with a hollow portion, and an elastic strip 251 is provided in the hollow portion. When the pressing key at the front end of the pressing plate 21 is pressed down, the snap-fit ​​groove 213 at the rear end of the pressing plate 21 moves upward, causing one end of the rocker boss 272 to move upward, and the rear end of the rocker boss 272 moves downward. Therefore, the rocker protrusion 271 at the rear end of the rocker boss 272 presses down on the elastic strip 251 on the elastic temperature sensing sheet 25, causing the elastic strip 251 to deform downward, and maintaining the downward deformation state under the high temperature of steam.

[0062] When the water boils, the kettle stops heating, so the water in the kettle will no longer continue to boil and produce high-temperature steam. As a result, the amount of steam entering the steam pipe 14 will decrease rapidly to a very small amount, or even none. Therefore, only a very small amount, or even no high-temperature steam flows to the elastic temperature sensor 25, which will cool down rapidly. The deformed elastic strip 251 will then quickly rebound upwards and reset. This will drive the rocker protrusion 271 to move upwards, and the side opposite to the rocker protrusion 271 will move downwards, causing the latching groove 213 at the rear end of the pressing plate 21 to move downwards. Therefore, the button at the front end of the pressing plate 21 will rebound upwards and reset.

[0063] In this invention, the elastic temperature-sensing sheet 25 is made of metal. Due to thermal expansion and contraction, it maintains its deformed state under the action of high-temperature water vapor. When heating stops, the water in the kettle quickly stops producing a large amount of water vapor. When no high-temperature water vapor flows to the elastic temperature-sensing sheet, it cools down quickly, causing it to spring back and reset. This drives the button to quickly rebound and reset, allowing for the next water boiling operation. This solves the problem of traditional kettles where a sensor is placed inside the kettle to sense the water temperature, but the water temperature drops very slowly, making the button reset very slowly and unable to quickly resume water boiling.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
