Description

Technical Field

[0001] The present invention belongs to the technical field of electrical appliance structures and relates to a kettle that can be quickly reset. Background Art

[0002] A kettle is a commonly used electrical appliance product at present. For many current kettles, such as push-button kettles, after the button is pressed down, the kettle starts to work and boil water. Traditional kettles are equipped with a temperature sensor inside the kettle to sense the water temperature. After the water temperature drops to a certain level, the button rebounds and resets. Since the temperature of boiling water drops slowly, it takes a long time for the water temperature to decrease. Therefore, it takes a long time for the button of the kettle to rebound and reset. As a result, it is impossible to boil water again immediately and cannot meet the demand, so it urgently needs to be improved. Summary of the Invention

The pressing component includes a pressing plate 21, and a pressing key 211 is provided at the front end of the pressing plate 21; the pressing key 211 is pressed downward or rebounds upward to reset; an opening is provided on the side of the kettle bottom plate 13, and the pressing key 211 extends outward from the opening for pressing.

[0044] The pressing component 2 is further provided with a mounting support seat 22, a cover plate 23 and an arc-shaped retaining strip 24; the arc-shaped retaining strip 24 is provided with a vertical arc portion 241 and a bottom baffle 242; a retaining strip bayonet 242 is provided at the end of the vertical arc portion 241.

[0045] A first arc portion 221 is provided at the front end of the mounting support seat 22, the arc-shaped retaining strip 24 is arranged at the front end of the first arc portion 221, and the vertical arc portion 241 and the first arc portion 221 are arranged in a fitting manner.

[0046] The cover plate 23 is provided with a cylindrical interface 231, and the cylindrical interface 231 is connected to the steam interface 135; the cover plate 23 is located above the vertical arc portion 241 and the first arc portion 221; and the cylindrical interface 231, the vertical arc portion 241 and the first arc portion 222 together form a steam cavity; an elastic temperature-sensitive sheet 25 is provided below the first arc portion 221.

[0047] The pressing plate 21 is further provided with a lateral strip, and a snap boss 212 and a snap groove 213 are provided on the lateral strip; the snap boss 212 is arranged in the retaining strip bayonet 242.

[0051] In the present invention, after the pressing key 211 is pressed downward, the arc-shaped retaining strip 24 is driven to move downward by the snap boss 212, the vertical arc portion 241 also moves downward, and a gap channel 26 is formed between the lower end of the vertical arc portion 241 and the lower end of the first arc portion 221; the steam in the water-boiling cavity flows through the steam pipe 14, then flows through the cylindrical interface 231 to the steam cavity, and then flows through the gap channel 26 to the elastic temperature-sensitive sheet 25.

[0052] After cooling, the elastic strip 251 automatically bounces back to its original position. After bouncing up, it pushes up the rocker bump 271 upwards, so that the rocker boss 272 moves downwards, pressing one side of the buckle groove 213 to move downwards, and making one side of the push button 211 bounce up and reset.

[0053] As a preferred solution, the height of the steam pipe 14 is slightly lower than the height of the water heating cavity in the kettle body 1, that is, the steam pipe 14 is located at a position slightly below the kettle mouth above the kettle body. Because after boiling water, the steam in the kettle needs to flow through the steam pipe 14, so the steam pipe 14 must be higher than the water surface, so the height of the steam pipe 14 cannot be too low. Exemplarily, a maximum water level limit mark is set on the kettle body.

[0054] As a preferred implementation, blocking strip buckles 242 are respectively provided at both ends of the vertical arc portion 241; lateral strips are provided on both sides of the pressing plate 21, and buckle bosses 212 are provided on each lateral strip, corresponding to the blocking strip buckles 242 at both ends of the vertical arc portion 241 respectively.

[0055] In the present invention, the kettle further includes a kettle base 3; the kettle body 1 is installed and powered on in a plug-in manner with the kettle base 3. A kettle handle 12 is provided on the kettle body 1, and a kettle spout 11 is also provided. The kettle spout 11 is a curved and slender spout.

[0056] For the convenience of installation, an installation gap 215 is provided between the push button 211 and the vertical arc portion 241. At the front end of the cover plate 23, a vertical insertion strip 232 is further provided; the vertical insertion strip 232 is inserted into the installation gap 215. On the inner side wall of the first arc portion 221, a semi-circular round platform 222 is inwardly provided at the middle position; a semi-circular round protrusion 243 is outwardly provided at the middle position of the vertical arc portion 241; the round platform 222 and the round protrusion 243 are arranged oppositely on both sides, and the cylindrical interface 231 is located directly above the round platform 222 and the round protrusion 243.

[0057] Working principle:

[0058] In the present invention, when the button on the pressing plate is pressed, the kettle starts to boil the water in the water heating cavity. As the water temperature slowly rises, water vapor is gradually generated. The water vapor enters from the pipe orifice of the steam pipe 14 and flows downwards, and enters the steam cavity jointly formed by the cylindrical interface 231, the vertical arc portion 241 and the first arc portion 222 through the steam interface 135 provided at the bottom of the bottom cavity 133 of the kettle body.

[0059] Because after the push button 211 is pressed downward, the arc-shaped retaining bar 24 is driven to move downward through the buckle boss 212, and the vertical arc-shaped portion 241 also moves downward, and a gap channel 26 is formed between the lower end of the vertical arc-shaped portion 241 and the lower end of the first arc-shaped portion 221; therefore, the steam in the water-boiling chamber passes through the steam pipe 14, then flows to the steam chamber through the cylindrical interface 231, and then flows to the elastic temperature-sensitive sheet 25 through the gap channel 26; therefore, the temperature-sensitive sheet 25 can sense the temperature of the steam.

[0060] In the present invention, a hollow portion is provided on the elastic temperature-sensing sheet 25, 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 downward, the snap groove 213 at the rear end of the pressing plate 21 moves upward, driving one end of the seesaw boss 272 to move upward, and the rear end of the seesaw boss 272 moves downward. Therefore, the rear end seesaw protrusion 271 of the seesaw boss 272 presses downward the elastic strip 251 on the elastic temperature-sensing sheet 25, so that the elastic strip 251 is deformed downward and maintains the downward deformation state under the high temperature of the steam.

[0061] When the water boils, the kettle stops heating the water, and the water in the kettle will not continue to boil and produce high-temperature steam. Therefore, the amount of steam entering the steam pipe 14 will rapidly decrease until it is a very small amount, or even no steam will enter. Therefore, only a very small amount, or even no high-temperature steam will flow to the elastic temperature-sensitive sheet 25, and the elastic temperature-sensitive sheet 25 will rapidly cool down, and the deformed elastic strip 251 will rapidly rebound upward and reset; it will drive the seesaw protrusion 271 to move upward, and the other side away from the seesaw protrusion 271 will move downward, driving the buckle groove 213 at the rear end of the pressing plate 21 to move downward, so the button at the front end of the pressing plate 21 will rebound upward and reset.

[0062] In the present invention, the elastic temperature-sensing piece 25 is made of a metal material. Due to thermal expansion and contraction, it maintains a deformed state under the action of high-temperature water vapor. When the heating of the water is stopped, the water in the kettle will quickly stop generating a large amount of water vapor. When there is no high-temperature water vapor flowing to the elastic temperature-sensing piece, it will quickly cool down, resulting in rebound and reset. Thus, the pressing key is driven to rebound and reset quickly, and the next water boiling operation can be performed quickly. This solves the problem that in the traditional kettle, a sensor is set in the kettle to sense the water temperature, and the water temperature drops very slowly, which makes the button reset very slowly and cannot quickly boil water again.

[0063] The above are only the preferred embodiments of the present invention and are 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
