Description

Technical Field

[0001] The utility model relates to the technical field of electric kettles, and more particularly to a spout sealing structure of an electric kettle. Background Art

[0002] Electric kettles on the market have a kettle body with a water spout. When the kettle body is tilted, the hot water in the kettle body is poured out through the spout. Sometimes, when the kettle body is tilted incorrectly or accidentally falls, the boiling hot water can easily flow out of the spout and scald the user, causing injury.

[0003] Therefore, in order to prevent the boiling hot water from scalding the user when the kettle body is accidentally tipped over, a sealing structure is provided corresponding to the spout in the electric kettle. The existing Chinese patent number: CN200920056201.8 discloses an electric kettle, which includes a kettle body and a kettle lid. A spout sealing device is installed at the spout water hole of the kettle body. The spout sealing cover is connected to one end of a driving device that controls its opening, and the other end of the driving device is connected to a pouring switch; when the user needs to pour water, he presses the pouring control switch installed on the handle, and the pouring control switch pushes the push rod to move, and the push rod drives the connecting rod installed on the kettle lid to move, and the connecting rod drives the spout sealing device installed at the spout water hole to open, so that water flows out from the spout water hole.

[0004] The connecting rod of this prior art is installed on the kettle lid, which is suitable for a kettle structure with the spout arranged close to the kettle mouth. However, for some kettles with gooseneck spouts, the water outlet is arranged close to the bottom of the kettle, and the above-mentioned prior art structure is not applicable; and the connecting rod and other structures need to be extended into the cavity, which is difficult to clean. At the same time, a complex sealing structure needs to be provided on the kettle lid to prevent water from entering the kettle lid.

DETAILED DESCRIPTION

[0035] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0036] For the sealing structure of the spout of the electric kettle, please refer to Figure 1-7 As shown, the electric kettle has a kettle body 100. The electric kettle can be an integrated structure electric kettle or a split structure electric kettle. For the split structure electric kettle, a base is also required at the bottom of the kettle body, and the kettle body and the base are connected by a coupler. Figure 1 The electric kettle in the figure is an integrated structure electric kettle, which can be used by powering on. The interior of the kettle body 100 is formed with a kettle cavity 01 for storing water, and a water outlet 02 is provided in communication with the kettle cavity 01.

[0037] A rotating mechanism 200 is provided in the pot cavity 01 corresponding to the water outlet 02. The rotating mechanism 200 includes at least a water blocking member 210 acting on the water outlet 02 and a first magnetic member 220 connected to the water blocking member 210.

[0038] The kettle body 100 is provided with a locking mechanism 300, which includes: a trigger switch 310 and a second magnetic member 320; the second magnetic member 320 is connected to the trigger switch 310;

[0039] The first magnetic member 220 and the second magnetic member 320 are close to each other and magnetically attracted to each other;

[0040] When the second magnetic member 320 moves following the trigger switch 310, the magnetic attraction force drives the first magnetic member 220 and the water retaining member 210 to move accordingly, thereby controlling the opening and closing of the water outlet 02;

[0041] Specifically, Figure 1-3As shown, when the locking mechanism 300 is not subjected to external force (i.e., the user does not activate the trigger switch 310), the first magnetic member 220 and the second magnetic member 320 are close to each other, and the water blocking member 210 blocks the water outlet 02. At this time, the kettle body 100 is tilted, and the water in the kettle cavity 01 cannot be discharged through the water outlet 02.

[0042] like Figure 4-6 As shown, force is applied to the locking mechanism 300, pushing the trigger switch 310 to move, and the second magnetic component 320 follows the movement. Under the action of the magnetic force, the first magnetic component 220 follows the second magnetic component 320 to move, and then drives the water retaining component 210 to move, and the water outlet 02 is opened. At this time, the kettle body 100 is tilted, and the water in the kettle cavity 01 can be sent out through the water outlet 02.

[0043] The rotating mechanism 200 is installed in the pot cavity 01, and the locking mechanism 300 can be installed in the pot cavity 01 or outside the pot cavity 01. Preferably, the locking mechanism 300 is installed outside the pot cavity 01 to reduce the space occupied by the pot cavity 01 and reduce the waterproof work done for the locking mechanism 300.

[0044] In one embodiment, Figure 2 As shown, the kettle body 100 is provided with a bottom cavity 03 below the kettle cavity 01, the trigger switch 310 and the second magnetic attraction member 320 are assembled in the bottom cavity 03, and the trigger switch 310 is partially protruded / exposed outside the kettle body 100;

[0045] Specifically, a shell 130 is provided at the bottom of the kettle body 100, and a bottom cavity 03 is formed between the shell 130 and the outer bottom wall of the kettle cavity 01, and the heating element can be installed in the bottom cavity 03;

[0046] The trigger switch 310 is a push-type trigger structure, that is, the movement of the trigger switch 310 between the closed position and the triggered position is linear. Therefore, a limit groove and other structures can be defined in the bottom cavity 03. The trigger switch 310 is installed in the limit groove and can move linearly to switch between the closed position and the triggered position.

[0047] like Figure 1 and Figure 3 As shown, when the trigger switch 310 is in the closed position, the front end of the trigger switch 310 protrudes outside the housing;

[0048] like Figure 4 and Figure 6 As shown, when the trigger switch 310 is in the trigger position, the trigger switch 310 as a whole is relative to Figure 1 and Figure 3 Move to the right in terms of position.

[0049] Furthermore, if Figure 3As shown, when the trigger switch 310 is in the closed position, the second magnetic member 320 and the first magnetic member 310 are located in corresponding positions up and down.

[0050] like Figure 1 As shown, in this embodiment, the kettle body 100 is roughly barrel-shaped, and the inner wall surface of the kettle cavity 01 is arc-shaped, so the trigger switch 310 switches between the closed position and the trigger position by radial movement, and the trigger switch 310 is a push-type switch.

[0051] Continue as Figure 3 As shown, the second magnetic member 320 is installed on the upper side of the trigger switch 310, and a position for fixing and assembling the second magnetic member 320 is provided on the trigger switch 310.

[0052] In one embodiment, the locking mechanism 300 further includes a return spring 330 , one end of which is restrained within the bottom cavity 03 and the other end of which is restrained within the trigger switch 310 . The return spring 330 provides a return force after the trigger switch 310 moves. Specifically, the return spring 330 provides an elastic force to return the trigger switch 310 from the triggered position to the closed position.

[0053] The trigger switch 310 can be a step-by-step push switch, such as Figure 3 As shown, when the trigger switch 310 is in the closed position, the trigger switch 310 is pressed for the first time, and the trigger switch 310 moves to the trigger position, that is, Figure 6 The trigger switch 310 is held in the position shown. Figure 6 In the trigger position shown, the water blocking member 210 moves accordingly, the water outlet 02 opens, and the user can tilt to pour water;

[0054] After pouring the water, the trigger switch 310 is pressed for the second time, and the trigger switch 310 is reset to the closed position under the elastic force of the reset spring 330. Figure 3 In the position shown, the water blocking member 210 moves accordingly and the water outlet 02 is closed.

[0055] Alternatively, the trigger switch 310 may refer to the locking principle of an alternating switch, similar to the button structure of a ballpoint pen.

[0056] In one embodiment, the water retaining member 210 includes: a water retaining plate 211 and a sealing silicone 212. The sealing silicone 212 is installed on the side of the water retaining plate 211. When the water retaining member 210 acts on the water outlet 02, the sealing silicone 212 blocks the water outlet 02.

[0057] Furthermore, the upper end of the water baffle 211 is rotatably mounted in the pot cavity 01 via a rotating shaft 213, and the first magnetic member 220 is mounted on the lower end of the water baffle 211;

[0058] Specifically, if Figure 3 As shown, a position for assembling the first magnetic member 220 is provided at the lower end of the water baffle 211;

[0059] like Figure 2 As shown, the sealing silica gel 212 is provided on the left side of the water retaining plate 211. When the water retaining member 210 closes the water outlet 02, the sealing silica gel 212 contacts the inner wall surface of the water outlet 02.

[0060] Optionally, the sealing silica gel 212 may also adopt a wrapping structure, and entirely wrap around the surface of the water baffle 211 .

[0061] like Figure 2 and Figure 5 As shown, when the force is applied to press the trigger switch 310 for the first time, the trigger switch 310 changes from Figure 2 Move right to Figure 5 In the orientation shown, at the same time, the water blocking member 210 rotates counterclockwise to leave the water outlet 02;

[0062] When the trigger switch 310 is pressed for the second time, the trigger switch 310 is Figure 5 Move left to Figure 2 As shown in the orientation, at the same time, the water blocking member 210 rotates clockwise to close the water outlet 02.

[0063] In one embodiment, the rotating mechanism 200 further includes: a cover 230, which is assembled in the pot cavity 01 and covers the water outlet 02; Figure 7 As shown, the cover body 230 is provided with a water outlet hole 231; the water retaining member 210 is located within the covering range of the cover body 230, and there is space for the water retaining member 210 to rotate between the cover body 230 and the inner wall of the pot cavity 01; the water in the pot cavity 01 can enter the covering space of the cover body 230 through the water outlet hole 231.

[0064] Optionally, the water retaining member 210 may also be rotatably connected to the cover body 230 via a rotating shaft 213 .

[0065] To a certain extent, when tea is boiled directly in an electric kettle, the cover 230 can also play a role in isolating residues.

[0066] In one embodiment, the first magnetic member 220 and the second magnetic member 320 are both magnets, and are magnetically attracted to each other.

[0067] Alternatively, one of the first magnetic member 220 and the second magnetic member 320 is a magnet, and the other is a metal block that can be attracted by the magnet;

[0068] like Figure 3As shown, preferably, the first magnetic member 220 and the second magnetic member 320 are both magnets, and the upper end of the first magnetic member 220 is the S pole and the lower end is the N pole; the upper end of the second magnetic member 320 is the S pole and the lower end is the N pole. The first magnetic member 220 and the second magnetic member 320 are magnetically attracted to each other, and the magnetic attraction force is stronger than that of one of them being designed as a metal block.

[0069] In one embodiment, Figure 2 As shown, the kettle body 100 is provided with a gooseneck mouth 110 and a handle 120, and the gooseneck mouth 110 is connected to the water outlet 02;

[0070] When using, Figure 8 As shown, when the trigger switch 310 is in the closed position, the water blocking member 210 closes the water outlet 02. Even if the kettle body 100 is tilted, the water in the kettle cavity 01 cannot be sent out through the water outlet 02 and the gooseneck mouth 110.

[0071] like Figure 9 As shown, when the trigger switch 310 is in the trigger position, the water blocking member 210 leaves the water outlet 02 and the water outlet 02 is opened. At this time, the kettle body 100 is tilted, and the water in the kettle cavity 01 is also sent out through the water outlet 02 and the gooseneck mouth 110.

[0072] like Figure 10 As shown, when the electric kettle accidentally falls to the ground, the side of the kettle body 100 contacts the ground, and at the same time the gooseneck mouth 110 tilts to the lower left, and the handle 120 tilts to the upper right, the water retaining member 210 closes the water outlet 02, and the water in the kettle cavity 01 cannot be sent out through the gooseneck mouth 110 through the water outlet 02, thereby playing a leak-proof role.

[0073] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
