DETAILED DESCRIPTION

[0032] 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.

[0033] For the anti-dumping and leaking lid switch structure, please refer to Figure 1-8 As shown, it comprises: a kettle cover body 100 , in which a pull rod assembly 200 and a lid lock assembly 300 are assembled.

[0034] like Figure 4 As shown, the kettle lid body 100 is installed at the kettle mouth 01 on the top of the kettle body 00, and the lid lock assembly 300 is used to lock or unlock the kettle lid body 100 and the kettle body 00. When locked, the kettle lid body 100 and the kettle body 00 are limited, and the kettle lid body 100 will not fall from the kettle body 00 when the entire kettle is tilted, preventing water from rushing out of the kettle mouth 01 and scalding the user; when unlocked, the kettle lid body 100 can be lifted up and taken out of the kettle body 00, making it convenient to replenish water or clean the kettle cavity 02 of the kettle body 00; the pull rod assembly 200 drives the lid lock assembly 300 to move, so that the kettle lid body 100 and the kettle body 00 are switched between a locked state and an unlocked state.

[0035] Specifically, the pull rod assembly 200 includes a button 210, a pull rod 220, and a pull rod spring 230. The pull rod 220 is provided with a first inclined guide surface 221. The button 210 is connected to the pull rod 220 and is used to trigger the movement of the pull rod 220. The pull rod spring 230 provides elastic force to reset the pull rod 220 after movement.

[0036] like Figure 2 As shown, the button 210 is located at the top of the pull rod 220, and the pull rod spring 230 is located at the bottom of the pull rod 220. The button 210, the pull rod 220 and the pull rod spring 230 can be coaxially installed vertically, as shown in FIG. Figure 3As shown, when in use, the button 210 is pressed downward, pushing the rod 220 downward, and the rod spring 230 is compressed; the force applied to the button 210 is released, and the rod 220 moves upward and resets under the elastic force of the rod spring 230, and the button 210 moves upward and resets under the push of the rod 220, and resets to Figure 2 Status shown.

[0037] The cover lock assembly 300 includes: a cover lock 310 and a cover lock spring 320 . The cover lock 310 is provided with a second inclined guide surface 311 and a lock tongue 312 .

[0038] like Figure 1-3 As shown, the lid lock assembly 300 is assembled in the pot lid body 100 and is located on the circumferential side of the pull rod 220. The side of the pot lid body 100 is provided with a through hole 101 for the lock tongue 312 to extend out; the lid lock spring 320 provides elastic force for the second inclined guide surface 311 to be close to the first inclined guide surface 221, and the lid lock 310 generates radial movement with the axial movement of the pull rod 220, controlling the inward or outward movement of the lock tongue 312.

[0039] Figure 2 In the embodiment, the cover lock assembly 300 is in a locked state, and the lock tongue 312 extends out of the through hole 101; Figure 4-5 As shown, after the pot lid body 100 is installed on the pot body 00, the locking tongue 312 extends out of the through hole 101, and the locking tongue 312 conflicts with the limiting portion at the pot mouth 01 in the vertical direction, so that the pot lid body 100 and the pot body 00 are limited in position, and the pot lid body 100 cannot be taken out upwards;

[0040] Figure 3 In the embodiment, the lid lock assembly 400 is in the unlocked state, and the lock tongue 312 is received in the lid body 100; Figure 6-7 As shown, after the pot lid body 100 is installed on the pot body 00, the locking tongue 312 is retracted into the pot lid body 100, and the locking tongue 312 no longer conflicts with the limiting part at the pot mouth 01 in the vertical direction. The pot lid body 100 and the pot body 00 are no longer limited, and the user can apply force to remove the pot lid body 100 upwards.

[0041] Continue as Figure 2 As shown, when the cover lock assembly 300 is in the locked state, the second inclined guide surface 311 is close to the first inclined guide surface 221 and is close to the lower end of the pull rod 220; the user presses the button 210 to push the pull rod 220 downward, as shown in FIG. Figure 3As shown, the horizontal height of the lid lock assembly 300 in the pot lid body 100 is unchanged, and when the pull rod 220 moves downward, since the first inclined guide surface 221 is tilted and gradually approaches the axis of the pull rod 220 from bottom to top, under the elastic force of the lid lock spring 320, the lid lock assembly 300 moves radially inward, that is, moves close to the axis of the pull rod 220, and finally the lock tongue 312 is collected in the pot lid body 100; and when the pull rod 220 moves upward, the lid lock assembly 300 is pushed radially outward by the first inclined guide surface 221, and the lid lock spring 320 is compressed.

[0042] Further, if Figure 5 As shown, the inner edge of the mouth 01 of the kettle body 00 forms a limiting portion, which is a bent edge 011. The bent edge 011 is designed with a circle. After the kettle lid body 100 is installed on the kettle body 00, it can ensure that the locking tongue 312 and the bent edge 011 interfere or conflict with each other in the vertical direction.

[0043] In one embodiment, a positioning guide is provided in the lid body 100 to guide the lid lock 310 to move radially;

[0044] Specifically, if Figure 1 and Figure 2 As shown, when the lid lock assembly 300 moves radially, the lock tongue 312 needs to align with the through-hole 101 and pass through the through-hole 101 smoothly. Therefore, a positioning guide structure is required to be provided in the lid body 100 to limit the movement trajectory of the lid lock 310. Figure 1 In the embodiment, the lower surface of the upper cover 110 of the lid body 100 is provided with a plurality of ribs 111, which define the positioning guide portion. The lid lock 310 is restricted in the positioning guide portion and can only move radially inward or outward.

[0045] Alternatively, the positioning guide portion may be designed in the form of a positioning groove, and the cover lock 310 is installed in the positioning groove and can move radially inward or outward in the positioning groove;

[0046] Alternatively, the positioning guide portion can be designed in the form of a guide rib, and a strip groove is designed on the cover lock 310, and the guide rib is stuck in the strip groove, limiting the cover lock 310 to only move radially inward or outward.

[0047] In one embodiment, the lid lock 310 is provided with a groove body 313 in which a lid lock spring 320 is assembled. The lid lock spring 320 is horizontally assembled in the groove body 313. One end of the lid lock spring 320 is supported on the inner wall of the groove body 313, and the other end is supported on an inner wall surface of the pot lid body 100. After the lid lock 310 moves radially outward, the lid lock spring 320 is in a compressed state.

[0048] In one embodiment, a positioning column 102 is provided in the lid body 100, and a pull rod spring 230 is sleeved on the positioning column 102 and acts on the pull rod 220, and the pull rod spring 230 provides elastic force for axial reset of the pull rod 220;

[0049] Furthermore, the lower end of the pull rod 220 is arranged in an umbrella shape and forms the first inclined guide surface 221; the pull rod 220 is arranged hollow, and the positioning column 102 can be inserted into the hollow part of the pull rod 220;

[0050] Specifically, if Figure 2 As shown, the positioning column 102 is integrally formed on the inner wall of the pot cover body 100, the pull rod spring 230 is sleeved outside the positioning column 102 and the upper end of the pull rod spring 230 is supported on the pull rod 220 to provide a reset force for the pull rod 220 to move upward;

[0051] The positioning post 102 is inserted into the hollow of the pull rod 220 to guide the pull rod 220 to move up and down in a straight line; the lower end of the pull rod 220 is arranged in an umbrella shape, and the entire umbrella surface constitutes a first inclined guide surface 221, ensuring that the second inclined guide surface 311 of the cover lock 310 can closely contact the first inclined guide surface 221;

[0052] In addition, multiple groups of lid lock assemblies 300 are arranged in the pot lid body 100, and the multiple groups of lid lock assemblies 300 are distributed around the circumference of the pull rod 220. The umbrella surface constitutes a first inclined guide surface 221, which can ensure that the second inclined guide surfaces 311 of the multiple groups of lid lock assemblies 300 can all be close to the first inclined guide surface 221.

[0053] Figure 1 In this embodiment, the lid lock assembly 300 is provided with two groups, and the locking between the lid body 100 and the kettle body 00 is more reliable.

[0054] In one embodiment, the pot lid body 100 is provided with a handle portion 140, which is convenient for the user to apply force to lift the pot lid body 100; the handle portion 140 is hollow, and the button 210 is installed in the hollow position of the handle portion 140, and the button 210 is blocked on the upper end surface of the handle portion 140 to prevent foreign matter from entering the pot lid body 100; the button 210 is connected to the upper end of the pull rod 220, and the button 210 and the pull rod 220 can be fixed by a buckle or a screw; Figure 3 As shown, the upper width of the hollow portion of the handle portion 140 is greater than the lower width, so as to limit the downward movement distance of the button 210.

[0055] In one embodiment, the pot cover body 100 includes: an upper cover 110, a lower cover 120 and a sealing ring 130, wherein the sealing ring 130 is located between the upper cover 110 and the lower cover 120; a plurality of through holes 101 are provided on the circumference of the lower cover 120;

[0056] The lid body 100 adopts a split structure, which is convenient for the installation of the pull rod assembly 200 and the lid lock assembly 300; the sealing ring 130 seals the gap between the upper cover 110 and the lower cover 120; Figure 3 As shown, the sealing ring 130 is further provided with a sealing lip 131 , which is used to seal between the pot cover body 100 and the pot mouth 01 .

[0057] Furthermore, a locking tongue sealing ring 330 is sleeved on the locking tongue 312. When the lid lock 310 moves radially outward, the locking tongue 312 extends out from the through-hole 101.
