Description

Technical Field

[0001] This utility model belongs to the field of water cup technology and relates to a water cup that can quickly boil water. Background Technology

[0002] There are many instant water bottles on the market. The lid and body of a regular water bottle are connected by threads for opening and closing. Compared to regular water bottles, instant water bottles are more convenient and faster to open and close.

[0003] The existing instant water cup opening and closing structure generally includes several locking blocks set on the cup lid by rotation, locking slots opened on the cup body, and a spring set inside the cup lid to push each locking block to unfold outward and insert into the locking slot for locking. A button is set on the top of the cup lid. After pressing the button, the button drives each locking block to rotate inward and disengage from the locking slot to unlock, thereby realizing the opening of the lid.

[0004] However, this type of instant water cup has the following disadvantages:

[0005] 1. Since each locking block is independently rotated inside the cup lid, the button works with each locking block through multiple transmission components to drive each locking block to rotate. Due to the multiple transmission steps between the button and the transmission components, and between the transmission components and the locking blocks, it is easy for the locking blocks to not be properly driven, thus affecting the opening or closing of the lid.

[0006] 2. When closing the lid, you need to press down on the lid. The cup body will squeeze the locking blocks, causing them to overcome the spring force and enter the locking slots along the cup opening. This process requires the user to press the lid firmly. When the spring force is too great, the pressing force also needs to be increased, making the lid closing process more difficult. Summary of the Invention

[0007] The purpose of this invention is to address the aforementioned problems of existing quick-boil water cups by proposing a water cup in which the button directly drives the displacement of the chuck and there are no extra transmission components between the button and the chuck.

[0008] The objective of this utility model can be achieved through the following technical solutions:

[0009] A quick-boiling water cup includes a lid and a cup body. The lid comprises a lid body, a button movably mounted on the top of the lid body, and locking blocks movably mounted within the lid body. Several locking blocks are spaced apart circumferentially along the button and can move back and forth radially along the lid body. The lid body has openings corresponding to the positions of each locking block. A return spring within the lid body drives the locking blocks to move outwards, causing each locking block to extend beyond the opening and form a locked state. A guide structure is provided between the button and the locking blocks; pressing the button pushes each locking block inwards through the guide structure, causing each locking block to retract into the opening and form an unlocked state.

[0010] The cup lid is also equipped with a limiting structure to limit the position of each locking block when it is unlocked. The lid is also equipped with a reset spring to drive the button to lift and reset so that the button is separated from each locking block.

[0011] In the aforementioned instant hot water cup, the limiting structure includes a limiting ring that is movably disposed within the lid body and a limiting hole formed on the locking block. Several limiting blocks are fixed on the limiting ring. In the unlocked state, the position of the upper limiting hole of each locking block corresponds one-to-one with the position of each limiting block. The lid body is also provided with a reset spring three for driving the limiting ring to move downward, so that the limiting block is inserted downward into the corresponding limiting hole to form a limiting and locking state.

[0012] In the aforementioned instant hot water cup, the top of the cup body is provided with a cup mouth, and a retaining ring is fixedly provided on the inner wall of the cup body. When the lid is closed, each limiting block can be blocked by the retaining ring. The retaining ring pushes the limiting block out of the limiting hole to form a limiting unlocked state. A locking groove is provided on the inner wall of the cup mouth. After the lid is closed, a return spring drives the locking block to move outward so that each locking block extends out of the opening and inserts into the locking groove to lock the cup lid and the cup body.

[0013] In the aforementioned instant hot water cup, the guiding structure includes a guide block fixed on the locking block, a guide groove opened on the button and corresponding to the position of each guide block, a guide hole opened at the bottom of the button, the guide hole being a frustum-shaped structure with a larger bottom and a smaller top, the guide groove being opened on the outer wall of the guide hole and extending along the generatrix of the frustum, and each guide block being embedded in the corresponding guide groove.

[0014] In the aforementioned instant hot water cup, the button is fixed with several vertical anti-rotation blocks, and the cover is provided with several limiting grooves that correspond one-to-one with the positions of each anti-rotation block. The anti-rotation blocks are embedded in the corresponding limiting grooves and slide up and down along the limiting grooves to limit the rotation of the button relative to the cover.

[0015] In the aforementioned instant hot water cup, the lid has several guide grooves extending radially thereon, and each locking block is slidably disposed in the corresponding guide groove; a recessed hole is also provided in the guide groove, a reset spring is disposed in the recessed hole, an extension piece is fixedly disposed at the bottom of the locking block, the extension piece is inserted into the recessed hole, and the two ends of the reset spring are pressed against the inner wall of the recessed hole and the extension piece, respectively.

[0016] In the aforementioned instant hot water cup, the lid includes a top cover, an upper cover, and a lower cover arranged sequentially from top to bottom. The upper cover is fastened and fixed to the top cover, and the lower cover is fastened and fixed to the upper cover.

[0017] In the aforementioned instant hot water cup, the lid also includes a pressure cap, which is located between the top cover and the bottom cover. A guide groove is formed on the bottom cover, with an opening at the top. After the locking block is placed into the guide groove, the pressure cap closes at the opening of the guide groove to prevent the locking block from coming out of the guide groove.

[0018] In the aforementioned instant hot water cup, a plurality of guide posts are fixed on the limiting ring, and guide holes corresponding to the positions of each guide post are opened on the upper cover. The guide posts are inserted into the corresponding guide holes, and when the limiting ring moves up and down relative to the cover, the guide posts move up and down synchronously along the guide holes.

[0019] In the aforementioned instant hot water cup, a piston rod is movably mounted on the lower cover, and a sealing plug is fixedly mounted at the bottom of the piston rod. A piston hole communicating with the interior of the cover is opened at the bottom of the lower cover. Two return springs are sleeved on the piston rod and push the piston rod to lift it up, so that the top surface of the piston rod abuts against the button and the sealing plug is embedded in the piston hole to form a seal.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The lock block and the button are guided and limited by the guide groove and the guide block. After the button is pressed, the button can push the lock block to move inward to unlock. After the button is released, it will automatically reset by the spring. There are no extra transmission parts, the structure is simple and the transmission is efficient.

The lid includes a cover body, a button 1 movably mounted on the top of the lid body, and locking blocks 2 movably mounted inside the lid body. Several locking blocks 2 are spaced apart circumferentially along the button 1 and can move back and forth radially along the lid body. The lid body has openings 3 corresponding to the positions of each locking block 2. A return spring 4 is provided inside the lid body to drive the locking blocks 2 to move outward, so that each locking block 2 extends out of the opening 3 to form a locked state. A guide structure is provided between the button 1 and the locking blocks 2. When the button 1 is pressed, the button 1 can push each locking block 2 inward through the guide structure, so that each locking block 2 retracts into the opening 3 to form an unlocked state.

[0034] The cup lid also includes a limiting structure to limit the position of each locking block 2 when unlocked. A second return spring 5 is also provided inside the lid to drive the button 1 to rise and reset, thus separating the button 1 from each locking block 2. The limiting structure includes a limiting ring 6 that moves vertically within the lid and limiting holes 7 formed on the locking blocks 2. Several limiting blocks 8 are fixed on the limiting ring 6. When unlocked, the position of each locking block 2 above the limiting hole 7 corresponds vertically to the position of each limiting block 8. A third return spring 9 is also provided inside the lid to drive the limiting ring 6 downwards, causing the limiting blocks 8 to insert downwards into the corresponding limiting holes 7 to form a limiting and locking state.

[0035] The cup body has a cup mouth at the top and a retaining ring fixed on the inner wall of the cup body. When the lid is closed, each limiting block 8 can be blocked by the retaining ring. The retaining ring pushes the limiting block 8 out of the limiting hole 7 to form a limiting unlocked state. A locking slot is opened on the inner wall of the cup mouth. After the lid is closed, the return spring 4 drives the locking block 2 to move outward so that each locking block 2 extends out of the opening 3 and is inserted into the locking slot to lock the cup lid and the cup body.

[0036] like Figure 6 As shown, the guiding structure includes guide blocks 10 fixed on the locking block 2, and guide grooves 11 on the button 1 corresponding to the positions of each guide block 10. A guide hole is formed at the bottom of the button 1, which is a frustum-shaped structure with a larger bottom and a smaller top. The guide grooves 11 are formed on the outer wall of the guide hole and extend along the generatrix of the frustum. Each guide block 10 is embedded in its corresponding guide groove 11. Several vertical anti-rotation blocks 12 are fixed on the button 1, and several limiting grooves 13 corresponding to the positions of each anti-rotation block 12 are formed on the cover. The anti-rotation blocks 12 are embedded in their corresponding limiting grooves 13 and slide up and down along the limiting grooves 13 to restrict the rotation of the button 1 relative to the cover.

[0037] like Figure 7 As shown, the cover has several guide grooves 14 extending radially therein, and each locking block 2 is slidably disposed in the corresponding guide groove 14; a recessed hole 16 is also provided in the guide groove 14, and a return spring 4 is disposed in the recessed hole 16. An extension piece 15 is fixedly provided at the bottom of the locking block 2, and the extension piece 15 is inserted into the recessed hole 16. The two ends of the return spring 4 are pressed against the inner wall of the recessed hole 16 and the extension piece 15, respectively.

[0038] like Figure 4 and Figure 5 As shown, the cover includes a top cover 17, an upper cover 18, and a lower cover 19 arranged sequentially from top to bottom. The upper cover 18 is fastened and fixed to the top cover 17, and the lower cover 19 is fastened and fixed to the upper cover 18. The cover also includes a pressure cap 20, which is located between the top cover 17 and the lower cover 19. A guide groove 14 is formed on the lower cover 19, with an opening 3 at the top of the guide groove 14. After the locking block 2 is placed into the guide groove 14, the pressure cap 20 closes at the opening 3 of the guide groove 14 to prevent the locking block 2 from coming out of the guide groove 14. A plurality of guide posts 21 are fixed on the limiting ring 6. The upper cover 18 has guide holes 22 that correspond one-to-one with the positions of each guide post 21.

[0040] The working principle of this utility model is as follows:

[0041] like Figure 3 As shown, when opening the lid, press button 1. Button 1 pushes each locking block 2 to move inward, so that each locking block 2 is disengaged from the locking slot of the cup body to form an unlocked state. Lift the cup lid upward, and the reset spring 3 9 drives the limit ring 6 to move downward. The limit block 8 is inserted downward into the limit hole 7, so that the locking block 2 is kept in the unlocked state, and the cup lid can be easily removed.

[0042] like Figure 2 As shown, when closing the lid, the lid is pressed into the cup body, and the limiting block 8 is pushed up through the cup mouth to make the limiting block 8 move upward out of the limiting hole 7. The reset spring 4 drives the locking block 2 to move outward, so that each locking block 2 extends out of the opening 3 and is inserted into the locking slot to lock the lid and the cup body.
