Description

Technical Field

[0001] This utility model relates to the field of thermos cup technology, and in particular to a thermos cup. Background Technology

[0002] The core technology of thermos cups, which are widely used in modern life, lies in their physical structure design to block heat transfer and achieve good heat preservation.

[0003] Traditional thermos cups typically seal their lids and bodies by screwing them together. However, users often struggle to control the force when tightening the lid. Overtightening the threads can increase friction or cause misalignment, making the lid difficult to open. Furthermore, when the user's hands are wet or sweaty, the friction between the user's hand and the lid decreases significantly, leading to slippage and making it difficult to open, thus affecting ease of use.

[0004] Therefore, a thermos cup that is easy for users to open or close was proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings by providing a thermos cup that allows users to easily open or close it, thus improving ease of use.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a thermos cup, including a cup body, the top of which is detachably provided with a cup lid;

[0007] A sealing component, including a sealing block, is coaxially disposed below the cup lid and forms surface contact with the inner wall of the cup.

[0008] It also includes a sealing ring, which is coaxially disposed on the inner wall of the cup and located below the sealing block;

[0009] A connecting component is disposed inside the cup lid, which is used to drive the sealing block to contact the sealing ring to seal the inner cavity of the cup, and at the same time connect the cup body to the cup lid.

[0010] Furthermore, the connecting component includes a trigger assembly disposed inside the cup lid, used to drive the sealing block to move vertically up and down;

[0011] An abutment component is disposed inside the cup lid and connected to a trigger component, used to constrain the movement of the sealing block via the trigger component;

[0012] A locking component is disposed inside the cup lid, one end of which is detachably connected to the abutment component, and the other end is detachably connected to the cup body, for controlling the connection and separation of the cup body and the cup lid.

[0013] Furthermore, a first chamber is formed in the cup lid;

[0014] The triggering components include;

[0015] The pressure rod is axially slidably inserted through the center of the cup lid, with its top end extending to the outside of the cup lid and its bottom end penetrating the first chamber and connecting to the sealing block.

[0016] The sleeve is vertically inserted into the first cavity and forms an axial sliding fit with the outer wall of the pressure rod;

[0017] The first elastic unit is disposed inside the sleeve and connected to the pressure rod and the cup lid respectively, and is used to apply a vertically upward pulling force to the pressure rod.

[0018] Furthermore, two snap-fit ​​grooves are symmetrically formed on the top circumferential surface of the inner wall of the cup, and a sliding groove corresponding to each snap-fit ​​groove is formed at the bottom of the first chamber;

[0019] The locking assembly includes two opposing push rods that are radially slidably inserted into the side wall of the cup lid, with the protruding end of each push rod extending to the outer wall of the cup lid;

[0020] The bottom of the cup lid is also symmetrically provided with two locking blocks that correspond to each of the locking slots;

[0021] Each of the top rods is further provided with a connecting rod between it and the corresponding locking block, and each of the connecting rods forms a sliding fit with the corresponding sliding groove.

[0022] Furthermore, the sleeve is provided with two symmetrical openings;

[0023] The abutting assembly includes two abutting blocks that are slidably disposed in the pressure rod and correspond one-to-one with each of the openings;

[0024] A second elastic unit is also provided between each of the abutting blocks and the pressure rod, for applying a thrust to the corresponding abutting block in a direction away from the axis of the cup body.

[0025] Furthermore, a third elastic unit is provided between each of the push rods and the cup lid, for applying an elastic force to the corresponding push rod in the direction close to the axis of the cup body.

[0026] Furthermore, two second chambers are symmetrically formed in the cup body, and each chamber is provided with a guide groove, and each guide groove surrounds the protruding end of the corresponding top rod.

[0027] The cup lid is also provided with a limiting component, including a pressure cap that is rotatably and slidably inserted into each of the second chambers, and each pressure cap is rotatably connected to the protruding end of the corresponding top rod;

[0028] Each of the glands has a limiting block at its insertion end that mates with the guide groove.

[0029] The beneficial effects of this utility model are reflected in:

[0030] In this invention, when the cup needs to be closed, the user presses down the pressure rod, causing the sealing block to move downwards and contact the sealing ring. The sealing block is compressed to seal the inner cavity of the cup. At this time, the abutment component engages with the sleeve, thereby restraining the movement of the pressure rod. Simultaneously, the abutment component connects the locking component to the cup body, thus connecting the cup lid to the cup body. When the cup needs to be opened, the user presses the locking component to separate it from the cup body. There is no need for the user to exert force to turn the cup lid, saving effort and ensuring ease of use. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0038] Please see Figure 1-4The present invention discloses a thermos cup, including a cup body 1, the top of which is detachably provided with a cup lid 2, and a first chamber 21 is provided in the cup lid 2;

[0039] The sealing component 3 includes a sealing block 31, which is coaxially disposed below the cup lid 2 and forms a surface contact with the inner wall of the cup body 1;

[0040] It also includes a sealing ring 32, which is coaxially disposed on the inner wall of the cup body 1 and located below the sealing block 31, for cooperating with the sealing block 31 to seal the inner cavity of the cup body 1;

[0041] The connecting component 4 includes a pressure rod 41, which is axially slidably inserted through the center of the cup lid 2. Its top end extends out of the cup lid 2, and its bottom end passes through the first chamber 21 and is connected to the sealing block 31. The pressure rod 41 is used to drive the sealing block 31 to move vertically.

[0042] Sleeve 42 is vertically inserted into the first chamber 21 and forms an axial sliding fit with the outer wall of pressure rod 41;

[0043] The first elastic unit 43 is disposed inside the sleeve 42 and connected to the pressure rod 41 and the cup lid 2 respectively, and is used to apply a vertically upward pulling force to the pressure rod 41;

[0044] The abutment component 44 is disposed inside the pressure rod 41, and one end of it is detachably snapped onto the sleeve 42 to constrain the movement of the pressure rod 41;

[0045] The locking component 45 is movably disposed inside the cup lid 2, with one end detachably connected to the abutment component 44 and the other end detachably connected to the cup body 1.

[0046] In practice, when it is necessary to close the cup body 1, the user places the cup lid 2 at the opening 421 of the cup body 1 and then presses down the pressure cap 61. At this time, the first elastic unit 43 is stretched, and the pressure cap 61 drives the sealing block 31 to move downward so that it contacts the sealing ring 32. The sealing block 31 is squeezed and deformed, thereby filling the gap between the sealing block 31 and the cup body 1 to achieve a seal. At this time, the abutment component 44 moves downward with the pressure rod 41 until it engages with the sleeve 42, thereby restraining the movement of the pressure rod 41. At the same time, the abutment component 44 contacts the locking component 45 and connects it to the cup body 1 to prevent the cup body 1 from separating from the cup lid 2. When it is necessary to open the cup body, the user presses the locking component 45 to separate it from the cup body 1. At this time, the locking component 45 causes the abutment component 44 to no longer engage with the sleeve 42 and separates it from the sleeve. The first elastic unit loses its restraint and drives the sealing block 31 to move upward through the pressure rod 41.

[0047] In this invention, when the cup body 1 needs to be closed, the user presses down the pressure rod 41, causing the sealing block 31 to move downwards and contact the sealing ring 32. The sealing block 31 is compressed to seal the inner cavity of the cup body 1. At this time, the abutment component 44 engages with the sleeve 42, thereby restraining the movement of the pressure rod 41. Simultaneously, the abutment component 44 connects the locking component 45 to the cup body 1, thereby connecting the cup lid 2 to the cup body 1. When the cup body needs to be opened, the user presses the locking component 45 to separate it from the cup body 1. There is no need for the user to exert force to turn the cup lid 2, which saves effort and ensures ease of use.

[0048] Preferably, the first elastic unit 43 can be a tension spring as in the prior art.

[0049] In one embodiment, two snap-fit ​​grooves 11 are symmetrically formed on the top of the inner wall of the cup body 1, and a sliding groove 22 corresponding to each snap-fit ​​groove 11 is formed at the bottom of the first chamber 21;

[0050] The locking assembly 45 includes two opposing push rods 451 that are radially slidably inserted into the side wall of the cup lid 2. The protruding end of each push rod 451 extends to the outer wall of the cup lid 2, and its inserted end is detachably connected to the abutment assembly 44. When the abutment assembly 44 contacts the push rod 451, it applies a pushing force to it in a direction away from the axis of the cup body 1.

[0051] The bottom of the cup lid 2 is also symmetrically provided with two locking blocks 452 corresponding to each locking slot 11. When each locking block 452 is inserted into the corresponding locking slot 11, the cup lid 2 is connected to the cup body 1.

[0052] Each push rod 451 is also provided with a connecting rod 453 between it and the corresponding locking block 452, and each connecting rod 453 forms a sliding fit with the corresponding sliding groove 22. Each push rod 451 drives the corresponding locking block 452 to move closer to or further away from the axis of the cup body 1 through the connecting rod 453.

[0053] With this design, when the abutting component 44 contacts each push rod 451, the abutting component 44 applies a pushing force to each push rod 451 in a direction away from the axis of the cup body 1. At this time, each push rod 451 drives the corresponding locking block 452 to move away from the axis of the cup body 1 through the connecting rod 453 until each locking block 452 is inserted into the corresponding locking groove 11. At this time, the cup lid 2 is connected to the cup body 1. When it is necessary to open the cup body 1, the user applies a squeezing force to each push rod 451 in a direction close to the axis of the cup body 1. Each push rod 451 causes the abutting component 44 to retract into the sleeve 42 and drives each locking block 452 to separate from the corresponding locking groove 11. At the same time, the first unit loses its constraint and drives the pressure rod 41 to move upward, the sealing block 31 separates from the sealing ring 32, and the cup lid 2 loses its constraint from the cup body 1.

[0054] In one embodiment, the sleeve 42 is provided with two symmetrical openings 421;

[0055] The abutting assembly 44 includes two abutting blocks 441 that are slidably disposed in the pressure rod 41 and correspond one-to-one with each opening 421. When each abutting block 441 extends out of the sleeve 42 through the opening 421, each abutting block 441 constrains the pressure rod 41 to move and contacts the corresponding push rod 451.

[0056] A second elastic unit 442 is also provided between each abutment block 441 and the pressure rod 41, which is used to apply a thrust to the corresponding abutment block 441 in a direction away from the axis of the cup body 1.

[0057] With this design, when the pressure rod 41 moves downward, each abutment block 441 moves together with the pressure rod 41 until each abutment block 441 moves to the position of the corresponding opening 421. At this time, the second unit loses its constraint and drives the corresponding abutment block 441 to extend into the opening 421, so that the corresponding abutment block 441 contacts the corresponding push rod 451 and applies a pushing force to it in a direction away from the axis of the cup body 1. At this time, each abutment block 441 engages with the sleeve 42 and constrains the movement of the pressure rod 41. When the user presses the push rod 451, each push rod 451 applies a pushing force to the corresponding abutment block 441 in a direction closer to the axis of the cup body 1 until each abutment block 441 is retracted into the sleeve 42. At this time, the first elastic unit 43 loses its constraint and drives the pressure rod 41 to move upward.

[0058] Preferably, the second elastic unit 442 can be a spring from the prior art.

[0059] In one embodiment, a third elastic unit 5 is provided between each push rod 451 and the cup lid 2, for applying an elastic force to the corresponding push rod 451 in the direction close to the axis of the cup body 1.

[0060] It should be noted that the cross-sectional area of ​​the push rod 451 is larger than the area of ​​the opening 421, so that when the push rod 451 is not in contact with the abutment block 441, the push rod 451 will not extend into the sleeve 42 through the opening 421, thus ensuring that the abutment block 441 works normally.

[0061] With this design, when the push rod 451 moves away from the axis of the cup body 1, the third elastic unit 5 is compressed. When the user presses the push rod 451, the third elastic unit 5 assists the push rod 451 in applying a pushing force to the corresponding abutment block 441 in the direction closer to the axis of the cup body 1, making the user's operation easier. At the same time, when the push rod 451 is not in contact with the abutment block 441, the third elastic unit 5 is used to restrain the movement of the push rod 451, so as to avoid unnecessary movement of the push rod 451 when the user carries the cup body 1.

[0062] It should be noted that the elastic force of the second elastic unit 442 is greater than that of the third elastic unit 5, but less than the sum of the elastic force of the third elastic unit 5 and the force applied by the user. This ensures that each push rod 451 works normally, while preventing the push rod 451 from accidentally pushing the abutment block 441 into the sleeve 42.

[0063] Preferably, the third elastic unit 5 can be a spring from the prior art.

[0064] In one embodiment, two second chambers 12 are symmetrically formed in the cup body 1, and each chamber is provided with a guide groove 13, and each guide groove 13 surrounds the protruding end of the corresponding push rod 451.

[0065] The cup lid 2 is also provided with a limiting component 6, including a pressure cap 61 that is rotatably and slidably inserted into each of the second chambers 12, and each pressure cap 61 is rotatably connected to the protruding end of the corresponding top rod 451.

[0066] Each cap 61 has a limiting block 62 that slides in the corresponding guide groove 13 at its extended end. When the limiting block 62 is misaligned with the guide groove 13, the limiting block 62 constrains the cap 61 to move toward the axis of the cup body 1.

[0067] With this design, when the push rod 451 moves away from the axis of the cup body 1, the pressure cap 61 moves with it until the limiting block 62 exits the guide groove 13. Then, the user rotates the pressure cap 61 to misalign the limiting block 62 with the guide groove 13. At this time, the limiting block 62 constrains the movement of the push rod 451 through the pressure cap 61 to prevent the cup lid 2 from accidentally separating from the cup body 1 due to external factors such as accidental touch by the user. When it is necessary to open the cup body 1, the user reverses each pressure cap 61 to make the limiting block 62 correspond to the guide groove 13 and presses the pressure rod 41.

[0068] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0069] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
