Description

Technical Field

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

[0002] A thermos flask is a container that achieves its function of keeping food hot or cold through a vacuum insulation layer or insulation material. The main body is made of double-layered stainless steel or glass, with the interlayer evacuated to reduce heat conduction. Some high-end models are filled with copper foil, vacuum cotton, etc. to enhance heat insulation. The lid usually uses a sealing silicone ring, combined with a screw-on design to prevent liquid leakage. According to the use, they are divided into household, car, and outdoor types. Outdoor models often have additional anti-slip rubber and hanging ring designs. According to function, there are direct drinking cups, straw cups, and thermal cookers. Thermal cookers can use residual heat to cook food.

[0003] In existing technologies, the outer lid of a thermos cup is fastened to the mouth of the cup. To improve stability, a magnetic ring is installed inside the thermos cup and an iron ring is installed in the outer lid to achieve magnetic positioning. However, in the traditional magnetic attraction process, it is not convenient to adjust the magnetic force according to the user's needs, and it is difficult to meet the needs of different usage scenarios. For example, strong magnetic force is needed during outdoor sports to reduce the accidental fall of the outer lid, while moderate magnetic force and easy opening are desired for daily one-handed operation, resulting in overall inconvenience in use. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned above in the background technology by proposing a thermos cup with adjustable magnetic force.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a thermos cup with adjustable magnetic force function, comprising a thermos cup body, an upper shoulder provided on the outer surface of the thermos cup body, an outer cover provided on the upper part of the thermos cup body, and a stabilizing device provided on the surface of the thermos cup body;

[0006] The stabilizing device includes a magnetic ring installed between the thermos body and the upper shoulder. An iron ring is installed on the inner wall of the outer cover. Multiple supports are fixedly connected to the surface of the iron ring. A magnetic block is set between each of the supports and the iron ring. Two sets of guides are set between the magnetic block and the supports. An adjustment part is set on the support to adjust the position of the magnetic block. A rotating gear ring that can control the operation of the adjustment part is rotatably connected to the inner wall of the outer cover. Multiple through holes are opened on the surface of the iron ring for the magnetic block to pass through.

[0007] A positioning part is provided between the rotating gear ring and the outer cover to limit the rotation of the gear ring.

[0008] Preferably, the surface of the outer cover has multiple perforations for the magnetic block to pass through, and the surface of the upper shoulder has multiple grooves for the magnetic block to be inserted into the inner wall of the grooves. Through the above components, when the magnetic block moves further, it can pass through the perforations and be inserted into the grooves, which can further reduce the distance between it and the magnetic ring and improve the adsorption effect. At the same time, the magnetic block inserted into the grooves can also play a limiting role.

[0009] Preferably, an elastic sheet is fixedly connected to the inner wall of the second perforation. The elastic sheet is made of rubber. Through the above-mentioned components, when the magnetic block passes through the second perforation, it can cause the elastic sheet to deform and be squeezed into the groove together, thereby improving stability.

[0010] Preferably, the adjusting part includes a threaded sleeve fixed to the surface of the magnetic block, and an adjusting screw is rotatably connected to the inner wall of the bracket. The adjusting screw is threadedly connected to the inner wall of the threaded sleeve, and a gear is fixedly connected to one end of the adjusting screw. The gear meshes with a rotating gear ring. Through the above components, during adjustment, the rotating gear ring can be rotated, which can drive multiple sets of gears and the adjusting screw to rotate. The adjusting screw, in conjunction with the threaded sleeve, can drive the magnetic block to move, and the guiding part can perform guiding operations, thereby adjusting the distance between the magnetic block and the magnetic ring to achieve magnetic force adjustment.

[0011] Preferably, the guide part includes a guide rod fixed to the surface of the bracket, and a hollow sleeve is fixedly connected to the surface of the magnetic block. The guide rod is slidably connected to the inner wall of the hollow sleeve. Through the above components, the guide rod can move in the hollow sleeve when the magnetic block moves, thereby improving stability.

[0012] Preferably, the positioning part includes a fixing ring fixed to the surface of the outer cover, the surface of the fixing ring having multiple slots, the surface of the rotating gear ring being fixedly connected to an outer ring, the inner wall of the outer ring being slidably connected to two sliders, the surface of the sliders being fixedly connected to locking blocks, the locking blocks being inserted into the inner wall of the slots. Through the above components, when the magnetic force is adjusted, without rotating the rotating gear ring, the sliders are pushed to move, causing the locking blocks to engage in the corresponding slots on the surface of the fixing ring, thereby achieving the positioning operation.

[0013] Preferably, the two card blocks are symmetrically arranged with respect to the outer ring, and the card blocks are T-shaped.

[0014] Preferably, the inner wall of the slider is slidably connected with two pins, and a spring is fixedly connected to the side of the pin corresponding to the inner wall of the slider. The inner wall of the outer ring is provided with two sets of circular grooves for the slot to be inserted. Through the above components, when the slider drives the block to be inserted into the slot on the surface of the fixed ring, the spring drives the pin to be inserted into one set of circular grooves to achieve positioning. When the slider drives the block to be removed from the slot on the surface of the fixed ring, the spring and the pin can be inserted into the other set of circular grooves to achieve positioning.

[0015] Preferably, the surface of the slider is fixedly connected with multiple anti-slip plates.

[0016] Preferably, both the magnetic ring and the magnetic block are neodymium iron boron magnets.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] 1. In this utility model, by setting a stabilizing device, after the outer cover is snapped on and installed, the magnetic ring can attract the iron ring to achieve basic magnetic attraction limit. When it is necessary to adjust the magnetic force, simply rotate the rotating gear ring. The rotating gear ring controls the adjustment part to rotate and, together with the guide part, drives the magnetic block to move, thereby adjusting the distance between the magnetic block and the magnetic ring to achieve magnetic force adjustment. The magnetic force can be flexibly adjusted according to needs. When working in the office, the magnetic force can be reduced so that the lid can be easily opened with one hand; when carrying outdoors or in a car, the magnetic force can be increased to reduce the lid falling off during bumps and improve the overall practicality.

[0019] 2. In this utility model, when the magnetic block moves further, it can pass through the second through hole and squeeze the elastic sheet into the groove, further reducing the distance between it and the magnetic ring. At the same time, the groove and the elastic sheet squeeze into the groove can further improve stability.

[0020] 3. In this utility model, by setting a positioning part, the rotating gear ring can be positioned after the rotation adjustment operation, realizing the locking and anti-accidental touch function after magnetic adjustment, and improving the overall stability. Attached Figure Description

[0035] Example 1

[0036] refer to Figure 1 - Figure 7 The thermos cup shown includes a thermos cup body 1, an upper shoulder 3 on the outer surface of the thermos cup body 1, an outer cover 2 on the top of the thermos cup body 1, and a stabilizing device 4 on the surface of the thermos cup body 1.

[0037] The stabilizing device 4 includes a magnetic ring 41 installed between the thermos body 1 and the upper shoulder 3. An iron ring 42 is installed on the inner wall of the outer cover 2. Multiple supports 45 are fixedly connected to the surface of the iron ring 42. A magnetic block 43 is provided between each of the multiple supports 45 and the iron ring 42. Two sets of guide parts 46 are provided between the magnetic block 43 and the supports 45. An adjustment part 47 is provided on the supports 45 to adjust the position of the magnetic block 43. The inner wall of the outer cover 2 is rotatably connected to control the operation of the adjustment part 47. The rotating gear ring 48 has multiple through holes 44 on its surface for the magnetic block 43 to pass through. Both the magnetic ring 41 and the magnetic block 43 are neodymium iron boron magnets. The adjusting part 47 includes a threaded sleeve 473 fixed on the surface of the magnetic block 43. An adjusting screw 471 is rotatably connected to the inner wall of the bracket 45. The adjusting screw 471 is threadedly connected to the inner wall of the threaded sleeve 473. A gear 472 is fixedly connected to one end of the adjusting screw 471. The gear 472 meshes with the rotating gear ring 48.

[0038] In this embodiment: when the outer cover is fastened, the magnetic ring 41 can be attracted to the iron ring 42 to achieve a preliminary limiting effect. During adjustment, the rotating gear ring 48 can be rotated, which can drive multiple sets of gears 472 and adjusting screws 471 to rotate. The adjusting screws 471, in conjunction with the threaded sleeve 473, can drive the magnetic block 43 to move. The guide part 46 can perform guiding operations, thereby adjusting the distance between the magnetic block 43 and the magnetic ring 41 to achieve magnetic force adjustment.

[0039] The outer cover 2 has multiple perforations 410 on its surface, through which the magnetic block 43 passes. The upper shoulder 3 has multiple grooves 412 on its surface, through which the magnetic block 43 is inserted into the inner wall of the groove 412. An elastic sheet 411 is fixedly connected to the inner wall of the perforation 410. The elastic sheet 411 is made of rubber.

[0040] In this embodiment: when the magnetic block 43 moves further, it can pass through the second perforation 410 and be inserted into the groove 412, which can further reduce the distance between it and the magnetic ring 41 and improve the adsorption effect. At the same time, when the magnetic block 43 passes through the second perforation 410, it can drive the elastic sheet 411 to deform and be squeezed together in the groove 412, which improves stability.

[0041] The guide part 46 includes a guide rod 461 fixed on the surface of the bracket 45, and a hollow sleeve 462 fixedly connected to the surface of the magnetic block 43. The guide rod 461 is slidably connected to the inner wall of the hollow sleeve 462. When the magnetic block 43 moves, the guide rod 461 can move in the hollow sleeve 462 to improve stability.

[0042] A positioning part 49 is provided between the rotating gear ring 48 and the outer cover 2 to limit the rotation of the gear ring 48. The positioning part 49 includes a fixing ring 491 fixed to the surface of the outer cover 2. The surface of the fixing ring 491 has multiple slots. An outer ring 493 is fixedly connected to the surface of the rotating gear ring 48. Two sliders 492 are slidably connected to the inner wall of the outer ring 493. A locking block 494 is fixedly connected to the surface of the slider 492. The locking block 494 is inserted into the inner wall of the slot. The two locking blocks 494 are symmetrically arranged with the outer ring 493. Two pins 495 are slidably connected to the inner wall of the slider 492. A spring 496 is fixedly connected to the side of the pin 495 corresponding to the inner wall of the slider 492. Two sets of circular grooves 497 are provided on the inner wall of the outer ring 493 for slot insertion. The locking block 494 is T-shaped. Multiple anti-slip pieces are fixedly connected to the surface of the slider 492.

[0043] In this embodiment: after the magnetic force is adjusted, without rotating the rotating gear ring 48, the slider 492 is pushed to move, so that the locking block 494 is engaged in the corresponding slot on the surface of the fixing ring 491. After the slider 492 drives the locking block 494 into the slot on the surface of the fixing ring 491, the spring 496 drives the pin 495 to insert into a set of circular slots 497. After the slider 492 drives the locking block 494 out of the slot on the surface of the fixing ring 491, the spring 496 and the pin 495 can be inserted into another set of circular slots 497 to achieve positioning.

[0044] Working principle of this invention: During use, after the outer cover 2 is fastened, the magnetic ring 41 can initially attract the iron ring 42, achieving a limiting effect. When it is necessary to adjust the magnetic force, first push the slider 492 to move, causing the locking block 494 to move out of the slot on the surface of the fixing ring 491. The pin 495 loses its restraint on a set of circular slots 497 and, in conjunction with the spring 496, is inserted into another set of circular slots 497. At this time, the rotating gear ring 48 can be rotated. The rotating gear ring 48 can drive multiple sets of gears 472 and the adjusting screw 471 to rotate. The adjusting screw 471, in conjunction with the threaded sleeve 473, can drive the magnetic block 43 to move. The guide part 46 can perform guiding operation. This allows for adjustment of the distance between the magnetic block 43 and the magnetic ring 41, thus achieving magnetic force adjustment. When the magnetic block 43 moves further, it can pass through the second perforation 410 and be inserted into the groove 412, further reducing the distance between it and the magnetic ring 41 and improving the adsorption effect. At the same time, when the magnetic block 43 passes through the second perforation 410, it can cause the elastic sheet 411 to deform and be squeezed together in the groove 412, improving stability. After adjustment, the slider 492 can be pushed to reset, the locking block 494 can be inserted into the corresponding slot on the surface of the fixing ring 491, and the spring 496 can drive the pin 495 to be inserted into the initial circular groove 497, thus completing the overall adjustment operation.

[0047] In this implementation scheme: when the outer cover 2 is fastened, the outer cover 2 contacts the upper shoulder 3. At this time, the iron ring 53 can attract the magnetic sheet 52 to achieve positioning. Multiple sets of magnetic sheets 52 can be installed on the fixed frame ring 51 to achieve adjustment of the magnetic force.

[0050] In this implementation scheme: when the outer cover 2 is fastened, the outer cover 2 contacts the decorative shoulder ring 63. At this time, the iron ring 62 can be positioned with the magnetic block 61. Multiple sets of magnetic blocks 61 can be installed on the decorative shoulder ring 63 to adjust the magnetic force.
