Description

Technical Field

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

[0002] Thermos flasks are a common drinking tool. Their excellent heat retention and portability allow users to enjoy hot water anytime, anywhere, making them popular, especially among children who consider them indispensable for daily outings. To facilitate carrying, most thermos flasks are equipped with straps or shoulder straps, allowing users to hang them around their neck or shoulder to reduce the burden on their hands.

[0003] Currently, there are two main ways to set up straps on insulated cups: one is to fix the strap directly to the container, with the strap always attached to the cup body; the other is to detach the strap and attach it to the cup body, so that the strap is attached when in use and removed when not in use. For children's insulated cups, the detachable strap design is particularly common—with the strap removed, the insulated cup can be used as a regular water cup, suitable for everyday home or school scenarios where carrying it is not required; with the strap attached, it is convenient for children to wear diagonally or on their back when going out, making it easy to carry and switching between the two usage modes of the insulated cup.

[0004] However, the aforementioned detachable strap design still has significant drawbacks in practical use. After removal, the strap lacks a fixed storage location; users typically have no choice but to place it haphazardly elsewhere or leave it hanging on the cup. This design without a fixed storage location has the following shortcomings: Firstly, the strap is easily lost, and users often can't find it when they need it again, especially with children's thermos cups, where strap loss is even more frequent. Secondly, the exposed strap is easily soiled, affecting hygiene and appearance. Furthermore, even if the user leaves the strap on the cup, the dangling strap will cause inconvenience during daily use (such as pouring water, washing, or placing it on a table), affecting the container's usability and appearance. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a modular, detachable thermos cup, aiming to solve the problems of existing thermos cups having difficulty in storage, easy loss, and affecting the normal use of the cup after the strap is removed.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a modular detachable thermos cup, comprising a cup body, a cup lid and a hanging component, wherein the bottom of the cup body is provided with a base and the base is provided with a storage cavity for storing the hanging component; The mounting bracket includes a scroll located in the middle, a hanging strap symmetrically located on both sides of the scroll and fixedly connected to the scroll, and a connecting part located at the end of the hanging strap and connected to the base. The storage cavity has a rotating seat at the center of the bottom that cooperates with the scroll. The connecting part is rotatably connected to the base to change the connection direction of the hanging part; After the scroll is engaged with the rotating seat, the scroll rotates to store the hanging parts, thereby storing the hanging parts in the storage cavity. The base is equipped with a removable bottom cover.

[0007] In the above scheme, preferably, the rotating seat is fixed on the base, the rotating seat is a magnet, the rotating seat is provided with a positioning hole, the scroll is made of magnetic material, and it is provided with a positioning rod that cooperates with the positioning hole.

[0008] In the above scheme, preferably, the connecting part includes a connecting rod connected to the hanging strap and a rotating part connected to the base. The rotating part is provided with rotating pins symmetrically on both sides. The base is provided with a groove that cooperates with the rotating part. The rotating pins are rotatably located on both sides of the groove.

[0009] In the above scheme, preferably, one end of the connecting rod is connected to the hanging strap, and the other end is provided with a pull rope that cooperates with the rotating part. An elastic pin is slidably provided on the rotating part, and the elastic pin is connected to the pull rope. The bottom cover is provided with a pin hole that mates with the elastic pin.

[0010] In the above scheme, preferably, a drive spring is provided between the elastic pin and the rotating part.

[0011] In the above scheme, preferably, the bottom cover is provided with a drive rod, one end of the roller is provided with a positioning rod that cooperates with the positioning hole, and the other end is provided with a drive hole that cooperates with the drive rod; The rotation of the bottom cover drives the drive rod to rotate, which in turn drives the drive hole to rotate the roller, thereby driving the elastic pin. When the pin hole on the bottom cover and the elastic pin are in the corresponding area, release the bottom cover and rotate it counterclockwise so that the elastic pin can be inserted into the pin hole by the drive spring, thus assembling the bottom cover.

[0012] In the above scheme, preferably, a groove for the pull rope to pass through is provided at the end of the pin hole away from the bottom of the bottom cover, and the groove extends from the pin hole toward the opening of the bottom cover. The outer edge dimension of the rotating component is larger than the diameter of the connecting rod, and the diameter of the connecting rod is the same as or close to the diameter of the elastic pin.

[0013] In the above scheme, preferably, the cup body and the cup lid are fitted with a hanging ring, the hanging ring is symmetrically provided with hanging pins, and the hanging strap is provided with a hanging hole that cooperates with the hanging pin. The hanging hole is a "gourd hole". When the strap is located outside the thermos, the pull rope is tightened to compress the drive spring, causing the large hole of the gourd to pass through the outer end limit plate of the hook pin. After the strap is released, the return force of the drive spring causes the small hole of the gourd to engage with the pin of the hook pin.

[0014] In the above scheme, preferably, the initial elastic force of the driving spring is greater than or equal to the gravity of the thermos cup when it is fully loaded.

[0015] In the above scheme, preferably, the bottom of the bottom cover has several hollowed-out parts.

[0016] The beneficial effects of this invention are as follows: By setting a base and storage cavity at the bottom of the cup body and setting a scroll in the middle of the hook, and cooperating with the rotating seat in the base, the hook strap can be quickly coiled and stored in the storage cavity at the bottom of the cup body after disassembly, effectively avoiding the problems of hook strap loss and dirt; at the same time, the hook is rotatably connected to the base through the connecting part, and the hook strap can be pulled out and flipped to both sides of the cup body when in use, and the connection direction is flexible and changeable to adapt to different carrying habits; The magnetic rotating seat, along with the positioning rod and positioning hole, enables quick and stable positioning of the reel, making operation simple. The use of a spring-loaded pin, pull rope, drive spring, and bottom cover pin hole allows for quick locking and unlocking between the bottom cover and the hanging device. Simultaneously, when the strap is unfolded, the gourd hole at the end of the strap engages with the hanging pin, automatically locking itself using the restoring force of the drive spring, ensuring reliable carrying connection and maintaining the strap's tension to prevent loosening and enhance safety. The perforated section at the bottom of the bottom cover facilitates the drainage of moisture accumulated in the storage cavity, keeping the cavity dry and hygienic. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1-8 .

[0026] A modular detachable thermos cup includes a cup body 1, a cup lid 2, and a hanging component 3. The cup body 1 is used to hold drinking water. The cup lid 2 is screwed or fastened to the top opening of the cup body 1 to achieve heat preservation and sealing. The conventional structure of the thermos cup will not be described in detail here. The hanging component 3 is a flexible component used to carry or hang the thermos cup on the user's body or external objects.

[0027] like Figure 2 and Figure 3 As shown, a base 101 is fixedly installed at the bottom of the cup body 1. The base 101 can be an integral structure with the cup body 1, or it can be an independent component fixed to the bottom of the cup body 1 by means of snap-fit, riveting, gluing or welding. The end of the base 101 away from the cup body 1 is open, and the open end and the wall of the base 101 form a storage cavity 102. The storage cavity 102 is used to accommodate and store the hanging part 3. A detachable bottom cover 104 is provided at the lower opening of the base 101. The bottom cover 104 is used to close the opening of the storage cavity 102 to prevent the hanging part 3 from falling out of the storage cavity 102, and can be removed by the user when needed to take out or store the hanging part 3.

[0028] like Figures 2 to 7 As shown, the hanger 3 has a strip-like structure, including a scroll 301, hanging straps 302, and connecting parts 303. The scroll 301 is located in the middle of the hanger 3. There are two hanging straps 302, which are symmetrically connected to the left and right sides of the scroll 301, and the hanging straps 302 are fixedly connected to the scroll 301. The scroll 301 has a columnar structure, with protrusions larger than the diameter of the column at both ends. Each hanging strap 302 has a connecting part 303 at its end away from the scroll 301. The connecting part 303 is used to rotatably connect to the base 101 to fix the hanger 3 as a whole onto the base 101.

[0029] A rotating seat 103 is located at the center of the bottom of the storage cavity 102. The rotating seat 103 is adapted to the shape and size of the scroll 301. When the hook 3 is stored in the storage cavity 102, the scroll 301 is placed on the rotating seat 103 and can rotate freely relative to the rotating seat 103. Through the rotational movement of the scroll 301 on the rotating seat 103, the hook straps 302 on both sides can be gradually wound around the outer circumference of the scroll 301, thereby completely gathering the hook straps 302 inside the storage cavity 102. When it is necessary to remove the hook straps 302 for use, the user can rotate the scroll 301 in the opposite direction or directly pull the scroll 301 and the hook straps 302 outwards simultaneously, so that the hook straps 302 are unwound from the scroll 301 and placed outside the storage cavity 102.

[0030] The connecting part 303 is rotatably connected to the base 101, meaning that the connecting part 303 can rotate around a certain axis on the base 101. When the hanging strap 302 is pulled out of the storage cavity 102, the connecting part 303 can rotate relative to the base 101 at a certain angle, thereby changing the extension direction of the hanging strap 302 relative to the cup body 1, i.e., from... Figure 2 The state shown is formed after rotation Figure 7 As shown in the diagram. Specifically, the strap 302 can be flipped up from the bottom of the cup body 1 to the side of the cup body 1 during use, so that the user can carry it on their back.

[0031] The rotating seat 103 is fixedly disposed at the center of the bottom of the storage cavity 102 of the base 101. In this embodiment, the rotating seat 103 is preferably a permanent magnet. A positioning hole 11 is provided at the center of the rotating seat 103. The positioning hole 11 is circular. The scroll 301 is made entirely of a magnetic material, such as iron, or the scroll 301 is provided with at least one magnetic layer that cooperates with the rotating seat 103. A positioning rod 12 is fixedly disposed on one end face of the scroll 301 facing the rotating seat 103. The position of the positioning rod 12 corresponds to the position of the positioning hole 11, and the shape of the positioning rod 12 is adapted to the shape of the positioning hole 11. When the scroll 301 is placed on the rotating seat 103, the positioning rod 12 is inserted into the positioning hole 11 to achieve radial positioning of the scroll 301 on the rotating seat 103 and prevent the scroll 301 from eccentrically shifting during rotation. At the same time, the magnetic attraction of the rotating seat 103 generates an axial attraction effect on the scroll 301, so that the scroll 301 can be stably attached to the rotating seat 103. Even if the cup body 1 is tilted or inverted, the scroll 301 is not easy to fall off the rotating seat 103. Then, the user can rotate the scroll 301 by holding the outer end of the scroll 301 with his / her fingers. Preferably, an anti-slip texture can be provided on the outer edge of the boss at the end of the scroll 301 away from the positioning rod 12 for easy gripping.

[0032] The connecting part 303 specifically includes a connecting rod 31 and a rotating member 32. One end of the connecting rod 31 is fixedly connected to the end of the hanging strap 302, and the other end of the connecting rod 31 is connected to the rotating member 32. The rotating member 32 is used to achieve a rotatable connection with the base 101, such as... Figure 4 As shown, rotating pins 33 are symmetrically protruding on the left and right sides of the rotating component 32. The two rotating pins 33 are coaxially arranged. The side wall of the opening side of the base 101 is provided with a slot 34 that matches the rotating component 32. The two side walls of the slot 34 are provided with shaft holes corresponding to the rotating pins 33. The rotating pins 33 are rotatably installed in the shaft holes on both sides of the slot 34, so that the rotating component 32 can swing around the axis of the rotating pins 33 in the slot 34, driving the connecting rod 31 and the hanging strap 302 to change their orientation.

[0033] One end of the connecting rod 31 is connected to the hanging strap 302, and the other end of the connecting rod 31 is connected to a pull rope 35, such as Figure 3 As shown, the pull cord 35 is a flexible cord that passes through the rotating component 32 and is connected to the elastic pin 36. The elastic pin 36 is slidably mounted on the rotating component 32, and the axial direction of the elastic pin 36 is consistent with the direction of the pulling force of the pull cord 35. The bottom cover 104 has a pin hole 37, the position of which corresponds to the position of the elastic pin 36. When the bottom cover 104 is closed at the open end of the base 101, the elastic pin 36 can be inserted into the pin hole 37, thereby locking the bottom cover 104 and the rotating component 32, preventing the bottom cover 104 from being opened arbitrarily. When the user pulls the pull cord 35, the pull cord 35 drives the elastic pin 36 to slide against the external force into the rotating component 32, causing the elastic pin 36 to disengage from the pin hole 37, at which point the bottom cover 104 can be opened.

[0034] A drive spring 38 is also provided between the elastic pin 36 and the rotating member 32. The drive spring 38 is sleeved on the outer periphery of the elastic pin 36 or disposed between the elastic pin 36 and the inner wall of the rotating member 32. One end of the drive spring 38 abuts against the rotating member 32, and the other end abuts against the elastic pin 36. The drive spring 38 always applies an elastic thrust toward the pin hole 37 to the elastic pin 36. When the user releases the pull rope 35, the drive spring 38 pushes the elastic pin 36 to automatically reset and insert it into the pin hole 37.

[0035] A drive rod 13 is fixedly mounted on one end face of the bottom cover 104 facing the inside of the storage cavity 102. The drive rod 13 protrudes from the inner surface of the bottom cover 104. A drive hole 14 is provided on one end face of the reel 301 facing the bottom cover 104. The shape of the drive hole 14 matches the shape of the drive rod 13. For example, both the drive rod 13 and the drive hole 14 can be set to non-circular cross-section shapes such as cross-shaped, straight, or hexagonal. When the bottom cover 104 is closed on the base 101, the drive rod 13 is inserted into the drive hole 14. When the user manually rotates the bottom cover 104, the bottom cover 104 drives the drive rod 13 to rotate, and the drive rod 13 then drives the reel 301 to rotate synchronously through the drive hole 14, thereby realizing the coiling and storage of the strap 302. During the storage process, the user continues to rotate the bottom cover 104 until the strap 302 is completely retracted into the storage cavity 102. At this time, the pin hole 37 on the bottom cover 104 is just rotated into the area corresponding to the elastic pin 36. At this time, the user releases the bottom cover 104 and rotates it slightly counterclockwise (or in the preset direction). The elastic pin 36 is automatically inserted into the pin hole 37 under the elastic thrust of the drive spring 38, thereby locking the bottom cover 104 onto the base 101 and completing the assembly after storage.

[0036] A groove 4 is formed at the end of the pin hole 37 away from the bottom of the bottom cover 104 (i.e., the end closer to the interior of the base 101). The groove 4 extends from the end of the pin hole 37 toward the opening of the bottom cover 104. The width of the groove 4 is adapted to the diameter of the pull rope 35 for the pull rope 35 to pass through; the outer edge dimension of the rotating member 32 is larger than the diameter of the connecting rod 31, and the diameter of the connecting rod 31 is the same as or close to the diameter of the elastic pin 36. With this configuration, when the hanging strap 302 is removed, the rotating member 32 rotates 180° to... Figure 7 In the state shown, when the strap 302 is pulled out, the connecting rod 31 pulls the pull rope 35 a certain distance outside the rotating member 32. At this time, the drive spring 38 is compressed, and the bottom cover 104 can be reinstalled on the base 101 through the cooperation of the wire groove 4 and the pull rope 35, further positioning the pull rope 35 in the center of the pin hole 37. Then the strap 302 is released, and the connecting rod 31 can be inserted into the pin hole 37, forming a stepped limiting structure with the rotating member 32 and the bottom cover 104.

[0037] A hook ring 5 is fitted onto the joint end face of the cup body 1 and the cup lid 2. The hook ring 5 is circular and fits around the neck of the cup body 1 or the outer periphery of the threaded connection between the cup body 1 and the cup lid 2. The hook ring 5 extends a certain distance towards the side wall on both sides to form an extension, and two hook pins 501 are symmetrically arranged on the extension. The hook pin 501 is a rod-shaped structure with a limiting plate at the outer end. The diameter of the limiting plate is larger than the diameter of the pin in the middle of the hook pin 501. The hanging strap 302 has a hanging hole 502 that mates with the hook pin 501. The hanging hole 502 is a "gourd hole", that is, the hanging hole 502 is formed by a large hole and a small hole connected together. The diameter of the large hole is larger than the diameter of the limiting plate at the outer end of the hook pin 501, and the diameter of the small hole is between the diameter of the limiting plate and the diameter of the pin.

[0038] When the strap 302 needs to be attached to the upper part of the cup body 1 for carrying, the user first removes the attachment 3 from the storage cavity 102 and flips the strap 302 upwards to the outside of the cup body 1. Then, the user pulls the pull cord 35, causing the pull cord 35 to drive the elastic pin 36 to slide inwards against the elastic force of the drive spring 38, at which point the connecting rod 31 connected to the pull cord 35 and the strap 302 gain a certain amount of play. The user aligns the large hole of the hanging hole 502 at the end of the strap 302 with the outer end limiting plate of the attachment pin 501 and slips it on, then releases the pull cord 35. Under the restoring force of the drive spring 38, the elastic pin 36 slides outward to return to its original position. Simultaneously, the pull rope 35 pulls the connecting rod 31 and the hanging strap 302, causing the hanging hole 502 to move relative to the hook pin 501. This allows the smaller hole of the hanging hole 502 to engage with the pin of the hook pin 501, while the limiting plate prevents the hanging strap 302 from detaching from the hook pin 501, thus achieving a reliable engagement between the hanging strap 302 and the hook ring 5. When it is necessary to remove the hanging strap 302, pull the pull rope 35 again to realign the larger hole of the hanging hole 502 with the limiting plate, allowing the hanging strap 302 to be removed from the hook pin 501.

[0039] In this embodiment, the initial elastic force of the drive spring 38 is set to be greater than or equal to the total weight of the thermos when fully loaded. Thus, when the strap 302 is engaged with the hook pin 501 through the gourd hole, the restoring force of the drive spring 38 is sufficient to overcome the weight of the thermos when fully loaded, ensuring that the strap 302 remains taut during carrying and will not accidentally detach from the hook pin 501 due to the weight of the thermos. Furthermore, when disassembly is required, the user only needs to gently pull the pull cord 35 to overcome the elastic force, making the operation convenient, safe, and reliable.

[0040] The bottom of the base cover 104 (i.e., the surface exposed below the base 101) has several perforations 15. These perforations 15 connect the storage cavity 102 to the outside atmosphere. If water accidentally accumulates on the surface of the cup 1 or inside the storage cavity 102, the moisture can be drained through the perforations 15 in a timely manner, preventing dampness and mold growth inside the storage cavity 102 and helping to keep the hanging component 3 clean and dry. Simultaneously, the perforations 15 also allow the user to easily observe the storage status of the hanging component 3 inside the storage cavity 102.

[0041] In this embodiment, the diameter of the pin hole 37 can be slightly larger than the diameter of the elastic pin 36. At the same time, the pin hole 37 can also be a long slot provided around the circumference of the bottom cover 104, so that the elastic pin 36 and the bottom cover 104 can rotate and cooperate to realize the engagement and disengagement of the pin body and the pin hole 37.

[0042] Using a modular, detachable thermos cup as described above: Storage state: When the user does not need to use the hanging strap 302, the hanging piece 3 is placed in the storage cavity 102 of the base 101, so that the positioning rod 12 of the scroll 301 is inserted into the positioning hole 11 of the rotating seat 103 and is fixed by the magnetic attraction of the rotating seat 103. Then, the scroll 301 is manually rotated, and the hanging straps 302 on both sides are coiled around the outer circumference of the scroll 301. Continue to rotate until the hanging straps 302 are completely stored in the storage cavity 102. Then, the bottom cover 104 is closed on the open end of the base 101, so that the drive rod 13 on the bottom cover 104 is inserted into the drive hole 14 of the scroll 301. The user rotates the bottom cover 104 in the forward direction, and the bottom cover 104 drives the scroll 301 to rotate further through the drive rod 13. At this time, the pin hole 37 on the bottom cover 104 is aligned with the elastic pin 36 on the rotating piece 32. The elastic pin 36 is automatically inserted into the pin hole 37 under the action of the drive spring 38, locking the bottom cover 104. At this time, the thermos cup appears as follows Figure 1 The cup shown is in its standard form, with a clean appearance and convenient for daily use.

[0043] Unfolded and Carrying State: When the user needs to use the strap 302, the elastic pin 36 can be pressed externally to make the arc surface of the end of the elastic pin 36 initially contact the hole wall of the pin hole 37. Then, the bottom cover 104 is rotated and the pull rope 35 is pulled to completely disengage the elastic pin 36 from the pin hole 37, after which the bottom cover 104 can be removed. Then, the hook 3 is taken out from the storage cavity 102, and the strap 302 and the scroll 301 are taken out as a whole. The connecting part 303 is flipped around the rotating pin 33 so that the strap 302 extends from the bottom of the cup body 1 to both sides of the cup body 1. Next, the gourd hole at the end of the strap 302 is aligned with the limiting plate of the hook pin 501 on the hook ring 5 and inserted. Release the pull rope 35, and the drive spring 38 returns to its original position. Pulling the pull rope 35 causes the hanging strap 302 to engage with the pin of the hook pin 501. During this process, when the hanging strap 302 is pulled out, the connecting rod 31 pulls the pull rope 35 a certain distance beyond the rotating part 32. At this time, the drive spring 38 is compressed, and the bottom cover 104 can be reinstalled on the base 101 through the cooperation of the wire groove 4 and the pull rope 35, further positioning the pull rope 35 at the center of the pin hole 37. Subsequently, when the hanging strap 302 is released, the connecting rod 31 can be inserted into the pin hole 37, forming a stepped limiting structure with the rotating part 32 and the bottom cover 104. Figure 7 As shown, the straps 302 are reliably fixed to both sides of the upper end of the cup body 1. The user can carry the thermos cup on their back through the straps 302. At the same time, since the elastic force of the drive spring 38 is greater than the weight of the full-loaded cup, the straps 302 will not come loose during the carrying process.
