Description

Technical Field

[0001] This utility model relates to the technical field of thermos cups, specifically a heat-insulating thermos cup that is scalding-proof. Background Technology

[0002] A thermos is a water container made of ceramic or stainless steel with a vacuum layer. It has a lid that is tightly sealed. The vacuum insulation layer slows down the heat dissipation of the liquid inside, thus achieving the purpose of keeping it warm.

[0003] In existing thermos cups, when filled with too much hot water, the internal space of the cup shrinks when the lid is closed, causing some of the hot water to overflow and potentially scald the user's hands.

[0004] Chinese patent CN220256215U discloses a scalding-proof, heat-insulating thermos cup, including a thermos cup body, a thermos cup lid, a lid heat insulation sheet, and a lid sealing sheet. The thermos cup lid is installed on the upper surface of the thermos cup body, and a flow guiding component is provided on the upper side of the annular side of the thermos cup body. Although this utility model only describes that its flow guiding component is used to guide hot water dripping when the thermos cup lid is opened, preventing the user from being scalded by the dripping hot water while holding the thermos cup, based on the description in this utility model, those skilled in the art can easily imagine that the flow guiding component can also prevent some of the hot water inside the cup from overflowing due to the pressure of the lid and scalding the user's hands.

[0005] However, in this invention, after the hot water overflows and is collected by the flow guiding component, it flows downwards through the drain hole and the guide vertical hole and drains out from the bottom of the thermos. The drained water drips onto the table, the floor, or the user's clothing, which is inconvenient for daily use. Furthermore, the flow guiding component in this invention is fixed to the thermos body, so the user cannot choose whether to install the flow guiding component according to their own usage habits.

[0006] Therefore, this utility model proposes a new technical solution to solve the problem that after the water is collected by the diversion component, it will drain from the bottom of the thermos and drip onto the table, the ground, or the user's clothes, which is inconvenient for daily use. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heat-insulating and anti-scalding cup, which aims to collect and drain the overflowing water into the annular mounting groove, where it is absorbed by the annular water-absorbing block. This can prevent hot water inside the cup from overflowing due to the pressure of the cup lid and scalding people's hands, and can also prevent water from dripping from the bottom of the cup onto the table, the ground or the user's clothes.

[0008] A heat-insulating and scalding-proof thermos cup includes a thermos cup body, which comprises a cup body and a cup lid. A flow guiding component is fitted onto the outside of the cup body. The flow guiding component includes a bottom plate, an annular side plate, and a flow guiding ring. The bottom plate is detachably connected to the bottom end of the cup body. The annular side plate is integrally formed at the top edge of the bottom plate and fitted onto the outside of the cup body, with a gap between them. The flow guiding ring is integrally formed at the top of the annular side plate. A plurality of arc-shaped water guiding grooves are arranged in a ring array at the top edge of the bottom plate, with each arc-shaped water guiding groove corresponding to a gap. An annular mounting groove communicating with the arc-shaped water guiding grooves is formed at the bottom edge of the bottom plate. An annular water-absorbing block is installed in the annular mounting groove, and an annular cover plate is closed at the opening of the annular mounting groove.

[0009] By adopting the above technical solution, water overflowing from the cup opening is collected by the drainage ring and flows through the interval and arc-shaped water guide groove before entering the annular mounting groove, where it is absorbed by the annular water-absorbing block. This prevents hot water inside the cup from overflowing due to the pressure of the cup lid and scalding the user's hands, and also prevents water from dripping from the bottom of the thermos onto the table, floor, or the user's clothing.

[0010] A further feature of this invention is that the inner diameter of the top opening of the drainage ring is larger than that of the annular side plate.

[0011] By adopting the above technical solution, it is ensured that the overflowing water can flow into the drainage ring.

[0012] A further feature of this invention is that the inner wall of the drainage ring is configured as a downwardly inclined surface.

[0013] By adopting the above technical solution, the water flowing into the drainage ring can quickly flow into the interval through the inclined surface.

[0014] A further feature of this invention is that an annular protrusion is integrally formed on one side wall of the annular mounting groove, an annular slot is provided on the annular cover plate for inserting the annular protrusion, a receiving groove is provided at the bottom end of the base plate, a lever is integrally formed on the wall of the receiving groove, and a gap is maintained between the lever and the opening of the receiving groove for inserting a user's finger.

[0015] By adopting the above technical solution, when the annular cover plate is placed on the opening of the annular mounting groove, the annular protrusion inserts into the annular retaining groove, thereby fixing the annular cover plate in place. When it is necessary to remove the annular cover plate, insert your finger into the gap and use the lever to move the annular cover plate to remove it.

[0016] Further features of this invention: A connecting groove is provided at the middle of the bottom end of the cup body, and two locking holes are provided on the groove wall. A receiving groove is provided at the middle of the bottom end of the base plate. A connecting rod is fixed on the base plate, with the bottom end of the connecting rod located in the receiving groove. The top end of the connecting rod passes through the base plate and is inserted into the connecting groove in a mating connection manner. An inner cavity is provided inside the connecting rod, and two sliding rods are slidably connected in the inner cavity. A spring is fixedly connected between the two sliding rods. A pressing rod and a locking rod are fixedly connected to opposite ends of the two sliding rods. The other end of the pressing rod extends out of the connecting rod in a slidable connection manner and is located in the receiving groove. The other end of the locking rod extends out of the connecting rod in a slidable connection manner and is inserted into the locking hole in a mating connection manner.

[0017] By employing the above technical solution, when the flow guide assembly needs to be disassembled, the user presses the two pressing rods with two fingers respectively, thereby driving the two sliding rods to move towards each other along the inner cavity wall. The spring is compressed, generating a rebound force towards the outside of the inner cavity. The sliding rods drive the locking rod to move into the cavity. When the end of the locking rod that was originally inserted into the locking hole is completely pulled out of the locking hole, the connecting rod can be pulled out from the connecting groove, thereby removing the flow guide assembly from the cup body. Similarly, when the flow guide assembly needs to be installed, first press the pressing rod, then insert the connecting rod into the connecting groove, and then release the pressing rod. Under the action of the spring's rebound force, one end of the locking rod is inserted into the locking hole, thereby installing the flow guide assembly on the outside of the cup body.

[0018] A further feature of this invention is that a plurality of inserts are integrally formed on the inner wall of the annular side plate, with the plurality of inserts corresponding to the space between two adjacent arc-shaped water guide grooves, and slots for inserting the inserts are provided on the outer wall of the cup body.

[0019] By adopting the above technical solution, when installing the flow guiding component, the insert strip is inserted into the slot, which serves two purposes: firstly, it provides positioning, facilitating quick alignment of the clamping rod and the clamping hole; secondly, it enhances the structural strength of the annular side plate.

[0029] 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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] A type of heat-insulating and scalding-proof thermos, such as Figures 1-4 As shown, the thermos includes the main body of the thermos. The main body of the thermos includes a cup body 1 and a cup lid 2. A connecting groove 3 is provided at the middle of the bottom of the cup body 1. A locking hole 4 is provided on both the left and right sides of the connecting groove 3. Four slots 5 are arranged in a ring array on the outer side wall of the cup body 1.

[0031] The cup body 1 is fitted with a flow guiding assembly made of plastic material. The flow guiding assembly includes a base plate 6, an annular side plate 7, and a flow guiding ring 8.

[0032] The top of the base plate 6 is attached to the bottom of the cup body 1. Four arc-shaped water guide grooves 9 are arranged in a ring array at the top edge of the base plate 6.

[0033] A receiving groove 10 is provided at the middle of the bottom end of the base plate 6. A connecting rod 11 is fixed on the base plate 6. The bottom end of the connecting rod 11 is located inside the receiving groove 10. The top end of the connecting rod 11 passes through the base plate 6 and is inserted into the connecting groove 3 in a mating connection manner. An inner cavity 12 is provided inside the connecting rod 11. Two sliding rods 13 are slidably connected inside the inner cavity 12. Both sliding rods 13 slide against the cavity wall of the inner cavity 12. A spring 14 is fixedly connected between the two sliding rods 13. A pressing rod 15 and a locking rod 16 are fixedly connected to opposite sides of the two sliding rods 13. The other end of the pressing rod 15 passes through the connecting rod 11 in a slidable connection manner and is located inside the receiving groove 10. The other end of the locking rod 16 passes through the connecting rod 11 in a slidable connection manner and is inserted into the locking hole 4 in a mating connection manner. An annular mounting groove 17 is provided at the bottom edge of the base plate 6. The top end of the annular mounting groove 17 communicates with the bottom end of the arc-shaped water guide channel 9. The base plate 6 has evaporation holes 18 on its side wall, identical to those in the annular mounting groove 17. An annular protrusion 19 is integrally formed on one side wall of the annular mounting groove 17. The cross-section of the annular protrusion 19 is arc-shaped. An annular absorbent block 20 is installed inside the annular mounting groove 17. An annular cover plate 21 covers the opening of the annular mounting groove 17. An annular slot 22 is formed on the annular cover plate 21 for inserting the annular protrusion 19. A groove 23 is formed at the bottom end of the base plate 6. A lever 24 is integrally formed on the groove wall of the groove 23. A gap is maintained between the lever 24 and the opening of the groove 23 for inserting a user's finger.

[0034] The annular side plate 7 is integrally formed at the top edge of the base plate 6 and fits onto the outside of the cup body 1, with a gap between it and the cup body 1 corresponding to the arc-shaped water guide groove 9. Four inserts 25 are integrally formed between the inner wall of the annular side plate 7 and the top of the base plate 6. The four inserts are located between two adjacent arc-shaped water guide grooves 9 and are inserted into four slots 5 respectively.

[0035] The drainage ring 8 is integrally formed on the top of the annular side plate 7. The inner diameter of the top opening of the drainage ring 8 is larger than that of the annular side plate 7, ensuring that overflowing water can flow into the drainage ring 8. The inner wall of the drainage ring 8 is set as a downward sloping surface, so that the water flowing into the drainage ring 8 can quickly flow into the interval through the sloping surface.

[0036] The annular absorbent block 20 in this embodiment can be made of absorbent cotton material. Alternatively, it can be made of sandy ceramic material using Han pottery techniques (i.e., using the same material as the absorbent dry tea tray in the prior art, which has high water absorption efficiency and low manufacturing cost, and is already widely used in the market).

[0037] Working principle:

[0038] Water overflowing from the rim of the cup body 1 is collected by the drainage ring 8 and flows through the spacer and arc-shaped water guide groove 9 before entering the annular mounting groove 17, where it is absorbed by the annular water-absorbing block 20. This prevents hot water inside the cup body 1 from overflowing due to the pressure of the lid 2 and scalding the user's hands, and also prevents water from dripping from the bottom of the thermos onto the table, floor, or the user's clothing.

[0039] When the annular absorbent block 20 needs to be replaced or dried, the user inserts their finger into the gap and uses the lever 24 to move the annular cover plate 21 to remove it, thus taking the annular absorbent block 20 out of the annular mounting groove 17. After the annular absorbent block 20 is installed in the annular mounting groove 17, when the annular cover plate 21 is placed over the opening of the annular mounting groove 17, because the entire flow guiding component is made of plastic material, which has a certain degree of elasticity, the cover plate can be smoothly inserted into the annular mounting groove 17, and the annular protrusion 19 will insert into the annular retaining groove 22, thereby fixing the annular cover plate 21.

[0040] When the flow guide assembly needs to be disassembled, the user presses the two pressing rods 15 with two fingers, thereby moving the two sliding rods 13 towards each other along the cavity wall of the inner cavity 12. The spring 14 is compressed, creating a rebound force towards the outside of the inner cavity 12. The sliding rods 13 move the locking rod 16 into the cavity. When the end of the locking rod 16 that was originally inserted into the locking hole 4 is completely pulled out of the locking hole 4, the connecting rod 11 can be pulled out from the connecting groove 3, thereby removing the flow guide assembly from the cup body 1. Similarly, when the flow guide assembly needs to be installed, first press the pressing rod 15, then align the insert 25 and insert it into the slot 5. At the same time, the connecting rod 11 will also be inserted into the connecting groove 3. With the positioning of the insert 25 and the slot 5, when the connecting rod 11 is inserted into the connecting groove 3, the locking rod 16 corresponds to the locking hole 4. Next, release the pressing lever 15. Under the rebound force of the spring 14, one end of the locking lever 16 is inserted into the locking hole 4, thereby installing the flow guide assembly on the outside of the cup body 1.
