[0024] Please refer to Figures 1 to 4For the embodiment of the utility model discloses a plastic bottle with heating function, including bottle body 10, bottle cap 20, bottle body 10 sets outer thread 110, bottle cap 20 sets up the inner thread 21 of cooperation with outer thread 110, bottle cap 20 includes the connecting section 22 of bottle body 10 screw connection and set up on the cover section 23 of connecting section 22, cover section 23 and connecting section 22 one end pivot connection, the other end to buckling joint;Connecting section 22 towards the bottle spout 24 of cover section 23 one side outwardly protrude, set up the water outlet 240 on bottle spout 24;Bottle body 10 includes the shell 11 of bottle cap 20 screw connection and the inner container 12 of the sleeve of shell 11, shell 11 and inner container 12 top closed connection, inner container 12 includes first inner bottle 120 and the second inner bottle 121 of the sleeve of first inner bottle 120, first inner bottle 120 and second inner bottle 121 top closed connection, heating piece 30 sets up on first inner bottle 120.In this embodiment, shell 11 is plastic material.

[0025] The working principle of the plastic bottle with heating function of the utility model is as follows: when the liquid in the bottle needs to be heated, the heating piece 30 at the bottom of the first inner bottle 120 is started; after the heating piece 30 works, the heat generated will be transferred to the liquid in the first inner bottle 120; since the second inner bottle 121 is sleeved in the first inner bottle 120, the space between the first inner bottle 120 and the second inner bottle 121 will also be heated; the heat is transferred in the liquid in the form of heat conduction, so that the temperature of the liquid is raised; the bottle cap 20 is screw-connected with the bottle body 10 through the inner thread 21 of the connecting section 22 and the outer thread 110 of the bottle body 10, so as to ensure the sealing property of the bottle body 10; when the liquid needs to be poured out, the cover section 23 and the connecting section 22 buckled are opened, and the liquid can flow out from the water outlet 240 of the bottle spout 24.

[0026] Compared with the prior art, the plastic bottle with heating function of the utility model, the heating piece 30 in the bottle is arranged at the bottom of the first inner bottle 120, which can quickly heat the liquid in the second inner bottle 121; compared with using external heating equipment, this direct heating method in the bottle can avoid the loss of heat in the transfer process and more efficiently raise the temperature of the liquid; during the heating process, the multi-layer structure of the bottle body 10 also helps to reduce the heat dissipation to the outside world, so that the heat is concentrated in the liquid in the bottle as much as possible, and the heating efficiency is improved; this plastic bottle with heating function allows users to conveniently drink hot drinks when going out. For example, in cold winter, people can take hot water, hot coffee or hot tea out, whether they are working, exercising or traveling outdoors, as long as they need, they can start the heating function and enjoy warm drinks at any time.

[0027] Please refer to Figures 2 to 4The plastic bottle with heating function further comprises a first fixed shaft 40 arranged on one side of the cover segment 23 and a shaft sleeve 50 arranged on one side of the connecting segment 22 and matched with the first fixed shaft 40. The shaft sleeve 50 is sleeved on the first fixed shaft 40, and the cover segment 23 and the connecting segment 22 are connected by the first fixed shaft 40 and the shaft sleeve 50. When the user needs to open the bottle cap 20 to take out the liquid in the bottle or check the situation in the bottle, the user holds the cover segment 23 and rotates it around the first fixed shaft 40. Because the shaft sleeve 50 is sleeved on the first fixed shaft 40, the structure is similar to a simple hinge, so that the cover segment 23 can rotate smoothly relative to the connecting segment 22. The matching between the first fixed shaft 40 and the shaft sleeve 50 provides a stable rotation fulcrum. During rotation, the shaft sleeve 50 rotates around the first fixed shaft 40, ensuring the smoothness of the cover segment 23 during opening and closing, and enabling the user to accurately control the opening and closing angle of the cover segment 23. For example, the user can rotate the cover segment 23 by 90 degrees or 180 degrees to completely open the bottle cap 20, facilitating pouring out of the liquid or other operations. This shaft connection mode also has certain mechanical stability. When the bottle cap 20 is subjected to external force, such as shaking of the bottle body during carrying or accidental collision, the first fixed shaft 40 and the shaft sleeve 50 can withstand a certain impact force, reducing the possibility of damage between the cover segment 23 and the connecting segment 22 due to external force, thereby maintaining the integrity and sealing of the bottle cap 20 structure.

[0028] The plastic bottle with heating function further comprises a torsional spring 60 sleeved on the first fixed shaft 40, one end of the torsional spring 60 abutting against the connecting segment 22, and the other end abutting against the cover segment 23. The torsional spring 60 is sleeved on the first fixed shaft 40, and the two ends abut against the connecting segment 22 and the cover segment 23, respectively. When the bottle cap 20 is opened, that is, the cover segment 23 is rotated relative to the connecting segment 22 around the first fixed shaft 40, the torsional spring 60 will be elastically deformed. After the user releases the cover segment 23, the cover segment 23 will automatically rotate in the closing direction under the action of the restoring force of the torsional spring 60, thereby realizing the automatic reset function. This enables the bottle cap 20 to be conveniently automatically closed after being opened, which can effectively prevent dust, impurities and the like from easily entering the bottle. During closing of the bottle cap 20, the elastic potential energy of the torsional spring 60 also plays a boosting role. Even if the bottle cap 20 is only slightly pushed to rotate in the closing direction, the torsional spring 60 will release the elastic potential energy to help the cover segment 23 close the connecting segment 22 more quickly. This makes the operation of closing the bottle cap 20 more effortless, especially when the user has liquid or something slippery on his hands. The torsional spring 60 can assist in tightly closing the bottle cap 20, ensuring the sealing of the bottle.

[0029] The fixed buckle 25 is arranged on the cover segment 23 away from the first fixed shaft 40, and the movable assembly 26 is arranged on the connecting segment 22 away from the shaft sleeve 50 and cooperates with the fixed buckle. The movable assembly 26 includes a first elastic member 260 extending outward from one side of the connecting segment 22 and a movable buckle 261 connected to the free end of the first elastic member 260. The fixed buckle 25 cooperates with the movable buckle 261. In this embodiment, the first elastic member 260 is a spring. When the cover segment 23 rotates around the first fixed shaft 40 and closes the connecting segment 22, the fixed buckle 25 on the cover segment 23 gradually approaches the movable assembly 26 on the connecting segment 22. When the two are in contact, the fixed buckle 25 exerts pressure on the movable buckle 261. The first elastic member 260 in the movable assembly 26 has elasticity. Under the pressure of the fixed buckle 25, the movable buckle 261 compresses the first elastic member 260, so that the movable buckle 261 retreats. As the cover segment 23 continues to rotate, when the fixed buckle 25 passes the retreat position of the movable buckle 261, the first elastic member 260 restores the elastic deformation and pushes the movable buckle 261 back to the original position. At this time, the fixed buckle 25 and the movable buckle 261 cooperate with each other to tightly buckle the cover segment 23 and the connecting segment 22 together. This buckling structure can ensure that the bottle cap 20 maintains good sealing in the closed state, preventing the liquid in the bottle from leaking or external air, impurities, etc. from entering the bottle. When it is necessary to open the bottle cap 20, the user needs to exert a certain external force to overcome the buckling force between the fixed buckle 25 and the movable buckle 261. By pressing the movable buckle 261, the first elastic member 260 is compressed again, and the movable buckle 261 moves away from the locking position of the fixed buckle 25. At this time, the cover segment 23 can be rotated around the first fixed shaft 40 to be opened, thereby facilitating the user to use the liquid in the bottle or to perform other operations on the bottle, such as cleaning, adding items, etc.

[0030] The movable assembly further comprises a fixed support extending outward from the periphery of the first elastic member 260 on one side of the connecting segment 22 and a second fixed shaft 262 mounted on the fixed support, and the movable buckle 261 is sleeved on the second fixed shaft 262, and the first elastic member 260 is arranged on the top of the second fixed shaft 262. The movable buckle 261 is sleeved on the second fixed shaft 262, and when the fixed buckle 25 interacts with the movable buckle 261, the second fixed shaft 262 provides a precise movement track for the movable buckle 261; for example, when the closing segment 23 is closed, the fixed buckle 25 extrudes the movable buckle 261, and the movable buckle 261 can only perform a compression movement along the axial direction of the second fixed shaft 262, so that the movement direction of the movable buckle 261 is stable and predictable. The second fixed shaft 262 limits the displacement of the movable buckle 261 in other directions, prevents the movable buckle 261 from unnecessary shaking or deviating from the correct movement path when subjected to external force, helps to keep the accurate cooperation between the movable buckle 261 and the fixed buckle 25, and thus guarantees the sealing performance of the bottle cap 20 when closed. The first elastic member 260 is arranged on the top of the second fixed shaft 262, and the fixed support 31 extends around the periphery of the first elastic member 260, which provides a stable mounting position for the first elastic member 260; the first elastic member 260 can be prevented from deviating or falling off during the compression and recovery process of the movable buckle 261; when the fixed buckle 25 extrudes the movable buckle 261, the movable buckle 261 compresses the first elastic member 260 downward along the second fixed shaft 262; at this time, the first elastic member 260 is compressed and deformed, and converts the mechanical energy applied from outside into elastic potential energy and stores it; when the external force disappears, the first elastic member 260 releases the elastic potential energy and pushes the movable buckle 261 to recover to the original position upward along the second fixed shaft 262, so as to realize the buckling with the fixed buckle 25; the storage and release process of the elastic potential energy ensures the reliable buckling and convenient opening of the bottle cap 20.

[0031] The two sides of the movable buckle 261 at the bottom of the second fixed shaft 262 are provided with sliding grooves 261A, and the movable assembly further includes a locking sliding block 263 slidingly arranged in the sliding grooves 261A; when the locking sliding block 263 slides away from the second fixed shaft 262, the free end of the locking sliding block 263 abuts against the fixed support; when the locking sliding block 263 slides close to the second fixed shaft 262, the free end of the locking sliding block 263 is disengaged from the limiting of the fixed support. When the locking sliding block 263 slides away from the second fixed shaft 262, the free end thereof abuts against the fixed support; in this state, the fixed support limits the locking sliding block 263, preventing the locking sliding block 263 from continuously sliding outward; since the locking sliding block 263 is located in the sliding grooves 261A on the two sides of the movable buckle 261, the locking sliding block 263 transversely limits the movable buckle 261 at this time; when the movable buckle 261 is squeezed by the fixed buckle 25 and attempts to move transversely, the movable buckle 261 is blocked by the locking sliding block 263; in this way, the stability of the movable buckle 261 on the second fixed shaft 262 is enhanced, ensuring that the movable buckle 261 can only perform compression movement along the axial direction of the second fixed shaft 262, thereby ensuring the reliability of the movable assembly of the bottle cap 20 in the normal use process; when it is necessary to open the bottle cap 20, the locking sliding block 263 is slid toward the second fixed shaft 262; as the free end of the locking sliding block 263 is disengaged from the limiting of the fixed support, the transverse limiting effect of the locking sliding block 263 on the movable buckle 261 is weakened; at this time, the user can more easily press the movable buckle 261, so that the movable buckle 261 can perform compression movement along the axial direction of the second fixed shaft 262, thereby releasing the buckling between the fixed buckle 25 and the movable buckle 261; in this way, the closure section 23 can be opened, facilitating the user to take out the liquid in the bottle or to perform other operations; the controllability of the opening of the bottle cap 20 is improved, and the movement range of the movable buckle 261 can be controlled through the position of the locking sliding block 263, further improving the safety and practicality of the movable assembly of the bottle cap 20.

[0032] Please refer to Figure 2 The heating element 30 includes a fixed support 31 mounted at the bottom of the first inner bottle 120 and a heating wire 32 mounted on the fixed support 31. The heating wire 32 is mounted on the fixed support 31 at the bottom of the first inner bottle 120, and the fixed support 31 stabilizes the position of the heating wire 32; it can ensure that the heating wire 32 is maintained at a suitable position in the bottle, avoiding displacement of the heating wire 32 in the daily use process of the bottle (such as being shaken, tilted, etc.). The generated heat is transferred to the liquid in the second inner bottle 121 in the form of heat conduction; since the liquid has good heat conductivity, the heat will gradually spread in the liquid; thereby the liquid in the entire bottle can be uniformly heated.

[0033] The plastic bottle with heating function further comprises a second elastic member 70 arranged between the outer wall of the second inner bottle 121 and the inner wall of the first inner bottle 120. In the embodiment, the second elastic member 70 is rubber and a spring wrapped outside the rubber. When the bottle is subjected to external impact force, for example, accidentally falling or being hit, the second elastic member 70 can play a buffering role. Because the elastic member can elastically deform when subjected to force, it can absorb and disperse part of the impact force; assuming that the bottle falls from a certain height, the impact force will be transmitted to the bottle body 10 at the moment of landing; at this time, the second elastic member 70 will be extruded and deformed, converting the impact force into elastic potential energy and storing it, rather than allowing the impact force to act directly on the inner container 12, thereby reducing the risk of breaking the inner container 12; for example, if there is no second elastic member 70, the first inner bottle 120 and the second inner bottle 121 may be damaged due to the violent impact, causing liquid leakage; with the second elastic member 70, the integrity of the inner container 12 can be protected to some extent. During heating, the thermal expansion of the inner container 12 will be caused by the temperature rise of the liquid in the bottle; the second elastic member 70 can provide space compensation for the thermal expansion of the inner container 12; as the temperature of the liquid rises, the first inner bottle 120 and the second inner bottle 121 expand due to heat, and the second elastic member 70 is compressed, and the space originally occupied by the second elastic member 70 can provide a margin for the expansion of the inner container 12.

[0034] Please refer to Figures 2 to 4 The bottle cap 20 opposite to the water outlet 240 is provided with a bottle plug 27 opposite to the water outlet 240. When the bottle does not need to pour out liquid, the bottle plug 27 can be plugged into the water outlet 240, thereby playing a sealing role; the contact between the bottle plug 27 and the water outlet 240 is a kind of close intermolecular interaction; when the bottle plug 27 is plugged in, the distance between the molecules on the surface of the bottle plug 27 and the molecules on the inner wall of the water outlet 240 is close enough to generate van der Waals force, which forms a seal between the bottle plug 27 and the water outlet 240, preventing the liquid in the bottle from leaking, and also preventing external air, dust and impurities from entering the bottle.

[0035] The connecting section 22 opposite to the cover section 23 is provided with a rubber ring 28 for buffering. The presence of the rubber ring 28 can enhance the sealing performance of the bottle cap 20. When the cover section 23 and the connecting section 22 are tightly attached, the rubber ring 28 is extruded and deformed, filling the possible small gap between the cover section 23 and the connecting section 22; when the cover section 23 is closed, it will contact the rubber ring 28 on the connecting section 22; the rubber ring 28 has good elasticity; during the closing process of the bottle cap 20, if the force is large or the bottle is shaken, collided or the like, the rubber ring 28 can play a buffering role.

[0036] The above merely expresses the preferred technical solutions of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, and the present application also intends to include these changes and modifications.
