Description

Technical Field

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

[0002] Among existing patents, Chinese patent application number 201920599930.1 discloses a cup body, a cup holder, and a portable smart water cup. The portable smart water cup includes a cup body and a cup holder. The cup body includes a heating element, a temperature detector, and a conductive ring, as well as an inner liner and an outer shell with an opening. The inner liner is disposed within the outer shell and is used to contain liquid. The heating element and the conductive ring are installed on the side of the inner liner away from the opening, and the conductive ring is electrically connected to the heating element and the temperature detector. The conductive ring is used to supply power to the heating element when a power source is connected, and to transmit the detection signal fed back by the temperature detector. The cup body and the cup holder are detachably connected.

[0003] Furthermore, Chinese patent application number 202421435777.6 discloses a detachable portable thermos cup, including a thermos cup body, a lid connected to the thermos cup body, and a base connected to the bottom of the thermos cup body. The thermos cup body and the base are detachably connected by a screw-on structure. The base is provided with a rechargeable power module, a control module, and elastically retractable electrode pins. The control module is connected to both the power module and the electrode pins. The electrode pins are located at the top of the base. The bottom of the thermos cup body is provided with a connector that can be electrically coupled to the electrode pins. The thermos cup body is provided with a heating element for heating and a temperature sensor for detection. The heating element and the temperature sensor are electrically connected to the connector.

[0004] Although both patent documents disclose that the base and the cup body can be detached and that a snap-lock detachable structure is provided, the assembly and disassembly of the base and the cup body are relatively easy. That is, when the base and the cup body are rotated in the forward direction, they are assembled; when the base and the cup body are rotated in the reverse direction, they are separated. This makes it easy for the base and the cup body to separate unintentionally. As a result, the assembly of the base and the cup body is relatively weak and prone to problems such as improper assembly.

[0005] Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

[0006] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a temperature-controlled cup.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A temperature-controlled cup includes a cup body, an inner cup, a middle ring, a locking ring, a sealing ring, a base, and a temperature control module disposed within the base. The inner cup is disposed within the cup body. The outer wall of the middle ring is welded to the bottom inner wall of the cup body, and the middle ring is located below the inner cup. The locking ring is disposed on the top inner wall of the middle ring. The outer wall of the base port is fitted with a sealing ring, and the base port is inserted into the middle ring. The sealing ring is sandwiched between the base port and the inner wall of the middle ring. The inner ring of the locking ring has multiple buckles arranged in a circular array. The base port has multiple slot structures arranged in a circular array. The multiple buckles are used to engage with the multiple slot structures respectively. The inner ring of the locking ring also has a limiting spring. The base port has a limiting position. The limiting spring can enter into the limiting position and be locked in the limiting position. The buckles can be screwed into the slot structure in one direction. The temperature control module is used to control the temperature of the liquid contained in the inner cup.

[0008] Furthermore, the buckle is L-shaped and extends downward from the inner ring of the locking ring. The slot structure includes a limiting block integrally formed on the inner wall of the port of the base, a vertical plate integrally formed on the inner wall of the port of the base, and a blocking block set at the top of the vertical plate. When the cup body rotates unidirectionally relative to the base, the vertical plate and the limiting block are arranged sequentially along the rotation direction, and the buckle and the limiting spring are arranged sequentially along the rotation direction. A screw-in slot is formed between the limiting block, the vertical plate, and the blocking block for the buckle to screw into. When the buckle engages with the screw-in slot, the vertical part of the buckle abuts against one side of the limiting block, the horizontal part of the buckle is above the top surface of the vertical plate, the horizontal part of the buckle is below the limiting block, and the inner wall of the blocking block abuts against the side of the buckle.

[0009] Furthermore, the limiting spring includes an elastic plate that extends downward from the inner ring of the self-locking ring and a guide plate formed by bending the bottom of the elastic plate.

[0010] Furthermore, a guide slope is provided on one side of the limiting position, which is used to slide against the guide plate.

[0011] Furthermore, the limiting position includes two limiting plates disposed on the inner wall of the port of the base. The two limiting plates are spaced a certain distance apart and are arranged in parallel. A limiting groove is formed between the two limiting plates. The limiting spring can be locked in the limiting groove. A guide slope is provided on the top of the limiting plate located on the screw-in side of the limiting groove.

[0012] Furthermore, the bottom surface of the base is recessed with multiple disassembly slots in a circular array.

[0013] Furthermore, the bottom surface of the base is recessed with an annular groove, and the disassembly slot is recessed from the bottom wall of the annular groove.

[0014] Furthermore, an anti-slip pad is embedded in the annular groove.

[0015] Furthermore, the temperature-controlled cup also includes a lid that is removably attached to the top port of the cup body and / or the top port of the inner cup.

[0016] Furthermore, the top surface of the cup lid is recessed with a liquid storage cavity, the bottom wall of the liquid storage cavity is provided with a liquid outlet hole, and the top surface of the cup lid is provided with a pressure relief hole, which is located on one side of the liquid storage cavity.

[0017] The beneficial effects of this utility model are as follows: In practical applications, during assembly, the inner cup is installed or formed inside the cup body, the locking ring is welded and fixed to the inner wall of the middle ring, the middle ring is welded to the bottom inner wall of the cup body, the temperature control module is installed inside the base, and the sealing ring is fitted onto the outer wall of the port of the base. Then, the port of the base fitted with the sealing ring is inserted into the middle ring inside the cup body. At this time, multiple buckles are misaligned with multiple slot structures. Then, the cup body and the base are driven to rotate relative to each other according to the preset rotation direction, so that each buckle rotates toward the corresponding slot structure until the buckle is screwed into the slot structure, so that the buckle and the slot structure are engaged. During this process, the limiting spring rotates toward the limiting position. When the limiting spring abuts against the limiting position, the limiting spring will undergo a recoverable elastic deformation until the limiting spring rotates into the limiting position. The limiting spring then recovers its elasticity, so that the limiting spring is locked in the limiting position, ensuring that the cup body and the base can be firmly assembled together and the cup body and the base will not easily separate. Furthermore, during the elastic deformation and recovery process of the limiting spring, it will produce a tactile sensation or a sound. When the operator feels the sensation or hears the sound, it indicates that the cup body and base are properly assembled. This avoids both over-assembly and under-assembly. In actual use, the inner cup is filled with liquid, and the temperature control module heats and maintains the temperature of the liquid inside the inner cup. Of course, a mobile terminal (such as a mobile phone) connects to the temperature control module via a smart APP to control the module's usage status and thus control the temperature of the liquid inside the inner cup. This invention, through the cooperation of the limiting spring and the limiting latch, as well as the cooperation of the buckle and the slot structure, ensures that the cup body and base are properly assembled, allowing for quick and secure assembly and preventing disassembly.

[0025] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0026] like Figures 1 to 6 As shown, this utility model provides a temperature-controlled cup, which includes a cup body 1, an inner cup 2, a middle ring 3, a locking ring 4, a sealing ring 5, a base 6, and a temperature control module 7 disposed within the base 6. The inner cup 2 is disposed within the cup body 1. The outer wall of the middle ring 3 is welded to the bottom inner wall of the cup body 1, and the middle ring 3 is located below the inner cup 2. The locking ring 4 is disposed on the top inner wall of the middle ring 3. The sealing ring 5 is fitted onto the outer wall of the port of the base 6. The port of the base 6 is inserted into the middle ring 3, and the sealing ring 5 is sandwiched between the port of the base 6 and the inner wall of the middle ring 3. The inner ring of the locking ring 4 has multiple buckles 8 arranged in a circular array, and the port of the base 6 has multiple slot structures 9 arranged in a circular array. The multiple buckles 8 are used to engage with the multiple slot structures 9 respectively. The inner ring of the locking ring 4 also has a limiting spring 10, and the port of the base 6 has a limiting position 11. The limiting spring 10 can enter into the limiting position 11 and be locked in the limiting position 11. The buckles 8 can be screwed into the slot structure 9 in one direction. The temperature control module 7 is used to control the temperature of the liquid loaded in the inner cup 2. Specifically, the locking ring 4 is welded to the top inner wall of the middle ring 3; there is a gap 30 between the outer wall of the inner cup 2 and the inner wall of the cup body 1.

[0027] In practical applications, during assembly, the inner cup 2 is installed or formed inside the cup body 1, the locking ring 4 is welded and fixed to the inner wall of the middle ring 3, the middle ring 3 is welded to the bottom inner wall of the cup body 1, the temperature control module 7 is installed inside the base 6, and the sealing ring 5 is fitted onto the outer wall of the port of the base 6. Then, the port of the base 6 with the sealing ring 5 is inserted into the middle ring 3 inside the cup body 1. At this time, multiple buckles 8 are misaligned with multiple slot structures 9. Then, the cup body 1 and the base 6 are driven to rotate relative to each other according to the preset rotation direction, so that each buckle 8 faces the corresponding slot structure. The mechanism 9 rotates until the buckle 8 is screwed into the slot structure 9, making the buckle 8 and the slot structure 9 engage. During this process, the limiting spring 10 rotates toward the limiting slot 11. When the limiting spring 10 abuts against the limiting slot 11, the limiting spring 10 will undergo a recoverable elastic deformation until it rotates into the limiting slot 11. Then, the limiting spring 10 elastically recovers, so that the limiting spring 10 is locked in the limiting slot 11, ensuring that the cup body 1 and the base 6 can be firmly assembled together and will not easily separate. In addition, during the process of the limiting spring 10 undergoing elastic deformation and recovering its elasticity, the limiting spring 10 will produce a tactile sensation or a sound. When the operator feels the sensation or hears the sound, it proves that the cup body 1 and the base 6 are assembled in place, which can avoid the problems of over-assembly and under-assembly. In actual use, the inner cup 2 is filled with liquid, and the temperature control module 7 heats and maintains the temperature of the liquid in the inner cup 2. Of course, mobile terminals (such as mobile phones) connect to the temperature control module 7 via a smart APP to control the usage status of the temperature control module 7, thereby controlling the temperature of the liquid inside the inner cup 2. This invention, through the cooperation of the limiting spring 10 and the limiting latch 11, and the cooperation of the buckle 8 and the slot structure 9, ensures that the cup body 1 and the base 6 are assembled in place, allowing for quick and secure assembly of the cup body 1 and the base 6, and preventing them from easily disassembling.

[0028] In this embodiment, the buckle 8 is L-shaped and extends downward from the inner ring of the locking ring 4. The slot structure 9 includes a limiting block 12 integrally formed on the inner wall of the port of the base 6, a vertical plate 13 integrally formed on the inner wall of the port of the base 6, and a blocking block 14 set at the top of the vertical plate 13. When the cup body 1 rotates unidirectionally relative to the base 6, the vertical plate 13 and the limiting block 12 are arranged sequentially along the rotation direction, and the buckle 8 and the limiting spring piece 10 are arranged sequentially along the rotation direction. A screw-in slot 15 is formed between the limiting block 12, the vertical plate 13, and the blocking block 14 for the buckle 8 to screw into. When the buckle 8 engages with the screw-in slot 15, the vertical part of the buckle 8 abuts against one side of the limiting block 12, the horizontal part of the buckle 8 is above the top surface of the vertical plate 13, the horizontal part of the buckle 8 is below the limiting block 12, and the inner wall of the blocking block 14 abuts against the side of the buckle 8. The design of the buckle 8 and the slot structure 9 facilitates the buckle 8 and the slot structure 9 to engage and cooperate, and the slot structure 9 will not interfere with the limiting spring 10 being screwed into the limiting slot 11.

[0029] Specifically, both the locking ring 4 and the limiting spring 10 are made of semi-hard spring steel, which has good resilience.

[0030] In this embodiment, the limiting spring 10 includes an elastic plate 16 that extends downward from the inner ring of the self-locking ring 4 and a guide plate 17 formed by bending from the bottom of the elastic plate 16. During the process of the limiting spring 10 being screwed into the limiting slot 11, the guide plate 17 abuts against one side of the limiting slot 11, which facilitates the elastic deformation of the limiting spring 10 and allows it to move smoothly into the limiting slot 11. After the limiting spring 10 moves into the limiting slot 11, the limiting spring 10 elastically recovers and is locked in the limiting slot 11.

[0031] In this embodiment, a guide slope 18 is provided on one side of the limiting position 11, which is used to slide against the guide slope plate 17. Specifically, the limiting position 11 includes two limiting plates 19 disposed on the inner wall of the port of the base 6. The two limiting plates 19 are spaced a certain distance apart and arranged in parallel, forming a limiting groove 20 between the two limiting plates 19. The limiting spring piece 10 can be locked in the limiting groove 20. The top of the limiting plate 19 located on the screw-in side of the limiting groove 20 is provided with a guide slope 18. During the process of the limiting spring piece 10 being screwed into the limiting position 11, the contact between the guide slope 18 and the guide slope plate 17 facilitates the elastic deformation of the limiting spring piece 10, thereby facilitating the smooth movement of the limiting spring piece 10 into the limiting position 11.

[0032] In this embodiment, the bottom surface of the base 6 is provided with a plurality of disassembly slots 21 arranged in a ring array. When it is necessary to separate the cup body 1 and the base 6, the multiple claws of the disassembly tool are inserted into the multiple disassembly slots 21 respectively, driving the disassembly tool to rotate in the opposite direction so as to drive the base 6 to rotate in the opposite direction relative to the cup body 1 (the direction of the reverse rotation is opposite to the direction of rotation during assembly). Since the force of this reverse rotation is large, the limiting spring 10 will undergo elastic deformation and move out of the limiting slot 11, thereby causing the buckle 8 to move out of the slot structure 9, thus realizing the separation / disassembly of the cup body 1 and the base 6.

[0033] In this embodiment, the bottom surface of the base 6 is recessed with an annular groove 22, and the disassembly slot 21 is recessed from the bottom wall of the annular groove 22; specifically, an anti-slip pad 23 is embedded in the annular groove 22. The anti-slip pad 23 not only covers the disassembly slot 21 and is aesthetically pleasing, but also plays a role in preventing slippage.

[0034] In this embodiment, the temperature-controlled cup also includes a cup lid 24 that is detachably disposed on the top port of the cup body 1 and / or the top port of the inner cup 2.

[0035] In this embodiment, the top surface of the cup lid 24 is recessed with a liquid storage cavity 25, and the bottom wall of the liquid storage cavity 25 is provided with a liquid outlet 26. The top surface of the cup lid 24 is provided with a pressure relief hole 27, which is located on one side of the liquid storage cavity 25. In practical applications, the pressure relief hole 27 serves to relieve pressure. When it is necessary to drink the liquid in the inner cup 2, the temperature-controlled cup is tilted so that the liquid in the inner cup 2 flows from the liquid outlet 26 into the liquid storage cavity 25. If the poured liquid is too hot to drink directly, it can be drunk after the liquid in the liquid storage cavity 25 has cooled down to a suitable temperature. The liquid storage cavity 25 temporarily stores the liquid, which is beneficial for quickly cooling the liquid before drinking.

[0036] Specifically, the top edge of the cup lid 24 is provided with a lifting protrusion 28. The lifting protrusion 28 makes it easy for the operator to open the cup lid 24.

[0037] Specifically, a sealing ring 29 is fitted onto the bottom outer wall of the cup lid 24. The sealing ring 29 is used to seal the gap 30 between the cup lid 24 and the inner wall of the inner cup 2. This structural design reduces the contact area between the inner cup 2 and the cup body 1, reduces the rate at which heat is transferred outward from the inner cup 2, thereby reducing heat loss and improving the heat preservation effect.

[0038] Specifically, the temperature control module 7 includes a circuit board 31, a battery pack 32, a processor 33, a heating element 34, and a switch button 35. The circuit board 31 is installed inside the base 6. The heating element 34, battery pack 32, processor 33, and switch button 35 are all electrically connected to the circuit board 31. The heating element 34 is used to heat the inner cup 2. The switch button 35 is movably embedded in the base 6 and exposed on the outer wall of the base 6. The switch button 35 is used to control the heating element 34 to start or stop heating.

[0039] Specifically, the temperature control module 7 also includes a locking plate 36, which is used to lock the battery pack 32 onto the base 6 or the circuit board 31. This structural design improves the stability of the assembled battery pack 32.

[0040] Specifically, the temperature control module 7 also includes a speaker 37 electrically connected to the circuit board 31. Multiple sound outlets are provided on the side wall of the base 6, and the speaker 37 is correspondingly positioned to each sound outlet. During operation, the speaker 37 can emit voice announcements to serve as reminders, allowing the operator to know whether the operation is effective or correct. The sound outlets not only facilitate the propagation of the voice announcements but also aid in heat dissipation.

[0041] Specifically, the inner sidewall of the base 6 is provided with four limiting guide grooves 38, which are arranged in a rectangular shape. The four corners of the battery pack 32 are confined within the four limiting guide grooves 38. Preferably, the battery pack 32 is a lithium battery. During assembly, the battery pack 32 is inserted into the four limiting guide grooves 38 from top to bottom. The four limiting guide grooves 38 position and assemble the battery pack 32, improving the assembly position accuracy and assembly firmness of the battery pack 32.

[0042] Specifically, the heating element 34 is a thin-film ceramic heating element, which is attached to or embedded in the bottom outer surface of the inner cup 2. This structural design helps to improve the heating effect of the inner cup 2.

[0043] Specifically, the temperature control module 7 also includes a reset switch 39 electrically connected to the circuit board 31, and a reset button 40 is provided on the inner wall of the bottom surface of the base 6. The reset button 40 is corresponding to the reset switch 39 and is used to trigger the reset switch 39. In practical applications, simply pressing the bottom of the base 6 and causing the reset button 40 to press the reset switch 39 can achieve one-click restoration to the original factory state.

[0044] All technical features in this embodiment can be freely combined according to actual needs.

[0045] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
