Description

Technical Field

[0001] This utility model relates to the field of sealed container technology, specifically a mechanical and electronically controlled sealing structure for thermos cups. Background Technology

[0002] Most commonly found sealed cups on the market, such as insulated cups, rely on screw-top lids for sealing. By rotating the lid, a sealing ring fixed inside the lid is pressed against the top of the cup opening or the outer wall, thus forming a seal. This traditional method has several inherent drawbacks: First, the screw-on operation is cumbersome, making quick one-button opening and closing impossible; second, the seal is located at the top of the cup opening, which, for scenarios requiring optimal insulation, results in a shorter heat exchange path and less room for improvement in insulation performance; third, the screw-top structure occupies a large portion of the lid's internal space, leading to limited space. If intelligent functions such as electronic lid opening and status display are to be integrated, there is virtually no room to install components such as a motor, battery, and display panel.

[0003] A search revealed Chinese patent CN211748581U, which discloses a composite metal ring for manufacturing titanium thermos cups and the titanium thermos cup itself. The composite metal ring includes a titanium ring for welding to the titanium inner liner of the thermos cup and a stainless steel ring for welding to the stainless steel outer shell of the thermos cup. The titanium ring and stainless steel ring are joined by a stop structure, and the joint of the stop structure is sealed and fixed by brazing. In titanium thermos cups using the composite metal ring, a vacuum layer is provided between the titanium inner liner and the stainless steel outer shell. This invention can save valuable titanium material, improve the quality of titanium thermos cups, simplify processing, increase production efficiency, further reduce costs, and is suitable for mass production. However, existing technologies cannot achieve one-click quick opening and closing and intelligent electronic control operation of thermos cup lids, resulting in a poor user experience. At the same time, the traditional top sealing method has a short heat exchange path, which limits further improvement in heat preservation performance. In addition, the internal space of the cup lid is largely occupied by the threaded structure, resulting in a complex structure and cramped internal space, making it difficult to integrate components such as motors and batteries, thus hindering the intelligent development of thermos cups.

[0004] Therefore, based on the above search and combined with existing technology, a mechanical and electronically controlled sealing structure for thermos cups is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a mechanical and electronically controlled sealing structure for thermos cups to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A mechanically and electrically controlled sealing structure for a thermos cup includes: a cup body having an inner opening, a cup lid being provided on the top surface of the cup body, an installation groove being formed on the top surface of the cup lid, a sealing element being fixedly installed on the inner wall of the installation groove, the sealing element being located in the inner opening of the cup body, a sliding groove being formed on the top surface of the sealing element, a pressing element being slidably installed in the sliding groove, and a sealing coupling element being fixedly installed on the bottom surface of the pressing element.

[0007] Preferably, the sidewall of the slide groove is provided with a first intersection point and a second intersection point from top to bottom, and the sidewall of the pressing member is provided with concave and convex points, which cooperate with the first intersection point and the second intersection point.

[0008] Preferably, when the user presses the pressing member, the pressing member moves downward, causing the concave and convex points on the side wall of the pressing member to compress and deform the intersection of the first intersection point and the second intersection point of the slide groove side wall. This causes the first intersection point to expand and compress to seal, while the second intersection point expands and compresses outward, causing the outer wall of the sealing member to fit against the inner wall of the cup's inner opening, thus achieving a sealing effect.

[0009] Preferably, the lower part of the inner opening of the cup is an inwardly tapering slope.

[0010] Preferably, the sealing element is made of food-grade silicone or food-grade sealing rubber.

[0011] Preferably, the pressing element and the sealing element are made of stainless steel, high borosilicate glass, or other food-grade hard materials.

[0012] Preferably, the upper part of the pressing member is configured as a manually operated button.

[0013] Preferably, the pressing element is connected to an electronically controlled drive device, which includes a motor, a transmission mechanism that converts the rotational motion of the motor into linear motion, a battery that supplies power to the motor, and a control module for receiving control commands and driving the motor to rotate forward or in reverse.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a cup lid, mounting groove, sealing element, sliding groove, pressing element, and sealing coupling element. By leveraging the interlocking points of the pressing element's sidewall and the first and second intersection points of the sealing element's sliding groove sidewall, a single pressing or pulling action drives the sealing element to undergo controlled deformation in stages and regions, ensuring a tight fit between its outer wall and the inner wall of the cup's inner opening along its entire length. This not only achieves one-button quick opening and closing, making operation extremely convenient, but also effectively extends the heat exchange path through full-length sidewall sealing, significantly improving the cup's heat preservation performance. This structure replaces the traditional threaded rotary sealing method, saving considerable space inside the cup lid.

[0015] This invention combines a pressing component with an electronically controlled drive device. The motor, transmission mechanism, battery, and control module drive the pressing component in linear motion, achieving automation and intelligence in the sealing and opening of the cup lid. Users can control it via physical buttons, touch, or wireless signals, greatly enhancing the user experience. Furthermore, this invention eliminates the complex threaded structure, freeing up internal space in the cup lid for integrating electronic control components, making the smart thermos cup compact, cost-effective, and reliable in operation.

[0018] 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.

[0019] In one typical embodiment of this application, please refer to Figures 1-4As shown, a mechanically and electrically controlled sealing structure for a thermos cup includes a cup body 1, the opening of which is an inwardly extending inner opening structure. The wall of this inner opening can be designed as a straight cylinder, and its lower part can be designed as an inwardly tapering slope or stepped surface to better match the deformable part of the seal 4. A cup lid 2 is provided on the top surface of the cup body 1, and the cup lid 2 is fastened to the top of the cup body 1. An installation groove 3 is provided on the top surface of the cup lid 2, and a seal 4 is fixedly installed on the inner wall of the installation groove 3. The seal 4 is located in the inner opening of the cup body 1. The seal 4 is an annular component made of food-grade heat-resistant silicone or other food-grade sealing rubber materials that can maintain elasticity and are not easily permanently deformed at high and low temperatures. A sliding groove 5 is provided on the top surface of the seal 4, and a pressing component 6 is slidably installed in the sliding groove 5. The pressing component 6 is a rigid component made of stainless steel or other non-toxic and harmless food-grade hard materials. The upper part of the pressing component 6 can serve as a manual button, directly exposed outside the cup lid 2. Users can directly press or pull this button with their fingers to seal and open the cup lid 2. The operation is simple and quick. The bottom surface of the pressing part 6 is fixedly installed with a sealing connector 7, which is also a rigid component made of stainless steel, high borosilicate, or other food-grade hard materials.

[0020] The sidewall of the slide 5 is provided with a first intersection point 8 and a second intersection point 9 from top to bottom. The sidewall of the pressing part 6 is provided with concave and convex points 10. The concave and convex points 10 cooperate with the first intersection point 8 and the second intersection point 9. When the user presses the pressing part 6, the pressing part 6 works downward, causing the concave and convex points 10 on the sidewall of the pressing part 6 to compress and deform the intersection points of the first intersection point 8 and the second intersection point 9 on the sidewall of the slide 5. This causes the first intersection point 8 to expand and compress to seal, and the second intersection point 9 to expand and compress outward, so that the outer wall of the sealing part 4 fits against the inner wall of the inner opening of the cup body 1, achieving a sealing effect.

[0021] Specifically, when the user presses down on the pressing part 6, the pressing part 6 drives the sealing joint 7 at its bottom to move downward together in the groove 5 of the sealing part 4.

[0022] Phase 1: As the pressing element 6 moves downward, the protrusions 10 on its outer sidewall first contact the first intersection point 8 of the sidewall of the groove 5 and generate compression. Because the pressing element 6 is made of a hard material while the sealing element 4 is made of a soft material, this compression forces the material of the sealing element 4 near the first intersection point 8 to undergo downward axial compression deformation, accompanied by outward radial expansion. This expanded material tightly adheres to and seals the upper region of the inner opening of the cup body 1.

[0023] Second stage: As the pressing element 6 continues to move downwards, the protrusions 10 on its outer sidewall begin to contact the second intersection point 9 of the sidewall of the groove 5 and generate compression. This compression generates an outward radial force, forcing the material of the sealing element 4 near the second intersection point 9 to undergo significant outward radial deformation and expansion. This expanded material tightly adheres to and seals the lower region of the inner opening of the cup body 1, especially at the location where the lower part of the inner opening of the cup body 1 is designed as a slope or constriction, forming a strong sealing ring.

[0024] When it is necessary to open, lift the pressing part 6 upwards, and the sealing joint 7 will rise accordingly, completely releasing the squeezing pressure on the seal 4 at the first intersection point 8 and the second intersection point 9. With its excellent elastic recovery force, the seal 4 will automatically rebound from the deformed state to its original shape, thereby breaking away from the tight contact with the inner wall of the cup body 1, allowing the cup lid 2 to open.

[0025] As a preferred embodiment of this example, please refer to [link / reference]. Figures 1-4 As shown, in this embodiment, the pressing member 6 acts as a transmission rod connected to an electrically controlled drive device. This electrically controlled drive device is housed within the mounting groove 3 and surrounding space of the cup lid 2, and includes: Electric motor: such as a miniature DC geared motor, used as a power source.

[0026] Transmission mechanism: Converts the rotary motion of the motor into the linear motion required by the pressing component 6. This mechanism can be a worm gear mechanism, a lead screw and nut mechanism, or a gear and rack mechanism, etc.

[0027] Storage battery: supplies power to the motor and control circuits.

[0028] Control module: It can receive commands from physical buttons, touch sensors or wireless receiver modules (such as Bluetooth) to control the forward and reverse rotation of the motor.

[0029] Users trigger commands (such as pressing the electronic button on the cup lid 2 or sending commands via a mobile app), and the control module drives the motor to rotate. This, through a transmission mechanism, precisely pushes or pulls the pressing component 6 to complete the automatic sealing or opening action. The simple linear drive structure of this invention greatly facilitates electronic control, enabling the intelligent opening and closing cup lid 2 to be implemented at low cost and with high reliability.

[0030] As a preferred embodiment of this example, please refer to [link / reference]. Figures 1-4 As shown, this sealing structure achieves fundamental structural simplification by abandoning the traditional threaded rotary sealing method. The internal threaded structure of the cup lid 2 is completely eliminated, and it can be manufactured using one-piece injection molding or metal stretch forming processes. This greatly reduces the number of parts, processing steps, and assembly steps, significantly reducing production costs.

[0031] More importantly, the simplified structure directly frees up valuable space inside the cup lid 2 that had been occupied for a long time. The resulting open and complete internal cavity provides unprecedented physical conditions for integrating multiple functional modules. For example, other feasible solutions such as the aforementioned electronically controlled drive device.

[0032] Working principle: In use, when the user presses down on the pressing part 6, the pressing part 6 drives the sealing joint 7 at its bottom to move downward together within the groove 5 of the sealing part 4. As the pressing part 6 moves downward, the protrusions 10 on its side wall first contact the first intersection point 8 of the side wall of the groove 5 and generate compression, forcing the material of the sealing part 4 near the first intersection point 8 to undergo downward axial compression deformation and outward radial expansion, thereby tightly fitting and sealing the upper area of ​​the inner opening of the cup body 1. As the pressing part 6 continues to move downward, the protrusions 10 begin to contact the second intersection point 9 of the side wall of the groove 5 and generate compression. The compression here generates an outward radial force, forcing the material of the sealing part 4 near the second intersection point 9 to undergo significant outward radial deformation and expansion, thereby tightly fitting and sealing the lower area of ​​the inner opening of the cup body 1. Especially at the lower part of the inner opening of the cup body 1, which is designed with a slope or constriction, a strong sealing ring is formed, achieving a complete sealing effect.

[0033] When it is necessary to open, lift the pressing part 6 upwards, and the sealing joint 7 will rise accordingly, completely releasing the squeezing pressure on the seal 4 at the first intersection point 8 and the second intersection point 9. The seal 4, relying on its own elastic restoring force, will automatically spring back to its original shape from the squeezed deformation state, thereby breaking away from the tight contact with the inner wall of the cup body 1, allowing the cup lid 2 to open.

[0034] In electronic control mode, the pressing component 6 is connected to an electronically controlled drive device, including a motor, a transmission mechanism, a battery, and a control module. The user triggers the motor to rotate forward or backward via a command such as pressing an electronic button or through a wireless signal. The control module then converts the rotational motion into linear motion via the transmission mechanism, automatically pushing or pulling the pressing component 6 to complete the sealing or opening action, thus achieving intelligent operation.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
