Description

Technical Field

[0001] This application relates to the field of drinking cup technology, specifically to a microchannel heat exchange module and a microchannel heat exchange cup. Background Technology

[0002] In daily life, people often use straw-type drinking cups to drink hot water or liquids that are too hot, either for insulation or due to drinking habits. However, existing straw-type drinking devices typically simply direct the water flow directly from the inside of the cup to the straw, lacking an active or passive safety temperature control mechanism. When a user sips the water, if the liquid inside the cup is too hot (such as freshly poured boiling water), the hot water will directly reach the user's mouth, posing a significant risk of burns. This risk is particularly prominent for children or users unfamiliar with the temperature changes inside a cup. Although some cups employ double-layer insulation or heat preservation structures, these structures can only delay the temperature drop; they cannot monitor the water flow in real time or provide hazard warnings while the user is drinking, nor can they automatically cut off the water flow when high temperatures occur. Therefore, designing a simple drinking safety device that can detect the real-time temperature of the water flow and automatically cut off the hot water flow in dangerous situations has become an urgent technical problem to be solved.

[0003] Furthermore, to facilitate sipping residual liquid from the bottom of the cup, many straw cups have a flexible tube extending downwards to the bottom of the cup at the end of the straw. In existing technology, the method of securing this flexible tube to the straw or cup is often unreliable, frequently employing simple plug-in or snap-fit ​​connections. When the cup is shaken, tilted, or subjected to external impact during use, the flexible tube connected to the water inlet can easily loosen or even detach completely. Once the tube detaches, the user will be unable to properly sipping liquid through the straw, severely impacting the cup's normal function and user experience. Therefore, improving the stability and reliability of this crucial connection point is an important direction for enhancing the practicality of straw cups. Summary of the Invention

The multiple sets of secondary microfluidic heat exchange pipes each include a secondary inlet and a secondary outlet. The main inlet and multiple secondary inlets are connected to the inlet through a first connecting structure. The main outlet and multiple secondary outlets are connected to the outlet through a second connecting structure.

[0008] A cooling element is fitted onto the side opposite to the water circuit body and the microfluidic heat exchange pipe, and is configured such that when drinking water with a temperature not higher than a first temperature flows out of the outlet through the microfluidic heat exchange pipe from the inlet, the water temperature drops to a second temperature.

[0013] In some embodiments, the main temperature control valve is electrically connected to the plurality of secondary valves, and the main temperature control valve is provided with a temperature sensor and an electromagnetic control valve core.

[0014] In some embodiments, it also includes:

[0015] A temperature sensor is installed at the water inlet to monitor the drinking water temperature in real time.

[0016] A control valve is installed at the water outlet;

[0017] When the temperature sensor detects that the drinking water temperature is higher than the first temperature, the control valve closes the water outlet.

[0018] In some embodiments, the main microchannel heat exchange pipe and the multiple sets of secondary microchannel heat exchange pipes are arranged in a serpentine coil inside the water circuit body, and the main microchannel heat exchange pipe and the multiple sets of secondary microchannel heat exchange pipes are arranged in parallel.

[0020] A limiting module is installed on the inner wall of the water inlet to lock the drinking water hose.

[0021] According to the microchannel heat exchange module of claim 1, the limiting module includes an elastic connecting block and an elliptical elastic limiting block.

[0022] One end of the elastic connecting block is fixedly connected to the inner wall of the water inlet, and the other end is fixedly connected to the elliptical elastic limiting block; the side of the elliptical elastic limiting block opposite to the elastic connecting block is press-fitted against the drinking hose.

[0023] In some embodiments, the elliptical elastic limiting block has a hollow ring structure, and the major axis of the elliptical elastic limiting block is perpendicular to the insertion direction of the drinking hose.

[0024] In some embodiments, the elastic connecting blocks are evenly spaced along the circumference of the water inlet, and the elastic connecting blocks are made of rubber.

[0026] Compared with the prior art, this application has at least one of the following technical effects:

[0028] Furthermore, this application adds a main temperature control valve at the main inlet of the main microfluidic heat exchange pipe and a secondary valve at the secondary outlet of the secondary microfluidic heat exchange pipe. The main temperature control valve synchronously controls all secondary valves according to the temperature, which solves the problem in the prior art where users are easily scalded when drinking hot water through a straw because they cannot predict the temperature of the outlet water. It achieves the effect of actively detecting the temperature before the water flows out and automatically locking all water channels when the temperature is too high, thereby intelligently preventing scalding and improving the safety of use.

[0029] In addition, this application solves the problem in the prior art that the hose used for water absorption inside the water cup is not securely connected and is prone to loosening or falling off during shaking or use, resulting in inconvenience in water absorption, by setting a limiting module inside the water inlet of the microfluidic heat exchange module. The limiting module includes an elliptical elastic limiting block and an elastic connecting block. It achieves the effect of reliably clamping the hose by using elastic deformation and rebound force to ensure that the hose is installed firmly and the connection is reliable, thereby improving the water absorption stability and ease of use.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] In related technologies, if the liquid temperature in the cup is too high when a user is sucking on the water, the water will directly reach the user's mouth at a high temperature, which can easily cause burns.

[0045] To address the aforementioned problems, this application provides a microfluidic heat exchange module, disposed in a water cup, for cooling drinking water. The module includes: a water circuit body, comprising an inlet at one end and an outlet at the other end; and microfluidic heat exchange pipes disposed between the inlet and outlet of the water circuit body, comprising a main microfluidic heat exchange pipe and multiple sets of secondary microfluidic heat exchange pipes. The main microfluidic heat exchange pipe includes a main inlet and a main outlet. The set of secondary microchannel heat exchange pipes includes a secondary inlet and a secondary outlet. The main inlet and multiple secondary inlets are connected to the main inlet through a first connecting structure, and the main outlet and multiple secondary outlets are connected to the outlet through a second connecting structure. A cooling element is attached to the side of the water circuit body opposite to the microchannel heat exchange pipe, and is configured such that when drinking water with a temperature not higher than a first temperature flows from the inlet through the microchannel heat exchange pipe and out of the outlet, the water temperature drops to a second temperature.

[0046] This application sets up a microchannel heat exchange module, and inside the microchannel heat exchange module, it sets up a main microchannel heat exchange pipe and a secondary microchannel heat exchange pipe. It adds cooling plates to the main microchannel heat exchange pipe and the secondary microchannel heat exchange pipe to reduce the drinking water temperature flowing through the microchannel heat exchange module. This allows users to drink water without worrying about the water temperature being too high and burning their mouths, which is especially important for children and improves safety.

[0047] The optional embodiments of this application are described in detail below with reference to the accompanying drawings.

[0048] like Figure 1 As shown in the figure, this application embodiment provides a microchannel heat exchange module, which is installed in a water cup for cooling drinking water. The microchannel heat exchange module includes a water circuit body 10, a microchannel heat exchange pipe 20, and a cooling chip 30.

[0049] The waterway body 10 includes an inlet 11 located at one end of the waterway body 10 and an outlet 12 located at the other end of the waterway body 10.

[0050] A microfluidic heat exchange pipe 20 is disposed between the inlet 11 and the outlet 12 of the water circuit body 10, including a set of main microfluidic heat exchange pipes 21 and multiple sets of secondary microfluidic heat exchange pipes 22. The main microfluidic heat exchange pipe 21 includes a main inlet 211 and a main outlet 212. The multiple sets of secondary microfluidic heat exchange pipes 22 each include a secondary inlet 221 and a secondary outlet 222. The main inlet 211 and the multiple secondary inlets 221 are connected to the inlet 11 through a first connecting structure 23. The main outlet 212 and the multiple secondary outlets 222 are connected to the outlet 12 through a second connecting structure 24. Both the main microfluidic heat exchange pipe 21 and the secondary microfluidic heat exchange pipes 22 provide a heat exchange channel for the water flow.

[0051] A cooling chip 30 is fitted onto the side of the water circuit body 10 opposite to the microfluidic heat exchange pipe 20. It is configured such that when drinking water at a temperature not exceeding a first temperature flows from the inlet 11 through the microfluidic heat exchange pipe 20 and out of the outlet 12, the water temperature drops to a second temperature. The cooling chip 30 is a semiconductor cooling chip, located on the other side of the water circuit body 10, with its cold end face fixedly attached to the surface of the water circuit body 10.

[0052] In some embodiments, the microfluidic heat exchange module further includes a main temperature control valve 213 and multiple secondary valves 223. The main temperature control valve 213 is disposed at the main inlet 211 of the main microfluidic heat exchange pipe 21 for real-time monitoring of the drinking water temperature. The multiple secondary valves 223 are respectively disposed at the secondary outlets 222 of the secondary microfluidic heat exchange pipes 22. When the drinking water temperature is higher than the first temperature, the main temperature control valve 213 closes the main microfluidic heat exchange pipe 21 and controls the multiple secondary valves 223 to close the multiple sets of secondary microfluidic heat exchange pipes 22.

[0053] In some embodiments, the main temperature control valve 213 is electrically connected to the plurality of secondary valves 223, and the main temperature control valve 213 is provided with a temperature sensor and an electromagnetic control valve core.

[0054] To ensure the reliability and consistency of the anti-scalding function, the opening and closing of the secondary valve 223 is controlled by the main temperature control valve 213. This means that the main temperature control valve 213 not only controls the on / off state of the main microfluidic heat exchange pipe 21, but also acts as a main controller, synchronously controlling the state of all secondary valves 223. The main temperature control valve 213 is equipped with a high-precision temperature sensing element, such as a bimetallic strip, a thermistor, or a shape memory alloy spring. When the main temperature control valve 213 detects that the water flow temperature at the inlet of the main microfluidic heat exchange pipe 21 exceeds the preset safety threshold, such as 50 degrees Celsius, the main temperature control valve 213 closes itself. At the same time, the main temperature control valve 213 will trigger a linkage mechanism or send an electrical signal, such as electronic control, so that all secondary valves 223 are also locked and closed synchronously. Conversely, when the temperature drops to a safe range, the main temperature control valve 213 opens and simultaneously releases the lock on the secondary valve 223, allowing water to flow through all pipes. This centralized control design ensures that every stream of water flowing through the outlet 12 has undergone temperature safety verification, avoiding the risk of burns caused by some water flowing from the secondary microchannel heat exchange pipe 22 not being tested or insufficiently cooled, thus improving the safety of use.

[0055] Since the main temperature control valve 213 is located at the main inlet 211 of the main microfluidic heat exchange pipe 21, when the main temperature control valve 213 detects that the water temperature is too high, it provides sufficient time for the secondary valve 223 to respond with the closing signal. This is because at this time, the water flow in the multiple sets of secondary microfluidic heat exchange pipes 22 has just reached the secondary inlet 221, but has not yet reached the secondary outlet 222. Before this, the secondary valve 223 can close the multiple sets of secondary microfluidic heat exchange pipes 22, which can completely avoid the risk of scalding caused by the response time.

[0056] In some embodiments, the main temperature control valve 213 can also be located at the main outlet 212 of the main microfluidic heat exchange pipe 21, which enables precise collection and distribution of water flow. The main temperature control valve 213 is fixed at the main outlet 212 of the main microfluidic heat exchange pipe 21. Similarly, the secondary valve 223 is fixed at the secondary outlet 222 of the secondary microfluidic heat exchange pipe 22. This arrangement allows the main temperature control valve 213 and the secondary valve 223 to directly detect and control the temperature of the water flow about to leave the microfluidic heat exchange pipe, ensuring the real-time and accuracy of temperature detection. The fixing method can be threaded connection, snap-fit ​​connection or integral injection molding, ensuring the sealing and firmness of the connection under high water pressure or temperature changes.

[0057] The second connecting structure 24 can be designed as a confluence chamber, which has interfaces that connect to the main outlet 212 and all secondary outlets 222 respectively. When all valves are open, the cooled water from the main microchannel heat exchange pipe 21 and all secondary microchannel heat exchange pipes 22 first passes through their respective valves, and then all enter the confluence chamber to mix and further cool down. Finally, it is consumed by the user through the unified outlet 12.

[0058] In some embodiments, such as Figure 2 As shown, the microfluidic heat exchange module also includes a temperature sensor 25 and a control valve 26. The temperature sensor 25 is located at the water inlet 11 and is used to monitor the drinking water temperature in real time. The control valve 26 is located at the water outlet 12. When the temperature sensor 25 detects that the drinking water temperature is higher than the first temperature, the control valve 26 closes the water outlet 12.

[0059] In some embodiments, the main microchannel heat exchange pipe 21 and the multiple sets of secondary microchannel heat exchange pipes 22 are arranged in a serpentine coil inside the water circuit body 10, and the main microchannel heat exchange pipe 21 and the multiple sets of secondary microchannel heat exchange pipes 22 are arranged in parallel.

[0060] In some embodiments, such as Figure 3 As shown, the microfluidic heat exchange module also includes a limiting module 40, which is disposed on the inner side wall of the water inlet 11 and is used to clamp the drinking water hose 60.

[0061] In some embodiments, the limiting module 40 includes an elastic connecting block 401 and an elliptical elastic limiting block 402; one end of the elastic connecting block 401 is fixedly connected to the inner wall of the water inlet 11, and the other end is fixedly connected to the elliptical elastic limiting block 402; the elliptical elastic limiting block 402 is press-fitted against the drinking hose 60 on the side opposite to the elastic connecting block 401.

[0062] In some embodiments, the elliptical elastic limiting block 402 has a hollow ring structure, and the major axis of the elliptical elastic limiting block 402 is perpendicular to the insertion direction of the drinking hose 60.

[0063] In some embodiments, the elastic connecting blocks 401 are evenly spaced along the circumference of the water inlet 11, and the elastic connecting blocks 401 are made of rubber.

[0064] In order to achieve reliable installation and fixation of the drinking water hose 60 and prevent the drinking water hose 60 from accidentally falling off during use, thereby improving water absorption stability, the microchannel heat exchange module also includes a limiting module 40. The limiting module 40 is set inside the water inlet 11 and is used to provide elastic clamping force when the drinking water hose 60 is inserted.

[0065] The number of elastic connecting blocks 401 is preferably two. The two elastic connecting blocks 401 are fixedly connected to both sides of the elliptical elastic limiting block 402. For example, the elastic connecting block 401 and the elliptical elastic limiting block 402 can be integrally formed, or they can be firmly fixed together by high-temperature welding, adhesive bonding, etc. In addition, the two elastic connecting blocks 401 are respectively connected to the inner wall of the water inlet 11. This connection can be a fixed connection, such as by embedding, bonding or welding, so that the limiting module 40 is installed as a whole in the hollow channel of the water inlet 11. When the drinking hose 60 is inserted, the outer wall of the drinking hose 60 will squeeze the elliptical elastic limiting block 402. The elliptical shape of the elliptical elastic limiting block 402 forces it to deform under radial pressure, and at the same time drives the elastic connecting blocks 401 on both sides to elastically stretch or compress. After deformation, the entire limiting module 40 generates a rebound force pointing to the radial center of the drinking hose 60, thereby firmly fixing the drinking hose 60.

[0066] Both the elliptical elastic limiting block 402 and the elastic connecting block 401 are made of elastic materials, such as food-grade silicone, rubber, or thermoplastic elastomer (TPE). These materials not only have good elasticity and resilience but are also safe and non-toxic, making them suitable for use in drinking water appliances. The elliptical shape of the elliptical elastic limiting block 402, combined with the elastic deformation capability of the elastic connecting block 401, provides a progressive, enveloping clamping force when the drinking water hose 60 is inserted, ensuring the sealing and stability of the connection.

[0067] The water circuit body 10, microchannel heat exchange pipe 20, main temperature control valve 213 and secondary valve 223 inside the microchannel heat exchange module are known to those skilled in the art to constitute a liquid heat exchange and safe temperature control flow path, and their specific connection relationship will not be described here.

[0068] This application also provides a microfluidic heat exchange cup, including the microfluidic heat exchange module as described in any of the preceding claims. The microfluidic heat exchange cup aims to solve the problems in the prior art where the outlet water temperature is unpredictable when drinking hot water, which can easily lead to scalding, and the problem that the water absorption hose inside the cup is not securely connected and is prone to detachment.

[0069] Specifically, such as Figure 4 As shown, the microfluidic hot water cup includes a cup body 100 and a straw 70 disposed on the top of the cup body 100; the microfluidic hot water cup also includes a microfluidic heat exchange module installed inside the cup body 100; the cup body 100 serves as a cavity for containing liquid, the straw 70 is used for the user to draw liquid, and the microfluidic heat exchange module, as a core functional component, is used for cooling and safety control of the liquid inside the cup body 100.

[0070] When the user sucks through the straw 70, a negative pressure is generated inside the cup body 100. The liquid inside the cup body 100 is guided by the pressure difference and enters the inlet 11 of the microfluidic heat exchange module through the drinking hose 60. During use, one end of the drinking hose 60 is stably fixed inside the inlet 11. This is achieved by the limiting module 40 set inside the inlet 11. When the drinking hose 60 is inserted, the outer wall of the drinking hose 60 will squeeze the elliptical elastic limiting block 402 of the limiting module 40, causing the elliptical elastic limiting block 402 and the elastic connecting block 401 to undergo elastic deformation. The resulting rebound force will firmly clamp the drinking hose 60, preventing the drinking hose 60 from shaking or falling off during use.

[0071] After the liquid enters the inlet 11, it is simultaneously diverted into the main microchannel heat exchange pipe 21 and the secondary microchannel heat exchange pipe 22 located inside the microchannel heat exchange module. As the liquid flows through these pipes, it exchanges heat with the microchannel heat exchange module. Before exiting the pipes, the water flows through its respective valves. The main temperature control valve 213 of the main microchannel heat exchange pipe 21 continuously monitors the water temperature. When the main temperature control valve 213 detects that the water temperature is too high (e.g., exceeding the safe temperature), the main temperature control valve... Valve 213 will automatically close, and at the same time, the secondary valve 223 controlled by the main temperature control valve 213 will also close synchronously, thereby blocking all high-temperature water flow and preventing scalding. When the main temperature control valve 213 detects that the water temperature is moderate, the main temperature control valve 213 and all secondary valves 223 remain open. The cooled water flows through the main temperature control valve 213 and the secondary valves 223 respectively, and then gathers at the outlet 12. Finally, it is safely drunk by the user through the straw 70 connected to the outlet 12.

[0072] This application sets up a microchannel heat exchange module, and inside the microchannel heat exchange module, it sets up a main microchannel heat exchange pipe and a secondary microchannel heat exchange pipe. It adds cooling plates to the main microchannel heat exchange pipe and the secondary microchannel heat exchange pipe to reduce the drinking water temperature flowing through the microchannel heat exchange module. This allows users to drink water without worrying about the water temperature being too high and burning their mouths, which is especially important for children and improves safety.

[0073] Furthermore, this application adds a main temperature control valve at the main inlet of the main microfluidic heat exchange pipe and a secondary valve at the secondary outlet of the secondary microfluidic heat exchange pipe. The main temperature control valve synchronously controls all secondary valves according to the temperature, which solves the problem in the prior art where users are easily scalded when drinking hot water through a straw because they cannot predict the temperature of the outlet water. It achieves the effect of actively detecting the temperature before the water flows out and automatically locking all water channels when the temperature is too high, thereby intelligently preventing scalding and improving the safety of use.

[0074] In addition, this application solves the problem in the prior art that the hose used for water absorption inside the water cup is not securely connected and is prone to loosening or falling off during shaking or use, resulting in inconvenience in water absorption, by setting a limiting module inside the water inlet of the microfluidic heat exchange module. The limiting module includes an elliptical elastic limiting block and an elastic connecting block. It achieves the effect of reliably clamping the hose by using elastic deformation and rebound force to ensure that the hose is installed firmly and the connection is reliable, thereby improving the water absorption stability and ease of use.

Similar or identical parts between embodiments can be referred to interchangeably. For the systems or apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple, and relevant parts can be referred to the method section.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
