Description

Technical Field

[0001] This utility model relates to the field of thermos cup technology, and in particular to a vacuum thermos cup. Background Technology

[0002] Vacuum insulated cups are generally made of stainless steel with a vacuum layer to hold water. They have a lid that seals tightly. The vacuum insulation layer slows down the heat dissipation of the liquid inside, thus achieving the purpose of keeping the water warm. Vacuum cups evolved from thermos flasks, and their heat preservation principle is the same; the only difference is that people made the flask into a cup for convenience. Heat is transferred in three ways: radiation, convection, and conduction. The silver inner liner of the vacuum cup reflects the radiation from the hot water, the vacuum between the liner and the body blocks heat conduction, and the bottle, being a poor conductor of heat, prevents heat convection.

[0003] Currently, a Chinese patent discloses a novel vacuum insulated cup (authorization announcement number CN210493615U). The heating device of this invention includes a heating tube and a mounting plate assembly for mounting the heating tube. The heating tube is installed at the bottom of the mounting plate assembly, and the bottom of the mounting plate assembly is supported on a support portion. A positioning fitting is fitted onto the mounting plate assembly to elastically tension the mounting plate assembly within the mounting portion. This invention combines heat preservation and heating functions in a single insulated cup, resulting in good heat preservation and portability. However, in practical use, the above method has the following drawbacks:

[0004] The heating device is installed at the bottom of the inner liner, and the vacuuming between the outer shell and the inner liner is difficult, making production challenging. Utility Model Content

[0005] Therefore, it is necessary to provide a vacuum insulated cup to address the challenges of installing the heating device at the bottom of the inner liner and the difficulty of creating a vacuum between the outer shell and the inner liner, which leads to high production difficulty.

[0006] A vacuum insulated cup includes: an outer shell, a cup lid installed on the top of the outer shell, a stainless steel inner liner fixedly connected inside the outer shell, the top of the stainless steel inner liner being open, and a protrusion corresponding to the cup lid being fixedly connected to the top of the outer shell, and an insulation mechanism being provided on the cup lid.

[0007] The heat preservation mechanism includes a heating tube fixedly connected to the bottom of the cup lid, a touch screen installed at the center of the top of the cup lid, a charging port electrically connected to the heating tube on the surface of the cup lid, and a temperature sensor electrically connected to the touch screen fixedly connected to the bottom of the cup lid.

[0008] In one embodiment, the outer surface of the boss is provided with an external thread, and the inner wall of the cup lid is provided with a corresponding internal thread.

[0009] In one embodiment, a sealing plug corresponding to the opening of the stainless steel inner liner is fixedly connected to the bottom of the cup lid, and the sealing plug is T-shaped.

[0010] In one embodiment, the heat preservation mechanism further includes a heat preservation sleeve disposed between the stainless steel inner liner and the outer shell, the heat preservation sleeve being fitted onto the outer wall of the cup lid.

[0011] In one embodiment, the stainless steel inner liner is configured as a double-layer vacuum inner liner, and the inner wall of the stainless steel inner liner is provided with a plasma plating layer.

[0012] In one embodiment, a double O-ring is provided between the outer wall of the sealing plug and the opening of the stainless steel inner liner, and the O-ring is made of food-grade fluororubber.

[0013] In one embodiment, the charging port is a Type-C interface and has an embedded waterproof silicone plug.

[0014] In one embodiment, the surface of the heating tube is coated with a nano-ceramic thermally conductive layer with a thickness of 0.5-1 mm.

[0015] Beneficial effects

[0016] A heat preservation mechanism is set up, the outer shell is inverted, and the hot water in the stainless steel inner tank is kept warm through the heating tube, which extends the heat preservation time of the water. The stainless steel inner tank is vacuumed, which is technically easy, eliminates air molecules, reduces thermal conductivity, and improves the overall heat preservation performance and heat preservation time.

[0017] The water temperature is detected by a temperature sensor and displayed on the touch screen, allowing users to know the current water temperature in advance before drinking, thus avoiding scalding from high temperatures. Attached Figure Description

[0030] The following is combined with Figures 1-4 This invention describes a vacuum insulated cup.

[0031] In one embodiment, a vacuum insulated cup includes: an outer shell 100, a cup lid 110 mounted on the top of the outer shell 100, a stainless steel inner liner 111 fixedly connected inside the outer shell 100, the top of the stainless steel inner liner 111 being open, and a protrusion 112 corresponding to the cup lid 110 fixedly connected to the top of the outer shell 100, and a heat preservation mechanism 200 provided on the cup lid 110; the heat preservation mechanism 200 includes a heating tube 210 fixedly connected to the bottom of the cup lid 110, a touch screen 212 mounted at the center of the top of the cup lid 110, a charging port 213 electrically connected to the heating tube 210 provided on the surface of the cup lid 110, and a temperature sensor 211 electrically connected to the touch screen 212 fixedly connected to the bottom of the cup lid 110.

[0032] like Figure 2 and Figure 3 As shown, the outer surface of the boss 112 has an external thread, and the inner wall of the cup lid 110 has a corresponding internal thread. The surface of the heating tube 210 is covered with a nano-ceramic thermally conductive layer with a thickness of 0.5-1mm.

[0033] In this embodiment, hot water is added to the stainless steel inner liner 111. The inner and outer threads engage to lock the outer shell 100 and the lid 110 together. The bottom of the lid 110 seals the opening of the stainless steel inner liner 111 to prevent leakage. The outer shell 100 is then inverted. A temperature sensor 211 monitors the water temperature. A heating element 210 heats the water inside the stainless steel inner liner 111. Power is supplied to the heating element 210 via the charging port 213. The heating element 210 has adjustable power, adjusted according to the water temperature detected by the temperature sensor 211. A 0.8mm nano-ceramic thermal conductive layer is applied to its surface to improve thermal efficiency and isolate the water, enhancing safety. A touchscreen 212 is embedded in the top of the lid 110, displaying the temperature and heating level. Type-C charging supports PD 30W fast charging and powers the heating element 210.

[0034] It should be noted that the temperature sensor 211 is connected to the PID temperature control module, which collects water temperature data in real time and feeds it back to the central processing unit. When the detected water temperature is lower than the set threshold, the power of the heating element 210 is automatically increased to a maximum of 30W; conversely, it is reduced to a maintenance power of 10W, with a control accuracy of ±1℃. The cup lid 110 integrates a dry-burn protection circuit: when the temperature sensor 211 is removed from the water surface or the detected temperature is >100℃, the power to the heating element 210 is immediately cut off. The sealing plug is equipped with multiple layers of breathable membrane, covered with a stainless steel sintered mesh, allowing air to pass through but not water to prevent excessive pressure inside the stainless steel inner liner 111. The cup lid 110 has a built-in battery to power the touch screen 212 and the temperature sensor 211.

[0035] like Figure 2 and Figure 3 As shown, a sealing plug corresponding to the opening of the stainless steel inner liner 111 is fixedly connected to the bottom of the cup lid 110. The sealing plug is T-shaped.

[0036] In this embodiment, after the cup lid 110 is locked between the outer shell 100, the vertical side of the T-shaped sealing plug is inserted into the stainless steel inner liner 111, and the horizontal side is pressed against the top of the stainless steel inner liner 111, thereby improving the sealing effect of the stainless steel inner liner 111 and preventing water leakage.

[0037] like Figure 4 As shown, the insulation mechanism 200 also includes an insulation sleeve 220 disposed between the stainless steel inner liner 111 and the outer shell 100, and the insulation sleeve 220 is fitted onto the outer wall of the cup lid 110.

[0038] In this embodiment, the insulation sleeve 220 is provided to further improve the insulation effect. The insulation mechanism 200 is provided with an ion reflective layer from the inside to the outside, a vacuum stainless steel inner liner 111 and an insulation sleeve 220, and the multi-layer insulation setting improves the insulation effect.

[0039] like Figure 4 As shown, the stainless steel inner liner 111 is configured as a double-layer vacuum inner liner, and the inner wall of the stainless steel inner liner 111 is provided with a plasma plating layer.

[0040] In this embodiment, the stainless steel inner liner 111 is manufactured using a tailless vacuum process with a vacuum level of 0.0001 Pa, and the inner wall is coated with a titanium nitride-silver composite plasma layer by magnetron sputtering. The reflectivity is 98.5%, and the scratch resistance rating is >8H.

[0041] like Figure 2 As shown, a double O-ring is provided between the outer wall of the sealing plug and the opening of the stainless steel inner liner 111. The O-ring is made of food-grade fluororubber.

[0042] In this embodiment, the fluororubber O-rings compensate for deformation at high temperatures to prevent leakage. The first O-ring is located near the inner liner opening and can withstand temperatures up to 150°C. The second O-ring is located at the root of the sealing plug to compensate for thermal expansion and contraction.

[0043] like Figure 2 As shown, the charging port 213 is a Type-C interface and has an embedded waterproof silicone plug.

[0044] In this embodiment, the waterproof silicone plug is used to seal the charging port 213 when it is not in use to prevent water from entering.

[0045] Working principle: Hot water is poured into the stainless steel inner liner 111, and the lid 110 is tightened to seal the inner liner 111. Electrical energy is input through the charging port 213 to drive the heating element 210, generating heat. This heat is evenly conducted to the water in the stainless steel inner liner 111 through the nano-ceramic layer, heating and maintaining the water's temperature. As the water heats up, steam is generated. When the pressure exceeds 1 kPa, the breathable and waterproof membrane activates a small amount of venting to maintain the internal pressure at 5-8 kPa. The stainless steel inner liner 111 blocks heat conduction, and the plasma plating reflects radiant heat, reducing heat loss, improving insulation performance, and extending the heat retention time.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
