Description

a thermos cup

technical field

The embodiment of the utility model relates to the technical field of daily necessities, in particular to a thermos cup.

Background technique

At present, there are many types of thermos cups on the market, which can facilitate people to carry hot water. Existing thermos cups have a better thermal insulation effect, and it is easy to cause high water temperature for a long time. Although this is beneficial to the maintenance of hot water, when people are active outdoors and are in urgent need of drinking water, they cannot cool the water in a short time. Extremely inconvenient. Moreover, there is no condition to cool the hot water in time when going out. If the whole cup is opened and cooled, dust will inevitably fall into it, and it will cause the temperature of the water in the whole thermos cup to drop, which will affect the next drinking.

Existing thermos cups that are convenient to keep cool are usually designed with an independent heat preservation inner cover and heat preservation outer cover. The outer cover is fastened on the outside of the heat preservation inner cover. When in use, pour the hot water in the cup into the thermal insulation outer cover to let it cool down, and then drink it. This thermos cup avoids putting the whole glass of water to cool when hot water is put to cool, but still cannot avoid dust falling into in the process of putting to cool down, and, when the water in the heat preservation outer cover is put to cool, still can't Need more time, the user needs to wait, still can't satisfy the drinking water demand of the user in time.

As shown in Figure 1, Figure 2, and Figure 3, the utility model embodiment provides a thermos cup, including a thermos cup body 1, a cold water cup body 2 and a cup cover 3, and the cup cover 3 is covered on the top of the thermos cup body 2 , The cold water cup body 2 is arranged between the thermos cup body 1 and the cup cover 3 .

As shown in Figures 4, 5 and 6, the cold water cup 2 includes a body 21, a first partition 22, a second partition 26 below the first partition 22, a catheter 23 and a one-way valve 24 , the first partition 22 and the second partition 26 are arranged inside the body 21, and form a cold water cavity 211 with the body 21, and the outer surface of the first partition 22 forms a hot water cavity 212 with the body 21; the catheter 23 runs through The second partition is set, and the liquid outlet 231 of the catheter 23 is close to the first partition 22 , and the one-way valve 24 is set to allow the liquid to flow from the thermos cup body 1 into the cold water cavity 211 .

As a preferred embodiment of this embodiment, the second partition 26 is provided with a hot water hole that communicates with the inner cavity of the thermos cup body 1 and the hot water chamber 212, and the hot water outlet connects the inner cavity of the thermos cup body 1 with the hot water. The cavities 212 communicate. A hot water conduit 25 is also provided inside the body 21, and the hot water conduit 25 communicates with the hot water hole.

As a preferred embodiment of this embodiment, the partition 22 is a bent partition, which is formed by connecting the upper wing 221, the web 222 and the lower wing 223, and the top of the catheter 23 is fixed on the upper wing 221. the underside. The top of the hot water conduit 25 passes through the lower wing plate 223 to form a hot water outlet.

Preferably, the cold water cup body 2 is screwed to the thermos cup body 1 . Specifically, an internal thread is provided under the inner wall of the body 21 , and an external thread is provided outside the mouth of the thermos cup body 1 , and the internal thread and the external thread are screwed together.

Preferably, the cup cover 3 is screwed or hinged to the cold water cup body 2 . When the two are screwed, the opening mode of the cup cover 3 is a rotary opening; when the two are hinged, the opening mode of the cup cover 3 is a clamshell opening. It is explained here that the opening method of the cup lid 3 can also be a quick-opening type, a straw type, etc., and the opening method does not limit the present invention.

The cold water cup body 2 is a transparent material, and the structure is a single layer. In order for the user to observe the amount of water in the cold water cup, and the single-layer structure helps the water in the cold water cup to dissipate heat.

The structure of the thermos cup body 1 is a double-layer structure, both of which are made of food-grade stainless steel, and the middle of the two-layer structure is vacuumized to prevent the temperature of the internal liquid from radiating outwards and improve the heat preservation effect.

The thermos cup also includes a silica gel anti-skid layer, which is sheathed on the outer wall of the thermos cup body 1, so as to prevent the cup body from slipping during use, and the use is safe and reliable.

The one-way valve 24 includes a valve body 241 and a spool 242, the spool 242 is arranged in the valve body 241, see Fig. 7, Fig. 8, Fig. 9, in this embodiment, the spool of the one-way valve 24 is a steel ball, When the thermos cup is upright, the steel ball prevents the liquid in the cold water chamber 211 from flowing back; when the thermos cup is turned upside down, the steel ball moves to allow the air in the cold water chamber 211 to circulate with the air in the thermos cup to achieve air pressure balance. It should be noted that the valve core 242 used in the embodiment of the present utility model can also be a vertebral plug, and the shape of the valve core 242 is not limited to the present utility model. For other structural forms of the valve core 242, refer to FIG. 10 and FIG. 11 .

When using the thermos cup provided by the embodiment of the present invention, the thermos cup is turned upside down, and the cold water cup body after the inversion is shown in Fig. The mouth 231 flows into the cold water chamber 211. At this time, the valve core 241 in the one-way valve 24 opens the vent hole on the valve body 242, so that while the liquid flows, the air in the cold water chamber 211 enters the inner cavity of the thermos cup body 1, reaching the inner pressure of the thermos cup. Balance, in this process, because there is a height difference between the catheter tube 23 and the one-way valve 24, a pressure difference inside the liquid is generated. According to the formula P=ρgh, the greater the height difference, the greater the pressure. Catheter 23 flows downward while gas moves upward along the one-way valve 24 without interfering with each other. When it is observed that the liquid in the cold water chamber 211 is full, the thermos cup can be erected. After the thermos cup is restored to the upright position, the liquid in the cold water chamber 211 cannot flow back into the thermos cup body 1 due to the effect of the one-way valve 24. middle. Since the outer wall of the cool water chamber 211 is a single-layer structure, the liquid stored in the cool water chamber 211 will dissipate heat quickly. Open the cup cover 3, tilt the thermos cup, the water in the cold water chamber 211 can be drunk directly without waiting, which meets people's urgent need for water replenishment when they are thirsty, and is extremely convenient to use; moreover, in the process of cooling, dust is avoided It is safe and hygienic for sundries to fall into the water; moreover, the thermos cup body 1 can still keep the water in the thermos cup body 1 warm. If you need hot water in the thermos cup body 1, open the cup cover 3 and turn the thermos cup body backward Just tilt the direction, as shown in Figure 5.

Although the utility model has been described in detail with general description and specific examples above, some modifications or improvements can be made on the basis of the utility model, which will be obvious to those skilled in the art. Therefore, the modifications or improvements made on the basis of not departing from the spirit of the utility model all belong to the protection scope of the utility model.
