The cup cover upper cover is connected to the cup cover body by a hinge structure, and the water outlet is opened or closed by flipping the cup cover upper cover.

[0003] In order to facilitate direct drinking, a raised water spout is commonly provided on the cup lid body, and a water outlet is formed at the bottom of the water spout and connected to the cup body. The water outlet is generally formed by directly opening a mold by forming a circular water outlet in the cup lid body corresponding to the bottom of the water spout. Since the water outlet has a certain caliber and the water flow rate is large, when the user tilts the cup body to drink water, the water will flow directly from the water spout of the cup lid body at a large flow rate. Excessive water flow may cause the user to choke easily, or the water may easily overflow from the corners of the mouth, affecting normal drinking. In order to limit the water flow rate, the most direct method is to use a straw instead of directly setting a direct drinking water outlet on the cup lid. This will make the cup lid structure complicated, and there are also disadvantages that the straw is difficult to clean and the straw cannot absorb water when there is little water in the cup.

DETAILED DESCRIPTION

[0024] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0025] The directions or positional relationships indicated by terms such as “upper”, “lower”, “left”, “right”, “front”, “back”, and “middle” are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limitations of the present invention.

[0026] Combination Figures 1 to 6As shown, the utility model discloses a flow-limiting cup cover, including a cup cover body 1 and an upper cover 2 that can be opened and closed and connected to the cup cover body. The upper cover 2 is hinged to one side of the cup cover body 1. The side of the cup cover body where the upper cover 2 is hinged is defined as the rear side of the cup cover, and the rear side of the cup cover corresponds to the rear side of the cup cover body 1 and the upper cover 2, as shown in the Y direction in the figure; the side opposite to the rear side of the cup cover is the front side of the cup cover, and the front side of the cup cover corresponds to the front side of the cup cover body 1 and the upper cover 2, as shown in the X direction in the figure. In the utility model, a hollow columnar water outlet 11 is convexly provided on the cup cover body 1. The water outlet 11 in this embodiment is nearly elliptical, and the water outlet 11 can facilitate the drinker to drink directly. At the same time, a rubber plug 21 that can cover and seal the water outlet is protruding downward from the bottom surface of the upper cover 2. The top of the water outlet 11 forms an upper water outlet 111. When the upper cover 2 is covered on the cup cover body 1, the rubber plug 21 covers and seals the upper water outlet 111 to prevent water from leaking out of the water outlet 11.

[0027] As for the connection between the upper cover 2 and the cup cover body 1, the rear end of the upper cover 2 is hinged to the rear side of the cup cover body 1, and a sliding groove 12 is recessed in the front side of the cup cover body 1. A sliding seat 122 that can elastically move forward and backward is provided in the sliding groove 12. The sliding seat 122 can be pressed against the front end of a spring 121. A clamping block 123 is provided on the top surface of the sliding seat 122. A buckle ring 22 is provided downward on the front side of the upper cover 2. The buckle ring 22 can be clamped in the clamping block 123 to limit the position when the upper cover 2 is closed on the cover body 1. When the upper cover 2 needs to be opened, the sliding seat 122 is pushed inward, and the buckle ring 22 can be disengaged from the clamping block 123 after the sliding seat 122 is pushed inward. In this embodiment, there is a hollow portion 1221 at the front end of the sliding seat 122, and a clamping block 123 is protruded on the rear wall of the hollow portion 1221. The clamping block 123 forms a hook block with a downward inclined side surface. Long strip-shaped limit blocks 124 are protruded on the inner walls on both sides of the sliding groove 122. Long strip-shaped limit grooves 125 longer than the limit blocks 124 are respectively provided on the two side walls of the sliding seat 122 corresponding to the limit blocks 124, and the limit blocks 124 slide in the limit holes 125. When the upper cover 2 and the lower cover 1 are closed, the buckle 22 enters the hollow portion 1221, and its lower side first abuts against the upper surface of the block 123. Since the upper surface of the block 123 is inclined toward the front and lower side, when a downward external force is applied to the upper cover 2, the buckle 22 will slide downward on the upper surface of the block 123, and at the same time push the sliding seat 122 into the sliding groove 12, compressing the spring 121, and finally making the inner side of the hanging rod 22 abut against the bottom surface of the block 123, so as to form a stable state in which the upper cover 2 and the lower cover 1 are closed. A limiting rod 126 can also be provided on the upper side of the inner part of the sliding groove 12, and a concave limiting section 127 is provided on the upper surface of the rear half of the sliding seat 122 corresponding to the limiting rod 126. While limiting the sliding seat 122, the front half of the sliding seat 122 without the limiting section 127 cannot slide into the sliding groove 12.

[0028] Furthermore, a stop edge 23 can be provided on the front side of the upper cover 2 above the buckle 22, and a U-shaped lock buckle 13 can be hinged at the position corresponding to the stop edge 23 on the front side of the cup cover body 1. After the upper cover 2 is covered on the cup cover body 1, the lock buckle 13 can be rotated upward and buckled on the stop edge 23 to lock the covered state, making the upper cover 2 more stable. For the rear side of the upper cover 2, a hinge shaft 14 can be provided on the rear side of the cup cover body 1, and two hinge rings 24 can be provided on the rear side of the upper cover 2 and respectively sleeved on both ends of the hinge shaft 14 to achieve hinge connection. The cup cover body 1 may also be provided with an annular rubber band 3, which passes through the bottom of the hinge shaft 14 and is connected to a hook 25 arranged on the inner rear side of the upper cover 2. Due to the elastic potential energy of the annular rubber band 3, the hinge ring 24 on the rear side of the upper cover 2 can be directly driven to rotate on the hinge shaft 14, without the need to manually rotate the upper cover 2 after the cover is released. At the same time, the annular rubber band 3 can also keep the open state stable, so there is no need to worry that the upper cover 2 will rotate downward due to gravity and hit the user when drinking water. A handle 4 is also hinged at both ends of the hinge shaft 14 (outside the hinge ring 24), so that the user can take the cup cover and the water cup for easy carrying.

[0029] In the utility model, the water spout 11 is located between the front side and the rear side of the top surface of the cup cover body 1, and the side of the water spout 11 close to the front side of the cup cover forms a drinking side A that can be close to the lower lip of the drinker. In order to prevent the water flow in the water spout 11 from being too large when the user drinks water, a water retaining boss 15 is convexly provided on the inner wall of the drinking side A of the water spout 11, which can limit the water flow from the water spout too fast. The water retaining boss 15 can be located behind the sliding groove to form a retreat position, so that the structure of the cup cover body on the front side is more compact. Of course, the water retaining boss can also be in the form of a water retaining sheet or a water retaining block convexly provided in the drinking side A of the water spout. Through the water outlet channel formed by the water spout 11, the water flow in the corresponding inlet (inlet) direction can be properly blocked by the water retaining boss 15, which can prevent choking caused by excessive water output and tilting out.

[0030] Further, combined with Figure 2 , Figure 4 , Figure 6 As shown, the opposite side of the drinking side A forms the water inlet side B, the height of the drinking side A on the cup cover body 1 is higher than the water inlet side B, and the side wall of the water outlet 11 gradually shrinks from bottom to top. In this embodiment, the drinking side of the water outlet 11 is tilted from bottom to top toward the front side direction X of the cup cover, and the water inlet side B is tilted from bottom to top toward the drinking side 1, and the inclination angle of the drinking side A is smaller than the inclination angle of the water inlet side B, which can be more ergonomically designed and meet the requirement of smooth water discharge. At the same time, a lower water outlet 112 is formed on the inner bottom surface of the cup cover body 1 at the bottom of the water outlet 11, and a water retaining boss 15 forms a stepped boss inside the water outlet 11, as shown in FIG. Figure 4As shown in Figure 5, the top of the water-blocking boss 15 blocks the partial cross section of the blowing nozzle in the middle of the water outlet, and the bottom of the water-blocking boss 15 blocks the part of the lower water outlet near the drinking side. Through the above design, when pouring drinking water, especially when the amount of water is large, the best drinking direction for the user is to drink from the front side X. When the water flows into the drinking side A of the water outlet 11, it will be blocked by the water-blocking boss 15. When the user puts his mouth on the water outlet 11, due to the presence of a flow-limiting boss in the drinking side A, the water below is prevented from gushing out too quickly and excessively when the cup cover is tilted, so that the water will not flow out or overflow from the upper water outlet 111 due to excessive and rapid gravity, causing the user to choke or water overflow or spill. The user can make timely adjustments according to the drinking situation to avoid the situation of excessive water discharge that is caught off guard during direct drinking. Of course, when the amount of water is small, the drinking angle can be appropriately changed to bypass the water retaining boss 15, and when the drinking side B is tilted and gradually contracted, smooth drinking can be achieved.

[0031] like Figure 7 As shown, the utility model also discloses a flow-limiting water cup, which includes a cup body 6 and the above-mentioned flow-limiting cup cover, the flow-limiting cup cover is installed on the cup body 6, and the flow-limiting cup cover and the cup body 6 can be screwed together. A sealing ring 5 (such as Figure 6 ), to prevent water leakage.

[0032] The above are only embodiments of the push cup cover and the water cup of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
