Detailed Description

To achieve the above objects and advantages, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 4, the present invention discloses a cup lid structure, including: the novel multifunctional water cup comprises an upper cover 1, a lower cover 2 and an inner insert 3, wherein the inner insert 3 is arranged between the upper cover 1 and the lower cover 2, the lower cover 2 is provided with a drinking hole 211 and a containing chamber 212, a first air hole 213 is arranged in the containing chamber 212, the upper cover 1 is provided with a second air hole 13, the side wall of the containing chamber 212 is provided with at least one layer of main ladder 2121, the side wall of the inner insert 3 is provided with at least one layer of auxiliary ladder 33, the auxiliary ladder 33 is arranged on the main ladder 2121 in a clearance fit manner, the inner insert 3 is provided with a lower cavity 31, a space exists between the bottom of the inner insert 3 and the bottom of the containing chamber 212, and the first air hole 213 and the second air hole 13 are aligned to the bottom of the inner insert 3.

Therefore, as shown in fig. 4, since the first air hole 213 is disposed in the accommodating chamber 212 of the lower cover 2 of the present invention, the second air hole 13 is disposed on the upper cover 1, the main step 2121 is disposed on the sidewall of the accommodating chamber 212, the insert 3 is disposed with the auxiliary step 33, the auxiliary step 33 is clearance-fitted on the main step 2121 to realize the connection and fixation of the insert 3 with the upper cover 1 and the lower cover 2, when the present invention is covered on a cup with hot drink, the hot air generated by the cup can flow from the first air hole 213 to the cavity formed by the space between the bottom of the insert 3 and the bottom of the accommodating chamber 212, i.e. the first layer of the cup is exhausted, then flows to the lower cavity 31 of the insert 3 through the gap between the auxiliary step 33 and the main step 2121, i.e. the second layer of the cup is exhausted, and finally flows out from the second air hole 13, i.e. the third layer of the cup is exhausted, so as to allow the hot air in the cup to flow out quickly, therefore, the balance of the air pressure inside and outside the cup is ensured, the phenomenon that the beverage is poured due to the fact that the cup cover is opened by hot air due to overlarge air pressure inside the cup is effectively prevented, the impact force of the air flowing out of the second air vent 13 is reduced through the effects of first-layer air exhaust, second-layer air exhaust and third-layer air exhaust, and the hot air cannot tell that the upper cover 1 is opened; when the cup is fallen, because the clearance between main ladder 2121 and the vice ladder 33 is less to make the drink in the cup be difficult to ooze the clearance between main ladder 2121 and the vice ladder 33, flow via second bleeder vent 13, consequently the utility model has the characteristics of simple structure just can prevent that the drink from leaking and spilling.

Further, the number of the main steps 2121 and the number of the sub steps are at least two, in this embodiment, the number of the main steps 2121 and the number of the sub steps are two, but not limited thereto, and the gap between the main step 2121 and the sub step 33 located below is larger than the gap between the main step 2121 and the sub step 33 located above, that is, the gap between the main step 2121 and the sub step 33 gradually decreases from bottom to top; the requirement that the impact force of hot air which just flows out of the first air hole 213 is large and needs a large discharge space, and the hot air gradually reduces as the hot air ascends from bottom to top is met, so that the gap between the main step 2121 and the auxiliary step 33 which are positioned below is large, and the hot air which just flows out of the first air hole 213 can be rapidly discharged.

Furthermore, the bottom surface of the accommodating chamber 212 may be an inclined surface, and the first vent hole 213 is disposed at the lower end of the inclined surface, so that the space between the bottom of the insert 3 and the bottom of the accommodating chamber 212 is increased to further accelerate the discharge of the hot air just flowing out of the first vent hole 213.

Then, an inner concave portion 32 is formed on the back surface of the sub-step 33, so that the gap between the sub-step 33 and the main step 2121 is increased, and the connection and fixation between the insert 3 and the upper and

lower covers

1 and 2 can be ensured, so that the hot air of the first vent hole 213 can be rapidly exhausted.

The upper cover 1, the lower cover 2 and the inner insert 3 are made of waterproof paper with 100-degree high temperature resistance, but not limited thereto.

Further, the upper cover 1 is recessed to be formed with the sealing plug 11, the drinking opening 211 is sealed in the sealing plug 11 can be dismantled to convenient to use person can drink the drink in the cup many times, prevents that external spot from polluting and citing mouth 211 and drink.

In order to facilitate the user to open the sealing plug 11, the upper cover 1 can enclose into through some broken line 4 and have an portion of lifting 12, the below of portion of lifting 12 is located to the sealing plug 11 to the user can buckle some broken line 4 and lift the portion of lifting 12 is opened the sealing plug 11, and the user also can directly demolish the portion of lifting 12, promotes the utility model discloses use the flexibility.

Further, lower cover 2 can include upper 21 and lower floor 22, the top middle part of lower floor 22 is located to upper 21, there is the interval at the edge of upper 21 and the edge of lower floor 22, drink mouthful 211 and hold room 212 and all locate upper 21, upper cover 1 lid is located on upper 21, upper 21 and lower floor 22 integrated into one piece, thereby be convenient for the utility model discloses the lid closes the cup.

The lifting portion 12 may be provided with a lifting portion 121 in a protruding manner, and the lifting portion 121 extends out of the upper layer 21, so that a user can lift the lifting portion 12 through the lifting portion 121.

Then, an embedded collar 23 can be convexly arranged below the joint of the upper layer 21 and the lower layer 22, so that the outer side wall of the embedded collar 23 can be utilized to be tightly attached to the inner wall of the cup, and the sealing performance of the cup cover is improved.

In addition, the inside wall of lower floor 22 can be equipped with detains solid portion 221 to utilize detain solid portion 221 to detain in the outer wall of cup, let the utility model discloses can firmly cover on the cup, just detain solid portion 221 and inlay and form the clamping to the cup between the clamping ring 23.

Further, the lower cover 2 may be formed with an embedding portion 214 around the accommodation chamber 212, and the upper cover 1 is recessed to form an embedding edge, which is just tightly embedded in the embedding portion 214, so that the upper cover 1 can be firmly and tightly fixed on the lower cover 2.
