Detailed implementation manners

[0031] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings.

[0033] To facilitate the understanding of the bottle cap provided in the embodiments of the present application, its application scenario will be described first. The bottle cap provided in the embodiments of the present application is applied to a drinking bottle used by children. The current drinking bottle can be used to hold hot drinks (such as hot water or hot milk and other drinks with relatively high temperatures). However, when the current drinking bottle holds hot drinks, due to the relatively high temperature inside the bottle, the air pressure is relatively high, and the situation of spraying out from the water outlet pipe will occur instantly when the bottle cap is opened. For this reason, the embodiments of the present application provide a bottle cap to improve the effect when the bottle cap is opened and improve the safety of children using the drinking bottle. The following will be described in detail with specific drawings and embodiments.

[0034] Reference Figure 1 and Figure 2 , Figure 1 shows a reference diagram of the usage state of the bottle cap provided in the embodiments of the present application; Figure 2 shows a cross-sectional view of the drinking bottle. When the bottle cap 100 provided in the embodiments of the present application is applied to the drinking bottle, the bottle cap 100 is hermetically connected to the bottle body 200 of the drinking bottle to form a sealed space for holding hot drinks. As Figure 1 and Figure 2 illustrated in the example, when the bottle cap 100 is connected to the bottle body 200, it can be connected by threads. A sealing gasket 300 is provided inside the bottle cap 100. During assembly, the bottle cap 100 is screwed tightly onto the bottle body 200, and the bottle body 200 presses against the sealing gasket 300 to seal the connection between the bottle cap 100 and the bottle body 200 through the elastic deformation of the sealing gasket 300. Of course, the above-mentioned threaded connection and sealing are only a specific connection method. The connection between the bottle cap 100 and the bottle body 200 provided in the embodiments of the present application can also adopt other connection methods, such as the bottle cap 100 and the bottle body 200 are fixedly connected by a buckle, and a stable fixed connection can also be achieved.

[0035] Refer to together Figure 1 and Figure 3 , Figure 3The figure shows a schematic structural diagram of the bottle cap provided by the embodiment of the present application. The bottle cap 100 provided by the embodiment of the present application includes a bottle cap body 110 and a flip cover 120 rotatably connected to the bottle cap body 110. Among them, a water outlet pipe 140 penetrates through the bottle cap body 110, and a ventilation hole 130 is provided on the bottle cap body 110. When the bottle cap 100 is matched with the bottle body 200, the bottle cap body 110 is hermetically connected to the bottle body 200, and both the water outlet pipe 140 and the ventilation hole 130 are communicated with the space inside the bottle body 200, while the flip cover 120 is used to block the water outlet pipe 140 and the ventilation hole 130. When in use, when a child needs to drink a beverage, the flip cover 120 is opened, and both the water outlet pipe 140 and the ventilation hole 130 are exposed, and the child can directly drink the beverage through the water outlet pipe 140. When not needed to drink, the flip cover 120 is closed on the bottle cap body 110, and the flip cover 120 seals the ventilation hole 130 and also seals the water outlet pipe 140. At this time, the whole drinking bottle is sealed and there will be no leakage during carrying, improving the safety during carrying. In a possible embodiment, the water outlet pipe 140 can be connected to a straw, and the straw extends to the bottom of the bottle to facilitate the child to drink. Of course, the straw and the water outlet pipe 140 can be either a split type or an integral type, and no specific limitation is made in the embodiment of the present application.

[0036] Continuing to refer to Figure 1 and Figure 3 as shown, when setting the flip cover 120, the flip cover 120 is rotatably connected to the bottle cap body 110 through a rotating shaft (in Figure 3 the axis around which the flip cover 120 rotates is exemplified by the reference line L2, and this axis is the axis of the rotating shaft). As Figure 1 and Figure 3 shown by the bidirectional arrow example direction, the flip cover 120 rotates around the axis of the rotating shaft to achieve opening and closing.

[0037] Continuing to refer to Figure 1 and Figure 3 , when setting the water outlet pipe 140 and the ventilation hole 130, the water outlet pipe 140 and the ventilation hole 130 are located within the range covered by the flip cover 120, so that when the flip cover 120 is closed to the bottle cap body 110, the water outlet pipe 140 and the ventilation hole 130 can be sealed. In the specific arrangement, the ventilation hole 130 is located on the side of the water outlet pipe 140 facing the rotating shaft. That is, the ventilation hole 130 is located between the water outlet pipe 140 and the rotating shaft, and the ventilation hole 130 is closer to the rotating shaft than the water outlet pipe 140. Exemplarily, as Figure 3 shown by the reference line L1 in, the reference line L1 exemplifies the general direction when the water outlet pipe 140 and the ventilation hole 130 are arranged, and from Figure 3It can be seen that the ventilation hole 130 is located on the side of the water outlet pipe 140 facing the rotating shaft, and the ventilation hole 130 is located close to the water outlet pipe 140. When a child drinks, even if the bottle body is tilted, the risk of the drink leaking from the ventilation hole 130 can be reduced.

[0038] When the flip cover 120 rotates counterclockwise, the flip cover 120 closes, and when it rotates to the first set position, the flip cover 120 covers the bottle cap body 110 and seals the water outlet pipe 140 and the ventilation hole 130. It should be understood that at the first set position, the flip cover 120 can be locked so that the flip cover 120 can maintain a stable connection with the bottle cap 100 and seal the water outlet pipe 140 and the ventilation hole 130. In addition, when the flip cover 120 rotates clockwise, the flip cover 120 opens, and during the rotation process, when the flip cover 120 rotates to the second set position, there is a gap between the flip cover 120 and the ventilation hole 130, and the flip cover 120 still seals the water outlet pipe 140. That is, during the opening process of the flip cover 120, the sealing of the ventilation hole 130 is released first, and the high-pressure gas in the bottle body 200 can escape through the ventilation hole 130 before the water outlet pipe 140 is unsealed, so that when the water outlet pipe 140 is unsealed, the air pressure in the bottle body 200 decreases, thereby reducing the risk of the drink spraying out from the water outlet pipe 140 due to the high air pressure in the bottle body 200.

[0039] When the flip cover 120 rotates to the third set position, the flip cover 120 presses against the water outlet pipe 140 to bend it; wherein, the third set position is located between the first set position and the second set position.

[0040] Through the above description, by arranging the ventilation hole 130 on the side of the water outlet pipe 140 facing the rotating shaft, the ventilation hole 130 is closer to the rotating shaft relative to the water outlet pipe 140. When the flip cover 120 is opened, the ventilation hole 130 can be unsealed before the water outlet pipe 140, so that the air pressure in the drinking bottle can be adjusted through the ventilation hole 130 as soon as possible, reducing the water spraying situation after the water outlet pipe 140 is unsealed and improving the use effect of the drinking bottle. In addition, during the flipping process of the flip cover 120, the end of the flip cover 120 first presses against the water outlet pipe 140 to pre-bend the water outlet pipe 140, which facilitates the subsequent sealing of the water outlet pipe 140 by the flip cover 120.

[0041] Continue to refer to Figure 3 As shown, in the bottle cap 100 provided in the embodiment of the present application, when arranging the water outlet pipe 140 and the ventilation hole 130, in one arrangement scheme, the arrangement direction of the water outlet pipe 140 and the ventilation hole 130 is perpendicular to the axis of the rotating shaft. That is Figure 3In the example, the reference line L1 is perpendicular to L2. When adopting the above arrangement, the arrangement directions of the water outlet pipe 140 and the ventilation holes 130 are arranged along the direction perpendicular to the axis around which it rotates, and this arrangement is along the length direction of the flip cover 120, which can minimize the width of the flip cover 120. In addition, when the ventilation holes 130 are arranged, they are adjacent to the water outlet pipe 140.

[0042] Refer to together Figure 3 and Figure 4 , Figure 4 Fig. shows a schematic structural view of the bottle cap 100 when the flip cover 120 is closed. The ventilation holes 130 provided in the embodiments of the present application are channels for the high-pressure gas in the bottle body 200 to leak out, and the leakage amount thereof affects the efficiency of the reduction of the air pressure in the bottle when the flip cover 120 is opened. Therefore, the ventilation holes 130 provided in the embodiments of the present application adopt holes with a relatively large air flow effect. For example, in an implementable solution, the ventilation holes 130 adopt stepped holes or tapered holes. As Figure 4 shown in Figure 4 the structure of the ventilation holes 130 adopting tapered holes is exemplified. The larger end of the ventilation holes 130 is the air inlet end, and the smaller end is the air outlet end. When the high-pressure gas in the bottle body leaks out, the larger opening end can make the air flow enter the ventilation holes 130 faster. In addition, since the outside of the ventilation holes 130 is a low-pressure area (relative to the high pressure in the bottle body), under the action of the pressure difference, the air flow can quickly flow out from the air outlet end of the ventilation holes 130, improving the efficiency of gas leakage.

[0043] In a specific implementation, the inner wall of the ventilation holes 130 is a convex arc wall 131. That is, the formed tapered hole is a structure similar to a horn. When adopting this structure, the arc wall 131 can guide the air flow to reduce the resistance suffered by the air flow when flowing in the ventilation holes 130. On the other hand, adopting this structure is also convenient for mold opening when preparing the ventilation holes 130. When forming the arc wall 131, the radian of the arc walls 131 on the opposite sides can be different to increase the guiding effect in different directions.

[0044] Of course, when the ventilation holes 130 adopt stepped holes, the larger end of the ventilation holes 130 is also the air inlet end, and the smaller end of the ventilation holes 130 is the air outlet end, and its principle is similar to that of the tapered hole, and will not be elaborated here. It should be understood that when adopting stepped holes, the stepped surface is the guiding surface to reduce the resistance of the gas flowing in the ventilation holes 130.

[0045] It should be understood that the ventilation holes 130 provided in the embodiments of the present application are not limited to the stepped holes or tapered holes in the above examples, and other holes that can increase the gas flow can also be applied to the embodiments of the present application, such as straight holes with a larger diameter or other types of special-shaped holes.

[0046] Continue to refer to Figure 3 andFigure 4 , in an implementable solution, the side wall of the ventilation hole 130 provided in the embodiment of the present application and the water outlet pipe 140 are of an integral structure. That is, during preparation, the ventilation hole 130 and the water outlet pipe 140 are integrally prepared through a mold. As Figure 4 shown, the side wall of the ventilation hole 130 and the side wall of the water outlet pipe 140 are connected as a whole, and the ventilation hole 130 and the water outlet pipe 140 can be integrally formed through a mold. When cooperating with the bottle cap body 110, a first assembly hole and a second assembly hole are correspondingly provided on the flip cover 120. During assembly, the water outlet pipe 140 is inserted through the first assembly hole, and the side wall of the ventilation hole 130 is inserted through the second assembly hole. And the overall structure formed by the water outlet pipe 140 and the ventilation hole 130 is fixed to the bottle cap body 110 by a clamping method. As Figure 4 shown in an example of a clamping method, the part of the water outlet pipe 140 located inside the bottle cap body 110 is fixed to the bottle cap body 110 through a clamping structure, while the side wall of the ventilation hole 130 is directly clamped in the second assembly hole. Of course, in addition to Figure 4 the clamping method shown in the example, the water outlet pipe 140 and the ventilation hole 130 can also be fixed to the bottle cap body 110 through other clamping methods.

[0047] When setting the first assembly hole and the second assembly hole, the shapes of the first assembly hole and the second assembly hole match the shapes of the water outlet pipe 140 and the ventilation hole 130. In addition, the arrangement positions of the first assembly hole and the second assembly hole are determined according to the positions of the water outlet pipe 140 and the ventilation hole 130. Reference can be made to the above limitations on the positions of the water outlet pipe 140 and the ventilation hole 130, and no further elaboration will be given here.

[0048] It should be understood that when the ventilation hole 130 and the water outlet pipe 140 are assembled into the first assembly hole and the second assembly hole, the ventilation hole 130 and the water outlet pipe 140 block and seal the first assembly hole and the second assembly hole to avoid gaps at the connection. The above-mentioned blocking includes, but is not limited to, interference fit between the ventilation hole 130 and the water outlet pipe 140 and the corresponding assembly holes, so as to seal through the deformation of the side walls of the ventilation hole 130 and the water outlet pipe 140; the structures of the ventilation hole 130 and the water outlet pipe 140 located inside the bottle cap body 110 abut against the inner side of the bottle cap body 110 to form a seal.

[0049] In an alternative solution, the first assembly hole and the second assembly hole can be a connected hole. Of course, the first assembly hole and the second assembly hole can also be two independent holes. The specific setting can be determined according to actual needs and is not specifically limited in the embodiment of the present application.

[0050] Continuing to refer to Figure 3 and Figure 4, in an implementable solution, an annular protrusion 112 is provided on the bottle cap body 110. The annular protrusion 112 encloses a region 111 for accommodating the water outlet pipe 140 and the ventilation hole 130. The overall shape of the annular protrusion 112 is an elliptical or approximately elliptical annular structure. The region 111 where the water outlet pipe 140 and the ventilation hole 130 are provided is separated from other regions by the annular protrusion 112. When the flip cover 120 is closed to the bottle cap body 110, the flip cover 120 is closed to the annular protrusion 112, and the ventilation hole 130 and the water outlet pipe 140 are sealed.

[0051] In an implementable solution, when the flip cover 120 cooperates with the bottle cap body 110, the flip cover 120 can be locked by cooperating with the annular protrusion 112. Exemplarily, a clamping protrusion 121 is provided on the flip cover 120. When the flip cover 120 rotates to the first set position, the flip cover 120 is buckled on the annular protrusion 112, and the clamping protrusion 121 is clamped on the edge of the annular protrusion 112. As Figure 3 and Figure 4 shown, a clamping protrusion 121 is provided on the edge of the flip cover 120. When the flip cover 120 is closed to the bottle cap body 110, the flip cover 120 wraps the annular protrusion 112 on the bottle cap body 110, and the clamping protrusion 121 of the flip cover 120 is clamped and fixed with the annular protrusion 112, thereby locking the flip cover 120 so that the flip cover 120 can maintain a sealed state of the water outlet pipe 140 and the ventilation hole 130 when closed.

[0052] In an implementable solution, the part of the bottle cap body 110 located at the annular protrusion 112 has a concave design to increase the space between the flip cover 120 and the bottle cap body 110 when the flip cover 120 is closed to the bottle cap body 110.

[0053] Continuing to refer to Figure 3 and Figure 4 , when the flip cover 120 is in sealed cooperation with the water outlet pipe 140 and the ventilation hole 130, convex structures are provided on the flip cover 120 to be in sealed cooperation with the water outlet pipe 140 and the ventilation hole 130 respectively. The structures of the flip cover 120 in sealed cooperation with the ventilation hole 130 and the water outlet pipe 140 are described below respectively.

[0054] First, the sealed cooperation of the ventilation hole 130 is described. A sealing column 122 is provided on the flip cover 120. The sealing column 122 is located inside the flip cover 120 (on the side of the flip cover 120 facing the bottle cap body 110 when the flip cover 120 is closed to the bottle cap body 110). When the flip cover 120 is closed to the bottle cap body 110, the sealing column 122 presses against the air outlet end of the ventilation hole 130 to seal the ventilation hole 130 when the flip cover 120 is closed. The sealed state is as Figure 4It should be understood that the above-mentioned sealing pressing can be achieved by pressing the sealing column 122 against the end surface of the outlet end of the air vent 130, or by inserting the sealing column 122 into the air vent 130 to block the outlet end. Of course, it is also possible to press against the end surface of the outlet end and insert into the air vent 130 to seal.

[0055] When sealing the water outlet pipe 140, the flip cover 120 is provided with abutting protrusions 123, which are located on the inner side of the flip cover 120 and are used to abut the water outlet pipe 140 to seal it. Correspondingly, an inner concave structure 144 is provided on the outer wall of the water outlet pipe 140 on the side away from the rotating shaft, and the inner concave structure 144 is used to limit the bending direction and bending height of the water outlet pipe 140. When the flip cover 120 rotates to the third setting position, the inner side wall of the end of the flip cover 120 away from the rotating shaft abuts against the water outlet pipe 140, and there is a gap between the abutting protrusions 123 and the water outlet pipe 140. In the process of the flip cover 120 continuing to flip, the inner wall of the end of the flip cover 120 away from the rotating shaft drives the water outlet pipe 140 to bend at the inner concave structure 144, thereby guiding the bending direction of the water outlet pipe 140, and then the abutting protrusions 123 press against the water outlet pipe 140 again. When the flip cover 120 is located at the first setting position, the abutting protrusion 123 abuts between the water outlet end of the water outlet pipe 140 and the concave structure 144, the water outlet pipe 140 is bent at the concave structure 144, and the abutting position of the water outlet pipe 140 and the abutting protrusion 123 is also bent, and the water outlet end is pressed against the bottle cap body 110. During the above-mentioned cooperation, the water outlet pipe 140 is folded by the pressing of the abutting protrusion 123, thereby forming a seal. In addition, the abutting protrusion 123 presses the water outlet end of the water outlet pipe 140 onto the bottle cap body 110 and bends again to form a similar Z-shaped bend. In the above-mentioned sealing process, on the one hand, a primary seal is formed by the bending of the water outlet pipe 140 at the concave part, and on the other hand, a primary seal is formed by the extrusion of the abutting protrusion 123 and the bottle cap body 110. Thereby improving the sealing effect of the water outlet pipe 140.

[0056] refer to Figure 4 As shown in , for the convenience of description, the water outlet pipe 140 is divided into two sections with the inner concave structure 144 as a reference point, namely the first water outlet section 141 and the second water outlet section 142, wherein the water outlet end of the water outlet pipe 140 is located at the first water outlet section 141, and the second water outlet section 142 is connected to the bottle cap body 110. Figure 3 When the water outlet pipe 140 is unfolded, the first water outlet section 141 and the second water outlet section 142 are inclined relative to the axis of the bottle cap body 110 and away from the rotation axis (axis L1), which is convenient for children to drink and also convenient for the protrusion to press the first water outlet section 141 to bend. Figure 4As shown, when the water outlet pipe 140 is sealed, the first water outlet section 141 and the second water outlet section 142 are folded to achieve sealing. In addition, the abutting protrusion 123 also presses against the first water outlet section 141 to bend it, and through the extrusion between the abutting protrusion 123 and the bottle cap body 110, a secondary seal is added.

[0057] In an alternative embodiment, a sealing protrusion 143 is further provided inside the water outlet pipe 140. The sealing protrusion 143 is used to seal the folded portion of the water outlet pipe 140 to enhance the sealing effect. Exemplarily, the sealing protrusion 143 is located on the inner wall of the water outlet pipe 140 near the rotation axis. When the first water outlet section 141 is folded relative to the second water outlet section 142, the sealing protrusion 143 abuts against the opposite side walls, thereby further increasing the sealing effect.

[0058] It should be understood that the above-mentioned abutting protrusion 123 and the sealing post 122 and the flip cover 120 may be of an integral structure, or the abutting protrusion 123 and the sealing post 122 and the flip cover 120 are of a split structure, and the abutting protrusion 123 and the sealing post 122 can be fixed to the flip cover 120 by bonding.

[0059] In addition, when the flip cover 120 seals the ventilation hole 130 and the water outlet pipe 140, the height of the folded portion of the first water outlet section 141 and the second water outlet section 142 is higher than the height of the ventilation hole 130, that is, the height of the sealing position of the water outlet pipe 140 is higher than the height of the sealing position of the ventilation hole 130. Therefore, when the flip cover 120 is rotated and opened, even if the ventilation hole 130 is closer to the rotation axis relative to the water outlet pipe 140, due to the difference in their sealing heights, it can still be ensured that the ventilation hole 130 contacts the seal first, and then the water outlet pipe 140 contacts the seal.

[0060] Refer to together Figure 4 、 Figure 5 and Figure 6 , Figures 4 to 6 shows a schematic diagram of the flip cover 120 rotating from the closed state to the open state in the counterclockwise direction. During the opening process, the flip cover 120 rotates along the Figures 4 to 6 direction shown by the arrowed arc exemplified in Figure 5 shows a schematic diagram of the open state of the flip cover 120; Figure 6 shows a schematic diagram of the fully open state of the flip cover 120.

[0061] First refer to Figure 4 shown. In the state where the flip cover 120 is closed, the sealing post 122 and the abutting protrusion 123 of the flip cover 120 respectively seal the ventilation hole 130 and the water outlet pipe 140. Then, the flip cover 120 is opened, and the flip cover 120 rotates counterclockwise to first release the seal of the ventilation hole 130, and the high-pressure gas in the bottle body 200 can leak out through the ventilation hole 130. At this time, the water outlet pipe 140 is still in a sealed state. Continue to rotate the flip cover 120 toFigure 5 In the state shown, the water outlet pipe 140 is also unsealed. In this state, children can use the water outlet pipe 140 to drink beverages. Figure 5 In the state shown, there is no limit, and the flip cover 120 is very likely to hit a child. Therefore, in the bottle cap 100 provided in the embodiment of the present application, a limit is added to the flip cover 120. Figure 6 As shown, the flip cover 120 provided in the embodiment of the present application can also be locked in the fourth setting position. When the flip cover 120 is in the fourth setting position, the flip cover 120 abuts against the bottle cap body 110, and the position where the flip cover 120 abuts against the bottle cap body 110 is located on the side of the rotating shaft away from the water outlet pipe 140. That is, Figure 6 In the state shown, when the flip cover 120 is locked to the fourth setting position, the flip cover 120 abuts against the bottle cap body 110 .

[0062] For the convenience of describing the state of the flip cover 120, the outer side 125 of the flip cover 120 is defined, and the outer side 125 refers to the side of the flip cover 120 exposed when the flip cover 120 is covered on the bottle cap body 110. That is, the pressing protrusion for pressing the water outlet pipe 140 is arranged on the inner side of the flip cover 120, and the side of the flip cover 120 away from the abutting protrusion 123 is the outer side 125.

[0063] For reference Figures 4 to 6 A connecting protrusion 113 is provided on the bottle cap body 110, and the connecting protrusion 113 is used for rotationally cooperating with the flip cover 120. Specifically, the rotating shaft is fixedly connected to the flip cover 120 and inserted into the connecting protrusion 113 to be rotationally connected with the connecting protrusion 113, thereby realizing the rotational cooperation between the flip cover 120 and the bottle cap body 110.

[0064] When the flip cover 120 is locked to the fourth setting position, a limiting protrusion 114 is provided on the forehead side of the connecting protrusion 113 away from the vent hole 130, and the limiting protrusion 114 protrudes outside the connecting protrusion 113. When the flip cover 120 is rotated to the fourth setting position, the limiting protrusion 114 abuts against the flip cover 120, and the outer side surface 125 of the flip cover 120 abuts against the bottle cap body 110, that is, the limiting protrusion 114 and the bottle cap body 110 jointly lock the flip cover 120. In this state, the flip cover 120 can be fixed, and the flip cover 120 can be kept in the fourth setting position even if the bottle body 200 is rotated, thereby improving the safety of children when using the bottle cap 100.

[0065] For reference Figure 3 and Figure 6, to ensure the stability of the flip cover 120 during rotation and locking. When the flip cover 120 is rotatably connected to the bottle cap body 110, two support feet 126 are provided at one end of the flip cover 120 close to the connecting protrusion 113. The two support feet 126 are located on opposite sides of the connecting protrusion 113, that is, the two support feet 126 are arranged along the axis direction of the rotating shaft, and the limiting protrusion 114 is clamped between the two support feet 126. The rotating shaft is a cylindrical structure provided on each support foot 126, and this cylindrical structure is rotatably connected to the connecting protrusion 113. During assembly, connecting holes are respectively provided on opposite sides of the connecting protrusion 113, and the two cylindrical structures are respectively inserted into the corresponding connecting holes and can rotate within the connecting holes, thereby realizing the rotation of the flip cover 120 relative to the bottle cap body 110.

[0066] When cooperating with the limiting protrusion 114, one end of the flip cover 120 close to the limiting protrusion 114 is the pressing end 124, and the pressing end 124 is located between the two support feet 126, so that when pressing, the stability of the flip cover 120 can be increased through the two support feet 126.

[0067] In an alternative solution, the pressing end 124 of the flip cover 120 is thinned, that is, the thickness of the pressing end 124 is less than the thickness of other parts, so that when the pressing end 124 is engaged with the limiting protrusion 114, it can elastically deform to cross the limiting protrusion 114.

[0068] The embodiment of the present application also provides a drinking bottle, which includes a bottle body 200 and the bottle cap 100 of any one of the above, wherein the bottle cap 100 is hermetically connected to the bottle body 200.

[0069] In the above technical solution, by arranging the ventilation holes 130 on the side of the water outlet pipe 140 facing the rotating shaft, the ventilation holes 130 are closer to the rotating shaft relative to the water outlet pipe 140. When the flip cover 120 is opened, the ventilation holes 130 can be unsealed prior to the water outlet pipe 140, so that the air pressure inside the drinking bottle can be adjusted as soon as possible through the ventilation holes 130, reducing the water spraying situation of the water outlet pipe 140 after unsealing, and improving the use effect of the drinking bottle.
