The following describes the specific implementation of the present invention in more detail with reference to specific embodiments:

fig. 1 to 6 illustrate a bottle cap 1 according to an embodiment of the present invention, which is covered on a bottle mouth of a bottle body filled with liquid, and is used for sealing or unsealing the bottle body, so that the liquid in the bottle body can be poured out or sprayed out.

As shown in fig. 1 to 3, the bottle cap 1 includes a lower cap 2, an upper cap 3, a first adapter 4, a second adapter 5, a spray head 6, a valve tube 7, and a valve member 8;

the lower cover 2 is used for covering the bottle mouth of the bottle body;

the upper cover 3 is movably sleeved outside the lower cover 2 and can move along the axial direction of the lower cover 2, namely the upper cover 3 moves close to or away from the lower cover 2;

the first adapter 4 is fixedly arranged on the top surface of the lower cover 2 and is arranged towards the upper cover 3;

the second joint pipe 5 is fixedly arranged on the upper cover 3, is arranged towards the lower cover 2, is inserted into the first joint pipe 4 and is communicated with the first joint pipe 4;

the spray head 6 is sleeved at the end part of the second pair of connecting pipes 5 far away from the lower cover 2, is communicated with the second pair of connecting pipes 5 and is used for spraying liquid at a high speed so as to achieve different liquid outlet effects;

the valve tube 7 is fixedly arranged on the lower cover 2, the valve tube 7 is oppositely arranged on two sides of the lower cover 2 at the first connecting pipe 4, the valve tube 7 is communicated with the first connecting pipe 4, namely the first connecting pipe 4 is arranged towards the upper cover 3 and is used for being communicated with the second connecting pipe 5, and the valve tube 7 is arranged towards the bottle body and is used for being communicated with liquid in the bottle body;

a valve element 8 is movably arranged between the first connecting pipe pair 4 and the valve pipe 7, and the valve element 8 is used for sealing or unsealing a connection between the second connecting pipe pair 5 and the valve pipe 4 along with the movement of the second connecting pipe pair 5, namely the valve element 8 is used for communicating the first connecting pipe pair 4 with the valve pipe 7 or blocking the communication between the first connecting pipe pair 4 and the valve pipe 7.

The working principle of the bottle cap 1 of the present embodiment is as follows:

a user rotates or presses the upper cover 3 to enable the upper cover 3 to be close to the lower cover 2, the second pair of connecting pipes 5 fixedly arranged on the upper cover 3 are close to the valve piece 8, finally the valve piece 8 is pushed away from the connecting position between the first pair of connecting pipes 4 and the valve pipe 7, the isolation between the first pair of connecting pipes 4 and the valve pipe 7 is unsealed, and liquid in the bottle body can enter the first pair of connecting pipes 4 from the valve pipe 7 and then enter the second pair of connecting pipes 5 to be sprayed out from the spray head 6 communicated with the second pair of connecting pipes 5; the user makes the upper cover 3 keep away from the lower cover 2, the second connecting pipe pair 5 fixedly arranged on the upper cover 3 keeps away from the valve member 8, and finally the valve member 8 is restored between the first connecting pipe pair 4 and the valve pipe 7 and is sealed between the first connecting pipe pair 4 and the valve pipe 7, and the liquid in the bottle body is not sprayed out any more.

Meanwhile, as shown in fig. 4, the cross section of the end 59 of the second pair of connecting pipes 5 contacting the valve element 8 is polygonal, which is different from the shape of the valve element 8, that is, the end of the second pair of connecting pipes 5 is dislocated from the valve element 8 when contacting, so as to avoid the end of the second pair of connecting pipes 5 being blocked by the valve element 8 when pushing the valve element 8, and the liquid in the valve pipe 7 can not enter the second pair of connecting pipes 5.

In addition, when the valve member 8 seals the connection between the first connecting pipe pair 4 and the valve pipe 7, most of the valve member 8 is accommodated in the valve pipe 7, and a small part of the valve member 8 is exposed out of the first connecting pipe pair 4, so that the second connecting pipe pair 5 can push the valve member 8.

Different liquids are used in different ways, common liquid is filled in the bottle body, when a user unseals the space between the first connecting pipe 4 and the valve pipe 7, the bottle body needs to be inverted or forcibly squeezed, and the liquid can be sprayed out from the spray head 6; the liquid in a high-pressure state is filled in the bottle body, when the space between the first butt joint pipe 4 and the valve pipe 7 is unsealed, the pressure of the liquid is released, and the liquid can be automatically sprayed out from the spray head 6; the bottle cap 1 of the embodiment can be used for bottle bodies of different types of liquid, such as carbonated beverage, because the carbonated beverage is dissolved with carbon dioxide, namely the carbonated beverage has pressure, when the space between the first connecting pipe 4 and the valve pipe 7 is unsealed, the beverage is sprayed out from the spray head 6, and a user can drink the beverage without contacting with a bottle opening; for example, the mineral water with pressure can be sprayed from the nozzle 6 to maintain the unsealing state between the unsealing first butt joint pipe 4 and the valve pipe 7, so that the user can drink directly, or the mineral water is sprayed in a mist form to humidify the environment of the place, or the mineral water is sprayed directly on the face of the user to moisturize the user.

The beneficial effect of bottle lid 1 and bottle that this embodiment provided lies in:

the bottle cap 1 for sealing the bottle body is divided into an upper cap 3 and a lower cap 2, and the upper cap 3 is movably sleeved on the lower cap 2 to achieve the effect of opening or closing the bottle body, so that the bottle cap is convenient for a user to use; move upper cover 3 down 2 directions of lower cover, it removes to drive second butt joint pipe 5, push up the valve member 8 of sealing between first butt joint pipe 4 and valve pipe 7, bottle lid 1 is the open mode, liquid in the bottle can be poured or spout, the user need not to open bottle lid 1 completely and can use the liquid in the bottle, facilitate the use and can prevent to open bottle lid 1 after losing, and liquid pours or spouts from shower nozzle 6, its play liquid mode is different with directly opening bottle lid 1 and pours liquid, the liquid measure of can effectively controlling.
