[0035] The following further describes the present application in detail with reference to the accompanying Figures 1-4 drawings.

[0036] An embodiment of the present application discloses a simple solid-liquid separation bottle cap structure.

[0037] Referring to Figure 1 , a simple solid-liquid separation bottle cap structure includes a bottle body 1, a lower cover body 2, and an upper cover body 3. The structure of the bottle body 1 is the same as that of the prior art. An external thread is provided on the outer side wall of the bottle mouth of the bottle body 1. The lower cover body 2 is threadedly connected to the bottle body 1, and the upper cover body 3 is threadedly connected to the lower cover body 2. It is defined that the axial direction of the bottle body 1 is the vertical direction, and the upper cover body 3 is above the overall bottle cap structure.

[0038] Referring to Figure 2 , the lower cover body 2 includes a connection portion 21 threadedly connected to the bottle body 1, a sealing tube 22 inserted into the bottle body 1, a protective ring portion 23 located outside the connection portion 21, and a sealing portion 24 for cooperating and connecting with the upper cover body 3. The connection portion 21, the protective ring portion 23, and the sealing portion 24 are integrally formed.

[0039] Referring to Figure 3 , the upper cover body 3 includes a receiving tube 31 inserted into the sealing tube 22 and used for storing a solid medium, and a driving portion 32 located outside the receiving tube 31 and connected to the sealing portion 24. The receiving tube 31 and the driving portion 32 are integrally formed. Its end facing the lower cover is in an open state, and the overall axial length of the receiving tube 31 is greater than the axial length of the driving portion 32.

[0040] Referring to Figure 2 , Figure 3 and Figure 4 , the driving portion 32 is threadedly connected to the sealing portion 24. A first sealing ring 321 is integrally provided on the inner side wall of the driving portion 32 facing the lower cover body 2, and the first sealing ring 321 is in sealing contact with the sealing portion 24. Among them, the lower cover body 2 also has a first positioning surface 25 for the end surface of the driving portion 32 to abut against. The top of the upper cover body 3 is integrally convex outward in an arc shape.

[0041] The receiving tube 31 and the sealing tube 22 are coaxially arranged and are in sealing contact with each other. The end of the receiving tube 31 has an inwardly contracting inward portion 311, and a guiding flared opening 221 for the receiving tube 31 to be inserted is provided at the top opening of the sealing tube 22. Through the arrangement of the inward portion 311 and the guiding flared opening 221, the insertion of the receiving tube 31 and the sealing tube 22 is more convenient.

[0042] The end of the receiving tube 31 abuts against the bottom of the sealing tube 22. A plurality of communication holes 222 are circumferentially formed in the bottom side wall of the bottom of the sealing tube 22. In the normal storage state, the communication holes 222 communicate the bottle body 1 and the sealing tube 22. When in use, when the receiving tube 31 axially rises, the communication holes 222 communicate the bottle body 1 and the receiving tube 31, so that the solid medium can enter the bottle body 1 through the communication holes 222 to achieve solid-liquid mixing. In this embodiment, the sealing tube 22 has six communication holes 222, and the six communication holes 222 are circumferentially and evenly arranged at intervals along the axial direction.

[0043] A guiding portion 223 for solid material feeding is further provided at the bottom of the inner cavity of the sealing tube 22. The guiding portion 223 is integrally columnar, and a downwardly inclined guiding conical surface 2231 is arranged on the top end surface thereof, so that after the bottle body 1 and the receiving tube 31 are communicated, the solid slides out of the communication hole 222 along the guiding conical surface 2231 under the action of gravity.

[0044] A second sealing ring 2232 is integrally arranged on the outer side wall of the guiding portion 223 in the circumferential direction, and the second sealing ring 2232 abuts against the inner wall of the receiving tube 31. A plurality of third sealing rings 312 are integrally arranged on the outer side wall of the receiving tube 31 in the circumferential direction, and the third sealing rings 312 are arranged at intervals along the axis. After the receiving tube 31 and the sealing tube 22 are hermetically abutted, the third sealing rings 312 are located between the guiding flared portion 221 and the communication holes 222. Through the second sealing ring 2232 and the third sealing rings 312, double sealing of the inner and outer side walls of the receiving tube 31 is achieved, reducing the influence of external air impurities on the solid medium.

[0045] The connecting portion 21 is threadedly connected to the bottle mouth of the bottle body 1. A sealing abutting ring 26 that abuts against the inner wall of the bottle mouth is integrally arranged between the lower cover body 2 and the sealing tube 22. The bottom of the outer side wall of the sealing abutting ring 26 has an inclined ring surface 261 to facilitate the insertion of the sealing abutting ring 26 and the bottle mouth. The sealing abutting ring 26 is press-fitted into the inner wall of the bottle mouth, and the connecting portion 21 and the outer wall of the bottle mouth are threadedly sealed, realizing double sealing of the lower cover body 2 and the bottle body 1, and the sealing effect is relatively ideal.

[0046] The protective ring portion 23 is located outside the connecting portion 21 and is integrally annular and inclined inwardly towards the upper cover body 3. The bottle body 1 has a second positioning surface 11 for the end of the protective ring portion 23 to abut against. The protective ring portion 23 covers the connecting portion 21, ensuring the connection stability between the lower cover body 2 and the bottle body 1. At the same time, in order to improve the overall structural strength of the lower cover body 2, a reinforcing piece 27 is further connected between the protective ring portion 23 and the connecting portion 21, and the reinforcing pieces 27 are arranged at intervals along the axis in the circumferential direction. In this embodiment, the lower cover body 2 has four reinforcing pieces 27 that are circumferentially and evenly arranged at intervals.

[0047] The implementation principle of a simple solid-liquid separation bottle cap structure in an embodiment of the present application is as follows: First, place the solid medium into the receiving tube 31, and then realize the connection of the upper and lower caps 2 through the threaded cooperation of the driving part 32 and the sealing part 24. After that, connect and fix the assembled upper and lower caps 2 and the bottle body 1;

[0048] When only drinking the liquid in the bottle body 1, rotate the protective ring part 23 to remove the lower cap 2 and the upper cap 3 from the bottle body 1 at the same time; when solid-liquid mixing is required, rotate the driving part 32 to move the receiving tube 31 away from the guiding part 223, and communicate the bottle body 1 and the receiving tube 31 with each other through the communication hole 222, and the solid medium is released into the bottle body 1 along the guiding conical surface 2231.

[0049] The above are all the preferred embodiments of the present application. Without restricting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
