DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figure 1-5As shown, a rotary lock type ball cover includes a ball 1, a first cover body 2 and a second cover body 3. The upper end of the first cover body 1 is provided with a ball groove 207, and the bottom of the ball groove 207 is provided with a first liquid outlet 201. The first cover body 2 and the second cover body 3 are rotatably connected. A first annular baffle 206 extending downward is provided in the first cover body 1. A first liquid outlet pipe 205 communicating with the first liquid outlet 201 is provided in the first annular baffle 206. A first notch 206 is provided on the wall of the first liquid outlet pipe 205. 03. A first annular groove 310 is provided on the top of the second cover body 3, and an upwardly extending second annular baffle 305 is provided on the bottom end surface 311 of the first annular groove 310. A second liquid outlet pipe 306 is provided in the second annular baffle 305, and a second notch 303 that cooperates with the first notch 203 is provided on the tube wall of the second liquid outlet pipe 306. A second liquid outlet hole 302 is provided in the area of the bottom end surface 311 located between the outer wall of the second liquid outlet pipe 306 and the inner wall of the second annular baffle 305.

[0018] Specifically, the second annular baffle 305 is inserted into the first annular baffle 206, and the second annular baffle 305 and the first annular baffle 206 are interference fit. The second liquid outlet pipe 306 is inserted into the first liquid outlet pipe 205, and the second liquid outlet pipe 306 and the first liquid outlet pipe 205 are interference fit. The outer wall of the first liquid outlet pipe 205, the second annular baffle 305 and the bottom end face 311 constitute a cavity. The liquid in the bottle flows through the second liquid outlet hole 302 flow channel cavity. When the first notch 203 and the second notch 303 are connected, the liquid can flow to the first liquid outlet hole 201. When the first notch 203 and the second notch 303 are not connected, the liquid cannot flow to the first liquid outlet hole 201, thereby realizing the sealing effect of the ball cover.

[0019] Furthermore, a first rib 204 and a second rib 209 are provided on the inner end surface of the first cover body 2, and the first rib 204 and the second rib 209 are symmetrically distributed on both sides of the first annular baffle 206, and the first rib 204, the second rib 209 and the first notch 203 are located on the same horizontal straight line, and a third rib 304 and a fourth rib 309 are provided on the outer end surface of the second cover body 3, and the third rib 304 and the fourth rib 309 are symmetrically distributed on both sides of the second annular baffle 305, and the third rib 304, the fourth rib 309 and the second notch 303 are located on the same horizontal straight line. When opening, the first cover body 2 is rotated, and when the first notch 203 and the second notch 303 are connected to each other, the first rib 204 contacts the third rib 304, and the second rib 209 contacts the fourth rib 309; when closing, the first cover body 2 is rotated, and when the first notch 203 and the second notch 303 are separated and on the same horizontal line, the first rib 204 contacts the fourth rib 309, and the second rib 209 contacts the fourth rib 304. The effect of this design is that when the first cover body 2 is rotated to open or close, the moment the first rib 204 and the second rib 209 contact the third rib 304 and the fourth rib 309, the user will clearly feel the increase in the resistance of the rotating cover body, and the contact between the ribs will also make a collision sound, thereby allowing the user to perceive that the cover body is opened or closed.

[0020] Furthermore, a second annular groove 202 is provided on the inner wall of the first cover 2, and a boss 301 is provided on the outer wall of the second cover 2 on the side closest to the ball 1, which cooperates with the second annular groove 202. This arrangement is used to enable the first cover 2 and the second cover 3 to be assembled and rotated relative to each other. Alternatively, the boss can be provided on the first cover 2 and the groove can be provided on the second cover 3 to similarly achieve the functions of assembling and rotating the first and second covers 2 and 3.

[0021] Furthermore, an internal thread 307 is provided on the inner wall of the second cover body 2 away from the ball 1. This setting is used for the ball cover to cooperate with the bottle mouth. The specific size of the internal thread 307 can be set according to the size of the bottle mouth thread.

[0022] Furthermore, the first cover 2 is provided with an indicator mark 208, and the second cover 3 is provided with a switch mark 308 for use with the indicator mark 208. The indicator mark 208 is provided on the outer wall of the first cover 2 on the same side as the first notch 203, and the switch mark 308 includes the characters "ON" and "OFF", wherein the character "ON" of the switch mark 308 is provided on the outer wall of the second cover 3 on the same side as the second notch 303, and the character "OFF" of the switch mark 308 is provided on the outer wall of the second cover 3 away from the second notch 303. When the indicator mark 208 points to "ON", the first notch 203 and the second notch 303 are connected, thereby opening the bottle cap. When the indicator mark 208 points to "OFF", the first notch 203 and the second notch 303 are disconnected, thereby closing the bottle cap.

[0023] Furthermore, the number of the second liquid outlet holes 302 is two, and the two second liquid outlet holes 302 are symmetrically distributed on both sides of the second annular baffle 305. Of course, multiple second liquid outlet holes or liquid outlet grooves can be set according to the viscosity of the liquid and the requirements for the liquid outlet speed.

[0024] Working principle:

[0025] When opening, the indicator mark 208 of the first cover body 2 is rotated to align with the character "ON" on the switch mark 308. At this time, the first notch 203 and the second notch 303 are connected, and the first liquid outlet pipe 205 and the second liquid outlet pipe 306 are in a connected state. The liquid in the bottle can flow through the second liquid outlet hole 302 to the first notch 203 and the second notch 303, and finally flow from the first liquid outlet hole 201 to the ball 1. At this time, the ball 1 can be rolled to achieve the purpose of liquid discharge;

[0026] When closing, the first cover 2 is rotated to align the indicator mark 208 with the character "OFF" on the switch mark 308. At this time, the first notch 203 and the second notch 303 are not connected, so the liquid cannot flow to the ball 1, thereby achieving the function of sealing and leak-proofing the bottle cap.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
