Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1 to 7This invention provides a technical solution: a combined safety bottle cap, comprising a cap body 1 and a bottle body 10. The cap body 1 is threaded onto the open end of the bottle body 10. A mutually cooperating disposable safety structure is provided between the cap body 1 and the bottle body 10. A tea caddy 2 is fixedly fixed downwards from the middle of the cap body 1. A tea extraction device is installed inside the tea caddy 2. A cap 11 is installed on the tea caddy 2 below the tea extraction device. A wire mesh is installed in the middle of the cap 11. A partition 3 is fixed inside the tea caddy 2. The tea caddy above the partition 3 is... Inside the cylinder 2, a rotating cover 4 is installed. The side wall of the tea container 2 below the partition 3 is evenly provided with mesh. When filling the tea container, first open the cylinder cover 11, put the tea into the tea container 2, and then tighten the cylinder cover 11 to install it at the bottom of the tea container 2. The top of the bottle cap body 1 is equipped with a suction nozzle 6. The input end of the suction nozzle 6 extends to the bottom of the bottle cap body 1 and is sealed with a hose 7. The end of the hose 7 away from the suction nozzle 6 is equipped with a heat-resistant filter housing 8. The heat-resistant filter housing 8 is made of 316 or 304 stainless steel, which is safe, non-toxic, and has good thermal conductivity.

[0029] like Figure 1 and Figure 7 As shown, the disposable safety structure includes a protrusion 1001 fixed to the top of the outer wall of the bottle cap body 1. A slot 102 is provided at the bottom of the side wall of the bottle cap body 1 for the protrusion 1001 to be screwed into. A safety block 17 is rotatably installed on the bottle cap body 1 on the side wall of the slot 102. One end of the safety block 17 is connected to a release strip 171 used to block the protrusion 1001. A one-way receiving groove 1021 is provided on the side wall of the bottle cap body 1 for the release strip 171 to enter. The one-way receiving groove 1021 is located above the safety block 17. A threaded ring 1 is provided on the inner side of the side wall of the bottle cap body 1. A threaded ring 2 that matches the threaded ring 1 is provided on the outer side wall of the open end of the bottle body 10. The protrusion 1001 is located below the threaded ring 2. The slot 102 is located below the threaded ring 1. Therefore, the disposable safety structure will not affect the stability of the threaded connection between the bottle cap body 1 and the bottle body 10.

[0030] After the staff prepares the beverage, they screw the bottle cap body 1 onto the bottle body 10 and tighten it, causing the protrusion 1001 to screw into the slot 102. During this process, the protrusion 1001 will push the release strip 171 into the one-way receiving groove 1021. When the bottle cap body 1 is tightened in place, the release strip 171 will automatically unscrew from the one-way receiving groove 1021 due to gravity, blocking the protrusion 1001 and preventing it from unscrewing. If the bottle cap body 1 is forcibly unscrewed from the bottle body 10, the release strip 171 will definitely break. Customers can tell whether the bottle cap body 1 has been opened a second time based on the condition of the release strip 171, which provides good security.

[0031] like Figure 2 and Figure 6As shown, the tea extraction device includes a central shaft 12, the top of which is fixedly connected to the rotating cover 4. Paddles 121 are evenly arranged on the central shaft 12 inside the tea cylinder 2 below the partition 3. When the rotating cover 4 rotates, it will drive the central shaft 12 to rotate synchronously. The paddles 121 continuously stir the tea ingredients such as tea leaves and ginseng slices in the tea cylinder 2, accelerating the release of tea ingredients and making the beverage in the bottle 10 have a better flavor.

[0032] like Figure 3 As shown, the tea extraction device includes a threaded rod 13, the top of which is fixedly connected to the rotating cover 4. A pressure plate 15 is threadedly connected to the threaded rod 13 inside the tea cylinder 2 below the partition 3. The lower end face of the pressure plate 15 is evenly provided with spikes 151. A guide rod 14 is fixed on the partition 3. A guide hole is provided on the pressure plate 15 for the guide rod 14 to pass through. When the rotating cover 4 rotates, it will drive the threaded rod 13 to rotate synchronously, so that the pressure plate 15 moves along the guide rod 14. When the pressure plate 15 moves downward, it will continuously squeeze the tea ingredients such as fresh lemon, orange, and raspberry. The spikes 151 will puncture the tea ingredients, accelerate the release of tea ingredients, and make the beverage in the bottle 10 taste better.

[0033] like Figure 5 and Figure 6 As shown, fixed grid holes 201 are evenly spaced on the side wall of the tea container 2 above the partition 3. The outer side wall of the rotating cover 4 is in contact with the inner side wall of the tea container 2. Moving grid holes 402 are evenly spaced on the side wall of the rotating cover 4. Exhaust holes 401 are evenly spaced on the top wall of the rotating cover 4. When the rotating cover 4 is rotated, the moving grid holes 402 and the fixed grid holes 201 are aligned. The hot air in the bottle 10 will be released outward in sequence through the fixed grid holes 201, the moving grid holes 402, and the exhaust holes 401. A rubber gasket 403 is glued to the outer side wall of the rotating cover 4 between two adjacent moving grid holes 402. When the rotating cover 4 is rotated so that the rubber gasket 403 and the fixed grid holes 201 are aligned, the rubber gasket 403 and the fixed grid holes 201 are tightly fitted together, which has good sealing performance and reduces the possibility of tea spillage. It also has a heat preservation effect.

[0034] like Figure 1 and Figure 5 As shown, a handle 5 is fixed in the middle of the top of the rotating cover 4. The handle 5 makes it easier to rotate the rotating cover 4.

[0035] A sealing cap ring 101 is bonded to the upper end face of the bottle cap body 1, and a milled groove for the sealing cap ring 101 to be embedded is provided on the edge of the upper end face of the rotating cap 4. The above structure improves the heat preservation performance of this device.

[0036] like Figure 4As shown, the anti-scalding filter housing 8 is a hollow cylinder. Filter holes 801 are evenly distributed on the side wall of the anti-scalding filter housing 8 near the hose 7. A piston block 9 is installed inside the anti-scalding filter housing 8 to seal the filter holes 801. The piston block 9 and the bottom wall of the anti-scalding filter housing 8 are fixedly connected by several temperature control springs 16. In this device, when the temperature of the beverage in the bottle 10 exceeds the preset value (i.e., the water temperature that a normal person can drink), the temperature control springs 16 will immediately extend, driving the piston block 9 to move and block the filter holes 801, preventing the beverage in the bottle 10 from entering the anti-scalding filter housing 8. When the temperature is lower than the preset value, the temperature control springs 16 will return to normal, so that the filter holes 801 are no longer blocked by the piston block 9, allowing the beverage in the bottle 10 to enter the anti-scalding filter housing 8 through the filter holes 801, and finally be consumed by people through the hose 7 and the spout 6.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
