The aroma of the cigarette can enter the water through the second gap and then enter the oral cavity.

[0036] Referring to Figs. 3 and 4, the cap body 110 includes a top wall that is substantially circular and a sidewall that is enclosed around an outer periphery of the top wall. The sidewall is adapted to be enclosed to the mouth of the water bottle. For example, an inner side of the sidewall is provided with an internal thread for threadedly connecting to the mouth of the water bottle. The top portion of the cap body 110 can be understood as the outer side of the top wall of the cap body 110 protruding the annular protrusion 120. The annular protrusion 120 is arranged around a central axis of the cap body 110. The annular protrusion 120 is arranged close to the central axis of the cap body 110 relative to the sidewall. The annular protrusion 120 and the top wall of the cap body 110 form the storage groove 130 for accommodating the cigarette.

[0037] Referring to Fig. 3, the straw 140 that penetrates through the top portion of the cap body 110 is arranged in the storage groove 130. For example, the straw 140 is arranged at a middle position of the annular protrusion 120. The bottom end of the straw 140 is connected to the top wall of the cap body 110. The straw 140 penetrates through the top wall of the cap body 110, so that the water in the water bottle can be sucked out through the straw 140.

[0038] Exemplarily, the incense stick is stored in the storage tank 130, and the incense stick in the bottle cap is not dissolved in water as a solvent to generate a fragrance flavor, but the protruding suction nozzle 220 of the outer cap structure 200 is sucked by the human mouth, so that the negative pressure generated in the straw drives the fragrance of the incense stick to enter the water from the second gap, so as to enter the oral cavity, so that the human obtains the fragrance perception. The incense stick of the embodiment of the disclosure is directly embedded in the product, and the incense stick of the product of the related art is generally arranged in a separate incense ring.

[0039] Referring to FIG. 3, exemplarily, the height of the straw 140 is greater than the height of the annular protrusion 120, that is, the distance of the straw 140 relative to the top of the cap main body 110 is greater than the distance of the annular protrusion 120 relative to the cap main body 110, and the top of the straw 140 is protrudingly arranged relative to the top of the annular protrusion 120. The side wall of the straw 140 is provided with a gas guide hole 141 communicating with the straw 140. The gas guide hole 141 can guide air into the bottle to balance the air pressure. The specific position of the gas guide hole 141 is not limited here, and the size and shape of the gas guide hole 141 can be set according to actual use requirements.

[0040] Referring to FIG. 1, exemplarily, the outer cap structure 200 is sealingly connected with the annular protrusion 120, and the outer cap structure 200 sealingly arranges the storage tank 130. The outer cap structure 200 covers the top of the cap main body 110, and the outer cap structure 200 covers and seals the storage tank 130, and the gas guide hole 141 is located in the sealed space formed by the outer cap structure 200 and the storage tank, and the gas guide hole 141 can guide air into the bottle to balance the air pressure. The outer cap structure 200 is provided with a first through hole 210, and the first through hole 210 communicates the storage tank 130 with the outside air.

[0041] After the bottle cap of the embodiment of the disclosure is drunk into the bottle body, the volume of the bottle body loses water and shrinks when the water is drunk, and air needs to be provided to fill the shrunk volume. Compared with the odor water bottle of the related art which provides the flow of air into the bottle body through the hole on the outside to balance the pressure in the bottle, the gas guide hole 141 of the embodiment of the disclosure can reduce the problem of water leakage and has better air tightness when the product is used.

[0042] When drinking water, the bottle cap is connected with the water bottle opening of the water bottle containing mineral water, the water bottle is inclined to a suitable angle, the water in the water bottle flows into the straw 140, the protruding suction nozzle 220 is sucked by the human mouth, at this time, the negative pressure is generated in the straw 140, the air enters the storage tank 130 from the first through hole 210, and the smell of the incense stick enters the water being drunk from the second gap, the fragrance molecules enter the water together with the flowing water and enter the oral cavity, the human body perceives the fragrance molecules through the postnasal olfaction, obtains the fragrance perception, and the water drunk into the stomach is still clear water, so that the odor of the bottled mineral water product is increased and the health value of not ingesting sugar is achieved.

[0043] The bottle cap of the embodiment of the present disclosure comprises a middle cap structure 100 and an outer cap structure 200. The middle cap structure 100 comprises a cap body 110 which is connected with the bottle mouth of a water bottle. The top of the cap body 110 is provided with an annular protrusion 120. The annular protrusion 120 and the cap body 110 form a storage groove 130 for accommodating a flavor stick. A straw 140 which penetrates through the top of the cap body 110 is arranged in the storage groove 130. The height of the straw 140 is greater than the height of the annular protrusion 120. A gas guide hole 141 which communicates with the straw 140 is arranged on the sidewall of the straw 140. The gas guide hole 141 can guide air into the bottle to balance the air pressure. The outer cap structure 200 is sealingly connected with the annular protrusion 120. The outer cap structure 200 sealingly arranges the storage groove 130. The outer cap structure 200 is provided with a first through hole 210 which communicates with air. The outer cap structure 200 comprises a protruding straw 220. The straw 140 is inserted into the protruding straw 220. A second gap is formed between the sidewall of the protruding straw 220 and the sidewall of the straw 140. The flavor of the flavor stick can enter the water through the second gap and then enter the oral cavity. The bottle cap can be threadedly connected with the bottle mouth of the water bottle. By tilting the water bottle to a suitable angle, the water in the bottle flows into the straw 140. Sucking the protruding straw 220 with the mouth of a person can cause negative pressure in the straw 140. Air enters the storage groove 130 from the first through hole 210. The flowing water can drive the flavor molecules of the flavor stick to enter the oral cavity through the second gap by negative pressure. The human body can perceive the flavor molecules through the postnasal olfaction and obtain the flavor perception. At the same time, the water drunk into the stomach is still clean water. The bottle cap realizes the flavoring of bottled mineral water products and the health value of not ingesting sugar. Further, the bottle cap can be conveniently carried and can be adapted to different mineral water bottles, realizing the convenience of outdoor carrying and use.

[0044] The bottle cap of the embodiment of the present disclosure can be directly applied to the existing mineral water bottle to flavor the mineral water. Compared with the existing odor water bottle, the flavor stick and related components are integrated in the bottle cap, which is convenient to carry, does not need to carry the water bottle and water, reduces the weight of the user, and the user can purchase bottled mineral water in a store for combined use when he wants to drink odor beverage, greatly reducing the burden of the user. Moreover, compared with the form that the flavor stick of the odor water bottle is separated from the water bottle structure, the integration degree of the bottle cap of the embodiment of the present disclosure is higher. There is no independent flavor ring structure. The flavor stick is directly embedded in the bottle cap. The structure is more compact. The amount of consumables used for injection molding is reduced. Compared with the odor water bottle product, the bottle cap of the embodiment of the present disclosure removes the straw and the air inlet hole in the bottle. The product form is more simple. At the same time, since there is no air inlet hole in the bottle, the water leakage problem of the product can be reduced.

[0045] Fig. 7 is a schematic diagram of a dust cover according to an embodiment of the present disclosure; Fig. 8 is a schematic diagram of a dust cover according to an embodiment of the present disclosure. Referring to Figs. 1 and 2, Figs. 7 and 8, in one embodiment, the bottle cap further comprises a dust cover 300, which is coupled to the outer cap structure 200, and the dust cover 300 is threadedly connected to the outer cap structure 200. For example, the outer cap structure 200 is provided with external threads, and the dust cover 300 is provided with internal threads, and the internal threads of the dust cover 300 are threadedly connected to the external threads of the outer cap structure 200. In this way, when the bottle cap is not in use, the dust cover 300 can be used to protect the bottle cap.

[0046] Referring to Fig. 8, in one embodiment, the dust cover 300 comprises a middle column structure 310, which is connected to the top inner side of the dust cover 300 at one end, and the middle column structure 310 is used to extend into the straw 140 to close the air guide hole 141. The size of the middle column structure 310 matches the inner diameter of the straw 140, and the length of the middle column structure 310 extending into the straw 140 can close the air guide hole 141. For example, the middle column structure 310 is a hollow tubular structure.

[0047] The bottle cap according to the embodiments of the present disclosure does not need to drink water, the dust cover 300 is screwed onto the outer cap structure 200, the dust cover 300 is threadedly connected to the outer cap structure 200, and the middle column structure 310 of the dust cover 300 is inserted into the channel of the straw 140 to close the air guide hole 141, so that the air in the storage tank does not flow, thereby preventing the water in the water bottle from flowing into the storage tank through the air guide hole, and the aroma and essence of the incense stick do not penetrate into the mineral water to change the taste. When water is needed, the dust cover 300 is unscrewed from the threads of the outer cap structure 200, the mineral water is tilted to a suitable angle, the water in the water bottle flows into the channel of the straw 140, the person sucks the convex suction nozzle 220, a negative pressure is generated in the straw 140, air enters the storage tank from the first through hole, and the aroma of the incense stick enters the water being drunk from the second gap, thereby achieving the purposes of aroma enhancement and sugar-free intake for bottled mineral water products.

[0048] The straw cooperates with the middle column structure 310 of the dust cover, which can close the air guide hole 141 of the straw 140 to prevent leakage, while the flip-type aroma water bottle of the related art cannot solve this technical problem.

[0049] In an embodiment, the first protruding part 320 is arranged on the side of the connection end of the center column structure 310 of the dust cover 300. For example, the first protruding part 320 is evenly distributed around the outer wall of the center column structure 310. For example, the number of the first protruding part 320 is six, and the first protruding part 320 is arranged at an interval of 60° relative to the outer wall of the center column structure 310. One end of the first protruding part 320 is connected to the inner side of the top wall of the dust cover 300, one end of the first protruding part 320 is connected to the outer wall of the center column structure 310, and the side of the first protruding part 320 away from the center column structure 310 is arranged obliquely.

[0050] For example, the first protruding part 320 is a prismatic edge, and the number and specific shape of the prismatic edge are not limited herein and can be set according to actual use requirements. Since the outer cover structure and the middle cover structure are connected by buckling, the outer cover structure and the middle cover structure are not firmly clamped, and the dust cover is screwed to make the outer cover structure be subjected to an upward force and be separated. The first protruding part 320 of the embodiment can support the straw of the middle cover structure 100, so that the outer cover structure is prevented from not supporting the dust cover 300, and the dust cover 300 is prevented from driving the inner outer cover structure 200 out when being screwed.

[0051] Referring to FIGS. 1-6, in an embodiment, the outer cover structure 200 is connected to the annular protrusion 120 by buckling. The outer cover structure 200 of the embodiment is connected to the annular protrusion 120 by buckling, so that the installation and disassembly of the outer cover structure 200 are facilitated.

[0052] For example, the outer side of the annular protrusion 120 is provided with a convex strip structure 121, the inner side of the outer cover structure 200 is provided with a groove structure 230 matched with the convex strip structure 121, and the groove structure 230 is clamped into the convex strip structure 121 to form a connection and fixation.

[0053] For example, the outer side of the annular protrusion 120 is provided with a groove structure, the inner side of the outer cover structure 200 is provided with a convex strip structure matched with the groove structure, and the groove structure is clamped into the convex strip structure to form a connection and fixation.

[0054] For example, the outer wall of the annular protrusion 120 is circumferentially provided with a first convex strip structure, and the outer wall of the annular protrusion 120 is further provided with at least one first groove structure extending in the radial direction (vertical direction), and the first groove structure separates the first convex strip structure. The inner wall of the outer cover structure 200 is circumferentially provided with a second groove structure, and the inner wall of the outer cover structure 200 is further provided with at least one second convex strip structure extending in the radial direction (vertical direction), and the second convex strip structure separates the second groove structure. The first convex strip structure and the second groove structure thereby fix the upper and lower directions of the middle cover structure and the outer cover structure, and the second convex strip structure and the first groove structure cooperate to prevent the outer cover structure from rotating.

[0055] The outer cover structure 200 of the embodiment of the present disclosure is connected and fixed with the annular protrusion 120 through the groove structure clamped into the spit structure. After the outer cover structure 200 cooperates and fixes with the annular protrusion 120, the position of the air guide hole 141 and the first through hole 210 can be positioned conveniently.

[0056] In an embodiment of the present disclosure, the included angle of the first through hole 210 and the air guide hole 141 relative to the central axis of the straw 140 is greater than a preset target angle.

[0057] Exemplarily, the included angle of the first through hole 210 and the air guide hole 141 relative to the central axis of the straw 140 is greater than 90°.
