[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] Please refer to Figures 1 to 7 The present invention provides a liquid storage bottle in view of the prior art. The liquid storage bottle includes a bottle body 100 and a bottle stopper 109. The bottle body 100 is provided with a bottle mouth 101 and a liquid storage cavity 102. The liquid storage cavity 102 is connected to the bottle mouth 101 and is used to store liquid fragrance. The bottle stopper 109 is inserted into the bottle mouth 101 and seals with it.

[0040] The bottle stopper 109 is provided with an atomizing core 104, a liquid suction tube 116, and a connector 113. The atomizing core 104 is provided with a liquid delivery channel 107 and a gas delivery channel 108.

The input end of the connector 113 is used to connect to an external airflow supply device, and the output end of the connector 113 is connected to the gas delivery channel 108. The connector 113 provides airflow to the atomizing core 104. One end of the liquid suction tube 116 is inserted into the liquid storage chamber 102, and the other end is connected to the liquid delivery channel 107. The liquid suction tube 116 is used to transport the liquid fragrance in the liquid storage chamber 102 to the atomizing core 104. The atomizing core 104 mixes and atomizes the airflow provided by the atomizing core 104 with the liquid fragrance provided by the liquid suction tube 116. The bottle stopper 109 is also provided with a mist outlet channel 112.

[0041] The atomizing core 104 has a liquid delivery channel 107 and an air delivery channel 108. The liquid outlet 105 of the liquid delivery channel 107 and the air outlet 106 of the air delivery channel 108 are located above the liquid surface.

The suction tube 116 delivers the liquid fragrance from the storage chamber 102 to the atomizing core 104, where it mixes with the airflow and is atomized. The atomized fragrance is output through the mist outlet channel 112. Through the atomizing core 104, suction tube 116, and connector 113, the liquid fragrance is atomized and output through the mist outlet channel 112, resulting in a compact and easy-to-use storage bottle. Since the atomizing core 104 has low cost and a short sales period, it is placed inside the bottle stopper 109. After use, it can be discarded along with the bottle. When replacing, a new atomizing core 104, bottle stopper 109, and bottle body 100 are used, facilitating replacement while ensuring atomization effect.

[0042] Please refer to Figures 1 to 7 In a preferred embodiment, the bottle stopper 109 is detachably inserted and removed from the bottle opening 101 and seals with it.

[0043] Please refer to Figures 1 to 7The bottle stopper 109 is provided with a sealing ring 114 and a first protruding edge 103 extending outward from the surface of the bottle stopper 109. When the surface of the first protruding edge 103 abuts against the inner wall of the bottle mouth 101 or the first protruding edge 103 abuts against the step at the connection between the bottle mouth 101 and the bottle body 100, the bottle stopper 109 is fixed to the bottle mouth 101. In a preferred embodiment, the bottle stopper 109 includes an upper stopper body 110 and a lower stopper body 111. The lower stopper body 111 is inserted into the bottle mouth 101. A first protruding edge 103 is provided on the lower surface of the lower stopper body 111. A sealing ring 114 is sleeved between the upper stopper body 111 and the lower stopper body 110. When the surface of the first protruding edge 103 abuts against the inner wall of the bottle mouth 101 and the sealing ring 114 abuts against the top of the bottle mouth 101, the lower stopper body 111 is fixed to the bottle mouth 101. In other preferred embodiments, when the first protruding edge 103 abuts against the step at the connection between the bottle mouth 101 and the bottle body 100, and the sealing ring 114 abuts against the top of the bottle mouth 101, the lower stopper body 111 is fixed to the bottle mouth 101 by the first protruding edge 103 and the sealing ring 114. By setting a first protruding edge 103 and a sealing ring 114 to form a double-layer seal, the liquid storage bottle is effectively sealed to prevent essential oil leakage and environmental pollution, and also to ensure the effectiveness of the fragrance diffuser.

[0044] The bottle mouth 101 has an external thread on its outer peripheral wall, and the bottle mouth 101 is fixed to the atomizing head 200 by the external thread. The upper ends of both are sealed to the top of the bottle mouth 101 by a sealing ring 114; that is, the lower stopper 111 and the bottle mouth 101 are sealed to each other by a sealing ring 114, and the bottle mouth 101 is fixed to the atomizing head 200 by the external thread.

[0045] Please refer to Figures 1 to 7 In a preferred embodiment, the bottle stopper 109 includes a tubular stopper body that seals against the inner wall of the bottle opening 101. The connector 113 is a connecting tube inserted into and connected to the stopper body. The connector 113 has a mounting through hole, and its input end is used for plugging and unplugging an airflow supply device. The gas input end 119 of the atomizing core 104 is pluggably mounted to the output end of the mounting through hole. The top of the atomizing core 104 has a second protruding edge 118 that passes through the connector 113 and is fixed to the bottle stopper 109. The second protruding edge 118 is truncated cone-shaped. A mist outlet channel 112 is formed between the inner wall of the stopper body and the outer wall of the connector 113. This design results in a compact and easily connected bottle stopper 109 and connector 113, facilitating installation and maintenance.

[0046] In a preferred embodiment, the gas input end 119 of the atomizing core 104 has a second protruding edge 118 at its top. The gas input end 119 is pluggably mounted to the output end of the mounting through hole via the second protruding edge 118 and fixed to the connecting pipe. By providing the second protruding edge 118, the stability of the connection can be effectively improved, preventing the atomizing core 104 from falling off the connector 113, improving the stability of gas delivery, effectively ensuring the uniformity of atomization, ensuring the reliability of the equipment, and thus improving the user experience; and connecting The connector 113 is connected to the plug body through multiple connecting ribs 210. The liquid outlet 105 of the infusion channel 107 and the air outlet 106 of the gas infusion channel 108 are both located below the connecting ribs 210. The mist outlet channel 112 passes through multiple connecting ribs 210 and coaxially surrounds the connector 113, connecting the inner cavity of the bottle body 100 and the outer space of the bottle body 100. The air outlet 106 is spaced at a preset distance from the liquid outlet 105 and their axes intersect. The air outlet 106 blows airflow from top to bottom to the outer end face of the liquid outlet 105. The connection rib 210 enhances the structural strength of the stopper 109 and optimizes the path of the mist outlet channel 112 to improve the atomization effect. Furthermore, the connector 113 can first block larger atomized particles and filter smaller atomized particles to move through the mist outlet channel 112, effectively ensuring the atomization effect. When the connector 113 is located inside the bottle, the atomized particles pass through the lower edge of the connector 113 and are then transported along the atomization channel 112, which can extend the transport path and allow the atomized particles to become smaller, further ensuring the atomization effect. On the other hand, the mist outlet channel 112, connector 113, connection rib 210, and stopper body are easier to integrally mold.

[0047] Please refer to Figure 1 and Figure 7 In a preferred embodiment, the atomizing core 104 is provided with a tube insertion sleeve 115, and a tightening part 120 is provided inside the tube insertion sleeve 115. One end of the suction tube 116 is inserted into the tube insertion sleeve 115 and communicates with the infusion channel 107. The other end of the suction tube 116 is plugged into and connected to a fragrance filter 117, and the bottom of the fragrance filter 117 is provided with multiple through holes (i.e., the bottom of the suction tube 116 is plugged into and connected to the fragrance filter 117). By providing the tightening part 120 and setting the tube insertion sleeve 115 to be narrow at the top and wide at the bottom, the insertion end of the suction tube 116 will be squeezed, which can better fix the suction tube 116, prevent the suction tube 116 from falling off, and ensure smooth infusion. The fragrance filter 117 is connected to the other end of the suction tube 116 and is used to filter impurities in the liquid fragrance. The through holes are used to transport the filtered fragrance to the suction tube 116. The installation of the tube insert sleeve 115 and the fragrance filter 117 improves the delivery efficiency of liquid fragrance and the service life of the atomizing core 104, while also facilitating the installation of the fragrance filter 117.
