Description

Technical Field

[0001] This utility model belongs to the field of fragrance technology, specifically relating to a liquid storage bottle and a fragrance diffuser. Background Technology

[0002] Chinese patent CN217793904U discloses a diffuser whose structure includes a main body, an atomizing head, an air pump, and other key components. The main body has a spray nozzle surrounded by multiple air jets connected to the internal airflow path. The atomizing head integrates an atomizing base, an atomizing core, and an atomizing cap. The atomizing core connects to the gas and liquid flow channels, which are respectively connected to the air pump and the liquid storage bottle. The spray nozzle is located on the atomizing cap, and the atomizing base is covered by a cover, forming multiple independent chambers: an atomizing chamber, a first chamber, and a second chamber. A fan connects the first and second chambers to promote airflow circulation. The side wall of the atomizing base has ventilation openings, and the cover has through holes that connect to the spray nozzle. The air jets communicate with the second chamber, achieving a long-distance spray effect.

[0003] Currently, the design of the atomizing head in aroma diffusers presents significant user operational risks and performance hazards. While the atomizing head is conveniently attached to the mouth of the essential oil bottle for easy installation and removal, this also creates potential problems, as users often struggle to assess the quality of the essential oils they purchase. These oils may contain impurities or have inconsistent viscosity. Prolonged use of such oils can not only affect the atomization effect of the atomizing head but may also clog the atomizing coil, ultimately impacting the overall performance and lifespan of the aroma diffuser.

[0004] Furthermore, this direct connection between the atomizer head and the essential oil bottle leaves the bottle completely open after the atomizer head is removed, increasing the risk of contamination, especially in dusty or humid environments. Contamination not only affects the diffusion effect but may also pose a threat to the user's health. Utility Model Content

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] Please refer to Figures 1 to 9 This utility model provides a liquid storage bottle, which includes a bottle body 100 and a stopper 109. The bottle body 100 is provided with a bottle mouth 101 and a liquid storage cavity 102, which communicates with the bottle mouth 101 and is used to store liquid fragrance. The stopper 109 is inserted into the bottle mouth 101 and seals with it. The stopper 109 is characterized by having an atomizing core 104, a 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 liquid delivery channel 107 has an outlet 105, and the gas delivery channel 108 has an outlet 105. The air outlet 106 is located above the liquid surface. The input end of the connector 113 is used to connect to the air supply device. The output end of the connector 113 is connected to the air supply channel 108. The connector 113 provides airflow to the atomizing core 104. One end of the suction tube 116 is inserted into the liquid storage chamber 102, and the other end is connected to the liquid supply channel 107. The 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 suction tube 116. The bottle stopper 109 is also provided with a mist outlet channel 112.

[0037] 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.

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.

[0038] Please refer to Figures 1 to 9In a preferred embodiment, the stopper 109 is detachably inserted and removed from the bottle neck 101 and seals with it. Alternatively, the stopper 109 and the bottle neck 101 are respectively provided with an anti-disassembly component a09 and an anti-disassembly part a01, which cooperate with each other after the stopper 109 is inserted into the bottle neck 101. This utility model also provides two installation methods for the stopper 109: a detachable insertion / removal type and an anti-disassembly type, which enhances the flexibility and safety of the liquid storage bottle. Detachable insertion / removal type: The stopper 109 is inserted and removed from the bottle neck 101, which is convenient for replacement and maintenance. The stopper 109 and the bottle neck 101 are respectively provided with an anti-disassembly component a09 and an anti-disassembly part a01, which cooperate with each other to prevent the stopper 109 from being removed. If forcibly removed, the seal between the stopper 109 and the bottle neck 101 will be damaged, rendering the liquid storage bottle unusable.

The lower stopper body 111 is inserted into the bottle mouth 101, and the lower stopper body 111 and the bottle mouth 101 are sealed together by a sealing ring 114. An external thread is provided on the outer peripheral wall of the bottle mouth 101, and the bottle mouth 101 is fixed to the atomizing head 200 by the external thread. Alternatively, the bottle stopper 109 includes an inner stopper body d09 and an external threaded sleeve b09. The external threaded sleeve b09 is fitted onto the outer peripheral wall of the bottle mouth 101, and an external thread is provided on the outer side of the external threaded sleeve b09. The external threaded sleeve b09 is fixed to the atomizing head 200 by the external thread. The inner stopper body d09 is inserted into the bottle mouth 101, and the upper ends of the inner stopper body d09 and the external threaded sleeve b09 are connected. The upper ends of both are sealed to the top of the bottle mouth 101 by a sealing ring 114. This utility model also provides two corresponding solutions for sealing the bottle stopper 109 to the bottle mouth 101, enhancing the sealing and stability of the liquid storage bottle. In the first solution, the lower stopper 111 is sealed to the bottle mouth 101 by a sealing ring 114, and the bottle mouth 101 is fixed to the atomizing head 200 by an external thread. In the second solution, the inner stopper d09 and the external threaded sleeve b09 are combined. The inner stopper d09 is inserted into the bottle mouth 101, and the external threaded sleeve b09 is fixed to the atomizing head 200 by an external thread and sealed to the top of the bottle mouth 101 by a sealing ring 114. When changing the fragrance, the second solution, compared to the first solution, encourages users to develop the habit of using the new matching fragrance, atomizing core 104, bottle stopper 109, and bottle body 100 together.

[0040] Please refer to Figures 7 to 9In a preferred embodiment, the bottle stopper 109 includes an inner stopper body d09 and an external threaded sleeve b09. The external threaded sleeve b09 is fitted onto the outer peripheral wall of the bottle mouth 101. An anti-removal component a09 is provided on the inner peripheral wall of the external threaded sleeve b09, and an anti-removal part a01 is provided on the outer peripheral wall of the bottle mouth 101. The anti-removal part a01 corresponds to the anti-removal component a09. The external threaded sleeve b09 and the bottle mouth 101 are fixed by an interference fit between the anti-removal component a09 and the anti-removal part a01. The interference fit between the anti-removal component a09 and the anti-removal part a01 further enhances the connection stability between the bottle stopper 109 and the bottle mouth 101. Furthermore, the anti-removal component a09 has a certain degree of elasticity to better achieve the interference fit.

[0041] Please refer to Figures 7 to 9 In a preferred embodiment, a limiting member c09 and a limiting groove b01 are respectively provided on the inner peripheral wall of the external threaded sleeve b09 and the outer peripheral wall of the bottle mouth 101. Both the limiting member c09 and the limiting groove b01 extend axially along the bottle mouth 101. When the bottle stopper 109 is inserted into the bottle mouth 101, the limiting member c09 is inserted into the limiting groove b01 along the axial direction of the bottle mouth 101. The limiting member c09 and the limiting groove b01 limit the rotation of the bottle stopper 109 relative to the bottle mouth 101. The limiting member c09 and the limiting groove b01 extend axially along the bottle mouth 101, and when the bottle stopper 109 is inserted into the bottle mouth 101, the limiting member c09 is inserted into the limiting groove b01, thus achieving the limiting function. The above-mentioned cooperation restricts the rotation of the stopper 109 relative to the bottle mouth 101. When the atomizing head 200 is connected to the external threaded sleeve b09 through the connecting thread 204, the external threaded sleeve b09 will not rotate with the atomizing head 200, thus improving the efficiency and accuracy of assembly.

[0042] Please refer to Figures 7 to 9 In a preferred embodiment, both the anti-tampering component a09 and the anti-tampering part a01 are annular protrusions. They extend radially inward and outward along the bottle opening 101, respectively, and their total radial length is greater than the distance between the inner circumferential wall of the external threaded sleeve b09 and the outer circumferential wall of the bottle opening 101. When the bottle stopper 109 is inserted into the bottle opening 101, the anti-tampering component a09 is located below the anti-tampering part a01, and the limiting groove b01 penetrates the anti-tampering part a01 axially along the bottle opening 101. The widths of the limiting component c09 and the limiting groove b01 are compatible. The radial direction of the bottle opening 101 generally refers to the radius direction of the bottle opening 101. The annular protrusions serving as the anti-tampering component a09 and the anti-tampering part a01, along with the limiting groove b01, effectively achieve an interference fit, further enhancing the connection stability and limiting effect between the bottle stopper 109 and the bottle opening 101, while also facilitating the molding of the bottle body 100 and the bottle stopper 109.

[0043] Please refer to Figures 1 to 9In 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 gas input end 119 of the atomizing core 104 is pluggably mounted to the output end of the mounting through-hole. 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.

[0044] In a preferred embodiment, the connector 113 is connected to the stopper body via multiple connecting ribs. 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. The misting channel 112 passes through the multiple connecting ribs 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. By setting the connecting ribs, the structural strength of the stopper 109 is enhanced, and the path of the misting channel 112 is optimized, improving the atomization effect. On the other hand, the misting channel 112, connector 113, connecting ribs, and stopper body are easier to integrally mold.
