Description

Technical Field

[0001] This utility model belongs to the field of fragrance technology, specifically relating to a fragrance device. Background Technology

[0002] CN221132704U discloses an atomizing head and a fragrance device. The fragrance device includes an atomizing head and a liquid storage bottle screwed to the housing of the atomizing head. The atomizing core of the atomizing head is connected to a suction tube, one end of which extends into the liquid storage bottle, and a filter cap is provided at the end of the suction tube. The atomizing head includes a housing, an atomizing core disposed within the housing, and a mist outlet disposed on the housing to connect the interior and exterior spaces. One end of the atomizing core is connected to the mouth of a liquid storage bottle. The housing also includes a first atomizing chamber and a second atomizing chamber disposed on the side of the atomizing core away from the liquid storage bottle. The first atomizing chamber is connected to the atomizing core, and its sidewall is provided with multiple sieve holes to filter out large droplets atomized by the atomizing core. The second atomizing chamber is fitted around the outer periphery of the first atomizing chamber, making the first and second atomizing chambers relatively independent, thereby blocking mid-to-high frequency noise and reducing the noise of the atomizing head during use. The second atomizing chamber is connected to the mist outlet. The atomizing core atomizes the semen in the liquid storage bottle into droplets, and the atomized droplets enter the second atomizing chamber through the sieve holes of the first atomizing chamber and are sprayed out from the mist outlet. The atomizing head designed above can block large droplets from overflowing through the sieve holes of the first atomizing chamber, thereby ensuring that the droplets are sprayed out evenly. It also reduces noise, improves resource utilization, and enhances the user experience.

[0003] Analysis of existing technologies reveals that without a vent, when the fragrance device is operating, negative pressure may form inside the reservoir as the atomizing core continuously draws in fragrance liquid. This negative pressure hinders the flow of fragrance liquid from the suction tube to the atomizing core, reducing atomization efficiency. The negative pressure effect may also cause the fragrance liquid in the suction tube to become stuck, preventing it from reaching the atomizing core for atomization, further affecting the fragrance release. On the other hand, while a vent can solve the negative pressure problem and improve fragrance liquid output efficiency, it may also introduce new problems. For example, improperly designed vents (such as incorrect location, size, or shape) may cause fragrance liquid in the reservoir to overflow through the vent when the device is tilted or shaken violently, resulting in leakage.

Detailed Implementation

[0019] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings.

[0020] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0021] 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.

[0022] This utility model provides a fragrance device, which includes an atomizing head 100 and a liquid storage bottle 200. The mouth of the liquid storage bottle 200 is sealed to the atomizing head 100. The liquid storage bottle 200 is provided with a liquid storage cavity 203 communicating with the mouth of the bottle. The liquid storage cavity 203 is used to contain liquid fragrance. A suction tube 201 and a return air tube 300 are inserted into the liquid storage cavity 203. The ends of the suction tube 201 and the return air tube 300 near the mouth of the bottle are both installed on the atomizing head 100. The suction tube 201 is used to transport the liquid fragrance in the liquid storage cavity 203 to the atomizing head 100. The atomizing head 100 atomizes the liquid fragrance. The return air tube 300 connects the liquid storage cavity 203 with the external space of the liquid storage bottle 200. The return air tube 300 is used to transport the gas in the external space of the liquid storage bottle 200 into the liquid storage cavity 203.

[0023] The return air tube 300 can solve the negative pressure problem during operation and ensure the release effect of the fragrance. On the other hand, the other end of the return air tube 300 extends from the bottle opening of the liquid storage bottle 200 into the liquid storage chamber 203. When the fragrance device is tilted or shaken violently, it is difficult for the liquid fragrance to flow out of the liquid storage bottle 200 and the atomizing head 100 from the return air tube 300.

[0024] When the atomizing core 102 is working, a suction force is generated in the liquid channel of the suction tube 201, forming a negative pressure area. This negative pressure area extends along the suction tube 201 into the liquid storage chamber 203, affecting the air pressure distribution within the liquid storage chamber 203. That is, during spraying, the air pressure in the liquid storage chamber 203 decreases, resulting in negative pressure. This manifests as the air pump requiring more power to draw the same amount of liquid fragrance, or drawing less liquid fragrance with the same power. To balance this air pressure situation within the bottle 2, in some embodiments, a return oil pipe can be used to partially alleviate the problem of difficulty in drawing liquid fragrance due to the reduced air pressure in the liquid storage chamber 203. One end of the return oil pipe is connected to the atmosphere, and the other end is immersed in the liquid fragrance. When negative pressure is generated in the liquid storage chamber 203, the liquid fragrance in the return oil pipe is partially squeezed into the liquid storage chamber 203 under the action of the air pressure difference, ensuring that the air pressure in the liquid storage chamber 203 does not decrease significantly. Furthermore, this utility model can directly transport air from the outer space of the liquid storage bottle 200 to the liquid storage chamber 203 through the return air pipe 300. The air pressure in the liquid storage chamber 203 is basically consistent with the atmospheric pressure, and no additional power is consumed by the air pump.

[0025] In a preferred embodiment, the liquid suction end of the suction tube 201 and the gas output end of the return gas tube 300 are located at the bottom of the liquid storage chamber 203, and the bottom ends of both the suction tube 201 and the return gas tube 300 are fixedly connected by a connecting branch tube 301. The location of the liquid suction end and the gas output end at the bottom of the liquid storage chamber 203 allows the suction tube 201 to draw the vast majority of the liquid fragrance onto the atomizing head 100, while also preventing leakage of liquid fragrance from the atomizing head 100 when the liquid storage bottle 200 is tilted. The connecting branch tube 301 ensures that the positions of the suction tube 201 and the return gas tube 300 are relatively fixed, further improving the effect of preventing liquid fragrance leakage from the atomizing head 100. The reason why the two tubes, the suction tube 201 and the air return tube 300, are connected together is to prevent one tube from being in the liquid fragrance and the other from being in the air when the fragrance device is tilted on its side, thus preventing oil leakage. When the two tubes are connected together, the fragrance device will be either completely submerged in oil or completely in the air when it is tilted on its side, so there will be no oil leakage.

[0026] In a preferred embodiment, the liquid suction end of the suction tube 201 and the gas output end of the return gas tube 300 are connected to the same connecting branch tube 301, and both are connected to the liquid storage chamber 203 through the connecting branch tube 301. This facilitates both gas return and liquid suction, and also makes it easier to form the connecting branch tube 301, the suction tube 201, and the return gas tube 300.

[0027] In a preferred embodiment, the connecting branch pipe 301 is further provided with a first cavity 302 and a second cavity 303. The suction pipe 201 is inserted and installed on the first cavity 302 and communicates with the liquid storage cavity 203 through the first cavity 302. The return air pipe 300 is inserted and installed on the second cavity 303 and communicates with the liquid storage cavity 203 through the second cavity 303.

[0028] By providing a first cavity 302 and a second cavity 303 on the connecting branch pipe 301, air return and liquid suction are achieved through the two cavities. At the same time, the liquid suction pipe 201 and the air return pipe 300 are installed by plugging and unplugging, which facilitates installation and the forming of the connecting branch pipe 301.

[0029] In a preferred embodiment, the bottom of the connecting branch pipe 301 is provided with an opening, the lower ends of the first cavity 302 and the second cavity 303 are connected together, and the connection between the two is also connected to the opening. The suction pipe 201 and the return pipe 300 are respectively connected through the open liquid storage cavity 203.

[0030] The bottom of the connecting branch pipe 301 is provided with an opening, so that the liquid absorption and gas return are located at a lower position inside the bottle bottom, which can ensure that the liquid fragrance in the liquid storage bottle 200 is completely absorbed, and at the same time ensure that the liquid fragrance does not leak from the opening to the atomizing head 100 when it is poured.

[0031] In a preferred embodiment, the connecting branch pipe 301 is also provided with a notch 304 at the opening. The notch 304 extends in a vertical direction and its lower end is connected to the opening. The notch 304 is connected to the first cavity 302 and the second cavity 303. The bottom inner wall of the liquid storage cavity 203 forms an upwardly convex arc surface 202. The opening is provided corresponding to the arc surface 202, and the height of the opening from the arc surface 202 is not higher than 1 cm.

[0032] Outside air can enter the liquid storage chamber 203 through the notch 304 and the opening. The liquid fragrance in the liquid storage chamber 203 enters the suction pipe 201 through the notch 304 and the opening. The raised arc surface 202, in conjunction with the notch 304 and the opening, ensures that most of the liquid fragrance in the liquid storage chamber 203 is sucked out, without affecting the air return and liquid suction effect.

[0033] In a preferred embodiment, the atomizing head 100 is provided with an atomizing core 102, the atomizing core 102 is provided with a liquid delivery channel 105 and a gas delivery channel 103, the output end of the suction tube 201 is pluggable and detachable to the input end of the liquid delivery channel 105, the input end of the gas delivery channel 103 is also connected to an air inlet 104, the output end of the gas delivery channel 103 cooperates with the output end of the liquid delivery channel 105 to atomize the liquid fragrance, the atomizing core 102 is provided with a return air hole 106, and the input end of the return air tube 300 is pluggable and detachable to the return air hole 106.

[0034] The air inlet 104 can be connected to high-pressure gas and delivered to the output end of the air delivery channel 103, creating a pressure difference between the output end of the liquid delivery channel 105 of the atomizing core 102 and the liquid storage chamber 203. This drives the liquid fragrance in the liquid storage chamber 203 to be delivered to the output end of the liquid delivery channel 105 through the suction tube 201 for liquefaction. How the atomizing core 102, in conjunction with the liquid delivery channel 105 and the air delivery channel 103, draws out and atomizes the liquid fragrance using high-pressure gas is existing technology and will not be elaborated here. The return air tube 300 is pluggable and detachable from the return air port 106, and the output end of the suction tube 201 is pluggable and detachable from the input end of the liquid delivery channel 105, facilitating installation and the formation of the return air tube 300, suction tube 201, and atomizing core 102.

[0035] In a preferred embodiment, the atomizing head 100 is provided with an atomizing chamber 101 above the atomizing core 102. The output end of the gas delivery channel 103 and the output end of the liquid delivery channel 105 are located inside the atomizing chamber 101. The return air hole 106 is connected to the atomizing chamber 101 and is located at the bottom of the atomizing chamber 101. The return air hole 106 is also used to return the liquid fragrance located in the atomizing chamber 101.

[0036] This configuration allows the return pipe 300 to function as a return pipe for both gas and liquid fragrance.

[0037] During use, the air inlet 104 uses high-pressure gas to continuously draw the liquid fragrance in the liquid storage chamber 203 into the atomizing core 102 for atomization. At the same time, as the liquid fragrance in the liquid storage chamber 203 is continuously consumed, the liquid level drops, causing the air pressure on the liquid surface to decrease. At this time, since the return air pipe 300 is connected to the outside, and a pressure difference is formed between the liquid in the liquid storage chamber 203 and the outside, outside air flows into the liquid storage chamber 203 through the return air pipe 300, ensuring air pressure balance and thus ensuring the efficiency of the liquid fragrance output from the liquid storage chamber 203 through the suction pipe 201.

[0038] When the fragrance device is tilted, since the liquid suction tube 201 and the air return tube 300 are located inside the liquid storage chamber 203, most of the liquid fragrance can be prevented from leaking into the atomizing head 100. Generally speaking, the closer the liquid suction port of the liquid suction tube 201 and the air return port of the air return tube 300 are to the bottom of the liquid storage chamber 203, the better the effect of preventing liquid fragrance from leaking into the atomizing head 100.
