Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fragrance equipment technology, specifically relating to a liquid storage bottle and a fragrance machine. Background Technology
[0002] A fragrance diffuser is an electronic device that emits fragrances. It uses specific technologies to release aroma molecules from fragrances into the air, thereby improving air quality and creating a comfortable and relaxing environment.
[0003] Some fragrance diffusers use heating to cause fragrance molecules to evaporate. The heating element is usually located at the bottom of the diffuser and heats the fragrance ingredients through heating elements. Under the action of heating, the fragrance molecules in the fragrance ingredients become more active, gradually changing from a liquid state to a gaseous state, and then are dispersed into the air through the ventilation system inside the machine.
[0004] Another common type of fragrance diffuser uses ultrasonic vibration to release fragrance molecules. This type of diffuser contains an ultrasonic transducer that generates tiny water vapor particles through high-frequency vibration, in which fragrance molecules dissolve. Through the ultrasonic vibration, the particles collide continuously, releasing the fragrance molecules from the fragrance into the air, where they then diffuse outwards.
[0005] The wick is a crucial component inside a fragrance diffuser, responsible for guiding liquid fragrance from the reservoir to the atomizing or heating area. When the diffuser is operating, the wick draws the fragrance from the reservoir using capillary action or other physical mechanisms and directs it to the atomizing or heating area. In atomizing fragrance diffusers, ultrasonic vibrations cause the fragrance on the wick to form tiny water droplets, which are then released into the air.
[0006] During the operation of a fragrance diffuser, liquid fragrance is drawn from the fragrance bottle along the liquid guide rod into the atomizing zone. This creates a certain negative pressure inside the fragrance bottle, which hinders the liquid fragrance from being drawn out into the atomizing zone. To ensure a continuous and stable output of liquid fragrance to the atomizing zone, the fragrance bottle needs to be equipped with a vent to maintain pressure balance between the bottle and the outside environment. However, the vent also causes liquid fragrance to leak out when the bottle is tilted. Utility Model Content

[0026] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings.
[0027] 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.
[0028] 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.
[0029] Please refer to Figures 1 to 7 This utility model provides a liquid storage bottle 20, which includes a bottle body, a bottle stopper 30, and a liquid guiding core 50. The bottle stopper 30 is inserted into the bottle opening 21 of the bottle body, and the bottle stopper 30 is provided with an installation through hole 34. The liquid guiding core 50 is inserted into the installation through hole 34, with one end extending out of the bottle body and the other end extending into the bottle body. The bottle stopper 30 is characterized by comprising a front stopper body 32 and a rear stopper body 31 spaced apart, both of which are sealed to the bottle opening 21 of the bottle body. The rear stopper 31 is located inside the bottle of the front stopper 32. A buffer cavity 22 is formed between the front stopper 32, the rear stopper 31 and the inner wall of the bottle mouth 21. A first air hole 35 is provided on the front stopper 32 and a second air hole 36 is provided on the rear stopper 31. The first air hole 35 connects the buffer cavity 22 with the external space of the bottle, and the second air hole 36 connects the buffer cavity 22 with the internal space of the bottle. The diameter of the first air hole 35 and the second air hole 36 is smaller than the diameter of the mounting through hole 34.
[0030] Please refer to Figures 1 to 7 In this invention, the second vent 36 and the first vent 35 are generally composed of fine pores. Due to the high viscosity of liquid fragrance, it is difficult for it to leak out through the fine pores, but gas can enter. The buffer chamber 22 is designed to store liquid fragrance that leaks out from the first vent 35 and to create a pressure relief effect. The buffer chamber 22, together with the second vent 36 and the first vent 35, makes it difficult for liquid fragrance to leak out when the storage bottle 20 is tilted or inverted. This invention ensures that the fragrance diffuser 10 can continuously and stably output liquid fragrance to the atomizing area during operation, while preventing liquid fragrance from leaking out from the return vent when the fragrance bottle is tilted.
[0031] Please refer to Figure 3 , Figure 6 and Figure 7 Preferably, the rear stopper body 31 includes a rear stopper portion 39 and a reinforcing rib 33. The rear stopper portion 39 is sealed to the bottle mouth 21 of the bottle body. One end of the reinforcing rib 33 is connected to the rear stopper portion 39, and the other end extends axially along the stopper 30, i.e., along the vertical direction in the figure. The buffer cavity 22 is located at the end of the rear stopper portion 39 away from the reinforcing rib 33, and the second vent 36 penetrates through the rear stopper portion 39. The rear stopper portion 39 and the reinforcing rib 33 cooperate to facilitate the installation of the stopper 30 into the bottle mouth 21, provide structural strength for the rear stopper body 31, and facilitate molding.
[0032] Please refer to Figure 3 , Figure 6 and Figure 7 Preferably, the reinforcing rib 33 gradually thins from the end connected to the rear stopper 39 towards the other end. That is, the thickness of the reinforcing rib 33 refers to its distance from the axis of the stopper 30, and it gradually thins from top to bottom. This arrangement facilitates the installation of the stopper 30 into the bottle neck 21.
[0033] Please refer to Figure 4 , Figure 6 and Figure 7 Preferably, the bottle stopper is provided with an oil return hole 37, which is located between the front stopper body 32 and the rear stopper body 31 and connects to the mounting through hole 34 and the buffer chamber 22. When the liquid guiding core rod 50 is assembled into the mounting through hole 34, the oil return hole 37 connects the buffer chamber 22 and the liquid guiding core rod 50, that is, the liquid fragrance can form a liquid return channel between the oil return hole 37, the buffer chamber 22 and the liquid guiding core rod 50. When the bottle is tilted or inverted and then straightened, the liquid fragrance that has leaked into the buffer chamber 22 can flow back along the liquid guiding core rod 50.
[0034] Please refer to Figures 2 to 7 Preferably, the front plug body 32 is provided with a downwardly recessed oil return groove 38, and the mounting through hole 34 penetrates the oil return groove 38. The oil return groove 38 is used to receive the liquid flavoring returned by the atomizer 40 to save on the flavoring. The upper end of the first air hole 35 penetrates the oil return groove 38 to facilitate air passage through the liquid storage bottle 20.
[0035] Please refer to Figures 2 to 7 Preferably, the front plug body 32 is provided with a protrusion 38a, which is located within the oil return groove 38 and extends radially inward along the oil return groove 38. The first vent 35 is located within the protrusion 38a. The protrusion 38a protrudes upward in the height direction relative to the intermediate oil return groove 38, so that the first vent 35 also protrudes upward in the height direction relative to the intermediate oil return groove 38, thus preventing the essential oil in the oil return groove 38 from clogging the first vent 35.
[0036] Please refer to Figures 4 to 7 Preferably, the first vent 35 and the second vent 36 are staggered. This staggered arrangement facilitates ventilation while further improving oil leakage prevention performance. The diameters of the first vent 35 and the second vent 36 are less than 1 mm. The second vent 36 and the first vent 35 are generally composed of fine pores. Due to the high viscosity of liquid fragrances, it is difficult for them to leak out through the fine pores, but gas can enter.
[0037] Please refer to Figures 4 to 7Preferably, when the cross-sectional area of each vent is the same, the number of first vents 35 is less than the number of second vents 36, or the overall cross-sectional area of the first vents is smaller than that of the second vents, to form a structure that facilitates ventilation and prevents oil leakage. Generally, one first vent 35 and two second vents 36 are provided due to the configuration of the buffer chamber 22. This structure, where the number of first vents 35 is less than the number of second vents 36, facilitates overall ventilation and allows the liquid fragrance in the buffer chamber 22 to flow back into the storage bottle 20 through the second vents 36, while simultaneously preventing the liquid fragrance in the buffer chamber 22 from leaking out through the first vents 35.
[0038] Please refer to Figures 1 to 7 In another aspect, this utility model provides a fragrance diffuser 10, which includes an atomizer 40 and the aforementioned liquid storage bottle 20. The atomizer 40 is disposed on the bottle opening 21, and an atomizing plate 46 for atomizing liquid fragrance is provided on the atomizer 40. The upper end of the liquid guiding core rod 50 is connected to the atomizing plate 46, and an atomizing chamber 41 is provided above the atomizing plate 46. The atomizing chamber 41 communicates with the first air hole 35, and the atomizing chamber 41 extends radially outward compared to the atomizing outlet 42. The atomizing chamber 41 is larger than the atomizing outlet 42, and when the fragrance diffuser 10 is tilted, the atomizing chamber 41 can also temporarily buffer the leaked fragrance liquid.
[0039] Please refer to Figures 1 to 3 Preferably, the atomizer 40 includes an upper housing 43 and a base 44, which are detachably connected. The atomizing chamber 41 is formed by the upper housing 43 and the base 44. A sealing ring 45 is provided at the connection between the upper housing 43 and the base 44. The atomizing outlet 42 is located at the top of the upper housing 43, and the atomizing plate 46 is mounted on the base 44. The arrangement of the upper housing 43 and the base 44 facilitates the installation of the atomizer 40. Simultaneously, the sealing ring 45 ensures that the fragrance liquid leaking into the atomizing chamber 41 will not leak from the connection between the upper housing 43 and the base 44. The lower end of the base 44 is connected to the bottle mouth 21 via an internal threaded connection port 47, facilitating the installation of both.
