Technical Field

[0001] The utility model belongs to the technical field of atomization, and in particular relates to a liquid storage container, an atomizer and an electronic atomization device. Background Art

[0002] An electronic atomization device is a device used to atomize a liquid medium into an aerosol. It mainly includes a liquid storage container for storing atomized liquid and an atomization assembly assembled on the liquid storage container. The color of the liquid storage container is usually transparent or brown and translucent, which is beneficial for the user to observe the remaining oil in the liquid storage container, thereby eliminating the user's anxiety about use and enhancing the user's experience with the electronic atomization device.

[0003] Some flavor components are added to the atomizer liquid to enhance the user's smoking experience. As the electronic atomizer device is placed or used for a long time, the fragrance of the atomizer liquid will become weaker and weaker, commonly known as taste attenuation. The reduction of the flavor components of the remaining atomizer liquid in the storage container is one of the reasons for taste attenuation. The atomizer liquid and some flavor components in the atomizer liquid are decomposed or mutated in the liquid storage container when exposed to light, resulting in an increasing difference between the existing flavor ratio in the remaining atomizer liquid and the original flavor ratio, causing taste attenuation.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] Example:

[0033] like Figure 2~3 As shown, the first aspect of this embodiment provides a liquid storage container 100, wherein the liquid storage container 100 is provided with a liquid storage space 400, an opening communicating with the liquid storage space 400, and a vent pipe 140 extending from the surface of the liquid storage container 100 into the liquid storage space 400, wherein the opening is used for connecting and cooperating with the atomization assembly 200;

[0034] At least a portion of the liquid storage container 100 includes a material that can change color after being excited by energy. The material that can change color after being excited by energy is used to adjust the light transmittance of the liquid storage container 100 according to environmental changes.

[0035] In this embodiment, when the light transmittance of the liquid storage container 100 adjusted according to environmental changes is high, the user can observe the remaining amount of atomized liquid in the liquid storage container 100. When the light transmittance of the liquid storage container 100 adjusted according to environmental changes is low, the speed at which the flavor components in the atomized liquid are decomposed or mutated by light is slowed down, which is beneficial to the storage of the atomized liquid in the liquid storage container 100.

[0036] Furthermore, the light transmittance of the liquid storage container 100 is negatively correlated with the change in ambient light intensity.

[0037] When the ambient light intensity decreases, the light transmittance of the liquid storage container 100 increases, and the user can observe the remaining amount of atomized liquid in the liquid storage space 400. When the ambient light intensity increases, the color of the liquid storage container 100 becomes darker under the irradiation of light, and the light transmittance of the liquid storage container 100 decreases, which slows down the speed of the flavor components in the atomized liquid being decomposed or mutated by light, and is beneficial to the storage of the atomized liquid in the liquid storage container 100.

[0038] Furthermore, the light transmittance of the liquid storage container 100 ranges from 20% to 80%.

[0039] As the ambient light intensity increases, the light transmittance of the liquid storage container 100 gradually decreases from a maximum of 80% to 20%, so that the light intensity entering the liquid storage container 100 is maintained at least below 500 Lux.

[0040] Furthermore, the material that can change color after being excited by energy adjusts the transmittance of at least part of the ultraviolet light and at least part of the visible light passing through the liquid storage container 100.

[0041] As an example, a material that changes color after being excited by energy can adjust the transmittance of the liquid storage container 100 to at least part of the light with a wavelength below 760 nm as the intensity of ambient light changes.

[0042] Among them, the material that can change color after being excited by energy can adjust the transmittance of the liquid storage container 100 to different wavelengths of light to be the same or different as the ambient light intensity changes. The material that can change color after being excited by energy can make the transmittance of the liquid storage container 100 to light of a specific wavelength lower. For example, it can be adjusted to make the transmittance of the liquid storage container 100 to ultraviolet rays with a wavelength below 400nm much lower than the transmittance of light of other wavelengths as the temperature changes, effectively blocking ultraviolet rays that have a great influence on the deterioration and decomposition of the atomized liquid and the essence in the atomized liquid. At the same time, visible light has little effect on the deterioration and decomposition of the atomized liquid and the essence in the atomized liquid, so that the liquid storage container 100 can maintain a large transmittance for visible light of 380nm~760nm.

[0043] The above is only an example, and technicians can confirm the transmittance of the required liquid storage container 100 to light of different wavelengths according to the different product characteristics of the atomizer 10 to adjust the actual composition and properties of the material that can change color after being excited by energy.

[0044] Furthermore, at least a portion of the wall material of the liquid storage container 100 is a light-transmitting wall material 110 , and the light-transmitting wall material 110 contains a material that can change color after being excited by energy.

[0045] Preferably, the light-transmitting wall material 110 is made of thermoplastic plastics such as resin. In other embodiments, inorganic materials with high light transmittance such as glass can also be used as the light-transmitting wall material 110 .

[0046] The light-transmitting wall material 110 and the material that can change color after being excited by energy should have stable physical and chemical properties after being combined. For example, if thermoplastic plastics such as resin are used as the main components of the light-transmitting wall material 110, it is preferred to use organic materials that can change color after being excited by energy. During preparation, the light-transmitting wall material 110 is obtained by dissolving the material that can change color after being excited by energy in the thermoplastic plastic and polymerizing it.

[0047] Furthermore, at least part of the wall material of the liquid storage container 100 is a light-transmitting wall material 110 , and at least one side of the light-transmitting wall material 110 is provided with a color-changing layer 120 made of a material that can change color after being excited by energy.

[0048] like Figure 2 As shown, the wall material of the liquid storage container 100 is a light-transmitting wall material 110 as a whole, and a color-changing layer 120 made of a photochromic material is provided on the inner side of the light-transmitting wall material 110 .

[0049] As an example, the color-changing layer 120 can be arranged on the inner side and / or outer side of the light-transmitting wall material 110, or can alternately cover different areas on both sides of the light-transmitting wall material 110, as long as the color-changing layer 120 can cover all areas of the light-transmitting wall material 110 that allow light to pass through.

[0050] Taking the example of using thermoplastic plastics such as resin as the main component of the light-transmitting wall material 110 and the material that can change color after being excited by energy as an organic material, the infiltration method can be used to directly infiltrate the material that can change color after being excited by energy into the light-transmitting wall material 110 to form a color-changing layer 120 on the surface of the light-transmitting wall material 110. The color-changing layer 120 can also be formed on the surface of the light-transmitting wall material 110 by a coating method such as spraying.

[0051] Preferably, the surface of the color-changing layer 120 may also be covered with a protective layer, and the protective layer is used to protect the color-changing layer 120 . The protective layer may be formed on the surface of the color-changing layer 120 by coating or the like.

[0052] Furthermore, the light-transmissive wall material 110 is at least partially disposed in a region of the liquid storage container 100 corresponding to the liquid storage space 400 .

[0053] As an example, Figure 2 As shown, the wall material of the liquid storage container 100 is a light-transmitting wall material 110. It should be known that the opening of the liquid storage container 100 can be light-transmitting or opaque, and the wall material of the liquid storage container 100 can also be partially light-transmitting, as long as the user can observe the remaining amount of the atomized liquid in the liquid storage space 400 through the liquid storage container 100.

[0054] Furthermore, the material that can change color after being excited by energy is a photochromic material, a thermochromic material or an electrochromic material.

[0055] Photochromic material refers to a material that can undergo photochromic changes. Photochromism refers to the chemical reactions that occur when certain compound materials are exposed to light of a certain wavelength and intensity, which causes changes in the compound structure and the color of the compound. After the light is removed or exposed to light of another wavelength and intensity, the color is restored or a new change occurs.

[0056] As an example, Figure 2 As shown, the wall material of the liquid storage container 100 is a light-transmitting wall material 110 as a whole, and a color-changing layer 120 made of a photochromic material is provided on the inner side of the light-transmitting wall material 110 .

[0057] The photochromic compound used to prepare the color-changing layer 120 or the transparent wall material may be selected from, but not limited to, organic photochromic materials, or inorganic photochromic compounds such as silver halide and tungsten trioxide.

[0058] When the ambient light intensity decreases, the light transmittance of the liquid storage container 100 increases, and the user can observe the remaining amount of atomized liquid in the liquid storage space 400. When the ambient light intensity increases, the color of the color-changing layer 120 becomes darker under the irradiation of light, and the light transmittance of the liquid storage container 100 decreases, which slows down the speed of the flavor components in the atomized liquid being decomposed or mutated by light, and is beneficial to the storage of the atomized liquid in the oil cup.

[0059] Thermochromic materials refer to materials that change color with temperature within a certain temperature range. Thermochromic materials are preferably thermochromic organic materials, such as spiropyran, fluorescent derivatives, polythiophene, liquid crystal materials, etc. The color change temperature of thermochromic organic materials is relatively wide, usually -100~100℃.

[0060] Electrochromism is a phenomenon in which the optical properties of a material undergo a stable, reversible color change under the action of an applied electric field, which manifests itself in a reversible change in color and transparency. Materials with electrochromic properties are called electrochromic materials.

[0061] As an example, the electrochromic material used to prepare the color-changing layer 120 or the transparent wall material may be an inorganic electrochromic material or an organic electrochromic material, such as tungsten trioxide, viologens or tetrathiafulvalene.

One end of the ventilation tube 140 is trumpet-shaped, and the user inhales the aerosol-shaped atomized liquid through one end of the ventilation tube 140. At least a portion of the liquid storage container 100 includes a material that can change after being excited by energy, so as to prevent the flavor components in the atomized liquid from being decomposed or mutated in the oil cup when exposed to light, thereby providing the user with a long-term taste experience. The user can also check the remaining amount of atomized liquid in the atomizer 10 through the liquid storage container 100 with variable light transmittance, thereby alleviating the user's anxiety in use.
