DETAILED DESCRIPTION

[0030] The application will be further described in details through specific embodiments combined with the drawings.

[0031] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate way to form various embodiments.

Unless otherwise specified, "connection" and "coupling" in this application include direct and indirect connection (coupling).

[0033] The additional atomization container of the existing product atomization device is easy to leak when being filled, and cannot be flexibly supplemented. In this application, by providing a liquid outlet part in the base, when the atomization container is filled into the accommodating cavity, the base of the atomization container can be opened through the liquid outlet part to form a liquid outlet channel, thereby avoiding the defect that the existing technology needs to open the tobacco tar bottle first to cause liquid leakage. The relative sealing part is rotated to selectively communicate or cut off the liquid outlet channel, realizing flexible supplement of the liquid.

[0034] Please refer to Figure 1 In some embodiments, the present application shows the overall three-dimensional structure diagram of the liquid storage bottle.

[0035] Please refer to Figure 2 In some embodiments, the present application shows the structural explosion diagram of the liquid storage bottle.

[0036] Please refer to Figures 3-11 In some embodiments, the present application shows a liquid storage bottle, comprising: a shell 1, a base 3, and a sealed liquid outlet assembly; the shell 1 comprises an open-end accommodating space; the base 3 is arranged at the open end of the shell 1, and a fastening device is arranged between the shell 1 and the base 3 to fasten them together; the fastening device comprises a protruding part 32 and a recessed part 12 arranged separately on the base 3 and the shell 1 and fastened together; the sealed liquid outlet assembly is arranged at the open end of the shell 1 and comprises a sealing part inside the base 3 and a liquid outlet part extending out of the base 3; the sealing part and the liquid outlet part are provided with a liquid outlet channel that communicates the accommodating space with the outside of the base 3, and the liquid outlet part rotates relative to the sealing part to selectively communicate or cut off the liquid outlet channel. It can be understood that the liquid outlet channel is arranged in the liquid outlet part and the sealing part, and the liquid outlet part and the sealing part respectively form part of the liquid outlet channel. In some embodiments, the sealing part is arranged between the liquid outlet part and the liquid in the accommodating space, and the liquid outlet channel is communicated or cut off by the relative rotation of the liquid outlet part and the sealing part. Of course, in the present application, the sealing part can rotate or the liquid outlet part can rotate, or both can rotate, but the rotation amplitudes are different.

[0037] In some embodiments, the shell 1 of the liquid storage bottle can be made of various materials such as plastic and metal, forming an open-end accommodating space. This accommodating space is designed to hold liquid such as atomization liquid, and the open end of the shell 1 is sealed by the sealed liquid outlet assembly and the mounting base 3 to output the liquid in the accommodating space through the liquid outlet channel.

[0038] In some embodiments, the base 3 is stably arranged at the open end of the shell 1. The base 3 not only plays a role in closing the opening of the shell 1, but also is provided with a fastening device between the shell 1 to achieve a tight fastening between the two. Such design can ensure the sealing of the liquid storage bottle and prevent the liquid from leaking during transportation or use. The fastening device comprises a protruding part 32 and a recessed part 12 arranged separately on the base 3 and the shell 1 and fastened together. The design of these two parts makes the connection between the shell 1 and the base 3 more tight, and also enhances the overall structural strength of the liquid storage bottle.

[0039] In some embodiments, when the protruding part 32 and the recessed part 12 are fastened together, the protruding part 32 can be tightly embedded in the recessed part 12, forming a nearly seamless connection, which not only ensures the sealing of the liquid storage bottle, but also makes the entire liquid storage bottle more stable and durable.

[0040] The sealed liquid outlet assembly is arranged at the open end of the shell 1, mainly used for controlling the entry and exit of liquid. The sealed liquid outlet assembly includes a sealing part inside the base 3 and a liquid outlet part extending out of the base 3. The sealing part is responsible for maintaining the sealing of the inside of the liquid storage bottle, preventing liquid leakage in unintended circumstances. The liquid outlet part provides a controllable outlet, so that the liquid can be taken out or added as needed.

[0041] The liquid outlet channel is connected to the accommodation space to the outside of the base. The liquid outlet channel allows liquid to flow out of the accommodation space and reach the outside of the base through the liquid outlet part. The design of this channel needs to ensure that it is neither too large to cause liquid leakage, nor too small to affect the normal flow of liquid.

[0042] During use, the presence of the tight device and the sealing part ensures the sealing of the liquid storage bottle, preventing liquid leakage. The liquid storage bottle has many advantages. First, its structure is compact and stable, which can ensure safety during transportation and use. Second, the presence of the tight device and the sealing part makes the liquid storage bottle have excellent sealing performance, effectively preventing liquid leakage. In addition, the design of the liquid outlet channel makes it easy and convenient to add and take out liquid. These advantages together ensure the efficiency, safety and ease of use of the liquid storage bottle.

[0043] Please refer to Figures 1-11 In some embodiments, the protruding part 32 extends outwardly at the periphery of the base 3, and the recessed part 12 is provided on the side wall of the shell 1; or the protruding part 32 extends inwardly at the side wall of the shell 1, and the recessed part 12 is provided on the side wall of the base 3.

[0044] The connection stability between the base 3 and the shell 1 is enhanced, and at the same time, through the shape and size of the protruding part 32, the misalignment of the shell 1 and the base 3 when the liquid outlet part rotates can be effectively prevented, and the mutual positioning of the shell 1 and the base 3 is also facilitated. In addition, the protruding part 32 can also provide certain support for the shell 1, making it more stable. The recessed part 12 is provided on the side wall of the shell 1 or the recessed part 12 is provided on the side wall of the base 3, which can facilitate the embedding of the protruding part 32, and at the same time provides space for the combination of the shell 1 and the base 3, making it more convenient for users to install and disassemble the device, only need to align the protruding part 32 with the recessed part 12, and push it in to complete the installation.

[0045] Please refer to Figures 1-11In some embodiments, the fastening device is a magnetic fastening device; the protruding part 32 is a permanent magnet element or an electromagnet element, and the recessed part 12 is a paramagnetic element or is embedded with a permanent magnet or an electromagnet with opposite polarity to the protruding part 32; or the protruding part 32 is a paramagnetic element, and the recessed part 12 is embedded with a permanent magnet or an electromagnet. The magnetic fastening device is a device that uses magnetic force to achieve fastening or connection between components. The magnetic fastening device has the advantages of simple structure, easy installation, and the ability to provide stable fastening force.

[0046] In some embodiments, the protruding part 32 is designed as a permanent magnet element or an electromagnet element. The permanent magnet element has a fixed polarity and can maintain its own magnetic field state without an external magnetic field. The electromagnet element, on the other hand, needs to generate a magnetic field through an electric current, and the magnetic field strength can be adjusted by the size of the electric current. When the recessed part 12 is designed as a paramagnetic element, it can be affected by the magnetic field of the protruding part 32, but it does not have a fixed polarity itself. The paramagnetic element can be magnetized under the action of an external magnetic field, thereby interacting with the magnetic field of the protruding part 32 to achieve the fastening effect.

[0047] In some embodiments, a permanent magnet or an electromagnet can be embedded in the recessed part 12, which has opposite polarity to the protruding part 32. When the two are close to each other, due to the principle of opposite poles attracting each other, a stronger fastening effect can be achieved, providing greater fastening force and allowing long-term fastening without external power supply. When the protruding part 32 and the recessed part 12 cooperate with each other, they can be tightly combined together due to the magnetic force, not only simple in structure, but also high in fastening performance and good in durability. It can provide stable fastening effect in both static and dynamic environments.

[0048] In some embodiments, the protruding part 32 is a paramagnetic element, and the recessed part 12 is embedded with a permanent magnet or an electromagnet. The protruding part 32 is a paramagnetic element, which means that when it is subjected to a magnetic field, its magnetization direction is consistent with the direction of the external magnetic field, showing strong magnetism. The recessed part 12 is embedded with a permanent magnet or an electromagnet. A permanent magnet is a material that can maintain a certain magnetism even without an external magnetic field. An electromagnet, on the other hand, needs to generate a magnetic field through an electric current, and the magnetic field disappears after the power is turned off. The cooperation of the protruding part 32 and the recessed part 12 causes the interaction between the paramagnetic element and the permanent magnet or the electromagnet. The interaction between the two generates, enhances, and precisely controls the magnetic field. By reasonably designing the shape, size, and position of the protruding part and the recessed part, uniform distribution and precise control of the magnetic field can be achieved, thereby meeting the needs of different application scenarios.

[0049] Please refer to Figures 1-11In some embodiments, the sealed liquid outlet assembly comprises the switch element 4 and the sealing element 2; the sealing part is the sealing element 2; the liquid outlet part is the liquid outlet column 41 extending outwardly on the switch element 4, and the liquid outlet channel extends downwardly and comprises the communication hole 22 penetrating through both ends of the sealing element and the liquid outlet hole 411 penetrating through both ends of the liquid outlet column 41, and the projection of the communication hole 22 and the liquid outlet hole 411 in the liquid outlet direction is selectively coincident or staggered. It can be understood that in some embodiments, the liquid outlet channel extends downwardly, and the corresponding liquid outlet direction is downwardly, and when the projection of the communication hole 22 and the liquid outlet hole 411 in the liquid outlet direction is staggered, the liquid outlet channel is closed, and the liquid cannot flow downwardly from the upper part under the action of gravity; when the projection of the communication hole 22 and the liquid outlet hole 411 in the liquid outlet direction is coincident, the liquid outlet channel is closed, and the liquid can flow downwardly from the upper part under the action of gravity. Of course, in this embodiment, it is not required that the communication hole 22 and the liquid outlet hole 411 are completely coincident, and partial coincidence can also achieve the purpose of the present application. Further, the communication or closure of the liquid outlet channel can be controlled by the rotation of the switch element 4 of the sealed liquid outlet assembly to control the flow.

[0050] The liquid outlet column 41 not only has the function of opening and closing the liquid, but also has the function of guiding the flow direction of the liquid. The liquid outlet column 41 also has the function of a handle, and the user can push the liquid outlet column 41 to slide in the arc-shaped groove 33 to achieve the purpose of controlling the liquid switch. For example, in an implementation, the liquid outlet column 41 can be docked with an atomizer to be supplemented with liquid, and since the liquid outlet column 41 itself protrudes, it can be relatively fixed with the atomizer. When the liquid needs to be supplemented, the housing 1 is pressed and rotated, and under the premise that the housing 1 is relatively fixed with the base 3, and the base 3 is relatively fixed with the sealing element 2, the relative rotation between the sealing element 2 and the switch element 4 is realized.

[0051] The sealing element 2 can block the open end of the housing 1 to prevent liquid leakage, and it achieves the sealing effect through the close cooperation with the switch element 4 and the liquid outlet column 41, thereby preventing the liquid from flowing out in unintended circumstances. The liquid outlet part is the liquid outlet column 41 extending outwardly on the switch element 4. This design not only enhances the stability of the structure, but also provides a channel for the outflow of the liquid.

[0052] The liquid outlet hole 411 opened on the liquid outlet column 41 and the communication hole 22 opened on the sealing element 2 jointly constitute the liquid outlet channel. The communication between the communication hole 22 and the liquid outlet hole 411 ensures that the liquid can smoothly flow out of the sealed liquid outlet assembly.

[0053] When the switch element 4 is in the open state, the liquid can flow out through the liquid outlet hole 411 and the communication hole 22. When the switch element 4 is closed, the liquid cannot flow out through the close cooperation of the sealing element 2.

[0054] The sealing performance of the sealing element 2 ensures that the liquid cannot leak through the liquid outlet channel when the switching element 4 is closed, thereby not only ensuring the safety of use but also prolonging the service life of the sealed liquid outlet assembly. The sealed liquid outlet assembly realizes the control and leakage prevention functions of the liquid through the close cooperation of the switching element 4 and the sealing element 2. The reasonable design of the liquid outlet column 41 and the liquid outlet hole 411 and the communication hole 22 ensures that the liquid can flow out smoothly, controllably and stably.

[0055] Please refer to Figures 1-11 In some embodiments, the switching element 4 is rotatably arranged between the base 3 and the sealing element 2; the base 3 is provided with an arc-shaped groove 33 for the rotation of the liquid outlet column 41, and the liquid outlet column 41 extends out of the arc-shaped groove 33; the rotation of the switching element 4 switches the communication position and the cutoff position of the communication hole 22 and the liquid outlet hole 411.

[0056] The switching element 4 is a rotatably arranged element arranged between the base 3 and the sealing element 2, so that the switching element 4 can be rotated as needed to open / close the flow path of the fluid. By arranging the liquid outlet column 41 to extend out of the arc-shaped groove 33, the liquid can smoothly flow from the sealing element 2 to the liquid outlet column 41, and the flow of the liquid is further controlled to ensure the smoothness and controllability of the liquid flow.

[0057] By rotating the switching element 4, the communication position and the cutoff position between the communication hole 22 and the liquid outlet hole 411 can be switched, thereby achieving the purpose of controlling the flow of the liquid. Specifically, the communication hole 22 and the liquid outlet hole 411 can be aligned as needed to realize the flow of the liquid; or the liquid outlet hole 411 can be staggered to cut off the flow of the liquid. This operation controls the flow path of the liquid, thereby achieving precise control of the flow of the liquid.

[0058] Please refer to Figures 1-11 In some embodiments, the base 3 or the sealing element 2 is provided with a guide protrusion 31, and the sealing element 2 or the base 3 is provided with a positioning hole 21; the switching element 4 is provided with an arc-shaped guide groove 42; the guide protrusion 31 passes through the arc-shaped guide groove 42 and is connected with the positioning hole 21.

[0059] The guide protrusion 31 on the base 3 or the sealing element 2 provides guidance and positioning for other elements during connection, thereby ensuring the accuracy and stability of the connection. The positioning hole 21 on the sealing element 2 or the base 3 is used to cooperate with the guide protrusion 31 to achieve precise positioning between elements.

[0060] The switch element 4 is provided with an arc-shaped guide groove 42, so that the guide protrusion 31 can smoothly pass through the arc-shaped guide groove 42, providing convenience for the subsequent connection action. The connection structure realizes stable connection and effective cooperation between parts through the cooperation of the guide protrusion 31 and the arc-shaped guide groove 42, and the connection with the positioning hole 21. The connection structure has stability and can ensure accurate connection between parts. The cooperation between parts makes the whole structure more perfect and effective in function, improving the performance and efficiency of the equipment. The design of the connection structure makes installation and maintenance more simple and convenient, reducing the cost and difficulty of use.

[0061] Please refer to Figures 1-11 In some embodiments, the housing 1 is provided with a positioning column 14 in the accommodation space, and the sealing element 2, the base 3 and the switch element 4 are correspondingly provided with sealing element through holes 24, base through holes 34 and switch element through holes 43. The axis of the positioning column 14 coincides with the axes of the sealing element through holes 24, the base through holes 34 and the switch element through holes 43. In the accommodation space of the housing 1, a positioning column 14 is arranged. The function of the positioning column 14 is to ensure that the components inside the housing 1 can be accurately installed and positioned. It is usually designed as a firm and stable structure that can withstand the weight of the components and internal mechanical stress.

[0062] The sealing element 2 is designed with a sealing element through hole 24, which allows the positioning column 14 to pass through while maintaining the overall sealing. The base 3 is usually used to support and fix other internal components, and the selection of its structure and material needs to consider its carrying capacity and stability.

[0063] The switch element 4 is installed inside the housing 1 and is provided with a switch element through hole 43. The design of the switch element through hole 43 is also for the use of the positioning column 14, so that the switch element 4 can be accurately installed and positioned.

[0064] The axis of the positioning column 14 coincides with the axes of the sealing element through holes 24, the base through holes 34 and the switch element through holes 43, ensuring the accuracy and stability of component installation. The coinciding axes can simplify the installation process, reduce errors, and enhance the overall structure and functionality. Such design also makes the components inside the housing 1 form a coordinated system, improving the performance and reliability of the equipment.

[0065] Of course, in some embodiments, a through hole is formed in the middle of the positioning column 14, the hole wall of the positioning column 14 is connected with the atomization channel of the atomizer to be connected, realizing the gas connection of the atomization channel, that is, the through hole can be part of the atomization airway, and the circumferential side of the hole wall of the positioning column 14 is sealed relative to the atomization channel to avoid gas leakage.

[0066] Please refer to Figures 1-11In some embodiments, the inner wall of the shell 1 is provided with an inner positioning step 13, and the outer wall of the positioning column 14 is provided with an outer positioning step 11; the lower end edge of the sealing element 2 is positioned in contact with the outer positioning step 11 and the inner positioning step 13. On the inner wall of the shell 1, an inner positioning step 13 is designed. The function of this inner positioning step 13 is to provide accurate positioning and support, ensuring that other components such as the sealing element 2 can be accurately installed and maintained stable. The shape and size of the inner positioning step 13 need to be accurately designed according to actual needs to ensure the accuracy and stability of its cooperation with related components.

[0067] The outer wall of the positioning column 14 is provided with an outer positioning step 11. The main function of the outer positioning step 11 is to cooperate with the inner positioning step 13 on the inner wall of the shell 1 to form a clear boundary and positioning surface, so that the sealing element 2 is limited inside the shell 1. In addition, the outer positioning step can also enhance the overall strength and stability of the structure. The lower end edge of the sealing element 2 is positioned in contact with the outer positioning step 11 and the inner positioning step 13. Such design can ensure the accurate position of the sealing element 2 in the shell 1, avoiding its movement or deviation during use. At the same time, through the close cooperation with the inner positioning step 13 and the outer positioning step 11, good sealing performance can be guaranteed to prevent gas or liquid leakage.

[0068] Please refer to Figures 1-11 In some embodiments, the outer periphery of the sealing element 2 is provided with an outer circumferential corrugation 23, and the inner side of the sealing element through hole 24 of the sealing element 2 is provided with an inner circumferential corrugation 25. The outer periphery of the sealing element 2 is provided with an outer circumferential corrugation 23, mainly to enhance the sealing performance and durability of the sealing element 2. The structure of the outer circumferential corrugation 23 can provide certain elastic deformation ability when the sealing element 2 is subjected to pressure, so that it better adapts to different sealing surface shapes and sizes, thereby ensuring better sealing effect. In addition, these corrugations also help to disperse and relieve external pressure, reducing the risk of damage to the sealing element 2 due to stress concentration. The shape of the outer circumferential corrugation 23 is usually regular or irregular wave lines, and its depth and pitch are designed according to actual needs and working conditions. The existence of these corrugations enables the sealing element 2 to produce corresponding deformation under the action of external factors such as temperature and pressure, so as to maintain a good sealing state. The corrugations increase the surface area of the side, increase the surface contact area, and thus increase the side friction. The sealing element 2 is usually provided with through holes (i.e. sealing element through hole 24), which are for the passage of the positioning column 14. On the inner side of the sealing element through hole 24, an inner circumferential corrugation 25 is provided, which has a similar function to the outer circumferential corrugation 23, but is more for adapting to the specific environment and needs inside the through hole.

[0069] In some embodiments, an atomization device is provided, which has a liquid storage bottle as described above. The atomization device has the liquid storage bottle, and an atomizer detachably connected with the liquid storage bottle, and a liquid receiving hole is arranged on the upper portion of the atomizer, and the liquid receiving hole is aligned with the liquid outlet hole 411 of the liquid storage bottle, and the liquid outlet hole 411 of the liquid storage bottle is in liquid communication with the liquid receiving hole, and when the liquid storage bottle is in an open state, liquid flows from the liquid outlet hole 411 to the liquid receiving hole. Since the liquid storage bottle and the atomizer are arranged above and below, the aerosol generated by the atomization of the atomizer is output to the outside through the upper portion, that is, through the liquid storage bottle to the outside. In an embodiment, the shell 1 of the liquid storage bottle can be used as a suction nozzle for the user to suck, and an additional suction nozzle component is not required.

[0070] The atomizer is provided with a liquid storage portion and an atomization core, and the liquid storage portion is arranged around the atomization core. The liquid storage portion is provided with liquid storage cotton or a cavity.
