[0008] In one embodiment, the liquid outlet is arranged beside the ventilation port, and a ventilation part is arranged at a position of the liquid storage tank away from the liquid outlet. The ventilation part includes a ventilation groove, and the other end of the ventilation pipe away from the ventilation port extends into the ventilation groove and is connected with the airflow of the ventilation groove.

[0009] In one embodiment, the liquid storage bin includes a bin body and a cover body that are fixedly connected, the liquid outlet and the ventilation port are arranged on the cover body, and the ventilation groove is arranged at the bottom of the bin body away from the cover body.

[0010] In one embodiment, the ventilation part includes a fixing member, one end of which is arranged in the ventilation groove, and the other end of the fixing member is arranged in the ventilation pipe. An airway is formed between the ventilation pipe and the fixing member, and the airway is respectively connected to the liquid storage chamber and the air flow inside the ventilation pipe. The size of the airway is configured to allow gas to pass through but hinder liquid from passing through by capillary action.

[0011] In one embodiment, the fixing member includes a fixing seat and a fixing rod. The fixing seat is arranged in the ventilation groove. The fixing rod is arranged on the fixing seat and inserted into the ventilation pipe. The end of the ventilation pipe away from the ventilation port abuts against the fixing seat.

[0012] A connecting groove is provided on the fixing member, and the ventilation pipe and the connecting groove are combined to form an airway. The connecting groove includes a first groove section and a second groove section that are connected to each other. The first groove section is provided on the fixing seat, and the second groove section is a through groove opened along the extension direction of the fixing rod.

[0013] In one embodiment, at least two air passages are formed between the ventilation duct and the fixing member.

[0014] In one embodiment, the cover body is provided with an annular groove and a straight groove, the annular groove is provided on a side of the cover body away from the bin body, and the ventilation port is connected with the annular groove;

[0015] The straight groove is communicated with the annular groove, and the straight groove extends toward the edge of the cover body to form a through groove.

[0016] In one of the embodiments, a limit seat is provided on one side of the cover body facing the liquid storage chamber, and the ventilation pipe is fixedly connected to the limit seat.

[0033] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

Among them, the axial direction, circumferential direction and radial direction together constitute the three orthogonal directions of the columnar object. It is worth noting that the "end" appearing in the terms "proximal end", "distal end", "one end", "the other end", "first end", "second end", "initial end", "end", "two ends", "free end", "upper end", "lower end", etc. is not limited to the end, endpoint or end face, but also includes a portion extending from the end, endpoint, or end face on the element to which the end, endpoint, or end face belongs, for an axial distance and / or radial distance. The above definition is only for the convenience of expression and cannot be understood as a limitation of the present application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] In the related art, the liquid storage parts of the electronic atomization device usually do not have the function of maintaining air pressure balance with the outside world. After a period of use, as the aerosol matrix is ​​consumed, the air pressure difference between the inside and outside of the liquid storage parts becomes larger and larger, which can easily lead to problems such as poor liquid supply and core sticking. In addition, the seal may be deformed due to air pressure extrusion, thereby reducing the sealing performance of the liquid storage part and causing liquid leakage. Or under the action of the air pressure difference, the liquid may become easier to flow, or the surface tension may decrease, making the liquid more likely to leak.

[0039] An embodiment of the present application provides a liquid storage component, which relates to the field of electronic atomization technology and is mainly used in an electronic atomization device.

[0040] like Figure 1 , Figure 5 As shown, the liquid storage component includes a liquid storage tank 10 and a ventilation component 300. A liquid storage cavity 101 is formed in the liquid storage tank 10, and the liquid storage cavity 101 is used to store the aerosol generating matrix. The liquid storage tank 10 is provided with a liquid outlet 210 and a ventilation port 220 connected to the outside; the ventilation component 300 includes a ventilation pipe 310, one end of the ventilation pipe 310 is connected to the ventilation port 220, and the other end of the ventilation pipe 310 is connected to the liquid storage cavity 101 by airflow.

[0041] When the liquid storage member provided in this embodiment is installed in an electronic atomization device for use, the liquid storage chamber 101 of the liquid storage tank 10 must first be filled with an aerosol-generating matrix. This step is the basis for ensuring that the subsequent atomization process can proceed smoothly. When the user starts and operates the electronic atomization device for use, the aerosol-generating matrix pre-filled in the liquid storage chamber 101 will be sucked out by the user through the liquid outlet 210. These matrices are then atomized by the electronic atomizer 600 in the electronic atomization device and processed into aerosols for inhalation by the user.

[0042] With the continuous use of the electronic atomization device, the aerosol-generating matrix in the liquid storage tank 10 will gradually be consumed and reduced. When the matrix in the liquid storage chamber 101 is reduced to a certain extent, resulting in a corresponding decrease in the internal air pressure, the airflow of the outside atmosphere can smoothly pass through the specially opened ventilation port 220 and enter the ventilation channel on the ventilation component 300. This airflow will then further enter the interior of the liquid storage tank 10 to automatically replenish the reduced matrix. The "replenishment" here mainly refers to the balance of air pressure, rather than directly adding the matrix. Through such a design, the air pressure in the liquid storage tank 10 can be effectively maintained consistent with the atmospheric pressure.

[0043] This design not only brings multiple benefits: First, it can ensure that the liquid storage tank 10 will not be deformed unnecessarily due to the negative pressure formed in the liquid storage chamber 101, thereby ensuring the stability and durability of the overall structure of the liquid storage tank 10. Secondly, the stable air pressure environment helps to maintain the sealing performance of the liquid storage tank 10, effectively avoiding leakage problems caused by poor sealing, and ensuring the safety and hygiene of use. Finally, by maintaining the stability of the air pressure in the liquid storage chamber 101, it can also ensure the smooth supply of the aerosol generation matrix, thereby ensuring that the electronic atomization device can continuously and stably generate high-quality aerosols, bringing users a better quality and stable atomization experience, thereby greatly improving the user's usage experience and overall experience.

[0044] In some embodiments, the liquid outlet 210 is arranged beside the ventilation port 220, and the liquid storage tank 10 is provided with a ventilation part 400 at a position away from the liquid outlet 210, and the ventilation part 400 includes a ventilation groove 410, and the other end of the ventilation pipe 310 away from the ventilation port 220 extends into the ventilation groove 410 and is connected with the ventilation groove 410 by air flow. By keeping a certain distance between the end of the ventilation pipe 310 extending into the liquid storage chamber 101 and the liquid outlet 210, and ensuring that it can achieve effective air flow communication with the ventilation groove 410 after extending into the ventilation groove 410, such a design is used to enable the ventilation channel to separate the delivery position of atmospheric air to the liquid storage chamber 101 from the liquid outlet 210 during the process of the user extracting the aerosol generating matrix from the liquid outlet 210. This separation measure is extremely critical because it effectively prevents the aerosol generating matrix extracted from the liquid outlet 210 from mixing with the airflow just introduced. Once the two are mixed, it is likely to have an adverse effect on the final atomization effect, resulting in a decrease in the quality of the generated aerosol, thus affecting the user experience and satisfaction.

[0045] In some embodiments, the liquid storage tank 10 includes a tank body 100 and a cover body 200 that are fixedly connected, the liquid outlet 210 and the ventilation port 220 are arranged on the cover body 200, and the ventilation groove 410 is arranged on the bottom of the tank body 100 away from the cover body 200. When the liquid storage part is in use, the position of the tank body 100 in the vertical direction is higher than the cover body 200. Such a design helps to optimize the distribution and flow of the aerosol generating matrix in the liquid storage chamber 101. Specifically, as the aerosol generating matrix in the liquid storage chamber 101 gradually decreases with use, the liquid level in the liquid storage chamber 101 will drop accordingly. At this time, a cavity will first be formed near the bottom of the tank body 100 and the position where the ventilation groove 410 is located to prevent the aerosol generating matrix from entering the other end of the ventilation duct 310 away from the ventilation port 220 and causing leakage.

[0046] When the airflow enters from the ventilation duct 310 and flows through the ventilation groove 410, it will directly enter the cavity instead of passing through the aerosol generating matrix. Such airflow path selection effectively avoids bubbles that may be generated when the airflow passes through the aerosol generating matrix, and also avoids the mixing of the aerosol generating matrix and the air. Such a design not only helps to dynamically maintain the pressure in the liquid storage tank 10 consistent with the atmospheric pressure, but more importantly, it ensures the quality of the aerosol generating matrix and avoids the problem of poor atomization effect caused by bubbles or mixing. Ultimately, such a design provides users with a better user experience and ensures the stability and reliability of each use.

[0047] like Figure 2 As shown, in some embodiments, the ventilation part 400 includes a fixing member 420, one end of which is disposed in the ventilation groove 410, and the other end of the fixing member 420 is disposed in the ventilation duct 310, and an airway 401 is formed between the ventilation duct 310 and the fixing member 420, and the airway 401 is respectively connected to the liquid storage chamber 101 and the internal airflow of the ventilation duct 310, and the size of the airway 401 is configured to allow gas to pass through but hinder the passage of liquid by capillary action; specifically, the size of the airway 401 is set to be small enough to only allow gas to pass through, while being able to effectively hinder the passage of liquid. Such a design cleverly avoids the risk that the aerosol-generating matrix in the liquid storage chamber 101 may flow out of the ventilation channel during the ventilation process, thereby greatly reducing the possibility of leakage.

[0048] In some embodiments, the fixing member 420 includes a fixing seat 421 and a fixing rod 422. The fixing seat 421 is disposed in the ventilation groove 410, and its shape and size are strictly designed to ensure a close fit with the ventilation groove 410, thereby preventing leakage of gas or liquid. The fixing rod 422 is disposed on the fixing seat 421 and is tightly connected to the inside of the ventilation duct 310 in some manner (such as plug-in, threaded connection, etc.). The end of the ventilation duct 310 away from the ventilation port 220 abuts against the fixing seat 421. Such a design not only enhances the connection stability between the ventilation duct 310 and the fixing member 420, but also ensures reliable communication between the ventilation channel and the airway 401 on the fixing member 420.

[0049] A connecting groove 430 is provided on the fixing member 420, and the ventilation duct 310 and the connecting groove 430 together form an airway 401. The connecting groove 430 includes a first groove section 431 and a second groove section 432 that are connected to each other. The first groove section 431 is provided on the fixing seat 421, and the second groove section 432 is a through groove opened along the extension direction of the fixing rod 422, so as to ensure the stable passage of airflow through the airway 401.

[0050] In some embodiments, at least two air passages 401 are formed between the ventilation duct 310 and the fixing member 420; by setting at least two air passages 401 between the ventilation duct 310 and the fixing member 420, this embodiment not only achieves rapid passage of airflow, but also improves ventilation efficiency, gas utilization and overall performance.

[0051] like Figure 3 As shown, in some embodiments, the cover 200 is provided with an annular groove 230 and a straight groove 240, the annular groove 230 is provided on the side of the cover 200 away from the chamber 100, the ventilation port 220 is connected with the annular groove 230; the straight groove 240 is connected with the annular groove 230, and the straight groove 240 extends to the edge of the cover 200 to form a through groove, one end of which is connected with the outside atmosphere; by extending and bending the airflow path between the ventilation port 220 and the outside atmosphere, the airflow velocity is buffered. In this way, when the gas enters the liquid storage chamber 101, it can maintain a stable and uniform state, avoiding unnecessary disturbance of the liquid or aerosol generating matrix in the liquid storage chamber 101 due to excessively fast or violent airflow.

[0052] In addition, this design also cleverly prevents foreign matter or airflow with dirt from directly passing through the ventilation port 220 and flowing through the ventilation channel into the liquid storage chamber 101. In the process of airflow passing through the annular groove 230 and the straight groove 240, these potential pollutants will be effectively blocked out, thereby protecting the various components of this embodiment from the risk of contamination.

[0053] In some embodiments, a limit seat 320 is provided on one side of the cover body 200 facing the liquid storage chamber 101 , and the ventilation duct 310 is fixedly connected to the limit seat 320 , so as to limit the installation position of the ventilation channel and ensure the reliability of the cooperation between the ventilation channel and the cover body 200 .

[0054] like Figure 4 As shown, in some embodiments, the liquid storage part further includes a detachably connected sealing sleeve 500, which is used to seal the liquid outlet 210 and the ventilation port 220; when the liquid storage part needs to be temporarily stored or transported, the user only needs to simply install the sealing sleeve 500 to the corresponding position to achieve simultaneous sealing of the liquid outlet 210 and the ventilation port 220. Such a design not only simplifies the operation steps, but also ensures that the sealed cavity can be fully sealed, thereby effectively preventing the leakage of liquid or gas.

[0055] like Figure 6 As shown, the embodiment of the present application also provides an electronic atomization device, including an electronic atomizer 600 and the aforementioned liquid storage component, the liquid storage component is installed on the electronic atomizer 600, and its main function is to stably and continuously supply the aerosol generation matrix to the electronic atomizer 600. This design not only ensures that the electronic atomization device can work continuously and efficiently, but also provides users with a more convenient and comfortable use experience.
