The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0036] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms used in this specification are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0037] See also Figure 1-Figure 4 , the embodiment of the present application provides an aerosol generating device 100, which is roughly in the shape of a flat cylinder, and the aerosol generating device 100 includes a housing 1, a power supply 2 and a heating component 3. The housing 1 is provided with a heating chamber 11, a power supply chamber 12, a cleaning port 13 and a pressure relief port 14, the cleaning port 13 is connected to the heating chamber 11, and the pressure relief port 14 is connected to the power supply chamber 12. The power supply 2 is arranged in the power supply chamber 12. The heating component 3 is arranged in the heating chamber 11, and the heating component 3 is electrically connected to the power supply 2. By providing the cleaning port 13 connected to the heating chamber 11 in the housing 1, it is convenient for the user to clean the residue in the heating component 3 in time, keep the heating component 3 clean, and thus maintain the user's suction taste when using the aerosol generating product. Furthermore, by providing the pressure relief port 14 connected to the power supply chamber 12 in the housing 1, the pressure relief port 14 can discharge the gas in the power supply chamber 12, maintain the pressure balance inside and outside the power supply chamber 12, and prevent the housing 1 from expanding easily, so that the safety of the aerosol generating device 100 meets the user's requirements.

[0038] For the above case 1, see Figure 5The heating chamber 11 and the power chamber 12 are arranged in the shell 1, and the shell 1 has a proximal end and a distal end relative to each other. When the user inhales the aerosol generating product, the end of the shell 1 close to the user is the proximal end, and the end of the shell 1 away from the user is the distal end. Among them, the cleaning port 13 is arranged at the distal end of the shell 1. In order to prevent the gas from being generated when the power supply 2 is abnormal, the gas is discharged outward through the pressure relief port 14 to form an airflow rushing towards the user's face, and the pressure relief port 14 is arranged at the distal end of the shell 1.

[0039] In some embodiments, see Figure 2-Figure 4 In order to prevent the cleaning port 13 and the pressure relief port 14 from being exposed and causing an unsightly appearance, and to prevent foreign matter such as dust from entering the housing 1 through the cleaning port 13 or the pressure relief port 14, the aerosol generating device 100 also includes a cover assembly 4, which is detachably arranged on the housing 1, and the cover assembly 4 is covered on the cleaning port 13 and the pressure relief port 14, thereby isolating the cleaning port 13 and the pressure relief port 14 from the outside. When it is necessary to clean the heating component 3, the cover assembly 4 can be removed from the housing 1, so that the cleaning port 13 is exposed, which is convenient for cleaning the heating component 3. When pressure relief is required, the gas in the power supply cavity 12 uses its own pressure to open the cover assembly 4, so that the pressure relief port 14 is exposed, which is convenient for pressure relief. The cover assembly 4 also plays a decorative role, making the aerosol generating device 100 beautiful.

[0040] In some embodiments, see Figure 2 and Figure 6 In order to make the cover assembly 4 detachably arranged on the shell 1, the cover assembly 4 includes a first magnetic member 41, and the aerosol generating device 100 includes a second magnetic member 5. The second magnetic member 5 is fixed to the shell 1, and the cover assembly 4 is fixed to the shell 1 by the second magnetic member 5 and the first magnetic member 41 being attracted. Under the external force, the cover assembly 4 overcomes the attraction between the second magnetic member 5 and the first magnetic member 41 to separate the cover assembly 4 from the shell 1. As an example, one of the first magnetic member 41 and the second magnetic member 5 is a ferromagnetic metal, and the other of the first magnetic member 41 and the second magnetic member 5 is a magnetic element, that is, the first magnetic member 41 is a ferromagnetic metal, and the second magnetic member 5 is a magnetic element, so that the second magnetic member 5 is attracted to the first magnetic member 41, or the first magnetic member 41 is a magnetic element, and the second magnetic member 5 is a ferromagnetic metal, so that the first magnetic member 41 is attracted to the second magnetic member 5. Alternatively, as another example, both the first magnetic member 41 and the second magnetic member 5 are magnetic elements, so that the first magnetic member 41 and the second magnetic member 5 can be attracted to each other.

[0041] In some embodiments, see Figure 2 and Figure 6, the cover plate assembly 4 also includes an outer cover 42 and a first adhesive 43. The first adhesive 43 is disposed between the first magnetic member 41 and the outer cover 42, and the first adhesive 43 bonds the first magnetic member 41 to the outer cover 42. The aerosol generating device 100 also includes a second adhesive 6, which is disposed between the shell 1 and the second magnetic member 5, and the second adhesive 6 bonds the second magnetic member 5 to the shell 1. As an example, the first adhesive 43 and the second adhesive 6 are both double-sided adhesives, or are formed by curing one of adhesives such as hot melt adhesive, super glue, and metal glue.

[0042] In some embodiments, see Figure 3 and Figure 5 A receiving groove 15 is provided at the distal end of the shell 1, and the cleaning port 13 and the pressure relief port 14 are connected to the receiving groove 15. The receiving groove 15 is used to receive the cover assembly 4 to prevent the cover assembly 4 from protruding from the shell 1, so that the aerosol generating device 100 is beautiful as a whole.

[0043] In some embodiments, see Figure 3-Figure 6 , the housing 1 is provided with a positioning groove 16 on one side wall of the receiving groove 15, the positioning groove 16 is connected to the receiving groove 15, and a positioning protrusion 44 is provided at one end of the cover assembly 4, the positioning protrusion 44 is plugged into the positioning groove 16, and the cover assembly 4 can be rotated with the positioning groove 16 as the center, so that the cover assembly 4 covers the cleaning port 13 and the pressure relief port 14, or so that the cleaning port 13 and the pressure relief port 14 are exposed. When the power cavity 12 needs to be depressurized, the gas generates an airflow to impact the cover assembly 4, so that the cover assembly 4 rotates and opens with the positioning groove 16 as the center, so that the pressure relief port 14 exposes the exhaust gas, and prevents the cover assembly 4 from being bounced off by the gas impact. As an example, the positioning protrusion 44 is provided at one end of the first magnetic suction member 41 or one end of the outer cover member 42. It should be noted that the positioning protrusion 44 is detachably plugged into the positioning groove 16. When the heating component 3 needs to be cleaned, the positioning protrusion 44 can be pulled out from the positioning groove 16, thereby removing the cover assembly 4 from the housing 1. In other embodiments, in order to avoid the cover assembly 4 from being lost, when the heating assembly 3 needs to be cleaned, the cover assembly 4 is rotated around the positioning groove 16 so that the angle b between the cover assembly 4 and the bottom of the receiving groove 15 is equal to or greater than 90 degrees, so that the cover assembly 4 does not interfere with the user's cleaning of the heating assembly 3 through the cleaning port 13, and the user does not need to remove the cover assembly 4 from the shell 1, thereby avoiding the cover assembly 4 from being lost.

[0044] In some embodiments, see Figure 3 and Figure 6In order to facilitate the user to open the cover assembly 4, a buckle portion 45 is provided at the other end of the cover assembly 4. When the cover assembly 4 is received in the receiving groove 15 and the cover assembly 4 covers the cleaning port 13 and the pressure relief port 14, there is a gap a between the buckle portion 45 and the other side wall of the receiving groove 15. The gap a facilitates the user to reach in and buckle the buckle portion 45, thereby facilitating the user to open the cover assembly 4. As an example, the buckle portion 45 is formed by one end of the outer cover 42 protruding from the other end of the first magnetic member 41. As another example, the buckle portion 45 can also be formed by the other end of the first magnetic member 41 being recessed in one end of the outer cover 42.

[0045] It is understood that in some embodiments, see Figure 7 The cover plate assembly 4 is not limited to the above structure, and the cover plate assembly 4 can also be other structures. For example, the cover plate assembly 4 includes a first cover plate 48 and a second cover plate 49. The first cover plate 48 and the second cover plate 49 are both removable and arranged on the shell 1. The first cover plate 48 covers the cleaning port 13, and the second cover plate 49 covers the pressure relief port 14.

[0046] In some embodiments, the first cover plate 48 includes a first cover plate body and a third magnetic member, the third magnetic member is bonded to the first cover plate body by one of adhesives such as double-sided tape, hot melt adhesive, metal glue, etc., the aerosol generating device 100 also includes a fourth magnetic member, the fourth magnetic member is bonded to the shell 1 by one of adhesives such as double-sided tape, hot melt adhesive, metal glue, etc., the third magnetic member and the fourth magnetic member are attracted to each other, so that the first cover plate is set on the shell 1, when the first cover plate 48 is acted on by an external force, the first cover plate 48 overcomes the attraction between the third magnetic member and the fourth magnetic member, so that the first cover plate 48 is separated from the shell 1, so that the first cover plate 48 is removed from the shell 1 to open the cleaning port 13. As an example, one of the third magnetic member and the fourth magnetic member is a ferromagnetic metal, and the other of the third magnetic member and the fourth magnetic member is a magnetic element, or both the third magnetic member and the fourth magnetic member are magnetic elements. And / or, the second cover plate 49 includes a second cover plate body and a fifth magnetic member, the fifth magnetic member is bonded to the second cover plate body by one of the adhesives such as double-sided tape, hot melt adhesive, metal glue, etc., the aerosol generating device 100 also includes a sixth magnetic member, the sixth magnetic member is bonded to the shell 1 by one of the adhesives such as double-sided tape, hot melt adhesive, metal glue, etc., the fifth magnetic member and the sixth magnetic member are attracted to each other, so that the second cover plate 49 is set on the shell 1, when the second cover plate 49 is acted on by an external force, the second cover plate 49 overcomes the attraction between the fifth magnetic member and the sixth magnetic member, so that the second cover plate 49 is separated from the shell 1, so that the second cover plate 49 is removed from the shell 1 to open the pressure relief port 14. As an example, one of the fifth magnetic member and the sixth magnetic member is a ferromagnetic metal, and the other of the fifth magnetic member and the sixth magnetic member is a magnetic element, or both the fifth magnetic member and the sixth magnetic member are magnetic elements.
