Description

Technical Field

[0001] The embodiments of the present application relate to the field of aerosol generation technology, and in particular to a liquid reservoir and an aerosol generating device. Background Art

[0002] The liquid reservoir of the aerosol generating device is usually filled from the side of the liquid reservoir away from the nozzle, and then the silicone seal and the base are installed to close the liquid storage chamber of the liquid reservoir. However, this filling method can usually only be used for one filling. When the liquid matrix in the liquid reservoir is consumed, it cannot be filled again. In addition, the liquid reservoir is generally placed with the nozzle facing upward. If the liquid is filled from the bottom of the liquid reservoir, the sealing performance requirements of the bottom silicone seal are high, and there is a risk of leakage. In addition, the silicone seal and base at the bottom of the liquid reservoir will compress the air during the installation process. The inability to exhaust will increase the air pressure in the liquid storage chamber, thereby causing liquid leakage during storage or transportation. Utility Model Content

[0059] In one embodiment of the present application, the first housing 11 has a first groove 119 , which is disposed on the inner side wall of the first air pipe 114 to guide the liquid matrix condensed in the first air pipe 114 .

In one embodiment of the present application, the number of the plug bodies 141 is two, and correspondingly, the number of the injection holes 131 is also two, and the liquid reservoir 1 is provided with two plug bodies 141. After injection, the two plug bodies 141 successively seal the two injection holes 131. When the first plug body 141 seals the first injection hole 131, the liquid reservoir 1 will discharge part of the air from the second injection hole 131, so that the gas in the first liquid storage chamber 111 is not too large. In one embodiment of the present application, the first sealing member 14 has a second through hole 144, and the first air pipe 114 and the second air pipe 121 are respectively plugged into the second through hole 144.

[0061] In one embodiment of the present application, the liquid reservoir 1 further comprises a second bracket 15 disposed at the closed end 113 of the first shell 11. The closed end 113 of the first shell 11 has a liquid outlet 115, and the second bracket 15 can rotate relative to the first shell 11 to open or close the liquid outlet 115. The liquid outlet 115 is located on the side of the first shell 11 facing the second bracket 15, and the second bracket 15 has a liquid flow channel 152. The first shell 11 can rotate between a first position and a second position relative to the second bracket 15. When the first shell 11 is in the first position, the liquid outlet 115 and the liquid flow channel 152 at least partially overlap, and the liquid matrix in the first liquid storage chamber 111 can flow out; when the first shell 11 is in the second position, the liquid outlet 115 and the liquid flow channel 152 are staggered, and the liquid matrix in the first liquid storage chamber 111 is prevented from flowing out.

[0063] In one embodiment of the present application, the liquid reservoir 1 includes a second sealing member 16 , the second bracket 15 defines a first accommodating cavity 153 , and the second sealing member 16 is disposed in the first accommodating cavity 153 .

[0064] In one embodiment of the present application, the second sealing member 16 has a first through hole 161 , and when the first housing 11 is in the first position relative to the second bracket 15 , the liquid outlet 115 , the first through hole 161 , and the liquid flow channel 152 at least partially overlap.

[0065] In one embodiment of the present application, a rib 162 is provided on one side of the second sealing member 16 facing the closed end 113 of the first housing 11 , and the rib 162 defines a travel-limiting groove from the first position to the second position.

[0067] In one embodiment of the present application, the second bracket 15 further includes at least one liquid conducting column 154 . The liquid conducting column 154 is hollow and has at least one liquid conducting hole 155 formed thereon.

[0068] In one embodiment of the present application, the number of the liquid-conducting columns 154 may be multiple, and the number of the liquid-conducting holes 155 corresponds to the number of the liquid-conducting columns 154. In one embodiment of the present application, the number of the liquid-conducting columns 154 is two, and when the liquid matrix in the liquid-conducting hole 155 of one of the liquid-conducting columns 154 flows out of the first liquid storage chamber 111, the air pressure in the first liquid storage chamber 111 decreases, and at this time, the external air can enter the first liquid storage chamber 111 through the liquid-conducting hole 155 of another liquid-conducting column 154, thereby preventing the liquid matrix in the first liquid storage chamber 111 from being unable to flow out due to the reduction in air pressure.

[0069] In one embodiment of the present application, the liquid conducting hole 155 is disposed on the side wall of the liquid conducting column 154.

The diameter of the liquid conducting hole 155 is smaller than the inner diameter of the hollow portion of the liquid conducting column 154, so that the liquid matrix flows out of the hollow portion of the liquid conducting column 154 at a slower speed, thereby preventing leakage of the liquid matrix.

[0070] In one embodiment of the present application, the aperture or diameter of the liquid guide hole 155 is 0.5mm-1.5mm. In one embodiment of the present application, the shape of the liquid guide hole 155 is a circular, elongated or other shaped opening, and the aperture or diameter of the liquid guide hole 155 is 0.5mm-1.5mm, so that the liquid guide hole 155 has a capillary effect, and when the liquid reservoir 1 is sucked by the user, the liquid matrix in the first liquid storage chamber 111 flows out; when the liquid reservoir 1 is not in a working state, the liquid guide hole 51 has a certain capillary effect on the liquid matrix therein, and the liquid matrix is ​​retained in the liquid guide hole 51, avoiding the continuous outflow of the liquid matrix when the liquid reservoir 1 is not working, thereby causing the liquid matrix to leak. In one embodiment of the present application, the aperture or diameter of the liquid guide hole 51 can be 0.5mm, 0.8mm, 1.0mm, 1.2mm, 15mm.

[0071] In one embodiment of the present application, the liquid guiding hole 155 is disposed on the side wall of the liquid guiding column 154 .
