It is expressly understood that any of the features, structures, or characteristics described in connection with an embodiment can be included in a different embodiment.

[0029] In order to make the technical personnel in the art better understand the scheme of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings.

[0030] An aerosol generating device is provided according to an embodiment of the present application, which adopts the technical solutions as follows:

[0031] As shown in FIGS. 1-8, an aerosol generating device according to an embodiment of the present application includes: Figure 1 to FIG. 8, an aerosol generating device according to an embodiment of the present application includes: Figure 6

[0032] ​An atomization core assembly 100;

[0033] A liquid bottle 200 for storing aerosol substrate;

[0034] A liquid adding assembly 300, which comprises a housing 1 for connecting the atomization core assembly 100 and the liquid bottle 200, and a liquid injection valve 2 arranged in the housing 1, and pressing the liquid injection valve 2 makes the aerosol substrate in the liquid bottle 200 injected into the atomization core assembly 100.

[0035] The present application injects the aerosol substrate into the atomization core assembly 100 by pressing the liquid injection valve 2, so that the user can quickly and accurately supplement the aerosol substrate for the atomization core assembly 100, without waiting for the aerosol substrate to flow naturally, reducing the risk of liquid leakage, thereby improving the overall use efficiency, providing a convenient liquid adding method, and improving the user's use experience.

[0036] Furthermore, the prior art also accelerates the liquid adding speed by extruding the liquid bottle, but the extrusion of the liquid bottle cannot effectively control the injection amount of the aerosol substrate injected into the atomization core assembly, which not only causes waste, but also causes the excess aerosol substrate to drip along the suction nozzle, causing pollution, and the present application injects the aerosol substrate into the atomization core assembly 100 by using the liquid injection valve 2, and pressing the liquid injection valve 2 once can inject 0.5-1.0ml of aerosol substrate, so that the user can accurately control the oil amount according to the demand, avoid waste, reduce the risk of spilling and leaking of the liquid bottle 200 during the oil injection process, and ensure the cleanliness of the environment and the safety of the user.

[0037] As shown in FIG. 1, the liquid bottle 200 is arranged on the housing 1 of the liquid adding assembly 300, and the liquid injection valve 2 is arranged in the housing 1. Figure 4 to FIG. 4, the liquid injection valve 2 is arranged in the housing 1 of the liquid adding assembly 300, and the liquid injection valve 2 is arranged in the housing 1. Figure 5As shown, in one embodiment, the shell 1 is provided with a first channel 11 communicating with the atomization core assembly 100, a second channel 12 communicating with the liquid bottle 200, and a liquid injection cavity 13 communicating with the first channel 11 and the second channel 12 respectively, the liquid injection valve 2 is arranged in the liquid injection cavity 13, and a buffer 3 is further arranged in the liquid injection cavity 13. Pressing the liquid injection valve 2 allows the aerosol substrate in the liquid bottle 200 to be injected into the atomization core assembly 100 through the buffer 3. The buffer 3 can prevent the aerosol substrate from flowing into the atomization core assembly 100 naturally when the liquid bottle 200 is inverted, prevent too much aerosol substrate from being injected, avoid waste, reduce the risk of liquid leakage, and also play a role in pressure reduction to prevent the pressure of the aerosol substrate injected into the atomization core assembly from being too high, thereby avoiding the aerosol substrate from being squeezed out of the atomization core assembly 100 to cause oil leakage, and the buffer 3 can also prevent backflow to avoid the aerosol substrate heated by the atomization core assembly 100 from flowing back into the liquid bottle 200, thereby causing the aerosol substrate in the liquid bottle 200 to be contaminated and affecting the use effect.

[0038] Further, one end of the first channel 11 near the liquid injection cavity 13 is tapered, and the diameter gradually decreases in the direction of the liquid injection cavity 13 towards the atomization core assembly 100, and the diameter of the first channel 11 is smaller than the diameter of the liquid injection cavity 13, which is beneficial to the aerosol substrate passing through the buffer 3 to enter the atomization core assembly 100 during liquid injection, preventing backflow and avoiding the aerosol substrate heated by the atomization core assembly 100 from flowing back into the liquid bottle 200, thereby causing the aerosol substrate in the liquid bottle 200 to be contaminated and affecting the use effect.

[0039] As shown in the accompanying drawings, Figure 3 to the accompanying drawings, Figure 4 As shown, in one embodiment, the atomization core assembly 100 includes a liquid absorbing cotton 101, and the first channel 11 is connected with the liquid absorbing cotton 101. Pressing the liquid injection valve 2 allows the aerosol substrate entering the atomization core assembly 100 to be directly injected into the liquid absorbing cotton 101, which can well absorb the aerosol substrate, prevent the aerosol substrate from dripping or evaporating along the suction nozzle, cause pollution and waste, reduce the risk of pouring and leakage of the liquid bottle 200 during oil injection, and ensure the cleanliness of the environment and the safety of the user.

[0040] Further, the buffer 3 and the liquid absorbing cotton 101 are respectively made of high molecular cotton, which has large liquid absorption capacity, fast liquid absorption speed, can be reused, and is low in cost.

[0041] As shown in the accompanying drawings, Figure 3 to the accompanying drawings, Figure 4and attached Figure 6 As shown in the drawings, in one embodiment, the liquid adding assembly 300 further comprises a liquid injection sleeve 4, the liquid injection valve 2 and the buffer 3 are arranged in the liquid injection sleeve 4, the liquid injection cavity 13 is arranged on the liquid injection sleeve 4, the liquid injection sleeve 4 is provided with a liquid inlet hole 41 which communicates with the liquid injection cavity 13, and the liquid inlet hole 41 is arranged between the liquid injection valve 2 and the buffer 3. The liquid injection sleeve 4 provides a stable liquid injection cavity 13, ensures smooth movement of the liquid injection valve 2 in the liquid injection cavity 13, and ensures that the user can quickly replenish the aerosol substrate for the atomizing core assembly 100, thereby improving the overall use efficiency, providing a convenient liquid adding method, and improving the user's use experience.

[0042] Further, in the liquid injection cavity 13, 1.0 ml of aerosol substrate can be stored between the liquid injection valve 2 and the buffer 3, that is, 1.0 ml of aerosol substrate flows from the liquid bottle 200 through the liquid inlet hole 41 into the liquid injection cavity 13, ensuring that 0.5-1.0 ml of aerosol substrate can be injected into the atomizing core assembly 100 by pressing the liquid injection valve 2 once, the user can accurately control the oil amount according to the needs, avoid waste, reduce the risk of spilling and leakage of the liquid bottle 200 during oil injection, and ensure the cleanliness of the environment and the safety of the user.

[0043] Further, since the liquid inlet hole 41 is arranged between the liquid injection valve 2 and the buffer 3, the pressing frequency should be appropriately reduced when pressing the liquid injection valve 2, and the time for the aerosol substrate to pass through the buffer 3 is given, the lower the frequency, the higher the aerosol substrate injected into the atomizing core assembly 100 at a time, reaching 1.0 ml.

[0044] As shown in the drawings, Figure 1 to the drawings Figure 4 As shown in the drawings, in one embodiment, the liquid adding assembly 300 further comprises a key 5, and the key 5 is fixedly connected with the liquid injection valve 2. The user can press the liquid injection valve 2 through the key 5, the user can quickly and accurately replenish the aerosol substrate for the atomizing core assembly 100, without waiting for the aerosol substrate to flow naturally, thereby reducing the risk of liquid leakage, improving the overall use efficiency, providing a convenient liquid adding method, and improving the user's use experience.

[0045] As shown in the drawings, Figure 1 to the drawings Figure 4 As shown in the drawings, in one embodiment, the liquid adding assembly 300 further comprises a reset spring 51, and the two ends of the reset spring 51 abut against the liquid injection sleeve 4 and the key 5, respectively. When the pressing on the key 5 is removed, the key 5 can be automatically reset under the action of the reset spring 51, ensuring that the liquid injection valve 2 remains closed when not in use, avoiding accidental leakage and evaporation of the aerosol substrate.

[0046] Further, the resilience of the liquid injection valve 2 is mainly from the reset spring 51, and the buffer 3 can also assist the resilience. The buffer 3 made of high polymer cotton has a certain resilience. The user presses the liquid injection valve 2 through the button 5. The liquid injection valve 2 compresses the buffer 3, and the aerosol substrate is extruded through the buffer 3 under the extrusion of the liquid injection valve 2. When the pressing on the button 5 is removed, the buffer 3 provides a certain resilience, and the liquid injection valve 2 and the button 5 reset. At the same time, since the liquid injection valve 2 extrudes the buffer 3, if backflow occurs, one end of the tapered first channel 11 will guide the backflow of the aerosol substrate to the buffer 3, so as to be absorbed by the buffer 3, avoiding the aerosol substrate heated by the atomizing core assembly 100 from flowing back to the liquid bottle 200, thereby avoiding the aerosol substrate in the liquid bottle 200 from being contaminated, and affecting the use effect.

[0047] As shown in the accompanying drawings, Figure 2 to the accompanying drawings, Figure 3 In one embodiment, the liquid bottle 200 is provided with a bracket 6, and the liquid bottle 200 and the shell 1 are fixed on the bracket 6, respectively. The bracket 6 can stabilize the liquid bottle 200 and the shell 1, prevent displacement, and ensure that the user can press the liquid injection valve 2 through the button 5 to quickly and accurately supplement the aerosol substrate for the atomizing core assembly 100.

[0048] As shown in the accompanying drawings, Figure 2 to the accompanying drawings, Figure 3 In one embodiment, the liquid bottle 200 and the bracket 6 are further provided with a sealing piece 7, and the sealing piece 7 is partially inserted into the liquid bottle 200. The sealing piece 7 can seal the liquid bottle 200 and the bracket 6, prevent the aerosol substrate from flowing out from the gap between the liquid bottle 200 and the bracket 6 when the aerosol generating device is inverted, avoid waste, reduce the risk of pouring and leakage of the liquid bottle 200 during oil injection, reduce the number of cleaning and maintenance, and ensure the cleanliness of the environment and the safety of the user.

[0049] As shown in the accompanying drawings, Figure 2 to the accompanying drawings, Figure 4As shown, in one of the embodiments, a protection tube 71 is further arranged in the sealing member 7, one end of the protection tube 71 is inserted into the sealing member 7, and the other end of the protection tube 71 is inserted into the shell 1. The second channel 12 is partially arranged in the protection tube 71, and the protection tube 71 provides a stable second channel 12, ensuring that the aerosol substrate in the liquid bottle 200 is smoothly supplemented into the liquid injection cavity 13, ensuring that the user can quickly supplement the aerosol substrate for the atomization core assembly 100, thereby improving the overall use efficiency, providing a convenient liquid supplementing method, and improving the user's use experience.

[0050] Further, the liquid injection sleeve 4 and the protection tube 71 are made of stainless steel or other materials, which are corrosion-resistant and ensure the stability of the liquid injection cavity 13.

[0051] As shown in the accompanying drawings Figure 1 to the accompanying Figure 4 As shown, in one of the embodiments, the aerosol generating device further comprises a housing 8, and the housing 8 is provided with an opening 81 for the liquid supplementing assembly 300 to leak out. The opening 81 facilitates the leakage of the button 5 in the liquid supplementing assembly 300, making it easy for the user to press the button 5 without complicated operation. The user can quickly and accurately supplement the aerosol substrate for the atomization core assembly 100, providing a convenient liquid supplementing method and improving the user's use experience.

[0052] When supplementing liquid, the aerosol generating device is first inverted, at which time the aerosol substrate in the liquid bottle 200 flows into the liquid injection cavity 13 through the second channel 12 and the liquid inlet hole 41 under the action of gravity. The user presses the button 5, which drives the liquid injection valve 2 to move towards the atomization core assembly 100. The liquid injection valve 2 extrudes the aerosol substrate in the liquid injection cavity 13, and the aerosol substrate is injected into the liquid absorbing cotton 101 in the atomization core assembly 100 after passing through the buffer member 3 and the first channel 11, thereby completing the liquid supplementing. Then, the button 5 is released, and the button 5 can be automatically reset under the action of the reset spring 51. After that, the aerosol generating device is upright, and aerosol can be inhaled.
