[0030] The present application embodiment provides an atomizer, such as Figure 1 、 6 As shown in Figures 9 to 9, the atomizer includes: a shell 1, a fixing part 2 and a sealing part 3; the shell 1 has a liquid storage tank 10, and the wall of the shell 1 is provided with a liquid injection hole 11 connected to the liquid storage tank 10, the sealing part 3 is movably provided on the shell 1 and seals the liquid injection hole 11, and the fixing part 2 is movably provided on the shell 1 and fixes the sealing part 3.

[0031] The working principle of the atomizer provided in the embodiment of the present application is as follows: Figures 7 to 9 When it is necessary to inject an aerosol-generating medium into the liquid storage tank 10, first move the fixing member 2 to cancel the fixing of the fixing member 2 on the sealing member 3; then, move the sealing member 3 to cancel the sealing of the sealing member 3 on the injection hole 11; then, use the injection tool to inject the aerosol-generating medium into the liquid storage tank 10 through the injection hole 11. After the injection is completed, pull out the injection tool; then, move and reset the sealing member 3 so that the sealing member 3 seals the injection hole 11; finally, move and reset the fixing member 2 so that the fixing member 2 fixes the sealing member 3.

[0032] The beneficial effects of the nebulizer provided by the embodiment of the present application are as follows: a liquid injection hole 11 is opened on the shell 1, and the liquid injection hole 11 is sealed by the sealing member 3, and the sealing member 3 is fixed by the fixing member 2, so that when the aerosol generating medium is replenished into the liquid storage tank 10, there is no need to disassemble the shell 1, and only the fixing member 2 and the sealing member 3 need to be moved in sequence, which is simple to operate and not prone to leakage; in addition, the setting of the fixing member 2 can prevent children from accidentally touching the nebulizer and opening the sealing member 3, further avoiding leakage of the aerosol generating medium and avoiding accidental ingestion, thereby improving the safety of the nebulizer.

[0033] like Figures 3 to 5As shown, further, a slide groove 12 is provided on the shell 1, and a fixing groove 31 is provided on the side of the seal 3 adjacent to the slide groove 12. The fixing member 2 includes a fixing portion 21 and a limiting portion 22. The fixing portion 21 is slidably connected to the slide groove 12 and plugged into the fixing groove 31. The side wall of the limiting portion 22 abuts against the shell 1.

[0034] In this embodiment, see Figure 7 、 8 When it is necessary to inject the aerosol generating medium into the liquid storage tank 10, pull the limiting part 22, and the limiting part 22 drives the fixing part 21 to slide in the slide groove 12 in the direction away from the fixing groove 31, so that the fixing part 21 is out of the fixing groove 31 to cancel the fixation of the sealing member 3; after the injection is completed, push the limiting part 22, and the limiting part 22 drives the fixing part 21 to move in the slide groove 12 toward the fixing groove 31, so that the fixing part 21 is inserted into the fixing groove 31 until the side wall of the limiting part 22 abuts against the shell 1 to achieve the fixation of the sealing member 3.

[0035] In this embodiment, the limiting portion 22 is provided to facilitate the user to move the fixing member 2 , so as to avoid the situation where the fixing member 2 is completely inserted into the fixing slot 31 and cannot be removed.

[0036] like Figure 4 As shown, further, a protrusion 23 is provided at one end of the fixing portion 21 away from the limiting portion 22, and the total thickness of the protrusion 23 and the fixing portion 21 is greater than the groove width of the slide groove 12 and smaller than the groove width of the fixing groove 31, and the fixing portion 21 is interference fit with the slide groove 12.

[0037] In this embodiment, the total thickness of the protrusion 23 and the fixing portion 21 is greater than the groove width of the slide groove 12, preventing the user from dragging the entire fixing portion 21 out of the slide groove 12 when moving the fixing member 2, thereby preventing the fixing member 2 from being lost; the total thickness of the protrusion 23 and the fixing portion 21 is less than the groove width of the fixing groove 31, to ensure that the fixing portion 21 can be inserted into the fixing groove 31; the fixing portion 21 and the slide groove 12 have an interference fit, preventing the atomizer from being shaken and causing the fixing member 2 to move.

[0038] like Figure 3 As shown, further, the housing 1 is provided with a first accommodating groove 13 communicating with the sliding groove 12 , and the limiting portion 22 is placed in the first accommodating groove 13 and abuts against the groove wall of the first accommodating groove 13 .

[0039] In this embodiment, when it is necessary to inject an aerosol generating medium into the liquid storage tank 10, the limiting part 22 is pulled, and the limiting part 22 disengages from the first accommodating groove 13. The limiting part 22 drives the fixing part 21 to slide in the direction away from the fixing groove 31 in the sliding groove 12, so that the fixing part 21 disengages from the fixing groove 31 to cancel the fixation of the sealing member 3; after the injection is completed, the limiting part 22 is pushed, and the limiting part 22 drives the fixing part 21 to move in the direction of the fixing groove 31 in the sliding groove 12, so that the fixing part 21 is inserted into the fixing groove 31 until the side wall of the limiting part 22 abuts against the groove wall of the first accommodating groove 13 to achieve the fixation of the sealing member 3.

[0040] In this embodiment, the limiting portion 22 is placed in the first receiving groove 13 to prevent the limiting portion 22 from protruding from the housing 1 , thereby preventing the fixing member 2 from moving due to accidental contact.

[0041] like Figure 3 As shown, further, the housing 1 is provided with a second accommodating groove 14 connected to the sliding groove 12 , and the sealing member 3 is placed in the second accommodating groove 14 .

[0042] In this embodiment, when it is necessary to inject the aerosol-generating medium into the liquid storage tank 10, the limiting portion 22 is pulled to disengage the limiting portion 22 from the first receiving groove 13. The limiting portion 22 drives the fixing portion 21 to slide in the sliding groove 12 in a direction away from the fixing groove 31, causing the fixing portion 21 to disengage the fixing groove 31 and thereby cancel the fixation of the sealing member 3. Then, the sealing member 3 is moved to disengage the sealing member 3 from the second receiving groove 14 and cancel the seal on the liquid injection hole 11. After the injection is completed and the injection tool is pulled out, the sealing member 3 is moved to be placed in the second receiving groove 14 and seal the liquid injection hole 11. Then, the limiting portion 22 is pushed to drive the fixing portion 21 to move in the sliding groove 12 toward the fixing groove 31, causing the fixing portion 21 to be inserted into the fixing groove 31 until the side wall of the limiting portion 22 abuts against the groove wall of the first receiving groove 13, thereby securing the sealing member 3.

[0043] like Figure 2 、 6 As shown, the atomizer further includes a reset membrane 4 located in the liquid storage tank 10 and used for opening and closing the liquid injection hole 11, and a groove (not shown) is provided on the reset membrane 4.

[0044] In this embodiment, see Figure 9 , move the fixing part 2 and the sealing part 3 in sequence, after the injection hole 11 is exposed, the injection tool is inserted into the liquid storage tank 10 through the groove of the reset membrane 4. After the injection tool injects the aerosol generating medium into the liquid storage tank 10, the injection tool is pulled out, and the reset membrane 4 automatically restores the seal of the injection hole 11.

[0045] In this embodiment, the sealing member 3 and the reset membrane 4 provide double sealing for the liquid injection hole 11 . When the sealing member 3 cancels the sealing of the liquid injection hole 11 , the reset membrane 4 can prevent leakage of the aerosol generating medium.

[0046] In this embodiment, the notch may be in the shape of a "-" or a "+" and this application does not limit this.

[0048] Furthermore, the connecting plug 32 , the sealing plug 34 and a portion of the connecting piece 33 are placed in the second receiving groove 14 .

[0049] In this embodiment, when it is necessary to inject an aerosol generating medium into the liquid storage tank 10, the limiting portion 22 is pulled, and the limiting portion 22 disengages from the first accommodating groove 13. The limiting portion 22 drives the fixing portion 21 to slide in the slide groove 12 in a direction away from the fixing groove 31, so that the fixing portion 21 disengages from the fixing groove 31 to cancel the fixation of the sealing member 3; then, the connecting piece 33 is pulled away from one end of the connecting plug 32, and the connecting piece 33 drives the sealing plug 34 to move in a direction away from the injection hole 11, so that the sealing plug 34 and part of the connecting piece 33 disengage from the second accommodating groove 14, and the sealing of the injection hole 11 is canceled. After the injection is completed and the injection tool is pulled out, align the sealing plug 34 with the injection hole 11 and insert it into the injection hole 11, so that the sealing plug 34 and part of the connecting piece 33 are placed in the second accommodating groove 14; then, push the limiting part 22, and the limiting part 22 drives the fixing part 21 to move in the sliding groove 12 toward the fixing groove 31, so that the fixing part 21 is inserted into the fixing groove 31 until the side wall of the limiting part 22 abuts against the groove wall of the first accommodating groove 13, so as to fix the sealing member 3.

[0050] In this embodiment, the seal 3 includes a connecting plug 32, a sealing plug 34 and a connecting piece 33, which facilitates the user to remove the sealing plug 34 through the connecting piece 33.

[0052] In this embodiment, the atomizer is used in an aerosol generating device. When inhalation begins during use, external air enters the atomizing chamber 51 through the air inlet 15 and the through hole 61 in sequence, and the aerosol generating medium in the liquid storage tank 10 enters the atomizing core 5 through the liquid inlet hole 52. At the same time, the atomizing core 5 is powered on and heated, and the aerosol generating medium is atomized to generate aerosol. Finally, the aerosol and the external air are discharged outward through the air outlet 16.

[0053] In this embodiment, the liquid absorbing member 6 can absorb the aerosol generating medium leaked from the atomizing core 5, thereby preventing the aerosol generating medium from leaking out of the atomizer through the air inlet 15, thereby preventing a short circuit between the aerosol generating device and the atomizer.
