Referring to fig. 1, as shown in fig. 1, an embodiment of the present utility model provides a liquid leakage preventing electronic atomizer 10, which includes a housing 100, a top cover 200, a spacer 300, a hold-down member 400, a lifting lever 500, and an atomization assembly 600; the top cover 200 is detachably coupled to one end of the housing 100; the atomizing assembly 600 is disposed inside the housing 100; the separator 300 is movably sleeved outside the atomizing assembly 600; the pressing down piece 400 and the lifting lever 500 are movably arranged inside the outer shell 100; the first end of the hold-down 400 abuts the first end of the lifting lever 500; the second end of the lifting lever 500 abuts to an end of the spacer 300 remote from the top cover 200; the atomization assembly 600 is provided with a liquid inlet 610; when the top cover 200 is connected to the housing 100, the top cover 200 abuts against the second end of the pressing piece 400, and the lifting lever 500 drives the spacer 300 to be separated from the outer side of the liquid inlet 610; when the top cover 200 is detached from the housing 100, the second end of the pressing member 400 protrudes out of one end of the housing 100, and the spacer 300 is coupled to the outside of the liquid inlet 610.

In this embodiment, the housing 100 has a hollow cavity, and the spacer 300, the hold-down 400, the lifting lever 500, and the atomizing assembly 600 are all disposed inside the housing 100. The interior of the housing 100 may also be divided into a plurality of cavities, each of which may house a different component. The end of the housing 100 adjacent the cap 200 is provided with an aerosol substrate cavity for storing an aerosol substrate. And a filling port is formed in one end, close to the top cover 200, of the housing 100, and when the top cover 200 is disassembled, aerosol substrates can be filled into the aerosol substrate cavity through the filling port. The atomizing assembly 600 is disposed in the aerosol matrix chamber of the housing 100, and the atomizing assembly 600 may include a heat generating assembly and an atomizing tube assembly, the heat generating assembly being received in the atomizing tube assembly, and the liquid inlet 610 being formed in the atomizing tube assembly. Aerosol substrate in the aerosol substrate cavity may enter the heat generating component inside the atomizing component 600 via the liquid inlet 610 and be heated by the heat generating component to be atomized into aerosol. Since the housing 100 and the top cover 200 are further provided with aerosol outlets corresponding to the positions of the atomizing assembly 600, the aerosols can reach the positions where the user can use the aerosols through the aerosol outlets.

The spacer 300 is a member that fits over the atomizing assembly 600 and is primarily used to isolate the atomizing assembly 600 from the aerosol substrate in the aerosol substrate chamber. When the top cover 200 is detached, the spacer 300 is in an isolated state, and is sleeved on the portion of the atomization assembly 600 where the liquid inlet 610 is formed, so as to shield and seal the liquid inlet 610, and at this time, aerosol substrates cannot enter the atomization assembly 600. The hold down 400 and the lifting lever 500 may also be correspondingly disposed in the aerosol matrix chamber, with the hold down 400 being located on the side of the lifting lever 500 that is adjacent to the cap 200. The lifting lever 500 is provided in a movable structure in which a first end of the lifting lever 500 is an end far from the spacer 300 and a second end of the lifting lever 500 is an end near to the spacer 300; the first end of the lower pressing piece 400 is an end near the lifting lever 500, and the second end of the lower pressing piece 400 is an end near the top cover 200.

The hold down 400 may be provided as a rod-like structure having a certain length. The lifting lever 500 is a lever structure rotatably provided inside the housing 100, and the second end thereof is lifted up when the first end thereof is depressed. Further, referring to fig. 2, when the top cover 200 is connected to the housing 100, the top cover 200 presses the pressing member 400, so as to drive the first end of the pressing member 400 to move away from the top cover 200, that is, to move toward the first end of the lifting lever 500, and the pressing member 400 presses the first end of the lifting lever 500 downward to lift the second end of the lifting lever 500. Because the second end of the lifting lever 500 abuts against the end of the spacer 300 away from the top cover 200, when the second end of the lifting lever 500 is lifted, the spacer 300 is lifted up, so that the spacer 300 moves towards the direction close to the top cover 200 and exposes the liquid inlet 610 in the atomizing assembly 600, and aerosol substrates can smoothly enter the atomizing assembly 600 and be atomized.

Referring to fig. 3, when the top cover 200 is detached, the second end of the lifting lever 500 is pressed down and returned to the isolated state due to the gravity of the spacer 300 itself; referring to fig. 4, the first end of the lifting lever 500 is lifted and the pushing member 400 is driven to lift, so that the second end of the pushing member 400 protrudes from the end of the housing 100 near the top cover 200. Furthermore, by providing the hold-down 400 and the lifting lever 500, the aerosol substrate can be isolated from the atomizing assembly 600 when the cap 200 is detached, so that the aerosol substrate filling operation can be smoothly performed, and the aerosol substrate can be prevented from leaking through the atomizing assembly 600 during the filling process.

In one embodiment, referring to fig. 5, the lifting lever 500 includes a lever body 510 and a lever shaft 520; the first end of the lever body 510 is abutted to the first end of the pressing piece 400, and the second end of the lever body 510 is abutted to the end of the spacer 300 away from the top cover 200; the lever shaft 520 is inserted between the first end and the second end of the lever body 510 and is movably connected to the inside of the housing 100; the lever body 510 is rotatably movable about the lever shaft 520.

In this embodiment, the lifting lever 500 includes a lever body 510 and a lever shaft 520. The first and second ends of the lever body 510 correspond to the first and second ends of the lifting lever 500, respectively. The lever shaft 520 is penetrated at a middle position of the lever body 510, that is, a position between the first end and the second end of the lever body 510. The lever shaft 520 is movably coupled to the inside of the housing 100, and the lever body 510 is rotatable around the lever shaft 520. Specifically, the lifting lever 500 is disposed on a plane in the interior of the housing 100, and when the first end of the lever body 510 is pushed down, it abuts on the plane, preventing further pushing down; similarly, when the second end of the lever body 510 is pushed down by the spacer 300, it will also abut against the plane, preventing further pushing down. Further, the lifting lever 500 can be rotated within a limited range.

In one embodiment, referring to fig. 2 or 3, the anti-leakage electronic atomizer 10 further includes a first spring 700; the first spring 700 is fixedly provided in the housing 100, and is provided at a side of the first end of the lifting lever 500 remote from the pressing piece 400.

In the present embodiment, the first spring 700 is disposed at a side of the first end of the lifting lever 500 away from the pressing member 400, and is abutted to the first spring 700 when the first end of the lifting lever 500 is pressed down. During the continuous pressing down, the compression amount of the first spring 700 gradually increases and a certain elastic potential energy is accumulated. When the first end of the lifting lever 500 is no longer pressurized, the elastic potential energy of the first spring 700 will be released, so as to accelerate the lifting of the first end of the lifting lever 500, so that the pressing speed of the second end of the lifting lever 500 is increased, and the spacer 300 is further made to rapidly close the liquid inlet 610, thereby realizing rapid switching of the closed state and further preventing leakage of aerosol matrix.

In an embodiment, referring to fig. 5, a first end of the lifting lever 500 is provided with a limiting latch 530; the limiting latch 530 faces the first spring 700; the outer diameter of the limit latch 530 is adapted to the inner diameter of the first spring 700; when the lifting lever 500 drives the spacer 300 to separate from the outside of the liquid inlet 610, the limiting latch 530 is clamped into the first spring 700.

In the present embodiment, the first end of the lifting lever 500 is provided with a limiting latch 530, and the limiting latch 530 is provided in the first end of the lifting lever 500 toward the direction of the first spring 700. Since the first spring 700 has an inner ring, the inner diameter of the inner ring is adapted to the outer diameter of the limiting latch 530, and the limiting latch 530 can be engaged into the inner ring of the first spring 700. When the first end of the lifting lever 500 is pressed down, that is, when the second end of the lifting lever 500 lifts the spacer 300, the limiting latch 530 penetrates the first spring 700, thereby preventing the lifting lever 500 from slipping or shifting in direction when contacting the first spring 700. After the limiting latch 530 is provided, when the pressing member 400 presses down the lifting lever 500, the lifting lever 500 will not deviate, so that the pressing failure of the pressing member 400 to press down the lifting lever 500 is prevented.

In one embodiment, referring to fig. 2 or 3, the anti-leakage electronic atomizer 10 further includes a second spring 800; the second spring 800 is sleeved outside the atomizing assembly 600 and is positioned at one side of the spacer 300 close to the top cover 200; when the lifting lever 500 drives the spacer 300 to separate from the outside of the liquid inlet 610, the spacer 300 abuts against the second spring 800.

In this embodiment, the inner diameter of the second spring 800 is adapted to the outer diameter of the atomizing assembly 600, i.e. the second spring 800 may be sleeved on the atomizing assembly 600. One end of the second spring 800 abuts against an inner wall of the housing 100 near one end of the top cover 200. When the spacer 300 is lifted by the lifting lever 500 to expose the liquid inlet 610, one end of the spacer 300 adjacent to the top cover 200 abuts against the other end of the second spring 800 and applies continuous pressure to the second spring 800. During lifting of the spacer 300, the second spring 800 is subjected to continuous pressure, and when the lifting lever 500 stops lifting the spacer 300, the second spring 800 rapidly bounces the spacer 300 to the closed state, further ensuring that the aerosol substrate is rapidly isolated.

In one embodiment, referring to fig. 5, a limiting tube 410 is sleeved on the pressing member 400; the shell 100 is provided with a pressing opening 110; the outer diameter of the limiting tube 410 is larger than the inner diameter of the pressing port 110; when the top cover 200 is detached from the housing 100, the second end of the pressing member 400 protrudes from one end of the housing 100 from the pressing opening 110, and the stopper 410 abuts against one side of the pressing opening 110 near the inside of the housing 100.

In this embodiment, the lower pressing member 400 is sleeved with a limiting tube 410, and the outer diameter of the limiting tube 410 is set to be larger than the outer diameter of the lower pressing member 400. The stopper tube 410 is sleeved in the hold-down 400 at a position between the first end and the second end. Specifically, the stopper pipe 410 may be sleeved in the lower pressing member 400 at a position near the second end, but the second end of the lower pressing member 400 is not wrapped by the stopper pipe 410, and remains exposed. A pressing opening 110 is formed in the case 100 at an end near the top cover 200, and a second end of the pressing piece 400 protrudes from the pressing opening 110 when the top cover 200 is detached. The inner diameter of the pressing opening 110 is smaller than the outer diameter of the limiting tube 410, and when the second end of the pressing member 400 protrudes from the pressing opening 110, the limiting tube 410 abuts against the inner wall of the end, close to the top cover 200, of the housing 100, so that excessive protruding portions of the second end of the pressing member 400 from the housing 100 are prevented, the position stability of the pressing member 400 inside the housing 100 is ensured, and the position switching reliability of the spacer 300 is ensured.

In an embodiment, referring to fig. 6, a chute 210 is disposed at an end of the top cover 200 near the housing 100; when the top cover 200 is coupled to the housing 100, the second end of the hold down 400 snaps into the chute 210.

In the present embodiment, a chute 210 is provided in the top cover 200 at an end near the housing 100. The chute 210 may be a groove structure recessed from an end of the top cover 200 near the housing 100 toward an end of the top cover 200 remote from the housing 100. The interior space of the chute 210 may be configured to fit the second end of the hold-down 400 such that the second end of the hold-down 400 can be received into the chute 210. By providing the chute 210, the top cover 200 is positioned and mounted to the top of the housing 100 in a proper posture, and pressure is applied to the pressing member 400 at a certain position, so that the pressing member 400 can be smoothly and accurately pressed down.

In one embodiment, referring to fig. 6, when the top cover 200 is coupled to the housing 100, the top cover 200 is rotatably coupled to one end of the housing 100; the chute 210 is disposed in an arc shape, and a distance between the first end of the chute 210 and the housing 100 is smaller than a distance between the second end of the chute 210 and the housing 100.

In the present embodiment, the top cover 200 may be provided in a structure capable of rotating at one end of the housing 100. Specifically, a snap-fit strip may be provided in the top cover 200 adjacent to one end of the housing 100 around the top cover 200, and a recessed snap-fit groove may be provided in the housing 100 adjacent to one end of the top cover 200. When the top cover 200 is coupled to the housing 100, the snap bars can snap into the snap grooves, and the top cover 200 can be rotated at one end of the housing 100 in a clockwise or counterclockwise direction. The sliding groove 210 may be correspondingly provided in an arc shape, and the direction in which the arc is provided is the same as the direction in which the top cover 200 can rotate. The second end of the lower press 400 can be received into the slide groove 210 when the top cover 200 is mounted to the housing 100, and the second end of the lower press 400 can move inside the slide groove 210 as the slide groove 210 moves when the top cover 200 rotates. Meanwhile, the distance between the first end of the chute 210 and the housing 100 is smaller than the distance between the second end of the chute 210 and the housing 100, i.e., the chute 210 is actually provided with a slope structure. The ramp structure allows the length of the hold down 400 to be depressed when the second end of the hold down 400 is positioned at different locations in the chute 210. Alternatively, the first end of the chute 210 may be disposed in a clockwise direction (from the end of the top cover 200 remote from the housing 100, looking toward the end proximate to the housing 100) of the second end. At this time, specifically, when the user needs to perform normal aerosol use, the top cap 200 may be rotated counterclockwise so that the second end of the pressing member 400 is positioned at the first end of the chute 210, the length of the pressing member 400 pressed down is the maximum length, at this time, the pressing member 400 presses down the first end of the lifting lever 500, the spacer 300 is lifted, the aerosol substrate can be contacted with the atomizing assembly 600, and aerosol is generated; subsequently, when the user stops using, the top cap 200 may be rotated clockwise such that the second end of the pressing member 400 is positioned at the second end of the chute 210, the pressing member 400 stops receiving the pressing force, at this time, the pressing member 400 does not press the first end of the lifting lever 500, the spacer 300 returns to the closed state, the aerosol substrate cannot contact the atomizing assembly 600, and thus the aerosol generation is stopped. By providing the chute 210 with different distances between the two ends and the housing 100, the user can isolate the aerosol substrate without disassembling the top cover 200, thereby meeting different needs in daily use.

In an embodiment, referring to fig. 1, 2 and 3, an end of the spacer 300 away from the top cover 200 is provided with a supporting portion 310; the supporting part 310 is arranged around the outer wall of the spacer 300; one end of the abutting portion 310 away from the top cover 200 abuts against the second end of the lifting lever 500.

In the present embodiment, the abutment 310 is a protruding structure surrounding the outer wall of the spacer 300. One end of the abutting portion 310 far away from the top cover 200 can be abutted by the second end of the lifting lever 500, and when the second end of the lifting lever 500 is lifted, the abutting portion 310 is actually lifted, so as to drive the isolation portion to lift. By providing the abutment 310, the stability and reliability of the operation of the lifting lever 500 is improved.

The outer diameter of the seal housing 900 may be configured to fit the inner diameter of the housing 100 such that the outer sidewall of the seal housing 900 can be snugly fitted against the inner sidewall of the housing 100. The seal seat 900 may be disposed in the aerosol substrate cavity at a location remote from the cap 200. The seal slot 910 may be configured as a groove structure that is adapted to the outer diameter of the atomizing assembly 600, and thus, the atomizing assembly 600 may be installed into the seal slot 910, enabling a more stable installation in the housing 100. Meanwhile, the inner diameter of the sealing groove 910 may be sized to fit the end of the spacer 300 remote from the top cap 200, so that the end of the spacer 300 remote from the top cap 200 can be inserted into the sealing groove 910 and more stable separation of the aerosol substrate is achieved.
