When the child lock mechanism is locked, the locking foot of the pressing part is stuck in the slot of the housing. At this time, the nozzle cover and the upper cover cannot be wound around. The axis of the housing rotates, so the oil filling hole cannot be opened. When it is necessary to fill the oil tank with oil, press the pressing part and the return spring deforms. At this time, the locking foot is free from the restriction of the slot, and the locking foot can rotate along the first guide groove. Because the child lock mechanism is fixed to the upper cover, the child lock mechanism is fixed to the upper cover. The lock mechanism rotates synchronously with the upper cover, and finally the upper cover rotates to open the oil filling hole, and the oil tank can be filled with oil. It can be seen that, in the present invention, the child lock mechanism corresponding to the oil injection hole has a simple structure and is convenient to operate. It can effectively realize the child lock function and prevent children from opening the oil injection hole and touch the e-liquid, and the user experience is good.

As another preferred manner, the elastic mechanism includes a connecting rod and a supporting rod, one end of the pressing part is connected to one end of the supporting rod through the connecting rod, the locking foot is provided at the other end of the pressing part, and the other end of the supporting rod is connected to the upper The cover is connected, the pressing part, the connecting rod and the supporting rod form a gap; the side of the pressing part passes through the side wall of the nozzle cover and is exposed. That is, in the second invention solution, the atomizer includes a shell, an oil tank is arranged in the shell, and an oil injection hole is provided on the shell for filling oil into the oil tank. The end of the shell and the upper part of the oil injection hole can be opened or closed. The cover is connected, the upper cover is fixedly connected with the nozzle cover, and it also includes a child lock mechanism that cooperates with the opening of the oil filling hole. The structural feature is that the child lock mechanism includes a pressing part, a connecting rod, and a supporting rod. One end of the pressing part passes through the connecting rod. Connected to one end of the support rod, the other end of the pressing part has a locking foot, the other end of the support rod is connected to the upper cover, and a gap is enclosed between the pressing part, the connecting rod and the support rod; the side of the pressing part passes through the side wall of the nozzle cover and is exposed ; The top of the housing has a first guide groove and a locking groove that is matched with the locking foot. The first guide groove communicates with the locking groove and acts as a nozzle cover, an upper cover, and a child lock mechanism synchronously rotating around the housing axis when the lock Guide groove for tight feet.

With the above structure, under normal conditions, the upper cover closes the oil filling hole of the shell. When the child lock mechanism is locked, the locking feet of the child lock mechanism are stuck in the slot of the shell. At this time, the nozzle cover and the upper cover cannot It rotates around the axis of the housing, so the oil filling hole cannot be opened. When the oil tank needs to be filled with oil, the hand presses the pressing part, and the pressing part deforms and moves into the gap after being pressed. At this time, the locking foot is out of the restriction of the groove, and the locking foot can rotate along the first guide groove. The child lock mechanism is fixed to the upper cover, so the child lock mechanism rotates synchronously with the upper cover, and finally the upper cover rotates to open the oil filling hole, and oil can be filled into the oil tank. It can be seen that, in the present invention, the child lock mechanism corresponding to the oil injection hole has a simple structure and is convenient to operate. It can effectively realize the child lock function and prevent children from opening the oil injection hole and touch the e-liquid, and the user experience is good.

Further, the bottom of the upper cover has a convex point, the top of the housing also has a second guide groove, the second guide groove is located outside the first guide groove, the second guide groove communicates with the card groove and serves as a nozzle cover, upper cover, and child lock mechanism The guide groove of the convex point when synchronously rotating around the axis of the casing; the length of the locking foot is greater than the length of the convex point, and the bottom surface of the first guide groove is lower than the bottom surface of the second guide groove.

With the above structure, during the process of rotating the upper cover to open the oil injection hole, the convex point enters the second guide groove and rotates along the second guide groove. Because the length of the locking foot and the convex point are different, the depth of the first guide groove and the second guide groove are different, the first guide groove and the second guide groove are staggered, so when the nozzle cover is turned after unlocking, the locking foot and The convex point rotates independently in the corresponding guide groove, and the motion trajectories of the two will not interfere with each other.

Further, the top of the housing is provided with a limiting step corresponding to the convex point for limiting the rotation direction of the upper cover.

With the above structure, the limit step can limit the one-way rotation of the upper cover (for example, it can only rotate counterclockwise). Because the locking mechanism and the nozzle cover and the upper cover are connected as a whole and rotate synchronously, they can only be rotated in one direction. . When the upper cover rotates 90° counterclockwise, the convex point just abuts on the slot, so the slot restricts the rotation of the upper cover, restricting the upper cover to only rotate 90° counterclockwise. If the limit step is not set, 360° rotation can also be realized.

Further, the top of the housing is further provided with a convex bone adjacent to the limiting step, and the convex point has a groove corresponding to the convex bone.

At this time, the upper cover can be rotated to open the oil filling hole and the oil can be filled. When the force is more uniform, the movement state is more stable.

Further, it also includes an atomizing core, the atomizing core includes an oil inlet, an oil guiding mechanism, and an atomizing member. The housing is also provided with a containing cavity. The atomizing core is arranged in the containing cavity, and the oil tank passes through the oil hole in turn , The oil inlet, the oil guide mechanism and the atomizer are connected.

The e-liquid in the oil silo passes through the oil hole and the oil inlet in turn to reach the oil guide mechanism, and then the oil guide mechanism causes the atomizing part to atomize and produce smoke for the user to inhale.

In the normal state, the upper cover 3 closes the oil injection hole 101 of the housing 1. In the locked state of the child lock mechanism 5, the locking foot 5021 of the pressing portion 502 is stuck in the slot 103 of the housing 1. At this time, the nozzle cover 4 and The upper cover 3 cannot rotate around the axis of the housing 1, so the oil filling hole 101 cannot be opened. When the oil tank 2 needs to be filled with oil, press the pressing portion 502, and the return spring 501 is deformed. At this time, the locking foot 5021 is free from the restriction of the groove 103, and the locking foot 5021 can rotate along the first guide groove 102 due to the child lock mechanism 5 is fixed to the upper cover 3, so the child lock mechanism 5 rotates synchronously with the upper cover 3, and finally the upper cover 3 rotates to open the oil filling hole 101, and the oil tank 2 can be filled with oil.

The suction nozzle cover 4 is provided with an air inlet 401 and an air outlet 402. An air passage 16 is formed between the air pipe 15 and the inner sleeve 609. The gas enters from the air inlet 401, passes through the air pipe 15 and reaches the bottom of the cup-shaped oil-conducting cotton. , The smoke generated by the atomization of the ultrasonic atomizing sheet is brought out through the air outlet 16 and the air outlet 402 in order for the user to inhale. The direction of airflow is shown by the arrows in Figure 1 and Figure 2.

13 to 15 show the working principle of the child lock mechanism 5 of the oil filling hole 101 of the atomizer of the present invention.

As shown in FIG. 13, when the pressing portion 502 of the child lock mechanism 5 is not pressed, the locking leg 5021 of the pressing portion 502 is stuck in the slot 103 of the housing 1, and the slot 103 restricts the locking leg 5021. The pressing part 502 and the upper cover 3 are rotated so that the oil injection hole 101 cannot be opened, and the oil injection hole 101 is in a closed state. At this time, the oil passage 701 communicates with the oil inlet 6011 through the passage groove 6031, and the oil path is connected. The e-liquid in the oil tank 2 can be led to the cup-shaped oil-conducting cotton, and then lead to the atomization of the ultrasonic atomizing sheet The surface is atomized to produce smoke.

As shown in Figure 14, when the oil tank 2 needs to be filled with oil, the two pressing parts 502 are pressed at the same time, and the return spring 501 is deformed. At this time, the locking foot 5021 is out of the restriction of the slot 103, and the locking foot 5021 can move along the first The guide groove 102 rotates, and the bump 302 enters the second guide groove 104 and can rotate along the second guide groove 104.

As shown in FIG. 15, because the child lock mechanism 5 is fixed to the upper cover 3, the child lock mechanism 5 rotates synchronously with the upper cover 3, and the upper cover 3 can only rotate counterclockwise due to the setting of the limit step 105. When the upper cover 3 rotates 90° counterclockwise, the bump 302 just abuts on the slot 103, so the slot 103 limits the rotation of the upper cover 3, restricting the upper cover 3 to rotate 90° counterclockwise. The oil filling hole 101 is in an open state, and oil can be filled into the oil tank 2. At the same time, because the atomization sleeve 7 is integrated with the upper cover 3 through the connecting piece 8, the atomization sleeve 7 also rotates 90° counterclockwise synchronously. At this time, the oil passage 701 is misaligned with the oil inlet 6011, and the oil circuit is shut off. The e-liquid in the warehouse 2 cannot be led to the cup-shaped oil-conducting cotton, which can prevent oil leakage.

Example two

As shown in Figures 16 to 24, the atomizer in the electronic cigarette of the present invention includes a housing 1, an oil tank 2 is provided in the housing 1, and an oil injection hole 101 for filling oil into the oil tank 2 is also provided on the housing 1. The end is connected to the upper cover 3 that can open or close the oil injection hole 101, and the upper cover 3 is fixedly connected to the nozzle cover 4, and further includes a child lock mechanism 5 that cooperates with opening the oil injection hole 101. The child lock mechanism 5 includes The pressing part 502, the connecting rod 504, and the supporting rod 505, one end of the pressing part 502 is connected to one end of the supporting rod 505 through the connecting rod 504, the other end of the pressing part 502 has a locking foot 5021, and the other end of the supporting rod 505 is connected to the upper cover 3 to press A gap 506 is enclosed between the connecting rod 504 and the supporting rod 505; the side of the pressing part 502 passes through the side wall of the nozzle cover 4 and is exposed; the upper cover 3 has a mounting groove 301 opposite to the locking foot 5021; the housing 1 The top has a first guide groove 102 and a card slot 103 matched with the locking foot 5021. The first guide groove 102 communicates with the card slot 103 and serves as the nozzle cover 4, the upper cover 3, and the child lock mechanism 5 synchronously around the axis of the housing 1 The guide groove of the locking foot 5021 when rotating in the circumferential direction.

Under normal conditions, the upper cover 3 closes the oil injection hole 101 of the housing 1. When the child lock mechanism 5 is locked, the locking foot 5021 of the child lock mechanism 5 is stuck in the slot 103 of the housing 1, and the nozzle cover 4 And the upper cover 3 cannot rotate around the axis of the housing 1, so the oil filling hole 101 cannot be opened. When the oil tank 2 needs to be filled with oil, the hand presses the pressing part 502. The pressing part 502 is deformed and moved into the gap 506 after being pressed. At this time, the locking foot 5021 is out of the restriction of the slot 103, and the locking foot 5021 can move along The first guide groove 102 rotates. Since the child lock mechanism 5 is fixed to the upper cover 3, the child lock mechanism 5 rotates synchronously with the upper cover 3, and finally the upper cover 3 rotates to open the oil filling hole 101, and the oil tank 2 can be filled with oil. It can be seen that, in the present invention, the child lock mechanism 5 corresponding to the oil injection hole 101 has a simple structure and is easy to operate, which can effectively realize the child lock function and prevent children from opening the oil injection hole 101 and contact the smoke oil, and the user experience is good.

The limit step 105 can restrict the upper cover 3 from rotating in one direction (for example, it can only rotate counterclockwise). Since the locking mechanism and the nozzle cover are connected to the upper cover 3 as a whole and rotate synchronously, they can only rotate in one direction. If the limit step 105 is not provided, 360° rotation can also be realized.

The top of the housing 1 is also provided with a protrusion 107 adjacent to the limiting step 105, and the protrusion 302 has a groove 3021 corresponding to the protrusion 107. In the initial state, the protruding bone 107 is aligned with the groove 3021, which further restricts the upper cover 3 from being easily rotated in the initial state; at the same time, it can also act as a reminder that the upper cover 3 is locked in place, and the user experience is good .

The child lock mechanism 5 and the upper cover 3 are integrally formed. The locking mechanism 5 and the upper cover 3 are integrally formed, so that the production of the upper cover 3 can be completed by a set of molds, and the locking mechanism 5 has good elastic restoring force, durability, simple structure and low cost.

The child lock mechanism 5 is provided with two sets, and the two child lock mechanisms 5 are symmetrically arranged on two opposite sides of the nozzle cover 4. Two sets of child lock mechanisms 5 are provided. When the two pressing parts 502 are pressed down at the same time, the child lock mechanism 5 can be unlocked. At this time, the upper cover 3 can be rotated to open the oil filling hole 101 to fill oil, which further increases the working reliability of the child lock mechanism 5. When the upper cover 3 is rotated at the same time, the force is more uniform and the movement state is more stable.

The bottom of the housing 1 is provided with a bottom cover 10, a second through hole 1001 is opened at the center of the bottom cover 10, and the upper part of the atomizing core 6 passes through the second through hole 1001 and the first through hole 901 in turn and extends into the atomizing sleeve 7 In the inner cavity, the bottom of the atomization core 6 is fixed in the second through hole 1001; the bottom cover 10 is provided with a clasp for taking the atomization core 6 out of the containing cavity 106. The buckle part for pulling out the atomization core 6 is provided to facilitate the replacement of the atomization core 6.

The suction nozzle cover 4 is provided with an air inlet 401 and an air outlet 402. An air passage 16 is formed between the air pipe 15 and the inner sleeve 609. The gas enters from the air inlet 401, passes through the air pipe 15 and reaches the bottom of the cup-shaped oil-conducting cotton. , The smoke generated by the atomization of the ultrasonic atomizing sheet is brought out through the air outlet 16 and the air outlet 402 in order for the user to inhale. The direction of airflow is shown by the arrow in Figure 16.

Figures 25-27 show the working principle of the child lock mechanism 5 of the oil injection hole 101 of the atomizer of the present invention.

As shown in FIG. 25, when the pressing portion 502 of the child lock mechanism 5 is not pressed, the locking leg 5021 of the child lock mechanism 5 is stuck in the slot 103 of the housing 1, and the slot 103 restricts the locking leg 5021. At the same time, the protruding rib 107 is aligned with the groove 3021, and the nozzle cover 4 and the upper cover 3 cannot be rotated, so the oil injection hole 101 cannot be opened, and the oil injection hole 101 is in a closed state. At this time, the oil passage 701 communicates with the oil inlet 6011 through the passage groove 6031, and the oil path is connected. The e-liquid in the oil silo 2 can be led to the cup-shaped oil-conducting cotton, and then lead to the atomization of the ultrasonic atomizing sheet The surface is atomized to produce smoke.

As shown in Figure 26, when the oil tank 2 needs to be filled with oil, press the pressing parts 502 of the two locking mechanisms 5 at the same time. The pressing parts 502 deform and move into the gap 506 after being pressed. At this time, the locking feet 5021 are disengaged Due to the restriction of the card slot 103, the locking foot 5021 can rotate along the first guide slot 102, and the convex point 302 can enter the second guide slot 104 and can rotate along the second guide slot 104.

As shown in Fig. 27, since the child lock mechanism 5 and the upper cover 3 are integrally formed, the child lock mechanism 5 rotates synchronously with the upper cover 3. Due to the setting of the limit step 105, the upper cover 3 can only rotate counterclockwise. When the upper cover 3 rotates 90° counterclockwise, the bump 302 just abuts on the slot 103, so the slot 103 limits the rotation of the upper cover 3, restricting the upper cover 3 to rotate 90° counterclockwise. The oil filling hole 101 is in an open state, and oil can be filled into the oil tank 2. At the same time, because the atomization sleeve 7 is integrated with the upper cover 3 through the connecting piece 8, the atomization sleeve 7 also rotates 90° counterclockwise synchronously. At this time, the oil passage 701 is misaligned with the oil inlet 6011, and the oil circuit is shut off. The e-liquid in the warehouse 2 cannot be led to the cup-shaped oil-conducting cotton, which can prevent oil leakage.
