When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] The specific structure of the atomizing device will be mainly described below.

[0034] Reference Figures 1 to 4 In an embodiment of the present invention, the atomizing device is used to be combined with the power supply device to form an atomizing device, and the atomizing device includes:

[0035] The main body 100 is formed with an oil injection cavity 110 and an oil storage cavity 120. The cavity wall of the oil injection cavity 110 is provided with a movable hole and an oil injection hole. The movable hole extends to the outside of the atomizing device, and the oil injection hole extends to communicate with the oil storage cavity 120.

[0036] A movable sealing rod 200 is movably arranged in the movable hole and the oil injection hole. The movable sealing rod 200 includes a sealing section 210 and an oil passing section 220. The outer diameter of the sealing section 210 is larger than the outer diameter of the oil passing section 220, and the outer diameter of the oil passing section 220 is smaller than the inner diameter of the oil injection hole, so that the movable sealing rod 200 has an oil blocking position and an oil passing position on the movable track;

[0037] When in the oil blocking position, the sealing section 210 is inserted into the movable hole and the oil injection hole in sequence to block the movable hole and the oil injection hole;

[0038] When in the oil passing position, the oil passing section 220 is penetrated by the oil filling hole, so that the tobacco oil in the oil filling chamber 110 can enter the oil storage chamber 120 through the flow gap 201 between the hole wall of the oil filling hole and the oil passing section 220 .

[0039] Specifically, in this embodiment, since the movable sealing rod 200 is movably arranged in the movable hole and the oil injection hole, and the movable hole extends to the outside of the atomizing device, the user can operate the movable sealing rod 200, and the size of the sealing section 210 of the movable sealing rod 200 matches the size of the movable hole and the oil injection hole, so that when the movable sealing rod 200 moves to the oil blocking position, different positions of the sealing section 210 can block the movable hole and the oil injection hole respectively. It is worth mentioning that the sizes of the movable hole and the oil injection hole can be the same or different, and there is no strict restriction here, as long as it is ensured that when the movable sealing rod 200 moves to the oil blocking position, different positions of the sealing section 210 can block the movable hole and the oil injection hole respectively.

[0040] Before the atomizer is used, the oil storage chamber 120 is not filled with tobacco oil, tobacco oil is injected into the oil filling chamber 110, and the movable sealing rod 200 is operated to the oil blocking position, so that the sealing section 210 of the movable sealing rod 200 blocks the movable hole and the oil filling hole, so that the tobacco oil in the oil filling chamber 110 does not flow into the oil storage chamber 120. In this way, before the atomizer is used, there is no tobacco oil in the oil storage chamber 120, and the atomizer core in the atomizing chamber 130 is not adsorbed with tobacco oil. The tobacco oil is located in the sealed oil filling chamber 110, so it is not easily oxidized by air.

[0041] When the user needs to use the atomizer, the movable sealing rod 200 is operated to be located at the oil passing position, so that the tobacco oil in the oil filling chamber 110 can enter the oil storage chamber 120 through the flow gap 201 between the hole wall of the oil filling hole and the oil passing section 220, and the tobacco oil in the oil storage chamber 120 then flows and is adsorbed to the atomization core in the atomization chamber 130, so as to be subsequently atomized into aerosol for the user to inhale.

[0042] The technical solution of the present invention is provided with a movable sealing rod 200 including a sealing section 210 and an oil passing section 220, so that whether the oil filling chamber 110 is connected to the oil storage chamber 120 can be controlled by operating the movable sealing rod 200. In this way, before using the atomizer, the smoke oil can be injected into the oil filling chamber 110, and the movable sealing rod 200 is operated to block the oil filling hole to seal the oil filling chamber 110, so that the smoke oil in the oil filling chamber 110 is not easily oxidized by air, thereby ensuring the quality of the smoke oil, thereby ensuring the taste of the smoke oil after being atomized into aerosol, and improving the user experience. When the atomizer needs to be used, the smoke oil can enter the oil storage chamber 120 through the flow gap 201 between the hole wall of the oil filling hole and the oil passing section 220 by operating the movable sealing rod 200, and the smoke oil in the oil storage chamber 120 flows and is adsorbed to the atomizer core in the atomizer chamber 130, so as to be atomized into aerosol for the user to inhale, and the operation is simple and convenient.

[0043] In actual application, the length of the sealing section 210 of the movable sealing rod 200 can be controlled so that when the movable sealing rod 200 is in the oil passing position, the sealing section is still partially inserted into the movable hole, so that the oil filling chamber is still relatively sealed during oil filling.

[0044] To improve the sealing performance of the oil injection cavity 110, in some embodiments, the outer wall of the sealing section 210 is sleeved with a first sealing ring 510 and a second sealing ring 520. When the movable sealing rod 200 is located at the oil blocking position, the first sealing ring 510 abuts against the inner wall of the movable hole, and the second sealing ring 520 abuts against the inner wall of the oil injection hole. Both the first sealing ring 510 and the second sealing ring 520 can play a sealing role to ensure the sealing performance of the oil injection cavity 110. Furthermore, the outer wall of the sealing section 210 is spaced apart with a first limiting groove 211 and a second limiting groove 212 both extending circumferentially along the sealing section 210. The first sealing ring 510 is sleeved in the first limiting groove 211, and the second sealing ring 520 is sleeved in the second limiting groove 212. The first limiting groove 211 limits the first sealing ring 510, and the second limiting groove 212 limits the second sealing ring 520, thereby ensuring the stability of the first sealing ring 510 and the second sealing ring 520, so as to stably and reliably perform the sealing function.

[0045] In some embodiments, the movable sealing rod 200 also includes a limiting section 230, which is connected to one end of the oil passage section 220 away from the sealing section 210, the limiting section 230 is located in the oil storage chamber 120, and the diameter of the limiting section 230 is greater than the inner diameter of the oil filling hole; the atomization device also includes an elastic return member 300, which is located between the outer wall of the oil filling hole and the limiting section 230, and is sleeved on the oil passage section 220, the elastic return member 300 has a natural extension state and a compression state, in the natural extension state, one end of the elastic return member 300 is in contact with or fixedly connected to the limiting section 230, and the other end is close to or in contact with the outer wall of the oil filling hole, and the movable sealing rod 200 is located in the oil blocking position; in the compression state, the elastic return member 300 is compressed between the limiting section 230 and the outer wall of the oil filling hole, and the movable sealing rod 200 is located in the oil passing position. In this way, by reasonably designing the length of the elastic reset member 300, the elastic reset member 300 can be in a naturally extended state and the movable sealing rod 200 can be in an oil blocking position; when it is necessary to add tobacco oil to the oil storage chamber 120, the movable sealing rod 200 is pulled outside the atomization device so that the movable sealing rod 200 is in an oil passing position, so that the tobacco oil can enter the oil storage chamber 120 through the flow gap 201 between the hole wall of the oil filling hole and the oil passing section 220, thereby completing the oil filling; after the oil filling is completed, the movable sealing rod 200 is released again, the elastic reset member 300 is reset, and the naturally extended state is restored, and the movable sealing rod 200 returns to the oil blocking position.

[0046] Furthermore, in some embodiments, by reasonably controlling the length of the limit section 230, when the elastic return member 300 is naturally extended, the end of the limit section 230 away from the oil passing section 220 abuts against the wall of the oil storage chamber 120. In this way, the movable sealing rod 200 is restricted by the oil storage chamber 120 and will not excessively extend into the oil storage chamber 120, thereby ensuring that the user can operate the movable sealing rod 200 normally.

[0047] In some embodiments, the atomizing device further comprises a lifting member 400, the diameter of which is greater than the inner diameter of the movable hole, the lifting member 400 is located outside the main body 100 and is installed at one end of the sealing section 210 away from the oil passing section 220, the elastic reset member 300 is in the naturally extended state, the lifting member 400 abuts against the outer wall of the movable hole, and the elastic reset member 300 is in the compressed state, the lifting member 400 is away from the movable hole. The user can operate the movable sealing rod 200 by operating the lifting member 400, and since the lifting member 400 is located outside the main body 100, the user can operate conveniently, and it also plays a limiting role to prevent the movable sealing rod 200 from excessively extending into the oil storage chamber 120.

[0048] In some embodiments, the cavity wall of the oil storage cavity 120 is provided with a limiting convex ring 123, the limiting convex ring 123 is located outside the oil filling hole and is arranged around the oil passing section 220 of the movable sealing rod 200, and the elastic reset member 300 is partially located in the limiting convex ring 123; the limiting section 230 of the movable sealing rod 200 is provided with an oil passing notch 231, and the oil passing notch 231 runs from the side of the limiting section 230 close to the sealing section 210 to the side away from the sealing section 210. When the movable sealing rod 200 is located at the oil passing position, the side of the limiting section 230 close to the sealing section 210 abuts against the end wall of the limiting convex ring 123, and the oil passing notch 231 is connected with the oil storage cavity 120. In this way, after the smoke oil passes through the oil filling hole, it can enter the oil storage cavity 120 through the inside of the limiting convex ring 123 and the oil passing notch 231 in sequence to ensure normal oil filling. The setting of the limiting convex ring 123 can limit the elastic reset member 300, prevent the elastic reset member 300 from being skewed or offset, and ensure the use effect of the elastic reset member 300; at the same time, it can also limit the movable sealing rod 200, prevent the movable sealing rod 200 from excessively extending out of the atomization device, and ensure the use effect of the movable sealing rod 200.

[0049] Furthermore, a limiting protrusion 221 is convexly provided on the outer circumference of the oil passing section 220, and the limiting protrusion 221 extends along the circumference of the oil passing section 220. The elastic reset member 300 is sleeved on the limiting protrusion 221. The limiting protrusion 221 is provided with a connecting notch 222 at a position corresponding to the oil passing notch 231, and the connecting notch 222 runs through the side of the limiting protrusion 221 close to the sealing section 210 and the side away from the sealing section 210. The limiting protrusion 221 can limit the end of the elastic reset member 300 away from the oil filling hole, further ensuring the use effect of the elastic reset member 300.

[0050] In some embodiments, the cavity wall of the oil injection cavity 110 is formed with an opening protrusion 111, and the movable hole is opened in the opening protrusion 111. In this way, the length of the formed movable hole is ensured to be longer, so as to increase the contact area between the movable sealing rod 200 and the movable hole, avoid the movable sealing rod 200 from deviating, and ensure the use effect of the movable sealing rod 200.

[0051] In some embodiments, the oil storage chamber 120 includes a storage chamber 121 and a transfer chamber 122 arranged adjacent to each other. The storage chamber 121 is used to communicate with the atomization chamber 130 of the atomization device. An oil storage cotton 124 is installed in the storage chamber 121. The cavity wall of the storage chamber 121 is provided with a connecting hole extending to communicate with the transfer chamber 122. The transfer chamber 122 is connected with the oil injection hole. The volume of the transfer chamber 122 is smaller than the volume of the oil injection chamber 110. The transfer chamber 122 plays the role of adding the tobacco oil in the oil injection chamber 110 to the storage chamber 121 in small amounts and multiple times, so that most of the tobacco oil is located in the sealed oil injection chamber 110, and is added to the storage chamber 121 when it is needed, shortening the time for the tobacco oil to contact with the air before atomization, thereby reducing the time for the tobacco oil to volatilize and be oxidized by the air, thereby improving the taste of the tobacco oil after being atomized into aerosol, and enhancing the user experience.

[0052] Furthermore, the storage chamber 121 and the transfer chamber 122 are arranged on the left and right, the oil filling chamber 110 is located above the storage chamber 121 and the transfer chamber 122, the movable hole is arranged at the upper end of the oil filling chamber 110, the oil filling hole is arranged at the lower end of the oil filling chamber 110, and the connecting hole is connected to the bottom of the transfer chamber 122. The directional indication described in this embodiment is used to explain the relative position relationship between the various parts of the atomizer when the atomizer is in use. In this embodiment, the movable hole is located at the upper end of the oil filling chamber 110, so that when the atomizer is in use, the smoke oil will not enter the movable hole, and will not flow out of the atomizer through the movable hole, further reducing the risk of oil leakage. The connecting hole is located at the bottom of the transfer chamber 122, which is convenient for the smoke oil to flow into the storage chamber 121 after being injected into the transfer chamber 122, thereby improving the oil filling efficiency.

Since the atomizing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0054] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
