Abstract
Description
Technical Field
[0001] The utility model relates to the field of electronic cigarettes, in particular to a liquid leakage-proof atomizer. Background Art
[0002] E-cigarettes are electronic products that mimic cigarettes. Their working principle is that the atomizer heats and atomizes the e-liquid, generating smoke. The user's suction action generates airflow that carries the smoke into the mouth. Because an airway must be established in the atomizer for air flow, there is a chance that the e-liquid will leak out of the air inlet at the bottom or the air outlet at the top of the atomizer, which manifests as e-liquid leakage from the atomizer's mouthpiece (corresponding to the air outlet) or the air inlet (commonly seen at the connection between the cartridge and the cigarette holder).
[0003] Currently, the general solution to the atomizer leakage problem is to ensure that the e-cigarette is placed in an upright position when placed (or worn on the chest as a necklace), avoiding inversion or flatness. However, even in the upright position, because the oil guide body and the oil storage tank in the atomizer core are always in a conductive state, the oil seeping from the oil guide body will flow down the airway under the action of gravity, and finally the oil will seep out at the air inlet. Therefore, the current atomizer leakage problem still cannot be effectively solved. Utility Model Content
[0004] Based on this, the utility model provides a leakage-proof atomizer, in which a leakage-proof unit is arranged on the base of the atomizer core, which can effectively reduce the probability of smoke oil seeping from the air inlet, thereby alleviating the problem of atomizer leakage.

At this time, the plug is inserted into the air guide groove under the drive of the elastic member, thereby cutting off the conductive state between the air guide groove and the air inlet. When the user needs to smoke the electronic cigarette, the tail of the plug is pulled out to the outside of the base, and then the plug is rotated so that the tail of the plug is inserted into the second card slot of the cover plate. At this time, the plug exits the air guide groove, so that the air guide groove and the air inlet are restored to the conductive state. Through the above-mentioned design, the anti-leakage unit is provided on the base of the atomizer core, which can effectively reduce the probability of smoke oil leaking from the air inlet, thereby alleviating the problem of liquid leakage in the atomizer.

Figure 7 As shown, the plug 141 is arranged along the radial direction of the air guide groove 112, and the head of the plug 141 abuts against the inner wall of the air guide groove 112 to cut off the conduction state between the air guide groove 112 and the air inlet 113 (see Figure 7 and Figure 10 The elastic member 142 is sandwiched between the plug 141 and the cover plate 143, and the elastic member 142 is used to provide a driving force for the plug 141 to slide back. Figure 6 and Figure 7As shown, the cover plate 143 is provided with a clearance hole 1431 for the tail of the plug 141 to pass through. A first retaining groove 1432 and a second retaining groove 1433 are provided on the outside of the cover plate 143. The first retaining groove 1432 and the second retaining groove 1433 are arranged crosswise and are both used to position the tail of the plug 141. The depth of the first retaining groove 1432 is greater than the depth of the second retaining groove 1433. For example, in this embodiment, the difference in depth between the first retaining groove 1432 and the second retaining groove 1433 is approximately equal to the diameter of the air guide groove 112.
[0049] In order to facilitate user operation, in this embodiment, Figure 8 As shown, the tail of the plug 141 is T-shaped. Accordingly, the first slot 1432 and the second slot 1433 are both in a straight line and extend radially to both sides with the avoidance hole 1431 as the center. The T-shaped tail is easy for users to grasp and improves the convenience of operation.
[0050] In order to make the sealing effect of the plug 141 better and take into account the convenience of installation, Figure 7 and Figure 8 As shown, in this embodiment, the head of the plug 141 is an elastic bullet-shaped structure, the tail of the plug 141 is a rigid columnar structure.

When the cover plate 143 needs to be disassembled, the operation can be completed by rotating the screws 16, which is simple to operate and has good connection stability.
[0053] like Figure 3 As shown, the oil reservoir 20 is connected to the atomizer chamber to supply oil to the oil guide body 13. In this embodiment, the oil reservoir 20 is a cylindrical structure and is mounted on the outer periphery of the air pipe 30. The mouthpiece 40 is located at the top of the oil reservoir 20, the base 11 is located at the bottom of the oil reservoir 20, and the atomizer chamber 111 is located within the oil reservoir 20. In other embodiments, the oil reservoir 20 can also be located on the side of the atomizer core 10 and connected to the atomizer chamber 111 of the base 11 via a conduit or a built-in flow channel.
[0054] Furthermore, in order to facilitate user use, the oil storage bin 20 is preferably a transparent tube. The transparent oil storage bin 20 facilitates the user to intuitively know the remaining amount of tobacco oil in the oil storage bin 20.
[0055] like Figure 3 As shown, the air pipe 30 is connected to the top of the atomizing chamber 111. For example, in this embodiment, the air pipe 30 is a straight pipe, one end of which is connected to the base 11 and the other end is connected to the mouthpiece 40.

[0057] In addition, if Figure 3 and Figure 4 As shown, in this embodiment, the leak-proof atomizer 100 may further include a clamping member 60 detachably connected between the oil storage tank 20 and the mouthpiece 40. The clamping member 60 is sleeved on the top of the air pipe 30. When the oil storage tank 20 needs to be filled with oil, the clamping member 60 can be removed and then replaced after filling is completed.
[0058] Brief description of working principle:
[0059] like Figure 3 As shown, a leak-proof unit 14 is provided on the atomizer core 10 for preventing the smoke oil from leaking from the air inlet 113 .
[0060] like Figure 7 As shown, when the user does not need to smoke the electronic cigarette, the tail of the plug 141 is inserted into the first slot 1432 of the cover plate 143. At this time, the plug 141 is inserted into the air guide groove 112 under the drive of the elastic member 142, thereby cutting off the connection between the air guide groove 112 and the air inlet 113.
[0061] like Figure 10 As shown, when the user needs to smoke the electronic cigarette, the tail of the plug 141 is pulled outward from the base 11, and then the plug 141 is rotated so that the tail of the plug 141 is inserted into the second slot 1433 of the cover 143. At this time, the plug 141 withdraws from the air guide groove 112, so that the air guide groove 112 and the air inlet 113 are restored to the conductive state.
[0062] For example, Figure 7 For example, when the user does not need to smoke the electronic cigarette, the tail of the plug 141 is inserted into the first card slot 1432. Driven by the elastic member 142, the plug 141 pushes against the inner wall of the air guide groove 112, thereby cutting off the conduction state between the air guide groove 112 and the air inlet 113. Figure 9 and Figure 10As shown, when a user needs to smoke an electronic cigarette, they pull outward the T-shaped tail of the plug 141 that is inserted into the first slot 1432, rotate it 90 degrees, and then release the tail of the plug 141. Driven by the elastic member 142, the tail of the plug 141 is locked in the second slot 1433, and the plug 141 is withdrawn outward relative to the air guide groove 112, thereby restoring the conductive state between the air guide groove 112 and the air inlet 113. The user only needs to pull and rotate the tail of the plug 141 to switch the airway at the air inlet 113 between the conductive and closed states. This operation is very simple and can effectively reduce the risk of smoke liquid leakage from the air inlet 113.
[0063] In addition, in some embodiments, the head of the plug 141 can be provided with a detachable oil-absorbing cotton block (it is necessary to ensure that the oil-absorbing cotton block is set upward when blocking the air guide groove 112). Its function is to absorb most of the smoke oil leaked into the plug 141 through the oil-absorbing cotton block, and the detachable design of the cover 143 can, on the one hand, enhance the leak-proof performance, and on the other hand, facilitate regular cleaning and maintenance of the plug 141, for example, by replacing the oil-absorbing cotton block, quickly clean up the residual smoke oil on the head of the plug 141.
[0064] The anti-leakage atomizer 100 is provided with an anti-leakage unit 14 on the base 11 of the atomizer core 10, which can effectively reduce the probability of smoke liquid leaking from the air inlet 113, thereby alleviating the problem of atomizer leakage.
[0065] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0066] The above embodiments merely represent preferred implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
