Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomization devices. Background Art

[0002] When the electronic atomizer cartridge atomizes the oil, condensate will form, and the condensate will flow into the condensation chamber. At the same time, some oil leaking from the oil storage tank will also flow into the condensation chamber. The condensation chamber is connected to the air inlet channel of the cartridge, and there is a certain probability that the residual liquid in the chamber will flow out through the air inlet channel. The common condensation chamber will form a raised part at the bottom of the chamber, and the air inlet channel of the cartridge will extend to the raised part, using the height difference to prevent the residual liquid in the chamber from entering the channel. However, when using the cartridge in daily life, the cartridge will be placed at different angles, and the effect of preventing oil leakage by only using the height difference of the raised part is not ideal, so there is room for improvement in the existing cartridges.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0028] See attached Figure 1-3 , shown is a smoke cartridge with anti-leakage oil inlet duct, the smoke cartridge 1 includes a shell body 2, an oil storage tank 3 is formed in the shell body 2, an atomizer core 4 is installed in the oil storage tank 3, a sealing gasket 5 and a base 6 are installed at the lower part of the oil storage tank 3 from top to bottom, a condensation chamber 7 is formed in the base 6, the sealing gasket 5 cooperates with the base 6 to form an airflow channel 8, the air intake section 800 of the airflow channel 8 is connected to the outside, and the exhaust section 801 of the airflow channel 8 is connected to the top of the condensation chamber 7.

[0029] The shell body 2 is generally square, with rounded corners on the edges. An oil storage tank 3 is formed inside the shell body 2, and a sealing gasket 5 and a base 6 are stacked up and down at the bottom by means of tight fitting and snap-fitting. The sealing gasket 5 fits tightly with the inner wall of the shell body 2 to maintain the sealing of the oil storage tank 3. The base 6 below is tightly supported under the sealing gasket 5 to provide stable support. A condensation chamber 7 is formed on the base 6, and the sealing gasket 5 is located above the base 6. The airflow channel 8 is formed by the cooperation of the sealing gasket 5 and the base 6, which makes it easier to set the exhaust section 801 of the airflow channel 8 at the top of the condensation chamber 7. As a result, the exhaust section 801 and the bottom of the condensation chamber 7 have the largest height difference. When the cigarette cartridge 1 is placed at different angles, it is difficult for the residual liquid at the bottom of the cavity to enter the airflow channel 8 through the exhaust section 801 and flow out.

[0030] To further enhance the oil leakage prevention effect, at least a portion of the airflow channel 8 is provided with a plurality of baffles 802 to divide the portion of the airflow channel 8 into a plurality of airflow branches with liquid locking capability. The baffles 802 may be provided only on a portion of the length of the airflow channel 8 or may be provided as a whole. From a comprehensive analysis of cost, effect, etc., it is preferred to provide a plurality of baffles 802 on a portion of the length.

[0031] In order to meet the air flow requirements of the smoke oil atomization, the aperture of the air flow channel 8 is usually slightly larger, and the interior of the air flow channel 8 is divided into multiple air flow branches by a plurality of partitions 802, so that the residual liquid can be locked by using a narrow aperture while ensuring that the air flow can pass through. 2 ), even if the cigarette cartridge 1 falls over, the residual liquid is basically unable to enter, thereby further achieving the purpose of preventing oil leakage.

[0032] In some embodiments, the air inlet section 800 of the air flow channel 8 is formed in the base 6; the upper surface of the base 6 is partially sunken to form an air groove, the air groove is connected between the air inlet section 800 and the condensation chamber 7, and the sealing gasket 5 is sealed above the air groove to form the exhaust section 801.

[0033] The air inlet section 800 of the air flow channel 8 is formed through the base 6, and the exhaust section 801 is formed by the sealing gasket 5 and the base 6. Specifically, a part of the upper surface of the base 6 is sunken to form an air groove with an open top surface, and the open position of the air groove is blocked by the sealing gasket 5, thereby forming the exhaust section 801 connected to the upper part of the condensation chamber 7.

[0034] The sealing gasket 5 may include a gasket body on the top surface and a lower side wall extending downward from the edge of the gasket body. The sealing gasket 5 is inserted into the interior of the shell body 2. The lower side wall is tightly fitted with the inner surface of the shell body 2. The two may be provided with matching concave and convex structures to enhance the connection stability and sealing. The base 6 is inserted into the inner periphery of the lower side wall of the sealing gasket 5. The lower side wall may be provided with a sealing flange that hooks into the hook groove on the surface of the base 6 to enhance the connection stability and sealing of the two.

[0035] In some embodiments, a plurality of the partitions 802 protrude from the groove wall of the gas groove. If the partition 802 is set at a position far away from the condensation chamber 7, the residual liquid may enter the area near the condensation chamber 7 in the air flow channel 8, affecting the air flow. In this embodiment, the partition 802 is set on the groove wall of the gas groove, and the corresponding partition 802 is located at the exhaust section 801 of the air flow channel 8, which can lock the residual liquid at the position closest to the condensation chamber 7. Even if a small amount of residual liquid enters the air flow branch of the exhaust section 801, due to its narrow aperture, the amount of residual liquid entering is very small, and the negative pressure force generated when the user draws can effectively suck it out, and there is a certain probability that the tiny amount of residual liquid will flow along the surface of the corresponding internal structure with the air flow to the atomization core 4 and be atomized again.

[0036] See attached Figure 2-4In some embodiments, the ends of the plurality of partitions 802 form a supporting step 803; the sealing pad 5 is formed with a plug-in cavity 500 for mounting the atomizer core 4, the plug-in cavity 500 extends downward into the base 6 and abuts against the supporting step 803, the plug-in cavity 500 corresponds to the condensation cavity 7 up and down, and a through hole 501 is provided at the bottom of the plug-in cavity 500, and the through hole 501 communicates with the atomizer core 4 and the condensation cavity 7.

[0037] The bottom end of the atomizer core 4 is inserted downward into the plug-in cavity 500 of the sealing pad 5. The installation is stable and the connection between the two has considerable sealing performance. A corresponding cavity-shaped giving structure is formed on the base 6 to accommodate the downward extension of the plug-in cavity 500. A sunken supporting step 803 is constructed by forming a right-angle notch at the end of each partition 802. The outer wall and bottom wall of the plug-in cavity 500 are in contact with the supporting step 803. At the same time, a through hole 501 is formed at the bottom of the plug-in cavity 500. The atomizer core 4 installed in the plug-in cavity 500 is connected to the condensing cavity 7 on the base 6 through the through hole 501.

Further, a sealing member is arranged between the plug 6001 and the slot 6010.

[0039] The base 6 is divided into an upper body 600 and a lower body 601, which is convenient for processing and assembling various structures required on the base 6, such as the condensation chamber 7, the electrode holder 9, etc. The plug 6001 of the upper body 600 is inserted into the slot 6010 of the lower body 601 to enhance the stability of the connection between the two. The air intake section 800 passes through the slot 6010 downward, passes through the plug 6001 upward and connects to the air groove formed on the top of the upper body 600. A sealing sleeve can be configured between the plug 6001 and the slot 6010 to enhance the sealing performance. The upper body 600 and the lower body 601 can be fixed by ultrasonic welding.

[0040] In some embodiments, the top of the condensation chamber 7 is formed in the upper seat body 600, and the bottom of the condensation chamber 7 is formed in the lower seat body 601. The bottom of the condensation chamber 7 is provided with a boss 6011 protruding from its bottom surface, and an electrode seat 9 electrically connected to the atomization core 4 is installed on the boss 6011. The condensation chamber 7 is provided with oil-absorbing cotton at the edge of the boss 6011 to absorb the residual liquid falling to the bottom of the chamber.

[0041] The condensation chamber 7 corresponds to the bottom of the through hole 501, and its top is formed on the upper seat body 600. At the same time, the air groove on the top surface of the upper seat body 600 cooperates with the sealing pad 5 to form the exhaust section 801 of the air flow channel 8, and the exhaust section 801 is connected to the top of the condensation chamber 7. A boss 6011 is set at the bottom of the condensation chamber 7, and a nesting groove is formed in the boss 6011. The electrode seat 9 is tightly nested in the groove, and then electrically connected to the heating wire of the atomizer core 4.

[0042] In some embodiments, a groove body 200 is formed on the outer wall of the shell body 2, and an oil filling hole connected to the oil storage tank 3 is provided in the groove body 200. The oil filling hole is equipped with an oil filling plug 201, and the oil filling plug 201 has a folding end 2010 to open and close the oil filling hole; the base 6 extends a spring piece 10 into the groove body 200, and the movable end of the spring piece 10 abuts against the end face of the folding end 2010 of the oil filling plug 201, and the inner side of the spring piece 10 has an active space 11 for accommodating the pressed spring piece 10.

[0043] A recessed slot 200 is provided on one side wall of the shell 2, and an oil filling hole and an oil filling plug 201 are provided in the slot 200, wherein one end of the oil filling plug 201 is fixed to the bottom of the slot, and the other end is a folding end 2010 for controlling the opening and closing of the oil filling plug 201, and the width of the oil filling plug 201 is equivalent to the width of the slot 200, and if the folding end 2010 is to be operated, it is necessary to apply force from its end face to pick it up. The spring piece 10 extends out from the lower seat 601, enters the slot through the bottom end of the slot 200, until its active end substantially abuts against the end face of the folding end 2010 of the oil filling plug 201, and the outer surfaces of the two are flush, so that the active end of the spring piece 10 interferes with the end face of the folding end 2010, and the user cannot directly apply force to the end face of the folding end 2010.
