[0046] In order to facilitate the understanding of the present application, the present application is described in more detail below with reference to the accompanying drawings and specific implementation methods.

[0047] The embodiment of the present application provides an atomizer. The atomizer 10 is used for electronic atomization devices such as electronic cigarettes. Figures 1 to 6 The atomizer 10 includes a liquid storage part 100, an atomizer seat 200, a ventilation channel 300 and a recovery channel 400. The liquid storage part 100 is provided with a liquid storage chamber 101, and the liquid storage chamber 101 is used to store the e-liquid. The atomizer seat 200 is provided at one end of the liquid storage part 100. Specifically, Figure 2 As shown, the liquid storage member 100 is provided with a suction nozzle 102. The end of the liquid storage member 100 provided with the suction nozzle 102 is a proximal end A, and the end away from the suction nozzle 102 is a distal end B. The distal end B of the liquid storage member 100 is open, and the atomizer seat 200 is provided at the distal end B of the liquid storage member 100, thereby sealing the liquid storage chamber 101.

[0048] like Figure 2 and Figure 3 As shown, the atomizer seat 200 is arranged below the liquid storage chamber 101, combined with Figures 4 to 8The atomizer seat 200 has a first end a located near the liquid storage chamber 101 and a second end b located away from the liquid storage chamber 101. The second end of the atomizer seat 200 is provided with a mounting groove 201 recessed toward the first end. The mounting groove 201 is in fluid communication with the liquid storage chamber 101. An atomizer core 500 is mounted in the mounting groove 201. The e-liquid in the liquid storage chamber 101 flows to the atomizer core 500 in the mounting groove 201, where it is heated and atomized to form an aerosol, or smoke.

[0049] like Figure 10 As shown, the ventilation channel 300 is at least partially disposed on the atomizer seat 200, with one end of the ventilation channel 300 connected to the liquid storage chamber 101 and the other end connected to the atmosphere outside the liquid storage chamber 101, thereby introducing the atmosphere outside the liquid storage chamber 101 into the liquid storage chamber 101 to balance the negative pressure in the liquid storage chamber 101. The ventilation channel 300 is at least partially disposed on the atomizer seat 200, which means that the ventilation channel 300 can be completely disposed on the atomizer seat 200, or a portion thereof can be disposed on the atomizer seat 200 and the other portion can be disposed on other parts, such as Figure 10 As shown, the other part is disposed on the base 700 .

[0050] During use of the electronic cigarette, the liquid in the liquid storage chamber 101 continuously flows to the atomizer core 500, and the liquid in the liquid storage chamber 101 continuously decreases, resulting in a large negative pressure in the liquid storage chamber 101. The large negative pressure makes it difficult for the liquid in the liquid storage chamber 101 to flow out. Therefore, the ventilation channel 300 is provided to replenish air in the liquid storage chamber 101 to avoid a large negative pressure in the liquid storage chamber 101.

[0051] Combine Figure 6 and Figure 7 As shown, one end of the recovery channel 400 is connected to the ventilation channel 300, as shown in FIG. Figure 7 As shown, the other end of the recovery channel 400 is connected to the mounting groove 201 to recover the condensed liquid in the ventilation channel 300 to the atomizer core 500. The condensed liquid in the ventilation channel 300 flows through the recovery channel 400 to the atomizer core 500 in the mounting groove 201 for recycling. This not only helps to improve the utilization rate of the e-liquid, but also prevents the condensed liquid from being retained in the ventilation channel 300 and causing blockage of the ventilation channel 300, and also prevents the ventilation channel 300 from leaking.

[0052] In one embodiment, Figure 2 and Figure 3 As shown, the atomizer seat 200 is provided with a liquid leakage channel 202, which connects the mounting groove 201 and the liquid storage chamber 101, so that the smoke oil in the liquid storage chamber 101 flows from the liquid leakage channel 202 to the atomizer core 500. Figure 3 、 Figure 4 、 Figure 6 and Figure 7As shown, the ventilation channel 300 includes a middle portion 310 and a first communication portion 320. Figure 7 As shown, the middle part 310 is a groove provided on the outer wall of the atomizer seat 200, and the first connecting part 320 is a hole body that passes through the side wall of the atomizer seat 200, similar to opening a ventilation hole on the atomizer seat 200. One end of the first connecting part 320 extends to the outside of the atomizer seat 200 to communicate with the middle part 310, and the other end extends to the leakage channel 202, so that the first connecting part 320 connects the middle part 310 of the ventilation channel 300 with the leakage channel 202, and the leakage channel 202 is connected with the liquid storage chamber 101, so that the ventilation channel 300 is connected with the liquid storage chamber 101. The above structure is designed to connect the ventilation channel 300 to the liquid storage chamber 101 through the hole that passes through the side wall of the atomizer seat 200, rather than directly extending the middle part 310 of the ventilation channel 300 directly to the top of the atomizer seat 200 to connect the ventilation channel 300 to the liquid storage chamber 101. As shown Figure 3 As shown, a sealing sleeve 600 is also provided on the atomizer seat 200 to seal the gap between the atomizer seat 200 and the liquid storage member 100. A hole is designed to penetrate the side wall of the atomizer seat 200 to connect the ventilation channel 300 to the liquid storage chamber 101, rather than directly extending the middle portion 310 of the ventilation channel 300 to the top of the atomizer seat 200. This prevents the sealing sleeve 600 from covering the ventilation port of the ventilation channel 300. The design of the first connecting portion 320 in the form of a hole also helps improve ventilation efficiency, and the ventilation hole has a large ventilation capacity.

[0053] In one embodiment, Figure 6 As shown, the recovery channel 400 is a hole that passes through the side wall of the atomizer seat 200. Figure 8 As shown, one end of the recovery channel 400 extends to the outside of the atomizer base 200 to connect the recovery channel 400 to the ventilation channel 300, and the other end of the recovery channel 400 extends to the mounting groove 201, so that the recovery channel 400 can recover the condensate to the atomizer core 500 in the mounting groove 201 for continued use. Opening a hole in the atomizer base 200 to serve as the recovery channel 400 simplifies the opening of the recovery channel 400, shortens the path, and makes recovery faster.

[0054] Combine Figure 6 and Figure 7 In one embodiment, the atomizer seat 200 includes a groove portion 210, a liquid leakage portion 220 and a mounting portion 230. The liquid leakage portion 220 and the mounting portion 230 are both located on one side of the groove portion 210 close to the liquid storage chamber 101. Figure 6 As shown, it can also be said that the liquid leakage portion 220 and the mounting portion 230 are arranged above the groove portion 210. Figure 7 and Figure 8As shown, the groove portion 210 is provided with a mounting groove 201, with the groove opening of the mounting groove 201 facing downward. The leakage portion 220 is provided with a leakage channel 202, which extends longitudinally to connect the liquid storage chamber 101 and the mounting groove 201. Figure 3 As shown, the liquid storage chamber 101 is provided with an air pipe 110, and the mounting portion 230 of the atomizer seat 200 is used to mount the air pipe 110. Figure 3 As shown, the air pipe 110 is inserted into the mounting portion 230. Figure 9 As shown, there is a gap d between the mounting portion 230 and the groove portion 210, and the air pipe 110 is connected to the gap d. Figure 9 As shown, a first notch 211 is provided on the side of the groove portion 210. Figure 3 and Figure 9 The atomized smoke enters the air pipe 110 from the side of the atomizer seat 200 where the atomizer core 500 is provided, through the first notch 211 and the gap d. Figure 7 As shown, the X direction, Y direction and Z direction are defined. The X direction, the X direction, the Y direction and the Z direction are perpendicular to each other to form a spatial coordinate system. The Z direction is the longitudinal direction of the atomizer seat 200, which is also the longitudinal direction of the atomizer 10. The longitudinal direction is also the vertical direction. Figure 7 and Figure 8 As shown, the groove portion 210 is provided with first notches 211 on both sides along the X direction, the mounting portion 230 is basically located directly above the groove portion 210, and there are two leakage portions 220, which are respectively provided at both ends of the mounting portion 230 along the Y direction.

[0055] like Figure 8 and Figure 9 As shown, the back of the groove portion 210 is provided with a guide rib 212, which can guide the condensed liquid to the atomizing core 500. Specifically, as Figure 9 As shown, the back of the groove portion 210 is concave with high ends and low middle, so that the condensate is gathered in the middle. Figure 7 and Figure 9 As shown, the guide rib 212 includes a first guide rib 2121 and a second guide rib 2122. The first guide rib 2121 is provided at both ends of the back of the groove portion 210, and the first guide rib 2121 extends toward the middle of the groove portion 210, thereby guiding the condensate to the middle of the back of the groove portion 210. The second guide rib 2122 is provided at the middle position of the back of the groove portion 210, and the second guide rib 2122 extends from the back of the groove portion 210 through the side wall of the groove portion 210 to the bottom of the groove portion 210, thereby guiding the condensate to the mounting groove 201, and the condensate can flow to the atomizer core 500 in the mounting groove 201 for reuse. At the same time, as Figure 8 As shown, a drainage groove 213 is formed on the side wall and / or the back of the groove-shaped portion 210 , and the drainage groove 213 can guide the condensed liquid to the installation groove 201 .

[0056] In one embodiment, Figure 2 As shown, the atomizer 10 further includes a base 700. The base 700 is disposed at one end of the atomizer seat 200 away from the liquid storage chamber 101, as shown in FIG. Figure 2 , it can also be said that the base 700 is arranged at the lower end of the atomizing seat 200. Figure 2 and Figure 10 As shown, there is a gap between the base 700 and the atomizing seat 200 to form an atomizing chamber 701. Figure 2 , the atomizing core 500 faces the atomizing chamber 701, and the atomizing chamber 701 provides space for the atomizing core 500 to atomize the e-liquid. Figure 10 As shown, the first notch 211 is connected to the atomizing chamber 701, and the Figure 2 The base 700 is provided with an air inlet 702 connected to the atomizing chamber 701. Figure 2 、 Figure 9 and Figure 10 When the airflow enters the atomizing chamber 701 from the air inlet 702, it takes away the smoke in the atomizing chamber 701 and flows from the first notch 211 to the gap d between the mounting portion 230 and the groove portion 210 of the atomizing seat 200, and enters the air pipe 110 through the gap d, and then is transported outward from the air pipe 110. Figure 2 As shown, the air tube 110 is connected to the suction nozzle 102 on the top of the liquid storage part 100 , and the smoke in the air tube 110 is inhaled by the user through the suction nozzle 102 .

[0057] refer to Figure 6 and Figure 7 As mentioned above, the ventilation channel 300 includes a middle portion 310 and a first connecting portion 320. In one embodiment, Figure 10 As shown, the ventilation channel 300 further includes a second connecting portion 330, which is provided on the outer wall of the base 700. The second connecting portion 330 is a groove structure provided on the outer wall of the base 700. Figure 10 As shown, one end of the second connecting portion 330 is connected to the middle portion, and the other end is connected to the atomizing chamber 701. After the outside air enters the atomizing chamber 701 through the air inlet 702 on the base 700, a portion of it enters the leakage channel 202 through the second connecting portion 330, the middle portion 310, and the first connecting portion 320, and then enters the liquid storage chamber 101 through the leakage channel 202, thereby replenishing air in the liquid storage chamber 101 and balancing the negative pressure in the liquid storage chamber 101. The ventilation channel 300 includes the second connecting portion 330 disposed on the base 700, making it easier for the ventilation channel 300 to connect to the atomizing chamber 701.

[0058] In the embodiment of the present application, the ventilation channel 300 is connected to the external atmosphere through the atomizing chamber 701. The external atmosphere first enters the atomizing chamber and then enters the ventilation channel 300. In other embodiments, the ventilation channel 300 can also be directly connected to the external atmosphere, which is not limited here.

[0059] like Figure 10 As shown, the side wall of the base 700 is provided with a second notch 703, the second notch 703 is connected to the atomizing chamber 701, and the second connecting portion 330 extends to the second notch 703 to connect to the atomizing chamber 701 through the second notch 703. The second notch 703 is provided to provide a wider space for the second connecting portion 330 to connect to the atomizing chamber 701. Figure 10 As shown, the second connecting portion 330 includes a plurality of air channels extending horizontally along the outer side wall of the base 700. The plurality of air channels extend along the circumference of the base 700. One end of the plurality of air channels extends to the second notch 703, and the other ends are connected and merged with each other. In other words, the plurality of air channels are connected, and the merged air channels are connected to the middle portion 310. In this way, each of the plurality of air channels is connected to the second notch 703, and the air intake area is increased. Therefore, the second notch 703 can provide a wider space for the second connecting portion 330 to connect to the atomizing chamber 701.

[0060] In one embodiment, Figure 3 As shown, the atomizer 10 also includes an oil baffle 710. The oil baffle 710 is disposed on the base 700 and above the air inlet 702. The oil baffle 710 prevents condensation from falling into the air inlet 702. During actual assembly, the atomizer 10 has a battery rod below it, meaning the air inlet 702 is connected to the interior of the battery rod below. Without the oil baffle 710, condensation would fall from the air inlet 702 into the battery rod below, damaging the battery, control panel, and other electrical components within the battery rod.

[0061] like Figure 2 and Figure 3 As shown, oil-absorbing cotton 720 is provided at both ends of the oil baffle 710, so that the condensed liquid falling on the oil baffle 710 is absorbed by the oil-absorbing cotton 720 at both ends to avoid oil leakage. Figure 2 As shown, the oil baffle 710 is higher in the middle and lower at both ends, so that the condensate flows to both ends and is absorbed by the oil-absorbing cotton 720.

[0062] like Figure 6 As shown, the middle portion 310 includes multiple air passages extending horizontally along the outer wall of the atomizer seat 200, and the multiple air passages are connected. Specifically, gaps can be provided on the partitions between adjacent air passages to connect adjacent air passages, so that all air passages are connected to each other. The connection between the air passages is conducive to improving the circulation efficiency of the airflow.

[0063] This application also discloses an electronic atomization device. The electronic atomization device can be an electronic cigarette. The electronic atomization device includes the atomizer 10 described above and a battery rod. The atomizer 10 is fixedly or detachably connected to the battery rod. The atomizer core 500 of the atomizer 10 is electrically connected to the battery in the battery rod, so that the battery powers the atomizer core 500.

[0064] Specifically, refer to Figure 3 and Figure 4 The base 700 is provided with a terminal 730, and the atomizer core 500 is provided with a heating circuit. One end of the terminal 730 abuts against the heating circuit of the atomizer core 500, and the other end of the terminal is used to connect to the battery. After the atomizer 10 is connected to the battery rod, the terminal 730 can be electrically connected to the battery. By providing the terminal 730 on the base 700, the atomizer core 500 and the battery are electrically connected.
