The sealing portion 200 and the liquid collecting portion 300 are provided on the base 100. The substrate 100 has a smoke channel 110 and a smoke channel 120. The sealing portion 200 is provided on the top of the base 100, and an edge portion of the sealing portion 200 is adapted to be in sealing abutment with an inner wall of the case cover 40. The liquid collecting part 300 is arranged around the side wall of the base body 100, a plurality of annular liquid collecting grooves 310 are formed in the side face of the liquid collecting part 300, and each annular liquid collecting groove 310 is arranged around the base body 100. The sealing part 200 and the liquid collecting part 300 are made of silicone.
The heat-generating cover structure 10 of the cartridge described above is configured such that the sealing portion 200 and the liquid collecting portion 300 are supported by the base body 100, and the edge portion of the sealing portion 200 is brought into sealing contact with the inner wall of the case cover 40, thereby preventing the oil smoke from leaking into the case cover 40. The soot leaked between the edge portion of the sealing portion 200 and the inner wall of the case cover 40 is collected by each annular liquid collecting groove 310 of the liquid collecting portion 300. The leaked tobacco tar is filled into each annular liquid collecting groove 310, so that the leakage phenomenon of the tobacco tar is effectively delayed. By utilizing the characteristic that silica gel is easy to absorb grease, the collection effect of leaked tobacco tar is improved. Because the liquid collecting part 300 made of the silica gel material is easy to process and manufacture, the thin liquid collecting part 300 is easy to manufacture, the depth of each annular liquid collecting groove 310 is easy to increase, and the leakage phenomenon of the tobacco tar is further delayed.
The base body 100 is used to carry the sealing portion 200 and the liquid collecting portion 300. In one embodiment, the substrate 100 is made of plastic. The tobacco tar stored in the case cover 40 of the cartridge enters the heat generating member 30 through the base 100, and specifically, the tobacco tar flows toward the heat generating member 30 through the tobacco tar passage 110 of the base 100.

Specifically, the edge of the sealing portion 200 is in sealing contact with the inner wall of the housing cover 40, thereby achieving structural sealing and preventing the oil smoke in the housing cover 40 from spilling. In this embodiment, the sealing portion 200 is sleeved on the top of the base 100, and only two input ends of the smoke channel 110 and the output end of the smoke channel 120 of the base 100 are exposed, thereby ensuring the connection stability between the sealing portion 200 and the base 100.
The liquid collecting part 300 serves to delay the leakage of the soot from between the edge portion of the sealing part 200 and the inner wall of the case cover 40. Specifically, the soot leaked between the edge portion of the sealing portion 200 and the inner wall of the case cover 40 is collected by each annular liquid collecting groove 310 of the liquid collecting portion 300. The leaked tobacco tar is filled into each annular liquid collecting groove 310, so that the leakage phenomenon of the tobacco tar is effectively delayed. By utilizing the characteristic that silica gel is easy to absorb grease, the collection effect of leaked tobacco tar is improved. Because the liquid collecting part 300 of silica gel material is easy to process and manufacture, the thin liquid collecting part 300 is easy to manufacture, the depth of each annular liquid collecting groove 310 is easy to promote, the capillary phenomenon is fully exerted, the condensed water and the tobacco tar are not easy to leak, and the leakage phenomenon of the tobacco tar is further delayed.
Further, in order to reduce the part quantity of the top cap structure that generates heat, promote the preparation convenience, reduce the production degree of difficulty, the installation stability of reinforcing collection liquid portion 300. In one embodiment, the sealing portion 200 is integrally formed with the liquid collecting portion 300. Thus, the sealing part 200 is not easily separated from the liquid collecting part 300, and the structural strength is improved. Meanwhile, the sealing part 200 and the liquid collecting part 300 which are both made of rubber are easy to manufacture and form in the same process, are beneficial to production and manufacture, reduce the production difficulty and improve the manufacturing convenience. In addition, the number of parts of the heat generating top cover structure is further reduced.

Meanwhile, the heating top cover is also provided with a valve cover 210 to block the tobacco tar when the user does not smoke the electronic cigarette. Specifically, when the user sucks the electronic cigarette, the valve cover 210 is pushed open due to the air pressure difference, so that the air pressure is balanced and the tobacco tar can flow to flow into the heat generating member 30. When the user does not smoke the e-cigarette, the valve cover 210 will close off the valve hole 130. The structure and the principle of the heating component of the cartridge of the electronic cigarette can refer to the prior art, and are not described herein again.
