Patent Description:
In the existing electronic atomizing device, a leak of e-liquid when the user inhales an aerosol is a common pain point in the industry. One of the main reasons for the leak is insufficient sealing of the atomizing chamber. This causes the e-liquid in the cartridge to permeate into the atomizing chamber during suction, and the e-liquid is drawn into the central tube, resulting in a phenomenon of the leak. Another reason for the leak is that the condensate of the cigarette gas forms an oil film in the central tube. The oil film is difficult to break and is easily sucked into the mouth of users during suction. Such electronic atomizing devices are known, e.g. from <CIT>, <CIT>, <CIT>, <CIT>, <CIT> or <CIT>.

The present invention provides an electronic atomizing assembly as defined in claim <NUM> and an electronic atomizing device as defined in claim <NUM> to solve the problem of a leak of e-liquid when the user inhales an aerosol in the existing technology.

According to the present invention, an electronic atomizing assembly is provided. The assembly includes: a cartridge, a heating cover, and a heating base. The heating cover defines a first groove, and a side wall of the first groove defines a receiving groove. The heating base defines a second groove and the first groove and the second groove form an atomizing chamber. A side wall of the second groove is provided with a protrusion member, and the protrusion member is received in the receiving groove. The protrusion member and the receiving groove are cooperatively used to realize the sealing between the cartridge and the atomizing chamber.

In some embodiments, the grooving direction of the receiving groove is the same as the grooving direction of the first groove, and the height direction of the protrusion member is the same as the grooving direction of the second groove.

In some embodiments, the side walls of the first groove include a first side wall, a second side wall, a third side wall, and a fourth side wall. The first side wall is opposite to the third side wall, and the second side wall is opposite to the fourth side wall.

The side walls of the second groove include a fifth side wall, a sixth side wall, a seventh side wall, and an eighth side wall. The fifth side wall is opposite to the seventh side wall, and the sixth side wall is opposite to the eighth side wall. The sixth side wall is provided with a first protrusion member, and the eighth side wall is provided with a second protrusion member.

In some embodiments, the first side wall defines a first notch, and the third side wall defines a second notch. One end of the first receiving groove extends to the first side wall and is close to the first notch, and the other end of the first receiving groove extends to the third side wall and is close to the second notch. One end of the second receiving groove extends to the first side wall and close to the first notch, and the other end extends of the second receiving groove to the third side wall and close to the second notch. The fifth side wall defines a third notch, and the seventh side wall defines a fourth notch. One end of the first protrusion member extends to the fifth side wall and is close to the third notch, and the other end of the first protrusion member extends to the seventh side wall and is close to the fourth notch. One end of the second protrusion member extends to the fifth side wall and is close to the third notch, and the other end of the second protrusion member extends to the seventh side wall is close to the fourth notch.

The bumps <NUM> may be disposed on the entire circumference of the side wall of the through-hole <NUM> or may be disposed on a certain section of the side wall of the through-hole <NUM>. The cross-section of the bump <NUM> may be square, triangle, arc, or other shapes, and only needs to make the side wall of the through-hole <NUM> uneven. The cross-sectional shape and size of the plurality of bumps <NUM> can be the same or different, and only the side wall of the through-hole <NUM> needs to be uneven. A certain section of the side wall of the through-hole <NUM> is provided with the plurality of bumps <NUM>, or the cross-sectional shape and size of the plurality of bumps <NUM> are different so that the through-hole <NUM> defines an asymmetric structure, which makes the liquid film easier to break, in some embodiments being the asymmetric structure.

By arranging a plurality of bumps <NUM> on the side wall of the through-hole <NUM>, the side wall of the through-hole <NUM> is uneven, which avoids the formation of a liquid film at the through-hole <NUM> after the accumulation of condensate during the use of the atomizer, and prevents the phenomenon of the leak, and the performance of the atomizer is improved.

The cross-section of the groove <NUM> may be square, triangle, arc, or other shapes, and only needs to make the side wall of the through-hole <NUM> uneven. The cross-sectional shape and size of the plurality of grooves <NUM> may be the same or different, as long as the side wall of the through-hole <NUM> is uneven. A certain section of the side wall of the through-hole <NUM> defines multiple grooves <NUM>, or the cross-sectional shape and size of the multiple grooves <NUM> are different so that the through-hole <NUM> defines an asymmetric structure, making the liquid film easier to rupture.
