Background

At present, almost all atomizers in the market discharge air from a central tube, but with the development of thinning and lightening of electronic cigarettes, the gap between the central tube and the inner wall surface of a shell is narrower and narrower. The gap between the central tube and the inner wall surface of the shell is used for communicating the liquid storage cavities at the left side and the right side of the central tube, and the height of the substrate which can be atomized at the two sides is balanced.

In the atomizing base 20 disclosed in at least one embodiment of the present application, a cross section of the atomizing base 20 includes a first longitudinal axis and a first transverse axis, and the atomizing base 20 is provided with a liquid outlet channel 21 and a first air exchange channel 22. In the embodiment of the present application, the cross section of the atomizing base 20 is an ellipse or an ellipse-like, the first longitudinal axis is the long axis of the atomizing base, and the first transverse axis is the short axis of the atomizing base. The liquid outlet channel 21 and the first ventilation channel 22 are respectively disposed on two opposite sides of the first transverse axis, for convenience of description, the two opposite sides of the first transverse axis are respectively named as a first side and a second side, wherein the liquid outlet channel 21 is located on the first side, and the first ventilation channel 22 is located on the second side. The outlet channel 21 is used for discharging the nebulizable matrix in the reservoir 30. The first ventilation channel 22 is used for balancing the pressure in the reservoir 30 and preventing the nebulizable matrix in the reservoir 30 from being discharged from the outlet channel 21. In other embodiments, the cross-section of the atomizing base 20 can also be circular or square, and the first longitudinal axis and the first transverse axis have the same length; the cross-section of the atomizing base 20 may be rectangular, and the first longitudinal axis is the length direction of the atomizing base 20, and the first transverse axis is the width direction of the atomizing base 20. It is to be understood that the above description is intended to be illustrative only and is not intended to be limiting.

In actual use, when the nebulizable matrix is consumed for use, on the one hand, the nebulizable matrix in the reservoir 30 of the first side can flow out from the outlet channel 21 for nebulization; on the other hand, the volume of the outflow portion can be filled with nebulizable matrix in reservoir 30 of the second side while reservoir 30 of the second side is ventilated to equalize pressure via first ventilation channel 22. In this manner, reservoir 30 on the second side is preferentially occupied by air, and incomplete consumption of the nebulizable matrix within reservoir 30 on the second side is not expected.

In some embodiments, the atomizing base 20 further defines a second air vent channel (not shown), and the second air vent channel and the outlet channel 21 are located on the same side of the first transverse axis, that is, both are located on the first side. Specifically, the second ventilation channel may be in communication with the liquid outlet channel 21, or may be directly used for communication with the liquid storage chamber 30.

In practical use, after the nebulizable substrate in the reservoir 30 flows out from the liquid outlet channel 21, the air outside the nebulizer 100 can enter the reservoir 30 through the first ventilation channel 22 and the second ventilation channel to balance the pressure inside the reservoir 30 and prevent uneven liquid outlet.

In a preferred embodiment, the radial cross-sectional area of the first scavenging passage 22 is less than the radial cross-sectional area of the second scavenging passage. Specifically, the larger the radial sectional area is, the stronger the air circulation capacity of the ventilation channel per unit time is; the smaller the radial cross-sectional area, the weaker the air flow capacity per unit time of the ventilation channel.

In practical use, the first ventilation channel 22 is connected to the reservoir 30 on the first side, and the second ventilation channel is connected to the reservoir 30 on the second side. Since the radial cross-sectional area of the first ventilation channel 22 is less than the radial cross-sectional area of the second ventilation channel, air will still preferentially pass through the second ventilation channel into the reservoir 30 on the second side. Thus, when the nebulizable substrate in reservoir 30 of the first side is consumed, the nebulizable substrate in reservoir 30 of the second side will flow into reservoir 30 of the first side, and the second ventilation channel will equalize the pressure in reservoir 30.

In a preferred embodiment, the axial length of the first scavenging passage 22 is greater than the axial length of the second scavenging passage. Specifically, the longer the axial length of the ventilation channel, the greater the resistance to air circulation; the shorter the axial length of the ventilation channel, the less resistance to the air circulation is created.

In practical use, the first ventilation channel 22 is connected to the reservoir 30 on the first side, and the second ventilation channel is connected to the reservoir 30 on the second side. Since the axial length of the first ventilation channel 22 is greater than the axial length of the second ventilation channel, air will preferentially enter the reservoir chamber 30 on the second side through the second ventilation channel. As such, when the nebulizable substrate within reservoir 30 of the first side is consumed, the nebulizable substrate within reservoir 30 of the second side may flow into reservoir 30 of the first side and the second ventilation channel may equalize the pressure within reservoir 30.

As the same concept of the present application, there is also provided an atomizer 100, the atomizer 100 including a housing 10 and an atomizing base 20. The cross-sectional shape of the atomizing base 20 can be oval, quasi-oval, circular, square, or rectangular, having a first longitudinal axis and a first transverse axis. The cross-sectional shape of the housing 10 matches the cross-sectional shape of the atomizing base 20 and has a second longitudinal axis matching the first longitudinal axis and a second transverse axis matching the first transverse axis. The atomizing base 20 is coupled to the housing 10 and has a mounting cavity 23.

Atomizing seat 20 and the inside definition of casing 10 form liquid storage cavity 30, and liquid storage cavity 30 is used for storing the matrix that can atomize, and liquid storage cavity 30 includes first subchamber 31 and second subchamber, and first subchamber 31 and second subchamber 32 are located the relative both sides of second cross axle and communicate each other. Specifically, reservoir 30 is divided into a first sub-chamber 31 on one side and a second sub-chamber 32 on the other side, with the second lateral axis being the dividing line.

The liquid outlet channel 21 of the atomizing base 20 communicates with the first sub-cavity 31 and the mounting cavity 23, and the first air exchange channel 22 of the atomizing base 20 communicates with the second sub-cavity 32 and the atmospheric pressure. In other embodiments, the atomizer 100 further comprises a seal 50 coupled to the atomizing base 20, the seal 50 and the interior of the housing 10 defining the reservoir 30. The sealing element 50 is provided with a third ventilation channel 51, and the third ventilation channel 51 is communicated with the first ventilation channel 22 and the second sub-cavity 32. Specifically, the sealing member 50 may be a sealing silicone.

Further, the atomizer 100 further includes an atomizing core 40 disposed in the mounting cavity 23, the atomizing core 40 has a liquid absorbing surface 41, and the liquid outlet channel 21 is communicated between the first sub-cavity 31 and the liquid absorbing surface 41. Specifically, the atomizing surface further has an atomizing surface disposed opposite to the liquid absorbing surface 41, the liquid absorbing surface 41 is used for absorbing the nebulizable substrate flowing from the liquid outlet channel 21, and the atomizing surface is used for atomizing the nebulizable substrate to form aerosol for a user to inhale. More specifically, the liquid suction surface 41 is parallel to the axial direction of the liquid outlet passage 21.

In practical use, the nebulizable matrix in the first sub-chamber 31 flows to the nebulizing core 40 through the liquid outlet channel 21 and is nebulized by the nebulizing core 40, meanwhile, the nebulizable matrix in the second sub-chamber 32 flows into the first sub-chamber 31, and simultaneously, the air outside the nebulizing base 20 enters the second sub-chamber 32 through the first air exchanging channel 22 to balance the pressure in the liquid storage chamber 30. In this manner, the second sub-chamber 32 will be preferentially occupied by air, and there will be no situation where the nebulizable substrate within the first sub-chamber 31 is completely consumed, and the nebulizable substrate within the second sub-chamber 32 is incompletely consumed.

In some embodiments, the cross-sectional area of the first scavenging channel 22 decreases from the inlet end of the first scavenging channel 22 toward the outlet end of the first scavenging channel 22. Specifically, the cross-sectional area of the first ventilation channel 22 is linearly decreased from the air inlet end of the first ventilation channel 22 to the air outlet end of the first ventilation channel 22; alternatively, the cross-sectional area of the first ventilation channel 22 is gradually decreased from the air inlet end of the first ventilation channel 22 to the air outlet end of the first ventilation channel 22. In actual use, the first ventilation channel 22 is arranged to facilitate the air in the atmospheric pressure to enter the second sub-cavity 32. It is to be understood that the above description is intended to be illustrative only and is not intended to be limiting.

Further, the atomizer 100 further includes a central tube 11, the central tube 11 is located on the second transverse axis, and in the axial direction of the second transverse axis, a gap between the central tube 11 and the inside of the housing 10 defines a liquid passing channel 12, and the liquid passing channel 12 communicates the first sub-cavity 31 and the second sub-cavity 32. In particular, the nebulizable substrate in the first sub-chamber 31 flows out of the liquid outlet channel 21, and the nebulizable substrate in the second sub-chamber 32 can flow into the first sub-chamber 31 through the liquid passage 12. In this manner, the problem of the non-exhaustible matrix within second subchamber 32 being completely consumed can be avoided.

As a similar concept of the present application, there is also provided an electronic atomizer including the atomizer 100 and a power supply module, wherein the atomizer 100 is the atomizer 100 of the above-described embodiment, and the power supply module is electrically connected to the atomizer 100.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
