Detailed Description

In order to facilitate an understanding of the present application, the present application will be described in more detail below with reference to the accompanying drawings and detailed description. The specific embodiments are to be considered in an illustrative sense, and not a limiting sense. In addition, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings.

An embodiment of the present application provides an atomizer, and an overall structure of the atomizer 100 is shown in fig. 1. Referring to fig. 2 to 4, the atomizer 100 includes a liquid storage portion 110, an atomizing member 120, and a ventilation member 130.

As shown in fig. 2, the liquid storage portion 110 is provided with a liquid storage chamber 111 and a liquid outlet 112. The liquid outlet 112 is communicated with the liquid storage cavity 111, the liquid storage cavity 111 is used for storing liquid matrix, and the liquid matrix in the liquid storage cavity 111 flows from the liquid outlet 112 to the atomization piece 120. The atomizer 120 is disposed adjacent to the liquid outlet 112, and the atomizer 120 heats and atomizes the liquid matrix to form an aerosol. The liquid matrix may comprise, for example, one or more of the components glycerol, propylene glycol, nicotine formulations, fragrances, flavoring additives, and the like, although other types of liquid matrices are also possible.

As shown in fig. 2, the ventilation member 130 is disposed at an end of the liquid storage portion 110 away from the liquid outlet 112, or may be said to be disposed at the top of the liquid storage portion 110, so as to enable ventilation from the top of the liquid storage chamber 111. Referring to fig. 2, a ventilation liquid chamber 131 is provided in the ventilation member 130, and the ventilation liquid chamber 131 is filled with liquid (even liquid indicated by a broken line in fig. 2). The type of liquid here may be consistent with the liquid matrix in the liquid storage chamber 111, or may be other types of liquids. As shown in fig. 2, the surface of the ventilation member 130 is at least partially defined with a first ventilation channel 132 and a second ventilation channel 133. The first ventilation channel 132 communicates with the external atmosphere and the ventilation liquid chamber 131, the second ventilation channel 133 communicates with the ventilation liquid chamber 131 and the liquid storage chamber 111, and the first ventilation channel 132 and the second ventilation channel 133 are isolated by the liquid located in the ventilation liquid chamber 131. As indicated by the arrows in fig. 2, ambient air enters the liquid in the ventilation liquid chamber 131 via the first ventilation channel 132, and the second ventilation channel 133 introduces air above the liquid in the ventilation liquid chamber 131 into the liquid storage chamber 111. The whole process is that the external air enters the liquid in the ventilation liquid cavity 131 and overflows from the liquid into the liquid storage cavity 111, so that ventilation of the liquid storage cavity 111 is realized.

In the above-mentioned atomizer 100 structure, ventilation is performed by setting the liquid seal, and only when the negative pressure in the liquid storage cavity 111 increases and the pressure difference with the external air reaches a predetermined value, the external air can enter the liquid storage cavity 111 through the ventilation liquid, and if the negative pressure in the liquid storage cavity 111 is smaller and the pressure difference with the external air does not reach the predetermined value, ventilation is not performed. Therefore, the liquid sealing structure plays a role of a barrier, separates the liquid storage cavity 111 from the outside air, and can keep a certain initial negative pressure value in the liquid storage cavity 111 to avoid liquid leakage.

Meanwhile, the ventilation member 130 is arranged at the top of the liquid storage part 110, so that ventilation can be performed from the top of the liquid storage cavity 111, and compared with the existing scheme of ventilation from the bottom of the liquid storage cavity 111, the atomizer 100 of the embodiment of the application can avoid ventilation bubbles to block the liquid outlet 112, and ensure that the liquid outlet 112 normally discharges.

The first ventilation channel 132 and the second ventilation channel 133 may have a plurality of structures, and may be grooves or holes integrally formed in the ventilation member 130, or may be a single airway tube mounted on the ventilation member 130. And are not limited herein. In this embodiment, as shown in fig. 2 and 5, the first ventilation channel 132 includes a groove formed on a sidewall of the ventilation liquid chamber 131. The recess extends to the bottom of the ventilation liquid chamber 131 so that ambient air enters the ventilation liquid along the recess.

Further, as shown in fig. 2 and 3, the atomizer 100 further includes a ventilation seal 140. A breather seal 140 is disposed on the breather 130. As shown in fig. 5, the ventilation member 130 is provided with a first opening 134, and the first opening 134 communicates with the ventilation liquid chamber 131. Referring to fig. 2 and 5, a ventilation seal 140 is used to seal the first opening 134. The purpose of the first opening 134 is to facilitate the filling of the ventilation liquid chamber 131 through the first opening 134. At the same time, providing the ventilation liquid chamber 131 in an open-top configuration also facilitates the formation of the entire ventilation member 130.

As shown in fig. 3, the first ventilation channel 132 includes a groove formed on a sidewall of the ventilation liquid chamber 131, so as to ensure that the gas in the groove smoothly enters the ventilation liquid and does not leak out. As shown in fig. 2, 3 and 6, the ventilation sealing member 140 includes a rib 141, where the rib 141 extends from a main body portion of the ventilation sealing member 140 toward the ventilation liquid cavity 131, and as shown in fig. 2 and 3, the rib 141 abuts against a side wall of the ventilation liquid cavity 131 and covers a part of the groove, so that the ventilation sealing member 140 can cover the part of the groove exposed to the ventilation liquid, and gas in the groove is prevented from leaking out above the ventilation liquid before the gas does not enter the ventilation liquid.

It will be appreciated that the first ventilation channel 132 and the second ventilation channel 133 may be defined by the ventilation member 130 and the ventilation sealing member 140 together, or may be holes provided in the ventilation member 130 separately, which is not limited herein.

As shown in fig. 2 and 5, the ventilation member 130 includes a cylindrical portion 135. The cylindrical portion 135 has a hollow structure, and the hollow portion forms at least a part of the second ventilation channel 133. At least part of the second ventilation channels 133 or all of the second ventilation channels 133 are formed by one cylindrical portion 135, so that the second ventilation channels 133 can lead air above the liquid in the ventilation liquid chamber 131 into the liquid storage chamber 111.

The columnar portion 135 may be located in the ventilation liquid chamber 131 or may be located on one side of the ventilation liquid chamber 131. In the embodiment of the present application, as shown in fig. 5, the cylindrical portion 135 is located at one side of the ventilation liquid chamber 131. The top of the cylindrical portion 135 is provided with a horizontally extending communication groove 136, and the communication groove 136 is used for communicating the ventilation liquid cavity 131 with the second ventilation channel 133. As shown in fig. 2, the communication groove 136 guides the air above the ventilation liquid chamber 131 into the second ventilation channel 133.

As shown in fig. 5, the top end of the ventilation member 130 is provided with a vertical first positioning surface 137, and the first positioning surface 137 is used for abutting against the ventilation seal member 140. Referring to fig. 6, the top end of the ventilation seal 140 may also be provided with a vertical second locating surface 142, the second locating surface 142 being for locating in abutment with other parts of the atomizer 100, such as the mouthpiece 150. Thereby enabling the mounting positioning of the breather 130 and the breather seal 140 in the atomizer 100.

As shown in fig. 5, the ventilation member 130 further includes a positioning pin 138. As shown in fig. 2, the locating pin 138 passes through the ventilation seal 140 and is inserted into the mouthpiece 150, thereby further locating the ventilation seal 130 with the ventilation seal 140 and the mouthpiece 150. Referring to fig. 6, the ventilation sealing member 140 is provided with a through hole 143 for being matched with the positioning pin 138, and the suction nozzle 150 is also provided with a corresponding positioning hole for inserting the positioning pin 138.

In other alternative embodiments. As shown in fig. 7, the first ventilation channel 132 may also be defined in part by a locating pin 138. For example, in fig. 7, a vertical groove is formed on the outer wall of the positioning pin 138 to define the first ventilation channel 132. As shown in fig. 7, the outside air enters the liquid storage chamber 131 through the groove on the positioning pin 138. The groove extends vertically on the outer wall of the locating pin 138 to the root of the locating pin 138 so that the groove extends below the liquid level in the liquid reservoir 131. The ribs 141 serve to cover part of the recess, thereby limiting the flow of air directly into the liquid in the liquid reservoir 131.

The first ventilation channel 132 and the second ventilation channel 133 each communicate with the opening of the ventilation liquid chamber 131 at a position within the ventilation liquid chamber 131 facing away from each other. In particular, in order to achieve that the first ventilation channel 132 and the second ventilation channel 133 are always liquid-isolated in the tilted state of the atomizer 100, the openings of the two ventilation channels communicating with the ventilation liquid chamber 131 are located at a position on the ventilation member 130 facing away from each other, for example at the upper and lower ends. As shown in fig. 2, the opening of the first ventilation channel 132 for communicating with the ventilation liquid chamber 131 is located at the bottom of the ventilation liquid chamber 131, and the opening of the second ventilation channel 133 for communicating with the ventilation liquid chamber 131 is located at the top of the ventilation liquid chamber 131, so that the first ventilation channel 132 and the second ventilation channel 133 can be isolated from the liquid in the ventilation liquid chamber 131 all the time in the inclined state of the atomizer 100.

As shown in fig. 2 and 4, the atomizer 100 includes a suction nozzle 150, and the suction nozzle 150 is disposed on the liquid storage portion 110. As shown in fig. 2, the suction nozzle 150 abuts against the ventilation seal 140 to press the ventilation seal 140 against the ventilation member 130. When the suction nozzle 150 is mounted, the suction nozzle 150 is buckled downwards from the top of the liquid storage part 110 to aim at the liquid storage part 110, so that the suction nozzle 150 can be mounted on the liquid storage part 110, and the ventilation sealing piece 140 is pressed tightly by the suction nozzle 150.

As shown in fig. 2, the nebulizer 100 further comprises a reservoir seal 160. A reservoir seal 160 is provided on the reservoir 110. As shown in fig. 4, the liquid storage portion 110 is provided with a second opening 113, and the second opening 113 is communicated with the liquid storage cavity 111. Referring to fig. 2 and 4, the liquid storage chamber seal 160 is used to seal the second opening 113, thereby sealing the liquid storage chamber 111. The provision of the second opening 113 facilitates the filling of the liquid storage chamber 111 through the second opening 113. As shown in fig. 2, the breather 130 is disposed on the reservoir seal 160.

Referring to fig. 2 and 3, the bottom end of the cylindrical portion 135 passes through the reservoir seal 160 and protrudes into the reservoir 111, so that the second ventilation channel 133 communicates with the reservoir 111. Meanwhile, the interference fit between the cylindrical part 135 and the liquid storage cavity sealing member 160 can ensure the complete sealing performance of the liquid storage cavity sealing member 160.

As shown in fig. 2, the atomizer 100 is further provided with an air passage 101, and the air passage 101 is disposed in parallel with the liquid storage chamber 111. The air channel 101 directs the air flow from the bottom of the atomizer 100 to the mouth of the suction nozzle 150. The air channel 101 may be defined by the liquid storage portion 110 and the suction nozzle 150. As indicated by the arrows in fig. 2, the air flow enters from the bottom of the atomizer 100, carries aerosol through the atomizer 120, and exits through the air passage 101 and the mouthpiece 150. As shown in fig. 2, the first ventilation channel 132 communicates with the airway 101, so that air in the airway 101 enters the ventilation liquid chamber 131 for ventilation of the liquid storage chamber 111.

In the embodiment of the atomizer, the liquid in the ventilation liquid chamber 131 can be prevented from leaking out by setting the diameters of the first ventilation channel 132 and the second ventilation channel 133 smaller, and the liquid substrate in the liquid storage chamber 111 can be prevented from entering the ventilation liquid chamber 131. The diameters of the first ventilation channel 132 and the second ventilation channel 133 are in the order of millimeters or less, and only gas can pass through, and liquid cannot enter. Alternatively, other liquid leakage preventing structures may be provided to prevent liquid leakage, for example, a gas-permeable waterproof film, such as an eptfe film (expanded polytetrafluoroethylene film), which is gas-permeable and prevents liquid leakage, may be provided in the first ventilation channel 132 and the second ventilation channel 133, without limitation.

The electronic atomizing device comprises the atomizer 100, and further comprises a battery assembly for supplying power to the atomizer 100. The battery assembly may be configured to be removably coupled to the atomizer 100.
