In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the invention, whereby the invention is not limited to the specific embodiments disclosed below.

It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

An embodiment of the present invention provides an atomizer 100 for an electronic cigarette, which includes a lower housing 110, a heating component, and an atomization chamber 120 between the lower housing 110 and the heating component, wherein the lower housing 110 is provided with a first air inlet channel 130 for air inlet, which is communicated with the atomization chamber 120, and the first air inlet channel 130 is closed by a pierceable seal 140.

When it is desired to connect the battery assembly 200 to the atomizer 100, the seal 140 may be pierced to place the first air inlet passage 130 in communication with a second air inlet passage (not shown) provided in the battery assembly 200. In this way, air may be introduced into the nebulization chamber 120 from the second air intake channel and the first air intake channel 130. Since the sealing member 140 is not required to be separated from the lower housing 110, the assembly process can be simplified, and the battery assembly 200 and the atomizer 100 can be quickly and conveniently assembled together.

Also, the number of the sealing members 140 of the atomizer 100 of the embodiment of the present invention is small as compared to the conventional atomizer, and the process of assembling the sealing members 140 on the lower housing 110 is simplified. The installation process of the battery assembly 200 is also simplified since the sealing member 140 does not need to be separated from the lower housing 110. The electronic cigarette is more convenient to use as a whole. And the atomizer 100 can be completely sealed in the transportation process, and no liquid leakage occurs.

The second air intake passage of the battery assembly 200 may be provided in various manners.

For example, an air intake hole 240 may be provided at the rear end of the battery assembly 200, and a slit inside the case 250 of the battery assembly 200 forms a second air intake passage, one end of which communicates with the air intake hole 240.

It is understood that the air flow path may be independently provided in the battery assembly 200 to form the second air intake passage, and one end of the second air intake passage communicates with the outside. For example, a second air intake passage may be formed on the battery mount 220.

In this embodiment, the seal 140 may be pierced in a variety of ways.

For example, a single piercing member 210 may be provided, and when it is desired to assemble the battery assembly 200 and the atomizer 100 together, the piercing member 210 may be used to pierce the sealing member 140 to render the first air intake passage 130 conductive. The atomizer 100 and the battery assembly 200 are then assembled together. At this time, the second air intake passage of the battery assembly 200 communicates with the first air intake passage 130, so that air can be introduced into the atomizing chamber 120 from the second air intake passage and the first air intake passage 130. After entering the atomization cavity 120, the air can be mixed with the flue gas in the atomization cavity 120 and discharged to the outside of the atomizer 100 through an exhaust passage and an air outlet 180 arranged in the atomizer 100. The exhaust passage and the air outlet 180 provided in the atomizer 100 may be any of those of the prior art, and are not limited thereto.

Preferably, a penetration member 210 is provided on the battery assembly 200, the penetration member 210 is provided with a connection passage 212, and the penetration member 210 is provided corresponding to the first air inlet passage 130 of the lower housing 110 to penetrate the sealing member 140. After the battery pack 200 is connected to the atomizer 100, the puncture member 210 pierces the sealing member 140, and the first air intake passage 130 communicates with the second air intake passage through the connection passage 212. So configured, when the piercing member 210 pierces the sealing member 140 to establish a connection, that is, the first air inlet channel 130 is communicated with the second air inlet channel through the connecting channel 212, and air can be introduced into the first air inlet channel 130 through the connecting channel 212 on the piercing member 210 and enter the atomizing chamber 120 through the first air inlet channel 130. Therefore, there is no need to provide an additional vent hole in the lower housing 110 for air to flow into the atomizing chamber 120. The specific direction of airflow may be shown with reference to the arrows in fig. 13.

Specifically, the penetration member 210 may be provided at the front end of the battery mount 220 of the battery assembly 200. Accordingly, one end of the first air intake passage 130 penetrates the bottom of the lower housing 110. So configured, during assembly of the battery assembly 200 with the atomizer 100, the piercing element 210 may be inserted into the corresponding first air intake passage 130 and pierce the seal 140 in the first air intake passage 130. After the seal 140 within the first intake passage 130 is pierced, the first intake passage 130 communicates with the connecting passage 212, and the connecting passage 212 communicates with the second intake passage, which allows the first intake passage 130 to communicate with the second intake passage. The second air intake passage of the battery assembly 200 may introduce air into the atomizing chamber 120 via the second air intake passage, the connecting passage 212, and the first air intake passage 130.

The sealing member 140 may include a penetrable sealing portion 141, a positioning flange 142 at one end of the penetrable sealing portion 141, and a flow-guiding channel 143 at the other end of the penetrable sealing portion 141.

The pierceable seal 141 is used to close the first intake passage 130.

The positioning flange 142 is used to firmly fix the sealing member 140 to the lower housing 110. In a specific arrangement, the lower housing 110 is located below the first air inlet channel 130 and may be provided with a positioning slot 150. The positioning flange 142 may be received by the positioning groove 150. So configured, seal 140 does not move relative to first intake passage 130 during penetration of seal 140 with piercing member 210 due to the stop of positioning flange 142 by positioning slot 150.

The above-mentioned flow guide passage 143 communicates with the first air intake passage 130 for introducing air into the first air intake passage 130. If the first intake passage 130 includes an axial intake passage 131 and a radial intake passage 132 communicating with the axial intake passage 131, the above-described flow guide passage 143 may include an axial hole 143a communicating with the above-described axial intake passage 131. On the basis of this, the above-mentioned flow guide passage 143 may further include a radial hole 143b communicating with the axial hole 143a and with the above-mentioned radial intake passage 132.

Further, when the sealing member 140 is disposed, one end of the sealing member 140 forms an insertion end into which the puncture member 210 is inserted, and the other end of the sealing member 140 forms a positioning end 144, and the positioning end 144 may abut against the channel wall 134 corresponding to the end of the first air intake channel 130. Thus, upon insertion of the piercing element 210 into the sealing element 140, the sealing element 140 is subjected to a force directed from the insertion end toward the positioning end, which force causes the sealing element 140 to have a moving actuation. But due to the stop of the positioning end by the channel wall. So that the seal 140 cannot move at this time. Such that the position of seal 140 relative to first intake passage 130 does not change after it has been pierced.

It will be appreciated that the seal 140 described above may be other embodiments.

For example, the seal 140 may include only one pierceable seal 141.

In one embodiment, the sealing member 140 is an elastic sealing member 140. For example, the elastic sealing member 140 may be made of a material such as silicone.

In this way, when the puncture member 210 is disposed on the battery assembly 200, after the puncture member 210 is used to puncture the sealing member 140, the elastic sealing member 140 and the puncture member 210 can form a tight fit, so that the smoke liquid in the atomizer 100 is not easy to flow out from the gap between the puncture member 210 and the elastic sealing member 140, thereby reducing the risk of liquid leakage. Moreover, since the sealing member 140 has elasticity, after the sealing member 140 is pierced, the piercing member 210 is pulled out from the sealing member 140, and the pierced portion of the sealing member 140 can be automatically closed even after a plurality of piercing. Therefore, even if the puncture instrument 210 is pulled out from the inside of the sealing member 140, no leakage is caused.

In one embodiment, the first air inlet channel 130 has an air inlet 133 for introducing air into the atomizing chamber 120, and the air inlet 133 is higher than the bottom of the atomizing chamber 120.

Specifically, the air inlet 133 may be disposed at the bottom of the atomizing chamber 120 and extend into the atomizing chamber 120, and the height of the air inlet 133 is greater than the bottom of the atomizing chamber 120 by a certain distance. This is arranged so that the liquid level of the condensed liquid at the bottom of the atomizing chamber 120 is lower than the height of the air inlet 133, so that this part of the liquid cannot enter the air inlet 133. Since this portion of the liquid cannot enter the air inlet 133, and thus cannot enter the connecting passage 212 of the piercing member 210, it is less likely to enter the battery assembly 200 along the connecting passage 212, and thus the risk of leakage is reduced.

It will be appreciated that the air inlet 133 may also be provided on the side wall of the chamber of the nebulization chamber 120, such that the air inlet 133 may also be located higher than the bottom of the nebulization chamber 120 described above. Moreover, since the newly formed condensed liquid in the atomizing chamber 120 generally moves toward the bottom of the atomizing chamber 120, the air inlet 133 is disposed on the sidewall of the chamber of the atomizing chamber 120, such that the liquid is not easy to enter the air inlet 133, and since the air inlet 133 has continuous air flowing into the atomizing chamber 120, the air flow formed by such air also prevents the condensed liquid from entering the air inlet 133. Thus, since the condensed liquid hardly enters the air inlet 133, and thus cannot enter the connecting passage 212 of the penetrating member 210, and does not enter the battery assembly 200 along the connecting passage 212, the risk of leakage is reduced.

Further, the air inlet 133 is disposed on the sidewall of the chamber of the atomizing chamber 120, so that air can more smoothly enter the atomizing chamber 120. This is because if the air inlet 133 is provided at the bottom of the atomizing chamber 120, more condensate will generally accumulate at the bottom of the atomizing chamber 120, and if this condensate enters the air inlet 133, the air flow at the air inlet 133 will be affected by the condensate due to the problem of condensate accumulation at the time of suction. Resulting in a poor airflow. However, the air inlet 133 is disposed on the sidewall of the chamber of the atomization chamber 120, so as to reduce or even avoid the influence of condensate on the air flow, and further make the air flow smooth and the atomization effect better.

The number of the first air intake passages 130 may be one or more. For example, the number of the first air inlet passages 130 is two, and the two first air inlet passages 130 are respectively located at two opposite sides of the atomizing chamber 120. Accordingly, if the penetration members 210 are provided on the battery assembly 200, the number of penetration members 210 corresponds to the number of first air intake passages 130. This allows for an increased flow of gas into the nebulization chamber 120. And double insurance can be formed, that is, one of the first air inlet channels 130 is blocked due to accident, and the other first air inlet channel 130 can still ensure that air can enter the atomization cavity 120.

In one embodiment, the atomizer 100 further includes a stop structure 160, where the stop structure 160 is used to prevent the seal 140 in the first air intake passage 130 from separating from the first air intake passage 130 under the action of an external force.

By providing the stopper 160, the seal 140 is prevented from being separated from the first intake passage 130 by being separated from the first intake passage 130 when the puncture member 210 is pulled out of the seal 140.

There are various embodiments of the stopper 160, for example, the stopper 160 is located at one side of the sealing member 140, and the stopper 160 restricts the sealing member 140 from moving toward the outside of the first intake passage 130 when the sealing member 140 contacts the stopper 160.

Specifically, the stop structure 160 may include a stop ring 161 and a positioning portion 162 connected to the stop ring 161. The stop structure 160 may be formed by machining a cold rolled carbon steel sheet. The above-mentioned stopper ring 161 may be disposed at the bottom end of the first air intake passage 130 outside the bottom end of the lower housing 110, and a portion of the stopper ring 161 is located at the lower end of the bottom of the sealing member 140. The positioning portion 162 may be fixed in a receiving groove 170 provided on a sidewall of the atomizer 100. Thus, when the puncture element 210 is pulled out from the sealing element 140, the sealing element 140 tends to move downwards, and after the sealing element 140 contacts the stop ring 161, the sealing element 140 is blocked and limited by the stop ring 161, so that the sealing element 140 cannot move continuously. This prevents the sealing member 140 in the first intake passage 130 from being separated from the first intake passage 130 by an external force.

It is understood that the stop structure 160 may be other embodiments. For example, barbs 213 may be provided on the corresponding channel walls of the first intake channel 130 such that after the seal 140 is inserted into the first intake channel 130, the barbs 213 will be inserted into the seal 140. When the seal 140 has a tendency to move under external forces, the barbs 213 will prevent further movement of the seal 140.

The embodiment of the invention also provides a battery assembly. The above-described battery assembly 200 is provided with a second air intake passage for intake air. The battery assembly 200 is further provided with a penetration member 210, the penetration member 210 is provided with a connection passage 212, and the penetration member 210 is provided corresponding to the first air inlet passage 130 of the lower housing 110 to penetrate the sealing member 140. After the battery pack 200 is connected to the atomizer 100, the puncture member 210 pierces the sealing member 140, and the first air intake passage 130 communicates with the second air intake passage through the connection passage 212.

In use, the battery assembly 200 is first connected to the atomizer 100. After the battery pack 200 is connected to the atomizer 100, the puncture member 210 pierces the sealing member 140, and the first air intake passage 130 communicates with the second air intake passage through the connection passage 212. So configured, when the piercing member 210 pierces the sealing member 140 to establish a connection, that is, the first air inlet channel 130 is communicated with the second air inlet channel through the connecting channel 212, and air can be introduced into the first air inlet channel 130 through the connecting channel 212 on the piercing member 210 and enter the atomizing chamber 120 through the first air inlet channel 130. Therefore, there is no need to provide an additional vent hole in the lower housing 110 for air to flow into the atomizing chamber 120.

Specifically, the penetration member 210 may be provided at the front end of the battery mount 220 of the battery assembly 200. During assembly of the battery assembly 200 with the atomizer 100, the piercing element 210 may be inserted into the corresponding first air intake passage 130 and pierce the seal 140 in the first air intake passage 130. After the seal 140 within the first intake passage 130 is pierced, the first intake passage 130 communicates with the connecting passage 212, and the connecting passage 212 communicates with the second intake passage, which allows the first intake passage 130 to communicate with the second intake passage. The second air intake passage of the battery assembly 200 may introduce air into the atomizing chamber 120 via the second air intake passage, the connecting passage 212, and the first air intake passage 130.

In this embodiment, the piercing member 210 includes at least one piercing head 211 disposed toward the sealing member 140, and the connecting channel 212 penetrates the piercing head 211. The shape of the piercing head 211 may be wedge-shaped, triangular, etc. The seal 140 is easier to pierce as long as the piercing head 211 has a sharp end. The number of the piercing heads 211 may be one or two or more. The shape of the connecting channel 212 may be linear, or may be curved or polygonal.

For example, the piercing member 210 may include a support 214, and the support 214 may have a tapered piercing head 211 at one end.

For example, the lancing element 210 may have a generally triangular shape and the corresponding lancing head 211 may have a generally triangular shape.

For example, the piercing member 210 may include a supporting body 214, and the supporting body 214 has a triangular piercing head 211 at one end.

For example, the piercing member 210 may include two spaced apart support bodies 214, each support body 214 having a triangular-shaped piercing head 211 disposed at one end.

For example, piercing member 210 may include two spaced apart wedge-shaped piercing heads 211.

In this embodiment, the outer wall of the piercing member 210 is provided with at least one barb 213 that can be inserted into the sealing member 140. Providing barbs 213 may provide a more secure connection of the piercing element 210 to the sealing element 140. Further, since the puncture member 210 is disposed on the battery assembly 200 and the sealing member 140 is disposed on the atomizer 100, the puncture member 210 is firmly connected with the sealing member 140, so that the connection between the battery assembly 200 and the atomizer 100 is also more stable. The number of barbs 213 may be set according to the actual situation.

The embodiment of the present invention further provides an electronic cigarette 300, where the electronic cigarette 300 includes the atomizer 100 and the battery assembly 200, and the puncture member 210 pierces the sealing member 140 after the battery assembly 200 is connected to the atomizer 100, so as to communicate the first air inlet channel 130 with the second air inlet channel through the connection channel 212.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
