Description

FIELD OF THE INVENTION

The present invention is in the field of electronic cigarette atomizer technology.

DISCUSSION OF RELATED ART

The prior art has a variety of distinct disadvantages concerning current design of electronic cigarette atomizers. First, E-liquids leak out easily. The air intake hole of current atomizing chambers and the air flow control valves, which are connected with each other, are set in the lower part of the atomizing chamber. This makes it easy for the e-liquid to leak out to the surface of the atomizer through the air intake hole and the air flow control valve. Additionally, the e-liquid can be aspirated into the mouth inadvertently. Secondly, there are no independent e-liquid fill holes concerning current electronic cigarette atomizers on market. To add e-liquid, a user must disassemble the base, which is inconvenient and might easily lead to loss of the liquid.

SUMMARY OF THE INVENTION

An object of the invention is to provide an electronic cigarette atomizer where the e-liquid will neither be easily aspirated into a user's mouth nor leak out, while maintaining convenient e-liquid filling. To achieve the objects of the invention, the present invention includes an electronic cigarette atomizer which includes a holder (7) connected to a base (19). The holder (7) is coated with a transparent tube (10). The upper and lower ends of the holder (7) are connected with the upper and lower ends of the transparent tube (10) hermetically. The air intake tube (11) to prevent the e-liquid from leaking out covers the upper half of the holder (7). The internal surface of the nozzle base (5) is connected to the outer surface of the exhaust tube (9). The internal surface of the holder (7) is connected with the outer surface of the nozzle base (5). The internal surface of the air intake tube (11) is connected with the outer surface of the nozzle base (5). There are air intake holes in the upper end of the holder (7). In the lower end of the nozzle base (5) there is a groove which is connected to the air intake holes. An air flow control valve (4) is set in a side of the outer surface of the holder (7). The nozzle base (5) is covered with a lid (3). An e-liquid fill hole (2) is set in the upper end of the air intake tube (11). A rubber column is plugged in the e-liquid fill hole (2). An end of the exhaust tube (9) is connected with a nozzle (1) which is set on the nozzle base (5) while the other end of the exhaust tube (9) is inserted into an atomization device. E-liquid is easy to refill but will neither be easily aspirated into one's mouth nor leak out.
Preferably, the above-mentioned atomization device includes parts as listed below. In an atomizing chamber (12), there is a cathode base of the heating wire (14), anode base of the heating wire (15), and heating wire (22) set between the cathode base of the heating wire (14) and the anode base of the heating wire (15). The first positive pole contact bar (18) is connected to the heating wire (15). The cathode base of the heating wire (14) is connected to the base (19). The first positive pole contact bar (18) is set in the base (19) mentioned above and the outer surface of the first positive pole contact bar (18) is coated with the first insulator (17). Additionally, the above-mentioned electronic cigarette atomizer also includes parts as listed below. The second positive pole contact bar (20) is connected to the first positive contact bar (18); the second positive pole contact bar (20) and the second insulator (21) are set in the lower part of the base (19). The second positive pole contact bar (20) is wrapped by the second insulator (21).
The air intake tube and the exhaust tube are independent of each other. An exhaust tube set in the nozzle is coated or lined with an air intake tube. The inter-space between the air intake tube and the exhaust tube is named the intake passage. When the vapor is inhaled, the air will enter the atomizing chamber through the air intake holes at the top of the chamber and the vapor atomized from the e-liquid will form an exhaust passage when the e-liquid goes through the exhaust holes at the top of the chamber and the nozzle. As both the air intake tube and the exhaust tube are set at the top of the tapered atomizing chamber, so the e-liquid will not be aspirated into a user's mouth easily. In addition, as the bottom of the atomizing chamber is completely sealed, the e-liquid will not leak out to the surface of the atomizer. With an independent e-liquid fill hole, it is very convenient to add e-liquid.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As shown in FIG. 1 and FIG. 2, the current embodiment of the invention includes: holder 7 and base 19. Preferably they can be better fixed together by thread. The holder (7) is coated with a transparent tube (10). The upper and lower ends of the holder (7) are connected with the upper and lower ends of the transparent tube (10) hermetically. The air intake tube (11) prevents the e-liquid from leaking out and covers the upper half of the holder (7). The internal surface of the nozzle base (5) is connected to the outer surface of the exhaust tube (9). The internal surface of the holder (7) is connected with the outer surface of the nozzle base (5). The internal surface of the air intake tube (11) is connected with the outer surface of the nozzle base (5). There are air intake holes in the upper end of the holder (7). In the lower end of the nozzle base (5) there is a groove which is connected to the air intake holes. An air flow control valve (4) is set in a side of the outer surface of the holder (7). The nozzle base (5) is covered with a lid (3). An e-liquid fill hole (2) is set in the upper end of the air intake tube (11). A rubber column is plugged in the e-liquid fill hole (2). An end of the exhaust tube (9) is connected with a nozzle (1) which is set on the nozzle base (5) while the other end of the exhaust tube (9) is inserted into an atomization device. The holder (7), exhaust tube (9), air intake tube (11) and the atomization device are all set within the transparent tube (10).
In the more specific embodiment, the above-mentioned atomization device includes the parts as below: in an atomizing chamber (12), there are a cathode base of the heating wire (14), anode base of the heating wire (15), and heating wire (22) set between the cathode base of the heating wire (14) and the anode base of the heating wire (15). The first positive pole contact bar (18) is connected to the heating wire (15). The cathode base of the heating wire (14) is connected to the base (19). The first positive pole contact bar (18) is set in the base (19) mentioned above. The outer surface of the first positive pole contact bar (18) is coated with the first insulator (17). The second rubber gasket 13 is set between the atomizing chamber 12 and the air intake tube 11 as a seal.
In other embodiments which are developed on the basis of the above ones, the electronic cigarette atomizer also includes parts as described below. A second positive pole contact bar (20) is connected to a first positive pole contact bar (18). The second positive pole contact bar (20) and the second insulator (21) are set in the lower part of the base (19). The second positive pole contact bar is enclosed such as by being wrapped by the second insulator (21). Two first rubber gaskets (8) are set in both the upper and the lower ends of the holder (7). The first rubber gaskets (8) mentioned above and the transparent tube (10) are joined together tight. The air flow control valve (4) can control the intake volume. The lid (3) can be twisted into the outer surface of the nozzle base (5). The modular parts below could be dismantled or replaced easily including the atomizing chamber (12), second rubber gasket (13), anode base of the heating wire (15), cathode base of the heating wire (14), heating wire (22), first positive pole contact bar (18) and first insulator (17).
The outside rubber gasket (13) of the air intake tube (11) and the outer surface of the air intake tube (11) form a tight fit so that the e-liquid does not leak out into the atomizing chamber (12). An independent e-liquid fill hole is designed to ensure a convenient e-liquid filling and to reduce waste of e-liquid. The dual-tube structure can reduce discomfort felt in a user's mouth and can solve the problem of leaking from the bottom of the electronic cigarette. The user follows an inhaling process as described hereinafter. Inhaling from the nozzle (1) causes the outer air to enter the air flow control valve (4), and then enter the atomizing chamber (12) through the inter-space gap between the air intake tube (11) and the exhaust tube (9). Then the vapor from the atomizing chamber (12) enters the mouth through the exhaust tube (9) and the nozzle (1). In the meantime, the atomizer should be charged with an external power source so that the heating wire (22) can vaporize the e-liquid with electricity. This electronic cigarette atomizer can prevent e-liquid from leaking out because the following parts are in a complete sealing condition including: the first insulator (17) toward the bottom, a first positive pole contact bar (18), base (19), second positive pole contact bar (20) and second insulator (21). Even if there is a little e-liquid that leaks out into the air intake tube (11), it will be taken back to the atomizing chamber (12) when the vapor is being inhaled, so the e-liquid will not leak out into the air flow control valve. The tapered inner space of the atomizing chamber makes it difficult for the e-liquid to flow back into the air intake tube (11) or the exhaust tube (9). The e-liquid fill hole (2) is set at the top of the air intake tube (11) to make it easy to add e-liquid.
The embodiment of this electronic cigarette atomizer offered in the invention has been introduced in detail above and a person of ordinary skill in the art could make changes to this specific mode of carrying out or its scope of application according to the idea of this embodiment of the invention. Accordingly, this specification is not a limitation to the scope of the claims of the invention defined below.
