Background Art

The electronic atomizer device is an electronic product that imitates cigarettes. It can convert smoke liquid into mist, giving the user a similar feeling to smoking when inhaling, achieving "puffing out smoke". Due to the similar taste and convenience of smoking as cigarettes, the electronic atomizer device has been rapidly promoted and used.

The electronic atomization device consists of two parts: an atomizer and a battery host. The atomizer is the smoke generating part of the electronic atomization device, and the battery host is the control center and power supply part of the electronic atomization device. When using the electronic atomization device, inhaling air at the nozzle of the atomizer can create airflow inside the electronic atomization device, triggering the pneumatic switch to open, thereby energizing the battery host and the atomizer. After the battery host and the atomizer are energized, the heating element installed in the atomizer can heat up the high-temperature atomized smoke oil, so that the smoke oil forms an aerosol at high temperature and flows to the nozzle for the user to inhale.

Technical issues

Usually, the atomizer and the battery host are arranged in an upper and lower structure, the heating element arranged in the atomizer is arranged close to the bottom of the atomizer, the start switch is arranged at the end where the battery host and the atomizer contact, and the pneumatic switch is far away from the suction nozzle of the atomizer; even if the atomizer and the battery host are arranged in a left-right structure, because the heating element arranged in the atomizer is arranged close to the bottom of the atomizer, and the pneumatic switch is arranged in the battery host and close to the heating element, the pneumatic switch is also far away from the suction nozzle of the atomizer.

The high-temperature smoke is evenly mixed with the cold air in the atomization channel and is inhaled by the user through the smoke channel 1442 and the smoke outlet 1422. The user will inhale the taste of the hotter smoke hitting the oral cavity, and the inhalation taste is good.

The smoke channel 1442 and the trigger channel 1444 are independent of each other, and a smoke outlet 1422 and a trigger outlet 1424 are provided separately, which can completely isolate the smoke channel 1442 and the trigger channel 1444, and prevent the volatile substances after the high-temperature atomization of the smoke oil from entering the pneumatic switch 32 through the trigger channel 1444, and cannot damage the pneumatic switch 32, which is beneficial to improving the smoking taste and extending the service life.

The atomizer 20 includes a shell 21, a sealing base 22, a sealing end cover 23, an atomizing assembly 24 and a partition tube 25. The sealing base 22 and the sealing end cover 23 are respectively arranged at the two ends of the shell 21. The partition tube 25 is arranged in the shell 21, and the two ends of the partition tube 25 are respectively fixed to the sealing base 22 and the sealing end cover 23. The sealing base 22 and the sealing end cover 23 cooperate with the partition tube 25 to divide the interior of the shell 21 into an oil storage chamber 26 and an atomizing chamber 27; the atomizing assembly 24 is arranged in the atomizing chamber 27, and the partition tube 25 is provided with an oil guide hole 252.

The sealing base 22 and the sealing end cover 23 can both be components made of silicone material. On the one hand, the elastic characteristics of the silicone material can play a sealing role to prevent the smoke oil in the oil storage chamber 26 from leaking out. On the other hand, the sealing base 22 and the sealing end cover 23 made of silicone material have a certain thickness, and their hardness can support the structure inside the shell 21.

In this embodiment, the sealing end cover 23 extends inside the housing 10 toward the battery host 30 until it contacts the inner wall of the housing 10, and the sealing end cover 23 is provided with a receiving groove 232 connected to the trigger channel 1444, and the pneumatic switch 32 is received in the receiving groove 232, and the pneumatic switch 32 is connected to the trigger channel 1444. That is, the entire end face of the sealing end cover 23 at the top of the oil storage chamber 26 contacts the inner wall of the housing 10, maintaining good sealing and fixing performance between the sealing end cover 23 and the housing 10, and the sealing end cover 23 is close to the suction nozzle 142, and the receiving groove 232 for accommodating the pneumatic switch 32 is close to the trigger port 1424 of the suction nozzle 142, so that when inhaling at the suction nozzle 142, the negative pressure of the airflow can quickly reach the pneumatic switch 32 through the trigger port 1424 and the trigger channel 1444, triggering the pneumatic switch 32 to turn on the electronic atomization device, and the triggering is sensitive. After the pneumatic switch 32 is turned on, the heating element is quickly energized and heated, atomizing the tobacco oil into high-temperature smoke. At the same time, the high-temperature smoke is evenly mixed with the room-temperature air inhaled from the outside into the suction nozzle 142 in the atomization chamber 27, so that the smoke inhaled into the user's mouth is smoke with a uniform taste and moderate temperature, and the smoking taste is good.

In this embodiment, one end of the sealing end cover 23 is disposed on the housing 21, and the other end is against the inner wall of the housing 10. The trigger channel 1444 is disposed through the sealing end cover 23, and the trigger channel 1444 is connected to the trigger port 1424 and the receiving groove 232. That is, in order to facilitate the electrical connection between the pneumatic switch 32 and the battery host 30, the pneumatic switch 32 is disposed close to the battery host 30, so a through channel needs to be disposed on the sealing end cover 23 at one end of the pneumatic switch 32 close to the suction nozzle 142, so that the trigger channel 1444 is formed to communicate with the trigger port 1424.

In another embodiment, one end of the sealing end cover 23 is disposed on the housing 21, and the other end is against the inner wall of the housing 10. A through groove is provided at the end of the sealing end cover 23, and the through groove is against the inner wall of the housing 10 to form a trigger channel 1444, and the trigger channel 1444 is connected to the trigger port 1424 and the accommodating groove 232. That is, in order to facilitate the electrical connection between the pneumatic switch 32 and the battery host 30, the pneumatic switch 32 is disposed close to the battery host 30, and in order to facilitate the operation and production of the trigger channel 1444 on the sealing end cover 23, a through groove can be directly provided on the upper end surface of the sealing end cover 23, and when the through groove is against the inner wall of the housing 10, the through groove and the inner wall of the housing 10 jointly form a trigger channel 1444 for airflow circulation, and when sucking at the suction nozzle 142, negative pressure can be formed at the pneumatic switch 32 through the trigger port 1424 and the trigger channel 1444, triggering the pneumatic switch 32 to open.

In this embodiment, the housing 10 includes a shell body 12 and a nozzle 142 cover 14 matched with the shell body 12, the nozzle 142 is arranged on the nozzle 142 cover 14, a limiting structure 146 connected with the nozzle 142 is extended from the nozzle 142 along the inside of the nozzle 142 cover 14, and the sealing end cover 23 is fixed around the limiting structure 146, and the nozzle 142 is connected with the atomization chamber 27 through the limiting structure 146. That is, during installation, the nozzle 142 cover 14 can be removed from the shell body 12, and the sealing end cover 23 can be fixed around the limiting structure 146, so that the top of the sealing end cover 23 fits with the inner wall of the nozzle 142 cover 14; at the same time, because the limiting structure 146 is a tubular structure extending from the nozzle 142 along the inside of the nozzle 142 cover 14, the nozzle 142 can directly pass through the bottom of the limiting structure 146 and communicate with the structure below the limiting structure 146. After the atomizer 20 and the battery host 30 are assembled, they are integrally mounted in the shell body 12 , and then the nozzle 142 cover 14 with the sealing end cover 23 installed is fixedly mounted on the shell body 12 .

Among them, the limiting structure 146 is provided with a liquid collecting tank 1462 at the end near the oil storage chamber 26, and a liquid collecting hole 1464 is opened on the wall of the limiting structure 146, and the liquid collecting hole 1464 is connected with the liquid collecting tank 1462. Specifically, the cross-section of the limiting structure 146 is a symmetrically arranged "乚" shape, and the liquid collecting tank 1462 is located at the bottom of the "乚" shape. When smoking the electronic atomization device, a small amount of condensate will be formed due to the contact between the low-temperature inner wall of the atomization chamber 27 and the high-temperature smoke formed during heating. When smoking, the condensate flows to the liquid collecting tank 1462 through the liquid collecting hole 1464 on the wall of the limiting structure 146, and is collected by the liquid collecting tank 1462, which can prevent the condensate from being sucked into the user's mouth, which is conducive to improving the smoking taste.

Furthermore, absorbent cotton is provided in the liquid collecting groove 1462, and the absorbent cotton absorbs the condensed liquid, turning the flowable liquid into non-flowable liquid, and can also prevent the condensed liquid from being sucked into the user's mouth, further improving the sucking taste.

The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
