Description

Electronic cigarette with filtering function

The present invention relates to an electronic cigarette, and in particular, to an electronic cigarette that can filter the smoke exhaled by the user after smoking.

In recent years, e-cigarette products have become popular, and more and more people are using e-cigarettes to replace traditional cigarettes. Electronic cigarettes, also known as electronic atomizers, are electronic products that imitate cigarettes. E-cigarette is a battery-powered atomizer that heats the e-liquid (commonly known as e-liquid, E-liquid, E-juice, etc.) in the oil tank to generate vapor for users to ingest.

In some existing electronic cigarette products, the electronic cigarette includes an activation device (such as a button switch) to activate the atomizer to heat the electronic liquid and generate vapor for the user to inhale. However, the activation device has a limit on the number of times it can be used. When the user frequently uses the activation device, the activation device may have poor contact and fail to activate the atomizer. Furthermore, if the starting device is short-circuited due to poor contact, the electronic cigarette is more likely to explode.

帶電子煙以及二手煙過濾器，不僅提高成本並且降低使用效率。 On the other hand, after the vapor produced by the electronic cigarette is inhaled by the user, the smoke exhaled by the user will still become second-hand smoke. Although the amount of secondhand smoke produced may be lower than that of traditional cigarettes, it can still cause harm to others. The existing solutions to second-hand smoke include planning an isolated space (such as a smoking area), using air purifiers, and using second-hand smoke filters. However, the isolated space only limits the spread of second-hand smoke, but it still cannot filter and eliminate second-hand smoke; the air purifier can only clean second-hand smoke in a specific area; and the second-hand smoke filter is another product, when the user uses an e-cigarette After inhaling the vapor, the user needs to breathe the smoke into the second-hand smoke filter for filtering. Therefore, the user must also

With electronic cigarettes and second-hand smoke filters, it not only increases the cost but also reduces the efficiency of use.

In view of this, the present invention proposes an electronic cigarette with a filtering function to solve the problems of the prior art. According to a specific embodiment of the present invention, an electronic cigarette with a filtering function is used to filter the smoke generated by the user after smoking. An electronic cigarette with filtering function includes a body, a pressure sensor, a switching component, and a solenoid valve. The body has an accommodating space, a first channel and a second channel. The first channel and the second channel are respectively connected to the vacant space. The pressure sensor is arranged in the main body and used to detect the pressure value of the accommodating space. The switching component is movably arranged in the main body and used for shielding one of the first channel and the second channel. The solenoid valve is coupled to the pressure sensor and the switching component, and the solenoid valve is prestored with a pressure threshold. When the pressure value is greater than the pressure threshold, the solenoid valve controls the switching component to shield the first passage, so that the smoke passes through the second passage.

Wherein, the electronic cigarette with filtering function further includes a filter element arranged in the second channel. The filter element is used to filter the smoke flowing through the second channel.

Further, the filter element is at least one of a fiber filter screen, an activated carbon filter screen, and a high efficiency filter screen.

Wherein, the main body includes a suction nozzle, and the suction nozzle includes a pipeline to communicate with the accommodating space, so that the user can spit smoke into the accommodating space through the suction nozzle.

Further, the pressure sensor is arranged on the inner wall of the pipeline of the suction nozzle.

Among them, the electronic cigarette with filtering function further includes an atomizing part arranged in the first In one channel. The atomizing component is used for generating inhalation gas to the accommodating space for the user to inhale.

Among them, the atomizing component is connected to the solenoid valve. When the pressure value detected by the pressure sensor is less than the pressure threshold value, the solenoid valve controls the switching component to shield the second passage, and the atomizing component generates inhalation gas.

Wherein, the body includes an exhaust port communicating with the second channel. The exhaust port is used to exhaust the filtered smoke to the outside environment.

Among them, the pressure threshold is atmospheric pressure.

In this specific embodiment, the first channel 111 and the second channel 112 are adjacently arranged on the left and right, and the accommodating space 110 is located above the first channel 111 and the second channel 112 and communicates with the first channel 111 and the second channel 112.

In this specific embodiment, the main body 11 includes a suction nozzle 115, and the suction nozzle 115 has a pipeline 1151 communicating with the accommodating space 110. In practice, the suction nozzle 115 can be integrally formed on the body 11 and can be a cylinder, but it is not limited to this. The shape of the suction nozzle 115 can also be a rectangular parallelepiped or designed according to requirements. The pipeline 1151 of the suction nozzle 115 may be a through hole to communicate with the external environment and the accommodating space 110. Therefore, when the user smokes or exhales, the user can respectively inhale the smoke in the accommodating space 110 through the mouthpiece 115 or spit the smoke into the accommodating space 110.

In this embodiment, the electronic cigarette 1 with filtering function includes a pressure sensor 12 disposed in the main body 11, and the pressure sensor 12 is used to detect the pressure value of the accommodating space 110. In practice, the pressure sensor 12 can be a gas pressure sensor, and can measure the gas pressure value of the accommodating space 110 according to the change in the air flow generated by the user smoking or exhaling smoke. The pressure sensor 12 can be arranged at any position on the inner wall of the main body 11. In this specific embodiment, the pressure sensor 12 is disposed at a position adjacent to the suction nozzle 115 to measure the pressure value of the accommodating space 110. The location of the pressure sensor 12 is not limited to this. In a specific embodiment, the pressure sensor 12 is provided on the inner wall of the pipe 1151 of the suction nozzle 115. In practice, when the user smokes or exhales through the mouthpiece 115, the pressure sensor 12 can quickly sense the airflow change in the pipeline 1151 and measure the pressure value of the accommodating space 110.

In this specific embodiment, the electronic cigarette 1 with filtering function includes a switching component 13 and a solenoid valve 14. The switching component 13 is movably disposed in the accommodating space 110, and the solenoid valve 14 is connected to the switching component 13 and coupled to the pressure sensor 12. The solenoid valve 14 can control the switching part 13 to shield the One channel 111 or second channel 112. In practice, the shape of the switching member 13 can correspond to the shape of the first channel 111 and the second channel 112 and can be arranged between the accommodating space 110 and the first channel 111 and the second channel 112. The solenoid valve 14 can be disposed on the baffle 117, and can control the switching member 13 to move in the left-right direction according to the detection result of the pressure sensor 12, thereby shielding the first channel 111 or the second channel 112. Please note that the setting position of the solenoid valve 14 and the movement direction of the control switching component 13 are not limited to this. When the solenoid valve 14 controls the switching member 13 to shield the first passage 111, the first passage 111 and the accommodating space 110 are not communicated, and the second passage 112 and the accommodating space 110 are communicated with each other. Similarly, when the solenoid valve 14 controls the switching member 13 to shield the second passage 112, the second passage 112 is not connected to the accommodating space 110, and the first passage 111 and the accommodating space 110 are in communication with each other.

Further, the solenoid valve 14 prestores a pressure threshold, and the solenoid valve 14 can control the switching component 13 to shield the first channel 111 or the second channel 112 according to the pressure measured by the pressure sensor 12 and the pressure threshold. The pressure threshold may be the pressure value when no gas flows in the accommodating space 110, that is, when the user is not using the electronic cigarette, the pressure measured in the accommodating space 110 is the pressure threshold. The pressure threshold can also be atmospheric pressure. In this embodiment, when the gas pressure measured by the pressure sensor 12 is greater than the pressure threshold, the solenoid valve 14 controls the switching component 13 to shield the first passage 111, and when the gas measured by the pressure sensor 12 When the pressure value is less than the pressure threshold, the solenoid valve 14 controls the switching component 13 to shield the second passage 112.

When the user smokes or exhales, the gas pressure in the accommodating space 110 of the main body 11 changes due to the flow of gas. At this time, the gas measured by the pressure sensor 12 arranged in the accommodating space 110 The pressure value also varies with the change of the gas pressure of the accommodating space 110. When the user exhales smoke to the accommodating space 110 of the main body 11 after smoking, the gas in the accommodating space 110 is additionally squeezed by the outside air, causing the gas pressure to be high and exceed the pressure threshold. At this time, the solenoid valve 14 According to the detection result of the pressure sensor 12, the switching component 13 is controlled to shield the first passage 111, and the smoke in the accommodating space 110 flows to the second passage 112.

Furthermore, the electronic cigarette 1 with a filtering function further includes a filter element 16 and the body 11 includes an exhaust port 119. The filter element 16 is disposed in the second passage 112, and the exhaust port communicates with the second passage 112. Furthermore, the filter element 16 is disposed between the accommodating space 110 and the exhaust port 119. When the smoke flows from the accommodating space 110 to the second passage 112, the smoke passes through the filter element 16 disposed in the second passage 112, and then the smoke is discharged into the external environment through the exhaust port 119. The filter element 16 may be an element with a gas purification function, such as a fiber filter, an activated carbon filter, and a high-efficiency particulate air (HEPA). Further, the filter element can also be at least one or a combination of a fiber filter, an activated carbon filter, and a high-efficiency filter. Therefore, the electronic cigarette 1 with filtering function of the present invention can automatically determine that the user is spitting out cigarettes, and guide and filter the second-hand smoke generated by the user after smoking, thereby improving safety.

On the other hand, when the user smokes, the gas in the accommodating space 110 is drawn to the outside and the gas pressure becomes smaller and smaller than the pressure threshold. At this time, the solenoid valve 14 controls the switching according to the detection result of the pressure sensor 12 The component 13 shields the second channel 112. Please refer to Figure 3. FIG. 3 is a simplified schematic diagram showing that the switching component 13 of FIG. 2 shields the second channel 112.

The atomizing component 17 is arranged in the first passage 111, and the air inlet 118 communicates with the first passage 111. Furthermore, the atomizing component 17 is disposed between the accommodating space 110 and the air inlet 118. The atomizing component 17 is used to generate inhalation gas to the accommodating space for the user to inhale. Furthermore, the atomizing component 17 is connected to the solenoid valve 14. When the solenoid valve 14 controls the switching component 13 to shield the second passage 112 according to the pressure value detected by the pressure sensor 12 being less than the pressure threshold value, the atomizing component 17 generates inhalation gas until the container is empty. The room 110 is for the user to inhale. The atomizing component 17 may include a motherboard, a battery, and an atomizer. The main board can be connected to the solenoid valve 14 and control the heating of the atomizer to generate inhalation gas. In practice, when the user smokes, the solenoid valve 14 controls the switching component 13 to shield the second passage, air is drawn into the first passage 111 from the air inlet 118, and the atomizing component 17 generates inhalation gas, and the air and inhalation gas are Flow to the accommodating space 110 for the user to inhale. Therefore, the electronic cigarette 1 with filtering function of the present invention has both smoking function and filtering function, and can automatically switch the smoking mode or filtering mode according to the gas pressure generated by the user smoking or spitting, which not only effectively reduces the cost but also improves the efficiency .

In addition, in this specific embodiment, when the pressure value measured by the pressure sensor 12 is equal to the pressure threshold value, the solenoid valve 14 controls the switching component 13 to shield the first passage 111. When the user is not using the electronic cigarette, that is, when there is no gas flow in the accommodating space 110 of the main body 11 so that the pressure does not change, the solenoid valve 14 controls the switching component 13 to shield the first passage 111. In practice, when the electronic cigarette 1 with filtering function of the present invention is not in the smoking mode or filtering mode, the solenoid valve 14 can be used to control the switching component 13 to shield the first passage 111 to prevent the atomizing component 17 located in the body 11 Start by mistake to improve safety.

FIG. 5 is a cross-sectional view of the electronic cigarette 2 with filtering function of FIG. 4 in a viewing angle. FIG. 6 is a cross-sectional view of the electronic cigarette 2 with filtering function of FIG. 4 from another perspective. The difference between this embodiment and the previous embodiments is that the shape of the body 21 of this embodiment is a cylinder, and the body 21 includes an annular baffle 217 disposed at the center of the bottom of the body 21. Further, the baffle 217 divides a part of the cavity into a first channel 211 and a second channel 212, and the baffle 217 The unseparated part of the cavity forms an accommodating space 210, as shown in FIGS. 5 and 6. The atomizing component 27 is disposed in the first channel 211, and the filter element 26 is disposed in the second channel 212 in a ring shape. Further, the shape of the switching member 23 is a ring structure, and the solenoid valve 24 can control the upward and downward movement of the switching member 23.
