Description

an electronic cigarette

technical field

The utility model relates to an electronic cigarette.

Background technique

At present, most electronic cigarettes on the market use resistance heating atomization technology, in addition to ultrasonic atomization technology, jet atomization technology, and induction atomization technology. The electronic cigarette structure of resistance heating atomization is relatively simple, but it needs compressed air or adsorption to squeeze out the smoke oil. Due to the sealing structure such as sealing rings used in many places in this structure, oil leakage or oil leakage is easy to cause blockage of the pipeline in the electronic cigarette ; Ultrasonic atomization technology, jet atomization technology, and induction atomization technology are expensive and difficult to implement. At present, there are electronic cigarettes that do not produce smoke on the market, which are difficult for consumers to accept.

Contents of the invention

The technical problem to be solved by the utility model is to provide an electronic cigarette with a simple structure and easy implementation to solve the problem that the existing electronic cigarette is prone to oil leakage or oil leakage, which leads to the blockage of the pipeline in the electronic cigarette. .

In order to solve the above technical problems, the technical solution adopted by the utility model is: an electronic cigarette, which is characterized in that it includes an oil storage device with contraction pressure, the oil storage device communicates with the smoke oil injection device, and the smoke oil A one-way valve is provided in the injection device; the bottom of the oil storage device communicates with the top of the smoke oil outlet channel, and a control valve is installed on the smoke oil outlet channel, and the bottom end of the smoke oil outlet channel is heated by the conduit and the heating device The cavity is connected; the power supply port of the heating device and the switch of the control valve are connected in series with the power supply to form a loop.

The oil storage device is made of rubber; or the oil storage device includes a hollow fixing device and an oil storage bag; the oil storage bag is fixed in the cavity of the fixing device, and the open end of the oil storage bag is connected to the The bottom of the cavity of the fixing device is connected, and the bottom of the cavity of the fixing device under the opening end of the oil storage bag is provided with an oil filling port and an oil outlet; the outer wall of the oil storage bag is in contact with the spring pressing device, and when the smoke oil is injected, The oil storage bag pushes the spring pressing device to both sides and opens; when the oil outlet is opened, the spring pressing device squeezes the oil storage bag to shrink; the smoke oil injection device is installed in the oil filling port; The top end of the smoke oil outlet channel is installed in the oil outlet. The oil storage device with shrinkage pressure can automatically squeeze out the e-liquid by its own shrinkage pressure, without sealing structures such as sealing rings, and has high reliability, which overcomes the defects of easy oil leakage or oil leakage of existing electronic cigarettes.

Compared with the prior art, the utility model has the following beneficial effects: the utility model is simple in structure, easy to implement, low in cost and strong in reliability, and overcomes the defect that the current electronic cigarette is prone to oil leakage or oil leakage due to its complicated structure.

Detailed ways

As shown in Figure 1, an embodiment of the present invention includes an oil storage device 1 with contraction pressure, the oil storage device 1 communicates with an e-liquid injection device 11, and a one-way valve 12 is provided in the e-liquid injection device 11 The bottom of the oil storage device 1 communicates with the top of the smoke oil outlet channel 2, a control valve 21 is installed in the smoke oil outlet channel 2, and the bottom end of the smoke oil outlet channel 2 passes through the conduit 3 and the heating chamber of the heating device 4 Communication; the power supply port of the heating device 4 and the switch of the control valve 21 are connected in series with the power supply 5 to form a loop.

When the storage device with shrinkage pressure is storing oil, the smoke oil is pressed into the device through the smoke oil injection device. The storage device with shrinkage pressure will gradually deform or expand with the injection of smoke oil. After stopping the oil injection, the one-way valve will (inward) will automatically close, forming an airtight space. When the button switch 22 of the control valve 21 is pressed, the valve of the control valve 21 will be opened, and the battery will automatically supply power to the heating device 4 at the same time, and the e-liquid will be squeezed into the heating device 4 through the e-liquid outlet channel 2 and the conduit 3, and the temperature will be raised and atomized. Produces smoke.

The storage device with shrinkage pressure can be an elastic rubber material, or a non-elastic material with an external extrusion device. The final requirement is to be able to automatically squeeze out the e-liquid.

The oil storage device of the present utility model can adopt the structural form as shown in Figure 2, and it comprises hollow fixing device 6 and oil storage bag 7; Said oil storage bag 7 is fixed in the cavity of described fixing device 6, so The opening end of the oil storage bag 7 is connected to the bottom of the cavity of the fixing device 6, and the bottom of the cavity of the fixing device 6 under the opening end of the oil storage bag 7 is provided with an oil filling port 8 and an oil outlet 9; The outer wall of the bag 7 is in contact with the spring pressing device 10. When the smoke oil 13 is injected, the oil storage bag 7 pushes the spring pressing device 10 to both sides and opens; when the oil outlet 9 is opened, the spring pressing device squeezes the The oil storage bag 7 shrinks; the e-liquid injection device 11 is installed in the oil filling port 8 ; the top end of the e-liquid outlet channel 2 is installed in the oil outlet 9 .
