[0026] This utility model is an electronic cigarette with a bottom-mounted direct air passage. For ease of description, as follows: Figure 1 As shown, the mouthpiece section 11 of the electronic cigarette of this utility model is placed vertically with the mouth facing upward. If there are descriptions of the various components of the electronic cigarette in this article such as "upper, lower, upper part, lower part, bottom, upper end, lower end, bottom end, above, below, bottom surface, upward, downward, horizontal, vertical", they all refer to the positional relationship of the components when the electronic cigarette is placed vertically with the mouth facing upward.
[0027] Example
[0028] like Figure 1 As shown, the present invention is an electronic cigarette with a bottom straight air passage, including an atomizer 1 and a power supply component 2.
[0029] like Figures 1-3 As shown, the atomizer 1 includes a mouthpiece section 11 and an insertion section 12 at the other end of the mouthpiece section. The mouthpiece section 11 has a smoke inlet 110 at its end, and the insertion section 12 has an air inlet 120 at its end. A smoke channel 10 is provided between the air inlet 120 and the smoke inlet 110. The smoke channel 10 includes an atomizing chamber 100. The atomizer has a liquid storage chamber 14 and an atomizing unit 13. After being powered on, the atomizing unit 13 heats and evaporates the atomizing liquid stored in the liquid storage chamber 14 into smoke, which is then dispersed into the atomizing chamber 100. The atomizing chamber 100 is a part of the smoke channel 10. Figure 2The continuous arrows in the smoke channel 10 indicate the airflow direction and path of the smoke entering and exiting through the main air intake duct 26 when the electronic cigarette is working.
[0030] like Figures 4-5 As shown, the power supply component 2 has a tubular power supply housing 23. The power supply component 2 includes a battery section 21 and a receiving section 22. The battery section 21 and the receiving section 22 share a common power supply housing 23. The battery section 21 contains a battery cell 72. The receiving section 22 contains a receiving cavity 220 formed by the power supply housing 23 and one end of the battery section 21. The bottom of the receiving cavity 220 is provided with a bottom wall 221 that fits tightly against the inner wall of the power supply housing 23. The insertion section 12 is detachably inserted into the receiving section 22. That is, after the insertion section 12 and the receiving section 22 are inserted, they form an electronic cigarette unit. However, they can be easily separated by pulling them by hand. A sealing ring 24 with an upward protrusion is provided on the bottom wall 221 of the receiving cavity 220 near the center. The main air supply port 25 is provided on the bottom wall of the receiving cavity 220 within the sealing ring 24. The battery section 21 has a main air intake duct 26 that runs through the bottom and directly connects to the main air supply port 25. When the atomizer is inserted into the receiving cavity 220, the protruding sealing ring 24 can seal against the end of the insertion section 12. The air intake port 120 is located inside the sealing ring 24 and communicates with the main air supply port 120. Since the sealing ring 24 abuts against the end of the insertion section 12 and the bottom wall 221 of the receiving cavity, a sealed space is formed between the main air supply port 25 and the air inlet 120. The air outside the sealing ring 24 will not flow with the sealed space inside the sealing ring 24. That is, when the user inhales, the air inhaled from the air inlet 120 will not flow through the air passage formed by the gap between the battery section 21 and the receiving section 22, but can only enter the sealing ring 24 through the main air supply port 25 from the main air inlet 26, and then enter the air inlet 120. Figure 5 The continuous arrows within the main air intake duct 26 indicate the direction and path of airflow entering through the main air intake duct 26 when the electronic cigarette is in operation.
[0031] The electronic cigarette has the advantages that the main air inlet is arranged on the bottom wall of the accommodating cavity of the power component, the main air inlet is in communication with the outside air inlet arranged on the bottom of the power component, the user's hand does not block the outside air inlet when the user holds the electronic cigarette, the user can easily inhale the electronic cigarette smoke, and the water mist in the backflow caused by the user stopping smoking can be directly discharged to the outside air, so that the water mist is not easy to condense on the bottom of the atomizer and the bottom of the power component accommodating cavity, the electrode column or the electrode contact is prevented from being corroded, and the water drops are prevented from being brought out when the user plugs in or unplugs the electronic cigarette atomizer.
[0032] In the embodiment, the main air inlet is composed of a straight-through sealed pipeline, the sealed pipeline refers to a pipe-shaped channel with sealed inside, and only the two ends have inlets and outlets, and specifically, for example, the sealed pipeline can be composed of a hollow pipe. The main air inlet is composed of a sealed pipeline, that is, the middle path of the sealed pipeline is completely isolated from the other components except the port portions of the upper and lower ends, air cannot leak inwards or outwards, the air entering when the user smokes enters completely from the outside air inlet on the bottom, the air is prevented from flowing tortuously in the narrow space between the battery support and the scheme plate, and the air entering resistance is reduced. Meanwhile, when the user just stops smoking, the smoke in the atomizer flows back to the main air inlet from the smoke channel, the backflowing smoke can carry small liquid drops which have not been completely atomized or condensed, if the main air inlet is not a sealed air channel, the backflowing smoke can pass between the battery support and the scheme plate, the small liquid drops in the smoke condense on the scheme plate, and the liquid drops can corrode and damage the circuit and electronic elements in the scheme plate after a long time, so that the circuit and electronic elements are damaged or even the electronic cigarette is damaged.
[0033] As shown in Figure 4 , Figure 8 , the bottom wall of the accommodating cavity is provided with an auxiliary air inlet in the sealing ring, the battery section is provided with an auxiliary air inlet in communication with the auxiliary air inlet, and the auxiliary air inlet is in communication with the air flow sensor arranged in the battery section. When the user smokes, the negative pressure or air flow generated in the smoke channel can be conducted to the auxiliary air inlet at the same time, the air flow sensor in communication with the auxiliary air inlet can sense the negative pressure or air flow, so as to trigger the electronic cigarette atomizer to work and generate smoke.

When the insertion section 12 is inserted into the accommodating section 22, the electrode column 28 is in contact with the electric contact 121, thereby physically connecting the power supply circuit in the power supply part 2 with the circuit of the atomizing unit 13 in the atomizer 1. The electrode column 28 can be a telescopic or elastic electrode column so as to be in close contact with the electric contact 121. The electric contact 121 can be a planar electric contact.

The end of the insertion section 12 of the atomizer is provided with a ferromagnetic bottom shell 122 which is in magnetic connection with the magnet 29. The ferromagnetic bottom shell 122 is made of ferromagnetic material which has the property of being magnetically attracted to the magnet. The ferromagnetic bottom shell 122 can be a stainless steel bottom shell or an iron shell.

The main air inlet 25 passes through the sealing sleeve 3 upwardly and the outer periphery of the main air inlet 25 is sealed by the sealing sleeve 3. The sealing ring 24 is integrally formed on the upper portion of the sealing sleeve 3. The auxiliary air inlets 27 and the electrode column 28 pass through the sealing sleeve 3 upwardly and the outer periphery thereof is sealed by the sealing sleeve 3. In this way, a closed space is formed within the sealing ring 24. Only the air inlet 120 is in communication with the main air inlet 25 and the auxiliary air inlets 27.
