Description

Atomizer for turning off oil and gas

Technical Field

The utility model relates to an atomizer of vapour fog generating device, in particular to can close the atomizer of oil and gas simultaneously.

Background

The currently used inhalation type vapor-fog generating device is generally a device for atomizing special liquid by electric heating, and the most used device is a product commonly called electronic cigarette. The product comprises an atomizer inside which an electrically heated atomizing assembly, called an atomizing core, is arranged.

The atomizing core of the electronic cigarette is generally fixedly arranged on a base in the atomizer, the upper end of the atomizing core is connected with the suction air flue, and the lower end of the atomizing core is connected with the air inlet channel and the double electrodes. The cavity between the outer side of the atomizing core and the atomizer shell is an oil storage bin for storing tobacco tar. The atomizing core is provided with three channels, one is a steam fog outlet and is used for connecting and sucking an air passage; one is an air inlet connected with the airflow inlet; the steam outlet and the air inlet are respectively positioned at the upper end and the lower end of the atomizing core and penetrate through the atomizing core. The other one is an oil inlet hole which is an opening on the side wall of the atomizing core. Because the air flow is smooth when smoking, the air inlet and the steam fog outlet are exposed in the air flow channel for a long time and communicated with the outside atmosphere, at the moment, the inside of the atomizing core is communicated with the tobacco tar inlet, and the tobacco tar in the oil storage bin can enter the atomizing core through the oil inlet hole and then leak from the steam fog outlet or the air inlet. Due to the necessary ventilation of the atomizing core and the atomizer, the phenomenon of oil leakage is essentially unavoidable.

In view of the above problems, various atomizer oil leakage prevention structures have appeared.

A typical one is a structure for preventing oil leakage by rotation. The structure is a structure for rotationally sealing the oil inlet hole of the atomizing core, the outer side of the atomizing core is sleeved with a cylindrical cover body, the cover body and the oil inlet hole identical to the atomizing core can be aligned, staggered or in a state between the atomizing core oil inlet hole and the cover body oil inlet hole respectively by means of rotation of the cover body. The function of closing and opening the oil inlet channel is realized, and oil leakage is avoided. However, this structure still has drawbacks: (1) the rotary cover body needs to be connected with an external rotating device to control the rotation of the cover body, so that the structure is complex, the rotary cover body is positioned in the oil storage bin, the external control device needs to be arranged outside the atomizer, and a complex sealing device is needed to prevent oil leakage in rotation. (2) The shell of the atomizing core and the rotary cover body are both of metal cylinder structures, and mutual rotation needs to be guaranteed, so that the atomizing core can be realized only by arranging a certain gap. And the sealing device is difficult to be arranged between the surfaces of the inner and outer cylindrical metal walls, so that the sealing effect is poor, the tobacco tar is liquid and cannot enter without holes, and as long as a small gap exists, the oil leakage phenomenon still can be caused, and the problem of oil leakage cannot be fundamentally solved.

The other type is a structure of sliding oil locking, a sliding sleeve is arranged outside the atomizing core, the atomizing core is covered by the sleeve, an oil inlet hole is not formed in the sliding sleeve, when the atomizing core oil inlet hole is covered by the sliding sleeve in a sliding mode, the atomizing core oil inlet channel is blocked, and the atomizing core oil inlet and the atomizing core oil leakage are avoided. But still have some tobacco tar to remain inside atomizing core after atomizing core inlet port is sheltered from, still have a little tobacco tar to leak.

In addition, the above structure is generally considered from the point that the atomizing core closes the oil inlet hole, and the leakage outlet of the smoke oil is also an important problem. Such as the air inlet of the atomizer and the suction of the vapor mist out of the air passage, which is a smoke oil leakage outlet, blocking the smoke oil leakage outlet is also a concern. Therefore, the adjusting rings are arranged at the air inlets of the atomizers, the adjusting rings can control the opening and closing of the air inlets, the air inlet adjusting function can be achieved, and a certain oil leakage preventing effect can be achieved. However, in the current electronic cigarette products, an oil leakage prevention device is rarely arranged on the suction air channel. And the suction air flue is direct and the person's of suckling oral cavity contact as the smog export, more needs prevent that the tobacco tar from entering into the smog export and influencing the smoking sensation, also need set up the device of closing the suction air flue simultaneously, avoids inside the filth drops to atomizing core.

In summary, the atomizers with the oil-closing structure in the electronic cigarette in the prior art are really many, but there is no atomizer structure capable of simultaneously closing air and oil. Moreover, as long as the electronic cigarette suction air channel is open, the electronic cigarette cannot be completely polluted by the electronic cigarette oil, and the dirty dirt cannot be prevented from falling into the atomizing core from the cigarette holder, and when the dirty dirt enters the atomizing core, the dirty dirt is heated or even ignited when the cigarette is heated and smoked, so that the cigarette smoking port feels a great influence.

In view of the above, the present inventors have devised an atomizer having a simultaneous fuel cut and gas cut off, which shuts off a smoke passage and an air flow passage when no smoking is made. The purpose of avoiding oil leakage and dirty smoke outlet is realized.

When the suction air channel assembly is located at the second position, the air closing device closes the steam fog outlet of the atomizing core assembly, and the oil closing device cuts off the tobacco tar channel; when the suction air channel assembly is located at the first position, the air closing device opens the steam fog outlet of the atomizing core assembly, and the oil closing device opens the tobacco tar channel.

The specific implementation process is as follows: the conical valve 13 of the present embodiment is fixed inside the suction air duct 14 by interference fit, and the oil control ring 141 is integrally provided at the bottom end of the suction air duct 14. Thus, the axial position between the conical valve 13 and the oil control ring 141 is fixed, and the axial distance is also fixed. The axial distance between the conical valve 13 and the oil control ring 141 needs to be accurately calculated in advance during manufacturing, so that the conical valve 13 and the oil control ring 141 can be linked, and the function of simultaneously blocking the smoke oil channel 241 and the suction air channel 14 can be realized during the linkage process. That is, while the oil control ring 141 abuts against the base seal 24, the sealing ring 231 of the conical valve 13 abuts against the sealing ring, and the oil and gas closing functions are simultaneously realized. The sealing gasket can be made of soft material, such as silica gel, etc., and the soft sealing gaskets 24 and 231 are provided so that the compressibility of the soft material can compensate for assembly errors when a small assembly error occurs, and a good sealing effect is also achieved.

As shown in fig. 4, it is a sectional structure view of the suction duct 14 at the first position in the present embodiment. At this time, the electronic cigarette is in a smoking state, the suction air passage 14 is lifted to a position close to the upper end of the atomizer, the oil control ring 141 is also lifted to a position close to the atomizing core 23 in a linkage manner, the oil control ring 141 is separated from the sealing gasket 24 of the base at this time, the oil inlet channel 241 is opened, and the tobacco tar can enter the atomizing core 23 at this time. Meanwhile, the conical valve 13 positioned on the inner side of the suction air channel 14 is lifted, the conical valve 13 is separated from the sealing gasket 231 of the steam fog outlet of the atomizing core, the steam fog outlet at the upper end of the atomizing core is opened, atomized smoke can pass through the steam fog outlet and wind the air vent hole 132 at the outer edge of the conical valve 13, and the atomized smoke can be sucked out through the suction air channel 14, so that the function of smoking is realized.

As shown in fig. 5, is a sectional structure in which the suction gas channel 14 is located at the second position in the present embodiment. The electronic cigarette is in a state of closing oil and gas, namely a state of not smoking. At this time, the suction air duct 14 is pressed down, and the oil control ring 141 abuts against the base gasket 24 along with the pressing down of the suction air duct 14 to shield the oil inlet channel 241, so as to avoid or reduce oil leakage. Meanwhile, the cone valve 13 is pressed down to tightly press the sealing gasket 231 arranged at the steam fog outlet of the atomizing core, so as to cut off the suction air channel 14. So as to prevent the smoke oil leaked from the atomizing core 23 from flowing out of the suction air passage 14, and simultaneously, the smoke oil can block the passage of external dirt into the atomizing core 23.

As shown in fig. 6 and 7, as to how to realize the axial sliding of the suction air passage 14 on the periphery of the atomizing core 23 in the present embodiment, it can be realized by providing a snap-fit device between the fixed cap 21 and the movable cap 12.

The clamping device between the fixed cover 21 and the movable cover 12 is to arrange a snap ring 123 on the movable cover 12, the snap ring 123 is fixedly connected with the movable cover 12, and an inward protruding clamping block 122 is arranged on the snap ring 123. Meanwhile, the outer edge of the fixed cover 21 is provided with an annular clamping groove, which is an upper annular clamping groove 211 and a lower annular clamping groove 212, and the clamping block 122 can slide in the upper annular clamping groove 211 and the lower annular clamping groove 212, so that the relative rotation between the movable cover 12 and the fixed cover 21 is realized. In addition, a transfer groove 216 with the same depth is provided between the upper and lower annular locking grooves, so that the position of the latch 122 can be transferred between the upper and lower annular locking grooves through the transfer groove 216. And in the process of conversion between the upper annular clamping groove and the lower annular clamping groove, the sliding conversion between the movable sleeve I and the fixed sleeve II is realized, and the conversion from the first position to the second position of the suction air passage is realized. When the fixture block 122 is positioned in the upper annular clamping groove 211, the suction air channel 14 is in the first position and is in a smoking state; when the latch 122 is located in the lower annular groove 212, the suction air passage 14 is located at the second position and is in a non-smoking state.

In order to lock the electronic cigarette atomizer in two different states of a smoking state or an idle state, malfunction cannot occur. The mutual rotation angle of the movable sleeve member I and the fixed sleeve member II needs to be limited, infinite rotation is avoided, the upper and lower annular clamping grooves 211 and 212 can be set to be in a semi-ring state, and only semi-ring rotation is carried out.

As shown in fig. 8, the latch 122 on the snap ring 123 of the movable cover is a latch with a middle opening 1221, and the latching surface of the elastic latch 210 is set to be an inclined surface or an arc surface, when the latch 122 rotates to the position of the elastic latch 210, the latch 210 can continue to rotate to the latch 210 through the elastic action of the elastic latch 210 and the latch 210 is latched in the opening 1221, so as to form a locking state, and at this time, the movable sleeve i and the fixed sleeve ii can be locked and positioned in one state, and cannot easily rotate or slide. When the state needs to be switched, the movable sleeve is rotated forcibly, the clamping block 122 can be separated from the elastic clamping block 210 to unlock the locking part by overcoming the elastic force of the spring 219, then the clamping block 122 is rotated to the switching groove 216, then the switching groove is switched to another annular clamping groove, and then the clamping block is rotated back to be positioned again, so that the state switching and the locking are realized. In order to ensure that the latch 122 does not rotate beyond the predetermined position, a fixed latch 218 is disposed on one side of the elastic latch 210, and the fixed latch 218 does not have an inclined surface or an arc surface of the elastic latch 210, so that the latch 122 cannot pass over the fixed latch and rotate to the latch position.

In the present embodiment, since the oil hole is not suitable to be formed because of the axially sliding arrangement between the cover surface portion of the fixed cover 21 and the movable cover 12, the oil hole 221 needs to be formed in the side wall of the fixed cover 21. In the state shown in fig. 6 and 7, an oil filler hole closure iii is provided for opening and closing the oil filler hole 221, and the oil filler hole closure iii is sleeved at the oil filler hole, sealed with the oil filler hole 221 by a seal ring, and axially slidable.

The oil filling hole sealing structure is characterized in that a clamping ring is arranged on the inner wall of the oil filling hole sealing structure III, the clamping ring can be clamped by a clamping piece 215 and positioned in the axial direction, a return spring 213 is arranged on the clamping piece 215, an inclined surface 214 is arranged on the upper side of the clamping piece 215, the inclined surface 214 is in contact with the edge of the outer ring part of the movable cover 12, when the movable cover 12 is pressed downwards and locked at the second position, the clamping piece 215 is compressed through the inclined surface 214, the oil filling hole sealing structure III can be unlocked, and the oil filling hole sealing structure III can move axially and open the oil filling hole 221 to fill oil. When the movable cover 12 is in the first position in the smoking state, the clamping piece 215 extends out under the elastic force of the spring to clamp the oil filler hole seal III, and the oil filler hole cannot be opened.

Example 2: referring to fig. 9, this embodiment is an improved embodiment based on embodiment 1, and in embodiment 1, the conical valve 13 is of a fixed structure, so the axial distance between the conical valve 13 and the oil control ring 141 is fixed, and only by designing the fixed position in advance and then accurately installing and positioning, the functions of oil locking and air stopping can be realized by the linkage of the conical valve 13 and the oil control ring 141, and a small assembly error is realized by plastic deformation of the soft gasket, so the effect is slightly poor. The improvement of the embodiment is that the conical valve 13 is elastically arranged on the inner side of the suction air channel 14, so that the conical valve 13 can elastically slide within a certain axial distance, and further the steam and mist outlet of the atomizing core can be elastically blocked.

The structure is shown in fig. 9, the edge of the cone valve 13 is clamped between the clamping platform 142 and the clamping ring 143 on the inner side of the suction air channel 14, so that the cone valve 13 has a certain moving space in the suction air channel 14, and the spring 144 is arranged between the cone valve 13 and the clamping platform 142 on the inner wall of the suction air channel 14, so that the atomizing core sealing gasket 231 is elastically pressed tightly by the elastic pressure of the spring 144 and the moving space of the cone valve 13, and the problem of poor sealing caused by fixed structure errors can be avoided.
