Description

Oil-gas-closing structure of atomizer lock

Technical Field

The utility model relates to a vapour fog generating device's atomizer structure, in particular to lock oil and close gas structure of use on the atomizer.

Background

The currently used inhalation type vapor-fog generating device is generally a device for atomizing special liquid by electric heating, and is the most used 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 the inlet port itself, and tobacco tar in the oil storage storehouse can get into the inside heating atomization of atomizing core through atomizing core inlet port. 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.

Typically, a structure for preventing oil leakage by rotation is provided. 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 has the following disadvantages: (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 place 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 does not enter without holes, the oil leakage phenomenon still can be caused as long as a small gap exists, the problem of oil leakage cannot be fundamentally solved, and the tobacco tar pollution of the electronic cigarette sucking air passage caused by oil leakage still can influence the smoking feeling.

The structure of a slip lock oil has appeared afterwards, is that set up the sliding sleeve outside atomizing core, and the sleeve covers atomizing core and establishes, and the inlet port is not established to sliding sleeve itself, when sliding sleeve slided to cover atomizing core inlet port, just blocked atomizing core oil inlet passageway, avoided atomizing core oil inlet and oil leak. But still have some tobacco tar to remain inside atomizing core because atomizing core inlet port is sheltered from after, still have a little tobacco tar to spill, still can not solve the problem that electron cigarette suction air flue is polluted by the tobacco tar completely.

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. For example, the air inlet and the vapor fog suction air flue of the atomizer, as the smoke oil can leak from the air inlet, a plurality of atomizers are provided with adjusting rings at the air inlet, and the adjusting rings can control the opening and closing of the air inlet, thereby not only realizing the air inlet adjusting function, but also realizing a certain oil leakage preventing function. 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 oral cavity contact as the smog export, more need prevent that the tobacco tar from entering into the smog export, also need set up the device of closing the suction air flue simultaneously, avoids inside the dirty thing drops the 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 structure having an oil lock device and an air shut-off device, which achieves the object of preventing oil leakage and dirt from being sucked out of an air passage in a manner of simultaneously locking oil and shutting off an air flow passage.

Detailed Description

The present invention will be described in detail with reference to the following preferred embodiments, but the embodiments are only for explaining the technical solution of the present invention, and any description thereof does not affect the limitation of the protection scope.

The utility model discloses an overall design thinking sets up slip suction air flue in the atomizing core outside of atomizer, and suction air flue bottom sets up the oil interceptor, and the inside cone valve that sets up of suction air flue. The oil blocking ring is used for blocking an oil inlet channel of the atomizing core to realize the oil locking function, and the conical valve is used for blocking a steam fog outlet of the atomizing core and sucking a channel between air passages to realize the air closing function. And the functions of oil locking and gas closing can be realized simultaneously.

Example 1: this embodiment is one of the preferred embodiments of the present invention.

As shown in fig. 1, 2 and 3, the atomizer lock oil and gas seal structure of the present embodiment is configured such that the electronic cigarette atomizing core 3 is mounted on the atomizer base 4 and is coaxially disposed at the central portion of the atomizer base 4. And the periphery of the atomizing core 3 is provided with a suction air passage 1 which can axially slide up and down, the suction air passage 1 is sleeved outside the atomizing core 3, and the sliding direction is along the axial direction of the atomizing core 3.

As shown in fig. 1 and 2, the inner wall of the suction air channel 1 is connected with the atomizing core 3 in a sealing and sliding manner through a sealing gasket 31 arranged at a steam outlet of the atomizing core 3. And a conical valve 2 is arranged inside the upper position of the suction air channel 1, and the conical valve 2 consists of a solid conical body 22 positioned at the central part and a vent hole 21 arranged at the edge of the solid conical body. The central position of the conical valve 2 is thus impermeable to air, while the outer edge of the vent 21 is permeable to air. The conical surface 23 of the conical valve 2 is arranged facing the seal 31 of the atomizing core and angularly corresponds to the contact surface 311 at the upper end of the seal 31. That is, when the conical valve 2 abuts against the sealing gasket 31 of the atomizing core, the conical surface 23 of the conical valve abuts against the contact surface 311 of the sealing gasket 31 to seal, and the air flow passage between the atomizing core 3 and the suction air passage 1 is closed. And because the contact surface angles correspond to each other, the contact area is enlarged, the sealing area is enlarged, and the effect is also increased.

As shown in fig. 1 and 2, an oil control ring 11 protruding outward is provided at the bottom of the suction air duct 1, and the oil control ring 11 is provided at the bottom end of the suction air duct 1 at the lowermost end of the suction air duct 1. The oil control ring 11 is an annular platform that extends outwardly along the suction air channel 1. In order to realize the sealing and oil locking function by matching with the structure of the oil-stopping ring 11, the upper side of the atomizer base 4 is provided with a sealing gasket 41, the central position of the sealing gasket 41 is provided with a hole, and the central position and the atomizing core 3 form a smoke oil channel 411 together. The height position of the oil inlet 32 of the atomizing core 3 is just located at the position of the tobacco tar channel 411, so as to ensure that the tobacco tar enters the oil inlet 32 of the atomizing core through the tobacco tar channel 411 for atomization.

As shown in fig. 1 and 2, the diameter of the outer edge of the soot passage 411 is smaller than the diameter of the outer edge of the oil control ring 11, that is, the diameter of the inner ring of the seal 41 is smaller than the diameter of the outer ring of the oil control ring 11. When the oil control ring 11 abuts against the sealing gasket 41, the oil control ring 11 can block the tobacco tar passage 411, so as to block the tobacco tar from entering the tobacco tar passage of the oil inlet 32 of the atomizing core, and the tobacco tar cannot enter the atomizing core 3.

The conical valve 2 of the present embodiment is fixed in the suction air duct 1 by interference fit, and the oil control ring 11 is integrally provided at the bottom end of the suction air duct 1. The axial position between the conical valve 2 and the oil control ring 11 is thus fixed, and the axial distance between them is also fixed. The axial distance between the conical valve 2 and the oil control ring 11 needs to be calculated accurately in advance during manufacturing, so that the conical valve 2 and the oil control ring 11 can be linked conveniently, and the functions of the smoke oil channel 411 and the suction air channel 1 can be blocked simultaneously in the linkage process. That is, while the oil control ring 11 abuts against the base gasket 41, the inclined surface 23 of the conical valve 2 can abut against the contact surface 311 of the seal ring 31, and the oil locking and air-lock functions are realized. When selecting the material of the sealing gasket, the material with certain elasticity such as silica gel should be selected as soft as possible. The purpose of the

soft sealing gaskets

41 and 31 is to compensate for assembly errors in the presence of slight assembly errors, as well as to achieve a good sealing effect, due to the compressibility of the soft material.

As shown in fig. 1, it is a sectional structure view of the suction duct 1 at the first position in the present embodiment. At this moment, the electronic cigarette is in a smoking state, the suction air flue 1 at this moment is lifted to a position located at the upper end of the atomizer, the oil control ring 11 is also lifted to a position where the atomizing core 3 is located, the oil control ring 11 is separated from the sealing gasket 41 of the base at this moment, so that the oil inlet channel 411 is opened, and the tobacco tar can enter the atomizing core 3 at this moment. Meanwhile, the conical valve 2 positioned on the inner side of the suction air passage 1 is lifted, the conical valve 2 is separated from the sealing gasket 31 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 rise around the air vent 21 at the outer edge of the conical valve through the steam fog outlet, and the smoke can be sucked out through the suction air passage 1, so that the function of smoking is realized.

As shown in fig. 2, the cross-sectional structure of the suction gas channel 1 in the second position in the present embodiment is shown. The position is in the state that the electronic cigarette locks oil and gas, namely the idle state. At this time, the suction air passage 1 is pressed down, and along with the pressing down of the suction air passage 1, the oil control ring 11 abuts against the base sealing gasket 41 to shield the oil inlet passage 411 and cut off the oil inlet passage, so that the oil leakage phenomenon can be avoided or reduced. Meanwhile, the cone valve 2 is pressed down to tightly abut against a sealing gasket 31 arranged at the steam fog outlet of the atomizing core, and the air channel 1 is cut off and sucked. Thereby avoiding the tobacco tar that spills from atomizing core 3 to flow out from suction air flue 1, also can block the inside passageway of external filth entering atomizing core 3 simultaneously.

As shown in fig. 4, as to how to realize the problem of the axial sliding of the suction air duct 1 at the periphery of the atomizing core 3 in the present embodiment, the following structure can be realized: the upper end of the inner side of the suction air flue 1 can be fixedly connected to an electronic cigarette smoking mouth 5, and the electronic cigarette smoking mouth 5 is axially pushed to realize the axial sliding of the suction air flue 1. And a sliding sealing structure is arranged between the outer edge of the upper end of the suction air channel 1 and the top cover 6 of the atomizer, specifically, a sealing ring 62 is arranged on the top cover to seal the tobacco tar in the atomizer, so that the tobacco tar cannot leak when the suction air channel 1 slides axially. In order to realize the axial positioning of the suction air flue 1 which axially slides, a two-gear clamping structure can be arranged between the atomizer top cover 6 and the outer wall of the suction air flue 1, and the suction air flue 1 can be clamped and positioned at a first position or a second position. As shown in fig. 4, the outer wall of the suction air passage 1 is provided with the fixture block 13, the rotary joint between the atomizer top cover 6 and the suction air passage is provided with an upper annular clamping groove 63 and a lower annular clamping groove 64, and the symmetrical side of the joint is provided with the switching groove 61, and the switching groove 61 is respectively communicated with the upper annular clamping groove and the lower annular clamping groove, so that the fixture block 13 can be switched between the upper annular clamping groove and the lower annular clamping groove through the switching groove 61. When the suction air passage 1 is located at the first position, the clamping block 13 is clamped with the upper annular clamping groove 63 for axial positioning, and when the suction air passage 1 is located at the second position, the clamping block 13 is clamped with the lower annular clamping groove 64 for axial positioning. The first position and the second position are switched by rotating the cigarette holder 5 and then replacing the annular clamping groove with the switching groove 61. Of course, the arrangement of the annular clamping groove and the clamping block can be changed, for example, the annular clamping groove is arranged on the outer wall of the suction air channel, and the clamping block is arranged on the top cover of the atomizer. However, since it is necessary to position the ring slots at the first position and the second position, respectively, the number of the ring slots for positioning should be two.

Example 2: the present embodiment is an improved embodiment based on embodiment 1, and in embodiment 1, the conical valve 2 is of a fixed structure, so the axial distance between the conical valve 2 and the oil control ring 11 is fixed, and only by accurate installation and positioning after the fixed position is designed in advance, the conical valve 2 and the oil control ring 11 can be linked and simultaneously oil and gas can be locked, and a little assembly error is realized by plastic deformation of a soft seal gasket, so the effect is slightly poor. The improvement of the embodiment is that the conical valve 2 is elastically arranged on the inner side of the suction air channel 1, so that the conical valve 2 can elastically slide in a certain axial distance, and further the steam and mist outlet of the atomizing core can be elastically blocked.

The specific structure is shown in fig. 4, the edge of the conical valve 2 is clamped between the clamping platform and the clamping ring 25 on the inner side of the suction air channel 1, so that the conical valve 2 has a certain axial moving space in the suction air channel 1, the pressure spring 24 is arranged between the conical valve 2 and the clamping platform on the inner wall of the suction air channel 1, the elastic pressing of the atomizing core sealing gasket 31 is realized by the elastic pressure of the pressure spring 24 and the moving space of the conical valve 2, and the problem of untight sealing caused by the assembly error of the fixed structure can be avoided.

In this embodiment, an elastic restoring device, such as a return spring 12, may also be disposed between the outer wall of the suction air duct 1 and the atomizer top cover 6, so as to facilitate elastic sliding and elastic positioning of the suction air duct 1, and maintain positioning stability.

The above description is of the preferred embodiment, and variations of equivalent structures may be made by those skilled in the art in light of the above teachings. If the conical valve 2 is changed into an arc valve, a trapezoid valve, etc., the basic purpose of the utility model can be realized, and the effect of gas shutoff is achieved. The structure that protrudes outwards of the oil control ring is removed, the cylinder body of the suction air flue 1 is directly used for extending, the cylinder body directly shields the oil inlet hole of the atomizing core when the cylinder body is at the second position, and the oil locking function can be realized.

To sum up, the present invention has been described with various embodiments and specific implementation manners, and still can be derived from the basic idea of the present invention to those skilled in the art, and the similar structural changes can be obtained. The design and the change of the basic idea of the utility model are all within the protection scope of the utility model.
