Description

Atomizer with oil locking device

Technical Field

The utility model relates to a vapour fog generating device's atomizer structure, in particular to atomizer structure with lock oily device.

Background

The currently used inhalation type vapor-fog generating device is generally a device for atomizing special liquid by electric heating. The device can be used in the fields of inhalation therapy and the like, but the device is also an inhalation type steam fog generating device commonly called electronic cigarette. Which includes an atomizer in which a heated atomizing assembly, called an atomizing core, is disposed.

The fixed base of installing in the atomizer of electron smog core of traditional structure, the suction air flue is then connected to the upper end, and intake duct and bipolar electrode are connected to the lower extreme. The cavity between the outer side of the atomizing core and the atomizer shell is an oil storage bin for storing tobacco tar. The casing of atomizing core is provided with the inlet port, and the tobacco tar in the oil storage storehouse can get into the inside heating atomization of atomizing core through the inlet port. Thus, the atomizing core is provided with a structure with three channels, one is a vapor outlet which is connected with the air suction channel; 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 a tobacco tar inlet, namely an oil inlet hole, which is positioned at the opening of the side wall of the atomizing core. Because the air current is unblocked when smoking needs to be guaranteed, therefore air inlet and vapour fog export all need expose in the air for a long time, just at this moment inside the atomizing core with the tobacco tar import intercommunication, the tobacco tar in the oil storage storehouse can pass through the inlet port and get into the atomizing core inside, and then leak out from vapour fog export or air inlet, cause the oil leak phenomenon. And this phenomenon is essentially unavoidable.

The reason for this is that the atomizing core needs to be fixed inside the atomizer, and a channel for leaking oil from the oil inlet to the air inlet and the air outlet is inevitably formed, and this oil leaking channel must be opened for a long time, so that the oil leaking phenomenon cannot be basically avoided.

In order to better realize the functions of atomization and temporary oil storage, the atomization core is internally provided with an oil guide component. The oil guide part is made of fiber or microporous ceramic, and the pore diameter numerical value of micropores with certain capillary action can be selected according to the surface tension of the tobacco tar to control partial leakage of the tobacco tar, but the problem of oil leakage cannot be fundamentally solved. For example, an oil guiding component with a certain pore size designed according to the surface tension of the tobacco tar may cause the surface tension to change when the pressure changes, for example, the pressure may be reduced when a user takes an airplane, and the surface tension of the tobacco tar may be different when the air pressure changes. Extreme phenomena of no oil overflow or oil leakage can easily occur.

In view of the above problems, various oil leakage preventing structures for atomizers have been proposed, and the structure shown in fig. 1 is a structure for preventing oil leakage by rotation. The structure is a structure for rotationally sealing an oil inlet hole of an atomizing core, a cover body 6 'is covered on the periphery of a cylindrical atomizing core 9', and the cover body 6 'is provided with the same oil inlet hole as the atomizing core 9'. When the cover body 6 ' is rotated, the positions of the oil inlet hole of the atomizing core 9 ' and the oil inlet hole of the cover body 6 ' can be changed and are respectively in an aligned state, a staggered state or a middle state. When the oil inlet is in a staggered state, the oil inlet of the atomizing core 9' can be sealed to play a role of preventing oil leakage, the oil inlet is completely opened in an aligned state, and the oil inlet amount can be adjusted in an intermediate state. However, such a rotary type oil leakage preventing structure has the following drawbacks.

The main defects are as follows: among the device of above-mentioned structure, there is the unstable problem in location, outside upper cover 4 ' does not set up and stops positioner, need not to carry out other operations alright easily in order to realize when consequently rotatory outside upper cover 4 ', if unexpected action rotate upper cover 4 ' alright easily open the oil feed passageway, produce the oil leak phenomenon, there is the influence to the safety of product, personnel such as children especially are obtaining the playing process after the product just can easily rotate the upper cover, open the oil feed passageway, can cause the safety problem even. Therefore, in the prior art product, if the rotating part can easily rotate, the positioning difficulty is high; when the positioning is easy, the rotation difficulty is large. It is desirable to provide a latch lock device that prevents easy opening by a child.

Secondly, the outer shell of the atomizing core 9 'and the rotary cover body 6' are both metal cylinder structures, and mutual rotation needs to be ensured, so that certain clearance is required to be arranged for realization. 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.

And then: the assembly degree of difficulty is great, to the cover body 6 'of atomizing core, to realize its rotation, must set up aggregate unit from the upper end or the lower extreme of atomizer to the rotation of exterior rotating member drives the rotation of cover body 6'. As shown in fig. 1, in order to rotate the cover body 6 ', the upper cover 4 ' must be rotated from the outside, the upper cover 4 ' rotates coaxially to drive the suction air channel 3 ' to rotate, and then the cover body 6 ' is driven to rotate, so that the alignment and staggering switching between the oil inlet of the atomizing core and the oil inlet of the cover body can be realized. All parts involved are those contacting the tobacco tar, so that a sealing device is required. In the prior art shown in fig. 1, the cover body 6 ' and the suction air duct 3 ' and the upper cover 4 ' are fixedly connected and are located in the oil storage bin, so that good sealing is required, and the assembly difficulty is increased.

In view of the above, the present inventors have devised an atomizer having an oil lock device, which achieves the function of sealing and locking oil in the form of a rotary seal, a rotary engagement, and a sliding seal, thereby solving the problem of oil leakage of the atomizer.

The atomizer initial state is a state shown in fig. 6, i.e., a state in which the slide cover 11 is located at the second position. At this time, the sliding sleeve outer wall 1103 seals the oil inlet 501 of the sealing member 5, thereby preventing the smoke oil from leaking through the oil inlet 501. When smoking is needed, the atomizing core 9 and the battery box are in butt joint, then the atomizing core 9 is inserted into the installation space in the sealing element 5, the sliding sleeve 11 is jacked up, the atomizing core oil inlet 901 is communicated with the sealing element oil inlet 501 and the atomizing core outer sleeve oil inlet 401 in an aligned mode, and smoking operation can be carried out by introducing tobacco tar. The base 7 and the battery case may be connected by a snap fit or a screw. After smoking, the atomizing core 9 is pulled out, the sliding sleeve 11 is reset again, the outer wall 1103 seals the oil inlet 501, and oil leakage is avoided.

The structure as the rotary oil locking device is operated in such a way that when the atomizing core 9 is not inserted, the rotary component and the fixed component of the atomizer are relatively locked and cannot rotate. At this time, the locking device is locked and locked, and the oil inlet hole 501 of the atomizing core sealing member is sealed by the outer wall 1103 of the sliding sleeve. The oil holes 201, 101 and 301 at the upper ends are in a staggered closed state, and oil leakage does not occur at the upper end and the lower end.

When the smoking operation is needed, the atomizing core 9 is inserted into the installation space of the atomizing core sealing piece 5, and the oil inlet hole is in an open state because the oil injection hole is closed at the moment, so that the atomizing core can take oil for smoking.

When the tobacco tar is required to be injected, no matter whether the atomizing core 9 is pulled down, the elastic clamping block 202 can be pressed to be separated from the clamping effect of the clamping hole 102, so that the relative rotation of the rotating component and the fixed component can be realized, after the rotating component rotates to the position, the oil filling hole is in an open state, the oil inlet hole 901 of the atomizing core is in a closed state, and the oil inlet hole of the atomizing core 9 cannot leak oil during the oil injection from the oil filling hole.

To sum up, the present invention has been described with various embodiments, 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.
