Description

Oil pushing and feeding atomizer
Technical Field
The invention relates to an improvement of an electronic cigarette atomizer structure, in particular to an oil pushing and feeding atomizer.
Background
The existing electronic cigarette is used for adjusting the smoke quantity in a voltage, power and temperature adjusting mode, and the power adjusting mode is adopted at the end, so that the energy input is not well matched with the atomization capability of the atomizer, and the phenomena of dry burning of the atomizer or poor atomization effect caused by excessive smoke quantity are easily caused; in addition, the tobacco tar in the existing electronic cigarette oil storage cabin is soaked in the oil guide cotton and the heating element for a long time, and the temperature of the heating element can heat the tobacco tar in the oil storage cabin when the atomizer works, so that the tobacco tar is easy to deteriorate; the existing electronic cigarette atomizer is easy to leak oil at high and low temperatures in a tobacco tar storage mode and a tobacco tar permeation mode; the existing liquid injection mode of the electronic cigarette is to inject tobacco tar into an atomizer or a tobacco tar bottle, then conduct the tobacco tar to an electric heating wire for heating through the capillary action of the oil guiding cotton, and the tobacco tar is transmitted by the capillary action without accurate controllability in the aspect of tobacco tar transmission quantity, so that mismatching between tobacco tar supply quantity and heating power of an atomizer heating wire is often caused, and phenomena of poor atomization effect and the like are caused due to dry burning of the atomizer or excessive tobacco tar quantity.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides the oil pushing and feeding type atomizer which can feed the tobacco tar in an oil pumping mode, accurately control the tobacco tar delivery quantity by controlling the output flow of the pump, ensure that the tobacco tar input quantity is easier to match with the atomization capability of the atomizer, ensure that the tobacco tar does not need to soak the oil guiding cotton and the heating component for a long time, is not easy to cause the degradation of the tobacco tar, and does not leak oil at high and low temperatures, during vibration or oil pumping.
In order to solve the technical problems, the invention adopts the following technical scheme:
an oil pushing and feeding type atomizer comprises an atomizer body 1 with an internal atomization cavity, wherein an oil feeding channel 13 is arranged on the atomizer body 1, the outlet of the oil feeding channel is blocked by an oil guiding element 111, at least a part of the outer surface of the oil guiding element 111 is exposed to the atomization cavity, and the oil guiding element 111 is in contact with a heating element 112.
Wherein the outlet of the oil inlet channel 13 is blocked by the oil guiding element 111, which directs the oil guiding element 111 to be positioned at the outlet of the oil inlet channel 13 in a manner of providing resistance. "blocking" is to be understood broadly herein to include both the free or held placement of the oil guiding element 111 at the outlet of the oil feed channel 13, and the plugging of at least a portion of the oil guiding element 111 into the interior of the oil feed channel 13, and the covering of the oil guiding element 111 outside the outlet of the oil feed channel 13. In addition, it is particularly emphasized that the "blocking" merely means that the outlet of the oil feed channel 13 is macroscopically blocked, while at a microscopic level, the tobacco tar can still be conducted inside the oil guide element through the channels or voids inside the oil guide element.
The outlet of the oil inlet passage 13 is blocked by the oil guide member 111, which creates a certain resistance in the oil inlet passage, facilitates maintenance of a stable external pumping pressure, and allows the tobacco tar to be pumped into the oil guide member under a certain pressure, and to be heated and atomized via further transmission inside the oil guide member to the heating member. And because the outlet of the oil inlet channel 13 is blocked by the oil guide element 111, no matter in which direction the atomizer is placed, the tobacco tar can only be pumped into the oil guide element, and can not be scattered elsewhere, thus ensuring oil leakage prevention. If the outlet of the oil feed passage 13 is not blocked by the oil guide member 111, the tobacco tar may be sprayed to a place outside the oil guide member under external pump pressure, resulting in oil leakage, waste, and internal pollution.
Preferably, the oil guide member 111 is held by a holder to block the outlet of the oil feed passage 13. This has the advantage that the oil guiding element is not pushed up under the pumping pressure during pumping out from blocking the outlet of said oil inlet channel 13. Such a holder may be any other component within the nebulization chamber. Preferably, the heat generating element 112 is used as the holder.
Wherein the oil guiding element 111 may be in the form of a porous body, a fiber bundle or a fiber mat, or any combination of the above. There is no particular requirement on the material and shape thereof, as long as it can guide oil and can reliably block the outlet of the oil inlet passage 13.

In the case where the oil guide member 111 is in the form of a fiber mat, a central circular region thereof may be in contact with the circular heating plate, and an outer peripheral annular portion thereof blocks an outlet of the oil inlet passage in the shape of a ring, or conversely, the tobacco tar is transferred in a radial direction of the oil guide member by an external oil pressure and is heated to be atomized.
There is no particular requirement on the overall shape, cross-sectional shape and number of the oil feed passages 13. Preferably, the cross-sectional shape of the outlet of the oil feed passage 13 may be circular or annular, and accordingly, the shape of the portion of the oil guide member 111 for blocking is matched with the cross-sectional shape of the outlet of the oil feed passage 13. For example, in the case that the cross-section of the outlet of the oil inlet channel 13 is annular, the oil guide cotton is also arranged in an annular shape, one side surface of the ring blocks the outlet of the oil inlet channel 13, the other side surface of the ring is exposed to the atomizing chamber, and at least one section of the ring is wound with a heating wire.
