Description
Technical Field
The invention belongs to the field of electronic cigarettes, and particularly relates to a piston oil pushing type electronic cigarette.
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 element 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 an oil guiding element, 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 such as poor atomization effect are caused due to dry burning of the atomizer or excessive tobacco tar quantity.
Disclosure of Invention
The invention aims to solve the technical problems: the piston oil pushing type electronic cigarette is good in sealing performance, and is difficult to cause deterioration of tobacco tar, liquid leakage and convenient and fast to replace due to the fact that the tobacco tar is used up when the electronic cigarette is impacted or vibrated at high and low temperatures.
In order to solve the technical problems, the invention adopts the following technical scheme:
a piston oil pushing type electronic cigarette, comprising an electronic cigarette body 4 and an atomizer 5 which are connected with each other, wherein:
the atomizer 5 comprises an atomizer body 50 with an internal atomization cavity, an oil inlet channel 53 is arranged on the atomizer body 50, the outlet of the oil inlet channel is blocked by an oil guide element 511, at least a part of the outer surface of the oil guide element 511 is exposed to the atomization cavity, and the oil guide element 511 is in contact with a heating element 512;
the electronic cigarette comprises an electronic cigarette body 4, wherein a piston oil pushing assembly is arranged in the electronic cigarette body 4 and comprises a piston pushing type oil storage bottle and a transmission mechanism 3, the piston pushing type oil storage bottle comprises a bottle body 1 with a piston cavity 10, a slidable piston body 11 is arranged in the piston cavity 10, and a tobacco tar outlet is arranged on the bottle body 1 opposite to the piston body 11; wherein the outer side of the piston body 11 is detachably connected with the transmission mechanism 3.
Wherein, the outlet of the oil inlet channel 53 is blocked by the oil guiding element 511, which directs the oil guiding element 511 to be positioned at the outlet of the oil inlet channel 53 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 at the outlet of the oil feed passage, and the plugging of at least a portion of the oil guiding element into the interior of the oil feed passage, and the covering of the oil guiding element outside the outlet of the oil feed passage. 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 feed passage 53 is blocked by the oil guide member 511, which creates a certain resistance in the oil feed 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 element. And because the outlet of the oil inlet passage 53 is blocked by the oil guide member 511, no matter in which direction the atomizer is placed, the tobacco tar can only be pumped into the oil guide member without being sprayed or scattered elsewhere, ensuring oil leakage prevention. If the outlet of the oil feed passage 53 is not blocked by the oil guide member 511, 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 511 is held by a holder to block the outlet of the oil feed passage 53. 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 53. Such a holder may be any other component within the nebulization chamber. Preferably, the heat generating element 512 is used as the holder.
Wherein the oil guiding element 511 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. For example, the oil guide member 511 may be oil guide cotton, the heating member 512 is a heating wire, at least a portion of which is arranged in a winding manner, or at least a portion of which is arranged in an alternate winding manner; alternatively, the oil guiding element 511 is in the form of a porous body selected from a porous ceramic body, a sponge body or a porous carbon material body, and the heating element 512 is a heating wire or an electric heating sheet; alternatively, the oil guiding element 511 is in the form of a fiber mat selected from a carbon fiber mat or a refractory fiber mat, and the heating element 512 is an electric heating plate or an electric heating block. In the case where the oil guide member 511 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 511 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.
