Description

Field of the Invention



[0001] The present invention belongs to the technical field of electronic cigarettes, and particularly relates to a disposable cigarette cartridge, an atomizer, and an electronic cigarette.

Background of the Invention



[0002] At present, electronic cigarette has become a relatively mature smoking alternative on the market. An atomizer is generally powered by a battery, the atomizer includes a tobacco tar storage cavity and an electric heating wire or an atomizing sheet arranged in the tobacco tar storage cavity, and the atomizer heats tobacco tar to generate smoke under electric driving, thereby enabling a user to obtain smoking experience.

[0003] The electronic cigarette in the prior art has the following disadvantages:

First, the tobacco tar cavity is arranged in the shell and is in direct contact with the inner wall of the shell, the user needs to inject the tobacco tar by himself in use, microorganisms such as bacteria or impurities are inevitably brought into the atomizer in a tobacco tar injection process, the quality guarantee period of the tobacco tar is shortened or the smoke taste is affected, thus affecting the user experience; and meanwhile the tobacco tar injection process is cumbersome and the electronic cigarette is inconvenient to use.

Second, the air pressure generated during the normal operation of an ultrasonic atomizing sheet will rush a tobacco tar guide body which is used for guiding the tobacco tar away from the surface of the ultrasonic atomizing sheet to affect the atomization effect, so that the amount of smoke is small.

Third, the cavitation effect generated during the normal operation of the ultrasonic atomizing sheet generates a high temperature, which is liable to cause carbonization damage to the tobacco tar guide body. The existing tobacco tar guide body, the tobacco tar storage device and the ultrasonic atomizing sheet are generally made into an entirety and cannot be randomly changed, and the entirety needs to be changed once a certain component is damaged, so that the use cost is high.

Fourth, the atomizing surface of the ultrasonic atomizing sheet is in contact with the tobacco tar guide body, and the tobacco tar guide body is directly communicated with a suction nozzle. As the ultrasonic atomizing sheet also ejects granular tobacco tar beads while spraying the smoke, and the tobacco tar beads are directly sprayed onto the mouth of the user along an air outlet passage, so that the tobacco tar is wasted, and the user experience is poor.


Summary of the Invention



[0004] The tobacco tar needs to be injected into the existing electronic cigarette by the user, so that the existing electronic cigarette is inconvenient and unsanitary to use, the amount of smoke is small, the replacement of the tobacco tar guide body is inconvenient, the use cost is high, and the user experience is poor. The object of the invention is to provide a disposable cigarette cartridge, an atomizer, and an electronic cigarette in view of the shortcomings of the above prior art.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution:
A disposable cigarette cartridge structurally includes a hollow shell, a tobacco tar storage device located in the shell, a suction nozzle connected with the upper end of the shell, a tobacco tar guide seat connected with the lower end of the shell, and a tobacco tar guide body installed on the tobacco tar guide seat; the tobacco tar guide body extends into the tobacco tar storage device; and an air passage is arranged in the shell, one end of the air passage is communicated with the suction nozzle, and the other end of the air passage is communicated with a heating surface of the tobacco tar guide body.

[0006] By means of the above structure, the cigarette cartridge is disposable, and meanwhile the tobacco tar guide body is integrally changed, thereby facilitating the user replacing and carrying it, being more sanitary and being more effective to improve the sealing property and the safety of the tobacco tar.

[0007] As a preferred mode, the tobacco tar guide seat includes a base, and a tobacco tar pass hole which penetrates through the base in the vertical direction; and the tobacco tar storage device is arranged on an upper surface of the tobacco tar guide seat, and the tobacco tar guide body is inserted from the lower end of the tobacco tar pass hole and penetrates through the upper end of the tobacco tar pass hole until propping against the tobacco tar storage device.

[0008] Further, the air passage includes a vent hole which penetrates through the base in the vertical direction, and an air pipe with one end communicated with the suction nozzle and the other end communicated with the vent hole.

[0009] As a preferred mode, two tobacco tar pass holes are provided and are symmetrically arranged on the two sides of the vent hole; a salient which extends downward and supports the inner side of the tobacco tar guide body is arranged on the edge of one side of each tobacco tar pass hole close to the vent hole on the lower surface of the base, salients are symmetric with respect to the vent hole; and the tobacco tar guide body is inserted from the lower end of the tobacco tar pass hole and penetrates through the upper end of the tobacco tar pass hole to form a U-shaped structure.

[0010] By means of the above structure, the salient is used for supporting the tobacco tar guide body, so that the tobacco tar guide body forms better surface contact with the ultrasonic atomizing sheet, the supported tobacco tar guide body area directly acts on a high-frequency vibration area of the ultrasonic atomizing sheet to generate a large amount of smoke, and meanwhile the following situation is avoided: the ultrasonic atomizing sheet vibrates to generate the cavitation effect with the tobacco tar guide body due to vibration to generate a high temperature to carbonize the tobacco tar guide body (tobacco tar guide cotton). The tobacco tar guide body forms a U-shaped structure, so that the airflow can take away the smoke from the side face of the U-shaped structure.

[0011] Further, a gap is reserved between the air passage and the lower end of the suction nozzle.

[0012] The gap can prevent condensed smoke droplets in the air passage from being sucked into the mouth.

[0013] In a preferred mode, the tobacco tar storage device is a tobacco tar storage body impregnated with tobacco tar and located in the inner cavity of the shell.

[0014] The tobacco tar is stored in a tobacco tar storage medium to prevent the phenomenon of tobacco tar leakage due to the supersaturation of the tobacco tar guide cotton.

[0015] As another preferred mode, the tobacco tar storage device is a tobacco tar cavity arranged in the shell, and the tobacco tar cavity is filled with tobacco tar.

[0016] As a preferred mode, a tobacco tar cup component is arranged in the shell, the tobacco tar cup component includes a sealed tobacco tar cup shell and a tobacco tar cavity located in the tobacco tar cup shell; the bottom of the tobacco tar cup shell of the tobacco tar cup component is sealed by the tobacco tar guide seat, a recessed portion is arranged at the middle of the tobacco tar guide seat, and a tobacco tar isolation seat is installed in the recessed portion; the tobacco tar isolation seat is T-shaped and includes a vertical portion and a flange edge located at the top of the vertical portion, the vertical portion is inserted into the recessed portion, a first gap is reserved between the vertical portion and the inner wall of the recessed portion, the tobacco tar guide cotton is arranged in the first gap, and a tobacco tar pass hole communicated with the tobacco tar cavity is formed in a position corresponding to the tobacco tar guide cotton on the flange edge; and the outer wall of the vertical portion is wrapped with the tobacco tar guide body, the side face of the tobacco tar guide body props against the tobacco tar guide cotton, and the bottom of the tobacco tar guide body props against the ultrasonic atomizing sheet.

[0017] By means of the above structure, the tobacco tar cup component is disposable and can be replaced independently, and the tobacco tar is injected and sealed before leaving the factory, thereby being clean and sanitary, reducing the use cost, being convenient to use and being unlikely to generate the tobacco tar leakage phenomenon.

[0018] Further, a cotton pressing spring is sleeved on the lower end of the vertical portion, the cotton pressing spring is wrapped by the tobacco tar guide body, and the lower end of the cotton pressing spring props against the inner surface of the bottom of the tobacco tar guide body.

[0019] Further, the disposable cigarette cartridge further includes a tobacco tar bead blocking structure, and the tobacco tar bead blocking structure props against one surface of the tobacco tar guide body away from the ultrasonic atomizing sheet; the tobacco tar bead blocking structure includes a tower-shaped spring, a pitch value of the tower-shaped spring is less than or equal to a line diameter value of the tower-shaped spring, the tower-shaped spring is located on one side where the atomizing surface of the ultrasonic atomizing sheet is located, and the axis of the tower-shaped spring is vertical to the ultrasonic atomizing sheet.

[0020] By means of the above structure, the tobacco tar beads ejected from the ultrasonic atomizing sheet can be blocked by the tobacco tar bead blocking structure. Due to the lateral spacing (i.e., the distance between adjacent spring rings) of the tower-shaped spring, the airflow can bypass the spring rings and smoothly flow by the tower-shaped spring along the longitudinal direction; and on the longitudinal direction of the tower-shaped spring, as the pitch value of the tower-shaped spring is less than or equal to the line diameter value of the tower-shaped spring, the tower-shaped spring is projected on the bottom plane to form a whole plane in which the line diameters are connected with and flush with the line diameters, and after the ultrasonic atomizing sheet sprays the tobacco tar beads into the inner part of the tower-shaped spring (the ejection direction is parallel to the axis of the tower-shaped spring), the tobacco tar beads are blocked by the tower-shaped spring and are not splashed into the mouth of the user. At the same time, since the tobacco tar beads sprayed onto the tower-shaped spring will flow back downward along the spiral direction of the tower-shaped spring and are reheated and atomized, the utilization rate of the tobacco tar is high, and the user experience is good.

[0021] Further, the tobacco tar bead blocking structure further includes a pressing member fixedly arranged at the bottom of the tower-shaped spring, an air outlet groove is formed in the pressing member, and the pressing member props against the atomizing surface of the ultrasonic atomizing sheet.

[0022] By the above structure, the good contact between the tobacco tar guide body and the ultrasonic atomizing sheet can be ensured by the pressing member, and the tobacco tar guide body can be prevented from being rushed away from the atomizing surface by the ejection force during the work of the ultrasonic atomizing sheet, thereby ensuring the atomization effect and increasing the amount of smoke. As the air outlet groove is formed in the pressing member, the normal ejection of the smoke from the ultrasonic atomizing sheet is not blocked.

[0023] As a preferred mode, the pressing member is a non-contact planar spiral spring whose axis is vertical to the tower-shaped spring.

[0024] The spacing of the non-contact planar spiral spring is greater than a multiple line diameter and does not affect the smoke injection of the ultrasonic atomizing sheet.

[0027] In a second preferred solution, the tobacco tar bead blocking structure is designed to be integrally formed, so that the manufacturing cost can be reduced, the assembly difficulty can be reduced, and the working reliability can be improved.

[0028] Further, the disposable cigarette cartridge further includes an air pipe, a cigarette cartridge connecting joint is connected to the bottom of the side wall of the shell, the tobacco tar guide seat is arranged in the cigarette cartridge connecting joint, the tobacco tar guide body is a U-shaped tobacco tar guide cotton sheet, the tobacco tar cavity which accommodates the tobacco tar is enclosed among the tobacco tar guide seat, the shell and the air pipe, the bottom surface of the tobacco tar guide body is located below the tobacco tar guide seat, and the two side walls of the tobacco tar guide body are communicated with the tobacco tar cavity through the tobacco tar pass hole in the tobacco tar guide seat; a vertical vent hole is formed in the tobacco tar guide seat, and the vent hole is communicated with the outside through the air pipe; and a limiting portion which props against the top end of the cylindrical spring is arranged on the side wall of the vent hole, and the non-contact planar spiral spring props against the inner bottom surface of the tobacco tar guide body.
