Description

[Technical field]

[0001] The present invention relates to the technical field of atomization, and in particular to an atomization core and a liquid reservoir cotton atomization device. [Background technology]

[0002] At present, the liquid storage cotton-based atomizer uses the liquid storage cotton as a carrier for the atomization liquid, which effectively solves the problem of liquid leakage in the atomizer. However, the liquid transmission efficiency is low due to the lack of liquid pressure in the atomization cotton-based atomization core. On the other hand, a high atomization temperature is required for a good feeling of inhalation of the atomization liquid, and high liquid transmission efficiency is required during atomization. At the same time that the atomization core consumes the tobacco liquid, the liquid in the liquid storage cotton is consumed, increasing the air pressure, and a pressure difference occurs between the inside and outside of the liquid storage tank of the atomizer. Then, the external air pressure becomes higher than the air pressure in the liquid storage tank, and the external air enters the liquid storage tank through the porous voids of the liquid guide material, and the air pressure is equilibrated. However, this air occupies some of the voids in the liquid guide material, resulting in insufficient or uneven liquid guide of the liquid guide material, and the liquid transmission speed in the liquid guide material is slowed down.

Furthermore, a first through hole 3211 is provided at the center of the first body portion 321. An air guide tube 322 extends downward on the periphery of the first through hole 3211. The air guide tube 322 is connected to the upper end of the mounting frame 341. For example, the air guide tube 322 may be tightly fitted to the mounting frame 341.

In this embodiment, the fitting portion 21 may be fixed to the upper end of the housing 1 by interference fit, or may be fixed by hook connection or screw connection. The mouthpiece portion 22 may have a substantially columnar structure.

Alternatively, the upper end in the height direction of the liquid-guiding cotton 3421 blocks a part of the air hole 3412. As can be understood, the liquid-guiding cotton 3421 does not block, block or cover the air hole 3412. Alternatively, the liquid-guiding cotton 3421 partially blocks, blocks or covers the air hole 3412.

[0049] In this embodiment, the mounting frame 341 has a hollow tubular structure, and may have a cylindrical structure. Preferably, the mounting frame 341 is made of a hard insulating material, such as phenol plastic, polyurethane plastic, epoxy plastic, unsaturated polyester plastic, furan plastic, organic silicon resin, propylene-based resin, or modified resin thereof. basic material Of course, the mounting frame 341 may be made of a tubular metal, such as stainless steel, copper iron, aluminum, aluminum alloy, etc., with electroplating applied to the surface of the metal. It is understood that the material of the mounting frame 341 can be selected and set according to actual needs, and is not specifically limited here.

[0050] Preferably, the wall thickness of the mounting frame 341 is 0.4 mm or less.

[0052] In this embodiment, the air holes 3412 are provided at intervals. For example, the air holes 3412 may be provided at intervals on the same horizontal plane, or may be provided at intervals in the height direction. The air holes 3412 may also be arranged in a line or staggered.

[0053] As shown in Fig. 11, preferably, the air hole 3412 can communicate with the liquid supply hole 3411. During assembly, the liquid-conducting cotton 3421 is attached to the mounting frame 341 to completely block the liquid supply hole 3411, and the exposed portion is Air hole 3412 provides ventilation.

[0056] The heating body may have a columnar structure and may include conductive parts 34221 provided at both ends and a heating part 34222 connected to the conductive parts 34221. The electrode lead wire 34223 is provided so that one end is provided to the conductive part 34221 and the other end extends downward. As can be understood, the heating body may have a C-shaped structure as shown in FIG. 12. Also, the heating body may have a spiral structure as shown in FIG. 13. Also, the heating body may have a tubular structure as shown in FIG. 14.

A positioning groove 3432 for inserting the electrode lead wire 34223 is provided on the circumferential side surface of the fixed base 343. A plurality of the positioning grooves 3432 may be provided at intervals in the circumferential direction. Also, an inclined guide surface may be provided on the side facing the heat generating body. Preferably, the second body portion 331 is further provided with a mounting groove 3312, and the fixed base 343 is attached in the mounting groove 3312. Preferably, the electrode lead wire 34223 is inserted into the second seal member 33 and electrically connected to the power supply module 4.

[0059] As can be seen, the mounting frame 341 of the atomizing core 34 is provided with an air hole 3412. In this way, during use, external gas can enter the liquid storage tank or the liquid storage cotton 35 through the air hole 3412, effectively preventing the gas from occupying the porous voids of the liquid-guiding cotton 3421. As a result, the liquid is guided through the liquid-guiding cotton 3421 more sufficiently and uniformly, improving the comfort of inhalation and the service life of the liquid-guiding cotton atomizing device.

[0061] The power supply module 4 further includes a base 42 accommodated in the opening at the bottom of the housing 41. The inner circumference of the housing 41, the bottom surface of the second main body 331, and the top surface of the base 42 are combined with each other to form an installation space. The power supply module 4 further includes a battery 43 provided in the installation space. The outer circumference of the battery 43 and the inner circumference of the housing 41 maintain a predetermined gap to form an airflow path. Preferably, a stopper arm 332 extends downward from the periphery of the second main body 331. The stopper arm 332 can restrict the position of the battery 43 by pressing the upper edge of the battery 43, and thereby maintain a certain space between the power supply module 4 and the atomization module 3.

[0062] In this embodiment, the base 42 may include a bottom plate 421 and an annular portion 422 formed by extending upward from the periphery of the bottom plate 421. A number of mounting portions 423 are provided at intervals on the upper surface of the bottom plate 421. The mounting portions 423 and the annular portion 422 cooperate with each other to allow the bottom of the battery 43 to be mounted thereon.

[0063] Further, the base 42 is provided with an air supply path 424. The air supply path 424 is provided with an airflow sensor switch 44 connected to the battery 43. The air supply path 424 can be formed to penetrate the upper and lower surfaces of the bottom plate 421, and a groove 425 is relatively recessed in the inner wall. The airflow sensor switch 44 is provided in the groove 425. Furthermore, the mounting part 423 is provided to avoid the air supply path 424. When the user holds the mouthpiece 2 in his / her mouth and inhales, a change in air pressure occurs inside the liquid storage cotton atomizing device, and the airflow sensor switch 44 is turned on. As a result, an electric circuit is formed between the battery 43 and the heat generating member 3422, and the atomizing core 34 starts to generate heat, evaporating the liquid for atomization on the liquid-conducting cotton 3421. The evaporated steam is mixed with air to form an aerosol mixture, which enters the user's mouth.

[0064] Furthermore, a protrusion is provided downward on the bottom of the base 42. A mounting protrusion 121 is formed in the center of the bottom wall 12 of the housing 1 so as to protrude upward, and the protrusion abuts against the mounting protrusion 121. An air supply through hole 122 is provided in the bottom wall 12 of the housing 1. The air supply through hole 122 communicates with an air supply path 424. Preferably, the air supply through hole 122 may be provided in the mounting protrusion 121 or on both sides of the mounting protrusion 121. In this embodiment, the first seal member 32, the second seal member 33 and the base 42 may be silicone members.

[0065] As can be seen, the liquid storage cotton atomizing device includes the atomizing core 34, and the mounting frame 341 of the atomizing core 34 is provided with an air hole 3412. In this way, during use, external gas can enter the liquid storage tank or the liquid storage cotton 35 through the air hole 3412, which can effectively prevent the gas from occupying the porous voids of the liquid-guiding cotton 3421. As a result, the liquid guided by the liquid-guiding cotton 3421 is more sufficient and uniform, improving the comfort of the liquid storage cotton atomizing device and the service life of the liquid storage cotton.
