8results about How to "Reduce suction resistance" patented technology

This invention relates to the field of heated cigarette technology, specifically disclosing a filter tip structure and molding method. The filter tip structure includes: a filter rod core, molding paper, and multiple plugs. The filter rod core is cylindrical, and the molding paper is fixedly sleeved on the outer circumferential surface of the filter rod core. The molding paper has multiple guide holes arranged in an array, with m rows along the circumference of the filter rod core and n columns along the axial direction of the filter rod core, where m and n are both integers greater than 0. The multiple plugs are arranged one-to-one with the multiple guide holes, and the plugs can block the guide holes. With this configuration, the smoker can manually remove the plugs before actually smoking. Removing the plugs increases the entry of side airflow, thereby increasing the ventilation rate of the heated cigarette and reducing the draw resistance during smoking. At the same time, removing the plugs can cause the microcapsules containing flavoring to rupture due to friction, releasing the flavoring and giving the smoke its characteristic aroma, effectively improving the smoker's smoking experience.

The present application relates to the field of cigarette technology, and particularly relates to a production method of a heat-not-burn cigarette and a cigarette. The production method of the heat-not-burn cigarette comprises the following steps: common tobacco shred production: mixing a tobacco powder mixture with a porous fiber base material to press a common tobacco sheet with a set thickness, and cutting the common tobacco sheet to obtain common tobacco shreds; heat-conducting tobacco shred production: attaching a heat-conducting metal material on the common tobacco sheet or attaching the heat-conducting metal material on the porous fiber base material to obtain a heat-conducting sheet, the surface density of the heat-conducting sheet being the same as that of the common tobacco sheet, and cutting the heat-conducting sheet to obtain heat-conducting tobacco shreds; and cigarette production: uniformly mixing the heat-conducting tobacco shreds and the common tobacco shreds with a set proportion, and rolling the heat-conducting tobacco shreds and the common tobacco shreds into cigarettes by using a cigarette rolling machine. The present application can improve the heat-conducting performance of the cigarette while not increasing the suction resistance, increase the release amount of smoke during smoking, and ensure the consistency of the product.

The utility model relates to an aerosol generating device, which comprises a heating tube, a heating tube, a heating element and an aerosol generating element, wherein a heating cavity is formed in the heating tube in a penetrating manner; and the base is matched at one end of the heating tube, and an accommodating cavity and an air inlet channel communicated with the accommodating cavity are formed in the base. The heating cavity and the containing cavity are communicated to form a containing channel used for containing at least part of the aerosol generating product, and at least one boss is formed at the end, close to the air inlet channel, of the containing cavity and used for supporting the aerosol generating product. The aerosol generating product is supported by the boss, and the contact area between the base and the bottom of the aerosol generating product can be reduced, so that the air inlet area is increased, the suction resistance is reduced, and the smoke outlet effect is improved.

This application provides an aerosol generating device, which includes an atomizer and a power supply component. The atomizer has an atomization channel. The atomizer and the power supply component together enclose a cavity, the wall of which has multiple air inlets. The air inlets communicate with the atomization channel through the cavity and with the outside of the aerosol generating device. The sum of the minimum cross-sectional areas of all the air inlets is less than the minimum cross-sectional area of ​​the atomization channel. The aerosol generating device in this application uses multiple air inlets. On the one hand, the smaller cross-sectional area of ​​each air inlet helps to increase the airflow velocity, thereby improving the efficiency of expelling larger aerosol generation matrix particles from the aerosol generating device and enhancing the user's inhalation experience. On the other hand, the larger sum of the cross-sectional areas of all the air inlets helps to reduce the suction resistance experienced by the user during aerosol inhalation, improving the user experience.

According to the aerosol generating product, the aerosol generating substrate has improved porosity and reduced draw resistance, and uniform release of aerosol in use is facilitated.

The aluminum ash ball-milling equipment with the good dust collection effect comprises a hopper, a conveying belt and a ball mill, the conveying belt conveys aluminum materials falling from the hopper to the ball mill for ball-milling treatment, the aluminum ash ball-milling equipment further comprises a dust collection fan, a dust collection pipe and at least two steering elbows, the dust collection fan is connected with the dust collection pipe, the dust collection pipe horizontally extends to the upper side of the hopper, and the steering elbows are connected with the conveying belt. The dust collection fan is connected with the top of the hopper in a vertically downward mode after being steered by the first steering elbow and is connected with the top of the hopper in a vertically downward mode after being steered by the second steering elbow, the dust collection fan sucks raised dust in the hopper through the dust collection pipe, the two steering elbows are obtuse-angle steering elbows, and the dust collection pipe is steered by the first steering elbow and then obliquely and downwards extends to the position over the hopper. And the second steering elbow is vertically downwards connected with the top of the hopper. Due to the fact that the portion, close to the top of the hopper, of the dust collection pipe does not adopt a vertical steering elbow with high resistance but adopts an obtuse angle steering elbow with low resistance, dust collection resistance in the dust collection process is remarkably reduced, dust collection efficiency is high, and the dust collection effect is good.
