Abstract
The utility model belongs to the technical field of the cigarette filter rod, concretely relates to heating is cooling filter rod for cigarette, including the plug wrap to and the cooling section of parcel in the plug wrap, the cooling section is held back the capillary gathering by the low of arranging of a plurality of axial and is formed, keep away from tobacco section one end in the cooling section in the plug wrap and still be equipped with first air traffic control, first air traffic control is wrapped up in the plug wrap. The purpose is as follows: through the first air pipe of cooling section cooperation that forms with the low capillary gathering of holding back of axial arrangement for the flue gas forms the venturi effect when the capillary gets into first air pipe, accomplishes cooling and the atomizing to the flue gas, reduces the flue gas temperature when promoting aerosol formation, promotes user's suction and experiences the sense.
Description
Technical Field
The utility model belongs to the technical field of the cigarette filter rod, concretely relates to heating is cooling filter rod for cigarette.
Background
The heating cigarette is a novel tobacco product which adopts a special heat source to heat tobacco substances, so that nicotine, aroma substances and the like in the tobacco substances are heated and volatilized, and smoking experience is brought to consumers.
The tobacco substance is in a closed heating appliance in the smoking process of heating the cigarette, the heat exchange efficiency between the generated high-temperature smoke and the outside is low, and the heating cigarette needs to adopt a special structure and material to carry out cooling treatment on the high-temperature smoke. Generally, the temperature reduction of the heated cigarette is realized by arranging a temperature reduction section.
In the process of heating cigarettes, due to the fact that the smoke quantity of the cigarettes is limited, filter sticks with low suction resistance and less interception are needed, but due to the fact that the generated smoke has high temperature, the traditional cigarette filter stick design cannot meet the requirement of low suction resistance and low interception for cooling. Therefore, how to effectively cool the smoke without affecting the feeling of smokers is a key problem of the design of the heating cigarette filter stick.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: the cooling filter stick for heating the cigarette is characterized in that a cooling section formed by gathering low-interception capillary tubes arranged in the axial direction is matched with a first hollow tube, so that smoke forms a Venturi effect when entering the first hollow tube through the capillary tubes, cooling and atomization of the smoke are completed, aerosol is promoted to be formed, the smoke temperature is reduced, and the smoking experience of a user is improved.
In order to realize the technical purpose, the utility model discloses a technical scheme as follows:
the utility model provides a heating is cooling filter rod for cigarette, includes the plug wrap to and the cooling section of parcel in the plug wrap, the cooling section is held back the capillary gathering by the low of a plurality of axial arrangements and is formed, keep away from tobacco section one end in the cooling section in the plug wrap and still be equipped with first blank pipe, first blank pipe is wrapped up in the plug wrap.
Further defined, the number of the capillaries is 100-3000.
Further limiting, one end, far away from the cooling section, of the first hollow pipe is provided with a tow rod, and the tow rod is wrapped in forming paper. Such structural design filters the particulate matter in the flue gas through the tow stick to further reduce the flue gas temperature, the practicality is stronger.
Further limit, the cooling section is provided with a second hollow pipe at one end far away from the first hollow pipe, and the second hollow pipe is wrapped in the forming paper and is connected with the tobacco section. Such structural design to the second is empty to manage and keeps apart tobacco section and cooling section, avoids tobacco section direct and cooling section contact, and leads to causing the problem of shutoff to the capillary of cooling section.
Adopt above-mentioned technical scheme's utility model, have following advantage:
1. the cooling section formed by gathering the axially-distributed low-interception capillaries is matched with the first hollow tube, so that when smoke enters the first hollow tube through the capillaries, a Venturi effect is formed, the smoke is cooled and atomized, aerosol is promoted to be formed, the smoke temperature is reduced, and the user suction experience is improved;
2. the cooling section that forms with the low capillary gathering of holding back of axial arrangement has the low characteristics of inhaling and hindering the low holding back of hindering, replaces the tow stick among the prior art, cooperates first air duct, forms the venturi effect, accomplishes cooling and atomizing to the flue gas, when promoting aerosol formation, avoids the flue gas high temperature and causes the problem of scalding the mouth.
Drawings
The present invention can be further illustrated by the non-limiting examples given in the accompanying drawings;
FIG. 1 is a schematic structural view of an embodiment of a cooling filter stick for heating cigarettes according to the present invention;
the main element symbols are as follows:
the device comprises forming paper 1, a cooling section 2, a first hollow pipe 3, a tow rod 4 and a second hollow pipe 5.
Detailed Description
The present invention will be described in detail with reference to the drawings and specific embodiments, wherein like reference numerals are used for similar or identical parts in the drawings or the description, and implementations not shown or described in the drawings are known to those of ordinary skill in the art. In addition, directional terms, such as "upper", "lower", "top", "bottom", "left", "right", "front", "rear", and the like, used in the embodiments are only directions referring to the drawings, and are not intended to limit the scope of the present invention.
As shown in figure 1, the utility model discloses a heating is cooling filter rod for cigarette, including plug wrap 1 to and the cooling section 2 of parcel in plug wrap 1, cooling section 2 is held back the capillary gathering by the low of arranging of a plurality of axial and is formed, keeps away from tobacco section one end in cooling section 2 in plug wrap 1 and still is equipped with first air traffic control 3, and first air traffic control 3 is wrapped up in plug wrap 1.
The number of the capillaries is 100-3000.
One end of the first hollow pipe 3, which is far away from the cooling section 2, is provided with a tow rod 4, and the tow rod 4 is wrapped in the forming paper 1. Particulate matter in the flue gas is filtered through the tow rod 4 to further reduce the flue gas temperature, the practicality is stronger.
The cooling section 2 is kept away from first empty pipe 3 one end and is equipped with the empty pipe of second 5, and the empty pipe of second 5 is wrapped up in the plug wrap 1, and is connected with the tobacco section. The tobacco section and the cooling section 2 are isolated by the second hollow pipe 5, and the problem that the tobacco section is directly contacted with the cooling section 2 to block the capillary tube of the cooling section 2 is avoided.
In this embodiment, during the use, the flue gas that the tobacco section produced gets into in the capillary of cooling section 2 through second hollow pipe 5, and reentrant first hollow pipe 3 forms the venturi effect, accomplishes the cooling and the atomizing to the flue gas, carries out the secondary cooling through tow stick 4 at last again, supplies the user to inhale.
The above is to the utility model provides a pair of heating is cooling filter rod for cigarette carries out the detailed introduction. The description of the specific embodiments is only intended to facilitate an understanding of the method of the invention and its core concept. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
