Description

Bottom bracket of heat-not-burn smoking set and smoking set using the bottom bracket

technical field

The utility model relates to the field of heat-not-burn cigarettes, in particular to a bottom bracket of a heat-not-burn smoking set and a smoking set using the bottom bracket.

Background technique

In recent years, heat-not-burn cigarettes have attracted the attention of consumers since they appeared in the cigarette consumption market, and their market share has increased year by year. The so-called "heat-not-burn cigarettes" means only heating the cigarettes without burning them. The heating temperature is obviously lower than the ignition point of the cigarettes. Therefore, the heater and the cigarettes need to be used in conjunction with the heat-not-burn cigarettes. , The cigarette is made up of tobacco and its derivatives, and the heater is the smoking set.

In the smoking set, the heating chamber is used to heat the cigarette sticks located therein, and it generates heating and heating through electric conversion. The heating principle can be directly heated by electric heating elements, or electromagnetic induction heating can be carried out by electromagnetic induction elements. At present, the type of electronic heating element can adopt the cylinder wall type to heat the side wall of the cigarette, or use the insertion type to heat the center inside the cigarette. No matter which heating method is used, the heating cavity in the smoking appliance must keep air through to ensure the suction effect. Therefore, there must be vent holes in the structure of the smoking appliance that is in direct contact with the cigarettes to ensure air circulation. During use, the air will follow the user’s inhalation, enter the heating chamber through the vent hole and flow through the cigarette. The user's inhalation enters the oral cavity.

The structure in which the smoking appliance directly contacts and acts on the cigarette can hold and fix the cigarette through the bottom bracket and/or the side jacket. Generally speaking, the side jacket and the bottom bracket work together. The side jacket can ensure that the cigarette is in a vertical state in the smoking set without tilting. The bottom bracket can ensure the height of the cigarette in the smoking set, so that the cigarette sticks in the smoking set. The internal fixation is in place, so that the cigarette is stably in the effective heating range, so as to ensure the effective realization of the heating function.

In order to realize air circulation in the cigarette branch, a through hole must be opened at the center of the bottom of the bottom bracket. In general, the shape of the through-hole is the same as the shape of the cross-section of the plug-in heating element, for example, for a pin-type heating element, the shape of the through-hole is circular, and for a sheet-type heating element, the shape of the through-hole is linear . However, unlike traditional cigarettes that are completely exposed to the air environment, the air permeability of heat-not-burn cigarettes is significantly lower than that of traditional cigarettes, so that users need to pay more for suction when using them. This means that with each puff of a heat-not-burn cigarette, the gas velocity of the smoke is significantly faster than that of a regular cigarette, resulting in the conversion of the air of the heat-not-burn cigarette into smoke As a result, the time for the gas of the heat-not-burn cigarette to adhere to the aroma is shorter, and the composition of the aroma and smell substances in the smoke is lower, thereby reducing the pleasure of smoking the smoke, and it is difficult to achieve the ideal smoking. Effect.

Contents of the invention

In order to solve the disadvantages of the unsatisfactory suction effect of heat-not-burn cigarettes in the prior art, the purpose of this utility model is to provide a bottom bracket for a heat-not-burn smoking set and a smoking set using the bottom bracket, which can Significantly improve the smoking effect of heat-not-burn cigarettes, provide users with a uniform and full aroma during the smoking process, and significantly improve the pleasurable feeling of smoking heat-not-burn cigarettes.

According to one aspect of the present invention, there is provided a bottom bracket of a heat-not-burn smoking appliance, the bottom of which is provided with a through hole, wherein the shape of the bottom through hole is different from that of the cross-section of the inserted heating element.

Preferably, the shape of the bottom through hole is non-centrosymmetric.

Preferably, the shape of the through hole at the bottom of the bottom bracket of the smoking set is fan-shaped or irregular.

Preferably, the shape of the through hole at the bottom of the smoking set base is moon-shaped.

Preferably, the area of the bottom through-hole shape is much larger than the insertion hole area required by the insertion-type heating element, so as to maintain a sufficient ventilation gap between the bottom through-hole and the insertion-type heating element. More preferably, the area of the through hole at the bottom is more than twice the maximum cross-sectional area of the plug-in heating chip.

According to another aspect of the utility model, a heat-not-burn smoking appliance is provided, which is characterized in that: the smoking appliance is provided with the above-mentioned bottom holder.

The bottom bracket of the smoking set is used to fix the position of the cigarette, so that the cigarette is stably within the effective heating range, so that the heating element can evenly heat the cigarette. At the same time, the through hole is set on the bottom bracket of the smoking set to form the cigarette Air inlet. In current heat-not-burn smoking appliances, the through holes at the bottom of the bottom bracket are all centered on the center of the bottom bracket, and the shape is a regular standard shape. Specifically, for the tube-type heating element, the shape of the through hole is circular; for the needle-type heating element, the shape of the base of the smoking appliance is circular, as shown in Figure 3; for the sheet-type heating element, In other words, the shape of the base of the smoking set is a corresponding linear shape, as shown in Figure 4. The inventors have found through research that in the prior art, the so-called standard shape of the bottom through hole is not conducive to improving the air circulation condition of the heat-not-burn cigarette, resulting in a small through hole area, a small air intake, and a low smoke concentration. Low, low utilization rate of aroma components, incomplete effect of the most important tobacco material components in cigarettes, uneven smoking taste and other bad conditions.

In view of this, the inventor has improved the shape of the bottom through hole of the bottom bracket, that is, the shape of the bottom through hole is formed into a non-centrosymmetric shape. It is found through research that this improvement can produce significant beneficial technical effects. That is, it is possible to realize the delivery state that the air presents a non-uniform flow rate when it enters the cigarette through the bottom through hole. More specifically, since the shape of the bottom through hole is different from the shape of the cross section of the insertion type heating element, and the bottom through hole is asymmetrical in shape, the area of the bottom through hole is also asymmetrically distributed. Since the air flow rate is larger on the side with a larger through-hole area at the bottom, the aroma and smell substances of the smoking substance on this side of the cigarette can be lost faster. In this way, once the heat-not-burn cigarette is started to be used, in the process of continuous heating of the cigarette holder by the heating element, the loss rate of the aroma and smell substances of the smoking substance on the side with the smaller through-hole area at the bottom is slower than that at the side with the smaller through-hole area at the bottom. In this way, during the user's inhalation process, the aroma substances on the side with the smaller through-hole area at the bottom of the cigarette can be more fully mixed with the air flowing through the cigarette to accumulate and increase concentration, thereby contributing to The smoker obtains a relatively dense smoke; when the user smokes next time, because the aroma substances on the side with the larger hole area at the bottom have not been fully released in a short time, and the large amount of smoke stored on the other side The gas will be given priority to the suction, which can ensure that the aroma and smell substances in the cigarette are continuously gathered and alternately transported, so that the high-quality smoking taste can be maintained at all times in multiple puffs, and the existing gap in the taste during each puff can be reduced. difference, so that once the cigarette is started to be smoked for many times, it can ensure that the smoke volume and smoke state are uniform, the puffing experience is always consistent, and the puffing taste is uniform, eliminating the need for existing heat-not-burn types in puffing. There are adverse situations such as "a certain puff is easy to smoke", "a certain puff is not easy to smoke", "differences in puffing experience during the puffing process", "the more you puff, the harder it is to puff", etc.

Detailed ways

Below, the utility model will be described in detail in conjunction with the accompanying drawings.

Taking a smoking appliance with an inserting heating element as an example, as the base 101 holding the cigarette 200, in this embodiment, the shape of the through hole adopts the moon shape as shown in FIG. 5 . Moreover, as shown in FIG. 5 , this moon shape is actually a fan-shaped through hole added on the basis of the central through hole. From the comparison of FIG. 5 with FIG. 3 and FIG. 4 , it can be clearly seen that the area of the through-hole shape of the base 101 is much larger than the area of the insertion hole required by the insertion-type heating element. Since the smoking set 100 adopts this special-shaped through-hole, the central through-hole part can ensure the smooth insertion of the heating element, and the additional fan-shaped through-hole can significantly increase the air flow rate. The larger the fan-shaped arc, the larger the area of the through-hole. The greater the air flow rate, the better the effect of improving the air circulation of the cigarette, so that the high-quality smoking taste can be maintained for multiple puffs, and the difference in the taste of each puff can be reduced. During the process of smoking a cigarette for multiple times, it can ensure that the smoke volume and smoke state are uniform, the puffing experience is always consistent, and the puffing taste is uniform. Of course, due to the supporting function of the bottom bracket, the fan-shaped included angle is less than 360°.

Tests have further proved that, for example, setting the area of the through hole at the bottom of the bottom support to more than twice the maximum cross-sectional area of the insert-type heating sheet can further increase the effect of improving air circulation through the cigarette.

The above content is only the best embodiment of the utility model. It should be emphasized that on the premise of not departing from the concept of the utility model, various modifications and improvements of the utility model made by those skilled in the art should fall within the protection scope of the utility model.
