Detailed Description

The technical scheme of the utility model is further explained by combining the attached drawings in the embodiment of the utility model.

The first embodiment is as follows: the utility model provides a filter core for heating incombustible heating utensil, the filter core wholly is cylindrically, offers blind hole 1 from the top downwards as flue gas mixing channel, and the upper end and the external world of blind hole 1 communicate, and one or more micropore 2 are offered to the lower tip of filter core, and the lower extreme of blind hole 1 passes through micropore 2 and external intercommunication. And an external thread 3 is processed on the outer wall of the filter element, and the external thread 3 is used for being in threaded connection with the upper end of the heating pipe 7.

Example two: as shown in figure 3, the filter element for heating the non-combustible heating appliance is made of stainless steel, the filter element is integrally cylindrical, a blind hole 1 is formed from the top to the bottom to serve as a flue gas mixing channel, and the upper end of the blind hole 1 is communicated with the outside.

The lower extreme of filter core has first cylinder face 11, second cylinder face 12 and third cylinder face 13 from last to down in proper order, and wherein first cylinder face 11 diameter is the biggest, and its processing external screw thread 3 is used for cooperating with heating pipe 7 threaded connection. The diameter of the third cylinder surface 13 is less than that of the inner bore diameter of the heating pipe 7 at the matching part, so that the smoke can smoothly pass through the gap between the third cylinder surface and the heating pipe, and the cut tobacco and sundries are difficult to pass through. The diameter of the second cylindrical surface 12 is the smallest, 4 evenly distributed micropores 2 are processed on the second cylindrical surface 12, and the lower end of the blind hole 1 is communicated with the outside. The flue gas enters the micropores 2 through a gap between the third cylindrical surface 13 and the inner wall of the heating pipe 7, then flows through the blind hole 1 to be mixed and cooled, and finally enters the mouth of a smoker.

The diameter of the micro-hole 2 is between 0.1mm and 0.8mm, and the diameter of the blind hole 1 is about 2.5mm, which is the best condition.

As shown in fig. 3, the junction of the first cylindrical surface 11 and the second cylindrical surface 12 forms the sealing end surface 4. The sealing end face is used for being pressed tightly with a step face inside the heating pipe so as to achieve the sealing effect. The sealing requirement here is not high, only a seal formed by pressing two materials together. The smoke can not pass through or can only pass through a very small amount. Because the suction force is not large.

In the use process, the upper end of the filter element can be sleeved with a suction nozzle made of elastic materials such as silica gel/fluororubber and the like, and the suction nozzle is convenient to disassemble and replace.

As shown in fig. 3, the blind hole processing device further comprises a retention bin 14, the retention bin 14 is a cavity with an upper opening formed by reaming the upper end of the blind hole 1, and the lower part of the retention bin 14 is communicated with the blind hole 1.

As shown in fig. 3, at the interception bin 14, filter cotton and a filter element with appropriate sizes can be placed to increase the interception effect, and the filtration effect is further optimized while the strength and the taste are adjusted.

The filter core can be dismantled, conveniently cleans filter core itself to and heating pipe inner space.

The flue gas passes through the structure of filter core, micropore 2 and blind hole 1, cools down, rectifies, filters, adjusts the resistance to suction optimization flue gas quality, can obviously promote subjective suction sensation to reduce harmful substance content.

It will be appreciated that although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
