Description

Technical Field

[0001] The utility model relates to the technical field of filter cigarette holders, in particular to an S-shaped flue optimized filter cigarette holder. Background Art

[0002] A filter cigarette holder is a device used to reduce the inhalation of harmful substances when smoking. It usually consists of two parts: a cigarette holder body and a filtering part. Through the pore structure of the filtering material, solid particulate matter in the smoke, such as tar and soot, is blocked and intercepted. Larger particles will be blocked on the surface or pores of the filtering material when passing through the filter tip and cannot enter the smoker's mouth and respiratory tract, significantly reducing the content of harmful substances such as tar and nicotine entering the human body when smoking, thereby reducing the harm of smoking to health. Although it cannot completely eliminate the harm, it can reduce the degree of harm to a certain extent.

[0003] In the prior art, due to the structural disadvantages of the filter tip, the flow path of the smoke in the filter tip is short, which results in a reduction in the contact area between the smoke and the filtering material. Harmful substances cannot be effectively adsorbed by the filtering material, and at the same time, the heat exchange efficiency of the smoke on the inner wall of the filter tip is also reduced. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides an S-shaped flue optimized filter cigarette holder, aiming to improve the problems of reduced contact area between the smoke and the filtering material, ineffective adsorption of harmful substances by the filtering material, and reduced heat exchange efficiency of the smoke on the inner wall of the filter tip.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] The S-shaped flue optimized filter cigarette holder includes a cigarette tube. One end of the cigarette tube is fixedly connected with a connection port, and a smoke inlet is opened inside the connection port. A cigarette sleeve is slidably connected to the inner wall of the cigarette tube. One end of the cigarette sleeve is fixedly connected with a connection cylinder, and circular holes are opened on the outer wall of the connection cylinder. One end of the connection cylinder away from the cigarette sleeve is fixedly connected with a first fixing column, and one end of the first fixing column away from the connection cylinder is fixedly connected with a second fixing column. A spiral protrusion is fixedly connected to the outer wall of the second fixing column, a cross block is fixedly connected to the outer wall of the first fixing column, and an air vent gap is opened on the outer wall of the cross block.

[0007] Preferably, the material of the cigarette tube is transparent plastic.

[0008] Preferably, the number of the cross blocks is seven, and they are distributed in a linear array on the outer wall of the first fixing column, and the directions of two adjacent cross blocks are opposite.

[0009] Preferably, the outer diameter of the smoke sleeve is the same as that of the cross block, the outer wall of the cross block is in close contact with the inner wall of the smoke pipe, and the outer diameter of the smoke sleeve is the same as the inner diameter of the smoke pipe.

[0010] Preferably, the outer wall of the spiral protrusion is in close contact with the inner wall of the smoke pipe.

[0011] The utility model has the following beneficial effects:

[0012] 1. In the utility model, when the flue gas passes through all the cross blocks, it will reverse multiple times. Finally, it forms a cavity between the spiral protrusion and the smoke pipe, and flows spirally into the interior of the connection port and reverses again. The multiple reversals of the flue gas extend its flow path in the filter tip, enhance the filtering effect, and improve the filtering efficiency.

[0013] 2. In the utility model, when the flue gas passes through all the cross blocks, it will reverse multiple times and exchange heat with the inner wall of the smoke pipe, which helps to reduce the temperature of the flue gas, make the inhaled flue gas milder, and reduce the irritation to the respiratory tract.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Refer to Figure 1 - Figure 3, An embodiment provided by the present utility model: an S-shaped flue optimized filter cigarette holder, including a cigarette tube 1, one end of the cigarette tube 1 is fixedly connected with a connection port 2, an inlet port 3 is opened inside the connection port 2, a cigarette sleeve 4 is slidably connected to the inner wall of the cigarette tube 1, one end of the cigarette sleeve 4 is fixedly connected with a connection cylinder 5, circular holes 6 are opened on the outer wall of the connection cylinder 5, one end of the connection cylinder 5 away from the cigarette sleeve 4 is fixedly connected with a first fixing column 7, one end of the first fixing column 7 away from the connection cylinder 5 is fixedly connected with a second fixing column 8, a spiral protrusion 9 is fixedly connected to the outer wall of the second fixing column 8, a cross block 10 is fixedly connected to the outer wall of the first fixing column 7, and a ventilation notch 11 is opened on the outer wall of the cross block 10;

[0021] Specifically, the flue gas enters the multi-section cavity formed between the cigarette tube 1 and the cross block 10 through the circular holes 6, and then passes through the ventilation notches 11 opened on the outer wall of the cross block 10 in sequence. When the flue gas passes through all the cross blocks 10, it will reverse multiple times. Finally, it passes through the spiral cavity formed between the spiral protrusion 9 and the cigarette tube 1 and spirally flows into the inside of the connection port 2. During this process, the flue gas will reverse again.

[0022] Refer to Figure 1 , the material of the cigarette tube 1 is transparent plastic;

[0023] Specifically, the material of the cigarette tube 1 being transparent plastic allows the situation inside the cigarette tube 1 to be observed.

[0024] Refer to Figure 1 - Figure 3 , the number of the cross blocks 10 is seven, and they are arranged in a straight line array on the outer wall of the first fixing column 7, and the directions of two adjacent cross blocks 10 are opposite; the outer diameter of the cigarette sleeve 4 is the same as the outer diameter of the cross block 10, the outer wall of the cross block 10 is in mutual fit with the inner wall of the cigarette tube 1, and the outer diameter of the cigarette sleeve 4 is the same as the inner diameter of the cigarette tube 1; the outer wall of the spiral protrusion 9 is in mutual fit with the inner wall of the cigarette tube 1;

[0025] Specifically, due to the first fixing column 7 and the cross blocks 10 being arranged in a straight line array on the outer wall of the first fixing column 7 and the directions of two adjacent cross blocks 10 being opposite, it is beneficial for the flue gas to reverse multiple times when passing through. Since the outer diameter of the cigarette sleeve 4 is the same as the outer diameter of the cross block 10, it can form multi-section cavities with the cigarette tube 1 for the flue gas to flow through. Since the spiral protrusion 9 is in mutual fit with the inner wall of the cigarette tube 1, it can form a spiral cavity with the cigarette tube 1 for the flue gas to pass through.

[0026] Working principle: When in use, one end of the cigarette filter tip is slid into the inner wall of the cigarette sleeve 4, and then air is inhaled through the connection port 2. During the inhalation process, the smoke enters the cavity formed between the cigarette tube 1 and the cross block 10 through the round hole 6, and then passes through the ventilation notches 11 opened on the outer wall of the cross block 10 in sequence. Since the number of cross blocks 10 is seven and they are arranged in a linear array on the outer wall of the first fixed column 7, and the directions of two adjacent cross blocks 10 are opposite. When the smoke passes through the first cross block 10, it enters the cavity formed by the first cross block 10, the second cross block 10 and the cigarette tube 1 through the ventilation notch 11 opened on the outer wall of the cross block 10, and then passes through the ventilation notch 11 opened on the outer wall of the second cross block 10. The smoke will reverse many times when passing through all the cross blocks 10, and finally passes through the cavity formed between the spiral protrusion 9 and the cigarette tube 1, and spirally flows into the interior of the connection port 2 and reverses again. The multiple reversals of the smoke extend its flow path in the filter tip, enhance the filtering effect and improve the filtering efficiency.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
