Description

Technical Field

[0001] This utility model relates to the field of cigarette holder technology, and in particular to a filter cigarette holder. Background Technology

[0002] Existing cigarette holders are present in every cigarette, but they only serve a filtering function. However, as people's living standards improve, more and more people prefer to use an external filter when smoking, firstly to reduce the amount of tar and other pollutants inhaled, and secondly to enhance the smoker's image. However, most current cigarette holders do not expose the filter core inside, serving only a filtering function and lacking any decorative effect. Therefore, to further enrich the product range and meet the diverse needs of users, it is necessary to develop new cigarette holders. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a filter cigarette holder that can effectively solve the aforementioned problems.

[0006] It also includes a positioning groove coaxially disposed on the inner wall of the tube, and a column filter element disposed in the positioning groove; the side wall of the column filter element is provided with a pattern display position, and the tube is provided with a transparent part corresponding to the pattern display position;

[0007] It also includes a sealing plug at the front end of the positioning groove to seal the column filter element in the positioning groove, wherein the front outer side wall and the rear end face of the sealing plug are respectively provided with an air outlet and an air inlet that are connected to each other.

[0008] The filter mouthpiece of this utility model has an axial planar portion on the side wall of the cylindrical filter element, and the pattern display position is disposed on the planar portion.

[0009] The filter mouthpiece of this utility model has two planar portions that are radially opposite each other.

[0010] In the filter mouthpiece of this utility model, when assembled in place, the outer wall of the cylindrical filter element fits against the inner wall of the positioning groove.

[0011] The filter mouthpiece of this utility model has a suction mouthpiece at the rear end of the tube body, the internal channel of the suction mouthpiece is flat, and the outlet end of the suction mouthpiece has multiple air outlets along the width direction of its internal channel.

[0012] The filter mouthpiece of this utility model has a cavity on the front end face of the sealing plug, which forms the air outlet.

[0013] The air intake includes an air intake groove axially disposed on the peripheral sidewall of the sealing plug, and an air intake hole radially connected to the air outlet at the rear end of the bottom surface of the air intake groove.

[0014] The filter mouthpiece of this utility model has multiple air inlets that are evenly distributed circumferentially on the side wall of the sealing plug.

[0015] In the filter mouthpiece of this utility model, the air outlet end of the air inlet is located at the front end of the concave cavity.

[0016] The filter mouthpiece of this utility model has a plurality of annular steps with progressively larger diameters on the inner wall of the front end of the tube. The sealing plug is located in one of the annular steps closest to the cylindrical filter element. When assembled, the outer peripheral sidewall of the sealing plug fits against the axial sidewall of the annular step.

[0017] The beneficial effects of this utility model are as follows:

[0018] The overall structure is simple and the decorative effect is excellent.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] The preferred embodiment of the filter mouthpiece of this utility model, such as Figure 1-6As shown, the mouthpiece includes a tube 10, one end of which is a mouthpiece 11. The outer wall of the mouthpiece 11 is flat to improve user comfort. The other end of the tube 10 is a socket 12 for inserting a cigarette. When the cigarette filter is inserted into the socket 12, the user can inhale normally from the mouthpiece 11. The mouthpiece also includes a positioning groove 20 coaxially disposed on the inner wall of the tube 10, and a cylindrical filter element 30 disposed in the positioning groove 20. The side wall of the cylindrical filter element 30 is provided with a pattern display position, and the tube 10 is provided with a transparent part 101 corresponding to the pattern display position. Specifically, in order to reduce the number of parts and reduce the difficulty of processing... The mouthpiece is made of food-grade transparent plastic through a single injection molding process. It also includes a sealing plug 40 at the front end of the positioning groove 20, which seals the column filter element 30 within the groove 20. The sealing plug 40 has an air outlet 50 and an air inlet 60 connected to each other on its front outer wall and rear end face, respectively. This design features a simple overall structure and excellent decorative effect. The transparent part 101 allows the user to directly view the text or pattern on the display position of the column filter element 30. The overall functionality is richer, and the decorative effect is also stronger. Furthermore, the axial arrangement of the column filter element 30 provides further filtration.

[0032] In this embodiment, the side wall of the column filter element 30 is provided with an axial flat portion 70, and the pattern display position is provided on the flat portion 70. Specifically, there are two flat portions 70 that are radially opposite each other, so that the user can see the pattern or text on the column filter element 30 from two angles. Furthermore, when the column filter element 30 is assembled in place, the flat portion 70 of the outer side wall of the column filter element 30 is in contact with the inner wall of the positioning groove 20, so as to ensure that the airflow passes through the column filter element 30.

[0033] In this embodiment, the rear end of the tube body 10 is a suction nozzle 11. The internal channel 11a of the suction nozzle 11 is flat, that is, the cross-section is rectangular. The outlet end of the suction nozzle 11 has multiple air outlets 11b along the width direction of its internal channel 11a. Generally, there are two air outlets 11b. The inner diameter of the air outlet 11b is smaller than the thickness of the internal channel 11a of the suction nozzle 11.

[0034] In this embodiment, a cavity is provided on the front end face of the sealing plug 40, which forms an air outlet 50; further, the air inlet 60 includes an air inlet groove 61 axially disposed on the peripheral side wall of the sealing plug 40, and an air inlet hole 62 radially connected to the rear end of the bottom surface of the air inlet groove 61 to the air outlet 50. The air inlets 60 are provided in multiple and are evenly distributed circumferentially on the side wall of the sealing plug 40, so that the sealing plug 40 can still provide a flow channel for airflow after sealing the front end of the positioning groove 20.

[0035] In this embodiment, the air outlet end of the air inlet 62 is located at the front end of the concave cavity, so that multiple airflows entering the air outlet 50 are mixed to form a coaxial central airflow and enter directly from the front end of the column filter element 30.

[0036] In this embodiment, the inner wall of the front end of the tube 10 is provided with a plurality of annular steps 102 with progressively larger diameters. The sealing plug 40 is located in one of the annular steps 102 closest to the column filter element 30. When assembled, the outer peripheral sidewall of the sealing plug 40 and the axial sidewall of the corresponding annular step 102 fit together to isolate the positioning groove 20 from the external connection. The plurality of annular steps 102 can be adapted to cigarettes of different diameters.

[0037] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
