[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] Embodiment 1

[0024] Referring to Figure 1 , Figure 2 , Figure 3 As shown, the present application discloses a ternary composite rod applicable to a cigarette filter tip, including a filter element part 1. An inner protection cylinder 11 is installed on the filter element part 1. A filter pipe 12 is sleeved inside the inner protection cylinder 11. A filter tip 14 is further installed at the head end of the inner protection cylinder 11. A ternary composite acetic acid filter element is arranged inside the filter pipe 12. An outer protection cylinder 2 is further sleeved on the inner protection cylinder 11 in a threaded manner. A connecting sleeve 21 is installed at the tail end of the outer protection cylinder 2. A rotating cylinder 3 is installed on the connecting sleeve 21. A smoke tube 31 for inserting a cigarette is installed at the tail end of the rotating cylinder 3. The tail end of the filter pipe 12 extends into the smoke tube 31 and a filter head 13 is installed;

[0025] Specifically, an inner protection cylinder 11 is arranged in the filter element part 1. Through the inner protection cylinder 11, it is convenient to install the outer protection cylinder 2 to cooperate with the connection of the rotating cylinder 3, so as to facilitate the insertion of a cigarette. The tail end of the filter pipe 12 extends into the smoke tube 31 and a filter head 13 is installed. After the cigarette is inserted into the smoke tube 31, it will abut against the filter head 13. Through the filter head 13 and the filter pipe 12, the smoke can be sucked. A ternary composite acetic acid filter element is further arranged in the filter pipe 12, which can filter out some harmful substances in the smoke and reduce the harm to the human body.

[0026] Referring to Figure 2 , Figure 3 As shown, a plurality of elastic pressing rods 131 are further arranged on the filter head 13 for pressing and fixing the cigarette. A clamping piece 132 is connected to the tail end of the elastic pressing rod 131. The head end of the elastic pressing rod 131 is concave and connected to the filter pipe 12. A lower pressing groove 133 is further opened at the part of the filter head 13 close to the elastic pressing rod 131. A plurality of helical tooth grooves 32 are further opened on the inner wall of the tail end of the rotating cylinder 3. The concave part at the head end of the elastic pressing rod 131 is matched with the side of the helical tooth groove 32;

[0027] Specifically, when driving the rotation of the rotating cylinder 3, the positions of the helical grooves 32 on the inner wall of the rotating cylinder 3 will change, and the side edges of the helical grooves 32 will change the contact parts with the elastic pressure rods 131, gradually squeezing the elastic pressure rods 131, thereby pushing the elastic pressure rods 131 to press tightly against the cigarettes to fix the cigarettes. In addition, in order to maintain the strength of the elastic pressure rods 131, the head ends of the elastic pressure rods 131 are provided with concavities. When the helical grooves 32 are in contact and cooperation with the concave parts of the elastic pressure rods 131, the elastic pressure rods 131 can be more easily pushed down, and the resilience performance of the elastic pressure rods 131 is ensured.

[0028] Referring to Figure 4 , Figure 5 , Figure 6 As shown, the inner diameter of the connecting sleeve 21 is adapted to the outer diameter of the filter tube 12, and a plurality of locking teeth 211 are inserted through the connecting sleeve 21. A stop head is further provided at the end of the locking teeth 211 close to the inner protective cylinder 11, and a trigger spring 212 is sleeved on the locking teeth 211. The trigger spring 212 is installed between the stop head of the locking teeth 211 and the connecting sleeve 21. An inner shrinkage groove 33 is further provided at the head end of the rotating cylinder 3. The diameter of the inner shrinkage groove 33 is adapted to the outer diameter of the connecting sleeve 21, and a plurality of tapered tooth grooves 332 are formed in the inner shrinkage groove 33. The locking teeth 211 are adapted to the tapered tooth grooves 332;

[0029] Specifically, ball grooves 331 are formed on both the outer surface of the connecting sleeve 21 and the inner surface of the inner shrinkage groove 33, and a plurality of bearing balls 213 are rotatably installed in the two ball grooves 331. The rotating cylinder 3 can be rotatably installed on the connecting sleeve 21 through the bearing balls 213. In addition, in order to keep the rotating cylinder 3 locked when the elastic pressure rod 131 presses the cigarette tightly, a plurality of locking teeth 211 are further provided on the connecting sleeve 21. When rotating the outer protective cylinder 2, the outer protective cylinder 2 can be gradually tightened on the inner protective cylinder 11, so that the connecting sleeve 21 gradually approaches the inner protective cylinder 11. When the inner protective cylinder 11 contacts the stop head at the end of the locking teeth 211, the locking teeth 211 can be squeezed, and the locking teeth 211 are pushed to slide and inserted into the tapered tooth grooves 332. At this time, since the connecting sleeve 21 has been abutted against the inner protective cylinder 11, the outer protective cylinder 2 cannot be tightened any further, and the rotating cylinder 3 which is engaged with the locking teeth 211 and the tapered tooth grooves 332 will also remain stationary and unable to rotate with the outer protective cylinder 2, and the helical grooves 32 will always press the elastic pressure rods 131 to keep the cigarettes fixed.

[0030] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, welding, etc. which are mature in the prior art. The machines, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.

[0031] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0032] The implementation principle of a ternary composite rod applicable to a cigarette filter tip in this application is as follows:

[0033] During use, first insert the cigarette into the cigarette tube 31. Then, the rotating cylinder 3 can be rotated. The helical tooth groove 32 inside the rotating cylinder 3 will rotate together, thereby changing the position where the helical tooth groove 32 contacts the elastic pressure rod 131. At this time, the elastic pressure rod 131 can be squeezed, so that the elastic pressure rod 131 presses the cigarette to fix the cigarette. The clamping piece 132 provided at the tail end of the elastic pressure rod 131 can increase the contact area with the cigarette to keep the cigarette stable. Then, the outer protective cylinder 2 can be pushed to tighten on the inner protective cylinder 11, so that the connecting sleeve 21 gradually approaches the inner protective cylinder 11. When the inner protective cylinder 11 contacts the stop head at the end of the locking tooth 211, the locking tooth 211 can be squeezed, and the locking tooth 211 is pushed to slide and inserted into the conical tooth groove 332. At this time, since the connecting sleeve 21 has been tightened against the inner protective cylinder 11, the outer protective cylinder 2 cannot be tightened anymore, and the rotating cylinder 3 that is engaged with the conical tooth groove 332 by the locking tooth 211 will also remain stationary and unable to rotate with the outer protective cylinder 2. The helical tooth groove 32 will always press the elastic pressure rod 131 to keep the cigarette fixed. The tail end of the filter tube 12 extends into the cigarette tube 31 and is provided with a filter head 13. After the cigarette is inserted into the cigarette tube 31, it will abut against the filter head 13. The smoke can be sucked through the filter head 13 and the filter tube 12. A ternary composite acetic acid filter element is also provided in the filter tube 12, which can filter out some harmful substances in the smoke and reduce the harm to the human body;

[0034] After loosening the outer protective cylinder 2, the trigger spring 212 is restored, so that the locking tooth 211 can be pulled out of the conical tooth groove 332. At this time, the restraint on the rotating cylinder 3 can be released, and due to the provided bearing balls 213, it is convenient to keep the rotating cylinder 3 and the connecting sleeve 21 rotatably connected. When the rotating cylinder 3 is pushed to rotate and reset, the elastic pressure rod 131 loses pressure and will expand and reset outward, releasing the fixation of the cigarette and facilitating the removal of the cigarette;

[0035] Moreover, in order to maintain the strength of the elastic pressure rod 131, a concave is provided at the head end of the elastic pressure rod 131. When the helical tooth groove 32 contacts and cooperates with the concave part of the elastic pressure rod 131, the elastic pressure rod 131 can be more easily pushed down, and the resilience performance of the elastic pressure rod 131 is ensured.

[0036] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model.
