[0021] The technical solution of the present utility model is further described below in conjunction with specific embodiments.

[0022] like Figure 1 As shown, the specific implementation of the utility model is: constructing a filter rod with a color-changing function, including a base rod 3 and a color-changing part 2 that changes color with temperature, the base rod 3 is formed of a flexible filter material into a rod shape that matches the cigarette, and the color change of the color of the color-changing part 2 can be seen on the surface of the base rod 3. The base rod 3 and the color-changing part 2 are connected and then connected to the cigarette 1. A smoke channel 21 for smoke to pass through is provided in the color-changing part 2, and the smoke of the cigarette 1 passes through the smoke channel 21 of the color-changing part 2.

[0023] like Figure 1 As shown, the specific implementation process of the present invention is as follows: the filter rod is the filter tip portion of the rear portion of a cigarette used for filtering inhalation. In this invention, the filter rod comprises a base rod 3 and a color-changing portion 2 that changes color with temperature. The base rod 3 is formed of a flexible filter material in a rod-like shape that fits the cigarette. The color-changing portion 2 changes color with temperature, and the color change is visible on the surface of the color-changing portion 2. The color-changing portion 2 is provided with a smoke passage 21 for smoke to pass through. Smoke from the cigarette 1 passes through the smoke passage 21 of the color-changing portion 2. After the cigarette burns, the user inhales the smoke, drawing it into the filter rod. The smoke passes through the smoke passage 21 of the color-changing portion 2. The color of the color-changing portion 2 heats up as the temperature of the passing smoke increases. As the temperature of the color-changing portion 2 increases, the color of the color-changing portion 2 changes. Conversely, if smoking stops and no smoke passes through, the temperature of the color-changing portion 2 decreases, and the color of the color-changing portion 2 also changes. The color-changing portion 2 is formed by adding temperature-changing powder to silica gel or aerosol. The temperature-changing powder is a microcapsule pigment that repeatedly changes color as the temperature rises and falls. A color-changing portion 2 that changes color can be formed by adding a certain proportion or a specified type of temperature-changing powder, or a color-changing portion 2 of a specified color can be formed. In a specific embodiment, one end of the color-changing portion 2 abuts against the cigarette, and the other end of the color-changing portion 2 is connected to the base rod 3. The base rod 3 is formed of one or more of an acetate fiber rod, a PET fiber rod, a PP fiber rod, and a PE fiber rod. In a specific embodiment: one end of the base rod abuts against the cigarette, and the other end of the base rod is connected to the color-changing portion.

[0024] like Figure 2 As shown, in a preferred embodiment of the present invention, the base rod includes a first base rod 31 and a second base rod 32, and the color-changing portion 2 is disposed between the first base rod 31 and the second base rod 32. One end of the first base rod 31 abuts against the cigarette and the other end is connected to the color-changing portion, while one end of the second base rod 32 is connected to the color-changing portion 2.

[0025] like Figure 3As shown, in a preferred embodiment of the present invention: the color-changing portion 2 includes a transparent substrate 22 arranged on the outside and a color-changing module 23 arranged in the transparent substrate, a smoke channel 21 is arranged in the color-changing module 23, and the smoke of the cigarette 1 passes through the smoke channel 21 of the color-changing portion 2.

[0026] In a preferred embodiment of the present invention, the color-changing portion 2 includes a functional module formed of a color-changing material, wherein the functional module is one or more of a filter, a loading chamber for liquid, or a mounting chamber for popping beads. The color-changing portion 2 can be made into a number of functional modules, such as a filter used on a cigarette, a loading chamber for liquid, or a mounting chamber for popping beads.

[0027] In a preferred embodiment of the present invention, the filter is a filter in any of the following shapes: spiral, pedal, microporous, and Venturi. Figure 4 As shown, the filter is in the shape of a pedal. Figure 5 As shown, the filter is in a Venturi shape. Figure 6 As shown, the filter is in a spiral shape.

[0028] In a preferred embodiment of the present invention, the color-changing portion forms a filter for filtering smoke, which can not only change color when filtering smoke, but also filter harmful substances in the smoke.

[0029] In a preferred embodiment of the present invention, the color changing portion forms a loading chamber for loading a humidifying and flavoring liquid. The loading chamber is loaded with the humidifying and flavoring liquid, which can achieve both color change during smoke filtering and humidification and flavoring during use.

[0030] In a preferred embodiment of the present invention, the color changing portion forms a mounting cavity for mounting a popping bead, wherein the popping bead is mounted in the mounting cavity, and when in use, the color can be changed when filtering smoke, and the popping bead can be pressed to increase fragrance.

[0031] The technical effect of the present invention is to construct a filter rod with a color-changing function, comprising a base rod 3 and a color-changing portion 2 that changes color with temperature. The base rod 3 is formed of a flexible filter material in a rod-shaped form that fits the cigarette. The color-changing portion 2 changes color visibly on its surface. The base rod 3 is connected to the color-changing portion 2 and then to the cigarette 1. The color-changing portion 2 is provided with a smoke passage 21 for smoke to pass through. Smoke from the cigarette 1 passes through the smoke passage 21 of the color-changing portion 2. The present invention provides a filter rod with a color-changing function. The color-changing portion 2 changes color with temperature. During the smoking process, smoke flows through the smoke passage of the color-changing portion 2. Since the smoke originates from the high-temperature burning cigarette, the smoke also has a certain temperature, causing the temperature of the color-changing portion 2 to rise. The color-changing portion 2 changes color when it encounters the temperature increase. The color change of the color-changing portion 2 allows the temperature of the filter rod to be better understood. As the cigarette burns closer, the temperature increases, and the color change becomes more obvious, which helps to provide a safe smoking reminder. At the same time, since you can intuitively feel the color changes during smoking, it also brings a certain amount of fun.

[0032] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
