[0024] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] refer to Figure 1 As shown, an embodiment of this application provides a cleaning structure 100, which includes at least two cleaning components 110, a rotating rod 120, and a driving component 130.

[0026] Specifically, in combination Figure 1 and Figure 2 As shown, two cleaning components 110 are respectively disposed on the inner and outer sides of the side wall 211 of the metering cylinder, and the two cleaning components 110 are arranged opposite to each other. The rotating rod 120 passes through the side wall 211 of the metering cylinder and is connected to the two cleaning components 110 respectively. The driving component 130 is rotatably connected to the end of the rotating rod 120 away from the cleaning component 110. The driving component 130 is located outside the metering cylinder. Correspondingly, the driving component 130 drives the cleaning components 110 to rotate through the rotating rod 120. The two cleaning components 110 can rotate simultaneously. The two cleaning components 110 clean the inner and outer sides of the side wall 211 of the metering cylinder respectively, so as to achieve the purpose of cleaning the inner and outer sides of the side wall 211 of the metering cylinder at the same time, ensuring cleaning efficiency, saving cleaning time, improving the cleaning effect of the metering cylinder, avoiding material adhesion to the side wall 211 of the metering cylinder and causing false detection during metering detection, preventing the impact on the metering detection accuracy of the metering cylinder, and ensuring the metering detection accuracy.

[0027] Understandably, in the tobacco production process, the metering tube 210 is used in conjunction with the elevator belt to control the flow rate of materials (such as tobacco shreds) and ensure the continuity and stability of the production process. Its working principle involves detecting the material accumulation height using a through-beam photoelectric detector. When the material accumulation is too high, the photoelectric detector sends a signal to stop the elevator belt. After the material is transported away, the signal is restored, and the elevator belt continues to run. However, during the descent, materials (such as tobacco powder) can easily adhere to the side wall 211 of the metering tube 210. This adhesion can cause false detections by the photoelectric detector, thus affecting material flow control and even causing material shortages, impacting production continuity.

[0028] refer to Figure 1 and Figure 2 As shown, the cleaning structure 100 has a first direction X. For example, the first direction X is taken as the width direction of the cleaning structure 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the parts in the cleaning structure 100 and should not be construed as limitations on this application.

[0029] In one embodiment, alternatively, referencing Figure 1 As shown, the two cleaning components 110 are a first cleaning component 111 and a second cleaning component 112. The second cleaning component 112 is fixedly connected to the end of the rotating rod 120 away from the driving component 130. The first cleaning component 111 is located between the second cleaning component 112 and the driving component 130, that is, the second cleaning component 112 corresponds to the inner side of the side wall 211 of the metering cylinder, and the first cleaning component 111 corresponds to the outer side of the side wall 211 of the metering cylinder. The first cleaning component 111 is fixedly connected to the rotating rod 120. The driving component 130 drives and simultaneously drives the first cleaning component and the second cleaning component 112 to move relative to each other.

[0030] In one embodiment, optionally, the cleaning component 110 is fixedly connected to the rotating rod 120 at its middle position, and the cleaning component 110 rotates relative to the rotating rod 120 as an axis. The cleaning area of ​​the cleaning component 110 is a circumferential range with the length of the cleaning component 110 as its diameter, so as to achieve the purpose of cleaning the side wall 211 surface of the measuring cylinder.

[0031] In summary, the driving component 130 of the cleaning structure 100 drives the cleaning component 110 to rotate via the rotating rod 120. The two cleaning components 110 can rotate simultaneously, and the two cleaning components 110 clean the inner and outer sides of the metering cylinder sidewall 211 respectively, achieving the purpose of cleaning both the inner and outer sides of the metering cylinder sidewall 211 at the same time, ensuring cleaning efficiency, saving cleaning time, improving the cleaning effect on the metering cylinder, avoiding material adhesion to the metering cylinder sidewall 211 and causing false detection during metering detection, preventing the impact on the metering detection accuracy of the metering cylinder, and ensuring the metering detection accuracy.

[0032] refer to Figure 1 As shown, an embodiment of this application provides another cleaning structure 100, which includes at least two cleaning components 110, a rotating rod 120, and a driving component 130.

[0033] Specifically, in combination Figure 1 and Figure 2 As shown, the two cleaning components 110 are respectively disposed on the inner and outer sides of the side wall 211 of the metering cylinder, and the two cleaning components 110 are disposed opposite to each other. The rotating rod 120 passes through the side wall 211 of the metering cylinder and is connected to the two cleaning components 110 respectively.

[0034] In this embodiment, the driving component 130 is rotatably connected to the end of the rotating rod 120 away from the cleaning component 110. The driving component 130 is located outside the metering cylinder. Correspondingly, the driving component 130 drives the cleaning component 110 to rotate through the rotating rod 120. The two cleaning components 110 can rotate simultaneously. The two cleaning components 110 clean the inner and outer sides of the side wall 211 of the metering cylinder, respectively, to achieve the purpose of cleaning the inner and outer sides of the side wall 211 of the metering cylinder at the same time, ensuring cleaning efficiency, saving cleaning time, improving the cleaning effect on the metering cylinder, avoiding material adhesion to the side wall 211 of the metering cylinder and causing false detection during metering detection, preventing the impact on the metering detection accuracy of the metering cylinder, and ensuring the metering detection accuracy.

[0035] In one embodiment, alternatively, referencing Figure 1 As shown, the two cleaning components 110 are the first cleaning component 111 and the second cleaning component 112, respectively. The second cleaning component 112 is fixedly connected to the end of the rotating rod 120 away from the driving component 130. The first cleaning component 111 is located between the second cleaning component 112 and the driving component 130. That is, the second cleaning component 112 corresponds to the inner side of the side wall 211 of the metering cylinder, and the first cleaning component 111 corresponds to the outer side of the side wall 211 of the metering cylinder. The first cleaning component 111 is fixedly connected to the rotating rod 120. The driving component 130 drives and simultaneously drives the first cleaning component and the second cleaning component 112 to move relative to each other.

[0036] In one embodiment, alternatively, such as Figure 1 As shown, there are four cleaning components 110. The four cleaning components 110 include two first cleaning components 111 and two second cleaning components 112. Each first cleaning component 111 corresponds to one second cleaning component 112. The two second cleaning components 112 are located inside the metering cylinder, and the two first cleaning components 111 are located outside the metering cylinder. The first cleaning components 111 are arranged one-to-one with the second cleaning components 112 to achieve the purpose of thoroughly cleaning the opposite side walls 211 of the metering cylinder, which has a better cleaning effect.

[0037] Optionally, the four cleaning components 110 are arranged sequentially along the first direction X, and the two side walls 211 of the metering cylinder are arranged opposite each other. That is, the four cleaning components 110 are arranged sequentially along the width direction of the cleaning structure 100, and the two side walls 211 of the metering cylinder correspond to each other. For example, the two side walls 211 of the metering cylinder are parallel to each other to facilitate detection by the photoelectric detector. The four cleaning components 110 are arranged linearly along the width direction of the cleaning structure 100 to achieve the purpose of cleaning the opposite side walls 211 of the metering cylinder.

[0038] Optionally, one drive member 130 corresponds to one first cleaning member 111 and one second cleaning member 112 via one rotating rod 120. The two rotating rods 120 are arranged in parallel, and the first cleaning member 111 and the second cleaning member 112 rotate relative to their respective rotating rods 120, thereby increasing the cleaning area of ​​the first cleaning member 111 and the second cleaning member 112, achieving better technical results. For example, the drive member 130 is a rotary cylinder, which drives the first cleaning member 111 and the second cleaning member 112 to rotate, achieving automatic cleaning.

[0039] In one embodiment, alternatively, referencing Figure 2 As shown, one end of the cleaning component 110 is fixedly connected to the rotating rod 120. The cleaning component 110 rotates relative to the rotating rod 120 as an axis. The cleaning area of ​​the cleaning component 110 is a circumferential range with the length of the cleaning component 110 as the radius, thereby achieving a large cleaning area.

[0040] In one embodiment, optionally, the cleaning component 110 is fixedly connected to the rotating rod 120 at its middle position, and the cleaning component 110 rotates relative to the rotating rod 120 as an axis. The cleaning area of ​​the cleaning component 110 is a circumferential range with the length of the cleaning component 110 as its diameter, so as to achieve the purpose of cleaning the side wall 211 surface of the measuring cylinder.

[0041] In one embodiment, the cleaning component 110 is optionally a cleaning brush. The brush head of the cleaning brush abuts against the side wall 211 of the metering cylinder. The cleaning brush abuts against the side wall 211 of the metering cylinder and cleans the side wall 211 of the metering cylinder, removing the smoke powder adhering to the side wall 211, avoiding false detection, and ensuring the accuracy of detection.

[0042] Optionally, the cleaning structure 100 further includes a solenoid valve 140, which is connected to the drive component 130. The solenoid valve 140 controls the opening and operation of the drive component 130 to automate the cleaning process. For example, the cleaning structure 100 also includes a sensor connected to the drive component 130. The sensor detects and provides feedback on the rotational position and angle to control the cleaning area and range.

[0043] refer to Figure 3 As shown, an embodiment of this utility model also provides a measuring device 200, including two photoelectric detection elements 220 arranged opposite each other, a transparent measuring tube 210, and a cleaning structure 100 as described in any of the above embodiments.

The measuring device 200 including the cleaning structure 100 has all the beneficial effects of the cleaning structure 100, which will not be described in detail here.

[0044] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0045] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
