Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0023] See also Figures 1 to 3 A tobacco leaf recovery and blowing device for a shredder includes a recovery body 10, a fan 20 and a vibrator 30. The recovery body 10 includes an air duct 12 and a recovery chamber 11. The fan 20 is arranged in the air duct 12. A filter element 13 is arranged in the recovery chamber 11. The air duct 12 is connected with the recovery chamber 11 through the filter element 13. A feed port 111 is arranged on the side wall of the recovery chamber 11. A discharge port 112 is arranged at the bottom of the recovery chamber 11. A vibrator 30 is arranged in the air duct 12. The vibrator 30 contacts the filter element 13. An air inlet 31 and an air outlet 32 ​​are arranged on the vibrator 30. Compressed air is passed through the air inlet 31. The vibrator 30 is vibrated by the compressed air. The fan 20 is started and stopped intermittently. When the fan 20 is started, the recovery chamber 11 absorbs the tobacco fragments, which are sucked into the recovery chamber 11 from the feed port 111 and collected in the recovery chamber 11 after being stopped by the filter element 13. When the fan 20 is stopped, the recovery chamber 11 stops absorbing the tobacco fragments, which fall down and are discharged through the discharge port 112. After being uniformly treated, they are mixed with shredded tobacco and processed into shredded tobacco.

[0024] The present application forms a negative pressure environment through suction by the fan 20 to collect smoke fragments, in order to prevent the smoke fragments from entering the fan 20 during the suction process of the fan 20 and affecting the normal operation of the fan 20. The recovery body 10 is set in two layers, including an air duct 12 and a recovery chamber 11 arranged above and below. The fan 20 is arranged in the air duct 12, and a filter element 13 is arranged in the recovery chamber 11. The air duct 12 and the recovery chamber 11 are connected through the filter element 13, and a feed port 111 is arranged on the side wall of the recovery chamber 11. When the fan 20 is started, a negative pressure environment is formed in the recovery chamber 11, and the smoke fragments are sucked into the recovery chamber 11 from the feed port 111. After being stopped by the filter element 13, the internal gas of the recovery body 10 enters the air duct 12 through the filter element 13, and the smoke fragments are uniformly collected in the recovery chamber 11.

[0025] In this embodiment, the recovery body 10 is cylindrical, the air duct 12 is located above the recovery chamber 11, and the air duct 12 is separated from the recovery chamber 11 by a partition. The filter element 13 is a candle-type filter element 13, and the filter element 13 is vertically arranged, and its top is arranged on the partition. The holes on the circumferential surface of the filter element 13 and the top of the filter element 13 can connect the recovery chamber 11 and the air duct 12, so that the gas flows from the recovery chamber 11 to the air duct 12.

[0026] Taking into account that after long-term use, too much cigarette fragments will adhere to the filter element 13, resulting in the inability of the gas inside the recovery body 10 to circulate smoothly and the negative pressure in the recovery chamber 11 to decrease, thereby causing the recovery body 10 to be unable to absorb the cigarette fragments, a vibrator 30 is also provided in the recovery body 10 to vibrate the filter element 13. The cigarette fragments absorbed on the filter element 13 are caused to fall off by vibration, thereby improving the gas circulation in the recovery body 10.

[0027] The vibrator 30 is in contact with and fitted to the filter element 13. Specifically, the vibrator 30 is arranged in the air duct 12 and on the partition, and in contact with the top of the filter element 13. In the present application, the vibrator 30 is a gas vibrator 30, and an air inlet 31 and an air outlet 32 ​​are arranged on the vibrator 30. The air inlet 31 is passed with compressed air. The compressed air enters the vibrator 30 to vibrate the vibrator 30, and the vibrator 30 contacts the filter element 13, thereby driving the filter element 13 to vibrate, so that the smoke adsorbed on the holes of the filter element 13 falls off, thereby increasing the gas flowability of the filter element 13 and improving the adsorption effect of the recovery chamber 11.

[0028] Furthermore, a pressure sensor 121 is provided in the air duct 12, and the pressure sensor 121 is provided above the filter element 13 to detect the pressure value in the air duct 12. The pressure value can be used to determine whether the filter element 13 is blocked, and then the pressure value can be used to determine whether to start the vibrator 30 to clean the filter element 13 from smoke fragments.

[0029] When the fan 20 is starting up, if the pressure sensor 121 detects that the pressure value is too low, the fan 20 stops and the vibrator 30 starts up. The vibrator 30 drives the filter element 13 to vibrate, causing the smoke adsorbed on the filter element 13 to fall off, thereby improving the gas flowability in the filter element 13.

[0030] A discharge port 112 is provided at the bottom of the recovery chamber 11 to discharge the tobacco scraps collected in the recovery chamber 11. A gate 14 is provided at the discharge port 112, and one side of the gate 14 is rotatably connected to the recovery chamber 11. When the gate 14 rotates to cover the discharge port 112, the discharge port 112 is in a closed state, and the tobacco scraps are collected in the recovery chamber 11; when the gate 14 rotates to expose the discharge port 112, the discharge port 112 is in an open state, and the tobacco scraps can be discharged through the discharge port 112. The discharged tobacco scraps are uniformly processed and mixed with shredded tobacco to enter the shredding process.

[0031] Preferably, a counterweight block is provided on the gate plate 14. When the fan 20 is not started, the gate plate 14 can open the discharge port 112 for discharge under the action of the counterweight block and its own gravity; and the power of the fan 20 should be sufficient. When the fan 20 is started, the adsorption force generated by the suction of the fan 20 can adsorb the gate plate 14 and the counterweight block thereon to stably cover the discharge port 112, so as to close the bottom of the recovery chamber 11 and keep the negative pressure state inside the recovery chamber 11 stable.

[0032] The specific recovery process is as follows: the fan 20 is started, and under the adsorption action of the fan 20, the gate plate 14 rotates to close the discharge port 112, and the recovery chamber 11 is in a negative pressure environment. The smoke fragments are sucked into the recovery chamber 11 from the feed port 111, and the filter element 13 stops the smoke fragments, and the smoke fragments are collected in the recovery chamber 11; the fan 20 stops, and the gate plate 14 that has lost its adsorption effect rotates under the action of the counterweight block and its own gravity to open the discharge port 112. Since the fan 20 stops, the negative pressure environment in the recovery chamber 11 changes and no longer has an adsorption effect. The smoke fragments adsorbed on the outer surface of the filter element 13 fall down, and are discharged through the discharge port 112 for unified treatment.

[0033] Considering that when a large amount of smoke fragments fall, the smoke fragments may block the discharge port 112, resulting in the gate 14 being unable to rotate into place when the reduction port is closed next time, further, a position sensor 15 is provided at the discharge port 112 to detect the position of the gate 14.

[0034] Preferably, a cleaning pipe 34 is also provided, one end of which is connected to the air outlet 32 ​​and the other end is arranged toward the discharge port 112. The compressed air used in the operation of the vibrator 30 can be used as an air source for cleaning, without the need to connect an external air source, thereby simplifying the overall structure.

[0035] In this embodiment, the position sensor 15 is an induction switch. When the position sensor 15 detects that the gate plate 14 is not rotated into place, the vibrator 30 is started, and the vibrator 30 drives the filter element 13 to vibrate, so as to clean the smoke debris attached to the filter element 13. The end of the cleaning pipe 34 cleans and blows the discharge port 112 to solve the problem of blockage of the discharge port 112.

[0036] Furthermore, a pressure regulating valve 33 is provided on the purge pipe 34 to control the purge pressure of the purge pipe 34 to avoid the problem of smoke fragments splashing and dispersing at the discharge port 112 due to excessive purge pressure of the purge pipe 34 .

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
