[0029] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0030] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0032] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0033] like Figures 1 to 4 As shown, this utility model embodiment provides a screw-type vacuum pump air intake filter device for cigarette equipment, including: a fixed housing 1, a circular mounting cylinder 2, a cleaning component 3, a driving component 4, and a sliding component 5.

[0034] A circular slot is provided on the side wall of the fixed housing 1, and the first end of the circular mounting cylinder 2 is connected to the circular slot.

[0035] The cleaning component 3, the driving component 4, and the sliding component 5 are all disposed inside the circular mounting cylinder 2. The cleaning component 3 includes a circular mounting plate 31, a plurality of first cleaning rods 32, and a plurality of second cleaning rods 33. The circular mounting plate 31 is disposed inside the circular mounting cylinder 2. The plurality of first cleaning rods 32 and the plurality of second cleaning rods 33 are respectively arranged in a circumferential manner on the circular mounting plate 31. The second cleaning rods 33 are located inside the first cleaning rods 32. The plurality of first cleaning rods 32 and the plurality of second cleaning rods 33 are used to insert into the filter holes 61 of the filter plate 6.

[0036] The drive assembly 4 is used to drive the circular mounting plate 31 to reciprocate within the circular mounting cylinder 2.

[0037] The sliding component 5 is used to limit the movement direction of the first cleaning rod 32 and the second cleaning rod 33.

[0038] When in use, first place the filter plate 6 at the second end of the circular mounting cylinder 2, and align the first cleaning rod 32 and the second cleaning rod 33 with the filter holes 61 of the filter plate 6.

[0039] Next, the drive assembly 4 is activated, which drives the circular mounting plate 31 to reciprocate within the circular mounting cylinder 2. This causes multiple first cleaning rods 32 and multiple second cleaning rods 33 to move back and forth within the filter holes 61 of the filter plate 6, thereby cleaning the dust within the filter holes 61 of the filter plate 6. This effectively cleans the dust from the filter holes 61 of the filter plate, improving the cleaning effect. Furthermore, the guiding action of the sliding assembly 5 further enhances the cleaning efficiency.

[0040] In one embodiment of the screw-type vacuum pump inlet filter device for cigarette equipment of this utility model, such as Figure 2 and Figure 3 As shown, the first end of the first cleaning rod 32 and the first end of the second cleaning rod 33 are both rotatably mounted on the circular mounting plate 31.

[0041] The cleaning assembly 3 also includes a first rotating wheel, a second rotating wheel, and a conveyor belt 34. The first rotating wheel and the second rotating wheel are respectively disposed at the second end of the first cleaning rod 32 and the second end of the second cleaning rod 33, and the conveyor belt 34 is sleeved on the first rotating wheel and the second rotating wheel.

[0042] Specifically, the number of first cleaning rods 32 is greater than the number of second cleaning rods 33, therefore, some of the first cleaning rods 32 are not fitted with the first rotating wheel.

[0043] This invention involves setting the first rotating wheel and the second rotating wheel at the second end of the first cleaning rod 32 and the second cleaning rod 33, respectively, and sleeve the conveyor belt 34 on the first rotating wheel and the second rotating wheel. This allows the first cleaning rod 32 and the second cleaning rod 33 to rotate slightly during their reciprocating movement within the filter holes 61 of the filter plate 6, thereby cleaning the inner cavity of the filter holes 61 of the filter plate 6 and achieving a better cleaning effect.

[0044] In one embodiment of the screw-type vacuum pump inlet filter device for cigarette equipment of this utility model, such as Figure 3 As shown, the sliding assembly 5 includes two first sliders 51 and two first grooves 52. The two first sliders 51 are respectively connected to the circular mounting plate 31, and the angle between the two first sliders 51 is 180 degrees.

[0045] Two first sliding grooves 52 are respectively opened on the opposite side walls of the inner cavity of the circular mounting cylinder 2, and two first sliders 51 are slidably connected to the two first sliding grooves 52 respectively.

[0046] This utility model connects two first sliders 51 to a circular mounting plate 31 respectively, and sets two first sliding grooves 52 on opposite side walls of the inner cavity of the circular mounting cylinder 2, thereby enabling the two first sliders 51 to slide in connection with the two first sliding grooves 52, thus ensuring the stability of the circular mounting plate 31 in the circular mounting cylinder 2.

[0047] In one embodiment of the screw-type vacuum pump inlet filter device for cigarette equipment of this utility model, such as Figure 3 and Figure 4As shown, the sliding assembly 5 also includes multiple inclined plates 53 and multiple fixed plates 54. The multiple inclined plates 53 are distributed along the circumference and are evenly spaced on the inner wall of the circular mounting cylinder 2. The first end of the fixed plate 54 is connected to the first cleaning rod 32, and the second end of the fixed plate 54 is slidably connected to the inclined plate 53.

[0048] Furthermore, the sliding assembly 5 also includes a plurality of second slide grooves 55 and a plurality of second sliders 56. The second slide grooves 55 are disposed on the inclined plate 53, and the second sliders 56 are disposed at the second end of the fixed plate 54, and the second sliders 56 are slidably disposed within the second slide grooves 55.

[0049] When the fixed plate 54 moves, it can squeeze the second slider 56 and make the second slider 56 move on the second slide groove 55, thereby driving the fixed plate 54 to rotate slightly, which in turn drives the first cleaning rod 32 to rotate slightly.

[0050] In one embodiment of the screw-type vacuum pump inlet filter device for cigarette equipment of this utility model, such as Figure 3 As shown, the drive assembly 4 includes a drive motor, a threaded sleeve 41, and a threaded rod 42. The drive motor is located at the center of the circular mounting cylinder 2. The threaded sleeve 41 is mounted on the circular mounting cylinder 2. The first end of the threaded rod passes through the threaded sleeve 41 and is connected to the output shaft of the drive motor. The threaded rod is threadedly connected to the threaded sleeve 41.

[0051] Specifically, the two first sliders 51 are respectively disposed on opposite sides of the threaded sleeve 41.

[0052] This invention improves cleaning efficiency and reduces the labor intensity of operators by placing the drive motor at the center of the circular mounting cylinder 2, setting the threaded sleeve 41 on the circular mounting cylinder 2, and threading the threaded rod 42 to the threaded sleeve 41. When the drive motor drives the threaded rod 42 to rotate, it can drive the threaded sleeve 41 to move back and forth inside the circular mounting cylinder 2.

[0053] In one embodiment of the screw-type vacuum pump air intake filter device for cigarette equipment of this utility model, the drive assembly 4 further includes a fan blade 43. The fan blade 43 is disposed at the second end of the threaded rod 42. When the threaded rod 42 is driven to rotate by the drive motor, the fan blade 43 can be driven to rotate, thereby blowing external air from the circular mounting cylinder 2 into the inner cavity of the fixed housing 1.

[0054] Furthermore, a ventilation opening 11 is provided on the side wall of the fixed housing 1. The ventilation opening 11 is arranged opposite to the circular slot. This arrangement can ensure the ventilation effect.

[0055] The implementation principle of the screw vacuum pump inlet filter device in this embodiment is as follows: Figures 1 to 4 As shown, the filter plate 6 is first placed at the second end of the circular mounting cylinder 2, and the first cleaning rod 32 and the second cleaning rod 33 are aligned with the filter holes 61 of the filter plate 6.

[0056] Next, the staff starts the drive motor. When the drive motor runs, it drives the threaded rod 42 to rotate. When the threaded rod 42 rotates, it drives the fan blade 43 to rotate. Therefore, the fan blade 43 can blow external air from the circular mounting cylinder 2 into the inner cavity of the fixed housing 1. When the threaded rod 42 rotates, it can drive the threaded sleeve 41, which is engaged, to move back and forth horizontally with the assistance of the first sliding groove 52 and the first slider 51. When the threaded sleeve 41 moves back and forth, it can drive the circular mounting plate 31 to move back and forth.

[0057] When the circular mounting plate 31 moves back and forth, it can drive the first cleaning rod 32 and the second cleaning rod 33 to move, thus allowing the first cleaning rod 32 and the second cleaning rod 33 to move back and forth on the filter plate 6, thereby cleaning the dust in the filter holes 61 of the filter plate 6.

[0058] When the first cleaning rod 32 moves, it can drive the fixed plate 54 to move back and forth. When the fixed plate 54 moves, it can squeeze the second slider 56 to move on the second slide groove 55, thereby driving the fixed plate 54 to rotate slightly, which can drive the first cleaning rod 32 to rotate slightly. When the first cleaning rod 32 rotates slightly, it can drive the second cleaning rod 33 to rotate from the conveyor belt 34, thereby cleaning the inner cavity of the filter hole 61 at the filter plate 6 and improving the cleaning effect.

[0059] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
