[0007] Preferably, the body of the outer cylinder is in an arc shape, with a thick middle portion and thin ends of the outer cylinder.

[0008] Preferably, the support body further comprises an inner cylinder, the inner cylinder is arranged at the center of the outer cylinder, the lower end of the inner cylinder is fixed on the bottom surface of the outer cylinder, the side wall surface of the inner cylinder is evenly distributed with through holes, and the lower end of the inner cylinder is connected with the inner cavity of the filter cylinder; A second filter bag is arranged on the outer wall of the inner cylinder, the upper end of the second filter bag is fixed to the upper end of the inner cylinder, and the lower end of the second filter bag is connected to the bottom wall of the first filter bag.

[0025] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0026] Embodiment 1 like Figure 1-Figure 10 As shown, in this embodiment, a filter for oral liquid production is provided, including a filter cartridge 1, a cartridge cover 101 is provided at the upper end of the filter cartridge 1; a plurality of studs 9 are provided at the upper end of the filter cartridge 1, and a nut 10 for locking the cartridge cover 101 is engaged on each stud 9; a support body 2 is provided inside the filter cartridge 1, and the support body 2 includes an outer cartridge 201, and the outer cartridge 201 is rotatably connected to the inside of the filter cartridge 1, and a ring edge is provided at the upper end of the outer cartridge 201, and a shoulder 102 is provided inside the filter cartridge 1. When the outer cartridge 201 is placed inside the filter cartridge 1, the ring edge rests on the shoulder 102, and after the cartridge cover 101 is covered on the filter cartridge, a tightening ring 103 provided on the cartridge cover 101 is pressed on the ring edge, and at this time the ring edge can be on the shoulder 102 rotates between the outer cylinder 201 and the tightening ring 103. After the outer cylinder 201 is installed inside the filter cylinder 1, there is a gap between the outer wall of the outer cylinder 201 and the filter cylinder 1, and the side wall surface of the outer cylinder 201 is evenly distributed with through holes, and the upper end of the outer cylinder 201 is open; a first filter bag 3 is arranged inside the outer cylinder 201, and the first filter bag 3 is used to filter out impurities in the oral liquid; an upper ring plate 4 is fixedly connected to the upper end of the first filter bag 3, and the upper ring plate 4 is clamped on the upper end of the outer cylinder 201, so as to realize the connection of the upper end of the first filter bag 3 to the outer cylinder 201; a discharge port 104 and a filling port 105 are arranged on the side wall of the filter cylinder 1, the discharge port 104 is communicated with the inner cavity of the filter cylinder 1, and the filling port 105 is communicated with the inner cavity of the first filter bag 3.

[0027] A fixed clamping plate 7 is fixed to the bottom of the inner cavity of the outer cylinder 201, a rotating assembly 5 is arranged in the first filter bag 3, a movable clamping plate 6 for pressing the bottom wall of the first filter bag 3 onto the fixed clamping plate 7 is fixed to the bottom of the rotating assembly 5, a pin rod 8 is arranged on the rotating assembly 5, and a socket 701 for inserting the lower end of the pin rod 8 is opened on the side wall of the fixed clamping plate 7; When the first filter bag 3 is installed on the outer cylinder 201 through the upper ring plate 4, the movable clamping plate 6 and the fixed clamping plate 7, the first filter bag 3 is in a relaxed state.

[0028] The rotating assembly 5 includes: a central shaft 501, which is rotatably connected to the cylinder cover 101; a rotating frame 502 is fixedly installed at the lower end of the central shaft 501, and a pin rod 8 is slidably connected to the inside of the rotating frame 502; a motor 503 is installed above the cylinder cover 101, and the output shaft of the motor 503 drives the central shaft 501 to rotate.

[0029] The rotating assembly 5 further includes a lifting frame 504, which is disposed on the upper surface of the cylinder cover 101 and is used to support the motor 503 and control the lifting movement of the motor 503 on the cylinder cover 101; Fig. 9 As shown, the lifting frame 504 includes two oil cylinders, the cylinder bodies of the two oil cylinders are installed on the cylinder cover 101, and a lifting plate is fixedly installed on the output shaft of the oil cylinder. The motor 503 is fixed on the lifting plate. When the two oil cylinders are running, the lifting plate brings the motor 503 to lift on the cylinder cover 101, and the lifting movement direction is the same as the axial direction of the central shaft 501; the interior of the central shaft 501 is connected with a driving shaft 505 through a spline sleeve, and the upper end of the driving shaft 505 is fixedly connected to the output shaft of the motor 503. The driving shaft 505 and the central shaft 501 can keep synchronous rotation, and the driving shaft 505 can also slide axially in the central shaft 501; the lower end of the driving shaft 505 is fixedly connected to a pressing plate 506; the upper end of the pin 8 is fixedly connected to a slide plate 507; A spring 508 is provided between the pressing plate 506 and the sliding plate 507 , one end of the spring 508 is fixedly connected to the side wall of the pressing plate 506 , and the other end of the spring 508 is fixedly connected to the side wall of the sliding plate 507 .

[0030] The installation process of the first filter bag 3 is as follows: Open the cylinder cover 101, then place the outer cylinder 201 inside the filter cylinder 1, fix the movable clamping plate 6 inside the first filter bag 3, the movable clamping plate 6 and the first filter bag 3 can be fixed by bonding, and then install the movable clamping plate 6 on the rotating frame 502, then install the upper ring plate 4 on the shoulder 102, and cover the cylinder cover 101. During the process of covering the cylinder cover 101, the rotating frame 502 presses the movable clamping plate 6 into the filter cylinder 1, and then presses the first filter bag 3 into the interior of the filter cylinder 1. After the cylinder cover 101 is locked, the first filter bag 3 is installed in place, and the first filter bag 3 is in a relaxed state, as shown in FIG. Figure 3 As shown; The filtering process is: The lifting frame 504 drives the motor 503 to move downward. At this time, the driving shaft 505 drives the pressure plate 506 to slide downward inside the rotating frame 502, and then the pressure plate 506 presses the slide plate 507 downward through the spring 508, causing the slide plate 507 to slide downward with the pin rod 8, causing the lower end of the pin rod 8 to be inserted into the inside of the socket 701. In this state, the motor 503 is operated. At this time, the motor 503 drives the rotating frame 502 to rotate. During the rotation of the rotating frame 502, since the lower end of the pin rod 8 is inserted into the socket 701, the rotating frame 502 can rotate synchronously with the outer cylinder 201 and the first filter bag 3, and the first filter bag 3 is propped outward. Figure 4 As shown, the centrifugal force generated by the rotation will improve the efficiency of the oral liquid in the first filter bag 3 penetrating the first filter bag 3; After filtering for a period of time, the lifting frame 504 drives the motor 503 to move upward. At this time, the driving shaft 505 brings the pressure plate 506 to slide upward inside the rotating frame 502. At this time, the pressure plate 506 can pull the slide plate 507 and the pin rod 8 upward through the spring 508, causing the lower end of the pin rod 8 to be pulled out from the socket 701. In this state, the motor 503 is moved, so that the motor 503 drives the rotating frame 502 to rotate reciprocatingly through the driving shaft 505. Since the lower end of the pin rod 8 is pulled out from the socket 701, when the rotating frame 502 rotates, the rotating frame 502 first rotates with the movable clamping plate 6. At this time, the movable clamping plate 6 rotates with the lower end of the first filter bag 3, and then the first filter bag 3 body rotates through the upper ring plate 4 and the outer cylinder 201. Since the first filter bag 3 body transmits the rotating force and the first filter bag 3 itself is in a relaxed state, the first filter bag 3 will undergo a spiral distortion. Figure 5 As shown, the twisting amplitude is no more than half a circle. At this time, impurities attached to the inner wall of the first filter bag 3 can be squeezed out, thereby avoiding clogging of the first filter bag 3 and improving the filtering effect.

[0031] In addition, during the above-mentioned operation, the movable clamping plate 6 and the fixed clamping plate 7 rotate relative to each other, causing the lower end of the pin rod 8 to intersect with the socket 701. Since a spring 508 is set between the pressure plate 506 and the slide plate 507, when the pin rod 8 is inserted into the socket 701 again, the lifting frame 504 drives the motor 503 to move downward, and the driving shaft 505 and the pressure plate 506 move downward. At this time, the lower end of the pin rod 8 will abut against the upper surface of the fixed clamping plate 7, and the spring 508 is in a compressed state at this time. After rotating the rotating frame 502, the lower end of the pin rod 8 will slide on the upper surface of the fixed clamping plate 7. When the lower end of the pin rod 8 slides to align with the socket 701, the lower end of the pin rod 8 will be inserted into the socket 701 again through the pressure of the spring 508.

[0032] The body of the outer cylinder 201 is arc-shaped, and the middle part of the outer cylinder 201 is thick and the two ends are thin. When the outer cylinder 201 and the first filter bag 3 rotate, there is always a gap between the outer cylinder 201 and the first filter bag 3, which effectively prevents the first filter bag 3 from sticking to the side wall of the outer cylinder 201 and prevents some filter holes of the first filter bag 3 from being blocked, thereby improving the filtering effect.

[0033] Embodiment 2 like Figure 6-Figure 8 As shown, on the basis of the first embodiment, in order to further improve the filtering efficiency, the support body 2 of this embodiment further includes an inner cylinder 202, the inner cylinder 202 is arranged at the center of the outer cylinder 201, the lower end of the inner cylinder 202 is fixed on the bottom surface of the outer cylinder 201, the side wall surface of the inner cylinder 202 is evenly distributed with through holes, and the lower end of the inner cylinder 202 is connected with the inner cavity of the filter cylinder 1; A second filter bag 11 is arranged on the outer wall of the inner cylinder 202, the upper end of the second filter bag 11 is fixed to the upper end of the inner cylinder 202, and the lower end of the second filter bag 11 is connected to the bottom wall of the first filter bag 3. By adding the inner cylinder 202 and the second filter bag 11, after the oral liquid is filtered by the second filter bag 11, it flows directly into the interior of the filter cylinder 1 from the inner cylinder 202, thereby increasing the filtering area and improving the filtering efficiency.

[0034] After the second filter bag 11 is installed on the inner cylinder 202, the second filter bag 11 is also in a relaxed state, and its filtering and impurity removal process is synchronized with the first filter bag 3. The operating principle of the second filter bag 11 is the same as that of the first filter bag 3, so it is not repeated.

[0035] The body of the inner cylinder 202 is arc-shaped, and the middle part of the inner cylinder 202 is thin and the two ends are thick. There can always be a gap between the inner cylinder 202 and the second filter bag 11, which effectively prevents the second filter bag 11 from sticking to the side wall of the inner cylinder 202 and prevents some filter holes of the second filter bag 11 from being blocked, thereby improving the filtering effect.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
