Description

Technical Field

[0001] The present invention relates to the technical field of medical care equipment, and in particular to an oral care device. Background Art

[0002] The cotton ball wiping method is a traditional oral care method in China. It uses a cotton ball soaked in care liquid to clean and moisten the face, mouth, tongue, teeth, etc. in a certain order.

[0003] The traditional cotton ball wiping method has some inconveniences, such as: manually soaking the cotton ball in the care solution, the amount of liquid absorbed by the cotton ball is difficult to control, the amount of care solution contained in the cotton ball is too high, resulting in dripping into it when wiping the patient's mouth, causing the patient to swallow the care solution; when the cotton ball is soaked in the care solution, the cotton thread falls into the care solution, affecting the subsequent use of the care solution. Patent CN116473707A discloses a quantitative control device for the content of mouthwash in cotton balls for oral care wiping, which is used to solve the above pain points. However, when using it, it is still necessary to replace the cotton ball through the clamping head, and the clamping head itself is stained with care solution. When the clamping head is inserted into the packaging bag to clamp the cotton ball, it will usually be stained with other cotton balls. In order to avoid contamination of unused cotton balls, it is necessary to manually take out multiple cotton balls and place them for clamping, which is inconvenient. Summary of the invention

[0045] See also Figures 1 to 14 This embodiment provides an oral care device, including a storage tube 10, a holding tube 30, two clamping arms 40, a separation mechanism 50 and a humidifying device 60.

[0046] The storage tube 10 is used to store cotton balls 20, and has an inlet end 11 for the cotton balls 20 to slide in, an outlet end 12 with an inwardly contracted mouth, and a clamping notch 13 extending in the axial direction is provided on both sides of the outer wall of the outlet end 12. Specifically, the inner diameter of the mouth of the outlet end 12 is smaller than the inner diameter of the storage tube 10, which can slightly restrict the cotton balls 20 in the storage tube 10, so that the cotton balls 20 will not easily slide out of the outlet end 12. The diameter of the cotton balls 20 is roughly similar to the diameter of the storage tube 10, and they can slide in the storage tube 10 under the action of gravity until they are restricted by the outlet end 12.

[0047] The gripping tube 30 is axially slidably sleeved on the storage tube 10. Specifically, an axial sliding groove is provided on the outer wall of the storage tube 10, and a slider slidably matched with the sliding groove is provided on the inner wall of the gripping tube 30, so that the gripping tube 30 can only slide axially on the storage tube 10.

[0048] The clamping arms 40 are elastic, and the two clamping arms 40 are symmetrical to each other. One end of the two clamping arms 40 is connected to the end of the holding tube 30, and the other ends of the two clamping arms 40 extend along the axial direction of the holding tube 30 and gradually approach each other and abut against each other, and can enter the clamping notch 13 to clamp the cotton ball 20. Specifically, the ends of the two clamping arms 40 away from the holding tube 30 gradually bend and approach each other and finally abut against each other.

[0049] The separation mechanism 50 is used to separate the ends of the two clamping arms 40 before the ends of the two clamping arms 40 enter the clamping notch 13. The ends of the two clamping arms 40 are close to each other again when entering the clamping notch 13. The separation mechanism 50 can be two electrically driven push rods arranged at the corresponding clamping arms 40 on the storage tube 10. When necessary, the push rods can abut against the corresponding clamping arms 40, thereby separating the abutting ends of the two clamping arms 40. The humidification device 60 uses the care solution to wet the cotton ball 20 located at the outlet end 12.

[0050] In this embodiment, when in use, a plurality of cotton balls 20 are placed inward from the inlet end 11 of the storage tube 10 in advance, and the storage tube 10 is placed upright. Under the action of gravity, the cotton balls 20 slide downward from the inlet end 11 to the outlet end 12 and are restrained by the outlet end 12. At this time, the gripping tube 30 is manually slid toward the inlet end 11 of the storage tube 10, and the two clamping arms 40 move with the gripping tube 30. The two clamping arms 40 correspond to the two clamping notches 13 respectively. When the two clamping arms 40 move away from the end of the holding tube 30 to the position of the clamping notch 13 and are about to enter the clamping notch 13, the separation mechanism 50 separates the ends of the two clamping arms 40 that are abutting against each other, and the ends of the two clamping arms 40 open to each other to prepare for clamping the cotton ball 20. After the holding tube 30 further slides toward the inlet end 11, the ends of the two clamping arms 40 pass through the separation mechanism 50 and, under the action of their own elastic force, enter the clamping notch 13 to clamp the cotton ball 20 at the outlet end 12 of the storage tube 10. At this time, the cotton ball 20 at this location is moistened by the humidifying device 60 using care solution. Then, the gripping tube 30 is withdrawn, that is, the gripping tube 30 is moved toward the outlet end 12 of the storage tube 10 again, and the ends of the two clamping arms 40 clamp the cotton ball 20 and give the cotton ball 20 a certain speed. After the cotton ball 20 passes through the outlet end 12 of the storage tube 10, it is still clamped by the ends of the two clamping arms 40, and the wiping action can be performed. Except for the clamped cotton ball 20, the remaining cotton balls 20 naturally move down to the outlet end 12 of the storage tube 10 under the action of gravity.

[0051] Multiple cotton balls 20 are moistened with care liquid by the humidifying device 60 in the storage tube 10, and the clamping arm 40 does not contact the care liquid, which can avoid the clamping arm 40 from contaminating the care liquid and other cotton balls 20. To clamp the cotton balls 20, you only need to slide the holding tube 30 back and forth, which is relatively convenient and fast.

[0052] In one embodiment, a first arcuate groove 14 extending in the circumferential direction is provided on the outer wall of the storage tube 10 corresponding to each clamping notch 13. One end of the first arcuate groove 14 is closed, and the other end of the first arcuate groove 14 is connected to the clamping notch 13.

[0053] The separation mechanism 50 includes two first arc-shaped blocks 51 and two elastic members 52 .

[0054] like Figure 1 , the two first arc blocks 51 are respectively arranged in the corresponding first arc grooves 14, and the ends of the first arc blocks 51 are slidably inserted from the first arc grooves 14 into the clamping notch 13 with the axis of the storage tube 10 as the center, and abut against the side walls of the clamping notch 13. Specifically, the first arc block 51 is arc-shaped as a whole, which matches the shape of the first arc groove 14, and the first arc groove 14 is provided with sliding grooves on the upper and lower sides, and the upper and lower ends of the first arc block 51 are respectively provided with arc-shaped protrusions that slide with the sliding grooves, so that the first arc block 51 can slide along the arc track in the first arc groove 14.

[0055] Two elastic members 52 are respectively disposed in the corresponding first arc grooves 14, one end of the elastic member 52 is connected to the end of the first arc groove 14 close to the clamping notch 13, and the other end is connected to the end of the first arc block 51 away from the clamping notch 13. Specifically, a groove is provided on the inner side of the first arc block 51, that is, on the side of the first arc block 51 facing the bottom of the first arc groove 14 to accommodate the elastic member 52.

[0056] The elastic member 52 is located between the first arc block 51 and the first arc groove 14, and is located in a groove formed on a side of the first arc block 51 facing the first arc groove 14. The elastic member 52 is in a tight state, so as to pull the first arc block 51 out of the first arc groove 14, so that the end of the first arc block 51 is inserted into the clamping notch 13 and abuts against the side wall of the clamping notch 13.

[0057] The end of the first arc block 51 inserted into the clamping notch 13 is inclined toward the side of the gripping tube 30, and the side of the end of the first arc block 51 inserted into the clamping notch 13 facing away from the gripping tube 30 is perpendicular to the inner wall of the clamping notch 13. Specifically, the interface of the end of the first arc block 51 inserted into the clamping notch 13 refers to the structure of the wedge block.

[0058] In this embodiment, Figure 1 , Figure 5 and Figure 6In the process of the gripping cylinder 30 driving the clamping arms 40 to rise, the lower ends of the two clamping arms 40 come to the two first arc blocks 51, and the lower ends of the two clamping arms 40 respectively abut against the first arc blocks 51 on the same side. The end face of the first arc block 51 at this place is the side of the end of the first arc block 51 away from the gripping cylinder 30, and the two clamping arms 40 are blocked by the ends of the two first arc blocks 51 and are separated. After the two clamping arms 40 pass the first arc block 51, under the action of their own elasticity, the ends of the two clamping arms 40 bounce into the clamping notch 13 and clamp the cotton balls 20 in the storage cylinder 10. Then the holding tube 30 moves downward, and the two clamping arms 40 move downward with it. The lower ends of the two clamping arms 40 clamp the cotton ball 20 and move outward from the outlet end 12 of the storage tube 10. At this time, the two clamping arms 40 will abut against the inclined surface of the end of the first arc block 51, and under the push of the clamping arms 40, the first arc block 51 retreats into the first arc groove 14, and the two clamping arms 40 can move from the clamping notch 13 to the outside of the storage tube 10, and the cotton ball 20 clamped by the two clamping arms 40 is used to wipe the patient.

[0059] In one embodiment, the oral care device further includes a fixing ring 70 and a first spring 71 .

[0060] The fixing ring 70 is sleeved outside the inlet end 11 of the storage tube 10. The first spring 71 is sleeved outside the storage tube 10, one end of the first spring 71 is connected to the fixing ring 70, and the other end of the first spring 71 is connected to the end of the holding tube 30 away from the clamping arm 40.

[0061] In this embodiment, when operating, the medical staff holds the gripping tube 30 and presses the storage tube 10 with the thumb, so that the storage tube 10 slides down in the gripping tube 30, and the gripping tube 30 moves up relative to the storage tube 10, so that the clamping arm 40 clamps the cotton ball 20, and at the same time, the first spring 71 is compressed. After the thumb no longer applies force, under the rebound effect of the first spring 71, the storage tube 10 slides up in the gripping tube 30, and the clamping arm 40 clamps the clamped cotton ball 20 out of the storage tube 10. The operation is relatively convenient and can be completed by the medical staff with one hand.

[0062] In one embodiment, one or more installation notches 15 extending in the axial direction are provided on the inlet end 11 of the storage tube 10 , and the bottom of the installation notch 15 is located at the outlet end 12 of the storage tube 10 ; a coaxial locking ring 72 is connected to the fixing ring 70 .

[0063] The humidifying device 60 includes one or more insert arms 61 , a circular positioning block 62 , a matching ring 64 , a locking ring 72 and a liquid injection mechanism 65 .

[0064] The insertion arm 61 can be inserted into the corresponding installation notch 15 by sliding along the axial direction of the storage tube 10. Figure 3The lower end of the insertion arm 61 can be inserted into the outlet end 12 of the storage tube 10 along the installation notch 15 .

[0065] The circular positioning block 62, whose outer peripheral wall is connected to the ends of all the insertion arms 61, can be inserted into the inlet end 11 of the storage tube 10. The size of the circular fixing block is relatively consistent with the size of the inner cavity of the storage tube 10. When the circular positioning block 62 is inserted into the inlet end 11 of the storage tube 10, the insertion arms 61 are inserted into the installation notch 15, so that the insertion arms 61 and the circular fixing block can only move along the axis of the circular fixing block.

[0066] The positioning rod 63 is coaxially fixedly connected to the circular positioning block 62. The inner ring of the matching ring 64 is connected to the positioning rod 63 through a bearing, and its outer wall can be threadedly connected to the inner wall of the locking ring 72. The injection mechanism 65 is connected to the end of the positioning rod 63 away from the circular positioning block 62.

[0067] The insert arm 61, the circular positioning block 62 and the positioning rod 63 are provided with a liquid injection channel 67. The inlet of the liquid injection channel 67 is connected to the liquid injection mechanism 65, and the outlet of the liquid injection channel 67 is located at one end of the insert arm 61 away from the circular positioning block 62 and facing the axis of the storage tube 10. The liquid injection mechanism 65 is used to inject the care solution into the liquid injection channel 67.

[0068] When in use, the insert arm 61 is inserted along the installation notch 15 until the circular positioning block 62 is inserted into the inlet end 11 of the storage tube 10. At this time, the lower end of the locking ring 72 just enters the upper end of the locking ring 72 from above, and the matching ring 64 can be rotated on the positioning rod 63. By rotating the matching ring 64, the matching ring 64 is threadedly connected with the locking ring 72, thereby fixing the fixed rod there. Since the fixed rod is connected to the circular positioning block 62, the fixed rod cannot rotate either and is completely locked. The injection channel 67 is arranged in each insert arm 61, the circular positioning block and the positioning rod 63, and is used to transport the care solution injected by the upper injection mechanism 65 to the end of the insert arm 61. The outer wall of the cotton ball 20 at the lower end of the insert arm 61 contacts the inner wall of the storage tube 10, and also contacts the outlet of the injection channel 67 of the insert arm 61. The cotton ball 20 can be moistened by the care solution flowing out of the injection channel 67 on the insert arm 61. Since more than one insert arm 61 may be provided, a plurality of insert arms 61 may be located around the cotton ball 20 , and the insert arms 61 around the cotton ball 20 may release care liquid to wet one cotton ball 20 at the same time.

[0069] In one embodiment, the injection mechanism 65 includes a piston 651 and a syringe 652 .

[0070] The piston 651 is connected to the fixed rod and has a through hole connected to the injection channel 67. The through hole on the piston 651 is coaxial with the fixed rod. One end of the injection cylinder 652 is closed ( Figure 8The other end is sleeved on the piston 651 and is dynamically sealed with the piston 651. Specifically, the piston 651 can be made of rubber material or hard material with reference to the structure of the syringe in the prior art. The dynamic seal is realized as follows: Figure 8 An annular groove is provided on the outer periphery of the piston 651 , an annular sealing ring is arranged in the groove, and the outer wall of the sealing ring abuts against the inner wall of the injection cylinder 652 .

[0071] In this embodiment, by pressing the syringe 652 downward, the care solution in the syringe 652 enters the injection channel 67 from the through hole of the piston 651, and the entire injection channel 67 and the internal space of the syringe 652 are connected as one. When the syringe 652 needs to be supplemented with care solution, the lower end of the insertion arm 61 is immersed in the care solution, and the syringe 652 is pulled to suck the care solution. A pull rope (not shown in the figure) is connected to the upper end of the syringe 652, and the pull rope is used to pull the syringe 652 to complete the suction of the care solution.

[0072] In one embodiment, the injection mechanism 65 further includes a mounting cylinder 653 , a magnetic limiting ring 654 , a driving cylinder 655 and a second spring 656 .

[0073] The installation tube 653 is coaxially sleeved outside the fixing rod, and one end is connected to the end of the matching ring 64 away from the circular positioning block 62. The outer wall of the magnetic limiting ring 654 is connected to the inner wall of the installation tube 653.

[0074] The driving cylinder 655 is coaxially arranged in the mounting cylinder 653, and its outer wall is gap-matched with the inner wall of the mounting cylinder 653. Its end can be moved to abut against the side of the magnetic limiting ring 654 away from the circular positioning block 62, and can be kept in the mounting cylinder 653. Specifically, the lower end of the driving cylinder 655 can be kept in the mounting cylinder 653 without being separated from the mounting cylinder 653.

[0075] The second spring 656 is sleeved outside the fixing rod, one end of the second spring 656 abuts against the circular positioning block 62 , and the other end of the second spring 656 abuts against the end of the driving cylinder 655 and is located inside the magnetic limiting ring 654 .

[0076] The outer wall of the injection cylinder 652 and the inner wall of the driving cylinder 655 are axially slidably matched; the outer wall of the injection cylinder 652 is provided with two rows of first ratchet blocks 659 arranged along its axial direction. The two rows of first ratchet blocks 659 are symmetrically arranged relative to the axis of the injection cylinder 652; a mounting seat 657 is rotatably provided at the inner wall of the driving cylinder 655 corresponding to the two rows of first ratchet blocks 659; the mounting seat 657 is rotatably connected to a driving arm 658; the end of the driving arm 658 away from the mounting seat 657 is connected to a second ratchet block 660 that fits with the first ratchet block 659; when the driving cylinder 655 is away from the circular positioning block 62, the inclined surface of the second ratchet block 660 slides along the inclined surface of the first ratchet block 659 and approaches the inner wall of the holding cylinder 30; the second ratchet block 660 can be magnetically attracted by the magnetic limiting ring 654.

[0077] In this embodiment, when the holding tube 30 is in a vertical state, the lower end surfaces of the second ratchet blocks 660 at the lower ends of the two driving arms 658 abut against the upper end plane of the first ratchet block 659 on the same side. When the holding tube 30 is tilted, since the two driving arms 658 are symmetrically arranged, the lower end of the driving arm 658 on one side swings against the inner wall of the holding tube 30 on the same side, and the second ratchet block 660 at the lower end of the driving arm 658 on the other side abuts against the first ratchet block 659 on the same side.

[0078] The medical staff presses the gripping cylinder 30 downward, and the second ratchet block 660 drives the first ratchet block 659 to move downward, thereby driving the injection cylinder 652 to move downward, pushing the care solution in the injection cylinder 652 into the injection channel 67, so that the cotton ball 20 at the outlet end 12 of the storage cylinder 10 is moistened. At this time, the driving cylinder 655 compresses the second spring 656 below, as shown in FIG. Figure 8 and Fig. 9 At this time, the driving cylinder 655 has compressed the second spring 656 , and the lower end of the driving cylinder 655 is against the magnetic limiting ring 654 .

[0079] Then, the medical staff stops pressing the drive cylinder 655, and the drive cylinder 655 gradually moves away from the circular positioning block 62 under the action of the second spring 656. At this time, the second ratchet block 660 on the drive arm 658 is separated from the first ratchet block 659 on the injection cylinder 652, and under the magnetic attraction of the magnetic limit ring 654, the second ratchet block 660 approaches the inner wall of the drive cylinder 655 on the same side, until the drive cylinder 655 moves away from the magnetic limit ring 654, and the magnetic attraction effect of the magnetic limit ring 654 on the second ratchet block 660 is weakened. When the second ratchet block 660 is suspended on the drive wall and passes through the first ratchet block 659, the upper end inclined surface of the second ratchet block 660 contacts the upper end inclined surface of the first ratchet block 659, and the second ratchet block 660 can move up along the inclined surface of the first ratchet block 659.

[0080] In this way, when the medical staff presses the driving cylinder 655 for multiple times and stops pressing, the injection cylinder 652 gradually approaches the circular positioning block 62, that is, the care solution in the injection cylinder 652 is injected from the injection channel 67 onto the cotton ball 20 one by one, and the care solution is pressed and injected onto a cotton ball 20 in cooperation with the clamping arm 40. The cotton ball 20 is then clamped out of the storage cylinder 10 by the clamping arm 40 for use, which is more convenient.

[0081] In one embodiment, the driving cylinder 655 includes a pressing cylinder 655a and a control ring 655b sleeved on the outer wall of one end of the pressing cylinder 655a. The control ring 655b can abut against the magnetic limiting ring 654. The second spring 656 abuts against the end of the pressing cylinder 655a.

[0082] The injection mechanism 65 also includes a control cylinder 661 and one or more extension pieces 662

[0083] The control cylinder 661 is threadedly sleeved on the outside of the installation cylinder 653 , that is, the control cylinder 661 is sleeved on the installation cylinder 653 , and the inner wall of the control cylinder 661 is threadedly connected with the outer wall of the installation cylinder 653 .

[0084] One end of the extension piece 662 is connected to the control cylinder 661, and the other end of the extension piece 662 bypasses the installation cylinder 653 and extends away from one end of the circular positioning block 62 to enter between the installation cylinder 653 and the pressing cylinder 655a, and can abut against the control ring 655b.

[0085] In this embodiment, the control cylinder 661 rotates on the mounting cylinder 653, so that the control cylinder 661 and the extension 662 move axially on the mounting cylinder 653, and the extension 662 limits the control ring 655b. Whenever the driving cylinder 655 moves upward for a certain distance, the control ring 655b abuts against the extension 662, and the driving cylinder 655 does not move upward any more. In other words, each time the driving cylinder 655 moves downward to push the injection cylinder 652 downward to complete the injection of the care solution onto the cotton ball 20, after the driving cylinder 655 moves upward, the second ratchet block 660 abuts against the first ratchet block 659 again, and the driving cylinder 655 is pressed downward again for the second injection. Due to the setting of the extension 662, the distance that the driving cylinder 655 moves upward each time is certain, so the distance that the driving cylinder 655 pushes the injection cylinder 652 downward each time is also certain, so that the amount of care solution injected by the injection cylinder 652 into the cotton ball 20 each time is certain, that is, quantitative control of the care solution. Moreover, the control cylinder 661 can rotate on the mounting cylinder 653, so that the distance that the driving cylinder 655 can move upward can be changed, so that the amount of care solution injected by the single injection cylinder 652 can be changed by the medical staff, and the operation is more convenient.

[0086] In one embodiment, the inserted arm 61 includes a first fitting section 611, a second connecting section 612 and a third fitting section 613 connected in sequence; the first fitting section 611 is connected to the circular positioning block 62; the cross-sectional area of ​​the second connecting section 612 is smaller than the cross-sectional area of ​​the first fitting section 611 and the cross-sectional area of ​​the third fitting section 613.

[0087] The oral care device further includes a guide ring 80 , a push block 81 and a release mechanism 82 .

[0088] The guide ring 80 is slidably mounted on the second connecting section 612. Figure 2 In the embodiment, there are two insertion arms 61, so there are also two guide rings 80, the push block 81 is located in the storage tube 10, the outer wall is connected to the two guide rings 80, and gravity is used to push the cotton ball 20 to move in the storage tube 10. The release mechanism 82 is used to limit the distance that the push block 81 falls by a diameter of a cotton ball 20 at a time under the action of gravity.

[0089] In this embodiment, the push block 81 and the guide ring 80 connected thereto can move up and down along the second connecting section 612, and each time the clamping arm 40 follows the gripping tube 30 to move up and down, the cotton balls 20 in the storage tube 10 are clamped out. When a cotton ball 20 is clamped out by the clamping arm 40, the push block 81 located above all the cotton balls 20 slides downward to push all the cotton balls 20 downward by the distance of one cotton ball 20, and then the push block 81 is restricted by the square mechanism and no longer moves downward. In addition, when in use, the cotton balls 20 are first loaded into the storage tube 10, and then the insertion arm 61 is inserted into the installation notch 15, and then the push block 81 is pressed on the top cotton ball 20, and the push block 81 can prevent the cotton ball 20 from sliding down due to friction with the inner wall of the storage tube 10. Since the cross-sections of the first fitting section 611 and the third fitting section 613 are larger than the second connecting section 612, the guide ring 80 can only move on the second connecting section 612 and cannot be separated from the second connecting section 612, that is, the guide ring 80 will resist the first fitting section 611 and the third fitting section 613 when moving upward or downward.

[0090] In one embodiment, a plurality of second arc grooves 16 are provided on the storage tube 10 corresponding to each mounting notch 15 and arranged along the length direction of the mounting notch 15. One end of each second arc groove 16 is connected to the mounting notch 15, and the other end of each second arc groove 16 extends along the circumference of the storage tube 10.

[0091] The release mechanism 82 includes a plurality of second arc blocks 821 , a plurality of first trigger blocks 822 , a plurality of third springs 823 and a plurality of second trigger blocks 824 .

[0092] A plurality of second arc blocks 821 are respectively disposed in the corresponding second arc grooves 16, and their ends are slidably inserted from the second arc grooves 16 into the installation notch 15 with the axis of the storage tube 10 as the center, and can abut against the guide ring 80. Specifically, the cross section of the second arc groove 16 is a combination of a circle and a square, and the second arc block 821 includes a curved columnar portion to slide with the second arc groove 16, and a shielding portion with a rectangular cross section, and the shielding portion is connected to the columnar portion.

[0093] The plurality of first trigger blocks 822 are arranged one by one with the plurality of second arc blocks 821, and each first trigger block 822 is connected to a side of the second arc block 821 away from the bottom of the second arc groove 16 and protrudes from the outer wall of the storage tube 10.

[0094] Multiple third springs 823 are arranged in one-to-one correspondence with multiple second arc blocks 821, one end of each third spring 823 is connected to the second arc block 821, and the other end of every third spring 823 is connected to the side wall of the second arc groove 16 away from the installation notch 15.

[0095] The plurality of second trigger blocks 824 are all connected to the inner wall of the holding tube 30, and the plurality of second trigger blocks 824 are arranged one by one corresponding to the plurality of first trigger blocks 822, and have an upper inclined surface and a lower inclined surface arranged obliquely;

[0096] The upper inclined surface and the lower inclined surface of the second trigger block 824 can both abut against the corresponding first trigger block 822 and drive the first trigger block 822 to move in two directions along the circumference of the storage tube 10 .

[0097] In this embodiment, Figure 2 There are a plurality of second arc blocks 821 from top to bottom, and the guide ring 80 connected to the push block 81 abuts against one of the second arc blocks 821, so that the push block 81 is limited.

[0098] When the holding tube 30 moves upward, the upper inclined surfaces of the multiple second trigger blocks 824 can resist against the first trigger block 822 and drive the second arc block 821 back into the third arc groove. At this time, the corresponding third spring 823 is compressed, and the guide ring 80 loses the restriction of the second arc block 821 and is driven downward by the pushing block 81.

[0099] As the holding tube 30 continues to move upward, after the second trigger block 824 passes the corresponding first trigger block 822, the second arc block 821 is quickly reset under the action of the third spring 823, and the guide ring 80 is restricted again, so that the pushing block 81 only drops the distance of a cotton ball 20 and then remains stationary again.

[0100] When the holding tube 30 moves downward, the lower inclined surface of the second trigger block 824 contacts the first trigger block 822 and only pushes the end of the second arc block 821 closer to the side wall of the installation notch 15, which will not break the limiting effect of the second arc block 821 on the guide ring 80.

[0101] Furthermore, the distance between the second trigger block 824 and the corresponding first trigger block 822 gradually increases from the outlet end 12 to the inlet end 11 of the storage cylinder 10. Specifically, Figure 2 and Fig.10 In the embodiment, the distance between the lower second trigger block 824 and the corresponding first trigger block 822 is smaller than the distance between the upper second trigger block 824 and the corresponding first trigger block 822 .

[0102] In this embodiment, when the holding tube 30 slides toward the inlet end 11 of the storage tube 10, the upper inclined surface of the second trigger block 824 at the bottom first abuts against the corresponding first trigger block 822, thereby compressing the corresponding second arc block 821 into the second arc groove 16. The second trigger block 824 at the top is one step later. When the arc block at the top retreats into the second arc groove 16, the guide ring 80 is released from the restriction. After the push block 81 moves down, the end of the second arc block 821 at the bottom has been reinserted into the installation notch 15, which can restrict the guide ring 80, so that the push block 81 can only move up and down the holding tube 30 once to the distance of the next cotton ball 20.
