[0016] As a preferred technical solution of the present invention, a rubber friction plate is provided on each of the driving rods.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, the push rod is slidably displaced in the body by pressing the pressing plate, and the push rod drives the U-shaped frame to move toward the direction close to the plug cap assembly. During this process, the propulsion assembly, the guide assembly, the spray assembly and the plug cap assembly act on the columnar sharps at the same time: the spray assembly sprays disinfectant on the columnar sharps; the propulsion assembly pushes the columnar sharps forward so that the tip is covered with a cap and then continues to move forward to break away from the support of the bottom rod; the guide assembly drives the support plate away from the columnar sharps to release the bottom support, and the guide assembly drives the support plate and the two driving rods to move to both sides respectively to drive the columnar sharps to rotate and fully receive spraying and disinfection; finally, the columnar sharps are fully disinfected and the tip is covered with a cap and then automatically fall into the diversion assembly; the automatic reciprocating rotation of the diversion assembly realizes uniform storage, and the fallen columnar sharps are guided and grouped so that they are evenly distributed on both sides of the storage barrel in a horizontal state;

[0019] The various components of this device work together with a purely mechanical structure design. It can complete the entire process of disinfection, capping and orderly storage of medical waste sharps without the need for an external power source. While evenly disinfecting discarded cylindrical sharps, the tips are automatically capped to prevent cylindrical sharps from scratching human skin and reducing safety hazards. It fully disinfects, reduces the risk of virus transmission, and further reduces safety hazards. The cylindrical sharps are placed in the storage barrel and arranged in an orderly manner, saving storage space and facilitating subsequent processing by staff.

[0020] 2. The two ends of the U-shaped frame of the propulsion assembly of the present invention are connected to a sliding sleeve respectively, and the sliding sleeves on the same side are fixedly connected by a connecting rod. The end of the U-shaped frame away from the sliding sleeve is connected to a push rod, and the push rod passes through the body and is fixedly connected to the external pressure plate; the two driving rods are respectively fixed to the opposite ends of the sliding rods on both sides of the U-shaped frame, and are arranged in an upper and lower distribution; at a position close to the plug cap assembly, the bottom ends of the two sliding rods are respectively provided with a bottom bracket, each bottom bracket includes two spaced and fixed support plates, and the support plates on both sides of the columnar sharp device are installed in a staggered manner;

[0021] When the pressure plate is pushed, the U-shaped frame is moved by the push rod, which in turn drives the sliding rods on both sides to move outward and forward; the driving rod contacts the circumferential edge of the tail of the cylindrical sharp object, and forms an upward and downward reverse traction force on the tail of the cylindrical sharp object during the back-to-back movement, causing it to rotate; this rotation is beneficial to the installation of the cap and also facilitates the uniform spraying of the disinfectant. The whole process achieves the dual purposes of quickly installing the cap and fully disinfecting.

[0022] 3. The guide assembly of the present invention adopts a double-sided double guide unit structure. Each guide unit is composed of a fixed block and a guide plate symmetrical up and down. An arc-shaped guide groove is provided in the guide plate for the guide rod to slide. The two guide rods are connected by a slide rod. One side of the slide rod is connected to a T-block by a spring. The T-block can slide in the T-slot of the fixed block. When the pressure plate is pressed, the U-shaped frame drives the connecting sleeve and the connecting rod to move toward the plug cap assembly. Under the action of the guide rod and the arc-shaped guide groove, the slide rod slides in the slide sleeve and produces a composite radial and axial motion: radially away from the columnar sharp tool and axially close to the plug cap assembly. At the same time, the support plate at the bottom of the slide rod is radially away from the columnar sharp tool, and cooperates with the driving action of the tail drive rod to make the columnar sharp tool rotate forward and cover the cap, and finally separate from the bottom rod support together with the cap, and fall into the channel of the diversion assembly.

[0023] 4. The plug cap assembly of the present invention realizes the automatic capping function of the columnar sharp object through the coordinated cooperation of multiple structural components. After the cap is put into the cap feeding bucket, it enters the third channel through the downward inclined cap guide groove to form a cap reserve; two bottom rods are symmetrically arranged on both sides of the discharge port, and vertical rods are arranged on the bottom rods. The third channel is formed between the two vertical rods, and the fourth channel is formed between the two bottom rods. The torsion spring hinge arranged on the vertical rod is used to abut the cap. The torsion spring hinge is sleeved with a torsion spring on the pivot part to maintain the original state and realize rapid return. When the tip of the columnar sharp object extends into the interior of the cap, the cap is pushed to abut against the torsion spring hinge. After reaching the elastic threshold of the torsion spring hinge, the tip of the columnar sharp object and the cap squeeze the torsion spring hinge together and extend out of the vertical rod. The cap continues to move forward to leave the third channel and break away from the support of the bottom rod. After passing through the fourth channel, the tip of the columnar sharp object falls into the diversion assembly.

[0024] 5. The spray assembly of the present invention adopts a double-sided double-spray unit design, which is symmetrically distributed along the axis of the columnar sharp object. Each spray unit is fixedly connected to the reciprocating rod and the piston through a transmission rod, and the piston is installed inside the piston cylinder; two branches are provided at the bottom of the piston cylinder: one is connected to the nozzle through the first one-way valve, and the other is connected to the liquid storage tank through the second one-way valve. When the pressing plate is pressed, the U-shaped frame, the connecting sleeve, the connecting rod and the transmission rod move together toward the plug cap assembly, and the transmission rod pushes the piston to compress through the reciprocating rod. At this time, the second one-way valve is closed, the first one-way valve is opened, and the disinfectant in the piston cylinder is sprayed out through the first one-way valve and the nozzle; when the piston returns, the first one-way valve is closed, the second one-way valve is opened, and the disinfectant in the liquid storage tank enters the piston cylinder through the second one-way valve. The return of the piston and the reciprocating rod is realized by the spring in the guide unit. The spring reset drives the connecting rod to move, and then drives the transmission rod displacement to complete the return. Through this reciprocating motion, the spraying and disinfection of the columnar sharp object is completed.

[0025] 6. The diversion assembly of the present invention adopts a guide body design with a triangular tensile body structure, which is installed at the bottom of the first channel through a fixed axis; an arc groove is opened in the middle of the triangular bottom edge of the guide body to adjust the center of gravity, so that it has good rotation characteristics. When the columnar sharp object falls from the first channel, it first slides along the inclined surface of the guide body. Due to the special center of gravity design of the guide body, the gravity of the columnar sharp object acts on the side of the triangle to generate an eccentric force, driving the guide body to rotate around the fixed axis; during the rotation process, the triangular vertex of the guide body gradually turns to the other side, so that the current columnar sharp object falls through the second channel on one side while the second channel on the other side is open to receive the next columnar sharp object. Through this automatic reciprocating rotation mechanism, the alternating falling of the columnar sharp objects on both sides of the storage barrel is realized, and the automatic reciprocating rotation mechanism of the guide body realizes the uniform distribution of the columnar sharp objects on both sides of the storage barrel, effectively avoiding the problem of unilateral accumulation or inverted shelving of the tip; significantly improving the space utilization rate and reducing the risk of scratches; the entire diversion process is completely completed automatically by the mechanical structure, without the need for an additional power source, with a simple and reliable structure and low maintenance cost.

[0038] In the present invention, a sorting mechanism is arranged on the top of the storage barrel 11, and the sorting mechanism includes a body 12, a propulsion assembly, a guide assembly, a liquid spraying assembly, a plug cap assembly and a diversion assembly. The columnar sharp object 25 is placed in the inclined groove 13 on the body 12, and the columnar sharp object 25 enters the discharge port 14 downward along the inclined surface and falls into the propulsion assembly;

[0039] The inner wall of the discharge port 14 extends downward to the propulsion mechanism, and the inner wall size of the discharge port 14 is slightly larger than the size of the columnar sharp object 25, which is conducive to the columnar sharp object 25 sliding down onto the support plate 39. The tail of the columnar sharp object 25 is located at one end of the driving rod 29, and the pointed end of the columnar sharp object 25 is close to the cap 41.

[0040] like Figure 2 As shown in the figure, the side of the support plate 39 has an inner wall of the discharge port 14 (not shown in the figure) to ensure that the columnar sharp object 25 falls smoothly to the specified position.

[0041] When the device of the present invention is used, the pressing plate 17 is pressed to slide the push rod in the body 12, and the push rod drives the U-shaped frame 26 to move toward the plug cap assembly. During this process, the propulsion assembly, the guide assembly, the spray assembly and the plug cap assembly act on the columnar sharp tool 25 at the same time:

[0042] The spray assembly sprays disinfectant on the columnar sharp object 25; the propulsion assembly propels the columnar sharp object 25 forward so that its tip is covered with the cap 41 and then continues to move forward to break away from the support of the bottom rod 45; the guide assembly drives the support plate 39 away from the columnar sharp object 25 to release the bottom support, and the guide assembly drives the support plate 39 and the two driving rods 29 to move to both sides respectively to drive the columnar sharp object 25 to rotate and fully receive the spray disinfection;

[0043] Finally, the columnar sharps 25 are rotated and disinfected, and the tip is covered with a cap 41, then automatically falls into the diversion component; the diversion component guides the fallen columnar sharps 25 so that they are evenly distributed on both sides of the storage bucket 11 in a horizontal state; after the discarded columnar sharps 25 are evenly disinfected by the device, the tip is covered with a cap 41 to prevent the columnar sharps 25 from scratching human skin and reducing safety hazards; sufficient disinfection reduces the risk of virus transmission and further reduces safety hazards; the columnar sharps 25 are placed in the storage bucket 11 and arranged in an orderly manner to save storage space and facilitate handling by staff.

[0044] Furthermore, the guide assembly includes two groups of identically arranged guide units 38, the guide units 38 include a fixed block 34 and two guide plates 30 symmetrically arranged in the upper and lower parts, two guide grooves 31 are parallelly opened inside the guide plates 30, guide rods 32 are slidably installed in the guide grooves 31, the guide rods 32 are located in the upper and lower guide plates 30, and the two guide rods 32 are fixedly connected with a slide rod 37, the slide rod 37 is located between the upper and lower guide plates 30, and one end of the long side of the slide rod 37 is close to the columnar sharp tool 25; the side of the slide rod 37 away from the guide rod 32 is fixedly connected with a spring 33, and the other end of the spring 33 is fixedly connected with the spring 33. A T-block 36 is fixedly connected, and the T-block 36 is slidably installed in the T-slot 35 of the fixed block 34; a sliding sleeve 28 is slidably arranged on the sliding rod 37, and when the sliding sleeve 28 is subjected to an axial thrust along the columnar sharp object 25, the sliding rod 37 is driven to move radially away from the columnar sharp object 25, and the sliding rod 37 moves axially along the columnar sharp object 25 to approach the cap 41; further, the two groups of the guide units 38 are respectively distributed axially along one side of the columnar sharp object 25; the guide groove 31 is an arc groove, and the arc groove is opened axially along the columnar sharp object 25, and the arc groove is extended from one end adjacent to the spring 33 to the other end away from the columnar sharp object 25.

When the spring 33 is stretched, it automatically returns to its original position. Figure 3 Status in.

[0046] When the pressing plate 17 is pressed, the fixedly connected U-shaped frame 26, the connecting sleeve 28 and the connecting rod 27 move together in a direction close to the plug cap assembly, and at this time, the sliding rod 37 slides inside the sliding sleeve 28 and radially moves away from the columnar sharp tool 25, and the sliding rod 37 drives the guide rod 32 to move in the guide groove 31;

[0047] While the slide bar 37 moves away from the cylindrical sharp tool 25 in the radial direction, the slide bar 37 moves axially along the cylindrical sharp tool 25 to approach the plug cap assembly; during the sliding process of the guide rod 32 in the guide groove 31, the T-shaped block 36 is driven to slide inside the T-shaped groove 35, which is conducive to the smooth return of the guide rod 32;

The two ends of the U-shaped frame 26 are respectively fixedly connected to the sliding sleeve 28, and the two sliding sleeves 28 on the same side are fixed by the connecting rod 27; the end of the U-shaped frame 26 away from the sliding sleeve 28 is fixedly connected to the push rod, and the push rod passes through the body 12 and extends to the outside to be fixedly connected to the pressing plate 17; the driving rods 29 are respectively fixed on the opposite ends of the two sliding rods 37 adjacent to the U-shaped frame 26, and the two driving rods 29 are distributed up and down; when the pressing plate 17 is pushed to the U-shaped frame 26, the sliding rods 37 on both sides are driven to move to both sides and push forward, and the two driving rods 29 push the columnar sharp tool 25 while driving the driving rods 29 to rotate. Furthermore, the bottom ends of the two sliding rods 37 close to the plug cap assembly are respectively fixed with bottom brackets, and the bottom brackets include two support plates 39 fixed at intervals; the support plates 39 on both sides of the columnar sharp tool 25 are staggered.

[0053] Figure 3 and Figure 4 As shown in , the pressing plate 17 is located outside the body 12, and a push rod is fixedly connected to the pressing plate 17. The push rod passes through the side wall of the body 12 and is slidably installed. One end of the push rod away from the pressing plate 17 is fixedly connected to the U-shaped frame 26;

[0054] The two driving rods 29 are respectively fixedly connected to the ends of the sliding rods 37 on both sides. The two driving rods 29 are arranged at the upper and lower parts. The driving rods 29 are in contact with the circumferential edge of the tail of the columnar sharp object 25. In the process of the two driving rods 29 moving in opposite directions, the two driving rods 29 form reverse traction on the bottom of the columnar sharp object 25 along the circumferential tangent direction, so that the columnar sharp object 25 rotates. The rotating columnar sharp object 25 is easier to insert into the cap 41, and can also more fully receive the sprayed disinfectant, so that the cap 41 can be quickly put on and sufficient disinfection can be performed.

[0055] The two groups of guide units 38 close to the plug cap assembly are each provided with a support plate 39, and two support plates 39 are arranged at intervals on each group of guide units. The support plates 39 located on both sides of the columnar sharp object 25 are staggered, which is conducive to the extension of the support plates 39. The adjustable support length of the support plates 39 matches the installation time of the cap 41 to ensure that the front and rear synchronous falls of the columnar sharp object 25 into the diversion assembly.

[0056] Furthermore, the spray assembly includes two groups of spray units 54, and the two groups of spray units 54 are respectively distributed along the axial direction of one side of the columnar sharp device 25, and the spray unit 54 includes a transmission rod 46, a piston cylinder 48, a nozzle 49 and a liquid storage tank 22; the transmission rod 46 is fixed on the connecting rod 27, and the piston cylinder 48 is fixed on the inner wall of the main body 12. A reciprocating rod 47 is fixed on the transmission rod 46, and the other end of the reciprocating rod 47 is installed inside the piston cylinder 48 through a piston 51. Two branches are provided at the bottom of the piston cylinder 48, branch one is connected to the nozzle 49 after passing through a first one-way valve 52, and branch two is connected to the liquid storage tank 22 after passing through a second one-way valve 53; the first one-way valve 52 only allows flow from one end of the piston 51 to the nozzle 49, and the second one-way valve 53 only allows flow from one end of the liquid storage tank 22 to the piston 51.

[0057] Figure 1 and Figure 2 As shown in the figure, two liquid storage tanks 22 are symmetrically arranged in the body 12, and a liquid injection port 16 is arranged on the outer side of the body 12, and the liquid injection port 16 is connected to the liquid storage tank 22, and disinfectant is injected into the liquid storage tank 22; the liquid storage tank 22 is connected to the liquid inlet end 50 of the liquid spray unit 54 through the delivery pipe 23 to supply the liquid spray unit;

[0058] Figure 6 and Figure 7 As shown in the figure, when the pressing plate 17 is pressed, the fixedly connected U-shaped frame 26, the connecting sleeve 28, the connecting rod 27 and the transmission rod 46 move together in the direction close to the plug cap assembly, and the transmission rod 46 pushes the piston 51 through the reciprocating rod 47 to compress, and the disinfectant already in the piston cylinder 48 passes through the first one-way valve 52 and then sprays out through the nozzle 49; the space size of the piston cylinder 48 can be changed to store an appropriate amount of disinfectant, and the cylindrical sharp object 25 can be fully disinfected during the compression of the piston 51, providing sufficient disinfectant; the return of the piston 51 and the reset rod 47 is achieved by the spring 33 in the guide unit 38, and the reset of the spring 33 of the guide unit 33 drives the movement of the connecting rod 27, and the connecting rod 27 drives the transmission rod 47 to move, thereby realizing the return of the reciprocating rod 47 and the piston 51;

[0059] Working principle of the liquid spraying unit: when the transmission rod 46 pushes the piston 51 to compress through the reciprocating rod 47, the second one-way valve 53 is closed, and the first one-way valve 52 is opened, and the disinfectant in the piston cylinder 48 passes through the first one-way valve 52 and then is sprayed out through the nozzle 49;

[0060] When the transmission rod 46 pulls the piston 51 to retract through the reciprocating rod 47, the piston 51 returns to its original position through the reciprocating rod 47, and the piston 51 moves toward the transmission rod 46. At this time, the first one-way valve 52 is closed, and the second one-way valve 53 is opened, and the disinfectant passes through the second one-way valve 53 from the liquid inlet end 50 and enters the interior of the piston cylinder 48;

[0061] The piston cylinder 48 reciprocates as described above, and the nozzle 49 sprays and disinfects the columnar sharp object 25 .

[0062] Furthermore, the diversion component includes a guide body 20, a fixed shaft 21, a first channel 18 and a second channel 19, the first channel 18 and the second channel 19 are both opened in the inner wall of the main body 12, the first channel 18 is located below the columnar sharp object 25, and two second channels 19 are symmetrically arranged at the bottom of the first channel 18, and the two second channels 19 are forked. The guide body 20 is arranged at the bottom of the first channel 18 through the fixed shaft 21, and the fixed shaft 21 is installed on the inner wall of the main body 12, and the guide body 20 is rotatably installed on the fixed shaft 21.

[0063] Figure 2 , Figure 8 As shown in the figure, the guide body 20 is a triangular stretching body structure. When the guide body 20 rotates around the fixed axis 21, the top angle of the triangle abuts against the bottom inner wall of the first channel 18; an arc groove is opened in the middle of the bottom side of the triangle to change the center of gravity position of the guide body 20, which is beneficial to quickly tilt and adjust the position of the guide body 20 when it is squeezed.

[0064] The guide body 20 is a triangular tensile body structure, which is installed at the bottom of the first channel 18 through a fixed shaft 21. An arc groove is opened in the middle of the bottom side of the triangle to change the center of gravity. When the columnar sharp object 25 falls from the first channel 18, it first slides along the inclined surface of the guide body 20. Due to the center of gravity design, the guide body 20 is easy to rotate. The gravity of the columnar sharp object 25 acts on the side of the triangle to generate an eccentric force, driving the guide body 20 to rotate around the fixed shaft 21. The triangular vertex of the guide body 20 gradually turns to the other side, so that the current columnar sharp object 25 falls through the second channel 19 on one side while the second channel 19 on the other side is open to prepare to receive the next columnar sharp object 25. Through this automatic reciprocating rotation mechanism, the columnar sharp objects 25 are evenly distributed on both sides of the storage barrel 11, avoiding one-sided accumulation and improving space utilization.

[0065] Furthermore, the driving rods 29 are provided with rubber friction plates (not shown in the figures).

[0066] The rubber friction sheet can increase the friction force between the rubber friction sheet and the cylindrical sharp tool 25, which is beneficial to the rotation of the cylindrical sharp tool 25;

[0067] A rubber thread is provided on the top of one side support plate 39 to increase the friction between the tube body of the columnar sharp tool 25 and further facilitate the rotation of the columnar sharp tool 25;

[0068] The support plate 39 with the rubber thread is on the same side as the guide assembly of the lower driving rod 29, which is conducive to enhancing the friction in the same direction.

[0069] The rubber friction sheet is provided to increase the friction force to touch the rotation of the columnar sharp device 25, so as to more fully receive the spraying of the disinfectant and reduce the spread of the virus.

[0070] How it works

[0071] When the pressure plate 17 located outside the body 12 is pressed, the pressure plate 17 is transmitted to the U-shaped frame 26 through the push rod, driving the U-shaped frame to move toward the plug cap assembly. A sliding sleeve 28 is fixedly connected to each end of the U-shaped frame, and the two sliding sleeves 28 on the same side are fixedly connected by a connecting rod 27.

[0072] During the movement of the U-shaped frame 26, the transmission rod 46 fixed on the connecting rod 27 drives the reciprocating rod 47 to push the piston 51 for compression; when the piston is compressed, the second one-way valve 53 is closed, the first one-way valve 52 is opened, and the disinfectant in the piston cylinder 48 is sprayed out through the nozzle 49. When the piston 51 returns to its original position, the first one-way valve 52 is closed, the second one-way valve 53 is opened, and the disinfectant in the liquid storage tank 22 is replenished into the interior of the piston cylinder 48 through the delivery pipe 23.

[0073] At the same time, the guide unit 38 guides the guide rod 32 to slide through the guide groove 31 in the guide plate 30, and the slide rod 37 generates a composite radial and axial motion when sliding in the sleeve 28: radially away from the columnar sharp object 25, axially close to the plug cap assembly, and the support plate 39 at the bottom of the slide rod 37 moves radially away from the columnar sharp object 25, releasing the bottom support for the columnar sharp object; the spring 33 ensures that the guide assembly and the spray assembly can return to their original positions automatically.

[0074] The two driving rods 29 are respectively fixed to the opposite ends of the sliding rods 37 on both sides of the U-shaped frame 26, and are distributed up and down. The rubber friction sheet arranged on the driving rod 29 contacts the circumferential edge of the tail of the columnar sharp object 25, and forms an up and down reverse traction force on the tail of the columnar sharp object 25 during the back-to-back movement, so that it rotates; during the rotation of the columnar sharp object 25, its tip quickly enters the cap 41 to complete the sleeve connection and then pushes forward to detach from the cap 41, so that the cap 41 is detached from the support of the bottom rod 45, and the columnar sharp object 25 falls into the channel of the diversion component; in this process, the rotating columnar sharp object 25 can be more fully sprayed and disinfected by the disinfectant, which significantly improves the disinfection effect.

[0075] After disinfection and capping, the cylindrical sharp object 25 falls into the first channel 18. The guide body 20 arranged at the bottom of the first channel 18 is installed through the fixed shaft 21 and can rotate around it. The triangular structure of the guide body 20 guides the cylindrical sharp object 25 to fall alternately through the second channels 19 on both sides to achieve uniform distribution on both sides of the storage barrel 11; when a cylindrical sharp object falls through the second channel on one side, the guide body 20 gradually turns to the other side, so that the second channel on the other side is open to prepare to receive the next cylindrical sharp object.

[0076] During the whole process, all components work together: the disinfection spraying of the liquid spray component cooperates with the rotation of the cylindrical sharps to ensure uniform disinfection; the compound movement of the propulsion component and the guide component not only pushes the cylindrical sharps forward, but also drives them to rotate through the driving rod; the spacing design of the bottom rod 45 of the plug cap component ensures that the cap 41 can be reliably sleeved to provide a falling channel; the automatic reciprocating rotation of the diversion component realizes uniform storage. This purely mechanical structural design can complete the entire process of disinfection, capping and orderly storage of medical waste sharps without an external power source.

Those skilled in the art should understand that the relevant improvements to the present invention fall within the protection scope and disclosure scope of the present invention.
