[0001] The present invention relates to a purifier, and particularly to a portable bioaerosol purifier. Background Art

[0002] The spread and prevention and control of bioaerosols are still difficult problems faced by the prevention and control of infectious diseases at present. After biological particles enter the air, they will form bioaerosols that are secondarily dispersed with the air. For the health of people, it is necessary to purify bioaerosols. In traditional bioaerosol purifiers, people usually steal the prepared disinfectant into the purifier and then purify the bioaerosols. This purifier is easy to operate. However, due to the high cost of the prepared disinfectant, it is difficult for this purifier to reduce the purification cost of bioaerosols, and it is difficult to atomize the disinfectant, resulting in a reduction in the purification efficiency of bioaerosols.

Detailed implementation manners

[0031] The present invention will be further described below with reference to the embodiments shown in the drawings.

[0032] A portable bioaerosol purifier, as Figures 1 - 4 shown, includes a movable chassis 1, a liquid preparation barrel 11, a water injection pipe 12, a spraying head 13, a stirring mechanism 2 and a spraying mechanism 3. The upper part of the movable chassis 1 is connected with the liquid preparation barrel 11. The liquid preparation barrel 11 can prepare disinfectant solution. The upper right side of the liquid preparation barrel 11 is connected with the water injection pipe 12. The water injection pipe 12 can facilitate people to inject liquid into the liquid preparation barrel 11. The upper side of the liquid preparation barrel 11 is rotatably connected with the spraying head 13. The lower side of the spraying head 13 is communicated with the liquid preparation barrel 11. The spraying head 13 can spray the disinfectant solution. A stirring mechanism 2 for stirring the disinfectant solution is arranged on the movable chassis 1, and a spraying mechanism 3 for atomizing the disinfectant solution is arranged on the liquid preparation barrel 11.

[0033] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6 shown, the stirring mechanism 2 includes a motor 20, a rotating shaft 21, stirring rods 22 and a stirring impeller 23. The lower part of the movable chassis 1 is connected with the motor 20. The output shaft of the motor 20 is connected with the rotating shaft 21. The output shaft of the motor 20 rotates to drive the rotating shaft 21 to rotate. The upper part of the rotating shaft 21 passes through the lower part of the liquid preparation barrel 11. Three stirring rods 22 are uniformly connected to the outer wall of the upper part of the rotating shaft 21 along the circumferential direction. Stirring impellers 23 are rotatably connected to the stirring rods 22. The stirring impellers 23 can stir and mix the disinfectant solution.

[0034] As Figure 1 、 Figure 2 、 Figure 3 and Figure 7As shown in the figure, the spraying mechanism 3 includes an air delivery cylinder 30, a piston 31, a one-way valve 32, an air delivery pipe 33, and a spraying pipe 34. The lower left and right sides of the liquid preparation barrel 11 are both connected with the air delivery cylinder 30. The piston 31 is slidably connected to the air delivery cylinder 30. The upper side of the air delivery cylinder 30 is connected with the one-way valve 32. The one-way valve 32 enables the outside air to enter the air delivery cylinder 30, and at the same time can prevent the air in the air delivery cylinder 30 from being discharged to the outside. The upper side of the air delivery cylinder 30 is connected with the air delivery pipe 33. The air delivery pipe 33 can guide the air. The lower side of the spraying head 13 is connected with the spraying pipe 34, and the spraying pipe 34 is communicated with the air delivery pipe 33.

[0035] When people need to purify biological aerosol (referring to germs in the air, hereinafter referred to as air), this purifier can be used. First, people move this purifier to the position where purification is needed. Then, people add water and disinfection tablets into the liquid preparation barrel 11 from the water injection pipe 12. Subsequently, people start the motor 20. The output shaft of the motor 20 rotates to drive the rotating shaft 21 and the stirring rod 22 to rotate. The stirring rod 22 rotates to drive the stirring impeller 23 to rotate. In this way, the disinfection tablets and water can be stirred and mixed, so that disinfectant can be obtained. After the disinfectant is stirred, people pull the piston 31 downward, so that the air in the spraying head 13 enters the air delivery cylinder 30 through the air delivery pipe 33. At the same time, the disinfectant in the liquid preparation barrel 11 will enter the spraying pipe 34 and the spraying head 13. Then, people push the piston 31 upward. The upward movement of the piston 31 will make the air in the air delivery cylinder 30 enter the spraying head 13 through the air delivery pipe 33, and then make the disinfectant in the liquid preparation barrel 11 spray out through the spraying pipe 34 and the spraying head 13. In this way, the surrounding biological aerosol can be purified. After the biological aerosol is purified, people turn off the motor 20. By repeating the above operations, the disinfectant can be stirred and mixed by the stirring rod 22 and the stirring impeller 23. At the same time, the spraying pipe 34 can atomize the disinfectant, and then the sprayed disinfectant can be made more delicate, so that the purification area can be increased, and the purification efficiency of biological aerosol can be improved.

[0036] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 and Figure 9As shown, it also includes an alternating gas delivery mechanism 4 that enables the two piston rods 31 to move alternately. The alternating gas delivery mechanism 4 includes a rotating frame 40, a guide groove ring 41, a connecting column 42, a support member 43, a movable block 44 and a spring 45. The rotating frame 40 is connected to the lower part of the rotating shaft 21, and the guide groove ring 41 is connected to the rotating frame 40. The lower side of the piston 31 is connected to the connecting column 42, and the connecting column 42 is slidably connected to the guide groove ring 41. The guide groove ring 41 can guide the connecting column 42. The left and right sides of the spray pipe 34 are connected to the support members 43, and the movable blocks 44 are slidably connected to the support members 43. The movable blocks 44 can block the left and right sides of the spray pipe 34. Springs 45 are connected between the upper side of the movable block 44 and the support members 43, and the springs 45 can move and reset the movable block 44.

[0037] When people need to spray the disinfectant in atomization, first, when the rotating shaft 21 rotates, the rotating shaft 21 rotates to drive the rotating frame 40 and the guide groove ring 41 to rotate. The rotation of the guide groove ring 41 causes the connecting columns 42 and the piston 31 rods on the left and right sides to stagger and move up and down. At the same time, when the piston 31 rod on the right side moves upward, the upward movement of the piston 31 rod on the right side will squeeze the air in the air cylinder 30 on the right into the air pipe 33 on the right, and then the movable block 44 on the right side will move to the left under the action of the air. At this time, the spring 45 is compressed, and then the air in the air cylinder 30 on the right side can enter the spray pipe 34, so that the disinfectant can be sprayed out. The venom is atomized and sprayed out, and then when the piston 31 on the right moves downward, the movable block 44 on the right is released, and then the movable block 44 on the right moves to the right and resets under the action of the spring 45. At this time, the movable block 44 blocks the right side of the spray tube 34, and then the piston 31 on the right moves downward to draw the outside air into the air cylinder 30 through the one-way valve 32. The functional effect achieved by the movement of the left piston 31 is the same as that achieved by the movement of the right piston 31. Repeating the above operation and rotating the guide groove ring 41 can make the pistons 31 on the left and right sides move up and down alternately, thereby improving the bioaerosol purification efficiency.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 10As shown in the figure, it further includes a swing mechanism 5 that enables the spray head 13 to rotate automatically. The swing mechanism 5 includes a connecting member 50, a lifting rod 51, a groove block 52, a sliding member 53, a sliding frame 54, and a swing block 55. The rear side of the liquid preparation bucket 11 is slidably connected to the lifting rod 51. The lower side of the lifting rod 51 is connected to the connecting member 50. The connecting member 50 is slidably connected to the guiding groove ring 41. The upper side of the lifting rod 51 is connected to the groove block 52. The rear side of the spray head 13 is connected to the swing block 55. The upper rear side of the liquid preparation bucket 11 is connected to the sliding frame 54. The sliding frame 54 is slidably connected to the sliding member 53. The sliding frame 54 can guide the sliding member 53. The swing block 55 is rotatably and slidably connected to the upper part of the sliding member 53. The lower side of the sliding member 53 is rotatably and slidably connected to the groove block 52.

[0039] When people need to rotate the spray head 13, the rotation of the guiding groove ring 41 will cause the connecting member 50 to move up and down. The up and down movement of the connecting member 50 causes the lifting rod 51 to move up and down. The up and down movement of the lifting rod 51 causes the groove block 52 to move up and down, thereby causing the sliding member 53 and the swing block 55 to move left and right. The left and right movement of the swing block 55 can cause the spray head 13 to rotate left and right, thus increasing the purification area of the bioaerosol. Repeating the above operation and rotating the spray head 13 left and right can increase the purification area of the bioaerosol.

[0040] As Figure 1 , Figure 2 , Figure 3 , Figure 11 and Figure 12 As shown in the figure, it further includes a quantitative feeding mechanism 6 for quantitatively feeding disinfection tablets. The quantitative feeding mechanism 6 includes a mounting frame 60, a pushing member 61, a feeding pipe 62, and a disinfection tablet placement tank 63. The upper front side of the liquid preparation bucket 11 is connected to the mounting frame 60. The mounting frame 60 is slidably connected to the pushing member 61. The upper front side of the liquid preparation bucket 11 is connected to the feeding pipe 62. The upper side of the feeding pipe 62 is connected to the disinfection tablet placement tank 63. The disinfection tablet placement tank can place the disinfection tablets. The feeding pipe 62 can guide the disinfection tablets. The lower side of the feeding pipe 62 is connected to the mounting block.

[0041] When people need to prepare disinfectant liquid in the liquid preparation bucket 11, first, people inject clean water into the liquid preparation bucket 11. Then, people place the disinfection tablets in the disinfection tablet placement tank 63. Then, the disinfection tablets will fall into the pushing member 61 through the feeding pipe 62. Then, when the pushing member 61 is full of disinfection tablets, people push the pushing member 61 to the right, so that the disinfection tablets in the pushing member 61 fall into the liquid preparation bucket 11. At the same time, the pushing member 61 moves to the right, blocking the lower side of the feeding pipe 62, thereby stopping the falling of the disinfection tablets. When the addition of the disinfection tablets is completed, people pull the pushing member 61 to the left to reset. Repeating the above operation can quantitatively put the disinfection tablets into the liquid preparation bucket 11, thus preventing the inaccurate configuration ratio of the disinfectant liquid.

[0042] As Figure 1 , Figure 2 , Figure 3 , Figure 13 and Figure 14 shown, it further includes a prompting mechanism 7 for warning people. The prompting mechanism 7 includes an elastic member 70, connecting thin strings 71 and a metal tube 72. The elastic member 70 is clamped on the upper part of the spray head 13. Three connecting thin strings 71 are connected to both the left and right sides of the elastic member 70. The lower sides of the connecting thin strings 71 are all connected to the metal tube 72. The metal tube 72 will make a sound when vibrated, so as to be able to warn people. The metal tube 72 is hollow, which can make the sound emitted more crisp.

[0043] When the purifier purifies bioaerosols, the spray head 13 will make a sound. Then the sound vibration generated by the spray head 13 will be transmitted to the connecting thin strings 71 and the metal tube 72. Then the vibration of the metal tube 72 will make a sound, which can further prompt people. Since the metal tube 72 is hollow, the sound emitted can be made more crisp. By repeating the above operation and making a sound through the collision of the metal tube 72, people can be prompted, so as to be able to tell people not to approach this area and improve people's safety.

[0044] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
