[0002] Povidone-iodine solution (spray form) has a broad-spectrum bactericidal effect and can kill a variety of microorganisms such as bacteria, viruses, and fungi. After being made into a spray form, it can be used for disinfection of skin and mucous membranes through in vitro spraying. When in use, the pump body pumps the solution in the tank into the nozzle by pressing the nozzle and sprays it out through the nozzle. After the device is used, due to the small diameter of the nozzle outlet and the large amount supplied by the pump body, a small amount of solution will not be atomized in time after passing through the nozzle outlet and will remain outside the nozzle outlet. If the nozzle outlet is not wiped and cleaned in time, when the povidone-iodine solution is exposed to the air, the water in the solution will gradually evaporate, thereby increasing the concentration of the povidone-iodine solution, and the solution may become thicker and block the nozzle outlet.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 8 As shown, the present invention provides an anti-pollution medicine atomization spray device, comprising a cover assembly 1, the cover assembly 1 comprising a lower cover 11 mounted on the top of the tank body and an upper shell 12 fixedly connected to the middle of the lower cover 11, and further comprising: a spray head assembly 3, which is arranged on the lower cover 11;

[0032] The spray head assembly 3 includes a button 1 31 movably connected to the top of the lower cover 11, a button 2 32 is movably connected to the top of the button 1 31, and a straight groove 33 in an inclined state is symmetrically provided on the button 2 32. An elastic slider 34 is elastically supported in the button 1 31, and one end of the elastic slider 34 extends to the outside of the button 1 31. The elastic slider 34 is symmetrically fixed with protrusions 35 that can slide in two straight grooves 33 respectively, and an elastic telescopic rod 36 for supporting the button 1 31 is fixed between the bottom of the button 1 31 and the upper shell 12;

[0033] The cover assembly 1 is also provided with a pressure assembly 2 for unidirectionally pumping liquid medicine toward the elastic slider 34 during the pressing process of the button 1 31, and the bottom end of the pressure assembly 2 extends to the bottom of the tank body;

[0034] The elastic slider 34 is provided with a cavity 341, one end of the cavity 341 is fixedly connected to the atomizing nozzle body 342, the other end of the cavity 341 is movably sleeved and connected to a hard pipe 2 343, and the other end of the hard pipe 2 343 is fixedly connected to the output end at the top of the pressure assembly 2;

[0035] The pressure assembly 2 includes a cylinder 21 fixedly connected to the bottom of the upper shell 12, the bottom of the cylinder 21 is fixedly connected to a pipe 22, the bottom of the pipe 22 is fixedly connected to a pipe 24, the bottom of the cylinder 21 is also elastically supported by an elastic valve core 23 for blocking the pipe 22 downward in one direction, the button 31 is fixedly connected to a hard pipe 25 inside, the top of the hard pipe 25 is fixedly connected to the hard pipe 2 343, the bottom of the hard pipe 25 extends into the cylinder 21 and is connected thereto, the bottom of the hard pipe 25 is fixedly connected to a piston 27 movably connected to the cylinder 21, and the middle of the hard pipe 25 is elastically supported by an elastic valve core 26 for blocking the hard pipe 25 downward in one direction;

[0036] By adopting the above scheme, by installing the lower cover body 11 on the tank body, pressing the button 2 32 and forcing the elastic slider 34 to move toward the hard tube 2 343 through the straight groove 33, the hard tube 2 343 enters the cavity 341. When the elastic slider 34 is completely contracted to the inside of the button 1 31 except for the disc-shaped part, the elastic telescopic rod 36 is compressed when the button 1 31 moves downward. At this time, the button 1 31 causes the hard tube 1 25 and the piston 27 to move downward. At this time, the liquid medicine in the cylinder 21 will enter the hard tube 1 25, and push the elastic valve core 26 upward to release the seal of the hard tube 1 25 and then enter the hard tube 2 343.

[0037] When the button 32 is released, the button 31 is reset by the elastic force of the elastic telescopic rod 36, and the hard tube 25 and the piston 27 move upward. At this time, the hard tube 25 is sealed by the elastic valve core 26, so that the inside of the cylinder 21 is in a negative pressure state. At this time, the elastic valve core 23 will release the seal on the pipe 22, and the medicine inside the tank will enter the cylinder 21 through the pipe 24 and the elastic valve core 23 for storage. Then the elastic slider 34 is reset by its own elastic force. At this time, the space formed by the hard tube 343 and the cavity 341 increases, and the inside of the two is in a negative pressure state, so that the medicine remaining at the outlet of the atomizing nozzle body 342 will be sucked back into the inner cavity of the elastic slider 34 by the negative pressure inside the cavity 341 for storage, thereby avoiding the situation that the medicine will remain in the cavity 341 or the outlet of the atomizing nozzle body 342 and block both to affect the use.

[0038] like Figure 4 As shown, a through hole 122 is also provided at the bottom of the upper shell 12, the button 31 is clearance-matched with the upper shell 12, and the space of the cylinder 21 above the hard tube 25 is connected to the outside through the through hole 122;

[0039] By adopting the above solution and providing the through hole 122, when the hard tube 25 drives the piston 27 to move upward or downward, the pressure balance of the space above the hard tube 25 is ensured.

[0040] like Figure 1-Figure 3 As shown, a vertical groove 121 is formed on one side of the button 1 31; an end of the atomizing nozzle body 342 located outside the button 1 31 is in a round shape, and its round shape diameter is smaller than the width of the vertical groove 121, and the width of the elastic slider 34 is greater than the width of the vertical groove 121;

[0041] By adopting the above scheme, through the disc-shaped design of one end of the atomizing nozzle body 342, only when the button 2 32 moves downward through the straight groove 33 to force the boss 35 to drive the elastic slider 34 except the disc-shaped part to shrink into the button 1 31, the button 1 31 can move downward, and at the same time, the disc-shaped part of the elastic slider 34 can move downward in the vertical groove 121, thereby avoiding the situation that the button 1 31 moves downward while the button 2 32 is pressed.

[0042] like Figure 5 As shown, the outlet of the atomizing nozzle body 342 and the outlet of the cavity 341 are both in a trumpet shape that is expanded outwards;

[0043] The two ends of the hard tube 2 343 and the atomizing nozzle body 342 close to each other are both provided with a two-way valve flap 5;

[0044] By adopting the above solution, by setting the outlet of the atomizing nozzle body 342 and the outlet of the cavity 341 into a trumpet shape, a small amount of liquid medicine can be stored, thereby preventing the residual liquid medicine from dripping along the elastic slider 34;

[0045] At the same time, due to the two-way valve flap 5 provided on the atomizing nozzle body 342 and the second hard tube 343, it is prevented that the liquid medicine in the cavity 341 will flow out through the atomizing nozzle body 342 when the device is not in use.

[0046] like Figure 4 and Figure 6-Figure 8 As shown, a slot 261 is provided on the elastic valve core 26, and an elastic block 262 is elastically connected to the middle of the hard tube 1 25. One end of the elastic block 262 can be inserted into the slot 261 under its own elastic force, and the other end of the elastic block 262 extends to the outside of the hard tube 1 25 and is fixedly connected to a cross bar 263. A flexible hollow sphere 211 is placed inside the cylinder 21 and is located below the hard tube 1 25.

[0047] The bottom of the upper shell 12 is also fixedly connected to a guide assembly 4 for the elastic card block 262 to be separated from the card slot 261 when the button 1 31 moves downward;

[0048] The guide assembly 4 includes a guide plate 1 41 fixedly connected to the bottom of the upper shell 12, a guide plate 2 42 is fixedly connected to the top of the guide plate 1 41, a support rib 43 for supporting the guide plate 2 42 is also fixedly connected to the guide plate 1 41, an inverted T-shaped groove 44 is opened in the middle of the guide plate 1 41, the width of the upper part of the inverted T-shaped groove 44 is less than the length of the cross bar 263, and the width of the bottom of the inverted T-shaped groove 44 is greater than the length of the cross bar 263;

[0049] The connection between the second guide plate 42 and the first guide plate 41 is elastic, and the second guide plate 42 is in an inclined state in the initial state;

[0050] By adopting the above scheme, when the hard tube 1 25 and the piston 27 go down, the flexible hollow sphere 211 will be compressed first, and the elastic block 262 will be driven down at the same time, so that the cross bar 263 moves along the guide plate 2 42 until it abuts against the guide plate 1 41. At this time, the cross bar 263 cannot cross the upper part of the inverted T-shaped groove 44. At the same time, the elastic block 262 moves along the upper part of the inverted T-shaped groove 44 when it goes down. When the elastic block 262 is separated from the groove 261, the cross bar 263 moves to the bottom of the inverted T-shaped groove 44 and moves to the bottom of the inverted T-shaped groove 44 and moves to the bottom of the inverted T-shaped groove 44 when the elastic block 262 is automatically Under the action of its elastic force, one end will be reset and stuck in the slot 261, and the cross bar 263 will go over the bottom of the inverted T-slot 44. When the hard tube 25 goes up again, the cross bar 263 will squeeze the guide plate 242 and rotate it. When the cross bar 263 moves above the guide plate 242, the guide plate 242 will be reset by the elastic force at the connection with the guide plate 1 41, thereby avoiding the situation that when the hard tube 243 is separated from the cavity 341, the increase of space causes the negative pressure to drive the elastic valve core 26 to release the seal of the hard tube 25.

[0051] The working principle and use process of the present invention:

[0052] The lower cover 11 is mounted on the tank body, the button 2 32 is pressed and the elastic slider 34 is forced to move toward the hard tube 2 343 through the straight groove 33, so that the hard tube 2 343 enters the cavity 341. When the elastic slider 34 is completely contracted to the inside of the button 1 31 except for the disc-shaped part, the elastic telescopic rod 36 is compressed when the button 1 31 moves downward, and the pressure component 2 pumps liquid medicine into the hard tube 2 343 at the same time. When the button 2 32 is released, the button 1 31 is reset by the elastic force of the elastic telescopic rod 36, and then the elastic slider 34 is reset by its own elastic force. At this time, the space formed by the hard tube 2 343 and the cavity 341 increases, and the insides of the two are in a negative pressure state, so that the liquid medicine remaining at the outlet of the atomizing nozzle body 342 will be sucked back into the inner cavity of the elastic slider 34 by the negative pressure inside the cavity 341 for storage;

[0053] When the button 131 is pressed, the hard tube 125 and the piston 27 will move downward. At this time, the liquid medicine inside the cylinder 21 will enter the hard tube 125, and push the elastic valve core 26 upward to release the seal of the hard tube 125 and then enter the hard tube 2343. When the button 131 is reset, the hard tube 125 and the piston 27 move upward. At this time, the hard tube 125 is sealed by the elastic valve core 26, so that the inside of the cylinder 21 is in a negative pressure state. At this time, the elastic valve core 123 will release the seal of the pipeline 122, and the liquid medicine inside the tank will enter the cylinder 21 through the pipeline 24 and the elastic valve core 123 for storage;

[0054] When the hard tube 1 25 and the piston 27 move downward, the flexible hollow sphere 211 will be compressed first, and the elastic block 262 will be driven downward, so that the cross bar 263 moves along the guide plate 2 42 to abut against the guide plate 1 41. At this time, the cross bar 263 cannot cross the upper part of the inverted T-shaped groove 44. At the same time, the elastic block 262 moves along the upper part of the inverted T-shaped groove 44 when it moves downward. When the elastic block 262 is separated from the groove 261, the cross bar 263 moves to the bottom of the inverted T-shaped groove 44 and moves under the elastic force of the elastic block 262 itself. One end of the cross bar 263 will be reset and stuck in the slot 261, and the cross bar 263 will pass over the bottom of the inverted T-slot 44. When the hard tube 25 goes up again, the cross bar 263 will squeeze the guide plate 242 and rotate it. When the cross bar 263 moves above the guide plate 242, the guide plate 242 will be reset by the elastic force at the connection with the guide plate 1 41, thereby avoiding the situation that when the hard tube 243 is separated from the cavity 341, the increase of space causes the negative pressure to drive the elastic valve core 26 to release the seal on the hard tube 25.

The anti-pollution drug atomizing spray device according to claim 7, characterized in that: The guide assembly (4) comprises a guide plate 1 (41) fixedly connected to the bottom of the upper shell (12); a guide plate 2 (42) is fixedly connected to the top of the guide plate 1 (41); a support rib (43) for supporting the guide plate 2 (42) is also fixedly connected to the guide plate 1 (41); an inverted T-shaped groove (44) is provided in the middle of the guide plate 1 (41); the width of the upper portion of the inverted T-shaped groove (44) is smaller than the length of the cross bar (263); and the width of the bottom portion of the inverted T-shaped groove (44) is larger than the length of the cross bar (263); The connection between the guide plate 2 (42) and the guide plate 1 (41) is elastic, and in the initial state, the guide plate 2 (42) is in an inclined state.

9. A method for using an anti-pollution drug atomizing spray device, using the anti-pollution drug atomizing spray device as claimed in claim 1, characterized in that: The steps to use are as follows: S1. Install the lower cover (11) on the tank body, press button 2 (32) and force the elastic slider (34) to move toward hard tube 2 (343) through the straight groove (33), so that hard tube 2 (343) enters the cavity (341); when the elastic slider (34) is completely retracted into button 1 (31) except for the disc-shaped portion, the elastic telescopic rod (36) is compressed when button 1 (31) moves downward, and at the same time, the pressure component (2) pumps liquid medicine into hard tube 2 (343); S2. When the button 2 (32) is released, the button 1 (31) is reset by the elastic force of the elastic telescopic rod (36), and then the elastic slider (34) is reset by its own elastic force. At this time, the space formed by the hard tube 2 (343) and the cavity (341) increases, and the insides of both are in a negative pressure state, so that the liquid medicine remaining at the outlet of the atomizing nozzle body (342) is sucked back by the negative pressure inside the cavity (341) into the inner cavity of the elastic slider (34) for storage.
