[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0026] A pressing - type one - way valve pharmaceutical spraying pump for the biopharmaceutical industry, comprising a threaded cap 2 threadedly connected to the top end of a bottle body 1. A pump body 3 is snap - fitted inside the threaded cap 2. A liquid outlet pipe 4 is fixedly connected to the top end of the pump body 3. A spray head 5 is snap - fitted to the top end of the liquid outlet pipe 4. A nozzle 6 is snap - fitted inside the spray head 5. A dredging mechanism 7 is fixedly installed at one end of the nozzle 6 located inside the spray head 5. A sealing cover 8 is rotatably connected to a position on the outside of the spray head 5 corresponding to the nozzle 6.

[0027] First, a pump cover 201 is sleeved on the outside of the threaded cap 2. A tight convex ring 202 is fixedly connected to the bottom end of the inner side of the pump cover 201. When the spray head 5 is not in use, the pump cover 201 is sleeved on for protection. After the pump cover 201 is sleeved on, the tight convex ring 202 closely adheres to the outside of the spray head 5 to improve the fixing effect.

[0028] Furthermore, the threaded cap 2 and the bottle body 1 are threadedly connected through a threaded groove 203. A positioning boss 204 is fixedly connected to the outside of the bottle body 1 and at the bottom end inside the threaded cap 2. A sealing gasket 205 is installed between the threaded cap 2 and the bottle body 1. The threaded cap 2 is threadedly installed on the top end of the bottle body 1 through the threaded groove 203. It is opened to add liquid medicine to the inside of the bottle body 1. When the threaded cap 2 is screwed onto the top end of the bottle body 1, it stops at the positioning boss 204. After the threaded cap 2 is tightened, the sealing gasket 205 ensures the sealing effect between the threaded cap 2 and the bottle body 1.

[0029] Then, a pressing groove 206 is opened on the inner side of the top end of the threaded cap 2. The bottom end of the spray head 5 is slidably connected to the pressing groove 206. When pressing the spray head 5 to spray the liquid medicine, the spray head 5 is pressed into the pressing groove 206, and the stroke of the spray head 5 is fixed through the pressing groove 206 to avoid damage caused by excessive pressing force.

[0030] Even further, a liquid suction pipe 301 is inserted into the bottom end of the pump body 3. An inlet liquid groove 302 is opened at the bottom end of the liquid suction pipe 301. A filter net head 303 is sleeved on the outside of the bottom end of the liquid suction pipe 301. The liquid medicine inside the bottle body 1 is drawn out through the liquid suction pipe 301. The liquid medicine enters the inside of the liquid suction pipe 301 through the inlet liquid groove 302. When the liquid suction pipe 301 abuts against the bottom end inside the bottle body 1, the inlet liquid groove 302 at the bottom end of the liquid suction pipe 301 enables all the liquid medicine inside the bottle body 1 to be completely drawn out. At the same time, when drawing the liquid medicine, the liquid medicine is filtered through the filter net head 303 to avoid solid drug impurities in the liquid medicine from clogging the inside of the pump body 3.

[0031] Among them, the outer side of the nozzle 6 is snap-connected to the spray head 5 through a snap ring 601. One end of the nozzle 6 located inside the spray head 5 is provided with a liquid guide channel 602, and one end of the nozzle 6 located outside the spray head 5 is provided with an expansion groove 603. The nozzle 6 is installed inside the spray head 5 through the snap ring 601. When the liquid medicine is sprayed, it is sprayed through the liquid guide channel 602, and then the spraying range is diffused through the expansion groove 603, so that the atomized liquid medicine can be evenly coated on the required surface of the human skin.

[0032] Secondly, the dredging mechanism 7 includes a bullet head 701 rotatably connected to one end of the nozzle 6 located inside the spray head 5. The bullet head 701 is rotatably connected to the nozzle 6 through a connecting shaft 702. A plurality of groups of blades 703 are fixedly connected to the outer side of the bullet head 701. A dredging rod 704 is fixedly connected to one side of each group of blades 703 close to the nozzle 6. When the liquid medicine is sprayed from the nozzle 6, when the liquid medicine passes through the plurality of groups of blades 703 and is connected by the connecting shaft 702, it can drive the bullet head 701 to rotate, so that the plurality of groups of dredging rods 704 rotate accordingly to prevent the inside of the nozzle 6 from being blocked after long-term use, thereby ensuring the continuous output of the medicine and avoiding affecting the treatment effect.

[0033] Finally, the bottom end of the sealing cover 8 is rotatably connected to the spray head 5 through a rotating shaft 801. A torsion spring 802 is sleeved on the outer side of the rotating shaft 801. A sealing inner pad 803 is fixedly connected to the position corresponding to the nozzle 6 on the inner side of the sealing cover 8. When the spray head 5 is not in use, the sealing cover 8 is in a closed state, and the outer side of the nozzle 6 is sealed by the sealing inner pad 803 to prevent the residual liquid medicine from flowing out and being wasted, and at the same time to avoid the difficulty of cleaning the flowing-out liquid medicine. A pressing block 804 is slidably connected to the inside of the top end of the spray head 5. A spring 805 is fixedly connected to one end of the pressing block 804 located inside the spray head 5. A fixing block 806 is fixedly connected to the bottom end of the pressing block 804. A fixing hole is provided at the position corresponding to the fixing block 806 on the top end of the sealing cover 8. When pressing the spray head 5 to spray the liquid medicine, press the pressing block 804 to move it downward, so that the fixing block 806 disengages from the inside of the fixing hole to release the fixation of the sealing cover 8, and the sealing cover 8 is automatically opened under the action of the torsion spring 802, so that the liquid medicine can be sprayed and used, and at the same time, the residual liquid medicine inside the nozzle 6 can be sprayed out together after the liquid medicine is sprayed, thereby avoiding the waste of the liquid medicine.

[0034] In this embodiment, the implementation scenario is specifically as follows: The threaded cap 2 is threadedly installed at the top of the bottle body 1 through the threaded groove 203. After it is opened, the inside of the bottle body 1 is filled with liquid medicine. When the nozzle 5 is not in use, the sealing cap 8 is in a closed state, and the outer side of the nozzle 6 is sealed by the sealing inner pad 803 to prevent the residual liquid medicine from flowing out and being wasted, and at the same time to avoid the difficulty of cleaning the flowing out liquid medicine. When pressing the nozzle 5 to spray the liquid medicine, pressing the nozzle 5 causes the pump body 3 to draw the liquid medicine out of the bottle body 1. When pressing the nozzle 5 to spray the liquid medicine, pressing the pressing block 804 to move it downward, so that the fixing block 806 disengages from the inside of the fixing hole to release the fixation of the sealing cap 8, and the sealing cap 8 is automatically opened under the action of the torsion spring 802, so that the liquid medicine can be sprayed for use. At the same time, after the liquid medicine is sprayed, the residual liquid medicine inside the nozzle 6 can be sprayed out together, thus avoiding the waste of the liquid medicine. When the liquid medicine is sprayed out from the nozzle 6, when the liquid medicine passes through multiple groups of blades 703, it can drive the bullet head 701 to rotate under the connection of the connecting shaft 702, so that multiple groups of dredging rods 704 rotate to avoid the blockage inside the nozzle 6 after long-term use. The whole operation process is simple and convenient. Compared with the existing pressing type biopharmaceutical one-way valve dosing spray pump, the present utility model can avoid the blockage of the liquid medicine through the design, ensure the continuous output of the medicine, avoid affecting the treatment effect, and at the same time can avoid the waste of the liquid medicine.

[0035] Although the embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
