Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a novel nasal spray head. Background Art

[0002] At present, the medical spray heads on the market, especially the one-yuan medical spray heads, have complex internal structures. When patients undergo nasal or oral spray treatment, they need to use a medicine bottle and a nozzle to spray the liquid medicine on the lesion. The liquid medicine needs to pass through a complex pressure structure to be sprayed out. In actual use, the liquid medicine cannot be quickly discharged in a push-and-go manner, and the water discharge mode cannot be changed and adjusted, which causes trouble in use. Utility Model Content

[0003] In view of the above problems, the purpose of the present utility model is to provide a novel nasal spray nozzle with rapid water delivery and adjustable water delivery mode.

[0004] To achieve the above-mentioned purpose, the utility model provides a new type of nasal spray head, including a spray head, a nozzle arranged on the spray head, and an atomizing core column connected to the nozzle arranged in the spray head, wherein the nozzle includes a straight tube connected to the spray head and threadedly connected to the atomizing core column internally, and a thin tube connected to the straight tube and having a smaller diameter than the straight tube is arranged at the end of the straight tube; the nozzle is provided with a water outlet regulating mechanism connected to the spray head.

[0005] The water outlet regulating mechanism comprises a knob cover which is covered on the nozzle and is threadedly connected with a straight pipe on the nozzle, and a water outlet which is communicated with the capillary is arranged on the top of the knob cover.

[0006] A sealing ring is arranged on the straight pipe between the knob cover and the straight pipe.

[0007] In some embodiments, a thread groove is provided on the straight tube body between the straight tube and the knob cover, and an annular protrusion that is stuck in the thread groove is provided on the inner wall of the knob cover at a position corresponding to the thread groove.

[0008] When the knob cover rotates forwardly along the thread groove, the knob cover extends upward relative to the nozzle, and at this time, the water outlet on the knob cover is separated from the opening at the end of the capillary tube.

[0009] When the knob cover rotates in the opposite direction along the thread groove, the knob cover is retracted downward relative to the nozzle, and at this time, the water outlet on the knob cover fits with the opening at the end of the capillary tube.

[0010] In some embodiments, the knob cover can be rotated 180 degrees in a forward or reverse direction relative to the nozzle.

[0011] In some embodiments, an annular recess for placing a sealing ring is provided on the straight tube.

[0012] In some embodiments, the diameter of the sealing ring is greater than the diameter of the annular recess.

[0013] The beneficial effect of the utility model is that it has the effect of fast water discharge and adjustable water discharge mode. Since a knob cover with a water outlet is added to the nozzle after improvement, the distance between the opening at the end of the capillary tube and the water outlet on the knob cover can be adjusted by rotation to switch between the two modes of atomization and direct spraying, that is, the water outlet on the knob cover fits with the opening at the end of the capillary tube, and the water outlet produces an atomization effect; the water outlet on the knob cover is separated from the opening at the end of the capillary tube, and the water outlet produces a direct spraying effect. In addition, a sealing ring is installed on the straight tube to increase the injection pressure inside the nozzle, so that the liquid medicine can be easily sprayed into the nasal cavity to reach the lesion, and the purpose of pressing and discharging the liquid medicine can be achieved. In this way, the effect of fast water discharge and adjustable water discharge mode is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-6As shown, a novel nasal spray head comprises a spray head 1, a nozzle 2 provided on the spray head 1, and an atomizing core column 3 connected to the nozzle 2 provided inside the spray head 1, the nozzle 2 comprises a straight tube 21 connected to the spray head 1 and threadedly connected to the atomizing core column 3 inside, and a thin tube 22 connected to the straight tube 21 and having a smaller diameter than the straight tube 21 is provided at the end of the straight tube 21. A water outlet regulating mechanism 4 connected to the spray head 1 is provided on the nozzle 2. The water outlet regulating mechanism 4 comprises a knob cover 41 covered on the nozzle 2 and threadedly connected to the straight tube 21 on the nozzle 2, and a water outlet 42 connected to the thin tube 22 is provided on the top of the knob cover 41. A sealing ring 5 is provided on the straight tube 21 between the knob cover 41 and the straight tube 21, which has the function of increasing the spray pressure inside the spray head 1, thereby easily spraying the liquid medicine to the nasal cavity to reach the lesion. A thread groove 23 is provided on the body of the straight tube 21 located between the straight tube 21 and the knob cover 41; an annular protrusion 24 is provided on the inner wall of the knob cover 41 corresponding to the position of the thread groove 23, which is stuck in the thread groove 23; when the knob cover 41 rotates forward along the thread groove 23, the knob cover 41 extends upward relative to the nozzle 2, and at this time, the water outlet 42 on the knob cover 41 is separated from the opening at the end of the capillary 22, which is a direct spray mode. When the knob cover 41 rotates reversely along the thread groove 23, the knob cover 41 is retracted downward relative to the nozzle 2, and at this time, the water outlet 42 on the knob cover 41 fits with the opening at the end of the capillary 22, which is an atomization mode. The angle of the knob cover 41 relative to the nozzle 2 in the forward or reverse rotation is 180 degrees. An annular recess 6 for placing a sealing ring 5 is provided on the straight tube 21. The diameter of the sealing ring 5 is larger than the diameter of the annular recess 6.

[0022] When in use, the water spraying state can be switched between the atomization mode and the direct spraying mode by rotating the knob cover 41, so as to achieve an unattainable spraying effect. The two spraying states can be obtained by rotating the knob 180 degrees to meet the needs of different users.

[0023] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
