Description

Technical Field

[0001] The utility model relates to the technical field of sprayers, in particular to a nasal sprayer capable of automatically increasing pressure. Background Art

[0002] When the nasal cavity has a disease, most of the time it needs to be treated with nasal spray. The method of nasal spray is very important. The method is: stand, spray the right nostril twice with the left hand, and spray the left nostril twice with the right hand. The direction is obliquely toward the outer wall of the nasal cavity, and you cannot spray toward the middle. Nasal spray is mostly used for the treatment of allergic rhinitis, chronic rhinitis and sinusitis. The dosage of nasal spray is small, the side effects are small, but it can reach the lesion directly, the effect is rapid, and the therapeutic effect is obvious. Generally, you cannot spray the nose for a long time to avoid side effects.

[0003] In the existing nasal sprayer, the medicine is contained in a soft bag and the inside of the spray bottle is pressurized. After a long period of use, the internal pressure drops, which will cause the amount of medicine sprayed to decrease, or residual medicine is difficult to spray out. At the same time, the size of the spray is not easy to adjust and control, and can only be controlled by adjusting the pressure of the pressing valve, which is inconvenient to use. Therefore, a nasal sprayer that can automatically increase the pressure is proposed. Utility Model Content

[0025] See also Figure 1-3 A nasal sprayer capable of automatically increasing pressure comprises a tank body 2, a push valve 1 mounted on the top of the tank body 2, and a nozzle 10 mounted on the push valve 1. A pressure chamber 5 is arranged inside the tank body 2, a soft bag 4 is installed on the pressure chamber 5, a medicine spraying pipe 16 is arranged between the top of the soft bag 4 and the push valve 1, so that the medicine inside the soft bag 4 can be squeezed out by the pressure inside the pressure chamber 5, the push valve 1 is connected with the nozzle 10, so that by pressing the push valve 1, the medicine in the soft bag 4 can be squeezed to the nozzle 10 by the pressure inside the pressure chamber 5, a pressurized chamber 6 is arranged at the bottom of the tank body 2, and a pressure chamber 6 is arranged between the pressurized chamber 6 and the pressure chamber 5. A pressure relief valve 11, wherein a partition is fixedly installed between the pressurization cabin 6 and the pressure cabin 5, and the pressure relief valve 11 is movably installed on the partition. When the pressure inside the pressurization cabin 6 reaches a certain size, the pressure relief valve 11 can be squeezed into the interior of the pressure cabin 5, thereby making the interior of the pressurization cabin 6, so that the pressurization cabin 6 and the pressure cabin 5 form a whole, thereby achieving the effect of increasing the pressure of the pressure cabin 5, so that the residual medicine in the soft bag 4 can be effectively squeezed out. A pressurization valve 12 is installed at the bottom of the tank body 2, wherein the pressurization valve 12 is a one-way valve, similar to the air filling valve at the bottom of a lighter, so that it is convenient to fill the pressurization cabin 6 with air from the outside of the tank body 2 to increase the pressure inside the pressurization cabin 6.

[0026] In this embodiment, a rubber base 7 is mounted on the bottom of the tank body 2. The rubber base 7 can effectively prevent the pressure chamber 6 from being deflated and increase the friction between the tank body 2 and the desktop, thereby facilitating the placement of the sprayer.

[0027] In this embodiment, the outside of the tank body 2 is covered with an anti-slip cover 3. When the hand is holding the sprayer to press the push valve 1, the palm is likely to slide against the tank body 2, thereby affecting the pressing effect of the push valve 1. The anti-slip cover 3 can effectively increase the friction between the palm and the tank body 2, thereby achieving an anti-slip effect.

[0028] In this embodiment, a mounting seat 8 is installed on the press valve 1, a rotating seat 9 is threadedly connected to the mounting seat 8, and a nozzle 10 is installed on the rotating seat 9, wherein a threaded sleeve 13 is installed at the bottom of the rotating seat 9, a rubber plug 15 is installed at the bottom of the threaded sleeve 13, a connecting pipe 14 is arranged between the threaded sleeve 13 and the rotating seat 9, and the nozzle 10 is connected to the spray pipe 16 through the connecting pipe 14. By means of a threaded connection, the rotating seat 9 can adjust the distance between the threaded sleeve 13 and the mounting seat 8 by rotating, thereby facilitating the adjustment of the depth of the rubber plug 15 inserted into the spray pipe 16, thereby achieving the effect of precisely adjusting the spray metering.

[0029] Working principle: When there are residual medicines in the soft bag 4, the pressurizing valve 12 is used to pressurize the inside of the pressurizing chamber 6. When the pressure inside the pressurizing chamber 6 reaches a certain level, the pressure relief valve 11 will be squeezed into the pressure chamber 5, so that the air inside the pressurizing chamber 6 will flow into the inside of the pressure chamber 5, thereby achieving the effect of pressurizing the pressure chamber 5. Then, through the increased pressure in the pressure chamber 5, the residual medicines in the soft bag 4 can be squeezed into the spray pipe 16, and then squeezed out to the nozzle 10 through the connecting pipe 14 for spraying. When it is necessary to adjust the spray size, the rotating seat 9 is rotated to adjust the depth of the rubber plug 15 inserted into the spray pipe 16, so as to achieve the effect of controlling the spray size.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
