A nasal anti-allergy nebulizer

Abstract

The present invention relates to a nasal anti-allergy nebulizer, comprising: a bottle body, a negative pressure mechanism, a connecting cylinder, a pressing cover, a nozzle, a protective cover and a piston. In the present invention, the negative pressure mechanism is adaptively inserted into the mouth section of the bottle, and the piston is adaptively and slidably installed at the inner bottom of the bottle body. After pressing the pressing cover and the negative pressure mechanism, the negative pressure mechanism evacuates the negative pressure from the solid gel in the bottle body. Under the action of the negative pressure, the solid gel is thixotropic to a liquid state. At the same time, the piston moves upward under the action of the external atmospheric pressure and pushes the solid gel in the bottle body upward. Subsequently, the liquid gel passes through the mouth section and is sprayed out in an atomized form from the outlet of the nozzle. The liquid gel sprayed into the nose will instantly turn into a solid state when it loses pressure, so as to adhere more firmly to the nasal cavity and part of the nasal concha. The nebulizer is simple to operate, has strong spraying power, and can change the state of the gel to enhance the spraying effect.

Description

Technical Field

[0001] The present invention relates to the technical field of sprayers, and particularly relates to a nasal anti-allergy sprayer. Background Art

[0002] In the daily living environment of people, there are various allergy-causing substances, which are medically called "allergens". Allergic rhinitis, also known as allergic rhinitis, is a chronic inflammatory reaction disease of the nasal mucosa caused by some individuals coming into contact with allergens, characterized mainly by nasal itching, sneezing, a large amount of watery nasal discharge, and nasal mucosal swelling pain.

[0003] As an anti-allergy specific drug, the main administration methods of gel are smear type and spray type. Among them, the smear type needs to be applied with the help of a cotton swab, which not only wastes part of the gel but also can only be applied to the nasal vestibule, and the medicinal effect is limited; while the spray type can cover the nasal cavity and part of the nasal concha.

[0004] However, existing spray gels generally have problems such as insufficient jet power and partial backflow of the jet liquid, resulting in gel contamination.

[0005] Therefore, how to design a nasal anti-allergy sprayer with strong jet power and capable of preventing the backflow of the jet liquid is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0006] The present invention provides a nasal anti-allergy sprayer to solve the technical problems of insufficient jet power and backflow of the jet liquid in existing sprayers.

[0007] The technical solution of the present invention to solve the above technical problems is as follows. A nasal anti-allergy sprayer includes: a bottle body, a negative pressure mechanism, a connecting cylinder, a pressing cover, a nozzle, a protective cover, and a piston.

[0008] The bottle body includes a bottle mouth section and a bottle body connected integrally; the negative pressure mechanism is adaptively inserted into the bottle mouth section and one end thereof extends out of the bottle mouth section, and the inlet of the inserted end of the negative pressure mechanism communicates with the inner cavity of the bottle body; the connecting cylinder is detachably connected to the outer peripheral side of the bottle mouth section corresponding to the outer peripheral side of the negative pressure mechanism; the pressing cover is slidably connected to the inner wall of the connecting cylinder along the axial direction of the connecting cylinder and can press the negative pressure mechanism.

[0009] The nozzle is fixed on the pressing cover and its inlet passes through the outer wall of the pressing cover and communicates with the outlet of the extending end of the negative pressure mechanism; the protective cover is detachably connected to the end of the connecting cylinder far from the bottle mouth section corresponding to the outer peripheral side of the nozzle; the piston is adaptively slidably connected to the bottom of the inner cavity of the bottle body.

[0010] The beneficial effects of the present invention are as follows: By fitting and inserting the negative pressure mechanism into the bottle mouth section, and slidingly installing a piston on the inner bottom of the bottle body, after pressing the pressing cap and the negative pressure mechanism, the negative pressure mechanism evacuates the negative pressure from the solid gel inside the bottle body. Under the action of the negative pressure, the solid gel is thixotroped into a liquid state. At the same time, the piston moves upward under the action of the external atmospheric pressure, and pushes the solid gel inside the bottle body upward. Subsequently, the liquid gel passes through the bottle mouth section and is sprayed out in an atomized state from the outlet of the nozzle. The liquid gel sprayed into the nose loses pressure and will instantly turn back into a solid state, so as to adhere more firmly to the nasal cavity and part of the nasal concha. The sprayer is simple to operate, has strong spraying power, and can change the state of the gel to enhance the spraying effect.

[0011] On the basis of the above technical solution, the present invention can be further improved as follows.

[0012] Further, an annular groove is axially formed on the end face of the connecting cylinder away from the bottle body; the pressing cap includes an annular cylinder, a hemispherical cap and a pressing column. The annular cylinder is slidably connected in the annular groove; the edge of the open end of the hemispherical cap is fixedly aligned with the edge of the open end of the annular cylinder extending out of the annular groove; one end of the pressing column is fixed to the bottom of the hemispherical cap and the other end abuts against the extending end of the negative pressure mechanism. A through hole is axially formed inside the pressing column and penetrates through the other end thereof. The through hole is communicated with the outlet of the extending end of the negative pressure mechanism; the nozzle is fixed on the outer side wall of the hemispherical cap and its inlet is fixed and communicated with the through hole.

[0013] The beneficial effect of adopting the above is: By fixing the nozzle on the side top of the hemispherical cap, it is convenient for the nozzle and the hemispherical cap to be inserted into the nose conformally, shortening the spraying distance and improving the spraying effect.

[0014] Further, a plugging groove is formed on the end face of the other end of the pressing column corresponding to the outer periphery of its through hole; the extending end of the negative pressure mechanism is detachably plugged into the plugging groove.

[0015] The beneficial effect of adopting the above is: The extending end of the negative pressure mechanism is detachably plugged into the plugging groove. On the one hand, it can improve the connection stability between the pressing cap and the negative pressure mechanism, and on the other hand, it can improve the stability of blind plugging.

[0016] Further, the negative pressure mechanism includes a liquid pumping cylinder, a one-way valve, a connecting ring, a first movable cylinder, a spring, a second movable cylinder, a piston ring and a liquid outlet pipe.

[0017] The liquid pumping cylinder is coaxially and fittingly inserted into the bottle mouth section and one end thereof extends out of the bottle mouth section. The inlet of the inserted end of the liquid pumping cylinder is communicated with the inner cavity of the bottle body; the one-way valve is fixed at the outlet of the inserted end of the liquid pumping cylinder; the outer wall of the connecting ring is hermetically fixed on the inner wall of the extending end of the liquid pumping cylinder.

[0018] The outer wall of the first movable cylinder is slidably connected to the inner wall of the connecting ring, and one end of the first movable cylinder is inserted into the liquid pumping cylinder; the spring is sleeved on the outer peripheral side of the first movable cylinder, one end of the spring is fixed to the top end of the movable cylinder, and the other end of the spring is fixed to the connecting ring; the second movable cylinder is fixedly penetrated in the first movable cylinder, and one end of the second movable cylinder passes through the first movable cylinder and extends into the liquid pumping cylinder; the piston ring is slidably connected to the inside of the liquid pumping cylinder along the axial direction of the liquid pumping cylinder and is sleeved and fixed on the outer wall of the first movable cylinder near the end where the first movable cylinder extends into the liquid pumping cylinder, and one end face of the piston ring abuts against the bottom end of the first movable cylinder; one end of the liquid outlet pipe is fixed and communicated with the outlet at the extending end of the first movable cylinder, the other end of the liquid outlet pipe is detachably inserted into the insertion groove, and the outlet at the other end of the liquid outlet pipe is communicated with the through hole of the pressing column.

[0019] Instructions for using the negative pressure mechanism: Press the hemispherical cover downward, the pressing column simultaneously presses the liquid outlet pipe downward, and the liquid outlet pipe presses the first movable cylinder to slide downward along the axial direction of the connecting ring. The first movable cylinder then drives the second movable cylinder and the piston ring to slide downward along the axial direction of the liquid pumping cylinder. During the downward sliding process of the second movable cylinder and the piston ring, the air in the liquid pumping cylinder will be gradually discharged. At this time, release the hemispherical cover, the spring returns to its initial state, and drives the first movable cylinder, the second movable cylinder and the piston ring to move upward. The space in the liquid pumping cylinder instantaneously increases to generate a vacuum negative pressure. At this time, the piston moves upward under the action of the external atmospheric pressure, pushing the solid gel in the bottle body to be ejected from the outlet of the nozzle. Among them, the solid gel entering the liquid pumping cylinder will instantaneously change into a liquid state under the action of the negative pressure and be ejected from the outlet of the nozzle in an atomized state.

[0020] The further beneficial effect of adopting the above is: The spring reset drives the first movable cylinder, the second movable cylinder and the piston ring to move upward, which will instantaneously expand the internal cavity volume of the liquid pumping barrel, generate a short-term vacuum negative pressure. Under the action of the external atmospheric pressure, it will push the piston upward, and the piston pushes the solid gel to be ejected from the outlet of the nozzle in an atomized state through the liquid pumping barrel.

[0021] Further, the liquid pumping cylinder, the one-way valve, the connecting ring, the first movable cylinder, the spring, the second movable cylinder, the piston ring and the liquid outlet pipe are all made of transparent plastic material.

[0022] The further beneficial effect of adopting the above is: It is convenient to observe whether there is unsprayed gel in the negative pressure mechanism.

[0023] Further, it further includes a first fixing ring, and the first fixing ring is sleeved and fixed on the outer wall of the extending end of the liquid pumping cylinder, and one end face of the first fixing ring can be lapped on the edge of the bottle mouth section.

[0024] The further beneficial effects of the above are as follows: The first fixing ring is sleeved on the outer wall of the protruding end of the liquid pumping cylinder. On the one hand, it can improve the fixing stability of the liquid pumping cylinder, and on the other hand, it can improve the sealing performance between the liquid pumping cylinder and the bottle mouth section.

[0025] Furthermore, the negative pressure mechanism further includes a sealing ring, and the sealing ring is sleeved on the outer wall of the liquid pumping cylinder near the protruding end corresponding to the space between the first fixing ring and the bottle mouth section.

[0026] The further beneficial effects of the above are as follows: The sealing ring is fixed on the outer wall of the liquid pumping cylinder between the first fixing ring and the bottle mouth section, which can further strengthen the sealing performance between the liquid pumping cylinder and the bottle mouth section.

[0027] Furthermore, it further includes a third fixing ring, and the third fixing ring is sleeved on the outer wall of the connecting ring and one end face thereof can overlap on the edge of the outlet of the protruding end of the liquid pumping cylinder.

[0028] The further beneficial effects of the above are as follows: The third fixing ring can facilitate the installation of the connecting ring.

[0029] Furthermore, it further includes a second fixing ring, and the second fixing ring is sleeved on the outer wall of the protruding end of the first movable cylinder; one end of the spring abuts against the second fixing ring, and the other end abuts against the third fixing ring.

[0030] The further beneficial effects of the above are as follows: The spring is sleeved on the outer peripheral side of the first movable cylinder and one end thereof abuts against the second fixing ring, and the other end abuts against the third fixing ring, which can prevent the first movable cylinder from being completely inserted into the connecting ring.
