Description
Technical Field
The invention relates to a medical appliance product, in particular to an air pressure adjusting mechanism of an extrusion cleaning device and a cleaning bottle.
Background
At present, products for cleaning the nasal cavity and the nasal sinuses have various design ideas, one of which is based on extruding the bottle body to compress the inner cavity space of the bottle body, thereby improving the pressure intensity and extruding and spraying the liquid medicine. In order to ensure the realization of the technical scheme, the existing product is often designed with a movable valve capable of floating up and down, when the movable valve is extruded, the movable valve floats upwards, and the vent on the surface of the shell can be blocked and closed, so that the liquid medicine is extruded only from the liquid outlet; when the extrusion is stopped, the bottle body is reset, and air enters the shell to balance the internal and external air pressure.
However, the existing products mainly have two problems at present, and the service efficiency of the existing products is seriously affected. Firstly, the existing movable valve is shaped like a reverse-buckled bowl, when the movable valve floats upwards, the movable valve can incline at an angle and cannot well block the vent of the shell, so that part of air overflows from the vent when the bottle body is extruded, and the liquid outlet quantity of the liquid outlet is reduced; second, the current design cannot realize rapid balance of internal and external air pressure when the bottle is reset, so that a patient needs to wait for a long time to squeeze the bottle for the second time after squeezing the bottle once. In addition, the existing product still has slight liquid medicine overflow phenomenon at the liquid outlet of the shell.

More preferably, the bottom surface of the reflux groove is provided with a gun head which extends upwards and is provided with an opening at the tail end, and the opening position of the gun head corresponds to the center of the bottom surface of the movable flap.
According to the invention, the bottle body is gradually widened from top to bottom, and the outer edge of the bottom surface of the bottle body is formed with a chamfer angle of 40-60 degrees in an inclined manner. Preferably, the surface of the bottle body is provided with a texture which plays a role in skid resistance.
The beneficial effects are that: the product of the invention is substantially improved aiming at the defect of slower internal and external air pressure balance speed of the existing product, thereby not only improving the backlog liquid outlet efficiency of the product, but also increasing the dustproof and pollution-proof functions of the product, and further improving the liquid medicine overflow problem of the original product. The air pressure adjusting mechanism and the cleaning bottle thereof enable the functions of the extrusion cleaning device to be more perfect, and the use experience of patients is improved.
