Abstract
A kind of filter device of noresidue liquid-drop machine provided by the invention, including bottle body and filter assemblies；Filter assemblies are located at one end of bottle body, connect with sealing bottle；Filter assemblies include water dropper, filter and infusion channel；Water dropper is located at one end of bottle body, and filter is located at the periphery of infusion channel, and infusion channel runs through water dropper.A kind of filter device of noresidue liquid-drop machine provided by the invention, the function of blocking and open is formed using the movable check valve moveing freely in filtering body, when bottle body is upright, movable check valve is moved down because of gravity, it is covered on the curved section of valve pool, air enters bottle body by grade one filter and secondary filter, it ensure that the germ-free condition of air, when bottle body is inverted, when oppressing bottle body progress dropping liquid, movable check valve falls in the straightway of valve pool, since compressing bottle body causes air pressure in bottle body to increase, so that movable check valve is pressed in filtering body, air is prevented to enter bottle body, guarantee pressure in bottle, complete dropping liquid.
Description
Technical field
The present invention relates to a kind of filter devices of noresidue liquid-drop machine.
Background technique
Liquid-drop machine is widely used as present daily life product because can accurate dropping liquid, answered extensively
The medical applications such as eye drops are used, but current liquid-drop machine is in use, medical fluid can remain after dripping in liquid droping port
Medical fluid, normal medical fluid can all require isolation air to prevent from polluting in sealing, once remain in the medical fluid of liquid droping port makes again
Used time is bound to touch other medical fluids in medicine bottle, is contaminated so as to cause whole bottle medicine, influence using.
Traditional liquid-drop machine is to carry out dropping liquid using the channel on water dropper, it is therefore desirable to be increased on medical fluid transmission pipeline single
To valve, prevent thering is extraneous gas to enter bottle body when oppressing bottle body, the pressure that liquidates and medical fluid can not be exported, and in order to enable medical fluid
Noresidue needs that guide post is arranged in drip, cannot so use traditional check valve, cannot achieve pressure control and filtering
Management.
Summary of the invention
Technical problem to be solved by the present invention lies in: a kind of filter device of noresidue liquid-drop machine is provided, on liquid-drop machine
When diversion column is set, check valve can be continued to use, guarantees the normal use of bottle body.
In order to solve the above technical problems, the technical scheme is that a kind of filter device of noresidue liquid-drop machine, including
Bottle body and filter assemblies；The filter assemblies are located at one end of the bottle body, connect with the sealing bottle；
The filter assemblies include water dropper, filter and infusion channel；The water dropper is located at the one of the bottle body
End, is fixedly connected with the bottle body；The filter is located at the periphery of the infusion channel, fixes with the water dropper
It connects, bottle body inner space described in connection；The infusion channel runs through the water dropper, is connected with the bottle body；
Movable check valve is provided in the filter, the movable check valve is located in the filter, with
The inner wall of the filter is in contact, free to slide along the vertical direction in the filter.
Further, movable check valve shape in a ring.
Further, the filter further includes filtering body, grade one filter and secondary filter；The filtering body
Positioned at the upside of the filter, it is fixedly connected with the water dropper；The grade one filter is located at the filtering body
Inside, in the outer circle of the infusion channel；The secondary filter is located at the lower section of the grade one filter,
It is connected with the grade one filter.
Further, the filtering body is provided with valve pool, and the valve pool is located at the inside of the filtering body, with institute
The movable check valve stated is corresponding.
Further, the valve pool is provided with straightway and curved section, and the straightway is located at the filtering body
Upside, matched with the movable check valve；The curved section is located at the lower section of the straightway, and described straight
Line segment is connected, and prevents the movable check valve mobile.
Further, the curved section is in the shape of big at both ends and small in middle.
Compared with prior art, the filter device of a kind of noresidue liquid-drop machine provided by the invention, using in filtering body
The movable check valve that move freely forms the function of blocking and open, and when bottle body is upright, movable check valve is because gravity is to moving down
It is dynamic, it is covered on the curved section of valve pool, air enters bottle body from filtering body, compresses inside check valve sealed bottle body, and air is logical
It crosses grade one filter and secondary filter enters bottle body, ensure that the germ-free condition of air, when bottle body is inverted, compressing bottle body is carried out
When dropping liquid, movable check valve falls in the straightway of valve pool, since compressing bottle body causes air pressure in bottle body to increase, so that activity is unidirectional
Valve is pressed in filtering body, and air is prevented to enter bottle body, guarantees pressure in bottle, oppresses out medical fluid, completes dropping liquid.
Detailed description of the invention
