Highly it is less than second feature.
With reference to the accompanying drawing of specification, it is further described by specific embodiment of the invention, sends out this
Bright technical scheme and its advantage is clearer, clear and definite.It is exemplary, purport below with reference to Description of Drawings embodiment
It is of the invention explaining, and be not considered as limiting the invention.
Shown by reference picture 1-5, it is that the present invention preferably provides the humidifier that added water in one kind, and it includes：Support 1,
The bottom that water tank 2 and inlet valve mechanism 3, wherein water tank 2 are arranged at the water tank 2 on support 1 is provided with inlet valve mechanism 3.
The inlet valve mechanism 3 includes extending to the lower water push rod 31 in water tank, the sealing on lower water push rod 31
32nd, wheel body 33, the stepper motor 34 and connection stepper motor 34 that drive rotation wheel body 33 to make the lower up and down action of water push rod 31 are rotated
Controller（Not shown in figure）, the connection collector nozzle of water tank 2 lower water cover 35, in lower water cover chamber being flexibly supported on lower water
The spring 36 of push rod 31, located at the push rod 37 rotated between wheel body 33 and lower water push rod 31 and the elastomer for being connected to push rod 37
38, the rotation wheel body 33 is cam.The built-in atomized air flow path 21 of the water tank 2, water tank upper is provided with the opening portion 22 that adds water,
The opening portion 22 that adds water removably is assembled with lid 23.The top of atomized air flow path 21 is provided with fog outlet 24 and lid sets fog outlet
Go out mist lid 25.Controller connects power panel 5, and the controller is single-chip microcomputer.
Controller connection water level detecting portion 4, the water level detecting portion includes floating magnet ring 41 and magnetic reed switch 42.Magnetic red is opened
Closing 42 includes the first magnetic Huang switch 421 and the second magnetic reed switch 422 that parallel interval is set.The yellow switch 421 and second of first magnetic
The switch of magnetic red 422 is in different height, when control water is operated, when the ring of floating magnetic 41 reaches the high position 422a of the second magnetic reed switch 422,
Controller drives rotation wheel body 33 to allow the lower downward actuation of water push rod 31 sealing is closed collector nozzle 39 and realizes that stopping adds water；It is described
Floating magnet ring is to 41 up to power-off or delay cut-off during 421 low level 422a of the first magnetic reed switch realizing automatically powering off protection.The
The yellow switch 421 of one magnetic is additionally provided with the position 421b and closure energization area 421C of upper end disconnection.Magnetic reed switch is using one on the other
Mode puts together side by side, is whole machine water shortage shape when floating magnet ring 41 is in the lower end of the first magnetic reed switch 422 disconnects position
State；Close energization area 421C when floating magnet ring 41 is in the first magnetic red, it is not high enough to be considered as water level, floating magnet ring 41 continue on move
During to the high position 422a of the second magnetic reed switch 422, being considered as water level has expired, and is not required to add water.When anhydrous in because of water tank, floating magnet ring
After 41 times for disconnecting that position or time reach program setting in the first magnetic reed switch lower end, it is considered as the real water shortage of water tank, now
Whole product will be automatically powered off.
It is incorporated into above-mentioned and combines all accompanying drawings in the lump, further illustrates operation principle of the invention：When being powered anhydrous,
Floating magnet ring avales, and the first magnetic reed switch disconnects, and after controller receives power-off signal, sending instruction makes positive turn of synchronous motor
It is dynamic, drive drive to rotate to an angle, make to be moved into water on its push rod in rotary course, energy again while elastomer plays sealing
Deformation is produced to produce screen resilience, lower water push rod to be risen by push rod and drive sealing to depart from sealing position in push rod moving process
Put, aqueous are flowed downwardly into, to realize water inlet.
After liquid level gradually rises, floating magnet ring floats, when liquid level reach the second magnetic reed switch it is high-order when, controller receive
To after power on signal, sending instruction rotates backward synchronous motor work, drives drive to reversely rotate certain angle, drive
Its push rod is set to be moved down in the kind that resetted in elastomer in rotary course, lower water push rod falls under the action of the spring, and drives close
Envelope subordinate is moved to be formed with water tank bottom and seals, and aqueous cannot be flowed down；To realize water shutoff.
In work when occurring descending water, attaching plug is pulled up in power-off suddenly or consumption, to avoid aqueous from flowing down always,
The power panel for now being connected by setting controller is powered, and synchronous motor is worked, and is increased to liquid level and is enough to make the second magnetic red
It is stopped after being disconnected when switch is high-order.
When using, when needing to add water, lid is opened, can be directly from the opening portion 22 that adds water toward adding water in water tank.
Sum it up, simple structure of the invention, effectively compact, quick for installation, safe and reliable, long service life, reduction
Manufacturing cost；And it can automatically carry out lower water, water shutoff effect；While reduces cost, can reliably control to add water and break again
Water, reach add water it is convenient and swift, it is with low cost, use reliability.Therefore, it is a kind of economy and technical has superior function
Product.
Although describing the present invention according to preferred embodiment, there is change, the displacement being within the scope of the present invention
And equivalence.It shall also be noted that there are many substitute modes to realize the present invention.
Accordingly, it is intended to appended claims are construed to include falling all in true spirit and scope of the present invention
Such change, displacement and equivalence.From the foregoing description of structures and principles person of ordinary skill in the field should
Work as understanding, the present invention is not limited to above-mentioned specific embodiment, on the basis of the present invention changing using techniques well known
Enter and replacement all falls within protection scope of the present invention, it should be limited by each claim.
