Specific embodiment
To further illustrate each embodiment, the utility model is provided with accompanying drawing.These accompanying drawings are in the utility model is disclosed
A part for appearance, it is mainly used to illustrate embodiment, and running of the associated description of specification to explain embodiment can be coordinated former
Reason.Coordinate and refer to these contents, those of ordinary skill in the art will be understood that other possible implementation methods and this practicality are new
The advantage of type.Component in figure is not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
As depicted in figs. 1 and 2, a kind of automatic water-feeding device, including the case 10 that adds water, storage tank 20 and water-level control apparatus 30,
The case 10 that adds water is located at the top of storage tank 20, and filler 12 and delivery port 14 are respectively arranged with the top and bottom of the water tank,
Water-level control apparatus 30 are provided with delivery port, the water-level control apparatus include the valve body 32 of cavity in, valve element 34 and float
Son 36, the water inlet 320 of the upper end of valve body 32 is connected with the delivery port 14 of the case that adds water, and the delivery port 322 of valve body lower end extend into
In storage tank 20;Valve element 34 is movably set in the middle cavity of valve body 32, and valve element external diameter is less than middle cavity inside diameter, the top of valve element
Cooperation can be mutually sealed with the water inlet of valve body, valve body is extended in the bottom of valve element, and the bottom of valve element is connected with an elastomer 40, bullet
The other end of gonosome is connected with float 36.Elastomer is in compression spring, compressible elastic caoutchouc, compressible flexure strip
One kind, following examples are illustrated using compression spring.
With reference to Fig. 1-Fig. 4, the compression spring 40 is located at the center of valve element bottom, the compression with the junction of valve element
Spring is located on the axis of the top surface of float with the junction of float, therefore during float floats and declines, compression
Be not in the situation of distortion when spring is in normal stretch or compressive state, therefore float is bigger to the active force of valve element,
Therefore the active force to valve body of valve element is also stronger, it is easier to realizes the automatic watering of the automatic water-feeding device and stops the effect for adding water
Really.As Figure 1-Figure 4, float and valve element are lever connection, the junction of compression spring and float not in the centre of float, and
It is the right for being in float, therefore float, due to the factor of lever, the active force to valve element is bigger, therefore it is easier band movable valve plug
Raising and lowering.Preferably, an extending column 16 is added on the bottom surface for adding water case 10, the length that extending column 16 extends is big
In the length of valve body, a connecting rod 18 is connected with the bottom of extending column 16, one end of connecting rod 18 is hinged on extending column 16
Bottom, the other end is fixed on float 36, and the connecting rod is located on the axis of float with the tie point of float, the connection
Bar is located on the extended line of float axis with the pin joint of extending column, therefore float always is effect to the active force of valve element
In the center of valve element, thus valve element on valve body with when float rises or declines, always in the perpendicular direction
Motion, is not in deflection or inclined situation.In order to increase the contact area of valve element and valve body, strengthen obturation effect, institute
It is the conical surface to state valve element and the water inlet of valve body and mutually seal the face of cooperation, and the top of valve element is the conical surface.
With reference to Fig. 3 and Fig. 4, it is preferred that when valve element 34 blocks the water inlet of valve body 32, compression spring is in compression shape
State.When being added water in toward the case 10 that adds water, because the water level of storage tank is low, float is naturally drooped due to the effect of gravity, valve
Core does not also block valve body, and water is flowed into storage tank along the direction of arrow in Fig. 3;With gradually rising for water level, float
Son is gradually increasing also with water level, drives valve element toward rising, when due to adding water, continuous the going out from the valve body of eminence of water
The mouth of a river 322 is flowed into storage tank 20, and float can constantly be rocked with the change of the water surface, and now depositing due to compression spring
The oscillating quantity of water can be absorbed in the elastic force of, compression spring so that valve element is in a state for stabilization, without with float
Vibrate always, valve element and valve body will not also be constantly in Frotteurism, increased the sealing and service life of valve element and valve body.
With reference to Fig. 4, when no compression spring, when float is directly connected with valve element, when water level is added to water level position II,
The top surface of valve element just mutually seals cooperation with valve body, is not being added water.And the automatic water-feeding device in the application due to float with
Valve element is directly also associated with compression spring, due to the reaction force that the continuous compression of compression spring is produced, the water level in storage tank
When reaching water level position I, valve body can just be blocked higher than without the valve element of water level position II in the presence of compression spring, its water outlet high
Position number the elasticity of compression spring can be adjusted to adjust.When identical, water consumption in storage tank, due to compression spring pressure
After the amount of the reaction force produced during contracting, only water level decreasing exceedes water level position II, valve element can just be separated with valve body, then open
Beginning is added water.After as long as considerably less a part of water is consumed in existing automatic water-feeding device storage tank, will start automatic
Add water, stop adding water again after adding minimal amount of water, therefore humidifier is when work, valve element can continuous raising and lowering,
Valve element and the contact surface of valve body is constantly rubbed, reduce sealing effectiveness, reduction of service life;And that the utility model is provided
Automatic water-feeding device is planted, can just start automatic watering to a certain extent in water level decreasing, rather than so frequently, be thus provided that
The service life of valve element.
With reference to Fig. 5, because float is located at below the delivery port of valve body, therefore when adding water, water can always impact floating
Son, therefore the burden of compression spring can be increased, in order to reduce impact of the water to float, in the float in the water outlet positioned at valve body
One is additionally provided with the underface of mouth and crosses aquaporin 360, when adding water, water can enter into water storage by crossing aquaporin 360
In groove, without directly impacting float, therefore float is in relatively more stable state, and compression spring will not be impacted.
The utility model additionally provides a kind of humidifier of upper water-feeding, the automatic water-feeding device of the humidifier be it is above-mentioned from
Dynamic water controller.
Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should
This is understood, not departing from the spirit and scope of the present utility model that appended claims are limited, in form and details
On the utility model can be made a variety of changes, be protection domain of the present utility model.
