Description
Affiliated technical field
The utility model relates to technical field of drinking water treatment, relates in particular to a kind of float-controlled valve formula filter core exhaust apparatus.
Background technology
Special water purifier for drinking machine has been the product that generally uses, though it is of a great variety, but version mainly comprises the float-controlled valve of raw water box (also deserving to be called bucket), one or several filter core, clear water tanks (also claiming following barrel) and control water dispenser bucket middle water level etc., and its core is a filter core.
Can the gas in the filter core reliably discharge, and can be directly connected to filter core normally move.
The filter core exhaust structure of known technology has:
1. adopt the blast pipe exhaust that makes progress, as the exhaust structure in the Chinese patent " multifunction combined filter element of water purifier " (patent No. is 200520116399.6).The advantage of this structure is: exhaust is reliable.Its shortcoming is: a. moulding aspect is not too attractive in appearance, and for household products, aesthetic also is vital; B. in the air-flow of discharging, carry the globule or steam bubble sometimes, because blast pipe is communicated with the filter core inner chamber, sometimes in the blast pipe even leak pollutant or powder water treatment material in the water outlet, polluted water.
2. adopt the exhaust stop water that comprises exhaust hole and form of film, as the exhaust structure in the Chinese patent " modified Hydrocone type water purifien " (patent No. is 03209867.7).This exhaust structure is actually a check valve, promptly allows the gas in the filter core upwards to discharge by exhaust hole, does not allow current to flow downward by aperture, and this exhaust apparatus is located at the top of filter core.The advantage of this structure is: the moulding better appearance, the gas in the filter core can be discharged.Its shortcoming is: exhaust is unreliable, and the sealing that in fact is exactly film and exhaust hole is unreliable.One of its reason is the pollutant of the sealing surface of check valve in sooner or later can connate water; Former two is the film distortion of can wearing out therefore, and both all cause sealing unreliable.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of float-controlled valve formula filter core exhaust apparatus at the deficiency of above-mentioned prior art present situation.Be provided with filter core of the present utility model, mainly be used on the special water purifier for drinking machine, also can be used on other similar water purifier, on desk-top or vertical water purifier.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of float-controlled valve formula filter core exhaust apparatus, it comprises float and valve body, valve body is provided with the exhaust hole that diameter is not more than 3 millimeters, float under the exhaust hole is provided with the convex cone that can aim at exhaust hole when float floats, the filter core top shell is provided with upwardly extending short tube, and valve body and this short tube are tightly connected.
Being tightly connected of described valve body and short tube, it can adopt fixed seal connection, also can adopt slipper seal to connect.
The situation that adopts slipper seal to be connected for valve body and short tube: but the groove of fitting tight circle can be set, the sealing ring that the interior setting of groove can be carried out slipper seal with the madial wall of short tube on valve body; Also can make valve body, make the direct and short tube madial wall realization slipper seal of valve body with elastomeric material.Then, being provided with above valve body to move upward to valve body carries out spacing nut, and nut is provided with the exhaust passage, and nut and short tube are by being threaded.
Adopt the situation of fixed seal connection for valve body and short tube: valve body can adopt screw thread to fixedly connected with short tube; It is fixedly connected to adopt bonding way to carry out; Also valve body and short tube can be made integral structure, promptly valve body, short tube and filter core top shell are parts, and in other words, valve body and short tube are the parts of filter core top shell.
Convex cone and float can be made independent part respectively, and fixedly are assemblied in convex cone on the float; Convex cone and float also can be made an one-piece parts.
The gas in the filter core during filter core operation, has gas, because the density of gas is low, rise to the filter core top naturally, and float sinks naturally under the gravity effect, makes convex cone leave exhaust hole, so will upwards be discharged from exhaust hole if filter core is inner.As long as have gas in the filter core, then above-mentioned exhaust process is just carried out naturally.Along with the continuous discharge of gas, the water level in the filter core will constantly rise, when water level rises to when enough high, float will begin to rise, and the convex cone on the float will be closed exhaust hole at last gradually near exhaust hole, at this moment the gas in the filter core drains substantially, and filter core begins normal operation.
Described float is meant to have the part that can produce enough buoyancy in water.It can be that the bottom is uncovered, the shelly part of top seal, can be surperficial totally enclosed hollow parts (for example ball float), also can be the solid part of density extremely low (obviously low) than the density of water, or the solid part that adopts the inner material that contains a lot of mutual disconnected holes to make.
The beneficial effects of the utility model are: adopt filter core of the present utility model, its exhaust resistance is little, and exhaust is reliable, help filter core and normally move, and the exhaust apparatus shape is attractive in appearance.
