Specific embodiment

The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical Novel protected range.

It is specially the wastewater valve being applied in water purifier according to the valve in the present embodiment.It is used in prior art water purifier Wastewater valve mostly uses conventional use of valve, wherein realizing that throttling function is the throttle orifice being provided in valve chamber 11, to realize section Function is flowed, the size of throttle orifice is smaller, since it is simple with structure, the low advantage of manufacturing cost, and then in many necks It is widely used in domain as throttle valve.But conventional use of valve is applied and is used in water purifier as wastewater valve When, utility model people has found the problem of valve is easy to appear blocking, and abnormal rise occurs in the RO film pressure being embodied in water purifier Height, the reason is that since the inorganic salt content in water purifier in waste water is much higher than light water, therefore conventional use of valve is in water purifier It is middle as wastewater valve use its throttle orifice be easy because the growth of inorganic salts nucleus results in blockage, influence water purifier normal function.

In this regard, as shown in Figure 1 to Figure 3, including: valve body 10 according to valve provided in this embodiment, forming valve chamber 11, valve chamber There is the water outlet 111 being in communication with the outside in 11；Spool 30, in valve chamber 11；Wherein, valve body 10 further includes being molded over valve chamber Throttling chamber 13 in 11 has the water inlet 131 that is connected to of the external world with valve, and the throttling being connected to valve chamber 11 in the chamber 13 that throttles Mouthfuls 132, spool 30 is movably mounted on valve body 10, and has the throttle position for blocking restriction 132, in throttle position, Spool 30 has towards the pressing force in throttling chamber 13, and then the valve in the present embodiment, when being throttled, water passes through water inlet 131 enter throttling chamber 13, need to overcome the pressing force of the generation of spool 30, could pass through restriction 132 and enter valve chamber 11 and lead to The discharge of water outlet 111 is crossed, in the process, the realization of restriction effect is to intake by overcoming pressing force to realize without controlling The size of mouth 131, restriction 132 and water outlet 111, and then solve or at least alleviate valve because blocking up caused by inorganic salts growth Plug problem ensure that the normal realization of water purifier function.

Spool 30 can be towards the pressing force in throttling chamber 13 and be provided using the gravity that spool 30 carries.In the present embodiment In, valve further includes the bias piece being arranged between spool 30 and valve body 10, and in the throttle position of spool 30, pressing force is by bias piece Biasing force, the gravity of bias piece and the gravity of spool 30 provide, and then according to valve restriction effect to be achieved, specific aim The biasing force that bias piece is provided be adjusted, and then the valve of different restriction effects can be obtained, avoid blockage problem Meanwhile the better adaptability of valve, different waste water ratios can be obtained in water purifier.

With further reference to Fig. 2 and Fig. 3, the mounting hole 15 extended along the vertical direction is formed on the valve body 10 of the present embodiment, Spool 30 is movably disposed in mounting hole 15, and the bias piece in the present embodiment is specially to be mounted in mounting hole 15, one end It is abutted with valve body 10, the spring 20 that the other end is abutted with spool 30, in the throttle position of spool 30, pressing force can be spring 20 The gravity for being applied to the elastic force of spool 30, the gravity of spring 20 and spool 30 provides.

In a variant embodiment in the present embodiment, bias piece is also that one end is abutted with valve body 10, the other end and valve The homopolarity magnetic element that core 30 abuts provides biasing force to spool 30 using the principle that magnet at the same level repels each other.

As shown in Figures 2 and 3, it is preferable that the valve in the present embodiment further includes the block head 31 being molded on spool 30, The throttle position of spool 30, block head 31 are abutted with restriction 132 to block restriction 132, and block head 31 is silica gel head, in circle Taper, and then the block head 31 in the throttle position of spool 30, spool 30 and restriction 132 cooperate and obtain good throttling Effect, more preferably, for valve while being not easy to plug, the service life is longer for the reliability in throttling process.

It in practical manufacturing process, can be split settings between block head 31 and spool 30, be also possible to be integrally formed.

Specifically, the valve in the present embodiment is specially solenoid valve, and valve further includes the electricity for being molded over 15 circumferential direction of mounting hole Magnetic coil 16.In power-up state, spool 30 is in recoil state, and the spool 30 in mounting hole 15 is by electromagnetic coil 16 at this time Active force overcomes the elastic force of self gravity and spring 20, moves up and opens restriction 132, and water enters from water inlet 131 to be throttled Then chamber 13 enters in valve chamber 11 from open restriction 132, by 111 process valve of water outlet in valve chamber 11 outside, at this Water flow not will receive the resistance of spool 30 by restriction 132 in the process, and valve has no restriction effect, install the water purifier of valve at this time In bath state.In power-down state, the block head 31 in mounting hole 15 on spool 30 is in 30 gravity of spool, the bullet of spring 20 It is abutted under the action of the pressing force that the gravity of power and spring 20 generates jointly and blocks restriction 132, water enters from water inlet 131 Throttle chamber 13, needs to overcome the effect of pressing force to flow out from restriction 132, and valve has an expenditure and pressure effect in the process Fruit, the water purifier for installing valve at this time are in water state processed.

The present embodiment also provides a kind of device with valve, including valve as described above, and then excellent possessed by above-mentioned valve Point, the device with valve in the present embodiment should also have, and details are not described herein.

Device in the present embodiment with valve can be water purifier, purifying drinking appliance etc..

Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or It changes among the protection scope created still in the utility model.
