Abstract
The utility model discloses a flow switching device. The flow switching device comprises a valve body which is provided with a normally-open water flow channel and a normally-closed water flow channel in the axial direction, a switching device body arranged in the downstream direction of vertical water flow comprises a valve carrier and a switching shaft, the valve carrier is arranged in the direction of the vertical water flow, and the switching shaft can slide in a reciprocating mode in the valve carrier. The switching shaft comprises a large end and a small end, the small end is connected with a button and stretches out of the valve body, and the large end abuts against an elastic part arranged in the valve carrier. When the flow switching device is in a natural state, the switching shaft is kept at a first position by means of elastic force of the elastic part on the switching shaft, and the large end of the switching shaft stops water flow of the normally-closed water flow channel. When the button is pressed in a touched mode, the switching shaft is moved to a second position, the normally-closed water flow channel is opened, water from the normally-closed water flow channel flows through space between the large end and the small end of the switching shaft, and differential pressure of the water flow between the large end and the small end overcomes the elastic force of the elastic part to make the switching shaft be kept at the second position. The switching shaft can keep at the second position, and therefore using convenience is achieved.

This switching shaft is blocked the current of normally closed flow channel when primary importance, and current only can pass through from the flow channel of often opening, and now the water-outlet quantity of this flow shifting device is little; When this switching shaft moves to the second place, normally closed flow channel is opened, current pass through from the flow channel often opened and normally closed flow channel simultaneously, now the water-outlet quantity of this flow shifting device is large, and, the elastic force that the pressure reduction of current between large end and small end overcomes elastic component makes switching shaft be kept at the state of the second place, does not need artificially to press for a long time this ammonium button, easy to operate.And after cutting off the water supply, this elastic component can make this switching shaft reset, and again blocks this normally closed flow channel, make at every turn when water flowing is used, this flow shifting device is all in small flow state, has advantages of the water saving of pressure.
Among one preferred embodiment: the sidewall of this valve seat is provided with the first opening and the second opening, this first opening is communicated with the entrance of the current of normally closed flow channel, this second opening is communicated with the outlet of the current of normally closed flow channel, this second opening between this large end and this small end, this large end first opening described in shutoff when described primary importance.
Among one preferred embodiment: also comprise the water-saving piece of the upstream that is arranged on current, the middle part of this water-saving piece is provided with through hole, and the sidewall of this valve seat has outwards extended connecting passage, this connecting passage connects this first opening and this through hole.
Among one preferred embodiment: also comprise stopper, this stopper is connected to the lower end of this valve seat, this elastic component bullet withstands on this stopper.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 has illustrated the perspective exploded view of a kind of flow shifting device of the utility model.
Cross-sectional schematic when the normally closed flow channel that Fig. 2 has illustrated the flow shifting device shown in Fig. 1 is closed.
Cross-sectional schematic when the normally closed flow channel that Fig. 3 has illustrated the flow shifting device shown in Fig. 1 is opened.
Embodiment
Please refer to Fig. 1, a kind of flow shifting device of the present utility model, has advantages of water saving, adjusts water flow, automatically recovers small flow water outlet after cutting off the water supply.Described flow shifting device comprises a valve body 10, a water-saving piece 30, a COMM communication 50 and a stopper 70.
Please refer to Fig. 1 to Fig. 3, this valve body 10 is provided with a Chang Kaishui circulation road 12 and a normally closed flow channel 14 vertically.This water-saving piece 30 is placed in this valve body 10 and is arranged on the upstream of current.The middle part of this water-saving piece 30 is provided with a through hole 32.
This COMM communication 50 is arranged on the downstream direction of the current of vertical this valve body 10.This COMM communication 50 comprises valve seat 52, a switching shaft that can reciprocatingly slide in valve seat 52 54, a button 56 and the elastic component 58 that a Transverse to the flow direction is set up.This valve seat 52 is one-body molded with this valve body 10.The sidewall of this valve seat 52 is provided with one first opening 522 and one second opening 524, and this first opening 522 is communicated with the entrance of the current of normally closed flow channel 14.This second opening 524 is communicated with the outlet of the current of normally closed flow channel 14.The sidewall of this valve seat 52 has outwards extended a connection channel 526, and this first opening 522 is positioned at this connecting passage 526, and this connecting passage 526 connects this first opening 522 and this through hole 32.Described switching shaft 54 has large end 542 and one small end 544.This second opening 524 is between this large end 544 and this small end 542.This small end 542 connects this button 56 and protrudes upward outside valve body 10.This stopper 70 is connected to the bottom of this valve seat 52.This elastic component 58 is located in valve seat 51, and these elastic component 58 bullets withstand between this stopper 70 and this large end 544.
During nature, the elastic force of 58 pairs of switching shafts 54 of elastic component makes switching shaft 54 move up and remain on primary importance, now, the current of the normally closed flow channel 14 of large end 544 blocking-up of switching shaft 54, i.e. the first opening 542 described in these large end 544 shutoff, current only can pass through from the flow channel 12 of often opening.
When pressing button 56 downwards, switching shaft 54 is moved downward to the second place, normally closed flow channel 14 is opened, this large end 544 is opened this first opening 522, from the water of normally closed flow channel 14, between the large end of switching shaft 54 and small end, pass through, now, the elastic force that current overcome elastic component 58 at the pressure reduction of 542 of large end 544 and small ends makes switching shaft 54 be kept at the state of the second place, and current pass through from the flow channel 12 often opened and normally closed flow channel 14 simultaneously.
Understandably, after cutting off the water supply, the active force of this elastic component 58 makes this switching shaft 54 move to primary importance on again, closes this normally closed flow channel 14.
The above, it is only the utility model preferred embodiment, therefore can not limit according to this scope that the utility model is implemented, the equivalence of doing according to the utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that the utility model contains.
