Abstract
A spraying pump with an external spring and capable of being used reversely comprises the following components: a nozzle, a pump barrel, a threaded cover, a piston bracket, a piston, a return spring, a suction pipe and a ball valve core. The lower part of the pump barrel is provided with a suction pipe interface. The spraying pump further comprises the following components: a valve plate which is made of flexible material, a valve plate seat and a ball valve seat. The valve plate comprises a central plate and a base. Through liquid holes which are arranged annularly are provided between the central plate and the base. The valve plate is equipped on the valve plate seat. The central plate is matched with a liquid outlet hole of the pump barrel. The ball valve core is equipped on the ball valve seat on the pump barrel. The ball valve core is matched with the liquid outlet hole. An annular flange on the valve plate is matched with a window on the pump barrel. Because the structure is adopted, the ball valve core can not be separated from the liquid outlet hole in reverse use, and the negative pressure in the pump barrel is furthermore enlarged until the negative pressure can open the sealing between the annular flange of the valve plate and the window of the pump barrel. The liquid enters the pump barrel, and liquid is sprayed out from the nozzle. The spraying pump overcomes a defect of incapability of spraying liquid when the spraying pump can not be reversed according to the prior art.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1; A kind of external spring and can be inverted the atomizing pump of use; Comprise shower nozzle 1, pump barrel 2, thread lid 3, piston holder 4, piston 5, return spring 6, suction pipe 7 and ball valve core 8; Suction pipe interface 21 is arranged at said pump barrel 2 bottoms, also comprises the interior ball valve seat of valve block 9, the valve block seat that is arranged on fluid hole 22 places on pump barrel 2 inner bottom platings and suction pipe interface that a flexible material is processed, and piston holder 4 directly is connected with shower nozzle 1.
As shown in Figure 3, said valve block 9 comprises centre slice 91 and pedestal 92, between centre slice 91 and the pedestal 92 liquid-through hole that is circular arrangement is arranged, and valve block 9 is arranged on the valve block seat, and centre slice 91 cooperates with fluid hole 22; Ball valve core 8 is arranged on the ball valve seat on the pump barrel 2, and ball valve core 8 cooperates with fluid hole 22; Fluid hole 22 is truncated cone.
As shown in Figure 2, said valve block seat is the cannelure 23 around fluid hole 22;
As shown in Figure 4, pedestal 92 lower axial end of said valve block 9 have ring interface 93, and ring interface 93 is chimeric with cannelure 23.
The annular folding is upwards arranged along 94 the week of the pedestal 92 of said valve block 9;
Institute's pump barrel 2 has window 24 with the intersection of the base plate of pump barrel 2, and the annular folding cooperates with window 24 along 94.
Annular protrusion is arranged at the top of the inwall of said cannelure 23, on the inwall of said ring interface 91 annular protrusion is arranged, and the annular protrusion on ring interface 91 inwalls is positioned at the cannelure 23 of bottom of the annular protrusion of cannelure 23.
As shown in Figure 2, said ball valve seat is made up of with the strong point 212 that is positioned at axial projection 211 bottoms the axial projection 211 that is positioned on suction pipe interface 21 inwalls;
Said ball valve core 8 cooperates with the strong point 212 and axial projection 211.
As shown in Figure 5, there is a bending part 51 said piston 5 upper ends, and the angle of bent plate position 51 and matrix is more than or equal to 90 degree, and bending part 51 is less than other wall thickness everywhere of piston.
When pressed by external force shower nozzle 1, shower nozzle 1 moves down return spring 6 compressions, piston holder 4 pistons 5.Fluid hole 22 on the centre slice 91 corresponding pump barrels 2 of valve block 9, the annular folding edge 94 of valve block 9 and window 24 through holes on the pump barrel 2, sealing position, two places all is in closed condition.Pump barrel 2 internal pressures increase, and impel that bending part 51 deforms on the piston 5, crumple, thereby open the passage between piston 5 and the piston holder 4, and pump barrel 2 interior air or liquid spray at a high speed through piston holder 4 centre bores, shower nozzle 1 centre bore.After air or fluid pressure in the pump barrel 2 reduced, original shape was recovered at bending part 51 places on the piston 5, the passage between closure piston 5 and the piston holder 4.
During forces on being applied to shower nozzle 1, return spring 6, shower nozzle 1, compression piston 5, piston holder 4 reset.Passage between piston 5 and the piston holder 4 is in closed condition at this moment, so pump barrel 2 inside present negative pressure state.Two kinds of situation appear this moment:
When (one) forward used, ball valve core 8 did not seal between ball valve core 8 and the fluid hole 22 in the bottom of ball valve seat.The centre slice 91 of valve block 9 can at first be opened; Liquid gets into pump barrel.
(2) be inverted when using, ball valve core 8 is rolled to fluid hole 22, produces sealing between ball valve core 8 and the fluid hole 22, and ball valve core 8 can not be separated with fluid hole 22; Negative pressure further increase in the pump barrel 2, the sealing between the window 24 of annular folding edge that is enough to open valve block 9 and pump barrel 2, and liquid gets into pump barrel 2.
Above-described only is the preferential embodiment of the utility model.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the utility model principle, can also make some improvement and modification, this also is regarded as the protection domain of the utility model.
