Description

A kind of hand sprayer pump

Technical field

The utility model is related to a kind of hand sprayer pump.

Background technology

In agricultural atomizer field, common membrane pump, such as notification number are special for CN2687374Y Chinese utility model A kind of sprayer air chamber-rod split membrane pump of profit, it includes pump, stopper rod, air chamber, cylinder body, water intaking valve, delivery port and gone out Water valve, stopper rod top is provided with linkage connector, and the inside of cylinder body is provided with diaphragm and barrier film pallet and is connected with the lower end of stopper rod, The edge of diaphragm is compressed by cylinder body, and cylinder body passes through connecting tube and gas connection.

, it is necessary to by pulling stopper rod, the outer bar wall and pump of stopper rod up and down during stating membrane pump in actual use Contact area between inner tube wall is larger and can produce stronger frictional force between the two, more laborious during its pulling stopper rod.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of hand sprayer pump, its It is more laborsaving during promotion.

Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of hand sprayer is used Pump, including diaphragm body, gas hood, in addition to the seat of honour, the lower seat positioned at seat of honour bottom, the diaphragm body be installed on the seat of honour and lower seat it Between, the gas hood covers above the seat of honour and installation sheet, the installation sheet and barrier film is provided with inside fluid reservoir, the seat of honour for being formed Transition chamber is formed between body, the installation sheet, which is provided with to be provided with the first inlet opening, first inlet opening, can limit fluid reservoir Interior liquid enters the one-way water outlet valve of transition chamber；Seat of honour side wall is provided with the intake tunnel communicated with transition chamber and storage In the exhalant canal that liquid room is communicated, the intake tunnel the unidirectional of intake tunnel is entered provided with the liquid that can be limited in transition chamber Water intaking valve；The lower seat is provided with driving rack, drive gear, the power input lever for driving drive gear to rotate, driving Rack sliding is connected to lower seat and end is connected to diaphragm body, and drive gear is meshed and promoted on driving rack with driving rack Lower sliding motion.

By above-mentioned technical proposal, power input lever carries out positive and negative rotation, and power input lever drives drive gear to be revolved Turn, driving rack is pumped, diaphragm body can also followed by driving rack and be moved up and down, when diaphragm body is downward During pulling, the liquid in intake tunnel can be entered in transition chamber by one-way water inlet valve, when diaphragm body is pushed up, transition Indoor liquid can be entered in fluid reservoir by one-way water outlet valve, if exhalant canal is remained in closed state, fluid reservoir Pressure can be increasing, when exhalant canal once opening, the liquid in fluid reservoir will directly spray；Above-mentioned motion process In, resistance is produced when first, farewell traditional manual sprayer piston formula leather cup oil-free or expansion, the outer bar because of stopper rod is it also avoid The powerful frictional force that wall occurs sliding friction with pump and produced is durable in use；Secondth, due to the power center (PC) position of drive gear In drive gear medium position, the impetus between drive gear and driving rack is in meshing point between the two, power The heart and the distance between meshing point are shorter, and use is more laborsaving.

It is preferred that, in addition to stay, lock-screw, the stay fit in the upper side wall of diaphragm body, the driving Rack end is mutually butted on the lower wall of diaphragm body, and the lock-screw is through stay and is threadedly connected to driving rack end.

By above-mentioned technical proposal, whole hand sprayer with pump in actual use, power input lever can be continuous Ground positive and negative rotation, the setting of bushing repeatedly, is avoided that power input lever is directly contacted with supported hole aperture, inputs power There is bushing between bar and supported hole aperture, the generation of abrasion can be greatly reduced, even if wearing and tearing, most abrasion Can occur on bushing, bushing is changed.

It is preferred that, it is arranged with sealing ring on the lower seat lateral wall.

By above-mentioned technical proposal, during actual installation, mounting hole is set on spray enclosure, whole spray manually Day with fog pump, which directly coordinates, to be inserted into mounting hole, now, and sealing ring can directly be contradicted with the hole wall of mounting hole, and can be significantly Sealing between erection ＆ lift hole hole wall and lower seat lateral wall, reduces sprayer internal liquid outside mounting hole hole wall and lower seat Flowed out between the wall of side.

It is preferred that, in addition to the outlet pipe of exhalant canal is socketed on, the lower seat is provided with the pipe for being used for clamping outlet pipe Folder.

By above-mentioned technical proposal, there is larger interior pressure in fluid reservoir, when the switch of outlet pipe is opened, positioned at storage Liquid in liquid room by pressurization directly can be gone out out of outlet pipe, and outlet pipe itself can produce rocking by a relatively large margin, water outlet Pipe sleeve is connected to exhalant canal, and rocking for outlet pipe will certainly reduce the connective stability with exhalant canal；The setting of pipe clamp, then can Positioning clamping directly is carried out to outlet pipe, the amplitude of rocking of outlet pipe is greatly reduced, between reduction outlet pipe and exhalant canal The probability departed from.

It is preferred that, the one-way water inlet valve is included on the water inlet valve body for being threadedly connected to intake tunnel, the water inlet valve body Provided with the second inlet opening, the water inlet valve body is outward extended with water inlet pipe.

By above-mentioned technical proposal, the setting of water inlet pipe can meet the absorbent function of low water level；I.e. ought water level position be absorbed water When under the second inlet opening hole position, water inlet pipe can be directly protruding into after water level to be absorbed water, and water directly can be inhaled from water inlet pipe Enter.

It is preferred that, the one-way water inlet valve is included on the water inlet valve body for being threadedly connected to intake tunnel, the water inlet valve body Provided with the second inlet opening, water inlet valve body is provided with the second polygon groove being connected with the second inlet opening away from the end of transition chamber.

By above-mentioned technical proposal, according to actual installation situation, corresponding plane water suction, i.e. the second inlet opening can be carried out neat Flat or less than position absorb water, the liquid on position to be absorbed water is understood directly be entered in intake tunnel by the second inlet opening；Installing During, external polygon spanner can be directly inserted into the second polygon groove, turn polygon spanner, whole water inlet valve body It can rotate in a circumferential direction, water inlet valve body is during rotating in a circumferential direction, and water inlet valve body can easily be realized to be screwed with intake tunnel With release.

It is preferred that, in addition to screen pack, the screen pack is provided with flange, and the flange is mutually embedding with the second polygon groove Close and push against.

By above-mentioned technical proposal, the second polygon groove is reasonably make use of, when needing to fix screen pack.Flange is direct It is pressed into the second polygon groove, interference fit, screen pack is produced between the cell wall of the lateral wall of flange and the second polygon groove Just it can be fixed；Screen pack can then carry out, into water filtration, reducing the impurity level existed in sprayer to liquid, extend sprayer Actual life.
