When moving up reservoir module and pump assembly 16; Fin 292 on the neck 246 gets into the perforate 262 on the fixing clip 48; Each fin 292 moved the space 288 that forms between protruding 286, till the groove 282 that each fin 292 engages in the clip 48.When mobile stopping that container 60 makes progress, container 60 all turns on both direction, forces fin 292 to place the groove 282 of bump, adjacent 286.The fin 292 of a stop component 285 and a container 60 amplexiforms, and controls the rotation of container 60.Some or all convexity 286 friction surfaces are up exerted pressure to fin 292, to firmly fix container 60 and casing 16, still can remove owing to supporting component 14 appropriate the contact being arranged with motor housing.At this moment, projection 295 (Figure 27) can be arranged in the sawtooth 291 (Figure 21).

For with sky store assembly 16 from assembly 14 dismounting, container rotates on aforesaid opposite direction, up to fin 292 with till aliging in the interval 288 in the fixing clip 48.Then, reduce the position of container, shift out extruding pipe 68 in the passage 66 from nozzle 24, remove actuator 174 and pump assembly 65 from motor housing and supporting component 16.Then as previously mentioned, the whole assembly that stores is installed.A plurality of injection pumps activate, and (Figure 32) can take place automatically, upwards is promoted to extruding pipe 68 with the soap with initial amount from container 60.

In case correctly install, when the user was put into hand below the sawtooth leakage fluid dram 30 of nozzle 24, fluid extrusion system 10 just began to start.As previously mentioned, electronic eyes sensor 36 detects existence in one's hands, and sees a signal off and give actuator motor 49.Reducing gear train 51 driving pumps are hammered 53 clockwise directions into shape and are rotated (as shown in Figure 2); Thus, actuator arm 162,164 beginnings are moved (Figure 15 A) towards the flange 176 on the actuator 174; In the space 172 of the opening between the actuator arm 164,166 of the top part 190 entering pump hammers 53 of actuator.Actuator arm 164,166 engages with actuator flange 176 (Figure 15 B), and orders about actuator 174 move (shown in Figure 15 C) down.In illustrated embodiment, as just giving an example, actuator 174 moves 0.280 inch down.The moving down of actuator 174 caused elongated extruding pipe 68 identical distance of withdrawal in nozzle 24 and passage 66.In illustrated embodiment, in the position of shifting out, the pipe end 70 of extruding pipe 68 still remains on the outside of the nozzle opening 31 of nozzle 24.

When actuator 174 moves down under the influence of pump hammer, move even manage its retracted position of 68 forwards, also can extrude quantitative liquid soap from the tip 70 of elongated extruding pipe 68.With reference to Figure 20, in the illustrated embodiment, pump machanism 65 is self-starting pumps, before the pump machanism action, has been full of liquid soap in pump machanism and the extruding pipe 242.When actuator 174 moved down, pump machanism 65 forced liquid soap in the pump machanism to the upper reaches, and compression spring 236.

Bulb stopper

206 and 232 moves up, and causes extra liquid soap to be upward through inlet tube 242, gets in the cell 218 through bulb stopper 232.Bulb stopper 206 rises, when the platform 204 of bulb stopper 206 and time Control Shaft 196 amplexiforms, it make progress move and just be limited.

When pump hammer 53 its restriction sites that clockwise rotate of arrival, motor 49 stall, spring 236 (Figure 20) forces pump machanism 65, actuator 174 and extruding pipe 68 to move up, and makes liquid soap be full of pump machanism 65 and extruding pipe 68.Bulb stopper 206 moves on on the closed position on the hole 214.Bulb stopper 206 moves on to 216 time spents of V-shaped groove from platform 204, has determined the dosage of pump machanism 65 dispensing soap in once moving.

With reference to Figure 18, when pump machanism 65 dispensing soaps, liquid soap also centers on the time Control Shaft 196 of actuator 174 through perforate 202.

After pump machanism 65 starts, along with pipe 68 towards nozzle 24 withdrawals, liquid soap is extruded from managing 68 end 70 with continuous flowing.As stated, when motor stall, the spring 236 (Figure 20) that during liquid soap is carried, has compressed makes that pump chamber 218 is expanded when extruding pipe is return the nozzle opening 31 in the nozzle 24.Pump chamber 218 expansions and extruding pipe action forward combine, and make that the liquid soap that does not also leave pipe end 70 is inhaled back when pipe 68 is return.This has just kept a string liquid soap in pipe 68, not so these liquid soaps will drip after main fertilizer soap lye conveying function is accomplished.This mode of operation also can prevent to extrude between the device dropping liquid and raffinate accumulation using and clean liquid soap.
