Exhaust device for portable pressure sprinkler

The present invention relates to an "exhaust device for a portable pressure sprinkler", and more particularly to an exhaust device that can be arbitrarily inserted into an outlet pipe of a portable pressure sprinkler, which is contained in high-pressure water flowing through an outlet pipe. In the case of air, it can be completely eliminated immediately, thereby preventing the water pressure of the overall output from being intermittent or unstable.

The conventional hand-held pressure water jets disclosed in the prior art are, for example, US Pat. No. 7,110,850, US Pat. No. 5,303,866, and the Republic of China Invention No. I253421, etc., and their configurations are substantially the same, as shown in the first to third figures. The utility model mainly comprises a water spray gun 1, a portable water storage tank 2, a set of rechargeable battery 3 and a diaphragm booster pump 10, wherein the rechargeable battery 3 is a DC 24 volt power supply, and can directly utilize the automobile. The cigarette lighter switch holder is inserted into the charging, and is inserted into the bottom space of the portable water storage tank 2 together with the diaphragm booster pump 10, and the water inlet 11 of the diaphragm booster pump 10 and the portable water storage tank 2 The water outlets 20 are connected by an inlet pipe 4, and the water outlet 12 and the water spray gun 1 are connected by an outlet pipe 5, and a water injection port 21 is provided on the top surface of the portable water storage tank 2; Therefore, the main appeal function of the conventional portable pressure water sprayer is that it utilizes the portable water storage tank 2 to be free from the position of the water source, and can be moved to the outdoors by filling the interior with water through the water inlet 21 , placed side by side to clean the vehicle or thing After the peripheral position, the vehicle or the article can be washed and cleaned (as shown in the second figure); when the power is turned on to make the diaphragm booster pump 10 actuate, the water inlet 11 of the diaphragm booster pump 10 will First, the water W in the portable water storage tank 2 is sucked through the water outlet 20 and the water inlet pipe 4, and then pressurized to be discharged into the water outlet 12 by the high pressure water W', and the high pressure water is directly discharged by the water outlet pipe 5. W' is delivered to the water spray gun 1 to achieve the water pressure required for the flushing spray (as shown in the third figure).

However, there is a major loss in the operation of the aforementioned use. When the water storage capacity in the portable storage tank 2 is exhausted, another water must be re-injected, and the water inlet 11 connected to the diaphragm booster pump 10 is connected at this time. "Air" is stored in the water inlet pipe 4 between the water outlet 20 of the portable water tank 2, and when the diaphragm booster pump 10 is started again, the air remaining in the water inlet pipe 4 is mixed. The water enters the diaphragm booster pump 10, causing the water pressure output from the water outlet 12 to be intermittent or unstable, which not only causes the overall supercharging effect to be reduced, but also indirectly causes all components in the diaphragm booster pump 10 to be indirectly caused. In a state of unsatisfactory operation, under long-term use, an improper load on the diaphragm booster pump 10 is accumulated, and the service life of the entire portable pressure sprayer is further shortened.

Therefore, the inventor of the present invention actively studied the specific solution for how to exclude the "air" contained in the water, and succeeded in submitting the application of the Republic of China invention patent No. 096142614 (publication number 200912139), the specific The structure is as shown in the fourth and fifth figures, and is mainly provided with a venting seat 30 and a pneumatic piston seat 40 on the side wall of the water outlet 12 of the diaphragm booster pump 10; wherein the venting seat 30 is The hollow cylindrical body has a first exhaust chamber 31 and a second exhaust chamber 32 at a lower portion and an upper portion, and the inner diameter of the first exhaust chamber 31 is larger than the second exhaust chamber 32 and is mutually The first exhaust chamber 31 is connected to the side wall surface of the water outlet 12 of the diaphragm booster pump 10 and is provided with a vent 33, and the center of the top surface of the exhaust seat 30 faces the second exhaust chamber 32. A venting port 34 is further disposed; the pneumatic piston seat 40 is a hollow cylindrical body having an open end 41 on the top surface and a closed end 42 on the bottom surface, and the open end 41 is inserted into the second row of the exhaust seat 30. The inner diameter of the gas chamber 32 is smaller than the outer diameter of the closed end 42 and the closed end 42 is placed. In a discharge chamber 31, and corresponding to the position of the vent 33 of the venting seat 30, a compression spring 43 is reinserted toward the inside of the open end 41, and is adjacent to the side wall of the closed end 42. Two through holes 44 are formed in the upper portion, and a sealing ring 45 is disposed on the outer edge surface between the two through holes 44 and the closed end 42 (as shown in an enlarged view in the fifth figure).

The manner of actuation is as shown in the sixth and seventh figures. When the high pressure water W' in the water outlet 12 of the diaphragm booster pump 10 does not contain the air A, the pressure of the high pressure water W' is greater than that of the compression spring 43. The elastic force, therefore, the high-pressure water W' flowing through the water outlet 12 is synchronously introduced into the first exhaust chamber 31 of the exhaust seat 30 by the vent 33, and is applied to the closed end 42 of the pneumatic cylinder 40, and the whole The pneumatic cylinder 40 is completely pushed into the second exhaust chamber 32, and the through hole 44 located in the pneumatic cylinder 40 is also completely inserted into the second exhaust chamber 32 while sealing the ring 45. Adhering to the leak stop function, the high pressure water W' originally entering the first exhaust chamber 31 is forced to enter the second exhaust chamber 32, so all the high pressure water W' will be output from the water outlet 12 (such as the sixth). In the figure, the solid arrow is in the state of normal pressurized drainage; when the high pressure water W' contains air A, the pressure of the high pressure water W' is lowered to cause the compression spring 43 to be The elastic force is instead larger than the high pressure water W'. At this time, under the elastic force of the compression spring 43, the pneumatic cylinder is made The closed end 42 of the 40 begins to extend forward into the first exhaust chamber 31, and simultaneously causes the two through holes 44 to also enter the first exhaust chamber 31. Therefore, the air A contained in the high pressure water W' It will enter the first exhaust chamber 31 along the vent 33, enter the pneumatic piston seat 40 via the two through holes 44, and finally discharge the diaphragm through the open end 41 and the exhaust hole 34 of the exhaust seat 30. Outside the pump 10 (as indicated by the dashed arrow in the seventh figure) and achieve the effect of exhaust; after all the air A is discharged from the diaphragm booster pump 10, the pneumatic piston seat 40 in the exhaust seat 30 will be re-applied The elastic force of the compression spring 43 is pushed into the second exhaust chamber 32 and returned to the position of the normal pressurized drainage (as shown in the sixth figure).

The aforementioned Republic of China invention patent No. 096142614 has indeed achieved the expected effect of "exhaust" after actual mold opening, but another defect was found during the test, and its occurrence is as shown in the eighth figure. When the booster pump 10 is not activated, the pneumatic piston seat 40 is subjected to the elastic force of the compression spring 43, so that the closed end 42 completely abuts against the vent 33 of the exhaust seat 30. Air A is already stored in the air, and after the diaphragm booster pump 10 is activated, the high-pressure water W' in the water outlet 12 is filled with air A, and the pressure of the high-pressure water W' is lowered and smaller than that of the compression spring 43. The elastic end, so the closed end 42 of the pneumatic piston seat 40 can not be pushed away from the vent 33 of the exhaust seat 30 (as indicated by the dashed arrow indicated in the position of the vent 33 in the eighth figure), resulting in high pressure water W' The air A cannot be smoothly discharged, and if this condition is not improved, the effect of the exhaust gas is greatly reduced and is not satisfactory, and the present invention is still further proposed.

The inner center of the inner cover is provided with a venting hole 61, an air flow passage 62 and a circle respectively from the top surface to the bottom surface. a groove 63 and a female thread 64, wherein the vent hole 61 and the gas flow passage 62 penetrate each other, and the air flow passage 62 and the circular groove 63 penetrate each other, and the inner diameter of the circular groove 63 is larger than The inner diameter dimension of the air flow passage 62, the inner diameter dimension of the air flow passage 62 is greater than the aperture dimension of the exhaust hole 61; a compression spring 80, the plug is placed in the air flow passage 62 of the outer cover 60, the inner diameter of the spring ring is smaller than the maximum outer diameter of the movable push block 90; and a movable push block 90 is placed on the body 50 The hollow exhaust chamber 54 is made of a material having elastic softness, and the bottom portion 91 is flat and the top portion 92 is a conical surface of a conical surface, and a plurality of legs of equal length are protruded from the bottom surface of the circumference of the bottom portion 91. Column 93.

The combination is quite simple. As shown in the tenth to twelfth drawings, the bottom 91 of the movable push block 90 is first directed toward the exhaust seat 52 of the body 50, and the hollow exhaust chamber of the exhaust seat 52 is placed. 54, and the foot post 93 is placed on the bottom surface 55 of the hollow exhaust chamber 54, and the compression spring 80 is placed in the air flow passage 62 of the outer cover 60, and the spring loop of the last turn of the end is made. And placed against the conical surface top 92 of the movable push block 90, and finally the outer cover 60 is biased close to the contact exhaust seat 52, and then rotated to screw the female screw 64 onto the male thread 53 of the exhaust seat 52. The completion is completed (as shown in the eleventh and twelfth figures), and the bottom portion 91 of the movable push block 90 and the vent 56 of the inner body 51 of the body 50 are separated by the leg 93. There is a section equal to the height of the leg 93 (as shown in Fig. 12).

The above-mentioned installation, use and actuation modes of the present invention are as shown in the ninth and twelfth to fifteenth drawings. First, the cutting is selected at any position of the outlet pipe 5 to form two outlet pipes. 5a and 5b (as shown in the ninth figure), the two end nozzles of the body 50 are respectively forcefully inserted into the two outlet water pipes 5a and 5b, that is, the assembly with the portable pressure water sprayer is completed (such as the tenth When the high pressure water W' in the water outlet 12 of the diaphragm booster pump 10 does not contain the air A, the pressure of the high pressure water W' is greater than the elastic force of the compression spring 80, so that it enters through the water outlet 12. The high-pressure water W' in the water pipe 5b enters the hollow exhaust chamber 54 of the exhaust seat 52 from the vent 56 of the body 51 of the body 50, and is simultaneously applied to the bottom 91 of the movable push block 90. The top surface 92 of the entire movable push block 90 is pushed into the air flow passage 62 of the outer cover 60 completely, and the entire inlet of the air flow passage 62 and the circular groove 63 is completely in close contact with each other. And the function of stopping the leak (because the soft material of the movable push block 90 has elasticity, it can be combined with the outer cover of the rigid material When the seats 60 are closely attached to each other, the effect of preventing leakage is generated, and the high-pressure water W' originally entering the hollow exhaust chamber 54 can no longer enter the airflow passage 62, so all the high-pressure water W' will be completely from the body. The inner portion 51 of the 50 pipe body is outputted to the other water outlet pipe 5a to reach the water spray gun 1 (as indicated by the solid arrow in the thirteenth figure and its enlarged view), and the state of the normal pressurized drainage is in the case of this operation. .

When the air contained in the high-pressure water W' contains air A, the pressure of the high-pressure water W' is lowered, and the elastic force of the compression spring 80 is rather greater than the high-pressure water W'. At this time, under the elastic force of the compression spring 80, the activity is caused. The push block 90 moves toward the bottom surface 55 of the hollow exhaust chamber 54 and is not in close contact with the air flow passage 62 to form a gap. At this time, the air A contained in the high pressure water W' is formed. After passing through the vent 56, it enters the hollow exhaust chamber 54 and penetrates the gap between the springs of the compression springs 80 along the top 92 of the movable push block 90 to enter the air flow passage 62, and finally passes through the exhaust hole 61. The air A is discharged out of the outer cover 60 (as shown in the fourteenth figure and the direction indicated by the dotted arrows in the figure), so that it has the effect of exhausting; all the air A is discharged out of the outer cover 60 Thereafter, since the pressure of the high pressure water W' is again greater than the elastic force of the compression spring 80, the conical surface top 92 of the movable push block 90 is again pushed completely into the air flow passage 62 of the outer cover 60, and again The entire inlet of the air flow passage 62 is formed in a state of being completely in close contact with each other, and Return to the state (as shown in FIG XIII) during normal pressurized drainage.

When the diaphragm booster pump 10 is not activated, the movable push block 90 is subjected to the elastic force of the compression spring 80, so that the leg post 93 on the bottom portion 91 abuts against the bottom surface 55 of the hollow exhaust chamber 54. And spaced apart from the vent 56 of the body 51 of the body 50 by a distance equal to the height of the leg 93 (as shown in FIG. 12), if the high pressure water W' contains air in the air. When the diaphragm booster pump 10 is started, the pressure of the high-pressure water W' is lower than the elastic force of the compression spring 80 due to the inclusion of the air containing air A, but the air A contained in the high-pressure water W' can still be pushed through the activity. The gap between the legs 93 of the bottom 91 of the block 90 directly enters the hollow exhaust chamber 54 and enters the air flow passage 62 along the gap 92 between the springs of the compression springs 80 along the top 92 of the movable push block 90. Finally, the air A is discharged out of the outer cover 60 through the vent hole 61 (as indicated by the direction indicated by the dotted arrows in the fifteenth figure), so that the exhaust gas still has the effect in this condition, and does not The occurrence of air A cannot be discharged from the vent 56 of the bottom surface 53 of the vent 52 of the body 50. ; Thus, if the inclusions contain air A high pressure water W 'of the present invention regardless of the output from the booster pump diaphragm 10, which can achieve the functionality of the complete evacuation.

Further, as shown in FIG. 16 to FIG. 20, wherein the planar bottom portion 901 of the movable push block 900 is further recessed inwardly into a plurality of grooves 903 arranged to intersect each other so that it is placed in the hollow exhaust. After the bottom surface 55 of the chamber 54 is formed, it can still form a non-closely contact state with the vent 56 of the body 51 of the body 50; therefore, when the high pressure water W' contains air A, the air A can pass through The gaps of the groove bottom depth of the plurality of grooves 903 directly enter the hollow exhaust chamber 54 and enter the air flow passage 62 along the gap 902 between the springs of the compression springs 80 along the top 902 of the movable push block 900. Finally, the air A is discharged out of the outer cover 60 through the vent hole 61 (as shown in FIG. 19), so that it still has the function of exhausting; after all the air A is discharged out of the outer cover 60, Since the pressure of the high pressure water W' is again greater than the elastic force of the compression spring 80, the conical surface top 902 of the movable push block 900 is again pushed completely into the air flow passage 62 of the outer cover 60, and the air flow passage is again made. The entire inlet of 62 forms a state of being completely in close contact and returns to normal pressurized drainage. State (as shown in FIG twenty).

Further, as shown in the twenty-first embodiment, the outer peripheral surface of the two end tubes of the body 50 is further provided with a plurality of continuously parallel inclined flanges 57, and the outermost diameter of the inclined flange 57 The dimension is approximately equal to the inner diameter of the tubes of the outlet pipes 5a and 5b, so that when the outlet pipes 5a and 5b are placed on the bevel flanges 25, they can be more closely connected to each other and achieve the effect of not falling off at all.

Further, as shown in the twenty-second and twenty-third figures, wherein the venting holes 601 of the outer cover 600 are disposed at an angle of 90 degrees to each other with the air flow passage 602 and penetrate each other, so that the high-pressure water W 'The air contained in the inclusions can be changed to another angle when the cover 600 is discharged (as shown in Figure 23), and the air A and its entrained moisture can be prevented from directly impacting. Other components inside the portable pressure sprayer.

As shown in the twenty-fourth to twenty-fifthth embodiments, the movable push block 910 is further formed by integrally injection of a hard plastic material, and the plug is additionally inserted into the circular groove 63 of the outer cover 60. A sealing ring 70 made of an elastic rubber material is disposed, and the inner diameter of the sealing ring 70 is larger than the outer diameter of the compression spring 80, and the outer diameter dimension thereof is slightly larger than the inner diameter of the circular groove 63. When it is inserted into the circular groove 63 of the outer cover 60, an interference fit can be formed without falling off; when the high-pressure water W' contains air A, the air A can be The gap between the legs 913 of the bottom portion 911 of the movable push block 910 directly enters the hollow exhaust chamber 54, and penetrates the gap between the springs of the compression springs 80 along the top 912 of the movable push block 910 to enter the air flow passage. 62, finally, the air A is discharged out of the outer cover 60 through the vent hole 61 (as shown in the twenty-fifth figure), so it also has the effect of exhausting; all the air A is discharged out of the outer cover After 60, since the pressure of the high pressure water W' is again greater than the elastic force of the compression spring 80, the circle of the movable push block 910 The top portion 912 is pushed against the sealing ring 70 and forces a completely intimate relationship therebetween, thereby preventing the high pressure water W' from entering the air flow passage 62, thus returning to the normal pressurized drainage. Status (as shown in Figure 26).

As shown in the twenty-seventh to twenty-ninth embodiments, the inner center of the outer cover 610 is sequentially formed from a top surface to a bottom surface, and is sequentially formed into an exhaust hole 611, an air flow passage 612, and a hollow exhaust chamber 613, and the outer peripheral surface of the lower half thereof is provided with a male thread 614, wherein the exhaust hole 611 and the air flow passage 612 penetrate each other, and the air flow passage 612 and the hollow exhaust chamber 613 Interspersed with each other, and the inner diameter of the hollow exhaust chamber 613 is larger than the inner diameter of the air flow passage 62, and can be placed by the movable push block 90, and the inner diameter of the air flow passage 62 is larger than the diameter of the exhaust hole 61. In the aperture dimension, the central top of the exhaust seat 512 of the body 510 faces downward to form a concave circular groove 513, and the groove wall surface is provided with a female thread 514 for the outer peripheral surface of the lower half of the outer cover seat 610. The male thread 614 is screwed together. The exhausting operation mode is as shown in the twenty-eighth and twenty-ninth figures. When the high-pressure water W' contains air A, the air A can pass through the legs 93 of the bottom 91 of the movable push block 90. The gaps directly enter the hollow exhaust chamber 613 of the outer cover 610, and penetrate the gap between the springs of the compression springs 80 along the top 92 of the movable push block 90 to enter the air flow passage 612, and finally pass The venting hole 611 discharges the air A out of the outer cover 610 (as shown in the twenty-eighth figure), so it still has the effect of exhausting; after all the air A is discharged out of the outer cover 610, due to the high pressure water The pressure of W' is again greater than the spring force of the compression spring 80, so that the conical surface top 92 of the movable push block 90 is again pushed completely into the air flow passage 612 of the outer cover seat 610, and again makes the entire air flow passage 612 The inlet forms a state of being fully intimate and returns to the state of normal pressurized drainage (as shown in Figure 29).
