[0006] The aforementioned Chinese invention patent application number 200710195188.X has fully achieved the expected effect of "exhaust" after actual mold opening and mass production. However, during the test, it was found that the air discharged from the exhaust seat of the diaphragm booster pump contained Contains a small amount of water, which will cause the interior of the portable pressure sprinkler to be invaded by moist water vapor, which will cause damage to other internal components and shorten the service life. Therefore, the present invention is aimed at exhausting The problem of moisture and water damage derived from the time, and then further propose a solution

Embodiment Construction
[0044] Such as Figure 8 and Figure 9 As shown, the water storage tank exhaust structure of the portable pressure sprinkler of the present invention is made up of an exhaust hole 22 and an exhaust pipe 50. on the bottom surface 23 of the type water storage tank 2, and is connected and fixed by one of the end nozzles 51 of the exhaust pipe 50, and the other end nozzle 52 of the exhaust pipe 50 is connected with the portable pressure sprinkler. The exhaust seat 30 of the diaphragm booster pump 10 is connected and fixed; wherein, the exhaust hole 22 extends toward the direction of the outer wall surface of the bottom surface 23 of the portable water storage tank 2 and protrudes into a hollow flange column 24, and the hollow The outer diameter of the flange column 24 is slightly smaller than the inner diameter of the exhaust pipe 50, so that one of the end nozzles 52 of the exhaust pipe 50 can be tightly looped on the outer peripheral surface of the hollow flange column 24 witho...

The invention provides an exhaust structure of a water storage tank of a portable pressure water sprayer. The exhaust structure comprises an exhaust vent and an exhaust pipe, wherein, the exhaust vent is arranged on the bottom surface of the water storage tank, one end of the exhaust pipe is fixedly connected with the exhaust vent, and the other end of the exhaust pipe is arranged on the exhaust seat of a diaphragm booster pump in the pressure water sprayer. In the invention, when air contained in booster water is exhausted via the outlet of the exhaust seat of the diaphragm booster pump, theair can enter the exhaust pipe immediately and directly pass through the exhaust vent under the guide of the exhaust pipe so that the air and moisture carried in the air can be fully discharged into the water storage tank, thus preventing internal parts of the portable pressure water sprayer from being invaded by moist aqueous vapor during the running process of the portable pressure water sprayer.
Description
【Technical field】 [0001] The invention relates to an exhaust structure of a water storage tank of a portable pressure sprinkler, which has complete protection against the air discharged during the exhaust process of the diaphragm booster pump in the portable pressure sprinkler and the water entrained in it. Blocking effect, and keep the inside of the whole portable pressure sprinkler dry, which can avoid the damage of the machine parts and the shortening of the service life due to the invasion of moisture and water vapor. 【Background technique】 [0002] The known portable pressure sprinklers disclosed at present, such as Chinese Patent Publication No. CN1978255A, CN101073794A, CN1899701A, Chinese Utility Model Patent No. CN2877885Y and U.S. Patent No. US5303866 etc. are all, and its mutual structure is substantially all the same, as Figure 1 to Figure 3 As shown, it is mainly composed of a water spray gun, a portable water storage tank, a set of rechargeable batteries and a ...
