Description of the Invention: [Technical Field of the Invention] The present invention relates to a "water H structure improvement" in which a gear chamber and a control room using a movable seat are separated by upper and lower partitions. A water-reducing space is provided to allow the water conduit to communicate with the control room only to block the flow of the sediment from the flow directly into the gear chamber, so that the filtered water space penetrated into the gear chamber is filtered and the coarse impurities in the water are filtered. In order to make the gear set not only slid and cool, but also prevent the sediment from being inside the gear chamber, so that the operation of the wheel set can reach the temperature difference between the wheel chamber and the control room and the water pressure. Up to the best use. [Prior Art] According to the general common gardening sprinklers (such as US7422162, deleted 5 and US7255291), the water flow is mostly directly from the water source end into the sprinkler and then sprayed out through the water outlet. Under long-term use, impurities such as silt in the water will enter the sprinkler directly with the water flow without any filtration, so that each gear of the wheel transmission is prone to jam due to silt accumulation. The phenomenon is not smooth, which in turn reduces the service life. In addition, the water condensers of US5052621, DE3833984 and EP0362559B2 isolate the gear chamber from the water distribution system. However, when the gears are running and lacking lubrication and cooling of the water flow, each gear is prone to temperature difference due to mutual friction. It is easy to be damaged, resulting in a temperature difference between the gear chamber and the control room and a phenomenon in which the water pressure is concentrated in the control room, so that the temperature difference between the gears and the water waste cannot be balanced, and at the same time, due to the pinion (44, please refer to US5052621, 3 1353888 DE3833984 and EP0362559B2) are exposed to the outside of the gear chamber and the fixed blade ends (65, please refer to US5052621, DE3833984 and EP0362559B2) to cause interlocking, resulting in the pinion (44) and fixed blade end (65) not fully protected by the gear The interior of the chamber is susceptible to external forces and affects the operation of the gear set. Moreover, since the pinion (44) and the fixed blade end (65) are exposed on the outside of the gear, once the water flow is controlled by the control room When infiltrating into the gear chamber, the water flow will be caused by the leakage of the pinion (44) and the fixed blade end (65), causing the loss of water leakage. US5052621, DE3833984 and EP0362559B2 is completely isolated from the gear chamber sure the water distribution system in order to prevent leakage of flow phenomena, and thus can not be lubricated and the cooling water flow. The present inventors have continually tested the process methods and products in the spirit of creation, in the spirit of creation, and in the creation of methods and installation methods. Through numerous experiments and years of experience, the present invention has been improved. The present invention has been further proposed. SUMMARY OF THE INVENTION The main object of the present invention is to provide an improved sprinkler structure in which a gear chamber and a control room of a movable seat are separated by upper and lower partitions to define a water filtering space for the water conduit. It only communicates with the control room to block the flow of water and entrain the sediment directly into the gear chamber, so that the water-permeable space in the control room can seep into the gear chamber and filter the coarse impurities in the water to protect the gears. Lubrication and cooling of the water flow, not tolerant of the inability of the silt to accumulate, thus ensuring smooth operation of the gear set and balancing the temperature difference and water pressure between the gear chamber and the control room, thereby achieving a better temperature difference balance and Pressure balance. 4 1353888 .* . * The secondary object of the present invention is to provide an improved structure of a sprinkler which is completely assembled in the gear chamber of the movable seat and can be fixed with the driving gear and the water guiding pipe of the impeller The design of the meshing mechanism allows the gear set to be surely interfered with by any external force, while the water flow from the gear to the inside is not oozing out to achieve optimum use.

A hole (316) and a second water outlet (324, 324') for the setting lever (41) are located at the bottom end and the top end of the control room (33), and the two water outlets (324, 324') are Opposite to the swinging member (42) and being pushed by the lever (41) to shield one of the water outlet holes (324) from opening the other water outlet hole (324') to the upper partition plate (322) The upper side of the upper side of the control room (33) is provided with a semi-circular grooved area (325) communicating with the gear chamber (34), and a pivot hole (326) and a grooved area are provided at the center of the outer side of the sealing box (32) ( 325) and The wheel chamber (34) communicates with the driving gear (61) and the front end gear (51) of the gear set (50), and the pivot hole (326) is located on the top surface of the movable seat (30) and is peripherally disposed. a water collecting area (3〇2) for the impeller (60) is in communication with the two water outlet holes (324, 324'), and the pivot hole (326) is sleeved with a water blocking member (62) located at the impeller (60) and The water collecting area (3〇2) is blocked from the gear chamber (34) between the driving gears (61), and the first water guiding channel (327) and the second water guiding channel are disposed on one side of the water collecting area (302) ( 327') respectively communicate with the two outlet holes (324, 324,) to allow the water flow to flow from one of the outlet holes (324, or 324) to the first or first water conduit (327 or 327) to the catchment (302) The inner impeller (60) and the driving gear (61) are synchronously rotated, thereby driving the gear set (5〇) and the movable seat (30) to rotate the fixed gear segment (ill) to the lever (41) and the limit position.

Wherein, the width of the guiding groove (323) is slightly larger than the guiding rib (313) to form a narrow slit, and the depth of the guiding groove (323) is larger than the height of the guiding rib (313) to form a larger passage, so that the water flow The impurities can pass through the guide groove (323) and the guide rib (313) of the water filtering space (35), and the narrower slits flow into the wider passage and then enter the gear chamber (34) by the narrower slit. The purpose of the channel filtration is to prevent the entry of impurities into the gear chamber (34). In summary, when the invention is industrially usable and progressive, and the invention is not found in any publication, it is also novel, and when it complies with the provisions of Articles 21 and 22 of the Patent Law, Proposing an invention patent application 9 8 1353888 ·♦ » · * η 4 '· Please ask your reviewer to pay for the patent as a prayer.
