Abstract

A drip irrigation head assembly comprises an outer sleeve member and a flow retarding member. The flow retarding member is passed through an entrance of the outer sleeve member to insert in and assemble to the plug connector of the outer sleeve member. The flow retarding member comprises a main body which is formed with a windingly-arranged threaded part and a spiral channel. One end of the main body of the flow retarding member adjacent to the entrance of the outer sleeve member is provided with a plurality of notches which are communicated with the spiral channel. The plug connector of the outer sleeve member can be inserted into a water pipe, so that water in the water pipe can pass through the notches to enter the spiral channel and then flow out of the outer sleeve member for a drip irrigation operation. The notches can be utilized to block impurities from entering the spiral channel and reduce channel blockage. Besides, the spiral channel can be utilized to extend the flow path, thereby slowing down the flow velocity of water. Further, the flow retarding member can be dissembled from or assembled to the outer sleeve member, so that the flow retarding member can be easily dissembled for cleanness. Accordingly, the replacement costs can be reduced and the usability can be promoted.

Description

Drip head assembly

The present invention is a drip irrigation head assembly, and more particularly a drip irrigation head assembly that is inserted into a pipeline to slow the flow rate and flow rate of the water.

In areas with insufficient water supply, the plants will be cast with drip irrigation equipment, so that the water flow can be effectively poured. The flow rate of each water outlet is the same, so that each plant gets the same amount of water at the same time, so the water flow needs to be slowed down. Without spraying, the water output of the drip irrigation equipment can be well controlled. As shown in Fig. 8, in order to slow down the pouring speed and pouring amount of water, the drip irrigation equipment is a drip irrigation head 90 for inserting on the water pipe 80, and the drip irrigation head The 90 includes a connector 91, a body 92, and a base 93. The block 92 is disposed between the base 93 and the connector 91. The connector 91 is fixed to the base 93, and The connector 91 is inserted into the water pipe 80. The base 93 is exposed to the water pipe. As shown in FIG. 9, the opposite sides of the block 92 form a curved flow passage 94 and have a through hole 95 communicating with both sides. The curved flow path 94 is as shown in FIGS. 8 and 9, whereby the water in the water pipe 80 is introduced between the base 93 and the block 92 via the connector 91, and the water droplets are dropped by the base 93. Among them, the water passes through the curved flow path 94 on one side of the block 92, and then enters the block 92 through the through hole 95. The curved flow passage 94 on one side is dripped from the base 93, and the water is decelerated by the flow blocking action of the double curved flow passage 94 of the block 92, so that the flow control can be achieved.

However, after the drip irrigation head 90 is used for a period of time, impurities and accumulated scale in the water may cause clogging of the curved flow passage 94, and the connector 91 and the base 93 are not detachable, and the block 92 cannot be taken out separately, and it is necessary to The drip irrigation head 90 is completely replaced, which causes a problem of high replacement cost.

In the above, the outer sleeve of the drip head assembly can be inserted into the water pipe, the base is located on the outer side of the water pipe, and the plug joint extends into the water pipe, and the water flowing in the water pipe passes through the gap of the slow flow member and flows into the spiral flow. And passing through the passage of the outer sleeve and flowing out of the outlet, wherein the slow flow member is inserted into the outer sleeve, and the notches are provided to block impurities from entering the spiral flow passage, reducing flow passage blockage, and the slowing The flow piece provides a spiral flow path, which can extend the flow distance of the water in the drip head assembly, and can slow down the flow rate, achieve the purpose of controlling the water volume and make good use of the drip irrigation of water resources, and when the flow path of the drip head assembly is blocked, The drip head assembly can be pulled out from the inserted water pipe, the slow flow piece can be easily removed from the outer set, and the slow flow piece can be disassembled and cleaned, the slow flow piece can be reused, and the drip head assembly is not Need to be replaced to reduce replacement costs.

Referring to FIG. 1 to FIG. 3, a preferred embodiment of the drip irrigation head assembly of the present invention includes an outer sleeve 10 and a slow flow member 20.

The outer sleeve 10 includes a base 11 having a laterally extending plug connector 12 on one side thereof, and a laterally extending sleeve connector 13 on the other side of the base 11 The outer side surface of the plug connector 12 is provided with a plurality of hook portions 14 arranged at intervals, and the outer side surface of the sleeve joint 13 is provided with a convex ring 15 and A passage 16 is formed in the outer sleeve 10, and an inlet 17 is formed at the end of the plug connector 12, and an outlet 18 is formed at the end of the sleeve joint 13. The outer side of the plug connector 12 is provided with a connection to the base. The tapered portion 19 of 11.

The slow-moving member 20 is inserted into the plug connector 12 of the outer sleeve 10 through the inlet 17 of the plug connector 12, and the slow-moving member 20 includes a body 21 on which a threaded portion is disposed. 22, and a spiral flow path 23 is formed, and the body 21 is provided with a plurality of notches 24 at one end adjacent to the inlet 17, and the notches 24 communicate with the flow path 23, wherein the diameter of the notch 24 is smaller than that of the flow path 23. For the caliber, as shown in FIG. 7, the slow flow member 20 is provided with a puncture portion 25 at one end adjacent to the inlet 17.

Referring to FIG. 4, the drip head assembly can be inserted into the existing water pipe 30. The plug connector 12 of the outer sleeve 10 extends into the water pipe 30, and the base 11 of the outer sleeve 10 abuts the water pipe 30. a side surface, and the tapered portion 19 of the outer side of the plug connector 12 is pressed against the rigid PVC water pipe 30, and the hook portion 14 provided on the outer side of the plug connector 12 prevents the outer sleeve 10 from slipping out of the water pipe 30, wherein the water pipe 30 is inside The water enters the plug joint 12 of the outer sleeve 10 through the notch 24 of the slow flow member 20 at the inlet 17, and the water moves along the spiral flow passage 23 provided by the slow flow member 20, thereby flowing out of the outer sleeve 10. The outlet 18, due to the notch 24 of the slow flow member 20 and the spiral flow passage 23, controls the amount of water flowing through the drip head assembly and the flow rate to achieve a drip irrigation effect.

In order to position the slow flow member 20 in the outer sleeve 10, a tapered hollow portion may be formed in the outer sleeve 10, the diameter of the inlet 17 being larger than the diameter of the outlet 18; the end of the slow flow member 20 A positioning flange may be disposed, the outer diameter of the positioning flange being larger than the diameter of the inlet 17; as shown in FIG. 8, the outer sleeve 10 is formed with a stepped hollow portion, and the inner side surface of the outer sleeve 10 forms an abutting surface 111, the slow flow member 20 extends into the outer sleeve 10 and abuts against the abutting surface 111. When the water passes through the slow flow member 20, the slow flow member 20 is positioned without moving out of the outlet 18.

As shown in FIG. 7, the damper portion 20 can directly penetrate the thin tube wall of the water tube 30, thereby improving the convenience of inserting the water tube 30, and shortening the working time of the water tube 30.
