[0024] Embodiment

[0025] Please refer to Figures 1-4 , the present invention provides an inlaid pressure compensation drip head, including a drip irrigation tape 1, a plurality of drip irrigation holes 2 are formed in the drip irrigation tape 1, drip head bodies are fixedly arranged on the inner side wall of the drip irrigation tape 1 corresponding to the drip irrigation holes 2, each drip head body includes a housing 3 and a cover body 4 connected to the housing 3, and the cover body 4 is communicated with the drip irrigation hole 2; a pressure compensation component is arranged on the housing 3.

[0026] One end of the housing 3 is provided with a water inlet chamber 5, a total water inlet is formed at the outer end of the water inlet chamber 5, a first water outlet is formed at the inner end of the water inlet chamber, the water inlet is communicated with one end of a first labyrinth flow channel 6, the other end of the first labyrinth flow channel 6 is communicated with one end of the pressure compensation component, and the other end of the pressure compensation component is communicated with a water storage chamber 7.

[0027] The pressure compensation component includes an outer chamber 8 with both ends communicating with the first labyrinth flow channel 6 and the water storage chamber 7, and the outer chamber 8 is fixedly connected to the housing 3. An inner chamber 9 is arranged in the outer chamber 8. The inner chamber 9 is a movable chamber and is not fixedly connected to the housing 3. However, due to the connection of the elastic member and the restriction of the cover body 4, the inner chamber only moves horizontally on the surface of the housing 3. Both ends of the inner chamber 9 are connected to the outer chamber 8 through a plurality of elastic members 10. The elastic members 10 are springs or other elastic connecting members. Springs are provided to prevent the inner chamber 9 from moving excessively and fitting together with the outer chamber 8 to block the third water outlet. Water outlets two 11 are provided at both ends of the inner chamber 9 that are not connected to the outer chamber 8.

[0028] At one end of the inner chamber 9 and the outer chamber 8 close to the first labyrinth flow channel 6, a first water inlet and a second water inlet are respectively provided. The second water inlet and the first water inlet are connected through a telescopic pipe 12. The telescopic pipe 12 is adapted to the shapes of the first water inlet and the second water inlet to ensure that water flows into the inner chamber 9 and can undergo telescopic deformation as the inner chamber 9 moves. At one end of the outer chamber 8 communicating with the water storage chamber 7, a third water outlet is provided. On the water storage chamber 7, a third water inlet is provided. The third water inlet and the third water outlet are connected through a channel 13.

[0029] On the cover body, a water inlet hole 14 is provided, and the water inlet hole 14 communicates with the water storage chamber 7. The water flow in the water storage chamber 7 flows into the water storage cavity 16 through the water inlet hole 14. On the side of the cover body 4 and the housing 3 facing away from each other, a drip irrigation cavity 15 and a water storage cavity 16 are provided. The water storage cavity 16 communicates with the water inlet hole 14. A fourth water outlet is provided on the water storage cavity 16, and a fourth water inlet is provided on the drip irrigation cavity 15. The fourth water outlet and the fourth water inlet are connected through a second labyrinth flow channel 17. The second labyrinth flow channel 17 plays a role in secondary flow stabilization and uniformity. The drip irrigation cavity 15 communicates with the drip irrigation hole 2, and the water flow in the drip irrigation cavity 15 flows out through the drip irrigation hole 2 for drip irrigation.

[0030] A number of support rods 18 are provided on the housing 3, and a number of insertion slots 19 are correspondingly provided on the cover body 4. The support rods 18 and the insertion slots 19 are provided to prevent the drip head main body from deforming during ultrasonic welding.

[0031] On one side of the housing 3 and the cover body 4 where they are connected, a first sealing edge 20 and a second sealing edge 21 are respectively provided. On the second sealing edge 21 and the first sealing edge 20, a connecting edge 22 and a connecting groove 23 are respectively provided. By providing the sealing edges, the housing 3 and the cover body 4 are more closely fitted together and are more firmly connected under the connection of the connecting edge 22 and the connecting groove 23, and finally are welded together by ultrasonic welding.

[0032] During specific use, when the water flow fills the entire drip irrigation tape 1, the water flow enters the water inlet chamber 5 through the main water inlet, flows into the first labyrinth flow channel 6 through the first water outlet, and after the stable flow and uniform effect of the first labyrinth flow channel 6, it flows into the inner cavity 9 of the pressure compensation component through the first water inlet, the telescopic pipe, and the second water inlet. Due to the impact of the water flow, the inner cavity 9 will be impacted and move towards the side of the third water outlet, causing the gap between the inner cavity 9 and the outer cavity 8 to narrow on the side of the third water outlet, reducing the outflow of the water flow. The water flow in the inner cavity 9 still needs to flow out through the narrowed gap from the two second water outlets 11. As the gap decreases, the water flow rate will also decrease, thereby adjusting the water pressure. The water flow flowing into the water storage chamber 7 flows into the water storage cavity 16 through the water inlet holes 14, and then flows into the drip irrigation cavity 15 through the second labyrinth flow channel 17. After the stable flow and uniform effect of the second labyrinth flow channel 17, it flows out through the drip irrigation holes 2 for uniform drip irrigation.

[0033] Therefore, the present utility model adopts an inlaid pressure compensation drip head with the above structure. By setting the pressure compensation component, the amount of water output is adjusted, enabling a stable and uniform flow rate for drip irrigation; by setting the first labyrinth flow channel and the second labyrinth flow channel, the irrigation water pressure is reduced, improving the uniformity of irrigation.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present utility model, and these modifications or equivalent replacements do not enable the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present utility model.
