As shown in fig. 1 to 9, the drip irrigation pipe 1 includes a water pipe 101 and a plurality of drip irrigation connectors 102, and the drip irrigation connectors 102 include: the water dripping device comprises a connecting pipeline 11, an elastic baffle 12 and a water dripping head 13, wherein at least one mounting hole 111 is formed in the connecting pipeline 11; the elastic baffle 12 is arranged in the connecting pipeline 11 and seals and covers the mounting hole 111, and a through hole (not marked) is formed in the part, opposite to the mounting hole 111, of the elastic baffle 12; the water dropping head 13 is inserted into the mounting hole 111 and connected with the elastic baffle 12, a water inlet cavity 131 communicated with the through hole is formed in the water dropping head 13, and a water outlet 132 communicated with the water inlet cavity 131 is formed on the side wall of the water dropping head 13; wherein the elastic baffle 12 deforms toward the mounting hole 111 under the action of the water pressure in the connecting pipe 11 and pushes the water drop head 13 to protrude from the mounting hole 111 so that the water outlet 132 is exposed from the mounting hole 111, and the connecting pipe 11 is connected to the water pipe 101.
Specifically, the connecting pipe 11 in the drip irrigation connector of this embodiment is used for conveying water, the water flow direction is shown by the arrow in fig. 1, and in the actual use process, when the drip irrigation connector is in a state of not supplying water, referring to fig. 1 and 2, the elastic baffle 12 is in an original posture, at this time, the drip head 13 is located in the mounting hole 111, and the hole wall of the mounting hole 111 will shield the water outlet 132, so that sediment and plant roots can be prevented from blocking the water outlet 132. In the water supply state, water enters the connecting pipeline 11, the water pressure in the connecting pipeline 11 is gradually increased, referring to fig. 3 and 4, along with the increase of the water pressure in the connecting pipeline 11, the elastic baffle 12 deforms into the mounting hole 111 under the action of the water pressure, and the water drop head 13 is located in the mounting hole 111 and connected to the elastic baffle 12, after the elastic baffle 12 protrudes into the mounting hole 111, the water drop head 13 is driven to move towards the outer side of the mounting hole 111, and along with the continuous increase of the water pressure of the water supply in the connecting pipeline 11, the water outlet 132 is finally partially or completely exposed from the mounting hole 111, and at this time, the water can be output through the water outlet 132 to realize the drip irrigation operation. After the drip irrigation operation is completed, the water pressure in the connecting pipeline 11 gradually drops, in the process, the elastic baffle 12 is reset by self elasticity, and simultaneously drives the drip head 13 to retract into the mounting hole 111, and in the retracting process of the drip head 13, the water outlet 132 always keeps a water outlet state, so that sediment is prevented from adhering to the water outlet 132 in the water return process, and when the water outlet enters the mounting hole 111, the water outlet 132 is further shielded and protected by the wall of the mounting hole 111. The distance between the drip head 13 and the hole wall of the mounting hole 111 is set according to the requirement, and on the premise of ensuring that the drip head 13 can stretch smoothly, the hole wall of the mounting hole 111 is required to ensure effective anti-blocking protection for the water outlet 132, and the specific distance range value can be adaptively set according to specific use situations, for example: the distance is smaller when used in a clay environment, and the distance can be larger when used in a sand environment, and the specific distance range is not limited. In addition, in order to increase the deformation amount of the elastic baffle 12, the mounting hole 111 is a stepped hole or a trumpet-shaped hole, the inner hole diameter of the mounting hole 111 is larger than the outer hole diameter of the mounting hole 111, specifically, taking a stepped hole as an example, the hole size of the mounting hole 111 close to the outer pipe wall of the connecting pipe 11 is smaller than the hole size of the mounting hole 111 close to the inner pipe wall of the connecting pipe 11, and the part of the drip head 13 with the water outlet 132 is located in the outer hole body.
In addition, the wall of the connecting pipe 11 is provided with the mounting hole 111, which corresponds to the mounting hole 111, and the connecting pipe 11 may be made of a harder material, for example, a PVC pipe or the like, so as to ensure that the mounting hole 111 has enough structural strength and cannot be deformed, and meanwhile, the wall thickness of the connecting pipe 11 needs to meet the requirement of the actual field application environment by shielding the water outlet 132 with the wall of the mounting hole 111 in the retraction state of the water drop head 13, and the specific wall thickness and the opening size of the mounting hole 111 are not limited herein. As shown in fig. 8, for the arrangement mode of the mounting hole 111, a sealing cover 112 may be further disposed at a pipe orifice of the connecting pipe 11, the mounting hole 111 is disposed on the sealing cover 112, and the elastic baffle 12 is correspondingly mounted on the inner surface of the sealing cover 112, and the specific mounting mode is not described in detail. As for the manner in which the connection pipe 11 is connected to the water pipe 101, as shown in fig. 9, a plurality of water pipes 101 may be employed, and then the connection pipe 11 is disposed between two adjacent water pipes 101; alternatively, as shown in fig. 10, a continuous water pipe 101 is adopted, a mounting port (not shown) is provided on the pipe wall of the water pipe 101, and the corresponding pipe orifice of the connecting pipe 11 is hermetically connected to the mounting port.
The elastic baffle 12 may be made of elastic rubber or silica gel, and the edge of the elastic baffle 12 may be fixed on the wall of the connecting pipe 11 by gluing or thermal welding, for example: the elastic baffle 12 may be connected to the pipe wall of the connecting pipe 11 by means of hot melt welding or laser welding, without limitation; the drip head 13 may be of unitary construction with the elastomeric barrier 12 or alternatively, the drip head 13 may be attached to the elastomeric barrier 12 by gluing or heat welding. The structure of the water outlet 132 on the water drop head 13 may be a circular, bar-shaped or oval opening, and the opening may be a gradually enlarged opening along the water outlet direction, so that even if the water outlet 132 is blocked by sediment, the sediment in the water outlet 132 is quickly discharged by utilizing the water pressure to match with the deformation of the water drop head 13 when water is supplied next time, so as to improve the anti-blocking capability.
Further, in order to more effectively improve the anti-blocking performance, the drip head 13 further includes: the first sealing ring 133 is distributed around the periphery of the drip head 13 and is positioned outside the water outlet 132. Specifically, after the water dripping head 13 is retracted into the mounting hole 111, the first sealing ring 133 seals the outside of the water outlet 132, so that the outside silt is more effectively prevented from entering the water outlet, and various sealing modes for the first sealing ring 133 exist, for example: as shown in fig. 1 and 2, the first sealing ring 133 is provided on the sidewall of the drip head 13, and after the drip head 13 is retracted into the mounting hole 111, the first sealing ring 133 is also positioned in the mounting hole 111, and the edge of the first sealing ring 133 is abutted against the wall of the mounting hole 111; alternatively, as shown in fig. 5 and 6, the first sealing ring 133 is provided at the outer end portion of the drip head 13, and when the drip head 13 is retracted into the mounting hole 111, the first sealing ring 133 is located outside the connection pipe 11 with the edge of the first sealing ring 133 abutting against the outer pipe wall of the connection pipe 11, and the first sealing ring 133 will cover the gap between the drip head 13 and the mounting hole 111 on the outside. Preferably, the drip head 13 is further provided with a second sealing ring 134 around its periphery, the second sealing ring 134 is located at the inner side of the water outlet 132, so that the water outlet 132 is located between the first sealing ring 133 and the second sealing ring 134, and the edge of the second sealing ring 134 will be always abutted against the wall of the mounting hole 111, so that, in the process of water supply and drip irrigation, as the drip head 13 gradually extends out of the mounting hole 111, the second sealing ring 134 also moves in the mounting hole 111, and even if sediment enters between the mounting hole 111 and the drip head 13, the moving second sealing ring 134 can push out the sediment outwards and discharge the sediment along with the water output by the water outlet 132 during water supply and drip irrigation again, thereby further improving the anti-blocking performance.
Further, in order to reduce the blockage of the drip head 13 from the inside due to the impurities contained in the water flowing in the connecting pipe 11, the water inlet member 14 is further included, a plurality of water inlet channels 1400 are formed in the water inlet member 14, and the water inlet direction of the water inlet channels 1400 is inclined and reversely arranged with the water flow direction in the connecting pipe 11; wherein, the water inlet component 14 is arranged in the through hole, the water inlet channel 1400 is communicated with the water inlet cavity 131, and the water in the connecting pipeline 11 enters the water inlet cavity 131 through the water inlet channel 1400.

Specifically, the water inlet member 14 is assembled by the chassis 141 and the plug 142, the chassis 141 and the plug 142 may be an integral structure, or may be assembled by a split design, the plug 142 is inserted into the through hole, the chassis 141 is used as a fixing member and connected to the elastic baffle 12, the chassis 141 and the elastic baffle 12 may be connected by gluing or thermal welding, meanwhile, the water inlet member 14 may be made of hard plastic as required, and the water inlet member 14 may be made of an elastic material, such as elastic rubber or silica gel, for increasing the deformation of the elastic baffle 12. In addition, in order to avoid the water flowing from the water inlet member 14 protruding from the inner wall of the connecting pipe 11 to cause a larger flow resistance, the edge of the chassis 141 facing the water flowing direction in the connecting pipe 11 is provided with an inclined flow guiding surface 1411, and the inclined flow guiding surface 1411 can be inclined along the water flowing direction so as to effectively guide the water flowing smoothly through the inclined flow guiding surface 1411, and the edge of the elastic baffle 12 facing the water flowing direction in the connecting pipe 11 can also adopt the arrangement described above.
The water outlet quantity of the water outlet can be adjusted by controlling the water pressure of the water supply to control the extending quantity of the water drop head so as to achieve the purpose of adjusting the drip irrigation speed. In addition, through further increase water pressure, can also utilize water pressure to carry out the washing operation to the delivery port of drip head, under great water pressure effect, on the one hand the water yield of delivery port increases, and on the other hand the deflection of delivery port also increases to the purpose of clearance is realized to the delivery port that silts up.
