The outer wall of the guide rod is slidably connected with a sliding block. The outer wall of the sliding block is fixedly installed with one end of a cross bar. The other end of the cross bar is fixedly installed with a connecting column. The other end of the connecting column is fixedly installed with a water blocking plug. A spring is arranged on the outer wall of the guide rod. The top of the upper housing is fixedly installed with a buzzer and a warning light respectively. The inner wall of the lower housing is fixedly installed with a contact sensor. The inner wall of the upper housing is fixedly installed with an upper diaphragm. The inner wall of the lower housing is fixedly installed with a lower diaphragm.
[0006] As a preferred technical scheme of the utility model, the lower housing and the upper housing have the same size, and extension blocks are arranged on the outer walls of the lower housing and the upper housing. The extension blocks of the lower housing and the upper housing are connected by bolts.
[0007] As a preferred technical scheme of the utility model, the buzzer and the warning light are electrically connected to the contact sensor, and the detection head of the contact sensor is located on the inner wall of the lower housing.
[0008] As a preferred technical scheme of the utility model, the upper diaphragm and the lower diaphragm respectively seal the inner walls of the upper housing and the lower housing, and the fixing part of the upper diaphragm and the lower diaphragm is at the same height as the outermost end of the inner walls of the upper housing and the lower housing.
[0009] As a preferred technical solution of the present utility model, an expansion layer is provided in the middle section of the inner wall of the fixed shell, and the diameter of the expansion layer is larger than the diameter of the water blocking plug.
[0010] As a preferred technical solution of the present utility model, there are two guide rods, springs and sliding blocks, and the two guide rods, springs and sliding blocks are symmetrically arranged on both sides of the inner wall of the fixed shell, and the two sliding blocks are connected to both ends of the cross bar.
[0011] Compared with the prior art, the present utility model has the following beneficial effects:
[0012] 1. For the drip irrigation belt with anti-backflow function, by opening the water source, the water source discharges water into the interior of the fixed shell and presses the water blocking plug, so that the water blocking plug enters the expansion layer in the middle section of the fixed shell, and the water reaches the inner wall of the drip irrigation belt main body through the expansion layer. After closing the water source, the internal water pressure is unbalanced. At this time, the water inside the drip irrigation belt main body will squeeze towards the water source. At this time, the water inside the drip irrigation belt main body and the fixed shell will be blocked by the water blocking plug, so that the water inside the drip irrigation belt main body and the fixed shell cannot pass through the water blocking plug to cause backflow.
[0013] 2. For the drip irrigation belt with anti-backflow function, when the flange at the connection leaks, the leaked water will reach above the lower diaphragm. By pressing the middle part of the lower diaphragm downward with water, the bottom of the lower diaphragm is in contact with the top of the contact sensor. When the bottom of the lower diaphragm is in contact with the top of the contact sensor, the contact sensor sends a signal to the buzzer and the warning light, so that the buzzer and the warning light are activated to warn the user of the leakage here.

[0021] Please refer to Figure 1 - Figure 5 , a drip irrigation tape with an anti-backflow function, which includes a drip irrigation tape main body 1. An upper housing 3 and a lower housing 4 are respectively movably sleeved on the outer wall of the drip irrigation tape main body 1. A fixing shell 2 is fixedly installed at one end of the drip irrigation tape main body 1 away from the upper housing 3. A guide rod 5 is fixedly installed on the inner wall of the fixing shell 2. A sliding block 7 is slidably connected to the outer wall of the guide rod 5. A cross bar 8 is fixedly installed on the outer wall of the sliding block 7. One end of a connecting column 9 is fixedly installed on the outer wall of the cross bar 8, and a water blocking plug 10 is fixedly installed at the other end of the connecting column 9. A spring 6 is arranged on the outer wall of the guide rod 5. A buzzer 11 and a warning lamp 12 are respectively fixedly installed on the top of the upper housing 3. A contact sensor 13 is fixedly installed on the inner wall of the lower housing 4. An upper diaphragm 14 is fixedly installed on the inner wall of the upper housing 3. A lower diaphragm 15 is fixedly installed on the inner wall of the lower housing 4. In the above structure, the number of the drip irrigation tape main body 1 and the fixing shell 2 is several, and flange plates are provided at both the end of the drip irrigation tape main body 1 away from the fixing shell 2 and the end of the fixing shell 2 away from the drip irrigation tape main body 1. By connecting and fixing the flange plates of the rear fixing shell 2 and the front drip irrigation tape main body 1, the equipment is extended.
[0022] In a preferred embodiment, the lower housing 4 and the upper housing 3 have the same size, and extension blocks are provided on the outer walls of the lower housing 4 and the upper housing 3. The extension blocks of the lower housing 4 and the upper housing 3 are connected by bolts. In the above structure, by sleeving the lower housing 4 and the upper housing 3 at the flange connection of the two devices, the lower housing 4 and the upper housing 3 are fixed on the outer wall of the drip irrigation tape main body 1 by the bolts on the outer walls of the lower housing 4 and the upper housing 3.
[0023] In a preferred embodiment, the buzzer 11 and the warning lamp 12 are electrically connected to the contact sensor 13, and the detection head of the contact sensor 13 is located on the inner wall of the lower housing 4. In the above structure, when the detection head of the contact sensor 13 detects an object above, a signal is sent to the buzzer 11 and the warning lamp 12, causing the buzzer 11 and the warning lamp 12 to start.
[0024] In a preferred embodiment, the upper diaphragm 14 and the lower diaphragm 15 respectively seal the inner walls of the upper housing 3 and the lower housing 4, and the fixing position of the upper diaphragm 14 and the lower diaphragm 15 is at the same height as the outermost end of the inner walls of the upper housing 3 and the lower housing 4. In the above structure, when the upper housing 3 and the lower housing 4 are fitted together, the upper diaphragm 14 and the lower diaphragm 15 inside them are also in a fitted state.
[0025] In a preferred embodiment, an expansion layer is provided in the middle section of the inner wall of the fixed housing 2, and the diameter of this expansion layer is larger than the diameter of the water blocking plug 10. In the above structure, when the water blocking plug 10 reaches the expansion layer in the middle section of the inner wall of the fixed housing 2, there is no adherend around the water blocking plug 10, so that the water flow can continue to move through the water blocking plug 10.
[0026] In a preferred embodiment, the number of the guide rods 5, the springs 6 and the sliding blocks 7 is two, and the two guide rods 5, the springs 6 and the sliding blocks 7 are symmetrically arranged on both sides of the inner wall of the fixed housing 2. The two sliding blocks 7 are connected to both ends of the cross bar 8. In the above structure, the cross bar 8 is limited by the two sliding blocks 7, so that the cross bar 8 cannot rotate, and further the connecting column 9 cannot rotate, so that the movement track of the water blocking plug 10 remains straight.
[0027] Working principle: When using this device, connect the water source to the fixed housing 2 and let water pass through it, so that the water flow squeezes the water blocking plug 10 towards the direction of the connecting column 9 by pressure, so that the water blocking plug 10 drives the connecting column 9, the cross bar 8 and the sliding block 7 to squeeze towards the direction of the spring 6, causing the spring 6 to contract. When the water blocking plug 10 enters the expansion layer in the middle end of the inner wall of the fixed housing 2, the water is discharged into the inside of the fixed housing 2 from around the water blocking plug 10, passes through the fixed housing 2 and reaches the inside of the drip irrigation belt main body 1. Through the drip irrigation device and the drip holes provided inside the drip irrigation belt main body 1, the water is dripped out from the inner wall of the drip irrigation belt main body 1. When the water source stops supplying water, due to the water pressure inside the drip irrigation belt main body 1, the water inside the drip irrigation belt main body 1 moves towards the fixed housing 2. At this time, the water is blocked by the water blocking plug 10 on the inner wall of the drip irrigation belt main body 1 to prevent the water inside the drip irrigation belt main body 1 from flowing back. When there is a water leak at the connection flange between the drip irrigation belt main body 1 and the fixed housing 2, the leaked water will be discharged between the upper diaphragm 14 and the lower diaphragm 15. Due to the weight of the water, the center at the bottom of the lower diaphragm 15 will move downward, and finally touch the top of the contact sensor 13, triggering the contact sensor 13. The contact sensor 13 sends signals to the buzzer 11 and the warning light 12, causing the buzzer 11 to sound and the warning light 12 to flash, warning the user that the connection flange is loose. The user removes the bolts connecting the upper housing 3 and the lower housing 4, removes the upper housing 3 and the lower housing 4, fixes the connection flange, pours out the water inside the upper diaphragm 14, and then resets the upper housing 3 and the lower housing 4.
[0028] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
