[0011] Further, the air cylinder comprises an outer wall, and a piston is slidably connected to the inside of the outer wall.

[0012] By adopting the technical scheme, the sliding fit of the outer wall of the air cylinder and the piston utilizes the working principle of the air cylinder, so that gas pressurization can be achieved by simple pressing.

[0013] Further, one side of the piston is fixedly connected with a pressing rod, and one end of the pressing rod is fixedly connected with an arc-shaped handle.

[0014] By adopting the technical scheme, the pressing rod and the arc-shaped handle form a handle structure, so that the arc-shaped handle can be gripped to control the movement of the pressing rod, and even people with less strength can easily operate.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] Example 1:

[0028] An airport landscaping and greening cultivation device, such as Figures 1-5 As shown, the device includes a lower shell 1 and an upper shell 2. The lower shell 1 has an internal cavity 3. An air cylinder 4 is fixedly connected to the bottom of the lower shell 1. An air pipe 5 is fixedly connected to one end of the air cylinder 4. The air pipe 5 passes through the lower shell 1, and one end is located at the top of the cavity 3. Several water guide rods 6 are fixedly connected through the bottom of the lower shell 1. A one-way valve 7 is fixedly connected to the bottom end of the water guide rods 6. A filling port 8 passes through the top of the inner wall of the lower shell 1. The cavity 3 and the water guide rods 6 provide a reliable liquid delivery path. Pressurization is used to assist the liquid flow and reduce energy loss. A sealing cap is screwed on the filling port 8, which can be opened to add nutrient solution during filling and closed when not needed to prevent air leakage. The filling port 8 and the air pipe 5 are staggered to prevent interference.

[0029] See Figure 4 and Figure 5 The one-way valve 7 includes a ring 701, and a diaphragm flap 702 is fixedly connected to the inner wall of the ring 701, which simplifies the one-way valve assembly process. The ring 701 can be directly injection molded, reducing production costs.

[0030] See Figure 4 and Figure 5The four film petals 702 are arranged in a ring shape and uniformly distributed, and the four-petal structure realizes sealing by abutting each other when being closed, ensures the sealing performance, and significantly improves the reliability.

[0031] Referring to Figure 3 The air cylinder 4 comprises an outer wall 401, and a piston 402 is slidably connected inside the outer wall 401; the piston 402 is made of rubber and can maintain performance in long-term use, thereby reducing maintenance costs.

[0032] Referring to Figure 3 The piston 402 is fixedly connected with a pressing rod 403 at one side, and the pressing rod 403 is fixedly connected with an arc-shaped handle 404 at one end; the arc-shaped handle 404 is ergonomically designed to fit the palm curvature and cooperate with the curvature of the lower shell 1, so that the holding stability can be ensured in a wet environment under the premise of ensuring the appearance, and slipping is avoided.

[0033] Referring to Figure 2 and Figure 3 The water guide rod 6 is wrapped with a water permeable film, and the water permeable film can block the invasion of soil particles and root systems and avoid clogging the water guide holes, thereby improving the maintenance period.

[0034] The implementation principle of the utility model is as follows: first, the threaded plug of the filling opening 8 is unscrewed, liquid is injected into the bottom of the cavity 3 through the filling opening 8, a gas buffer space is reserved at the top of the cavity 3, so that the gas can be injected into the cavity 3 through the air cylinder 4, the material of the film petals 702 is plastic, and the film petals 702 are naturally closed under the action of the self-elastic force, thereby preventing liquid from exuding outside;

[0035] When it is necessary to inject liquid under pressure, the arc-shaped handle 404 of the air cylinder 4 is pressed, so that the piston 402 pushes the gas to enter the top of the cavity 3 through the air pipe 5, the gas pressure in the cavity 3 rises, the liquid surface is lowered, the liquid pressure pushes open the four film petals 702 of the one-way valve 7, and a flow channel is formed.

[0036] The liquid exudes through the water guide holes on the surface of the water guide rod 6, the water permeable film wrapped outside the water guide holes blocks the soil from clogging the water guide holes, the air cylinder handle 404 is reset, the gas pressure in the cavity 3 decreases, the film petals 702 restore the closed state under the action of the self-elastic deformation, backflow is blocked, and the liquid not discharged from the cavity 3 is ready for use under pressure next time.
