[0037] See also Figures 1 to 5 , this embodiment provides a garden drip irrigation device. The garden drip irrigation device can be used for drip irrigation of garden plants, watering and fertilizing trees, and especially for watering newly transplanted trees to prevent the trees from dehydrating and drying up. In this embodiment, the drip irrigation head 1 in the garden drip irrigation device is improved, and the capillary water outlet holes in the drip irrigation head 1 for water outlet are cancelled, and instead, a water-absorbing cotton swab 13 is used to control the water outlet, so that the drip irrigation head 1 is not easy to be blocked, and is convenient for daily use and maintenance. Since the water-absorbing cotton swab 13 is used for water outlet in this embodiment, there is no need to set a filter sheet in the shell 11, and the water outlet hole will not be blocked, thereby simplifying the structure of the drip irrigation head and solving the problem of water outlet blockage of the drip irrigation head.

[0038] like Figure 1 As shown, it is a schematic diagram of the structure of a garden drip irrigation device. The garden drip irrigation device includes a liquid storage barrel 2, a fertilizer adjustment barrel 3 and a drip irrigation pipe 4, and a plurality of drip irrigation heads 1 are arranged at intervals along the length direction on the drip irrigation pipe 4. The liquid storage barrel 2 stores water for drip irrigation, and a water outlet is arranged at the bottom of the liquid storage barrel 2. A water pump 23, i.e., a high-pressure pump, is arranged at the water outlet. The water outlet end of the water pump 23 is connected to the drip irrigation pipe 4 through a pipeline. The liquid flowing out of the liquid storage barrel 2 is pumped to the drip irrigation pipe 4 after being pressurized by the water pump 23, and then the drip irrigation heads 1 on the drip irrigation pipe 4 drip irrigate the trees. The fertilizer adjustment barrel 3 is connected to the liquid storage barrel 2 through the water pump 2 31. The fertilizer adjustment barrel 3 is used to dissolve the fertilizer required for the growth of the trees into a fertilizing liquid, and then pumped to the liquid storage barrel 2 through the water pump 2 31, and mixed and diluted with water in the liquid storage barrel 2, and finally drip irrigated through the drip irrigation pipe 4. An aeration pipe 22 is provided at the bottom of the liquid storage barrel 2, and the aeration pipe 22 is connected to an aeration fan 21. The aeration fan 21 is connected to the aeration pipe 22 through a pipeline, and a plurality of aeration holes are evenly arranged on the aeration pipe 22. The aeration fan 21 pumps air into the aeration pipe 22, so that the liquid in the liquid storage barrel 2 is fully in contact with the air, thereby increasing the oxygen content of the liquid.

[0039] like Figure 2 and Figure 3As shown, in this embodiment, the drip irrigation head 1 includes a shell 11 and a water-absorbing cotton swab 13; a decompression chamber 16 is provided at one end of the shell 11, and the decompression chamber 16 is connected to the drip irrigation pipe through a channel 15; one end of the water-absorbing cotton swab 13 extends into the decompression chamber 16 and the other end extends to the outside of the shell 11, which is used to absorb the water in the decompression chamber 16 to the outside of the shell 11; a water regulating ring 121 is provided around the outer periphery of the middle section of the water-absorbing cotton swab 13, and an adjusting knob 12 is provided on the outer periphery of the water regulating ring 121, and the adjusting knob 12 is threadedly connected to the shell 11 and the inner wall is against the water regulating ring 121, which is used to adjust the locking force of the water regulating ring 121 to apply pressure to the water-absorbing cotton swab 13.

[0040] The shell 11 can be made of plastic such as PP and PVC. The decompression chamber 16 is connected to the drip irrigation tube 4 through the channel 15. The diameter of the channel 15 is small (usually within 1-2 mm), and the volume of the decompression chamber 16 is large. Therefore, the pressure of the liquid in the drip irrigation tube 4 decreases after entering the decompression chamber 16 through the channel 15, thereby achieving a decompression effect. The decompression chamber 16 is provided with a water outlet channel, and the absorbent cotton swab 13 is provided in the water outlet channel, and one end of the absorbent cotton swab 13 extends into the decompression chamber 16 along the water outlet channel, and the other end of the absorbent cotton swab 13 extends to the outside of the shell. Figure 2 As shown, a conical connector 14 is provided at one end of the channel 15 away from the housing 11. The channel 15 is provided inside the connector 14, and the drip irrigation head 1 is connected to the drip irrigation pipe 4 through the connector 14, so that the channel 15 is connected to the drip irrigation pipe 4.

[0041] In this embodiment, the absorbent cotton swab can be a fluffy strip made of plant cotton, sponge, hemp or other fiber materials with water absorption characteristics. The diameter of the absorbent cotton swab 13 is equivalent to the inner diameter of the water outlet channel, and the absorbent cotton swab 13 fills the space of the water outlet channel. Therefore, the water in the decompression chamber mainly enters the external soil through the absorbent cotton swab, and very little water can flow out directly through the water outlet channel, and a good water control effect is achieved through the absorbent cotton swab.

[0042] The water regulating ring 121 is arranged on the water passage, and a thread is arranged on the inner side of one end of the regulating knob 12 close to the housing 11, and is threadedly connected to the housing 11 through the thread. The water regulating ring 121 includes a plurality of compression plates 122 arranged at intervals around the water-absorbing cotton swab 13; the inner wall of the regulating knob 12 is a conical slope and abuts against the compression plates. The water regulating ring 121 can also be made of plastics such as PP and PVC. When the regulating knob 12 is screwed in relative to the housing 11, the inner wall of the regulating knob 12 presses the water regulating ring 121 inward, so that the water regulating ring 121 shrinks inward and the radial space of the water outlet channel is reduced, thereby compressing the water-absorbing cotton swab 13 and reducing the water absorption, so that the water outlet speed of the drip irrigation head 1 is reduced; on the contrary, when the regulating knob 12 is screwed out relative to the housing 11, the compression plates 122 are stretched outward due to elasticity, and the water outlet speed of the drip irrigation head 1 is increased.

[0043] like Figure 2 As shown, in order to facilitate the rotation of the adjusting knob 12 , the outer surface of the adjusting knob 12 is provided with anti-slip textures.

[0044] In the above embodiment, the pressure reduction is mainly achieved by the resistance of the channel 15 and the volume change of the channel 15 and the pressure reduction chamber. Figure 4 As shown, in another embodiment, in order to better control the pressure in the decompression chamber, a water stop bead 17 is further provided in the decompression chamber 16. The water stop bead 17 is opposite to the channel 15 and is connected to a spring 171. The spring 171 applies pressure to the water stop bead 17 so that the water stop bead 17 blocks the channel 15.

[0045] The diameter of the water stop bead 17 is slightly larger than the inner diameter of the channel 15, so it can achieve the function of water stopping. The water stop bead 17 is pressed against the end of the channel 15 under the elastic force of the spring 171. The elastic force of the spring 171 can offset the water pressure in the channel 15. The water in the channel 15 enters the decompression chamber through the gap between the channel and the water stop bead, so the pressure of the water entering the decompression chamber can be significantly weakened. Figure 4 As shown, in order to facilitate the installation of the spring 171, a connecting plate facing the channel 15 is provided in the decompression chamber 16, one end of the spring 171 is connected to the connecting plate, and the other end is connected to the water stop bead 17. The connecting plate can be made of the same material as the housing 11.

[0046] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
