[0029] This utility model proposes a reagent spray nozzle for air purification, such as... Figures 1 to 3As shown, it includes an end 1 and a cylinder 2 connected to the end 1. The end 1 has a flow channel 12 inside, and nozzles 11 are distributed on the upper wall of the end 1. The nozzles 11 are connected to the flow channel 12 inside the end 1. A disc 3 is provided at the inlet of the flow channel 12. Two filters 31 are distributed on the disc 3. The two filters 31 correspond to the discharge chamber 22 and the liquid flow channel 21, respectively.

[0030] The interior of the cylinder 2 is provided with a liquid flow channel 21 and a drain channel, both of which are connected to the drainage channel 12.

[0031] like Figures 1 to 3 As shown, further details are as follows:

[0032] A quick connector 4 is provided at the bottom of the cylinder 2, and the quick connector 4 is connected to the liquid flow channel 21. A plug 222 for sealing is coupled at the outlet.

[0033] In this design, quick connector 4 is a sleeve with threads on the outside, which can be used to connect to the outer pipe.

[0034] The cylinder 2 has an external drain port, which is connected to the drain chamber 22.

[0035] like Figure 3 and Figure 4 As shown, further details are as follows:

[0036] The liquid flow channel 21 and the discharge chamber 22 are separated by a partition plate 23. A first connecting ring 24 is provided at the top of the cylinder 2, and the first connecting ring 24 is connected to the liquid flow channel 21 and the discharge chamber 22. A second connecting ring 13 is provided at the bottom of the end 1, and the second connecting ring 13 is connected to the drainage channel 12. The first connecting ring 24 and the second connecting ring 13 are movably and sealingly connected.

[0037] like Figure 2 As shown, further details are as follows:

[0038] The outer side of the cylinder 2 is provided with an annular step 25, and the bottom of the end 1 is symmetrically provided with hooks 14, the curved part of the hooks 14 being below the annular step 25.

[0039] like Figure 5 and Figure 6 As shown, further details are as follows:

[0040] The upper end face of the cylinder 2 is symmetrically provided with a hook groove 26, and the lower end face of the end 1 is provided with a hook body 15 that can be coupled with the hook groove 26.

[0041] like Figure 5 and Figure 6 As shown, going a step further:

[0042] The reagent nozzle also includes a ring body 5, which is disposed on the lower end face of the end head 1 and rotatably connected thereto. A spring 51 is disposed at the bottom of the ring body 5, and the two ends of the spring 51 are respectively connected to the upper end wall of the cylinder 2 and the bottom of the ring body 5.

[0043] like Figure 4 As shown, going a step further:

[0044] The bottom of the disc body 3 is provided with a rubber strip 32 that contacts the partition plate 23.

[0045] like Figure 1 As shown, going a step further:

[0046] The top of the end 1 is detachably equipped with a cover 6, which is used to block the nozzle 11.

[0047] In this embodiment, the reagent nozzle is connected to the tube of the external infusion device via the quick connector 4. The reagent liquid flows into the liquid flow channel 21 of the cylinder 2 through the external tube, and then the reagent liquid flows into the drainage channel 12 along the liquid flow channel 21. The reagent liquid that enters the drainage channel 12 is sprayed out through the nozzle 11 of the end 1.

[0048] When the filter screen 31 corresponding to the liquid flow channel 21 becomes clogged, the water flow from the nozzle 11 can be clearly felt to decrease. At this time, the end head 1 can be pressed down to overcome the preload of the spring 51, and the end head 1 can be rotated at a certain angle so that the hook 15 at the bottom of the end head 1 stops hooking with the hook groove 26 at the top of the cylinder 2. Then, the end head 1 can be lifted up to disengage from the hook groove 26. Then, the end head 1 can be rotated half a turn to replace the filter screen 31 above the liquid flow channel 21 and above the drain chamber 22. After the replacement is completed, the end head 1 can be pressed down to make the hook 15 enter the corresponding hook groove 26. The end head 1 can be rotated at a certain angle so that the hook 15 at the bottom of the end head 1 can hook with the hook groove 26 at the top of the cylinder 2 again. At this time, the rubber strip 32 at the bottom of the disc 3 is in sealed contact with the top of the partition plate 23, preventing the liquid from flowing directly from the gap between the disc 3 and the partition plate 23.

[0049] After replacement, the filter screen 31 at the outlet of the liquid flow channel 21 is a clear filter screen 31;

[0050] Next, you can continue to use the nozzle to spray reagents as needed, or clean the clogged filter 31. The process of cleaning the clogged filter 31 is described in detail here. The nozzle 11 is blocked by fastening the cover 6, and then the plug 222 is pulled out to connect the drain chamber 22 with the outside through the drain port. Then, liquid is delivered into the liquid flow channel 21. The liquid delivered can be clean water. The liquid then flows into the drainage channel 12 along the liquid flow channel 21. Since the nozzle 11 is blocked, the liquid entering the drainage channel 12 will flow into the drain chamber 22 and pass through the clogged filter 31. The clogged filter 31 is flushed by backwashing.
