[0069] In the second embodiment, for the water spraying mechanism 2, the water in the water spraying mechanism 2 is prone to breed bacteria in the standby state after completing the water spraying operation. In order to solve the problem of bacteria breeding in the water spraying mechanism 2, the water spraying mechanism 2 is improved and designed as follows.

[0070] As Figures 7-9 shown, the embodiment provides a heating mechanism 1, comprising:

[0071] A water spraying seat 21, which is in a strip structure, is provided with a water supply channel 211 and a plurality of water outlet channels 212, and the end of the water spraying seat 21 is provided with a mounting socket 213 communicating with the water supply channel 211, and a plurality of water spraying holes 214 are further provided on the front side of the water spraying seat 21, which communicate with the corresponding water outlet channels 212, and the plurality of water outlet channels 212 respectively communicate with the water supply channel 211;

[0072] A connecting pipe 22 is provided with a plurality of connecting holes 221 on the pipe wall, and the connecting pipe 22 is sealingly inserted into the mounting socket 213 and extends into the water supply channel 211, and the connecting holes 221 communicate with the corresponding water outlet channels 212;

[0073] A second ultraviolet LED lamp 23 is arranged at the end of the connecting pipe 22 and is configured to irradiate ultraviolet light towards the connecting pipe 22.

[0074] Specifically, the connecting pipe 22 is inserted into the water supply channel 211 of the water spraying seat 21, which can be used to transport water, and after the water in the connecting pipe 22 is transported into the water spraying seat 21, the water in the connecting pipe 22 flows into the corresponding water outlet channel 212 through the connecting hole 221 to meet the requirement of water outlet.

[0077] Preferably, the connecting pipe 22 can be a quartz pipe, and the outer wall of the quartz pipe is further provided with a light reflecting layer, which is configured to reflect ultraviolet light towards the connecting hole 221.

[0079] Further, the connecting pipe 22 is provided with a positioning portion 222, and the water spraying seat 21 is provided with a positioning matching portion; the positioning portion 222 and the positioning matching portion are connected together.

[0080] Specifically, since the connecting hole 221 arranged on the connecting pipe 22 needs to be communicated with the corresponding water outlet channel 212, the connecting pipe 22 needs to be adjusted to align the connecting hole 221 with the water outlet channel 212 after being inserted into the water inlet channel.

[0083] Specifically, the water output from the water spraying hole 214 can be treated by the spray head 25 to achieve a spraying effect. The specific structure of the spray head 25 can adopt the structure of a conventional spray head, which is not limited and described here.

[0084] Further, the second ultraviolet LED lamp 23 can be installed at any end of the connecting pipe 22. For example, the second ultraviolet LED lamp 23 is arranged outside the water spraying seat 21, and the second ultraviolet LED lamp 23 is located outside the outer pipe opening of the connecting pipe 22.

[0086] Based on the water spraying mechanism 2 in the above embodiment, the dry and wet paper machine provided by the application directly or indirectly connects the water spraying mechanism 2 and the water pump 3 to realize sterilization water spraying.

[0087] By arranging the connecting pipe 22 in the water supply flow channel 211 of the water spraying seat 21, the connecting pipe 22 is used to meet the requirement of supplying water to the water spraying hole 214, and the end of the connecting pipe 22 is further provided with the second ultraviolet LED lamp 23. The second ultraviolet LED lamp 23 is arranged to irradiate ultraviolet rays into the connecting pipe 22. In actual use, the water in the connecting pipe 22 is irradiated by the ultraviolet rays generated by the second ultraviolet LED lamp 23, so that the generation of bacteria can be reduced, and the safety and experience of users are improved.
