[0036] Embodiment two: Figures 1-10As shown, the two sides of the moisturizing shell 201 are provided with mounting areas, and the inside of each mounting area is fixedly connected with a self-checking assembly 3. Each self-checking assembly 3 comprises an observation glass window 301 for observing the moisture change in the inside of the moisturizing shell 201, and each observation glass window 301 is transparent. The inside bottom surface of each mounting area is fixedly connected with a first limiting net 303, and the inside top surface of each mounting area is fixedly connected with a second limiting net 304. The inside of each mounting area is placed with a test paper 302 for detecting the moisture content in the inside of the moisturizing shell 201, and each test paper 302 is a cobalt chloride test paper.

[0037] In use, the self-checking assembly 3 can detect the moisture content in the air in the covered area of the moisturizing shell 201. The specific installation steps are as follows: first, the observation glass window 301 is fixed on the inner wall of the mounting area. The observation glass window 301 is transparent, so that the user can directly observe the color change of the test paper 302 behind the observation glass window 301. In addition, the observation glass window 301 is water-proof, so the moisture in the inside of the moisturizing shell 201 will not be released from the observation glass window 301.

As the water vapor in the moisturizing shell 201 decreases, the environment gradually becomes dry, and the color of the cobalt oxide test paper gradually changes from purple red to blue. Because the cobalt oxide test paper is very sensitive to the moisture content in the environment, when the water vapor in the inside of the moisturizing shell 201 increases, the test paper 302 absorbs moisture and the color changes to purple red. When the water vapor decreases and the environment in the inside of the moisturizing shell 201 becomes dry, the test paper 302 loses moisture and the color returns to blue. Therefore, the moisture content of the environment in the inside of the moisturizing shell 201 can be determined by the color change of the test paper 302.

The moisturizing sponge 502 is made of special moisturizing cotton for inkjet heads of printers. When the moisturizing shell 201 is installed, the moisturizing sponge 502 can absorb water, and has good moisturizing effect and can continuously provide a humid environment for the ink ejection port of the inkjet head body 101. When the high-speed inkjet printer is used again, the cleaning function of the printer can clean the ink ejection port more thoroughly. In addition, the cotton fiber column 402 is made of natural fiber and can expand and elongate when absorbing water. When the moisturizing shell 201 is first installed, each cotton fiber column 402 is in an expanded and elongated state after absorbing water. At this time, the elastic force of the pushing spring 404 is not enough to push the reinforcing plate 403. However, the water in the moisturizing shell 201 will evaporate after a long time, and the water contained in the moisturizing sponge 502 and the cotton fiber column 402 will decrease. The cotton fiber column 402 will shrink and shorten when the water evaporates, and the pushing spring 404 will push the reinforcing plate 403 forward, so that the pushing spring 404 is folded. When the reinforcing plate 403 moves, the fixed rod 406 fixed on the surface of the reinforcing plate 403 will drive the needle 407 to move. The liquid bag 503 is pierced by the needle 407, and the liquid in the liquid bag 503 flows out, so that the moisturizing sponge 502 can absorb water again. When the moisturizing sponge 502 is not replenished in time, the ink ejection port can be moisturized. By turning the inkjet head body 101 on which the moisturizing shell 201 is installed, the water in the liquid bag 503 flows out and is absorbed by the cotton fiber column 402. The cotton fiber column 402 absorbs water and expands and elongates again, so that the fixed rod 406 starts to return to the original position, and the reverse hook 408 pierces the outer skin of the liquid bag 503 in the opposite direction, so that the water in the liquid bag 503 flows out.
