Therefore, the second spring 606 presses the second pressing plate 602 and the sealing ring 604, the sixth water passing cavity 502 and the third water passing cavity 403 are isolated, the pressures of the two water passing cavities are not affected by each other, and the stability of the pressure of the ink outlet is ensured. When the ink in the third water passing cavity 403 gradually flows out, negative pressure is formed in the third water passing cavity 403, when the negative pressure is large enough, the first spring 605 is compressed, the first pressing plate 601 pushes the pressing rod 6021 of the second pressing plate 602 backward, the pressing rod 6021 and the sealing ring 604 are pushed open, the third water passing cavity 403 is communicated with the sixth water passing cavity 502, the sixth water passing cavity 502 is at positive pressure at the moment, the third water passing cavity 403 is at negative pressure, the ink in the sixth water passing cavity 502 flows into the third water passing cavity 403, the pressure in the third water passing cavity 403 gradually rises, the first spring 605 gradually recovers, when the elastic force of the first spring 605 is smaller than that of the second spring 606, the second pressing plate 602 presses the sealing ring again, and the sixth water passing cavity 502 is isolated from the third water passing cavity 403, and the process is repeated. Therefore, the spring forces of the first spring 605 and the second spring 606 respectively act on two sides of the water passing channel, and the pressure of the ink is added to form a dynamic balance, so that the pressure can be further adjusted, and the effect of stably supplying ink to the printing head is achieved.
