[0003] The working principle of piezoelectric ceramic valve is to control the flow of fluid by piezoelectric effect, and piezoelectric effect refers to the phenomenon that some crystals or ceramic materials will deform or displace when an external electric field is applied. The piezoelectric ceramic valve contains piezoelectric material inside, which will deform when voltage is applied. Specifically, when voltage is applied to the piezoelectric material, the positive and negative charges inside the material will rearrange, generating internal stress, which will cause the material to deform. This deformation can be transmitted to the valve through the designed mechanical structure, so as to open or close the valve.

In addition, the existing piezoelectric ceramic valve usually requires complex operation steps during installation and maintenance, which is not convenient for regular maintenance of internal components. Therefore, the utility model provides a quick-release piezoelectric ceramic valve easy to adjust the needle pressure. UTILITY MODEL CONTENTS

[0024] Please see Figures 1-4 This utility model provides a technical solution: a quick-release piezoelectric ceramic valve for easy adjustment of the striking pin pressure, including a first valve body shell 1, on which a mounting mechanism for the piezoelectric ceramic valve is provided, the mounting mechanism including:

[0025] The locking assembly includes a first valve body housing 1 with locking groove housings 3 fixed on both sides, a locking rod 301 sliding inside the locking groove housing 3, and a second valve body housing 2 fixed to the inner wall of the locking rod 301.

[0026] The adjustment assembly includes a piezoelectric ceramic 5 fixed inside the second valve body housing 2. A deformation rod 501 is provided at the lower end of the piezoelectric ceramic 5. Utilizing the driving technology of the piezoelectric ceramic 5, when the piezoelectric ceramic 5 is subjected to an external electric field, it will deform, and the deformation rod 501 will be converted into mechanical displacement. This is existing technology and will not be elaborated on further. A positioning block 6 connected to the lower end of the deformation rod 501 is provided through a push assembly. A striker body 601 is fixed at the lower end of the positioning block 6.

[0027] In a preferred embodiment, a rubber strip 101 is fixed to the inner wall edge of the first valve body shell 1, and the first valve body shell 1 is tightly fitted to the second valve body shell 2 through the rubber strip 101. A locking shell 4 is fixed to the side wall of the first valve body shell 1, and a locking block 401 is engaged inside the locking shell 4. A connecting rod 302 is fixed to the outer wall of the locking block 401, and locking blocks 303 are fixed to the upper and lower ends of the connecting rod 302. The locking blocks 303 can be vertically inserted into the slot shell 3 and the locking rod 301. The locking shell 4 and the locking block 401 are locked together by bolts. The first valve body shell 1 is tightly fitted to the second valve body shell 2 through the rubber strip 101, which improves the tightness after installation. The sealing design prevents dust from entering the valve body and damaging internal components. During installation, the second valve body housing 2 is inserted into the slotted housing 3 on both sides of the first valve body housing 1 via the locking rod 301. Then, the locking blocks 303 at both ends of the connecting rod 302 are vertically inserted into the slotted housing 3 and the locking rod 301. At the same time, the locking block 401 in the middle of the connecting rod 302 is inserted into the locking housing 4 and locked with bolts. This completes the installation of the first valve body housing 1 and the second valve body housing 2. The bolts are then loosened to remove the connecting rod 302 for disassembly of the housing. This simplifies the installation process and makes maintenance and replacement of parts simpler and faster.

[0028] In a preferred embodiment, the push assembly includes a fixed plate 7 fixed to the upper end face of the positioning block 6. An electric push rod 701 is fixed to the inner wall of the fixed plate 7. A push block 702 is fixed to the telescopic end of the electric push rod 701. A movable rod 703 is rotatably connected to the inner wall of the push block 702 via a rotating shaft. The positioning block 6 is located at the other end of the movable rod 703, and the movable rod 703 is rotatably connected to the positioning block 6 via a rotating shaft. Four sets of telescopic sleeve rods 704 are fixed to the upper end face of the positioning block 6. The upper ends of the telescopic sleeve rods 704 are fixedly connected to the deformation rod 501. A positioning groove 603 is opened on the inner wall of the second valve body shell 2. Both ends of the positioning block 6 are slidably connected to the positioning groove 603. A spring 602 is provided at the lower end of the positioning block 6, located outside the ejector pin body 601. The electric push rod 701 is used to drive the telescopic movement of the push block 702. The push block 702 drives the movement of the movable rod 703. Then, the positioning block 6... The rotating shafts at both ends of the movable rod 703 are rotatably connected to the push block 702, thereby pushing the positioning block 6 and allowing the positioning block 6 to slide along the positioning groove 603. At the same time, the positioning block 6 slides and extends through the telescopic sleeve rod 704 and the deformation rod 501, controlling the distance between the striker body 601 and the piezoelectric ceramic 5, controlling the pressure of the striker body 601, and the entire adjustment process can be automatically controlled by the electric push rod 701 without manual intervention. This can improve production efficiency, reduce errors caused by human operation, and improve product quality and consistency. The electric push rod 701 usually has a fast response speed and can quickly adjust the pressure of the striker to adapt to different working requirements. When the striker body 601 is compressed, the positioning block 6 is compressed at the bottom of the second valve body shell 2 by the spring 602, providing a buffering effect, reducing impact force, and avoiding damage caused by hard contact.

[0029] In addition, in piezoelectric ceramic valves, the piezoelectric ceramic chip is the core component of the valve. It has the piezoelectric effect. When an external electric field is applied to the piezoelectric ceramic chip, the chip will deform and generate mechanical displacement. The deformation is then converted into the motion of the striking pin, which is existing technology.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] During operation, the electric push rod 701 drives the extension and retraction of the push block 702, which in turn drives the movement of the movable rod 703. Then, the positioning block 6 is rotatably connected to the push block 702 through the rotating shafts at both ends of the movable rod 703, thereby pushing the positioning block 6 and allowing it to slide along the positioning groove 603. At the same time, the positioning block 6 slides and retracts through the telescopic sleeve rod 704 and the deformation rod 501, controlling the distance between the striker body 601 and the piezoelectric ceramic 5, controlling the pressure of the striker body 601, and the entire adjustment process can be automatically controlled by the electric push rod 701 without manual intervention. This can improve production efficiency, reduce errors caused by human operation, and improve product quality and consistency. The electric push rod 701 usually has a fast response speed and can quickly adjust the pressure of the striker to adapt to different working requirements. When the striker body 601 is compressed, the positioning block 6 is compressed at the bottom of the second valve body shell 2 by the spring 602, providing a buffering effect.

[0032] Then, during maintenance, the first valve body housing 1 is tightly fitted to the second valve body housing 2 via rubber strip 101, improving the sealing performance after installation and preventing dust from entering the valve body and damaging internal components. During installation, the second valve body housing 2 is inserted into the slot housing 3 on both sides of the first valve body housing 1 via a locking rod 301. Then, the locking blocks 303 at both ends of the connecting rod 302 are vertically inserted into the slot housing 3 and the locking rod 301. At the same time, the locking block 401 in the middle of the connecting rod 302 is inserted into the locking housing 4 and locked with bolts, thus realizing the installation of the first valve body housing 1 and the second valve body housing 2. At the same time, the bolts are loosened to remove the connecting rod 302 for disassembly of the housing, simplifying the installation process and making maintenance and replacement of parts simpler and faster.
