[0002] A wet electronic chemical defoaming device is a specialized device for removing air bubbles or foam from wet electronic chemicals (such as cleaning solutions, chemical reagents, surface treatment liquids, etc.). Because wet electronic chemicals are widely used in industries such as semiconductors, liquid crystal displays, and photovoltaics, the presence of foam can affect process stability and even lead to defects. Therefore, specialized equipment has been developed to remove these air bubbles.

[0003] During the handling and transportation of electronic chemicals, bubbles are often generated due to stirring, heating, or the introduction of air bubbles. If these bubbles are not removed in time, they may affect the cleaning effect of the product, the chemical reaction process, or cause production defects. However, existing defoaming equipment suffers from problems such as difficulty in disassembly and maintenance, and inconvenient connection, resulting in low equipment maintenance efficiency. Therefore, a wet electronic chemical defoaming device is proposed to solve the above problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2 , Figure 4This utility model provides an embodiment of a defoaming device for wet electronic chemicals, comprising a base plate 1, with support frames 2 fixedly connected to both sides of the upper part of the base plate 1, a defoaming chamber 3 fixedly connected to the upper part of the support frames 2, connection ports 4 fixedly connected to both sides of the exterior of the defoaming chamber 3, a connecting pipe 24 fixedly connected to the bottom side of the interior of the defoaming chamber 3, a mounting ring 23 fixedly connected to the lower end of the connecting pipe 24, a mounting sleeve 16 fixedly connected to the bottom of the mounting ring 23, and an exhaust pipe 14 engaged inside the mounting sleeve 16. Both sides of the outer surface are fixedly connected to a fixing component, which is used to install and fix the air extraction pipe 14. One end of the air extraction pipe 14 is fixedly connected to an air pump 13. The fixing component includes an elastic block 15, which is fixedly connected to both sides of the outer surface of the air extraction pipe 14. The inner side of the mounting sleeve 16 has grooves 17 on both the front and back, and the inner side of the mounting sleeve 16 has arc-shaped inclined grooves 18 on both the front and back. The elastic block 15 is slidably connected inside the grooves 17 and the arc-shaped inclined grooves 18. The air pump 13 is fixedly connected to the upper front side of the base plate 1.

[0031] Support members 19 are fixedly connected to both sides of the outer side of the mounting sleeve 16. A connecting rod 20 is slidably connected inside the support member 19. A pull block 21 is fixedly connected to one end of the connecting rod 20. A return spring 22 is sleeved on the outer side of the connecting rod 20. One end of the return spring 22 is fixedly connected to one side of the pull block 21, and the other end of the return spring 22 is fixedly connected to the outer side of the support member 19. A conduit 6 is snapped into the inside of the connecting port 4. A filter membrane frame 5 is fixedly connected to the corresponding end of the conduit 6. The filter membrane frame 5 is set inside the defoaming chamber 3. The conduit 6 is snapped into the inside of the sealing ring 1 7 and the sealing ring 2 9.

[0032] Electronic chemicals are transported through connection port 4 and conduit 6 into the filter membrane holder 5. Then, the vacuum pump 13 is activated, drawing air from the degassing chamber 3 via the vacuum pipe 14 and connecting pipe 24, creating a vacuum. Under this negative pressure, air in the electronic chemicals passes through the degassing membrane outside the filter membrane holder 5, thus removing air bubbles. For maintenance, the pull block 21 is pressed, moving the connecting rod 20 and simultaneously squeezing the return spring 22, generating a rebound force that compresses the elastic block 15. As the elastic block 15 is compressed, the vacuum pipe 14 rotates, moving the elastic block 15 into the groove 17. Then, the vacuum pipe 14 is pulled downwards, allowing the elastic block 15 to slide out of the groove 17, completing the disassembly of the vacuum pipe 14. This facilitates the removal of air bubbles from electronic chemicals and the convenient disassembly and installation of the vacuum pipe 14, reducing the difficulty of internal pipeline maintenance and improving work efficiency.

[0033] Reference Figure 1 , Figure 2 , Figure 3 A sealing ring 7 is engaged with one side of the inside of the connector 4. A spring ring 8 is provided inside the sealing ring 7. Four connecting sleeves 11 are engaged with one side of the inside of the sealing ring 7. Each connecting sleeve 11 has an insertion hole 12 inside. An insert 10 is engaged with the inside of the insertion hole 12. A sealing ring 9 is fixedly connected to one end of the insert 10. The sealing ring 9 is engaged with the other side of the inside of the connector 4.

[0034] The sealing rings 7 and 9 installed inside the connection port 4 ensure the airtightness of the conduit 6 during the transportation of electronic chemicals to the external pipeline. The spring ring 8 inside the sealing ring 7 tightens the sealing ring 7, making it fit tightly against the outside of the conduit 6. The insert 10 is inserted into the socket 12, fixing it to the connecting sleeve 11, which in turn connects the sealing ring 9 to the sealing ring 7. Under the action of the sealing ring 9, the airtightness between the conduit 6 and the external pipeline is further ensured, achieving a double guarantee of the sealing effect between the conduit 6 and the external pipeline, improving the airtightness during the transportation of electronic chemicals, and reducing the possibility of leakage during water transportation.

[0035] Working principle: When the device is needed, electronic chemicals are transported through the connection port 4 and the conduit 6 into the filter membrane holder 5. Then, the vacuum pump 13 is started, which, under the action of the vacuum pipe 14 and the connecting pipe 24, evacuates the air in the degassing chamber 3, creating a vacuum inside. Under the negative pressure, the air in the electronic chemicals passes through the degassing membrane outside the filter membrane holder 5, thereby removing the bubbles in the electronic chemicals. When maintenance is required, the pull block 21 is pressed, which moves the connecting rod 20 and simultaneously squeezes the return spring 22. While the elastic block 15 is being squeezed, the vacuum pipe 14 is rotated and moved into the groove 17. Then, the vacuum pipe 14 is pulled down to complete the disassembly of the vacuum pipe 14. This achieves the removal of bubbles in electronic chemicals and the convenient disassembly and installation of the vacuum pipe 14, reducing the difficulty of internal pipeline maintenance and improving work efficiency.

[0036] The sealing ring 7 installed inside the connection port 4 is tightened by the spring ring 8 inside the sealing ring 7. The spring ring 8 is then inserted into the socket 12 via the plug 10, which engages with the connecting sleeve 11. This allows the sealing ring 9 to be installed and connected to the sealing ring 7. With the double sealing of the sealing ring 7 and the sealing ring 9, the sealing performance between the conduit 6 and the connection port 4 is ensured. This provides double protection for the sealing effect between the conduit 6 and the connection port 4, improves the sealing performance of the external pipeline when transporting electronic chemicals, and reduces the possibility of leakage during water transportation.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
