[0029] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Example 1: Please refer to Figures 1-10 This utility model provides a technical solution: a sealing structure for degassing water in a treatment head. The sealing structure for degassing water in a treatment head includes: a treatment head body 2, which is disposed on a main housing 1. A lower outer frame 4 for water storage is disposed inside the treatment head body 2. A lower inner frame 9 for water storage is disposed inside the lower outer frame 4. A ring slot 12 is provided on the surface of the lower inner frame 9. A snap-fit ​​groove 10 is provided on the inner side of the ring slot 12. A sealing pad 11 is disposed in the snap-fit ​​groove 10.

[0031] The upper water storage frame 3 has a ring insert plate 14 at its bottom. A snap-fit ​​block 16 is provided between the ring insert plate 14 and the upper water storage frame 3. A recessed area 8 is provided on the surface of the upper water storage frame 3. Liquid sealant body 17 is filled in the recessed area 8 and the ring slot 12. The ring insert plate 14 can be inserted into the ring slot 12. Several snap-fit ​​grooves 10 are provided. Several snap-fit ​​grooves are evenly distributed on the surface of the lower inner frame 9 of the water storage frame.

[0032] In use, first fill an appropriate amount of degassed water into the inner frame 9 of the water storage compartment, then fill the ring slot 12 with liquid sealant body 17 until the top of the liquid sealant body 17 and the bottom of the snap-fit ​​groove 10 are at the same height. Then, move the upper frame 3 of the water storage compartment, insert the ring insert plate 14 into the ring slot 12 and insert the snap-fit ​​block 16 into the snap-fit ​​groove 10, and press continuously. At this time, the liquid sealant body 17 inside the ring slot 12 will be squeezed into the snap-fit ​​groove 10 and the bearing area 13, so as to achieve a sealed connection between the upper frame 3 of the water storage compartment and the inner frame 9 of the water storage compartment.

[0033] Subsequently, combined Figure 3 At this time, the height of the sunken area 8 is lower than the top of the lower outer frame 4 and the upper frame 3 of the water storage. By filling the sunken area 8 with liquid sealant body 17, the upper frame 3 and the lower outer frame 4 of the water storage are sealed together, thereby achieving a double-layer sealing connection, improving the sealing performance of the internal degassed water and preventing leakage.

[0034] Example 2: Based on Example 1, both the outer frame 4 and the inner frame 9 of the water storage are circular in cross-section. The height of the outer frame 4 of the water storage is higher than that of the inner frame 9 of the water storage. The inner frame 9 of the water storage is provided with a bearing area 13, which is located between the ring slot 12 and the outer frame 4 of the water storage.

[0035] In use, the bearing area 13 can create a space between the outer perimeter of the upper water storage frame 3 and the lower water storage frame 4, which facilitates the filling of the bearing area 13 when the liquid sealant body 17 overflows from the ring slot 12, thus achieving the sealing of the connection.

[0036] The sealing gasket 11 is L-shaped and is fixedly connected to the inner wall of the insertion groove. Several snap-fit ​​blocks 16 are evenly distributed on the upper water storage frame 3. The snap-fit ​​blocks 16 can be inserted into the snap-fit ​​groove 10 and abut against the sealing gasket 11. The bottom of the bearing area 13 and the snap-fit ​​groove 10 are at the same height. The outer diameter of the upper water storage frame 3 is the same as the cross-sectional diameter of the ring plate 14. The top of the upper water storage frame 3 and the lower water storage frame 4 are at the same height. The height of the recessed area 8 is lower than that of the lower water storage frame 4.

[0037] When in use, when the snap-fit ​​block 16 is inserted into the snap-fit ​​groove 10, it will squeeze and press the sealing gasket 11, which can provide a certain buffer and improve the sealing performance at the connection between the lower inner frame 9 and the upper frame 3. The reserved recessed area 8 is convenient for filling and bearing the liquid sealant body 17, so that a seal is formed between the upper frame 3 and the lower outer frame 4.

[0038] Example 3: Based on Example 2, a first mounting hole 7 is provided on the surface of the water storage lower outer frame 4, a top ring 6 is provided on the sunken area 8, a second mounting hole 15 is provided on the surface of the top ring 6, and bolts 5 are provided in the first mounting hole 7 and the second mounting hole 15. The top ring 6 can cover the sunken area 8 and the water storage lower outer frame 4.

[0039] In use, after filling both sides of the liquid sealant body 17 and continuing until the liquid sealant body 17 solidifies, align the first mounting hole 7 and the second mounting hole 15, and install the mounting bolts 5 to connect the top ring 6 and the water storage lower outer frame 4. The top ring 6 will cover the sunken area 8, thereby covering the solidified liquid sealant body 17 inside the sunken area 8, preventing damage from external objects and improving the stability of the solidified liquid sealant body 17.

[0040] In actual use, first, fill the inner frame 9 of the water storage compartment with an appropriate amount of degassed water. Then, fill the ring slot 12 with liquid sealant body 17 until the top of the liquid sealant body 17 and the bottom of the snap-fit ​​groove 10 are at the same height. Then, move the upper frame 3 of the water storage compartment, insert the corresponding ring insert plate 14 into the ring slot 12 and insert the corresponding snap-fit ​​block 16 into the snap-fit ​​groove 10, and press continuously. At this time, the liquid sealant body 17 located inside the ring slot 12 will be squeezed into the snap-fit ​​groove 10 and the bearing area 13, realizing the sealed connection between the upper frame 3 of the water storage compartment and the inner frame 9 of the water storage compartment. Then, combine Figure 3 At this time, the height of the sunken area 8 is lower than the top of the lower outer frame 4 and the upper frame 3 of the water storage. By filling the sunken area 8 with liquid sealant body 17, the upper frame 3 and the lower outer frame 4 of the water storage are sealed together, thereby achieving a double-layer sealing connection, improving the sealing performance of the internal degassed water and preventing leakage. After filling both sides of the liquid sealant body 17, until the liquid sealant body 17 solidifies, the first mounting hole 7 and the second mounting hole 15 are aligned, and the mounting bolts 5 are installed so that the top ring 6 and the lower outer frame 4 of the water storage are connected. The top ring 6 will cover the sunken area 8, thereby covering the solidified liquid sealant body 17 inside the sunken area 8, preventing damage from external objects and improving the stability of the solidified liquid sealant body 17.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
