[0040] In order to make the above objectives, characteristics and advantages of the present application more obvious and understandable, the specific embodiments of the present application will be described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0041] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application.

[0043] Please refer to Figure 1 The water treatment device in an embodiment comprises an aeration head 1, which is used for aerating a water body. The shape of the aeration head 1 can be designed according to requirements. For example, the aeration head 1 can be circular or elliptical. Of course, the aeration head 1 can also be designed as a polygon, such as a quadrilateral or a hexagon. The aeration head 1 can be arranged in a plurality of circumferential directions around an aeration pipe, and the plurality of aeration heads 1 are connected to the same aeration pipe.

[0044] Please refer to Figure 2 In an embodiment, the aeration head 1 comprises a base 10, an aeration membrane 20, a gland 30 and a dismounting pin 40. The aeration membrane 20 is arranged between the base 10 and the gland 30, and a mortise and tenon structure is arranged between the base 10 and the aeration membrane 20 and / or between the aeration membrane 20 and the gland 30. That is, the mortise and tenon structure is designed between the base 10 and the aeration membrane 20, or between the aeration membrane 20 and the gland 30, or between the base 10 and the aeration membrane 20 and between the aeration membrane 20 and the gland 30.

[0045] In an embodiment, the gland 30 is provided with a pressing portion 31 extending towards the center of the base 10, and a mortise and tenon structure is arranged between the pressing portion 31 and the aeration membrane 20. Specifically, the aeration membrane 20 is provided with a mortise eye 50, and a tenon tongue 60 of the pressing portion 31 is inserted into the mortise eye 50, so that the pressing portion 31 and the aeration membrane 20 are connected by the mortise and tenon structure.

[0046] like Figure 3 As shown, in another embodiment, the aeration membrane 20 is provided with tenons 60, and the base 10 and / or the pressure cap 30 is provided with mortises 50. The tenons 60 on the aeration membrane 20 are inserted into the mortises 50 of the base 10 and / or the pressure cap 30. The protruding tenons 60 of the aeration membrane 20 can be compressed and deformed during assembly to function as a sealing ring, preventing gas from escaping between the base 10 and the aeration membrane 20.

[0047] Specifically, the local thickness of the aeration membrane 20 is increased to form a tenon 60. Both the base 10 and the pressure cap 30 have mortises 50, and these mortises 50 are located at the same position on the aeration membrane 20. This simplifies the structure of the aeration membrane 20 and facilitates the assembly of the aeration head 1. Alternatively, the mortises 50 on the base 10 and the pressure cap 30 can be located at different positions on the aeration membrane 20; in this case, the aeration membrane 20 can be locally thickened at the corresponding position to form the tenon 60.

[0048] Please see Figure 4 In one embodiment, the aeration membrane 20 includes a planar aeration zone 21 and an angled folded edge zone 22 connected to the edge of the aeration zone 21. The base 10 has a folded edge portion 11 corresponding to the folded edge zone 22 on its edge, and the folded edge zone 22 is pressed and fixed between the folded edge portion 11 and the pressure cap 30. The aeration membrane 20 is fixed by circumferential pressing, which avoids the installation of the aeration membrane 20 affecting the size of the aeration zone 21, resulting in more uniform air output from the pores at the center and edges of the aeration zone 21.

[0049] Based on the above embodiments, furthermore, the tenon and mortise structure between the base 10 and the aeration membrane 20 and / or between the aeration membrane 20 and the pressure cap 30 is provided within the folded edge area 22. The aeration membrane 20 is provided with a mortise 50, and a protruding tenon 60 on the pressure cap 30 is inserted into the mortise 50. For example... Figure 5 As shown, or, the base 10 has a mortise 50, and the aeration membrane 20 partially protrudes to form a tenon 60, which is inserted into the mortise 50 of the base 10. Figure 6 As shown, or, the aeration membrane 20 is provided with a mortise 50, and the protruding tenon 60 on the base 10 is inserted into the mortise 50 of the aeration membrane 20.

[0050] like Figure 5 and Figure 6As shown, the base 10 and the cover 30 are connected by a mortise and tenon structure to press and fix the aeration membrane 20 between the base 10 and the cover 30. The aeration membrane 20 is clamped between the base 10 and the cover 30 in a manner of interference fit, and the aeration membrane 20 is always in a compressed state after assembly, and the elastic deformation of the aeration membrane 20 generates pressure on the sealing surface to ensure the sealing effect.

[0051] In an embodiment, the edge of the base 10 is formed with a mounting portion 12, and the mounting portion 12 and the cover 30 are connected by a mortise and tenon structure. Specifically, the mounting portion 12 is connected with the folded edge portion 11 of the base 10, and the mortise hole 50 of the mounting portion 12 is a vertical opening, which facilitates the vertical connection of the base 10 and the cover 30. As shown in Figure 7 Further, as shown, the mounting portion 12 extends horizontally away from the center of the base 10, and the mortise hole 50 is provided in the mounting portion 12, and the tongue 60 of the cover 30 is vertically inserted into the mortise hole 50 of the mounting portion 12. When disassembling the cover 30, an upward force is applied to the bottom of the cover 30, so that the cover 30 and the base 10 can be disassembled.

[0052] As shown in Figure 8 Of course, the mounting portion 12 can also extend horizontally towards the center of the base 10, and the mounting portion 12 extends to the lower part of the base 10, and the mortise hole 50 is provided in the mounting portion 12, and the tongue 60 of the cover 30 is vertically inserted into the mortise hole 50 of the mounting portion 12. The installation of this structure is relatively difficult, but the disassembly pin 40 is a hidden design and is not easy to be damaged by external force.

[0053] As shown in Figure 9 and Figure 10 Of course, in other embodiments, the mortise and tenon relationship between the base 10 and the cover 30 can be interchanged. That is, the cover 30 is provided with a mortise hole 50, and the tongue 60 of the mounting portion 12 is vertically inserted into the mortise hole 50 of the cover 30, so that the base 10 and the cover 30 are connected by a mortise and tenon structure. At this time, since the cover 30 is blocked by the base 10, the disassembly of the cover 30 needs to open a disassembly hole 51 on the base 10, and when the cover 30 is disassembled, the tool outside the base 10 pushes the cover 30 upwards through the disassembly hole 51, so that the cover 30 and the base 10 are disassembled and separated.

[0054] Please refer to Figure 11 In an embodiment, the mortise hole 50 opened by the mounting portion 12 of the base 10 can be a closed inner hole, or a slit with an opening. Please refer to Figure 12 The cover 30 can be a non-closed ring, that is, the cover 30 has a truncated notch, or the cover 30 is divided into multiple segments 32 in the circumferential direction, and the cover 30 is composed of two or more parts, and the notch of the cover 30 or the notches of the adjacent two segments 31 are connected by a connecting piece 33. Figure 11The connecting piece 33 is provided with a mortise 50, and the tongue 60 formed on both sides of the gap of the cover 30 is inserted into the mortise 50 of the connecting piece 33, so as to realize the mortise and tenon connection between the connecting piece 33 and the cover 30. Of course, the connecting piece 33 can also be provided with the tongue 60, and the cut part of the cover 30 is provided with the mortise 50, and the two are connected.

[0055] Please refer to Figure 6 , Figure 9 and Figure 13 , the tongue 60 of the mortise and tenon structure between the base 10 and the cover 30 is provided with the mortise 50, and the dismounting pin 40 is inserted into the mortise 50, so as to limit the separation of the mortise and tenon structure between the cover 30 and the base 10, that is, the tongue 60 between the base 10 and the cover 30 is locked and fixed by the dismounting pin 40.

[0056] Specifically, when the installation part 12 is provided with the mortise 50, the tongue 60 of the cover 30 is vertically inserted into the mortise 50 of the installation part 12, and the part of the tongue 60 of the cover 30 extending out of the mortise 50 is designed as the mortise 50, and the dismounting pin 40 is inserted into the mortise 50 of the cover 30. When the cover 30 is provided with the mortise 50, the tongue 60 of the installation part 12 is vertically inserted into the mortise 50 of the cover 30, and the part of the tongue 60 of the installation part 12 extending out of the mortise 50 is designed as the mortise 50, and the dismounting pin 40 is inserted into the mortise 50 of the installation part 12.

[0057] In an embodiment, the dismounting pin 40 is fixed in the mortise 50 of the tongue 60 extending out of the base 10 or the cover 30 by friction or the clamping piece 70, and the dismounting pin 40 cannot be freely taken out, so as to avoid the disassembly of the aeration head 1 after assembly.

[0058] Please refer to Figure 14 , specifically, the dismounting pin 40 can be formed in various forms, for example, the end of the dismounting pin 40 is provided with an elastic clamp, which expands after being compressed through the mortise 50 and cannot be freely taken out. Alternatively, the surface of the dismounting pin 40 is made of a material with large resistance, such as a brush or a rubber sleeve, which cannot be freely taken out under the action of resistance after being inserted into the mortise 50. Alternatively, the end of the dismounting pin 40 is provided with the clamping piece 70, and the end of the dismounting pin 40 is provided with the clamping piece 70 after being inserted into the mortise 50, so as to realize self-locking.

[0059] In an embodiment, in addition to the fact that the aeration membrane 20 of the aeration head 1 is made of elastic rubber material, the other components of the aeration head 1 are preferentially made of materials with high strength and corrosion resistance, such as organic polymer materials ABS, UPVC, PP, etc., and can also be made of metal materials with higher strength.

[0060] The water treatment equipment and the aeration head 1 thereof split the aeration head 1 into four parts of the base 10, the aeration membrane 20, the gland 30 and the dismounting pin 40, and utilize the basic principle of mortise and tenon to design the parts into concave-convex structures that are interlocked and limited, that is, each part cannot move and rotate in three-dimensional direction, thus realizing simple and effective fixation and fundamentally solving the complicated assembly problem of the aeration head 1.

[0061] The above examples are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some or all of the technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
