Description

Technical Field

[0001] This utility model relates to the technical field of water purification and water treatment equipment accessories, specifically to an adjustable filter head for a purification tank. Background Technology

[0002] Filter heads are core components primarily used in filter bed water distribution systems and filters. Current filter head technology lacks adjustable length; furthermore, the filter holes or slits on the filter head directly face suspended solids in the water, which easily clog the holes after a period of use, reducing the filtration capacity of the entire filter bed water distribution system or filter, thus requiring frequent maintenance and cleaning. The inconvenience of adjusting the filter head length also makes cleaning the filter holes difficult. Utility Model Content

[0003] In order to solve the technical problems and shortcomings of the prior art, the present invention provides an adjustable filter head for purification tanks, which can be adjusted in length, is simple and reliable to operate, is easy to clean, and is not prone to clogging of filter holes.

[0004] To achieve the above and other related objectives, the present invention adopts the following technical solution:

[0005] An adjustable filter head for a purification tank includes a filter head body. An adjustable long rod assembly is fixed to the lower end of the filter head body. The long rod assembly includes a female rod body and a male rod body. An internal thread is provided on the inner side of the lower end of the female rod body, and an external thread is provided on the upper end of the male rod body. The internal thread and the external thread are mutually compatible. A nut that is compatible with the external thread is provided at the end of the external thread of the male rod body.

[0006] Preferably, the length of the external thread is greater than the length of the internal thread.

[0007] Preferably, the wall thickness of the male rod and the female rod is the same, and both the internal and external threads have thread grooves, which are curved surfaces.

[0008] Preferably, a plurality of gradually opening, inclined, elongated filter holes are evenly distributed on the outer peripheral surface of the filter head body. The filter hole group includes a first punch and a second punch, and a "V"-shaped pressure groove is formed at the center line position where the first punch and the second punch are parallel.

[0009] Preferably, the bottom plate of the filter head body is provided with pressure holes, which are distributed at intervals on the circumference of different radii and are in an arc shape.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model uses an adjustable-length rod assembly to replace the traditional single rod structure, thereby realizing the adjustment of the rod length. In terms of specific structure, the mutual rotation of the mother rod and the child rod is used to achieve adjustment through a threaded structure. The nut is specially designed to be located at the end of the external thread, so that the nut can be used to limit and prevent loosening. The mother rod and the nut are both on the external thread of the child rod. When the two rotate relative to each other, they generate opposing pressure, thereby achieving reliable fastening.

[0012] 2. In order to adapt to the length adjustment requirements, the thread length needs to be matched, and the thread length requirements of the nut also need to be considered. Therefore, a larger external thread length is beneficial to the firmness of the assembly and the convenience and stability of the adjustment.

[0013] 3. The threaded groove is designed as a curved surface, which can improve the smoothness of rotation operation and further improve the stability and tightness of the operation. This threaded fit can reduce the gaps on the mating surfaces, thereby reducing the possibility of air leakage.

[0014] 4. In the design of the filter head body, the filter hole group is conducive to forming a rotating airflow and is not conducive to clogging the filter holes. In addition, there are pressure holes in the bottom plate, which is conducive to releasing excessive air pressure.

[0015] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0027] Example:

[0028] This invention discloses an adjustable filter head for a purification tank, as described in the following embodiment. Figure 1 , Figure 2 and Figure 3As shown, the device includes a filter head body 1, with an adjustable-length long rod assembly 2 fixed to its lower end. Specifically, the long rod assembly 2 includes a female rod body 21 and a male rod body 22. The lower inner side of the female rod body 21 is provided with an internal thread 211, and the upper end of the male rod body 22 is provided with an external thread 221. The internal thread 211 and the external thread 221 are mutually compatible, and a nut 23 that is compatible with the external thread 221 is provided at the end of the external thread 221 of the male rod body 22. The above structure is made of stainless steel.

[0029] Based on the above structure, the technical principle of this application is as follows: An adjustable-length rod assembly 2 replaces the traditional single-rod structure, thereby achieving rod length adjustment. Specifically, the adjustment is achieved through the mutual rotation of the mother rod 21 and the daughter rod 22, using a threaded structure. A nut 23 is specially designed to be located at the end of the external thread 221, thus enabling it to limit and prevent loosening. Both the mother rod 21 and the nut 23 are on the external thread 221 of the daughter rod 22. When they rotate relative to each other, they generate opposing pressure, thus achieving reliable fastening. Operationally, the daughter rod 22 and the mother rod 21 can be rotated relative to each other until the desired length is achieved. Then, the nut 23 is rotated so that it abuts against the mother rod 21, thus securing the rod.

[0030] In this design, the length of the external thread 221 is greater than the length of the internal thread 211. To accommodate the adjustment length requirements, the thread length needs to be adapted, and the thread length requirements of the nut 23 also need to be considered. Therefore, a larger external thread 221 is beneficial for secure assembly and convenient and stable adjustment.

[0031] In this design, to save materials, the wall thickness of the male and female rods is the same, and both the internal thread 211 and the external thread 221 have threaded grooves 24, which are curved surfaces. The curved design of the threaded grooves 24 improves the smoothness of rotational operation, further enhancing the stability and tightness of the operational fit. This threaded fit reduces gaps in the mating surfaces, thereby reducing the possibility of air leakage.

[0032] In this plan, refer to Figure 4 and Figure 5 The filter head body 1 has a plurality of gradually opening, inclined, elongated filter hole groups 3 evenly distributed on its outer peripheral surface. The filter hole group 3 includes a first punch 31 and a second punch 32. A "V" shaped pressure groove 33 is formed at the center line position where the first punch 31 and the second punch 32 are parallel.

[0033] refer to Figure 3As can be seen, pressure holes 4 are provided on the bottom plate of the filter head body 1. The pressure holes 4 are distributed at intervals on the circumference of different radii and are in an arc shape. In the design of the filter head body 1, the filter hole group 3 is conducive to forming a rotating airflow and is not conducive to clogging the filter holes. In addition, the pressure holes 4 on the bottom plate are also conducive to releasing excessive air pressure.

[0034] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
