Description

Technical Field

[0001] This utility model relates to the field of filter heads, specifically to an adjustable tower-type filter head. Background Technology

[0002] The filter head is a backwashing device in the bottom water distribution system of the filter bed. It effectively flushes out sludge and debris from the filter bed, ensuring the normal operation of the water quality and quantity. Existing filter head types include mushroom-shaped, plum-shaped, tower-shaped, and cylindrical. These filter heads are generally made of ABS engineering plastic, which has high pressure resistance, does not deform in the gaps, and ensures no dead water areas between the filter plates, no sludge accumulation, and excellent performance. Filter heads are suitable for treating drinking water, as well as various industrial water applications such as beverage, printing and dyeing, and swimming pools. They can also be used in industrial wastewater and domestic sewage treatment projects.

[0003] The tower-shaped filter head, resembling a tower, possesses a unique shape that contributes to its excellent performance in filter beds. The upper part of the tower (the filter cap) is typically a structure with numerous small holes or slits. These holes and slits are used to filter water, effectively blocking suspended particles and making the water clearer after passing through the filter cap. For example, there is an existing filter head with an adjustable, easy-to-clean stem, disclosed in CN221207091U.

[0004] Currently, when filter heads are installed in filter beds, the height of traditional filter heads cannot be flexibly adjusted due to the different depths of different filter beds. This can easily lead to uneven water distribution in some filter beds, affecting the filtration effect. Furthermore, since the filter heads cannot adapt to the different design depth requirements of filter beds, it is necessary to replace them with filter heads of appropriate height and reinstall them before use, which increases both the workload and the cost. Utility Model Content

[0005] Therefore, this utility model provides an adjustable tower-type filter head. By adding a hollow tube to extend the length of the long handle, and by using a fixing component and an adjusting component, the length of the long handle extending out of the hollow tube can be easily adjusted, thereby adjusting the height of the filter cap. This allows the filter head to adapt to different filter bed design depth requirements, so that the filter cap can achieve the best filtration effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable tower-type filter head, comprising a filter cap and a long handle, wherein the filter cap is sleeved on the long handle via a filter seat, a hollow tube is sleeved on the outer side of the long handle, and a fixing component is provided on the long handle for adjusting the length of the long handle extending out of the hollow tube, the fixing component comprising sleeves respectively embedded in the inner walls of both sides of the long handle, and insert rods slidably provided inside both sleeves, one end of the insert rod passing through the sleeve and the long handle in sequence, and at least one slot is provided on the inner walls of both sides of the hollow tube, the insert rod being inserted into the slot, and an adjustment component is provided on the long handle for adjusting the position of the two insert rods.

Each pull rope has a pull rod connected to its bottom end, and one end of the pull rod passes through a sleeve and is connected to an insert rod inside the sleeve.

[0009] Furthermore, a return spring is fitted on the outer side of each of the two pull rods. The two ends of the return spring are connected to the insertion rod and the inner wall of the sleeve, respectively. The return spring generates elastic force to push the insertion rod into the slot for stable insertion.

[0010] Furthermore, the top of the long handle is provided with a groove that is adapted to the slide plate, the slide plate is slidably disposed in the groove, and the bottom of the groove is provided with two round holes that are connected to the inside of the long handle, and two pull ropes pass through the two round holes respectively.

[0011] Furthermore, the top of the skateboard has a storage slot, and a movable pull ring is connected inside the storage slot. The movable pull ring makes it easy to pull the skateboard up, making it more convenient to operate.

[0012] Furthermore, two limiting wheels are fixedly installed inside the long handle, and two pull ropes pass around the two limiting wheels respectively. The pull ropes are kept away from the sleeve under the limitation of the limiting wheels, so as to avoid friction damage between the pull ropes and the sleeve.

[0013] Furthermore, multiple slots are arranged in a linear array on the inner wall of the hollow tube, a protrusion is fixedly provided on the inner wall of the hollow tube, and a groove adapted to the protrusion is opened on the inner wall of the long handle. The protrusion is located in the groove, and a sealing ring for improving sealing is provided between the hollow tube and the long handle.

[0014] Furthermore, the filter base is threadedly connected to the long handle, and the top of the filter base has an annular groove.

By unscrewing the nut, the filter cap can be removed from the long handle, which facilitates cleaning and replacement of the filter cap.

[0015] This utility model has the following advantages:

[0016] 1. This utility model extends the length of the long handle by adding a hollow tube, and at the same time, it can easily adjust the length of the long handle extending out of the hollow tube with the help of fixing components and adjusting components. In this way, the height of the filter cap can be adjusted, so that the filter head can adapt to different filter pool design depth requirements, so that the filter cap can achieve the best filtration effect.

[0017] 2. By using a return spring in conjunction with the insertion rod, the connection between the long handle and the hollow tube can be strengthened. The height of the long handle can be quickly adjusted with the help of the slide plate, pull rope, and pull rod. At the same time, the slide plate is located at the top of the long handle, which makes the operation faster and more efficient, and can also effectively prevent contamination from contact with sewage.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Refer to the instruction manual appendix Figure 1-3 This utility model provides an adjustable tower-shaped filter head, including a filter cap 1 and a long handle 2. The filter cap 1 is sleeved on the long handle 2 through a filter seat 3. Specifically, the cross-section of the filter cap 1 is set in a tower shape, and a hollow tube 4 is sleeved on the outside of the long handle 2. A sealing ring 14 for improving the sealing performance is provided between the hollow tube 4 and the long handle 2.

[0029] The filter base 3 is threadedly connected to the long handle 2. The top of the filter base 3 is provided with an annular groove 15. The bottom end of the filter cap 1 is inserted into the annular groove 15. The top end of the long handle 2 extends out of the top of the filter cap 1, and the top end of the long handle 2 is threadedly connected with a nut 16 for fixing the filter cap 1.

[0030] When using it, first install the filter base 3 onto the long handle 2, then put the filter cap 1 onto the long handle 2 and fix it with the nut 16, then put the hollow tube 4 onto the long handle 2 and fix it, and finally install the hollow tube 4 onto the long handle 2. The filter cap 1 can block suspended particles and other impurities in the water, and the filtered water flows out through the long handle 2, thus achieving the filtration effect.

[0031] Refer to the instruction manual appendix Figure 1-6 A fixing component 5 is provided on the long handle 2 for adjusting the length of the long handle 2 extending out of the hollow tube 4. The fixing component 5 includes sleeves 501 respectively embedded in the inner walls of both sides of the long handle 2. Insert rods 502 are slidably provided inside the two sleeves 501. One end of the insert rod 502 passes through the sleeve 501 and the long handle 2 in sequence. At least one slot 503 is opened on both sides of the inner wall of the hollow tube 4. Multiple slots 503 are distributed in a linear array on the inner wall of the hollow tube 4. The insert rod 502 is inserted into the slot 503.

[0032] Next, a return spring 504 is sleeved on the outside of both pull rods 603. The two ends of the return spring 504 are respectively connected to the inner wall of the insertion rod 502 and the sleeve 501. The return spring 504 generates elastic force to push the insertion rod 502 into the slot 503 for stable insertion.

[0033] The long handle 2 is provided with an adjustment component 6 for adjusting the position of the two insert rods 502. The adjustment component 6 includes a slide plate 601. Two pull ropes 602 are fixedly provided at the bottom of the slide plate 601. Each pull rope 602 is connected to a pull rod 603 at its bottom end. One end of the pull rod 603 passes through the sleeve 501 and is connected to the insert rod 502 inside the sleeve 501.

[0034] Furthermore, a groove 7 adapted to the slide plate 601 is provided at the top of the long handle 2. The slide plate 601 is slidably disposed in the groove 7. Two round holes 8 connected to the inside of the long handle 2 are provided at the bottom of the groove 7. Two pull ropes 602 pass through the two round holes 8 respectively. A storage groove 9 is provided at the top of the slide plate 601. A movable pull ring 10 is connected in the storage groove 9, which makes it convenient for the user to pull the slide plate 601 to adjust the position of the plug rod 502.

[0035] During the use of the filter head, the movable pull ring 10 can be grasped to move the slide plate 601 upward. When the slide plate 601 moves upward, the two pull ropes 602 pull the two pull rods 603 respectively. The two pull rods 603 are pulled out of the sleeve 501, which drives the insertion rod 502 to move out of the slot 503. At this time, the return spring 504 is compressed. After pulling the long handle 2 upward and adjusting the height of the filter cap 1, the movable pull ring 10 is released. When the return spring 504 is no longer pulled, it generates elasticity and pushes the insertion rod 502 into one of the slots 503, which firmly fixes the long handle 2 and the hollow tube 4 together for continued use. This can adapt to different filter pool design depth requirements so that the filter cap 1 can achieve the best filtration effect.

[0036] In addition, to prevent wear on the pull rope 602, two limiting wheels 11 are fixed inside the long handle 2. The two pull ropes 602 pass around the two limiting wheels 11 respectively. The limiting wheels 11 limit the pull ropes 602, thereby preventing the pull ropes 602 from contacting and rubbing against the sleeve 501 and causing damage.
