Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1-Figure 3 The utility model provides a technical solution: a filter distribution head, comprising a fixed ring 2 and a distribution body 1, the distribution body 1 is in a circular ring shape; a plurality of fan-shaped cavities are provided on the distribution body 1, and the plurality of fan-shaped cavities are evenly distributed along the circumference of the axis of the distribution body 1; specifically, the distribution body 1 can use the distribution body 1 disclosed in Chinese patent CN213348042U, that is, the fan-shaped cavity partitions of the distribution body 1 in this embodiment include an exhaust zone, a blowing zone, a transition zone, a filtrate zone, a preliminary exhaust zone, and a washing zone; or the distribution head in this embodiment can also adopt other existing technologies, which will not be repeated here; in addition, an opening 24 is provided on the fixed ring 2 to match the various fan-shaped cavity partitions on the distribution body 1.

[0025] The fixing ring 2 is coaxial with the distribution body 1, and four deformable support bars 3 are arranged between the fixing ring 2 and the distribution body 1. The four deformable support bars 3 are evenly distributed along the circumference of the axis of the fixing ring 2; the deformable support bars 3 are in an arc-shaped structure, and one end of each deformable support bar 3 is fixed on the fixing ring 2, and each deformable support bar 3 is detachably arranged on the fixing ring 2.

[0026] A first annular groove 21 is coaxially provided at one end of the fixing ring 2 adjacent to the distribution body 1, and a second annular groove 23 is coaxially provided at the other end of the fixing ring 2; four through-holes 22 are provided between the first annular groove 21 and the second annular groove 23, and the four through-holes 22 are evenly distributed along the circumference of the axis of the fixing ring 2, and the four through-holes 22 correspond to the positions of the four deformable support bars 3; the through-holes 22 are in an arc-shaped structure, and the through-holes 22 are adapted to the deformable support bars 3, and each deformable support bar 3 passes through the first annular groove 21, the corresponding through-hole 22 and the second annular groove 23 in sequence, and the part of the deformable support bar 3 located inside the second annular groove 23 is connected to the fixing ring 2 by screws, thereby realizing that the deformable support bar 3 can be detachably set on the fixing ring 2.

[0027] In this embodiment, the deformable support bar 3 can be made of polyethylene material, which has good elasticity; the fixing ring 2 is used to be installed on the filter. Since the deformable support bar 3 is connected between the distribution body 1 and the fixing ring 2, the deformable support bar 3 can be elastically deformed, and the distribution body 1 and the fixing ring 2 are only in contact with each other; therefore, when the filter is working and the vibration produces an impact on the distribution body 1 in any direction in the vertical plane, the deformable support bar 3 helps to slow down the impact suffered by the distribution body 1, thereby enhancing the protective effect on the distribution body 1, and then improving the service life of the distribution body 1.

[0028] Example 2

[0029] See also Figure 4 This embodiment is based on the first embodiment, and four placement grooves 11 adapted to the deformable support strips 3 are provided at one end of the distribution body 1 adjacent to the fixed ring 2. The four placement grooves 11 are evenly distributed along the circumference of the axis of the distribution body 1, and one end of the four deformable support strips 3 is respectively fixed in the corresponding placement grooves 11; by providing the placement grooves 11, it is convenient for one end of the deformable support strip 3 to be embedded in the distribution body 1.

[0030] Example 3

[0031] See also Figure 5-Figure 7 This embodiment is based on the second embodiment. A support cylinder 5 is coaxially arranged at one end of the fixing ring 2 adjacent to the distribution body 1. The inner ring surface of the support cylinder 5 is aligned with the inner ring surface of the distribution body 1, that is, the inner ring surface diameter of the support cylinder 5 is equal to the inner ring surface diameter of the distribution body 1. A plurality of shock-absorbing components 4 are arranged between the outer ring surface of the support cylinder 5 and the inner ring surface of the distribution body 1. The support cylinder 5 and the distribution body 1 can adopt an integrally formed structure.

[0032] The shock-absorbing assembly 4 includes a support seat 41 fixedly arranged on the outer ring surface of the support cylinder 5, and an arc-shaped buffer pad 42 is arranged on the support seat 41. The arc-shaped buffer pad 42 is made of rubber or silicone; a fixed baffle 44 is fixedly arranged at one end of the support cylinder 5, and a limiting seat 43 is arranged in the arc-shaped buffer pad 42. The limiting seat 43 is adjacent to the end of the support seat 41 away from the fixed baffle 44, and the limiting seat 43 is fixed to the support seat 41 by a screw connection; specifically, the screw penetrates the arc-shaped buffer pads 42 of the limiting seat 43, and the screw thread is connected to the support seat 41.

[0033] A plurality of support balls 45 are arranged between the limit seat 43 and the fixed baffle 44. The plurality of support balls 45 are clamped on the arc-shaped buffer pad 42. The arc length of the arc-shaped buffer pad 42 is greater than half a circle. The outer diameter of the support ball 45 is equal to the inner diameter of the arc-shaped buffer pad 42, and the support ball 45 is in contact with the inner annular surface of the distribution body 1.

The deformation of the arc-shaped buffer can further reduce the impact on the distribution body 1.
