[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Embodiment 1:

[0024] As shown in Figures 1-5 , a filter valve member that can be quickly disassembled includes a first pipeline 1 and a second pipeline 2. A filter screen 6 is arranged between the first pipeline 1 and the second pipeline 2. An installation cylinder 3 is sleeved on the first pipeline 1. The installation cylinder 3 is hollow, and the side and both ends of the installation cylinder 3 are open. Two baffles 8 are arranged at the open end of the installation cylinder 3. An installation plate 5 is sleeved on the second pipeline 2. Two cylinders 4 are symmetrically and fixedly installed on the installation plate 5. The output shafts of the two cylinders 4 are respectively in contact connection with the bottom surface of the baffle 8. Here, the cylinder 4 can maintain pressure.

[0025] Arc-shaped insertion plates 10 are arranged on both sides of the filter screen 6. Sealing rings are arranged on both sides of the arc-shaped insertion plates 10, which can increase the sealing performance while preventing water. The filter screen 6 is inserted into the first pipeline 1 and the second pipeline 2 respectively through the arc-shaped insertion plates 10. Such a setting can ensure the accurate installation of the filter screen 6.

[0026] A limiting post is arranged in the installation cylinder 3, and the limiting post cooperates with the limiting groove on the first pipeline 1. Such a setting can limit the installation cylinder 3 and prevent the installation cylinder 3 from rotating during work.

[0027] Identifications 7 are arranged on both the first pipeline 1 and the installation cylinder 3. When the identifications 7 on the first pipeline 1 and the installation cylinder 3 are aligned, it can ensure that the baffle 8 accurately passes through the through slot 9.

[0028] The two cylinders 4 pass through the side opening of the installation cylinder 3 and are fixedly installed on the installation plate 5, ensuring the maintenance of the cylinders 4.

[0029] Two through slots 9 are opened on the installation plate 5. The through slots 9 are equal in size to the baffle 8. Such a setting can facilitate the disassembly of the installation cylinder 3 and ensure that the baffle 8 can move in the through slot 9.

[0030] Working principle: When it is necessary to disassemble the filter screen 6, the cylinder 4 contracts, the output shaft of the cylinder 4 is separated from the installation cylinder 3, the installation cylinder 3 is moved to the side of the first pipeline 1, the limiting post is separated from the limiting groove, the installation cylinder 3 is rotated, the identifications 7 on the first pipeline 1 and the installation cylinder 3 are aligned, the baffle 8 accurately passes through the through slot 9, and the installation cylinder 3 is removed from the second pipeline, so that the first pipeline 1 and the second pipeline 2 can be separated to facilitate the removal of the filter screen 6.

[0031] Embodiment 2:

[0032] A household water heater is applied to the filter valve member that can be quickly disassembled described in Embodiment 1.
