[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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 the embodiments.

[0018] According to Figure 1-2As shown in the figure, a household water heater with a filtering function includes a first pipeline 1 and a second pipeline 2. An installation box 3 is fixedly installed between the first pipeline 1 and the second pipeline 2. The connection methods between the first pipeline 1 and the second pipeline 2 and the installation box 3 have been fully disclosed in the prior art, so no more details will be given here. The installation box 3 is hollow. A transmission cylinder 4 is rotatably installed on the installation box 3. A filter screen is fixedly installed at one end of the transmission cylinder 4. A push rod 5 is sleeved at the other end of the transmission cylinder 4. A scraping plate 6 is arranged at one end of the push rod 5. An arc-shaped groove 7 is formed on the wall of the transmission cylinder 4. A connecting rod 8 is slidably connected in the arc-shaped groove 7. One end of the connecting rod 8 is fixedly connected to the push rod 5.

[0019] The scraping plate 6 is in a circular ring shape. Chamfers are arranged on the inner circles of the scraping plate 6. The outer circle of the scraping plate 6 is in contact connection with the inner wall of the second pipeline 2. Such a setting can better clean the inner wall of the second pipeline 2.

[0020] A sliding groove is arranged in the installation box 3. The connecting rod 8 is slidably installed in the sliding groove. Such a setting can limit the connecting rod 8 and ensure that the connecting rod 8 moves linearly.

[0021] A baffle 9 and a rotating plate 10 are respectively installed on the transmission cylinder 4. The baffle 9 and the rotating plate 10 are respectively located on both sides of the installation box 3.

[0022] Two inserting rods are fixedly installed on the inner wall of the upper part of the first pipeline 1. Two inserting slots 11 are formed on the rotating plate 10. The inserting rods are in mating connection with the inserting slots 11. Such a setting can limit the rotating plate 10 and ensure that the rotating plate 10 does not rotate when the filter screen is working.

[0023] A passage is formed among the first pipeline 1, the filter screen, the transmission cylinder 4, the push rod 5, the scraping plate 6 and the second pipeline 2. Such a setting can not interfere with the normal work of the first pipeline 1 and the second pipeline 2.

[0024] Working principle: When maintaining the filter screen, first separate the connection between the installation box 3 and the first pipeline 1, separate the inserting rod from the inserting slot 11, rotate the rotating plate 10, control the rotation of the transmission cylinder 4. The arc-shaped groove 7 drives the push rod 5 to move linearly under the action of the sliding groove. The push rod 5 pushes the scraping plate 6 to clean the inside of the second pipeline 2. Then separate the connection between the installation box 3 and the second pipeline 2, and subsequent cleaning and maintenance can be carried out on the second pipeline 2 and the filter screen.

[0025] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
