DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0018] Reference Figures 1 to 4 As shown, in order to achieve the above purpose, the utility model provides the following technical solutions: a domestic water tank, comprising a water tank body 1 and a filter body 2, the filter body 2 is detachably mounted on one side of the water tank body 1, the water tank body 1 is provided with a water inlet 11, the filter body 2 is provided with a water inlet pipe 3, a water outlet pipe 4 and a cleaning pipe 5, the filter body 2 is connected with the water inlet 11 through the water outlet pipe 4;

[0019] The cleaning pipe 5 is externally connected to a cleaning water source, and the cleaning pipe 5 is located below the water outlet pipe 4;

[0020] The filter body 2 is provided with an inner cylinder 21 and a filter membrane 22. A plurality of drain ports 23 are provided on the periphery of the inner cylinder 21. The filter membrane 22 is provided on the inner wall of the inner cylinder 21. The upper end of the inner cylinder 21 is connected to the water inlet pipe 3.

[0021] A cleaning component 7 is arranged outside the inner cylinder 21 and / or inside the inner cylinder 21 .

[0022] The embodiments of the cleaning component 7 include: Embodiment 1, such as Figure 3 As shown, only the extrusion plate 71 and the electric push rod 72 are arranged outside the inner cylinder 21;

[0023] Embodiment 2, as Figure 4 As shown, an extrusion plate 71 and an electric push rod 72 are arranged outside the inner cylinder 21, and a cleaning brush 74, a rotating rod 75 and a driving motor 76 are arranged inside the inner cylinder 21;

[0024] In the third embodiment (not shown in the figure), only a cleaning brush 74 , a rotating rod 75 and a driving motor 76 are arranged in the inner cylinder 21 .

[0025] According to the design of the utility model, the filter body 2 is installed on one side of the water tank body 1, so that the water outlet pipe 4 is aligned with and inserted into the water inlet 11, and water enters the filter body 2 through the water inlet pipe 3, and then passes through the double filtering effect of the filter membrane 22 and the inner cylinder 21 (that is, the existing filter element), and finally flows into the water tank body 1 through the water outlet pipe 4.

[0026] When the filter body 2 needs to be cleaned or replaced, the filter body 2 can be separated from the water tank body 1. At this time, the inside of the water tank body 1 can operate independently, and the water inside can still be used continuously.

[0027] The filter body 2 can be cleaned separately without draining the water in the water tank body 1, thereby avoiding the waste of water resources, and the water retained in the filter body 2 can be used for cleaning, thereby improving the utilization rate of water resources.

[0028] The inner cylinder 21 is reversely cleaned by the cleaning component 7 to achieve the cleaning effect on the filter body 2, thereby increasing the service life of the filter body 2, and after the cleaning is completed, the sewage can be discharged through the cleaning pipe 5 or the water inlet pipe 3.

[0029] A sealing cover is hingedly connected to the inner side of the water inlet 11. The design of the sealing cover can seal the inner side of the water inlet 11 when the water outlet pipe 4 is separated from the water inlet 11, thereby playing a certain dustproof role.

[0030] The outlet pipe 4 is provided with an outlet valve 41, and the cleaning pipe 5 is provided with a cleaning valve 51. The design of the cleaning valve 51 and the outlet valve 41 can respectively control the flow or cutoff of the corresponding pipe body.

[0031] A stand 6 is provided on the outside of the filter body 2, and the filter body 2 is rotatably connected to the stand 6. In the design of the structure, by inverting the filter body 2, water is injected into the filter body 2 through the cleaning water source from the cleaning pipe 5, and the water flows into the inner cylinder 21 through the drain port 23, and continuously flushes the inner cylinder 21 and the filter membrane 22, and the stains originally accumulated on the inner cylinder 21 and the filter membrane 22 are flushed out from the position of the water inlet pipe 3.

[0032] The filter body 2 and the water tank body 1 are provided with detachable connecting pieces.

[0033] The connector includes a connector block and a connector buckle. The connector block is arranged on both sides of the water tank body 1, and the connector buckle is hingedly arranged on both sides of the filter body 2. The connector is designed so that when the filter body 2 and the water tank body 1 are installed correspondingly, the connector is buckled with the connector block through the connecting port, so that the two are relatively fixed, thereby avoiding unnecessary rotation of the filter body.

[0034] The cleaning component 7 includes a squeeze plate 71 and an electric push rod 72. The squeeze plate 71 is slidably connected between the inner tube 21 and the filter body 2, and the extended end of the electric push rod 72 is abutted against the squeeze plate 71. The electric push rod is a prior art, which adopts a screw rod and a motor structure and can stably push the squeeze plate to move vertically.

[0035] An extension plate 24 is disposed outside the upper end of the inner cylinder 21 . A tension spring 73 is sleeved outside the inner cylinder 21 . One end of the tension spring 73 is connected to the extension plate 24 , and the other end is connected to the extrusion plate 71 .

[0036] With this structural design, when the space between the inner cylinder 21 and the filter body 2 is filled with water, the capacity space is compressed by pushing the squeezing plate 71, so that water flows into the inner cylinder 21, thereby playing a flushing role.

[0037] When the electric push rod 72 is reset, the extrusion plate 71 moves upward under the action of the tension spring 73. At this time, the capacity space between the inner cylinder 21 and the filter body 2 increases, and the water flow will be gathered outside the inner cylinder 21 again. Therefore, during the repeated movement of the extrusion plate 71, the inner cylinder 21 and the filter membrane 22 are continuously flushed, thereby achieving an efficient cleaning effect.

[0038] The cleaning component 7 includes a cleaning brush 74 and a rotating rod 75 and a driving motor 76 arranged in the inner cylinder 21. The driving motor 76 is used to drive the rotating rod 75 to rotate. There are multiple groups of cleaning brushes 74, which are arranged in a height direction of the rotating rod 75.

[0039] The design of this structure can control the rotation of the rotating rod 75 by driving the motor 76, so that the cleaning brush 74 can continuously clean the filter membrane 22 and the inner side of the inner cylinder 21, thereby improving the cleaning effect.

[0040] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
