[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figures 1 to 3 As shown, an embodiment of the present application provides a device for painting interior walls of a building, comprising a primary handle 2, a bracket 1 fixedly connected to the top of the primary handle 2, and a paint roller 4 rotatably connected to the bracket 1. The primary handle 2 is a tubular member with an opening at one end and a hollow interior, and also comprises a secondary handle 3 detachably connected to the opening of the primary handle 2, wherein the secondary handle 3 is suitable for blocking the opening of the primary handle 2 so that a liquid storage chamber 21 is formed inside the primary handle 2. A nozzle 5 is provided on the bracket 1 facing the paint roller 4, and a conveying assembly for conveying the paint in the liquid storage chamber 21 to the nozzle 5 is connected between the liquid storage chamber 21 and the nozzle 5. A collecting tank 6 is provided on the bracket 1 below the paint roller 4, and the collecting tank 6 is communicated with the liquid storage chamber 21.

[0020] When the above-mentioned painting device is working, the paint is first poured into the primary handle 2, and then the secondary handle 3 is connected and fixed to the primary handle 2 so that the paint can be sealed and confined in the liquid storage chamber 21, and then the conveying component is started, and the nozzle 5 sprays the paint toward the painting roller 4. Finally, the painting roller 4 is pushed to rotate along the wall by manually holding the handle to complete the painting of the wall. The paint dropped during the painting process can be collected by the collection tank 6 into the liquid storage chamber 21.

[0021] In the above manner, by setting the liquid storage chamber 21 in the primary handle 2, the overall weight of the paint will not be concentrated on the head of the painting device, which is not easy to cause fatigue of the operator and is conducive to improving work efficiency. In addition, by setting the collecting tank 6, during the painting process, excess paint can be recovered by the collecting tank 6 into the liquid storage chamber 21 for recycling, which can prevent the paint from dripping onto the operator or the ground, thereby reducing the waste of paint.

[0022] In this embodiment, the conveying assembly includes a water pump 9 and a power supply module for supplying power to the water pump 9. The output end of the water pump 9 is connected to the nozzle 5 through an output pipe, and the input end of the water pump 9 is connected to an input pipe 8. The input pipe 8 extends along the liquid storage chamber 21 to a side close to the secondary handle 3.

[0023] Specifically, the power module includes a lithium battery 10, a female socket and a switch 11. The secondary handle 3 is defined with a battery compartment and a mounting slot. The lithium battery 10 is arranged in the battery compartment, and the switch 11 is fixed in the mounting slot. The lithium battery 10, the switch 11 and the female socket are electrically connected in sequence. The water pump 9 is electrically connected with a male plug, and the male plug is pluggably connected to the female socket.

[0024] During operation, the primary handle 2 and the secondary handle 3 can be manually shaken to mix the paint evenly, which is beneficial to the extraction of the water pump 9. After use, clean water can be poured into the primary handle 2, and the water pump 9 can be started to clean the entire painting device, which can effectively avoid clogging of the painting device.

[0025] In this embodiment, a one-way valve is provided on the primary handle 2 to maintain a pressure balance between the inside and outside of the liquid storage chamber 21. By providing the one-way valve, the problem of excessive or insufficient pressure in the liquid storage chamber 21 is not likely to occur.

[0026] In this embodiment, the opening of the primary handle 2 is detachably connected to the secondary handle 3 via a detachable connection structure, and the detachable connection structure includes an internal thread provided on the opening of the primary handle 2 and an external thread provided on the secondary handle 3, and the external thread is adapted to the internal thread. The arrangement of the external thread and the internal thread makes the connection between the primary handle 2 and the secondary handle 3 more convenient and quick, and has the advantage of good connection sealing.

[0027] In this embodiment, the collecting trough 6 is hinged to the bracket 1, and the collecting trough 6 includes a bottom and an opening. A counterweight block is provided at the bottom of the collecting trough 6, and the counterweight block is suitable for driving the bottom plane of the collecting trough 6 to always remain parallel to the ground. The bottom of the collecting trough 6 is provided with a drop port connected to its opening, and the drop port is connected to the liquid storage chamber 21 through a hose 7.

[0028] In the above manner, the counterweight block is arranged so that the collecting trough 6 can be similar to the principle of a "tumbler" and always keep its bottom surface parallel to the ground. In this way, when the painting device is in an inclined state, the opening of the collecting trough 6 can always remain in a vertical upward state, and will not weaken the paint collection capacity, thereby realizing all-round paint recovery.

[0029] In this embodiment, a filter screen is provided at the inner bottom of the collecting tank 6. Through the provision of the filter screen, impurities in the recovered paint can be effectively filtered, which is beneficial to improving the quality of the secondary use.

[0030] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
