[0002] In the current field of interior decoration, ceiling curtains are a common decorative element and are widely used in various places, such as conference rooms, exhibition halls, family living rooms, etc. Their unique design and visual effects add a touch of brightness to the interior space. However, the traditional ceiling curtain design has also exposed some problems and shortcomings in the actual application process.

[0003] First, the existing ceiling curtain design often exposes a black horizontal bar at its bottom to support the curtain and enable it to be rolled up or unfolded smoothly; however, this design detail often does not match the overall color or decoration style of the ceiling. Especially in a light or bright color decoration environment, the black horizontal bar looks particularly abrupt, destroying the harmony and beauty of the overall decoration; this visual disharmony not only affects the overall aesthetics of the room, but also brings unnecessary visual interference to users;

[0004] Secondly, during the long-term use of existing ceiling curtains, dust and other impurities are easily accumulated on their surfaces, and the presence of these impurities not only affects the visual effect of the ceiling curtain, but may also have a certain negative impact on the indoor air quality. However, since the traditional ceiling curtain design does not take the convenience of cleaning into consideration, users face many difficulties in cleaning these dust. On the one hand, due to the high position of the ceiling curtain, it is difficult to reach directly. On the other hand, even if it can be reached, due to the lack of a special cleaning mechanism, the cleaning process is often time-consuming and labor-intensive and the effect is not good.

[0005] Therefore, it is necessary to provide a new closed ceiling curtain to solve the above technical problems. Utility Model Content

[0036] The working principle of the enclosed ceiling curtain provided by the present utility model is as follows:

[0037] I. Overview of the working principle

[0038] The working principle of this enclosed ceiling curtain is based on the upward movement of the curtain 2. This movement realizes the automatic closing of the enclosed cover 4 through a series of mechanical transmission mechanisms, and at the same time drives the cleaning roller 6 to rotate to remove the floating dust and impurities on the surface of the curtain 2.

[0039] II. Detailed working principle

[0040] Raising of the curtain and closing of the enclosed cover

[0041] When the system is started, the motor 71 starts to work, and its output end drives the driving gear 72 to rotate.

[0042] The driving gear 72 meshes with the driven gear 74 at one end of the connecting rod 73, thereby driving the connecting rod 73 to rotate. Since the curtain 2 is wound around the outer wall of the connecting rod 73, the rotation of the connecting rod causes the curtain 2 to start rising.

[0043] The rack 3 on the back of the curtain 2 moves as the curtain rises. The rack 3 remains in meshing engagement with the gear 5 fixed in the middle of the closed cover 4. The rising of the rack 3 drives the gear 5 to rotate, and then drives the entire closed cover 4 to rotate around its connection point with the frame 1.

[0044] A torsion spring 9 is installed between the closed cover 4 and the ear plate 8 on the back of the frame 1. The torsion spring 9 exerts an outward elastic force on the closed cover 4 in the initial state, keeping the closed cover 4 in an open state. However, as the gear 5 rotates, the closed cover 4 gradually overcomes the elastic force of the torsion spring 9 and closes towards the bottom of the frame 1, finally completely covering the bottom of the frame to achieve a sealing effect.

[0045] The cleaning roller works

[0046] While the curtain 2 is rising, the motor 71 also transmits power to the cleaning roller 6 through the meshing relationship between the driving bevel gear 75 and the driven bevel gear 76.

[0047] The driving bevel gear 75 is fixed at the axis of the driving gear 72 and rotates together with the driving gear 72. The rotation of the driving bevel gear 75 drives the meshing driven bevel gear 76 to rotate, and the driven bevel gear 76 then drives the cleaning roller 6 to rotate.

[0048] The bristles on the outside of the cleaning roller 6 are tangent to the surface of the curtain 2. As the cleaning roller 6 rotates, frictional force is generated between the bristles and the surface of the curtain 2, thereby removing the floating dust and impurities on the surface of the curtain 2.

[0049] The cleaning process is synchronized with the rising process of the curtain, ensuring that the curtain 2 is effectively cleaned while being rolled up.

[0050] Other auxiliary designs and functions

[0051] The weighted crossbar 10 is fixed at the bottom of the curtain 2, increasing the weight and stability of the curtain, and preventing the curtain from shaking due to wind or other external forces during the rising process.

[0052] The color of the closed cover 4 is the same as that of the wall, aiming to eliminate the visual abruptness and enhance the overall decorative effect.

[0053] The frame 1 is installed on the bracket, and the bracket is fixed on the ceiling surface to ensure the stable installation of the entire system.

[0054] The rack 3 is made of rubber material, which may be to increase the friction between the rack and the gear 5, improve the stability and reliability of the transmission, and reduce noise.

[0055] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
