Description

Technical Field

[0001] This utility model relates to the field of electric roller blind technology, and in particular to a roller blind with dustproof function. Background Technology

[0002] Roller blinds are a type of window covering system that uses a roller tube to raise and lower the entire curtain fabric. They are widely used in office, home, and commercial spaces. The control methods for roller blinds are divided into manual and electric, such as the common beaded manual roller blinds and electric roller blinds driven by tubular motors.

[0003] When the roller blind is in the unfolded state, the curtain is exposed to the outside of the roller blind box for a long time, which easily leads to dust adhering to the surface, especially fabric curtains. The curtain is inconvenient to disassemble and clean, which causes dust and other dirt to accumulate on the surface of the curtain. This not only affects the decoration of the interior space, but the dust on the surface of the curtain can also easily cause respiratory discomfort to people. Utility Model Content

[0004] The purpose of this utility model is to provide a roller blind with a dustproof function to solve the problem of inconvenient cleaning after dust accumulates on the curtain of existing electric roller blinds.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a roller shutter with dustproof function, comprising:

[0006] The roller blind body includes a roller blind box, a winding assembly, a curtain fabric, and a counterweight rod. The winding assembly is located inside the roller blind box and is used to drive the roller drum to rotate. The curtain fabric is wound around the roller drum, and one end of the curtain fabric passes through the roller blind box and connects to the counterweight rod.

[0007] The dust removal assembly includes a dust removal housing, a dust collection bin, an impeller, a motor, and a suction nozzle. The dust removal housing is provided with an exhaust hole, and the suction nozzle faces the curtain. The suction nozzle is connected to the dust collection bin through a corrugated pipe. The dust collection bin is provided with a filter element, and the impeller is fixedly mounted on the output shaft of the motor.

[0008] As a further description of the above technical solution:

[0009] The roller shutter box has symmetrically arranged guide rails on both sides. The guide rails are fixedly installed on the window frame, and the counterweight rod is slidably connected to the guide rails.

[0010] As a further description of the above technical solution:

[0011] The counterweight bar is equipped with a connecting seat, which is slidably connected to the guide rail.

[0012] As a further description of the above technical solution:

[0013] The connecting seat is detachably mounted on the counterweight bar.

[0014] As a further description of the above technical solution:

[0015] The connector is equipped with a buckle, and the counterweight bar is fastened in the buckle.

[0016] As a further description of the above technical solution:

[0017] The counterweight rod is a round metal rod.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, when the roller blind body is retracted, the retracting assembly drives the roller to rotate, and the curtain is wound on the roller. The counterweight rod at the bottom of the curtain rises accordingly. During the curtain retraction process, the motor of the dust removal assembly drives the impeller to rotate, generating negative pressure in the dust collection chamber. The dust suction nozzle adsorbs the dust on the surface of the curtain and delivers it to the dust collection chamber through the corrugated pipe. After the airflow separates the dust through the filter, it is discharged from the dust collection chamber and discharged from the dust removal shell through the exhaust hole. The dust is cleaned in time after each use of the roller blind to keep the surface of the curtain clean.

[0020] 2. In this utility model, the counterweight rod can effectively ensure the hanging state of the curtain and prevent the dust suction nozzle from affecting the curtain's winding. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figure 1-6 This utility model provides a technical solution: a roller blind with dustproof function, comprising:

[0034] The roller blind body 1 includes a roller blind box 11, a winding assembly 12, a curtain 13 and a counterweight rod 14. The winding assembly 12 is disposed inside the roller blind box 11 and is used to drive the roller drum 121 to rotate. The curtain 13 is wound around the roller drum 121, and one end of the curtain 13 passes through the roller blind box 11 and is connected to the counterweight rod 14.

[0035] The dust removal assembly 2 includes a dust removal housing 21, a dust collection chamber 22, an impeller 23, a motor 24, and a suction nozzle 25. The dust removal housing 21 is provided with an exhaust hole 211, and the suction nozzle 25 faces the curtain 13. The suction nozzle 25 is connected to the dust collection chamber 22 through a corrugated pipe 251. The dust collection chamber 22 is provided with a filter element 221, and the impeller 23 is fixedly installed on the output shaft of the motor 24.

[0036] The roller shutter box 11 is provided with symmetrically arranged guide rails 15 on both sides. The guide rails 15 are fixedly installed on the window frame, and the counterweight rod 14 is slidably connected to the guide rails 15 to further prevent the suction of the dust nozzle 25 from causing the curtain 13 to deform and the dust removal from affecting the rolling of the curtain 13.

[0037] Working principle: When the roller blind body 1 is retracted, the retraction assembly 12 drives the roller drum 121 to rotate, and the curtain fabric 13 is wound onto the roller drum 121. The counterweight rod 14 at the bottom of the curtain fabric 13 rises accordingly. During the retraction process of the curtain fabric 13, the motor 24 of the dust removal assembly 2 drives the impeller 23 to rotate, generating negative pressure in the dust collection chamber 22. The suction nozzle 25 adsorbs the dust on the surface of the curtain fabric 13 and delivers it to the dust collection chamber 22 through the corrugated pipe 251. After the airflow passes through the filter element 221 to separate the dust, it is discharged from the dust collection chamber 22 and discharged from the dust collector shell 21 through the exhaust hole 211. The dust is cleaned in time after each use of the roller blind to keep the surface of the curtain fabric clean. The counterweight rod 14 can effectively ensure the hanging state of the curtain fabric 13 and prevent the dust adsorption of the suction nozzle 25 from affecting the retraction of the curtain fabric 13.

[0038] Example 2

[0039] Based on the above embodiments, this embodiment further improves upon the following technical solution: a connecting seat 16 is provided on the counterweight rod 14, the connecting seat 16 is slidably connected to the guide rail 15, and the connecting seat 16 is detachably installed on the counterweight rod 14.

[0040] The connecting seat 16 is provided with a buckle 161, and the counterweight rod 14 is fastened in the buckle 161. The counterweight rod 14 is slidably connected to the guide rail 15 through the buckle 161, and the buckle 161 enables the connecting seat 16 and the counterweight rod 14 to be detached and installed, making it easy to separate the counterweight rod 14 from the guide rail 15 for subsequent maintenance.

[0041] Example 3

[0042] Based on the above embodiments, this embodiment further improves upon the following technical solution: the counterweight rod 14 is a metal round rod.

[0043] On the one hand, it ensures the weight of the counterweight rod 14, and on the other hand, it makes the counterweight rod 14 less prone to deformation, thus ensuring the quality of the fastening with the connecting seat 16.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
