[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-3 In this embodiment of the utility model, the dust-proof double air curtain machine includes a housing 1, one end of which is integrally formed with a mounting housing 2, which provides installation space for the fan. Two air vents 3 are opened at the bottom of the housing 1. Two hollow filters 7 are rotatably installed inside the housing 1. An intermediate connector 8 is fixedly installed between the two hollow filters 7. The two ends of the intermediate connector 8 are tapered to the middle. A transmission mechanism connected to the intermediate connector 8 is installed at the top of the housing 1. A dust removal mechanism extending into the interior of the two hollow filters 7 is installed at the end of the housing 1 away from the mounting housing 2. A connecting groove 5 with a semi-circular cross-section is opened at the joint between the mounting housing 2 and the housing 1.

[0015] In this embodiment: When the device is activated, the fan located inside the mounting housing 2 is started. The fan draws outside air into the interior of the mounting housing 2. The drawn-in air enters the lower half of the hollow filter 7 through the semi-circular connecting groove 5. After being filtered by the hollow filter 7, the air is blown downward through the two air outlets 3 to form two air curtains to block the communication between the inside and outside air, thereby maintaining the indoor temperature and the cleanliness of the indoor air. After the device has been in operation for a period of time, the transmission mechanism is activated, which drives the intermediate connector 8 and the two hollow filters 7 to rotate. At the same time, the dust removal mechanism is activated, which sucks out the dust and impurities attached to the inner wall of the hollow filters 7, so as to avoid the accumulation of impurities that would cause poor airflow from the air outlet 3, thus resulting in poor air curtain effect.

[0016] Please refer to this carefully. Figure 1 and Figure 2 The transmission mechanism includes a driven synchronous pulley 9 mounted in the middle section of the intermediate connector 8, and a geared motor 11 mounted on the top plate of the housing 1. The output end of the geared motor 11 is coaxially fixedly mounted with a driving synchronous pulley 10. The driven synchronous pulley 9 and the driving synchronous pulley 10 are connected by a synchronous belt 12.

[0017] In this embodiment: by starting the reduction motor 11, the reduction motor 11 drives the active synchronous wheel 10 to rotate. The rotating active synchronous wheel 10 drives the driven synchronous wheel 9 to rotate via the synchronous belt 12. The rotating driven synchronous wheel 9 drives the two hollow filters 7 to rotate via the intermediate connector 8, so that the inner circumference of the hollow filters 7 can rotate to directly above the dust removal mechanism.

[0018] Please refer to this carefully. Figure 2 and Figure 3 The dust removal mechanism includes a partition 6 fixedly installed at both ends of the inner wall of the outer shell 1 and located in the inner cavity of the hollow filter 7 and the intermediate connector 8. The partition 6 divides the inner cavity of the hollow filter 7 into upper and lower parts. The dust removal mechanism also includes a dust removal pipe 4 that extends from the outside of one end of the outer shell 1 into the inside of the outer shell 1 and is located in the upper half of the inner cavity of the hollow filter 7. The dust removal pipe 4 has dust removal holes 13 that are equidistantly opened on it and face upward. The output end of the dust removal pipe 4 is connected to the suction fan through a pipe.

[0019] In this embodiment: when the two hollow filters 7 are rotating, the suction fan is started, and the suction fan generates negative pressure. At this time, the air inside the upper part of the hollow filter 7 is sucked into the dust removal pipe 4 under negative pressure. During the air circulation, the impurities attached to the inner wall of the hollow filter 7 enter the dust removal pipe 4 through the dust removal hole 13 and are discharged outward through the pipe. This achieves the discharge of impurities intercepted inside the hollow filter 7 without the need for disassembly and cleaning.

[0020] Please refer to this carefully. Figure 3 The inner cavity of the outer shell 1 is fixedly installed with two intercepting plates 14 that are rotatably mounted with the intermediate connector 8. The top plate of the outer shell 1 is provided with a groove for the synchronous belt 12. The two intercepting plates 14 are located on the outside of the two sides of the groove to prevent gas from moving out through the groove.

[0021] In this embodiment: by means of the above method, air can be prevented from overflowing outward through the tank, ensuring that air can only be blown downward through the air outlet 3, thus ensuring the wind force of the air curtain.

[0022] 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.
