The utility model has a simple structure, is easy to use, and the curtain is protected from being easily contaminated and can be automatically cleaned.

[0004] When the voice curtain in the above technology is in use, although the cleaning brush arranged at the opening at the bottom end of the installation box can clean the sliding surface of the curtain body, when the extrusion pressure between the cleaning brush and the curtain body is too small, it will affect the cleaning effect of the cleaning brush on impurities on the surface of the curtain body. When the fitting force between the cleaning brush and the curtain body is too large, it will produce greater resistance to the release of the curtain body, and the weight of the counterweight block needs to be increased, but this will also increase the power of the motor. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a voice curtain described in the present invention includes a storage box; a motor is installed at one end inside the storage box, the output end of the motor is connected to a rotating rod, a curtain body is wound on the rotating rod, a retractable opening is arranged on the bottom surface of the storage box, the free end of the curtain body passes through the retractable opening and is connected to a counterweight block, the motor is electrically connected to a central processing unit through an electric control module, the central processing unit signal is connected to a voice acquisition module, and a plurality of groups of elastic strips are symmetrically arranged at the side walls of the retractable opening on both sides of the curtain body, the elastic strips are arc-shaped and their free ends are bent downward The cross-sectional width of the vertical surface of the elastic strip gradually increases from the free end to the connecting end, and a cleaning strip capable of scraping the surface of the curtain body is connected to the top surface of the free end of the elastic strip; when the voice curtain in the prior art is in use, although the cleaning brush arranged at the opening at the bottom end of the installation box can clean the sliding surface of the curtain body, when the extrusion force between the cleaning brush and the curtain body is too small, it will affect the cleaning effect of the cleaning brush on impurities on the surface of the curtain body; when the adhesion force between the cleaning brush and the curtain body is too large, it will produce greater resistance to the release of the curtain body, and the weight of the counterweight block needs to be increased, but this will also increase the motor Power; when the voice curtain of the present invention is in use, the voice collection module can be placed in a convenient position. When the curtain needs to work, the signal is transmitted to the central processor through voice, and the motor is controlled by the electronic control module, so that the motor releases the rolled-up curtain body by driving the rotation of the rotating rod, thereby making the use of the curtain more intelligent and convenient. When the curtain body is not needed to work, the curtain body can be rolled up by reversing the motor (which can be set as a servo motor). In this process, the cleaning strip at the end of the elastic strip can fit tightly with the surface of the curtain body, and the cleaning strip can be used to remove dust and impurities on the surface of the curtain body. For cleaning, the shape of the elastic strip is set so that the free end of the elastic strip can be easily deflected downward but difficult to tilt upward, that is, when the curtain body moves downward from the elastic strip, the free end of the elastic strip exerts less force on the curtain body, thereby reducing the resistance generated by the cleaning component to the release of the curtain body, and when the curtain body moves upward between the two elastic strips, the end of the elastic strip will exert a greater reverse force on the curtain body, so that the cleaning strip can be used to scrape and clean the surface of the curtain body more effectively, that is, the different movement directions of the curtain body can be used to adjust the force between the cleaning component and the curtain body, thereby improving the practical effect of the curtain.

[0007] Preferably, the connecting end of the elastic strip is rotatably connected to the side wall of the storage opening via a torsion spring, and a limiting strip is connected to the side wall of the storage opening at the top of the elastic strip; the elastic strip is rotatably connected to the storage opening via the torsion spring, so that the free end of the elastic strip can be rotated downward more easily, thereby reducing the resistance of the elastic strip to the curtain body when it is lowered, and at the same time, when the curtain body slides upward, the curtain body can drive the free end of the elastic strip to swing upward, and at the same time, the limiting strip can resist the elastic strip and limit it, so that the elastic strip can exert a larger extrusion force on the curtain body, thereby improving the cleaning effect of the curtain body surface.

[0008] Preferably, under the action of its own gravity and the torsion spring, there is a gap between the free end of the elastic strip and the curtain body, and a first magnetic block is arranged on the elastic strip. When the curtain body is in a released state, an adsorption strip is connected to the position of the top surface of the curtain body corresponding to the elastic strip, and the free end of the limit strip is connected to the adsorption block, and the first magnetic block can be attracted to the adsorption strip and the adsorption block respectively; when the elastic strip is in a natural state, there is a gap between its free end and the curtain body, and at this time, the curtain body will not be resisted by the elastic strip when it is lowered, which further improves the smoothness of the curtain body when it is released, and is also beneficial to the heat dissipation of the motor inside the storage box. At the same time, when the curtain body starts to roll up, the adsorption strip arranged on its top moves to the elastic strip, and can be attracted to the first magnetic block, and drive the free end of the elastic strip to swing upward, until the first magnetic block of the elastic strip moves to the position of the adsorption block and is adsorbed and fitted with it. At this time, the elastic strip can be closely fitted with the curtain body under the action of the first magnetic block and the adsorption block, as well as the friction force of the curtain body, thereby having a cleaning effect on the surface of the curtain body.

[0009] Preferably, an arc-shaped groove is arranged on the side wall of the elastic strip at the top of the cleaning strip, a rolling column with a matching shape is rotatably connected inside the arc-shaped groove, the side wall of the rolling column can fit with the surface of the curtain body, a group of annularly evenly distributed second magnetic blocks are inlaid and installed on the side wall of the rolling column, a cavity is opened inside the elastic strip corresponding to the bottom end of the arc-shaped groove, an elastic film is connected to the end of the cavity close to the rolling column, an elastic member is connected between the elastic film and the end of the cavity away from the rolling column, a magnetic member capable of interacting with the second magnetic block is connected to the surface of the elastic film, and the elastic strip is self-locking. A nozzle connected to the cavity is arranged on the bottom surface of the end, and the jet direction of the nozzle is toward one side of the curtain body; when the curtain body slides upward, the friction force on the fitted rolling column can drive the rolling column to rotate continuously, so that the rolling column drives the second magnetic block on the surface to continuously pass through the magnetic part, so that the attraction between the two can drive the elastic membrane to agitate in the cavity after intermittent changes, so that the gas inside it can be sprayed onto the surface of the curtain body through the nozzle, so that the impurities on the surface of the curtain body can be blown off and pre-cleaned before being cleaned by the cleaning strip, thereby improving the cleaning quality of the curtain surface.

[0010] Preferably, a push rod is installed at the side wall position of the storage box opposite to the motor, the rotating rod is a hollow tube, the telescopic rod of the push rod extends to the inside of the rotating rod and is connected to an electromagnet, a plurality of sets of sliding sleeves are slidably connected to the outer wall of the rotating rod, and an elastic bellows is connected between two adjacent sliding sleeves, the electromagnet can attract the sliding sleeve when working, and the connecting end of the curtain body is fixedly connected to the side wall of the sliding sleeve; when the curtain body is completely released, if it is necessary to adjust the shielding area of ​​the curtain body, at this time, by adjusting the movement of the push rod inside the rotating rod, and then controlling the operation of the electromagnet to attract the sliding sleeve, and then by adjusting the sliding of the push rod inside the curtain body, the electromagnet drives the curtain body on the sliding sleeve to move toward one end, thereby pulling the curtain body and adjusting the shielding area.

[0011] Preferably, an arc-shaped slot is provided at the top surface position of the counterweight block corresponding to the elastic strip, and the shape of the slot matches the shape of the elastic strip; when the curtain body is fully rolled up, the slot at the counterweight block can engage with the elastic strip under the pulling of the curtain body, thereby sealing the gap between the counterweight block and the storage box, further reducing the accumulation of dust and contamination inside the storage box.

[0012] Preferably, the cleaning strip is made of sponge material, a water pump that can be connected to an external water source is installed inside the counterweight block, a conducting groove connecting the water pump and the card slot is opened inside the counterweight block, a flushing groove is opened inside the elastic strip, and when the elastic strip cooperates with the card slot, the flushing groove can connect the conducting groove and the side wall of the elastic strip at the cleaning strip, and a drainage groove connected to the outside is opened at the arc groove on one side of the cleaning strip; when the cleaning strip made of sponge material cleans the surface of the curtain body for a long time, a large amount of dust and impurities accumulate on its surface and inside, if it is not effectively cleaned, it will affect the subsequent cleaning effect of the curtain body. At this time, it is only necessary to connect the water pump to the external water source, so that the water pump pumps clean water into the cleaning strip position through the conducting groove and the flushing groove, so that the dust and impurities accumulated at the cleaning strip can be flushed down through the drainage groove, thereby improving the subsequent cleaning quality of the curtain body by the cleaning strip.

[0013] Preferably, the water inlet end of the drainage trough is provided with a funnel-shaped portion which is wide in the middle and narrow at both ends, and the inner end of the funnel-shaped portion is provided with a recessed portion; when the water flow impacts the cleaning strip, the cleaning strip will pass through the narrower funnel-shaped portion under the action of the water pressure, and expand and bulge in the wider recessed portion, so that the gap of the cleaning strip is larger, thereby facilitating the flushing of impurities inside it. At the same time, when the flushing of the cleaning strip is completed, the cleaning strip will be squeezed in the middle of the funnel-shaped portion during the resetting process, thereby achieving the effect of "wringing out water" on itself, so that the dirty water and impurities inside can be more fully separated, and it is also convenient for the drying and subsequent use of the cleaning strip.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The voice curtain provided by the present invention sets the shape of the elastic strip so that the free end of the elastic strip can be easily deflected downward and is difficult to tilt upward, that is, when the curtain body moves downward from the elastic strip, the free end of the elastic strip has a smaller force on the curtain body, thereby reducing the resistance generated by the cleaning component to the release of the curtain body, and when the curtain body moves upward between the two elastic strips, the end of the elastic strip will exert a larger reverse force on the curtain body, so that the cleaning strip can be used to scrape and clean the surface of the curtain body more effectively, that is, the different movement directions of the curtain body can be used to adjust the force between the cleaning component and the curtain body, thereby improving the practical effect of the curtain.

[0016] 2. The present invention provides a voice curtain. When the curtain body is fully released, if it is necessary to adjust the shielding area of ​​the curtain body, the movement of the push rod inside the rotating rod is adjusted, and then the electromagnet is controlled to attract the sliding sleeve. Then, the sliding of the push rod inside the curtain body is adjusted, so that the electromagnet drives the curtain body on the sliding sleeve to move toward one end, thereby pulling the curtain body and adjusting the shielding area.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] See also Figure 1-Figure 6As shown, a voice curtain described in an embodiment of the present invention includes a storage box 1; a motor 2 is installed at one end inside the storage box 1, and a rotating rod 3 is connected to the output end of the motor 2, and a curtain body 4 is wound on the rotating rod 3. A retracting opening 5 is arranged on the bottom surface of the storage box 1, and the free end of the curtain body 4 passes through the retracting opening 5 and is connected to a counterweight 6. The motor 2 is electrically connected to a central processing unit through an electric control module, and the central processing unit signal is connected to a voice acquisition module. A plurality of groups of elastic strips 7 are symmetrically arranged at the side walls of the retracting opening 5 on both sides of the curtain body 4. The elastic strips 7 are arc-shaped and their free ends are bent downward. The cross-sectional width on the vertical plane 7 gradually increases from the free end to the connecting end, and a cleaning strip 8 capable of scraping the surface of the curtain body 4 is connected to the top surface of the free end of the elastic strip 7; when the voice curtain in the prior art is in use, although the cleaning brush arranged at the opening at the bottom end of the installation box can clean the sliding surface of the curtain body 4, when the extrusion force between the cleaning brush and the curtain body 4 is too small, it will affect the cleaning effect of the cleaning brush on the impurities on the surface of the curtain body 4, and when the adhesion force between the cleaning brush and the curtain body 4 is too large, it will produce a large resistance to the release of the curtain body 4, and the weight of the counterweight block 6 needs to be increased, but this will also increase the power of the motor 2; and the present invention When the voice curtain is in use, the voice collection module can be placed in a convenient position. When the curtain needs to work, the signal is transmitted to the central processor through voice, and the motor 2 is controlled to work through the electronic control module, so that the motor 2 releases the rolled-up curtain body 4 by driving the rotation of the rotating rod 3, thereby making the use of the curtain more intelligent and convenient. When the curtain body 4 is not needed to work, the curtain body 4 can be rolled up by reversing the motor 2 (which can be set as a servo motor). In this process, the cleaning strip 8 at the end of the elastic strip 7 can fit tightly with the surface of the curtain body 4, and the cleaning strip 8 can be used to clean the dust and impurities on the surface of the curtain body 4. By setting the shape of the elastic strip 7, the free end of the elastic strip 7 can be easily deflected downward and is difficult to tilt upward, that is, when the curtain body 4 moves downward from the elastic strip 7, the free end of the elastic strip 7 has a smaller force on the curtain body 4, thereby reducing the resistance generated by the cleaning component to the release of the curtain body 4. When the curtain body 4 moves upward between the two elastic strips 7, the end of the elastic strip 7 will exert a larger reverse force on the curtain body 4, so that the cleaning strip 8 can be used to scrape and clean the surface of the curtain body 4 more effectively, that is, the different movement directions of the curtain body 4 can be used to adjust the force between the cleaning component and the curtain body 4, thereby improving the practical effect of the curtain.

[0031] The connecting end of the elastic strip 7 is rotatably connected to the side wall of the receiving opening 5 by a torsion spring, and a limiting strip 9 is connected to the side wall of the receiving opening 5 at the top of the elastic strip 7; the elastic strip 7 is rotatably connected to the receiving opening 5 by the torsion spring, so that the free end of the elastic strip 7 can be rotated downward more easily, thereby reducing the resistance of the elastic strip 7 encountered by the curtain body 4 when it is lowered, and at the same time, when the curtain body 4 slides upward, the curtain body 4 can drive the free end of the elastic strip 7 to swing upward, and at the same time, the limiting strip 9 can resist the elastic strip 7 and limit it, so that the elastic strip 7 can apply a larger extrusion force to the curtain body 4, thereby improving the cleaning effect of the surface of the curtain body 4.

[0032] Under the action of its own gravity and the torsion spring, there is a gap between the free end of the elastic strip 7 and the curtain body 4. A first magnetic block 10 is arranged on the elastic strip 7. When the curtain body 4 is in a released state, an adsorption strip 11 is connected to the position of the top surface of the curtain body 4 corresponding to the elastic strip 7, and an adsorption block 12 is connected to the free end of the limiting strip 9. The first magnetic block 10 can be attracted to the adsorption strip 11 and the adsorption block 12 respectively. When the elastic strip 7 is in a natural state, there is a gap between its free end and the curtain body 4. At this time, the curtain body 4 will not be resisted by the elastic strip 7 when it is lowered, which further improves It ensures the smoothness of the curtain body 4 when it is released, and is also beneficial to the heat dissipation of the motor 2 inside the storage box. At the same time, when the curtain body 4 begins to roll up, the adsorption strip 11 set at its top moves to the elastic strip 7, and can attract the first magnetic block 10, and drive the free end of the elastic strip 7 to swing upward until the first magnetic block 10 of the elastic strip 7 moves to the position of the adsorption block 12 and adsorbs and fits with it. At this time, the elastic strip 7 can fit tightly with the curtain body 4 under the action of the first magnetic block 10 and the adsorption block 12, as well as the friction force of the curtain body 4, thereby having a cleaning effect on the surface of the curtain body 4.

[0033] An arc groove is provided on the side wall of the elastic strip 7 at the top of the cleaning strip 8, and a rolling column 13 of a matching shape is rotatably connected inside the arc groove, and the side wall of the rolling column 13 can fit the surface of the curtain body 4, and a group of annularly evenly distributed second magnetic blocks 14 are inlaid and installed on the side wall of the rolling column 13, and a cavity 15 is provided inside the elastic strip 7 corresponding to the bottom end of the arc groove, and an elastic film 16 is connected to the end of the cavity 15 close to the rolling column 13, and an elastic member 17 is connected between the elastic film 16 and the end of the cavity 15 away from the rolling column 13, and a magnetic member 18 that can interact with the second magnetic block 14 is connected to the surface of the elastic film 16, and the elastic strip 7 A nozzle 19 connected to the cavity 15 is provided on the bottom surface of the free end, and the jet direction of the nozzle 19 is toward the side of the curtain body 4; when the curtain body 4 slides upward, the friction force on the fitted rolling column 13 can drive the rolling column 13 to rotate continuously, so that the rolling column 13 drives the second magnetic block 14 on the surface to continuously pass through the magnetic member 18, so that the attraction between the two can drive the elastic membrane 16 to agitate in the cavity 15 after intermittent changes, so that the gas inside it can be sprayed onto the surface of the curtain body 4 through the nozzle 19, so that the impurities on the surface of the curtain body 4 can be blown off and pre-cleaned before being cleaned by the cleaning strip 8, thereby improving the cleaning quality of the surface of the curtain body 4.

[0034] A push rod 20 is installed at the side wall position of the storage box 1 opposite to the motor 2. The rotating rod 3 is a hollow tube. The telescopic rod of the push rod 20 extends to the inside of the rotating rod 3 and is connected to an electromagnet 21. A plurality of groups of sliding sleeves 22 are slidably connected to the outer wall of the rotating rod 3, and an elastic bellows 23 is connected between two adjacent sliding sleeves 22. The electromagnet 21 can attract the sliding sleeve 22 when working, and the connecting end of the curtain body 4 is fixedly connected to the side wall of the sliding sleeve 22; when the curtain body 4 is completely released, if it is necessary to adjust the shielding area of ​​the curtain body 4, at this time, by adjusting the movement of the push rod 20 inside the rotating rod 3, and then by controlling the operation of the electromagnet 21, it attracts the sliding sleeve 22, and then by adjusting the sliding of the push rod 20 inside the curtain body 4, the electromagnet 21 drives the curtain body 4 on the sliding sleeve 22 to move toward one end, thereby being able to pull the curtain body 4 and adjust the shielding area.

[0035] An arc-shaped slot 24 is provided at the top surface position of the counterweight block 6 corresponding to the elastic strip 7, and the shape of the slot 24 matches the shape of the elastic strip 7; when the curtain body 4 is fully rolled up, the slot 24 at the counterweight block 6 can engage with the elastic strip 7 under the pulling of the curtain body 4, thereby sealing the gap between the counterweight block 6 and the storage box, further reducing the dust accumulation and pollution inside the storage box.

[0036] Embodiment 2:

[0037] like Figure 7-Figure 8As shown, in contrast to Example 1, another embodiment of the present invention is as follows: the cleaning strip 8 is made of sponge material, a water pump 25 capable of communicating with an external water source is installed inside the counterweight block 6, a conducting groove 26 connecting the water pump 25 and the card slot 24 is provided inside the counterweight block 6, a flushing groove 27 is provided inside the elastic strip 7, and when the elastic strip 7 cooperates with the card slot 24, the flushing groove 27 can communicate the conducting groove 26 with the side wall of the elastic strip 7 at the cleaning strip 8, and a conductive groove 26 is provided at one side of the cleaning strip 8 to communicate with the card slot 24. The drainage groove 28 is connected to the outside world; when the sponge cleaning strip 8 cleans the surface of the curtain body 4 for a long time, a large amount of dust and impurities are accumulated on its surface and inside. If it is not effectively cleaned, the subsequent cleaning effect of the curtain body 4 will be affected. At this time, it is only necessary to connect the water pump 25 to the external water source, so that the water pump 25 pumps clean water into the cleaning strip 8 through the conducting groove 26 and the flushing groove 27, so that the dust and impurities accumulated at the cleaning strip 8 can be washed down through the drainage groove 28, thereby improving the subsequent cleaning quality of the curtain body 4 by the cleaning strip 8.

[0038] The water inlet end of the drainage groove 28 is provided with a funnel-shaped portion 29 which is wide in the middle and narrow at both ends, and the inner end of the funnel-shaped portion 29 is provided with a recessed portion 30; when the water flow impacts the cleaning strip 8, the cleaning strip 8 will pass through the narrower funnel-shaped portion 29 under the action of the water pressure, and expand and bulge in the wider recessed portion 30, so that the gap of the cleaning strip 8 is larger, thereby facilitating the flushing of impurities inside it. At the same time, when the flushing of the cleaning strip 8 is completed, the cleaning strip 8 will be squeezed in the middle of the funnel-shaped portion 29 during the resetting process, thereby achieving the effect of "wringing out water" for itself, so that the dirty water and impurities inside can be more fully separated, and it is also convenient for the drying and subsequent use of the cleaning strip 8.

[0039] Working principle: When the voice curtain of the present invention is in use, the voice collection module can be placed in a convenient position. When the curtain needs to work, the signal is transmitted to the central processor through voice, and the motor 2 is controlled to work through the electronic control module, so that the motor 2 drives the rotation of the rotating rod 3 to release the rolled-up curtain body 4, thereby making the use of the curtain more intelligent and convenient. When the curtain body 4 is not needed to work, the curtain body 4 can be rolled up by reversing the motor 2 (which can be set as a servo motor). In this process, the cleaning strip 8 at the end of the elastic strip 7 can fit tightly with the surface of the curtain body 4, and the cleaning strip 8 can be used to clean the surface of the curtain body 4. Dust and impurities are cleaned by setting the shape of the elastic strip 7 so that the free end of the elastic strip 7 can be easily deflected downward and is difficult to tilt upward, that is, when the curtain body 4 moves downward from the elastic strip 7, the free end of the elastic strip 7 has a smaller force on the curtain body 4, reducing the resistance of the cleaning component to the release of the curtain body 4, and when the curtain body 4 moves upward between the two elastic strips 7, the end of the elastic strip 7 will exert a larger reverse force on the curtain body 4, so that the cleaning strip 8 can be used to scrape and clean the surface of the curtain body 4 more effectively, that is, the different movement directions of the curtain body 4 can be used to adjust the force between the cleaning component and the curtain body 4, so that The practical effect of the curtain is improved; the elastic strip 7 is rotatably connected to the receiving opening 5 by the torsion spring, so that the free end of the elastic strip 7 can be rotated downward more easily, thereby reducing the resistance of the elastic strip 7 to the curtain body 4 when it is lowered, and at the same time, when the curtain body 4 slides upward, the curtain body 4 can drive the free end of the elastic strip 7 to swing upward, and at the same time, the limiting strip 9 can resist the elastic strip 7 and limit it, so that the elastic strip 7 can apply a large squeezing force to the curtain body 4, thereby improving the cleaning effect of the surface of the curtain body 4; when the elastic strip 7 is in a natural state, there is a gap between its free end and the curtain body 4, and at this time, the curtain body 4 will not be affected by the elastic strip when it is lowered. The resistance of the elastic strip 7 further improves the smoothness of the curtain body 4 when it is released, and is also beneficial to the heat dissipation of the motor 2 inside the storage box. At the same time, when the curtain body 4 begins to roll up, the adsorption strip 11 set at its top moves to the elastic strip 7, and can attract the first magnetic block 10, and drive the free end of the elastic strip 7 to swing upward, until the first magnetic block 10 of the elastic strip 7 moves to the position of the adsorption block 12 and adsorbs and fits with it. At this time, the elastic strip 7 can fit closely with the curtain body 4 under the action of the first magnetic block 10 and the adsorption block 12, and the friction of the curtain body 4, so that the surface of the curtain body 4 can be cleaned;When the curtain body 4 slides upward, the friction force on the rolling column 13 can drive the rolling column 13 to rotate continuously, so that the rolling column 13 drives the second magnetic block 14 on the surface to continuously pass through the magnetic member 18, so that the attraction between the two can drive the elastic membrane 16 to agitate in the cavity 15 after intermittent changes, so that the gas inside it can be sprayed on the surface of the curtain body 4 through the nozzle 19, so that the impurities on the surface of the curtain body 4 can be blown off and pre-cleaned before being cleaned by the cleaning strip 8, thereby improving the cleaning quality of the surface of the curtain body 4 ; When the curtain body 4 is fully released, if the shielding area of ​​the curtain body 4 needs to be adjusted, the movement of the push rod 20 inside the rotating rod 3 is adjusted, and then the electromagnet 21 is controlled to work so that it attracts the sliding sleeve 22, and then the sliding of the push rod 20 inside the curtain body 4 is adjusted, so that the electromagnet 21 drives the curtain body 4 on the sliding sleeve 22 to move toward one end, thereby pulling the curtain body 4 and adjusting the shielding area; when the curtain body 4 is fully rolled up, the slot 24 at the counterweight block 6 can be engaged with the elastic strip 7 under the pulling of the curtain body 4, so that it can The gap between the counterweight block 6 and the storage box is blocked to further reduce the dust accumulation and pollution inside the storage box; after the sponge cleaning strip 8 cleans the surface of the curtain body 4 for a long time, a large amount of dust and impurities are accumulated on the surface and inside. If it is not effectively cleaned, it will affect the subsequent cleaning effect of the curtain body 4. At this time, it is only necessary to connect the water pump 25 to the external water source so that the water pump 25 pumps clean water into the cleaning strip 8 through the conduction groove 26 and the flushing groove 27, so that the dust and impurities accumulated at the cleaning strip 8 can be washed down through the drainage groove 28. The subsequent cleaning quality of the curtain body 4 by the cleaning strip 8 is improved; when the water flow impacts the cleaning strip 8, the cleaning strip 8 will pass through the narrow funnel-shaped portion 29 under the action of the water pressure, and expand and bulge in the wider recessed portion 30, so that the gap of the cleaning strip 8 is larger, so that it is convenient for the impurities inside to be flushed out. At the same time, when the cleaning strip 8 is flushed, the cleaning strip 8 will be squeezed in the middle of the funnel-shaped portion 29 during the reset process, so as to achieve the effect of "wringing water" on itself, so that the internal dirty water and impurities are more fully separated, and it is also convenient for the cleaning strip 8 to be dried and used later. ;
