Detailed implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Refer to Figures 1 - 4 , the filter screen box body 2 is installed on the air inlet of the energy-saving air conditioner indoor unit main body 1. A fixing frame 3 is fixedly installed on the top of the filter screen box body 2. An air cylinder assembly 31 is swingably installed above the fixing frame 3. The piston rod of the air cylinder assembly 31 is connected to the driving rocker 32 through a rotating connector. In this way, the driving rocker 32 can be driven to swing by the air cylinder assembly 31, and then the driven rocker 33 and the lower swing arm 34 can be driven to swing synchronously. Since bristles are provided on the driving rocker 32, the driven rocker 33 and the lower swing arm 34, the dust on the surface of the filter screen box body 2 can be brushed off through the swinging of the driving rocker 32, the driven rocker 33 and the lower swing arm 34. It should be noted that the specific transmission connection structure for driving the dust sweeping assembly by the air cylinder assembly 31 is prior art, which has been widely publicly used in the mechanical transmission manual and does not belong to the main technical problems to be solved in this technical solution, so it will not be elaborated here.

[0020] Refer to Figures 5 - 7 , the filter screen box body 2 is sequentially provided with a stainless steel filter screen 21, a primary filter cotton 22 and a medium-effect filter cotton 23 from outside to inside, and the fixed air chamber 4 and the fixing plate 5 are both fixedly installed on the stainless steel filter screen 21. It should be noted that baffles are provided on the stainless steel filter screen 21 corresponding to the fixed air chamber 4 and the fixing plate 5, which can reduce the air flow passing through the vicinity of the fixed air chamber 4 and the fixing plate 5.

[0021] Refer to Figures 3 - 4 Figures 8 - 10. A clamping bracket 311 is fixedly arranged on the piston rod of the cylinder assembly 31, and a vertical rod 61 is clamped between the clamping brackets 311. In this way, the pushing and retracting of the piston rod can drive the clamping brackets 311 and the vertical rod 61 to move synchronously, and thus the cross rod 6 can be indirectly driven to move by the movement of the piston rod.

[0022] It should be noted that when the cylinder assembly 31 drives the dust sweeping assembly, during the pushing or retracting of its piston rod, there is not only vertical movement but also a certain vertical angular swing. Therefore, the clamping brackets 311 and the vertical rod 61 are not fixedly connected and there is a certain gap, and the clamping brackets 311 are only located on both sides of the vertical rod 61. This enables the clamping brackets 311 to still push the vertical rod 61 to move horizontally even during the reciprocating movement obliquely upward, without changing the moving angles of the cross rod 6 and the vertical rod 61, thus ensuring the stability of the cross rod 6 and the vertical rod 61 during movement.

[0023] A plurality of push rods 62 are fixedly arranged at the bottom of the cross rod 6. The push rods 62 are all fixedly connected to the movable plate 53 by bolts, and the movable plate 53 is guided to move through the horizontal guide posts 52. In this way, the movable plate 53 can be driven to move by the pushing of the push rods 62, and by guiding the movable plate 53 through the horizontal guide posts 52, the cross rod 6 can also be indirectly guided to improve the stability of the cross rod 6 during movement. In this way, during the reciprocating movement of the piston rod of the cylinder assembly 31, the movable plate 53 can be indirectly driven to perform reciprocating movement synchronously.

[0024] Refer to Figures 10 - 14 Figures 25. Two fixed seats 51 are fixedly arranged on the fixed plate 5. A one - way air valve 56 is fixedly arranged on the fixed seat 51 close to the adjustment cavity 43. The other end of the one - way air valve 56 is communicated with the adjustment cavity 43. On the other side of this side's fixed seat 51, an elastic corrugated pipe 55 communicated with the one - way air valve 56 is fixedly installed, and the other end of the elastic corrugated pipe 55 is fixedly connected to the air compression plate 54. A plurality of air inlets 541 are formed on the air compression plate 54, and sealing protrusions 531 are correspondingly and adaptively arranged on the movable plate 53 corresponding to the air inlets 541, and both the movable plate 53 and the air compression plate 54 are made of magnetically - attracted and adapted magnetic materials.

[0025] A plurality of horizontal guide posts 52 are fixedly connected between the two fixed seats 51. Both the movable plate 53 and the air compression plate 54 are guided to move through the horizontal guide posts 52. The movable plate 53 and the air compression plate 54 are made of magnetically - attracted and adapted magnetic materials. A plurality of stop members 58 are fixedly arranged on the fixed seat 51 close to the movable plate 53, and concave cavities 532 are correspondingly and adaptively formed on the movable plate 53 corresponding to the stop members 58.

[0026] During the process of the movable plate 53 moving towards the air compression plate 54, the sealing bumps 531 on the movable plate 53 are all adaptively inserted into the air inlet 541 on the air compression plate 54, thereby achieving the sealing of the elastic corrugated pipe 55. Subsequently, the movable plate 53 continues to move, thereby compressing the elastic corrugated pipe 55, and thus the air inside the elastic corrugated pipe 55 can be extruded into the adjustment cavity 43 through the one-way air valve 56.

[0027] During the process of the movable plate 53 resetting, the movable plate 53 adsorbs the air compression plate 54 and retracts synchronously through magnetic attraction. When the air compression plate 54 touches the stopper 58, since the concave cavity 532 is provided on the movable plate 53, the movable plate 53 can continue to move and reset, while the air compression plate 54 cannot continue to move due to the blocking of the stopper 58. In this way, the movable plate 53 and the air compression plate 54 adsorbed together through magnetic attraction can be separated. At this time, the sealing bump 531 on the movable plate 53 is no longer located in the air inlet 541, and air can reflow into the elastic corrugated pipe 55 through the air inlet 541. To ensure that the gas in the elastic corrugated pipe 55 is full, so that the movable plate 53 can still push the air in the elastic corrugated pipe 55 into the adjustment cavity 43 during the next movement.

[0028] Two bumps are provided on the side wall of the fixed seat 51, a guide rod is fixedly connected between the two bumps, and the pressure rod 57 can be guided to move through the guide rod. A first spring 511 is provided upward on the lower bump, the other end of the first spring 511 is connected to the pressure rod 57, and the first spring 511 is located outside the guide rod.

[0029] A magnetic member 571 is fixedly provided at the bottom of the pressure rod 57, and a magnet 533 that is adapted to attract the magnetic member 571 is fixedly provided on the movable plate 53. When the movable plate 53 moves outward, the elastic force of the first spring 511 can push the pressure rod 57 upward.

[0030] When the movable plate 53 retracts and resets, the magnet 533 moves above the magnetic member 571. At this time, through the magnetic attraction of the magnet 533 to the magnetic member 571, the pressure rod 57 can overcome the elastic force of the first spring 511 and move downward. At this time, the pressure rod 57 moves downward and the first spring 511 is compressed.

[0031] A pressing member 572 is adaptively provided at one end of the pressure rod 57 corresponding to the ejector rod 82, and the protruding ejector rod 82 can be pressed downward through the pressing member 572. A plurality of positioning rods 573 are fixedly provided below the pressing member 572, and positioning grooves 721 are adaptively provided on the ejector rod 82 corresponding to the positioning rods 573. In this way, through the adaptive setting between the positioning rods 573 and the positioning grooves 721, the stability of the pressing member 572 when pressing the ejector rod 82 downward can be improved.

[0032] Refer toFigures 15 - 18 、21. Align the fixed air chamber 4 with the driving rocker 32, the driven rocker 33, and the lower swing arm 34, and the swinging of the dust sweeping assembly will not interfere with the fixed air chamber 4 because the driving rocker 32, the driven rocker 33, and the lower swing arm 34 do not contact the fixed air chamber 4, and only the bristles on their outer sides contact the fixed air chamber 4. In this way, the dust on the bristles can be blown off by the gas ejected from the air outlet holes 411 on the fixed air chamber 4.

[0033] An air cavity 41 is formed inside the fixed air chamber 4, and the air outlet holes 411 are all formed on the air cavity 41. A inner plate 42 is vertically movably arranged in the air cavity 41, and through holes 421 are correspondingly formed on the inner plate 42 corresponding to the air outlet holes 411. When the inner plate 42 is located below, the air outlet holes 411 and the through holes 421 are alternately spaced in sequence. At this time, the inner plate 42 blocks the inner side of the air outlet holes 411, which makes the gas in the air cavity 41 unable to be ejected from the air outlet holes 411.

[0034] When the inner plate 42 moves upward, the air outlet holes 411 and the through holes 421 are aligned one by one. At this time, the gas in the air cavity 41 can be ejected from the air outlet holes 411. It should be noted that corresponding sliders and chutes are arranged on both the inner plate 42 and the air cavity 41, which can not only ensure the stability of the inner plate 42 during the vertical movement process, but also ensure the stable alignment between the air outlet holes 411 and the through holes 421 when the inner plate 42 moves to the uppermost position.

[0035] The tops of the inner plates 42 all extend into the adjustment cavity 43 and are fixedly provided with top members 422, and lever grooves 423 are formed on both sides of the bottom of the top members 422. Rotating shafts 45 are rotatably arranged on both sides inside the adjustment cavity 43, and levers 451 are correspondingly arranged on the rotating shafts 45 corresponding to the lever grooves 423.

[0036] By pressing down the outer sides of the two levers 451, the other ends of the two levers 451 can simultaneously lift the top member 422 upward. In this way, the inner plate 42 can be driven to move upward synchronously by the top member 422, so that the air outlet holes 411 and the through holes 421 can be aligned to realize the jetting of the air outlet holes 411. And through the setting of the lever grooves 423, the contact stability between the lever 451 and the top member 422 can be improved, so that the lever 451 can stably lift the top member 422.

[0037] Refer to Figures 19 - 25 , the top plate 44 is fixedly installed on the top of the adjustment cavity 43, side elastic pads 441 are arranged on both sides of the top plate 44, and a middle elastic pad 442 is arranged in the middle of the top plate 44. Through the setting of the side elastic pads 441 and the middle elastic pad 442, the sealing performance inside the air cavity 41 and the adjustment cavity 43 can be ensured, and the pressing block 7 outside the top plate 44 can enter the adjustment cavity 43.

[0038] A plurality of vertical guide columns 9 are fixedly arranged upward on the top of the top plate 44, and the pressing block 7 is guided and moved by the vertical guide columns 9. Second springs 91 are arranged upward on both sides of the vertical guide columns 9 on the top plate 44, and the other ends of the second springs 91 are connected to the pressing block 7. Guide members 83 are fixedly arranged on both sides of the support rod 81, and the guide members 83 are guided and moved by the vertical guide columns 9. By setting the vertical guide columns 9, the pressing block 7 and the thin plate 8 can be guided to improve the stability of the pressing block 7 and the thin plate 8 during the vertical movement.

[0039] When the pressing block 7 moves downward, the side elastic pad 441 is deformed downward, so that the pressing block 7 can press the outer end of the lever 451 downward through the side elastic pad 441, so that the top piece 422 can be tilted upward through the lever 451.

[0040] An extrusion seat 71 is fixedly provided at the bottom of the middle part of the pressing block 7, and an inclined sliding cavity 711 is provided at the bottom of the extrusion seat 71. An inclined sliding block 72 is movably provided in the inclined sliding cavity 711, and a positioning groove 721 is adapted to be provided at the end of the inclined sliding block 72 corresponding to the positioning rod 573.

[0041] A thin plate 8 is installed on the top of the middle elastic pad 442, and a support rod 81 is fixed upward on the top of the thin plate 8. A push rod 82 adapted to the inclined sliding block 72 is fixed on the top of the support rod 81, and a push rod cavity 712 is adapted to the push rod 82 on the extrusion seat 71.

[0042] The bottom of the inclined slide block 72 is an inclined surface and is adapted to the push rod 82. When the push rod 82 moves vertically upward, it can push the inclined slide block 72 obliquely upward, so that the inclined slide block 72 can be pushed out of the inclined slide cavity 711. In addition, a push rod cavity 712 is adapted to correspond to the push rod 82 on the extrusion seat 71. When the push rod 82 is fully extended into the push rod cavity 712, the inclined slide block 72 is fully pushed out of the inclined slide cavity 711. At this time, the pressing rod 57 can contact the inclined slide block 72 when moving downward, so that the inclined slide block 72, the pressing block 7 and the thin plate 8 can be synchronously pressed downward by the pressing rod 57.

[0043] It is worth noting that since the positioning rod 573 is fixed downwardly arranged on the pressing member 572, the positioning groove 721 is adapted to be opened on the corresponding positioning rod 573 on the inclined sliding block 72. This allows the vertical positioning rod 573 to be inserted into the positioning groove 721 when the pressing member 572 moves downward. This allows the inclined sliding block 72 to be unable to move obliquely downward through the oblique sliding cavity 711 through the adaptation and clamping between the positioning rod 573 and the positioning groove 721 during the pressing member 572 continues to move downward, thus ensuring that the pressing member 572 can synchronously press the pressing block 7 and the thin plate 8 downward through the oblique sliding block 72.

[0044] In this embodiment, through the arrangement of the stainless-steel filter screen 21, the primary filter cotton 22, and the medium-effect filter cotton 23 in the filter screen box body 2, the filtration of the gas entering the inner body 1 of the energy-saving air conditioner can be realized to protect the air-conditioning system and the indoor air quality. And through the drive of the cylinder assembly 31 on the dust-sweeping assembly, the dust and impurities on the surface of the stainless-steel filter screen 21 can be brushed off.

[0045] When the user needs to clean the surface of the stainless-steel filter screen 21, only need to control the piston rod of the cylinder assembly 31 to extend outwards, so that it drives the active rocker 32 to swing. In this way, the driven rocker 33 and the lower swing arm 34 can be driven to swing by the active rocker 32. When the piston rod retracts, the active rocker 32, the driven rocker 33, and the lower swing arm 34 reset. In this way, through the continuous swinging of the active rocker 32, the driven rocker 33, and the lower swing arm 34, the dust on the surface of the stainless-steel filter screen 21 can be brushed off by the bristles on their outer sides.

[0046] And when the piston rod of the cylinder assembly 31 extends outwards, it can drive the vertical rod 61 to move outwards through the clamping frame 311, so as to indirectly drive the cross rod 6, the push rod 62, and the movable plate 53 to move. It should be noted that since there is no fixation and there is a gap between the clamping frame 311 and the vertical rod 61, this makes the cross rod 6, the push rod 62, and the movable plate 53 only move horizontally without any change in the vertical angle.

[0047] During the process of the movable plate 53 moving towards the air compression plate 54, the sealing bumps 531 on the movable plate 53 are all adaptively inserted into the air inlet 541 on the air compression plate 54, so as to realize the sealing of the elastic corrugated pipe 55. Then the movable plate 53 continues to move, so as to compress the elastic corrugated pipe 55, and thus the air in the elastic corrugated pipe 55 can be extruded into the adjustment cavity 43 through the one-way air valve 56.

[0048] When the piston rod of the cylinder assembly 31 retracts inwards, it can also drive the vertical rod 61, the cross rod 6, the push rod 62, and the movable plate 53 to move and reset through the clamping frame 311. During the process of the movable plate 53 retracting and resetting, the movable plate 53 adsorbs the air compression plate 54 to retract synchronously through magnetic attraction, and the compressed elastic corrugated pipe 55 gradually expands. When the air compression plate 54 touches the stopper 58, since the concave cavity 532 is provided on the movable plate 53, the movable plate 53 can continue to move and reset, while the air compression plate 54 cannot continue to move due to the blocking of the stopper 58.

[0049] In this way, the movable plate 53 and the air pressure plate 54, which are attracted together by magnetic attraction, can be separated. At this time, the sealing protrusion 531 on the movable plate 53 is no longer located in the air inlet 541, and the air can flow back into the elastic bellows 55 through the air inlet 541. This ensures that the gas in the elastic bellows 55 is filled, so that the movable plate 53 can still push the air in the elastic bellows 55 into the adjustment chamber 43 when it moves next time.

[0050] In this way, the movable plate 53 can be driven to move back and forth by the continuous extension and retraction of the piston rod of the cylinder assembly 31 , so as to continuously inflate the air cavity 41 and the regulating cavity 43 , thereby continuously increasing the pressure in the air cavity 41 and the regulating cavity 43 .

[0051] Furthermore, when the pressure inside the air cavity 41 and the regulating cavity 43 gradually increases, the middle elastic pad 442 can be deformed upward by the air pressure. In this way, the thin plate 8, the support rod 81 and the push rod 82 can be pushed upward by the middle elastic pad 442, so that the inclined sliding block 72 can be pushed outward by the vertical movement of the push rod 82. When the air pressure inside the air cavity 41 and the regulating cavity 43 is high enough, when the push rod 82 completely moves upward into the push rod cavity 712, it also completely pushes the inclined sliding block 72 out of the inclined sliding cavity 711. In this way, the inclined sliding block 72 can adjust its position according to the change of air pressure in the air cavity 41.

[0052] Furthermore, when the movable plate 53 moves toward the adjustment chamber 43, the pressure rod 57 can be pushed upward by the elastic force of the first spring 511. When the movable plate 53 is retracted and reset, the magnet 533 moves above the magnetic member 571. At this time, the magnetic attraction of the magnet 533 to the magnetic member 571 enables the pressure rod 57 to overcome the elastic force of the first spring 511 and move downward. At this time, the pressure rod 57 moves downward and the first spring 511 is compressed.

[0053] When the inclined slide block 72 is completely pushed out of the inclined slide cavity 711, the movable plate 53 controls the pressing rod 57 to move downward through the magnetic attraction of the magnet 533 to the magnetic member 571. At this time, during the downward movement of the pressing rod 57, the positioning rod 573 on the pressing member 572 can be automatically inserted into the positioning groove 721 on the inclined slide block 72, so that the inclined slide block 72 can be driven by the pressing rod 57 to move vertically downward, thereby driving the pressing block 7 and the thin plate 8 to move downward synchronously.

[0054] When the pressing block 7 moves downward, the side elastic pad 441 is deformed downward, so that the pressing block 7 can press the outer end of the lever 451 downward through the side elastic pad 441, so that the top piece 422 can be tilted upward through the lever 451.

[0055] Thus, the inner plate 42 can be driven to move upward synchronously by the top member 422, so that the through hole 421 on the inner plate 42 is aligned with the air outlet hole 411 in the air cavity 41. At this time, the gas in the air cavity 41 can be ejected through the air outlet hole 411, so that the dust on the bristles on the surfaces of the active rocker 32, the slave rocker 33 and the lower swing arm 34 can be blown away by the ejected gas.

[0056] Furthermore, after the gas in the air cavity 41 is ejected, the air pressure in the air cavity 41 is the same as that outside. In this way, when the pressure rod 57 moves upward next time, the pressure block 7 can be automatically reset by the elastic force of the second spring 91. The middle elastic pad 442 is no longer deformed upward due to the air pressure, and the thin plate 8, the support rod 81 and the push rod 82 are also automatically reset. The inclined slide block 72 is no longer squeezed by the push rod 82, and can also automatically fall to the bottom of the inclined slide cavity 711 by gravity.

[0057] And because the pressing block 7 no longer presses one end of the lever 451, the inner plate 42 and the top piece 422 can automatically fall down by gravity, and the through hole 421 and the air outlet 411 are misaligned again, and the air outlet 411 is blocked again. In this way, all components can be automatically reset, so that the bristles can be blown back by the reciprocating movement of the movable plate 53 next time.

[0058] Furthermore, the user can set a cleaning time interval in the system of the energy-saving air conditioner indoor unit body 1, so that the energy-saving air conditioner indoor unit body 1 automatically stops for cleaning after running for a period of time.

[0059] During the cleaning process, the cleaning assembly is first driven by the cylinder assembly 31 to swing back and forth to brush the dust, and the cylinder assembly 31 drives the cleaning assembly to work, which can indirectly drive the movable plate 53 to reciprocate. In this way, the air cavity 41 can be continuously inflated during the process of the movable plate 53 squeezing the air pressure plate 54 and the elastic bellows 55, so as to continuously increase the air pressure inside the air cavity 41.

[0060] During the process of increasing the air pressure inside the air cavity 41, the middle elastic pad 442 can be deformed to drive the push rod 82 to push the inclined slider 72. When the air pressure inside the air cavity 41 is sufficient, the deformation of the middle elastic pad 442 pushes the push rod 82 completely into the push rod cavity 712, and the inclined slider 72 is completely pushed out. At this time, the inclined slider 72 can be pushed vertically downward by the reciprocating pressure rod 57 to drive the pressing block 7 and the thin plate 8 to move downward synchronously, so that the pressing block 7 can press one end of the outer side of the lever 451 downward across the side elastic pad 441, so that the top piece 422 and the inner plate 42 can be tilted upward by the lever 451. At this time, the air outlet 411 is opened, and the gas in the air cavity 41 can be ejected through the air outlet 411 to realize the backblowing of the bristles, and a cleaning cycle is realized at this time.

[0061] It should be noted that when the air pressure inside the air chamber 41 does not reach the specified level, the deformation generated by the medium elastic pad 442 is not sufficient to completely push the ejector rod 82 into the ejector rod chamber 712. At this time, the inclined slider 72 cannot be completely ejected. Therefore, the reciprocating pressure rod 57 does not contact the inclined slider 72, and it cannot press the inclined slider 72 vertically downward.

[0062] In the present invention, the filter screen box body 2 can be used to filter the gas entering the energy-saving air conditioner indoor unit body 1. By driving the dust sweeping component by the cylinder component 31, the dust on the surface of the filter screen box body 2 can be brushed off. And during the process of the cylinder component 31 driving the dust sweeping component, the movable plate 53 can be indirectly driven to reciprocate to realize the inflation inside the air chamber 41. And through the matching setting among the medium elastic pad 442, the ejector rod 82, the inclined slider 72, the pressure rod 57, the pressure block 7 and the inner plate 42, when the air pressure inside the air chamber 41 is sufficient, the air outlet hole 411 can be automatically opened to realize the back blowing of the bristles. This cleaning method for the dust on the surface of the filter screen box body 2 does not require manual operation and is convenient for users to use.

[0063] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
