Description

Technical Field

[0001] The present invention relates to the technical field of dustproof cleaning, and in particular to a dustproof cleaning device and method for an oblique chain type automatic window opener. Background Art

[0002] The chain window opener drives the opening and closing of the window sash through a chain system. The electric chain window opener usually has a motor as a power source, which drives the chain to roll to open or close the window. Since the chain is exposed to the air when the window is open, dust will accumulate. In order to prevent dust from entering the window opener, the dust on the chain needs to be cleaned when the chain is recovered.

[0003] The existing window opener does not have a structure for cleaning the chain, so it is necessary to manually clean the dust on the chain regularly, which cannot achieve a good cleaning effect. Therefore, publication number CN212576931U discloses a dust prevention and dust removal device for a window opener, which includes a main shell and a mounting frame arranged on both sides of the outer surface of the main shell, and a clamping plate arranged at the front end of the main shell, the outer surface of the mounting frame is provided with a movable screw, the upper end outer surface of the mounting frame is provided with a fixing screw, the outer surface of the main shell is provided with a mounting hole at the position of the mounting frame, the front end of the main shell is connected with a cleaning frame at the position of the clamping plate, a chain rod is connected between the cleaning frame and the clamping plate, the front end of the main shell is provided with an opening at the position of the cleaning frame, and cards are fixedly installed on both sides of the inner wall of the opening.

[0004] A cleaning rack is installed in the opening on the main body shell of the dust-proof and dust-removing device of the above-mentioned window opener through the cooperation of the bracket and the sliding rod. Therefore, when the chain rod moves in the cleaning rack, the outer surface of the chain rod can contact the cleaning brush in the cleaning rack. At this time, the cleaning brush can sweep off the dust accumulated on the chain rod, and then the chain rod can be effectively kept clean to prevent dust accumulation from affecting the effect of later use.

[0005] However, when the dust-proof and dust-removing device of the above-mentioned window opener is used, dust is adhered to the brush to clean the dust, resulting in incomplete cleaning. At the same time, the brush cleaning method is single and cannot clean every corner of the chain, resulting in poor cleaning effect, and dust still enters the window opener.

[0006] Therefore, a novel dust-proof cleaning device and method for an inclined chain automatic window opener can be used to solve the deficiencies of the prior art. Summary of the invention

[0020] The present invention also provides a dustproof cleaning method for an oblique chain type automatic window opener, comprising the above-mentioned dustproof cleaning device for an oblique chain type automatic window opener, and further comprising the following steps:

[0021] S1. First, install the cleaning part, and drive the purge assembly to rotate around the air box through the driving module. Since the air box adopts an open design, the driving module is placed on the machine body and fixed, and then the air box is put on the chain;

[0022] S2, when the window opener is opened, the sensor will not respond, and the cleaning unit remains stationary. Once the chain on the window opener is retracted, the sensor will sense the chain retraction and send a signal to the drive module to operate.

[0023] S3, the operation of the driving module will drive the gas injection component to operate, and the gas is injected into the gas box through the gas injection component, and then the gas is injected into the purge component through the gas box, and the dust on the chain is blown away by the purge component. At the same time, the driving module will also drive the purge component to reciprocate around the gas box within a certain angle to purge the chain in multiple directions;

[0024] S4. As the chain is recycled, after being blown by the blowing component, the chain will be cleaned by the cleaning component to clean the dust adhering to the chain again.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] 1. When cleaning the window opener chain, the dust-proof cleaning device of the window opener is equipped with a pulse jet head to blow away the dust on the chain. During the blowing and washing process, the pulse gas ejected by the pulse jet head will impact the chain, thereby improving the cleaning efficiency of the chain. In addition, the pulse jet head can also rotate within a certain range to achieve multi-directional blowing and washing, making the cleaning more thorough and more efficient.

[0027] 2. When cleaning the chain of the window opener, the dust-proof cleaning device of the window opener further cleans the chain after washing by setting a brush. The position of the brush is changed with the use of the adjustment mechanism to ensure that the brush and the chain are against each other. It is suitable for cleaning different types of chains, making the chain cleaning more thorough.

[0028] 3. When the dust-proof cleaning device of the window opener is cleaning the chain of the window opener, since the brush adopts a hollow design, air can be injected into the brush through the air injection component to expand the brush and increase the pressure between the brush and the chain, so that it can be used to clean the chain of different opening lengths, and a nozzle is provided to clean the brush to keep the brush clean.

[0029] 4. When the dust-proof cleaning device of the window opener is cleaning the chain of the window opener, a tube collection assembly is provided to collect the air injection tube, and a lead mechanism is used to guide the air injection tube so that the air injection tube moves along the inner wall of the air box when extended. This prevents the suspension of the air injection tube from affecting the recovery of the connecting piece, thereby ensuring that the connecting piece can be extended or recovered smoothly.

[0030] To sum up, during chain cleaning, the present invention utilizes a pulse jet head to blow away the dust on the chain. Meanwhile, the pulse jet head can rotate within a certain range to blow away the chain in multiple directions. After blowing away, the dust remaining on the chain is cleaned with a brush. The cleaning efficiency is high. In addition, the dust adhering to the brush can also be cleaned, so that the chain cleaning is more thorough. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0050] Example 1: Reference Figure 1-Figure 2 , a dustproof cleaning device for an oblique chain type automatic window opener, comprising a window opener and a cleaning part;

[0051] The window opener consists of three parts: a body 1, a chain 5 and a connecting piece 2. A driving system is provided inside the body 1 for driving the chain 5 to move, and the chain 5 drives the connecting piece 2 to move to open and close the window. The basic main structure of the window opener is introduced here. Since this device is a dust-proof and cleaning device for the window opener, it has nothing to do with the internal mechanism of the window opener, and only cleans the chain 5 of the window opener. Therefore, the specific operation of the window opener and its internal structure are not elaborated here.

[0052] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 1 , Figure 3-Figure 16 , a cleaning part, used for cleaning dust on the chain 5, the cleaning part includes a driving module 3, a fixing frame 9 is fixedly mounted on the driving module 3, and a cleaning component 6 is mounted on the fixing frame 9 for cleaning dust on the chain 5;

[0053] The driving module 3 is a signal processing terminal, which can convert the sensing signal into an electrical signal and then operate the components inside the driving module 3. It is a common device currently available and will not be described in detail here.

[0054] The cleaning component 6 includes a hollow box 12, on which a plurality of nozzles 16 and a plurality of brushes 13 are fixedly mounted. Each brush 13 is hollow in design and is made of rubber material with a certain tension. The brush 13 is connected to the hollow box 12, and an adjustment mechanism is installed between the hollow box 12 and the fixed frame 9.

[0055] After the air in the hollow box 12 enters the brush 13 , the pressure inside the brush 13 increases, so the brush 13 expands. The expanded brush 13 has a greater hardness, and has a better cleaning effect on the dust adhering to the chain 5 .

[0056] The functions of the nozzle 16 are: first, to blow air vertically onto the chain 5 to remove the dust brushed off by the brush 13 and to further clean the chain 5; second, to blow air onto the brush 13 to clean the brush 13 and to drop the dust adhering to the brush 13 for cleaning the brush 13.

[0057] refer to Figure 4-Figure 6 The adjustment mechanism includes a hole opened on the fixing frame 9, a nut 11 is fixedly installed inside the hole, a screw 10 is threadedly installed on the nut 11, and the bottom of the screw 10 is rotatably connected to the hollow box 12;

[0058] The screw 10 is rotated, and the screw 10 moves on the nut 11 under the action of the nut 11, thereby driving the hollow box 12 to move. Since the hollow box 12 is not limited by external force when the screw 10 rotates, the screw 10 will drive the hollow box 12 to rotate. At this time, the hollow box 12 needs to be limited, and the following operation is adopted;

[0059] Two limit blocks 15 are fixedly mounted on the fixing frame 9, and a through hole is formed on each of the two limit blocks 15. Two sliding rods 14 cooperating with the limit blocks 15 are fixedly mounted on the hollow box 12, and the two sliding rods 14 slide in the corresponding through holes respectively.

[0060] Under the action of the limit block 15 and the sliding rod 14, the hollow box 12 can only slide in the through hole on the limit block 15 through the sliding rod 14, so the hollow box 12 can only move up and down, and the screw rod 10 is rotationally connected to the hollow box 12, so when the screw rod 10 rotates, it will not drive the hollow box 12 to rotate, but can only drive the hollow box 12 to move up and down, so as to realize the position adjustment of the hollow box 12.

[0061] The purpose of adjusting the hollow box 12 is to adjust the position of the brush 13. The contact force between the brush 13 and the surface of the chain 5 increases, and the friction force is also enhanced, which enables the brush 13 to more effectively remove dust on the surface of the chain 5. The enhanced friction force helps to clean more thoroughly.

[0062] In addition, by adjusting the position of the brush 13 so that the brush 13 presses against the chain 5, the brush 13 will bend or deform, so that the brush 13 can better fit the surface structure of the chain 5, especially the uneven or difficult-to-clean areas of the chain 5, so that the dust in the fine cracks on the surface can be more fully cleaned.

[0063] A sensor is fixedly installed at the bottom of the fixed frame 9 and is connected to the driving module 3. It is used to detect the movement of the chain 5 and send a signal to the driving module 3. When the window opener is opened, the sensor will not respond, and the cleaning part remains stationary. Once the chain 5 on the window opener is retracted, the sensor will sense the retraction of the chain 5 and send a signal to the driving module 3 to enable the driving module 3 to operate.

[0064] A magnetic plate is fixedly installed at the bottom of the driving module 3 for fixing the driving module 3 . The outer shell of the machine body 1 is made of steel, and the driving module 3 is adsorbed on the machine body 1 through the magnetic plate.

[0065] The fixing frame 9 is provided with a purge assembly 7 for blowing off dust on the chain 5. The purge assembly 7 includes an air box 4. The specific shape of the air box 4 is as follows: Figure 15-16 shown.

[0066] refer to Figure 3 , Figure 7-Figure 12 The purge assembly 7 also includes an incomplete gear ring 21 rotatably mounted on the air box 4. Two motors are arranged inside the drive module 3. A gear 20 matching the incomplete gear ring 21 is fixedly mounted on the driving ends of the two motors. An incomplete rotating circle 17 is slidably mounted on the inner wall of the air box 4. The incomplete rotating circle 17 is fixedly connected to the incomplete gear ring 21. The incomplete rotating circle 17 adopts a hollow design. A plurality of pulse jet heads 18 are fixedly mounted on the incomplete rotating circle 17. Each pulse jet head 18 is connected to the inside of the incomplete rotating circle 17. The incomplete rotating circle 17 is connected to the air box 4 through an air injection pipe 22. A pipe receiving assembly 19 matching the air injection pipe 22 is installed on the air box 4.

[0067] The bottom of the incomplete rotating circle 17 is designed with an opening, and the size of the opening is larger than the width of the chain 5 . The diameter of the air box 4 is larger than the length of the connecting piece 2 , ensuring that the connecting piece 2 can pass through the middle of the air box 4 .

[0068] The arc formed by the incomplete toothed ring 21 and the center point of the air box 4 exceeds 270 degrees, and the arc formed by the two gears 20 and the center point of the air box 4 is greater than 90 degrees. This ensures that there is always a gear 20 engaged with the incomplete toothed ring 21, so that the incomplete toothed ring 21 can rotate freely on the air box 4.

[0069] The direction and speed of the two motors are synchronized. The rotation of the motor driving end drives the gear 20 to rotate, thereby driving the incomplete gear ring 21 to rotate. The rotation of the incomplete gear ring 21 drives the incomplete rotating circle 17 fixedly connected to it to rotate, thereby driving the pulse jet head 18 to rotate, realizing multi-angle rotation and blowing.

[0070] The motor driving end reciprocates within a certain range. When one end of the incomplete rotating circle 17 rotates to a point close to the highest point of the air box 4 but does not reach the highest point, the motor driving end reverses. Therefore, the arrival trajectory of the incomplete rotating circle 17 is an incomplete ring with an upper opening.

[0071] The pulse jet head 18 acts on the surface through short and high-pressure air pulses, which can quickly and effectively remove attached dust, dirt or impurities. Compared with continuous airflow, the pulse jet has a stronger intensity and can better break up stubborn dirt. It is suitable for more complex or difficult to clean surfaces.

[0072] The tube collection assembly 19 includes a winding rack 25 fixedly mounted on the inner wall of the air box 4, a shaft body rotatably mounted on the winding rack 25, a toothed disc 26 fixedly mounted on the shaft body, a spring roll reset unit 27 matched with the toothed disc 26 fixedly mounted on the winding rack 25, an air injection pipe 22 is wound on the shaft body on the winding rack 25, one end of the air injection pipe 22 is connected with the incomplete rotating circle 17, and the other end passes through the central axis of the shaft body and is connected with the air box 4, and a lead mechanism matched with the air injection pipe 22 is installed on the inner wall of the air box 4.

[0073] As the incomplete rotating circle 17 rotates, the gas injection pipe 22 will move with the incomplete rotating circle 17, so the gas injection pipe 22 will drive the shaft body to rotate (when the gas injection pipe 22 is extended), thereby achieving the purpose of loosening the winding. When the gas injection pipe 22 is recovered, the spring winding reset unit 27 drives the toothed disc 26 to automatically reset, so that the gas injection pipe 22 is wound around the shaft body.

[0074] The spring roll reset unit 27 is a common automatic reset structure, which is composed of a spring roll and a gear shaft. The gear shaft is meshed with the toothed disc 26. The rotation of the shaft body will drive the gear shaft to rotate through the toothed disc 26, thereby winding the spring roll. The spring roll will store energy. Once the toothed disc 26 reverses or loses the thrust for forward rotation, the toothed disc 26 will be reset under the action of the spring roll.

[0075] The lead-in mechanism includes a sliding groove 36 provided on the inner wall of the gas box 4 , in which two sliding plates 23 are slidably mounted, and two magnets 24 matching the corresponding sliding plates 23 are fixedly mounted on the gas injection pipe 22 .

[0076] The purpose of this design is to limit the gas injection pipe 22 to prevent the gas injection pipe 22 from being suspended, and to ensure that the gas injection pipe 22 will not affect the connecting piece 2 when it moves. When the gas injection pipe 22 is extended, the magnet 24 will attract the sliding plate 23 to drive the sliding plate 23 to slide in the sliding groove 36, so that the gas injection pipe 22 is close to the inner wall of the gas box 4. When the gas injection pipe 22 is retracted, the gas box 4 will push the sliding plate 23 to slide in the sliding groove 36. When the sliding plate 23 located at the upper part reaches the top position, the gas injection pipe 22 continues to be recovered, and the magnet 24 will separate from the sliding plate 23. At this time, the gas injection pipe 22 will slide in the sliding plate 23 until the other magnet 24 reaches the position of the sliding plate 23. A magnetic blocking plate is installed between the other magnet 24 and the sliding plate 23 to prevent the other magnet 24 from being attracted to the sliding plate 23.

[0077] A gas injection assembly 8 is installed on the gas box 4 for injecting gas into the gas box 4 and injecting gas into the cleaning assembly 6 for cleaning dust on the cleaning assembly 6 .

[0078] refer to Figure 3 , Figure 13-14 The gas injection assembly 8 includes a frame 29 fixedly mounted on the gas box 4, a cylinder 30 fixedly mounted on the frame 29, and a camshaft 34 rotatably mounted on the frame 29 through a bearing 35, a push rod 33 rotatably mounted on the camshaft 34, and a one-way piston disk 32 matching the cylinder 30 rotatably mounted on the push rod 33, two one-way air outlet pipes fixedly mounted on the cylinder 30, one of which is connected to the hollow box 12, and the other is connected to the gas box 4, and a linkage mechanism is installed between the camshaft 34 and one of the gears 20.

[0079] The rotation of the camshaft 34 will drive the one-way piston disc 32 to move in the cylinder body 30 through the push rod 33 (the one-way piston disc 32 is a general term for the piston disc and the one-way air intake pipe, and the one-way air intake pipe is used to intake air into the cylinder body 30), and air will be injected into the cylinder body 30. Then, the air in the cylinder body 30 will be injected into the hollow box 12 and the air box 4 respectively through the one-way air outlet pipe, and the air will be injected into the incomplete rotating circle 17 through the air box 4 and the air injection pipe 22, and then sprayed out through the pulse jet head 18.

[0080] A part of the air injected into the hollow box 12 is ejected through the nozzle 16 , and the other part is filled into the brush 13 to change the hardness of the brush 13 .

[0081] The linkage mechanism includes an accelerator 31 fixedly mounted on the frame 29 , one end of the gear 20 and the accelerator 31 are connected via a universal flexible shaft 28 , and the other end of the accelerator 31 is fixedly connected.

[0082] The function of the accelerator 31 is to increase the rotation speed of the camshaft 34 so that the rotation speed of the camshaft 34 is greater than the rotation speed of the incomplete gear ring 21, so as to ensure sufficient jet volume. At the same time, the jet frequency and jet intensity can be changed by changing the acceleration degree of the accelerator 31. At the same time, the change in jet volume will also change the hardness of the brush 13, and the hardness of the brush 13 is controlled by the rotation speed.

[0083] The specific operation steps of this device are as follows:

[0084] S1. First, install the cleaning part, and drive the purge assembly 7 to rotate around the air box 4 through the driving module 3. Since the air box 4 adopts an open design, the driving module 3 is placed on the body 1 and fixed, and then the air box 4 is put on the chain 5;

[0085] S2, when the window opener is opened, the sensor will not respond, and the cleaning part remains stationary. Once the chain 5 on the window opener is retracted, the sensor will sense the chain 5 being retracted, and will send a signal to the driving module 3, and the driving module 3 will operate;

[0086] S3, the operation of the driving module 3 will drive the gas injection component 8 to operate, and the gas is injected into the gas box 4 through the gas injection component 8, and then the gas is injected into the purge component 7 through the gas box 4, and the dust on the chain 5 is blown away by the purge component 7. At the same time, the driving module 3 will also drive the purge component 7 to reciprocate around the gas box 4 within a certain angle, and the chain 5 is blown away in multiple directions;

[0087] S4. As the chain 5 is recovered, after being blown by the blower assembly 7, the chain 5 is cleaned by the cleaning assembly 6 to clean the dust adhering to the chain 5 again.

[0088] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
