Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention. The following embodiments and features of the embodiments may be combined with each other without conflict.

In the prior art, when bad driving weather conditions, such as rain and snow weather or sand weather, the windscreen wiper can effectively scrape rain and snow water or sand dust accumulated on the windscreen, thereby avoiding shielding of sight and ensuring driving safety of a driver. Therefore, the wiper blade has become one of the devices required for improving the running safety of the vehicle at present.

In the actual wiping process of the windscreen wiper, the A columns are arranged at two ends of a wiping path of the windscreen wiper, and are stand columns positioned at two sides of the windscreen on the frame and used for fixing the windscreen. In order to avoid interference between the windscreen wiper and the A-pillars at two sides of the windscreen of the frame due to overlarge swinging amplitude of the windscreen wiper, a spacing of about 60mm is usually arranged between the limiting angle position of swinging of the windscreen wiper and the A-pillars. However, the distance is outside the wiping range of the windscreen wiper, and the dirt is accumulated for a long time and is not cleaned in place, so that the dirt is difficult to effectively wipe off, and the visual field of a driver is influenced. And in driving in rainy days, raindrops falling at the distance between windshields, and rainwater scraped to the distance by the wiper may also interfere with the driver's view.

Therefore, the range of the wiper in the driving process in the rainy day is limited, the wiper is not thorough, the driving visual field is further poor, and the driving safety is affected.

In order to overcome the defect in the prior art, the application provides a wiper structure of a vehicle and the vehicle, so as to solve the problems that the conventional wiper is limited in wiping range and incomplete in wiping, so that driving vision is poor and driving safety is low.

The present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can more clearly understand the present invention.

The wiper structure of the vehicle and the vehicle provided by the present application are described in detail below with reference to fig. 1 to 6.

As shown in fig. 1, the wiper structure of the vehicle provided by the present application includes a wiper body 100, an air injection mechanism 200, a rotation angle sensor 300, and an air compressor 400, and the air injection mechanism 200 and the rotation angle sensor 300 are disposed on the wiper body 100.

As shown in fig. 1 and 5, the air injection mechanism 200 includes a main air passage 210 and a plurality of air injection passages 211, the main air passage 210 communicates with the plurality of air injection passages 211, and the main air passage 210 communicates with the air compressor 400. The rotation angle sensor 300 is used for detecting a rotation angle of the wiper body 100, when the rotation angle of the wiper body 100 is greater than or equal to a preset rotation angle, the air injection air passages 211 are opened, the air compressor 400 supplies compressed air for cleaning a first preset area 620 to each air injection air passage 211 through the main air passage 210, the first preset area 620 is located outside the swinging range of the wiper body 100, and when the rotation angle of the wiper body 100 is less than the preset rotation angle, the air injection air passages 211 are closed.

It will be appreciated that the wiper body 100 includes a wiper assembly 110, a wiper swing arm 120, and a drive train. The windshield wiper assembly 110 is used for directly contacting with the windshield 600 to realize a wiping action; the wiper swing arm 120 is hinged with the wiper assembly 110, and is used for driving the wiper assembly 110 to swing synchronously through the swing of the wiper swing arm; the driving rod is in transmission connection with the wiper swing arm 120, and the driving rod can do reciprocating motion through the rotation of the motor, so as to drive the wiper swing arm 120 to swing.

The air injection mechanism 200 is disposed on the wiper assembly 110 of the wiper body 100, so as to maintain the synchronous motion of the air injection mechanism 200 and the wiper assembly 110, and improve the air injection efficiency of the air injection mechanism 200. The rotation angle sensor 300 is disposed on the wiper swing arm 120, and the air injection mechanism 200 is controlled by using the rotation angle sensor 300, so that the rotation angle of the wiper body 100 is sensed by the rotation angle sensor 300 more sensitively, and the injection accuracy of the compressed air can be higher, and the injection efficiency is higher.

Wherein the main air duct 210 of the air injection mechanism 200 communicates directly or indirectly with the air compressor 400. The air injection air passage 211 is communicated with the main air passage 210, so that the air compressor 400 can be utilized to provide compressed air for the air injection air passage 211, so that the wiper body 100 ejects the compressed air while wiping, and the area which cannot be directly wiped by the wiper assembly 110 is cleaned, so that the wiping range of the wiper is widened, and the wiping efficiency is improved.

It should be noted that, the preset rotation angle is not unique, but is not greater than the maximum rotation angle of the wiper swing arm 120. Assuming that the maximum rotation angle of the wiper swing arm 120 is 45 °, 43 ° may be set as the preset rotation angle, so when the wiper swing arm 120 of the wiper body 100 rotates 43 ° from the initial position, the air injection passage 211 will inject compressed air to clean the first preset area 620 located between the wiper assembly 110 and the a-pillar 610. In this process, the air jet air passage 211 may continuously jet compressed air until the wiper swing arm 120 rotates to 45 ° and returns to 43 ° again, and the compressed air jet is stopped; alternatively, the air-jet air passage 211 may jet a set amount of compressed air at a time when the wiper arm 120 rotates to 43 °, and close the air-jet air passage 211 when the wiper arm 120 returns to 43 °, which is not particularly limited herein.

In addition, it should be noted that, in the present embodiment, the preset area on the windshield 600 mainly includes the first preset area 620 located between the maximum rotation angle position of the wiper body 100 and the a-pillar 610, and may also include the second preset area 630 located outside the arc of the actual wiping range of the wiper body 100, where the setting position of the air injection air passage 211 on the wiper body may be adjusted to achieve the cleaning requirements of different preset areas, which is not limited herein.

It can be appreciated that the wiper structure of the vehicle of the present embodiment is configured such that the air injection mechanism 200 and the rotation angle sensor 300 are disposed on the wiper body 100, so that the compressed air provided by the air compressor 400 is utilized to clean the first preset area 620 when the rotation angle of the wiper body 100 is greater than or equal to the preset rotation angle. This can expand the actual wiping range of the wiper body 100 and can also improve the wiper wiping efficiency.

Optionally, as shown in fig. 1, 2 and 5, the wiper body 100 further includes a wiper housing 111, and the wiper housing 111 has a cavity therein, an extending direction of the cavity is consistent with an extending direction of the wiper housing 111, and the cavity forms the main air passage 210. One side of the wiper housing 111 is provided with a plurality of through holes communicating with the cavity, and the through holes constitute an air injection passage 211.

It should be noted that, the wiper housing 111 is a housing of the wiper assembly 110, so that a cavity is provided in the wiper housing 111 as the main air channel 210, and a plurality of through holes communicated with the cavity are provided on one side of the wiper housing 111 as the air injection air channels 211, that is, the air injection mechanism 200 is directly processed on the housing of the wiper assembly 110, so that the housing of the air injection mechanism 200 is prevented from being connected with the housing of the wiper assembly 110, and the wiper structure of the vehicle is more compact and portable.

And because the air-jet air passage 211 is formed by the through hole communicated with the cavity, the air-jet angle and the air-jet direction of the air-jet air passage 211 can be adjusted by changing the specific processing angle and the processing position of the through hole. For example, as shown in fig. 6, by processing a through hole with an included angle of 45 ° with the windshield 600, the air jet air passage 211 can jet compressed air to the first preset area 620 with an included angle of 45 °, and the through hole can be further opened at one end of the wiper housing 111 far away from the wiper swing arm 120 to form the air jet air passage 211 with the extending direction of the main air passage 210, and the air jet air passage 211 can jet air to the second preset area 630 outside the arc of the actual wiping range of the windshield wiper body 100, so that the utilization rate of the air jet air passage 211 is further improved, the air jet range of the air jet mechanism 200 is enlarged, and the air jet mechanism can be adjusted according to the specific use requirement of the air jet mechanism 200.

Alternatively, as shown in fig. 2 and 5, a plurality of air injection passages 211 are provided at intervals along the extending direction of the wiper housing 111.

Therefore, it can be considered that the through holes for forming the air injecting passages 211 are mainly located at one side of the wiper housing 111 close to the a-pillar 610, and the air injecting passages 211 are parallel and have consistent intervals therebetween, so that the air injecting density of the air injecting mechanism 200 is more uniform, the overall effect of air injecting cleaning is improved, and the cleaning of the first preset area 620 by the air injecting mechanism 200 is more facilitated.

Optionally, as shown in fig. 3, the air injection mechanism 200 further includes a piston switch 220, the piston switch 220 including a piston 221, an air passage barrier 223, and an electromagnetic control assembly 224. The piston 221 is disposed on the wiper housing 111, the air passage blocking piece 223 is fixedly connected with the piston 221, and the area of the air passage blocking piece 223 is not smaller than the area of the air injection air passage 211, and the air passage blocking piece 223 is used for opening or closing the air injection air passage 211 under the driving of the piston 221. The electromagnetic control component 224 is electrically connected to the rotation angle controller, and the electromagnetic control component 224 is used for controlling the piston 221 to act so as to drive the air passage baffle 223 to open or close the air injection air passage 211.

It can be appreciated that by providing the piston switch 220 on the air injection mechanism 200, the opening and closing of the air injection air passage 211 can be controlled, so that the wiper structure of the vehicle is more refined, and the air injection mechanism 200 can be controlled flexibly and safely.

It should be noted that, to facilitate the installation and control of the piston switch 220, a plurality of pistons 221 may be provided along the extending direction of the wiper housing 111, and the pistons 221 may be provided outside the wiper housing 111. The number of the air passage baffles 223 should be consistent with the number of the air injection air passages 211, and the air passage baffles 223 located within the same length range of the piston 221 are fixedly connected with the piston 221 through the same connecting part 2231, and the connecting part 2231 enables the air passage baffles 223 to be perpendicular to the piston 221, so that the piston 221 and the air passage baffles 223 are convenient to install, and meanwhile the piston 221 can conveniently drive the air passage baffles 223 to move at one time, so that the opening or closing of the air injection air passages 211 is controlled, and the control efficiency of the piston 221 is improved. By making the area of the air passage barrier 223 not smaller than the area of the air injection air passage 211, it is also convenient to ensure that the air passage barrier 223 can effectively close the air injection air passage 211.

In some embodiments, the piston 221 may also be disposed inside the wiper housing 111, so that the wiper structure of the vehicle is more compact, which is not limited herein.

The electromagnetic control component 224 is used for controlling the action of the piston 221, and the electromagnetic control component 224 is electrically connected with the rotation angle sensor 300, so that the consistency and reliability of the wiper structure of the vehicle are enhanced, and the control process is simplified. Therefore, the controller inherent to the wiper structure of the vehicle can be utilized to realize the on-off control of the air injection air passage 211 without connecting the rotation angle sensor 300 with the controller of the vehicle, so that the wiper structure of the vehicle is more independent, and the wiper structure of the vehicle is convenient to independently control and overhaul. Or the rotation angle sensor 300 may be directly electrically connected to the controller of the vehicle itself, so that the cost of the wiper structure of the vehicle is saved, which is not particularly limited in this embodiment.

Optionally, an airway baffle 223 is inserted into the cavity.

It should be noted that, no matter the piston 221 is disposed inside or outside the wiper housing 111, the air passage blocking piece 223 may be inserted into the cavity of the wiper housing 111, so that on one hand, the wiper structure of the vehicle is more compact, on the other hand, the movement effect of the air passage blocking piece 223 caused by external impurities can be avoided, and the air passage blocking piece 223 is convenient to abut against the wiper housing 111 from the inside, so that the closing effect of the air passage blocking piece 223 on the air injection air passage 211 is improved. When the piston 221 is disposed outside the wiper housing 111, a strip-shaped through hole corresponding to the moving path of the air passage blocking piece 223 needs to be formed on the wiper housing 111, so that the air passage blocking piece 223 is inserted into the cavity.

In some examples, the air passage blocking piece 223 may be disposed on the outer side of the wiper housing 111 according to specific situations, so that the air passage blocking piece 223 covers the air injection air passage 211 from the outer side of the wiper housing 111 to realize the on-off control of the air injection air passage 211, and correspondingly, the piston 221 needs to be adaptively adjusted, which is not limited in this embodiment.

Alternatively, as shown in fig. 3 and 4, the piston 221 includes a piston rod 2211 and a piston slide 2212, the piston slide 2212 is disposed on the wiper housing 111, the piston rod 2211 is inserted into the piston slide 2212, and the piston rod 2211 is slidably engaged with the piston slide 2212. The air passage baffle 223 is fixedly connected with the piston 2211. The solenoid control assembly 224 is used to control the movement of the piston slide 2211 relative to the piston slide 2212.

It should be noted that the piston slide 2212 is attached above the wiper housing 111, and the piston slide 2212 has a groove corresponding to the extending direction of the wiper housing 111, the piston 2211 is inserted into the groove, and is also located above the wiper housing 111, and the piston 2211 can slide in the groove parallel to the upper surface of the wiper housing 111, so that the piston 2211 is slidably engaged with the piston slide 2212. The upper end of the air passage barrier 223 within the length range of the piston 2211 is provided with a connecting part 2231, a plurality of air passage barriers 223 are fixedly connected with the connecting part 2231, and the connecting part 2231 is fixedly connected with the air passage barriers 223. The air passage blocking piece 223 may be perpendicular to the piston piece 2211 and parallel to the side of the wiper housing 111 where the air injection passage 211 is located by the connection portion 2231.

Thus, the electromagnetic control component 224 can make the piston 2211 reciprocate in the groove of the piston slide 2212, and make the piston 2212 move synchronously with the piston 2211 and the air passage barrier 223, so as to realize the switch control of the air injection air passage 211.

Optionally, electromagnetic control assembly 224 includes electromagnetic coil 2241, magnet 2242. Solenoid 2241 is provided on wiper housing 111, and solenoid 2241 is electrically connected with rotation angle sensor 300, magnet 2242 is provided on piston piece 2211, and magnet 2242 is located at an end of piston piece 2211 near solenoid 2241. When the rotation angle of the wiper body 100 is greater than or equal to the preset rotation angle, the electromagnetic coil 2241 attracts the magnet 2242, and the piston 2211 drives the air passage blocking piece 223 to move relative to the wiper housing 111, so that the air passage blocking piece 223 is staggered with the air injection air passage 211.

It will be appreciated that electromagnetic control assembly 224 is comprised of solenoid 2241 and magnet 2242, which is relatively simple in construction and easy to install. Since electromagnetic coil 2241 is energized to make it magnetic and thus attract the magnetic paste, electromagnetic coil 2241 may be disposed on a mechanism or component stationary with respect to magnet 2242, such as wiper housing 111 or piston slide 2212, and magnet 2242 may be disposed at an end of piston member 2211 adjacent to electromagnetic coil 2241, thereby attracting piston member 2211 to move toward electromagnetic coil 2241 by energizing electromagnetic coil 2241 to move air passage flap 223 with respect to wiper housing 111.

It should be noted that, the air duct barrier 223 is set to cover the air duct 211 in a normal case, so that the air duct 211 is in a closed state, and when the electromagnetic coil 2241 is energized, the air duct barrier 223 may be moved until it is staggered from the air duct 211, so that the air duct 211 is in an open state. To normally close the jet air passage 211 and open the jet air passage 211 when the solenoid 2241 is energized, it is necessary to keep a space between the solenoid 2241 and the magnet 2242 and a space between the piston piece 2211 and an end of the piston slide 2212 where the solenoid 2241 is provided, when the solenoid 2241 is energized, to attract the magnet 2242 on the piston piece 2211 and to stagger the air passage barrier 223 from the jet air passage 211.

Therefore, when the rotation angle of the wiper body 100 is greater than or equal to the preset rotation angle, the rotation angle sensor 300 sends a signal, and the electromagnetic coil 2241 is energized and attracts the magnet 2242, so that the piston 2211 connected with the magnet 2242 drives the air passage barrier 223 to move relative to the wiper housing 111, so that the air passage barrier 223 is staggered with the air injection air passage 211.

Optionally, the electromagnetic control assembly 224 further includes a return spring 2243, the return spring 2243 being disposed between the piston plate 2211 and the piston slide 2212, and the return spring 2243 being located at an end of the piston plate 2211 remote from the electromagnetic coil 2241. When the rotation angle of the wiper body 100 is smaller than the preset rotation angle, the electromagnetic coil 2241 is separated from the magnet 2242, and the return spring 2243 drives the air passage blocking piece 223 to move reversely relative to the wiper housing 111, so that the air passage blocking piece 223 covers the air injection air passage 211.

It will be appreciated that in order to achieve movement of the piston 2211 in opposite directions within the piston slide 2212, the same solenoid 2241 and magnet 2242 need to be provided without a return member at the other end of the piston 2211 so that the solenoid 2241 may attract the magnet 2242 from the other end to move it in opposite directions. Thus, in some examples, the wiper housing 111 or the piston slide 2212 is provided with electromagnetic coils 2241 at both end positions of the piston 2211, and magnets 2242 are provided at both ends of the piston 2211 to achieve bidirectional movement of the piston 2211, which is not limited in this embodiment.

Therefore, to avoid the electromagnetic control assembly 224 being provided too much, its structure is too complicated and control is inconvenient. A return spring 2243 may be installed at an end of the piston 2211 remote from the solenoid 2241, and one end of the return spring 2243 is connected to the wiper housing 111 or the piston slide 2212, and the other end is connected to the piston 2211. And when the solenoid 2241 attracts the magnet 2242, the return spring 2243 is in an elongated tension state. Thus, when solenoid 2241 is de-energized and disengages from magnet 2242, return spring 2243 automatically retracts and moves piston 2211, causing airway barrier 223 to re-cover jet airway 211.

Therefore, when the rotation angle of the wiper body 100 is smaller than the preset rotation angle, the rotation angle sensor 300 sends a signal to disengage the electromagnetic coil 2241 from the magnet 2242, the return spring 2243 is contracted, and the return spring 2243 drives the air passage barrier 223 to move reversely relative to the wiper housing 111, so that the air passage barrier 223 covers the air injection air passage 211.

Optionally, as shown in fig. 1, the wiper structure of the vehicle further includes an air duct 500, one end of the air duct 500 is connected to the main air duct 210, and the other end is connected to the air compressor 400. The air duct 500 is provided with an air valve 510, and the air valve 510 is electrically connected with the rotation angle sensor 300. The air valve 510 is used for controlling the air duct 500 to be opened when the rotation angle of the wiper body 100 is greater than or equal to a preset rotation angle, and controlling the air duct 500 to be closed when the rotation angle of the wiper body 100 is less than the preset rotation angle.

It can be appreciated that by providing the air duct 500 between the air injecting mechanism 200 and the air compressor 400, the installation position of the air compressor 400 can be more flexible, and the swinging of the wiper body 100 can be prevented from interfering. Connecting the air duct 500 with the middle of the main air duct 210 facilitates uniform dispersion of compressed air into the jet air duct 211 within the main air duct 210. The air duct 500 is also partially inserted into a part of the structure of the wiper body 100, and specifically partially inserted into the wiper swing arm 120, or may be bundled with the wiper swing arm 120, so that the structure thereof is more compact.

It should be noted that, the air duct 500 is provided with the air valve 510, the air valve 510 is electrically connected with the rotation angle sensor 300, the rotation angle sensor 300 can control the opening and closing of the air valve 510, so that the air valve 510 and the piston switch 220 cooperate with each other to control the circulation of the compressed air together, so as to realize the precise control of the wiper structure of the vehicle.

Thus, when the rotation angle of the wiper body 100 is greater than or equal to the preset rotation angle, the rotation angle sensor 300 sends a signal, the air valve 510 is opened to enable the air duct 500 to be unblocked for compressed air circulation, and when the rotation angle of the wiper body 100 is less than the preset rotation angle, the rotation angle sensor 300 sends a signal, the air valve 510 is closed to enable the air duct 500 to be blocked to interrupt compressed air circulation.

The following describes the operation of the wiper structure of the vehicle with reference to fig. 1 and 6:

1. when the vehicle is started, the air compressor 400 is turned on and pressurizes the air to two atmospheres, 2.026 ×10 ⁵ Pa, and waits for the wiper body 100 to start working;

2. when the wiper body 100 starts to work, the rotation angle sensor 300 starts to run, the limit angle position of the wiper body 100 is set to be 45 degrees, when the rotation angle sensor 300 detects that the rotation angle of the wiper body 100 reaches 43 degrees, a signal is sent to the air valve 510, the air valve 510 is opened, the air duct 500 is conducted, and at the moment, compressed air enters the main air duct 210 of the air injection mechanism 200 from the air duct 500 and is dispersed to the air injection air duct 211 to wait for being injected;

3. when the rotation angle sensor 300 detects that the rotation angle of the wiper body 100 reaches 43 degrees, a signal is sent to the air valve 510, and meanwhile, a signal is sent to the piston switch 220, so that the piston switch 220 positioned on the wiper shell 111 starts to act, the electromagnetic coil 2241 is electrified, the electromagnetic coil 2241 drives the adsorption magnet 2242, the magnet 2242 drives the piston piece 2211 to move together with the air passage baffle 223 until the air passage baffle 223 is staggered with the air injection air passage 211, the air injection air passage 211 is opened, compressed air is injected by the air injection air passage 211, and an included angle of about 45 degrees exists between the injected compressed air and the first preset area 620;

based on practical experience and ideal gas state equation pv=nrt (where P is gas pressure, two atmospheres 2.026 ×10 are taken ⁵ Pa and V are gas volumes, N is the amount of a substance according to specific parameters of the cavity of the wiper shell 111, R is a gas constant, T is the temperature and room temperature are taken, and a pressure formula P=F/S (S is taken as the area of a first preset area 620) is combined to calculate to instantaneously generate a blowing force of about 24500N, wherein the blowing force is large enough to purge the first preset area 620 completely, so that the expansion of the wiping range of the wiper is realized, and the wiping efficiency of the wiper is improved;

4. when the angle sensor 300 detects that the wiper body 100 starts to move back, the electromagnetic coil 2241 is powered off, so that the magnet 2242 is separated from the electromagnetic coil 2241, the return spring 2243 retracts, and the piston piece 2211 is pulled to move reversely, so that the air passage blocking piece 223 is driven to cover the air injection air passage 211, and the air injection air passage 211 is closed;

5. when the rotation angle sensor 300 detects that the rotation angle of the wiper body 100 is returned to 43 °, the rotation angle sensor 300 sends a signal to the air valve 510 to close the air valve 510.

6. The above steps 2-5 will be repeated when the wiper body 100 is operated next time.

It should be noted that, when the second preset area 630 outside the arc shape of the actual wiping range of the wiper body 100 needs to be cleaned, a first preset rotation angle and a second preset rotation angle need to be set, where the second preset rotation angle is still 43 °, the first preset rotation angle may be 15 °, or according to specific requirements, and corresponds to the first preset rotation angle, the air-injection air passage 211 consistent with the extending direction of the wiper housing 111 is set at the end of the wiper housing 111, and the rest of the air-injection air passages 211 are set at one side of the wiper housing 111.

Step 2-5 should be:

2. when the rotation angle sensor 300 detects that the rotation angle of the wiper body 100 reaches 15 degrees, a first signal is sent to the air valve 510, the air valve 510 is opened, the air duct 500 is conducted, and at the moment, compressed air enters the main air duct 210 of the air injection mechanism 200 from the air duct 500 and is dispersed to the air injection air duct 211 to wait for being injected;

3. when the rotation angle sensor 300 detects that the rotation angle of the wiper body 100 reaches 15 degrees, a first signal is sent to the air valve 510, and meanwhile, a first signal is sent to the piston switch 220, so that the piston switch 220 positioned at the end part of the wiper shell 111 starts to act, the electromagnetic coil 2241 is electrified, the electromagnetic coil 2241 adsorbs the magnet 2242, the magnet 2242 drives the piston piece 2211 to move together with the air passage baffle 223 until the air passage baffle 223 is staggered with the air injection air passage 211 at the end part of the wiper shell 111, the air injection air passage 211 is opened, and compressed air is continuously sprayed out by the air injection air passage 211; and when the rotation angle sensor 300 detects that the rotation angle of the wiper body 100 reaches 43 deg., it sends a second signal to open the air injection passage 211 at one side of the wiper housing 111 and inject compressed air.

4. When the angle sensor 300 detects that the wiper body 100 starts to move back, the electromagnetic coil 2241 is powered off, so that the magnet 2242 is separated from the electromagnetic coil 2241, the return spring 2243 is retracted, and the piston piece 2211 is pulled to move reversely, so that the air passage blocking piece 223 is driven to cover the air injection air passage 211, and the air injection air passage 211 is closed together;

5. when the rotation angle sensor 300 detects that the rotation angle of the wiper body 100 is returned to 43 °, i.e., the second preset rotation angle, the rotation angle sensor 300 sends a signal to the air valve 510 to close the air valve 510.
