Technical Field
[0001] This application relates to the field of windshield wiper technology, and in particular to a windshield wiper for removing oil film. Background Technology
[0002] Windshield wipers, also known as wipers, wipers, or windshield wipers, are devices used to wipe away raindrops and dust adhering to the windshield of a vehicle in order to improve the driver's visibility and increase driving safety.
[0003] When it rains, the windshield wipers play a crucial role, swishing rainwater from the center of the windshield to the sides or bottom by reciprocating motion, ensuring the driver's visibility is unobstructed. This mechanical device mainly consists of a motor, a linkage mechanism, wiper arms, and wiper blades. The motor, as the power source, drives the linkage mechanism, which in turn drives the wiper arms to swing back and forth. The wiper blades are in close contact with the wiper arms and move along with them, ultimately achieving the function of wiping away rainwater.
[0004] During use, a layer of oily film often forms on car windshields that is difficult to remove. This not only affects the driver's vision but also poses a safety hazard. Currently, windshield wipers on the market are mainly designed to remove rainwater and snow, but they are not very effective at removing oily film.
[0005] In existing technology, before the wipers wipe water, the windshield is manually pretreated with a specialized cleaner or degreaser to remove the oil film. This method is cumbersome and the results are inconsistent.
[0006] Since existing windshield wipers do not have the function of directly removing oil film, they require an additional cleaning step, making them inconvenient to use and with limited cleaning effect, and therefore need to be improved. Utility Model Content
[0007] To facilitate the removal of oil film from windshields, this application provides a windshield wiper for removing oil film.
[0008] The windshield wiper for removing oil film provided in this application adopts the following technical solution:
[0009] A windshield wiper for removing oil film includes a wiper body, a wiper blade, and an oil removal device. The wiper blade is disposed on the wiper body and is used to wipe water off the windshield. The oil removal device is disposed on the wiper body and communicates with the water outlet of the wiper body. An oil-removing substance is placed inside the oil removal device. The wiper body has a plurality of water inlets, each of which communicates with the water outlet of the oil removal device. The water inlets are spaced apart along the length of the wiper blade.
[0010] By adopting the above technical solution, when the wipers are working, the water from the wiper body's outlet flows through the oil removal device, and the cleaning fluid carrying oil-removing substances is sprayed from the water inlet onto the windshield. As the wipers move, the water carrying the oil-removing substances effectively removes the oil film on the windshield. This combination of chemical reaction and mechanical scraping achieves convenient removal of the oil film from the windshield.
[0011] Preferably, the degreasing device includes a box body, a box cover, and a storage net. The box body has a receiving cavity, the box cover is detachably connected to the box body, and the storage net is disposed in the receiving cavity and is used to place the degreasing substance.
[0012] By adopting the above technical solution, oil-removing substances such as effervescent tablets can be placed on the storage net, and water flows from top to bottom into the receiving cavity. After the water comes into contact with the effervescent tablets, it passes through the storage net and is finally sprayed onto the windshield from each water inlet for subsequent cleaning by the wiper blade.
[0013] Preferably, the lid is connected to the box body by screws.
[0014] By adopting the above technical solution, when the effervescent tablets are used up, the user can open the cap and add more effervescent tablets to the storage net to facilitate the subsequent cleaning of the oil film.
[0015] Preferably, the wiper blade is detachably connected to the wiper body.
[0016] By adopting the above technical solution, when the wiper blade is damaged, it can be removed from the wiper body for replacement, reducing the maintenance cost of the wiper.
[0017] Preferably, the wiper body is connected to a plurality of locking posts, each of the locking posts being spaced apart along the length of the wiper body, and the wiper blade having a corresponding locking groove, the wiper blade being inserted into the locking posts.
[0018] By adopting the above technical solution, the slots on the wiper blade can be inserted into each pin, and the wiper blade and the wiper body can be detachably connected by static friction and pressure.
[0019] Preferably, a limiting protrusion is connected to the locking post, and the inner diameter of the locking groove is smaller than the outer diameter of the limiting protrusion.
[0020] By adopting the above technical solution, after the locking pin is fully inserted into the slot, the limiting protrusion ring will exert a squeezing force on the wiper blade due to its large diameter, thereby further improving the stability of the connection between the wiper blade and the wiper body.
[0021] Preferably, the cross-sectional diameter of the limiting protrusion ring first increases and then decreases along the direction away from the wiper body.
[0022] By adopting the above technical solution, the cross-sectional diameter of the limiting protrusion ring first increases and then decreases along the direction away from the wiper body, which makes it convenient to lock the wiper blade onto the retaining post or to release it from the retaining post.
[0023] Preferably, a rubber layer is provided on the inner wall of the card slot.
[0024] By adopting the above technical solution, the rubber layer has elastic deformation capability. When the clip is engaged in the slot, the rubber layer will deform and generate elastic force. The elastic force reacts on the clip, improving the stability of the scraper after installation.
[0025] Preferably, the outer surface of the wiper body is provided with a paint layer.
[0026] By adopting the above technical solution, the paint layer can not only improve the appearance of the wiper body, but also increase its corrosion resistance and extend its service life.
[0027] Preferably, the wiper body is made of steel or alloy material.
[0028] By adopting the above technical solutions, steel or alloy materials have good strength and are suitable as the frame of the windshield wiper, thereby reducing the possibility of damage to the wiper body.
[0029] In summary, this application includes at least one of the following beneficial technical effects:
[0030] (1) By integrating the oil removal device into the wiper body, the function of removing oil film at the same time during the wiping process is realized, simplifying the operation steps; by utilizing the chemical action of oil removal substances such as effervescent tablets, the effect of removing oil film is improved, ensuring safety during driving and reducing safety hazards such as poor visibility caused by windshield oil stains.
[0031] (2) By setting up a locking post, the locking post and the locking groove cooperate with each other to achieve a detachable connection between the wiper blade and the wiper body. When the wiper blade is damaged, it can be removed from the wiper body to replace it, thus reducing the maintenance cost of the wiper.
[0032] (3) By setting a paint layer, the paint layer can improve the appearance of the outer surface of the wiper body. Attached Figure Description

[0041] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.
[0042] This application discloses a windshield wiper for removing oil film. (Refer to...) Figure 1The windshield wiper includes a wiper body 1, a wiper blade 2, and an oil removal device 3. The wiper body 1 is made of steel or alloy material, which has good strength and is suitable as the wiper frame, thus reducing the possibility of damage and extending its service life. The outer surface of the wiper body 1 is also coated with a paint layer. This paint layer not only improves the appearance of the wiper body 1 but also increases its corrosion resistance and extends its service life. The wiper blade 2 is mounted on the wiper body 1 and is made of a flexible material (such as rubber) to remove water from the windshield. The oil removal device 3 is mounted on the wiper body 1 and communicates with the water outlet of the wiper body 1. The oil removal device 3 contains an oil-removing substance. Several water inlets 4 are provided on the wiper body 1, spaced apart along the length of the wiper blade 2, and each water inlet 4 communicates with the water outlet of the oil removal device 3.
[0043] When the wipers are working, water from the wiper body 1 flows through the oil removal device 3, and cleaning fluid carrying oil-removing substances is sprayed onto the windshield from the water inlet 4. As the wipers move, the water carrying the oil-removing substances effectively removes the oil film on the windshield. By combining chemical reaction and mechanical scraping, the oil film on the windshield can be easily removed.
[0044] Combination Figure 2 Specifically, the degreasing device 3 includes a housing 31, a cover 32, and a storage net 33. The housing 31 has a receiving cavity 7, and the cover 32 is detachably connected to the housing 31 by screws. The storage net 33 is installed in the receiving cavity 7 and is used to hold degreasing substances (such as effervescent tablets). The water outlet of the wiper body 1 is connected to the housing 31 and is located above the storage net 33.
[0045] Effervescent tablets and other oil-removing substances can be placed on the mesh 33. Water flows from top to bottom into the receiving cavity 7, contacts the effervescent tablets, passes through the mesh 33, and is finally sprayed onto the windshield from the water inlets 4, facilitating subsequent cleaning of the oil film by the wiper blade 2. After the effervescent tablets are used up, the user can open the cap and add more effervescent tablets to the mesh 33 for further oil film cleaning, improving usability.
[0046] Combination Figure 3Furthermore, in some embodiments, the wiper blade 2 is detachably connected to the wiper body 1. When the wiper blade 2 is damaged, it can be removed from the wiper body 1 for replacement, reducing the maintenance cost of the wiper. The wiper body 1 is connected to several locking posts 5, which are spaced apart along the length of the wiper body 1. The wiper blade 2 has several corresponding slots, with each locking post 5 corresponding to a specific slot. The wiper blade 2 is inserted into the locking post 5, and the detachable connection between the wiper blade 2 and the wiper body 1 is achieved through static friction and pressure. A limiting protrusion 6 is also integrally connected to each locking post 5, and the inner diameter of the slot is smaller than the outer diameter of the limiting protrusion 6. When the locking post 5 is fully engaged in the slot, due to the larger diameter of the limiting protrusion 6, it exerts a squeezing force on the wiper blade 2, reducing the possibility of the locking post 5 disengaging from the slot and further improving the stability of the connection between the wiper blade 2 and the wiper body 1.
[0047] The diameter of the limiting protrusion 6 first increases and then decreases along the direction away from the wiper body 1, which facilitates the wiper blade 2 to be engaged with or disengaged from the retaining post 5. A rubber layer is also provided on the inner wall of the retaining groove. This rubber layer has elastic deformation capability; when the retaining post 5 is engaged in the groove, the rubber layer deforms and generates elastic force. This elastic force reacts on the retaining post 5, improving the stability of the wiper blade 2 after installation.
[0048] The implementation principle of a windshield wiper for removing oil film according to an embodiment of this application is as follows: When the wiper is working, water from the outlet of the wiper body 1 flows through the oil removal device 3, and cleaning fluid carrying oil-removing substances is sprayed from the water inlet 4 onto the windshield. As the wiper moves, the water carrying oil-removing substances can effectively remove the oil film on the windshield. By combining chemical reaction and mechanical scraping, the oil film on the windshield can be easily removed, ensuring driving safety and reducing safety hazards such as poor visibility caused by oily windshields.
[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
