Of course, other embodiments may employ other shapes of the card slot 132, such as cross-shaped, I-shaped, X-shaped, etc. When the driver needs to replace the wiper rubber strip 110, the driver only needs to take out the chuck 112 of the wiper rubber strip 110 from the clamping groove 132 and then place the new wiper rubber strip 110 in the clamping groove. The arrangement of the clamping manner of the clamping head 112 and the clamping groove 132 facilitates the user to replace the wiper rubber strip 110 with a new one in time, thereby prolonging the service life of the wiper 100. Of course, in other embodiments, the wiper blade 110 and the brush body 130 may be connected in other manners, such as fixed connection.

Further, in order to make the connection between the wiper blade 110 and the brush body 130 more tight, a fastener (not shown) is disposed on an inner wall of the clamping groove 132, and the fastener may be adhered to the inner wall of the clamping groove 132 by an adhesive. The fastener may fill the gap between the slot 132 and the chuck 112 when the two are mated, making the mating of the two more tight and stable. While the user inserts the cartridge 112 into the slot 132, other embodiments may also be used to secure the cartridge 112, such as by adhering a fastener to the outer surface of the cartridge 112. The fastener may be a sponge, although other materials, such as rubber, foam, cotton, etc., having elasticity may be used in other embodiments.

As shown in fig. 1 and 3, a plurality of nozzles 134 are disposed at intervals along a length direction at one end of the brush body 130 away from the wiper rubber strip 110, and the nozzles 134 are used for spraying water to the windshield and then cooperate with the wiper rubber strip 110 to achieve the purpose of cleaning the windshield. Spray head 134 includes a draft tube 135 and a plurality of branch tubes 136. The draft tube 135 is used to connect a plurality of branch tubes 136, and the branch tubes 136 are used to provide a spray passage for water or detergent.

In other embodiments, the branch 136 may take other forms of design. For example, referring to FIG. 4, FIG. 4 shows an alternative arrangement of the branch pipes 136. The draft tube 135 is connected with 3 branch tubes 136, and each branch tube 136 is communicated with the draft tube 135.

One end of the draft tube 135 is rotatably connected to the brush body 130, and the other end is connected to a plurality of branch tubes 136. In this embodiment, the draft tube 135 is cylindrical, however, other embodiments may also use other methods as long as the draft tube 135 is ensured to be communicated with the branch tubes 136, for example, the draft tube 135 is communicated with the branch tubes 136 in the form of square openings.

In this embodiment, the rotational connection of the drain tube 135 and the brush body 130 is achieved by motor drive. Referring to fig. 5, fig. 5 is a schematic view illustrating the connection between the drainage tube 135 and the brush body 130. The brush body 130 is provided with a micro motor 140, and the drainage tube 135 is in transmission connection with the micro motor 140 through a coupling 142. The brush body 130 is rotatably connected with the drainage tube 135 through a rotary sealing member 131, the drainage tube 135 is provided with a protective cover 133, the protective cover 133 is connected with a rotating shaft 144, and the rotating shaft 144 is in transmission connection with the micro motor 140 through a coupling 142. When the micro motor 140 rotates, the shaft coupling 142 drives the rotating shaft 144 to rotate, so as to drive the drainage tube 135 and the branch tubes 136 to rotate synchronously. The rotary sealing member 131 is a rotary sealing ring, but in other embodiments, the rotary sealing member 131 may be a rotary sealing joint. The arrangement of the rotary sealing member 131 ensures that the drainage tube 135 is rotatably connected with the brush body 130, and avoids the situation that water is sprayed out from the joint when the drainage tube rotates.

When a driver needs to use the spray head 134, the system for controlling the wiper 100 is started, and at the moment, the drainage tube 135 and the branch tubes 136 are driven to synchronously rotate with the micro motor 140 under the action of the coupler 142, so that the sprayed water is ensured to fall on the windshield, the water spraying range is expanded, and the sprayed water is more uniform. Of course, in other embodiments, the spray head 134 may rotate while spraying water by using the centrifugal action of the water flow and the pushing action of the reaction force without using a micro motor, and the structure of the existing garden gardening automatic rotation spray head may be specifically referred to. The arrangement of the drainage tube 135 rotatably connected with the brush body 130 enables the nozzle 134 to rotate 360 degrees, and enlarges the water spraying range and the cleaning area. Be different from traditional water jet, the water jet of the shower nozzle 134 that this embodiment provided has fused to wiper 100 for the water jet is more hidden, receives the air current to influence for a short time, sprays water when wiper 100 swings, and the cleaning performance is better. The drainage tube 135 may be made of plastic, but in other embodiments, other materials may be used, such as rubber, metal, wood, etc.

Further, in order to make the spraying area of the branch pipes 136 larger, the free ends of at least two branch pipes 136 have different inclination angles. For example, the free end of one of the branch pipes 136 is at 90 ° to the draft tube 135, and the free end of the other branch pipe 136 is at 45 ° to the draft tube 135. Due to the different inclination angles of the free ends of the two branch pipes 136, the spraying range of the two branch pipes 136 is larger when water is sprayed.

Referring to fig. 6, fig. 6 is a schematic structural diagram of the branch pipe 136. One end of each branch pipe 136 far away from the drainage pipe 135 is circumferentially provided with a plurality of water outlet holes 137. Apopore 137's setting for branch pipe 136 is more even when the water spray, and the water spray effect is better, prevents that rivers from splashing the waste that leads to the water yield outside windshield too greatly, reduces user's experience degree. The water outlet 137 can be perforated by laser, and the spray head 134 with dense needle holes enables the water to be finer and finer, so that the impact on the windshield is reduced while splashing is prevented.

To facilitate the user to use the wiper 100 in winter, the draft tube 135 and the branch tube 136 are each provided with a second heating assembly. The second heating component adopts a second electric heating belt, and the installation mode of the second electric heating belt is the same as that of the first electric heating belt. The second electric heating belt is mainly used for heating water in the drainage tube 135 and the branch tube 136, and the hot water can be used for better removing mosquito and dead bodies on the windshield and can also be used for rapidly removing substances such as frost, snow and the like on the surface of the windshield.

Further, in the present embodiment, the cross-sectional shape of each branch pipe 136 is a pentagram (not shown), but in other embodiments, the cross-sectional shape of each branch pipe 136 may be other shapes, such as a diamond shape, a rectangle shape, or other irregular raised shapes. Through the irregular arrangement of branch pipe 136 water jet, increased the area of contact of second electric heat tape with branch pipe 136 for the heating effect is better.

In this embodiment, there are 4 nozzles 134 at intervals, each nozzle 134 has 9 branch pipes 136, and each branch pipe 1363 can spray water, but in other embodiments, there may be other numbers of nozzles 134 and branch pipes 136, such as 2, 5, 6, etc. The arrangement of the spray head 134 and the branch pipe 136 avoids the situation that the water sprayed out can not be sprayed at the required position due to the displacement of the water spray nozzle because of long service time, so that the water spraying effect is more ideal, and the dirt on the surface of the windshield can be cleaned more easily.

As shown in fig. 3, the connection member 150 is provided with a first flow guide passage (not shown), the brush body 130 is provided with a second flow guide passage 138, the second flow guide passage 138 is communicated with the first flow guide passage, and the second flow guide passage 138 is communicated with the nozzle 134 through the draft tube 135. When the user uses the windshield wiper, water flows from the first guide passage on the connecting member 150 to the second guide passage 138, then passes through the drainage tube 135 and finally reaches the branch tube 136, and is sprayed on the surface of the windshield under the action of pressure. Further, in order to accelerate the heating speed of the water in the first diversion channel and the second diversion channel 138, the first diversion channel and the second diversion channel 138 are both provided with heating components, and the heating components may be electric heating tapes or electric heating wires.
