[0007] Preferably, the width of the inlet is greater than the width of the outlet, and the cross-sectional shape of the outlet is set to a trumpet shape, so that the water flow can fully enter the interior of the insert and the water flow is accelerated through the small-diameter outlet.

[0008] Preferably, the four filter blocks are equidistantly distributed between the inlet and the diverter block, and the diverter block and the insert are integrally formed, which facilitates mass production.

[0009] Preferably, the diversion block is crescent-shaped, and water passage cavities are left between the two ends of the diversion block and the inner wall of the flow channel, which can divert the water flow.

[0010] Preferably, the housing is provided with a compression spring, and the bottom of the compression spring is provided with a piston that can automatically close the water inlet pipe.

[0011] Beneficial effects

[0012] This invention provides a double-layer nozzle for automobiles. Compared with the prior art, it has the following advantages:

[0013] This anti-clogging double-layer nozzle divides the water flow into two streams via an insert, which enter the flow channel through the inlet. Impurities in the glass cleaner are blocked by the filter block, and after being accelerated by the diverter block, they are mixed and then sprayed out through the small-diameter outlet. This effectively filters impurities in the glass cleaner and allows for easy replacement and installation using the fixed protrusion, thus improving ease of use. Attached Figure Description

[0018] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a double-layer nozzle for automobiles, including a housing 1, a water inlet pipe 3 installed at the bottom of the housing 1, an installation slot 4 opened at the top of the housing 1, a double-layer insertion mechanism 2 inside the installation slot 4, a compression spring 5 inside the housing 1, and a piston 6 at the bottom of the compression spring 5, which can automatically close the water inlet pipe 3 and automatically open the water inlet pipe 3 when the water reaches a certain pressure. The double-layer insertion mechanism 2 can form a small-volume insertion structure and can filter impurities in the windshield washer fluid. It is also convenient to replace and install, effectively improving the convenience of use.

[0020] The double-layer insertion mechanism 2 includes an insert 201, with fixed protrusions 202 fixedly connected to both the front and rear sides of the insert 201. A fixed slot is provided on the inner wall of the housing 1, matching the fixed protrusions 202. The insert 201 is detachably connected to the housing 1 via the fixed slots and fixed protrusions 202, allowing for easy replacement and installation of the insert 201. Flow channels are provided on the top and bottom surfaces of the insert 201, forming a double-layer nozzle structure with the housing 1. Inlet and outlet 205 are respectively provided at both ends of the two flow channels. The width of the inlet is greater than the width of the outlet 205, and the cross-sectional shape of the outlet 205 is funnel-shaped, allowing water to fully enter the nozzle. Inside the insert 201, the water flow is accelerated through a small-diameter outlet 205, while a large-diameter inlet ensures sufficient water intake. Four filter blocks 203 are provided between the inlet and outlet 205, and a diverter block 204 is provided on one side of each filter block 203. The four filter blocks 203 are equidistantly distributed between the inlet and the diverter block 204, which allows the four filter blocks 203 to filter impurities in the glass water and prevent clogging. The diverter block 204 is integrally formed with the insert 201, which facilitates mass production. The shape of the diverter block 204 is crescent-shaped, and water passage cavities are left between the two ends of the diverter block 204 and the inner wall of the flow channel to divert the water flow.

[0021] During operation, water flows into the inlet pipe 3, and after reaching a certain pressure, it pushes open the piston 6 and enters the top of the housing 1. Then, the water flow is divided into two streams by the insert 201 and enters the flow channel through the inlet. Impurities in the glass cleaner are blocked by the filter block 203, and after being divided and accelerated by the diverter block 204, they are mixed and then sprayed out from the small-diameter outlet 205. This can filter the impurities in the glass cleaner and also makes it easy to replace and install using the fixing protrusion 202, effectively improving the convenience of use.
