Because vehicle-mounted camera installs outside the automobile body more, can receive the influence of weather, road conditions, make the camera lens be infected with the prevention of dirt such as dust, silt and ice and snow to influence the normal shooting of camera. Therefore, the camera needs to be cleaned in time to ensure the normal work of the camera.
The existing camera nozzle adopts an integrated design, fluid flows in a flow channel of the camera nozzle, and is sprayed out particularly after passing through a flow channel with a large corner, so that splashing and liquid dropping are easy to occur, the cleaning performance of the nozzle is seriously affected, and cleaning liquid is wasted.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems that fluid flows in a flow channel of the existing camera nozzle, particularly is sprayed out after passing through a flow channel with a large corner, so that splashing and liquid dropping are easy to occur, the cleaning performance of the nozzle is seriously influenced, and meanwhile, cleaning solution is wasted.
The purpose of the utility model can be achieved by adopting the following technical scheme:
an insert type fan-shaped camera cleaning nozzle comprises a joint with the tail end hermetically connected with a water supply pipe, and a nozzle body fixedly sleeved at the front end of the joint; liquid flow channels are arranged in the joint and the nozzle body, and one-way valves are connected in series in the liquid flow channels of the joint and the nozzle body; an insert is arranged in an outlet of the flow channel of the nozzle body, and an L-shaped channel communicated with the flow channel of the nozzle body is arranged in the insert; the diameter of the L-shaped channel is smaller than that of the flow channel of the nozzle body, and the outlet of the L-shaped channel is provided with a V-shaped shape.
Preferably, the check valve includes a valve body for opening or closing the fluid passage of the connector, and an elastic member for pushing the valve body to open or close the fluid passage of the connector, and both ends of the elastic member respectively press the nozzle body and the valve body.
Preferably, an annular retainer ring is arranged on the outer circumference of the nozzle body, and a seal ring is arranged on the annular retainer ring.

The implementation of the utility model has the following beneficial effects:
the cleaning solution is delivered by the vehicle pump system to a fluid flow channel in the fitting. When the pressure in the liquid flow channel is larger than the opening pressure of the one-way valve, the one-way valve is opened to enable the washing liquid to flow into the liquid flow channel of the nozzle body from the liquid flow channel of the joint; and then into the "L" shaped channel of the insert. The "L" shaped channels include axial channels and radial channels. The polyester washing liquid firstly enters the axial channel and then enters the radial channel, and then deflects by 90 degrees and enters the radial channel of the insert; because the diameter of the axial channel and the radial channel of the insert is smaller than that of the flow channel of the nozzle body, the washing liquid passing through the axial channel and the radial channel of the insert can be sprayed out of the radial channel more stably and uniformly. And a V-shaped groove is arranged at the outlet of the L-shaped channel. After the washing liquid is sprayed from the outlet of the L-shaped channel, the uniform and symmetrical fan-shaped spraying liquid flow is formed under the guiding action of the V-shaped groove, and the washing liquid spraying device has the advantages of simple structure, uniform spraying, stability and reliability

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Examples
Referring to fig. 1 to 3, the present embodiment relates to a nozzle, which includes a connector 1 having a rear end hermetically connected to a water supply pipe, and a nozzle body 2 fixedly fitted to a front end of the connector 1; liquid flow channels are arranged in the joint 1 and the nozzle body 2, and the check valve 3 is connected in series in the liquid flow channels of the joint 1 and the nozzle body 2; an insert 4 is arranged in an outlet of the liquid flow channel of the nozzle body 2, and an L-shaped channel 41 communicated with the liquid flow channel of the nozzle body 2 is arranged in the insert 4; the diameter of the "L" -shaped passage 41 is smaller than that of the flow passage of the nozzle body 2, and the outlet of the "L" -shaped passage 41 is provided in a "V" -shaped form.
In operation, washing liquid is delivered by the vehicle pump system to the liquid flow channel in the fitting 1. When the pressure in the liquid flow channel is greater than the opening pressure of the check valve 3, the check valve 3 is opened to allow the washing liquid to flow from the liquid flow channel of the joint 1 into the liquid flow channel of the nozzle body 2; and then into the "L" shaped passage 41 of the insert 4. The "L" shaped passage 41 includes an axial passage 42 and a radial passage 43. The polyester washing liquid firstly enters the axial passage 42 and then enters the radial passage 43, and then deflects by 90 degrees to enter the radial passage 43 of the insert 4; since the axial passage 42 and the radial passage 43 of the insert 4 have a smaller diameter than the flow passage of the nozzle body 2, the washing liquid passing through the axial passage 42 and the radial passage 43 of the insert 4 can be more stably and uniformly sprayed from the radial passage 43. The outlet of the L-shaped channel 41 is provided with a V-shaped groove 44. After the cleaning liquid is sprayed from the outlet of the L-shaped channel 41, uniform and symmetrical fan-shaped spraying liquid flow is formed under the guiding action of the V-shaped groove 44, the fan-shaped spraying liquid flow has the advantages of simple structure, uniform spraying, stability and reliability, and the problems that the cleaning liquid flows in the flow channel of the existing camera nozzle, particularly the cleaning liquid flows through the flow channel with a large rotation angle, splashing and liquid dropping are easy to occur, the cleaning performance of the nozzle is seriously influenced, and meanwhile, the cleaning liquid is wasted are solved.
The check valve 3 comprises a valve body 31 for opening or closing the liquid flow passage of the joint 1, and an elastic member 32 for pushing the valve body 31 to open or close the liquid flow passage of the joint 1, wherein two ends of the elastic member 32 respectively press the nozzle body 2 and the valve body 31. When the pressure in the flow passage of the adapter 1 is higher than the elastic force of the elastic member 32, the liquid pushes the valve body 31 to open the outlet of the flow passage of the adapter 1, so that the liquid flows from the flow passage of the adapter 1 into the flow passage of the nozzle body 2. When the pressure in the liquid flow channel of the joint 1 is smaller than the elastic force of the elastic member 32, the elastic force of the elastic member 32 pushes the valve body 31 to slide in the direction of the joint 1 to close the liquid flow channel of the joint 1.
An annular retainer ring 21 is arranged on the outer circumference of the nozzle body 2, and a sealing ring 22 is arranged on the annular retainer ring 21.
The sealing ring 22 is a gasket or an O-ring. Of course, other sealing members, such as V-rings, may be used according to different requirements.
The elastic member 32 is a spring. Of course, other materials with better elasticity can also be used as the elastic member 32.
The tail end of the joint 1 is hermetically connected with a water supply pipe through a second sealing ring. Under the sealing of the second sealing ring, liquid flowing from the water supply pipe to the tail end of the joint 1 cannot leak from the gap between the water supply pipe and the tail end of the joint 1.
While the utility model has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the utility model is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
