Abstract
The present invention relates to a vehicle headlamp cleaner which is characterized in that the structure of a guide rod is canister-shaped. A spool valve which is matched with the inside wall of the guide rod is arranged in the guide rod. The guide rod is connected with a nozzle. The spool valve is also connected with one end of an extension spring. The other end of the extension spring is connected with a base plate. A cleaning liquid enters a shell from a cleaning liquid inlet which is arranged on the base plate. Pressure of the cleaning liquid promotes the guide rod to move together with the spool valve. After the guide rod moves to an ultimate place, the guide rod stops moving and the spool valve is propped up, which forms a working loop of the cleaner, and the cleaner begins to work. When the cleaner finishes work, because the pressure of the cleaning liquid disappears and under the pull of a spring, the spool valve is closed and the working loop of the cleaner is closed, so the guide rod moves on under the pull of the extension spring until an initial place is resumed, and the whole cleaning process is finished. The present invention has the advantages of small quantity of components and simple and reliable structure.
Description
Technical field:
The present invention relates to automobile manufacturing field, be specifically related to a kind of cleaner of vehicle headlight.
Background technology:
Vehicle if head lamp is contaminated, makes light generation scattering when driving, produce very big dazzling the eyes, particularly vehicle discharge light can for during meeting the other side's vehicle, causes the illumination of one's own side's road to worsen simultaneously.Therefore, head lamp particularly aerial discharge head lamp should be equipped with Headlamp cleaner, to guarantee traffic safety.The big multiple component of the cleaner of vehicle headlight of available technology adopting is more, complex structure, and fault rate is higher.
Summary of the invention:
The object of the present invention is to provide a kind of cleaner of vehicle headlight simple and reliable for structure.
To achieve these goals, technical scheme of the present invention is as follows: a kind of cleaner of vehicle headlight, comprise shell, and the bottom of shell is provided with base, base is provided with the cleaning liquid import, be provided with pilot bar in the shell, the pilot bar front end is provided with nozzle, it is characterized in that pilot bar is a tubular structure, be provided with the spool that matches with the pilot bar inwall in the pilot bar, pilot bar is connected with nozzle, and spool also is connected with an end of extension spring, and the other end of extension spring is connected with base.Pilot bar is provided with guiding rib, and outer casing inner wall is provided with the guide groove that matches with guiding rib, is provided with sealing arrangement between pilot bar and the outer casing inner wall, and the pilot bar inwall is provided with an inner conical surface, the male cone (strobilus masculinus) of spool outer wall for matching with inner conical surface.The spool bottom is provided with hanger, and extension spring is connected with hanger.The outer casing inner wall front end is provided with the pilot bar limiting stopper that matches with pilot bar, and the nozzle outer wall is provided with the nozzle limiting stopper that matches with the pilot bar front inner wall.
Cleaning liquid enters in the shell from the cleaning liquid import on the base, cleaning fluid pressure promotes the pilot bar motion, under the effect of extension spring, spool moves with pilot bar, after pilot bar moves to end position, the pilot bar stop motion, along with the continuation increasing of cleaning fluid pressure, spool is backed down, and forms the space between spool and the pilot bar inwall, constituted the work loop of cleaning device, cleaning device is started working.When cleaning device after hours because cleaning fluid pressure disappears, under the pulling force of spring, spool is closed, the work loop of cleaning device is closed, pilot bar continues to move under the pulling force of extension spring then, up to recovering initial position, whole cleaning process end.The invention has the advantages that amount of parts is few, simple and reliable for structure.
Description of drawings:
Fig. 1 is structural representation of the present invention (initial condition)
Fig. 2 stretches out for pilot bar of the present invention but structural representation when not spraying water
Structural representation when Fig. 3 sprays water for the present invention
The specific embodiment:
Below in conjunction with drawings and Examples the present invention is elaborated.
A kind of cleaner of vehicle headlight comprises shell 5, and the bottom of shell 5 is provided with base 7, base 7 is provided with the cleaning liquid import, be provided with pilot bar 2 in the shell 5, pilot bar 2 front ends are provided with nozzle 1, it is characterized in that pilot bar 2 and shell 5 inwall sliding block joints, pilot bar 2 is a tubular structure, all there is opening front and back, are provided with the spool 3 that matches with pilot bar 2 inwalls in the pilot bar 2, and pilot bar 2 is connected with nozzle 1, spool 3 also is connected with an end of extension spring 4, and the other end of extension spring 4 is connected with base 7.Pilot bar 2 is provided with guiding rib 8, shell 5 inwalls are provided with the guide groove 10 that matches with guiding rib 8, be provided with sealing arrangement 6 between guiding rib 8 and shell 5 inwalls, shell 5 inwall front ends are provided with the pilot bar limiting stopper 9 that matches with pilot bar 2, pilot bar 2 inwalls are provided with an inner conical surface, the male cone (strobilus masculinus) of spool 3 outer walls for matching with inner conical surface, spool 3 bottoms are provided with hanger 12, and extension spring 4 is connected with hanger 12.In the present embodiment, sealing arrangement 6 is the U RunddichtringO.
When the cleaning device initial position, spool 3 is fixed in the inner conical surface of pilot bar 2 under the effect of extension spring 9.When cleaning liquid when the cleaning liquid import of base 7 enters cleaning device, under the effect of cleaning fluid pressure, pilot bar 2 is together with spool 3 motions, at this moment spool 3 is abutting against under the effect of spring force on the inner conical surface of pilot bar 2, pilot bar 2 moves along a straight line under the directional tagging of the guide groove of cleaning device shell 5, after pilot bar 2 moves to Fig. 2 position, the pilot bar limiting stopper 9 of shell 5 inwalls and the position that pilot bar 2 is limited in Fig. 2.Continuation increasing along with cleaning fluid pressure, when cleaning fluid pressure is enough to overcome extension spring 4 pulling force of this moment, spool 3 is backed down, nozzle 1 outer wall is provided with the nozzle limiting stopper 11 that matches with pilot bar 2 front inner wall, under the help of nozzle limiting stopper 11, spool reaches and remains on control position, as shown in Figure 3, the inner chamber of pilot bar 2 has just formed the work loop of cleaning liquid like this, and cleaning device is started working.When washing equipment after hours because cleaning fluid pressure disappears, spool 3 at first is returned to the inner conical surface of pilot bar 2, close the work loop of cleaning liquid, then, pilot bar 2 continues to move under the pulling force of extension spring 4, up to returning to initial position, whole cleaning process finishes.It should be noted that, the conicoid that has radian is adopted on the surface that spool 3 matches with pilot bar 2, under certain pressure effect, material forms bigger seal area by being out of shape, to strengthen sealing effectiveness, simultaneously can overcompensate use the back because wearing and tearing and former thereby the not enough and poorly sealed situation of distortion that produce such as aging.Owing to need sealing before spool 3 is opened, therefore spool 3 bottoms are airtight, and spool 3 male cone (strobilus masculinus)s are provided with cavity, are communicated with cavity in the nozzle 1, guarantee can also provide spool 3 slides into control position in pilot bar 2 after enough spaces to make cleaning liquid to pass through smoothly.
