ABSTRACT:
BACKGROUND OF THE INVENTION
1) Field of the Invention
This invention relates to a multifunction car wash gun structure that improves upon the shortcomings of conventional car wash gun guns that are only capable of providing for the discharge of water alone or a combination of water and soap solution. The present invention is also ergonomically designed in that it provides a directly rotatable adjustment mount for the convenient controlling of the water-off, water-only, combination water and soap, and water and liquid wax output modes of the car wash gun structure.
2) Description of the Prior Art
Conventional car wash gun structures, as indicated in
FIG. 1
,
FIG. 1-A
, and
FIG. 1-B
, are comprised of an adjustable spray nozzle A (the prior art structural convent of which is commonplace and, therefore, needs no further elaboration), a water hose S, an attached connector tube circuit B, and a soap solution input hole B
1
in the top surface of the said connector circuit B. A leakproof gasket is installed at the front and rear faces of the connector tube circuit, with a cleaning solution injector hole formed in the periphery of the top end for the slide operation of the cleaning solution chamber unit C by the connector tube circuit B. After the interior section of the cleaning solution chamber unit C is ensleeved over the connector tube circuit B, the interior section forms a soap solution cavity C
2
for the injection of the soap solution. Finally, the leakproof gaskets C
21
are respectively placed at the two sides of the soap solution input hole B
1
between the front end and annular edge of the soap solution cavity C
2
, and the front end and top surface of the connector tube circuit B. The two leakproof gaskets C
21
allow the entire cleaning solution chamber unit C to slide for purposes of control.
Following the assembly of the aforementioned structure, the water hose S supplies a flow of water into the interior section of the connector tube circuit B to thereby provide output from the end of the nozzle A. When a water-only water flow is desired, the entire cleaning solution chamber unit C is directly slid such that the two leakproof gaskets C
21
nearest the front end and annular edge of the soap solution space C
2
block the soap solution input hole B
1
at the front section and top surface of the connector tube circuit B (as shown in FIG.
1
-B). When a soap solution is desired, the two leakproof gaskets
21
nearest the interior section front end and annular edge of the said soap solution chamber unit F are slid to the soap solution input holes B
1
at the front end and top surface of the connector tube circuit B, causing the said soap solution input hole B
1
to be in communication with the soap solution chamber unit C (as shown in FIG.
1
-A), thereby achieving a mixed flow through the interior section of the connector circuit E to provide a usable water and soap solution.
While the conventional structure is only capable of providing a water-only, or a combination water and soap solution, when utilized as a car wash gun to wash cars, in addition to the soap and water mixture, the application of a wax and water mixture may be desired. It is incapable of such a function and the structural design cannot be enhanced to include a wax water output, with the exception of completely emptying out the soap solution contained in the soap solution chamber unit F and, cleaning and drying it, and then filling the unit with liquid wax. Such a task is quite inconvenient. Otherwise, a separate structural entity that can be filled with liquid wax is a necessary improvement.
Referring to
FIG. 2
,
FIG. 2-A
, and
FIG. 2-B
, another car wash gun structure is comprised of a car wash gun body D having a handle D
1
with a water supply connector at the bottom end, a hollow water passage D
2
disposed internally and a top end extending towards the front. A connector E of tubular shape, the end E
1
of which is inserted into the top end and front extent of the car wash gun body D has receptacles E
2
and E
3
perpendicularly formed at the top and bottom, respectively, in the approximate center section, with an annular groove E
21
formed in the top surface of the upper receptacle E
2
and a threaded section E
31
formed along the bottom end of the lower receptacle E
3
. A through-hole E
4
of a relatively small diameter proceeds along the two receptacles E
2
and E
3
, with the through-hole E
4
having passages E
5
and E
6
formed in the center sectional parallel to the two sides which enable communication with the interior section of the connector E, and an output hole E
7
situated in the lower receptacle E
3
.
The assembly also includes an adjustment mount F having a columnar element F
1
at its upper section and a circular piece F
2
at its bottom section. The top of the circular piece F
2
is positioned with the soap solution output hole F
3
aligned with the output hole E
7
and an outer edge of the columnar element F
1
is against the water-tight ring F
4
attached to the bottom section such that when inserted into the bottom end of the lower receptacle E
3
below the connector E, the upper section is inserted into the through-hole E
4
. This enables continuity between the passages E
5
and E
6
in the through-hole E
4
. A level flow passage F
5
is formed with an annular groove F
6
disposed along its top end and center, and an insertion latch rim F
7
with a mounting hole F
8
in the center is formed at the periphery of the annular groove F
5
.
A sleeve G that is filled with a soap or other cleaning solution has a threaded section G
1
along the top exterior end which enables fastening to the threaded section E
31
.
A setting sleeve H has a rotatable knob H
1
at its top section, a circular skirt H
2
situated at its center section, and a catch slot H
3
at its bottom section in the center of the circumferential edge, thereby enabling a fixed insertive positioning into the insertion latch rim F
7
of the annular groove F
6
disposed along its top end and center of the adjustment mount E. A mounting hole H
4
is formed in the center of its top surface, enabling its fastening to the mounting hole F
8
in the center and top surface of the adjustment mount H by means of the screw H
5
such that when the rotatable knob H
1
on the upper section of the setting sleeve H is turned during operation, the adjustment mount F is simultaneously rotated for purposes of control.
A connective tube I that is of hollow construction has an end which is inserted onto the front end of the connector E to form a unitary structural entity.
A nozzle J is inserted into the front end of the connective tube I to form a unitary structural entity and, furthermore, to provide a range of adjustable spraying patterns.
Following the assembly of this structure, as indicated in
FIG. 2
,
FIG. 2-A
, and
FIG. 2-B
, the user manually rotates and thereby adjusts the rotatable knob H
1
of the setting sleeve H, causing the adjustment mount F to rotate such that the passages E
5
and E
6
in the through-hole E
4
of the connector E above the adjustment mount F are not in continuity with the level flow passage F
5
in the interior section of the connector E, blocking the water flow pathway formed from the end and initial portion of the water passage D
2
placing the car wash gun in the water-off mode, wherein water is prevented from flowing to the connective tube I fastened to the front end of the connector E and precluded form discharging through the nozzle J.
Referring to
FIG. 2
,
FIG. 2-C
, and
FIG. 2-D
, when the user rotates and thereby adjusts the rotatable knob H
1
of the setting sleeve H
1
, the adjustment mount F is rotated along such that passages E
5
and E
6
in the through-hole E
4
of the connector E above the adjustment mount F are in continuity with the level flow passage F
5
in the interior section of the connector E, opening the water flow pathway formed from the end and initial portion of the water passage D
2
inside the car wash gun body D and placing the car wash gun in a water-on mode, wherei
