DETAILED DESCRIPTION

(12) With reference to FIGS. 2, 3 and 7, a spray gun for a kitchen according to a preferred embodiment of the present invention comprises: a connector 20, a body 30, a spraying element 40, an adjustor 50, and a casing 60.

(13) Referring to FIGS. 2, 3 and 7, a first end of the connector 20 is connected with a water supply tube (not shown), and the connector 20 includes a conduit 21 formed on a central section thereof, an inlet 211 defined between the first end of the connector 20 and the conduit 21, and an outlet 212 formed on a second end of the connector 20. To enhance cleaning efficiency and extend a cleaning position, the connector 20 is comprised of a holder 22 and an extending rod 23 so that the spray gun is moved above to a desired washing object/place by using a length of the extending rod 23.

(14) Referring to FIGS. 2, 3 and 7, the body 30 is formed in a T shape and is fixed in front of the second end of the connector 20, and the body 30 includes a guiding channel 31 defined thereof and communicating with the outlet 212, such that tap water is guided to flow to the spraying element 40 via the guiding channel 31. The body 30 includes a press bar 33, a control bolt 34, and a spring 35, wherein the press bar 33 is connected on an outer wall of the body 30, the control bolt 34 is received in the body 30 and is configured to control an open or a close of the guiding channel 31, the spring 35 is connected on a lower end of the control bolt 34 so that the control bolt 34 is configured to maintain the close of the guiding channel 31. To clean an interior of the body 30 and avoid an accumulation/block of incrustant, the body 30 includes a cap 36 mounted on a bottom of the body 30 and configured to connect the control bolt 34 and the spring 35 and to clean the interior of the body 30.

(15) As shown in FIGS. 3-5 and 8-10, the spraying element 40 is fitted onto a front end of the body 30, and the spraying element 40 includes a fixer 41, a valve core 42, a fitting ring 43, a first water supply unit 44, and a second water supply unit 45. The fixer 41 is disposed on the front end of the body 30 and has a switch groove 411 formed on an outer wall of the fixer 41, the valve core 42 is fixed in the fitting ring 43 and is connected with the fixer 41 via the casing 60, and the fitting ring 43 has a first watering path 431 and a second watering path 432. The first water supply unit 44 is mounted on a center of a front end of the fitting ring 43 and is configured to supply the tap water by matching with the first watering path 431, and the second water supply unit 45 is disposed on the front end of the fitting ring 43 surrounding the first water supply unit 44 and is configured to supply the tap water by matching with the second watering path 432.

(16) With reference to FIGS. 2-10, the adjustor 50 is disposed between the body 30 and the spraying element 40 and is formed in a ring shape, wherein the adjustor 50 includes an adjusting stem 51, and the switch groove 411 has a first position 4A and a second position 4B. Referring to FIGS. 5 and 9, the adjusting stem 51 is connected with the valve core 42 via the fixer 41 to actuate the valve core 42 to move in the fixer 41.

(17) As shown in FIGS. 2-10, the casing 60 is fitted on an outer wall of the spraying element 40, and a distal end of the casing 60 is connected on the adjustor 50 so as to move the casing 60 forward or backward to switch the adjusting stem 51 of the adjustor 50 on the switch groove 411 and to actuate the valve core 42 to flow the tap water from a water faucet (not shown) via the first water supply unit 44 or the second water supply unit 45.

(18) As illustrated in FIGS. 4-6, in operation, for example, as desiring to clean residue on a tableware or a water sink, the casing 60 is pulled to move toward the body 30 so that the adjusting stem 51 is located at the first position 4A of the switch groove 411, and the spraying element 40 is pushed forward with respect to the casing 60 to adjust the adjustor 50 finely, such that the adjusting stem 51 is located at the first position 4A, and the valve core 42 stops the second watering path 432. Thereafter, the press bar 33 is pressed so that the control bolt 43 descends to open the guiding channel 31 and the tap water flows to the spraying element 40 from the connector 20, then the tap water further flows to the first water supply unit 44 via the first watering path 431 of the fitting ring 43 to supply the tap water in a water jet mode, hence the tap water is collected to produce a strong washing effect, thus cleaning the residue in the water jet mode.

(19) With reference to FIGS. 9-11, when desiring to clean in a large area, the casing 60 is pulled to move away from the body 30 so that the adjusting stem 51 is located at the second position 4B of the switch groove 411, and the spraying element 40 is moved to retract into the casing 60, then the adjustor 50 is adjusted finely so that the adjusting stem 51 is located at the second position 4B, as shown in FIG. 11, wherein the valve core 42 stops the first watering path 431 of the fitting ring 43, as illustrated in FIGS. 9-11, and the press bar 33 is pressed to descend the control bolt 34 so that the guiding channel 31 is opened to flow the tap water toward the spraying element 40 via the connector 20, then the tap water further flows to the second water supply unit 45 via the second watering path 432 of the fitting ring 43 to supply the tap water in a water shower mode, hence the tap water is collected to produce the strong washing effect, thus cleaning the residue in the water shower mode, thus cleaning the tableware or the water sink efficiently.

(20) Accordingly, the spray gun has advantages as follows:

(21) 1) The casing 60 is moved to position the spraying element 40 at the first position 4A or the second position 4B so as to switch the spray gun to supply the tap water, for example, when the tap the adjusting stem 51 is located at the first position 4A, the first water supply unit 44 supplies the tap water in the water jet mode. When the adjusting stem 51 is located at the second position 4B, the second water supply unit 45 of the spraying element 40 supplies the tap water in the water shower state, thus cleaning the kitchen effectively.

(22) 2) The spray gun is moved above to the desired washing object (such as the tableware) or place (such as the water sink) by using the length of the extending rod 23 of the connector 20, thus obtaining an outstanding cleaning effect.

(23) 3) The cap 36 is removable to clean the interior of the body 30, thus avoiding avoid the accumulation/block of incrustant.

(24) 4) To prevent a water leakage, at least one O ring is fixed on any components of the spray gun. Since the at least one O ring is a well-known art, further remarks are omitted.

(25) While the first embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. The scope of the claims should not be limited by the first embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.
