[0030] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0031] like Figure 1-11As shown, a dual-function spray gun includes a housing 1, an adapter pipe 2, and a switching valve seat. The front end of the housing 1 is provided with a spray nozzle 11, and the side of the housing 1 is provided with a spray surface 12. The spray surface 12 is provided with a plurality of spray nozzles 13. The switching valve seat is located inside the housing 1 and is connected to the spray nozzles 11 and 13. The adapter pipe 2 is inserted inside the housing 1 and the front end of the adapter pipe 2 is connected to the switching valve seat. The rear end of the adapter pipe 2 is connected to a water supply pipe. The switching valve seat is provided with a push button 7. By moving the push button 7, the water output from the spray nozzle 11 or the spray nozzle 13 can be switched.
[0032] In this embodiment, the switching valve seat includes a base 3, a valve body 4, and a valve core 5. The base 3 is installed on the spray surface 12, and the valve body 4 is located on the upper end of the base 3 and installed inside the outer casing 1. The gap between the valve body 4 and the base 3 forms a spray channel 61. The side wall of the valve body 4 is provided with a first switching port 41, a second switching port 42, and a guide port 43. The front end of the valve body 4 is provided with a spray channel 62 that communicates with the spray nozzle 11. Specifically, the front end of the valve body 4 is provided with a water outlet pipe 44, the front end of which is inserted into the spray nozzle 11 to position the valve body 4. The spray channel 62 is located inside the spray pipe, and the diameter of the spray channel 62 gradually decreases from back to front, thereby increasing the pressure of the water flow sprayed out of the spray channel 62. The adapter pipe 2 is connected to the valve body 4. The adapter pipe 2 is provided with a first water inlet 21 and a second water inlet 22. The first water inlet 21, the first switching port 41, the guide port 43, and the spray channel 62 are connected in sequence. The second water inlet 22, the second switching port 42, and the spray channel 61 are connected in sequence. The valve core 5 is rotatably connected inside the adapter pipe 2, and a sealing ring is provided on the outside of the valve core 5 to prevent leakage. The valve core 5 has a water outlet 51 on its side wall. By rotating the valve core 5, the orientation of the water outlet 51 is controlled. When the water outlet 51 is connected to the first water inlet 21, water flows sequentially through the first water inlet 21, the first switching port 41, the guide port 43, and the spray channel 62, thereby forming a high-pressure water flow and finally spraying it out from the spray nozzle 11. When the water outlet 51 is connected to the second water inlet 22, the water flows through the second water inlet 22, the second switching port 42 and the water spray channel 61 in sequence, and finally flows out from each water spray nozzle 13.
[0033] In this embodiment, the water nozzle 13 is located on the base 3. The upper end of the base 3 is provided with a mounting groove 31, and the valve body 4 is embedded in the mounting groove 31. The remaining space in the mounting groove 31 is the water flow channel 61. A mounting plate 32 is also embedded in the mounting groove 31. The mounting plate 32 is provided with a plurality of nozzles 33, which extend through the water nozzle 13 to the outside of the base 3. Different numbers of nozzles 33 can be installed on the mounting plate 32. The corresponding mounting plate 32 can be selected and replaced according to the needs to change the number of nozzles 33, thereby meeting the requirements for water flow rate and water area 12.
[0034] In this embodiment, to facilitate the installation of the push button 7, improve the structural strength of the push button 7, and extend the service life of the valve core 5, a fixing member 8 is fitted onto the front end of the valve core 5. The fixing member 8 includes a ring 81 and an arc-shaped positioning part 82 connected to the outside of the ring 81. The front end of the valve core 5 has a first slot 52, the ring 81 has a second slot 811, and the arc-shaped positioning part 82 has a third slot 821. The lower end of the push button 7 has a connecting rod 71, which is inserted into the first slot 52, the second slot 811, and the third slot 821 for fixation. Furthermore, the side wall of the connecting rod 71 has a limiting protrusion 72, and a limiting groove 83 is provided between the ring 81 and the arc-shaped positioning part 82 for the limiting protrusion 72 to engage. Through the engagement of the limiting protrusion 72 and the limiting groove 83, the connecting rod 71 can be fixedly connected to the valve core 5 and the fixing member 8. Furthermore, the sidewall of the lower protrusion gradually slopes inward from top to bottom, and the sidewall of the third slot 821 gradually slopes inward from top to bottom, serving as a guide and facilitating the insertion of the limiting protrusion 72 into the limiting slot 83.
[0035] In this embodiment, a first clearance hole 14 is provided on the outer shell 1, a second clearance hole 45 is provided on the side wall of the valve body 4, and a third clearance hole 23 is provided on the side wall of the adapter pipe 2. The second clearance hole 45 is correspondingly located below the first clearance hole 14, and the third clearance hole 23 is correspondingly located below the second clearance hole 45. The first clearance hole 14, the second clearance hole 45, and the third clearance hole 23 are used to provide clearance when the connecting rod 71 swings. Furthermore, a positioning boss 46 is provided inside the valve body 4. The positioning boss 46 can abut against both ends of the arc-shaped positioning part 82 to play the role of limiting and positioning.
[0036] More specifically, to facilitate the assembly and disassembly of the adapter tube 2 and the outer casing 1, a retaining ring 9 is fitted at the rear end of the adapter tube 2, and a counter-receiving frustum 24 abuts against the retaining ring 9 at the rear end of the adapter tube 2. A retaining strip 91 is fitted on the side wall of the retaining ring 9, and a retaining groove 15 that mates with the retaining strip 91 is provided on the inner side wall of the outer casing 1. With the above structure, after inserting the adapter tube 2 into the outer casing 1, the retaining ring 9 is fitted onto the end of the adapter tube 2, and then the retaining ring 9 is rotated to engage the retaining strip 91 with the retaining groove 15, thus fixing the adapter tube 2 inside the outer casing 1, making the assembly and disassembly of the adapter tube 2 more convenient and quick. Furthermore, a positioning protrusion 25 is provided on the side wall of the adapter tube 2, and a positioning groove 16 that mates with the positioning protrusion 25 is provided on the inner side wall of the outer casing 1. Through the engagement of the positioning protrusion 25 and the positioning groove 16, the orientation of the adapter tube 2 can be positioned, while preventing the adapter tube 2 from rotating or shifting within the outer casing 1.
[0037] The working principle of this utility model is as follows: When the push button 7 is pushed to the right, the water outlet 51 on the valve core 5 connects with the first water inlet 21. At this time, water flows sequentially through the first water inlet 21, the first switching port 41, the guide port 43, and the spray channel 62, thereby forming a high-pressure water flow and finally spraying out from the spray nozzle 11. When the push button 7 is pushed to the left, the water outlet 51 on the valve core 5 connects with the second water inlet 22. At this time, water flows sequentially through the second water inlet 22, the second switching port 42, and the spray channel 61, and finally flows out from each spray nozzle 13.
[0038] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
