Description

Technical Field

[0001] This utility model relates to the field of bathroom fixtures technology, and in particular to a spray gun water outlet device with a built-in pure water supply channel. Background Technology

[0002] Existing faucets, showerheads, or spray guns typically have one outlet for tap water. However, in many cases, a water purifier faucet is also needed near these devices to provide purified water. These two independently installed water devices take up considerable space and are inconvenient to operate, use, and clean, making them less practical.

[0003] To address this issue, a combined water outlet device has been designed, integrating both tap water and purified water outlets for ease of use. However, the existing water circuit control switch structure of this combined device is relatively complex, and the operation of the outlet switching switch is inconvenient, requiring improvement. Utility Model Content

[0004] To address the aforementioned issues, the present invention aims to provide a spray gun water outlet device with a built-in pure water supply channel, which integrates pure water and tap water outlets. The tap water outlet section has two independent water passages, one of which can be independently switched on and off within the device, facilitating the output of two different water effects and making it convenient to use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spray gun with a built-in pure water supply channel includes a cylinder, a tap water pipe connector, and a pure water pipe connector. The tap water pipe connector is sleeved in the cylinder, and the pure water pipe connector is sleeved in the tap water pipe connector. The tap water pipe connector and the pure water pipe connector are coaxially connected in a water distribution body. The water distribution body is provided with a connecting sleeve and a connecting ring seat. The pure water pipe connector is inserted into the connecting sleeve. The connecting ring seat is connected to a tap water distribution mechanism. The tap water distribution mechanism has two independent water passages connected to the tap water pipe connector. The first water passage is normally open, and the second water passage can be rotatably opened or closed. The outlet cover connected to the output ends of the two water passages is located in the cylinder on the output side of the water distribution body. The center of the outlet cover is provided with a pure water outlet pipe corresponding to and connected to the pure water pipe connector.

[0007] Furthermore, the tap water dispensing mechanism includes a water dispensing ring, a water sealing plate, and a water dispensing switching plate. The water dispensing ring has a central connecting pipe, a first water passage, and a second water passage. The two ends of the central connecting pipe are respectively connected to a pure water pipe connector and a pure water outlet pipe. The water outlet cover has a first water outlet mesh plate and a second water outlet ring groove. The first water outlet mesh plate and the first water passage are normally open and connected. The water dispensing switching plate is sleeved on the connecting ring seat. The water dispensing ring, the water sealing plate, and the water outlet cover are located inside the cylinder and can rotate coaxially with respect to the water dispensing switching plate. When the water dispensing ring rotates, it controls the opening or closing of the second water passage. When it is open, water flows out from the second water outlet ring groove.

[0008] Furthermore, the water outlet cover and the water distribution ring are coaxially arranged in the cylinder body, and the water sealing plate is arranged in the water distribution ring. The water sealing plate is provided with a central through hole, a first water through hole and a second water through hole corresponding to the central connecting pipe, the first water through channel and the second water through channel respectively. The cylinder body drives the water distribution ring, the water sealing plate and the water outlet cover to rotate together relative to the water distribution switching plate to realize the opening or closing of the second water passage.

[0009] Furthermore, the water distribution switching plate is axially and vertically fitted into the connecting ring on the connecting ring seat. The water distribution switching plate is provided with a central sleeve and a water passage notch, and the central connecting pipe passes through the central sleeve.

[0010] Furthermore, the outer cylinder of the central sleeve is provided with a guide bar, and the connecting ring is provided with a guide groove to guide the guide bar to slide up and down.

[0011] Furthermore, the water-dividing ring sleeve is provided with a guide inclined block corresponding to the position of the water passage gap, and a compression spring is provided between the connecting ring seat and the water-dividing switching plate; when the water-dividing ring sleeve rotates, it pushes the water-dividing switching plate to rise and fall along the axial direction of the guide inclined block.

[0012] Furthermore, the water-dividing switching plate is provided with a stop block to limit the end of the compression spring.

[0013] Furthermore, the water distribution body is provided with a rotation limiting groove, and the water distribution ring is provided with a corresponding rotation limiting protrusion.

[0014] Furthermore, the input end of the water distribution body is connected to a fixed connection joint.

[0015] This utility model has the following beneficial effects:

[0016] This invention features an independent purified water pipe and a tap water distribution mechanism. The purified water pipe is installed in the outlet cover connecting two tap water output channels. The on / off switch of the purified water pipe is controlled by an external switch, and one of the two tap water output channels can be operated independently, facilitating the output of two different tap water effects and making it convenient to use.

[0017] The water distribution mechanism of this utility model is equipped with a water distribution ring, a water sealing plate, and a water distribution switching plate. The water distribution ring, the water sealing plate, and the water outlet cover are located inside the cylinder and can rotate coaxially with respect to the water distribution switching plate. When the water distribution ring rotates, it controls the opening or closing of the second water passage. When it is opened, water flows out from the second water outlet ring groove, forming two water outlet effects with the water flowing out from the normally open first water outlet mesh plate. Its structure is unique and ingenious.

[0018] The water outlet cover and the water distribution ring are coaxially arranged inside the cylinder. By rotating the cylinder, the water distribution ring, the water sealing plate and the water outlet cover can be rotated to open or close the second water passage. The overall structure is compact and easy to operate. Attached Figure Description

The first water passage is normally open, and the second water passage can be rotated to open or close. The water outlet cover 6 connected to the output end of the two water passages is located in the cylinder 1 on the output side of the water dispensing body 4. The center of the water outlet cover 6 is provided with a pure water outlet pipe 61 that is connected to the pure water pipe connector 3. A protective net can be installed in the pure water outlet pipe 61.

[0033] The tap water distribution mechanism 5 includes a water distribution ring 51, a water sealing plate 52, and a water distribution switching plate 53. The water distribution ring 51 is provided with a central connecting pipe 511, a first water passage 512, and a second water passage 513. The two ends of the central connecting pipe 511 are respectively connected to a pure water pipe connector 3 and a pure water outlet pipe 61. The water outlet cover 6 is provided with a first water outlet screen plate 62 and a second water outlet ring groove 63. A filter screen is provided in the cavity of the water outlet cover 6. The first water outlet screen plate 62 and the first water passage 512 are respectively... Normally open and connected, the water distribution switching plate 53 is sleeved on the connecting ring seat 42. The water distribution ring sleeve 51, the water sealing plate 52, and the water outlet cover 6 are located inside the cylinder 1 and can rotate coaxially relative to the water distribution switching plate 53. The outer ring of the water distribution ring sleeve 51 is provided with a connecting thread that connects to the cylinder 1. The water distribution body 4, the cylinder 1, the water distribution ring sleeve 51, and the water outlet cover 6 are provided with a leak-proof sealing ring at the connection points. The water distribution body 4 is provided with a rotation limiting groove 43, and the water distribution ring sleeve 51 is provided with a corresponding rotation limiting protrusion 515. When the water distribution ring sleeve 51 rotates, it controls the opening or closing of the second water passage 513. When opened, water flows out from the second water outlet ring groove 63. The water outlet cover 6 and the water distribution ring 51 are coaxially arranged inside the cylinder 1. The water sealing plate 52 is disposed in the water distribution ring 51. The water sealing plate 52 has a central through hole 521, a first water through hole 522, and a second water through hole 523 corresponding to the central connecting pipe 511, the first water through channel 512, and the second water through channel 513, respectively. The cylinder 1 drives the water distribution ring 51, the water sealing plate 52, and the water outlet cover 6 to rotate together relative to the water distribution switching plate 53 to open or close the second water passage. The water distribution switching plate 53 is axially and vertically fitted into the connecting ring 421 on the connecting ring seat 42. The water distribution switching plate 53 has a central sleeve 531 and a water through notch 532. The central connecting pipe 511 passes through the central sleeve 531.

The compression spring 54 is used to push the water-dividing switching plate 53 down to block the second water passage 523 and close the second water passage. When the water-dividing ring sleeve 51 rotates, it pushes the water-dividing switching plate 53 to overcome the pressure of the compression spring 54 and rise axially along the guide inclined block 514. After the water-dividing switching plate 53 rises, it no longer blocks the second water passage 523, and the water flows through the second water passage 523 and the second water passage 513 to the second water outlet ring groove 63 and out. The water-dividing switching plate 53 is provided with a stop block 534 to limit the end of the compression spring 54.

[0034] In use, the water outlet of this spray gun connects to the water outlet of a faucet with an internal purified water pipe. The faucet contains a main switch and a separate purified water switch. When purified water is needed, turning on the purified water switch will output purified water from the purified water outlet pipe 61. See the water outlet diagram. Figure 3 When the main switch in the faucet is turned on (the second water passage is closed by default), water flows directly from the holes of the first water outlet screen 62 through the first water passage, which is the shower head output mode. See the water outlet diagram. Figure 4 Then rotate cylinder 1 to open the second water passage. The second water flows out from the second outlet annular groove 63. The water droplets from the two outlets collide to form icicles. See the water outlet diagram. Figure 5 .
