Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, and in particular to a spraying device for an odorless liquid flame retardant. Background Technology

[0002] Odorless liquid flame retardants are liquid flame retardants that have no obvious odor at room temperature or during use. They mainly achieve flame retardant effects through chemical inhibition or physical isolation. Odorless liquid flame retardants need to be sprayed in a wide area using a spraying device during use.

[0003] Existing odorless liquid flame retardant spraying devices require selecting the appropriate spray head based on spraying needs. However, when different spray heads are needed during spraying, the currently used spray head must be disassembled and replaced with a new one, which is cumbersome and time-consuming. Therefore, there is a need for an odorless liquid flame retardant spraying device. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an odorless liquid flame retardant spraying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an odorless liquid flame retardant spraying device, comprising a movable base, a storage tank and a handrail installed on the top of the movable base, an input end of a diaphragm pump fixedly connected to the output end of the storage tank, a fixed seat installed on the top of the movable base, and the diaphragm pump installed on the top of the fixed seat, a connecting pipe fixedly connected to the output end of the diaphragm pump, a delivery pipe fixedly connected to the output end of the connecting pipe, an outlet pipe rotatably connected to the top of the delivery pipe, a fixing ring fixedly connected to the inner side wall of the outlet pipe, an outlet hole opened inside the fixing ring, a nozzle seat rotatably connected to the end of the outlet pipe, a partition plate fixedly connected inside the nozzle seat, a nozzle assembly fixedly connected inside the nozzle seat, the nozzle assembly including a first nozzle, a second nozzle and a third nozzle, a limiting component installed at the bottom of the outlet pipe, and the limiting component corresponding to the position of the nozzle seat.

[0006] Furthermore, a limiting block is fixedly connected to the bottom of the nozzle holder, and a limiting groove is formed inside the limiting block.

[0007] Furthermore: a fixing block is fixedly connected to the bottom of the liquid outlet pipe, and a sliding rod is slidably connected inside the fixing block. The end of the sliding rod away from the fixing block is inserted into the inside of the limiting groove.

[0008] Furthermore, a first limiting ring and a second limiting ring are fixedly connected to the circumferential surface of the slide rod. The first limiting ring is in contact with the side surface of the fixing block, and the second limiting ring is in contact with the side surface of the limiting block.

[0009] Furthermore, a compression spring is sleeved on the outside of the slide rod, and the compression spring is located between the second limiting ring and the fixing block.

[0010] Furthermore: a mounting bracket is fixedly connected to the top of the movable base, and the infusion tube is located inside the mounting bracket. A fixing bracket is fixedly connected to the side surface of the mounting bracket. A motor is installed inside the fixing bracket. A rotating shaft is fixedly connected to the output end of the motor. A second gear is fixedly connected to the top of the rotating shaft. A first gear is fixedly connected to the circumferential surface of the infusion tube, and the first gear meshes with the outer surface of the second gear.

[0011] This utility model has the following beneficial effects: Compared with existing technologies, this odorless liquid flame retardant spraying device, by setting a fixing ring, a liquid outlet, a nozzle seat, and a partition plate, allows the partition plate to rotate inside the liquid outlet pipe when the device is in use. This makes the liquid outlet inside the fixing ring correspond to different nozzles inside the nozzle assembly, and the nozzle seat is limited by a limiting component. This allows the device to switch between different nozzles without disassembly, which improves the ease of use of the device.

[0012] Compared with existing technologies, this odorless liquid flame retardant spraying device, by setting a first gear and a second gear, starts the motor when the device is in use, and uses the motor to drive the rotating shaft to rotate. During the rotation of the rotating shaft, the second gear drives the first gear to rotate, thereby driving the liquid outlet pipe to adjust the angle, which helps to expand the spraying range of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1-6 This utility model provides an odorless liquid flame retardant spraying device, comprising a movable base 1, a storage tank 2 and a handle 7 mounted on the top of the movable base 1, an input end of a diaphragm pump 4 fixedly connected to the output end of the storage tank 2, a fixed base 3 mounted on the top of the movable base 1, and the diaphragm pump 4 mounted on the top of the fixed base 3, a connecting pipe 5 fixedly connected to the output end of the diaphragm pump 4, an infusion pipe 8 fixedly connected to the output end of the connecting pipe 5, and an outlet pipe 14 rotatably connected to the top of the infusion pipe 8. A fixing ring 15 is fixedly connected to the inner wall of the outlet pipe 14. An outlet hole 16 is provided inside the fixing ring 15. A nozzle seat 17 is rotatably connected to the end of the outlet pipe 14. A partition plate 18 is fixedly connected inside the nozzle seat 17, and a nozzle assembly 19 is fixedly connected inside the nozzle seat 17. The nozzle assembly 19 includes a first nozzle 1901, a second nozzle 1902, and a third nozzle 1903. A limiting component 20 is installed at the bottom of the outlet pipe 14, and the limiting component 20 corresponds to the position of the nozzle seat 17. During use, the nozzle seat 17 drives the partition plate 18 to rotate inside the outlet pipe 14, causing the outlet hole 16 inside the fixing ring 15 to correspond to different nozzles inside the nozzle assembly 19. The limiting component 20 limits the nozzle seat 17, allowing for switching between different nozzles without disassembly, thus improving the ease of use of the device.

[0017] A limiting block 2001 is fixedly connected to the bottom of the nozzle holder 17, and a limiting groove 2002 is formed inside the limiting block 2001. There are three limiting blocks 2001, each corresponding to a different nozzle.

[0018] A fixing block 2003 is fixedly connected to the bottom of the liquid outlet pipe 14. A sliding rod 2004 is slidably connected inside the fixing block 2003. The end of the sliding rod 2004 away from the fixing block 2003 is inserted into the interior of the limiting groove 2002. The sliding rod 2004 moves within the fixing block 2003.

[0019] A first limiting ring 2005 and a second limiting ring 2006 are fixedly connected to the circumferential surface of the slide rod 2004. The first limiting ring 2005 is in contact with the side surface of the fixing block 2003, and the second limiting ring 2006 is in contact with the side surface of the limiting block 2001. The first limiting ring 2005 and the second limiting ring 2006 are used to limit the displacement of the slide rod 2004.

[0020] A compression spring 2007 is sleeved on the outside of the slide rod 2004, and the compression spring 2007 is located between the second limiting ring 2006 and the fixing block 2003. The compression spring 2007 constantly pushes the second limiting ring 2006 through its reaction force, so that the slide rod 2004 is engaged with the inside of the limiting groove 2002, and through its connection with different limiting blocks 2001, it achieves the limitation of the nozzle seat 17.

[0021] A mounting bracket 6 is fixedly connected to the top of the mobile base 1, and the infusion tube 8 is located inside the mounting bracket 6. A fixing bracket 10 is fixedly connected to the side surface of the mounting bracket 6. A motor 11 is installed inside the fixing bracket 10. A rotating shaft 12 is fixedly connected to the output end of the motor 11. A second gear 13 is fixedly connected to the top of the rotating shaft 12. A first gear 9 is fixedly connected to the circumferential surface of the infusion tube 14, and the first gear 9 meshes with the outer surface of the second gear 13. When the device is in use, the motor 11 is started, which drives the rotating shaft 12 to rotate. During the rotation of the rotating shaft 12, the second gear 13 drives the first gear 9 to rotate, thereby driving the infusion tube 14 to adjust its angle, which helps to expand the spraying range of the device.

[0022] Working principle: When the device is in use, the odorless liquid flame retardant inside the storage tank 2 is pumped by the diaphragm pump 4 through the connecting pipe 5 and the delivery pipe 6 into the outlet pipe 14, and then into the nozzle seat 17 through the outlet hole 16. Finally, it is discharged from the nozzle assembly 19 for spraying. When the nozzle needs to be changed, the nozzle seat 17 drives the partition plate 18 to rotate inside the outlet pipe 14, so that the outlet hole 16 inside the fixing ring 15 corresponds to the different nozzles inside the nozzle assembly 19. The limiting component 20 limits the nozzle seat 17, so that the device can switch between different nozzles without disassembly, which improves the convenience of the device. When the device is in use, the motor 11 is started, which drives the rotating shaft 12 to rotate. During the rotation of the rotating shaft 12, the second gear 13 drives the first gear 9 to rotate, which in turn drives the outlet pipe 14 to adjust the angle, which helps to expand the spraying range of the device.
