[0022] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0023] The following describes the automatic filling device for nasal sprayer provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0025] The tank binding mechanism 100 includes a base 110, and the base 110 is located at the bottom of the liquid storage tank 400. The base 110 is composed of a pad and two pads, and a sealing ring groove 120 is opened on the top of the pad, and an anti-skid pad 130 is arranged in the concave hole on the top of the pad, and a column head is arranged in the middle of the bottom surface of the base 110, and a limit sliding pad 150 is movably installed outside the limit rod 140; The liquid injection energy supply mechanism 200 includes a truss 210 installed on the base 110, and a ring rail frame 220 installed on the outer end of the truss 210; A suspension 280 is movably installed on the inner side of the ring rail frame 220, and a ring pad 290 is installed on the outer end of the suspension 280. The suspension 280 and the ring pad 290 are used to provide a lifting platform for the outer cover 310. Two cushions 230 are installed on the top of the ring rail frame 220, a vertical rod 240 is installed inside the cushion 230, and a spring 250 is arranged outside the vertical rod 240, and the suspension 280 is movably installed outside the two vertical rods 240, and the spring 250 bears pressure on the suspension 280, which is used to provide stability protection for the suspension 280 to prevent the suspension 280 from shaking during the lifting process; A motor 260 and an extension screw 270 installed on the inner shaft of the motor 260 are installed in the chassis at the bottom of the ring rail frame 220, and the suspension 280 is arranged outside the extension screw 270; The cleansing liquid filling mechanism 300 includes an outer cover 310 disposed on the top of the liquid storage tank 400, an external sterilization lamp 320 installed on the inner wall of the outer cover 310, a transfer assembly 330 disposed in the middle of the inner cavity of the outer cover 310, an anti-overflow assembly 340 disposed on the transfer assembly 330, and a sealing assembly 350 disposed on the transfer assembly 330; The transfer assembly 330 includes a reflux chamber 331 disposed in the outer housing 310 , a plurality of conduits 332 installed outside the reflux chamber 331 , and an inner housing 333 disposed at the bottom of the reflux chamber 331 ; A liquid inlet pipe 360 ​​is disposed in the sealing assembly 350, and a liquid infusion hose is connected to the top of the liquid inlet pipe 360; The overflow prevention assembly 340 includes a liquid discharge cover 341 disposed outside the reflux bin 331, and a plurality of conduits 332 are adapted to penetrate into the inner cavity of the liquid discharge cover 341; A short tube is installed at the bottom of the liquid discharge cover 341, a reinforcing mesh pad 342 is installed on the upper part of the short tube, a column 343 is installed at the lower part of the reinforcing mesh pad 342, a plug 344 is movably sleeved on the lower end of the column 343, and a tension spring 345 is also sleeved on the column 343 and located between the reinforcing mesh pad 342 and the plug 344, and the outer diameter of the plug 344 matches the inner diameter of the short tube.

[0026] When the face cleaning liquid filling mechanism 300 is lifted upward by the suspension 280 and the ring pad 290 until a sufficiently large gap is exposed between the outer cover 310 and the base 110, the liquid storage tank 400 can be placed along the pad inside the base 110. At this time, the anti-skid pad 130 provides anti-skid protection for the liquid storage tank 400, and the evenly distributed multiple limiting sliding pads 150 can be supported by elastic forces to fix and restrain the liquid storage tank 400. As the suspension 280 and the ring gasket 290 drive the outer cover 310 to slowly descend, the outer cover 310 and the combined transfer assembly 330 and the anti-overflow assembly 340 can be sealed from top to bottom along the liquid storage tank 400. At this time, the outer cover 310 is located outside the liquid storage tank 400, and the transfer assembly 330 and the anti-overflow assembly 340 extend into the interior of the liquid storage tank 400. At this time, the outer cover 310 cooperates with the base 110 to provide a sealed space for effective sterilization for the liquid storage tank 400, and the combined transfer assembly 330 and the anti-overflow assembly 340 can extend into the inner wall of the liquid storage tank 400 without contact; When physiological seawater is continuously input from the liquid inlet pipe 360, the inner cavity of the reflux chamber 331 can transfer the solution from the multiple conduits 332 to the gap between the inner cover 333 and the liquid discharge cover 341, and finally the continuously pressurized solution can squeeze the plug 344 downward, and the solution can be evenly discharged into the inner cavity of the liquid storage tank 400, accompanied by the uniform rise of the cleansing liquid filling mechanism 300 during the liquid discharge, and finally the solution filled into the liquid storage tank 400 can avoid repeated contact with the surface of the liquid discharge cover 341, while ensuring that the solution in the liquid storage tank 400 avoids overflow and reflux.

[0027] Embodiment 2: Combination Figure 1-Figure 7 As shown, on the basis of Example 1, the outer cover 310 is composed of a U-shaped cylinder, a corrugated hose and a load-bearing ring gasket, and a thickened sealing ring is provided at the bottom of the load-bearing ring gasket, and the thickened sealing ring is adapted to fit in the packaging ring groove 120.

[0028] Preferably, the two feet in the base 110 are fixed on the surface of the workbench by multiple bolts. According to the sealing requirements after the packaging ring groove 120 contacts the outer cover 310, a silicone inner pad can be provided on the inner wall of the packaging ring groove 120. As the outer cover 310 falls due to gravity and fits inside the packaging ring groove 120, the liquid storage tank 400 can be in a sealed and safe space, thereby facilitating effective sterilization.

[0029] A plurality of evenly distributed slide grooves are provided inside the pad, and a limit rod 140 is provided inside the slide groove; The limiting rod 140 is movably mounted outside thereof with a limiting sliding pad 150 and a compression spring 160 arranged outside the limiting rod 140; One end of the compression spring 160 is pressed against the inner wall of the slide groove, and the other end of the compression spring 160 is pressed against the outer wall of the limiting slide pad 150; The anti-skid pad 130 is made of thickened rubber material, and an anti-skid protrusion is provided on the top of the anti-skid pad 130; The inner wall of the limiting sliding pad 150 is provided with an anti-skid pad layer.

[0030] Preferably, an inclined surface is provided on the inner side of the top of the limiting sliding pad 150, and a rectangular slider is provided at the bottom of the limiting sliding pad 150, and the rectangular slider is movably installed on the outside of the limiting rod 140. When the liquid storage tank 400 needs to be fixed, the inclined surface on the top of the limiting sliding pad 150 can facilitate the rapid insertion of the liquid storage tank 400, and the loading and unloading of the liquid storage tank 400 can avoid being scratched.

[0031] Embodiment 3: Combination Figure 8-Figure 10 As shown, based on the embodiment 1, a cylindrical hole is opened inside the inner cover 333, and a built-in sterilization lamp holder 334 is arranged in the cylindrical hole; A wiring harness 380 is connected between the built-in sterilization lamp holder 334 and the external sterilization lamp tube 320 , and a lead is connected to the pole at the top of the wiring harness 380 .

[0032] Preferably, in the actual light-transmitting sterilization requirement, the reflux bin 331 and the inner cover 333 can be made of transparent glass, and the bottom end of the liquid inlet pipe 360 ​​extends into the bottom of the inner cavity of the reflux bin 331, and after the multiple conduits 332 evenly distributed outside the reflux bin 331 transfer the solution to the gap between the inner cover 333 and the liquid discharge cover 341, the actively transferred solution can overflow from between the plug 344 and the liquid discharge cover 341 under a continuous pressurization state, and finally the reflux of the solution in the inner cavity of the liquid storage tank 400 can be avoided; The built-in sterilizing lamp head 334 irradiates the liquid storage tank 400 in the closed cavity, and the heat released during the irradiation also evaporates the water droplets accidentally squeezed out of the outer wall of the liquid storage tank 400; A hole is provided in the short tube at the bottom of the liquid discharge cover 341, and the liquid discharge cover 341 is in the shape of a test tube as a whole; Two symmetrically distributed anti-seepage gaskets are arranged in two annular grooves on the outer wall of the plug 344 .

[0033] Preferably, a filter hole is provided inside the reinforcing mesh pad 342, and a terminal is installed at the bottom of the column 343, and the rod body of the column 343 is fixedly installed inside the reinforcing mesh pad 342; When the top end of the tension spring 345 is fixed to the bottom of the reinforcing mesh pad 342 and the bottom end of the tension spring 345 is fixed to the top of the plug 344, the plug 344 in an elastically stretched state can effectively release the solution after being pressurized, and the plug 344 will reset after the pressure is relieved, ultimately avoiding the overflow prevention component 340 from contacting the solution in the inner cavity of the liquid storage tank 400 and causing backflow.

[0034] Embodiment 4: Combination Figure 7-Figure 10 As shown, in the above embodiment, the sealing assembly 350 includes a plug 351 installed on the reflux chamber 331, two sealing rings 353 arranged in the plug 351, and a sheath 352 installed in the middle of the plug 351; The plug 351 has a vertical hole inside that is adapted to fit the liquid inlet pipe 360; The sealing assembly 350 also includes two protective housings 370 for cooperating with the wiring harness 380; The protective shell 370 is made of insulating thickened plastic, and the outer wall of the protective shell 370 is provided with a heat insulation coating.

[0035] When the plug 351 is threadedly installed on the top of the reflux chamber 331 , the neck end of the top of the outer cover 310 can be locked, and the sheath 352 arranged inside the plug 351 can provide protection for the wire harness 380 .

[0036] The working principle and use process of the present invention are as follows: the motor 260 is operated in advance, and as the rotor in the motor 260 rotates, the driven shaft will drive the extended screw 270 to rotate, and the extended screw 270 constrained by the bearing inside the ring rail frame 220 will help the suspension 280 to rise stably and at a uniform speed after rotation, and the ring pad 290 and the suspension 280 are installed outside the neck sleeve of the outer cover 310 by bolts, and the face cleaning liquid filling mechanism 300 that is actively lifted will rise vertically until a sufficiently large gap is opened between the outer cover 310 and the base 110; Then, the bottom end of the liquid storage tank 400 is inserted into the notch at the top of the base 110. At this time, the bottom of the liquid storage tank 400 is attached to the top of the anti-skid pad 130, and the multiple uniformly distributed limiting sliding pads 150 are pressed by multiple compression springs 160 to effectively fix the outer wall of the liquid storage tank 400. At this time, the top of the liquid storage tank 400 and the outer cover 310 are symmetrically distributed. Then the motor 260 is operated again. As the motor 260 is reversed, the extended screw rod 270 will help the suspension 280 and the ring gasket 290 to descend steadily. Finally, the outer cover 310 and the anti-overflow component 340 can be pressed down and adapted along the liquid storage tank 400. At this time, the bottom end of the outer cover 310 can be clamped on the inner side of the packaging ring groove 120, and the anti-overflow component 340 will penetrate into the inner cavity of the liquid storage tank 400. When the liquid storage tank 400 is sealed, the inner and outer walls of the liquid storage tank 400 will not be in contact with the outer cover 310 and the liquid discharge cover 341 and will be in a sealed environment. Then, the wire harness 380 in the energized state can transfer the current to the external sterilization lamp tube 320 and the internal sterilization lamp head 334. The external sterilization lamp tube 320 and the internal sterilization lamp head 334 that are energized and running can effectively sterilize the outer and inner walls of the liquid storage tank 400. After the inner and outer surfaces of the liquid storage tank 400 are effectively sterilized within the set time period, the wire harness 380 can be de-energized. Then, the physiological seawater is transferred to the inner cavity of the reflux chamber 331 by using the liquid inlet pipe 360. As the physiological seawater is continuously injected into the inner cavity of the reflux chamber 331, the physiological seawater will eventually flow into the gap between the inner cover 333 and the liquid discharge cover 341 along the multiple conduits 332. With the continuous increase of hydraulic pressure, the solution will eventually squeeze the plug 344 downward until the plug 344 and the short tube at the bottom of the liquid discharge cover 341 form a gap for effective liquid discharge, and the physiological seawater will flow into the inner cavity of the liquid storage tank 400 along the gap. As the liquid discharge cover 341 continuously releases the solution, the motor 260 can rotate forward during the liquid discharge period, and the cleansing liquid filling mechanism 300 as a whole will rise at a uniform speed, and finally the solution injected into the inner cavity of the liquid storage tank 400 can be filled aseptically; When the device enters the next liquid filling stage, the powered external sterilization lamp tube 320 and the internal sterilization lamp head 334 can heat-dry the solution adhered to the outer wall of the liquid discharge cover 341 and perform effective sterilization.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
