The liquid supply system 10 of the present invention can be used with a liquid supply device 14, and the liquid supply device 14 can supply one or more liquids required by the liquid storage device 12 and the stage device, referring to fig. 7 and 8, the liquid supply device 14 includes an input connector 273 and an output connector 275 disposed at two sides, the liquid supply device 14 further includes a pump 271 and a switch valve 279 disposed inside, the pump 271 and the switch valve 279 are connected with the input connector 273 and the output connector 275 through a plurality of internal pipelines 277, and the internal pipeline 277 is further connected with a first pressure switch 291 and a second pressure switch 292. The inlet fitting 273 of the liquid supply 14 may be connected to a liquid supply (not shown), the outlet fitting 275 may be connected to the inlet fitting 36 of at least one liquid storage device 12, and the outlet fitting 38 of the liquid storage device 12 may be connected by a conduit to a stage device, such as a smoke or snow blower … …, that operates to draw desired liquid from the liquid storage device 12 to create a stage effect, such as smoke or snow.

The purpose of the switch valve 279 is to provide a pressure adjustment function when the liquid storage device 12, the liquid supply device 14 and the stage device are installed, that is, the switch valve 279 is used to provide a pressure relief function when the installation repeatedly tests the overall pipeline balance pressure, so that the pipeline balance pressure can be repeatedly reset until the pipeline pressure reaches balance, and the switch valve 279 is closed when the pipeline pressure reaches balance, so that the liquid supply system 10 can normally operate.

It should be noted that if the liquid storage device 12 is matched with a smoking machine, the stored liquid is smoke oil or smoke water, and if the liquid storage device 12 is matched with a snowflake machine, the stored liquid is foam water. Further, the first pressure switch 291 sets the pressure higher than 3.5kg/cm²OFF, less than 2.8kg/cm²ON, thereby determining whether the system supplies liquid (e.g., foam water), it can be recognized that the first pressure switch 291 is responsible for detecting the standard pressure, which is the pressure value at which the liquid storage device 12 needs to be replenished or stops replenishing liquid through the liquid supply device 14.

The second pressure switch 292 is used to determine whether the whole pipeline has a problem of rupture or falling off (leakage will occur) the second pressure switch 292 sets the pressure higher than 2.2kg/cm²ON, less than 1.5kg/cm²When OFF, the first and second pressure switches 291, 292 control the operation or non-operation of the pump 271 by detecting the pressure in the internal line 277 in response to the software set point.

For convenience of explanation, it is assumed that a liquid supply apparatus 14 is used in conjunction with a liquid storage apparatus 12 to supply a smoking machine, and thus the liquid is smoke oil or smoke water, and further, it is assumed that the outer chamber 24 and the inner chamber 44 of the liquid storage apparatus 12 are empty, and in this state, the movable portion 213 of the valve body 199 is in the closed position (as shown in fig. 5 and 6), the main float 94 is in the low liquid level position (as shown in fig. 4), the safety float 195 is in the non-excessive liquid level position (as shown in fig. 5), and the guide float 253 is in the non-blocking position (as shown in fig. 4). In the case where the interior of the reservoir 12 is empty (as shown in FIG. 4), the first pressure switch 291 detects that the pressure in the internal line 277 is less than 2.8kg/cm²Outputting a signal to the computer of the liquid supply apparatus 14, and further controlling the pump 271 of the liquid supply apparatus 14 to operate by the outputThe inlet fitting 273 feeds the liquid from the liquid supply source to the reservoir 12 via the outlet fitting 275 by tubing.

Said liquid enters the intake unit 134 through the inlet connection 36 of the reservoir 12 and the pressure of the liquid pushes the one-way valve block 139 to move and compress the spring 151, so that the liquid is allowed to enter the connection tube 135, further the liquid pushes the movable portion 213 of the valve body 199 through the passage 131 from the closed position (shown in fig. 6) to the non-closed position (shown in fig. 9), so that the liquid can enter the first chamber 111, and further a small portion of the liquid enters the recess 61 from the channel 72 of the column 70, as shown in fig. 10, in this state, since the main float 94 is in the low liquid level position, the pressing end 86 of the secondary rocker arm 84 is far away from the through hole 74, so that the through hole 74 is not blocked by the gasket 92, so that the liquid in the recess 61 overflows from the through hole 74 into the inner chamber 44, and the liquid entering the first chamber 111 enters the second chamber 113 through the connection hole 133 (shown in fig. 10), since the safety float 195 is located at the non-excessive liquid level position, the liquid dropping plug 221 is spaced apart from the liquid dropping port 173, and the liquid in the second chamber 113 further flows through the liquid dropping port 173 into the chamber 155 of the base 153, and the liquid in the chamber 155 flows along the flow passage 157 into the outer chamber 24 of the outer barrel 20.

It is worth mentioning that, since the size of the channel 72 of the post 70 is smaller than the size of the connecting hole 133 and the liquid dropping port 173, the liquid enters the outer chamber 24 at a higher flow rate than the inner chamber 44, and since the liquid entering the recess 61 overflows from the through hole 74, the liquid pressure generated by the recess 61 is lower than the liquid pressure in the channel 131 and the first chamber 111, so that the movable portion 213 of the valve body 199 is maintained at the non-closed position.

When the liquid level in the outer chamber 24 is not high enough to displace the guide float 253 from the non-blocking position to the blocking position when the liquid enters the outer chamber 24, a small portion of the liquid entering the inner chamber 44 also enters the outer chamber 24 through the gap 56 and the opening 50 of the inner cylinder 42. When the liquid level in the outer chamber 24 rises until the guiding float 253 moves to the blocking position, the sealing member 255 of the guiding float 253 tightly abuts against the sealing surface 52 of the inner cylinder 42, so that the liquid level in the outer chamber 24 gradually rises, and when the liquid level in the outer chamber 24 rises to be higher than the flow passage 157 of the base 153, the liquid in the outer chamber 24 quickly overflows into the inner chamber 44, further causing the main float 94 to quickly rise from the low liquid level position to the high liquid level position along with the liquid level in the inner chamber 44.

Referring to fig. 12, when the liquid level in the inner chamber 44 rises to displace the main float 94 to the high level, the main rocker 76 and the secondary rocker 84 pivot to make the pressing end 86 close to the through hole 74, and the through hole 74 is further plugged by the sealing gasket 92, so that the liquid entering the recess 61 cannot escape from the through hole 74, but the liquid can still enter the recess 61 from the channel 72 of the column 70, when the liquid pressure in the recess 61 rises to be greater than the liquid pressure in the first chamber 111 and the passage 131, the movable portion 213 of the valve body 199 is pushed by the liquid pressure to displace from the non-closed position to the closed position, so that the liquid delivered from the liquid supply device 14 cannot enter the first chamber 111, in other words, the liquid cannot flow continuously only when reaching the passage 131, and the further continuously operating pump 271 makes the pressure of the inner pipeline 277 be greater than 3.5kg/cm²The computer-controlled pump 271 of the liquid supply system 14 is stopped, and referring to fig. 11, the liquid storage device 12 is in a high (full) liquid level state.

Assuming that the aerosol sprayer is operated on a stage, the pump of the aerosol sprayer is connected with the outlet connector 38 of the liquid storage device 12 through a pipeline, when the pump of the aerosol sprayer is operated, the liquid (aerosol oil/aerosol water) in the outer chamber 24 is drawn through the drainage piece 219, and along with the operation of the aerosol sprayer, the liquid level height of the outer chamber 24 gradually decreases to be incapable of supporting the guide float 253, so that the guide float 253 is displaced from the blocking position to the non-blocking position, as shown in fig. 12, the liquid originally held in the inner chamber 44 enters the outer chamber 24 through the gap 56, the opening 50 and the gap between the guide float 253 and the inner cylinder 42, and the liquid level in the outer chamber 24 is increased.

As the liquid level in the inner chamber 44 flows to the outer chamber 24 to lower the liquid level, the main float 94 loses its buoyancy support and moves from the high liquid level position to the low liquid level position, the main rocker 76 pivots under the action of the main float 94 and drives the secondary rocker 84 to pivot so that the pressing end 86 moves away from the through hole 74 (as shown in fig. 4), thereby further sealingWhen the pad 92 does not block the through hole 74, the liquid held in the chamber 61 overflows from the through hole 74, thus causing the pressure of the internal channel 277 to drop, when the first pressure switch 291 detects that the pressure of the internal channel 277 drops to 2.8kg/cm²Thereafter, the first pressure switch 291 outputs a signal to the computer of the liquid supply apparatus 14, and the computer of the liquid supply apparatus 14 controls the pump 271 to operate again to deliver liquid from the liquid supply source to the liquid storage apparatus 12 until the main float 94 is again displaced to the high liquid level position.

Assuming that the pump 271 of the liquid supply device 14 is continuously operated to continuously supply liquid into the liquid storage device 12 even though the main float 94 is located at the high liquid level position under certain conditions, as shown in fig. 13, the liquid level in the inner chamber 44 and the outer chamber 24 gradually increases, so that the safety float 195 is displaced from the non-too-high liquid level position to the too-high liquid level position by the buoyancy of the liquid and pivots the safety rocker 177, and further the safety rocker 177 displaces the liquid dropping plug 221 to plug the liquid dropping port 173, in such a state, the through hole 74 is plugged and the liquid dropping port 173 is also plugged, so that the liquid can only flow to the second chamber 113 and the concave chamber 61 and cannot continue to advance, further ensuring that the liquid level does not exceed the height of the top cover 26.

It is worth mentioning that the air vent 27 provided on the top cover 26 provides air flow when liquid enters the liquid storage device 12 or the stage device draws liquid inside the liquid storage device 12, so that the inside of the liquid storage device 12 is kept approximately equal to the external atmospheric pressure, and the air vent can operate smoothly whether liquid is delivered into the liquid storage device 12 or liquid is drawn from the liquid storage device 12.

The invention controls the opening or closing of the through hole 74 of the secondary rocker arm 84 by the linkage of the main float 94 and the main rocker arm 76, so that the pressure of the liquid in the concave chamber 61 of the liquid level controller 58 changes to control the movable part 213 of the valve body 199 to move to the closed position or the open position, thereby effectively controlling whether the liquid can enter the inner chamber 44 and the outer chamber 24.

By virtue of the safety float 195, in the over-feed state of the liquid supply apparatus 14, when the liquid level inside the liquid supply apparatus 12 displaces the safety float 195 from the non-over-high liquid level position to the over-high liquid level position, even if the pump 271 of the liquid supply apparatus 14 remains in operation, the liquid level controller 58 can prevent the liquid from continuously filling the inner chamber 44 and the outer chamber 24, so that the liquid level of the liquid supply apparatus 12 does not overflow beyond the top cover 26.

Because the liquid storage devices 12 are provided with the independent liquid level controllers 58, the single liquid supply device 14 is allowed to simultaneously supply the liquids of the plurality of liquid storage devices 12, and the plurality of liquid storage devices 12 can individually control whether the liquid supplied by the liquid supply device 14 can enter the inner accommodating chamber 44 and the outer accommodating chamber 24, so that the single liquid supply device 14 can simultaneously supply the liquids of the plurality of liquid storage devices 12, and each liquid storage device 12 can supply the liquids required by the operation of more than one stage device.

Through the arrangement of the safety float 195, the safety rocker 177, the liquid falling plug 221 and the liquid falling port 173, when the liquid level controller 58 is used for a long time and has a fault caused by foreign matters or aging, the liquid level of the outer accommodating chamber 24 is too high, the safety float 195 rises to an excessively high liquid level position, the liquid falling port 173 is plugged to prevent the liquid from continuously entering the outer accommodating chamber 24 and the inner accommodating chamber 44, the liquid can be prevented from overflowing the oil storage device 12 when the oil storage device 12 is in fault, consumer groups dropping liquid to the site can be avoided, once the safety float 195 rises, the liquid falling plug 221 and the liquid falling port 173 are plugged in a sealing mode, the phenomenon that the oil storage device 12 is in fault is represented, the oil storage device 12 cannot be opened again, the oil storage device must be detached for maintenance, and therefore the pollution to the environment and the people due to the fault of the oil storage device 12 can be avoided.

It is worth mentioning that the falling liquid plug 221 is designed like a mushroom, and the periphery of the falling liquid plug 221 is thin like a sucker, once the safety float 195 rises to an excessive liquid level position, the falling liquid plug 221 sucks the falling liquid port 173, since the falling liquid plug 221, the through hole 74 and the check valve block 139 of the check valve body 137 are all plugged, the whole liquid flow passage is fully closed, so that the first, second and third bodies 60, 98 and 171 are all filled with water, and a certain water pressure exists inside the first, second and third bodies, the safety float 195 cannot open the falling liquid plug 221 when the water level drops to a level that the safety float 195 and the main float 94 lose the buoyancy support of water, because only the tiny through hole 74 is opened, and a certain pressure still exists inside the first, second and third bodies 60, 98 and 171, so that the weight of the safety float 195 is not enough to resist the suction force of the falling liquid plug 221, therefore, the liquid dropping plug 221 keeps closing the liquid dropping port 173, and the liquid connected to the outside through the inlet joint 36 cannot enter the liquid level controller 58 even by the pressure existing inside the first, second, and third bodies 60, 98, 171, so that it is difficult to continue the water storage even if a very small amount of liquid flows into the through hole 74. Therefore, the liquid storage device 12 can be found to be in fault by related personnel in a liquid leakage-free state, and further the personnel can repair the fault liquid storage device 12.

The design of the inner and

outer chambers

44, 24 in cooperation with the guide float 253 of the present invention enables the liquid to enter the inner chamber 44 and remain in the inner chamber 44 after the liquid level overflows the flow channel 157, so that the main float 94 does not displace between a position close to a high liquid level (liquid is supplied to the liquid supply device 14) and a position close to the high liquid level (liquid is not supplied to the liquid supply device 14), and the problem of repeated start and stop of the pump 271 of the liquid supply device 14 in a short time can be solved.

While the basic teachings of the present invention have been described, numerous extensions and variations will be apparent to those of ordinary skill in the art. For example, the liquid storage device 12 is not limited to the liquid supply device 14 shown in the drawings and described in the specification, and the liquid storage device 12 can be matched with other types of liquid supply devices 14. Alternatively, the liquid supply system 10 of the present invention is not limited to use with aerosol and snow flakes machines.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
