Description

Technical Field

[0001] The present invention relates to a gain type liquid supply machine, in particular to a liquid supply machine which can automatically replenish the smoke oil (smoke liquid) required for a smoke machine to generate smoke. Background Art

[0002] Supplied equipment such as smoke machines, bubble machines, snow machines, etc. will be equipped with a storage barrel for containing the liquid required for the operation of the supplied equipment. For example, the smoke machine includes a storage barrel for containing smoke water, the bubble machine includes a storage barrel for containing bubble water, and the snow machine includes a storage barrel for containing snow water.

[0003] In order to extend the operational time of the supplied equipment, there is a liquid supply device available on the market that can automatically replenish the liquid required for the operation of the supplied equipment. This liquid supply device is equipped with a liquid conveying device, a secondary storage barrel and a main storage barrel. The capacity of the main storage barrel is much larger than that of the secondary storage barrel (for example, the capacity of the main storage barrel is 20 liters, and the capacity of the secondary storage barrel is 1 liter). The liquid conveying device is arranged between the main storage barrel and the secondary storage barrel. A liquid level sensor is arranged in the secondary storage barrel. When the liquid level sensor in the secondary storage barrel detects that there is insufficient liquid in the secondary storage barrel, the liquid conveying device will operate to convey the liquid in the main storage barrel to the secondary storage barrel.

[0004] The storage barrels originally equipped with the supplied equipment such as the smoke machine, the bubble machine, the snow machine, etc. will be discarded, that is to say, a liquid delivery device included in the supplied equipment is directly connected to the auxiliary storage barrel, so that the operation of the supplied equipment is directly supplied by the auxiliary storage barrel with the liquid required to produce such as smoke, bubbles or snowflakes.

[0005] There are some problems that need to be solved in the actual use of such a configuration. First, the power of the liquid delivery device of the supplied equipment itself is set according to the length of the infusion tube from the storage barrel to the liquid delivery device of the supplied equipment. Therefore, when the storage barrel of the supplied equipment is abandoned, the length of the infusion tube required from the external auxiliary storage barrel to the liquid delivery device of the supplied equipment will be longer. If the length of the infusion tube is too long (related to the distance between the auxiliary storage barrel and the supplied equipment), the power of the liquid delivery device of the supplied equipment may be insufficient, or the supplied equipment is provided with more than one infusion tube (for example, two pipelines), which will increase the length of the infusion tube between the supplied equipment and the auxiliary storage barrel by multiples, making it difficult for the pump to extract liquid, and it is easy to cause the phenomenon of no liquid being extracted, especially if there are more than two pipelines, it is even more likely that there will be problems with installation and use.

The float 98 can be but is not limited to being composed of a hollow and sealed plastic tube, so that the float 98 has buoyancy in the liquid. The magnet 113 is attached to one end face of the coupling end 111 of the float 98. The limit cover 115 is combined with the coupling end 111 of the float 98, and the magnet 113 is limited between the limit cover 115 and the coupling end 111, so that the float 98, the magnet 113 and the limit cover 115 float together.

[0083] The floating unit 97 can be floatingly accommodated in the chamber 92 of the sleeve 86, the magnet 113 and the limit cover 115 face the extension arm 56, and the maximum length of the floating unit 97 is less than the vertical distance from the first end 88 to the counterweight block 96, so the floating unit 97 allows displacement between the counterweight block 96 and the first end 88 relative to the sleeve 86. In addition, the configuration and shape of each opening 94 avoid being completely covered by the floating unit 97, so that liquid can enter the chamber 92 from each opening 94.

[0084] The liquid supply machine 10 of the present invention is used to supply liquid required for the operation of a supplied device 35. It should be particularly noted that the supplied device 35 can be, but is not limited to, a smoke machine, a bubble machine, a snow machine, etc. The supplied device 35 is not a technical feature of the present invention. Figure 4 The supplied device 35 shown in the figure is a color-changing air column fog machine as an embodiment, and the supplied device 35 constituted by the color-changing air column fog machine includes a supplied device storage barrel 37, and Figure 6 to Figure 8 Taking only a supplied equipment storage barrel 37 included in the supplied equipment 35 as an example, the liquid level sensing device 44 of the liquid supply machine 10 of the present invention is used to combine with the supplied equipment storage barrel 37 to provide a function of detecting the liquid level height of the supplied equipment storage barrel 37.

[0085] The capacity of the supplied equipment storage barrel 37 of the supplied equipment 35 is much smaller than that of the supplementary storage barrel 20. For example, the capacity of the supplied equipment storage barrel 37 is only 1 / 5 of that of the supplementary storage barrel 20. The supplied equipment storage barrel 37 includes a space 38 and an opening locking portion 40 protrudingly formed on the outer surface of the supplied equipment storage barrel 37 and communicating with the space 38. The supplied equipment storage barrel 37 also includes a sensing through hole portion 42 extending from the surface of the supplied equipment storage barrel 37 to communicate with the space 38. It should be noted that the supplied equipment storage barrel 37 of the supplied equipment 35 generally available on the market is not provided with the sensing through hole portion 42, but the sensing through hole portion 42 can be dug when the liquid level sensing device 44 of the present invention is to be provided.

[0086] The socket portion 82 of the liquid level sensing device 44 of the present invention is sealingly socketed with the sensing through hole portion 42 of the supplied equipment storage barrel 37, and the bearing portion 80 is abutted against the surface of the supplied equipment storage barrel 37, so that the sleeve 86, the floating unit 97, and the extension arm 56 are completely located in the space 38 of the supplied equipment storage barrel 37, the locking portion 50, the mounting portion 52, the connector 74 and the signal line 70 are all located outside the space 38, and the flow channel 58 is connected to the space 38 of the supplied equipment storage barrel 37. In addition, although the sensor 68 is located inside the space 38, since the portion of the receptacle 60 located in the space 38 is the closed end 62, the sensor 68 will not come into contact with the liquid in the space 38.

[0087] The opening locking portion 40 of the supplied equipment storage barrel 37 is detachably screwed to a screw cap 43, and the screw cap 43 allows a supply pipe 39 to pass through in a sealed manner, so that one end of the supply pipe 39 is located at the bottom of the space 38, and the other end is connected to a pump included in the supplied equipment 35 (such as Figure 4 The color-changing air column smoke machine shown is provided with a pump) connection, and the supplied device 35 can extract the liquid in the space 38 from the supply pipe 39 for use (for example, to generate smoke, snowflakes or bubbles in the air).

[0088] The structural features of the present invention have been described in detail. To further understand the technical features of the present invention, please refer to Figure 6 As shown, assuming that the liquid in the space 38 of the storage barrel 37 of the supplied equipment is insufficient, the floating unit 97 of the liquid level sensing device 44 of the present invention is biased at a replenishing liquid level position (such as Figure 6 As shown), in this state, the floating unit 97 is located at the magnet 113 and does not trigger the sensor 68, so that the liquid delivery device 32 of the supply management device 26 of the present invention operates, and the liquid (such as smoke oil / smoke liquid) in the main chamber 22 of the supplementary storage barrel 20 passes through the dip tube 34, the liquid delivery device 32, and the delivery pipe 36 through the flow channel 58 into the space 38 of the storage barrel 37 of the supplied equipment.

[0089] It is worth noting that, assuming that there is no liquid in the main chamber 22 of the supplementary storage barrel 20 and the liquid in the supplied equipment storage barrel 37 is continuously used, the position of the floating unit 97 may still be lowered to rest against the counterweight block 96. In this case, the floating unit 97 is still defined as being located at the supplementary liquid level position.

[0090] When the liquid level in the space 38 rises to a level higher than the second end 90 of the sleeve 86, the liquid in the space 38 enters the chamber 92 through the openings 94, and the float 98 further moves to a high liquid level position due to the buoyancy generated by contact with the liquid. Figure 7 As shown, when the floating unit 97 moves to the high liquid level position, the limit cover 115 abuts against the bottom of the extension arm 56, so that the magnet 113 is quite close to the sensor 68 (only separated by the thickness of the limit cover 115 and the extension arm 56), and the sensor 68 is triggered by the magnetic force of the magnet 113, and transmits the signal to the supply management device 26 through the signal line 70, so that the liquid delivery device 32 stops operating. In this state, the supplied equipment storage barrel 37 has enough liquid, so that the supplied equipment 35 can continue to operate.

[0091] It is worth mentioning that the density of the counterweight block 96 is much higher than the density of the liquid. Therefore, regardless of whether the setting angle of the supplied equipment storage barrel 37 is perpendicular to the horizontal plane, due to gravity, the sleeve 86 will automatically pivot to a position perpendicular to the horizontal plane to ensure that the floating unit 97 can operate normally.

[0092] See also Figure 8 As shown, it is assumed that another type of supplied equipment 35 includes a supplied equipment storage barrel 37, and the capacity of the supplied equipment storage barrel 37 is larger. The sensing through hole portion 42 is arranged on the side of the supplied equipment storage barrel 37, so the liquid level sensing device 44 is located on the side of the supplied equipment storage barrel 37, and the extension arm 56 and the flow channel 58 of the main body 46 are substantially horizontal, but the sleeve 86 and the floating unit 97 still maintain a state substantially perpendicular to the horizontal plane.

[0093] It is worth mentioning that, since the capacity of the supplied equipment storage barrel 37 is relatively large, the liquid level sensing device 44 is configured at a position closer to the bottom of the supplied equipment storage barrel 37. Therefore, when the liquid in the supplied equipment storage barrel 37 is used up to a position closer to the bottom, the liquid delivery device 32 of the supply management device 26 starts to operate. Figure 8 From the technical features shown, it can be inferred that when the liquid level in the storage barrel 37 of the supplied equipment exceeds the first end 88 of the sleeve 86, the floating unit 97 has moved to the high liquid level position. In this state, the liquid in the storage barrel 37 of the supplied equipment may be less than half. In this state, the time for the liquid delivery device 32 to stop operating can be delayed through software or electronic control, so that the liquid in the storage barrel 37 of the supplied equipment can be replenished to a larger amount (for example, eight-tenths full).

[0094] The liquid supply machine 10 of the present invention uses the liquid level sensing device 44 to detect the liquid stock in the normal capacity storage barrel 37 of the supplied equipment. When the liquid stock in the storage barrel 37 of the supplied equipment is insufficient, the supply management device 26 automatically transfers the liquid in the supplementary storage barrel 20 to the space 38 of the storage barrel 37 of the supplied equipment, so that the supplied equipment 35 (such as a smoke machine, a snow machine, a bubble machine, etc.) can continue to operate.

[0095] The liquid supply machine 10 of the present invention directly replenishes the liquid required for operation to the supplied equipment storage barrel 37 provided in the supplied equipment 35 itself. Therefore, when there is no liquid in the replenishing storage barrel 20, since there is still liquid required for operation in the supplied equipment storage barrel 37, the supply management device 26 of the present invention and the replenishing storage barrel 20 can be directly separated, and the supply management device 26 can be quickly combined with the new replenishing storage barrel 20 (with sufficient liquid). During this process, the continuous operation of the supplied equipment 35 will not be affected, and it is very convenient to replenish liquid.

[0096] The supply management device 26 of the present invention is connected to the opening portion 24 of the replenishing storage barrel 20 through the connecting portion 30 and fixed through the main lock cover 25, and the shell 28 is against the surface of the replenishing storage barrel 20, so that the combination of the supply management device 26 and the replenishing storage barrel 20 is quite simple and quick.

[0097] The liquid level sensing device 44 of the present invention can be combined with the existing storage barrel 37 of the supplied equipment through a simple hole (sensing through hole portion 42), so that the liquid supply machine 10 of the present invention can be directly applicable to the existing commercially available supplied equipment (such as smoke machines, bubble machines, snow machines, etc.) without changing the structure of the existing supplied equipment (conventional technology).

[0098] The container is separated from the space, and the open end of the container is located outside the space, so that the sensor will not be affected by the liquid in the space, reducing the probability of damage to the liquid level sensing device 44.

[0099] The present invention supports the supply management device 26 through the support legs 29. When the liquid stock in the supplementary storage barrel 20 is small and the weight is reduced, the supplementary storage barrel 20 and the supply management device 26 will not fall over due to uneven weight distribution.

[0100] The above description is only illustrative rather than restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the claims, but all will fall within the scope of protection of the present invention.
