Background

The solid carbon dioxide called dry ice has the characteristic that the solid carbon dioxide can be directly sublimated into gas state to generate smoke effect when being heated, and a tunnel owner designs a dry ice smoke machine according to the characteristic of the dry ice, and the dry ice smoke machine controls the amount and the time of the smoke generated by the dry ice in a mechanical mode. Traditional dry ice aerosol sprayer usually sets up a waterlogging caused by excessive rainfall basket that has a plurality of holes in inside, the inside dry ice that places of waterlogging caused by excessive rainfall basket, and hot water has been held to waterlogging caused by excessive rainfall basket below, when dry ice aerosol sprayer does not produce smog, the waterlogging caused by excessive rainfall basket is located the position that the hot water of dry ice and below separates, a plurality of ice aerosol sprayers will produce smog, the position that the orientation that is close to hot water of system drive waterlogging caused by excessive rainfall basket removes to dry ice and hot water contact, so dry ice will sublimate into the gaseous state because of the absorbed heat and produce a large amount of smog, dry ice aerosol sprayer is with these smog again derive the.

In the operation mode of the conventional dry ice smoking machine (the draining basket moves to soak the dry ice in hot water), the dry ice is soaked in the hot water, so that the dry ice is not separated from the hot water, and the heat preservation effect is poor, so that the dry ice is usually stored in an insulation box independent of the outer side of the dry ice smoking machine, when the dry ice needs to be used, the dry ice is further placed into the dry ice smoking machine from the position taken from the insulation box, the use mode is inconvenient, and the storage time of the dry ice is reduced due to the temperature of the heated water in the use process. For example, on the stage where the dry ice fog machine is frequently used, since the dry ice fog machine has no or poor heat preservation effect, the dry ice is continuously consumed even if the dry ice is not used, and if the stage performance time is long, the situation that the time for generating the smoke is needed but the dry ice in the dry ice fog machine is completely consumed or is insufficient may be encountered, and the dry ice in the dry ice fog machine is not suitable to be supplemented during the stage performance time.

Furthermore, because the conventional dry ice smoking machine operates in a manner that the draining basket moves to immerse the dry ice in the hot water, which results in the dry ice smoking machine having a volume at least twice as large as its dry ice capacity (so that the dry ice can be completely immersed in the water), most of the commercially available dry ice smoking machines have a small dry ice capacity, so that the single dry ice smoking machine can generate a small amount of smoke and the time for generating the smoke is not long enough.

The drain basket 42 may be provided to contain at least one dry ice 80.

As shown in the drawings, the aerosol sprayer 10 further includes a water pumping device 60 and a heating device 66, wherein the water pumping device 60 is fixed in the third chamber 28, the water pumping device 60 is formed by a water pumping motor, the water pumping device 60 further includes a water inlet 62 located in the second chamber 26 and a water spraying 64 located in the first chamber 24, and when the water pumping device 60 is operated, the water in the second chamber 26 can be delivered to the first chamber 24.

The heating device 66 is disposed on the housing 20, and the heating device 66 includes a heater 68 disposed at the bottom of the second chamber 26, and the heater 68 can heat the water contained in the second chamber 26 to raise the temperature.

A side cover 72 is fixedly arranged on the surface of the housing 20 and at a position corresponding to the third accommodating chamber 28, the third accommodating chamber 28 is covered by the side cover 72, a cover 70 is pivoted at the opening of the first accommodating chamber 24 above the housing 20, and the first accommodating chamber 24 is closed when the cover 70 is closed.

The aerosol sprayer 10 further includes a lid 74, and the lid 74 includes a front opening 77 corresponding to the aerosol outlet 21 and a lower opening 76 corresponding to the second compartment 26. The partition cover 74 is disposed between the smoke outlet 21 and the peripheral wall 30 and one end of the front opening 77 is accommodated in the smoke outlet 21, the lower opening 76 of the partition cover 74 facing the heater 68 of the second accommodating chamber 26.

For convenience of explanation, it is assumed that 8 dry ice pieces 80 are placed in the drip basket 42 and that the second compartment 26 contains an appropriate amount of water 82, the heater 68 of the high-intensity curtain heating device 66 of water 82. When the aerosolizer 10 is not in operation, the water 82 is at substantially ambient temperature, and the dry ice 80 is separated from the water 82 by the spacer 38, further the dry ice 80 may be better preserved when the aerosolizer 10 is not in operation.

Referring to fig. 7 to 8, when smoke is to be generated, the heater 68 of the heating device 66 heats the water 82 to raise the temperature, the water pumping device 60 sucks the water with raised temperature from the water inlet 62 and discharges the water from the water spraying 64, so that the water level in the first chamber 24 rises, when the water 82 with higher temperature in the first chamber 24 rises and enters the draining basket 42 from the water outlets 44 and contacts the dry ice 80, the dry ice 80 absorbs the heat of the water and is gasified into smoke, when the pressure in the first chamber 24 is higher than the pressure in the second chamber 26 and the weight of the smoke exhaust valve 50 when the smoke fills the first chamber 24, the smoke exhaust fog valve 50 in the first chamber 24 pushes away the water 82 in the remaining space in the second chamber 26 through the through hole 48A and the smoke exhaust port 32,

it should be mentioned that, because of the isolation cover 74, the smoke emitted from the first accommodating chamber 24 cannot be directly ejected from the smoke outlet 21, because the lower opening 76 of the isolation cover 74 is separated from the smoke outlet 32, the smoke emitted from the first accommodating chamber 24 can be ejected from the lower opening 76 of the isolation cover 74 through the front opening 77 and the smoke outlet 21 after being diffused to the second accommodating chamber 26, and such a design has the advantage that the water gas generated by the water 82 with high temperature in the first accommodating chamber 24 is not easily taken out of the first accommodating chamber 24 along with the smoke, and thus the smoke ejected from the smoke outlet 21 is dry. Furthermore, the blocking portion 47 of the overflow preventing element 46 can prevent water, water splash or moisture introduced into the first chamber 24 from overflowing from the through hole 48A and the smoke outlet 32.

In addition, when the water level in the first chamber 24 and the water in the first chamber 24 enter the enclosing wall 41 through the holes 43 of the enclosing wall 41, the pressure of the water will increase the pressure borne by the cover 56, and when the pressure borne by the cover 56 exceeds the load of the supporting spring 58, the cover 56 will move from the second position closing the drainage opening 40 to the first position opening the drainage opening 40, so that the water injected into the first chamber 24 can flow back into the second chamber 26 through the through hole 36 via the drainage opening 40, so that the water 82 with the decreased temperature can be heated again.

The utility model discloses dry ice fog machine 10 utilizes pumping device 60 to hold room 26 water 82 with the second and carries toward first room 24 to cooperation drainage mechanism 52 makes the water in first room 24 can flow back to second room 26, can be under the state of unmoving dry ice 80, make dry ice 80 can be continuous contact temperature higher water 82 and the heat gasification that absorbs water 82 becomes gas production smog effect effectively, compare in prior art under the condition of the same volume at fog machine 10, can hold more dry ice 80 (because the space that provides some spaces that drain basket and dry ice displacement soak into water originally and the mechanism that the holding provided drain basket and dry ice removal can be used for placing great drain basket and extra dry ice), further prolong the time that fog machine 10 can produce smog (the running time of dry ice fog machine increases).

Because waterlogging caused by excessive rainfall basket 42 and dry ice 80 need not remove, can not consider the heavy burden problem of removing dry ice 80 during consequently aerosol sprayer 10 design, even heavy burden increase is led to waterlogging caused by excessive rainfall basket 42 enlarging, does not have direct influence to the operation of whole aerosol sprayer 10, further allows the increase of aerosol sprayer's volume for hold more dry ice inside aerosol sprayer, further can prolong aerosol sprayer's operating time effectively.

Another benefit of aerosol sprayer 10 of the present invention is that spacer 38 is disposed between first and

second chambers

24, 26, and heat insulating layer 38A of spacer 38 can reduce the temperature of water 82 and transmit the efficiency to first chamber 24, further effectively prolonging the storage time of dry ice 80 in first chamber 24.

The lower opening 76 of the isolation cover 74 is disposed toward the heater 68, so that the moisture generated from the water 82 with high temperature in the first chamber 24 is not easily carried out of the first chamber 24 along with the smoke, and the smoke emitted from the smoke outlet 21 is relatively dry.

By the arrangement of the overflow-preventing element 46, the probability that the moisture in the first accommodating chamber 24 can pass through the smoke outlet 32 can be effectively reduced, and the probability that the moisture can drip from the smoke outlet 21 can be reduced by matching with the isolating cover 74.

The inclined bottom wall 34 is provided so as to be inclined such that the drain opening 40 is provided at the lowest position in the height direction of the bottom wall 34, and the water 82 in the first chamber 24 can be smoothly discharged from the drain opening 40 into the second chamber 26.

The basic teachings of the invention have been described, and many extensions and variations will be apparent to those having ordinary skill in the art. For example, aerosol sprayer 10 may not include drip basket 42, such that the at least one dry ice 80 may still be contained within first compartment 24 and may be vaporized directly to produce the aerosol upon contact with the hot water.
