Description

dry ice fog machine

The invention relates to a dry ice cloud fog machine, in particular to a dry ice cloud fog machine that can be applied to a stage to generate cloud fog effects.

Dry ice is solid carbon dioxide that sublimates directly to a gaseous state when heated. Therefore, dry ice is often used on the stage to create a cloudy effect. The operating principle of the existing dry ice machine is to control the amount and timing of the water mist generated by the dry ice through the water pump. In detail, the existing dry ice machine includes a housing, a hot water tank in fluid communication with the interior of the housing, a water pump, and a container with a drain hole for placing dry ice. After the container is loaded with dry ice, it can be placed inside the housing.

When the dry ice machine operates to generate water mist, the water pump draws the hot water in the hot water tank into the housing, so that the hot water contacts the dry ice in the container. In this way, the dry ice will sublime into a gaseous state due to the absorption of heat and produce a large amount of water mist. These water mists are exported to the outside of the shell through the mist outlet of the dry ice machine, creating a cloudy effect.

However, existing dry ice machines release a limited amount of water mist per unit time. For large stage applications, multiple dry ice machines and longer periods of time are required to generate sufficient water mist. But over time, the temperature of the water in the existing dry ice machine will gradually decrease, so that enough water mist can no longer be released. In addition, the mist from existing dry ice machines can cause large water spots on stage, increasing the risk of slip and injury for actors.

Furthermore, the existing dry ice machine requires an external power supply to supply the water pump. Electricity may also cause other safety issues. For example, the power cord used to connect the dry ice machine to the mains can cause the actor to trip over. In addition, if the water in the dry ice machine overflows, it may cause the danger of electric leakage or short circuit. In addition, if the operation is improper, the socket of the power supply line may fall off, causing the dry ice machine to stop working and affecting the performance.

Accordingly, how to improve the dry ice machine to overcome the above-mentioned defects is still one of the important issues to be solved by this business.

In addition, the term "or", as used herein, should include any one or a combination of more of the associated listed items, as the case may be.

[First Embodiment]

Referring to FIGS. 1 to 3 , an embodiment of the present invention provides a dry ice fog machine 1 , which can be used to generate fog to create a cloud effect during performances. The dry ice cloud fog machine 1 in this embodiment includes: a casing 10 , a lifting assembly 11 , a dry ice basket 12 and a fog outlet pipe 13 .

The housing 10 includes a main casing 100 and a top cover 102 . In this embodiment, the housing 10 further includes a partition structure 101 located near the bottom side, so as to partition the inner space of the main casing 100 into The liquid accommodating chamber R1 and the electric control chamber R2 are independent of each other. As shown in FIG. 1 , the liquid accommodating chamber R1 is located between the partition structure 101 and the top cover 102 , and the electric control chamber R2 is located between the partition structure 101 and the bottom plate of the main casing 100 .

The liquid accommodating chamber R1 of the main casing 100 can be used to hold liquid (eg, water). When the heated liquid contacts the dry ice, it will promote the sublimation of the dry ice and generate mist in the liquid accommodating chamber R1. The greater the amount of liquid that the main housing 100 can hold, the greater the heat stored by the liquid. When dry ice comes into contact with liquid, the longer it can continue to create clouds. In this embodiment, the main casing 100 is cylindrical, and can hold the largest amount of liquid in the smallest volume.

Please refer to Figure 1 first. In this embodiment, the wall of the main casing 100 has a hollow structure 100h, and the insulating medium is filled in the hollow structure 100h. The aforementioned heat insulating medium is, for example, air or foam. In detail, the main casing 100 of the housing 10 according to the embodiment of the present invention has a double-layered side wall. As shown in FIG. 1 , the main casing 100 has an inner sidewall 100b and an outer sidewall 100a opposite to the inner sidewall 100b, and the inner sidewall 100b and the outer sidewall 100a together define a hollow structure 100h.

When the dry ice is in contact with water (liquid), the cloud will absorb the heat in the water, causing the water temperature to drop. If the temperature of the water in the casing 10 cools down too quickly, or even drops to the freezing point, the dry ice will not be able to continuously generate fog, and a sufficient amount of fog will be produced. Therefore, before operating the dry ice fog machine 1, the liquid in the casing 10 should be heated to a specific temperature, such as 70oC to 80oC. In the embodiment of the present invention, the main casing 100 has a hollow structure 100h and is filled with a heat insulating medium, which can slow down the cooling rate of the liquid, keep the temperature at a higher temperature, and prevent the operator from being scalded.

Please refer to Figure 1, Figure 2 and Figure 4 again. FIG. 4 is a schematic cross-sectional view of the dry ice cloud fog machine of FIG. 3 . The dry ice cloud fog machine 1 of this embodiment further includes a heating assembly 14 , a temperature sensor 15 and a control module 16 .

In detail, please refer to FIG. 4 , the partition structure 101 of this embodiment has a stepped portion, and has a first stepped surface 101a, a second stepped surface 101b, and a spacer connected between the first stepped surface 101a and the second stepped surface 101b Connection surface 101c. In addition, the heating element 14 is assembled on the connecting surface 101c of the stepped portion, and extends along the second stepped surface 101b from the connecting surface 101c. That is to say, the heating tube of the heating assembly 14 will not protrude from the first step surface 101 a to avoid mutual interference with the dry ice basket 12 .

The temperature sensor 15 is disposed in the liquid accommodating chamber R1 to detect the temperature of the liquid. The control module 16 is disposed in the electric control room R2 and is electrically connected to the heating element 14 and the temperature sensor 15 . In one embodiment, the control module 16 can receive the signal detected by the temperature sensor 15 and control the power provided to the heating element 14 according to the signal of the temperature sensor 15 .

In this embodiment, the dry ice cloud fog machine 1 further includes an operation panel 17 which is electrically connected to the control module 16 . In addition, the operation panel 17 is provided outside the main casing 100 for the user to input instructions. The operation panel 17 includes a display for displaying the temperature detected by the temperature sensor 15 . The operation panel 17 may also include, but is not limited to, control keys, control buttons, a control panel or any combination thereof, to allow the user to turn on or turn off the heating assembly 14 through the operation panel 17 and input commands according to the temperature displayed on the display. The user can adjust the output power by controlling the number of the heating tubes to be turned on through the control module 16 . In one embodiment, the operation panel 17 may be a touch panel.

As shown in FIG. 1 and FIG. 3 , the top cover 102 is detachably assembled on the main casing 100 to close the liquid accommodating chamber R1 . In the present embodiment, a side edge of the top cover 102 has a gap 102h to avoid interfering with the movement of the lift assembly 11 . In addition, as shown in FIG. 1 , the top cover 102 further has at least one engaging structure 102e (two are shown as an example), so that the mist outlet pipe 13 can be assembled on the top cover 102 . The engaging structure 102e is, for example, a hole or a convex tube, which is not limited in the present invention.

Please continue to refer to FIG. 1 to FIG. 4 , the lift assembly 11 includes a lift member 110 and an operation member 111 . In this embodiment, the lifting member 110 is movably disposed on the casing 10 , and the operating member 111 is connected to the lifting member 110 to drive the lifting member 110 to move relative to the casing 10 along a lifting axis Z1 .

Please refer to FIG. 1 and FIG. 4 , the lifting member 110 of this embodiment has a U-shaped structure, And an opening of the U-shaped structure is disposed on the wall of the main casing 100 toward the main casing 100 . Further, the lifting member 110 includes an inner plate body 110b, an outer plate body 110a, and a bridging portion 110c connected between the inner plate body 110b and the outer plate body 110a. As shown in FIG. 4 , the bridging portion 110 c is arranged on the main casing 100 . In addition, the inner plate 110b extends downward from one end of the bridging portion 110c along the inner side wall 100b into the liquid accommodating chamber R1, and the outer plate 110a extends downward from the other end of the bridging portion 110c along the outer side wall 100a. extends and is located outside the main casing 100 .

In this embodiment, the lift assembly 11 further includes a guide member 112 to limit the movement path of the lift member 110 . As shown in FIGS. 3 and 4 , the guide member 112 of this embodiment is disposed on the outer side wall 100 a of the main casing 100 , and the lifting member 110 is movably disposed on the guide member 112 and the outer side wall of the main casing 100 . 100a. Specifically, the cross-sectional shape of the guide 112 is substantially C-shaped. That is to say, in this embodiment, the guide member 112 has a main plate portion (not numbered) and two side plate portions (not numbered) respectively connected to two opposite sides of the main plate portion. The two side plate portions are bent relative to the main plate portion. fold and extend toward the outer side wall 100 a of the main casing 100 . The outer plate body 110a of the lifting member 110 is disposed in the space defined by the main plate portion and the two side plate portions. Therefore, when the lift member 110 is driven to move relative to the guide member 112 , the two side plates of the guide member 112 can prevent the lift member 110 from deviating from the lift axis Z1 . Accordingly, the lifter 110 can move linearly along the lifter axis Z1 relative to the guide 112 .

In addition, the guide member 112 has a slot 112h. The slot 112h is located on the main board and extends along the lift axis Z1. The operating member 111 is combined with the lifting member 110 through the slot 112h. In this way, the user can hold the operating member 111 and move along the slot 112h, so as to drive the lifting member 110 to linearly move along the lifting axis Z1.

Please refer to FIG. 4 and FIG. 5A , wherein FIG. 5A shows a partial enlarged view of the operating element in the region V of FIG. 4 . As shown in FIG. 5A , in this embodiment, the operating member 111 includes a grip portion 111 a and a latch portion 111 b. The holding portion 111 a can be held by the user to control the movement of the lifting member 110 . The latch portion 111b is connected to the grip portion 111a, and the latch portion 111b passes through the slot 112h of the guide member 112 and is connected to the outer plate body 110a of the lifter 110 . Further, when the operating member 111 is in a fixed state, the latch portion 111b penetrates The outer plate body 110a of the lifting member 110 is set against the outer side wall 100a of the main casing 100, so that the lifting member 110 is fixed at a predetermined position. That is, when the latch portion 111b abuts against the outer side wall 100a of the main casing 100 , the lifting member 110 is also fixed and cannot move relative to the guide member 112 .

As shown in FIG. 5A , in one embodiment, the front end of the latch portion 111b has a screw structure 1110, and the outer plate body 110a has screw holes (not numbered). The threaded structure 1110 of the plug portion 111b is locked with the screw hole, so that the plug portion 111b is combined with the outer plate body 110a, but the invention is not limited to this. In other embodiments, the latch portion 111b may also engage with the outer plate body 110a.

Please refer to FIG. 5B , which shows a partial enlarged view of the operating member of FIG. 4 in a movable state. When the latch portion 111b is coupled to the outer plate body 110a but does not contact the outer side wall 100a of the main casing 100 , the lifting member 110 can be driven to move relative to the guide member 112 . Accordingly, when the user wants to adjust the position of the lifting member 110 , the user can rotate the holding portion 111 a until the latch portion 111 b is separated from the outer side wall 100 a of the main casing 100 . Afterwards, the user can drive the lift member 110 to move relative to the guide member 112 by moving the grip portion 111a.

Please refer to FIG. 2 and FIG. 4 again, the lift assembly 11 further includes a support portion 113 for carrying the dry ice basket 12 . The support portion 113 is located in the liquid accommodating chamber R1 and is connected to the inner plate body 110 b of the lifting member 110 . When the dry ice basket 12 is disposed in the liquid accommodating chamber R1 , the dry ice basket 12 may be disposed on the support portion 113 . The structure of the support portion 113 may be a cross shape, a rice shape or any other shape. As long as the structural strength of the support portion 113 is sufficient to support the weight of the dry ice basket 12 and the dry ice and does not prevent the liquid in the liquid accommodating chamber R1 from flowing into the dry ice basket 12 , the present invention does not limit the structural shape of the support portion 113 .

As shown in FIG. 1 to FIG. 3 , the dry ice basket 12 can be used for loading dry ice, and is detachably assembled on the lifting assembly 11 . The dry ice basket 12 has a plurality of perforations 12h, so that an inner space of the dry ice basket 12 is in fluid communication with the liquid accommodating chamber R1. When the dry ice basket 12 is assembled on the lifting assembly 11 , the user can drive the lifting member 110 to move along the lifting axis Z1 through the operating member 111 , thereby changing the height position of the dry ice basket 12 . The aforementioned height position refers to the height of the bottom end of the dry ice basket 12 relative to the second step surface 101b. when When the lifting member 110 rises or falls, the dry ice basket 12 is driven to rise and fall, so as to control the contact area between the dry ice and the liquid. The operation of the dry ice fog machine 1 will be described later.

When the capacity of the liquid accommodating chamber R1 is larger, it means that the storage volume is larger, the cooling speed of the liquid is slower, and the time for continuously releasing the mist is longer. Accordingly, the ratio between the capacity of the liquid accommodating chamber R1 and the capacity of the dry ice basket 12 can be designed according to actual needs, which is not limited in the present invention. In addition, the dry ice basket 12 of this embodiment also has a handle 121 , so that the user can set the dry ice basket 12 on the support portion 113 of the lift assembly 11 , or take out the dry ice basket 12 from the main casing 100 .

As shown in FIGS. 1 to 3 , the mist outlet pipe 13 is detachably assembled to the housing 10 to guide the mist generated in the liquid accommodating chamber R1 to the outside. In this embodiment, the mist outlet pipe 13 is detachably assembled on the top cover 102 .

Referring to FIG. 1 and FIG. 4 , the mist outlet pipe 13 includes a return section 131 and a bending section 132 . In this embodiment, the engaging structure 102e of the top cover 102 is a convex pipe, and one end of the return section 131 is sleeved on the convex pipe, so that the mist outlet pipe 13 is detachably assembled on the top cover 102 . The return section 131 extends upward (ie, a direction away from the bottom of the main casing 100 ), and the extension direction D1 of the return section 131 forms an acute angle with the lift axis Z1 . Preferably, the angle range of the acute angle formed by the extension direction D1 of the return section 131 and the lifting axis Z1 is between 0 and 45 degrees. Although the extending direction D1 shown in FIGS. 1 to 4 is substantially parallel to the lifting axis Z1 , the present invention is not limited thereto.

The bent section 132 is connected to the return section 131 and has a nozzle 132H. The bending section 132 is bent relative to the extending direction D1 of the recirculation section 131 to form a bending angle, and defines a fog exiting direction. In this embodiment, the cloud generated inside the main casing 100 is guided to the outside of the dry ice cloud machine 1 through the nozzle 132H of the bending section 132 . In this embodiment, the bending angle of the bending section 132 is greater than the acute angle formed between the extending direction D1 of the return section 131 and the lifting axis Z1 .

It should be noted that after the dry ice is in contact with the liquid, the dry ice absorbs heat and sublimates into a gaseous state to generate a large amount of mist. The mist usually carries a large number of water droplets (or condensation) together through the mist outlet pipe 13, and then flows out. Dry ice fog machine 1 outside. As the mist gradually fills the stage, water droplets (or condensation) in the mist can condense on the ground to form a water film, increasing the risk of slips for performers on stage. For the existing dry ice machine, the larger the amount of fog, the more water droplets in the fog, and the easier it is to form water spots on the stage, making the stage more slippery. However, if the amount of fog is reduced, it may not be possible to achieve the desired cloud and fog effect on the stage, especially the large stage.

Accordingly, in the present invention, the extension direction D1 of the return section 131 of the mist outlet pipe 13 is different from the mist outlet direction, and forms an acute angle with the lift axis Z1, which can reduce the humidity of the mist and overcome the above problems. In detail, when the mist generated in the main casing 100 passes through the return section 131 , the water droplets (or dew condensation) in the mist may condense on the inner wall surface of the return section 131 . Since the extending direction D1 of the recirculation section 131 is substantially parallel to a vertical direction, the water droplets (or dew condensation) condensed on the inner wall surface of the recirculation section 131 can be forced to return to the liquid accommodating chamber R1 .

In addition, since the extension direction D1 of the return section 131 of the mist outlet pipe 13 is different from the mist outlet direction, when the mist is sprayed from the mist outlet pipe 13, the water droplets condensed on the return section 131 are less likely to be brought to the stage together. In this way, the water droplets carried in the mist sprayed from the mist outlet pipe 13 can be reduced, and water films are less likely to be formed on the stage. That is to say, the dry ice cloud fog machine 1 of the embodiment of the present invention can generate a large amount of fog to achieve the expected cloud fog effect, and can avoid water stains remaining on the stage, which can reduce the performance of performers on the stage due to the slippery stage floor. risk of falling.

It should be noted that although the mist outlet pipe 13 in this embodiment is disposed on the top cover 102, the present invention is not limited to this. In other embodiments, the mist outlet pipe 13 can also be arranged on the main casing 100 instead. As long as the mist outlet pipe 13 has a return section 131 and a bending section 132, and the return section 131 extends upward, and the acute angle formed between the extending direction D1 and the lifting axis Z1 does not exceed 90 degrees (preferably, does not exceed 45 degrees), It also reduces the humidity of mist.

In the present invention, the flow rate and humidity of the mist can be controlled by adjusting the length of the return section 131 and the aperture of the nozzle 132H. For example, if the aperture of the nozzle 132H is larger, the mist The larger the flow rate, the higher the humidity of the mist. However, if the length of the return section 131 is increased, the humidity of the mist can be reduced. Therefore, the hole diameter of the spout 132H and the length of the return section 131 can be adjusted according to actual needs.

Please refer to FIG. 6 and FIG. 7 , which respectively show schematic diagrams of the use states of the lifting member of the dry ice cloud fog machine in different predetermined positions according to the embodiment of the present invention. As shown in FIG. 6 , the user can control the operating member 111 to pull the lifting member 110 along the lifting axis Z1 to a first predetermined position to be fixed. The liquid L is loaded in the liquid accommodating chamber R1, and the liquid L is heated by the heating component 14 to a predetermined temperature, for example: 70oC to 80oC. In addition, the dry ice basket 12 loaded with the dry ice S is set on the support portion 113 of the lift assembly 11 . At this time, the position of the dry ice basket 12 is higher than the surface of the liquid L without contacting the liquid L. The top cover 102 is disposed on the casing 10 and closes the liquid accommodating chamber R1.

When the cloud needs to be generated, the user releases the latch portion 111b of the operating member 111 (as shown in FIG. 5B ), so that the lifting member 110 can move downward relative to the housing 10 . As shown in FIG. 7 , after the user drives the lifting member 110 to descend through the operating member 111 , the heated liquid L can contact the dry ice S through the perforations 12h of the dry ice basket 12 to generate clouds.
