Description

Technical Field

[0001] This utility model relates to the field of spray technology, and in particular to a dry ice spray device. Background Technology

[0002] A stage is the space provided in a theater for actors to perform, allowing the audience to focus their attention on the actors and achieve an ideal viewing experience. A stage typically consists of one or more platforms, some of which can be raised and lowered. Types of stages include proscenium stages, extended stages, circular stages, and rotating stages. With technological advancements, the viewing experience can be greatly enhanced through atmospheric effects such as lighting, pyrotechnics, and smoke.

[0003] Existing spraying methods generally fall into two categories: one involves condensing water vapor in the air into a mist, while the other uses mechanical energy to directly atomize water. Direct atomization requires high pressure and specialized nozzles to achieve large-scale water atomization, making it relatively expensive. Furthermore, ultrasonic atomization produces insufficient mist, making it unsuitable for stage applications. The most common condensation method uses dry ice for atomization. However, dry ice has a boiling point of -78.5℃, and even without misting, it sublimates continuously, resulting in waste. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a dry ice atomizing device, comprising an insulated outer shell, a nozzle structure at the upper end of the insulated outer shell, and a dry ice bucket fixedly connected inside the insulated outer shell. The dry ice bucket includes a bucket body, with an inner and outer conductive mesh fixedly connected to the lower side wall of the bucket body. An inner insulating sleeve is fitted onto the outer side of the dry ice bucket, and a fan is fixedly connected to the lower end of the insulated outer shell. In use, dry ice is placed in the dry ice bucket, and then the fan operates. Outside air enters the interior of the insulated outer shell, flows into the inner insulating sleeve from the upper end, passes through the mesh, enters the interior of the dry ice bucket, and is then expelled upwards from the nozzle structure. The air entering the dry ice bucket is cooled, and upon exiting, the water vapor in the air is condensed, thus achieving an atomization effect. The use of an insulated outer shell and an inner insulating sleeve reduces the loss of cold energy, improves the utilization rate of dry ice, and the design of two-fold airflow ensures that the escaping cold energy pre-cools the incoming air.

[0005] Preferably, the upper end of the heat-insulating shell is provided with a through hole, and the nozzle structure includes a cover plate. An air outlet pipe is fixedly connected to the middle of the upper end of the cover plate, and the air outlet pipe is connected to the through hole. That is, the cooled air passes through the through hole and is finally sent out from the air outlet pipe. If necessary, a pipe can be connected to the air outlet pipe to realize long-distance transportation of cooling air.

[0006] Preferably, the lower sidewall of the through hole is fixedly connected to an inner edge, and the upper end of the bucket body is provided with an annular upper edge. A countersunk hole is provided on the inner edge, and a bolt is provided in the countersunk hole. The bolt passes downward and is threadedly connected to the upper edge. That is, the dry ice bucket is fixedly connected to the bottom of the through hole by bolts.

[0007] Preferably, a slot is provided in the middle of the through hole, and several openings are provided in the upper part of the through hole, extending to the slot. A locking block is provided on the lower side wall of the cover plate. When dry ice needs to be replenished, the nozzle structure can be rotated so that the locking block and the openings coincide, and then lifted upwards to expose the through hole, allowing dry ice to be added to the dry ice bucket. Installing the nozzle structure is the reverse process of opening.

[0008] Preferably, a handle is fixedly connected to the upper end of the cover plate. The handle provides an area for holding and rotating the nozzle structure.

[0009] Preferably, a support rod is fixedly connected to the lower part of the inner insulation sleeve, and several connecting protrusions are fixedly connected to the inner wall of the insulation shell. A bolt is inserted through the end of the support rod, and the bolt and the connecting protrusion are threaded together. That is, the inner insulation sleeve and the dry ice bucket do not contact each other, and the support rod and the inner insulation sleeve are fixed together by bolts.

[0010] Preferably, a number of support feet are fixedly connected to the lower edge of the insulation shell. The support feet lift the insulation shell off the ground, ensuring that the fan can draw in sufficient air.

[0011] The beneficial effects of this utility model are as follows: it is equipped with an insulated outer shell and an inner insulated sleeve, and it allows the air to turn twice, that is, it is equipped with two air layers on the outside of the dry ice bucket, which maximizes the utilization rate of dry ice.

[0022] like Figures 1 to 6 As shown, a dry ice spraying device includes an insulated outer shell 2, which is thickened and insulated with a thermal insulation material. The insulated outer shell 2 is cylindrical in shape and has a conical surface at its upper edge. A nozzle structure 3 is provided at the upper end of the insulated outer shell 2 to deliver cooled air. A dry ice bucket 8 is fixedly connected inside the insulated outer shell 2. The dry ice bucket 8 stores dry ice for cooling the air and also sublimates into low-temperature gas. The dry ice bucket 8 includes a bucket body 82. A mesh 81 with internal and external communication is fixedly connected to the lower side wall of the bucket body 82. Air enters the interior of the bucket body 82 through the mesh 81. Dry ice can be fully cooled, and its sublimation is faster. An inner insulation sleeve 7 is fitted around the outside of the dry ice bucket 8. The design of the inner insulation sleeve 7 requires air to bend twice before entering the dry ice bucket 8, that is, there are two air layers on the outside of the dry ice bucket 8. This air can absorb the dissipated cold energy and improve the utilization rate of dry ice. The design of the insulation shell 2 and the inner insulation sleeve 7 further prevents the dissipation of cold energy when the device is not in use. The lower end of the insulation shell 2 is penetrated and fixedly connected to a fan 4. When the fan 4 is working, it draws the air from the lower part into the interior of the insulation shell 2.

[0023] The upper end of the heat-insulating shell 2 is provided with a through hole 21. The nozzle structure 3 includes a cover plate 33. An air outlet pipe 34 is fixedly connected to the middle of the upper end of the cover plate 33, and the air outlet pipe 34 is connected to the through hole 21. That is, the colder gas is sent out from the through hole 21 and finally sent out from the air outlet pipe 34 to atomize the water vapor in the air. If necessary, a pipeline can be connected to the air outlet pipe 34 to change the position of the atomization area.

[0024] An inner edge 22 is fixedly connected to the lower side wall of the through hole 21. The inner edge 22 is a circular convex ring. An annular upper edge 83 is provided at the upper end of the bucket body 82. A countersunk hole is provided on the inner edge 22. A bolt is provided in the countersunk hole. The bolt passes downward and is threaded to the upper edge 83. That is, the upper end face of the upper edge 83 is attached to the lower end face of the inner edge 22, and the two are fixedly connected by the bolt. That is, the dry ice bucket 8 is located directly below the through hole 21.

[0025] A slot 23 is provided in the middle of the through hole 21, and several openings 24 are provided in the upper part of the through hole 21, extending to the slot 23. A locking block 32 is provided on the lower side wall of the cover plate 33. When removing the nozzle structure 3, by rotating the cover plate 33, the locking block 32 and the opening 24 are aligned, and the nozzle structure 3 can be lifted upwards. At this time, dry ice can be added to the exposed dry ice bucket 8. Installing the nozzle structure 3 is the reverse process of removing it.

[0026] A handle 31 is fixedly connected to the upper end of the cover plate 33. The handle 31 is provided for easy gripping and rotation of the cover plate 33.

[0027] The lower part of the inner insulation sleeve 7 is fixedly connected to a support rod 5. Similarly, the support rod 5 is fixed to the inner insulation sleeve 7 by bolts. Several connecting protrusions 6 are fixedly connected to the inner wall of the insulation shell 2. Bolts are inserted at the end of the support rod 5 and the bolts are threadedly connected to the connecting protrusions 6. The inner insulation sleeve 7 is fixedly connected to the bottom of the dry ice bucket 8 by means of the connecting protrusions 6 and the support rod 5.

[0028] Several support feet 1 are fixedly connected to the lower edge of the insulation shell 2. The support feet 1 are used to lift the insulation shell 2 off the ground, which facilitates the fan 4 to draw in air.
