Description

Technical Field

[0001] This utility model relates to a cleaning device, and more particularly to a cleaning device utilizing dry ice. Background Technology

[0002] Dry ice cleaning machines are a type of cleaning machine, and dry ice cleaning has seen rapid development globally. The cleaning system uses high-pressure air to propel dry ice particles onto the work surface to be cleaned. The physical reaction caused by the temperature difference causes different substances to detach at different contraction rates. When the -78°C dry ice particles come into contact with the dirt surface, they undergo embrittlement and explosion, causing the dirt to shrink and loosen. The dry ice particles then instantly vaporize and expand 800 times, generating a powerful peeling force that quickly and thoroughly removes the dirt from the object's surface, achieving a fast, efficient, safe, and energy-saving cleaning effect. The carbon dioxide used in dry ice cleaning comes from industrial waste gas and high-altitude air separation. Dry ice cleaning itself does not produce carbon dioxide.

[0003] Traditional dry ice cleaning machines are generally used in commercial and industrial settings, thus requiring the use of large screw air compressors, resulting in a bulky and inconvenient machine. Even some smaller, household-use dry ice cleaning machines still present numerous problems, such as difficulty in moving them during use. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] refer to Figures 1-5 This embodiment provides a shoulder strap dry ice cleaning machine, including: a dry ice cleaning machine body 1, a spray gun, and a shoulder strap 2; the shoulder strap 2 is connected to the back of the dry ice cleaning machine body 1. By providing the shoulder strap 2, users can carry the dry ice cleaning machine body 1 for use. Of course, to enable users to carry the dry ice cleaning machine body 1, its weight needs to be reduced. This application mainly reduces the weight of the rotary cutting disc and the transmission mechanism. In addition to the double shoulder strap shown in this embodiment, the shoulder strap 2 can also be replaced with a single shoulder strap or other common shoulder straps.

[0027] Furthermore, due to the miniaturized and lightweight design of the dry ice cleaner, the corresponding air pipe diameters have been reduced, allowing for the miniaturization of the compatible air compressor. Therefore, this embodiment also includes a portable air compressor, whose outlet is connected to the inlet of the dry ice cleaner body 1, and the outlet of the dry ice cleaner body 1 is connected to the spray gun.

[0028] In order to reduce the weight of the transmission mechanism and the rotary cutting disc, the dry ice cleaning machine body 1 in this embodiment includes a lightweight rotary cutting device for block dry ice.

[0029] The lightweight rotary cutting device further includes a transmission device 11, a rotary cutting plate 12, and a container 13; the transmission device 11 is used to drive the rotary cutting plate 12 to rotate.

[0030] The container 13 is used to hold dry ice, and a pressing device 14 is provided on the first side of the container 13. The pressing device 14 is used to push the dry ice to the second side, and the rotary cutting plate 12 is provided on the second side. A blade is fixed on the rotary cutting plate 12. The blade is inclined from the second side to the first side, and a gap is left between the blade and the rotary cutting plate 12. In this embodiment, the pressing device 14 is a push plate driven by a cylinder.

[0031] The side of the rotary cutting plate 12 away from the container 13 is connected to the fixed plate 16 via a connecting post 15; the fixed plate 16 has a mounting hole at its axis for fixing the rotary cutting plate shaft 17; the fixed plate 16 has a through groove along its thickness direction for weight reduction.

[0032] The transmission device 11 is mainly used to drive the rotary cutting plate 12 to rotate. During the rotation, the rotary cutting plate 12 comes into contact with the dry ice block in the container 13, and the blades on the rotary cutting plate 12 can cut the dry ice block into pieces. The cut dry ice block is blown out by the air compressor to form an airflow containing dry ice particles, which is sprayed out from the spray gun to achieve the purpose of cleaning. The transmission device 11 includes: a brushless motor 111 and a gear transmission mechanism 112; the gear transmission mechanism 112 includes a first gear set on the output shaft of the brushless motor 111, a second gear set on the rotary cutting plate rotating shaft 17 of the rotary cutting device, and an intermediate gear connected between the first gear and the second gear. As a simple alternative to this embodiment, the intermediate gear can also be removed, and the first gear and the second gear can be directly meshed.

[0033] By replacing the metal chain drive with a gear drive, the weight of the transmission mechanism can be significantly reduced. Furthermore, the materials of the first gear, second gear, and intermediate gear can be changed from metal to nylon, achieving even greater weight reduction.

[0034] Furthermore, since the second gear on the rotary cutting plate 12 is relatively large, a through groove can be provided on the second gear along the thickness direction to further reduce weight.

[0035] To fix the second gear and the rotary cutting plate shaft 17, the rotary cutting plate shaft 17 is mounted on the side of the second gear facing the rotary cutting plate 12 via a fixing pin. Further, the rotary cutting plate shaft 17 includes a shaft body 171 and a mounting plate 172. The mounting plate 172 is provided with an insertion hole for connection with the fixing pin; the mounting plate has a through groove along its circumferential direction for weight reduction.

[0036] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
