Description

Technical Field

[0001] The utility model relates to the technical field of small-aperture dry ice cleaning machines, in particular to a small-aperture dry ice cleaning machine. Background Art

[0002] Dry ice cleaning machine is a kind of cleaning machine. Dry ice cleaning has been rapidly developed around the world. The cleaning system uses high-pressure air to spray dry ice particles from the dry ice cleaning machine onto the working surface that needs to be cleaned. The physical reaction of temperature difference is used to make different substances separate at different shrinkage speeds. When the dry ice particles at -78 degrees Celsius come into contact with the dirt surface, a brittle explosion phenomenon will occur, causing the dirt to shrink and loosen. Then the dry ice particles will instantly vaporize and expand 800 times, generating a strong peeling force, quickly and thoroughly removing the dirt from the surface of the object, thereby achieving a fast, efficient, safe and energy-saving cleaning effect. The carbon dioxide used in dry ice cleaning comes from industrial waste gas, high-altitude air separation, etc. Dry ice cleaning itself does not produce carbon dioxide.

[0003] Existing dry ice cleaning machines spray dry ice onto the surface of parts. For through holes inside some parts, such as threaded holes used to fix parts, these through holes are generally small in size, and existing dry ice cleaning machines have no way to clean them in a targeted manner. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art and provide a small-aperture dry ice cleaning machine.

[0005] The purpose of the utility model is achieved through the following technical solutions: a small-aperture dry ice cleaning machine, comprising a fixed frame; a dry ice device, the dry ice device is arranged on the fixed frame; a connecting pipe, one end of the connecting pipe is connected to the dry ice device; a handheld cleaning gun, the handheld cleaning gun is connected to the other end of the connecting pipe, the handheld cleaning gun comprises a handheld cleaning gun body and a gun head, and the diameter range of the gun head is 1mm-3mm.

[0006] Furthermore, the gun head includes an outlet portion, a connecting portion and a fixing portion.

[0007] Furthermore, the fixing portion is threadedly connected to the handheld cleaning gun body.

[0008] Furthermore, the outlet portion includes an outlet surface and a transition surface, the transition surface is a cambered surface, and the outlet surface is an inclined surface.

[0009] Furthermore, the curvature range of the transition surface is 30 0 -45 0 .

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model can clean through holes with smaller apertures by providing a handheld cleaning gun with a small aperture, and at the same time, an outlet surface and a transition surface are provided at the gun head, and dry ice can be hit on the hole wall of the through hole by utilizing the curvature thereof, so that cleaning is more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the structure of the utility model;

[0013] Figure 2 It is a structural schematic diagram of the gun head of the utility model;

[0014] Figure 3 It is a structural schematic diagram of the outlet surface and transition surface of the utility model. DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1-3 As shown, a small-aperture dry ice cleaning machine includes: a fixed frame 100; a dry ice device 200, wherein the dry ice device 200 is arranged on the fixed frame 100; a connecting pipe 300, wherein one end of the connecting pipe 300 is connected to the dry ice device 200; a handheld cleaning gun 400, wherein the handheld cleaning gun 400 is connected to the other end of the connecting pipe 300, and the handheld cleaning gun 400 includes a handheld cleaning gun body 410 and a gun head 420, wherein the diameter of the gun head 420 ranges from 1 mm to 3 mm.

[0017] The gun head 420 includes an outlet portion 421, a connecting portion 422 and a fixing portion 423. The fixing portion 423 is threadedly connected to the handheld cleaning gun body 410. The outlet portion 421 includes an outlet surface 4211 and a transition surface 4212. The transition surface 4212 is a curved surface, and the outlet surface 4211 is an inclined surface. The curvature range of the transition surface 4212 is 30 0 -45 0 .

[0018] It should be noted that when the utility model is in use, the dry ice device 200 is opened, and then the handheld cleaning gun 400 is aimed at the through hole, and the handheld cleaning gun 400 is opened, and dry ice is sprayed from the gun head 420 and sprayed into the through hole. Since the transition surface 4212 is an arc surface and the outlet surface 4211 is an inclined surface, the dry ice can be directly sprayed onto the inner wall of the through hole, so as to thoroughly and efficiently clean the through hole.

[0019] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
