[0030] See also Figure 1-8 The utility model provides a technical solution, a defrosting device for a cold storage, wherein a cylindrical cavity is arranged at the axis of a hollow rod body 1.

[0031] The connecting block 2 is fixed to the bottom end of the hollow rod body 1 by welding or other methods, and an inner cavity 2.2 communicating with the inner cavity of the hollow rod body 1 is provided in the connecting block 2, and rotating shafts 2.1 are respectively provided in the middle of the two side walls of the connecting block 2.

[0032] The middle part of the top surface of the shovel plate 3 is fixed to the bottom surface of the connecting block 2 by welding or the like, a horizontal column cavity 3.1 is provided near the top end of the shovel plate 3, a vertical hole 3.2 is provided on the top of the shovel plate 3, the top end of which is connected to the bottom end of the inner cavity 2.2 and the bottom end is connected to the middle part of the horizontal column cavity 3.1, and a plurality of inclined holes 3.3 are provided in the horizontal direction near the bottom end of the front wall of the shovel plate 3, the top end of which is connected to the horizontal column cavity 3.1.

[0033] The bottom end of the cylindrical shell 5 is fixedly connected to the top end of the hollow rod body 1 by welding or other methods, and a notch 5.1 is provided at the top end of the side wall of the cylindrical shell 5.

[0034] The hot air gun 7 is fixedly sleeved in the cylindrical shell 5, and the air outlet of the hot air gun 7 is sleeved on the top of the inner cavity of the hollow rod body 1. The hot air gun 7 is a mini hot air gun with an operating temperature of 250-350°C, a rated power of 300W, and a voltage / frequency of 220V / 50Hz. The switch button of the hot air gun 7 is stuck in the slot 1 5.1.

[0035] The sweeping mechanism 4 comprises a plate body 4.1 abutting against the top of the front wall of the shovel plate 3, ear plates 4.3 whose bottom ends are fixed to both sides of the middle of the top surface of the plate body 4.1 and whose top ends are rotatably mounted on the rotating shaft 2.1, and a plurality of bristles 4.2 whose top ends are sleeved on the bottom surface of the plate body 4.1. An ear seat 4.4 is fixed in the middle of the front wall of the plate body 4.1.

[0036] The bottom end of the pull rod 8 is hinged in the ear seat 4.4, the top of the pull rod 8 is hinged with a hinge block 8.2, the rear wall of the hinge block 8.2 is fixed with a screw 8.3, and the top of the front wall of the hollow rod body 1 and the position near the top are respectively fixed with a threaded sleeve 1.1 that matches the threaded sleeve of the screw 8.3.

[0037] The handle 6 includes a sleeve 6.2 that is matched with the top of the cylindrical shell 5 and a hand-held ring 6.1 fixed to the top surface of the sleeve 6.2. A slot 2 6.2.1 is provided at the bottom of the side wall of the sleeve 6.2 corresponding to the position of the button switch of the hot air gun 7. After the sleeve 6.2 is sleeved on the top of the cylindrical shell 5, it is fixed with radial screws to improve the connection strength between the sleeve 6.2 and the cylindrical shell 5. The slot 1 5.1 and the slot 2 6.2.1 are opposite to each other, so that the button switch of the hot air gun 7 is exposed from the slot 1 5.1 and the slot 2 6.2.1, so as to facilitate the operation of turning the hot air gun 7 on and off.

[0038] In summary, when defrosting is performed in a cold storage, the screw 8.3 on the hinge block 8.2 is first threadedly sleeved into the threaded sleeve 1.1 at the top of the front wall of the hollow rod body 1. At this time, the pull rod 8 pulls up the cleaning mechanism 4 through the ear seat 4.4, so that the cleaning mechanism 4 turns upward with the rotating shaft 2.1 as the axis.

[0039] At this time, the hot air gun 7 is turned on by the button switch, and the high-temperature airflow generated by the hot air gun 7 flows through the inner cavity of the hollow rod body 1, the inner cavity 2.2 of the connecting block 2, the vertical hole 3.2, and the horizontal column cavity 3.1 in sequence, and is ejected from the bottom end of the inclined hole 3.3. Combined with the scraping effect of the bottom edge of the scraper plate 3, the frost removal effect is greatly improved.

[0040] The screw rod 8.3 on the hinge block 8.2 is moved and sleeved into the threaded sleeve 1.1 below. At this time, the pull rod 8 pushes the cleaning mechanism 4 downward, so that the plate body 4.1 is close to the front wall of the shovel plate 3, and the bottom end of the bristle 4.2 is lower than the bottom end of the shovel plate 3, so as to facilitate the cleaning of the accumulated frost after shoveling, and further improve the defrosting effect.

[0041] In addition, in order to further improve the convenience of operation, the hollow cylinder 1, the connecting block 2, the shovel plate 3, the cylindrical shell 5, and the handle 6 are made of lightweight materials such as aluminum alloy and high-strength plastic.
