Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a helmet cleaning cabinet with a fixed structure. Background Art

[0002] As a kind of safety protection equipment, hard hats are widely used in places such as the vicinity of dormitory buildings of construction projects, outside engineering command centers, workshop entrances of various enterprises, ships or offshore platforms, etc., to improve the construction safety of the wearers.

[0003] At present, safety helmets need to be worn every day in various places where they are required, especially in construction sites and other places. The inside and outside of the safety helmets are commonly contaminated to varying degrees. In severe cases, bacteria and viruses are easily bred inside the safety helmets, and may even cause certain head skin diseases.

[0004] For this reason, and because the infrastructure at construction sites is mostly not perfect, some places now often collect safety helmets for centralized cleaning, and distribute them after cleaning. Although this method can achieve the maintenance of safety helmets, it takes a lot of time and manpower to receive and send safety helmets and centralized cleaning, which will extend the cost and time of construction.

[0005] In order to solve the above problems, the existing cleaning cabinet for safety helmets is equipped with a water spray head, which can clean the safety helmet. However, when the water pressure of the water spray head is low, it is difficult to clean the safety helmet. When the water pressure of the water spray head is high, the safety helmet is easy to collide with the inner wall of the cleaning pipe under the impact of the water flow. Therefore, it is easy for the safety helmet to damage the equipment in the cleaning cabinet or the equipment in the cleaning cabinet to damage the safety helmet. Utility Model Content
