Description

Wet piece of cloth heating box

Technical Field

The invention relates to a paper towel dispensing device, in particular to a wet towel heating box.

Background

Wet wipes are moist paper towels used to wipe skin. Wet wipes can be broadly divided into two categories: one is that it is already sterilized by itself, but it cannot sterilize other objects, and it can only be used to wipe and moisturize the skin; the other type of the disinfectant can not only disinfect the disinfectant, but also disinfect other articles, and can be used for disinfecting or sterilizing skin scratches, scratches and the like. In some care scenarios for hospital patients, such as perianal cleaning after defecation of a bedridden patient, it is necessary to clean a specific part of the patient's body with a wet wipe. However, in the case of low temperature in winter, the wet tissue is directly used for wiping, which can cause irritation to the skin and lead the patient to experience poor.

In order to heat the wet towel, patent document CN203953499U discloses a wet towel heater in the prior art. The heater comprises a box body and a box cover covering the box body; the box cover comprises an upper cover body and a lower cover body, the lower cover body is provided with a drawing opening, the upper cover body covers the drawing opening, so that a heating cavity is formed at the periphery of the drawing opening, and a PET metal heating film is arranged in the heating cavity; the metal heating film plays a role in warming the wet tissue by heating the periphery of the extraction opening of the wet tissue. However, the conventional wet tissues are generally contained in the box body in a whole bag, and there are the following two cases when the wet tissues are used. Firstly, in order to avoid the wet tissues from being heated and dried, the opening of the wet tissue bag is opened only when the wet tissues are extracted, the wet tissues can be heated only when being extracted, and the temperature of the wet tissues is difficult to increase. Secondly, the opening of the wet tissue bag is always kept open, part of the wet tissue to be drawn out can extend into the heating cavity from the box bottom, but the uniform heating of the wet tissue cannot be ensured during heating, and the heating effect of the wet tissue is influenced; moreover, because the wet tissue bag is always open, even if the upper cover body is sealed, the wet tissue liquid contained in the wet tissue bag is easy to volatilize, and the using effect of the wet tissue is affected.
