A spraying device and spraying method of PTC heating material for toilet seat

Abstract

The invention discloses a spraying device of PTC heating material for toilet seat, which comprises: a material supply part for storing and exporting PTC heating material; a material blowing part for blowing PTC heating material onto the toilet seat to form a PTC heating layer; spraying guide part, which is arranged on the side of the outlet of the material blowing part, for guiding the PTC heating material blown out from the material blowing part, to avoid the PTC heating material being sprayed outside the preset range , and used to dry the PTC heating layer; and a heating element; wherein, the spraying guide guides the PTC heating material through cold air, and the spraying guide dries the PTC heating layer through hot air; the heating element is used for The cold air is heated into the hot air. In the spraying process, not only can effectively avoid the PTC heating material spraying out of bounds, but also can dry the PTC heating material in the spraying process, improve the spraying efficiency, and avoid the incomplete drying of the PTC heating material layer.

Description

Technical field [0001] The present invention relates to the field of material spraying techniques, and more particularly to a spraying apparatus and a spraying method for a PTC heating material for a toilet ring. Background technique [0002] The setting of the PTC heating element can be constantly heated to the toilet loop, but it can cause unevenness of the toilet ring heating temperature, in order to avoid temperature uneven, people start attempting to coat the PTC polymer material to the lower side of the toilet loop as the heating layer. [0003] Usually, the PTC polymer material is used as the heating layer to spray the PTC polymer material to the lower portion of the toilet ring, and the conventional spraying device is low, it is difficult to meet the needs of high-efficiency production; at the same time, the PTC polymer material is easily used during the spraying process. Spray out, resulting in a position that should not be sprayed by the PTC polymer material, the PTC po...

Problems solved by technology

[0002] The setting of the PTC heating element can heat the toilet seat at a constant temperature, but it will lead to uneven heating temperature of the toilet seat. In order to avoid uneven temperature, people began to try to coat the PTC polymer material on the lower side of the toilet seat as a heating layer.

[0003] Usually the PTC polymer material is used as the heating layer to spray the PTC polymer material on the lower part of the toilet seat. The spraying efficiency of the conventional spraying device is low, and it is difficult to meet the needs of high-efficiency production; at the same time, the PTC polymer material is easily damaged during the spraying process. Spraying is out of bounds, resulting in the position that should not be sprayed is also covered by the PTC polymer material. Not only is it time-consuming and laborious to remove the PTC polymer material that is sprayed out of the bounds, but once the removal is not complete, leakage will occur due to the conductivity of the PTC polymer material Problems that affect the safety of the toilet seat
