Spraying device for PTC heating material for toilet ring and spraying method

Abstract

The invention discloses a spraying device for a PTC heating material for a toilet ring. The spraying device comprises a material supply part, a material blowing and conveying part, spraying and guiding parts and a heating element, wherein the material supply part is used for storing and guiding out the PTC heating material. The material blowing and conveying part is used for blowing and conveyingthe PTC heating material to the toilet ring to form a PTC heating layer. The spraying and guiding parts are arranged on the side of an outlet of the material blowing and conveying part and is used forguiding the PTC heating material blown out from the material blowing and conveying part so as to prevent the PTC heating material from being sprayed out of the preset range and used for drying the PTC heating layer. The spraying and guiding parts guide the PTC heating material through cold air. The spraying and guiding parts dry the PTC heating layer through hot air. The heating element is used for heating the cold air into hot air. In the spraying process, the PTC heating material can be effectively prevented from being sprayed out of the preset range, the PTC heating material can also be dried in the spraying process, the spraying efficiency is improved, and incomplete drying of the PTC heating material layer is avoided.

Description

technical field [0001] The invention relates to the technical field of material spraying, in particular to a spraying device and a spraying method of a PTC heating material for a toilet seat. Background technique [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 underside 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.

[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
