Description

一种防水电暧器 本实用新型涉及一种电暧器，尤其是一种可以设置在室外的防水电暧 器。  The utility model relates to an electric smashing device, in particular to a waterproof electric shovel which can be arranged outdoors.
背景技术 Background technique
目前市场上适合于室外使用的电暖器品种不多，由于这种电暖器是室 外使用， 因此必须解决雨天防水的问题。市场上现有的此类防水电暧器通 常是采用整体密封的方式来达到防水的效果，即在金属壳体的敞口端整体 设置玻璃密封罩，这类电暖器由于发热体设置在封闭的壳体内，长时间使 ^壳体内温度持续升高，对玻璃材料的耐热性能要求很高， 旦.这种玻璃罩 在实现密封防水的同时也会挡住发热体的热量向外散发，不但影响取暧效 果， 还会因发热体的工作环境温度过高而影响发热体使用寿命， 同时， 玻 璃罩内温度过高过热还可能出现玻璃炸裂的状况，存在安全隐患。随着人 们生活方式的逐渐变化，室外电暖器越来越普及，这类产品的缺陷也变得 日益突出， 有待进一步改良。  At present, there are not many types of electric heaters suitable for outdoor use on the market. Since such electric heaters are used outdoors, it is necessary to solve the problem of waterproofing in rainy days. The existing waterproof electric picks on the market usually adopt the method of integral sealing to achieve the waterproof effect, that is, a glass sealing cover is integrally disposed at the open end of the metal casing, and the electric heater is arranged in the closed state due to the heating body. In the casing, the temperature inside the casing is continuously increased for a long time, and the heat resistance of the glass material is required to be high. Once the glass cover is sealed and waterproof, the heat of the heating body is blocked from being emitted. Affecting the effect of picking up, it will also affect the service life of the heating element due to the high temperature of the working environment of the heating element. At the same time, if the temperature inside the glass cover is too high, the glass may burst and there is a safety hazard. With the gradual changes in people's lifestyles, outdoor heaters are becoming more and more popular, and the defects of such products have become increasingly prominent and need further improvement.
