一种含有等温除湿功能的护目镜A kind of goggles with isothermal dehumidification function

技术领域technical field

本发明涉及一种冷热联动等温除湿的空气处理装置，属于暖通空调领域，具体是一种采用半导体热电芯片实现等温除湿功能的医用护目镜。The invention relates to an air treatment device for isothermal dehumidification with linkage between cooling and heating, belonging to the field of heating, ventilation and air conditioning, in particular to medical goggles that use a semiconductor thermoelectric chip to realize the isothermal dehumidification function.

背景技术Background technique

随着新型冠状病毒等流行性病毒的袭来及迅速蔓延，医用护目镜已成为医护人员不可或缺的医疗装备。由于新型冠状病毒的传染性，医用护目镜不仅要防止近距离接触患者时，患者的血液，体液及分泌液飞溅到医护人员的眼睛部位，而且要避免空气传播引起医护人员的眼部感染的可能。为了避免空气传播引起的眼部感染，就必须对护目镜内部进行密闭处理，防止护目镜与外部空气进行换气。在护目镜内部换气效率为零的条件下，面部汗液和眼睛呼吸将导致护目镜内空气湿度过大，引起镜片结露；而且空气流通率较低，引起医护人员面部不适等情况。With the advent and rapid spread of epidemic viruses such as the new coronavirus, medical goggles have become an indispensable medical equipment for medical staff. Due to the infectivity of the new coronavirus, medical goggles should not only prevent the patient's blood, body fluids and secretions from splashing to the eyes of the medical staff when they are in close contact with the patient, but also avoid the possibility of airborne infection of the medical staff's eyes. . In order to avoid eye infections caused by airborne, it is necessary to seal the inside of the goggles to prevent the goggles from being ventilated with the outside air. Under the condition that the ventilation efficiency inside the goggles is zero, facial sweat and eye breathing will cause the air humidity in the goggles to be too high, causing condensation on the lenses; and the air circulation rate is low, causing facial discomfort for medical staff.

现有的自动清洁护目镜主要是通过传动机构自动清除外部扬尘引起的镜面污渍，但是，这种自清洁护目镜也有明显的局限性。例如，该护目镜无法解决内部空气湿度过大引起的镜片结露问题，特别是寒冷的冬季，室外温度较低，导致镜片温度低于露点温度，进而引起镜片内表面严重的结露现象，使得医护人员视线模糊，其次，这种自动清洁护目镜在祛除污渍方面具有滞后性，更不能促使护目镜内部空气的流动。经过检索，中国专利公布号为CN 110632774 A，发明名称为：一种自动清洁镜片的护目镜，该自动清洁功能主要由清洁机构和自控机构组成，其目的是清除恶劣天气下镜片外表面的污渍。The existing self-cleaning goggles mainly use the transmission mechanism to automatically remove the mirror surface stains caused by external dust. However, such self-cleaning goggles also have obvious limitations. For example, the goggles cannot solve the problem of condensation on the lens caused by excessive internal air humidity, especially in cold winter, when the outdoor temperature is low, the temperature of the lens is lower than the dew point temperature, which in turn causes serious condensation on the inner surface of the lens, making the The vision of medical staff is blurred, and secondly, the self-cleaning goggles have a lag in removing stains, and cannot promote the flow of air inside the goggles. After searching, the Chinese patent publication number is CN 110632774 A, and the name of the invention is: an automatic cleaning lens goggles, the automatic cleaning function is mainly composed of a cleaning mechanism and an automatic control mechanism, and its purpose is to remove the stains on the outer surface of the lens in bad weather .

半导体热电芯片可以同时实现制冷制热，当半导体热电芯片冷端温度低于空气露点时，可以对护目镜内部的空气进行冷凝除湿，由于半导体热电芯片的制冷量和制热量相当，当冷凝后的空气经过半导体热电芯片热端加热后可以使其恢复到原来温度，在该空气处理过程中，既可以减少护目镜内部的空气湿度，又能保证护目镜内部的温度不变，进而可以实现等温除湿的目的，同时，该等温除湿过程可以有效地促进护目镜内部空气的流动，避免医护人员的面部不适。The semiconductor thermoelectric chip can realize cooling and heating at the same time. When the temperature of the cold end of the semiconductor thermoelectric chip is lower than the air dew point, the air inside the goggles can be condensed and dehumidified. After the air is heated by the hot end of the semiconductor thermoelectric chip, it can be restored to the original temperature. During the air treatment process, the air humidity inside the goggles can be reduced, and the temperature inside the goggles can be kept unchanged, thereby realizing isothermal dehumidification. At the same time, the isothermal dehumidification process can effectively promote the flow of air inside the goggles and avoid facial discomfort for medical staff.

所述空气处理装置内部的轴流风机和半导体热电芯片均与电源装置连接，通过无级控制旋钮，可以改变轴流风机的转速及半导体热电芯片的制冷量和制热量，以适应医护人员在不同环境下的热舒适要求，其次可以切换制冷制热的模式，实现强化除湿的功能。具体操作是：通过设计的无级控制旋钮，控制电流方向，使得半导体热电芯片下表面制热，上表面制冷，用于加热下方冷凝除湿通道的空气，然后改变电流方向，使得半导体热电芯片下表面制冷，使得热空气与冷表面充分接触除湿，提高除湿效果。The axial flow fan and the semiconductor thermoelectric chip inside the air handling device are both connected to the power supply device. Through the stepless control knob, the rotational speed of the axial flow fan and the cooling capacity and heating capacity of the semiconductor thermoelectric chip can be changed to adapt to medical staff in different situations. The thermal comfort requirements of the environment, and secondly, the cooling and heating mode can be switched to realize the function of strengthening dehumidification. The specific operation is: control the current direction through the designed stepless control knob, so that the lower surface of the semiconductor thermoelectric chip is heated and the upper surface is cooled, which is used to heat the air in the condensing and dehumidifying channel below, and then the current direction is changed, so that the lower surface of the semiconductor thermoelectric chip is heated. Refrigeration makes the hot air fully contact with the cold surface to dehumidify and improve the dehumidification effect.

所述冷凝除湿通道整体向下倾斜，与冷空气流动方向一致，可以有效地减少空气流动阻力，同时，热端表面向上倾斜，空气加热通道的流通截面逐渐缩小，使得半导体热电芯片的热端金属导热板可以对冷空气进行充分加热，避免热空气上浮引起的加热不充分现象，同时，由于空气加热通道的流通截面逐渐缩小，使得空气处理装置送风口的流速增大，进而使得出流风速与护目镜镜框撞击，形成向下的贴附射流，能够有效的避免镜片结露。The condensation and dehumidification channel is inclined downward as a whole, which is consistent with the flow direction of cold air, which can effectively reduce the air flow resistance. The heat-conducting plate can fully heat the cold air to avoid the insufficient heating caused by the hot air floating. The impact of the goggles frame forms a downward attached jet, which can effectively avoid condensation on the lens.

It is bent downward to form a channel-like channel, which is convenient for condensed water to flow from the middle of the arc deflector to the moisture absorption unit.

所述半导体热电芯片可以在传动机构的驱动下进行旋转，以增大半导体热电芯片的倾斜角，进而使得凝结水能够迅速脱落，防止产生膜状凝结，减少湿空气与冷端金属导热板的换热热阻，来增大空气的冷凝除湿效果。The semiconductor thermoelectric chip can be rotated under the drive of the transmission mechanism to increase the inclination angle of the semiconductor thermoelectric chip, so that the condensed water can quickly fall off, prevent film-like condensation, and reduce the exchange of wet air with the cold-end metal heat-conducting plate. Thermal resistance to increase the condensation and dehumidification effect of the air.

所述的一种含有等温除湿功能的护目镜中包含眼镜支架结构，眼镜支架采用橡胶材质，为一对C字型结构，位于护目镜的镜框两侧。在使用时，对于有需要的人群，可以将近视眼镜直接安装在护目镜的眼镜支架上，既减轻了人员负担，又保障了佩戴者眼镜的稳固。The described goggles with isothermal dehumidification function include a spectacles bracket structure, the spectacles brackets are made of rubber and are a pair of C-shaped structures, located on both sides of the frame of the goggles.

The rotation of the axial flow fan inside the air handling device makes the condensation and dehumidification channel in a negative pressure state, and the air heating channel is in a positive pressure state. In the dehumidification channel, the cold air condensed and dehumidified by the cold end of the semiconductor thermoelectric chip enters the air heating channel, and the cold air is heated by the metal heat conducting plate at the hot end to restore it to the inlet temperature, thereby achieving the purpose of isothermal dehumidification.
