The refrigeration or heating will be described below:
Embodiment one:
the filter type mask structure for the refrigeration mask used in summer:
Specifically, this embodiment discloses a mask structure that is used in cooperation with a medical mask, which is designed mainly for bacteria breeding caused by higher temperature of wearing position when wearing the mask in hot summer, poor comfort, and skin allergy, firstly, the general use condition of the mask structure is that a user wears the medical mask first, then wears the mask structure at the front end of the medical mask, when in use, a power line 404 for semiconductor refrigeration is connected with an external rechargeable battery power supply device, such as a mobile power supply, the semiconductor refrigeration is powered by the power supply device, and the semiconductor refrigeration is performed, and the air inlet 203 of the mask body 1 of this embodiment is used for the intake of external air during inspiration, because the temperature of the external air in hot summer is also higher, the semiconductor refrigeration sheet of this embodiment is not only used for cooling the temperature in the respiratory cavity, but also simultaneously dissipates the heat in the external air, and the cooled air enters the mask body 1 from the first respiratory tube 2, and is finally inhaled by the user through the medical mask; in addition, the mask body 1 of this embodiment further has an air outlet, which is mainly the discharge of the exhaled air during exhalation, and the air inlet 203 and the air outlet are separately designed, so that the workload of the semiconductor refrigeration sheet can be reduced, and the technical problem that the use effect is poor due to the mixing of the high-temperature air and the low-temperature air in the first respiratory tube 2 is avoided.
Embodiment two:
mask structure for filter type heating mask used in winter:
specifically, this embodiment discloses a mask structure that cooperates with a medical mask, which is designed mainly for the problem of poor comfort level caused by low temperature of wearing position when wearing the mask in cold winter, firstly, the general use condition of the mask structure is that a user wears the medical mask first, then wears the mask structure at the front end of the medical mask, when in use, the power line 404 of a semiconductor heating sheet is connected with an external rechargeable battery power supply device, such as a mobile power supply, and the power supply device supplies power to the semiconductor heating sheet and heats the semiconductor heating sheet, the air inlet 203 of the mask body 1 of this embodiment is used for the entry of external air when inhaling, and the semiconductor heating sheet heats the air to enter the mask body 1 from the first breathing tube 2 and is finally inhaled by the user through the medical mask; in addition, the mask body 1 of the present embodiment also has an air outlet, which is mainly the discharge of exhaled air during exhalation.
The structure is similar to that of the first embodiment, so the structure is not repeated, but is different from the use environment of the first embodiment, and the second embodiment is used in cold winter, so the second embodiment selects the semiconductor heating sheet, which can raise the temperature of the sucked air during suction. Other structures and functions are similar to those of the embodiments.
The semiconductor refrigerating or heating sheet is characterized in that: when the direction of the positive electrode and the negative electrode of the power supply is changed, the original refrigerating surface is changed into a heating surface; the heat radiation surface becomes a heat radiation surface, so the mask structure for the filtering type refrigeration mask can be used as a mask for the filtering type heating mask or a mask for the refrigeration mask by reversing the positive electrode and the negative electrode of the power supply.
