Work circuit of intelligent temperature control summer sleeping mat and work method of work circuit

Abstract

The invention relates to a work circuit of an intelligent temperature control summer sleeping mat and a work method of the work circuit. The work circuit comprises a temperature adjusting unit, the temperature adjusting unit comprises an STM8L series low-power-consumption embedded type microprocessor, a hardware interlock circuit and an H-bridge pulse width modulator, and the STM8L series low-power-consumption embedded type microprocessor, the hardware interlock circuit and the H-bridge pulse width modulator are sequentially connected. The microprocessor is respectively connected with a first temperature sensor and a second temperature sensor, the H-bridge pulse width modulator comprises four switch tubes which comprise the first switch tube, the second switch tube, the third switch tube and the fourth switch tube, the first switch tube and the second switch tube are used as an upper half bridge arm, the third switch tube and the fourth switch tube are used as a lower half bridge, the second switch tube and the fourth switch tube are in parallel connection with a power supply unit, and a thermoelectric refrigerating unit is in parallel connection with the first switch tube and the second switch tube. Compared with the prior art, the temperature of the summer sleeping mat with the temperature adjusting unit, the temperature sensors and the thermoelectric refrigerating unit can be flexibly adjusted according to external warm and cold changes, and a user feels warm in winter and cool in summer when lying on the summer sleeping mat.

Description

technical field [0001] The invention relates to a working circuit and a working method of an intelligent temperature-controlled mat, in particular to the field of daily necessities. Background technique [0002] In winter, people often use electric blankets on mattresses to achieve heating and heat preservation. It is bamboo or grass plants, such as carbonized bamboo, subgrass, etc. In addition, there is also a kind of electric mat on the market, which uses electronic refrigeration components or small compressors to cool, absorbs cold through the medium, and uses the pump to transport the medium into the mat to reduce the temperature of the mat's body surface, so that people can lie on it to cool off the heat. purpose of cooling. [0003] In Japan, someone once designed a kind of air-conditioning mat. By placing an exhaust fan at the end of the mat, the air enters through the air inlet on the top of the mat, so that the whole mat can continuously obtain air circulation, th...

[0003] In Japan, someone once designed a kind of air-conditioning mat. By placing an exhaust fan at the end of the mat, the air enters through the air inlet on the top of the mat, so that the whole mat can continuously obtain air circulation, thereby keeping the mat further refreshing. How much noise affects user comfort

Patent No.: 200520142848, patent name: a water mat, which is composed of upper and lower layers of PVC calendered film, which is formed by a heat sealing machine and a special mold to form a row of sealing rings or partially pressed rings, which can be formed after water injection Rows of neat and consistent water bags, the sealing ring can be removed to increase the air flow, and if part of the press can hold more water, it can absorb body temperature continuously in summer and make sleep more comfortable, but this water mat can only use in summer

[0004] In summary, the current mat does not have the ability to reduce the surface temperature of the mat body in hot summer and increase the temperature of the mat body surface in cold winter
