The Bluetooth-supported air conditioner is communicated with electronic equipment supporting Bluetooth signals, has the functions of receiving control commands, controlling the operation of a fan and collecting sensor data and transmitting the sensor data, and realizes that the air supply of different air distribution channels of the air conditioner is independently adjustable. The user controls the start and stop and the rotating speed of the air supply fan 42 through the Bluetooth connection electric control device 47 of the mobile phone, and reads the data measured by the detection sensor 46. The electric control device 47 and the heat exchange core 43 are arranged in the air supply shell together, so that the overheat of the electric control device 47 can be avoided by utilizing the emitted cold energy of the heat exchange core 43.
The electric control cavity 406 is communicated with the detection cavity 407 through wires, and the detection sensor 46 is used for detecting the temperature and humidity of the air outlet; the electric control cavity 406 is also in wire communication with the air inlet cavity 401 and is connected with the air supply fan 42 for controlling the switch and the rotating speed of the air supply fan 42. When the heat exchange inner core 43 is frozen, that is, the cold accumulation material in the heat exchange inner core is cooled, the heat exchange inner core is placed in the heat exchange cavity 402, and is covered with the heat preservation cover and then is matched and connected with the Bluetooth module in the electric control cavity 406 through the Bluetooth of the mobile phone. The handset then sends a fan on signal and the blower fan 42 is turned on. When in use, external hot air firstly passes through the air inlet and is sucked into the heat exchange cavity 402 through the air supply fan 42, and then is subjected to heat exchange and temperature reduction through the surface of the copper pipe of the heat exchange inner core 43, so that redundant water is separated out, and then is sent out through the air outlet. The signals obtained by the detection sensor 46 are continuously sent back to the mobile phone through the Bluetooth module, so that the mobile phone can read real-time air supply temperature and humidity and can also send signals to change the rotating speed of the fan, and the cooling capacity is changed. At the later stage of the working process, the external hot air continuously exchanges heat with the copper pipe wall of the heat exchange inner core 43, the temperature of the phase change material in the copper pipe continuously rises, and finally the cooling capacity is exhausted, and at the moment, the air supply fan 42 is required to be closed, and the heat exchange inner core 43 is taken out for refreezing.

The phase change material is not limited to a certain defined substance, and its phase change temperature is 0 ℃.
The heat exchange core 43 further comprises an upper clamping plate 434, and a round hole matched with the outer diameter of the heat exchange tube 431 is formed in the upper clamping plate 434. The top ends of the heat exchange tubes 431 are opened, the top of each heat exchange tube 431 is respectively penetrated into the corresponding round hole, and the upper clamping plate 434 is used as a support. The top end of the heat exchange tube 431 is flush with the top surface of the upper clamping plate 434, the bottom end of the heat exchange tube 431 is sealed, and the heat exchange tube 431 is fixedly connected with the upper clamping plate 434 and the lower bottom plate 433 through strong glue. The sealing top plate 432 is covered on the upper clamping plate 434. The sealing top plate 432 is made of flexible material with viscosity, waterproof sealant can be selected, the heat exchange inner core 43 is of a copper tube bundle structure, and can be used for sealing the copper tube after the copper tube is filled with water and can adapt to volume expansion after the water is frozen into ice.
The water is used as the phase-change material, the phase-change latent heat is 330KJ/Kg, and the water-based phase-change material can store larger cold energy and is safe and nontoxic. One end of the copper tube bundle structure is sealed with a phase change material by using waterproof sealant capable of bearing deformation so as to adapt to the volume change caused by the phase change. The heat exchange core 43 is of an independent structure, and the phase change material therein is easy to detach after cooling and refrigerates the heat exchange core 43.
The air supply mechanism is placed in the backpack 50 and detachably connected with the inner side wall of the backpack 50, and the air supply shell 40 can be fixed on the backpack 50 by nylon buckles or magic tapes. The bottom of the backpack 50 is provided with an air inlet hole which is used for being communicated with the outside; because the total air quantity of the air blower 42 is not large, the air quantity entering through the air inlet hole at the bottom of the backpack 50 is kept enough, so that the normal use of the air blower 42 is not affected due to the pressure difference formed between the inside and the outside of the schoolbag. The design has the advantages that the air sucked by the air supply fan 42 is the air with lower temperature inside the backpack 50, but not the air with higher external temperature, so that the service time of the heat exchange inner core 43 can be prolonged; in principle, the phase change material in the heat exchange core 43 of the air treatment device is reused by heat conduction to cool the air in the backpack 50. The air outlet is communicated with the air inlet through a connecting pipe, and the knapsack 50 is also provided with a perforation for the connecting pipe to extend out of the knapsack 50. The back strap 51 of the backpack 50 is provided with a penetration hole through which the connection pipe is penetrated in the extending direction thereof, so that the front air supply duct for connecting the first and second air supply holes is hidden in the back strap 51. The left and right sides of knapsack 50 back installs the bodiness cushion 52 respectively, makes knapsack 50 and user's back exist great space, and the user's back spine vicinity is the non-pressurized district when using, prevents knapsack 50 oppression air conditioning clothes influence back air supply, guarantees that the air conditioning clothes is unobstructed in the cloth wind channel air current of back.
Before the invention is used, the two heat exchange inner cores 43 are detached and placed in a refrigerating device such as a refrigerator, a freezer and the like to be refrigerated, so that the phase change material in the heat exchange inner cores 43 is subjected to phase change, and the cold energy is stored.
During the wearing process, the heat exchange inner core 43 is arranged in the air treatment device, the shell cover 41 is covered to fasten the nylon button, and the heat exchange inner core is arranged in the special backpack 50. After the user wears the air-conditioning coat back pack 50, the magnetic interface 60 can be connected by himself or herself until the wearing process is completed. After the opening rate of the front fan and the rear fan is input through the Bluetooth module of the mobile phone Bluetooth connection air treatment device, the air supply fan 42 in the air supply shell 40 starts to operate, external hot air is sucked, heat exchange is carried out through copper bundles of the heat exchange inner core 43, condensed water separated out in the air is collected into the condensed water tank cavity 403, and the treated proper air enters the air distribution pipeline of the air conditioning clothes through the air supply pipeline, so that the whole air flue is swelled to form certain static pressure, the air supply quantity is uniformly distributed in each air supply micropore 221, and the air supply of the part responsible for each air flue is uniform. The condensed water is separated out from the treated air, so that the heat exchange between the skin side of the human body and the human body is carried away to a certain extent, and the liquid diaphoresis of the human body is taken away, so that the stuffiness is relieved. Because the front air duct and the rear air duct supply air independently, a user can adjust the air supply quantity of the front air duct and the rear air duct according to the cold and hot requirements of the user, so that all parts of a human body can meet the heat dissipation requirements. The bluetooth module of the electric control device 47 can transmit back the information such as the temperature and humidity of the air supply, the residual electric quantity and the cold quantity in real time for the reference of the user.
