[0071] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0072] like Figure 1-4 As shown in the embodiment of this application, a waste heat recovery system for an electric motor is proposed, comprising: a waste heat collection module 100, which is used for heat exchange with the motor casing, and includes a cold working fluid circulation pipeline 110; a waste heat recovery module 200, which is connected to the cold working fluid circulation pipeline 110 of the waste heat collection module 100, and recovers the heat energy collected by the cold working fluid circulation pipeline 110; and a heating module 300, which includes a hot working fluid circulation pipeline 310 connected to the waste heat recovery module 200; the heating module 300 further includes a first electric valve 320 and an electric heating circuit 330, wherein the first electric valve 320 is disposed in the hot working fluid circulation circuit and has an adjustable opening degree, and the electric heating circuit 330 has a power supply 331 with adjustable power.

[0073] The waste heat recovery and utilization system for electric motors provided in this application includes a waste heat collection module 100, a waste heat recovery module 200, and a heating module 300.

[0074] The waste heat collection module 100 is used to exchange heat with the motor housing and includes a cold working fluid circulation pipe 110. In actual use, the cold working fluid circulation pipe 110 flows through the motor housing of the cigarette machine. The working fluid in the cold working fluid circulation pipe 110 exchanges heat with the motor housing, so that the cold working fluid circulation pipe 110 absorbs heat energy and cools down the motor housing at the same time.

[0075] Among them, the waste heat recovery module 200 is used to recover the heat energy absorbed by the cold working fluid circulation pipeline 110 in the waste heat collection module 100, so as to cool down the cold working fluid circulation pipeline 110 and put it into the next cycle to absorb the heat energy of the motor casing.

[0076] The heating module 300 is connected to the waste heat recovery module 200. The heating module 300 has a heat working fluid circulation pipeline 310. The heating module 300 absorbs the heat energy recovered by the waste heat recovery module 200 through the heat circulation pipeline and converts the heat energy into electrical energy.

[0077] The heating module 300 further includes a first electric valve 320 and an electric heating circuit 330. The first electric valve 320 is disposed in the heat medium circulation pipeline 310. The first electric valve 320 can be adjusted to regulate the flow rate of the heat medium circulation pipeline 310, thereby adjusting the rate at which the heating module 300 converts heat energy into electrical energy. The heating module 300 provides the electrical energy converted from heat energy to the electric heating circuit 330, which then converts the electrical energy back into heat energy to heat the cigarette machine components that need to be heated.

[0078] This waste heat recovery system is mainly used inside cigarette machines. It receives waste heat from the motor casing via a fluid medium. The streamlined structure reduces the required space, allowing the system to be installed inside the cigarette machine. This achieves the recovery and utilization of waste heat from the motor casing, saving energy and reducing production costs. While recovering waste heat from the motor casing, this technical solution also cools the motor casing using a fluid medium, effectively preventing the motor from overheating and improving the production efficiency of the cigarette machine. Furthermore, this technical solution can precisely control the temperature provided by the electric heating circuit 330 by adjusting the opening of the first electric valve 320 and the efficiency of the electric heating circuit 330. If the temperature of the electric heating circuit 330 is too high, the opening of the first electric valve 320 can be adjusted; if the temperature of the electric heating circuit 330 is too low, power can be supplied to the electric heating circuit 330 via the power supply 331 to increase the temperature.

[0079] like Figure 1-4 As shown, the waste heat collection module 100 further includes: a heat collection component 120, which is disposed in the motor housing and connected to the cold working fluid circulation pipeline 110; and a cold working fluid pump 130, which is disposed in the cold working fluid circulation pipeline 110 and is used to provide power for the flow of working fluid in the cold working fluid circulation pipeline 110.

[0080] In this technical solution, the waste heat collection module 100 also includes a heat collection module and a cold working fluid pump 130. The heat collection module is connected to the cold working fluid circulation pipeline 110 and acts on the motor housing. The heat collection module is located close to the motor housing, so that heat exchange between the cold working fluid circulation pipeline 110 and the motor housing can be realized.

[0081] The cold working fluid pump 130 is used to provide power for the flow of working fluid in the cold working fluid circulation pipeline 110. At the same time, adjusting the flow rate of the cold working fluid pump 130 can adjust the flow rate of the cold working fluid circulation pipeline 110, thereby adjusting the heat exchange efficiency of the cold working fluid circulation pipeline 110.

[0082] like Figure 1-4 As shown, the waste heat recovery module 200 includes: a working fluid storage tank 210, which contains a heat exchange working fluid; a compressor 220, through which the heat exchange working fluid flowing out of the working fluid storage tank 210 is compressed; an evaporator 230, connected to a cold working fluid circulation pipeline 110, through which the compressed heat exchange working fluid from the compressor 220 enters the evaporator 230, which evaporates the heat exchange working fluid from a liquid state to a gaseous state and absorbs the heat energy from the cold working fluid circulation pipeline 110; and a gas collector 240. 40 is connected to the evaporator 230, and the gas collector 240 is used to collect the gaseous heat exchange medium; the condenser 250 is connected to the gas collector 240 and the heat exchange medium circulation pipeline 310. The condenser 250 is used to condense the gaseous heat exchange medium into a liquid state, and the heat energy released during the condensation process is absorbed by the heat exchange medium circulation pipeline 310. The condenser 250 is connected to the heat exchange medium storage tank 210, and the heat exchange medium after condensation into a liquid state is recovered to the heat exchange medium storage tank 210.

[0083] In this technical solution, the waste heat recovery module 200 includes a working fluid storage tank 210, an evaporator 230, a gas collector 240, and a condenser 250.

[0084] During operation, the working fluid in the working fluid storage tank 210 flows into the evaporator 230, where it evaporates. During this process, the heat energy of the cold working fluid circulation pipe flowing through the evaporator 230 is absorbed. The gas collector 240 recovers the gaseous working fluid flowing out of the evaporator 230, thus achieving stable gas flow and sending the gas with a stable flow rate into the cooler. The condenser 250 condenses the gaseous working fluid into a liquid working fluid. During this process, the hot working fluid circulation pipe 310 flowing through the condenser 250 absorbs the heat released during the condensation of the gaseous working fluid, thus raising the temperature of the hot working fluid circulation pipe 310. After flowing out of the condenser 250, the liquid working fluid returns to the working fluid storage tank 210, completing one cycle.

[0085] Through the above process, the waste heat recovery module 200 achieves the cooling of the cold working fluid circulation pipe and the heating of the hot working fluid circulation pipe. At the same time, compared with the direct contact between the cold working fluid circulation pipe 110 and the hot working fluid circulation pipe 310, this technical solution effectively improves the heat exchange efficiency.

[0086] like Figure 1-4 As shown, the working fluid storage tank 210 includes: a tank body 211 for storing the heat exchange working fluid; a working fluid inlet 212 disposed in the tank body 211 and connected to the condenser 250; a working fluid outlet 213 disposed in the tank body 211 and connected to the compressor 220; a feed port 214 disposed in the tank body 211 for replenishing the heat exchange working fluid; a vent valve 215 disposed in the tank body 211 for discharging the heat exchange working fluid; and a level sensor 216 disposed in the tank body 211.

[0087] In this technical solution, the working medium storage tank 210 has a feed port 214, a vent valve and a liquid level sensor 216. When the liquid level sensor 216 detects that the liquid level is too high, a portion of the working medium can be discharged through the vent valve. When the liquid level sensor 216 detects that the liquid level is too low, the working medium can be replenished through the feed port 214.

[0088] like Figure 1-4 As shown, the waste heat recovery module 200 further includes a second electric valve 260, which is disposed between the working fluid outlet 213 and the compressor 220.

[0089] In this technical solution, the waste heat recovery module 200 also includes a second electric valve 260, which is used to provide power for the flow of working fluid within the waste heat recovery module 200.

[0090] like Figure 1-4 As shown, the heating module 300 further includes: a heat pump 340, which is disposed in the heat circulation pipeline 310; a first thermoelectric generator 350, which is disposed in the heat circulation pipeline 310; and a second thermoelectric generator 360, which is disposed in the heat circulation pipeline 310.

[0091] In this technical solution, the heating module 300 also includes a heat working fluid pump 340, a first thermoelectric generator 350, and a second thermoelectric generator 360. During use, the heat working fluid pump 340 is used to provide power for the flow of working fluid in the heat working fluid circulation pipe, and the first thermoelectric generator 350 and the second thermoelectric generator 360 are used to convert the heat energy in the heat working fluid circulation pipe 310 into electrical energy.

[0092] like Figure 1-4 As shown, the electric heating circuit 330 further includes: a first heating coil 332, which is electrically connected to a first thermoelectric generator 350; a second heating coil 333, which is electrically connected to a second thermoelectric generator 360; a power supply 331, which is electrically connected to the first thermoelectric generator 350 and the second thermoelectric generator 360; and a controller 334, which is electrically connected to the power supply 331 and is used to control the power output of the power supply 331 to the first heating coil 332 and the second heating coil 333, respectively.

[0093] In this technical solution, the electric heating circuit 330 also includes a first heating coil 332, a second heating coil 333, and a controller 334.

[0094] The first heating coil 332 is electrically connected to the first thermoelectric generator 350, and the second heating coil 333 is electrically connected to the second thermoelectric generator 360. The first heating coil 332 and the second heating coil 333 are initially powered by the first thermoelectric generator 350 and the second thermoelectric generator 360. When the power output of the first thermoelectric generator 350 and the second thermoelectric generator 360 is insufficient, resulting in the temperature of the first heating coil 332 and the second heating coil 333 not meeting the standard, the power supply 331 supplements the power. The power output of the power supply 331 is controlled by the controller 334, thereby achieving precise control of the temperature of the first heating coil 332 and the second heating coil 333.

[0095] like Figure 1-4 As shown, the waste heat recovery module 200 further includes: a first temperature sensor 140, which is disposed in the cold working fluid circulation pipeline 110 and is used to monitor the working fluid temperature in the cold working fluid circulation pipeline 110.

[0096] In this technical solution, the first temperature sensor 140 is used to monitor the temperature of the working fluid in the refrigerant circulation pipeline 110. When the temperature of the first temperature sensor 140 exceeds the threshold, the refrigerant circulation management cannot effectively exchange heat with the compressor 220 casing, which can be inferred to be a malfunction of the waste heat recovery module 200. At this time, the staff can be reminded to carry out maintenance in time.

[0097] like Figure 1-4 As shown, the heating module 300 further includes: a second temperature sensor 370, which is disposed in the heat working fluid circulation pipeline 310 and at the front end of the first thermoelectric generator 350; and a third temperature sensor 380, which is disposed in the heat working fluid circulation pipeline 310 and at the rear end of the first thermoelectric generator 350 and the front end of the second thermoelectric generator 360.

[0098] In this technical solution, the heating module 300 also includes a second temperature sensor 370 and a third temperature sensor 380. The second temperature sensor 370 is used to measure the temperature of the working fluid that is about to flow into the first thermoelectric generator 350, and the power that the first thermoelectric generator 350 can generate can be determined based on this temperature. The third temperature sensor 380 is used to measure the temperature of the working fluid that is about to flow into the second thermoelectric generator 360, and the power that the second thermoelectric generator 360 can generate can be determined based on this temperature. When it is determined that the power output by the first thermoelectric generator 350 or the second thermoelectric generator 360 exceeds a threshold, the opening of the second electric valve 260 can be adjusted, thereby adjusting the flow rate of the working fluid circulation pipeline 310, and thus reducing the power output by the first thermoelectric generator 350 and the second thermoelectric generator 360.

[0099] like Figure 1-4 As shown, the heat collection assembly 120 includes: a liquid inlet connected to the refrigerant circulation pipeline 110; a fluid channel, one end of which is connected to the liquid inlet and arranged around the periphery of the motor housing; and a liquid outlet connected to the other end of the fluid channel and connected to the refrigerant circulation pipeline 110.

[0100] In this technical solution, the heat collection component 120 includes a liquid inlet, a fluid channel, and a liquid outlet. The fluid channel is arranged around the motor, which serves to both exchange heat for the motor casing and cool the motor during the heat exchange process.

[0101] In this embodiment, the high-power motor of the cigarette machine is integrated into a back cavity of the device, and the fluid channels are arranged inside the back cavity and on the cover plate of the back cavity.

[0102] like Figure 1-4 As shown, the waste heat collection module 100 further includes: a fourth temperature sensor, which is used to measure the temperature of the motor housing. The fourth temperature sensor is electrically connected to the refrigerant pump 130. When the temperature of the motor is below a threshold range, the refrigerant pump 130 stops operating, and when the temperature of the motor is above the threshold range, the refrigerant pump 130 starts.

[0103] The optimal operating temperature for an electric motor is typically between 30 and 40 degrees Celsius. Within this temperature range, wear and tear on the motor's mechanical components and thermal expansion and contraction can be effectively controlled. When the motor operates below 30 degrees Celsius, firstly, further cooling is unnecessary; secondly, due to the lower temperature difference, the heat exchange efficiency between the refrigerant circulation pipe 110 and the motor casing decreases. Therefore, a fourth temperature sensor is added to measure the motor's operating temperature. This fourth temperature sensor is electrically connected to the refrigerant pump 130. When the fourth temperature sensor detects that the motor casing temperature is below a threshold, the refrigerant pump 130 stops operating.

[0104] like Figure 1-4 As shown, a cigarette rolling machine includes: a cigarette rolling machine body, the cigarette rolling machine body including an electric motor; an electric motor back cavity, the electric motor in the cigarette rolling machine body being disposed in the electric motor back cavity; a motor waste heat recovery and utilization system as described above; the waste heat collection module 100 acting on the electric motor back cavity; a cigarette paper gluing assembly, the heating module 300 acting on the cigarette paper gluing assembly; and a glue cylinder, the heating module 300 acting on the glue cylinder.

[0105] In this technical solution, a cigarette rolling machine includes a cigarette rolling machine body, a motor back cavity, a cigarette paper gluing assembly, and a glue cylinder.

[0106] The cigarette machine body has multiple motors, and the motor back cavity integrates the high-power motor of the cigarette machine. The waste heat collection module 100 acts on the motor back cavity to realize heat exchange between the motor shell and the cold working fluid circulation pipeline 110. In this embodiment, specifically, the heat collection component 120 is set in the motor back cavity.

[0107] The cigarette paper gluing assembly is used to bond the cigarette paper after rolling. To prevent the adhesive from solidifying, the assembly needs to be continuously heated; however, to prevent the adhesive from deteriorating, the heating temperature cannot be too high. Meanwhile, the glue tank is used to store and supply glue to other processes, such as the bonding of the filter tip to the cigarette body; its requirements are the same as those of the cigarette paper gluing assembly.

[0108] In this embodiment, the recovered waste heat energy is used to continuously heat the tobacco paper gluing assembly and the glue cylinder through the electric heating circuit 330. By adjusting the opening degree of the first electric valve 320 and the output power of the power supply 331, the tobacco paper gluing assembly and the glue cylinder are stabilized within a certain temperature range.

[0109] This technical solution realizes the recovery and secondary utilization of waste heat from the motor of the cigarette machine, saving energy and reducing production costs. At the same time, the adjustable power of the power supply 331 of the first electric valve 320 and the electric heating circuit 330 meets the temperature requirements of the gluing assembly and the glue cylinder of the cigarette paper.
