Description

Technical Field

[0001] This invention relates to the field of ointment storage cabinets, and more particularly to an intelligent medicine management cabinet and management method. Background Technology

[0002] As a commonly used topical medication in clinical practice, ointments generally need to be cooled and solidified as soon as possible after preparation before storage. Currently, ointment storage mostly relies on ordinary medicine cabinets, refrigerators, or simple fume hoods, with overall air cooling as the primary method. This only provides a rough cooling of the cabinet environment and cannot achieve direct heat conduction and dissipation from the medicine boxes. Heat tends to accumulate at the bottom of the medicine boxes, resulting in slow and uneven cooling. At the same time, traditional equipment has passive refrigerant circulation and the flow rate cannot be adaptively adjusted. Under high-temperature conditions, refrigerant replenishment is delayed, pressure fluctuations are large, and local overheating is likely to occur. The airflow organization within the cabinet is chaotic, the cold air diffusion efficiency is low, and the cooling effect of the upper and lower medicine boxes differs significantly. In addition, existing equipment lacks zoned real-time temperature measurement, intelligent start-stop, and high-temperature emergency control functions. The level of intelligence is low, the temperature control accuracy is poor, and the energy consumption is high, making it difficult to meet the needs of rapid cooling, constant temperature preservation, and stable storage of ointments, thus restricting the quality control level of ointment production and storage. Therefore, we propose an intelligent medicine management cabinet and management method to solve the above-mentioned problems. Summary of the Invention

[0013] A preferred method for intelligent drug management is characterized by:

[0014] S1. Power-on initialization and refrigerant pre-charge:

[0015] S1.1 When the power is turned on, the cabinet will automatically perform a self-test, and the temperature sensor, pump set, cooling chip, and valve body will enter standby mode.

[0016] S1.2, The pump unit starts, and the refrigerant in the bottom storage tank is transported to each plate rack compartment through the discharge pipe, riser, valve body and conduit 2. Then it is evenly filled into the refrigeration pipe through the through pipe to complete the pre-charge of the refrigerant circuit.

[0017] S1.3 After pre-charging is completed, the controller enters standby mode. When the temperature is lower than the preset threshold, the pump unit and the cooling chip stop operating.

[0018] S2. Temperature monitoring and intelligent start / stop control:

[0019] S2.1 Temperature sensors on the front of each shelf collect the real-time temperature of the medicine box and the environment inside the cabinet;

[0020] S2.2 Temperature Judgment Rules:

[0021] ① Temperature 10°C higher than the boiling point of the refrigerant: This is considered a high temperature. The pump unit and the cooling coil will operate at full power to accelerate the refrigerant circulation.

[0022] ② When the temperature is near the boiling point of the refrigerant: the refrigerant absorbs heat and evaporates, then enters a natural circulation to dissipate heat;

[0023] ③ When the temperature is lower than the preset safety value: the pump unit and cooling coils stop, and the refrigerant remains stationary to maintain its temperature;

[0024] S2.3 Temperature data is fed back in real time, and the controller automatically adjusts the cooling power to maintain a constant temperature environment for ointment storage;

[0025] S3, Core Cooling and Heat Dissipation Management:

[0026] S3.1 Direct heat conduction cooling: The bottom of the medicine box is in close contact with the top plate. Heat is conducted to the refrigerant in the middle compartment through the heat conduction column, sleeve and heat conduction plate. The refrigerant absorbs heat quickly and achieves direct cooling of the medicine box.

[0027] S3.2 Ambient cooling: The cooling pipes are distributed on the outside of the plate frame to continuously cool the air around the medicine box, forming an ambient cooling environment to accelerate the cooling and molding of the ointment;

[0028] S3.3 Refrigerant Circulation and Regeneration: The refrigerant absorbs heat and evaporates into a gaseous state. The pressure in the middle compartment and the refrigeration pipe increases. The gaseous refrigerant flows through the conduit to the connecting pipe, enters the condenser pipe, and condenses into a liquid state with the assistance of the refrigeration plate. It then flows back to the pump group storage tank to achieve recycling.

[0029] S4. High-Temperature Emergency and Adaptive Flow Management:

[0030] S4.1 When the temperature of the ointment is too high, causing the refrigerant to sublimate rapidly and the pressure of the refrigeration pipe to increase sharply: some gaseous refrigerant enters the impeller chamber through the second connecting hose, which drives the second impeller to rotate, and drives the second rotating pipe and the guide vane to rotate, accelerating the speed at which the refrigerant flows into the middle chamber and quickly replenishing the refrigerant to cope with the high temperature;

[0031] S4.2 The gas in the wheel compartment returns to the refrigeration pipe through the connecting hose, completing a local small circulation and ensuring stable pressure;

[0032] S5, Airflow-linked heat dissipation management:

[0033] S5.1 When the gaseous refrigerant flows through the duct, it impacts the impeller, which drives the rotating pipe and the fan to rotate, disturbing the air inside the cabinet and spreading the cold air from the cooling pipe and the top plate to the whole cabinet, thus improving the overall heat dissipation efficiency.

[0034] S5.2 The fan airflow passes through the opening of the stand and impacts the inclined guide plate at the bottom of the top plate, which drives the top plate, heat conduction column and bottom fan blades to rotate, further enhancing the airflow at the lower medicine box and accelerating heat dissipation;

[0035] S6. Routine Maintenance and Management:

[0036] S6.1 Regularly check the refrigerant level and replenish it to the standard level if it is insufficient;

[0037] S6.2 Clean the dust from the vents of the rack and the surface of the cooling pipes to ensure heat conduction and ventilation efficiency;

[0038] S6.3 Verify the accuracy of the temperature sensor to ensure accurate temperature control; check the operating status of the pump set, cooling coil, and valve body, and replace faulty parts in a timely manner.

[0039] S6.4 Keep the cabinet door closed to reduce cold loss and lower controller energy consumption;

[0040] S7, Power Off Management:

[0041] S7.1 First, remove the medicine from the cabinet and close the cabinet door;

[0042] S7.2 Press the power off button, the pump unit and cooling coils will stop running, and the refrigerant will flow back to the storage tank;

[0043] S7.3 After the controller completes refrigerant recovery, disconnect the main power supply.

[0044] Compared with the prior art, the present invention has the following beneficial effects:

[0045] 1. The pump unit inside the bottom compartment can input refrigerant into the riser through the discharge pipe. The valve body on the riser can input the refrigerant into each conduit 2. The conduit 2 can then guide the refrigerant into the middle compartment. The through pipe can further guide the refrigerant into the refrigeration pipe. The top plate, which is close to the bottom of the medicine box, can conduct the heat on the medicine box to the heat-conducting plate through the heat-conducting column and sleeve, thereby heating the refrigerant. The refrigerant inside the middle compartment can quickly absorb heat through the refrigeration pipe, thereby achieving automatic cooling and maintaining a suitable temperature for the medicine box. It can also absorb heat and cool the heat-conducting column and top plate. The top plate can directly dissipate heat and cool the medicine box, and the refrigeration pipe can cool the surrounding environment of the medicine box. This allows the temperature of the medicine box and the ointment inside to drop more quickly, which is beneficial for the cooling and shaping of the ointment and subsequent storage.

[0046] 2. When the temperature of the medicine box and its surroundings decreases, the refrigerant in the cooling pipes and the middle compartment tends to stabilize. Under normal conditions, the refrigerant will remain in the middle compartment and inside the cooling pipes, continuously dissipating heat. When the temperature conducted from the medicine box reaches the boiling point of the refrigerant, the refrigerant will quickly absorb heat and evaporate into a gaseous state. At this time, the pressure inside the cooling pipes and the middle compartment increases, and some of the gas will flow through the conduit into the connecting pipe. Then, the gaseous refrigerant can be condensed by the condenser, thus enabling the refrigerant to be recycled. The cooling element can increase the condensation effect and condensation speed of the condenser, facilitating the rapid recovery of the refrigerant. This is beneficial for the storage of ointments inside the ointment storage cabinet and for its continuous use.

[0047] 3. When the temperature of the ointment is too high, causing the refrigerant in the cooling pipe and the middle compartment to sublimate too quickly, resulting in increased pressure inside the cooling pipe, some gas will enter the wheel compartment through the second connecting hose. This will drive the impeller inside the wheel compartment to rotate. The impeller will then drive the rotating connecting pipe and the guide vane fixed to the rotating connecting pipe to rotate. The rotation of the guide vane will accelerate the speed at which the refrigerant enters the middle compartment, achieving rapid replenishment of the refrigerant inside the middle compartment. This is beneficial for dealing with the high temperature of the ointment, thereby achieving continuous and uninterrupted cooling of the medicine box, which is beneficial for practical use.

[0048] 4. The gas entering the chamber will be discharged back to the other end of the refrigeration pipe through the connecting hose. Most of the gas inside the refrigeration pipe will be collected directly into the connecting pipe through the conduit. During this process, the pressure of the gas flow will impact the impeller, thereby driving the rotating pipe and the fan to rotate. The rotation of the fan can disturb the air inside the cabinet, forming an airflow, which can further dissipate heat from the medicine box and the ointment inside, and can also distribute the cooler air at the refrigeration pipe and the top plate to the rest of the space inside the cabinet, making the heat dissipation efficiency higher and helping to deal with the situation of heat accumulation.

[0049] 5. When the fan starts to rotate rapidly, the airflow generated by the fan will pass through the opening and impact the inclined guide plate at the bottom of the top plate, thereby driving the top plate to rotate. The rotation of the top plate will drive the heat conduction column and the fan blades at the bottom of the heat conduction column to rotate. The rotation of the fan blades will drive the surrounding air to flow. At the same time, the fan blades can also disperse the cooler air at the cooling pipe and achieve heat dissipation for the lower medicine box and the ointment inside. Attached Figure Description

[0060] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0061] like Figures 1-9 The illustrated intelligent medicine management cabinet includes a medicine ointment storage cabinet 1, which includes a cabinet body 101. Cabinet doors 103 are hinged to both sides of the front of the cabinet body 101. Uprights 107 are fixedly connected to both sides of the inner middle of the cabinet body 101. Evenly distributed shelves 104 are fixedly connected to the inner sides of the uprights 107. Medicine boxes 102 are installed on the top of each shelf 104. A central compartment 125 is installed in the middle of each shelf 104. Multiple connecting pipes 123 are fixedly connected to the outer periphery of each central compartment 125. Multiple cooling pipes 122 are connected to the outer periphery of each central compartment 125 via the connecting pipes 123. The cooling pipes 122 are installed on the outer side of the middle of each shelf 104. A sleeve 132 is installed in the middle of each central compartment 125. Heat-conducting plates 129 are fixedly connected to the outer periphery of each sleeve 132. The heat-conducting plates 129 are located in the middle of each central compartment 125.

[0062] Furthermore, in specific implementation, the prepared ointment can be stored in the medicine box 102 inside the ointment storage cabinet 1. When the ointment is placed in the ointment storage cabinet 1, the dissipated heat will gradually accumulate in the windless environment, causing the interior of the cabinet 101 to reach a high temperature, affecting the cooling, shaping, and storage of the ointment. In actual use, the pump unit 112 inside the bottom compartment 105 can input refrigerant through the discharge pipe 113 into the riser pipe 118. The refrigerant can be tetrafluoroethane. The valve body 117 on the riser pipe 118 can input the refrigerant into each conduit 114. The refrigerant is then introduced into the middle compartment 125 through the conduit 114. Pipe 123 can further introduce refrigerant into the interior of refrigeration pipe 122. Through the top plate 115 tightly attached to the bottom of the medicine box 102, the heat on the medicine box 102 can be conducted to the heat-conducting plate 129 through the heat-conducting column 130 and the sleeve 132, thereby heating the refrigerant. The refrigerant inside the refrigeration pipe 122 and the middle compartment 125 can quickly absorb heat, thereby achieving automatic cooling. It can also absorb heat and cool the heat-conducting column 130 and the top plate 115. The top plate 115 can directly dissipate heat and cool the medicine box 102. The refrigeration pipe 122 can cool the surrounding environment of the medicine box 102, thereby enabling the working temperature of the medicine box 102 to drop to the appropriate threshold more quickly.

[0063] Each of the refrigeration pipes 122 is fixedly connected to a conduit 109 on one side. The end of each conduit 109 away from the refrigeration pipe 122 is fixedly connected to a connecting pipe 108. The connecting pipe 108 is installed in the middle of one side of the cabinet 101. A condenser pipe 119 is fixedly connected to the bottom of the connecting pipe 108. A pump set 112 is fixedly connected to the other end of the condenser pipe 119. The pump set 112 is connected to a controller, which is electrically connected to a temperature sensor. A discharge pipe 1 is fixedly connected to the output end of the pump set 112. 13. The end of the discharge pipe 113 away from the pump group 112 is fixedly connected to a riser pipe 118. The riser pipe 118 is installed inside the side chamber 106. The side chamber 106 is fixedly connected to the side of the cabinet 101 away from the connecting pipe 108. Multiple valve bodies 117 are installed in the middle of the riser pipe 118. The valve body 117 is a one-way valve. A second guide pipe 114 is installed on one side of each valve body 117. The end of the second guide pipe 114 away from the valve body 117 is installed in the middle of the middle of the middle chamber 125 near the valve body 117.

[0064] Furthermore, in specific implementation, when the temperature of the medicine box 102 and its surroundings decreases, the refrigerant inside the cooling pipe 122 and the middle compartment 125 tends to stabilize. Under normal conditions, the refrigerant will remain inside the middle compartment 125 and the cooling pipe 122 to continuously dissipate heat. When the temperature conducted from the medicine box 102 reaches the boiling point of the refrigerant, the refrigerant will quickly absorb heat and evaporate into a gaseous state. At this time, the pressure inside the cooling pipe 122 and the middle compartment 125 increases.

[0065] Among them, each of the conduits 114 near the valve body 117 is equipped with a wheel chamber 116, and each of the wheel chambers 116 is equipped with an impeller 128. The impeller 128 is installed on the outer periphery of the rotating pipe 135. The rotating pipe 135 is rotatably connected to the conduit 114. Each of the rotating pipes 135 is fixedly connected to a guide vane 127, which is rotatably connected to the inside of the conduit 114. Each of the wheel chambers 116 is fixedly connected to a connecting hose 136, and the other end of the connecting hose 136 is fixedly connected to the top of the refrigeration pipe 122. Each of the wheel chambers 116 is fixedly connected to a connecting hose 124, and the other end of the connecting hose 124 is fixedly connected to the bottom of the refrigeration pipe 122. Each of the connecting hose 124 and the connecting hose 136 near the refrigeration pipe 122 is equipped with a one-way valve.

[0066] Furthermore, in specific implementation, when the temperature of the ointment is too high, causing the refrigerant inside the refrigeration pipe 122 and the middle compartment 125 to sublimate too quickly, resulting in increased pressure inside the refrigeration pipe 122, some gas will enter the wheel compartment 116 through the connecting hose 136. This will drive the impeller 128 inside the wheel compartment 116 to rotate. The impeller 128 can drive the rotating pipe 135 and the guide vane 127 fixed to the rotating pipe 135 to rotate. The rotation of the guide vane 127 can accelerate the speed at which the refrigerant enters the middle compartment 125, realizing rapid replenishment of the refrigerant inside the middle compartment 125. This is beneficial for coping with the high-temperature environment of the ointment storage cabinet 1, thereby enabling continuous and uninterrupted cooling of the medicine box 102 and the ointment inside it.

[0067] Among them, a portion of the conduit 109 near the connecting pipe 108 is rotatably connected to a rotating pipe 134, a fan 111 is fixedly connected to the outer periphery of the rotating pipe 134, an impeller 121 is fixedly connected inside the rotating pipe 134, the fan 111 is located between the connecting pipe 108 and the upright frame 107, and the upright frame 107 has evenly distributed openings 110 in the middle, and the openings 110 correspond to the plate frame 104.

[0068] Furthermore, in specific implementation, the gas entering the wheel compartment 116 will be discharged back to the other end of the refrigeration pipe 122 through the connecting hose 124, and most of the gas inside the refrigeration pipe 122 will be collected directly into the connecting pipe 108 through the conduit 109.

[0069] Among them, heat-conducting columns 130 are movably connected inside the sleeve 132, and a top plate 115 is fixedly connected to the top of the heat-conducting column 130. The top plate 115 is located at the bottom of the medicine box 102. The bottom of the top plate 115 is fixedly connected to evenly distributed inclined guide plates 133. The inclined guide plates 133 are all set in an inclined state. The bottom of the heat-conducting column 130 is fixedly connected to the fan blade 126. The fan blade 126 is located at the lower part of the plate frame 104. Springs 131 are provided on the outer periphery of the heat-conducting column 130. The springs 131 are all located between the top plate 115 and the middle compartment 125.

[0070] Furthermore, in practical implementation, the pressure of the flowing gas impacts the impeller 121, thereby driving the rotating pipe 134 and the fan 111 to rotate. The rotation of the fan 111 disturbs the air inside the cabinet 101, forming an airflow, which further dissipates heat from the medicine box 102 and distributes the cooler air from the cooling pipe 122 and the top plate 115 to the remaining space inside the cabinet 101, resulting in higher heat dissipation efficiency. This helps to deal with heat accumulation and facilitates practical use. At the same time, when the fan 111 starts to rotate rapidly... The airflow generated by the fan 111 passes through the opening 110 and impacts the inclined guide plate 133 at the bottom of the top plate 115, thereby causing the top plate 115 to rotate. The rotation of the top plate 115 can drive the heat-conducting column 130 and the fan blade 126 at the bottom of the heat-conducting column 130 to rotate. The rotation of the fan blade 126 can drive the surrounding air to flow. At the same time, the fan blade 126 can also distribute the cooler air at the cooling pipe 122, and can realize the rapid cooling and molding of the lower medicine box 102 and the ointment inside, which is beneficial to practical use.

[0071] The cabinet 101 has a bottom compartment 105 at its bottom. A pump unit 112 is installed on one side of the bottom compartment 105, and a condenser pipe 119 is installed on the other side of the bottom compartment 105. A cooling plate 120 is installed at the bottom of the condenser pipe 119. The cooling plate 120 is installed on one side of the bottom of the bottom compartment 105. The pump unit 112 consists of a storage tank and a booster pump. The storage tank is connected to the condenser pipe 119, and the output end of the booster pump is connected to the discharge pipe 113. The racks 104 are all provided with evenly distributed ventilation openings. Temperature sensors are installed on the front top of the racks 104. The temperature sensors are electrically connected to the cooling plate 120 and the pump unit 112. When the temperature is high (generally 10°C above the boiling point of the refrigerant), the cooling plate 120 and the pump unit 112 increase their working power, accelerate the circulation speed, and improve the working effect. When the temperature is lower than the preset value (below the boiling point of the refrigerant), the cooling plate 120 and the pump unit 112 do not work.

[0072] Furthermore, in specific implementation, some gas will be collected through conduit 109 into the connecting pipe 108, and then the gaseous refrigerant can be condensed through condenser 119, so that the refrigerant can be recycled. The cooling plate 120 can increase the condensation effect and condensation speed of condenser 119, which facilitates the rapid recovery of refrigerant.

[0073] One of the intelligent drug management methods is characterized by:

[0074] S1. Power-on initialization and refrigerant pre-charge:

[0075] S1.1 When the power is turned on, the cabinet 101 will automatically perform a self-test, and the temperature sensor, pump group 112, cooling chip 120, and valve body 117 will enter the standby state.

[0076] S1.2, Pump unit 112 starts, and the refrigerant in the storage tank of bottom silo 105 is transported to the middle silo 125 of each plate rack 104 through discharge pipe 113, riser pipe 118, valve body 117, and conduit 2 114. Then, it is evenly filled into the refrigeration pipe 122 through the through pipe 123 to complete the pre-charge of the refrigerant circuit.

[0077] S1.3 After pre-charging is completed, the controller enters standby mode. When the temperature is lower than the preset threshold, the pump group 112 and the cooling chip 120 stop operating.

[0078] S2. Temperature monitoring and intelligent start / stop control:

[0079] S2.1 Temperature sensors on the front of each shelf 104 collect the ambient temperature of the medicine box 102 and the cabinet 101 in real time.

[0080] S2.2 Temperature Judgment Rules:

[0081] ① Temperature 10°C higher than the boiling point of the refrigerant: This is considered a high temperature. Pump unit 112 and refrigeration element 120 operate at full power to accelerate the refrigerant circulation.

[0082] ② When the temperature is near the boiling point of the refrigerant: the refrigerant absorbs heat and evaporates, then enters a natural circulation to dissipate heat;

[0083] ③ When the temperature is lower than the preset safety value: Pump unit 112 and cooling plate 120 stop, and the refrigerant remains stationary for insulation;

[0084] S2.3 Temperature data is fed back in real time, and the controller automatically adjusts the cooling power to maintain a constant temperature environment for ointment storage;

[0085] S3, Core Cooling and Heat Dissipation Management:

[0086] S3.1 Direct heat conduction cooling: The bottom of the medicine box 102 is in close contact with the top plate 115. Heat is conducted to the refrigerant in the middle compartment 125 through the heat conduction column 130, the sleeve 132, and the heat conduction plate 129. The refrigerant absorbs heat quickly, realizing direct cooling of the medicine box 102.

[0087] S3.2 Ambient cooling: The cooling pipes 122 are distributed on the outside of the plate frame 104 to continuously cool the air around the medicine box 102, forming an ambient cooling environment to accelerate the cooling and molding of the ointment.

[0088] S3.3 Refrigerant Circulation and Regeneration: The refrigerant absorbs heat and evaporates into a gaseous state. The pressure inside the middle compartment 125 and the refrigeration pipe 122 increases. The gaseous refrigerant is collected through the conduit 109 to the connecting pipe 108 and enters the condenser pipe 119. With the assistance of the refrigeration plate 120, it is condensed into a liquid state and flows back to the storage tank of the pump group 112 to achieve recycling.

[0089] S4. High-Temperature Emergency and Adaptive Flow Management:

[0090] S4.1 When the temperature of the ointment is too high, causing the refrigerant to sublimate rapidly and the pressure of the refrigeration pipe 122 to increase sharply: some gaseous refrigerant enters the wheel chamber 116 through the connecting hose 136, which drives the impeller 128 to rotate, and drives the rotating pipe 135 and the guide vane 127 to rotate, accelerating the speed at which the refrigerant flows into the middle chamber 125 and quickly replenishing the refrigerant to cope with the high temperature.

[0091] S4.2 The gas in the wheel compartment 116 is discharged back to the refrigeration pipe 122 through the connecting hose 124 to complete a local small circulation and ensure stable pressure;

[0092] S5, Airflow-linked heat dissipation management:

[0093] S5.1 When the gaseous refrigerant flows through the duct 109, it impacts the impeller 121, causing the rotating pipe 134 and the fan 111 to rotate, disturbing the air inside the cabinet 101, and spreading the cold air at the cooling pipe 122 and the top plate 115 to the whole cabinet, thereby improving the overall heat dissipation efficiency.

[0094] S5.2 The airflow from the fan 111 passes through the opening 110 of the stand 107 and impacts the inclined guide plate 133 at the bottom of the top plate 115, causing the top plate 115, the heat conduction column 130 and the bottom fan blade 126 to rotate, further enhancing the airflow at the lower medicine box 102 and accelerating heat dissipation.

[0095] S6. Routine Maintenance and Management:

[0096] S6.1 Regularly check the refrigerant level and replenish it to the standard level if it is insufficient;

[0097] S6.2 Clean the dust from the ventilation openings of the plate frame 104 and the surface of the cooling pipe 122 to ensure heat conduction and ventilation efficiency;

[0098] S6.3 Verify the accuracy of the temperature sensor to ensure accurate temperature control; check the operating status of pump unit 112, cooling element 120, and valve body 117, and replace faulty parts in a timely manner.

[0099] S6.4 Keep cabinet door 103 closed to reduce cold loss and lower controller energy consumption;

[0100] S7, Power Off Management:

[0101] S7.1 First, remove the medicine from cabinet 101 and close cabinet door 103;

[0102] S7.2 Press the power off button, and the pump unit 112 and the cooling coil 120 will stop running, and the refrigerant will flow back to the storage tank;

[0103] S7.3 After the controller completes refrigerant recovery, disconnect the main power supply.

[0104] Working principle:

[0105] In practical use, the medicine box 102 inside the medicine storage cabinet 1 stores the prepared medicine. When the medicine is placed in the medicine storage cabinet 1, the dissipated heat will gradually accumulate in the windless environment, causing the interior of the cabinet 101 to reach a high temperature, affecting the cooling and solidification of the medicine and its storage. In actual use, the pump unit 112 inside the bottom compartment 105 can input refrigerant into the riser pipe 118 through the discharge pipe 113. The valve body 117 on the riser pipe 118 can input the refrigerant into each conduit 114. The refrigerant is introduced into the middle compartment 125 through the conduit 114, and further introduced into the refrigeration pipe 122 through the connecting pipe 123. The medicine box 102 is tightly attached to the top. Plate 115 conducts heat from the medicine box 102 to the heat-conducting plate 129 through the heat-conducting column 130 and sleeve 132, thereby heating the refrigerant. The refrigerant inside the cooling pipe 122 and the middle compartment 125 quickly absorbs heat, achieving automatic cooling. It also absorbs heat from the heat-conducting column 130 and top plate 115, directly dissipating heat from the top plate 115 to the medicine box 102. The cooling pipe 122 cools the surrounding environment of the medicine box 102, allowing the operating temperature of the medicine box 102 to drop to a suitable threshold more quickly. Once the temperature of the medicine box 102 and its surroundings decreases, the refrigerant inside the cooling pipe 122 and the middle compartment 125 stabilizes, and under normal conditions, the refrigerant remains in the middle compartment 125. The refrigerant continuously dissipates heat within the cooling pipe 122. When the temperature conducted from the medicine box 102 reaches the boiling point of the refrigerant, the refrigerant rapidly absorbs heat and evaporates into a gaseous state. At this time, the pressure inside the cooling pipe 122 and the middle compartment 125 increases, and some of the gas flows through the first conduit 109 to the connecting pipe 108. Then, the gaseous refrigerant is condensed by the condenser pipe 119, allowing for refrigerant recycling. The cooling element 120 increases the condensation effect and speed of the condenser pipe 119, facilitating rapid refrigerant recovery. When the ointment temperature is too high, causing the refrigerant inside the cooling pipe 122 and the middle compartment 125 to sublimate too quickly, resulting in increased pressure inside the cooling pipe 122, some of the gas enters the wheel compartment 1 through the second connecting hose 136. Inside compartment 116, the impeller 128 inside the wheel compartment 116 rotates. The impeller 128 drives the rotating pipe 135 and the guide vane 127 fixed to it to rotate. The rotation of the guide vane 127 accelerates the entry of refrigerant into the middle compartment 125, rapidly replenishing the refrigerant inside. This helps cope with the high-temperature environment of the ointment storage cabinet 1, enabling continuous and uninterrupted cooling of the medicine box 102 and its contents. The gas entering the wheel compartment 116 is discharged back to the other end of the refrigeration pipe 122 through the connecting hose 124. Most of the gas inside the refrigeration pipe 122 is directly collected into the connecting pipe 108 through the conduit 109. During this process...The pressure of the flowing gas impacts the impeller 121, causing the rotating pipe 134 and fan 111 to rotate. The rotation of fan 111 disturbs the air inside cabinet 101, creating airflow, which further dissipates heat from the medicine box 102 and distributes cooler air from the cooling pipe 122 and top plate 115 to the remaining space inside cabinet 101, resulting in higher heat dissipation efficiency and better handling of heat buildup for convenient use. Simultaneously, when fan 111 starts rotating rapidly... The generated airflow passes through opening 110 and impacts the inclined guide plate 133 at the bottom of top plate 115, causing top plate 115 to rotate. This rotation of top plate 115 drives the heat-conducting column 130 and the fan blades 126 at its bottom to rotate. The rotation of fan blades 126 causes the surrounding air to flow, and also disperses the cooler air at cooling pipe 122, enabling rapid cooling and molding of the lower medicine box 102 and its internal ointment, which is beneficial for practical use.
