[0016] In summary, the present application includes at least one of the following beneficial technical effects: 1. Since the second temperature sensor measures the temperature of the water in the first tube, and the third temperature sensor measures the temperature of the water in the second tube, the temperature of the water in the first tube is room temperature water at first. After heat exchange with the body, the temperature is much higher than the temperature in the second tube, while the temperature in the second tube is much lower than the temperature in the body due to the rapid cooling of the ammonium nitrate particles and water after the reaction. As the fan blows air into the body, the air flow and heat exchange in the body are enhanced. At this time, the temperature in the second tube gradually approaches the temperature in the body, but it is still lower than the temperature in the first tube. Therefore, the water in the first tube can be put back into the water tank through the third tube and the return pipe, and the first solenoid valve is kept closed to avoid affecting the water in the second tube. When the water in the first tube is drained, the water in the second tube can be pushed into the first tube through the pushing component to maximize the use of water for ammonium nitrate refrigeration; 2. When it is necessary to open only the first pipe, the circulation solenoid valve on the first pipe is opened and the first solenoid valve is closed to prevent the circulating water from entering the second pipe. At this time, water circulates in the first pipe to achieve the water cooling effect. When it is necessary to open the cooling effect in the second pipe, the circulation solenoid valve on the first pipe and the first solenoid valve need to be closed. The water in the water tank is pumped into the second pipe by the circulation water pump, and the cooling is performed by the adjustment component. When the cooling is completed, the first solenoid valve and the circulation solenoid valve on the return pipe are still opened. At this time, the water enters the third pipe from the second pipe and then flows into the water tank, completing the water circulation work; 3. When the ammonium nitrate particles in the receiving pipe are consumed, the control panel needs to be pulled to the initial position. The traction motor is controlled to drive the traction roller to rotate. The traction roller pulls the traction rope upward and winds it. The control panel is pulled to the top of the traction box to facilitate the subsequent feeding into the receiving pipe. While the control panel monitors the position of the ammonium nitrate particles in the receiving pipe, the traction rope is always in a relaxed state to prevent the traction rope from affecting the position of the control panel. The control panel can drive the external infrared receiver to move together, thereby ensuring that the position of the infrared receiver is the position of the ammonium nitrate particles. When the infrared receiver moves to receive the signal from the infrared transmitter, it proves that the ammonium nitrate in the receiving pipe has been consumed and the storage tank needs to be replaced.

[0019] The following is combined with Figure 1-5 This application is described in further detail.

[0020] The present application embodiment discloses a multifunctional audio and video integrated conference machine. Figure 1-Figure 5A multifunctional audio and video integrated conference machine includes a body 1, a first temperature sensor 2 and a blower mechanism 3 arranged in the body 1; it also includes an audio and video acquisition module, the audio and video acquisition module adopts the GM8128 chip, combined with its audio AD interface, to provide a CVBS interface and a YPbPr interface; a signal transmission module, the signal transmission module includes a wireless transmission module and a USB port; an audio and video playback module, the audio and video playback module includes an IPS screen and a speaker; a video processing module, the audio and video decoding module includes an ADV7181C high-definition video processing chip, the ADV7181C high-definition video processing chip can process the video signal transmitted by the audio and video acquisition module, realize multi-channel merging, transmission and realize audio and video decompression, and control the operation of the audio and video playback module.

[0021] Reference Figure 1-Figure 3 The first temperature sensor 2 is used to monitor the temperature inside the body 1. For example, a maximum temperature is set for the specific body. If the set temperature is exceeded, the temperature needs to be quickly cooled to avoid damaging the components in the body 1. The hair dryer 3 includes a fan, and the shell of the body 1 is also provided with corresponding heat dissipation holes for cooling the body 1. Of course, in this embodiment, the first temperature sensor 2 can be controlled by the PLC controller to connect a buzzer or a display light, as long as it can serve to prompt the staff.

[0022] The machine body 1 is also provided with a heat dissipation device for cooperating with the blowing structure to accelerate the temperature reduction in the machine body 1. The heat dissipation device includes a water cooling mechanism for cooling by water circulation and a refrigeration mechanism for cooling; the water cooling mechanism includes a first tube 4, a second temperature sensor 5 arranged in the first tube 4, and a circulation component for realizing water circulation in the first tube 4. The first tube 4 is located in the wind direction blown by the fan. The first tube 4 is arranged in the machine body 1 and is vertically arranged. The first tube 4 is located in front of the fan. When the temperature in the machine body 1 exceeds the set temperature, it is necessary to pass circulating water into the first tube 4 through the circulation component. Since the circulating water is at room temperature, the machine body 1 can be quickly cooled down under the action of the fan. Due to the environmental problems of the placement of the all-in-one machine, the water in the circulation component is also limited. With the water circulation cooling and the water in the first tube 4 exchanging heat with the machine body 1, the water temperature in the circulation component gradually increases. The second temperature sensor 5 measures the temperature of the water in the first tube 4. If the water temperature in the circulation component cannot quickly cool down the machine body 1, the refrigeration mechanism needs to start working.

[0023] Reference Figure 1-Figure 3The refrigeration mechanism includes a second tube 6, a third tube 7, a first solenoid valve 8, a third temperature sensor 9, a pushing component for pushing the water in the second tube 6, and a regulating component for quickly reducing the temperature of the water in the second tube 6. The third tube 7 is set as a curved tube, and the two ends of the third tube 7 are respectively connected to the tail ends of the second tube 6 and the first tube 4. The first solenoid valve 8 is set at the connection position of the second tube 6 and the third tube 7. Therefore, the first tube 4, the second tube 6 and the third tube 7 form a U-shape, and the second tube 6 and the first tube 4 are arranged in a vertical direction along the blowing direction of the fan, and the first tube 4 is located closer to the fan. Therefore, even if the temperature of the first tube 4 is higher than that of the second tube 6, at this time, under the action of the second tube 6, the air coming out of the position of the first tube 4 can be cooled, so that the air with a lower temperature can be blown into the body 1, which greatly accelerates the cooling speed of the body 1.

[0024] The circulation component includes a water tank 10 arranged in the external environment, a circulating water pump 11 arranged in the water tank 10, a main pipe 12, a first water pipe 13, a second water pipe 14, three circulating solenoid valves 15 and a return pipe 16. The water tank 10 is used for external connection. Due to the existence of the regulating component, the water in the water tank 10 does not need to be much. The output end of the circulating water pump 11 is connected to the main pipe 12, the first water pipe 13 and the second water pipe 14 are respectively connected to the two ends of the main pipe 12, the three circulating solenoid valves 15 are respectively arranged on the first water pipe 13, the second water pipe 14 and the return pipe 16, the return pipe 16 is connected to the bottom end of the third pipe 7, and the other end of the return pipe 16 is connected to the water tank 10. The water tank 10 is located lower than the bottom end of the first water pipe 13, and the side wall of the second pipe 6 is provided with The third temperature sensor 9 is arranged in the mounting hole; when it is necessary to open only the first tube 4, the circulation solenoid valve 15 on the first tube 4 is opened and the first solenoid valve 8 is closed to prevent the circulating water from entering the second tube 6. At this time, water circulates in the first tube 4 to achieve the water cooling effect, and when it is necessary to open the cooling effect in the second tube 6, it is necessary to close the circulation solenoid valve 15 on the first tube 4 and the first solenoid valve 8, and pump the water in the water tank 10 into the second tube 6 through the circulation water pump 11, and refrigeration is performed through the adjustment component. When the refrigeration is completed, the first solenoid valve 8 and the circulation solenoid valve 15 on the return pipe 16 are still opened. At this time, the water enters the third tube 7 from the second tube 6 and then flows into the water tank 10 to complete the water circulation work.

[0025] Reference Figure 1-Figure 4The regulating assembly includes a storage tank 17 detachably arranged on the body 1, a cover 18, a material receiving pipe 19, a regulating solenoid valve 20 arranged at the bottom of the material receiving pipe 19, an opening part for opening the cover 18, a connecting part for connecting the material receiving pipe 19 and the second pipe 6, and a monitoring part for monitoring the material height in the material receiving pipe 19. Ammonium nitrate particles are sealed in the storage tank 17. Ammonium nitrate is a commonly used chemical refrigerant. When it is dissolved in water, it absorbs a large amount of heat to reduce the temperature of the solution. Therefore, in this embodiment, the first pipe 4 and the second pipe 6 need to be made of materials with good thermal conductivity. In order to facilitate heat transfer between sodium nitrate and air after the temperature is reduced, the opening of the storage tank 17 is sealed by a cover 18, the material receiving pipe 19 is fixed in the body 1, and is connected to the top of the second tube 6 through a connecting portion, and an insertion port 21 is provided on the top of the body 1, and the tank mouth of the storage tank 17 is adapted to the insertion port 21, and the insertion port 21 is provided at a specific top, so that the ammonium nitrate can be sealed and carried during daily use. When it is necessary to start cooling, at this time, only the tank mouth of the storage tank 17 needs to be inserted into the insertion port 21, and the installation of the storage tank 17 is completed at this time, and the tank body of the storage tank 17 is located outside the body 1.

[0026] The opening part includes a protrusion 22, an electromagnet 23 and an opening rod 24. The protrusion 22 is fixedly connected to the side wall of the cover 18. The mouth of the storage tank 17 is provided with a slide 25. The slide 25 is along the length direction of the mouth of the storage tank 17. Both ends of the slide 25 are opened. The side wall of the slide 25 is provided with an arc groove 26. The protrusion 22 is slidably adapted with the arc groove 26. The protrusion 22 rotates from the slide 25 to the arc groove 26. The slide 25 is detachably provided with a rubber strip 27 at a position close to the mouth of the storage tank 17. The opening rod 24 is fixed at the opening of the receiving pipe 19. The electromagnet 23 is provided at the opening of the storage tank 17. 23 is fixed on the end of the opening tube, and the cover 18 is provided with an opening 28. The opening 28 is adapted to the cross-section of the opening rod 24 and both are set to be rectangular. The electromagnet 23 adsorbs the cover 18. Since the two ends of the slide groove 25 are set to penetrate, when the protrusion 22 rotates into the arc groove 26, although the cover 18 and the tank mouth of the storage tank 17 are clamped, in order to prevent the ammonium nitrate particles from leaking out of the slide groove 25, a rubber strip 27 is inserted into the slide groove 25 toward the tank mouth of the storage tank 17. After the rubber strip 27 is inserted into the slide groove 25, it is squeezed and deformed to seal the slide groove 25.

[0027] When the mouth of the storage tank 17 is inserted into the opening of the insertion port 21, the opening rod 24 is inserted into the opening port 28, and the electromagnet 23 is energized. The electromagnet 23 adsorbs the cover 18 to prevent the cover 18 from falling during the movement toward the storage tank 17. Since the cross-sections of the opening rod 24 and the opening port 28 are both set to be square, the storage tank 17 can be controlled to rotate at this time, and the storage tank 17 and the cover 18 move relative to each other. The protrusion 22 rotates from the arc groove 26 to the slide groove 25. At this time, the storage tank 17 continues to be inserted into the insertion port 21, and the opening rod 24 drives the cover 18 to move toward the storage tank 17. Since the ammonium nitrate particles in the storage tank 17 are not full, there is enough space for the opening rod 24 to move. When the cover 18 moves into the tank body of the storage tank 17, the ammonium nitrate particles roll from the storage tank 17 toward the material receiving pipe 19 to complete the material receiving work.

[0028] Reference Figure 1-Figure 4 The connection part includes a connection box 29, a spacer 30 movably arranged in the connection box 29, and a winding group for winding the spacer 30. The connection box 29 is used to connect the material receiving pipe 19 and the top of the second pipe 6. The position where the second water pipe 14 is connected to the second pipe 6 is located below the connection box 29. The spacer 30 is used to separate the water in the second pipe 6 and the ammonium nitrate particles in the material receiving pipe 19. The area of ​​the spacer 30 is larger than the cross-sectional area of ​​the connection box 29. The role of the spacer 30 in this embodiment is to separate the water and the ammonium nitrate particles to prevent the material receiving pipe 19 from being contaminated by water splashing. ammonium nitrate particles, so the isolation member 30 needs to be made of a material with good water-proof performance to ensure the isolation of water; the winding group includes two winding ropes 31, two winding rollers 32 and two winding motors 33, the two ends of the isolation member 30 are respectively fixedly connected to the two winding ropes 31, the other ends of the two winding ropes 31 are respectively fixedly connected to the peripheral walls of the two winding rollers 32, the two opposite inner walls of the isolation box are each provided with a winding cavity, and the winding cavity is provided with a through opening, the winding roller 32 is rotatably arranged in the winding cavity, and the winding motor 33 is installed in the winding cavity to control the rotation of the winding roller 32.

[0029] In the initial state, the isolation member 30 separates the receiving pipe 19 from the second pipe 6, that is, the isolation member 30 is located in the connecting box 29, and the area of ​​the isolation member 30 is larger than the area in the isolation box, thereby achieving the effect of completely isolating the water. When it is necessary to add ammonium nitrate particles into the second pipe 6, it is necessary to control the winding motor 33 to start rotating the winding roller 32. Under the action of the two winding motors 33 rotating at the same frequency and in the same direction, the winding rope 31 is pulled out of the winding cavity, that is, there is only the winding rope 31 in the connecting box 29. Therefore, the winding rope 31 will not affect the normal falling of the ammonium nitrate particles. The ammonium nitrate particles fall into the second pipe 6, thereby achieving a refrigeration effect, greatly accelerating the cooling efficiency in the body 1.

[0030] Since the second temperature sensor 5 measures the temperature of the water in the first tube 4, and the third temperature sensor 9 measures the temperature of the water in the second tube 6, the temperature of the water in the first tube 4 is room temperature water at the beginning. After the heat exchange with the body 1, the temperature is much higher than the temperature in the second tube 6, and the temperature in the second tube 6 is much lower than the temperature in the body 1 due to the rapid cooling of the ammonium nitrate particles after the reaction with water. As the fan blows air into the body 1, the air flow and heat exchange in the body 1 are enhanced, and the temperature in the second tube 6 gradually approaches the temperature in the body 1, but it is still lower than the temperature in the first tube 4. Therefore, the water in the first tube 4 can be returned to the water tank 10 through the third tube 7 and the return pipe 16, and the first solenoid valve 8 is kept closed to avoid affecting the water in the second tube 6. When the water in the first tube 4 is discharged, the water in the second tube 6 can be pushed into the first tube 4 by the pushing component to maximize the use of water for ammonium nitrate refrigeration.

[0031] Reference Figure 1-Figure 5 The pushing assembly includes a pushing plate 43, a shielding plate 44, a shielding box 45, a shielding motor 46 and a pushing member 47 for realizing the reciprocating motion of the pushing plate. The pushing plate is slidably adapted to the second pipe 6. A pushing port is provided on the pushing plate 43. The shielding plate 44 is rotatably provided on the pushing plate. The shielding box 45 is fixed on the pushing plate 43. The shielding motor 46 is installed in the shielding box 45 and its output end is fixedly connected to one end of the shielding plate 44. The shielding plate 44 rotates to a position to block the pushing port. When the pushing plate 43 needs to move downward, the pushing port needs to be controlled to be in a blocking position, and when the pushing plate 43 moves upward, the pushing port can be opened. The pushing member 47 uses an electric push rod in this embodiment; when it is necessary to direct the water in the second pipe 6 toward the first pipe 4, the first solenoid valve 8 is opened and the circulation solenoid valve 15 on the first water pipe 13 is closed, and the shielding motor 4 6 rotates the shielding plate 44 until the push port is blocked, at which time the push member 47 moves the push plate downward until it moves to the position of the first electromagnetic valve 8, that is, the water in the second tube 6 has been pushed to the third tube 7 and the second tube 6, and the water in the second tube 6 can still continue to be cooled; at this time, the first electromagnetic valve 8 needs to be closed, and the push port is opened, the push plate 43 is pulled upward to the initial position, the circulation electromagnetic valve 15 on the second water pipe 14 is opened, the water in the water tank 10 is pumped into the second tube 6, and the regulating electromagnetic valve 20 at the bottom of the borrowing pipe is opened, and the control winding rope 31 is located in the connecting box 29, and the ammonium nitrate particles fall into the second tube 6. At this time, the water temperature in the second tube 6 drops rapidly again. Therefore, the old ice water in the first tube 4 and the new ice water in the second tube 6 continue to cool the body 1, which can improve the utilization efficiency and accelerate the cooling of the body 1.

[0032] The monitoring unit includes an infrared transmitter 34, an infrared receiver 35, and a control group for achieving synchronization of the infrared transmitter 34 with the material height in the receiving tube 19. The infrared transmitter 34 is fixed in the machine body 1 and is directly opposite to the lowest end of the receiving tube 19. The infrared receiver 35 is slidably arranged on the outer wall of the receiving tube 19. When the infrared receiver 35 moves to receive the signal of the infrared transmitter 34, it proves that the ammonium nitrate in the receiving tube 19 has been consumed. Similarly, the infrared receiver 35 can also be controlled by a PLC controller and connected to a buzzer or a display light to warn the staff; the control group includes a control panel 36, two magnet blocks 37 and a partition 38. The weight of the control panel 36 is greater than that of the infrared receiver 35. The two magnet blocks 37 are respectively connected to the control panel 36 and the infrared receiver 35. The device 35 is fixedly connected, the side wall of the material receiving pipe 19 is provided with an adsorption port, the partition 38 is fixed in the adsorption port, the two magnet blocks 37 are respectively located on both sides of the partition 38 and adsorbed to each other, the area of ​​the control disk 36 is smaller than the inner diameter of the material receiving pipe 19, and in this embodiment, it is assumed that the control disk 36 is located at the top of the ammonium nitrate particles and is always in a horizontal state. The weight of the control disk 36 is set to be greater than the weight of the infrared receiver 35, mainly to ensure that the control disk 36 can drive the external infrared receiver 35 to move together, and then to ensure that the position of the infrared receiver 35 is the position of the ammonium nitrate particles. In this embodiment, the partition 38 is mainly to reduce its thickness and use a material with the least effect on the adsorption between the magnet blocks 37. Therefore, the two magnet blocks 37 are in a state of adhesion together during the whole process.

[0033] A traction group for traction of the control disk 36 is also provided in the receiving tube 19, and the traction group includes a traction box 39, a traction rope 40, a traction roller 41 and a traction motor 42. The traction box 39 is fixed at the top of the side wall of the receiving tube 19, and a traction hole is provided at the bottom of the traction box 39. The traction rope 40 passes through the traction hole and is fixedly connected to the control disk 36, and the other end of the traction rope 40 is fixedly connected to the traction roller 41. The traction motor 42 is installed in the traction box 39 and is used to control the rotation of the traction roller 41; when the ammonium nitrate particles in the receiving tube 19 are consumed, the control disk 36 needs to be pulled to the initial position at this time, and the traction roller 41 is driven to rotate by controlling the traction motor 42, and the traction roller 41 pulls the traction rope 40 upward and winds it, and the control disk 36 is pulled to the top of the traction box 39 for subsequent feeding into the receiving tube 19. In the process of the control disk 36 monitoring the position of the ammonium nitrate particles in the receiving tube 19, the traction rope 40 is always in a loose state to prevent the traction rope 40 from affecting the position of the control disk 36.

[0034] The implementation principle of a multifunctional audio and video integrated conference machine in the embodiment of the present application is: when it is necessary to open only the first tube 4, the circulation solenoid valve 15 on the first tube 4 is opened and the first solenoid valve 8 is closed to prevent the circulating water from entering the second tube 6. At this time, water circulates in the first tube 4 to achieve a water cooling effect. When it is necessary to open the cooling effect in the second tube 6, it is necessary to close the circulation solenoid valve 15 on the first tube 4 and the first solenoid valve 8. The water in the water tank 10 is pumped into the second tube 6 by the circulation water pump 11, and refrigeration is performed by adjusting the component. When the refrigeration is completed, the first solenoid valve 8 and the circulation solenoid valve 15 on the return pipe 16 are still opened. At this time, the water enters the third tube 7 from the second tube 6 and then flows into the water tank 10 to complete the water circulation work.

[0035] When the mouth of the storage tank 17 is inserted into the opening of the insertion port 21, the opening rod 24 is inserted into the opening port 28, and the electromagnet 23 is energized. The electromagnet 23 adsorbs the cover 18 to prevent the cover 18 from falling during the movement toward the storage tank 17. Since the cross-sections of the opening rod 24 and the opening port 28 are both set to be square, the storage tank 17 can be controlled to rotate at this time, and the storage tank 17 and the cover 18 move relative to each other. The protrusion 22 rotates from the arc groove 26 to the slide groove 25. At this time, the storage tank 17 continues to be inserted into the insertion port 21, and the opening rod 24 drives the cover 18 to move toward the storage tank 17. Since the ammonium nitrate particles in the storage tank 17 are not full, there is enough space for the opening rod 24 to move. When the cover 18 moves into the tank body of the storage tank 17, the ammonium nitrate particles roll down from the storage tank 17 toward the receiving pipe 19 to complete the receiving work; since the second temperature sensor 5 is connected to the first pipe 4 The temperature of the water in the first tube 4 is measured, and the third temperature sensor 9 measures the temperature of the water in the second tube 6. The temperature of the water in the first tube 4 is room temperature water at first. After heat exchange with the body 1, the temperature is much higher than the temperature in the second tube 6. The temperature in the second tube 6 is much lower than the temperature in the body 1 due to the rapid cooling of the ammonium nitrate particles after the reaction with water. As the fan blows air into the body 1, the air flow and heat exchange in the body 1 are enhanced. At this time, the temperature in the second tube 6 is gradually close to the temperature in the body 1, but it is still lower than the temperature in the first tube 4. Therefore, the water in the first tube 4 can be returned to the water tank 10 through the third tube 7 and the return pipe 16, and the first solenoid valve 8 is kept closed to avoid affecting the water in the second tube 6. When the water in the first tube 4 is discharged, the water in the second tube 6 can be pushed into the first tube 4 by the pushing component to maximize the use of water for ammonium nitrate refrigeration.

[0036] When the ammonium nitrate particles in the receiving pipe 19 are consumed, the control panel 36 needs to be pulled to the initial position, and the traction roller 41 is driven to rotate by controlling the traction motor 42. The traction roller 41 pulls the traction rope 40 upward and winds it, and the control panel 36 is pulled to the top of the traction box 39 to facilitate the subsequent feeding into the receiving pipe 19. During the process of the control panel 36 monitoring the position of the ammonium nitrate particles in the receiving pipe 19, the traction rope 40 is always in a relaxed state to prevent the traction rope 40 from affecting the position of the control panel 36. The control panel 36 can drive the external infrared receiver 35 to move together, thereby ensuring that the position of the infrared receiver 35 is the position of the ammonium nitrate particles. When the infrared receiver 35 moves to receive the signal from the infrared transmitter 34, it proves that the ammonium nitrate in the receiving pipe 19 has been consumed and the storage tank 17 needs to be replaced.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
