[0002] A circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions and close, carry, and interrupt current under abnormal circuit conditions within a specified time. It can protect power lines and motors, and can automatically disconnect the circuit in the event of a short circuit.
[0003] Patent publication number CN216773943U discloses a low-voltage switchgear for easy circuit breaker installation, including a cabinet, a circuit breaker, a busbar, and a support device. The support device includes a support column, a circuit breaker mounting plate, and two support beams. The two support beams are fixed to the left and right sides of the cabinet, respectively. The circuit breaker mounting plate and the support column are fixed between the two support beams, and the support column is fixed to the front end of the circuit breaker mounting plate. The circuit breaker is mounted on the circuit breaker mounting plate, and the busbar is connected to the circuit breaker. This patent shortens the length of the circuit breaker mounting plate, effectively avoiding the difficulty of threading screws and the problem of insufficient insulation distance.
[0004] However, the device still has shortcomings: when the temperature of the switch cabinet rises rapidly during long-term operation, it is difficult to take effective measures to cool it down. Over time, this can easily lead to aging of the circuit, shorten the service life of the circuit, and create a risk of short circuit. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a low-voltage switchgear that facilitates the installation of circuit breakers, thus solving the problems mentioned in the background section.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a low-voltage switchgear for easy installation of circuit breakers, comprising a main body, an internal meter assembly, an external disconnection assembly, and a temperature controller on top of the meter assembly. When a short circuit occurs in the internal meter assembly after prolonged use, the disconnection assembly automatically cuts off the circuit to prevent fire. The device also includes an anti-softening device, an anti-damage device, an anti-deposition device, and an anti-adhesion device. The anti-softening device is located on the left side inside the main body, the anti-damage device is located on the right side inside the main body, the anti-deposition device is located inside the anti-damage device, and the anti-adhesion device is located inside the anti-damage device. The device is positioned below the heat-absorbing device, which includes a cooling fan, a U-shaped telescopic rod, and a sliding plate. The left side of the cooling fan is located on the left side of the inner wall of the device body. A thermostat controls the cooling fan to start, and the cooling fan draws heat away from the inside of the device body. The right back of the U-shaped telescopic rod is fixedly installed on the front of the cooling fan shaft, and the cooling fan shaft drives the U-shaped telescopic rod to rotate. The left side of the sliding plate is slidably installed on the left side of the inner wall of the device body. When the U-shaped telescopic rod rotates, the sliding plate slides back and forth up and down due to the restriction of the sliding plate groove. The right side of the sliding plate has a groove, and the back of the telescopic end of the U-shaped telescopic rod is slidably installed inside the sliding plate groove. The sliding plate disturbs the gas inside the device body, accelerating the heat extraction speed.
[0007] According to the above technical solution, the cooling fan has a built-in drive motor, and the back side of the right side of the U-shaped telescopic rod is non-centeredly connected to the front side of the cooling fan shaft.
[0008] According to the above technical solution, the damage prevention device includes an electric slide rail, a carbon dioxide assembly, a fire sensor, and a spray gun. The electric slide rail is fixedly installed on the right side of the inner wall of the device body. The fire sensor controls the start of the electric slide rail. The carbon dioxide assembly is slidably installed inside the electric slide rail on both the upper and lower sides. The electric slide rail drives the carbon dioxide assembly to move left and right. The bottom of the fire sensor is fixedly installed at the center of the top of the carbon dioxide assembly. The right side of the spray gun is fixedly installed on the left side of the carbon dioxide assembly. The carbon dioxide assembly sprays carbon dioxide gas into the interior of the device body through the spray gun. The carbon dioxide assembly then expands the carbon dioxide spray range by sliding left and right, thereby improving the fire extinguishing effect.
[0009] According to the above technical solution, the damage prevention device further includes a round rod blade, a connecting column, a heating ring, and a filter plate. The right side of the round rod blade is rotatably installed inside the spray gun. The spray force of the spray gun causes the round rod blade to rotate, stirring the carbon dioxide gas. The back of the connecting column is fixedly installed on the front of the outer wall of the round rod blade. When the round rod blade rotates, it drives the connecting column to rotate. The back of the inner wall of the heating ring is fixedly installed on the front of the connecting column, and the outer wall of the heating ring contacts the inner wall of the spray gun. The connecting column drives the heating ring to rotate, increasing the gas activity by heating the carbon dioxide gas. The outer wall of the filter plate is fixedly installed on the left side of the inner wall of the spray gun, and the right side of the filter plate contacts the left side of the round rod blade. The filter plate shields external gelatinous dirt during a fire, preventing external dirt from entering the carbon dioxide assembly through the spray gun and causing pollution.
[0010] According to the above technical solution, the anti-deposition device includes a lead screw rotating plate, a ring, and a reset plate. The lead screw rotating plate is installed through and fixedly mounted on the right side of the round rod cutter plate. When the round rod cutter plate rotates, it drives the lead screw rotating plate to rotate. The ring slides inside and is sleeved on the outer wall surface of the lead screw rotating plate. The clockwise rotation force of the lead screw rotating plate is limited by the spiral groove on the ring, causing the ring to slide to the right along the surface of the lead screw rotating plate. The reset plate is fixedly installed between the left side of the inner wall of the carbon dioxide assembly and the left side of the ring. When the reset plate elastically recovers, it pulls the ring to reset. Similarly, when the ring resets, it causes the lead screw rotating plate to rotate counterclockwise. The reciprocating rotation of the lead screw rotating plate agitates the carbon dioxide inside the carbon dioxide assembly.
[0011] According to the above technical solution, the anti-deposition device further includes a vertical plate, a rotating wheel, a brush rod, and a pulsating plate. The top of the vertical plate is fixedly installed at the bottom of the outer wall of the ring, and the ring drives the vertical plate to move left and right. The right side of the rotating wheel is rotatably installed on the left side of the vertical plate, and the outer wall of the rotating wheel contacts the bottom of the inner wall of the carbon dioxide assembly. The vertical plate drives the rotating wheel to move synchronously, and the rotating wheel starts to rotate due to the friction generated by contacting the bottom of the inner wall of the carbon dioxide assembly. The right side of the brush rod is fixedly installed on the left side of the rotating wheel, and the rotating wheel drives the brush rod to rotate. The brush rod rotates and disturbs the carbon dioxide at the bottom of the carbon dioxide assembly. The back of the pulsating plate is fixedly installed inside the brush rod, and the brush rod drives the pulsating plate to rotate, which to a certain extent increases the contact area between the brush rod and the carbon dioxide assembly.
[0012] According to the above technical solution, the anti-adhesion device includes a cylinder, a thin film, and a diverter ball. The left side of the cylinder is fixedly installed at the center of the right side of the cooling fan shaft, and an arc-shaped groove is opened on the outer wall of the cylinder. The cooling fan shaft drives the cylinder to rotate. The back side of the thin film is fixedly installed on the front side of the outer wall of the cylinder. When the cylinder rotates, it drives the thin film and the diverter ball to rotate. When the thin film rotates, it blocks the dirt carried by the cooling fan when it is drawing air. The left side of the diverter ball is fixedly installed on the right side of the cylinder. When the diverter ball rotates, the gas drawn by the cooling fan is diverted and discharged due to the restriction of the arc surface.
[0013] According to the above technical solution, the anti-adhesion device further includes a vertical rod, a wave plate, a swing plate, and a spring. The top of the vertical rod is slidably installed inside the cylindrical arc groove. When the cylinder rotates, the arc groove restricts the vertical rod, allowing it to move left and right. The bottom of the wave plate is slidably connected to the bottom of the inner wall of the device body, and the top arc surface of the wave plate is fixedly installed at the bottom of the vertical rod. The vertical rod drives the wave plate to move synchronously. The wave plate disturbs the heat at the bottom of the device body by its own wave arc surface, preventing heat from accumulating. The bottom of the swing plate is hinged to the right side of the wave plate arc surface. The wave plate drives the swing plate to move synchronously. The spring is fixedly installed between the right side of the swing plate and the wave plate arc surface. The swing plate is elastically reset by the spring, further expanding the contact range between the wave plate and the heat.
[0014] This invention provides a low-voltage switchgear that facilitates the installation of circuit breakers. It offers the following advantages:
[0015] (1) By setting up an anti-softening device, when a short circuit occurs in the internal meter component of the device body after long-term use, the cutting component automatically cuts off the circuit to prevent the circuit from catching fire; by setting up a cooling fan, the temperature controller controls the cooling fan to start, and the cooling fan draws away the heat inside the device body; by cooperating with the U-shaped telescopic rod and the sliding plate, when the U-shaped telescopic rod rotates, it is restricted by the sliding plate groove, so that the sliding plate slides up and down, disturbing the gas inside the device body, accelerating the heat dissipation speed, preventing the device body from running at high temperature for a long time, which would cause the internal circuit sheath to soften, shorten the service life of the circuit sheath in the long run, and avoid exposing the circuit and increasing the risk of short circuit.
[0016] (2) This invention, through the setting of the anti-damage device, uses an electric slide rail, carbon dioxide assembly, fire sensor and spray gun to spray carbon dioxide gas into the main body of the device through the spray gun. The carbon dioxide assembly expands the carbon dioxide spray range by sliding left and right, improving the fire extinguishing effect, shortening the fire burning time and reducing economic losses. Through the cooperation of the round rod blade, connecting column, heating ring and filter plate, the spray gun spray force causes the round rod blade to rotate, and the round rod blade stirs the carbon dioxide gas, promoting the uniformity of carbon dioxide gas spray. The round rod blade drives the connecting column to rotate, and the connecting column drives the heating ring to rotate. The heating ring rotates and heats the carbon dioxide gas, ensuring heating uniformity, while increasing the gas activity and improving the fire extinguishing effect. It also makes the filter plate shield the external gelatinous dirt when a fire occurs, preventing external dirt from entering the carbon dioxide assembly through the spray gun and causing pollution. The round rod blade rotates and scrapes the surface of the filter plate to prevent the filter plate from being blocked and preventing the carbon dioxide gas from being sprayed out.
[0017] (3) The present invention, through the setting of the anti-deposition device, through the cooperation of the round rod blade, the lead screw rotating plate, the ring and the reset plate, makes the ring slide to the right when the lead screw rotating plate rotates clockwise. The ring pulls the reset plate to deform synchronously. Then, when the reset plate recovers elastically, it pulls the ring to reset. The lead screw rotating plate rotates back and forth to stir the carbon dioxide inside the carbon dioxide assembly, preventing the carbon dioxide from accumulating due to long-term static storage and promoting the uniform distribution of carbon dioxide. Through the cooperation of the vertical plate, the rotating wheel, the brush rod and the agitator, the rotating wheel drives the brush rod to rotate. The brush rod rotates and disturbs the carbon dioxide at the bottom of the carbon dioxide assembly, accelerating the mixing speed of the upper and lower parts of the carbon dioxide and preventing the carbon dioxide gas from depositing. It also makes the brush rod drive the agitator to rotate. During the deformation and recovery process of the agitator, the contact area between the brush rod and the carbon dioxide assembly is expanded to a certain extent, thereby further disturbing the carbon dioxide gas at the bottom of the carbon dioxide assembly.
[0018] (4) The present invention, through the setting of the anti-adhesion device, through the cooperation of the cooling fan, cylinder, thin film and diverting ball, makes the thin film and diverting ball rotate when the cylinder rotates. The thin film blocks the dirt carried by the cooling fan when it is drawing air, and prevents the dirt from adhering to the cooling fan blades. At the same time, the diverting ball, through the arc surface, avoids the gas from impacting the center and increasing the temperature of the cooling fan, which would cause the cooling fan to reduce the frequency, thus ensuring that the cooling fan can operate efficiently for a long time. Through the cooperation of the vertical rod, wave plate, swing plate and spring, the vertical rod drives the wave plate to move left and right. The wave plate disturbs the heat at the bottom of the device body by its own wave arc surface, which surges upward, prevents heat from accumulating, and accelerates the heat dissipation efficiency inside the device body. It also makes the wave plate drive the swing plate to move synchronously. The swing plate is elastically reset by the spring, and this process is repeated to further expand the contact range between the wave plate and the heat, thereby further improving the heat agitation effect of the wave plate.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0028] Please see Figure 1-5 One embodiment of the present invention is: a low-voltage switchgear for easy installation of circuit breakers, comprising a device body 1, an electricity meter assembly 2 disposed inside the device body 1, a cut-off assembly 3 disposed around the electricity meter assembly 2, a temperature controller 31 disposed on the top of the electricity meter assembly 2, and further comprising an anti-softening device 4 and an anti-damage device 5. The anti-softening device 4 is disposed on the left side inside the device body 1, and the anti-damage device 5 is disposed on the right side inside the device body 1. The anti-softening device 4 comprises a cooling fan 41, a U-shaped telescopic rod 42, and a sliding plate 43. The left side of the cooling fan 41 is disposed on the left side of the inner wall of the device body 1, and the right back side of the U-shaped telescopic rod 42 is fixedly installed at the edge of the rotating shaft of the cooling fan 41. The sliding plate 43... The sliding plate 43 is slidably installed on the left side of the inner wall of the main body 1. A groove is opened on the right side of the sliding plate 43, and the back of the telescopic end of the U-shaped telescopic rod 42 is slidably installed inside the groove of the sliding plate 43. When the meter component 2 inside the main body 1 experiences a short circuit after prolonged use, the cut-off component 3 automatically cuts off the circuit to prevent the circuit from catching fire. The thermostat 31 controls the cooling fan 41 to start. The cooling fan 41 draws away the heat inside the main body 1. The shaft of the cooling fan 41 drives the U-shaped telescopic rod 42 to rotate. When the U-shaped telescopic rod 42 rotates, it is restricted by the groove of the sliding plate 43, causing the sliding plate 43 to slide up and down repeatedly. The sliding plate 43 disturbs the gas inside the main body 1, accelerating the heat removal speed.
[0029] The cooling fan 41 has a built-in drive motor, and the back right side of the U-shaped telescopic rod 42 is connected to the front of the cooling fan 41 shaft in a non-circular manner.
[0030] The damage prevention device 5 includes an electric slide rail 51, a carbon dioxide assembly 52, a fire sensor 53, and a spray gun 54. The electric slide rail 51 is fixedly installed on the right side of the inner wall of the main body 1. The carbon dioxide assembly 52 is slidably installed inside the electric slide rail 51 on both the upper and lower sides. The bottom of the fire sensor 53 is fixedly installed at the center of the top of the carbon dioxide assembly 52. The right side of the spray gun 54 is fixedly installed on the left side of the carbon dioxide assembly 52. The fire sensor 53 controls the electric slide rail 51 to start, and the electric slide rail 51 drives the carbon dioxide assembly 52 to move left and right. The carbon dioxide assembly 52 sprays carbon dioxide gas into the interior of the main body 1 through the spray gun 54. The carbon dioxide assembly 52 then slides left and right to expand the carbon dioxide spray range and improve the fire extinguishing effect.
[0031] The damage prevention device 5 also includes a round rod blade 55, a connecting column 56, a heating ring 57, and a filter plate 58. The right side of the round rod blade 55 is rotatably installed inside the spray gun 54. The back of the connecting column 56 is fixedly installed on the front of the outer wall of the round rod blade 55. The back of the inner wall of the heating ring 57 is fixedly installed on the front of the connecting column 56, and the outer wall of the heating ring 57 contacts the inner wall of the spray gun 54. The outer wall of the filter plate 58 is fixedly installed on the left side of the inner wall of the spray gun 54, and the right side of the filter plate 58 contacts the left side of the round rod blade 55. The spray force of the spray gun 54 causes the round rod blade 55 to generate rotational force and begin to rotate. When the round rod blade 55 rotates, it agitates the carbon dioxide gas. When the round rod blade 55 rotates, it drives the connecting column 56 to rotate. The connecting column 56 drives the heating ring 57 to rotate. By heating the carbon dioxide gas, the gas activity is increased. The filter plate 58 shields external gelatinous dirt when a fire occurs, preventing external dirt from entering the carbon dioxide assembly 52 through the spray gun 54 and causing pollution.
[0032] During use, when a short circuit occurs in the internal meter component 2 of the main body 1 after prolonged use, the cut-off component 3 automatically cuts off the circuit to prevent the circuit from catching fire. When the temperature controller 31 detects that the internal temperature of the main body 1 is too high, the temperature controller 31 controls the cooling fan 41 to start, and the cooling fan 41 draws away the heat inside the main body 1. The shaft of the cooling fan 41 drives the U-shaped telescopic rod 42 to rotate. When the U-shaped telescopic rod 42 rotates, it is restricted by the sliding plate 43 groove, causing the sliding plate 43 to slide up and down back and forth. The sliding plate 43 disturbs the gas inside the main body 1, accelerates the heat dissipation speed, and prevents the internal circuit insulation from softening due to continuous high temperature operation of the main body 1. Over time, this will shorten the service life of the circuit insulation and avoid the risk of short circuit due to exposed circuits.
[0033] When the fire sensor 53 detects a fire inside the main body 1 of the device, the fire sensor 53 controls the electric slide rail 51 to start. The electric slide rail 51 drives the carbon dioxide assembly 52 to move left and right. The carbon dioxide assembly 52 sprays carbon dioxide gas into the main body 1 through the spray gun 54. At this time, the carbon dioxide assembly 52 slides left and right to expand the carbon dioxide spray range, improve the fire extinguishing effect, shorten the fire burning time, and reduce economic losses. The spray force of the spray gun 54 causes the round rod blade 55 to generate rotational force and start to rotate. When the round rod blade 55 rotates, it agitates the carbon dioxide gas and promotes the uniformity of carbon dioxide gas spray. When plate 55 rotates, it drives connecting column 56 to rotate, which in turn drives heating ring 57 to rotate. Heating ring 57 rotates and heats the carbon dioxide gas passing through the spray gun 54, ensuring uniform heating. At the same time, heating the carbon dioxide gas increases its activity, thereby further improving the fire extinguishing effect of the carbon dioxide gas. Filter plate 58 shields external gelatinous dirt during a fire, preventing it from entering the carbon dioxide assembly 52 through the spray gun 54 and causing contamination. The round rod blade 55 rotates and scrapes the surface of filter plate 58 to ensure its cleanliness and prevents it from becoming clogged, which would prevent the carbon dioxide gas from being sprayed out.
[0034] Please see Figure 1-7 Based on the above embodiments, another embodiment of the present invention further includes an anti-deposition device 6 and an anti-adhesion device 7. The anti-deposition device 6 is disposed inside the anti-damage device 5, and the anti-adhesion device 7 is disposed below the anti-softening device 4.
[0035] The anti-deposition device 6 includes a lead screw rotating plate 61, a ring 62, and a reset plate 63. The lead screw rotating plate 61 is fixedly installed on the right side of the round rod cutter plate 55 through the left side. The ring 62 slides inside and is sleeved on the outer wall surface of the lead screw rotating plate 61. The reset plate 63 is fixedly installed between the left side of the inner wall of the carbon dioxide assembly 52 and the left side of the ring 62. When the round rod cutter plate 55 rotates, it drives the lead screw rotating plate 61 to rotate. The clockwise rotation force of the lead screw rotating plate 61 is limited by the spiral groove on the ring 62, causing the ring 62 to slide to the right along the surface of the lead screw rotating plate 61. When the reset plate 63 elastically returns to its original position, it pulls the ring 62 to reset. Similarly, when the ring 62 resets, it causes the lead screw rotating plate 61 to rotate counterclockwise. The reciprocating rotation of the lead screw rotating plate 61 agitates the carbon dioxide inside the carbon dioxide assembly 52.
[0036] The anti-deposition device 6 also includes a vertical plate 64, a rotating wheel 65, a brush rod 66, and an agitator 67. The top of the vertical plate 64 is fixedly installed on the bottom of the outer wall of the ring 62. The right side of the rotating wheel 65 is rotatably installed on the left side of the vertical plate 64, and the outer wall of the rotating wheel 65 is in contact with the bottom of the inner wall of the carbon dioxide assembly 52. The right side of the brush rod 66 is fixedly installed on the left side of the rotating wheel 65. The back of the agitator 67 is fixedly installed inside the brush rod 66. The ring 62 drives the vertical plate 64 to move left and right, and the vertical plate 64 drives the rotating wheel 65 to move synchronously. The rotating wheel 65 starts to rotate due to the friction generated by contact with the bottom of the inner wall of the carbon dioxide assembly 52. The rotating wheel 65 drives the brush rod 66 to rotate, and the brush rod 66 rotates and disturbs the carbon dioxide at the bottom of the carbon dioxide assembly 52. The brush rod 66 drives the agitator 67 to rotate, which to a certain extent increases the contact area between the brush rod 66 and the carbon dioxide assembly 52.
[0037] The anti-adhesion device 7 includes a cylinder 71, a thin film 72, and a diverter ball 73. The left side of the cylinder 71 is fixedly installed at the center of the right side of the shaft of the cooling fan 41, and an arc-shaped groove is provided on the outer wall of the cylinder 71. The back of the thin film 72 is fixedly installed on the front of the outer wall of the cylinder 71. The left side of the diverter ball 73 is fixedly installed on the right side of the cylinder 71. The shaft of the cooling fan 41 drives the cylinder 71 to rotate. When the cylinder 71 rotates, it drives the thin film 72 and the diverter ball 73 to rotate. When the thin film 72 rotates, it blocks the dirt carried by the cooling fan 41 when it is drawing air. When the diverter ball 73 rotates, the gas drawn by the cooling fan 41 is diverted and discharged by the restriction of the arc surface.
[0038] The anti-adhesion device 7 also includes a vertical rod 74, a wave plate 75, a swing plate 76, and a spring 77. The top of the vertical rod 74 is slidably installed inside the arc groove of the cylinder 71. The bottom of the wave plate 75 is slidably connected to the bottom of the inner wall of the device body 1, and the top arc surface of the wave plate 75 is fixedly installed at the bottom of the vertical rod 74. The bottom of the swing plate 76 is hinged to the right side of the arc surface of the wave plate 75. The spring 77 is fixedly installed between the right side of the swing plate 76 and the arc surface of the wave plate 75. When the cylinder 71 rotates, the arc groove restricts the vertical rod 74, allowing the vertical rod 74 to move left and right. The vertical rod 74 drives the wave plate 75 to move synchronously. The wave plate 75 disturbs the heat at the bottom of the device body 1 through its own wave arc surface, causing the heat to surge upward and preventing the heat from accumulating. The wave plate 75 drives the swing plate 76 to move synchronously. The swing plate 76 is elastically reset by the spring 77, further expanding the contact range between the wave plate 75 and the heat.
[0039] In use, when the round rod blade 55 rotates, it drives the lead screw rotating plate 61 to rotate. The clockwise rotation force of the lead screw rotating plate 61 relies on the restriction of the spiral groove on the ring 62, causing the ring 62 to slide to the right along the surface of the lead screw rotating plate 61. The ring 62 pulls the reset plate 63 to deform synchronously. Afterwards, when the reset plate 63 elastically recovers, it pulls the ring 62 to reset. Similarly, when the ring 62 resets, it causes the lead screw rotating plate 61 to rotate counterclockwise. The reciprocating rotation of the lead screw rotating plate 61 agitates the carbon dioxide inside the carbon dioxide assembly 52, preventing the carbon dioxide from accumulating due to long-term static storage. The agitation by the lead screw rotating plate 61 promotes the uniform distribution of carbon dioxide. The ring 62 drives the vertical plate 64 to move left and right, and the vertical plate 64 drives the rotating wheel 65 to move synchronously. The rotating wheel 65 begins to rotate due to the friction generated by its contact with the bottom of the inner wall of the carbon dioxide assembly 52. The rotating wheel 65 drives the brush rod 66 to rotate, which in turn agitates the carbon dioxide at the bottom of the carbon dioxide assembly 52, accelerating the mixing speed of the upper and lower parts of the carbon dioxide and preventing the deposition of carbon dioxide gas. When the brush rod 66 rotates, it drives the agitator 67 to rotate. When the agitator 67 rotates, it deforms due to the resistance generated when it contacts the bottom of the inner wall of the carbon dioxide assembly 52. After the resistance disappears, the agitator 67 recovers its elasticity, which to some extent increases the contact area between the brush rod 66 and the carbon dioxide assembly 52, thereby further agitating the carbon dioxide gas at the bottom of the carbon dioxide assembly 52.
[0040] The shaft of the cooling fan 41 drives the cylinder 71 to rotate. When the cylinder 71 rotates, it also drives the diaphragm 72 and the flow divider ball 73 to rotate. The diaphragm 72, when rotating, shields the cooling fan 41 from dirt carried during air extraction, preventing dirt from adhering to the fan blades. The flow divider ball 73, when rotating, uses its curved surface to divert the air extracted by the cooling fan 41, preventing the air from impacting the cooling fan 41 and increasing its temperature, thus avoiding frequency reduction and ensuring long-term efficient operation. The cylinder 71, when rotating, restricts the vertical rod 74 through its curved groove, allowing the vertical rod 74 to move left and right. The vertical rod 74 drives the wave plate 75 to move synchronously. The wave plate 75 disturbs the heat at the bottom of the device body 1 through its own wave arc surface, causing the heat to surge upward and preventing the heat from accumulating. This further accelerates the heat dissipation efficiency inside the device body 1. The wave plate 75 drives the swing plate 76 to move synchronously. The swing plate 76 swings in the opposite direction of the wave plate 75's sliding due to the impact force generated when the wave plate 75 slides. Then, the swing plate 76 is elastically reset by the spring piece 77. This process is repeated to further expand the contact range between the wave plate 75 and the heat, thereby further improving the heat agitation effect of the wave plate 75.
