[0014] The present invention provides a wall-mounted voltage stabilizer with a dustproof structure. It has the following beneficial effects:

[0015] (1) In the present invention, the gas entering the machine body from the outside will first be filtered through the filter plate to prevent dust and impurities from entering the machine body and causing short circuit or damage to the electrical components. The transmission shaft is driven by the motor, and the transmission shaft drives the two-way column to rotate. When the two-way column rotates, the two-way column drives the guide block to move in the thread groove of the two-way column.

[0016] (2) The invention can dissipate heat inside the machine body and remove static electricity inside the machine body through the ion fan. Removing static electricity can effectively prevent damage to electrical components inside the machine body. The transmission shaft can drive the paddle to rotate by rotating the transmission shaft. When the paddle rotates, the paddle will drive the paddle to rotate. The rotation of the paddle will drive the threaded column to rise. When the threaded column rises, the threaded column will drive the guide plate to rotate. When the guide plate rotates, the wind direction blown out from the ion fan can be changed. The area blown by the ion fan becomes larger, which can achieve better heat dissipation.

[0017] (3) The invention can drive the lever to rotate by rotating the guide plate. When the lever rotates, the lever can contact the push rod. When the lever contacts the push rod, the push rod will push the air in the hollow chamber. At this time, the air will push the boss to move to the right. When the boss moves to the right, the boss will drive the baffle to rotate. At this time, the baffle will contact the baffle plate and be blocked by the baffle plate. Since the power of the motor comes from the inside of the voltage stabilizer, the protection door will not be opened when the voltage stabilizer is working normally. The protection door will be opened only when the voltage stabilizer is damaged or short-circuited. This can effectively prevent the protection door from being opened illegally or by children to prevent injuries to the children. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 11 One embodiment of the present invention is: a wall-mounted voltage stabilizer with a dustproof structure, including a body 1, and also including a dustproof device; wherein the dustproof device includes a motor 21, a transmission shaft 22, a bidirectional column 23, a filter plate 24, a scraper 25, a guide block 26, a collection tank 27, a collection bin 28, a guide rod 29 and a protrusion 210, the motor 21 is fixedly connected to the top of the body 1, the transmission shaft 22 is fixedly connected to the output end of the motor 21, the bidirectional column 23 is fixedly connected to the circumferential surface of the transmission shaft 22, the filter plate 24 is fixedly connected to the inside of the body 1, the guide rod 29 is fixedly connected to the inside of the body 1, and the scraper 25 is slidably connected to the filter plate 24, the guide block 26 is rotatably connected to the right side of the scraper 25, the protrusion 210 is fixedly connected to the front side of the scraper 25, the collecting tank 27 is fixedly connected to the bottom of the body 1, and the collecting bin 28 is slidably connected to the inside of the collecting tank 27. The gas entering the body 1 from the outside will first be filtered through the filter plate 24 to prevent dust and impurities from entering the body 1 and causing short circuit or damage to electrical components. When the guide block 26 moves, the guide block 26 will drive the scraper 25 to move up and down. When the scraper 25 moves up and down, the scraper 25 will clean the filter plate 24 to prevent excessive impurities on the surface of the filter plate 24 from clogging the filter plate 24.

[0032] The protrusion 210 is slidably connected between the two guide rods 29, and the scraper 25 is in contact with the filter plate 24. The protrusion 210 can keep the scraper 25 in a horizontal state to move.

[0033] A long groove is provided at the bottom of the machine body 1 , and a thread groove is provided on the circumferential surface of the bidirectional column 23 , along which the guide block 26 moves.

[0034] When the present embodiment is working, when the motor 21 is started, the output end of the motor 21 drives the transmission shaft 22 to rotate, when the transmission shaft 22 rotates, the transmission shaft 22 drives the bidirectional column 23 to rotate, when the bidirectional column 23 rotates, the bidirectional column 23 drives the guide block 26 to move in the thread groove of the bidirectional column 23, when the guide block 26 moves in the thread groove of the bidirectional column 23, the guide block 26 drives the scraper 25 to move, when the scraper 25 moves, the scraper 25 drives the protrusion 210 to move, when the protrusion 210 moves, the protrusion 210 moves along the track between the two guide rods 29 The scraper 25 slides up and down. When the protrusion 210 slides up and down along the track between the two guide rods 29, the protrusion 210 drives the scraper 25 to move up and down. When the scraper 25 moves up and down, the scraper 25 scrapes the impurities and dust on the right side of the filter plate 24 to prevent the impurities and dust from clogging the filter plate 24. When the scraper 25 scrapes the impurities and dust up and down, the scraper 25 scrapes the impurities and dust off. When dust is scraped off, the dust falls into the collecting bin 28 for collection to prevent the dust from falling directly onto the bottom wall inside the body 1 and causing accumulation. The collecting bin 28 can be taken out by pulling the collecting bin 28 forward to process the dust and impurities.

[0035] See also Figure 1-Figure 11 On the basis of the above embodiment, another embodiment of the present invention further includes a heat dissipation device and a protective device. The heat dissipation device includes an ion fan 31, a frame 32, a guide plate 33, a paddle 34, a paddle 35, a cylinder 36, a threaded column 37, a support rod 38, a support column 39 and a connecting block 310. The ion fan 31 is fixedly connected to the right side of the body 1, the frame 32 is fixedly connected to the body 1, the support rod 38 is fixedly connected to the frame 32, the guide plate 33 is rotatably connected to the circumferential surface of the support rod 38, the connecting block 310 is fixedly connected to the rear of the guide plate 33, the support column 39 is rotatably connected to the rear of the connecting block 310, and the paddle 34 is fixedly connected to The circumferential surface of the transmission shaft 22, the cylinder 36 is rotatably connected to the bottom wall inside the body 1, the threaded column 37 is rotatably connected to the inside of the cylinder 36, and the paddle 35 is fixedly connected to the circumferential surface of the cylinder 36. The ion fan 31 can dissipate heat inside the body 1, and can also remove static electricity inside the body 1. Removing static electricity can effectively prevent damage to the electrical components inside the body 1. The rotation of the paddle 35 will drive the threaded column 37 to rise. When the threaded column 37 rises, the threaded column 37 will drive the guide plate 33 to rotate. When the guide plate 33 rotates, the wind direction blown out from the ion fan 31 can be changed. The area blown by the ion fan 31 becomes larger, which can achieve better heat dissipation.

[0036] The top of the threaded column 37 contacts the bottom of the support column 39, and the threaded column 37 is threadedly connected to the cylinder 1 36. When the cylinder 1 36 rotates, the thread on the inner wall of the cylinder 1 36 drives the threaded column 37 to rise.

[0037] The protection device includes a protection door 41, a handle 42, a baffle 43, a baffle 44, a hollow bin 45 cylinder 411, a one-way valve 412 and a lever 413. The protection door 41 is rotatably connected to the front side of the body 1, the handle 42 is fixedly connected to the front side of the protection door 41, the baffle 43 is fixedly connected to the right wall inside the body 1, the baffle 44 is rotatably connected to the rear of the protection door 41, the hollow bin 45 is fixedly connected to the right side of the frame 32, the one-way valve 412 is fixedly connected to the front side of the hollow bin 45, the cylinder 411 is fixedly connected to the right side of the hollow bin 45, and the lever 413 is fixedly connected to the front of the guide plate 33. Since the power of the motor 21 comes from the inside of the voltage stabilizer, the protection door 41 will not be opened when the voltage stabilizer is working normally, and the protection door 41 will only be opened when the voltage stabilizer is damaged or short-circuited, which can effectively prevent the protection door 41 from being illegally opened or opened by children to prevent harm to the children.

[0038] The protective device also includes a push rod 46, a spring 1 47, a thin sheet 48, a spring 2 49 and a boss 410. The push rod 46 is slidably connected to the inside of the hollow bin 45, the thin sheet 48 is fixedly connected to the inside of the hollow bin 45, the top of the spring 1 47 is fixedly connected to the bottom of the push rod 46, the bottom of the spring 1 47 is fixedly connected to the top of the thin sheet 48, the boss 410 is slidably connected to the inside of the cylinder 2 411, the left side of the spring 2 49 is fixedly connected to the left side of the inside of the hollow bin 45, and the right side of the spring 2 49 is fixedly connected to the left side of the boss 410. When the lever 413 contacts the push rod 46, the push rod 46 will push the air in the hollow bin 45, and the air will push the boss 410 to move to the right. When the boss 410 moves to the right, the boss 410 will drive the baffle 44 to rotate, and the baffle 44 will contact the baffle 43, and the baffle 44 will be blocked by the baffle 43.

[0039] A circular hole is formed inside the protruding column 410 , and the baffle 44 contacts the baffle plate 43 , so that the excess air in the hollow chamber 45 is discharged through the circular hole.

[0040] When the present embodiment is working, when the transmission shaft 22 rotates, the transmission shaft 22 drives the paddle plate 34 to rotate; when the paddle plate 34 rotates, the paddle plate 34 contacts the paddle 35; when the paddle plate 34 contacts the paddle 35, the paddle 35 is pushed by the paddle plate 34; when the paddle plate 34 pushes the paddle 35, the paddle 35 rotates; when the paddle 35 rotates, the paddle 35 drives the cylinder 1 36 to rotate; when the cylinder 1 36 rotates, the threads in the cylinder 1 36 contact the threads in the threaded column 37; when the threads in the cylinder 1 36 contact the threads in the threaded column 37, the threaded column 37 is pushed out by the cylinder 1 36; when the threaded column 37 When being pushed out by cylinder 1 36, threaded column 37 will contact with support column 39. When threaded column 37 contacts with support column 39, support column 39 will be pushed upward by threaded column 37. When support column 39 moves upward, support column 39 will drive connecting block 310 to rotate. When connecting block 310 rotates, connecting block 310 will drive guide plate 33 to rotate. When guide plate 33 rotates, guide plate 33 can change the wind direction blown by ion fan 31. When guide plate 33 changes the wind direction blown by ion fan 31, guide plate 33 can expand the area blown by ion fan 31, so as to better dissipate heat and prevent voltage stabilizer from overloading.

[0041] When the guide plate 33 rotates, the guide plate 33 drives the lever 413 to rotate. When the lever 413 rotates, the lever 413 contacts the top of the push rod 46. When the lever 413 contacts the top of the push rod 46, the push rod 46 is pushed downward by the lever 413. When the push rod 46 is pushed downward by the lever 413, the push rod 46 pushes the gas inside the hollow chamber 45. When the gas inside the hollow chamber 45 is pushed by the push rod 46, the air pushes the protruding column 410. When the air When the boss 410 is pushed, the boss 410 moves to the right. When the boss 410 moves to the right, the boss 410 contacts the baffle 44. When the boss 410 contacts the baffle 44, the baffle 44 is pushed by the boss 410. When the boss 410 pushes the baffle 44, the baffle 44 rotates. When the baffle 44 rotates, the baffle 44 contacts the back of the baffle 43. When the baffle 44 contacts the back of the baffle 43, the baffle 43 blocks the baffle 44. When the baffle 43 blocks When the blocking piece 44 is in the state of protecting the door 41 from being opened, when the lever 413 is out of contact with the push rod 46, the push rod 46 is pushed upward by the spring 1 47. When the push rod 46 moves upward, the external air enters the hollow chamber 45 through the one-way valve 412. The material of the protrusion 410 is rubber. The friction between the protrusion 410 and the cylinder 2 411 is relatively large. Therefore, when the protrusion 410 is not retracted, the push rod 46 starts to move downward again. At this time, the excess air will pass through the protrusion 410. The electric power of the motor 21 comes from the inside of the voltage stabilizer. When the electronic components inside the voltage stabilizer are damaged or tripping occurs, the motor 21 will stop working. When the motor 21 stops working, the guide plate 33 will stop rotating. When the guide plate 33 stops rotating, the push rod 46 will stop moving. When the push rod 46 stops moving, the boss 410 will be slowly retracted by the spring 2 49. When the boss 410 is retracted, the baffle 44 will remain in a vertical state under the influence of gravity.
