[0044] Reference Figures 1 to 4 The present invention provides a technical solution: a self-propelled clean air circulation purification device inside an operating room, comprising:

[0045] The driving assembly 1 has driving wheels 2 installed at the four corners of its lower end surface;

[0046] The purification chamber 3 is fixed to the upper end surface of the driving assembly 1, and an air inlet 32 ​​is opened on the bottom side wall thereof, and an air outlet 31 is opened on the top thereof;

[0047] An exhaust fan 4 is rotatably arranged near the bottom of the purification chamber 3;

[0048] The purification component 5 is fixed inside the purification chamber 3 and is located above the exhaust fan 4. The upper end surface of the purification component 5 is sealed with a fixed plate 7, and an air discharge chamber is formed between the purification component 5 and the inner wall of the purification chamber 3;

[0049] A water spray pipe 6, one end of which is rotatably mounted on the fixed plate 7, and the other end of which passes through the axis of the exhaust fan 4 and extends into the driving assembly 1, and a plurality of water spray ports are equidistantly provided at the position of the water spray pipe 6 located at the purification assembly 5; and

[0050] The cleaning assembly 8 is slidably arranged on the fixed plate 7 .

[0051] It should be noted that the driving wheel 2 is controlled by a controller fixed inside the driving assembly 1, and its movement trajectory is limited by the controller, and the water pipe 6 acts as the axis of the exhaust fan 4, so that it can rotate synchronously with the exhaust fan 4.

[0052] In this embodiment, the driving assembly 1 includes:

[0053] Driving frame 11;

[0054] The bevel gear transmission compartment 12 is fixed to one side of the driving frame 11, and its input end is connected to the driving wheel 2, and its output end is fixed with a main bevel gear 13 by a rotating shaft;

[0055] Auxiliary bevel gear 14, fixed on the water spray pipe 6;

[0056] A rotary joint 16, one end of which is fixed in the driving frame 11 by a fixing column 15, and the other end of which is rotatably connected to the water spray pipe 6; and

[0057] The water tank 17 is fixed on the other side of the driving frame 11, and its top is connected to the air exhaust chamber through a circulation pipe 18, and one side of the water tank 17 is connected to the rotary joint 16 through a pipe, and a circulation pump is installed on the pipe.

[0058] As a preferred embodiment, the rotational turn ratio of the main bevel gear 13 to the auxiliary bevel gear 14 is at least one to five, and the rotational turn ratio of the main bevel gear 13 to the driving wheel 2 is one to one.

[0059] That is to say, the driving wheel 2 can provide power to the exhaust fan 4 through the bevel gear transmission chamber 12, and the rotation speed of the exhaust fan 4 can be increased through the main bevel gear 13 and the auxiliary bevel gear 14, thereby increasing the exhaust efficiency.

[0060] Among them, when the driving wheel 2 rotates, the main bevel gear 13 is rotated through the bevel gear transmission chamber 12, thereby rotating the auxiliary bevel gear 14 engaged with the main bevel gear 13. At this time, the water spray pipe 6 rotates through the auxiliary bevel gear 14 and drives the exhaust fan 4 to rotate and extract air. At the same time, the circulation pump is turned on to inject water into the inside of the 2 water spray pipes 6 to discharge large particles of impurities in the air, and the purification component 5 is preliminarily cleaned by spraying water through the water spray pipe 6.

[0061] In this embodiment, the purification component 5 includes:

[0062] The collecting ring 51 is fixed to the bottom of the purification chamber 3 and has a plurality of water filter openings formed on its outer wall. The water filter openings are connected to the air exhaust chamber.

[0063] The purification ring 52 is fixed to the upper end surface of the collecting ring 51 and is composed of at least three layers of filter screens;

[0064] A communication ring 53 is fixed on the inner wall of the collecting ring 51;

[0065] A collecting chamber 54 is detachably mounted on the bottom of the collecting ring 51 and is slidable in the purification chamber 3; and

[0066] The ejection ring 55 is fixed inside the communication ring 53 and close to the collecting ring 51 .

[0067] As a preferred embodiment, the inner circle of the connecting ring 53 close to the water spray pipe 6 is in a grid shape to facilitate the entry of air, the outer circle of the connecting ring 53 is a hollow ring tube, and the overall top surface of the connecting ring 53 is a conical surface.

[0068] As a preferred embodiment, the cleaning component 8 includes:

[0069] There are at least two lifting columns 81, both slidably disposed in the fixed plate 7, and a lifting ring is fixed on the top of each column;

[0070] Temporary storage components 82 are fixed to the lower end surface of the lifting column 81, and the number is the same as the lifting column 81;

[0071] a scraper ring 83 fixed to the circumferential outer wall of the plurality of temporary storage components 82; and

[0072] The scraping brush 84 is fixed to the end of the scraping ring 83 away from the temporary storage assembly 82 and is in contact with the inner wall of the cleaning ring 52 .

[0073] That is to say, after the air purification in the operating room is completed, the lifting ring is pulled to make the lifting column 81 slide upward, thereby driving the scraping ring 83 to slide, so that the scraping brush 8 performs a secondary cleaning on the inner wall of the purification ring 52 to avoid the accumulation of large particles of impurities. After cleaning, the lifting ring is pressed to reset the scraping ring 83, and the temporary storage component 82 is in contact with the connecting ring 53, so that the large particles of impurities in the air pass through the temporary storage component 82, the connecting ring 53 and the collecting ring 51 into the collecting bin 54 to wait for processing, and the excess water is discharged into the air discharge bin through the water filter port, and enters the water tank 17 through the circulation pipe 18 for circulation.

[0074] As a preferred embodiment, the temporary storage component 82 includes:

[0075] Temporary storage warehouse 821;

[0076] A fixed plate 822, fixed in the temporary storage bin 821 at a position away from the ejection ring 55;

[0077] a sliding plate 823 slidably disposed in the temporary storage bin 821 near the ejection ring 55 and located above the ejection ring 55 ; and

[0078] The sliding column 824 has one end slidingly disposed in the sliding plate 823 and the other end fixed in the fixed plate 822 .

[0079] As a preferred embodiment, the fixed plate 822 and the sliding plate 823 are two semicircular shapes, and guide slopes are provided on opposite sides of the fixed plate 822 and the sliding plate 823, and when the sliding plate 823 is not subjected to external force, the two guide slopes fit together and seal.

[0080] That is, when the temporary storage assembly 82 contacts the connecting ring 53, the ejection ring 55 causes the sliding plate 823 to slide, thereby opening the two guide slopes, allowing the cleaned large particles of impurities to enter the connecting ring 53 through the guide slopes for discharge.

[0081] Specifically, first, the motion trajectory of the driving wheel 2 is set by the controller so that it moves in the operating room, which greatly increases the range and efficiency of air purification. The rotation of the driving wheel 2 can directly drive the exhaust fan 4 to rotate and extract air, saving costs. After the air enters the purification component 5, the rotating water spraying of the water pipe 6 can increase the water content of large particle impurities in the air, increase the weight of large particle impurities, and prevent them from escaping in the air. The purification ring 52 can be preliminarily cleaned by spraying water on it, and the sprayed water returns to the water tank 17 through the circulation pipe 18 for circulation, which improves the water utilization rate. After the air purification in the operating room is completed, the scraping brush 84 is pulled by pulling the lifting ring to perform a secondary cleaning on the inner wall of the purification ring 52 to avoid the accumulation of large particle impurities. The cleaned large particle impurities enter the collection bin 5 through the connecting ring 53 and the collecting ring 51 to wait for processing, and the excess water is discharged through the water filter port.

[0082] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
