Description

Technical Field

[0001] The utility model relates to the technical field of fresh air purification, in particular to a fresh air purification device for an operating room. Background Art

[0002] The fresh air purification system is composed of a fan, an air inlet, an exhaust outlet and various pipes and joints. When the fan is started, the polluted air in the room is discharged to the outside through the exhaust outlet and the fan, so that negative pressure is formed in the room, and the fresh air outside enters the room through the air inlet installed between the window frame and the wall above the window frame. The air outlet mechanism on the existing fresh air purification system is generally connected with a snap buckle, which can be installed and disassembled when in use. However, for some non-professionals, they do not understand the specific structure of the snap buckle and do not know how to use force to remove it, and it takes a long time to remove it.

[0003] As disclosed in Chinese patent announcement No. CN220648551U, an operating room fresh air purification device, when in use, the mounting shell and the air outlet mechanism can be connected by adsorbing the second magnet through the first magnet, so that the air outlet mechanism can be easily disassembled and cleaned during use, and it can be easily installed after cleaning. The direction of the first magnet is rotated, and when the first magnet is located at the front end of the air outlet pipe, it can be adsorbed with the second magnet. When the air outlet mechanism needs to be removed from the mounting shell, the motor can be turned on again to make the shaft rotate in the opposite direction, and the placement shell can be rotated in the opposite direction, so that one side of the first magnet installed on the placement shell is flipped to the inside of the groove, and the first magnet is separated from the second magnet, so that the air outlet mechanism is separated from the mounting shell, and it is easy to disassemble it.

[0004] However, the operating room fresh air purification device in the above application is only provided with a set of disassembly mechanisms. As air pollution intensifies, the incoming air needs to be filtered and purified. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a kind of operating room fresh air purification device. Utility Model Content

[0006] The purpose of the utility model is to provide an operating room fresh air purification device to solve the problem that the operating room fresh air purification device proposed in the above background technology is only provided with a set of disassembly mechanisms, and as the air pollution intensifies, the new air needs to be filtered and purified.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an operating room fresh air purification device, comprising an air inlet pipe and an air inlet, wherein the air inlet is fixedly connected to the left center of the air inlet pipe, and a purification device is arranged inside the air inlet pipe.

[0008] The purification device includes a filtering unit and a dust removal unit.

[0009] The filter unit includes a mounting block, a vibration spring, a dustproof net, and a vibration assembly. The four mounting blocks are respectively fixedly connected to the upper and lower ends inside the front and rear sides of the air inlet pipe, the four vibration springs are respectively fixedly connected to the left side of the mounting blocks, the dustproof net is fixedly connected to the left side of the vibration spring, and the vibration assembly is installed on the top of the air inlet pipe.

[0010] A further improvement is that the vibration component includes a rotating motor, a rotating bearing, a rotating shaft, and an arc-shaped plate. The rotating motor is installed at the top of the air inlet duct, and the rotating bearing is installed inside the top of the air inlet duct. The rotating shaft is connected to the output end of the rotating motor and is rotatably connected to the inside of the rotating bearing, and its bottom extends into the inside of the air inlet duct. The arc-shaped plate is fixedly connected to the bottom of the rotating shaft, and large particles of dust and impurities in the newly incoming air are intercepted and filtered through the dustproof net. After the dustproof net has been used for a long time, the rotating motor is started to drive the rotating shaft to rotate inside the rotating bearing, thereby driving the arc-shaped plate at the bottom of the rotating shaft to rotate and hit the dustproof net, thereby driving the dustproof net to swing left and right on the vibration spring, thereby shaking off the dust adhered to the surface of the dustproof net, avoiding dust clogging the dustproof net, thereby affecting the filtering and dustproof effect.

[0011] A further improvement is that the dust removal unit includes an electrostatic dust removal plate, a vibration motor, and a stretching assembly. The electrostatic dust removal plate is installed on the inner left side of the air inlet duct, the vibration motor is installed on the top of the electrostatic dust removal plate, and the two groups of stretching assemblies are respectively fixedly connected to the front and rear ends of the electrostatic dust removal plate.

[0012] A further improvement is that the stretching assembly includes a limiting sleeve, a limiting slide rod, and a stretching spring, the limiting sleeve is fixedly connected to the top wall of the air inlet duct, the limiting slide rod is slidably connected to the inner bottom of the limiting sleeve, the stretching spring is fixedly connected between the top wall of the air inlet duct and the top of the electrostatic dust removal plate, and is installed on the outside of the limiting sleeve, so that the electrostatic dust removal plate can further intercept fine dust in the air, and after the electrostatic dust removal plate has been used for a long time, the vibration motor is started to drive the electrostatic dust removal plate to vibrate up and down under the pull of the stretching spring, thereby shaking off the dust adhered to the surface of the electrostatic dust removal plate, avoiding affecting the electrostatic dust removal effect of the electrostatic dust removal plate.

[0013] A further improvement is that a dust outlet is provided at the bottom of the air inlet duct, and a dust collecting box is installed inside the dust outlet. Dust shaken off the dustproof net and the electrostatic dust removal plate falls through the dust outlet into the dust collecting box for collection, and the dust collecting box can be removed and cleaned regularly.

[0014] A further improvement is that an activated carbon plate is installed on the left side of the inside of the air inlet pipe, and air holes are evenly opened on the outer surface of the activated carbon plate. The air after filtering and dust removal passes through the air holes opened on the activated carbon plate, thereby adsorbing and purifying odors and some harmful gases in the air.

[0015] A further improvement is that a push-pull groove is opened on the front of the air inlet pipe, and the activated carbon board is movably connected to the inside of the push-pull groove. Because the activated carbon board has its adsorption limit, the activated carbon board can be taken out from the inside of the push-pull groove regularly for replacement.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The fresh air purification device in the operating room intercepts and filters large dust particles in the incoming air through a dust-proof net. After the dust-proof net has been used for a long time, the rotating motor is started to drive the rotating shaft and the arc plate at the bottom to rotate and hit the dust-proof net, thereby driving the dust-proof net to swing left and right on the vibration spring, thereby shaking off the dust adhering to the surface of the dust-proof net to prevent the dust from clogging the dust-proof net.

[0018] 2. The fresh air purification device in the operating room further intercepts the fine dust in the air through the electrostatic dust removal plate. After the electrostatic dust removal plate has been used for a long time, the vibration motor is started to drive the electrostatic dust removal plate to vibrate up and down under the pull of the tension spring, thereby shaking off the dust adhered to the surface of the electrostatic dust removal plate.

[0019] 3. The fresh air purification device in the operating room allows the air after filtering and dust removal to pass through the air permeable holes opened on the activated carbon board, thereby adsorbing and purifying the odor and some harmful gases in the air. Because the activated carbon board has its adsorption limit, the activated carbon board can be taken out from the inside of the push-pull groove regularly for replacement.
