Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, and in particular to an air purification device. Background Technology

[0002] An air disinfection and purification machine is a device used to disinfect and sterilize the air. It is commonly used in hospitals, research institutions, and other places where air disinfection is required. The air disinfection and purification machine mainly uses a compressor to dissolve disinfectant in water to form a disinfection solution, and then sprays the disinfection solution to form a disinfection mist, thereby achieving the purpose of disinfecting and purifying the air.

[0003] In existing technologies, air disinfection and purification machines continuously spray a mist of disinfectant from their nozzles during operation. However, over long periods of operation, the disinfectant mist tends to adhere to the nozzle and condense into water droplets, which eventually drip onto the equipment or the ground. Since disinfectant typically has a certain degree of adhesion, it can attract dust, requiring frequent cleaning, which is quite tedious. Therefore, an air purification device is needed to meet people's needs. Utility Model Content

[0004] To overcome the problem that in existing medical air disinfection and purification machines, disinfectant mist tends to adhere to the nozzle and condense into water droplets during long-term operation, eventually dripping onto the equipment or the floor, requiring frequent and cumbersome cleaning, this utility model provides an air purification device. The technical solution is as follows:

[0005] An air purification device includes an air purification and disinfection machine. The air purification and disinfection machine is provided with a connecting pipe, and an atomizing nozzle is connected to the end of the connecting pipe. A fixing bracket is provided on the connecting pipe and is sleeved on the outside of the atomizing nozzle. An adsorption structure is provided on the fixing bracket. An extrusion structure is provided on the connecting pipe. A collection structure is provided at the lower end of the fixing bracket.

[0006] Furthermore, the fixed bracket is box-shaped with an opening at one end away from the connecting pipe. The adsorption structure includes adsorption cotton disposed on the inner wall of the fixed bracket. The adsorption cotton is sleeved on the connecting pipe, and a squeezing plate is disposed on the outer side of the adsorption cotton. The squeezing plate has a variable diameter hole, the diameter of which gradually decreases from the inside to the outside. The atomizing nozzle is located inside the variable diameter hole. The variable diameter hole allows water droplets formed by the outermost edge of the squeezing plate to flow inward along the variable diameter hole and then be absorbed by the adsorption cotton, thereby avoiding the need for frequent cleaning of disinfectant droplets dripping onto the equipment or the ground.

[0007] Furthermore, the collection structure includes four fixed rods fixedly disposed on the bottom surface of the fixed bracket. The four fixed rods are configured in two sets and are respectively located at both ends of the fixed bracket. A baffle is fixed to the end of each fixed rod. A limiting bracket is slidably disposed on each fixed rod. A sliding block is fixed to both ends of the limiting bracket. The two sets of fixed rods pass through two sliding blocks respectively. A collection box is movably installed on the limiting bracket. The collection box has an opening at the top and is located below the fixed bracket. A communicating hole is opened on the inner bottom surface of the fixed bracket, and the communicating hole communicates with the collection box.

[0008] Furthermore, a spring is fitted onto the fixing rod, and the two ends of the spring are fixedly connected to the baffle and the sliding block, respectively.

[0009] Furthermore, the upper and lower surfaces of the inner wall of the fixed bracket are provided with limiting grooves, and the top and bottom surfaces of the extrusion plate are provided with limiting sliders that match the limiting grooves, and the limiting sliders are slidably disposed in the limiting grooves.

[0010] Furthermore, two connecting rods are provided through the fixed bracket. The end of the connecting rod away from the connecting tube passes through the absorbent cotton and the squeezing plate and has a slot. The other ends of the two connecting rods are fixed together with a connecting strip. Two flip-out clips corresponding to the slots are rotatably provided on the outer side of the squeezing plate. The flip-out clips can be locked into the slots.

[0011] Furthermore, the flip-over card strip has a rotating hole, and a rotating shaft is rotatably disposed in the rotating hole. The rotating shaft is fixedly connected to the outer side of the extrusion plate. A stop block is fixed to the outer end of the rotating shaft, and the stop block can abut against the outer side of the flip-over card strip. A torsion spring is sleeved on the rotating shaft. One end of the torsion spring is fixed to the inner wall of the rotating hole, and the other end is fixed to the rotating shaft.

[0012] Furthermore, the extrusion structure includes a fixing collar fixedly disposed on the connecting pipe, a fixing plate disposed on the fixing collar, a cylinder fixedly disposed on the side of the fixing plate away from the connecting pipe, and the output end of the cylinder being fixedly connected to the inner side of the connecting strip.

[0013] The beneficial effects of the technical solution provided by this utility model are: the device can absorb the water droplets gathered on the spray pipe by setting up structures such as adsorption cotton and extrusion plate, avoiding the need for repeated cleaning when solution droplets fall onto the equipment or the ground; and the device can squeeze out the disinfectant adsorbed on the adsorption cotton by extrusion plate in the extrusion mechanism, so that the adsorption cotton can be used continuously.

[0014] Secondly, when the absorbent cotton loses its absorbent effect, flipping the two flipping clips will release the restriction on the squeezing plate. Pulling the squeezing plate will allow the absorbent cotton to be removed from the fixed bracket, making it easy to replace the absorbent cotton.

[0015] This device also collects and stores the squeezed disinfectant through a collection box, and the collection box can be disassembled by setting a limiting bracket, making it convenient to pour out and clean the disinfectant collected inside the collection box, so as to achieve the effect of continuous use.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] See Figures 1 to 8 This utility model provides an air purification device, including an air purification and disinfection machine 100. The air purification and disinfection machine 100 is provided with a connecting pipe 101, and an atomizing nozzle 102 is connected to the end of the connecting pipe 101.

[0028] The fixed bracket 200 is box-shaped and has an opening at one end away from the connecting pipe 101. The adsorption structure includes adsorption cotton 201 disposed on the inner wall of the fixed bracket 200. The adsorption cotton 201 is sleeved on the connecting pipe 101, and a squeezing plate 202 is disposed on the outer side of the adsorption cotton 201. A variable diameter hole 212 is opened on the squeezing plate 202. The diameter of the variable diameter hole 212 gradually decreases from the inside to the outside. The atomizing nozzle 102 is located inside the variable diameter hole 212.

[0029] The collection structure includes four fixed rods 400 fixedly mounted on the bottom surface of the fixed bracket 200. The four fixed rods 400 are configured in two sets and are located at both ends of the fixed bracket 200. A baffle 401 is fixed to the end of each fixed rod 400. A limiting bracket 403 is slidably mounted on the fixed rod 400. A sliding block 402 is fixed to both ends of the limiting bracket 403. The two sets of fixed rods 400 pass through the two sliding blocks 402 respectively. A collection box 404 is movably mounted on the limiting bracket 403. The upper end of the collection box 404 is open and located below the fixed bracket 200. A connecting hole 405 is opened on the inner bottom surface of the fixed bracket 200, and the connecting hole 405 communicates with the collection box 404.

[0030] A spring 407 is fitted on the fixed rod 400, and the two ends of the spring 407 are fixedly connected to the baffle 401 and the sliding block 402 respectively.

[0031] The upper and lower surfaces of the inner wall of the fixed bracket 200 are provided with limiting grooves 206. The top and bottom surfaces of the extrusion plate 202 are provided with limiting sliders 207 that match the limiting grooves 206, and the limiting sliders 207 are slidably disposed in the limiting grooves 206.

[0032] Two connecting rods 203 are provided through the fixed bracket 200. The end of the connecting rod 203 away from the connecting tube 101 passes through the absorbent cotton 201 and the extrusion plate 202 and has a slot 204. The other ends of the two connecting rods 203 are fixed together with a connecting strip 303. Two flip strips 205 corresponding to the slots are rotatably provided on the outside of the extrusion plate 202. The flip strips 205 can be locked in the slots 204.

[0033] The flip-up clip 205 has a rotating hole 208, and a rotating shaft 209 is rotatably installed inside the rotating hole 208. The rotating shaft 209 is fixedly connected to the outer side of the extrusion plate 202. A stop block 210 is fixed to the outer end of the rotating shaft 209, and the stop block 210 can abut against the outer side of the flip-up clip 205. A torsion spring 211 is sleeved on the rotating shaft 209. One end of the torsion spring 211 is fixed to the inner wall of the rotating hole 208, and the other end is fixed to the rotating shaft 209.

[0034] The extrusion structure includes a fixing collar 300 fixedly mounted on the connecting pipe 101, a fixing plate 301 mounted on the fixing collar 300, a cylinder 302 fixedly mounted on the side of the fixing plate 301 away from the connecting pipe 101, and the output end of the cylinder 302 fixedly connected to the inner side of the connecting strip 303.

[0035] The working principle of this device is as follows: The absorbent cotton 201 absorbs the disinfectant droplets collected on the atomizing nozzle 102. When too many droplets are absorbed by the absorbent cotton 201, the cylinder 302 is activated. The cylinder 302 pushes the connecting strip 303 to move. The moving connecting strip 303 drives the two connecting rods 203 to move, which in turn causes the connecting rods 203 to move under the influence of the flipping retainer 205, thus moving the extrusion plate 202. Simultaneously, the movement of the extrusion plate 202 causes the limiting sliders 207 on both sides to slide within the limiting grooves 206 on the inner wall of the fixed bracket 200, thereby restricting the movement of the extrusion plate 202. The moving direction of the squeezing plate 202 is to prevent deviation. The moving squeezing plate 202 will squeeze the absorbent cotton 201, causing the disinfectant accumulated in the absorbent cotton 201 to be squeezed out. The squeezed disinfectant will flow into the collection box 404 through the connecting hole 405 for collection. When the collection box 404 is full, the limiting bracket 403 can be pulled down. The movement of the limiting bracket 403 will drive the sliding blocks 402 on both sides to move. The moving sliding blocks 402 will slide on the fixed rod 400 through the limiting sliding hole 406, thereby restricting the limiting bracket 403 to slide only in the vertical direction. Simultaneously, the spring 407 is compressed in conjunction with the baffle 401. The spring 407 presses the sliding block 402 and the collection box 404 against the fixed bracket 200, causing the collection box 404 to adhere tightly to the bottom of the fixed bracket 200, thus limiting the collection box 404. The continuously moving limiting bracket 403 releases the restriction on the collection box 404, allowing it to be removed and the collected disinfectant to be emptied. When the absorbent cotton 201 loses its absorbent effect, the two flip-up clips 205 can be flipped. The rotating flip-up clips 205 will pass through the rotating hole 208. Rotating on the rotating shaft 209 achieves a flipping effect. By setting the stop block 210, the flipping clip 205 can be prevented from falling off the extrusion plate 202. When the flipping clip 205 flips, it will compress the torsion spring 211 and disengage from the slot 204 on the connecting rod 203, thereby releasing the restriction on the extrusion plate 202. At this time, pulling the extrusion plate 202 can cause it to drive the absorbent cotton 201 to disengage from the fixed bracket 200, thereby realizing the disassembly of the absorbent cotton 201. Afterwards, when replacing the extrusion plate 202 and absorbent cotton 201, the installation can be carried out by following the reverse steps, which is convenient for continuous use.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
