[0030] In order to make the technical solutions and advantages of the present application more clear, the present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 10 As shown, the air-purifying gas-impacting negative oxygen ion air-discharging machine of the present application includes a main body 100 and a blowing part 200, wherein the blowing part 200 is located above the main body 100. The main body 100 and the blowing part 200 are detachably connected, for example, by threaded connection, clamping, etc.

[0032] The main body 100 includes a main body shell 101, the main body shell 101 has a chamber inside, and an air pump 300 is arranged in the chamber; the blowing part 200 includes a blowing part shell 201, an exhaust fan 400 and an air-shock negative oxygen ion generator 500, wherein the exhaust fan 400 is installed in the blowing part shell 201, and the air-shock negative oxygen ion generator 500 is installed inside or outside the blowing part shell 201; for example, the blowing part shell 201 and the main body shell 101 are both square straight-through cylinders, and the lower end of the blowing part shell 201 is fixedly connected to the upper end of the main body shell 101 by screws or buckles, and a sealing vibration-damping strip is arranged at the connection part. The exhaust fan 400 is arranged at the center of the blowing part shell 201, and an isolation net or isolation window is arranged at the upper end of the blowing part shell 201 to prevent foreign objects from entering and damaging the blades of the exhaust fan 400 and causing safety hazards.

[0033] Among them, the air pump 300 is connected to the air-shock type negative oxygen ion generator 500, and is used to provide compressed gas to the air-shock type negative oxygen ion generator 500; the exhaust fan 400 is used to draw air from the main body 100 and blow it out from the air outlet 202 of the blowing part 200; the negative oxygen ion outlet 501 of the air-shock type negative oxygen ion generator 500 is aligned with the air outlet 202 of the blowing part 200.

[0034] During operation: the air pump 300 is started to generate compressed gas which is provided to the air-impact negative oxygen ion generator 500, and impacts with the water inside to generate negative oxygen ion gas, which is ejected from the negative oxygen ion outlet 501. At the same time, the exhaust fan 400 is working, which draws air from the main body 100 and blows it out from the outlet 202 of the blowing part 200. The high-speed gas collides with the negative oxygen ion gas, driving the negative oxygen ion gas to move to a distant place, thereby increasing the diffusion speed of the negative oxygen ion gas.

[0035] The air-purifying air-impacting negative oxygen ion air discharger of the present application adopts a modular design structure, the main body 100 and the blowing part 200 are detachably connected, and the structural design is reasonable, which is convenient for installation, disassembly and maintenance, and does not affect the overall working performance. In addition, the air extracted by the exhaust fan 400 in the present application enters the chamber from the lower part of the main body 100 and flows through the periphery of the air pump 300, which can take away the heat generated by the pump 300 and cool the pump 300, avoiding damage caused by the heat not being able to dissipate when the pump 300 is working, and there is no need to set up a separate cooling component, which reduces costs.

[0036] In one embodiment, the air outlet 202 is located at the top of the blowing part 200, the rotating shaft 420 of the exhaust fan 400 is vertically arranged, and the negative oxygen ion outlet 501 of the air impact negative oxygen ion generator 500 is horizontally arranged, so that the negative oxygen ion gas vertically collides with the gas at the air outlet 202. With such a solution, the airflow path of the exhaust fan 400 is from bottom to top without bending, and the airflow is smoother.

[0037] In one embodiment, the main body 100 includes an inner shell 110, the inner shell 110 is arranged in the main body shell 101, and the air pump 300 is arranged in the inner shell 110; wherein, the inner shell 110 includes a bottom wall 111 and a cylindrical side wall 112 arranged above the bottom wall, an air inlet 113 is provided on the bottom wall, the inner diameter of the side wall 112 is a conical structure with a large upper radius and a small lower radius, and there is a gap between the lower end of the inner surface of the side wall 112 and the air pump 300 (the radius here refers to the equivalent radius, if it is a non-circular shape such as a rectangle or a polygon, it is the average value of the distance from the center to each side). Among them, the inner shell 110 generally adopts a molded plastic part, and a metal stamping part can also be used. With such a scheme, there is a significant suction effect on the airflow of the air inlet 113, so that the cooling effect on the air pump 300 is better, and the airflow entering the exhaust fan 400 is also large. In one embodiment, the inner shell 110 further includes a reinforcing rib 114 and an outer wall 115 provided inside. The outer wall 115 and the side wall 112 form a triangular structure, which enhances the strength of the inner shell 110 as a whole.

[0038] In one embodiment, it also includes an air pump cover 310, which is a cylindrical structure, and its upper end is fixed to the blowing part housing 201. The air pump 300, the air inlet vibration damping muffler 321 and the air outlet vibration damping muffler 320 are arranged in the air pump cover 310, wherein the air inlet vibration damping muffler 321 is arranged at the bottom of the air pump cover 310 and connected to the air inlet of the air pump 300, and the air outlet of the air pump 300 is connected to the air outlet vibration damping muffler 320. In one embodiment, it also includes an air pump vibration damping device 330, wherein the air pump 300 is fixed to the bottom of the air pump cover 310 or arranged on the partition of the side wall of the air pump cover 310 through the air pump vibration damping device, and the material of the air pump vibration damping device is spring or rubber. With this solution, the air pump 300 is suspended on the blowing part 200 and has no fixed connection with the main body 100. The vibration of the air pump 300 passes through the blowing part 200 and is connected to the main body 100 for vibration reduction. In this way, the vibration is basically not directly transmitted to the bottom surface through the main body 100, thereby reducing vibration noise.

[0039] In one embodiment, the air pump cover 310 is elastically connected to the blowing part housing 201. In a preferred embodiment, multiple vibration reduction assemblies 700 shown in the figure are used for connection, for example, three or four, which are evenly arranged around the top of the air pump cover 310. Specifically, the vibration reduction assembly 700 includes an elastic sleeve 710 and a support rod 720, a mounting hole for mounting the vibration reduction assembly 700 is provided at the bottom of the blowing part housing 201, and a connecting bracket 311 is provided on the side wall of the air pump cover 310, wherein the elastic sleeve 710 is partially arranged through the mounting hole and supported by the blowing part housing 201 at the edge of the mounting hole, and the support rod 720 is arranged in the elastic sleeve 710, wherein the top 721 of the support rod 720 is a thick diameter structure, supported on the top of the elastic sleeve 710, the middle section 722 of the support rod 720 is sleeved in the elastic sleeve 710, and the lower end 723 of the support rod 720 is fixedly connected to the connecting bracket 311 (for example, a threaded structure is used). With such a structure, the air pump 300, the air pump cover 310, the muffler and other components are not in direct contact with the blowing part housing 201, and their weight is transferred to the support rod 720 through the connecting bracket 311, and then transferred to the elastic sleeve 710 through the top of the support rod 720, and then transferred to the blowing part housing 201 through the elastic sleeve 710. During the working process, the vibration force is also transmitted in the same way, and is absorbed by the elastic sleeve 710 during the transmission process, thereby reducing the vibration and achieving a better vibration reduction effect.

[0040] In one embodiment, the elastic sleeve 710 includes a support portion 711, a clamping portion 712 and a through portion 713, wherein the through portion 713 is a conical structure, the maximum outer diameter of which is slightly larger than the diameter of the mounting hole, and the cross-sectional thickness is smaller than the cross-sectional thickness of the clamping portion 712 and the support portion 711; the outer diameter of the clamping portion 712 is adapted to the diameter of the mounting hole; the outer diameter of the support portion 711 is larger than the diameter of the mounting hole, and the cross section of the support portion 711 is a serpentine structure, and the outer diameter of the portion in contact with the shell 201 of the blowing portion is larger than the outer diameter of the other parts of the elastic sleeve 710. During installation, the through portion 713 of the elastic sleeve 710 gradually passes through the mounting hole, and its maximum outer diameter is deformed to pass through the mounting hole, and then the clamping portion 712 enters the mounting hole and clamps the support portion 711 on the mounting hole. With such a structure, the vibration reduction effect is better, and the elastic sleeve 710 is more stable during operation, and no local collapse occurs. And the installation is simpler and more convenient, and the elastic sleeve 710 is not easy to fall out of the mounting hole.

[0041] In one embodiment, a filter barrel 120 is provided inside the inner shell of the main body 100 for accommodating the air pump cover 310 therein. The filter barrel 120 is made of a fiber cloth with a smaller pore size, a sponge or other material wrapped on a fixed frame, and the filter barrel 120 includes a barrel body 121 and a filter barrel connector 122 fixedly connected to its upper end. A positioning connection part 220 is provided at the bottom of the spraying part shell 201, and the positioning connection part 220 is an annular structure or a plurality of arc structures (for example, a plurality of arcs formed by a plurality of notches on the annular structure), and the filter barrel connector 122 can be fixedly connected to the positioning connection part 220. The fixed connection can be a spiral connection. It can also be a snap connection, for example, the upper end of the filter barrel connector 122 includes a lateral protrusion, and the whole has a certain elasticity, and a groove is provided at a part of the positioning connection part 220, and the lateral protrusion can pass through the inner cavity of the positioning connection part 220 as the filter barrel connector 122 is deformed, and the groove is restored to its original shape and snapped with the groove. With this solution, air can enter the air pump cover 310 only after passing through the filter barrel 120, and dust particles in the air can be filtered out, making the air entering the air pump 300 and the exhaust fan 400 purer, thereby avoiding damage to the air shock type negative oxygen ion generator 500 and the exhaust fan 400. In addition, the above installation method is simpler and more convenient.

[0042] In one embodiment, a primary filter 130 is provided at the lower end of the main body shell 101. Preferably, the primary filter 130 is located 5 to 30 mm below the air inlet at the bottom of the inner shell. The primary filter 130 is used to filter large particles of dust, and is generally made of sponge, coarse fiber cloth and other materials. The primary filter can be removed for cleaning or replacement.

[0043] In one embodiment, the air conditioner further includes a base 600, which is disposed below the main body 100 and can be connected to the main body 100 by screw connection, snap connection, threaded connection, etc. The base 600 is a hollow structure, with openings disposed on at least one side wall and a top wall, and air can enter the hollow structure from the opening of at least one side wall, and pass through the primary filter 130 from the opening of the top wall into the main body 100.

[0044] In one embodiment, a vibration-damping sealing strip is provided at the connection portion between the blowing part housing 201 and the main body housing 101, so as to achieve both sealing of the entire device and vibration reduction between the blowing part 200 and the main body 100.

[0045] In one embodiment, the gas shock type negative oxygen ion generator 500 includes a gas shock device 510, a water container 520 and a top cover 530. The gas shock device 510 is arranged in the inner cavity of the water container 520 and immersed under the water surface of the water container 520. The gas shock device 510 is suspended and fixed by an air inlet pipe 540; the gas shock device 510 is a structure with an inner cavity, including an upper cover 511 and a lower bottom 512, a gas shock hole 513 is opened on the upper cover 511, and water absorption holes 514 are arranged around the gas shock hole; the air inlet pipe 540 is connected with the gas shock hole 513, and is used to allow compressed gas to enter the inner cavity of the gas shock device 510 through the gas shock hole 513; one end of the water absorption hole 514 is connected with the gas shock hole 513, and the other end is connected with the inner cavity of the water container 520; an air shock plate 516 is arranged on the lower bottom 512 in front of the gas shock hole 513. During operation, compressed air (oxygen) is delivered to the air striking hole 513 along the air inlet pipe 540, and the compressed air is ejected at high speed from the air striking hole 513. Since the gas has a high flow rate in the air striking hole 513, a negative pressure is formed according to the Bernoulli equation principle, so that the water in the water container 520 is ejected at high speed from the outlet end of the air striking hole 513 along the water absorption hole 514 together with the compressed air, and hits the water and the air striking plate 516, generating high-concentration and high-humidity negative oxygen ion gas. Preferably, the diameter of the air striking hole 513 is 0.5 to 3 mm, the diameter of the water absorption hole 514 is generally 10 to 50% of the air striking hole 513, and the air striking plate 516 is arranged 3 to 10 mm in front of the air striking hole 513.

[0046] In one embodiment, the gas striking hole 513 includes a first section 5131, a second section 5132 and a third section 5133 from top to bottom, wherein the diameter of the second section is 1.5-2 times that of the first section 5131, the water absorption hole 514 is connected to the second section 5132, and the diameter of the third section 5133 is slightly larger than the first section 5131, for example, less than 1.1 times the diameter of the first section 5131. With such a scheme, after the gas passes through the gas striking hole 513, it drives the water to gather from the water absorption hole 514 to the second section, and is ejected from the third section 5133 together with the gas, and such a size design makes the effect of gas driving water better, and the concentration of negative oxygen ion gas generated by gas striking is also higher.

[0047] In one embodiment, an air guide hole 515 is provided at the edge of the upper cover 511, an air guide tube 550 is installed on the air guide hole 515, and a dewatering plate 560 is provided at the outlet of the air guide tube 550. With such a scheme, the high-concentration and high-humidity negative oxygen ion gas rises along the air guide tube 550, and continues to rub and collide in the air guide tube 550. According to the principle of friction electrification, the compressed air is constantly in contact with and separated from the tube wall of the air guide tube 550, and is negatively charged, further increasing the concentration of negative oxygen ions, which can reach more than 10 million per cubic centimeter. The high-concentration and high-humidity negative oxygen ion gas discharged from the upper end of the air guide tube 550 enters the upper part of the water container 520 after most of the water drops are removed by the dewatering plate 560, and finally discharged from the negative oxygen ion outlet 501.

[0048] In one embodiment, the air guide tube 550 is a metal tube or a plastic tube. Preferably, the plastic tube is a metal-plated plastic tube or a conductive plastic tube, and the metal tube is a stainless steel tube or a copper tube.

[0049] In one embodiment, the negative oxygen ion outlet 501 is disposed on the top cover 530 , and a water inlet is also disposed on the top cover 530 , and a water inlet plug 531 is disposed on the water inlet.

[0050] In one embodiment, the side wall of the blowing part housing 201 is formed with a receiving groove 230, and the air shock type negative oxygen ion generator 500 is arranged in the receiving groove 230, and the air outlet of the air pump 300 is connected to the air inlet pipe 540 of the air shock type negative oxygen ion generator 500 through the air outlet pipe or after passing through the air outlet silencer 320. The air outlet pipe is formed with a first joint on the side wall of the receiving groove 230, and the air shock type negative oxygen ion generator 500 is provided with a second joint. The first joint and the second joint are detachable sealed connection structures.

[0051] Adopting such a scheme of the present application, during assembly, the air pump cover 310 together with the air pump 300, the muffler, etc. are fixed to the blowing part 200, and then the air pump cover 310 together with the air pump 300, the muffler, etc. extend into the main body 100, and then the blowing part 200 is placed on the main body 100, and then fixedly connected by a fixing device (not shown in the figure). Such a structure saves space and is convenient for installation, disassembly and maintenance. Preferably, the drive motor 410 of the exhaust fan 400 is spatially located in the air pump cover 310, and the wind pumped by the exhaust fan 400 can better dissipate heat for the drive motor 410.

[0052] In one embodiment, the controller 210 is disposed inside the blowing portion housing 201 and is used to control the working states of the air pump 300 and the exhaust fan 400 .

[0053] Before working, water (preferably pure water or distilled water) is filled into the water container 520. The outer wall of the water container 520 is provided with high and low water level lines. When adding water, just add water to the high water level line. Since water will be consumed during use, when the water level drops to the low water level line, water needs to be added from the water filling port or the top cover 530 is removed to add water. During working, compressed air (oxygen) enters from the air inlet. The compressed air is transported to the air striking hole 513 along the air inlet pipe 540, and is ejected from the air striking hole 513 at a high speed. Since the gas has a very high flow rate in the air striking hole 513, a negative pressure is formed according to the principle of the Bernoulli equation, so that the water in the water container 520 is ejected from the outlet end of the air striking hole 513 along the water absorption hole 514 together with the compressed air at a high speed, and hits the water and the air striking plate 516, thereby generating high-concentration and high-humidity negative oxygen ion gas. The high-concentration and high-humidity negative oxygen ion gas rises along the air guide pipe 550, and continues to rub and hit in the air guide pipe 550. According to the principle of friction electrification, the compressed air is constantly in contact with and separated from the wall of the air guide pipe 550, and is negatively charged, further increasing the concentration of negative oxygen ions, which can reach more than 10 million / cubic centimeter. The high-concentration and high-humidity negative oxygen ion gas discharged from the upper end of the air guide pipe 550 enters the upper part of the water container 520 after most of the water droplets are removed by the dewatering plate 560, and is finally discharged from the negative oxygen ion outlet 501.

[0054] Although the present invention has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention based on the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection claimed by the present invention.
