Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, specifically to an exhaust component for a nitrous oxide purifier. Background Technology

[0002] Air purifiers, also known as air cleaners, air fresheners, or air purifiers, are products that can adsorb, decompose, or transform various air pollutants, generally including PM2.5, dust, formaldehyde, and other pollutants, effectively improving air cleanliness.

[0003] An investigation revealed a Chinese utility model patent (publication number: CN214368472U) disclosing an exhaust component in a high-purity nitrous oxide purifier. The general description includes a purifier housing, with symmetrical housing support columns fixed to the lower end of the housing. The outer wall of the housing has air guide plate mounting holes, and the outer wall also has a mounting column fixing seat. The mounting column fixing seat has threaded holes on its outer wall, and a fixing column is installed within these threaded holes. One end of each fixing column has a top block, and the other end has an exhaust pipe fixing seat. An exhaust pipe is fixed to the outer wall of the exhaust pipe fixing seat, and an air guide plate is installed inside the air guide plate mounting holes. This high-purity nitrous oxide purifier has an independent sealing component inside, allowing it to automatically seal after the exhaust pipe is disassembled, preventing outside air from entering the purifier and improving its stability.

[0004] Although the above technical solution can use the top block and air guide plate at one end of the mounting column, together with the sealing component, to use the airflow impact force to impact the sealing plate when the purifier exhausts, causing the sealing plate to contract through the spring at the end, allowing the exhaust gas to be discharged through the pushed-open gap, this component will experience elastic fatigue due to the material properties of the spring after long-term repeated expansion and contraction. This will reduce the elastic performance of the spring, making it difficult for the sealing component in the exhaust component to maintain the sealing effect after long-term use.

[0005] Therefore, this utility model provides an exhaust component for a nitrous oxide purifier to solve the above-mentioned problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an exhaust component for a nitrous oxide purifier, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An exhaust assembly for a nitrous oxide purifier includes a housing, an air inlet plate fixedly connected to the top of the housing, and an exhaust assembly for exhaust on the side wall of the housing.

[0009] The exhaust assembly includes an inner exhaust pipe fixedly connected to the side wall of the housing. A one-way valve for preventing exhaust gas backflow is fixedly connected to the inner wall of the inner exhaust pipe. A sealing strip is fixedly connected to the outer wall of the one-way valve. A retraction spring for valve plate reset is fixedly connected to the end of the one-way valve. An outer exhaust pipe is sleeved on the outer wall of the inner exhaust pipe. A slide rod is fixedly connected to the inner wall of the outer exhaust pipe. A spring is fixedly connected to the inner wall of the outer exhaust pipe outside the slide rod. A slide seat is slidably connected to the outer wall of the slide rod, and the end of the slide seat is fixedly connected to the end of the spring. An end plate is fixedly connected to the end of the slide seat. A stop plate is provided on the outer wall of the end plate, and the stop plate is slidably connected to the inner wall of the inner exhaust pipe. An air supply assembly is provided on the outer wall of the outer exhaust pipe.

[0010] A further improvement of the present invention is that the air supply assembly includes a base fixedly connected to the exhaust pipe, a micro fan for air supply is fixedly connected to the top of the base, a slot is opened at the top of the base, a straight rod is rotatably connected to the outer wall of the slot, the upper end of the straight rod is connected to the start switch of the micro fan, a connecting block is fixedly connected to the bottom end of the straight rod, and the connecting block is fixedly connected to the outer wall of the stop plate.

[0011] A further improvement of this utility model is that: the outer wall of the exhaust pipe is provided with an outlet for discharging exhaust gas, and the inner wall of the outlet is fixedly connected with a filter screen to prevent dust from entering the interior of the exhaust pipe.

[0012] A further improvement of the present invention is that: the outer wall of the stop plate is provided with a snap-fit ​​assembly, the snap-fit ​​assembly includes a plurality of snap-fit ​​rods slidably connected to the end plate and the inside of the stop plate, the ends of the snap-fit ​​rods are symmetrically provided with snap-fit ​​grooves, the inner wall of the snap-fit ​​groove is telescopically connected with a telescopic rod, the inner wall of the snap-fit ​​groove is rotatably connected with an inclined rod, and the inner wall of the inclined rod is fixedly connected to the top end of the telescopic rod.

[0013] A further improvement of this utility model is that a turntable is fixedly connected to the bottom of the box, and a filter element for purifying gas is rotatably connected to the top of the turntable.

[0014] A further improvement of this utility model is that: a sliding wheel is fixedly connected to the bottom of the box, and a foot pedal is fixedly connected to the upper end of the sliding wheel.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the exhaust component installed inside the housing can discharge the filtered gas. When the exhaust gas passes through the one-way valve inside the exhaust pipe, it cannot flow back into the purifier after being discharged. Instead, the airflow pushes the stop plate to drive the slide block to slide on the slide rod, and the exhaust gas is discharged through the open gap. The two layers of anti-gas backflow components inside the exhaust pipe and the exhaust pipe can not only ensure that after the exhaust gas is discharged, external air is prevented from entering the purifier and affecting the purification efficiency, but also extend the service life of the purifier to a certain extent.

[0025] Reference Figure 1-Figure 5 This utility model provides two technical solutions:

[0026] Example 1:

[0027] A nitrous oxide purifier exhaust assembly includes a housing 1, an air inlet plate 101 fixedly connected to the top of the housing 1, and an exhaust assembly 2 for exhausting the air from the side wall of the housing 1.

[0028] The exhaust assembly 2 includes an inner exhaust pipe 201 fixedly connected to the side wall of the housing 1. A one-way valve 202 for preventing backflow of exhaust gas is fixedly connected to the inner wall of the inner exhaust pipe 201. A sealing strip 203 is fixedly connected to the outer wall of the one-way valve 202. A retraction spring 204 for valve plate reset is fixedly connected to the end of the one-way valve 202. An outer exhaust pipe 205 is sleeved on the outer wall of the inner exhaust pipe 201. A slide rod 206 is fixedly connected to the inner wall of the outer exhaust pipe 205. A spring 207 is fixedly connected to the inner wall of the outer exhaust pipe 205 outside the slide rod 206. A slide seat 208 is slidably connected to the outer wall of the slide rod 206, and the end of the slide seat 208 is fixedly connected to the end of the spring 207. An end plate 209 is fixedly connected to the end of the slide seat 208. A stop plate 210 is provided on the outer wall of the end plate 209, and the stop plate 210 is slidably connected to the inner wall of the inner exhaust pipe 201. An air supply assembly 3 is provided on the outer wall of the outer exhaust pipe 205.

[0029] The air supply assembly 3 includes a base 301 fixedly connected to the exhaust pipe 205. A miniature fan 302 for air supply is fixedly connected to the top of the base 301. A slot 303 is opened at the top of the base 301. A straight rod 304 is rotatably connected to the outer wall of the slot 303. The upper end of the straight rod 304 is connected to the start switch of the miniature fan 302. A connecting block 305 is fixedly connected to the lower end of the straight rod 304. The connecting block 305 is fixedly connected to the outer wall of the stop plate 210.

[0030] A turntable 102 is fixedly connected to the bottom of the box 1, and a filter element 103 for purifying gas is rotatably connected to the top of the turntable 102.

[0031] A sliding wheel 104 is fixedly connected to the bottom of the box body 1, and a foot pedal 105 is fixedly connected to the top of the sliding wheel 104.

[0032] The outer wall of the exhaust pipe 205 is provided with an outlet 211 for discharging exhaust gas, and a filter screen 212 is fixedly connected to the inner wall of the outlet 211 to prevent dust from entering the interior of the exhaust pipe 205.

[0033] Specifically, the air inlet plate 101 at the top of the housing 1 allows external air requiring purification to enter the housing and be purified by the filter element 103 rotating on the turntable 102 inside the housing. The sliding wheels 104 at the bottom of the housing 1 facilitate its sliding operation. The exhaust assembly 2 outside the housing 1 discharges the purified exhaust gas. After passing through the inner exhaust pipe 201, the exhaust gas passes through the outer exhaust pipe 205 and is then discharged from the outlet 211. The filter screen 212 inside the outlet 211 prevents dust from entering the housing 1 and causing pollution. The one-way valve 202 inside the inner exhaust pipe 201 prevents the exhaust gas from flowing back into the housing during the discharge process. The exhaust gas discharged by the purifier blows the stop plate 210. The slide block 208 behind the end plate 209 slides on the slide rod 206, allowing exhaust gas to be discharged through the gap. When the stop plate 210 moves, it will drive the straight rod 304 on the connecting block 305 to rotate. Then, the upper end of the straight rod 304 will move with the start switch of the micro fan 302, thereby turning on the micro fan 302. The airflow of the micro fan 302 will further discharge the exhaust gas from the exhaust pipe 205. After the exhaust is completed, the stop plate 210 will be reset by the spring 207, which will drive the straight rod 304 to reset, thereby turning off the micro fan 302. The one-way valve 202 and the stop plate 210 inside the component can achieve a double sealing effect, which can not only facilitate the discharge of exhaust gas, but also extend the service life of the purifier to a certain extent.

[0034] Example 2:

[0035] Based on Example 1:

[0036] The outer wall of the stop plate 210 is provided with a snap-fit ​​assembly 4. The snap-fit ​​assembly 4 includes multiple snap-fit ​​rods 401 that are slidably connected to the end plate 209 and the inside of the stop plate 210. The ends of the snap-fit ​​rods 401 are symmetrically provided with snap-fit ​​grooves 402. The inner wall of the snap-fit ​​grooves 402 is telescopically connected with telescopic rods 403. The inner wall of the snap-fit ​​grooves 402 is rotatably connected with inclined rods 404, and the inner wall of the inclined rods 404 is fixedly connected to the top end of the telescopic rods 403.

[0037] Specifically, the snap-fit ​​assembly 4 on the outer wall of the stop plate 210 allows for quick connection and disconnection between the stop plate 210 and the end plate 209, facilitating replacement of the stop plate 210 during use. After the snap-fit ​​rod 401 is inserted, the spring-loaded telescopic rod 403 supports the inclined rod 404, enabling a quick and tight connection between the stop plate 210 and the end plate 209.
