Description

Technical Field

[0001] This invention relates to the field of fresh air purifier technology, specifically a portable outdoor fresh air purifier. Background Technology

[0002] A fresh air purifier is an air conditioning device that provides fresh air. It treats outdoor air through different levels of processes, such as dust removal, filtration, and disinfection, before delivering it indoors via a fan. When the fresh air purifier is working, outdoor air is first drawn into the air intake chamber, where it is filtered by air filtration components and then by a high-efficiency filter in the purification chamber before being delivered indoors.

[0003] Traditional air purifiers have a relatively complex internal structure. Because they are placed outdoors, they filter a large amount of dust during operation. This dust accumulates on the filter, eventually causing it to become clogged or affecting purification efficiency. Therefore, regular filter replacement is necessary. However, replacing filters in traditional air purifiers is very cumbersome, requiring disassembly of the outer casing to locate the filter element, making the replacement process relatively slow. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a portable outdoor fresh air purifier, which solves the problems mentioned in the background art.

Detailed Implementation

[0021] This invention provides a portable outdoor fresh air purifier, such as... Figure 1-8 As shown, the system includes a cabinet 1, with an air intake channel fixedly installed on the top of the cabinet 1 and an air inlet 13 fixedly installed on the bottom of the cabinet 1. Inside the cabinet 1, a pretreatment box 2, a filter box 3, and an air intake fan 4 are fixedly installed. The air intake fan 4 is installed at the bottom of the inner wall of the cabinet 1. The pretreatment box 2 is arranged above the air intake fan 4, and the filter box 3 is installed above the pretreatment box 2. The pretreatment box 2 is connected to the air inlet 13 through the air intake fan 4.

[0022] The pretreatment box 2 and the filter box 3 surround the inner wall of the cabinet 1 on the front and back sides, thus forming a buffer chamber 15. An air supply pipe is fixedly installed on the top of the cabinet 1, and the lower end of the air supply pipe extends into the cabinet 1 and connects with the top of the filter box 3.

[0023] Multiple rectangular frames 5 are slidably fitted inside the filter box 3. The multiple rectangular frames 5 are arranged sequentially from bottom to top. A reflector 52 is welded inside the rectangular frame 5. The reflector 52 is a magnetic strip with a reflective coating on its surface. A filter screen 51 is fixedly installed between the rectangular frame 5 and the reflector 52. A through hole 53 is opened at the center of the reflector 52. A large spring 54 is fixedly installed between two adjacent rectangular frames 5.

[0024] Ventilation openings are provided at the bottom of the filter box 3 and the top of the pretreatment box 2. The ventilation openings are connected to the buffer chamber 15. A through groove 31 is provided on the left side of the filter box 3. An ejection module is provided on the right side of the filter box 3. A drive module is provided at the top inside the filter box 3. The drive module drives the rectangular frame 5 to rise. A detection component is provided on the ejection module. The detection component is used to sense the weight of the rectangular frame 5.

[0025] Multiple filter layers 21 are installed inside the pretreatment chamber 2, and an electric heating wire 22 is fixedly installed inside the pretreatment chamber 2. The filter layers 21 are made of polypropylene fiber, activated carbon, and cotton fiber. The electric heating wire 22 heats the air. A negative ion purification module can also be installed inside the pretreatment chamber 2 to improve the purification effect. Since this is a conventional technical method, the specific structure and connection method are not described in detail.

[0026] The drive module includes an electromagnet module 6, a laser emitter 32, and a laser receiver 35. The electromagnet module 6 is fixedly installed on the top of the inner wall of the filter box 3. A vertical rod 61 is fixedly installed on the bottom of the electromagnet module 6, and the vertical rod 61 passes vertically through the through hole 53. A base is welded to the top of the inner wall of the filter box 3. The laser emitter 32 is fixedly installed on the left side of the base, and the laser receiver 35 is fixedly installed on the right side of the base.

[0027] Four sliding rods 33 are welded to the top of the inner wall of the filter box 3. The four sliding rods 33 correspond to the four corners of the rectangular frame 5 respectively. The sliding rods 33 vertically penetrate the rectangular frame 5. The upper half of the sliding rod 33 has a diameter of 1cm and the lower half of the sliding rod 33 has a diameter of 0.5cm.

[0028] The rectangular frame 5 has a sliding hole corresponding to the sliding rod 33. The diameter of the sliding hole is 0.5cm. When the uppermost rectangular frame 5 touches the upper half of the sliding rod 33, the light emitted by the laser emitter 32 is reflected and falls on the laser receiver 35.

[0029] The large spring 54 has a ring at its end, through which a screw passes, and the screw is screwed into the rectangular frame 5. This facilitates the installation and removal of the rectangular frame 5.

[0030] The ejector module includes an elastic membrane 7, liquid water 71, and an electric push rod 14. A water cavity is provided on the right side of the filter box 3. The elastic membrane 7 is fixedly installed at the opening of the water cavity. Liquid water 71 is poured into the water cavity, and the liquid water 71 occupies two-thirds of the internal volume of the water cavity. The electric push rod 14 is horizontally fixedly installed on the right side of the filter box 3. The movable end of the electric push rod 14 extends into the water cavity and is welded with a push plate.

[0031] The detection assembly includes a float 8, a pressure sensing unit 81, and a small spring 82. The float 8 floats in the water chamber. An extension plate 34 is welded to the right side of the filter box 3. The upper end of the float 8 passes vertically upward through the extension plate 34 and is fixedly installed with the pressure sensing unit 81. The small spring 82 is fixedly installed between the pressure sensing unit 81 and the extension plate 34.

[0032] Combined with appendix Figure 5 , 8 When the filtration reaches its limit, the weight of the rectangular frame 5 increases due to dust adhering to the filter screen 51. At this point, the magnetic force can no longer attract the rectangular frame 5, and the rectangular frame 5 falls, causing the laser receiver 35 to be unable to capture the light.

[0033] As the rectangular frame 5 falls and squeezes the elastic membrane 71, the liquid level in the water cavity rises, causing the float 8 to rise. The rise of the float 8 moves the pressure sensing unit 81 away from the extension plate 34, and the small spring 82 is pulled, thereby changing the value measured by the pressure sensing unit 81.

[0034] An ultraviolet lamp 16 is installed inside the buffer chamber 15. An angle bracket is hinged to the back of the cabinet 1, and the angle bracket is connected to the anti-vibration pad 12 by bolts. A cabinet door 11 is located on the left side of the cabinet 1. The cabinet 1 also has a control panel for operating various electronic components.

[0035] Installation steps: Open cabinet door 11, first assemble multiple rectangular frames 5 with large spring 54, then squeeze large spring 54, press rectangular frames 5 with your hands, after the rectangular frames 5 are stacked together close to each other, insert them into filter box 3 using through groove 31, at this time the rectangular frames 5 are in contact with elastic membrane 7.

[0036] The rectangular frame 5 moves to compress the liquid water 71 in the water chamber. When the rectangular frame 5 moves to its limit, the internal space of the water chamber can no longer shrink. At this time, the elastic membrane 7 is just flush with the inner wall of the filter box 3, and the perforation 53 of the rectangular frame 5 is just aligned with the vertical rod 61. At this time, the pressure sensing unit 81 measures the maximum value.

[0037] Next, the electromagnet module 6 is energized to generate a magnetic field. Under the action of the magnetic force, the rectangular frame 5 rises while the vertical rod 61 passes through the hole 53. Due to the weight of the rectangular frame 5 itself, the rectangular frames 5 move away from each other.

[0038] When the uppermost rectangular frame 5 reaches its highest point, the light emitted by the laser emitter 32 strikes the reflector 52 of the uppermost rectangular frame 5, and then falls onto the laser receiver 35 after reflection. The laser receiver 35 then transmits the information to the control panel outside the air purifier, informing the installer that the installation is complete.

[0039] Disassembly steps: When the rectangular frame 5 falls, the value measured by the pressure sensing unit 81 changes. The control panel receives the feedback information from the pressure sensing unit 81 and controls the change of the current direction entering the electromagnet module 6, thereby changing the magnetic field below the electromagnet module 6, so that the electromagnet module 6 generates a repulsive force on the rectangular frame 5, causing the rectangular frame 5 to be stacked back together.

[0040] When the value measured by the pressure sensing unit 81 reaches its maximum again, it indicates that the rectangular frames 5 are all stacked and compacted. Then, the electric push rod 14 extends to push one end of the rectangular frame 5 out of the through groove 31, making it easier for the worker to pull out the rectangular frame 5.

[0041] In summary, this portable outdoor air purifier comprises a cabinet 1, a pretreatment box 2, a filter box 3, and an intake fan 4 within the cabinet 1. The pretreatment box 2 performs preliminary air treatment, improving the purification effect. The filter box 3 contains multiple rectangular frames 5, each housing a filter screen 51. A large spring 54, an electromagnet module 6, and a reflector 52 work together to control the lifting and lowering of the rectangular frames 5, facilitating their installation and removal. This makes installation and removal more convenient and quick, further improving replacement efficiency.

[0042] Furthermore, the top of the inner wall of the filter box 3 is equipped with a laser emitter 33 and a laser receiver 35, which are used to sense the position of the rectangular frame 5. Together with the float 8, pressure sensing unit 81, small spring 82, elastic membrane 7, and liquid water 71, it can detect whether the filtration capacity has reached the required level, so that the filter components can be replaced in time to avoid excessive dust accumulation that would affect the filtration and purification effect.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
