Description

Technical Field

[0001] The invention relates to the technical field of air purifiers, in particular to an air purifier with intelligent humidity control. Background Art

[0002] With the improvement of modern living standards, people have higher and higher requirements for indoor air quality, especially in dusty and dry environments. Although existing air purifiers have alleviated the problem of indoor air pollution to a certain extent, their technical status still has many shortcomings, especially in dusty environments, where filters are easily clogged, difficult to clean, and have high replacement costs.

[0003] Existing air purifiers mainly rely on filter technology to remove pollutants from the air, including large particles such as dust, hair, pollen, and some tiny particles. However, in a dusty environment, the filter tends to quickly accumulate a lot of dust, resulting in a decrease in filtration efficiency and even clogging the filter, affecting the normal use of the air purifier. In addition, the filters of existing air purifiers are mostly disposable. When the filter is clogged or reaches the end of its service life, users need to frequently replace the filter, which increases the cost of use.

[0004] Therefore, it is necessary to provide an air purifier with intelligent humidity control, optimize filter structure and materials, and solve the problems of easy clogging, difficult cleaning, high replacement cost, and low intelligence. By adopting a detachable and easy-to-clean filter design, introducing humidity sensors and intelligent control systems, etc., real-time monitoring and intelligent adjustment of indoor environmental humidity and air quality are achieved.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] The present invention realizes effective removal of dust and tiny particles in the air through multiple filtering mechanisms. First, the external air enters through the air intake gap and is initially captured by the dust removal strips on the first, second and third spacer rings. These dust removal strips are made of easy-to-clean materials and have a fine structure, which significantly enhances the dust adsorption capacity. Subsequently, the air is further filtered through the filter screen to remove tiny particles, ensuring the freshness and cleanliness of the exhaust air. This significantly improves the air purification efficiency and provides users with a healthier indoor environment.

[0034] The device of the present invention has a built-in humidity sensor that can monitor the ambient humidity in real time and automatically adjust the working state of the atomizing device according to a preset value. When the indoor humidity is lower than the set value, the atomizing device automatically starts, atomizes the water in the water tank and sends it into the air outlet through a hollow shaft to mix with the purified air, thereby increasing the air humidity. This intelligent humidity adjustment function not only improves the user's comfort, but also helps maintain the humidity balance of the indoor environment and reduces the discomfort caused by dry air.

[0035] The dust removal rubber strips in the present invention are made of easy-to-clean materials, and the reverse-rotating turntable drives the dust removal rubber strips to rub and collide, which can effectively remove dust attached to the rubber strips and avoid dust accumulation and secondary pollution inside the equipment. And the air valve assembly can flexibly adjust the air flow path through the independent control and coordination of the first valve plate and the second valve plate. In normal purification mode, the first valve plate is opened and the second valve plate is closed to ensure that the air flows along the established path and is discharged after sufficient dust removal and filtration. In dust removal and cleaning mode, the first valve plate is closed and the second valve plate is opened, allowing the reverse airflow to be discharged directly through the second valve plate, reducing the resistance of air flow and improving the cleaning effect.

DETAILED DESCRIPTION

[0042] See also Figure 1-Figure 5 In an embodiment of the present invention, an air purifier with intelligent humidity control includes an outer cylinder 1, an inner cylinder 2 is fixed at the lower part of the outer cylinder 1, and a first spacer ring 3, a second spacer ring 4, and a third spacer ring 5 are sequentially distributed in the gap between the inner cylinder 2 and the outer cylinder 1 from the inside to the outside;

[0043] The first spacer ring 3 and the third spacer ring 5 are fixedly connected to the bottom of the outer tube 1, and the second spacer ring 4 is connected to the top of the inner tube 2;

[0044] There is an air intake gap at the bottom between the inner tube 2 and the first spacer ring 3 for the initial intake of external air;

[0045] The inner and outer surfaces of the second spacer ring 4 are both provided with dust removal rubber strips, and the first spacer ring 3 and the third spacer ring 5 are also provided with dust removal rubber strips on one side close to the second spacer ring 4 to capture dust in the air;

[0046] At a position above the third spacer ring 5, a wind valve assembly 6 is provided between the second spacer ring 4 and the outer tube 1 for adjusting the air flow direction;

[0047] A filter screen 7 is disposed above the air valve assembly 6 to further filter tiny particles in the air;

[0048] A turntable 8 is rotatably provided at the upper end of the inner cylinder 2, a fan blade 11 is provided above the turntable 8, and a motor 10 for driving the turntable 8 to rotate is provided inside the inner cylinder 2;

[0049] An air outlet tube 9 aligned with the fan blades 11 is provided at the upper end of the outer tube 1 .

[0050] In this embodiment, the filter screen 7 is designed to be detachable, so that the user can clean or replace it regularly to ensure the purification effect.

[0051] In this embodiment, the dust removal rubber strip is made of easy-to-clean material and has a micro-concave-convex structure on the surface to enhance the dust adsorption capacity.

[0052] When the motor 10 is working, it drives the turntable 8 and the fan blades 11 to rotate, generating negative pressure, causing air to enter from the air intake gap, and then be discharged from the air outlet 9 after dust removal and filtration.

[0053] In this embodiment, a water tank 12 is connected to the bottom of the inner cylinder 2, and the water tank 12 is detachable;

[0054] The inner cylinder 2 is provided with an atomizing device 13, and the pipeline of the atomizing device 13 extends into the water tank 12;

[0055] A central shaft 14 that passes through the fan blades 11 and the motor 10 from top to bottom is fixed in the middle of the turntable 8, and the central shaft 14 is a hollow shaft.

[0056] That is to say, the water in the water tank 12 can be atomized by the atomizing device 13. When the fan blades 11 rotate, due to the upward airflow in the air outlet pipe 9, the water mist in the inner tube 2 can enter the air outlet pipe 9 through the central axis 14, and then be discharged with the purified air, thereby increasing the humidity.

[0057] In this embodiment, a humidity sensor is also included, which is arranged at the air intake gap and is used to detect the ambient humidity. The working state of the atomization device 13 is automatically adjusted according to the detection result to achieve intelligent control of the humidity.

[0058] See also Figure 3 In this embodiment, a rotating ring 41 is fixed to the upper end of the second spacer ring 4, and the rotating ring 41 is rotatably sleeved on the outer wall of the inner tube 2, and a circle of ratchet teeth 42 is provided in the rotating ring 41;

[0059] A plurality of ratchet claws 43 are rotatably disposed at the bottom of the rotating disk 8 , and the ratchet claws 43 are in contact with the ratchet teeth 42 .

[0060] When the motor 10 drives the turntable 8 to rotate in the forward direction, the turntable 8 will not drive the rotating ring 41 to rotate;

[0061] When the motor 10 drives the turntable 8 to rotate in the reverse direction, the turntable 8 drives the rotating ring 41 to rotate, and causes the second spacer ring 4 to rotate, so that the dust removal strips rub and collide with each other to clean the dust in the dust removal strips. At the same time, the reverse airflow generated by the fan blades 11 during reverse rotation can further discharge the cleaned dust from the air intake gap, avoiding dust accumulation and secondary pollution inside the equipment.

[0062] In this embodiment, the air valve assembly 6 includes an annular bracket 61, the bracket 61 is fixed to the inner wall of the outer tube 1, and a circle of second valve disc 63 and first valve disc 62 are respectively distributed inside and outside the bracket 61, and the first valve disc 62 and the second valve disc 63 are both rotatably connected to the bracket 61;

[0063] The first valve plate 62 is distributed between the third spacer ring 5 and the outer tube 1;

[0064] The second valve plate 63 is distributed between the third spacer ring 5 and the second spacer ring 4;

[0065] The filter screen 7 is distributed between the first valve plate 62 and the second valve plate 63 .

[0066] Through the independent control and coordination of the first valve plate 62 and the second valve plate 63, the air valve assembly 6 can flexibly adjust the air flow path. In the normal purification mode, the first valve plate 62 is opened and the second valve plate 63 is closed, ensuring that the external air is discharged from the air outlet 9 after being dusted by the dust removal rubber strip and filtered by the filter 7, thereby ensuring the air purification quality; while in the dust removal cleaning mode, the first valve plate 62 is closed and the second valve plate 63 is opened, so that the reverse airflow generated by the fan blades 11 can be discharged directly through the second valve plate 63. This process does not need to pass through the filter 7, avoiding unnecessary air flow distance, reducing air flow resistance, and improving the cleaning effect.

[0067] In this embodiment, the bracket 61 includes a first valve disc 62 and a second valve disc 63 as a pair, and multiple pairs of brackets 61 are evenly distributed around the bracket 61. The centers of the same pair of first valve disc 62 and second valve disc 63 are fixedly connected together through a rotating shaft 64, and the rotating shaft 64 is rotatably connected to the bracket 61.

[0068] The same pair of first valve plates 62 and one second valve plate 63 are perpendicular to each other.

[0069] That is to say, when the first valve disc 62 is opened, the second valve disc 63 will be closed. Similarly, when the first valve disc 62 is closed, the second valve disc 63 will be opened.

[0070] In this embodiment, each of the rotating shafts 64 penetrates the outer wall of the outer cylinder 1, and a rotating rod 65 is fixed to one end of the rotating shaft 64 on the outer wall of the outer cylinder 1, and a latch 66 is fixed to the rotating rod 65;

[0071] The outer wall of the outer tube 1 is slidably sleeved with a sliding ring 67 , and the inner wall of the sliding ring 67 is provided with a sliding groove 68 , and each of the latch pins 66 is slidably embedded in the sliding groove 68 .

[0072] That is to say, when the slip ring 67 slides up and down, since the latch 66 is embedded in the slide groove 68, it will drive each rotating shaft 64 to rotate synchronously, thereby controlling a first valve plate 62 and a second valve plate 63 to open or close synchronously.

[0073] In this embodiment, a plurality of guide blocks 69 are fixed to the outer wall of the slip ring 67, an electromagnet 611 is fixed to the outer wall of the outer cylinder 1 above each guide block 69, and a spring 610 is fixed between the guide block 69 and the electromagnet 611;

[0074] The guide block 69 is made of magnetic conductive material.

[0075] That is to say, when the electromagnet 611 is powered off, the slip ring 67 slides downward under the action of the spring 610, and when the electromagnet 611 is powered on, the guide block 69 is adsorbed by the electromagnet 611 and slides upward, thereby controlling the slip ring 67 to slide up and down, and further controlling the opening or closing of a first valve plate 62 and a second valve plate 63.

[0076] The specific implementation includes:

[0077] Air purification process: the motor 10 drives the fan blades 11 to rotate, and the external air enters the air purifier through the air intake gap between the inner cylinder 2 and the first spacer ring 3;

[0078] When the air passes through the gaps between the first spacer ring 3, the second spacer ring 4 and the third spacer ring 5, the dust removal rubber strip captures dust particles in the air;

[0079] The air that has been initially dusted by the dust removal strips continues to rise and passes through the filter 7 to further filter out tiny particles;

[0080] When humidification is required, the atomizing device 13 atomizes the water in the water tank 12, and the water mist enters the air outlet cylinder 9 through the central axis 14 and mixes with the purified air to increase the air humidity;

[0081] The air that has been dusted, filtered and humidified is discharged through the air outlet 9 to provide fresh and moist air for the room.

[0082] Dust removal strip cleaning: Control the electromagnet 611 to be energized, so that the slip ring 67 slides upward, driving the first valve plate 62 to close and the second valve plate 63 to open, allowing the reverse airflow to be discharged directly through the second valve plate 63;

[0083] The motor 10 drives the turntable 8 to rotate in the opposite direction, driving the rotating ring 41 and the second spacer ring 4 to rotate, so that the dust removal strips rub and collide with each other to clean the dust. At the same time, the reverse rotating fan blades 11 generate reverse airflow to discharge the cleaned dust from the air intake gap.

[0084] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
