Description

Technical Field

[0001] The present invention relates to the field of air purifiers, in particular to a household indoor air purifier. Background Art

[0002] When indoor air circulation is weak (especially during heating in winter and air conditioning in summer), the impact and harm caused by atmospheric pollution dust particles, odors and bacteria are more serious; in addition, there are a large number of synthetic chemical materials used for indoor and outdoor decoration, which produce harmful substances such as formaldehyde, nitrogen oxides, benzene (a type of VOC), TVOC (including many odor molecules), etc.

[0003] There are many types of air purifiers on the market, all with certain air purification functions. They generally use fans to circulate air, while utilizing the filtering effects of cotton filters and the adsorption effects of activated carbon to purify the air. While these devices are somewhat effective in adsorbing and treating particulate matter, they are often placed in corners of the house during use. They require a comprehensive circulation and gradual filtration of the indoor air to purify the air, which affects the indoor air purification efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a household indoor air purifier, by arranging a track on the indoor roof, so that the purification mechanism can move cyclically along the track, thereby improving the purification efficiency.

[0005] The purpose of the present invention is achieved through the following technical solutions: A household indoor air purifier includes a purification mechanism for purifying air and a track frame for being mounted on a roof. A slide is slid on the track frame, and a connecting arm is connected between the slide and the purification mechanism. The slide slides on the track frame to drive the purification mechanism to move indoors, and the height of the purification mechanism is controlled by the extension and retraction of the connecting arm.

[0006] The track frame comprises a fixing plate fixed to the roof, and an inverted T-shaped track is fixed to the lower end of the fixing plate.

An outer tube arm is axially slidably on the inner arm, and two inner cavity tubes are symmetrically provided on both sides of the outer tube arm. Spring I and clamping bead I are provided in the two inner cavity tubes, and the elastic force of spring I pushes the clamping bead I to press against the corresponding clamping hole I.

DETAILED DESCRIPTION

[0018] like Figure 1-10 As shown, a household indoor air purifier is described in detail: A household indoor air purifier includes a purification mechanism for purifying air and a track frame for being mounted on a roof. A slide is slid on the track frame, and a connecting arm is connected between the slide and the purification mechanism. The slide slides on the track frame to drive the purification mechanism to move indoors, and the height of the purification mechanism is controlled by the extension and retraction of the connecting arm.

[0019] The track frame is installed and laid on the indoor roof by bolts, and the slide is started to move along the track frame in a circular motion, so that the slide carries the purification mechanism through the connecting arm to move in a circular motion, thereby increasing its contact range with the air. Compared with placing the purification mechanism in a corner, the air purification efficiency is greatly improved. At the same time, the telescopic function of the connecting arm can be used to adjust the height of the purification mechanism and control the location of the purification mechanism. The purification mechanism can be moved first to the upper level of the room, then to the middle level, and finally to the lower level, or vice versa, thereby further improving the purification efficiency. Moreover, it can stay close to the location where pollution is generated, such as the newly renovated location, the smoking location, etc., thereby forming air purification adapted to special circumstances. The shape of the track frame can be circular, rectangular, or an irregular shape along the shape of the indoor house, thereby ensuring that the movement trajectory of the purification mechanism fully covers the indoor space and further improving the purification efficiency.

[0020] Further: The track frame includes a fixing plate 101 fixed to the roof, and an inverted T-shaped track 102 is fixed to the lower end of the fixing plate 101.

[0021] The slide includes a slide 201 , with step wheels 202 rotating at the four corners of the slide 201 . The four step wheels 202 roll symmetrically on both sides of the inverted T-shaped track 102 . A central axis 203 is vertically fixed to the center of the lower end of the slide 201 .

[0022] The fixing plate 101 is provided with small holes for fixing to the roof with bolts or screws; the track of the inverted T-shaped track 102 cooperates with the four step wheels 202 to form a limit for the slide, ensuring that the slide rolls along the inverted T-shaped track 102 through the step wheels 202 and preventing the slide from falling; Among them, a first motor is installed on the slide 201, which can drive one of the step wheels 202 to rotate, and through the friction between the step wheel 202 and the inverted T-shaped track 102, it can drive the slide 201 to move along the inverted T-shaped track 102.

[0023] Further: The connecting arm includes an arm base 301 that rotates on the central axis 203. Telescopic arms are rotated at both ends of the arm base 301. The lower ends of the two telescopic arms are connected to the purification mechanism.

[0024] The telescopic arm includes an inner arm 304 with one end rotating on the arm seat 301, and multiple clamping holes 305 are symmetrically provided on both sides of the inner arm 304. An outer tube arm 306 is axially slidably on the inner arm 304, and two inner cavity tubes 307 are symmetrically provided on both sides of the outer tube arm 306. Spring I 402 and clamping bead I 401 are provided in the two inner cavity tubes 307. The elastic force of spring I 402 pushes the clamping bead I 401 to press against the corresponding clamping hole I 305.

[0025] When controlling the extension and retraction of the telescopic arm, directly push and pull the purification mechanism to make the purification mechanism move closer to or away from the slide, which can drive the two outer tube arms 306 to slide on the two inner arms 304, and then drive the card bead I 401 to roll on the side of the inner arm 304. When the telescopic arm is adjusted to a suitable length, the card bead I 401 slides to the corresponding card hole I 305. Under the elastic force of the spring I 402, the card bead I 401 will slide out of the inner cavity tube 307 and press against the edge of the card hole I 305, thereby forming a card connection, forming a limited fixation between the inner arm 304 and the outer tube arm 306; and when subjected to strong pushing and pulling, the elastic force of the spring I 402 can be overcome, so that the card bead I 401 slides out of the card hole I 305, forming a rapid adjustment of the length of the telescopic arm.

[0026] Further: The purification mechanism includes a vertical tube shell 501, a containing chamber 503 is horizontally provided in the middle of the vertical tube shell 501, an adsorption component is provided in the containing chamber 503, an exhaust fan 508 is provided at the upper end of the vertical tube shell 501, a cover plate 504 is fixed to the upper end of the vertical tube shell 501, a breathable net is provided on the cover plate 504, a door-shaped plate 505 is fixed on the cover plate 504, and two horizontal shafts 308 are fixed to the lower ends of the two outer tube arms 306, and the two horizontal shafts 308 both penetrate and rotate on the door-shaped plate 505.

[0027] When purifying the air, the exhaust fan 508 is started to draw air from the lower end of the vertical pipe shell 501 into the vertical pipe shell 501, and after being filtered and adsorbed by the adsorption element, the air is purified. At the same time, the purified air is discharged through the air permeable net set on the cover plate 504.

[0028] Further: The two telescopic arms are arranged in parallel, and a worm gear 309 is fixed on one of the transverse shafts 308 . A worm 310 rotates on the door-shaped plate 505 , and the worm 310 is meshed and transmission-connected with the worm gear 309 .

[0029] By arranging the two telescopic arms in parallel, the two telescopic arms, the door-shaped plate 505 and the arm seat 301 form a parallelogram structure. When the worm 310 is rotated, the worm 310 will engage the transmission worm wheel 309 to rotate, and then drive its corresponding horizontal axis 308 to rotate relative to the door-shaped plate 505, thereby changing the angle between the worm wheel 309 and one side formed by the telescopic arm and the door-shaped plate 505, thereby changing the shape of the parallelogram. In this way, the height of the purification mechanism can be adjusted by rotating the two telescopic arms on the arm seat 301. In conjunction with the rotation of the arm seat 301 on the central axis 203, the purification mechanism can be extended to the side of the track frame, further increasing the contact area with the air. At the same time, the position of the purification mechanism can be adjusted to adapt to air purification in special circumstances.

[0030] Further: The adsorption member includes an inner sliding frame 506 , in which adsorption material is arranged, and baffles 507 are rotatably provided at both ends of the inner sliding frame 506 .

[0031] The inner sliding frame 506 is used to hold adsorption materials, which can be primary filters, HEPA filters, activated carbon filters, or composite filters. Replacement is completed by sliding the inner sliding frame 506 in the holding chamber 503. The two baffles 507 can be rotated to limit and fit at both ends of the holding chamber 503, thereby preventing the inner sliding frame 506 from falling.

[0032] An air hole net 502 is fixed to the lower end of the vertical pipe shell 501 to ensure ventilation while beautifying and protecting the lower end of the vertical pipe shell 501 .

[0033] Further: The central shaft 203 is evenly provided with a plurality of clamping holes II 204 circumferentially. A clamping column 302 is slidably passed through the arm seat 301 . A spring II 303 is provided between the clamping column 302 and the arm seat 301 to make the clamping column 302 press against the corresponding clamping hole II 204 .

[0034] The elastic force of spring II 303 pushes the end of the clamping column 302 against the clamping column 302, forming a clamping limit, preventing the arm seat 301 from rotating freely on the central axis 203, and ensuring the stability of the purification mechanism when it is in a special position. When twisted vigorously, the clamping column 302 can overcome the elastic force of spring II 303 and slide out of the clamping hole II 204, so that the arm seat 301 can rotate on the central axis 203, ensuring the rapid adjustment of the position of the purification mechanism.
