Abstract

The application discloses an indoor air purifier using activated carbon and relates to the technical field of indoor air purification. The indoor air purifier comprises a shell, and a control panel is arranged at the top end of the shell. The indoor air purifier has the advantages that the opening degree of a transition cavity can be automatically adjusted according to the rotating speed of a first paddle, that is, the use amount of an activated carbon filter core is automatically adjusted according to the operating power. When the indoor air purifier is operated at low power, the air sucked by the first paddle can be concentrated in the grooves on the outer side, so that the air is prevented from escaping into the shell, thereby enabling the indoor air to be concentrated and filtered, ensuring the permeation efficiency of the activated carbon filter core and further ensuring the purification efficiency, enabling the air speed of an air outlet to be stable, and enabling the indoor air purifier to be operated at multiple powers, so that the device can be adapted to multiple scenes and multiple requirements.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of indoor air purification, in particular to an indoor air purifier using activated carbon. BACKGROUND

[0002] The activated carbon air purifier mainly removes pollutants in the air through physical adsorption, and its working process can be divided into air suction, activated carbon adsorption, auxiliary purification, air exhaust and filter core maintenance. The period of filter core maintenance is usually 3-6 months. After the pores of activated carbon are filled, the adsorption capacity will decrease, and there will be a backflow of odor. The existing pull-out type air purifier, such as the Xingfeng T2 Pro, adopts a pull-out replacement structure design, which has advantages in maintenance convenience and space utilization.

[0003] However, the inhaled air needs to penetrate layer by layer. When running at high power, the amount of inhaled air is large, and the penetration speed is fast, so that the air outlet rate of the air outlet is stable and efficient. When running at low power, the amount of inhaled air is small, and the air escapes and penetrates layer by layer after entering the shell. At this time, the purification efficiency is low, and the air speed of the air outlet is unstable. If a single power is used, the use of the device is limited and cannot adapt to multiple scenes and multiple requirements. At the same time, the use of low power causes all activated carbon filter cores to be used, but the escaped air cannot uniformly enter all activated carbon filter cores, so that the saturation of the activated carbon filter cores is not the same, and the saturated activated carbon filter cores cannot be distinguished, thereby requiring uniform replacement, which causes unnecessary waste.

[0004] Through retrieval, Chinese patent application CN102225214A discloses an indoor ceiling type air purifier, which has low cost, wide application range and significant effect, but cannot solve the above problems. At the same time, the sealing property of the pull-out type activated carbon filter core cannot be adjusted according to the purification efficiency when purifying air. When purifying at high power, the air pressure in the shell increases, so that the drawer and the shell are easy to produce gaps, thereby causing air to escape and affecting air purification efficiency. The escaped air also causes energy waste. When replacing the activated carbon filter core, the larger sealing property blocks the taking of the activated carbon filter core. When air is inhaled, the larger particles blocked by the filter screen cannot be removed from the filter screen, affecting the air inlet efficiency and requiring manual cleaning. SUMMARY

[0031] Please refer to Figures 2-4 , transition cavity 8 is communicated with placing cavity 4, and the communication part of transition cavity 8 and placing cavity 4 corresponds to filter hole 13 one by one, the end of inner cavity 9 extends to the outside of shell 1, fixed sleeve 24 is fixedly connected to the side wall of transition cavity 8, sliding block 26 is slidably connected to the top surface of transition cavity 8, sliding plate 27 is slidably connected to the top surface of transition cavity 8, sliding plate 27 and multi-stage telescopic plate 28 are both slidably connected to the side wall of transition cavity 8, and sealing strips are arranged between sliding plate 27, multi-stage telescopic plate 28 and transition cavity 8, and fixed plate 29 is fixedly connected to transition cavity 8.

[0032] Please refer to Figure 1 and Figure 2The drawer 10 is provided with multiple recesses 12, and the recesses 12 of the multiple drawers 10 are located on the same vertical line. The piston rod 25 gradually seals the top end of the transition cavity 8 through the sliding block 26, the sliding plate 27 and the multi-stage telescopic plate 28.

[0033] Please refer to Figure 4 and Figure 7 The first paddle 18 is sleeved with the rotating shaft 15, the first driving roller 19 is sleeved with the rotating shaft 15, the first driven roller 21 and the second paddle 22 are rotationally connected with the side wall of the inner cavity 9, and the first track 20 is slidingly sleeved with the shell 1.

[0034] Please refer to Figure 3 and Figure 6 The connecting pipe 23 is fixedly sleeved with the shell 1, and the communication end of the connecting pipe 23 with the fixed sleeve 24 is located between the piston rod 25 and the sliding block 26.

[0035] Specifically, in the process of purifying indoor air, the power supply system is controlled by the control panel 2, and the fixed coil 16 on the rotating shaft 15 is powered to generate an induced magnetic field. At this time, the Hall sensor identifies the position of the magnetic rotor 17 and feeds back a signal to the control panel 2. The control panel 2 controls the on-off of the MOSFET tube in the inverter bridge according to the position signal, continuously circulates, forms a rotating magnetic field, and drives the rotating shaft 15 to rotate. or The abrupt change in electrical angle attracts the magnetic rotor 17 to rotate continuously, thereby causing the first blade 18 to rotate continuously. This causes the first blade 18 to draw in indoor air, which then enters the air intake duct 7 and subsequently the transition chamber 8. Simultaneously, the first driving roller 19 on the first blade 18 drives the first track 20 to rotate, causing the first driven roller 21 on the first track 20 to rotate. This, in turn, causes the first driven roller 21 to drive the second blade 22 to rotate, allowing the second blade 22 to draw in indoor air. Air, which then enters the connecting pipe 23 from the inner cavity 9, is guided by the connecting pipe 23 into the fixed sleeve 24. A portion of the air entering the fixed sleeve 24 overflows from its end. As the first blade 18 accelerates its rotation, the second blade 22, according to the above principle, accelerates its rotation, increasing the amount of air in the fixed sleeve 24. When the increase exceeds the overflow, the air pressure at the end of the fixed sleeve 24 rises, thereby pushing the piston rod 25 to move, causing the piston rod 25 to retract into the fixed sleeve 24, thus... The slider 26 on the piston rod 25 drives the slide plate 27 to move horizontally, causing the slide plate 27 to gradually open the top of the transition chamber 8. This allows air in the transition chamber 8 to pass through the corresponding through hole 5 and enter the groove 12 through the corresponding filter hole 13. The activated carbon filter in the groove 12 filters the indoor air and finally discharges it through the air outlet 3, completing the purification of the indoor air. In summary, the opening degree of the transition chamber 8 can be automatically adjusted according to the rotation speed of the first blade 18, that is, the amount of activated carbon filter used can be automatically adjusted according to the operating power. When the indoor air purifier is running at low power, the air drawn in by the first blade 18 can be concentrated in the outer groove 12, preventing air from escaping into the housing 1. This allows the indoor air to be filtered in a concentrated manner, ensuring the permeability efficiency of the activated carbon filter and thus ensuring the purification efficiency. This makes the air speed at the air outlet 3 stable. At the same time, the indoor air purifier can operate at multiple power levels, making the device adaptable to various scenarios and requirements. Furthermore, the activated carbon filter can be used sequentially from the outside to the inside, so the saturation of the activated carbon filter can be judged according to the usage, eliminating the need for uniform replacement and saving costs.

[0036] Example 2

[0037] Please see Figures 3-5 The present invention provides a technical solution: an indoor air purifier using activated carbon, wherein an air passage 30 is provided in the side wall of the housing 1, one end of the air passage 30 is connected to the inner cavity 9, and the other end of the air passage 30 is connected to the annular groove 6, and a sealing ring 11 is slidably sleeved in the annular groove 6, and the sealing ring 11 is fixedly connected to the drawer 10.

[0038] Please see Figure 4 , Figure 8 and Figure 9The second track 33 is sleeved with the shell 1, the transmission shaft 35 is rotatably sleeved with the filter screen 31, the sleeve ring 40 is sleeved with the connecting rod 36, and the sleeve ring 40 and the connecting rod 36 are provided with a reset spring between end faces, and the scraping ring 41 is sleeved with the rubber roller 37.

[0039] Specifically, in the process of the second paddle 22 sucking air, the air in the air duct 30 is drawn, and the air duct 30 is communicated with the ring groove 6, so that the second paddle 22 indirectly sucks the air in the ring groove 6, and the ring groove 6 and the sealing ring 11 gradually form a vacuum, so that the atmospheric pressure pushes the side wall of the drawer 10 to maintain the sealing of the drawer 10 and the shell 1. According to the above principle, when the operating power of the device is increased, the rotating speed of the second paddle 22 is increased, so that the air flow loss efficiency of the ring groove 6 is increased, and the sealing between the drawer 10 and the shell 1 is indirectly increased. On the contrary, indoor air can flow back to the ring groove 6, which indirectly reduces the sealing between the drawer 10 and the shell 1, so that the sealing of the drawer 10 can be adjusted according to the purification efficiency, and the air can be conveniently replaced while avoiding air leakage.

[0040] Embodiment 3

[0041] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 8 and Figure 9 , the present application provides a technical solution: an indoor air purifier using activated carbon, the end of the air inlet channel 7 is fixedly connected with the filter screen 31, the end face of the second paddle 22 is fixedly connected with the second driving roller 32, the outer surface of the second driving roller 32 is sleeved with one end of the second track 33, the other end of the second track 33 is sleeved with the second driven roller 34, one end of the transmission shaft 35 is fixedly connected with the central axis of the second driven roller 34, the other end of the transmission shaft 35 is fixedly connected with the connecting rod 36, the outer surface of the connecting rod 36 is rotatably sleeved with the rubber roller 37, the outer surface of the rubber roller 37 is provided with a spiral groove 38, the spiral groove 38 is slidably connected with the slide rod 39, one end of the slide rod 39 is fixedly connected with the sleeve ring 40, the other end of the slide rod 39 is fixedly connected with the scraping ring 41, one end of the clamping block 42 is rotatably connected with the side wall of the shell 1, the other end of the clamping block 42 is in contact with the blocking frame 43.

[0042] Please refer to Figure 1 and Figure 8 , the rubber roller 37 is slidably connected with the end face of the filter screen 31, the spiral groove 38 is arranged in a single ring and communicated at the head and tail, the blocking frame 43 is fixedly connected with the shell 1, and the clamping block 42 is located in the movement track of the drawer 10.

[0043] Specifically, in the process of rotating the second paddle 22, the second paddle 22 drives the second track 33 to rotate through the second driving roller 32, so that the second driven roller 34 on the second track 33 drives the transmission shaft 35 to rotate, so that the connecting rod 36 on the transmission shaft 35 drives the rubber rotating roller 37 to revolve, so that the rubber rotating roller 37 cleans the surface of the filter screen 31, and when the rubber rotating roller 37 revolves, due to the friction between the rubber rotating roller 37 and the filter screen 31, the rubber rotating roller 37 revolves while rotating, when the rubber rotating roller 37 rotates, the spiral groove 38 on the rubber rotating roller 37 extrudes the side wall of the sliding rod 39, so that the spiral groove 38 pushes the sliding rod 39, the sleeve ring 40 and the scraping ring 41 to translate, so that the scraping ring 41 cleans the surface of the rubber rotating roller 37, when the sliding rod 39 moves to the other end of the spiral groove 38, due to the connection of the spiral groove 38, the sliding rod 39 and the sleeve ring 40 are reset under the rebound of the reset spring, so that the scraping ring 41 is reset, and the above operation is repeated, so that the filter screen 31 and the rubber rotating roller 37 can be continuously cleaned, without manual cleaning of the inlet of the air inlet channel 7, and the air inlet efficiency of the air inlet channel 7 is ensured.

[0044] The working principle and use process of the present application: in the process of indoor air purification, the power supply system is controlled by the control panel 2, and the fixed coil 16 on the rotating shaft 15 is powered, so that the fixed coil 16 generates an induced magnetic field, at this time the Hall sensor identifies the position of the magnetic rotor 17, and feeds back a signal to the control panel 2, the control panel 2 controls the on-off of the MOSFET tube in the inverter bridge according to the position signal, continuously circulates, forms a rotating magnetic field, and drives the magnetic rotor 17 to rotate, so that the magnetic rotor 17 drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the fan 14 to rotate, so that the fan 14 rotates and drives the air inlet channel 7 to rotate, so that the air inlet channel 7 rotates and drives the filter screen 31 to rotate, so that the filter screen 31 rotates and drives the rubber rotating roller 37 to rotate, so that the rubber rotating roller 37 rotates and drives the sliding rod 39 to move, so that the sliding rod 39 drives the sleeve ring 40 and the scraping ring 41 to move, so that the scraping ring 41 cleans the surface of the rubber rotating roller 37, and the above operation is repeated, so that the filter screen 31 and the rubber rotating roller 37 can be continuously cleaned, without manual cleaning of the inlet of the air inlet channel 7, and the air inlet efficiency of the air inlet channel 7 is ensured. or The electric angle jump change attracts the magnetic rotor 17 to continue rotating, thereby making the first paddle 18 continue rotating, making the first paddle 18 suck indoor air, and then making the indoor air enter the air inlet channel 7, and then entering the transition cavity 8 from the air inlet channel 7. While the above-mentioned first paddle 18 rotates, the first driving roller 19 on the first paddle 18 drives the first track 20 to rotate, so that the first driven roller 21 on the first track 20 rotates, thereby making the second paddle 22 rotate, making the second paddle 22 suck air, and then making the air enter the connecting pipe 23 from the inner cavity 9, and then enter the fixed sleeve 24 through the guide of the connecting pipe 23. Part of the air entering the fixed sleeve 24 flows out from the end of the fixed sleeve 24. With the accelerated rotation of the first paddle 18, according to the above principle, the second paddle 22 rotates at a higher speed, so that the amount of air in the fixed sleeve 24 increases. When the increase is greater than the overflow, the air pressure at the end of the fixed sleeve 24 increases, thereby pushing the piston rod 25 to move, so that the piston rod 25 retracts into the fixed sleeve 24, and then the sliding block 26 on the piston rod 25 drives the sliding plate 27 to translate, so that the sliding plate 27 gradually opens the top end of the transition cavity 8, so that the air in the transition cavity 8 can pass through the corresponding through hole 5, and then enter the groove 12 through the corresponding filter hole 13. The activated carbon filter element in the groove 12 filters the indoor air, and finally is discharged from the air outlet 3, completing the purification of the indoor air. As described above, the opening degree of the transition cavity 8 can be automatically adjusted according to the rotating speed of the first paddle 18, that is, the use amount of the activated carbon filter element can be automatically adjusted according to the operating power. When the indoor air purifier operates at a low power, the air sucked by the first paddle 18 can be concentrated in the groove 12 on the outside, avoiding air from escaping into the shell 1, so that the indoor air can be concentrated and filtered, ensuring the permeation efficiency of the activated carbon filter element, thereby ensuring the purification efficiency, and stabilizing the wind speed of the air outlet 3. At the same time, the indoor air purifier can operate at a high power, so that the device can adapt to multiple scenes and requirements, and the activated carbon filter element can be used from the outside to the inside in sequence, so that the saturation of the activated carbon filter element can be judged according to the use condition, without the need for uniform replacement, thereby saving the cost consumption.

[0045] It needs to be further explained that when the first paddle 18 rotates at a constant speed, the air entering efficiency of the fixed sleeve 24 is constant, so that the air pressure at the end of the fixed sleeve 24 no longer increases, and the contraction of the piston rod 25 compresses the air inside the fixed sleeve 24, so that the contraction resistance increases. Therefore, the uniform rotation of the first paddle 18 makes the pressure at both ends of the piston rod 25 the same, so that the piston rod 25 is fixed and does not move, thereby maintaining the opening degree of the transition cavity 8.

[0046] The second paddle 22 absorbs air at the same time, and the air in the air duct 30 is also absorbed, and the air duct 30 is communicated with the ring groove 6, so that the second paddle 22 indirectly absorbs the air in the ring groove 6, and the gradually vacuum between the ring groove 6 and the sealing ring 11 is formed, so that the atmospheric pressure pushes the side wall of the drawer 10 to maintain the sealing between the drawer 10 and the shell 1. According to the above principle, when the operating power of the device is increased, the rotating speed of the second paddle 22 is increased, so that the air flow loss efficiency of the ring groove 6 is increased, and the sealing between the drawer 10 and the shell 1 is indirectly increased. On the contrary, the indoor air can flow back to the ring groove 6, which indirectly reduces the sealing between the drawer 10 and the shell 1, so that the sealing of the drawer 10 can be adjusted according to the purification efficiency, and the air can be prevented from escaping, and the activated carbon filter element can be replaced conveniently.

[0047] In the above process, with the rotation of the second paddle 22, the second paddle 22 drives the second track 33 to rotate through the second driving roller 32, so that the second driven roller 34 on the second track 33 drives the transmission shaft 35 to rotate, so that the connecting rod 36 on the transmission shaft 35 drives the rubber rotating roller 37 to revolve, so that the rubber rotating roller 37 cleans the surface of the filter screen 31. When the rubber rotating roller 37 revolves, it rotates at the same time due to the friction between the rubber rotating roller 37 and the filter screen 31. When the rubber rotating roller 37 rotates, the spiral groove 38 on the rubber rotating roller 37 extrudes the side wall of the sliding rod 39, so that the spiral groove 38 pushes the sliding rod 39, the sleeve ring 40 and the scraping ring 41 to translate, so that the scraping ring 41 cleans the surface of the rubber rotating roller 37. When the sliding rod 39 moves to the other end of the spiral groove 38, because the spiral groove 38 is connected at the head and tail, the sliding rod 39 and the sleeve ring 40 are reset under the rebound of the reset spring, so that the scraping ring 41 is reset, and the above operation is repeated to continuously clean the filter screen 31 and the rubber rotating roller 37. The inlet of the air inlet channel 7 does not need to be cleaned manually, so as to ensure the air inlet efficiency of the air inlet channel 7.

[0048] The embodiments of the application are described in detail above with reference to the drawings, but the application is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and variations of the embodiments can be made without departing from the principles and spirits of the application, and still fall within the protection scope of the application.
