[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1 See also Figures 1 to 13, the present invention provides a technical solution: a device for a household haze removal and oxygen increasing fresh air system, comprising: a housing 1, an air inlet 2 is fixedly connected to the top of the housing 1, an air outlet 3 is fixedly connected to the bottom of the housing 1, a mounting plate 4 is fixedly connected inside the housing 1, a fan 5 is fixedly connected inside the mounting plate 4, a mounting frame 6 is fixedly connected inside the housing 1, a first mounting groove 7 is arranged inside the housing 1, detection mechanisms 8 are arranged at both the upper and lower ends of the housing 1, a motor 9 is fixedly connected inside the first mounting groove 7, a rotating shaft 10 is fixedly connected to the output end of the motor 9, two first electric push rods 11 are fixedly connected to the outer periphery of the rotating shaft 10, an electromagnet 12 is fixedly connected to the output end of the first electric push rod 11, a thin iron block 13 is magnetically attracted outside the electromagnet 12, an H13 high-efficiency filter 14 is fixedly connected outside the thin iron block 13, a controller 15 is fixedly connected inside the first mounting groove 7, a cleaning mechanism 16 is arranged outside the mounting frame 6, a pushing mechanism 17 is arranged at one end inside the mounting frame 6, a blocking mechanism 18 is arranged outside the housing 1, a fixing rod 19 is fixedly connected to the inner side of the housing 1, a plurality of torsion springs 20 are sleeved on the outer periphery of the fixing rod 19, and a limiting block 21 is fixedly connected to the top of the torsion spring 20; During use, the blower 5 is started. The blower 5 sucks the indoor air from the air inlet 2 into the interior of the housing 1, filters it through the H13 high-efficiency filter 14, and then discharges it from the air outlet 3. When the air is inlet and outlet, the detection mechanism 8 detects the air pressure at the air inlet 2 and the air outlet 3, feeds back the detected signal to the controller 15 to obtain a difference value, and judges whether the H13 high-efficiency filter 14 is blocked. If it is not within the applicable range, the H13 high-efficiency filter 14 is blocked. The first electric push rod 11 pushes the electromagnet 12 close to the thin iron sheet of the H13 high-efficiency filter 14, adsorbs the thin iron sheet, and then contracts the first electric push rod 11 to pull the H13 high-efficiency filter 14. The H13 high-efficiency filter 14 abuts against the limit. The limit block 21 bears the thrust from the H13 high-efficiency filter 14. The limit block 21 drives the torsion spring 20, causing the torsion spring 20 to deform and generate an elastic force. When the H13 high-efficiency filter 14 is pulled out of the mounting frame 6, the limit block 21 is pulled back to its original position by the torsion spring 20. The first motor 9 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives another first electric push rod 11 and the H13 high-efficiency filter 14. Another first electric push rod 11 pushes the electromagnet 12 and the H13 high-efficiency filter 14. The H13 high-efficiency filter 14 and the limit block 21 are pushed. One end of the top of the limit block 21 is arc-shaped, enabling the H13 high-efficiency filter 14 to push the limit block 21 and slide into the interior of the mounting frame 6. When the H13 high-efficiency filter 14 pushes the limit block 21, the limit block 21 causes the torsion spring 20 to deform and generate an elastic force. After the H13 high-efficiency filter 14 is installed into the interior of the mounting frame 6, the limit block 21 is driven back to its original position by the torsion spring 20. After the H13 high-efficiency filter 14 is installed and the device is operated, the device can be used normally. After use, when the device is turned off, using the remaining power, the first motor 9 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the original H13 high-efficiency filter 14 to return to its original position. Through the cleaning mechanism 16, the H13 high-efficiency filter 14 is automatically cleaned. When the device is used again, the detection mechanism 8 detects the air pressure at the air inlet 2 and the air outlet 3 again to judge whether the H13 high-efficiency filter 14 is still blocked. If the air pressure difference is not within the applicable range, the blocked H13 high-efficiency filter 14 is automatically replaced with a clean H13 high-efficiency filter 14 again. After use, the blocking mechanism 18 ends, and the pushing mechanism 17 pushes out the blocked H13 high-efficiency filter 14 to prompt the user to replace the H13 high-efficiency filter 14 in time.

[0020] The detection mechanism 8 includes a first mounting block 80. A pressure sensor 81 is fixedly connected to the outside of the first mounting block 80. A pressing block 82 is fixedly connected to the outside of the pressure sensor 81. The pressing block 82 is rotatably connected inside the first mounting block 80. The pressing block 82 abuts against the pressure sensor 81. When in use, the wind blows the pressing block 82, and the pressing block 82 rotates inside the first mounting block 80. The other end of the pressing block 82 abuts against the pressure sensor 81 to detect the magnitude of the wind force. The values detected by the air inlet 2 and the air outlet 3 are both fed back to the controller 15 to determine whether the pressure difference is within the applicable range. If it is within the applicable range, the H13 high-efficiency filter 14 is not blocked. If it is not within the applicable range, the H13 high-efficiency filter 14 is blocked.

[0021] The cleaning mechanism 16 includes a first mounting shell 160, a second mounting shell 165, and an electrostatic dust collection box 166. The outside of the first mounting shell 160 is fixedly connected to the outside of the left end of the mounting frame 6. A motor 161 is fixedly connected to the top of the first mounting shell 160. The output end of the motor 161 is fixedly connected to a threaded rod 162. A second mounting block 163 is threadedly connected to the outer circumference of the threaded rod 162. A cleaning brush 164 is fixedly connected to the outside of the second mounting block 163. The outside of the second mounting shell 165 is fixedly connected to the outside of the right end of the mounting frame 6. The bottom of the electrostatic dust collection box 166 is slidably connected to the inside of the mounting frame 6. After the device is used up, using the remaining power, the motor 161 is started. The motor 161 drives the threaded rod 162 to rotate. The threaded rod 162 drives the second mounting block 163 to move inside the first mounting shell 160 and the second mounting shell 165. The second mounting block 163 drives the cleaning brush 164 to clean the H13 high-efficiency filter 14, and the dust cleaned falls into the electrostatic dust collection box for collection.

[0022] The pushing mechanism 17 includes two second mounting grooves 170. Both of the two second mounting grooves 170 are opened inside the mounting frame 6. Two first springs 171 are fixedly connected to the inside of the second mounting grooves 170. A pushing block 172 is fixedly connected to the outside of the second mounting grooves 170. When the H13 high-efficiency filter 14 is installed, since one end of the pushing block 172 is arc-shaped, the H13 high-efficiency filter 14 will push the pushing block 172 into the second mounting groove 170. When the blocking mechanism 18 is unlocked, the pushing block 172 will push the electrostatic dust collection box and the H13 high-efficiency filter 14 out of the mounting shell.

[0023] The blocking mechanism 18 includes a second spring 180, a baffle 183, a fixing block 186 and a mounting bracket 1811. One end of the second spring 180 is fixedly connected to the inner wall of the mounting frame 6, and the other end of the second spring 180 is fixedly connected to a first slider 181. A push rod 182 is fixedly connected to the outside of the first slider 181. The outside of the baffle 183 is rotatably connected to the inside of the housing 1. A third spring 184 is fixedly connected to the inside of the baffle 183, and the other end of the third spring 184 is fixedly connected to a latch 185. The outside of the fixing block 186 is fixedly connected to the outside of the housing 1, and a support rod 187 is fixedly connected to the inside of the fixing block 186. Two fourth springs 188 are sleeved on the outer periphery of the support rod 187. Two toggle blocks 189 are slidably connected to the outer periphery of the support rod 187. An arc-shaped block 1810 is fixedly connected to the outside of the toggle block 189. The outside of the mounting bracket 1811 is fixedly connected to the outside of the housing 1, and a second electric push rod 1812 is fixedly connected to the outside of the mounting bracket 1811. The output end of the second electric push rod 1812 is fixedly connected to a second slider 1813. When in use, when it is necessary to replace the H13 high-efficiency filter 14, the second electric push rod 1812 pushes the second slider 1813, and the second slider 1813 slides into the inside of the fixing block 186. The second slider 1813 abuts against the arc-shaped block 1810, and the second slider 1813 is pushed by the arc-shaped block 1810. The arc-shaped block 1810 drives the toggle block 189 to slide towards both ends on the outer periphery of the support rod 187 and compresses the fourth spring 188. The fourth spring 188 generates an elastic force. When the toggle block 189 moves, it pushes the latch 185, and the latch 185 slides into the inside of the baffle 183 and compresses the third spring 184, causing the third spring 184 to generate an elastic force. After the latch 185 slides into the inside of the baffle 183, the second spring 180 pushes the first slider 181, the first slider 181 drives the push rod 182, and the push rod 182 pushes the baffle 183 to open the baffle 183. When closing the baffle 183, directly push the baffle 183, and the latch 185 abuts against the fixing block 186 and slides into the inside of the baffle 183 and compresses the third spring 184. The third spring 184 generates an elastic force. When the latch 185 and the card hole of the fixing block 186 are aligned, the latch 185 is pushed by the third spring 184 and slides into the inside of the fixing block 186, and the baffle 183 and the fixing block 186 cooperate to lock self-locking.
