[0043] The following will explain in detail the specific implementation manners of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0044] As Figures 1-5 shown, an indoor automatic cruise air purification device provided by the present invention includes: a navigation module 16, an air detection module 17, a control module 18, a mobile base 1 and a purifier main body 2;

[0045] The air detection module 18 is used to detect the concentration of various pollutants in the indoor air in real time;

[0046] The navigation module 16 is used to scan the indoor environment in real time to construct an indoor map, and plan the moving path of the device according to the indoor map and the instructions of the control module 18;

[0047] The control module 18 is used to control the moving path of the mobile base 1 and the operating parameters of the purifier main body 2 according to the data of the air detection module 17;

[0048] The purifier main body 2 is fixedly arranged at the upper end of the mobile base 1, and both sides of the purifier main body 2 are respectively and liftably provided with a plurality of intake ends 4 for sucking indoor air into the purifier main body 2 for purification through a first lifting mechanism 6.

[0049] In the above solution, the intake end 4 includes: an intake hood and a fan arranged inside it, and indoor gas is sucked into the purifier main body 2 through the fan so that the purifier main body 2 can purify the gas.

[0050] During use, the navigation module 16 scans the indoor environment to construct an indoor map. The control module 18 sets initial air quality standards and purification parameters. The air detection module 17 continuously detects the air quality data at the current location and transmits the data to the control module 18. The control module 18 determines the air quality status of the current area based on the air quality data. The control module 18 determines the air quality level of the current area, which is divided into four levels: excellent, good, medium, and poor. If the air quality level is poor, the control module 18 will increase the fan speed at the air inlet end 4 of the purifier main body 2 to the maximum; if the air quality level is excellent, the device will continue to cruise at a normal speed. If the air quality is relatively poor, the control module 18 controls the purifier main body 2 to increase the purification intensity, such as increasing the fan speed; if the air quality is good, the entire device continues to cruise along the preset path through the mobile base 1. The navigation module 16 adjusts the moving path of the device in real time according to the indoor map and the air quality distribution, and preferentially moves to the area with relatively poor air quality. After the device moves to the designated area, the purifier main body 2 starts to work, inhaling the gas into the purifier main body 2 through multiple air inlet ends 4 for air purification treatment, and finally discharging the treated gas from its interior. During the purification process, the air detection module 17 continuously detects the air quality. When the air quality reaches the preset standard, the control module 18 controls the device to move to the next area. The device continuously repeats the above processes of air detection, path planning, and air purification, and conducts cyclic cruising indoors until the air quality of all areas indoors reaches the excellent level.

[0051] In addition, the height of multiple air inlet ends 4 of the purifier main body 2 can be adjusted through the first lifting mechanism 6. Therefore, when there is smoke indoors and the smoke will quickly flow upward due to its very light quality, at this time, the height of the air inlet end 4 can be adjusted through the first lifting mechanism 6 so that the air inlet end 4 can rise upward to a suitable position, so that the rising air inlet end 4 can be as close as possible to the smoke, thereby quickly inhaling the smoke into the purifier main body 2 through the air inlet end 4 for rapid purification treatment, preventing the smoke floating to the high places indoors from being effectively purified.

[0052] In the above solution, the control module 18 is installed on the mobile base 1 or the purifier main body 2, and it uses a single-chip microcomputer as the control core, such as the STM32 series single-chip microcomputer. A control program is written to realize the control of the air detection module 17, the mobile base 1, and the purifier main body 2. The control module 18 is communicatively connected to the air detection module 17, the mobile base 1, and the purifier main body 2 to receive the data transmitted by the air detection module 17, and determines the air quality status of the current area according to the preset air quality standards. According to the air quality status, it controls the moving path of the mobile base 1 and the operating parameters of the purifier main body 2, such as the fan speed.

[0053] In a preferred embodiment of the present invention, the first lifting mechanism 6 includes: a power shaft 601, a power gear 602, and a power rack 603; wherein,

[0054] The interior of the moving base 1 is a hollow structure, and at least two power shafts 601 are horizontally rotatably arranged at intervals inside it. Two power gears 602 are coaxially and fixedly arranged on each power shaft 601 on both sides of the purifier main body 2. On each side of each power shaft 601, two power racks 603 that are vertically arranged and can be lifted and are meshed with the two power gears 602 on each power shaft 601 are respectively arranged inside the moving base 1. The tops of the two power racks 603 respectively pass through the top of the moving base 1 and are fixedly provided with an air inlet end 4.

[0055] In the above solution, by rotating the power shaft 601 to drive the two power gears 602 on its shaft body to rotate, during the rotation of the two, the two power racks 603 engaged with them respectively can be driven to rise in the vertical direction. During the rising process of each power rack 603, the air inlet end 4 arranged on its top is lifted to adjust the height of the air inlet end 4.

[0056] In a preferred embodiment of the present invention, the first lifting mechanism 6 further includes: a second lifting mechanism 604; wherein,

[0057] The interior of each power rack 603 is a hollow structure, and a second lifting mechanism 604 is vertically fixedly arranged inside the power rack 603 with its opening facing upwards. The second lifting mechanism 604 includes: an electric telescopic rod; wherein,

[0058] The telescopic end of the electric telescopic rod passes through the opening of the power rack 603 and extends above the moving base 1. A support plate 3 is horizontally and fixedly arranged at the top of the second lifting mechanism 604, and an air inlet end 4 is fixedly arranged on the support plate 3.

[0059] In the above solution, the electric telescopic rod is a servo electric cylinder. The servo electric cylinder is a modular product that integrates a servo motor and a lead screw. Its speed is 0.1 - 2 m / s. Because of the closed-loop servo control, the control accuracy is relatively high. It has the characteristics of low cost and flexible configuration, and is the best substitute for hydraulic cylinders and air cylinders.

[0060] When in use, by driving the telescopic end of the electric telescopic rod to extend from its cylinder, the air inlet end 4 fixed thereon by the support plate 3 can be raised together, so that the height of the air inlet end 4 can be further adjusted so that the air inlet end 4 can be raised higher, so that air at different heights can be sucked into the purifier body 2 to purify the gas.

[0061] In a preferred embodiment of the present invention, a plurality of fixed seats 7 are spaced apart and liftably arranged at the bottom end of the mobile base 1 through a third lifting mechanism, and a walking wheel 8 is rotatably arranged under each fixed seat 7, and the third lifting mechanism is transmission-connected to the first lifting mechanism 6.

[0062] In the above scheme, when in use, the third lifting mechanism is used to drive the fixed seat 7 and the walking wheel 8 fixed thereunder to rise and fall, so that the walking wheel 8 can reversely push the mobile base 1 to rise under the action of the third lifting mechanism, and during the rising process of the lifting base 1, the air inlet end 4 of the purifier body 2 fixed thereon can be driven to rise together, thereby indirectly driving the air inlet end 4 to continue to rise through the third lifting mechanism. Therefore, under the coordinated use of the first lifting mechanism, the second lifting mechanism and the third lifting mechanism, the air inlet end 4 of the purifier body 2 can rise to a higher position, so that the purifier body 2 can inhale the air at various heights (various positions) in the room into its interior for purification through the liftable air inlet end 4, thereby being able to fully purify the air in the room.

[0063] In addition, the running wheels 8 of the mobile base 1 are driven by a brushless DC motor to make them more efficient and reliable. There are at least two running wheels 8 (two running wheels 8 arranged in front of the mobile base 1 are steerable), and the steerable running wheels 8 are controlled by a steering gear, so that the mobile base 2 can be flexibly steered.

[0064] The device also includes a battery to provide electrical energy to the entire device, and the battery shell adopts a lithium battery to make it have a higher energy density and a longer battery life.

[0065] In a preferred embodiment of the present invention, the third lifting mechanism comprises: a worm 901, a worm wheel 902 and a lifting slider 903; wherein,

And in each of the moving bases 1 beside each worm wheel 902, a worm 901 meshed with it is vertically and rotatably arranged. And on each of the worms 901 located below the worm wheels 902, threads are uniformly fixedly arranged, and a lifting slider 903 capable of lifting along its axial direction is threadedly connected to its shaft body.

[0067] In the above solution, during use, when the power shaft 601 drives the two power gears 602 on its shaft to rotate, it drives the power tooth plates 603 meshed with them respectively to drive the intake end 4 to rise. At the same time, the power shaft 601 drives the two worm wheels 902 on it to rotate, so as to drive the two worms 901 meshed with them to rotate. And during the rotation of each worm 901, through the cooperation of the threads on its surface and the lifting slider 903, it can drive the lifting slider 903 to descend through the support legs 15, so that the support legs 15 extend from the inside of the moving base 1, thereby lifting the moving base 1, so as to continue to drive the purifier main body 2 fixed on the moving base 1 and the intake end 4 fixed on it to rise through the third lifting mechanism, so as to further adjust the height of the intake end 4.

[0068] In a preferred embodiment of the present invention, the purifier main body 2 includes: a housing; wherein,

[0069] Water is contained at the bottom end inside the housing, and inverted L-shaped water inlet pipes 10 are respectively fixedly arranged at intervals and vertically on both side walls of the housing.

Activated carbon particles are stored inside each storage net box 11. A one-way exhaust pipe 12 is fixedly communicated with the top of the housing.

[0070] In the above solution, when the air inlet end 4 passes the indoor air through the corrugated hose 5 and the water inlet pipe 10 into the water in the purifier main body 2 to wash the indoor air for preliminary filtration of the indoor air, filtering out impurities such as dust, dust or hair in the air. The gas after being washed with water rises and passes through each of the storage mesh boxes 11 from bottom to top in sequence, and undergoes secondary purification such as formaldehyde removal through the activated carbon particles stored therein. Finally, the purified gas is discharged through the one-way exhaust pipe 12 at its top.

[0071] A one-way valve is fixedly arranged on the one-way exhaust pipe 12, and the medium flow direction can only be discharged from the inside of the purifier main body 2 to the outside through the one-way exhaust pipe 12.
