Example 2

On the basis of Embodiment 1, as shown in Fig. 1, Fig. 7 and Fig. 8, a transmission mechanism 9 is also included, and the transmission mechanism 9 includes a rotating disc 91, a connecting block 92, a movable frame 93, a rotating block 94 and Fixed block 95, base 81 top left side front and rear symmetry is connected with fixed block 95 by bolt, all sliding type is provided with rotating block 94 on two fixed blocks 95, and two rotating blocks 94 outsides are all rotating and are provided with can indirectly make disinfectant The movable frame 93 of automatic ejection, two rotating shafts outsides are all provided with rotating disk 91, and two rotating disks 91 upper sides are all provided with connecting piece 92, and two connecting pieces 92 are all rotated with the movable frame 93 lower sides of same side. Linked to each other, two rotating blocks 94 all contact with lifting plate 4.

When people push this device to disinfect the hospital ground, the roller 82 on the left rotates, and the rotating shaft rotates accordingly, and the rotating shaft rotates to drive the rotating disk 91 to rotate, so that the rotating disk 91 drives the connecting block 92 to rotate, and the connecting block 92 is pulled to move Frame 93 moves downwards, and movable frame 93 drives rotating block 94 to move downwards, and return force spring 5 is in tension state at initial stage, and rotating block 94 moves downwards and just no longer blocks lifting plate 4, and lifting plate 4 just can be in return force spring. 5 drives the lifting frame 3 to move downwards under the reset action of 5, so that the lifting frame 3 squeezes the disinfectant water until the spray nozzle 2 is sprayed out. Drive the rotating block 94 to move upwards and reset, and the rotating block 94 will push the lifting plate 4 and the lifting frame 3 to move upwards, and the return force spring 5 will stretch accordingly, so that the disinfectant will no longer be sprayed out, and the device will continue to move, so that the rotating plate 91 will continue to move. Rotate, and then the connecting block 92 repeatedly drives the movable frame 93 to move up and down, and the lifting frame 3 moves up and down repeatedly, so that the disinfectant water is sprayed intermittently, so that the device can spray the disinfectant water intermittently during the movement, so as to achieve automatic spraying The effect is that there is no need for two people to assist in the disinfection of the hospital floor, which reduces manpower. After the device stops moving, the disinfectant will no longer be sprayed.

Shown in Fig. 1, Fig. 9, Fig. 10 and Fig. 11, also comprise rotating mechanism 10, and rotating mechanism 10 comprises support frame 101, connecting frame 102, threaded rod 103, movable block 104 and hairbrush 105, lifting plate 4 The support frame 101 is connected to the front and back symmetrically by screw connection, the connecting frame 102 is connected between the bottom right side of the two supporting frames 101, the connecting frame 102 is connected to the threaded rod 103 slidingly in the middle, and the bottom of the threaded rod 103 is provided with a movable block 104, the movable block 104 is connected to the middle of the base 81 in a rotational manner, and the bottom of the movable block 104 is provided with a brush 105 that can evenly cover the ground with disinfectant, and the brush 105 is located at the bottom of the base 81.

When disinfecting the hospital ground, the lifting plate 4 moves downwards to drive the lifting frame 3 to move downwards and extrude the disinfectant water to spray out to disinfect the ground, and the lifting plate 4 will also drive the supporting frame 101 to move downwards simultaneously, so that Drive connecting frame 102 to move down, and connecting frame 102 just drives threaded rod 103 to rotate, and threaded rod 103 drives movable block 104 and hairbrush 105 to rotate, and hairbrush 105 rotates and just can brush the disinfection water sprayed on the ground, makes Disinfectant water evenly covers the ground, and when lifting plate 4 moves upwards and resets, it will also drive support frame 101 to move upwards, so that support frame 101 drives threaded rod 103, movable block 104 and hair brush 105 to reverse and reset, and hair brush 105 can Brush the ground again, so that when the disinfectant is sprayed out, the hairbrush 105 will automatically rotate to make the disinfectant evenly smear on the ground, which can achieve a better disinfection effect. After the device stops moving, the disinfectant will stop spraying , the hairbrush 105 will no longer rotate.

Shown in Fig. 1 and Fig. 12, also includes cleaning mechanism 11, and cleaning mechanism 11 includes installation block 111, torsion spring 112, turret 113 and roller 114, and the left side of base 81 is symmetrically connected by the mode of screw connection. Mounting block 111, the rotating type between two mounting blocks 111 is provided with a turret 113, the rotating type in the middle of the turret 113 is provided with a roller 114 that can clean the ground, the front and rear sides of the right part of the turret 113 and the mounting blocks on the same side Two torsion springs 112 are connected between 111 .

When using this device to spray disinfectant on the ground, when the device is not in contact with the ground, the height of the roller 114 is lower than that of the roller 82. After the device is on the ground of the hospital, the roller 114 will be passively rotated when it contacts the ground. Drive the turret 113 to rotate, so that the torsion spring 112 is deformed, so that the force of the deformation of the torsion spring 112 makes the roller 114 close to the ground. When people push the device to move, the roller 114 will rub against the ground, and the friction force will make the roller 114 close to the ground. 114 rotates, and the drum 114 can remove some debris and dust on the ground to achieve the purpose of cleaning, so that the ground is first cleaned by the drum 114, then sprayed with disinfectant through the nozzle 2, and finally the disinfectant is sprayed by the brush 105. More evenly, such a series of operations can make the hospital floor more tidy, without the need to manually clean the floor in advance. After the floor is disinfected, if the device is separated from the floor, the roller 114 will no longer be in contact with the floor. The frame 113 will drive the roller 114 to reversely rotate and reset under the reset action of the torsion spring 112 .

Shown in Fig. 1, Fig. 13 and Fig. 14, also include scraper mechanism 12, scraper mechanism 12 includes guide frame 121, sliding frame 122, scraper 123 and back-moving spring 124, and both sides of turret 113 front and back are all provided with. There is a guide frame 121, a sliding frame 122 is provided between the two guiding frames 121, the bottom of the sliding frame 122 is provided with a scraper 123 capable of scraping off the impurities on the surface of the drum 114, the front and rear sides of the top of the sliding frame 122 and the same side Return springs 124 are connected between the guide frames 121 , and the scraper 123 is in contact with the roller 114 .
