DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figures 1-5 The present invention provides a technical solution: a fully automatic biochemical analyzer with waste liquid collection and purification function: Embodiment 1: Refer to the attached manual Figure 1 , Attachment Figure 2 ; It includes a fixed platform 1. Inside the fixed platform 1, there is a stirring chamber. Inside the stirring chamber, there is a stirring shaft structure for the stirring and purification treatment of waste liquid. On the body of the fixed platform 1, there is a water collection mechanism. The water collection mechanism includes two inner cavities 2, and the two inner cavities 2 are arranged in an upper and lower staggered manner. The two inner cavities 2 are respectively opened on the inner wall of the stirring chamber and the body of the fixed platform 1. The inside of one inner cavity 2 is connected to the stirring chamber through a connecting groove 3. The connecting groove 3 is higher than the liquid level of the waste liquid and the height of the waste liquid inlet. The connecting groove 3 is opened on the inner wall of the stirring chamber. Inside one inner cavity 2, there is a sponge plate 5 movably connected. The sponge plate 5 is made of sponge with high elasticity, anti-fatigue and good adsorption. Inside one inner cavity 2, there is a rotating rod 7 embedded and rotatably connected. Four sponge plates 5 are arranged around the rotating rod 7 at equal angles to perform continuous water absorption through position adjustment. Inside the other inner cavity 2, there is a fixed plate 9 fixedly connected. One side of the fixed plate 9 is provided with an arc surface adapted to the inside of the stirring chamber. On the outer surface of the fixed plate 9, there is a high-frequency circuit board 10 electrically connected to an external control circuit, which can cause the fixed plate 9 to generate high-frequency vibration to atomize the liquid water in the waste liquid. On the outer surface of the sponge plate 5, there is a connecting strip 11. The surface of the connecting strip 11 is provided with a convex arc surface, and the radian is consistent with the rotation path of the connecting strip 11. On the outer surface of the connecting strip 11, there is a fixed strip 12 movably connected. The fixed strip 12 is made of a material with compression resistance, wear resistance, corrosion resistance and good sealing performance, and at the same time, the surface is provided with a concave arc surface adapted to the arc surface of the connecting strip 11 to improve the sealing performance of the connecting strip 11 and the water absorption effect of the sponge plate 5. The fixed strip 12 is respectively fixed inside one inner cavity 2 and the connecting groove 3. On the outer surface of the connecting strip 11, there is a pressing strip 13 movably connected. The surface of the pressing strip 13 is also provided with a convex arc surface. By abutting against the connecting strip 11, the sponge plate 5 is extruded to facilitate the collection of the absorbed liquid water. The outer surface of the pressing strip 13 is fixedly connected to the inside of one inner cavity 2. Inside the connecting groove 3, there is a blower 14 electrically connected to an external control circuit, and the surface is also provided with waterproof measures. Inside the connecting groove 3, there is an air duct 15 connected. The outer surface of the air duct 15 is fixedly embedded with the body of the fixed platform 1. One end of the rotating rod 7 penetrates the body of the air duct 15 and extends into the inside of the air duct 15. Inside one inner cavity 2, there is a water pump 16 fixedly installed. The water pump 16 is electrically connected to an external control circuit. The output end of the water pump 16 is connected to a spray pipe 4 through a water pipe. The spray pipe 4 is arranged in a ring shape and has uniform spray holes below. At the same time, the spray pipe 4 is higher than the connecting groove 3. The spray pipe 4 is fixedly installed above the inside of the stirring chamber.

[0021] In this embodiment, when stirring and purifying the waste liquid inside the stirring chamber, the high-frequency circuit board 10 is powered on to cause the fixed plate 9 to generate high-frequency vibration, so that the liquid water in the waste liquid is atomized. At the same time, the fan 14 works to extract the air inside the stirring chamber through the connecting groove 3. The air carries the atomized water droplets into the inside of the connecting groove 3 and is absorbed by the sponge plate 5. The air then circulates back to the inside of the stirring chamber through the air duct 15. When the sponge plate 5 is full of water absorption, the rotating rod 7 drives it to rotate for position adjustment, so that the adjacent sponge plate 5 continues to absorb the atomized water droplets. At the same time, during the rotation process, the connecting strip 11 and the fixed strip 12 contact through the arc surface to improve the sealing performance and thus improve the absorption effect of the sponge plate 5. Moreover, the connecting strip 11 corresponding to the full sponge plate 5 contacts and abuts against the abutting strip 13 during movement, so as to be pushed to squeeze the sponge plate 5, so that the atomized water droplets condense and drip into the inside of the upper inner cavity 2 for collection. After the waste liquid is discharged, the water pump 16 extracts the collected liquid water to the spray pipe 4 and sprays it to wash the stirring shaft, thereby saving water resources and improving the treatment efficiency.

[0022] Embodiment 2: On the basis of Embodiment 1, refer to the attached drawings of the specification Figure 1 and Figure 3 ; An extrusion assembly 6 is arranged outside the sponge plate 5. The extrusion assembly 6 includes a fixed frame 61. The fixed frame 61 is U-shaped. The outer surface of the fixed frame 61 is fixedly connected to the outer surface of the rotating rod 7. The outer surface of the fixed frame 61 is respectively movably connected to the inside of one side inner cavity 2 and the connecting groove 3. The outer surface of the fixed frame 61 is fixedly connected to the outer surface of the sponge plate 5. A sliding groove 62 is opened on the outer surface of the fixed frame 61. Through the connection with the sponge plate 5, the sliding groove 62 improves the stability of the sponge plate 5 when it is extruded. The outer surface of the sponge plate 5 is movably connected to the inside of the sliding groove 62. A rubber strip 63 is fixedly connected to the outer surface of the fixed frame 61. The rubber strip 63 improves the sealing performance between the connecting strip 11 and the fixed frame 61. And when not being extruded, the rubber strip 63 is in a stretched state, and through deformation, it is convenient for the movement of the connecting strip 11 during extrusion. The outer surface of the rubber strip 63 is fixedly connected to the outer surface of the connecting strip 11. A connecting block 64 is movably connected to the outer surface of the rubber strip 63. The outer surface of the connecting block 64 is fixedly connected to the outer surface of the connecting strip 11. The outer surface of the connecting block 64 is movably connected to the inside of the sliding groove 62. A spring rod 65 is fixedly connected to the outer surface of the connecting block 64. The output end of the spring rod 65 facilitates the reset of the sponge plate 5 and the connecting strip 11 through rebound. The outer surface of the spring rod 65 is fixedly connected to the inside of the sliding groove 62.

[0023] In this embodiment, when the connecting bar 11 moves and contacts the abutting bar 13, it is pushed, thereby squeezing the sponge board 5. The two sides of the squeezed sponge board 5 move inside the slide groove 62, thereby improving the overall stability of the sponge board 5. At the same time, the rubber strip 63 is separated from the stretching and restoring shape, which also facilitates the movement of the connecting bar 11. At the same time, the connecting bar 11 compresses the output end of the spring rod 65 through the connecting block 64. When the connecting bar 11 is separated from the abutment with the abutting bar 13, the output end of the spring rod 65 rebounds, so that the connecting block 64 pushes the connecting bar 11 to reset, so that the rubber strip 63 and the sponge board 5 are stretched again to achieve continuous water absorption.

[0024] Embodiment 3: Based on Embodiment 2, refer to the attached Figure 1 , Attachment Figure 4 ; The outer surface of the rotating rod 7 is provided with a toggle assembly 8, which includes a vertical rod 81. The lower position of the vertical rod 81 is made of a ball screw structure. The outer surface of the vertical rod 81 is rotatably connected to the inside of the air duct 15. One end of the vertical rod 81 is fixedly connected to a fan blade 83. The fan blade 83 can drive the vertical rod 81 to rotate by contacting the flowing air. The outer surface of the vertical rod 81 passes through a support plate 84 that is rotatably connected. The connection between the support plate 84 and the vertical rod 81 has an axial limiting measure. The outer surface of the support plate 84 is fixedly connected to the inside of the air duct 15. The outer surface of the vertical rod 81 passes through a movably connected missing gear 85. The outer surface of the missing gear 85 is meshed with a rotating gear 86. The rotating gear 86 and the missing gear 85 are both made of bevel gears, and through intermittent contact, the rotating rod 7 is intermittently rotated to adjust the position of the sponge board 5, and the rotation angle of the rotating rod 7 is the same as the angle between the two adjacent sponge boards 5. The outer surface of the rotating gear 86 is fixedly connected to one end of the rotating rod 7. The vertical rod 81 The outer surface of the slide post 87 is threadedly connected with a slide post 87, which is made of the same material as the fixed strip 12, which can not only make the air flow unidirectionally inside the air duct 15, but also improve the stability of the vertical rod 81. At the same time, a connecting channel is provided in the middle part of the slide post 87, and the interior of the connecting channel is fixedly connected to the sliding end of the ball screw. The outer surface of the slide post 87 is slidably connected to the interior of the air duct 15, and the outer surface of the slide post 87 is embedded with a swivel 88 for rotation. The cross section of the swivel 88 is T-shaped, which improves the stability of the connection between the missing gear 85 and the slide post 87, so that the missing gear 85 can slide up and down with the slide post 87, and the outer surface of the swivel 88 is fixedly connected to the outer surface of the missing gear 85. The outer surface of the vertical rod 81 is provided with a slot 89, and the interior of the slot 89 is slidably connected with a block 810. The cooperation of the block 810 and the slot 89 can make the missing gear 85 rotate synchronously with the vertical rod 81, and the outer surface of the block 810 is fixedly connected to the penetration of the missing gear 85.

[0025] In this embodiment, when the flowing air flows inside the air duct 15, the vertical rod 81 rotates following the contact with the fan blade 83. Below the vertical rod 81, through a ball screw structure, the sliding column 87 moves up and down along the vertical rod 81, which can not only improve the stability of the vertical rod 81, but also make the air flow unidirectionally. At the same time, when the sliding column 87 descends, through the action of the rotating ring 88, the missing gear 85 is driven to descend synchronously, and when the missing gear 85 is at the lowest position, it contacts the rotating gear 86. At the same time, through the cooperation of the clamping block 810 and the clamping groove 89, the lower part of the vertical rod 81 drives the missing gear 85 to rotate, so as to drive the rotating rod 7 to rotate through the rotating gear 86, realizing the position adjustment of the sponge plate 5.

[0026] Embodiment 4: On the basis of Embodiment 3, refer to the attached drawings of the specification Figure 1 and Figure 5 ; A sealing unit 82 is arranged outside the vertical rod 81. The sealing unit 82 includes an air outlet 821 which is arranged obliquely downward to prevent liquid from accumulating inside. The air outlet 821 is opened on the inner wall of the stirring chamber. The inside of the air outlet 821 is communicated with one end of the air duct 15. A fixed frame 822 is fixedly connected inside the air outlet 821. A baffle 823 is movably connected to the outer surface of the fixed frame 822. A magnetic attraction measure is arranged on one side of the baffle 823 and the surface of the fixed frame 822 so that the baffle 823 and the fixed frame 822 are closely attached. A support rod 824 is fixedly connected through the body of the baffle 823. Both ends of the support rod 824 are rotatably connected through connecting plates 825. The outer surface of the connecting plate 825 is fixedly connected to the outer surface of the fixed frame 822. A torsion spring 826 is sleeved on the outer surface of the support rod 824. The torsion spring 826 can reset the baffle 823 through elastic force and make the baffle 823 and the fixed frame 822 closely attached together. Both ends of the torsion spring 826 are fixedly connected to the outer surface of the connecting plate 825 and the baffle 823 respectively.

[0027] In this embodiment, when the air in the air duct 15 flows into the inside of the air outlet 821, the baffle 823 can be pushed to move through air pressure, so that the baffle 823 rotates around the support rod 824, disengaging from the shielding of the fixed frame 822, and enabling the air to flow back into the inside of the stirring chamber through the fixed frame 822 and the air outlet 821. And when the baffle 823 rotates, the torsion spring 826 is compressed. When the air stops flowing, the torsion spring 826 rebounds to reset the baffle 823 to shield the fixed frame 822, and at the same time, the two are closely attached through magnetic attraction.
