DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 6 As shown, a pathological tissue dehydrator with a jam alarm includes a housing 100, a dehydration cylinder 200 is fixedly installed inside the housing 100, and when dehydrating, the pathological tissue is placed in a disordered tissue basket or an ordered tissue basket, and then the tissue basket is placed inside the dehydration cylinder 200. A cylinder cover 300 is hinged on the top of the housing 100, and the opening of the dehydration cylinder 200 can be sealed by the cylinder cover 300 to prevent the harmful gas inside the dehydration cylinder 200 from being directly discharged and endangering the health of the operator. A stirring drive member 400 is rotatably connected to the bottom of the dehydration cylinder 200, and the stirring drive member 400 can drive the tissue basket inside the dehydration cylinder 200 to rotate, so that the pathological tissue rotates relative to the solvent, which plays a stirring role. A switching assembly 500 is fixedly installed at the bottom of the stirring drive member 400, and a manual drive member 600 is rotatably connected to the top of the switching assembly 500. The two driving modes of the stirring drive member 400 and the manual drive member 600 can be switched through the switching assembly 500. When a freeze or jam occurs, the manual drive member 600 can be switched to drive the tissue basket to rotate, so that the pathological tissue can still be dehydrated in a predetermined manner during the troubleshooting process of the operator. A limit assembly 700 is arranged on the left side of the housing 100. The limit assembly 700 is used to limit the switching assembly 500 horizontally. The limit assembly 700 limits the switching assembly 500 to prevent the stirring drive member 400 from driving the tissue basket to rotate and accidentally switching to the manual drive member 600 driving mode; an alarm assembly 800 is arranged on the surface of the housing 100. The alarm assembly 800 is used to monitor the internal circuit voltage of the housing 100. When the circuit voltage changes due to jam or freeze, an alarm is issued to promptly remind the operator.

[0023] When in use, a water inlet pipe 201 is fixedly installed on the side of the dehydration cylinder 200, and a drain pipe 202 is fixedly installed at the bottom of the dehydration cylinder 200. There are multiple water inlet pipes 201 and drain pipes 202, which are not shown in the figure. Different concentrations of alcohol, distilled water, paraffin, etc. can be injected and discharged into the dehydration cylinder 200 through multiple water inlet pipes 201 and drain pipes 202. The stirring drive member 400 includes a turntable 401 that is connected to the center of the dehydration cylinder 200 through rotation, and two groups of bosses are fixedly installed on the top of the turntable 401. The bosses are used to be plugged into the bottom of the tissue basket, so that when the turntable 401 rotates, the tissue basket can be driven to rotate. A rotating shaft 402 is fixedly installed at the center of the bottom of the turntable 401, and a gear 1 403 is fixedly installed on the surface of the rotating shaft 402. A gear 2 404 is meshed on the right side of the gear 1 403, and a motor 405 is fixedly installed at the center of the bottom of the gear 2 404. The model of the motor 405 is: Y90S-2. Thus, the motor 405 drives the gear 2 404, which in turn drives the assembly of the gear 1 403 and the rotating shaft 402 to rotate, drives the turntable 401 to rotate, and then drives the tissue basket to rotate through the convex column, so that under normal circumstances, the tissue basket is driven to rotate by electricity. A bevel gear 1 406 is fixedly installed at the bottom of the rotating shaft 402, and a bevel gear 2 407 is meshed on the left side of the bevel gear 1 406. A connecting shaft 408 is fixedly installed on the left side of the bevel gear 2 407. The connecting shaft 408 penetrates and is rotatably connected to a support plate 409, which is fixedly installed on the housing 100. A bearing is arranged between the connecting shaft 408 and the support plate 409 to reduce the friction force when the connecting shaft 408 rotates. Thus, when the rotating shaft 402 rotates, the bevel gear 1 406 is driven to rotate synchronously, and then the assembly of the bevel gear 2 407 and the connecting shaft 408 is driven to rotate.

[0024] The alarm component 800 includes a display screen 801 and a buzzer 802 fixedly mounted on the top of the housing 100, and the display screen 801 is a touch screen. The display screen 801 and the buzzer 802 are connected to a single-chip microcomputer, and the single-chip microcomputer is connected to a voltage sensor, and the voltage sensor is electrically connected to the motor 405. The single-chip microcomputer is electrically connected to the motor 405, so that when dehydrating the pathological tissue, the motor 405 can be started and stopped by touching the display screen 801. When the motor 405 fails or other reasons cause the card machine to crash, the voltage in the circuit will change, thereby sending a signal to the single-chip microcomputer through the voltage sensor, and then the single-chip microcomputer drives the buzzer 802 to sound an alarm, and the display screen 801 displays the alarm picture to warn the operator.

[0025] Specifically, the switching assembly 500 includes a base 501 fixedly mounted in the housing 100, and the support plate 409 is fixedly mounted on the base 501, so that the support plate 409 is fixed to the housing 100 through the base 501. A slide rail 502 is fixedly mounted on the top of the base 501, and a slide seat 503 is slidably connected to the surface of the slide rail 502. The slide seat 503 is L-shaped, and the motor 405 is fixedly mounted on the top of the right end of the slide seat 503. The support plate 409 is arched, and the slide seat 503 penetrates and is slidably connected to the bottom of the support plate 409. A spring 1 504 is fixedly mounted between the left end of the slide seat 503 and the left side wall of the housing 100. The elasticity of the spring 1 504 makes the slide seat 503 have a tendency to move to the right. A connecting rod 505 is fixedly installed on the left end of the slide 503, and a boss 506 is fixedly installed on the left end of the connecting rod 505. An escape opening 507 is opened through the left side of the housing 100, and the assembly of the connecting rod 505 and the boss 506 is adapted to the escape opening 507, and the connecting rod 505 is slidably connected in the escape opening 507.

[0026] The position limiting assembly 700 includes a fixed plate 701 fixedly mounted on the left side of the housing 100, and two groups of slide posts 702 are slidably connected through the surface of the fixed plate 701, and a support plate 703 is fixedly mounted on the top of the slide post 702. A groove 704 is provided on the top of the support plate 703, and the boss 506 is inserted into the groove 704. A second spring 705 is sleeved on the outer side of the slide post 702, and the second spring 705 is fixedly mounted between the support plate 703 and the fixed plate 701. Due to the elasticity of the second spring 705, the support plate 703 has a tendency to move upward, so that when the boss 506 is inserted into the groove 704, the connecting rod 505 and the boss 506 are difficult to move in the lateral direction, so that the slide seat 503 is kept in a stable position, and at this time, the second gear 404 and the first gear 403 are kept in a meshing state. When the machine freezes or jams, the support plate 703 can be pressed downward to separate the boss 506 from the support plate 703, and the elasticity of the spring 1 504 can drive the slide 503 to move to the right along the slide rail 502, driving the motor 405 and the gear 2 404 to move to the right. The gear 2 404 is no longer engaged with the gear 1 403, thereby releasing the stirring drive 400 from driving the tissue basket to rotate.

[0027] The manual drive member 600 includes a shaft 601 that passes through and is rotatably connected to the left end of the slide 503. A bearing is also provided between the shaft 601 and the slide 503 to reduce the friction force when the shaft 601 rotates. The shaft 601 passes through and is rotatably connected to the housing 100. A rotating wheel 602 is fixedly installed on the left end of the shaft 601. The rotating wheel 602 is located on the left side of the housing 100. A sleeve 603 is fixedly installed on the right end of the shaft 601. A strip flange 604 is fixedly installed on the surface of the connecting shaft 408. A slot is correspondingly provided on the inner wall of the sleeve 603. The strip flange 604 is adapted to the slot. When the boss 506 is inserted into the embedded groove 704, the sleeve 603 is located on the left side of the connecting shaft 408, and the two are not in contact. When the machine freezes or jams, after the stirring driving member 400 is released to drive the tissue basket to rotate, under the elastic action of the spring 1 504, the shaft 601 moves rightward along with the slide 503, so that the sleeve 603 is sleeved on the outside of the assembly of the connecting shaft 408 and the strip flange 604, and then the rotating wheel 602 is manually rotated to drive the assembly of the connecting shaft 408 and the bevel gear 2 407 to rotate, and then the assembly of the bevel gear 1 406, the rotating shaft 402 and the rotating disk 401 is rotated, and the tissue basket is rotated to ensure that the pathological tissue can be dehydrated as scheduled. When the sleeve 603 moves to the right, and the strip flange 604 is not aligned with the slot on the inner wall of the sleeve 603, the rotating wheel 602 can be manually rotated to align the strip flange 604 with the slot, and under the elastic drive of the spring 1 504, the sleeve 603 is automatically sleeved on the outside of the assembly of the connecting shaft 408 and the strip flange 604.
