Description

Technical Field

[0001] The present application relates to the technical field of cleaning of sputum suction devices, and specifically to a cleaning device and a cleaning method for a sputum suction device. Background Art

[0002] In modern medical practice, suctioning is a common nursing procedure, especially for patients in intensive care units, postoperative patients, and those with respiratory diseases. The purpose of suctioning is to clear secretions from the airway to maintain airway patency, reduce the risk of infection, and improve the patient's respiratory function. Traditional suction equipment typically consists of a suction pump and a single collection container for collecting sputum and other secretions.

[0003] Traditional suction equipment requires frequent manual cleaning and disinfection to maintain equipment hygiene and prevent cross-infection. This not only increases the workload of medical staff but also increases the risk of infection for patients, especially during peak hours or when staff is insufficient. Furthermore, when the collection container is full, the suctioning operation must be stopped to empty and clean it, interrupting the treatment process and preventing the patient's sputum from being cleared in a timely manner. For critically ill patients who require continuous suctioning, this interruption may increase the risk of airway obstruction.

[0004] Medical equipment multi-enzyme cleaning agent uses a new type of dispersible scale inhibitor as raw material, which not only provides high-efficiency scale inhibition performance, but also increases cleaning performance and disperses dirt. At the same time, this substance can chelate calcium ions on bacterial cell membranes, allowing preservatives to more easily penetrate into the interior of the bacteria, achieving better anti-corrosion effects.

[0005] Therefore, it is necessary to provide a sputum suction device with a cleaning device to solve the above problems.

[0006] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the Invention

[0007] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a cleaning device for a sputum suction device, which can achieve the effect of continuous sputum suction without stopping the device for cleaning.

[0008] The technical solution adopted by the present application to solve its technical problem is: a cleaning device for a sputum suction device, comprising a body, a processing tank, a sputum suction mechanism, and a cleaning mechanism; the processing tank is fixedly mounted on the body, the sputum suction mechanism and the cleaning mechanism are arranged in the processing tank, and the input end of the sputum suction mechanism extends out of the top of the processing tank; a partition plate is fixedly mounted inside the processing tank, the partition plate divides the inner cavity of the processing tank into a placement cavity and a recovery cavity; the sputum suction mechanism is located in the placement cavity, and the output end passes through the partition plate and is connected to the recovery cavity, the bottom of the recovery cavity is provided with a guide port, and the port of the guide port is connected to an external recovery bin through a pipeline; thereby, sputum sucked by the sputum suction mechanism is placed in the recovery cavity, and the cleaning mechanism processes the sputum to provide a temporary storage space for subsequent sputum suctioning actions; the cleaning mechanism and the sputum suction mechanism are divided into zones to achieve the effect of continuous sputum suction without stopping the machine for cleaning;

[0009] The cleaning mechanism includes a conveying component, a distributor, and a spray head; the conveying component is rotatably installed in the recovery chamber; the distributor is fixed on the partition plate and located in the placement chamber, and the input end of the distributor is connected to the pipe mouth on the inner wall of the treatment tank through a pipeline; the spray head is fixed on the partition plate, and the output end is located in the recovery chamber, the spray head is located above the conveying component, and the output end of the distributor is connected to the spray head through a pipeline; thus, the conveying component will rotate the discharge port to discharge the recovered sputum, and it will pass under the spray head during the process. At this time, the distributor adopts an intermittent conveying method to inject the multi-enzyme cleaning agent into the working area through the spray head. Since the working area is moving, the mixing of the multi-enzyme cleaning agent and the sputum is accelerated, the activity of bacteria in the sputum and the viscosity of the sputum are reduced, and the sputum is effectively prevented from adhering to the inner wall of the treatment tank, reducing the subsequent cleaning intensity, and at the same time trying to avoid the sputum from flowing slowly or even being blocked due to its strong viscosity during discharge.

[0010] Furthermore, a feeder and a starter are provided in the fuselage, and a transmission gear set is installed in the fuselage through a bearing; an oil circuit is vertically opened on the inner wall of the treatment tank, the output end of the feeder is connected to the oil circuit pipe mouth through a pipeline, the driving gear of the starter is engaged with the transmission gear set, one end of the rotating support of the conveying component extends into the fuselage and is fixedly connected to the transmission gear set, and the input port of the distributor is connected to the pipeline at the other end of the oil circuit; thus, the starter provides rotational power to the conveying component through the transmission gear set, and a multi-enzyme cleaning agent for treating sputum is stored in the feeder, and the feeder conveys the multi-enzyme cleaning agent to the distributor after passing through the pipeline on the inner wall of the treatment tank.

[0011] Furthermore, the conveying assembly includes a blade-shaped rotor and a rotating shaft. The blade-shaped rotor is sleeved on the rotating shaft. The end of the rotating shaft away from the blade-shaped rotor passes through the bottom of the processing tank and is fixedly connected to the transmission gear set. The rotating shaft is connected to the bottom of the processing tank and the fuselage through a bearing installation; each outer end top of the blade-shaped rotor is provided with an oblique section; thus, the blade-shaped rotor divides the recovery chamber into multiple working areas. As the blade-shaped rotor rotates, the multiple working areas work alternately to complete the movement of sputum in the recovery chamber.

[0012] Furthermore, the sputum suction mechanism includes a sputum suction tube, one end of which passes through the top of the processing tank and is connected to an external sputum suction device through a pipe; the other end of the sputum suction tube is located in the placement cavity, and the end is fixedly connected to a suction assembly, and the suction assembly is composed of a sputum suction cylinder, a plunger, and a return spring; the sputum suction cylinder is fixedly mounted on a partition plate, the plunger is slidably mounted in the sputum suction cylinder, the end of the plunger located outside the sputum suction cylinder is located in the recovery cavity, the return spring is located in the sputum suction cylinder, and is slidably sleeved on the outside of the plunger rod, one end of the return spring is fixedly connected to the bottom of the sputum suction cylinder, and the other end is fixedly connected to the outside of the plunger;

[0013] The suction assembly is located directly above the end of the leaf-shaped rotor, and the end of the plunger located in the recovery chamber is slidably connected to the beveled surface; thus, the leaf-shaped rotor rotates, and the beveled surface of one branch end pushes the plunger to move upward in the suction cylinder. When the plunger is separated from the branch end, the return spring pulls the plunger downward, so that the bottom end of the plunger contacts the beveled surface of the next branch end; the rotation of the conveying assembly provides power for the suction assembly, saving energy while realizing the linkage between the conveying assembly and the suction assembly, avoiding the disconnection between the suction mechanism and the cleaning mechanism.

[0014] Furthermore, there are two of the leaf-shaped rotors and the rotating shaft, and the leaf-shaped rotors correspond to the rotating shafts one by one, and the two leaf-shaped rotors rotate in meshing engagement; thereby, the two leaf-shaped rotors drive the working areas to rotate outward, and through the synchronous and reverse meshing rotation of the two leaf-shaped rotors, the alternation speed between the working areas is accelerated, which facilitates the continuous operation of the subsequent sputum suction mechanism.

[0015] Furthermore, the suction tube is configured to be Y-shaped, and one end of the suction tube located in the placement cavity has two branches; two suction components are provided, and the suction components are connected to the two branches of the suction tube in a one-to-one correspondence; the suction component is located above the two leaf-shaped rotors and on one side of the rotating shaft; the plunger corresponds to the leaf-shaped rotor one-to-one; thus, when the two leaf-shaped rotors rotate synchronously in opposite directions, they respectively push the corresponding plungers to move, so that the two suction components perform alternating suction work, thereby realizing the continuous operation of the suction mechanism and the cleaning mechanism.

[0016] Furthermore, the plunger is provided with a guide channel 1 in the center of the plug head inside the suction cylinder, the guide channel 1 passes through the plug rod of the plunger, and a guide channel 2 is further provided in the plug rod of the plunger, the guide channel 2 is connected with the guide channel 1 and is concentrically arranged; the plunger is located in the recovery chamber and a guide hole is provided on the circumferential outer side of the plug rod, the guide hole passes through the guide channel 2; the diameter of the guide channel 1 is smaller than the diameter of the guide channel 2, a spring 2 is provided in the guide channel 2, one end of the guide channel 2 away from the guide channel 1 is fixedly connected to the spring 2, and the other end of the spring 2 is fixedly connected to the ball 2, the diameter of the ball 2 is larger than the diameter of the guide channel 1 diameter, and is smaller than the diameter of the guide channel 2; thus, when the plunger moves downward, the sputum suction cylinder is in a suction state. At this time, the spring 2 is in a normal state, so that the ball 2 is against the connection between the guide channel 1 and the guide channel 2, thereby achieving the effect of closing the guide channel 2, ensuring that the sputum suction cylinder is in a negative pressure state, which is convenient for the sputum suction tube to perform suction; when the piston moves upward, the ball moves downward under pressure, and the sputum enters the guide channel 2 and enters the recovery chamber from the guide hole. The sputum flows along the oblique section of the flow channel of the plunger rod and finally flows into the working area formed by the leaf-shaped rotor and the processing tank; the rapid conversion between liquid extraction and liquid discharge of the sputum suction cylinder is achieved through an up and down movement process of the plunger, thereby achieving a fast and convenient effect.

[0017] Furthermore, a liquid inlet is provided at the top of the suction cylinder, and the end of the liquid inlet away from the suction cylinder is fixedly connected to the suction tube; a ball is slidably installed in the liquid inlet, and a spring is provided on the outside of the ball, and the other end of the spring is fixedly connected to the inner wall of the suction cylinder; the diameter of the ball is larger than the diameter of the end of the liquid inlet close to the suction tube; thus, when the plunger moves downward, the ball and the spring are affected by the negative pressure and move downward, opening the liquid inlet, and the suction cylinder performs a suction action; when the plunger moves upward, the spring is pushed to drive the ball to press against the liquid inlet, thereby preventing the sputum in the suction cylinder from flowing back.

[0018] Furthermore, a flushing assembly is slidably mounted on the end surface of the partition plate, and the flushing assembly is located on a side of the distributor away from the sputum suction tube;

[0019] The flushing assembly includes an upper plate, a lower plate, a slide rail, and a multi-directional flushing head; the upper plate and the lower plate are fixedly connected by the slide rail, and the slide rail is circumferentially arranged on the side surfaces of the upper plate and the lower plate; the side surfaces of the slide rail are slidably matched with the partition plate; the multi-directional flushing head is vertically fixedly installed on the lower plate, and the multi-directional flushing head is located in the slide rail; a connecting pipe head is provided on the top of the upper plate, one end of the connecting pipe head is connected to the multi-directional flushing head pipeline, and the other end of the connecting pipe head is connected to the distributor pipeline through a pipeline; a push-pull rod is clamped on the top of the upper plate, and the push-pull rod slides away from one end of the upper plate and extends out of the top of the processing tank; thus, when flushing the conveying assembly, the push-pull rod is controlled to move downward, pushing the movable frame formed by the upper plate, the lower plate, and the slide rail to reach between the blade rotors, and the distributor transports the multi-enzyme cleaning liquid to the multi-directional flushing head, and sprays it out from the multi-directional flushing head to flush the working area formed by the blade rotor and the inner wall of the processing tank.

[0020] Furthermore, the supplier includes a liquid tank and a hydraulic pump; the liquid tank is located below the hydraulic pump and is connected through a pipeline; the output end of the hydraulic pump is connected to the oil circuit of the treatment tank through a pipeline; the distributor includes a shell, and an input port is provided on one side of the shell, and the outer end of the input port is connected to the oil circuit pipeline of the treatment tank; two output ports are provided on the side of the shell, one of the output ports is connected to the injection head pipeline, and the other output port is connected to the flushing component pipeline; thus, the hydraulic pump transports the multi-enzyme cleaning liquid in the liquid tank to the distributor; when the sputum suction mechanism is working, the distributor intermittently transports the multi-enzyme cleaning liquid to the injection head for sputum pretreatment; when the sputum suction mechanism stops working and the flushing component is working, the distributor continuously transports the multi-enzyme cleaning liquid to the multi-directional flushing head to flush the working area in multiple directions.

[0021] Furthermore, an electromagnetic reversing valve, an air-controlled one-way valve, a one-way valve 1, a hydraulic-controlled reversing valve, a booster cylinder, a one-way valve 2, a single-rod piston cylinder, and a one-way valve 3 are provided in the shell; the inner end of the input port is connected to the P end of the electromagnetic reversing valve through a pipeline, the A end of the electromagnetic reversing valve is connected to the liquid inlets of the air-controlled one-way valve, the one-way valve 1, and the hydraulic-controlled reversing valve respectively through pipelines, and the B end of the electromagnetic reversing valve is connected to the liquid inlet of the one-way valve 3 through a pipeline; the output end of the air-controlled one-way valve is connected to the inlet end pipeline of the single-rod piston cylinder, and the air pressure port of the air-controlled one-way valve is connected to the outlet end pipeline of the single-rod piston cylinder; another hydraulic port of the hydraulic-controlled reversing valve is connected to the input end pipeline of the electromagnetic reversing valve; the liquid outlet of the one-way valve 2 is connected to the inlet end pipeline of the single-rod piston cylinder;

[0022] A double-piston structure is adopted in the boosting cylinder, and the double piston consists of a piston LP and a piston HP. The end surface area of ​​the piston LP is larger than the end surface area of ​​the piston HP, and the end surface diameter of the cavity where the piston LP is located is larger than the end surface diameter of the cavity where the piston HP is located; the boosting cylinder is respectively provided with a port a, b port, c port, d port, e port, f port, and g port; the output end of the one-way valve one is connected to the a port pipeline of the boosting cylinder, one of the hydraulic ports of the hydraulically controlled reversing valve is connected to the c port pipeline of the boosting cylinder, the liquid inlet of the one-way valve two is connected to the b port pipeline of the boosting cylinder, and the liquid outlet of the one-way valve three is connected to the g port pipeline of the boosting cylinder; the e port of the boosting cylinder is connected to the liquid outlet pipeline of the hydraulically controlled reversing valve, the f port of the boosting cylinder is connected to the output port corresponding to the injection head through a pipeline, and the T end of the electromagnetic reversing valve is connected to the output port corresponding to the flushing component through a pipeline;

[0023] As a result, the electromagnetic reversing valve shifts rightward from the off position and reverses direction, and the multi-enzyme cleaning liquid enters the air-controlled one-way valve, one-way valve 1, and the lower part of the valve core of the hydraulic-controlled reversing valve from the P port respectively; part of the multi-enzyme cleaning liquid passes directly to the rodless cavity of the single-rod piston cylinder through the air-controlled one-way valve, and the remaining multi-enzyme cleaning liquid passes from the one-way valve 1 through the a port to the top of the piston HP in the booster cylinder, pushing the piston HP downward and at the same time entering the rodless cavity of the single-rod piston cylinder from the one-way valve 2, pushing the piston to move, and the gas in the rod cavity of the single-rod piston cylinder enters the air-controlled one-way valve;

[0024] After the piston HP reaches the bottom, the cavity on the top of the piston HP is connected to the upper part of the hydraulically controlled reversing valve core through the C port. The multi-enzyme cleaning liquid in the booster cylinder pushes the hydraulically controlled reversing valve core to move downward and reverse. The hydraulically controlled reversing valve connects the P port of the electromagnetic reversing valve with the bottom of the piston LP. Part of the multi-enzyme cleaning liquid enters the bottom of the piston LP in the booster cylinder and pushes the piston HP upward. The multi-enzyme cleaning liquid in the upper cavity of the piston HP enters the rodless cavity of the single-rod piston cylinder through the one-way valve 2.

[0025] After the piston HP reaches the top, the upper part of the hydraulically controlled reversing valve core is connected to the cavity between the piston HP and the piston LP through the c port, and the multi-enzyme cleaning liquid enters from the lower part of the hydraulically controlled reversing valve core, pushing the valve core to move upward and reverse the connection between the cavity between the piston HP and the piston LP and the bottom of the piston LP; then the multi-enzyme cleaning liquid passes through the a port of the one-way valve 1 and reaches the top of the piston HP in the booster cylinder; the piston LP moves downward and pushes the bottom multi-enzyme cleaning liquid into the cavity between the piston HP and the piston LP, and then is transported to the injection head from the f port of the booster cylinder.

[0026] When the piston in the single-rod piston cylinder reaches the half-chamber position, the pneumatically controlled one-way valve automatically closes due to pressure balance, severing the connection between the single-rod piston cylinder and port P of the solenoid reversing valve. The multi-enzyme cleaning fluid entering from port P flows through the one-way valve and the hydraulically controlled reversing valve into the booster cylinder, pushing pistons HP and LP up and down. This cycle continues, while the distributor intermittently supplies liquid to the spray head and the single-rod piston cylinder is simultaneously filled with liquid.

[0027] Later, when the piston of the single-rod piston cylinder is pushed to the stop position, the rodless chamber of the single-rod piston cylinder quickly rises to the maximum pressure, and the electromagnetic reversing valve returns to the disconnected position; then the suction mechanism is stopped, and the flushing assembly is moved down, the electromagnetic reversing valve is reversed to the left, and the P end of the electromagnetic reversing valve is connected to the B end, and the A end is connected to the T end; the multi-enzyme cleaning liquid enters the booster cylinder through the one-way valve three from the P port of the electromagnetic reversing valve, realizing reverse liquid inflow, and the single-rod piston cylinder begins to unload. The negative pressure in the rod chamber of the single-rod piston cylinder opens the air-controlled one-way valve, and the multi-enzyme cleaning liquid in the rodless chamber of the single-rod piston cylinder flows back to the A end of the electromagnetic reversing valve through the air-controlled one-way valve, and then enters the flushing assembly through the T end of the electromagnetic reversing valve, thereby realizing the continuous flushing of the assembly by the distributor.

[0028] Furthermore, a control panel is provided on the machine body, and the control panel is connected to the electromagnetic reversing valve, the starter, and the hydraulic pump circuit.

[0029] Furthermore, the method for using the cleaning device for the sputum suction device is as follows:

[0030] S1. Connect the end of the suction tube outside the treatment tank to the suction device. Press the start button on the control panel to start the starter, causing the conveying assembly to start rotating and driving the suction assembly to start moving, so that the suction mechanism and the conveying assembly work synchronously;

[0031] S2. Press the pump force button on the control panel to activate the hydraulic pump, causing the supply unit to begin delivering multi-enzyme cleaning solution to the dispenser. Then, press the solenoid valve control button on the control panel to shift the solenoid reversing valve right, opening the P and A terminals. The dispenser now intermittently supplies liquid to the spray head.

[0032] S3. After suctioning is completed, the suction device port draws in an external multi-enzyme cleaning solution. The cleaning solution delivers the remaining sputum in the suction tube and suction cylinder into the recovery chamber. The conveying assembly drives the multi-enzyme cleaning solution to move and clean the inner wall of the treatment tank and the blade rotor.

[0033] S4. Then turn off the starter, control the push-pull rod to move downward, and push the movable frame formed by the upper plate, lower plate, and slide rail to reach the gap between the blade rotor branch end. If the blade rotor branch end is located below the lower plate, the lower plate will slide on the oblique surface when moving downward to push the blade rotor to rotate; then, the control panel controls the electromagnetic reversing valve to move left and open, so that the P end is connected to the B end; the distributor continuously transports the multi-enzyme cleaning solution to the multi-directional flushing head, and sprays it out from the multi-directional flushing head to flush the working area formed by the blade rotor and the inner wall of the treatment tank.

[0034] The beneficial effects of the present application are as follows: the present application provides a cleaning device for a sputum suction device, which is equipped with a sputum suction mechanism and a cleaning mechanism. The sputum sucked by the sputum suction mechanism is placed in a recovery cavity, and the cleaning mechanism processes the sputum to provide a temporary storage space for the subsequent sputum suction action; the cleaning mechanism and the sputum suction mechanism work in separate areas, achieving the effect of continuous sputum suction without stopping for cleaning; in addition, the rotation of the conveying component provides power for the suction component, saving energy while realizing the linkage between the conveying component and the suction component, avoiding the disconnection between the sputum suction mechanism and the cleaning mechanism.

[0035] In addition to the above-described purposes, features and advantages, the present application also has other purposes, features and advantages. The present application will be further described in detail below with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0051] like Figures 1-10 As shown, the present application provides a cleaning device for a sputum suction device, which is used in medical sputum suction, referring to Figures 1-4 , comprises a body 1, a processing tank 2, a sputum suction mechanism, and a cleaning mechanism; the processing tank 2 is fixedly mounted on the body 1, the sputum suction mechanism and the cleaning mechanism are arranged in the processing tank 2, and the input end of the sputum suction mechanism extends out of the top of the processing tank 2; a partition plate 21 is fixedly mounted inside the processing tank 2, and the partition plate 21 divides the inner cavity of the processing tank 2 into a placement chamber 22 and a recovery chamber 23; the sputum suction mechanism is located in the placement chamber 22, and the output end passes through the partition plate 21 and is communicated with the recovery chamber 23, and a guide port 202 is provided at the bottom of the recovery chamber 23, and the port of the guide port 202 is connected to the external recovery bin through a pipeline; the cleaning mechanism comprises a conveying assembly 26, a distributor 27, and a spray head 28; thus, the sputum sucked by the sputum suction mechanism is placed in the recovery chamber 23, and the cleaning mechanism processes the sputum to provide a temporary storage space for the subsequent sputum suction action; the cleaning mechanism and the sputum suction mechanism are divided into work zones, so that the effect of continuous sputum suction can be achieved without stopping the machine for cleaning;

[0052] A feeder 11 and a starter 12 are provided in the fuselage 1, and a transmission gear set 13 is installed in the fuselage 1 through a bearing; an oil circuit 201 is vertically opened on the inner wall of the treatment tank 2, and the output end of the feeder 11 is connected to the pipe mouth of the oil circuit 201 through a pipe, and the pipe is wrapped around the outer shell of the starter 12, which has a cooling effect on the starter 12. At the same time, the heated multi-enzyme cleaning liquid can reduce the viscosity of the sputum after mixing with the sputum; the driving gear of the starter 12 is engaged with the transmission gear set 13, and one end of the rotating support of the conveying component 26 extends into the fuselage 1 and is fixedly connected to the transmission gear set 13, and the input port of the distributor 27 is connected to the other end of the oil circuit 201 through the pipe; thus, the starter 12 provides rotational power to the conveying component 26 through the transmission gear set 13, and the multi-enzyme cleaning agent for treating sputum is stored in the feeder 11. The feeder 11 conveys the multi-enzyme cleaning agent to the distributor 27 after passing through the pipe on the inner wall of the treatment tank 2.

[0053] Reference Figure 4 、 Figure 5, the conveying assembly 26 is rotatably installed in the recovery chamber 23; the distributor 27 is fixed on the partition plate 21 and is located in the placement chamber 22, and the input end of the distributor 27 is connected to the pipe opening on the inner wall of the processing tank 2 through a pipeline; the injection head 28 is fixed on the partition plate 21, and the output end is located in the recovery chamber 23, the injection head 28 is located above the conveying assembly 26, and the output end of the distributor 27 is connected to the injection head 28 through a pipeline; thus, the conveying assembly 26 rotates the discharge port to discharge the recovered sputum, and it will pass under the injection head 28 during the process. At this time, the distributor 27 adopts an intermittent conveying method to inject the multi-enzyme cleaning agent into the working area through the injection head 28. Since the working area is moving, the mixing of the multi-enzyme cleaning agent and the sputum is accelerated, the activity of bacteria in the sputum and the viscosity of the sputum are reduced, and the sputum is effectively prevented from adhering to the inner wall of the processing tank 2, reducing the subsequent cleaning intensity, and at the same time trying to avoid the sputum from flowing slowly or even being blocked due to its strong viscosity when being discharged.

[0054] Among them: reference Figure 4 The conveying assembly 26 includes a lobe rotor 261 and a rotating shaft 262. The lobe rotor 261 is sleeved on the rotating shaft 262. The end of the rotating shaft 262 away from the lobe rotor 261 passes through the bottom of the processing tank 2 and is fixedly connected to the transmission gear set.

There are two lobe rotors 261 and two rotating shafts 262, and the lobe rotors 261 correspond to the rotating shafts 262 one by one. The two lobe rotors 261 are engaged and rotated ( Figure 4 The middle arrow indicates the rotation direction of the lobe rotor 261); thus, the lobe rotor 261 divides the recovery chamber 23 into multiple working areas. The two lobe rotors 261 drive the working areas to rotate outward. Through the synchronous and counter-meshing rotation of the two lobe rotors 261, the alternation speed between the working areas is accelerated, the movement of sputum in the recovery chamber 23 is completed, and the storage pressure of the processing tank 2 is reduced.

[0055] Reference Figure 3-Figure 6 The sputum suction mechanism includes a sputum suction tube 24, one end of which passes through the top of the treatment tank 2 and is connected to an external sputum suction device through a pipe; the other end of the sputum suction tube 24 is located in the placement cavity 22, and the end is fixedly connected to a suction component 25, which is composed of a sputum suction cylinder 251, a plunger 252, and a return spring 253 (such as Figure 6 ), the suction cylinder 251 is fixedly mounted on the partition plate 21, the plunger 252 is slidably mounted in the suction cylinder 251, one end of the plunger 252 located outside the suction cylinder 251 is located in the recovery chamber 23, the return spring 253 is located in the suction cylinder 251 and slidably sleeved outside the plug rod of the plunger 252, one end of the return spring 253 is fixedly connected to the bottom of the suction cylinder 251, and the other end is fixedly connected to the outside of the plunger 252;

[0056] Reference Figure 4 、 Figure 5 The suction assembly 25 is located above the end of the blade rotor 261 (on the side of the rotating shaft 262 away from the outlet 202), and the end of the plunger 252 located in the recovery chamber 23 is slidably connected to the bevel 2611; in order to adapt to the two blade rotors 261, the sputum suction tube 24 is configured to be Y-shaped, and two suction assemblies 25 are provided; Figure 5 , one end of the suction tube 24 located in the placement cavity 22 is divided into two branches, and the suction assembly 25 is connected to the two branches of the suction tube 24 in a one-to-one correspondence; the suction assembly 25 is located above the two leaf-shaped rotors 261 and on one side of the rotating shaft 262; the plunger 252 corresponds to the leaf-shaped rotor 261 in a one-to-one correspondence; thus, when the two leaf-shaped rotors 261 rotate synchronously in opposite directions, the corresponding oblique section 2611 of the leaf-shaped rotor 261 pushes the plunger 252 to move upward in the suction cylinder 251, and when the plunger 252 is separated from the branch end, the return spring 253 pulls the plunger 252 downward, so that the bottom end of the plunger 252 is aligned with the oblique section 261 of the next branch end The oblique section 2611 of the blade-shaped rotor 261 that contacts the corresponding one pushes the plunger 252 to move upward in the suction cylinder 251. When the plunger 252 is separated from the branch end, the return spring 253 pulls the plunger 252 downward, so that the bottom end of the plunger 252 contacts the oblique section 2611 of the next branch end; thereby, the rotation of the conveying component 26 provides power for the suction component 25, saving energy while realizing the linkage between the conveying component 26 and the suction component 25, and avoiding the disconnection of the sputum suction mechanism and the cleaning mechanism; the two blade-shaped rotors 261 enable the two suction components 25 to perform alternate suction work, thereby ensuring that the sputum suction mechanism and the cleaning mechanism can work continuously.

[0057] Reference Figure 6The plunger 252 is located in the center of the plug head of the suction cylinder 251 and is provided with a guide channel 1 2521. The guide channel 1 2521 passes through the plug rod of the plunger 252. The plug rod of the plunger 252 is also provided with a guide channel 2522. The guide channel 2522 is connected to the guide channel 1 2521 and is concentrically arranged. The plunger 252 is located in the recovery chamber 23 and is provided with a guide hole 2523 on the circumferential outer side of the plug rod. The guide hole 2523 is provided on the outer side of the plug rod. 23 is connected to the guide channel 2522; the diameter of the guide channel 1 2521 is smaller than the diameter of the guide channel 2 2522, and a spring 2525 is provided in the guide channel 2 2522. The end of the guide channel 2 2522 away from the guide channel 1 2521 is fixedly connected to the spring 2525, and the other end of the spring 2525 is fixedly connected to the ball 2524, and the diameter of the ball 2524 is larger than that of the guide channel 1 2521. The diameter of the guide channel 2522 is smaller than that of the second guide channel 2522; thus, when the plunger 252 moves downward, the sputum suction cylinder 251 is in the suction state. At this time, the spring 2525 is in the normal state, so that the ball 2524 is against the connection between the guide channel 1 2521 and the guide channel 2 2522, achieving the effect of closing the guide channel 2 2522, ensuring that the sputum suction cylinder 251 is in a negative pressure state, which is convenient for the sputum suction tube 24 to perform suction; when the piston moves upward, the ball moves downward under pressure, and the sputum enters the guide channel 2 2522 and enters the recovery chamber 23 from the guide hole 2523. The sputum flows along the oblique section 2611 of the plunger 252 plug rod and finally flows into the working area formed by the leaf rotor 261 and the processing tank 2; the plunger 252 moves back and forth up and down to achieve a rapid conversion between liquid extraction and liquid discharge in the sputum suction cylinder 251, achieving a fast and convenient effect.

[0058] Reference Figure 6 A liquid inlet is provided at the top of the suction cylinder 251, and the end of the liquid inlet away from the suction cylinder 251 is fixedly connected to the suction tube 24; in order to prevent the sputum in the suction cylinder 251 from flowing back: a ball 2511 is slidably installed in the liquid inlet, and a spring 2512 is provided on the outer surface of the ball 2511, and the other end of the spring 2512 is fixedly connected to the inner wall of the suction cylinder 251; the diameter of the ball 2511 is larger than the diameter of the end of the liquid inlet close to the suction tube 24; therefore, when the plunger 252 moves downward, the ball 2511 and the spring 2512 move downward under the influence of negative pressure, opening the liquid inlet, and the suction cylinder 251 performs a suction action; when the plunger 252 moves upward, the spring 2512 is pushed to drive the ball 2511 against the liquid inlet.

[0059] In addition: See Figure 3-4 、 Figure 7-9 The end surface of the partition plate 21 is slidably mounted with a flushing assembly 29 for cleaning the recovery cavity after surgery. The flushing assembly 29 is located on the side of the distributor 27 away from the sputum suction tube 24;

[0060] Reference Figure 7 、 Figure 9The flushing assembly 29 includes an upper plate 291, a lower plate 292, a slide rail 293, and a multi-directional flushing head 294; the upper plate 291 and the lower plate 292 are fixedly connected by the slide rail 293, and the slide rail 293 is circumferentially arranged on the side of the upper plate 291 and the lower plate 292; the side of the slide rail 293 is slidably matched with the partition plate 21; the multi-directional flushing head 294 is vertically fixedly installed on the lower plate 292, and the multi-directional flushing head 294 is located in the slide rail 293; a connecting pipe head 295 is provided on the top of the upper plate 291, one end of the connecting pipe head 295 is connected to the multi-directional flushing head 294 pipeline, and the other end of the connecting pipe head 295 is connected to the distributor 27 pipeline through a pipeline (refer to Figure 9 ); A push-pull rod 296 is clamped on the top of the upper plate 291, and the end of the push-pull rod 296 away from the upper plate 291 slides out of the top of the processing tank 2; therefore, when flushing the conveying assembly 26, the push-pull rod 296 is controlled to move downward, pushing the movable frame formed by the upper plate 291, the lower plate 292, and the slide rail 293 to reach between the blade rotors 261, and the distributor 27 conveys the multi-enzyme cleaning liquid to the multi-directional flushing head 294, and the multi-directional flushing head 294 sprays it to flush the working area formed by the blade rotor 261 and the inner wall of the processing tank 2.

[0061] Reference Figure 9-10 , the liquid supply system of the cleaning mechanism is as follows:

[0062] Among them, such as Figure 9 The supplier 11 includes a liquid tank 111 and a hydraulic pump 112; the liquid tank 111 is located below the hydraulic pump 112 and is connected by a pipeline; the output end of the hydraulic pump 112 is connected to the oil circuit 201 of the treatment tank 2 through a pipeline; the distributor 27 includes a shell, and an input port is provided on one side of the shell, and the outer end of the input port is connected to the oil circuit 201 of the treatment tank 2; two output ports are provided on the side of the shell, one of which is connected to the injection head 28 pipeline, and the other is connected to the flushing component 29 pipeline; thus, the hydraulic pump 112 transports the multi-enzyme cleaning liquid in the liquid tank 111 to the distributor 27; when the sputum suction mechanism is working, the distributor 27 intermittently transports the multi-enzyme cleaning liquid to the injection head 28 for sputum pretreatment; when the sputum suction mechanism stops working and the flushing component 29 is working, the distributor 27 continuously transports the multi-enzyme cleaning liquid to the multi-directional flushing head 294 to flush the working area in multiple directions.

[0063] Reference Figure 10In order to realize the regulation of intermittent and continuous liquid supply of the distributor, the shell is provided with an electromagnetic reversing valve 271, an air-controlled one-way valve 272, a one-way valve 273, a hydraulic-controlled reversing valve 274, a booster cylinder 275, a one-way valve 276, a single-rod piston cylinder 277, and a one-way valve 3 278; the inner end of the input port is connected to the P end of the electromagnetic reversing valve 271 through a pipeline, and the A end of the electromagnetic reversing valve 271 is connected to the air-controlled one-way valve 272, the one-way valve 273, the hydraulic-controlled reversing valve 27 through pipelines. 4, the B end of the electromagnetic reversing valve 271 is connected to the liquid inlet of the check valve 3 278 through a pipeline; the output end of the air-controlled check valve 272 is connected to the inlet end pipeline of the single-rod piston cylinder 277, and the air pressure port of the air-controlled check valve 272 is connected to the outlet end pipeline of the single-rod piston cylinder 277; the other hydraulic port of the hydraulic reversing valve 274 is connected to the input end pipeline of the electromagnetic reversing valve 271; the liquid outlet of the second check valve 276 is connected to the inlet end pipeline of the single-rod piston cylinder 277;

[0064] Among them: the booster cylinder 275 adopts a double piston structure, which consists of a piston LP and a piston HP. The end surface area of ​​the piston LP is larger than the end surface area of ​​the piston HP, and the end surface diameter of the cavity where the piston LP is located is larger than the end surface diameter of the cavity where the piston HP is located; the booster cylinder 275 is respectively provided with a port a, a port b, a port c, a port d, a port e, a port f, and a port g; the output end of the one-way valve 273 is connected to the port a pipeline of the booster cylinder 275, and one of the hydraulic control reversing valves 274 is connected to the one-way valve 273. The first hydraulic port is connected to the c port pipeline of the boosting cylinder 275, the liquid inlet of the second one-way valve 276 is connected to the b port pipeline of the boosting cylinder 275, and the liquid outlet of the third one-way valve 278 is connected to the g port pipeline of the boosting cylinder 275; the e port of the boosting cylinder 275 is connected to the liquid outlet pipeline of the hydraulic control reversing valve 274, the f port of the boosting cylinder 275 is connected to the corresponding output port of the injection head 28 through a pipeline, and the T end of the electromagnetic reversing valve 271 is connected to the corresponding output port of the flushing component 29 through a pipeline;

[0065] As a result, the electromagnetic reversing valve 271 is shifted to the right from the disconnected position, and the multi-enzyme cleaning liquid enters the air-controlled one-way valve 272, the one-way valve 1 273, and the lower part of the valve core of the hydraulic-controlled reversing valve 274 from the P port respectively; part of the multi-enzyme cleaning liquid passes through the air-controlled one-way valve 272 directly to the rodless cavity of the single-rod piston cylinder 277, and the remaining multi-enzyme cleaning liquid passes through the one-way valve 1 273 through the a port to the top of the piston HP in the booster cylinder 275, pushing the piston HP downward and at the same time passing through the one-way valve 2 276 to the rodless cavity of the single-rod piston cylinder 277, pushing the piston to move, and the gas in the rod cavity of the single-rod piston cylinder 277 enters the air-controlled one-way valve 272;

[0066] After the piston HP reaches the bottom, the top cavity of the piston HP is connected to the upper part of the hydraulic control reversing valve 274 core through the C port, and the multi-enzyme cleaning liquid in the booster cylinder 275 pushes the hydraulic control reversing valve 274 core to move downward and reverse. The hydraulic control reversing valve 274 connects the P port of the electromagnetic reversing valve 271 with the bottom of the piston LP. Part of the multi-enzyme cleaning liquid enters the bottom of the piston LP in the booster cylinder 275 and pushes the piston HP upward. The multi-enzyme cleaning liquid in the upper cavity of the piston HP passes through the one-way valve 276 and enters the rodless cavity of the single-rod piston cylinder 277.

[0067] After the piston HP reaches the top, the upper part of the hydraulically controlled reversing valve 274 core is connected to the cavity between the piston HP and the piston LP through the c port, and the multi-enzyme cleaning liquid enters from the lower part of the hydraulically controlled reversing valve 274 core, pushing the valve core to move upward and reverse the connection between the cavity between the piston HP and the piston LP and the bottom of the piston LP; then the multi-enzyme cleaning liquid reaches the top of the piston HP in the boosting cylinder 275 from the one-way valve 273 through the a port; the piston LP moves downward to push the bottom multi-enzyme cleaning liquid into the cavity between the piston HP and the piston LP, and then is transported to the injection head 28 from the f port of the boosting cylinder 275.

[0068] When the piston in single-rod piston cylinder 277 reaches the half-chamber position, pneumatically controlled check valve 272 automatically closes due to pressure balance, severing the connection between single-rod piston cylinder 277 and port P of electromagnetic reversing valve 271. The multi-enzyme cleaning solution, entering from port P, passes through check valve 1 273 and hydraulically controlled reversing valve 274 into booster cylinder 275, pushing pistons HP and LP up and down. This cycle continues, providing intermittent liquid supply from distributor 27 to spray head 28 while simultaneously filling single-rod piston cylinder 277.

[0069] Later, when the piston of the single-rod piston cylinder 277 is pushed to the stop position, the rodless chamber of the single-rod piston cylinder 277 quickly rises to the maximum pressure, and the electromagnetic reversing valve 271 returns to the disconnected position; then the sputum suction mechanism is stopped, and the flushing assembly 29 is moved down, the electromagnetic reversing valve 271 is shifted to the left and reversed, the P end of the electromagnetic reversing valve 271 is connected to the B end, and the A end is connected to the T end; the multi-enzyme cleaning liquid enters the P port of the electromagnetic reversing valve 271 and enters the boosting cylinder 275 through the one-way valve 3 278, realizing reverse liquid inflow, and the single-rod piston cylinder 277 begins to unload. The negative pressure in the rod chamber of the single-rod piston cylinder 277 opens the air-controlled one-way valve 272, and the multi-enzyme cleaning liquid in the rodless chamber of the single-rod piston cylinder 277 flows back to the A end of the electromagnetic reversing valve 271 through the air-controlled one-way valve 272, and then enters the flushing assembly 29 through the T end of the electromagnetic reversing valve 271, thereby realizing the continuous flushing of the flushing assembly 29 by the distributor 27.

[0070] In addition, a control panel is provided on the fuselage 1 , and the control panel is connected to the electromagnetic reversing valve 271 , the starter, and the hydraulic pump 112 .

[0071] The method of using the cleaning device for the above-mentioned sputum suction device is as follows:

[0072] S1. Connect one end of the suction tube 24 outside the treatment tank 2 to the suction device, press the start button on the control panel, start the starter 12, so that the conveying assembly 26 begins to rotate, and drives the suction assembly 25 to start moving, so that the suction mechanism and the conveying assembly 26 work synchronously;

[0073] S2. Press the pump force button on the control panel of body 1 to start hydraulic pump 112, causing feeder 11 to begin delivering multi-enzyme cleaning solution to dispenser 27. Then, press the solenoid valve control button on the control panel to control solenoid reversing valve 271 to move right and open, connecting terminal P with terminal A. At this point, dispenser 27 intermittently supplies liquid to spray head 28.

[0074] S3. After suctioning, the suction device port is sucked into the external multi-enzyme cleaning solution; cleaning solution suction tube 24, the residual sputum in the suction cylinder 251 is sent to the recovery chamber 23; the delivery assembly 26 drives the multi-enzyme cleaning solution to move and clean the inner wall of the treatment tank 2 and the blade rotor 261;

[0075] S4. Then turn off the starter 12, control the push-pull rod 296 to move downward, and push the movable frame formed by the upper plate 291, the lower plate 292, and the slide rail 293 to reach the gap between the branch ends of the lobe rotor 261. If the branch end of the lobe rotor 261 is located below the lower plate 292, the lower plate 292 slides on the bevel 2611 when moving downward to push the lobe rotor 261 to rotate; then, the control panel controls the electromagnetic reversing valve 271 to move left and open, so that the P end is connected to the B end; the distributor 27 continuously transports the multi-enzyme cleaning solution to the multi-directional flushing head 294, and sprays it out from the multi-directional flushing head 294 to flush the working area formed by the lobe rotor 261 and the inner wall of the treatment tank 2.
