Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly, to a constant-temperature portable automatic rectal fixed-point irrigator and its usage method. Background Art

[0002] Rectal fixed-point irrigation refers to delivering the irrigation fluid precisely to a specified position within the rectum through specific equipment or methods to remove residues, bacteria, toxins, etc. within the rectum, thereby achieving the purpose of disease prevention, adjuvant therapy, or preoperative preparation. For example, in rectal cancer surgery, rectal fixed-point irrigation is used as an important means to reduce residual tumor cells in the intestinal lumen. By closing the intestinal lumen before transecting the distal intestinal tube and performing sufficient anal dilation and irrigation, the local recurrence rate after surgery can be effectively reduced.

[0003] In the field of existing rectal irrigation devices, although many products have made significant progress in design, there are still some deficiencies. Firstly, regarding the stability of the connection of the liquid inlet and outlet pipelines, the stability of traditional quick-connection methods is average, with a potential risk of loosening, while threaded connections are relatively troublesome and cannot meet practical needs. Secondly, regarding the portability of the device, some of the current market irrigation devices are designed relatively bulky, which greatly limits their usage scenarios and portability. These bulky irrigation devices often have a large volume and a non-negligible weight, making it inconvenient for patients or medical staff to carry and move them. For example, when going out or performing home care, bulky irrigation devices not only increase the burden of carrying but may also affect the timeliness and continuity of use due to lack of portability. In addition, the bulky design of these devices may also have a negative impact on their operational convenience. The complex structure and heavy weight may lead to inflexible operation during use, thereby affecting the accuracy of irrigation and the comfort of patients, and the operation difficulty is high, making it inconvenient for different groups of people to use.

[0004] Therefore, there is a particular need to design a constant-temperature portable automatic rectal fixed-point irrigator and its usage method to solve the above technical problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a constant-temperature portable automatic rectal fixed-point irrigator and its usage method to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides a constant-temperature portable automatic rectal fixed-point irrigator, including a body. The upper end of the body is provided with a liquid inlet pipe, and the lower end is provided with a liquid outlet pipe. Plastic conduits with a square appearance design are inserted on both the liquid inlet and outlet pipes. The plastic conduits can be connected to a washing medicine bag or a rinsing head / anal tube, and the plastic conduits are connected to locking components designed at the upper and lower ends of the body.

[0007] The locking component includes a housing fixed to the upper and lower ends of the body. Inside the housing, a central column is installed. A ring plate is rotatably installed outside the central column. The outer wall of the ring plate is provided with annularly distributed tooth tracks, and one side of the ring plate passes through the opening of the housing. The tooth track on the outer wall of the ring plate meshes with the tooth track on the side end of the plastic conduit. A limiting rod is rotatably installed in the recesses at the upper and lower ends of the central column. The limiting rod is butted against a spring in the recess, and the limiting rod is stuck in the grooves on the inner wall of the ring plate, and the grooves are evenly distributed on the inner wall of the ring plate. And at this time, the limiting rod rotates outwards to the maximum amplitude;

[0008] Inside the body, there is a module component for the transportation, reflux and heating of the flushing liquid.

[0009] Preferably, annular grooves are provided on both sides of the ring plate, and annular sliders slide inside the grooves. The annular sliders are fixed to the side wall of the fitting plate. The fitting plate is also annularly designed. The fitting plate fits against the side wall of the ring plate and is fixed to the inner side of the housing by thin rods.

[0010] Preferably, the central column is penetrated by a hollow tube. One end of the hollow tube contacts the inner wall of the housing, and the other end is connected to a spring on the inner wall of the housing.

[0011] Preferably, the hollow tube is penetrated by a fixing rod. Grooves are provided at the upper and lower ends of the fixing rod, and two insertion blocks fixed to the inner wall of the hollow tube are inserted to form a sliding connection. Two guiding pull rods are provided on the fitting surface of the hollow tube and the housing, and pull rings are provided at the outer ends of the guiding pull rods.

[0012] Preferably, the module component is composed of a peristaltic metering pump, a control circuit board, a solenoid valve, a quick-change silicone tube, a quick-change manifold plate, a liquid level detection sensor, a constant temperature module, and a stepless voltage regulation module. The quick-change manifold plate is docked with the liquid inlet pipe of the body, and a solenoid valve is provided at the outlet of the quick-change manifold plate. The solenoid valve, the peristaltic metering pump and the liquid outlet pipe of the body are docked through a quick-change silicone tube.

[0013] Preferably, a charging cable is provided on the side wall of the body, and one end of the charging cable is docked with an external mobile power supply.

[0014] Preferably, on the front of the body, there are a stepless flow and pressure regulation knob, a plugging expansion open button, a plugging expansion close button, a flushing switch open button, a flushing switch close button and a power on / off key. The stepless flow and pressure regulation knob is used to control the operation of the stepless voltage regulation module. The plugging expansion open button and the plugging expansion close button are used to control the expansion of the cleaning liquid outlet pipe. The flushing switch open button and the flushing switch close button are used to control the on / off of the peristaltic metering pump.

[0015] Preferably, a liquid level detection sensor and a constant temperature module are also installed on the quick-change manifold plate. The stepless voltage regulation module is docked with the peristaltic metering pump, and the control circuit board is used to control each electronic module of the module component.

[0016] Preferably, the rear cover of the body is detachably installed for removing the quick-change silicone tube and the quick-change manifold plate.

[0017] The present invention also provides a method for using a constant-temperature portable automatic rectal fixed-point irrigator, which includes the following steps:

[0018] S1: Device assembly and connection:

[0019] First, the user connects the washing medicine bag or the irrigation head / anal tube to the liquid inlet pipe at the upper end and the liquid outlet pipe at the lower end of the body through a plastic catheter. The plastic catheter cooperates with the locking components at the upper and lower ends of the body. The tooth track on the outer wall of the ring plate meshes with the tooth track on the side end of the plastic catheter to achieve a stable connection. At the same time, under the action of the notch docking spring, the limiting rod is stuck in the groove on the inner wall of the ring plate to prevent the ring plate from rotating randomly, thereby ensuring the stability of the connection.

[0020] S2: Flushing liquid delivery and adjustment:

[0021] When the user presses the flushing switch on button, the control circuit board receives the signal and starts the peristaltic metering pump. The peristaltic metering pump starts to work, extracts the flushing liquid from the washing medicine bag through the quick-change silicone tube at the quick-change manifold plate, and transports it to the liquid outlet pipe inside the body. The user can adjust the output pressure of the stepless pressure regulation module through the stepless flow pressure adjustment knob, thereby controlling the delivery speed and pressure of the peristaltic metering pump to achieve precise adjustment of the flushing liquid.

[0022] S3: Constant temperature and liquid level detection:

[0023] The constant temperature module continuously monitors the temperature of the flushing liquid and heats or keeps it warm according to the preset value to ensure that the flushing liquid remains within a suitable constant temperature range. The liquid level detection sensor is installed on the quick-change manifold plate to detect the liquid level of the flushing liquid. When the liquid level is lower than the preset value, the sensor sends a signal to the control circuit board to remind the user to replenish the flushing liquid in time.

[0024] S4: Control of the expansion of the cleaning liquid outlet pipe:

[0025] The user can control the expansion state of the cleaning liquid outlet pipe through the plugging expansion open button and the plugging expansion close button. When it is necessary to increase the flushing pressure, the plugging expansion open button can be opened to expand the liquid outlet pipe, thereby increasing the flushing effect. After the flushing is completed, press the plugging expansion close button to restore the liquid outlet pipe to its original state.

[0026] S5: Maintenance and cleaning:

[0027] The cover on the back of the body is of a detachable design, and the user can open the cover at any time to take out the quick-change silicone tube and the quick-change manifold plate for replacement to ensure the hygiene and performance of the device.

[0028] The beneficial effects of the present invention are:

[0029] 1. In order to achieve cleanliness and repeated use of the instrument, all parts that come into direct contact with the liquid are of disposable quick-change type. The instrument is small in size and light in weight, suitable for clinical use in hospitals, home use and portable use in travel. The external power supply is rich in adaptability, and a compatible power supply can be found in basically all kinds of occasions. The flow rate is infinitely adjustable, and it is suitable for men, women, young and old, and all kinds of races. At the same time, the operation is simple and easy to use, and it can be used simply by reading the instructions. The configuration of the expansion anal tube can be used for fixed-point flushing, and accidents can be eliminated. It is low-voltage driven and controlled, and has liquid level detection protection to prevent air from filling into the intestine. Finally, it has a liquid constant temperature heating function to maximize the comfort in all seasons, and can use different efficacy liquid medicines, which can have both flushing and treatment functions.

[0030] 2. The present invention further improves the safety and convenience of the instrument through the design of the locking component. The locking component not only ensures that the parts in direct contact with the liquid (such as plastic catheters, quick-change silicone tubes, etc.) can be firmly connected to the body to prevent contamination and damage caused by accidental falling off or leakage during the flushing process, but also enables these parts to be easily and quickly replaced, thereby meeting the requirements of repeated use and cleanliness of the instrument.

[0042] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0043] As Figures 1 - 8As shown in the figure, a constant-temperature portable automatic rectal fixed-point rinser and its usage method of the present invention include a body 1. A charging cable 12 is provided on the side wall of the body 1. One end of the charging cable 12 is docked with an external mobile power supply 13. A liquid inlet pipe is provided at the upper end of the body 1 and a liquid outlet pipe is provided at the lower end. Plastic conduits 2 with a square appearance design are inserted on both the inlet and outlet pipes. The plastic conduit 2 is either docked with a washing medicine bag or docked with a rinsing head / anorectal tube. The plastic conduit 2 is docked with a locking component 3 designed at the upper and lower ends of the body 1. The locking component 3 includes a housing 31 fixed at the upper and lower ends of the body 1. A central column 32 is installed inside the housing 31. A ring plate 33 is rotatably installed outside the central column 32. The outer wall of the ring plate 33 is provided with a circumferentially distributed tooth track, and one side of the ring plate 33 passes through the opening of the housing 31. The tooth track on the outer wall of the ring plate 33 meshes with the tooth track on the side end of the plastic conduit 2. A limiting rod 35 is rotatably installed in the concave openings at the upper and lower ends of the central column 32. The limiting rod 35 is docked with a spring 34 in the concave opening. The limiting rod 35 is stuck in the groove on the inner wall of the ring plate 33, and the grooves are evenly distributed on the inner wall of the ring plate 33. And at this time, the limiting rod 35 rotates outwards to the maximum amplitude. A module component 4 is provided inside the body 1 for the transportation, reflux, and heating of the rinsing liquid. Both sides of the ring plate 33 are provided with annular grooves, and an annular slider 37 slides inside the grooves. The annular slider 37 is fixed on the side wall of a fitting plate 36. The fitting plate 36 is also annularly designed. The fitting plate 36 is attached to the side wall of the ring plate 33 and is fixed inside the housing 31 by a thin rod. The central column 32 is penetrated by a hollow tube 39. One end of the hollow tube 39 contacts the inner wall of the housing 31, and the other end is connected to a spring 310 on the inner wall of the housing 31. The hollow tube 39 is penetrated by a fixing rod 38. The upper and lower ends of the fixing rod 38 have grooves, and two insertion blocks 311 fixed on the inner wall of the hollow tube 39 are inserted to form a sliding connection. Two guiding pull rods 312 are provided on the fitting surface of the hollow tube 39 and the housing 31. A pull ring is provided at the outer end of the guiding pull rod 312.

[0044] As described above, through the design of the locking component 3, during operation, first, the charging cable 12 is plugged into and connected to the external mobile power supply 13. Then, it is necessary to connect the washing potion bag or the rinsing head / anal tube to the liquid inlet pipe at the upper end and the liquid outlet pipe at the lower end of the machine body 1. Since the tube head of the plastic catheter 2 of the washing potion bag or the rinsing head / anal tube is square-shaped, during the socketing process, the tooth track on the side of the plastic catheter 2 contacts the tooth track on the outer wall of the ring plate 33, driving it to rotate between the annular sliders 37 on the inner sides of the two fitting plates 36. The limiting rod 35 rotates into the notch inside the central column 32 due to the extrusion of the inner wall groove of the ring plate 33 until it moves to the next groove of the ring plate 33 and is ejected by the spring 310. When the socketing is completed, the limiting rod 35 just gets stuck in the groove of the ring plate 33. Due to the inclined notch design of the groove and the fact that the limiting rod 35 rotates outwards to the maximum extent at this time, the ring plate 33 cannot rotate at this time, which forms a firm connection between the plastic catheter 2 and the machine body 1, avoiding the risk of catheter detachment caused by accidental touch or pressure during use. In addition, this locking mechanism is not only simple and easy to use, but also provides good sealing performance through the mutual engagement of the tooth track and the groove, effectively preventing the leakage of the rinsing liquid during transmission and ensuring the hygiene and safety of the rinsing process;

[0045] Secondly, when the user needs to disconnect the plastic catheter 2 from the machine body 1, just gently hold the pull ring and apply a thrust, and the guiding pull rod 312 will drive the hollow tube 39 to slide along the fixed rod 38, while compressing the connecting spring 310. This action will cause the limiting rod 35 to disengage from the groove of the ring plate 33, releasing the locked state of the ring plate 33, allowing the user to easily rotate and pull out the plastic catheter 2. This design not only simplifies the disassembly process but also avoids damage that may be caused by forced tube pulling, improving the durability of the product and the user experience.

[0046] The module component 4 is composed of a peristaltic metering pump 43, a control circuit board 45, a solenoid valve 49, a quick-change silicone tube 42, a quick-change manifold 41, a liquid level detection sensor 47, a constant temperature module 48, and a stepless voltage regulation module 410 installed inside the machine body 1. The quick-change manifold 41 is docked with the liquid inlet pipe of the machine body 1, and there is a solenoid valve 49 at the outlet of the quick-change manifold 41. The solenoid valve 49, the peristaltic metering pump 43, and the liquid outlet pipe of the machine body 1 are docked through the quick-change silicone tube 42. A liquid level detection sensor 47 and a constant temperature module 48 are also installed on the quick-change manifold 41. The stepless voltage regulation module 410 is docked with the peristaltic metering pump 43, and the control circuit board 45 is used to control each electronic module of the module component 4.

[0047] As described above, through the design of the module assembly 4, the peristaltic metering pump 43 is the core component for flushing fluid delivery. It pumps the flushing fluid by periodically squeezing a hose (in this design, it is the quick-change silicone hose 42). The design of this pump allows for precise control of the flushing fluid flow without leakage. The rotation speed and squeezing degree of the peristaltic metering pump 43 can be finely adjusted by the control circuit board 45 through the stepless voltage regulation module 410 to meet different flushing requirements. The control circuit board 45 is the "brain" of the entire flusher. It is responsible for receiving instructions from the user interface and controlling the operation of all electronic modules in the module assembly 4. This includes starting and stopping the peristaltic metering pump 43, switching the solenoid valve 49, setting the temperature of the constant temperature module 48, and reading the data of the liquid level detection sensor 47. The control circuit board 45 is also responsible for processing these data to achieve an intelligent flushing process. The solenoid valve 49 is installed at the outlet of the quick-change manifold 41 to control the flow of the flushing fluid. When the solenoid valve 49 is open, the flushing fluid can flow from the quick-change manifold 41 through the quick-change silicone hose 42 to the peristaltic metering pump 43 and then be pumped to the outlet pipe. When the solenoid valve 49 is closed, the flow of the flushing fluid is cut off, achieving precise control of the flushing process. The quick-change silicone hose 42 is an easily installable and detachable hose used to connect the quick-change manifold 41, the peristaltic metering pump 43, and the outlet pipe. Its material is soft and corrosion-resistant, and it can withstand the squeezing of the peristaltic metering pump 43 without breaking. The quick-change design enables users to quickly replace the silicone hose to maintain the hygiene and performance of the flusher. The quick-change manifold 41 is a plate component integrating multiple fluid channels for distributing the flushing fluid from the inlet pipe to different paths (such as to the peristaltic metering pump 43 through the solenoid valve 49). It also provides a platform for installing the liquid level detection sensor 47 and the constant temperature module 48. The design of the quick-change manifold 41 allows these components to be easily installed and removed, facilitating maintenance and upgrading. The liquid level detection sensor 47 is used to monitor the liquid level of the flushing fluid in the quick-change manifold 41 or related containers in real time. When the liquid level is below the preset threshold, the sensor sends a signal to the control circuit board 45 to remind the user to replenish the flushing fluid in a timely manner. This helps to avoid interruptions during the flushing process due to insufficient flushing fluid. The constant temperature module 48 is responsible for controlling the temperature of the flushing fluid. It usually includes a heater and a temperature sensor. By reading the data of the temperature sensor, the constant temperature module 48 can intelligently adjust the power of the heater to keep the flushing fluid within the set temperature range. This helps to provide a comfortable flushing experience and reduce irritation caused by temperature changes. Finally, the stepless voltage regulation module 410 is docked with the peristaltic metering pump 43 to precisely adjust the output pressure of the pump. By changing the output signal of the module, the rotation speed and squeezing degree of the peristaltic metering pump 43 can be controlled, thereby achieving continuously adjustable flushing fluid flow. This design enables users to customize the flushing intensity according to personal needs, improving applicability. Moreover, each of the above modules is small in size and light in weight, making the device very convenient to use.

[0048] On the front of the body 1, there are an infinitely variable flow pressure regulating knob 14, a plugging and expanding open button 15, a plugging and expanding closed button 16, a flushing switch open button 17, a flushing switch closed button 18, and a power on / off button 19. The infinitely variable flow pressure regulating knob 14 is used to control the operation of the infinitely variable pressure regulating module 410. The plugging and expanding open button 15 and the plugging and expanding closed button 16 are used to control the expansion of the cleaning liquid outlet pipe. The flushing switch open button 17 and the flushing switch closed button 18 are used to control the switch of the peristaltic metering pump 43.

[0049] As described above, first of all, the infinitely variable flow pressure regulating knob 14 allows the user to continuously adjust the flow rate and pressure of the flushing liquid. When the user rotates the infinitely variable flow pressure regulating knob 14, it sends a signal to the control circuit board 45, which in turn controls the output of the infinitely variable pressure regulating module 410. The infinitely variable pressure regulating module 410 adjusts the rotation speed and extrusion degree of the peristaltic metering pump 43 according to the received signal, so as to achieve fine adjustment of the flow rate and pressure of the flushing liquid. The plugging and expanding open button 15 and the plugging and expanding closed button 16 are used to control the start and stop of the air pump a, that is, to control the expansion function of the outer layer pipe of the cleaning liquid outlet pipe. For example, the outer layer of the liquid outlet pipe is connected with a wrapping pipe, which has the performance of expansion. The side of the wrapping pipe is connected to the air pump a installed inside the body 1 through a connecting pipe. See Figure 8 , when the plugging and expanding open button 15 is pressed, the control circuit board 45 will activate the internal air pump a, causing the end wrapping pipe of the cleaning liquid outlet pipe to expand, so as to better fit the rectal wall, reduce the leakage of the flushing liquid and improve the flushing effect. On the contrary, when the plugging and expanding closed button 16 is pressed, this mechanism will release the pressure, causing the outer wrapping pipe of the cleaning liquid outlet pipe to return to the unexpanded state. This design helps the user to flexibly adjust the shape and fitting degree of the cleaning liquid outlet pipe according to actual needs. The flushing switch open button 17 and the flushing switch closed button 18 are used to control the start and stop of the peristaltic metering pump 43. Here, it should be noted that a flow sensor b should be set at the liquid inlet. See Figure 8 , to prevent liquid from entering after the pause or stop operation, and also to avoid injury. The connecting air inlet pipe between the wrapping pipe and the air pump a is installed with a pressure sensor c, which gives feedback when the pressure is too high to prevent injury. The power on / off button 19 is used to control the power switch of the entire flushing device. When the user presses the power on / off button 19, the flushing device will start and enter the standby state, waiting for the user's further operation. When the power on / off button 19 is pressed again, the flushing device will turn off the power and stop all functions. This design helps to save energy and extend the service life of the flushing device. The above buttons make the operation of this device simple and fast, suitable for different people to quickly get started.

[0050] The back cover of the body 1 is detachably installed for taking out the quick-change silicone tube 42 and the quick-change manifold 41.

[0051] S1: Device assembly and connection:

[0052] First, the user connects the washing liquid medicine bag or the flushing head / anal tube to the liquid inlet pipe at the upper end and the liquid outlet pipe at the lower end of the machine body 1 through the plastic conduit 2. The plastic conduit 2 cooperates with the locking assembly 3 at the upper and lower ends of the machine body 1. By meshing the tooth track on the outer wall of the ring plate 33 with the tooth track on the side end of the plastic conduit 2, a stable connection is achieved. At the same time, under the action of the notch docking spring 34, the limiting rod 35 is stuck in the groove on the inner wall of the ring plate 33 to prevent the ring plate 33 from rotating randomly, thereby ensuring the stability of the connection.

[0053] S2: Flushing liquid delivery and adjustment:

[0054] When the user presses the flushing switch on button 17, the control circuit board 45 receives the signal and starts the peristaltic metering pump 43. The peristaltic metering pump 43 starts to work, extracts the flushing liquid from the washing liquid medicine bag through the quick-change silicone tube 42 at the quick-change manifold 41, and transports it to the liquid outlet pipe inside the machine body 1. The user can adjust the output pressure of the stepless pressure regulating module 410 through the stepless flow rate and pressure regulating knob 14, thereby controlling the delivery speed and pressure of the peristaltic metering pump 43 to achieve precise adjustment of the flushing liquid.

[0055] S3: Constant temperature and liquid level detection:

[0056] The constant temperature module 48 continuously monitors the temperature of the flushing liquid and heats or keeps it warm according to the preset value to ensure that the flushing liquid remains within the appropriate constant temperature range. The liquid level detection sensor 47 is installed on the quick-change manifold 41 to detect the liquid level of the flushing liquid. When the liquid level is lower than the preset value, the sensor will send a signal to the control circuit board 45 to remind the user to replenish the flushing liquid in time.

[0057] S4: Control of the expansion of the cleaning liquid outlet pipe:

[0058] The user can control the expansion state of the cleaning liquid outlet pipe through the plugging expansion open button 15 and the plugging expansion close button 16. When it is necessary to increase the flushing pressure, the plugging expansion open button 15 can be opened to expand the liquid outlet pipe, thereby increasing the flushing effect. When the flushing is over, press the plugging expansion close button 16 to restore the liquid outlet pipe to its original state.

[0059] S5: Maintenance and cleaning:

[0060] The machine cover on the back of the machine body 1 is of a detachable design. The user can open the machine cover at any time, take out the quick-change silicone tube 42 and the quick-change manifold 41 for replacement to ensure the hygiene and performance of the device.

10. A method for using a constant temperature portable automatic rectal fixed-point irrigator according to any one of claims 1 to 9, characterized in that: The method of use comprises the following steps: S1: Device assembly and connection: The user first connects the detergent bag or the flushing head / anal tube to the liquid inlet pipe at the upper end and the liquid outlet pipe at the lower end of the machine body (1) through the plastic conduit (2). The plastic conduit (2) cooperates with the locking components (3) at the upper and lower ends of the machine body (1). The teeth on the outer wall of the ring plate (33) mesh with the teeth on the side end of the plastic conduit (2) to achieve a stable connection. At the same time, the limiting rod (35) is stuck in the groove on the inner wall of the ring plate (33) under the action of the notch docking spring (34), preventing the ring plate (33) from rotating at will, thereby ensuring the stability of the connection. S2: Flushing fluid delivery and regulation: When the user presses the flushing switch on button (17), the control circuit board (45) receives the signal and starts the peristaltic metering pump (43). The peristaltic metering pump (43) starts to work and extracts the flushing liquid in the detergent bag from the quick-change manifold (41) through the quick-change silicone tube (42) and delivers it to the liquid outlet pipe inside the machine body (1). The user can adjust the output pressure of the stepless pressure regulating module (410) through the stepless flow pressure regulating knob (14), thereby controlling the delivery speed and pressure of the peristaltic metering pump (43) and realizing accurate regulation of the flushing liquid. S3: Constant temperature and liquid level detection: The constant temperature module (48) monitors the temperature of the flushing liquid in real time and heats or keeps it warm according to a preset value to ensure that the flushing liquid is kept within a suitable constant temperature range. The liquid level detection sensor (47) is installed on the quick-change manifold (41) to detect the liquid level of the flushing liquid. When the liquid level is lower than the preset value, the sensor sends a signal to the control circuit board (45) to remind the user to replenish the flushing liquid in time. S4: Cleaning the liquid outlet pipe expansion control: The user can control the expansion state of the cleaning liquid outlet pipe by means of the blocking expansion on button (15) and the blocking expansion off button (16); when it is necessary to increase the flushing pressure, the blocking expansion on button (15) can be opened to expand the liquid outlet pipe, thereby increasing the flushing effect; when the flushing is completed, the blocking expansion off button (16) can be pressed to restore the liquid outlet pipe to its original state. S5: Maintenance and cleaning: The cover on the back of the machine body (1) is of detachable design, and the user can open the cover at any time to take out the quick-change silicone tube (42) and the quick-change manifold (41) for replacement, thereby ensuring the hygiene and performance of the device.
