Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to an automatic tube raising and lowering mechanism for a peristaltic pump. Background Art

[0002] As an advanced spray technology solution, pressurized atomization equipment mainly pressurizes water or other liquids to a certain pressure range through a peristaltic pump or a high-pressure pump, and then transports them to a special nozzle through a high-pressure pipeline. Inside the nozzle, the high-pressure liquid is mixed with compressed air, and after high-speed impact or shearing, small and uniform water mist particles are formed. These water mist particles are small in diameter and can quickly spread throughout the space. They have the characteristics of high efficiency, energy saving, environmental protection, safety and reliability, and have been widely used in industry, agriculture, public environment and medical fields.

[0003] The current pressurized atomization equipment in the medical field mainly relies on peristaltic pumps as the driving force for pressurization. When installing the tube, it is necessary to manually insert the tube into the peristaltic pump. Since the peristaltic pump squeezes the tube to obtain high pressure for the liquid in the tube, the distance between the rotor on the peristaltic pump and the outer installation space is small, which makes it more troublesome to install the tube.

[0004] Therefore, in order to ensure that there is more time for critical treatment operations during the medical process, the present application proposes a peristaltic pump automatic tube loading and unloading mechanism that can greatly reduce the difficulty of tube installation and operation time. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings existing in the prior art, and a peristaltic pump automatic upper and lower tube mechanism is proposed, which can fully automate the upper and lower tube operations, and can truly avoid the difficulty of manual upper and lower tube operations. At the same time, for the medical field, the upper and lower tube operations can be completed quickly, so as to enter the pressurized atomization treatment process faster, reduce the time occupied by non-critical treatment operations, and there is no need to worry about contact with pollution sources during the operation and affecting the treatment efficiency.

[0006] In order to achieve the above object, the present invention provides the following technical solutions: A peristaltic pump automatic tube upper and lower mechanism comprises a machine base, a groove arranged on the surface of the machine base and a pump head rotatably connected to the groove; A clamp for fixing both ends of the pipe and being retractable in the groove is also provided on one side of the groove. The pump head includes a turntable and a plurality of eccentric wheels rotatably connected to the turntable. The axial side wall of the eccentric wheel is provided with an annular groove that can adapt to the pipe; wherein: The annular groove is located below the top of the groove. When the clamp is retracted into the groove, the tube is fixed, so that the tube is clamped into or out of the annular groove when the turntable rotates.

[0007] Through the above structure, a method for fully automating the upper and lower tube operations is constructed, which can truly avoid the difficulty of manual upper and lower tube operations. At the same time, for the medical field, the upper and lower tube operations can be completed quickly, so as to enter the pressurized atomization treatment process faster, reduce the time occupied by non-critical treatment operations, and there is no need to worry about contact with pollution sources during the operation and affecting the treatment efficiency.

[0008] Preferably, the eccentric wheels are evenly distributed between each rotor.

[0009] Through the above structure, the probability of the eccentric wheel aligning with the pipe can be increased, thereby improving the efficiency of the upper and lower pipes and shortening the total operation time of the upper and lower pipes.

[0010] Preferably, a claw plate is fixedly connected to the turntable, and the claw plate is located on the same side of the eccentric wheel on the turntable. The edge of the claw plate extends outward from the wheel frame along the radial direction of the turntable, and both ends of each eccentric wheel are rotatably connected to the wheel frame and the turntable respectively.

[0013] Through the above structure, while improving the production efficiency, it can ensure that the process of automatic tube loading and unloading is not hindered and affects the process of the entire tube loading and unloading and treatment operation.

[0014] Preferably, the clip includes a main body, an elastic clamp located on the side wall of the main body, and a pushing mechanism for driving the main body to extend and retract in the groove, the bottom of the elastic clamp is connected to the main body, and the upper part of the elastic clamp is naturally expanded outward to form an accommodating portion that can adapt to the shape of a tube between the main body.

[0015] Through the above structure, an interference fit can be formed when the pipe is clamped, thereby overcoming the traction force of the eccentric wheel on the pipe when the pipe is put on, avoiding the pipe slipping phenomenon that causes the automatic pipe putting process to fail to complete for a long time, thereby ensuring that the automatic pipe putting on and putting off function provided by this technical solution is efficient.

[0016] Preferably, the main body and / or the top edge of the elastic clamping plate is also provided with an anti-slip portion protruding into the accommodating portion.

[0017] The above structure can prevent the tube from slipping and falling off the accommodating portion during the tightening process of the accommodating portion, thereby ensuring that the automatic tube-loading function is effective and that the automatic tube-dropping function is not disturbed.

[0018] Preferably, the machine base is further provided with a first card slot located at one side of the pipe input end, the first card slot can be adapted to the clamping head on the pipe, and a first connecting groove adapted to the pipe is provided between the card slot and the groove.

[0019] Through the above structure, the tube will not move axially due to traction during the pressurized atomization process and the automatic tube-loading process, thereby ensuring that the automatic tube-loading function is effective without affecting the pressurized atomization process and ensuring that the non-therapeutic operation process before treatment is efficient.

[0020] Preferably, the base is further provided with a second card slot located at one side of the output end of the pipe, the second card slot can be adapted to the clamping head on the pipe, and a second connecting groove adapted to the pipe is provided between the second card slot and the groove.

[0021] Through the above structure, the automatic tube lowering function is ensured to be effective and efficient, making non-treatment operations after treatment faster and more rapid.

[0022] Preferably, the communicating groove extends to the outer side of the base, and the base is further provided with a door for covering the surface of the base.

[0023] Through the above structure, under the condition of ensuring that the pressurized atomization process is not affected, the transmission of pollutants inside and outside the base is isolated, the noise generated during the pressurized atomization process can be reduced, and the pressurized atomization process can be ensured to be carried out safely and stably.

[0024] Preferably, a control module is further included, and the output end of the control module controls the input end connected to the pump head and the clamp respectively.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1: See also Figure 1-4 , the present invention provides the following technical solutions: a peristaltic pump automatic tube up and down mechanism, comprising a base 1, a groove 11 provided on the surface of the base 1, and a pump head 2 rotatably connected to the groove 11; A clamp 3 for fixing both ends of the tube 6 and being retractable in the groove 11 is also provided on one side of the groove 11. The pump head 2 includes a turntable 21 and a plurality of eccentric wheels 22 rotatably connected to the turntable 21. The axial side wall of the eccentric wheel 22 is provided with an annular groove 221 that can adapt to the tube 6; wherein: The annular groove 221 is located below the top of the groove 11 , and when the clamp 3 is retracted into the groove 11 , the tube 6 is fixed, so that the tube 6 is stuck in or out of the annular groove 221 when the turntable 21 rotates.

[0035] As an optional implementation scheme of the present invention, when installing the tube, the two ends of the tube 6 are placed on the clamp 3 respectively. At this time, the clamp 3 can be controlled to retract so that the two ends of the tube 6 are fixed. At the same time, the tube 6 is located at the position of the clamp 3 and is already inside the groove 11. Since the groove 11 and the bottom of the clamp 3 are connected and the position is very close, the remaining part of the tube 6 that has not entered the groove 11 can be aligned with the edge of the groove 11 that is in contact with pressure, or contact the pump head 2, or contact the rotor 23 on the pump head 2, or contact the eccentric wheel 22, or contact the edge of the base 1 close to the groove 11, and then the pump head 2 of the peristaltic pump itself is controlled to rotate so that the eccentric wheel 22 follows the rotation of the turntable 21. Since the eccentric wheel 2 There must be a gap between the eccentric wheel 22 and the rotor 23. When the gap between the eccentric wheel 22 and the rotor 23 is just aligned with the part of the pipe 6 that has not entered the groove 11, the pressure of the pipe 6 is released and the pipe 6 enters the groove 11. When the rotating disk 22 is continuously rotated to bring the next eccentric wheel 22 to the right position, the annular groove 221 on the eccentric wheel 22 can contact and accommodate the pipe 6. The pipe 6 is always in a fixed state and cannot slip axially. Therefore, the remaining part of the pipe 6 that has not entered the groove 11 will be pushed into the groove 11 along the side wall of the groove 11 by the continuously rotating eccentric wheel 22. When the eccentric wheel 22 moves one circle, the pipe 6 will completely enter the groove 11, thereby realizing a fully automated pipe loading operation. When lowering the tube, first control the clamp 3 to extend so that the tube 6 located at the clamp 3 is exposed from the surface of the base 1 and is completely loosened by the clamp 3. At this time, the released part of the tube 6 exerts an outward force (traction force composed of shear force, elastic force or tension, etc.) on the unreleased part still in the groove 11. Then the pump head 2 of the peristaltic pump is controlled to reverse. When the distance between the rotor 23 and the eccentric wheel 22 moves to the junction of the groove 11 and the clamp 3, the tube 6 can be gradually loosened.

[0036] During the entire process of placing and removing the tube, there is no need to manually place the tube 6 into the relatively narrow space between the groove 11 and the side of the pump head 2. This can effectively isolate the medical staff's hands from touching the tube 6, the pump head 2 or other locations on the equipment to prevent contamination that affects the treatment process and efficiency. Secondly, the entire process can be fully automated, which is faster and directly avoids the difficulty of manual placing and removing the tube. This has a significant effect in many fields, especially the medical field.

[0037] In the present technical solution, the pump head 2 refers to the pump head 2 of the peristaltic pump; the clamp 3 refers to a component that releases the tube 6 after extending out of the groove 11 and fixes the tube 6 after retracting into the groove 11. It can be an elastic clamp, such as the structure mentioned later, or it can be an automated structure. The present technical solution does not make specific limitations on it. It should be understood that any solution that can achieve loosening or clamping of the tube 6 in the above-mentioned manner can be regarded as within the protection scope of the clamp 3.

[0038] As for the eccentric wheel 22, theoretically, only one eccentric wheel 22 can realize the function of automatically raising and lowering the tubes. However, since the initial position of the eccentric wheel 22 is not necessarily fixed when the rotating disk stops or starts, technicians in this field can set more eccentric wheels 22, or set the start and stop procedures of the rotating disk to obtain a more efficient raising and lowering tube function.

[0039] Through the above structure, a method for fully automating the upper and lower tube operations is constructed, which can truly avoid the difficulty of manual upper and lower tube operations. At the same time, for the medical field, the upper and lower tube operations can be completed quickly, so as to enter the pressurized atomization treatment process faster, reduce the time occupied by non-critical treatment operations, and there is no need to worry about contact with pollution sources during the operation and affecting the treatment efficiency.

[0040] like Figure 1-4 As shown, the eccentric wheels 22 are evenly distributed between each rotor 23 .

[0041] As an optional implementation scheme of the present invention, as mentioned above, although only one eccentric wheel 22 is provided to realize the function of automatically raising and lowering the tube, the initial position of the eccentric wheel 22 is not necessarily fixed when the rotating disk stops or starts. Therefore, multiple eccentric wheels 22 are provided and the eccentric wheels 22 are evenly distributed on the rotating disk 21. The probability of the eccentric wheel 22 aligning with the tube 6 can be increased, thereby improving the efficiency of raising and lowering the tube and shortening the total operation time of the raising and lowering the tube.

[0042] Through the above structure, the probability of the eccentric wheel 22 being aligned with the pipe 6 can be increased, thereby improving the efficiency of the upper and lower pipes and shortening the total operation time of the upper and lower pipes.

[0043] like Figure 4 As shown, a claw plate 25 is fixedly connected to the turntable 21, and the claw plate 25 is located on the same side of the turntable 21 as the eccentric wheel 22. The edge of the claw plate 25 extends outward from the wheel frame 251 along the radial direction of the turntable 21, and the two ends of each eccentric wheel 22 are rotatably connected to the wheel frame 251 and the turntable 21 respectively.

[0044] As an optional implementation scheme of the present invention, since the application scenarios of peristaltic pumps or pressurized atomization equipment are very broad, it is very likely that a higher liquid pressure will be required in certain specific situations. Therefore, the rotation speed of the peristaltic pump needs to be relatively high. The method of assembling the two ends of the eccentric wheel 22 by using a wheel frame 251 makes the force on the eccentric wheel 22 more balanced, and can effectively prevent the eccentric wheel 22 from vibrating or even falling off due to the large centrifugal force during the operation of the peristaltic pump, thereby preventing the automatic upper and lower tube functions from failing.

[0045] The above structure makes the force on the eccentric wheel 22 more balanced, which can effectively prevent the eccentric wheel 22 from vibrating or even falling off due to the large centrifugal force during the operation of the peristaltic pump, thereby preventing the automatic upper and lower tube function from failing.

[0046] like Figure 3 As shown, the groove 11 is a circular groove that can adapt to the rotor 23 on the pump head 2 to squeeze the tube 6 when the pump head 2 rotates, and part of the edge of the groove 11 extends to the bottom of the position where the clamp 3 is located; the diameter of the circle enclosed by each rotor 23 is not less than the diameter of the circle enclosed by each annular groove 221.

[0047] As an optional embodiment of the present invention, it should be understood that the groove 11 can accommodate the installation of the pump head 2 and the clamp 3 at the same time, thereby reducing the process complexity during machining and manufacturing and reducing production costs. Secondly, it ensures that after the tube 6 is clamped and fixed by the clamp 3, the tube 6 can naturally have pressure contact with the components within the range of the pump head 2, and will not encounter additional obstacles in the process of entering the groove 11 to affect the process of automatic tube loading, and will not encounter additional resistance when lowering the tube to affect the process of lowering the tube.

[0048] Through the above structure, while improving the production efficiency, it can ensure that the process of automatic tube loading and unloading is not hindered and affects the process of the entire tube loading and unloading and treatment operation.

[0049] like Figure 4 As shown, the clamp 3 includes a main body 31, an elastic clamp 32 located on the side wall of the main body 31, and a pushing mechanism 33 for driving the main body 31 to extend and retract in the groove 11. The bottom of the elastic clamp 32 is connected to the main body 31, and the upper part of the elastic clamp 32 is naturally expanded outward and forms a receiving portion 34 that can adapt to the shape of the tube 6 between the main body 31.

[0050] As an optional implementation scheme of the present invention, after the tube 6 is placed in the accommodating portion 34, during the process of the clamp 3 retracting into the groove 11, the elastic clamp 32 is limited by the side wall of the groove 11 and gathers toward the main body 31, so that the space of the accommodating portion 34 is reduced, thereby forming a pressure contact with the tube 6 located in the accommodating portion 34. The tube 6 is generally a plastic part, so it has an interference fit effect, making it difficult for the tube 6 to slip axially after being clamped by the clamp 3. During the automatic tube loading and unloading process, slipping due to the traction force of the eccentric wheel 22 on the tube 6 can be avoided, resulting in a long time for the automatic tube loading and unloading process to be completed, thereby ensuring that the automatic tube loading and unloading function provided by the present technical solution is efficient.

[0051] In the present technical solution, it is worth noting that the interference fit formed by the accommodating portion 34 on the tube 6 due to the retracted groove 11 of the clamp 3 is not too strong. Since the method of clamping the tube 6 provided by the present technical solution is not completely uniform during the process of pressurizing the tube 6, when the force is too large, the tube 6 will be deformed and affect the flow rate. Therefore, the clamping force of the clamp 3 on the tube 6 only needs to be sufficient to overcome the traction force of the eccentric wheel 22 on the tube 6 when the tube is installed.

[0052] Through the above structure, an interference fit can be formed when the pipe 6 is clamped, thereby overcoming the traction force of the eccentric wheel 22 on the pipe 6 when the pipe is placed, avoiding the slipping of the pipe 6 and causing the automatic pipe placing process to fail to be completed for a long time, thereby ensuring that the automatic pipe placing and lowering function provided by the technical solution is efficient.

[0053] like Figure 4 As shown, the top edge of the main body 31 and / or the elastic clamping plate 32 is further provided with an anti-slip portion 35 protruding into the accommodating portion 34 .

[0054] As an optional implementation scheme of the present invention, in the process of the clamp 3 retracting into the groove 11, the tube 6 will be gradually clamped, but there is a probability that the tube 6 will slip and be squeezed out of the accommodating portion 34, so the anti-slip portion 35 is provided on the top edge of the main body 31 or / and the elastic clamp 32, which can well block the tube 6, thereby ensuring that the tube 6 will not detach from the clamp 3 and cause the entire automatic tube loading function to fail. It is worth noting that the anti-slip portion 35 should refer to a component that can prevent the tube 6 from being squeezed out during the tightening of the accommodating portion 34. It can be in the shape of a plate, an inverted U, or other shapes. All specific structures that can achieve this function should belong to the specific implementation means of the anti-slip portion 35.

[0055] In the present technical solution, it is preferred to set a plate-shaped anti-slip portion 35 at least on the top edge of the main body 31, mainly because the main body 31 does not deform during the tightening of the accommodating portion 34, and thus the anti-slip portion 35 does not move. Only after the elastic clamp 32 is triggered to move toward the main body 31 will the top of the tube 6 be aligned with the anti-slip portion 35. In this way, the tube 6 is not blocked from being placed in the accommodating portion 34 when the clamp 3 is in a natural state, nor is the tube 6 blocked and difficult to escape from the accommodating portion 34 when the tube is automatically lowered. The plate-shaped accommodating portion 34 is not only simple in structure, but also sufficiently stable in effect, and does not require further inverted U-shaped design to easily prevent the tube 6 from escaping from the accommodating portion 34.

[0056] The above structure can prevent the tube 6 from slipping and falling off the accommodating portion 34 during the tightening process of the accommodating portion 34, thereby ensuring that the automatic tube-loading function is effective and that the automatic tube-dropping function is not disturbed.

[0057] like Figure 3 and Figure 5 As shown, the base 1 is also provided with a first card slot 12 located at one side of the input end of the pipe 6, the first card slot 12 can be adapted to the clamping head 62 on the pipe 6, and a first connecting groove 13 adapted to the pipe 6 is provided between the first card slot 12 and the groove 11.

[0058] As an optional implementation scheme of the present invention, as mentioned above, the clamping force of the clamp 3 on the tube 6 is not too large to interfere with the shape of the tube 6. Therefore, the traction force on the tube 6 caused by the rotation of the pump head 2 during the pressurized atomization process, and the traction force of the eccentric wheel 22 on the tube 6 during the automatic tube upper and lowering process, may cause the tube 6 to slip in the axial direction, which will not only reduce the efficiency of the automatic tube upper and lowering function or even directly fail the function, but also affect the pressurized atomization process. Therefore, it is necessary to fix the axial direction of the tube 6 to ensure the effectiveness of the entire pressurized atomization equipment and the automatic tube upper and lowering function.

[0059] Among them, considering that hospitals often pay more attention to the efficiency of non-therapeutic operations before treatment, the first card slot 12 is more clearly inclined to point to the liquid input end of the tube 6, that is, the end of the tube 6 that is subjected to traction and has an axial movement direction when the tube is automatically mounted, and this end is also in line with the rotation direction of the pump head 2 during pressurized atomization. Then, the first card slot 12 is set at this end of the tube 6 to lock the tube 6, thereby resisting the axial pulling force generated during pressurized atomization and automatic tube mounting, and preventing the tube 6 from being pulled, which can well ensure that the non-therapeutic operation process before treatment is completely efficient; In addition, the setting of the first connecting groove 13 can enable the input end of the entire tube 6 to be embedded below the surface of the base 1 as a whole after installation, so as to avoid the tube 6 in the section from the groove 11 to the first slot 12 being squeezed and deformed by the surface of the base 1 when subjected to traction, thereby affecting the pressurized atomization process. Therefore, the design of the first connecting groove 13 is necessary.

[0060] Through the above structure, the tube 6 will not produce axial movement due to traction during the pressurized atomization process and the automatic tube-loading process, ensuring the effectiveness of the automatic tube-loading function without affecting the pressurized atomization process, and ensuring the efficiency of the non-therapeutic operation process before treatment.

[0061] like Figure 3 and Figure 5 As shown, the base 1 is also provided with a second slot 14 located at one side of the output end of the tube 6 , the second slot 14 can be adapted to the clamp 62 on the tube 6 , and a second connecting slot 15 adapted to the tube 6 is provided between the second slot 14 and the groove 11 .

[0062] As an optional implementation scheme of the present invention, as mentioned above, the input end of the tube 6 is designed with the first slot 12 so that the tube 6 is not moved by traction during the automatic tube loading process. Then, the second slot 14 is designed at the output end of the tube 6 so that the tube 6 is not moved by traction during the automatic tube lowering process. This technical solution is mainly intended to ensure that the automatic tube lowering function is effective and efficient.

[0063] The present technical solution can be used in combination with the design of the first card slot 12 mentioned above. Of course, the embodiment can choose to implement either the first card slot 12 or the second card slot 14, or both can be implemented at the same time, and both should fall within the protection scope of the present embodiment; when the two technical solutions are implemented at the same time, the automatic upper and lower tube functions are effective and efficient at the same time, thereby making the entire pre-treatment operation, treatment operation during treatment, and pressurized atomization process effective and efficient.

[0064] Through the above structure, the automatic tube lowering function is ensured to be effective and efficient, making non-treatment operations after treatment faster and more rapid.

[0065] like Figure 1-3As shown, the communicating groove extends to the side outer portion of the base 1 , and the base 1 is further provided with a door 4 for covering the surface of the base 1 .

[0066] As an optional implementation scheme of the present invention, the entire tube 6 is placed in two connecting grooves so that the entire tube 6 is located within the surface of the machine base 1, which can ensure that the tube 6 is not affected by lateral pressure during the pressurized atomization process, and is not affected by the pressure of the machine door 4; the set machine door 4 completely isolates the tube 6 and the pump head 2 in the machine base 1 from the outside, which can appropriately reduce the noise generated when the peristaltic pump is in operation, and especially can isolate the transmission of pollution sources inside and outside the machine base 1, especially the pollutants on the machine base 1 are transmitted to the air in the operating room, and can also to a certain extent avoid the flying of parts and affect medical staff when the peristaltic pump is damaged due to abnormal operation, and prevent foreign objects from being drawn into the pump head during the pressurized atomization process, causing damage or accidental injury, thereby ensuring that the pressurized atomization process can be carried out safely and stably.

[0067] Through the above structure, under the condition of ensuring that the pressurized atomization process is not affected, the transmission of pollutants inside and outside the base 1 is isolated, the noise generated during the pressurized atomization process can be reduced, and the pressurized atomization process can be ensured to be carried out safely and stably.

[0068] In the present technical solution, those skilled in the art may further design a sound insulation pad or a sealing pad on the machine door 4 or the machine base 1 to enhance the noise isolation performance or reduce the pollution transmission capability.

[0069] like Figure 5 As shown, a control module 5 is also included, and the output end of the control module 5 controls the input end connected to the pump head 2 and the clamp 3 respectively.

[0070] As an optional implementation scheme of the present invention, the control module 5 refers to a functional element that can control the operation of the pump head 2 and the clamp 3, and can be a touch screen, a button, a knob, a control keyboard, etc., and the present technical solution does not make any specific limitations on it; technical personnel in this field can also further design a control method on this basis, such as running the automatic tube lowering program immediately after the pressurized atomization process is completed, and can also add a sensor that automatically senses the tube 6 when it is placed in the first slot 12, the second slot 14 and / or the clamp 3, so as to achieve a more automated automatic tube lowering and lowering action.

[0071] Through the above structure, medical staff can operate the automatic tube upper and lower mechanism more conveniently.

[0072] Embodiment 2: See also Figure 5 The present invention also provides the following technical solution: a tube for a peristaltic pump, comprising a tube body 61, on which two clamps 62 are provided.

[0073] As an optional embodiment of the present invention, as mentioned above, due to the design of the first card slot 12 and / or the second card slot 14, a tube 6 with a clamp 62 must be specifically equipped to be applicable to the automatic tube loading and unloading mechanism, so the present application also proposes a tube 6 suitable for use with the automatic tube loading and unloading mechanism. It should be understood by those skilled in the art that the spacing value of the two clamps 62 on the tube 6 should be applicable to the automatic tube loading and unloading mechanism of the corresponding specifications and models, and should be customized to the standard. Of course, those skilled in the art can also make further improvements on the tube 6, but ultimately the purpose of achieving the spacing of the two clamps 62 as a fixed value should be achieved, so as to ensure that the functions of true pressurized atomization and automatic tube loading and unloading are effective.

[0074] In actual use, a separate package can be used as a carrier of the tube 6 product, and the tube 6 is used as a disposable consumable.

[0075] Through the above structure, a tube 6 suitable for use in the automatic tube raising and lowering mechanism is provided, which ensures that the functions of pressurized atomization and automatic tube raising and lowering are effective.

[0076] Embodiment 3: See also Figure 4 and Figure 6 The present invention also provides the following technical solution: a pressurizing device, including the above-mentioned automatic upper and lower tube mechanism and the above-mentioned tube 6, and the turntable 21 is also eccentrically provided with a plurality of rotors 23 for squeezing the tube 6 and a driving mechanism 24 for driving the turntable 21 to rotate.

[0077] Through the above structure, a pressurized device is constructed that can fully automate the upper and lower tube operations, which can truly avoid the difficulty of manual upper and lower tube operations. At the same time, for the medical field, the upper and lower tube operations can be completed quickly, so as to enter the pressurized atomization treatment process faster, reduce the time occupied by non-critical treatment operations, and there is no need to worry about contact with pollution sources during the operation and affecting the treatment efficiency.

[0078] The working principle and use process of the present invention are as follows: when putting on the tube, the two ends of the tube 6 are placed on the clamp 3 respectively, and at this time the clamp 3 can be controlled to retract so that the two ends of the tube 6 are fixed, and at the same time the tube 6 is already inside the groove 11 at the position of the clamp 3, and because the groove 11 and the bottom of the clamp 3 are connected and the position is very close, the remaining part of the tube 6 that has not entered the groove 11 can be aligned with the edge of the groove 11 that contacts with pressure in the groove 11, or contacts the pump head 2, or contacts the rotor 23 on the pump head 2, or contacts the eccentric wheel 22, or contacts the edge position of the base 1 close to the groove 11, and then the pump head 2 of the peristaltic pump itself is controlled to rotate, so that the eccentric wheel 22 follows the rotation of the turntable 21, and because the eccentric wheel 22 There must be a gap between the eccentric wheel 22 and the rotor 23. When the gap between the eccentric wheel 22 and the rotor 23 is just aligned with the part of the pipe 6 that has not entered the groove 11, the pressure of the pipe 6 is released and the pipe 6 enters the groove 11. When the rotating disk 22 is continuously rotated to bring the next eccentric wheel 22 to the right position, the annular groove 221 on the eccentric wheel 22 can contact and accommodate the pipe 6. The pipe 6 is always in a fixed state and cannot slip axially. Therefore, the remaining part of the pipe 6 that has not entered the groove 11 will be pushed into the groove 11 along the side wall of the groove 11 by the continuously rotating eccentric wheel 22. When the eccentric wheel 22 moves one circle, the pipe 6 will completely enter the groove 11, thereby realizing a fully automated pipe loading operation. When lowering the tube, first control the clamp 3 to extend so that the tube 6 located at the clamp 3 is exposed from the surface of the base 1 and is completely loosened by the clamp 3. At this time, the released part of the tube 6 exerts an outward force (traction force composed of shear force, elastic force or tension, etc.) on the unreleased part still in the groove 11. Then the pump head 2 of the peristaltic pump is controlled to reverse. When the distance between the rotor 23 and the eccentric wheel 22 moves to the junction of the groove 11 and the clamp 3, the tube 6 can be gradually loosened.

[0079] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
