Description

Technical Field

[0001] This application belongs to the technical field of laboratory instrument and equipment cleaning devices, and particularly relates to a heating cleaning device. Background Technology

[0002] In laboratory preparation and small-batch production, the three-necked flask is the most commonly used standard reaction vessel. However, due to the long and narrow neck of the three-necked flask and the difficulty in accessing its internal structure, after the adhesive-related reactions are completed inside the flask, the adhesive residue may gradually solidify or form a semi-solid gel state. This residual adhesive adheres very firmly to the inner wall, bottom, and the inside of the three narrow and complex necks of the flask, creating a difficult-to-remove residue problem. Currently, the main methods for cleaning such residues inside three-necked flasks include: organic solvent immersion, which not only consumes a large amount of solvent and is costly, but also because most organic solvents are highly volatile and toxic, posing a threat to the health of operators; ultrasonic cleaning, in which the energy of ultrasound is attenuated after passing through the glass wall, and its cleaning effect is limited for large areas of completely cured thick layers of residue, often failing to completely remove it; and mechanical scraping, where operators attempt to manually scrape with tools such as metal scrapers and wires. This method is inefficient and easily leaves scratches on the inner wall of the glass, damaging the container. At the same time, it is very difficult to operate in the narrow neck, and there is a safety risk of tools getting stuck or causing the glass to break. Utility Model Content

[0008] In addition, there is an electric heating element 500, which is disposed inside the directional flexible connecting pipe 300, and its heating part is thermally connected to the heat-conducting pile 310.

[0009] In this application, the drive handle 100 includes a switch panel 110, a temperature control panel 120, a display panel 130, and a control circuit 140.

[0010] In this application, the control circuit 140 includes at least a microcontroller unit 141, which is disposed within the drive handle 100;

[0011] Temperature sensor 142, whose signal output terminal is connected to the analog-to-digital conversion interface of the microcontroller unit 141, is used to detect the temperature of the heat-conducting pile 310 or the electric heating element 500.

[0012] The power drive module 143 has its control input terminal connected to the pulse width modulation output terminal of the microcontroller unit 141, and its output terminal electrically connected to the heating element 500.

[0013] The output terminal of the switch panel 110 is connected to the input port of the microcontroller unit 141; the output terminal of the temperature control panel 120 is connected to the input port of the microcontroller unit 141; and the receiving terminal of the display panel 130 is connected to the output port of the microcontroller unit 141.

[0014] In this application, the heating element 500 includes a heating wire 510; the heating wire 510 is wound around the wall of the heat-conducting pile 310.

[0015] In this application, the directional flexible connecting tube 300 further includes: a metal serpentine tube 330, and an insulating and heat-conducting layer 340 wrapped around the outside of the metal serpentine tube 330; wherein, the heating element 500 is disposed between the metal serpentine tube 330 and the insulating and heat-conducting layer 340.

[0016] In this application, the heat-conducting pile 310 is provided with a metal protective shell 311 on its exterior; the metal protective shell 311 covers the sidewalls and base of the heat-conducting pile 310 except for the ends.

The heat is then efficiently conducted to the cleaning head 410 via a heat-conducting connecting seat 421 in a magnetic connecting assembly 420. This process precisely heats and softens stubborn adhesive residue on the inner wall of a three-necked flask, significantly reducing its adhesion and making subsequent mechanical removal easy and efficient. This overcomes the drawbacks of relying solely on chemical solvents or mechanical scraping, while avoiding hard damage to the glass flask wall. Furthermore, the directional flexible connecting tube 300's ability to bend and shape arbitrarily allows the operator to flexibly and precisely guide the cleaning actuator 400 into the spherical body, bottom, and narrow side necks of the three-necked flask, achieving comprehensive coverage and efficient cleaning of complex cavities that traditional rigid tools cannot accomplish. In addition, based on the magnetic connection method consisting of magnetic component 320 and magnetic sheet 422, the cleaning execution component 400 can be quickly connected and disconnected from the directional flexible connecting tube 300. With the cleaning head 410 being a replaceable design, users can change to different types of cleaning heads 410 at any time, such as scraper brush head or high-temperature resistant steel wire brush head, depending on the nature of the residual adhesive, such as hard adhesive that needs to be scraped off forcefully or soft adhesive that needs to be gently brushed. This achieves multi-purpose functionality and greatly improves the convenience of operation and adaptability to working conditions. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] Example 1:

[0031] As attached Figure 1 As shown, to solve the above-mentioned technical problems, this application provides a heated cleaning device, which includes: a drive handle 100 and a connecting rod 200; one end of the drive handle 100 is connected to one end of the connecting rod 200. In this application, the drive handle 100 includes a switch panel 110, a temperature control panel 120, a display panel 130, and a control circuit 140.

[0032] It should be noted that in this embodiment, the switch panel 110 is used to control the switch of the heating function, and the temperature control panel 120 is used to control the heating temperature of the heating function. The cleaning device in this embodiment can not only heat, but also flexibly adjust the heating temperature according to the stubbornness of the residue adhering to the inner wall of the three-necked flask to be cleaned, thereby improving the flexibility and efficiency of heating.

[0033] Preferably, the display panel 130 can be used to display whether the LED light is in working condition, the current theoretical heating temperature, and the current actual heating temperature, etc., but is not limited to these.

[0034] In this embodiment, the control circuit 140 includes at least: a microcontroller unit 141 disposed within the drive handle 100; a temperature sensor 142 whose signal output terminal is connected to the analog-to-digital converter interface of the microcontroller unit 141 for detecting the temperature of the heat-conducting pile 310 or the heating element 500; and a power drive module 143 whose control input terminal is connected to the pulse width modulation output terminal of the microcontroller unit 141, and whose output terminal is electrically connected to the heating element 500.

[0035] It should be noted that the microcontroller unit mentioned above can be a single microcontroller chip, such as STM32, Arduino, or 51 microcontroller; the temperature sensor can be a thermistor, thermocouple, or digital temperature sensor DS18B20, etc.; in addition, modules such as operational amplifiers to form amplification or filtering circuits can be added for signal conditioning circuits, and are not limited to these; the power drive module can use power switching transistors, such as MOSFETs or IGBTs, and corresponding driver chips to execute the weak electrical signals issued by the MCU to control the strong electrical current to the heating element, and is not limited to these. The above temperature adjustment and measurement circuit components can be implemented through conventional matching and parameter tuning.

[0036] The output terminal of the switch panel 110 is connected to the input port of the microcontroller unit 141; the output terminal of the temperature control panel 120 is connected to the input port of the microcontroller unit 141; and the receiving terminal of the display panel 130 is connected to the output port of the microcontroller unit 141.

[0037] As attached Figure 2 The diagram shows the system framework and signal transmission direction of a preferred control circuit in this embodiment. It should be noted that the temperature sensor 142 is physically close to the heat-conducting pile 310 or in good thermal contact with the heating element 500, and its signal line is connected to the analog / digital input pin of the microcontroller chip (MCU). The temperature control panel 120, such as a potentiometer or encoder, is connected to another analog / digital input pin of the MCU. The display panel 130, such as an OLED screen or LED indicator, is connected to the MCU's I / O port or communication interface. One control pin of the MCU, such as a PWM output pin, is connected to the input of the power drive module 143, and the output of the power drive module 143 directly drives the heating element 500. In summary, the temperature control and heating function of the above-mentioned control circuit can be realized, with a simple structure and low production cost.

[0038] In this embodiment of the application, the device further includes:

[0039] A directional flexible connecting tube 300 is provided, one end of which is connected to the other end of the connecting main rod 200.

[0040] It should be noted that in this embodiment, the other end of the connecting main rod 200 may have an external thread, while a connecting sleeve with an internal thread is fixed to the outside of the metal snake tube at one end of the directional flexible connecting tube 300. The two can be securely connected by screwing on the connecting sleeve. This connection is strong and reliable, capable of transmitting large torque, and is not easily loosened during vigorous cleaning; it has good sealing properties, preventing cleaning agents from seeping into the interior; and it has a simple structure and low cost.

[0041] In other embodiments, the directional flexible connecting tube 300 and the connecting main rod 200 can also be a snap-fit ​​connection structure, an integrated design, etc., and can be connected according to actual needs, and are not limited thereto.

[0042] A cleaning actuator 400 is detachably mounted on the other end of the directional flexible connecting tube 300 via a magnetic connection.

[0043] It should be noted that the cleaning actuator 400 is a structural component that realizes the heating and cleaning functions. It is detachably installed at the other end of the directional flexible connecting tube 300 by magnetic connection, realizing the combination of quick replacement of cleaning head and heating function.

[0044] The application principle of the magnetic connection method in this application embodiment is as follows: Figure 3 As shown. This magnetic connection consists of an active end, namely the heat-conducting pile 310, and a passive end, namely the magnetic connection assembly 420. Its working principle is as follows:

[0045] Based on the attraction between the magnetic chuck 320 and the magnetic sheet 422, the magnetic chuck 320 generates a strong magnetic field. The magnetic sheet 422, made of materials such as low-carbon steel, has high magnetic permeability to the magnetic field, forming a low magnetic resistance path and thus generating a strong adsorption force. When the user brings the cleaning actuator 400 close to the end of the directional flexible connecting tube 300, even without precise alignment, the strong magnetic force between the magnetic chuck 320 and the magnetic sheet 422 will automatically generate a pulling force. This force guides the inner cavity of the heat-conducting connector 421 to automatically tighten and attract the heat-conducting pile 310, achieving initial self-alignment and pre-connection. This makes the connection operation very intuitive and convenient.

[0046] The outer diameter of the heat-conducting stud 310 is designed to be slightly larger than the inner diameter of the heat-conducting connector 421. With the aid of magnetism, the user applies a slight axial thrust, forcing the heat-conducting stud 310 into the inner cavity of the heat-conducting connector 421. Due to the interference fit, significant static friction and radial pressure are generated between the two. This constitutes the primary mechanical connection force, sufficient to resist the torsional, bending, and pulling forces generated during cleaning, preventing the cleaning head 410 from loosening or falling off during operation.

[0047] Furthermore, the interference fit not only provides a mechanical connection, but more importantly, it eliminates the air gap between the heat-conducting post 310 and the heat-conducting connector 421. Air is a poor conductor of heat, and gaps severely impede heat transfer. The enormous contact pressure generated by the interference fit ensures a tight fit between the metal parts, forming a highly efficient heat conduction path with extremely low thermal resistance. This allows the heat generated by the heating element 500 to be transferred almost without loss from the heat-conducting post 310 to the heat-conducting connector 421, and then rapidly conducted to the entire cleaning head 410.

[0048] In summary, the magnetic connection method in this embodiment not only achieves convenient and quick connection, but also forms a firm and reliable thermo-mechanical connection interface, which greatly satisfies the dual core requirements of special cleaning tools for "quick replacement" and "efficient heating".

[0049] Furthermore, the other end of the directional flexible connecting tube 300 is provided with a heat-conducting post 310; the cleaning execution component 400 includes a cleaning head 410 and a magnetic connection assembly 420; the magnetic connection assembly 420 is fixedly disposed at the base of the cleaning head 410; the magnetic connection assembly 420 includes a heat-conducting connecting seat 421 and a magnetic sheet 422 fixedly disposed at the bottom of the heat-conducting connecting seat 421; the heat-conducting connecting seat 421 has an inner cavity for accommodating the heat-conducting post 310, the heat-conducting post 310 is interference-fitted with the inner cavity, and the end of the heat-conducting post 310 is embedded with a magnetic attracting element 320 that attracts each other to the magnetic sheet 422.

[0050] It should be noted that, as shown in the attached document... Figure 4 , 5 The figures shown are cross-sectional schematic diagrams of the heat-conducting pile and the cleaning execution component, respectively, in one embodiment of this application. In this embodiment, the heat-conducting pile 310 can be a cylinder made of brass or aluminum alloy, and the magnetic suction component 320 can be two strong magnets, such as neodymium iron boron. The heat-conducting connecting seat 421 can be a cup-shaped body with a bottom made of a highly thermally conductive metal, such as brass, and the magnetic sheet 422 can be a magnetically conductive steel sheet, but these are not limited to these examples.

[0051] In this application, the directional flexible connecting tube 300 further includes: a metal serpentine tube 330, and an insulating and heat-conducting layer 340 wrapped around the outside of the metal serpentine tube 330; wherein, the heating element 500 is disposed between the metal serpentine tube 330 and the insulating and heat-conducting layer 340.

[0052] It should be noted that, as shown in the attached document... Figure 6 The diagram shown is a cross-sectional schematic of a directional flexible connecting tube according to an embodiment of this application. In this embodiment, the body material of the directional flexible connecting tube 300 is a metal snake-bone tube 330 that can be arbitrarily bent and shaped. Specifically, it is composed of a series of interconnected metal joints, or "joints," which are connected by ball joints and cup seats, or by slidable metal cables. This structure allows it to withstand large bending moments in any direction, and after the external force is removed, it can stably maintain its bent shape due to the static friction between the joints. Stainless steel or spring steel is typically chosen as the material to ensure its fatigue strength and corrosion resistance.

[0053] In this embodiment, the metal snake tube 330 is responsible for reliably transmitting the pushing, pulling, twisting and other operating forces from the drive handle 100 to the cleaning execution component 400 and enabling it to be accurately positioned.

[0054] In this embodiment, the heating element 500 is preferably a resistance wire or a flexible thin-film heating element, which is tightly wound, attached, or embedded in the outer surface of the metal serpentine tube 330. This wiring method ensures that stress concentration and breakage will not occur when the serpentine tube is repeatedly bent. It converts electrical energy into heat energy, which is transferred directly to the metal serpentine tube 330 through thermal conduction and also heats the surrounding area through thermal radiation.

[0055] The insulating and thermally conductive layer 340 is a high-temperature resistant insulating and thermally conductive material, such as addition-cured thermally conductive silicone rubber, which is tightly wrapped around the metal snake tube 330 around the heating element 500 by extrusion molding or molding process to form a complete, sealed, and flexible tubular outer layer. This material has both good electrical insulation and high thermal conductivity.

[0056] In this embodiment, the insulating and heat-conducting layer 340 completely isolates the charged heating element 500 from the external environment, preventing electric shock to the operator and ensuring safe use. Furthermore, it efficiently transfers the heat generated by the heating element 500 and the metal snake tube 330 to the outside of the tube, ultimately converging it at the cleaning head 410 via the heat-conducting pile 310, while simultaneously making the temperature distribution within the tube more uniform and preventing localized overheating. In addition, the insulating and heat-conducting layer 340 also protects the internal precision metal snake tube (330) and heating element (500) from moisture, chemical solvent corrosion, and physical scratches, extending the service life of the entire cleaning device by protecting the internal core components.

[0057] In this application, the heat-conducting pile 310 is provided with a metal protective shell 311 on its exterior; the metal protective shell 311 covers the sidewalls and base of the heat-conducting pile 310 except for the ends.

[0058] It should be noted that in this embodiment, the metal protective shell 311 can be made of 304 stainless steel by stamping or spinning process. Its shape is a cup-shaped structure with an open top, which tightly covers the side wall and base of the heat conduction pile 310 and exposes its top working end face completely.

[0059] Preferably, a gap may be reserved between the metal protective shell 311 and the internal heat-conducting pile 310, and the gap may be filled with high-temperature resistant heat-insulating material.

[0060] It should be noted that 304 stainless steel possesses excellent mechanical strength and hardness, providing a robust "armor" for the relatively softer internal heat-conducting pile 310, similar to brass. This effectively resists scratches and collisions with the bottle wall during use, preventing deformation or damage to the heat-conducting pile and extending the service life of the core component. Furthermore, the metal protective shell 311 encases the high-temperature heat-conducting pile 310, with its outer surface temperature significantly lower than that of the internal heat-conducting pile. This greatly reduces the risk of burns from accidental contact by the operator, improving product safety, and also enhances the efficiency of heat transfer, enabling rapid heating and reducing unnecessary energy consumption.

[0061] In this application, a first heat insulation layer is filled between the heat-conducting pile 310 and the magnetic suction member 320; a second heat insulation layer is filled between the magnetic suction member 320 and the metal protective shell 311.

[0062] It should be noted that the first and second heat insulation layers can be made of high-temperature resistant heat insulation materials, such as ceramic fiber cotton or aerogel felt, to form an effective heat insulation layer. In this embodiment, the first heat insulation layer forms a thermal resistance, which greatly prevents heat from being directly conducted from the high-temperature heat-conducting pile to the magnetic component, maintaining the working environment temperature of the magnet within a safe range, thereby ensuring the long-term reliability and service life of the magnetic connection; the second heat insulation layer effectively blocks the heat from the heat-conducting pile 310 and the heat generated by the magnet itself due to eddy currents from being transferred to the outer surface of the protective shell, significantly reducing the risk of burns and improving product safety.

[0063] In this application, the cleaning head 410 includes at least one of a scraper-type brush head, a high-temperature resistant steel wire brush head, and a chemical solvent resistant fiber brush head.

[0064] It should be noted that in actual cleaning scenarios, the three brush heads in this embodiment can form an efficient and progressive cleaning process:

[0065] First stage coarse cleaning: Using a scraper-type brush head, with the aid of heating, remove most of the large, hard, hardened residue.

[0066] The second stage is a thorough cleaning: the brush head is replaced with a high-temperature resistant steel wire brush to scrub away any remaining adhesive residue and stubborn stains, resulting in a preliminarily clean surface.

[0067] The third stage is fine cleaning: Finally, a chemical solvent-resistant fiber brush head is used, which can be selectively combined with a very small amount of solvent, to thoroughly polish and clean the inside of the bottle to achieve the required cleanliness for the experiment.

[0068] The heated cleaning device with a flexible and quick-replaceable cleaning head described in this application can flexibly handle various cleaning challenges, from the most stubborn to the most delicate, achieving the powerful function of "one machine for multiple uses and full coverage".

[0069] In this application, the magnetic connection assembly 420 further includes a high-temperature resistant housing; the high-temperature resistant housing covers the exterior of the heat-conducting connection base 421 and the magnetic sheet 422.

[0070] It should be noted that the high-temperature resistant outer shell in this embodiment can be made of high-temperature resistant plastic materials, such as PPS polyphenylene sulfide, PEI polyetherimide, etc., and is encapsulated on the outside of the thermally conductive connector 421 and the magnetic sheet 422 through injection molding to form an integrated component. This effectively blocks heat transfer to the outside, keeping the outer surface temperature within a safe range, fundamentally preventing the risk of burns to the operator and improving the inherent safety of the product. In addition, the outer shell completely isolates the internal metal components, thermally conductive connector, and magnetic sheet from the external environment, providing a reliable electrical insulation barrier. This avoids the risk of leakage that may occur in humid environments or under accidental conditions, ensuring the electrical safety of the entire device.

[0071] In addition, there is an electric heating element 500, which is disposed inside the directional flexible connecting pipe 300, and its heating part is thermally connected to the heat-conducting pile 310.

[0072] In this application, the heating element 500 includes a heating wire 510; the heating wire 510 is wound around the wall of the heat-conducting pile 310.

[0073] It should be noted that the heating wire 510 in this embodiment is preferably made of materials such as nickel-chromium alloy wire or iron-chromium-aluminum alloy wire. These materials have the characteristics of high resistivity, resistance to high-temperature oxidation, high strength at high temperatures, and long service life, making them very suitable as heating elements. The heating wire 510 is tightly and evenly wound on the lower part or a specific area of ​​the wall of the heat-conducting pile 310. To ensure insulation, a high-temperature resistant insulating coating, such as a ceramic coating, can be applied to the winding part of the heat-conducting pile 310 before winding, or a thin-walled ceramic tube or fiberglass sleeve can be placed on its outside, and these are not limited to these methods.

[0074] In this embodiment, the two ends of the heating wire 510 are connected to the power drive module 143 inside the drive handle 100 via high-temperature resistant leads, such as silicone wires, forming a complete circuit. Furthermore, to ensure that the heating wire 510 does not loosen during repeated heating and cooling and equipment movement, a high-temperature resistant adhesive, such as silicone, can be used to fix it to the outside of its winding layer, or high-temperature resistant fiber rope can be used for binding, ensuring close contact between it and the wall of the heat-conducting pile 310.

[0075] The heating element of the heating wire 510, which is the part wrapped around the wall of the heat-conducting pile 310, achieves maximum contact area with the metal wall of the heat-conducting pile 310 through the aforementioned tight winding and fixing method, thus realizing efficient surface contact thermal connection. After heat is generated, it is directly transferred to the heat-conducting pile 310 through heat conduction.

[0076] In summary, this embodiment of the application achieves comprehensive, all-around coverage of the cleaning head on laboratory equipment, especially the spherical inner wall, bottom, and narrow side neck of a three-necked flask, through the directional flexible connecting tube 300; it achieves quick assembly and disassembly and stable connection of the cleaning actuator 400 through a composite structure of magnetic connection and interference fit; and it achieves efficient softening of stubborn adhesive residues by directly heating the heat-conducting pile 310 through the heating element 500. Ultimately, it achieves a highly efficient, environmentally friendly, safe, and non-damaging cleaning effect for the equipment, solving the technical problem of difficult removal of polyurethane adhesives after they have cured inside a three-necked flask.

[0077] Example 2:

[0078] To address the aforementioned technical problems, this application also provides operational steps for cleaning a three-necked flask using a heated cleaning device in a practical application scenario, as follows:

[0079] Depending on the nature of the residual adhesive in the three-necked flask, such as large pieces of hard adhesive, viscous soft adhesive, or fine adhesive residue, select the appropriate cleaning head 410 from scraper-type brush heads, high-temperature resistant steel wire brush heads, and chemical solvent resistant fiber brush heads.

[0080] Holding the drive handle 100, bring the selected cleaning execution component 400 close to the heat-conducting post 310 at the end of the directional flexible connecting tube 300. Guided by the magnetic force of the magnetic suction member 320 and the magnetic sheet 422, align the inner cavity of the heat-conducting connecting seat 421 and fit it onto the heat-conducting post 310, gently pushing it in until the two are tightly connected through an interference fit.

[0081] Next, the operator turns on the switch panel 110 on the drive handle 100 to start the device. A suitable operating temperature is set via the temperature control panel 120; for example, for polyurethane residue, it can be set to 120-150 degrees Celsius. The operator observes the display panel 130 and waits for the system to heat up. Heat is generated by the heating element 500 and efficiently transferred to the cleaning head 410 via the heat conduction post 310 and the heat conduction connector 421.

[0082] Then, insert the heated cleaning head 410 into the three-necked flask through the main neck. Bend and shape the directional flexible connecting tube 300 by hand to conform to the spherical curve of the flask body, guiding the cleaning head 410 to areas with residual adhesive, such as the bottom or walls of the flask.

[0083] If the spherical bottle body and bottom need to be targeted, the residual adhesive is preheated and softened. Then, appropriate pressure is applied and the handle 100 is moved to remove the softened residual adhesive using the mechanical action of the cleaning head 410, such as scraping or brushing. If the inside of the side neck needs to be targeted, the directional flexible connecting tube 300 is bent to a suitable angle to precisely insert the cleaning head 410 into the narrow side neck. The heating and mechanical cleaning process is repeated to ensure thorough cleaning without any blind spots.

[0084] If there are various types of residual adhesive or if fine cleaning is required, the cleaning actuator 400 can be pulled out directly, and other types of cleaning heads 410 can be replaced using the quick-release function of the magnetic connection. For example, first use a scraper-type brush head to remove large pieces of hard adhesive, then switch to a high-temperature resistant steel wire brush head to scrub away residual adhesive stains, and finally use a chemical solvent-resistant fiber brush head for polishing and fine cleaning. If necessary, a small amount of solvent can also be used.

[0085] Finally, after cleaning, turn off the switch on the drive handle 100 to disconnect the power. After the device has cooled down, remove the cleaning actuator 400, clean it together with the drive handle 100, the connecting rod 200, and the directional flexible connecting tube 300, and store them properly.

[0086] In summary, the heated cleaning device of this application significantly reduces the adhesion strength of residual adhesive through heating and softening, making removal easy; it also allows the cleaning head to reach areas inaccessible by traditional tools through flexible orientation; and it achieves multi-purpose functionality through quick head replacement, flexibly addressing various cleaning needs. The entire process is efficient, environmentally friendly, and safe, significantly improving laboratory work efficiency while protecting expensive glassware.
