[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0028] Referring to Figure 1-2 , the present invention proposes an automatic cleaning and drying device for laboratory glassware, including a first box body 1, the inner cavity of which is divided into several working intervals by partition boards 2 fixed at equal intervals, and a lifting mechanism is arranged in each interval. The cleaning box 3 is installed on the top of the lifting mechanism, and a cleaning and drying mechanism is carried on the top. The second box body 4 is fixed above the first box body 1, and a placing component is built-in for fixing the experimental utensils in an inverted manner. The box cover 5 is connected to the second box body 4 through a support component. The waste water recovery component is communicated with the second box body 4 to realize the collection of waste liquid.

[0029] Among them, the partition boards 2 are fixedly connected at equal intervals to form a plurality of independent working units. The lifting mechanism can adopt a linear drive structure with a track 6 and a slider 7, such as a bidirectional screw 10 cooperating with a gear drive, to realize the vertical displacement of the cleaning box 3. The cleaning and drying mechanism includes a high-pressure spray head and a three-way valve pipeline. For example, a circumferential spray head can generate a rotating water flow to wash the inner wall. The placing component includes an opening support plate. For example, placing holes with adjustable diameters are adapted to utensils of different calibers. The waste water recovery component is designed with an inclined bottom surface and a diversion groove. For example, a 5° inclination angle is set to promote the collection of waste liquid.

[0030] Specifically, after the experimental vessel is inverted into the placement hole of the second box body 4, the box cover 5 is closed to form a sealed space. The lifting mechanism drives the cleaning box 3 to rise, so that the cleaning and drying mechanism extends into the interior of the vessel. High-pressure water flow flushes the residues on the inner wall through the circumferential nozzle, and then the air pump switches to the hot air mode for drying. Each working area operates independently and can process multiple vessels synchronously. The waste water flows into the recovery pipe through the diversion groove and is transported by the pump to the waste water tank for centralized treatment. The support assembly uses a link mechanism to maintain the opening angle of the box cover 5. For example, a human-shaped hinge structure provides stable support.

[0031] With such a design, the device realizes batch processing through independent control of different zones, solving the efficiency bottleneck of manual cleaning one by one. High-pressure spraying replaces brush contact, avoiding volumetric errors caused by damage to the vessels. The modular design supports the adaptation of vessels of different sizes. For example, the application range can be expanded by replacing the aperture of the placement plate. The waste water recovery system is integrated with the cleaning process, reducing environmental pollution in the laboratory.

[0032] Through the above technical solutions, the present invention realizes the full-automatic cleaning and drying of laboratory glass vessels, significantly improving the cleaning efficiency and consistency. Non-contact cleaning ensures the integrity of the vessel surface and avoids human operation errors. Parallel processing in multiple working areas shortens the overall operation time, and the integrated waste water recovery system optimizes the experimental environment. This device is particularly suitable for testing laboratories that need to clean various specifications of vessels frequently, solving the contradiction that traditional methods are difficult to balance efficiency and quality.

[0033] The present invention further proposes that the lifting mechanism includes a track 6, the track 6 is fixedly connected to the bottom of the working area, symmetrically sliding-connected with sliders 7 on the track 6, the top of the sliders 7 are respectively hinged with hinge arms 8, the top of the hinge arms 8 is hinged to the bottom surface of the cleaning box 3, and the two groups of hinge arms 8 are arranged at an angle. A fixed block 9 is fixedly connected to the middle position of the track 6, a bidirectional screw 10 is horizontally rotatably connected to the fixed block 9, both ends of the bidirectional screw 10 respectively pass through the two groups of sliders 7 and are in threaded cooperation with the sliders 7, a driven gear 11 is fixedly connected to the bidirectional screw 10, a driving motor is fixedly connected to the side of the fixed block 9, the output shaft of the driving motor is fixedly connected with a driving gear, and the driving gear meshes with the driven gear 11. The driven gear 11 is rotatably connected to the fixed block 9.

[0034] Among them, the track 6 refers to the guide structure that carries the movement of the slider 7, which can be specifically implemented by a linear metal guide rail to limit the slider 7 to move only along a single axial direction. The slider 7 refers to the load-bearing component that slides along the track 6, which can be specifically implemented by a metal block with a sliding groove, and a support structure is formed by a symmetrical arrangement. The articulated arm 8 refers to the force transmission rod connecting the slider 7 and the cleaning box 3, which can be specifically implemented by a stainless steel connecting rod in conjunction with an articulated shaft, and a height adjustment function is formed by changing the angle between the two sets of articulated arms 8. The bidirectional screw 10 refers to a threaded rod that drives the slider 7 to move in the opposite direction, which can be specifically implemented by a metal screw with a combination of positive and negative thread segments, and the rotational motion is converted into a linear displacement of the slider 7. The driven gear 11 and the driving gear refer to meshing gear pairs that transmit power, which can be specifically implemented by modulus-matched helical gears, and the screw is driven to rotate by the output power of the motor.

[0035] Specifically, when the driving motor is started, it drives the driving gear to rotate, and the driven gear 11 rotates synchronously through the gear meshing transmission, thereby driving the bidirectional screw 10 to rotate around its own axis. Since the two ends of the bidirectional screw 10 are respectively threaded with the two sets of sliders 7, when the screw rotates, it pushes the two sets of sliders 7 to slide in opposite directions along the track 6. The movement of the slider 7 drives the angle between the two sets of articulated arms 8 to change, thereby changing the vertical height of the connection point between the top of the articulated arm 8 and the cleaning box 3. By controlling the direction and speed of the driving motor, the lifting movement of the cleaning box 3 can be realized, so that it can adapt to the cleaning needs of experimental vessels of different heights.

[0036] With such a design, conventional cleaning devices mostly adopt a fixed support structure or a single hydraulic cylinder lifting method, which has the defects of limited adjustment range or excessive space occupation. This solution drives the symmetrical slider 7 to move in the opposite direction through a bidirectional screw 10, combined with the connecting rod structure of the articulated arm 8, to achieve smooth lifting of the cleaning box 3 in a limited space, and at the same time has a self-locking function to prevent displacement.

[0037] Through the above technical solution, the present invention can automatically adjust the working position of the cleaning mechanism according to the actual height of the experimental vessel, ensure that the annular high-pressure nozzle 13 accurately extends into the vessel for washing, and avoid the cleaning blind area or liquid splashing caused by height mismatch. The combined structure of the bidirectional screw 10 and the gear transmission can accurately control the lifting stroke, and the symmetrical slider 7 design effectively disperses the load pressure and prolongs the service life of the equipment.

[0038] The present invention further proposes that the cleaning and drying mechanism includes a high-pressure pipe 12, which is fixed on the top of the cleaning box 3. A circumferential high-pressure nozzle 13 is installed on the top of the high-pressure pipe 12, and a three-way valve is installed on the bottom of the high-pressure pipe 12. One of the ports of the three-way valve is connected to the cleaning box 3 through a water pipe, a water pump is installed on the water pipe, and the other port of the three-way valve is connected to the air pump.

[0039] Among them, the high-pressure pipe 12 refers to a rigid pipe used to transport cleaning liquid or gas, which can be made of stainless steel or corrosion-resistant plastic specifically. The circumferential high-pressure nozzle 13 provided at its top can be evenly distributed with spray holes around the pipe circumference to achieve multi-angle flushing. The three-way valve refers to a valve with three fluid passages, and an electromagnetic three-way valve can be specifically used to realize the switching control of the cleaning liquid and gas. The cleaning liquid is pumped from the cleaning tank 3 into the high-pressure pipe 12 through a water pump, or compressed air or hot air is introduced into the high-pressure pipe 12 through an air pump. The water delivery pipe refers to the pipe connecting the three-way valve and the cleaning tank 3, which can be specifically connected with a flexible hose and a clamp. The water pump can use a centrifugal pump or a diaphragm pump to realize liquid transportation. The air pump refers to a device that generates compressed air or hot air, and a scroll air compressor or an electric heating blower can be specifically used. Fast drying after cleaning is realized through the switching of the three-way valve.

[0040] Specifically, when the cleaning operation is started, the water pump pumps the cleaning liquid in the cleaning tank 3 into the three-way valve through the water delivery pipe, and transports it to the circumferential high-pressure nozzle 13 through the high-pressure pipe 12 to form a high-pressure water flow, so as to perform a full-round flushing on the inner wall of the inverted glassware. After the cleaning is completed, the three-way valve is switched to the air pump path, and the compressed air or hot air is sprayed out from the circumferential high-pressure nozzle 13 through the high-pressure pipe 12 to blow and dry the inside of the ware. No manual intervention is required during this process, and the automatic switching of the cleaning and drying processes is realized by programming the control of the three-way valve.

[0041] With such a design, traditional manual brush cleaning requires individual operations and there are cleaning dead corners, while the circumferential high-pressure nozzle 13 can cover the entire inner surface of the ware through multi-angle spraying, avoiding scratches caused by physical contact. In the prior art, cleaning and drying need to be carried out in separate steps, while in this solution, through the coordinated work of the three-way valve and the air pump, seamless connection of the cleaning and drying processes is realized, significantly improving the operation efficiency.

[0042] Through the above technical solution, the present invention solves the problem that it is difficult to thoroughly remove the residues on the inner wall of glassware. Using high-pressure fluid flushing to replace physical friction not only avoids damage to the ware but also improves the cleaning effect. Adopting a switchable cleaning and drying mode, all processing procedures are completed in a single device, reducing manual intervention and improving processing consistency, especially suitable for batch processing of precision glassware of different specifications.

[0043] The present invention further proposes that the placement assembly includes a first support plate 14, a second support plate 15 and a support rod 16. The first support plate 14 and the second support plate 15 are arranged opposite to each other. The support rod 16 passes through the second support plate 15 and the first support plate 14 and is perpendicularly arranged with respect to the first support plate 14. Placement holes are respectively formed on the first support plate 14 and the second support plate 15, and the placement holes on the first support plate 14 are arranged in one-to-one correspondence with the placement holes on the second support plate 15. The experimental ware is placed in the placement holes.

[0044] Among them, the first support plate 14 refers to the basic load-bearing component for supporting the bottom of the experimental vessel. Specifically, it can be implemented by a metal plate or an engineering plastic plate with positioning holes, and anti-slip textures can be set on its surface to increase friction. The second support plate 15 refers to the auxiliary positioning component that cooperates with the first support plate 14 to clamp the vessel. Specifically, it can adopt a structure made of the same material as the first support plate 14, and a clamping space is formed through symmetric arrangement. The support rod 16 refers to a rigid connecting piece for adjusting the distance between the two support plates. Specifically, it can be implemented by a threaded rod or a slide rod with a locking mechanism, which is convenient for adapting vessels of different heights. The placement hole refers to a circular or irregular through-hole penetrating the support plate. Specifically, a stepped edge structure can be set so that the necks of vessels with different calibers are embedded in the hole to form an inverted hanging state.

[0045] Specifically, after the experimental vessel is inverted, its open end is inserted into the placement hole of the first support plate 14, and the bottom of the vessel abuts against the edge of the placement hole at the corresponding position of the second support plate 15. The support rod 16 passes through the two support plates and the distance between them is fixed by a thread or a locking device. When cleaning vessels of different sizes, the support rod 16 can adjust the distance between the two support plates so that the placement holes on the first support plate 14 and the placement holes on the second support plate 15 are coaxially aligned, ensuring that the vessel remains vertical when inverted. For example, the slender neck of a volumetric flask can be embedded in a placement hole with a smaller aperture, while the wide mouth of a beaker can be adapted to a placement hole with a larger aperture, and double fixation is formed through the coordinated action of the two support plates.

[0046] With such a design, traditional cleaning devices usually adopt a single support frame or a fixed fixture, which cannot adapt to various vessel sizes and lack the vertical positioning function, resulting in the vessel shaking or tilting during the cleaning process. This solution uses a double-layer support plate with adjustable spacing and corresponding placement holes, so that vessels of different specifications can maintain a stable vertical posture in the inverted state, avoiding spray dead angles or mechanical collisions caused by vessel offset when the cleaning mechanism comes into contact.

[0047] Through the above technical solutions, the present invention realizes the precise positioning and reliable fixation of laboratory vessels during the cleaning process, solves the problem of cleaning blind spots caused by vessel shaking during manual cleaning, and at the same time avoids scratches caused by the robotic arm forcibly contacting the inner wall of the vessel, ensuring the accurate execution of the cleaning action.

[0048] The present invention further proposes that the wastewater recovery component includes a recovery pipe and a wastewater tank. The bottom surface of the second box body 4 is set as an inclined surface, and a plurality of diversion grooves are arranged on the inclined surface. A confluence groove is opened at the low end of the inclined surface, and the confluence groove and the diversion grooves are arranged vertically. One end of the recovery pipe passes through the second box body 4 and is communicated with the confluence groove, the other end of the recovery pipe is communicated with the wastewater tank, and a recovery pump is installed on the recovery pipe.

[0049] Among them, the inclined plane means that the bottom surface of the second box body 4 is of an inclined structure, for example, arranged at an inclined angle of 5° to 15°, and can be specifically formed by steel plate stamping or welding processes. Its function is to guide the wastewater to flow towards the lower end. The diversion groove refers to a strip-shaped sunken drainage channel opened on the inclined plane, for example, with a V-shaped or U-shaped cross-section, and can be specifically formed by machining or die forming. Its function is to disperse and guide the wastewater to the lower end of the inclined plane. The confluence groove refers to a water collecting tank arranged at the lower end of the inclined plane and vertically connected to the diversion groove, for example, with a rectangular cross-section tank body, and can be specifically formed by cutting or casting processes. Its function is to centrally collect the dispersed wastewater. The recovery pipe refers to a tubular structure connecting the confluence groove and the wastewater tank, for example, made of PVC or metal pipes, and can be specifically connected by flanges or clamps. Its function is to transport the wastewater to the wastewater tank. The recovery pump refers to a power device that drives the flow of wastewater, for example, a centrifugal pump or a diaphragm pump, and can be specifically installed in the middle or at the end of the recovery pipe. Its function is to provide the power required for wastewater transmission.

[0050] Specifically, the bottom of the second box body 4 is designed with an inclined plane, so that the wastewater generated during the cleaning process naturally flows towards the lower end under the action of gravity. The diversion groove evenly disperses the wastewater onto the surface of the inclined plane to avoid local water accumulation. The confluence groove is arranged perpendicular to the diversion groove, concentrating the dispersed wastewater to the lowest point of the inclined plane, and the wastewater is transported to the external wastewater tank through the recovery pipe driven by the recovery pump. Thus, the whole process of wastewater generation, diversion, collection and recovery is realized automatically.

[0051] With such a design, traditional cleaning devices usually rely on manual dumping or simple drainage holes to discharge wastewater, which has the problems of low efficiency and easy residue. This solution through the collaborative design of the inclined plane, diversion groove and confluence groove enables the wastewater to complete directional flow and collection without external intervention. At the same time, the introduction of the recovery pump strengthens the reliability of wastewater transmission and avoids wastewater retention caused by pipeline blockage or insufficient flow.

[0052] Through the above technical solution, the present invention realizes the automatic recovery of wastewater during the cleaning process, effectively avoids secondary pollution caused by the residue of wastewater in the second box body 4, and at the same time reduces manual cleaning operations, ensuring the continuity and environmental cleanliness of the cleaning and drying process.

[0053] The present invention further proposes an automatic cleaning and drying device for laboratory glassware. Its support assembly includes a first connecting rod 17 and a second connecting rod 18. One end of the first connecting rod 17 is hinged to the side wall of the second box body 4, and the other end is hinged to the side wall of the box cover 5. One end of the second connecting rod 18 is slidably connected to the middle of the first connecting rod 17, and the other end is hinged to the side wall of the second box body 4. The first box body 1 and the second box body 4 are arranged in a human-shaped structure.

[0054] Among them, the first connecting rod 17 refers to a rigid rod that connects the box body and the box cover 5 in a hinged manner, which can be specifically implemented by a metal connecting rod or a composite material rod, and is used to transmit the force when the box cover 5 is opened and closed. The second connecting rod 18 refers to an auxiliary support rod 16 that forms a sliding fit with the first connecting rod 17, which can be specifically implemented by a telescopic rod with a slide groove or an adjustable buckle structure, which is used to adjust the support angle and enhance the structural stability. The human-shaped structure refers to the inclined support form formed between the first box body 1 and the second box body 4, which can be specifically implemented by adjusting the box body installation angle or matching the connecting rod length, and is used to disperse the vibration load when the device is running.

[0055] Specifically, when the box cover 5 is opened, the first connecting rod 17 rotates around the hinge point of the side wall of the second box body 4, driving the box cover 5 to lift up. At this time, the second connecting rod 18 moves along the slide rail in the middle of the first connecting rod 17, and limits the displacement range by the hinge point with the second box body 4, so that the first connecting rod 17 and the second connecting rod 18 form a dynamic angle. As the opening and closing angle of the box cover 5 changes, the sliding position of the second connecting rod 18 is automatically adjusted to ensure that the support assembly always maintains a triangular force structure. The human-shaped layout between the first box body 1 and the second box body 4 further strengthens the mechanical balance of the overall device, avoiding the accidental closing of the box cover 5 due to the shaking caused by the movement of the cleaning mechanism.

[0056] With such a design, the existing cleaning device's cover 5 support mostly adopts a single connecting rod or a fixed buckle structure, which cannot adapt to the force requirements under different opening and closing angles and is prone to support failure due to vibration. The present invention achieves a balance between support rigidity and flexibility through a slidably adjustable double connecting rod combined with a human-shaped box layout, and can still maintain a stable support state under dynamic conditions.

[0057] Through the above technical solution, the present invention solves the problem that the support structure of the box cover 5 is easy to loosen or get stuck in a vibrating environment, ensuring that the box cover 5 is always in a safe open position during the cleaning process, while avoiding the risk of operation interruption or equipment damage due to support failure.

[0058] The present invention further proposes that a sealing plug 19 is fixedly connected to the outer wall of the high-pressure pipe 12, and the top of the first box body 1 and the bottom of the second box body 4 are respectively provided with through holes, and the sealing plug 19 is inserted into the through holes.

[0059] Among them, the sealing plug 19 refers to an elastic sealing component wrapped around the outer wall of the high-pressure pipe 12, which can be made of rubber or silicone material, and is sealed and connected with the perforation through interference fit. Its function is to prevent liquid or gas from leaking from the box connection during cleaning or drying.

[0060] Among them, the perforation refers to a through hole opened at the top of the first box body 1 and the bottom of the second box body 4, which can be formed by mechanical processing. The aperture size can be slightly smaller than the outer diameter of the sealing plug 19. Its function is to provide a through channel for the high-pressure pipe 12, and at the same time, the sealing isolation between the boxes is achieved through the compression deformation of the sealing plug 19.

[0061] Specifically, the high-pressure pipe 12 extends upward through the top of the cleaning box 3, and passes through the perforations at the top of the first box body 1 and the bottom of the second box body 4 in sequence. The sealing plug 19 is fixed to the outer wall of the high-pressure pipe 12. When the high-pressure pipe 12 is inserted into the perforation, the sealing plug 19 fits tightly with the inner wall of the perforation due to elastic deformation to form a closed structure. As a result, when the cleaning liquid or drying gas enters the interior of the experimental vessel through the high-pressure pipe 12, no leakage will occur at the connection between the boxes, ensuring that the cleaning and drying processes are carried out in a closed environment. At the same time, the compression deformation of the sealing plug 19 can adapt to the position change of the high-pressure pipe 12 during the lifting process, avoiding sealing failure due to displacement.

[0062] With such a design, the connection between the pipe and the box in the traditional cleaning device usually adopts a fixed sealing ring or a direct through-type design. The former is prone to wear and leakage due to friction in the dynamic lifting scene, and the latter cannot isolate the liquid or gas from interpenetration between the boxes. This solution maintains sealing during dynamic lifting through the elastic cooperation of the sealing plug 19 and the perforation, while isolating the working medium between different boxes, preventing cleaning wastewater from infiltrating into the drying area or external pollutants from entering the cleaning area.

[0063] Through the above technical scheme, the present invention solves the problem of medium leakage or cross-contamination caused by insufficient sealing at the connection between the pipeline and the box body in the prior art, ensures that the cleaning liquid and drying gas only flow within the preset path, reduces resource waste, improves the stability and cleanliness of the cleaning and drying process, and avoids the cleanliness of the experimental vessel being affected by external contaminants.

[0064] The present invention further proposes that the box cover 5 is provided with a plurality of groups of abutment protrusions in an array, and the abutment protrusions abut against the experimental vessels respectively.

[0065] The abutment protrusion refers to a block structure installed on the inner side of the box cover 5, which can be made of elastic material, such as rubber or silicone, and fixed on the surface of the box cover 5 by molding or injection molding. When the box cover 5 is closed, it contacts the outer wall of the inverted experimental vessel to form a flexible support. This structure can prevent the vessel from being displaced due to mechanical vibration or water flow impact during the washing or drying process, and avoid scratches on the surface of the vessel caused by hard contact.

[0066] Specifically, when the lid 5 is closed, the array-distributed abutting bumps are elastically deformed to fit the outer walls of experimental vessels of different sizes, forming multiple-point contacts. For example, when cleaning a beaker, the abutting bumps can apply uniform pressure around the outer side of the beaker body; when cleaning a test tube, the abutting bumps are distributed along the axial direction of the tube body to restrict lateral movement. Since the abutting bumps are made of elastic materials, their contact pressure can be adaptively adjusted according to the shape of the vessel, ensuring both the fixing effect and avoiding excessive squeezing that may cause the vessel to break. When the cleaning and drying mechanism is working, the experimental vessels are stably constrained, preventing the nozzle alignment from shifting or the cleaning liquid from splashing out due to shaking.

[0067] With such a design, traditional cleaning devices usually lack a fixing structure for vessels and only rely on gravity placement or simple slot positioning, resulting in the vessels being prone to tipping or displacement under the impact of high-pressure water flow or air flow, affecting the cleaning effect. This solution realizes flexible fixing of vessels of different shapes through the array arrangement of elastic abutting bumps, solves the problem of unstable vessel positioning in the prior art, and at the same time avoids damage to the vessels that may be caused by rigid fixing structures.

[0068] Through the above technical solution, the present invention can effectively prevent the unexpected displacement of experimental vessels during the cleaning and drying processes, ensure that the nozzle is accurately aligned with the inner wall of the vessel, and improve the cleaning efficiency; the elastic contact method reduces the risk of damage to the vessels caused by mechanical collision, especially suitable for precision glass vessels with high requirements for surface integrity.

[0069] The present invention further proposes that there are several groups of abutting bumps arrayed on the lid 5, and the abutting bumps are respectively in contact with the experimental vessels.

[0070] Among them, the abutting bump refers to a convex structure fixed on the inner surface of the lid 5, which can be specifically realized by elastic material molding or machining methods, such as rubber, silicone or engineering plastic materials. This structure generates deformation when contacting the outer wall of the experimental vessel when the lid 5 is closed, forming a multi-point flexible support. The array arrangement means that multiple groups of abutting bumps are arranged in an equidistant or regular pattern adapted to the size of the vessel, and specifically, a rectangular array or a concentric circle array mode can be adopted to ensure that vessels of different sizes can be effectively fixed.

[0071] Specifically, when the lid 5 is closed, the top opening edge of the inverted glass vessel comes into contact with the abutting bumps. Since the abutting bumps are made of elastic materials and are in a point-contact form, they undergo local compressive deformation under pressure, forming a radial binding force and an axial buffering effect on the vessel. During this process, the vessel is restricted within a predetermined position range, preventing the vibration generated when the lifting mechanism drives the cleaning box 3 to move from causing the vessel to shift. At the same time, the arrayed abutting bumps can adapt to the fixing requirements of vessels with different diameters. For example, when processing slender vessels such as test tubes, at least two groups of abutting bumps can respectively form double-point constraints at the upper end and the middle of the vessel.

[0072] In some specific embodiments, the abutting protrusions can be designed as hemispherical contact surfaces to reduce pressure, such as a silicone hemisphere with a diameter of 5 mm. In another embodiment, a height adjustment mechanism can be provided at the base of the abutting protrusions, such as a threaded mounting post, to allow the protrusion length to be adjusted according to the height of the vessel. In addition, the spacing of the abutting protrusion array can be set to an adjustable spacing of 10-30 mm, and the relative positions of each group of protrusions can be adjusted by the sliding track 6.

[0073] With this design, traditional cleaning devices often use rigid buckles or fixing fixtures to fix utensils, which can easily lead to uneven clamping force due to poor size adaptability, and frequent assembly and disassembly can easily cause wear on the outer wall of the utensils. This solution uses an array design of elastic abutment bumps to ensure the reliability of fixation while avoiding the risk of damage caused by hard contact, and can adapt to utensils of various specifications without manual adjustment.

[0074] Through the above technical solution, the present invention realizes the stable positioning of the experimental vessel during the cleaning process, effectively prevents the displacement or tipping of the vessel caused by mechanical vibration, and ensures that the nozzle of the cleaning mechanism is always aligned with the inner cavity of the vessel. The elastic contact method avoids scratches on the surface of the vessel caused by rigid fixation, and the array layout improves the compatibility with vessels of different sizes and reduces the time consumption of manual adjustment and positioning.

[0075] The present invention further proposes that the box cover 5 is provided with a plurality of groups of abutment protrusions in an array, and the abutment protrusions abut against the experimental vessels respectively.

[0076] The abutting protrusions are protruding structures distributed on the inner surface of the box cover 5, which can be realized by molding elastic materials, such as rubber or silicone, and are used to contact the outer wall of the experimental vessel when the box cover 5 is closed to provide flexible support. This feature disperses pressure through multi-point contact to avoid damage to the vessel caused by rigid extrusion.

[0077] Specifically, during the closing process of the box cover 5, the abutting protrusions contact the outer surface of the inverted experimental vessel with the hinged movement to form multiple contact points. Since the abutting protrusions are made of elastic material, they can be deformed when in contact with the outer wall of the vessel, adapting to vessels of different diameters or shapes and maintaining stable clamping. For example, when cleaning a test tube, the abutting protrusions surround the outer wall of the test tube to form an annular constraint, and when handling a beaker, multiple abutting protrusions are distributed along the edge of the cup mouth to prevent the vessel from shifting due to the impact of water flow during the cleaning process.

[0078] With this design, traditional cleaning devices usually rely on fixed clamps or buckles to limit the position of the vessel, which makes it difficult to adapt to vessels of different sizes or shapes, and is prone to scratches on the surface of the vessel due to rigid clamping. This solution uses an array of elastically abutting bumps to achieve compatibility with vessels of multiple sizes and reduce the risk of vessel damage through flexible contact.

[0079] Through the above technical solution, the present invention solves the problem that the cleaning effect is uneven due to unstable fixation of the utensils during manual cleaning, and at the same time avoids the physical damage to the utensils caused by the rigid clamping structure, ensures that the utensils maintain a stable posture during the cleaning process, and improves the cleaning coverage and safety.
