Description

Technical Field

[0001] This utility model relates to the field of sealing structure technology, specifically a sealing structure for the chamber cover of a vertical pressure steam sterilization device. Background Technology

[0002] A vertical pressure steam sterilizer is a device specifically designed for the sterilization of medical devices. Through the action of high-temperature, high-pressure steam, it effectively kills bacteria, viruses, and other microorganisms. The vertical pressure steam sterilizer has several key features: First, it uses high-temperature, high-pressure steam sterilization to thoroughly kill various microorganisms, ensuring the sterilization effect of medical devices. Second, it has a large capacity, allowing for the simultaneous sterilization of multiple devices, improving work efficiency. Furthermore, its vertical design minimizes the footprint, making it convenient to place and use. The vertical pressure steam sterilizer mainly consists of a steam generator, a pressure control system, a temperature control system, a timer, and a safety valve. The steam generator produces high-temperature, high-pressure steam; the pressure and temperature control systems ensure the equipment operates within the set parameters; the timer sets the sterilization time; and the safety valve automatically releases pressure when it becomes too high, ensuring the equipment's safety. To guarantee sterilization effectiveness, the gap between the sealing cover and the sterilization cabinet must be sealed.

[0003] Chinese Utility Model Patent Publication No. CN219271653U discloses a steam sterilizer, relating to the field of steam sterilization technology. The sterilizer includes a workbench and a sterilization cylinder. The sterilization cylinder is fixedly mounted on the workbench, and a cylinder is fixedly mounted on the workbench. A mounting bracket is fixedly connected to the telescopic end of the cylinder, and a sealing cover for the sterilization cylinder is connected to the mounting bracket. A storage cylinder is detachably connected to the bottom of the sealing cover. A first air inlet pipe is connected to the bottom of the sterilization cylinder, and a second air inlet pipe is connected to the first air inlet pipe. The extension of the telescopic end of the cylinder can open the sealing cover and open the storage cylinder. The cylinder is removed from the sterilization cylinder, and the retraction of the cylinder's telescopic end closes the sealing cover, allowing the storage cylinder to be placed inside the sterilization cylinder for disinfection and sterilization. This facilitates the handling of objects to be sterilized without requiring manual opening and closing of the sealing cover, effectively preventing workers from being burned. However, while the above equipment can close the sealing cover and place the storage cylinder in the sterilization cylinder for sterilization, it lacks a structure to seal the gap between the sealing cover and the cylinder body. This can easily lead to the leakage of high-temperature gas, reducing the airtightness of the equipment. Therefore, we propose a sealing structure for the cover of a vertical pressure steam sterilization device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a sealing structure for the chamber cover of a vertical pressure steam sterilization device, thereby solving the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing structure for the cover of a vertical pressure steam sterilization device, comprising a body, an outer cylinder fixedly mounted on the top of the body, a connecting screw threadedly connected to the inner wall of the outer cylinder, an arc-shaped plate rotatably connected to the outer wall of the connecting screw, an adjusting screw at the top of the arc-shaped plate, a sealing component at the bottom of the adjusting screw, and a docking component at the top of the body; The sealing assembly includes a sealing cap, a pressure ring fixedly mounted on the inner wall of the sealing cap, and a sealing ring bonded to the inner wall of the sealing cap. Mounting holes are provided on the outer walls of both the sealing cap and the pressure ring. A branch pipe is fixedly mounted on the inner wall of the mounting hole. A fixing plate is fixedly mounted on the inner wall of the branch pipe. A diaphragm is also provided on the inner wall of the branch pipe. Electrode plates are fixedly mounted on the outer walls of both the diaphragm and the fixing plate. A fixing rod is fixedly mounted on the outer wall of the branch pipe. A controller, an audible alarm, and a warning light are fixedly mounted on the top of the fixing rod. A collection groove is provided between the pressure ring and the sealing ring. The docking assembly includes a connecting pipe, the top of which is respectively provided with a groove and a placement groove. A sealing ring II is placed on the inner wall of the placement groove. A fixing hole is provided on the inner wall of the groove. A pressure ring II is tightly fitted to the inner wall of the groove. A connecting screw II is provided on the top of the pressure ring II.

[0006] Through the above technical solution, the structure consisting of a main body, outer cylinder, connecting screw one, arc plate, adjusting screw, sealing component, and docking component allows the user to install sealing ring two in the placement groove during use. Utilizing the shape of sealing ring two, when the sealing cap is on, sealing ring one and the inner wall of sealing ring two fit tightly together. The pressure ring one presses against sealing ring two, forming a downward indentation. Furthermore, the bend between sealing ring one and sealing ring two forms a sealing structure, thus achieving the effect of isolating the interior of the main body from the outside. This double-sealing structure increases the sealing between the main body and the sealing cap, thereby improving the sealing performance of the sealing cap.

[0007] Preferably, the second pressure ring is fixedly connected to the connecting pipe via the second connecting screw, the bottom of the first pressure ring is tightly fitted to the top of the second sealing ring, and the second sealing ring is fixedly connected to the connecting pipe via the first pressure ring and the second pressure ring respectively.

[0008] Through the above technical solution, the design of the pressure ring two and the connecting screw two allows the sealing structure to use the pressure ring two to fix the connecting screw two during use. This ensures that the pressure ring two always compresses the sealing ring two, preventing the sealing ring two from detaching from the placement groove after installation, thereby improving the stability of the sealing ring two after installation. Preferably, the cross-sectional shape of the second sealing ring is "convex", and both the first sealing ring and the second sealing ring are made of rubber.

[0009] By using the above technical solution, and by setting the specific shape of the second sealing ring, the outer wall of the first sealing ring will fit against the inner wall of the second sealing ring after the first sealing ring is placed on the sealing cover. This achieves the effect of strengthening the sealing structure at the joint between the sealing cover and the main body. Combined with the pressure of the first pressure ring, the second sealing ring will be pressed to create an indentation at the joint between the second sealing ring and the first pressure ring, thus achieving a double sealing effect and ensuring the airtightness of the device during operation.

[0010] Preferably, the controller is electrically connected to the electrode plate, the audible alarm and the warning light respectively, and the fixing plate and the diaphragm are symmetrically arranged along the inner wall of the branch pipe.

[0011] Through the above technical solution, the electrode plates, controller, audible alarm, and warning light structure enable the sealing structure to prevent gas leakage during use. Air inside the main body first enters the collection tank through the gap between sealing ring one and sealing ring two. Since the branch pipe is connected to the collection tank, gas enters the branch pipe. Due to the increased air pressure, the diaphragm deforms, causing the two electrode plates to come into contact. This triggers the controller to automatically activate the audible alarm and illuminate the warning light to alert the user, ensuring timely maintenance of sealing ring two and sealing ring one. This improves the intelligence and automation of the sealing structure.

[0012] Preferably, the interior of the branch pipe is connected to the interior of the collection tank, and a miniature vacuum pump is provided on the outer wall of the branch pipe.

[0013] Through the above technical solution, the micro vacuum pump structure allows the air inside the collection tank to be extracted after the sealing cover is closed, thus ensuring that no air remains in the collection tank. This prevents false alarms from occurring with the audible alarm and warning light, thereby ensuring the normal operation of the device.

[0014] Preferably, the number of branch pipes is several, and the several branch pipes are evenly distributed along the outer wall of the sealing cover.

[0015] Through the above technical solution, by setting up several branch pipe structures, the sealing structure can be used to detect the sealing effect of sealing ring one and sealing ring two in segments through several branch pipes, thereby ensuring that the sealing structure can perform airtightness monitoring operations normally during use, and thus improving the practicality of the sealing structure.

[0016] Preferably, the outer wall of the first sealing ring is in close contact with the inner wall of the second sealing ring, and the first pressure ring is made of stainless steel.

[0017] Through the above technical solution, stainless steel has the characteristics of wear resistance and easy disinfection, which can reduce the erosion of pressure ring one by water molecules in high temperature steam, extend the service life of pressure ring one, and its material also has the characteristics of relatively low cost, reducing the production and maintenance costs of this sealing structure.

[0018] Compared with the prior art, this utility model provides a sealing structure for the chamber cover of a vertical pressure steam sterilization device, which has the following beneficial effects: 1. The sealing structure for the chamber cover of a vertical pressure steam sterilizer, through the configuration of a body, sealing cover, sealing ring one, sealing ring two, pressure ring one, pressure ring two, and groove structure, allows the sealing structure to fix sealing ring two in the placement groove using pressure ring one during use. Then, pressure ring one compresses sealing ring one to create an indentation, and the mating of sealing ring one and sealing ring two creates a bending structure, achieving a double sealing effect on the gap between the sealing cover and the body, thereby improving the sealing performance of the chamber cover of the vertical pressure steam sterilizer.

[0019] 2. The sealing structure for the chamber cover of the vertical pressure steam sterilization device, through the arrangement of branch pipes, diaphragms, fixing plates, electrode plates, fixing rods, controllers, audible alarms, warning lights, fixing holes, and collection grooves, allows the sealing structure to collect leaked gas from the main body during operation. The increased gas pressure in the branch pipes causes the diaphragm to deform, resulting in the two electrode plates coming into contact. This enables the controller to automatically activate the electronic components and trigger an alarm, improving the intelligence and automation of the sealing structure. Furthermore, during maintenance, the user can remove the second pressure ring to replace the second sealing ring, or directly open the sealing cover to remove the first sealing ring and attach a new one. This facilitates maintenance and improves user efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: like Figure 1-2 as well as Figure 5-7 As shown, the present invention provides a sealing structure for the cover of a vertical pressure steam sterilization device, including a body 1, an outer cylinder 2 fixedly mounted on the top of the body 1, a connecting screw 3 threadedly connected to the inner wall of the outer cylinder 2, an arc plate 4 rotatably connected to the outer wall of the connecting screw 3, an adjusting screw 5 at the top of the arc plate 4, a sealing component 6 at the bottom of the adjusting screw 5, and a docking component 7 at the top of the body 1. The sealing assembly 6 includes a sealing cover 601, a pressure ring 611 fixedly mounted on the inner wall of the sealing cover 601, a sealing ring 612 bonded to the inner wall of the sealing cover 601, mounting holes 602 on the outer walls of both the sealing cover 601 and the pressure ring 611, a branch pipe 603 fixedly mounted on the inner wall of the mounting hole 602, a fixing plate 605 fixedly mounted on the inner wall of the branch pipe 603, a diaphragm 604 on the inner wall of the branch pipe 603, electrode plates 606 fixedly mounted on the outer walls of both the diaphragm 604 and the fixing plate 605, a fixing rod 607 fixedly mounted on the outer wall of the branch pipe 603, a controller 608, an audible alarm 609, and a warning light 610 fixedly mounted on the top of the fixing rod 607, and a collection groove 613 between the pressure ring 611 and the sealing ring 612. The docking assembly 7 includes a connecting pipe 701. The top of the connecting pipe 701 is provided with a groove 702 and a placement groove 704. A sealing ring 616 is placed on the inner wall of the placement groove 704. A fixing hole 703 is provided on the inner wall of the groove 702. A pressure ring 614 is tightly fitted to the inner wall of the groove 702. A connecting screw 615 is provided on the top of the pressure ring 614.

[0024] The advantage is that, through the structure of the main body 1, outer cylinder 2, connecting screw 1 3, arc plate 4, adjusting screw 5, sealing component 6, and docking component 7, the user can install the sealing ring 2 616 in the placement groove 704 during use. Utilizing the shape characteristics of the sealing ring 2 616 itself, when the sealing cover 601 is on, the sealing ring 1 612 and the inner wall of the sealing ring 2 616 are tightly fitted, while the pressure ring 1 611 will press the sealing ring 2 616, forming a downward pressure indentation. Furthermore, the bend between the sealing ring 1 612 and the sealing ring 2 616 will form a sealing structure, thereby achieving the effect of isolating the interior of the main body 1 from the outside. The double-sealed structure increases the sealing structure between the main body 1 and the sealing cover 601, thereby improving the sealing performance of the sealing cover 601.

[0025] Specifically: the second pressure ring 614 is fixedly connected to the connecting pipe 701 through the second connecting screw 615, the bottom of the first pressure ring 611 is tightly fitted with the top of the second sealing ring 616, and the second sealing ring 616 is fixedly connected to the connecting pipe 701 through the first pressure ring 611 and the second pressure ring 614 respectively.

[0026] The advantage is that, through the structure of the pressure ring 614 and the connecting screw 615, the sealing structure uses the pressure ring 614 to fix the connecting screw 615 during use, so that the pressure ring 614 always presses the sealing ring 616, ensuring that the sealing ring 616 will not fall out of the placement groove 704 after installation, thereby improving the stability of the sealing ring 616 after installation.

[0027] Specifically: the cross-sectional shape of sealing ring 2 616 is "convex", and both sealing ring 1 612 and sealing ring 2 616 are made of rubber.

[0028] The advantage is that by setting the specific shape of the second sealing ring 616, the outer wall of the first sealing ring 612 will fit against the inner wall of the second sealing ring 616 after the sealing cover 601 is put on, thereby achieving the effect of strengthening the sealing structure at the junction of the sealing cover 601 and the main body 1. Combined with the pressure ring 611 pressing the second sealing ring 616, a dent is produced at the junction of the second sealing ring 616 and the pressure ring 611, achieving a double sealing effect, thereby ensuring the airtightness of the device during operation.

[0029] Example 2: like Figure 3-4 As shown, this is an improvement on the previous embodiment.

[0030] Specifically: the controller 608 is electrically connected to the electrode plate 606, the audible alarm 609 and the warning light 610 respectively, and the fixing plate 605 and the diaphragm 604 are symmetrically arranged along the inner wall of the branch pipe 603.

[0031] The advantage is that, through the structure of electrode plate 606, controller 608, audible alarm 609, and warning light 610, when a gas leak occurs during use, the air inside the main body 1 will first enter the collection tank 613 through the gap between sealing ring one 612 and sealing ring two 616. Since the branch pipe 603 is connected to the collection tank 613, the gas will enter the branch pipe 603. Due to the increase in air pressure, the diaphragm 604 will deform, causing the two electrode plates 606 to stick together. This will cause the controller 608 to automatically activate the audible alarm 609 to sound an alarm, and the warning light 610 to illuminate to warn the user. This ensures that the user can promptly inspect sealing ring two 616 and sealing ring one 612, thus improving the intelligence and automation of the sealing structure.

[0032] Specifically: the interior of branch pipe 603 is connected to the interior of collection tank 613, and a miniature vacuum pump is provided on the outer wall of branch pipe 603.

[0033] The advantage is that, through the design of the miniature vacuum pump structure, after the sealing cover 601 is closed, the miniature vacuum pump is used to extract the air inside the collection tank 613, thereby ensuring that no air remains in the collection tank 613. This prevents the audible alarm 609 and the warning light 610 from making false alarms, thus ensuring the normal use of the device.

[0034] Specifically: there are several branch pipes 603, and all of them are evenly distributed along the outer wall of the sealing cover 601.

[0035] The advantage is that by setting up several branch pipes 603, the sealing structure can detect the sealing effect of sealing ring 1 612 and sealing ring 2 616 in segments through several branch pipes 603, thereby ensuring that the sealing structure can perform airtightness monitoring operations normally during use, thus improving the practicality of the sealing structure.

[0036] Specifically: the outer wall of sealing ring 612 fits tightly against the inner wall of sealing ring 616, and the pressure ring 611 is made of 304 stainless steel.

[0037] The advantages are that 304 stainless steel is wear-resistant and easy to disinfect, which can reduce the corrosion of pressure ring 611 by water molecules in high-temperature steam, extend the service life of pressure ring 611, and its material also has the characteristic of relatively low cost, reducing the production and maintenance costs of this sealing structure.

[0038] Working principle: First, when installing the sealing structure, the user places the second sealing ring 616 in the placement groove 704, then places the second pressure ring 614 in the groove 702, ensuring the bottom of the pressure ring 614 fits tightly against the top of the second sealing ring 616. The pressure ring 614 is then fixed to the connecting pipe 701 using the connecting screw 615. At this time, the outer diameter of the pressure ring 614 presses down on the second sealing ring 616, fixing the sealing ring 616 to the connecting pipe 701. When the user covers the sealing cap 601, the first pressure ring 611 presses down on the second sealing ring 616, forming a dent, and the outer wall of the first sealing ring 612 fits tightly against the inner wall of the second sealing ring 616, forming a sealing structure. This achieves a double sealing structure to seal the gap between the connecting pipe 701 and the sealing cap 601, thereby improving the sealing performance of the sealing structure. Furthermore, this sealing structure... During operation, a miniature vacuum pump is used to extract air from the collection tank 613. When gas leaks inside the main body 1 due to wear or reduced sealing at the contact point of sealing ring 1 612 and sealing ring 2 616, the gas will first enter the collection tank 613. Because the dent cannot directly leak to the outside, the diaphragm 604 will deform due to the increased air pressure, causing the two electrode plates 606 to stick together. This causes the controller 608 to automatically control the audible alarm 609 to sound an alarm, and the warning light 610 to light up, thus ensuring that the user can promptly detect and handle the problem of the equipment. This improves the intelligence and automation of the sealing structure. During maintenance, the user can directly open the sealing cover 601, remove the pressure ring 2 614 to remove the sealing ring 2 616, or directly remove the sealing ring 1 612 on the sealing cover 601 to install a new sealing ring 1 612.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
