Description

Technical Field

[0001] This utility model relates to the field of sterilizer door technology, specifically to a structure for sealing sterilizer doors. Background Technology

[0002] The sterilizer door is a component in sterilization equipment used to open and close the sterilization chamber. Its core function is to enable the opening and closing of the chamber, ensuring the safe handling of items to be sterilized, and, in conjunction with the sealing structure, to create a closed space during sterilization. The sealing structure is a key component at the junction of the door and the sterilization chamber. Its function is to prevent the leakage of high-temperature steam, pressure, and other media inside the chamber through a tight seal between the seal and the door / chamber, while simultaneously preventing the entry of external air to maintain the airtight environment required for sterilization. Its sealing effect directly affects the stability and effectiveness of the sterilization process.

[0003] Current sealing structures typically use multiple hooks fixed to the pot body to hold the door in place, which is a relatively complex structure. This can lead to problems such as insufficient contact area between the hooks and the door, resulting in excessively high local pressure and potential risks when the pressure inside the sterilizer is high. Utility Model Content

[0004] The purpose of this invention is to provide a structure for sealing sterilizer doors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a structure for sealing the door of a sterilizer, including a cover body, one end of which is hinged to the top side of the pot body, a sterilization chamber is fitted inside the pot body, and a sealing mechanism is provided at the top of the sterilization chamber;

[0006] A steam pipe runs laterally through one side of the sterilization chamber and the pot body;

[0007] A waste liquid recovery mechanism is vertically inserted through the middle of the bottom of the sterilization chamber and the pot body;

[0008] A counter-pressure spray mechanism extends laterally through the other side of the sterilization chamber and the pot body, and a water storage tank extends vertically through the bottom end of the counter-pressure spray mechanism.

[0009] The beneficial effects of this utility model are as follows: the sliding groove and recess at the top of the sterilization chamber provide a stable installation base for the sealing mechanism, ensuring precise matching of components. The lead seal shielding layer under the recess enhances the sealing performance and reduces leakage. In the sealing mechanism, the drive ring is flexibly adjusted by sliding the slide bar in the sliding groove, the protrusion pushes the locking ring to lock tightly, and the elastic spring helps to quickly reset when unlocking. This not only improves the tightness and stability of the seal, but also makes the sealing and unlocking operations convenient and efficient.

[0010] To ensure a stable foundation for the installation and operation of the sealing mechanism, the groove on the outer edge of the sterilization chamber top and the groove on the inner edge of the top provide a reliable connection between the sealing components and the sealing mechanism. The lead seal shielding layer enhances the sealing performance of the sterilization chamber. Pressure and temperature sensors monitor pressure and temperature changes inside the sterilization chamber.

[0011] The sterilization chamber is further configured such that: a groove is provided on the outer edge of the top end of the sterilization chamber; a groove is provided on the inner edge of the top end of the sterilization chamber; a lead-sealed shielding layer is provided on the inner wall of the sterilization chamber directly below the groove; and a pressure sensor and a temperature sensor are respectively provided on the inner walls of both sides of the sterilization chamber.

[0012] By adopting the above technical solution, the sliding groove on the outer edge of the top of the sterilization chamber and the groove on the inner edge of the top provide a stable foundation for the installation and operation of the sealing mechanism, ensuring that the sealing components can fit precisely. The lead-sealed shielding layer on the inner wall directly below the groove can further enhance the sealing performance of the sterilization chamber and reduce the leakage of steam or other media. The pressure sensor and temperature sensor on both sides of the inner wall can monitor the pressure and temperature changes inside the sterilization chamber, making it easy to promptly determine whether the sterilization conditions meet the standards and ensuring the stability and reliability of the sterilization effect.

[0013] To allow the drive ring of the sealing mechanism to slide within the groove via a slide bar at its bottom, flexibly adjusting its position, and in conjunction with the protrusion on the inner side of the ring and the locking ring at the top of the groove, a tight lock is achieved by the protrusion pushing the locking ring. Meanwhile, the spring tension allows the locking ring to quickly return to its original position during unlocking.

[0014] The sealing mechanism is further configured such that: a drive ring is provided at the bottom end of the drive ring, the slide bar is slidably connected to the inner wall of the groove, a plurality of protrusions are provided on the inner side of the annular drive ring, a plurality of locking rings are provided on the top of the groove, and a plurality of elastic tension springs are provided between the middle section of the annular outer wall of the locking ring and the lower end of the inner wall of the groove, and the number of protrusions and locking rings is the same.

[0015] By adopting the above technical solution, the drive ring of the sealing mechanism slides in the groove through the slide bar at the bottom, realizing flexible position adjustment. With the protrusion on the inner side of the ring and the locking ring at the top of the groove, the locking ring can be tightly locked by the protrusion pushing the locking ring. The elastic spring between the locking ring and the inner wall of the groove can drive the locking ring to quickly reset when unlocking, ensuring convenient and efficient sealing and unlocking operations, improving the tightness and stability of the seal, and making the sealing state of the sterilization chamber more reliable.

[0016] To ensure that the drain pipe of the waste liquid recovery mechanism runs vertically through and connects to the recovery tank, the waste liquid generated during sterilization and spraying can be collected centrally, avoiding pollution caused by indiscriminate discharge of waste liquid:

[0017] The waste liquid recovery mechanism is further configured such that: the top end of the waste liquid recovery mechanism includes a drain pipe, the top end of which vertically penetrates the middle of the bottom of the sterilization chamber and the pot body, the bottom end of which vertically penetrates the middle of the top of the recovery tank, and the outer wall of the drain pipe is provided with a drain valve.

[0018] By adopting the above technical solution, the drain pipe of the waste liquid recovery mechanism vertically penetrates the sterilization chamber and the bottom of the pot and connects to the recovery tank. It can collect the waste liquid generated during sterilization and spraying in a concentrated manner, avoiding pollution caused by random discharge of waste liquid. The drain valve on the outer wall of the drain pipe can flexibly control the timing and speed of waste liquid discharge, which can be easily adjusted according to actual needs. This ensures the thoroughness of waste liquid recovery and avoids unnecessary impact on the internal environment of the sterilization chamber during the discharge process.

[0019] To ensure that multiple spray nozzles of the back-pressure spray mechanism are connected via water inlet pipes, allowing for even water distribution and spraying into the sterilization chamber, a water pump draws water from the storage tank via a pumping pipe, and then delivers it to the spray nozzles through the water supply pipe and inlet pipe, achieving effective spraying under back-pressure conditions.

[0020] The back pressure spraying mechanism is further configured as follows: the top ends of the spray pipes are vertically inserted into the bottom of the water inlet pipe, one end of the water inlet pipe is provided with a water delivery pipe on one side, the other end of the water delivery pipe is connected to the outlet end of a water pump, the inlet end of the water pump is connected to a water pumping pipe, the bottom end of the water pumping pipe is vertically inserted into the middle of the top of the water storage tank, and a control valve is provided on the outer wall of the water inlet pipe.

[0021] By adopting the above technical solution, multiple spray pipes of the back pressure spraying mechanism are connected through water inlet pipes, which can evenly distribute and spray water into the sterilization chamber. The water pump draws water from the water storage tank through the water pumping pipe, and delivers it to the spray pipes through the water supply pipe and water inlet pipe, providing stable power for spraying and realizing effective spraying under back pressure conditions. This helps to cool or clean the chamber after sterilization. The control valve on the outer wall of the water inlet pipe can adjust the spray flow rate, which can be flexibly adjusted according to the characteristics of the sterilized items or the post-sterilization processing requirements.

The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0039] Therefore, the "pressure sensor," "temperature sensor," and "water pump" involved in this application are physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application. The computer software programs involved in these physical functional modules are technologies known to those skilled in the art and are not improvements of this application.

[0040] The structure used for sealing sterilizer doors operates as follows:

[0041] When using it for the first time, the operator can first rotate the drive ring 401 of the sealing mechanism 4 so that the slide bar 402 at the bottom can rotate and slide in the slide groove 301 at the top of the sterilization chamber 3. During this time, the protrusion 403 of the drive ring 401 will move and gradually approach the locking ring 404. When the protrusion 403 rotates and contacts the outer wall of the locking ring 404, it will push it, so that several locking rings 404 move towards the inside of the opening of the sterilization chamber 3, thereby splicing them into a ring structure that is close to a complete circle. At this time, the elastic spring 405 is in the pulled state. Then, the operator can put the items to be sterilized into the sterilization chamber 3 and close the cover 1, so that the bottom edge of the cover 1 presses tightly against the top of the ring structure spliced ​​by several locking rings 404, and the bottom outer wall of the cover 1 will be tightly attached to the lead seal shielding layer 303 on the inner wall of the sterilization chamber 3 to complete the seal.

[0042] After sealing, the operator can introduce steam into the sterilization chamber 3 through the steam pipe 5 that runs horizontally through one side of the sterilization chamber 3 and the pot body 2 for sterilization. During the process, the pressure sensor 304 (model: S-10) and temperature sensor 305 (model: Omega HSRTD) on both sides of the inner wall of the sterilization chamber 3 monitor the internal pressure and temperature respectively. After sterilization, the operator can start the water pump 704 (model: DBW3-25) of the back pressure spray mechanism 7 through the external controller (model: S7-1200), so that it draws water from the water storage tank 8 through the plugged-in water pipe 705. During this period, the water will enter the water inlet pipe 702 through the water supply pipe 703, and then be evenly distributed in several vertically penetrating spray pipes 701 at the bottom through the water inlet pipe 702, and spray back pressure into the sterilization chamber 3 from the nozzles of the spray pipes 701. During this period, the control valve 706 on the outer wall of the water inlet pipe 702 can adjust the spray flow rate.

[0043] The waste liquid generated by the spraying will collect at the bottom of the sterilization chamber 3 under the action of gravity. At this time, the operator can open the drain valve 603 of the waste liquid recovery mechanism 6, so that the waste liquid flows into the recovery tank 602 through the drain pipe 601 that runs vertically through the bottom middle of the sterilization chamber 3 and the pot body 2, thus completing the waste liquid discharge.

[0044] After the waste liquid is discharged and recycled, the operator can open the cover 1 and rotate the drive ring 401 in the opposite direction, thereby causing the protrusion 403 to disengage from the locking ring 404. At the same time, after the locking ring 404 is released from the pushing restriction, several elastic springs 405 located between the locking ring 404 and the inner wall of the groove 302 will retract to their original positions and pull the connected locking ring 404 to reset. Then the sterilized items can be taken out.
