Description

Technical Field

[0001] This utility model relates to the field of cleanroom technology, and in particular to a device for easy disassembly and assembly of a pressure gauge and a pulsating vacuum sterilizer containing the same. Background Technology

[0002] In modern pharmaceutical, biotechnology, microelectronics, and certain precision manufacturing industries, cleanrooms are crucial facilities for ensuring product quality and a sterile, dust-free production environment. The interior of a cleanroom is typically divided into different cleanliness levels, such as the internationally recognized Class A, B, C, and D cleanrooms, with partitions separating these different cleanroom areas for physical separation.

[0003] Typically, cross-zone pulsed vacuum sterilizers are installed between different clean zones (e.g., between Class B and Class C). These sterilizers can sterilize items (such as tools, components, sterile gowns, and some packaging materials) entering from lower-cleanliness-level clean zones to higher-cleanliness-level clean zones. Generally, pulsed vacuum sterilizers are installed by embedding them into the partition wall between two adjacent clean zones, with sealant applied at the contact point. To minimize interference from airflow patterns and pressure differential balance within the higher-cleanliness-level clean zone and to optimize space utilization, the side surface of the pulsed vacuum sterilizer chamber located on the higher-cleanliness-level clean zone side is usually flush with the partition wall surface.

[0004] The pulsating vacuum sterilizer is equipped with multiple pressure gauges (such as jacket pressure gauges and inner chamber pressure gauges) at both ends facing different clean rooms to monitor its working status. In accordance with relevant regulations and quality management standards, the pressure gauges installed on it need to be calibrated and replaced every six months.

[0005] However, in the existing technology, there are at least the following significant drawbacks when disassembling and assembling a pressure gauge to replace it:

[0006] 1. The traditional method of installing pressure gauges on pulsed vacuum sterilizers is to use bolts for installation, which makes the installation and removal of pressure gauges extremely inconvenient, thus reducing the efficiency of installation and removal and increasing labor costs.

[0007] 2. Because the side surface of the pulsed vacuum sterilizer chamber, located on the side of a higher-cleanliness-level clean area, is flush with the partition wall, the operation of removing or installing pressure gauges at the partition wall location (i.e., the cross-zone location) often requires the operator to work together in the clean areas on both sides of the partition wall. This means that after removing the bolts securing the pressure gauge in the lower-cleanliness-level clean area, the operator needs to change into higher-cleanliness-level protective clothing and enter the higher-cleanliness-level clean area to retrieve the pressure gauge. This not only makes the removal and installation of pressure gauges extremely inconvenient, reduces efficiency, and increases labor costs, but also increases the risk of contamination in the higher-cleanliness-level clean area.

[0008] 3. Traditionally, pressure gauges on pulsed vacuum sterilizers are installed in pre-drilled pressure gauge holes. Therefore, when the pressure gauge at the partition wall location (i.e., the cross-zone location) is removed or installed, the cleanrooms on either side of the partition wall will exchange air through the pressure gauge holes due to the pressure difference between them, thus increasing energy consumption in higher cleanroom areas.

[0009] Therefore, how to improve the convenience of disassembly and assembly work, thereby increasing disassembly and assembly efficiency, reducing labor costs, and at the same time reducing the risk of contamination to clean areas with higher cleanliness levels, and avoiding unnecessary energy consumption in clean areas with higher cleanliness levels, has become an urgent problem to be solved. Utility Model Content

[0011] To achieve the above objectives, this utility model provides the following solution:

[0012] In a first aspect, this utility model provides a device for easily assembling and disassembling a pressure gauge, comprising two mounting brackets respectively installed on the inner sidewalls opposite to each other of the top flange at the top of the pulsating vacuum sterilizer body, wherein:

[0021] When the fixing plate is detachably installed on the top of the central web plate, the bottom end of the fixing block and the bottom end of the inner wall of the gauge body mounting groove form a cylindrical structure with the same cross-sectional area as the gauge body, so as to fix the pressure gauge installed on the mounting bracket.

[0022] According to one embodiment of the present utility model, a first buffer anti-slip layer with the same arc structure as the bottom end of the fixing block is installed at the bottom end, and a second buffer anti-slip layer with the same arc structure as the bottom end of the inner wall of the watch body mounting groove is installed at the bottom end of the inner wall.

[0023] The thickness of both the first and second buffer anti-slip layers is 0.1mm-0.3mm.

[0024] According to one embodiment of the present invention, a locking mechanism is installed on the mounting bracket, the locking mechanism being configured to detachably mount the fixing plate to the top of the central web plate, wherein:

[0025] The locking mechanism includes at least a locking rod that is slidably mounted on the mounting bracket. The top of the fixing plate is provided with a locking groove, which is adapted to and correspondingly set with the locking rod. One end of the locking rod near the fixing plate is configured to extend into the locking groove so that the fixing plate can be detachably mounted on the top of the central web plate.

[0034] Beneficial effects

[0035] This utility model has at least the following technical effects:

[0036] 1. With the installation of the mounting bracket, the gauge body mounting groove, the first viewing hole and the second viewing hole, the pressure gauge can be directly installed in the gauge body mounting groove opened on the mounting bracket, thus eliminating the need to use bolts to install the pressure gauge, thereby improving the convenience of disassembly and assembly, increasing disassembly and assembly efficiency, and reducing labor costs.

[0037] 2. By designing a mounting bracket, a mounting slot for the gauge body, a first viewing hole, and a second viewing hole, this utility model allows operators to disassemble or install pressure gauges located in a higher cleanliness level clean area without having to enter the higher cleanliness level clean area.

[0060] In the following embodiments, there may be descriptions such as "this device". Those skilled in the art should understand that "this device" refers to a device provided by the present invention that facilitates the assembly and disassembly of a pressure gauge.

[0061] pressure gauge

[0062] like Figure 12 and Figure 13 As shown, Figure 12 and Figure 13 The diagrams provided are exemplary schematic representations of the overall structure of pressure gauges in the prior art. The pressure gauges can be jacketed pressure gauges or internal chamber pressure gauges known in the art, and will not be described in detail here.

[0063] like Figure 12 As shown, the pressure gauge generally consists of a cylindrical dial 22, an outer edge 23 of the dial, and a cylindrical body 24. The dial 22 is located... Figure 12 On the right side of the dial, a reading and pointer (not shown in the figure) are installed to display the working status of the pulsed vacuum sterilizer body 1. The outer edge 23 of the dial is a circular structure, with its inner ring fitting onto the outer wall of the cylindrical dial 22. The dial body 24 is located on... Figure 12 On the left side, it is connected to and coaxially arranged with the dial 22. The cross-sectional area of ​​the dial body 24 (i.e., the section perpendicular to its axis) is smaller than the cross-sectional area of ​​the outer ring of the dial outer edge 23 (i.e., the section perpendicular to its axis). The above are all prior art known in the art, and will not be elaborated further here.

[0064] like Figure 13 As shown, a wire mounting block (not shown in the figure) for placing wires is installed at the end of the gauge body 24 away from the outer edge 23 of the dial. The wire mounting block is also a cylindrical structure with external threads on its outer wall, so it can be threaded into external parts with internal threads. It should be understood that the pressure gauge wires can be communicatively (or electrically) connected to the pulsating vacuum sterilizer body 1 to monitor the operating status of the pulsating vacuum sterilizer body 1. The above content is all prior art known in the art and will not be described in detail here.

[0065] Pulsating vacuum sterilizer

[0066] like Figure 6 As shown, the pulsed vacuum sterilizer in this embodiment is... Figure 6 The pulsed vacuum sterilizer body 1 is capable of sterilizing items (including but not limited to tools, components, sterile gowns, and some packaging materials) that enter a higher cleanliness level clean area from a lower cleanliness level clean area. The pulsed vacuum sterilizer body 1 is embedded within the partition wall between two adjacent clean areas, and the side surface of the pulsed vacuum sterilizer body 1 located in the higher cleanliness level clean area is flush with the partition wall. A top flange 2, which is a sheet metal structure, is installed circumferentially at the top of the pulsed vacuum sterilizer body 1. The above descriptions are all prior art known in the art and will not be elaborated further.

[0067] Example

[0068] Firstly, such as Figures 1-11 As shown, this utility model provides a device for easy assembly and disassembly of a pressure gauge. The device includes at least two mounting brackets 3 respectively installed on the inner sidewalls opposite to each other of the top flange 2 at the top of the pulsating vacuum sterilizer body 1, wherein:

[0069] like Figure 7 and Figure 8 As shown, the mounting bracket 3 is a U-shaped structure with a central web 301 and two flanges 302. Figure 1 , Figure 2 and Figure 5 As shown, the flange plate 302 is mounted on the inner wall of the top flange 2.

[0070] It should be understood that the middle part of the mounting frame 3 of the U-shaped structure is the central web plate 301, and the two parts at both ends that are connected to the central web plate 301 and perpendicular to each other are the two flange plates 302.

[0071] like Figure 1 , Figure 5 , Figure 7 and Figure 8 As shown, along its length direction (i.e. along) the central web 301 Figure 8 At least two gauge mounting slots 5 are provided in the transverse direction of the central web 301, which can be used to install the gauge body 24 of the pressure gauge. The gauge mounting slots 5 are located at the top of the central web 301, that is, the top of the gauge mounting slots 5 are connected to the outside of the central web 301.

[0072] In this embodiment, the preferred number of mounting slots 5 on the watch body is... Figure 8 The two gauge mounting slots 5 shown are preferably symmetrically arranged with the center line of the central web 301 as the axis of symmetry. The two gauge mounting slots 5 can respectively install the gauge body 24 of the jacket pressure gauge and the gauge body 24 of the inner chamber pressure gauge, thereby enabling the monitoring of different working states of the pulsating vacuum sterilizer body 1 using two different pressure gauges.

[0073] like Figure 7 and Figure 8 As shown, a partition 4 parallel to the central web plate 301 is installed between the two flange plates 302. A gap with the same width as the outer edge 23 of the pressure gauge dial is provided between the partition 4 and the central web plate 301. That is, a gap for placing the outer edge 23 of the pressure gauge dial is provided between the partition 4 and the central web plate 301, and the width of this gap is the same as the width of the outer edge 23 of the pressure gauge dial.

[0074] In this embodiment, the top and bottom ends of the partition 4 are preferably flush with the top and bottom ends of the flange 302. The width of the gap between the partition 4 and the central web 301 can also be slightly smaller than the width of the outer edge 23 of the pressure gauge dial, by as little as 0.01 mm. That is, when the outer edge 23 of the pressure gauge dial is located within the gap between the partition 4 and the central web 301, the inner wall of the gap between the partition 4 and the central web 301 will have a slight interference fit with the outer wall of the pressure gauge dial outer edge 23, with the interference amount being the aforementioned 0.01 mm.

[0075] In this embodiment, as Figure 8 As shown, the partition 4 is also provided at a certain distance from the end of the flange 302 away from the central web 301. That is, the partition 4 is installed between the end of the flange 302 away from the central web 301 and the central web 301, rather than at the end of the flange 302 away from the central web 301.

[0076] In this embodiment, the connection between the partition 4 and the flange 302 can be a detachable connection by bolts or a fixed connection by welding, and no particular limitation is made here.

[0077] like Figure 7 and Figure 8 As shown, at least two first viewing holes 6 are provided on the partition plate 4, which are the same as the shape and cross-sectional area (i.e. the cross section perpendicular to its axis) of the dial 22 of the pressure gauge. The two first viewing holes 6 are respectively provided with two gauge body mounting slots 5, and the two first viewing holes 6 are both cylindrical structures.

[0078] In this embodiment, since there are two watch body mounting slots 5, and the first viewing hole 6 is correspondingly provided with the watch body mounting slot 5, there are also two first viewing holes 6.

[0079] When the pressure gauge body 24 is installed in the gauge body mounting slot 5, that is, when the outer edge 23 of the pressure gauge dial is located in the gap between the partition plate 4 and the central web plate 301 (i.e., when the pressure gauge is installed on the mounting bracket 3), the first viewing hole 6 will be exactly coaxial with the pressure gauge dial 22. Since the shape and cross-sectional area of ​​the pressure gauge dial 22 are the same as those of the first viewing hole 6, the first viewing hole 6 will not block the information inside the pressure gauge dial 22 (i.e., its internal readings and pointers, etc.). In other words, when the pressure gauge is installed on the mounting bracket 3, the inner wall of the first viewing hole 6 will be exactly flush with the inner ring of the outer edge 23 of the pressure gauge dial.

[0080] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, at least two second viewing holes 12 are provided at each of the opposite ends of the top flange 2, preferably two second viewing holes 12 are provided at each of the opposite ends of the top flange 2. The two second viewing holes 12 are respectively coaxially arranged with the two first viewing holes 6 located on the same side. The shape of the second viewing hole 12 is the same as the shape of the first viewing hole 6 (i.e., both are cylindrical structures), and its cross-sectional area (i.e., the section perpendicular to its axial direction) is greater than the cross-sectional area of ​​the first viewing hole 6.

[0081] In this embodiment, since the shape of the second viewing hole 12 is the same as that of the first viewing hole 6 and its cross-sectional area is larger than that of the first viewing hole 6, the second viewing hole 12 will not block the information inside the dial 22 of the pressure gauge when the pressure gauge is installed on the mounting bracket 3.

[0082] like Figure 1 , Figure 4 and Figure 5 As shown, a transparent layer 13 that can completely cover the second viewing hole 12 is installed on the outer wall of the top flange 2. A sealing layer (not shown in the figure) is provided at the connection between the transparent layer 13 and the outer wall of the top flange 2.

[0083] In this embodiment, the transparent layer 13 can be made of colorless transparent glass or colorless transparent acrylic material known in the art, and is not particularly limited herein. Taking the transparent layer 13 made of colorless transparent glass as an example, it can be bonded to the outer wall of the top flange 2 using glass adhesive known in the art, and the glass adhesive can be the aforementioned sealing layer.

[0084] When installing or removing pressure gauges, especially those located in a higher-cleanliness-level clean area, operators can perform the work only within the lower-cleanliness-level clean area. This eliminates the need for operators to enter the higher-cleanliness-level clean area, thus improving convenience, efficiency, and reducing labor costs. Furthermore, since operators do not need to enter the higher-cleanliness-level clean area, the risk of contamination of that area is reduced.

[0085] Meanwhile, in one embodiment of this utility model, the pressure gauge is installed on the mounting bracket 3, which does not need to be installed in the pressure gauge hole pre-opened on the traditional pulse vacuum sterilizer, and the second viewing hole 12 is covered with a transparent layer 13. Therefore, the clean rooms located on both sides of the partition wall will not exchange air, thereby avoiding unnecessary energy consumption in the clean area with a higher cleanliness level.

[0086] Furthermore, such as Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the bottom of the inner wall of the gauge mounting groove 5 is an arc-shaped structure that is adapted to the gauge body 24 of the pressure gauge, and the arc-shaped structures at the bottom of the inner walls of the two gauge mounting grooves 5 are coaxial with and correspondingly set with the two first viewing holes 6.

[0087] In this embodiment, the cross-section (i.e. the section perpendicular to its axis) of the arc-shaped structure at the bottom of the inner wall of the watch mounting groove 5 can be a semi-circular structure.

[0088] Furthermore, the diameter of the gauge mounting groove 5 can be slightly smaller than the diameter of the gauge body 24, by as little as 0.01 mm. That is, when the gauge body 24 is installed in the gauge mounting groove 5, the inner wall of the gauge mounting groove 5 will be in a state of slight interference fit with the outer wall of the gauge body 24, and the interference amount is the aforementioned 0.01 mm.

[0089] Furthermore, such as Figures 1-3 , Figure 5 , Figure 9 and Figure 10 As shown, a fixing plate 9 is detachably installed at the top of the central web plate 301. At least two fixing blocks 7 are installed at the bottom of the fixing plate 9, preferably two fixing blocks 7. The two fixing blocks 7 are arranged one-to-one with the two gauge body mounting slots 5. The fixing blocks 7 are configured to be able to extend into the gauge body mounting slots 5, and the bottom of the fixing blocks 7 is an arc-shaped structure adapted to the gauge body 24 of the pressure gauge.

[0090] In this embodiment, as Figure 9 and Figure 10 As shown, the fixing plate 9 can be a flat cuboid structure, and the fixing block 7 can be a cuboid structure.

[0091] In this embodiment, the width of the fixing block 7 can be the same as the width of the gauge body mounting groove 5. The cross-section (i.e., the section perpendicular to its axial direction) of the arc-shaped structure at the bottom of the fixing block 7 can be a semi-circular structure. That is, when the fixing plate 9 is detachably installed at the top of the central web plate 301, the bottom end of the fixing block 7 and the bottom end of the inner wall of the gauge body mounting groove 5 will form a cylindrical structure with the same cross-sectional area as the gauge body 24, thereby fixing the pressure gauge installed on the mounting bracket 3 (i.e., fixing the gauge body 24 of the pressure gauge installed in the gauge body mounting groove 5).

[0092] By using the fixing block 7 and the fixing plate 9, the pressure gauge installed on the mounting bracket 3 can be more securely fixed.

[0093] Furthermore, such as Figure 3 As shown, a first buffer anti-slip layer 8 with the same arc-shaped structure as the bottom of the fixing block 7 is installed at the bottom end, and a second buffer anti-slip layer 11 with the same arc-shaped structure as the bottom of the inner wall of the watch body mounting groove 5 is installed at the bottom end of the inner wall. The thickness of both the first buffer anti-slip layer 8 and the second buffer anti-slip layer 11 is 0.1mm-0.3mm, preferably 0.1mm.

[0094] In this embodiment, both the first buffer anti-slip layer 8 and the second buffer anti-slip layer 11 can be made of elastic silicone material, and no particular limitation is made here.

[0095] By setting the first buffer anti-slip layer 8 and the second buffer anti-slip layer 11, the friction between the pressure gauge body 24 and the bottom end of the fixing block 7, and between the pressure gauge body 24 and the bottom end of the inner wall of the gauge body mounting groove 5, can be increased, which can further improve the firmness of the pressure gauge installation. At the same time, the first buffer anti-slip layer 8 and the second buffer anti-slip layer 11 can also prevent the pressure gauge from rotating in its own circumferential direction during subsequent operation, thereby ensuring that the reading in the pressure gauge dial 22 is always in an easily readable position, improving the working efficiency of monitoring the pulse vacuum sterilizer body 1.

[0096] Specifically, such as Figure 2 and Figure 11 As shown, a locking mechanism is installed on the mounting bracket 3. The locking mechanism is configured to allow the fixing plate 9 to be detachably installed on the top of the central web plate 301, wherein:

[0097] The locking mechanism includes at least a locking rod 16 that is slidably mounted on the mounting bracket 3, and the locking rod 16 is preferably slidably mounted on the mounting bracket 3 in a horizontal direction. Figure 9 As shown, a locking groove 10 is provided at the top of the fixing plate 9. The locking groove 10 is adapted to and correspondingly set with the locking rod 16. The end of the locking rod 16 near the fixing plate 9 is configured to be able to extend into the locking groove 10, so that the fixing plate 9 can be detachably installed at the top of the central web plate 301.

[0098] In this embodiment, as Figure 1 and Figure 5 As shown, the locking mechanism is preferably two, and is sequentially arranged at both ends of the mounting bracket 3. Since there are two locking mechanisms, therefore, as... Figure 9 As shown, there are two locking slots 10, and the two locking slots 10 are sequentially opened at both ends of the fixed plate 9 and are respectively set to correspond to the locking rods 16 in the two locking mechanisms.

[0099] In this embodiment, as Figure 2 , Figure 9 and Figure 11 As shown, the locking rod 16 can be a long rectangular parallelepiped structure, and the locking groove 10 can be a rectangular parallelepiped structure.

[0100] More specifically, the locking mechanism also includes a second limiting block 19 mounted on the mounting bracket 3, and a locking rod 16 passing through the second limiting block 19 and engaging with the second limiting block 19 in a limiting sliding cooperation, that is, the locking rod 16 is limited and slidably connected to the mounting bracket 3 through the second limiting block 19.

[0101] In this embodiment, as Figure 2As shown, the second limiting block 19 can be installed on the top of the mounting bracket 3, that is, on the top of the flange plate 302. The second limiting block 19 can be connected to the top of the flange plate 302 by bolts.

[0102] In this embodiment, the second limiting block 19 may have a locking rod sliding hole in the horizontal direction. The locking rod 16 is located in the locking rod sliding hole and slides in cooperation with the inner wall of the locking rod sliding hole. That is, the locking rod 16 passes through the second limiting block 19 and slides in cooperation with the second limiting block 19.

[0103] Furthermore, such as Figure 2 and Figure 11 As shown, a first limiting block 17 is installed on the locking rod 16. The first limiting block 17 is located between the end of the locking rod 16 away from the second limiting block 19 and the second limiting block 19, meaning there is a certain distance between the first limiting block 17 and the second limiting block 19, and between the first limiting block 17 and the end of the locking rod 16 away from the second limiting block 19. A spring 18 is sleeved on the locking rod 16, and both ends of the spring 18 are connected to the first limiting block 17 and the second limiting block 19, respectively. A pull ring 20 is installed on the end of the locking rod 16 away from the locking groove 10.

[0104] By using the spring 18, the locking rod 16 can be kept inside the locking groove 10 by the elastic force of the spring 18, thereby ensuring the continuous connection between the fixing plate 9 and the top of the central web plate 301, which in turn ensures the continuous firmness of the pressure gauge installed on the mounting bracket 3.

[0105] By using the pull ring 20, when it is necessary to disengage the locking lever 16 from the locking groove 10, i.e., when it is necessary to remove the pressure gauge from the mounting bracket 3, the locking lever 16 can be pulled more easily (i.e., pulled towards the locking groove 10). Figure 2 Pull the locking lever 16 on the left side.

[0106] Specifically, such as Figure 2 As shown, a second mounting block 15 is fixedly installed on the inner wall of the top flange 2, and a first mounting block 14 is fixedly installed on the flange 302 (i.e., on the outer wall of the flange 302). The first mounting block 14 is configured to be bolted to the second mounting block 15, thereby mounting the mounting bracket 3 on the inner wall of the top flange 2.

[0107] In this embodiment, the second mounting block 15 and the top flange 2, and the first mounting block 14 and the outer wall of the flange plate 302 can be fixedly connected by welding.

[0108] In this embodiment, as Figure 1 , Figure 2 and Figure 5As shown, there can be two first mounting blocks 14, which are sequentially fixedly installed on the two opposite outer side walls of the two flange plates 302. Since the first mounting blocks 14 are designed to be bolted to the second mounting blocks 15, there are also two second mounting blocks 15, which are sequentially set to correspond one-to-one with the two first mounting blocks 14.

[0109] In this embodiment, as Figure 2 As shown, the first mounting block 14 can be a cuboid structure, and the second mounting block 15 can also be a cuboid structure. The top of the second mounting block 15 can have a cuboid mounting groove for the first mounting block, and the first mounting block 14 can be installed within this groove. Wherein, as... Figure 2 As shown, the number of bolts connecting the first mounting block 14 and the second mounting block 15 can be one, and it can be arranged in a vertical direction, without any special limitation.

[0110] Furthermore, a spring washer (not shown in the figure), known in the art, can be provided between the bolt head of the bolt between the first mounting block 14 and the second mounting block 15 and the top of the first mounting block 14, thereby effectively preventing the bolt from loosening.

[0111] Furthermore, such as Figure 2 As shown, a lighting lamp 21 is installed on the mounting bracket 3. The lighting lamp 21 can preferably be an LED lamp known in the art. The lighting end of the lighting lamp 21 is set to correspond to the dial 22 of the pressure gauge.

[0112] In this embodiment, the mounting end of the lighting lamp 21 (i.e. Figure 2 The left end of the central lighting lamp 21 can be bolted to the top of the flange plate 302, and the lighting end of the lighting lamp 21 is the... Figure 2 The right end of the central lighting lamp 21. The lighting lamp 21 can be connected to an external power supply device via a wire (not shown in the figure), which is prior art known in the art and will not be described in detail here.

[0113] In this embodiment, as Figure 2 As shown, the illumination end of the lamp 21 can be located at the distance between the partition 4 and the end of the flange 302 away from the central web 301, that is, the illumination end of the lamp 21 is set to correspond to the dial 22 of the pressure gauge.

[0114] By setting up the lighting lamp 21, the dial 22 of the pressure gauge can be illuminated, thereby improving the readability of the dial 22 of the pressure gauge and improving the working efficiency of the monitoring pulse vacuum sterilizer body 1.

[0115] Furthermore, a spring washer (not shown in the figure), known in the art, can also be provided between the bolt head of the bolt between the lighting lamp 21 and the flange plate 302 and the top of the flange plate 302, thereby effectively preventing the bolt from loosening.

[0116] Secondly, this utility model provides a pulsating vacuum sterilizer, which includes the device described above for easy disassembly and assembly of the pressure gauge. It should be understood that any pulsating vacuum sterilizer including this device should be included within the protection scope of this utility model.

[0117] Those skilled in the art should understand that the above embodiments or implementation schemes of this utility model can be combined with each other and have corresponding technical effects.

[0118] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
