Description

Technical Field

[0001] This utility model relates to the field of medical cleanroom tool technology, specifically a differential pressure sensor with a transfer window. Background Technology

[0002] A pass-through window (also known as a pass-through partition or pass-through device) is a facility used to transfer items between two different areas. It is typically used in specialized environments such as laboratories, pharmaceutical plants, and hospitals. Currently, medical pass-through windows usually have differential pressure sensors installed inside to ensure there are no leaks. Since air circulation is required inside the pass-through window, a fan is installed to ensure proper airflow. When the air pressure inside the pass-through window exceeds the pressure the differential pressure sensor can withstand, it can easily be damaged. Because differential pressure sensors are usually installed using tools for secure fastening, damaged sensors need to be replaced promptly. If the appropriate tools cannot be quickly used to disassemble the differential pressure sensor on-site, the disassembly process is slow, creating a gap in differential pressure monitoring and affecting the monitoring of the pass-through window's differential pressure, thus reducing the effectiveness of the differential pressure sensor.

[0003] Therefore, it is necessary to develop a differential pressure sensor with a transfer window. Utility Model Content

[0004] The purpose of this invention is to provide a differential pressure sensor with a transmission window to solve the problems mentioned in the background art.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By sliding the sleeve of the differential pressure sensor with sealing ring A into the mounting hole on the transfer window and locking the bushing, and before installing the mounting head on the knob below the outer wall of the differential pressure sensor, sealing ring B is first inserted.

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.

[0022] This utility model provides the following technical solution: a differential pressure sensor with a transmission window, please refer to... Figures 1-4 The system includes a pass-through window 1, with a mounting hole 101 at the center of the upper part of the pass-through window 1. A display screen 102 is mounted on one side of the upper front face of the pass-through window 1, and a ventilation plate 103 is mounted on one side of the lower front face of the pass-through window 1. A high-efficiency filter 2 is mounted on the upper part of the pass-through window 1. Connecting pipes 201 are provided on both sides of the bottom of the high-efficiency filter 2, and nozzles 202 are installed at the bottom end of the connecting pipes 201. A fan 3 is mounted on one side of the lower part of the pass-through window 1. An air inlet pipe 301 is installed on the air inlet end of the fan 3, and an air outlet pipe 302 is installed on the air outlet end of the fan 3. One end of the air outlet pipe 302 is fixedly connected to the center of the top of the high-efficiency filter 2. The main structure of the pass-through window 1 in the prior art is that of a fan 3 and a high-efficiency filter 2 installed inside the pass-through window 1. The fan 3 is one of the core components of the transfer window 1. Its working principle is to draw in indoor air through the air inlet pipe 301 on the fan 3, and then deliver it to the high-efficiency filter 2 through the air outlet pipe 302. The filtered air returns to the room, forming an air circulation effect. During operation, the speed of the fan 3 is closely related to the air flow. A well-designed fan 3 can not only effectively reduce energy consumption, but also improve the stability and comfort of air delivery. The high-efficiency filter 2 is responsible for removing pollutants in the air, such as dust, pollen, bacteria and viruses. This type of filter usually uses multiple layers of filter media. Its working principle is to capture tiny particles in the air through physical and electrostatic effects. When air flows through the high-efficiency filter 2, the particles are captured in the filter media, ensuring that the air entering the room is clean and safe.

[0023] A differential pressure sensor 4 is installed inside the mounting hole 101. A sleeve 401 is installed on the upper part of the outer wall of the differential pressure sensor 4. The outer wall of the sleeve 401 is slidably connected to the inner wall of the mounting hole 101. A sealing ring A402 is slidably connected to the upper part of the outer wall of the sleeve 401. A locking bushing 403 is installed on the lower part of the outer wall of the sleeve 401. The inner wall of the locking bushing 403 is threadedly connected to the lower part of the outer wall of the sleeve 401. A knob 404 is slidably connected to the center of the bottom of the locking bushing 403. An installation head 405 is installed on the top of the knob 404. The inner wall of the installation head 405 is threadedly connected to the lower part of the outer wall of the differential pressure sensor 4. A sealing ring B406 is provided on the top of the installation head 405. The inner wall of the sealing ring B406 is slidably connected to the lower part of the outer wall of the differential pressure sensor 4. The sleeve 401 on the device 4 is slidably installed in the mounting hole 101 on the transfer window 1 with the sealing ring A402, and the locking bushing 403 is locked. Before the mounting head 405 on the knob 404 is installed below the outer wall of the differential pressure sensor 4, the sealing ring B406 is first inserted so that the differential pressure sensor 4 can monitor the internal differential pressure of the transfer window 1 after installation. During the installation of the differential pressure sensor 4, no tools are required for installation. This avoids the situation where the differential pressure sensor 4 needs to be disassembled with tools after damage, which would affect the disassembly efficiency. It also avoids the situation where the slow disassembly efficiency would affect the monitoring of the internal differential pressure of the transfer window 1. This reduces the gap between the installation and disassembly of the differential pressure sensor and ensures that the differential pressure sensor 4 can monitor the differential pressure of the transfer window 1 in a timely manner.

[0024] Working Principle: In using this utility model, a fan 3 and a high-efficiency filter 2 are installed inside the pass-through window 1, which is the main structure of the pass-through window 1 in the prior art. The fan 3 is one of the core components of the pass-through window 1. Its working principle is that indoor air is drawn in through the air inlet pipe 301 on the fan 3, and then transported to the high-efficiency filter 2 through the air outlet pipe 302. The filtered air returns to the room, forming an air circulation effect. During operation, the speed of the fan 3 is closely related to the air flow. A well-designed fan 3 can not only effectively reduce energy consumption, but also improve the stability and comfort of air delivery. The high-efficiency filter 2 is responsible for removing pollutants in the air, such as dust, pollen, bacteria, and viruses. This type of filter usually uses multi-layer filter media. Its working principle is to capture tiny particles in the air through physical and electrostatic effects. When air flows through the high-efficiency filter 2, the particles are captured in the filter. In order to ensure that the air entering the room is clean and safe, the sleeve 401 on the differential pressure sensor 4 is slidably installed in the mounting hole 101 on the transfer window 1 with the sealing ring A402, and the locking bushing 403 is locked. Before the mounting head 405 on the knob 404 is installed below the outer wall of the differential pressure sensor 4, the sealing ring B406 is first inserted. After the differential pressure sensor 4 is installed, differential pressure monitoring can be performed on the inside of the transfer window 1. During the installation of the differential pressure sensor 4, no tools are required for installation. This avoids the situation where the differential pressure sensor 4 needs to be disassembled with tools after damage, which would affect the disassembly efficiency. It also avoids the situation where the slow disassembly efficiency would affect the differential pressure monitoring inside the transfer window 1. This reduces the interval between the installation and disassembly of the differential pressure sensor, ensures that the differential pressure sensor 4 can monitor the differential pressure of the transfer window 1 in a timely manner, and effectively improves the performance of the differential pressure sensor in the transfer window.
