Description

Technical Field

[0001] This utility model relates to the field of pressure sensor technology, and more specifically to a sanitary pressure sensor. Background Technology

[0002] In critical industries such as food, pharmaceuticals, and biomedicine, extremely high hygiene standards are required for the production environment. For example, in food processing, from the initial processing of raw materials to final packaging, the entire workshop environment must be kept highly clean to prevent the growth of microorganisms and contamination by foreign objects.

[0003] Existing sensors may rust or corrode during food and pharmaceutical production due to contact with acidic, alkaline, or corrosive chemicals. This could lead to decreased sensor performance, increased measurement errors, or even the release of metal ions that contaminate products, threatening food safety or pharmaceutical purity. Furthermore, the sensors may be unsuitable for pressure detection in different media (such as acidic, alkaline, and high-temperature environments), requiring replacement of the entire sensor or frequent calibration. This also makes subsequent cleaning of the sensor's internal components inconvenient, increasing equipment and time costs. Utility Model Content

[0005] This utility model provides the following technical solution: a sanitary pressure sensor, including a bottom assembly, an installation assembly on the top of the bottom assembly, and disassembly assemblies symmetrically arranged on both sides of the bottom assembly. A fixing assembly is installed inside the installation assembly, and a detection assembly is installed inside the bottom assembly and the installation assembly. The detection assembly includes a sensor body, a collar, and an isolation diaphragm. The sensor body is disposed inside the housing, the collar is movably engaged inside the housing, and the isolation diaphragm is made of stainless steel and is fixedly sleeved inside the collar. The surface of the isolation diaphragm is polished to Ra≤0.8μm.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The sanitary pressure sensor involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Reference Figure 1-6 This utility model provides a sanitary pressure sensor, including a bottom component 1, an installation component 2 on the top of the bottom component 1, disassembly components 3 symmetrically arranged on both sides of the bottom component 1, a fixing component 4 installed inside the installation component 2, and a detection component 5 installed inside the bottom component 1 and the installation component 2.

[0025] The bottom assembly 1 includes a housing 101, a flange 102, a sealing ring 103, and a snap-fit ​​groove 104. The housing 101 has symmetrical slots on both sides of its top. The flange 102 is fixedly installed on the bottom of the housing 101. The sealing ring 103 is movably snapped onto the inner wall of the housing 101. The snap-fit ​​groove 104 is symmetrically opened on the left and right sides of the inner wall of the housing 101, which helps to improve the sealing of the sensor through the sealing ring 103 and ensure the accuracy of the detection.

[0026] Mounting assembly 2 includes a housing 201, limiting blocks 202, fixing grooves 203, fixing blocks 204, and springs 205. Limiting blocks 202 are symmetrically arranged on both sides of the housing 201. The housing 201 is slidably engaged with the grooves on both sides of the top of the housing 101 via the limiting blocks 202, and the bottom of the housing 201 is tightly fitted against the sealing ring 103. The fixing grooves 203 are evenly formed on the inner wall of the housing 201. One side of the fixing block 204 is inclined, and the fixing blocks 204 are symmetrically fitted inside the two sides of the housing 201. Specifically... The mounting assembly 2 is configured as a movable sleeve, and the fixing block 204 is movably engaged inside the locking groove 104. The spring 205 is located inside both sides of the housing 201, on one side of the fixing block 204. This facilitates the sliding of the fixing blocks 204 into the locking groove 104 when the housing 201 and the limiting block 202 are respectively inserted into the slots on both sides of the top of the housing 101. The limiting block 202 and the fixing block 204 fix the housing 201 inside the housing 101, so that the sensor of the mounting assembly 2 will not shake during operation.

[0027] The disassembly assembly 3 includes an anti-contact shell 301, a sliding rod 302, a limiting plate 303, and a pushing ball 304. The anti-contact shell 301 is symmetrically arranged on the outside of both sides of the housing 101. The sliding rod 302 is movably sleeved inside both sides of the housing 101, and the limiting plate 303 is provided on the right side of the sliding rod 302. One side of the pushing ball 304 is fixedly installed on the left side of the sliding rod 302, located on the right side of the fixing block 204. This allows the operator to press the limiting plate 303 into the inside of the housing 101. The limiting plate 303, the sliding rod 302, and the pushing ball 304 move towards the fixing block 204, pressing the fixing block 204 into the inside of the housing 201. The fixing block 204 compresses the spring 205. After the fixing block 204 enters the inside of the housing 201, the mounting assembly 2 can be removed upwards. At the same time, when the sensor is running, the anti-contact shells 301 on both sides prevent the sensor from being touched by external objects during operation, which would cause the mounting assembly 2 to fall off.

[0028] The fixing component 4 includes a fixing column 401 and a thread 402. The fixing column 401 is made of stainless steel and the fixing column 401 is provided with a thread 402 on its exterior. The fixing column 401 is rotated and snapped into the fixing groove 203 by the thread 402, which is beneficial for fixing the detection component 5 and improving the detection accuracy.

[0029] The detection component 5 includes a sensor body 501, a collar 502, and an isolation diaphragm 503. The sensor body 501 is disposed inside the housing 101, the collar 502 is movably engaged inside the outer casing 201, and the isolation diaphragm 503 is made of stainless steel and is fixedly sleeved inside the collar 502. The surface of the isolation diaphragm 503 is polished to Ra≤0.8μm, which helps to prevent bacterial growth, facilitates cleaning, and improves the hygiene of the sensor's interior.

[0030] The working principle of this utility model:

[0031] First, the sensor is fixedly installed in the designated position via flange 102, and the top of the fixed column 401 is connected to the test object. The test object enters the fixed column 401 and reaches the collar 502, applying pressure to the surface of the collar 502, causing the collar 502 to undergo slight deformation. The sensor body 501 detects and collects the data for processing.

[0032] Secondly, since both the fixed column 401 and the isolation diaphragm 503 are made of stainless steel, bacterial growth can be avoided and cleaning can be made easier, thus improving the hygiene of the sensor's interior.

[0033] Finally, press the limiting plate 303 into the housing 101. The limiting plate 303, the slide bar 302 and the push ball 304 move towards the fixing block 204, pressing the fixing block 204 into the housing 201. The fixing block 204 compresses the spring 205. After the fixing block 204 enters the housing 201, the mounting assembly 2 can be taken out upwards to disassemble and clean the sensor.

[0034] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

[0035] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
