Sensor protective cover

Abstract

This invention provides a protective sleeve for a sensor, comprising a body and a buffer component. The body has an internal cavity for accommodating the sensor. The buffer component is connected to the outer peripheral wall of the body and protrudes outward relative to the outer peripheral wall. Both the body and the buffer component are made of flexible material. By providing a buffer component on the outer peripheral wall of the body, which protrudes outward, the protective sleeve absorbs the impact force primarily through the elastic deformation of the buffer component during a collision, thereby achieving a shock-absorbing effect and protecting the sensor, thus enhancing the buffering function of the protective sleeve.

Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment verification, and in particular to a protective cover for a sensor. Background Technology

[0002] In pharmaceutical manufacturing, it is necessary to periodically validate production-related procedures and equipment to ensure they operate normally according to set requirements and produce compliant drugs. For example, it is essential to periodically validate rubber stopper and aluminum cap cleaning and sterilization machines using sensors to demonstrate that during the cleaning and sterilization process, the temperature distribution within the sterilized container is uniform, and the surfaces in contact with the product achieve the expected sterilization effect. If the sterilization temperature is too low or the temperature distribution within the sterilization equipment is uneven, the rubber stopper and aluminum cap cleaning and sterilization machine will fail to achieve the expected sterilization effect, and aseptic production cannot be effectively guaranteed. Therefore, periodic validation of operating procedures and equipment is particularly important.

[0003] During periodic verification of operating procedures and equipment, the unique drum design of the rubber stopper and aluminum cap cleaning and sterilization machine makes sensor placement extremely inconvenient. The sensors cannot be fixed to the inner wall of the drum, causing them to flip, roll, and collide with the drum during operation. Since sensors are precision devices and expensive, they are easily damaged by these collisions within the drum. Most commercially available sensor protective sleeves are cylindrical silicone sleeves, with the sensors placed inside. Relying on the cushioning effect of the silicone for shock absorption, their protective effect is relatively poor. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defect of poor protective effect of existing sensor protective covers and to provide a sensor protective cover.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A protective cover for a sensor includes a body and a buffer. The body has an interior cavity for accommodating the sensor. The buffer is connected to the outer peripheral wall of the body and protrudes outward relative to the outer peripheral wall of the body. Both the body and the buffer are made of flexible material.

[0007] In this technical solution, a buffer is provided on the outer peripheral wall of the main body. The buffer protrudes outward. When a collision occurs, the protective sleeve mainly relies on the elastic deformation of the buffer to absorb the impact force, thereby playing a shock absorption role and achieving the protection effect of the sensor, which can enhance the buffering effect of the protective sleeve.

[0008] Preferably, the buffer includes a plurality of protrusions, which are respectively connected to the outer peripheral wall of the body.

[0009] Preferably, the buffer includes a first protrusion and a second protrusion, wherein the length of the first protrusion protruding relative to the outer peripheral wall of the body is less than the length of the second protrusion protruding relative to the outer peripheral wall of the body.

[0010] In this technical solution, by setting a first protrusion and a second protrusion with different protrusion lengths, the protrusion that plays the main role will also be different when the collision intensity is different. Specifically, when the collision intensity is low, the longer second protrusion will deform first and play a buffering role. When the collision intensity is high, the first protrusion and the second protrusion can play a buffering role together.

[0011] Preferably, the first protrusion and the second protrusion are arranged at intervals on the outer peripheral wall of the body.

[0012] In this technical solution, by setting the first protrusion and the second protrusion at intervals, that is, each first protrusion is surrounded by the second protrusion and each second protrusion is surrounded by the first protrusion, a synergistic deformation can be formed, which can make the buffering capacity of the protective sleeve more uniform and avoid poor buffering effect of local areas against high-intensity or low-intensity collisions.

[0013] Preferably, the first protrusions are evenly distributed on the outer peripheral wall of the body.

[0014] Preferably, the second protrusion and the second protrusion are evenly arranged on the outer peripheral wall of the body.

[0015] Preferably, the cross-section of the protrusion gradually decreases along the axis of the protrusion away from the body.

[0016] In this technical solution, by setting the cross-section of the protruding post to gradually decrease, the outermost part of the protective sleeve has the lowest rigidity and gradually increases inward, which can buffer the impact force during a collision in stages, resulting in a better buffering effect.

[0017] Preferably, the protruding pillar includes a trunk and multiple branches, with the multiple branches respectively connected to the trunk to form a tree-like structure.

[0018] Preferably, the body has an opening that extends inward from the outer wall of the body into the cavity, the size of the opening being smaller than the size of the sensor, and the opening being used to insert the sensor into the cavity or to remove the sensor from the cavity.

[0019] In this technical solution, by setting the opening to be smaller than the size of the sensor, the sensor can be placed into the cavity through the elastic deformation of the protective sleeve, and the sensor is not easy to fall out without the need for a cover.

[0020] Preferably, the outer peripheral wall of the body has a cylindrical structure.

[0021] Preferably, the cavity includes a first cavity and a second cavity, the first cavity being used to accommodate the main body of the sensor, the second cavity being used to accommodate the sensing part of the sensor, the second cavity being in communication with the outside, the size of the first cavity being smaller than the size of the main body, and the size of the second cavity being larger than the size of the sensing part.

[0022] In this technical solution, by setting the size of the first cavity to be smaller than the size of the main body, the protective sleeve can better wrap the main body. By setting the size of the second cavity to be larger than the size of the main body, the outer side of the sensing part can come into contact with the environment to be detected, resulting in more accurate detection results.

[0023] Preferably, the body includes a first part and a second part, the first cavity is located in the first part, the second cavity is located in the second part, the outer peripheral walls of the first part and the second part are both cylindrical structures, and the wall thickness of the first cavity is the same as the wall thickness of the second cavity.

[0024] In this technical solution, the wall thickness of the first cavity is the same as that of the second cavity, and the protection effect on the sensing part and the main body is basically the same. However, the size of the sensing part of the sensor is usually smaller than that of the main body. Compared with setting the protective sleeve as a columnar structure, setting the wall thickness of the first cavity to be the same as that of the second cavity can save the raw materials of the protective sleeve and reduce the cost without sacrificing the protection effect.

[0025] The positive and progressive effects of this utility model are as follows: by setting a buffer member on the outer peripheral wall of the main body, the buffer member protrudes outward. When a collision occurs, the protective sleeve mainly relies on the elastic deformation of the buffer member to absorb the impact force, thereby playing a shock absorption role and achieving the protection effect of the sensor, which can enhance the buffering effect of the protective sleeve.

[0040] Sensing section 202 Detailed Implementation

[0041] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0042] like Figures 1-3 As shown, this embodiment provides a protective sleeve 100 for a sensor 200. The protective sleeve 100 includes a body 1 and a buffer member 2. The body 1 has an internal cavity for accommodating the sensor 200. The buffer member 2 is connected to the outer peripheral wall of the body 1 and protrudes outward relative to the outer peripheral wall of the body 1. Both the body 1 and the buffer member 2 are made of flexible material. By providing the buffer member 2 on the outer peripheral wall of the body 1, and by having the buffer member 2 protrude outward, the protective sleeve 100 mainly relies on the elastic deformation of the buffer member 2 to absorb the impact force during a collision, thereby playing a shock-absorbing role and achieving a protective effect for the sensor 200, thus enhancing the buffering effect of the protective sleeve 100.

[0043] Specifically, the buffer 2 includes multiple protrusions, each connected to the outer peripheral wall of the body 1. The buffer 2 includes a first protrusion 21 and a second protrusion 22, where the first protrusion 21 protrudes less than the second protrusion 22. By using first and second protrusions with different protrusion lengths, different protrusions play a primary role when the impact intensity varies. Specifically, at lower impact intensity, the longer second protrusion 22 deforms first, providing a buffering effect; at higher impact intensity, both the first and second protrusions work together to provide a buffering effect.

[0044] Of course, in other embodiments, the protrusions may be set to the same length, or the lengths of the protrusions may be more varied, which will not be elaborated here.

[0045] In this embodiment, the first protrusion 21 and the second protrusion 22 are arranged at intervals on the outer peripheral wall of the body 1, and are also evenly arranged on the outer peripheral wall of the body 1. By arranging the first protrusion 21 and the second protrusion 22 at intervals, that is, each first protrusion 21 is "surrounded" by the second protrusion 22, and each second protrusion 22 is "surrounded" by the first protrusion 21, synergistic deformation can be formed, making the buffering capacity of the protective sleeve 100 more uniform and avoiding poor buffering effect of high-intensity or low-intensity collisions in local areas.

[0046] Furthermore, along the axis of the protruding post away from the body 1, the cross-section of the protruding post gradually decreases. By setting the cross-section of the protruding post to gradually decrease, the outermost rigidity of the protective sleeve 100 is the lowest, and gradually increases inward, which can buffer the impact force during a collision in stages, resulting in a better buffering effect.

[0047] In other embodiments, the protrusions may be configured in other shapes, for example, the protrusions may include a trunk and multiple branches, the multiple branches being connected to the trunk to form a tree structure.

[0048] In this embodiment, as Figure 1 As shown, the main body 1 has an opening 101 that extends inward from the outer wall of the main body 1 into the cavity. The size of the opening 101 is smaller than the size of the sensor 200. The opening 101 is used to insert the sensor 200 into the cavity or remove the sensor 200 from the cavity. Specifically, the opening 101 can be formed by cutting. By setting the opening 101 to be smaller than the size of the sensor 200, the sensor 200 can be inserted into the cavity by the elastic deformation of the protective sleeve 100, and the sensor 200 is less likely to fall out without the need for a cap.

[0049] Specifically in this embodiment, such as Figure 2 As shown, the cavity includes a first cavity 11 and a second cavity 12. The first cavity 11 is used to accommodate the main body 201 of the sensor 200, and the second cavity 12 is used to accommodate the sensing part 202 of the sensor 200. The second cavity 12 is connected to the outside. The size of the first cavity 11 is smaller than the size of the main body 201, and the size of the second cavity 12 is larger than the size of the sensing part 202. By setting the size of the first cavity 11 to be smaller than the size of the main body 201, the protective sleeve 100 can provide better coverage for the main body 201. By setting the size of the second cavity 12 to be larger than the size of the main body 201, the outer side of the sensing part 202 can contact the environment to be detected, resulting in more accurate detection results.

[0050] In this embodiment, the outer peripheral wall of the body 1 is a cylindrical structure. The sensing portion 202 of the sensor 200 is typically smaller than the size of the main body 201, and the wall thickness of the second cavity 12 is greater than the wall thickness of the first cavity 11.

[0051] Of course, in other embodiments, the body 1 includes a first part and a second part, with a first cavity 11 located in the first part and a second cavity 12 located in the second part. The outer peripheral walls of both the first and second parts are cylindrical structures, and the wall thickness of the first cavity 11 is the same as that of the second cavity 12. Since the wall thickness of the first cavity 11 and the second cavity 12 are the same, the protection effect on the sensing part 202 and the main body 201 is essentially the same. However, the size of the sensing part 202 of the sensor 200 is typically smaller than the size of the main body 201. Compared to setting the entire protective sleeve 100 as a cylindrical structure, setting the wall thickness of the first cavity 11 to be the same as that of the second cavity 12 can save raw materials for the protective sleeve 100 and reduce costs without sacrificing the protective effect.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
