Abstract
Description
Technical Field
[0001] This utility model belongs to the field of livestock disease prevention and control technology, and in particular relates to an environmental pathogen monitoring instrument. Background Technology
[0002] Disease prevention and control is always the top priority of farm work. In order to prevent the high breeding costs caused by diseases, it is necessary to detect viruses early and treat them in time to reduce breeding risks. Therefore, an environmental pathogen monitoring instrument is needed.
[0003] The existing environmental monitoring instruments have the following technical disadvantages: they have built-in detection functions, are complex in structure, and are costly; in addition, they lack self-testing functions, so it is unknown whether sampling cotton has been placed or whether the fan is working properly. Utility Model Content
[0004] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides an environmental pathogen monitoring instrument, which solves the above problems.
[0005] To achieve the above objectives, this utility model provides an environmental pathogen monitoring instrument, comprising:
[0006] air duct;
[0007] The negative pressure drive module is located inside the air duct;
[0008] A bracket is positioned between the negative pressure drive module and the air inlet of the air duct;
[0009] A reciprocating module is mounted on the support and is capable of reciprocating relative to the support;
[0010] The detection module is used to detect whether sampling cotton is placed on the reciprocating module;
[0011] When the negative pressure drive module is activated and a sampling cotton is placed on the reciprocating module, a negative pressure is formed in the space between the reciprocating module and the negative pressure drive module, which drives the reciprocating module to move, thereby triggering the detection module.
[0012] Compared with existing technologies, this application has the following advantages: During use, the negative pressure drive module operates, drawing ambient gas into the air duct through the air inlet, allowing the air to contact the sampling cotton. Simultaneously, because the sampling cotton is placed on the reciprocating module, a pressure difference is created between the space between the reciprocating module and the negative pressure drive module and atmospheric pressure. This causes the reciprocating module to move towards the support. When the reciprocating module reaches the designated position, the detection module is triggered, completing the sampling process. The negative pressure drive module then operates for a specified period to complete gas sampling. After sampling, the negative pressure drive module stops operating, the reciprocating module resets, and the operator can then remove the sampling cotton, completing one sampling cycle. It should be noted that when the negative pressure drive module is operating, the detection module triggers, indicating that sampling cotton is placed on the reciprocating module. Conversely, when sampling cotton is placed on the reciprocating module, the detection module does not trigger, indicating that the negative pressure drive module is not operating.
[0013] Therefore, the technical solution of this application is not only simple in structure, low in cost, and easy to operate, but also able to detect whether sampling cotton is placed and whether the negative pressure drive module is working properly, thus ensuring the accuracy of sampling.
[0014] Furthermore, the reciprocating module includes a hollowed-out tray and an elastic element, the tray being fixed to the bracket by the elastic element.
[0015] Furthermore, the elastic element includes a spring and a guide rod. The spring is fitted onto the guide rod. One end of the guide rod is fixedly connected to the tray, and the other end is movably connected to the bracket, so that when the tray moves toward the bracket, the tray moves along the guide rod toward the bracket to compress the spring.
[0016] Furthermore, the detection module includes a magnet and a magnetic switch. The magnet is disposed on the tray, and the magnetic switch is disposed on the support, with the magnet and the magnetic switch corresponding in position, or the magnetic switch is disposed on the tray, and the magnet is disposed on the support, with the magnet and the magnetic switch corresponding in position; wherein, when the tray moves toward the support, the magnetic switch senses the magnet and is triggered.
[0017] Furthermore, the magnetic switch is a Hall switch, with its sensing surface facing the magnet and the trigger distance adjustable.
[0018] Furthermore, it also includes a door opening module for easy access to and from the sampling cotton.
[0019] Furthermore, the door opening module is positioned above the reciprocating module and on the side wall of the air duct.
[0020] Furthermore, the door opening module includes a sample receiving port, and a cover plate is provided at the sample receiving port.
[0021] Furthermore, it also includes a magnetic door catch, which is fixed at the sample collection port and is used to engage with the cover plate.
[0022] Furthermore, the negative pressure drive module is a potting waterproof fan. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0030] like Figures 1-3 As shown, this utility model discloses an environmental pathogen monitoring instrument, comprising:
[0031] Air duct 1;
[0032] Negative pressure drive module 2 is located inside the air duct 1;
[0033] The bracket 3 is located between the negative pressure drive module 2 and the air inlet of the air duct 1;
[0034] The reciprocating module 4 is mounted on the support 3 and can reciprocate relative to the support 3.
[0035] Detection module 5 is used to detect whether sampling cotton is placed on reciprocating module 4;
[0036] When the negative pressure drive module 2 is started and the sampling cotton is placed on the reciprocating module 4, a negative pressure is formed in the space between the reciprocating module 4 and the negative pressure drive module 2, which drives the reciprocating module 4 to move, thereby triggering the detection module 5.
[0037] Compared with the prior art, this application has the following advantages: When in use, the negative pressure drive module 2 works, drawing gas from the surrounding environment into the air duct 1 through the air inlet, allowing the air to come into contact with the sampling cotton; at the same time, because the sampling cotton is placed on the reciprocating module 4, a pressure difference is generated between the space between the reciprocating module 4 and the negative pressure drive module 2 and the atmospheric pressure, so the reciprocating module 4 will move towards the support 3. When the reciprocating module 4 moves to the designated position, the detection module 5 is triggered to complete the sampling work. The negative pressure drive module 2 works for a period of time as specified, that is, the gas sampling is completed. After the sampling is completed, the negative pressure drive module 2 stops working, the reciprocating module 4 is reset, and the operator can then remove the sampling cotton, completing one sampling process.
[0038] It should be noted that when the negative pressure drive module 2 is working, the detection module 5 is triggered, indicating that a sampling cotton is placed on the reciprocating module 4. Conversely, when a sampling cotton is placed on the reciprocating module 4, the detection module 5 is not triggered, indicating that the negative pressure drive module 2 is not working, thus determining whether there is an abnormality in the negative pressure drive module 2.
[0039] Therefore, the technical solution of this application is not only simple in structure, low in cost, and easy to operate, but also able to detect whether sampling cotton is placed and whether the negative pressure drive module 2 is working properly, thus ensuring the accuracy of sampling.
[0040] Among them, the negative pressure drive module 2 is a glue-filled waterproof fan, or it can be a blower or other negative pressure device. The glue-filled waterproof fan has a high level of protection and corrosion resistance, and a long service life.
[0041] Following the above embodiment, more specifically, the reciprocating module 4 includes a hollow tray 41 and an elastic element. The tray 41 is fixed to the bracket 3 by the elastic element. Because the tray 41 has a hollow structure, when no collecting cotton is placed on it, the upper and lower spaces of the tray 41 are connected, preventing a pressure difference between the space between the reciprocating module 4 and the negative pressure drive module 2 and atmospheric pressure. Therefore, the reciprocating module 4 will not move, and the detection module 5 will not be triggered, thus determining that no collecting cotton is placed on the tray 41. Conversely, when collecting cotton is present, the upper and lower spaces of the tray 41 become disconnected, and under negative pressure, the reciprocating module 4 moves, triggering the detection module 5, thus determining that collecting cotton is placed on the tray 41.
[0042] Following the above embodiment, more specifically, the elastic element includes a spring 42 and a guide rod 43. The spring 42 is fitted onto the guide rod 43. One end of the guide rod 43 is fixedly connected to the tray 41, and the other end is movably connected to the bracket 3. When the tray 41 moves toward the bracket 3, the tray 41, carrying the guide rod 43, moves toward the bracket 3, compressing the spring 42. The spring 42 is fitted onto the guide rod 43 between the bracket 3 and the tray 41. The guide rod 43 passes through the bracket 3 and is clearance-fitted with it. Therefore, when the tray 41 moves toward the bracket 3, it drives the guide rod 43 to move toward the bracket 3, compressing the spring 42. Conversely, when the tray 41 loses external force, it will reset under the action of the spring 42.
[0043] Following the above embodiment, more specifically, the detection module 5 includes a magnet 51 and a magnetic switch 52. The magnet 51 is disposed on the tray 41, and the magnetic switch 52 is disposed on the bracket 3, with the positions of the magnet 51 and the magnetic switch 52 corresponding, or the magnetic switch 52 is disposed on the tray 41, and the magnet 51 is disposed on the bracket 3, with the positions of the magnet 51 and the magnetic switch 52 corresponding; wherein, when the tray 41 moves toward the bracket 3, the magnetic switch 52 senses the magnet 51 and is triggered.
[0044] Regardless of whether the magnetic switch 52 or the magnet 51 moves towards each other, the magnetic switch 52 will be triggered when the two come into contact, thereby sending a signal.
[0045] Following the above embodiment, a more preferable embodiment is that the magnetic switch 52 is a Hall switch, with its sensing surface facing the magnet 51, and the trigger distance is adjustable. For example, the magnetic switch 52 can be fixed to a telescopic frame, which may include a fixed frame and a movable frame. The fixed frame and the movable frame are threaded together, and the magnetic switch 52 is fixed to the movable frame. Adjusting the position of the movable frame adjusts the position of the magnetic switch 52. By using a Hall switch, the trigger sensitivity is improved, and by adjusting the trigger distance, the trigger distance can be adjusted according to actual conditions.
[0046] Following the above embodiments, more specifically, it also includes a door opening module 6 for easy access to and placement of the sampling cotton.
[0047] Following the above embodiment, more specifically, the door opening module 6 is disposed above the reciprocating module 4 and located on the side wall of the air duct 1. The design of the door opening module 6 facilitates the placement and removal of the sampling cotton.
[0048] Following the above embodiment, more specifically, the door opening module 6 includes a sample receiving port 61, and a cover plate 62 is provided at the sample receiving port 61. Opening the cover plate 62 allows the sample cotton to be placed or removed through the sample receiving port 61.
[0049] Following the above embodiment, more specifically, it also includes a magnetic door catch 63, which is fixed at the sample receiving port 61 and is used to engage with the cover plate 62. The design of the magnetic door catch 63 facilitates the opening and closing of the cover plate 62.
[0050] The workflow for this application is as follows:
[0051] This invention allows personnel to control the sample collection and placement. During sample placement, the negative pressure drive module 2 stops working, and the personnel manually open the cover plate 62, placing the sampling cotton evenly on the tray 41 through the sample collection port 61. The cover plate 62 is then closed, engaging with the magnetic door catch 63. The negative pressure drive module 2 is activated, creating a negative pressure between the negative pressure drive module 2 and the sampling cotton, compressing the spring 42. The sampling cotton, tray 41, and magnet 51 move downwards, triggering the magnetic switch 52 and completing the placement. After a certain period, pathogen collection is completed, and the personnel control the sample collection. The negative pressure drive module 2 stops working, and the personnel manually open the cover plate 62, retrieving the sampling cotton through the sample collection port 61. Simultaneously, new sampling cotton is evenly placed on the tray 41, and the cover plate 62 is closed, engaging with the magnetic door catch 63, completing one cycle and entering the next pathogen collection cycle.
[0052] Therefore, this application can not only accurately identify whether there is sampling cotton in the current device, but also has simple and reliable control logic, and is easy to install and replace.
[0053] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
