Description

Technical Field

[0001] This utility model relates to the field of dust prevention for instruments and meters, and in particular to an instrument and meter with a dustproof structure. Background Technology

[0002] Instruments and meters are tools or equipment used to detect, measure, observe, and calculate various physical quantities, material composition, physical property parameters, etc.

[0003] A search revealed Chinese Patent Publication No. CN210489254U, which discloses an instrument with a dustproof structure. The instrument includes a housing, which is a rectangular hollow box. Connecting rods are fixedly installed inside the housing cavity. Side plates are fixedly connected to the bottom ends of the two connecting rods. The length and height of the side plates are the same as the length and height of the housing. An instrument is fixedly installed on the top of the side plates. The connecting rods consist of a sleeve and a rod sleeve, with the rod sleeved inside the sleeve. The sleeve and rod are fixedly connected to the inner wall of the housing cavity and the side plates, respectively. A drawer is fixedly installed on the outer left side wall of the housing. The fan has a filter chamber on the left side wall of the casing, which is connected to the output end of the exhaust fan. A rotating magnet (a cylindrical magnet) is located on the left side of the filter chamber, with bearings fitted at its top and bottom. Two bearings are fixedly installed at the top and bottom of the left side of the filter chamber. Fan blades are fixedly installed on the wall of the rotating magnet. A vibrating filter screen is located in the right side cavity of the filter chamber, with sliders fitted at its top and bottom. Sliding grooves corresponding to the sliders are formed at the top and bottom of the right side of the filter chamber, and the two sliders engage with the two grooves in the filter chamber. This invention uses the back-and-forth vibration of the vibrating filter screen to shake dust and dirt from the screen holes into a dust collection chamber, thus collecting and processing the filtered dust. This solves the problem of filter screens being easily clogged by dust and dirt, leading to a reduction in the lifespan of instruments.

[0004] In the above-mentioned technology, the dust and grime inside the screen holes of the vibrating filter are shaken off and fall into the dust collection bin by the back-and-forth vibration of the vibrating filter screen, and the filtered dust is collected and processed. However, the dust attached to the vibrating filter screen is shaken off and blown away by the continuously output airflow, which makes it difficult for the dust to fall into the dust collection bin and is inconvenient to collect. Therefore, an instrument with a dustproof structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an instrument with a dustproof structure, which aims to improve the problem in the prior art where the shaken dust is blown away by the continuously output airflow, making it difficult for the dust to fall into the dust collection chamber and thus inconvenient to collect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an instrument with a dustproof structure, comprising a housing, a side plate rotatably connected to the outer wall of the right end of the housing, an exhaust fan fixedly connected to the outer wall of the front end of the housing, a bracket rotatably connected to the inner wall of the front end of the housing, a fixing rod fixedly connected to the inner wall of the bottom end of the bracket, a vibrating filter elastically connected to the inner wall of the bottom end of the bracket via a spring, a fixing block fixedly connected to the outer wall of the front end of the vibrating filter, a rotating assembly provided on the inner wall of the front end of the housing for vibrating the vibrating filter, an opening and closing assembly provided on the inner wall of the front end of the housing for convenient dust cleaning, an exhaust net fixedly connected to the inner wall of the rear end of the housing, and a motor fixedly connected to the inner wall of the front end of the housing.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the vibration filter to be cleaned is rotated to the lower side by the rotation of motor two, so that the vibration filter to be cleaned is in a closed space. Motor one drives the rotating shaft to rotate, and the rotating shaft drives the connecting rod and roller to rotate. When the roller contacts the fixed block on the outer wall of the front end of the vibration filter, the roller rolls on the outer wall of the fixed block, causing the fixed block to move backward, thereby squeezing spring one. As the roller continues to rotate and moves away from the fixed block, the elastic force of spring one causes the vibration filter to pop forward, realizing the vibration of the vibration filter and shaking off the dust on the vibration filter, which facilitates the collection of dust on the vibration filter.

[0023] 2. In this utility model, the upper outer wall of the rotating plate is rotatably connected to the front inner wall of the housing. When the rotating plate is in a vertical state, the opening is closed. When it is necessary to clean the dust, the locking block is pulled out from the right inner wall of the rotating plate, and then the rotating plate is rotated 90 degrees counterclockwise and fixed in position by the locking block. At this time, the internal dust can be easily cleaned. Attached Figure Description

[0034] Reference Figure 2 , Figure 4 and Figure 5 The rotating assembly includes a motor 3, which drives the rotation of a rotating shaft 12. The outer wall of the motor 3 is fixedly connected to the inner wall of the front end of the housing 1. The rotating shaft 12 is rotatably connected to the inner wall of the front end of the housing 1. The operation of the rotating shaft 12 drives the connecting rod 10 and the roller 16 to rotate. The inner wall of the bottom end of the rotating shaft 12 is fixedly connected to the output shaft of the motor 3. The outer wall of the right end of the rotating shaft 12 is fixedly connected to the connecting rod 10, which provides support for the roller 16. The connecting rod 10 drives the roller 16 to rotate through the rotation of the rotating shaft 12. The roller 16 is provided on the inner wall of the right end of the connecting rod 10. The roller 16 rotates with the rotation of the connecting rod 10. When the roller 16 contacts the outer wall of the front end of the fixed block 15, the roller 16 rolls on the outer wall of the fixed block 15, causing the fixed block 15 to move backward.

[0035] Working principle: A side plate 2 is rotatably connected to the outer wall of the right end of the housing 1. Instruments are mounted on the side plate 2. The side plate 2 can rotate 90 degrees counterclockwise to completely close with the housing 1, so that the instruments on the side plate 2 are completely closed in the sealed cavity formed by the housing 1 and the side plate 2, thus providing initial dust protection. An exhaust fan 5 is fixedly connected to the outer wall of the front end of the housing 1. The exhaust fan 5 delivers external air into the housing 1. After the air enters the housing 1, it is filtered by the vibrating filter 11 on the bracket 8. The filtered air is discharged from the air outlet 6 on the inner wall of the rear end of the housing 1, forming an air circulation to ensure that the instruments are in a relatively clean air environment. A rotating assembly is provided on the inner wall of the front end of the housing 1. The rotating assembly includes a motor 3, a rotating shaft 12, a connecting rod 10, and a roller 16. The operation of the motor 3 drives the rotating shaft 12 to rotate. The connecting rod 10 and roller 16 are driven to rotate. When the roller 16 contacts the fixed block 15 on the outer wall of the front end of the vibrating filter 11, the roller 16 rolls on the outer wall of the fixed block 15, causing the fixed block 15 to move backward, thereby squeezing the spring 14. As the roller 16 continues to rotate and moves away from the fixed block 15, the elastic force of the spring 14 causes the vibrating filter 11 to pop forward, realizing the vibration of the vibrating filter 11 and shaking off the dust on the vibrating filter 11. An opening and closing assembly is provided on the inner wall of the front end of the housing 1. The opening and closing assembly includes a rotating plate 4 and a locking block 7. The upper outer wall of the rotating plate 4 is rotatably connected to the inner wall of the front end of the housing 1. When the rotating plate 4 is in a vertical state, the opening is closed. When it is necessary to clean the dust, the locking block 7 is pulled out from the inner wall of the right end of the rotating plate 4, and then the rotating plate 4 is rotated ninety degrees counterclockwise and fixed in position by the locking block 7. At this time, the internal dust can be easily cleaned.
