Description

Technical Field

[0001] This utility model relates to the field of dust particle counter technology, specifically a portable handheld dust particle counter. Background Technology

[0002] In fields such as industrial production, medical cleanrooms, and electronics manufacturing, dust particle concentration detection is a crucial step in ensuring environmental cleanliness. Traditional dust particle counters are mostly benchtop structures, which are large, heavy, and rely on fixed power supplies, making them unsuitable for scenarios such as on-site inspections and mobile monitoring.

[0003] According to a handheld dust particle counter disclosed on the patent website (authorization announcement number: CN210037536U), "This utility model discloses a handheld dust particle counter, relating to the technical field of dust particle counters. The handheld dust particle counter includes a counter housing and a pull ring. The pull ring is fixedly connected to the top of the counter housing, and a spring is fixedly connected to the bottom of the pull ring. A fixing plate is fixedly connected to the end of the spring away from the pull ring. Both the fixing plate and the counter housing have first screw holes inside. The fixing plate is fixedly connected to the counter housing by first screws. This handheld dust particle counter uses elastic material for both the fixing strap and the wristband, giving them good elasticity. The combination of the fixing strap and the wristband allows the counter to be fixed to the user's arm, effectively preventing it from falling due to a loose grip, thus effectively enhancing the protection of the counter." Based on the above, the applicant believes the following deficiencies exist: This handheld dust particle counter includes a counter housing and a pull ring. Through the use of a fixing strap and wristband, the counter can be secured to the user's arm, effectively preventing it from falling due to a loose grip. This significantly enhances the counter's protection. However, it lacks portability and cannot adapt to mobile detection scenarios. Relying solely on a handheld method, it cannot be fixed to auxiliary carriers such as backpacks or work bags. Its limited carrying options and insufficient adaptability mean it cannot accommodate different hand sizes, potentially resulting in slippage when held too loosely or difficulty in gripping when held too tightly, leading to insufficient grip stability. Utility Model Content

[0004] The purpose of this invention is to provide a portable handheld dust particle counter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable handheld dust particle counter, comprising a dust particle counter, a detection head mounted on the top right side of the dust particle counter, a portable mechanism provided on the surface of the dust particle counter, the portable mechanism comprising a portable component and a support component, an additional detection tube mounting mechanism provided on the surface of the detection head, and an antenna mounted on the top left side of the dust particle counter; The portable component includes a side frame mounted on the bottom left and right sides of the dust particle counter. A spring post is fixedly connected to the outer end of the inner side frame, and a clamping plate is fixedly connected to the inner end of the spring post. A first sponge pad is fixedly connected to the surface of the clamping plate, and a second sponge pad is fixedly connected to the inner end of the inner side frame. A connecting seat is mounted at the center of the top rear end of the dust particle counter, and a rope buckle is fixedly connected to the top of the connecting seat.
