Description

Technical Field

[0001] The utility model relates to the technical field of ozone detection, in particular to a handheld ozone concentration detector. Background Art

[0002] Ozone concentration detectors are used to detect ozone concentration, and their frequency of use is also relatively high in the chemical industry. Currently, ozone concentration detectors are mainly used to detect ozone concentration at the outlet of ozone generators. During the ozone production process, technical indicators such as the concentration value, output, and production efficiency of ozone gas are affected by the temperature, humidity, and pressure of the gas source.

[0003] Most handheld ozone concentration detectors are integrally designed, and there is no protection device on their surface. The air sampling nozzle is set relatively protruding, making it easy to collide with objects in the environment during the carrying process, resulting in damage to the air sampling nozzle. The traditional method is to sleeve a protective plug outside the air sampling nozzle. During use, it is necessary to manually remove the protective plug, and the protective plug is small and easily lost after being removed, affecting subsequent use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a handheld ozone concentration detector to solve the above technical problems.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A handheld ozone concentration detector, including a housing and an air sampling nozzle provided at the upper end of the housing. A display screen and buttons are respectively provided on the front side of the housing. A protective component for protecting the air sampling nozzle is rotatably provided on the rear side of the housing. An elastic band is provided on the rear side of the housing. The rear side of the protective component is fixedly connected to the lower end of the outer surface of the elastic band through a pulling rope;

[0007] The protective component includes a back plate rotatably provided on the rear side of the housing and a top plate rotatably provided at the upper end of the back plate. The back plate and the top plate are both connected through a reset hinge, and a sealing member is provided on one side of the back plate.

[0008] As a further description of the above technical scheme:

[0009] The sealing member includes a sealing gasket and a fixing frame fixedly provided on one side of the back plate. A placement groove for placing the sealing gasket is provided on the surface of the fixing frame.

[0010] As a further description of the above technical scheme:

[0011] A limiting rod is movably penetrated through the surface of the top plate, and a limiting hole matching the limiting rod is provided on the surface of the fixing frame.

[0012] As a further description of the above technical scheme:

[0013] The middle part of the limiting rod is threaded and is threadedly connected to the top plate.

[0014] As a further description of the above technical solution:

[0015] A handle is fixedly arranged on the outer surface of the elastic band, and the pulling rope is located inside the handle.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0017] In the present utility model, by arranging an elastic band, a pulling rope and a protection component, when the detector is not in use, the protection component keeps protecting the gas sampling nozzle. When in use, the staff puts their hand into the inner side of the elastic band, so that the pulling rope is stretched under tension, driving the protection component to flip, making the gas sampling nozzle completely exposed, which is convenient for the staff to operate, avoiding the traditional protection plug that needs to be manually removed, being rather troublesome, and having no place to store and being easy to lose after being removed.

[0018] In the present utility model, by arranging a sealing member, the gas sampling nozzle is effectively sealed and protected, preventing the gas sampling nozzle from adhering to dust and breeding bacteria, which affects the use of the ozone concentration detector. Through the mutual cooperation of the limiting rod and the limiting hole, the stability of the closing of the top plate is effectively ensured, and the effect of pressing and fixing the sealing gasket is ensured. By flipping the top plate, it is convenient for the staff to replace the sealing gasket. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the protection scope of the present utility model.

[0024] As shown in FIGS. 1-3, a handheld ozone concentration detector includes a housing 1 and a gas sampling nozzle 4 provided at the upper end of the housing 1. A display screen 3 and buttons 2 are respectively provided on the front side of the housing 1. A protection component for protecting the gas sampling nozzle 4 is rotatably provided on the rear side of the housing 1. An elastic band 7 is provided on the rear side of the housing 1. The rear side of the protection component is fixedly connected to the lower end of the outer surface of the elastic band 7 through a pulling rope 8.

[0025] The protection component includes a back plate 5 rotatably provided on the rear side of the housing 1 and a top plate 6 rotatably provided at the upper end of the back plate 5. Both the back plate 5 and the top plate 6 are connected through a return hinge. A sealing member is provided on one side of the back plate 5. During use, the staff inserts their hand into the inner side of the elastic band 7, so that the pulling rope 8 is stretched under tension, driving the protection component to flip, making the gas sampling nozzle completely exposed, facilitating the staff to perform operations. After the operation is completed, the hand is removed from the inner side of the elastic band 7, and the back plate 5 automatically resets under the return hinge, achieving the effect of protecting the gas sampling nozzle 4, avoiding the traditional protection plug that needs to be manually removed, which is rather troublesome, and there is no place to store it after removal and it is easy to lose.

[0026] Further, the sealing member includes a sealing gasket 12 and a fixing frame 10 fixedly provided on one side of the back plate 5. A placement groove 11 for placing the sealing gasket 12 is formed on the surface of the fixing frame 10, effectively sealing and protecting the gas sampling nozzle 4, avoiding the gas sampling nozzle from adhering to dust and breeding bacteria, which affects the use of the ozone concentration detector.

[0027] Further, a limiting rod 13 is movably penetrated through the surface of the top plate 6. A limiting hole 14 matching the limiting rod 13 is formed on the surface of the fixing frame 10.
