Description

Technical Field

[0001] This utility model relates to the field of gas detection equipment, specifically to a sliding cover alcohol tester. Background Technology

[0002] Breathalyzers, as a safety detection tool, are widely used in road traffic, production safety, and other fields. Traditional breathalyzers typically have exposed detection heads, making them susceptible to damage or inaccurate readings due to impacts, dust accumulation, or contamination. While some products use a cover for protection, existing covers are mostly flip-tops or simple plug-in designs, which suffer from inconvenient opening, easy wear of connecting parts, and the inability to automatically activate the device upon opening.

[0003] Furthermore, some designs with sliding cover structures often have a poor sliding experience, either being too loose or having excessive resistance. Their on / off triggering mechanisms also mostly rely on direct mechanical contact triggering. This method of direct contact and application of pressure can easily lead to wear, fatigue, or even failure of the switch and triggering structure over long-term use, affecting the reliability and service life of the product. Utility Model Content

[0004] To address the aforementioned problems, this utility model aims to provide a reliable and intelligent sliding-cover alcohol tester with automatic opening and closing.

[0005] To achieve this technical objective, the present invention provides a sliding cover alcohol tester, comprising a sliding cover and a test body. The sliding cover contains two or more sliding plates, and the test body is provided with a sliding groove and an elastic damping mechanism. The sliding plates are embedded in the sliding groove, and the elastic damping mechanism abuts against the sliding plates. The elastic damping mechanism is composed of a fixed frame, a ball-head plunger, an elastic element, and a ball bearing. The ball-head plunger is embedded in the fixed frame, and the elastic element and ball bearing are installed within the ball-head plunger. The ball bearing can partially protrude from one side of the ball-head plunger.

[0006] The upper part of the test body is provided with a detection head with an air inlet groove. A semiconductor alcohol sensor is installed inside the detection head. The sliding cover can cover the detection head. The bottom of the sliding plate is also provided with a limiting protrusion. The sliding groove is provided with a corresponding limiting post. When the sliding cover slides upward and opens, the limiting protrusion can abut against the limiting post to limit the movement.

[0007] Preferably, the sliding plate above the limiting tooth is a flat, sloping structure with gradually decreasing thickness; a metal sliding piece is provided on one side of the sliding plate that abuts against the elastic damping mechanism, and the metal sliding piece abuts against the ball.

[0008] Preferably, the test body is equipped with an MCU and a status detection mechanism. The status detection mechanism and the semiconductor alcohol sensor are electrically connected to the MCU. When the status detection mechanism detects that the sliding cover changes from a closed state to an open state, the status detection mechanism sends a signal to the MCU so that the MCU controls the alcohol tester to enter the power-on state.

[0009] Preferably, the status detection mechanism includes a detection switch and a trigger for controlling the detection switch.

[0010] Preferably, the bottom of the trigger is connected to a telescopic arm. When the sliding cover is closed, the telescopic arm is compressed by the trigger, and the detection switch is in the closed state. The detection switch is provided with an extension rod. When the sliding cover is opened, the telescopic arm resets and pushes open the extension rod of the detection switch, so that the detection switch is opened.

[0011] Preferably, the status detection mechanism includes a proximity sensor disposed inside the sliding cover. When the proximity sensor detects that the sliding cover is closed, it is in a closed state; when the proximity sensor detects that the sliding cover is open, it is in a powered-on state.

[0012] Preferably, the test body also includes a battery and a sound-generating element, and a display screen is also provided on the test body. The semiconductor alcohol sensor, battery, sound-generating element, and display screen are all electrically connected to the MCU.

[0013] Preferably, the bottom of the groove is provided with a groove that matches the limiting protrusion.

[0014] Preferably, the sliding cover is also provided with anti-slip texture on both sides.

[0015] Preferably, the sliding cover has guide rails on both sides, and the detection head has a guide groove on the outside that matches the guide rails.

[0016] The beneficial effects of this utility model are as follows: the use of an elastic damping mechanism in conjunction with a sliding plate provides sliding damping, facilitating the opening and closing of the testing instrument; the metal sliding piece on the side of the sliding plate effectively reduces friction and wear, significantly improving service life; the precise mechanical limiting of the opening position of the sliding cover is achieved through the contact between the limiting protrusion at the bottom of the sliding plate and the limiting post in the sliding groove, preventing excessive sliding and component detachment; the ingenious overall structure ensures the smoothness of the sliding cover's movement and the overall reliability of the product.

Detailed Implementation

[0025] The utility model of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. In order to provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; other embodiments obtained based on the content described in this application without creative effort are all within the scope of protection of this utility model.

[0026] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of clearly describing this embodiment, rather than indicating or implying that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] like Figure 1-7 As shown, the specific embodiment of this utility model is a sliding cover alcohol tester, which mainly consists of two parts: a sliding cover 1 and a test body 2.

[0028] Two symmetrically distributed sliding plates 11 are fixedly installed on the inner side of the sliding cover 1. The bottom of each sliding plate 11 has a hook-shaped limiting protrusion 111. Above the limiting protrusion 111, the sliding plate 11 is designed as a gradually decreasing thickness, sloping flat structure, which makes opening and closing the sliding cover 1 easier. A metal sliding piece 112 is also fixedly embedded on the side of each sliding plate 11 that contacts the test body 2. This metal sliding piece is preferably made of wear-resistant materials such as stainless steel. In actual production, the sliding plate 11 can also be made of metal without the metal sliding piece.

[0029] The test body 2 has grooves 21 that correspond one-to-one with and fit the sliding plate 11. The sliding plate 11 is slidably embedded in the grooves 21. An elastic damping mechanism 22 is installed inside the test body 2. The elastic damping mechanism 22 consists of a fixed frame 221, a ball plunger 222, a spring (as an elastic element 223), and a ball 224. The ball plunger 222 is embedded and fixed on the fixed frame 221. The spring and the ball 224 are housed in the ball plunger 222. Under the elastic force of the spring, a portion of the ball 224 can continuously protrude from the side wall of the ball plunger 222 and tightly abut against the metal sliding piece 112 on the sliding plate 11. This "ball spring" structure provides just the right damping force for the sliding of the cover 1, while the metal sliding piece 112 effectively protects the body of the sliding plate 11 and avoids direct wear of the ball 224.

[0030] A limiting post 211 is provided inside the slide groove 21. When the user pushes the slide cover 1 upward to the fully open position, the limiting protrusion 111 at the bottom of the slide plate 11 abuts against the limiting post 211, thereby preventing the slide cover 1 from sliding further and achieving the upper limit of the open state. In addition, a groove 212 is provided at the bottom of the slide groove 21. This groove 212 can engage with the limiting protrusion 111 when the slide cover is closed, so that the slide cover 1 remains stable in the closed state and is not easy to loosen on its own.

[0031] The upper part of the test body 2 is provided with a detection head 23, which has an air inlet groove 231 and encapsulates the core semiconductor alcohol sensor 29. When the sliding cover 1 is closed, it can completely cover the entire detection head 23, providing protection. To further guide the sliding of the sliding cover 1, guide rails 13 are provided on both sides of the inner wall of the sliding cover 1, while the external part of the detection head 23 of the test body 2 is provided with a precisely matched guide groove 24.

[0032] The test unit 2 contains an MCU (microcontroller unit, not shown in the figure), a battery 25, a detection switch 26, and a sound-generating element 28. A display screen 27 is mounted on its panel, and all these electronic components are electrically connected to the MCU.

[0033] The status detection mechanism of this application uses a detection switch 26, the principle of which is as follows: A trigger element, specifically a push rod 12, is fixedly installed inside the sliding cover 1. When the sliding cover 1 is in the closed state, the end of the push rod 12 abuts against the telescopic arm 261 of the detection switch 26, causing the telescopic arm 261 to deform. At this time, the extension rod 262 inside the detection switch is in the open position, and the power circuit of the entire tester is cut off, and it is in the off state.

[0034] When the user pushes the sliding cover 1 upwards, the push rod 12 moves upwards accordingly, separating from the telescopic arm 261 of the detection switch 26. The telescopic arm 261, having lost pressure, immediately resets due to its own elasticity, and moves the extension rod 262 to the closed position, thereby turning on the detection switch 26 and powering on the tester.

[0035] As another preferred implementation, the status detection mechanism can employ a proximity sensor (not shown in the figure). When the proximity sensor detects the sliding cover is closed, it is in the closed state; when it detects the sliding cover is open, it is in the powered-on state. The sensor sends a signal to the MCU, which then controls the tester to power on. This non-contact detection method completely avoids mechanical wear, resulting in a longer lifespan. The entire process is intelligent, the equipment is easy to use, and provides a good user experience. The proximity sensor can be a photoelectric or magnetic sensor, which can replace contact detection methods such as limit switches, detecting the position of the sliding cover and emitting an electrical signal without contact. Specifically, it can be a Hall sensor or an infrared sensor.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present utility model should be included within the protection scope of the technical solution of the present utility model.
