The present application claims the priority to Chinese Patent Application No. 201910458573.1 filed on May 29, 2019, which is incorporated herein by reference in its entirety for all purposes.
The present application relates to the field of alcohol detection, and, in particular, to a face-recognizable wall-mounted alcohol detector.
An alcohol detector is an apparatus used for detecting whether alcohol is taken in a human body and how much alcohol is taken in. It can be used as a tool for detecting how much alcohol a driver has drunk for a traffic policeman on duty, so as to effectively reduce the occurrence of significant traffic accidents. An alcohol detector can also be used to detect the level of alcohol in the air expired from a human body on other occasions, for example, at some high-risk firms where it is prohibited to be on duty after drinking, so as to avoid personal casualties and significant property losses.
Conventional alcohol detectors usually comprise an alcohol detecting module and a breathing cup. During use, a subject breathes into the breathing cup with the mouth aiming at the cup, so that the alcohol detecting module can detect the air exhaled by the subject and measure the level of alcohol in the exhaled air.
On some occasions, if there is a large population of subjects, the subjects have to line up and sequentially be subject to the alcohol detector for detection. When the former subject leaves and the next one is tested, the air exhaled by the former remains in the breathing cup, which is not hygienic and will degrade the use experience of the next subject, and the air remained in the breathing cup may interfere with the detection result of the next subject.
In addition, the conventional alcohol detectors comprise an enclosure in which the alcohol detecting module is usually fixed. As a result, when the alcohol detecting module is damaged, it is inconvenient to repair, and sometimes it even causes the alcohol detector to be discarded as a whole, resulting in higher maintenance cost.
In view of the above problems, the present invention provides a face-recognizable wall-mounted alcohol detector, one main object of which is to address the technical problems present in the conventional design of an alcohol detector, that is, unhygiene and inconvenient maintenance when the alcohol detecting module is damaged.
The present application mainly provides the following technical solutions to achieve the above object:

During using the above alcohol detector 100, a subject breathes into the breathing cup 3 via the breathing opening 301, air enters the alcohol detecting module 2 from the air detection inlet 51, and the received air is detected by the alcohol detecting module 2 regarding the level of the alcohol. In particular, the excess air which does not enter the air detection inlet 51 is escaped from the air venting passage 102 via the air vent 302 on the breathing cup 3, so as to prevent air from being remained in the breathing cup 3, improving the use experience of the subject when breathing into the breathing cup 3.
It is to be noted that, the above alcohol detector 100 can be breathed into by a plurality of breathing manners. For example, a subject can directly breathe into the breathing cup 3 with the mouth aiming the breathing cup 3, or can breathe into the breathing cup 3 via an air tube by inserting one end of the air tube into the breathing cup 3. When a subject breathes into the breathing cup 3 by using an air tube, the air tube can be a straw or a disposal air tube used by the subject himself when drinking a beverage, so as to be cleaner and more hygienic.
As shown in
By adopting the above configuration, the connection opening 101 on the enclosure 1 acts as a position-dodging opening, that is, when one end of the breathing cup 3 is inserted into the recess 211 on the case 21, the air mouthpiece 5 in the recess 211 is inserted into the air outlet 304 on the breathing cup 3, so that the parts of both the breathing cup 3 and the alcohol detecting module 2 are inserted into the inside of one another, ensuring a better connection therebetween and thus avoiding loosening.
In a particular application example, the above case 21 can be formed by snap connecting two half cases followed by fixing with a screw. On some occasions, the two half cases can be called as the half top case and the half bottom case, respectively. The above recess 211 is formed by combining the half recess on the half top case and the half recess on the half bottom case.

In the above example, dividing the enclosure 1 into the first half enclosure body 11 and the second half enclosure body 12 provides the effect of convenient processing and assembling.
Further, as shown in
In the above example, since the connecting tube 8 is integrally formed on the enclosure 1, the connection therebetween has a better stability. In addition, since the connecting tube 8 extends through the side wall of the enclosure 1, the air remained in the breathing cup 3 can be guided out from the side, so as to avoid flowing back onto the face of a subject and degrading the use experience of the subject.
Further, as shown in
By adopting the above configuration, the limiting plate 111 can, on one hand, limit the position of the alcohol detecting module 2, and, on the other hand, serve the function of a reinforcement rib, improving the structural strength of the first half enclosure body 11. In addition, in comparison with providing a limiting groove or the like on the first half enclosure body 11, the limiting plate 11 occupies smaller volume, and only a few limiting plates 11 can achieve the function of limiting position of the case 21 of the alcohol detecting module 2, thereby providing the effect of simplifying the structure of the first half enclosure body 11 and reducing the processing cost.
As shown in
It is to be noted here that, the particular form of the chamfer 1111 is not limited, for example, it can be a rounded angle or oblique angle. Preferably, the chamfer 1111 is an oblique angle, so that the case 21 of the alcohol detecting module 2 can be quickly inserted into the first portion of the receiving chamber.
In order to fix the alcohol detecting module 2, a female socket 213 can be provided on the case 21 of the alcohol detecting module 2, and a male plug 112 can be provided on the inside of the first half enclosure body 11. When the alcohol detecting module 2 is inserted into the enclosure 1, the male plug 112 is inserted into the female socket 213. In a particular application example, the male plug can be PCB male plug, and, correspondingly, the female socket can be a PCB female socket.
Further, as shown in
The convex ribs 122 can have a number of 2 or more, and can be sequentially provided at intervals, so as to facilitate the assembling and limiting of the alcohol detecting module 2.
Further, as shown in
In a particular application example, the cover body 4 can be snap connected at the dock interface 121, and connected to the second half enclosure body 12 via a screw, so as to facilitate the removing of the cover body 4 and more stable covering of the cover body 4.
As shown in
As shown in
As shown in
The mounting hole can be formed by snap fitting the first half hole on the first half enclosure body 11 with the second half hole on the second half enclosure body 12. In one particular application example, the transparent piece 6 can assume a long strip shape, and be provided on top of the enclosure 1.
It is to be noted that, in the absence of conflict, the relevant technical features in the above examples can be combined with each other by those skilled in the art depending on actual needs, so as to achieve corresponding technical effects, the particular combinations of which are not provided here in details.
