Abstract
The invention discloses a minitype water quality detector which comprises a circuit board with a detection head, a battery and a casing, wherein the casing is provided with an avoidance port for avoiding the detection head; and the circuit board is bonded with the peripheral side wall of the avoidance port through glue. Since the circuit board at the detection head is bonded with the peripheral side wall of the avoidance port of the casing through glue, the glue seals and bonds the gap between the circuit board and the casing, thereby preventing water from entering the inside of the casing when the detection head is put in water.

I have designed a kind of miniature Water quality detector, comprise housing, circuit board and battery, and circuit board is provided with for detection of the detection head of water and for showing the display screen of detected value; Housing comprises face-piece and the drain pan being screwed, and circuit board is screwed on face-piece, and installation and removal are convenient in screw fixation, and face-piece end is provided with for dodging the mouth of dodging of detection head.This scheme is unexposed.But there is space detection head and housing junction, when detection head is inserted in water, water easily enters into enclosure interior, thereby affect it, normally works.
Summary of the invention
Technical matters to be solved by this invention be to provide a kind of when detection head is put into water water be difficult for entering the miniature Water quality detector of housing.
The object of the invention is to be achieved through the following technical solutions: a kind of miniature Water quality detector, comprise the circuit board, battery and the housing that are provided with detection head, described housing is provided with for dodging the mouth of dodging of described detection head, and around sidewall is bonding by glue with dodging mouth for described circuit board.
Preferably, described in dodge and mouthful be positioned at described housing one end, the described housing other end is provided with for described circuit board and inserts the placement mouth in described housing, described miniature Water quality detector also comprises the described closing cap of placing mouthful of a sealing.Casing integrated with body arranges, and compares two housings and is fixed together seamlessly, and anti-sealing enters into enclosure interior.
Preferably, described circuit board is provided with for showing display screen and the gauge tap of detected value, and described housing is provided with for dodging the hole of dodging of described display screen; Described miniature Water quality detector also comprises the protective seam of the described display screen of a covering.Hole is dodged in protective seam sealing, not only protect display screen, and anti-sealing or dust etc. enters on display screen.
Preferably, described housing is around provided with for placing the depression of described protective seam in the described hole of dodging.Depression is set and increases the fixing fastness of protective seam.
Preferably, described protective seam is adhesively fixed at described recess by glue.Glue is adhesively fixed firmly, by glue bonding make between housing and protective seam seamless.
Preferably, the height of described depression equals the thickness of described protective seam.Make to keep smooth between housing and protective seam.
Preferably, described housing along described in dodge sidewall mouthful around and be provided with convex edge.Protection detection head in convex edge is set, prevents that detection head is impaired.
Preferably, described convex edge is provided with opening.Being convenient to detection head contacts with water.
Preferably, described miniature Water quality detector also comprises that one is socketed in the lid described housing from described convex edge.While not using, lid is socketed on housing, prevents that detection head is impaired.
Preferably, described housing is provided with a limiting platform, ends at described platform place when described lid is socketed on described housing.The spacing lid of platform is set.
The present invention is because the circuit board at detection head position and housing dodges that mouthful sidewall is bonding by glue around, and glue is bonding the space sealing between circuit board and housing, thereby anti-sealing enters into enclosure interior when detection head is placed in water.
Accompanying drawing explanation
Fig. 1 is the structural representation of the miniature Water quality detector of the embodiment of the present invention;
