Abstract
The invention relates to a waterproof and condensation-resistant instrument which comprises a front shell, a back shell and a connector. The front shell and the back shell are connected in a sealing manner through a front and back shell sealing ring; and the connector is installed in a sealing manner on the back shell through a connector rubber ring. The waterproof and condensation-resistant instrument is characterized in that: a circuit board is embedded in the front shell; an anti-fog coating is arranged on an inner surface of the front shell, wherein the inner surface is directed towards the circuit board; the circuit board is also provided with a light guiding frame; a mask is supported on the light guiding frame; and the back shell is also provided with a waterproof permeable plug. The advantages of the invention are that: in the invention, the waterproof and condensation-resistant requirements of the instrument are realized, and when the temperature drops suddenly, the white water mist is prevented from generating to affect reading of the instrument information.
Description
Technical field
This patent belongs to agricultural machinery instrument technical field, particularly relates to a kind of protected against the effects of immersion anti-condensation instrument.
Background technology
The instrumentation of working under agricultural machinery instrument and other open-air atmospheres, under the environment of direct sunlight in summer, in its table, temperature can reach eight or nine ten degree.Under this temperature, sharply decline as instrument suffers the impact watchcase temperature of rainwater, and now in table air and steam temperature be still the condition of high temperature, thereby in table, air and steam are met coldly, can easily form water smoke at watchcase inner surface, affect reading of the interior data of table.Existing instrument adopts the mode of blow-by instrument to solve problems more, in packing less situation, former steam and the air under the condition of high temperature in instrument is discharged in time.But for agricultural machinery and other equipment that need work under the serious environment of dust, unencapsulated instrument easily causes entering of dust, thereby affects performance and the life-span of instrument.
Summary of the invention
This patent provides a kind of protected against the effects of immersion anti-condensation instrument for solving the technical problem existing in known technology, and this instrument had both realized the requirement of instrument preventing dust immersion, and can prevent temperature decrease again time, producing white water smoke affects meter information and read.
A kind of protected against the effects of immersion anti-condensation instrument, comprises fore shell, back cover and connector, between described fore shell and back cover, is tightly connected by front and rear casing sealing ring, and described connector is arranged on back cover by the sealing of connector cushion rubber, it is characterized in that:
Described fore shell is embedded with circuit board, in described fore shell, is provided with antifogging coating towards the inner surface of circuit board, is also provided with Guiding light support on circuit board, is supported with facial mask on Guiding light support,
On described back cover, be also provided with waterproof and breathable plug.
Advantage and good effect that this patent has are:
Because this patent adopts technique scheme, by the connector cushion rubber on front and rear casing sealing ring and back cover between fore shell and back cover, realize the sealing of instrument, prevent that airborne dust from entering.Install waterproof and breathable plug additional in the bottom of instrument, this waterproof and breathable plug adopts macromolecule membrane to be made simultaneously, and it had both allowed the circulation of gas, and the gas of the higher temperature in instrument and steam are discharged, and can prevent again entering of dust macromolecular particle.At the special anti-fog coating of gauge internal transparent window brushing, this coating can prevent that steam from condensing into white water smoke at instrument transparent window in the time of temperature decrease, avoids affecting meter information and reads.
Accompanying drawing explanation
Fig. 1 is the structural representation of this patent.
In figure: 1, circuit board; 2, Guiding light support; 3, facial mask; 4, antifogging coating; 5, fore shell; 6, back cover; 7, connector cushion rubber; 8, connector; 9, waterproof and breathable plug; 10, front and rear casing sealing ring.
Embodiment
For further understanding innovation and creation content, the Characteristic of this patent, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As shown in Figure 1,
A kind of protected against the effects of immersion anti-condensation instrument, comprises fore shell 5, back cover 6 and connector 8, and fore shell 5 adopts one-body molded, and sectional dimension is greater than back cover 6 sectional dimensions.Between fore shell and back cover, be tightly connected by front and rear casing sealing ring 7, front and rear casing sealing ring 10 produces deformation in the process of installing, sealing upper-lower casing.Connector 8 is arranged on back cover by connector cushion rubber 7 sealing, and fore shell is embedded with circuit board 1, in described fore shell, is provided with antifogging coating towards the inner surface of circuit board, and 4 of antifogging coatings can prevent from fore shell 5, generating when there's a sudden fall in temperature white water smoke.On circuit board, be also provided with Guiding light support, be supported with facial mask on Guiding light support, Guiding light support 2, except being used for guiding light, also can play the effect of dwindling space between facial mask 3 and fore shell 5.On back cover, be also provided with waterproof and breathable plug.9 of waterproof and breathable plugs can play the effect that dustproof and waterproof is ventilative, are beneficial to the diffusion of the interior heat of table and steam.
Although by reference to the accompanying drawings the preferred embodiment of this patent is described above; but this patent is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under the enlightenment of this patent; not departing from the scope situation that this patent aim and claim protect, can also make a lot of forms, within these all belong to the protection range of this patent.
