Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, technical solution of the present invention will be carried out below
Clear, complete description, based on the specific embodiment in the present invention, those of ordinary skill in the art are not making creativeness
Obtained all other embodiment under the premise of labour belongs to the range that the present invention is protected.
As shown in Figs 1-4, the pressure switch water-inlet-proof structure provided in the present embodiment, including shell 1, the top 13 of shell
For enclosed construction, pressure switch is enclosed in shell 1 together with the side wall 12 of shell, rainwater is stopped to pass through outdoor machine of air-conditioner gap
It splashes in pressure switch, there are the hidden danger of electrical safety for elimination.The bottom of shell 1 is provided with bottom plate 14, offers on bottom plate 14
First through hole 3 passes through to the pipeline for pressure switch, and first through hole 3 is also possible to prevent sending out with pipeline vibration for pressure switch
Life moves radially.Preferably, first through hole 3 and pressure switch pipeline clearance fit.It is provided on the side wall 12 of shell to shell 1
The side wall 12 of the position limiting structure 2 that internal cavities extend, position limiting structure 2 and bottom plate 14 and shell constitutes the sky for accommodating pressure switch
Chamber, position limiting structure 2 prevent pressure switch from moving axially with pipeline vibration with bottom plate 14.Position limiting structure 2 and bottom plate 14 it
Between distance can make pressure switch apparatus between position limiting structure 2 and bottom plate 14 and not move axially to be advisable.It is tied by limit
Structure 2, bottom plate 14 and first through hole 3 can effectively fix pressure switch, to enhance pressure switch water-inlet-proof knot
The reliability of structure.In order to avoid pressure switch line pipe vibration touch pressure Switch main body and pipeline, on the side wall 12 of shell
Open up line outlet of second through-hole 4 as pressure switch line.
Shell 1 is assembled by two case half bodies 11, and case half bodies 11 are enclosed by top surface, bottom surface and side three
Made of with axially open semi-cylindrical shells.The side of two case half bodies 11 forms opening phase by elastic sheet 7
Pair flexible connection locked when two case half bodies 11 are interlocked by having from lock set 8, should to form shell 1
It is separately positioned on two case half bodies 11 from the both ends of lock set 8.
It in the above-described embodiments, include buckle block 81 and buckle mouth 82 from lock set 8, buckle block 81 is disposed therein one
On case half bodies 11, buckle mouth 82 is provided with the corresponding position of another case half bodies 11.
It, can also be in the shell below the second through-hole 4 in order to avoid water is flowed on pressure switch terminal by pressure switch line
Solidus structure 5 is set on the side wall 12 of body, and pressure switch line is fixed on string-passing structure after coming out from the second through-hole 4, is formed back
Water is curved, can effectively avoid water and is flowed on pressure switch terminal by pressure switch line.
Above scheme is advanced optimized, heat release hole 6 is opened up on bottom plate 14, it is anti-because increasing to can effectively avoid pressure switch
Shield measure leads to pressure switch ontology and pressure switch line temperature higher the problem of causing electrical safety.Heat release hole 6 can open up
It individually can also open up multiple, shape is not particularly limited, and can be round hole and/or waist hole etc..

In practical applications, position limiting structure 2 can also be by the screw hole and/or pin hole that are provided on the side wall 12 of the shell and and spiral shell
Bolt that hole and/or pin hole match and/or pin bank at.The setting quantity of position limiting structure 2 can be individually, more preferable in order to reach
Limit effect, may be set to be multiple, multiple position limiting structures 2 are evenly distributed in the circumferential direction of shell 1.
It is above-mentioned to be to the description of position limiting structure 2 be in order to facilitate understanding scheme rather than do particular determination, limited in the present invention
The shape and quantity of bit architecture 2 do not do particular/special requirement, move axially as long as pressure switch can be limited with pipe vibration
.
Pressure switch water-inlet-proof structure provided by the invention effectively solves protection question of drenching with rain existing for existing outdoor machine of air-conditioner,
Improve the waterproof performance of electrical part.The structure prevents the structure by the position limiting structure 2 and first through hole 3 of increase pressure switch
It is loosened because of pipeline vibration, increases the reliability of protection；It is the line outlet of pressure switch line by the second through-hole 4 of setting, avoids
Pressure switch line touch pressure Switch main body and pipeline due to vibration prevent from accidentally touching switch, provide the safety of device；Pass through increasing
Add heat release hole 6, can effectively avoid pressure switch because increase safeguard procedures cause pressure switch ontology and pressure switch line temperature compared with
Height causes the problem of electrical safety；By increasing a solidus structure 5, the fixation of pressure switch line is formed into return trap, it can be effective
Water is avoided to flow on pressure switch terminal by pressure switch line.
The present invention also provides a kind of outdoor machine of air-conditioner, which has above-mentioned pressure switch water-inlet-proof structure.
Finally, it should be noted that embodiment of above and embodiment are merely illustrative of the technical solution of the present invention, rather than it is right
It is limited；Although referring to aforementioned embodiments and embodiment, invention is explained in detail, the ordinary skill of this field
Personnel are it is understood that it can still modify to technical solution documented by aforementioned embodiments or embodiment or right
Part of technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution
