The technical problem solved to make this utility model, technical scheme and beneficial effect are clearly understood, below in conjunction with drawings and Examples, are further elaborated to this utility model.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
Embodiment 1
This utility model is easier to understand for making those skilled in the art, simply simplicity of explanation is carried out to " front end ", " rear end ", when ear thermometer detecting head uses, entering one end of in ear, i.e. its one end having detection mouth is front end, and the other end relative with this front end is rear end; For Fig. 2, Fig. 3, be front end on the left of its paper, right side is rear end.
Cross-sectional schematic shown in decomposing schematic representation and Fig. 2 as shown in Figure 1, this example discloses a kind of ear thermometer detecting head, comprises plastic casing 1, temperature sensor 3, shielding part and holder 5;
The front end of described plastic casing 1 offers detection mouth 12, and inside is formed with cavity 10, and rear end is sealed by described holder 5;
Described shielding part is fixedly mounted in described cavity 10, and described temperature sensor 3 is fixedly mounted in described shielding part.
Wherein, described plastic casing 1 front end is little, rear end is large, its detection mouth 12 place forms interior bag-like structure, place centered by this interior bag-like structure is claimed to form the ring-type front 13 of this detection mouth 12, the front end of this shielding part can be resisted against this ring-type front 13 inwall, and the rear end of its shielding part is then supported by this holder 4, plays fixing effect.
Wherein, described shielding part comprises the housing 2 being positioned at front end and the shielding being positioned at rear end 4;
Some pins 32 that described temperature sensor 3 comprises head 31 and draws from head;
The head 31 of described temperature sensor 3 is fixed in described housing 2, and the head of described temperature sensor 3 is supported in the front end of described shielding 4, and described pin 31 is contained in described shielding 4.
Concrete, above-mentioned housing 2 and shielding 4 is hollow tubular structures, wherein, the head lock chamber 20 of hollow is comprised in above-mentioned housing 2, namely the head 31 of said temperature sensor 3 is fixed in this head lock chamber 20, pin container cavity 40 is provided with in this shielding 4, namely the pin 32 of this temperature sensor 3 is accommodated in described pin container cavity 40, wherein, step 23 is provided with in described head lock chamber 20, the T-shaped structure of head of this temperature sensor, the front end of the structural ledge of its T-shaped 311 is spacing by above-mentioned step 23, the front end of the rear end conductively-closed of its ledge 311 4 is supported, so, whole temperature sensor 3 is fixed in this shielding part.
Wherein, the front end of described housing 2 is provided with the guided wave mouth 22 of reduced diameter, its profile is splayed or tubaeform, adopt the guided wave mouth 22 of this kind of shape, can make visual angle can not be excessively wide, other infrared source is collected receipts by the housing 2 of large quality, further reduces the interference of other infrared source to temperature sensor 3.
Wherein, the material selection metal of described housing 2 and described shielding 4 is made, ferrum, aluminum, copper, nickel etc., and as preferred mode, preferably this housing 2 and shielding 4 is copper material.Copper material is except shield effectiveness is excellent, and its heat conductivility is also more excellent relative to other common metal.
Because this housing is metal material, therefore, its deformability is poor, and water resistance weakens, and for this reason, in this example, is arranged with annular capillary groove 21 at the outer of described housing 3, is provided with overcoat water proof ring a1 in described annular capillary groove 21.This overcoat water proof ring a1 is enclosed in this annular capillary groove 21, and it is placed between the inwall of housing 2 and plastic casing 1, thus possesses excellent water resistance.
As preferred embodiment, in described housing 2, be provided with built-in water proof ring a2, between head 31 front end that described built-in water proof ring a2 is placed in described temperature sensor 3 and the inwall of plastic casing 1.Concrete, described built-in water proof ring a2 detects between ring-type front 13 inwall at mouth 12 place in head 31 front end of temperature sensor 3 and this plastic casing 1.This built-in water proof ring 1b can play the effect of secondary waterproof.Meanwhile, above-mentioned built-in water proof ring 1b and overcoat water proof ring 1a jumps for reduction temperature also has effect.
Wherein, the rear end of described plastic casing 1 is provided with installation portion 11, and described installation portion 11 is riveted with described holder 5, be threaded, clamping or crimp.Here to be threaded to example, be briefly described.Such as be threaded and directly can arrange female thread or external screw thread on installation portion 11, on holder 5, correspondence arranges external screw thread or female thread, holder 5 threaded together is connected on this installation portion 11.Also by the screw added, holder 5 and installation portion 11 all can arrange screw hole, by the cooperation of screw and above-mentioned screw hole, realize being threaded of this installation portion 22 and holder 5.
Its assembling process is described below: loaded by overcoat water proof ring a1 after housing 2 is fixed in annular capillary groove 21; Built-in water proof ring a2 is put into housing 2, then temperature sensor 3 is also loaded in housing 2; Then by above-mentioned temperature sensor 3 and above-mentioned 2 water proof rings have been installed after housing 2 load in this plastic casing 1; Then, will shield 4 and load in plastic casings 1, this temperature sensor 3 is supported in the front end of this shielding 1, temperature sensor 3 is fixed in the shielding part that shielding 4 and housing 2 form; Finally holder 5 is loaded plastic casing 1 rear end, complete assembling process.
The disclosed ear thermometer detecting head of this example, because it has installed this shielding part additional, and its temperature sensor 3 is placed in this shielding part, make its temperature sensor 3 only by the detection mouth 12 induced radiation source of its front end, the approach that other heat radiations are disturbed becomes the process of plastic casing 1-shielding part-air-temperature sensor 3, because this shielding part maskable falls the interference that other infrared sources cause, decrease the impact of other infrared source on temperature sensor 3, reduce the generation that temperature jumps phenomenon.Meanwhile, owing to installing overcoat water proof ring a1 additional in housing 2 outside and installing built-in water proof ring a2 therein additional, its water resistance is also more excellent, meanwhile, can prevent temperature from jumping the generation of phenomenon further.
