Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer; to carry out clear, complete description to the technical solution of the utility model below; based on the embodiment in the utility model; those of ordinary skills are resulting all other embodiments under the prerequisite of not making creative work, all belong to the scope that the utility model is protected.
As shown in Figure 1 to Figure 3, the no mercury clinical thermometer that provides among the utility model embodiment comprises body 1 and bulb, 2, and the inside of body 1 in axial direction is formed with pore 11, and the inside of bulb, 2 is formed with cavity 22; One end of body 1 is connected with bulb, 2, and pore 11 links to each other with cavity 22; Also be formed with larynx bubble 12 on the pore 11; Be provided with a stationary point projection 13 in the larynx bubble 12, and form runner 14 between the outer wall of the inwall of larynx bubble 12 and stationary point projection 13; The area of passage of runner 14 is less than the area of passage of pore 11; Be provided with temperature sensing liquid in bulb, 2 and the pore 11.
During use:
Utilize bulb, 2 to contact with human body, thereby sounding expands after making cavity 22 interior temperature sensing liquids be heated, can be entered in the pore 11 by cavity 22 after temperature sensing liquid expands, when entering pore 11, temperature sensing liquid is known from experience the runner 14 that forms by between larynx bubble 12 and the stationary point projection 13; After measuring the temperature end, bulb, 2 disengages with human body, temperature sensing liquid in the cavity 22 no longer is heated, and the temperature sensing liquid when leaving human body in the cavity 22 is known from experience the contraction of catching a cold, this moment, the temperature sensing liquid cognition between bulb, 2 and larynx bubble 12 shrank back in the cavity 22, and be positioned at larynx steep 12 opposite sides temperature sensing liquid since the obstruction of runner 14 can not reflux by sounding, therefore making temperature sensing liquid steep 12 places at larynx disconnects, thereby avoided the liquid level of temperature sensing liquid in pore 11 to fall after rise effectively, thereby guaranteed the accuracy of survey measurements; When only need behind the reading whipping just temperature sensing liquid fall after rise to cavity 22.
It is by being provided with larynx bubble 12 and forming stationary point projection 13 in larynx bubble 12 in pore 11, make temperature sensing liquid reduce through larynx bubble 12 and stationary point 13 o'clock area of passages of projection, thereby make temperature sensing liquid after through larynx bubble 12, can not reflux because of the contraction of temperature sensing liquid self, avoid the liquid level of temperature sensing liquid in pore 11 to fall after rise, thereby guaranteed the accuracy of survey measurements.
Simultaneously, it is provided with stationary point projection 13 then by larynx bubble 12 is set earlier in larynx bubble 12 in pore 11, and the runner 14 that the outer wall that utilizes stationary point projection 13 and the inwall of larynx bubble 12 form changes the area of passage of pores 11, and it is convenient to the manufacturing more.
In the present embodiment, preferably, as shown in Figure 3, the two ends of stationary point projection 13 can radially be extended and be affixed with the inwall of larynx bubble 12 respectively, and form two runners 14 between larynx bubble 12 and stationary point projection 13, and the area of passage sum of two runners 14 is less than the area of passage of pore 11; Further preferred, stationary point projection 13 can be steeped 12 inner wall deformation by larynx and directly be formed, and promptly stationary point projection 13 is structure as a whole with the inwall of larynx bubble 12.
In the present embodiment, its major advantage is that also temperature sensing liquid does not adopt mercury, because mercury is a kind of extremely toxic substance; Its temperature sensing liquid is a quaternary eutectic gallium indium tin zinc liquid alloy.
In the present embodiment,, scale coating 3 can be set on the outer wall of body 1 for the ease of on no mercury clinical thermometer, reading device being set.
In the present embodiment,, can be 6～14.5mm with bulb, 2 length setting in axial direction because no mercury clinical thermometer at different use-patterns, therefore needs bulb, 2 is set to different length for this reason.
Concrete, the no mercury clinical thermometer that the oral cavity is used can be with the length setting of bulb, 2 at 13～14.5mm.
The no mercury clinical thermometer that anus is used can be with the length setting of bulb, 2 at 8.5～9.5mm.
The no mercury clinical thermometer that animal is used can be with the length setting of bulb, 2 at 6～7mm.
In the present embodiment, for the ease of be processed to form stationary point projection 13 in larynx bubble 12, need to guarantee to have certain space in the larynx bubble 12, the distance between middle part two inwalls radially of larynx bubble 12 is 0.8～1.1mm for this reason; Distance between larynx bubble 12 two ends in axial direction is 2.5～3.5mm.
In the present embodiment, in order to make no mercury clinical thermometer when the take temperature, temperature sensing liquid can steep 12 interior stationary point projectioies 13 through larynx bubble 12 and larynx, thereby realize that temperature sensing liquid can not reflux because of the contraction of temperature sensing liquid self after through larynx bubble 12, need certain restriction is made in the position that is provided with of larynx bubble 12 for this reason; Preferably, larynx bubble 12 is 10～12mm near an end of bulb, 2 and the distance between body 1 and bulb, 2 joints; Thereby can guarantee effectively that temperature sensing liquid can steep 12 by larynx when using no mercury clinical thermometer.
In the present embodiment,, can be 105～115mm with body 1 length setting in axial direction because no mercury clinical thermometer at different use-patterns, therefore needs body 1 is set to different length for this reason.
Wherein, the no mercury clinical thermometer that the oral cavity is used can be preferably 115mm with the length setting of body 1 at 110～115mm.
The no mercury clinical thermometer that anus is used can be preferably 110mm with the length setting of body 1 at 105～110mm.
In the present embodiment, body 1 cross section radially can be any in circle or triangle or the polygon.
It should be noted that at last: above embodiment and embodiment only in order to the explanation the technical solution of the utility model, are not intended to limit; Although the utility model is had been described in detail with reference to aforementioned embodiments and embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to aforementioned embodiments or technical scheme that embodiment put down in writing, perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence disengaging the utility model embodiment of appropriate technical solution or the spirit and scope of embodiment technical scheme.
