Description

Device for realizing earmuff ejection through electromagnet

Technical Field

The utility model belongs to the technical field of the technique of earmuff jettison device and specifically relates to a device that realizes earmuff ejection through the electro-magnet.

Background

The infrared thermometer obtains the infrared radiation that human skin surface sent and through internal algorithm human body temperature through utilizing infrared receiving transducer, when using infrared thermometer measurement ear tympanic membrane department's temperature, the probe of infrared thermometer needs the part to stretch into the ear, in order to prevent the cross infection between the surveyed personnel, usually can establish disposable earmuff at the probe overcoat.

The earmuff is disposable article, need frequently to change, earmuff ejection device is that can be convenient will make used earmuff launch away from the probe, current earmuff ejection device all is pure mechanical structure, the earmuff ejection device of this kind of structure needs the user to use great strength to detain and moves ejection button, it is more when the user is detained ejection button in the short time, can make the finger that detains ejection button produce uncomfortable feelings such as ache, user experience is not good, and the outward appearance of product is exquisite inadequately.

Disclosure of Invention

To the not enough of existence among the above-mentioned prior art, the utility model aims to provide a device that realizes earmuff ejection through the electro-magnet.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a device that realizes earmuff ejection through electro-magnet, includes the casing, be provided with the probe on the casing, the cover is equipped with the earmuff on the probe, be provided with control panel and plug-type electro-magnet in the casing, lie in on the casing locate directly over the plug-type electro-magnet fretwork, the slide bar of plug-type electro-magnet is inserted and is located in the fretwork, be provided with on the casing and launch the key, electro-magnet, launch the key all with control panel electric connection.

Furthermore, a plurality of bulges are arranged at the lower end part of the probe, and the earmuffs are tightly bound on the probe through the bulges.

Furthermore, the top of the sliding rod of the push-pull electromagnet is abutted to the edge of the bottom of the ear cap.

Adopt above-mentioned scheme, the beneficial effects of the utility model reside in that: the earmuffs are automatically ejected by the push-pull type electromagnet without manual power ejection, the operation is convenient and fast, fingers are not sore even if ejection is frequently performed, and the use experience of a user is improved; moreover, the ejection key is used for replacing a purely mechanical key, the ejection key can be made very small, and the attractiveness of the product is improved.

Drawings

Fig. 1 is a perspective view of an embodiment of the present invention;

fig. 2 is an exploded view of an embodiment of the present invention;

fig. 3 is a schematic structural diagram of an embodiment of the present invention;

a housing 1; a probe 2; an ear cap 3; a control panel 4; a push-pull electromagnet 5; a slide lever 6; hollowing out 7; an eject key 8; and a protrusion 9.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

As shown in the attached drawings, the device for realizing earmuff ejection through the electromagnet comprises a shell 1, wherein a probe 2 is arranged on the shell 1, an earmuff 3 is sleeved on the probe 2, a control panel 4 and a push-pull electromagnet 5 are arranged in the shell 1, the shell 1 is provided with a hollow part 7 right above the push-pull electromagnet 5, a sliding rod 6 of the push-pull electromagnet 5 is inserted in the hollow part 7, an ejection key 8 is arranged on the shell 1, and the electromagnet 5 and the ejection key 8 are both electrically connected with the control panel 4.

The lower end of the probe 2 is provided with a plurality of bulges 9, and the ear cap 3 is tightly bound on the probe 2 through the bulges 9.

The top of the sliding rod 6 of the push-pull electromagnet 5 is abutted against the bottom edge of the ear cap 3.

The push-pull electromagnet 5 mainly comprises a coil, a sliding rod 6, a static iron core, a power supply, a controller and other accessories, and can realize the linear reciprocating motion of the sliding rod 6 by switching on and off.

When the ear muffs 3 are required to be ejected from the probe 2, the ejection key 8 is pressed, the push-pull type electromagnet 5 is started, the sliding rod 6 slides out of the hollow part 7 to eject the ear muffs 3 on the probe 2, after the ejection key 8 is loosened, the push-pull type electromagnet 5 is closed, the sliding rod 6 resets, and a complete ejection action is completed.

The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
