Abstract

The utility model discloses a tongue depressor with a lighting device, which comprises a wood chip, a handle and a light-emitting device, wherein the light-emitting device is mainly composed of an LED, a fixed support, a spring sheet switch and a power supply; the outer end of the fixed support is provided with an inserting slot in which the wood chip can be inserted and a light ray guide hole. Because the utility model is added with a light source which can project light rays into a mouth cavity, the light source can make the light irradiation in the mouth cavity strong and is favorable for the observation of users. Because the utility model conveniently and integrally combines the wood chip and the handle with the light source, the user can operate the utility model by one hand in use and the operation is convenient.

Description

Spatula with illuminator

Technical field

This utility model relates to a kind of medical appliance, relates to a kind of spatula with illuminator.

Background technology

Employed clinically at present spatula mostly is a bamboo plate greatly.Need to take on the other hand spatula during use, another hands takes torch as light illumination, and it is very inconvenient to operate, and by very weak according to position light, sight line is relatively poor, is unfavorable for observing oral condition.

The utility model content

The purpose of this utility model is to provide the spatula that a kind of user is easy to operate, observation more clearly has illuminator.

For achieving the above object, technical solution of the present utility model is:

This utility model is a kind of spatula with illuminator, and it comprises wood chip, handle, light-emitting device.Described light-emitting device mainly is made up of LED, fixed support, elastic sheet switch and power supply, and described support bracket fastened outer end is provided with one and can holds and receive slot and the light guide hole that wood chip inserts, and described LED is installed on the fixed support and towards the light guide hole; Described LED, elastic sheet switch and power supply are electrically connected; Described fixed support, LED, elastic sheet switch and power supply are installed in the handle hollow cavity.

Described elastic sheet switch is made up of first switch shrapnel, shell fragment fixed mount and second switch shell fragment, first switch shrapnel is fixed on the shell fragment fixed mount, its middle part forms a bending part, this bending part stretches into slot and is positioned on the running orbit of wood chip insertion, the second switch shell fragment is installed in the first switch shrapnel opposite face, forms Elastic Contact with first switch shrapnel.

It also comprises a self-lock switch, and this self-lock switch is in parallel with elastic sheet switch and be installed in the handle, and the button on it passes in the handle cinclides; Self-lock switch is electrically connected with LED, power supply.

After adopting such scheme, because this utility model has increased by one can be with the intraoral light source of ray cast, this light source can make in the oral cavity illumination stronger, being beneficial to user observes, and owing to this utility model is combined into one wood chip and the handle with light source easily, during use, the user one-hand operation, it is very convenient to operate.

Below in conjunction with the drawings and specific embodiments this utility model is further described.

The specific embodiment

Shown in Figure 1A, 1B, this utility model is a kind of spatula with illuminator, and it comprises wood chip 1, handle 2 and light-emitting device 3.

Shown in Fig. 2 A, 2B, described handle 2 is made up of loam cake 21, lower cover 22 and battery case 23, and loam cake 21 can fasten mutually with lower cover 22, forms a cavity.Described battery case 23 is arranged on the rear portion of loam cake 21, and is one-body molded with loam cake 21, and its peristome fastens a battery cover 24.

Described light-emitting device 3 is made up of LED31, fixed support 32, elastic sheet switch 33, self-lock switch 34 and power supply 35.LED31, elastic sheet switch 33, self-lock switch 34 and power supply 35 are electrically connected (as shown in Figure 4), and elastic sheet switch 33, self-lock switch 34 can be controlled the break-make of LED31 power supply respectively.

The outer end of described fixed support 32 is provided with one and can holds and receive slot 321 and the light guide hole 322 that wood chip 1 inserts.Described elastic sheet switch 33 is made up of first switch shrapnel 331, shell fragment fixed mount 332 and second switch shell fragment 333, first switch shrapnel 331 is fixed on the shell fragment fixed mount 332, its middle part forms a bending part 3311 (as shown in Figure 3), this bending part 3311 stretches into slot 321 and is positioned at wood chip 1 and inserts on the running orbit of slot 321, second switch shell fragment 333 is installed in first switch shrapnel, 331 opposite faces, when wood chip 1 inserts in the slot 321, the second switch shell fragment 333 and first switch shrapnel 331 form Elastic Contact, turn-on power.Described LED31 is installed on the fixed support 32 and towards light guide hole 322; Described fixed support 32 is installed in handle 2 hollow cavities together with affixed LED31, elastic sheet switch 33, self-lock switch 34 and power supply 35 on it.Described self-lock switch 34 is in parallel with elastic sheet switch 33, and the button 341 on it passes in handle 2 cinclides 211 (shown in Fig. 2 B), so that push self-lock switch 34.

Operation principle of the present utility model (as shown in Figure 4):

When the slot 321 on the wood chip 1 insertion fixed support 32 (as shown in Figure 3), first switch shrapnel, 331 bending parts 3311 of elastic sheet switch 33 are by jack-up, first switch shrapnel 331 forms with second switch shell fragment 333 and contacts, turn-on power, LED31 sends light, light penetrates from the light guide hole 322 on the fixed support 32, illuminates the oral cavity.When the slot 321 of wood chip 1 from fixed support 32 extracted out, first switch shrapnel 331 broke away from second switch shell fragment 333, and power supply disconnects.

When wood chip 1 did not insert slot 321 on the fixed support 32, user also can be pushed the button 341 on the self-lock switch 34, with power turn-on, uses as luminaire.
