Abstract

The utility model relates to a dental wax dissolving tool, particularly an automatic dental wax pen, which comprises a pen point and a pen body. The utility model is characterized in that a liquid outlet cavity of the pen point extending into a hollow cavity of the pen body from one end of the pen body is communicated with the cavity of the pen body; the pen body near the pen point is provided with an electrothermal element. The utility model has the characteristics of automatic, continuous and rapid supply of wax liquid, high work efficiency, self regulation of wax liquid flux and heating temperature as required, convenient use and simple operation.

Description

Automatic tooth section wax pattern pen

This utility model relates to the molten wax instrument of a kind of tooth section, and the dewaxing of particularly a kind of tooth section is scribbled with pen.

In the modern prosthetic dentistry field, skilled worker's wax pattern instrument commonly used is metal wax spatula and electric wax spoon, the former is a pointed metal bar, need during use on alcohol burner or gas burner, to heat, melt wax stone then, and pick certain wax liquid, be coated with and be drawn on the model, as scribble one deck 10 millimeters long, the wax wire of 1 millimeters thick needs to heat tens of times and scribbles tens of times and just can finish.Though and the latter has electricity heating automatically, also need be stained with wax to scribble for several times, and temperature can not modify tone.Make a secondary cast crown bridge or a stent-type removable denture, 40%～60% time waste is arranged in above operation.

It is a kind of easy to use and the automatic tooth section wax pattern pen of wax liquid can be provided continuously fast that the purpose of this utility model is to provide.

The purpose of this utility model is achieved in that a kind of automatic tooth section wax pattern pen, comprise nib, handwriting, its special character is to stretch to nib in the handwriting cavity from handwriting one end, and it goes out sap cavity and is connected with the handwriting cavity, is being provided with heating by on the handwriting of pen tip.

Be provided with bonnet at the handwriting other end relative with nib, bonnet is provided with the through hole that the handwriting cavity can be connected with space outerpace.

Being provided with on the handwriting bonnet can be with all or part of adjustment screw that opens or closes of through hole.

Described heating is connected with regulator.

Be provided with insulated thermal insulating layer in the handwriting outside.

This utility model compared with prior art has following characteristics: can provide wax liquid automatically continuously fast, improve work efficiency greatly.Aperture by adjustment screw change bonnet through hole realizes the adjusting to the wax flow quantity.Heating-up temperature can be regulated as required voluntarily, and is easy to use, simple to operate.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the circuit theory diagrams of this utility model regulator.

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, tooth section wax pattern pen mainly is made up of nib (1), handwriting (2), forward and backward lid (3), (4), heating element heater (5), regulator, insulated thermal insulating layer (6) automatically.Stretch to nib in the handwriting cavity from handwriting one end, it goes out sap cavity and promptly stores up the wax chamber with the handwriting cavity and be connected, be provided with electrical heating elements in handwriting outside by pen tip, be provided with the protecgulum that is threaded with handwriting in the electrical heating elements outside, the lead-out wire of heating element heater (7) is drawn from the handwriting rear end through the insulation thermal insulation layer, is connected with regulator through plug.The other end of handwriting is connected with bonnet, is connected with adjustment screw (8) on the central through hole of bonnet, and both are for being threaded.This central through hole is connected with radial direction through hole (9) on being arranged on bonnet, constitutes the through hole that the handwriting cavity is connected with space outerpace thus, and the aperture of the degree of depth control through hole that screws in by adjustment screw realizes the adjusting to the wax flow velocity.Be provided with the insulated thermal insulating layer that is enclosed within on the handwriting in the outside of handwriting.Regulator mainly is by transformator B, compositions such as relay indicating light L, potentiometer W.It becomes the voltage of 36 volts safety with 220 volts of city's voltage modulations, and is implemented in 12～36 volts of scopes by potentiometer and regulates, thereby realizes the adjusting to heating-up temperature.

During use, if first the use needs and will send into casting wax in the handwriting cavity, energized, heating element heater work, it is with the fusing of the casting wax in the handwriting front end cavity, and nib is heated simultaneously, and wax liquid is normally flowed out from nib, and can regulate the flow velocity and the heating-up temperature of wax liquid by adjusting adjustment screw and potentiometer, wax pattern pen for working can be adjusted to keeping warm mode, even casting wax is in the incipient melting state.

Claims
