Abstract
The utility model relates to an electric heater for a stone needle, which is suitable for the heating of the stone needle. A PTC element is embedded in the stone needle. The middle part of the stone needle is processed with an inner groove. Electrodes of a metal sheet are arranged at both side of the PTC element. The middle part of the left side of the stone needle is provided with a thread guide hole communicated with the inner groove. The outer end of the thread guide hole is provided with a socket hole. The utility model is composed of the PTC element arranged at the middle part of the inner groove, the electrodes of the metal sheet at both sides of the PTC element, and a guide line welded on the electrodes of the metal sheet. The utility model has the advantages that the utility model has constant temperature, the utility model can supply heat for a long time, and the therapeutic effect of traditional stone needle thermotherapy is enhanced.
Description
This utility model relates to a kind of electric heater unit of stone needle.
Stone needle is the stone instrument that is used for the treatment of disease ancient times.Stone needle therapy has 16 kinds of Therapeutic Method, and wherein a kind of most popular method is called warming therapy, is about to be put in patient part after stone needle heats or massage.The modern is that stone needle bubble is warm or rest roasting heat on the heating installation in hot water to the common heating means of stone needle, and then act on human body, the shortcoming of this method is that temperature is wayward, the beginning temperature is very high, cause scald easily, and heat scatters and disappears at short notice, is difficult to treat for a long time.
The purpose of this utility model is to provide the electric heater unit of the stone needle of a kind of constant temperature, safety, heat supply for a long time.
As follows for realizing the technical measures that this utility model purpose takes: this utility model is that the PTC element is embedded among the stone needle, process an approximate cuboid by middle part at stone needle, its length is slightly larger than the length of sheet metal electrode, it is wide wide with the sheet metal electrode, its high inside groove, the length of sheet metal electrode and wide diameter sum that is respectively the PTC element of on length and width, being arranged that equates with two sheet metal electrodes and PTC component thickness sum.Boring fairlead from the stone needle left side central portion is communicated with inside groove, bore socket aperture again in the outer end of fairlead, the sheet metal electrode that is placed on the PTC element at inside groove middle part and PTC elements on either side be welded on the lead-in wire on the sheet metal electrode and constitute with the socket of lead-in wire other end welding.The effect of plug is to be used for the opening of shutoff inside groove after having assembled electric heater unit.Adopt isolating transformer that the 220V alternating current is become the low-voltage safety alternating current of 10～30V, socket on stone needle and inner sheet metal electrode are with the PTC element and are electrically connected, and also can use rechargeable battery powered.PTC constant temperature electric heating element is a kind of resistive element of positive temperature coefficient, and energising back temperature raises, and resistance increases simultaneously, causes the reduction of electric current, and temperature is last constant in a fixed numeric values.This utility model adopts the PTC element of 20～25 Ω, and it is constant in 40～50 ℃ to guarantee the stone needle surface temperature with 1 to 4 PTC element parallel connection to look the big I of stone needle.
Advantage of the present utility model is that the thermal conversion efficiency of PTC element is higher, use lower voltage can produce certain heat and temperature, and be a kind of permanent power device basically, promptly be not subjected to the influence of supply voltage current fluctuation, be easy to control so have temperature, temperature constant, the advantage that can treat for a long time.
Fig. 1 is the front cross-section view of a specific embodiment of the present utility model, and Fig. 2 is the vertical view cutaway drawing of Fig. 1.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
This utility model processes an approximate cuboid by stone needle 1 and at the middle part of stone needle 1, its length is slightly larger than the length of sheet metal electrode (2,4), it is wide wide with the sheet metal electrode, it is high equate with two sheet metal electrodes and PTC element 3 thickness sums inside groove 21, the length of sheet metal electrode and the wide diameter sum that is respectively the PTC element of on length and width, being arranged.Be provided with the fairlead 24 that is communicated with inside groove 21 from stone needle 1 left side central portion, in the outer end of fairlead socket aperture 5 is set, the sheet metal electrode (2,4) that is placed on the PTC element 3 at inside groove middle part and PTC elements on either side be welded on the lead-in wire (22,41) on the sheet metal electrode and form with the socket (not shown) of lead-in wire other end welding.The effect of plug 11 is to be used for the opening of shutoff inside groove 21 after having assembled electric heater unit, and the PTC element is the commercially available prod, and the isolating transformer specification is output as 10～30V and exchanges the safety electricity for input 220V exchanges, and power 5～6W is commercially available or customized.
Claims (4)
1. the electric heater unit of a stone needle, it is characterized in that, the PTC element is embedded among the stone needle, by an approximate cuboid that processes at the stone needle middle part, its length is slightly larger than the length of sheet metal electrode, it is wide wide with the sheet metal electrode, its high inside groove that equates with two sheet metal electrodes and PTC component thickness sum, the length of sheet metal electrode and the wide PTC element diameter sum of on length and width, being arranged that is respectively, be provided with the fairlead that is communicated with inside groove in the stone needle left side central portion, outer end at fairlead is provided with socket aperture, the sheet metal electrode that is placed on the PTC element at inside groove middle part and both sides thereof be welded on the lead-in wire on the sheet metal electrode and form with the socket of lead-in wire other end welding.
