Abstract

An electrothermal mosquito dispeller with full-ceramic sealed core is composed of upper and lower electrode plates, PTC thermistor, face shell, lower bottom, ceramic core, ceramic plug, indicator light, resistor and power line. Because the ceramic core piece and the ceramic plug are used for sealing the upper electrode plate and the lower electrode plate which clamp the PTC thermistor, the whole heating assembly is in a full-sealed shape, and the use is safe and reliable. And because the area of the heating surface of the support is increased, the traditional Chinese medicines in the mosquito repellent tablet are volatilized more thoroughly, and the mosquito repelling and killing effect is greatly improved.

Description

Full ceramic seal chipware electric mosquito heater

The utility model relates to a kind of mosquito expelling equipment, particularly a kind of full ceramic seal chipware electric mosquito heater.

In the prior art, similarly the ceramics seat of electric mosquito heater is generally the branch body structure, and supporting heating face all adopts sheet metal.There is following shortcoming in it: 1. structure is compact inadequately, and manufacturing process is trouble; 2. because of supporting heating face adopts sheet metal, so also safety inadequately of use meets accident easily.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of whole ceramic chipware to be hermetically sealed shape, and adopts the full ceramic seal chipware electric mosquito heater of alumina porcelain as supporting heating face.

The purpose of this utility model can be expressed by following measure: the utility model comprises power-on and power-off pole piece, PIC thermosensitive resistor film, face-piece, goes to the bottom, indicator lamp, resistance, power line, it is characterized in that: also have ceramic core, porcelain plug, one square hole is arranged in the ceramic core, accompany the PTC thermosensitive resistor film between the upper and lower electrode slice, and in the square hole in the ceramic core of packing into, upper and lower electrode slice all contacts with the inwall of ceramic core, and there is fraction from ceramic core, to stretch out, the porcelain plug is connected on the aperture, resistance and indicator lamp series connection back is in parallel with the PTC thermosensitive resistor film, is connected on the power supply.Ceramic core adopts the alumina porcelain manufacturing.

Fig. 1 is a structure cutaway view of the present utility model;

Fig. 2 is a profile schematic diagram of the present utility model;

Fig. 3 is circuit theory diagrams of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1, Fig. 2, Fig. 3, the utility model by upper and lower electrode slice 1,4, ceramic core 2, PTC thermosensitive resistor film 3, face-piece 5, go to the bottom 6, porcelain plug 7, indicator lamp 8, resistance 9, power line 10 form.

Have square hole in the ceramic core 2, only need during assembling on request upper and lower electrode slice to be clamped the PTC thermosensitive resistor film, put into square hole and get final product.Upper and lower electrode all contacts with the inwall of ceramic core, and has little part to stretch out outside the ceramic core, with what source of welding current line.Heatproof adhesive seal aperture is used again with the shutoff of porcelain plug in the aperture.Ceramic core adopts the alumina porcelain manufacturing, and tablet is placed directly in ceramic core surface (supporting heating face), and adopts the PTC thermistor as the heater element, make mosquito expelling equipment reach best volatilization temperature, because of contact area increases,, improved repelling effect greatly in addition so make the medicine volatilization of mosquito repellent tablet Central Plains more thorough.

Whole ceramic chipware by go to the bottom 6 and face-piece 5 cooperate fixing, but on the 6 assembly what face-pieces 5 of going to the bottom.In box, also be equipped with resistance and indicator lamp.Resistance is connected back and is connect on the what power supply with indicator lamp, power line 10 is drawn from box.During energising, indicator lamp is shinny, indicating operating status.The PTC thermosensitive resistor film can be adjusted supporting heating surface temperature automatically.

Whole ceramic core 2 is cuboid, and it is block that the PTC thermosensitive resistor film is, and the area and the PTC thermistor electricity of upper and lower electrode slice 1,4 are similar, so that clamp fully, porcelain plug 7 is tetragonal body, is used to stop up the square hole of ceramic core 2.

The utility model has following advantage compared to existing technology:

1. whole ceramic chipware is hermetically sealed shape, and is safe and reliable, and because the heating contact area increases, just medicine volatilization in mosquito repellent tablet Central Plains is more thorough, has greatly improved and has driven effect exterminating mosquito.

2. compact conformation, technology is simple, and is easy to use, is fit to all kinds of occasions of what and drives kill mosquito usefulness.

Claims

1. An all-ceramic sealed core electric heating mosquito repellent, comprising an upper electrode sheet 1, a PIC thermistor sheet 3, a lower electrode sheet 4, a face shell 5, a lower bottom 6, an indicator light 8, a resistor 9, and a power cord 10 , is characterized in that: also have ceramic core 2, porcelain plug 7, there is a side hole in the ceramic core 2, PIC thermistor piece 3 is sandwiched between the upper and lower electrode pieces 1, 4, and the square hole in the ceramic core is packed into In the hole, the upper and lower electrode sheets are in contact with the inner wall of the ceramic core, and a small part protrudes from the ceramic core, and the porcelain plug 7 is connected to the hole.

2. The mosquito repellent according to claim 1, characterized in that: the resistor 9 and the indicator light 8 are connected in parallel with the PIC thermistor 3 after being connected in series, and connected to the power supply.
