The heater comprises a shell body, wherein a circuit comprising a PTC heating piece, a plug and a timed closing integrated chip is arranged in the shell body. A groove is formed in the upper portion of the shell body, a heat-insulating layer is arranged on the inner wall of the groove, the heat-insulating layer is provided with a metal cylinder, the PTC heating piece is arranged at the bottom of the metal cylinder, a chamber used for holding a mosquito-repellent incense coil is formed in the upper portion of the metal cylinder, the top pf the metal cylinder is provided with an air permeable hole, ventilation holes are formed in the bottom of the shell body, in the bottom of the groove, in the heat-insulating layer and in the metal cylinder to form a channel for flowing of upper airflow and lower airflow, the heating piece is composed of two symmetric square heating piece bodies, and a seam used for air flowing is formed between the two heating piece bodies.
Description
Technical field
The utility model relates to a kind of mosquito-repellent incense heater, especially the heater of electrical heating anti-mosquito incense sheet mode.
Background technology
Summer, mosquito was many, needed to use anti-mosquito incense sheet and supporting heater, and anti-mosquito incense sheet is the special-purpose scraps of paper of a certain amount of mosquito liquid medicine of pre-soaked mistake.But the temperature-sensitive fever tablet of existing structure is generally plank frame, and anti-mosquito incense sheet is placed on the fever tablet top, is unfavorable for like this Air Flow and effectively takes away the medicine that volatilizes, and causes the medicine liquor residue on housing.
Summary of the invention
It is the mosquito-repellent incense heater that improves fever tablet and be conducive to current downflow on air that the utility model provides.
the purpose of this utility model is completed by following technical solution, improve the mosquito-repellent incense heater of heating plate, comprise housing, enclosure interior is provided with and comprises the PTC heating plate, plug, the timed-shutoff closed set becomes the circuit of chip, described housing top is provided with a groove, described groove inwall has thermal insulation layer, place a metallic cylinder on described thermal insulation layer, described PTC heating plate is located at the bottom of described metallic cylinder, the chamber that holds anti-mosquito incense sheet is formed at described metallic cylinder top, described metallic cylinder end face has air-vent, it is characterized in that, described housing bottom, bottom portion of groove, thermal insulation layer and metallic cylinder all have air vent, form the passage of up and down air current flow, and described heating plate is comprised of the square heating plate of two symmetries, form the gap of Air Flow between described two heating plates.
Described heating plate is constant-temperature PTC thermal resistor.
The utility model heating plate forms by two arranged side by side, and forms in addition the gap of Air Flow between two heating plates, so facilitates Air Flow to take away medicine on anti-mosquito incense sheet.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to looking up structural representation;
Fig. 3 is that the PTC heating plate is placed in the structural representation on metallic cylinder.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed introduction:
As shown in Figure 1, 2, 3: improve the mosquito-repellent incense heater of heating plate, comprise housing 1, enclosure interior is provided with and comprises that PTC heating plate 2, plug 3, timed-shutoff closed set become the circuit of chip 4, and heating plate is constant-temperature PTC thermal resistor, and plug directly is fixed on the housing left end.Described housing top is provided with a groove 5, described groove inwall has thermal insulation layer 6, places a metallic cylinder 7 on described thermal insulation layer, and described PTC heating plate is located at the bottom of described metallic cylinder, the chamber that holds anti-mosquito incense sheet 8 is formed at this metallic cylinder top, and the metallic cylinder end face has air-vent 9.Housing bottom, bottom portion of groove, thermal insulation layer and metallic cylinder all have air vent 10 corresponding to up and down, form thus the passage of up and down air current flow, and described heating plate is comprised of the square heating plate of two symmetries, forms the gap of Air Flow between described two heating plates.
Claims (2)
