Abstract
The invention relates to a novel electric fan capable of adjusting wind speed automatically. The electric fan comprises a fan head, a supporting rod, a base, a switch, a deodorization box, a negative temperature coefficient thermistor and a safety resistor. The electric fan is characterized in that the fan head is connected with the base through the supporting rod, the switch is arranged on the supporting rod, the deodorization box is arranged on the fan head, people can place deodorant in the deodorization box, accordingly, when peculiar smell is generated in air in summer, the deodorant can be placed in the deodorization box, in addition, the negative temperature coefficient thermistor and the safety resistor are connected in series in a circuit, the safety resistor is used for protecting the safety of the whole circuit, when temperature rises, the resistance of the negative temperature coefficient thermistor is lowered, the current of the whole circuit is increased, the rotating speed of a fan blade in the fan head is increased therewith, when temperature falls, the resistance of the negative temperature coefficient thermistor is increased, the current of the whole circuit is decreased, the rotating speed of the fan blade in the fan head is decreased therewith, and the novel electric fan is simple in structure and easy to manufacture.
Description
Technical field
The present invention relates to a kind of electric fan, more precisely a kind of electric fan that can automatically regulate wind speed size.
Background technique
Electric fan is the part that present people often use in daily life, people can use electric fan to obtain in the time of summer nice and cool, in the time of due to summer, weather is often very hot, people are difficult to concentrate one's energy in working and learning under the weather conditions of this sweltering heat, if excess Temperature also easily causes the appearance of the bad physical conditions such as heatstroke, in this case, people tend to use fan to oneself cooling, in the situation that temperature is higher, it is not quite fresh that indoor air often also becomes, sometimes indoor some peculiar smell that also have, so also can affect the normal working and learning of people, in addition, when sleeping evening, people also can hold electric fan, due to the reduction that evening, temperature can be gradually, if people are easy to catch a cold once heading straight for electric fan sleep evening.
For solving the problems of the technologies described above, necessaryly provide a kind of electric fan that can automatically regulate wind speed size, to overcome described defect of the prior art.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of electric fan that can automatically regulate wind speed size a kind of simple in structure, easy to use.
For achieving the above object, the present invention realizes in the following manner:
A kind of electric fan that can automatically regulate wind speed size, comprise fan head (1), strut (2), base (3) and switch (4), it is characterized in that being provided with Deodorised box (5) on fan head (1), in the circuit of whole electric fan, be in series with negative tempperature coefficient thermistor (6) and insurance resistance (7).
The present invention compared with prior art has the following advantages: owing to adopting, Deodorised box be set on electric fan, remove indoor peculiar smell in the time of so just can being convenient for people to summer working and learning; Owing to adopting, in the circuit of electric fan, negative tempperature coefficient thermistor is set, so just can plays the effect of automatic adjusting electric fan wind speed size, when avoiding people to sleep evening, because the wind speed of electric fan is too fast, catch a cold; Owing to adopting, insurance resistance is set in the circuit of electric fan, so just can protects the safety of whole circuit.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
In figure: 1, fan head; 2, strut; 3, base; 4, switch; 5, Deodorised box; 6, negative tempperature coefficient thermistor; 7, insurance resistance.
Embodiment
As follows with reference to accompanying drawing 1:
A kind of electric fan that can automatically regulate wind speed size, comprise fan 1, strut 2, base 3, switch 4, Deodorised box 5, negative tempperature coefficient thermistor 6 and insurance resistance 7, it is characterized in that fan 1 is connecting base 3 by strut 2, on strut 2, be provided with switch 4, on fan 1, be provided with Deodorised box 5, people can be at the interior placement deodouring agent of Deodorised box 5, if summer, indoor air occurred that peculiar smell just can be to the interior placement deodouring agent of Deodorised box 5 like this, in addition, in circuit, be in series with negative tempperature coefficient thermistor 6 and insurance resistance 7, insurance resistance 7 is for the protection of the safety of whole circuit, when temperature raises, the resistance of negative tempperature coefficient thermistor 6 can reduce, it is large that electric current in whole circuit becomes, the rotating speed of a fan 1 interior flabellum also accelerates thereupon, when temperature reduces, the resistance of negative tempperature coefficient thermistor 6 can increase, electric current in whole circuit diminishes, the rotating speed of a fan 1 interior flabellum is also thereupon slack-off, the present invention is simple in structure, be easy to manufacture.
Above embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
Claims (1)
1. the electric fan that can automatically regulate wind speed size, comprise fan head (1), strut (2), base (3) and switch (4), it is characterized in that being provided with Deodorised box (5) on fan head (1), in the circuit of whole electric fan, be in series with negative tempperature coefficient thermistor (6) and insurance resistance (7).
