Abstract
The invention discloses an oil level warning structure of a chain saw, comprising an oil tank and a warning circuit arranged in a casing, wherein the bottom of the oil tank is at least provided with a liquid level sensor for sensing the oil level change in the oil tank and further converting the oil level change into an electric signal; and the liquid level sensor is connected with the warning circuit by a signal wire and leads the warning circuit to be conducted for warning by transmitting the electric signal. In the oil level warning structure of the chain saw, the condition of lack of oil is intuitively expressed to a warning signal so as to lead a user to know directly without opening the oil tank to check, therefore, the oil level warning structure is very time-saving and convenient.
Description
Technical field
The present invention relates to chain saw structure, particularly a kind of oil level warning structure of chain saw.
Background technology
Chain saw relatively general by oil mass, therefore user uses chain saw can deliberately not check in the fuel tank of chain saw whether have enough oil at every turn, therefore also will this thing happens, work finds that chain saw does not have oil not worked midway, have to stop and added oil and continue again, if user's oil for subsequent use, also will first go to buy, certainly will affect user's mood and operating efficiency.
Summary of the invention
Problem to be solved by this invention is just to provide a kind of oil level warning structure of chain saw, simple in structure, easy to make, refuels by warning reminding user in fuel tank oil starvation situation, gets ready in advance, avoids work to interrupt, and affects operating efficiency.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: oil level warning structure of chain saw, comprise fuel tank and be located at the warning circuit in casing, it is characterized in that: be at least provided with oil level in an induction fuel tank in fuel tank bottom and change and then convert to the liquid level sensor of the signal of telecommunication, liquid level sensor is connected with warning circuit by holding wire and makes warning circuit connection warning by sending the signal of telecommunication.
Further, described holding wire is provided with the signaling switch of often opening, and signaling switch is connected in warning circuit.
Further, described liquid level sensor is provided with two, is located at respectively on two diagonal angles of fuel tank bottom surface.
Further, described liquid level sensor is provided with three, and one of them is located in the middle of fuel tank bottom, and two other is located at respectively on two diagonal angles of fuel tank bottom surface.
Further, described liquid level sensor is provided with four, is located at respectively on four corners of fuel tank bottom surface.
Further, described liquid level sensor is provided with five, and one of them is located in the middle of fuel tank bottom, on other four four corners that are located at respectively fuel tank bottom surface.
Further, described fuel tank sidepiece is also provided with liquid level sensor.
Further, on the holding wire of described each liquid level sensor, be equipped with signaling switch, the signaling switch of all liquid level sensors is connected in warning circuit.
Adopt after technique scheme, tool of the present invention has the following advantages: oil starvation situation is expressed to alarm signal intuitively, allow user be directly acquainted with, needn't open fuel tank and check, and can not keep flat and make to judge fuel tank oil starvation by accident after fuel tank inclination because of chain saw.

Detailed description of the invention
The structural representation of an embodiment of the present invention as shown in Figure 1, oil level warning structure of chain saw, comprise fuel tank 1 and be located at the warning circuit in casing, at least be provided with the liquid level sensor 2 that oil level in an induction fuel tank changes and then convert to the signal of telecommunication in fuel tank bottom, liquid level sensor is connected with warning circuit by holding wire and makes warning circuit connection warning by sending the signal of telecommunication.Holding wire is provided with the signaling switch of often opening, and signaling switch is connected in warning circuit.
The potential difference signal of failing while being annihilated current potential that liquid level sensor produces and fluid shortcoming completely by fluid between current potential that complete covering liquid level sensor produces is collected and reports to the police by warning circuit.
In above-described embodiment, in fuel tank bottom, two, three, four or five liquid level sensors can be set, concrete distribution situation is as shown in Fig. 3,4,5 and 6.While being provided with two liquid level sensors, be located at respectively on two diagonal angles of fuel tank bottom surface; While being provided with three liquid level sensors, one of them is located in the middle of fuel tank bottom, and two other is located at respectively on two diagonal angles of fuel tank bottom surface; While being provided with four liquid level sensors, be located at respectively on four corners of fuel tank bottom surface; While being provided with five liquid level sensors, one of them is located in the middle of fuel tank bottom, on other four four corners that are located at respectively fuel tank bottom surface.At fuel tank sidepiece, liquid level sensor also can be set in addition, as shown in Figure 2, on the holding wire of each liquid level sensor, be equipped with signaling switch, the signaling switch of all liquid level sensors is connected in warning circuit, as shown in Figure 7, so just can avoid making to judge fuel tank oil starvation by accident after fuel tank inclination because chain saw does not keep flat.When the potential difference signal that only has all liquid level sensors to send reaches the rated value of signaling switch closure, warning circuit just can be connected warning.
Except above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make according to the present invention various changes and distortion, only otherwise depart from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
