Abstract
The utility model discloses an oil quantity alarming structure for a chain saw. The oil quantity alarming structure for the chain saw comprises an oil tank, and an alarm circuit which is arranged in a shell, wherein at least one liquid level sensor which senses liquid level change of oil in the oil tank and converts the liquid level change into an electrical signal is arranged at the bottom of the oil tank; and the liquid level sensor is connected with the alarm circuit through a signal wire and is communicated with the alarm circuit to make an alarm by sending the electrical signal. The oil quantity alarming structure for the chain saw expresses an oil-lacking condition into an alarm signal vividly, so that a user can know the oil-lacking condition directly without opening the oil tank to check the oil-lacking condition, thereby being time-saving and convenient.
Description
Technical field
The utility model relates to the chain saw structure, particularly a kind of chain saw oil mass warning structure.
Background technology
Chain saw general relatively with oil mass, therefore the user uses chain saw can not check painstakingly in the fuel tank of chain saw whether enough oil is arranged at every turn, therefore also will this thing happens, work finds that midway chain saw does not have oil not worked, have to stop and added oil and continue again, if the standby oil of user also will go earlier to buy, certainly will influence user's mood and work efficiency.
The utility model content
Problem to be solved in the utility model just provides a kind of chain saw oil mass warning structure, and is simple in structure, easy to make, refuels by warning reminding user under fuel tank oil starvation situation, gets ready in advance, avoids work to interrupt, and influences work efficiency.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: chain saw oil mass warning structure, comprise fuel tank and the warning circuit that is located in the casing, it is characterized in that: be provided with the liquid level sensor that oil level in the induction fuel tank changes and then convert to electric signal at least in fuel tank bottom, liquid level sensor is connected with warning circuit by signal wire and makes warning circuit connection warning by sending electric signal.
Further, described signal wire is provided with the signaling switch of often opening, and signaling switch is connected in the 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 the 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 the fuel tank bottom, on other four four corners that are located at the fuel tank bottom surface respectively.
Further, described fuel tank sidepiece also is provided with liquid level sensor.
Further, be equipped with signaling switch on the signal wire of described each liquid level sensor, the signaling switch of all liquid level sensors is connected in the warning circuit.
After adopting technique scheme, the utlity model has following advantage: the oil starvation situation is expressed alerting signal intuitively, allow the user be directly acquainted with, needn't open fuel tank and check, and can not keep flat and make the fuel tank back erroneous judgement fuel tank oil starvation that tilts because of chain saw.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 6 is the distribution schematic diagrams of five liquid level sensors in the fuel tank bottom;
Fig. 7 is provided with four warning circuit figure behind the liquid level sensor.
Embodiment
The structural representation of a kind of embodiment of the utility model as shown in Figure 1, chain saw oil mass warning structure, comprise fuel tank 1 and the warning circuit that is located in the casing, at least be provided with the liquid level sensor 2 that oil level in the induction fuel tank changes and then convert to electric signal in fuel tank bottom, liquid level sensor is connected with warning circuit by signal wire and makes warning circuit connection warning by sending electric signal.Signal wire is provided with the signaling switch of often opening, and signaling switch is connected in the warning circuit.
Failing potential difference signal between the current potential that complete covering liquid level sensor produced when being annihilated current potential that liquid level sensor produced and fluid shortcoming fully by fluid is collected by warning circuit and reports to the police.
In the foregoing description, in the fuel tank bottom two, three, four or five liquid level sensors can be set, concrete distribution situation is shown in Fig. 3,4,5 and 6.When being provided with two liquid level sensors, be located at respectively on two diagonal angles of fuel tank bottom surface; When being provided with three liquid level sensors, one of them is located in the middle of the fuel tank bottom, and two other is located at respectively on two diagonal angles of fuel tank bottom surface; When being provided with four liquid level sensors, be located at respectively on four corners of fuel tank bottom surface; When being provided with five liquid level sensors, one of them is located in the middle of the fuel tank bottom, on other four four corners that are located at the fuel tank bottom surface respectively.Also liquid level sensor can be set at the fuel tank sidepiece in addition, as shown in Figure 2, be equipped with signaling switch on the signal wire of each liquid level sensor, the signaling switch of all liquid level sensors is connected in the warning circuit, as shown in Figure 7, so just can avoid not making fuel tank inclination back erroneous judgement fuel tank oil starvation because chain saw keeps flat.When the potential difference signal that has only all liquid level sensors to send reached the ratings of signaling switch closure, warning circuit just can be connected warning.
Except that above preferred embodiment, the utility model also has other embodiment, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
