Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the present utility model provides a technical solution: the utility model provides an air compressor machine lacks oily protection device, including oil tank body 1, oil tank body 1 one side outer wall bottom fixed mounting has No. two buzzers 4, no. two buzzers 4 below and be located 1 lateral wall of oil tank body on fixed mounting have a spacing post 7 of spheroid on 1 one side inner wall of oil tank, fixed mounting has low-order pressure sensor 8 on the spacing post 7 bottom inner wall of spheroid, fixed mounting has high-order pressure sensor 9 on the spacing post 7 top inner wall of spheroid, be provided with in the spacing post 7 of spheroid and detect floater 10, can carry out spacingly to detecting floater 10 through the spacing post 7 of spheroid that sets up, make it when the fluid position risees, can be accurate touch two pressure sensors, prevent to rock the deviation.

In this embodiment, the inside sealing layer 6 that is provided with of oil tank body 1 is provided with viewing aperture 2 on the oil tank body 1 outer wall, and 2 internally mounted of viewing aperture have explosion-proof toughened glass, and viewing aperture 2 can directly observe the oil tank liquid level, improves performance.

In this embodiment, the oil tank body 1 upper surface has seted up the oiling mouth, and sealing plug 3 is installed to the oiling mouth internal thread to the convenient oiling mouth of opening carries out oiling work.

In this embodiment, a plurality of evenly distributed oil inlet holes 11 are formed in the outer wall of the ball limiting column 7, and the oil inlet holes 11 can enable engine oil to smoothly enter the ball limiting column 7, so that the detection floating ball 10 can float up and down along with the oil level of the engine oil.

In the embodiment, the high-level pressure sensor 9 and the low-level pressure sensor 8 are respectively and electrically connected with a singlechip of the air compressor through wires, and the singlechip is respectively and electrically connected with the second buzzer alarm 4 and the first buzzer alarm 5 through data wires;

the high-position pressure sensor 9 and the low-position pressure sensor 8 can respectively acquire the pressure value of the detection floating ball 10, and simultaneously transmit the pressure value to the singlechip, when the high-position pressure sensor 9 acquires the jacking value when the detection floating ball 10 floats, the singlechip controls the second buzzer alarm 4 to carry out high-liquid-level alarm, and when the low-position pressure sensor 8 acquires the self gravity pressure value of the detection floating ball 10, the first buzzer alarm 5 carries out alarm to remind that the oil in the oil tank is about to be used up.

When the device is used, when a worker performs oiling work through an oiling port, injected engine oil enters the ball limiting column 7 through the oil inlet 11, the detection floating ball 10 floats upwards along with the liquid level of the engine oil during continuous oiling work, when the detection floating ball 10 causes jacking pressure to the high-position pressure sensor 9 by means of buoyancy, the high-position pressure sensor 9 transmits a numerical value to a singlechip of the air compressor, and the singlechip controls the second buzzer alarm 4 to alarm at the moment, so that the numerical value of the liquid level for reminding the external worker of oiling is in a high-position numerical value, and oiling work can be stopped;

in addition, when the consumption of the injected engine oil is reduced, the detection floating ball 10 can be reduced along with the liquid level of the engine oil, when the liquid level of the engine oil is completely reduced below the low-level pressure sensor 8, the detection floating ball 10 integrally falls on the low-level pressure sensor 8, the weight of the detection floating ball 10 is detected by the low-level pressure sensor 8, the value is transmitted to the singlechip of the air compressor, the singlechip controls the first buzzer alarm 5 to alarm, thereby reminding external staff that the oil tank is in an oil shortage state, and the oil tank needs to be refueled,

wherein, the height of low level pressure sensor 8 when using, needs to be higher than oil tank body 1 bottom (specific high numerical value can be adjusted according to different oil tank volume and operation requirement), and the high design effect that high of low level pressure sensor 8 is higher than oil tank body 1 bottom lies in: when the low-level alarm is carried out, a small amount of oil is remained in the oil tank for the air compressor to use, so that the working personnel can be allowed to take and inject engine oil, time conditions are provided for the working of the working personnel before the engine oil is injected, the working personnel is prevented from receiving the alarm again, and the oil in the air compressor is consumed until the working is not completed, so that the air compressor is protected.

According to the utility model, through detecting the cooperation among the floating ball 10, the low-level pressure sensor 8 and the high-level pressure sensor 9, the high-level content and the low-level content of oil can be detected, and simultaneously through cooperation of the second buzzer alarm 4 and the first buzzer alarm 5, when the oil is too low, the first buzzer alarm 5 gives an alarm to buzzing, thereby reminding a worker that the oil in the air compressor is lost and needs to be oiled, and simultaneously when the second buzzer alarm 4 gives an alarm, the outside oiling person can be reminded that the injected oil is sufficient to remind the oiling person to stop oiling work.
