Detailed Description
Other advantages and effects of the present utility model will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present utility model with reference to specific examples. The utility model may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present utility model.
Reference is made to the accompanying drawings. It should be noted that, the illustrations provided in the present embodiment merely illustrate the basic concept of the present utility model by way of illustration, and only the components related to the present utility model are shown in the drawings and are not drawn according to the number, shape and size of the components in actual implementation, and the form, number and proportion of each component in actual implementation may be arbitrarily changed, and the layout of the components may be more complex. Unless otherwise indicated, terms such as "upper", "lower", "left", "right", and the like, as used herein, refer to the perspective of the viewer of the drawings.
The atomizing device comprises core components such as a liquid storage bin, an atomizing core and the like, and is used for forming complete atomizing equipment after being assembled with a battery rod. The battery rod generally refers to other parts of the atomizing equipment except the atomizing device, and one of the functions is to provide power for the atomizing device after being assembled with the atomizing device. Since the battery pole is not an innovation of the solution of the present utility model, the present utility model does not describe the structure of the battery pole.
Referring first to fig. 1, fig. 1 is a perspective view of an embodiment of a flow rate detection device according to the present utility model. The reference numeral 1 on the cover indicates an oil filling port, and the reference numeral 2 indicates a display device, in this example, a liquid crystal display, and in other embodiments, a pointer counter or the like may be used. The battery and the flow rate detection system and the battery are packaged in the shell 3. Preferably, the present embodiment further comprises a transition 4.
The structure of the present utility model will be described in detail with reference to fig. 2. Fig. 2 is an exploded view of the embodiment of fig. 1. Reference numeral 5 denotes a turbine flow meter, which is the core of the flow detection system. One end of the mark 5, which is close to the oil filling port, is a liquid inlet, and the other end is a liquid outlet, and is communicated with the filter 4. To increase the suitability of the flow sensing device, the present embodiment also provides a transition ring 6. The transition ring 6 is located between the filter 4 and the flowmeter 5, and is used for enhancing the adaptability of the filter 4 and the flowmeter, and different transition rings can be selected for different flowmeters and filters.
The aforementioned flow sensing system includes a circuit board and processor in addition to the turbine flow meter, which are matched thereto. The battery, circuit board and processor are in this case enclosed in a module 51. However, this is not a limitation of the present utility model, and the packaging of the circuit, battery and processor is prior art and is very flexible in location, and can be placed under the cover or anywhere in the housing, without affecting the use.
In use, the flow detection device of the present utility model is mounted on a tank filler line, such as at a tank inlet. When the oil gun refuels to the oil tank, gasoline enters from the oil filling port, the impeller in the turbine flowmeter 5 is driven to rotate, the rotation speed of the impeller is proportional to the flow of the added gasoline, and according to the rotation number of the impeller, the processor can convert the rotation speed of the impeller into the reading of the added measurement and display the reading on the liquid crystal screen 2, so that the detection of the added measurement is realized.
In order to increase the usability, the cover body of the flow rate detection device of the present utility model is designed as shown in fig. 2: the circular upper plane and the circular edge are provided with flanges. The structure is arranged according to the inlet structure of the fuel tank which is more common in the market at present, most of the prior automobile fuel tanks are provided with a transition network mounting structure which can be matched with the cover switch of the utility model, so that the prior automobile fuel tanks can be provided with the flow detection device of the utility model without any modification, and the upper surface is arranged into a plane so as not to influence the closing of the fuel tank cover after the mounting.
More preferably, a push switch (not shown) is further arranged on the cover body, and when the push switch is pressed down, the reading of the flowmeter is automatically cleared, so that preparation is made for flow detection in the next refueling process, and manual clearing before refueling is avoided.
More preferably, the push switch can also be designed as a switch of the entire control circuit, which is disconnected when pressed, on the one hand more power-saving and on the other hand safer.
In conclusion, the flow detection device for the oil tank is simple and convenient to install and low in cost, is matched with the oil quantity meter of the oil gun of the gas station, can avoid the waste of productivity caused by the failure of the flowmeter of the oil gun of the oil station, and can also enable a user to conveniently monitor the oil filling quantity.
The above embodiments are merely illustrative of the principles of the present utility model and its effectiveness, and are not intended to limit the utility model. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the utility model. For example, the turbine flow meter of the embodiments is not required and may be replaced with other liquid flow meters, such as vortex shedding flow meters. Accordingly, only the oil level scaling logic of the processor need be changed, but no structural changes need be made, without departing from the scope of the present utility model. Accordingly, it is intended that all equivalent modifications and variations of the utility model be covered by the claims, which are within the ordinary skill of the art, be within the spirit and scope of the present disclosure.
