Description

Technical Field

[0001] The utility model relates to the technical field of fuel stoves, in particular to an adjustable oil supply transfer mechanism for a fuel stove oil supply system. Background Art

[0002] Fuel stoves are generally kitchen utensils used in places such as hotels and restaurants. They use new energy fuels different from traditional fuels such as diesel, ethanol, and gasoline and refined from industrial waste oil, heavy oil, and alcohol oil as fuels, which are more environmentally friendly and energy-saving, smokeless, odorless, health-promoting, and low-emission. The environmental protection quality far exceeds that of traditional kitchen gasoline and diesel fuels, and the energy consumption can be saved by about 40%.

[0003] Fuel stoves are directly connected to the fuel stoves at the user end and the oil storage tank through a liquid extraction pump and corresponding oil guide pipelines. Fuel stoves are selected and equipped with liquid extraction pumps with corresponding powers according to the needs of the application scenarios. Traditional fuel stoves use the form of directly supplying liquid by a liquid extraction pump. However, the fuel stoves at the user end have different requirements for the size of the firepower, that is, the fuel consumption. If the direct supply by the liquid extraction pump is adopted, the power of the liquid extraction pump can meet slightly greater than the demand, but it cannot exceed the demand significantly. If the power of the liquid extraction pump is too high, when the stove is in a state of turning down the firepower or temporarily shutting down, it is easy to cause overpressure damage to the liquid extraction pump and too high oil pressure in the liquid guide pipeline, resulting in an increase in leakage points and potential safety hazards. Therefore, fuel stoves need to be selected and equipped with liquid extraction pumps with corresponding powers according to the needs of the application scenarios, which leads to poor adaptability of fuel stoves. Users need to purchase fuel stoves equipped with liquid extraction pumps with different powers according to different needs, and the equipment cost increases significantly.

[0004] Therefore, on the basis of ensuring the normal use of fuel stoves, the research purpose of the present utility model is to design an adjustable oil supply transfer mechanism for a fuel stove oil supply system that can connect the user end and the oil supply end to form flow regulation and does not require adjusting the power of the liquid extraction pump to improve the adaptability of fuel stoves. Content of the Utility Model

[0005] In view of the above technical problems existing in the prior art, the present utility model provides an adjustable oil supply transfer mechanism for a fuel stove oil supply system, which can effectively solve the above technical problems existing in the prior art.

[0006] The technical solution of the present utility model is as follows:

[0007] An adjustable oil supply transfer mechanism for a fuel stove oil supply system, comprising:

[0008] A liquid inlet mechanism, including an external oil storage container, and a liquid extraction pump is connected and arranged on the oil storage container through a corresponding oil guide pipe;

[0009] The connection mechanism includes a temporary storage container connected to the liquid outlet of the liquid pumping pump. The liquid outlet of the liquid pumping pump is arranged at the upper part of the temporary storage container, and the lower part of the temporary storage container is communicated with a liquid discharge port through a corresponding regulating valve. The liquid discharge port is externally connected to a fuel stove. A corresponding trigger switch is installed at the upper part inside the temporary storage container;

[0010] The electrical connection mechanism. The trigger switch and the liquid pumping pump are respectively electrically connected to the electrical connection mechanism, and the trigger switch and the liquid pumping pump are connected through an electrical connection method; when the liquid pumping pump is in an electrically connected state, as the liquid level in the temporary storage container rises until the trigger switch is triggered, the liquid pumping pump is turned off; when the liquid level in the temporary storage container drops to the position where the trigger switch is disconnected, the liquid pumping pump restarts.

[0011] The transfer mechanism further includes a triggering mechanism for triggering the trigger switch. The triggering mechanism includes a floating ball that rises and falls with the liquid level and a limiting cylinder sleeved outside the floating ball. The limiting cylinder is vertically and fixedly installed in the temporary storage container, and a plurality of liquid permeable holes communicating with the temporary storage container are spaced apart on the side of its bottom.

[0012] The diameter D of the floating ball is smaller than the width of the limiting cylinder.

[0013] A plurality of clamping blocks are spaced apart and protrude upward from the top of the limiting cylinder. A corresponding fixing part is detachably installed at the top of the limiting cylinder in the temporary storage container. Corresponding slot holes are provided on the fixing part for the corresponding clamping blocks. The limiting cylinder is fixedly installed in the temporary storage container by inserting the clamping blocks into the corresponding slot holes.

[0014] The fixing part includes a fixing portion provided with slot holes and a plurality of connecting portions integrally formed and spaced around the fixing portion. The ends of the connecting portions are turned upward and fit with the inner side wall of the temporary storage container and are locked by bolts. The trigger switch is installed on the fixing portion of the fixing part, and its trigger key is arranged below the fixing part.

[0015] An overflow hole communicating with the inside and outside is provided on the side wall of the temporary storage container. The overflow hole is communicated with the oil storage container through a corresponding return pipe. Both the overflow hole and the liquid outlet of the liquid pumping pump are arranged below the trigger switch.

[0016] Advantages of the present utility model:

[0017] 1) The utility model connects the user - end fuel stove and the liquid - pumping pump at the oil - supply end to form a transfer end for fuel - flow regulation. By equipping a liquid - pumping pump with a larger fire - power specification than required and through the intervention of the transfer mechanism of the utility model, the flow rate of the oil supply can be directly adjusted at the transfer end without adjusting the power of the liquid - pumping pump, so as to improve the adaptability of the fuel stove, effectively avoid the leakage - point problem caused by over - pressure when the user - end is in the state of reducing the fire power or temporarily closing, further ensure the use safety and improve the practical effect.

[0018] 2) When the fuel stove installed with the utility model is in use, the liquid - pumping pump starts to pump fuel into the temporary storage container. And the regulating valve of the connection mechanism can be adjusted according to requirements. Moreover, the liquid - pumping pump does not need to be adjusted and ensures that the guide oil pipe connecting the liquid - pumping pump and the fuel stove is over - pressured. The fuel is pumped into the temporary storage container and enters the limiting cylinder through the liquid - permeating holes. As the liquid level rises, it drives the floating ball to rise and touches the trigger switch to act, closing the liquid - pumping pump. The excessive fuel can flow back to the oil storage container through the overflow hole, effectively protecting the trigger switch. The fuel is used from the liquid - discharge port, and the liquid level in the temporary storage container drops, driving the floating ball to descend, the trigger switch disconnects, and the liquid - pumping pump restarts to supply oil. By forming flow regulation in the transfer mechanism, the size of the oil supply can be realized, without the need to equip different liquid - pumping pumps according to the required size, thus improving the applicability of the fuel stove and reducing the complexity of selection at the client - end and manufacturing at the production - end.

[0019] 3) The utility model inserts the clamping block into the corresponding slot hole, and uses the fixing part to detachably fix and install the limiting cylinder on the temporary storage container, which is convenient for the disassembly and cleaning of the limiting cylinder and the floating ball, thus improving the practical effect.

[0030] The utility model connects the user-end fuel stove and the oil supply-end liquid extraction pump 2 to form a transfer end and is used for fuel flow regulation. By equipping the liquid extraction pump 2 with a larger firepower specification than the required one and through the intervention of the transfer mechanism of the utility model, the oil supply flow rate can be directly adjusted at the transfer end without adjusting the power of the liquid extraction pump 2, so as to improve the adaptability of the fuel stove 12, effectively avoid the leakage point problem caused by overpressure when the user end is in a state of reducing the firepower or temporarily shutting down, further ensure the safety of use, and improve the practical effect.

[0031] The transfer mechanism also includes a trigger mechanism for triggering the trigger switch 6, and the trigger mechanism includes a float 7 that rises and falls with the liquid level and a limit cylinder 8 mounted on the outside of the float 7.

By forming a flow regulation in the transfer mechanism, the size of the oil supply can be realized, and different liquid pumping pumps 2 do not need to be equipped according to the required size, thereby improving the applicability of the fuel stove 12 and reducing the cumbersome selection of the client and the manufacturing of the production end.
