Description

Technical Field

[0001] This utility model relates to the field of oil drum technology, specifically to a press-type oil drum. Background Technology

[0002] Oil drums, or containers for holding oil, are generally cylindrical in shape made of sheet metal or plastic, with an oil inlet at the top, which is normally sealed with an oil cap. Due to their large size and small inlet, oil extraction is inconvenient. Currently, to facilitate oil extraction, a pumping device is typically purchased. To use it, the cap is first opened, the suction tube of the pumping device is inserted into the oil drum to extract oil, and after extraction, the tube is removed from the drum, and the cap is replaced. This method is not only time-consuming and laborious, requiring the pumping device to be retrieved, the cap opened, oil extracted, the cap replaced, and the pumping device returned to its original position each time, but also results in oil spillage when the suction tube is removed from the drum, causing environmental pollution, difficulty in cleaning, and waste of oil.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] Example 1, in conjunction with Appendix Figure 1-3 A press-dispensing oil drum, comprising an oil drum 1;

[0018] The upper end of the oil drum 1 is provided with an oil outlet pipe 101, which is connected to the inside of the oil drum 1. The oil outlet pipe 101 is connected to a push-type pump head 2, and the liquid inlet end of the push-type pump head 2 is connected to a suction pipe 3. The suction pipe 3 is located inside the oil drum 1, and the lower end of the suction pipe 3 is located at or near the bottom of the oil drum 1.

[0019] In this specific embodiment, the press-type pump head 2 is a very common liquid dispensing device, widely used in products such as hand sanitizer, shampoo, shower gel, lotion, cosmetics, and even some cleaning agents. Its core working principle is to control the flow of liquid using pressure difference and a one-way valve. When using this product, oil is drawn from the oil container 1 by pressing the press-type pump head 2, thus dispensing oil.

[0020] In this specific embodiment, the press-type pump head 2 includes a press head 201, a liquid outlet valve 202, a piston cylinder 203, a piston 204, a spring 205, a liquid inlet valve 206, an end cap 207, and a pressure cap 208.

[0021] The pressing head 201 is equipped with a nozzle 209 and an oil passage 210 communicating with the nozzle 209. An outlet valve 202 is connected to the lower end of the pressing head 201 and communicates with the oil passage 210. The piston 204 is sealed to the piston cylinder 203 and can slide relative to it. The upper end of the piston 204 extends from the piston cylinder 203 and is connected to the outlet valve 202. The piston 204 is equipped with an oil passage 211 communicating with the outlet valve 202. The end cap 207 is connected to the piston cylinder 203. 03. The piston 204 is sealed and fixed, and the upper part of the piston 204 is sealed and fixed to the end cover 207 and can slide relative to each other. The inlet valve 206 is located at the lower end of the piston cylinder 203. The upper end of the suction tube 3 is connected to the inlet end of the inlet valve 206. The spring 205 is located inside the piston cylinder 203 and is located between the piston 204 and the inlet valve 206. The pressure cap 208 is fixed to the outside of the piston cylinder 203. The piston cylinder 203 is inserted into the oil outlet pipe 101. The lower side of the pressure cap 208 is in contact with the upper end of the oil outlet pipe 101.

[0022] The outlet valve 202 is a ball-type check valve, and the inlet valve 206 is a ball-type check valve.

[0023] The functions of each part of the structure in this utility model are as follows:

[0024] Press head 201: The part where the user applies pressure.

[0025] Piston cylinder 203: It has a cylindrical cavity inside, which is used to create a pressure difference and can temporarily store oil. Inside it is a piston 204 that can move up and down.

[0026] Piston 204: Usually equipped with a sealing ring, it moves up and down within the cavity of piston cylinder 203. Moving downwards compresses the cavity volume, while moving upwards increases the cavity volume.

[0027] Spring 205: Located inside the cavity, when pressed and released, spring 205 provides a restoring force to push piston 204 back to its original position.

[0028] Straw 3: Its lower end extends to the bottom of the inner side of the oil drum 1 and is inserted into the oil to transfer the oil.

[0029] Inlet valve 206: As a one-way valve, it only allows oil to flow into the cavity from the suction pipe 3, preventing oil from flowing back into the oil tank 1.

[0030] Discharge valve 202: As a one-way valve, it only allows oil to flow from the cavity to the nozzle 209, preventing air or oil from flowing back into the cavity.

[0031] Nozzle 209: The place where the oil is finally sprayed out.

[0032] Workflow, taking a single press cycle as an example:

[0033] Pressing and discharging oil: The user presses down on the press head 201, compressing the spring 205. The press head 201 pushes the piston 204 downward, compressing the space inside the cavity. The pressure inside the cavity rises sharply, the inlet valve 206 closes, preventing the oil from being forced back into the oil tank 1, and the outlet valve 202 opens. The pressurized oil inside the cavity reaches the nozzle 209 through the second oil channel 211, the open outlet valve 202, and the first oil channel 210. The oil is squeezed out from the nozzle 209.

[0034] Release phase, oil intake: When the user releases the press head 201, the spring 205 rebounds, pushing the piston 204 upward, increasing the volume of the cavity and generating negative pressure inside the cavity. At this time, the outlet valve 202 closes, preventing air from being drawn into the cavity from the nozzle 209, and the inlet valve 206 opens, allowing oil to be drawn into the cavity from the oil tank 1, filling the space created by the piston 204 rising.

[0035] Reset: When the piston 204 rises to the highest point or the user completely releases his hand, the inlet valve 206 closes under the action of gravity or its own structure, sealing the sucked oil in the cavity, and the pressing head 201 returns to the initial position, preparing for the next pressing to pump oil.
