Description

Technical Field

[0001] This utility model relates to the field of food processing tools, and in particular to a press-type oil dispenser. Background Technology

[0002] Traditional oil bottles require lifting the heavy bottle and tilting it to pour oil, which is quite cumbersome. However, a press-type oil dispenser can be operated with one hand. During cooking, one hand holds the spatula while the other hand can easily press the dispenser to dispense oil, improving cooking efficiency. When stir-frying, it is necessary to quickly add a little oil to the pan to prevent food from sticking. Using a press-type oil dispenser can quickly accomplish this task.

[0003] A search revealed Chinese patent publication number CN218606295U, which relates to the field of oil dispensers and discloses a press-type oil dispenser for easy manual pressing. The dispenser includes a can body, a fixed tube fixedly connected to the top of the can body, a sealing ring movably connected to the outer wall of the fixed tube, a mounting plate movably connected to the outer wall of the fixed tube, a connecting plate fixedly connected to the inner top wall of the mounting plate, a connecting tube fixedly connected to the bottom of the connecting plate, and a transition tube fixedly connected to one end of the connecting tube. This press-type oil dispenser for easy manual pressing... The oil control can is designed with a tank body, sealing ring, mounting plate, connecting plate, connecting pipe, transition pipe, oil inlet pipe, oil pressure pipe, fixing frame, pressure ball, spring, pressure rod, limit block, and feed port, making it easy to manually press the oil dispenser. This facilitates manual oil dispensing, preventing excessive oil addition and meeting work needs. It also improves the efficiency of the oil control can and brings convenience to people's work. However, in actual use, repeated pressing over a long period of time can leave oil residue at the pump body joints, which can cause contamination over time. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a press-type oil dispenser, which aims to improve the problem that oil will remain in the pump body after repeated pressing in the prior art, and long-term accumulation will cause pollution.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a press-type oil dispenser, comprising a hollow dispenser, a closed cover fixedly connected to the top of the hollow dispenser, a pump body fixedly connected to the bottom of the closed cover, an oil inlet valve fixedly connected to the bottom of the pump body, a top cover rotatably connected to the top of the closed cover, a pressing tube slidably connected inside the top cover, a piston fixedly connected to the bottom of the pressing tube, a pump head rotatably connected to the top of the pressing tube, an oil outlet valve fixedly connected to one side of the pump head, a return pipe connected to the rear side of the closed cover, the other end of the return pipe connected to the bottom of the hollow dispenser, and a fixing mechanism provided on the top of the hollow dispenser.

[0006] Through the above technical solution: the pressing tube, which is rotatably connected to the pump head, moves downwards, and the piston at the bottom of the pressing tube also moves downwards within the pump body. This process reduces the internal space of the pump body and increases the pressure. Due to the one-way nature of the inlet valve, the inlet valve closes at this time to prevent oil from flowing back into the hollow container. Meanwhile, the outlet valve on one side of the pump head opens under pressure, allowing the oil inside the pump body to flow through the outlet valve to the pressing tube and finally out of the pump head, thus realizing the oil pouring operation. When the pump head is released, the pressing tube moves downwards on its own... Under the action of elastic force, the piston rebounds upward, increasing the internal space of the pump body and reducing the pressure. At this time, the oil outlet valve closes to prevent oil backflow, while the oil inlet valve opens. Under the action of pressure difference, the oil in the hollow container enters the pump body through the oil inlet valve, preparing for the next press to pour oil. The return pipe on the back of the sealed cover connects to the bottom of the hollow container. Its function is to allow the oil to flow back to the hollow container in some special cases, such as when there is residual oil in the pump body or related pipelines, so as to avoid oil residue on external parts, which would cause waste or contamination.

[0007] As a further description of the above technical solution:

[0008] The fixing mechanism includes an annular column, the bottom of which is fixedly connected to the top of the hollow kettle. A limiting groove is formed on the outer wall of the annular column, a limiting block is slidably connected to the top of the annular column, a limiter is slidably connected to the front side of the limiting block, and a reserved hole is formed on one side of the top cover.

[0009] The above technical solution involves aligning the pre-drilled hole on one side of the top cover with the limiting block at the top of the annular column, and then placing the top cover downwards onto the annular column. At this time, the limiting block slides on the top of the annular column and moves along the trajectory of the limiting groove, thus ensuring the accuracy and stability of the top cover's position during installation. After the top cover is installed in place, to prevent it from accidentally falling off or shifting, a locking function is achieved by sliding the limiter to the front side of the limiting block. The limiter is slid into a specific position so that it fits tightly with the limiting block, limiting the excessive movement of the limiting block on the annular column, thereby firmly fixing the top cover to the hollow kettle.

[0010] As a further description of the above technical solution:

[0011] The hollow kettle has a handle fixedly connected to its left side, and the right side of the handle has a rounded design.

[0012] The above technical solution involves fixing the handle to the left side of the hollow oil bottle, making it convenient for users to hold the oil bottle. The right side is designed with a smooth edge, so that the user's hand will not be scratched by the sharp edge during the holding process, providing a comfortable holding experience.

[0013] As a further description of the above technical solution:

[0014] Two connecting blocks are fixedly connected to the rear side of the hollow kettle, and buckles are fixedly connected to the rear side of the two connecting blocks. The inside of the two buckles is clamped to the outer wall of the return pipe.

[0015] The above technical solution involves two connecting blocks fixed to the rear side of the hollow kettle, which act as a bridge connecting the buckle and the hollow kettle. The buckle is fixed to the rear side of the connecting blocks and is internally clamped to the outer wall of the return pipe.

[0016] As a further description of the above technical solution:

[0017] A measuring ruler is fixedly connected to the front side of the hollow kettle, and multiple graduations are equidistantly opened on the front side of the measuring ruler.

[0018] The above technical solution involves fixing a measuring ruler to the front of the hollow kettle, with multiple equidistant graduations on the front that allow users to intuitively understand the remaining amount of oil in the kettle.

[0019] As a further description of the above technical solution:

[0020] Each of the four corners of the bottom of the hollow kettle is fixedly connected with a pad, and the bottom of each of the pads is fixedly connected with a rubber pad.

[0021] The above technical solution involves fixing four pads at the four corners of the bottom of the hollow pot to provide stable support for the oil pot. The rubber pads at the bottom of the pads can increase friction and prevent the oil pot from easily sliding on the flat surface.

[0022] As a further description of the above technical solution:

[0023] The top of the annular column is provided with an annular groove, and the bottom of the limiting block is fixedly connected with an arc-shaped block.

[0024] The above technical solution enables the top cover to be installed more accurately on the annular column, enhancing the stability and precision of the connection between the top cover and the hollow kettle.

[0025] As a further description of the above technical solution:

[0026] The rear end of the limiter passes through the limit block and is slidably connected inside the reserved hole, and the size of the limit block matches that of the reserved hole.

[0027] The above technical solution is used to fix the top cover. After the top cover is installed, the position of the limiter can be adjusted to lock the limit block in the reserved hole, thereby ensuring that the top cover is firmly fixed on the hollow kettle.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, pressing the pump head causes the pressing tube and piston, which are rotatably connected to it, to move downward in the pump body. The pump body space decreases and the pressure increases. The oil inlet valve closes and the oil outlet valve opens to realize oil pouring. When the pump head is released, the pressing tube rebounds, the pump body pressure decreases, the oil outlet valve closes, the oil inlet valve opens to allow oil to enter, and the residual oil is returned to the hollow container through the return pipe, avoiding waste and pollution.

[0030] 2. In this utility model, by aligning the pre-drilled hole on one side of the top cover with the top limiting block of the annular column, and then fitting it down onto the annular column, the limiting block slides along the limiting groove, ensuring the accuracy and stability of the top cover installation position. After the top cover is installed, the limiting device is slidably connected to the front side of the limiting block, and the limiting device is slid into a specific position to fit tightly, restricting the movement of the limiting block, so that the top cover is firmly fixed on the hollow kettle.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a press-type oil reservoir, comprising a hollow reservoir 1 for storing oil. A sealing cap 3 is fixedly connected to the top of the reservoir, sealing the top opening of the reservoir 1 and providing a mounting base for other components. A pump body 4 is fixedly connected to the bottom of the sealing cap 3. The pump body 4 is a key component for generating pressure to drive the oil flow. An oil inlet valve 5 is fixedly connected to the bottom of the pump body 4, controlling the oil entry into the pump body 4 and preventing backflow. A top cover 6 is rotatably connected to the top of the sealing cap 3, providing some protection for internal components and facilitating operation. The top cover 6 has an internal sliding mechanism. A pressing tube 7 is connected, which can move up and down under pressure. A piston 8 is fixedly connected to the bottom of the pressing tube 7. The piston 8 can move inside the pump body 4 to change the pressure. A pump head 9 is rotatably connected to the top of the pressing tube 7. The pump head 9 makes it convenient for the user to apply pressure. An oil outlet valve 10 is fixedly connected to one side of the pump head 9. The oil outlet valve 10 controls the flow of oil from the pump body 4 to the outside. A return pipe 11 is connected to the rear side of the sealing cover 3. The return pipe 11 allows the oil to flow back to the bottom of the hollow pot 1. A fixing mechanism 2 is provided on the top of the hollow pot 1. The fixing mechanism 2 is used to achieve a stable connection and convenient operation between the hollow pot 1 and the top cover 6.

[0040] Specifically, pressing the pump head 9 and the pressing tube 7, which is rotatably connected to the pump head 9, will move downwards. The piston 8 at the bottom of the pressing tube 7 will also move downwards within the pump body 4. This process reduces the internal space of the pump body 4 and increases the pressure. Due to the one-way conductivity of the oil inlet valve 5, the oil inlet valve 5 closes at this time to prevent oil from flowing back into the hollow container 1. Meanwhile, the oil outlet valve 10 on one side of the pump head 9 opens under pressure, allowing the oil inside the pump body 4 to flow through the oil outlet valve 10 to the pressing tube 7, and finally out of the pump head 9, thus completing the oil pouring operation. When the pump head 9 is released, the pressing tube 7... Under the action of elastic force, the piston 8 rebounds upward, and the internal space of the pump body 4 increases, the pressure decreases, and the oil outlet valve 10 closes to prevent oil backflow, while the oil inlet valve 5 opens. Under the action of pressure difference, the oil in the hollow bottle 1 enters the pump body 4 through the oil inlet valve 5, preparing for the next press to pour oil. The return pipe 11 on the back side of the sealing cover 3 is connected to the bottom of the hollow bottle 1. Its function is to allow the oil to flow back to the hollow bottle 1 in some special cases, such as when there is residual oil in the pump body 4 or related pipes, so as to avoid oil residue on external parts causing waste or pollution.

[0041] Reference Figure 1 and Figure 4 The fixing mechanism 2 includes an annular column 201, the bottom of which is fixedly connected to the top of the hollow pot 1 to form an overall support frame. A limiting groove 202 is formed on its outer wall, providing a guide path for the sliding of related components. A limiting block 203 is slidably connected to the top of the annular column 201, and the limiting block 203 can move on the top of the annular column 201 and is constrained by the limiting groove 202. A limiter 204 is slidably connected to the front side of the limiting block 203, controlling the locking and unlocking states of the limiting block 203. A reserved space is provided on one side of the top cover 6. Hole 205 provides space for the fit between the limiting block 203 and the limiter 204. The top of the annular column 201 has an annular groove 19, which fits with the arc block 20 fixedly connected to the bottom of the limiting block 203. The arc block 20 can slide in the annular groove 19 for further precise positioning. The rear end of the limiter 204 passes through the limiting block 203 and slides inside the reserved hole 205, thereby adjusting the fixed position of the top cover 6. The size of the limiting block 203 and the reserved hole 205 are matched to ensure that the connection of each component is tight and stable.

[0042] Specifically, when installing the top cover 6, align the pre-drilled hole 205 on one side of the top cover 6 with the limiting block 203 on the top of the annular post 201, and then slide the top cover 6 downwards onto the annular post 201. At this time, the limiting block 203 slides on the top of the annular post 201 and moves along the trajectory of the limiting groove 202, thereby ensuring the accuracy and stability of the top cover 6 during installation. After the top cover 6 is installed in place, to prevent it from accidentally falling off or shifting, a locking function is achieved by sliding the limiter 204 with the front side of the limiting block 203. The limiter 204 is slid into... The top cover 6 is positioned to fit tightly with the limiting block 203, limiting the excessive movement of the limiting block 203 on the annular post 201, thereby firmly fixing the top cover 6 to the hollow pot 1. This guides and restricts the installation position of the top cover 6, allowing it to be installed more accurately on the annular post 201, enhancing the stability and precision of the connection between the top cover 6 and the hollow pot 1. After the top cover 6 is installed, the position of the limiting device 204 can be adjusted to lock the limiting block 203 within the reserved hole 205, thus ensuring that the top cover 6 is firmly fixed to the hollow pot 1.

[0043] Reference Figure 1 , Figure 2 and Figure 5A handle 12 is fixedly connected to the left side of the hollow kettle 1, making it convenient for users to hold and operate the kettle. The right side features a smooth design to prevent hand injuries and provide a more comfortable grip. Two connecting blocks 13 are fixedly connected to the rear side of the hollow kettle 1. These connecting blocks 13 serve to connect and secure subsequent components. Buckles 14 are fixedly connected to the rear of the two connecting blocks 13, used to secure specific components and prevent them from shaking. The interior of the two buckles 14 is clamped to the outer wall of the return pipe 11, thereby ensuring... The return pipe 11 is in a stable position. A measuring scale 15 is fixedly connected to the front of the hollow container 1. The measuring scale 15 can intuitively display the oil level information. Multiple scales 16 are equidistantly opened on the front of the measuring scale 15. The scales 16 can accurately measure the remaining amount of oil in the hollow container 1. A pad 17 is fixedly connected to the four corners of the bottom of the hollow container 1. The pad 17 provides a stable support base for the hollow container 1. A rubber pad 18 is fixedly connected to the bottom of the multiple pads 17. The rubber pad 18 can increase friction to prevent the oil container from sliding and can cushion and protect the container body.

[0044] Specifically, the handle 12 is fixed to the left side of the hollow bottle 1 for easy gripping. Its right side features a rounded design, preventing the user's hand from being scratched by sharp edges and providing a comfortable grip. To secure the return pipe 11 and prevent it from shaking or shifting, a measuring ruler 15 is fixed to the front of the hollow bottle 1. Multiple equidistant graduations 16 on the front allow the user to visually understand the remaining amount of oil in the hollow bottle 1. Four pads 17 are fixed to the four corners of the bottom of the hollow bottle 1, providing stable support. The rubber pads 18 at the bottom of the pads 17 increase friction, preventing the bottle from easily sliding on the surface.

[0045] Working principle: When using the press-type oil can, the press pump head 9 and the press tube 7, which is rotatably connected to the pump head 9, move downwards. The piston 8 at the bottom of the press tube 7 also moves downwards within the pump body 4. This process reduces the internal space of the pump body 4 and increases the pressure. Due to the one-way conduction of the oil inlet valve 5, the oil inlet valve 5 closes at this time to prevent oil from flowing back into the hollow can 1. Meanwhile, the oil outlet valve 10 on one side of the pump head 9 opens under pressure, allowing the oil in the pump body 4 to flow through the oil outlet valve 10. The oil flows to the pressing tube 7 and finally out of the pump head 9, realizing the oil pouring operation. When the pump head 9 is released, the pressing tube 7 rebounds upward under its own elastic force, and the piston 8 rises accordingly. The internal space of the pump body 4 increases and the pressure decreases. At this time, the oil outlet valve 10 closes to prevent oil backflow, while the oil inlet valve 5 opens. The oil in the hollow canister 1 enters the pump body 4 through the oil inlet valve 5 under the action of pressure difference, preparing for the next pressing to pour oil. The return pipe 11 on the back side of the sealing cap 3 connects to the hollow canister. The bottom section serves to allow oil to flow back to the hollow container 1 in special circumstances, such as when there is residual oil in the pump body 4 or related pipelines. This prevents oil from being wasted or contaminated by residue on external parts. When installing the top cover 6, the pre-drilled hole 205 on one side of the top cover 6 is aligned with the limiting block 203 on the top of the annular column 201. Then, the top cover 6 is placed downwards onto the annular column 201. At this time, the limiting block 203 slides on the top of the annular column 201 and moves along the trajectory of the limiting groove 202, thereby ensuring the accuracy and stability of the top cover 6 during installation. After the top cover 6 is installed in place, to prevent it from accidentally falling off or shifting, a locking function is achieved by sliding the limiter 204 to the front side of the limiting block 203. The limiter 204 is slid into a specific position so that it fits tightly with the limiting block 203, limiting the excessive movement of the limiting block 203 on the annular column 201, thereby firmly fixing the top cover 6 to the hollow container 1.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
