Description

Technical Field

[0001] This utility model relates to the field of manual water pump technology, specifically a novel manual water pump. Background Technology

[0002] Bottled purified water is safe and requires no installation, making it suitable for use in homes, offices, and other settings. However, bottled purified water typically requires a water pump, which is often too large to fold, store, or carry easily.

[0003] Manual water pumps require pressing to dispense water, making it difficult to precisely control the water flow. They also have a slow rebound when pressed, resulting in low efficiency. Furthermore, they typically have a complex internal structure and use screws inside, making them prone to aging and rusting over time. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing manual water pumps are large in size, inconvenient to carry, and have a complex structure.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model proposes a novel manual water pump, comprising a pump body and a pump cover connected to the top via a snap-fit ​​mechanism. A U-shaped groove is provided on one side of the pump body, and a water outlet connector is slidably disposed within the U-shaped groove. The water outlet connector is pressed and fixed by the pump cover. One end of the water outlet connector is connected to a water outlet nozzle. It employs a mechanical drive, utilizing the lever principle to convert the applied operating force into a mechanical action of opening / closing the valve. No power supply is required. It features high reliability, simple structure, low maintenance cost, and precise water flow control. The other end of the water outlet connector penetrates the main body of the pump and extends downwards. A water inlet pipe is connected to the lower end of the water outlet connector. The main body of the pump also contains a pressure-pressurizing body. The bottom of the pressure-pressurizing body is open and equipped with a first one-way valve. An air-pressurizing connecting rod is slidably mounted through the top cover of the pump. A sealing piston is slidably mounted inside the pressure-pressurizing body at the bottom of the air-pressurizing connecting rod. A second one-way valve is mounted on the sealing piston. A lifting handle is mounted at the top of the air-pressurizing connecting rod.

[0006] Preferred technical solution 1: It also includes a barrel opening fixing ring, the inner ring of which is provided with an internal thread and is threadedly connected to the bottom of the water pump body. The barrel opening fixing ring is also provided with a pressing component, and multiple sets of the pressing component are evenly distributed around the central axis of the barrel opening fixing ring and are inclined.

[0007] Preferred technical solution 2: Multiple sets of protrusions are evenly distributed on the outer side of the barrel mouth fixing ring.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0020] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A novel manual water pump includes a pump body 1 and a pump cover 2 connected to the top by a snap-fit. A U-shaped groove 3 is provided on one side of the pump body 1, and a water outlet connector 4 is slidably arranged in the U-shaped groove 3. The water outlet connector 4 is pressed and fixed by the pump cover 2. One end of the water outlet connector 4 is connected to a water outlet nozzle 5. It adopts mechanical drive and utilizes the lever principle to convert the applied operating force into the mechanical action of opening / closing the valve. It does not require a power supply, has high reliability, simple structure, low maintenance cost, and achieves precise control of water flow. The other end of the water outlet connector 4 passes through the pump body 1 and extends to the bottom. A water inlet pipe 6 is connected to the bottom end of the water outlet connector 4. In order to pressurize the water inside the tank, a pump is also provided inside the pump body 1. The main body 7 is a pressure unit. The bottom of the pressure unit 7 is open and equipped with a first one-way valve. An air-pressurizing connecting rod 8 is slidably mounted through the top cover 2 of the water pump. The bottom of the air-pressurizing connecting rod 8 is equipped with a sealing piston 9 that is slidably mounted inside the pressure unit 7. The sealing piston 9 is equipped with a second one-way valve. The top of the air-pressurizing connecting rod 8 is equipped with a lifting handle 10. In actual use, by lifting the handle 10, the air-pressurizing connecting rod 8 is pushed down inside the pressure unit 7 to close the second one-way valve and open the first one-way valve to allow air to enter the water tank. When the lifting handle 10 is pulled out, the first one-way valve closes to maintain the pressure inside the water tank. At the same time, the second one-way valve opens the air intake. When water is needed, the water outlet faucet 5 is opened. The water is discharged from the water outlet faucet 5 through the water inlet pipe 6 and the water outlet connector 4 by utilizing the principle that the pressure inside the water tank is greater than the external pressure.

[0021] like Figure 3As shown, to facilitate connection with the water bucket, a bucket opening fixing ring 11 is also included. The inner ring of the bucket opening fixing ring 11 has an internal thread 12 and is threadedly connected to the bottom of the water pump body 1. The bucket opening fixing ring 11 also has a pressing member 13. Multiple sets of pressing members 13 are evenly distributed around the central axis of the bucket opening fixing ring 11 and are inclined. The bucket opening is connected and fixed by pressing the multiple sets of pressing members 13. In order to facilitate rotation and fixation, multiple sets of protrusions 14 are evenly distributed on the outer side of the bucket opening fixing ring 11.

[0022] Among them, the water inlet pipe 6 is a food-grade silicone hose, which can reach the water at the bottom of the bucket during use, and will not cause the bottom water to be unable to be pumped up.

[0023] In practical use, align the bucket opening fixing ring 11 at the bottom of the water pump body 1 with the water bucket opening, and rotate the bucket opening fixing ring 11 clockwise. The evenly distributed inclined extrusion parts 13 on the inner ring of the bucket opening fixing ring 11 will be screwed in with the thread, generating radial clamping force to stably connect the water bucket. The food-grade silicone hose is fully inserted into the bottom of the water bucket, with the hose naturally bent to fit against the bucket wall, and the end ≤5mm from the bottom of the bucket to avoid residual water that cannot be pumped out. Hold the lifting handle 10 and press down to drive the air pump connecting rod 8 to push the sealing piston 9 down. When the second one-way valve is closed under pressure, it isolates external air. The first one-way valve opens, and compressed air is injected into the water bucket through the bottom opening. Pull the handle 10 upward to move the sealing piston 9 upward. The first one-way valve closes, and the air pressure in the water bucket is maintained to prevent backflow of gas. The second one-way valve opens, and external air enters the pressurizing body 7 through the air pumping connecting rod 8 to replenish the negative pressure in the cavity. Press repeatedly 3-5 times to stabilize the air pressure in the water bucket to 0.08-0.1MPa. Open the handle of the water outlet 5 to precisely control the water output.
