Description

Technical Field

[0001] This utility model belongs to the technical field of water purification equipment, and in particular relates to a water purification device. Background Technology

[0002] In wilderness environments such as field surveys and explorations, obtaining clean water is a critical survival issue. Currently, purifying water from natural bodies of water using water purification equipment is an important way to solve the problem of water use in the wild. However, existing outdoor water purification equipment is relatively complex in structure and requires electricity as a power source, making its use very inconvenient. Therefore, it is necessary to design a simple outdoor water purification device that can operate without electricity. Summary of the Invention

[0003] This invention provides a water purification device to solve the problems mentioned in the background art.

[0004] The technical problem solved by this utility model is achieved by the following technical solution: This utility model provides a water purification device, including a shell, a booster pump and at least four filter elements. The shell has an inlet pipe and an outlet pipe extending outwards, and also includes a water tank. The booster pump, each filter element and the water tank are connected in series through pipelines and installed inside the shell.

[0005] The filter elements are referred to as primary filter element, secondary filter element, tertiary filter element, etc., according to the water inlet sequence. The water inlet pipe is connected to the water inlet end of the primary filter element, and the water outlet pipe is connected to the water tank.

[0006] The booster pump is connected in series between the primary filter element and the secondary filter element;

[0007] The booster pump is a gear pump;

[0008] The booster pump has a detachable rocker arm assembly connected to its drive shaft for driving the booster pump.

[0009] A one-way valve is connected to the pipeline between the booster pump and the secondary filter element.

[0010] As a further technical solution, a pressure gauge is installed on the outside of the housing, and the pressure gauge is connected to the water tank through a pipeline. At the same time, a water outlet valve is installed on the water outlet pipe.

[0011] As a further technical solution, the drive shaft of the booster pump is completely located inside the housing. The rocker arm assembly includes a handle, a rocker arm, a rotating shaft, and a magnetic fixing plate. One end of the rocker arm is hinged to the handle, and the other end of the rocker arm is fixedly connected to one end of the rotating shaft, making the rocker arm perpendicular to the rotating shaft. The other end of the rotating shaft is inserted into a socket on the drive shaft of the booster pump. The magnetic fixing plate is fitted onto the rotating shaft. The housing has a stop that matches the magnetic fixing plate. The magnetic fixing plate is inserted into the stop and magnetically attracted to the housing. An annular boss is machined on the rotating shaft, and the annular boss is sandwiched between the magnetic fixing plate and the housing, thereby mounting the rotating shaft onto the housing.

[0012] As a further technical solution, an internal hexagonal hole is machined on the end face of the shaft that is connected to the rocker arm.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model adopts a hand-cranked design, which can be operated manually without power. Therefore, this utility model is more convenient to use and more practical.

[0015] 2. This utility model has excellent rainproof performance due to the absence of an internal circuit structure, and therefore requires less waterproof performance from the device itself. Furthermore, by eliminating the circuit and sealing structures, this utility model has a simpler structure and higher operational reliability.

[0016] 3. In the field environment, there are many impurities in the water, which can cause great damage to the booster pump. In order to avoid damage to the booster pump, the booster pump is connected in series between the primary filter element and the secondary filter element in this utility model. Before the water enters the booster pump, the primary filter element filters out the large particulate impurities in the water, which can eliminate the adverse effects of impurities in the water on the booster pump.

[0017] 4. This utility model is equipped with a detachable rocker arm assembly. After the rocker arm assembly is disassembled, it is convenient for the transportation and storage of this utility model. In addition, after the rocker arm assembly is removed, a common cordless electric drill can be used as a power source to drive the drive shaft of the booster pump to rotate, thereby realizing the electric drive of this utility model and improving the convenience of use.

[0018] 4. This utility model has a water outlet valve on the water outlet pipe. The water outlet valve allows the water tank to maintain a certain pressure. When the water outlet valve is opened, the pressure in the water tank forces the water to flow out, thus realizing that water can be taken out at any time.

[0019] 5. The pressure gauge is used to display the pressure in the water tank. When using it, the operator can operate according to the pressure gauge reading. Once the pressure gauge reaches the predetermined reading, the operation can be stopped. When the pressure gauge drops below the predetermined reading, the booster pump will be driven again.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figure 1 As shown, this embodiment includes a housing 1, a booster pump 2, and at least four filter elements. The housing 1 has an inlet pipe 5 and an outlet pipe 8 extending outwards. The above is a common structure in the prior art, and will not be described again.

[0025] The present invention is characterized in that it also includes a water tank 9, a booster pump 2, and each filter element and the water tank 9 are connected in series through pipelines and installed in the housing 1; the filter elements are respectively called primary filter element 3, secondary filter element 4, tertiary filter element, etc. according to the water inlet sequence, the water inlet pipe 5 is connected to the water inlet end of the primary filter element 3, and the water outlet pipe 8 is connected to the water tank 9.

[0026] The booster pump 2 is connected in series between the primary filter element 3 and the secondary filter element 4. In the field environment, there are many impurities in the water, which can cause significant damage to the booster pump. To avoid damage to the booster pump 2, this invention connects the booster pump 2 in series between the primary filter element 3 and the secondary filter element 4. Before the water enters the booster pump 2, it passes through the primary filter element 3 to filter out large particles of impurities in the water, thus eliminating the adverse effects of impurities on the booster pump 2.

[0027] The booster pump 2 is a gear pump;

[0028] The booster pump 2 has a detachable rocker arm assembly connected to its drive shaft 17 for driving its operation. This invention features a hand-cranked design, allowing operation by hand even without power, making it more convenient and practical.

[0029] A one-way valve 10 is connected to the pipeline between the booster pump 2 and the secondary filter element 4.

[0030] A pressure gauge 6 is installed on the outside of the housing 1. The pressure gauge 6 is connected to the water tank 9 via a pipe. A water outlet valve 7 is installed on the water outlet pipe 8. This invention uses a water outlet valve 7 on the water outlet pipe 8 to maintain a certain pressure inside the water tank 9. When the water outlet valve 7 is opened, the pressure inside the water tank 9 forces water to flow out, thus providing water on demand. Additionally, the pressure gauge 6 displays the pressure inside the water tank 9. During use, the operator can operate according to the indication of the pressure gauge 6. Operation can be stopped once the pressure gauge 6 reaches a predetermined reading. When the pressure gauge 6 drops below the predetermined reading, the booster pump 2 is activated again.

[0031] like Figure 1 As shown, the drive shaft 17 of the booster pump 2 is completely located inside the housing 1. The rocker arm assembly includes a handle 11, a rocker arm 12, a rotating shaft 15, and a magnetic fixing plate 13. One end of the rocker arm 12 is hinged to the handle 11, and the other end of the rocker arm 12 is fixedly connected to one end of the rotating shaft 15, making the rocker arm 12 perpendicular to the rotating shaft 15. The other end of the rotating shaft 15 is inserted into a hole on the drive shaft 17 of the booster pump 2. The magnetic fixing plate 13 is fitted onto the rotating shaft 15. The housing 1 is provided with a stop that matches the magnetic fixing plate 13. The magnetic fixing plate 13 is inserted into the stop and magnetically attracted to the housing 1. The rotating shaft 15 is machined with an annular boss 16, which is sandwiched between the magnetic fixing plate 13 and the housing 1, thereby mounting the rotating shaft 15 onto the housing 1. This utility model features a detachable rocker arm assembly, which facilitates the transportation and storage of the utility model after disassembly. Furthermore, after the rocker arm assembly is removed, a common cordless electric drill can be used as a power source to drive the drive shaft 17 of the booster pump 2 to rotate, thereby realizing the electric drive of this utility model and improving the ease of use.

[0032] The end face of the rotating shaft 15 connected to the rocker arm 12 is machined with an internal hexagonal hole 14. The operator can also drive the booster pump 2 by using a hand drill to engage with the internal hexagonal hole 14 without disassembling the rocker arm assembly.
