Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1-3 As shown, this utility model embodiment provides a dual-purpose water purifier for home and outdoor use, including a shell 1, an inlet 101 and an outlet 102 disposed inside the shell, and a filter element 3 disposed inside the shell; the outlet is connected to the upper end of the filter element, that is, the upper end of the filter element is located outside the shell 1 and the connection between the two is sealed; a check valve 2 fixedly connected to the shell is provided at the inlet 101; when used at home or in the wild, external water enters the shell 1 through the check valve. Here, the inlet and the check valve are integrated. At home, tap water enters through the check valve 2. When in the wild, when water is taken from a stream, the water also enters the water purifier through this point; the external water mainly refers to tap water and outdoor water, such as stream water.

[0019] like Figure 4-8As shown, specifically in this embodiment, the check valve 2 includes a main body 201, a front cover 202 located at the outer end of the main body and outside the outer casing 1, a rear cover 203 located at the inner end of the main body and inside the outer casing, and a sealing plate 204 located inside the main body and movably connected to the rear cover; the sealing plate is used to close or open the water passage inside the check valve. The main body 201, the front cover 202, and the outer casing 1 are fixedly connected by ultrasonic welding.

[0020] Here, the main body 201, the front cover 202, and the rear cover 203 are all cylindrical; the axial water inlet holes 2a inside the three are interconnected to form the water passage of the check valve; the sealing plate 204 is disc-shaped, and its diameter is larger than the diameter of the axial water inlet hole 2a inside the main body; the sealing plate can move inside the main body 201 along the main body axis; the sealing plate in this embodiment is made of flexible material, that is, the sealing plate is deformable; the sealing plate 204 here is made of rubber material.

[0021] like Figure 1-2 and Figure 9 As shown, the bottom of the outer casing 1 is also provided with a bottom cover 6, and the two are welded together by ultrasonic welding.

[0022] like Figure 2 , Figure 5 As shown, the outer wall of the main body 201 is provided with a radial protruding ring 201a integrally formed therewith; the radial protruding ring is located inside the outer shell 1 and abuts against the inner wall of the outer shell; the front end of the main body 201 passes through the water inlet 101 and is located outside the outer shell and is fixedly connected to the front cover 202.

[0023] To install the sealing plate 204, a connecting shaft 7 is provided on the inner wall of the rear cover 203. One end of the connecting shaft is fixedly connected to the shaft and parallel to the axial direction of the rear cover. The other end of the connecting shaft is located inside the main body 201 and passes vertically through the sealing plate 204, connecting to it. That is, the sealing plate 204 can move on the connecting shaft 7. Correspondingly, the sealing plate is elliptical in shape and has a through hole at the top, through which the connecting shaft 7 moves. A blind hole 201b is provided inside the main body 201, parallel to the axial water inlet hole 2a inside the main body 201. The other end of the connecting shaft is inserted into the blind hole 201b, which limits the position of the sealing plate 204.

[0024] The main body 201 of the check valve 2 is provided with a positioning plane A that matches the outer shell 1. After the main body 201 of the check valve passes through the inlet 101 inside the outer shell 1, the positioning plane is fixedly connected to the outer shell 1 to prevent the main body 201 from moving and to ensure that the movable sealing plate 204 always moves along the axial direction of the main body 201.

[0025] Specifically, such as Figure 2-3As shown, the water inlet 101 is located inside the lower end of one side panel of the outer casing 1; the water outlet is located inside the upper cover 1a of the outer casing 1.

[0026] like Figure 2 , Figure 10 As shown, in order to collect water in the field and pressurize the collected water into the filter element 3 for filtration, a piston assembly 4 is also included. This assembly includes a piston cylinder 401, a piston rod 402 inserted into it at its lower end, a piston 403 located at the inner end of the piston rod, and a sealing ring 404 fitted onto the piston. The upper end of the piston cylinder 401 passes through the upper cover 1a of the outer shell and is located outside the outer shell. Here, the piston cylinder 401 is integrally formed with the outer shell 1. like Figure 2 As shown, specifically, the upper end of the piston rod 402 is located outside the piston cylinder 401, and a handle 5 perpendicular to it is provided at the upper end of the piston rod. The handle 5 is fixedly connected to the upper end of the piston rod 402 by ultrasonic welding.

[0027] The piston cylinder 401 is arranged vertically along the outer shell 1, and its lower end is provided with an opening communicating with the interior of the outer shell; the piston cylinder is located above the check valve 2.

[0028] The sealing ring 404 has a V-shaped cross-section, and its outer wall is in contact with the inner wall of the piston cylinder 401.

[0029] like Figure 12 As shown, using the above structure, in field use, the hose 8 connects the water distributor 9 and the water purifier. The water distributor 9 is placed in the stream 10. When the handle 5 is lifted to pump water, the piston rod 402 and piston 403 move upwards, preventing the sealing plate 204 from sealing the axial water inlet hole 2a inside the main body 201, allowing raw water to smoothly enter the outer shell cavity. When the handle 5 is pressed down, the sealing plate 204 is pressed against the outside of the axial water inlet hole 2a inside the main body 201, blocking the cavity and preventing raw water from flowing out. It is forced to flow through the micropores of the filter element to produce purified water, thus achieving filtration.

[0030] like Figure 2 , Figure 3 , Figure 12 As shown, the water outlet is connected to the upper end of the filter element, that is, the upper end of the filter element is located outside the outer shell 1 and the connection between the two is sealed; the main body 201, the front cover 202 and the outer shell 1 are fixedly connected by ultrasonic welding; the sealing ring 404 is sleeved on the piston, the cross-section of the sealing ring 404 is V-shaped, and its outer wall is in contact with the inner wall of the piston cylinder 401; the bottom of the outer shell 1 is also provided with a bottom cover 6 and the two are ultrasonically welded; it is shown that the outer shell 1 is a whole, and all its openings and connections with other parts are connected by ultrasonic welding or sealing, thereby forming a closed space inside the outer shell.

[0031] When the handle 5 is lifted to pump water, piston rod 402 and piston 403 move upwards, as... Figure 2 As shown, this process is equivalent to evacuating the sealed space inside the shell. The pressure inside the sealed space is less than the pressure outside the shell. Under the action of the pressure difference between the inside and outside, because "the sealing plate can move inside the main body 201 and along the main body axis, that is, the sealing plate 204 can move on the connecting shaft 7", the sealing plate moves away from the axial water inlet 2a inside the main body. Therefore, at this time, the sealing plate 204 cannot seal the axial water inlet 2a inside the main body 201. Conversely, when the handle 5 is pressed down, the piston rod 402 and piston 403 move down, compressing the sealed space. Under this pressure, the sealing plate moves towards the axial water inlet 2a inside the main body until the sealing plate 204 is in contact with the vertical surface inside the main body 201 and is pressed against the vertical surface by the pressure (the inner end opening of the axial water inlet 2a inside the main body is set on the vertical surface). Therefore, at this time, the axial water inlet 2a inside the main body is sealed. Figure 4 As shown.

[0032] In summary, such as Figure 12-13 As shown, for home use, the hose 8 connects the three-way ball valve 11 to the water purifier. Opening the three-way ball valve 11 allows tap water to flow into the purifier, where it is filtered and purified by the filter element 3, producing purified water. For outdoor use, the hose 8 connects the water distributor 9 to the purifier. Placing the water distributor 9 in a stream and lifting the handle 5 allows water to be drawn in. Pressing the handle 5 down blocks the axial inlet hole 2a in the check valve 2, forcing the drawn-in water into the filter element 3 for filtration and purification, producing purified water. Compared to existing technologies, this water purifier is suitable for both home and outdoor use, offering wide applicability and ease of use.

[0033] In the above description, it should be noted that the terms "installation", "connection", "connection" and other related terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; "set at" should be understood as "installed at" or "set at", including installation methods such as fixed installation and movable installation.

[0034] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
