[0002] Negative pressure water supply equipment is usually used to provide negative pressure in the water supply system to transport water from a lower place to a higher place. This equipment usually includes components such as a negative pressure pump or a vacuum pump, which sucks water from a low-pressure area by means of negative pressure, and then pumps the water into a high-pressure area. Negative pressure water supply equipment can be used in buildings, industrial production, agricultural irrigation and other fields, providing an effective solution for water transportation.

[0003] The Chinese patent "leakage-proof non-negative pressure water supply equipment" authorization announcement number "CN219887034U" uses a filter element, sleeve and fixed base to filter the water inside the connecting pipe and replace the filter element, thereby avoiding the formation of scale in the connecting pipe.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] It should be noted that the flow stabilizing tank 1, connecting pipe 2, water pump unit 3, water outlet pipe 4 and filter element 53 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the flow stabilizing tank 1 and the water pump unit 3 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0026] When water supply is required, the water pump unit 3 is manually turned on, and the water in the swirl tank 1 flows into the corresponding filter element 53 through the connecting pipe 2 for filtration, and then is transported to the water outlet pipe 4 through the water pump unit 3. The water in the water outlet pipe 4 is transported to the corresponding position for water supply. When water supply is not required, the water pump unit 3 is manually turned off.

[0027] When it is necessary to replace the filter element 53 that has been used for a period of time, one of the water-blocking rods 54 is driven downward to close one of the control cylinders 51, and the other water-blocking rod 54 is driven upward to unblock the other control cylinder 51. The water in the connecting pipe 2 flows into the other filter element 53 through the other control cylinder 51 for filtration, and one of the cover plates 514 is pulled to open one of the filter cylinders 52. At this time, the filter element 53 that has been used for a period of time can be replaced without shutting down the negative pressure water supply equipment.

[0028] like Figure 4 As shown, a mounting bracket 55 is fixedly connected to the surface of the control cylinder 51, a threaded rod 56 is threadedly connected to the inner wall of the mounting bracket 55, the bottom end of the threaded rod 56 is rotatably connected to the top end of the water blocking rod 54, a connecting bracket 57 is fixedly connected to the surface of the water blocking rod 54, a mounting rod 58 is fixedly connected to the bottom of the connecting bracket 57, the surfaces of the mounting rod 58 are respectively clamped to the cover plate 514 and the inner wall of the filter cylinder 52, the mounting rod 58 is shaped like a truncated cone, a fixing rod 511 is slidably connected to the inner wall of the threaded rod 56, the surface of the fixing rod 511 is clamped to the inner wall of the mounting bracket 55, a driven rod 512 is fixedly connected to the top end of the water blocking rod 54, the surface of the driven rod 512 is slidably connected to the inner wall of the mounting bracket 55, and a lifting block 513 is fixedly connected to the inner side of the filter element 53.

[0029] One of the threaded rods 56 is rotated, and one of the threaded rods 56 rotates and moves downward in the mounting frame 55, driving one of the water-blocking rods 54 to move downward and contact the inner bottom wall of one of the control cylinders 51. The downward movement of one of the water-blocking rods 54 drives one of the connecting frames 57 and the mounting rod 58 to move downward, so that one of the mounting rods 58 is clamped into one of the cover plates 514 and the filter cylinder 52, so that one of the control cylinders 51 is in a blocked state. The other threaded rod 56 is rotated, and the other threaded rod 56 rotates and moves upward in the mounting frame 55, driving the other water-blocking rod 54 to move upward. The upward movement of the other water-blocking rod 54 drives one of the connecting frames 57 and the mounting rod 58 to move upward, so that the other mounting rod 58 is away from the other cover plate 514 and the filter cylinder 52, so that the other control cylinder 51 is in a unblocked state. At this time, the other cover plate 514 is pulled to make the other filter cylinder 52 unblocked, and the filter element 53 can be replaced.

[0030] When the utility model is in use, one of the threaded rods 56 is rotated to make one of the water-blocking rods 54 move down to abut against the inner bottom wall of one of the control cylinders 51 and drive one of the connecting frames 57 and the mounting rod 58 to move down, so that one of the mounting rods 58 is snapped into one of the cover plates 514 and the filter cylinder 52, so that one of the control cylinders 51 is in a blocked state; the other threaded rod 56 is rotated to make the other water-blocking rod 54 move up and drive the other connecting frame 57 and the mounting rod 58 to move up, so that the other mounting rod 58 is away from the other cover plate 514 and the filter cylinder 52, so that the other control cylinder 51 is in a unblocked state; at this time, one of the cover plates 514 is pulled to make one of the filter cylinders 52 unblocked, and the filter element 53 that has been used for a period of time can be replaced without shutting down the negative pressure water supply equipment.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
