[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] Please see the appendix Figure 1 The detachable negative pressure filtration device of this utility model includes a device cavity 100, a liquid inlet assembly 200 detachably mounted on the top of the device cavity 100, a filter assembly 300 detachably connected to the liquid inlet assembly 200 and disposed within the device cavity 100, and a liquid outlet assembly 400 detachably mounted on the bottom of the device cavity 100. The device cavity 100 is used to achieve overall sealing of the device and storage of the filtered liquid; the liquid inlet assembly 200 is used to transport the liquid to be filtered into the device cavity 100; the filter assembly 300 is used to filter impurities in the liquid so that the filtered liquid meets usage requirements; and the liquid outlet assembly 400 is used to output the filtered liquid from the device cavity 100.

[0037] The detachable negative pressure filtration device of this embodiment is assembled from a device cavity 100, an inlet component 200, a filter component 300, and an outlet component 400, all of which are detachable. When a part of the device is damaged, the damaged part can be disassembled separately for repair or replacement. This not only effectively reduces the difficulty of overall device maintenance, but also effectively reduces the overall cost of use and extends the overall service life of the device compared to equipment that needs to be scrapped after damage.

[0038] Please refer to the appendix for further details. Figure 2In some embodiments, the liquid inlet assembly 200 includes a detachable liquid inlet mounting base 210 mounted on the top of the device cavity 100, a liquid inlet pipe 220 communicating with the liquid inlet mounting base 210 for conveying the liquid to be filtered, and a liquid inlet sealing ring 230 disposed between the liquid inlet mounting base 210 and the device cavity 100 to improve the overall sealing of the device. Preferably, the liquid inlet mounting base 210 is mounted on the device cavity 100 by means of screw connection, and the liquid inlet mounting base 210 is made of PVC material. Further, the liquid inlet mounting base 210 includes a mounting base body 211 and a mounting limiting groove 212 disposed on the mounting base body 211 for mounting and connecting the filter assembly 300, as shown in the attached figure. Figure 3 As shown.

[0039] Please refer to the appendix for further details. Figure 2 In some embodiments, the liquid dispensing assembly 400 includes a detachable liquid dispensing mounting base 410 installed at the bottom of the device cavity 100, a liquid dispensing pipe 420 communicating with the liquid dispensing mounting base 410 for discharging filtered liquid, and a liquid dispensing sealing ring 430 disposed between the liquid dispensing mounting base 410 and the device cavity 100 for improving the overall sealing of the device; preferably, the liquid dispensing mounting base 410 is made of PVC material.

[0040] Please refer to the appendix for further details. Figure 4 In some embodiments, the filter assembly 300 includes a filter frame 310 detachably connected to the liquid inlet mounting base 210 in the liquid inlet assembly 200 and disposed within the device cavity 100, and a filter screen 320 disposed at the bottom of the filter frame 310. Preferably, the filter screen 320 is a unidirectional filter structure with a higher side adjacent to the liquid inlet assembly 200 and a lower side away from the liquid inlet assembly 200. This not only effectively increases the filtration area within a certain space and improves the overall filtration efficiency of the device, but also allows the filtered impurities to accumulate on the lower side of the filter screen 320, facilitating the discharge of impurities. More preferably, the filter screen 320 is an arc-shaped unidirectional filter structure with a higher side adjacent to the liquid inlet assembly 200 and a lower side away from the liquid inlet assembly 200, bulging towards the liquid inlet assembly 200. Compared to a straight filter structure, the arc-shaped filter structure can effectively slow down the flow rate of the liquid to be filtered, further increasing the filtration area of ​​the filter screen 320, thereby further effectively ensuring the overall filtration efficiency of the device.

[0041] In addition, in terms of materials, the filter assembly 300 is preferably made of stainless steel, which can effectively improve the overall strength and stability of the assembly, extend the overall service life of the assembly, and reduce the probability of overall device maintenance.

[0042] Please refer to the appendix for further details. Figure 5The filter frame 310 includes a filter frame body 311 that is detachably connected to the liquid inlet mounting seat 210 in the liquid inlet assembly 200, a filter liquid inlet 312 that is connected to the liquid inlet pipe 220 in the liquid inlet assembly 200 and opened on the top of the filter frame body 311, a liquid inlet baffle 313 that corresponds to the filter liquid inlet 312 and is disposed on the filter frame body 311, and a drain outlet 314 that is connected to the bottom of the filter screen 320 and disposed at the bottom of the filter frame body 311. The filter frame body 311 is used to install and connect the filter assembly 300 as a whole. Preferably, for the installation and disassembly of the filter frame 310 as a whole, the top two sides of the filter frame body 311 are provided with lifting holes 316, so that the space above the lifting holes 316 of the filter frame body 311 can form a lifting handle structure. The filter inlet 312 is used to allow the liquid to be filtered to enter. The liquid inlet baffle 313 is used to initially filter large-area impurities in the liquid to prevent large-area impurities such as fallen leaves and stones from entering the device cavity 100. The drain port 314 is used to discharge the impurities after filtration to prevent the overall filtration efficiency of the device from being affected by the blockage of impurities, and effectively extend the service life of the device.

[0043] During installation, simply insert the filter frame body 311 into the installation limiting groove 212 of the liquid inlet mounting seat 210 to achieve the overall installation and connection of the filter assembly 300. During disassembly, simply pull it upwards through the lifting hole 316 to disassemble the filter assembly 300. The filter assembly 300 is not only easy and quick to install and disassemble, which can effectively improve the overall installation and maintenance efficiency of the device, but also the method of completing the overall installation and limiting of the filter frame 310 through the liquid inlet mounting seat 210 in the liquid inlet assembly 200 can effectively improve the stability of the assembly between the filter assembly 300 and the liquid inlet assembly 200, ensuring that the liquid can be accurately delivered to the filter inlet 312 after passing through the liquid inlet pipe 220, thereby improving the overall filtration efficiency of the device.

[0044] Please see the appendix Figure 4 and 5In some embodiments, the filter frame 310 further includes a guide plate 315 corresponding to the top of the liquid inlet baffle 313 and detachably installed inside the filter frame body 311; further, the guide plate 315 is an arc-shaped guide plate structure with its center point located on one side adjacent to the liquid inlet baffle 313; preferably, the guide plate 315 is an elastic PC plate. When the liquid to be filtered flows through the filter inlet 312 and enters the device cavity 100 from the top of the liquid inlet baffle 313, the guide plate 315 can guide the liquid to be filtered, conveying the liquid to be filtered to the side adjacent to the filter inlet 312. This is adapted to the structure of the filter screen 320, which is higher on the side adjacent to the liquid inlet component 200 and lower on the side away from the liquid inlet component 200, so that the liquid to be filtered can be conveyed from the higher side to the lower side of the filter screen 320, completing the filtration of the liquid. This not only further improves the overall filtration effect of the device, but also effectively prevents the filtered liquid from flowing directly to the drain outlet 314 and causing blockage of the drain outlet 314.

[0045] Please see the appendix Figure 1 and 2 In some embodiments, the detachable negative pressure filter further includes a drain assembly 500, which is connected to the bottom of the filter assembly 300 and detachably installed at the bottom of the device cavity 100. Further, the drain assembly 500 includes a drain mounting base 510 detachably installed at the bottom of the device cavity 100, a first drain pipe 520 connected to the drain port 314 in the filter assembly 300 and installed on the drain mounting base 510, a second drain pipe 530 connected to the outside of the device cavity 100 and installed on the drain mounting base 510, and a drain sealing ring 540 disposed between the drain mounting base 510 and the device cavity 100 to improve the overall sealing of the device. Preferably, the drain mounting base 510 is made of PVC. When impurities accumulate in the filter assembly 300 to a certain amount or after the device has been used for a period of time, the device cavity 100 can be opened to clean the inside of the filter assembly 300, allowing the impurities to be discharged from the device, thus ensuring the overall filtration effect of the device.

[0046] Please see the appendix Figure 1In some embodiments, the device cavity 100 includes a device cavity body 110, a cavity top cover 120 detachably mounted on the top of the device cavity body 110, and a top cover sealing ring 130 disposed on the cavity top cover 120 for achieving overall sealing of the device cavity 100. Preferably, the cavity top cover 120 is mounted on the top of the device cavity body 110 via a snap-fit ​​connection. When the filter assembly 300 inside the device cavity 100 needs maintenance or cleaning, the cavity top cover 120 can be quickly opened to allow for maintenance or cleaning of the filter assembly 300, effectively improving the overall maintenance and usage efficiency of the device. More preferably, both the device cavity body 110 and the cavity top cover 120 are made of PC material, which not only has good sealing performance and strength, but also effectively reduces the overall weight of the device compared to steel, facilitating the transfer of the device.

[0047] As can be seen from the technical solutions of the above embodiments, the present invention provides a detachable negative pressure filtration device, which is assembled from a device cavity, an inlet component, a filter component and an outlet component, each of which can be freely disassembled. When a part of the device is damaged, the damaged part can be disassembled separately for repair or replacement. This not only effectively reduces the difficulty of overall device maintenance, but also effectively reduces the overall cost of the device and extends its service life compared to equipment that needs to be scrapped after damage.
