Abstract
Description
Technical Field
[0001] This utility model relates to the field of nozzle equipment technology, and in particular to a nozzle that can switch to hydraulic pressure. Background Technology
[0002] In the field of nozzle equipment technology, traditional nozzles typically adopt a single pressure output mode, that is, liquid is directly sprayed out through a fixed pipe, and the pressure is predetermined by the pump or pipeline design. For example, Chinese Patent No. CN209238197U discloses an adjustable flow nozzle, including a nozzle seat, a nozzle valve core inside the nozzle seat, a water inlet pipe on one side of the nozzle valve core, and an anti-clogging device on the nozzle seat. The anti-clogging device includes an expansion port at the outlet of the nozzle valve core, an edge with internal threads around the expansion port, a hollow water spray block threaded to the edge, a filter screen on the inner wall of the edge, a plurality of first water spray holes on the surface of the water spray block, a cover rotatably connected to the outer wall of the water spray block, and a second water spray hole on the cover with the same size as the first water spray holes.
[0003] While this nozzle structure can effectively filter water, reduce clogging of the spray holes, and improve overall service life, and the cleaning rod can effectively clean the inside of the nozzle when needed, the pressure of this nozzle is not adjustable. It cannot dynamically switch between high and low pressure modes according to actual needs, such as different cleaning intensities or irrigation requirements, which limits its application scenarios. Utility Model Content
[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a nozzle that can switch to hydraulic pressure, which can freely select the pressure mode according to the usage scenario.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A nozzle capable of switching to hydraulic pressure includes:
[0007] The inlet pipe has a dual-port fitting at one end, which includes a straight guide pipe, a diversion guide pipe, and a reversing valve. One end of the reversing valve is directly connected to the fitting on the inlet pipe. The straight guide pipe and the diversion guide pipe are respectively connected to the outlet connectors of the reversing valve. The other end of the straight guide pipe is connected to a pressure reducing pipe, and the other end of the pressure reducing pipe is connected to a first spray element. The other end of the diversion guide pipe is connected to a booster pump, and the other end of the booster pump is connected to a second spray element.
[0008] Furthermore, the inner diameter of the pressure reducing pipe is smaller than the inner diameter of the straight guide pipe. After the liquid flows into the pressure reducing pipe from the straight guide pipe, the pressure decreases. A first liquid outlet pipe is provided between the pressure reducing pipe and the first spray element. The first liquid outlet pipe is threadedly fitted to one end of the pressure reducing pipe.
[0009] Furthermore, a second liquid outlet pipe is provided between the booster pump and the second spray component, and the second liquid outlet pipe is sealed and connected to the inside of the booster pump connector.
[0010] Furthermore, the second spray component has the same structure as the first spray component. The structure of the first spray component includes a spray base, an inner spray plate, an outer spray plate, a connecting column, and a limiting cover. The surfaces of the inner and outer spray plates are provided with spray holes. The inner and outer spray plates are disposed on one side of the spray base. The connecting column is fixedly disposed at the center of the inner spray plate. The outer spray plate is sleeved on the outside of the connecting column and is disposed outside the inner spray plate. The limiting cover is disposed at the outer end of the connecting column.
[0011] Furthermore, a fixing frame is provided on the outside of the first spray component and the second spray component, the spray base is disposed in the fixing frame, and a first fixing pipe and a second fixing pipe are disposed inside the fixing frame. The first fixing pipe is connected to one end of the first liquid outlet pipe, and the second fixing pipe is connected to one end of the second liquid outlet pipe.
[0012] Furthermore, an inlet filter is provided at the other end of the inlet pipe. The inlet filter includes a base block and a filter screen. The base block is threaded onto the outside of the inlet pipe, and the filter screen is fixedly disposed inside the base block. The base block covers the inlet port of the inlet pipe.
[0013] In summary, this utility model has the following beneficial effects:
[0014] ① Pressure can be flexibly switched: The liquid flow direction is controlled by the reversing valve, and users can quickly select the low-pressure path or the high-pressure path to achieve seamless switching between high and low pressure modes. In the low-pressure mode, the liquid is output after natural pressure reduction through the pressure reducing pipe, which is suitable for impact-sensitive scenarios such as plant irrigation and precision instrument cleaning. In the high-pressure mode, the liquid is output after being pressurized by the booster pump, which is suitable for high-intensity demand scenarios such as industrial equipment descaling and powerful floor washing.
[0015] ② Compact structure: The integrated design of the double-pipe fitting and the fixed frame simplifies the installation process and saves space. The spray components adopt a detachable threaded assembly method, which facilitates quick replacement or adjustment of the spray angle.
[0016] ③ Adjustable spraying accuracy and coverage: The inner and outer spray discs can be adjusted in relative position through the connecting column and the limiting cover, which can change the spraying angle and coverage to meet different working distance requirements.
[0017] ④ It has a high-efficiency filtration function: the liquid inlet filter effectively intercepts impurities and extends the nozzle life through the threaded assembly of the base block and filter screen. Attached Figure Description

[0025] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figure 1 To be continued Figure 5 The detailed description of the embodiments will make this clear. All structural details mentioned in the following embodiments are based on the accompanying drawings.
[0026] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings. Example
[0027] A nozzle capable of switching to hydraulic pressure includes:
[0028] Liquid inlet pipe 1 serves as the liquid input channel, delivering external liquid into the nozzle structure.
[0029] A liquid inlet filter 13 is installed at one end of the liquid inlet pipe 1. The liquid inlet filter 13 is directly installed at the liquid inlet port of the liquid inlet pipe 1 to filter impurities that may be mixed in the liquid, to ensure the cleanliness of the liquid entering the nozzle structure, and to prevent impurities from clogging subsequent components and affecting the spraying effect of the nozzle.
[0030] Specifically, the liquid inlet filter 13 includes a base block 1301 and a filter screen 1302. The base block 1301 is threaded onto the outside of the liquid inlet pipe 1, and the filter screen 1302 is fixedly disposed inside the base block 1301. The base block 1301 covers the liquid inlet port of the liquid inlet pipe 1.
[0031] The other end of the inlet pipe 1 is provided with a double-pass fitting, which includes a straight guide pipe 2, a diversion guide pipe 3, and a reversing valve 4. One end of the reversing valve 4 is directly connected to the fitting of the inlet pipe 1. The straight guide pipe 2 and the diversion guide pipe 3 are respectively connected to the outlet ends of the reversing valve 4. The other end of the straight guide pipe 2 is connected to a pressure reducing pipe 5. The other end of the pressure reducing pipe 5 is provided with a first spray element. The other end of the diversion guide pipe 3 is connected to a booster pump 6. The other end of the booster pump 6 is provided with a second spray element.
[0032] The inner diameter of the pressure reducing pipe 5 is smaller than that of the straight guide pipe 2. After the liquid flows into the pressure reducing pipe 5 from the straight guide pipe 2, the pressure decreases. A first liquid outlet pipe 7 is provided between the pressure reducing pipe 5 and the first spray element. The first liquid outlet pipe 7 is threaded onto one end of the pressure reducing pipe 5. The pressure reducing pipe 5 is used to reduce the liquid pressure and realize low-pressure spraying. Since the diameter of the pressure reducing pipe 5 is smaller than that of the straight guide pipe 2, the pressure decreases due to the sudden change in pipe diameter when the liquid flows through it. The low-pressure liquid is transported to the first spray element through the first liquid outlet pipe 7.
[0033] A second liquid outlet pipe 8 is provided between the booster pump 6 and the second spray component. The second liquid outlet pipe 8 is sealed and connected to the connector of the booster pump 6. The booster pump 6 is used to increase the liquid pressure to achieve high-pressure spraying. The liquid enters the booster pump 6 for pressurization through the diversion guide pipe 3. The high-pressure liquid is transported to the second spray component through the second liquid outlet pipe 8.
[0034] The reversing valve 4 is the core control component, used to switch the liquid flow to either the straight guide pipe 2 or the diversion guide pipe 3. In the two liquid paths, the straight guide pipe 2 is connected to the pressure reducing pipe 5, which directly delivers the liquid to the first spray element. This path is a low-pressure path. The diversion guide pipe 3 is connected to the booster pump 6, which guides the liquid to the second spray element. This path is a high-pressure path. The user selects the liquid path by operating the reversing valve 4. When the liquid enters the straight guide pipe 2, it is not pressurized. Instead, the water pressure gradually decreases due to the small inner diameter of the pressure reducing pipe 5. When it enters the diversion guide pipe 3, the liquid booster pump 6 pressurizes the water pressure, thus achieving flexible switching between high and low pressure modes to adapt to different scenario requirements. The low-pressure mode is suitable for scenarios that are sensitive to liquid impact, while the high-pressure mode is suitable for scenarios that require strong impact.
[0035] The second spray component has the same structure as the first spray component. The structure of the first spray component includes a spray base 901, an inner spray plate 902, an outer spray plate 903, a connecting post 904, and a limiting cover 905. Spray holes 906 are provided on the surfaces of the inner spray plate 902 and the outer spray plate 903. The inner spray plate 902 and the outer spray plate 903 are located on one side of the spray base 901. The connecting post 904 is fixedly located at the center of the inner spray plate 902. The outer spray plate 903 is sleeved on the outside of the connecting post 904 and is located outside the inner spray plate 902. The limiting cover 905 is located at the outer end of the connecting post 904.
[0036] The double-layer structure consisting of the inner spray plate 902 and the outer spray plate 903 can effectively control the liquid spraying pattern and range. Both the inner spray plate 902 and the outer spray plate 903 are provided with spray holes 906. The liquid forms an atomization or spraying effect through the holes. The outer spray plate 903 is sleeved on the outside of the inner spray plate 902. By rotating it outside the connecting column 904, the relative position with the inner spray plate 902 can be adjusted to change the spraying angle. The double-layer plate design can adjust the spraying coverage range to adapt to different working distances and area requirements.
[0037] The first and second spray components are provided with a fixing frame 10 on their exteriors. The spray base 901 is located in the fixing frame 10. The fixing frame 10 is provided with a first fixing pipe 11 and a second fixing pipe 12. The first fixing pipe 11 is connected to one end of the first liquid outlet pipe 7, and the second fixing pipe 12 is connected to one end of the second liquid outlet pipe 8.
[0038] The above description is a further detailed explanation of the present utility model in conjunction with specific embodiments, and it should not be considered that the specific implementation of the present utility model is limited to this. For those skilled in the art to which the present utility model pertains and related fields, any extensions, operation methods, and data substitutions made based on the technical solution concept of the present utility model should fall within the protection scope of the present utility model.
