Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, and more specifically to a nozzle structure that can prevent clogging. Background Technology

[0002] A nozzle is a device that controls the flow direction, speed, shape, or atomization effect of a fluid (liquid or gas). It is widely used in industries such as industry, agriculture, environmental protection, fire protection, and medical care. There are many types of nozzles, among which the most commonly used nozzle is the pressure nozzle, which can form a spray through the pressure of the liquid itself. The nozzle also has built-in filter holes to filter the liquid flowing into the nozzle.

[0003] However, if the filter holes of the existing nozzle structure become clogged with impurities due to prolonged use, users often stop their current work, disassemble the nozzle, and clean the filter holes. This process takes a lot of time, and due to the lack of a mechanism to divert the liquid, it is impossible to restore normal operation in a short time, thereby reducing spraying efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a nozzle structure that can prevent clogging, so as to solve the problem in the background art that when the filter hole for filtering impurities is clogged, the lack of a mechanism for diverting the liquid makes it impossible to resume normal operation in a short time, thereby reducing the spraying efficiency.

[0005] This utility model provides the following technical solution: a nozzle structure that can prevent clogging, including a nozzle body, a container body connected to the nozzle body by a thread, a support tube fixedly connected to the bottom end of the nozzle body inside the container body, an outer pipe body provided below the support tube, and a flow-dividing mechanism, valves, a filter mechanism, and a guide mechanism. The flow-dividing mechanism is located between the support tube and the outer pipe body, and the flow-dividing mechanism is provided in two parts, one part of the flow-dividing mechanism is located on the left side of the support tube and the outer pipe body, and the other part of the flow-dividing mechanism is located on the right side of the support tube and the outer pipe body. Two sets of valves are provided, each set of valves is respectively located on the two parts of the flow-dividing mechanism, and the flow-dividing mechanism and the valves can form a flow-dividing channel. The filter mechanism is located on the two parts of the flow-dividing mechanism, and the guide mechanism is located on the two parts of the flow-dividing mechanism, and the filter mechanism and the guide mechanism are detachably rotatably configured.

[0006] Furthermore, the bottom of the outer pipe is connected to a fastening bolt via a threaded connection.

[0007] Furthermore, the diversion mechanism includes a first connecting pipe, a second connecting pipe, a first mounting pipe, an adjusting bolt, and a second mounting pipe. The first connecting pipe is fixedly connected to the bottom left side of the support pipe, and the second connecting pipe is fixedly connected to the outer right side of the support pipe. The first connecting pipe and the second connecting pipe are symmetrically arranged. The bottom of both the first connecting pipe and the second connecting pipe are threadedly connected to the adjusting bolt. The bottom end of the first connecting pipe is connected to the first mounting pipe through the adjusting bolt, and the bottom end of the second connecting pipe is connected to the second mounting pipe through the adjusting bolt.

[0008] Furthermore, in one group, two valves are respectively installed on the outer walls of the first connecting pipe and the first mounting pipe, and in another group, two valves are respectively installed on the outer walls of the second connecting pipe and the second mounting pipe, with one end of each of the first and second mounting pipes fixedly connected to the outer wall of the outer pipe.

[0009] Furthermore, the guiding mechanism includes a guide groove, a rotating groove, and rubber blocks. There are two sets of guide grooves, which are respectively opened at the bottom ends of the first connecting pipe and the second connecting pipe. Each set of guide grooves has two pieces, and the two guide grooves are arranged in a symmetrical annular array. The first connecting pipe and the second connecting pipe are respectively provided with rotating grooves that connect the interiors of the two sets of guide grooves.

[0010] Furthermore, the filtering mechanism includes a connecting plate, filter holes, a pull plate, positioning blocks, irregular grooves, and positioning holes. The connecting plate is rotatably connected to the interior of two guide mechanisms. Several filter holes are opened at the bottom end of the connecting plate, and the filter holes penetrate through the surface of the connecting plate. A pull plate is fixedly connected to the center position of the bottom end of the connecting plate. Two positioning blocks are fixedly connected to the outer wall of the connecting plate. The two positioning blocks are arranged symmetrically in a circular array. An irregular groove is opened at the top end of the positioning block, and a positioning hole communicating with the interior of the irregular groove is opened at the top end of the positioning block.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model filters the liquid flowing into the nozzle body through filter holes. Two sets of valves control the flow between the first connecting pipe, the first mounting pipe, and the external connecting pipe, as well as the flow between the second connecting pipe, the second mounting pipe, and the external connecting pipe. Under normal circumstances, only one side of the external connecting pipe can flow. When one side becomes clogged due to excessive impurities, the flow can be switched to the other side to continue working, thus diverting the liquid flowing into the nozzle body. When the first connecting pipe is clogged, after work, the restriction between the first connecting pipe and the first mounting pipe can be released by adjusting the bolts. The connecting plate can be rotated by pulling the pull plate, causing the positioning block to align with the guide groove. This allows the connecting plate to be pulled out of the guide groove, facilitating the user to clean the filter holes on one side of the connecting plate. The same method can be used to handle the clogged second connecting pipe. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0020] Appendix Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5The present invention will be further described below.

[0021] See attached document Figures 1-5 A nozzle structure designed to prevent clogging includes a nozzle body 1, which is threadedly connected to a container 20. A support tube 2 is fixedly connected to the bottom of the nozzle body 1 inside the container 20. An external connecting tube 3 is located below the support tube 2. The structure also includes a flow-diverting mechanism, valves 7, a filtering mechanism, and a guiding mechanism. The flow-diverting mechanism is located between the support tube 2 and the external connecting tube 3. The flow-diverting mechanism has two parts: one part is located on the left side of the support tube 2 and the external connecting tube 3, and the other part is located on the right side. Two sets of valves 7 are provided, each set located on one of the two flow-diverting mechanisms, and the flow-diverting mechanism and valves 7 can form a flow-diverting channel. The filtering mechanism and the guiding mechanism are located on both flow-diverting mechanisms, and the filtering mechanism and the guiding mechanism are detachably rotatable.

[0022] In this embodiment, the liquid flowing into the nozzle body 1 can be filtered by the filtration mechanism, and the flow of the two diversion mechanisms can be controlled by two sets of valves 7. Under normal circumstances, only one diversion mechanism can flow. When one part is blocked by too many impurities, it can be switched to the other part to continue working. In this way, the liquid flowing into the nozzle body 1 can be diverted. In addition, the filtration mechanism can be disassembled from the diversion mechanism by the guide mechanism, so as to facilitate the user to clean the filtration mechanism and ensure the subsequent filtration effect.

[0023] Specifically, the bottom of the outer pipe 3 is connected to a fastening bolt 4 via a threaded connection.

[0024] In this embodiment, the external pipe 3 can be connected to the external water inlet pipe by tightening the bolt 4.

[0025] Specifically, the diversion mechanism includes a first connecting pipe 5, a second connecting pipe 6, a first mounting pipe 8, an adjusting bolt 9, and a second mounting pipe 19. The first connecting pipe 5 is fixedly connected to the bottom left side of the support pipe 2, and the second connecting pipe 6 is fixedly connected to the right side of the outer wall of the support pipe 2. The first connecting pipe 5 and the second connecting pipe 6 are arranged symmetrically. The bottom of both the first connecting pipe 5 and the second connecting pipe 6 are threadedly connected to the adjusting bolt 9. The bottom end of the first connecting pipe 5 is connected to the first mounting pipe 8 through the adjusting bolt 9, and the bottom end of the second connecting pipe 6 is connected to the second mounting pipe 19 through the adjusting bolt 9.

[0026] In this embodiment, the first connecting pipe 5 and the first mounting pipe 8 form one set of water inlet channels, and the second connecting pipe 6 and the second mounting pipe 19 form another set of water inlet channels.

[0027] Specifically, in one group, two valves 7 are installed on the outer walls of the first connecting pipe 5 and the first mounting pipe 8, respectively. In the other group, two valves 7 are installed on the outer walls of the second connecting pipe 6 and the second mounting pipe 19, respectively. One end of the first mounting pipe 8 and the second mounting pipe 19 are both fixedly connected to the outer wall of the outer pipe 3.

[0028] In this embodiment, two sets of valves 7 control the flow between the first connecting pipe 5 and the first mounting pipe 8 and the external connecting pipe 3, and simultaneously control the flow between the second connecting pipe 6 and the second mounting pipe 19 and the external connecting pipe 3. This ensures that under normal circumstances, only one side of the external connecting pipe 3 can flow. If one side becomes clogged due to excessive impurities, the flow can be switched to the other side to continue working, thus diverting the liquid flowing into the nozzle body 1.

[0029] Specifically, the guiding mechanism includes a guide groove 10, a rotating groove 11, and rubber blocks 12. There are two sets of guide grooves 10, which are respectively opened at the bottom ends of the first connecting pipe 5 and the second connecting pipe 6. Each set of guide grooves 10 has two guide grooves, which are arranged in a symmetrical ring array. The first connecting pipe 5 and the second connecting pipe 6 are respectively provided with rotating grooves 11 that connect the interiors of the two sets of guide grooves 10. Two rubber blocks 12 are fixedly connected inside the rotating groove 11, and the two rubber blocks 12 are arranged in a symmetrical ring array.

[0030] In this embodiment, due to the function of the rubber block 12, the position of the filter mechanism can be restricted, making it convenient to confine the filter mechanism inside the rotating groove 11, and facilitating the filtration of liquid entering the nozzle body 1.

[0031] Specifically, the filtration mechanism includes a connecting plate 13, filter holes 14, a pull plate 15, a positioning block 16, a shaped groove 17, and a positioning hole 18. The connecting plate 13 is rotatably connected to the interior of two guide mechanisms. Several filter holes 14 are opened at the bottom end of the connecting plate 13, and the filter holes 14 penetrate through the surface of the connecting plate 13. A pull plate 15 is fixedly connected at the center of the bottom end of the connecting plate 13. Two positioning blocks 16 are fixedly connected to the outer wall of the connecting plate 13. The two positioning blocks 16 are arranged symmetrically in a ring array. A shaped groove 17 is opened at the top of the positioning block 16, and a positioning hole 18 communicating with the interior of the shaped groove 17 is opened at the top of the positioning block 16.

[0032] In this embodiment, two connecting plates 13 are provided. The positioning blocks 16 on the outer walls of the two connecting plates 13 are rotatably connected to the two rotating grooves 11. Due to the function of the filter holes 14, the liquid flowing into the nozzle body 1 can be filtered, so that impurities in the liquid are blocked at the bottom of the connecting plates 13.

[0033] The working principle and usage process of this utility model are as follows: In the initial state, the valves 7 on the outer walls of the first connecting pipe 5 and the first mounting pipe 8 are open, while the valves 7 on the outer walls of the second connecting pipe 6 and the second mounting pipe 19 are closed. Due to the function of the filter holes 14, the liquid flowing into the nozzle body 1 can be filtered. When too many impurities are filtered out by the filter holes 14 on the outside of the connecting plate 13 in the first connecting pipe 5, causing the filter holes 14 to become clogged, the valves 7 on the outer walls of the first connecting pipe 5 and the first mounting pipe 8 can be closed, while the valves 7 on the outer walls of the second connecting pipe 6 and the second mounting pipe 19 can be opened. This allows for the diversion of the liquid flowing into the nozzle body 1, preventing the user from having to stop the current work to address the clogged nozzle body 1. After work is completed, the adjusting bolt 9 can be rotated. The adjusting bolt 9 is rotated upwards, thus separating it from the first mounting tube 8. Then, the pull plate 15 is rotated, causing the connecting plate 13 to rotate. This causes the positioning hole 18 to press against the rubber block 12, deforming the rubber block 12. Consequently, the connecting plate 13 can separate the positioning hole 18 at the top of the positioning block 16 from the rubber block 12. Under the action of the irregular groove 17, the connecting plate 13 rotates outside the rubber block 12, causing the positioning block 16 to rotate inside the rotating groove 11. When the positioning block 16 rotates to align with the guide groove 10, the connecting plate 13 can be pulled out of the guide groove 10, making it convenient for the user to clean the filter hole 14 on one side of the connecting plate 13. The same method can also be used to deal with the blockage of the second connecting tube 6.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
