Technical Field
[0001] The utility model relates to the technical field of nozzle striker bodies, in particular to a nozzle striker structure with durable use. Background Art
[0002] The nozzle striker structure is usually composed of a nozzle, a striker body and a nozzle holder. The nozzle is used to spray liquid or gas, the striker body is used to control the flow of liquid or gas, and the nozzle holder is a bracket used to fix the nozzle and the striker body. This structure is widely used in spraying, cleaning, spraying and other fields, and can accurately control the spray direction and intensity of the nozzle.
[0003] The Chinese patent "A courtyard landscape landscaping impact needle body nozzle" authorization announcement number "CN214974949U" uses a spring and a plastic plug to seal the water outlet channel in the nozzle head, thereby preventing water from flowing back into the pipe, thereby reducing the risk of pipe freezing and cracking.
[0004] The spring and plastic plug prevent water from flowing back into the pipe, causing water to remain in the nozzle head. In cold weather, this may easily lead to the risk of ice forming in the nozzle head, thereby reducing the service life of the nozzle striker structure.
[0005] Therefore, a nozzle striker structure with durable use is proposed to solve the above problems. Utility Model Content
[0006] The purpose of the present invention is to provide a durable nozzle striker structure in order to solve the above-mentioned problem, thereby improving the problem that water retention in the nozzle head cannot be eliminated, which easily leads to the risk of ice formation in the nozzle head in cold weather.
[0007] The utility model achieves the above-mentioned purpose through the following technical solutions: a durable nozzle striker structure, comprising: a connector, the inner wall of the connector is threadedly connected to the nozzle head, the top of the nozzle head is fixedly connected to the striker body, the inner wall of the connector is slidably connected to the filter cartridge; a drainage mechanism, the drainage mechanism for discharging the retained water in the nozzle head is arranged on the surface of the nozzle head; wherein the drainage mechanism comprises a fixed ring fixedly connected to the inner wall of the connector, the inner wall of the fixed ring is slidably connected to a sealing plug, the inner wall of the nozzle head is connected to a drain pipe, the inner top wall of the nozzle head is fixedly connected to a protective cylinder, the surface of the sealing plug is slidably connected to the inner wall of the protective cylinder, and the inner top wall of the protective cylinder is fixedly connected to the opposite end of the top of the sealing plug. The first spring, the fixed ring and the sealing plug are used to prevent the backflow of water in the nozzle head, and the drainage pipe is used to guide and discharge the retained water above the sealing plug, thereby avoiding water retention in the nozzle head, thereby reducing the risk of freezing in the nozzle striker structure and improving the service life of the nozzle striker structure.
[0008] Preferably, the inner wall of the drain pipe is fixedly connected with a control ring, the inner wall of the control ring is slidably connected with a sealing plug, the inner wall of the drain pipe is fixedly connected with a mounting tube, and the surface of the sealing plug is slidably connected to the inner wall of the mounting tube. The sealing plug and the control ring are used to block the drain pipe, block the nozzle striker structure during spraying, and the water in the nozzle striker body is discharged through the drain pipe, ensuring the normal spraying of the nozzle striker structure.
[0009] Preferably, one end of the sealing plug is fixedly connected to a second spring, and the other end of the second spring is fixedly connected to one end of the inner wall of the mounting tube. The second spring is used to ensure that when there is no water pressure in the nozzle head, the control ring is opened smoothly, thereby ensuring that the water in the nozzle head is discharged through the control ring and the drain pipe.
[0010] Preferably, the inner wall of the control ring is fixedly connected to a limit block. The limit block is used to limit the moving range of the sealing plug, preventing the water pressure in the nozzle head from pushing the sealing plug away from the control ring, thereby ensuring the sealing effect of the sealing plug on the control ring.

[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.
[0024] When implementing: Figure 1-4 As shown, a durable nozzle striker structure comprises: a connecting head 1, the inner wall of the connecting head 1 is threadedly connected with a nozzle head 2, the top of the nozzle head 2 is fixedly connected with a striker body 3, the inner wall of the connecting head 1 is slidably connected with a filter cartridge 4; a drainage mechanism 5, the drainage mechanism 5 for discharging retained water in the nozzle head 2 is arranged on the surface of the nozzle head 2; wherein the drainage mechanism 5 comprises a fixing ring 51 fixedly connected to the inner wall of the connecting head 1, the inner wall of the fixing ring 51 is slidably connected with a sealing plug 52, the inner wall of the nozzle head 2 is connected with a drain pipe 53, the inner top wall of the nozzle head 2 is fixedly connected with a protective cylinder 56, the surface of the sealing plug 52 is slidably connected to the inner wall of the protective cylinder 56, the inner top wall of the protective cylinder 56 and the opposite end of the top of the sealing plug 52 are fixedly connected with a first spring 57, the top of the fixing ring 51 forms an angle with the horizontal plane, the top of the sealing plug 52 forms an angle with the horizontal plane, and the lower end of the surface of the drain pipe 53 forms an angle with the horizontal plane.
[0025] The nozzle head 2 and the striker body 3 are both superhard diamond components, and the connector 1 is threadedly connected in the pipeline.
[0026] When the nozzle striker structure is spraying, high-pressure water pressurized by the water pump enters the nozzle head 2 from the connecting head 1, and the water pressure pushes the sealing plug 52 upward to open the fixing ring 51, so that the sprayed high pressure hits the striker body 3 to form atomized particles for spraying. After the water pump stops working, the water remaining in the nozzle head 2 cannot be sprayed out due to lack of pressure. At this time, the elastic force of the first spring 57 pushes the sealing plug 52 downward to seal the fixing ring 51, thereby preventing water from flowing back into the pipe.
[0027] like Figure 4 As shown, the inner wall of the drain pipe 53 is fixedly connected with a control ring 54, the inner wall of the control ring 54 is slidably connected with a sealing plug 55, the inner wall of the drain pipe 53 is fixedly connected with a mounting tube 59, the surface of the sealing plug 55 is slidably connected to the inner wall of the mounting tube 59, one end of the sealing plug 55 is fixedly connected with a second spring 510, and the other end of the second spring 510 is fixedly connected to one end of the inner wall of the mounting tube 59.
[0028] At this time, there is no water pressure resistance in the drain pipe 53, and the elastic force of the second spring 510 pushes the sealing plug 55 to move, so that the control circle 54 is opened smoothly. Because the fixing ring 51 and the top of the sealing plug 52 are inclined, the water above the sealing plug 52 is quickly diverted into the drain pipe 53. Because the drain pipe 53 is inclined, the water in the drain pipe 53 is quickly discharged.
[0029] like Figure 4 As shown, the inner wall of the control circle 54 is fixedly connected to the limit block 511, and the inner wall of the drain pipe 53 is fixedly connected to the filter screen 58. When the water pressure in the nozzle head 2 is relatively high, the water pushes the sealing plug 55 to contact the limit block 511, and the limit block 511 blocks the sealing plug 55 from continuing to move toward the direction close to the installation cylinder 59, thereby blocking the control circle 54.
[0030] When the utility model is in use, when the nozzle striker structure is spraying, the high-pressure water pressurized by the water pump enters the nozzle head 2 from the connecting head 1, and the water pressure pushes the sealing plug 52 to move up, so that the fixing ring 51 is opened smoothly, and the water pushes the sealing plug 55 to contact the limit block 511, and the limit block 511 blocks the sealing plug 55 from continuing to move toward the direction close to the installation cylinder 59, thereby blocking the control circle 54, so that the ejected high pressure hits the striker body 3, forming atomized particles for spraying, and when the water pump stops working, the nozzle head 2 is sprayed. After that, the water remaining in the nozzle head 2 cannot be sprayed out due to lack of pressure. At this time, the elastic force of the first spring 57 pushes the sealing plug 52 to move down to seal the fixing ring 51, blocking the water from flowing back into the pipeline. At this time, the elastic force of the second spring 510 pushes the sealing plug 55 to move, so that the control circle 54 is unobstructed and opened. Because the fixing ring 51 and the top of the sealing plug 52 are inclined, the water above the sealing plug 52 is quickly diverted into the drain pipe 53, and because the drain pipe 53 is inclined, the water in the drain pipe 53 is quickly discharged.
[0031] It should be noted that the connector 1, nozzle head 2, striker body 3, filter cartridge 4 and filter screen 58 in the above description are all relatively mature devices in existing technology applications, and specific models can be selected according to actual needs.
[0032] 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.
