Description

Technical Field

[0001] The invention relates to the technical field of atomizing devices, in particular to an active pressurized adjustable nozzle anti-blocking type sprayer. Background Art

[0002] In various spraying operation scenarios, such as agricultural plant protection, garden irrigation, industrial spraying, and daily cleaning and disinfection, sprayers play an indispensable role. Their working stability and operating efficiency directly affect the quality of pesticide application.

[0003] At present, mainstream electric sprayers generally have filter elements and other structures to avoid nozzle clogging. For example, the patents "CN221386956U, an anti-clogging electric sprayer" and "CN119056608A, an electric sprayer with nozzle self-cleaning and anti-clogging function" each disclose a technical solution to prevent nozzle clogging. However, when working with high-concentration liquid medicine, once the filter element is blocked, the staff usually needs to stop working first, and then use backwashing and other means to clean the filter element. This technical means is not conducive to the continuity of the operation and can easily cause the loss of effective working time. Finally, mainstream electric sprayers generally use a single liquid pump power system to achieve liquid medicine pressurization and injection functions. At the same time, the stirring mechanism inside the sprayer is also mostly driven by an independent motor. In this design, the liquid pump is a single power source. Once a failure occurs, it will cause the entire system to shut down, which is not conducive to improving the working reliability of the sprayer. In addition, the amplitude of the pressurization through the single liquid pump is very limited. If the amplitude of the pressurization is too large, it is easy to affect the life of the liquid pump. Summary of the invention

[0004] The object of the present invention is to provide an active pressure-boosting adjustable nozzle anti-clogging type sprayer to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an active pressurized adjustable nozzle anti-clogging sprayer, comprising a barrel body, a spray rod and a handle, the spray rod being installed on the handle, a nozzle being installed at the output end of the spray rod, a purification seat being provided at one end of the handle away from the spray rod, a filter chamber and a filter assembly being provided in the purification seat, a waste liquid tank being provided outside the purification seat, a sealing assembly being provided in the waste liquid tank, the waste liquid tank being connected to the filter chamber, a first liquid pump, a second liquid pump and a three-way pipe being provided at the lower end of the barrel body, medicine and water need to be poured into the upper end of the barrel body during operation, one end of the three-way pipe being connected to the purification seat through a delivery pipe, and the other two ends of the three-way pipe being respectively connected to the first liquid pump and the second liquid pump.

[0006] In the normal spraying operation of the present invention, the first liquid pump is in a shutdown state, and the second liquid pump is in an open state. The liquid medicine in the barrel body is transported to the three-way pipe by the second liquid pump. At this time, the liquid medicine will flow along the three-way pipe, the delivery pipe, the filter chamber, the filter assembly, the handle, and the spray rod, and then sprayed out from the nozzle. The impurity particles in the liquid medicine are intercepted by the filter assembly to avoid clogging of the nozzle. If the range and efficiency need to be improved during the spraying operation, the staff can directly turn on the first liquid pump. The coordinated work of the first liquid pump and the second liquid pump can effectively improve the output pressure of the liquid medicine. Compared with the current sprayer pressurization method, the present invention can increase the system flow while pressurizing on the one hand, and the first liquid pump and the second liquid pump can be replaced with each other on the other hand. If one liquid pump fails, the other liquid pump can continue to work, thereby improving the reliability of the overall system. Finally, the present invention is provided with a waste liquid tank on the outside of the purification seat. Through the mutual cooperation of the sealing assembly in the waste liquid tank and the filter assembly, the present invention can achieve the effect of cleaning the filter assembly while spraying, thereby improving the continuity of the operation and reducing the downtime for maintenance.

[0007] Furthermore, the three-way pipe is connected to the first liquid pump through a first one-way valve and a guide box, and the three-way pipe is connected to the second liquid pump through a second one-way valve. The first one-way valve and the second one-way valve ensure that the liquid medicine discharged from the first liquid pump and the second liquid pump will enter the output end of the three-way pipe to prevent the liquid medicine from flowing back.

[0008] Furthermore, one end of the filter chamber is connected to the delivery pipe through a liquid inlet channel, and the other end of the filter chamber is connected to the handle through a liquid discharge channel. An alarm system is arranged on the outside of the handle, and a pressure detection element is arranged on the side wall of the liquid inlet channel. The pressure detection element is connected to the alarm system. During the spraying operation of the present invention, the medicine liquid will flow along the liquid inlet channel, the filter assembly, and the liquid discharge channel after entering the purification seat. When the filter assembly is blocked, so that the medicine liquid cannot flow smoothly, the pressure in the liquid inlet channel will increase. At this time, the first pressure detection element will transmit a set of signals to the alarm system, so that the alarm system can promptly prompt the staff to clean the filter assembly.

[0009] Furthermore, the filter assembly includes a filter frame, which is provided with four groups of mounting holes, each group of mounting holes is provided with a group of filter screens, and a first rotating rod is provided at the side end of the filter frame, one end of the first rotating rod extends out of the purification seat, and the filter frame is controlled to rotate in the filter chamber by the first rotating rod.

[0010] Furthermore, the filter chamber is connected to the waste liquid tank through a waste hole, and the sealing assembly includes a second rotary rod, and a sealing block is provided at one end of the second rotary rod close to the waste hole. The second rotary rod is connected to the waste liquid tank through a threaded connection. During the normal operation of the sprayer, there is always a group of filter screens on the filter frame that are aligned with the liquid inlet channel, and the liquid medicine is filtered through a group of filter screens close to the liquid inlet channel. At the same time, the sealing block is always located in the waste hole, and the filter chamber is separated from the waste liquid tank through the waste hole, so as to prevent clean liquid medicine from flowing into the waste liquid tank. When a group of filter screens close to the liquid inlet channel needs to be cleaned due to blockage, the staff can rotate the filter frame through the first rotary rod to allow the filter screens to be cleaned to pass through the filter frame. The first liquid pump is turned on simultaneously as needed when cleaning the filter screen, so as to increase the output pressure of the liquid medicine, so as to avoid the pressure of the liquid medicine sprayed from the nozzle not meeting the standard when the filter screen is being cleaned, resulting in changes in the range and coverage area. When the filter screen is cleaned, the staff can rotate the second rotary rod to make the sealing block block the waste hole again.

[0011] Furthermore, a positioning groove is provided at one end of the purification seat close to the first rotating rod, four groups of limiting components are provided on the inner wall of the positioning groove, and a positioning block is provided on the outer side of one end of the filter frame located in the positioning groove, and the filter component is limited by the cooperation of the four groups of limiting components and the positioning block.

[0012] Furthermore, each set of limiting components includes two protrusions, which are elastic. One end of the positioning block close to the inner wall of the positioning groove is an arc-shaped structure. During the spraying process, the positioning block is always located in one of the sets of limiting components (i.e., between the two protrusions). The positioning block is limited by the limiting component (two protrusions) to avoid the position displacement of the filter component in the filter chamber due to the impact of the liquid medicine. Finally, when the staff rotates the filter component to change the position of the four sets of filter screens, the positioning block will overcome the resistance of the limiting component (two protrusions) to the positioning block under the action of manpower and enter into another limiting component (two protrusions). At this time, the staff can judge the position of the positioning block by overcoming the change in the size of the resistance, thereby indirectly knowing the position change of the four sets of filter screens to ensure that the filter screen to be cleaned is aligned with the waste hole.

[0013] Furthermore, a support seat and a fixed seat are provided at the lower end of the interior of the barrel body, a circulation pipe and a stirring rod are provided at the upper end of the interior of the barrel body, a drainage chamber and a transmission assembly are provided in the fixed seat, the circulation pipe is connected with the outlet end of the drainage chamber, the guide box is connected with the inlet end of the drainage chamber through a connecting pipe, the lower end of the stirring rod passes through the support seat, the transmission assembly is connected with the stirring rod through a first gear and a second gear, and a reversing assembly is provided in the guide box. Before the spraying operation of the present invention, the staff needs to pour the medicine and water into the upper end of the interior of the barrel body, and then control the connection between the guide box and the connecting pipe through the reversing assembly, and then start the first liquid pump, and transport the medicine liquid in the barrel body to the guide box through the first liquid pump. At this time, the medicine liquid will flow along the connecting pipe, the drainage chamber and the circulation pipe, and the medicine liquid will flow along the connecting pipe, the drainage chamber and the circulation pipe. During the flow process, a group of forces will be applied to the transmission component. At this time, the transmission component drives the stirring rod to rotate through the first gear and the second gear, and stirs the medicine liquid in the barrel through the stirring rod to ensure that the medicine and water are completely mixed. When the mixing is completed and spraying is required, the staff can control the diversion box to be connected to the three-way pipe through the reversing component to ensure that the subsequent first liquid pump and the second liquid pump can work together, thereby increasing the output pressure and flow rate of the medicine liquid. Finally, compared with the current sprayer, the first liquid pump in the present invention is used as a power source for pressurizing the medicine liquid on the one hand, and as a backup power source when the second liquid pump fails on the other hand, as well as a power source for the stirring rod to stir the medicine liquid. Through the above technical scheme, the present invention can greatly reduce the manufacturing cost, while making full use of energy and improving work efficiency.

[0014] Furthermore, the transmission assembly includes fan blades and a fixed frame, the fixed frame is arranged in the middle position of the drainage chamber, the fan blades are arranged at one end of the fixed frame close to the circulation tube, and the fan blades are connected to the second gear through a transmission shaft. When the medicine flows in the drainage chamber, the fan blades will rotate with the second gear, and the stirring rod will rotate synchronously through the second gear and the first gear, thereby achieving the purpose of mixing the medicine and water.

[0015] Furthermore, the reversing component includes a diverter plate, a first through hole is provided at one end of the diverter plate close to the connecting pipe, a second through hole is provided at one end of the diverter plate close to the three-way pipe, a baffle and an electromagnet are provided in the diverter plate, a third through hole is provided on the baffle plate, and a permanent magnet is inlaid on one end of the baffle plate close to the electromagnet. The present invention controls the movement of the baffle in the diverter plate through the electromagnet. When the electromagnet generates a set of magnetic fields that repel the permanent magnet, the baffle moves away from the electromagnet. At this time, the third through hole on the baffle is aligned with the first through hole on the diverter plate, and the guide box is connected to the connecting pipe. When the electromagnet generates a set of magnetic fields that attract the permanent magnet, the baffle approaches the electromagnet, the baffle blocks the first through hole on the diverter plate, and the second through hole on the diverter plate is in an open state. At this time, the guide box is connected to the three-way pipe. The present invention can control the flow direction of the liquid in the guide box in real time as needed through the electromagnet and the baffle to ensure the normal operation of pressurization, stirring and the like.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: compared with the current sprayer, the present invention is provided with a first liquid pump and a second liquid pump, and the first liquid pump and the second liquid pump can be replaced with each other. If one liquid pump fails, the other liquid pump can continue to work, thereby improving the reliability of the overall system. In addition, the first liquid pump in the present invention, on the one hand, serves as a power source for pressurizing the liquid medicine, ensuring that the liquid medicine is pressurized while increasing the system flow rate. On the other hand, the first liquid pump is also a power source for the stirring rod to stir the liquid medicine, thereby ensuring that the medicine and water in the barrel are completely mixed before the spraying operation. The present invention can reduce the manufacturing cost and improve the work efficiency while meeting the requirements of pressurization, stirring and reliability through the mutual cooperation of the first liquid pump and the second liquid pump. The present invention is also provided with a purification seat and a waste liquid tank. The impurity particles in the liquid medicine are intercepted by the filter component in the purification seat to avoid clogging of the nozzle. When the filter component is clogged, the sealing component in the waste liquid tank cooperates with the filter component, and the present invention can achieve the effect of cleaning the filter component while spraying, thereby improving the continuity of the operation and reducing the downtime for maintenance.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example: Figure 1-Figure 11 As shown, the present invention provides a technical solution, an active boost adjustable nozzle anti-blocking sprayer, comprising a barrel body 1, a spray rod 2 and a handle 3, the spray rod 2 is installed on the handle 3, the output end of the spray rod 2 is installed with a nozzle, the end of the handle 3 away from the spray rod 2 is provided with a purification seat 4, the purification seat 4 is provided with a filter cavity and a filter assembly 46, the outside of the purification seat 4 is provided with a waste liquid tank 42, the waste liquid tank 42 is provided with a sealing assembly, the waste liquid tank 42 is connected with the filter cavity, the lower end of the barrel body 1 is provided with a first liquid pump 13, a second liquid pump 14 and a three-way pipe 15, the upper end of the barrel body 1 needs to be poured with medicine and water when working, one end of the three-way pipe 15 is connected with the purification seat 4 through a delivery pipe 5, the other end of the three-way pipe 15 is connected with the first liquid pump 13 through a first one-way valve and a guide box 7, and the last end of the three-way pipe 15 is connected with the second liquid pump 14 through a second one-way valve.

[0021] In the present invention, when the spraying is in normal operation, the first liquid pump 13 is in a stopped state, and the second liquid pump 14 is in an opened state. The liquid medicine in the barrel body 1 is transported to the three-way pipe 15 through the second liquid pump 14. At this time, the liquid medicine flows along the three-way pipe 15, the delivery pipe 5, the filter cavity, the filter assembly 46, the handle 3, and the spray rod 2, and then is sprayed out from the nozzle. The impurity particles in the liquid medicine are intercepted by the filter assembly 46 to avoid clogging of the nozzle. If the spraying work needs to improve the range and efficiency, the staff can directly start the first liquid pump 13, and the coordinated work of the first liquid pump 13 and the second liquid pump 14 can effectively improve the spraying range and efficiency. The output pressure of the high-pressure liquid medicine is compared with the current sprayer boosting method. On the one hand, the present invention can increase the system flow while boosting the pressure. On the other hand, the first liquid pump 13 and the second liquid pump 14 can be replaced with each other. If one liquid pump fails, the other liquid pump can continue to work, thereby improving the reliability of the overall system. Finally, the present invention is provided with a waste liquid tank 42 on the outside of the purification seat 4. Through the mutual cooperation of the sealing component in the waste liquid tank 42 and the filter component 46, the present invention can achieve the effect of cleaning by spraying and filtering the component 46 at the same time, thereby improving the continuity of the operation and reducing the downtime for maintenance.

[0022] like Figure 4 and Figure 5 As shown, one end of the filter chamber is connected to the delivery pipe 5 through the liquid inlet channel 45, and the other end of the filter chamber is connected to the handle 3 through the liquid discharge channel 44. An alarm system is arranged on the outside of the handle 3, and a pressure detection element is arranged on the side wall of the liquid inlet channel 45. The pressure detection element is connected to the alarm system. In the spraying process of the present invention, after the liquid medicine enters the purification seat 4, it will flow along the liquid inlet channel 45, the filter component 46, and the liquid discharge channel 44. When the filter component 46 is blocked, so that the liquid medicine cannot flow smoothly, the pressure in the liquid inlet channel 45 will increase. At this time, the first pressure detection element will transmit a set of signals to the alarm system, so that the alarm system can promptly remind the staff to clean the filter component 46.

[0023] like Figure 5-Figure 7 As shown, the filter assembly 46 includes a filter frame 461, which is provided with four groups of mounting holes, each group of mounting holes is provided with a group of filter screens 462, and a first rotating rod 41 is provided at the side end of the filter frame 461, one end of the first rotating rod 41 extends out of the purification seat 4, and the filter frame 461 is controlled to rotate in the filter cavity by the first rotating rod 41.

[0024] like Figure 5 As shown, the filter chamber is connected to the waste liquid tank 42 through a waste hole, and the sealing assembly includes a second rotary rod 43. A sealing block 431 is provided at one end of the second rotary rod 43 close to the waste hole. The second rotary rod 43 is connected to the waste liquid tank 42 through a threaded connection.

[0025] During the normal operation of the sprayer, there is always a group of filter screens 462 on the filter frame 461 that is aligned with the liquid inlet channel 45. The liquid medicine is filtered through the group of filter screens 462 close to the liquid inlet channel 45. At the same time, the sealing block 431 is always located in the waste hole, and the filter cavity is separated from the waste liquid tank 42 through the waste hole, so as to prevent the clean liquid medicine from flowing into the waste liquid tank 42. When the group of filter screens 462 close to the liquid inlet channel 45 needs to be cleaned due to blockage, the staff can rotate the filter frame 461 through the first rotating rod 41 to make the group of filter screens 462 to be cleaned close to the waste hole, and then the staff can rotate the second rotating rod 43 to make the sealing block 431 Leaving the waste hole and entering the waste liquid tank 42, the filter chamber is connected with the waste liquid tank 42 at this time, and the medicine in the filter chamber will pass through the waste hole and flow into the waste liquid tank 42. During the flow, the medicine will flush and clean a group of filter screens 462 to be cleaned. Finally, when cleaning the filter screen 462, the present invention can simultaneously start the first liquid pump 13 as needed to increase the output pressure of the medicine liquid to avoid the pressure of the medicine liquid sprayed from the nozzle not meeting the standard when the filter screen 462 is being cleaned, resulting in changes in the range and coverage area. When the filter screen 462 is cleaned, the staff can rotate the second rotary rod 43 to allow the sealing block 431 to block the waste hole again.

[0026] like Figure 7-Figure 8 As shown, a positioning groove 47 is provided at one end of the purification seat 4 close to the first rotating rod 41 , four groups of limiting components are provided on the inner wall of the positioning groove 47 , and a positioning block 463 is provided on the outer side of one end of the filter frame 461 located in the positioning groove 47 .

[0027] like Figure 7-Figure 8 As shown, each set of limiting components includes two protrusions 471, the protrusions 471 are elastic, and one end of the positioning block 463 close to the inner wall of the positioning groove 47 is an arc structure.

[0028] During the spraying operation, the positioning block 463 is always located in one of the groups of limiting components (i.e., between the two protrusions 471), and the positioning block 463 is limited by the limiting component (two protrusions 471) to prevent the filter component 46 from being displaced in the filter chamber due to the impact of the liquid medicine. Finally, when the staff rotates the filter component 46 to change the position of the four groups of filter screens 462, the positioning block 463 will overcome the resistance of the limiting component (two protrusions 471) to the positioning block 463 under the action of manpower, and enter into another limiting component (two protrusions 471). At this time, the staff can determine the position of the positioning block 463 by overcoming the change in the size of the resistance, thereby indirectly knowing the position change of the four groups of filter screens 462, and ensuring that the filter screen 462 to be cleaned is aligned with the waste hole.

[0029] like Figure 2-Figure 3 , Figure 9-11As shown, a support seat 121 and a fixed seat 6 are also provided at the lower end of the interior of the barrel body 1, a circulation pipe 11 and a stirring rod 12 are provided at the upper end of the interior of the barrel body 1, a drainage chamber 62 and a transmission assembly are provided in the fixed seat 6, the circulation pipe 11 is connected with the outlet end of the drainage chamber 62, the guide box 7 is connected with the inlet end of the drainage chamber 62 through the connecting pipe 71, the lower end of the stirring rod 12 passes through the support seat 121, the transmission assembly is connected with the stirring rod 12 through the first gear 122 and the second gear 61, and a reversing assembly is provided in the guide box 7.

[0030] like Fig.11 As shown, the transmission assembly includes a fan blade 63 and a fixing frame 64. The fixing frame 64 is arranged at the middle position of the drainage chamber 62. The fan blade 63 is arranged at one end of the fixing frame 64 close to the circulation pipe 11. The fan blade 63 is connected to the second gear 61 through a transmission shaft.

[0031] Before the spraying operation of the present invention, the staff needs to pour the medicine and water into the upper end of the barrel body 1, and then control the flow guide box 7 to communicate with the connecting pipe 71 through the reversing component, and then turn on the first liquid pump 13, and the liquid medicine in the barrel body 1 is transported to the flow guide box 7 through the first liquid pump 13. At this time, the liquid medicine will flow along the connecting pipe 71, the drainage cavity 62 and the circulation pipe 11. During the flow, the liquid medicine will exert a group of forces on the fan blades 63. At this time, the fan blades 63 will rotate with the second gear 61. Since the first gear 122 is meshed with the second gear 61, the first gear 122 and the stirring rod 12 will rotate synchronously, and the liquid medicine in the barrel body 1 is stirred by the stirring rod 12. Stirring is performed to ensure that the medicine and water are completely mixed. When the mixing is completed and spraying is required, the staff can control the guide box 7 to be connected to the three-way pipe 15 through the reversing component to ensure that the subsequent first liquid pump 13 and the second liquid pump 14 can work together, thereby increasing the output pressure and flow rate of the liquid medicine. Finally, compared with the current sprayer, the first liquid pump 13 in the present invention is used as a power source for pressurizing the liquid medicine on the one hand, and as a backup power source when the second liquid pump 14 fails on the other hand, as well as a power source for the stirring rod 12 to stir the liquid medicine. Through the above technical scheme, the present invention can greatly reduce the manufacturing cost, while making full use of energy and improving work efficiency.

[0032] like Fig. 9As shown, the reversing assembly includes a diverter plate 72, a first through hole is provided at one end of the diverter plate 72 close to the connecting pipe 71, a second through hole is provided at one end of the diverter plate 72 close to the three-way pipe 15, a baffle 721 and an electromagnet 722 are provided in the diverter plate 72, a third through hole is provided on the baffle 721, and a permanent magnet is embedded at one end of the baffle 721 close to the electromagnet 722. The present invention controls the baffle 721 to move in the diverter plate 72 by the electromagnet 722. When the electromagnet 722 generates a set of magnetic fields that repel the permanent magnet, the baffle 721 moves away from the electromagnet 722. At this time, the baffle 721 moves away from the electromagnet 722. The third through hole on the plate 721 is aligned with the first through hole on the diverter plate 72, and the guide box 7 is connected to the connecting pipe 71. When the electromagnet 722 generates a set of magnetic fields that attract the permanent magnet, the baffle 721 approaches the electromagnet 722, and the baffle 721 blocks the first through hole on the diverter plate 72, while the second through hole on the diverter plate 72 is in an open state. At this time, the guide box 7 is connected to the three-way pipe 15. The present invention can control the flow direction of the liquid in the guide box 7 in real time as needed through the electromagnet 722 and the baffle 721 to ensure the normal operation of pressurization, stirring and the like.

[0033] The working principle of the present invention is as follows: before the spraying operation, the medicine and water are poured into the upper end of the barrel body 1, and the flow guide box 7 is connected to the connecting pipe 71 through the reversing component, and then the first liquid pump 13 is turned on, and the medicine liquid in the barrel body 1 is transported to the flow guide box 7 through the first liquid pump 13, so that the transmission component drives the stirring rod 12 to stir the medicine liquid in the barrel body 1. When the spraying operation is performed, the flow guide box 7 is controlled to be connected to the three-way pipe 15 through the reversing component, and the medicine liquid in the barrel body 1 is transported to the three-way pipe 15 through the second liquid pump 14. At this time, the medicine liquid will flow along the three-way pipe. 15, the delivery pipe 5, the filter chamber, the filter component 46, the handle 3, the spray rod 2 flows, and then is sprayed out from the nozzle. The first liquid pump 13 and the second liquid pump 14 work in coordination to increase the output pressure of the liquid and the system flow at any time as needed. During the spraying process, if the filter component 46 is blocked, the staff can rotate the filter component 46 through the first rotating rod 41 to make the part to be cleaned close to the waste hole. Through the mutual cooperation of the sealing component in the waste liquid tank 42 and the filter component 46, the effect of cleaning while spraying and filtering the component 46 is achieved.

[0034] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. The embodiments should therefore be considered exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
