Description

Technical Field

[0001] This application relates to the field of sprayers, and more particularly to a dual-nozzle adjustable sprayer. Background Technology

[0002] A sprayer is short for spraying equipment. A sprayer is a device that uses air suction to turn liquids such as chemicals into a mist, which is then sprayed evenly onto other objects. It consists of a storage tank, a pump, and a spray gun. The pump drives the solution in the storage tank to be sprayed evenly onto the surfaces of other objects through the spray gun.

[0003] Spray guns are mainly single-nozzle structures, which can only spray in one direction during use. When workers need to spray different corners of an item, they need to readjust the direction of the spray gun and maintain the spray direction, which increases the workload and labor intensity of the workers, thereby reducing the spraying efficiency of the sprayer. Summary of the Invention

[0004] To address the issue of workers needing to adjust the direction of the spray gun and maintain its spray pattern, this application provides a dual-nozzle adjustable sprayer.

[0005] This application provides a dual-nozzle adjustable sprayer, which adopts the following technical solution:

[0006] A dual-nozzle adjustable sprayer includes a sprayer body and a spray gun. The spray gun includes a spray bar, a three-way pipe, a first rotating nozzle, and a second rotating nozzle. The three-way pipe has a first connecting channel and a second connecting channel, the first connecting channel communicating with the second connecting channel. The inner wall of the first connecting channel has a threaded groove for threaded connection of the end of the spray bar. The end of the spray bar away from the three-way pipe is connected to the sprayer body. The first rotating nozzle and the second rotating nozzle are rotatably connected to the two ends of the three-way pipe respectively. Nozzle 2 is located at both ends of connecting channel 2. A sealing assembly is connected to the three-way pipe. A sealing cavity is opened on the outer wall of the three-way pipe. The sealing cavity penetrates the outer wall of the three-way pipe and connects to the threaded groove. The sealing assembly includes a sealing ring and a water-swellable block. The sealing ring is embedded in the inner wall of the threaded groove. The outer wall of the sealing ring abuts against the inner wall of the threaded groove and the end face of the spray bar to form a seal. The water-swellable block is embedded in the sealing cavity. The inner wall of the water-swellable block abuts against the outer wall of the sealing ring and the outer wall of the spray bar. The outer wall of the water-swellable block is flush with the outer wall of the three-way pipe.

[0007] By adopting the above technical solution, the solution inside the sprayer body enters the connecting channel one through the spray bar. The outer wall of the sealing ring abuts against the end face of the spray bar and the inner wall of the threaded groove to form a seal, achieving the sealing stability between the three-way pipe and the end of the spray bar. The inner wall of the water-swellable ring abuts against the outer wall of the spray bar and the outer wall of the sealing ring. When the inner wall of the threaded groove is not threadedly tightened to the outer wall of the spray bar, the solution in the inner cavity of the spray bar overflows through the connection between the outer wall of the spray bar and the inner wall of the threaded groove. The overflowing solution abuts against the inner wall of the water-swellable ring, which absorbs water, expands, and abuts against the outer wall of the sealing ring. The outer wall of the sealing ring deforms under pressure and abuts against the end face of the spray bar to form a seal, further achieving the sealing stability between the three-way pipe and the spray bar. Connecting channel one connects to connecting channel two. The two ends of the connecting channel 2 are rotatably connected to rotating nozzle 1 and rotating nozzle 2 respectively. The solution in the connecting channel 1 enters the rotating nozzle 1 and rotating nozzle 2 through the connecting channel 2 and is sprayed out, thereby increasing the spraying range of the sprayer. When the operator needs to adjust the direction of rotating nozzle 1 and rotating nozzle 2 to spray at different angles, the operator can rotate the orientation of rotating nozzle 1 and rotating nozzle 2 on the three-way pipe. There is no need for the operator to adjust the orientation of the spray bar to change the orientation of rotating nozzle 1 and rotating nozzle 2 and maintain the same posture for spraying, thereby reducing the operator's workload, reducing the labor intensity of the operator, and thus improving the spraying efficiency of the sprayer.

[0008] Optionally, the sealing assembly further includes a transmission component, which includes a first transmission rack, a second transmission rack, and a transmission gear. The transmission gear is rotatably connected to the inner wall of the sealing cavity. The first transmission rack is slidably connected to the inner wall of the sealing cavity, with its end protruding from the inner wall of the threaded groove and abutting against the outer wall of the spray bar. The second transmission rack is slidably connected to the inner wall of the sealing cavity, and the sliding direction of the second transmission rack is parallel to that of the first transmission rack. Both the first and second transmission racks mesh with the transmission gear, and are located on opposite sides of the transmission gear. The end face of the second transmission rack away from the transmission gear is connected to the end face of the water-swellable block. When the outer wall of the spray bar is tightened and fixed to the inner wall of the threaded groove, the outer wall of the spray bar abuts against the end face of the first transmission rack and drives the first transmission rack to slide towards the sealing cavity. The transmission gear rotates, driving the second transmission rack to slide towards the threaded groove, causing the end face of the water-swellable block to be flush with the outer wall of the tee pipe.

[0009] By adopting the above technical solution, when the end of the spray bar is tightened and fixed to the inner wall of the threaded groove, the outer wall of the spray bar abuts against the end face of the transmission rack and drives the transmission rack to slide towards the sealing cavity. The transmission gear rotates, driving the transmission rack to slide towards the threaded groove. The end face of the transmission rack connects with the end face of the water-swellable block, driving the water-swellable block to slide towards the threaded groove. The end face of the water-swellable block is flush with the outer wall of the tee pipe. The operator can directly observe the tightening of the end face of the spray bar and the inner wall of the threaded groove, thereby improving the installation efficiency of the dual-nozzle adjustable sprayer.

[0010] Optionally, the sealing assembly further includes an elastic element, the two ends of which are connected to the inner wall of the sealing cavity and the end of the transmission rack respectively. The elastic element has the elastic force to drive the transmission rack to slide away from the sealing cavity, and the end of the transmission rack tends to protrude from the inner wall of the threaded groove.

[0011] By adopting the above technical solution, when the end of the spray bar disengages from the inner wall of the threaded groove, the clamping force of the outer wall of the spray bar against one end face of the transmission rack disappears. The elastic force of the elastic element drives the transmission rack to slide towards the threaded groove, and one end of the transmission rack protrudes from the inner wall of the threaded groove. The transmission gear rotates, driving the transmission rack to slide away from the threaded groove, which in turn drives the water-swellable block to slide away from the threaded groove. The end of the water-swellable block protrudes from the outer wall of the tee pipe, realizing the automatic reset of the sealing component without the need for adjustment by the operator, thereby reducing the workload of the operator and improving the ease of use of the dual-nozzle adjustable sprayer.

[0012] Optionally, the end face of the transmission rack facing away from the sealing ring is connected to a guide surface. The inclination height of the guide surface increases as the distance to the sealing ring decreases. The guide surface abuts against the outer wall of the spray bar and guides the transmission rack to slide towards the sealing cavity.

[0013] By adopting the above technical solution, when the end of the spray bar is screwed into the inner wall of the threaded groove, the outer wall of the spray bar abuts against the guide surface. The guide surface guides the transmission rack to slide towards the sealing cavity, which in turn drives the water-swellable block to slide towards the threaded groove. The end face of the water-swellable ring is flush with the outer wall of the tee pipe, thereby ensuring the stability of the sealing assembly operation.

[0014] Optionally, the rotating nozzle includes a nozzle seat, which includes a spray section and a rotating section. The end of the rotating section is connected to the outer wall of the spray section. The rotating section has a flow cavity one, and the spray section has a flow cavity two. The flow cavity one communicates with the flow cavity two. The rotating section is rotatably connected to the outer wall of the tee pipe. The flow cavity one communicates with the flow channel two. An elastic ring is connected to the end of the rotating section two away from the spray section. The inner wall of the elastic ring abuts against the outer wall of the tee pipe to form a seal.

[0015] By adopting the above technical solution, the end of the rotating section is rotatably connected to the outer wall of the three-way pipe, and the second connecting channel, the first flow chamber and the second flow chamber are connected in sequence. The solution in the second connecting channel passes through the first flow chamber and the second flow chamber in sequence and is discharged. The inner wall of the elastic ring presses against the outer wall of the three-way pipe to form a seal, so that the solution in the first flow chamber is not easy to overflow from the point where the rotating section and the elastic ring press against each other, reducing the waste of solution and embodying the concept of energy saving.

[0016] Optionally, a clamping assembly is connected to the rotating section. The clamping assembly includes a first clamping arc plate, a second clamping arc plate, and a clamping member. The first and second clamping arc plates are rotatably connected to the end face of the rotating section facing the elastic ring. The first and second clamping arc plates are located on both sides of the axis of the elastic ring. The clamping member is used to fix the first and second clamping arc plates. When the first and second clamping arc plates rotate toward the direction closer to the elastic ring, the clamping member drives the first and second clamping arc plates to close together and form a fixed shape. The inner walls of the first and second clamping arc plates abut against the outer wall of the elastic ring to form a fixed shape. The outer wall of the elastic ring is deformed under pressure and abuts against the outer wall of the tee pipe to form a seal.

[0017] By adopting the above technical solution, the workers drive the first and second clamping arc plates to rotate towards the axis of the elastic ring. The clamping components drive the first and second clamping arc plates to close together and form a fixed structure. The inner walls of the first and second clamping arc plates press against the outer wall of the elastic ring to form a fixed structure. The inner wall of the elastic ring is pressed against the outer wall of the tee pipe to form a seal, further enhancing the sealing stability between the inner wall of the elastic ring and the outer wall of the tee pipe.

[0018] Optionally, the abutting member includes a abutting plate and a abutting strip. One end of the abutting plate is connected to the end of the abutting arc plate away from the rotation axis of the abutting arc plate. The other end of the abutting plate protrudes from the end face of the abutting arc plate. The end face of the abutting plate facing the elastic ring has an abutting groove for accommodating the abutting strip. The abutting strip is connected to the end face of the abutting arc plate near the abutting plate. When the abutting arc plate covers the abutting arc plate, the abutting strip is embedded in the abutting groove, and the outer wall of the abutting strip abuts against the inner wall of the abutting groove to form a fixation.

[0019] By adopting the above technical solution, when the first and second abutting arc plates are closed, the abutting strip is embedded in the abutting groove, and the outer wall of the abutting strip abuts against the inner wall of the abutting groove to form a fixation, thereby fixing the first and second abutting arc plates and making it difficult for the first and second abutting arc plates to rotate, thus improving the abutting stability of the first and second abutting arc plates against the outer wall of the elastic ring.

[0020] Optionally, the tee is coaxially fitted with a deformation ring, and the outer wall of the deformation ring abuts against the inner wall of the elastic ring and the outer wall of the tee to form a seal.

[0021] By adopting the above technical solution, the outer wall of the deformation ring is pressed against the inner wall of the elastic ring and the outer wall of the three-way pipe to form a seal, so that the water in the flow chamber is not easy to overflow from the contact between the inner wall of the elastic ring and the outer wall of the three-way pipe, thereby reducing the waste of solution and embodying the concept of energy saving.

[0022] Optionally, a pressure-changing assembly is connected to the nozzle seat. A pressure-changing chamber is formed in the inner wall of the flow cavity. A sliding hole is formed on the end face of the elastic ring facing the deformation ring. The pressure-changing chamber communicates with the sliding hole. The pressure-changing assembly includes a power rod, a pressure-changing component, a pressure-changing piston, and a sealing rod. The power rod is slidably connected to the inner wall of the pressure-changing chamber, and its end protrudes from the inner wall of the flow cavity. The pressure-changing piston is slidably connected to the inner wall of the pressure-changing chamber, and its circumferential outer wall abuts against the inner wall of the pressure-changing chamber to form a seal. The sealing rod is slidably connected to the inner wall of the sliding hole. The sealing rod is positioned above the outer wall of the deformation ring, with its end facing upwards. The pressure transformer is connected between the pressure transformer piston and the power rod. The pressure transformer receives power from the power rod and drives the pressure transformer piston to slide. When the hydraulic pressure in the flow chamber drives the power rod to slide towards the pressure transformer chamber, the pressure transformer receives power from the power rod and drives the pressure transformer piston to slide, causing air in the pressure transformer chamber to enter the sliding hole. The air pressure in the sliding hole drives the sealing rod to slide towards the deformation ring, and the outer wall of the sealing rod abuts against the outer wall of the deformation ring to form a seal.

[0023] By adopting the above technical solution, when the solution in the connecting channel 2 passes through flow chamber 1 and flow chamber 2 in sequence and is discharged, the hydraulic pressure in flow chamber 1 drives the power rod to slide towards the pressure transformer chamber. The pressure transformer receives the power from the power rod and drives the pressure transformer piston to slide on the inner wall of the pressure transformer chamber. The outer circumferential wall of the pressure transformer piston presses against the inner wall of the pressure transformer chamber, driving the air in the pressure transformer chamber into the sliding hole. The increased air pressure in the sliding hole drives the sealing rod to slide towards the deformation ring. The end face of the sealing rod presses against the outer wall of the deformation ring to form a seal, further improving the sealing stability between the rotating section and the outer wall of the three-way pipe. At the same time, the increased air pressure in the sliding hole drives the elastic ring to expand and deform, further increasing the clamping force between the elastic ring and the clamping arc plate 1 and the clamping arc plate 2.

[0024] Optionally, the transformer assembly further includes an elastic element two, with its two ends in the elastic direction correspondingly connected to the outer wall of the sealing rod and the inner wall of the transformer cavity. The elastic element two has the elastic force to drive the sealing rod to slide away from the deformation ring, and the end of the sealing rod tends to be flush with the inner wall of the flow cavity.

[0025] By adopting the above technical solution, when the dual-nozzle adjustable sprayer is not used, the hydraulic pressure in the first flow chamber disappears, and the elastic force of the second elastic element drives the sealing rod to slide away from the deformation ring. The end of the sealing rod is flush with the inner wall of the first flow chamber, thus realizing the automatic reset of the sealing rod.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The setting of sealing ring and water-expanding ring eliminates the need for operators to adjust the orientation of the spray bar and change the orientation of rotating nozzle one and rotating nozzle two to maintain the same posture for spraying, reducing the workload and labor intensity of operators and improving the spraying efficiency of the sprayer;

[0028] 2. The design of the elastic element enables the automatic reset of the sealing assembly, reducing the workload of operators and improving the ease of use of the sprayer;

[0029] 3. The design of the elastic ring prevents the solution from overflowing from the point where the rotating section and the elastic ring meet, reducing solution waste and embodying the concept of energy saving. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a dual-nozzle adjustable sprayer. (Refer to...) Figure 1 The dual-nozzle adjustable sprayer includes a sprayer body 1 and a spray gun 2. The sprayer body 1 includes a base 11, a liquid storage tank 12, and a pump 13. The liquid storage tank 12 and the pump 13 are fixed to the end face of the base 11 by screws. The water inlet of the pump 13 is connected to the water outlet of the liquid storage tank 12 through a pipe. The water outlet of the pump 13 is connected to the spray gun 2 through a pipe. The pump 13 drives the solution in the liquid storage tank 12 to be sprayed out from the spray end of the spray gun 2 through the pipe, thereby achieving spraying on the end face of the object.

[0037] Reference Figure 1 and Figure 2 The spray gun 2 includes a spray bar 21, a three-way pipe 22, a rotating nozzle 1 23, and a rotating nozzle 24. The three-way pipe 22 includes a threaded part 221 and a connecting part 222. Both the threaded part 221 and the connecting part 222 are cylindrical tubes. The end of the threaded part 221 is welded and fixed to the middle part of the connecting part 222 along its axial direction. The threaded part 221 has a connecting channel 1 2211 coaxially formed. The connecting channel 1 2211 passes through the outer wall of the threaded part 221 along its own axis. The connecting part 222 has a connecting channel 2221 coaxially formed. The connecting channel 2221 passes through the outer wall of the connecting part 222 along its own axis. The connecting channel 1 2211 connects to the connecting channel 2221, and the axis of the connecting channel 1 2211 is perpendicular to the axis of the connecting channel 2221.

[0038] Reference Figure 1 and Figure 2 A threaded groove 2212 is coaxially formed on the inner wall of the connecting channel 2211 away from the connecting channel 2221, for the end of the spray rod 21 to be threaded. One end of the spray rod 21 is tightened and fixed to the inner wall of the threaded groove 2212, and the other end of the spray rod 21 is connected to the pump 13 through a pipe. Rotating nozzle 1 23 and rotating nozzle 2 24 are rotatably connected to both sides of the axis of the connecting part 222, and the rotation axis of rotating nozzle 1 23 coincides with the rotation axis of rotating nozzle 24, and the rotation axis of rotating nozzle 1 23 coincides with the axis of the connecting part 222.

[0039] Reference Figure 2A sealing assembly 3 is connected to the threaded portion 221. A sealing cavity 2213 is formed on the outer wall of the threaded portion 221. The sealing cavity 2213 penetrates the outer wall of the threaded portion 221 in a direction close to the axis of the threaded portion 221 and communicates with the threaded groove 2212. The sealing assembly 3 includes a sealing ring 31, a water-swellable block 32, and a transmission component 33. In this embodiment, the sealing ring 31 can be made of rubber or silicone. In this embodiment, the sealing ring 31 is made of rubber and has a certain deformation capability. The sealing ring 31 is coaxially embedded in the threaded groove 2212. One end of the sealing ring 31 is used to press against the inner wall of the threaded groove 2212 to form a seal, and the other end of the sealing ring 31 presses against the end face of the spray bar 21 to form a seal, thereby achieving a preliminary seal between the spray bar 21 and the three-way pipe 22.

[0040] Reference Figure 2 In this embodiment, the material of the water-swellable block 32 is water-absorbing resin, which has a certain expansion coefficient. The water-swellable block 32 is embedded in the sealing cavity 2213. One end of the water-swellable block 32 abuts against the connection between the sealing ring 31 and the spray bar 21, and the other end of the water-swellable block 32 is flush with the outer wall of the threaded part 221. The transmission component 33 includes a transmission gear 331, a first transmission rack 332, an elastic element 333, and a second transmission rack 334. The first transmission rack 332 is slidably connected to the inner wall of the sealing cavity 2213. The sliding direction of the first transmission rack 332 is parallel to the axis of the connecting part 222. The end of the first transmission rack 332 passes through the sealing cavity 2213 and protrudes from the inner wall of the threaded groove 2212. The second transmission rack 334 is slidably connected to the inner wall of the sealing cavity 2213. The sliding direction of the second transmission rack 334 is parallel to the sliding direction of the first transmission rack 332. The second transmission rack 334 is located between the water-swellable block 32 and the first transmission rack 332, and the end face of the second transmission rack 334 is fixed to the end face of the water-swellable block 32.

[0041] Reference Figure 2 The transmission gear 331 is rotatably connected to the inner wall of the sealing cavity 2213. Transmission racks 332 and 334 mesh with the transmission gear 331, and are located on opposite sides of the axis of the transmission gear 331. The elastic element 333 can be a compression spring or a tension spring; in this embodiment, it is a compression spring with a certain deformation capacity. The two ends of the elastic element 333 in the direction of its elastic force are welded and fixed to the ends of the transmission rack 332 and the inner wall of the sealing cavity 2213, respectively. The direction of the elastic force of the elastic element 333 coincides with the sliding direction of the transmission rack 332. The elastic element 333 has a tendency to forcefully drive the transmission rack 332 towards the threaded groove 2212.

[0042] Reference Figure 2The end face of the transmission rack 332 protruding from the inner wall of the threaded groove 2212 away from the sealing ring 31 is provided with a guide surface 3321. The inclination height of the guide surface 3321 increases as the distance to the sealing ring 31 decreases. The guide surface 3321 is used to abut against the end face of the spray bar 21 and guide the transmission rack 332 to slide towards the sealing cavity 2213. When the end of the spray bar 21 is threaded and fixed to the inner wall of the threaded groove 2212, the guide surface 3321 abuts against the end face of the spray bar 21 and guides the first transmission rack 332 to slide towards the sealing cavity 2213. The transmission gear 331 rotates, driving the second transmission rack 334 to slide towards the threaded groove 2212, which in turn drives the water-expanding block 32 to slide towards the sealing ring 31. One end of the water-expanding block 32 abuts against the connection between the sealing ring 31 and the spray bar 21, and the other end of the water-expanding block 32 is flush with the outer wall of the threaded part 221. The operator can directly observe the tightness between the spray bar 21 and the sealing ring 31, thereby speeding up the installation efficiency of the dual-nozzle adjustable sprayer.

[0043] Reference Figure 2 When the clamping force between the spray bar 21 and the sealing ring 31 decreases, the solution inside the spray bar 21 overflows from the clamping point between the spray bar 21 and the sealing ring 31. The water-absorbing expansion block 32 absorbs water and expands. The deformation of the water-absorbing expansion block 32 compresses the outer wall of the sealing ring 31, causing the sealing ring 31 to deform and press against the end face of the spray bar 21 to achieve a seal. At the same time, the staff can directly understand the clamping condition between the spray bar 21 and the sealing ring 31 by observing the deformation of the water-absorbing expansion block 32, thereby reducing the overflow of solution and reflecting the concept of energy saving.

[0044] Reference Figure 1 and Figure 2 Rotary nozzle 1 23 and rotary nozzle 24 have the same structure. Rotary nozzle 1 23 includes nozzle seat 231, which includes spray section 2311 and rotating section 2312. Both spray section 2311 and rotating section 2312 are cylindrical tubes. The end of rotating section 2312 is welded and fixed to the outer wall of spray section 2311. The axis of rotating section 2312 is perpendicular to the axis of spray section 2311. A flow cavity 1 2313 is coaxially formed in rotating section 2312, and flow cavity 1 2313 penetrates the outer wall of rotating section 2312 along its own axis. A flow cavity 2314 is coaxially formed in spray section 2311, and flow cavity 2314 penetrates the outer wall of spray section 2311 along its own axis. Flow cavity 1 2313 connects to flow cavity 2314.

[0045] Reference Figure 2The end of the connecting part 222 is rotatably connected to the inner wall of the first flow cavity 2313 along its own axis. The axis of the second connecting channel 2221 coincides with the axis of the first flow cavity 2313, and the second connecting channel 2221 communicates with the first flow cavity 2313. An elastic ring 4 is coaxially fixed to the end face of the rotating section 2312 away from the injection section 2311. The material of the elastic ring 4 can be rubber or silicone. In this embodiment, the material of the elastic ring 4 is rubber, which has a certain deformation capability. The inner ring wall of the elastic ring 4 abuts against the outer circumferential wall of the connecting part 222 to form a seal.

[0046] Reference Figure 2 Both ends of the connecting part 222 are coaxially fitted with deformation rings 5. The deformation rings 5 ​​can be made of rubber or silicone.
