Toy water gun

Abstract

The utility model relates to a toy water gun which is characterized in that when a liquid pump is started, liquid in a liquid storage device is injected into a first water tank through a water inlet hole. At the moment, the liquid pump serves as a unique power source and synchronously executes two functions: firstly, liquid in the first water tank is pumped through the water outlet hole to be pressurized, and high-pressure jet water flow is formed; secondly, a dynamic pressure field is built in the first water tank, and part of liquid is forced to flow to the second water tank through the water supplementing hole. The single-pump double-output design directly replaces a transmitting water pump and a spraying water pump which work independently in a traditional double-pump system, and power consumption is reduced fundamentally. In addition, the liquid flowing into the second water tank continuously infiltrates the atomization piece through the through hole under the action of gravity, and liquid atomization spraying is achieved. Therefore, when atomization needs to be suspended, namely the atomization piece stops atomizing the liquid, even if the liquid is still conveyed to the second water tank, the excessive liquid in the second water tank can still automatically return to the first water tank through the backflow hole for liquid spraying.

Description

Technical Field

[0001] This utility model relates to the field of toys, and more particularly to toy water guns. Background Technology

[0002] Toy water guns work by pressurizing and pumping liquid, giving a certain amount of liquid kinetic energy so that it can be shot out at a certain speed. To improve realism, modern water guns often include a flame mechanism that sprays water mist and illuminates it, simulating the effect of a gun flame.

[0003] However, the nozzle mechanism on a toy water gun requires an additional spray pump and atomizing tank. The spray pump draws liquid into the atomizing tank, allowing the atomizing element on the tank to directly contact the liquid, thus atomizing and spraying it out. This design necessitates two pumps—a dispensing pump and a spray pump—significantly increasing power consumption and resulting in poor battery life. Utility Model Content

[0004] This invention provides a toy water gun that retains the spray function while ensuring continuous operation.

[0005] This utility model provides a toy water gun, which includes:

[0006] Gun body;

[0007] A liquid storage device is disposed on the gun body; and

[0008] A pumping atomizing device includes a liquid pump, a first water tank, a second water tank, and an atomizing element. The liquid pump is mounted on the gun body. The first water tank has an inlet, an outlet, a replenishment hole, and a return hole. The inlet is connected to the liquid storage device, the outlet is connected to the liquid pump, the replenishment hole is connected to the second water tank, the second water tank has a through hole that leads to the atomizing element, and the second water tank is connected to the return hole.

[0009] When the liquid pump is working, the liquid in the liquid storage device enters the first water tank through the water inlet. The liquid in the first water tank is not only input into the liquid pump through the water outlet and thus pressurized and sprayed out, but also input into the second water tank through the water replenishment hole and further transported to the atomizing element through the through hole. Excess liquid in the second water tank that is not atomized flows back into the first water tank through the return hole.

[0010] Preferably, the pumping atomizing device further includes a housing and an isolating component, the isolating component being disposed inside the housing, one side of the isolating component enclosing the first water tank with the inner wall of the housing, and the other side of the isolating component enclosing the second water tank with the inner wall of the housing;

[0011] The housing is provided with the water inlet, the water outlet and the through hole, and the water replenishment hole and the return hole are opened on the isolation component.

[0012] Preferably, the atomizing component includes a fixing plate and an atomizing sheet, the fixing plate being disposed on the housing, the atomizing sheet being disposed on the fixing plate, and the atomizing sheet covering the through hole.

[0013] Preferably, the isolation component includes an isolation plate and a guide tube, both of which are located inside the box. The guide tube is disposed on the isolation plate, and the two sides of the isolation plate respectively enclose the first water tank and the second water tank with the inner wall of the box. The water inlet hole is provided on the isolation plate.

[0014] One end of the guide tube abuts against the inner wall of the tank, so that the guide tube and the inner wall of the tank together enclose the guide channel. The water outlet is connected to the guide channel. One end of the guide tube is provided with an overflow hole, which is connected to the first water tank and the guide channel. The other end of the guide tube is provided with the return hole.

[0015] The guide channel not only receives excess un-atomized liquid from the second water tank through the return hole, but also receives liquid from the first water tank through the overflow hole.

[0016] Preferably, the toy water gun further includes a light-emitting device, which includes a mounting tube, a bracket, a light panel, and LED beads;

[0017] The mounting cylinder is disposed on the gun body, the bracket is disposed inside the mounting cylinder, the lamp plate is disposed inside the bracket, and the lamp beads are disposed on the lamp plate;

[0018] The bracket has spray holes, and the bracket and the inner wall of the mounting cylinder together define a plurality of spray holes. The spray holes are connected to the liquid pump and are used to receive the liquid pumped out by the liquid pump and guide it to be sprayed out. Each spray hole is connected to the atomizing element.

[0019] Preferably, the position of the reflux hole is higher than the position of the water inlet hole.

[0020] Preferably, the diameter of the water inlet hole and the diameter of the water outlet hole are both larger than the diameter of the water replenishment hole;

[0021] The diameter of the inlet hole and the diameter of the outlet hole are both larger than the diameter of the return hole.

[0022] Preferably, the diameter of the water inlet hole is 1.5mm to 4.5mm; and / or

[0023] The diameter of the water outlet is 1.5mm to 4.5mm; and / or

[0024] The diameter of the water inlet hole is 0.8mm to 2.5mm; and / or

[0025] The diameter of the reflux hole is 0.8mm to 2.5mm.

[0026] Preferably, the liquid pump includes a motor, a gear transmission assembly, a pump barrel, a piston, a spring, and a nozzle;

[0027] The motor is located inside the gun body and is intermittently driven to the piston via the gear transmission group. The pump cylinder is located on the gun body and the piston is slidably located inside the pump cylinder. The cartridge is driven to the piston. The pump cylinder has a pump suction hole and a pump discharge hole. The pump suction hole is connected to the water outlet hole. The nozzle is located on the pump discharge hole.

[0028] When the motor drives the piston to move through the gear transmission group, liquid is drawn in through the pump suction hole, and the piston supports or drives the deformation of the spring retainer to increase the elastic potential energy of the spring retainer; the spring retainer is used to drive the piston to reset and move when released, so that the liquid in the pump barrel flows through the pump outlet hole to the nozzle for spraying.

[0029] Preferably, the gear transmission assembly includes a drive gear, several transmission gears, intermittent gears, and a rack;

[0030] The motor is connected to the drive gear, and the transmission gears mesh sequentially. The drive gear meshes with one of the transmission gears, and the intermittent gear is coaxially connected with another transmission gear. The rack is connected to the piston, and the intermittent gear meshes with the rack intermittently.

[0031] When the intermittent gear meshes with the rack, the drive gear is driven by the motor to rotate each of the transmission gears, thereby driving the intermittent gear to rotate and driving the piston to move through the rack;

[0032] When the intermittent gear separates from the rack, the elastic element is released to drive the piston to return to its original position.

[0033] Preferably, the gun body is provided with a mounting groove, and a liquid guide head is provided in the mounting groove, the liquid guide head being connected to the water inlet hole;

[0034] The liquid storage device includes a drum and a connector. The drum has a liquid cavity inside, and the connector is disposed on the drum and communicates with the liquid cavity. The drum can be detachably inserted into the mounting groove, thereby communicating with the liquid guide head.

[0035] The following are the beneficial effects of implementing this utility model:

[0036] This utility model relates to a toy water gun. When the liquid pump is activated, liquid from the storage device is injected into the first water tank through the inlet. At this time, the liquid pump acts as the sole power source, simultaneously performing two functions: first, it draws liquid from the first water tank through the outlet and pressurizes it to form a high-pressure jet of water; second, it establishes a dynamic pressure field inside the first water tank, forcing some liquid to flow to the second water tank through the replenishment hole. This single-pump dual-output design directly replaces the independently operating launching and spraying water pumps in traditional dual-pump systems, fundamentally reducing power consumption.

[0037] Furthermore, the liquid flowing into the second water tank continuously wets the atomizing element through the through-hole under the influence of gravity, achieving liquid atomization and spraying. Therefore, when the atomization demand is suspended, that is, when the atomizing element stops atomizing the liquid, even though the liquid will still be delivered to the second water tank, the excess liquid in the second water tank can still be automatically returned to the first water tank through the return hole for spraying.

[0051] Figure 1 and Figure 2 The toy water gun 10 shown in some embodiments of the present invention includes a gun body 1, a liquid storage device 2 and a pumping atomizing device 3.

[0052] Understandably, the external structure of the gun body 1 can be flexibly designed, and the gun body 1 serves to install and support the other components. A liquid storage device 2 is mounted on the gun body 1 and is used to collect liquid. A pumping atomizing device 3 is mounted on the gun body 1 and is connected to the liquid storage device 2. The pumping atomizing device 3 is used both to pressurize and spray the liquid, and also to atomize and spray the liquid.

[0053] like Figures 1 to 8 As shown, the pumping atomizing device 3 includes a liquid pump 31, a first water tank 32, a second water tank 33, and an atomizing element 34. The liquid pump 31 is mounted on the gun body 1. The first water tank 32 has an inlet hole 321, an outlet hole 322, a replenishment hole 323, and a return hole 324. The inlet hole 321 is connected to the liquid storage device 2, the outlet hole 322 is connected to the liquid pump 31, the replenishment hole 323 is connected to the second water tank 33, the second water tank 33 has a through hole 331, the through hole 331 is connected to the atomizing element 34, and the second water tank 33 is connected to the return hole 324.

[0054] When the liquid pump 31 is working, the liquid in the liquid storage device 2 enters the first water tank 32 through the water inlet 321. The liquid in the first water tank 32 is not only input into the liquid pump 31 through the water outlet 322 and pressurized and sprayed out, but the liquid in the first water tank 32 is also input into the second water tank 33 through the water replenishment hole 323 and further transported to the atomizing element 34 through the through hole 331. The excess liquid in the second water tank 33 that is not atomized flows back to the first water tank 32 through the return hole 324.

[0055] Understandably, the liquid pump 31 is mounted on the gun body 1 and is used to pressurize and output the liquid with kinetic energy. The first water tank 32 is connected to the liquid storage device 2 through the water inlet 321 and is used to receive the basic liquid flow; the water outlet 322 of the first water tank 32 guides the liquid to the liquid pump 31 for pressurized spraying, the water replenishment hole 323 is connected to the second water tank 33 to deliver the liquid required for atomization, and the return hole 324 forms a closed loop with the second water tank 33 to recover excess liquid.

[0056] The second water tank 33 is connected to the atomizing element 34 through a through hole 331. The opening of the through hole 331 allows the liquid to flow to the atomizing element 34 for atomization. The connection between the through hole 331 and the water supply hole 323 enables liquid diversion, while the connection between the through hole 331 and the return hole 324 ensures the liquid recycling rate. The atomizing element 34 is used to atomize and spray the liquid conveyed by the through hole 331.

[0057] It should be noted that when the liquid pump 31 starts, the liquid in the storage device 2 enters the first water tank 32 through the water inlet 321, and is divided into two paths: one path enters the liquid pump 31 through the water outlet 322, is pressurized, and then sprayed out at high speed; the other path enters the second water tank 33 through the water replenishment hole 323, and is then transported to the atomizing element 34 through the through hole 331 to complete the atomization spray. Excess liquid in the second water tank 33 that is not atomized returns to the first water tank 32 through the return hole 324, forming a dynamic balance.

[0058] It should also be noted that the atomizing element 34 can be configured with various components that are capable of atomizing liquids in the prior art.

[0059] like Figures 3 to 8 As shown, in some embodiments of the toy water gun, the pumping atomizing device 3 further includes a housing 35 and an isolating member 36. The isolating member 36 is disposed inside the housing 35. One side of the isolating member 36 and the inner wall of the housing 35 enclose a first water tank 32, and the other side of the isolating member 36 and the inner wall of the housing 35 enclose a second water tank 33.

[0060] The housing 35 is provided with a water inlet 321, a water outlet 322 and a through hole 331, and a water replenishment hole 323 and a return hole 324 are provided on the isolation component 36.

[0061] Understandably, the housing 35 is used to store the liquid transferred from the liquid storage device 2. The separator 36 is used to divide the internal space of the housing 35 into two chambers, one chamber being the first water tank 32 and the other chamber being the second water tank 33. Through the nested structure of the separator 36 and the housing 35, physical isolation and liquid interaction between the first water tank 32 and the second water tank 33 are achieved, resulting in a compact structure and high sealing performance.

[0062] It should be noted that in this embodiment, the required connection between the first water tank 32 and the second water tank 33 can be achieved simply by opening a water supply hole 323 and a return hole 324 on the isolation component 36. This means that no pipes are required to connect the water supply hole 323 and the return hole 324 to the second water tank 33, thus completing the supply of liquid to the second water tank and the return of excess liquid. This significantly reduces the product's production cost, simplifies assembly, and improves production and assembly efficiency; it also enhances the overall compactness of the product.

[0063] like Figures 4 to 8 As shown, in some embodiments of the toy water gun, the atomizing component 34 includes a fixing plate 341 and an atomizing plate 342. The fixing plate 341 is disposed on the housing 35, and the atomizing plate 342 is disposed on the fixing plate 341. The atomizing plate 342 covers the through hole 331.

[0064] Understandably, the rigid connection between the fixing plate 341 and the housing 35 ensures the alignment accuracy of the atomizing plate 342 and the through hole 331, improving atomization stability. The atomizing plate 342 directly blocks the through hole 331, so that the liquid is immediately processed by the atomizing plate 342 after passing through the through hole 331, reducing atomization delay. At the same time, the fixing plate 341 provides a mounting base for the atomizing plate 342, facilitating disassembly, maintenance, or replacement of the atomizing plate 342.

[0065] It should be noted that the atomizing plate 342 can be configured as a microporous atomizing plate commonly used in the prior art, or it can be configured as other components in the prior art that can form a liquid to receive and generate water mist.

[0066] like Figures 4 to 8 As shown, in some embodiments of the toy water gun, the isolation component 36 includes an isolation plate 361 and a guide tube 362. Both the isolation plate 361 and the guide tube 362 are located inside the housing 35. The guide tube 362 is disposed on the isolation plate 361. The two sides of the isolation plate 361 are respectively enclosed by the inner wall of the housing 35 to form a first water tank 32 and a second water tank 33. A water replenishment hole 323 is provided on the isolation plate 361.

[0067] One end of the guide tube 362 abuts against the inner wall of the tank 35, so that the guide tube 362 and the inner wall of the tank 35 together form a guide channel 363. The water outlet 322 is connected to the guide channel 363. One end of the guide tube 362 is provided with an overflow hole 3621, which is connected to the first water tank 32 and the guide channel 363. The other end of the guide tube 362 is provided with a return hole 324.

[0068] The guide channel 363 not only receives excess un-atomized liquid in the second water tank 33 through the return hole 324, but also receives liquid in the first water tank 32 through the overflow hole 3621.

[0069] Understandably, the guide tube 362 is mounted on the isolation plate 361, and the guide tube 362 and the isolation plate 361 can be configured to be snap-fitted, glued, or screwed together; of course, the guide tube 362 and the isolation plate 361 can also be configured to be integrally molded together. The isolation plate 361 divides the interior of the tank 35 into a first water tank 32 and a second water tank 33, thereby preventing the mixing of liquids in the two tanks (the first water tank and the second water tank) through physical isolation, while achieving controllable liquid interaction through the water inlet hole 323. Secondly, by setting the flow passage hole 3621 and the return hole 324 on the guide tube 362, the path efficiency of liquid from the first water tank 32 to the liquid pump 31 and the return of excess liquid from the second water tank 33 is optimized.

[0070] It should be noted that during actual operation, the guide channel 363 can centrally guide two streams of liquid (pressurized liquid from the first water tank 32 and return liquid from the second water tank 33) to the liquid pump 31. In this way, since the pressurized liquid and the return liquid flow in through the two ends of the guide channel 363 respectively, liquid turbulence interference is avoided, ensuring the stability of pressurized injection and liquid circulation.

[0071] like Figures 1 to 3 As shown, in some embodiments of the toy water gun, the toy water gun also includes a light-emitting device 4, such as... Figure 4 and Figure 5 As shown, the light-emitting device 4 includes a mounting cylinder 41, a bracket 42, a lamp board 43, and lamp beads 44;

[0072] Mounting cylinder 41 is mounted on gun body 1, bracket 42 is mounted inside mounting cylinder 41, lamp plate 43 is mounted inside bracket 42, and lamp bead 44 is mounted on lamp plate 43.

[0073] The bracket 42 is provided with a spray hole 421. The inner wall of the bracket 42 and the mounting cylinder 41 together define a plurality of spray holes 422. The spray hole 421 is connected to the liquid pump 31. The spray hole 421 is used to receive the liquid pumped out by the liquid pump 31 and guide it to be sprayed out. Each spray hole 422 is connected to the atomizing element 34.

[0074] Understandably, the mounting cylinder 41 can be configured to be mounted on the gun body 1 via a snap-fit, bolt, plug-in, snap-fit, or integral molding method. The bracket 42 is used to fix the light plate 43 and separate the flow channels of the spray nozzle 421 and the spray hole 422. The light plate 43 can be configured with a circuit board capable of driving the LED beads 44 to emit light, as is available in the prior art. The light emitted by the LED beads 44 can illuminate the sprayed water mist, enhancing the visual effect through light refraction by the spray, simulating the gun flame effect, improving the realism of the product, and enriching its functionality. The spray nozzle 421 is used to guide the water column pressurized by the liquid pump 31 for spraying. The spray hole 422 is used for the water mist to pass through.

[0075] like Figure 6 and Figure 8 As shown, in some embodiments of the toy water gun, the position of the return hole 324 is higher than the position of the water inlet hole 323.

[0076] Understandably, in this embodiment, liquid supply priority control is achieved through spatial height difference to ensure that the atomizing liquid in the second water tank 33 is sufficient before any excess liquid is discharged through the high-level return hole 324.

[0077] It should be noted that when the liquid level in the second water tank 33 is lower than that in the return hole 324, the water supply hole 323 continuously replenishes liquid to prioritize meeting the liquid requirements of the atomizing element 34. After the liquid level rises to the height of the return hole 324, the excess liquid automatically flows back to the first water tank 32 to prevent the second water tank 33 from overflowing.

[0078] like Figure 6 and Figure 8 As shown, in some embodiments of the toy water gun, the diameter of the inlet hole 321 and the diameter of the outlet hole 322 are both larger than the diameter of the water replenishment hole 323; the diameter of the inlet hole 321 and the diameter of the outlet hole 322 are both larger than the diameter of the return hole 324.

[0079] Understandably, the large-diameter inlet 321 quickly replenishes the liquid in the storage device 2 to the first water tank 32, preventing the liquid pump 31 from running dry due to insufficient liquid supply. The large-diameter outlet 322 matches the high flow rate output requirements of the liquid pump 31, reducing flow resistance and increasing the water jet range. The small-diameter replenishment hole 323 limits the liquid flow rate from the first water tank 32 to the second water tank 33, preventing a sudden rise in the liquid level of the second water tank 33 from overloading the atomizing plate 342. The small-diameter return hole 324 slows down the return flow rate, preventing sudden pressure changes in the first water tank 32 from interfering with the stable operation of the liquid pump 31.

[0080] More specifically, the diameter of the inlet hole 321 is 1.5mm to 4.5mm. The diameter of the outlet hole 322 is 1.5mm to 4.5mm. The diameter of the water supply hole 323 is 0.8mm to 2.5mm. The diameter of the return hole 324 is 0.8mm to 2.5mm.

[0081] like Figures 4 to 8 As shown, in some embodiments of the toy water gun, the liquid pump 31 includes a motor 311, a gear transmission assembly 312, a pump barrel 313, a piston 314, a cartridge 315, and a nozzle 316.

[0082] The motor 311 is installed inside the gun body 1. The motor 311 is intermittently driven to the piston 314 through the gear transmission group 312. The pump cylinder 313 is installed on the gun body 1. The piston 314 is slidably installed inside the pump cylinder 313. The cartridge 315 is driven to the piston 314. The pump cylinder 313 is provided with a pump suction hole 3131 and a pump discharge hole 3132. The pump suction hole 3131 is connected to the water outlet hole 322. The nozzle 316 is installed on the pump discharge hole 3132.

[0083] When the motor 311 drives the piston 314 to move through the gear transmission group 312, the liquid is drawn in through the pump suction hole 3131, and the piston 314 supports or drives the deformation of the spring retainer 315 to increase the elastic potential energy of the spring retainer 315; the spring retainer 315 is used to drive the piston 314 to reset and move when released, so that the liquid in the pump barrel 313 flows to the nozzle 316 through the pump outlet hole 3132 and is ejected.

[0084] Understandably, the motor 311 indirectly drives the piston 314 to reciprocate through the gear transmission assembly 312. The gear transmission assembly 312 is used to transmit and convert the rotational motion of the motor 311 into the linear motion of the piston 314. The pump barrel 313 is used to accommodate the piston 314 and form a sealed cavity. The pump suction port 3131 and the pump discharge port 3132 are used for liquid intake and discharge, respectively. The piston 314 is used to slide within the pump barrel 313. The piston 314 can transmit the elastic potential energy of the spring retainer 315 to compress the liquid, and can also create a negative pressure within the pump barrel 313 to pump the liquid. The spring retainer 315 can deform and store energy when the piston 314 moves, and drive the piston 314 to reset when released. The nozzle 316 is used to constrain the direction of liquid injection; further, the nozzle 316 can be configured as a constricted shape to increase the liquid injection speed and range.

[0085] like Figures 3 to 5 As shown, in some embodiments of the toy water gun, the gear transmission assembly 312 includes a drive gear 3121, a plurality of transmission gears 3122, an intermittent gear 3123, and a rack 3124.

[0086] The motor 311 drives the drive gear 3121, and the transmission gears 3122 mesh in sequence. The drive gear 3121 meshes with one of the transmission gears 3122, and the intermittent gear 3123 is coaxially connected with another transmission gear 3122. The rack 3124 is connected to the piston 314, and the intermittent gear 3123 and the rack 3124 mesh intermittently.

[0087] When the intermittent gear 3123 meshes with the rack 3124, the drive gear 3121, driven by the motor 311, drives each transmission gear 3122 to rotate, thereby driving the intermittent gear 3123 to rotate and, through the rack 3124, driving the piston 314 to move. When the intermittent gear 3123 separates from the rack 3124, the elastic element is released to drive the piston 314 to return to its original position.

[0088] Understandably, the drive gear 3121 connects to the output shaft of the motor 311 to transmit initial rotational power. Multiple transmission gears 3122 are configured, meshing sequentially to transmit torque along a predetermined path. An intermittent gear 3123 periodically meshes with and disengages from the rack 3124 to control the intermittent movement of the piston 314. The rack 3124 converts the rotational motion of the intermittent gear 3123 into linear displacement of the piston 314.

[0089] It should be noted that the series arrangement of the multi-stage transmission gears 3122 reduces the size of the transmission system, making it suitable for the miniaturized design of toy water guns. The elastic element can be configured as a spring or other elastic components in the prior art.

[0090] like Figure 3As shown, in some embodiments of the toy water gun, the gun body 1 is provided with a mounting groove 11, and a liquid guide head 111 is provided in the mounting groove 11, which is connected to the water inlet 321.

[0091] The liquid storage device 2 includes a drum 21 and a connector 22. The drum 21 has a liquid chamber 211 inside, and the connector 22 is disposed on the drum 21 and communicates with the liquid chamber 211. The drum 21 can be detachably inserted into the mounting groove 11, so that the connector 22 communicates with the liquid guide head 111.

[0092] Understandably, the contour of the mounting groove 11 is adapted to the outer casing structure of the drum 21, allowing the drum 21 to be securely mounted within the mounting groove 11. After the drum 21 is aligned and mounted within the mounting groove 11, the connector 22 will be inserted into the liquid guide head 111, thereby allowing the liquid chamber 211 to be connected to the first water tank 32 through the connector 22, the liquid guide head 111, and the water inlet 321.

[0093] The following are the beneficial effects of implementing this utility model:

[0094] This utility model relates to a toy water gun. When the liquid pump is activated, liquid from the storage device is injected into the first water tank through the inlet. At this time, the liquid pump acts as the sole power source, simultaneously performing two functions: first, it draws liquid from the first water tank through the outlet and pressurizes it to form a high-pressure jet of water; second, it establishes a dynamic pressure field inside the first water tank, forcing some liquid to flow to the second water tank through the replenishment hole. This single-pump dual-output design directly replaces the independently operating launching and spraying water pumps in traditional dual-pump systems, fundamentally reducing power consumption.

[0095] Furthermore, the liquid flowing into the second water tank continuously wets the atomizing element through the through-hole under the influence of gravity, achieving liquid atomization and spraying. Therefore, when the atomization demand is suspended, that is, when the atomizing element stops atomizing the liquid, even though the liquid will still be delivered to the second water tank, the excess liquid in the second water tank can still be automatically returned to the first water tank through the return hole for spraying.
