Description

Technical Field

[0001] This invention belongs to the field of fluid dynamics technology, and particularly relates to a high-pressure water gun nozzle and a high-pressure water gun. Background Technology

[0002] Polymer products, such as polytetrafluoroethylene (PTFE) products, may have residues of grease, lubricants, mold release agents, and other substances on their surfaces during the manufacturing process. These residues can affect the quality, performance, or appearance of the products, thus requiring cleaning to remove them. High-pressure water guns are commonly used on assembly lines to clean polymer products. They work by increasing the water pressure to a high level and then spraying a high-pressure water jet onto the surface of the polymer product through a nozzle. The powerful impact and shearing force of the high-pressure water jet effectively removes dirt, grease, paint, and other adhering substances.

[0003] However, during the production process, the water pressure supplied by the high-pressure water gun may fluctuate to some extent, which is generally detrimental to the cleaning process of polymer products. For example, when the water pressure suddenly increases, the strong water flow will impact the surface of the polymer product. If the water pressure suddenly rises to a level that the polymer product can withstand, it may cause excessive impact, leading to surface damage. Furthermore, although an increase in water pressure from the high-pressure water gun may bring stronger impact and shearing forces, if the water pressure exceeds the range that the polymer product can withstand, it will actually undermine the cleaning effect, because excessively high water pressure may lead to uneven cleaning and failure to thoroughly remove dirt and impurities.

[0004] In summary, there is a need for a device that can stabilize water pressure and be applied to high-pressure water guns. Summary of the Invention

[0005] The purpose of this invention is to provide a high-pressure water gun nozzle and a high-pressure water gun. The nozzle is equipped with a diversion plate, which can divert the water flow to the secondary end pipe when the water pressure suddenly increases, thereby increasing the water flow rate while maintaining the water pressure at a relatively constant level. This can effectively prevent damage to the product to be cleaned when the water pressure suddenly increases, and can also increase the water flow rate by utilizing the sudden increase in water pressure, thus cleaning the product more quickly.

[0006] The technical solution adopted by the present invention to solve the above problems is: a high-pressure water gun nozzle, comprising:

[0007] The end unit includes a tapered end, a main end tube disposed at the end of the tapered end, and auxiliary end tubes disposed on both sides of the main end tube;

[0008] A diversion plate unit is used to direct water flow to the main end pipe and / or the secondary end pipe;

[0009] A torsion spring is used to mount the drainage plate unit; the torsion spring causes the drainage plate unit to tend to close the secondary end tube.

[0010] A further preferred technical solution is that: the diversion plate unit includes a diversion plate; the diversion plate includes a main flow surface that guides the water flow to the main end pipe, and a secondary flow surface that guides the water flow to the secondary end pipe.

[0011] A further preferred technical solution is that the end unit further includes a positioning groove disposed on the inner side of the tapered end for engaging the secondary guide surface, and a drainage hole for connecting the positioning groove and the secondary end tube.

[0012] A further preferred technical solution is that: the drainage plate further includes a stop surface; the end unit further includes a baffle disposed on the inner side of the conical end; the baffle includes an inner inclined surface for lifting the stop surface.

[0013] A further preferred technical solution is that: the end unit further includes a limiting groove disposed on the inner side of the positioning groove; the diversion plate unit further includes a limiting block disposed on the diversion plate and used to engage the limiting groove.

[0014] A further preferred technical solution is that the limiting block portion includes a limiting block groove disposed on the diversion plate, a limiting block installed in the limiting block groove, and a limiting spring for pushing the limiting block outward.

[0015] A further preferred technical solution is that the limiting block portion further includes an arc-shaped end portion disposed at the outer end of the limiting block.

[0016] A further preferred technical solution is that the limiting block portion further includes an outer blocking block disposed on the inner side of the limiting block groove, and an inner blocking block disposed on the limiting block and used to push up the outer blocking block.

[0017] A further preferred technical solution is that the number of the drainage plate units is not less than the number of the secondary end tubes.

[0018] A high-pressure water gun includes a gun body, a translation device for mounting the gun body, a water pipe connected to the gun body, and a perforated conveyor belt located below the gun body; the high-pressure water gun nozzle is provided at the lower end of the gun body.

[0019] In summary, the present invention has the following advantages:

[0020] 1. Even if the water pressure entering the water gun surges, the water pressure exiting the water gun remains essentially unchanged. Furthermore, the surge in water pressure can be used to increase the water flow rate and improve the cleaning effect on polymer products.

[0021] 2. When the water pressure suddenly increases, the high-pressure water gun can use the increased water pressure to split the flow and form multiple water jet lines. This splitting ability makes the cleaning coverage area wider and can clean multiple targets at the same time, improving cleaning efficiency.

[0022] 3. Under the action of the limiting block engaging the limiting groove, the diversion plate used for diversion will not divert water to the secondary end pipe when the water pressure is normal, thus ensuring its effective cleaning level;

[0023] 4. A baffle is installed inside the conical end to protect the diversion plate and torsion spring from damage caused by sudden increases in water pressure. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0034] Example 1

[0035] In this embodiment, the high-pressure water gun nozzle includes:

[0036] End unit 1, drain plate unit 2, torsion spring 3, wherein:

[0037] The end unit 1 includes a tapered end 101, a main end tube 102, a secondary end tube 103, a positioning groove 104, a drainage hole 105, a baffle 106, and a limiting groove 107.

[0038] The flow guide plate unit 2 includes a flow guide plate 201, a limiting block portion 202, a main flow surface 201a, a stop surface 201c, a secondary flow guide surface 201b, a limiting block groove 202a, a limiting block 202b, a limiting spring 202c, an arc-shaped end 202d, an outer blocking block 202e, and an inner blocking block 202f.

[0039] refer to Figure 1 This diagram illustrates the structure of a high-pressure water gun nozzle. As can be seen, the high-pressure water gun nozzle includes:

[0040] The system comprises an end unit 1, a diversion plate unit 2, and a torsion spring 3 for mounting the diversion plate units 2. The diversion plate units 2 are symmetrically arranged inside the end unit 1, one on the left and one on the right. Each diversion plate unit 2 is equipped with a torsion spring 3, which provides a flipping tendency for the diversion plate unit 2 away from the outlet direction of the end unit 1, ultimately causing the diversion plate unit 2 to be locked onto the inner surface of the end unit 1 and kept horizontal. A small gap is formed between the two diversion plate units 2, allowing water to flow through.

[0041] refer to Figure 2 It showed Figure 1 A schematic diagram showing the flow direction of water within the conical end 101. The diagram shows the main end pipe 102 located at the end of the conical end 101, and the secondary end pipes 103 located on both sides of the main end pipe 102. The guide plate unit 2 directs the water flow to the main end pipe 102 and / or the secondary end pipes 103. The torsion spring 3 causes the guide plate unit 2 to tend to close the secondary end pipes 103. The diagram illustrates that under normal water pressure, the normally flowing water will not damage the surface of the polymer product. Therefore, the current water flow is insufficient to counteract the torsion spring 3, causing the guide plate unit 2 to flip. This blocks the water outlet lines of the secondary end pipes 103 on both sides of the conical end 101, and the water can only flow out from between the two guide plate units 2, forming a small stream of high-pressure water to clean the polymer product.

[0042] refer to Figure 3 It showed Figure 2 The diagram illustrates how an increase in water pressure causes the diversion plate unit to divert some water to the secondary end pipe. The diagram shows a surge in water pressure, at which point the high-pressure water is sufficient to counteract the torsion spring 3, causing the diversion plate unit 2 to flip. At this point, the end of the diversion plate unit 2 used to block the secondary end pipe 103 lifts, allowing water to be diverted through the secondary end pipe 103. This reduces the water pressure flowing out of the main end pipe 102. The effect is that even with a surge in the water pressure entering the water gun, the final water pressure exiting the water gun remains essentially constant. Furthermore, the surge in water pressure can be used to increase the water flow rate, thereby improving the cleaning effect on polymer products.

[0043] refer to Figure 4 The diagram shows the structure of the diversion plate unit and the end unit. The diversion plate unit 2 includes a diversion plate 201; the diversion plate 201 includes a main flow surface 201a that directs water flow to the main end pipe 101, and a secondary flow surface 201b that directs water flow to the secondary end pipe 103. The end unit 1 also includes a positioning groove 104 disposed inside the conical end 101 for engaging the secondary flow surface 201b, and a diversion hole 105 connecting the positioning groove 104 and the secondary end pipe 103. When the diversion plate 201 is lifted by a high-pressure water flow, the secondary flow surface 201b located at the side end of the diversion plate 201 can just guide a portion of the water flow to the positioning groove 104, allowing the water to flow out of the secondary end pipe 103 through the diversion hole 105. Furthermore, when the guide plate 201 is raised, the main flow surface 201a located at the inner end of the guide plate 201 also tilts towards the direction of the main end pipe 102, where it can be reconnected. Figure 2 The relative positions of the main flow surface 201a and the main end pipe 102 are determined to ensure that most of the water flow is guided by the main flow surface 201a and flows out of the main end pipe 102. This design, which utilizes water pressure to achieve bidirectional flow diversion, is extremely ingenious. Furthermore, as the water pressure increases, the angle at which the guide plate 201 is raised also increases, and the gap between the two guide plates 201 becomes larger, allowing more water to flow out from the gap. Given a fixed input water pressure, the greater the flow rate from the main end pipe 102, the lower the final output water pressure. Therefore, the angle at which the guide plate 201 is raised can also regulate the output water pressure to a certain extent. Moreover, as the water pressure increases, the gap between the secondary guide surface 201b and the positioning groove 104 also becomes larger, allowing more water to flow out from the positioning groove 104. This results in not only a greater flow rate from the main end pipe 102, but also a greater flow rate from the secondary end pipes 103 on both sides.

[0044] Furthermore, the diversion plate 201 also includes a stop surface 201c; the end unit 1 also includes a baffle 106 disposed on the inner side of the conical end 101; the baffle 106 includes an inner inclined surface 106a for lifting the stop surface 201c. The function of the baffle 106 is that, when the water pressure is too high, in order to protect the torsion spring 3 from damage due to its elastic deformation range, when the diversion plate 201 is raised to a certain angle, the inner inclined surface 106a of the baffle 106 can just abut against the stop surface 201c on the outer side of the diversion plate 201, thereby preventing the diversion plate 201 from being raised again. Its advantage is that, even when the water pressure is too high, the internal structure of the nozzle will not be directly damaged.

[0045] Furthermore, the end unit 1 also includes a limiting groove 107 disposed on the inner side of the positioning groove 104; the diversion plate unit 2 also includes a limiting block portion 202 disposed on the diversion plate 201 and used to engage the limiting groove 107. Under normal water pressure, there is a possibility that the diversion plate 201 may be slightly raised due to impact, which would result in insufficient sealing of the positioning groove 104 by the diversion plate 201, causing some water to flow out from the secondary end pipe 103. Under normal water pressure, water flowing out from the secondary end pipe 103 is undesirable because it would lead to a pressure loss in the water flowing out of the main end pipe 102, thus failing to provide a cleaning effect. Therefore, the function of the limiting block 202 is that when the limiting block 202 is stuck in the limiting groove 107, no water will flow out from the secondary end pipe 103, no matter how high the water pressure is. Only when the water pressure is high enough that the secondary end pipe 103 needs to divert the flow will the limiting block 202 be dislodged from the limiting groove 107 under the tendency of the diversion plate 201 to be lifted, thereby canceling the blocking effect on the positioning groove 104 and allowing some water to flow out from the secondary end pipe 103.

[0046] refer to Figure 5The diagram shows the structure of the limiting block portion 202. It can be seen that the limiting block portion 202 includes a limiting block groove 202a disposed on the diversion plate 201, a limiting block 202b installed in the limiting block groove 202a, and a limiting spring 202c for pushing the limiting block 202b outward. When the limiting block portion 202 engages with the limiting groove 107, specifically, the limiting block 202b is engaged in the limiting groove 107, and the limiting block 202b can slide along the limiting block groove 202a. Under the outward pushing action of the limiting spring 202c, the limiting block 202b is always fully engaged in the limiting groove 107. Furthermore, the limiting block portion 202 also includes an arc-shaped end 202d disposed at the outer end of the limiting block 202b. When the drainage plate 201 is lifted, the limiting block 202b is bent in the vertical direction along the axis of the limiting block 202b until the bending force is large enough so that the arc end 202d can slide out of the limiting groove 107. At this time, the limiting block 202b is freed from the limitation of the limiting groove 107.

[0047] Furthermore, the limiting block portion 202 also includes an outer blocking block 202e disposed on the inner side of the limiting block groove 202a, and an inner blocking block 202f disposed on the limiting block 202b and used to push up the outer blocking block 202e. Under the pushing action of the outer blocking block 202e on the inner blocking block 202f, on the one hand, the arc-shaped end 202d will not completely enter the limiting groove 107, but will be in a suitable position, so that the arc of the arc-shaped end 202d is just against the opening of the limiting groove 107, achieving both engagement and disengagement from the limiting groove 107 under a certain force. On the other hand, the outer blocking block 202e ensures that the limiting block 202b will not dislodge from the limiting block groove 202a under any circumstances.

[0048] Example 2

[0049] In this embodiment, the high-pressure water gun includes a gun body 11, a translation device 12, a water pipe 13, and a perforated conveyor belt 14; wherein the gun body 11 is equipped with the high-pressure water gun nozzle of Embodiment 1.

[0050] refer to Figure 6This diagram illustrates the structure of a high-pressure water gun with an end cap. The high-pressure water gun includes a gun body 11, a translation device 12 mounting the gun body 11, a water pipe 13 connecting the gun body 11, and a perforated conveyor belt 14 located below the gun body 11. The gun body 11 is the main part of the water gun, and it sprays and rinses the object being cleaned via the water pipe 13. The translation device 12, mounted on the gun body, allows the gun body 11 to move horizontally, facilitating adjustments during cleaning operations to cover a wider cleaning area or perform reciprocating cleaning. The perforated conveyor belt 14, located below the gun body, is a moving conveyor belt used to carry, transfer, and position objects being cleaned, such as polymer products. The perforations in the perforated conveyor belt 14 allow high-pressure water to pass through, achieving rinsing and cleaning of the object.

[0051] refer to Figure 7 It showed Figure 6 A schematic diagram from a side view. It can be seen that the translation device 12 is specifically a slide rail perpendicular to the travel direction of the perforated conveyor belt 14. A power device mounted on the slide rail drives the gun body 11 to translate along the slide rail, achieving the movement effect. The slide rail is mounted on a base and typically has a low coefficient of friction to ensure smooth movement of the gun body 11. Alternatively, the gun body 11 can be mounted in the slide rail via a slider and moved by a transmission device that provides power and controls the translation device. The transmission device can be electric or pneumatic. The transmission device can achieve the movement of the translation device through a motor, cylinder, or other mechanical device. Furthermore, the high-pressure water gun also includes a control system for controlling the start, stop, speed, and position of the translation device. The control system can include buttons, switches, controllers, and sensors for operating and monitoring the movement of the translation device.
