Adjustable angle water lance

Abstract

The present application provides an adjustable angle water gun, which comprises a handle, a nozzle, a switch assembly and a fastener. A first pivot part of the handle is pivotally connected to a second pivot part of the nozzle, so that the nozzle can be pivoted relative to the handle. The fastener is connected to the outside of the first pivot part of the handle and the outside of the second pivot part of the nozzle by a first end and a second end, respectively, so that the first pivot part and the second pivot part are clamped by the fastener. Therefore, the user uses a knob of the switch assembly to drive the control shaft to rotate, so as to control the water flow of the water gun. Since the fastener is arranged, the joint of the handle and the nozzle is tightly matched, so as to prevent the water leakage.

Description

Technical Field

[0001] This invention relates to the field of water spray gun technology, and more particularly to an adjustable-angle water spray gun, which achieves the function of adjustable angle by pivotally connecting the handle and the nozzle. Background Technology

[0002] In gardening, handheld water guns are typically used to connect to water hoses. A water gun usually consists of a handle, nozzle, switch, and adapter. Users can adjust the nozzle to achieve different spraying modes and control the water flow rate using the switch.

[0003] Patent No. I559983 discloses a water gun structure. By rotating the handle, the water control valve and stop are activated, changing the angle of the water control valve. This aligns the water inlet and outlet of the water control valve, allowing water to flow smoothly and achieve the desired function. Alternatively, the water flow rate can be controlled by using the peripheral wall of the control chamber to create varying degrees of obstruction to the water inlet, thus determining whether to use a large or small volume of water for irrigation. However, while this water gun allows adjustment of the water flow rate, the angle between the barrel and the handle cannot be adjusted. In different working environments, the user must manually adjust the grip angle to change the spray area, which can easily increase the strain on the user's wrist.

[0004] Currently, some water guns offer adjustable angle structures, typically with a shaft or universal joint between the nozzle and handle, allowing the nozzle to swing relative to the handle. However, these water guns are usually made of plastic, resulting in an insufficient seal between the nozzle and handle. Furthermore, the seal relies solely on a sealing ring to enhance the seal, limiting its pressure resistance. Consequently, the connection between the nozzle and handle often loosens during use, leading to leaks, and may even crack due to high water pressure.

[0005] Therefore, the inventor considered how to provide a water gun with an adjustable angle while strengthening its structural strength to prevent leakage or damage during use. Summary of the Invention

[0006] In view of the many defects of the existing water guns, the main objective of the present invention is to provide an adjustable angle water gun that uses a pivot structure to connect the handle and the nozzle, and strengthens the structural strength at the connection between the handle and the nozzle, so that the water gun can avoid leakage or damage during use.

[0007] To achieve the aforementioned main objectives, the present invention provides a water gun comprising a handle, a nozzle, a switch assembly, and a fastener. The handle has a handle body, a water inlet channel disposed within the handle body, and a first pivot portion communicating with the water inlet channel. One end of the handle body is connected to a water source entering the water inlet channel, and the other end of the handle body is provided with the first pivot portion. The nozzle has a nozzle body, a water outlet channel disposed within the nozzle body, and a second pivot portion communicating with the water outlet channel. The second pivot portion is pivotally connected to the first pivot portion of the handle, allowing the nozzle to pivot relative to the handle. The switch assembly is disposed between the handle and the nozzle. The switch assembly has an actuating member and a set of control shafts disposed on the actuating member. The actuating member can drive the control shafts to rotate between a first position and a second position. When the control shaft rotates to the first position, the water inlet channel of the handle and the water outlet channel of the nozzle are not connected. When the control shaft rotates to the second position, the water inlet channel of the handle and the water outlet channel of the nozzle are connected. The fastener has a first end and a second end connected to the first end. The first end is assembled to the outside of the first pivot portion of the handle, and the second end is assembled to the outside of the second pivot portion of the nozzle, so that the first pivot portion and the second pivot portion are clamped to the inside of the fastener.

[0008] Through the aforementioned technical features, the handle and nozzle are connected by a first and second pivot joint, forming a bending structure that allows the nozzle to rotate. This enables the angle between the nozzle and the handle to range from 90 degrees to 180 degrees, increasing the ease of use of the water gun. Furthermore, the fasteners strengthen the fit between the handle and the nozzle, securing the first and second pivot joints. Even under high water pressure, the handle and nozzle are firmly held in place, preventing water leakage from the joint and thus improving the water gun's pressure resistance.

[0009] Preferably, the first pivot portion of the handle has a first through hole that penetrates the first pivot portion, and the second pivot portion of the nozzle has a second through hole that penetrates the second pivot portion. The first through hole connects to the second through hole, and the control shaft of the switch assembly passes through both the first and second through holes. Therefore, the control shaft located between the handle and the nozzle can control the opening and closing of the water flow.

[0010] Preferably, the water gun further includes a positioning element, with a first pivot portion of the handle forming multiple positioning holes and a second pivot portion of the nozzle forming a positioning groove. The positioning element is accommodated in the positioning groove and engaged with any one of the positioning holes. Therefore, the positioning element can be engaged with different positioning holes according to the angle of nozzle swing, providing a precise positioning function and preventing the nozzle from swinging arbitrarily during use.

[0011] Preferably, the control shaft of the switching assembly has a flow channel and a water stop portion. The flow channel passes through the control shaft, and the water stop portion is located on one side of the control shaft. When the control shaft is rotated to the first position, the water stop portion is located between the inlet channel and the outlet channel. When the control shaft is rotated to the second position, the flow channel is located between the inlet channel and the outlet channel. Therefore, the water stop portion, as a barrier structure between the inlet channel and the outlet channel, can completely or partially block the area between the second pivot portion and the outlet channel to control the flow rate of the water from the nozzle.

[0012] Preferably, the water-stop section extends through one side of the control shaft, and a water-stop pad is assembled on the water-stop section. Therefore, for example, a separate component can be used to install on the water-stop section, that is, the water-stop pad is used to fill the area of ​​the water-stop section. When the water-stop pad is worn, it can be replaced separately to restore the barrier effect.

[0013] Preferably, the control shaft of the switch assembly has two end caps at both ends, and the actuating member has an operating part and two side holes through which the actuating member engages with the end caps. Therefore, the actuating member drives the control shaft to rotate through the end caps, allowing the control shaft to rotate relative to the first pivot and the second pivot.

[0014] Preferably, the fasteners are made of metal. Therefore, metal fasteners provide a more secure hold, making the connection between the handle and the nozzle less prone to loosening or damage.

[0015] Preferably, the fastener further comprises a connecting structure, one end of which is connected to the first end, and the other end of which is connected to the second end. The first end, the second end, and the connecting structure together form a fastening space. The first pivot portion and the second pivot portion are located within the fastening space, and the first end is fixed between the actuating member and the first pivot portion, while the second end is fixed between the actuating member and the second pivot portion. Therefore, the fastener is located inside the actuating member and directly fixes the first pivot portion and the second pivot portion, thereby achieving a more stable fixing effect.

[0016] Preferably, the outer peripheral surface of the connecting structure is recessed to form a locking groove, and the first pivot portion of the handle extends outward to form a locking portion, which engages with the locking groove. Therefore, the handle and the fastener are interlocked, allowing the fastener to more securely fix the handle and the nozzle.

[0017] Preferably, the first end has a first through hole, the second end has a second through hole, and the control shaft of the switch assembly passes through the first through hole and the second through hole.

[0075] The applicant first clarifies that in the embodiments and accompanying drawings described below, the same reference numerals denote the same or similar elements or their structural features. It should be noted that the elements and structures in the drawings are for illustrative purposes and are not drawn to scale or in quantity; features of different embodiments may be used interchangeably if feasible in practice. Secondly, when it is stated that an element is disposed on another element, it means that the aforementioned element is directly disposed on the other element, or indirectly disposed on the other element; that is, one or more other elements are disposed between the two elements. Conversely, when it is stated that an element is "directly" disposed on another element, it means that no other elements are disposed between the two elements.

[0076] Please see Figures 1 to 8 The adjustable angle water gun 10 provided by the present invention mainly includes a handle 20, a nozzle 30, a switch assembly 40, a fastener 50 and a positioning component 60.

[0077] The handle 20 has a handle body 21, a water inlet 22 and a first pivot portion 23. The water inlet 22 is disposed inside the handle body 21.

[0078] The top of the handle body 21 is provided with a first pivot part 23. The first pivot part 23 has an annular structure and a first through hole 231. The first through hole 231 passes through the first pivot part 23. The first pivot part 23 also forms an inlet 232 that connects to the water inlet channel 22 and an outlet 233 that connects to the nozzle 30.

[0079] The nozzle 30 has a nozzle body 31, a water outlet 32 ​​and a second pivot portion 33.

[0080] The water outlet 32 ​​is located inside the nozzle body 31, and the second pivot part 33 is located at the bottom end of the nozzle 30. The second pivot part 33 has a ring structure. The second pivot part 33 is fitted onto and pivotally connected to the first pivot part 23 of the handle 20, so that the nozzle 30 can pivot relative to the handle 20.

[0081] The second pivot portion 33 has a second through hole 331 that penetrates the second pivot portion 33. The second pivot portion 33 also has an outlet 332 that connects the water outlet 32 ​​and the first pivot portion 23.

[0082] The nozzle 30 and the handle 20 can rotate between a bent state and a flat angle state, and the included angle between them can be from 90 degrees to 180 degrees. The axis of the handle 20 is defined as a first axis X1, and the axis of the nozzle 30 is defined as a second axis X2.

[0083] When the handle 20 and the nozzle 30 are at a flat angle, the angle between the first axis X1 and the second axis X2 can be extended to 180 degrees, such as Figure 1 As shown.

[0084] When the nozzle 30 and the handle 20 are bent, the included angle between the first axis X1 and the second axis X2 is less than 180 degrees, for example... Figure 2 90 degrees and Figure 3 The handle 20 and the nozzle 30 can be bent and positioned arbitrarily within a range of 135 degrees and 90 degrees to 180 degrees.

[0085] A positioning element 60 is provided between the handle 20 and the nozzle 30. The positioning element 60 is a combination of a spring 61 and a steel ball 62. Multiple positioning holes 234 are recessed on the side of the first pivot 23 facing the second pivot 33, and a positioning groove 333 is formed on the side of the second pivot 33 facing the first pivot 23. The positioning element 60 is housed in the positioning groove 333. One end of the spring 61 abuts against the bottom of the positioning groove 333, and the other end protrudes out of the positioning groove 333 and abuts against the steel ball 62.

[0086] As the user rotates the nozzle 30, the steel ball 62 of the positioning member 60 pushes against the spring 61, compressing the spring 61. When the positioning member 60 reaches the other positioning hole 234 of the first pivot part 23, the compressed spring 61 rebounds and pushes the steel ball 62 to engage in the positioning hole 234, thus fixing the rotation angle of the nozzle 30.

[0087] The switch assembly 40 is located between the handle 20 and the nozzle 30, and the switch assembly 40 has a toggle 41 and a control shaft 42.

[0088] The actuating member 41 has an operating part 411 and two side holes 412. The operating part 411 is located between the two side holes 412. The two side holes 412 are formed on the circular plates at both ends of the actuating member 41, and grooves 413 are formed around the side holes 412.

[0089] The control shaft 42 has a flow channel 421 and a water-stopping part 422. The flow channel 421 passes through the control shaft 42, and the water-stopping part 422 passes through one side of the control shaft 42. A water-stopping pad 423 is installed on the water-stopping part 422, so that the water-stopping part 422 and the flow channel 421 change from being interconnected to being disconnected. The water-stopping part 422 can also be a solid structure without the need for the additional water-stopping pad 423.

[0090] Two end caps 424 are also provided at both ends of the control shaft 42. In this embodiment, one end cap 424 is formed at one end of the control shaft 42, and the other end cap 424 is detachably assembled to the other end of the control shaft 42. In this way, the control shaft 42 can first pass through the first through hole 231 of the first pivot portion 23 of the handle 20 and the second through hole 331 of the second pivot portion 33 of the nozzle 30, and then install the end caps 424 to position the control shaft 42 between the handle 20 and the nozzle 30. The inner surfaces of these end caps 424 are all formed with protrusions 425, allowing the actuating member 41 to engage with the protrusions 425 of the end caps 424 through the grooves 413 around the side holes 412, so that the actuating member 41 and the control shaft 42 are in a linked state.

[0091] The fastener 50 is made of metal and has a first end 51, a second end 52 and a connecting structure 53.

[0092] The first end 51 and the second end 52 are located at both ends of the fastener 50. Both the first end 51 and the second end 52 are hollow annular plates. The first end 51 has a first through hole 511 and the second end 52 has a second through hole 521.

[0093] The connecting structure 53 connects the first end 51 and the second end 52. The connecting structure 53 consists of two rectangular plates, each with one end connected to the first end 51 and the other end connected to the second end 52. A recessed groove 531 is formed on the outer periphery of one of the plates. Figure 8 As shown, the first end 51, the second end 52 and the connecting structure 53 together form a fastening space 54, and the first pivot part 23 of the handle 20 extends outward to form a locking part 235.

[0094] When installing the fastener 50, the first pivot portion 23 of the handle 20 is inserted into the fastening space 54 of the fastener 50, and then the second pivot portion 33 of the nozzle 30 is inserted, allowing the second pivot portion 33 to engage with the first pivot portion 23. Simultaneously, the locking portion 235 of the handle 20 engages with the locking groove 531. At this time, the first end 51 of the fastener 50 is located outside the first pivot portion 23 of the handle 20, and the second end 52 is located outside the second pivot portion 33 of the nozzle 30, so that the first pivot portion 23 and the second pivot portion 33 are clamped and tightened by the fastener 50. This increases the structural strength of the connection between the handle 20 and the nozzle 30. Furthermore, since the fastener 50 is made of metal, it can prevent deformation due to high water pressure, resulting in better fixation of the first pivot portion 23 and the second pivot portion 33.

[0095] Next, the control shaft 42 of the switch assembly 40 passes through the first through hole 511, the first through hole 231, the second through hole 331 and the second through hole 521 in sequence. Finally, the toggle member 41 is assembled to the control shaft 42. The first end 51 of the fastener 50 is fixed between the toggle member 41 and the first pivot part 23, and the second end 52 is fixed between the toggle member 41 and the second pivot part 33. The toggle member 41 will also fix the position of the fastener 50 to enhance the fixing effect of the fastener 50.

[0096] Please refer to the following: Figures 9 to 11 When using the water gun 10, the user first connects a water source to the bottom of the handle body 21 of the handle 20, turns on the water source, and lets the water flow into the water channel 22, and then to the first pivot part 23. The toggle member 41 can drive the control shaft 42 to rotate between a first position P1 and a second position P2. The first position P1 represents that the water gun 10 is in the off state, and water cannot be sprayed from the nozzle 30. The second position P2 represents that the water gun 10 is in the on state, and water can be sprayed from the nozzle 30.

[0097] When the actuating member 41 is in the first position P1, the water-stopping pad 423 of the water-stopping part 422 of the control shaft 42 will block the outlet 233 of the first pivot part 23. At this time, the water inlet channel 22 of the handle 20 and the water outlet channel 32 of the nozzle 30 are not connected to each other. The water will remain in the position of the water inlet channel 22 and the first pivot part 23 and cannot flow out from the outlet 233 of the first pivot part 23.

[0098] In addition, since the control shaft 42 has a flow channel 421, water will fill the first through hole 231 through the flow channel 421, and water leakage can be prevented by the sealing ring 70, end cap 424 and fastener 50.

[0099] When the user wants to perform watering operations, they can use the operating part 411 of the actuating part 41 to flip the actuating part 41 upwards, which will drive the control shaft 42 to rotate. When the control shaft 42 rotates to the second position P2, the water stop pad 423 of the control shaft 42 is completely removed from the outlet 233 of the first pivot part 23. The first pivot part 23 is connected to the second pivot part 33. At this time, the water inlet channel 22 of the handle 20 and the water outlet channel 32 of the nozzle 30 are interconnected. The water in the first pivot part 23 will flow from the first pivot part 23 to the second pivot part 33, and then flow through the outlet 332 of the second pivot part 33 to the water outlet channel 32, so that the nozzle 30 can spray out the maximum water output.

[0100] In addition, the user can also adjust the water output. When the control shaft 42 is rotated between the first position P1 and the second position P2, the water stop pad 423 of the control shaft 42 will partially block the outlet 233 of the first pivot 23. Although the first pivot 23 is connected to the second pivot 33, only a portion of the water can pass through the outlet 233 of the first pivot 23 to reduce the amount of water flowing into the water outlet 32. The nozzle 30 will not spray at the maximum water output.

[0101] In summary, the adjustable-angle water gun 10 provided by the present invention has at least the following advantages compared with the prior art:

[0102] 1. The water gun 10 of the present invention has a handle 20 and a nozzle 30 connected by a pivot structure, which allows the nozzle 30 to pivot relative to the handle 20, so that the spraying angle can be changed. Compared with the disadvantage of traditional spraying equipment that cannot adjust the angle, the present invention can increase the convenience of use of the water gun 10.

[0103] 2. The water gun 10 of the present invention uses fasteners 50 to strengthen the fit between the handle 20 and the nozzle 30. The first pivot 23 and the second pivot 33 are arranged inside the fasteners 50 and fixed by clamping. During the use of the water gun 10, water will not leak out from the joint. The fasteners 50 also improve the structural strength of the joint and prevent the first pivot 23 and the second pivot 33 from cracking due to excessive water pressure.

[0104] Finally, it must be stated again that the constituent elements disclosed in the above embodiments of the present invention are merely illustrative examples and are not intended to limit the scope of the present invention. Substitutions or variations of other equivalent elements should also be within the scope of protection of the present invention.
