Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in high-pressure washers for commercial use that can spray water at relatively high pressures (for example, 2.5 MPa to 14 MPa), if a nozzle with selectable water patterns is used, it is difficult to provide a switchable setting between a high-pressure water pattern and a low-pressure shower pattern.

[0005] Therefore, the present disclosure aims to provide a watering nozzle that can switch between a high-pressure water stream and a low-pressure shower stream. [Means for solving the problem]

[0006] To solve the above problems, a watering nozzle according to a first aspect of the present invention comprises a support member that partitions a water supply channel internally, and a tip member that is positioned downstream of the support member and rotatably supported by the support member, having a plurality of nozzle sections formed to spray water in different water patterns, wherein the tip member can switch the flow path of water from the supply channel to spray water from any of the plurality of nozzle sections depending on its rotational position relative to the support member, the plurality of nozzle sections include a high-pressure nozzle section and a shower nozzle section, the high-pressure nozzle section has a flow path that narrows toward the discharge port at the tip and forms a straight, fan-shaped, or conical water pattern, and the shower nozzle section has a pressure-reducing wall spaced apart from the tip opening of the supply channel of the support member and facing the tip opening, and a shower spray plate section at the tip provided with a plurality of holes.

[0007] A second aspect of the present invention is a watering nozzle according to the first aspect, comprising a connecting portion provided on the upstream side of the support member, wherein the connecting portion is detachable from a high-pressure washer having a pump.

[0008] A third aspect of the present invention is a watering nozzle according to the first or second aspect, wherein an internal space with a cross-sectional area larger than the tip opening of the supply channel of the support member is provided on the upstream side of the shower spraying plate portion.

[0009] A fourth aspect of the present invention is a watering nozzle according to the first or second aspect, wherein the tip member is provided with an elastic cover that covers the surface in a state that allows water to be sprayed. [Effects of the Invention]

[0010] According to this disclosure, it is possible to provide a watering nozzle that can switch between a high-pressure water stream and a low-pressure shower stream. [Brief explanation of the drawing]

[0011] [Figure 1] This is a side view of a watering nozzle according to one embodiment of the present invention. [Figure 2] Figure 1 is a perspective view of a watering nozzle. [Figure 3] This is a front perspective view of the main part of the watering nozzle. [Figure 4] This is a cross-sectional view taken along the line IV-IV in Figure 3. [Figure 5] This is a cross-sectional view corresponding to Figure 4, showing the state where the fourth nozzle section is selected. [Modes for carrying out the invention]

[0012] An embodiment of the present invention will be described below with reference to the drawings. In each figure, the X direction indicates the direction of water spraying, the direction indicated by the X arrow is the downstream side of the water flow direction, and the direction opposite to the direction indicated by the X arrow is the upstream side of the water flow direction. Also, CL indicates the rotation axis (axis center) of the rotating head.

[0013] Figure 1 is a side view of a watering nozzle according to one embodiment of the present invention. Figure 2 is a perspective view of the watering nozzle of Figure 1. Figure 3 is a front perspective view of the main part of the watering nozzle. Figure 4 is a cross-sectional view taken along the line IV-IV in Figure 3. Figure 5 is a cross-sectional view corresponding to Figure 4, showing the state in which the fourth nozzle section is selected. Figures 1 to 4 show the state in which the second nozzle section, which will be described later, is selected.

[0014] The watering nozzle 10 according to this embodiment is installed at the tip of a high-pressure washer (such as a commercial high-pressure washer) capable of spraying water at relatively high pressure (e.g., 2.5 MPa to 14 MPa). The high-pressure washer (not shown) of this embodiment is a rechargeable, handheld type washer and has a pump (not shown) driven by an electric motor powered by a battery. The discharge pressure of the pump is, for example, 2.5 MPa to 14 MPa. Note that the high-pressure washer with a pump is not limited to a rechargeable type, and may be a wired type that can be connected to a power source (such as a household power supply).

[0015] As shown in Figures 1 and 2, the watering nozzle 10 of this embodiment has a rotating head portion (tip member) 40 and a head support portion (support member) 20 that rotatably supports the rotating head portion 40, and is a watering nozzle 10 that can switch between multiple different water patterns for watering. In addition to the above, the watering nozzle 10 of this embodiment also has a lance 11, which is a straight extension pipe that divides a flow path inside, a flexible joint 12 provided at the downstream end of the lance 11 to support the head support portion 20, and a connecting portion 13 provided at the upstream end of the lance 11. That is, the connecting portion 13 is provided on the upstream side of the head support portion 20. The flexible joint 12 supports, for example, the ball joint 23 of the head support portion 20, which will be described later, so that its angle and orientation can be changed. The connecting portion 13 is a connecting portion that can be attached to and detached from the high-pressure washer.

[0016] In this embodiment, a lance 11 is integrally provided on the watering nozzle 10, and a connecting portion 13 is provided on the upstream end of the lance 11, but the invention is not limited to this. For example, the connecting portion 13 may be directly provided on the head support portion (support member) 20 of the watering nozzle 10 without going through the flexible joint 12 and the lance 11. Also, in this embodiment, a watering nozzle 10 having a connecting portion 13 that can be attached to and detached from a high-pressure washer is described, but the invention is not limited to this, and a watering nozzle may be integrally provided on the tip of the high-pressure washer without having a connecting portion 13.

[0017] As shown in FIGS. 3 and 4, the head support portion 20 has, for example, a main body portion 21, a tubular member 22, a ball joint 23, and a positioning mechanism 24.

[0018] As shown in FIG. 4, the main body portion 21 is, for example, a resin member, and a cross-section orthogonal to the X direction is formed in a circular shape. A support shaft insertion hole 25 extending linearly along the X direction is provided at the center of the main body portion 21. The support shaft insertion hole 25 penetrates the main body portion 21 along the X direction with the rotation axis CL, which is the rotation center of the rotary head portion 40, as the center. The support shaft insertion hole 25 is formed to have a size that allows the insertion of a support shaft 44, which will be described later. A tubular member insertion hole 26 extending linearly in the X direction is provided at a position eccentric from the center portion (support shaft insertion hole 25) of the main body portion 21. The tubular member insertion hole 26 penetrates the main body portion 21 along the X direction. The tubular member insertion hole 26 is formed to have a size and shape into which a tubular member 22, which will be described later, fits. Also, a positioning member accommodation portion 27 opening toward the outer side in the radial direction is provided at a position on the opposite side of the tubular member insertion hole 26 across the support shaft insertion hole 25 of the main body portion 21 in the radial direction. The positioning member accommodation portion 27 is a hole extending toward the outer side in the radial direction, having a bottom in the vicinity of the support shaft insertion hole 25 and opening toward the outer side in the radial direction. The positioning mechanism 24, which will be described later, is accommodated in the positioning member accommodation portion 27.

[0019] A stepped portion 21a is provided on the outer peripheral surface of the main body portion 21 along the circumferential direction. Among the main body portion 21, the upstream side of the stepped portion 21a is a large-diameter portion 21b, and the downstream side of the stepped portion 21a is a small-diameter portion 21c having a smaller diameter than the large-diameter portion 21b. The positioning member accommodation portion 27 opens to the outer peripheral surface of the small-diameter portion 21c.

[0020] As shown in FIG. 4, the positioning mechanism 24 includes a ball member 32 accommodated in the positioning member accommodation portion 27 and a biasing member 33 that biases the ball member 32 toward the outer side in the radial direction. The ball member 32 is provided so as to be able to be exposed from the outer peripheral surface of the small-diameter portion 21c of the main body portion 21.

[0021] As shown in FIG. 4, the tubular member 22 is, for example, a metal member that defines a water supply passage 28 therein, and is fitted into the tubular member insertion hole 26 of the main body portion 21 and supported by the main body portion 21. That is, the head support portion (support member) 20 defines the water supply passage 28 therein. The downstream end of the tubular member 22 is disposed substantially at the same position in the X direction as the downstream opening of the tubular member insertion hole 26 of the main body portion 21. The upstream end of the tubular member 22 protrudes from the upstream opening of the tubular member insertion hole 26 of the main body portion 21. A tip opening 28a of the supply passage 28 is provided at the downstream end of the tubular member 22. A ball joint 23 is provided at the upstream end of the tubular member 22. The ball joint 23 is rotatably supported by a flexible joint 12 provided at the downstream end of the lance 11. In this embodiment, the tubular member 22 that defines the supply passage 28 is provided in the head support portion 20, but the present invention is not limited thereto. For example, the supply passage 28 may be directly defined and formed in the main body portion 21 without providing the tubular member 22.

[0022] A pressure contact member 29 for preventing the occurrence of a gap between the downstream end of the tubular member 22 of the present embodiment and the rotary head portion 40 is provided. The pressure contact member 29 is disposed in the supply passage 28 at the downstream end of the tubular member 22. The pressure contact member 29 is formed in a cylindrical shape penetrating in the X direction and allows the flow of water from the upstream side to the downstream side with respect to the pressure contact member 29. A seal member 30 such as an O-ring for suppressing the occurrence of a gap between the outer peripheral surface of the pressure contact member 29 and the inner peripheral surface of the tubular member 22 is provided. An urging member 31 such as a spring is provided on the upstream side of the pressure contact member 29 to urge the pressure contact member 29 toward the downstream side. The pressure contact member 29 is urged toward the downstream side by the urging member 31 and is pressure contacted to the upstream end face of the rotary head portion 40.

[0023] As shown in Figure 3, the rotating head 40 has a plurality of nozzle sections (nozzle sections 41A to 41D, described later) that are formed to spray water in different patterns, and is positioned downstream of the head support section 20 and rotatably supported by the head support section 20. Depending on the rotational position of the rotating head 40 relative to the head support section 20, the water flow path from the supply channel 28 of the head support section 20 can be switched to spray water from one of the plurality of nozzle sections, described later. In the following description, the rotation of the rotating head 40 means rotation around the rotation axis CL relative to the head support section 20.

[0024] As shown in Figure 3, the rotating head portion 40 of this embodiment is formed such that, when the watering surface 40a (front) is viewed from the front, a smaller circle is formed relative to a larger circle centered on the rotation axis CL, with a part of the smaller circle protruding outward from the outer edge of the larger circle. That is, the outer edge of the watering surface 40a of the rotating head portion 40 includes a large-diameter large circular portion 40b and a smaller circular portion 40c with a smaller diameter than the large circular portion 40b. The smaller circular portion 40c protrudes radially outward from the virtual circle formed by the large circular portion 40b (the virtual circle shown by the dashed line a in Figure 3). That is, the virtual circle formed by the large circular portion 40b (the virtual circle shown by the dashed line a in Figure 3) and the virtual circle formed by the smaller circular portion 40c (not shown) partially overlap. Note that the virtual circle of the large circular portion 40b shown by the dashed line a in Figure 3 is shown slightly smaller for clarity.

[0025] As shown in Figures 3 to 5, the rotating head portion 40 is made of, for example, a resin material, and its upstream side in the X direction is formed in a concave shape to allow insertion of the small-diameter portion 21c of the head support portion 20. That is, the rotating head portion 40 has a recess 47 into which the small-diameter portion 21c of the head support portion 20 can be inserted. The recess 47 is formed in a circular shape centered on the rotation axis CL. The inner circumferential surface of the recess 47 faces the outer circumferential surface of the small-diameter portion 21c of the head support portion 20. The inner circumferential surface of the recess 47 is provided with a plurality of spherical locking recesses (not shown) capable of locking the ball member 32 of the positioning mechanism 24 of the head support portion 20. The plurality of locking recesses are positioned to lock the ball member 32 of the positioning mechanism 24 when the four nozzle portions 41A to 41D, described later, are positioned in a rotation position (usage position) where water can be sprayed.

[0026] The rotating head portion 40 has a through hole 43 that penetrates in the X direction through the center of the large circular portion 40b (the portion including the rotation axis CL). The rotating head portion 40 and the head support portion 20 are rotatably connected to each other by a support shaft 44 that passes through the through hole 43 of the rotating head portion 40 and the support shaft insertion hole 25 of the head support portion 20, and a nut 45 fixed to the support shaft 44.

[0027] As shown in Figures 3 to 5, for example, the rotating head unit 40 of this embodiment has four nozzle units 41A to 41D that are formed to spray water in different water patterns. The four nozzle units 41A to 41D are arranged at different positions in the circumferential direction on the rotating head unit 40. For example, the first nozzle unit (high-pressure nozzle unit) 41A, the second nozzle unit (high-pressure nozzle unit) 41B, and the third nozzle unit (high-pressure nozzle unit) 41C among the multiple nozzle units 41A to 41D are capable of spraying water at high pressure in a fan-shaped water pattern, and the spray angles of the fan-shaped water patterns are different from each other. The fourth nozzle unit (shower nozzle unit) 41D sprays water in a shower-like pattern at a lower pressure (e.g., atmospheric pressure) than the first nozzle units 41A to the third nozzle units 41C. Note that the combination of multiple nozzle units is not limited to the above, and it is sufficient to include at least one high-pressure nozzle unit and a shower nozzle unit. In this specification, "low pressure" refers to a pressure that is relatively low to the high-pressure nozzle unit that sprays at high pressure, and includes atmospheric pressure.

[0028] As shown in Figure 4, the first nozzle section 41A to the third nozzle section 41C have a flow path 48 that narrows toward the water outlet 42 at the tip, and are high-pressure nozzle sections that can spray water at high pressure by restricting the water supplied from the pump of the high-pressure washer at the tip. The flow paths 48 of the first nozzle section 41A to the third nozzle section 41C communicate with the supply flow path 28 of the head support section 20 at a predetermined rotation position (hereinafter referred to as the "operating position"). Figure 4 shows the state in which the flow path 48 of the second nozzle section 41B communicates with the supply flow path 28 of the head support section 20. Although Figure 4 shows a cross-section of the second nozzle section 41B, the first nozzle section 41A and the third nozzle section 41C are the same in that they have a flow path 48 that narrows toward the water outlet 42 at the tip, although the size of the water outlet 42 at the tip (radial length in this embodiment) is different.

[0029] For example, the first nozzle section 41A to the third nozzle section 41C are formed such that, at their respective sprayable usage positions, the fan-shaped water pattern expands vertically (radially around the rotation axis CL). Each of the first nozzle section 41A to the third nozzle section 41C is a nozzle section with a fixed central angle (spray angle) of the fan shape, and is not linearly (at a constant ratio) changeable. The spray angles of the first nozzle section 41A to the third nozzle section 41C are different from each other and may be angles selected from, for example, 7 degrees, 15 degrees, 35 degrees, 55 degrees, etc. "Fan-shaped water pattern" means a water pattern that spreads in the vicinity of the spraying surface 40a. Also, the spray angle means the angle of spread of the water pattern that spreads from the spraying surface 40a. In this embodiment, the water flow pattern of the first nozzle section 41A to the third nozzle section 41C is a fan shape that spreads vertically (radially around the rotation axis CL), but it is not limited to this, and may be a fan shape that spreads horizontally (in a direction perpendicular to the radial direction). Also, the water flow pattern of the first nozzle section 41A to the third nozzle section 41C is not limited to a fan shape, but may be a straight or conical water flow pattern, or a combination thereof.

[0030] As shown in Figure 5, the fourth nozzle section 41D has a pressure reducing wall 49 that is spaced apart from the tip opening 28a of the supply channel 28 of the head support section 20 and faces the tip opening 28a in the usage position, a pressure reducing chamber (internal space) 50 with a cross-sectional area larger than the tip opening 28a, and a shower spray plate section 51 downstream of the pressure reducing chamber 50.

[0031] A smaller pre-chamber 53 is provided between the pressure-reducing wall 49 and the tip opening 28a of the supply channel 28 of the head support section 20. The radially outer side of the pre-chamber 53 communicates with the pressure-reducing chamber 50. The pressure-reducing chamber 50 is a space with a larger cross-sectional area (cross-sectional area perpendicular to the X direction) than the tip opening 28a of the supply channel 28. The downstream side of the pressure-reducing chamber 50 is covered by a shower spray plate section 51. The shower spray plate section 51 is a plate positioned on the rotating head section 40 with a water spraying surface 40a, and has a plurality of holes 51a for spraying water in a shower-like manner. That is, a pressure-reducing chamber 50 with a larger cross-sectional area than the tip opening 28a of the supply channel 28 is provided on the upstream side of the shower spray plate section 51.

[0032] When the fourth nozzle section 41D is positioned for use, water from the tip opening 28a of the supply channel 28 of the head support section 20 flows into the front chamber 53 of the rotating head section 40, collides with the depressurizing wall 49 and is depressurized. Subsequently, it is depressurized further in the wide depressurizing chamber 50 and sprayed in a low-pressure shower-like manner from multiple holes 51a of the shower spray plate section 51.

[0033] In this embodiment, the shower spray plate portion 51 of the fourth nozzle portion 41D is formed in a circular shape concentric with the small circular portion 40c of the spray surface 40a when viewed from the front, and a portion of it is located inside the virtual circle formed by the large circular portion 40b (the virtual circle shown by the dashed line a in Figure 3). That is, at least a portion of the fourth nozzle portion 41D is located within the small circular portion 40c, which is outside the virtual circle formed by the large circular portion 40b (the virtual circle shown by the dashed line a in Figure 3).

[0034] As shown in Figures 3 to 5, the rotating head portion 40 of this embodiment is provided with an elastic cover 46. The cover 46 is made of a soft resin (for example, silicone, TPE (Thermoplastic Elastomer), NBR (Nitrile Butadiene Rubber), etc.) and covers the outer circumferential surface of the rotating head portion 40. That is, the cover 46 is attached in a state where the water spraying surface 40a of the rotating head portion 40 is open, and covers the surface in a state that allows water to be sprayed. The tip of the cover 46 protrudes forward of the water spraying surface 40a of the rotating head portion 40. The tip of the cover 46 that protrudes forward of the water spraying surface 40a of the rotating head portion 40 is located at the very front of the water spraying nozzle 10.

[0035] In the watering nozzle 10 configured as described above, high-pressure water is supplied from the pump of the high-pressure washer to the supply channel 28 of the head support section 20. The first nozzle section 41A to the third nozzle section 41C have a channel 48 that narrows towards the water outlet 42 at the tip, and are high-pressure nozzle sections that can spray water at high pressure by restricting the water sent from the pump of the high-pressure washer at the tip. Therefore, when the first nozzle section 41A to the third nozzle section 41C are positioned in the usage position, the high-pressure water supplied from the pump of the high-pressure washer can be further pressurized by the narrowing channel 48 and sprayed.

[0036] Furthermore, the fourth nozzle section (shower nozzle section) 41D has a pressure-reducing wall 49 that is spaced apart from and facing the tip opening 28a of the supply channel 28 of the head support section 20, and a shower spray plate section 51 on the downstream side of the pressure-reducing chamber 50. Therefore, when the fourth nozzle section 41D is positioned for use, the high-pressure water supplied from the pump of the high-pressure washer is reduced in pressure as it hits the pressure-reducing wall 49 from the tip opening 28a. This allows the water supplied from the pump to be sprayed from the fourth nozzle section 41D as a low-pressure shower stream.

[0037] Furthermore, the rotating head unit 40 can be switched to spray water from the supply channel 28 through any of the nozzles from the first nozzle unit 41A to the fourth nozzle unit 41D, depending on its rotational position relative to the head support unit 20.

[0038] Thus, according to this embodiment, it is possible to provide a watering nozzle 10 that can switch between a high-pressure water stream and a low-pressure shower stream.

[0039] Furthermore, a pressure reduction chamber 50 with a larger cross-sectional area than the tip opening 28a of the supply channel 28 of the head support section 20 is provided upstream of the shower spray plate section 51. Therefore, when the fourth nozzle section 41D is positioned for use, the high-pressure water supplied from the pump of the high-pressure washer hits the pressure reduction wall 49 from the tip opening 28a and then flows into the wide pressure reduction chamber 50. This allows the water supplied from the pump to be sprayed from the fourth nozzle section 41D as a lower-pressure shower stream.

[0040] Furthermore, the watering nozzle 10 is equipped with a connection part that can be attached to and detached from a high-pressure washer having a pump. For this reason, for example, as in this embodiment, the watering nozzle 10 can be equipped with a lance 11, or it can be equipped with a watering nozzle 10 that can be connected directly or indirectly to a high-pressure washer without a lance 11.

[0041] Furthermore, since the head support portion 20 is provided with an elastic cover 46, it is possible to prevent scratches on the vehicle body when the head support portion 20 comes into contact with the vehicle body, for example, during car washing.

[0042] The present invention has been described above based on the above embodiments. However, the present invention is not limited to the contents of the above embodiments, and can naturally be modified as appropriate without departing from the present invention. In other words, all other embodiments, examples, and operational techniques made by those skilled in the art based on these embodiments are, of course, included in the scope of the present invention.
