Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, specifically to a spray gun. Background Technology

[0002] In both daily life and industrial cleaning, spray guns are widely used as a convenient water flow control tool, covering scenarios such as household bathroom cleaning, car washing, garden irrigation, and industrial equipment cleaning. Currently, spray gun products on the market generally suffer from limited functionality, with their core water output method mostly being a fixed shower-style spray, providing only a single type of water flow.

[0003] Traditional spray guns, with their fixed water flow pattern, struggle to adapt to diverse usage needs. When dealing with stubborn stains, the impact of a regular showerhead is insufficient, resulting in low cleaning efficiency. Furthermore, when rinsing fragile items or delicate surfaces, the dispersed water flow and uncontrollable force can easily cause unnecessary damage. In addition, existing spray guns lack specialized water flow designs, failing to achieve the large-area, uniform rinsing or focused, directional cleaning effects of a rotating water flow, significantly limiting their applicability. As users increasingly demand multifunctional and efficient cleaning tools, existing single-function spray guns are no longer sufficient to meet the diverse needs of real-world applications. Utility Model Content

[0004] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, one objective of the present invention is to provide a spray gun with a simple structure that can switch between different water output states according to different usage scenarios.

[0005] To achieve the above objectives, this utility model proposes a spray gun, which includes: The spray gun body includes a handheld part and a water outlet part connected to the handheld part. The handheld part is provided with a water inlet channel, and the water outlet part is provided with a cavity communicating with the water inlet channel, an external water flow channel, and an internal water flow channel. A switching switch includes a rotating shaft and a switching component connected to the rotating shaft. The switching component is provided with a first water passage hole and a second water passage hole. The rotating shaft can drive the switching component to rotate so that the first water passage hole connects the cavity and the external water flow channel, or the second water passage hole connects the cavity and the internal water flow channel. A water outlet assembly, comprising a water outlet panel and a rotating nozzle, wherein the water outlet panel is provided with a first water outlet hole communicating with the external water flow channel, and the rotating nozzle is connected to the internal water flow channel to rotate and spray out the internal water flow channel; The rotating nozzle includes: The cavity has a tapered top with a first water nozzle and an annular limiting groove at the bottom. The annular limiting groove is coaxially arranged with the first water nozzle. The cavity has a first channel and a second channel at the annular limiting groove. Water flows into the annular limiting groove from the first channel and / or the second channel, forming a rotating water flow. A rotating body is freely movably disposed within the cavity. The rotating body is provided with a second water spray nozzle and a water inlet hole communicating with the second water spray nozzle and the cavity. The lower end of the rotating body extends into the annular limiting groove. The rotating water flow inside the cavity can drive the lower end of the rotating body to revolve within the annular limiting groove, and the second spray nozzle can remain in contact with the first spray nozzle to rotate and spray water.

[0006] According to this utility model, a spray gun allows external water to be introduced into a cavity through a water inlet channel. The cavity is switched between an external water flow channel and an internal water flow channel via a switch. When water enters the external water flow channel, the water outlet component sprays water in a shower-like manner; when water enters the internal water flow channel, the rotating nozzle sprays water in a rotating manner. This spray gun has a simple structure and can switch between different water output states according to different usage scenarios.

[0007] In addition, the spray gun proposed according to the embodiments of this utility model may also have the following additional technical features: Optionally, the rotating body has a structure that is large in the middle and small at both ends in its axial direction.

[0008] Furthermore, the water inlet holes are multiple, and the multiple water inlet holes are disposed at the bottom of the middle large-sized part of the rotating body and are spaced apart around the axis of the rotating body.

[0009] Furthermore, the isolation zone between two adjacent water inlets forms a water-blocking section.

[0010] Optionally, the outer peripheral wall of the second water nozzle is configured in a constricted shape along the water flow direction.

[0011] Optionally, both the first channel and the second channel are tangentially connected to the annular limiting groove.

[0016] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0018] The following is for reference. Figure 1-4 The implementation method of the spray gun proposed in the embodiments of this utility model will be described in detail.

[0019] The spray gun according to an embodiment of the present utility model includes: The spray gun body 1 includes a handheld part 11 and a water outlet part 12 connected to the handheld part 11. The handheld part 11 is provided with a water inlet channel 111, and the water outlet part 12 is provided with a cavity 121 communicating with the water inlet channel 111, an external water flow channel 122, and an internal water flow channel 123. The switching switch 2 includes a rotating shaft 21 and a switching component 22 connected to the rotating shaft 21. The switching component 22 is provided with a first water passage hole 221 and a second water passage hole 222. The rotating shaft 21 can drive the switching component 22 to rotate so that the first water passage hole 221 connects the cavity 121 and the external water flow channel 122, or the second water passage hole 222 connects the cavity 121 and the internal water flow channel 123. The water outlet assembly 3 includes a water outlet panel 31 and a rotating nozzle 32. The water outlet panel 31 is provided with a first water outlet hole that communicates with the external water flow channel 122. The rotating nozzle 32 is connected to the internal water flow channel 123 to rotate and spray out the internal water flow channel 123. The rotating nozzle 32 includes: The cavity 323 has a tapered top with a first water nozzle 3211 and an annular limiting groove 3221 at the bottom. The annular limiting groove 3221 is coaxially arranged with the first water nozzle 3211. The cavity 323 has a first channel 3222 and a second channel 3223 at the annular limiting groove 3221. Water flows into the annular limiting groove 3221 from the first channel 3222 and / or the second channel 3223, forming a rotating water flow. Rotating body 324 is freely movable in cavity 323. Rotating body 324 is provided with second water nozzle 3241 and water inlet hole 3242 communicating with second water nozzle 3241 and cavity 323. The lower end of rotating body 324 extends into annular limiting groove 3221. The rotating water flow inside the cavity 323 can drive the lower end of the rotating body 324 to revolve within the annular limiting groove 3221, and the second spray nozzle 3241 can remain in contact with the first spray nozzle 3211 to rotate and spray water.

[0020] In other words, external water enters the cavity 121 of the outlet section 12 from the inlet channel 111 of the handheld part 11. The inner water flow channel 123 and the outer water flow channel 122 are located on one side of the cavity 121. A rotating shaft 21 and a switching element 22 are installed inside the cavity 121. When the rotating shaft 21 rotates, it drives the first water passage 221 and the second water passage 222 on the switching element 22 to rotate. When the first water passage 221 rotates to the state of connecting the cavity 121 and the outer water flow channel, the water in the cavity 121 enters the outer water flow channel 122 and is discharged from the first water outlet of the outlet panel 31 in the form of shower water. When the first water passage 221 rotates to the state of connecting the cavity 121 and the inner water flow channel 123, the water in the cavity 121 enters the inner water flow channel 123, and the water in the inner water flow channel 123 flows from the first channel 3222 and / or the second channel of the rotating nozzle 32. Water is injected into cavity 323 via channel 3223. After entering, the water flows along the annular limiting groove 3221, creating a rotating water flow inside cavity 323. This rotating water flow directly acts on rotating body 324, providing rotational driving force for its rotation. The top of cavity 323 is conical and narrowed. Under the action of the water flow inside cavity 323, rotating body 324 tends to move towards the top of cavity 323, keeping the second spray nozzle 3241 abutting against the first spray nozzle 3211 at the top of cavity 323. At the same time, the annular limiting groove 3221 limits the lower end of rotating body 324, restricting it to rotate within the annular limiting groove 3221. The water inside cavity 323 is ejected through the water inlet 3242 of rotating body 324 via the second spray nozzle 3241, forming a cone-shaped water flow. In this way, users can switch between spray nozzles and rotating spray nozzles using switch 2, depending on the usage scenario. The cavity 323 has a central pillar 3224 protruding from its bottom wall toward the top of the cavity 323. An annular limiting groove 3221 is formed between the outer peripheral wall of the central pillar 3224 and the inner peripheral wall of the cavity 323. The cavity 323 can be formed by connecting the upper shell 321 and the lower shell 322 to facilitate the installation of the rotating body 324. The first water nozzle 3211 is set on the upper shell 321, and the annular limiting groove 3221, the first channel 3222, and the second channel 3223 are set on the lower shell 322. The water inlet 3242 can be set on the side or bottom of the rotating body 324. The diameter of the outer wall of the second water nozzle 3241 can be larger than the diameter of the first water nozzle 3211. A clearance hole for the water nozzle of the rotating nozzle 32 can be set at the center of the water outlet panel 31. The rotating shaft 2 The operating end of 1 can be equipped with a decorative cover 23. Rotating the decorative cover 23 drives the rotating shaft 21 to rotate. The rotating shaft 21 and the cavity 121 can be sealed by a sealing ring. The cavity 121 can be separated from the external water flow channel 122 and the internal water flow channel 123 by a partition. The external water flow channel 122 and the internal water flow channel 123 are coaxially arranged. The first water passage 221 is arranged away from the axis of the switching component 22, and the second water passage 222 is arranged close to the axis of the switching component 22. The partition is provided with water inlets corresponding to the internal water flow channel 123 and the external water flow channel 122. When the first water passage 221 rotates to align with the water inlet of the internal water flow channel 123, water is sprayed from the shower head. When the second water passage 222 rotates to align with the water inlet of the external water flow channel 122, water is sprayed out by rotation.

[0021] Thus, external water is introduced into the cavity 121 through the water inlet channel 111. The cavity 121 is connected to either the external water flow channel 122 or the internal water flow channel 123 by switching the switch 2. When water flows into the external water flow channel 122, the water outlet component 3 sprays water in a shower-like manner. When water flows into the internal water flow channel 123, the water is sprayed out in a rotating manner through the rotating nozzle 32. This spray gun has a simple structure and can switch the water output state according to different usage scenarios.

[0022] Optionally, the rotating body 324 has a structure that is larger in the middle and smaller at both ends in the axial direction. Understandably, the top of the rotating body 324 is used to engage with the tapered constriction at the top of the cavity 323, the middle part of the rotating body 324 is used to engage with the inner wall of the middle part of the cavity 323, and the bottom of the rotating body 324 is used to engage with the annular limiting groove 3221. When the rotating body 324 revolves, the top of the rotating body 324 engaging with the tapered constriction forms a function similar to a rotational fulcrum, and the middle part of the rotating body 324 contacting the inner wall of the cavity 323 provides a supporting abutment, allowing the rotating body 324 to rotate simultaneously with its revolution. This reduces the rotational resistance of the rotating body 324 and improves the smoothness of its rotation. The bottom of the rotating body 324 engaging with the annular limiting groove 3221 restricts the lower end of the rotating body 324 to rotate along a designated path. The cavity 323 and the rotating body 324 are arranged to match the contour of their revolution. The bottom of the rotating body 324 is provided with a limiting post, which is coaxially arranged with the second water nozzle 3241.

[0023] Furthermore, there are multiple water inlet holes 3242, which are located at the bottom of the large central section of the rotating body 324 and spaced apart around the axis of the rotating body 324. Understandably, the large central section of the rotating body 324 provides space for multiple water inlet holes 3242. Distributing these holes around the axis allows the rotating water flow within the annular limiting groove 3221 to enter each water inlet hole 3242 more evenly, avoiding problems such as excessive local pressure or uneven center of gravity distribution caused by concentrated water flow in a single water inlet hole 3242. This reduces jamming caused by uneven force during rotation of the rotating body 324, ensuring stable rotation speed and uniform water flow during showering. Simultaneously, the multiple water inlet hole design improves water intake efficiency, prevents interruptions in water flow due to blockage of a single hole, and ensures the continuity of the shower process.

[0024] Furthermore, the isolation zone between adjacent water inlets 3242 forms a water-blocking section 3243. Understandably, the water-blocking section 3243 serves as the outer wall of the water inlet 3242, and also increases the force of the rotating water flow on the rotating body 324, so that the rotating water flow can more easily drive the rotating body 324 to rotate. The multiple water-blocking sections 3243 are arranged radially.

[0025] Optionally, the outer peripheral wall of the second nozzle 3241 is constricted along the water flow direction. Understandably, by constricting the outer peripheral wall of the second nozzle 3241, the second nozzle 3241 can fit more closely to the inner wall of the first nozzle 3211, reducing the obstruction of the first nozzle 3211 on the second nozzle 3241, increasing the rotation angle of the second nozzle 3241, and achieving a larger range of rotational spray. Specifically, the cavity 323 extends downwards from the first nozzle 3211 with an annular protrusion 3212. The annular protrusion 3212 has a tapered constriction, and the top of the tapered constriction is provided with the second nozzle 3241. The rotating body 324 has a groove 3245 for installing a sealing ring. The groove 3245 abuts against the lower edge of the annular protrusion 3212 to prevent water from entering through the gap between the tapered constriction and the rotating body 324.

[0026] Optionally, both the first channel 3222 and the second channel 3223 are tangentially connected to the annular limiting groove 3221. Understandably, the first channel 3222, with water flowing into it tangentially to the annular limiting groove 3221, minimizes the impact force on the inner and outer walls of the annular limiting groove 3221, allowing water to flow smoothly into the groove and quickly form a rotating water flow. This generates a stable rotating water flow without the need for additional structural guidance, resulting in a simple and reliable structure. The first channel 3222 and the second channel 3223 can be symmetrically distributed with a 180° rotation.

[0027] Optionally, the switch 2 also includes a toggle switch 24, which is connected to the rotating shaft 21 to drive the shaft 21 to rotate. Understandably, the toggle switch 24 allows the user to switch with one hand, making operation convenient and quick. The toggle switch 24 can be designed with a raised structure with anti-slip texture to improve grip and prevent slippage during operation. The toggle switch 24 can also be mounted on the decorative cover 23 for a more aesthetically pleasing overall appearance.

[0028] Optionally, the water outlet panel 31 is threaded to the inner wall of the external water flow channel 122, and the rotating nozzle 32 is partially embedded in the internal water flow channel 123 and threaded to the water outlet panel 31. Understandably, the threaded connection combines a secure connection with easy assembly and disassembly. The threaded connection between the water outlet panel 31 and the external water flow channel 122 facilitates later disassembly and cleaning of scale or impurities inside the external water flow channel 122; the threaded connection between the rotating nozzle 32 and the water outlet panel 31 ensures stable communication with the internal water flow channel 123 and allows for easy replacement of the rotating nozzle 32 component. The threaded connection, used in conjunction with a sealing ring, effectively enhances the sealing of the connection and prevents water leakage.
