Description

Technical Field

[0001] This utility model relates to the field of spray accessory technology, and in particular to a spray head. Background Technology

[0002] A sauna (also known as a dry sauna) is a facility that uses a high-temperature environment to achieve health and wellness functions. It uses a heating device to heat sauna stones to a high temperature. When water is poured onto the surface of the hot sauna stones, the water vaporizes rapidly upon contact with the heat, instantly generating a large amount of steam. This steam increases indoor humidity, thereby raising the perceived temperature of the human body and achieving effects such as promoting blood circulation and relieving fatigue.

[0003] In actual use of sauna rooms, pouring water onto the sauna stones is primarily done manually. Users need to use a spoon to scoop an appropriate amount of water from a container and then pour it onto the hot sauna stones. This process requires manual operation, which interrupts the user's sauna experience and affects comfort.

[0004] To address this issue, a small number of sauna rooms are equipped with automatic watering systems. These systems typically consist of a water supply unit, sprinklers, and a controller. The controller, based on a preset program or user instructions, controls the water supply unit to deliver a measured amount of water to the sprinklers, which then spray the water onto the high-temperature sauna stones, thus automating and quantifying the watering process. No manual intervention from the user is required.

[0005] However, due to the high temperature inside the sauna, the showerheads and the pipes connecting them to the water supply system are continuously heated. This causes residual moisture or air inside the pipes to expand. The expanded moisture and air create a thrust, pushing the residual water towards the showerhead's outlet, eventually causing it to flow out naturally. This results in a "dripping" phenomenon when the equipment is not in operation. If these dripping water droplets come into contact with the high-temperature sauna stones, they will irregularly generate additional steam, further affecting the user's comfort.

[0006] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0007] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a nozzle that aims to solve the problem of water dripping when the nozzle is heated in the prior art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A nozzle, comprising: The nozzle body has an inlet channel, an outlet channel and a buffer chamber inside. The inlet channel is vertically arranged and the top of the inlet channel and the end of the outlet channel are connected to the buffer chamber. The water inlet pipe is installed on the nozzle body and is connected to the water inlet channel; The nozzle is installed on the nozzle body and is connected to the water outlet channel.

[0009] Furthermore, the water inlet channel has an L-shaped structure, including a vertical section and a horizontal section. The vertical section is perpendicular to the buffer chamber, and the horizontal section is connected to the water inlet pipe.

[0010] Furthermore, the inner diameter of the horizontal segment is larger than the inner diameter of the vertical segment.

[0011] Furthermore, it also includes a cover; the top of the nozzle body is provided with a countersunk hole, the cover is installed on the countersunk hole, and its bottom and the countersunk hole enclose to form the buffer cavity; a sealing ring is provided between the peripheral wall of the cover and the inner wall of the countersunk hole.

[0012] Furthermore, a first annular groove is formed on the peripheral wall of the cover, and a set screw that can extend into the first annular groove is screwed onto the peripheral wall of the nozzle body.

[0013] Furthermore, a first mounting cavity is provided at the bottom of the nozzle body, the nozzle is screwed into the first mounting cavity, and the bottom of the nozzle is flush with the bottom of the nozzle body.

[0014] Furthermore, the nozzle has at least two water outlet sections sequentially opened in the axial direction, and the inner diameter of each water outlet section gradually decreases in the direction away from the water outlet channel.

[0015] Furthermore, two inclined guide vanes are provided in the uppermost water outlet section, with the middle of the two guide vanes connected to each other; on the vertical projection plane, the two guide vanes intersect; the gap between the two guide vanes on opposite sides forms a water passage.

[0016] Beneficial effects: This utility model provides a nozzle with a vertically arranged water inlet channel that is connected to a buffer chamber, forming a water flow path where "water flows upward from the inlet pipe to the buffer chamber, and then downward to the nozzle." In the non-working state, even if the high temperature in the sauna causes residual water or air to expand due to heat, the expansion force cannot push the residual water upward to the top of the inlet channel and into the buffer chamber, nor will it flow out of the nozzle through the outlet channel. This effectively avoids water dripping from the nozzle in the non-working state, prevents water droplets from contacting the high-temperature sauna stone and generating disordered extra steam, and improves user comfort.

Detailed Implementation

[0019] This utility model provides a nozzle. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0021] Please see Figures 1 to 5 As shown in the figure, this utility model provides a sprinkler head, which is connected to a water supply device via a pipe. The water supply device is existing technology and mainly serves to provide a quantitative water supply; however, the water supply device is not shown in the accompanying drawings. Specifically, the water supply device can adopt one of two structures: one includes a water pipe with a solenoid valve between it and the pipe connecting the sprinkler head, allowing for quantitative water supply by controlling the opening and closing of the solenoid valve; the other includes a water storage tank and a water pump, which pumps water from the storage tank into the pipe connecting the sprinkler head, also achieving quantitative water supply to the sprinkler head. It should be noted that the specific structure and working principle of the water supply device are not within the scope of protection of this utility model, therefore, their specific structure and working principle will not be described in detail.

[0022] The nozzle includes a nozzle body 1, a water inlet pipe 2, and a nozzle 3. The nozzle body 1 has a water inlet channel 11, a water outlet channel 12, and a buffer chamber 13. The water inlet channel 11 is vertically arranged, and the top of the water inlet channel 11 and the end of the water outlet channel 12 are connected to the buffer chamber 13. The water inlet pipe 2 is installed on the nozzle body 1 and is connected to the water inlet channel 11. The nozzle 3 is installed on the nozzle body 1 and is connected to the water outlet channel 12.

[0023] When water is supplied, water enters the vertically arranged water inlet channel 11 through the water inlet pipe 2, flows upward along the water inlet channel 11 to the buffer chamber 13, and then flows from the buffer chamber 13 to the water outlet channel 12, finally spraying through the nozzles 3. After the water supply stops, the water remaining in the water inlet channel 11 settles at the bottom of the water inlet channel 11 and inside the water inlet pipe 2 due to its own weight. Even if the high temperature in the sauna causes the residual water or air to expand due to heat, the expansion force is insufficient to push the residual water upward to the top of the water inlet channel 11 and into the buffer chamber 13, and it cannot flow out from the nozzles 3 through the water outlet channel 12, thus achieving the purpose of preventing dripping. Through the above settings, dripping from the nozzles is effectively avoided when the nozzles are not in operation, thereby preventing the dripping water droplets from contacting the high-temperature sauna stones and generating disordered extra steam, ensuring stable temperature and humidity in the sauna, improving user comfort, and the simple structural design can be stably adapted to automatic watering equipment in saunas.

[0024] In a preferred embodiment, see [reference] Figure 4 The water inlet channel 11 has an L-shaped structure and includes a vertically arranged vertical section 111 and a horizontal section 112. The vertical section 111 is perpendicular to the buffer chamber 13, and the horizontal section 112 is connected to the water inlet pipe 2. With the above arrangement, the water inlet pipe 2 is perpendicular to the nozzle body 1. Through the water inlet pipe 2 with a specific length design, the nozzle body 1 and the nozzle 3 connected to the nozzle body 1 can be extended together to the center above the sauna stone, so that the spray range of the nozzle 3 can cover the entire sauna stone and improve the uniformity of steam generation.

[0025] Further, see Figure 4 The inner diameter of the horizontal section 112 is larger than the inner diameter of the vertical section 111; specifically, the inner diameter of the inlet pipe 2 is larger than the inner diameter of the horizontal section 112, forming a gradually changing inner diameter structure. According to the principles of fluid mechanics, when fluid flows in a closed channel, the smaller the cross-sectional area, the greater the flow velocity; when water enters the horizontal section 112 from the inlet pipe 2, the flow velocity initially increases due to the reduced inner diameter; when it enters the vertical section 111 with an even smaller inner diameter, the flow velocity further accelerates. Through the above arrangement, the pressure energy of the water supply can be efficiently converted into kinetic energy, allowing the water to flow upward along the vertical section 111 at a faster speed to the buffer chamber 13, providing stable kinetic energy for the subsequent entry from the buffer chamber 13 into the outlet channel 12 and finally spraying through the nozzle 3, ensuring the uniformity of the spray.

[0026] Preferably, the nozzle body 1 has a second mounting cavity 15 coaxially arranged with the horizontal section 112, and the end of the water inlet pipe 2 is connected to the second mounting cavity 15 by a thread to achieve a stable fixation between the water inlet pipe 2 and the nozzle body 1.

[0027] Preferably, see Figure 3 , 4 A first rubber gasket 6 is provided between the water inlet pipe 2 and the inner bottom of the second mounting cavity 15 to improve the sealing between the water inlet pipe 2 and the nozzle body 1 and prevent liquid from leaking from the gap where the two are connected.

[0028] In a preferred embodiment, see [reference] Figure 3 , 4 The system also includes a cover 4; the top of the nozzle body 1 is provided with a countersunk hole, and the cover 4 is installed on the countersunk hole, with its bottom enclosing the countersunk hole to form the buffer cavity 13; through the above configuration, there is no need to directly process complex chamber structures inside the nozzle body 1, and the buffer cavity 13 can be formed inside the nozzle body 1 more conveniently, reducing the processing difficulty and cost of the nozzle body 1. Specifically, the cover 4 and the countersunk hole are detachably connected. After long-term use, scale or impurities are prone to accumulate inside the buffer cavity 13. During cleaning, the cover 4 can be removed to clean and maintain the inside of the buffer cavity 13, avoiding blockage of the connection between the water inlet channel 11 and the buffer cavity 13, and the water outlet channel 12 and the buffer cavity 13, ensuring the smooth water supply of the nozzle and adapting to the long-term use needs of the automatic watering equipment in the sauna.

[0029] A sealing ring 5 is provided between the peripheral wall of the cover 4 and the inner wall of the countersunk hole. By setting the sealing ring 5, the sealing performance of the buffer cavity 13 is effectively enhanced, preventing water in the buffer cavity 13 from leaking out from the gap between the cover 4 and the countersunk hole. Specifically, a second annular groove 43 is formed on the peripheral wall of the cover 4, and the sealing ring 5 is an O-ring with good elasticity. The sealing ring 5 is embedded in the second annular groove 43. The elasticity of the O-ring itself allows it to fit tightly against the peripheral wall of the cover 4 and the inner wall of the countersunk hole, further filling the tiny gap between them and minimizing the risk of leakage.

[0030] Further, see Figure 3 , 4 The cover 4 has a first annular groove 41 on its peripheral wall, specifically, the first annular groove 41 is located above the second annular groove 43; the nozzle body 1 has a set screw 42 screwed into its peripheral wall, which can extend into the first annular groove 41. The cooperation between the first annular groove 41 and the set screw 42 defines the axial position of the cover 4, ensuring that the cover 4 is installed stably and is easy to install and remove.

[0031] Preferably, see Figure 3 , 4The top of the cover 4 is provided with a flange 44 extending in the horizontal direction. The flange 44 and the set screw 42 work together to restrict the axial movement of the cover 4. The top of the flange 44 is flush with the top of the nozzle body 1, which improves the overall appearance of the nozzle.

[0032] In this embodiment, the water outlet channel 12 is vertically arranged, and the top of the water outlet channel 12 is connected to the buffer chamber 13. Through the above arrangement, the external dimensions of the nozzle body 1 can be reduced accordingly.

[0033] In the above embodiments, see Figure 3 , 4 The nozzle body 1 has a first mounting cavity 14 at its bottom, and the nozzle 3 is screwed into the first mounting cavity 14, with the bottom of the nozzle 3 flush with the bottom of the nozzle body 1. By embedding the nozzle 3 into the first mounting cavity 14, a hidden mounting structure is formed, giving the bottom of the nozzle body 1 a flat and simple appearance, further enhancing the aesthetics of the nozzle.

[0034] Preferably, a second rubber gasket 7 is provided between the top of the nozzle 3 and the top of the first mounting cavity 14 to improve the sealing between the nozzle 3 and the nozzle body 1 and prevent liquid from leaking from the gap where the two are connected.

[0035] Preferably, see Figure 2 The nozzle 3 has two symmetrically arranged blind holes 34 at its bottom. A tool can be inserted into the blind holes 34 to rotate the nozzle 3, so as to achieve portable assembly and disassembly of the nozzle 3 and the first mounting cavity 14.

[0036] The tool includes a connecting rod and two positioning pins mounted on the connecting rod, each positioning pin being inserted into a corresponding blind hole 34. When the two positioning pins are inserted into the two blind holes 34 respectively, they provide a stable point of force for rotation, preventing tool slippage and operational inconvenience. It should be noted that this tool is not within the scope of this utility model. This utility model only provides a feasible solution for tool adaptation regarding the connection structure between the nozzle 3 and the nozzle body 1, and does not limit the specific structure of the tool. Furthermore, the tool is not shown in the accompanying drawings. In practical applications, different types of tools can be flexibly adapted according to the specific size, shape, and other structural features of the blind hole 34 to meet the needs of nozzle 3 assembly and disassembly.

[0037] In a preferred embodiment, see [reference] Figure 4The nozzle 3 has at least two water outlet sections 31 sequentially arranged along the axial direction, and the inner diameter of each water outlet section 31 gradually decreases along the direction away from the water outlet channel 12. In this embodiment, the water outlet section 31 consists of three sections, which are sequentially spliced ​​together to form the water outlet hole of the nozzle 3. The design of the water outlet hole gradually decreasing in outer diameter along the water flow direction can accelerate the water flow velocity by means of fluid mechanics principles, ensuring that the water supply can act on the target area of ​​the sauna stone in a stable water flow pattern.

[0038] Further, see Figure 4 , 5 The uppermost water outlet section 31 contains two inclined guide vanes 32, which are connected at their midpoints. On the vertical projection plane, the two guide vanes 32 intersect, specifically at an angle of 90°. The gap between the opposite sides of the two guide vanes 32 forms a water passage channel 33. When water enters the uppermost water outlet section 31, it is guided by the two inclined and intersecting guide vanes 32 into the water passage channel 33. Due to the inclination angle of the guide vanes 32, the water flow gains a circumferential deflection force as it passes through the water passage channel 33. Combined with the velocity advantage brought by the gradual change in the overall inner diameter of the water outlet, the water flow spreads evenly circumferentially after being sprayed from the water outlet, ultimately forming a solid cone spray shape with controllable coverage. This spray pattern allows all areas of the sauna stone to be evenly contacted by the water flow, resulting in more balanced heating and steam generation on the sprayed sauna stone.

[0039] In summary, this utility model connects the water inlet channel 11 and the water outlet channel 12 to the buffer chamber 13, forming a water flow path where "water first flows upward from the water inlet pipe 2 to the buffer chamber 13, and then downward to the nozzle 3." In the non-working state, residual water in the water inlet pipe 2 will not flow to the nozzle due to heat, thus achieving a drip-proof function. Simultaneously, the water inlet channel 11 adopts an L-shaped structure, making the water inlet pipe 2 and the nozzle body 1 perpendicular to each other, allowing the nozzle 3 to be positioned above the center of the sauna stone. Combined with the guide vane 32 built into the nozzle 3, the flowing water receives a circumferential deflection force, ultimately forming a solid cone spray shape with controllable coverage, ensuring that the water flow evenly covers the conventional placement area of ​​the sauna stone.
