Description

TECHNICAL FIELD

[0001] The technical scheme relates to the technical field of spray heads, in particular to a rotary spray head. BACKGROUND

[0002] A spray head is a device usually installed at the outlet of a pipe or container, designed to control the flow, direction, and form of fluids such as water, gas, or chemical solutions, widely used in shower systems, agricultural irrigation, fire fighting systems, cleaning equipment, and industrial spraying.

[0003] The existing spray head is applied to different use scenarios. When different water outlet effects (spraying, spraying, and width spraying) are needed, the user needs to close the water source, disassemble the old nozzle, clean the interface, install the new nozzle, and a series of cumbersome steps to replace the nozzle effect. Not only is it time-consuming, but it may also cause water leakage or affect work efficiency due to improper operation, making it inconvenient to use and in need of improvement. SUMMARY

[0004] The technical scheme is provided to improve the problem that the frequent disassembly and replacement of the spray head to change the water outlet effect cause inconvenience in use, and provides a rotary spray head.

[0005] The purpose of the technical scheme is achieved as follows:

[0006] A rotary spray head includes a spray head barrel and a spray head body. The spray head body is rotationally connected to the output end of the spray head barrel. A first channel is formed in the spray head barrel and communicates with the spray head body. At least two second channels are formed in the spray head body. A blocking part is provided on the output end of the spray head barrel. The end face of the blocking part is located on one side of the connection position between the spray head barrel and the spray head body.

[0007] When the spray head body is installed on the output end of the spray head barrel, the blocking part blocks part of the second channels, so that the first channel only communicates with one of the second channels.

[0008] Through the above technical scheme, when the rotary spray head is in normal use, the rotary spray head realizes manual switching of the water outlet mode through the rotary linkage structure of the spray head barrel and the spray head body. When the user rotates the spray head body, the multiple independent second channels (such as columnar direct shooting, atomizing spraying, and scattering shower modes) provided inside are sequentially and accurately aligned with the first channel of the spray head barrel. At this time, the blocking part automatically blocks the entrance of the second channel that is not selected by cooperating with the rotation track, and only the target channel is kept in communication with the water supply system. Compared with the traditional disassembly and replacement type spray head, the present scheme can realize instantaneous conversion of the water outlet form through the rotation angle, and the water flow remains continuous during the switching process without interrupting the water supply. This improves the smoothness of user experience and makes the use more convenient and reliable.

[0009] Preferably, the nozzle body comprises:

[0010] The lower housing is rotatably sleeved on the outside of the output end of the nozzle holder;

[0011] The upper housing connects to the lower housing and, together with the lower housing, forms a receiving cavity;

[0012] The nozzle core is installed in the receiving cavity. The second channel is opened in the nozzle core and extends through the upper and lower end faces. The lower end face of the nozzle core abuts against the blockage part.

[0013] The nozzle core can follow the lower housing, thereby enabling the connection between different second channels and the first channel.

[0014] Through the above technical solution, the lower housing is rotatably sleeved on the outside of the nozzle holder output end to achieve a rotatable fit with the holder; the upper housing is fixedly connected to the lower housing to form a closed receiving cavity for installing the nozzle inner core; the nozzle inner core is embedded in the receiving cavity, and its lower end face forms a dynamic sealing contact with the blocking part of the nozzle holder through axial pressure. At the same time, multiple independent second channels (such as flow channels corresponding to different spray modes) are opened inside the nozzle inner core. Each second channel runs through its upper and lower end faces. When it is necessary to switch the spray mode, the user rotates the lower housing, which drives the nozzle inner core to rotate synchronously, so that one of the second channels of the nozzle inner core is axially aligned and connected with the first channel (main water supply channel) fixed in the nozzle holder, while the remaining second channels are blocked by the blocking part, which also facilitates maintenance and replacement.

[0015] Preferably, the nozzle core includes:

[0016] The core seat has a limiting part protruding along the outer side wall, and the inner wall of the upper housing is correspondingly formed with a limiting groove, which is used for the limiting part to be inserted to achieve axial synchronous rotation.

[0017] The core column assembly includes a plurality of core columns, each core column being provided with a second channel. Each second channel includes an inlet hole for input and an outlet hole for output. The upper housing is provided with a flow passage hole corresponding to the position of the outlet hole.

[0018] Through the above technical solution, the core seat's limiting part is aligned with the limiting groove for embedded engagement design, ensuring that the nozzle core is accurately positioned when the nozzle body rotates. The inlet holes of each second channel in the core column are dynamically aligned with the first channel of the nozzle cylinder seat as the rotation moves, while the outlet holes output water flow in a directional manner through the flow holes of the upper shell.

[0019] Preferably, the core column assembly includes at least three core columns, which are a mist spray column, a direct spray column, and a wide-width spray column;

[0020] The outlet hole of the wide spray column is formed with a conical corner groove, which is widened in the direction away from the outlet hole. The flow passage hole is provided with flow channel grooves on the inner walls on both sides, and the flow channel grooves are connected to the corner groove.

[0021] The upper housing has an inner part with a mounting portion and a corresponding mounting groove. The mist spray column has a protruding barrier ring portion. The upper end of the mist spray column is embedded in the mounting groove, and the barrier ring portion abuts against the mounting portion for sealing.

[0022] The mist spray column has a flow guide block, which is provided with a hollow groove and several flow guide parts. There is a flow guide hole between two adjacent flow guide parts. The flow guide hole guides the water flow output from the outlet hole into the hollow groove. The hollow groove is connected to the flow passage hole.

[0023] Through the above technical solution, the multi-core column differentiated structure achieves precise control of the water outlet pattern. The core column assembly includes three core columns, such as mist spray column, direct spray column and wide spray column, which are integrated into the core base. When rotating and switching, the corresponding mode is selected by aligning the second channel and the first channel of the core column. The conical corner groove of the wide spray column and the flow channel groove on both sides of the flow hole form a wide-mouth guiding space, so that the water flow diffuses through the corner groove and then extends twice through the flow channel groove to form a wide fan surface.

[0024] The blocking ring of the spray column is pressed tightly and sealed with the mounting groove, allowing the solution output from the outlet to enter the mounting groove. The water flow from the outlet is divided into multiple fine streams through the guide hole. After collision with the guide part, the water flows in a spiral direction and mixes turbulently in the empty groove. Finally, it is atomized and sprayed out through the flow hole. This design, through the differentiation of the core column's functional structure, allows the three modes of direct injection, atomization, and wide-width to operate independently without interference. The geometric features of the flared angle groove and the guide hole directly shape the water flow dynamics. During rotation switching, the sealing surface is pressed together and the flow channel shape is adapted simultaneously. This not only ensures the sealing reliability of mode switching, but also achieves stepless switching of diversified water output effects through structural integration.

[0025] Preferably, an installation structure is provided between the upper housing and the lower housing, the installation structure including a guide groove portion disposed on the upper housing and a guide block portion disposed on the lower housing;

[0026] The guide block portion includes a guide block 1 protruding from the inner wall of the lower housing, and the guide groove portion includes a straight groove section 1 and a slot section 1. The straight groove section 1 is connected to the side wall of the slot section 1, and the slot section 1 is provided with an anti-dislodgement spring piece.

[0027] During the installation of the upper and lower housings, the guide block is embedded along the straight groove section. After the upper and lower housings rotate relative to each other axially, the guide block is translated into the slot section. The anti-detachment spring is located on the rear side of the guide block along the moving direction, forming a resisting and limiting action on the guide block.

[0028] Through the above technical solution, the guide groove of the upper shell includes a straight groove section and a slot section with an anti-detachment spring. After the guide block of the lower shell is axially embedded along the straight groove section, the guide block is slid into the slot section by rotating the upper shell or the lower shell. At this time, the anti-detachment spring elastically presses against the rear side of the guide block, forming a one-way limit. This structure simplifies the assembly process to two steps: "axial alignment - rotation locking". The translational trajectory of the guide block in the slot section and the elastic force of the anti-detachment spring not only avoid accidental loosening caused by reverse rotation, but also ensure that the upper and lower shells fit tightly through mechanical limit. After optimization, a stable connection between the shells can be achieved without additional fasteners. At the same time, the rotation locking mechanism and the anti-detachment design work together to improve assembly efficiency.

[0029] Preferably, the guide block portion includes a second guide block protruding from the inner wall of the lower housing, and the guide groove portion further includes a second straight groove section and a second slot section, wherein the second straight groove section is correspondingly connected to the side wall of the second slot section;

[0030] During the installation of the upper and lower housings, the guide block 2 is embedded along the straight groove section 2. After the upper and lower housings rotate relative to each other axially, the guide block 2 is moved into the slot section 2.

[0031] Through the above technical solution, during the assembly of guide block one along straight groove section one and slot section one, similarly, after guide block two of the lower housing is axially embedded along straight groove section two, guide block two is slid into slot section two by rotating the upper housing or the lower housing, which further improves the assembly stability and makes the housing connection have higher vibration resistance and structural stability.

[0032] Preferably, the inner wall of the slot section one near the straight groove section one has a guide surface one, and the inclination direction of the guide surface one causes the slot section one to be flared towards the straight groove section one.

[0033] The second slot section has a guide surface two on its inner wall near the second straight slot section. The inclination direction of the guide surface two causes the second slot section to be flared towards the second straight slot section.

[0034] Through the above technical solution, after the guide block two is axially embedded along the straight groove section two, during rotational assembly, the guide surface two of the slot section two contacts the side wall of the guide block two through the flared inclined surface. The radial component force generated by the inclined surface pushes the guide block two to smoothly transition along the arc trajectory of the guide surface two. At the same time, the flared structure changes the initial contact area between the guide block two and the guide surface two into a progressive guiding passage. Similarly, the guide surface one of the slot section one achieves self-centering compensation through the flared guidance when the guide block one enters, eliminating the offset during the rotation stage. The synergistic effect of the two guide surfaces optimizes the meshing operation between the guide block and the slot. After the straight groove section completes the axial pre-positioning, the flared guide surface guides the rotation path to correct the radial deviation, improving the reliability of repeated assembly.

[0035] Preferably, the guide block one has a guide surface three, which is adapted to the guide surface one, and the anti-detachment spring has a guide surface four adapted to the guide surface three.

[0036] Through the above technical solution, as the guide block moves along the slot section 1 through the anti-detachment spring, the guide surface 3 of the guide block 1 contacts and connects with the guide surface 4 of the anti-detachment spring. The inclined surface guides the guide block 1 to overcome the elastic force of the anti-detachment spring and pass through. The inclined angle of the guide surface 4 guides the spring to deform elastically under pressure, thereby improving stability.

[0037] Preferably, the lower housing has a first mounting port, a fixing groove is provided inside the lower housing, a second mounting port is provided at the bottom of the fixing groove, and a sealing plug protrudes from the nozzle holder;

[0038] The cross-sectional dimension of the sealing plug is smaller than the channel cross-section of the first mounting port, and the cross-sectional dimension of the sealing plug is larger than the channel cross-section of the second mounting port, so that after the nozzle holder passes through the first and second mounting ports, the sealing ring is embedded and internally supported on the inner wall of the fixing groove for positioning.

[0039] Through the above technical solution, during the assembly of the nozzle holder, one end of the nozzle holder passes through mounting port one and mounting port two, allowing the sealing plug to be embedded in the fixing groove after passing through mounting port one. Based on the limitation that its cross-sectional size is larger than that of mounting port two, the sealing ring is triggered to support the inner wall of the fixing groove, forming an interference fit internal support sealing structure, thereby improving assembly stability.

[0040] Preferably, the sealing plug has a positioning groove along its circumferential sidewall, and the fixing groove has a positioning protrusion along its inner wall that fits into the positioning groove.

[0041] Through the above technical solution, the positioning groove and the positioning protrusion are fitted one-to-one. During the rotation process, the positioning groove and the positioning protrusion interlock to achieve gear self-locking, which not only ensures a clear sense of segmentation when switching rotation, but also restricts the degree of freedom of circumferential rotation, avoids the nozzle body from rotating, and improves stability.

[0042] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0043] 1. This technical solution uses the rotating linkage structure between the nozzle base and the main body, combined with multiple independent second channels (columnar direct spray / atomized spray / scattering shower) and a blocking part to achieve multi-level rotational switching. During rotation, the blocking part automatically blocks non-target channels, ensuring that only the selected channel is connected to the first channel. The water flow is continuous and uninterrupted throughout the switching process, forming a replacement-free instantaneous switching mechanism, which improves the smoothness and reliability of operation.

[0044] 2. This technical solution achieves assembly through the connection structure between the upper and lower shells via the cooperation of the guide groove and the guide block. After the guide blocks one and two are axially embedded along the straight groove section one and two respectively, the shell is rotated to make the guide blocks slide into the corresponding side slot section. The anti-loosening spring elastically presses against the rear side of the guide block one to form a one-way limit. The synergistic effect of the two guide blocks simplifies the assembly into an "axial alignment-rotation locking" operation, realizing contact mechanical locking, effectively preventing loosening and improving structural stability.

[0053] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0054] Example:

[0055] See Figure 1 A rotating nozzle includes a nozzle holder 1 and a nozzle body 2. The nozzle body 2 is rotatably connected to the water outlet end of the nozzle holder 1. The two achieve relative movement through axial rotation. The other end of the nozzle holder 1 away from the connection point is used to receive water flow. Different water outlet modes are switched by rotating the nozzle body 2 to achieve multiple functions such as mist spraying, direct spraying, and wide-area spraying.

[0056] See Figure 2 and Figure 3 The nozzle body 2 includes a lower housing 21, an upper housing 22, and a nozzle core 23. The upper housing 22 is connected to the lower housing 21 and forms a receiving cavity 36. The nozzle core 23 is installed in the receiving cavity 36. The nozzle core 23 includes a core seat 231 and a core column assembly 232 disposed on the core seat 231. The core column assembly 232 includes a plurality of core columns. In this embodiment, the core column assembly 232 includes at least three core columns. The three core columns are a mist spray column 2321, a direct spray column 2322, and a wide spray column 2323.

[0057] The nozzle holder 1 has a first channel 3 that connects to the nozzle body 2. The nozzle body 2 has at least two second channels 4. In this embodiment, each core column has a second channel 4, resulting in three different second channels 4. Each second channel 4 includes an inlet hole 41 for input and an outlet hole 42 for output. The through-hole of each inlet is formed on the side of the core holder 231 away from the core column assembly 232. The upper housing 22 has three flow holes 8, which are arranged one by one to correspond to the positions of the outlet holes 42.

[0058] See Figure 2 and Figure 4 The core base 231 is provided with a limiting part 6. There are two limiting parts 6. The two limiting parts 6 protrude along the outer side wall of the core base 231 and are symmetrically distributed on opposite sides of the core base 231. The inner wall of the opening end of the upper housing 22 is correspondingly formed with two limiting grooves 7. The two limiting grooves 7 are fitted into the two limiting parts 6 one by one, so as to realize the synchronous rotation of the upper housing 22 and the nozzle inner core 23. At this time, the core column assembly 232 is located in the receiving cavity 36. The three core columns are aligned with the three flow holes 8. The ends of the direct spray column 2322 and the width spray column 2323 with the outlet hole 42 are respectively embedded in two of the flow holes 8.

[0059] Direct injection mode (JET): Water flows directly through the outlet hole 42 of the direct injection column 2322, forming a concentrated water flow.

[0060] In the width adjustment mode (FAN), a conical corner groove 10 is formed at the outlet hole 42 of the width spray column 2323. The corner groove 10 is flared outwards in the direction away from the outlet hole 42. Correspondingly, flow channel grooves 9 are provided on the inner walls of the flow holes 8 on both sides. The flow channel grooves 9 are connected to the corner groove 10 to form a fan-shaped water flow. The mist spray column 2321 abuts against the inner wall of another flow hole 8. The diameter of the flow hole 8 is smaller than that of the other two flow holes 8. Alternatively, two or more locking parts can be formed on the outer wall of the core seat 231, and two locking parts protrude from the inner wall of the upper shell 22, with the two locking parts corresponding to the two locking parts.

[0061] See Figure 4 and Figure 7 Mist spray mode (MIST): The upper housing 22 has an internally formed mounting portion 11, with a corresponding internally formed mounting groove 12. The bottom of the mounting groove 12 communicates with one of the flow holes 8. A blocking ring 13 protrudes from the mist spray column 2321. The cross-sectional dimension of the blocking ring 13 is larger than the cross-sectional dimension of the groove opening of the mounting groove 12, causing the upper part of the mist spray column 2321 to embed into the mounting groove 12. The blocking ring 13 abuts against its opening, thus sealing the side of the mounting groove 12 facing inwards from the upper housing 22. 2321 has a flow guide block 14, which is set at one end of the mist spray column 2321 embedded in the mounting groove 12 and abuts against the inner wall of the upper housing 22. The side of the flow guide block 14 away from the core seat 231 has a hollow groove 15 and several flow guide parts 16. There are three flow guide parts 16, and there is a flow guide hole 17 between two adjacent flow guide parts 16. After the water flow output from the outlet hole 42 fills the mounting groove 12, it flows along the extension direction of the flow guide hole 17, is dispersed into a mist water flow through the flow guide part 16, and is sprayed out from the flow hole 8 to form a mist spray.

[0062] See Figure 6 The nozzle body 2 is rotatably connected to the output end of the nozzle cylinder seat 1. Specifically, the rotatable connection is as follows: the lower housing 21 has a first mounting port 29 and a second mounting port 30. The cross-section of the first mounting port 29 is larger than that of the second mounting port 30. One end of the nozzle body 2 is provided with a sealing plug 31. The other end of the nozzle body 2 away from the sealing plug 31 enters the lower housing 21 through the first mounting port 29 and then extends out through the second mounting port 30. Since the cross-sectional size of the sealing plug 31 is smaller than that of the first mounting port 29 and larger than that of the second mounting port 30, it is restricted from passing through the second mounting port 30. The lower housing 21 also has a fixing groove 33, which is located inside the lower housing 21 near the second mounting port 30. The sealing plug 31 is precisely embedded in the fixing groove 33 and is positioned against the inner wall of the fixing groove 33 to achieve sealing. The sealing plug 31 can rotate freely in the fixing groove 33.

[0063] The fixing groove 33 has multiple positioning protrusions 34 along its inner peripheral wall, and the sealing plug 31 has multiple positioning grooves 35 along its outer peripheral side wall. The distribution of the positioning grooves 35 corresponds one-to-one with the position of the positioning protrusions 34, so that when the sealing plug 31 rotates relative to the lower housing 21, each positioning protrusion 34 can be interlocked into the adjacent positioning groove 35 along the rotation direction to achieve gear self-locking and multi-level positioning, which ensures a clear and segmented feel when switching rotation.

[0064] See Figure 5 An installation structure 18 is provided between the upper housing 22 and the lower housing 21. At least two sets of installation structures 18 are provided. Each installation structure 18 includes a guide groove 19 and a guide block 20 provided on the lower housing 21. The guide groove 19 is opened on the outer side wall of the upper housing 22 and includes a straight groove section 191, a slot section 192, a straight groove section 193, and a slot section 194. One end of the straight groove section 191 has an opening extending downward. The slot section 192 is arranged laterally along the outer wall of the upper housing 22. One end of the slot section 192 extends to the side wall of the straight groove section, and the other end extends to another straight groove section 193. The slot section 192 is provided with an anti-detachment spring piece 24. One end of the spring piece 24 is integrally formed on the upper housing 22, and the other end away from the straight groove section 191 can be pressed. The spring piece 24 has a guide surface 28, which is inclined downward toward the side of the straight groove section 191.

[0065] The second straight groove section 193 has another opening extending downwards parallel to the first straight groove section 191. One end of the second slot section 194 is connected to the side wall of the second straight groove section 193. The first slot section 192 has a guide surface 25 near the inner wall of the first straight groove section 191, and its inclination direction makes the first slot section 192 flared towards the first straight groove section 191. The second slot section 194 has a guide surface 26 near the inner wall of the second straight groove section 193, and its inclination direction makes the second slot section 194 flared towards the second straight groove section 193.

[0066] The guide block section 20 includes a guide block 1 201 and a guide block 202 protruding from the inner wall of the lower housing 21. The guide block 1 201 has a guide surface 3 27, the inclination direction of which is adapted to the guide surface 4 28. After the nozzle cylinder seat 1 and the nozzle inner core 23 are respectively installed with the lower housing 21 and the upper housing 22, the guide block 1 201 in each group is aligned with the opening end of the straight groove section 191, and at this time the guide block 202 is correspondingly aligned with the opening end of the straight groove section 293. The upper housing 22 and the lower housing 21 are aligned with the guide block 201. As the housing 21 approaches, guide block 201 is inserted along straight groove section 191, and guide block 202 is inserted along straight groove section 293. By rotating the upper housing 22 relative to the lower housing 21, guide block 201 slides into slot section 192 and presses down the anti-disengagement spring 24. The anti-disengagement spring 24 resets and abuts against the rear side of guide block 201 to prevent it from coming out, forming a resisting limit on guide block 201. At this time, guide block 202 slides into slot section 294 accordingly.

[0067] See Figure 2 and Figure 4 The nozzle holder 1 is also provided with a blocking part 5, which includes multiple parts. The blocking part 5 protrudes from the end face of the nozzle holder 1 near the nozzle body 2. When the upper housing 22 and the lower housing 21 are installed, the blocking part 5 abuts against the end face of the nozzle inner core 23 where the inlet hole 41 is provided. One end of one of the second channels 4 is aligned and connected with the first channel 3. The blocking part 5 blocks the inlet holes 41 of other non-corresponding second channels 4. After the nozzle body 2 and the nozzle holder 1 rotate relative to each other, the first channel 3 switches to flow with another adjacent inlet hole 41 along the rotation direction, realizing three-level switching.

[0068] The specific work process of this plan is as follows:

[0069] This technical solution achieves manual switching of water output modes through a rotating linkage structure between the nozzle holder 1 and the nozzle body 2. When the user rotates the nozzle body 2, multiple independent second channels 4 (such as columnar direct spray, atomized spray, wide fan-shaped spray, etc.) are precisely aligned with the first channel 3 of the nozzle holder 1. At this time, the blocking part 5 automatically blocks the inlet of the unselected second channel 4 in coordination with the rotation trajectory, leaving only the target channel connected to the water supply system. Compared with traditional replaceable nozzles, this solution can achieve instantaneous switching of water output mode by rotating the angle, and the water flow remains continuous during the switching process. There is no need to interrupt the water supply and frequently switch nozzles, which improves the smoothness of the user experience and makes it more convenient and reliable to use.
