Description

Technical Field

[0001] This invention relates to the field of spray equipment technology, and more specifically, to a spray head. Background Technology

[0002] A showerhead is a device that disperses fluid into fine particles and accelerates its ejection, finding wide application in many fields. Among these, showerheads are widely used in public and residential bathrooms as cleaning tools for showering, washing, and massage. Specifically, to meet different usage needs, showerheads can be divided into those with filters and those without. Filter-equipped showerheads purify water, providing a cleaner water experience, while those without filters deliver a more powerful water flow. In daily use, it's necessary to have two different sizes of showerheads to switch between with and without filters, resulting in higher operating costs. Summary of the Invention

[0003] The purpose of this invention is to provide a nozzle that solves the problem of high operating costs associated with using nozzles with two different specifications in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] This invention provides a nozzle, comprising: a main body having a receiving cavity, the two ends of which are a water inlet and a first water outlet; a valve assembly disposed within the receiving cavity, the valve assembly including a valve seat, an elastic element, and a valve core, the valve seat having a water flow channel communicating with the water inlet and the first water outlet, the elastic element providing elastic force to drive the valve core to close the water flow channel; a filter assembly having a second water outlet and a water outlet at its two ends, the filter assembly having a first abutment post; and a faceplate assembly including a faceplate and a first abutment post connected to each other.

[0008] In some embodiments of this application, the water flow channel includes a first channel and a second channel that are connected to each other, and the width of the second channel is smaller than the width of the first channel; the first channel is connected to the water inlet end, and the second channel is connected to the first water outlet end; the elastic element provides elastic force to drive the valve core to close the second channel.

[0009] In some embodiments of this application, the valve seat has a guide hole; the valve core includes a rod and a head; the rod is movably inserted into the guide hole; and the head is used to close or open the water flow channel.

[0010] In some embodiments of this application, the valve seat includes a body and a guide seat; the water flow channel is formed within the body; the guide hole is disposed on the guide seat; the guide seat is provided with a water passage hole; the guide seat is connected to the body, and the water passage hole communicates with the water inlet end and the water flow channel; the elastic member is sleeved outside the rod portion, and both ends of the elastic member are respectively connected to the guide seat and the head.

[0011] Some embodiments of this application also include a pressure regulating valve; the pressure regulating valve is disposed in the receiving cavity; a pressure regulating cavity is formed between the pressure regulating valve and the inner wall of the receiving cavity, and the pressure regulating cavity is connected to the water inlet and the water flow channel.

[0012] In some embodiments of this application, the pressure regulating valve has an air hole; the main body has a vent hole that penetrates the inner wall and outer wall of the main body; the air hole is connected to the vent hole.

[0013] In some embodiments of this application, the main body includes a housing and a mounting cylinder; the housing has a fixed cavity; the mounting cylinder is disposed within the fixed cavity, and a locking structure is formed between the inner wall of the fixed cavity and the outer wall of the mounting cylinder; the locking structure includes a locking block and a limiting groove; the limiting groove includes a clearance groove and a locking slot; the locking slot is located inside the clearance groove, and the width of the locking slot is greater than the width of the clearance groove, and the first end of the locking slot communicates with the clearance groove; the locking block can enter the first end of the locking slot through the clearance groove; the locking block can move within the locking slot to allow the mounting cylinder to rotate relative to the housing, and when the locking block moves to the first end of the locking slot, the locking block is unlocked from the locking slot, and when the locking block moves to the second end of the locking slot, the locking block is locked into the locking slot; the mounting cylinder has a mounting cavity; the pressure regulating valve is disposed within the mounting cavity; the water inlet end and the first water outlet end are respectively formed at both ends of the fixed cavity.

[0014] In some embodiments of this application, the main body includes a housing and a mounting cylinder; the housing has a fixed cavity, and the inner wall of the fixed cavity has a first thread; the outer wall of the mounting cylinder has a second thread; the mounting cylinder is disposed in the fixed cavity, and the first thread is screwed to the second thread; the mounting cylinder has a mounting cavity; the pressure stabilizing valve is disposed in the mounting cavity; the water inlet and the first water outlet are respectively formed at both ends of the fixed cavity.

[0015] As can be seen from the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects: In the nozzle of this invention, when a filter element is required, the second water inlet is connected to the first water inlet, the faceplate is connected to the outlet, and the first abutment post contacts the valve core, causing the valve core to overcome the elastic force of the elastic element and open the water flow channel, thus forming the nozzle in a first state. Water flows into the receiving cavity from the inlet, and the water flow into the receiving cavity can pass through the water flow channel and through the filter assembly. The filter assembly filters the water, and the water filtered by the filter assembly is sprayed out from the outlet hole of the faceplate, which is suitable for usage scenarios that require a cleaner water flow.

[0016] When the filter cartridge is not in use, the faceplate is connected to the first water inlet, and the second abutment post contacts the valve core, causing the valve core to overcome the elastic force of the elastic element and open the water flow channel, thus setting the nozzle to its second state. Water flows into the receiving cavity from the inlet, and the water flow into the receiving cavity can pass through the water flow channel and spray out from the water outlet of the faceplate, which is suitable for use scenarios that require a strong water flow.

[0017] Since the second water inlet and the first water inlet, the faceplate and the water outlet, and the faceplate and the first water inlet are all detachably connected, the nozzle can be switched between the first and second states to adapt to different usage needs, without the need to equip two different sizes of nozzles, making it more flexible to use and saving costs.

[0018] In addition, when the nozzle switches between the first and second states, during the process of removing the filter assembly or cover from the main body, the first and second abutment posts gradually move away from the valve core and eventually lose contact with the valve core. The valve core loses the force of the first or second abutment post and closes the water flow channel under the drive of elastic force. The water remaining in the receiving cavity or water flow channel will not continue to flow out, improving the user experience. Attached Figure Description

Detailed Implementation

[0039] Although the invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the invention and is not intended to limit the invention to what is described herein.

[0040] Therefore, a feature pointed out in this specification is used to illustrate one feature of one embodiment of the invention, and does not imply that every embodiment of the invention must have the described feature. Furthermore, it should be noted that this specification describes many features. While certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0041] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of the invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0042] Please see Figures 1 to 7An embodiment of the present invention provides a nozzle that mainly includes a body 1, a valve assembly 2, a filter assembly 3, and a faceplate assembly 4. The body 1 has a receiving cavity, with an inlet end 111 and a first water passage end 112 at its two ends. The valve assembly 2 is disposed within the receiving cavity and includes a valve seat 21, an elastic element 22, and a valve core 23. The valve seat 21 has a water flow channel 213 connecting the inlet end 111 and the first water passage end 112. The elastic element 22 provides elastic force to drive the valve core 23 to close the water flow channel 213. The filter assembly 3 has a second water passage end 311 and an outlet end 312 at its two ends, and a first abutment post 321. The faceplate assembly 4 includes a faceplate 41 and a second abutment post 42 connected to each other, with the faceplate 41 having multiple water outlet holes. The nozzle has a first state and a second state. In the first state, the second water inlet 311 is detachably connected to the first water inlet 112, the cover 41 is detachably connected to the outlet 312, and the first abutment post 321 contacts the valve core 23, causing the valve core 23 to overcome the elastic force of the elastic member 22 and open the water flow channel 213. In the second state, the cover 41 is detachably connected to the first water inlet 112, the second abutment post 42 contacts the valve core 23, and the valve core 23 causes the valve core 23 to overcome the elastic force of the elastic member 22 and open the water flow channel 213.

[0043] In the nozzle of this embodiment of the invention, when the filter element 32 is required, the second water inlet 311 is connected to the first water inlet 112, the cover 41 is connected to the outlet 312, and the first abutment post 321 contacts the valve core 23, causing the valve core 23 to overcome the elastic force of the elastic member 22 and open the water flow channel 213, so that the nozzle forms a first state. Water flows into the receiving cavity from the inlet 111, and the water flow into the receiving cavity can pass through the water flow channel 213 and pass through the filter assembly 3. The filter assembly 3 filters the water, and the water filtered by the filter assembly 3 is sprayed out from the outlet hole of the cover 41, which is suitable for use scenarios that require cleaner water flow.

[0044] When the filter element 32 is not needed, the faceplate 41 is connected to the first water inlet 112, and the second abutment post 42 contacts the valve core 23, causing the valve core 23 to overcome the elastic force of the elastic element 22 and open the water flow channel 213, thus setting the nozzle to its second state. Water flows into the receiving cavity from the inlet 111, and the water flowing into the receiving cavity can pass through the water flow channel 213 and be sprayed out from the water outlet of the faceplate 41, which is suitable for use scenarios that require a strong water flow.

[0045] Since the second water inlet 311 and the first water inlet 112, the face cover 41 and the water outlet 312, and the face cover 41 and the first water inlet 112 are all detachably connected structures, the nozzle can be switched between the first state and the second state to adapt to different usage needs, without the need to equip two different specifications of nozzles, which is more flexible in use and saves costs.

[0046] Furthermore, when the nozzle switches between the first and second states, during the process of removing the filter assembly 3 or the cover 41 from the main body 1, the first abutment post 321 and the second abutment post 42 gradually move away from the valve core 23 and eventually lose contact with the valve core 23. The valve core 23 loses the force of the first abutment post 321 or the second abutment post 42 and closes the water flow channel 213 under the drive of elastic force. The water remaining in the receiving cavity or water flow channel will not continue to flow out, improving the user experience.

[0047] It should be noted that, Figure 3 yes Figure 1 A cross-sectional view in the first embodiment. Figure 4 yes Figure 1 A cross-sectional view in the second embodiment. See also... Figure 3 and Figure 4 The difference between the first and second embodiments lies in the structural composition of the main body 1, while there is no significant difference in the connection structure where the faceplate 41 is connected to the first water inlet 112 and the second abutment post 42 contacts the valve core 23. When the nozzle is in the first state, the second water inlet 311 is connected to the first water inlet 112, and the first abutment post 321 contacts the valve core 23. The connection structure in the second embodiment is also not significantly different from that in the first embodiment. Therefore... Figure 2 The cross-sectional view in the second embodiment is not specifically shown here; please refer to [reference needed]. Figure 5 , Figure 5 yes Figure 2 A cross-sectional view in the first embodiment.

[0048] Please see Figures 8 to 12 The first water inlet 112 is provided with a first locking part 1121, the second water inlet 311 is provided with a second locking part 3111, the water outlet 312 is provided with a third locking part 3121, and the face cover 41 is provided with a fourth locking part 411. When the second water inlet 311 rotates relative to the first water inlet 112, the second locking part 3111 can rotate to lock or unlock from the first locking part 1121. When the face cover 41 rotates relative to the water outlet 312, the fourth locking part 411 can rotate to lock or unlock from the third locking part 3121. In the first state, the second locking part 3111 rotates to lock to the first locking part 1121, and the fourth locking part 411 rotates to lock to the third locking part 3121. When the face cover 41 rotates relative to the first water inlet 112, the fourth locking part 411 can rotate to lock or unlock from the first locking part 1121. In the second state, the fourth locking part 411 rotates to lock onto the first locking part 1121. The connection between the main body 1 and the filter assembly 3, the filter assembly 3 and the face cover 41, and the main body 1 and the face cover 41 can be adjusted by rotation. The operation is relatively simple, quick, and easy to implement.

[0049] Both the first locking part 1121 and the second locking part 3111 are block-shaped. The second locking part 3111 is located between the first locking part 1121 and the water inlet end 111, and the first locking part 1121 is located between the second locking part 3111 and the water outlet end 312. When the second locking part 3111 rotates to align with the first locking part 1121, the second locking part 3111 locks itself to the first locking part 1121. When the second locking part 3111 rotates to a position where it is misaligned with the first locking part 1121, the second locking part 3111 unlocks itself from the first locking part 1121. When the second locking part 3111 rotates to align with the first locking part 1121, the first locking part 1121 prevents the second locking part 3111 from disengaging. When the second locking part 3111 rotates to a misalignment with the first locking part 1121, the first locking part 1121 does not obstruct the second locking part 3111. At this time, pulling the filter assembly 3 can separate the filter assembly 3 from the main body 1. Since both the second locking part 3111 and the first locking part 1121 are block-shaped, they can be quickly switched between alignment and misalignment by rotating a certain angle, making the operation convenient and easy. In other embodiments, both the second locking part 3111 and the first locking part 1121 are threaded, and the second water inlet end 311 and the first water inlet end 112 are fixed by threaded connection. Specifically, the second water inlet end 311 needs to rotate a certain number of turns relative to the first water inlet end 112 in order to achieve the fixation and separation between the first water inlet end 112 and the second water inlet end 311.

[0050] It should be noted that the shapes and mating relationships of the third locking part 3121 and the fourth locking part 411, as well as the first locking part 1121 and the fourth locking part 411, are set with reference to the first locking part 1121 and the second locking part 3111 in the above embodiment, and will not be described in detail here.

[0051] In this embodiment, there are multiple first locking parts 1121, second locking parts 3111, third locking parts 3121 and fourth locking parts 411, and the multiple locking parts are spaced apart along the circumferential direction.

[0052] In this embodiment, in the first state, the first water inlet 112 is fitted onto the second water inlet 311, and the water outlet 312 is fitted onto the cover 41. In the second state, the first water inlet 112 is fitted onto the cover 41. It is conceivable that in other embodiments, in the first state, the second water inlet 311 is fitted onto the first water inlet 112, and the cover 41 is fitted onto the water outlet 312. In the second state, the cover 41 is fitted onto the first water inlet 112. This fitted design increases the contact area at the connection point, enhancing the stability of the connection. Furthermore, water needs to pass through a more complex flow path to seep out from the gap between the two, making it less prone to leakage and thus resulting in better sealing performance.

[0053] In this embodiment, the nozzle further includes a first fastener and a second fastener. A first fastening hole is provided on the first water inlet end 112. A second fastening hole is provided on the water outlet end 312. In a first state, the first fastener is locked in the first fastening hole, and one end of the first fastener abuts against the outer wall of the second water inlet end 311. The second fastener is locked in the second fastening hole, and one end of the second fastener abuts against the outer wall of the faceplate 41. In a second state, the first fastener is locked in the first fastening hole, and one end of the first fastener abuts against the outer wall of the faceplate 41.

[0054] Please see Figures 1 to 7 The water flow channel 213 includes a first channel 2131 and a second channel 2132 that are connected, with the width of the second channel 2132 being smaller than the width of the first channel 2131. The first channel 2131 is connected to the water inlet 111, and the second channel 2132 is connected to the first water outlet 112. The elastic element 22 provides elastic force to drive the valve core 23 to close the second channel 2132. By setting the first channel 2131 and the second channel 2132 with different widths, and using the elastic element 22 to drive the valve core 23 to close the narrower second channel 2132, the water flow is controlled, ensuring effective water sealing when water spraying is not required.

[0055] In this embodiment, the elastic element 22 provides elastic force to drive the valve core 23 into the second channel 2132. The peripheral side of the valve core 23 contacts the inner wall of the second channel 2132 to close the second channel 2132. By contacting the peripheral side of the valve core 23 with the inner wall of the second channel 2132, the part of the valve core 23 in contact with the second channel 2132 achieves the blockage of water flow, preventing water from continuing to pass through, thereby achieving direct and effective blocking in the direction of water flow.

[0056] Please see Figures 3 to 7 as well as Figure 13 In a further embodiment, the valve core 23 includes a head 232 and a sealing ring 233. The sealing ring 233 is fitted onto the peripheral side of the head 232. The elastic member 22 provides elastic force to drive the head 232 into the second channel 2132, and the sealing ring 233 is sandwiched between the peripheral side of the head 232 and the inner wall of the second channel 2132 to close the second channel 2132. Because the sealing ring 233 has elastic force, after being squeezed into the second channel 2132, it rebounds and can tightly fit the inner wall of the second channel 2132 and the peripheral side of the head 232, thereby enhancing the sealing performance between the valve core 23 and the second channel 2132 and improving the water sealing effect.

[0057] In this embodiment, a limiting part is provided in the second channel 2132. The elastic member 22 provides elastic force to drive the valve core 23 to abut against the limiting part. The design of the limiting part restricts the movement range of the valve core 23 in the second channel 2132, ensuring that the valve core 23 can accurately and stably close the second channel 2132, and ensuring that the nozzle structure can reliably achieve automatic water sealing.

[0058] In this embodiment, a transition surface is provided between the first channel 2131 and the second channel 2132, and the transition surface is a conical inclined surface. The flared end of the transition surface connects to the first channel 2131, and the constricted end connects to the second channel 2132. The transition surface serves two purposes: firstly, it guides the water flow, optimizing the flow path and reducing water flow resistance; secondly, it positions and guides the valve core 23 during its movement, ensuring that the valve core 23 can smoothly transition from the first channel 2131 to the second channel 2132, thus guaranteeing the smooth operation of the automatic water sealing process.

[0059] Please see Figures 3 to 7 as well as Figure 14 The valve seat 21 has a guide hole 2121. The valve core 23 includes a rod 231 and a head 232. The rod 231 is movably inserted into the guide hole 2121. The head 232 is used to close or open the water flow channel 213. When the valve core 23 moves, the rod 231 can move axially along the guide hole 2121, thereby guiding the valve core 23 and ensuring the accuracy and stability of the main body 1 in closing and opening the water flow channel 213.

[0060] The valve seat 21 includes a body 211 and a guide seat 212. A water flow channel 213 is formed within the body 1. A guide hole 2121 is provided on the guide seat 212. The guide seat 212 is provided with a water passage hole 2122. The guide seat 212 is connected to the body 1, and the water passage hole 2122 connects the inlet end 111 and the water flow channel 213. An elastic member 22 is sleeved on the outside of the rod portion 231, and both ends of the elastic member 22 are respectively connected to the guide seat 212 and the head 232. The body 1 is used to ensure the formation of the water flow channel 213 within the valve seat 21, the guide seat 212 is used to ensure that the valve seat 21 can guide the movement of the valve core 23, and the water passage hole 2122 allows the water entering from the inlet end 111 to normally enter the water flow channel 213, thereby ensuring the stability of the nozzle structure. The elastic element 22 is sleeved on the outside of the rod 231 to ensure that the elastic element 22 can act on the valve core 23 in the correct direction. The two ends of the elastic element 22 are respectively connected to the guide seat 212 and the head 232, ensuring that the valve core 23 can act stably on the head 232, so that the head 232 can close or open the water flow channel 213.

[0061] Please see Figures 3 to 5 as well as Figure 15The nozzle also includes a pressure regulating valve 5. The pressure regulating valve 5 is located within the receiving cavity. A pressure regulating chamber is formed between the pressure regulating valve 5 and the inner wall of the receiving cavity, and this chamber connects to the water inlet 111 and the water flow channel 213. The design of the pressure regulating valve 5 ensures that the nozzle maintains stable operating performance under various water pressure environments. Simultaneously, it reduces nozzle damage caused by water pressure fluctuations and extends the nozzle's service life.

[0062] The pressure regulating valve 5 has an air vent 51. The main body 1 has a vent 113 penetrating both the inner and outer walls of the main body 1. The air vent 51 is connected to the vent 113. When the pressure regulating valve 5 operates, the internal air pressure changes. The design of the air vent 51 and the vent 113 ensures that the pressure regulating valve 5 is connected to atmospheric pressure, preventing pressure changes inside the valve from affecting its function of stabilizing water pressure.

[0063] Please see Figures 15 to 18 In the first embodiment, the main body 1 includes a housing 11 and a mounting cylinder 12. The housing 11 has a fixed cavity, and the inner wall of the fixed cavity has a first thread 115. The outer wall of the mounting cylinder 12 has a second thread 122. The mounting cylinder 12 is located within the fixed cavity, and the first thread 115 is screwed onto the second thread 122. The mounting cylinder 12 has a mounting cavity. A pressure regulating valve 5 is located within the mounting cavity. A water inlet end 111 and a first water outlet end 112 are formed at opposite ends of the fixed cavity. The mounting cylinder 12 and the housing 11 are connected by threads, providing a stable connection and allowing for quick disassembly. Furthermore, when the pressure regulating valve 5 needs to be removed for replacement, the connection between the first thread 115 and the second thread 122 is first released, the mounting cylinder 12 is removed from the fixed cavity, and then the pressure regulating valve 5 is removed from the mounting cavity, making the operation quick and convenient.

[0064] In this embodiment, the housing 11 includes a first housing 116 and a second housing 117. One end of the first housing 116 is a first connecting end, and one end of the second housing 117 is a second connecting end. The other end of the first housing 116 forms a water inlet end 111, and the other end of the second housing 117 forms a first water outlet end 112. The first connecting end is screwed to the second connecting end, and a fixing cavity is provided inside the second housing 117. It is conceivable that both the second housing 117 and the mounting cylinder 12 are provided with vent holes.

[0065] Please see Figure 19 and Figure 20In the second embodiment, the main body 1 includes a housing 11 and a mounting cylinder 12. The housing 11 has a fixing cavity. The mounting cylinder 12 is disposed within the fixing cavity, and a locking structure is formed between the inner wall of the fixing cavity and the outer wall of the mounting cylinder 12. The locking structure includes a locking block 114 and a limiting groove 121. The limiting groove 121 includes a clearance groove 1211 and a locking slot 1212. The locking slot 1212 is located inside the clearance groove 1211, and the width of the locking slot 1212 is greater than the width of the clearance groove 1211. The first end of the locking slot 1212 communicates with the clearance groove 1211. The locking block 114 can enter the first end of the locking slot 1212 through the clearance groove 1211. The locking block 114 is movable within the locking groove 1212 to allow the mounting cylinder 12 to rotate relative to the housing 11. When the locking block 114 moves to the first end of the locking groove 1212, the locking block 114 is unlocked from the locking groove 1212. When the locking block 114 moves to the second end of the locking groove 1212, the locking block 114 is locked into the locking groove 1212. The mounting cylinder 12 has a mounting cavity. The pressure regulating valve 5 is located in the mounting cavity. The water inlet end 111 and the first water outlet end 112 are respectively formed at both ends of the fixed cavity.

[0066] The cooperation of the locking block 114 and the locking groove 1212 enables a stable connection and quick disassembly between the mounting cylinder 12 and the housing 11. Furthermore, when the pressure regulating valve 5 needs to be removed for replacement, the locking block 114 is unlocked into the locking groove 1212 and withdrawn along the clearance groove 1211. The mounting cylinder 12 is then removed from the fixed cavity, and the pressure regulating valve 5 is removed from the mounting cavity. This operation is relatively quick and convenient. It should be noted that in this embodiment, the mounting cylinder 12 is provided with a vent hole, and there is an assembly gap between the housing 11 and the mounting cylinder 12. The vent hole is connected to atmospheric pressure through this assembly gap.

[0067] In this embodiment, the main body 1 also includes a fixing member 13. The housing 11 is provided with a fixing hole, the fixing member 13 is locked in the fixing hole, and one end of the fixing member 13 abuts against the outer wall of the mounting cylinder 12. The fixing member 13 can prevent the connection between the mounting cylinder 12 and the main body 1 from becoming loose, which would cause the locking block 114 to rotate and unlock in the locking slot 1212, making the connection between the mounting cylinder 12 and the main body 1 more stable.

[0068] In this embodiment, the filter assembly 3 includes a cylinder 31 and a filter element 32. The cylinder 31 is provided with a filter chamber, and a second water inlet 311 and a water outlet 312 are formed at both ends of the filter chamber. The filter element 32 is disposed in the filter chamber, and a first abutment post 321 is disposed on the filter element 32.
