Description

Technical Field

[0001] This utility model belongs to the field of sprayer technology and relates to a spray head. Background Technology

[0002] Sprayers typically use a hand-cranked or small electric pump to draw liquid and spray it out through a nozzle for precise spraying. There are usually two types of nozzles for existing sprayers: cylindrical nozzles, also called cone nozzles, and fan nozzles. Both cylindrical and fan nozzles are single-mode water output nozzles. When different usage needs are required, people need to change the nozzle to switch the water output mode, which is inconvenient to use. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a new type of nozzle. The technical problem this invention aims to solve is how to enable a single nozzle to have multiple water output modes.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A spray nozzle includes a housing having an inlet end and an outlet end, characterized in that the housing is radially adjacent to each other with a first water distribution channel and a second water distribution channel respectively communicating with the inlet end and the outlet end; the housing has an outlet cover at the outlet end, the outlet cover having a spray water hole communicating with the first water distribution channel and a shower water hole communicating with the second water distribution channel; the housing has a cylindrical mounting base radially disposed thereon, a columnar valve core movably inserted into the mounting base; the inner wall of the mounting base has a first step portion, and the inlet of the second water distribution channel has a second step portion; the valve core can abut against the first step portion and the second step portion respectively to close the inlets of both the first water distribution channel and the second water distribution channel.

[0006] In use, simply connect this nozzle to the spray bar of the sprayer. Then, the user only needs to move the valve core inserted into the mounting base. The mounting base acts as a guide, allowing the valve core to abut against the first or second step. The design of the first and second steps makes the movement of the valve core more precise. The structure is simple and the operation is easy and convenient. This allows the valve core to better close the inlets of the first and second water distribution channels respectively, that is, to open the second water distribution channel connected to the shower head hole and the first water distribution channel connected to the spray hole respectively, thereby realizing the shower head liquid output mode or the spray liquid output mode, thus enabling a single nozzle to have multiple water output modes.

[0007] In one of the above-mentioned nozzles, the end of the mounting base furthest from the housing is provided with two L-shaped positioning blocks that press against the housing. The housing has two pressing blocks, which press against the two positioning blocks one by one. By rotating the mounting base, the two positioning blocks can be simultaneously disengaged from their corresponding pressing blocks. During installation, the mounting base is simply inserted radially into the mounting position on the side wall of the housing. Then, the mounting base is rotated so that the two L-shaped positioning blocks are positioned below the pressing blocks. When disassembly is required, the operation is reversed. This structure allows the mounting base to be detachably installed inside the housing, and it is easy to assemble and disassemble, facilitating the inspection and replacement of the internal structure of the housing.

[0008] In one of the above-mentioned nozzles, the housing has a cylindrical first partition plate. The outlet of the first water distribution channel is located inside the first partition plate, and the outlet of the second water distribution channel is located outside the first partition plate. The water outlet cover has a cylindrical second partition plate, which is sleeved on the outside of the first partition plate. The spray nozzle is located inside the second partition plate, and the shower nozzle is located outside the second partition plate. The cylindrical space formed by the first partition plate can be used to install atomizing nozzles. The outlet of the first water distribution channel is located inside the first partition plate, which allows for better communication with the atomizing nozzle installed inside the first partition plate. At the same time, the first and second partition plates are interlocked to prevent liquid inside the first partition plate from flowing to the outside of the second partition plate.

[0009] In one type of nozzle described above, the outer wall of the mounting base is provided with several first sealing rings that can seal against the inner wall of the housing. These first sealing rings are respectively located on both sides of the first water distribution channel. The side wall of the mounting base has several water passage holes. The mounting base has a cylindrical guide portion. The valve core is fitted with a second sealing ring and a third sealing ring that abuts against the guide portion. The second sealing rings can form a sealing abutment with both the inner wall of the housing and the inner wall of the mounting base. By providing the first sealing rings, liquid inside the housing can be prevented from leaking out from the connection between the mounting base and the housing. Because the first sealing rings seal the connection between the mounting base and the housing, liquid inside the housing can only communicate with the first water distribution channel through the water passages inside the mounting base. The guide portion provides better guidance and limiting for the movement of the valve core. The third sealing rings prevent liquid inside the housing from leaking out from the gap between the valve core and the mounting base. The second sealing rings allow the valve core to better seal the inlets of both the first and second water distribution channels.

[0010] In one of the above-mentioned nozzles, the valve core is provided with an annular groove, and the second sealing ring is disposed within the annular groove. The two side walls of the annular groove can respectively abut against the first step and the second step. The mating structure between the two side walls of the annular groove and the first and second steps allows for more precise movement of the valve core, avoiding situations where the valve core does not move into position. At the same time, the annular groove can also be used to house the second sealing ring, and the groove wall of the annular groove can limit the second sealing ring, allowing the valve core to better seal the inlets of both the first and second water distribution channels.

[0011] In one of the above-mentioned nozzles, the housing has an annular stepped portion, the water outlet cover is threaded onto the housing and abuts against the annular stepped portion, and a fourth sealing ring is provided between the water outlet cover and the housing. This makes the installation and removal of the water outlet cover more convenient. When the water outlet cover is rotated into place, it abuts against the annular stepped portion, which is very convenient. The fourth sealing ring can increase the sealing performance at the connection between the water outlet cover and the housing.

[0012] In one of the above-mentioned nozzles, a rotating shaft is arranged radially on the outer wall of the housing, and a swing button is provided on the rotating shaft. The end of the valve core extending out of the housing is connected to the swing button, and by pressing both ends of the swing button in sequence, the valve core can be moved to a position that closes the inlets of both the first and second water distribution channels. By providing a swing button, the operation of the user is made more convenient.

[0013] In one of the above-mentioned nozzles, the spray nozzles are located in the center of the water outlet cover, and the shower nozzles are arranged around the outside of the spray nozzles. The reasonable distribution of the spray nozzles and shower nozzles makes the spray more uniform.

[0014] Compared with existing technologies, the advantages of this spray head are as follows: This spray head only requires adjusting the position of the valve core to open the first water distribution channel connected to the spray nozzle and the second water distribution channel connected to the shower nozzle, respectively. Simultaneously, the design of the first and second steps allows for more precise movement of the valve core. The structure is simple, and operation is easy and convenient, thus enabling either a spray or shower nozzle mode, allowing a single spray head to have multiple water output modes. Furthermore, by setting an L-shaped positioning block on the mounting base and a corresponding pressing block on the housing, rotating the mounting base allows both positioning blocks to simultaneously disengage from their corresponding pressing blocks, making assembly and disassembly convenient.
