[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0031] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0032] like Figures 1-6 As shown, this utility model provides an adjustable nozzle, including: a nozzle body 100, which includes a nozzle base 1 and a nozzle cover 2. The nozzle base 1 has a first channel 101, a second channel 102 communicating with the first channel 101, a third channel 103 communicating with the second channel 102, and a fourth channel 104 communicating with the first channel 101. The nozzle cover 2 is rotatably mounted on the nozzle base 1. Therefore, when the nozzle body 100 is connected to an external pipe during use, the high-pressure liquid flow in the external pipe enters the fourth channel 104. In section 04, the nozzle enters the first channel 101 through the fourth channel 104, then the second channel 102, and finally the third channel 103 through the second channel 102. Since the nozzle cover 2 has a first nozzle cap 21 and a second nozzle cap 22 corresponding to the third channel 103, and the nozzle cover 2 is also rotatably connected to the nozzle seat 1, by rotating the nozzle cover 2, when the first nozzle cap 21 corresponds to the third channel 103, a first-shaped spray can be sprayed outward; when the second nozzle cap 22 corresponds to the third channel 103, a second-shaped spray can be sprayed outward.

[0033] The above design makes the nozzle body 100 easy to adjust. It can be used not only for ordinary liquid spraying, but also for disinfectant spraying, and can also be used on vacuum cleaner equipment. By rotating and adjusting different nozzles, different environments can be sprayed. It can be easily installed and the spray mode can be changed, making it highly versatile.

[0034] It is understood that those skilled in the art can also provide a third nozzle cap, a fourth nozzle cap, or even more nozzle caps on the nozzle cover 2 to meet the spraying needs of more scenarios, and this utility model will not list them all.

[0035] Exemplary nozzle holder

[0036] like Figures 1-6 As shown, further, some embodiments of this utility model provide a specific structure of the above-mentioned nozzle holder 1. Here, the nozzle holder 1 of this structure includes a seat plate 11, a seat body 12, and a tail rod 13. The seat plate 11 is installed at the front of the seat body 12, and the tail rod 13 is installed at the rear of the seat body 12. Of course, the above three can be integrally formed by injection molding. The first channel 101 and the third channel 103 are respectively inserted into the seat plate 11 and the seat body 12. The second channel 102 is opened in the seat body 12 and located between the first channel 101 and the third channel 103. The fourth channel 104 is inserted into the tail rod 13.

[0037] Due to the manufacturing process, the opening of the second channel 102 extends to the bottom of the seat 12. Therefore, the bottom of the seat 12 has a sealing body 121 to block the second channel 102, and the sealing body 121 prevents high pressure liquid leakage.

[0038] The nozzle cover 2 is rotatably connected to the base plate 11 via a fixed shaft 20, and the fixed shaft 20 extends to block the first channel 101. That is, the nozzle cover 2 rotates around the fixed shaft 20, and the fixed shaft 20 can be installed into the first channel 101 by various connection methods such as ultrasonic welding, glue connection, and threaded connection.

[0039] Furthermore, a protruding decorative seat 200 can be configured on the front wall of the nozzle cover 2, and the protruding decorative seat 200 has a first mounting hole 200a, a second mounting hole 200b, and a third mounting hole 200c corresponding to the first nozzle cap 21, the second nozzle cap 22, and the fixed shaft 20.

[0040] Exemplary first nozzle cap

[0041] like Figure 7 As shown, further, in some embodiments of the present invention, the first nozzle cap 21 has a first spray chamber 211 corresponding to the third channel 103, and the cap end of the first nozzle cap 21 has a strip-shaped spray outlet 212 communicating with the first spray chamber 211. Therefore, when the nozzle cover 2 is rotated so that the first nozzle cap 21 corresponds to the third channel 103, the high-pressure liquid inside enters the first spray chamber 211, and then sprays outward through the strip-shaped spray outlet 212 to present a strip-shaped first-shaped spray.

[0042] Exemplary second nozzle cap

[0043] like Figures 8-11 As shown, in some embodiments of this invention, the second nozzle cap 22 has a second spray chamber 221 corresponding to the third channel 103, and the cap end of the second nozzle cap 22 has a circular spray outlet 222 communicating with the second spray chamber 221. Therefore, when the nozzle cover 2 is rotated so that the second nozzle cap 22 corresponds to the third channel 103, the high-pressure liquid inside enters the second spray chamber 221, and is then sprayed outward through the circular spray outlet 222, presenting a cone-shaped second-shape spray. Here, the diameter of the circular spray outlet 222 is smaller than the inner diameter of the second spray chamber 221.

[0044] Furthermore, in order to ensure that the second nozzle cap 22 sprays a mist, an inner atomizing column 23 is provided inside the second spray chamber 221. An atomizing guide groove (not shown) is provided between the inner atomizing column 23 and the second spray chamber 221. The side wall of the inner atomizing column 23 has multiple first atomizing notches 231. An inner atomizing groove 232 is provided at the front end of the inner atomizing column 23. Several second atomizing notches 233 (two or more are suitable) are provided at the opening of the inner atomizing groove 232. The inner atomizing groove 232 is connected to the first atomizing notches 231 through the second atomizing notches 233 and the atomizing guide groove. Therefore, the high-pressure liquid in the third channel 103 enters the atomization guide groove through multiple first atomization notches 231, and then enters the inner atomization groove 232 through the second atomization notches 233. There can be two second atomization notches 233, so that two high-pressure liquids can be generated. The two high-pressure liquids enter the inner atomization groove 232 and generate a rotational centrifugal force, which is sprayed outward through the circular nozzle 222, thereby generating a second-shaped spray in a cone shape.

[0045] Exemplary card sales organization

[0046] like Figure 4 As shown, in some embodiments of this utility model, a locking mechanism 14 is further included. The locking mechanism 14 is installed in the locking hole 110 on the front wall of the base plate 11, and a first positioning hole 201 and a second positioning hole 202 corresponding to the locking mechanism 14 are provided on the rear wall of the nozzle cover 2. When the first nozzle cap 21 is aligned with the third channel 103, the locking mechanism 14 is aligned with the first positioning hole 201. When the nozzle cover 2 is rotated so that the second nozzle cap 22 is aligned with the third channel 103, the locking mechanism 14 is aligned with the second positioning hole 202. The locking mechanism 14 provides a pushing effect on the nozzle cover 2 to prevent the nozzle cover 2 from rotating during use and affecting the spraying effect.

[0047] Furthermore, the aforementioned locking mechanism 14 includes an inner spring 141 and an inner locking ball 142. The inner spring 141 is installed in the locking hole 105 of the nozzle seat 1 and abuts against the inner locking ball 142, causing the inner locking ball 142 to abut against the first positioning hole 201 and the second positioning hole 202, respectively. Therefore, when the nozzle cover 2 is rotated, the first positioning hole 201 disengages from the inner locking ball 142, and then the second positioning hole 202 rotates to correspond with the inner locking ball 142. A crisp sound can also be heard from the inner locking ball 142 to confirm whether the rotation is in place.

[0048] Furthermore, in some embodiments of this utility model, an inner sealing ring 106 is also installed on the outer end of the third channel 103. The inner sealing ring 106 prevents high-pressure liquid leakage when the first nozzle cap 21 and the second nozzle cap 22 are aligned with the third channel 103.

[0049] Furthermore, in some embodiments of this utility model, a first balance groove 111 and a second balance groove 112 are provided on the front wall of the seat plate 11. The first balance groove 111 and the second balance groove 112 are respectively located on both sides of the third channel 103, and the angle between the three is 120 degrees. A first balance ring 113 is installed in the first balance groove 111, and a second balance ring 114 is installed in the second balance groove 112. In this way, the design of the balance groove and the balance ring serves to balance the seat plate 11, prevent the edge from warping, and the first balance ring 113 and the second balance ring 114 contact the inner wall of the nozzle cover 2, which also serves to seal the surface.
