[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0035] Reference Figures 1 to 11 The embodiment of the present invention provides a disinfectant spray head with adjustable spraying angle, comprising a main shell 1 having a tubular spraying section 101, a pipe joint 2, a nozzle 3 and a screw cover 4 rotatable relative to the main shell 1 are arranged at the port of the spraying section 101, the pipe joint 2 is fixed relative to the main shell 1 and has a water inlet end 21 and a water outlet end 22, the nozzle 3 is cup-shaped and is sleeved on the water outlet end 22 of the pipe joint 2, a spray hole 31 is arranged on the bottom surface of the nozzle 3, a water guide groove 23 is arranged on the end surface of the water outlet end 22 of the pipe joint 2, the middle part of the water guide groove 23 is opposite to the spray hole 31, a confluence channel is arranged on the pipe joint 2, which can make the disinfectant introduced from the water inlet end 21 flow from each end of the water guide groove 23 to the middle part of the water guide groove 23, and the screw cover 4 is connected to the nozzle 3 through a transmission structure so that when the screw cover 4 is rotated, the nozzle 3 can be driven to move axially relative to the pipe joint 2.

[0036] like Figure 5 , Fig.10 , Fig.11 As shown, the water guide groove 23 can be straight, X-shaped or Y-shaped, wherein the straight water guide groove 23 has two ends, the X-shaped water guide groove 23 has four ends, and the Y-shaped water guide groove 23 has three ends.

[0037] Taking the straight water guide groove 23 as an example, when the nozzle 3 moves axially relative to the pipe joint 2, the distance between the end face of the water outlet end 22 of the pipe joint 2 and the inner bottom face of the nozzle 3 can be adjusted. When this distance increases, the disinfectant flows from the two ends of the water guide groove 23 to the injection hole 31. The angle between the flow path and the axis of the injection hole 31 will become smaller, making the sprayed disinfectant more concentrated and the injection angle smaller; when the distance between the end face of the water outlet end 22 of the pipe joint 2 and the inner bottom face of the nozzle 3 decreases, the disinfectant flows from the end of the water guide groove 23 to the injection hole 31. The angle between the flow path and the axis of the injection hole 31 will become larger, making the sprayed disinfectant more dispersed and the injection angle larger.

[0038] In a preferred embodiment of the present invention, the inner wall of the nozzle 3 is provided with an internal thread, the outer wall of the pipe joint 2 is provided with an external thread corresponding thereto, the two are threadedly connected, the screw cap 4 is provided with a nozzle mounting hole 41, the nozzle 3 is slidably arranged in the nozzle mounting hole 41, and the transmission structure includes a first axial slide groove 42 arranged on the inner wall of the nozzle mounting hole 41, and a guide block 32 arranged on the outer wall of the nozzle 3 and slidably matched with the first axial slide groove 42. In this embodiment, when the screw cap 4 is rotated, the nozzle 3 can be spirally rotated around the thread on the pipe joint 2, thereby adjusting the distance between the end face of the water outlet end 22 of the pipe joint 2 and the inner bottom face of the nozzle 3.

[0039] In order to improve the sealing performance, a rotating sealing ring is provided between the inner wall of the nozzle 3 and the pipe joint 2 , and a rotating sealing ring is also provided between the inner wall of the nozzle mounting hole 41 and the nozzle 3 .

[0040] In certain embodiments of the present invention, the transmission structure between the screw cap 4 and the nozzle 3 may also adopt the following structural form. For example, the principle of rotating the nut to drive the screw rod to move axially is adopted, and a mutually matching threaded structure is set between the screw cap 4 and the nozzle 3. At the same time, the inner hole of the nozzle 3 is set as a light hole, so that the nozzle 3 can move axially relative to the pipe joint 2.

[0041] In a preferred embodiment of the present invention, the confluence channel includes an axial blind hole 201 with the end face of the water inlet end 21 as the starting end, a plurality of transverse grooves 202 provided at the water outlet end 22 and connected to the end of the water guide groove 23, and a plurality of vertical holes 203 connecting each transverse groove 202 with the axial blind hole 201. When the disinfectant spray head of the present invention is applied to a disinfectant manufacturing machine or a disinfectant sprayer, the water inlet end 21 of the pipe joint 2 is connected to the water inlet pipe, and the flow path of the disinfectant is: water inlet pipe → axial blind hole 201 → vertical hole 203 → transverse groove 202 → water guide groove 23 → injection hole 31, and finally sprayed outward.

[0042] The above-mentioned confluence channel may also adopt other structural forms, as long as the structure can meet the following functions, that is, it can disperse the water flow of the water inlet pipe into several streams and allow each stream to enter the water channel 23 from the end of the water channel 23 respectively.

[0043] Reference Figure 5 As a further improvement of the present invention, there is an arc-shaped spoiler groove section 231 between the middle part of the water guide groove 23 and the end of the water guide groove 23. The function of the arc-shaped spoiler groove section 231 is to make the water flow spiral, so as to make the sprayed water column thinner.
