DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3, the present utility model discloses an anti - mis - pressing structure for a spray screw - cap head, which includes a screw - cap body 2. A self - locking pressing structure 3 is fixedly installed at the top end of the screw - cap body 2. A nozzle 4 is arranged on the outer side of the screw - cap body 2, and a straw 5 is arranged on the inner side of the screw - cap body 2. The self - locking pressing structure 3, the nozzle 4 and the straw 5 are interconnected.

[0022] The self - locking pressing structure 3 includes a top cover 301. An activity rod 302 is slidably connected inside the top cover 301. A pressing head 303 is fixedly installed at the top end of the activity rod 302. Two first slots 304 and two second slots 305 are opened at the top end of the top cover 301;

[0023] A socket plate 308 is movably sleeved on the surface of the activity rod 302. Two follower rods 309 are fixedly installed at the bottom end of the socket plate 308.

[0024] By setting the self - locking pressing structure 3, the connecting shaft can drive the follower rod 309 to rotate on the surface of the activity rod 302 through the adjusting plate, so that the follower rod 309 can be switched between the first slot 304 and the second slot 305, thereby limiting the activity rod 302. When mis - touched, it can provide a blocking support for the activity rod 302 so that it will not move downward, thus realizing the anti - mis - touch function, that is, preventing the internal material from being extruded and avoiding unnecessary waste.

[0025] Specifically, a screw - cap ring 1 is arranged at the bottom end of the screw - cap body 2. Spiral ridges are arranged on the inner side of the screw - cap ring 1.

[0026] In this embodiment, the screw - cap ring 1 can be used to complete the threaded connection between the screw - cap body 2 and the liquid storage bottle, thereby facilitating the disassembly and assembly between the screw - cap body 2 and the liquid storage bottle.

[0027] Specifically, the two first slots 304 and the two second slots 305 are staggered and opened at the top end of the top cover 301, and the depth of the second slot 305 is greater than the depth of the second slot 305.

[0028] In this embodiment, since the depth of the first slot 304 is lower than the depth of the second slot 305, the follower rod 309 inserted into the first slot 304 cannot move along the direction of the first slot 304, so that the activity rod 302 cannot be pressed, thus completing the anti - mis - touch function.

[0029] Specifically, the two follower rods 309 are arranged in a diagonal direction, and the specifications of the follower rods 309 are adapted to the sizes of the openings of the first slot 304 and the second slot 305.

[0030] In this implementation scheme, by using the follower rod 309 arranged diagonally, each rotation of the follower rod 309 can only insert into two first slots 304 or two second slots 305, so that the movable range of the movable rod 302 can be accurately controlled.

[0031] Specifically, a chute 306 is formed on the surface of the movable rod 302, and a connecting bearing 307 is slidably connected inside the chute 306. The surface of the connecting bearing 307 is movably sleeved with the inner cavity of the socket plate 308.

[0032] In this implementation scheme, the connecting bearing 307 is pulled in advance, so that the connecting bearing 307 is lifted along the inside of the chute 306, and the connecting bearing 307 drives the follower rod 309 to be lifted synchronously through the socket plate 308, so that the follower rod 309 is moved out of the second slot 305, thus facilitating the staff to switch the movable range of the movable rod 302.

[0033] When in use, when it is necessary to extract materials, only need to press down the pressing head 303, so as to prompt the pressing head 303 to drive the movable rod 302 to descend, and the movable rod 302 drives the socket plate 308 to drive the follower rod 309 to displace inside the second slot 305 through the connecting bearing 307, so that the movable rod 302 can reach the maximum displacement value at this time, and the movable rod 302 can suck out the materials through the straw 5 and spray them out through the nozzle 4;

[0034] And the linkage relationship among the nozzle 4, the straw 5 and the self-locking pressing structure 3 belongs to the common nozzle structure in the prior art. Therefore, the linkage working principle among the nozzle 4, the straw 5 and the self-locking pressing structure 3 is well-known, and they all belong to conventional means or common general knowledge, so it will not be elaborated here;

[0035] When it is necessary to limit the movable rod 302, the connecting bearing 307 is pulled in advance, so that the connecting bearing 307 is lifted along the inside of the chute 306, and the connecting bearing 307 drives the follower rod 309 to be lifted synchronously through the socket plate 308, so that the follower rod 309 is moved out of the second slot 305. Then the socket plate 308 is rotated, so that the socket plate 308 drives the follower rod 309 to gradually rotate above the first slot 304. Then the connecting bearing 307 is released, and the connecting bearing 307 automatically falls due to the gravity factor, so that the connecting bearing 307 drives the follower rod 309 to automatically insert into the first slot 304 through the socket plate 308;

[0036] Since the depth of the first slot 304 is lower than the depth of the second slot 305, the movable rod 302 cannot drive the follower rod 309 to move along the direction of the first slot 304 at this time, so that the movable rod 302 cannot be pressed at this time, thus completing the anti-misoperation function.

[0037] In summary, for the anti-misoperation pressing structure of the spray screw cap head, by setting the self-locking pressing structure 3, the connecting shaft can drive the follower rod 309 to rotate on the surface of the movable rod 302 through the adjusting plate, so that the follower rod 309 can be switched between the first slot 304 and the second slot 305, thereby limiting the movable rod 302. When mis-touched, it can provide a blocking support for the movable rod 302 to prevent it from moving downward, thus realizing the anti-misoperation function, that is, preventing the internal material from being extruded and avoiding unnecessary waste.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
