## Background
FIELD OF THE INVENTION
The present invention relates to a mop, and particularly to a pressing spray mop.
BACKGROUND OF THE INVENTION
In current common or commercially available spray mops, water spray is primarily triggered by a lever, as disclosed in the U.S. Pat. Nos. 7,048,804, 9,173,540, 8,844,088 and 6,579,023. In the above technical solutions of triggering water spray by a lever, the lever primarily serving as a trigger source is disposed on a handle of the spray mop. Thus, manufacturers need to dispose a connecting line along a mop rod of the spray mop, and a pump structure on the spray mop is then activated by the connecting line to perform water spray. However, due to factors such as long-term use or unsatisfactory assembly, the connecting line may become malfunctioning such that the spray mop fails to perform spraying. Further, also because of the connecting line disposed, maintenance is made more inconvenient. In addition, to ensure that the connecting line is reliably triggered by the lever, the mop rod of the spray mop implemented by the above technical solution cannot be adjusted in length according to actual requirements, hence disfavoring its application.
In view of the above, some manufacturers have improved the technical structure of the foregoing spray mop to provide an application of water spray achieved by downwardly pressing a mop rod, e.g., as disclosed in the Taiwan Patent No. 586,407, and the China Patent Nos. 204207689, 204246077 and 203244350. Among the above, the China Patent No. 204246077 discloses a spray mop including a mop rod and a spray mechanism. The spray mechanism includes a water pump and a bottle seat. The water pump is installed in the water seat. The mop rod is vertically slidably connected to the water seat, and is connected to a piston of the water pump. When the spray mop enters a spray state, the mop rod is perpendicular to the ground, and the piston of the water pump is driven when the mop rod moves in the bottle seat to cause the water pump to spray water. Further, the China Patent No. 203244350 discloses an improved spray mop. The spray mop includes a pressing rod, a mop rod, a water storage bottle, a housing and a mop head. The mop rod is connected to a mop rod connector of the housing. The housing includes a pressure pump and a water storage bottle connector disposed in a fixed form. The pressure pump includes an entrance connected to a water entrance connector, and a piston rod connected to a water exit connector. The water storage bottle is fixedly connected to the water bottle connector, and is connected to the water entrance connector via a water entering pipe. The water exit connector is connected to a nozzle fixed on the housing via a water exiting pipe. The pressing rod is movably disposed on the mop rod connector and abuts upon the water exit connector. The pressing rod and the piston rod of the pressure pump are located on the same axial line.
In the above technical solution disclosing the spray mop that implements water spray by pressing the mop rod, associated elements that the spray mop adopts to implement water spray need to be assembled through external components such as screw elements or riveting elements. Thus, an installation process for involving these external components is increased to lead to an increase in labor hours. Further, during the assembly process involving the external components, an issue of poor assembly may occur, such that the components may become loose and connecting points of the components may even be damaged in more severe cases, hence disfavoring mass production or user applications.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Details and technical contents of the present invention are given with the accompanying drawings below.
Referring to FIG. 1 to FIG. 3, the present invention provides a pressing spray mop. The pressing spray mop includes a mop rod 1, a mop head 2 disposed at one end of the mop rod 1, a water tank seat 3 disposed on the mop rod 1, a spray mechanism 4 installed at the water tank seat 3, and a water tank 5 installed on the water tank seat 3 and storing a cleaning liquid. The spray mechanism 4 includes a water drawing member 41, a connecting tube assembly 42 connected to the water drawing member 41 and the water tank 5, and a spray member 43 connected to the water drawing member 41. The water tank seat 3 includes a hollow housing 31 and two support half casings 32. The hollow housing 31 includes a plurality of installation ribs 311 each abutting against at least one of the support half casings 32. The installation ribs 311 are arranged at an interval in the hollow housing 31. The position and the form of appearance of each of the installation ribs 311 arranged in the hollow housing 31 are adjusted according to the shape of the support half casings 32, so as to substantially limit or securely support each of the support half casings 32 in the hollow housing 31. Further, one of the two support half casings 32 includes at least one tenon 321 facing the other support half casing 32, and the other of the two support half casings 32 not provided with the tenon 321 includes at least one mortise 322 corresponding to each tenon 321. Thus, the two support half casings 32 can be joggled with each other using the tenon 321 and the mortise 322 without involving external components (e.g., screw fastening elements or riveting elements) for assembly. Further, each of the support half casings 32 includes an accommodating chamber 323 for accommodating the spray mechanism 4. The appearance of each of the accommodating chambers 323 corresponds to the shape of the spray mechanism 4 to securely accommodate the spray mechanism 4 therein. Further, each of the accommodating chambers 323 includes at least one first accommodating portion 324 for disposing the water drawing member 41, and a second accommodating portion 325 for disposing the connecting tube assembly 42. In one embodiment, the two accommodating chambers 323 may be symmetrical structures. In the installation process of the present invention, the spray mechanism 4 is placed in the accommodating chamber 323 of one of the support half casings 32, and the accommodating chamber 323 of the other support half casing 32 is correspondingly disposed with the spray mechanism 4. Thus, the two support half casings 32 are joggled and joined, and the spray mechanism 4 is encapsulated in the two support half casings 32, thereby completing the assembly of the two support half casings 32 and the spray mechanism 4. From this point, the spray mechanism 4 is supported by the two support half casings 32. Further, each of the support half casings 32 includes a recessed portion 326 connected to the accommodating chamber 323. The two recessed portions 326 form a movement space 33 when the two support half casings 32 are joggled. Further, the two recessed portions 326 are connected to the first accommodating portion 324 and are disposed correspondingly to the water drawing member 41 of the spray mechanism 4, and thus the movement space 33 formed also corresponds to the water drawing member 41. Further, the hollow housing 31 includes a spray opening 314 disposed correspondingly to a spray member 43 of the spray mechanism 4.
Referring to FIG. 1 to FIG. 5, the hollow housing 31 include a through connecting hole 312 disposed correspondingly to the movement space 33. The mop rod 1 includes a rod body 11 to be accommodated by the water tank seat 3, a penetration opening 12 disposed on the rod body 11, and a pressing pin 13 provided at the penetration opening 12 and extended into the movement space 33 via the through connecting hole 312. Further, when the water tank seat 3 is accommodated around the rod body 11 by the hollow housing 31, the penetration opening 12 corresponds to and is in communication with the through connecting hole 312. Next, the pressing pin 13 may sequentially insert into the penetration opening 12 and the through connecting hole 312 to enter the movement space 33. Thus, due to the effect of the pressing pin 13, the water tank seat 3 becomes inseparable from the mop rod 1. In addition, the pressing pin 13 simultaneously limits the movements of the hollow housing 31 and the two support half casings 32, thereby completing the assembly of the water tank seat 3 and the mop rod 1. Thus, without involving external components, the assembly of the water tank seat 3 and the mop rod 1 can be achieved without involving external components, hence omitting the assembly process that uses external components. Further, the stability of the assembled water tank seat 3 and mop rod 1 is substantial to the stability of an assembly achieved with external components. Again referring to FIG. 1 to FIG. 5, in the present invention, the pressing pin 13 is inserted into the rod body 11, and is driven by the rod body 11 as the rod body 11 moves. When the rod body 11 is pressed downwards towards the direction of the mop head 2 by a user operation, the pressing pin 13 linearly moves in the movement space 33 and presses the water drawing member 41 to cause the spray mechanism 4 to perform spraying. At the beginning of water spray performed by the spray mechanism 4, the spray mechanism 4 draws a cleaning liquid in the water tank 5, and sprays the cleaning liquid from the spray opening 314 via the spray member 43. When the user later stops the force that presses the mop rod 1 downwards, the a restoration spring disposed correspondingly to the water drawing member 41 in the spray mechanism 4 pushes the water drawing member 41 up to an original position. During the restoration process of the water drawing member 41, the water drawing member 41 simultaneously pushes up the pressing pin 13 to drive the mop rod 1 to restore an non-pressed form. In one embodiment, the rod body 11 of the mop rod 1 is further a hollow rod body 11, the pressing pin 13 includes at least one inverted hook 131. The inverted hook 131 protrudes from a surface of the pressing pin 13, and limits and prohibits the pressing pin 13 from disengaging from the mop rod 1 after the pressing pin 13 is installed at the rod body 11.
Again referring to FIG. 1 to FIG. 5, in one embodiment, the water tank seat 3 includes a sealing cover 34. The sealing cover 34 is installed in the hollow housing 31 to limit the two support half casings 32. More specifically, the sealing cover 34 is disposed at one side of the water tank seat 3 assembled with the water tank 5, and is then assembled with the hollow housing 31 to seal the two support half casings 32 after the hollow housing 31 and the two support half casings 32 are assembled. The sealing cover 34 includes at least one connecting piece 341 disposed at an edge and along an inner wall of the hollow housing 31. Each of the connecting pieces 341 includes a fastening stopping portion 342 protruding towards a direction of the hollow housing 31. The hollow housing 31 includes at least one limiting hole 313 that forms a fastening relationship with the fastening stopping portion 342. When the fastening stopping portion 342 falls in the limiting hole 313 during the assembly process of the sealing cover 34, the limiting hole 313 and the fastening stopping portion 342 produce a fastening relationship, such that the sealing cover 34 becomes inseparable from the hollow housing 31. Further, the sealing cover 34 includes a through hole 343 disposed correspondingly to the spray mechanism 4. The through hole 343 allows the water tank 5 to penetrate therein to be connected to the spray mechanism 4.
Referring to FIG. 6 and FIG. 7, in one embodiment, the pressing spray mop of the present invention includes a mobile connecting mechanism 6 connected to the mop rod 1 and the mop head 2. The mobile connecting mechanism 6 has a locked state and a utilization state. In the locked state, the mop rod 1 is placed levelly on the mop head 2 to prohibit the mop rod 1 from being pressed downwards. In the utilization state, the mop rod 1 is at an inclined angle relative to the mop head 2 to allow the mop rod 1 to be pressed downwards. In one embodiment, the inclined angle is 90 degrees. Further, in the present invention, in addition to the function of assembling the mop rod 1 and the mop head 2, the mobile connecting mechanism 6 further provides a function of limiting and prohibiting the pressing spray mop from performing water spray. The mobile connecting mechanism 6 includes a connecting seat 61 disposed on the mop head 2, a connecting member 62 disposed on the mop rod 1, and an inserting member 63. The connecting seat 61 includes a connecting pole 611, and a connecting sleeve 612 assembled on the connecting pole 611 and capable of rotating multi-directionally. The part of the connecting pole 611 installed in the connecting sleeve 612 includes a penetration hole 613 formed at the inclined angle. On the other hand, the connecting sleeve 612 includes two correspondingly disposed installation holes 614. The connecting member 62 includes a trigger head portion 621 facing the connecting pole 611 and a hollow portion 622. The appearance of the trigger head portion 621 is formed correspondingly to the form of the penetration hole 613 to allow the trigger head portion 621 to move in the penetration hole 613. The hollow portion 622 penetrates the connecting member 62 and may be a long hole. Further, in the installation process of the embodiment, the inserting member 63 passes through one of the installation holes 614 and the hollow portion 622 to be disposed on the other installation hole 614. In other words, the inserting member 63 of the present invention fixedly connects the two installation holes 614 and penetrates the hollow portion 622. As such, the connecting sleeve 612 is assembled with the connecting member 62. Further, with such design of the hollow portion 622, the inserting member 63 is allowed to linearly move in the hollow portion 622 according to the application of the mop rod 1. The connecting seat 61 further includes base 615 for disposing the connecting pole 611, and the base 615 is further disposed on the mop head 2. Referring to FIG. 5 and FIG. 7, when the mop rod 1 is operated by the user and has an inclined angle relative to the mop head 2, the mobile connecting mechanism 6 is in the utilization state. When the mop rod 1 is pressed downwards by a force received, the inserting member 63 is capable of linearly moving in the hollow portion 622. Thus, the trigger head portion 621 of the connecting member 62 is allowed to extend into the penetration hole 613 to allow the mop rod 1 to be pressed downwards to perform spraying. On the other hand, when the mop rod 1 is operated by the user and placed levelly on the mop head 2, the mobile connecting mechanism 6 is in the locked state, and the trigger head potion 621 of the connecting member 62 is abutted against the connecting pole 611 to prohibit the mop rod 1 from being pressed downwards.
