[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] A multi-purpose fire extinguishing water gun with adjustable spray pattern, such as Figures 1 to 7 As shown, the main valve body 1 includes a main pipe 101. A handle 102 is fixedly connected to the bottom end of the main pipe 101. One end of the handle 102 is connected to a nozzle 103. A support rod 104 is fixedly connected to the inner wall of the nozzle 103. A baffle 105 is fixedly connected to the end of the support rod 104. A valve plate 106 is slidably connected to the inner wall of the main pipe 101. A pull rod 107 is fixedly connected to the side wall of the valve plate 106. A sliding frame 108 is fixedly connected to the end of the pull rod 107. A lever 109 is rotatably connected to the side wall of the main pipe 101. A push rod 110 is fixedly connected to one end of the lever 109 located inside the main pipe 101. The push rod 110 is slidably sleeved on the inner wall of the sliding frame 108.

[0031] By holding the handle 102 and pushing the lever 109, the lever 109 causes the push rod 110 to flip. The push rod 110 pushes the sliding frame 108, causing the sliding frame 108 to pull the lever 107. This causes the lever 107 to slide the valve plate 106, allowing water inside the main pipe 101 to flow into the nozzle 103. After releasing the lever 109, the water flow and water pressure push the valve plate 106 back to its original position, causing the valve plate 106 to fit against the inner wall of the main pipe 101, preventing water inside the main pipe 101 from flowing into the nozzle 103. By continuously pushing the lever 109, the valve plate 106 can never contact the main pipe 101, allowing the water gun to continuously spray water. Repeatedly pushing and releasing the lever 109 allows water inside the water gun to spray intermittently, thus achieving point spraying.

[0032] Please refer to this carefully. Figure 1 and Figure 4The connecting mechanism 2 is connected to the main pipeline 101 far from the nozzle 103, and comprises a connecting pipe 201, a stop ring 202 fixedly sleeved on the inner wall of the connecting pipe 201, two groups of protrusions 203 fixedly connected to the inner wall of the connecting pipe 201 and located beside the stop ring 202, a connector 205 sleeved on the inner wall of the connecting pipe 201, one end of the connector 205 abutting against the side wall of the stop ring 202, a water pipe 208 connected to the other end of the connector 205, a sliding block 206 slidingly sleeved on the inner wall of the connector 205, the end of the sliding block 206 abutting against the side wall of the protrusion 203, a groove 204 formed in the protrusion 203 at the position where the protrusion 203 contacts the sliding block 206, and a first reset spring 207 fixedly connected to one end of the sliding block 206 in the connector 205 and to the inner wall of the connector 205.

[0033] The connector 205 is inserted into the connecting pipe 201, so that the connector 205 abuts against the side wall of the stop ring 202, and then the connector 205 is rotated to drive the sliding block 206 to rotate, so that the sliding block 206 contacts the protrusion 203, the sliding block 206 is pushed to slide into the connector 205, and the first reset spring 207 is compressed, after the sliding block 206 is aligned with the groove 204, the first reset spring 207 rebounds to make the sliding block 206 abut against the groove 204, so that the water pipe 208 is connected to the main pipeline 101, when disassembling, the connector 205 is rotated in the reverse direction to push the sliding block 206 again, so that the sliding block 206 slides into the connector 205 again, and when the sliding block 206 no longer contacts the protrusion 203, the first reset spring 207 rebounds to push the sliding block 206 to reset, at this time, the connector 205 is pulled to separate the connector 205 from the connecting pipe 201.

[0034] Please refer to Figure 2 , Figure 3 and Figure 5 , the outer wall of the nozzle 103 is provided with an adjusting mechanism 3, the adjusting mechanism 3 comprises an adjusting sleeve 301, the adjusting sleeve 301 is rotatably sleeved on the outer wall of the nozzle 103, two groups of jacks 306 abutting against the inside of the adjusting sleeve 301, the adjusting sleeve 301 is provided with a positioning groove at the position where the adjusting sleeve 301 contacts the jacks 306, the jacks 306 are slidingly connected to the side wall of the nozzle 103, the end of the jack 306 is fixedly connected with a second reset spring 307, the outer wall of the adjusting sleeve 301 is sleeved with a sleeve pipe 303, the outer wall of the adjusting sleeve 301 is provided with an inclined groove 302, the inner wall of the sleeve pipe 303 is fixedly connected with a sliding column 305, the sliding column 305 is slidingly sleeved on the inner wall of the inclined groove 302, and the end of the sleeve pipe 303 is fixedly connected with a horn 304.

[0035] By rotating the adjusting sleeve 301, the adjusting sleeve 301 pushes the top 306, so that the top 306 slides towards the inside of the nozzle 103, and the second reset spring 307 is compressed when the top 306 is pushed, so that the adjusting sleeve 301 cannot rotate automatically when no one rotates the adjusting sleeve 301, the chute 302 is rotated during the rotation of the adjusting sleeve 301, the chute 302 pushes the sliding column 305 to make the sleeve 303 slide, the sleeve 303 pushes the gap between the bell mouth 304 and the baffle 105 to reduce during the sliding of the sleeve 303, so that the water flow is sprayed from the narrow gap, the sprayed water presents umbrella-shaped water mist, and reverse rotation of the adjusting sleeve 301 makes the sleeve 303 move reversely, so that the gap between the bell mouth 304 and the baffle 105 is increased, so that the sprayed water is gathered into a water column and sprayed forward.

[0036] In use, the push rod 110 pushes the sliding frame 108 by pushing the push rod 109, so as to push the valve plate 106 to make the water flow be sprayed out, when it is needed to carry out point shooting, the valve plate 106 is continuously opened and closed by continuously pushing the push rod 109, so that the water sprayed out of the water gun is intermittently sprayed out, the function of point shooting is realized, and the electric shock phenomenon in the fire extinguishing process is avoided, and the parts not involved in the device are the same as the prior art or can be realized by using the prior art.

[0037] Although the embodiments of the utility model have been shown and described, the specific embodiments are only the explanation of the utility model, and are not the limitation of the utility model, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable way, the person skilled in the art can make the modification, replacement and change of the embodiments without creative contribution after reading the specification without departing from the principles and purposes of the utility model, but as long as in the claim range of the utility model, it is protected by the patent law.
