Specific embodiments

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] For a further understanding of the content of the present invention, the present invention will be described in detail with reference to the accompanying drawings.

[0023] Combined with Figure 1 and Figure 2 , a fire direct current spray water gun, comprising a main pipe body 1, a connecting pipe 4 fixedly connected to one side of the main pipe body 1, a joint 41 fixedly connected to the inner wall of the connecting pipe 4, an inner buffer assembly 3 for buffering water flow arranged inside the main pipe body 1, and an outer buffer assembly 5 for facilitating clamping of a water pipe and buffering during use arranged outside the connecting pipe 4.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Combined with Figures 2 - 5, the inner buffer component 3 includes a fixed cylinder 31 fixedly connected to the inner wall of the main pipe body 1. A contraction groove 32 is formed on one side of the fixed cylinder 31. A spring 33 is fixedly connected to the inner wall of the contraction groove 32. One end of the spring 33 is fixedly connected to a buffer cylinder 35. A groove is provided on one side of the buffer cylinder 35, and the groove corresponds to the fixed cylinder 31. An inclined inner groove 352 is provided on the inner wall of the buffer cylinder 35. A connecting short plate 354 is fixedly connected to one side of the buffer cylinder 35. One end of the connecting short plate 354 is fixedly connected to a limiting ring 355. A sliding groove 353 is formed on the inner wall of the fixed cylinder 31, and an inner groove is formed on the surface of the sliding groove 353. The connecting short plate 354 and the limiting ring 355 are respectively slidably connected to the sliding groove 353 and the inner groove formed on the surface of the sliding groove 353. Through the settings of the fixed cylinder 31, the contraction groove 32, the spring 33, the buffer cylinder 35, the inclined inner groove 352, the sliding groove 353, the connecting short plate 354 and the limiting ring 355, when water flows in, the water flows along the buffer cylinder 35 and flows to the other side along the inclined inner groove 352. The inclined inner groove 352 serves the purpose of buffering and increasing the water flow velocity. At the same time, under the impact of the water flow, the spring 33 is compressed, so that the buffer cylinder 35 fits with the fixed cylinder 31. The connecting short plate 354 and the limiting ring 355 are slidably connected to the sliding groove 353 and the inner groove formed on the surface of the sliding groove 353. The inner groove limits the limiting ring 355 to ensure the stability of the sliding, so as to quickly buffer the rapidly incoming water flow, protect the internal components, and reduce the reaction force on the user.

[0026] A water-proof membrane 34 is fixedly connected between the buffer cylinder 35 and the fixed cylinder 31. Through the setting of the water-proof membrane 34, the contraction groove 32 is sealed to prevent water from entering the inner wall of the contraction groove 32 and affecting the use of the spring 33.

[0027] A sealing ring 351 is fixedly connected to the outer side of the buffer cylinder 35. The sealing ring 351 fits with the inner wall of the main pipe body 1. Through the setting of the sealing ring 351, the contraction groove 32 is further sealed, and at the same time, it is ensured that all the water flows between the buffer cylinders 35.

[0028] A filter screen 12 is fixedly connected to the inner wall of the main pipe body 1, and a pressurizing water pump 13 is also fixedly connected to the inner wall of the main pipe body 1. Through the settings of the filter screen 12 and the pressurizing water pump 13, the effects of filtering impurities to prevent blockage and pressurizing the water flow are achieved.

[0029] The outer buffer assembly 5 includes a fixing ring 51 fixedly connected to the outside of the connecting pipe 4. There are two fixing rings 51 in total, and the two groups of fixing rings 51 are arranged correspondingly. A sleeve 52 is fixedly connected between the two groups of fixing rings 51. An inner sleeve 54 is fixedly connected to the outside of the sleeve 52, and an outer buffer sleeve 55 is fixedly connected to the outside of the inner sleeve 54. Nitrogen is filled inside the outer buffer sleeve 55. A side groove 53 is opened on the outside of the sleeve 52, and a notch corresponding to the side groove 53 is opened on the outside of the connecting pipe 4. The inner sleeve 54 is connected to the inside of the connecting pipe 4 through the side groove 53. Through the settings of the fixing ring 51, the sleeve 52, the side groove 53, the inner sleeve 54 and the outer buffer sleeve 55, when using the water gun, the outer buffer sleeve 55 can be clamped by the arm, and the nitrogen inside the outer buffer sleeve 55 plays a buffering effect. The concave setting of the sleeve 52 can make it more convenient for the arm and the body to fit the water gun, reducing the harm caused to the body by the recoil force generated by the excessive water flow. At the same time, when the water is flowing, a small amount of water enters the inside of the inner sleeve 54 through the side groove 53. Therefore, during the buffering process, the inner sleeve 54 uses the water layer for buffering, enhancing the buffering effect.

[0030] A nozzle assembly 2 for switching the spraying form is arranged on one side of the main pipe body 1. The nozzle assembly 2 includes an atomizing nozzle head 21 and a jet nozzle head 22 rotatably connected to the outside of the main pipe body 1. A handle 11 is slidably connected to the outside of the main pipe body 1. Through the settings of the handle 11, the atomizing nozzle head 21 and the jet nozzle head 22, the purpose of facilitating the switching of the spraying form of the water gun is achieved.

[0031] A handle 6 is fixedly connected to the outside of the main pipe body 1. A buffer pad 63 is fixedly connected to one side of the handle 6. Anti-slip patterns 62 are arranged on the outside of the handle 6. A finger groove 61 is opened on one side of the handle 6. Through the settings of the handle 6, the finger groove 61, the anti-slip patterns 62 and the buffer pad 63, the purpose of facilitating the gripping of the handle 6 to control the main pipe body 1 is achieved. The buffer pad 63 and the anti-slip patterns 62 cooperate to achieve the effects of buffering and anti-slip.

[0032] Specifically, when using the water gun, the water flow enters the inside of the main pipe body 1 and first impacts the buffer cylinder 35. The buffer cylinder 35 slowly fits with the fixed cylinder 31 under the buffering action of the spring 33. At the same time, the water flow converges towards the middle along the sealing ring 351, increasing the water flow velocity. The sliding groove 353 plays a limiting effect on the connecting short board 354 and the limiting ring 355, ensuring the stability of the movement of the buffer cylinder 35, thereby buffering the initial large water flow impact. At the same time, the user clamps the outer buffer sleeve 55 with the arm, and uses the outer buffer sleeve 55 to buffer the contact part. After the water gun is opened, water enters the inside of the inner sleeve 54, further enhancing the buffering effect. Finally, the purpose of buffering and protecting people when the water gun is opened is achieved.
