[0032] Please see Figures 1 to 4 To address the problems of traditional spray guns having limited functionality, low cleaning efficiency, and poor cleaning effect, this utility model provides a spray gun 100 with a brush head. The spray gun 100 includes a spray gun body 10 and a cleaning brush head 20, which is connected to the spray gun body 10. The cleaning brush head 20 includes a nozzle assembly 21 and a brush assembly 22. The nozzle assembly 21 includes multiple nozzles 211. The brush assembly 22 is distributed around the nozzles 211 and is arranged in an array on the annular area around the nozzles 211.

[0033] Furthermore, the nozzle assembly 21 includes a circular mounting plate 212 and a plurality of nozzles 211 and mounting holes 213 disposed on the mounting plate 212, and the brush assembly 22 is disposed in the mounting hole 213; specifically, the brush assembly 22 is inserted into the mounting hole 213 for fixation, thereby realizing the integrated layout of the brush assembly 22 and the nozzle assembly 21.

[0034] The spray gun 100 provided by this utility model has a ring-shaped array of brush components 22 around the nozzle 211. When there is something to be cleaned, water is sprayed from the nozzle 211 to rinse away the stains, while the array of brush components 22 forms a wrapping cleaning on the curved surfaces of the object to be cleaned (such as the curvature of tableware, bathroom corners, bicycles, cars, etc.). This solves the problem of insufficient cleaning power of traditional spray guns for adhering stains and effectively enhances the cleaning effect of the spray gun 100. When water is sprayed from the nozzle 211 onto the surface of the object to be cleaned, the ring-shaped brush components 22 simultaneously brush, realizing the simultaneous rinsing and brushing. Double cleaning can be completed in a single operation, improving the cleaning efficiency of the spray gun 100.

[0035] In one specific embodiment, the mounting hole 213 is a cylindrical mounting hole with a diameter of 5mm and a depth of 8mm, and the inner wall is provided with a guide groove (not shown).

[0036] Furthermore, the brush assembly 22 includes a plurality of mounting bases 221 and brush heads 222 disposed on the plurality of mounting bases 221. The mounting bases 221 are inserted into the mounting holes 213, ensuring the stable operation of the brush heads 222.

[0037] Specifically, the mounting base 221 of the brush assembly 22 is an ABS plastic cylinder with elastic claws. It is pressed into the mounting hole 213 by interference fit. After the mounting base 221 is embedded in the guide groove, it is rotated 15° to lock. When the spray gun 100 is working, this design can ensure that the brush head 222 does not shift under the impact of high-pressure water flow, and at the same time allows the damaged brush head 222 to be replaced individually.

[0038] Specifically, the center of the mounting hole 213 is 3mm away from the edge of the nozzle 211 outlet to prevent the brush head 222 from blocking the water flow path.

[0039] In one specific embodiment, the brush assembly 22 is an annular brush head 222 that is uniformly distributed at a preset density on the annular area of ​​the nozzle 211.

[0040] In this embodiment, a plurality of brush heads 222 are evenly distributed on the annular area of ​​the nozzle 211. By arranging the brush heads 222 at equal intervals, the brush heads 222 can form a continuous friction band when cleaning curved surfaces (such as the inner wall of a dish), avoiding cleaning dead corners and enhancing the cleaning effect of the spray gun 100.

[0041] Specifically, the brush head 222 is composed of brush filaments with a diameter of 0.15 mm. Each bundle of brush head 222 contains 120 brush filaments. Each brush filament is embedded into the top groove of the mounting base 221 (not shown) by heat fusion. The brush filaments are 30 mm long and spread out radially in the free state. When the brush head 222 is pressed, it forms a 15° tilt angle to enhance the scraping force. A single bundle of brush head 222 can withstand a radial load of 50 N.

[0042] In one embodiment, the cleaning brush head 20 further includes an annular housing 23 and a fixed base 24, the annular housing 23 and the fixed base 24 being coaxial and rotatably connected; the annular housing 23 and the fixed base 24 are detachably disposed.

[0043] Specifically, the mounting base 24 is cylindrical, and the water inlet end of the mounting base 24 is fixedly connected to the spray gun body 10 to receive the water flow delivered by the spray gun body 10 and transmit the water flow to the nozzle assembly 21.

[0044] Multiple nozzles 311 on the nozzle assembly 21 are arranged around the center of the mounting plate 212.

[0045] Furthermore, the annular housing 23 is fitted onto the annular side of the mounting plate 212. Rotating the annular housing 23 causes the mounting plate 212 to rotate, thereby switching between different nozzles 211.

[0046] Specifically, a keyway (not shown) is provided on the side of the mounting plate 212, and a convex key (not shown) is embedded in the inner wall of the annular housing 23. The convex key and the keyway are fitted together with a gap, and the convex key can rotate along the length of the keyway. When the annular housing 23 is rotated, the convex key rotates along the length of the keyway to drive the mounting plate 212 to rotate. The rotation of the mounting plate 212 causes the nozzles 211 of different models on the mounting plate 212 to be misaligned, thereby achieving the purpose of switching the nozzles 211.

[0047] Furthermore, the spray gun 100 can switch between different water spray patterns by rotating the nozzle 211 according to usage needs. When the nozzle 211 is switched to the shower mode, the water flow is large, the flow rate is slow, the area is large and the distribution is even, and the water will not splash, making it suitable for washing cars or bathing pets.

[0048] The annular housing 23 can rotate 360 ​​degrees on the side of the mounting plate 212.

[0049] In one embodiment, the spray gun body 10 includes a connector 11 and an anti-slip handle 12, with the connector 11 and the anti-slip handle 12 fixedly connected, and the water outlet end of the connector 11 fixedly connected to the fixing base 24. The spray gun body 10 also includes a water outlet switch 13 for connecting and closing the connector 11 with the water pipe.

[0050] Furthermore, the water outlet switch 13 includes a valve operating rod 131, a valve core 133, and a handle portion 132. The valve core 133 is disposed inside the connector 11. The valve operating rod 131 is connected to the valve core 133. The handle portion 132 controls the valve operating rod 131 to open or close the valve core 133.

[0051] Specifically, the interior of the connector 11 is a water flow channel, and a valve groove (not shown) is provided on one side of the inner wall of the connector 11. When the handle 132 operates the valve operating rod 131 to open the valve core 133, the valve core 133 is embedded in the valve groove, and the water supply channel inside the connector 11 is opened to allow water to flow through. Conversely, the water supply channel is closed.

[0052] The valve core 133 can be hemispherical.

[0053] Furthermore, a water pipe connector 30 is provided at the bottom of the anti-slip handle 12, and an external water pipe is connected to the spray gun 100 through the water pipe connector 30; a connector 121 is also provided on the anti-slip handle 12, and the handle part 132 includes a pressing handle 1321 and an actuating end 1322. The handle part 132 is rotatably connected to the anti-slip handle 132 through the connector 121, so that when the pressing handle 1321 is pressed, the actuating end 1322 rotates around the connector 121, thereby pushing the valve operating rod 131 to adjust the valve core 133, so as to realize the water volume adjustment between the connector 11 and the water pipe.

[0054] Specifically, pressing the handle 1321 causes the actuator 1322 of the handle 132 to rotate clockwise around the connector 121, thereby pushing the valve operating rod 131 to pull the valve core 133 out of the valve groove, opening the water supply channel. Water flows through the water supply channel in the connector 11 to the nozzle assembly 21, and then sprays outward from the nozzle 211. Releasing the handle 1321 causes the actuator 1322 of the handle 132 to rotate counterclockwise around the connector 121, thereby pushing the valve operating rod 131 to push the valve core 133 into the valve groove, so that the valve core 133 on the valve operating rod 131 seals with the valve groove, thereby closing the water supply channel.

[0055] In one embodiment, the spray gun body 10 further includes an adjustable latch 14, which, when in a latched state, is used to hold the position of the actuator 1322, thereby enabling continuous water output.

[0056] Specifically, when the handle 1321 is pressed, the actuator 1322 of the handle 132 rotates clockwise around the connector 121, thereby pushing the valve operating rod 131 to pull the valve core 133 out of the valve groove and open the water supply channel. At this time, the latch 14 is moved to hold it at the actuator 1322 of the handle 132, thereby achieving a labor-saving effect.

[0057] Compared with the prior art, the spray gun 100 provided by this utility model has a ring-shaped array of brush components 22 around the nozzle 211. When there is something to be cleaned, water is sprayed from the nozzle 211 to rinse away the stains, while the array of brush components 22 forms a wrapping cleaning on the curved surfaces of the object to be cleaned (such as the curvature of tableware, bathroom corners, bicycles, cars, etc.). This solves the problem of insufficient cleaning power of traditional spray guns for adhering stains and effectively enhances the cleaning effect of the spray gun 100. When water is sprayed from the nozzle 211 onto the surface of the object to be cleaned, the ring-shaped brush components 22 simultaneously brush, realizing the simultaneous rinsing and brushing. Double cleaning can be completed in a single operation, improving the cleaning efficiency of the spray gun 100.

[0058] Obviously, the above embodiments are merely examples for the detailed description of this utility model, and are not intended to limit the implementation. This utility model can be implemented in many other ways different from those described herein. Although the embodiments of this utility model have been described in conjunction with the accompanying drawings, those skilled in the art can make other modifications and variations based on the above description, and such modifications and variations still fall within the protection scope defined by the appended claims.
