[0038] Please refer to Figures 1, 2 and 3. Figure 1 is a schematic diagram of the structure of the spray gun 10 in some embodiments, Figure 2 is a schematic diagram of the structure of the spray gun 10 in some embodiments with the housing 11 omitted, and Figure 3 is a schematic diagram of the structure of some components of the spray gun 10 in some embodiments. The spray gun 10 provided in this application can be used in a toilet. The housing 11 of the spray gun 10 is provided with a water outlet 111, and the water outlet 111 of the spray gun 10 can spray cleaning water. The toilet also includes a toilet seat, which is provided with a toilet bowl. The spray gun 10 is arranged on the toilet seat and can move relative to the toilet seat so that the water outlet 111 extends into the toilet bowl, so as to spray the user. The spray gun 10 can also move relative to the toilet seat and be accommodated in the toilet seat. Of course, the application of the spray gun 10 is not limited to the records of this application, and the spray gun 10 can also be used in any other applicable scenes that require spraying.

[0039] As shown in FIG. 2, FIG. 3 and FIG. 4, in some embodiments, the spray gun 10 further includes a frame 12, a water inlet pipe 13, and a spray head 14. The frame 12 is at least partially disposed in the housing 11 and fixedly connected to the housing 11. The spray head 14 is rotatably disposed on the frame 12 and located in the housing 11. The spray head 14 includes a main body 141 and a plurality of nozzles 142. The plurality of nozzles 142 are sequentially arranged at intervals along the circumference of the main body 141 and are all connected to the water inlet pipe 13. The other end of the water inlet pipe 13 is used to connect to an external water source, such as a water tank or a liquid storage tank connected to a toilet. The position of the nozzle 142 in the circumferential direction of the main body 141 corresponds to the water outlet 111. In other words, when the main body 141 rotates relative to the frame 12 around the axis of the main body 141, the plurality of nozzles 142 can be sequentially opposite to the water outlet 111. At least two nozzles 142 have different water types, and the water type sprayed by the water outlet 111 is the same as the water type of the nozzle 142 opposite to the water outlet 111. When the two nozzles 142 with different water types are respectively corresponding to the water outlet 111, the spray gun 10 can spray cleaning water of different water types. Therefore, the water type of the spray gun 10 can be switched by rotating the main body 141 relative to the frame 12, without the need to set a complex reversing element such as a reversing valve, which is conducive to simplifying the structure of the spray gun 10, compressing the volume of the spray gun 10, and reducing the preparation cost of the spray gun 10.

[0040] It should be noted that, in the present application, the description of the different water patterns of the two nozzles 142 can be understood as the different shapes and / or sizes of the cross-sections of the washing water sprayed from the two nozzles 142. The different water patterns of the two nozzles 142 can be achieved by setting the shapes and / or sizes of the openings of the two nozzles 142 to be different, so as to change the water pattern of the washing water sprayed through the openings of the nozzles 142.

[0041] In some embodiments, the spray gun 10 further includes a rotating wheel 15, which is disposed on the frame 12 and located in the housing 11. The rotating wheel 15 is connected to the main body 141 and is coaxially disposed with the main body 141. The rotating wheel 15 can rotate relative to the frame 12 around the axis of the main body 141 to drive the main body 141 to rotate. The water type can be switched by driving the rotating wheel 15 to rotate. Further, in some embodiments, the rotating wheel 15 is provided with a plurality of chutes 151 along the circumferential side. The chutes 151 have a first end 1511 close to the main body 141 and a second end 1512 away from the main body 141 in the axial direction of the main body 141. The first end 1511 and the second end 1512 are spaced apart in the circumferential direction of the main body 141. The spray gun 10 further includes a sliding structure 16 and a driving element 17. The sliding structure 16 is inserted into the slide groove 151 and at least partially located at the first end position 1511. The driving element 17 is used to drive the sliding structure 16 to move along the axial direction of the main body 141, so as to slide from the first end position 1511 to the second end position 1512. It can be understood that since the first end position 1511 and the second end position 1512 are arranged at intervals in the circumferential direction of the main body 141, when the sliding structure 16 moves along the axial direction of the main body 141, the sliding of the sliding structure 16 in the slide groove 151 can cause the sliding structure 16 to apply a force to the side wall of the slide groove 151, thereby driving the rotating wheel 15 to rotate relative to the frame 12 around the axis. In other words, the linear motion of the sliding structure 16 can be converted into the rotational motion of the rotating wheel 15 by the arrangement of the slide groove 151.

[0042] In some embodiments, the rotation stroke from the first end position 1511 to the second end position 1512 in the circumferential direction of the main body 141 is equal to the rotation stroke of the two adjacent nozzles 142 in the circumferential direction of the main body 141. In other words, when one of the nozzles 142 is opposite to the water outlet 111, if the driving element 17 drives the sliding structure 16 to slide from the first end position 1511 along the slide groove 151 to the second end position 1512, the rotation stroke of the wheel 15 can just drive the main body 141 to rotate relative to the shell 11 until the other nozzle 142 adjacent to the nozzle 142 is opposite to the water outlet 111, thereby realizing the switching of the water type of the spray gun 10.

[0043] In the above-mentioned spray gun 10, when the driving element 17 drives the sliding structure 16 to move along the axial direction of the main body 141, the sliding of the sliding structure 16 along the slide groove 151 can drive the rotating wheel 15 to drive the spray head 14 to rotate around the axial direction. When the sliding structure 16 slides from the first end position 1511 of one of the slide grooves 151 to the second end position 1512, the rotation stroke of the spray head 14 relative to the housing 11 is exactly equal to the rotation stroke of the two adjacent nozzles 142 in the circumferential direction of the main body 141, so that different nozzles 142 can be switched to be opposite to the water outlet 111. When the nozzles 142 of different water outlet water types are opposite to the water outlet 111, the water outlet 111 of the spray gun 10 can spray cleaning water of different water types. Therefore, the above-mentioned spray gun 10, through the design of the slide groove 151 structure of the rotating wheel 15, can drive the spray gun 10 to achieve water type switching through the linear movement of the sliding structure 16, so that the structure of the driving mechanism of the spray gun 10 is simple and the preparation cost is low. At the same time, the rotating wheel 15 drives the nozzle 14 to rotate around the axis to achieve the switching of water types. There is no need to use complex reversing valves and other reversing elements to achieve water type switching, which is beneficial to simplify the structure of the spray gun 10, compress the volume of the spray gun 10, and reduce the preparation cost of the spray gun 10.

[0044] In some embodiments, the spray gun 10 further includes a cover 18 disposed in the housing 11, and the spray head 14 is rotatably disposed in the cover 18, and the cover 18 can provide a limiting and protective function for the spray head 14. The frame 12 includes a body 121 and a terminal 122 connected to one end of the body 121, the cover 18 and the spray head 14 are integrally disposed on the terminal 122, and the rotating wheel 15 is rotatably disposed on the side of the terminal 122 facing away from the spray head 14. The spray gun 10 further includes a connecting shaft 19, which passes through the cover 18 and the terminal 122, and the two ends of the connecting shaft 19 are respectively inserted into the body 141 and the rotating wheel 15 to be fixedly connected to the body 141 and the rotating wheel 15. With such arrangement, the wheel 15 can drive the nozzle 14 to rotate through the connecting shaft 19 when rotating, and can also isolate the space where the wheel 15 is located from the space where the nozzle 14 and the cover body 18 are located, thereby preventing moisture in the space where the nozzle 14 is located from interfering with the wheel 15 and other components on the side of the end portion 122 facing away from the nozzle 14.

[0045] In some embodiments, the cover body 18 includes a seat body portion 181 and a cover plate portion 182, the seat body portion 181 is arranged on the end portion 122, the nozzle 14 is arranged on the seat body portion 181, and the cover plate portion 182 is covered on the nozzle 14 and fixedly connected to the seat body portion 181. A first channel 1411 is provided in the main body 141 to connect multiple nozzles 142. The first channel 1411 can be an annular channel, a cavity or a connecting structure of other shapes provided in the main body 141, as long as it can connect multiple nozzles 142. A second channel 1412 is formed between the cover body 18 and the main body 141 to connect the first channel 1411. The frame 12 also includes a water inlet portion 123 provided on the side of the end portion 122 facing away from the nozzle 14, and the water inlet portion 123 connects the second channel 1412 and the water inlet pipe 13. It can be understood that when the spray gun 10 sprays cleaning water, one of the nozzles 142 is opposite to the water outlet 111, and the water from the external water source passes through the water inlet pipe 13, the water inlet part 123, the second channel 1412 and the first channel 1411 in sequence, and is sprayed out from the nozzle 142 opposite to the water outlet 111, and then sprayed out from the spray gun 10 through the water outlet 111.

[0046] In some embodiments, when one of the nozzles 142 is opposite to the water outlet 111, the nozzle 142 can be sealed and connected to the housing 11. In other words, water cannot pass through the gap between the nozzle 142 and the housing 11. Therefore, only the cleaning water sprayed by the nozzle 142 can be sprayed from the water outlet 111, and the water sprayed by other nozzles 142 cannot be sprayed from the gap between the nozzle 142 and the housing 11, which can improve the quality of the spray water pattern. Of course, the outlet of the nozzle 142 staggered from the water outlet 111 can also abut against the cover plate portion 182 or the housing 11 to block the outlet of other nozzles 142 when other nozzles 142 do not need to spray water.

[0047] As shown in combination with FIG. 3 and FIG. 5 , in some embodiments, the nozzle 14 may be provided with a plurality of nozzles 142 with different water discharge patterns, and the plurality of nozzles 142 are evenly distributed along the circumference of the main body 141, and the number of the nozzles 142 includes but is not limited to two, three, four, five, etc. The number of the chutes 151 is equal to the number of the nozzles 142, and in the circumference of the main body 141, any second end 1512 corresponds to the position of the first end 1511 of the adjacent chutes 151, in other words, the line connecting any second end 1512 and the first end 1511 of the adjacent chutes 151 is parallel to the axis of the main body 141. In some embodiments, the rotating wheel 15 is further provided with a plurality of connecting grooves 152 along the circumference, each connecting groove 152 is located between two adjacent chutes 151, and the connecting groove 152 connects the second end 1512 of one chutes 151 and the first end 1511 of the other chutes 151. Thus, when the driving element 17 drives the sliding structure 16 to slide from the first end position 1511 of one of the chutes 151 to the second end position 1512 to realize the switching of two adjacent nozzles 142, the driving element 17 can slide from the second end position 1512 of the chutes 151 to the first end position 1511 of another adjacent chutes 151 through the connecting groove 152, so that when the driving element 17 drives the sliding structure 16 to move along the axis of the main body 141 in a direction away from the main body 141 again, the driving element 17 can slide from the first end position 1511 of another chutes 151 to the second end position 1512 of another chutes 151. In this way, through the reciprocating motion of the sliding structure 16 in the axial direction of the main body 141, different nozzles 142 can be switched in sequence to be opposite to the water outlet 111, so as to realize the switching of multiple water types.

[0048] Further, in combination with FIG. 2 and FIG. 3 , in some embodiments, the connection groove 152 is arranged parallel to the axial direction of the main body 141, and the spray gun 10 further includes a reset element 21, which includes but is not limited to any applicable elastic element such as a spring, rubber, etc., and the reset element 21 is compressed during the sliding structure 16 sliding from the first end position 1511 to the second end position 1512. When the sliding structure 16 is located at the second end position 1512 and the driving element 17 stops applying force to the sliding structure 16, the elastic reset force of the reset element 21 can drive the sliding structure 16 to slide along the connection groove 152 to the first end position 1511 of the adjacent sliding groove 151, so as to realize the reset of the sliding structure 16 in the axial direction of the main body 141, so as to facilitate the sliding structure 16 to slide from the first end position 1511 to the second end position 1512 again to realize the switching of the nozzle 142.

[0049] In some embodiments, the spray gun 10 further includes a connecting rod 22, which is used to realize the transmission between the driving element 17 and the sliding structure 16. The connecting rod 22 includes a connecting portion 221 and a sliding portion 222, wherein the connecting portion 221 is connected to the sliding structure 16 and the sliding portion 222. The frame 12 further includes a sliding seat 124 connected to the main body 121, wherein the sliding portion 222 is penetrated through the sliding seat 124 and can slide relative to the sliding seat 124. The reset element 21 is disposed on the sliding portion 222, for example, sleeved on the sliding portion 222, and the two ends of the reset element 21 are respectively abutted against the connecting portion 221 and the sliding seat 124. It can be understood that when the driving element 17 drives the connecting rod 22 to move in the direction away from the main body 141 along the axial direction of the main body 141, the connecting portion 221 drives the sliding structure 16 to slide along the sliding groove 151, and the connecting portion 221 compresses the reset element 21 in the direction of the sliding seat 124, and the sliding portion 222 slides relative to the sliding seat 124. When the driving element 17 stops driving the connecting rod 22 to move, the elastic reset action of the reset element 21 can drive the connecting portion 221 to move toward the main body 141, thereby driving the sliding structure 16 to slide from the second end position 1512 through the connecting groove 152 to the first end position 1511 to achieve reset.

[0050] In some embodiments, the portion of the slide groove 151 between the first end position 1511 and the second end position 1512 is an arc groove, and the first end position 1511, the second end position 1512 and the connecting groove 152 can be connected to form a straight groove, which is beneficial to improving the stability of the movement process of the sliding structure 16 driving the rotating wheel 15 to rotate and the resetting movement process. The setting of the arc groove also enables the sliding structure 16 to continuously drive the rotating wheel 15 to rotate during the sliding process along the slide groove 151, and the sliding of the sliding structure 16 is smoother.

[0051] As shown in combination with Fig. 2, Fig. 3 and Fig. 6, in some embodiments, the spray gun 10 further includes a fixing seat 23 disposed in the housing 11, the fixing seat 23 is covered on the rotating wheel 15 and fixed to the main body 121 of the frame 12, and a limiting groove 231 is provided on the fixing seat 23, and the limiting groove 231 is parallel to the axial direction of the main body 141. The connecting rod 22 further includes a limiting protrusion 223 disposed on the connecting portion 221, and the limiting protrusion 223 is slidably disposed in the limiting groove 231. When the sliding structure 16 is located at the first end position 1511, the limiting protrusion 223 can be located at one end of the limiting groove 231 close to the main body 141, and when the sliding structure 16 slides from the first end position 1511 to the second end position 1512, the limiting protrusion 223 slides along the limiting groove 231 to one end away from the main body 141. Therefore, the fixed seat 23 can provide limiting and protection for the rotating wheel 15 and the connecting rod 22. The cooperation between the limiting groove 231 and the limiting protrusion 223 can also provide limiting effect on the sliding of the sliding structure 16, thereby improving the sliding accuracy and stability, thereby improving the stability of the water type switching function.

[0052] The specific configuration of the driving element 17 is not limited, as long as it can drive the connecting rod 22 to drive the sliding structure 16 to move in the axial direction of the main body 141 in the direction away from the main body 141. Please refer to Figures 2 and 3 again. In some embodiments, the connecting rod 22 also includes a driving portion 224 connected to the sliding portion 222. The driving element 17 is arranged on the main body 121 of the frame 12 and is located in the housing 11. The driving element 17 can be an electromagnet assembly. The driving element 17 has an output shaft 171 that can reciprocate in the axial direction of the main body 141. The driving portion 224 is connected to the output shaft 171. When the driving element 17 is in operation, it can drive the connecting rod 22 to move in the direction away from the main body 141 through the output shaft 171, thereby driving the sliding structure 16 to slide along the slide groove 151. Using an electromagnet assembly as the driving element 17 can effectively reduce the space occupied by the driving element 17, so that the driving element 17 can be integrated into the shell 11 of the spray gun 10. The driving element 17 will not be exposed from the shell 11. The shell 11 can also provide limiting and protection for the driving element 17, which is beneficial to improving the structural reliability of the appearance integrity of the spray gun 10.

The driving element 17 includes but is not limited to any applicable rotating driving device such as an electric motor. The driving element 17 has an output shaft 171 that can rotate by itself, and the output shaft 171 is perpendicular to the axial direction of the main body 141. The connecting rod 22 also includes a flexible transmission portion 225, one end of the flexible transmission portion 225 is connected to the sliding portion 222, and the other end is wound around the output shaft 171 of the driving element 17. The flexible transmission part 225 includes but is not limited to any suitable element such as a plastic rope. When the driving element 17 is running, the rotation of the output shaft 171 can drive the flexible transmission part 225 to move, such as increasing the size of the part of the flexible transmission part 225 wrapped around the output shaft 171, thereby pulling the connecting rod 22 through the flexible transmission part 225 to move in a direction away from the main body 141, thereby driving the sliding structure 16 to slide along the slide groove 151 to achieve water type switching.
