[0026] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0027] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0028] See also Figure 1 In one embodiment of the present application, a spray gun 100 for a smart toilet is provided, which is used to realize the cleaning function of the smart toilet. In this embodiment, the spray gun 100 includes a spray head 10 and a gun body 20.

[0029] The nozzle 10 includes a nozzle housing 11 and a water spray channel 1124 disposed inside the nozzle housing 11. A mounting position is provided at one end of the nozzle housing 11, and a fixing portion 111 is provided at the mounting position. The gun body 20 includes a gun body housing 21 and a water delivery channel 22 disposed inside the gun body housing 21, and one end of the gun body housing 21 is disposed at the mounting position of the nozzle housing 11. A matching portion 211 is provided at the end of the gun body housing 21 connected to the nozzle housing 11, and the matching portion 211 is engaged with the fixing portion 111, so that the gun body 20 and the nozzle 10 are detachably fixedly connected, and the water delivery channel 22 is connected to the water spray channel 1124.

[0030] Further, see Figures 2 to 6 The nozzle housing 11 of this embodiment includes a housing body 112 and an end cover body 113. One end of the housing body is open and has a mounting cavity 1121 therein. The housing body 112 is provided with a plurality of nozzle openings 1122, which are arranged at intervals, and the nozzle openings 1122 are used to spray liquid for use by users.

[0031] The multiple nozzle openings 1122 may include a female washing nozzle, a toilet washing nozzle, and a laxative nozzle to perform different functions accordingly. The female washing nozzle, the toilet washing nozzle, and the laxative nozzle may be arranged in a straight line on the shell body 112, and there is a gap between two adjacent nozzle openings 1122. This arrangement can avoid interference between nozzle openings 1122 with different functions during water spraying operations, thereby ensuring the user experience.

[0032] In this embodiment, a plurality of nozzle channels 1123 are provided inside the shell body 112. The plurality of nozzle channels 1123 are independent of each other, and each nozzle channel 1123 is correspondingly connected to a nozzle opening 1122. The two end openings of the nozzle channel 1123 are respectively a first port and a second port, wherein the first port of the nozzle channel 1123 is connected to the nozzle opening 1122.

[0033] The nozzle channel 1123 of this embodiment can be integrally formed inside the shell body 112 by a mold. The nozzle channel 1123 is a right-angle bend type, and the second port of the nozzle channel 1123 is used for water flow to enter. The water flow for spraying and washing enters the nozzle channel 1123 from the second port, and then sprays out from the corresponding nozzle port 1122 through the first port.

[0034] In this embodiment, a water spray channel 1124 is further provided inside the shell body 112, and the water spray channel 1124 can be integrally formed inside the shell body 112 by a mold. The water spray channel 1124 of this embodiment is L-shaped and includes an inlet end and an outlet end. The inlet end of the water spray channel 1124 is flush with the end surface of the shell body 112 with an opening, and the inlet end is used for the entry of water flow. The outlet end of the water spray channel 1124 is used to communicate with the second port of the nozzle channel 1123, so as to input the water flow in the water spray channel 1124 into the nozzle channel 1123.

[0035] Further, the end cover body 113 of the present embodiment includes a mounting portion 1131 and a connecting portion 1132 connected to an end surface of the mounting portion 1131. The mounting portion 1131 is open at both ends and hollow inside, and the cavity inside the mounting portion 1131 constitutes a receiving cavity 1133 of the end cover body 113. A through hole 1134 is provided at a position of the connecting portion 1132 corresponding to the opening of the end of the mounting portion 1131, and the outer side of the connecting portion 1132 protrudes outward from the outer peripheral side wall of the mounting portion 1131.

[0036] When the end cover 113 is connected to the shell body 112, the mounting portion 1131 is accommodated in the mounting cavity 1121 of the shell body 112, and the connecting portion 1132 is fixed on the end surface of the shell body 112 with an open end. In this embodiment, the end cover 113 and the shell body 112 are connected and fixed by fasteners. Specifically, fastening holes are provided at corresponding positions of the connecting portion 1132 and the end surface of the open end of the shell body 112, and the fasteners are inserted into the fastening holes to connect and fix the end cover 113 and the shell body 112. The fasteners can be bolts, pins, connecting shafts 133, etc.

[0037] It is understandable that in addition to being connected and fixed by fasteners, the end cover body 113 and the shell body 112 can also be fixed by snapping, magnetic attraction, etc. As long as the connection between the end cover body 113 and the shell body 112 can be guaranteed, the connection method between the two is not too limited here.

[0038] In this embodiment, a connection port 1135 is provided on the side wall of the mounting portion 1131. When the end cover 113 is connected to the shell body 112, the connection port 1135 is correspondingly connected to the outlet end of the water spray channel 1124 of the shell body 112, that is, the connection port 1135 on the end cover 113 is connected to the water spray channel 1124 via the outlet end. The water flow of the water spray channel 1124 can enter the accommodating cavity 1133 of the end cover 113 through the connection port 1135 and the outlet end.

[0039] Furthermore, the spray head 10 of this embodiment further comprises a rotary valve 13, which is disposed in the spray head housing 11. The rotary valve 13 has a water outlet 131 connected to the water spray channel 1124. The rotary valve 13 can rotate relative to the spray head housing 11, so that the water outlet 131 is selectively connected to one of the plurality of nozzle openings 1122.

[0040] In this embodiment, the rotary valve 13 is disposed in the accommodating cavity 1133 of the end cover body 113. The rotary valve 13 includes a transition portion 132 and a connecting shaft 133, wherein the connecting shaft 133 is connected to the end surface of the transition portion 132, and the water outlet 131 is provided on the transition portion 132. When the rotary valve 13 is installed in the accommodating cavity 1133, the outer peripheral side wall of the transition portion 132 abuts against the inner wall of the accommodating cavity 1133, and the free end of the connecting shaft 133 is passed through the through hole 1134 of the connecting portion 1132 and protrudes outward from the end surface of the connecting portion 1132.

[0041] The connecting shaft 133 of this embodiment is used to connect with the transmission shaft 231 of the driving component 23 in the smart toilet. Under the driving action of the driving component 23, the connecting shaft 133 can be driven to rotate so that the rotary valve 13 rotates around the axis of the connecting shaft 133, thereby changing the position of the water outlet 131 in the circumferential direction around the axis of the connecting shaft 133.

[0042] In this embodiment, the nozzle 10 further includes a valve body sealing ring 14, which is arranged around the outer periphery of the connecting shaft 133 in the rotary valve 13. An annular mounting groove is concavely provided on the outer peripheral side wall of the connecting shaft 133, and the valve body sealing ring 14 is arranged in the mounting groove.

[0043] When the rotary valve 13 is disposed in the accommodating cavity 1133 of the end cover body 113, the outer side of the valve body sealing ring 14 contacts the inner wall of the accommodating cavity 1133. The position of the valve body sealing ring 14 in the accommodating cavity 1133 is closer to the connecting portion 1132 of the end cover body 113 relative to the connecting port 1135 of the mounting portion 1131.

[0044] This arrangement enables the valve body sealing ring 14 to form a seal in the accommodating chamber 1133, preventing the water flowing into the accommodating chamber 1133 from the connecting port 1135 from leaking out through the opening end of the mounting portion 1131 and the through hole 1134 on the connecting portion 1132, thereby ensuring that the water in the accommodating chamber 1133 can only flow out through the water outlet 131 on the rotary valve 13.

[0045] Furthermore, the nozzle 10 further includes a diverter plate 15 , which is fixed relative to the nozzle housing 11 , and the diverter plate 15 is arranged on the end surface of the transition portion 132 away from the connecting shaft 133 .

[0046] In this embodiment, a connecting column is convexly provided on the end surface of the transition portion 132, and a connecting groove is provided at a corresponding position of the diverter plate 15, and the connecting column is clamped in the connecting groove, so that the diverter plate 15 is correspondingly arranged on the end surface of the transition portion 132. It can be understood that the connecting column can be convexly provided on the diverter plate 15, and correspondingly, the connecting groove can be opened on the end surface of the transition portion 132.

[0047] In this embodiment, a buckle groove 152 is provided on the outer peripheral side wall of the diverter disc 15, and a buckle portion 1136 is protruding from the end surface of the mounting portion 1131 of the end cover body 113 away from the connecting portion 1132. The rotary valve 13 is arranged in the receiving groove of the mounting portion 1131, and when the diverter disc 15 is located on the end surface of the rotary valve 13, the buckle portion 1136 on the end cover body 113 is clamped in the buckle groove 152 of the diverter disc 15, so that the diverter disc 15 is fixed in the nozzle housing 11.

[0048] When the rotary valve 13 rotates relative to the nozzle housing 11 under the drive of the intelligent toilet driving assembly 23 , the diverter plate 15 is fixed relative to the nozzle housing 11 due to the snap-fitting effect between the snap-fitting portion 1136 and the snap-fitting groove 152 .

[0049] The diverter plate 15 of this embodiment is provided with a plurality of diverter ports 153, which are arranged at intervals on the diverter plate 15. In this embodiment, the center of the diverter plate 15 corresponds to the axis of the connecting shaft 133 in the rotary valve 13. The plurality of diverter ports 153 are evenly spaced around the center of the diverter plate 15.

[0050] The plurality of diverter ports 153 on the diverter disk 15 are connected to the plurality of nozzle ports 1122 in a one-to-one correspondence. Specifically, the diverter ports 153 are connected to the second port of the nozzle channel 1123, so as to be connected to the corresponding nozzle ports 1122 through the nozzle channel 1123. When the rotary valve 13 rotates relative to the spray head housing 11, the water outlet 131 on the rotary valve 13 selectively connects to one of the diverter ports 153 on the diverter disk 15, so as to be connected to the corresponding nozzle port 1122 through the nozzle channel 1123, so as to spray water from the nozzle port 1122.

[0051] Furthermore, the nozzle 10 of this embodiment further includes a flow dividing seal ring 16, which is disposed on the end surface of the flow dividing plate 15 away from the rotary valve 13. The flow dividing ports 153 on the flow dividing plate 15 are arranged at intervals, and a sealing groove 154 is provided between two adjacent flow dividing ports 153, and the flow dividing seal ring 16 is adapted to be clamped in the sealing groove 154.

[0052] In this embodiment, a plurality of diverter ports 153 are evenly spaced around the center of the diverter plate 15. For a nozzle 10 having three nozzle ports 1122, three diverter ports 153 are provided on the diverter plate 15. The three diverter ports 153 are arranged on the diverter plate 15 at an angle of 120° between each other.

[0053] A sealing groove 154 is provided between two adjacent diversion openings 153 of the three diversion openings 153, and a sealing groove 154 is provided around the periphery of the three diversion openings 153. The shape of the diversion sealing ring 16 matches the shape of the sealing groove 154 on the diversion plate 15, and is in the shape of a steering wheel.

[0054] By arranging a diverter sealing ring 16 on the end face of the diverter disk 15, the diverter sealing ring 16 can form a seal at the diversion point of the diverter disk 15 to avoid interference of water flows between different diverter ports 153, thereby ensuring that the water flows in the diverter ports 153 flow into the nozzle channels 1123 correspondingly connected thereto, and then are sprayed out from the corresponding nozzle ports 1122.

[0055] In this embodiment, the nozzle 10 further includes a pipe joint 17, which protrudes from the end surface of the shell body 112 at one end of which an opening is provided. The interior of the pipe joint 17 of this embodiment is hollow, and one end opening of the pipe joint 17 is communicated with the inlet end of the water spray channel 1124, so that the water spray channel 1124 is connected with the interior of the pipe joint 17.

[0056] The end cover 113 is provided with an opening 1137 at a position corresponding to the pipe joint 17. When the end cover 113 is connected to the shell body 112, the pipe joint 17 on the shell body 112 is inserted into the opening 1137. The pipe joint 17 of this embodiment is used to communicate with the water inlet pipeline of the smart toilet so that water flows into the water spray channel 1124 through the interior of the pipe joint 17.

[0057] The nozzle 10 of this embodiment further includes a joint sealing ring 18, which is arranged around the outer periphery of the pipe joint 17, and the outer side of the joint sealing ring 18 is in conflict with the inner wall of the water delivery channel 22. In this embodiment, an annular assembly groove is provided on the side wall of the pipe joint 17, and the joint sealing ring 18 is arranged in the assembly groove.

[0058] In addition, the nozzle 10 of this embodiment further comprises a cover sealing ring 19 . The cover sealing ring 19 is disposed around the outer periphery of the mounting portion 1131 of the end cover 113 , and the outer side of the cover sealing ring 19 abuts against the inner wall of the mounting cavity 1121 of the shell body 112 .

[0059] In this embodiment, the cover body sealing ring 19 is disposed on the mounting portion 1131 between the connection port 1135 and the connection between the mounting portion 1131 and the connecting portion 1132. This arrangement enables the cover body sealing ring 19 to form a seal in the mounting cavity 1121, preventing the water flow entering the accommodating cavity 1133 from the connection port 1135 from leaking out through the through hole 1134 and the opening 1137 on the connecting portion 1132, thereby ensuring that the water flow in the water spray channel 1124 can only enter the accommodating cavity 1133 of the end cover body 113.

[0060] Furthermore, if Figure 1 as well as Figure 7 , Figure 8 As shown, the gun body 20 of this embodiment is used to cooperate with the spray head 10 , and the gun body 20 includes a gun body shell 21 , a water delivery channel 22 and a driving assembly 23 .

[0061] The gun body shell 21 has an assembly chamber 212 inside. The water delivery channel 22 is arranged inside the gun body shell 21 and is independent of the assembly chamber 212. The water delivery channel 22 is used to communicate with the water inlet pipeline of the smart toilet. The drive assembly 23 is arranged in the assembly chamber 212. The drive assembly 23 includes a transmission shaft 231, which can rotate around its own axis. One end of the transmission shaft 231 protrudes outward from the end surface of the gun body shell 21, and the transmission shaft 231 is used to be connected to the nozzle 10 in a transmission manner.

[0062] In this embodiment, when the gun body 20 is connected to the spray head 10 , the water delivery channel 22 is connected to the water spray channel 1124 , and the transmission shaft 231 is connected to the connecting shaft 133 of the rotary valve 13 in the spray head 10 .

[0063] The transmission shaft 231 rotates around its own axis to drive the connecting shaft 133 to rotate, so that the rotary valve 13 rotates as a whole, so that the water outlet 131 on the rotary valve 13 is connected to one of the multiple diversion ports 153 on the diversion disk 15. The water in the water inlet pipeline of the smart toilet flows into the water spray channel 1124 through the water delivery channel 22, and then enters the accommodating cavity 1133 of the end cover body 113 through the connecting port 1135, and enters the corresponding nozzle channel 1123 through the water outlet 131 and the diversion port 153 correspondingly connected thereto, and is then sprayed out from the nozzle port 1122 correspondingly connected to the nozzle channel 1123.

[0064] Furthermore, the driving assembly 23 of this embodiment further includes a driving motor 232, which includes a motor body 2321 and a driving shaft 2322 rotatably disposed on the motor body 2321. The driving shaft 2322 is connected to the transmission shaft 231 to drive the transmission shaft 231 to rotate.

[0065] In this embodiment, the driving motor 232 further includes a motor housing 2323. The motor housing 2323 is disposed on the periphery of the motor body 2321 to accommodate the motor body 2321 therein, thereby protecting the motor body 2321 and ensuring the normal operation of the driving motor 232 as a whole, thereby driving the nozzle 10. The driving shaft 2322 protrudes outward from the motor housing 2323 to be connected to the transmission shaft 231.

[0066] The gun body 20 of this embodiment further includes a rear plug 24, which is disposed at an end of the drive motor 232 away from the transmission shaft 231. The end surface of the rear plug 24 abuts against the end surface of the drive motor 232, and the outer side of the rear plug 24 abuts against the inner wall of the assembly cavity 212 of the gun body shell 21.

[0067] In this embodiment, the rear plug 24 is made of a flexible material, such as rubber, etc. When the drive motor 232 is working, it will generate a certain vibration. The setting of the rear plug 24 can offset and buffer the vibration of the drive motor 232 when working, avoid the vibration force from damaging the gun body shell 21, and ensure the overall stability of the gun body 20.

[0068] In addition, the gun body 20 of this embodiment further includes a shaft body sealing ring 25 . The shaft body sealing ring 25 is disposed around the outer circumference of the transmission shaft 231 , and the outer side of the shaft body sealing ring 25 is in conflict with the inner wall of the assembly cavity 212 .

[0069] In this embodiment, an annular fixing groove is provided on the outer circumference of the transmission shaft 231 , and a shaft body sealing ring 25 is disposed in the fixing groove to achieve sealing between the transmission shaft 231 and the gun body housing 21 .

[0070] Furthermore, the gun body 20 of this embodiment further includes a position sensor 26 . The position sensor 26 is disposed in the assembly cavity 212 , and the position sensor 26 is connected to the transmission shaft 231 to sense a rotation angle signal of the transmission shaft 231 .
