Detailed Description of the Invention

[0026] Typical embodiments embodying 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 variations in different embodiments, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are for illustrative purposes in nature and not intended to limit the present invention.

[0027] To further illustrate the principle and structure of the present invention, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0028] Referring to Figure 1 , an embodiment of the present application provides a spray gun 100 for a smart toilet, which is used to realize the cleaning function of the smart toilet. In this embodiment, the spray gun 100 includes a nozzle 10 and a gun body 20.

[0029] Among them, the nozzle 10 includes a nozzle housing 11 and a water spraying channel 1124 arranged inside the nozzle housing 11. One end of the nozzle housing 11 is provided with an installation position, and a fixing part 111 is arranged at the installation position. The gun body 20 includes a gun body housing 21 and a water conveying channel 22 arranged inside the gun body housing 21. One end of the gun body housing 21 is arranged at the installation position of the nozzle housing 11. The end of the gun body housing 21 connected to the nozzle housing 11 is provided with a fitting part 211, and the fitting part 211 is clamped and matched with the fixing part 111, so that the gun body 20 and the nozzle 10 are detachably and fixedly connected, and the water conveying channel 22 is communicated with the water spraying channel 1124.

[0030] Furthermore, referring toFigures 2 to 6 In this embodiment, the nozzle housing 11 includes a housing main body 112 and an end cover body 113. Among them, one end of the housing main body is open and has an installation cavity 1121 inside. A plurality of nozzle openings 1122 are formed on the housing main body 112, and the plurality of nozzle openings 1122 are arranged at intervals. The nozzle openings 1122 are used to eject liquid for the user to use.

[0031] The plurality of nozzle openings 1122 may include a feminine wash nozzle, a bidet nozzle, and a defecation nozzle to perform different functions accordingly. The feminine wash nozzle, the bidet nozzle, and the defecation nozzle may be arranged in a straight line on the housing main body 112, and there is an interval between two adjacent nozzle openings 1122. This setting can avoid the interference of nozzle openings 1122 with different functions during the water spraying operation and ensure the user experience.

[0032] In this embodiment, a plurality of nozzle channels 1123 are provided inside the housing main body 112. The plurality of nozzle channels 1123 are independent of each other, and each nozzle channel 1123 is correspondingly communicated with a nozzle opening 1122. The two open ends of the nozzle channel 1123 are the first port and the second port respectively. Among them, the first port of the nozzle channel 1123 is communicated with the nozzle opening 1122.

[0033] The nozzle channel 1123 of this embodiment can be integrally formed inside the housing main body 112 by a mold. The nozzle channel 1123 is in a right-angle bending shape, and the second port of the nozzle channel 1123 is for the entry of water flow. The water flow for spraying enters the nozzle channel 1123 from the second port and then sprays out from the corresponding nozzle opening 1122 through the first port.

[0034] In this embodiment, a water spraying channel 1124 is further provided inside the housing main body 112. The water spraying channel 1124 can be integrally formed inside the housing main body 112 by a mold. The water spraying channel 1124 of this embodiment is in an L-shaped bending shape, and the water spraying channel 1124 includes an inlet end and an outlet end. The inlet end of the water spraying channel 1124 is flush with the end face of the end of the housing main body 112 where the opening is provided, and the inlet end is for the entry of water flow. The outlet end of the water spraying channel 1124 is for communicating with the second port of the nozzle channel 1123 to input the water flow in the water spraying channel 1124 into the nozzle channel 1123.

[0035] Furthermore, the end cover body 113 of this embodiment includes an installation part 1131 and a connection part 1132 connected to one end face of the installation part 1131. The installation part 1131 is open at both ends and hollow inside. The cavity inside the installation part 1131 constitutes the accommodation cavity 1133 of the end cover body 113. A through hole 1134 is provided at the position corresponding to the end opening of the installation part 1131 on the connection part 1132, and the outer side of the connection part 1132 protrudes outward from the outer peripheral side wall of the installation part 1131.

[0036] When the end cover body 113 is connected to the housing main body 112, the installation portion 1131 is received in the installation cavity 1121 of the housing main body 112, and the connection portion 1132 is fixed to the end face of the housing main body 112 at the end with an opening. In this embodiment, the end cover body 113 and the housing main body 112 are fixedly connected by fasteners. Specifically, fastening holes are provided at corresponding positions on the connection portion 1132 and the end face of the opening end of the housing main body 112, and the fasteners are passed through the fastening holes to fix the end cover body 113 and the housing main body 112. The fasteners can be bolts, pins, connection shafts 133, etc.

[0037] It can be understood that, in addition to being fixedly connected by fasteners, the end cover body 113 and the housing main body 112 can also be snap-connected and magnetically attracted, etc., as long as the connection between the end cover body 113 and the housing main body 112 can be ensured, and the connection method between the two is not limited too much here.

[0038] In this embodiment, a connection port 1135 is provided on the side wall of the installation portion 1131. When the end cover body 113 is connected to the housing main body 112, the connection port 1135 is correspondingly communicated with the outlet end of the water spraying channel 1124 of the housing main body 112, that is, the connection port 1135 on the end cover body 113 is communicated with the water spraying channel 1124 via the outlet end. The water flow in the water spraying channel 1124 can enter the accommodation cavity 1133 of the end cover body 113 through the connection port 1135 and the outlet end.

[0039] Furthermore, the spray head 10 of this embodiment further includes a rotary valve 13, and the rotary valve 13 is arranged in the spray head housing 11. The rotary valve 13 has a water outlet 131 communicated with the water spraying channel 1124. The rotary valve 13 can rotate relative to the spray head housing 11 so that the water outlet 131 selectively communicates with one of a plurality of nozzle openings 1122.

[0040] In this embodiment, the rotary valve 13 is arranged in the accommodation cavity 1133 of the end cover body 113. The rotary valve 13 includes a transition portion 132 and a connection shaft 133. The connection shaft 133 is connected to the end face 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 accommodation cavity 1133, the outer peripheral side wall of the transition portion 132 abuts against the inner wall of the accommodation cavity 1133, and the free end of the connection shaft 133 passes through the through hole 1134 of the connection portion 1132 and protrudes out of the end face of the connection portion 1132.

[0041] The connection shaft 133 of this embodiment is used to be connected to the transmission shaft 231 of the driving assembly 23 in the intelligent toilet. Under the driving action of the driving assembly 23, the connection shaft 133 can be driven to rotate, so that the rotary valve 13 rotates around the axis of the connection shaft 133, thereby changing the position of the water outlet 131 in the circumferential direction around the axis of the connection 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] In the present embodiment, a plurality of diversion openings 153 are formed in the diversion plate 15, and the plurality of diversion openings 153 are arranged at intervals on the diversion plate 15. In the present embodiment, the center of the diversion plate 15 corresponds to the axis of the connecting shaft 133 in the rotary valve 13. The plurality of diversion openings 153 are evenly arranged at intervals around the center of the diversion plate 15.

[0050] The plurality of diversion openings 153 on the diversion plate 15 are in one-to-one communication with the plurality of nozzle openings 1122. Specifically, the diversion opening 153 is in communication with the second port of the nozzle passage 1123 to communicate with the corresponding nozzle opening 1122 through the nozzle passage 1123. When the rotary valve 13 rotates relative to the nozzle housing 11, the water outlet 131 on the rotary valve 13 selectively communicates with one of the diversion openings 153 on the diversion plate 15, so as to communicate with the corresponding nozzle opening 1122 through the nozzle passage 1123, and water flow is ejected from the nozzle opening 1122.

[0051] Furthermore, the nozzle 10 of the present embodiment further includes a diversion sealing ring 16, and the diversion sealing ring 16 is arranged on the end face of the diversion plate 15 facing away from the rotary valve 13. The diversion openings 153 on the diversion plate 15 are arranged at intervals, and a sealing groove 154 is provided between two adjacent diversion openings 153. The diversion sealing ring 16 is adaptively clamped in the sealing groove 154.

[0052] In the present embodiment, the plurality of diversion openings 153 are evenly arranged at intervals around the center of the diversion plate 15. For the nozzle 10 having three nozzle openings 1122, three diversion openings 153 are correspondingly provided on the diversion plate 15. The three diversion openings 153 are arranged on the diversion plate 15 at an angle of 120° between every two of them.

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

[0054] By providing the diversion sealing ring 16 on the end face of the diversion plate 15, the diversion sealing ring 16 can form a seal at the diversion of the diversion plate 15, avoid the interference of water flow between different diversion openings 153, ensure that the water flow in the diversion openings 153 correspondingly flows into the corresponding nozzle passages 1123 connected thereto, and then is ejected from the corresponding nozzle openings 1122.

[0055] In the present embodiment, the nozzle 10 further includes a pipe joint 17, and the pipe joint 17 protrudes on the end face of one end of the housing body 112 provided with an opening. The interior of the pipe joint 17 of the present embodiment is hollow, and one end opening of the pipe joint 17 is in communication with the inlet end of the water spraying passage 1124, so that the water spraying passage 1124 is connected to the interior of the pipe joint 17.

[0056] An opening 1137 is provided at the position of the end cap body 113 corresponding to the pipe joint 17. When the end cap body 113 is connected to the shell main body 112, the pipe joint 17 on the shell main body 112 penetrates through this opening 1137. The pipe joint 17 in this embodiment is used to communicate with the water inlet pipeline of the intelligent toilet, so that water can enter the water spraying channel 1124 through the inside of the pipe joint 17.

[0057] The spray head 10 in this embodiment further includes a joint sealing ring 18. The joint sealing ring 18 is arranged around the outer periphery of the pipe joint 17, and the outer side of the joint sealing ring 18 abuts against the inner wall of the water transmission channel 22. In this embodiment, an annular assembly groove is formed on the side wall of the pipe joint 17, and the joint sealing ring 18 is arranged in this assembly groove.

[0058] In addition, the spray head 10 in this embodiment further includes a cap body sealing ring 19. The cap body sealing ring 19 is arranged around the outer periphery of the installation part 1131 of the end cap body 113, and the outer side of the cap body sealing ring 19 abuts against the inner wall of the installation cavity 1121 of the shell main body 112.

[0059] In this embodiment, the setting position of the cap body sealing ring 19 on the installation part 1131 is located between the connection port 1135 and the connection part of the installation part 1131 and the connection part 1132. Such a setting can enable the cap body sealing ring 19 to form a seal in the installation cavity 1121, preventing the water flow entering the accommodation cavity 1133 from the connection port 1135 from leaking out through the through hole 1134 and the opening 1137 on the connection part 1132, and ensuring that the water flow in the water spraying channel 1124 can only enter the accommodation cavity 1133 of the end cap body 113.

[0060] Furthermore, as Figure 1 and Figure 7 、 Figure 8 shown, the gun body 20 in this embodiment is used to cooperate with the spray head 10. The gun body 20 includes a gun body housing 21, a water transmission channel 22 and a driving assembly 23.

[0061] Among them, an assembly cavity 212 is provided inside the gun body housing 21. The water transmission channel 22 is arranged inside the gun body housing 21 and is independent of the assembly cavity 212. The water transmission channel 22 is used to communicate with the water inlet pipeline of the intelligent toilet. The driving assembly 23 is arranged in the assembly cavity 212. The driving assembly 23 includes a transmission shaft 231, and the transmission shaft 231 can rotate around its own axis. One end of the transmission shaft 231 protrudes outward from the end face of the gun body housing 21, and the transmission shaft 231 is used for driving connection with the spray head 10.

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

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

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

[0065] In this embodiment, the drive motor 232 further includes a motor housing 2323. The motor housing 2323 is arranged on the outer periphery of the motor body 2321 to accommodate the motor body 2321 inside it, realizing the protection of the motor body 2321, ensuring the normal operation of the entire drive motor 232, and realizing the drive of the nozzle 10. The drive shaft 2322 protrudes outward from the motor housing 2323 for connection with the transmission shaft 231.

[0066] The gun body 20 of this embodiment further includes a rear plug 24, and the rear plug 24 is arranged at one end of the drive motor 232 away from the transmission shaft 231. The end face of the rear plug 24 abuts against the end face 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 housing 21.

[0067] In this embodiment, the rear plug 24 is made of a flexible material such as rubber. 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 when the drive motor 232 is working, avoid damage to the gun body housing 21 caused by the vibration force, and ensure the overall stability of the gun body 20.

[0068] In addition, the gun body 20 of this embodiment further includes a shaft seal ring 25. The shaft seal ring 25 is arranged around the outer periphery of the transmission shaft 231, and the outer side of the shaft seal ring 25 abuts against the inner wall of the assembly cavity 212.

[0069] In this embodiment, an annular fixing groove is provided on the outer periphery of the transmission shaft 231. The shaft seal ring 25 is arranged in the fixing groove to realize the seal between the transmission shaft 231 and the gun body housing 21.

[0070] Further, 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 the rotation angle signal of the transmission shaft 231.

[0071] The position sensor 26 is used to be electrically connected to the controller of the intelligent toilet, so that the position sensor 26 transmits the rotation angle signal to the controller. The controller is electrically connected to the drive motor 232, so that the controller electrically controls the rotation angle of the drive shaft 2322 according to the rotation angle signal.

[0072] Compared with the traditional stepper motor, the drive motor 232 of this embodiment combined with the position sensor 26 can not only achieve the function of the stepper motor, but also ensure the accuracy of position angle detection, reduce the cost of the motor at the same time, and can avoid the problem of high noise caused by the stepper motor, with stronger practicability.

[0073] After the gun body 20 of this embodiment is connected to the nozzle 10, the water delivery channel 22 is communicated with the water spraying channel 1124, and the transmission shaft 231 is docked with the connecting shaft 133 of the rotary valve 13 in the nozzle 10. The drive motor 232 operates, and the drive shaft 2322 rotates to drive the transmission shaft 231 to rotate, so that the connecting shaft 133 of the nozzle 10 rotates, thereby causing the whole rotary valve 13 to rotate. When the rotary valve 13 rotates, the water outlet 131 on the rotary valve 13 is communicated with a water diversion port 153 on the water diversion disc 15, so that the water spraying channel 1124 is communicated with one of the nozzle channels 1123.

[0074] The water flow in the water inlet pipeline of the intelligent toilet flows into the water spraying channel 1124 through the water delivery channel 22, 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 correspondingly communicated water diversion port 153, and is thus sprayed out from the nozzle port 1122 corresponding to the nozzle channel 1123.

[0075] The assembly cavity 212 inside the gun body 20 of this embodiment is provided with a water delivery channel 22 and a drive assembly 23. The water delivery channel 22 and the drive assembly 23 are integrally arranged, which can realize the reasonable utilization of the internal space of the gun body 20 and is conducive to the miniaturization design of the gun body 20. At the same time, only one water delivery channel 22 is provided inside the gun body 20, reducing the number of pipelines inside the gun body 20. Under the cooperation of the drive assembly 23, the conversion of the cleaning mode can be realized by changing the communication position of one water delivery channel 22, effectively simplifying the switching method and avoiding the accumulation of cold water in the pipeline, thus improving the user experience.

[0076] Further, a fixing portion 111 is provided at the installation position of the nozzle housing 11 of the nozzle 10 in this embodiment. A mating portion 211 is provided at the end of the gun body housing 21 of the gun body 20 connected to the nozzle housing 11. The mating portion 211 is snap-fitted with the fixing portion 111 so that the gun body 20 and the nozzle 10 are detachably and fixedly connected.

[0077] The detachable connection between the gun body 20 and the nozzle 10 enables the diversification of the structure of the intelligent toilet spray gun 100. Users can replace different nozzles 10 according to specific needs to expand the cleaning modes of the intelligent toilet, increase the choices for users during cleaning, and enhance the user experience.

[0078] In this embodiment, the fixing portion 111 is a buckle protruding from the end face of the nozzle housing 11, and the mating portion 211 is a card slot provided on the outer side wall of the gun body housing 21. The buckle is snap-fitted with the card slot, thereby realizing the detachable connection between the gun body 20 and the nozzle 10.

[0079] It can be understood that the fixing portion 111 can be a card slot provided on the outer side wall of one end of the nozzle housing 11, and the mating portion 211 is a buckle protruding from the end face of the gun body housing 21. The buckle is snap-fitted with the card slot to enable the detachable connection between the gun body 20 and the nozzle 10.

[0080] Further, the buckle in this embodiment includes a clamping arm 1111 and a clamping claw 1112. One end of the clamping arm 1111 is connected to the nozzle housing 11, and the clamping claw 1112 is connected to the other end of the clamping arm 1111. The two sides of the clamping claw 1112 extend outwards from the side wall of the clamping arm 1111, so that the buckle is in a T shape as a whole.

[0081] The card slot includes a first clamping area 2111 and a second clamping area 2112 that are connected. The shape of the first clamping area 2111 is adapted to the clamping arm 1111, and the shape of the second clamping area 2112 is adapted to the clamping claw 1112.

[0082] When the buckle is snap-fitted with the card slot, the clamping arm 1111 corresponds to the first clamping area 2111, and the clamping claw corresponds to the second clamping area 2112. The setting that the two sides of the clamping claw 1112 extend outwards from the side wall of the clamping arm 1111 enables the buckle to be stably snap-fitted in the card slot, preventing the buckle from coming out of the card slot, ensuring the stable connection between the nozzle 10 and the gun body 20, and guaranteeing the stability of the overall structure of the spray gun 100.

[0083] In this embodiment, there are multiple fixing portions 111 and multiple mating portions 211. Among them, the multiple fixing portions 111 are arranged at intervals on the installation position of the nozzle housing 11, and the multiple mating portions 211 are arranged at intervals on the connection end of the gun body housing 21.

[0084] The number of the fixing parts 111 corresponds to that of the mating parts 211, and their positions correspond to each other. The arrangement of the plurality of fixing parts 111 and the plurality of mating parts 211 can further ensure the stability of the connection between the gun body 20 and the nozzle 10, improve the connection strength between the two, and ensure the integrity of the spray gun 100.

[0085] In addition, an embodiment of the present application further provides an intelligent toilet, which includes a water inlet pipeline and the above-mentioned spray gun 100. Wherein, the water delivery channel 22 of the gun body 20 is communicated with the water inlet pipeline.

[0086] After the user selects the corresponding cleaning mode through the button on the intelligent toilet, the driving motor 232 is driven to work, the driving shaft 2322 rotates to drive the transmission shaft 231 to rotate, so that the connecting shaft 133 of the nozzle 10 rotates, and thus the rotary valve 13 rotates as a whole. When the rotary valve 13 rotates, the water outlet 131 on the rotary valve 13 is communicated with a diversion port 153 on the diversion disk 15, so that the water spray channel 1124 is communicated with one of the nozzle channels 1123. The water flow in the water inlet pipeline of the intelligent toilet enters the water spray channel 1124 through the water delivery channel 22, then enters the accommodating cavity 1133 of the end cover body 113 through the connection port 1135, and enters the corresponding nozzle channel 1123 through the water outlet 131 and the corresponding diversion port 153 communicated therewith, and thus is sprayed out from the nozzle port 1122 corresponding to the nozzle channel 1123 to clean the user, realizing the corresponding cleaning function selected by the user.
