Description

Technical Field

[0001] The present application relates to the technical field of spray guns, and in particular to a spray gun system and a toilet that do not require a built-in motor. Background Art

[0002] Smart toilets are usually equipped with a spray gun system, which is installed on the toilet seat. The spray gun in the spray gun system can be driven by a motor or other driving element to extend into the toilet bowl and spray cleaning water to the user to improve the user experience. In order to enrich the function of the spray gun and meet the different needs of users, the water type of the spray gun is usually switchable. When in use, different water types can be switched according to the user's needs for spraying.

[0037] See Figure 1 、 Figure 2 and Figure 3 , Figure 1 FIG. 1 is a schematic structural diagram of the spray gun system 10 when the spray gun 20 is in the first state in some embodiments. Figure 2 FIG. 1 is a schematic structural diagram of the spray gun system 10 when the spray gun 20 is in the second state in some embodiments. Figure 3Schematic diagram of the structure of the spray gun 20 in some embodiments. The spray gun system 10 provided in the present application includes a bracket 11, a spray gun 20 and a driving element 12. The bracket 11 includes a main body 111 and a first matching portion 112 provided on the main body 111. The first matching portion 112 has an end surface 1122. The spray gun 20 is slidably arranged on the main body 111. The shell 21 of the spray gun 20 is provided with a water spray port 211. The driving element 12 is used to drive the spray gun 20 to slide relative to the bracket 11 so that the spray gun 20 has a first state and a second state. In the first state, the spray gun 20 can be located on the side of the virtual plane where the end surface 1122 is located facing the first matching portion 112. In the second state, the spray gun 20 extends from the end surface 1122, and the water spray port 211 is located on the side of the plane where the end surface 1122 is located facing away from the first matching portion 112.

[0038] The spray gun system 10 provided herein includes, but is not limited to, use in a toilet. The toilet may also include a toilet seat (not shown). The spray gun system 10 is disposed within the toilet seat, which is provided with a toilet bowl. A bracket 11 is receivable within the toilet seat, and a drive element 12 is configured to cause the spray gun 20 to slide relative to the bracket 11, extending out of the toilet seat or retracting into the toilet seat. In a first state, the spray gun 20 partially extends out of the toilet bowl, allowing the spray gun 20 to spray cleaning water through the water outlet 211 to spray the user. In a second state, the spray gun 20 is retracted within the toilet seat.

[0039] Further, combined with Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the spray gun 20 includes a housing 21, a spray head 22, a switching element 23, and a rod 24. The housing 21 is slidably disposed on the body 111. The spray head 22 and the switching element 23 are both disposed within the housing 21. Water sprayed by the spray head 22 can be ejected from a water outlet 211 of the housing 21. The switching element 23 is connected to the spray head 22. The rod 24 includes a rod portion 241 and a second mating portion 242 that are interconnected. The rod portion 241 is located within the housing 21 and engages with the switching element 23. The second mating portion 242 is at least partially located outside the housing 21. The direction from the first mating portion 112 to the second mating portion 242 can be parallel to the relative sliding direction of the spray gun 20. When the driving element 12 drives the spray gun 20 to slide relative to the bracket 11, the second mating portion 242 moves relative to the first mating portion 112 in the axial direction of the spray gun 20. When the driving element 12 drives the spray gun 20 to slide from the first state to the second state, the second matching portion 242 moves toward the direction close to the first matching portion 112. When the spray gun 20 slides to the second state, the second matching portion 242 is spaced apart from or just in contact with the first matching portion 112. The second matching portion 242 does not apply force to the first matching portion 112. In this state, the spray gun 20 can spray cleaning water through the water outlet 211 to spray the user.

[0040] It will be appreciated that in the second state, when the drive element 12 continues to drive the spray gun 20 so that the second mating portion 242 continues to move toward the first mating portion 112, the second mating portion 242 exerts a force on the first mating portion 112 along the axial direction of the spray gun 20, directed from the first mating portion 112 toward the second mating portion 242, thereby pushing the rod 24 to move axially relative to the housing 21 of the spray gun 20. In this application, the state in which the second mating portion 242 exerts a force on the first mating portion 112 is referred to as the third state of the spray gun 20. In the third state, the movement of the rod 24 relative to the housing 21 can drive the switching element 23 to move relative to the housing 21 through the contact and engagement between the rod 241 and the switching element 23, thereby driving at least a portion of the spray head 22 to move relative to the housing 21, thereby changing the water pattern of the spray gun 20 and implementing a water pattern switching function to meet the varying needs of users.

[0041] In the spray gun system 10, when the driving element 12 drives the spray gun 20 to slide relative to the bracket 11 until the second mating portion 242 abuts the first mating portion 112, if the spray gun 20 continues to slide relative to the housing 21, the first mating portion 112 can push the second mating portion 242 to move relative to the housing 21, thereby using the force of the first mating portion 112 on the second mating portion 242 to drive at least part of the movement of the spray head 22 through the rod portion 241 and the switching element 23, thereby achieving the switching of the water type of the spray head 22. As a result, the spray gun system 10 can achieve the switching of the water type by using the driving force of the driving element 12 used to drive the movement of the spray gun 20. There is no need to provide an additional motor in the spray gun 20 to achieve the water type switching function, which is conducive to reducing the volume of the spray gun 20 and reducing the production cost of the spray gun 20.

[0042] In some embodiments, the first mating portion 112 may be circumferentially disposed around the housing 21, with the outer circumferential surface of the housing 21 slidingly engaged with the inner circumferential surface of the first mating portion 112. The first mating portion 112 can limit the movement of the housing 21 relative to the bracket 11. The first mating portion 112 may be provided with a protrusion 1121 that opposes the second mating portion 242. In the third state, the protrusion 1121 of the first mating portion 112 contacts the second mating portion 242 and applies a force to the second mating portion 242.

[0043] refer to Figure 4 and Figure 5As shown, in some embodiments, the spray gun 20 further includes a frame 25, at least a portion of which is disposed within the housing 21. At least a portion of the spray head 22 and the switching element 23 are rotatably disposed on the frame 25. A rod 24 is slidably disposed on the frame 25, and the sliding direction of the rod 24 relative to the frame 25 is parallel to the axial direction of the spray gun 20. When the first mating portion 112 pushes the second mating portion 242 to move relative to the housing 21 and the frame 25, the contact and engagement between the rod 241 and the switching element 23 can drive the switching element 23 to rotate about the axial direction, thereby driving at least a portion of the spray head 22 to rotate about the axis, thereby achieving the function of switching the water pattern.

[0044] In some embodiments, the switching element 23 is provided with at least two chutes 231 along its circumference. The chutes 231 have a first end 2311 proximal to the nozzle 22 and a second end 2312 distal to the nozzle 22. The first end 2311 and the second end 2312 are spaced apart in the circumferential direction. The rod 241 includes a sliding portion 2411, a connecting portion 2412, and a sliding block 2413 disposed on the sliding portion 2411. The connecting portion 2412 is connected to the sliding portion 2411 and the second mating portion 242. The sliding block 2413 is inserted into the chutes 231 and located at the first end 2311. It is understood that in both the first and second states, the portion of the sliding block 2413 located within the chute 231 is located at the first end position 2311. In the third state, the second engaging portion 242 is able to move along the axial direction of the switching element 23 in a direction away from the spray head 22 under the pushing action of the first engaging portion 112, thereby driving the sliding block 2413 to move along the axial direction of the switching element 23 in a direction from the first end position 2311 to the second end position 2312. Because the first end position 2311 and the second end position 2312 are spaced apart in the circumferential direction, when the sliding block 2413 slides from the first end position 2311 to the second end position 2312, it exerts a force on the switching element 23 to rotate about its axis relative to the frame 25, thereby driving at least a portion of the spray head 22 to rotate about its axis relative to the housing 21, thereby achieving the switching of the water pattern. It can be seen that the design of the switching element 23 can convert the linear motion of the rod 24 into rotational motion to achieve the switching of the water type, which is conducive to simplifying the structure of the driving and transmission mechanisms such as the driving element 12 and the rod 24, and reducing the design difficulty and preparation cost of the spray gun system 10.

[0045] In some embodiments, the second end 2312 of any chute 231 corresponds to the first end 2311 of another adjacent chute 231 in the circumferential direction of the switching element 23. In other words, the direction in which the second end surface 1122 of any chute 231 points toward the first end 2311 of another adjacent chute 231 is parallel to the axial direction of the switching element 23. The switching element 23 is further provided with a plurality of reset grooves 2313, the number of which is equal to the number of chute grooves 231. Each reset groove 2313 is located between two adjacent chute grooves 231 and communicates with the second end 2312 of one chute 231 and the first end 2311 of the other adjacent chute 231. Thus, when the first matching portion 112 pushes the second matching portion 242, driving the sliding block 2413 to slide from the first end position 2311 of one of the chutes 231 to the second end position 2312 to switch the water flow type, the sliding block 2413 can slide from the second end position 2312 through the reset groove 2313 to the first end position 2311 of the adjacent chutes 231, thereby resetting the sliding block 2413. After the sliding block 2413 is reset to the first end position 2311 of the adjacent chutes 231, the sliding block 2413 can slide along the chutes 231 from the first end position 2311 to the second end position 2312 to switch to the next water flow type. Thus, the sliding block 2413 can pass through multiple chutes 231 in sequence to switch between multiple different water flow types.

[0046] In some embodiments, the spray gun 20 also includes an elastic reset element 26, which includes but is not limited to any suitable elastic element such as a spring and rubber. The two ends of the elastic reset element 26 are respectively abutted against the rod 24 and the frame 25. When the first mating portion 112 pushes the second mating portion 242 to move relative to the shell 21, that is, when the rod 24 moves relative to the frame 25 in a direction away from the nozzle 22, the rod 24 and the frame 25 can squeeze the elastic reset element 26, so that the elastic reset element 26 is elastically compressed. Therefore, after the sliding block 2413 moves to the second end position 2312 to realize the switching of the water type, when the driving element 12 stops driving the spray gun 20 to move relative to the bracket 11, that is, the first matching part 112 stops applying force to the second matching part 242, the elastic recovery force of the elastic reset element 26 can drive the rod 24 to move toward the direction close to the nozzle 22, so as to drive the sliding block 2413 to slide along the second end position 2312 through the reset groove 2313 to the first end position 2311 of the next slide groove 231, thereby realizing the reset of the rod 24.

[0047] In some embodiments, the frame 25 includes a frame portion 251, an abutting portion 252, and an end portion 253. The end portion 253 and the abutting portion 252 are spaced apart on the frame portion 251. The switching element 23 is rotatably mounted on the end portion 253. The sliding portion 2411 is slidably inserted into the end portion 253. The connecting portion 2412 is slidably inserted into the abutting portion 252. The second mating portion 242 is located on a side of the abutting portion 252 facing away from the end portion 253. The elastic reset element 26 is sleeved on the connecting portion 2412, and the two ends of the elastic reset element 26 respectively abut against the sliding portion 2411 and the abutting portion 252. It can be understood that in the process of the first matching portion 112 pushing the second matching portion 242 to move relative to the shell 21, the sliding portion 2411 compresses the elastic reset element 26 in the direction close to the abutment portion 252, and when the first matching portion 112 stops applying force to the second matching portion 242, the elastic force of the elastic reset element 26 can drive the sliding portion 2411 to move in the direction away from the abutment portion 252, thereby realizing the reset of the rod 24 relative to the switching element 23.

[0048] Further, combined with Figure 4 、 Figure 5 and Figure 6 As shown, in some embodiments, the spray gun 20 further includes a limit seat 27, which is disposed on the frame portion 251 and opposite to the switching element 23. The limit seat 27 is provided with a limit groove 271 parallel to the axial direction of the switching element 23. The sliding block 2413 passes through the limit seat 27 and is inserted into the slide groove 231. The sliding block 2413 is slidably disposed in the limit groove 271. The provision of the limit groove 271 can provide a limit and protection function for the switching element 23, and can also provide a limit function for the sliding of the rod 24 relative to the frame 25, thereby improving the stability of the performance of the spray gun 20.

[0049] The specific structure of the nozzle 22 is not limited, as long as at least the portion of the nozzle 22 connected to the switching element 23 can rotate relative to the housing 21 along with the switching element 23 to achieve the switching of the water type of the spray gun 20. Figure 7 、 Figure 8 and Figure 9As shown, in some embodiments, the spray head 22 includes a spray structure 221 and a rotating structure 222. The spray structure 221 is fixedly disposed within the housing 21 and has at least two first water outlets 2211, each of which has different water types. The housing 21 is provided with at least two water outlets 211, which are arranged in a one-to-one correspondence with the first water outlets 2211. The rotating structure 222 is connected to and coaxially disposed with the switching element 23 and is capable of rotating relative to the spray structure 221. When the switching element 23 rotates relative to the housing 21 under the drive of the rod 24, it drives the rotating structure 222 to rotate relative to the spray structure 221. The rotation of the rotating structure 222 relative to the spray structure 221 changes the first water outlet 2211 on the spray structure 221 from which cleaning water is sprayed, thereby changing the water outlet 211 in the spray gun 20 from which cleaning water is sprayed, allowing the spray gun 20 to spray cleaning water of different types for the user.

[0050] For example, in some embodiments, the spray structure 221 is provided with at least two first water inlets 2212 on the side facing the rotating structure 222, and the first water inlets 2212 are connected to the first water outlets 2211 in a one-to-one correspondence. The spray structure 221 may be provided with multiple channels, each of which connects one of the first water inlets 2212 and the first water outlets 2211. The shape and path of the channels are not limited, as long as they can connect the corresponding first water inlets 2212 and first water outlets 2211 in a one-to-one correspondence. The rotating structure 222 is provided with a second water outlet 2221 facing the spray structure 221, and the rotating structure 222 can rotate about the axis so that the second water outlet 2221 is opposite to any of the first water inlets 2212. It can be understood that when the switching element 23 drives the rotating structure 222 to rotate around the axis, the circumferential position of the second water outlet 2221 can be changed, thereby changing the first water inlet 2212 opposite to the second water outlet 2221. The water flowing out of the second water outlet 2221 can flow into the channel of the injection structure 221 through the first water inlet 2212 opposite to the second water outlet 2221, and then be sprayed out from the corresponding first water outlet 2211. The water type of the cleaning water sprayed from different first water outlets 2211 is different, thereby realizing the switching of the water type of the outlet.

[0051] In some embodiments, the switching element 23 is provided with a connecting shaft 2314 that passes through the end portion 253 and is inserted into the rotating structure 222. The connecting shaft 2314 is fixedly connected to the rotating structure 222 so that the switching element 23 can drive the rotating structure 222 to rotate relative to the housing 21. Of course, the cooperation between the switching element 23 and the rotating structure 222 is not limited to the description of this application. The connection between the switching element 23 and the rotating structure 222 can also have any other applicable configuration, or transmission can be achieved through other intermediate elements, as long as the rotation of the switching element 23 relative to the housing 21 can drive the rotating structure 222 to rotate relative to the injection structure 221.

[0052] In some embodiments, the rotating structure 222 is further provided with a second water inlet 2222 connected to the second water outlet 2221. The spray head 22 may further include a cover 223 connected to the spray structure 221. The cover 223 is disposed on one end of the spray structure 221. The rotating structure 222 is rotatably disposed on the cover 223 and is located between the cover 223 and the spray structure 221. The spray structure 221 is provided with a water inlet 2231, which is connected to the second water inlet 2222. The spray gun 20 also includes a water inlet pipe 28 sleeved on the water inlet 2231. The water inlet pipe 28 is used to connect to an external water source. For example, when the spray gun system 10 is used on a toilet, the water inlet pipe 28 is connected to the toilet's water tank or liquid storage tank. It can be understood that when the spray gun 20 is performing a spraying operation, water from an external water source enters the spray gun 20 from the water inlet pipe 28, and passes through the water inlet 2231, the second water inlet 2222, the second water outlet 2221, the first water inlet 2212, the first water outlet 2211 and the water outlet 211 in sequence to be sprayed out from the spray gun 20.

[0053] It should be noted that, in the present application, different water jet patterns can be understood as different areas and / or shapes of the cross-section of the water jet, and the different water outlet patterns can be achieved by setting different shapes and / or sizes of the first water outlets 2211. The number of first water outlets 2211 is not limited, and can be specifically set according to the number of water outlet patterns required. It is understandable that the number of first water inlets 2212 can be the same as the number of first water outlets 2211, and the number of first water inlets 2212 can also be more than the first water outlets 2211. For example, if two or more first water inlets 2212 are connected to one of the first water outlets 2211, then the number of second water outlets 2221 can also be two or more. When water needs to be sprayed from the first water outlets 2211 corresponding to the multiple first water inlets 2212, the second water outlets 2221 are aligned with the first water inlets 2212 corresponding to the first water outlets 2211. Water flowing out of the rotating structure 222 is collected from the multiple first water inlets 2212 and sprayed out from the first water outlet 2211, thereby increasing the water volume and cross-sectional area of ​​the sprayed water corresponding to the first water outlet 2211. In some embodiments, the number of chutes 231 can be equal to the number of first water outlets 2211, and the sliding block 2413 can slide sequentially from the first end 2311 to the second end 2312 of the multiple chutes 231, thereby achieving switching between different water outlet types.

[0054] Combine Figure 2 and Figure 10 As shown, in some embodiments, the spray gun system 10 further includes a transmission element 13 and a timing belt 14. The transmission element 13 includes, but is not limited to, a gear, and the timing belt 14 includes, but is not limited to, a gear belt. The timing belt 14 cooperates with the transmission element 13 in transmission, for example, the timing belt 14 meshes with the transmission element 13. The body 111 is provided with a slide rail 1111, and the spray gun 20 is slidably disposed on the slide rail 1111. For example, the frame 25 may further include a slider portion 254 connected to the frame portion 251 and located outside the housing 21, and the slider portion 254 is slidably disposed on the slide rail 1111. The timing belt 14 is connected to the spray gun 20, for example, the slider portion 254 is partially inserted into the end of the timing belt 14. The transmission element 13 is connected to the output shaft 121 of the drive element 12, for example, the output shaft 121 of the drive element 12 is inserted into the transmission element 13. The drive element 12 may include, but is not limited to, an electric motor. The main body 111 may further include a sliding groove 1112. A portion of the sliding groove 1112 corresponds to the slide rail 1111, and the timing belt 14 is slidably disposed within the sliding groove 1112. When the driving element 12 is in operation, that is, when the output shaft 121 rotates relative to the bracket 11, it can drive the transmission element 13 to rotate relative to the bracket 11, thereby driving the timing belt 14 to slide along the sliding groove 1112, thereby driving the spray gun 20 to slide along the slide rail 1111, thereby driving the spray gun 20 to switch between the first state, the second state, and the third state.

[0055] Of course, the transmission mechanism between the drive element 12 and the spray gun 20 is not limited to the description of this application. As long as the drive element 12 can drive the spray gun 20 to move relative to the bracket 11 until the first matching portion 112 applies a force to the second matching portion 242 to drive the second matching portion 242 to move relative to the housing 21, thereby achieving the switching of the water type. In some embodiments, the spray gun system 10 may also include a position sensor (not shown) provided on the main body 111. The position sensor may be provided at the position corresponding to the spray gun 20 being in the first state and / or the second state to sense whether the spray gun 20 has reached the first state and / or the second state. The position sensor includes but is not limited to any applicable contact sensor or non-contact sensor. The spray gun system 10 may also include other components to achieve more functions. The above components may also be replaced by other components to achieve corresponding functions, which will not be described in detail in this application.
