[0018] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0019] refer to Figure 1In some specific embodiments of the present invention, a spray gun 1000 is provided, which can supply water flow (the dotted line with an arrow is a schematic representation of the water flow) to enter and then spray toward the user, so that the user can rinse and clean after defecation. The spray gun 1000 can be installed on the toilet cover of the smart toilet and move through a telescopic drive mechanism. When it is needed, it can be driven to extend and output water flow. After use, it can be retracted into the toilet cover and hidden.

[0020] refer to Figure 1 and Figure 2 In some embodiments of the present invention, the spray gun 1000 at least includes a spray head 100, a gun body 200, a flow regulating assembly 300, a first driving mechanism 400 and a second driving mechanism 500, wherein the spray head 100 is arranged on the gun body 200, and the water flow can enter the spray head 100 through the gun body 200 and output to the user. The flow regulating assembly 300 can be used to adjust the flow of water entering different flow channels of the spray head 100 to change the water output and the impact force of the water flow to meet the different cleaning needs of the user. The first driving mechanism 400 is connected to the flow regulating assembly 300, and is used to drive the flow regulating assembly 300 to adjust the flow. The second driving mechanism 500 is connected to the gun body 200. When the second driving mechanism 500 moves, it can drive the gun body 200 to expand and contract, thereby exposing the spray head 100 to water or hiding it after stopping the water, so as to prevent the spray head 100 from being exposed to the outside air and being contaminated or damaged.

[0021] It is worth noting that the "flow regulation" described in the present application includes both the situation of adjusting the size of the water flow in different flow channels and the situation of adjusting the water flow in one or more flow channels to 0, that is, at this time there is no water flowing through the flow channel.

[0022] refer to Figure 1-8 In some embodiments of the present invention, the nozzle 100 is disposed on the gun body 200. The nozzle 100 may be formed in one piece, or may be formed by assembling a plurality of different components, such as an upper shell 110, a main shell 120, and a lower shell 130. The nozzle 100 includes a first flow channel 121, a first flow cavity 123, and a first water outlet 111 that are connected in sequence, wherein the first flow channel 121 and the first flow cavity 123 are connected through a first water inlet 141, and water can enter the first flow cavity 123 from the first flow channel 121 and then be sprayed out from the first water outlet 111. A second flow channel 122 is also provided in the nozzle 100, and the second flow channel 122 is connected to the first flow chamber 123 through the second water inlet 142. Water can also enter the first flow chamber 123 from the second flow channel 122. Among them, in the range between the second water inlet 142 and the first water outlet 111, the side walls on the left and right sides of the first flow chamber 123 gradually shrink toward the first water outlet 111, showing a gradually shrinking and inclined shape.

[0023] The flow regulating component 300 is connected to the first flow channel 121 and the second flow channel 122 at the same time to regulate the flow of the first flow channel 121 and / or the second flow channel 122. Specifically, the flow regulating component 300 can be directly connected to the first flow channel 121 and the second flow channel 122, or it can be connected through a connector such as a hose. It is understandable that the flow regulating component 300 can not only regulate the flow of any one of the first flow channel 121 and the second flow channel 122 separately, but also regulate the flow of the first flow channel 121 and the second flow channel 122 at the same time, and can also make the flow change ratios of the first flow channel 121 and the second flow channel 122 different from each other when regulating the flow of the first flow channel 121 and the second flow channel 122 at the same time.

[0024] An oscillation unit 140 is disposed in the first flow chamber 123. The oscillation unit 140 includes two guides 143. The two guides 143 may be protrusions protruding from the bottom wall of the oscillation unit 140. The two guides 143 are spaced apart in the first flow chamber 123 and are symmetrical to each other about the symmetry line, and are mirror images of each other, with the line between the first water inlet 141 and the first water outlet 111 as the symmetry line. A main flow channel 144 is formed between the two guides 143. One end of the main flow channel 144 is connected to the first flow channel 121 through the first water inlet 141, and the other end is connected to the first water outlet 111. Specifically, the width of the main flow channel 144 gradually increases along the water inlet direction of the first flow channel 121. The two guide portions 143 are disposed on the inner walls of the first flow chamber 123 and are spaced apart from the wall to form two feedback channels 145. The two feedback channels 145 are roughly C-shaped and are located on both sides of the main channel 144, respectively. The two ends of the feedback channels 145 are connected to the two ends of the main channel 144, respectively. The second water inlet 142 is disposed on one end of the main channel 144 close to the first water outlet 111.

[0025] It can be understood that the oscillation unit 140 can be formed integrally with the nozzle 100, or it can be a separately arranged oscillation unit 140, the two guide parts 143, the first water inlet 141 and the second water inlet 142 are all arranged on the oscillation unit 140, the oscillation unit 140 can be inserted into and fixed in the first flow cavity 123, and the first water inlet 141 is connected to the first flow channel 121, the second water inlet 142 is connected to the second flow channel 122, and one end of the main flow channel 144 is connected to the first water outlet 111.

[0026] The following is an example of different water discharge processes of the spray gun 1000 provided in the embodiment of the present invention: When the flow regulating assembly 300 is adjusted to allow only the first flow channel 121 to flow in, the water flows from the first flow channel 121 through the first water inlet 141 and flows to the main flow channel 144. Due to the Coanda effect, the water flows along the side flow channel of the guide portion 143 close to the main flow channel 144. When the water flows into the main flow channel 144, it is random which side of the guide portion 143 the water flows along. Assuming that the water flows along the right side of the guide portion 143 first (e.g. Fig.11 ), the water will flow along the side to one end of the right feedback channel 145, and then a part of the water will enter the feedback channel 145 and return to the end of the main channel 144 close to the first water inlet 141, and the other part of the water will flow out from the first water outlet 111 along the right side wall of the first flow cavity 123. When the water flow of the right feedback channel 145 enters the main channel 144, it will merge with the subsequent water flow entering the main channel 144 through the first water inlet 141 and push it to deviate to the left, so that it flows along the side of the left guide part 143 to one end of the left feedback channel 145 (such as Fig.12 ), at this time, part of the water flows out from the first water outlet 111 along the side wall of the left side of the first flow cavity 123, while the other part of the water flows back to the main channel 144 through the feedback channel 145 and pushes the subsequent water inflow to deviate to the right, thereby changing the water outlet direction again and changing it periodically. In this process, the water flow will quickly sweep back and forth in the left and right directions. Visually, the water outlet shape of the first water outlet 111 is fan-shaped (such as Fig.13 ).

[0027] When the flow regulating assembly 300 is adjusted to the point where only the second flow channel 122 enters water, the water flows into the first flow cavity 123 from the second water inlet 142. Since the second water inlet 142 is disposed at one end of the main flow channel 144 close to the first water outlet 111, the Coanda effect is relatively weak, and even if a small amount of water flows into the feedback flow channel 145, it will not affect the water inflow of the second water inlet 142 at this position. At this time, the water flows directly out of the first water outlet 111, and visually the water outlet shape of the first water outlet 111 is cylindrical (e.g., Fig. 9 , Fig.10 ).

[0028] When the flow regulating component 300 is adjusted to the point where water enters both the first flow channel 121 and the second flow channel 122, the water entering through the first flow channel 121 will still be sprayed out obliquely through the first water outlet 111, which is defined as the first water flow, and will be repeatedly swept to form a fan-shaped water outlet. However, at this time, the water entering the second flow channel 122 will also spray out columnar water outlet upwards, which is defined as the second water flow. Therefore, the water columns in two directions collide and merge at the first water outlet, which will make the angle of the merged water flow still oblique, and the water outlet shape still fan-shaped, but due to the influence of the second water flow, the fan-shaped angle of the merged water flow is smaller than the fan-shaped water outlet angle when only the first flow channel 121 enters water. And the angle of the merged fan-shaped water flow will change with the ratio between the first water flow and the second water flow. For example, when the flow rate of the first water flow is large, the fan-shaped angle is larger (but still smaller than the fan-shaped angle when the first water flow is discharged alone), and when the flow rate of the second water flow is large, the fan-shaped angle becomes smaller (but still fan-shaped, and will not be discharged in a columnar shape). Therefore, the user can arbitrarily adjust the ratio between the first water flow and the second water flow through the flow regulating component 300, thereby adjusting the angle of the fan-shaped water outlet, and can perform stepless adjustment according to different usage requirements of the user.

[0029] According to the spray gun 1000 provided in the embodiment of the present invention, the user can control the flow regulating component 300 according to the demand, and independently control the water inlet of the first flow channel 121 to make the spray gun 1000 output fan-shaped water, or independently control the water inlet of the second flow channel 122 to make the spray gun 1000 output columnar water. It is also possible to control the water inlet of the first flow channel 121 and the second flow channel 122 at the same time, and steplessly adjust the flow of the first flow channel 121 or the second flow channel 122 to change the water inlet ratio between the two, thereby changing the angle of the fan-shaped water outlet. Therefore, the spray gun 1000 of the embodiment of the present invention can output a variety of different water outlet types through one water outlet hole, so as to meet the diverse cleaning needs of users, with convenient adjustment and good user experience. In addition, there is no need to set multiple water outlet holes and water outlet channels for different water outlet types, which is conducive to the miniaturization of the nozzle 100 and the spray gun 1000, and saves the volume occupied in the smart toilet cover.

[0030] It is understandable that the flow regulating component 300 is not limited to controlling the first flow channel 121 and the second flow channel 122, and can also simultaneously control the flow channels corresponding to other water outlet functions in the spray gun 1000, and the flow regulating component 300 can be set in a variety of ways, such as the flow regulating component 300 includes a plurality of flow regulating switches, such as a gate valve switch, a ball valve switch, etc., each switch controls a different flow channel, and each switch is controlled by the user. Among them, one or more mechanical control switches can be set in the smart toilet cover for the user to control the flow regulating component 300, and a control module and one or more driving devices electrically connected to the control module, such as a motor, can be set in the smart toilet cover, and each flow regulating switch is connected to the motor. When the user inputs control information through a button or a display screen, the control module controls the motor to operate, and the motor controls the target regulating switch to operate to achieve the regulation purpose.

[0031] refer to Fig.14 In some embodiments of the present invention, the flow regulating assembly 300 includes a static valve plate 320 and a movable valve plate 310. The flow regulating assembly 300 is controlled by a first driving mechanism 400. Specifically, the first driving mechanism 400 is a motor, and the driving shaft of the motor is connected to the movable valve plate 310. When the motor rotates, the movable valve plate 310 is driven to rotate to change the water flow cross-sectional area between the movable valve plate 310 and the static valve plate 320.

[0032] Specifically, the static valve plate 320 is provided with a first water passage 321 and a second water passage 322, wherein one of the first water passage 321 and the second water passage 322 is communicated with the first flow channel 121, and the other is communicated with the second flow channel 122. The movable valve plate 310 is arranged concentrically with the static valve plate 320, and is provided with a first water passage hole 311 and a second water passage hole 312 in the water inlet direction, wherein the first water passage hole 311 is arranged corresponding to the first water passage 321, and the second water passage hole 312 is arranged corresponding to the second water passage 322. Specifically, the distance between the first water hole 311 and the center of the movable valve plate 310 is equal to the distance between the first water channel 321 and the center of the static valve plate 320, and the distance between the second water hole 312 and the center of the movable valve plate 310 is equal to the distance between the second water channel 322 and the center of the static valve plate 320. In addition, with the water inlet direction as the rotation axis, the movable valve plate 310 can rotate relative to the static valve plate 320 along the first direction or the second direction. When the movable valve plate 310 rotates, the water cross-sectional area connected between the first water hole 311 and the first water channel 321, and / or the water cross-sectional area connected between the second water hole 312 and the second water channel 322 changes, thereby adjusting the flow rate entering the first flow channel 121 and the second flow channel 122.

[0033] It is understandable that the counterclockwise direction can be defined as the first direction and the clockwise direction can be defined as the second direction, or the clockwise direction can be defined as the first direction and the counterclockwise direction can be defined as the second direction. In this case, the adjustment effects of the two different direction definition methods are opposite.

[0034] Further, in the rotation direction of the movable valve plate 310, the water flow cross-sections of the first water flow channel 321 and the second water flow channel 322 can be set in a variety of ways. For example, the water flow areas of the first water flow channel 321 and the second water flow channel 322 are the same. When the movable valve plate 310 rotates within a certain angle range, the flow cross-sectional areas of the first water flow channel 321 and the second water flow channel 322 are adjusted and changed at the same time. When rotated to a specific angle range, both water flow channels are closed; for another example, the water flow areas of the first water flow channel 321 and the second water flow channel 322 are different. Therefore, when the movable valve plate 310 rotates to a specific angle range, one of the water flow holes has been separated from the corresponding water flow channel. At this time, the flow channel corresponding to the water flow channel is closed, and the other water flow hole is still rotating within the range of the other water flow channel. At this time, the flow channel corresponding to the water flow channel still has water flowing and the flow rate of the flow channel can continue to be adjusted.

[0035] refer to Fig.14 In some specific embodiments of the present invention, the first water passage 321 extends along the rotation direction of the first water hole 311. At this time, the first water passage 321 is in the shape of a long groove. The first water passage 321 includes a first water groove 3211 and a first water outlet 3212 connected to each other. The first water outlet 3212 is connected to the first flow channel 121 or the second flow channel 122. After the water flows through the first water hole 311, it enters the first water groove 3211 and then flows into the connected flow channel through the first water outlet 3212. When the movable valve plate 310 and the static valve plate 320 are attached, the first water groove 3211 is closed on the side close to the movable valve plate 310. Among them, the bottom wall of the first water flow groove 3211 gradually increases along the first direction. Therefore, in the water inlet direction of the first water flow hole 311, the water flow cross-sectional area of ​​the first water flow channel 321 gradually decreases. Therefore, when the first water flow hole 311 rotates along the first direction, the water flow cross-sectional area gradually decreases. At this time, the flow rate passing through the first water flow channel 321 also gradually decreases, thereby achieving the purpose of flow regulation.

[0036] At this time, the water flow cross-sectional area of ​​the second water flow channel 322 may remain unchanged, and the flow regulating device only changes the flow of one of the flow channels, thereby adjusting the water outlet angle of the fan-shaped water outlet.

[0037] It is understandable that the first water passage 321 can be arranged in a variety of ways, as long as its water flow cross-sectional area can be changed during the rotation of the movable valve plate 310. For example, the bottom wall height of the first water passage 3211 remains unchanged, but its cross-sectional width along the plane where the static valve plate 320 is located gradually decreases along the first direction. At this time, when the first water passage 311 rotates to different positions, the water flow cross-sectional area will also change, and the purpose of flow regulation can also be achieved.

[0038] It can be understood that the cross-sectional width of the first water flow channel 3211 along the plane where the static valve plate 320 is located gradually decreases along the first direction, and the bottom wall height also gradually increases along the first direction. At this time, the change in the water flow cross-section is more significant, and the flow regulation effect is more obvious.

[0039] In some embodiments of the present invention, the second water passage 322 extends along the rotation direction of the second water hole 312. At this time, the second water passage 322 is in the shape of a long groove. The second water passage 322 includes a second water groove 3221 and a second water outlet 3222 connected to each other. After the water flows through the second water hole 312, it enters the second water groove 3221 and then flows into the connected flow channel through the second water outlet 3222. When the movable valve plate 310 and the static valve plate 320 are attached, the side of the second water groove 3221 close to the movable valve plate 310 is closed, and the bottom wall of the second water groove 3221 gradually increases along the second direction. Therefore, in the water inlet direction of the second water hole 312, the water flow cross-sectional area of ​​the second water passage 322 gradually decreases. Therefore, when the second water hole 312 rotates along the second direction, the water flow cross-sectional area gradually decreases, and the flow through the second water passage 322 also gradually decreases, thereby achieving the purpose of flow regulation.

[0040] At this time, the water flow cross-sectional area of ​​the first water flow channel 321 may be constant, and the flow regulating device only changes the flow of one of the flow channels, thereby adjusting the water outlet angle of the fan-shaped water outlet.

[0041] It is understandable that the second water passage 322 can be arranged in a variety of ways, as long as its water flow cross-sectional area can be changed during the rotation of the movable valve plate 310. For example, the bottom wall height of the second water passage 3221 remains unchanged, but its cross-sectional width along the plane where the static valve plate 320 is located gradually decreases along the second direction. At this time, when the second water passage hole 312 rotates to different positions, the water flow cross-sectional area will also change, and the purpose of flow regulation can also be achieved.

[0042] It can be understood that the cross-sectional width of the second water flow channel 3221 along the plane where the static valve plate 320 is located gradually decreases along the second direction, and the bottom wall height also gradually increases along the second direction. At this time, the change in the water flow cross-section is more significant, and the flow regulation effect is more obvious.

[0043] In some specific embodiments of the present invention, along the first direction, the bottom wall height of the first water channel 3211 gradually increases and / or its cross-sectional width along the plane where the static valve plate 320 is located gradually decreases, and, along the second direction, the bottom wall height of the first water channel 3211 gradually increases and / or its cross-sectional width along the plane where the static valve plate 320 is located gradually decreases. At this time, no matter whether the movable valve plate 310 rotates along the first direction or the second direction, the flow in the first flow channel 121 and the second flow channel 122 can be changed, and the flow in one flow channel is always increased, and the flow in the other flow channel is reduced, thereby changing the flow ratio between the two flow channels, and then changing the angle of the fan-shaped water outlet.

[0044] refer to Fig.15 , taking the case where the flow regulating component 300 can only change the flow of the first flow channel 121 (such as the bottom wall height of the first water channel 3211 gradually increases and / or the cross-sectional width thereof along the plane where the static valve plate 320 is located gradually decreases), and the flow of the second flow channel 122 remains unchanged (such as the bottom wall height of the second water channel 3221 remains unchanged, and the cross-sectional width thereof along the plane where the static valve plate 320 is located remains unchanged) as an example, the flow regulating process of the embodiment of the present invention is described: When the movable valve plate 310 rotates to position 1, the water flow cross-sectional area of ​​the first water flow channel 321 is 0 or the water flow cross-sectional area is extremely small, the flow rate of the first flow channel 121 is 0 or extremely small, and the flow rate of the second flow channel 122 remains unchanged. At this time, the shape of the water outlet of the second flow channel 122 is not affected or is only affected by a very small amount of water flow entering from the first flow channel 121. At this time, the water type output by the nozzle 100 is columnar water; when the movable valve plate 310 rotates to position 2, the water flow cross-sectional area of ​​the first water flow channel 321 is the largest, the flow rate of the first flow channel 121 also reaches the maximum, and the flow rate of the second flow channel 122 remains unchanged. When the movable valve plate 310 rotates to position 3, the water flow cross-sectional area of ​​the first water passage 321 is between 0 and the maximum, and the flow rate of the second flow channel 122 remains unchanged. At this time, the water flow of the first flow channel 121 and the water flow of the second flow channel 122 both have an impact on the water outlet angle. Therefore, at this time, the water type output by the nozzle 100 is fan-shaped water, but the fan-shaped angle is smaller than the fan-shaped water outlet angle when the movable valve plate 310 is in position 2.

[0045] The first water passage 321 and the second water passage 322 have been described in various configurations, and the flow rate and water type adjustment principles are the same, which will not be described again.

[0046] Therefore, the user can control the movable valve plate 310 to rotate to different positions through a mechanical or electronic control module, thereby achieving stepless adjustment of the fan-shaped water outlet angle.

[0047] refer to Figure 5In some specific embodiments of the present invention, at least one strip groove 1231 is provided on the side wall of the first flow cavity 123, one end of the strip groove 1231 is connected to the first water outlet 111, and the other end extends in a direction close to the second water inlet 142. Therefore, when water flows into the second water inlet 142 and flows out of the first water outlet 111, the strip groove 1231 can guide the water column, thereby making the water column straighter and avoiding the water column from spreading and splashing.

[0048] Specifically, two strip-shaped grooves 1231 are provided and are symmetrical about two sides of the outlet water column, thereby forming a guide channel for the water column.

[0049] refer to Figure 4 and Figure 5 In some embodiments of the present invention, two first guide posts 146 are arranged between the first water outlet 111 and the second water inlet 142, and the two first guide posts 146 are symmetrically arranged about the line between the first water outlet 111 and the second water inlet 142. It can be understood that the two first guide posts 146 divide the channel between the second water inlet 142 and the first water outlet 111 into three small channels, wherein the small channels on the left and right sides can guide the water entering from the side wall of the guide portion 143 to flow to the left and right side walls of the first flow chamber 123, thereby ensuring that the water flow can be sprayed out along the side wall at a certain angle, and the small channel in the middle can guide and limit the water flow entering the second flow channel 122, so that it always flows upward, avoiding mixing with the water flow entering from the side wall of the guide portion 143 in the first flow chamber 123, and failing to achieve fan-shaped water outlet angle adjustment.

[0050] refer to Figure 6-8 In some specific embodiments of the present invention, the nozzle 100 further includes a third flow channel 124, a second flow chamber 125, a second water outlet 126, an air suction chamber 127 and a third water outlet 112 which are connected in sequence, wherein a second guide column 131 is provided in the second flow chamber 125, the second water outlet 126 is exposed in the air suction chamber 127, and in the direction of water outflow, the second water outlet 126 and the third water outlet 112 are correspondingly arranged, the water flowing out of the second water outlet 126 can pass through the air suction chamber 127 and then flow out from the third water outlet 112, and the air suction chamber 127 is provided with an air suction hole connected to the outside, when the water flows through the second water outlet 126 and is accelerated to be ejected, due to the Venturi principle, a negative pressure area is formed near the second water outlet 126, and the outside air enters the air suction chamber 127 through the air suction hole and forms bubble water after mixing with the water flow, and the bubble water is ejected through the third water outlet 112.
