[0049] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numbers represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0050] Reference Figure 1 In some embodiments of the present application, a spray gun 1000 is provided, which can be used for water flow (the water flow is indicated by the arrowed dashed line) to enter and spray towards the user, so that the user can clean after use. The spray gun 1000 can be installed on the toilet cover plate of the intelligent toilet, and moved by the telescopic driving mechanism. When needed, it can be driven to extend and output water flow, and after use, it can be retracted to hide in the toilet cover plate.

[0051] Reference Figure 1 And Figure 2 In some embodiments of the present application, 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. 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 in different flow channels of the spray head 100 to change the water output and water flow impact force, so as to meet the different cleaning needs of the user. The first driving mechanism 400 is connected with the flow regulating assembly 300, and is used to drive the flow regulating assembly 300 to regulate the flow. The second driving mechanism 500 is connected with the gun body 200, and when the second driving mechanism 500 moves, it can drive the gun body 200 to extend and retract, so as to make the spray head 100 exposed to water or stop water and then hidden, avoiding the spray head 100 being polluted or damaged by being exposed to the outside air all the time.

[0052] It is worth noting that the "flow regulation" described in the present application includes both the case of adjusting the size of the water flow in different flow channels and the case of adjusting the water flow in one or more flow channels to 0, i.e. at this time the flow channel no longer has water flow through.

[0053] Reference Figures 1-8 In some embodiments of the present application, the spray head 100 is arranged on the gun body 200. The spray head 100 can be integrally formed or can be formed by assembling a plurality of different components, such as the upper shell 110, the main shell 120 and the lower shell 130. The spray head 100 includes a first flow channel 121, a first flow cavity 123 and a first water outlet 111 which are sequentially connected. The first flow channel 121 and the first flow cavity 123 are connected through a first water inlet 141, and the water flow can enter the first flow cavity 123 from the first flow channel 121 and then be sprayed from the first water outlet 111. The spray head 100 further includes a second flow channel 122 which is connected with the first flow cavity 123 through a second water inlet 142. The water flow can also enter the first flow cavity 123 from the second flow channel 122. 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 cavity 123 gradually shrink towards the first water outlet 111, forming a gradually shrinking and inclined shape.

[0054] The flow regulation assembly 300 is connected with the first flow channel 121 and the second flow channel 122 to regulate the flow of the first flow channel 121 and / or the second flow channel 122. Specifically, the flow regulation assembly 300 can be directly connected with the first flow channel 121 and the second flow channel 122, or can be connected through a hose or other connecting member. It can be understood that the flow regulation assembly 300 can adjust the flow of any one of the first flow channel 121 and the second flow channel 122, can simultaneously adjust the flow of the first flow channel 121 and the second flow channel 122, or can adjust the flow of the first flow channel 121 and the second flow channel 122 while making the flow change ratio of the first flow channel 121 and the second flow channel 122 different from each other.

[0055] The oscillation unit 140 is arranged in the first flow cavity 123, and the oscillation unit 140 comprises two flow guide portions 143. The two flow guide portions 143 can be protruding blocks arranged on a bottom wall of the oscillation unit 140. The two flow guide portions 143 are arranged in the first flow cavity 123 in a symmetrical manner with respect to a symmetrical line between the first water inlet 141 and the first water outlet hole 111. The two flow guide portions 143 are arranged in a symmetrical manner with respect to the symmetrical line and are mirror images of each other. The two flow guide portions 143 form a main flow channel 144 therebetween. One end of the main flow channel 144 is in communication with the first flow channel 121 through the first water inlet 141, and the other end of the main flow channel 144 is in communication with the first water outlet hole 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 flow guide portions 143 are arranged away from each other and face the inner walls of the two sides of the first flow cavity 123, and are arranged away from the walls to form two feedback flow channels 145. The two feedback flow channels 145 are substantially in the shape of a 'C' and are arranged on the two sides of the main flow channel 144, respectively. The two ends of the feedback flow channels 145 are in communication with the two ends of the main flow channel 144, respectively. The second water inlet 142 is arranged on the main flow channel 144 and is close to one end of the first water outlet hole 111.

[0056] It can be understood that the oscillation unit 140 can be formed integrally with the spray head 100, or the oscillation unit 140 can be arranged separately. The two flow guide portions 143, the first water inlet 141 and the second water inlet 142 are 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 in communication with the first flow channel 121, the second water inlet 142 is in communication with the second flow channel 122, and one end of the main flow channel 144 is in communication with the first water outlet hole 111.

[0057] The different water outlet processes of the spray gun 1000 provided in the embodiment of the utility model will be described below.

[0058] When the flow regulating assembly 300 is adjusted to allow water to flow into only the first flow channel 121, the water flows from the first flow channel 121 to the first water inlet 141 and then to the main flow channel 144. Due to the Coanda effect, the water flow will flow along the side of the flow guide portion 143 close to the main flow channel 144. When the water flow begins to enter the main flow channel 144, the water flow will flow along the side of which flow guide portion 143 is random. It is assumed that the water flow first flows along the right flow guide portion 143 (as shown in FIG. 6A). Figure 11), the water flow will flow along the side to the right end of the feedback flow channel 145, then a part of the water enters the feedback flow channel 145 and returns to the main flow channel 144 near the first water inlet 141, and the other part of the water flows out from the first water outlet hole 111 in the direction of the side wall of the right side of the first flow cavity 123. When the water flow in the right feedback flow channel 145 enters the main flow channel 144, it will converge with the subsequent water flow entering the main flow channel 144 through the first water inlet 141 and push it to the left side, so that it flows along the side of the left guide part 143 to the left end of the left feedback flow channel 145 (as shown in Figure 12 ), at this time, a part of the water flows out from the first water outlet hole 111 in the direction of the side wall of the left side of the first flow cavity 123, and the other part of the water flow returns to the main flow channel 144 through the feedback flow channel 145 and pushes the subsequent water to the right side, thereby changing the water outlet direction again, and the water flow will keep changing periodically in the left-right direction, and in the process, the water flow will quickly sweep back and forth in the left-right direction, and the water outlet shape of the first water outlet hole 111 appears fan-shaped (as shown in Figure 13 ).

[0059] When the flow regulating assembly 300 is adjusted to only the second flow channel 122, the water flow enters the first flow cavity 123 from the second water inlet 142, and since the second water inlet 142 is arranged near the first water outlet hole 111 of the main flow channel 144, the Coanda effect is relatively weak, and even if a small amount of water flow enters the feedback flow channel 145, it will not affect the water inlet of the second water inlet 142 at this position, at this time, the water flow directly flows out from the first water outlet hole 111, and the water outlet shape of the first water outlet hole 111 appears column-shaped (as shown in Figure 9 、 Figure 10 ).

[0060] When the flow regulating assembly 300 is adjusted to water entering both the first flow channel 121 and the second flow channel 122, the water flow entering through the first flow channel 121 is still inclined to spray out through the first water outlet hole 111, defined as the first water flow, and repeatedly sweeps to form a fan-shaped water outlet, but at this time the water entering the second flow channel 122 is also sprayed upward as a column-shaped water outlet, defined as the second water flow. Therefore, the water columns in two directions collide and converge at the first water outlet, and the angle of the converged water flow is still inclined, and the water outlet shape is still fan-shaped, but due to the influence of the second water flow, the fan angle of the converged water flow is smaller than the fan angle of the water outlet when only the first flow channel 121 is watered. And the angle of the converged fan-shaped water flow changes with the ratio between the first water flow and the second water flow, for example, when the first water flow is larger, the fan angle is larger (but still smaller than the fan angle when only the first water flow is watered), and when the second water flow is larger, the fan angle is smaller (but still fan-shaped, not column-shaped). Thus, the user can adjust the ratio between the first water flow and the second water flow through the flow regulating assembly 300 to adjust the angle of the fan-shaped water outlet, and can adjust it infinitely according to the user's different use requirements.

[0061] According to the spray gun 1000 provided in the embodiment of the utility model, the user can control the flow regulating assembly 300 according to the demand, control the first flow channel 121 to water alone to make the spray gun 1000 output fan-shaped water, or control the second flow channel 122 to water alone to make the spray gun 1000 output column-shaped water, or control the first flow channel 121 and the second flow channel 122 to water at the same time, and infinitely adjust the flow of the first flow channel 121 or the second flow channel 122 to change the water entering ratio between the two, so as to change the angle of the fan-shaped water outlet. Therefore, the spray gun 1000 of the embodiment of the utility model can output multiple different water types through one water outlet hole, meet the diversified cleaning needs of the user, adjust conveniently, have good use experience, and do not need to set multiple water outlet holes and water outlet channels for different water types, which is beneficial to the miniaturization of the spray head 100 and the spray gun 1000, and saves the volume occupied in the intelligent toilet cover plate.

[0062] It can be understood that the flow regulating assembly 300 is not limited to controlling the first flow channel 121 and the second flow channel 122, but can also control flow channels corresponding to other water outlet functions in the spray gun 1000 at the same time, and the flow regulating assembly 300 can be in various settings, such as the flow regulating assembly 300 comprising a plurality of flow regulating switches, such as gate valve switches, ball valve switches, etc., each switch controlling a different flow channel, and each switch being controlled by a user. Among them, one or more mechanical control switches can be provided in the intelligent toilet cover plate for the user to control the flow regulating assembly 300, and a control module and one or more driving devices electrically connected to the control module, such as motors, etc., can also be provided in the intelligent toilet cover plate, and each flow regulating switch is connected to the motor, when the user inputs control information through the key or the display screen, etc., the control module controls the motor to operate, and the motor controls the target regulating switch to operate to achieve the regulating purpose.

[0063] Reference Figure 14 In some embodiments of the present application, the flow regulating assembly 300 comprises a static valve plate 320 and a dynamic valve plate 310, and 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 with the dynamic valve plate 310, when the motor rotates, the dynamic valve plate 310 is driven to rotate to change the water passing cross-sectional area between the dynamic valve plate 310 and the static valve plate 320.

[0064] Specifically, the static valve plate 320 is provided with a first water passing channel 321 and a second water passing channel 322, wherein one of the first water passing channel 321 and the second water passing channel 322 is communicated with the first flow channel 121, and the other is communicated with the second flow channel 122. The dynamic valve plate 310 is concentrically arranged with the static valve plate 320, and is provided with a first water passing hole 311 and a second water passing hole 312 in the water inlet direction, the first water passing hole 311 is arranged corresponding to the first water passing channel 321, and the second water passing hole 312 is arranged corresponding to the second water passing channel 322. Specifically, the distance between the first water passing hole 311 and the center of the dynamic valve plate 310 is equal to the distance between the first water passing channel 321 and the center of the static valve plate 320, and the distance between the second water passing hole 312 and the center of the dynamic valve plate 310 is equal to the distance between the second water passing channel 322 and the center of the static valve plate 320, and the dynamic valve plate 310 can rotate relative to the static valve plate 320 along the first direction or the second direction with the water inlet direction as the rotation axis, when the dynamic valve plate 310 rotates, the water passing cross-sectional area between the first water passing hole 311 and the first water passing channel 321, and / or the water passing cross-sectional area between the second water passing hole 312 and the second water passing channel 322 changes, thereby regulating the flow into the first flow channel 121 and the second flow channel 122.

[0065] It can be understood 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, and the adjustment effects of the two different direction definitions are opposite.

[0066] Further, in the rotation direction of the valve disc 310, the water passing sections of the first water passing channel 321 and the second water passing channel 322 can be variously arranged, for example, the water passing areas of the first water passing channel 321 and the second water passing channel 322 are the same, when the valve disc 310 rotates within a certain angle range, the water passing sections of the first water passing channel 321 and the second water passing channel 322 are simultaneously adjusted and changed, when the valve disc 310 rotates to a certain angle range, both of the water passing channels are closed; for another example, the water passing areas of the first water passing channel 321 and the second water passing channel 322 are different, therefore, when the valve disc 310 rotates to a certain angle range, one of the water passing holes is out of the corresponding water passing channel, at this time, the flow channel corresponding to the water passing channel is closed, and the other water passing hole is still rotating within the other water passing channel, at this time, the flow channel corresponding to the water passing channel still has water flow and can continue to adjust the flow of the flow channel.

[0067] Reference Figure 14 In some specific embodiments of the utility model, the first water passing channel 321 extends along the rotation direction of the first water passing hole 311, at this time, the first water passing channel 321 is in the shape of a long groove, the first water passing channel 321 comprises a first water passing groove 3211 and a first water passing hole 3212 connected with each other, the first water passing hole 3212 is communicated with the first flow channel 121 or the second flow channel 122, after the water flow passes through the first water passing hole 311, enters the first water passing groove 3211 and then flows into the connected flow channel through the first water passing hole 3212. When the valve disc 310 is attached to the static valve disc 320, the side of the first water passing groove 3211 close to the valve disc 310 is closed. Among them, the bottom wall of the first water passing groove 3211 gradually increases along the first direction, therefore, in the water inlet direction of the first water passing hole 311, the water passing section area of the first water passing channel 321 gradually decreases, therefore, when the first water passing hole 311 rotates along the first direction, the water passing section area gradually decreases, at this time, the flow through the first water passing channel 321 also gradually decreases, thereby achieving the purpose of flow adjustment.

[0068] At this time, the water passing section area of the second water passing channel 322 can be unchanged, at this time, the flow adjustment device only changes the flow of one of the flow channels, thereby the water outlet angle of the fan-shaped water outlet.

[0069] It can be understood that the first water passage 321 can also be in various arrangements, as long as the water passage cross-sectional area can be changed during the rotation of the moving valve plate 310. For example, the first water passage 321 has a constant bottom wall height, but the cross-sectional width along the plane of the static valve plate 320 gradually decreases in the first direction. When the first water hole 311 is rotated to different positions, the water passage cross-sectional area also changes, and the flow regulation purpose can also be achieved.

[0070] It can be understood that the first water passage 321 has a constant bottom wall height, but the cross-sectional width along the plane of the static valve plate 320 gradually decreases in the first direction. When the first water hole 311 is rotated to different positions, the water passage cross-sectional area also changes, and the flow regulation purpose can also be achieved.

[0071] In some embodiments of the utility model, 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, and the second water passage 322 includes a second water passage 3221 and a second water hole 3222 connected to each other. After the water flow passes through the second water hole 312, it enters the second water passage 3221 and then flows into the connected flow channel through the second water hole 3222. When the moving valve plate 310 is attached to the static valve plate 320, the side of the second water passage 3221 close to the moving valve plate 310 is closed, and the bottom wall of the second water passage 3221 gradually increases in the second direction. Therefore, in the water inlet direction of the second water hole 312, the water passage cross-sectional area of the second water passage 322 gradually decreases, so when the second water hole 312 rotates in the second direction, the water passage cross-sectional area gradually decreases, and at this time, the flow through the second water passage 322 also gradually decreases, thereby achieving the flow regulation purpose.

[0072] At this time, the water passage cross-sectional area of the first water passage 321 can be constant, at this time, the flow regulation device only changes the flow of one of the flow channels, thereby adjusting the water outlet angle of the fan-shaped water outlet.

[0073] It can be understood that the second water passage 322 can also be in various arrangements, as long as the water passage cross-sectional area can be changed during the rotation of the moving valve plate 310. For example, the second water passage 3221 has a constant bottom wall height, but the cross-sectional width along the plane of the static valve plate 320 gradually decreases in the second direction. When the second water hole 312 is rotated to different positions, the water passage cross-sectional area also changes, and the flow regulation purpose can also be achieved.

[0074] It can be understood that the second water passage 3221 has a constant bottom wall height, but the cross-sectional width along the plane of the static valve plate 320 gradually decreases in the second direction. When the second water hole 312 is rotated to different positions, the water passage cross-sectional area also changes, and the flow regulation purpose can also be achieved.

[0075] In some specific embodiments of the utility model, along the first direction, the bottom wall height of the first water channel 3211 gradually increases and / or its cross section width along the plane of the static valve piece 320 gradually decreases, and, along the second direction, the bottom wall height of the first water channel 3211 gradually increases and / or its cross section width along the plane of the static valve piece 320 gradually decreases, at this time, no matter the dynamic valve piece 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 always increases and the flow in the other flow channel decreases, thereby changing the flow ratio between the two flow channels, and further changing the angle of the fan-shaped water outlet.

[0076] Reference Figure 15 Taking the flow regulating assembly 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 its cross section width along the plane of the static valve piece 320 gradually decreases) and the flow of the second flow channel 122 does not change (such as the bottom wall height of the second water channel 3221 does not change, and its cross section width along the plane of the static valve piece 320 also does not change) as an example, the flow regulating process of the utility model embodiment is explained:

[0077] When the dynamic valve piece 310 rotates to position 1, the water passing cross section area of the first water passing channel 321 is 0 or very small, the flow of the first flow channel 121 is 0 or very small, and the flow of the second flow channel 122 does not change, at this time, the water outlet shape of the second flow channel 122 is not affected or is only affected by a very small amount of water flow from the first flow channel 121, at this time, the output water type of the nozzle 100 is columnar water;

[0078] When the dynamic valve piece 310 rotates to position 2, the water passing cross section area of the first water passing channel 321 is maximum, the flow of the first flow channel 121 also reaches maximum, and the flow of the second flow channel 122 does not change, at this time, the water outlet shape of the second flow channel 122 is most affected by the water flow from the first flow channel 121, at this time, the output water type of the nozzle 100 is fan-shaped water, and the fan-shaped angle is maximum;

[0079] When the dynamic valve piece 310 rotates to position 3, the water passing cross section area of the first water passing channel 321 is between 0 and maximum, and the flow of the second flow channel 122 does not change, 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 influence on the water outlet angle, therefore, at this time, the output water type of the nozzle 100 is fan-shaped water, but the fan-shaped angle is smaller than the fan-shaped water outlet angle when the dynamic valve piece 310 is at position 2.

[0080] The first water passing channel 321 and the second water passing channel 322 have been described in the above, and the flow and water type regulating principles are the same, and details are not repeated here.

[0081] Therefore, the user can control the rotating of the valve disc 310 to different positions through the mechanical or electronic control module, so as to realize the stepless adjustment of the fan-shaped water outlet angle.

[0082] With reference to Figure 5 In some specific embodiments of the present application, at least one strip-shaped groove 1231 is arranged on the side wall of the first flow cavity 123, one end of the strip-shaped groove 1231 is connected with the first water outlet hole 111, and the other end extends in the direction close to the second water inlet 142. Thus, when the water flows into the second water inlet 142 and flows out of the first water outlet hole 111, the strip-shaped groove 1231 can guide the water column, so that the water column is more straight, and splashing of the water column is avoided.

[0083] Specifically, two strip-shaped grooves 1231 are arranged and symmetrical about the two sides of the water column, so as to form a guide channel of the water column.

[0084] With reference to Figure 4 And Figure 5 In some embodiments of the present application, two first flow guide columns 146 are arranged between the first water outlet hole 111 and the second water inlet 142, and the two first flow guide columns 146 are symmetrically arranged about the line connecting the first water outlet hole 111 and the second water inlet 142. It can be understood that the two first flow guide columns 146 divide the channel between the second water inlet 142 and the first water outlet hole 111 into three small channels, wherein the small channels on the left and right sides can guide the water flow entering from the side wall of the flow guide part 143 to the left and right side walls of the first flow cavity 123, so as to ensure that the water flow can be inclined at a certain angle along the side wall and sprayed out, and the small channel in the middle can guide and limit the water flow entering the second flow channel 122, so as to always ensure that the water flow flows upward, avoids mixing with the water flow entering from the side wall of the flow guide part 143 in the first flow cavity 123, and cannot realize the adjustment of the fan-shaped water outlet angle.

[0085] With reference to Figures 6-8 In some specific embodiments of the present application, the spray head 100 further comprises a third flow channel 124, a second flow cavity 125, a second water outlet hole 126, an air suction chamber 127 and a third water outlet hole 112 which are sequentially communicated, wherein the second flow cavity 125 is provided with a second flow guide column 131, the second water outlet hole 126 is exposed in the air suction chamber 127, and the second water outlet hole 126 and the third water outlet hole 112 are correspondingly arranged in the direction of water flow, the water flow flowing out of the second water outlet hole 126 can flow out of the third water outlet hole 112 after passing through the air suction chamber 127, and the air suction chamber 127 is provided with an air suction hole which is communicated with the outside. When the water flow flows out of the second water outlet hole 126, a negative pressure area is formed near the second water outlet hole 126 due to the Venturi principle, the outside air enters the air suction chamber 127 through the air suction hole and mixes with the water flow to form bubble water, and the bubble water is sprayed out of the third water outlet hole 112.
