[0070] This disclosure provides an exemplary embodiment of a waterway switching mechanism 40, referring to... Figures 1-4As shown, the water circuit switching mechanism 40 may include a water outlet structure 41, a water outlet valve core 42, and an adjustment part 43. The water outlet structure 41 is provided with a water outlet chamber 411, and the water outlet structure 41 is provided with a main water inlet channel 412, a first water outlet channel 413, and a second water outlet channel 414 communicating with the water outlet chamber 411. The main water inlet channel 412 is used to connect to the water outlet of the water pump 20. The water outlet valve core 42 is located in the water outlet chamber 411 and includes a first water outlet sealing part 422 and a second water outlet sealing part 423. The adjustment part 43 is used to drive the water outlet valve core 42 to move so that the first water outlet sealing part 422 seals the first water outlet channel 413 and the second water outlet channel 414 is open, or the second water outlet sealing part 423 seals the second water outlet channel 414 and the first water outlet channel 413 is open.

[0071] The water circuit switching mechanism 40 disclosed herein includes an adjusting unit 43 that drives the outlet valve core 42 to move, such that the first outlet sealing part 422 seals the first outlet channel 413, while the second outlet sealing part 423 is not sealed in the second outlet channel 414. That is, when the first outlet channel 413 is not open, the second outlet channel 414 is open, allowing water from the outlet chamber 411 to flow out only through the second outlet channel 414; or, the second outlet sealing part 423 seals the second outlet channel 414, while the first outlet sealing part 422 is not sealed in the first outlet channel 413. That is, when the second outlet channel 414 is not open, the first outlet channel 413 is open, allowing water from the outlet chamber 411 to flow out only through the first outlet channel 413. This allows one water pump 20 to connect to two water spraying devices, providing a water source for both devices, reducing the number of water pumps 20 required, and thus lowering costs.

[0072] In some exemplary embodiments of this disclosure, reference is made to Figure 1 and Figure 2 As shown, the water outlet structure 41 has an outlet chamber 411. The water outlet structure 41 has a main inlet channel 412, a first outlet channel 413, and a second outlet channel 414 connected to the outlet chamber 411. Specifically, the water outlet structure 41 has a main inlet channel 412, a first outlet channel 413, and a second outlet channel 414, with one end of each channel connected to the outlet chamber 411. The first outlet channel 413 and the second outlet channel 414 can be correspondingly connected to opposite ends of the outlet chamber 411 along the second direction Y. The other end of the main inlet channel 412 is used to connect to the outlet of the water pump 20. Water flowing in through the main inlet channel 412 can flow through the outlet chamber 411 to the first outlet channel 413 and the second outlet channel 414.

[0073] Specifically, the water outlet structure 41 may include a first housing portion, a first water outlet pipe, and a second water outlet pipe. The first housing portion contains a water outlet cavity 411 and a main water inlet channel 412. The water outlet cavity 411 may be configured as a cylinder extending along the second direction Y, and both ends of the water outlet cavity 411 positioned opposite each other in the second direction Y are open, ensuring that neither end of the water outlet cavity 411 is blocked. The main water inlet channel 412 connects to the middle of the water outlet cavity 411.

[0074] A first water outlet pipe is provided with a first water outlet channel 413, one end of which is connected to an open end of a water outlet cavity 411, so that the first water outlet channel 413 is connected to the water outlet cavity 411; a second water outlet pipe is provided with a second water outlet channel 414, one end of which is connected to the other open end of a water outlet cavity 411, so that the second water outlet channel 414 is connected to the water outlet cavity 411; and the first water outlet channel 413 and the second water outlet channel 414 are connected one-to-one to the opposite ends of the water outlet cavity 411 along the second direction Y.

[0075] Of course, in some other exemplary embodiments of this disclosure, the water outlet cavity 411 can be configured as a prism-shaped tube extending along the second direction Y, that is, the radial cross section of the water outlet cavity 411 can be configured as various regular or irregular polygons.

[0076] In some exemplary embodiments of this disclosure, reference is made to Figure 1 and Figure 2 As shown, a water outlet valve core 42 is provided in the water outlet chamber 411. The water outlet valve core 42 may include a water outlet main body 421, a first water outlet sealing part 422 and a second water outlet sealing part 423.

[0077] The water outlet body 421 can be configured in a shape that matches the water outlet cavity 411; for example, if the water outlet cavity 411 is cylindrical, the water outlet body 421 can be cylindrical; if the water outlet cavity 411 is a quadrangular prism, the water outlet body 421 can be quadrangular prism. A water outlet space 4111 is provided between the water outlet body 421 and the cavity wall of the water outlet cavity 411; for example, a groove can be provided on the side of the water outlet body 421, forming the water outlet space 4111; alternatively, the radial dimension of the water outlet body 421 can be smaller than the radial dimension of the water outlet cavity 411, and the water outlet space 4111 can be formed between the outer peripheral surface of the water outlet body 421 and the cavity wall of the water outlet cavity 411. The main water inlet channel 412 is connected to the water outlet space 4111, allowing water flowing in through the main water inlet channel 412 to flow into the water outlet space 4111.

[0078] The first water outlet sealing part 422 and the second water outlet sealing part 423 are located at opposite ends of the water outlet main body 421 along the second direction Y. Specifically, the first water outlet sealing part 422 is located at one end of the water outlet main body 421 along the second direction Y, and the second water outlet sealing part 423 is located at the other end of the water outlet main body 421 along the second direction Y. The first water outlet sealing part 422 is used to seal the first water outlet channel 413, preventing water from flowing through the first water outlet channel 413. The second water outlet sealing part 423 is used to seal the second water outlet channel 414, preventing water from flowing through the second water outlet channel 414.

[0079] Of course, in some other exemplary embodiments of this disclosure, reference is made to Figure 4 The water outlet valve core 42 shown may not include the water outlet main body 421, but only the first water outlet sealing part 422 and the second water outlet sealing part 423.

[0080] In some exemplary embodiments of this disclosure, reference is made to Figure 1 and Figure 2 As shown, the adjusting part 43 is connected to the water outlet main body 421. The adjusting part 43 is used to drive the water outlet valve core 42 to move along the second direction Y, so that the first water outlet sealing part 422 seals the first water outlet channel 413, and the second water outlet sealing part 423 is not sealed in the second water outlet channel 414. That is, when the first water outlet channel 413 is not open, the second water outlet channel 414 is open, so that the water in the water outlet chamber 411 can only flow out through the second water outlet channel 414; or, the second water outlet sealing part 423 seals the second water outlet channel 414, and the first water outlet sealing part 422 is not sealed in the first water outlet channel 413. That is, when the second water outlet channel 414 is not open, the first water outlet channel 413 is open, so that the water in the water outlet chamber 411 can only flow out through the first water outlet channel 413. This allows one water pump 20 to be connected to two water spraying devices, providing a water source for both water spraying devices, saving the number of water pumps 20 used, and thus reducing costs.

[0081] The water source required by the water switching mechanism 40 mentioned above all comes from the water source connected to the water pump 20, which cannot meet the different water source requirements of the two water spraying devices.

[0082] In some exemplary embodiments of this disclosure, reference is made to Figure 1 and Figure 3 As shown, the water circuit switching mechanism 40 also includes a water inlet structure 44 and a water inlet valve core 45.

[0083] The water inlet structure 44 is provided with a water inlet chamber 441. The water inlet structure 44 is provided with a main water outlet channel 442, a first water inlet channel 443, and a second water inlet channel 444, all connected to the water inlet chamber 441. Specifically, the water inlet structure 44 has a main water outlet channel 442, a first water inlet channel 443, and a second water inlet channel 444, with one end of each channel connected to the water inlet chamber 441. The first water inlet channel 443 and the second water inlet channel 444 are correspondingly connected to opposite ends of the water inlet chamber 441 along the second direction Y. The other end of the main water outlet channel 442 is used to connect to the inlet of the water pump 20. Water flowing in through the first water inlet channel 443 and the second water inlet channel 444 can flow through the water inlet chamber 441 to the main water outlet channel 442.

[0084] Specifically, the water inlet structure 44 may include a second housing portion, a first water inlet pipe, and a second water inlet pipe. The second housing portion contains a water inlet cavity 441 and a main water outlet channel 442. The water inlet cavity 441 may be configured as a cylinder extending along the second direction Y, and both ends of the water inlet cavity 441 located opposite each other in the second direction Y are open, ensuring that neither end of the water inlet cavity 441 is blocked. The main water outlet channel 442 connects to the middle of the water inlet cavity 441.

[0085] A first water inlet pipe is provided with a first water inlet channel 443, one end of which is connected to an open end of a water inlet chamber 441, so that the first water inlet channel 443 is connected to the water inlet chamber 441; a second water inlet pipe is provided with a second water inlet channel 444, one end of which is connected to the other open end of a water inlet chamber 441, so that the second water inlet channel 444 is connected to the water inlet chamber 441; and the first water inlet channel 443 and the second water inlet channel 444 are connected one-to-one to the opposite ends of the water inlet chamber 441 along the second direction Y.

[0086] Of course, in some other exemplary embodiments of this disclosure, the water inlet cavity 441 can be configured as a prism-shaped tube extending along the second direction Y, that is, the radial cross section of the water inlet cavity 441 can be configured as various regular or irregular polygons.

[0087] In some exemplary embodiments of this disclosure, reference is made to Figure 1 and Figure 3 As shown, an inlet valve core 45 is provided in the inlet chamber 441. The inlet valve core 45 may include an inlet body 451, a first inlet sealing part 452 and a second inlet sealing part 453.

[0088] The water inlet body 451 can be configured in a shape that matches the water inlet cavity 441; for example, if the water inlet cavity 441 is cylindrical, the water inlet body 451 can be cylindrical; if the water inlet cavity 441 is a quadrangular prism, the water inlet body 451 can be a quadrangular prism. A water inlet space 4411 is provided between the water inlet body 451 and the cavity wall of the water inlet cavity 441; for example, a groove can be provided on the side of the water inlet body 451, forming the water inlet space 4411; alternatively, the radial dimension of the water inlet body 451 can be smaller than the radial dimension of the water inlet cavity 441, and the water inlet space 4411 can be formed between the outer peripheral surface of the water inlet body 451 and the cavity wall of the water inlet cavity 441. The main water outlet channel 442 is connected to the water inlet space 4411, allowing water in the water inlet space 4411 to flow out through the main water outlet channel 442.

[0089] The first water inlet sealing part 452 and the second water inlet sealing part 453 are disposed at opposite ends of the water inlet main body 451 along the second direction Y. That is, the first water inlet sealing part 452 is disposed at one end of the water inlet main body 451 along the second direction Y, and the second water inlet sealing part 453 is disposed at the other end of the water inlet main body 451 along the second direction Y. The first water inlet sealing part 452 is used to seal the first water inlet channel 443, so that water cannot flow through the first water inlet channel 443. The second water inlet sealing part 453 is used to seal the second water inlet channel 444, so that water cannot flow through the second water inlet channel 444.

[0090] Of course, in some other exemplary embodiments of this disclosure, reference is made to Figure 4 The inlet valve core 45 shown may not include the inlet body 451, but only the first inlet sealing part 452 and the second inlet sealing part 453.

[0091] Reference Figure 1 and Figure 3 As shown, the adjusting part 43 is also connected to the water inlet body part 451. The adjusting part 43 is also used to drive the water inlet valve core 45 to move along the second direction Y, so that the first water inlet sealing part 452 seals the first water inlet channel 443, and the second water inlet sealing part 453 is not sealed in the second water inlet channel 444. That is, when the first water inlet channel 443 is not open, the second water inlet channel 444 is open, so that water can only flow into the water inlet chamber 441 through the second water inlet channel 444; or, the second water inlet sealing part 453 seals the second water inlet channel 444, and the first water inlet sealing part 452 is not sealed in the first water inlet channel 443. That is, when the second water inlet channel 444 is not open, the first water inlet channel 443 is open, so that water can only flow into the water inlet chamber 441 through the first water inlet channel 443. This arrangement allows the first water inlet channel 443 and the second water inlet channel 444 to be connected to different water sources, satisfying the different water source requirements of the two water spray devices.

[0092] Optionally, refer to Figure 1 As shown, the first water outlet channel 413 and the first water inlet channel 443 can be located on the same side of the water circuit switching mechanism 40. The first water outlet channel 413 and the first water inlet channel 443 are simultaneously sealed or simultaneously opened, and are used to provide a water source for the same water spraying device. The second water outlet channel 414 and the second water inlet channel 444 can be located on the same side of the water circuit switching mechanism 40. The second water outlet channel 414 and the second water inlet channel 444 are simultaneously sealed or simultaneously opened, and are used to provide a water source for the same water spraying device.

[0093] Of course, in some other exemplary embodiments of this disclosure, the first water outlet channel 413 and the first water inlet channel 443 may also be located on different sides of the water circuit switching mechanism 40. However, the first water outlet channel 413 and the first water inlet channel 443 are also simultaneously sealed or simultaneously opened so that the first water outlet channel 413 and the first water inlet channel 443 provide a water source for the same water spraying device. The second water outlet channel 414 and the second water inlet channel 444 may also be located on different sides of the water circuit switching mechanism 40. However, the second water outlet channel 414 and the second water inlet channel 444 are also simultaneously sealed or simultaneously opened so that the second water outlet channel 414 and the second water inlet channel 444 provide a water source for the same water spraying device.

[0094] Optionally, refer to Figure 1 and Figure 2 As shown, the water outlet structure 41 is provided with a first through hole 415, and the water outlet body part 421 is provided with a second through hole 4211. The first through hole 415 and the second through hole 4211 extend along the third direction Z, that is, the central axis of the first through hole 415 and the second through hole 4211 extends along the third direction Z.

[0095] It should be noted that the third direction Z intersects the second direction Y; for example, the third direction Z is perpendicular to the second direction Y.

[0096] Reference Figure 1 and Figure 2 As shown, the adjusting part 43 may include a rotating shaft 431 and a first cam 432. The rotating shaft 431 is rotatably and sealingly fitted within the first through hole 415. Specifically, two sealing grooves are provided on the rotating shaft 431, and a sealing ring is provided in each sealing groove. The sealing ring protrudes from the sealing groove and is located between the rotating shaft 431 and the hole wall of the first through hole 415. The two sealing rings achieve a seal between the rotating shaft 431 and the hole wall of the first through hole 415. The first through hole 415 is a circular through hole, and the rotating shaft 431 is a cylindrical rotating shaft 431, so that the rotating shaft 431 is rotatably fitted within the first through hole 415.

[0097] The first cam 432 is connected to the rotating shaft 431; the first cam 432 is rotatably fitted into the second through hole 4211, and the first cam 432 rotates to drive the water outlet valve core 42 to move along the second direction Y.

[0098] Specifically, the second through hole 4211 can be configured as a rectangular through hole, the radial cross-section of the first cam 432 is a quarter circle or other cam shape, and the width of the second through hole 4211 along the second direction Y is slightly larger than the radius of the first cam 432 to ensure sufficient fit between the first cam 432 and the second through hole 4211 and to avoid interference. (Refer to...) Figure 1 and Figure 2 As shown, the first cam 432 is currently abutting against the side near the first water outlet seal 422, causing the first water outlet seal 422 to seal the first water outlet channel 413; after rotating the shaft clockwise by 90°, the first cam 432 also rotates the shaft clockwise by 90°, and the first cam 432 drives the water outlet valve core 42 to move along the second direction Y towards the side of the second water outlet channel 414, until the first cam 432 abuts against the side near the second water outlet seal 423, causing the second water outlet seal 423 to seal the second water outlet channel 414.

[0099] Of course, in some other exemplary embodiments of this disclosure, the second through hole 4211 can also be configured as a circular through hole, and the first cam 432 can also be configured as a structure with a protrusion on a circular structure. Alternatively, a through groove extending along the second direction Y can be provided on the top of the water outlet structure 41, and two sealing plates can be provided on both sides of the through groove, with the two sealing plates overlapping each other to prevent water from flowing out of the through groove; the adjusting part 43 can also include an adjusting rod, which is fixedly connected to the water outlet main body 421 and extends to the outside of the water outlet structure 41 through the two sealing plates, and the water outlet valve core 42 can be moved along the second direction Y by moving the adjusting rod.

[0100] In some exemplary embodiments of this disclosure, reference is made to Figure 1 and Figure 3 As shown, the water inlet structure 44 is connected to the water outlet structure 41 to form a common wall 416. Specifically, the water inlet structure 44 is connected to the water outlet structure 41 along the third direction Z to form a common wall 416 perpendicular to the third direction Z. A third through hole 4161 is provided on the common wall 416, and a fourth through hole 4511 is provided on the water inlet body 451. The third through hole 4161 and the fourth through hole 4511 extend along the third direction Z.

[0101] The adjusting part 43 may further include a connecting shaft 433 and a second cam 434; the connecting shaft 433 is connected to the end of the first cam 432 opposite to the connecting shaft 433, and the connecting shaft 433 is rotatably and sealingly fitted within the third through hole 4161; specifically, a sealing groove is provided on the connecting shaft 433, and a sealing ring is provided in each sealing groove. The sealing ring protrudes from the sealing groove and is located between the connecting shaft 433 and the hole wall of the third through hole 4161, thereby achieving a seal between the connecting shaft 433 and the hole wall of the third through hole 4161. The third through hole 4161 is set as a circular through hole, and the connecting shaft 433 is set as a cylindrical connecting shaft 433, so that the connecting shaft 433 is rotatably fitted within the third through hole 4161.

[0102] The second cam 434 is connected to the connecting shaft 433. The second cam 434 is rotatably fitted into the fourth through hole 4511. The second cam 434 rotates to drive the water inlet valve core 45 to move.

[0103] For example, the fourth through hole 4511 can be set as a rectangular through hole, and the radial cross section of the second cam 434 is a quarter circle or other cam shape. The width of the fourth through hole 4511 along the second direction Y is slightly larger than the radius of the second cam 434 to ensure the fit between the second cam 434 and the fourth through hole 4511 and avoid interference. When the second cam 434 abuts against the side near the first water inlet seal 452, the first water inlet seal 452 seals the first water inlet channel 443. After rotating the shaft 90° clockwise, the second cam 434 also rotates the shaft 90° clockwise. The second cam 434 drives the water inlet valve core 45 to move along the second direction Y towards the side of the second water inlet channel 444 until the second cam 434 abuts against the side near the second water inlet seal 453, so that the second water inlet seal 453 seals the second water inlet channel 444.

[0104] Of course, in some other exemplary embodiments of this disclosure, the fourth through hole 4511 can also be configured as a circular through hole, and the second cam 434 can also be configured as a structure with a protrusion on a circular structure. Alternatively, a through groove extending along the second direction Y can be provided in the common wall 416, and two sealing plates can be provided on both sides of the through groove, with the two sealing plates overlapping each other to prevent water from flowing out of the through groove; the adjusting part 43 can also include a connecting rod, which is fixedly connected between the water outlet main body 421 and the water inlet main body 451, and extends into the water inlet cavity 441 through the two sealing plates. By moving the adjusting rod, the water outlet valve core 42 and the water inlet valve core 45 can be moved along the second direction Y.

[0105] In other exemplary embodiments of this disclosure, reference is made to Figure 4As shown, since the water outlet structure and the water inlet structure are basically the same, and the water outlet valve core and the water inlet valve core are basically the same, they are represented by a single figure; the first water outlet channel 413 and the second water outlet channel 414 may not be connected to the opposite ends of the water outlet cavity 411 along the second direction Y, and the first water outlet channel 413 and the second water outlet channel 414 may be connected to the two sides of the water outlet cavity 411 that are set at 90°; in this case, the axial direction of the first water outlet sealing part 422 and the axial direction of the second water outlet sealing part 423 are also basically set at 90°; the adjusting part 43 can drive the first water outlet sealing part 422 to move along the second direction Y, and the adjusting part 43 can drive the second water outlet sealing part 423 to move along the first direction X. The first water inlet channel 443 and the second water inlet channel 444 may not be correspondingly connected to the opposite ends of the water inlet cavity 441 along the second direction Y. The first water inlet channel 443 and the second water inlet channel 444 may be connected to the two sides of the water inlet cavity 441 that are set at 90°. In this case, the axial direction of the first water inlet sealing part 452 and the axial direction of the second water inlet sealing part 453 are also basically set at 90°. The adjusting part 43 can drive the first water inlet sealing part 452 to move along the second direction Y, and the adjusting part 43 can drive the second water inlet sealing part 453 to move along the first direction X. The first direction X may be perpendicular to the second direction Y.

[0106] Of course, the first water outlet channel 413 and the second water outlet channel 414 can also be connected to the two sides of the water outlet cavity 411 that are set at other angles, and the first water inlet channel 443 and the second water inlet channel 444 can also be connected to the two sides of the water inlet cavity 441 that are set at other angles; in this case, the first direction X can intersect with the second direction Y.

[0107] In some exemplary embodiments of this disclosure, reference is made to Figure 1 and Figure 5 As shown, the water circuit switching mechanism 40 may further include a switching switch 46 and a controller 410. The switching switch 46 may include a switch button 461 or a microswitch. The output terminal of the switching switch 46 is electrically connected to the input terminal of the controller 410, and the output terminal of the controller 410 is electrically connected to the control terminal of the water pump 20. The switching switch 46 has a normally open state and a closed state. The controller 410 detects which state the switching switch 46 is in and controls the operating mode of the water pump 20 according to the detected state. This satisfies the requirement that the water pump 20 of the two spray devices operates in different modes.

[0108] In this case, the rotating shaft 431 may include a main shaft portion 4311, a third cam 4312, and a mode switching knob 4313; the main shaft portion 4311 is rotatably and sealed within the first through hole 415, and the specific fitting structure has been described in detail above, so it will not be repeated here.

[0109] The third cam 4312 is connected to the end of the main shaft 4311 that is away from the first cam 432, and the third cam 4312 is located outside the water outlet structure 41.

[0110] The mode switching knob 4313 is connected to the side of the third cam 4312 opposite to the first cam 432, and the mode switching knob 4313 is located outside the housing 50 of the water spray device. Rotation of the mode switching knob 4313 causes the third cam 4312 to rotate, engaging or disengaging with the switch button 461 to select either the first mode or the second mode. The controller 410 is used to control the water pump to operate in the first working mode according to the first mode, and the controller 410 is used to control the water pump to operate in the second working mode according to the second mode.

[0111] Specifically, when the user rotates the mode switching knob 4313, the knob rotates the third cam 4312, causing it to abut against the switch button 461, thus placing the switch 46 in the closed state (first mode). The controller 410 detects that the switch 46 is in the closed state (first mode) and controls the water pump 20 to operate in the closed state mode. That is, the controller 410 controls the water pump to operate in the first working mode according to the first mode. When the user rotates the mode switching knob 4313 again, the knob rotates the third cam 4312 again, causing it to abut against the switch button 461, thus placing the switch 46 in the normally open state (second mode). The controller 410 detects that the switch 46 is in the normally open state (second mode) and controls the water pump 20 to operate in the normally open state mode. That is, the controller 410 controls the water pump to operate in the second working mode according to the second mode.

[0112] The first working mode can be the water gun mode, where the water pump 20 operates intermittently, and the interval can be set as needed. The second working mode can be the continuous working mode. Of course, other working modes are also possible, but they will not be elaborated on here.

[0113] Optionally, refer to Figure 5 As shown, the water path switching mechanism 40 may also include a limiting component 47, which is used to limit the adjustment part 43. The limiting component 47 is located on the side of the third cam 4312 away from the switching switch 46, so that the third cam 4312 is located between the limiting component 47 and the switching switch 46.

[0114] Specifically, a first recess 43121 and a second recess 43122 are provided on the wheel surface of the third cam 4312; both the first recess 43121 and the second recess 43122 are recessed towards the central axis of the third cam 4312; the first recess 43121 and the second recess 43122 are set at 90°, that is, the angle between the central axis of the first recess 43121 pointing towards the central axis of the third cam 4312 and the central axis of the second recess 43122 pointing towards the central axis of the third cam 4312 is approximately 90°. The first recess 43121 and the second recess 43122 can be through slots penetrating both planes of the third cam 4312. Of course, the first recess 43121 and the second recess 43122 can also be blind holes provided on the wheel surface of the third cam 4312.

[0115] The limiting assembly 47 may include a limiting seat 471, a limiting elastic element 472, and a limiting spring block 473. The limiting seat 471 may be fixed outside the water outlet structure 41, and a limiting groove 4711 is provided on the limiting seat 471, with the opening of the limiting groove 4711 facing the third cam 4312. The limiting elastic element 472 is disposed in the limiting groove 4711, and the limiting elastic element 472 may be a helical spring, with one end of the limiting elastic element 472 fixed to the bottom wall of the limiting groove 4711. One end of the limiting spring block 473 is connected to the opposite end of the limiting elastic member 472, and the other end of the limiting spring block 473 protrudes from the limiting groove 4711, so that the limiting spring block 473 can be locked in the first recess 43121 or the second recess 43122, so that the limiting spring block 473 can limit the third cam 4312, prevent the third cam 4312 from rotating arbitrarily, and prevent it from affecting the contact relationship between the third cam 4312 and the switch button 461, thereby causing confusion in the working mode of the controller 410 and the water pump 20.

[0116] Optionally, the wheel surface of the third cam 4312 is further provided with a protrusion 43123 and a flattened surface 43124, which are also set at 90°. The protrusion 43123 is positioned opposite to the first recess 43121, and the flattened surface 43124 is positioned opposite to the second recess 43122. When the protrusion 43123 abuts against the switch button 461, the limiting spring 473 is engaged in the first recess 43121, fixing the working mode; when the flattened surface 43124 is opposite to the switch button 461 and the third cam 4312 is not engaged with the switch button 461, the limiting spring 473 is engaged in the second recess 43122, fixing the working mode.

[0117] Of course, in some other exemplary embodiments of this disclosure, the limiting component 47 and the switching switch 46 may be set at 90° relative to the central axis of the third cam 4312. In this case, the protrusion 43123 and the first recess 43121 are also set at 90°, and the flattened plane 43124 and the second recess 43122 are also set at 90°. Similarly, when the protrusion 43123 abuts against the switch button 461, the limiting spring 473 is locked in the first recess 43121, thus fixing the working mode; when the flattened plane 43124 is opposite to the switch button 461 and the third cam 4312 does not abut against the switch button 461, the limiting spring 473 is locked in the second recess 43122, thus fixing the working mode.

[0118] Optionally, an annular baffle 474 is provided at the opening of the limiting groove 4711, such that the opening area of ​​the limiting groove 4711 is smaller than the internal radial cross-sectional area. The limiting spring block 473 may include a first part and a second part connected to each other. The second part fits into the limiting groove 4711, and the first part extends out of the limiting groove 4711 through a through hole on the annular baffle 474. The first part may be cone-shaped, so that the first part can easily be inserted into the first recess 43121 and the second recess 43122, and disengage from the first recess 43121 and the second recess 43122. The radial cross-sectional area of ​​the second part is larger than that of the first part, and the radial cross-sectional area of ​​the second part is larger than the area of ​​the through hole on the annular baffle 474, so that the second part cannot disengage from the annular baffle 474. The annular baffle 474 can limit the movement distance of the limiting spring block 473.

[0119] In some exemplary embodiments of this disclosure, reference is made to Figure 2 As shown, the first water outlet channel 413 may include a first segment 4131 and a second segment 4132 connected in sequence. The first segment 4131 is connected to the water outlet cavity 411. The end of the second segment 4132 opposite to the first segment 4131 is the first water outlet. The extension direction of the first segment 4131 intersects the extension direction of the second segment 4132. For example, the extension direction of the first segment 4131 is perpendicular to the extension direction of the second segment 4132, so that the first water outlet channel 413 includes two segments that are perpendicular to each other.

[0120] Reference Figure 2As shown, the second water outlet channel 414 may include a third segment 4141 and a fourth segment 4142 connected in sequence. The third segment 4141 is connected to the water outlet cavity 411, and the end of the fourth segment 4142 opposite to the third segment 4141 is the second water outlet. The extension direction of the third segment 4141 intersects the extension direction of the fourth segment 4142. For example, the extension direction of the third segment 4141 is perpendicular to the extension direction of the fourth segment 4142, so that the second water outlet channel 414 includes two segments that are perpendicular to each other.

[0121] Reference Figure 3 As shown, the first water inlet channel 443 may include a fifth segment 4431 and a sixth segment 4432 connected in sequence. The fifth segment 4431 is connected to the water inlet cavity 441, and the end of the sixth segment 4432 opposite to the fifth segment 4431 is the first water inlet. The extension direction of the fifth segment 4431 intersects the extension direction of the sixth segment 4432. For example, the extension direction of the fifth segment 4431 is perpendicular to the extension direction of the sixth segment 4432, so that the first water inlet channel 443 includes two segments that are perpendicular to each other.

[0122] Reference Figure 3 As shown, the second water inlet channel 444 may include a seventh segment 4441 and an eighth segment 4442 connected in sequence. The seventh segment 4441 is connected to the water inlet cavity 441. The end of the eighth segment 4442 opposite to the seventh segment 4441 is the second water inlet. The extension direction of the seventh segment 4441 intersects the extension direction of the eighth segment 4442. For example, the extension direction of the seventh segment 4441 is perpendicular to the extension direction of the eighth segment 4442, so that the second water inlet channel 444 includes two segments that are perpendicular to each other.

[0123] Of course, the extension direction of the first segment 4131 and the extension direction of the second segment 4132 may not be perpendicular, and can be set to other angles as needed; the extension direction of the third segment 4141 and the extension direction of the fourth segment 4142 may not be perpendicular, and can be set to other angles as needed; the extension direction of the fifth segment 4431 and the extension direction of the sixth segment 4432 may not be perpendicular, and can be set to other angles as needed; the extension direction of the seventh segment 4441 and the extension direction of the eighth segment 4442 may not be perpendicular, and can be set to other angles as needed.

[0124] Optionally, refer to Figure 2 and Figure 3As shown, the end of the first segment 4131 furthest from the outlet cavity 411 is a closed end, meaning that the end of the first segment 4131 furthest from the outlet cavity 411 has no opening; the end of the third segment 4141 furthest from the outlet cavity 411 is a closed end, meaning that the end of the third segment 4141 furthest from the outlet cavity 411 has no opening; the end of the fifth segment 4431 furthest from the inlet cavity 441 is a closed end, meaning that the end of the fifth segment 4431 furthest from the inlet cavity 441 has no opening; and the end of the seventh segment 4441 furthest from the inlet cavity 441 is a closed end, meaning that the end of the seventh segment 4441 furthest from the inlet cavity 441 has no opening.

[0125] The waterway switching mechanism 40 may further include a first elastic part 481, a second elastic part 482, a third elastic part 483, and a fourth elastic part 484; the first elastic part 481, the second elastic part 482, the third elastic part 483, and the fourth elastic part 484 may be, but are not limited to, helical springs. The first elastic part 481, the second elastic part 482, the third elastic part 483, and the fourth elastic part 484 may be sheet springs.

[0126] The first elastic part 481 is disposed between the first water outlet sealing part 422 and the closed end of the first segment 4131; the second elastic part 482 is disposed between the second water outlet sealing part 423 and the closed end of the third segment 4141; the third elastic part 483 is disposed between the first water inlet sealing part 452 and the closed end of the fifth segment 4431; and the fourth elastic part 484 is disposed between the second water inlet sealing part 453 and the closed end of the seventh segment 4441.

[0127] When the first water outlet seal 422 is not sealed, water needs to flow out from the gap between the first water outlet seal 422 and the first water outlet channel 413. The water flows from the water outlet body 421 to the first water outlet seal 422. The water flow will exert a certain pressure on the first water outlet seal 422. Under the action of the water flow, the gap between the first water outlet seal 422 and the first water outlet channel 413 may be reduced or even the first water outlet seal 422 may be resealed in the first water outlet channel 413. The first elastic part 481 can provide a certain rebound force for the first water outlet seal 422 to resist the action of the water flow, so as to avoid the consequences of the gap between the first water outlet seal 422 and the first water outlet channel 413 being reduced or even the first water outlet seal 422 being resealed in the first water outlet channel 413.

[0128] Similarly, when the second water outlet seal 423 is not sealed, water needs to flow out from the gap between the second water outlet seal 423 and the second water outlet channel 414. The water flows from the water outlet body 421 to the second water outlet seal 423. The water flow will exert a certain pressure on the second water outlet seal 423. Under the action of the water flow, the gap between the second water outlet seal 423 and the second water outlet channel 414 may be reduced or even the second water outlet seal 423 may be resealed in the second water outlet channel 414. The second elastic part 482 can provide a certain rebound force for the second water outlet seal 423 to resist the action of the water flow, and avoid the consequences of the gap between the second water outlet seal 423 and the second water outlet channel 414 being reduced or even the second water outlet seal 423 being resealed in the second water outlet channel 414.

[0129] When the first water inlet seal 452 is not sealed, water needs to flow in through the gap between the first water inlet seal 452 and the first water inlet channel 443. The third elastic part 483 can help open the first water inlet seal 452, which is conducive to the passage of water.

[0130] Similarly, when the second water inlet seal 453 is not sealed, water needs to flow in through the gap between the second water inlet seal 453 and the second water inlet channel 444. The fourth elastic part 484 can help open the second water inlet seal 453, which is conducive to the passage of water.

[0131] Optionally, refer to Figure 2 and Figure 3 As shown, the end of the first segment 4131 near the water outlet cavity 411 is set as a conical surface. For example, the end of the first segment 4131 near the water outlet cavity 411 can be set as a conical surface or a pyramidal surface, so that the opening area of ​​the first segment 4131 near the water outlet cavity 411 is large. The end of the third segment 4141 near the water outlet cavity 411 is set as a conical surface. For example, the end of the third segment 4141 near the water outlet cavity 411 can be set as a conical surface or a pyramidal surface, so that the opening area of ​​the third segment 4141 near the water outlet cavity 411 is large. The end of the fifth segment 4431 near the water inlet cavity 441 is set as a conical surface. For example, the end of the fifth segment 4431 near the water inlet cavity 441 can be set as a conical surface or a pyramidal surface, so that the opening area of ​​the fifth segment 4431 near the water inlet cavity 441 is large. The end of the seventh segment 4441 near the water inlet cavity 441 is set as a conical surface. For example, the end of the seventh segment 4441 near the water inlet cavity 441 can be set as a conical surface or a pyramidal surface, so that the opening area of ​​the seventh segment 4441 near the water inlet cavity 441 is larger.

This ensures that the conical surface of the first water outlet sealing part 422 can seal to the conical surface of the first segment 4131. Furthermore, a first groove is provided on the conical surface of the first water outlet sealing part 422, and a first sealing ring is provided within the first groove. The first sealing ring further ensures the sealing effect between the conical surface of the first water outlet sealing part 422 and the conical surface of the first segment 4131.

[0133] The second water outlet sealing part 423 is provided with a conical surface and is sealed to the conical surface of the third section 4141 near the water outlet cavity 411.

This ensures that the conical surface of the second water outlet sealing part 423 can seal to the conical surface of the third section 4141. Furthermore, a second groove is provided on the conical surface of the second water outlet sealing part 423, and a second sealing ring is provided within the second groove. The second sealing ring further ensures the sealing effect between the conical surface of the second water outlet sealing part 423 and the conical surface of the third section 4141.

[0134] The first water inlet sealing part 452 is provided with a conical surface and is sealed to the conical surface of the fifth segment 4431 near the water inlet cavity 441.

When the end of the seventh segment 4441 near the water inlet cavity 441 is a conical surface, the second water inlet sealing part 453 is also provided with a conical surface; when the end of the seventh segment 4441 near the water inlet cavity 441 is a pyramidal surface, the second water inlet sealing part 453 is also provided with a pyramidal surface. This ensures that the conical surface of the second water inlet sealing part 453 can seal to the conical surface of the seventh segment 4441. Furthermore, a fourth groove is provided on the conical surface of the second water inlet sealing part 453, and a fourth sealing ring is provided within the fourth groove. The fourth sealing ring further ensures the sealing effect between the conical surface of the second water inlet sealing part 453 and the conical surface of the seventh segment 4441.

[0136] In some exemplary embodiments of this disclosure, reference is made to Figure 2 As shown, the water circuit switching mechanism 40 may also include a one-way air vent valve 491. The one-way air vent valve 491 is connected to the first water outlet channel 413. The air in the first water outlet channel 413 can be discharged through the one-way air vent valve 491 to prevent the air in the first water outlet channel 413 from flowing to the water spraying device, thus preventing the water spraying device from being unable to take in water, thereby ensuring that the water spraying device can spray water.

[0137] Specifically, the one-way vent valve 491 may include a valve seat, a compression spring, and a silicone ball. The valve seat has a vent hole and a mounting cavity. The vent hole is connected to the mounting cavity, and a stepped surface is formed between the vent hole and the mounting cavity due to their different diameters. The compression spring and the silicone ball are located within the mounting cavity. One end of the compression spring abuts against the stepped surface, and the silicone ball abuts against the other end of the compression spring. A sealing surface that mates with the silicone ball is provided on the inner wall of the mounting cavity; the sealing surface may be a conical surface. When the first water outlet sealing part 422 is opened and not sealed with the conical surface of the first section 4131, water flows to the first water outlet channel 413. Air in the first water outlet channel 413 can be discharged through the one-way vent valve 491. When the pressure in the first water outlet channel 413 increases to the point that the compression spring is compressed, and the silicone ball abuts against the sealing surface, the one-way vent valve 491 closes, allowing water to flow through the first water outlet channel 413 to the water spraying device.

The water inlet of the water pump 20 is connected to the main water outlet channel 442; the spraying device may also include a liquid storage tank 80, which is disposed inside the main body 501 and located on the side of the water pump 20 away from the second spraying device 30. The liquid storage tank 80 has a first water outlet, which is connected to the first water inlet channel 443, so that the water stored in the liquid storage tank 80 can provide a water source for the first spraying device 10. The second water inlet channel 444 can be used to connect to an external water source.

[0148] In some exemplary embodiments of this disclosure, the water spraying device may further include a storage tank 80, which is disposed within the main body 501 and located on the side of the water pump 20 away from the second water spraying device 30.

That is, the inlet of the water pump 20 is not only connected to the storage tank 80, but also connected to an external water source, so that both the external water source and the storage tank 80 can provide water to the water pump 20.

[0149] In some example embodiments of this disclosure, the liquid storage tank 80 also has a second water outlet, which is connected between the second water spray device 30 and the second water outlet channel 414.
