For example, the one end B of the base is cylindrical, and the outer peripheral side thereof is threaded, and the one end B of the base is inserted into and screwed into the outlet pipe of the pump to communicate with the pump, so that the water flow is sucked into the pump, and then enters the shower arm via the base and the switching portion, and is ejected from the nozzle hole. When the spray arm rotates, the base is fixed and not rotated.

In some embodiments, the switching part 601 and the triggering part 602 are located between the base and the shower arm, and the switching part 601 includes: joint 6011 and switching member 6012; the switching member 6012 is movably disposed at the first and second positions between the shower arm 603 and the joint 6011; that is, the switching member 6012 moves up and down between a first position at which the switching member 6012 engages with the shower arm 603, which is the highest position of the switching member 6012, and a second position at which the switching member 6012 engages with the joint 6011, which is the lowest position of the switching member 6012.

In some embodiments, fig. 3 is a schematic view of a joint 6011 according to an embodiment of the present application, as shown in fig. 3, where the joint 6011 includes a first connection portion 801, for example, the first connection portion 801 is circular, as shown in fig. 1B and fig. 2, and the bottom surface of the shower arm 603 further includes a second connection portion 701, where the first connection portion 801 and the second connection portion 701 have the same shape and are connected by contact, for example, at least one first protrusion portion 8011 and at least one second protrusion portion 7011 protruding in a circumferential direction are disposed on the circular circumference of the first connection portion 801 and the second connection portion 701, respectively, and the first protrusion portion 8011 and the second protrusion portion 7011 may be penetrated by disposing a magnet or disposing a screw, so that the first connection portion 801 and the second connection portion 701 are connected. Wherein the joint 6011 and the switching member 6012 may rotate as the shower arm 603 rotates.

In some embodiments, as shown in fig. 1B, the trigger 602 includes:

a movable member 6021 that rotates with the spray device and a fixed member 6022 that does not rotate with the spray device,

when the movable member 6021 rotates with the shower device to the position of the fixed member 6022, the switching portion 601 is driven to move toward the first position to switch the flow passage.

In some embodiments, the moveable member 6021 is disposed below the switch member and the stationary member 6022 is secured to the base 604. Fig. 4 is a schematic diagram of a moving member and a fixed member according to an embodiment of the present application, as shown in fig. 4, for example, the base 604 further includes a circular ring portion 6043, the first cylinder portion 6041 and the second cylinder portion 6042 are disposed in a central hole of the circular ring portion 6043 in a penetrating manner, the fixed member 6022 of the base is a protruding portion fixed on the base (for example, a peripheral edge of the circular ring portion 6043 of the base), the moving member 6021 is a rod portion, and an upper end of the rod portion may be disposed on a peripheral edge of a lower surface of the first connecting portion 801 in a penetrating manner (for example, outer diameters of the circular ring portion 6043 and the first connecting portion 801 are substantially the same). However, embodiments of the present application are not limited thereto, for example, the fixed member 6022 and the movable member 6021 are opposing magnets.

In some embodiments, when the movable member rotates with the spray device to the position of the fixed member, the movable member generates a displacement in a direction toward the first position to drive the switching portion to move toward the first position. For example, when the lever portion is rotated to the protruding portion, the protruding portion is lifted up to generate a displacement in the direction of the first position, or when the magnet of the movable member 6021 is rotated to the position of the fixed member 6022, the magnetic poles repel each other, so that the movable member 6021 is displaced in the direction of the first position. When the movable piece rotates to the position of the fixed piece along with the spraying device, the switching piece is driven to leave the second position, is separated from the connector and moves towards the first position to switch the flow passage.

For example, when the switching member is not driven and is located at the second position, the switching member may be in contact with the movable member, when the movable member rotates with the spray device to the position of the fixed member, the movable member is displaced in the direction of the first position, and the switching member is also displaced in the direction of the first position due to the contact of the switching member with the movable member, or the switching member is provided with a driving force for moving in the direction of the first position, or when the switching member is not driven and is located at the second position, the switching member is not in contact with the movable member, and when the movable member rotates with the spray device to the position of the fixed member, the switching member is in contact with the movable member after the movable member is displaced in the direction of the first position, and the switching member is also displaced in the direction of the first position due to the contact of the switching member with the movable member, or the switching member is provided with a driving force for moving in the direction of the first position.

In some embodiments, the trigger portion includes at least two moving members and at least two fixed members, the at least two moving members being disposed 180 ° apart in a circumferential direction of the rotation of the spray device, the at least two fixed members being disposed 180 ° apart in the circumferential direction of the rotation of the spray device.

For example, as shown in fig. 1B, the trigger part includes two movable members (lever parts) and two fixed members (protruding parts) provided at 180 ° intervals in the circumferential direction of the rotation of the spray device, and by providing at least two movable members and at least two of the fixed members, it is possible to cause the switching member to be provided with balanced and sufficient driving force.

In some embodiments, as shown in fig. 4, the joint 6011 further has a tubular portion 802, where the tubular portion 802 is disposed through a central position of the first connection portion 801, and the tubular portion 802 includes an upwardly extending cylindrical liquid outlet end 8021 and a downwardly extending liquid inlet end 8022, where an upper portion of the liquid outlet end 8021 has a central hole 80211, and a peripheral wall of a lower portion of the liquid outlet end 8021 has a peripheral hole 80212, where one or more peripheral holes 80212 may be provided, and embodiments of the present application are not limited thereto. The central hole 80211 and the peripheral hole 80212 are used for communicating with the flow channel, the liquid outlet end is communicated with the liquid inlet end, the liquid inlet end 8022 is communicated with the base, for example, the lower part of the liquid inlet end 8022 is inserted into the end A of the base to be communicated with the base.

In some embodiments, fig. 5 is a schematic top view of the switch member according to the embodiments of the present application, as shown in fig. 5, the switch member 6012 includes a centrally located through hole 1001, and when the switch member is in the second position, the liquid outlet end is disposed through the through hole, and a sidewall 10011 of the through hole covers the peripheral hole (completely covers, or covers a portion of the peripheral hole). Namely, the communication area between the peripheral holes and the flow channel is smaller than a first preset value, and the communication area between the central holes and the flow channel is larger than a second preset value; after the switching piece leaves the second position, the communication area between the peripheral hole and the flow channel is larger than the first preset value; when the switching piece is positioned at the first position, the communication area between the central hole and the flow channel is smaller than the second preset value. The first preset value and the second preset value may be determined according to needs, for example, the driving force generated by the water yield of the first preset value area is greater than the first value, and the driving force generated by the water yield of the second preset value area is greater than the second value. For example, when the switch is in the second position, the peripheral hole is not in communication with the flow passage, and the central hole is in communication with the flow passage; after the switching piece leaves the second position, the peripheral hole is communicated with the flow channel; when the switching piece is positioned at the first position, the communication area between the central hole and the flow passage is smaller than the second preset value.

In some embodiments, the switching member is driven to leave the second position by a driving force from the movable member and is driven to move toward the first position by a pressure of the cleaning liquid from at least the peripheral hole when the movable member rotates to the position of the fixed member. For example, the switching member is driven by the displacement of the movable member in the direction toward the first position, and is separated from the second position, and after the switching member is separated from the second position, the area of the side wall of the through hole of the switching member covering the peripheral hole is reduced, and the communication area between the peripheral hole and the flow passage is larger than the first preset value, so that the pressure of the cleaning liquid from the peripheral hole is continuously driven to move toward the first position, thereby providing a continuous stable driving force for the movement of the switching member through the peripheral hole and ensuring the movement of the switching member to the first position.

In some embodiments, as shown in fig. 2, a blocking portion 704 is disposed at the bottom of the spray arm, where when the switching member is located at the first position, the blocking portion 704 is configured to block a flow path between the central hole of the liquid outlet end and the flow channel, so that a communication area between the central hole and the flow channel is smaller than the second preset value.

In some embodiments, the blocking portion 704 is located at the center of the spray arm, the blocking portion 704 includes a plug 7041 and a slot 7042 located at the periphery of the plug, for example, the plug 7041 is circular, when the switch is located in the first position, the upper portion of the through hole 1001 is inserted into the slot 7042, and the lower portion of the through hole 1001 is at least partially overlapped with the upper portion of the liquid outlet end. After the upper portion of the through hole 1001 is inserted into the groove 7042, the plug 7041 is inserted into the through hole 1001 of the switching member to block the through hole 1001, so that a flow path between the central hole of the liquid outlet end and the flow path can be cut off, so that a communication area between the central hole and the flow path is smaller than the second preset value.

The following describes how the switching member performs flow channel switching.

In some embodiments, the switch further includes a flow aperture corresponding to a flow channel, the cleaning fluid being in communication with a set of flow channels via the peripheral aperture and the flow aperture when the switch is in the first position. For example, as shown in fig. 5, the shower arm includes a first flow channel and a second flow channel at both ends, so that the switching member includes flow holes 1002 and 1003, which respectively flow with one set of flow channels at both ends of the shower arm, and when the switching member falls back from the first position to the second position and is driven to move to the first position by the trigger portion, the position of the flow holes rotates relative to the shower arm, and the cleaning liquid is communicated with the other set of flow channels via the peripheral holes and the flow holes. The operation of switching the injection manner is performed in the foregoing embodiment by the switching member falling back from the first position to the second position and then being driven to move to the first position by the triggering portion.

In some embodiments, as shown in fig. 3, the joint 6011 is further provided with a first guiding portion 803, fig. 6 is a schematic view of the lower surface of the switching member according to the embodiment of the present application, and as shown in fig. 6, the lower surface of the switching member further includes a second guiding portion 1201, and when the switching member falls back to the second position, the position of the switching member is guided by interaction of the first guiding portion 803 and the second guiding portion 1201. For example, the first guide 803 is a partition (for example, 4 sheets) extending outward from the periphery of the tubular portion 802, and the second guide 1201 is a partition extending outward from the periphery of the through hole of the switching member, and the position of the switching member is guided by the partition of the partition, so that each time the switching member falls back to the second position, the flow hole of the switching member rotates to a fixed position (a position in the middle of the adjacent partition), and after the switching member moves to the first position again, the corresponding flow passage is conducted, and the other flow passage is blocked.

In some embodiments, the connector is further provided with a first magnet (not shown) and the switch is further provided with a second magnet (not shown), and when the switch is in the second position, the switch is fixed in the second position by interaction of the first magnet and the second magnet, so that relative movement between the switch and the connector is avoided.

In some embodiments, as shown in fig. 2, the bottom of the spray arm is further provided with a third guide portion 705, and the third guide portion 705 is a partition extending from the periphery of the slot 7042 of the blocking portion 704 for separating the flow channel. As shown in fig. 5, the upper surface of the switching member further includes a fourth guide portion 1004 for guiding the position of the switching member by the interaction of the third guide portion and the fourth guide portion when the switching member is moved to the first position. The position of the switching piece is guided through the baffle of the separating piece, so that each time the switching piece moves to the first position, the circulation hole of the switching piece rotates to a fixed position (the position in the middle of the adjacent separating piece), and the switching piece can conduct the corresponding flow channel to block the other flow channel. The third guide portion 705 may be regarded as the aforementioned partitions 71 and 72 for partitioning the flow path.

Wherein, stopping the pump operation may be replaced by reducing the pressure of the cleaning fluid flowing into the spraying device, starting the pump to operate again may be replaced by increasing the pressure of the cleaning fluid flowing into the spraying device, or stopping the pump operation may be replaced by cutting off the flow path between the pump and the spraying device, and starting the pump to operate again may be replaced by turning on the flow path between the pump and the spraying device again.
