The dish washer is a device capable of automatically cleaning tableware, generally comprises a base, an inner container and a door body, wherein the inner container is arranged on the base, the inner container is provided with a washing cavity, the door body is rotatably connected with the inner container and/or the base to seal or open the washing cavity, a bowl basket capable of being pulled out or pushed in is arranged in the washing cavity, when the door body opens the washing cavity, the bowl basket can be pulled out of the washing cavity by a user, at the moment, tableware can be loaded on the bowl basket, after loading is finished, the bowl basket is pushed into the washing cavity, then the door body is used for sealing the washing cavity, and washing can be performed in the washing cavity.

The washing chamber is internally provided with spray arms, a plurality of larger dish washers are divided into upper, middle and lower spray arms, the spray arms are arranged on spray arm installation seats, the spray arm installation seats are communicated with a washing pump in a base through a waterway, the washing pump is also communicated with the washing chamber, when the washing pump works, water in the washing chamber is pumped and conveyed to the spray arms, the spray arms are provided with nozzles, water flows are ejected from the nozzles of the spray arms under the action of pressure, and the spray arms rotate under the action of reverse driving force of the ejected water flows, so that the water flows are ejected onto tableware to clean the tableware. The water flow sprayed by the spray arm falls back to the washing cavity, the water flow is filtered by the filter screen and continuously circulates under the action of the washing pump until the washing is finished, and the water is discharged by the drainage pump.

The spray arm generates a driving force by spraying a water flow, thereby driving the spray arm to rotate clockwise or counterclockwise about the rotation axis. Generally, in order to enable the spray arm to continuously and stably rotate, the driving force generated by most of nozzles on the arm body at one side of the rotation axis of the spray arm is in the same direction, which means that when the spray arm is introduced with water flow, the spray arm can only rotate clockwise or anticlockwise, and the cleaning effect of unidirectional rotation of the spray arm needs to be improved.

As shown in fig. 1-7, in some embodiments, the sprayer includes a spray arm 1000, a spindle 2000, a diverter 3000, and a flight 4000.

The spray arm 1000 comprises a spray arm upper sheet 1100 and a spray arm lower sheet 1200, the spray arm upper sheet 1100 and the spray arm lower sheet 1200 are made of plastics, the spray arm upper sheet 1100 and the spray arm lower sheet 1200 are manufactured through injection molding, the edge of the spray arm upper sheet 1100 is opposite to the edge of the spray arm lower sheet 1200, the spray arm 1000 and the spray arm lower sheet 1200 are connected through welding, the spray arm 1000 further comprises a blocking rib 1203, the blocking rib 1203 is arranged between the spray arm upper sheet 1100 and the spray arm lower sheet 1200, a first flow channel 1300 and a second flow channel 1400 can be separated in the spray arm 1000, the blocking rib 1203 can be welded with the spray arm lower sheet 1200 first, or the blocking rib 1203 and the spray arm lower sheet 1200 are integrally injection molded, and when the spray arm upper sheet 1100 and the spray arm lower sheet 1200 are welded, the spray arm upper sheet 1100 and the blocking rib 1203 are welded, and the first flow channel 1300 and the second flow channel 1400 can be formed.

The arm top piece 1100 is further provided with a first nozzle 1101, the first nozzle 1101 is in communication with the first flow channel 1300, the first nozzle 1101 receives a water flow (the water flow is one of the fluids, hereinafter, the water flow is exemplified as a description of the water flow) in the first flow channel 1300, and the first nozzle 1101 is at a certain angle relative to the arm top piece 1100, so as to provide a driving force for the arm 1000 in a first direction, and drive the arm 1000 to rotate clockwise or anticlockwise. The upper spray arm piece 1100 is further provided with a second nozzle 1102, the second nozzle 1102 is communicated with the second flow channel 1400, the second nozzle 1102 receives water flow in the second flow channel 1400 and emits the water flow, the second nozzle 1102 is also at a certain angle relative to the upper spray arm piece 1100, but is oriented differently from the first nozzle 1101, so that a driving force in a second direction can be provided for the spray arm 1000, and the first direction and the second direction are different, so that the spray arm 1000 can be driven to rotate anticlockwise or rotate clockwise (if the first nozzle 1101 drives the spray arm 1000 to rotate clockwise, the second nozzle 1102 drives the spray arm 1000 to rotate anticlockwise, otherwise, if the first nozzle 1101 drives the spray arm 1000 to rotate anticlockwise, the second nozzle 1102 drives the spray arm 1000 to rotate clockwise, and the following description will be given by driving the spray arm 1000 to rotate clockwise by the first nozzle 1101). That is, two kinds of flow channels 3001 are formed in the spray arm 1000, the first flow channel (the first flow channel 1300) is communicated with the first nozzle 1101, the second flow channel (the second flow channel 1400) is communicated with the second nozzle 1102, and as long as the water flow is controlled to flow to the first flow channel 1300 or the second flow channel 1400, two rotation directions of clockwise rotation and anticlockwise rotation can be realized on the same spray arm 1000, thereby avoiding missing washing dead angles and improving washing effect.

The rotation shaft 2000 supports the rotation of the spray arm 1000, and rotatably mounts the spray arm 1000 to the spray arm base 5000. Specifically, the rotating shaft 2000 is of a hollow structure and is configured to receive water flowing out of the spray arm seat 5000, and is fixed to the spray arm 1000, for example, fixed to the spray arm lower plate 1200, and the fixing between the rotating shaft 2000 and the spray arm lower plate 1200 may be welded or integrally formed. The rotation shaft 2000 is inserted into the spray arm holder 5000 and rotatably provided with respect to the spray arm holder 5000, so that when the spray arm 1000 sprays a water flow to be rotated, the rotation shaft 2000 is supported in the spray arm holder 5000, thereby enabling the rotation with respect to the spray arm holder 5000 by the rotation shaft 2000. The opposite sides of the rotating shaft 2000 are respectively provided with a buckle 1204, the spray arm seat 5000 is provided with an annular clamping boss 5100 along the circumferential direction of the spray arm seat 5000, and when the spray arm 1000 is communicated with the rotating shaft 2000 and is arranged on the spray arm seat 5000, the buckles 1204 are clamped with the annular clamping bosses 5100 to prevent the spray arm 1000 from being separated from the spray arm seat 5000 in the axial direction of the spray arm seat 5000 in the rotating process.

To control the flow direction of the water flow, this is achieved by a diverter 3000 and a stop 4000. The diverter 3000 is configured to receive the water flow from the spindle 2000 and then input the water flow to the spray arm 1000, and the diverter 3000 can rotate following the rotation of the spray arm 1000. Specifically, the diverter 3000 is provided with a flow channel 3001, an inlet 3115 communicating with the flow channel 3001, and an outlet 3220 communicating with the flow channel 3001, the rotation shaft 2000 is communicated with the inlet 3115, the outlet 3220 includes two outlets, which are defined as a first outlet 3221 and a second outlet 3222, the first outlet 3221 is communicated with the first flow channel 1300, the second outlet 3222 is communicated with the second flow channel 1400, water flow enters the flow channel 3001 from the inlet 3115, if the water flow is output from the first outlet 3221, the water flow can be input into the first flow channel 1300, so that the water flow can be emitted from the first nozzle 1101, and the clockwise rotation of the spray arm 1000 is realized; if a water flow is output from the second outlet 3222, the water flow may be input into the second flow channel 1400 such that the water flow is emitted from the second nozzle 1102, and the counterclockwise rotation of the spray arm 1000 is achieved. The control of the water flow is achieved by providing a stopper 4000 in the flow channel 3001, in particular, the stopper 4000 is movably provided in the flow channel 3001, and the stopper 4000 is provided to switchably block one of the first outlet 3221 and the second outlet 3222 under the action of the water flow, so that the spray arm 1000 can be controlled to rotate clockwise or counterclockwise.

For example, when the boom seat 5000 is not being supplied with water, the stopper 4000 is in a stationary state in the flow channel 3001, when water is being supplied with water, the water enters the flow channel 3001 from the inlet 3115, the water impacts the stopper 4000, the stopper 4000 seals the first outlet 3221 by the impact of the water and the buoyancy of the water, and when the water is disconnected, the stopper 4000 leaves the first outlet 3221 due to the lack of impact and buoyancy of the water. When water again enters the flow channel 3001 from the inlet 3115, the stopper 4000 seals the second outlet 3222 by the water, and when the water is disconnected, the stopper leaves the second outlet 3222. The first outlet 3221 and the second outlet 3222 can be plugged in a switchable manner by repeating the steps, the blocking piece 4000 can be in a sphere shape, and the outlet 3220 is a round hole and is smaller than the blocking piece 4000 in size, so that the plugging can be effectively realized.

Taking the operation of the dishwasher as an example, when the washing sequence starts, the washing pump sucks the water in the washing cavity and delivers the water to the spray arm seat 5000, and then the water is input to the runner 3001 from the inlet 3115 through the rotating shaft 2000, the blocking member 4000 seals the first outlet 3221 under the action of the water flow, so that the water flow flows out from the second outlet 3222 and is input to the second runner 1400, and finally is sprayed out from the second nozzle 1102, and at this time, the spray arm 1000 can rotate anticlockwise. In order to switch the rotation direction of the spray arm 1000, the time for switching off the washing pump and the time for restarting the washing pump are preset in the dishwasher, and the dishwasher controls the washing pump to stop, so that the water flow is disconnected, and the blocking member 4000 leaves the first outlet 3221 under the effect of losing the water flow. The dishwasher controls the washing pump to be started again, water is input into the runner 3001 again, the blocking piece 4000 seals the second outlet 3222 under the action of the water flow, namely the water flow flows out of the first outlet 3221 and is input into the first runner 1300, and finally is sprayed out of the first nozzle 1101, and at the moment, the spray arm 1000 can rotate clockwise. Through such scheme, can realize two kinds of rotation direction in same spray arm 1000, improved the washing effect, the fender 4000 only need can control the flow direction of rivers through the effect of rivers moreover, need not use other electronic components, and is reliable and stable.

It can be understood that the baffle 4000 controls the rotation direction of the spray arm 1000 through the on-off of water flow, and the on-off of water flow can be realized through the start and stop of the washing pump, or a water diversion valve can be arranged in the waterway, so that the water flow flowing into the spray arm seat 5000 can be temporarily cut off, and the on-off of water flow can be realized.

As shown in fig. 9 and 12, in some embodiments, the flow channel 3001 has a second wall surface 3210 and a first wall surface 3110, the second wall surface 3210 is disposed above the first wall surface 3110, such an upper side may be a right upper side or an inclined upper side, the outlets 3220 (the first outlet 3221 and the second outlet 3222) are disposed on the second wall surface 3210, so when the baffle 4000 is impacted by the water flow to block the first outlet 3221 or the second outlet 3222, since the water flow is continuously introduced into the flow channel 3001, that is, the flow channel 3001 is filled with water, the baffle 4000 continuously blocks the first outlet 3221 or the second outlet 3222 under the action of the buoyancy of the water flow and does not leave the outlets 3220 (the first outlet 3221 and the second outlet 3222) along with the introduction of the water flow, and only when the water flow is disconnected, the baffle 4000 can leave the outlets 3220 (the first outlet 3221 and the second outlet 3222) under the action of gravity.

The first wall 3110 is disposed below the second wall 3210, and has a receiving space formed therein for receiving the stopper 4000, for example, the receiving space is formed as a concave surface, and the stopper 4000 is positioned when moved to the concave surface, but is simultaneously moved by being flushed by water flow. The two accommodation positions are defined as a second accommodation position 3112 and a first accommodation position 3111, the baffle 4000 can move to the second accommodation position 3112 or the first accommodation position 3111 under the action of water flow, when the baffle 4000 is in the first accommodation position 3111, the baffle 4000 can leave the first accommodation position 3111 under the action of impact and buoyancy of the water flow to seal one of the outlets 3220, such as the first outlet 3221, when the water flow flows out through the second outlet 3222; when the stopper 4000 is at the second receiving position 3112, the stopper 4000 can be moved away from the second receiving position 3112 by impact and buoyancy of the water flow to block the other outlet 3220, for example, the second outlet 3222, and the water flow flows out through the first outlet 3221. By designing the blocking member 4000 to be switchably disposed at the first receiving position 3111 and the second receiving position 3112 under the action of the water flow, the control of the flow direction of the water flow can be achieved.

For example, as shown in connection with fig. 11, in some embodiments, the baffle 4000 may fall back from one of the outlets 3220 to the second receiving location 3112 and from the other outlet 3220 to the first receiving location 3111 when the impact and buoyancy of the water flow is lost, where "one of the outlets 3220" is the first outlet 3221 described above and "the other outlet 3220" is the second outlet 3222 described above, the baffle 4000 leaving the first receiving location 3111 to block the first outlet 3221 under the effect of the water flow, and the baffle 4000 may not fall back to the first receiving location 3111 but to the second receiving location 3112 when the baffle 4000 loses the effect of the water flow; the stopper 4000 leaves the second receiving position 3112 to block the second outlet 3222 by the water flow, and the stopper 4000 does not fall back to the second receiving position 3112 but to the first receiving position 3111 when the stopper 4000 loses the water flow. That is, the moving path of the blocking member 4000 is a closed loop, if the initial position of the blocking member 4000 is at the first receiving position 3111, the blocking member 4000 blocks the first outlet 3221 when receiving the water flow, and drops back to the second receiving position 3112 when losing the water flow, the blocking member 4000 blocks the second outlet 3222 when receiving the water flow at the second receiving position 3112, and drops back to the first receiving position 3111 when losing the water flow, and the cycle is thus repeated.

By designing the path of movement of the shutter 4000 as a loop, it is achieved that the shutter 4000 switchably blocks one of the two outlets 3220, and this design can be reduced in volume and more easily matched to the installation of the spray arm 1000.

As shown in connection with fig. 11, in some embodiments, the first wall 3110 is provided with a lower guide 3300, e.g., the lower guide 3300 is directly formed on the first wall 3110, and the lower guide 3300 is used for guiding the baffle 4000 to block the corresponding outlet 3220 under the action of the water flow. For example, a lower guide portion 3300 is provided on a path from the first accommodating position 3111 to the second accommodating position 3112, the stopper 4000 being movable along a path, the lower guide portion 3300 being defined as a first lower guide portion 3310, the stopper 4000 being separated from the first accommodating position 3111 by being subjected to a water flow when in the first accommodating position 3111, the stopper 4000 being moved toward the first outlet 3221 by the first lower guide portion 3310 to block the first outlet 3221 during separation from the first accommodating position 3111. A lower guide 3300 is also provided on the path of the second receiving location 3112 to the first receiving location 3111, defining the lower guide 3300 as a second lower guide 3320, and by providing the second lower guide 3320, the stopper 4000 is separated from the second receiving location 3112 by being acted upon by the water flow when in the second receiving location 3112, and touches the second lower guide 3320 during separation from the second receiving location 3112, and the second lower guide 3320 moves the guide stopper 4000 toward the second outlet 3222 to block the second outlet 3222.

Further, as shown in fig. 11, in some embodiments, the lower guide 3300 may also be used to guide the fall back of the flight 4000 when the flight 4000 loses the action of the fluid, so that the fall back of the flight 4000 is smoother. For example, as the first lower guide portion 3310 and the second lower guide portion 3320 described above, when the stopper 4000 is in a state of blocking the first outlet 3221, the water flow is disconnected, the stopper 4000 touches the first lower guide portion 3310 in the process of falling back by gravity, and the first lower guide portion 3310 guides the stopper 4000 to the second accommodation position 3112; when the blocking member 4000 is in a state of blocking the second outlet 3222, the water flow is disconnected, and the blocking member 4000 touches the second lower guide portion 3320 in the process of falling back under the action of gravity, and the second lower guide portion 3320 guides the blocking member 4000 to the first receiving position 3111. Through designing lower guide 3300 to also play the effect of guiding the whereabouts of stopper 4000 for the whereabouts of stopper 4000 removes more smoothly, makes simultaneously that stopper 4000 can reach corresponding position in advance before next limp-time, thereby makes stopper 4000 shutoff corresponding export 3220 more fast when limp-time, makes the control efficiency to rivers higher.

Specifically, the lower guide 3300 guides the stopper 4000 by the following scheme. As shown in fig. 11, in some embodiments, the lower guide portion 3300 is provided with a first guide surface 3301, and the stopper 4000 can touch the first guide surface 3301 when moving, the first guide surface 3301 being inclined to extend toward the second wall surface 3210 along the moving direction of the stopper 4000, so that the first guide surface 3301 guides the stopper 4000 to the corresponding outlet 3220. The first lower guide 3310 and the second lower guide 3320 are described. The first lower guide portion 3310 is provided with a first guide surface 3301, the first guide surface 3301 of the first lower guide portion 3310 extends from the first accommodating position 3111 to the second accommodating position 3112, the direction of the first accommodating position 3111 to the second accommodating position 3112 is the moving direction of the stopper 4000, and the first guide surface 3301 of the first lower guide portion 3310 is inclined toward the second wall surface 3210, so that the stopper 4000 can be guided to the first outlet 3221 by the first guide surface 3301 of the first lower guide portion 3310 when being impacted by water flow. The same is true for the second lower guide portion 3320, the first guide surface 3301 of the second lower guide portion 3320 extends from the second accommodating position 3112 to the first accommodating position 3111, the direction from the second accommodating position 3112 to the first accommodating position 3111 is the moving direction of the stopper 4000, and the first guide surface 3301 of the second lower guide portion 3320 is inclined toward the second wall surface 3210, so that the stopper 4000 can be guided to the second outlet 3222 by the first guide surface 3301 of the second lower guide portion 3320 when being impacted by water flow.

Further, as shown in fig. 11, in some embodiments, in order to achieve a certain guiding effect on the falling back of the stopper 4000, the lower guiding portion 3300 is provided with a second guiding surface 3302, the second guiding surface 3302 is connected with the first guiding surface 3301, and the second guiding surface 3302 extends obliquely from the first guiding surface 3301 toward the first wall 3110 along the moving direction of the stopper 4000, that is, the first guiding surface 3301 and the second guiding surface 3302 together form a sharp corner toward the second wall 3210. The first lower guide 3310 and the second lower guide 3320 are described. The first lower guide portion 3310 is further provided with a second guide surface 3302, the second guide surface 3302 of the first lower guide portion 3310 extends from the first guide surface 3301 of the first lower guide portion 3310 in the direction from the first accommodating position 3111 to the second accommodating position 3112 and is inclined toward the first wall surface 3110, so that when the stopper 4000 loses the action of the water flow, it touches the second guide surface 3302 of the first lower guide portion 3310 during falling back, the second guide surface 3302 of the first lower guide portion 3310 guides the stopper 4000 to the second accommodating position 3112, that is, the first guide surface 3301 of the first lower guide portion 3310 and the first accommodating position 3111 meet, and the second guide surface 3302 of the first lower guide portion 3310 and the second accommodating position 3112 meet.

The second lower guide portion 3320 is also provided with a second guide surface 3302, the second guide surface 3302 of the second lower guide portion 3320 extends from the first guide surface 3301 of the second lower guide portion 3320 in the direction from the second accommodating position 3112 to the first accommodating position 3111 and is inclined toward the first wall surface 3110, so that when the stopper 4000 loses the effect of the water flow, it touches the second guide surface 3302 of the second lower guide portion 3320 during falling back, the second guide surface 3302 of the second lower guide portion 3320 guides the stopper 4000 to the first accommodating position 3111, that is, the first guide surface 3301 of the second lower guide portion 3320 is in contact with the second accommodating position 3112, and the second guide surface 3302 of the second lower guide portion 3320 is in contact with the first accommodating position 3111.

In some embodiments, the juncture of the second guide surface 3302 and the first guide surface 3301 forms a highest point relative to the first wall surface 3110, which corresponds to the outlet 3220, where the correspondence is downward in the height direction, e.g., in the top view of fig. 6, within the confines of the outlet 3220, which further facilitates guiding the flight 4000 to the corresponding outlet 3220. For example, the first lower guide portion 3310 and the first outlet 3221 are taken as examples, and the second lower guide portion 3320 and the second outlet 3222 have the same principle, and the description thereof will not be repeated. The junction between the second guide surface 3302 of the first lower guide portion 3310 and the first guide surface 3301 is located within the range enclosed by the first outlet 3221, so that when the stopper 4000 is guided by the first guide surface 3301 of the first lower guide portion 3310, the stopper is more quickly aligned with the first outlet 3221, thereby blocking the first outlet 3221.

In some embodiments, as shown in connection with fig. 6 and 11, to avoid reverse movement of the flight 4000 as it falls back out of the action of the water flow, this is accomplished by locating the junction of the second guide surface 3302 and the first guide surface 3301 upstream of the axis of the outlet 3220. Specifically, the first lower guide portion 3310 and the first outlet 3221 are taken as examples, and the second lower guide portion 3320 and the second outlet 3222 have the same principle, and the description thereof will not be repeated. When water flows from the inlet 3115 into the flow channel 3001, the water flows from the first receiving space 3111 toward the second receiving space 3112 and over the first outlet 3221, so that the axis of the first outlet 3221 is upstream toward the first receiving space 3111 and downstream toward the second receiving space 3112 for the first outlet 3221, and after the stopper 4000 is impacted by the water flow to block the first outlet 3221, the stopper 4000 can more reliably contact the second guide surface 3302 of the first lower guide 3310 when the stopper falls back due to the loss of the water flow, thereby guiding the water flow to the second receiving space 3112. In other embodiments, the junction may not be located upstream of the axis, and thus, an improvement in the first outlet 3221 may be required, i.e., the stopper 4000 may require a corresponding movement when contacting the second wall 3210 to block the first outlet 3221, thereby avoiding a reverse movement when touching the junction when falling back. The arrangement of the junction upstream of the axis makes the whole construction simpler and more reliable.

In some embodiments, as shown in conjunction with fig. 8, in the height direction, the connection between the second guiding surface 3302 and the first guiding surface 3301 forms the highest point, the connection is separated from the corresponding outlet 3220 by a distance L1, and the dimension of the baffle 4000 in the height direction is L2, so that L1 is greater than L2, so that the corresponding outlet 3220 is plugged after the baffle is separated from the guiding of the lower guiding portion 3300, or the baffle touches the corresponding lower guiding portion 3300 after the baffle leaves the outlet 3220. Specifically, the first lower guide portion 3310 and the first outlet 3221 are taken as examples, and the second lower guide portion 3320 and the second outlet 3222 have the same principle, and the description thereof will not be repeated. The second guiding surface 3302 of the first lower guiding portion 3310 forms the highest point at the junction with the first guiding surface 3301, and the junction is opposite to the first outlet 3221, the distance between the junction and the first outlet 3221 is L1, the size of the baffle 4000 is L2, and since L1 is larger than L2, when the baffle 4000 is guided by the first guiding surface 3301 of the first lower guiding portion 3310 due to the impact of water flow, the baffle 4000 is separated from the first guiding surface 3301 of the first lower guiding portion 3310 to seal the first outlet 3221. Of course, in other embodiments, L1 may be not greater than L2, so that when the blocking member 4000 blocks the first outlet 3221, the blocking member 4000 needs to be correspondingly moved in cooperation with the first outlet 3221, that is, the blocking member 4000 needs to be correspondingly moved when touching the second wall surface 3210 to block the first outlet 3221, so that the blocking member cannot be blocked by the connection portion, and the whole structure is simpler and more reliable by satisfying that L1 is greater than L2.

With continued reference to fig. 9-11, in some embodiments, the slope of second guide surface 3302 is less than the slope of first guide surface 3301. Specifically, the first lower guide portion 3310 and the first outlet 3221 are taken as examples, and the second lower guide portion 3320 and the second outlet 3222 have the same principle, and the description thereof will not be repeated. When the stopper 4000 is in the first receiving position 3111 and is impacted by the water flow, since the slope of the first guide surface 3301 of the first lower guide 3310 is relatively large, the first guide surface 3301 of the first lower guide 3310 can change the moving direction of the stopper 4000 more quickly when the stopper 4000 touches the first guide surface 3301 of the first lower guide 3310, so that the stopper 4000 blocks the first outlet 3221 more quickly. Of course, in other embodiments, the slope of the first guide surface 3301 of the first lower guide portion 3310 may be equal to the second guide surface 3302, but thus the buffer effect is relatively weakened when the stopper 4000 touches the second guide surface 3302 of the first lower guide portion 3310 when falling back, and the impact of the falling stopper 4000 can be buffered by the second guide surface 3302 of the first lower guide portion 3310 having a smaller slope so that it reaches the second receiving position 3112 more smoothly.

With continued reference to fig. 9-11, in some embodiments, the extension of the second guide surface 3302 is greater than the extension of the first guide surface 3301. Specifically, the first lower guide portion 3310 and the first outlet 3221 are taken as examples, and the second lower guide portion 3320 and the second outlet 3222 have the same principle, and the description thereof will not be repeated. When the first guide surface 3301 of the first lower guide portion 3310 is provided on the first wall surface 3110 with a different extension length from the second guide surface 3302, the first guide surface 3301 of the first lower guide portion 3310 may be inclined more than the second guide surface 3302 of the first lower guide portion 3310 while ensuring a smoother transition of the first wall surface 3110, and the smoother transition of the first wall surface 3110 may prevent abrupt changes in the height direction, thereby blocking water flow.

As shown in fig. 10, in some embodiments, the first wall 3110 is provided with two flow sections, namely a first flow section 3113 and a second flow section 3114, the first flow section 3113 is disposed on a path from the first accommodation site 3111 toward the second accommodation site 3112, the second flow section 3114 is disposed on a path from the second accommodation site 3112 toward the first accommodation site 3111, and the first accommodation site 3111 is located in a water flow entering direction of the inlet 3115.

In this manner, the first lower guide portion 3310 is disposed at the first flow section 3113, the second lower guide portion 3320 is disposed at the second flow section 3114, and if the stopper 4000 is initially positioned at the first receiving position 3111, the stopper 4000 can sequentially reach the first outlet 3221, the second receiving position 3112, the second outlet 3222, the first receiving position 3111 (such direction is defined as a first direction), that is, the stopper 4000 moves substantially along the river-closed loop, and the first receiving position 3111 is positioned in the direction of the water flow at the inlet 3115, so that the water flow can be promoted to fill the entire flow channel 3001 along the first receiving position 3111, the first flow section 3113 (the first lower guide portion 3310), the second receiving position 3112, the second flow section 3114 (the second lower guide portion 3320), and the direction of the first receiving position 3111 under the effect of the water flow, and the stopper 4000 can be promoted to move circularly along the direction, thereby preventing the movement of the stopper 4000 caused by the movement in the reverse direction when the water flow is introduced from the inlet 3115.

In the height direction, the first flow section 3113 is gradually raised and the second flow section 3114 is gradually lowered in the height direction, further urging the flight 4000 to move in the first direction by the gradual design of the first flow section 3113 and the second flow section 3114.

Further, in some embodiments, first receiving location 3111, first flow section 3113, second receiving location 3112, and second flow section 3114 are end-to-end. The first flow section 3113 is disposed between the first accommodating position 3111 and the second accommodating position 3112, the first flow section 3113 is provided with a first lower guide portion 3310, a first guide surface 3301 of the first lower guide portion 3310 is connected to the first accommodating position 3111, a second guide surface 3302 of the first lower guide portion 3310 is connected to the second accommodating position 3112, the second flow section 3114 is disposed between the second accommodating position 3112 and the first accommodating position 3111 and is disposed alternately with the first flow section 3113, the second accommodating position 3112 is provided with a second lower guide portion 3320, the first guide surface 3301 of the second lower guide portion 3320 is connected to the second accommodating position 3112, and the second guide surface 3302 of the second lower guide portion 3320 is connected to the first accommodating position 3111, so that the first wall surface 3110 forms an annular passage.

The annular passage, for example, the annular passage, can reduce the resistance to the water flow channel 3001 to avoid affecting the water pressure, and the annular passage can simplify the movement of the baffle 4000 and reduce the structural complexity. The whole flow channel 3001 is also designed into an annular passage in cooperation with the first wall surface 3110, so that the water flow can flow along the first direction conveniently, turbulence is avoided, the stability of the water flow is improved, and energy waste is avoided.

Still further, in some embodiments, the first receiving location 3111 is disposed tangentially to the water flow entering the inlet 3115, such that blocking of the water flow to increase resistance to the water flow is avoided when the water flow enters through the inlet 3115, and further ensuring that the stop 4000 is movable in the first direction.

Further, in order to better guide the stopper 4000, referring to fig. 9 to 11, the lower guide portion 3300 forms a double rail structure, i.e., a double-layered alternate structure. Taking the first guide surface 3301 of the first lower guide portion 3310 as an example, two first guide surfaces 3301 of the first lower guide portion 3310 are provided alternately in the radial direction of the flow splitter 3000, so that the guide of the stopper 4000 is smoother.

As shown in fig. 1, 2, 5, 9 and 12, the diverter 3000 is disposed on one side of the rotating shaft 2000, that is, beside the rotation axis of the spray arm 1000, and the rotation axis of the spray arm 1000 is not coaxial, for example, the diverter 3000 is fixed on one side of the rotating shaft 2000, or the diverter 3000 is fixed on the spray arm 1000, or the diverter 3000 is fixed on the rotating shaft 2000 and the diverter 3000, so that the diverter 3000 can rotate along with the rotation of the spray arm 1000, but the rotation of the rotating shaft 2000 relative to the spray arm seat 5000 is not hindered, thereby ensuring the rotatable arrangement of the spray arm 1000 and controlling the water flow.

Further, the other side of the rotating shaft 2000 is provided with a balancing weight, and the balancing weight can be directly fixed on the other side of the rotating shaft 2000 and symmetrically arranged with the shunt 3000; or the balancing weight is fixed on the lower piece 1200 of the spray arm and symmetrically arranged with the diverter 3000; or the balancing weight is fixed on the lower spray arm piece 1200 and the rotating shaft 2000, and is symmetrically arranged with the diverter 3000. Thus, the problem of rotation eccentricity caused by the arrangement of the diverter 3000 can be balanced, and the rotation blockage or water leakage caused by the eccentricity of the spray arm 1000 can be prevented, so that the rotation is smoother. The balancing weight can be arranged according to actual conditions, for example, the balancing weight is of a solid block structure or a hollow structure.

As shown in connection with fig. 9 and 12, in some embodiments, the spray arm 1000 is provided with a first input port 1201 and a second input port 1202, and the sprayer further includes a housing 3100, where the housing 3100 is connected to the spray arm 1000 and covers the second input port 1202 and the first input port 1201, so that the splitter 3000 is formed, and the structure is simplified by combining the housing 3100 with the spray arm 1000 to form the splitter 3000.

Specifically, the splitter 3000 may be a separate structure and then communicate with the spray arm 1000 through a corresponding interface, but this connection is somewhat cumbersome. The first input port 1201 and the second input port 1202 are disposed on the boom lower plate 1200, the first input port 1201 forms one of the outlets 3220, i.e. the first outlet 3221, the second input port 1202 forms the other outlet 3220, i.e. the second outlet 3222, and the housing 3100 and the boom lower plate 1200 are connected to cover the first input port 1201 and the second input port 1202, so as to form the diverter 3000, thereby simplifying the structure and facilitating the water flow to be input into the first flow channel 1300 and the second flow channel 1400. The housing 3100 and the boom lower plate 1200 may be connected by welding, for example, and the flow path 3001 may be formed by welding the housing 3100 and the boom lower plate 1200 when the stopper 4000 is placed in the housing 3100.

Further, the housing 3100 and the rotating shaft 2000 are integrally formed, so that the manufacturing is convenient, and the structural strength is enhanced. The housing 3100 is provided with an inlet 3115 in communication with the shaft 2000 for receiving water flow from the boom seat 5000.

The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the scope of the claims, and all equivalent structural changes made in the present application and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the present application.
