The embodiment of the application provides a treatment agent delivery device, as shown in fig. 1 to 4, which comprises a first chamber 1A, a rotating mechanism 2 and a delivery mechanism, wherein the first chamber 1A is provided with a first water inlet 1011 and a second water inlet 1012, the rotating mechanism 2 is arranged in the first chamber 1A, the rotating mechanism 2 comprises a rotating body 21, a first blade group and a second blade group which are arranged on the rotating body 21 at intervals, the delivery mechanism is connected with the rotating body 21 and is used for delivering the treatment agent under the drive of the rotating body 21, water flow entering through the first water inlet 1011 is matched with the first blade group and is suitable for pushing the rotating body 21 to rotate along a first direction so as to control the delivery mechanism to deliver the first treatment agent, and water flow entering through the second water inlet 1012 is matched with the second blade group and is suitable for pushing the rotating body 21 to rotate along a second direction so as to control the delivery mechanism to deliver the second treatment agent.
It will be appreciated that the water flow entering through the first inlet 1011 cooperates with the first vane set to drive the rotor 21 to rotate clockwise, the water flow entering through the second inlet 1012 cooperates with the second vane set to drive the rotor 21 to rotate counterclockwise, or the water flow entering through the first inlet 1011 cooperates with the first vane set to drive the rotor 21 to rotate counterclockwise, and the water flow entering through the second inlet 1012 cooperates with the second vane set to drive the rotor 21 to rotate clockwise. Therefore, one rotating mechanism 2 can drive the throwing mechanism to throw different treating agents under the action of water flow, the structure is simplified, the arrangement space is saved, and an electric driving device can be omitted, so that the cost is saved.
In some embodiments, the first chamber 1A further comprises an outlet 1013, the first inlet 1011 and the second inlet 1012 being located on a first side of the first chamber 1A, the outlet 1013 being located on a second side of the first chamber 1A, the second side being disposed opposite to the first side or being disposed perpendicular to each other. The rotator 21 is driven to rotate in a first direction if water flows in from the first water inlet 1011 and out from the water outlet 1013, and the rotator 21 is driven to rotate in a second direction if water flows in from the second water inlet 1012 and out from the water outlet 1013.
Illustratively, the first water inlet 1011 and the second water inlet 1012 are positioned on a first side of the housing 1, and the water outlet 1013 is positioned on a second side of the housing 1 opposite the first side, and the rotator 21 is driven to rotate in a first direction (counterclockwise as viewed in FIG. 3) if water flows in from the first water inlet 1011 and out from the water outlet 1013, and the rotator 21 is driven to rotate in a second direction (clockwise as viewed in FIG. 4) if water flows in from the second water inlet 1012 and out from the water outlet 1013. It will be appreciated that if the water flows into the first inlet 1011 and the second inlet 1012 at similar rates, the power of the rotor 21 will cancel each other, i.e. will remain stationary, but the water will flow out of the outlet 1013 normally. Thus, by controlling the water supply states of the first water inlet 1011 and the second water inlet 1012, the switching of the clockwise rotation, counterclockwise rotation, and stationary state of the rotator 21 can be achieved under the condition that the first chamber 1A normally supplies water. In practical application, the first water inlet 1011 and the second water inlet 1012 can be communicated with a water supply channel through the electromagnetic valve, and the rotation state of the rotator 21 can be effectively controlled by controlling the water supply state of the first water inlet 1011 and the second water inlet 1012 through the electromagnetic valve.
It is to be understood that the number of the water outlets 1013 may be plural, and those skilled in the art may reasonably set according to the needs, which is not limited herein.
It will be appreciated that the location of the water outlet 1013 can be appropriately set by those skilled in the art according to the requirements, and is not limited herein. For example, the plane of the water outlet 1013 may be perpendicular to the plane of the first water inlet 1011 and the second water inlet 1012, or may be opposite to the plane of the first water inlet 1011.
In some embodiments, as shown in fig. 1,3 and 4, the first chamber 1A is formed into a substantially cylindrical chamber, the first side of the first chamber 1A extends outwards to form a first water inlet pipe 1020 and a second water inlet pipe 1021, the first water inlet pipe 1020 and the second water inlet pipe 1021 are arranged in parallel and are respectively located at the upper end and the lower end of the first chamber 1A, the second side of the first chamber 1A extends outwards to form a water outlet pipe 1022, and the water outlet pipe 1022 is located at the middle of the first chamber 1A.
Illustratively, a first water inlet 1011 is formed at the inlet of the first water inlet pipe 1020, a second water inlet 1012 is formed at the inlet of the second water inlet pipe 1021, and a water outlet 1013 is formed at the outlet of the water outlet pipe 1022, wherein the water flows in from the first water inlet 1011 to drive the rotation mechanism 2 to rotate in the first direction, and the water flows in from the second water inlet 1012 to drive the rotation mechanism 2 to rotate in the second direction.
In some embodiments, as shown in fig. 2, the rotation mechanism 2 further includes a baffle 24, where the baffle 24 is located between the first blade set and the second blade set, for separating the first blade set from the second blade set. As shown in fig. 2, the first blade group includes a plurality of first blades 22, the plurality of first blades 22 being located on the upper side of the baffle 24, and the plurality of first blades 22 being disposed along the circumferential direction of the rotor 21. The second blade group includes a plurality of second blades 23, which are located at the lower side of the baffle 24, and a plurality of second blades 22, which are disposed along the circumferential direction of the rotor 21. Here, the first blade 22 and/or the second blade 23 may be curved blades or straight blades, where the straight blades refer to the surfaces of the blades that are planar to rotate under the driving of the water flow, and the curved blades refer to the surfaces of the blades that are curved, so that the blades have a set radian, which is beneficial to forming a rotating vortex, thereby improving the rotation efficiency.
In some embodiments, the first blade 22 and the second blade 23 are both curved blades, the curved curvature of the first blade being in the opposite direction of the curved curvature of the second blade. As shown in fig. 3 and 4, the first vane 22 is bent in a clockwise direction, so that the water flow entering through the first water inlet 1011 applies a counterclockwise pressure to the first vane 22, thereby driving the rotator 21 to rotate counterclockwise. The second vane 23 is bent in a counterclockwise direction, so that the water flow entering through the second water inlet 1012 applies a clockwise pressure to the second vane 23, thereby driving the rotator 21 to rotate in a clockwise direction. Thus, the double-sided blades of one impeller (namely the rotating mechanism 2) can be utilized to efficiently rotate forward or backward under the action of water flow, so that different treating agents can be respectively thrown in by the throwing mechanism driven by the rotating body 21.
It will be appreciated that the baffle 24 is located between the first blade set and the second blade set for separating the first blade 22 from the second blade 23, reducing the likelihood of water flow entering the first inlet 1011 acting on the second blade set and reducing the likelihood of water flow entering the second inlet 1012 acting on the first blade set, improving the efficiency of the hydrodynamic conversion.
In some embodiments, the center of the rotor 21 is provided with a spindle connection hole structure 211, and the input shaft of the throwing mechanism may be matched with the spindle connection hole structure 211 on the rotor 21, so as to transmit the power of the rotor 211 to the throwing mechanism.
In some embodiments, the rotating body 21 is provided with a plurality of through holes 212, and by forming the through holes 212, the self weight of the rotating body 21 can be reduced, so that the rotating body 21 can be driven to rotate by water flow. In addition, the through holes 212 can prevent the interference of the water retained in the rotor 21 to the rotation of the rotor 21, thereby further improving the rotation efficiency of the rotor 21.
In some embodiments, the first blade set, the second blade set, the rotor 21 and the baffle 24 are integrally formed, so that the rotating mechanism 2 is of a unitary structure, and the assembly process is simplified. In other embodiments, the rotating mechanism 2 may be assembled by a split structure.
In some embodiments, as shown in FIG. 1, the dispensing mechanism includes a second chamber 1C, a reduction mechanism 3, a power distribution mechanism 4, and a dispensing mechanism. Wherein the second chamber 1C has a first inlet 1016 and a second inlet 1018. The speed reducing mechanism 3 is connected with the rotating mechanism 2 and is used for reducing the speed and increasing the torque of the power output by the rotating mechanism 2 and then outputting the power. The power distribution mechanism 4 is connected to the output end of the reduction mechanism 3, and the power distribution mechanism 4 has a first output end and a second output end for transmitting the power output from the reduction mechanism 3. The dispensing mechanism is disposed in the second chamber 1C, and the dispensing mechanism includes a first dispensing mechanism 5 and a second dispensing mechanism 6, where the first dispensing mechanism 5 is connected to the first output end for controlling the dispensing of the treating agent at the first liquid inlet 1016, and the second dispensing mechanism 6 is connected to the second output end for controlling the dispensing of the treating agent at the second liquid inlet 1018.
Because the rotating mechanism 2 can be driven by water flowing into the first chamber 1A through the first water inlet 1011 or the second water inlet 1012, the power output by the rotating mechanism 2 is output to the power distribution mechanism 4 after being decelerated and torque-increased through the decelerating mechanism 3, the power distribution mechanism 4 drives the first distribution mechanism 5 to control the throwing of the treating agent at the first liquid inlet 1016 or drives the second distribution mechanism 6 to control the throwing of the treating agent at the second liquid inlet 1018, thus, the treating agent throwing device can utilize water flow as a power source to realize the automatic throwing of the treating agent, and an electric driving device can be omitted, thereby saving the cost. The treating agent may be a liquid or powder washing product required for washing, and those skilled in the art may appropriately select the treating agent according to the need, which is not particularly limited in the present application.
In addition, it should be noted that, in the embodiment of the present application, since the water pressure of the water flow fluctuates during the use process, the power output by the rotating mechanism 2 is reduced in speed and increased in torsion by the reducing mechanism 3 and then transmitted to the power distribution mechanism 4, so that the working range of the water flow water pressure can be effectively widened, after the rotating mechanism 2 is driven by the water flow in a low water pressure state, the reducing mechanism 3 reduces in speed and increased in torsion, so as to increase the torque output by the power distribution mechanism 4, so that the first distribution mechanism 5 or the second distribution mechanism 6 can effectively control the delivery of the treatment agent at the respective liquid inlet, thereby realizing the automatic delivery of the treatment agent, and since the first distribution mechanism 5 controls the delivery of the treatment agent at the first liquid inlet 1016 and the second distribution mechanism 6 controls the delivery of the treatment agent at the second liquid inlet, the classified automatic delivery of different types of the treatment agents can be realized, thereby further saving the control cost of the classified automatic delivery.

The first reduction gear 302 has a large end face engaged with the power shaft 301 and a small end face for engagement with the second reduction gear 303. The power shaft 301 may extend into the first chamber 1A and be connected to the rotating mechanism 2, and is driven by the rotating mechanism 2.

It will be appreciated that one end of the power shaft 301 may extend into the first chamber 1A and be fixedly connected to the rotating mechanism 2, and the other end of the power shaft 301 is provided with external teeth meshed with the planetary gear 305, as a sun gear of the planetary reducer. The carrier 306 has an end portion that outputs power, and the end portion is connected to an input end of the power distribution mechanism 4.
In some embodiments, the reduction ratio of the reduction mechanism 3 is 30-150:1. Therefore, the treating agent delivery device can normally work within the water pressure range of 0.03-1.0 MPa, so that the treating agent delivery device has a wide application prospect, and can be applied to household appliances such as washing machines or dish washers.
It will be appreciated that at least two of the reduction mechanism 3, the power distribution mechanism 4 and the dispensing mechanism described above are located in the same chamber. In some embodiments, the power distribution mechanism 4 may be disposed in the third chamber 1B, i.e. the fourth chamber 1D is omitted, and the third chamber 1B is located between the first chamber 1A and the second chamber 1C, so that the structure is compact, and the speed reducing mechanism 3 and the power distribution mechanism 4 are both located in the third chamber 1B, so that the appearance of the treatment agent delivery device is attractive. In some embodiments, the third chamber 1B and the fourth chamber 1D may be omitted such that the reduction mechanism 3 and the power distribution mechanism 4 are both disposed within the second chamber 1C.
Illustratively, the reduction mechanism 3, the power distribution mechanism 4, and the dispensing mechanism described above may each be located in separate chambers. As shown in fig. 1, a third chamber 1B accommodating the reduction mechanism 3 and a fourth chamber 1D accommodating the power distribution mechanism 4 are formed in the housing 101, and the third chamber 1B and the fourth chamber 1D are located between the first chamber 1A and the second chamber 1C.
As shown in fig. 8, the power distribution mechanism 4 comprises a driving wheel 401, a first ratchet shaft 402, a driven wheel 403 and a second ratchet shaft 404, wherein the driving wheel 401 is connected with an output end (such as an output shaft 304 shown in fig. 5 or a planet carrier 306 shown in fig. 6) of the reduction mechanism 3, a first ratchet 4011 is arranged on the inner wall surface of the driving wheel 401, the first ratchet shaft 402 is sleeved in the driving wheel 401 and can rotate in a unidirectional way in cooperation with the first ratchet 4011, the driven wheel 403 is meshed with the driving wheel 401 and connected, a second ratchet 4031 is arranged on the inner wall surface of the driven wheel 403, and the second ratchet shaft 404 is sleeved in the driven wheel 403 and can rotate in a unidirectional way in cooperation with the second ratchet 4031. The first ratchet shaft 402 forms a first output of the power distribution mechanism 4 and the second ratchet shaft 404 forms a second output of the power distribution mechanism 4. The driving wheel 401 and the driven wheel 403 are externally meshed, and the rotation directions of the two are opposite, and the unidirectional rotation direction of the first ratchet shaft 402 and the unidirectional rotation direction of the second ratchet shaft 404 are the same. For example, the first ratchet shaft 402 and the second ratchet shaft 404 are rotated clockwise, and when the driving wheel 401 is rotated clockwise, the first ratchet shaft 402 is rotated clockwise by the driving of the first ratchet 4011, the driven wheel 403 is rotated counterclockwise, the second ratchet shaft 404 is in slip fit with the second ratchet 4031, and when the driving wheel is rotated counterclockwise, the first ratchet shaft 402 is in slip fit with the first ratchet 4011, the driven wheel 403 is rotated clockwise, and the second ratchet shaft 404 is rotated clockwise by the driving of the second ratchet 4031.
It will be appreciated that the driving wheel 401 is connected to the output end of the reduction mechanism 3, i.e. to the output shaft 304 shown in fig. 5 or the end of the planet carrier 306 shown in fig. 6, to rotate under the power transmitted by the reduction mechanism 3. The driving wheel 401 and the first ratchet shaft 402 form a first ratchet assembly, the driven wheel 403 and the second ratchet shaft 404 form a second ratchet assembly, specifically, the outer wall surface of the first ratchet shaft 402 is provided with an elastic pawl matched with the first ratchet 4011, the first ratchet shaft 402 can only rotate unidirectionally through the matching of the pawl and the first ratchet 4011, and similarly, the outer wall surface of the second ratchet shaft 404 is provided with an elastic pawl matched with the second ratchet 4031, and the second ratchet shaft 404 can only rotate unidirectionally through the matching of the pawl and the second ratchet 4031. Since the driving wheel 401 is engaged with the driven wheel 403, for example, by a tooth or pin external engagement, the driving wheel 401 and the driven wheel 403 are rotated in opposite directions. As shown in fig. 8, the case where the ratchet shaft and the ratchet teeth slip in the counterclockwise direction and rotate in the clockwise direction is taken as an example, when the driving wheel 401 rotates in the clockwise direction by the driving of the reduction mechanism 3, the driven wheel 403 rotates in the counterclockwise direction, and at this time, the first ratchet shaft 402 is pushed by the first ratchet 4011 of the driving wheel 401 to rotate in the clockwise direction, but the second ratchet shaft 404 rotates in the counterclockwise direction by the driven wheel 403, so that the second ratchet shaft is in a slipping state and does not transmit torque. When the driving wheel 401 rotates anticlockwise under the drive of the speed reducing mechanism 3, the driven wheel 403 rotates clockwise, at this time, the first ratchet shaft 402 is in a slipping state and does not transmit torque, but the second ratchet shaft 404 rotates clockwise due to the driven wheel 403, and the second ratchet shaft 4042 rotates clockwise under the pushing of the second ratchet 4031 of the driven wheel 403 and outputs torque. In this way it is achieved that when the output shaft 304 rotates clockwise power is distributed to the first ratchet shaft 402 and when the output shaft 304 rotates counter-clockwise power is distributed to the second ratchet shaft 404.
