In the present embodiment, the water pump device 10 includes: a housing 11, a drive mechanism 12, an impeller 13, and a gear mechanism 14.

The water pump device 10 provided by the utility model can be particularly applied to an intelligent toilet bowl, so as to be communicated with a water storage mechanism of the intelligent toilet bowl, and liquid stored in the water storage mechanism is introduced and directionally discharged, so that pollution discharge flushing or human body cleaning can be effectively realized. Of course, in other embodiments, the water pump device 10 may be used in a spraying system, or any other reasonable mechanical device such as a liquid medicine spraying device in a production system, which is not limited in this embodiment.

Specifically, a housing 11 in the water pump device 10 is internally formed with a receiving cavity, and a first water inlet 1101, a first water outlet 1102, a second water inlet 1103 and a second water outlet 1104 are provided on a side wall of the housing 11 at intervals.

The first water inlet 1101 and the second water inlet 1103 are used for communicating with an external water storage mechanism, so that the liquid stored in the water storage mechanism can flow into the accommodating cavity in the housing 11 from the first water inlet 1101 and the second water inlet 1103.

Further, the driving mechanism 12 is disposed in a receiving cavity inside the housing 11, and divides the receiving cavity into a first cavity 101 and a second cavity 102 that are not communicated; the first water inlet 1101 and the first water outlet 1102 on the side wall of the housing 11 are specifically and alternately connected to the first cavity 101, and the second water inlet 1103 and the second water outlet 1104 on the side wall of the housing 11 are specifically and alternately connected to the second cavity 102.

It can be appreciated that, when the driving mechanism 12 is in the first working state, the driving mechanism 12 may specifically drive the impeller 13 to rotate, so that when the liquid stored in the water storage mechanism flows into the first cavity 101 in the housing 11 from the first water inlet 1101, the liquid can be driven to be discharged from the first water outlet 1102 by means of the rotation of the impeller 13; in the second operating state of the driving mechanism 12, the driving mechanism 12 may specifically be that the driving gear mechanism 14 adjusts the internal volume of the second cavity 102 inside the housing 11, for example, the internal volume of the second cavity 102 is gradually increased and then gradually decreased by adjusting the meshing state of the gear mechanism 14, so as to continuously discharge the liquid flowing into the second cavity 102 from the second water outlet 1104.

In the above scheme, the driving control of two paths of water is effectively realized through a group of driving mechanisms 12, so that different service purposes can be respectively provided, for example, when the water pump device 10 is applied to an intelligent toilet, the driving control of the impeller 13 and the gear mechanism 14 can be respectively carried out, so that the liquid stored in the water storage mechanism flows into the first cavity 101 in the shell 11 from the first water inlet 1101, is discharged from the first water outlet 1102, or flows into the second cavity 102 in the shell 11 from the second water inlet 1103, and is discharged from the second water outlet 1104, so that the functions of pollution discharge flushing and human body cleaning are respectively carried out, the water is prevented from being taken directly from a tap water pipe, and the parts such as various electromagnetic valves, ball valves, pressure reducing valves, vacuum destructors and the like are respectively connected to the rear end of each waterway, and the water pump device 10 effectively simplifies the whole part configuration and the pipeline structure of each waterway, so that the manufacturing cost of products is effectively reduced; and can also provide more stable water flow pressure through the power adjustment to actuating mechanism 12 to do not provide the characteristic of different flow and go out water to different user's user demands, so as to can realize better blowdown and wash, human cleaning performance, and effectively promote water pump device 10 energy-conservation, water conservation, silence effect.

In an embodiment, the driving mechanism 12 specifically further includes a main shaft 121, a rotor 122, and a stator assembly 123, wherein the rotor 122 is sleeved on an outer sidewall of a middle portion of the main shaft 121, and the stator assembly 123 is disposed around the rotor 122 in a containing cavity inside the housing 11, and divides the containing cavity into a first cavity 101 and a second cavity 102 that are not communicated.

The impeller 13 is specifically sleeved on an outer sidewall of one end of the main shaft 121, the gear mechanism 14 is sleeved on an outer sidewall of the other end of the main shaft 121, so that the main shaft 121 is driven to rotate by the rotor 122, and the main shaft 121 further drives the impeller 13 and/or the gear mechanism 14 to rotate, so that the liquid flowing into the first cavity 101 from the water storage mechanism is discharged from the first water outlet 1102, or the liquid flowing into the second cavity 102 from the water storage mechanism is discharged from the second water outlet 1104.

It is understood that the first operating state of the driving mechanism 12 may specifically be one of driving the rotor 122 to rotate in a clockwise direction and a counterclockwise direction, and the second operating state of the driving mechanism 12 may specifically be the other of driving the rotor 122 to rotate in a clockwise direction and a counterclockwise direction, that is, the first operating state and the second operating state may specifically be two states of driving the rotor 122 to rotate in a forward direction and a reverse direction.

For example, when the rotor 122 drives the impeller 13 to rotate clockwise through the main shaft 121, the impeller 13 drives the liquid flowing into the first cavity 101 inside the housing 11 to be discharged from the first water outlet 1102, and at this time, the gear mechanism 14 rotates clockwise synchronously, but cannot discharge the liquid in the second cavity 102 from the second water outlet 1104; when the rotor 122 drives the gear mechanism 14 to rotate counterclockwise through the main shaft 121, the gear mechanism 14 drives the liquid in the second cavity 102 to be discharged from the second water outlet 1104, and the impeller 13 rotates counterclockwise synchronously, but cannot discharge the liquid in the first cavity 101 from the first water outlet 1102.

It should be noted that the above-mentioned forward and reverse rotation is not limited to the uniqueness, that is, specifically, the structure may be adopted, and the impeller 13 is driven to drain when the rotor 122 rotates clockwise, and the gear mechanism 14 is driven to drain when the rotor 122 rotates counterclockwise, and vice versa.

Further, in an embodiment, the driving mechanism 12 specifically further includes two damping assemblies 124, and the two damping assemblies 124 are respectively located at two opposite sides of the rotor 122 and are respectively sleeved on the outer side wall of the main shaft 121, so as to effectively reduce the vibration and noise caused by the vibration when the impeller 13 and the gear mechanism 14 are driven to rotate.

In one embodiment, the driving mechanism 12 specifically further includes a rotor chamber wall 125, where the rotor chamber wall 125 is specifically disposed between the rotor 122 and the stator assembly 123 to isolate the rotor 122 from the stator assembly 123, so as to avoid the liquid in the housing chamber inside the housing 11 from splashing onto the stator assembly 123 from the location where the rotor 122 is disposed, and causing the stator assembly 123 to malfunction.

Optionally, the rotor cavity wall 125 may be a thin-walled metal tube, which is advantageous for minimizing an air gap between the stator and rotor 122, reducing reluctance loss, and optimizing a power factor.

In one embodiment, the driving mechanism 12 further includes a stator housing 126, where the stator housing 126 is connected to the stator assembly 123 and is connected to an inner sidewall of the housing 11, so as to cooperate with a portion of the housing 11 to limit and separate the first cavity 101.

Further, in an embodiment, the water pump device 10 further includes a sealing member 15, wherein the sealing member 15 is sleeved on an outer sidewall of the main shaft 121 near the gear mechanism 14 and abuts against an inner sidewall of the rotor cavity wall 125, so as to cooperate with the rotor cavity wall 125 and a portion of the housing 11 to limit and separate the second cavity 102, and is specifically used for preventing the fluid in the first cavity 101 and the second cavity 102 from flowing in series; the sealing element 15 can also ensure normal rotation and power transmission of the main shaft 121, and prevent pressure relief caused by a gap between the sealing element 15 and the main shaft 121, so as to ensure the stability of output pressure of the gear mechanism 14.

In one embodiment, the gear mechanism 14 specifically further includes a baffle 141 and a gear assembly 142, and the baffle 141 and the gear assembly 142 are sequentially sleeved on the outer sidewall of the other end of the main shaft 121 in a direction away from the impeller 13.

Optionally, the baffle 141 may be made of a metal or non-metal material with good self-lubricating effect, so as to improve the clearance and friction between the baffle and the end surface of the gear assembly 142, and according to the requirements of specific performance, a baffle 141 may be disposed on two opposite sides of the gear assembly 142, so as to avoid abrasion of the gear assembly 142 when driven to rotate, or abrasion of other components, which is not limited in the present utility model.

In one embodiment, the gear mechanism 14 further includes a cover plate 143, and the cover plate 143 is sleeved on the outer sidewall of the other end of the main shaft 121 from the side of the gear assembly 142 facing away from the baffle 141.

Optionally, a pressure relief groove is further provided on the baffle 141 and/or the cover plate 143 to ensure that the gear assembly 142 can operate stably and reduce noise generated when the gear assembly 142 rotates as much as possible.

It can be appreciated that the rotor 122, the impeller 13, the damper assembly 124, the sealing member 15, the baffle 141, the gear assembly 142, etc. are all sleeved on the outer sidewall of the main shaft 121, so that the rotor 122 can rotate by the main shaft 121, and the two ends of the main shaft 121 are specifically assembled on the stator housing 126 and the casing 11 through the damper assembly 124.

The impeller 13 may be understood as a centrifugal pump, and the gear assembly 142 may be understood as a gear pump, to enable a relatively stable flow output. And the gear assembly 142 may include a main gear 1421 and a driven gear 1422 engaged with each other, and further include a stub shaft 1423 connected to the barrier 141; the main gear 1421 is specifically sleeved on the outer side wall of the main shaft 121, and the driven gear 1422 is sleeved on the outer side wall of the short shaft 1423, so that the internal volume of the second cavity 102 can be adjusted by utilizing the process of the meshing movement of the main gear 1421 and the driven gear 1422, so that the liquid flowing into the second cavity 102 from the water storage mechanism can be discharged from the second water outlet 1104.

The gear pump is specifically a rotary pump that delivers or pressurizes liquid by virtue of the change and movement of working volume created between the pump cylinder and the meshing gears. When the gears rotate, the volume of the space at the disengaging side of the gears is changed from small to large, vacuum is formed, liquid is sucked in, the volume of the space at the engaging side of the gears is changed from large to small, and the liquid is extruded into the pipeline. The suction chamber is separated from the discharge chamber by the meshing line of the two gears. The pressure at the discharge of the gear pump is entirely dependent on the amount of resistance at the pump outlet.

In one embodiment, the water pump device 10 further includes a control circuit board 16, and a mounting groove is further formed on a side wall of the housing 11, and the control circuit board 16 is embedded in the mounting groove and is electrically connected to the driving mechanism 12.

It will be appreciated that there is a connection between the control circuit board 16 and the driving mechanism 12 for a control signal and a power supply, and the control circuit board 16 can control the driving mechanism 12 accordingly according to the functional instruction input by the user, so as to achieve cleaning or pollution discharge and flushing of the human body, and provide a voltage or current sufficient for the driving mechanism 12 to work through the power module integrated therein.

And according to the requirements of the overall control logic of the water pump apparatus 10, the control circuit board 16 provides command information to the driving mechanism 12, which may include, but is not limited to, forward and reverse rotation signals and speed regulation signals. The combination of the flow changes required by the cleaning or pollution discharge flushing of the human body and solidified relatively can also be pre-arranged on the control circuit board 16 through a programmed module, so that the control circuit board 16 gives out signals to activate the required programmed module according to actual requirements, and the fluctuation of the rotating speed of the driving mechanism 12 is regulated and controlled.

In another embodiment, the control circuit board 16 may be further used for connecting an external main control circuit board, and the main control circuit board may receive a key command from a user and send the key command to the control circuit board 16, so that the control circuit board 16 can adjust and control the rotational speed fluctuation of the driving mechanism 12.

It can be understood that when the water pump device 10 is specifically applied to the intelligent toilet, the first water outlet 1102 of the water pump device 10 can be specifically a water outlet driven by the impeller 13, so as to have a large flow function, and can combine with a water diversion valve and upper and lower water spraying ports on a rear-end pipeline to realize a sewage flushing and cleaning function; the second water outlet 1104 is a water outlet driven by the gear mechanism 14 and has a protruding water spraying pressure, so that the functions of cleaning the human body can be realized by combining the parts such as a heater, a distribution valve, a human body cleaner and the like on the rear end pipeline.

The driving mechanism 12 can be specifically understood as a dc motor, so that a set of dc motors can be used to drive two sets of waterway components mounted on the main shaft 121, and different waterway components can be driven to work by using the forward and reverse rotation characteristics of the rotor 122, and the dc motors can also realize speed regulation control under the instruction of the control circuit board 16.

It is worth to say that, according to the requirements of pollution discharge flushing on flow and lift, the corresponding working rotation speed of the impeller 13 can be more than 2000 rpm, so that the stable adjustment of the output flow in 30-120L/min can be realized through the function of adjusting the rotation speed of the direct current motor; according to the requirements of the human body cleaning on the flow and the lift, the working rotation speed corresponding to the gear mechanism 14 can be specifically 100-3000 rpm, and the output flow can be regulated within 200-1200 mL/min by the rotation speed adjustable function of the direct current motor, and the maximum lift is 30m.

The driving mechanism 12 may be a brushless dc motor, but is not limited to a motor of one principle, and may be another motor or a power source. The spindle 121 in the driving mechanism 12 may be a linear spindle, which is used as a transmission component for outputting work by a motor, but is not limited to a linear spindle, and the axial direction of rotation may be changed by a structure similar to a gear set, a coupling, a universal joint, etc., so that each driven component does not necessarily work on an axis.
