Please refer to FIG. 1. FIG. 1 shows a general schematic diagram of a cleaning apparatus 500 protected by the present invention. The cleaning apparatus 500 includes a motor assembly 100, an air pump 200, and a water pump 300. The motor assembly 100 simultaneously controls the air pump 200 and the water pump 300. The air pump 200 further includes a gas cylinder 210 that stores compressed gas. The washing apparatus 500 further includes a water tank 510 provided with a water inlet 512 and a water outlet 514, and the water outlet 514 is in communication with the water pump 300. The water pump 300 is in communication with the external water spray joint 520, and the water in the water tank 510 is finally discharged from the water spray device 520 through the water pump 300 for cleaning. The gas tank 210 is in communication with an external air jet joint 530. Under the action of the air pump 200, the gas is finally ejected from the air jet joint 530 through the gas tank 210 for inflation. Of course, the cleaning apparatus 500 further includes an energizing device (not shown) that drives the motor assembly 100 to ultimately effect operation of the air pump 200 or the water pump 300 to effect air or water spray. The specific construction and operation of the motor assembly 100 will be described in detail below.

As shown in FIG. 1 and in conjunction with FIG. 2, a motor assembly 100 is used for simultaneously controlling a gas pump 200 and a water pump 300. The motor assembly 100 includes a first gear 110, a second gear 140, and a third gear 150. The third gear 150 is respectively The first gear 110 and the second gear 140 are meshed with each other. The first gear 110 is coupled to the air pump shaft 170 of the air pump 200 via a first unidirectional element 120. The second gear 140 is coupled to the water pump shaft 160 of the water pump 300 via a second unidirectional element 130. The motor 180 drives the third gear 150 to operate, and the third gear 150 drives the unidirectional element to control the air pump 200 and the water pump 300 through the first gear 110 and the second gear 140. In this embodiment, the air pump 200 and the water pump 300 can share the same motor 180, which reduces the cost, reduces the occupied space, and is convenient to carry.

In this embodiment, the unidirectional element includes a first one-way needle bearing 120 and a second one-way needle bearing 130; the first one-way needle bearing 120 and the second one-way needle bearing 130 respectively drive the air pump shaft 170 The water pump shaft 160 is operated. The rolling direction in which the first one-way needle bearing 120 transmits the working torque is opposite to the rolling direction in which the second one-way needle bearing 130 transmits the working torque. When the third gear 150 is in operation, the first needle bearing 120 and the second needle bearing 130 are driven to transmit the working torque.

Motor 180 has a motor shaft 181 that is rotatable about its axis 182 and a third gear 150 that is disposed on motor shaft 181. In the present embodiment, the motor shaft 181 is controllably rotatable in the first direction or the second direction. The first direction and the second direction generally represent two directions that are opposite in direction. The third gear 150 functions as a transmission, and the third gear 150 can simultaneously be coupled to the first gear 110 and the second gear 140 connection.

As shown in FIG. 1 and in conjunction with FIG. 2, in this embodiment, when the motor 180 rotates in the first direction, such as forward rotation (reverse rotation), the third gear 150 drives the air pump 200 with the first gear 110, A gear 110 drives the air pump 200 through the first one-way needle bearing 120, while the third gear 150 drives the water pump 300 with the second gear 140, and the water pump 300 transmits torque through the second one-way needle bearing 130 with the second gear 140. However, at this time, since the direction of the transmission torque of the second one-way needle bearing 130 does not coincide with the direction in which the gear rotates, the torque is not transmitted to the water pump 300, and the water pump 300 does not operate. When the motor 180 rotates in the second direction, such as reverse rotation (forward rotation), the water pump 300 is driven by the third gear 150 with the second gear 140, and the second gear 140 drives the water pump 300 through the second one-way needle bearing 130. At the same time, the third gear 150 also drives the air pump 200 with the first gear 110. The air pump 200 transmits the torque to the air pump 200 through the first one-way needle bearing 120 through the first gear 110, and the air pump 200 does not work. Of course, the unidirectional element is not limited to a needle bearing.

In other embodiments, the unidirectional element can also be configured as a clutch 190 that utilizes clutch 190 to control the transmission of the unidirectional element. When the clutch 190 is in the engaged state, the transmission relationship is connected, at which time the power of the motor 180 can be transmitted to the air pump 200 or the water pump 300. When the clutch 190 is in the disengaged state, the transmission relationship is broken, at which time the power of the motor 180 cannot be transmitted to the air pump 200 or the water pump 300.

Referring to one embodiment illustrated in FIG. 3, the clutch 190 includes a first clutch that connects the air pump 200 and a second clutch that connects the water pump 300. The user can selectively engage the first clutch while the second clutch disengages, at which time the motor 180 drives the air pump 200 to operate, while the water pump 300 is in a stopped state; the user can also selectively disengage the first clutch. At the same time, the first clutch is engaged, at which time the motor 180 drives the water pump 300 to operate, and at this time, the air pump 200 is in a state of being stopped. By setting the first and second clutches, a single motor can be selected to start the air pump 200 or the water pump 300, the whole structure is more compact, and the user operation is also quite convenient.

Additionally, it will be appreciated by those skilled in the art that the air pump 200 and the water pump 300 are separately coupled using two different states of the single clutch 190. In one of the embodiments the clutch is disposed on the output shaft that connects the air pump 200 and the water pump 300, and in other embodiments the clutch is disposed on the output shaft of the motor 180. In addition, it is worth noting that the positions of the first gear 110 and the second gear 140 are not limited to being disposed on both sides of the third gear 150, that is, the air pump shaft 170 and the water pump shaft 160 may be disposed at The same side of the third gear 150 may also be disposed on both sides of the third gear 150.

In addition, it is worth noting that the positions of the first gear 110 and the second gear 140 are not limited to being disposed on both sides of the third gear 150, that is, the air pump shaft 170 and the water pump shaft 160 may be disposed on the third gear 150. The same side may also be disposed on both sides of the third gear 150.

In one of the embodiments, the motor assembly 100 further includes at least two speed switches that control the running direction of the third gear 150, respectively. In this embodiment, the switch should include at least an air pump and a water pump, and the user can manually operate the switch to select whether the air pump 200 is operating or the water pump 300 is operating.

As shown in FIG. 2 and in conjunction with FIG. 4, an air pump and water pump integrated machine includes the motor assembly 100, the air pump 200, and the water pump 300 described above. In addition, it is worth noting that the air pump 200 and the water pump 300 can be used in different occasions or in common situations. For example, the user can use only the air pump 200 in the air pump and the water pump integrated machine to inflate tires such as bicycles and automobiles. It can also be used for air washing and water washing when washing.

In one embodiment, a seat machine for placing the motor assembly 100 is further included; the air pump 200 is integrally disposed in the base machine, and an air outlet pipe is taken out from the base machine, and one end of the air outlet pipe is connected to the air pump 200. In this embodiment, the air pump 200 is integrally disposed in the base unit, and the user only needs to hold the air outlet tube to use the high-pressure gas extracted by the air pump 200 to perform air washing, inflation, and the like. Here, the air pump and water pump integrated machine refers to a cleaning device, and the landline refers to a casing of the cleaning device.

In one embodiment, a handheld work device 400 is also included. The hand-held work device 400 is coupled to the air pump 200 and the water pump 300. The air pump 200 is integrally disposed within the hand-held work device 400. In this embodiment, the hand-held work device 400 is used to output the gas, water, and water discharged from the air pump 200, the water pump 300. The air pump 200 and the water pump 300 output a gas and water with a certain pressure through the hand-held working device 400, and the user can hold the work device 400 to clean the article. Since the air pump 200 is small in volume, it can be integrated in the hand-held working device 400, so that the switch for controlling the output of the air pump 200 can be disposed on the hand-held working device 400 as needed, and the user directly controls the air-out condition through the control switch to perform the work of cleaning the object. In addition, the cleaning device can also be provided with a control switch for controlling the direction of rotation of the motor. Handheld work device 400 herein is also referred to as a spray gun. The spray gun is used by the operator and can be separated from the housing of the cleaning device. The spray gun is connected to the housing of the cleaning device by a water pipe at a certain distance. The water pipe is flexible and easy to curl when stretched or stored. In this way, when cleaning in different places, it is only necessary to move the holding gun without moving the housing of the cleaning device. The weight of the spray gun is usually lighter and the weight of the cleaning equipment Usually heavier.

In one of the embodiments, the air pump 200 further includes a gas cylinder 210 that stores compressed gas. In this embodiment, the arrangement of the gas tank 210 can buffer the gas pressure of the gas outputted by the air pump 200, so that the working effect of the air pump 200 is better.

Compared with the conventional technology, the motor assembly 100 of the present invention can control the operating states of the air pump 200 and the water pump 300 through gears and associated one-way needle bearings. In this way, where both air washing and water washing are required, the volume is small and the carrying is more convenient. The utility model relates to an air pump and a water pump integrated machine, which comprises the motor assembly 100, the air pump 200, the water pump 300 and the hand-held working device 400, which are conveniently carried and directly air-washed or washed by the hand-held working device 400.

In still another embodiment, the air pump 200 can also be combined with the water pump 300 to form a pump that is driven by the motor 300. When water is injected into the pump, the pump can be used as a water pump to increase the pressure of the water. When injecting gas into the pump, the pump can be used as an air pump to raise the gas pressure. In this way, the cleaning device can be simplified to only one pump and one motor for driving the pump, thereby further simplifying the overall volume and structure.

Additionally, it is worth noting that the cleaning apparatus of the present invention also has a water tank for storing water. The water to be added to the water pump can be stored in advance in the water tank. It is easy to access when needed, especially in places where water is not readily available, such as roads, mountains, and wilderness. This can expand the range of applications of cleaning equipment. In some occasions where water sources can be easily accessed, such as fields, homes, ponds, in a preferred embodiment, water pipes, even spray guns on connecting pipes, can be placed in an external water source, and the pump can generate suction. The suction force draws water from the external water source into the water tank through the water pipe. When cleaning is required, the pressure generated by the water pump can spray the water stored in the water tank through the water pipe and the spray gun on the connecting water pipe. In this way, the pump has multiple functions of suction and outward spraying, which can further enhance the portable usability of the cleaning device.
