Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaners, and in particular to a vacuum cleaner water pump. Background Technology

[0002] In most households, wet and dry vacuum cleaners are commonly used to clean areas with standing water. However, current wet and dry vacuum cleaners lack automatic drainage systems. This means that the vacuum cleaner drum needs to be emptied manually when full, which is time-consuming, laborious, and inconvenient.

[0003] For example, publication number "CN221844571U" discloses "a three-in-one wet and dry canister vacuum cleaner," comprising: a canister body, a suction port on the surface of the canister body, a detachable steel pipe on the surface of the suction port, an adapter fixedly connected to one end of the detachable steel pipe, a brush head fixedly connected to the other end of the adapter, a filter assembly inside the canister body, a vacuum cleaner cover rotatably connected to one side of the canister body, a vacuum cleaner motor fixedly connected to the bottom of the canister body, multiple casters on the bottom of the vacuum cleaner motor, and the suction port of the vacuum cleaner motor connected to the suction port through the filter assembly; a blower port fixedly connected to the back of the canister body; and a portable battery assembly fixedly connected to the back of the vacuum cleaner motor. However, in practical applications, the vacuum cleaner canister needs to be manually emptied after it is full of water, which is time-consuming, laborious, and inconvenient to use. Summary of the Invention

[0004] In view of the problem mentioned in the background art that the existing technology does not have an automatic drainage device and requires manual emptying, this utility model provides a vacuum cleaner water pump that can automatically drain water from the vacuum cleaner's bucket by connecting to the vacuum cleaner during use, making it convenient for users to operate, improving efficiency, and ensuring the safety of the water pump during use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A vacuum cleaner water pump includes a main body, a connecting pipe for connecting to a vacuum cleaner, a drain pipe, an installation cavity within the main body, a drive component within the installation cavity, a flow channel between the connecting pipe and the drain pipe, an impeller connected to the drive component within the flow channel, and a gravity control unit connected to the main body. The gravity control unit includes a placement slot, a push-button switch at the bottom of the placement slot, and a movable ball placed within the placement slot. With the continuous development of modern cleaning equipment technology, wet and dry vacuum cleaners have become important tools in commercial and household cleaning fields due to their multi-functional characteristics. These devices, by improving the airflow structure and separation system of traditional vacuum cleaners, achieve dual processing capabilities for solid particulate matter and liquid wastewater. A typical structure usually includes a dust collection bin with a centrifugal fan driven by a high-speed motor. When the device is in wet operation mode, through the air intake channel and liquid backflow prevention device, residual liquid on the ground can be sucked into a storage container, meeting the cleaning needs of humid environments such as kitchens and bathrooms.

[0007] However, during use, these types of vacuum cleaners are equipped with water tanks to collect wastewater. After cleaning or when the tank is full, it needs to be emptied manually. This process involves disassembling and reinstalling the water tank. After use, the water tank also needs to be cleaned and dried to prevent bacteria from growing in the wastewater. Therefore, this creates extra steps during use, leading to decreased work efficiency and making the cleaning process more cumbersome. In addition, when the vacuum cleaner is too large, the volume of the water tank will also increase, making it difficult to remove and empty the tank when it is full, causing some degree of difficulty in use.

[0008] Therefore, in response to the problems existing in the use of the aforementioned wet and dry vacuum cleaners, this application connects a water pump to the vacuum cleaner. The water pump includes a main body with a drain pipe and a connecting pipe on the main body. The connecting pipe and the drain pipe are connected. A flow channel is provided inside the main body, which connects the drain pipe and the connecting pipe. The connecting pipe can be connected to the vacuum cleaner. The sucked-in water flows through the flow channel into the drain pipe, thereby realizing the transportation of wastewater. A driving component is provided in the mounting cavity, and an impeller is connected to the driving component. The impeller is located in the flow channel. Driven by the driving component, the impeller rotates in the flow channel, thereby generating negative pressure inside the flow channel. This allows water in the connecting pipe to be sucked into the flow channel, and centrifugation is used to discharge the water from the drain pipe, thus achieving the effect of automatic drainage. In this application, since a driving component is installed within the mounting cavity, and this component is always operational during use, the continued operation of the driving component if the vacuum cleaner is tilted during use could potentially damage the device. Therefore, a gravity control unit is installed within the mounting cavity. This gravity control unit includes a placement slot containing a movable ball. A push-button switch is located at the bottom of the placement slot. During operation, when the vacuum cleaner is in its normal placement position, the movable ball, due to gravity, will be positioned at the bottom of the placement slot, thus creating a pressing effect due to the gravity of the movable ball. The push-button switch at the bottom of the placement slot is triggered, ensuring the drive unit remains operational. When the vacuum cleaner tilts, the placement slot also tilts, preventing the movable ball from remaining at the bottom and thus preventing the push-button switch from being activated. This disconnects the drive unit, preventing it from operating while the vacuum cleaner is tilted. The movable ball in this application is spherical, allowing it to roll flexibly within the placement slot in all states, resulting in more sensitive response from the drive unit during placement state transitions. In this application, the drive unit includes, but is not limited to, a motor.

[0009] Preferably, the placement slot has an opening larger than the size of the movable ball, and a stop bar is provided at the top of the placement slot within the mounting cavity. The placement slot has an opening larger than the movable ball to allow for quick placement, while the stop bar within the mounting cavity blocks the opening, preventing the movable ball from detaching from the opening if the vacuum cleaner tipes over.

[0010] Preferably, the placement groove is a spherical groove. By setting the shape of the placement groove as a spherical groove structure, the placement groove can be better adapted to the shape and structure of the movable ball, thereby ensuring that the movable ball can roll flexibly in the placement groove.

[0011] Preferably, the flow channel includes a conversion chamber for placing the impeller. In the direction of gravity, the connecting pipe is located below the conversion chamber and is connected to the center of the conversion chamber. By positioning the connecting pipe below the conversion chamber, water can be driven to move from the connecting pipe to the drain pipe only when the impeller rotates and generates negative pressure, thus ensuring effective control of the water flow.

[0012] Preferably, the flow channel includes a conversion chamber for housing the impeller. The conversion chamber has a disc structure, and the drain pipe is tangential to and connected to the edge of the conversion chamber. By tangentially connecting the drain pipe to the conversion chamber, centrifugal force is generated during impeller rotation to discharge water from the edge of the conversion chamber, ensuring smooth water flow at the junction of the drain pipe and the conversion chamber.

[0013] Preferably, a switch button is provided on the top of the main body. This top-mounted switch button allows users to more easily control the on / off state of the drive components, improving operational flexibility.

[0014] Preferably, a one-way valve is provided between the drain pipe and the flow channel. The one-way valve prevents water in the drain pipe from flowing back into the flow channel, ensuring that the water flow in the vacuum cleaner is unidirectional.

[0015] Preferably, a filter unit is detachably connected inside the connecting pipe. The filter unit filters wastewater flowing into the flow channel through the connecting pipe, thus preventing impeller blockage in the flow channel. The filter unit is detachably connected to the connecting pipe, facilitating subsequent disassembly and cleaning by the user.

[0016] Preferably, the filtration unit includes a retaining ring with a filter screen connected to it, and the retaining ring engages with the mounting port. The filtration unit includes a retaining ring and a filter screen, wherein the retaining ring and the filter screen are connected, and the retaining ring engages with the mounting port, so that when wastewater flows into the flow channel through the connecting pipe, it first passes through the filter screen, thus ensuring that impurities are effectively removed.

[0017] Preferably, a mounting plate is provided inside the mounting cavity, and a retaining ring is provided on the mounting plate, with the driving component disposed within the retaining ring. By providing a mounting plate inside the mounting cavity, the driving component is effectively fixed and constrained, preventing instability in the connection caused by vibration or other effects during operation. The retaining ring on the mounting plate allows the driving component to be fitted inside the mounting plate, thereby ensuring the operational stability of the driving component.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) During use, it can automatically wash water out of the vacuum cleaner's bucket by connecting to the vacuum cleaner, making it convenient for users to operate and improving efficiency. At the same time, it can ensure the safety of the water pump during use.

[0020] (2) It can quickly disconnect the drive unit when the vacuum cleaner is tilted to prevent the drive unit from working continuously and ensure that the overall structure of the device is not damaged.

[0021] (3) It can prevent the backflow of inhaled sewage;

[0022] (4) It can filter impurities from the wastewater of mobile phones and facilitate subsequent impurity cleaning, thereby improving operational efficiency. Attached Figure Description

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] Example 1:

[0039] like Figure 1 , 2 As shown in Figures 3, 4, and 5, a vacuum cleaner water pump includes a main body 1, a connecting pipe 2 for connecting to a vacuum cleaner, a drain pipe 3, an installation cavity 11 inside the main body 1, a drive component 12 inside the installation cavity 11, a flow channel 4 between the connecting pipe 2 and the drain pipe 3, an impeller 13 connected to the drive component 12 inside the flow channel 4, and a gravity control unit connected to the main body 1. The gravity control unit includes a placement slot 51, a push switch 52 at the bottom of the placement slot 51, and a movable ball 53 placed inside the placement slot 51. With the continuous development of modern cleaning equipment technology, wet and dry vacuum cleaners have become important tools in commercial and household cleaning fields due to their multi-functional characteristics. These devices achieve dual processing capabilities for solid particulate matter and liquid wastewater by improving the air path structure and separation system of traditional vacuum cleaners. A typical structure usually includes a dust collection bin with a centrifugal fan driven by a high-speed motor. When the equipment is in wet operation mode, it can draw residual liquid on the ground into the storage container through the air intake channel and the liquid anti-backflow device, which can meet the cleaning needs of humid environments such as kitchens and bathrooms.

[0040] Because these types of vacuum cleaners are equipped with a water tank for collecting wastewater, it needs to be emptied manually after cleaning or when the tank is full. This process involves disassembling and reinstalling the water tank. After use, the water tank also needs to be cleaned and dried to prevent bacteria from growing in the wastewater. This creates extra steps during use, leading to decreased work efficiency and making the cleaning process more cumbersome. In addition, when the vacuum cleaner is too large, the volume of the water tank will also increase, making it difficult to remove and empty the tank when it is full, causing some degree of difficulty in use.

[0041] Traditional wet / dry vacuum cleaners have the following significant drawbacks in practical applications: During wet cleaning, the limited liquid capacity of the dehumidifier's tank necessitates frequent interruptions of the dust and water suction process to empty the liquid. This is especially problematic when dealing with large areas of standing water or in continuous operation scenarios, requiring users to repeatedly stop work and empty the tank, resulting in an inconsistent cleaning process and significantly reduced work efficiency. Furthermore, existing liquid containers often feature a top-opening design, requiring disassembly or tilting of the tank for emptying, which can easily lead to wastewater splashing and contamination of the operating environment and personnel. In addition, insufficient sealing may cause wastewater to flow back along the tank wall into the interior of the device, posing a risk of damaging critical components or fostering bacterial growth. After emptying the liquid, users also need to manually clean any remaining stains on the inner wall of the tank and maintain the filter components, causing inconvenience. Moreover, with prolonged use, mold can easily grow inside the tank due to liquid residue, and some liquid components may corrode plastic parts and sealing structures, affecting the lifespan of the equipment and hygiene safety. Meanwhile, in industrial applications, there are scenarios that require large-scale industrial cleaning. Traditional equipment struggles to balance liquid storage capacity with mobility: increasing capacity leads to bulky equipment, while small-capacity designs require frequent drainage.

[0042] Therefore, in response to the problems existing in the use of the aforementioned wet and dry vacuum cleaner, this application connects a water pump to the vacuum cleaner. The water pump includes a main body 1, on which a drain pipe 3 with a connecting pipe 2 is provided. The connecting pipe 2 and the drain pipe 3 are connected. A flow channel 4 is provided inside the main body 1, which connects the drain pipe 3 and the connecting pipe 2. The connecting pipe 2 can be connected to the vacuum cleaner. The sucked-in water flows into the drain pipe 3 through the flow channel 4, thereby realizing the transportation of sewage. A drive component 12 is provided inside the mounting cavity 11, and an impeller 13 is connected to the drive component 12. The impeller 13 is located in the flow channel 4. Driven by the drive component 12, the impeller 13 rotates in the flow channel 4, thereby generating negative pressure inside the flow channel 4. This allows water in the connecting pipe 2 to be sucked into the flow channel 4, and the water is discharged from the drain pipe 3 through centrifugal force, thereby achieving the effect of automatic drainage. In this application, since a drive unit 12 is installed inside the mounting cavity 11, the drive unit 12 is always in working condition during use. However, if the vacuum cleaner is tilted during use, the continuous operation of the drive unit 12 may damage the device. Therefore, a gravity control unit is installed inside the mounting cavity 11. The gravity control unit includes a placement slot 51, in which a movable ball 53 is installed. A push switch 52 is installed at the bottom of the placement slot 51. During operation, when the vacuum cleaner is in a normal placement state, the movable ball 53 will be at the bottom of the placement slot 51 due to gravity. Thus, due to the pressing effect of the gravity of the movable ball 53, the vacuum cleaner will... The push switch 52 at the bottom of the placement slot 51 is triggered, ensuring that the drive unit 12 is always in working condition. When the vacuum cleaner is tilted, the placement slot 51 tilts simultaneously, and the movable ball 53 can no longer maintain its position at the bottom of the placement slot 51, thus failing to trigger the push switch 52. This disconnects the drive unit 12, preventing it from continuing to operate when the vacuum cleaner is tilted. In this application, the movable ball 53 is spherical, ensuring it can roll flexibly within the placement slot 51 in all states, making the drive unit 12 more responsive during placement state switching. In this application, the drive unit 12 includes, but is not limited to, a motor.

[0043] like Figure 3 , 4 As shown, the placement slot 51 has an opening 54, the size of which is larger than the size of the movable ball 53. A stop bar 55 is located at the top of the placement slot 51 within the mounting cavity 11. The placement slot 51 has an opening 54, and the size of the opening 54 is set larger than the size of the movable ball 53 to allow for quick placement of the movable ball 53. The stop bar 55 within the mounting cavity 11 blocks the opening 54, preventing the movable ball 53 from detaching from the opening 54 if the vacuum cleaner tipes over.

[0044] like Figure 4 As shown, the placement groove 51 is a spherical groove. By setting the shape of the placement groove 51 as a spherical groove structure, the placement groove 51 can better adapt to the shape and structure of the movable ball 53, thereby ensuring that the movable ball 53 can roll flexibly in the placement groove 51.

[0045] like Figure 3 As shown, a switch button is provided on the top of the main body 1. The switch button on the top makes it easier for users to control the on / off state of the drive unit 12, improving the flexibility of use.

[0046] A one-way valve is installed between the drain pipe 3 and the flow channel 4. The one-way valve prevents water in the drain pipe 3 from flowing back into the flow channel 4, ensuring that the water flow in the vacuum cleaner is unidirectional.

[0047] like Figure 3 , 5 As shown, a mounting plate 14 is provided inside the mounting cavity 11, and a retaining ring 15 is provided on the mounting plate 14. The driving component 12 is disposed within the retaining ring 15. By providing the mounting plate 14 inside the mounting cavity 11, the driving component 12 is effectively fixed and constrained, preventing the driving component 12 from becoming unstable due to vibration or other effects during operation. The retaining ring 15 on the mounting plate 14 allows the driving component 12 to be fitted inside the mounting plate 14, thereby ensuring the working stability of the driving component 12.

[0048] Example 2:

[0049] like Figure 6 As shown, in this embodiment, the flow channel 4 includes a conversion chamber 41 for placing the impeller 13. In the direction of gravity, the connecting pipe 2 is located below the conversion chamber 41, and the connecting pipe 2 is connected to the center of the conversion chamber 41. By placing the connecting pipe 2 below the conversion chamber 41, the water flow can be driven from the connecting pipe 2 to the drain pipe 3 only when the impeller 13 rotates and generates negative pressure, thus ensuring the control effect of the water flow.

[0050] The flow channel 4 includes a conversion chamber 41 for housing the impeller 13. The conversion chamber 41 has a disc structure, and the drain pipe 3 is tangential to and connected to the edge of the conversion chamber 41. By tangentially connecting the drain pipe 3 to the conversion chamber 41, centrifugal force is generated during the rotation of the impeller 13 to discharge water from the edge of the conversion chamber 41, ensuring smooth water flow at the junction between the drain pipe 3 and the conversion chamber 41.

[0051] In addition to the above-mentioned structural features, this embodiment also includes a main body 1, on which a connecting pipe 2 capable of connecting to a vacuum cleaner is provided, a drain pipe 3 is provided on the main body 1, an installation cavity 11 is provided inside the main body 1, a driving component 12 is provided inside the installation cavity 11, a flow channel 4 is provided between the connecting pipe 2 and the drain pipe 3, an impeller 13 connected to the driving component 12 is provided inside the flow channel 4, and a gravity control unit is connected to the main body 1. The gravity control unit includes a placement slot 51, a push switch 52 is provided at the bottom of the placement slot 51, and a movable ball 53 is placed inside the placement slot 51.

[0052] The placement slot 51 has an opening 54, the size of which is larger than the size of the movable ball 53. A stop bar 55 is located at the top of the placement slot 51 within the mounting cavity 11. The placement slot 51 has an opening 54, and the size of the opening 54 is set larger than the size of the movable ball 53 to allow for quick placement of the movable ball 53. The stop bar 55 within the mounting cavity 11 blocks the opening 54, preventing the movable ball 53 from detaching from the opening 54 if the vacuum cleaner tipes over.

[0053] The placement groove 51 is a spherical groove. By setting the shape of the placement groove 51 as a spherical groove structure, the placement groove 51 can better adapt to the shape and structure of the movable ball 53, thereby ensuring that the movable ball 53 can roll flexibly in the placement groove 51.

[0054] A switch button is provided on the top of the main body 1. The switch button on the top makes it easier for users to control the on / off state of the drive unit 12, improving the flexibility of use.

[0055] A one-way valve is installed between the drain pipe 3 and the flow channel 4. The one-way valve prevents water in the drain pipe 3 from flowing back into the flow channel 4, ensuring that the water flow in the vacuum cleaner is unidirectional.

[0056] A mounting plate 14 is provided inside the mounting cavity 11, and a retaining ring 15 is provided on the mounting plate 14. The driving component 12 is disposed within the retaining ring 15. By providing the mounting plate 14 inside the mounting cavity 11, the driving component 12 is effectively fixed and constrained, preventing the driving component 12 from becoming unstable due to vibration or other effects during operation. The retaining ring 15 on the mounting plate 14 allows the driving component 12 to be fitted inside the mounting plate 14, thereby ensuring the working stability of the driving component 12.

[0057] Example 3:

[0058] like Figure 7As shown, in this embodiment, a filter unit 21 is detachably connected inside the connecting pipe 2. The filter unit 21 is provided inside the connecting pipe 2, which can filter the sewage flowing into the flow channel 4 from the connecting pipe 2, thereby preventing the impeller 13 in the flow channel 4 from becoming blocked. The filter unit 21 is detachably connected to the connecting pipe 2, which facilitates subsequent disassembly and cleaning by the user.

[0059] The filter unit 21 includes a retaining ring 22, on which a filter screen 23 is connected. The retaining ring 22 is engaged with the mounting port. The filter unit 21 includes a retaining ring 22 and a filter screen 23, wherein the retaining ring 22 and the filter screen 23 are connected, and the retaining ring 22 is engaged with the mounting port. This allows wastewater to be filtered by the filter screen 23 before flowing into the flow channel 4 through the connecting pipe 2, thus ensuring that impurities are effectively removed.
