Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, and in particular to a cleaning device. Background Technology

[0002] Suction cleaning devices are widely used for deep wet cleaning of fabric surfaces such as carpets and upholstery. A typical suction cleaning device includes a fluid delivery system and a fluid recovery system. The fluid delivery system consists of a supply tank, a supply pump, supply tubing, and a fluid distributor in the tool assembly to deliver the cleaning liquid to the surface to be cleaned. The fluid recovery system uses the suction nozzle of the tool assembly, a recovery tank, and a suction source to draw the dirty liquid back. For ease of operation, current suction cleaning devices centrally arrange the supply tank, recovery tank, supply pump, and suction source within the main unit. The cleaning liquid is then delivered to the handheld tool assembly via a hose, and the spray bar or nozzle at the front of the tool assembly evenly distributes it onto the surface to be cleaned.

[0003] However, existing fluid delivery systems generally use a single-speed pump and on / off valve configuration, meaning the supply pump operates at a constant speed with rated power, and users can only achieve two states: fully open or fully closed via a trigger or solenoid valve. The cleaning fluid flow rate remains basically constant and cannot be adjusted according to fabric thickness, degree of soiling, or user's personal habits. Summary of the Invention

[0004] To address the problem that the constant flow rate of cleaning fluid in existing technologies cannot meet user needs, this invention provides a cleaning device that adds the function of adjustable cleaning fluid flow rate.

[0005] To achieve the above-mentioned objectives, one embodiment of this utility model provides a cleaning device, comprising:

[0006] Main body of the device;

[0007] A recycling tank, which is installed on the main body of the device;

[0008] A supply tank, which is installed on the main body of the device;

[0009] A supply pump is disposed within the main body of the device and is in fluid communication with the supply tank;

[0010] A tool assembly connected to the device body and in fluid communication with the supply pump, the tool assembly having a fluid outlet for spraying fluid driven by the supply pump onto the surface to be cleaned;

[0011] A valve device is disposed in the main body of the device and located in the fluid communication path between the tool assembly and the supply pump, and a valve flow channel is formed within the valve device;

[0012] The valve device includes:

[0013] Valve body, the valve body having an inlet and an outlet;

[0014] A valve core, disposed within the valve body, is driveable to rotate to regulate the flow rate of the valve passage;

[0015] An operating element is operatively coupled to the valve core to adjust the rotation angle of the valve core, and at least a portion of the operating element is exposed on the outer surface of the housing of the device body for user operation.

[0016] As a further improvement of this utility model, the valve core has a connecting part, which is located on the outside of the valve body and is fixedly connected to the operating element.

[0017] As a further improvement of this utility model, the valve body includes:

[0018] A first valve body portion, wherein the inlet and the outlet are formed in the first valve body portion;

[0019] The second valve body is fixedly connected to the first valve body and together forms a valve core chamber that accommodates the valve core.

[0020] As a further improvement of this utility model, the valve core includes:

[0021] The first valve core port corresponds to the inlet;

[0022] A second valve core port, which corresponds to the outlet, is formed between the first valve core port and the second valve core port;

[0023] The valve core has multiple rotational positions, and the ratio of the flow rate of the first valve core port and the second valve core port per unit time is different in the multiple rotational positions.

[0024] As a further improvement of this utility model, the valve device further includes:

[0025] A sealing gasket is located between the first valve body and the valve core. One side of the sealing gasket is fixedly connected to the first valve body, and the other side abuts against the valve core. The sealing gasket also has a first flow channel opening that connects the inlet and the first valve core opening, and a second flow channel opening that connects the outlet and the second valve core opening.

[0026] As a further improvement of this utility model, within the rotation range of the valve core, the first valve core orifice covers the first flow channel orifice.

[0027] There are multiple second valve core ports, and the multiple second valve core ports are arranged along the rotation direction of the valve core, wherein the opening size of each second valve core port is different.

[0028] As a further improvement of this utility model, within the rotation range of the valve core, the first valve core orifice covers the first flow channel orifice.

[0029] As the valve core rotates clockwise or counterclockwise, the opening of the flow port formed by the second valve core orifice and the second flow channel orifice gradually decreases.

[0030] As a further improvement of this utility model, the valve core has a connecting portion; the valve device further includes:

[0031] The actuator is fixedly connected to the connecting part;

[0032] A position detection unit, which is communicatively connected to the actuator, is used to detect the position information of the operating element. The position detection unit includes one of a potentiometer, a Hall sensor, and a micro switch.

[0033] As a further improvement of this utility model, the operating component is a knob, and the portion of the knob exposed on the surface of the outer casing is located between the recycling tank and the supply tank.

[0034] As a further improvement of this utility model, the cleaning device further includes:

[0035] A heater, which is disposed within the main body of the device and located in the fluid communication path between the tool assembly and the supply pump;

[0036] A position detection unit is provided to detect the position information of the operating element. The position detection unit is communicatively connected to the heater to activate the heater when the position information indicates that the valve core is in a partially rotated position.

[0037] Compared with commonly used technologies, this utility model has the following advantages: The valve device is located in the fluid path and includes a valve body, a valve core, and exposed operating parts. The valve core can be driven to rotate to adjust the flow rate of the valve channel. Thus, users are no longer limited to a fixed water output mode and can freely control the output of cleaning solution according to their needs and actual conditions. For stubborn stains, a large flow rate can be used for high-intensity rinsing; while for delicate or fragile surfaces, a small flow rate can be used for gentle moist cleaning, avoiding damage or waste of liquid caused by excessive spraying.

However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0053] It should be understood that terms such as “above,” “over,” “below,” and “under” used herein to indicate spatial relative position are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings.

[0054] This application relates to an improvement on cleaning device 1, specifically to a cleaning device that delivers cleaning fluid to the surface to be cleaned and simultaneously has a suction function to recover the cleaned liquid and dirt. The disclosure of this application further relates to a portable cleaning device that can be operated by hand and is suitable for spot cleaning of small areas such as carpets and cushions.

[0055] See Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of the cleaning device 1 according to an embodiment of the present invention. Figure 2 and Figure 3 yes Figure 1 A schematic diagram of the internal structure of the cleaning device 1, which includes:

[0056] Device body 11;

[0057] A recycling tank 12 is installed on the main body 11 of the device.

[0058] Supply tank 13, which is installed on the main body 11 of the device;

[0059] Supply pump 14, which is disposed inside the main body 11 of the device and is in fluid communication with the supply tank 13;

[0060] Tool assembly 15, which is connected to the device body 11 and in fluid communication with the supply pump 14, has a fluid outlet 151 to spray fluid driven by the supply pump 14 onto the surface to be cleaned;

[0061] A valve device 16 is disposed on the device body 11 and located in the fluid communication path between the tool assembly 15 and the supply pump 14, and a valve flow channel is formed within the valve device 16.

[0062] The main body 11 of the device mainly refers to the frame structure and shell of the cleaning device 1, which is used to support and install other components. It is usually designed with various slots, brackets, screw posts and pipe interfaces to fix other components. The main body 11 is usually designed with a handle to facilitate user grip and operation.

[0063] The recovery tank 12 is a container used to temporarily store the liquid and dirt sucked up. The recovery tank 12 can be designed as a detachable structure, so that when the recovery tank 12 is full, it can be disassembled and the whole thing can be picked up and emptied. Understandably, the cleaning device 1 usually also includes a suction source, i.e., a suction motor, used to suck up the liquid and dirt from the surface to be cleaned, and then the liquid and dirt are sent into the recovery tank 12.

[0064] Supply tank 13 is a storage tank for holding clean water and / or cleaning solution. It can also be configured as a detachable structure for easy removal and replenishment of clean water and / or cleaning solution.

[0065] The supply pump 14 is in fluid communication with the supply tank 13 and is used to draw liquid from the supply tank 13 and pressurize it to the outlet end of the tool assembly 15.

[0066] The tool assembly 15 is a component assembly that directly cleans and contacts the surface to be cleaned. It can be, for example, a floor brush with a nozzle, a hand brush, or a squeegee, and is connected to the main body 11 via a flexible hose or rigid linkage. The fluid outlet 151 is a small nozzle or a series of small holes embedded within the tool assembly 15, serving as the outlet for fluid to flow out of the tool assembly 15. Typically, clean water or cleaning fluid is accelerated here and formed into a jet that is sprayed onto the surface to be cleaned.

[0067] Valve device 16 is installed inside device body 11 on the pipeline between supply pump 14 and tool assembly 15.

[0068] In this embodiment, the valve device 16 includes:

[0069] Valve body 161, the valve body 161 having an inlet 1611 and an outlet 1612;

[0070] Valve core 162 is disposed inside the valve body 161 and can be driven to rotate to adjust the flow rate of the valve passage;

[0071] An operating element 163 is operatively coupled to the valve core 162 to adjust the rotation angle of the valve core 162. At least a portion of the operating element 163 is exposed on the outer surface of the housing of the device body 11 for user operation.

[0072] The valve body 161 has an internal chamber, namely the valve core chamber 1615, for accommodating the valve core 162. The valve body 161 has an inlet 1611 and an outlet 1612 that communicate with the valve core chamber 1615. The inlet 1611 and outlet 1612 can be designed as threaded interfaces or quick-connect fittings to facilitate connection to the pipeline supplying the pump 14 and the pipeline leading to the tool assembly 15.

[0073] The valve core 162 is located inside the valve body 161 and within the valve flow channel. The rotation of the valve core 162 changes the effective cross-sectional area of ​​the fluid flow in the valve flow channel. It can be understood that a larger effective cross-sectional area results in a larger flow rate, and a smaller effective cross-sectional area results in a smaller flow rate.

[0074] The operating element 163 is the direct component for the user to operate the valve core 162 to rotate. It can be implemented as a knob or a handle, which is not limited here. At least a portion of the operating element 163 (i.e., the rim of the knob or the end of the handle) passes through the housing of the device body 11 and is exposed within the reach of the user.

[0075] The operative coupling between the operating element 163 and the valve core 162 means that the user can adjust the rotation angle of the valve core 162 by operating the operating element 163. Common operative couplings typically include mechanical coupling and electrical coupling. Mechanical coupling refers to the direct connection and transmission of power or motion between two components through physical mechanical parts, such as gears, connecting rods, and threads, to achieve linkage between the two components. Electrical coupling, on the other hand, uses circuits, electrical signals, or electromagnetic components, such as motors, sensors, and controllers, to indirectly control the action of another component.

[0076] See Figure 4-5 , Figure 4 This is an exploded view of valve device 16 according to an embodiment of this utility model. Figure 5 yes Figure 4 A cross-sectional schematic diagram of valve device 16.

[0077] In this embodiment, the valve core 162 has a connecting portion 1621, which is located outside the valve body 161 and is fixedly connected to the operating member 163.

[0078] The connecting part 1621 is a journal extending from the valve core 162 to the outside of the valve body 161. It can be in the form of a flat square, spline, threaded column, etc., and it is connected to the operating element 163. The connecting part 1621 is completely exposed to the outside of the valve body 161 and isolated from the humid space inside the valve body 161. Therefore, for sealing purposes, a sealing ring is also provided between the valve core 162 and the valve body 161, which will not be described in detail here.

[0079] The valve core 162 is controlled entirely outside the valve body 161 and rigidly connected to the operating element 163. Direct, precise, and hysteresis-free flow regulation can be achieved through the operating element 163.

[0080] See also Figure 4-5 The valve body 161 includes:

[0081] A first valve body portion 1613, wherein the inlet 1611 and the outlet 1612 are formed in the first valve body portion 1613;

[0082] The second valve body 1614 is fixedly connected to the first valve body 1613 and together forms the valve core chamber 1615 that accommodates the valve core 162.

[0083] In this embodiment, the valve body 161 is formed by combining a first valve body portion 1613 and a second valve body portion 1614. The inlet 1611 and outlet 1612 are formed on the first valve body portion 1613, with their relative positions fixed and requiring no further adjustment during subsequent assembly. The pipeline routing is also determined. Because the inlet 1611 and outlet 1612 are concentrated on the first valve body portion 1613, the other half (the second valve body portion 1614) can be made into a simple cover, eliminating the need for further processing of the fluid interface. Both the first valve body portion 1613 and the second valve body portion 1614 are open cavities, making processing simpler compared to a one-piece molded valve body 161, and assembling the valve core 162 is also more convenient.

[0084] In this embodiment, the valve core 162 includes:

[0085] The first valve core port 1622 corresponds to the inlet 1611;

[0086] The second valve core port 1623 corresponds to the outlet 1612, and a valve core flow channel 1624 is formed between the first valve core port 1622 and the second valve core port 1623.

[0087] The valve core 162 has multiple rotational positions, and the ratio of the flow rate of the first valve core port 1622 and the second valve core port 1623 per unit time is different in the multiple rotational positions.

[0088] The first valve core port 1622 is an opening on the surface of the valve core 162, spatially corresponding to the inlet 1611 of the valve body 161. In other words, the first valve core port 1622 is the necessary inlet for the flow from the inlet 1611 of the valve body 161 to the interior of the valve core 162. The second valve core port 1623 is another opening on the surface of the valve core 162, spatially corresponding to the outlet 1612 of the valve body 161. In other words, the second valve core port 1623 is the necessary outlet 1612 for the flow from the interior of the valve core 162 to the outlet 1612 of the valve body 161. The flow path from the first valve core port 1622 to the second valve core port 1623 is the valve core flow path 1624.

[0089] The valve core 162 can be driven to rotate, thus having multiple rotational positions within its rotational range. These multiple rotational positions can be manually defined to correspond to multiple speed settings, each with a different flow rate.

[0090] As the valve core 162 rotates, the actual flow rate of the valve core flow channel 1624 changes, thus displaying flow rate regulation.

[0091] See Figure 6-7 , Figure 6 This is a top view of the first valve body 1613 according to an embodiment of the present invention. Figure 7 This is a top view of the first valve body 1613 (with sealing gasket 164) according to an embodiment of the present invention. In this embodiment, the valve device 16 further includes:

[0092] A sealing gasket 164 is located between the first valve body portion 1613 and the valve core 162. One side of the sealing gasket 164 is fixedly connected to the first valve body portion 1613, and the other side abuts against the valve core 162. The sealing gasket 164 also has a first flow channel port 1641 connecting the inlet 1611 and the first valve core port 1622, and a second flow channel port 1642 connecting the outlet 1612 and the second valve core port 1623.

[0093] The sealing gasket 164 is a deformable gasket placed between the first valve body 1613 and the valve core 162 to prevent fluid leakage and guide the fluid path through the first flow port 1641 and the second flow port 1642. In the installed state, the sealing gasket 164 does not rotate or slide relative to the first valve body 1613, i.e., its relative position is fixed, and the movable side of the sealing gasket 164 is pressed tightly against the surface of the valve core 162 by elastic pressure.

[0094] The first flow channel 1641 and the second flow channel 1642 are two through holes on the sealing gasket 164. This means that the relative positions of the first flow channel 1641 and the second flow channel 1642 with the inlet 1611 and outlet 1612 of the valve body 161 are fixed and will not be misaligned due to the rotation of the valve core 162, ensuring a constant flow area for the first flow channel 1641 and the second flow channel 1642. The actual flow rate change occurs between the first flow channel 1641, the second flow channel 1642, and the corresponding first valve core port 1622 and second valve core port 1623.

[0095] See Figure 8-12 , Figure 8 This is a schematic diagram of the valve core 162 according to an embodiment of the present invention. Figure 9-12 yes Figure 8 A schematic diagram of the valve core 162 in multiple rotational positions.

[0096] In this embodiment, within the rotation range of the valve core 162, the first valve core port 1622 covers the first flow channel port 1641.

[0097] There are multiple second valve core ports 1623, and the multiple second valve core ports 1623 are arranged along the rotation direction of the valve core 162, wherein the opening size of each second valve core port 1623 is different.

[0098] The fact that the first valve core port 1622 covers the first flow channel port 1641 means that the first flow channel port 1641 can always remain fully open, regardless of the rotation position of the valve core 162.

[0099] This embodiment uses four rotational positions as examples. Figure 9-12 The diagram shows the relative positions of the valve core 162 and the valve body 161 at the four rotational positions. From these four rotational positions, the valve core 162 maintains a cover between its first valve core port 1622 and the first flow channel port 1641 of the sealing gasket 164, meaning that the flow rate of the first flow channel port 1641 remains constant.

[0100] There are four second valve core ports 1623, each of which can correspond to a different flow area. The second valve core ports 1623 are distributed angularly around the valve core 162. When the valve core 162 rotates, the second flow channel port 1642 of the sealing gasket 164 aligns with each of the second valve cores 162 in sequence.

[0101] In these four rotational positions, the second flow channel port 1642 is always connected to one of the second valve core ports 1623, thereby regulating the flow rate of the valve core flow channel 1624. Since the inlet end area 1611 of the valve core flow channel 1624 is constant and the outlet end area changes step by step, a clear control characteristic of "constant inlet and proportional outlet adjustment" can be obtained.

[0102] See Figure 13 In some embodiments, the number of second valve core ports 1623 may also be one, but the width of the second valve core port 1623 may vary, thereby achieving the adjustment of different flow rates.

[0103] Specifically, within the rotation range of the valve core 162, the first valve core port 1622 covers the first flow channel port 1641; along the clockwise or counterclockwise rotation direction of the valve core 162, the opening of the flow port formed by the second valve core port 1623 and the second flow channel port 1642 gradually decreases.

[0104] In other words, as the valve core 162 rotates, the effective overlapping area at the outlet end of the valve core flow channel 1624 monotonically decreases. As the valve core 162 rotates, the second valve core port 1623 gradually blocks the corresponding second flow channel port 1642, gradually closing it off. In a specific implementation, the second valve core port 1623 can, for example, be in the form of... Figure 12 The diagram shows a long, narrow through-hole, the width of which gradually decreases along the direction of rotation.

[0105] In some embodiments of this application, the valve core 162 may also be driven to rotate by electrical coupling.

[0106] Specifically, the valve core 162 has a connecting portion 1621; the valve device 16 further includes:

[0107] The actuator is fixedly connected to the connecting part 1621;

[0108] A position detection unit is communicatively connected to the actuator and is used to detect the position information of the operating element 163. The position detection unit includes one of a potentiometer, a Hall sensor, and a micro switch.

[0109] The output end of the actuator is connected to the valve core 162 connection part 1621, which can be, for example, a rigid connection or a gear transmission connection. The position detection unit acquires the position information of the operating element 163, such as the rotation position of the knob or the actuation position of the lever, and transmits it to the controller, which then forwards it to the actuator, or transmits it directly to the actuator. Finally, the actuator drives the valve core 162 to rotate to the position corresponding to the operating element 163.

[0110] Potentiometers, Hall sensors, and microswitches represent three detection methods: contact (potentiometer), non-contact magnetic sensing (Hall sensor), and discrete point position (microswitch). The position detection unit can be any of these three types, and there is no limitation here.

[0111] In this embodiment, the operating element 163 is a knob, and the portion of the knob exposed on the surface of the outer casing is located between the recycling tank 12 and the supply tank 13.

[0112] The area between the recycling tank 12 and the supply tank 13 typically has a support structure; that is, the main body 11 of the device usually has a supporting structure at this location. Placing the knob here does not increase the overall size of the machine and is more intuitive, making it easier for the user to notice the knob's position. Using a knob as the operating element 163 provides a round or near-round part that the user can turn by hand, making the rotation action intuitive and easier for the user to operate.

[0113] See also Figure 2 - 3. In this embodiment, the cleaning device 1 also includes a heater 17 for heating the fluid to enhance the cleaning ability. Furthermore, the operating component 163 of this application has a linkage function with the heater 17 to automatically trigger the heater 17 to work.

[0114] Specifically, the cleaning device 1 further includes:

[0115] Heater 17, which is disposed within the device body 11 and located in the fluid communication path between the tool assembly 15 and the supply pump 14;

[0116] A position detection unit is provided to detect the position information of the operating element 163. The position detection unit is communicatively connected to the heater 17 to activate the heater 17 when the position information indicates that the valve core 162 is in a partially rotated position.

[0117] Heater 17 is a functional component that provides heat to the fluid and is connected in series in the flow path from supply pump 14 to tool assembly 15. The position detection unit, as described above, is used to acquire position information of operating element 163, which essentially also indicates the position of valve core 162.

[0118] As an example, when the valve core 162 is in a partially closed state, i.e. when the valve flow path is open, the heater is activated; when the valve core 162 is in a fully closed state, the heater is deactivated to prevent dry burning.

[0119] As another example, when the valve core 162 rotates to make the valve flow channel have a small flow rate, that is, when the part of the rotation position is in the angle range of small opening / low flow, the heater is started. At this time, the water temperature rises faster and steam can be generated directly.

[0120] In summary, by placing the valve device 16 in the fluid path, the valve device 16 includes a valve body 161, a valve core 162, and an exposed operating element 163. The valve core 162 can be driven to rotate to adjust the flow rate of the valve channel. Thus, users are no longer limited to a fixed water output mode, but can freely control the output of cleaning fluid according to their needs and actual conditions. For stubborn stains, a high flow rate can be used for high-intensity rinsing; while for delicate or fragile surfaces, a low flow rate can be used for gentle moist cleaning, avoiding excessive spraying that could cause damage or waste of liquid.

[0121] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0122] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementation methods or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
