Description

Technical Field

[0001] This disclosure relates to the field of cleaning tool technology, and more specifically, to a cleaning device having a pipeline design capable of spraying multiple media. Background Technology

[0002] Cleaning equipment plays a vital role in efficient cleaning. As people increasingly pursue higher quality in cleaning, cleaning equipment is widely used in commercial applications and even incorporated into daily cleaning work. However, existing cleaning equipment has relatively simple functions, only capable of single-mode foam cleaning, steam cleaning, or spray suction cleaning. The fundamental reason for this is the relatively simple pipeline design of cleaning equipment. The pipeline design of existing cleaning equipment can only support single-media spray suction, such as only spraying hot and cold water and recycling it, or only spraying steam, or pumping cleaning agents to form foam for spraying. However, for different cleaning objects, cleaning types, and stain categories, it is necessary to select appropriate or combine various cleaning methods to achieve high-quality cleaning. For example, oil stains require spraying foam or steam, or steam carrying foam, while mud stains only require spraying water. In addition, different cleaning functions need to be used flexibly for different cleaning objects such as curtains, glass, stoves, and cars. Therefore, the pipeline design of existing technology limits the expansion of cleaning functions of cleaning equipment, resulting in low integration and insufficient flexibility.

[0003] In addition, the water suction switch of existing cleaning equipment is located on the machine body, which makes it impossible to flexibly start and stop the water suction function quickly according to different cleaning operations;

[0004] In view of this, this design proposes a cleaning device with a pipeline design that can spray multiple media, enabling the spraying of steam, detergent, foam, hot water and cold water to meet the needs of multi-functional cleaning operations.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

Detailed Implementation

[0026] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0027] In this example embodiment, a cleaning device with a pipeline design capable of spraying multiple media is provided, such as... Figures 1-3 As shown, the device includes a body 300, a controller 360, a spray pipeline system, a water suction branch 400, a tubing bundle, and a cleaning handle 100. The cleaning handle 100 is an integrated spray and suction handle, connected to the body 300 via a tubing bundle 200. The tubing bundle 200 consists of a water suction pipe 210 and a water spray pipe 220, which are stored parallel to each other along the lines through a retractable nylon tubing bag. The body 300 is equipped with a wastewater tank 330, a clean water tank 320, and a detergent tank 810. A control panel 310 is located on the side of the casing. The tubing bundle 200 extends from the front of the body 300, and various quick-connect connectors are provided on the front of the casing. The controller 360, the spray pipeline system, and the water suction branch 400 are internally encapsulated within the body 300. The cleaning handle 100 is connected to the spray pipeline system via the water spray pipe 220 and to the water suction branch 400 via the water suction pipe 210.

[0028] The spray pipeline system supports the spraying of various media, including a spray branch 500, a steam branch 600, a foam branch 800, and a connecting branch 900. The spray branch 500 is connected to the clean water tank 320 and can spray hot and cold water. A water supply pump 510, a heater, and a spray check valve 520 are installed on it in sequence. The water supply pump 510 can be a submersible pump or a land-based cold water pump. According to the mode selection of the control panel 310, in cold water mode, cold water can be sprayed by directly turning on the cleaning handle 100; in hot water mode, the controller 360 starts the heater (not shown in the figure) to heat the cleaning medium to the set temperature, and the spray button 110 of the cleaning handle 100 is turned on to spray hot water.

[0029] The jetting branch 500 can also jet steam, foam, and steam foam. The steam branch 600 is connected in parallel to the jetting branch 500 and is connected in parallel with the water supply pump 510. The steam branch 600 is equipped with a steam pump 610, an evaporator 620, a pressure sensor 630, and a steam solenoid valve 640 in sequence. The steam pump 610, evaporator 620, pressure sensor 630, and steam solenoid valve 640 are all connected to the controller 360. The steam pump 610 is a diaphragm pump. When switching to steam mode, the steam pump 610 starts to pump clean water from the clean water tank 320. The clean water is heated by the evaporator 620 to form steam. The pressure sensor 630 sends a pressure signal to the controller 360. When the steam pressure reaches the preset steam pressure, the controller 360 starts the steam solenoid valve 640 to open the steam branch 600 and opens the jetting button 110 on the cleaning handle 100. The steam is jetted from the cleaning handle 100 at the end of the jetting branch 500 through the jetting check valve 520.

[0030] One end of the foam branch 800 is connected to the detergent tank 810, which is equipped with a detergent pump 820 and a blower 830. The detergent pumped by the detergent pump 820 is injected into the air by the blower 830 to form foam. The other end of the foam branch 800 is connected in parallel to the connecting branch via a T-junction to a foam quick-connect connector 343. The foam quick-connect connector 343 is used to connect a dedicated dry foam brush head, combining chemical and physical cleaning to achieve deep cleaning of rough surfaces. The foam quick-connect connector 343 is equipped with a foam regulating valve 344. Both are located on the front of the machine body 300. The foam regulating valve 344 is electrically connected to the detergent pump 820 and the blower 830 via a positioner 840 to synchronously adjust the detergent pumping volume and the blower volume to control the foam spray volume. In addition, a foam power interface 342 is also provided on the front of the machine body 300 to provide additional power for foam spraying to support multi-terminal simultaneous cleaning operations, such as... Figure 2 As shown, the foam power interface 342 is connected to the controller 360 through a power supply line to supply power to the detergent pump 820 and the blower 830. A power adapter 350 is provided on the power supply line.

[0031] In addition, the foam can also be sprayed for cleaning through the cleaning handle 100. The foam branch 800 is connected to the spray branch 500 at the rear end of the spray check valve 520 through the connecting branch 900. The connecting branch 900 is equipped with a foam check valve 910, which can cut off the passage from the foam branch 800 to the spray branch 500 in one direction.

[0032] Understandably, the cleaning device also has a steam foam cleaning function. Under the premise of supporting the steam foam mode, the controller 360 simultaneously activates the steam branch 600 and the foam branch 800, and the cleaning handle 100 sprays steam foam to achieve dual cleaning of steam and foam for deep cleaning of stubborn oil stains.

[0033] To meet the needs of high-pressure cleaning scenarios, such as high-pressure cleaning of the exterior walls of high-rise buildings, the cleaning equipment is set to a high-pressure water mode. The spray pipeline system also includes a high-pressure spray branch 700. One end of the high-pressure spray branch 700 is connected to the clean water tank, and the other end is connected to the high-pressure quick connector 341. It forms a parallel path with the spray branch 500. A high-pressure pump 710 is installed on the high-pressure spray branch 700, and the high-pressure quick connector 341 is equipped with a high-pressure regulator. The high-pressure pump 710 pumps the cleaning medium, and the high-pressure regulator forms a high spray pressure. Since the pressure resistance of the cleaning handle 100 is insufficient, a high-pressure nozzle is used for spraying. The high-pressure nozzle is quickly connected to the high-pressure quick connector through the high-pressure nozzle pipe.

[0034] In one exemplary embodiment of this disclosure, the end of the water absorption branch 400 is connected to the cleaning handle 100 via a water absorption pipe 210, such as... Figure 1 As shown, the cleaning handle 100 is an integrated spray and suction handle with a curved grip. A suction button 120 and a spray button 110 are arranged side-by-side on the neck of the handle, accessible by the index finger. The suction button 120 is electrically connected to the controller 360; pressing the button activates or deactivates the vacuum pump 410, allowing for convenient stopping of the suction function during steam or foam spraying. The cleaning handle 100 has a built-in spray valve, and the spray button 110 controls the opening and closing of the spray branch 500, allowing for activation and deactivation of the spray function as needed. It supports switching between multiple cleaning modes; the water suction branch 400 is connected to the sewage tank 330, the lower end of the sewage tank 330 is embedded in the body 300 and forms a closed whole. The sewage tank 330 is equipped with a drainage branch, and a drainage pump 440 is installed on the drainage branch. The sewage tank 330 has a built-in water level sensor 430. When the water level in the sewage tank 330 reaches the warning water level, the water level sensor 430 sends a signal to the relay 420, and the relay 420 sends a start signal to the drainage pump 440 to pump water, preventing the vacuum suction pump 410 from overheating.

[0035] In addition, the regulator 840 has a built-in alarm circuit to alert the sewage tank 330 to the state of being full; the water level sensor 430 of the sewage tank 330 is electrically connected to the regulator 840 to alarm the warning water level; thus, the cleaning equipment automatically drains the sewage when it reaches the warning water level, realizing intelligent and automated drainage control and timely warning.

[0036] In one exemplary embodiment of this disclosure, the control panel 310 is electrically connected to the controller 360, which is provided with a cleaning parameter display screen, a water suction master control button, a spray master control button, a spray pressure adjustment knob, a temperature adjustment button, a steam pressure adjustment key, and a spray mode selection button, supporting the multi-functional use and adjustable settings of the cleaning equipment.
