Description

Technical Field

[0001] This invention relates to a pole-type cleaning assembly and its vacuum cleaner, belonging to the field of small household appliance manufacturing technology. Background Technology

[0002] The prior application CN104768439A discloses a moisture-absorbing attachment that connects to a dry vacuum cleaner for cleaning purposes. This application expands the application scope of dry vacuum cleaners. However, firstly, the moisture-absorbing attachment is for direct handheld use, with a limited operating radius. It is only suitable for work surfaces that are high, such as desktops. If cleaning the floor, the user needs to squat down to operate it, which is inconvenient. Secondly, the suction head of the moisture-absorbing attachment has a single function, which can only achieve simple water suction. It cannot be expanded with additional cleaning attachments, which creates an obstacle to cleaning large areas and deep surfaces. Summary of the Invention

[0003] The technical problem to be solved by this invention is to address the shortcomings of existing technologies by providing a stick-type cleaning assembly and a vacuum cleaner thereof. This invention fully utilizes the characteristic that traditional vacuum cleaners require the use of an extension tube, integrating the air duct, solution tank, and recovery tank into a stick-type cleaning assembly, replacing the existing extension tube. By leveraging the slender advantage of the stick-type cleaning assembly, the capacity of the solution tank and recovery tank is maximized. Using the stick-type cleaning assembly in conjunction with a handheld vacuum cleaner greatly expands the functionality of the vacuum cleaner, resulting in a simple structure and convenient, lightweight operation.

[0004] The technical problem to be solved by the present invention is achieved through the following technical solution:

[0005] A pole-type cleaning assembly includes a pole body, the pole body including a suction tube for connecting to the suction port of a floor brush, a collection bucket for collecting wastewater, and a solution bucket for providing cleaning liquid. The upper end of the pole body is provided with a main unit connector, and the lower end is provided with a floor brush connector.

[0006] Furthermore, the outer surfaces of the recycling tank and the solution tank constitute at least a portion of the outer surface of the rod.

[0007] As needed, the straw is positioned at the center of the rod, and the recycling bin and solution bin surround the front and rear sides of the straw to form the rod; for easy cleaning and replacement, the recycling bin and solution bin are detachable.

[0008] Furthermore, the rod also includes a separation chamber disposed above and connected to the recycling bin, the separation chamber being equipped with a gas-water separation device; according to the flow direction of the solid-liquid mixed gas, the upstream of the separation chamber is connected to the water outlet of the suction pipe, and the downstream is connected to the main unit connector.

[0009] To facilitate processing and reduce costs, the separation chamber and the recycling bin are integrally molded.

[0010] In addition, the solution tank includes a water inlet and a water outlet. The water outlet is equipped with a water outlet valve and a water outlet pipe in sequence, and the water outlet pipe is connected to the floor brush.

[0011] In order to effectively control the volume of waste liquid, the recycling bin is equipped with a water level sensing device, including: a water level sensing circuit board installed in the rod body, a Hall switch fixed on the inner wall of the recycling bin, and a magnet installed in the water level float. The water level float floats on the liquid surface in the recycling bin.

[0012] The present invention also provides a vacuum cleaner, mainly comprising a main body and a floor brush connected thereto. The main body includes a body and a dust cup connected to the body. The dust cup is provided with a suction pipe. The body is provided with a vacuum source that generates suction and a battery that powers the vacuum source.

[0013] Furthermore, the axis of the battery is parallel to the axis of the handle.

[0014] In summary, this invention provides a stick-type cleaning assembly and a vacuum cleaner thereof. This invention fully utilizes the characteristic that traditional vacuum cleaners require the use of an extension tube, integrating the air duct, solution tank, and recovery tank into a stick-type cleaning assembly, replacing the existing extension tube. By leveraging the slender advantage of the stick-type cleaning assembly, the capacity of the solution tank and recovery tank is maximized. Using the stick-type cleaning assembly in conjunction with a handheld vacuum cleaner greatly expands the functionality of traditional dry vacuum cleaners. It has a simple structure and is lightweight and convenient to use.

[0015] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0021] Figure 1 This is a schematic diagram of the overall structure of the rod-type cleaning assembly of the present invention; Figure 2 This is a cross-sectional view of the rod-type cleaning assembly of the present invention; Figure 3 This is a partial cross-sectional view of the top structure of the rod-type cleaning assembly of the present invention. Figures 1 to 3 As shown, this invention provides a rod-type cleaning assembly, including a rod body 100. The rod body 100 includes a suction tube 110 for connecting to the suction port of a floor brush (not shown), a wastewater collection tank 120, and a solution tank 130 for providing cleaning liquid. The upper end of the rod body 100 is provided with a main unit connector 200 for connecting to a main unit, which has a vacuum source that generates suction. The lower end of the rod body 100 is provided with a floor brush connector 300 for connecting the suction tube and the floor brush. To facilitate arrangement and make the rod structure more compact, the outer surfaces of the collection tank 120 and the solution tank 130 constitute at least a portion of the outer surface of the rod body, such as... Figure 1 As shown, the straw 110 is positioned at the center of the rod 100, and the recycling bin 120 and solution bin 130 are respectively positioned on the front and rear sides of the straw 110, surrounding the straw 110 to form the rod. This design utilizes the length of the rod 100 to maximize the capacity of the recycling bin 120 and solution bin 130. Depending on different installation requirements, the solution bin 130 and recycling bin 120 can be integrated into the rod 100 or installed separately. For ease of water addition and cleaning, the solution bin 130 and recycling bin 120 can be detachably mounted on the front and rear sides of the straw 110 to form the rod 100. Figure 2 and Figure 3 As shown, the rod body 100 also includes a separation chamber 140 disposed above and communicating with the recycling bin 120. The separation chamber is equipped with a gas-liquid separator 400. Following the flow direction of the solid-liquid mixture, the upstream of the separation chamber is connected to the water outlet 111 of the suction pipe 110, and the downstream is connected to the vacuum source of the vacuum cleaner's main unit via the main unit connector 200. The gas-liquid separator 400 disposed in the separation chamber 140 is used to improve the gas-liquid separation efficiency. Alternatively, a water-blocking and breathable component, such as a water-filtering HEPA filter, can be used instead of the gas-liquid separator 400. If a water-filtering HEPA filter is used instead of the gas-liquid separator, the HEPA filter can be disposed above the recycling bin, and the suction pipe outlet can be directly connected to the recycling bin; the separation chamber may not be necessary. In this embodiment, the separation chamber 140 and the recycling bin 120 can be integrally formed, or they can be independently disposed according to structural requirements. See also... Figure 5As shown, in order to facilitate water addition, a water inlet is provided at the top of the solution tank 130, and a water outlet is provided at the bottom of the solution tank 130. A water outlet valve 131 and a water outlet pipe 132 are provided at the water outlet in sequence. Under the sealing effect of the water outlet valve 131, the water outlet will not leak when the solution tank 130 is lifted alone. The water outlet pipe 132 is connected to the floor brush 2000.

[0022] like Figure 2 and combined Figure 3 As shown, to effectively control the amount of waste liquid in the recycling bin, a water level sensing device 500 is installed inside the recycling bin. This device includes: a water level sensing circuit board (PCB) installed inside the rod 100, a Hall switch 501 fixed to the inner wall of the recycling bin 120, and a magnet 503 correspondingly installed in a water level float 502. The water level float 502 floats on the liquid surface inside the recycling bin 120. The water level sensing device works as follows: the water level float 502 rises along with the water level in the recycling bin 120. When it rises to a designated height, the Hall switch 501 on the inner wall of the recycling bin 120 senses that the height of the magnet 503 in the water level float 502 has reached the designated height, and then releases a signal to the water level sensing PCB to control the power cut-off. At this time, the user can remove the recycling bin 120 and empty the waste liquid inside. Since this part is prior art, more detailed descriptions are not provided here.

[0023] As can be seen from the above, this invention fully utilizes the characteristic that traditional vacuum cleaners require the use of extension tubes, integrating the air duct, solution tank, and recovery tank into a single rod-type cleaning component to replace the extension tube combination; at the same time, it takes advantage of the slender shape of the rod-type cleaning component to maximize the capacity of the solution tank and recovery tank; it not only adds extra functionality to the vacuum cleaner but also does not take up extra space, thus expanding the application range of dry vacuum cleaners.

[0024] Figure 4 This is a schematic diagram of the connection structure between the pole-type cleaning component and the handheld vacuum cleaner of the present invention; Figure 5 This is a schematic diagram of the connection structure between the rod-type cleaning assembly and the floor brush of the present invention. Figure 4 and combined Figure 5As shown, the present invention also provides a vacuum cleaner. In this embodiment, the vacuum cleaner is a handheld vacuum cleaner, mainly including a main body 1000 and a floor brush 2000 connected thereto. The main body 1000 includes a body 1001 and a dust cup 1002 connected to the body 1001. The dust cup 1002 is provided with a suction tube 1003 for connecting the floor brush 2000 to the main body 1000. The body contains a vacuum source that generates suction and a battery that powers the vacuum source. A handle 1004 is provided on one side of the body 1001 for easy gripping by the user. The dust cup 1002 contains an airflow filtering device. Preferably, the axis of the battery and the axis of the handle 1004 are substantially parallel to each other. Figures 1 to 3 As shown, the vacuum cleaner also includes the stick-type cleaning assembly described above. The main unit connector 200 is connected to the suction pipe 1003, and the floor brush connector 300 is connected to the floor brush 2000. The connectors at the upper and lower ends of the stick-type cleaning assembly are respectively connected to the handheld vacuum cleaner body and the floor brush, forming an electrical connection. The handheld vacuum cleaner body supplies power to the floor brush. Figure 5 As shown, the floor brush 2000 is equipped with an electronic pump connected to the water outlet pipe 132. The handheld vacuum cleaner body is equipped with a button (not shown in the figure) to control the electronic pump, which controls the spraying of cleaning fluid. Of course, the electronic pump can also be set on the stick cleaning assembly, depending on actual needs. In the specific embodiment, this invention only describes the physical connection structure in detail. The electrical connection method between the stick cleaning assembly and the handheld vacuum cleaner to be connected is a conventional choice for those skilled in the art and will not be described in detail here.

[0025] Combination Figures 2 to 5 As shown, the working process of this invention is as follows:

[0026] First, the stick cleaning assembly needs to be installed on the vacuum cleaner, replacing the existing extension tube. Second, the cleaning solution in the solution tank 130 is output to the surface to be cleaned or the floor brush through the water outlet 132 under the action of the water outlet valve 131. Under the action of the floor brush 2000, the mixture of wastewater and air flows into the separation chamber 140 through the water outlet 111 at the upper end of the suction tube 110. Under the action of the air-water separator 400, it rotates at high speed. Under the action of centrifugal force and gravity, the water carries some dust particles and falls from the inlet 121 into the collection bin 120. The airflow enters the handheld vacuum cleaner body 1000 through the channel of the air-water separator 400. The flow of the mixture of wastewater and air in the vacuum cleaner is as follows. Figure 3 As indicated by the arrow in the diagram; in addition, as the waste liquid in the recycling bin 120 increases, when the water level sensor 500 senses that the bin is full, the machine will stop working. At this time, the user can remove the recycling bin 120 and empty it for later use.

[0027] As can be seen from the above, existing handheld vacuum cleaners are originally dry vacuum cleaners. By replacing their extension tubes with the rod-type cleaning assembly of the present invention, a solution tank is added, which can output cleaning liquid to the surface to be cleaned with stubborn stains and perform further cleaning operations.

[0028] It should be noted that the stick cleaning assembly provided by the present invention is not limited to use only with handheld vacuum cleaners as described above, but can also be used in combination with other types of dry vacuum cleaners, such as traditional canister vacuum cleaners, to achieve the cleaning function.

[0029] In summary, this invention fully utilizes the characteristic that traditional vacuum cleaners require the use of an extension tube, integrating the air duct, solution tank, and recovery tank into a stick-type cleaning assembly, replacing the existing extension tube. By taking advantage of the slender shape of the stick-type cleaning assembly, the capacity of the solution tank and recovery tank is maximized. The use of the stick-type cleaning assembly in conjunction with a handheld vacuum cleaner greatly expands the functionality of traditional dry vacuum cleaners. It has a simple structure and is lightweight and convenient to use.
