Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and particularly to a cleaning equipment and its double-suction port structure. Background Art

[0002] Currently, with the development of technology, cleaning equipment such as vacuum cleaners and dust mites removers have become powerful assistants for improving cleaning efficiency and reducing manual labor. Among them, a double-suction port dust mite remover is a dust mite remover provided with two suction ports, a front suction port mainly for adsorbing hair, and a rear suction port for adsorbing dust such as dandruff, dust mites, and debris.

[0003] However, the double-suction port structure of the existing double-suction port dust mite remover is relatively complex, and the manufacturing cost is relatively high. Summary of the Invention

[0004] An object of the present application is to provide a cleaning equipment and its double-suction port structure, which can collect the dust at the two suction ports to the sewage collection port through a shorter path, and has a simple structure and a low manufacturing cost.

[0005] To achieve the above object, the technical solution adopted in the present application is: a double-suction port structure of a cleaning equipment, which includes a housing and an air duct cover. The housing is provided with a first suction port and a second suction port arranged in parallel. A first opening is formed in the middle of the first suction port along its length direction, and a second opening is formed in the middle of the second suction port along its length direction. The first opening and the second opening are arranged in parallel front and back. The air duct cover is provided with a first suction port connected to the first opening, a second suction port connected to the second opening, and a sewage collection port located between the first suction port and the second suction port. A first air flow channel is formed between one side of the sewage collection port and the first suction port, and a second air flow channel is formed between the other side of the sewage collection port and the second suction port.

[0006] As a preference, in the front-back direction, the second opening is arranged on the side of the second suction port away from the first suction port, and the sewage collection port is arranged above the second suction port and on the side of the second suction port close to the first suction port.

[0007] As a preference, the air duct cover is provided with a first guiding surface at the end of the first air flow channel and a second guiding surface at the end of the second air flow channel. The first guiding surface and the second guiding surface are based on the bottom of the air duct cover and extend towards each other while extending towards the sewage collection port.

[0008] As a preference, the width of the first air flow channel gradually decreases from the end close to the first suction port to the end close to the sewage collection port.

[0009] As a preference, the length of the first opening is greater than that of the second opening, and the width of the second opening is greater than that of the first opening.

[0010] As a preference, from both ends in the length direction towards the direction close to the first opening, the depth of the first suction port gradually becomes deeper.

[0011] As a preference, the air duct cover is further provided with an air extraction port and an exhaust port. The air extraction port and the dirt collection port are arranged side by side left and right. The exhaust port is arranged on the side away from the first suction port of the air extraction port in the front - rear direction. A third air flow channel is formed between the air extraction port and the exhaust port.

[0012] As a preference, the third air flow channel is bent and extends to the side of the second air flow channel facing away from the first air flow channel.

[0013] As a preference, the air duct cover is of a split - type structure.

[0014] To achieve the above - mentioned purposes, the technical solution adopted in this application is: a cleaning device, which applies the double - suction - port structure described in any one of the above.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: (1) The dirt collection port is arranged between the first suction port and the second suction port in the front - rear direction, so that the first air flow channel and the second air flow channel can be set shorter, which is beneficial to reducing the distance that dust debris needs to travel from the suction port to the dust cup, making it easier to collect dust debris; (2) Through an air duct cover connected to the housing, the dust debris is transported from the suction port to the dirt collection port, and then transported to the dust cup through the dirt collection port. The entire double - suction - port structure is simple in structure and easy to process and form. Description of the Drawings

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence.

[0024] The terms "comprising" and "having" in the description and claims of the present application and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0025] The present application provides a dual suction port structure for a cleaning device, as Figures 1-4As shown in the figure, it includes a housing 10 and a duct cover 20. A first suction port 11 and a second suction port 12 are arranged in parallel on the housing 10. A first opening 111 is formed in the middle of the first suction port 11 along its own length direction, and a second opening 121 is formed in the middle of the second suction port 12 along its own length direction. The first opening 111 and the second opening 121 are arranged side by side front and back. On the duct cover 20, there are a first suction port 21 connected to the first opening 111, a second suction port 25 connected to the second opening 121, and a dirt collection port 23 located between the first suction port 21 and the second suction port 25. A first air flow channel 22 is formed between one side of the dirt collection port 23 and the first suction port 21, and a second air flow channel 24 is formed between the other side and the second suction port 25. First of all, in the present application, the dirt collection port 23 is arranged between the first suction port 21 and the second suction port 25 in the front-back direction, so that the first air flow channel 22 and the second air flow channel 24 can be set shorter, which is conducive to reducing the distance that dust needs to travel from the suction port to the dust cup, making it easier to collect dust. Moreover, both suction ports are provided with openings in the middle of their length directions to connect with the suction ports, which is conducive to the dust on both sides in the length direction being equally sucked into the duct cover 20. Through the connection between the duct cover 20 and the housing 10, the dust is transported from the suction port to the dirt collection port 23, and then transported to the dust cup through the dirt collection port 23. The structure of the entire dual suction port is simple and easy to process and form.

[0026] In some embodiments, in the front-back direction, the second opening 121 is arranged on the side of the second suction port 12 away from the first suction port 11, and the dirt collection port 23 is arranged above the second suction port 12 and on the side of the second suction port 12 close to the first suction port 11. In other words, the second opening 121 is arranged on the side of the second suction port 12 that is biased towards the rear, and the dirt collection port 23 is arranged above the second suction port 12 and is arranged forward, so as to realize that the dirt collection port 23 is arranged between the first suction port 11 and the second suction port 12 in the front-back direction, and the position of the dirt collection port 23 is relatively rearward for connection with the dust cup.

[0027] In some embodiments, the duct cover 20 is provided with a first guiding surface 221 at the end of the first air flow channel 22 and a second guiding surface 241 at the end of the second air flow channel 24. The first guiding surface 221 and the second guiding surface 241 are based on the bottom of the duct cover 20 and extend towards each other while extending towards the dirt collection port 23 to guide the dust to rise along the guiding surface towards the dirt collection port 23. It can be understood that the first guiding surface 221 and the second guiding surface 241 can specifically be inclined surfaces or curved surfaces. In a specific embodiment, both the first guiding surface 221 and the second guiding surface 241 are curved surfaces.

[0028] In some embodiments, the thickness of the plate body of the air duct cover 20 at the first guiding surface 221 and the second guiding surface 241 is substantially unchanged, so as to save the raw material cost required for the processing and production of the air duct cover 20, which is beneficial to reducing the self-weight of the air duct cover 20. In other words, at the first guiding surface 221 and the second guiding surface 241, grooves can be formed on the back surface through stamping or integral injection molding, so as to achieve the effects of saving materials and reducing the self-weight.

[0029] In some embodiments, the width of the first air flow channel 22 gradually decreases from the end close to the first air suction port 21 to the end close to the dirt collection port 23. This means that the length of the first air suction port 21 is greater than the length of the second air suction port 25, and correspondingly, the length of the first opening 111 is greater than the length of the second opening 121. The first opening 111 is set to be longer so as to suck the dust and debris in the first suction port 11 into the first air flow channel 22, and the first air flow channel 22 gradually narrows to guide the dust and debris to gradually concentrate and pass through the dirt collection port 23.

[0030] In some embodiments, the cleaning device is a dust mite remover. The first suction port 11 is set to be narrower and is mainly used for sucking hair. A roller brush is provided at the second suction port 12 for sucking large particle garbage such as dust mites and debris.

[0031] In some embodiments, the air duct cover 20 is further provided with an air extraction port 26 and an exhaust port 28. The air extraction port 26 and the dirt collection port 23 are arranged side by side left and right for connection with the dust cup. The exhaust port 28 is arranged on the side of the air extraction port 26 far from the first suction port 11 in the front-rear direction for connection with the fan. A third air flow channel 27 is formed between the air extraction port 26 and the exhaust port 28.

[0032] In some embodiments, the length of the first opening 111 is greater than the length of the second opening 121, and the width of the second opening 121 is greater than the width of the first opening 111. By increasing the length or width, the dust and debris are more easily sucked into the air duct cover 20. Since the first suction port 11 is narrower, the first opening 111 increases in length so that the dust and debris in the first suction port 11 are more easily sucked. The second suction port 12 is wider, and the dust and debris at the second suction port 12 can be more easily sucked by increasing the width. Moreover, compared with the way of increasing the length, increasing the width of the second suction port 12 does not need to consider the interference with the air extraction port 26.

[0033] In some embodiments, the first suction port 11 gradually becomes deeper from both ends in the length direction towards the direction close to the first opening 111, so as to guide the dust and debris to move towards the first opening 111 in the middle, making the dust and debris more easily sucked.

[0034] In some embodiments, the third air flow channel 27 is bent and extends to the side of the second air flow channel 24 facing away from the first air flow channel 22, so that the exhaust port 28 can be arranged closer to the central position in the left-right direction of the housing 10, and the exhaust port 28 is more easily connected to a blower arranged in the center.

[0035] In some embodiments, the width of the first air flow channel 22 gradually decreases from the end close to the first suction port 21 to the end close to the dirt collection port 23. Specifically, it is arranged that: one end of the first suction port 21 along its own length direction relatively far from the air extraction port 26, the side of the dirt collection port 23 far from the air extraction port 26, and one end of the second suction port 25 along the length direction far from the air extraction port 26 are flush in the front-back direction, and the other end of the first suction port 21 along its own length direction extends to the front of the air extraction port 26.

[0036] In some embodiments, the air duct cover 20 is of a split structure and is formed by buckling an upper cover shell and a lower cover shell up and down. The split setting makes the air duct cover 20 easier to be processed and formed.

[0037] This application can also provide a cleaning device, which applies the double suction port structure described above, and can specifically be a mite remover or a vacuum cleaner. The cleaning device has the characteristics that dust and debris at the two suction ports can be collected into the dirt collection port 23 through a shorter path simultaneously, and the structure is simple and the processing and manufacturing cost is low.

[0038] The above describes the basic principles, main features and advantages of this application. Those skilled in the art of this industry should understand that this application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of this application. Without departing from the spirit and scope of this application, this application will have various changes and improvements, and these changes and improvements all fall within the scope of this application claimed. The scope of protection required by this application is defined by the appended claims and their equivalents.
