Description

TECHNICAL FIELD

[0001] This invention generally relates to the technical field of cleaning equipment, and more particularly, to a cleaning device.

BACKGROUND

[0002] Cleaning devices such as steam mops and handheld steam cleaning machines are extensively used. For example, push-rod steam mops are capable of performing steam cleaning on bare floors, while handheld steam cleaning machines are capable of performing steam cleaning on surfaces such as ceramic tile walls, working tables and cook tops. Presently, cold air and hot air discharged by the suction motor of the conventional cleaning device are mixed, leading to the failure of discharging hot air in time and disordered flowing of hot air in the housing due to the excessive discharge of cold air. Under such circumstances, the temperature of components such as a power panel in the housing may increase sharply, which affects the functional life of components. Chinese patent CN110093889A discloses a cleaning device, wherein the cleaning device is provided with a housing, the housing is provided with an air suction port and an air outlet, and a suction pipe is connected to the air suction port. Obviously, hot air and cold air discharged from the air outlet of the aforesaid cleaning device are mixed. Due to the large quantity of discharged cold air, the hot air cannot be discharged in time, resulting in the temperature rise of components in the housing and the shortening of the functional life of components.

SUMMARY

[0003] The purpose of the present invention is to provide a cleaning device. According to the present invention, cold air and hot air discharged by the suction assembly can be respectively discharged via the air guide assembly and the air outlet assembly, so that the problem that hot air cannot be discharged in time and flows disorderly in the housing is solved.

[0004] To achieve the above purpose, the present invention adopts the following technical solution: a cleaning device comprises a handle assembly, a housing and a power panel assembly arranged in the housing, wherein the cleaning device further comprises a suction assembly, an air guide assembly, and an air outlet assembly, wherein the suction assembly is arranged in the housing, wherein the suction assembly is provided with a first air suction port, a hot air exhaust port, and a cold air exhaust port, wherein the first air suction port is configured to communicate with the handle assembly to suck dirt, wherein the air guide assembly is arranged in the housing, wherein the air guide assembly comprises a hot air channel and a cold air channel arranged independent of each other, wherein the hot air channel is in communication with the hot air exhaust port, and the cold air channel is in communication with the cold air exhaust port, wherein the air outlet assembly is arranged on a base of the housing, wherein the air outlet assembly is provided with a hot air chamber and a cold air chamber arranged independent of each other, wherein air outlets corresponding to the hot air chamber and the cold air chamber are formed on the base, wherein an air outlet of the hot air channel is in communication with the hot air chamber, and an air outlet of the cold air channel is in communication with the cold air chamber, so that hot air and cold air discharged by the suction assembly are respectively discharged through the air outlets on the base. The cleaning device allows the cold air and hot air discharged by the suction assembly to be respectively discharged via the air guide assembly and the air outlet assembly, so that the problem that hot air cannot be discharged in time and flows disorderly in the housing is solved.

[0005] In another embodiment of the present invention, the base comprises a bottom plate and an air outlet cover plate, wherein a part of the air outlets of the base are formed on the air outlet cover plate. The air outlet cover plate is obliquely arranged for guiding the air to flow towards a side facing away from the power panel assembly.

In this way, the air discharged from the hot air exhaust port and the cold air exhaust port of the suction assembly is discharged through the air outlets on the bottom plate and the air outlet cover plate, which significantly increases the area of air outlets while allowing the air to be discharged as soon as possible.

[0009] In another embodiment of the present invention, the air outlet direction of the air outlets arranged on the bottom plate is a first direction, and the air outlet direction of the air outlets on the air outlet cover plate is a second direction perpendicular to the first direction. The first direction is a direction perpendicular to the bottom plate. In this way, the air is blown out in different directions, thereby further increasing the quantity of discharged air while enabling the air to be rapidly discharged.

[0010] In another embodiment of the present invention, the air outlet assembly comprises a shell, a partition plate is arranged in the shell, and the partition plate partitions the inner chamber of the shell into a hot air chamber and a cold air chamber. By means of the arrangement of the partition plate, the hot air chamber and the cold air chamber are formed, achieving a simple and compact structure.

[0011] In another embodiment of the present invention, an upper end of the shell is provided with a first air inlet and a second air inlet. The outlet of the hot air channel communicates with the hot air chamber through the first air inlet, and the outlet of the cold air channel communicates with the cold air chamber through the second air inlet. The aforesaid structure is compact, and the design is reasonable.

[0012] In another embodiment of the present invention, the shell is integrally formed with the base. In this way, the relationship between relative positions of the shell and the base is ensured, and the structural stability is improved.

[0013] In another embodiment of the present invention, the air outlet cover plate is pivotally connected to the bottom plate, which allows the air outlet cover plate to rotate relative to the bottom plate. The pivoting of the air outlet cover plate is capable of changing the discharged air quantity of the air outlets on the base, thereby facilitating the adjustment of the discharged air quantity.

[0014] Compared with the prior art, the present invention has the following advantages: hot air discharged from the hot air exhaust port of the suction assembly is discharged by means of the hot air channel and the hot air chamber, and cold air discharged from the cold air exhaust port of the suction assembly is discharged by means of the cold air channel and the cold air chamber; the hot air channel and the cold air channel are arranged independent of each other, and the hot air chamber and the cold air chamber are arranged independent of each other as well; in this way, cold air and hot air discharged by the suction assembly are respectively discharged through the air guide assembly and the air outlet assembly without being mixed; through adopting the aforesaid design, the prior problem relating to the failure of discharging the hot air in time due to the large quantity of discharged cold air is solved, which effectively prevents the temperature rise of components such as the power panel assembly caused by disordered flowing of hot air in the housing.
