Description

Handheld electric cleaning machine Technical Field

[0001] This utility model relates to a cleaning machine for cleaning dirt from the surface of items, namely a handheld electric cleaning machine. Background Technology

[0002] Currently, dirt adhering to the surface of fabric sofas and other items can be removed using a handheld electric washer. The specific process is as follows: first, wet the dirt with water and use a cleaning brush to remove the dirt from the surface of the item, creating wastewater. Then, turn on the handheld electric washer and aim the suction port at the wastewater, which will be sucked into the wastewater tank of the handheld electric washer for temporary storage. Traditional handheld electric washer suction ports are located at an angle at the front of the machine, and then connected to the wastewater chamber through a bent suction channel inside the machine. In actual use, it has been found that because the distance between the suction port and the wastewater tank is too long, the wastewater cannot be sucked into the wastewater tank quickly, effectively, and smoothly. At the same time, when the handheld electric washer is in the off state, if the user holds the handheld electric washer vertically, some wastewater in the wastewater tank will often backflow and drip from the suction port, which greatly affects normal use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a handheld electric cleaning machine that can both quickly, efficiently and smoothly suck sewage into the sewage tank and prevent sewage in the sewage tank from backflowing and dripping from the suction port.

[0004] The technical problem of this utility model is solved by the following technical solution:

[0005] A handheld electric cleaning machine includes a body and a wastewater tank mounted on the body. The body is equipped with a vacuum motor, which is sealed to the wastewater tank via a suction channel and provides vacuum negative pressure. A suction pipe is provided on the side of the wastewater tank. The lower end of the suction pipe extends downward at an angle and has a suction port. The upper end of the suction pipe has a discharge port that communicates with the inside of the wastewater tank, and a one-way valve is provided at the discharge port.

[0006] The one-way valve is a duckbill-shaped flat drain pipe that extends into the sewage tank, and the drain pipe has a V-shaped drain cavity inside.

[0007] The large V-shaped opening of the sewage discharge chamber is connected to the sewage outlet, while the small V-shaped opening is suspended inside the sewage tank.

[0008] The sewage tank has a mounting hole on its side, and the upper end of the suction pipe is connected to the outer side of a cover. The inner side of the cover has a drain port and a one-way valve. The cover is installed on the side of the sewage tank, and the one-way valve extends into the sewage tank through the mounting hole.

[0009] The bottom surface of the wastewater tank is equipped with a cleaning brush.

[0010] The bottom surface of the wastewater tank is provided with an installation groove, and the cleaning brush is detachably mounted in the installation groove via a brush plate.

[0011] The wastewater tank is detachably installed at the bottom of the machine body, and a detachment button is provided on the wastewater tank.

[0012] The sewage tank is provided with several partitioned chambers arranged in sequence along the horizontal direction and connected to each other. The one-way valve extends into the partitioned chamber at the front end of the sewage tank through the mounting hole. The vacuum motor is connected to the partitioned chamber at the rear end of the sewage tank through the air intake channel.

[0013] The machine body is equipped with a battery pack that powers the vacuum motor, and the machine body is equipped with a switch on the outside that controls the opening and closing of the vacuum motor.

[0014] Compared with the prior art, the main feature of this utility model is that a suction pipe is provided on the side of the sewage tank. The lower end of the suction pipe extends downwards and has a suction port. The upper end of the suction pipe has a discharge port that communicates with the inside of the sewage tank, and a one-way valve is provided at the discharge port. In this way, since the suction port is directly connected to the sewage tank, the sewage can be directly sucked into the sewage tank and stored by activating the handheld electric washer and pointing the suction port at the surface of the object. This allows the sewage to be sucked into the sewage tank quickly, efficiently and smoothly. At the same time, the one-way valve design does not affect the sewage suction into the sewage tank, and at the same time prevents the sewage in the sewage tank from entering the discharge port when the handheld electric washer is in the off state. Therefore, even if the user holds the handheld electric washer vertically, no sewage in the sewage tank will backflow and drip from the suction port, thus ensuring the normal use of the handheld electric washer.

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] As shown in Figures 1 to 4, the handheld electric cleaning machine is a small cleaning appliance used to clean and remove dirt adhering to the surface of items such as fabric sofas. Its structure includes a body 1 and a wastewater tank 2 that is detachably snapped onto the bottom of the body. That is, the entire cleaning machine adopts an upper and lower separated structure design, which ensures that there is enough installation space inside the body 1 and allows the wastewater tank 2 to be designed with a larger storage volume. The wastewater tank 2 is also equipped with a press-type disassembly button 23 to facilitate the disassembly and assembly of the wastewater tank 2 from the bottom of the body 1.

[0024] The machine body 1 is equipped with a battery pack 6 and a vacuum motor 5. The battery pack is a rechargeable battery pack to power the vacuum motor. A switch 7 is provided on the front side of the machine body 1, that is, the left side of the machine body shown in Figure 1, which can be used to control the opening and closing of the vacuum motor 5.

[0025] The machine body 1 has multiple exhaust holes 12 on both sides for exhausting the vacuum motor 5 when it is working. The vacuum motor 5 can be sealed and connected to the sewage tank 2 through a U-shaped suction channel 11 inside the machine body 1, and provide vacuum negative pressure inside the sewage tank.

[0026] The bottom surface of the sewage tank 2 is provided with a cleaning brush 8. Specifically, the bottom surface of the sewage tank 2 is provided with an installation groove 22, and the cleaning brush 8 is detachably fastened and installed in the installation groove 22 through the brush plate 81. The purpose of this structure is to facilitate the installation of the cleaning brush 8 and the removal of dirt, and to allow for quick disassembly of the cleaning brush 8 for easy individual cleaning.

[0027] The sewage tank 2 is provided with a suction pipe 3 on its side. Usually, the suction pipe is set on the front side of the sewage tank 2, that is, the left side of the sewage tank as shown in Figure 1. The suction pipe 3 is a flat pipe, and the lower end of the suction pipe 3 extends obliquely downward and is provided with a suction port 31. The position of the suction port is preferably lower than the bottom surface of the sewage tank 2, so that the suction port 31 can easily fit the dirt on the surface of the item for better suction. The upper end of the suction pipe 3 is provided with a drain port 32 that communicates with the inside of the sewage tank 2, and a one-way valve 4 is provided at the drain port.

[0028] The suction pipe 3 is equipped with a V-shaped suction channel 33 with a large suction port 31 and a small discharge port 32, which enables the suction pipe 3 to form a suction capacity with the largest area and the largest suction force.

[0029] The one-way valve 4 can be selected from various structures with one-way passage. As shown in Figure 1, the one-way valve is designed as a duckbill-shaped drain pipe 41 that extends into the sewage tank 2. In actual use, a check valve structure similar to that in pipeline valves can also be used as a one-way valve, or a one-way diaphragm can be used to block the drain outlet 32 ​​to achieve the function of a one-way valve.

[0030] Meanwhile, the suction pipe 3 and the one-way valve 4 can be designed as a single unit on the front side of the sewage tank 2, or they can be designed separately to facilitate the separate manufacturing of the suction pipe 3 and the one-way valve 4, as shown in Figures 5 and 6. The side of the sewage tank 2 needs to be provided with a flat mounting hole, and the upper end of the suction pipe 3 is connected to the outer side of a cover 9. This connection is usually made in one piece. The inner side of the cover 9 is provided with a drain port 32 and a one-way valve 4. In this way, it is only necessary to install the cover 9 on the side of the sewage tank 2 and let the one-way valve 4, that is, the drain flat pipe 41, pass through the mounting hole and extend into the sewage tank 2.

[0031] Furthermore, the drain flat pipe 41 is provided with a drain chamber 42 with a V-shaped cross-section, and the large V-shaped opening of the drain chamber is connected to the drain outlet 32, while the small V-shaped opening is suspended in the sewage tank 2. This allows the sewage to enter the sewage tank 2 quickly and smoothly, while preventing the sewage in the sewage tank from flowing back into the drain chamber 42.

[0032] The sewage tank 2 is provided with several partitioned cavities 21 arranged in sequence along the horizontal direction and connected to each other. The sewage tank 2 can be made of transparent material so that users can observe the sewage storage status inside in real time.

[0033] The one-way valve 4 extends through the mounting hole into the partition chamber 21 at the front end of the sewage tank, while the vacuum motor 5 is sealed and connected to the partition chamber 21 at the rear end of the sewage tank through the suction channel 11. Therefore, the design of the partition chamber will not allow sewage to be accidentally sucked into the vacuum motor 5, and will allow sewage to be stored stably in the sewage tank 2.

[0034] Obviously, since the suction port 31 is directly connected to the sewage tank 2, when the handheld electric washer is turned on and the suction port 31 is aimed at the surface of the object, the sewage can be directly sucked into the sewage tank 2 for storage. In other words, the sewage can be sucked into the sewage tank 2 quickly, efficiently and smoothly. Moreover, the design of the one-way valve 4 will not affect the sewage suction into the sewage tank, and at the same time prevent the sewage in the sewage tank from entering the drain port 32 when the handheld electric washer is in the off state. Therefore, even if the user holds the handheld electric washer vertically, some sewage in the sewage tank 2 will not backflow and drip from the suction port 31, thus ensuring the normal use of the handheld electric washer.

[0035] The embodiments described above are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
