Description

A handheld electric cleaner Technical Field

[0001] The utility model relates to a cleaner, in particular to a handheld electric cleaner. Background Art

[0002] In daily life, when the surface of a fabric sofa is stained with sewage, if it is wiped directly with a rag, the sewage will more easily penetrate the fabric material to form stains. Therefore, a handheld electric cleaner specially used for electric water suction is launched on the market to solve the above problem. Its structure is mainly composed of a shell, a motor and a battery inside the shell, and a sewage tank outside the shell. The sewage tank is provided with a water suction port and an air outlet. The sewage tank is provided with a water suction channel respectively connected to the water suction port and the air outlet. The air outlet of the sewage tank is sealed and connected to the air suction port of the motor, and provides negative pressure suction for the water suction channel, and then the sewage can be sucked out of the negative pressure suction. The water suction port sucks the water into the sewage tank, that is, the sewage is directly removed from the surface of the fabric sofa; however, the water suction channel of these existing handheld electric cleaners is only a simple straight-through channel. Since the suction path is too short and particularly simple, some water vapor is easily sucked directly into the suction port in actual use, corroding the internal components of the motor, thereby greatly affecting the reliability of the handheld electric cleaner and shortening the service life; at the same time, the motor of the existing handheld electric cleaner is vertically installed at the rear of the shell, while the sewage tank is installed at the front of the shell. This structure has a poor overall layout and has defects such as bulky size and ugly appearance. Utility Model Content

[0024] A handheld electric cleaner, as shown in Figures 1 to 3, can be used to electrically absorb sewage from the surface of a fabric sofa, and can also be used to remove sewage from the surface of other objects. Its structure mainly consists of a shell 1, a motor 3 and a battery 4 inside the shell, and a sewage tank 2 outside the shell. In this embodiment, the left side of the view shown in Figure 1 is used as the front of the handheld electric cleaner, and the right side of the view is used as the rear of the handheld electric cleaner.

[0025] The motor 3 is installed horizontally at the front of the shell 1. Specifically, a front sealing ring 32 is provided at the front of the motor 3, and a rear sealing ring 33 is provided at the rear of the motor. The motor 3 is sealed and installed in the shell 1 through the front and rear sealing rings, and an exhaust port 34 of the motor is provided on the side of the front of the shell; the rear of the shell 1 forms a handle for hand holding, and the rear of the handle is provided with a motor switch 11 for starting the motor 3 and a charging port 12 for charging the battery 4, and the battery 4 is also installed horizontally in the handle; obviously, through such a position layout, the compactness of the structural design is guaranteed, making the volume more compact, and the beauty of the appearance design is guaranteed.

[0026] The sewage tank 2 is made of transparent plastic material so that the user can directly view the sewage capacity and facilitate subsequent cleaning. The water tank 2 is detachably configured at the bottom of the shell 1 and is flush with the length of the shell, thereby ensuring the maximum usable volume without affecting the compactness of the overall appearance. A detachable cleaning brush 8 is also provided at the bottom of the sewage tank 2, which can be used to brush away stubborn stains when they appear on the surface of an object. The detachable structure of this embodiment uses an elastic buckle to detachably buckle the cleaning brush 8 in the mounting groove on the bottom surface of the sewage tank 2.

[0027] The sewage tank 2 is provided with a water suction port 512 and an air outlet 72. A water suction channel is provided in the sewage tank 2, which is connected to the water suction port 512 and the air outlet 72 respectively. The water suction channel is composed of a rear channel 5, a middle channel 6 and a front channel 7 which are connected in sequence.

[0028] The rear channel 5 includes a water suction pipe 51 vertically arranged on the bottom surface of the sewage tank 2 and side plates 52 arranged on the top surface of the sewage tank 2 and located on both sides of the water suction pipe 51. In this embodiment, as shown in Figure 1, the water suction pipe 51 extends upward directly from the inner bottom surface of the sewage tank 2 to form a connected structure, while the side plates 52 extend downward directly from the inner top surface of the sewage tank 2 to form a connected structure. An axially extending water suction hole 511 is provided in the water suction pipe 51, and the lower end of the water suction hole passes through the bottom surface of the sewage tank 2 to form a water suction port 512. A water suction gap 521 is formed between the side plate 52 and the water suction pipe 51; in this way, the rear channel 5, as shown by the arrow in Figure 2, can form an inverted U-shaped trajectory channel by the water suction port 512, the water suction hole 511 and the water suction gap 521 connected in sequence.

[0029] Of course, the number of rear channels 5 can be designed according to actual conditions. For example, in the present embodiment, two groups of rear channels 5 are provided, which are arranged side by side and interconnected. Each group of rear channels 5 has a water suction port 512 formed through the bottom surface of the sewage tank 2 to form an independent water suction port. The water suction port can be designed as a long hole to facilitate the rapid suction of sewage.

[0030] The middle channel 6 is formed by horizontally and sequentially setting a plurality of vertical partitions 61 in the middle of the sewage tank 2, thereby forming a cavity 62 between each two adjacent partitions, and each two adjacent cavities are connected through the gap 63 at the top of the partition 61. In fact, the gap 63 between each two adjacent cavities 62 and the top of the partition 61 between the cavities is also as shown by the arrow in Figure 2, forming an inverted U-shaped trajectory channel.

[0031] The number of the compartments 62 can be determined according to the actual design. For example, in the present embodiment, two compartments 62 are arranged side by side, and each compartment 62 is provided with a baffle 64. The baffle is a horizontal plate integrally formed in the middle of the partition 61, and is arranged on the front side of the compartment, that is, in the middle of the partition 61 on the left side of the compartment as shown in FIG1 ; in this way, the flow of the gap 63 between adjacent compartments 62 is not blocked, and the sewage in the sewage tank 2 is prevented from being easily sucked into the next compartment 62, so that the sewage can be more effectively blocked and stored in the sewage tank 2.

[0032] The front channel 7 is a U-shaped tube 71 arranged in the sewage tank 2. The side channel 21 is formed between the U-shaped tube and the inner wall of the sewage tank 2. One end of the U-shaped tube 71 passes through the top surface of the sewage tank 2 to form an air outlet 72, and the other end of the U-shaped tube 71 is connected to the side channel 21.

[0033] In this way, the compartment 62 at the rear end of the middle channel 6 is directly connected to the rear channel 5 , and the compartment 62 at the front end of the middle channel 6 is connected to the front channel 7 via the side channel 21 .

[0034] The outer surface of the sewage tank 2 is also provided with a disassembly button 22 and several color-coded labels 23. The disassembly button 22 facilitates quick removal of the sewage tank 2 from the bottom of the housing 1. The labels 23 allow the user to intuitively distinguish the water levels in the various chambers within the sewage tank 2. As shown in FIG3 of this embodiment, three colors of labels 23 are provided: the chamber containing the front channel 7 is marked with a red label 23, the chamber in front of the middle channel 6 is marked with a yellow label 23, and the chambers behind the middle channel 6 and the chambers containing the rear channel 57 are marked with a green label 23. Of course, the color, form, or size of these labels 23 are not limited. Thus, the user can better understand the water level status of each chamber through the labels 23 and take timely action when the water level reaches the warning level. In actual operation, when water is present in the chamber containing the front channel 7, which is affixed with a red label 23, it is determined that the water level is too high and the sewage tank 2 can be cleaned.

[0035] The shell 1 is provided with an air suction channel 9, which is connected to the air suction port 31 of the motor 3 and the air outlet 72 of the sewage tank 2 respectively. That is, the air outlet 72 of the sewage tank is sealedly connected to the air suction port 31 of the motor, thereby providing negative pressure suction in the water suction channel 9.

[0036] The air outlet 72 is provided with an embedded and fixed sealing plug 10, and the air outlet 72 is sealed and connected with the air suction channel 9 through the sealing plug 10. As shown by the arrow in Figure 2, the air suction channel 9 is a "┏"-shaped channel composed of a vertical channel 91 connected to the air outlet 72 and a horizontal channel 92 connected to the air suction port 31.

[0037] Therefore, the suction path of the water suction channel is lengthened by the rear channel 5, the middle channel 6 and the front channel 7, and the design of the air suction channel 9 is combined with the internal structure of the rear channel 5, the middle channel 6 and the front channel 7. At the same time, a unique design is also made to the internal structure of the rear channel 5, the middle channel 6 and the front channel 7, so as to better prevent the water vapor in the sewage tank 2 from being directly sucked into the air suction port 31 and corroding the internal components of the motor 3, thereby ensuring the reliability of the handheld electric cleaner and extending its service life.

[0038] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included in the protection scope of the present invention.
