Description

Hand-held vacuum cleaner

Technical field

The utility model relates to a hand-held vacuum cleaner, belonging to the technical field of mechanical dust removal.

Background technique

At present, vacuum cleaners have entered thousands of households as a household cleaning appliance. Among them, the hand-held vacuum cleaner has the advantages of compact size, portability and ease of use, and is more suitable for cleaning a small space, and thus has been favored by the public.

In the prior art, a hand-held vacuum cleaner includes an elongated body having an air inlet, a suction duct, and a dust bag for separating the dirt and dust from the air flow. A motor and fan assembly is provided in the body together with the power source. The handle is located on the upper part of the handheld vacuum cleaner. The handle extends parallel to the elongated body at a small angle to the suction conduit, and both the flow generator and the power source are below the handle within the body.

U.S. Patent No. 1,871, 624 discloses another handle arrangement having a cylindrical body and a handle disposed at one end, the curved suction conduit being located at an end opposite the handle; the handle being disposed across the longitudinal axis of the cylindrical body and generally Parallel to the suction line. The structure can provide the user with a strong wrist position when in use. However, when the vacuum cleaner is in use, its heavy components (such as the motor and fan assembly) are in front of the handle relative to the user's hand, with the result that the user has to exert additional effort to maintain the handheld vacuum cleaner in a fixed orientation. Therefore, the user feels tired and uncomfortable.

In view of the above technical problem, Chinese Patent No. CN101489458B discloses a cleaning device including a suction duct; a flow generator for generating a flow of air flowing along the suction duct; and a separating device communicating with the suction duct to Separating dirt and dust from the airflow; a handle for enabling a user to operate the handheld cleaning device, the handle having a first end, a second end, and a longitudinal axis; and, disposed adjacent to the handle a second end power source for supplying power to the airflow generator; the airflow generator being disposed directly adjacent the first end of the handle, the longitudinal axis passing through at least a portion of the airflow generator, the handle Located between the airflow generator and the power supply. With the above configuration, when the user grips the handle, the moment between the center of mass of each of the components is small, so that the user's hand can more conveniently manipulate the hand-held vacuum cleaner during use, allowing the user to operate. Convenient and comfortable.

However, in actual use, it is found that the power supply of the hand-held vacuum cleaner of the above structure is relatively Sufficient, after a period of use, it needs to be charged, which brings inconvenience to the user. This may be because the space under the handle is very limited and the installed power supply is small.

Therefore, it is obviously practical and practical to develop a hand-held vacuum cleaner with sufficient power supply and convenient operation while at the same time taking into consideration the beautiful appearance.

Summary of the invention

It is an object of the invention to provide a hand-held vacuum cleaner.

In order to achieve the above object, the technical solution adopted by the present invention is: a hand-held vacuum cleaner comprising a suction pipe, a main body, a handle and a power source, wherein the main body is provided with an air flow generator and a separating device; the handle has a first end a second end and a longitudinal axis; the power source is located between the body and the handle, and the power source is located forward of the handle.

In the above, both the air flow generator and the separating device can adopt the existing structure.

A flow generator is used to generate a flow of gas along the suction conduit; a separation device is in communication with the suction conduit to separate dirt and dust from the flow; and a power source is used to supply power to the flow generator.

In the above technical solution, the power source is disposed in the power box, and the side of the power box body is opposite to the main body.

Preferably, the power box body and the main body are integrated.

In the above technical solution, the power box body has a rectangular shape, and at least two battery assemblies arranged vertically are disposed therein.

In the above technical solution, the power box body has an L shape, and an L-shaped distributed battery assembly is disposed therein; and a bottom side of the power box body is connected to the second end of the handle.

In the above technical solution, a power cover is disposed at a bottom of the power box body. After the power cover is opened, it can be installed or removed from the power supply. There is a detachable connection structure between the power box body and the power cover. In the utility model, the power source can be taken out and charged, and can also be directly charged on the vacuum cleaner interface. These methods are all prior art.

In the above technical solution, the airflow generator is disposed adjacent to the first end of the handle, and the longitudinal axis of the handle passes through at least a portion of the airflow generator.

In the above technical solution, the separating device is located between the suction duct and the handle.

In the above technical solution, the outer surface of the handle is provided with a holding structure. For example, a sand rubber piece is arranged on the outer surface of the handle. Make it ergonomic and easy to hold.

In the above technical solution, the angle between the suction duct and the longitudinal axis of the handle is 60 to 78 degrees.

Due to the application of the above technical solutions, the utility model has the following advantages compared with the prior art:

1. The utility model is designed with a new vacuum cleaner structure, the power source is arranged between the main body and the handle, and the power source is located in front of the handle. Since the power source is the heaviest mechanism in the entire hand-held vacuum cleaner, the structure can be hand-held. The center of gravity of the vacuum cleaner is biased toward the bottom of the battery, so that the center of gravity of the cleaner is very close to the front position of the handle, thereby facilitating the user's operation and making the user's operation more comfortable;

2. The power supply of the utility model is disposed between the main body and the handle. Since the position has a large space, more battery components can be installed, so that the vacuum cleaner has a stronger power output capability and meets the user's long-term use. demand;

3. The utility model is provided with a power cover at the bottom of the power box body, and the battery component inside can be taken out for charging, repairing or replacing, thereby greatly facilitating the operation;
