Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner base technology, and in particular to a smart vacuum cleaner base. Background Technology

[0002] A vacuum cleaner base station is a device used to store, clean, and charge a vacuum cleaner. It typically consists of a base station body, a support rod, and a base assembled from top to bottom. The base station body is the main structure that enables the functions, and its internal components are designed accordingly. For structural stability, the motor that drives the fan is usually placed on the base. The reason for this is that the AC motors used are generally large and heavy. Placing them in the base station body would pose a risk of the entire base station tipping over. However, this design inevitably means that the motor is far from the dust collection chamber in the base station body, requiring the technical requirements of airflow through duct design. This inevitably makes the structure bulky and reduces working efficiency.

[0003] Referring to Chinese Patent Application No. 202222193980.4, entitled "A Vacuum Cleaner Base Station", the invention includes a main body with a dust collection chamber, in which a dust bag is installed; the dust collection chamber is also provided with an air inlet and an air outlet, and the dust bag is in fluid communication with the air inlet; the air outlet is also provided with a cover plate, and the cover plate is provided with a plurality of first exhaust holes in fluid communication with the air outlet; the cover plate is also provided with a plurality of support members, which are spaced apart to support at least a portion of the bottom of the dust bag, so that the bottom of the dust bag is away from at least a portion of the first exhaust holes.

[0004] The aforementioned patent also uses the method of setting the motor on the base and designing an additional air duct to solve the problem of the base station tilting, but this also makes the overall structure bulky. Utility Model Content

[0005] In view of the above-mentioned problems in the prior art, a smart vacuum cleaner base is provided. The DC motor has a smaller volume than the AC motor, which can avoid the risk of the base body tipping over. Moreover, the motor does not need to be placed in the base, which can effectively shorten the length of the gas flow channel between the fan and the dust collection chamber, making the internal structure design simpler and more reliable, thereby overcoming at least one of the above-mentioned technical defects.

[0006] The specific technical solution is as follows:

[0007] A smart vacuum cleaner base includes a base body, a support rod, and a base connected sequentially from top to bottom. The base body has a receiving cavity for storing the vacuum cleaner from top to bottom. The bottom of the receiving cavity also has a dust collection cavity. A dust bag can be detachably placed in the dust collection cavity. In the working state, the dust can of the vacuum cleaner is opened and at least partially inserted into the dust collection cavity.

[0008] The base body is equipped with a control circuit board and a DC motor electrically connected to the control circuit board. The output shaft of the DC motor is fitted with a fan blade to form a fan, which is used to create a negative pressure in the dust collection chamber, so that the dust and garbage in the dust bin are adsorbed into the dust bag in the dust collection chamber.

[0009] Preferably, the base body has an installation cavity for accommodating the fan located below the dust collection chamber, and there is a gas flow channel between the installation cavity and the dust collection chamber to create negative pressure in the dust collection chamber.

[0010] Preferably, the base body is also equipped with a power module that is electrically connected to the control circuit board, and the power module has a socket for connecting to mains power.

[0011] Preferably, the control circuit board integrates a rectifier and transformer module to convert the AC power supplied by the power module into DC power and adjust it to the operating voltage of the DC motor.

[0012] Preferably, the base body is also equipped with an ultraviolet germicidal lamp that is electrically connected to the control circuit board, and the ultraviolet germicidal lamp is at least partially located in the dust collection chamber for sterilizing the dust and garbage in the dust bag.

[0013] Preferably, the inner wall of the dust collection chamber is recessed to form an annular groove, and the ultraviolet germicidal lamp is in the shape of an annular strip and is embedded in the annular groove.

[0014] Preferably, the base body also has a charging module electrically connected to the control circuit board, and when the vacuum cleaner is stored on the base body, the charging cable of the charging module can be pulled out and electrically connected to the battery pack charging interface of the vacuum cleaner to charge the vacuum cleaner.

[0015] Preferably, the upper or side surface of the base body also has a touch-screen digital display panel electrically connected to the control circuit board to display and control the working status of each component inside the base body.

[0016] The beneficial effects of the above technical solution are as follows:

[0017] The smart vacuum cleaner base includes a base body, a support rod, and a base. The base body contains a receiving cavity, a dust collection cavity, a dust bag, a control circuit board, a DC motor, and a fan blade. It allows the vacuum cleaner to be stored on the base body and collects dust and debris from the vacuum cleaner's dustbin into the dust bag. The use of a DC motor results in a smaller volume compared to an AC motor, avoiding the risk of the base body tipping over. Furthermore, the motor does not need to be housed in the base, effectively shortening the length of the airflow path between the fan and the dust collection cavity, making the internal structure design simpler and more reliable.

[0020] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments are described in detail with reference to the accompanying drawings.

[0021] See Figure 1 and Figure 2 As shown in the figure, the smart vacuum cleaner base provided in this embodiment includes a base body 1, a support rod 2, and a base 3 connected sequentially from top to bottom. The base body 1 has a receiving cavity for storing the vacuum cleaner 11 from top to bottom. The bottom of the receiving cavity also has a dust collection cavity, in which a dust bag can be detachably placed. In the working state, the dustbin of the vacuum cleaner 11 is opened and at least partially inserted into the dust collection cavity; wherein,

[0022] The base body 1 is equipped with a control circuit board 4 and a DC motor 5 electrically connected to the control circuit board 4. The output shaft of the DC motor 5 is fitted with a fan blade to form a fan, which is used to create a negative pressure in the dust collection chamber, so that the dust and garbage in the dust bin are adsorbed into the dust bag in the dust collection chamber.

[0023] Based on the above technical solution, the smart vacuum cleaner base includes a base body 1, a support rod 2, and a base 3. The base body 1 has a receiving cavity, a dust collection cavity, a dust bag, a control circuit board 4, a DC motor 5, and a fan blade. It allows the vacuum cleaner 11 to be stored on the base body 1 and collects the dust and debris in the dust bin of the vacuum cleaner 11 into the dust bag. The DC motor 5 has a smaller volume than the AC motor, which can avoid the risk of the base body 1 tipping over. Moreover, it eliminates the need to place the motor in the base 3, which can effectively shorten the length of the gas flow channel between the fan and the dust collection cavity, making the internal structure design simpler and more reliable.

[0024] In a preferred embodiment, the base body 1 has an installation cavity below the dust collection chamber for accommodating the fan, and a gas flow channel exists between the installation cavity and the dust collection chamber to create negative pressure within the dust collection chamber. Specifically, the dust bag is generally made of paper or fabric, and its material properties allow for visible or invisible gaps, enabling air and wind to pass through while preventing dust and debris from passing through. Therefore, there is no need to design an additional screen structure to block dust and debris, making it more convenient to use. Generally, the dust bag is chosen to have a volume at least three times that of the dust bin, so that it does not need to be replaced daily, and it can be removed upwards through the receiving cavity for replacement. This is a conventional method, so it will not be described in detail here. In addition, the gas flow channel can be formed by gaps reserved during assembly or by setting up ventilation ducts.

[0025] As a further preferred embodiment, a power module 9 electrically connected to the control circuit board 4 is also installed on the base body 1, and the power module 9 has a socket 10 for connecting to mains power. Furthermore, a rectifier transformer module is integrated on the control circuit board 4 to convert the AC power connected to the power module 9 into DC power and adjust it to the operating voltage of the DC motor 5.

[0026] In a preferred embodiment, an ultraviolet germicidal lamp 6 electrically connected to the control circuit board 4 is also embedded in the base body 1, and the ultraviolet germicidal lamp 6 is at least partially located in the dust collection chamber for sterilizing the dust and debris in the dust bag. Furthermore, an annular groove is formed in the inner wall of the dust collection chamber, and the ultraviolet germicidal lamp 6 is annular and embedded in the annular groove.

[0027] As a further preferred embodiment, the base body 1 also has a charging module 7 electrically connected to the control circuit board 4, and when the vacuum cleaner 11 is stored on the base body 1, the charging cable of the charging module 7 can be pulled out and electrically connected to the battery pack charging interface of the vacuum cleaner 11 to charge the vacuum cleaner 11.

[0028] As a further preferred embodiment, the upper or side surface of the base body 1 also has a touch-sensitive digital display panel 8 electrically connected to the control circuit board 4, used to display and control the working status of each component inside the base body 1, including but not limited to whether the DC motor 5 is running, the working status of the ultraviolet germicidal lamp, and the charging status control of the vacuum cleaner 11. However, it is obvious that its control method can also be realized by buttons, and is not limited to this.

[0029] As a further preferred embodiment, the support rod 2 stands upright on the base 3 and its length is adjustable. The base body 1 is installed at the upper end of the support rod 2. Specifically, the support rod 2 can adopt a sleeve structure and achieve an adjustable structure by using a transverse screw as a locking component, or by using a locking sleeve structure, and is not limited to these. In addition, the vacuum cleaner in this embodiment is a handheld vacuum cleaner. The structure for opening its dustbin can be manually operated, or it can be achieved by setting an electromagnet in the dust collection chamber and designing a corresponding magnetic component on the dustbin lid, or by an electrically driven hook structure, or even by causing the dustbin lid to open under the negative pressure provided by the fan. These are all existing common solutions, so they are omitted here. At the same time, the wall of the mounting cavity also has a through hole for gas to flow out to meet the requirements of negative pressure airflow.

[0030] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
