Description

Technical Field

[0001] This utility model belongs to the field of dust removal technology, specifically providing a base station for a vacuum cleaner. Background Technology

[0002] With the rapid development of smart home technology, vacuum cleaners have evolved from traditional manual operation devices to automation and intelligence. Among them, vacuum cleaner base stations with automatic dust collection functions have become one of the mainstream products on the market because they can significantly reduce the frequency of users manually emptying the dust bag. The core function of these base stations is to hold the dust bag through an internal dust collection chamber. When the vacuum cleaner returns to the base station after completing its cleaning task, the base station can automatically suck in the dust, debris, and other foreign objects collected in the vacuum cleaner's dust box and store them in the dust bag, achieving a convenient "no-manual dust emptying" experience and greatly improving the convenience for users.

[0003] To ensure hygiene and prevent the accumulation of foreign objects in the dust collection chamber, which can breed bacteria, mold, and other microorganisms, some existing vacuum cleaner base stations are equipped with additional disinfection devices. These devices disinfect the internal environment of the dust collection chamber, reducing the risk of odors and indoor air pollution during the storage of foreign objects. However, since dust bags are usually made of flexible materials (such as non-woven fabric or paper), they are prone to deformation and displacement under airflow during dust collection operations at the base station, causing their surface to adhere directly to the disinfection device.

[0004] This adhesion issue can cause multiple hidden dangers: Firstly, if the disinfection device is an ultraviolet disinfection lamp, the dust bag will block the path of ultraviolet radiation after being attached. This not only prevents the disinfection light from covering the key areas of the dust collection chamber, resulting in incomplete disinfection, but may also lead to localized overheating, aging, or even combustion risks due to the dust bag absorbing ultraviolet energy for a long time. Secondly, if the disinfection device is an ozone generator or other component that requires air circulation to function, the dust bag will block the air outlet or inlet of the disinfection device, significantly reducing disinfection efficiency. At the same time, the long-term contact between the flexible dust bag and the surface of the disinfection device may also cause the dust bag to break due to slight temperature changes or material interactions during the operation of the disinfection device, resulting in the leakage of foreign objects and affecting the normal use of the base station. Utility Model Content

[0005] One objective of this invention is to solve the problem that dust bags easily adhere to the surface of the disinfection device, thus affecting its operation.

[0006] To achieve the above objectives, this utility model provides a base station for a vacuum cleaner, characterized in that it comprises:

[0007] The main body has an internally defined dust collection chamber for accommodating a dust bag, which is used to store foreign objects discharged from the vacuum cleaner.

[0008] Disinfection device for disinfecting the dust collection chamber;

[0009] A protective device is provided around the disinfection device to prevent the dust bag from adhering to the disinfection device.

[0010] Optionally, the disinfection device is a plasma generator, which has a main body and a plasma emitting head disposed on the main body.

[0011] Optionally, the protective device includes a mounting plate and a grid located on one side of the mounting plate, the grid being configured to surround the plasma emitter.

[0012] Optionally, the plasma generator is disposed at the top of the dust collection chamber, and the main body of the plasma generator is disposed on the side of the mounting plate away from the grid. The mounting plate is provided with through holes so that the plasma emitting head can extend into the grid through the through holes.

[0013] Optionally, the body further defines a dust collection channel extending in the vertical direction, the dust collection channel connecting the dust collection chamber and the outside of the base station, and the plasma generator is disposed on one side of the dust collection channel in the horizontal direction.

[0014] Optionally, the horizontal distance between the plasma generator and the dust collection channel is selected from any value between 150 mm and 300 mm.

[0015] Optionally, the plasma emitter is positioned downwards, the grid is arranged horizontally around the plasma emitter, and the bottom end of the grid is lower than the plasma emitter in the vertical direction.

[0016] Optionally, the body further defines a receiving cavity for accommodating the plasma generator and a communication port connecting the receiving cavity and the dust collection cavity, wherein the plasma emitting head and the grid extend into the dust collection cavity through the communication port.

[0017] Optionally, the mounting plate of the protective device is engaged with the edge of the communication port near the receiving cavity;

[0018] The base station is also provided with a pressure plate to clamp and fix the main body of the plasma generator between the pressure plate and the mounting plate. The two ends of the pressure plate along its length are respectively provided with fixing holes to fix the pressure plate to the main body of the base station by fasteners.

[0019] Optionally, the body is also provided with a front cover to open or close the dust collection chamber.

[0020] Optionally, a seal is provided between the mounting plate and the bottom wall of the receiving cavity.

[0021] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, by setting up a protective device around the disinfection device, the dust bag is prevented from adhering to the disinfection device, thereby avoiding the dust bag from affecting the normal operation of the disinfection device.

[0022] Furthermore, by surrounding the plasma emitter with a grid, the dust bag and the plasma emitter can be physically isolated, preventing the dust bag from directly contacting the plasma emitter and avoiding localized overheating and combustion of the dust bag.

[0023] Furthermore, by setting the horizontal distance between the plasma generator and the dust collection channel between 150mm and 300mm, it is possible to avoid foreign objects (such as large particles of debris) from hitting the emission head during transport, and to ensure that the plasma concentration is sufficient when it reaches the vicinity of the channel.

[0024] Furthermore, by setting the plasma emitter head downwards, further setting the grid around the plasma emitter head in the horizontal direction, and making the bottom end of the grid lower than the plasma emitter head in the vertical direction, the dust bag is prevented from attaching to the plasma emitter head from the horizontal direction and from below.

[0025] Furthermore, by defining a cavity for accommodating the plasma generator and a connecting port between the cavity and the dust collection cavity within the main body, the plasma emitter and the grid extend into the dust collection cavity through the connecting port, thereby providing a closed protective space for the plasma generator and preventing dust and moisture from entering the dust collection cavity and damaging the internal circuitry.

[0042] Those skilled in the art should understand that the embodiments described below are merely some embodiments of the present invention, and not all embodiments of the present invention. These embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0043] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "top," "bottom," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. For example, unless otherwise specified, the terms "installation," "connection," "joining," and "fixing" can specifically refer to any feasible connection form such as bolt connection, screw connection, welding, insertion, riveting, fusion welding, or snap-fit.

[0045] With the rapid development of the cleaning technology field and the improvement of people's living standards, small household cleaning products such as vacuum cleaners are also developing towards intelligence, user-friendliness, and maintenance-free operation. The advantages of base stations are particularly prominent. After normal use, users can simply place the vacuum cleaner on the base station, and the dust in the vacuum cleaner will be directly sucked into the base station. The base station only needs to be cleaned every two to three months, achieving long-term maintenance-free operation for users. However, if the dust collection chamber inside the base station is not cleaned for a long time, bacteria will grow, affecting the user's health.

[0046] like Figures 1 to 4 As shown, in some embodiments of this utility model, the base station 001 for the vacuum cleaner 002 includes a body 100, a disinfection device 200, and a protective device 300. The body 100 internally defines a dust collection chamber 110 for accommodating a dust bag (not shown in the figure). The dust collection chamber 110 provides a fixed installation space for the dust bag, preventing it from shifting inside the base station 001 and ensuring a stable foreign object collection path.

[0047] The dust bag centrally stores foreign objects discharged from the vacuum cleaner 002, and only the dust bag needs to be replaced during subsequent cleaning, improving maintenance convenience. The disinfection device 200 is used to disinfect the dust collection chamber 110, and the protective device 300 is set around the disinfection device 200 to prevent the dust bag from adhering to the disinfection device 200.

[0048] For example, the disinfection device can be an ultraviolet disinfection lamp. If the dust bag is attached to the ultraviolet disinfection lamp, it will block the path of ultraviolet irradiation. This will not only prevent the disinfection light from covering the key area of ​​the dust collection chamber 110, resulting in incomplete disinfection, but may also cause local overheating, aging, or even combustion risks due to the dust bag absorbing ultraviolet energy for a long time.

[0049] For example, a disinfection device can also be an ozone generator. If the dust bag is attached to the ozone generator, it may block the air outlet or air inlet of the disinfection device, greatly reducing the disinfection efficiency. At the same time, the flexible dust bag may be damaged due to slight temperature changes or material interactions during the operation of the disinfection device, resulting in the leakage of foreign objects.

[0050] Those skilled in the art will understand that, by providing a protective device 300 around the disinfection device, this embodiment can separate the dust bag from the disinfection device, preventing the dust bag from contacting the surface of the disinfection device.

[0051] like Figures 4 to 5 As shown, in some embodiments of this utility model, the disinfection device 200 is a plasma generator 210, which has a main body 211 and a plasma emitting head 212 disposed on the main body 211.

[0052] like Figures 5 to 6 As shown, in some embodiments of this utility model, the protective device 300 includes a mounting plate 310 and a grid 320 located on one side of the mounting plate 310. The grid 320 is configured to surround the plasma emitter 212, which can physically isolate the dust bag from the plasma emitter 212, prevent the dust bag from directly contacting the plasma emitter 212, and avoid local overheating and combustion of the dust bag. The mounting plate 310 provides a fixed foundation for the grid 320 and also serves as a mounting carrier for the main body 211 of the plasma generator 210, ensuring the relative position stability of the protective device 300 and the disinfection device 200.

[0053] like Figures 4 to 6 As shown, the plasma emitter 212 has two parts: one emits a high-voltage positive charge, and the other emits a high-voltage negative charge. The plasma emitter 212 ionizes the air (mainly oxygen) using the positive and negative high-voltage charges to generate a large number of positive and negative ions. The instantaneous neutralization of positive and negative charges in the air by these ions releases energy, destroying the bacterial surface membranes distributed in the dust collection chamber 110, thereby causing the bacteria in the dust collection chamber 110 to die, achieving a sterilization and disinfection effect. The raw material for ionizing the air is oxygen from the environment, eliminating the need for additional disinfection consumables and reducing user costs.

[0054] In addition, the grid 320 has a mesh structure, which not only prevents dust bags and foreign objects from coming into contact with the disinfection device 200, but also does not block the diffusion of ultraviolet rays, ozone or plasma, ensuring that the disinfection effect is not weakened.

[0055] Continue reading Figure 4 In some embodiments of this utility model, the plasma generator 210 is disposed at the top of the dust collection chamber 110, and its main body 211 is disposed on the side of the mounting plate 310 away from the grid 320, which can prevent the main body 211 from contacting the dust in the dust collection chamber 110 and extend the life of the main body 211. The mounting plate 310 is provided with a through hole 311 so that the plasma emission head 212 can extend into the grid 320 through the through hole 311.

[0056] like Figures 1 to 4 As shown, in some embodiments of this utility model, the main body 100 further defines a dust collection channel 120 extending in the vertical direction. The dust collection channel 120 connects the dust collection chamber 110 and the outside of the base station 001. The plasma generator 210 is disposed on one side of the dust collection channel 120 in the horizontal direction. The user can place the vacuum cleaner 002 on the base station 001. At this time, foreign objects in the vacuum cleaner 002 are transported through the dust collection channel 120 of the base station 001 to the dust bag in the dust collection chamber 110, so as to achieve the purpose of cleaning the vacuum cleaner 002.

[0057] The dust bag is installed in the dust collection chamber 110 and is connected to the dust collection channel 120 so that foreign objects can directly enter the dust bag after passing through the dust collection channel 120.

[0058] In some embodiments of this invention, the horizontal distance between the plasma generator 210 and the dust collection channel 120 is selected from any value between 150mm and 300mm. A distance of 150-300mm avoids foreign objects (such as large particles of debris) from hitting the emission head during transport, and also ensures that the plasma concentration is sufficient when it reaches the vicinity of the channel.

[0059] like Figures 4 to 5 As shown, in some embodiments of this utility model, the plasma emitter 212 is arranged facing downwards, and the grid 320 is arranged horizontally around the plasma emitter 212, with the bottom end of the grid 320 being lower than the plasma emitter 212 in the vertical direction. The horizontal surrounding of the grid 320 can prevent the dust bag from attaching horizontally, and the bottom end being lower than the emitter head can prevent the dust bag from contacting it from below.

[0060] like Figure 7As shown, in some embodiments of this utility model, the main body 100 further defines a receiving cavity 130 for accommodating the plasma generator 210 and a connecting port 140 connecting the receiving cavity 130 and the dust collection cavity 110. The plasma emission head 212 and the grid 320 extend into the dust collection cavity 110 through the connecting port 140. The receiving cavity 130 provides a closed protective space for the plasma generator 210, preventing dust and moisture in the dust collection cavity 110 from intruding, damaging the internal circuitry, or affecting the ionization effect.

[0061] Continue reading Figure 7 In some embodiments of this utility model, the mounting plate 310 of the protective device 300 is snapped onto the edge of the communication port 140 near the receiving cavity 130; the base station 001 is also provided with a pressure plate 400 to clamp and fix the main body 211 of the plasma generator 210 between the pressure plate 400 and the mounting plate 310. Fixing holes 410 are respectively provided at both ends of the length direction of the pressure plate 400 to fix the pressure plate 400 to the main body 211 of the base station 001 by means of fasteners.

[0062] Those skilled in the art will understand that the clamping and fixing can prevent the plasma generator 210 body 211 from shifting due to the vibration of the base station 001, ensuring the stability of the transmitter head position and the disinfection range does not shift; the fixing hole 410, together with the fixing parts (such as screws), realizes the detachable fixing of the pressure plate 400. If the plasma generator 210 needs to be repaired in the future, only the fixing parts need to be removed to remove the pressure plate 400, which improves the convenience of maintenance; the clamping force between the pressure plate 400 and the mounting plate 310 can enhance the fit of the sealing part 500, allowing the sealing part 500 to fill the gap between the mounting plate 310 and the receiving cavity 130 more tightly, thereby improving the sealing effect.

[0063] like Figures 1 to 4 As shown, in some embodiments of this utility model, the main body 100 is also provided with a front cover 150 to open or close the dust collection chamber 110. When closed, the dust collection chamber 110 is sealed to prevent internal bacteria and dust from leaking to the outside of the base station 001, thus avoiding pollution of the indoor environment, and at the same time preventing external impurities from entering the dust collection chamber 110 and interfering with the disinfection effect; when opened, it is convenient to replace the dust bag, clean the inner wall of the dust collection chamber 110, or maintain the disinfection device 200.

[0064] like Figures 5 to 7 As shown, in some embodiments of this utility model, a sealing element 500 is provided between the mounting plate 310 and the bottom wall of the receiving cavity 130, which can block dust and moisture in the dust collection cavity 110 from entering the receiving cavity 130 through the gap between the mounting plate 310 and the receiving cavity 130, thereby avoiding contamination of the main body 211 of the plasma generator 210 (such as circuits and ionization components), preventing the main body 211 from malfunctioning or the ionization efficiency from decreasing, and extending the service life of the disinfection device 200.

[0065] like Figure 4As shown, base station 001 includes a motor assembly 600, a filter 700, and a power cord. The filter 700 is located on the lower side of the dust collection chamber 110, and the motor assembly 600 is located on the lower side of the filter 700. The motor assembly 600 includes a fan that exhausts air downwards to create a negative pressure in the dust collection chamber 110, thereby causing foreign objects in the dust cup to be sucked into the dust bag in the dust collection chamber 110 through the dust collection channel 120.

[0066] like Figures 1 to 2 As shown, the base station 001 is equipped with an upper connector 160, which can be connected to the dust cup of the vacuum cleaner 002, so that foreign objects in the dust cup can be discharged into the dust bag in the dust collection chamber 110 through the dust collection channel 120.

[0067] The working process of base station 001 is as follows:

[0068] After using the vacuum cleaner 002, the user places it in the designated location on the base station 001. Dust, debris, and other foreign objects stored inside the vacuum cleaner 002 are then directionally transported to the dust collection chamber 110 through the dust collection channel 120 extending vertically along the base station 001 body 100, under the combined action of its own exhaust power and gravity. A dust bag is pre-installed in the dust collection chamber 110, providing a fixed installation space for the dust bag and preventing it from shifting, ensuring that foreign objects transported from the dust collection channel 120 fall stably into the dust bag. The dust bag centrally collects the foreign objects, eliminating the need for the user to manually clean the vacuum cleaner 002 or disassemble the base station 001; the dust bag only needs to be replaced every two to three months.

[0069] Furthermore, the base station 001 disinfects the dust collection chamber 110, where foreign objects are concentrated and bacteria are prone to grow, through the disinfection device 200. The protective device 300 physically isolates the dust bag from the disinfection device 200 in advance to prevent the dust bag from sticking and causing disinfection failure. At the same time, the grid structure of the grid 320 does not block the diffusion of the disinfection medium. The plasma generator 210 body 211 is placed in the receiving cavity 130 defined by the body 100. Its plasma emission head 212 extends into the dust collection chamber 110 through the connecting port 140 and enters the area surrounded by the grid 320 through the through hole 311 of the mounting plate 310.

[0070] Furthermore, the two plasma emitters 212 emit high-voltage positive and high-voltage negative charges respectively, which can ionize oxygen in the air to generate a large number of positive and negative ions. These ions diffuse in the dust collection chamber 110, and the positive and negative ions release energy instantly upon neutralization in the air, directly destroying the bacterial cell membrane, causing the bacteria in the dust collection chamber 110 to die, and there is no need to add additional disinfection consumables (using oxygen as raw material), reducing the cost of use.

[0071] The technical solution of this utility model has been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments. Without departing from the technical principles of this utility model, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features.
