Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaner accessories, in particular to a handheld cleaning brush head for a vacuum cleaner. Background Art

[0002] Using a vacuum cleaner for cleaning is an indispensable part of modern home life, greatly reducing the heavy burden of manual cleaning. With its efficient dust collection ability and diverse accessory design, vacuum cleaners can easily meet various cleaning needs. These carefully designed accessories can not only perform deep cleaning on surfaces of different materials such as carpets and sofa fabrics, but also effectively remove difficult-to-handle debris such as pet hair.

[0003] For example, the patent application number CN115721199A, with the invention name "Vacuum cleaner attachment and vacuum cleaner", discloses a vacuum cleaner attachment, including: a housing and an air duct, the air duct is located inside the housing, the air duct is used to connect to a vacuum source, a combing pin plate is connected to the housing, and a plurality of combing pins are arranged on the combing pin plate. In the combing mode, the pusher moves until the combing pins are exposed through the through slots; in the cleaning mode, the pusher moves until the pusher plate covers the outer ends of the combing pins, thereby achieving combing and vacuuming operations on the blanket.

[0004] For example, the patent with authorization announcement number CN219742587U and invention name “Vacuum Cleaner Accessory” discloses that the accessory includes a main body connected to the vacuum cleaner, and the vacuum cleaner accessory also includes a brush head assembly detachably connected to the main body; the brush head assembly includes a mounting shell detachably connected to the main body, a row of brushes arranged on the mounting shell, and a suction port piece movably connected to the mounting shell; the row of brushes includes brush teeth arranged side by side, the suction port piece can be passively moved to the bottom of the brush teeth, and the suction port piece moves in close contact with the brush teeth.

[0005] However, these accessories can only perform basic dust removal. When deep cleaning carpets and fabrics, we often encounter stubborn stains. In order to completely remove these stains, wet cleaning has become an indispensable cleaning method.

[0006] As a leader in wet cleaning equipment, the steam cleaner's unique working principle makes the cleaning process more efficient and convenient. The steam cleaner is equipped with a clean water tank and a sewage tank. It wets the fabric surface through an external brush head and uses the scrubbing function to deeply clean stains. Subsequently, the vacuum fan quickly sucks the generated sewage into the sewage tank of the main unit to ensure a smooth and efficient cleaning process. However, steam cleaners are usually used for sterilization and disinfection, which is different from daily dust removal operations. Therefore, replacing different equipment in different usage scenarios is not only expensive, but also inconvenient to operate and not conducive to home storage. Utility Model Content

[0069] like Figure 1 As shown, the handheld wet cleaning brush head assembly for a vacuum cleaner comprises a housing 1 and a sewage tank 2, a clean water tank 3 and a brush head 4 arranged on the housing 1.

[0070] like Figure 4 , 5 As shown, the brush head 4 is arranged at the front side of the housing 1, and the end surface of the brush head 4 is provided with an air inlet 41, a water spray hole 42 and bristles 43. A water delivery channel and a water pump 5 from the clean water tank 3 to the water spray hole 42 are arranged in the housing 1.

[0071] like Figure 1-5 As shown, a hand-held tube 6 is provided at the rear side of the housing 1, and the hand-held tube 6 includes a hand-held portion 61 at the front side and an interface portion 62 at the rear side. The hand-held tube 6 is provided with an air suction channel s that passes through the hand-held portion 61 and the interface portion 62, and the interface portion 62 is used to connect a vacuum cleaner, and this connection method can be through a flexible tube 300 such as a wave telescopic tube.

[0072] like Figure 1 , 3 As shown in FIGS. 5 and 6, the handheld part 61 is provided with a control part 7 for controlling the water pump 5 to pump water from the clean water tank 3 to discharge water from the water spray hole 42, and the sewage tank 2 is provided with a gas-liquid inlet connected to the air inlet 41 and an air flow outlet b connected to the air suction channel s. When the vacuum cleaner is in operation, the gas-liquid mixture enters the sewage tank 2 from the air inlet 41 through the gas-liquid inlet and separates, the liquid accumulates in the sewage tank 2, the gas flows out from the air flow outlet b, and enters the vacuum cleaner through the air suction channel s of the handheld tube 6.

[0073] like Figure 5 As shown, the control member 7 includes an exposed operating portion 71, a curved portion 72 protruding upward is provided on the front side of the operating portion 71, and an action portion 73 is provided on the front side of the curved portion 72. The housing 1 is provided with a vertical wall, and a switch portion 50 for controlling the operation of the water pump 5 is provided on the front side of the vertical wall. The curved portion 72 is embedded and placed on the top of the vertical wall, and the control member 7 rotates with the contact point between the vertical wall and the curved portion 72 as a fulcrum. The action portion 73 is engaged and disengaged with the switch portion 50 to realize the opening and closing of the water pump 5.

[0074] Compared with traditional vacuum cleaner accessories, the biggest highlight of this handheld wet cleaning vacuum cleaner brush head 4 is that it can be docked with an ordinary vacuum cleaner host to achieve a wet and dual-use functional design. Users can easily switch cleaning modes according to different cleaning needs. In daily cleaning, you can use the dry cleaning mode to quickly remove dust and particulate matter. When you encounter stains that require deep cleaning, by pressing the control part 7, draw clean water or detergent from the clean water tank 3 and spray it on the surface of the stain, which can easily dissolve the stain, and can separate the sewage generated during the cleaning process from the surface of the cleaning object by sucking it away through the suction of the vacuum cleaner. This flexible switching design not only improves the cleaning efficiency, but also brings great convenience to users.

[0075] like Figure 5 As shown, a filter 64 is also provided at the junction of the interface portion 62 and the hand-held portion 61 to prevent water or large impurities from entering the vacuum cleaner main body.

[0076] like Figure 1 , 3 As shown, in this embodiment, the clean water tank 3 is flat and is laterally arranged at the lower side of the hand-held tube 6. A holding space p is provided between the clean water tank 3 and the hand-held tube 6, and the control member 7 is located in the holding space p.

[0077] This design makes the entire brush head assembly compact while having a more reasonable center of gravity design, making it easier for users to operate the brush head assembly, while also providing a larger clean water storage space. Without affecting the comfort of holding, it can hold more clean water, extend the time of a single cleaning operation, and improve cleaning efficiency.

[0078] like Figure 5 , 6As shown, the front side wall of the clean water tank 3 is provided with a first plug-in column 31 and a second plug-in column 32, the first plug-in column 31 is lower than the second plug-in column 32, and the second plug-in column 32 is connected to the water delivery channel. A water pipe 33 is provided in the clean water tank 3, and the two ends of the water pipe 33 are respectively connected to the first plug-in column 31 and the second plug-in column 32. There is a water inlet gap between the water pipe 33 and the first plug-in column 31. In this embodiment, the outer peripheral wall of the first plug-in column 31 includes a longitudinal plane section and an arc surface, that is, the cross section of the first plug-in column 31 is an incomplete circle. The cross section of the inner hole of the water pipe 33 is circular, so there is a gap between the inner wall of the water pipe 33 and the longitudinal plane section to form a water inlet gap. After the water in the clean water tank 3 enters the water pipe 33 from the water inlet gap, it is output from the inner hole of the second plug-in column 32 and enters the internal water delivery channel.

[0079] The arrangement of the first plug-in column 31 and the second plug-in column 32 not only ensures a stable connection with the water pipe 33, but also optimizes the water inlet process through different height layouts. In particular, the first plug-in column 31 is located at a lower position of the clean water tank 3, and this design makes the water inlet position closer to the bottom of the water tank. When the brush head assembly is lifted to start cleaning, even if the water level in the clean water tank 3 drops, since the water inlet position is at a low position, it can still ensure effective water absorption, thereby maximizing the use of water resources in the clean water tank 3.

[0080] like Figure 5 , 6 As shown, the sewage tank 2 includes a tank body 21 and a gas-liquid separation cover 22 that can be detached from the tank body 21. After the gas-liquid mixture enters the sewage tank 2, the liquid is retained in the tank body 21, and the gas flows out from the airflow outlet b between the gas-liquid separation cover 22 and the tank body 21.

[0081] like Figure 5 As shown, the sewage tank 2 and the clean water tank 3 are partially transparent, and the upper side of the clean water tank 3 is provided with a water inlet H blocked by a sealing plug 34. The partially transparent design allows the operator to observe the water level or state of the sewage.

[0082] like Figure 2-4 As shown, the sewage tank 2 is vertically arranged between the brush head 4 and the clean water tank 3, and the brush head 4 is inclined upward from front to back. The rest of the housing 1 except the brush head 4 has a common lower surface F. The end surface of the brush head 4 and the common lower surface F are located at the same height.

[0083] Firstly, the vertical arrangement of the sewage tank 2 effectively balances the weight distribution between the brush head 4 and the clean water tank 3, making the entire vacuum cleaner brush head 4 more stable during operation.

[0084] Secondly, the rest of the housing 1 except the brush head 4 has a common lower surface F. This design enables the entire vacuum cleaner brush head 4 to lie flat against the object to be cleaned during operation. This flat bottom surface not only provides a stable support force, but also makes it easier for the user to push the vacuum cleaner. Whether cleaning the floor, carpet or other flat surface, the user only needs to push the vacuum cleaner brush head 4 lightly, and it can move forward easily, greatly saving manpower.

[0085] Finally, the end surface of the brush head 4 and the common lower surface F are at the same height, which further enhances the stability and convenience of the vacuum cleaner brush head 4. This design allows the brush head 4 to always remain parallel to the ground during the cleaning process, avoiding the inconvenience of operation and poor cleaning effect caused by the height difference. At the same time, it also allows the user to feel a more uniform support force when pushing, so that the cleaning task can be completed more easily.

[0086] As shown in the figure, the bottom of the front end of the brush head 4 housing 1 has a groove y with an arc-shaped cross-section, and the air inlet 41 is formed in the groove y, so as to avoid the air inlet 41 being blocked by the surface of the cleaning object during operation, affecting the dust and water absorption effect.

[0087] like Figure 5 , 6 As shown, in the design of the brush head 4 of the handheld wet cleaning vacuum cleaner, the detachability of the sewage tank 2 is cleverly optimized. Specifically, a plug-in portion E is specially designed on the shell 1, and the plug-in portion E encloses and forms a slot C with an upper opening. The plug-in portion E is provided with a gas-liquid interface j that is connected to the gas-liquid inlet, and an airflow interface g that is connected to the airflow outlet b. The gas-liquid interface j is connected to the air inlet 41 through the air cavity of the brush head 4. The airflow interface g is connected to the air suction channel s of the handheld tube 6. The design of this slot allows the sewage tank 2 to be easily and reliably plugged into it, which brings many beneficial effects to the cleaning operation.

[0088] First, the detachable design of the sewage tank 2 makes cleaning and maintenance extremely convenient. When the sewage tank 2 is full, the user does not need to take the trouble to disassemble the entire vacuum cleaner brush head 4. The user only needs to pull out the sewage tank 2, pour out the sewage and clean it, and then reinsert it. This design not only saves the user's time, but also improves cleaning efficiency.

[0089] Secondly, the upper opening design of the slot C ensures the stability and safety of the sewage tank 2 during the plugging process. When inserting the sewage tank 2, the user only needs to align the upper part of the box body with the opening of the slot, and then gently press down, and the sewage tank 2 can be firmly fixed in the slot. This design avoids the misalignment or tilting that may occur during the plugging process, and ensures the tight connection between the sewage tank 2 and the vacuum cleaner brush head 4.

[0090] Furthermore, the detachable sewage tank 2 design also enhances the flexibility and adaptability of the vacuum cleaner brush head 4. Users can choose sewage tanks 2 of different capacities for replacement according to different cleaning needs. For example, when cleaning a large area, a sewage tank 2 with a larger capacity can be selected to reduce the number of replacements; and when cleaning a small area or a local area, a sewage tank 2 with a smaller capacity can be selected to reduce the overall weight.

[0091] like Figure 5 , 6 As shown, the brush head 4 includes a lower brush head shell 401 and an upper brush head shell 402 which are detachable from each other. An air cavity is formed between the lower brush head shell 401 and the upper brush head shell 402, and the upper brush head shell 402 is transparent.

[0092] First, when the brush head 4 needs to be cleaned or parts need to be replaced, the user can easily separate the lower brush head shell 401 and the upper brush head shell 402, thereby conveniently performing cleaning and maintenance and avoiding clogging of the inner cavity of the brush head 4.

[0093] The upper brush head shell 402 is made of a transparent material, and this design allows the user to intuitively see the working status of the brush head 4. For example, the user can clearly see the cleaning effect of the brush head 4 and whether there is any debris blocking it. This transparent design not only enhances the user's confidence in use, but also makes the cleaning process more transparent, so that the user can grasp the cleaning progress at any time.

[0094] The air inlet 41 is located at the front end of the lower brush head shell 401. The air inlet 41 is in a transverse strip shape and is provided with a plurality of mutually spaced baffle walls that divide it into a plurality of units. The front end of the lower brush head shell 401 has a groove y with an arc-shaped cross section, and the air inlet 41 is formed in the groove y.

[0095] This design allows the air inlet 41 to maintain a sufficiently large area to ensure sufficient airflow, while effectively preventing debris and dust from entering the brush head 4. The design of the baffle wall divides the air inlet 41 into multiple units, each of which can independently inhale air, thereby improving the uniformity and stability of air inhalation. In addition, the baffle wall can also play a filtering role, blocking larger debris and dust outside the air inlet 41, further protecting the motor and other sensitive components inside the brush head 4.

[0096] like Figure 4As shown, the bristles 43 are arranged in a row on the rear side of the air inlet 41, and the bristles 43 are inclined forward from top to bottom. The water spray hole 42 is located on the rear side of the bristles 43. The design of the bristles 43 being inclined forward from top to bottom may help guide the water flow and the bristles 43 in the same direction, thereby enhancing the cleaning effect. When the water flow is sprayed out from the water spray hole 42, it may flow in the direction of the bristles 43, thereby more effectively flushing and cleaning the target surface. When the water is sprayed out from the water spray hole 42, it will carry a certain kinetic energy and impact force. This kinetic energy and impact force can help the bristles 43 to more effectively remove dirt and impurities on the target surface. The synergistic effect of the bristles 43 and the water spray hole 42 may produce a better cleaning effect. The bristles 43 can physically scrape off the dirt, while the water flow can flush away the dirt scraped off by the bristles 43, while helping the bristles 43 to better clean the target surface.

[0097] The above is a detailed introduction to the handheld wet cleaning brush head assembly for a vacuum cleaner provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the present invention and its core ideas. It should be pointed out that for ordinary technicians in this technical field, the present invention can also be improved and modified in a number of ways without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
