Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a dry and wet vacuum cleaner with a high-efficiency blowing function. Background Technology

[0002] To meet market demand, existing vacuum cleaners on the market offer dual-function blower and vacuum cleaners, generally employing two approaches. One approach involves adding a blower motor and corresponding air ducts and nozzles to an existing vacuum cleaner. While this design integrates blower functionality, it results in a complex, bulky, and costly machine that is also difficult to maintain. The other approach involves modifying the existing vacuum cleaner. To fully utilize the different directional functions of the motor, a dual-purpose air duct design and valves are incorporated, allowing the machine to function as both a vacuum cleaner and, depending on the need, a blower. Examples include a vacuum cleaner described in Chinese Patent No. 201210240737.1, and a vacuum cleaner with a reversing valve structure and blower function described in Chinese Patent No. 202121368086.5.

[0003] The above structural design enables the vacuum cleaner to blow air, but it also has the following drawbacks and limitations: Due to the power limitations of the vacuum motor itself (the power required for vacuuming is often insufficient to meet the power required for blowing air) and the limitations of the air duct structure design, the air velocity at the outlet or exhaust port is very low, making the blowing function practically useless in most usage scenarios. Furthermore, given that wet and dry vacuum cleaners can simultaneously suck in and separate dust, liquids, and other impurities, the above-mentioned air duct structure and reversing valve design are not suitable for wet and dry vacuum cleaners.

[0004] Based on this, it is necessary to invent a dry and wet vacuum cleaner with a high-efficiency blowing function in the existing technology. Utility Model Content

[0005] In order to overcome the technical problems of low blowing efficiency and poor blowing effect of the vacuum cleaners mentioned above, this utility model provides a dry and wet vacuum cleaner with high-efficiency blowing function.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A wet / dry vacuum cleaner with a high-efficiency blowing function, comprising:

[0008] A vacuum cleaner bucket assembly, the vacuum cleaner bucket assembly including a bucket body and a vacuum port disposed on the side wall of the bucket body and communicating with the interior of the bucket body;

[0009] The head assembly includes a float frame, a middle frame, and a motor assembly. The float frame is detachably mounted on the top of the barrel. The middle frame is located above the float frame. The motor assembly is disposed between a lower motor cover and an upper motor cover. The lower motor cover and the upper motor cover are respectively mounted on the float frame and the middle frame.

[0010] The float frame and the middle frame form a sealed first cavity, and the middle frame is provided with a blower facing outward and communicating with the first cavity; the interior of the barrel, the motor assembly, and the first cavity communicate to form an internal blower duct.

[0011] In a preferred embodiment of this utility model, a specific structural design for the head assembly is provided.

[0012] In the technical solution of this embodiment, the motor assembly includes a motor and a fan. The output end of the motor is connected to the fan impeller of the fan to drive the fan impeller to rotate. The air inlet of the fan is connected to the inside of the barrel, and the air outlet of the fan is connected to the first cavity.

[0013] Furthermore, the lower cover of the motor is provided with an air inlet, which is correspondingly provided with the air inlet of the fan, and the air inlet is provided with a grille.

[0014] In a preferred embodiment of this utility model, a specific structural design for a motor assembly is provided.

[0015] In the technical solution of this embodiment, the hair dryer is inclined upward towards the outside of the middle frame, and the hair dryer and the middle frame are an integral structure.

[0016] Furthermore, the blower has an air outlet at one end facing outwards, and a connector is provided at the air outlet. The blower is connected to the vacuum hose assembly through the connector.

[0017] Furthermore, the head assembly also includes sound-absorbing cotton, which is disposed inside the blower tube.

[0018] Furthermore, the head assembly also includes a filter assembly, which is provided inside both the motor assembly and the blower.

[0019] Furthermore, the head assembly also includes a top cover, which is disposed above the middle frame and has a handle and a switch button.

[0020] Furthermore, the vacuum cleaner bucket assembly also includes a buckle, which is rotatably disposed on the side wall of the bucket body. The float frame is provided with a protrusion. When the buckle and the protrusion are engaged, the float frame is fixed above the bucket body.

[0021] Furthermore, the machine head assembly also includes a float, and the float frame is provided with a frame on the side facing the inside of the barrel, with the float disposed in the frame.

[0022] In summary, the wet and dry vacuum cleaner with efficient blowing function provided by this utility model has at least the following technical advantages compared with the prior art:

[0023] 1) When the motor assembly is started, under the suction force of the motor assembly, external air enters the dustbin through the suction port of the dustbin assembly. It then passes through the lower part of the float frame and the motor assembly into the closed first cavity formed between the middle frame and the float frame, where it is pressurized. Finally, the air is discharged at high speed through the upward-sloping blower on the middle frame (or discharged after connecting an external suction hose assembly), achieving a highly efficient blowing effect. This structural design allows external air to be pressurized by the strong suction of the motor assembly and then discharged outwards into the closed cavity between the middle frame and the float frame, significantly increasing the blowing speed of the blower and resulting in high blowing efficiency and excellent blowing effect.

[0024] 2) After external air enters the dust collection bin assembly, the air is filtered multiple times by the filter components inside the dust collection bin assembly and the upper and lower cover grilles of the motor before being blown out from the blower on the middle frame, ensuring the cleanliness of the blown air and improving the user experience.

[0035] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to 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.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0038] See Figure 1 and Figure 2 As shown in the embodiment of this utility model, a wet and dry vacuum cleaner with a high-efficiency blowing function includes a vacuum can assembly 1. The vacuum can assembly 1 includes a can body 11 and a suction port 12 disposed on the side wall of the can body 11 and communicating with the interior of the can body 11. The suction port 12 of the vacuum can assembly 1 communicates with the external environment and the interior of the can body 11. The interior of the can body 11 forms a receiving cavity for accommodating dust and liquids sucked in by the suction port 12 when the vacuuming mode is activated.

[0039] See Figure 1 and Figure 2As shown, the wet / dry vacuum cleaner with high-efficiency blowing function also includes a head assembly. The head assembly includes a float frame 2, a middle frame 3, and a motor assembly 4. The float frame 2 is detachably mounted on the top of the barrel 11, the middle frame 3 is located above the float frame 2, and the motor assembly 4 is located between the lower motor cover 5 and the upper motor cover 6. The lower motor cover 5 and the upper motor cover 6 are respectively mounted on the float frame 2 and the middle frame 3. Specifically, since the float frame 2 and the barrel 11 are detachably connected, the head assembly can be removed from the vacuum barrel assembly 1 as needed, and a vacuum hose assembly or other components can be connected to the head assembly before it is reinstalled on the vacuum barrel assembly 1, making the operation simple. The upper and lower motor covers 6 and 5 are provided on the upper and lower sides of the motor assembly 4. The lower motor cover 5 is mounted on the float frame 2, and the upper motor cover 6 is mounted on the middle frame 3. The two covers are used to fix the motor assembly 4, making the motor assembly 4 the suction-generating structure of the head assembly.

[0040] In this embodiment, a sealed first cavity is formed between the float frame 2 and the middle frame 3. The middle frame 3 is provided with a blower 31 facing outward and communicating with the first cavity. The motor assembly 4 is provided with an air inlet and an air outlet. The air inlet of the motor assembly is connected to the interior of the lower barrel 11, and the air outlet of the motor assembly is connected to the first cavity formed between the float frame 2 and the middle frame 3. Thus, the suction port 12 on the side wall of the barrel 11, the interior of the barrel 11, the motor assembly 4, the first cavity formed between the float frame 2 and the middle frame 3, and the interior of the blower 31 are sequentially connected to form the internal blowing duct of the wet and dry vacuum cleaner. The first cavity is used to pressurize the external air drawn into the internal blowing duct by the motor assembly 4 from the outside, so as to achieve a high-efficiency blowing effect.

[0041] Specifically, when the motor assembly 4 is started, under the suction force of the motor assembly 4, external air enters the interior of the dustbin 1 through the suction port 12 of the dustbin assembly 1, then flows upward, passing successively below the float frame 2 and through the motor assembly 4 into the sealed first cavity formed between the middle frame 3 and the float frame 2 for pressurization, and then is discharged outward at high speed through the blower 31 on the middle frame 3, achieving a highly efficient blowing effect. Through the above structural design, external air can be pressurized by entering the sealed cavity formed between the middle frame 3 and the float frame 2 under the strong suction force of the motor assembly 4 before being discharged outward, significantly improving the blowing speed of the blower 3, resulting in high blowing efficiency and good blowing effect.

[0042] More specifically, a second cavity is formed inside the blower 31, which is connected to the first cavity. After the external air is pressurized in the first cavity, it enters the second cavity, which is much smaller in volume than the first cavity, to achieve secondary pressurization of the air and further improve the blowing efficiency and effect.

[0043] Preferably, see Figure 1 and Figure 2As shown, the head assembly also includes a top cover 7, which is positioned above the middle frame 3. The top cover 7 has a handle 71 and a switch button 72. The top cover 7, located above the middle frame 3, can be fixedly mounted on the middle frame 3, on the float frame 2, or simultaneously on both. After assembling the top cover 7, the user can lift the wet / dry vacuum cleaner using the handle, facilitating vacuuming or blow-drying operations. The switch button on the top cover 7 is electrically connected to the control module and circuit board inside the head assembly, controlling the operating status of the motor assembly 4.

[0044] Further, see Figure 1 As shown, the vacuum bin assembly 1 also includes a buckle 13, which is rotatably mounted on the side wall of the bin body 11. The float frame 2 has a protrusion 23. The buckle 13 engages with the protrusion 23. When the buckle 13 is rotated upwards to engage with the protrusion 23, the float frame 2 is fixed above the bin body 11 by the engagement of the buckle 13. When the buckle 13 is rotated downwards to disengage from the protrusion 23, the float frame 2 can be removed from the top of the bin body 11. With this structural design, the buckle 13 can be rotated downwards to open it, allowing the head assembly to be removed from the vacuum bin assembly 1. After connecting the head assembly to a vacuum hose assembly or other components, it can be reinstalled onto the vacuum bin assembly 1, and the buckle 13 can be rotated upwards to re-engage with the protrusion 23 of the float frame 2. The operation is simple.

[0045] Further, see Figure 2 As shown, the head assembly also includes a float 21. A frame 22 is provided on the side of the float holder 2 facing the inside of the tank, and the float 21 is housed within the frame 22. The frame 22 of the float holder 2 serves to house and accommodate the float 21. The main function of the float 21 is to control the water level in the tank 11, preventing water or other liquids from being sucked into the motor assembly 4, thereby protecting the motor assembly 4 and ensuring the safe operation of the wet / dry vacuum cleaner when handling liquids.

[0046] Example 1

[0047] In a preferred embodiment of this utility model, a specific structural design scheme for the motor assembly 4 is provided.

[0048] See Figure 2As shown, in this embodiment, the motor assembly 4 includes a motor and a fan. The output end of the motor is connected to the fan impeller of the fan to drive the fan impeller to rotate. The air inlet of the fan is connected to the inside of the barrel 11, and the air outlet of the fan is connected to the first cavity formed between the float frame 2 and the middle frame 3. When the motor starts, its output end drives the fan impeller to rotate, thereby generating airflow. This airflow draws air from inside the barrel 11 below the motor assembly 4 through the air inlet of the fan and then discharges it from the air outlet into the first cavity formed between the float frame 2 and the middle frame 3. The resulting high-speed airflow achieves a pressurization effect in the sealed space of the first cavity.

[0049] See Figure 1 and Figure 2 As shown, in a preferred embodiment, the lower cover 5 of the motor is provided with an air inlet 51, which corresponds to the air inlet of the fan, for drawing airflow from the inside of the barrel 11 below the motor assembly 4 into the fan. The air inlet 51 of the lower cover 5 of the motor is provided with a grille for filtering.

[0050] Example 2

[0051] In another preferred embodiment of this utility model, a specific structural design scheme for the head assembly is provided.

[0052] See Figure 2 As shown, in this embodiment, the blower 31 is inclined upwards towards the outside of the middle frame 3. This inclined upward design facilitates the connection of the external vacuum cleaner hose assembly and, compared to horizontal or vertical designs, is more conducive to the overall spatial design of the vacuum cleaner, preventing the vacuum cleaner structure from being too wide or too tall. Furthermore, the blower 31 and the middle frame 3 are an integrated structure, improving the overall structural strength and stability.

[0053] See Figure 2 As shown, in a preferred embodiment, the blower 31 has an air outlet 32 ​​at its outer end, and a connector is provided at the air outlet 32. The blower 31 is connected to the external vacuum hose assembly through this connector. Specifically, since the float frame 2 and the barrel 11 are detachably connected, the head assembly can be removed from the vacuum barrel assembly 1 as needed, and then the vacuum hose assembly or other components can be connected to the connector at the air outlet 32 ​​before being reinstalled on the vacuum barrel assembly 1. The operation is simple. In particular, the connector can be a snap-fit ​​mechanism, which connects the blower 31 and the vacuum hose assembly by engaging with the snap-fit ​​structure of the external vacuum hose assembly. The connector can also be a threaded structure (internal or external thread), and the external vacuum hose assembly can be correspondingly provided with a threaded structure (internal or external thread). The interface of the external vacuum hose assembly can be screwed into the blower 31. The structural design is simple and reasonable, and the operation is convenient.

[0054] In another preferred embodiment, the head assembly also includes sound-absorbing cotton, which is disposed inside the blower tube 31 to reduce airflow noise when high-speed airflow is blown out of the blower tube 31, thereby improving the user experience of the dry and wet vacuum cleaner of this utility model.

[0055] In another preferred embodiment, the head assembly further includes a filter assembly, which is provided inside both the motor assembly 4 and the blower 31. Specifically, the filter assembly of the motor assembly 4 can be located at the fan position, and the filter assemblies inside the motor assembly 4 and the blower 31 are used to capture and filter inhaled dust, liquid, or other debris, ensuring that clean air is discharged from the blower 31.

[0056] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
