Description

Technical Field

[0001] The present invention relates to the technical field of pet products, and in particular to a switching device and a pet blowing and sucking all-in-one machine. Background Art

[0002] With the progress of society and the improvement of living standards, more and more people are starting to keep pets. The most common pet cats or pet dogs often have relatively thick hair. In order to make pet cats and dogs more tidy and clean, they need to be bathed and trimmed regularly. Because the hair of pet cats and dogs is thick and moisture is not easy to evaporate, after bathing them, in order to prevent them from catching a cold, they need to dry their hair, which requires the use of a pet hair dryer. In addition, in the process of trimming the hair of pet cats and dogs, the fallen hair will fly into the surrounding environment, and the hair needs to be swept and cleaned later, so a hair suction device can be used to clean the hair. The existing integrated device for pet hair suction and drying has two functions: hair suction and drying. The hair suction and drying use the same air duct, that is, the air inlet and the air outlet must pass through the same air duct regardless of the mode, and the air duct is usually designed to be straight.

[0003] Existing pet hair vacuuming and drying devices have the following drawbacks: after vacuuming cat and dog hair, a certain amount of pet hair accumulates in the dust bin of the vacuum component. When the hair reaches a certain amount, the dust bin filter becomes clogged. When drying hair, the air inlet and outlet still need to pass through the dust bin, resulting in poor air circulation, which significantly reduces the drying effect and weakens the drying effect, leading to low hair drying efficiency. Summary of the Invention

[0004] To this end, the technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a switching device and a pet blowing and sucking machine. The switching device can realize the switching of the air duct, thereby realizing the change of the air circulation path in different modes. When the switching device is assembled to the pet blowing and sucking machine, the air inlet in the blowing mode and the hair suction mode can be switched, thereby switching different air ducts in different modes, so that the air inlets in the blowing mode and the hair suction mode are independent of each other, thereby avoiding the problem of blocked air ducts when performing blowing operations, and can effectively improve the smoothness of air circulation in the blowing mode, effectively improve the blowing speed, thereby ensuring the blowing efficiency and blowing speed.

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0038] Example 1

[0039] Reference Figures 1 to 11 As shown, the present invention discloses a switching device for a pet blowing and sucking machine, the switching device includes a first cavity 1, which is provided with a first through hole 10, the first through hole 10 is arranged on the side wall of the first cavity 1, and the upper end of the first cavity 1 has an opening.

[0040] The switching device further includes a second cavity 2, which is connected to the first cavity 1 and is provided with a second through hole 20, at least one first air inlet 21, and a first air outlet 22. The second through hole 20 is in communication with the first through hole 10, so that the first cavity 1 and the second cavity 2 are in communication with each other through the first through hole 10 and the second through hole 20.

[0041] The switching device further includes a rotating assembly, which includes a rotating member, and the rotating member is disposed in the second cavity 2 and is rotatably connected to the second cavity 2. The rotating member is movably connected to the first through hole 10 and the first air inlet 21;

[0042] It should be noted that when the rotating part rotates to cover the second through hole 20, the first air inlet 21 is opened. At this time, the first cavity 1 and the second cavity 2 are not connected, and the second cavity 2 is connected to the outside through the first air inlet 21. This mode is defined as the first mode; when the rotating part rotates to cover the first air inlet 21, the second through hole 20 is connected to the first cavity 1. At this time, the first cavity 1 and the second cavity 2 are connected. This mode is defined as the second mode.

[0043] From this, it can be seen that the switching device to be protected by the present invention is provided with a first cavity, a second cavity and a rotating assembly, wherein the rotating assembly includes a rotating part arranged in the second cavity, and the adjustment and switching between two different air circulation paths are achieved by rotating the position of the rotating part. When the rotating part rotates to cover the second through hole, the first air inlet is in an open state. At this time, the first cavity and the second cavity are not connected, and the second cavity is connected to the outside through the first air inlet; when the rotating part rotates to cover the first air inlet, at this time, the second through hole is connected to the first through hole, thereby connecting the first cavity and the second cavity. The switching device can be used to switch the air duct, thereby realizing the change of the air circulation path in different modes. When the switching device is assembled to the pet blowing and sucking machine, the air inlet in the blowing mode and the hair suction mode can be switched, thereby switching different air ducts in different modes, making the air inlets in the drying mode and the hair suction mode independent of each other, thereby avoiding the problem of blocked air ducts during the blowing operation, ensuring the blowing intensity, and effectively improving the smoothness of air circulation in the blowing mode, thereby effectively improving the drying speed of pet hair and ensuring the blowing efficiency and drying speed.

[0044] In a preferred embodiment, the second cavity 2 is cylindrical, and has a first opening and a second opening at its ends. The rotating member includes a movable baffle 30, a first connecting portion 31, and a second connecting portion 32. The first connecting portion 31 is provided at the first opening, and the second connecting portion 32 is provided at the second opening. The ends of the movable baffle 30 are connected to the first connecting portion 31 and the second connecting portion 32, respectively.

[0045] Furthermore, one end of the second cavity 2 is provided with a raised portion 23 for limiting position, and the first connecting portion 31 is provided with a first stopper 310 that cooperates with the raised portion 23. The first stopper 310 is movable along the extension direction of the raised portion 23 and is limited to the raised portion 23. Specifically, the raised portion 23 is radially projecting along the second cavity 2 and extends circumferentially along the second cavity 2, with the raised portion 23 forming a quarter-circular arc. Thus, the first stopper 310 cooperates with the raised portion 23 to limit the movement trajectory of the first connecting portion 31, allowing it to rotate 90° around the axis of the second cavity 2. Furthermore, because the movable baffle 30 is fixed to the first connecting portion 31 and also to the second connecting portion 32, the movable baffle 30, the first connecting portion 31, and the second connecting portion 32 can rotate synchronously.

[0046] It should be noted that when the first stopper 310 is located at one end of the raised portion 23, the movable baffle 30 can completely cover the second through hole 20, and the first air inlet 21 can be fully opened, thereby disconnecting the first cavity 1 and the second cavity 2, and forming an air duct between the first air inlet 21 and the first air outlet 22. Conversely, when the connector 3 is rotated so that the first stopper 310 is located at the other end of the raised portion 23, the movable baffle 30 can be rotated from the second through hole 20 to the first air inlet 21, covering the first air inlet 21, thereby connecting the first cavity 1 and the second cavity 2, further forming an air duct between the second through hole 20 and the first air outlet 22, and disconnecting the air duct between the first air inlet 21 and the first air outlet 22, thereby achieving switching back and forth between the first mode and the second mode.

[0047] Furthermore, the rotation assembly further includes a knob 33, which is mounted on the first connecting portion 31 and, for ease of operation, is located outside the second cavity 2. Rotating the knob 33 causes the movable baffle 30, the first connecting portion 31, and the second connecting portion 32 to rotate synchronously. In a preferred embodiment, one end of the knob 33's grip is positioned adjacent to the first stopper 310.

[0048] Specifically, the switching device also includes a micro switch 24 arranged outside the second cavity 2, and a second stopper 320 is provided on the second connecting part 32. When the second connecting part 32 rotates, the second stopper 320 can rotate with the second connecting part 32 to trigger the micro switch.

[0049] As a preferred embodiment, the first mode is a blowing mode, and the second mode is a hair-sucking mode. Since blowing mode typically requires a higher power output, approximately 1200-2000W, while hair-sucking mode uses a power output of approximately 400-500W, the microswitch is linked to the control unit to switch the output power between different modes, thereby adapting to different needs and application scenarios.

[0050] Example 2

[0051] The present invention also discloses a pet blower and vacuum machine, comprising a housing 4, a dust cup unit, a fan unit 40 and the switching device as described above, provided on the housing 4, wherein:

[0052] The housing 4 includes a base and an upper cover. The housing 4 is provided with a housing air inlet 41 and a housing air outlet 42. The dust cup unit is connected to the housing air inlet 41 and the switching device. The first air outlet 22 of the switching device is connected to the fan unit 40. At the same time, the fan unit 40 is connected to the housing air outlet 42.

[0053] Furthermore, the dust cup unit includes a dust cup body 5 and a filter element, the filter element is arranged in the dust cup body 5, the dust cup body 5 includes a dust cup air inlet 51 and a dust cup air outlet 52, the dust cup air inlet 51 is connected to the shell air inlet 41, and the dust cup air outlet 52 is connected to the first cavity 1.

[0054] In this way, a vacuum hose assembly is provided at the air inlet 41 of the shell to achieve the adsorption and collection of pet cat and dog hair. When the machine is turned on, the pet hair enters the dust cup body 5 through the vacuum hose assembly and is collected in the dust cup body 5 under the action of the filter element, thereby achieving the collection and cleaning of pet cat and dog hair.

[0055] As a preferred embodiment, the filter element includes filter cotton and HEPA, the filter cotton is arranged in the dust cup body 5, and the HEPA is arranged in the first cavity 1.

[0056] In detail, the pet blower and vacuum machine also includes a heating unit, which includes at least one heating plate 401 provided on the fan unit 40. Specifically, the heating plate 401 is provided at the output end of the fan unit 40, thereby heating the air blown out by the fan unit 40 and improving the drying efficiency of pet cats and dogs.

[0057] Furthermore, an air intake assembly is provided on the housing 4 near the first air inlet 21 of the switching device. The air intake assembly includes an air intake grille 43 and a plurality of air intake holes 44, arranged sequentially from the inside to the outside. When the pet blower / vacuum unit is adjusted to the blowing mode, fresh air from the outside enters the housing 4 through the air intake assembly, then enters the fan unit 40 through the first air inlet 21. Thereafter, the fan unit 40 generates normal temperature air or hot air, which is then output through the housing outlet 42.

[0058] In detail, the pet blower and vacuum machine also includes a control unit, which includes a control circuit board 6 disposed in the housing 4. The control circuit board 6 is connected to the micro switch 23 of the switching device and is also connected to the fan unit 40. Thus, the micro switch 23 is used to switch between different modes and control the output power of the fan unit 40, thereby adapting to different application scenarios.

[0059] As a preferred embodiment, the housing 4 is further provided with a grip 45 , which is designed as an ergonomic handle to facilitate handling. The grip 45 is provided with an adjustment knob 46 and a switch 47 .

[0060] In summary, the pet blower and vacuum cleaner equipped with the switching device can switch the air inlet between the blowing mode and the hair suction mode, thereby switching the air duct between the different modes. The air inlets in the blowing mode and the hair suction mode are independent of each other. In this way, in the blowing mode, the incoming air does not need to pass through the dust barrel unit, thus avoiding the problem of blocked air ducts during the blowing operation, ensuring the blowing intensity and effectively improving the smoothness of air circulation in the blowing mode, thereby effectively improving the drying speed of pet hair and ensuring the blowing efficiency and drying speed.

[0061] At the same time, the pet blowing and sucking machine of the present invention only needs to set up a fan unit, and then cooperate with the switching device to switch the air duct to achieve switching between different modes. From the overall structural point of view, while ensuring the perfect function, the structure is also simplified.

[0062] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
