Description

A pet hair handheld vacuum cleaner Technical Field

[0001] The utility model relates to a handheld vacuum cleaner, in particular to a handheld vacuum cleaner for pet hair. Background Art

[0002] Many families keep pets like cats and dogs, and they often have to groom their fur, such as using a razor to shave or a brush to comb through messy hair. During this process, the hair often falls from the pet, spreading everywhere and soiling the surrounding area. Therefore, it's best to use a handheld vacuum cleaner to assist in cleaning up the hair while cleaning it. However, performing these two actions separately can be quite cumbersome. Furthermore, existing handheld vacuum cleaners often have built-in dust bags, resulting in a relatively small storage volume. Hair is fluffy, soft, and easily accumulated. Therefore, using a handheld vacuum cleaner to clean up hair can easily fill up the dust bag too quickly and affect the suction power of the suction motor behind the dust bag. Utility Model

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a pet hair handheld vacuum cleaner which can simultaneously absorb fallen hair while processing hair, and has a large hair absorption and storage volume and hair accumulation does not affect the suction wind force.

[0006] The volute centrifugal fan comprises a volute fixed to the end of a handle and centrifugal blades arranged in the volute. The volute opening of the volute serves as a discharge port, and the suction port is arranged on the front end surface of the volute.

[0007] A driving motor for driving the centrifugal fan blades to rotate is arranged outside the volute.

[0008] The centrifugal fan blades are driven by the driving motor to rotate in the volute, thereby generating suction at the suction port and sucking in the hair, which is then thrown to the discharge port by the centrifugal fan blades and stored in the dust bag.

[0009] The rear end surface of the volute is provided with an installation cavity which encloses the drive motor.

[0010] The volute is provided with an inspection port and a detachable inspection cover for closing the inspection port. The inspection cover closes the inspection port to connect the power supply to the drive motor, and opens the inspection port to disconnect the power supply to the drive motor.

[0019] A pet hair handheld vacuum cleaner, as shown in Figures 1 to 5, is a small electric tool used to help pets groom their hair. Its structure mainly consists of a handle 1, and hair processing accessories 2 and a volute centrifugal fan 3 respectively arranged at both ends of the handle. The handle 1 is a cylindrical straight handle.

[0020] Among them, the volute centrifugal fan 3 includes a volute 31 fixed to the end of the handle 1 and a centrifugal fan blade 32 arranged in the volute. The volute opening of the volute 31 serves as an exhaust port 312, and an external dust bag 4 is provided at the exhaust port. Therefore, the storage volume of the dust bag is not affected by the structure of the handheld vacuum cleaner, and the hair accumulated in the dust bag 4 will not affect the suction force of the volute centrifugal fan; the front end surface of the volute 31 is provided with a suction port 311.

[0021] At the same time, a driving motor 33 for driving the centrifugal fan blades 32 to rotate and a battery pack 34 for powering the driving motor are provided outside the volute 31. The battery pack is mainly used as a DC power supply, and the driving motor 33 can also be selected as an AC motor and directly connected to a power cord for AC power supply; and, an installation cavity 5 is provided on the rear end face of the volute 31 to enclose the driving motor 33 and the battery pack 34.

[0022] In this way, when the centrifugal fan blades 32 are driven by the driving motor 33 and rotate in the volute 31 , suction is generated at the suction port 311 and the hair is sucked in. The hair is then thrown to the discharge port 312 by the centrifugal fan blades 32 and stored in the dust bag 4 .

[0023] The volute 31 is provided with an inspection port and a detachable inspection cover 313 for closing the inspection port. The inspection port and the inspection cover 313 are designed to prevent hair from accidentally accumulating in the volute 31 and obstructing the normal rotation of the centrifugal fan blades 32. The inspection cover 313 can be opened to expose the centrifugal fan blades 32 in the inspection port, thereby facilitating the inspection and cleaning of the interior of the volute 31.

[0024] Moreover, the inspection cover 313 and the drive motor 33 can also form a linkage control, that is, the inspection cover 313 closes the inspection port and connects the power supply of the drive motor 33. At this time, the start of the drive motor 33 can be controlled by the main switch. The inspection cover 313 opens the inspection port and disconnects the power supply of the drive motor 33. At this time, the start of the drive motor 33 cannot be controlled by the main switch. The purpose of this design is mainly to ensure safety in use.

[0025] The hair processing attachment 2 is detachably mounted on the end of the handle 1. In actual use, there are many types of hair processing attachments 2, and these hair processing attachments 2 can be used interchangeably with each other, thereby increasing the functionality of the handheld vacuum cleaner.

[0026] The hair treatment attachment 2 is also provided with a hair suction port 11, and the suction port 311 of the volute centrifugal fan 3 is directly connected to the hair suction port 11 through the hair suction channel 12 in the handle 1. Therefore, while the pet owner uses the hair treatment attachment 2 to help the pet deal with hair, the suction wind force generated by the volute centrifugal fan 3 at the hair suction port 11 can be used to simultaneously suck up the fallen hair, so that the two operations of hair treatment and suction can be performed simultaneously on a handheld vacuum cleaner, which is convenient for operation and can better prevent the fallen hair from flying around and dirtying the surrounding environment.

[0027] This embodiment mainly uses the razor head 21 shown in FIG. 1 and the brush head 22 shown in FIG. 4 as the hair treatment accessory 2 for example description.

[0028] The front end of the razor head 21 is provided with a razor 211, and the razor motor 212 for driving the razor and the razor battery 213 for providing power to the razor motor are provided inside the razor head. The razor battery is usually a dry cell battery. The hair suction port 11 is adjacent to the side of the razor 211. Therefore, the razor 211 of the razor head can shave the pet hair while also promptly sucking the shaved hair through the hair suction port 11.

[0029] The front end of the brush head 22 is provided with densely planted bristles 222 and a movably installed grooming plate 221, and the hair suction port 11 is arranged between the bristles 222. When the bristles 222 are combing the pet's hair, they will adhere to the hair. At this time, the grooming plate 221 can be moved outward to push the hair off the bristles 222, and then the hair suction port 11 can be used to absorb the fallen hair in time.

[0030] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included in the protection scope of the present invention.
