Description

Technical Field

[0001] This utility model relates to the field of mite removal devices, and in particular to a rear-mounted air intake structure for a mite removal device motor. Background Technology

[0002] In the world of cleaning appliances, it's well-known that mite removers with different structural designs are used to vacuum and remove mites from surfaces. These mite removers utilize an electric motor to drive a high-speed fan, creating a partial vacuum inside the dust collection chamber. This pressure difference with the outside of the chamber generates airflow, drawing dust into the chamber. After filtration, the dust is retained inside the chamber, while clean air is discharged. Mite removers often integrate the motor and fan into a single unit, resulting in a more compact structure.

[0003] Currently, the motor air inlet and outlet of mite removers are front-mounted. That is, the motor air inlet faces the direction of the main unit's suction, and the air is mostly led out directly from the motor cover. The disadvantage of this is that the motor noise is relatively large. Utility Model Content

[0004] The purpose of this utility model is to provide a rear-mounted air intake structure for the motor of a mite remover in order to solve the problem of excessive noise from the motor.

[0005] To achieve the above objectives, this utility model provides a rear-mounted air intake structure for a mite remover motor, comprising a mite remover body, a motor, and a motor cover. A roller brush is provided at the front end of the mite remover body. A first air inlet is provided at one end of the mite remover body located on the roller brush. A second air inlet is provided at the end of the mite remover body away from the roller brush. The motor is built into the mite remover body, and the motor cover encloses the motor. A third air inlet is provided on the motor cover, which is connected to the second air inlet via an air duct. At least one first air outlet is provided on the motor cover, and at least one second air outlet is provided on the mite remover body. The positions of the first air outlet and the second air outlet are offset from each other.

[0006] As a further description of the above technical solution:

[0007] The angle between the orientation of the first air inlet and the orientation of the third air inlet is greater than 90° and less than or equal to 180°.

[0008] As a further description of the above technical solution:

[0009] The mite remover has a second air outlet on both sides and at the bottom of its main body.

[0010] As a further description of the above technical solution:

[0011] The bottom of the mite remover body is provided with a groove, and a second air outlet is provided in the groove.

[0012] As a further description of the above technical solution:

[0013] A roller is provided on one side of the groove.

[0014] As a further description of the above technical solution:

[0015] The mite remover body has a handle at the end away from the roller brush, and the second air inlet is located on one side of the upper part of the handle.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: This utility model, by opening a second air inlet at the rear of the machine shaft as the air inlet for the motor, and the angle between the orientation of the first air inlet and the orientation of the third air inlet being greater than 90° and less than or equal to 180°, constitutes a rear-mounted air inlet structure. The motor is horizontally positioned, with an angle of 180°. Besides being horizontally positioned, the motor can also be tilted relative to the horizontal plane, with the angle between 90° and 180°. Simultaneously, the air outlet abandons the original structure of directly venting air from inside the motor housing. By offsetting the first air outlet of the motor housing with the second air outlet of the mite remover body, the direct external emission of motor noise is effectively reduced, achieving noise reduction. Since the air outlet is not constrained by the size of the motor housing, the air outlet area can be greatly increased, and the air resistance is effectively reduced, thus improving the overall working efficiency of the machine.

[0027] Please see Figure 1-2This utility model provides a rear-mounted air intake structure for a mite remover motor, including a mite remover body 1, a motor 2, and a motor cover 3. A roller brush 4 is provided at the front end of the mite remover body 1. A first air inlet 5 is provided at one end of the mite remover body 1 located at the roller brush 4. A second air inlet 6 is provided at the end of the mite remover body 1 away from the roller brush 4. The motor 2 is built into the mite remover body 1. The motor cover 3 covers the motor 2. A third air inlet 7 is provided on the motor cover 3. The third air inlet 7 is connected to the second air inlet 6 through an air duct 8. At least one first air outlet is provided on the motor cover 3. At least one second air outlet 9 is provided on the mite remover body 1. The positions of the first air outlet and the second air outlet 9 are offset from each other.

[0028] The angle between the orientation of the first air inlet 5 and the orientation of the third air inlet 7 is greater than 90° and less than or equal to 180°. In this embodiment, the angle is 180°, and the motor is horizontally arranged. In another embodiment, the motor can be horizontally arranged or tilted relative to the horizontal plane. That is, the angle between the orientation of the first air inlet and the orientation of the third air inlet is greater than 90° and less than 180°.

[0029] The mite remover body 1 has second air outlets 9 on both sides and at the bottom, which can increase the air outlet area.

[0030] The bottom of the mite remover body 1 is provided with a groove 10, and a second air outlet 9 is provided in the groove 10. The shape of the second air outlet can be round, elliptical, or other forms, which can not only provide downward hot air output to the machine, but also prevent the air outlet from being blocked and improve the air output efficiency.

[0031] A roller 11 is provided on one side of the groove 10. The roller can lift the mite remover body 1 a certain distance to facilitate air outlet at the bottom and also facilitate the movement of the mite remover body.

[0032] The mite remover body 1 is provided with a handle 12 at the end away from the roller brush, and the second air inlet 6 is located on one side of the upper part of the handle 12.

[0033] Working Principle: This invention utilizes a second air inlet located at the rear of the machine's shaft as the motor's air inlet. The orientation of the first air inlet is 180° to that of the third air inlet, creating a rear-mounted air inlet structure. In this configuration, the motor is horizontally positioned. Alternatively, in another implementation, the motor can be tilted relative to the horizontal plane, with the angle between the orientations of the first and third air inlets greater than 90° and less than 180°. Simultaneously, the air outlet design abandons the traditional direct exhaust from within the motor housing. By offsetting the first air outlet of the motor housing with the second air outlet of the mite remover's main body, the direct exhaust noise of the motor is effectively reduced, achieving noise reduction. Since the exhaust is not constrained by the size of the motor housing, the exhaust area can be significantly increased, while the air resistance is effectively reduced, thus improving the overall machine efficiency.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
