Description

Technical Field

[0001] The invention relates to a motor, in particular to a motor with separable carbon powder. Background Art

[0002] By using a motor to drive the gas flow and pump it into the water body, you can oxygenate the water and even stir the water, creating bubbles, splashes and waves in the water. If you stir the water in a swimming pool, it can bring a surfing feeling, making you feel refreshed and relieve fatigue.

[0003] Motors can be divided into two categories: brushed motors and brushless motors. Since the manufacturing cost of a brushless motor of the same power is 5-10 times that of a brushed motor, brushed motors are more commonly used in pools.

[0004] The brushed motor relies on the carbon brush and commutator to maintain normal operation. The carbon brush maintains close contact with the commutator through the pressure of the spring. When the rotor rotates, the carbon brush will continue to wear under the action of friction, forming carbon powder. If the carbon powder is mixed into the pool with the airflow, it will inevitably cause serious pollution to the water quality. The current solution is to set a filter at the end of the air outlet, but it can only filter part of the carbon powder, and there will still be tiny carbon powder entering the pool. In addition, the setting of the filter needs to consider the replacement problem, and the structural changes to the pool are relatively large, which makes the product structure complicated. Therefore, there is no effective solution to the carbon powder pollution problem of brushed motors. Summary of the invention

[0005] The present invention provides a motor capable of separating carbon powder, which can effectively separate carbon powder. The technical solution adopted by the present invention to solve its technical problem is:

When the impeller rotates, external air is drawn into the casing through the air inlet and then discharged along the air outlet. The casing also includes a dust cover which is arranged in the casing and covers the connection part between the carbon brush and the commutator. The dust cover is a structure with openings at both ends, one end opening covers the commutator, and the other end opening butts against the rear end face of the casing. A carbon brush through hole for making way for the carbon brush is provided on the side wall, and a dust collection hole is provided on the rear end face of the casing.

[0007] In a preferred embodiment: The inner cavity of the dust cover is conical, and the width is larger closer to the rear end face of the housing.

[0008] In a preferred embodiment: At the position where the other end opening of the dust cover faces the carbon brush, it expands outward to form an arc-shaped ear portion, and the dust collection hole is exactly opposite to the ear portion; One end opening of the dust cover has a lip that turns inward.

[0009] In a preferred embodiment: The dust cover is locked to the housing; The other end opening of the dust cover is provided with positioning posts, and the positioning posts are inserted into the housing.

[0010] In a preferred embodiment: The housing includes a main body and a support plate. The main body is in the shape of a shell with an opening at the front end face. The support plate is connected to the opening of the main body. The part of the opening of the main body not covered by the support plate forms the air passing hole, and the air outlet is arranged on the rear end face and / or side wall of the main body.

[0011] In a preferred embodiment: The opening at the front end face of the main body is turned outward and folded perpendicular to the side wall to form a positioning ring. One side end face of the air hood is open and sleeved on the positioning ring, and the air inlet is arranged at the center of the other side end face.

[0012] In a preferred embodiment: The other end face of the air hood is a conical surface and protrudes outward.

[0013] In a preferred embodiment: The impeller includes a front panel, a rear panel, and a plurality of blades connected between the front panel and the rear panel.

A suction hole is provided in the middle of the front panel, and the suction hole is exactly opposite to the air inlet; The outer shape of the front panel is in the shape of a flat horn, and the suction hole protrudes forward. The rotational speed range of the impeller is 22,000 - 35,000 revolutions per minute.

[0014] In a preferred embodiment: It further includes a guide wheel connected between the housing and the impeller. The guide wheel includes a baffle and a plurality of guide plates. The front surface of the baffle faces the rear panel of the impeller. The guide plates are arc-shaped, and these guide plates are circularly arrayed around the central axis of the baffle on the rear surface of the baffle.

[0015] In a preferred embodiment: The guide wheel further includes a plurality of inclined blocks, and these inclined blocks are circularly arrayed around the central axis of the baffle on the rear surface of the baffle. The inclined blocks are connected to the outside of the guide plates.

[0016] Compared with the background technology, this technical solution has the following advantages:

[0017] 1. The dust cover is arranged in the housing and covers the part where the carbon brush is connected to the commutator. When working, the carbon powder generated by the high-speed friction between the commutator and the carbon brush flies out around the commutator under the action of centrifugal force and is blocked by the dust cover. The impeller rotates to draw the external air into the motor, and most of the airflow is discharged from the air outlet. It can be connected to the pool through the gas pipeline (it can be directly connected to the water body, or connected to the bottom of the pool, a large amount of gas is pumped into the water body or the bottom of the pool to achieve the purpose of stirring the water body, thereby forming waves and water splashes). A small part of the airflow enters the dust cover, and the carbon powder is discharged from the dust collection hole driven by the airflow and collected at a designated location. In the present invention, since the dust cover can cover the part where the carbon brush is connected to the commutator, the carbon powder is isolated, and the airflow in the motor is separated into two paths. One path does not enter the dust cover and is directly output for wave making, and the other path enters the dust cover to take away the dust, thereby preventing the dust from being output from the air outlet and avoiding water pollution. Furthermore, the dust cover is arranged inside the motor, and no additional modification is required to the structure of the water tank.

[0018] 2. The dust cover adopts a conical inner cavity, which can prevent the airflow in the inner cavity of the dust cover from flowing back and effectively prevent dust from floating out from one end opening.

[0019] 3. The opening at one end of the dust cover has an inward-folded lip, which can reduce the gap between the commutator and the dust cover, so that a large amount of airflow is used for work, and only a small part of the airflow enters the dust cover, avoiding excessive air pressure in the dust cover causing dust to fly around.

[0020] 4. The other end opening of the dust cover is provided with a positioning column which is plugged into the housing to facilitate assembly into the ear portion and docking with the dust collection hole.

[0021] 5. The housing includes a body and a support plate. The vertical side wall of the opening on the front end of the body is folded outward to form a positioning ring, which is conducive to the gas pipeline covering the body and guiding the air flow into the pool or water body, making it easy to use and install.

[0022] 6. The other end face of the wind hood is a conical face and convex outward, which is conducive to guiding the air, making the pressure difference between the inside and outside of the wind hood larger, and making it easier for air to enter the wind hood.

[0023] 7. The impeller includes a front panel, a rear panel and a plurality of blades connected between the front panel and the rear panel. When the impeller rotates at a high speed, a spiral airflow is formed, which generates a greater suction force and is conducive to the air being sucked in from the outside. In particular, the front panel is in a flat trumpet shape, convex forward, which is also conducive to the guidance of the air. The speed range of the impeller is 22,000 to 35,000 rpm. When working, negative pressure is formed at the air inlet position, thereby forming a strong suction force.

[0024] 8. The impeller stirs the airflow to form a spiral airflow, and the guide plate of the guide wheel guides the air volume so that the air volume enters the casing more smoothly. Brief Description of the Drawings
