DETAILED DESCRIPTION

[0025] In order to better understand the present invention, the preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood by those skilled in the art that these exemplary embodiments do not mean any limitation to the form of the present invention.

[0026] Reference Figure 1 -11. The present invention provides a two-joint battery-type blower and sucker, comprising a main body casing 1, a blowing port 8 is arranged at the front end of the main body casing 1, a lighting lamp 36 for providing illumination is arranged below the blowing port 8, and an air suction port 9 is arranged on the side of the main body casing 1. Air flow enters from the air suction port 9 and is blown out from the blowing port 8 to form an air flow channel. It also comprises a handle for hand-holding, a battery mounting seat 4 for mounting a battery pack 11 is arranged at the bottom of the handle, and a switch 12 for controlling the start and stop of blowing and sucking is arranged on the handle. The battery-type blower and sucker can be used for two purposes: when used as a hair dryer, the blowing port 8 is connected to the blowing pipe 5, and the air suction port 9 is suspended in the air, so as to blow away dust, fallen leaves, etc.; when used as a vacuum cleaner, the air suction port 9 is connected to the air suction pipe 6, and the blowing port 8 is connected to the dust bag 7, so as to suck away dust, fine garbage, etc.

[0027] In order to adapt to the actual complex working environment, an intermediate connecting part 3 connecting the main housing 1 and the handle is provided. The main housing 1 and the handle can rotate in two different directions around the intermediate connecting part 3. Preferably, the rotation directions of the main housing 1 and the handle around the intermediate connecting part 3 are perpendicular to each other and are 90°.

[0028] A casing ring 22 is arranged at the center of the intermediate connecting portion 3, and the main casing 1 cooperates with the casing ring 22 to rotate to change the blowing direction of the main casing 1, and the adjustment angle between the main casing 1 and the intermediate connecting portion 3 is θ, 0°≤θ<360°, and a handle rotating shaft 18 is arranged on the upper part of the casing ring 22, and the handle cooperates with the handle rotating shaft 18 to change the holding angle, and the adjustment angle between the handle and the intermediate connecting portion 3 is α, 0°≤α≤180°.

[0029] Specifically, a motor fixing housing 16 is provided on the side of the main housing 1 opposite to the air inlet 9, an impeller is provided inside the main housing 1, and a motor connected to the impeller is provided inside the motor fixing housing 16. Driven by the motor, the impeller generates airflow. The motor fixing housing 16 is provided with a rotating gear ring 17 having at least two tooth grooves 24 in the circumferential direction, which is used to lock the rotation position of the main housing 1. Shaft rings 13 are provided on both sides of the rotating gear ring 17 to prevent axial displacement and fix the main housing 1 on the housing sleeve ring 22 of the intermediate connecting portion 3.

[0030] The casing ring 22 of the intermediate connecting portion 3 cooperates with the rotating gear ring 17 of the main casing 1 , the outer diameter of the rotating gear ring 17 is less than or equal to the inner diameter of the casing ring 22 , and the outer diameter of the shaft ring 13 is greater than the inner diameter of the casing ring 22 .

[0031] In order to lock the rotational position of the main casing 1, a rotation locking bracket 27 is provided on the casing ring 22, and a rotation locking member 30 is provided inside the rotation locking bracket 27. A locking gear 29 is provided at one end of the rotation locking member 30, and the locking gear 29 is inserted into the tooth groove 24 on the rotation gear ring 17 through the notch on the casing ring 22 to lock the rotation angle of the main casing 1. The middle opening of the rotation locking member 30 is hinged on the rotation locking bracket 27, and the other end of the rotation locking member 30 presses upward against the casing rotation button 31 installed on the rotation locking bracket 27, and presses downward against the first reset spring 32 set on the casing ring 22. When the casing rotation button 31 is pressed, the locking gear 29 is driven to disengage from the tooth groove 24, and the main casing 1 is released from the locked state and can rotate freely; when the casing rotation button 31 is released, under the action of the first return spring 32, the locking gear 29 is re-engaged in the tooth groove 24, and the locking state of the main casing 1 is restored.

[0032] The lower part of the housing ring 22 is provided with an annular lower groove 26 coaxial with the handle shaft 18, the handle shaft 18 is provided with an annular upper groove 25, the upper part of the upper groove 25 is provided with a rotation locking ring 19 that can move up and down but cannot rotate, the upper end surface of the rotation locking ring 19 is provided with at least two locking grooves 20, and a second return spring 21 is provided between the rotation locking ring 19 and the upper groove 25. The number and position of the locking grooves 20 determine the rotatable angle of the handle.

[0033] Specifically, the handle shaft 18 is set as a "cross" shaft, and a "cross" hole is set in the middle of the rotation locking ring 19, so that the rotation locking ring 19 can move up and down while preventing rotation. It can be understood that the handle shaft 18 can also be set as a round shaft with a square, and a round hole with a square is set in the middle of the rotation locking ring 19, so that the rotation locking ring 19 can move up and down while preventing rotation.

[0034] The handle is provided with a grip 2, which is the position where the user holds the hand and is very convenient for controlling the switch 12. An upper connecting rod 14 is provided above the grip 2, and a handle sleeve 23 is provided at the front end of the upper connecting rod 14 to cooperate with the handle shaft 18. Fig.10 and 11 As shown, an upper snap ring 33 is arranged in the handle sleeve 23, which is buckled into the upper slot 25 of the handle shaft 18. A handle rotation button 10 is arranged at the top of the handle sleeve 23, which is sleeved on the handle shaft 18. A limit ring 34 is also arranged in the handle sleeve 23, which is located between the handle rotation button 10 and the rotation locking ring 19. The limit ring 34 sets the highest position of the rotation locking ring 19 and also limits the lowest position of the handle rotation button 10. At least one locking boss 35 is arranged at the lower end of the limit ring 34, and the locking boss 35 is engaged with the locking groove 20 on the rotation locking ring 19, thereby locking the angle of the handle. A lower connecting rod 15 is arranged below the handle 2, and a lower snap ring 28 is arranged at the front end of the lower connecting rod 15, and the lower snap ring 28 is buckled into the lower slot 26 of the intermediate connecting part 3. When the handle rotation button 10 is pressed, the rotation locking ring 19 is driven downward, the locking groove 20 on the rotation locking ring 19 is disengaged from the locking boss 35 at the lower end of the limit ring 34, and the handle is released from the locked state and can rotate freely; when the handle rotation button 10 is released, under the action of the second return spring 21, the rotation locking ring 19 moves upward, and the locking boss 35 is re-engaged in the locking groove 20, restoring the locking state of the handle.

[0035] It is understandable that at least one locking boss 35 can be set on the upper end surface of the rotating locking ring 19, and at least two locking grooves 20 can be set on the lower end surface of the limiting ring 34. The locking boss 35 engages with the locking groove 20 to lock the rotation angle of the handle.

[0036] In addition to the above preferred embodiments, the present invention has other implementation modes. Those skilled in the art may make various changes and modifications based on the present invention. As long as they do not depart from the spirit of the present invention, they should all fall within the scope defined by the claims attached to the present invention.
