[0028] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0029] It should be understood that when the terms "include" and / or "comprises" are used in this specification, they indicate the existence of the stated features, integers, steps, operations, elements or components, but do not exclude the existence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0030] In order to solve the technical problems of poor suction and blowing strength and complex structure of the piston-type blowing and suction structure in the prior art, the present application provides a motor-linked blowing and suction structure, please refer to the attached Figure 1 To Attachment Figure 5 , comprising a chamber tube 1 and a linkage 3, wherein a swing piece 2 is arranged in the chamber tube 1, and the side wall of the swing piece 2 is attached to the inner wall of the chamber tube 1; one end of the linkage 3 is connected to a driving motor 4, and the other end is connected to the swing piece; wherein the linkage 3 follows the rotation of the driving motor 4 so that the swing piece performs a fan-shaped reciprocating motion, so that one open end of the chamber tube 1 forms an effect of suction and blowing;

[0031] In the above embodiment, the driving motor 4 rotates and then drives the linkage member 3. The linkage member 3 serves as a connection structure to enable the pendulum 2 to perform a fan-shaped reciprocating motion in the chamber tube 1. The linkage member 3 plays a role similar to a fan-shaped gear. The pendulum 2 can obtain a larger transmission ratio and torque. Under the same spatial structure, a larger movement amplitude can be obtained, so that the internal and external air pressure balance parameters of the chamber tube 1 can be adjusted with a larger amplitude, and thus a greater suction and blowing effect can be obtained at one opening of the chamber tube 1; and the volume is more compact and the structure is simpler.

[0032] In the specific scheme, a first opening and a second opening are formed at both ends of the chamber tube 1; the end of the linkage 3 away from the drive motor 4 is connected to the pendulum 2 through the first opening; when the pendulum 2 is located at the first extreme position and the second extreme position in the fan-shaped reciprocating motion, an suction and blowing effect is correspondingly formed at the second opening; in order to better illustrate this scheme, for example, when the pendulum 2 is located from the first extreme position to the second extreme position, the air in the chamber tube 1 is discharged from the second opening, thereby forming a blowing effect; conversely, when the pendulum 2 is located from the second extreme position to the first extreme position, the air in the environment is drawn from the second opening into the chamber tube 1, thereby forming an suction effect, and the pendulum 2 reciprocates between the first extreme position and the second extreme position with the cooperation of the drive motor 4 and the linkage 3, thereby achieving suction and blowing effects.

[0033] If a connecting hole is provided on the outer wall of the chamber tube 1, and the swinging of the pendulum 2 is realized by inserting the linkage member 3 into the connecting hole, then during the fan-shaped reciprocating motion, it is easy to cause gas to flow out of the connecting hole, causing the suction and the suction intensity to decrease. Therefore, in this embodiment, the chamber tube 1 is an arc-shaped tube; it also includes an arc bridge member 31, one end of the arc bridge member 31 is connected to the linkage member 3, and the other end is connected to the pendulum 2 through the first opening; the linkage member 3 also includes a rotating shaft 32, and the pendulum 2 performs a fan-shaped reciprocating motion with the rotating shaft 32 as the center of the circle; the center of the arc formed by the chamber tube 1 is the rotating shaft 32 ; It is not difficult to understand that the chamber tube 1 is an arc-shaped tube, which can make the first opening more conducive to the assembly and use of the arc bridge member. The inner arc area in the arc bridge member 31 can avoid the end of the chamber tube 1, and can enable the pendulum 2 to obtain a greater swing interaction, so as to further increase the ability to adjust the air pressure to obtain greater suction and blowing capabilities; It is worth emphasizing that the chamber tube 1 still retains the first opening and the second opening at this time, and does not add any redundant holes or mouth structures to cause premature air leakage and additional air intake to the chamber tube 1 during work, thereby ensuring the stability of the pressure difference generation.

[0034] In a more preferred solution, the end face of the linkage 3 away from the drive motor 4 is an arc surface 33, and the arc surface 33 fits with the inner arc portion 13 formed by the chamber tube 1, so that the relative positions of the linkage 3, the drive motor 4 and the chamber tube 1 are further compressed, and the structure is more compact. In addition, with the cooperation of the linkage 3, the motor and the swing plate 2 with a high transmission ratio and torque, there will be no poor suction and blowing due to the compression of the component assembly space; in a more preferred solution, turntables are provided on both sides of the chamber tube 1, and the turntables correspond to the movable sleeve on the rotating shaft 32, and cover the arc surface 33 and the inner arc portion 13, so that the relative movement between the linkage 3 and the chamber tube 1 is more stable.

[0035] In the specific transmission scheme, an eccentric shaft 5 is sleeved on the output shaft of the driving motor 4, and a first protrusion 34 and a second protrusion 35 are provided at one end of the linkage member 3 close to the driving motor 4, and a preset distance is provided between the first protrusion 34 and the second protrusion 35; the eccentric shaft 5 is located within the preset distance, and reciprocates with the first protrusion 34 and the second protrusion 35 facing each other according to the rotation of the driving motor 4, so as to drive the pendulum 2 to perform reciprocating fan-shaped motion; it is not difficult to understand that the deflection shaft 32 is composed of an assembly disk and an eccentric column 51, the assembly disk is coaxially sleeved on the output shaft of the driving motor 4, and the eccentric column 51 is assembled on the side of the assembly disk away from the driving motor 4, and the central axis of the eccentric column 51 is different from that of the assembly disk, and when the driving motor 4 rotates, the eccentric column 51 forms a first contact position and a second contact position in the direction corresponding to the first protrusion 34 and the second protrusion 35. Specifically, when the eccentric column 51 rotates to the first contact position, the eccentric column 51 abuts against the first protrusion 34, and the linkage member 3 moves based on the rotating shaft 32 The pendulum 2 is swung and the arc bridge member 31 is used to squeeze the pendulum 2, so that the pendulum 2 moves toward the second opening to reach the second extreme position, and the gas in the chamber is discharged from the second opening, which has a blowing effect; in the same mechanism, when the eccentric column 51 rotates to the second contact position, the eccentric column 51 abuts against the second protrusion 35, and the linkage member 3 swings based on the rotating shaft 32 and pulls the pendulum 2 through the arc bridge member 31, so that the pendulum 2 finally moves toward the first opening to reach the first extreme position, and the gas outside the chamber is sucked in from the second opening, which has a suction effect; the above-mentioned cooperation is continuously reciprocated to achieve the effect of cyclic suction and blowing; and based on the abutment between the eccentric column 51 axis and the first protrusion 34 and the second protrusion 35, the chamber tube 1 can generate vibrations of corresponding frequencies, thereby expanding the functionality. In a more optimal solution, a flexible kit 52 is also provided on the eccentric column 51 to prevent excessive collision pressure during abutment, reduce product life, make blowing and suction more streamlined, and eliminate the sound caused by collision.

[0036] In this embodiment, the outer wall of the pendulum piece 2 is also sleeved with a sealing ring 21; the sealing ring 21 can ensure the sealing cooperation between the pendulum piece 2 and the strong tube, and ensure the stability of the air pressure formed by blowing and inhaling.

[0037] In a specific solution, the chamber tube 1 is enclosed by a first tube shell 11 and a second tube shell 12. It can be clearly known from the above embodiments that if the chamber tube 1 is prepared by integral molding, the assembly difficulty of the swing piece 2 is undoubtedly increased. Therefore, by modularizing the chamber tube 1 into the first tube shell 11 and the second tube shell 12, technicians can assemble in the order of the first tube shell 11, the swing piece 2, and the second tube shell 12, which is more efficient.

[0038] In a more optimal solution, in order to improve the sealing problem caused by the modular assembly, the facing joint surfaces of the first tube shell 11 and the second tube shell 12 in this embodiment are provided with sealing grooves 16, and the sealing channel formed by the two sealing grooves 16 is filled with a sealing medium; the sealing medium can be a soft silicone strip or sealing glue, etc., which can ensure the sealing of the chamber tube 1 and avoid affecting the strength of suction and blowing.

[0039] The present application also provides a health care tool, including a main body 6, in which a battery, the aforementioned blowing and suction structure and a main control board are arranged, and a driving motor 4 and a battery are respectively connected to the main control board; the present embodiment includes the features of the aforementioned blowing and suction structure, and thus can have the same beneficial effects and functions as the aforementioned blowing and suction structure;

[0040] In a more preferred solution, one end of the extension tube is connected to the opening of the chamber tube 1, and the other end protrudes out of the outer wall of the main body 6 to form a blowing and suction port 17; the extension tube can be used to arrange the blowing and suction port 17 at any desired position of the main body 6, and the structural arrangement is more flexible.

[0041] The advantages of the utility model are:

[0042] Through the cooperation of linkage parts, chamber tubes and swing pieces, the transmission structure of the present invention is simple, the blowing and suction are more powerful, and the spacing volume, blowing and suction effects are good.

[0043] Any changes that can be conceived by technicians in this field should fall within the protection scope of the present utility model.
