Description

Technical Field

[0001] The utility model relates to the technical field of compression pumps, and more specifically to an ultra-micro air-conditioning compressor. Background Art

[0002] There are many types of air compression pumps, which can be divided into volumetric compression pumps and velocity compression pumps according to their working principles. The working principle of a volumetric compression pump is to compress the volume of gas, increase the density of gas molecules per unit volume to increase the pressure of the compressed air, and the working principle of a velocity compression pump is to increase the movement speed of gas molecules, convert the kinetic energy of gas molecules into the pressure energy of gas, thereby increasing the pressure of compressed air.

[0003] The Chinese patent with publication number CN218151419U discloses a high-efficiency vortex compression pump head, which limits the rotation angle of the moving plate by inserting an eccentric sleeve cylindrical pin on the positioning sleeve, and then through the rotational connection between the cavity and the transition ring, the rotational connection between the transition ring and the gourd shaft, and the rotational connection between the gourd shaft and the moving plate, the rotation of the connection between the moving plate and the cavity is very smooth, reducing the friction at the connection between the moving plate and the cavity and improving work efficiency.

[0004] However, in the above patent, the moving plate and the cavity need to be connected through a transition ring and a hoist shaft, and the moving plate can only be driven to rotate eccentrically through a number of eccentric sleeve cylindrical pins. These connection methods make the device complicated, making it difficult to make the device small enough to make a micro air-conditioning compressor.

[0005] The utility model can provide a device with a simple structure without complicated small parts, and can be made to have a more minute function. Utility Model Content

[0029] An air inlet groove 501 is respectively provided on the outer side of both ends of the top and bottom of the moving disk 5, and the two air inlet grooves 501 are located in the same vertical position.

[0030] A first limiting slot 502 is provided on the outer side of the moving disk 5, a second limiting slot 603 is provided on the inner side of the chamber 6, a seesaw 4 is installed in the first limiting slot 502 and the second limiting slot 603, a plurality of limiting slots 702 are provided on the top of the chassis 7, a plurality of positioning pins 3 are installed in the limiting slots 702, a seesaw 4 is sleeved on the outer side of the positioning pins 3 on the rear side, and the first limiting slot 502 and the second limiting slot 603 are used to provide an installation position for the seesaw 4; the positioning pins 3 and the limiting slots 702 are used to limit the position of the seesaw 4 and the position of the upper cover 2; and the seesaw 4 is used to cooperate with the moving disk 5 to separate the compressed air chamber 602.

[0031] In the embodiment of the utility model, the eccentric shaft 9 includes: a first shaft 901, a connecting block 902 and a second shaft 903. The connecting block 902 is installed in the center of the chassis 7, the first shaft 901 is installed on the top of the connecting block 902, and the second shaft 903 is installed in the center of the bottom of the connecting block 902. The axis of the first shaft 901 deviates from the axis of the second shaft 903 by a distance, and the eccentricity between the first shaft 901 and the second shaft 903 is 0.5 mm, so that when the first shaft 901 rotates, the second shaft 903 rotates around the axis of the first shaft 901 of the eccentric shaft 9.

[0032] In the embodiment of the utility model, an air outlet hole 201 is opened through the top surface of the upper cover 2, the air outlet hole is located on the left side of the top of the rocker 4, the air inlet groove 501 is located on the right side of the rocker 4, and a plurality of air inlet holes 703 are opened around the top surface of the bottom cover at equal intervals to achieve the effect of air intake and exhaust.

[0033] In the embodiment of the utility model, a compressed air chamber 602 is opened through the center of the chamber 6. The diameter of the compressed air chamber 602 is 1 mm larger than that of the moving disk 5, so that the moving disk 5 always has one side in contact with the compressed air chamber 602 under the drive of the eccentric shaft 9.

[0035] Working principle: The electric drive eccentric shaft 9 is rotated by the rotation of the motor. The eccentric design of the eccentric shaft 9 makes the second shaft 903 rotate around the axis of the first shaft 901 of the eccentric shaft 9 when the first shaft 901 rotates, thereby driving the movable plate 5 to rotate around the axis of the first shaft 901 of the eccentric shaft 9. When the eccentric shaft 9 rotates, the space on the left side of the seesaw 4 becomes larger. At this time, the air pressure on the right side of the seesaw 4 becomes lower. Because the air inlet groove 501 is located on the right side of the seesaw 4, the air from the outside will enter the inside of the movable plate 5 through the air inlet hole 703, and then enter the cavity on the left side of the seesaw 4 through the air inlet groove 501 and the air suction hole 504. As the eccentric shaft 9 continues to rotate, the movable plate 5 After the contact surface between the disk 5 and the compressed air cavity 602 rotates past the air inlet groove 501, the gas at this time cannot enter the original cavity because the air inlet groove 501 and the compressed air cavity 602 are tightly fitted, and can only enter the newly formed air cavity after the contact surface between the moving disk 5 and the compressed air cavity 602 rotates past the air inlet groove 501. The eccentric shaft 9 then rotates, and the original cavity continues to shrink under the action of the moving disk 5, squeezing the gas and pumping it out from the air outlet hole 201, while the new cavity continues to grow larger, sucking in air, and then as the eccentric shaft 9 rotates, the air is pumped out from the air outlet hole 201 in the new cavity under the action of the moving disk 5, and the next new cavity is generated, and this cycle is repeated to continuously pump out the gas.
