The driving unit 121 may rotate under the control of the control unit 30. The driving unit 121 may be connected to the shaft 1222, and the shaft 1222 may rotate as the driving unit 121 rotates. A bearing 1223 may be disposed between the shaft 1222 and the dispenser 10. As the bearing 1223 is disposed between the shaft 1222 and the dispenser 10, the shaft 1222 can rotate while maintaining its center of rotation.

A universal joint 1224 may be disposed at one end of the shaft 1222. The universal joint 1224 can transmit rotational force for two configurations where the rotation axes are parallel and non-parallel. The universal joint 1224 may be connected to one end of the connecting rod 1225, and the other end of the connecting rod 1225 may be connected to another universal joint 1224. The driving unit 121 may be implemented as a motor.

The shaft 1222 can be rotated by the driving unit 121, and the rotational speed of the shaft 1222 can be sensed by the rotation detection unit 1222-1.

The rotation detection unit 1222-1 may include a rotation detection housing 1222-1a, a magnetic body 1222-1b, and a rotation detection sensor 1222-1c.

The rotation sensing housing 1222-1a may be disposed adjacent to the bearing 1223 and may be disposed between the bearing 1223 and the driving unit 121. A shaft 1222, a magnetic body 1222-1b, and a rotation sensor 1222-1c may be disposed inside the rotation detection housing 1222-1a.

The magnetic material 1222-1b may be disposed on the shaft 1222 and rotate according to the rotation of the shaft 1222. The rotation detection sensor 1222-1c is arranged to be connected to the rotation detection housing 1222-1a and can detect changes in magnetic force of the magnetic material 1222-1b.

In this way, the rotation speed of the shaft 1222 can be measured by the rotation detection unit 1222-1, and the flow rate of the fluid 126 discharged from the discharge unit 120 can be measured.

A sealing portion 1224-2 may be disposed on the universal joint 1224 disposed on the connecting rod 1225 connected to the shaft 1222. The sealing portion 1224-2 is disposed between the universal joint 1224 and the discharge housing 112 to suppress vibration of the universal joint 1224. A sealing hole may be formed in the sealing portion 1224-2 to communicate one side of the universal joint 1224 with the other side. Air on one side and the other side of the universal joint 1224 may communicate through the sealing hole.

A gas communication unit 1224-1 may be formed in the discharge housing 112. External air may flow into the discharge unit housing 112 through the gas communication unit 1224-1. Gas flowing in through the gas communication unit 1224-1 passes through the sealing hole of the sealing unit 1224-2, through the cavity 125 of the discharge unit 120, and through the nozzle 1226 or valve 1228. may be discharged. As the gas is discharged through the gas communication unit 1224-1, through the cavity 125, and through the nozzle 1226 or valve 1228, the fluid remaining inside the discharge unit 120 can be removed. Through this configuration, the inside of the dispenser can be kept clean. The gas communication unit 1224-1 may be implemented as a hole through which gas communicates.

Alternatively, gas generated from the pores of the fluid 126 may be discharged to the outside of the dispenser 10 through the gas communication unit 1224-1.

The universal joint 1224 connected to the other end of the connecting rod 1225 may be connected to the rotor 124. In this way, as the shaft 1222, the two universal joints 1224, the connecting rod 1225, and the rotor 124 are connected, even if the rotation axes of the rotor 124 and the shaft 1222 are different, the rotor 124 It may rotate according to the rotation of the shaft 1222. The connecting rod 1225 may be arranged such that its rotation axis is parallel or not parallel to the shaft 1222.

The rotor 124 can rotate with respect to the stator 123 by the universal joint 1224 connected to the other end of the connecting rod 1225. The shape of the rotor 124 may be similar to the shape of a spirally formed cylinder. The shape of the stator 123 may be implemented as having a pitch twice as long as the pitch length of the rotor 124. In this way, a pump that moves fluid by rotating the rotor 124 implemented in a spiral shape with respect to the stator 123 can be defined as a monopump.

A fluid inlet 1221 may be disposed in at least a portion of the discharge pipe 122. The fluid inlet 1221 is connected to the supply line 1111 so that fluid can flow into the dispenser 10 from outside the dispenser 10. The fluid inlet 1221 may be implemented as a hole through which fluid flows.

The stator 123 may be made of an elastic body, and a cavity 125 with high sealing force may be formed between the stator 123 and the rotor 124. As the rotor 124 rotates, the fluid disposed in the cavity 125 between the stator 123 and the rotor 124 may move. The direction of fluid movement may vary depending on the rotation direction of the rotor 124. According to one embodiment, when the rotor 124 rotates clockwise, the fluid may move in the direction opposite to the direction in which the driving unit 121 is disposed, and when the rotor 124 rotates counterclockwise, the fluid may move toward the direction in which the driving unit 121 is disposed. You can move in any direction. According to another embodiment, when the rotor 124 rotates clockwise, the fluid may move toward the direction in which the driving unit 121 is disposed, and when the rotor 124 rotates counterclockwise, the fluid may move in the opposite direction in which the driving unit 121 is disposed. You can move in any direction. A description of the movement of fluid will be described later with reference to FIGS. 5 and 6.

A vibrating unit 123-1 may be disposed in the discharge housing 112. The vibration unit 123-1 may generate vibration and transmit the vibration to the discharge unit housing 112. As vibration is transmitted to the discharge unit housing 112, the gap formed in the fluid 126 accommodated in the discharge unit 120 may be removed, or the gap may move toward the cleaning liquid inlet 1221-1. Accordingly, as voids are removed from the fluid 126, the quality of the fluid 126 discharged from the dispenser 10 can be prevented from deteriorating.

The vibration unit 123-1 may include a vibration connection unit 123-12 connected to the discharge unit housing 112 and a vibration drive unit 123-11 connected to the vibration connection unit 123-12.

The vibration driving unit 123-11 may generate vibration, and the vibration generated from the vibration driving unit 123-11 may be transmitted to the discharge housing 112 through the vibration connection unit 123-12. Accordingly, the voids inside the fluid 126 can be removed, and the quality of the fluid 126 discharged from the dispenser 10 can be prevented from deteriorating.

A nozzle 1226 may be disposed at one end of the rotor 124 and one end of the stator 123. The fluid moved through the rotation of the rotor 124 may be discharged to the outside of the dispenser 10 through the nozzle 1226. A shape adjusting part 1227 may be disposed in the opening of the nozzle 1226. A description of the shape adjustment unit 1227 will be described later along with the description of FIG. 4.

A cleaning fluid inlet 1221-1 may be disposed in the discharge housing 112 adjacent to the fluid inlet 1221. The fluid flowing into the dispenser 10 from the fluid inlet 1221 may have a high viscosity, and if it is maintained inside the dispenser 10 for a long time, some of it may harden. In this way, the hardened fluid may cause defects in the function of the dispenser 10. To remove the hardened fluid, the dispenser 10 can be disassembled, but this may consume a lot of time and money. The cleaning fluid inlet 1221-1 allows cleaning fluid capable of removing the hardened fluid to flow in, and moves along the path through which the fluid passes through the fluid inlet 1221 to remove the hardened fluid. It may be discharged through the nozzle 1226.

A heating wire 1229 may be disposed inside or outside the stator 123. The heating wire 1229 generates heat and can prevent the fluid disposed inside the stator 123 from hardening. As the heating wire 1229 prevents hardening of the fluid, the durability of the dispenser 10 can be improved.

A valve 1228 in communication may be disposed on at least a portion of the nozzle 1226. The valve 1228 can be opened and closed, and when the valve 1228 is open, fluid can be discharged out of the dispenser 10 through the valve 1228, and when the valve 1228 is closed, the fluid can be discharged through the valve 1228. It may not be discharged out of the dispenser (10). Valve 1228 may be used for a variety of purposes. According to one embodiment, the fluid or cleaning liquid flowing into the fluid inlet 1221 and/or the cleaning liquid inlet 1221-1 may be discharged. Alternatively, it may be used to discharge impurities placed inside the cavity 125 when operating the dispenser 10 that has not been operated for a certain period of time. Accordingly, the quality of the fluid discharged from the dispenser 10 can be prevented from decreasing.

The shape control shaft 1227b may be connected to the discharge housing 112, and the shape control shaft 1227b may be connected to the shape control plate 1227a. The shape control plate 1227a can rotate around the shape control axis 1227b. A shape control hole 1227c may be formed in the shape control plate 1227a.

The shape of the shape control hole 1227c may vary. According to one embodiment, the shape of the shape adjustment hole 1227c may include a circle, square, triangle, squares arranged side by side, inequality sign, etc. When the fluid 126 is discharged from the dispenser 10 through the shape control hole 1227c, the fluid 126 may be discharged corresponding to the shape of the shape control hole 1227c. As the fluid 126 is discharged according to the shape of the shape control hole 1227c, the constructability of the dispenser 10 for discharging the fluid 126 can be improved.
