The dental cleaning head 300 used in cooperation with the main dental cleaning unit 100 has at least two types of structures so as to perform different functions. For example, the prophy head 300 is a tooth-rinsing nozzle, a toothbrush, or a composite structure of a nozzle and a toothbrush, etc., as described further below. The vibration source 110 and the water pumping assembly 130 are arranged in the main tooth cleaning machine 100, and according to the type of the tooth cleaning head 300 mounted on the main tooth cleaning machine 100, a user can control the vibration source 110 to work, or control the water pumping assembly 130 to work, or control the vibration source 110 and the water pumping assembly 130 to work simultaneously through the main tooth cleaning machine 100, so as to obtain different cleaning functions.

Referring to fig. 2, the main dental unit 100 includes a housing 120, a mounting hole 121 for mounting a dental head 300 is formed on the housing 120, and a vibration source 110 and a water pumping assembly 130 are disposed in the housing 120. An adapter 150 is further arranged in the shell 120, the adapter 150 is connected with the vibration source 110 and connected with the water pumping assembly 130, and the dental scaler 300 is detachably connected with the adapter 150 through the mounting hole 121. The vibration generated from the vibration source 110 may be transmitted to the dental cleaning head 300 mounted to the housing 130 through the adaptor 150, and the water pumped by the water pumping assembly 130 may be delivered to the dental cleaning head 300 through the adaptor 150.

Referring to fig. 2, the adaptor 150 has a circumferential sidewall 151 and a bottom 153, the bottom 153 is disposed at an end of the circumferential sidewall 151 to define a receiving cavity 155, such that the adaptor 150 has opposite open and closed ends. The open end of the adaptor 150 faces the mounting hole 121 of the housing 120 and communicates with the mounting hole 121. As shown in FIG. 1, when the dental cleaning head 300 is mounted to the housing 120 through the mounting hole 121, one end of the dental cleaning head 300 is inserted into the receiving cavity 155. A side of the bottom 153 facing away from the receiving cavity 155 is provided with a connecting shaft 152. The output shaft of the vibration source 110 is disposed at a position corresponding to the connecting shaft 152, and is connected to the connecting shaft 152. When the vibration source 110 is driven to vibrate, the adaptor 150 connected to the output shaft of the vibration source 110 vibrates therewith and transmits the vibration to the dentifrice head 300 connected to the adaptor 150.

The adaptor 150 is made of alloy or metal to reduce vibration loss during vibration transmission and prevent corrosion.

The shaft diameter of the connecting shaft 152 is the same as the shaft diameter of the output shaft of the vibration source 110. Referring to fig. 2, a coupling hole 123 is formed in the housing 120 at a position corresponding to the output shaft of the vibration source 110 and the connecting shaft 152, the output shaft of the vibration source 110 extends into the coupling hole 123 from an opening at one end of the coupling hole 123, and the connecting shaft 152 extends into the coupling hole 123 from an opening at the other end of the coupling hole 123 to be coupled to the output shaft of the vibration source 110. The peripheral side surface of the housing 120, which is used for enclosing the engagement hole 123, plays a role in restraining the output shaft and the connecting shaft 152, so as to prevent the connecting shaft 152 and the output shaft of the vibration source 110, which are connected relatively, from shaking, and improve the vibration transmission efficiency between the vibration source 110 and the adaptor 150.

Referring to fig. 2, the adaptor 150 is provided with a through hole 154. In this embodiment, the through hole 154 is provided on the circumferential side wall 151 of the adaptor 150 in communication with the housing chamber 155, making it possible to reduce the radial dimension of the adaptor 150 compared to providing the through hole 154 on the bottom 153. The center line of the through hole 154 is perpendicular to the axis of the connecting shaft 152. The position of the inside of the housing 120 corresponds to the through hole 154, the water pumping assembly 130 is provided with a pipe joint 132, one end of the pipe joint 132 is connected with the water pumping assembly 130, and the other end of the pipe joint 132 penetrates through the through hole 154 and is communicated with the accommodating cavity 155 to form a water flow passage. The water flow delivered by the water pumping assembly 130 enters the adaptor 150 from the adapter 132 and enters the prophy head 300 connected to the adaptor 150 and is ejected from the prophy head 300.

A sealing member such as a packing or the like is provided at a position where the nipple 132 is engaged with the through-hole 154 to prevent water from leaking out from a connection position of the nipple 132 and the adaptor 150.

Referring to fig. 2, the vibration source 110 and the water pumping assembly 130 are disposed in the housing 120 and are connected to a main control circuit board disposed in the housing 120. The vibration source 110 is a sonic vibration motor having an output shaft that directly interfaces with the coupling shaft 152. The water pumping assembly 130 comprises a piston pump 135, wherein the piston pump 135 comprises a pump body 136 and a piston rod 137 sliding relative to the pump body; the output end of the pump body 136 is connected with the input end of the pipe joint 132.

Referring to fig. 2, the water pumping assembly 130 further includes a driving motor 133 and a power gear 134, the driving motor 133 is connected to a main control circuit board disposed in the housing 120, a gear-shaped output shaft of the driving motor 133 is engaged with the power gear 134, one end of a piston rod 137 is connected to a fixed shaft of the power gear 134, and the other end of the piston rod 137 is located in the pump body 136. When the main control circuit board controls the driving motor 133 to start, the output shaft of the driving motor 133 drives the power gear 134 to rotate so as to drive the piston rod 137 to slide back and forth relative to the pump body 136, so that the air pressure inside the pump body 136 changes, water flow is conveyed from the water inlet end of the pump body 136 to the water outlet end and enters the pipe joint 132, and finally the water flow is ejected from the dental cleaning head 300 through the adapter 150.

Because one side of the adapter 150 is connected with the pipe joint 132, the connecting shaft 152 on the adapter 150 is connected with the output shaft of the vibration source 110, and the vibration source 110 and the water pumping assembly 130 are both connected with the main control circuit board arranged in the shell 120. When the dental head 300 requiring only a vibration function is connected, the vibration source 110 may be separately activated under the control of the main control circuit board to transmit vibration to the adaptor 150, and finally, the dental head 300 is vibrated. Likewise, when the prophy head 300, which requires only flushing power, is attached, the water pumping assembly 130, under the control of the main control circuit board, can be activated alone to deliver a flow of water to the adaptor 150 and ultimately out of the prophy head 300. When the tooth cleaning head 300 having both water supply and vibration is connected, the vibration source 110 and the water pumping unit 130 can be simultaneously activated, thereby achieving the vibration of the tooth cleaning head 300 and the water supply function.

Referring to FIG. 3, the prophy angle 100 further includes a locking mechanism 160. In order to clearly view the locking mechanism 160 and the state of the locking mechanism 160 engaged with the prophy head 300, some elements of the prophy main body 100 are omitted from FIG. 3. A locking mechanism 160 is located at the end of the housing 120 where the mounting hole 121 is located to provide an escape path for the prophy head 300 to be mounted to the housing 120 or to be detached from the housing 120. The locking mechanism 160 includes a pressing unit 170 and a clutch unit 190, the clutch unit 190 is located in the housing 120, and the pressing unit 170 is located above the clutch unit 190 and is partially inserted in the housing 120. The pressing unit 170 can move downwards relative to the clutch unit 190 under the action of external force to change the position of the clutch unit 190; after the external force is removed, the pressing unit 170 returns to the home position, and the clutch unit 190 returns to the home position.

Referring to fig. 3, the pressing unit 170 includes a pressing cover 161 and a vertical elastic member 163. A hollow carrier 122 is formed in the housing 120 at a position corresponding to the vertical elastic element 163, and in the present embodiment, the carrier 122 and the housing 120 are integrally formed. One end of the vertical elastic element 163 is located in the bearing member 122, and the other end is exposed out of the bearing member 122 and abuts against the pressing cover 161. One end of the pressing cover 161 close to the clutch unit 190 is inserted into the housing 120 and can reciprocate with respect to the housing 120. A wedge 169 having an inclined surface is provided on a side of the pressing cover 161 facing the clutch unit 190. The clutch unit 190 is provided with a sloped protrusion 191 at a position corresponding to the wedge 169 to slide in surface contact with the wedge 169.

Referring to fig. 3, the clutch unit 190 includes a horizontal elastic member 167, and a first latch 162 and a second latch 164 oppositely disposed left and right. The clearance area between the first and second detents 162, 164 communicates up and down with the receiving cavity 155 of the adaptor 150. In this embodiment, the first and second grips 162, 164 are identical in shape. A beveled protrusion 191 is formed on the first catch 162 at a location opposite the wedge 169 and, similarly, a beveled protrusion 191 is formed on the second catch 164 at a location opposite the wedge 169. Horizontal spring assembly 167 includes a first spring member 166 and a second spring member 168. The first elastic member 166 abuts the housing 120 and the first latch 162 at both ends thereof, and the second elastic member 168 abuts the housing 120 and the second latch 164 at both ends thereof.

The locking mechanism 160 operates on the following principle: when an external force is applied to the pressing cover 161, the vertical elastic member 163 is compressed and deformed, the pressing cover 161 moves downward, the inclined surface of the wedge 169 comes into contact with the inclined surfaces of the first locking piece 162 and the second locking piece 164, and the first locking piece 162 is urged to compress and deform the first elastic member 166, so that the first locking piece 162 moves leftward and similarly the second locking piece 164 moves rightward. At this time, the first and second stoppers 162 and 164 are away from each other, and one end of the dentifrice head 300 can be fitted into the receiving cavity 155 of the adaptor 150. When the external force is removed, the vertical elastic member 163 is deformed again to push the pressing cover 161 to move upward, the inclined surface of the wedge 169 is gradually separated from the inclined surfaces of the first and second stoppers 162 and 164, the first elastic member 166 is deformed again to push the first stopper 162 to move backward, and the second stopper 164 is also moved backward by the elastic restoring force of the second elastic member 168. The first and second stoppers 162 and 164 approach each other to hold the mouthpiece 300.

As shown in fig. 4, the first locking piece 162 and the second locking piece 164 have arc-like ends at both ends thereof, and are engaged with the peripheral side surface of the dental head 300 attached to the housing 120. In addition, the teeth cleaning head 300 is provided with a locking groove 301 in a circumferential direction at a position facing the first locking member 162 and the second locking member 164, and when the first locking member 162 and the second locking member 164 are engaged with the locking groove 301, the teeth cleaning head 300 can be prevented from being detached from the adaptor 150.

A prophy head 300 for use with a prophy master 100 as described above has at least two types of configurations to perform different cleaning functions in cooperation with the prophy master 100. One end of the tooth cleaning head 300, which is used for being matched with the tooth cleaning main unit 100, is provided with a clamping groove 301 so as to be clamped with the clutch unit 190 in the tooth cleaning main unit 100.
