FIG. 2 is a sectional view (2) of a piston water pump applied to a tooth flushing device in embodiment 1 of the utility model.
Detailed Description
As shown in figures 1 and 2, the piston water pump applied to the tooth flusher is not provided with a piston and a pump body which do rapid reciprocating motion, and the three-way pump body 100 is isolated into a water suction cavity 103 and a piston cavity 106 by the elastic rubber plunger 107, so that water in the water suction cavity 103 is effectively prevented from entering the interior of the tooth flusher through the piston cavity 106 to cause damage to a circuit board of the tooth flusher due to water inlet.
As shown in fig. 1 and fig. 2, the piston water pump applied to the tooth flusher of the present embodiment includes a three-way pump body 100 having a water inlet 101, a water outlet 102 and a water suction cavity 103, wherein the water inlet 101 and the water outlet 102 are respectively communicated with the water suction cavity 103 through a water inlet valve 104 and a water outlet valve 105; water enters the suction chamber 103 from the water inlet 101 and is ejected from the water outlet 102 under pressure. In this embodiment, the plunger comprises an elastic rubber plunger 107 for partitioning the three-way pump body 100 into a water suction cavity 103 and a piston cavity 106, a push-pull rod 200 connected to the center of the elastic rubber plunger 107, and a transmission mechanism 300 for driving the push-pull rod 200 to drive the center of the elastic rubber plunger 107 to move back and forth so as to change the volume of the water suction cavity 103. When the elastic rubber plunger 107 expands outwards, the volume of the water suction cavity 103 increases, the pressure in the water suction cavity 103 decreases, water is sucked into the water suction cavity 103 from the water inlet 101 under the action of atmospheric pressure, a water inlet valve 104 is arranged in the water inlet 101 and is an intentional valve, and when the pressure in the water suction cavity 103 is lower than the atmospheric pressure outside, the water inlet valve 104 is opened under the action of atmospheric pressure, the water outlet valve 105 is closed, and water enters the water suction cavity from the water inlet valve 104. When the push-pull rod 200 drives the elastic rubber plunger 107 to extrude towards the water suction cavity 103, the water suction cavity 103 is reduced in volume, the pressure of water in the water suction cavity is increased to be larger than the atmospheric pressure, at the moment, the water inlet valve 104 is closed, the water outlet valve 105 is opened, water compressed in the water suction cavity 103 is sprayed out from the water outlet 102, and the water pump can quickly spray water outwards by quickly pushing and pulling the push-pull rod 200.
In this embodiment, the transmission mechanism 300 for driving the push-pull rod 200 to reciprocate includes a small bevel gear 302, which is provided on an output shaft of the motor 301, a large bevel gear 303 engaged with the small bevel gear 302, and an eccentric shaft 304 provided on the large bevel gear 303, the eccentric shaft 304 being connected to one end of the push-pull rod 200. In this embodiment, the motor drives the large bevel gear 303 to rotate, the small bevel gear 302 is engaged with the large bevel gear 303 to realize the conversion of the rotation direction, the small bevel gear 302 and the large bevel gear 303 are both located in a vertical direction, and the large bevel gear 303 is provided with an eccentric shaft 304 to realize the reciprocating motion of the rotation direction to the vertical direction, so as to drive the push-pull rod 200 to reciprocate.
In this embodiment, the push-pull rod 200 is provided with a sliding groove 201 movably connected with the eccentric shaft 304, so that the sliding groove 201 on the push-pull rod 200 blocks the bevel gear 303, and the push-pull rod 200 can only move back and forth but cannot swing left and right.
The push-pull rod 200 is connected with the elastic rubber plunger 107 at the center by a rubber plunger 108 special for a water pump. The motor drives the small bevel gear to drive the large bevel gear, the eccentric shaft on the large bevel gear 303 drives the push-pull rod to move back and forth, and the special rubber plunger for the push-pull rod push-pull water pump moves back and forth, so that water is sucked and drained.
In this embodiment, the periphery of the elastic rubber plunger 107 is sealed on the inner wall of the three-way pump body 100 by a pressing sleeve 109.
Therefore, the periphery of the elastic rubber plunger 107 is sealed on the inner wall of the three-way pump body 100 by the pressing sleeve 109, and the piston cannot enter the tooth flushing device main machine due to water leakage at the edge of the piston.
