Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Referring to fig. 1 to 7, an adjustable injection pump according to an embodiment of the present invention is disposed in a water tank (not shown), and includes a nozzle 10, a nozzle 20, a baffle 30, and a buoyancy mechanism 40.
The nozzle 10 is connected to a pressure water source, which may be water from a municipal water supply or water from a water pump, as long as water with sufficient pressure can be provided, and the specific value of the minimum water pressure is different according to the size and relative position of the nozzle 10 and the nozzle 20.
The nozzle 20 has an inlet end 21, an outlet end 22 and a water spray channel 23 communicating the inlet end 21 and the outlet end 22, a through-flow gap 24 opening into the inner cavity of the tank is provided between the inlet end 21 and the nozzle 10, and the cross-sectional flow area of the nozzle 10 is smaller than that of the inlet end 21. When the nozzle 10 injects water under pressure against the inlet end 21 of the lance 20, the water in the water reservoir can enter the water injection channel 23 through the through-flow gap 24 due to the venturi effect and eventually be ejected from the outlet end 22 together with the water injected into the water injection channel 23 by the nozzle 10.
The baffle 30 is rotatably provided in the spout 20 to open or close the water spray passage 23.
The buoyancy mechanism 40 includes a float 41 and an adjusting member 42, the float 41 is position-adjustably mounted on the adjusting member 42 such that the height of the float 41 in the floating position is adjustable, and the float 41 controls the flapper 30 to open or close the water spray passage 23 according to the water level variation of the water tank.
In this embodiment, the adjusting member 42 is a rigid screw structure. As shown in fig. 4, when the float 41 is floating, the adjusting member 42 drives the baffle 30 to open the water spraying channel 23, and when the nozzle 10 sprays pressurized water toward the inlet end 21 of the nozzle 20, the water flow in the tank cavity enters the water spraying channel 23 through the through-flow gap 24 under the action of venturi, and is sprayed out from the outlet end 22 of the water spraying channel 23 together with the water entering the water spraying channel 23 from the nozzle 10. As shown in fig. 5, when the float 41 is in the lowered position, the flap 30 is moved by the adjusting element 42 to close the water spray channel 23, and the water jet from the nozzle 10 towards the lance 20 is blocked by the flap 30 and flows into the interior of the tank through the flow gap 24. Of course, in other embodiments, for example, when the adjusting member 42 is a flexible chain structure, or when the floating barrel 41 is falling, the baffle 30 can close the water spraying channel 23 under the elastic force of the elastic member, the gravity of the counterweight, or the magnetic force of the magnetic member.
In this embodiment, the device further includes a swing link 50, a first end 51 of the swing link is connected to one end of the adjusting member 42, a second end 52 of the swing link is pivotally connected to the nozzle 20, a rotating end of the baffle 30 is connected to the second end 52 of the swing link, and when the swing link 50 is driven by the adjusting member 42 to rotate around the second end 52 of the swing link, the swing link 50 drives the baffle 30 to rotate around the rotating end of the baffle 30.
Specifically, the swing link 50 includes a first rod 53 and a second rod 54 arranged in parallel, and further includes a connecting rod 55 for connecting the first rod 53 and the second rod 54, first ends of the first rod 53 and the second rod 54 are both connected with one end of the adjusting member 42, a second end of the first rod 53 is pivotally connected with the nozzle 20, and a second end of the second rod 54 is rotatably linked and matched with a rotating end of the baffle 30.
In this embodiment, the rotating end of the baffle 30 is provided with a rotating shaft 31, the rotating shaft 31 extends out of the nozzle 20, the second end 541 of the second rod 54 is provided with a non-circular shaft hole 5411, the rotating shaft 31 is inserted into the shaft hole 5411, and the swing rod 50 is in rotational linkage fit with the rotating end of the baffle 30 through the fit between the rotating shaft 31 and the shaft hole 5411, so as to drive the baffle 30 to rotate.
In this embodiment, the adjusting member 42 is a screw 421, the bottom end of the screw 421 is connected to a pivot rod 422, and two ends of the pivot rod 422 are respectively pivoted to the first ends of the first rod 53 and the second rod 54. The float 41 is screwed on the screw 421 to adjust its position on the screw 421. Referring to fig. 6, the float 41 is shown at a lower position on the screw 421, and the float 41 falls down later as the water level of the tank falls, so that the baffle 30 closes the water spraying passage 23 later and the amount of water sprayed is larger. Fig. 7 is a schematic view of the upper position of the float 41 on the screw 421, in which the float 41 drops earlier as the water level of the tank drops, so that the shutter 30 closes the water spraying passage 23 earlier and the amount of water sprayed is less.
In this embodiment, the inner wall of the nozzle 20 is provided with a limiting step surface 25, and the baffle 30 closes the water spraying passage 23 when moving to abut against the step surface. Preferably, a sealing element is arranged between the baffle 30 and the limit step surface 25, and the sealing element of the embodiment adopts a sealing gasket 32 arranged on the baffle 30.
In this embodiment, one side of the nozzle 20 protrudes outward in the radial direction to form a receding cavity 26 in the inner cavity of the nozzle 20, the receding cavity 26 is located between the inlet end 21 of the nozzle 20 and the limiting step surface 25, the inlet end 21 of the nozzle 20 and the limiting step surface 25 correspond to each other in the axial direction of the nozzle 20, the receding cavity 26 is offset from the inlet end 21 of the nozzle 20 and the limiting step surface 25 in the axial direction, and the baffle 30 is located in the receding cavity 26 when the water spraying channel 23 is opened, so that the baffle 30 does not block water flow when the water spraying channel 23 sprays water, and the water spraying effect is better.
In this embodiment, the spray pump further comprises a base 60 having a water supply channel 61, the nozzle 10 is fixed on the base 60 and communicated with the water supply channel 61, and the inlet end 21 of the spray pipe 20 is connected with the base 60, so that the whole spray pump is of an integrated structure, and the installation of the spray pump is more convenient. Specifically, the base 60 is provided with a snap ring 62 surrounding the nozzle 10, the snap ring 62 is provided with a plurality of elastic buckles at intervals along the circumferential direction, and the inlet end 21 of the nozzle 20 is inserted into the snap ring 62 and then is clamped by the buckles, so that the nozzle 20 is connected with the base 60. The water supply channel 61 may be connected to a municipal tap water line or to an outlet water line of a water pump that can draw water from a tank in which the jet pump is installed or from another external tank.
Referring to fig. 8 and 9, in another embodiment of the present invention, the adjusting member 42 is a chain 423, and the float bucket 41 can be installed at different links of the chain 423, thereby adjusting different positions of the float bucket 41 on the chain 423. Fig. 8 is a schematic view of the lower position of the float 41 on the chain 423, in which the float 41 falls down later as the water level of the tank falls, so that the baffle 30 closes the water spraying passage 23 later and the amount of water sprayed is larger. Fig. 9 is a schematic view of the upper position of the float 41 on the chain 423, in which the float 41 falls earlier as the water level of the tank falls, so that the shutter 30 closes the water spraying passage 23 earlier and the amount of water sprayed is less. Because the chain is a flexible structure, when the floating barrel 41 falls down, the baffle 30 needs to close the water spraying channel 23 under the action of the elastic force of the elastic member, the gravity of the counterweight, or the magnetic force of the magnetic member.
The invention also provides a toilet flushing device (not shown) comprising a cistern, a flushing water circuit and any one of the above adjustable jet pumps, the adjustable jet pump being mounted in the cistern with the outlet end 22 of the nozzle 20 communicating with the flushing water circuit.
