[ Detailed description ] of the invention
The technical solutions of the embodiments of the invention are explained and illustrated below with reference to the drawings of the embodiments of the invention, but the embodiments described below are only preferred embodiments of the invention, not all. Based on the examples in the embodiments, those skilled in the art can obtain other examples without making any inventive effort, which fall within the scope of the invention.
In the following description, directional or positional relationships such as the terms "inner", "outer", "upper", "lower", "left", "right", etc., are presented for convenience in describing the embodiments and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the invention.
As shown in fig. 1 to 8, a plunger type pump body comprises a driving source 1, an outer pump body 2 and an inner pump body 3 arranged in the outer pump body 2, wherein a hollow inner cavity 300 is arranged in the inner pump body 3, the hollow inner cavity 300 is provided with a plunger 31, the plunger type pump body further comprises an eccentric member 4 for providing eccentric guidance for the plunger 31, the plunger 31 reciprocates in the hollow inner cavity 300, the eccentric member 4 is arranged to rotate relative to the outer pump body 2, the driving source 1 directly drives the eccentric member 4, and then the plunger 31 is driven to reciprocate by the eccentric member 4.
In this embodiment, the inner pump body 3 and the outer pump body 2 are rotatably disposed relatively, the eccentric member 4 and the outer pump body 2 are fixed relatively, the driving source 1 is connected with the inner pump body 3 and drives the inner pump body 3 to rotate, and the inner pump body 3 drives the plunger 31 to reciprocate in the hollow inner cavity 300 around the eccentric member 4 while rotating.
With this structural improvement, the driving mode of the plunger 31 is correspondingly changed, the driving source 1 directly drives the inner pump body 3 to rotate, instead of driving the eccentric member 4 to rotate, in this embodiment, the eccentric member 4 is kept stationary, and the plunger 31 also follows rotation by means of the inner pump body 3 when rotating, and because the plunger 31 is connected with the eccentric member 4, eccentric motion is generated relative to the eccentric member 4, and the final motion mode is: the plunger 31 performs a reciprocating motion with respect to the inner pump body 3 while performing a self-rotation.
In the motion mode, the plunger 31 is driven by the acting force of the hollow inner cavity 300 of the inner pump body 3, and obviously, in the driving mode, the contact area between the hollow inner cavity 300 and the plunger 31 is larger than that between the plunger 31 and the eccentric member 4, so that the stress is more uniform, the driving force of the inner pump body 3 to the plunger 31 is dispersed, the stress concentration area is reduced, and the abrasion degree is reduced;
In addition, in this movement mode, the plunger 31 rotates while reciprocating, so that the vibration generated by the eccentric force of the plunger 31 is mostly counteracted by the rotation of the plunger 31, and the vibration feeling of the plunger 31 can be obviously reduced.
The specific preferred structure of this embodiment is as follows:
in this embodiment, the plunger 31 is disposed in the hollow cavity 300 to divide the hollow cavity 300 into two spaces, one end of the plunger 31 and the hollow cavity 300 form a first cavity 300a, the other end of the plunger 31 and the hollow cavity 300 form a second cavity 300b, wherein the first cavity 300a is communicated with a first water inlet 301 and a first water outlet 302, the first water inlet 301 is communicated with the bottom of the first cavity 300a, and the first water inlet 301 is communicated with the top of the first cavity 300a with reference to the orientation of fig. 1 to 5.
When the plunger 31 reciprocates, the first inner cavity 300a can realize negative pressure and high pressure replacement, the first water outlet 302 is closed when the first inner cavity 300a is negative pressure, the first inner cavity 300a sucks water through the first water inlet 301, the first water inlet 301 is closed when the first inner cavity 300a is high pressure, the first inner cavity 300a discharges water through the first water outlet 302, and various forms such as a check valve are adopted to realize control when the first water outlet 302 is closed and opened and the first water inlet 301 is closed and opened.
In this embodiment, the internal structure is improved to realize the function of replacing the control of the one-way valve, and the specific steps are as follows: the water outlet cover plate 5 and the water inlet cover plate 6 are respectively arranged between the two axial ends of the inner pump body 3 and the outer pump body 2, the water outlet cover plate 5 is provided with a water outlet channel 50 which is communicated with the first water outlet hole 302, the water inlet cover plate 6 is provided with a water inlet channel 60 which is communicated with the first water inlet hole, and in the rotation process of the inner pump body 3, only one of the water inlet channel 60 and the first water inlet hole 301 and the water outlet channel 50 and the first water outlet hole 302 is kept in a communicated state.
In other words, the water outlet cover plate 5 and the water inlet cover plate 6 are fixed relative to the outer pump body 2, the inner pump body 3 rotates relative to the water outlet cover plate 5 and the water inlet cover plate 6 in the rotating process, when the water outlet channel 50 on the water outlet cover plate 5 is not communicated with the first water outlet hole 302, the first water outlet hole 302 is closed, and when the water outlet channel 50 is communicated with the first water outlet hole 302, the first water outlet hole 302 is opened to discharge water; similarly, when the water inlet channel 60 on the water inlet cover plate 6 is not communicated with the first water inlet 301, the first water inlet 301 is closed, and when the water inlet channel 60 on the water inlet cover plate 6 is communicated with the first water inlet 301, the first water inlet 301 is opened, so that water inlet can be realized. Therefore, through the structure of this embodiment, only the circumferential positions of the water inlet cover plate 6 and the water outlet cover plate 5 need to be reasonably set, and the opening and closing of the first water inlet hole 301 and the first water outlet hole 302 can be realized by using the water inlet cover plate 6 and the water outlet cover plate 5. Therefore, the check valve is replaced by a pure mechanical structure, the structure of the check valve is omitted, a controller for controlling the check valve is omitted, and the reliability is better.
With this structure, water inlet and water outlet exchange can be realized, that is, if the driving source 1 is driven in the reverse direction, the end of the original water outlet becomes water inlet, and the end of the original water inlet becomes water outlet, only the direction of the driving source 1 needs to be changed, and if the one-way valve is adopted, the water outlet direction of the one-way valve is single, so that water inlet and water outlet exchange cannot be realized.
In addition, in this embodiment, in order to improve the water inlet and outlet efficiency, in this embodiment, the second inner cavity 300b is communicated with the second water inlet 303 and the second water outlet 304, which is equivalent to providing another group of water inlet and outlet combinations in the second inner cavity 300b, and just like the water inlet and outlet combinations of the first group, only one of them is kept in a communication state between the water inlet channel 60 and the second water inlet 303, and between the water outlet channel 50 and the second water outlet 304. After the two groups of water inlet and water outlet are combined, when the plunger 31 reciprocates once, the two water inlet and water outlet are realized, and obviously, the water inlet and water outlet efficiency is higher.
In addition, for the sake of optimizing design, the water inlet channel 60 and the water outlet channel 50 include arc-shaped channels, specifically include arc-shaped channels and flow holes communicating with the arc-shaped channels, and for convenience of description, the water inlet channel 60 includes a lower arc-shaped channel 601 and a lower flow hole 602, and the water outlet channel 50 includes an upper arc-shaped channel 501 and an upper flow hole 502. When the first water inlet 301 is in communication with the water inlet 60, the second water outlet 304 is in communication with the water outlet 50, i.e. when the first inner cavity 300a is flowing into the water inlet 301 through the first water inlet 301, the second inner cavity 300b is flowing out of the water outlet 304 through the second water outlet 304, as shown in fig. 6, so that the high pressure of the second inner cavity 300b is perfectly and smoothly released from the second water outlet 304, the resistance of the second inner cavity 300b to the plunger 31 is smaller, and the resistance of the reciprocating movement of the plunger 31 is smaller.
Similarly, for the second inner cavity 300b, when the second water inlet 303 is in communication with the water inlet channel 60, the first water outlet 302 is in communication with the water outlet channel 50. When the second inner cavity 300b is fed through the second water inlet 303, the first inner cavity 300a is discharging water through the first water outlet 302, as shown in fig. 7, so that the high pressure generated in the first inner cavity 300a is perfectly released from the first water outlet 302, and the resistance of the first inner cavity 300a to the plunger 31 is smaller. In combination, referring to fig. 4, the entire plunger 31 experiences little resistance during the reciprocation, whether it is moving to the left or right.
In addition, in order to ensure that the water inlet and the water outlet are isolated from each other, the inner pump body 3 has a closed position in the rotation process, when the inner pump body 3 is in the closed position, the first water inlet 301, the second water inlet 303 and the water inlet channel 60 are all kept disconnected, and the first water outlet 302, the second water outlet 304 and the water outlet channel 50 are all kept disconnected. The water in the water inlet channel 50 and the water outlet channel 60 are always isolated from each other in a state that the water is not communicated. In addition, such a closed position state has an additional beneficial effect, because in the closed position state, the first inner cavity 300a and the second inner cavity 300b of the inner pump body 3 are both in a closed state, which is equivalent to that when the inner pump body 3 rotates for one circle, the first inner cavity 300a and the second inner cavity 300b in the inner pump body 3 are not always in a state of being communicated with the outside, and an instant closed state exists, so that a certain pressure state can be ensured in the first inner cavity 300a and the second inner cavity 300b permanently, so that water is absorbed or discharged conveniently. Referring to fig. 4 or 8 specifically, the arcuate channel on the water outlet cover 5 is an upper arcuate channel 501, the arcuate channel on the water inlet cover 6 is a lower arcuate channel 601, when the inner pump body 3 is in the closed position, the head and tail of the upper arcuate channel 501 and the lower arcuate channel 601 are not connected into a perfect circle, a gap is cut off in the middle, and the first water inlet 301, the second water inlet 303, the first water outlet 302 and the second water outlet 304 are just in the gap, i.e. in this state, neither the first water inlet 301 nor the second water inlet 303 is communicated with the water inlet 60, nor the first water outlet 302 nor the second water outlet 304 is communicated with the water outlet 50.
For other parts, the outer pump body 2 of this embodiment includes a main casing 22, an upper casing 21 and a lower casing 23, the inner pump body 3 is rotatably disposed in the main casing 22, a water outlet cavity 210 is disposed in the upper casing 21, a water inlet cavity 230 is disposed in the lower casing 23, the eccentric member 4 includes a base column 41 and an eccentric column 42, the base column 41 is fixed on the upper casing 21 or the lower casing 23, for reference to the drawing of this embodiment, the base column 41 is fixed on the upper casing 21, the eccentric column 42 extends into the hollow cavity 300, a groove is disposed in the middle of the plunger 31, the groove is matched with the eccentric column 42, and for reducing wear, a sliding sleeve or a bearing is sleeved on the eccentric column 42.
In addition, for sealing performance, in this embodiment, sealing rings are provided at a plurality of positions, for example, between the water inlet cover plate 6 and the main casing 22, between the water outlet cover plate 5 and the main casing 22, between the upper casing 21 and the main casing 22, between the lower casing 23 and the main casing 22, between the rotating shaft 33 and the lower casing 23, and between the eccentric member 4 and the upper casing 21, so as to enhance sealing effect.
In this embodiment, the driving source 1 is fixedly connected to the lower casing 23, a through hole 231 is formed in the lower casing 23, a rotating shaft 33 is inserted into the through hole 231, the rotating shaft 33 is used for driving the inner pump body 3 and the driving source 1, and for the rotating shaft 33, it is preferable that the structure is integrated with the inner pump body 3 in this embodiment, however, in other embodiments, the rotating shaft 33 may be an output shaft on the driving source 1, and the output shaft extends into the through hole 231 from the bottom of the bottom casing and is connected with the inner pump body 3.
