The driving unit 1 is equipped with a pumping unit for forcibly feeding raw water.

The pumping portion is a pump for applying pressure to the fluid to be fed to the filter 3, and is composed of a motor 1a and an impeller 1b.

The filtering unit 3 is provided as the RO filter described above.

This is because the characteristics of a portable water purifier must utilize natural water of a river or a river, so that the filtering power of the filter should be maximized.

That is, the UF (Ultra Filteration) filter used for domestic water purifier has a pore size of 0.01 to 0.1 micron, but the pore of the RO filter used in the portable water purifier is 0.0001 to 0.001 micron, have.

The raw water that has been pumped by the filtering unit 3 is filtered while passing through the filtering unit 3, and the filtered raw water is discharged as drinking water through the discharge unit 2.

Such a portable water purifier can be used for a variety of purposes because it is portable and can be used as a drinking water source in a disaster area or an industrial site as described above.

However, the conventional portable water purifier described above has the following problems.

First, since the pumping operation is performed using the power source, there is a limited problem in the installation place.

That is, since it is limited to a place where the power source must be available for the operation of the pumping, there is a limit to the installation place as a portable water purifier.

Second, the pump of the impeller (1b) type constituting the pumping unit can not be used without power supply for operating the driving motor and the pump.

That is, in the case of the RO filter, as described above, the pore size is fine, and the purified water is maximized by the pressing force by the pumping force, but it is virtually impossible to manually press the water only by the force of the person without electricity.

That is, an impeller-type water purifier equipped with an RO filter can not be operated without electricity.

Hereinafter, a portable manual suction and pressurization pump assembly (hereinafter referred to as a 'suction pump assembly') according to a preferred embodiment of the present invention will be described with reference to FIGS. 2 to 6B.

2, the suction pump assembly includes a main gear 100, a driven shaft 200, a side housing 300, a piston 400, an intermediate housing 500, a diaphragm 600, An access plate 700, a valve 800, and a head cover 900. The head cover 900 is made of a metal plate.

The main gear 100 generates a rotational force by manual rotation of the handle H and serves to rotate the driven shaft 200. [

The main gear 100 is formed with a plurality of gears around its outer periphery and a shaft hole 110 is formed at the center of the main gear 100 so that the handle H can be detached.

That is, the main gear 100 is configured to rotate the handle H to generate the rotational force of the main gear 100 in a state where the user inserts the handle H into the shaft hole 110.

Next, the driven shaft 200 receives the rotational force of the main gear 100 and rotates the cam portion to be described later.

The driven shaft 200 is engaged with the main gear 100 and is composed of a driven gear 210 having a diameter smaller than the diameter of the main gear 100 and a shaft 220 coupled to the cam.

The main gear 100 and the driven shaft 200 are preferably installed inside the hard case 5 constituting the external appearance of the portable water purifier and are installed to be shielded by the installed box 120 for reasons of beauty and hygiene .

The installation box 120 is preferably made of a metal material and forms an internal space for installing the main gear 100 and the driven shaft 200.

At this time, a first coupling hole 121 corresponding to the case hole 5a of the hard case 5 is formed on one side of the installation case 120, A second engaging hole 122 through which the second engaging portion 220 passes is formed.

Next, the side housing 300 constitutes a part of the outer surface of the suction pump P, and is a portion which is tightly coupled to the other surface of the installation box 120. [

A through hole 310 is formed in the center of the side housing 300 to axially couple the shaft 220 of the slave shaft 200 protruding through the second engagement hole 122 of the installation body 120.

At this time, a bearing is preferably provided on the inner circumferential surface of the through hole 310 for smooth rotation of the slave shaft 200.

Next, the piston 400 serves to generate a pressure in the inside of the diaphragm 600, and includes a cam portion 410 and a press protrusion 420.

The cam portion 410 is eccentrically rotated by the rotational force of the driven shaft 200 to swing (linearly move) the pressing protrusion 420 and is in close contact with the inner surface of the side housing 300.

At this time, an eccentric hole 411 is formed in the cam portion 410, and a slave shaft 200 is coupled to the eccentric hole 411.

One side and the other side of the cam portion 410 are formed differently from each other.

That is, the cam portion 410 is inclined from one side to the other side.

At this time, since the inclined surface of the cam portion 410 is in close contact with the inner side surface of the side housing 300, the cam portion 410 swings based on the inner surface during rotation by the driven shaft 200. [

The pressing protrusion 420 is linearly moved (oscillated) by the swinging motion of the cam portion 410 and is rotatably coupled to the outer circumferential surface of the cam portion 410.

At this time, a bearing is provided between the cam portion 410 and the pressing protrusion 420 for smooth rotation of the cam portion 410 with respect to the pressing protrusion 420.

The pressing protrusions 420 are preferably formed in three positions as shown in FIG. 2, and are formed at three positions with respect to the cam portion 410, respectively.

Next, the diaphragm 600 generates a pressure by rectilinear motion of the pressing protrusion 420, and serves to suck and drain purified water.

The diaphragm 600 is coupled with the access plate 700 to form a suction channel and a drain channel of the purified water in the inner space formed between the diaphragm 600 and the access plate 700. By the rectilinear motion of the pressing projection 420 One surface of the diaphragm 600 reciprocates toward the entrance plate 700 to form a pressure in the internal space.

That is, when the pressure projection 420 presses and presses one surface of the diaphragm 600, a drain pressure (pressurization) is generated in the diaphragm, and when the pressure projection 420 releases the pressing force against the diaphragm 600, Self-stimulation).

At this time, the interlocking members 610 are respectively coupled to the portions corresponding to the pressing protrusions 420.

Since the number of the pressing protrusions 420 is three, the interlocking member 610 is also joined to three points of the diaphragm 600.

Particularly, the interlocking member 610 swings together with one side of the diaphragm 600 when the pressing protrusion 420 presses one side of the diaphragm 600, thereby maximizing the drain pressure.

Next, the access plate 700 is coupled to the diaphragm 600 to form a suction passage and a drain passage of the purified water.

The access plate 700 shields the interlocking member 610 coupled to the diaphragm 600 and forms an internal space between the diaphragm 600 and the suction flow path and the drain flow path.

At this time, the space where the interlocking member 610 is disposed is divided into three points on the inner surface of the access plate 700, and this space is referred to as a partition groove 710.

In each of the partition grooves 710, an absorption hole 711 is formed to communicate with the inside and the outside of the access plate 700.

The absorption hole 711 is an inner space formed by the inlet plate 700 and the diaphragm 600, and is a channel through which purified water is drawn.

On the other hand, a drain hole 712 for draining the water absorbed through the absorption hole 711 is formed at one side of the partition groove 710.

At this time, a drain hole 712 is also formed in each of the partition grooves 710, and a penetration portion of the drain hole 712 is formed at the center of the access plate 700.

At this time, a center groove 720 for disposing a drain valve, which will be described later, is formed at the front center of the access plate 700. The drain hole 712 penetrates the inside surface of the access plate 700 and the center groove 720 .

Next, the valve 800 functions to open and close the absorption hole 711 and the drain hole 712.

The valve 800 preferably opens and closes the absorption hole 711 and the drain hole 712 by the internal pressure of the diaphragm 600 generated by the swinging motion of the diaphragm 600 and is preferably made of soft rubber.

At this time, the valve for opening and closing the absorption hole 711 is called an absorption valve 810 and is disposed in each of the division grooves 710.

At this time, a buffer protrusion 811 protruding outside the access plate 700 is formed at one side of the absorption valve 810 through the access plate 700.

The buffer protrusion 811 functions to buffer the absorption valve 810 in the process of pressing the absorption valve 810 when the drainage pressure is generated by the fluctuation of the diaphragm 600.

The buffering protrusion 811 is preferably made of soft rubber for buffering the absorption valve 810.

The valve for opening and closing the drain hole 712 is called a drain valve 820 and the drain valve 820 is coupled to the center groove 720 formed at the center of the front plate of the entrance plate 700.

That is, the absorption valve 810 opens and closes the absorption hole 711 on the inner surface of the access plate 700, and the drain valve 820 opens and closes the drain hole 712 on the outer surface of the access plate 700.

Next, the head cover 900 forms a channel for discharging purified water filtered through the filter to the outside of the suction pump P through the inside of the suction pump P, and covers the inlet plate 700 Is coupled to the intermediate housing (500) and the side housing (300).

An inlet 910 for introducing purified water into the suction pump P is formed at one side of the head cover 900 and a discharge portion 920 for discharging purified water is formed at the other side of the head cover 900 .

The inner side of the head cover 900 is divided into three inflow spaces 911 corresponding to the absorption holes 711 formed in the access plate 700. In the inflow space 911, An insertion boss 911a into which the insertion hole 811 is inserted is formed.

At the center of the head cover 900, a drain space 921 partitioned from the inflow space 911 is formed.

The drainage space 921 corresponds to the center groove 720 of the access plate 700 and a sealing member S is interposed between the center groove 920 and the drainage space 921.

The drainage space 921 is formed with a conduit communicating with the discharge portion 920.

Hereinafter, the engagement and operation of the suction pump assembly having the above-described structure will be described.

A plurality of RO filters (not shown) are fixed to the other side of the hard case 5 in a fixed position on one side of the hard case 5 constituting the portable water purifier.

A main gear 100 and a driven gear 210 of a driven shaft 200 are engaged with each other in the installation case 120.

At this time, the shaft hole 110 of the main gear 100 is exposed through the first coupling hole 121 of the installation case 120 and the case hole 5a of the hard case 5, and the slave shaft 200 is installed And protrudes through the second engagement hole 122 of the housing 120.

In order to engage the suction pump P, the piston 400 is first brought into close contact with the inner surface of the side housing 300.

The through hole 310 of the side housing 300 corresponds to the eccentric hole 411 formed in the cam portion 410 of the piston 400. [

Next, the piston 400 is covered with the intermediate housing 500.

At this time, the pressing protrusion 420 of the piston 400 is disposed in the punch hole 510 of the intermediate housing 500.

Next, the diaphragm 600 is placed on the intermediate housing 500.

At this time, in the diaphragm 600, the interlocking member 610 is disposed at a position corresponding to the pressing protrusion 420, and the interlocking member 610 is fixed to the pressing protrusion 420 using bolts.

Accordingly, the diaphragm 600 is naturally fixed on the intermediate housing 500.

Next, the absorption valve 810 is joined to the partition groove 710 of the entrance plate 700 to shield the absorption hole 711.

At this time, the buffering protrusion 811 formed on the absorption valve 810 protrudes to the outside of the access plate 700.

Next, the drain valve 820 is coupled to the center groove 720 formed at the front center of the access plate 700.

Then, the inlet plate 700 to which the absorption valve 810 and the drain valve 820 are coupled is coupled onto the diaphragm 600.

At this time, the interlocking member 610 on the diaphragm 600 corresponds to each absorption hole 711 of the access plate 700, and between the access plate 700 and the diaphragm 600, (Pressurization) is generated.

At this time, it is natural that airtightness should be maintained between the access plate 700 and the diaphragm 600.

Next, the access plate 700 is covered with the head cover 900.

At this time, the head cover 900 is seated at the edge of the intermediate housing 500, and the buffer protrusion 811 projected through the access plate 700 is inserted into the insertion boss (not shown) formed in the inflow space 911 in the head cover 900 911a.

The drain valve 820 coupled to the center groove 720 of the access plate 700 is disposed in the drainage space 921 of the head cover 900 and the drainage valve 820 is disposed between the drainage space 921 and the inlet space 911 Confidentiality is maintained.

Next, the coupling to the suction pump P is completed by fastening the edge of the head cover 900, the edge of the intermediate housing 500, and the edge of the side housing 300 using bolts.

Then, the suction pump P coupled as described above is fixed to the other surface of the installation 120.

At this time, it is preferable that a guide member 130 is interposed between the other surface of the installation box 120 and the suction pump P.

This is for further strengthening the fixing force of the suction pump P to the other surface of the installation box 120 and guiding the coupling position.

That is, since the fixing surface of the side housing 300 opposed to the other surface of the installation box 120 is not formed flat, the fixing force of the suction pump P to the other surface of the installation box 120 may be reduced. And the fixing part of the suction pump P is made flat by using the guide member 130 so that the fixing force of the suction pump P can be increased to the mounting case 120. [

 Hereinafter, the pumping action of the suction pump fixed inside the hard case will be described with reference to FIGS. 4A and 4B.

The handle H is axially coupled to the shaft hole 110 exposed through the case hole 5a of the hard case 5 to rotate the main gear 100. [

At this time, the user rotates the handle H at a speed of 60 to 70 rpm by hand, and the rotational speed of the driven shaft 210 is about 700 rpm due to the gear ratio between the main gear 100 and the driven gear 210.

The cam shaft 410 of the piston 400 eccentrically rotates and the cam portion 410 having an inclined surface with respect to the inner side surface of the side housing 300 is rotated along with the eccentric rotation of the side housing 300, As shown in FIG.

That is, the cam portion 410 rocks with reference to the inner surface of the side housing 300, thereby causing the pressing projection 420 of the piston 400 to linearly move.

Thereafter, the three pressing protrusions 420 repeatedly pressurize / release the three points of the diaphragm 600, and the pressure inside the diaphragm 600 is generated due to the pressing / releasing action of the pressing protrusions 420 do.

That is, three points of the diaphragm 600 corresponding to the three pressing protrusions 420 are also absorbed into the diaphragm 600 while swinging, that is, in a rectilinear motion (upward and downward motion in the drawing) The position of the pressing protrusion 420 corresponding to one side of the cam portion 410 at a lower position is also lowered as shown in FIG. 4A, so that one side of the diaphragm 600 Absorbing pressure (self-absorption) is generated in one side of the diaphragm 600 because the diaphragm 600 is pulled downward.

As a result, the absorption valve 810 is opened and the absorption hole 711 of the access plate 700 is opened. The purified water flows into the diaphragm 600 through the inlet 910 and the inlet 911, do.

Then, as the cam portion 410 is rotated, one side of the diaphragm 600 is lifted as shown in FIG. 5B as the one side of the cam portion 410 at the lower position is raised while pushing up the pressure projection 420.

At this time, a drainage pressure is generated in one side of the diaphragm 600 to open the drainage valve 820, and the purified water introduced into the diaphragm 600 flows through the drainage hole 712, And is discharged outside.

At this time, the absorption valve 810 closes the absorption hole 711 by the drain pressure generated when the pressing projection 420 is raised.

At this time, the absorption valve 810 is raised by the drain pressure and brought into close contact with the partition groove 710. In this process, the buffer projection 811 of the absorption valve 810 is contracted in the insertion boss 911aa, Thereby buffering the valve 810.

On the other hand, the purified water discharged out of the access plate 700 through the drain hole 712 is discharged through the drainage space 921 of the head cover 900 and discharged through the discharge portion 920, thereby being supplied with drinking water.

Although a series of operations have been described step by step to facilitate understanding of the explanation, such a series of operations is performed as fast as the rotation speed of the cam portion 410, and is performed at three points of the diaphragm 600 by the eccentric rotation and rocking action of the cam portion 410 .

As described above, the suction pump assembly according to the present invention has a technical feature that the absorption pressure (self-excitation) and the drain pressure (pressurization) are sequentially generated in the diaphragm through the swinging action of the cam portion.

That is, since the self-exhalation and the pressurizing action are excellently performed in the diaphragm, it is possible to maximize the power output to the purified water of the portable water purifier using the RO filter.

Therefore, the purified water amount of the portable water purifier can be increased.

In addition, since the main gear and the driven shaft are constructed so that a self-restraining action and a pressing action can be generated manually by using the handle, there is a technical feature that there is no restriction on the installation place of the portable water purifier.

Furthermore, since there is no need for a power source, there is a feature that the economy can be improved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
