Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a cleaning water supply device that is capable of being generating a vacuum attraction to draw a cleaning fluid into a water flow so that the cleaning fluid and the water flow mix together quickly and evenly, this obtaining cleaning water.

2. Description of the Prior Art

A conventional cleaning water supply device is used on installed on the showering equipment and comprises a channel with a decreased and then increased diameter disposed adjacent to an outlet and an intake in the channel to flow water, wherein a vacuum attraction generates in the intake so that the cleaning fluid in the store box is drawn into the channel via the intake so as to mix with the water, thereby spraying cleaning water out of the outlet.

However, such a conventional cleaning water supply device still has the following defects:

1. When the showering equipment is adjusted in a water splash mode, the pressure changes easily, so that the water or the cleaning water will flow back to the store box from the intake, polluting the cleaning fluid and jamming the intake by impurities in the water.

2. If water becomes lower, the cleaning fluid can not be drawn, hence the cleaning fluid can not be mixed.

3. A size of the intake is fixed, therefore an output quantity of the cleaning fluid will not increase with the water pressure, such a cleaning fluid with a low mixing ratio will influence the quantity of the cleaning water.

4. The intake only has a single opening, so the cleaning fluid can only flow into the channel from the single opening without mixing with the water quickly and evenly.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a cleaning water supply device that is capable of overcoming above-mentioned shortcoming.

The secondary objective of the present invention is to provide a cleaning water supply device that a vacuum attraction generates on the connection of the inlet and the outlet channels, hence the wing of the valve member is retracted inward flexibly by the vacuum attraction to open and guide the through channel, such that the output tunnel of the storing unit is turned on by using the control unit to draw the cleaning fluid a of the chamber into the connection of the inlet and the outlet channels via the output tunnel, the intake, and the through channel so that the cleaning fluid mixes with the water flow automatically, thereby obtaining the cleaning water.

A further objective of the present invention is to provide a cleaning water supply device that due to the open cross-section area of the through channel is adjusted with a change of the water pressure, when the water pressure decreases to lower the open cross-section area, the cleaning fluid is outputted decreasingly, while the water pressure increases to enhance the open cross-section area, the cleaning fluid is outputted increasingly so that the cleaning fluid and the water flow are mixed together within a certain range, thus achieving a suitable concentration of the cleaning water.

Another further objective of the present invention is to provide a cleaning water supply device that partial cleaning fluid flows into the annular space of the through channel from one of the second holes, and another partial cleaning fluid flows into the annular space of the through channel from the other three second holes along the path in turn so that the cleaning fluid is capable of flowing into the annular space completely to mix with the water flow quickly and evenly.

Also another further objective of the present invention is to provide a cleaning water supply device of which the mixing unit is capable of being installed on the showering equipment which is adjusted in a water splash mode, wherein the water pressure is changed to generate a back pressure in internal pipes of the showering equipment, and then a circular wing of a circular valve member senses the back pressure to further close a through channel automatically so that a water flow or the cleaning fluid is stopped to flow back to the output tunnel and a chamber, thus preventing the cleaning fluid from being contaminated. Likewise, impurities in the water are stopped to flow into the through channel or an intake, preventing the through channel or the intake from being jammed by the impurities.

Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

The valve member 10b includes a fitting portion 182 retained in the second groove 133 of the first plug 103 and the wing 181 extending from the fitting portion 182; a cross section of the valve member 10b is formed in a V shape, and the valve member 10b is made of a rubber or a silica gel material to obtain an inward retracting deformation and outward expending force.

The storing unit 20 as illustrated in FIG. 7, is connected with the channel assembly 10a of the mixing unit 10 and includes a chamber 21 to receive a cleaning fluid and an output tunnel 22 communicating with the chamber 21 and the intake 14, thus flowing the cleaning fluid outward; the cleaning fluid a in the chamber 21 is drawn into the connection of the inlet channel 11 and the outlet channel 12 along the output tunnel 22, the intake 14, and the through channel 13 after the through channel 13 are turned on as shown in FIGS. 10-12, thereafter the cleaning fluid mixes with a water flow b to form a cleaning water c.

The cleaning fluid a is selected from soap fluid, shower gel, and shampoo.

The storing unit 20 includes a store box 20a, an engaging member 20b, and two locking components 20c, wherein

the store box 20a includes the chamber 21, the output tunnel 22, and two opposite first tabs 23 between which is defined an installing room 231.

The store box 20a further includes a seat 201, a cover 202, a first convey tube 203, and a second convey tube 204.

The seat 201 is provided to be the first tabs 23 and includes a first slot 232 and a passage 233 communicating with the first slot 232 and the installing room 231, the passage 233 of the seat 201 includes a third bore 234 secured on a middle section thereof. It is preferably that a diameter of the third bore 234 is more than that of the passage 233, but the diameter of the third bore 234 is capable of being equal to that of the passage 233. The seat 201 also includes a second slot 235 formed on an outer surface thereof.

The cover 202 is removably fixed in the first slot 232 of the seat 201 and is applied to define the chamber 21, wherein an opening of the chamber 21 corresponds to one end of the passage 233 of the seat 201.

The seat 201 includes an air inlet (not shown) arranged thereon in response to the opening of the chamber 21 to flow air, such that the cleaning fluid in the chamber 21 is drawn into the output tunnel 22.

The engaging member 20b is retained with an outer surface of the channel assembly 10a and includes two opposite second tabs 24 inserted in the installing room 231 of the store box 20a.

In this embodiment, the locking component 20c is a first bolt to be inserted through the first and the second tabs 23, 24 and is screwed with one of the first tabs 23 so as to be moved to contact with another first tab 23, hence the engaging member 20b is fixed on the channel assembly 10a.

The control unit 30, as illustrated in FIGS. 8 and 9, is installed on the storing unit 20 to be shifted to control the output tunnel 22 of the storing unit 20 to output the cleaning fluid.

The control unit 30 further includes a valve core 31 passing through the third bore 234 of the seat 201, an operating bar 32 disposed on one end of the valve core 31 to drive the valve core 31, a limit block 33 secured on another end of the valve core 31; wherein the valve core 31 includes a small-diameter stem segment 311 formed thereon in response to the passage 233 of the seat 201, and the stem segment 311 includes two spaced close portion 312 extending from an outer surface of the stem segment 311 to rotate with the valve core 31 so as to close the third bore 234; the limit block 33 is inserted by a second bolt 34 to screw with the valve core 31 so as to be further fixed on the seat 201 with the valve core 31, and the limit block 33 also includes a positioning peg 331 disposed on an inner surface thereof to be received in the second slot 235 of the seat 201 and to rotate between a first position P1 and a second position P2 of the second slot 235 as illustrated in FIG. 13; when the positioning peg 331 is located at the first position P1, the output tunnel 22 is closed by the close portion 312 of the valve core 31 as shown in FIG. 14; and when the positioning peg 331 is located at the second position P2, the close portion 312 of the valve core 31 is rotated to turn on the output tunnel 22 as illustrated in FIG. 10.

The cleaning water supply device 1 is fixed onto a water supply pipe, wherein when the water supply pipe is not tuned on, the wing 181 of the valve member 10b of the mixing unit 10 abuts against the through channel 13 as shown in FIG. 4 to close the through channel 13.

While the water supply pipe is tuned on, the water flow b flows outward from the inlet channel 11 of the mixing unit 10 via the through channel 13 and the outlet channel 12 as shown in FIGS. 10 and 11. It is to be noted that because a diameter of the first bore 16 of the inlet channel 11 becomes decreased along a water flowing direction, and the diameter of the second bore 17 is more than that of the outlet end of the first bore 16 so that a connection of the first and the second bores 16, 17 forms a smallest flowing cross section, when water flows through the smallest cross section, a low pressure and a high flowing speed generate to obtain a largest vacuum according to the venturi principle so that the vacuum attraction generates on the connection of the inlet and the outlet channels 11, 12, hence the wing 181 of the valve member 10b is retracted inward flexibly by the vacuum attraction to open and guide the through channel 13. In the meantime, the output tunnel 22 of the storing unit 20 is turned on by using the control unit 30 to draw the cleaning fluid a of the chamber 21 into the connection of the inlet and the outlet channels 11, 12 via the output tunnel 22, the intake 14, and the through channel 13 so that the cleaning fluid a mixes with the water flow b, thereby obtaining the cleaning water c.

As the output tunnel 22 of the storing unit 20 is turned off by ways of the control unit 30 as illustrated in FIGS. 13 and 14 to stop supplying the cleaning fluid a, the mixing unit 10 supplies the water flow b once more.

The output tunnel 22 is controlled by manually operating the operating bar 32 of the control unit 30, and due to the positioning peg 331 of the limit block 33 only rotates between the first and the second positions P1, P2 of the second slot 235 as shown in FIG. 13, the operating bar 32 is merely shifted between an turning-on and an turning-off positions as illustrated in FIG. 14. When the operating bar 32 is rotated toward the turn-on position, the positioning peg 331 is limited at the second position P1, and the close portion 312 of the valve core 31 is rotated to turn on the output tunnel 22 so that the cleaning fluid flows outward. While the operating bar 32 is rotated toward the turn-off position, the positioning peg 331 is limited at the first position P1, and the close portion 312 of the valve core 31 stops the output tunnel 22 so that the cleaning fluid can not flow outward, thereby starting and stopping a supply of the cleaning fluid easily and quickly.

It is to be noted that the intake 14 is comprised of one of the first holes 141 of the body 101 and the four second holes 142, and the second holes 142 are in communication with the path 145 as illustrated in FIG. 12; thereby partial cleaning fluid flows into the annular space 131 of the through channel 13 from one of the second holes 142, and another partial cleaning fluid flows into the annular space 131 of the through channel 13 from the other three second holes 142 along the path 145 in turn so that the cleaning fluid is capable of flowing into the annular space 131 completely to mix with the water flow quickly and evenly.

Because each second hole 142 communicates with the first hole 141 through the path 145, if anyone second hole 142 does not correspond to the first hole 141, the cleaning fluid still can flow into the through channel 13 equally and efficiently. In addition, the plug member 102 is fixed in the first groove 15 of the body 101 easily and quickly.

The quantity of the first hole 141 and the second hole 142 is not be limited as described in this embodiment.

The cleaning water supply device 1 is capable of drawing the cleaning fluid automatically by using the vacuum attraction so that the cleaning fluid mixes with the water flow. Also, the wing 181 of the valve member 10b allows to deform to further control the through channel 13.

For example, when a water pressure of the mixing unit 10 becomes lower, the vacuum attraction in the through channel 13 will be lowered, accordingly an inward retracting deformation of the wing 181 becomes decreased to lower an open cross-section area of the through channel 13, such that the vacuum attraction generate a great influence so that the cleaning fluid is attracted into the water flow well at a lower water pressure.

Due to the open cross-section area of the through channel 13 is adjusted with a change of the water pressure, when the water pressure decreases to lower the open cross-section area, the cleaning fluid is outputted decreasingly, while the water pressure increases to enhance the open cross-section area, the cleaning fluid is outputted increasingly so that the cleaning fluid and the water flow are mixed together within a certain range, thus achieving a suitable concentration of the cleaning water.

A difference of a cleaning water supply device 1 of a second embodiment of the present invention from that of the first embodiment comprises:

a shower component 40 screwed on an outlet end of a body 101 of the channel assembly 10a and including a knob head 41 and a spraying set 42 fixed on the knob head 41 to adjust a showering angle so that the cleaning water supply device 1 is used in the showering equipment. When taking a shower, an output tunnel 22 is turned on to spray cleaning water, and then the output tunnel 22 is turned off to spray showering water.

Referring to FIG. 15, as the showering equipment is adjusted in a water splash mode, the water pressure is changed to generate a back pressure in internal pipes of the showering equipment, and then a circular wing 181 of a circular valve member 10 senses the back pressure to further close a through channel 13 automatically so that a water flow or the cleaning fluid is stopped to flow back to the output tunnel 22 and a chamber 21, thus preventing the cleaning fluid from being contaminated. Likewise, impurities in the water is stopped to flow into the through channel 13 or an intake 14, preventing the through channel 13 or the intake 14 from being jammed by the impurities.

With reference to FIG. 16, the channel assembly 10a of the first embodiment is comprised of the body 101, the first plug 103, and the second plug 104. But a first part member 105 and a second part member 106 are allowed to be screwed together to form the body 101, wherein the first part member 105 is integrally formed to generate a main structure of the first plug 103 which includes the first bore 16 and the second groove 133, and the second part member 16 is directly formed to generate a main structure of the second plug 104 which includes the second bore 17, the recess 143, and the projection 144. It is preferable that the second part member 106 is formed to obtain the first hole 141 of the body 101, thereby simplifying production process and lowering production cost.

A difference of a cleaning water supply device 1 of a third embodiment of the present invention from that of the first embodiment comprises:

a storing unit 30 only having the store box 20a without the engaging member 20b and the two locking components 20c of the first embodiment, and a seat 201 formed in a cylinder shape, a cover 202 retained with one end of the cover 201, and a cylindrical chamber 21 defined between the seat 201 and the cover 202.

The seat 201 includes an output tunnel 22 directly formed therein without having the first convey tube 203 and the second convey tube 204 of the first embodiment, a small-diameter tube segment formed on one end thereof in response to the cover 202, wherein the small-diameter tube segment includes the output tunnel 22 arranged therein, and a distal side of the tube segment is coupled with the first hole 141 of the mixing unit 10 in a quick removing or a screwing manner so that the storing unit 30 and the mixing unit 10 are connected together easily and quickly. In addition, a structure of the storing unit 30 is simplified to lower production cost.

The air inlet of the first embodiment to communicate with the chamber 21 is fixed on the seat 201, while an air inlet 25 of the third embodiment is secured on a suitable position of the cover 202 to feed air.

Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
