Description

  The present invention relates to a liquid take-out apparatus, and more particularly to an apparatus for taking out soap liquid and shampoo in a bathroom, a bathroom, a toilet, and the like.

2. Description of the Related Art Conventionally, a liquid take-out device has a container as shown in FIG. 8 or FIG. 7 (Japanese Utility Model Publication No. 42-136648) mounted upside down, and a pressing member attached to the lower end of the container, as is often seen in toilets. In some cases, the valve is opened by pushing it manually, and the liquid is taken out by dropping due to gravity.
Japanese Utility Model Publication No. 42-136648

In the conventional type of soap solution take-out device, the structure is complicated, and further, the packing for sealing the valve mechanism by reciprocation is ring-shaped, so that it becomes inoperable due to wear or material fatigue. There was.
Especially when silicone rubber is used for packing, animal oil may be used because it is easy to dry, but it is disliked that the product image is damaged by BSE.
In such a situation, cost is required due to breakdown and maintenance, which is a burden for large toilets such as hotels and dormitories. In the above-described conventional configuration, when taking out the soap solution, if the valve mechanism is sometimes pushed by hand, the soap solution may not come out. This is because the soap solution tends to harden when it comes into contact with air.

  The present invention improves the above-mentioned problems, extends the packing in the opposite direction as a flare with a cross-sectional plate shape, and repels it to provide a seal structure having the same resistance as the rubber packing, and the seal structure of the check valve mechanism It is an object of the present invention to provide a liquid take-out device that eliminates or eliminates trouble and maintenance.

  In addition, in this type of conventional liquid take-out device, the discharge of the liquid is stopped only by the check valve after the liquid is taken out, so that the valve breaks or the valve stops incompletely. However, in the present invention, it is an object to obtain a liquid take-out device that can use the check valve structure of the pump part both at rest and as a sealing structure.

  Further, in the conventional liquid take-out device, as shown in the conventional examples of FIGS. 8 and 7 (Japanese Utility Model Publication No. 42-136648), the user is located behind the pressing member 7 so that the user is behind the pressing member 7. The hand must reach out, and the position is difficult to see from above the user, so the liquid sometimes drops off the hand. SUMMARY OF THE INVENTION An object of the present invention is to allow easy cleaning by using a liquid flow path in a discharge member that performs a pumping action, and bringing a liquid discharge pipe close to a hand for washing.

  The pump mechanism includes a body part that communicates with the attachment / detachment part, a discharge member that reciprocates within the body part, and performs a pumping action, and a discharge member. The discharge passage is provided with a check valve slidably provided on the discharge pipe side, and a flow path is provided between the check valve and the discharge member. The check valve is a liquid take-out device that is provided with a pressing member that opens the flow path and closes the flow path when returning to open the opening to the discharge pipe and presses the discharge member. provide.

The check valve has a hole shape that fits with the abutting portion to form a flow path, and a seal piece portion that has a flare cross section in the radial direction extends in the opposite direction to seal with the main body portion. For this reason, the opening portion of the discharge pipe can be closed by the seal piece portion by the check valve while performing a sealing action with the main body portion.
Further, since the boss portion of the check valve is formed with a flow passage that is connected to and communicates with the groove of the contact portion of the discharge member, the axial length can be shortened.

  A detachable member for detachably attaching a liquid container, a main body part, a discharge member that performs a pumping action that slides in the main body part, and a discharge pipe, wherein the discharge pipe is inside the end of the stationary position of the discharge member. For the one that is provided in contact with the liquid and takes out the liquid, it is not far away, so the hand does not go wrong.

  As described above, according to the present invention, in such a conventional liquid take-out device, the discharge of the liquid is stopped only by the check valve after the liquid take-out is finished, so that the valve is broken or completely closed. In the present invention, there is a risk of leakage, but in the present invention, the discharge member also has resistance, and the check valve seal structure itself is also used to provide a valve function for preventing leakage to the outside when stationary. As a result, double sealing is sufficient, and the check valve is formed in a circumferential shape with respect to the main body in order to provide elasticity by extending the seal piece with a flare cross section in the radial direction in the opposite direction. Thus, a sealing member similar to rubber was obtained, and a packing configuration that could not be dried was obtained.

  Further, when performing the pumping action, as described above, the check valve structure of the present invention has a dual role of sealing the outside with the check valve itself, so the number of parts is reduced. It is.

  An embodiment of the present invention will be described based on an example with reference to the drawings. FIG. 1 shows one embodiment of the liquid take-out apparatus of the present invention.

  In the case shown in FIG. 8, the conventional method is attached, but an example in which the liquid take-out device 1 is attached into an instrument that accommodates the liquid container 8 (in FIG. 7, the instrument is attached to a wall surface). Show. In the example shown in FIG. 6, the liquid container 8 in which the soap solution is stored is fixed to the wall surface of the washroom or the like via an appropriate attachment. The liquid take-out device 1 is provided with a liquid container 8 containing a shampoo or the like so as to be detachable on the liquid take-out device 1 with the liquid take-out port facing downward. In any of the mounting examples, the liquid take-out device 1 of the present invention can be applied if the design is appropriately changed.

  The liquid container 4 is attached to the screw part 30 of the attaching / detaching part 3 of the take-out device 1 by being screwed with a screw outside the liquid container 8. Further, as described above, the container 8 may be directly assembled as shown in FIG.

  As shown in FIG. 1, a spherical check valve 300 is accommodated in the valve seat 301 in the detachable portion 3. The check valve 300 closes or opens the suction port 302. The detachable part 3 is attached to the main body part 2 of the liquid take-out device 1. The main body 2 has a cylindrical shape, and a discharge member 4 is provided inside the main body 2 and slides in the main body 2 to perform a pumping action.

The structure of the discharge member 4 includes a main body 40, and the main body 40 is constantly pressed rightward in FIG. 2 by a spring 201. In this example, since the spring 201 is stored in the internal space 401, the movement of the spring is stabilized. The discharge member 4 is automatically returned by the spring 201 in the reciprocation of the reciprocation.
Behind the main body portion 40 is an introduction portion 42 that is smaller than the cross-sectional area of the main body portion 40, and forms a passage for liquid to enter between the main body portion 2. In this example, the reason why the cross-sectional area is reduced is that the fluid resistance is reduced.
There is a gap 400 serving as a liquid passage between the outer side of the discharge member 4 and the main body portion 40 of the cylindrical body 2, and when the discharge member 4 moves to the left as shown in FIG. It flows to the right side of the figure through the gap 400 which is a liquid passage between them. As the liquid passage, the gap 400 can be narrowed and a thin tube can be formed in the blind portion of the outer discharge member 4 and used.

Further, at the front end portion of the discharge member 4, there is an abutting portion 41 that is smaller than the cross-sectional area of the discharge member 4 and extends in the axial direction, and the seal member 6 is fitted therein.
The situation shown in FIG. 2 is when stationary, but the seal member 6 is stationary in contact with the wall at the right end of the main body 2 in the figure, and the opening of the discharge tube 7 is at the lower end thereof. In the state, the seal member 6 which is a check valve closes the opening of the discharge pipe 7. It can be seen that the discharge tube 7 can then be placed in a position closest to the user for the liquid.

The check valve 6 may be loosely fitted to the contact portion 41 so as to be slidable. The check valve 6 is placed at a position as shown in FIG. As shown in FIG. 5, the check valve 6 is made of synthetic resin and has a hole 60 that fits into the abutting portion 41 and a seal piece portion that has a flared cross section in the radial direction from the boss portion 601 of the hole 60. 61, 61 extends in the opposite direction and is formed in a circumferential shape.
For this reason, it becomes possible to have elasticity similarly to the rubber packing, and the seal structure is obtained by repelling and repelling the main body 2. Unlike silicone rubber, it can be made of synthetic resin and is resistant to drying. Furthermore, since it does not move even if it is tilted sideways, the seal is sufficient.

  Further, since the seal piece portions 61 and 61 are provided on both sides, when the discharge member 6 moves backward and stops, the liquid passes through the opening of the discharge pipe 7 so that the seal piece portions 61 and 61 are circumferential from both sides. Since it is sandwiched with elasticity, it becomes a check valve that prevents outflow to the outside. That is, the seal piece 61 is closed over the opening of the discharge pipe. The seal member 6 is slid to the left in FIG. 3 as shown in FIG.

The check valve 6 is fitted in the abutting portion 41. As shown in FIG. 5, the abutting portion 41 is provided with grooves 410 at a rate of about 120 degrees. That is, a flow path is formed between the check valve 6 and the boss 601 of the check valve together with the groove 410. Since there is the groove 410 between the check valve 6 and the abutting portion 41, the liquid flows to the right through the groove 410. Further, the contact portion 41 is provided with a pressing member 5 which is moved by being pressed from the outside, and the discharge member 4 is reciprocated by pushing the discharge member 4 to move the discharge member 4 to perform a pumping action. The pressing member 5 may be provided with a lever member that moves the pressing member 5 by rotation as shown in FIG. In this example, the groove 410 is provided every 120 degrees, but the angle ratio can be appropriately selected.
It is also possible to provide a pore 602 in the boss portion 601 of the check valve 6 and use it for flow rate adjustment.

  However, if the pressing member 5 is pressed, it will collide with the abutting portion 41 and the flow from the groove 410 will be blocked in this state. Therefore, as shown in FIG. In order to form the gap 511, it is provided on the end plate 50. For example, even if the tip of the pressing member 5 hits the abutting portion 41 of the discharge member 4, it is more radial than the gap 511 inside the protrusion 510. A flow toward the outside is formed.

In this example, the protrusion 510 has a rod-like cross section, but it may be simply a cylinder or each column. Of course, the end plate 50 itself may have a groove instead of the protrusion 510. Further, a seal ring 501 is inserted into the end plate 50, and when the discharge part 4 and the pressing member 5 are stationary, the seal ring 501 prevents leakage to the outside. The pressing member 5 is stationary by moving the seal member 6 rightward in FIG.
As can be seen in this state, the stationary position of the seal member 6 stops in contact with the right end wall of the main body 2, and the opening of the discharge pipe 7 comes to the lower end for sealing. It is provided on the right side of the liquid take-out device, that is, the position closest to the user, and since the liquid does not leave far away, useless use of the liquid can be avoided.

The shape of the discharge tube 7 is a tapered portion 700 that gradually decreases as shown in FIG. 6, and an enlarged portion 701 that is enlarged at the lower end.
In this situation, when the liquid drips, the taper 700 is solidified at the lower end. On the other side, the enlarged portion 701 is in an enlarged shape, so it is difficult to solidify.
In a conventional tube having the same diameter, the portion of the tube where the liquid is accumulated is not constant. However, in the present invention, the place where the liquid is accumulated is specified.
The shape of the discharge tube 7 is a tapered portion 700 that gradually decreases, and the enlarged portion 701 that expands at the lower end portion, so that the liquid is accelerated as a fast flow downward. The accelerated liquid flows out because the enlarged portion 701 is enlarged, and does not stop and harden in the enlarged portion 701. With this configuration, it can be seen that the liquid hardly accumulates in the discharge pipe 7.

Next, the action state will be described. From the stationary state shown in FIG. 2, the pressing member 5 is moved forward and pushed to the left as shown in FIG. Then, the liquid closes the upper check valve 300 and flows into the lower main body 2, but the check valve 6 slides due to the force and inertia of the flow from the state shown in FIG. 2 to FIG. 3. To the right, the groove 410 below the check valve 6 is opened.
The flow from the container goes to the right through the gap 400 between the main body 2 and the main body 40. The flow toward the right flows further to the right through the opened groove 410 of the contact portion 41 below the check valve 6.

  Since the check valve 6 is in contact with the end plate 50 of the pressing member 5, the flow toward the right side of the check valve 6 is more radial than the gap 511 formed by the protrusion 510 of the end plate 50. Will fill the room to the right of the check valve 6.

Next, at this stage, when the pressing member 5 is released and brought into a stationary state, as shown in FIG. 4, it comes back and moves to the right side of FIG. 4 by the spring 201, but the check valve 6 is This time, it slides to the left as seen in FIG. 4 and blocks the flow path from the gap 440.
At this time, since the check valve 6 is moved to the left side, the opening of the discharge pipe 7 is opened and the liquid flows out to the outside.

  When the spring 201 pushes the discharge member 4 to the stationary position, the check valve 6 stops at the position shown in FIG. 2 and stops on the opening of the discharge pipe 7. Thus, since the seal piece 61 of the check valve 6 rests on the opening of the discharge pipe 7 so as to sandwich the opening, leakage of the liquid to the outside is prevented. In other words, it serves as both a sealing action in the pump action and a sealing action to the outside when the pump is stopped. Furthermore, since the valve has such a shape, the dimensions can be increased compared to a conventional ring-shaped valve, which is advantageous in terms of accuracy and strength, and material fatigue and the like are unlikely to occur.

  As described above, in the above embodiment, as shown in FIG. 2, the gap between the check valve 6 and the main portion 40 of the discharge member 4 is open because the liquid flows through the groove 410 of the contact portion 41. For this reason, in order to shorten the increase in the axial length, a radial hole 602 leading to the hole 60 of the check valve 6 is formed on the left side of the check valve in FIG. If the boss portion 601 is opened, the check valve 6 and the main body portion 40 of the discharge member 4 can be contracted to contact each other.

  As described above, the check valve applied to such a reciprocating pump is conventionally supported by a spring and causes a failure. However, in the present invention, the check valve is a free support, and the spring member is not supported by the valve. Not used at all. That is, a member such as a check valve for special closing is unnecessary. Moreover, since the inlet of the stationary discharge pipe 5 is closed by the check valve of the discharge member, the structure for enhancing the sealing effect is simple. Further, in the closed position, the inside does not come into contact with air, so that the soap liquid is not easily set.

  In the present embodiment, the liquid take-out device is installed in the horizontal direction, and the discharge pipe and the liquid container are installed in the vertical direction, but various other installation methods can be implemented by those skilled in the art.

  The liquid solidification automatic removal structure in the present invention has been described using soap liquid as an example, but other liquids may of course be used.
