Description

FIELD OF THE INVENTION The present invention relates generally to electric toothpaste extractors,
More particularly, it relates to a toothpaste removal device which is activated by pressing a push button with a toothbrush. When the toothpaste container is empty, the user need only replace the toothpaste container.

Description of the Prior Art The typical toothpaste tubes currently in use are:
It has been used for many years now since it became generally accepted. This representative toothpaste tube is relatively easy to use, albeit with some drawbacks. Among its drawbacks are cracks and tears on the sides of the tube, and excessive pressure applied to the tube when the cap is improperly tightened on the tube, resulting in leakage between the tube extrusion and the cap. If the method of squeezing and rounding the tube is not uniform, toothpaste will remain in the tube without being used, or the cap will be removed or covered every time toothpaste is used, and the tube will be pressed too much. There is a problem in use such as pushing out an excessive amount of toothpaste or spilling the toothpaste on the washbasin or sink. All of these problems occur when children use toothpaste tubes.

So far, several types of toothpaste extractors have been announced. Dunning U.S. Pat. No. 3,198,389 discloses a toothpaste removal cabinet that uses two rolls to squeeze a toothpaste tube. Apuzzo
U.S. Pat. No. 4,234,104 describes a toothpaste extractor having a motor for driving two rollers which press the toothpaste tube. A closing mechanism is provided at the outlet from this toothpaste extractor,
Also, a manual switch for reversing the motor is provided. U.S. Pat. No. 4,258,864 to Karam-anolis et al. Describes a toothpaste dispenser with a motor that drives a roller that presses a tube of toothpaste. A manually operated switch is used to return the rollers, and a gate is used to close the outlet. Kane U.S. Pat. No. 4,403,714 describes a toothpaste extractor having a motorized roller for squeezing the toothpaste from a horizontally mounted toothpaste tube. The tube is inserted into the adapter and the outlet is blocked by lever 21. The motor is reversed with a manual switch. U.S. Pat. No. 4,629,095 to Smith describes a toothpaste removal device guided by a wheel-like wheel for passing a tube through a pair of pinch rollers. The toothpaste tube is reversed and passed through a hole that is closed by a swing stop closure.

The above-mentioned patent has several disadvantages. In these patents, the importance of having a flexible roller to evenly squeeze the tube cannot be recognized. The elasticity of the rollers is desired to accommodate tubes of different sizes and to accept obstructions within the tubes. Some of these patents mention that a spring can be attached to the roller, but the resilience provided by the spring is not recognized as causing imbalance or uneven squeezing of the tube.
Another problem is that these patents cannot provide a roller driving device. Only Dunning U.S. Pat. No. 3,198,389 defines a rotary drive for a roller. However, the driving device is based on a pulley system and is structurally expensive.
Also, various problems occur due to slippage of the pulley.

These patents also disclose the respective drawbacks of guiding the toothpaste tube between the rollers when the rollers begin to be used from the bottom of the toothpaste tube and when the tube is improperly placed or positioned relative to the roller. have. These drawbacks are significant because the toothpaste extractor must be suitable for various sizes of toothpaste tubes and curved tubes, and must be adjusted for incorrectly placed toothpaste tubes. is there. Further, the above-mentioned patents describe a roller in which the tube collides with the housing or the outlet of the toothpaste extractor by the roller, the tube is pulled from the outlet by the reverse rotation of the roller, or by the frictional force from the roller. Inability to address related issues. In these patents, the switch also has to be manually actuated to reverse the roller mechanism which has completed the pressing movement against the toothpaste tube, which has been completely automatic until then.

In addition, there is no description of a device for adapting, connecting and holding the tube in the device. Because toothpaste tubes vary in size and design, it is important to have adjustable or adaptable mechanisms to hold the tube and connect it to the mouth of the tube. Further, the aforementioned patent does not recognize the importance of making the outlet nozzle removable so that more clogged toothpaste can be removed.

Among other drawbacks are the easy-to-touch push buttons for activating the toothpaste removal device to clean and wipe the nozzles of the toothpaste removal device,
Other features that may be added to facilitate operation of the toothpaste removal device may not be recognized. The toothpaste extractor is also mounted on the outside for ease of use, but can be made more convenient by providing a removable wall mount or toothpaste holder to facilitate cleaning. Further, these patents increase the risk of electric shock due to the use of alternating current to drive the motor.

Therefore, the electric toothpaste removal device is easy to install and use, can hold the toothbrush and can be washed at the same time, prevents the occurrence of electric shock by using a DC converter, and properly and effectively applies the rollers. The toothpaste tube can be squeezed flatly and flexibly, and can be adapted to accommodate toothpaste tubes of various shapes and designs to hold the toothpaste tube in place and to prevent leakage. It is necessary to facilitate control of the toothpaste extractor without drying the toothpaste.

The roller gear box 69 has two holes for supporting the first and second rollers 70 and 74, and holes for supporting the first and second guide plates 78a and 78b. There are two upper bearing walls 69a, 69b having As the long screw 58 is turned, the upper and lower brackets 61 and 65 move together in either an upward or downward direction due to a forward or reverse driving force provided by the motor 32. During this upward or downward movement of the brackets 61 and 65, the contact between the rack 57 and the pinion 59 drives the first roller. The first roller 70 drives the second roller 74.

Both rollers 70 and 74 and both rollers are covered with roller cushion materials 70a and 74a made of a flexible material such as rubber, foam material or foam rubber. The pliable material allows the feed mechanism 60 to be used to allow the toothpaste container 20 to be more fully squeezed and to roll out wrinkles and other obstacles in the toothpaste container 20 of various sizes.
It is useful to guide the toothpaste container 20 between the rollers 70 and 74 when starting from the bottom of the toothpaste.

The distance between the rollers 70 and 74 and the thickness of the cushioning materials 70a and 74a allow the toothpaste container 20 to be squeezed sufficiently to remove the toothpaste without interfering with the movement of the rollers 70,74 and the feed mechanism 60. . The spacing between rollers 70a and 74a when covered with cushioning material is preferably 0.5 mm, and the thickness of the cushioning material is preferably 2.5 mm.

79e and 79f are fixed to both ends of the guide plates 78a and 78b, and
And 78b are kept at about 45 ° from horizontal. Washers 79g, 7
9h, 79i, 79j are supported by 79k, 79l, 79m, 79n with support shafts 79a and 79
b is held. However, the guide plates 78a and 78b are
It is possible to rotate to the horizontal position against the force of 9c, 79d, 79e, 79f. The guide plates 78a, 78b serve to guide the lower end 21 of the toothpaste container into the gap between the first and second rolls 70, 74 when the feed mechanism 60 starts at the bottom 21 of the toothpaste container 20. .

Guide plates 78a and 78b are provided between the rollers when starting a toothpaste container not placed parallel to the axial direction of the first and second rolls 70,74 at the bottom 21 of the new toothpaste container 20. It acts to direct the gap. Toothpaste container 20
Can be placed at any location where the main cross sectional axis of the container is within the axial 360 ° range of the first and second rollers 70 and 74. The guide plate causes the toothpaste container to be rotated such that the major cross-sectional axis is parallel to the axial direction of the rollers 70 and 71, except in certain situations. This exceptional state
It occurs when the bottom 21 of the toothpaste container 21 is wider than the tops of the guide plates 78a, 78b when 78a and 78b are pushed to the horizontal position. In this state, the toothpaste container 20 is the first
And the second rollers 70 and 74 can be rotated away from the axial direction, and furthermore, the angular range rotated or guided between the rollers is determined when the guide plates 78a and 78b are in the horizontal position. The bottom 21 of the toothpaste container is the upper end 78 of the guide plates 78a and 78b.

The guide plates 78a and 78b also include rollers 70 with cushioning material.
It is also useful for guiding a slightly bent toothpaste container into the gap between 74 and for guiding a partially empty toothpaste container before it is inserted into the toothpaste dispenser 10. is there. Guide plates 78a and 78b are leaf springs 79c, 79d, 79
The guide plates 78a and 78b do not prevent the feed mechanism 60 from reaching the upper part of the housing 12 because the guide plates 78a and 78b can rotate in the horizontal position against the force of the e and 79f. As a result, rollers 70 and 74 press to the tip of toothpaste container 20 before second switch 112 closes, and thus the toothpaste remaining in toothpaste container 20 before drive mechanism 30 reverses direction. The amount can be minimized.

A toggle bar 110 is mounted in a toggle bar holder 111 which is mounted to the housing by screws or other suitable fastening means. Feed mechanism 60 is the tip 23 of the toothpaste container 20
, The upper bracket 60 moves the toggle bar 110 to the second
Until the switch S2 is closed. Second switch S2
Automatically reverses the drive mechanism 30 that raises the feed mechanism 60, or lowers the toothpaste container 20 in the vertical direction, so that the protrusion 68 of the lower bracket 65 is the third switch.
In S3, the power supply of the motor 30 is cut off. At this time, the indicator light 15b is turned on to notify the user that a new toothpaste container needs to be installed.

FIG. 9 shows details of the gripping mechanisms 90a and 90b. Grasping mechanism 90
Both a and 90b are housing by screws or other suitable fixing means.

a and 92b and 94a and 94b respectively. Upper clamp
Both 92a and 92b and the lower clamps 94a and 94b are held in mechanical housings 96a and 96b that suppress vertical movement and movement in a direction perpendicular to the plane of FIG. However, fasteners 92a and 92b and 94a and 94b are
It can be moved horizontally by compression springs 98a and 98b and 99a and 99b which press 2b and 94a and 94b in opposite directions. The tips 92c and 92d of the upper fasteners 92a and 92b are concave so as to engage with the threaded neck of the toothpaste container 20. The lower fastener tips 94c and 94d are each concave so as to grip the neck under the screw of a typical U.S. toothpaste container. Depending on the design shape of the toothpaste container 20, the upper or lower fasteners 92a and 92b or 94a and 94b.
Need one of:

The user of the toothpaste extractor 10 simply puts his hand inside the housing and uses the upper and lower fasteners 92a and 92b and 94a and 9a.
The gripping mechanism can be operated by pulling apart 4b and removing or inserting the toothpaste container. The gripping mechanisms 90a and 90b are spring-pressed, so that they can adapt to the dimensions of the neck of the attached toothpaste container 20.

9 and 10 show details of the nozzle mechanism 80 and the push button 100. The push button 100 has a cap 102 and a downwardly facing protrusion 104. A compression spring 106 fits into the protrusion 104 and is compressed between the cap 102 and the housing 12 to push the push button 100 against the retaining portion 108 and hold it in a vertical position. In this state, the first switch S1 is open. When the push button 100 is pressed, the protrusion 104 closes the first switch S1. As a result, the motor 32 is driven in the forward direction, driving the feed mechanism 60 upward with respect to the toothpaste container.

The nozzle mechanism 80 includes a cylindrical portion cover 84, a nozzle adjustment lever 8
8. It has an outlet 82, a tubular fitting 86 and a spring 85. The cylindrical portion 81 has a thread at the upper end for mounting the cylindrical cover 84 and an opening at the lower end through which the tubular fitting 86 is passed. The cylindrical portion 81 is attached to a tip of the housing 12. The extrusion port 82 has an L-shaped curved portion 82 for supplying the toothpaste 24 to the portion overlying the push button. The shoulder portion 83 of the nozzle mechanism is directly below the curved portion 82a. Nozzle adjustment lever 88, cap cover 84 and spring 85
Covers the lower end of the extrusion port 82 and is retained between a shoulder portion 83 and a tubular fitting 86 that is screwed to the lower end of the extrusion port 82. The tubular fitting 86 has a conical neck 87 for fitting or connecting to and pushing down the mouth 28 of the toothpaste container 20 mounted within the housing 12.
This allows it to fit the mouth of toothpaste containers of various sizes. At the upper end of the tubular fitting 86 is a ridge 93
Is provided. The protruding edge 93 contacts the bottom of the cylindrical portion 81 to restrict the downward movement of the tubular fitting 86. The spring 85 pushes the tubular fitting 86 downwards while the toothpaste is being extracted from the toothpaste container 20 and remains in contact with the mouth of the toothpaste container 20.

As shown in FIG. 9, the nozzle adjustment lever 88 is
Has an annular portion 88a mounted around it. A part of the annular portion 88a has an inclined surface 82 and is pushed into the inclined surface 82b of the extrusion port 82. Therefore, by moving the lever 88,
The extrusion port 82 moves accordingly or axially to move the tubular fitting 86 up and down the mouth of the toothpaste container 20.

Occasionally, the toothpaste dries in the outlet 82 and clogs the outlet 82. In such a case, the nozzle mechanism 80 can be removed and immersed in warm water or removed by other methods. The nozzle mechanism 80 is removed by rotating and removing the screwing of the cylindrical portion cover 84 from the cylindrical portion 81.

There are two problems that the present invention solves with respect to moving the feed mechanism 60 up or down along the toothpaste container 20. The first problem is that the toothpaste container 20 is diagonal,
Or, it occurs when the nozzle mechanism 80 collapses. The second problem is that the neck 26 of the toothpaste container 20 is
Occurs when pulling out from the gripping mechanisms 90a and 90b. Both problems are affected by the vibrations and non-vertical forces exerted by rollers 70 and 74. However, the first problem is mainly caused by the excessive vertical force applied in the upward direction, and the second problem is caused by the excessive vertical force applied in the downward direction.

The interaction between the long screw 58, the brackets 61 and 65, the rack 57, the pinion 59, and the cushioned rollers 70 and 74 provides a smooth rotational movement along the toothpaste container 20, providing vibration and non-vertical The force in the direction is negligible compared with the hardness of the toothpaste container 20 and the holding ability and stabilizing ability of the gripping mechanisms 90a and 90b.

The upward and downward forces on the toothpaste container 20 are generated by the rollers 70, 74 when the feed mechanism 60 is raised or lowered along the toothpaste container 20, and is also mixed with the cushioned rollers 70, 74. It is generated by frictional contact with the toothpaste container 20. In the present invention, these forces tend to balance each other. However, cylindrical mounting parts
86 is elastically mounted in the nozzle mechanism 80,
Contact with the mouth of the toothpaste container 20 is maintained, and the holding and stabilizing forces of the gripping mechanisms 90a and 90b are independent of the force exerted by the rollers 70,74 by the up and down movement and friction of the feed mechanism 60. The neck 26 is held.

The present invention also contemplates that the toothpaste container 20 is squeezed or compressed by the ascending or descending speed of the feed mechanism 60 and the rotational speed of the rollers 70, 74 to obtain the toothpaste 24 at the desired speed from the nozzle mechanism. Designed.

The drive mechanism or motor 30 operates at a speed of 5000 revolutions per minute. With the motor 32 and gear 40, the long screw 58
Driven by 34.5 revolutions. The feed mechanism 60 moves up or down by 1 millimeter per revolution of the long screw 58 depending on the direction in which the motor is driven. As a result, the feed mechanism moves at a speed of 34.5 mm per minute, or 0.575 mm / s. Other drive mechanisms 30 can be devised and used, but here
A preferred drive speed of the feed mechanism 60 for obtaining the toothpaste 24 from 82 at a desired flow rate and for holding the toothpaste container 20 in the normal position without being crushed by the gripping mechanisms 90a, 90b will be described.

FIG. 11 shows a control system circuit of the present invention. When the first switch S1 is closed, the circuit is complete and the motor begins to rotate in the forward direction to squeeze the toothpaste out of the toothpaste container 20. When the push button 100 is released and the first switch S1 is opened, the start pulse signal generator Q sends out a signal to start the third transistor TR3, which in turn activates the relay RL. . As a result, the direction of the motor 32 is reversed and the feed mechanism 60 is lowered. The amount of time that the third transistor TR3 sends a signal to the relay RL to reverse the motor is preset and adjustable. Preferably, this amount of time is set to 0.5 seconds or nearly that value. push button
When 100 is released, the automatic reversing characteristic operates for a predetermined set time, releasing the pressure on the toothpaste container 20 and when the push button 100 is released, the toothpaste 24 excessively leaks from the nozzle mechanism 80. It is designed to prevent you from doing so.

When the second switch S2 is closed by the toggle bar 110, the relay RL is set to the active state via the contact point of the transistor TR1 and the third switch S3. In this state, the motor 32 moves in the reverse direction. Transistor TR2 remains "on" until it returns to its original position due to its self-holding circuit. When the feed mechanism 60 reaches the "lowest position", the third switch S3 is opened. As a result, the second transistor TR2 is turned off and RL returns to the normal state. Therefore, the initial state of the circuit system is restored.

In some cases, it may be preferable to reverse the direction of the motor 32 before the second switch S2 closes. Such a case occurs when the user wants to replace the toothpaste container 20 or fix the position of the toothpaste container 20. This manual reverse rotation of the motor 32 can be performed by putting a hand in the housing and lifting the toggle bar 110 to close the second switch S2. If desired, a fourth switch S4 (only shown in FIG. 11) can be added outside the housing 12 to manually reverse the motor. FIG. 12 shows a preferred circuit of the DC converter.

FIG. 20 shows an electric circuit system of the embodiment of the present invention shown in FIGS. When the automatic switch S1 is activated by the toothbrush and turns on, the motor is turned on and the toothpaste is squeezed out. When switch 1 is turned off by removing the toothbrush, the motor power is turned off and at that moment (approx.
A blocking pulse is generated in the blocking circuit Q (counterclockwise rotation blocking pulse circuit) for 0.5 seconds, the transistor (TR3) is turned on momentarily (about 0.5 seconds), and the on / off relay RL is simultaneously excited. Then, the contact is changed from the contact (a) to the contact (b), the motor is rotated at the moment of the closing pulse, and the natural flow of the toothpaste is stopped.

When the toothpaste tube is almost empty, switch S2 is turned on, TR1 is turned on, RL is simultaneously energized, and the motor rotates counterclockwise. Switch S2
Transistor TR2 is already on,
Since the off relay RL is maintained in the excited state, the lowering of the feed mechanism 260 automatically causes the cutoff state. The motor rotates counterclockwise until the feed mechanism 260 contacts the switch S3, breaking the circuit, turning TR2 off, and deenergizing RL to stop the roller in its initial position. . After the toothpaste tube is installed,
When the user touches switch S1 to insert the end of toothpaste container 220 between rollers 263 and 264, the feed mechanism is lowered (this action can be accelerated by pressing push button SF). . When it is necessary to replace the tube in use, the user presses the switch S2 to lower the feed mechanism.

Between the point (a) and the motor, the limiting current-like resistance R reduces the clockwise rotation speed of the motor while the roller is squeezing the toothpaste tube and accelerates the counterclockwise speed. Directly connected. The manual switch SF is in parallel with the resistor R and the switch S1. The speed of the motor due to the manual switch SF is accelerated and the feed mechanism descends rapidly until the roller hits the bottom or end of the toothpaste tube. The feed mechanism 260 gradually descends when the switch S1 is touched with a toothbrush.
