Description

  The present invention relates to a liquid supply tank in a liquid consuming device such as a combustion heater or a humidifier.

  In general, liquid supply tanks used for liquid consumption devices such as combustion heaters and humidifiers are placed detachably upside down on the liquid receiving surface, for example, and the liquid receiving surface is lowered as the liquid is consumed such as combustion and vaporization. It is used as a cartridge-type liquid supply tank in which air bubbles are automatically introduced into the tank and the liquid in the tank is supplied through a discharge mechanism of a discharge cap provided at the discharge port.

  For example, a cartridge-type oil supply tank that supplies fuel oil such as kerosene has a metal outlet (tank base) protruding from the top of the metal tank body, and a dispensing mechanism equipped with a valve mechanism Place the pouring cap (oil filler cap) provided with an inversion state and place it on the oil pan (on the oil receiving surface) with the pouring mechanism opened by the pin-shaped part that is the valve opening action part. Then, when the fuel oil is consumed by combustion and the liquid level of the oil receiving tray is lowered, the fuel oil in the tank is poured out and supplied by the amount of bubbles while the bubbles are introduced into the tank through the pouring mechanism.

  When refilling the tank, take out the cartridge-type oil tank from the equipment, remove the spout cap from the spout, and fill the tank with fuel.

  The pouring cap attached to the pouring port of such a liquid supply tank has a structure in which the pouring cap is screwed onto a screw portion provided on the outer periphery of the pouring port. That is, the pour cap is removed by turning and attached by turning.

  In particular, in the case of such a configuration, as described above, since the liquid is placed on the liquid receiving surface in an inverted state via the pouring mechanism to supply the liquid, the pouring cap is easy to get dirty, and a hand is required when removing the pouring cap. I was worried about getting dirty.

  For this reason, various proposals have been made, for example, when the lever is pulled, the closing cap is released by spring bias, or a grip outer periphery is further added around the pouring cap.

  The applicant does not need to turn the handle and touch the extra part as much as possible. A non-threaded push button single-handed extraction cap has been developed that can be attached simply by pushing it over and can be easily removed by simply pushing the push operation part.

It concerns the liquid supply tank.

In addition, the present invention relates to a liquid consuming device such as a combustion heater, wherein the liquid supply tank according to any one of claims 1 to 10 is detachably provided.

  Since the present invention is configured as described above, the dispensing cap can be securely locked and unlocked with a single touch, and two or more push operation parts can be pushed together although they can be engaged and disengaged with a simple push operation. If it is not, the dispensing cap will not come off, and if you push it in reverse, the dispensing cap can be smoothly detached and detached, and only the one side that is pushed in will be detached and become unstable (half lock). Even if only one side is pressed due to impact or pressure difference, or if the other side is not fully pressed by mistake, an unstable state such as a half lock that is engaged / disengaged only on one side is unlikely to occur. It becomes an epoch-making liquid supply tank excellent in practicality, such as being able to be removed smoothly for the first time by pushing the push operation part.

In the second, third, and fourth aspects of the invention, the present invention can be easily realized with a simple configuration, and the pouring cap can be easily attached and detached with one hand. Even if only one side is pressed or only the other side is not fully pressed, only one side will not come off, and the locking part will be disengaged only when both pressing operation parts are fully pressed. This makes it possible to easily realize the present invention, which is less likely to cause half-locking and has excellent mounting performance, and is a very innovative liquid supply tank with excellent practicality.

According to the fifth aspect of the present invention, the movement of the cam pin with respect to the cam groove of the movement direction conversion coupling mechanism is smooth, and the locking portion is smoothly interlocked by the pushing operation portion via the movement direction conversion coupling mechanism. It moves in the direction of sinking, and it becomes an epoch-making liquid supply tank with excellent operability and durability.

Further, in the invention of claim 6 , a taper peripheral surface is provided below the straight hanging upper end peripheral surface for temporarily fitting and fixing the pouring cap at the spout, and this is formed so as to be gently long. The distance between the fitting position (temporary position) and the locking position can be increased, and there is a large difference in the position of the dispensing cap between the temporary position and the locking position, so that the locked state can be visually recognized at a glance. It is easy to judge, and by making the engagement part suddenly drop, it makes a snapping sound such as a clapper to improve the feeling of wearing, and it can be judged whether it is attached or detached acoustically, When the engaging part is engaged and disengaged, the downward pouring cap moves upward toward the temporary position when engaging and disengaging, so that the return movement (upward movement) when engaged and disengaged becomes smooth, and a feeling of popping out is further generated. Coupled with the half-lock prevention When the locking part is positioned at the lower end of the tapered peripheral surface immediately before the locking part falls into the engaging part, the inner peripheral surface below the locking part of the dispensing cap can be improved. By setting the spout to the outer peripheral surface shape where the abutting cap tilt preventing peripheral surface is connected to the lower end of the engaging portion (sagging peripheral surface), the prevention of half lock by preventing the tilting of the pouring cap is further strengthened. It becomes an extremely excellent liquid supply tank.

Further, in the invention described in claim 7 , the present invention can be realized with a simpler configuration, and in particular, a cap body having a locking portion that engages with and disengages from the engaging portion of the spout, and a push operation for interlocking the cap body. Separate parts from the cap outer periphery grip part provided with a part, and by assembling this, with parts and hands provided with a locking part that engages and disengages with the engaging part of the outer peripheral surface of the spout that may become dirty Because it is separated from the parts it has and it is assembled, there is no worry about getting your hands dirty, and the outer periphery of the cap outer periphery grip part is a push that interlocks the locking part as described above Since the operation part is provided and the part is not provided with the locking part, the cap body with the locking part is not easily damaged even if the outer cap outer periphery grip part is damaged, and the push operation part is damaged. Ensuring the locked state It is extremely soo the liquid supply tank because dispensing cap also protective effect hardly deviate from spout shocked and heat affected are exhibited.

Further, in the invention according to claim 8 , the protruding and retracting movement at the time of engagement and disengagement of the locking part is further improved, and even if foreign matter such as dust intervenes on the protruding and sliding movement surface of the locking part. It is easy to move, and it is excellent in durability.

According to a ninth aspect of the present invention, the upper surface of the coupling portion of the locking portion where the cam groove and the cam pin of the moving direction conversion coupling mechanism are slidably engaged and the interlocking transmission portion of the push operation portion. Since the position of the slide sliding surface with the lower surface is set above the upper end edge of the projecting port from which the inner end portion that engages with the engaging portion of the engaging portion projects, the slide is made via the projecting port. It is difficult for foreign matter to enter the sliding surface, and it is difficult for the moving direction conversion coupling mechanism to operate, so that the locking portion can be more smoothly projected and retracted, resulting in a liquid supply tank with excellent durability.

The invention according to claim 10 provides a cartridge-type oil supply tank that exhibits the above-described effects and is extremely practical.

Moreover, in invention of Claim 11 , it becomes liquid consumption apparatuses, such as an epoch-making combustion heater provided with the above-mentioned liquid supply tank.

  Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

As shown in FIGS. 1 to 4, after supplying the liquid into the tank body 1 from the spout 3 with the spout cap 2 removed, the spout cap 2 is fitted into the spout 3 and the shaft of the spout 3 is fitted. When pushed down in the direction, the inner end portions 5A of the plurality of locking portions 5 are moved together with the pouring cap 2 along the outer peripheral surface of the pouring port 3, and are locked when the pouring cap 2 is pushed down to the locking position. The inner end portion 5A of the locking portion 5 is automatically depressed and locked to the engaging portion 4 provided on the outer peripheral surface of the spout 3 by the locking biasing force of the biasing portion 6, for example. When the locking part 5 and the engaging part 4 are in a locked state, the pouring cap 2 is attached to the spout 3 in a retaining state.

  Conversely, when removing the dispensing cap 2 from the dispensing port 3, the locking mechanism 8 is released and the dispensing cap 2 is taken out from the dispensing port 3. The locking part 5 is moved in the sag direction against the locking bias and is disengaged from the engaging part 4.

  That is, when the pushing operation portion 7 provided on the outer peripheral surface of the pouring cap 2 is pushed inward with a finger of one hand, for example, the locking portion 5 is moved in the moving direction in conjunction with the movement direction changing coupling mechanism 14 described later. And the inner end portion 5A of the locking portion 5 moves in a direction in which the inner end portion 5A is moved away from the engaging portion 4 (against the protruding bias (locking bias) of the locking biasing portion 6). When it is moved) the lock is released.

  At this time, according to the present invention, the push operation part 7 is disposed in an exposed state on the outer peripheral surface of the plurality of the extraction caps 2 in the circumferential direction at an opposed state or at an interval, and only one push operation part 7 is pushed. One locking portion 5 that is interlocked with this does not move in the direction of movement from the engaging portion 4 to the position where it is disengaged, and at least one locking portion 5 is interlocked by the pressing of two or more push operation portions 7. Then, it moves in the retracting direction from the engaging portion 4 to the position where it is engaged / disengaged, and at least two locking portions 5 must be disengaged from the engaging portion 4 by the pushing of the two or more pushing operation portions 7. For example, the pouring cap 2 cannot be removed from the pouring port 3.

  Therefore, in the present invention, only the one-side engaging portion 5 is released by the pushing operation of the one-side pushing operation portion 7, and only one side is released so that the other half-locking in the locked state does not occur.

  That is, when only the push operation unit 7 on one side is pushed, or the push force of the finger is not equal, for example, the push operation unit 7 is pushed sufficiently with the index finger, and the push operation unit 7 is pushed with the thumb. As described above, if each locking operation unit 7 is configured so that one locking unit 5 is interlocked with one pressing operation unit 7 independently of each other as usual, the pressing operation unit 7 that has been sufficiently pressed as described above, Only the interlocking locking portion 5 is disengaged and the other locking portions 5 remain locked, and half-locking is easily caused. Since the dispensing cap 2 has a mounting clearance, it can be tilted slightly. In general, there is a mounting elasticity by packing etc. Unless the fingers are pushed in at the same time, an unstable state such as a half lock easily occurs.

  On the other hand, in the present invention, when one pushing operation portion 7 is pushed, not only one but also two or more locking portions 5 are interlocked with each other to move in the sunk direction. ) Is transmitted. In addition, the one locking portion 5 is configured to move in the sinking direction against the locking biasing force of the locking biasing portion 6 in conjunction with two or more push operation portions 7, and Even if one push operation part 7 is pushed, each latching part 5 does not move sufficiently (it does not move to the extent that it is disengaged from the engagement part 4), and when two or more push operation parts 7 are pushed. For the first time, each pushing force is transmitted to each locking portion 5 in cooperation with each other, and the locking portion 5 is configured to be disengaged from the engaging portion 4 for the first time.

  To repeat the description more easily, for example, the case where the push operation portion 7 is provided at two opposing positions as in the present embodiment described later, and the locking portion 5 is provided at two opposing positions so as to be adjacent thereto is also described. The two push operation parts 7 are sandwiched between the thumb and index finger of one hand and both are pushed in and taken out as they are. However, as usual, there is only one locking part 5 corresponding to one push operation part 7. In conjunction with this, it is configured such that when the push operation portion 7 is pushed, the corresponding locking portion 5 is moved in the moving direction through the moving direction conversion coupling mechanism 14 and is disengaged from the engaging portion 4. If only one side is pushed, or only one side is sufficiently pushed and the pushing force on the opposite side is insufficient, half-locking in which only the locking part 5 on one side is released easily occurs.

In contrast, in this embodiment, as shown in FIGS. 9 to 11, for example, one interlocking transmission on the side of the locking portion 5 provided in each locking portion 5 and each pressing operation portion 7 adjacent thereto. When the parts 11 are connected to each other by the moving direction conversion connecting mechanism 14 and one push operation part 7 is pushed, both of the adjacent locking parts 5 move in the sinking direction. Only when the pushing portions 7 are not moved sufficiently, the respective locking portions 5 do not move away from the engaging portions 4, and when both pushing operation portions 7 are pushed sufficiently at the same time, each of the locking portions 5 does not receive this force for the first time. It cooperates so as to assist, and it is configured to move sufficiently in the sinking direction and disengage from the engaging portion 4.

  Further, for example, as in the embodiments described later, the inner end portion 5A that is locked to the engaging portion 4 of the locking portion 5 has a lateral shape, and even if one of the push operation portions 7 is pushed, Only one side of the inner end 5A of the part 5 moves in the sinking direction as it is disengaged from the engaging part 4, but the opposite side is not yet detached from the engaging part 4 due to the lateral width, and the other pushing operation part 7 The force is transmitted evenly when the two are simultaneously pushed, and the opposite side of the inner end 5A is sufficiently moved in the sinking direction so that all parts of the inner end 5A are disengaged from the engaging portion 4 and are disengaged. You may comprise so that it may do.

  As described above, in the present invention, when the two or more push operation portions 7 are moved, the two or more locking portions 5 are disengaged and the locking portions 5 are disengaged from the engaging portion 4. That is, two or more locking portions 5 are moved in the direction of sag by one push operation portion 7 being pushed, and two or more push operation portions 7 are pushed against one lock portion 5. By constructing this to cooperate and move in the direction of sinking, there is a clearance for fitting the pouring cap 2 into the pouring port 3, and even if this clearance varies, half-locking occurs extremely. It is difficult to prevent half-locking, and the mounting performance is greatly improved.

As shown in FIGS. 5 to 7, for example, when the pouring cap 2 is attached, from the position of the straight drooping upper end peripheral surface 21 of the pouring port 3 where the pouring cap 2 is fitted and temporarily attached to the pouring port 3. The taper 3 is moved while the locking portion 5 is moved in the sinking direction against the locking urging force of the locking urging portion 6 along the tapered peripheral surface 22 where the outer peripheral surface of the spout 3 gradually increases in diameter. The engaging portion 5 is projectingly engaged (locked) by the protruding urging force of the locking urging portion 6 to the engaging portion 4 (falling peripheral surface) which is provided at the lower end of the peripheral surface 22 and is rapidly reduced in diameter. If the taper peripheral surface 22 is configured to be gently long, the tentative position where the spout cap 2 is fitted on the spout 3 and the locking position (lock position) locked to the engaging portion 4 are provided. As long as this becomes longer and clearer, the longer it is, the longer it can be visually confirmed whether it is locked or not. In addition, by increasing the amount of depression of the engaging portion 4, a locking sound such as a clapping sound (locking locking sound) sounds greatly, and the wearing feeling is also good, and it is easy to judge whether to attach or detach in terms of sound. It becomes.

  In addition, if configured in this way, as described above, it is difficult to release even by insufficient one-side pressing and it is difficult to be half-locked, so that the mounting performance is further improved, and for example, when mounting (in the locked state) If it is configured such that the urging force (returning urging force upward) is generated in the pouring cap 2 with respect to the spout 3 by the elastic force provided at the position of the pouring mechanism 10 (elastic force due to elastic contact by the packing or the like). Only when the pushing operation parts 7 are pushed sufficiently at the same time instead of one side, the respective locking parts 5 are disengaged from the engaging parts 4 at the same time, and as a result, the upper end is moved upward by the upward bias of the upper end. In addition, when the position of the maximum convex portion at the lower end of the tapered peripheral surface 22 is exceeded, the upward movement is promoted by the downward taper upward and the pressing force applied thereto by the locking urging portion 6, and the lifting is removed. Produces a clear pop-out feeling when removed It can be easily configured to be twisted.

  Specific embodiments of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 4, the pin-shaped portion 26, which is the valve-opening action portion described above in the conventional example, is inserted into the metal spout 3 projecting cylindrically from the metal tank body 1. A spout cap 2 provided with a spout mechanism 10 that opens the valve portion 27 inwardly against the spring bias is detachably fitted, and the spout 3 is abruptly attached to the outer peripheral surface of the spout 3. The engaging portion 4 provided on the entire circumference as a small-diameter portion that falls into the outer periphery and the protruding urging force of the locking urging portion 6 from the protruding port 15 on the inner peripheral surface of the dispensing cap 2 are projected and retracted. The engaging portion 4 is detachably engaged with the engaging portion 4 and in the locked state, the locking portion 5 keeps the dispensing cap 2 in a state of being prevented from coming off, and the locking portion 5 is urged in the protruding direction to be locked. The locking urging portion 6 to be urged, and the locking portion 5 is moved in the retracting direction against the locking urging force of the locking urging portion 6 to be locked with the engaging portion 4 Release A locking mechanism 8 comprising a pushing operation portion 7 provided on the outer peripheral surface of the pouring cap 2 to be fitted, and the pouring cap 2 is fitted on the pouring port 3 in the axial direction of the pouring port 3 By pushing down, when the locking portion 5 is urged by the locking urging portion 6, it moves along the outer peripheral surface of the spout 3 and reaches the engaging portion 4. The protrusion is biased so as to prevent it from coming off, and conversely, the pushing operation portion 7 provided on the outer peripheral surface of the spout 3 is pushed against the anti-contraction spring 28 to On the contrary, the locking portion 5 moves in the sinking direction, is disengaged from the engaging portion 4, and can be removed from the spout 3.

The locking portions 5 to be locked to the engaging portions 4 are not limited to two in the circumferential direction but are provided on the three or four extraction caps 2 at intervals, and the push operation portion 7 is also spaced. three there have not limited to two in the circumferential direction may be four provided. in this embodiment, the locking portion 5 is also pressed section 7 also distribution alternately in the circumferential direction is provided on the opposite condition two by two Then, each of them is connected so that the locking portion 5 is interlocked with the push of the push operation portion 7.

  That is, the push operation unit 7 is exposed on the outer peripheral surface of the dispensing cap 2 and provided in an opposed state, and the locking unit 5 is disposed in an opposed state so as to be disposed between the two push operation units 7. The dispensing cap 2 is provided so as to protrude inward from the inner peripheral surface.

  And it is comprised so that not only one latching part 5 but both latching parts 5 may move to a squeezing direction by the pushing of one pushing operation part 7, and only pushing of this one pushing operation part 7 is carried out. Then, any of the locking portions 5 that are linked to this does not move in the direction of sag until the position where the locking portions 5 are disengaged from the engaging portion 4, but each locking portion is moved when both the push operation portions 7 are pushed. The force (immersion power) for moving the locking portion 5 in the sinking direction due to this pushing motion is equally transmitted to each 5, and this is cooperated (added) with each locking portion 5 respectively. The stop portion 5 moves in the retracting direction so as to be disengaged from the engaging portion 4 for the first time by pressing both the pressing operation portions 7 at the same time, and both the locking portions 5 are moved to both the pressing operation portions 7. The extraction cap 2 cannot be pulled out from the outlet 3 unless it is disengaged from the engaging portion 4 by pushing.

More specifically, as shown in FIGS. 9 to 11, the interlocking transmission portion 11 that moves in accordance with the pushing operation of the push operation portion 7 is integrally formed on both the left and right sides of the push operation portion 7 for resin molding. The push operation portions 7 are supported by the anti-contraction springs 28, and the interlocking transmission portions 11 integrally formed on the left and right sides of the one push operation portion 7 are connected to the connecting portions 9 of the different locking portions 5. It is configured to be connected to one of the left and right, and to push the push operation portion 7 so that the driving force is transmitted to the left and right engaging portions 5 via the interlocking transmission portion 11, respectively. The linking transmission portions 11 on one side projecting from the different push operation portions 7 are connected to the connection portions 9 of the five.

  Accordingly, as described above, even when only one push operation portion 7 is pushed, the locking portion 5 is not disengaged from the engagement portion 4, and each push operation portion 7 is simultaneously pushed. This immersion power is transmitted via the interlocking transmission portion 11 so as to be combined with the respective locking portions 5, and both the locking portions 5 are engaged only when both pressing operation portions 7 are pushed simultaneously.
