Technical Field

The present invention relates to a water bottle cap, and more particularly to a water bottle cap with a pressure relief device.

Background

When an infant drinks water, the water bottle is mostly used in a way of sucking water by a suction pipe, and in order to meet the requirement that the infant can still drink water by lying on the back, an automatic suction pipe set is developed by manufacturers to be matched with the water bottle for use. Referring to fig. 1 and 2, the automatic straw set includes a suction nozzle 1, a connecting member 2, a hose 3 and a gravity ball 4, wherein the suction nozzle 1 is connected to the connecting member 2 in a sealing manner, the hose 3 is connected to a side of the connecting member 2 away from the suction nozzle 1, and the gravity ball 4 is connected to an end of the hose 3 away from the connecting member 2, so that when a baby sucks the suction nozzle 1, liquid (not shown) can enter the hose 3 through the gravity ball 4, and the gravity ball 4 pulls the hose 3 to move along with the liquid pulled by gravity along with the tilting or handstand of the kettle 5, thereby enabling the baby to suck the liquid in the kettle 5 at any angle.

The suction nozzle 1 of the kettle 5 is fixed on the kettle 5 by a bottle cap 6 to seal the kettle 5 so as to prevent liquid in the kettle 5 from leaking when pouring, and the suction nozzle 1 is provided with a sucking part 7, the tail end of the sucking part 7 is provided with an opening 8, and the opening 8 is communicated with the inside of the kettle 5; and one side of the bottle cap 6 is pivoted with a water bottle cap 9, the water bottle cap 9 can rotate relative to the bottle cap 6 and is buckled and fixed on the other side of the bottle cap 6 by a buckling switch 10, and meanwhile, the water bottle cap 9 can press the sucking part 7 to be bent to seal the opening 8. When the water bottle is to be used, the user presses the buckling switch 10, the buckling switch 10 will be inclined outward and will not buckle the water bottle cover 9, so that the water bottle cover 9 can be opened by the elasticity of the sucking part 7 for the infant to drink water.

However, because the inside of the kettle 5 is a closed space, when hot water is filled, the inside air expands due to heating and the pressure inside the kettle 5 is higher than the outside, so that when an unknown user presses the buckling switch 10 to open the kettle cover 9, the opening 8 of the sucking part 7 is not closed, and the liquid in the kettle 5 can be sprayed out from the opening 8 in a large amount like a fountain.

Since the liquid in the kettle 5 has a considerable temperature, the infant may be scalded, and once the clothes are wet, there is a risk of infection due to cold, which not only causes danger, but also causes environmental pollution, so the prior art needs to be improved urgently to meet the use requirement.

Disclosure of Invention

The invention mainly aims to solve the problem that liquid in a kettle in the prior art can be sprayed out from an opening of a sucking part.

The invention is a kettle cover with pressure relief device, which is mounted on a bottle mouth of a kettle and comprises a kettle suction nozzle, a bottle mouth cover, a fastener, an outer cover and an opening element, wherein the kettle suction nozzle is provided with a sucking part and a valve part, the valve part is provided with a pressure relief seam, the sucking part is used for sucking the liquid in the kettle, and the pressure relief seam is normally closed and opened when the valve part is deformed; the water bottle suction nozzle is arranged on the bottle mouth cover, the sucking part and the valve part are exposed towards the outer side, and the bottle mouth cover is locked on the bottle mouth so as to fix the water bottle suction nozzle on the bottle mouth.

The clamping piece is pivoted on the bottle mouth cover and integrally forms a traction element contacting the valve part; one end of the outer cover is pivoted on the bottle mouth cover, and the other end of the outer cover is buckled by the buckling piece and fixed on the other side of the bottle mouth cover; the opening element is arranged on the bottle mouth cover and is attached to the buckling piece, and the opening element can link the buckling piece to be outwards inclined without buckling the outer cover, so that the outer cover can be outwards turned by the elasticity of the sucking part; meanwhile, the traction element can drive the valve part to deform to open the pressure relief seam, and when the pressure relief seam is opened, pressure can be relieved from the pressure relief seam.

From the above description, it can be seen that the advantages of the present invention over the prior art include at least:

when a user presses the opening element to open the outer cover, the traction element can be used for opening the pressure relief seam to relieve pressure, so that the internal pressure and the external pressure tend to be consistent, the water in the kettle is prevented from being sprayed out from the sucking part due to the pressure, and the danger and the environmental pollution are avoided.

When the water kettle is used, the pressure relief seam is in a closed state normally, so that no matter the water kettle is used in a lying state or an inverted state, the pressure relief seam is in a closed state, and the problem of liquid leakage is avoided.

Detailed Description

The detailed description and technical contents of the present invention will now be described with reference to the drawings as follows:

referring to fig. 3A, 3B and 3C, the present invention is a water bottle cap with a pressure relief device, which is mounted on a bottle mouth 21 of a water bottle 20, and comprises a water bottle spout 30, a bottle cap 40, a fastener 50, an outer cap 60 and an opening element 70, wherein the water bottle spout 30 has a sucking portion 31 and a valve portion 32, the valve portion 32 is provided with a pressure relief seam 33, the sucking portion 31 is used for sucking the liquid in the water bottle 20, and the water bottle spout 30 is made of an elastic silica gel material; when the water bottle 20 is used, the pressure-release seam 33 is in a normally closed state, and when the valve part 32 is deformed, the pressure-release seam 33 is opened, and when the valve part 32 is not deformed, the pressure-release seam 33 is closed again; the relief seam 33 may be in the form of a straight line slit or a cross slit, or the like, and is depicted here as a straight line slit. The water bottle nozzle 30 is mounted on the bottle cap 40, and the sucking portion 31 and the valve portion 32 are exposed to the outside (as shown in fig. 3C), and the bottle cap 40 is locked on the bottle mouth 21, so as to fix the water bottle nozzle 30 on the bottle mouth 21, and to form a closed accommodating space inside the water bottle 20.

Referring to fig. 4 and 5A, the valve portion 32 may be a cylinder protruding upward, and the valve portion 32 is adjacent to the fastener 50; the fastener 50 is pivotally connected to a cylinder 42 of the bottleneck cover 40, and the fastener 50 integrally extends to form a circular pulling element 51, the pulling element 51 is sleeved on the cylindrical valve portion 32 by the circular shape, so that the pulling element 51 contacts the valve portion 32, and a flange 34 for clamping the pulling element 51 can further extend outwards from one side of the valve portion 32 away from the fastener 50, and by the clamping of the flange 34, the pulling element 51 (circular) can be prevented from separating from the valve portion 32 (cylindrical shape).

Referring to fig. 5B, one end of the outer cover 60 is pivoted to the bottleneck cover 40, and the other end is fastened by the fastener 50 and fixed to the other side of the bottleneck cover 40. The opening element 70 can slide relative to the fastener 50 to have a locking position (as shown in fig. 5A) and an unlocking position (as shown in fig. 5B), and the opening element 70 has a protrusion 71, the bottleneck cover 40 has a latch 41, when the opening element 70 is at the locking position, the protrusion 71 is exactly latched to the latch 41, so that the opening element 70 cannot tilt outwards, i.e. cannot drive the fastener 50 to tilt outwards.

Referring to fig. 5C, when the opening element 70 is located at the unlocking position (slides downward), the protrusion 71 and the latch 41 have a height difference, and the protrusion 71 does not abut against the latch 41, so that the opening element 70 can link the locking element 50 to rotate around the cylinder 42, and tilt outward relative to the bottleneck cover 40, so that the locking element 50 does not lock the outer cover 60, and the outer cover 60 can be opened outward by the elastic force of the sucking portion 31; meanwhile, the fastener 50 links the traction element 51 to drive the valve portion 32 to deform and open the pressure-releasing seam 33, and when the pressure-releasing seam 33 is opened, if the pressure of the kettle 20 is greater than the outside, the pressure can be released from the pressure-releasing seam 33, so that the gas 80 (indicated by a dotted line) in the kettle 20 is discharged from the pressure-releasing seam 33 (as shown in fig. 5C), and the internal and external pressures can be consistent.

Referring to fig. 6 and 7, another type of a spout 30A is shown, in which the sucking portion 31A of the spout 30A is separately provided, that is, the sucking portion 31A is an independent component, the spout 30A has a through hole 35, the sucking portion 31A has a ring groove 36 corresponding to the through hole 35, and the ring groove 36 is clamped on the through hole 35 to fix the sucking portion 31A on the spout 30A.

In summary, compared with the prior art, the invention has the following characteristics:

one, through the design that this traction element and this buckle spare are integrative, the user is pressing this buckle spare of this opening element interlock and when opening this enclosing cover, can this traction element of interlock drive this valve portion simultaneously warp, let this pressure release seam open and carry out the pressure release, let inside and outside pressure tend to unanimous, avoid the water in the kettle to spout from this portion of sucking because of pressure, avoid causing danger and environmental pollution.

When the valve part is not stressed, the pressure relief seam is of a closed structure in a normal state, so that the pressure relief seam is of a closed state when the water kettle is used no matter lying on back or standing upside down, and the problem of liquid leakage is avoided.

Thirdly, the valve part can be integrally formed when the kettle suction nozzle is manufactured, and the traction element can also be integrally formed when the fastener is manufactured, so that redundant working procedures can not be generated, and the manufacturing cost can be effectively reduced.

And fourthly, through the arrangement of the flange, the traction element (the circular ring) can be prevented from being separated from the valve part (the cylinder), so that the traction element can drive the valve part to deform, and the pressure relief seam can be opened really to relieve pressure.

And fifthly, a safety lock is formed by the design that the opening element is clamped against the clamping block of the bottle cap at the locking position, so that the opening element cannot incline outwards, and the problem of mistakenly opening the outer cover can be avoided.

Sixthly, when the user presses the opening element to link the buckle piece to rotate, the outer cover can be lifted outwards by virtue of the elasticity of the silica gel material of the sucking part, and the outer cover is synchronously opened.
