Abstract

The utility model discloses a one-off lighter with safeguard function, which comprises a lighter body filling fuel and a lighter head to light. The lighter head is provided with a bridge plate where fuel is released by press; at the bottom of the bridge plate, a bolt is linked, and a safeguard device is arranged on the lighter body to stop or allow the bolt moving up and down. Because of the safeguard device, if the bolt of bridge plate is allowed to move downward, flame can be lighted by press, and if that is stopped, flame will not be lighted by press.

Description

Disposable lighter with function of safety protection

Technical field

The utility model relates to lighter, relates in particular to a kind of disposable lighter with function of safety protection.

Background technology

General known disposable lighter mean pocket lighter, and fuselage is that resin materials such as AS, ABS, PS are made.Disposable gas lighter is available in a variety of forms, and the common structure of various disposable lighters has: casing, fan housing, igniter (finished product head), gas operated device etc. produce gas-flow and light under the acting in conjunction of these structures.For example: adopt the lighter of traditional spark wheel to require the user facing to toothed spark wheel of a flint rotation, so that produce spark, the user depresses the startup plate subsequently, goes into out gas and produces flame; The another kind of igniter that is used for disposable lighter adopts a common igniter, so that light gaseous fuel, because the user starts plate and makes fuel begin to flow firmly to pressing down, also begins ignition process.

The safety design relevant with disposable lighter (promptly having the safety precaution design that prevents that children from playing and catching fire) has such as following previous patent: announce No. 579413 " having the lighter that the deflection door lock prevents that child from using ", announce No. 568247 " structure of lighter safety ", announce No. 542332 by " safety device of lighter and anti-children's use ", announce No. 442637 in " lighter security architecture device ", announce No. 422309 " the safety improved structure of simple type lighter ", announce No. 339148 " safety mechanism for lighter of improvement ", announce No. 328824 " safety lighter of avoiding the child to use ", announce No. 324513 " simple type safety lighter ", announce No. 265840 " preventing the safety lighter that the child uses " ... or the like.Various safeguard constructions have increased difficulty that is not intended to the operator or the difficulty of being operated by unexpected user, simultaneously, for the user's of operation of having a mind to and expection operation to user's good will.But the above-mentioned disposable lighter complex structure that has increased safeguard construction, operation inconvenience and cost are higher.

Summary of the invention

At the shortcoming of prior art, the purpose of this utility model provides a kind of disposable lighter with function of safety protection, and it is simple in structure, easy to operate and with low cost.

To achieve these goals, the technical solution of the utility model is: a kind of disposable lighter with function of safety protection, comprise fuselage that fuel is housed and the head that is used to light a fire, on described head, be provided with and press down and emit the bridge plate of fuel, below described bridge plate, be connected with a pin member, the corresponding protector that can stop or allow described pin member to move downward that is provided with on described fuselage.

Described protector is a removable plane shell fragment, and being provided with in this plane shell fragment can be for the recess of described pin member insertion.

The described pin member of the relative aperture of described recess is big 2 to 3 millimeters.

Described plane shell fragment connects with a V-type shell fragment, and this V-type shell fragment is limited to be placed in the chamber of fuselage.

The angular range of described V-type shell fragment is spent less than 90 greater than 30 degree.

Compared with prior art, the utility model is the corresponding protector that can stop or allow described pin member to move downward that is provided with on fuselage, when protector allows the pin member of bridge plate to move downward, can press down and starting ignition, when protector stops that the pin member of bridge plate moves downward, can not press down and light a fire.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

The specific embodiment

See also Fig. 1, Fig. 2 and Fig. 3, the disposable lighter with function of safety protection of the present utility model comprises fuselage 1 that fuel is housed and the head 2 that is used to light a fire.On head 1, be provided with the fan housing 101, the flame adjusting ring 102 that is used to regulate the gas-flow size that are used to keep out the wind, be used for, can press down the face valve of opening fuselage and emit the bridge plate 104 of fuel, below bridge plate 104, be connected with pin member 105 with the emery wheel 103 of flint friction; The corresponding protector that can stop or allow pin member to move downward that is provided with on fuselage 2, this protector is a removable plane shell fragment 201, being provided with in this plane shell fragment 201 can be for the recess 202 of pin member insertion, the relative aperture pin member 105 of recess 202 is big 2 to 3 millimeters, plane shell fragment 201 connects with V-type shell fragment 203, this V-type shell fragment 203 is limited to be placed in the chamber 204 of fuselage 2, the angular range of V-type shell fragment 203 less than 90 degree, is provided with the face valve 205 that is used to seal combustion gas greater than 30 degree in fuselage 2, the drainage core 207 that is connected with face valve 205 by core retainer plate 206.

Removable plane shell fragment 201 is moved forward, and its recess 202 just in time coincide with the pin member 105 of bridge plate 104, and bridge plate 104 can the starting ignition to pressing down; When pin member 105 was in the inoperative position, it withstood on shell fragment 201 bodies of removable plane, made the limitation of movement system of bridge plate 104.V-type shell fragment 203 integrally forms a spring function with removable plane shell fragment 201, V-arrangement shell fragment 203 is upheld automatically backward after once lighting a fire, making removable plane shell fragment 201 move synchronously resets, lighter is set back be in a safe condition, igniting then need repeat above action if need once more.

The utlity model has following effect:

1, can not changing fully under the prerequisite of original simple lighter structure, obviously strengthen lighter The security protection effect.

2, additional simple components and parts can reach the purpose that safety switch is set.

3, easy to operate.

4, with low cost.

5, the generation of accident in the time of preventing effectively that children from playing.

6, can effectively prevent in handling process or be placed in the pocket, the bridge plate pressing plate be at improper pressurized The time, the generation danger that butane gas is excessive.

7, practical, economical, can be used in practice and promote fully.
