Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted cigarette lighters, in particular to an anti-scalding vehicle-mounted cigarette lighter structure. Background Art

[0002] The cigarette lighter is a device in the car. The traditional cigarette lighter draws power from the car power supply to heat the metal heating plate or metal heating wire and other electric heating units to provide a source of ignition for the cigarette. With the development of automobiles and the continuous changes in people's needs, the cigarette lighter interface can usually be equipped with an on-board inverter to charge mobile electronic devices. The elastic head in the middle of the interface is the positive pole, and the buckles on both sides are the negative pole. The power supply is directly connected to the car battery, and the current power is the same as the battery.

[0003] The Chinese utility model patent with the authorization announcement number "CN209371306U" is specifically a "vehicle anti-scalding cigarette lighter". It uses inner and outer iron shells to form a double iron shell form to prevent overheating and ensure the safety of surrounding electronic components.

[0004] Although the above device can prevent smokers from getting burned when holding the cigarette lighter, the cigarette lighter butt is located at the end of the cigarette lighter. When the smoker takes the cigarette lighter out of the vehicle body to light a cigarette and reinserts it into the vehicle body after lighting the cigarette, the cigarette butt at the end of the cigarette lighter is close to the cigarette lighter and is heated to a high temperature and red state. Therefore, it is easy to touch the skin and cause burns to the smoker, resulting in poor anti-scalding performance. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides an anti-scalding vehicle-mounted cigarette lighter structure, which can effectively solve the problems raised in the background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides an anti-scalding vehicle-mounted cigarette lighter structure, comprising a shell, wherein both ends of the shell are penetrated with movable cavities, a cigarette lighter butt that can extend out of the shell is slidably installed in the movable cavity, a positioning component comprises a threaded ring installed with an inner cavity wall of the movable cavity, and also comprises a fixing ring arranged below the threaded ring and fixedly installed on the inner cavity wall of the movable cavity, a telescopic component is arranged in the movable cavity and rotatably installed at the bottom of the cigarette lighter butt, and a threaded round block that can be threadedly connected with the threaded ring, an extrusion rod that penetrates the fixing ring and extends out of the movable cavity is fixedly installed at the bottom of the threaded round block away from the cigarette lighter butt, and a spring is sheathed on the extrusion rod and fixedly installed at the bottom of the threaded round block and contacts with the top of the fixing ring.

[0008] Furthermore, a clamping block is fixedly mounted on the top of the shell, a cigarette lighter port communicating with the active cavity is penetrated through the clamping block, and a gasket is fixedly sleeved on the outer ring wall of the shell.

[0009] Furthermore, a connecting ring is provided below the gasket and is fixedly sleeved on the outer ring wall of the shell and flush with the bottom end of the shell. Two lifting blocks are symmetrically fixedly installed on the outer ring wall of the connecting ring.

[0010] Furthermore, a connecting column which is telescopically and slidably installed in the movable cavity is installed at the bottom of the cigarette lighter, and a limiting ring is fixedly installed on the connecting column away from the bottom of the cigarette lighter.

[0011] Furthermore, a knob arranged below the connecting ring is fixedly mounted on the bottom end of the extrusion rod.

[0012] Furthermore, a limiting groove is provided at the top of the threaded round block to facilitate the limiting rotation of the limiting ring, and the connecting column is rotatably mounted with the threaded round block through the limiting groove and the limiting ring.

[0013] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] 1. A retractable and sliding cigarette lighter is provided in the housing. When the cigarette lighter is removed from the vehicle body to light a cigarette, and when it needs to be reinserted into the vehicle body after the cigarette is lit, the cigarette lighter is automatically retracted into the housing through the built-in spring structure. During the entire cigarette lighting process, the cigarette lighter is extended only when the smoker takes the cigarette lighter out of the vehicle body and puts the cigarette at the cigarette lighter. This greatly avoids the possibility of the cigarette lighter causing burns to the smoker during the movement.

[0015] 2. In order not to affect the heating and fixation of the cigarette lighter when it is inserted into the cigarette lighter hole of the vehicle body, a threaded ring is set in the shell, and a threaded round block that can be threadedly connected with the threaded ring is installed on the telescopic structure of the cigarette lighter. Under the premise of not affecting the telescopic characteristics of the cigarette lighter, the stability of the cigarette lighter when being heated is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model is further described below in conjunction with embodiments.

[0027] Example 1

[0028] Reference Figure 1-4, which is the first embodiment of the utility model, discloses a scalding-proof vehicle-mounted cigarette lighter structure, including a shell 1, with active cavities 11 extending through both ends of the shell 1, a cigarette lighter head 2 that can extend out of the shell 1 is slidably installed in the active cavity 11, the cigarette lighter head 2 includes an electrode sheet in contact with the positive and negative electrodes inside the cigarette lighter hole, and also includes a resistance heating wire connected to the electrode sheet, and the cigarette is lit by supplying power to the resistance heating wire to generate heat, the positioning component includes a threaded ring 12 installed on the inner wall of the active cavity 11, and also includes a fixing ring 13 arranged below the threaded ring 12 and fixedly installed on the inner wall of the active cavity 11, and the telescopic component is arranged in the active cavity 11 A threaded round block 31 is rotatably mounted on the bottom of the cigarette lighter 2 and can be threadedly connected to the threaded ring 12. A squeezing rod 32 is fixedly mounted on the bottom of the threaded round block 31 away from the cigarette lighter 2, which penetrates the fixing ring 13 and extends out of the movable cavity 11. The squeezing rod 32 is sheathed with a spring 33 fixedly mounted on the bottom of the threaded round block 31 and in conflict with the top of the fixing ring 13. The elastic restoring force provided by the spring 33 can automatically retract the hot and red cigarette lighter 2 into the housing 1 without external interference, so as to prevent the cigarette lighter 2 from always being located at the end of the cigarette lighter and scalding the smoker when the cigarette lighter is taken out and put into the vehicle body.

[0029] Example 2

[0030] Reference Figure 1-4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: a clamping block 14 is fixedly installed on the top of the shell 1. The clamping block 14 is designed with an arc-shaped profile, which is convenient for the cigarette lighter 2 to be ejected from the cigarette lighter hole of the vehicle body along with the shell 1 after being heated to a certain temperature, but it will not be completely ejected. A cigarette lighter port connected to the active cavity 11 is opened through the clamping block 14. A gasket 15 is fixedly sleeved on the outer ring wall of the shell 1, which conflicts with the vehicle body 1, so that the connecting ring 16 is always exposed, which is convenient for the disassembly and assembly of the shell 1. A connecting ring 16 is fixedly sleeved on the outer ring wall of the shell 1 and is flush with the bottom end of the shell 1. The outer surface of the connecting ring 16 is fixedly sleeved on the outer ring wall of the shell 1 and is flush with the bottom end of the shell 1. Two lifting blocks 17 are symmetrically fixedly installed on the ring wall, and a connecting column 21 is installed at the bottom of the cigarette lighter 2 and is telescopically and slidably installed in the movable cavity 11. A limiting ring 22 is fixedly installed at the bottom of the connecting column 21 away from the cigarette lighter 2, and a knob 35 arranged below the connecting ring 16 is fixedly installed at the bottom end of the extrusion rod 32. The knob 35 can be rotated and can also be telescopically pressed. A limiting groove 34 is provided at the top of the threaded block 31 for facilitating the limiting rotation of the limiting ring 22. The connecting column 21 is rotatably installed with the threaded block 31 through the limiting groove 34 and the limiting ring 22, so that the rotation of the threaded block 31 will not drive the cigarette lighter 2 to rotate, so that the cigarette lighter 2 can be aligned and contacted with the cigarette lighter port of the vehicle body.

[0031] The remaining structures are the same as those of Example 1.

[0032] The workflow of this utility model is as follows:

[0033] First, insert the shell 1 as a whole into the cigarette lighter hole of the vehicle body, and press it down hard, so that the compression spring in the cigarette lighter hole of the vehicle body is inserted into the connection between the clamping block 14 and the shell 1, so that the shell 1 as a whole remains fixed. At this time, the threaded round block 31 in the shell 1 is threadedly installed on the threaded ring 12 in the active cavity 11, so the cigarette lighter head 2 is located at the cavity opening of the active cavity 11 and contacts the positive and negative electrodes in the cigarette lighter hole to form a power supply path to heat the main resistance wire of the cigarette lighter head 2. When heated to a certain degree, the temperature sensor in the cigarette lighter hole detects that the temperature signal is good, and feeds it back to the vehicle body, and starts the pusher assembly in the cigarette lighter hole through the vehicle body, so that the shell 1 is ejected from the cigarette lighter hole, and the locking state of the compression spring and the clamping block 14 is released;

[0034] Secondly, at this time, the smoker holds the two lifting blocks 17 to hold the main body of the shell 1, and drives the threaded round block 31 to rotate by rotating the knob 35, thereby releasing the threaded locking state with the threaded ring 12. At this time, the spring 33 that was originally elastically stretched begins to elastically recover, and pulls the threaded round block 31 to move toward the end of the shell 1 close to the connecting ring 16, and synchronously brings the cigarette lighter 2 into the active cavity 11 through the connecting column 21. When the smoker aligns the cigarette with the cigarette lighter port of the clamping block 14, by pressing the knob 35, the threaded round block 31 is pushed. At this time, the spring 33 is forced to stretch again, and the cigarette lighter 2 is forced to approach the cigarette lighter port, so that the temperature at the cigarette lighter port increases, and the cigarette is lit;

[0035] Finally, after lighting the cigarette, release the knob 35, and retract the cigarette lighter 2 again through the elastic recovery of the spring 33, and then insert the shell 1 as a whole into the cigarette lighting hole of the vehicle body. During the entire cigarette lighting process, the heated and red cigarette lighter 2 is always inside the shell, and only when the cigarette is close to the cigarette lighting port will it extend into the cigarette lighting port, which greatly avoids the cigarette lighter 2 of the cigarette lighter from causing burns to the smoker during the movement.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
