為讓本發明的上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

圖1是依照本發明一實施例所繪示的點火裝置剖面示意圖。請參照圖1，點火裝置100的整體外觀可例如是圓柱形或是方柱形，但不限於此。點火裝置100可包括蓋體120、電池容置部142以及點火部144。蓋體120具有開口端121，且蓋體120的內表面具有導電層122。電池容置部142用以裝設電池1421。電池容置部142具有第一電極EN1、第二電極EN2、第一導電接點EP1以及第二導電接點EP2。第一電極EN1及第二電極EN2分別用以電性連接電池1421的正極及負極。第一導電接點EP1及第二導電接點EP2設置在電池容置部142的第一端T1的外表面，其中電池容置部142的第一端T1用以套接蓋體120。第一導電接點EP1與第二導電接點EP2彼此電性絕緣。此外，第二電極EN2電性連接第二導電接點EP2。Fig. 1 is a schematic cross-sectional view of an ignition device according to an embodiment of the present invention. Please refer to FIG. 1, the overall appearance of the ignition device 100 may be, for example, a cylindrical shape or a square column shape, but is not limited thereto. The ignition device 100 may include a cover 120, a battery receiving portion 142 and an ignition portion 144. The cover 120 has an open end 121, and the inner surface of the cover 120 has a conductive layer 122. The battery accommodating portion 142 is used for accommodating a battery 1421. The battery accommodating portion 142 has a first electrode EN1, a second electrode EN2, a first conductive contact EP1, and a second conductive contact EP2. The first electrode EN1 and the second electrode EN2 are used to electrically connect the positive electrode and the negative electrode of the battery 1421, respectively. The first conductive contact EP1 and the second conductive contact EP2 are disposed on the outer surface of the first end T1 of the battery accommodating portion 142, wherein the first end T1 of the battery accommodating portion 142 is used to sleeve the cover 120. The first conductive contact EP1 and the second conductive contact EP2 are electrically insulated from each other. In addition, the second electrode EN2 is electrically connected to the second conductive contact EP2.

點火部144設置在電池容置部142的第二端T2(與第一端T1相對)。點火部144包括電熱元件1442，但不限於此。電熱元件1442的第一端H1電性連接第一電極EN1，且電熱元件1442的第二端H2透過導電線1441電性連接至第一導電接點EP1。The ignition part 144 is disposed at the second end T2 (opposite to the first end T1) of the battery receiving part 142. The ignition part 144 includes an electric heating element 1442, but is not limited thereto. The first end H1 of the heating element 1442 is electrically connected to the first electrode EN1, and the second end H2 of the heating element 1442 is electrically connected to the first conductive contact EP1 through the conductive wire 1441.

圖2是依照本發明一實施例所繪示的點火裝置的應用情境示意圖。請參照圖2，當蓋體120的開口端121套接在電池容置部142的第一端T1時，第一導電接點EP1可透過蓋體120之內表面的導電層122電性連接至第二導電接點EP2。如此一來，電熱元件1442、導電線1441、第一導電接點EP1、導電層122、第二導電接點EP2、第二電極EN2、電池1421、第一電極EN1將形成一封閉迴路而產生電流，致使電熱元件1442通電發熱而達到點火的目的。Fig. 2 is a schematic diagram of an application scenario of an ignition device according to an embodiment of the present invention. 2, when the open end 121 of the cover 120 is sleeved on the first end T1 of the battery accommodating portion 142, the first conductive contact EP1 can be electrically connected to the conductive layer 122 on the inner surface of the cover 120 The second conductive contact EP2. In this way, the heating element 1442, the conductive wire 1441, the first conductive contact EP1, the conductive layer 122, the second conductive contact EP2, the second electrode EN2, the battery 1421, and the first electrode EN1 will form a closed loop to generate current. , Causing the electric heating element 1442 to energize and generate heat to achieve the purpose of ignition.

另一方面，當蓋體120的開口121並未套接在電池容置部142的第一端T1時(如圖1所示)，或是當蓋體120是套接在點火部144時，由於第一導電接點EP1與第二導電接點EP2彼此電性絕緣，因此電熱元件1442的第一端H1與第二端H2之間形同斷路而無電流流通，因此電熱元件1442並不會發熱。On the other hand, when the opening 121 of the cover 120 is not sleeved on the first end T1 of the battery receiving portion 142 (as shown in FIG. 1), or when the cover 120 is sleeved on the ignition portion 144, Since the first conductive contact EP1 and the second conductive contact EP2 are electrically insulated from each other, the first end H1 and the second end H2 of the electric heating element 1442 are disconnected and no current flows. Therefore, the electric heating element 1442 does not fever.

可以理解的是，蓋體120必須套接在電池容置部142的第一端T1，以讓第一導電接點EP1電性連接第二導電接點EP2，方能使電熱元件1442通電發熱。因此，相較於現行採用掀蓋方式、滑蓋方式或是透過按壓按鍵的方式來點火的點火裝置，本實施例所提出的點火裝置100不會受到外力(例如碰撞或擠壓)而點火，大大提高點火裝置100的安全性。It is understandable that the cover 120 must be sleeved on the first end T1 of the battery accommodating portion 142 so that the first conductive contact EP1 is electrically connected to the second conductive contact EP2, so that the heating element 1442 can be energized and heated. Therefore, compared with the current ignition device that uses a flip-top method, a sliding-type method, or a method of pressing a button to ignite, the ignition device 100 proposed in this embodiment will not be ignited by external force (such as collision or squeeze). The safety of the ignition device 100 is greatly improved.

在本發明的一實施例中，電熱元件1442可例如是發熱絲，且發熱絲的形狀可例如是螺旋狀，但本發明不限於此。In an embodiment of the present invention, the heating element 1442 can be, for example, a heating wire, and the shape of the heating wire can be, for example, a spiral shape, but the invention is not limited thereto.

在本發明的一實施例中，點火部144還可包括陶瓷殼體1444。陶瓷殼體1444連接電池容置部142的第二端T2。陶瓷殼體1444具有開口端1445。電熱元件1442容置在陶瓷殼體1444內，且鄰近開口端1445。陶瓷殼體1444具有防熱保護功能，可避免使用者不小心碰觸到電熱元件1442而被燙傷。In an embodiment of the present invention, the ignition part 144 may further include a ceramic shell 1444. The ceramic shell 1444 is connected to the second end T2 of the battery receiving portion 142. The ceramic housing 1444 has an open end 1445. The electric heating element 1442 is contained in the ceramic casing 1444 and is adjacent to the open end 1445. The ceramic shell 1444 has a thermal protection function, which can prevent the user from accidentally touching the heating element 1442 and being burned.

在本發明的一實施例中，點火裝置100還可包括絕緣外殼體146。絕緣外殼體146用以包覆電池容置部142及部份的導電線1441，其中第一導電接點EP1及第二導電接點EP2(位於電池容置部142的第一端T1的外表面)與絕緣外殼體146之間具有間隙。因此，蓋體120可套接於此間隙中。也就是說，藉由將蓋體120的開口端121***此間隙，可讓蓋體120的開口端121穩定地套接在電池容置部142的第一端T1。另外，使用者只須將包覆在電池容置部142之外表面的絕緣外殼體146抽離，即可更換電池容置部142中的電池1421。In an embodiment of the present invention, the ignition device 100 may further include an insulating outer shell 146. The insulating housing 146 is used to cover the battery accommodating portion 142 and part of the conductive wires 1441, wherein the first conductive contact EP1 and the second conductive contact EP2 (located on the outer surface of the first end T1 of the battery accommodating portion 142) There is a gap between) and the insulating housing 146. Therefore, the cover 120 can be sleeved in this gap. In other words, by inserting the open end 121 of the cover 120 into the gap, the open end 121 of the cover 120 can be stably sleeved on the first end T1 of the battery receiving portion 142. In addition, the user only needs to remove the insulating outer shell 146 covering the outer surface of the battery accommodating portion 142 to replace the battery 1421 in the battery accommodating portion 142.

在本發明的一實施例中，蓋體120內表面的導電層122可例如是U形導電片或是導電環，而蓋體120的外表面可例如是絕緣體，但本發明不限於此。In an embodiment of the present invention, the conductive layer 122 on the inner surface of the cover 120 may be, for example, a U-shaped conductive sheet or a conductive ring, and the outer surface of the cover 120 may be, for example, an insulator, but the present invention is not limited thereto.

圖3是依照本發明另一實施例所繪示的點火裝置剖面示意圖。請合併參照圖1及圖3。圖3的點火裝置100’類似於圖1的點火裝置100，兩者的差異僅在於，點火裝置100’的點火部144’還包括過溫度保護元件1443。過溫度保護元件1443耦接在電熱元件1442的第一端H1與第一電極EN1之間，用以對電熱元件1442進行過溫度保護。3 is a schematic cross-sectional view of an ignition device according to another embodiment of the invention. Please refer to Figure 1 and Figure 3 together. The ignition device 100' of FIG. 3 is similar to the ignition device 100 of FIG. 1, and the difference between the two is only that the ignition portion 144' of the ignition device 100' also includes an over-temperature protection element 1443. The over-temperature protection element 1443 is coupled between the first end H1 of the electric heating element 1442 and the first electrode EN1 for over-temperature protection of the electric heating element 1442.

更進一步來說，在電熱元件1442通電發熱的情況下，當電熱元件1442的溫度值大於或等於一臨界值時，過溫度保護元件1443可反應於高溫而斷開電熱元件1442的第一端H1與第一電極EN1之間的電流路徑，從而讓電熱元件1442斷電降溫。相對地，當電熱元件1442的溫度值小於上述臨界值時，過溫度保護元件1443可導通電熱元件1442的第一端H1與第一電極EN1之間的電流路徑，以讓電熱元件1442通電發熱。Furthermore, when the heating element 1442 is energized to generate heat, when the temperature value of the heating element 1442 is greater than or equal to a critical value, the over-temperature protection element 1443 can respond to the high temperature and disconnect the first end H1 of the heating element 1442 The current path between the first electrode EN1 and the first electrode EN1, so that the heating element 1442 is de-energized and cooled. In contrast, when the temperature value of the heating element 1442 is less than the above-mentioned critical value, the over-temperature protection element 1443 can conduct the current path between the first end H1 of the heating element 1442 and the first electrode EN1, so that the heating element 1442 is energized and generates heat.

在本發明的一實施例中，過溫度保護元件1443可採用具有正溫度係數(Positive Temperature Coefficient，PTC)特性的熱敏電阻(Thermistor)來實現，但本發明不限於此。In an embodiment of the present invention, the over-temperature protection element 1443 may be implemented by a thermistor with a positive temperature coefficient (PTC) characteristic, but the present invention is not limited to this.

另外，關於圖3的點火裝置100’的其他實施細節及運作，可參酌上述圖1及圖2的相關說明，在此不再贅述。In addition, for other implementation details and operations of the ignition device 100' of FIG. 3, reference may be made to the related descriptions of FIGS. 1 and 2, which will not be repeated here.

綜上所述，本發明實施例所提出的點火裝置，其蓋體須套接在電池容置部的第一端，以讓第一導電接點電性連接第二導電接點，方能使電熱元件通電發熱而達到點火的目的。因此，相較於現行採用掀蓋方式、滑蓋方式或是透過按壓按鍵的方式來點火的點火裝置，本發明實施例的點火裝置不會受到外力碰撞或擠壓而點火，大大提高點火裝置的安全性。To sum up, in the ignition device proposed in the embodiment of the present invention, the cover body must be sleeved on the first end of the battery accommodating part, so that the first conductive contact is electrically connected to the second conductive contact. The electric heating element is energized and generates heat to achieve the purpose of ignition. Therefore, compared with the current ignition device that uses a flip lid method, a sliding lid method, or a method of pressing a button to ignite, the ignition device of the embodiment of the present invention will not be ignited by external force collision or compression, which greatly improves the performance of the ignition device. safety.

雖然本發明已以實施例揭露如上，然其並非用以限定本發明，任何所屬技術領域中具有通常知識者，在不脫離本發明的精神和範圍內，當可作些許的更動與潤飾，故本發明的保護範圍當視後附的申請專利範圍所界定者為準。Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention.
