Description

Technical Field

[0001] The utility model belongs to the technical field of electronic cigarette accessories, and particularly relates to a spring needle for electronic cigarettes. Background Art

[0002] The important components of electronic cigarettes are the cigarette rod and the cigarette cartridge. Common electronic cigarette cartridges include a mouthpiece, a liquid storage chamber, an atomizer, etc. The cigarette rod includes an indicator light, a battery, an integrated control circuit, and a pneumatic sensor switch. The battery in the cigarette rod can power the atomizer in the cigarette cartridge. Generally, the current is connected by the spring needle installed on the cigarette rod and the contact point installed on the cigarette cartridge atomizer. The spring needle is also called a spring needle or a spring ejector. It is composed of three basic components: a needle shaft, a spring, and a needle tube. However, the current spring needles for electronic cigarettes still have the following disadvantages in actual use:

[0003] 1. When using an electronic cigarette, the oil in the cartridge often enters the needle tube of the cartridge needle in large quantities, soaking the inner cavity of the needle tube with oil, wrapping the spring with oil, and the viscous oil will weaken the elasticity of the spring. The oil wrapping the spring may even dry up and solidify over time, making the spring completely ineffective and making the cigarette rod unable to normally power the cartridge atomizer.

[0004] 2. The outer wall of the needle tube of the existing electronic cigarette cartridge is generally smooth, and is generally installed on the cigarette rod by plugging. Long-term and frequent use will cause the position of the cartridge to loosen, resulting in poor contact between the cartridge and the contact point on the cartridge atomizer.

[0005] Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems. Utility Model Content

[0006] The utility model aims to provide a spring needle for electronic cigarettes, which squeezes the tobacco oil collected in the extrusion groove out of the extrusion hole through an upwardly moving annular extrusion plate, and at the same time, the inclined setting of the extrusion hole can prevent the tobacco oil on the side wall of the shell from entering the extrusion groove again from the extrusion hole, and blocks the tobacco oil entering the sealing groove through the precise fit between the rubber sealing ring and the sealing groove when the needle head is squeezed, thereby solving the problem that the tobacco oil in the tobacco cartridge of the existing electronic cigarette often enters the spring groove in large quantities when in use, causing the spring to fail.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model discloses a spring needle for electronic cigarette, comprising a shell, a needle shaft is slidably connected inside the shell, a needle head is fixedly installed on the upper end of the outer wall of the needle shaft, a spring groove is opened at the lower end inside the shell, an annular connecting plate is fixedly installed on the side wall of the needle shaft and located inside the spring groove, a spring is fixedly installed between the lower end of the outer wall of the annular connecting plate and the lower end of the inner wall of the spring groove, an extrusion groove is opened at the upper end inside the shell, an annular extrusion plate is fixedly installed on the side wall of the needle shaft and located inside the extrusion groove, and extrusion holes that penetrate the upper end of the inner side wall of the extrusion groove are opened on the upper end of the side wall of the shell in a circumferential arrangement.

[0009] Furthermore, all the extrusion holes are arranged obliquely, and the hole position of each extrusion hole located outside the shell is lower than the hole position located on the inner wall of the extrusion groove.

[0010] Furthermore, a connecting block is fixedly installed at the middle part of the lower end of the outer wall of the annular connecting plate, and the connecting block is inserted into the interior of the spring.

[0011] Furthermore, a sealing groove is opened in the middle end of the shell, an annular circular groove is opened at the lower end of the inner wall of the sealing groove, an intermediate connecting piece is fixedly installed on the side wall of the needle shaft and inside the sealing groove, and a rubber sealing ring is fixedly installed on the outer wall of the intermediate connecting piece.

[0012] Furthermore, the rubber sealing ring is precisely fitted to the inner side wall of the sealing groove, and the rubber sealing ring and the annular circular groove are fitted to each other.

[0013] Furthermore, an insulating fixing sleeve is fixedly installed on the lower end of the shell side wall.

[0014] Furthermore, a connecting seat is fixedly installed on the lower end of the outer wall of the shell.

[0015] The utility model has the following beneficial effects:

[0016] 1. When the utility model is in use, when the user pulls out the cigarette cartridge, the upwardly moving annular extrusion plate will squeeze the smoke oil collected in the extrusion groove out of the extrusion hole, and at the same time, the inclined setting of the extrusion hole can prevent the smoke oil on the side wall of the shell from entering the extrusion groove again from the extrusion hole, and the smoke oil entering the sealing groove is blocked by the precise fit between the rubber sealing ring and the sealing groove when the needle is squeezed, preventing it from entering the spring groove below, thereby greatly reducing the amount of smoke oil entering the spring groove, increasing the service life of the spring, and reducing the failure rate when the cigarette rod is in use.

[0017] 2. When the utility model is in use, the insulating fixing sleeve can improve the installation connection strength when the shell is installed on the cigarette rod, so that after the cigarette rod of the electronic cigarette is used for a long time, the shell on it can still maintain the installation stability, reducing the probability of poor contact between the needle and the contacts on the cigarette cartridge atomizer.

All the extrusion holes 420 are arranged at an angle. The hole position of each extrusion hole 420 located on the outside of the shell 100 is lower than the hole position located on the inner wall of the extrusion groove 400. When the smoke oil in the electronic cigarette flows into the shell 100 from the upper end of the shell 100 during use, it will first enter the extrusion groove 400. The extrusion groove 400 can collect the smoke oil entering the shell 100. When the user pulls out the cigarette cartridge, the top of the needle 120 loses the squeeze. At this time, the needle shaft 110 will drive the annular extrusion plate 410 to move upward, and the upward moving annular extrusion plate 410 will squeeze the smoke oil collected in the extrusion groove 400 out from the extrusion hole 420.

[0028] Among them Figure 3-5 As shown, a connecting block 230 is fixedly installed in the middle of the lower end of the outer wall of the annular connecting plate 210 , and the connecting block 230 is inserted into the spring 220 . The connecting block 230 can strengthen the connection strength between the spring 220 and the annular connecting plate 210 .

[0029] Among them Figure 3-5 As shown, a sealing groove 300 is provided at the middle end of the shell 100, an annular groove 310 is provided at the lower end of the inner wall of the sealing groove 300, an intermediate connecting piece 320 is fixedly installed on the side wall of the needle shaft 110 and located inside the sealing groove 300, and a rubber sealing ring 330 is fixedly installed on the outer wall of the intermediate connecting piece 320, and the rubber sealing ring 330 is precisely fitted with the inner side wall of the sealing groove 300, and the smoke oil entering the sealing groove 300 is blocked by the precise fit between the rubber sealing ring 330 and the sealing groove 300, and the rubber sealing ring 330 and the annular groove 310 fit each other, and when the needle 120 moves downward under pressure, the needle shaft 110 will drive the rubber sealing ring 330 to move downward and contact and squeeze the annular groove 310, so as to seal the lower end of the inner wall of the sealing groove 300.

[0030] Among them Figure 1 , Figure 2 and Figure 5As shown, an insulating fixing sleeve 500 is fixedly installed at the lower end of the side wall of the housing 100, and the insulating fixing sleeve 500 can improve the installation connection strength when the housing 100 is installed on the cigarette rod;

[0031] A connection base 600 is fixedly mounted on the lower end of the outer wall of the housing 100 , and the connection base 600 is used to be electrically connected to the PCB board in the cigarette rod.

[0032] A specific application of this embodiment is: when in use, the device drives the needle 120 at the upper end of the outer wall of the needle shaft 110 to contact the contact on the cartridge atomizer through the spring 220 to power the cartridge atomizer. When the smoke oil in the electronic cigarette flows from the upper end of the shell 100 into the shell 100 during use, it will first enter the extrusion groove 400, and the extrusion groove 400 can collect the smoke oil entering the shell 100. When the user pulls out the cigarette cartridge, the upper part of the needle 120 loses the squeeze. At this time, the needle shaft 110 will drive the annular extrusion plate 410 to move upward, and the upwardly moving annular extrusion plate 410 will extrude the oil in the groove 400. The collected smoke oil is squeezed out from the extrusion hole 420. At the same time, the inclined setting of the extrusion hole 420 can prevent the smoke oil on the side wall of the shell 100 from entering the extrusion groove 400 again through the extrusion hole 420. At the same time, the precise fit between the rubber sealing ring 330 and the sealing groove 300 blocks the smoke oil entering the sealing groove 300 and prevents it from entering the spring groove 200 below. When the needle 120 moves downward under pressure, the needle shaft 110 drives the rubber sealing ring 330 to move downward and contact and extrude with the annular groove 310, thereby sealing the lower end of the inner wall of the sealing groove 300, thereby further improving the sealing effect of the sealing groove 300.
