[0021] The terms used in this utility model are for the purpose of describing specific embodiments only and are not intended to limit the utility model. For example, the terms "upper," "lower," "front," and "rear" used below to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are used only to facilitate the description of the utility model and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation. Therefore, they should not be understood as limiting the utility model.

[0022] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0023] Nail guns, an indispensable tool in fields such as construction, carpentry, and renovation, rapidly drive nails into various materials by driving a firing pin, significantly improving construction efficiency. However, during actual operation, users adopt various nailing postures, and hard objects or debris such as dust, sand, and nail fragments in the construction environment can easily enter the gun through the nozzle, causing nail jams or other dangerous operations. Furthermore, if the firing pin is affected by the user's unique nailing posture or by debris during operation, it is very likely to interfere with its normal motion trajectory, causing deviations. This not only affects nailing accuracy and efficiency, but can also cause mechanical failures or even safety accidents, threatening the operator's safety.

[0024] Based on this, the present invention provides a striker device that is conducive to clearing debris from the striker channel and can improve the stability of the striker. The striker device provided in this application can be applied to any device equipped with a striker, such as a nail gun, a glue dispenser, etc. This application does not limit the equipment to which the striker device is applied.

[0025] See also Figure 1 , Figure 1 This is a schematic diagram of a first state of a striker device 100 according to an embodiment of the present invention. The striker device 100 of the present invention can achieve a specific mechanical action by striking or pushing other mechanical components.

[0026] The firing pin assembly 100 includes an energy release module 101 , a firing pin 102 and a barrel 103 .

[0027] The energy release module 101 is used to release accumulated energy to propel the striker 102 to slide. In some embodiments, the energy release module 101 can store energy in a first state and release energy in a second state. In some embodiments, the energy release module 101 includes a pusher 1011. One end of the pusher 1011 is connected to the striker 102. When the pusher 1011 moves in a first direction driven by the striker 102 to store energy, the energy release module 101 is in the first state. When the pusher 1011 drives the striker 102 in a second direction to convert the stored energy into mechanical energy, the energy release module 101 is in the second state. This application does not limit the specific design or propulsion method of the pusher 1011. For example, in some embodiments, the energy release module 101 also includes a cylinder 1012. In this case, the pusher 1011 can be a piston, and the striker 102 can serve as the piston rod. When the pusher 1011 moves in the first direction driven by the striker 102, it can compress the gas or liquid within the cylinder 1012 to store energy. The air pressure or hydraulic pressure within the cylinder 1012 can push the pusher 1011, thereby moving the striker 102 in the second direction. In other embodiments, the pusher 1011 can also be a spring. When the pusher 1011 is a spring, the energy release module 101 can be provided with the cylinder 1012 or not.

[0028] The barrel 103 is provided with a firing pin passage 1031 extending from front to back. This passage is used to accommodate the firing pin 102, which slides within the passage. The firing pin passage 1031 is also provided with a dust removal outlet 1032, which communicates with the outside. This allows debris within the firing pin passage 1031 to be discharged through the dust removal outlet 1032. In one embodiment, the dust removal outlet 1032 is located on the side of the firing pin passage 1031 that faces downward during use. This facilitates the complete removal of hard objects or debris, such as dust, sand, and nail fragments, from the firing pin passage 1031, reducing the likelihood of debris remaining in the passage 1031 and ensuring the safe use of the firing pin device 100.

[0029] The striker 102 is used to strike or push other mechanical components. One end of the striker 102 is connected to the pusher 1011 of the energy release module 101, while the other end is used to strike or push other mechanical components, such as a nail. The striker 102 is provided with a plurality of teeth 1021 and a cleaning portion 1022 on the side near the dust removal outlet 1032. The cleaning portion 1022 is located on the side of the teeth 1021 away from the energy release module 101.

[0030] See also Figure 2In some embodiments, the striker 102 includes a striker body 1024, which is roughly in the shape of a long strip. A plurality of teeth 1021 and a cleaning portion 1022 are arranged on the same side of the striker body 1024. The striker 102 can be made of a material with higher hardness, such as metal or alloy. Relevant technicians can design it according to the model and use environment of different equipment. This application does not specify the specific material and style of the striker. A plurality of teeth 1021 are provided on the side of the striker 102 close to the cleaning outlet 1032. The teeth 1021 are arranged on the striker 102 at equal distances in a direction parallel to the axis of the striker 102. The teeth 1021 can be in a herringbone or square shape, etc. This application does not limit the shape of the teeth 1021. The number of teeth 1021 is set by relevant technicians according to the actual application equipment size.

[0031] The cleaning portion 1022 is disposed on a side of the tooth portion 1021 away from the energy release module 101 and is aligned with the tooth portion 1021 . Thus, the tooth portion 1021 and the cleaning portion 1022 slide synchronously with the striker 102 in the striker channel 1031 .

[0032] The present invention provides a cleaning outlet 1032 in the striker channel 1031 of the striker device 100, and provides a plurality of teeth 1021 and a cleaning portion 1022 on the side of the striker 102 near the cleaning outlet 1032, with the cleaning portion 1022 being provided on the side of the teeth 1021 away from the energy release module 101. Thus, as the striker 102 slides within the striker channel 1031, it can drive the cleaning portion 1022 to clean debris in the striker channel 1031 and discharge it through the cleaning outlet 1032, thereby reducing the probability of the striker device 100 malfunctioning due to foreign matter. Furthermore, the striker 102 provided with the cleaning portion 1022 can increase the weight of the front portion of the striker 102, thereby increasing its stability and inertia when striking or pushing other mechanical components, thereby reducing the possibility of the striker 102 deflecting and improving the stability of the striker 102.

[0033] like Figure 1As shown, in some embodiments, the height H1 of the cleaning portion 1022 is less than the height H2 of the firing pin channel 1031, and the height difference between the height H1 of the cleaning portion 1022 and the height H2 of the firing pin channel 1031 is less than or equal to a predetermined value, such that the height H1 of the cleaning portion 1022 is slightly less than the height H2 of the firing pin channel 1031. In this manner, the cleaning portion 1022 can slide within the firing pin channel 1031, and the gap between the cleaning portion 1022 and the firing pin channel 1031 is small, thereby removing debris from the firing pin channel 1031 as much as possible, reducing the probability of hard objects or debris such as dust, sand, or steel nail fragments in the construction environment entering the gun body, and ensuring the safety and stability of the firing pin device 100 during operation. In one embodiment, when the cleaning channel 1031 is cylindrical, the cleaning portion 1022 is also cylindrical, and the diameter of the cleaning portion 1022 is smaller than the inner diameter of the firing pin channel 1031.

[0034] It can be understood that the cleaning portion 1022 slides synchronously with the firing pin 102, and the height H1 of the cleaning portion 1022 is slightly smaller than the height H2 of the firing pin channel 1031. On the one hand, it ensures that the moving trajectory of the firing pin 102 is fixed during each strike, further reducing the possibility of the firing pin 102 being deflected and improving the stability of the firing pin 102. On the other hand, it can reduce the gap between the cleaning portion 1022 and the inner wall of the firing pin channel 1031, thereby reducing the probability of debris getting stuck between the cleaning portion 1022 and the firing pin channel 1031.

[0035] Please refer again Figure 1 In some embodiments, the striker device 100 further includes a ratchet assembly 104, which is used to drive the striker 102 to slide within the striker channel 1031 in a direction approaching the energy release module 101. The ratchet assembly 104 includes a rotatable gear structure 1041. The gear structure 1041 of the ratchet assembly 104 engages with a plurality of teeth 1021 on the striker 102, converting the rotational motion of the gear into linear motion of the striker 102, thereby driving the striker 102 to slide through the gear rotation. In one embodiment, the ratchet assembly 104 is further provided with a plurality of tooth pins 1041a. Accordingly, tooth grooves 1023 are formed between the cleaning portion 1022 on the striker 102 and adjacent teeth 1021, and between two adjacent teeth 1021. The tooth pins 1041a and the tooth grooves 1023 engage with each other to drive the striker 102 to slide within the striker channel 1031.

[0036] Thus, in the striker device 100, when the tooth groove 1023 on the striker 102 is disengaged from the tooth pin 1041a, the energy release module 101 releases energy in the second state and slides in the striker channel 1031 in a direction away from the energy release module 101 to strike other mechanical parts, such as a nail. Figure 1After the nail is ejected, the ratchet assembly 104 drives the striker 102 away from the dust removal outlet 1032 through the meshing of the tooth groove 1023 on the striker 102 and the tooth pin 1041, thereby causing it to slide within the striker channel 1031 toward the energy release module 101. At this point, the energy release module 101 is in the first state and converts mechanical energy into air pressure or hydraulic energy within the cylinder 1012, providing energy for the next strike. The present invention does not limit the model of the energy release module 101; those skilled in the art may select one based on their specific circumstances.

[0037] Specifically, the working principle of the striker device 100 is described by taking the striker device 100 as an example. Figure 1 , nail gun 10 starts the motor ( Figure 1 (not shown), the ratchet assembly 104 is driven to rotate by the motor, and the tooth groove 1023 on the striker 102 is engaged with the tooth pin 1041a, thereby driving the striker 102 to slide from the initial locking position in the direction close to the energy release module 101, so that the pusher 1011 compresses the air to store energy in the cylinder 1012, that is, the energy release module 101 is in the first state. When the striker 102 slides to the first position, that is, the striker 102 is located in the striker channel 1031 at the farthest distance from the dust removal outlet 1032 (for example Figure 1 The cleaning portion 1022 completely closes the gap between the firing pin channel 1031 and the ratchet assembly 104, reducing the probability of debris entering the ratchet assembly 104 and causing malfunctions, reducing the impact on the operation of the ratchet assembly 104, and effectively protecting the nail gun 10, thereby improving the safety of the nail gun 10. Figure 3 When the tooth groove 1023 on the firing pin 102 disengages from the tooth pin 1041a, the energy release module 101 enters the second state and releases mechanical energy, pushing the firing pin 102 to slide within the firing pin channel 1031 in the direction of the energy release module 101 to the initial locked position, thereby driving the firing pin 102 to strike a nail (not shown) pushed into the nail seat by the nail pusher in the nail magazine, thereby ejecting the nail. At this time, regardless of the nailing posture, even the muzzle-up firing posture, the firing pin 102 is provided with a cleaning portion 1022. As the firing pin 102 slides within the firing pin channel 1031, it can drive the cleaning portion 1022 to clean debris from the firing pin channel 1031 and discharge it through the dust removal outlet 1032. The initial locked position is the position of the firing pin 102 when the nail gun 10 is not in use. This application does not limit the specific locked position.

[0038] In some embodiments, as Figure 3As shown, a blocking portion 1033 is formed on the inner wall of the firing pin channel 1031 at the ash cleaning outlet 1032 away from the energy release module 101. The blocking portion 1033 and the ash cleaning outlet 1032 are arranged on the same side of the firing pin channel 1031. Accordingly, a slot 1022a is formed at the connection between the firing pin body 1024 and the cleaning portion 1022 away from one end of the energy release module 101. When the slot 1022a and the blocking portion 1033 are engaged, the cleaning portion 1032 can be blocked from sliding. The blocking portion 1033 can be a protrusion connected to the gun nozzle, or it can be a baffle structure on the housing of the equipment containing the firing pin device 100. The present application does not limit the specific style of the blocking portion 1033.

[0039] When the striker 102 slides until the cleaning portion 1022 abuts against the blocking portion 1033, the cleaning portion 1022 covers the dust removal outlet 1032, thereby further reducing the probability of dust or debris entering the striker channel 1031 through the dust removal outlet 1032. The dust removal outlet 1032 can be square or other shapes. The present invention does not limit the shape and size of the dust removal outlet 1032, and relevant technicians can configure it according to actual conditions.

[0040] Please refer again Figure 1 and Figure 2 In some embodiments, the height H3 of the tooth portion 1021 is less than or equal to the height H2 of the cleaning portion 1022. This can reduce the volume of the tooth portion 1021, thereby reducing the weight of the striker device 100 while ensuring the sliding efficiency of the striker 102 within the striker channel 1031.

[0041] In some embodiments, the cross-sectional shape of the cleaning portion 1022 is consistent with the cross-sectional shape of the firing pin channel 1031, wherein the cross-sectional shape of the cleaning portion 1022 and the cross-sectional shape of the firing pin channel 1031 are planes obtained along a section line perpendicular to the firing pin channel 1031 and perpendicular to the sliding direction of the firing pin 102. In this way, the cleaning portion completely blocks the cross-sectional shape of the firing pin channel 1031, which can effectively reduce the probability of debris entering the firing pin channel 1031 from the gap between the cleaning portion 1022 and the firing pin channel 1031, reduce the probability of debris getting stuck in the ratchet assembly 104 or other dangerous operations, and ensure the safety and stability of the firing pin device 100 during operation. The cross-sectional shape of the firing pin channel 1031 can be other shapes such as circular, square, or hexagonal. The present invention does not limit the cross-sectional shape and size of the firing pin channel 1031. Relevant technicians can adjust it according to different application environments and equipment, and the cleaning portion 1022 is adjusted accordingly.

[0042] Accordingly, the embodiment of the present invention further provides a nail gun 10, Figure 4 is a schematic diagram of a nail gun 10, as shown Figure 4As shown, the nail gun 10 includes the firing pin device 100 described in any of the above embodiments. For the parts that are the same or corresponding to the previous embodiment, please refer to the corresponding description of the above embodiment and will not be described in detail below.

[0043] It should be noted that, for the sake of simplicity of description, the aforementioned method embodiments are all expressed as a series of action combinations. However, those skilled in the art should know that the present invention is not limited to the described order of actions, because according to the present invention, certain steps can be performed in other orders or simultaneously.
