[0002] In practical applications, the anti-mechanical impact performance of a glass-ceramic panel needs to meet corresponding requirements. In the application of induction cooker products, the anti-mechanical impact performance of the glass-ceramic panel is particularly important.

[0003] In the detection of the anti-mechanical impact performance of the glass-ceramic panel for induction cooker products, the detection results of existing methods often do not match the actual use situation, which is not conducive to the accurate matching between the glass-ceramic panel and the induction cooker product, and causes a certain obstacle to the accurate and full application of the glass-ceramic material.

[0004] In view of this, the present application is specifically proposed. Summary of the Invention

Under the condition of ensuring the quality requirements of the glass-ceramic panel, it can more accurately screen the glass-ceramic panel suitable for the induction cooker product.

[0022] The inner wall of the annular inner cavity is also provided with a reflux hole, which is communicated with the medium cavity through a reflux channel.

[0023] The system for testing the anti-mechanical impact performance of the glass-ceramic panel further includes: a reflux push rod. The reflux push rod is used to push the second piston through the extension hole and the control cylinder, so as to send the liquid medium in the storage cavity into the annular inner cavity.

[0024] The liquid medium is a heat-conducting medium.

[0025] Furthermore, along the axial direction of the reflux push rod, the reflux push rod is slidably matched with the control cylinder. Along the circumferential direction of the reflux push rod, the reflux push rod is fixedly matched with the control cylinder.

[0026] Furthermore, the reflux channel includes: a reflux pipe. The reflux pipe is located outside the base body. One end of the reflux pipe is communicated with the reflux hole, and the other end is communicated with the medium cavity. The reflux pipe is made of heat-conducting material.

[0027] Furthermore, a balance hole is opened on the side wall of the impact cavity near the medium cavity end, and the balance hole penetrates through to the surface of the base body.

The top end of the sealing plate is in contact with the first stop bar, and the bottom end of the sealing plate is in contact with the second stop bar.

[0032] The reference plate is arranged perpendicular to the axial direction of the ventilation cylinder and is located on the side of the second stop bar away from the first stop bar. The reference plate is connected to the top wall / bottom wall of the ventilation cylinder by elastic glue dots. The reference plate is connected to the sealing plate by a connecting column.

[0038] Even if the driving mechanism accidentally controls the impact head to strike the glass-ceramic panel to be tested with a force greater than the preset force, during the impact process, when the connecting piece switches to the second sliding position, the impact force can be reduced through the "force receiving" process, avoiding direct damage to the glass-ceramic panel to be tested due to excessive impact force, improving the protection effect of the glass-ceramic panel to be tested during the detection process, and avoiding accidental damage to the detection object.

[0039] Generally speaking, the glass-ceramic panel anti-mechanical impact performance testing system provided by the embodiment of the present invention can more accurately simulate the mechanical impact situation of the glass-ceramic panel of the induction cooker product during the actual use process, facilitating a more practical detection of the specific application effect of the glass-ceramic panel in the induction cooker product, so as to more accurately judge whether the glass-ceramic panel meets the application standards in the induction cooker product. Under the condition of ensuring the quality requirements of the glass-ceramic panel, it can more accurately screen the glass-ceramic panel suitable for the induction cooker product. This can effectively improve the detection accuracy of the glass-ceramic panel to be tested, so as to more accurately evaluate the actual use performance of the glass-ceramic panel to be tested, and thus accurately match the use of the glass-ceramic panel to be tested, avoiding unnecessary waste of the glass-ceramic panel to be tested.

Detailed implementation manners

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0053] Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0054] It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not require further definition and explanation in subsequent drawings.

[0055] The terms "first", "second", etc. are only used for descriptive distinction and should not be construed as indicating or implying relative importance.

[0056] In addition, terms such as "parallel" and "perpendicular" do not mean that the components are required to be absolutely parallel or perpendicular, but may be slightly inclined. For example, "parallel" only means that its direction is relatively more parallel than "perpendicular", and does not mean that the structure must be completely parallel, but may be slightly inclined.

[0057] In the description of the present invention, it should also be noted that unless otherwise clearly defined and limited, the terms "arranged", "installed", and "connected" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium, and may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention may be understood according to specific circumstances.

[0058] The inventors of the present application have found through research that in the detection of the anti-mechanical impact performance of traditional microcrystalline glass panels, usually an impact device is used to directly impact the microcrystalline glass panel a preset number of times to determine whether the anti-mechanical impact performance of the microcrystalline glass panel meets the requirements. However, when the microcrystalline glass panel is applied to an induction cooker, this detection method has a large difference from the actual use situation of the induction cooker, and its detection result is easily different from the actual use situation, which directly leads to a reduction in the reference value of the detection result.

[0059] Among them, the mechanical shocks faced by induction cookers are not simply impact methods in many cases. During the use of an induction cooker, it is used for cooking. Exemplarily, when a user is stir-frying, if the user accidentally uses too much force to stir-fry, it will cause the spatula to hit the wok with a relatively large initial force, and the mechanical shock is transmitted to the ceramic glass panel through the pot body. Particularly, when the spatula hits the pot body, the user can receive the tactile feedback of the impact force. When the user realizes that the force is too large (especially for users with relatively rich cooking experience), the user will subconsciously reduce the force. That is to say, during the stir-frying process, even if the ceramic glass panel is subjected to an impact with a relatively strong initial intensity, after being stressed, the impact intensity weakens from strong to weak during the entire impact process.

[0060] In addition, during the stir-frying process, after the spatula hits the pot body, it will not directly separate from the pot body but will perform a stir-frying action along the pot body. That is, after the spatula hits the pot body, it will still move along the pot body for a certain distance with a certain force.

[0061] These are all the differences between the use process of the induction cooker and the traditional mechanical shock test, which will cause the traditional test method to be unable to accurately reflect the actual use situation, resulting in a reduced reference value of the test results.

[0062] During the actual production process, in order to ensure that the ceramic glass panel can meet the usage requirements of the induction cooker, when using the traditional method for mechanical shock detection, it is usually detected with higher standards. Although this can ensure that the qualified ceramic glass panel can meet the usage requirements of the induction cooker, the improvement of the standard will lead to an incorrect increase in the unqualified rate of the ceramic glass panel, and there will be a situation where the ceramic glass panel that actually meets the usage requirements of the induction cooker is judged as unqualified, resulting in waste of the ceramic glass panel.

[0063] To overcome the above defects, please refer to Figures 1-4 , this embodiment provides a test system for the anti-mechanical shock performance of a ceramic glass panel.

[0064] The test system for the anti-mechanical shock performance of the ceramic glass panel includes: a base body 100, an impact head 200, a connecting member 300, an elastic member 400, and a first piston 500.

[0065] The base body 100 is provided with a medium cavity 110, an impact cavity 120, and a storage cavity 130.

[0066] The impact cavity 120 communicates with the medium cavity 110. In this embodiment, the impact cavity 120 and the medium cavity 110 are coaxially arranged. The impact cavity 120 penetrates to the surface of the base body 100. Both the medium cavity 110 and the impact cavity 120 are spaced from the storage cavity 130.

[0067] The first piston 500 is slidably fitted in the medium chamber 110 and is slidably sealed with the inner wall of the medium chamber 110. The connecting member 300 is slidably fitted in the impact chamber 120 and is slidably sealed with the inner wall of the impact chamber 120.

[0068] The side wall of the impact chamber 120 is provided with a first flow channel 121 and a second flow channel 122. The first flow channel 121 communicates with the medium chamber 110, and the second flow channel 122 communicates with the storage chamber 130.

[0069] The connecting member 300 is provided with a connecting flow channel 310. The connecting member 300 has a first sliding position and a second sliding position.

[0070] When the connecting member 300 is located at the first sliding position, both the first flow channel 121 and the second flow channel 122 are offset from the connecting flow channel 310, and the connection between the first flow channel 121 and the second flow channel 122 is blocked by the connecting member 300.

[0071] When the connecting member 300 is located at the second sliding position, both the first flow channel 121 and the second flow channel 122 communicate with the connecting flow channel 310, and the first flow channel 121 and the second flow channel 122 are communicated through the connecting member 300.

[0072] The medium chamber 110 is used to accommodate a liquid medium.

[0073] The elastic member 400 abuts between the first piston 500 and the connecting member 300, and the impact chamber 120 is provided with an anti - detachment mechanism 123 for preventing the connecting member 300 from disengaging.

[0074] In the initial state, the connecting member 300 is located at the first sliding position, and the connecting flow channel 310 is located on the side of the first flow channel 121 and the second flow channel 122 away from the medium chamber 110. The impact head 200 is installed at one end of the connecting member 300 away from the medium chamber 110. Under the elastic force of the elastic member 400, the impact head 200 fully extends out of the base body 100.

[0075] During detection, a driving mechanism can be used to drive the base body 100 so that the impact head 200 can mechanically impact the surface of the microcrystalline glass panel to be measured. After the impact head 200 contacts the surface of the microcrystalline glass panel to be measured, as the base body 100 further approaches the microcrystalline glass panel to be measured, the impact head 200 will be pushed into the impact chamber 120 by the microcrystalline glass panel to be measured. Since the medium chamber 110 contains a liquid medium, the first piston 500 will not move, and the elastic member 400 is elastically compressed. During this process, the impact force gradually increases, and the connecting member 300 is pushed from the first sliding position to the second sliding position.

[0076] As the substrate 100 continues to approach the microcrystalline glass panel to be tested, when the connecting member 300 is pushed to the second sliding position, the first flow channel 121 and the second flow channel 122 are communicated through the connecting flow channel 310 of the connecting member 300. As Figure 5 shown, at this time, the liquid medium in the medium cavity 110 can enter the storage cavity 130 through the first flow channel 121, the connecting flow channel 310 and the second flow channel 122. In this way, the first piston 500 can move along the medium cavity 110 towards the end away from the impact cavity 120, so that the first piston 500 can "recede" relative to the microcrystalline glass panel to be tested. During this process, the impact force on the microcrystalline glass panel to be tested can be reduced to a certain extent, realizing the simulation of "force receiving", as Figure 6 shown.

[0077] When the liquid medium cannot enter the storage cavity 130 further (for example, the storage cavity 130 has been filled), the first piston 500 can no longer continue to "recede". At this time, the substrate 100 can be driven to translate relative to the surface of the microcrystalline glass panel to be tested according to the force after this "force receiving", so as to realize the simulation of the stir-frying action.

[0078] Through the above design, the microcrystalline glass panel anti-mechanical impact performance test system can more accurately restore the impact situation of the microcrystalline glass panel to be tested during the use of the induction cooker, so as to ensure the credibility of the detection results.

[0079] On this basis, when using the driving mechanism to drive the substrate 100 to make the impact head 200 impact the microcrystalline glass panel to be tested, even if the driving mechanism accidentally controls the impact head 200 to impact the microcrystalline glass panel to be tested with a force greater than the preset force, during the impact process, when the connecting member 300 switches to the second sliding position, the impact force can be reduced through the "force receiving" process, avoiding direct damage to the microcrystalline glass panel to be tested due to excessive impact force, improving the protection effect of the detection process on the microcrystalline glass panel to be tested, and avoiding accidental damage to the detection object.

[0080] Generally speaking, the microcrystalline glass panel anti-mechanical impact performance test system provided in this embodiment can more accurately simulate the mechanical impact situation of the microcrystalline glass panel of the induction cooker product during the actual use process, facilitating a more practical detection of the specific application effect of the microcrystalline glass panel in the induction cooker product, so as to more accurately judge whether the microcrystalline glass panel meets the application standards in the induction cooker product. On the premise of ensuring the quality requirements of the microcrystalline glass panel, it can more accurately screen the microcrystalline glass panel suitable for the induction cooker product. This can effectively improve the detection accuracy of the microcrystalline glass panel to be tested, so as to more accurately evaluate the actual use performance of the microcrystalline glass panel to be tested, and thus accurately match the use of the microcrystalline glass panel to be tested, avoiding unnecessary waste of the microcrystalline glass panel to be tested.

[0081] It can be understood that the mechanical shock resistance performance test system for the glass-ceramic panel can also set up an installation platform according to actual needs. The installation platform is used to install the glass-ceramic panel to be tested. The driving mechanism can adopt a robotic arm, and is not limited thereto. For the convenience of detection, other components can also be set up according to actual needs, which will not be elaborated here.

[0082] In this embodiment, the cross-sections of the dielectric cavity 110, the impact cavity 120, and the storage cavity 130 are all circular. The connecting member 300 is cylindrical, and the outer side wall of the connecting member 300 fits against the inner wall of the impact cavity 120.

[0083] The elastic member 400 can be selected as a spring, and is not limited thereto.

[0084] The impact cavity 120 is provided with a balance hole 125 communicating with the external atmosphere to balance the air pressure at the elastic member 400 in the impact cavity 120 during the impact process.

[0085] Furthermore, one end of the connecting member 300 close to the dielectric cavity 110 is further provided with an adjusting cylinder 320, an adjusting rod 330, and a rotating member 340.

[0086] The rotating member 340 is located on the side of the adjusting cylinder 320 close to the dielectric cavity 110. The adjusting cylinder 320 has internal threads, the adjusting rod 330 has external threads, and the adjusting rod 330 and the adjusting cylinder 320 are in threaded cooperation. The rotating member 340 is fixedly connected to the adjusting rod 330.

[0087] The elastic member 400 abuts between the first piston 500 and the rotating member 340. The adjusting cylinder 320 fits against one end of the connecting member 300 close to the dielectric cavity 110.

[0088] Through this design, the distance between the rotating member 340 and the first piston 500 in the initial state can be adjusted by rotating the rotating member 340, so as to change the elastic force of the elastic member 400 in the initial state, and thus the impact force of the impact head 200 when impacting the glass-ceramic panel to be tested can be regulated.

[0089] Optionally, a contact member 350 can also be provided on the side of the rotating member 340 close to the elastic member 400; along the axial direction of the impact cavity 120, the contact member 350 is in sliding fit with the impact cavity 120; along the circumferential direction of the impact cavity 120, the contact member 350 is in fixed fit with the impact cavity 120. The rotating member 340 is in rotational fit with the contact member 350, and a driver can be built in the contact member 350 to drive the rotating member 340 to adjust the impact force. The elastic member 400 abuts between the contact member 350 and the first piston 500.

[0090] In this embodiment, a stopper 111 for preventing the first piston 500 from leaving the medium chamber 110 is provided at one end of the medium chamber 110 close to the impact chamber 120. In the initial state, the first piston 500 abuts against the stopper 111. The liquid medium is located on the side of the first piston 500 away from the impact chamber 120.

[0091] A relief groove 124 is also formed on the inner side wall of one end of the impact chamber 120 close to the medium chamber 110. The relief groove 124 extends continuously in a circumferential direction of the impact chamber 120 to form a ring shape, and the relief groove 124 extends in an axial direction of the impact chamber 120. The anti - detachment mechanism 123 is an anti - detachment ring. The anti - detachment mechanism 123 is disposed around one end of the adjusting cylinder 320 close to the rotating member 340. The outer diameter of the anti - detachment mechanism 123 is adapted to the relief groove 124, and the anti - detachment mechanism 123 is slidably engaged with the relief groove 124. Wherein, the adjusting cylinder 320 is fixedly connected to the connecting member 300. During the detection process, the connecting member 300 will never completely enter the relief groove 124.

[0092] The impact head 200 is detachably connected to the connecting head, so as to facilitate the replacement of the required type of impact head 200 as needed.

[0093] Furthermore, a second piston 131 and a control cylinder 132 are also provided in the storage chamber 130.

[0094] The second piston 131 is slidably engaged in the storage chamber 130 and is slidably sealed with the inner wall of the storage chamber 130.

[0095] The second flow channel 122 is located at one end face of the storage chamber 130. An extension hole 133 is formed at one end of the storage chamber 130 away from the second flow channel 122, and the extension hole 133 penetrates through to the surface of the base body 100. The control cylinder 132 is located on the side of the second piston 131 away from the second flow channel 122. The extension hole 133 has an internal thread, and the control cylinder 132 has an external thread. The control cylinder 132 is threadedly engaged with the extension hole 133 and extends into the storage chamber 130.

[0096] With this design, by rotating the control cylinder 132, the length of the control cylinder 132 extending into the storage chamber 130 can be changed, so as to adjust the space in which the second piston 131 can slide along the storage chamber 130. In this way, when the liquid medium enters the storage chamber 130, the second piston 131 can move at most until it abuts against the control cylinder 132. After the second piston 131 abuts against the control cylinder 132, the liquid medium can no longer continue to enter the storage chamber 130 from the medium chamber 110, thus reaching the "force - receiving" end point.

[0097] Furthermore, the base body 100 is also provided with an annular inner cavity 140. The annular inner cavity 140 is disposed around the impact chamber 120 and is spaced apart from the impact chamber 120. Specifically, the annular inner cavity 140 is disposed outside the receiving groove, and the annular inner cavity 140 corresponds to the elastic member 400.

[0098] A communication gap that communicates with the relief groove 124 of the annular inner cavity 140 is provided on the inner wall of the impact cavity 120. The communication gap extends along the length direction of the annular inner cavity 140. An isolation member 141 is accommodated in the communication gap. The isolation member 141 seals the communication gap. The isolation member 141 is made of a heat-conducting material.

[0099] One end face of the storage cavity 130 where the second flow channel 122 is provided is further provided with a third flow channel 134. The third flow channel 134 communicates with one end of the annular inner cavity 140 close to the impact head 200. And a one-way mechanism 135 for preventing the liquid medium from flowing back into the storage cavity 130 is provided in the third flow channel 134. The one-way mechanism 135 can be selected as a one-way valve, and is not limited thereto.

[0100] A return hole 142 is further provided on the inner wall of the annular inner cavity 140. The return hole 142 is located at one end of the annular inner cavity 140 far from the impact head 200. The return hole 142 communicates with the medium cavity 110 through a return channel 143. Both the first flow channel 121 and the return channel 143 communicate with one end of the medium cavity 110 far from the impact cavity 120.

[0101] The microcrystalline glass panel anti-mechanical impact performance test system further includes: a return push rod 600. The outer diameter of the return push rod 600 is smaller than the inner diameter of the control cylinder 132.

[0102] The return push rod 600 is used to push the second piston 131 through the extension hole 133 and the control cylinder 132, so as to send the liquid medium in the storage cavity 130 into the annular inner cavity 140.

[0103] Wherein, the liquid medium is a heat-conducting medium.

[0104] After one impact is completed, the driving mechanism drives the base body 100 away from the microcrystalline glass panel to be tested, and the impact head 200 is separated from the microcrystalline glass panel to be tested. Under the action of the elastic member 400, the impact head 200 extends out of the base body 100 again. The anti-disengagement mechanism 123 abuts against one end of the relief groove 124 close to the impact head 200. At this time, the connecting member 300 is at the first sliding position, and the first flow channel 121 and the second flow channel 122 are not communicated. The return push rod 600 can be used to push the second piston 131 to make the second piston 131 return to one end of the storage cavity 130 far from the extension hole 133 to achieve reset. At the same time, the liquid medium in the storage cavity 130 is pushed into the annular inner cavity 140 through the third flow channel 134, and the excess liquid medium returns to the medium cavity 110 through the return hole 142 and the return channel 143, realizing the recycling of the liquid medium.

[0105] With this design, during repeated impacts, the liquid medium continuously enters the storage cavity 130 from the medium cavity 110, and then returns to the medium cavity 110 from the storage cavity 130 through the annular inner cavity 140, realizing the internal circulation of the liquid medium. During this process, the liquid medium in the annular inner cavity 140 can absorb the heat in the relief groove 124 through the isolation member 141, achieving the cooling of the elastic member 400, so that the elastic member 400 always remains within a suitable temperature range, ensuring the stability of the elastic coefficient of the elastic member 400 and facilitating the precise control of the impact force.

[0106] Optionally, along the axial direction of the return push rod 600, the return push rod 600 is slidably engaged with the control cylinder 132. Along the circumferential direction of the return push rod 600, the return push rod 600 is fixedly engaged with the control cylinder 132. By driving the return push rod 600 to rotate, the position of the control cylinder 132 can be adjusted, thereby regulating the amount of liquid medium that can be accommodated in the storage cavity 130, achieving the purpose of changing the "force-receiving" amplitude.

[0107] Furthermore, the return channel 143 includes: a return pipe. The return pipe is located outside the base body 100. One end of the return pipe is communicated with the return hole 142, and the other end is communicated with the medium cavity 110. The return pipe is made of a heat-conducting material. In this way, during the process of the driving mechanism driving the base body 100 to move, there will be air flow around the return channel 143, realizing the cooling of the liquid medium in the return channel 143, thereby ensuring the cooling effect of the liquid medium on the elastic member 400.

[0108] Furthermore, the balance hole 125 is opened on the side wall of the impact cavity 120 near the medium cavity 110, and the balance hole 125 penetrates through to the surface of the base body 100.

[0109] The impact cavity 120 is located at the bottom of the base body 100, that is, the impact cavity 120 is arranged downward. A liquid heat-conducting medium is accommodated on the side of the connecting member 300 close to the medium cavity 110. Specifically, the abutting member 350 is slidably engaged in the relief groove 124 and is slidably sealed with the inner wall of the relief groove 124. The liquid heat-conducting medium is located on the side of the abutting member 350 away from the rotating member 340. During the impact process, the liquid level of the liquid heat-conducting medium is always below the balance hole 125, that is to say, when the abutting member 350 moves upward to the closest position to the first piston 500, after the liquid level of the liquid heat-conducting medium stabilizes, the liquid level of the liquid heat-conducting medium is still below the balance hole 125.

[0110] With this design, during the impact process, the abutting member 350 can push up / lift the liquid heat-conducting medium, so that the liquid heat-conducting medium can better absorb the heat at the end of the elastic member 400 close to the first piston 500, in order to improve the cooling effect on the elastic member 400. The heat absorbed by the liquid heat-conducting medium is transferred by the isolation member 141 to the liquid medium in the annular inner cavity 140 to achieve heat dissipation.

[0111] To prevent the liquid heat-conducting medium from being accidentally ejected from the balance hole 125 when the abutting member 350 pushes up / lifts the liquid heat-conducting medium, a ventilation mechanism 700 is disposed in the balance hole 125, as Figure 7 shown.

[0112] The ventilation mechanism 700 includes: a ventilation cylinder 710, a first stop bar 720, a second stop bar 730, a sealing plate 740, a connecting column 750, and a reference plate 760.

[0113] The cross-section of the internal space of the ventilation cylinder 710 is rectangular.

[0114] The first stop bar 720 is disposed on the top wall of the ventilation cylinder 710 and extends along the width direction of the ventilation cylinder 710. The second stop bar 730 is disposed on the bottom wall of the ventilation cylinder 710 and extends along the width direction of the ventilation cylinder 710. The lengths of both the first stop bar 720 and the second stop bar 730 are the same as the width of the ventilation cylinder 710. Along the axial direction of the ventilation cylinder 710, the second stop bar 730 is located on the side of the first stop bar 720 away from the impact chamber 120.

[0115] The width of the sealing plate 740 is the same as the width of the ventilation cylinder 710. The sealing plate 740 is disposed between the first stop bar 720 and the second stop bar 730. The top end of the sealing plate 740 is in contact with the first stop bar 720 (the side of the top end of the sealing plate 740 away from the second stop bar 730 is in contact with the side of the first stop bar 720 close to the second stop bar 730). The bottom end of the sealing plate 740 is in contact with the second stop bar 730 (the side of the bottom end of the sealing plate 740 away from the first stop bar 720 is in contact with the side of the second stop bar 730 close to the first stop bar 720).

[0116] The reference plate 760 is disposed perpendicular to the axial direction of the ventilation cylinder 710 and is located on the side of the second stop bar 730 away from the first stop bar 720. The reference plate 760 is connected to the top wall / bottom wall of the ventilation cylinder 710 by elastic glue dots 770. The reference plate 760 is connected to the sealing plate 740 by the connecting column 750. The connecting column 750 is made of an elastic material. In the natural state, the reference plate 760 is disposed perpendicular to the axis of the ventilation cylinder 710. Since the reference plate 760 is connected to the ventilation cylinder 710 by the elastic glue dots 770, the reference plate 760 can deflect relative to the ventilation cylinder 710.

[0117] When the abutting member 350 moves towards the first piston 500, the air in the impact chamber 120 is discharged through the ventilation mechanism 700. During this process, the air pushes open the sealing plate 740. The bottom end of the sealing plate 740 is blocked by the second stop bar 730, and the top end of the sealing plate 740 is separated from the first seal and opened. Under the action of the connecting column 750, the reference plate 760 deflects towards the side away from the second stop bar 730. As Figure 8As shown in this way, it is possible to effectively prevent the upward-moving liquid heat-conducting medium from flowing out of the ventilation cylinder 710.

[0118] When the abutting member 350 moves towards the side where the impact head 200 is located, external air enters the impact chamber 120 through the ventilation mechanism 700. During this process, the air pushes open the sealing plate 740. The top end of the sealing plate 740 is blocked by the first stop bar 720, and the bottom end of the sealing plate 740 is separated from the second seal to be opened. Under the action of the connecting column 750, the reference plate 760 deflects towards the side close to the second stop bar 730. As Figure 9 shown in this way, it is possible to effectively prevent the liquid heat-conducting medium dripping from top to bottom from flowing out of the ventilation cylinder 710.

[0119] This can effectively reduce the loss of the liquid heat-conducting medium.

[0120] Optionally, the connecting flow channel 310 extends along the axial direction of the impact chamber 120.
