Detailed Implementation

[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] This utility model discloses a variable aperture mushroom cake punching device. This utility model designs a core shaft 03 and a punching tube 04 that are slidably and tightly fitted together in the grip tube 01. This punching device can punch holes of various apertures on the mushroom cake.

[0031] By designing a partition 02, a connecting rod 05, a guide rod 06, a pressing block 07, and a spring 08, different pressing blocks 07 are connected to punching tubes 04 with different punching diameters. When the operator pushes the pressing block 07, the corresponding punching tube 04 can extend out of the grip tube 01, which facilitates subsequent punching operations. Due to the elastic force of the spring 08, the punching tube 04 that has extended out of the grip tube 01 can be reliably reset.

[0032] By designing the sealing tube 10, on the one hand, it ensures that the perforated tube 04 will not easily come into contact with the outside world when the perforation device is not in use, thus preventing the perforated end of the perforated tube 04 from being contaminated with bacterial strains; on the other hand, combined with the design of the vent 101 and the disinfection components, when the perforated tube 04 needs to be disinfected, the sealing tube 10 is screwed onto the external threaded tube 010, and then the air pump 13 and the heating wire 12 are energized in sequence. The heating wire 12 can heat the gas blown out from the air pump 13. The high-temperature gas can stay in the sealing tube 10 for a period of time before being discharged from the vent 101. The high-temperature gas in the sealing tube 10 can thoroughly disinfect the perforated tube 04 at high temperature; at the same time, after the heating wire 12 is de-energized, the air pump 13 can quickly cool down the disinfected perforated tube 04, thereby shortening the disinfection time.

[0033] By designing the central rod 14, the stop block 15, and the pressing sleeve 16, when a punched tube 04 extends out of the grip tube 01 and completes the punching operation, the operator can press down the pressing sleeve 16 to simultaneously push the mandrel 03 and the remaining punched tubes 04 out of the grip tube 01, thereby smoothly and thoroughly pushing out the fungal block inside the punched tube 04 that has completed the punching.

[0034] By designing a limiting ring 012, a limiting ring 070, a positioning ring 17, a rod body 170, and a rod body 171, when a perforated tube 04 extends out of the grip tube 01, rotating the positioning ring 17 can position the pressing block 07 connected to the perforated tube 04, preventing it from automatically resetting.

[0035] Example

[0036] See appendix Figures 1-8 This is a schematic diagram of the overall and partial structure of one embodiment of the present invention. Specifically, the present invention discloses a variable-aperture mushroom cake punching device for punching holes in mushroom cakes. The punching device includes:

[0037] The grip tube 01 has a circular partition 02 integrally formed on its inner side, and the surface of the partition 02 is perpendicular to the center line of the grip tube 01.

[0038] The drilling assembly includes a spindle 03, a drilling tube 04, a connecting rod 05, a guide rod 06, a pressing block 07, and a spring 08; wherein multiple drilling tubes 04, connecting rods 05, guide rods 06, pressing blocks 07, and springs 08 are provided.

[0039] The mandrel 03 and the perforated tube 04 are coaxially arranged inside the grip tube 01. Multiple perforated tubes 04 are slidably and tightly fitted on the outside of the mandrel 03. The length and wall thickness of the multiple perforated tubes 04 are the same. The outer contour of the cross section of the mandrel 03 is circular. The perforated tube 04 is a circular tube. The outer wall of the mandrel 03 is in slidable and tightly contacted with the inner wall of the innermost perforated tube 04. The inner wall of one perforated tube 04 is in slidable and tightly contacted with the outer wall of another perforated tube 04 that is adjacent to it and located inside it.

[0040] One end wall of the mandrel 03 and one end wall of the multiple perforated tubes 04 can be aligned simultaneously. The other end wall of the mandrel 03 and the other end wall of the multiple perforated tubes 04 are each fixed to one end of the multiple connecting rods 05. The other end of the multiple connecting rods 05 is each fixed to one end of the multiple guide rods 06. The other end of the multiple guide rods 06 is each fixed to the multiple pressing blocks 07. The end of the pressing block 07 away from the guide rods 06 is located outside the grip tube 01.

[0041] The partition 02 has multiple circular through holes 020, and a guide rod 06 slides tightly through each through hole 020. Multiple springs 08 are each fitted onto multiple guide rods 06, and the two ends of the springs 08 are respectively pressed against the pressing block 07 and the partition 02. The end wall of the spindle 03 away from the connecting rod 05 and the end wall of the perforated tube 04 away from the connecting rod 05 can both be located outside the grip tube 01.

[0042] When it is necessary to use a perforated tube 04 to punch holes in the mushroom cake, push the pressing block 07 connected to the perforated tube 04 along the length of the grip tube 01. The spring 08 corresponding to the perforated tube 04 is compressed. The end of the perforated tube 04 away from the connecting rod 05 will extend out of the grip tube 01, while the rest of the perforated tube 04 remains stationary. The part of the perforated tube 04 that extends out of the grip tube 01 can punch holes in the mushroom cake. When punching, a circular mushroom block will be embedded inside the perforated tube 04.

[0043] After the perforated tube 04 extending from the gripping tube 01 completes the perforation of the mycelium cake, there are two ways to remove the circular mycelium block embedded inside the perforated tube 04:

[0044] The first method is to directly release the previously pushed pressing block 07. Due to the elastic force of the spring 08, the punching tube 04 that performs the punching operation will reset. Since the mandrel 03 or other punching tubes 04 are arranged inside the punching tube 04, when the previously extended punching tube 04 resets, the mandrel 03 or other punching tubes 04 located inside the extended punching tube 04 will push the fungal block out.

[0045] The second method is to keep the position of the perforated tube 04 unchanged, while pushing the other multiple pressing blocks 07, thereby causing the spindle 03 and the other multiple perforated tubes 04 to move. That is, the spindle 03 and the other multiple perforated tubes 04 also extend out of the grip tube 01. When the spindle 03 and the other multiple perforated tubes 04 extend out, they will push out the fungal block inside the perforated tube 04.

[0046] More specifically, it also includes a sealing tube 10 with a circular cross-sectional outline, one end of which is closed, and the inner side of the sealing tube 10 is provided with internal threads; the end of the grip tube 01 away from the pressing block 07 is coaxially and integrally formed with an externally threaded tube 010, and the outermost wall of the multiple perforated tubes 04 slides and fits tightly against the inner wall of the externally threaded tube 010; the end of the mandrel 03 away from the pressing block 07 and the ends of the multiple perforated tubes 04 away from the pressing block 07 can be simultaneously aligned with the end of the externally threaded tube 010 away from the grip tube 01; the sealing tube 10 can be threadedly screwed into the externally threaded tube 010; one of the functions of the sealing tube 10 is to shield the mandrel 03 and the multiple perforated tubes 04 to prevent them from being contaminated.

[0047] More specifically, it also includes a disinfection component, which includes a support 11, a heating wire 12, and an air pump 13. The cross-shaped support 11 is fixed inside the sealing tube 10, the spiral heating wire 12 is fixed on the support 11, and the air pump 13 is fixed on the sealing tube 10. A vent hole 100 is provided in the center of the closed end of the sealing tube 10, and the air outlet end of the air pump 13 is connected to the vent hole 100. A plurality of vent holes 101 are provided on the outer side wall of the sealing tube 10. The plurality of vent holes 101 are evenly arranged along the circumference of the sealing tube 10. The heating wire 12 is located between the vent hole 100 and the vent hole 101. The vent hole 101 can be located between the heating wire 12 and the end of the external threaded tube 010 away from the grip tube 01.

[0048] After completing the perforation of the mushroom cake or when it is necessary to change the perforation diameter, the perforation tube 04 needs to be disinfected to avoid colony contamination. When disinfecting the perforation tube 04, first ensure that all perforation tubes 04 are in their initial state, i.e., the end wall of the mandrel 03 away from the connecting rod 05 is aligned with the end walls of the perforation tubes 04 away from the connecting rod 05. Then, the sealing tube 10 can be installed. After the sealing tube 10 is installed, the air pump 13 and the heating wire 12 are energized sequentially. The air outlet of the air pump 13 blows air towards the end of the perforation tube 04, and the heating wire 12 is located at the air outlet of the air pump 13. Between the end and the perforated tube 04, the gas blown by the air pump 13 is heated when it passes through the heating wire 12. The high-temperature airflow after heating will disinfect the end of the perforated tube 04 at high temperature. By designing the vent hole 101, on the one hand, the air pump 13 blows air into the inside of the sealing tube 10, and the vent hole 101 can exhaust the air to ensure the air pressure balance inside the sealing tube 10. On the other hand, after the heating wire 12 is powered on for a period of time and then powered off, the air pump 13 continues to be powered on for a period of time, that is, the air pump 13 continues to blow air, which can achieve rapid cooling of the heating wire 12 and the perforated tube 04, improve the disinfection efficiency, and at the same time avoid scalding the user.

[0049] The grip tube 01, the perforated tube 04, and the sealing tube 10 are all made of metal and will not be melted by high-temperature gas during the high-temperature sterilization process.

[0050] Multiple elongated holes 011 are provided on the side wall of the grip tube 01. The length direction of the elongated holes 011 is parallel to the center line of the grip tube 01. The multiple elongated holes 011 are evenly arranged along the circumference of the grip tube 01. A pressing block 07 is slidably arranged in each elongated hole 011. The pressing block 07 can abut against the two wide inner side walls of the elongated hole 011. The elongated holes 011 can limit the pressing block 07 to prevent the pressing block 07 from moving too far and to prevent the pressing block 07 from moving arbitrarily along the circumference of the grip tube 01.

[0051] More specifically, it also includes a center rod 14, a stop block 15, and a pressing sleeve 16. The center rod 14, with a circular cross-sectional outline, is coaxially arranged with the grip tube 01. One end of the center rod 14 is fixed to the partition plate 02, and the other end of the center rod 14 is coaxially fixed with a stop block 15, which also has a circular cross-sectional outline. The pressing sleeve 16 is coaxially arranged with the grip tube 01. The pressing sleeve 16 is closed at both ends, and one of its closed ends has a circular clearance hole 160 coaxially opened. The center rod 14 slides through the clearance hole 160, and the stop block 15 is located at the pressing... Inside the pressing sleeve 16, the stop block 15 can abut against the inner end wall of the pressing sleeve 16; the end of the pressing sleeve 16 near the grip tube 01 can simultaneously abut against multiple pressing blocks 07, and the length of the pressing sleeve 16 is greater than or equal to the length of the elongated hole 011; the purpose of this design is that when a perforated tube 04 extends out of the grip tube 01 and completes the perforation operation, the operator can press down the pressing sleeve 16 to simultaneously push the mandrel 03 and the remaining perforated tubes 04 out of the grip tube 01, thereby pushing out the fungal block inside the perforated tube 04 that has completed the perforation.

[0052] More specifically, it also includes a positioning ring 17, which is slidably and tightly fitted onto the outside of the grip tube 01. Two limiting rings 012 are integrally formed coaxially on the outer wall of the grip tube 01. The two end walls of the positioning ring 17 are slidably abutting against the two limiting rings 012. A rod body 170 is integrally formed on the positioning ring 17. The length direction of the rod body 170 is parallel to the axis of the positioning ring 17. A rod body 2 171 is integrally formed at the end of the rod body 170 away from the positioning ring 17. One end of the rod body 2 171 is connected to the end of the rod body 170 away from the positioning ring 17. Each pressing block 07 is integrally formed with a limiting ring 070.

[0053] When it is necessary to push one end of a perforated tube 04 out of the grip tube 01, the corresponding pressing block 07 needs to be pushed. When the pressing block 07 abuts against the inner wall of one end of the corresponding elongated hole 011, the operator can rotate the positioning ring 17 counterclockwise. When the positioning ring 17 rotates, it can drive the rod body 171 to move until the rod body 171 is inserted into the limiting ring 070 of the pressing block 07. Due to the elastic force of the spring 08, after releasing the pressing block 07, the outer wall of the rod body 171 can abut against the inner wall of the limiting ring 070. This design can fix the pressing block 07, ensuring that the pressing block 07 connected to the rod body 171 will not reset itself, and the extended perforated tube 04 will not retract automatically. The user does not need to keep pushing the pressing block 07.

[0054] More specifically, the punching assembly also includes connecting blocks 09, which are provided in multiples and are all located inside the grip tube 01. The ends of multiple connecting rods 05 away from the punched tube 04 are each fixed to one end of the multiple connecting blocks 09, and the ends of multiple guide rods 06 near the punched tube 04 are each fixed to the other end of the multiple connecting blocks 09. The connecting blocks 09 are provided with arc-shaped outer sidewalls 090, the center of which coincides with the center line of the grip tube 01. The arc-shaped outer sidewalls 090 can slide and fit tightly against the inner sidewall of the grip tube 01. The design of the connecting blocks 09 and the arc-shaped outer sidewalls 090 is, on the one hand, to ensure that the guide rods 06 and the connecting rods 05 can be reliably connected and fixed, and on the other hand, to improve the movement stability of the punched tube 04.

[0055] When using this drilling device:

[0056] First, the user selects a perforated tube 04 with a suitable aperture and pushes the pressing block 07 connected to the perforated tube 04. When the pressing block 07 is pressed against the end wall of the long hole 011 near the external threaded tube 010, one hand controls the pressing block 07 to remain stationary, while the other hand rotates the positioning ring 17 counterclockwise, so that the rod body 171 is inserted into the limiting ring 070 on the pressing block 07. After the above operation is completed, the end of the perforated tube 04 to be used that is away from the connecting rod 05 extends out from the inside of the grip tube 01 and remains in the extended state. The user can hold the grip tube 01 to punch holes in the mushroom cake.

[0057] Secondly, when the fungal block embedded inside the punch tube 04 needs to be ejected after the punching is completed, the user presses down on the sleeve 16, and the mandrel 03 and the rest of the punch tube 04 extend out from the inside of the grip tube 01, so that the fungal block embedded inside the punch tube 04 can be ejected smoothly.

[0058] Finally, after completing the drilling and needing to disinfect the drilled tube 04, the user screws the sealing tube 10 onto the external threaded tube 010, and then sequentially powers on the air pump 13 and the heating wire 12. After the heating wire 12 is powered on for a period of time, it is powered off, and the air pump 13 continues to work for a period of time. Once the temperature of the drilled tube 04 has dropped to room temperature, the sealing tube 10 can be removed.
