Description

Technical Field

[0001] This application relates to the field of foam processing technology, specifically to a foam cutting pen with a support. Background Technology

[0002] The use of electric heating and hot melting principles to cut fusible materials such as foam boards has become widespread, and foam cutting pens have emerged as a result. Foam cutting pens have cutting needles with heating wires. When electricity is applied, the needles begin to heat up and are used for advertising text production, handicrafts, art models, and various foam cutting and engraving work.

[0003] Currently, mainstream electrothermal cutting pens are heated and placed on a workbench, supported by a protruding structure at the front of the handle. However, this method of placement results in the cutting needle being too close to the table, posing a safety hazard. Some products on the market use a separate stand at the bottom of the foam cutting pen to support it, but this separate stand requires carrying separately, which is inconvenient.

[0017] The mounting body has an interconnected insertion slot, a first positioning slot, and a second positioning slot. The insertion slot is used to accommodate the insertion part, and both the first and second positioning slots can be used to accommodate the positioning part. When the positioning part is located in the first positioning slot, the support part can support the pen body when the cutting pen is placed on the workbench. When the positioning part is located in the second positioning slot, the support part is adjacent to the pen body.

[0018] In one embodiment, when the mounting body has a first positioning groove and a second positioning groove, the mounting body also has a limiting stop edge disposed along the first positioning groove and the second positioning groove.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] Reference Figure 1 and Figure 2 This application provides a foam cutting pen with a bracket, including a pen body 10, a pen needle assembly, a mounting body 30 and a support frame 40.

[0044] Specifically, the pen body 10 has a head end and a tail end; the pen body 10 is the main part of the cutting pen, and its interior can be used to install circuit boards and wires of the cutting pen, etc. The pen body 10 can include two detachable shells, which can be assembled into one piece by bolts or clips. The pen body 10 can be a cylindrical structure for easy gripping by the user. In some cases, the pen body 10 can be a polygonal prism structure. When the pen body 10 is a regular polygonal prism structure, it can improve the user's grip comfort.

[0045] The pen needle assembly is located at the head end of the pen body 10. The pen needle assembly has a connector 20 and a heating pen needle 21. The heating pen needle 21 is installed on the connector 20. The heating pen needle 21 is used to contact the foam and melt the foam. The heating pen needle 21 is equipped with a heating wire. When energized, the heating wire can heat up the heating pen needle 21. When the temperature reaches a certain level, the heating pen needle 21 can be operated through the pen body 10 to achieve the cutting of the foam to be processed.

[0046] Mounting body 30 is located on pen body 10; mounting body 30 may include two, with the two mounting bodies 30 located on opposite sides of pen body 10 respectively, and mounting body 30 and pen body 10 may be an integral component formed by injection molding.

[0047] The support frame 40 is connected to the mounting body 30 and is used to support the pen body 10 when the cutting pen is placed on the workbench. When the support frame 40 supports the pen body 10, the cutting pen can be tilted, and the heating pen needle 21 can be moved away from the workbench where it is placed.

[0048] By connecting the support frame 40 to the pen body 10 via the mounting body 30, the support frame 40 allows the cutting pen to be placed on the workbench, keeping the heating needle 21 away from the workbench. This increases the distance between the heating needle 21 and the workbench, solving the safety hazard of the heating needle 21 being too close to the workbench when the cutting pen is placed on the table only through the protruding structure of the pen body 10 near the heating needle 21. It also eliminates the need for the user to carry a separate stand to support the cutting pen, reducing the user's workload and improving the convenience of using the cutting pen.

[0049] In one embodiment of this application, reference is made to Figure 3 The support frame 40 includes a plug-in part 401, a positioning part 402, and a support part 403. The plug-in part 401 is used to be inserted into the mounting body 30; there are two plug-in parts 401, which are respectively disposed at both ends of the support frame 40.

[0050] The positioning part 402 is connected to the insertion part 401 and is used to cooperate with the insertion part 401 to install the support frame 40 on the mounting body 30. The positioning part 402 includes two parts that are respectively connected to the two insertion parts 401. When the support frame 40 is installed on the pen body 10, the positioning part 402 is located inside the mounting body 30, which can prevent the insertion part 401 from rotating relative to the pen body 10, so that the support frame 40 can achieve stable support for the pen body 10.

[0051] The support part 403 is connected to the positioning part 402 and is used to contact the workbench surface when the cutting pen is placed on the workbench surface; the two ends of the support part 403 are respectively connected to the two positioning parts 402, so that the two plug-in parts 401 and the two positioning parts 402 can be connected into one body to form the support frame 40, which can be a symmetrical structure component.

[0052] When the cutting pen is placed on the workbench, the support part 403 can contact the workbench, and the positioning part 402 can cooperate with the mounting body 30 to prevent the insertion part 401 from rotating relative to the mounting body 30 when the support frame 40 supports the pen body 10.

[0053] It should be noted that the plug-in part 401, the positioning part 402 and the support part 403 can be manufactured by integral molding, which makes the overall strength of the support frame 40 higher. However, in some cases, the plug-in part 401, the positioning part 402 and the support part 403 can also be assembled to cooperate with each other, which facilitates the replacement of parts of the support frame 40 after damage.

[0054] In this embodiment, the support part 403 may further include a diagonal brace section 4031 connected to the positioning part 402 and a contact section 4032 connecting the two diagonal brace sections 4031 together. The diagonal brace section 4031 may be inclined to both sides relative to the positioning part 402, thereby increasing the lateral dimension of the support part 403 and increasing the support stability of the support frame 40 for the pen body 10. The contact section 4032 may have a U-shaped structure. When the cutting pen is placed on the workbench, the support frame 40 can contact the workbench through the contact section 4032 to support the cutting pen.

[0055] In one embodiment of this application, reference is made to Figure 1 and Figure 2 The pen body 10 has a central axis a. When the cutting pen is placed on the workbench, the angle between the central axis a and the workbench is greater than 4° and less than 45°. By supporting the cutting pen with the support frame 40 and setting the angle between the central axis a of the pen body 10 and the workbench to a range greater than 4° and less than 45°, it is possible to maintain a safe distance between the heating pen needle 21 and the workbench, while also preventing the heating pen needle 21 from tilting too much, making it easy to accidentally touch, and preventing the cutting pen from having a high center of gravity, which would lead to poor stability. And / or,

[0056] Further reference Figure 3 The width of the support frame 40 is 0.9 to 1.8 times the width of the pen body 10. Specifically, when the support frame 40 has a symmetrical structure, its width direction is the connection direction between the centers of the two insertion parts 401, or the line direction connecting the centers of the two positioning parts 402, and the width of the support frame 40 is the distance between the two sides of the support part 403. When the pen body 10 has a cylindrical structure, its width is the diameter of the cylinder; when the pen body 10 has a regular polygonal prism structure, its width is the diameter of its circumscribed circle. Setting the width of the support frame 40 to 0.9 to 1.8 times the width of the pen body 10 ensures that the width of the support frame 40 is not too small relative to the pen body 10, providing stable support when the cutting pen is placed on a workbench, while also preventing the width of the support frame 40 from being too large relative to the pen body 10, making it convenient for users to carry.

[0057] In one embodiment of this application, reference is made to Figure 4 The mounting body 30 has an interconnected insertion groove 301 and a first positioning groove 302. The insertion groove 301 is used to accommodate the insertion part 401, and the first positioning groove 302 is used to accommodate the positioning part 402. Specifically, the insertion groove 301 is configured to fit the insertion part 401. The insertion part 401 can be a cylinder, and the insertion groove 301 is a corresponding circular hole. In order to prevent the cylindrical insertion part 401 from rotating in the circular hole-shaped insertion groove 301, the first positioning groove 302 is provided on the mounting body 30. When the positioning part 402 is located in the first positioning groove 302, it can prevent the insertion part 401 from rotating in the insertion groove 301, thereby realizing the support frame 40 supporting the pen body 10.

[0058] In one embodiment of this application, reference is made to Figure 2 and Figure 5 The pen body 10 has a connecting sleeve 11 at its tip to accommodate the connector 20. A connecting cell 101 is housed within the connecting sleeve 11, and the connector 20 has a cell insertion hole 201 corresponding to the connecting cell 101. Specifically, the connecting sleeve 11 and the pen body 10 can be an integral structural component. The connecting sleeve 11 can be made of plastic, and the connector 20 can be cylindrical. The connecting sleeve 11 is a circular sleeve that can be fitted onto the connector 20. Through this fitting, the heating pen needle 21 can be installed on the pen body 10, and the cell insertion hole 201 can be connected to the connecting cell 101. This enables the heating wire inside the heating pen needle 21 to conduct electricity with the circuitry within the pen body 10. After the surface of the heating pen needle 21 heats up, it can be used for processing foam.

[0059] It should be noted that the connector 20 is also provided with a retaining edge 203. The retaining edge 203 is arranged circumferentially along the edge of the connector 20. When the connector 20 and the connecting sleeve 11 are fully inserted, the retaining edge 203 abuts against the connecting sleeve 11. Thus, the user can determine whether the connector 20 and the connecting sleeve 11 are fully inserted by judging the relative position between the retaining edge 203 and the connecting sleeve 11.

[0060] In one embodiment of this application, further reference is made to Figure 2 and Figure 5 The connecting sleeve 11 is provided with at least one sub-foolproof part 102, and the connector 20 is provided with a female foolproof part 202 corresponding to the sub-foolproof part 102. Specifically, both the sub-foolproof part 102 and the female foolproof part 202 are arranged along the insertion direction of the connector 20 and the connecting sleeve 11. By inserting the connector 20 and the connecting sleeve 11 according to the corresponding positions of the sub-foolproof part 102 and the female foolproof part 202, the correct alignment of the connecting cell 101 and the cell socket 201 can be guaranteed, reducing the difficulty of connecting the connecting cell 101 and the cell socket 201.

[0061] It should be noted that the sub-foolproof part 102 can be configured as a raised shape or a recessed shape. When the sub-foolproof part 102 is raised, the mother foolproof part 202 is recessed. When the sub-foolproof part 102 is recessed, the mother foolproof part 202 is raised.

[0062] In addition, a pressing surface 107 may be provided inside the connecting sleeve 11. The pressing surface 107 is offset from the sub-foolproof part 102. When the connector 20 is inserted into the connecting sleeve 11, the pressing surface 107 can interact with the connector 20 to improve the stability of the insertion.

[0063] In one embodiment of this application, reference is made to Figures 1 to 5 The cutting pen operates on AC power. The pen body 10 is equipped with a switch 103 for controlling the working state of the cutting pen and a temperature adjustment button 104 for adjusting the temperature of the heating needle 21. The tail of the pen body 10 is equipped with an AC conductive socket 105. The switch 103 can control the power supply to or from the heating needle 21. The temperature adjustment button 104 can control the power of the heating wire inside the heating needle 21, thereby adjusting the temperature of the heating needle 21. The AC conductive socket 105 can connect the cutting pen to AC power to provide power input for the operation of the entire cutting pen.

[0064] Reference Figure 6 and Figure 7 This application also provides a foam cutting pen with a bracket, which has the same pen body 10, pen needle assembly, mounting body 30 and support frame 40 as the foam cutting pen with a bracket in the above embodiments.

[0065] Specifically, the pen body 10 has a head end and a tail end; the pen body 10 is the main part of the cutting pen, and its interior can be used to install circuit boards and cutting pen wires and other components. The pen body 10 can include two detachable shells, which can be assembled into one piece by bolts or clips. The pen body 10 can be a cylindrical structure for easy gripping by the user. In some cases, the pen body 10 can be a polygonal prism structure. When the pen body 10 is a regular polygonal prism structure, it can improve the user's grip comfort.

[0066] The pen needle assembly is located at the head end of the pen body 10. The pen needle assembly has a connector 20 and a heating pen needle 21. The heating pen needle 21 is installed on the connector 20. The heating pen needle 21 is used to contact the foam and melt the foam. The heating pen needle 21 is equipped with a heating wire. When energized, the heating wire can heat up the heating pen needle 21. When the temperature reaches a certain level, the heating pen needle 21 can be operated through the pen body 10 to achieve the cutting of the foam to be processed.

[0067] Mounting body 30 is located on pen body 10; mounting body 30 may include two, with the two mounting bodies 30 located on opposite sides of pen body 10 respectively, and mounting body 30 and pen body 10 may be an integral component formed by injection molding.

[0068] The support frame 40 is connected to the mounting body 30 and is used to support the pen body 10 when the cutting pen is placed on the workbench. When the support frame 40 supports the pen body 10, the cutting pen can be tilted, and the heating pen needle 21 can be moved away from the workbench where it is placed.

[0069] By connecting the support frame 40 to the pen body 10 via the mounting body 30, the support frame 40 allows the cutting pen to be placed on the workbench, keeping the heating needle 21 away from the workbench. This increases the distance between the heating needle 21 and the workbench, solving the safety hazard of the heating needle 21 being too close to the workbench when the cutting pen is placed on the table only through the protruding structure of the pen body 10 near the heating needle 21. It also eliminates the need for the user to carry a separate stand to support the cutting pen, reducing the user's workload and improving the convenience of using the cutting pen.

[0070] In one embodiment of this application, reference is made to Figure 8 The support frame 40 has the same insertion part 401, positioning part 402, and support part 403 as the support frame 40 in the above embodiment. The insertion part 401 is used to insert into the mounting body 30; there are two insertion parts 401, which are respectively disposed at both ends of the support frame 40.

[0071] The positioning part 402 is connected to the insertion part 401 and is used to cooperate with the insertion part 401 to install the support frame 40 on the mounting body 30. The positioning part 402 includes two parts that are respectively connected to the two insertion parts 401. When the support frame 40 is installed on the pen body 10, the positioning part 402 is located inside the mounting body 30, which can prevent the insertion part 401 from rotating relative to the pen body 10, so that the support frame 40 can achieve stable support for the pen body 10.

[0072] The support part 403 is connected to the positioning part 402 and is used to contact the workbench surface when the cutting pen is placed on the workbench surface; the two ends of the support part 403 are respectively connected to the two positioning parts 402, so that the two plug-in parts 401 and the two positioning parts 402 can be connected into one body to form the support frame 40, which can be a symmetrical structure component.

[0073] When the cutting pen is placed on the workbench, the support part 403 can contact the workbench, and the positioning part 402 can cooperate with the mounting body 30 to prevent the insertion part 401 from rotating relative to the mounting body 30 when the support frame 40 supports the pen body 10.

[0074] It should be noted that the plug-in part 401, the positioning part 402 and the support part 403 can be manufactured by integral molding, which makes the overall strength of the support frame 40 higher. However, in some cases, the plug-in part 401, the positioning part 402 and the support part 403 can also be assembled to cooperate with each other, which facilitates the replacement of parts of the support frame 40 after damage.

[0075] In this embodiment, the support part 403 may further include a diagonal brace section 4031 connected to the positioning part 402 and a contact section 4032 connecting the two diagonal brace sections 4031 together. The diagonal brace section 4031 may be inclined to both sides relative to the positioning part 402, thereby increasing the lateral dimension of the support part 403 and increasing the support stability of the support frame 40 for the pen body 10. The contact section 4032 may have a U-shaped structure. When the cutting pen is placed on the workbench, the support frame 40 can contact the workbench through the contact section 4032 to support the cutting pen.

[0076] In one embodiment of this application, reference is made to Figure 6 and Figure 7The pen body 10 has the same central axis a as in the above embodiment. When the cutting pen is placed on the workbench, the angle between the central axis a and the workbench is greater than 4° and less than 45°. By supporting the cutting pen with the support frame 40 and setting the angle between the central axis a of the pen body 10 and the workbench to be greater than 4° and less than 45°, it is possible to maintain a safe distance between the heating pen needle 21 and the workbench, and to prevent the heating pen needle 21 from tilting too much and being easily accidentally touched, as well as to prevent the cutting pen from having a high center of gravity and thus poor stability. And / or,

[0077] Further reference Figure 8 The width of the support frame 40 is 0.9 to 1.8 times the width of the pen body 10. Specifically, when the support frame 40 has a symmetrical structure, its width direction is the connection direction between the centers of the two insertion parts 401, or the line direction connecting the centers of the two positioning parts 402, and the width of the support frame 40 is the distance between the two sides of the support part 403. When the pen body 10 has a cylindrical structure, its width is the diameter of the cylinder; when the pen body 10 has a regular polygonal prism structure, its width is the diameter of its circumscribed circle. Setting the width of the support frame 40 to 0.9 to 1.8 times the width of the pen body 10 ensures that the width of the support frame 40 is not too small relative to the pen body 10, providing stable support when the cutting pen is placed on a workbench, while also preventing the width of the support frame 40 from being too large relative to the pen body 10, making it convenient for users to carry.

[0078] In one embodiment of this application, reference is made to Figure 9 and Figure 10 The structure of the mounting body 30 in this embodiment is different from that in the above embodiments. The mounting body 30 in this embodiment has a plug-in groove 301, a first positioning groove 302 and a second positioning groove 303 that are interconnected. The plug-in groove 301 is used to accommodate the plug-in part 401. The first positioning groove 302 and the second positioning groove 303 can both be used to accommodate the positioning part 402. When the positioning part 402 is located in the first positioning groove 302, the support part 403 can support the pen body 10 when the cutting pen is placed on the workbench. When the positioning part 402 is located in the second positioning groove 303, the support part 403 is adjacent to the pen body 10. Specifically, the insertion slot 301 is configured to fit the insertion part 401. The insertion part 401 can be a cylinder, and the insertion slot 301 is a corresponding circular hole. In order to prevent the cylindrical insertion part 401 from rotating in the circular hole-shaped insertion slot 301, a first positioning slot 302 is provided on the mounting body 30. The positioning part 402 is located in the first positioning slot 302, which can prevent the insertion part 401 from rotating in the insertion slot 301, thereby realizing the support frame 40 supporting the pen body 10.

[0079] In addition, the positioning part 402 can also be located in the second positioning groove 303. When the positioning part 402 is located in the second positioning groove 303, the support frame 40 is adjacent to the pen body 10. In practical applications, it can be in close contact with the pen body 10. When the cutting pen is picked up from the workbench, the positioning part 402 can be moved from the first positioning groove 302 to the second positioning groove 303, and the support frame 40 can be adjusted from the supporting state to the storage state to avoid the support frame 40 affecting the user's operation of the cutting pen.

[0080] It should be noted that the support frame 40 can be made of elastic material. The position of the positioning part 402 can be adjusted from the first positioning groove 302 and the second positioning groove 303 by the elastic deformation of the support frame 40, so as to switch the support frame 40 from the supporting state to the storage state, or switch the support frame 40 from the storage state to the supporting state.

[0081] In one embodiment of this application, reference is made to Figure 10 When the mounting body 30 has a first positioning groove 302 and a second positioning groove 303, the mounting body 30 also has a limiting stop 304 provided along the first positioning groove 302 and the second positioning groove 303. Specifically, the limiting stop 304 protrudes relative to the mounting body 30, the first positioning groove 302 is provided on one side of the limiting stop 304, the second positioning groove 303 is provided on the other side of the limiting stop 304, and the positioning part 402 can move in the area inside the limiting stop 304, making it convenient for the user to adjust the support frame 40 between the supported state and the stored state.

[0082] In one embodiment of this application, reference is made to Figure 7 and Figure 11 In this embodiment, the pen body 10 has a connecting chamber 12 at its tip for accommodating the connector 20. A connecting cell 101 is disposed inside the connecting chamber 12, and the connector 20 is provided with a cell insertion hole 201 corresponding to the connecting cell 101. Specifically, the connector 20 can be cylindrical, and the connecting chamber 12 is a circular cavity that can be fitted onto the connector 20. By fitting the two together, the heating pen needle 21 can be installed on the pen body 10, and the cell insertion hole 201 can be connected to the connecting cell 101, so that the heating wire inside the heating pen needle 21 is connected to the circuit inside the pen body 10. After the surface of the heating pen needle 21 is heated, it can be used for processing foam.

[0083] It should be noted that the connector 20 is also provided with a guard edge 203. The guard edge 203 is arranged circumferentially along the edge of the connector 20. When the connector 20 is fully inserted into the connecting chamber 12, the guard edge 203 abuts against the pen body 10 on one side of the connecting chamber 12. Thus, the user can judge whether the connector 20 and the connecting chamber 12 are fully inserted by judging the relative position between the guard edge 203 and the pen body 10 on one side of the connecting chamber 12.

[0084] In one embodiment of this application, further reference is made to Figure 7 and Figure 11 The connection chamber 12 is provided with at least one sub-foolproof part 102, and the connector 20 is provided with a female foolproof part 202 corresponding to the sub-foolproof part 102. Specifically, both the sub-foolproof part 102 and the female foolproof part 202 are arranged along the insertion direction of the connector 20 and the connection chamber 12. By inserting the connector 20 into the connection chamber 12 according to the corresponding orientation of the sub-foolproof part 102 and the female foolproof part 202, the correct alignment of the battery cell 101 and the battery cell socket 201 can be ensured, reducing the difficulty of connecting the battery cell 101 and the battery cell socket 201.

[0085] It should be noted that the sub-foolproof part 102 can be configured as a raised shape or a recessed shape. When the sub-foolproof part 102 is raised, the mother foolproof part 202 is recessed. When the sub-foolproof part 102 is recessed, the mother foolproof part 202 is raised.

[0086] In addition, an indicator mark 108 can be provided at one end of the pen body 10 located in the connecting chamber 12. The indicator mark 108 corresponds to the position of the sub-foolproof part 102. Through the indicator mark 108, the user can easily know the position of the sub-foolproof part 102, which facilitates the corresponding insertion of the sub-foolproof part 102 and the mother-foolproof part 202, reducing the assembly difficulty of the cutting pen.

[0087] In one embodiment of this application, reference is made to Figures 6 to 11 The cutting pen operates using direct current. A switch 103 is provided on the pen body 10 to control the working state of the cutting pen, and a DC conductive socket 106 is provided at the tail of the pen body 10. The switch 103 can control the power supply to or from the heating pen needle 21, and the DC conductive socket 106 can connect the cutting pen to DC power to provide power input for the operation of the entire cutting pen.
