[0081] In the existing hot melt adhesive generating device, the host structure includes multiple components. The assembly between each component is not only cumbersome, with low assembly efficiency and easy to loosen, but also makes the structure not compact enough and occupies a relatively large space.

[0082] Based on this, the present application proposes a host structure and its assembly method to solve the problems of the existing host structure being complex, difficult to assemble, not compact, and prone to loosening.

[0083] Please refer to Figures 1 to 16 , on the one hand, the present invention provides a host structure for a hot melt adhesive generating device, including:

[0084] An inner support assembly 10, which includes a support. The support includes a first mounting seat 111 and a second mounting seat 112 located below the first mounting seat 111. The first mounting seat 111 extends downward to form a first side wall 1111. The first side wall 1111 is connected to the second mounting seat 112 and encloses to form a battery compartment 12 for placing a battery 13. And the side surface of the first side wall 1111 has an opening so that the battery compartment 12 has a compartment opening for the battery 13 to enter and exit; Circuit board mounting grooves are provided on the first mounting seat 111 and the second mounting seat 112; The first mounting seat 111 is provided with a third mounting groove 1113;

[0085] A main board assembly 20, which includes a circuit board. The circuit board is installed in the circuit board mounting grooves of the first mounting seat 111 and the second mounting seat 112, and the circuit board blocks the compartment opening of the battery compartment 12 to prevent the battery from coming out of the battery compartment 12;

[0086] A fixing bracket 30, which is assembled and connected to the second mounting seat 112. The fixing bracket 30 has a fourth mounting groove 31 located below the third mounting groove 1113;

[0087] A heating element assembly 40, one end of which is assembled in the third mounting groove 1113, and the other end is assembled in the fourth mounting groove 31.

[0088] In this application, the main body structure includes an inner support assembly 10, a main board assembly 20, a fixing bracket 30, and a heating element assembly 40. The inner support assembly 10 has a first mounting seat 111 and a second mounting seat 112 distributed vertically, and a battery compartment 12 disposed between the first mounting seat 111 and the second mounting seat 112. Circuit board mounting grooves for placing the circuit board are also provided on the first mounting seat 111 and the second mounting seat 112. During implementation, the battery 13 is placed in the battery compartment 12, the circuit board of the main board assembly 20 is placed in the circuit board mounting groove, and the circuit board blocks the opening of the battery compartment 12 to prevent the battery 13 from coming out of the battery compartment 12. The fixing bracket 30 is assembled and connected to the second mounting seat 112. One end of the heating element assembly 40 is assembled in the third mounting groove 1113 of the first mounting seat 111, and the other end is assembled in the fourth mounting groove 31 of the fixing bracket 30. Through the above settings, the main board assembly 20 is simple to disassemble and assemble, firmly and stably assembled, buried in the inner support assembly 10, more compact with the battery 13, and can prevent the battery 13 from coming out of the battery compartment 12 through the circuit board without additionally setting a door for the battery compartment 12. By assembling the fixing bracket 30 on the second mounting seat 112, a structure for installing the heating element assembly 40 can be formed with the first mounting seat 111 of the inner support assembly 10. At this time, the heating element assembly 40 can be installed between the fixing bracket 30 and the inner support assembly 10, and the heating element assembly 40 can be realized through the cooperation of the fixing bracket 30 and the inner support assembly 10. At this time, the inner support assembly 10, the main board assembly 20, the fixing bracket 30, and the heating element assembly 40 are stably, firmly, and compactly assembled and connected, occupying a small space. The first mounting seat 111, the first side wall 1111, and the second mounting seat 112 form the battery compartment 12, and the battery 13 is placed in the battery compartment 12. There is no need to separately set a separate battery compartment, which occupies a small space, is simple to assemble, and is not easy to fall out. The main body structure of the present invention has a simple structure and is simple to assemble. Bolts can be avoided for fixing, the fixing and assembly processes are simple, the structures of all components are tightly installed and do not loosen, and the problem of large space occupation is solved.

[0089] In some embodiments, the side surface of the first side wall 1111 has an opening, and the opening is provided on a partial side surface of the first side wall 1111 to form an entrance and exit for the battery 13 to enter and exit the battery compartment 12 through the opening. The opening can be much larger than the size of the battery 13, so that on the one hand, materials can be saved as much as possible, and on the other hand, it is more conducive to the heat dissipation of the battery 13. It only needs to cooperate with the circuit board to block the opening of the battery compartment 12 to ensure that the battery 13 cannot accidentally fall out of the battery compartment 12. Based on this, the circuit board does not need to block the entire opening of the battery compartment 12.

[0090] In some embodiments, the circuit board mounting groove includes a first mounting groove 1112 formed at the bottom of the first mounting base 111, a second mounting groove 1121 formed on the second mounting base 112 and disposed opposite to the first mounting groove 1112, and a fifth mounting groove 1122 formed on the second mounting base 112 and communicating with the second mounting groove 1121; the circuit board includes a first circuit board 21 and a second circuit board 22, the first circuit board 21 and the second circuit board 22 are assembled and connected, the upper end of the first circuit board 21 is mounted in the first mounting groove 1112, the lower end is mounted in the second mounting groove 1121, the second circuit board 22 is located in the fifth mounting groove 1122, and the first circuit board 21 blocks the opening of the battery compartment 12 to prevent the battery 13 from coming out of the battery compartment 12. By providing the first mounting groove 111 and the second mounting groove 112, and disposing the first circuit board 21 and the second circuit board 22 in the first mounting groove 1112, the second mounting groove 1121 and the fifth mounting groove 1122 respectively, and the first circuit board 21 and the second circuit board 22 are assembled and connected, the connection between the bracket and the circuit board is firm and not easy to loosen, that is, the first circuit board 21 and the second circuit board 22 are stable and not loose; at the same time, through the concave-convex inlay structure between the circuit board and the mounting groove and the assembly connection between the first circuit board 21 and the second circuit board 22, the first circuit board 21 and the second circuit board 22 are disposed in the cavity structure of the bracket, which is convenient for shortening the longitudinal height of the product, making the structure more compact, and helping to solve the problem of large space occupation.

[0091] It can be understood that the partial location of the first circuit board 21 in the mounting groove does not mean that all end faces and / or side faces of the first circuit board 21 are in contact with the side wall of the mounting groove. In a preferred embodiment, at least part of the end face and / or side face of the end of the first circuit board 21 is not in contact with the side wall of the mounting groove and a gap is left to adapt to the assembly error and eliminate the extrusion deformation of the circuit board caused by the assembly error through this gap, and leave a margin for the thermal expansion and contraction of the circuit board to prevent its extrusion deformation.

[0092] In some preferred embodiments, by way of example, both the first mounting groove 1112 and the second mounting groove 1121 are vertical grooves, and the first mounting groove 1112 and the second mounting groove 1121 are located at the side position of the battery compartment 12. Two end portions of the first circuit board 21 are respectively located in the first mounting groove 1112 and the second mounting groove 1121. The fifth mounting groove 1122 is a horizontal groove and is located below the battery compartment 12. At this time, the second circuit board 22 is horizontally arranged and located below the battery compartment 12, the first circuit board 21 is vertically arranged and located between the battery compartment 12 and the heating element assembly 40. The first circuit board 21 and the second circuit board 22 are perpendicular to each other and are connected by mutual assembly to achieve mutual limiting of the first circuit board 21 and the second circuit board 22, enhance the connection strength between the first circuit board 21 and the second circuit board 22, thereby further enhancing the connection strength between the circuit board and the bracket, ensuring that the bracket and the circuit board are firmly connected and not easily loosened; at the same time, the structure can be made more compact, which helps to solve the problem of large space occupation.

[0093] In some embodiments, by way of example, the groove wall of the fifth mounting groove 1122 is provided with a hollow structure, so that the upper and lower groove walls of the fifth mounting groove 1122 have a hollow structure, enabling the fifth mounting groove 1122 to have a certain elastic deformation ability, facilitating the installation of the second circuit board 22, and at the same time reducing the contact area between the fifth mounting groove 1122 and the second circuit board 22, enhancing heat dissipation. A butting portion is provided at the notch of the fifth mounting groove 1122 for butting against the outer side edge of the second circuit board 22 to achieve lateral limiting of the second circuit board 22 and prevent the second circuit board 22 from accidentally disengaging from the fifth mounting groove 1122.

[0094] Preferably, the material of the inner frame assembly 10 is PPSU, preferably black, and the main body is mainly formed by an injection molding process. By way of example, the first mounting seat 111, the first side wall 1111 and the second mounting seat are made of PPSU material and are integrally formed by an injection molding process to maintain the strength and stability of the bracket.

[0095] In some embodiments, the first circuit board 21 and the second circuit board 22 are connected by assembly of a slot 211 and a pin 221. The assembly method of the slot 211 and the pin 221 is simple to disassemble and assemble, firmly and stably assembled, simple to implement, and has an obvious limiting effect. By way of example, a pin 221 is provided at the end of the second circuit board 22, and a slot 211 corresponding to the pin 221 is provided at the end of the first circuit board 21 close to the second circuit board 22. The pin 221 is inserted into the slot 211, and the first circuit board 21 is connected to the second circuit board 22 by assembly of the slot 211 and the pin 221. Preferably, there are multiple slots 211, and the number of pins 221 is the same as that of the slots 211. The cooperation of the multiple slots 211 and the pins 221 in assembly connection makes the connection more stable, firm, not loose and not shaking.

[0096] In some embodiments, preferably, a printed circuit is provided on the first circuit board 21, and conductive terminals are provided on the pins 221 of the second circuit board 22. The pins 221 are inserted into the slots 211, and the conductive terminals on the pins 221 are in contact with the printed circuit of the first circuit board 21. The conductive terminals on the pins 221 are in contact with the printed circuit of the first circuit board 21, thereby realizing electrical connection between the first circuit board 21 and the second circuit board 22. When assembling the first circuit board 21 and the second circuit board 22, first, through the mutual cooperation of the pins 221 and the slots 211, the positioning between the first circuit board 21 and the second circuit board 22 is realized to ensure that the conductive terminals are aligned with the printed circuit. Then, the electrical terminals and the printed circuit are welded and fixed to ensure a stable connection and electrical connection between the electrical terminals and the printed circuit. By setting the mutual cooperation of the pins 221 and the slots 211, the conductive terminals and the printed circuit are aligned during the welding process. And because of the mutual limitation between the pins 221 and the slots 211, the conductive terminals and the printed circuit will not shift during the welding process, ensuring the smooth completion of the welding. In addition, the cooperation between the pins 221 and the slots 211 makes the cooperation between the first circuit board 21 and the second circuit board 22 more firm, avoiding relative shaking between the first circuit board 21 and the second circuit board 22, avoiding the separation or falling off of the solder between the conductive terminals and the printed circuit, and avoiding poor contact between the two.

[0097] In some embodiments, the main board assembly 20 further includes a motor 23, a differential pressure sensor 25, and a sealing silicone sleeve 24. The motor 23 and the differential pressure sensor 25 are welded to the first circuit board 22, and then the sealing silicone sleeve 24 is sleeved on the differential pressure sensor. The sealing silicone sleeve 24 is provided with an air passage (not shown) communicating with the differential pressure sensor. The sealing silicone sleeve 24 is made by injection molding.

[0098] In some embodiments, the second mounting seat 112 has a fourth side wall 1123, and a second fastening portion 1124 is provided on the fourth side wall; the fixing bracket 30 has a second side wall 32 and a third side wall 33. The second side wall 32 is integrally annular and forms a fourth mounting groove 31. The third side wall 33 surrounds the outside of the second side wall 32, and a clamping groove 34 is formed between the third side wall 33 and the second side wall 32. A first fastening portion 35 is provided in the clamping groove 34; the fourth side wall 1123 is inserted into the insertion groove 34, and the first fastening portion 35 is fastened and connected to the second fastening portion 1124. By inserting the fourth side wall 1123 into the insertion groove 34 and fastening the first fastening portion 35 and the second fastening portion 1124, the assembly connection between the fixing bracket 30 and the second mounting seat 112 is realized, that is, the reliable connection between the fixing bracket 30 and the bracket is realized.

[0149] Set the lower sealing sleeve 41 on the lower support 43 of the vacuum tube, and then set the vacuum tube 47 outside the lower sealing sleeve 41. Since the lower sealing sleeve 41 is relatively soft, first set the lower sealing sleeve 41 on the lower support 43 of the vacuum tube. The lower support 43 of the vacuum tube has a supporting effect on the lower sealing sleeve 41. When the vacuum tube 47 is sleeved outside the lower sealing sleeve 41, due to the support of the lower support 43 of the vacuum tube, the lower sealing sleeve 41 will not deform inward excessively; if the vacuum tube 47 is first sleeved outside the lower sealing sleeve 41 and then the lower sealing sleeve 41 is set on the lower support 43 of the vacuum tube, it will be difficult to set it in at this time due to the inward excessive deformation of the lower sealing sleeve 41. Similarly, set the upper sealing sleeve 46 on one end of the upper support 45 of the heating tube, and then set the other end of the upper support 45 of the heating tube outside the upper end of the heating tube 44. At this time, the upper sealing sleeve 46 is sleeved inside the upper end of the vacuum tube 47 together. Since the upper sealing sleeve 46 is relatively soft, the upper support 45 of the heating tube has a supporting effect on the upper sealing sleeve 46. When the upper sealing sleeve 46 is sleeved inside the upper end of the vacuum tube 47, the upper sealing sleeve 46 will not deform inward excessively; if one end of the upper support 45 of the heating tube is first sleeved outside the upper end of the heating tube 44 and then the upper sealing sleeve 46 is sleeved, it will be difficult to set it in at this time due to the inward excessive deformation of the upper sealing sleeve 46.

[0150] For the assembly method of the main machine structure of the present invention, each component is pre-assembled on different production lines and then assembled in combination. The cooperation process between components is more simplified. And through the specific cooperation relationship between components, the assembly steps can be reduced, the production efficiency of the product can be improved, the main machine structure is simplified, the assembly is simplified, the structure is compact and does not loosen, occupies less space, the assembly is firm and stable, and the cumbersome process of fixing with screws can be avoided as much as possible.
