[0060] Figure 1 The structural schematic diagrams of the base, the positioning seat and the positioning top cover in an embodiment of this application are shown;

[0061] Figure 2 The structural schematic diagrams of the base, the positioning seat and the back panel in an embodiment of this application are shown.

[0062] Please refer to Figure 1 and Figure 2 and in combination refer to Figure 3, an embodiment of the present application provides a heating tube fixing seat 100 for a disinfection device 10, including a base 110, a positioning seat 120, and a positioning top cover 130.

[0063] Among them, the base 110 includes a bottom plate 111 and two side plates 112 arranged on opposite sides of the bottom plate 111. Both side plates 112 are used to penetrate and protrude from the back plate 200 of the disinfection device 10. The side plates 112 and the back plate 200 cooperate to form a first slot a. The positioning seat 120 is inserted into the first slot a to cooperate with the bottom plate 111 to clamp the back plate 200 of the disinfection device 10. In this way, the base 110 can be positioned on the back plate 200 of the disinfection device 10 to facilitate the installation of the heating tube 300.

[0064] The positioning top cover 130 is connected to one end of the side plate 112 away from the bottom plate 111 and is located above the positioning seat 120. A first limiting channel 140 is defined between the positioning top cover 130 and the positioning seat 120. The first limiting channel 140 is used to limit the axial movement and radial movement of a cylinder with a preset diameter, and the preset diameter is equal to the pipe diameter of the heating tube 300 to be fixed, so as to facilitate the end of the heating tube 300 to be limited in the first limiting channel 140.

[0065] It should be noted that the first limiting channel 140 formed between the positioning seat 120 and the positioning top cover 130 is located between the two side plates 112, and the connection between the side plates 112 and the positioning top cover 130 does not affect the application of the first limiting channel 140.

[0066] The use process of the heating tube fixing seat 100 is as follows: First, both side plates 112 can penetrate and protrude from the back plate 200 of the disinfection device 10, then the positioning seat 120 is inserted into the first slot a, so that the base 110 can be positioned on the back plate 200. Then, the end of the heating tube 300 is placed on the positioning seat 120. Finally, the positioning top cover 130 is connected to one end of the side plate 112 away from the bottom plate 111, and the end of the heating tube 300 is limited in the first limiting channel 140, so that the axial movement and radial movement of the heating tube 300 can be restricted. In this way, two heating tube fixing seats 100 can be respectively fixed at both ends of the heating tube 300 to fix the heating tube 300 well on the back plate 200. The heating tube fixing seat 100 is convenient for assembly, and components such as the base 110, the positioning seat 120, and the positioning top cover 130 are large in volume and small in quantity, which improves the installation efficiency of the heating tube 300 to a certain extent.

[0067] In some embodiments, the side plate 112 forms a second slot b. The positioning seat 120 is inserted into the first slot a along a first direction, and the positioning top cover 130 is inserted into the second slot b along a second direction and is connected to the side plate 112. Among them, the first direction and the second direction are not the same or opposite. During the assembly process, the positioning seat 120 and the positioning top cover 130 do not affect each other.

[0068] Wherein, the first direction is parallel to the central axis of the first limiting channel 140, so that after the positioning seat 120 is assembled, it is also convenient to install the heating tube 300.

[0069] Specifically, as in Figure 1 and Figure 2 In the illustrated embodiment, the first direction is opposite to the second direction, and both the first direction and the second direction are parallel to the bottom plate 111. The second slot b is located above the first slot a. In this way, during the assembly process, the positioning seat 120 and the positioning top cover 130 do not affect each other and are more convenient to assemble. Specifically, as in Figure 1 In the embodiment, the first direction is the rightward direction and the second direction is the leftward direction. That is to say, the positioning seat 120 is inserted into the first slot a to the right, and the positioning top cover 130 is inserted into the second slot to the left. The assembly process is relatively convenient, and the positioning seat 120 and the positioning top cover 130 do not affect each other during the assembly process.

[0070] In some embodiments, a convex portion 1111 is convexly provided on the upper surface of the bottom plate 111. The convex portion 1111 is used to penetrate and protrude from the back plate 200 of the disinfection device 10. The positioning seat 120 is formed with a groove 1201. In the first direction, the convex portion 1111 is inserted and matched with the groove 1201, so that the positioning seat 120 is fixed to the bottom plate 111, improving the reliability of the heating tube fixing seat 100 and also improving the installation reliability of the heating tube 300.

[0071] It should be noted that the convex portion 1111 is located in the first slot a, so that during the process of inserting the positioning seat 120 into the first slot a, the convex portion 1111 can also be inserted into the groove 1201 in the direction opposite to the first direction, which is convenient for assembly and also improves the installation reliability of the heating tube fixing seat 100.

[0072] In some embodiments, please refer to Figure 2 and in combination with Figure 4 On the surface of one side plate 112 facing the other side plate 112, a convex strip 1121 is convexly provided. The back plate 200, the side plate 112 and the convex strip 1121 enclose the first slot a, and the convex strip 1121 is formed with a first step portion 1122. The positioning seat 120 includes a base plate 121 and two side positioning plates 122 provided on opposite sides of the base plate 121. The side positioning plates 122 are formed with second step portions 1221, and the second step portions 1221 and the first step portions 1122 are joined in the first direction.

[0073] During the process of inserting the positioning seat 120 into the first slot a, the positioning seat 120 can be limited between the two side plates 112, or the second step portion 1221 and the first step portion 1122 can be engaged along the first direction, which can improve the connection firmness between the base 110 and the positioning seat 120, and further improve the installation reliability of the heating tube fixing seat 100.

[0074] Optionally, please refer to Figure 2 and Figure 4 , the second step portion 1221 and the rib 1121 are both Z-shaped, and the second step portion 1221 and the rib 1121 cooperate to limit each side positioning plate 122 between the back plate 200 and the corresponding rib 1121, which can limit the movement of the positioning seat 120 in the up and down direction, and can also better limit the radial movement of the heating tube 300 by using the positioning seat 120 and the positioning top cover 130.

[0075] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 , define a plane parallel to the third direction and intersecting the side plate 112 as the first virtual plane 113. Each side plate 112 is divided into a first side plate portion c and a second side plate portion d connected to each other by means of the first virtual plane 113. A first convex block 1123 extending in the fourth direction is provided on the side of the first side plate portion c of the side plate 112 away from the bottom plate 111. The first convex block 1123 is provided with a second convex block 1124 in the third direction. The second slot b is formed by enclosing the upper surface of the rib 1121, the first convex block 1123 and the second convex block 1124. Among them, the first direction, the third direction and the fourth direction are perpendicular to each other in pairs.

[0076] Combined with the foregoing back plate 200, side plates 112 and ribs 1121 enclosing the first slot a, it can be understood that the first slot a and the second slot b are spaced apart by the rib 1121 in the fourth direction, which is beneficial to the positioning seat 120 and the positioning top cover 130 not affecting each other during the assembly process, and is beneficial to installing the heating tube 300 in the first limiting channel 140 between the positioning seat 120 and the positioning top cover 130.

[0077] Specifically, in the embodiment shown in Figure 1 , the positioning seat 120 is inserted into the first slot a to the right, and the positioning top cover 130 is inserted into the second slot b to the left. The heating tube 300 arranged in the left-right direction can be conveniently installed in the first limiting channel 140.

[0078] In some embodiments, please refer to Figure 1 and Figure 4 , and in combination with reference to Figure 5, one end of the side positioning plate 122 away from the base plate 121 is provided with a third step portion 1222, and the third step portion 1222 is located on one side of the second step portion 1221 in the third direction. The upper surface of the rib 1121 is flush with the upper surface of the third step portion 1222, and in the third direction, the third step portion 1222 abuts against the rib 1121, and the third step portion 1222 also abuts against the upper surface of the rib 1121 and the upper surface of the third step portion 1222. Thus, after the positioning seat 120 is inserted into the first slot a along the first direction, the upper surface of the rib 1121 and the upper surface of the third step portion 1222 are connected to form a support surface sufficient to support the positioning top cover 130, so that the positioning top cover 130 inserted into the second slot b along the second direction can be better positioned and fixed on the base 110 and the positioning seat 120.

[0079] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 , the rib 1121, the third step portion 1222 and the second side plate portion d on the same side define a fourth step portion e. The two ends of the positioning top cover 130 in the third direction are provided with fifth step portions 131 that are in concave-convex fit with the fourth step portion e on the same side, so that in the third direction, the positioning top cover 130 abuts against the second side plate portion d, thereby limiting the positioning top cover 130 between the two second side plate portions d.

[0080] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 , the positioning top cover 130 is provided with a sixth step portion 132 that is in concave-convex fit with the second protrusion 1124, so that in the fourth direction, the positioning top cover 130 abuts against the second protrusion 1124. Since the second protrusion 1124 extends in the third direction, the positioning top cover 130 inserted into the second slot b abuts against the second protrusion 1124 on the same side along the fourth direction by means of the sixth step portion 132, which can limit the movement of the positioning top cover 130 in the fourth direction and can also better limit the radial movement of the heating tube 300 by using the positioning seat 120 and the positioning top cover 130.

[0081] Optionally, please refer to Figure 1 and Figure 3 , the second protrusion 1124 has a first joint surface, and the sixth step portion 132 has a first step surface 1321 that is docked with the first joint surface in the fourth direction.

[0082] In some embodiments, please refer to Figure 3, on both sides of the positioning top cover 130 in the third direction, there are seventh step portions 133 adapted to the second slots b on the same side, so that in the second direction, the positioning top cover 130 abuts against the first bump 1123, where the first direction is opposite to the second direction. That is to say, the positioning top cover 130 abuts against the first bump 1123 on the same side along the second direction by means of the seventh step portions 133 on both sides in the third direction. In addition, the positioning top cover 130 abuts against the first bump 1123 on the same side along the third direction by means of the seventh step portions 133 on both sides in the third direction, which can limit the positioning top cover 130 between the two side plates 112.

[0083] Optionally, please refer to Figure 1 and Figure 3 , the first bump 1123 has a second joint surface, and the seventh step portion 133 has a second step surface 1331 that docks with the second joint surface along the second direction. When the positioning top cover 130 is inserted into the second slot b along the second direction, the second step surface 1331 can abut against the second joint surface along the second direction. The first bump 1123 has a third joint surface, and the seventh step portion 133 has a third step surface 1332 that docks with the second joint surface along the third direction. When the positioning top cover 130 is inserted into the second slot b along the second direction, the third joint surface and the third step surface 1332 abut against each other along the third direction.

[0084] In some embodiments, please refer to Figure 2 and in combination with referring to Figure 5 , the second step portion 1221 has a continuously connected fourth step surface f, a fifth step surface g, and a sixth step surface h, where the fourth step surface f and the sixth step surface h are parallel to each other and both perpendicular to the fifth step surface g, and the rib 1121 has a seventh step surface that abuts against the fourth step surface f along the fourth direction, an eighth step surface that abuts against the fifth step surface g along the first direction, and a ninth step surface that abuts against the sixth step surface h along the fourth direction. When the side positioning plate 122 positioning seat 120 is inserted into the first slot a, it can also be limited between the back plate 200 and the corresponding rib 1121, which can limit the movement of the positioning seat 120 along the fourth direction and can also better limit the radial movement of the heating tube 300 by using the positioning seat 120 and the positioning top cover 130.

[0085] In some embodiments, please refer to Figure 5 and in combination with referring to Figure 6, on the base plate 121, there is a first positioning bump 123 located between two side positioning plates 122. The first positioning bump 123 has a first concave arc surface 1231, while the positioning top cover 130 is provided with a second positioning bump 134 located between seventh step portions 133 on both sides. The second positioning bump 134 has a second concave arc surface 1341. A first limiting channel 140 is formed between the first concave arc surface 1231 and the second concave arc surface 1341. It can be understood that the first concave arc surface 1231 and the second concave arc surface 1341 are joined to each other along the fourth direction, and the first limiting channel 140 formed between the first concave arc surface 1231 and the second concave arc surface 1341 is circular. Then, the heating tube fixing seat 100 can better fix the heating tube 300. At the same time, the end of the heating tube 300 can be in more contact with the heating tube fixing seat 100, and the heat dissipation effect is better.

[0086] In some embodiments, please refer to Figure 4 , and in combination with referring to Figure 7 , the heating tube fixing seat 100 further includes a metal retaining spring 150 provided on the bottom plate 111. The metal retaining spring 150 and the bottom plate 111 are insulated from each other. The metal retaining spring 150 passes through the back plate 200 and the positioning seat 120 of the disinfection device 10 in sequence, and is provided with a clamping portion 151. The clamping portion 151 is used for clamping with the wiring portion 301 of the heating tube 300. The metal retaining spring 150 can be fixed on the bottom plate 111, and the heating tube 300 fixed on the heating tube fixing seat 100 can be externally powered by using the metal retaining spring 150.

[0087] Specifically, please refer to Figure 4 , the positioning seat 120 is provided with a first aisle 124 for the clamping portion 151 to pass through, which facilitates the clamping portion 151 of the metal retaining spring 150 to pass through the first aisle 124 along the fourth direction and be connected to the heating tube 300.

[0088] Specifically, please refer to Figure 1 and Figure 7 , the metal retaining spring 150 includes two retaining spring portions 152 arranged at intervals in the third direction. One ends of the two retaining spring portions 152 extend along the fourth direction to form a clamping portion 151. A second limiting channel coaxial with the first limiting channel 140 is defined between the two clamping portions 151. It can be understood that the center lines of the first limiting channel 140 and the second limiting channel coincide with each other. While the heating tube 300 is fixed in the first limiting channel 140, the wiring portion 301 of the heating tube 300 is also clamped in the second limiting channel, which facilitates the external power supply of the wiring portion 301 of the heating tube 300 and can better fix the heating tube 300.

[0089] In some embodiments, the heating pipe fixing base 100 may further include an insulating gasket 160 disposed between the metal clip 150 and the bottom plate 111 to insulate the metal clip 150 from the bottom plate 111. The insulating gasket 160 may be used to isolate the metal clip 150 from the bottom plate 111 to insulate the metal clip 150 from the bottom plate 111.

[0090] The heating pipe fixing base 100 further includes an insulating screw 170 connected to the metal clip 150 and the bottom plate 111 respectively, and a wire 180 sleeved on the insulating screw 170, and the wire 180 is located between the metal clip 150 and the screw head of the insulating screw 170. In this way, when the metal clip 150 is installed on the bottom plate 111 by using the insulating screw 170, the wire 180 can be fixed between the metal clip 150 and the screw head of the insulating screw 170, and the wire 180 can be electrically connected to the heating pipe 300 through the metal clip 150, so that the heating pipe 300 can be connected to an external power source through the wire 180.

[0091] Specifically, the wire 180 has a connecting ring 181 sleeved on the insulating screw 170, the retaining spring portion 152 is connected to the bottom plate 111 through the insulating screw 170, the bottom plate 111 is provided with a threaded hole 1112 matching the insulating screw 170, the insulating gasket 160 is provided with a through hole 1601 for the insulating screw 170 to pass through, and the retaining spring portion 152 is provided with a mounting hole 1521. When installing the metal retaining spring 150, first sleeve the connecting ring 181 of the wire 180 on the insulating screw 170 (insulating screw 170). 0 head outer diameter is larger than the outer diameter of the connecting ring 181 of the wire 180, and the connecting ring 181 will not be separated from the head of the insulating screw 170), and the insulating gasket 160 is set between the bottom plate 111 and the retaining ring portion 152, and the through hole 1601 and the threaded hole 1112 are set in the center, and the mounting hole 1521 of the retaining ring portion 152 is aligned with the threaded hole 1112, and then the threaded section of the insulating screw 170 passes through the mounting hole 1521 and the through hole 1601 in sequence and is connected to the threaded hole 1112. The other clamping spring portion 152 can be fixed on the bottom plate 111 by the above method, and the ends of the two clamping spring portions 152 away from the bottom plate 111 form a clamping portion 151 coaxially arranged with the first limiting channel 140. If the wiring portion 301 of the heating pipe 300 is clamped on the clamping portion 151, the wire 180 can be electrically connected to the wiring portion 301 of the heating pipe 300 through the two clamping spring portions 152, and the clamping spring portion 152 and the bottom plate 111 are insulated from each other, so that the heating pipe fixing seat 100 will not be energized, which is safer.

[0092] Figure 8 A schematic diagram of installing the heating pipe 300 is shown.

[0093] See also Figure 8, A disinfection device 10 provided by an embodiment of the present application includes a heating tube 300 and two of the above-mentioned heating tube fixing seats 100. Both ends of the heating tube 300 are coaxially limited in the first limiting channels 140 of each heating tube fixing seat 100, so that both ends of the heating tube 300 can be fixed by one heating tube fixing seat 100 respectively.

[0094] In some embodiments, please refer to Figure 2 , and in combination with referring to Figure 9 , the disinfection device 10 further includes a back plate 200. The back plate 200 is provided with a first through hole 201 for two corresponding side plates 112 to pass through, a second through hole 202 for the clamping portion 151 to pass through, and a third through hole 203 for the protruding portion 1111 to pass through. The process of installing the heating tube 300 on the back plate 200 is as follows: Please refer to Figure 7 , first fix the metal snap spring 150 on the bottom plate 111, please refer to Figure 2 , then make the two side plates 112 of the base 110 pass through the corresponding first through holes 201, and make the clamping portion 151 pass through the second through hole 202, and make the protruding portion 1111 pass through the third through hole 203; please refer to again Figure 2 , then displace the positioning seat 120 along the first direction and insert it into the first slot a, and the positioning seat 120 is clamped on the bottom plate 111, so that the base 110 can be fixed on the back plate 200, and the third step portion 1222 of the positioning seat 120 and the rib 1121 of the side plate 112 are engaged along the third direction, so that the positioning seat 120 can be well limited and fixed between the two side plates 112; please refer to Figure 4 , then place the heating tube 300 on the first concave arc surface 1231 of the first positioning protrusion 123 of the positioning seat 120, and make the wiring portion 301 of the heating tube 300 be clamped in the second positioning channel between the two clamping portions 151; please refer to Figure 1 and Figure 4, then displace the positioning top cover 130 along the second direction and insert it into the second slot b, and make the seventh step portion 133 and the first bump 1123 fit with each other in a concave-convex manner, and make the sixth step portion 132 and the second bump 1124 fit with each other in a concave-convex manner, so that the positioning top cover 130 is concavely and convexly fitted and connected with each side plate 112; at the same time, make the fifth step portion 131 and the fourth step portion e fit with each other in a concave-convex manner. In this way, a part of the positioning top cover 130 can be limited between the two first bumps 1123, and when the positioning top cover 130 is inserted into the second slot b, the positioning top cover 130 can also be limited between the rib 1121 and the second bump 1124. Another part of the positioning top cover 130 abuts against the rib 1121 on the base 110 and the third step portion 1222 on the positioning seat 120 along the second direction by means of the fifth step portion 131 respectively, and another part of the positioning top cover 130 is limited between the two second side plate portions d. Then, the overall concave-convex fit of the positioning top cover 130, the base 110 and the positioning seat 120 makes the three better fixed together, and can also better limit the axial movement and radial movement of the heating tube 300 by using the base 110, the positioning seat 120 and the positioning top cover 130.

[0095] Optionally, the materials of the base 110, the positioning seat 120 and the positioning top cover 130 are all aluminum alloy materials, which have good heat dissipation effect, are not easily damaged, can reduce the transportation cost, improve the one-time qualification rate of workshop production and assembly, have high reliability, good durability and long service life.

[0096] Optionally, two protruding portions 1111 are provided on the bottom plate 111 at intervals along the third direction. Correspondingly, the number of the grooves 1201 on the positioning seat 120 is also two, and the number of the third through holes 203 is also two, which can better make the positioning seat 120 clamped to the bottom plate 111.

[0097] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
