[0032] Please refer to Figure 1 and Figure 2 , this embodiment provides a sealing structure 100 for the heater pipe orifice. The sealing structure 100 for the heater pipe orifice includes a heater housing 110, a core water pipe 120, a seal 130, and a locking member 140.

[0033] The heater housing 110 is configured with an orifice 111 for the core water pipe 120 to extend out; the seal 130 is sleeved on the core water pipe 120; the locking member 140 is sleeved on the core water pipe 120 and is connected to the heater housing 110 to press the seal 130 against the orifice 111.

[0034] Please refer to Figure 1 and Figure 2 , the working principle of the sealing structure 100 for the heater pipe orifice is as follows:

[0035] The beneficial effects of the embodiment of the present utility model are:

[0036] The sealing structure 100 for the heater pipe orifice includes a heater housing 110, a core water pipe 120, a seal 130, and a locking member 140. Among them, the heater housing 110 is configured with an orifice 111 for the core water pipe 120 to extend out, and the heater housing 110 and the core water pipe 120 can be structures in the prior art, that is, the sealing structure 100 for the heater pipe orifice can be improved on the basis of the structure in the prior art.

[0037] Specifically, when sealing, the seal 130 is sleeved on the core water pipe 120, the locking member 140 is sleeved on the core water pipe 120, and the locking member 140 is connected to the heater housing 110. Then, after the locking member 140 is connected to the heater housing 110, the seal 130 is pressed against the orifice 111. In such a setting method, a seal 130 is arranged at the orifice 111 of the heater housing 110 and is locked by the locking member 140, so that the seal 130 can be deformed at the orifice 111 under the action of the pressing force of the locking member 140. Furthermore, the deformed seal 130 can block the gap between the core water pipe 120 and the orifice 111, thereby improving its sealing performance.

[0038] In addition, in such a manner, the seal 130 forms a seal at the pipe orifice 111, which can increase the size of the contact end face of the seal 130, thereby reducing the installation difficulty in this way and improving the connection stability based on the connection between the locking member 140 and the housing.

[0039] In summary, the heater pipe orifice sealing structure 100 is applied to a heater. It has a simple structure and is easy to install. It can ensure the sealing performance while reducing the installation difficulty and improving the installation efficiency.

[0040] Furthermore, please refer to Figure 1 and Figure 2 . In this embodiment, as can be seen from the above, the heater pipe orifice sealing structure 100 is configured at the pipe orifice 111 of the heater housing 110 and sleeved on the core water pipe 120. Based on this, in order to increase the sealing performance on the outer periphery of the core water pipe 120, the interference fit between the seal 130 and the core water pipe 120 is adopted. In such a manner, the inner peripheral surface of the seal 130 is closely attached to the outer peripheral surface of the core water pipe 120, thereby improving the sealing performance between the contact surfaces.

[0041] Based on the above structure, please refer to Figure 1 and Figure 2 . In this embodiment, the locking member 140 is connected to the heater housing 110. Then, on the basis of the stable connection of the locking member 140, the seal 130 can maintain its sealing function under the pressing force of the locking member 140. Therefore, in order to simplify the connection difficulty of the locking member 140, the housing is provided with a protruding connecting pipe 150. The pipe orifice 111 is opened at the end of the connecting pipe 150, and the core water pipe 120 extends out from the connecting pipe 150; the locking member 140 is connected to the connecting pipe 150.

[0042] Through such a setting method, the locking member 140 sleeved on the core water pipe 120 can be conveniently connected to the connecting pipe 150, and there are various connection methods between the locking member 140 and the connecting pipe 150. In this embodiment, a plurality of first connection portions 141 are evenly spaced around the axis of the outer periphery of the locking member 140, and a plurality of second connection portions 151 are arranged around the axis of the connecting pipe 150; among them, the plurality of first connection portions 141 are connected to the plurality of second connection portions 151 in one-to-one correspondence.

[0043] That is, a plurality of first connecting portions 141 can be provided on the locking member 140, and the plurality of first connecting portions 141 are sequentially arranged at intervals around its axis to improve its stability during the connection process; and a plurality of second connecting portions 151 are provided on the outer periphery of the connecting pipe 150, so that the locking member 140 can be installed and locked by the one-to-one correspondence connection between the plurality of first connecting portions 141 and the plurality of second connecting portions 151.

[0044] In addition, please refer to Figure 1 and Figure 2 When configuring the above-mentioned first connecting portion 141 and second connecting portion 151, in this embodiment, one of the first connecting portion 141 and the second connecting portion 151 is a buckle, and the other is a clamping table that engages with the buckle. In this embodiment, the first connecting portion 141 is the buckle and the second connecting portion 151 is the clamping table. In this way, when installing the locking member 140, the locking member 140 can move along the axis of the core water pipe 120 toward the connecting pipe 150 to the position where the buckle and the clamping table are engaged. Therefore, the installation efficiency can be improved, the installation stability can be improved, and the installation difficulty can be reduced through such a method.

[0045] In addition, in other embodiments of the present invention, on the basis of adopting the above structure, different from the method that one of the above-mentioned first connecting portion 141 and second connecting portion 151 is a buckle and the other is a clamping table that engages with the buckle, an external thread threadedly connected to the locking member 140 can also be provided on the outer periphery of the connecting pipe 150. That is, the locking member 140 can be connected to the connecting pipe 150 by a threaded connection method. In this way, the installation efficiency can also be improved, the installation stability can be improved, and the installation difficulty can be reduced.

[0046] Furthermore, please refer to Figure 1 and Figure 2 In this embodiment, in order to increase the sealing performance of the sealing member 130 at the core water pipe 120 and the pipe orifice 111, when configuring the sealing member 130, the sealing member 130 can also include an annular sealing main body and an annular sealing protrusion;

[0047] The annular sealing main body is in interference fit with the core water pipe 120 and abuts against the pipe orifice 111 under the pressing action of the locking member 140; the annular sealing protrusion is on the side of the annular sealing main body facing the pipe orifice 111, and the annular sealing protrusion is pressed into the area between the pipe orifice 111 and the core water pipe 120 under the pressing action of the locking member 140.

[0048] That is, through such a setting method, the seal 130 can include an annular seal body for abutting against the end face of the pipe orifice 111 of the connecting pipe 150, and an annular seal protrusion that is pressed into the area between the pipe orifice 111 and the core water pipe 120 under the pressing action of the locking member 140. Furthermore, in this way, the seal 130 can not only maintain contact sealing with the end face of the pipe orifice 111, but also configure a corresponding deformable area so that it can be deformed directionally under the pressing action of the locking member 140 to be pressed into the area between the pipe orifice 111 and the core water pipe 120, thereby improving the sealing performance.

[0049] It should be noted that, based on the above-mentioned seal 130, along the radial direction of the annular seal protrusion, the inner circumference of the annular seal protrusion can be in interference fit with the outer peripheral wall of the core water pipe 120, and the outer circumference of the annular seal protrusion can be in interference fit with the inner peripheral wall of the connecting pipe 150, so as to increase the sealing performance in this way. In addition, in order to enable the annular seal protrusion to be deformed directionally into the area between the pipe orifice 111 and the core water pipe 120, the cross-section of the annular seal protrusion can be arc-shaped, that is, from the end of the annular seal protrusion far from the annular seal body to the end close to the annular seal body, the distance between its inner side and outer side gradually increases, so that the annular seal protrusion can be conveniently and quickly pressed into the area between the pipe orifice 111 and the core water pipe 120 in this way.

[0050] Furthermore, based on the above structure, in order to increase the sealing effect at the pipe orifice 111, the end face of the pipe orifice 111 is provided with multiple annular grooves along the axial direction of the connecting pipe 150. Through such a setting method, when the seal 130 contacts the pipe orifice 111, under the pressing action of the locking member 140, part of the seal 130 is deformed and pressed into the multiple annular grooves, so that multiple annular sealing rings can be formed, and thus the sealing effect can be improved.

[0051] Based on the above content, this embodiment also provides a heater, and the heater includes the above-mentioned heater pipe orifice sealing structure 100.

[0052] Please refer to Figure 1 and Figure 2 , by adopting the above-mentioned heater pipe orifice sealing structure 100, the heater can ensure the sealing performance while reducing its installation difficulty and improving the installation efficiency, thereby reducing the assembly cost.

[0053] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
