Description

Technical Field

[0001] The invention relates to the technical field of seat ring heaters, and in particular to a device for detecting whether a seat ring heater has leakage. Background Art

[0002] Smart toilets originated in the United States and are used for medical and elderly care. They were originally equipped with a warm water washing function. Later, bathroom companies in South Korea and Japan gradually introduced technology and began manufacturing, adding seat heating, warm water washing, warm air drying, sterilization and other functions. The principle of seat heating is to use a seat heater under the seat, and heat conduction from the seat heater is used to heat the seat. The existing seat heater lays a heating wire on aluminum foil and then fixes it under the seat to heat the seat. Since the heat generated by the heating wire is generated when electricity is turned on, and the aluminum foil is a conductive metal, and the toilet is located in a relatively humid bathroom, if leakage occurs, it is easy to cause injuries to people or even cause a fire. Summary of the invention

[0003] In order to solve the technical problems existing in the background technology, the present invention provides a device for detecting whether a seat heater has leakage.

[0006] As a further optimized solution of the present invention, the wire terminal is arranged at an end of the aluminum foil close to the end where the aluminum foil rotates relative to the toilet.

[0007] As a further optimized solution of the present invention, it also includes an anti-static structure, which includes a base, a conductive block, a conductive rope and a grounding block.

[0011] As a further optimized solution of the present invention, a second slide groove is opened on the grounding plate, and the grounding block is slidably installed in the second slide groove. When the grounding block slides in the second slide groove, it drives the conductive block to slide in the first slide groove.

[0012] As a further optimized solution of the present invention, it also includes an elastic member, which is fixed between a side wall of the second sliding groove and the grounding block, and the elastic member can be elastically deformed along the displacement direction of the sliding of the grounding block.

[0013] In some embodiments, the elastic member is a spring.

[0014] As a further optimized solution of the present invention, the outside of the conductive rope is coated with an insulating layer.

[0015] In the present invention, a device for detecting whether the seat ring heater has leakage is proposed.

[0026] like Figure 1-3 A device for detecting leakage of a seat heater shown in the figure comprises a grounding member 1, a wire 2, an indicator light 3, an anti-static structure 5 and a wire terminal 6, wherein:

[0027] One end of the wire terminal 6 is fixed to the aluminum foil 4 of the seat heater by welding, and the wire terminal 6 is arranged at the end of the aluminum foil 4 close to the rotation of the aluminum foil 4 relative to the toilet, and the other end of the wire terminal 6 is connected to the wire 2 by welding, and the indicator light 3 is connected in series to the wire 2, and the grounding member 1 is connected to the end of the wire 2 by welding, and the grounding member 1 is installed on the ground and grounded;

[0028] The anti-static structure 5 includes a base 55, a conductive block 50, a conductive rope 51 and a grounding block 52. The aluminum foil 4 is fixed on the base 55, the conductive block 50 is connected to the base 55, the conductive rope 51 is fixed between the conductive block 50 and the grounding block 52, and the grounding block 52 is grounded; the conductive block 50 is slidably mounted on the base 55 and can slide along the side of the base 55. A first slide groove 550 is opened on the side of the base 55, and the conductive block 50 is slidably mounted in the first slide groove 550;

[0029] The grounding assembly 5 further includes a grounding plate 53, on which a grounding block 52 is mounted, and a second slide groove 530 is formed on the grounding plate 53. The grounding block 52 is slidably mounted in the second slide groove 530. The grounding block 52 slides in the second slide groove 530 and drives the conductive block 50 to slide in the first slide groove 550. The grounding assembly 5 further includes an elastic member 54, which is fixed between a side wall of the second slide groove 530 and the grounding block 52, and the elastic member 54 can be elastically deformed along the displacement direction of the sliding of the grounding block 52, and the elastic member 54 is a spring.

[0030] The outside of the conductive rope 51 is covered with an insulating layer 7 .

[0031] In the working process of this embodiment: if the seat heater has leakage, the current is conducted to the ground through the aluminum foil 4, the wire terminal 6, the wire 2, the indicator light 3 and the grounding member 1. During the current conduction process, the indicator light emits a bright light when there is current passing through it, reminding the personnel that the seat heater has leakage.

[0032] Under the action of external force, the conductive rope 51 or the grounding block 52 is pulled to cause the grounding block to squeeze or stretch the elastic member 54. After the external force is removed, the elastic member 54 drives the grounding block 52 to reciprocate due to its own elastic force, thereby causing the conductive block 50 to reciprocate on the base 55, thereby removing static electricity at different positions on the base 55, thereby preventing the static electricity on the seat ring heater from affecting the detection accuracy of the device.

[0033] In this embodiment, in order to prevent the wire 2 from being pulled too much when the seat ring is rotated to be in a vertical state, thereby affecting the stability of the connection of the detection device, the wire terminal 6 is preferably arranged on the end of the aluminum foil 4 close to the end where the aluminum foil 4 rotates relative to the toilet.

[0034] Since the friction between the aluminum foil 4 and the toilet or human clothing can easily generate static electricity, the static electricity generated on the aluminum foil can easily affect the accuracy of the leakage detection device. Therefore, in order to facilitate the real-time removal of the static electricity of the seat heater, it is preferred in this embodiment to also include an anti-static structure 5, the anti-static structure 5 includes a base 55, a conductive block 50, a conductive rope 51 and a grounding block 52, the aluminum foil 4 is fixed on the base 55, the conductive block 50 is connected to the base 55, the conductive rope 51 is fixed between the conductive block 50 and the grounding block 52, the grounding block 52 is grounded, and the conductive particles generated by the friction between the base 55 and the toilet or human clothing are introduced into the ground along the conductive block 50, the conductive rope 51 and the grounding block 52, thereby avoiding the generation of static electricity affecting the accuracy of the detection of whether there is leakage.

[0035] In order to avoid generating a large pulling force on the conductive rope 51 during the rotation of the seat ring, in the present embodiment, preferably, the conductive block 50 is slidably mounted on the base 55 and can slide along the side of the base 55 .

[0036] Specifically in this embodiment, a first sliding groove 550 is opened on the side of the base 55 , and the conductive block 50 is slidably installed in the first sliding groove 550 .

[0037] In order to increase the connection of the grounding block 53 , in this embodiment, preferably, the grounding assembly 5 further includes a grounding plate 53 , and the grounding block 52 is mounted on the grounding plate 53 .

[0038] In order to facilitate the removal of static electricity, in the present embodiment, preferably, a second slide groove 530 is opened on the grounding plate 53, and the grounding block 52 is slidably installed in the second slide groove 530. When the grounding block 52 slides in the second slide groove 530, it drives the conductive block 50 to slide in the first slide groove 550. The position of the conductive block 50 can be moved by pulling the conductive rope 51 or the grounding block 52, thereby increasing the efficiency of static electricity removal.

[0039] In order to further increase the static electricity removal efficiency, it is preferred in the present embodiment to further include an elastic member 54, which is fixed between a side wall of the second slide groove 530 and the grounding block 52, and the elastic member 54 can be elastically deformed along the displacement direction of the sliding of the grounding block 52. Under the action of an external force, the conductive rope 51 or the grounding block 52 is pulled so that the grounding block squeezes or stretches the elastic member 54. After the external force is removed, the grounding block 52 is driven to perform reciprocating motion due to the elastic force of the elastic member 54 itself, thereby causing the conductive block 50 to perform reciprocating motion on the base 55, thereby removing static electricity at different positions on the base 55.

[0040] Specifically in this embodiment, the elastic member 54 is a spring.

[0041] In this embodiment, the conductive rope 51 is preferably a steel wire rope or other conductive wire with a certain degree of ductility, and the outside of the conductive rope 51 is coated with an insulating layer 7.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
