Description

Technical Field

[0001] The utility model relates to the technical field of toilet seat heaters, and particularly relates to a heating film for a toilet seat. Background Art

[0002] With the improvement of living quality, intelligent toilets are increasingly favored by consumers due to their convenience and comfort. Among them, the seat heating function, as one of the standard configurations of intelligent toilets, directly affects the user experience. However, the heating films of common toilet seats on the market often have problems such as uneven heating, local overheating or overcooling, which not only reduce the comfort of use but also may lead to increased energy consumption and safety hazards due to heat concentration.

[0003] For example, the Chinese patent with the patent number CN209315719U discloses a seat of an intelligent toilet, which includes a skeleton main body and a plastic surface layer wrapping the skeleton main body. The skeleton main body includes a metal template, a heating component and a sitting-down induction component arranged on the metal template; the plastic surface layer wraps the skeleton main body through an injection molding process; the heating component includes a resistive heating wire group and an aluminum foil with an adhesive, and the resistive heating wire group is positioned on the side of the aluminum foil facing away from the adhesive, and the heating component is pasted on the surface of the metal template through the adhesive of the aluminum foil. However, there is no strict requirement for the layout of the resistive heating wire group on the aluminum foil with an adhesive in the seat of the intelligent toilet, and the formed heating component still has uneven heating, with problems of local overheating or overcooling, which not only reduces the comfort of use but also may lead to increased energy consumption and safety hazards due to heat concentration.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following further describes the specific embodiments of the present utility model in detail with reference to the drawings and examples. The following examples are used to illustrate the present utility model, but not to limit the scope of the present utility model.

[0026] As Figure 1As shown in the figure, a heating film for a toilet seat ring is installed in the shell of the toilet seat ring in a matching manner; the entire heating film of the toilet seat ring can be conveniently embedded in the shell of the toilet seat ring, and the heating function is realized through electrical connection, and the installation process is simple and fast. The heating film of the toilet seat ring includes an aluminum foil film 1, a heating wire 2 and a hot melt adhesive; the aluminum foil film 1 can be connected to the inner cavity of the shell of the toilet seat ring in a matching manner; the aluminum foil film 1 serves as the base for heat conduction, and its special structural design provides the basis for the uniform layout of the heating wire 2. Preferably, the thickness of the aluminum foil film 1 is 1-2 mm. The heating wire 2 is wound between the two aluminum foil films 1 through the hot melt adhesive; the heating wire 2 is preferably made of nickel-chromium alloy and has good heating efficiency. In addition, the heating wire 2 is arranged on the aluminum foil film 1 according to a specific pattern, and heat is generated by passing an electric current; the hot melt adhesive is used to fix the heating wire 2 and the aluminum foil film 1 to ensure the stability and safety of the structure. The aluminum foil film 1 has an inner ring edge 11 and an outer ring edge 12; such a clear design of the inner ring edge 11 and the outer ring edge 12 makes the layout of the heating wire 2 have a clear boundary and reference. The good heat conduction performance of the aluminum foil film 1 ensures that heat can be quickly and evenly distributed on the entire surface of the seat ring. The heating wire 2 includes a side-edge heating section 21, a left coiled heating section 22, a right coiled heating section 23 and a rear coiled heating section 24; the side-edge heating section 21 extends along the inner ring edge 11; the left coiled heating section 22 is coiled between the left side close to the side-edge heating section 21 and the left side close to the outer ring edge 12; the right coiled heating section 23 is coiled between the right side close to the side-edge heating section 21 and the right side close to the outer ring edge 12; the rear coiled heating section 24 is coiled between the upper side close to the side-edge heating section 21 and the upper side close to the outer ring edge 12.

[0027] According to the internal shape of the shell of the toilet seat ring, the heating film of the toilet seat ring is set. On the basis of the aluminum foil film 1, the heating wire 2 and the hot melt adhesive, the heating wire 2 is improved. By setting the side-edge heating section 21, the left coiled heating section 22, the right coiled heating section 23 and the rear coiled heating section 24 to form the heating wire 2, first the side-edge heating section 21 is extended along the inner ring edge 11 to form a basic heating zone similar to a ring, effectively avoiding the cold feeling at the edge of the seat ring; then the left coiled heating section 22, the right coiled heating section 23 and the rear coiled heating section 24 are coiled between the left side, the right side and the rear side of the aluminum foil film 1 close to the side-edge heating section 21 and close to the outer ring edge 12. Through this unique layout design of the heating wire 2, not only the heating area is increased, but also the heat is evenly distributed by the coiling method, thus realizing the uniform heating of the surface of the seat ring, eliminating the phenomenon of local overheating or overcooling, effectively solving the problem of local overheating or overcooling in the traditional heating film, improving the user's comfort, and at the same time, the uniform heating reduces unnecessary energy consumption waste, making the entire heating process more energy-efficient.

[0028] Preferably, the left coiled heating section 22, the edge heating section 21, the right coiled heating section 23 and the rear coiled heating section 24 are connected in series in sequence. By reasonably arranging the path of the heating wire 2, uniform heating of the seat surface is achieved, eliminating the phenomenon of local overheating or overcooling, improving the user's comfort. At the same time, uniform heating reduces unnecessary energy consumption waste, making the entire heating process more energy-efficient.

[0029] In the embodiment, an aluminum foil cut 13 penetrating through the outer ring edge 12 and the inner ring edge 11 is provided at the front end of the aluminum foil film 1. When a user sits on the seat, the force on the front end of the seat on the person is generally small and the contact is also less. Thus, providing the aluminum foil cut 13 at the front end of the aluminum foil film 1 can reduce the material design of the aluminum foil film 1 and the path arrangement of the heating wire 2, which is beneficial to cost reduction.

[0030] Preferably, the left side and the right side of the aluminum foil cut 13 are horizontally arranged; the distance between the left side and the right side of the aluminum foil cut 13 is 40 - 50 mm, preferably 46 mm, denoted as L. By reasonably designing the distance range between the left side and the right side of the aluminum foil cut 13, while reducing costs, it can also ensure that the heating film of this toilet seat can achieve uniform heating of the seat surface, eliminating the phenomenon of local overheating or overcooling, effectively solving the problem of local overheating or overcooling in traditional heating films, and improving the user's comfort.

[0031] In order to stably install the heating film of this toilet seat, a number of positioning and installation holes 14 are provided on the aluminum foil film 1. The heating film of this toilet seat is matched and installed in the shell of the toilet seat, and positioning and fixing are carried out by using structures such as positioning posts or bolts passing through the positioning and installation holes 14, strengthening the installation stability of the heating film of this toilet seat.

[0032] In this embodiment, the heating film of this toilet seat further includes a heat-insulating wire 3, a temperature control switch 4 and a crimping terminal 5; there are two heat-insulating wires 3; one end of one heat-insulating wire 3 is connected to the electrical input end of the temperature control switch 4, between the electrical output end of the temperature control switch 4 and the electrical input end of the heating wire 2, and between the electrical output end of the heating wire 2 and one end of the other heat-insulating wire 3 are all connected through the crimping terminal 5; the temperature control switch 4 and the crimping terminal 5 are both arranged between the two aluminum foil films 1. By designing the connection between the temperature control switch 4, the heat-insulating wire 3, the crimping terminal 5 and the heating wire 2 to achieve electrical connection, the structural connection is simple, stable and reliable, and the temperature control switch 4 can play a good temperature control role, being able to automatically disconnect the circuit, thereby preventing fires or equipment damage that may be caused by overheating.

[0033] In order to better insulate the temperature control switch 4 and the crimp terminal 5, so as to facilitate the installation of such a structure between two aluminum foil films 1 and play a good protective role, PVC sleeves 6 are sleeved on the outer surfaces of the temperature control switch 4 and the crimp terminal 5. The PVC sleeve 6 has heat resistance, plays a good heat insulation and protection for the temperature control switch 4 and the crimp terminal 5, and prevents the structure from being damaged due to excessive temperature.

[0034] It should be noted that the heat-insulated wire 3, the temperature control switch 4 and the crimp terminal 5 are all common standard parts or components known to those skilled in the art, and their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods.

[0035] In summary, the embodiment of the present utility model provides a heating film for a toilet seat ring. Among them, according to the internal shape of the housing of the toilet seat ring, the heating film of the toilet seat ring is set. On the basis of the aluminum foil film 1, the heating wire 2 and the hot melt adhesive, the heating wire 2 is improved. By setting the edge heating section 21, the left coiled heating section 22, the right coiled heating section 23 and the rear coiled heating section 24 to form the heating wire 2, first the edge heating section 21 is arranged along the inner ring edge 11 to form a basic heating band similar to a ring, effectively avoiding the cold feeling at the edge of the seat ring; then the left coiled heating section 22, the right coiled heating section 23 and the rear coiled heating section 24 are coiled and arranged relative to the left side, right side and rear side of the aluminum foil film 1 between the edge heating section 21 and the outer ring edge 12. Through this unique layout design of the heating wire 2, not only the heating area is increased, but also the heat is evenly distributed in a coiled manner, thereby realizing the uniform heating of the seat ring surface, eliminating the phenomenon of local overheating or overcooling, effectively solving the problem of local overheating or overcooling in the traditional heating film, improving the user's comfort, and at the same time, the uniform heating reduces unnecessary energy consumption waste, making the entire heating process more energy-efficient.

[0036] The above are only the preferred embodiments of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present application, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present application.
