Description

Seat ring and manufacturing method thereof

Technical Field

The invention relates to a sanitary ware, in particular to a seat ring and a manufacturing method thereof.

Background

With the rapid development of science and technology, people's life becomes more and more convenient, and the intelligent level of bathroom products is also improving constantly. The intelligent bathroom refers to the application of modern technologies such as electric control and automation to bathroom products, so that the functionality of the bathroom products is enhanced, and the health comfort and the convenience of bathroom experience are improved.

The squatting pan is the indispensable intelligent bathroom product of family, and the squatting pan passes through seat circle and human contact, because the seat circle adopts plastics PP material, has the sense of touch of ice cunning, for avoiding the user to feel the ice-cold stimulation on the seat circle, current squatting pan has functions such as seat circle heating, and is more humanized in the design. The prior seat ring structure with heating function comprises: the cavity is arranged in the seat ring or at the bottom (back to one side of the human body), the high-power electric heating layer is arranged in the cavity, for example, the high-power heating layer is arranged between rear decorative shells made of surface layer materials and magnesium alloy materials, and the heating layer is surrounded and limited by the seat ring. However, when the heating layer releases heat, the heat needs to first pass through the skin material of the race, with some time delay and loss of heat energy. Particularly, in cold environments, the heating layer needs to maintain a certain standby power in order to maintain the seat ring in a rapid heating state. Meanwhile, in order to heat the seat ring rapidly in use, the heating layer is required to maintain high-power operation, which increases the difficulty for the selection and production of the heating layer. For example, the existing intelligent toilet bowl mostly pursues the fast heating effect, namely, the toilet bowl senses that a human body is close to the toilet bowl, the toilet bowl is automatically heated, and after 6-7 seconds, a user can feel heat immediately when sitting on the toilet bowl. If the temperature of the heating layer is too high or too low, the normal use of the seat ring is influenced, and the comfort is influenced. Generally, the heating power of the seat needs to be 600-800W, and the power supply of the toilet cannot be turned off even when the toilet does not work at ordinary times, so that a certain standby power must be ensured, and thus, a quick heating effect can be realized when a user uses the toilet, and the energy consumption and the use cost of the toilet are increased. In order to save energy, the energy consumption is kept standby and low when the toilet is not used, meanwhile, the quick heating is realized when the toilet is used, whether the toilet is about to be used or not is sensed in advance through complicated software calculation or related hardware design is added, although the induction of the amount of advance time is increased, the energy consumption can be relatively reduced when a user is induced to prepare to use the toilet, and the production cost is increased.

The temperature sensor 3 can be embedded before or after the flexible heating film 2 enters the first mold, for example, after the temperature sensor 3 is placed in the first mold, the temperature sensor 3 is connected with the flexible heating film 2 and is directly injected into the seat ring body 1.

Preferably, before the step (3), the method further comprises: set up the first recess 11 that is used for holding temperature sensor 3 on seat circle body 1 towards flexible heating film 2 one side surface, be connected with flexible heating film 2 when temperature sensor 3, temperature sensor 3 arranges in first recess 11. With the above assembly method, the temperature sensor 3 is placed in the first groove 11, for example, the seat ring body 1 is embedded during the injection molding process, and the temperature sensor 3 is connected with the flexible heating film 2. The first groove 11 provides a space for accommodating the temperature sensor 3, so that the comfort of the seat ring body 1 is prevented from being affected by local protrusions.

In addition, it is preferable that before the step (3), further comprising: a through hole is formed in the seat ring body 1, a temperature sensor 3 is installed at one end, close to the flexible heating film 2, of the through hole, and a sealing layer is arranged at one end, far away from the flexible heating film 2, of the through hole. By adopting the assembly mode, the temperature sensor 3 is arranged in the through hole, the temperature sensor 3 is kept connected with the flexible heating film 2, and then the sealant is filled to form the sealing layer. The through hole provides a containing space for the temperature sensor 3, so that the comfort of the seat ring body 1 is prevented from being influenced by local bulges; meanwhile, the through hole is used as a through hole, so that the manufacturing difficulty is reduced, and the sealing layer can provide protection and sealing effects for the temperature sensor 3.

The process of making the seat ring is further described below.

(1) Bending the heating wire according to the surface shape of the seat ring body 1 to form a heating layer 21, pre-fixing the heating layer 21 on a heat conduction insulating layer 22, and removing redundant conductive materials of the heating layer 21 by adopting an etching or carving process;

(2) coating an adhesive layer 23 on the heating layer 21, then putting the film layers into a second mold, heating the second mold to a second preset temperature/pressurizing to a preset pressure, keeping for a second preset time to form a flexible heating film 2 with a certain shape, and standing and cooling;

(3) placing the flexible heating film 2 in a first mold for manufacturing the seat ring body 1;

(4) filling a medium into the first mold, heating the first mold to a first preset temperature, keeping for a first preset time, and standing and cooling to enable the flexible heating film 2 to cover the surface of the toilet seat body 1, which is back to the toilet seat;

(5) the temperature sensor 3 is connected with the flexible heating film 2 and/or the seat ring body 1 so as to timely control the starting, stopping or lifting power of the flexible heating film 2.

From the above description and practice, it can be seen that the seat ring and the method of making the same provided by the present invention have the following advantages over the prior art: by adopting the seat ring, the flexible heating film is arranged on the surface of the seat ring body, and the heat released by the flexible heating film can be directly transferred to a user; the heat released by the flexible heating film can be kept in a proper range; the seat ring body realizes the effects of fast heat conduction and small energy loss, so that the seat ring has an instant heating function, and the temperature of the seat ring is kept in a proper temperature range.

Those of ordinary skill in the art will understand that: the above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents, improvements and the like made within the spirit of the present invention should be included in the scope of the present invention.
