Description

Technical Field

[0001] The present invention relates to the technical field of toilets, and in particular to a toilet spray gun self-cleaning system and method. Background Art

[0002] At present, the use of toilets has become very popular, and the types and functions of toilets (such as: equipped with a spray gun to wash the user's buttocks after defecation) are becoming more and more diverse. However, in the process of cleaning the user, the surface of most toilets equipped with a spray gun will inevitably be contaminated by excrement. Even if the surface of the spray gun is cleaned with water, only the excrement visible to the naked eye can be washed away, and some bacteria carried in the excrement will still adhere to the surface of the spray gun, and the bacteria will breed and multiply on the surface of the spray gun; once the spray gun is contaminated, it will pose a threat to the user's health.

[0003] At present, most smart toilet manufacturers in the industry use ultraviolet sterilization technology or electrolyzed water sterilization technology to sterilize the surface of the spray gun. However, the above two sterilization technologies also have their own obvious disadvantages:

[0004] 1. The area that can be treated by ultraviolet sterilization is very small, and it is impossible to completely cover the surface of the spray gun. There are sterilization dead corners. In addition, to achieve a good sterilization effect, ultraviolet rays need to act for a long time (more than several minutes), and the applicability is poor;

[0005] 2. Electrolyzed water sterilization is heavily dependent on the chloride ion concentration in tap water (if the chloride ion concentration is low, it cannot produce enough hypochlorous acid for sterilization). However, the chloride ion concentration in tap water varies greatly in different regions. Therefore, the sterilization effect of this sterilization technology is not reliable and cannot be widely promoted and used.

[0006] With regard to the problem that the sterilization effect of the surface of the toilet spray gun in the related art is not good, no effective solution has been given so far.

[0007] Therefore, the inventor, relying on many years of experience and practice in related industries, proposes a toilet spray gun self-cleaning system and method to overcome the defects of the prior art. Summary of the invention

[0008] The purpose of the present invention is to provide a toilet spray gun self-cleaning system and method, which can quickly and fully sterilize the entire spray gun, and is safe and reliable, greatly improving the user experience and having good applicability.

[0045] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0046] Implementation Method 1

[0047] like Figures 1 to 7 As shown, the present invention provides a toilet spray gun self-cleaning system, which includes a toilet body 1, a top cover 2, a spray gun 3 and a steam generator 4, wherein the top cover 2 is hinged to the top of the toilet body 1, a drain port 101 is provided inside the toilet body 1, and the spray gun 3 is provided above the drain port 101; a steam outlet 803 is provided at a position connected between the spray gun 3 and the toilet body 1. During use of the present invention, after the spray gun 3 has finished cleaning the user, high-temperature steam can be introduced into the spray gun 3 through the steam generator 4, thereby heating the spray gun 3 as a whole at high temperature, so as to achieve the purpose of rapid and sufficient sterilization of the spray gun 3, without a sterilization blind spot, and with a better sterilization effect.

[0048] Specifically, Figure 6 As shown, the spray gun 3 is provided with a steam inlet 802 and a steam outlet 803 , and the spray gun 3 is connected to the steam generating device 4 via the steam inlet 802 .

[0049] In an optional embodiment of the present invention, Figure 4 As shown, a cavity 9 for accommodating the spray gun 3 is provided on the toilet body 1, and a steam outlet 803 is provided on the toilet body 1 and connected to the cavity 9. Preferably, in this embodiment, before the spray gun 3 performs steam sterilization, the top cover 2 is closed so that the spray gun 3 is in a closed space, and the steam enters the cavity 9 through the steam inlet 802, and the high-temperature steam sterilizes the outer surface of the spray gun 3.

[0050] In an optional embodiment of the present invention, Figure 3 As shown, a cooling component 6 for cooling the spray gun 3 is provided outside or inside the spray gun 3. After the spray gun 3 is sterilized, the cooling component 6 can be used to cool the spray gun 3, which can effectively prevent the spray gun 3 from being overheated and scalding the user, improve the safety of the toilet, enhance the user's experience, and has good applicability.

[0051] In an optional embodiment of the present invention, Figure 5 , Figure 6 As shown, the spray gun 3 includes a spray gun housing 302 , an integrated water component 8 is disposed inside the spray gun housing 302 , and a steam flow channel 801 is formed inside the spray gun 3 .

[0052] Further, such as Figure 6 As shown, the steam flow channel 801 includes a third steam flow channel 301, which is formed between the spray gun housing 302 and the integrated water component 8, and the steam inlet 802 and the steam outlet 803 are respectively located on the integrated water component 8, and the steam inlet 802 and the steam outlet 803 are respectively connected to the steam flow channel 801.

[0053] Further, such as Figure 6 As shown, the steam flow channel 801 also includes a first steam flow channel 8011 and a second steam flow channel 8012. The first steam flow channel 8011 and the second steam flow channel 8012 are both linear cavities extending along the axial direction of the spray gun 3. One end of the first steam flow channel 8011 and one end of the second steam flow channel 8012 are respectively connected to the steam pipeline, the other end of the first steam flow channel 8011 is connected to the steam inlet 802, and the other end of the second steam flow channel 8012 is connected to the steam outlet 803. The first steam flow channel 8011 and the second steam flow channel 8012 cooperate to allow the high-temperature steam to fully heat the entire spray gun 3, thereby ensuring a good sterilization effect.

[0054] Further, such as Figure 6 As described above, the first steam flow channel 8011 and the second steam flow channel 8012 both penetrate the integrated water component 8 to ensure a good heating and sterilization effect.

[0055] Further, such as Figure 6 As shown, the third steam flow channel 301 is an annular cavity located outside the first steam flow channel 8011 and the second steam flow channel 8012 and arranged along the circumference of the spray gun 3. One end of the third steam flow channel 301 is connected to the first steam flow channel 8011 through the steam inlet 802, and the other end of the third steam flow channel 301 is connected to the second steam flow channel 8012 through the steam outlet 803. The heating efficiency of the spray gun 3 is further improved through the third steam flow channel 301, ensuring a good sterilization effect.

[0056] In an optional embodiment of the present invention, Figure 2 , Figure 5 , Figure 6 As shown, a water tank 5 is provided on the toilet body 1, and a water inlet pipe 7 is provided on the spray gun 3, one end of the water inlet pipe 7 is connected to the spray gun 3, and the other end of the water inlet pipe 7 is connected to the water tank 5. The water tank 5 can be used as a water source to supply the spray gun 3, and of course other water sources can be selected to supply water to the spray gun 3. In addition, the cooling component 6 can use the tap water in the self-opening water pipe as the water source, and can also use the water in the water tank 5 as the water source.

[0057] Further, the cooling component 6 may be, but is not limited to, a water spray pipe, one end of the cooling component 6 extends into the interior of the spray gun 3 and is connected to the steam flow channel 801 or is located outside the spray gun 3, and the other end of the cooling component 6 is connected to the water tank 5. When the cooling component 6 extends into the spray gun 3 to spray water, the water flow may flow through the steam flow channel 801, thereby cooling the spray gun 3 from the inside to the outside; when the cooling component 6 is located outside the spray gun 3, the cooling component 6 sprays water on the outer surface of the spray gun 3, thereby cooling the spray gun 3 from the outside to the inside.

[0058] Furthermore, the spray gun 3 can be connected to the toilet body 1 through but not limited to a telescopic rod or a slide rail to ensure that the spray gun 3 can be telescopically moved without affecting the user's normal use of the toilet.

[0059] Furthermore, a safety lock is provided between the toilet body 1 and the top cover 2. After use, the top cover 2 and the toilet body 1 can be self-locked, thereby preventing the user from using the toilet when the spray gun 3 is performing disinfection, thereby avoiding burns to the user.

[0060] In an optional embodiment of the present invention, Figure 2As shown, the steam generating device 4 can be but is not limited to a steam generator, and the steam generating device 4 is arranged on the toilet body 1, and the steam outlet 803 of the steam flow channel 801 is connected to the water tank 5 or the drain 101 of the toilet. The high-temperature steam is generated by the steam generating device 4 and transported to the steam flow channel 801. After the spray gun 3 is sterilized, the steam condensed water in the steam flow channel 801 can be discharged to the water tank 5 or the drain 101 of the toilet through the steam outlet 803.

[0061] Since high-temperature steam is a heat source with a high enthalpy value, it can quickly heat the surface of an object, causing the temperature of the surface of the object to rise rapidly. The high temperature can destroy the protein of bacteria, thereby playing an effective sterilization role. The generation of high-temperature steam has no special requirements on water quality. In the present invention, tap water or water stored in the water tank 5 of the toilet can be used as a water source for generating high-temperature steam, which is convenient for ordinary users.

[0062] The characteristics and advantages of the toilet spray gun self-cleaning system of the present invention are:

[0063] 1. The toilet spray gun self-cleaning system can heat the surface of the spray gun 3 to above 100°C through high-temperature steam, which can fully and thoroughly sterilize with good sterilization effect, thereby achieving the purpose of efficient sterilization.

[0064] 2. In the process of sterilizing the spray gun 3 of the toilet spray gun self-cleaning system, high-temperature steam flows in the steam flow channel 801 throughout the whole process, and the heat utilization rate is high.

[0065] 3. In the toilet spray gun self-cleaning system, the steam generating device 4 has a relatively high power and can quickly generate high-temperature steam, so the outer surface of the spray gun 3 can be quickly sterilized.

[0066] Fourth, during the sterilization process of the spray gun 3 of the toilet spray gun self-cleaning system, the top cover 2 of the toilet is in a self-locking state, and the user cannot come into contact with the spray gun 3 and high-temperature steam, which has higher safety.

[0067] Implementation Method 2

[0068] like Figures 1 to 7 As shown, the present invention provides a toilet spray gun self-cleaning method, which is used in conjunction with the above-mentioned toilet spray gun self-cleaning system, and includes the following steps:

[0069] Step S1: After the spray gun 3 finishes cleaning the user, the top cover 2 of the toilet is closed and self-locked with the toilet body 1, and the steam generating device 4 generates high-temperature steam and passes it into the steam flow channel 801 of the spray gun 3. The high-temperature steam flows through the steam flow channel 801, thereby heating the spray gun 3 as a whole;

[0070] Step S2: After the high-temperature steam continues to heat the spray gun 3 for a preset time, the steam generating device 4 stops working, and then stops passing the high-temperature steam into the steam flow channel 801, completing the self-cleaning process of the spray gun 3;

[0071] In an optional embodiment of the present invention, after step S2, the method further includes:

[0072] Step S3: the spray gun 3 is extended to the top of the drain port 101 of the toilet, and the cooling component 6 cools the steam channel 801 or the outer surface of the spray gun 3 by spraying water;

[0073] Step S4: After the water flow continues to cool the spray gun 3 for a preset time, the spraying of the water flow is stopped and the spray gun 3 retracts to its original position;

[0074] Step S5: the top cover 2 of the toilet is unlocked, and the self-cleaning process of the spray gun 3 is completed.

[0075] The characteristics and advantages of the toilet spray gun self-cleaning method of the present invention are:

[0076] The self-cleaning method for the toilet spray gun can sterilize the spray gun 3 quickly and fully without any sterilization blind spots, and has a better sterilization effect. The sterilized spray gun 3 can also be cooled to effectively prevent the spray gun 3 from being overheated and scalding the user, thereby improving the safety of the toilet and enhancing the user's experience. The method has good applicability and is suitable for large-scale promotion and use.

[0077] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention.
