Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bathrooms, in particular to an anti-siphon water inlet valve for a toilet. Background Art
[0002] The water inlet valve of the toilet tank is directly connected to the tap water pipe. When the tap water pipe is cut off or in a low water pressure state, the water inlet valve connected to it will generate negative pressure, causing the water in the toilet tank to flow back into the tap water pipe based on the siphon principle, thereby contaminating the clean water in the tap water pipe. For this reason, the water inlet valve is currently required to have an anti-siphon function.
[0003] A highly reliable anti-siphon water inlet valve is proposed in the patent with publication number CN204608920U. In this patent, once a situation such as water outage occurs, the anti-siphon pad will cover the main outlet of the diversion channel under the action of negative pressure, so that the water in the water tank is not easy to flow back into the water inlet pipe. When the water supply is restored, an auxiliary communication channel is provided between the diversion channel and the water outlet pipe. This auxiliary communication channel is used to balance the pressure on both sides of the anti-siphon pad to a certain extent, so that low-pressure water can also easily flush the anti-siphon pad, thereby ensuring that the water inlet is smoother when the water pressure is low. However, there are still the following problems in this patent:
[0004] The above-mentioned anti-siphon water inlet valve may cause the water inlet pipe to be blocked after long-term use, and it needs to be dismantled and the filter needs to be cleaned.

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings, and several embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0024] like Figure 1-3 As shown, an anti-siphon water inlet valve for a toilet includes a valve body 1, and a convenient removal component 5 is provided at the lower end of the valve body 1;
[0025] The easy-to-remove component 5 includes a reinforcement sleeve 501 arranged on the outer wall of the lower end of the valve body 1, and a water inlet sleeve 502 is arranged near the lower end of the inner wall of the reinforcement sleeve 501. Two sets of slide grooves 506 are opened on the inner wall of the water inlet sleeve 502. An anti-skid pad 507 is arranged on one side of the lower end of the slide groove 506, and a spring 508 is arranged on one side of the anti-skid pad 507. An inclined block 509 is arranged at one end of the spring 508. A protruding block 504 is embedded in the inner wall of the slide groove 506, and a filter screen 503 is connected to one side of the protruding block 504, and a hand-held rod 505 is connected to the bottom of the filter screen 503.
[0026] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the reinforcement sleeve 501 is detachably connected to the valve body 1, the water inlet sleeve 502 is detachably connected to the reinforcement sleeve 501, the hand-held rod 505 is non-detachably connected to the filter screen 503, the protruding block 504 is non-detachably connected to the filter screen 503, the filter screen 503 is slidably engaged with the slide groove 506, the anti-skid pad 507 is non-detachably connected to the slide groove 506, the spring 508 is non-detachably connected to the anti-skid pad 507, and the spring 508 is non-detachably connected to the tilting block 509;
[0027] The hand-held rod 505 is non-detachably connected to the filter 503, so the filter 503 can be taken out by holding the hand-held rod 505. The protruding block 504 is slidably engaged with the slide groove 506, so that it can be stuck after sliding into the slide groove 506 and will not slide out.
[0028] The working process of the utility model is as follows: when the anti-siphon water inlet valve of the toilet seat designed by the present invention is used, water enters through the water inlet sleeve 502 and is filtered through the filter screen 503 before entering the valve body 1. By operating the valve body 1, the toilet seat can be flushed. When the valve body 1 is blocked after long-term use, the valve body 1 is taken out, and the protruding block 504 on the outer wall of the filter screen 503 is pulled down by sliding with the inner wall of the slide groove 506 by manually pulling the hand-held rod 505, and the inclined block 509 at the lower end of the slide groove 506 is squeezed by one end of the protruding block 504 on the outer wall of both sides of the filter screen 503, so that it is subjected to force by the spring 508 to shrink, thereby shrinking the inclined block 509 into The inner wall of the slide groove 506 can move the protruding block 504 out along the inclination of the inclined block 509, which is convenient for taking out the filter screen 503 and subsequently cleaning the filter screen 503. After cleaning, the protruding block 504 on the outer wall at one end thereof is squeezed against the inclined block 509 to shrink the inclined block 509 into the slide groove 506, thereby allowing the protruding block 504 to enter the inner wall at the lower end of the slide groove 506 along the inclination of the inclined block 509. When the filter screen 503 completely enters the water inlet sleeve 502, the spring 508 rebounds to eject the inclined block 509 and pull it to the top side of the filter screen 503 to complete the installation. The operation is simple and does not require the aid of tools, making it more convenient for people to operate and use.
[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
