[0045] As Figures 1 to 13 shown, the present application provides an automatic anti-blocking signal module with quick assembly and disassembly, which comprises a lower shell 1 and an upper shell 2. The upper shell 2 is located above the lower shell 1 and is connected with the lower shell 1 through clamping, so as to facilitate the quick assembly of the lower shell 1 and the upper shell 2. Meanwhile, a water discharge channel 21 is formed at the connection between the upper shell 2 and the lower shell 1, so that the water flow is discharged through the main waterway drainage channel 22 at the sidewall of the upper shell 2. A signal emitting device 3 is installed at the top of the upper shell 2, which is used for emitting and transmitting a predetermined switch signal. A containing cavity is formed between the upper shell 2 and the lower shell 1, and a diaphragm support 4, a protective shell 5, a sealing diaphragm 6, a reset spring member 7 and a signal inducing device 8 are installed in the containing cavity.

[0046] The protection shell 5 is long columnar, and a long strip through hole 50 is formed in the middle of the protection shell 5 as a main water inlet channel 9; the specific shape of the long strip through hole 50 is designed by referring to the Venturi principle by those skilled in the art, and is not specifically limited in the application. The diaphragm support 4 is sleeved at the bottom of the protection shell 5 and is buckle-connected with the protection shell 5 to form a diaphragm group, the buckle connection is convenient to assemble, and the sealing diaphragm 6 and the signal inducing device 8 are installed in the cavity of the diaphragm group, the diaphragm support 4, the protection shell 5, the sealing diaphragm 6 and the signal inducing device 8 are assembled into an integral whole and move together with the displacement of the sealing diaphragm 6. Specifically, a limiting clamping groove 20 is formed at the bottom of the upper shell 2, and a corresponding notch position 11 is formed on the outer wall surface of the top of the lower shell 1, and the second end 61 of the sealing diaphragm 6 is clamped at the limiting clamping groove 20 and the notch position 11 to limit and fix the second end 61 of the sealing diaphragm 6.

[0047] The reset spring member 7 includes a spring body 70 and a anti-blocking rod 71 arranged in the spring body 70, one end of the spring body 70 is connected with the upper shell 2, and the other end is connected with the sealing diaphragm 6 for resetting the sealing diaphragm 6, and the anti-blocking rod 71 is arranged in the long strip through hole 50 in the middle of the protection shell 5, under the driving of the reset spring member 7, the diaphragm support 4, the protection shell 5, the sealing diaphragm 6 and the signal inducing device 8 move up and down together with the diaphragm support 4, so that the anti-blocking rod 71 disperses the dirt around the long strip through hole 50, and the effect of automatic anti-blocking is achieved.

[0048] The working principle of the automatic anti-blocking signal module with quick assembly and disassembly in the application is as follows:

[0049] 1) cavities are respectively formed on the upper and lower surfaces of the sealing diaphragm 6, and are divided into a first cavity arranged below the sealing diaphragm 6 and a second cavity arranged above the sealing diaphragm 6, the first cavity is communicated with the main water outlet channel 22 through a water discharge channel 21, and the first cavity is communicated with the second cavity through the long strip through hole 50 of the protection shell 5.

[0050] 2) after the main water inlet channel starts to pass water, the water flow rapidly fills the first cavity below the sealing diaphragm 6, at this time, the sealing diaphragm 6 and the lower shell 1 are still in a sealed state, and the main water outlet channel 22 is still in a closed state, so the water flow can only flow into the second cavity above the sealing diaphragm 6 through the long strip through hole 50, as shown in the state one screenshot, and the state one is that the sealing diaphragm 6 is not moved up, and the reset spring member 7 is in a reset state. Figure 2 、 3

[0051] ​After water flows through the main water channel, the water pressure in the first cavity below the sealing diaphragm 6 generates a force F1 (F1 is the product of P1 and S1); the water pressure in the second cavity above the sealing diaphragm 6 generates a force F2 (F2 is the product of P2 and S2); the total force above the sealing diaphragm 6 is the sum of F2 and F3.

[0052] Among them, P1 is the water pressure below the sealing diaphragm;

[0053] S1 is the water contact area below the sealing diaphragm;

[0054] F1 is the water pressure force above the sealing diaphragm 6;

[0055] P2 is the water pressure above the sealing diaphragm;

[0056] S2 is the water contact area above the sealing diaphragm;

[0057] F2 is the water pressure force below the sealing diaphragm 6;

[0058] F3 is the force of the return spring 7.

[0059] 3) Based on the principle of pressure decay when fluid passes through an elongated hole, a pressure difference is generated on both sides of the water after it flows out through the elongated through hole 50. Therefore, when the water in the first cavity flows from the elongated through hole 50 to the second cavity, a pressure difference will occur between the two cavities. At the same time, in the initial state, the pressure F1 of the first cavity (below the sealing diaphragm 6) is set to be greater than the pressure F2+F3 of the second cavity (above the sealing diaphragm 6). The pressure difference generated at this time pushes the diaphragm group to move upward.

[0060] When the diaphragm group moves upwards for a certain distance, the main waterway drainage channel 22 starts to drain. During the upward displacement of the diaphragm group, the signal inducing device 8 is driven into the working area of ​​the signal transmitting device 3. The signal transmitting device 3 works, sends a signal, and induces the signal inducing device 8 to operate. When the pressure of the two chambers reaches equilibrium (F1 = F2 + F3), the diaphragm group will no longer move upwards, as shown in the figure. Figure 4 、 5 As shown in the screenshot of state 2, state 2 is when the sealing diaphragm 6 moves upward and the return spring 7 is in a compressed state.

[0061] 4) When the main water inlet channel is closed and water is flowing, the two forces F1 and F2 generated by the water pressure will disappear, and the force F3 generated by the reset spring 7 will push the diaphragm group downward until it returns to its original position. At this time, the signal inducing device 8 leaves the working area of ​​the signal transmitting device 3, and the signal transmitting device 3 no longer works and does not send any signals.

[0062] The automatic anti-blocking signal module with quick assembly and disassembly in the application is designed as buckle connection between the upper shell 2 and the lower shell 1 and between the protective shell 5 and the diaphragm support 4, facilitating the assembly of the product, so that the product has the functions of quick assembly and disassembly; and the diaphragm skeleton in the prior art is replaced by the design of the protective shell 5 and the diaphragm support 4, so that the product disassembly operation is more convenient and easy to manufacture. At the same time, the sealing diaphragm 6 and the signal inducing device 8 are installed in the cavity of the diaphragm group, and the signal emitting device 3 is installed at the top of the upper shell 2, which is always not in contact with water, avoiding problems such as unstable operation and signal transmission affected caused by contact with water. In addition, by using the principle of pressure difference of water on both sides of the slender hole, the water flow is set to flow preferentially from the long strip through hole 50 of the protective shell 5, and under the driving of the reset spring member 7, the diaphragm support 4, the protective shell 5, the sealing diaphragm 6 and the signal inducing device 8 move up and down with the diaphragm support 4, so that the anti-blocking rod 71 scatters the dirt around the long strip through hole 50, achieving the effect of automatic anti-blocking.

[0063] Further, a first clamping groove 51 is formed at the bottom of the protective shell 5 along the circumferential direction thereof.

[0064] A through hole 40 is arranged in the middle of the diaphragm support 4, and a first protrusion 41 matched with the first clamping groove 51 is formed at the bottom of the through hole 40, the first protrusion 41 is installed in the first clamping groove 51, so as to realize the buckle connection between the protective shell 5 and the diaphragm support 4, and the implementation is simple and reliable.

[0065] Similarly, a plurality of second clamping grooves 23 are formed at the bottom of the upper shell 2 along the circumferential direction thereof.

[0066] A second protrusion 10 matched with the second clamping groove 23 is formed on the outer wall surface of the lower shell 1, the second protrusion 10 is arranged in the second clamping groove 23, so as to realize the buckle connection between the upper shell 2 and the lower shell 2, and the implementation is simple and reliable.

[0067] Further, the protective shell 5 includes a circular truncated cone part 52 and a columnar part 53, the circular truncated cone part 52 is hollow annular, and the bottom of the circular truncated cone part 52 is inwardly recessed to form a first cavity 521 for accommodating the signal inducing device 8. Correspondingly, the first end 60 of the sealing diaphragm 6 is inserted into the first cavity 521 at the bottom of the circular truncated cone part 52 and abuts against the lower surface of the signal inducing device 8, and the signal inducing device 8 is always in a sealed state with the protective shell 5 and the sealing diaphragm 6 during the whole movement process and is not in contact with water, so as to realize the sealing of the signal inducing device 8 and avoid problems such as unstable operation and signal transmission affected caused by contact with water. Specifically, a plurality of third protrusions 522 are arranged at the inner wall surface of the first cavity 521 of the circular truncated cone part 52 along the circumferential direction thereof, so as to realize the positioning installation of the signal inducing device 8, which is beneficial to the installation of the signal inducing device 8.

[0068] Specifically, the bottom of the columnar portion 53 is provided with a first opening 531, so that the columnar portion 53 is divided into two parts, i.e. a left columnar portion and a right columnar portion. The first opening 531 increases the elasticity of the bottom of the columnar portion 53, which is beneficial to the snap installation between the protective shell 5 and the diaphragm support 4.

[0069] Further, the bottom end of the sealing diaphragm 6 is provided with a second opening 62, so that the outer wall of the bottom end of the sealing diaphragm 6 is inclined outward to form a sealing slope 63, which enhances the sealing performance when the sealing diaphragm 6 slides. Correspondingly, the inner wall of the lower shell 1 is provided with a plurality of guide sliding blocks 12 along the circumferential direction. The guide sliding blocks 12 prevent the sealing slope 63 from being turned up during the up-and-down movement of the sealing diaphragm 6.

[0070] Specifically, the guide sliding block 12 is in a strip shape, so that there is a sealing position between the sealing diaphragm 6 and the bottom end of the lower shell 1, which ensures that the signal module can work normally under low water pressure and ensures the stable operation of the product. The top end of the guide sliding block 12 is a bevel surface 121, which facilitates the insertion and installation of the sealing diaphragm 6.
