Active triggering piece

Abstract

The utility model relates to the technical field of trigger switches, and discloses an active trigger piece which comprises a supporting piece and a water passing piece installed in the supporting piece, the water passing piece comprises a flexible pipe which freely expands and contracts along with water pressure, and an elastic trigger piece is further arranged along the outer side of the flexible pipe. Limiting holes are further formed in the inner side of the supporting piece and the elastic triggering piece, and the elastic triggering piece slides along the limiting holes. When the flexible pipe has water pressure, the elastic triggering piece is expanded by the flexible pipe to move outwards, and when the flexible pipe does not have water pressure, the elastic triggering piece elastically resets to extrude the flexible pipe to contract inwards. By arranging the flexible pipe and the elastic trigger piece matched with the flexible pipe, when water pressure exists in the pipe, the end of the elastic trigger piece triggers the switch button, so that the unit controlled by the switch is started, and when no water pressure exists in the pipe, the elastic trigger piece resets under the action of elastic force, so that the unit controlled by the switch is closed.

Description

Technical Field

[0001] This utility model relates to the field of trigger switch technology, specifically to an active triggering element. Background Technology

[0002] Control switches can be installed in the water path through which the fluid flows to perform functions such as sterilization or heating. However, existing traditional water flow triggering devices rely on electronic sensors, which have problems such as complex structure, high cost, and susceptibility to water environment interference (such as circuit failure caused by humidity). To address this, we propose a mechanical switch that is actively triggered by water flow. It can be automatically triggered when water flows through and automatically disconnected when no water flows through. Utility Model Content

[0003] The purpose of this invention is to provide an active triggering element to solve the above-mentioned technical problems.

[0004] This utility model provides the following technical solution:

[0005] An active triggering element includes: a support member, a water-conducting element installed in the support member, the water-conducting element including a flexible tube that expands and contracts freely with water pressure, an elastic triggering element being provided along the outer side of the flexible tube, and a limiting hole being provided between the inner side of the support member and the elastic triggering element, the elastic triggering element sliding along the limiting hole;

[0006] When the flexible tube is under water pressure, the elastic trigger moves outward as the flexible tube expands; when there is no water pressure, the elastic trigger elastically resets and compresses the flexible tube inward to contract.

[0007] The water-passing component also includes an end cap integrally formed with the flexible pipe;

[0008] The active trigger includes a seal for sealing the end cap and the contact surface of the support member.

[0009] Furthermore, the elastic trigger consists of a movable member and a spring, with the spring positioned between the movable member and the limiting hole. The tail of the limiting hole also has a limiting point that restricts the tail of the spring.

[0010] Furthermore, the elastic trigger is a movable spring.

[0011] Furthermore, the movable spring is L-shaped and is located on the outside of the flexible tube. One end of the movable spring is fixed inside the support member, and the other end of the movable spring extends into the limiting hole.

[0012] Furthermore, the movable spring is a stainless steel sheet.

[0013] Furthermore, the sealing element is a fixing element that is pressed onto the upper and lower ends of the end cap, and a pressure block for pressing the end cap is also formed on the inner side of the fixing element.

[0014] Furthermore, the fastener also has a buckle, and the inner side of the support also has a snap-fit ​​point, into which the buckle is embedded during installation.

[0015] Furthermore, the pressure block and the water passage hole of the flexible tube are also provided with through holes of the same size.

[0016] Furthermore, the sealing element is a sealant disposed in the gap between the end cap and the support member.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this invention, a flexible tube is provided, and an elastic triggering element adapted to the flexible tube triggers a switch button at its end when there is water pressure inside the tube, causing the unit controlled by the switch to start. When there is no water pressure inside the tube, the elastic triggering element resets under the action of elastic force, causing the unit controlled by the switch to close.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] like Figure 1-3 As shown, this utility model provides a technical solution: an active triggering component, including a support component 100, a water-passing component 300 for water passage, and a sealing component for pressing the contact end faces of the water-passing component 300 and the support component 100.

[0029] The water-passing component 300 includes an end cap 310 and a flexible pipe 320 that can freely change shape with water flow. In the non-water-passing state, there is a certain amount of variable allowance between the flexible pipe 320 and the inner wall of the support component 100, such as... Figure 3 As shown, a movable member 140 is also provided on the outer side of the flexible tube 320. A limiting hole 150 is also provided on the inner side of the support member 100 corresponding to the movable member 140. The movable member 140 can move along the limiting hole 150. When water flows through the flexible tube 320, the flexible tube 320 is expanded by the water pressure towards the inner wall of the support member 100. At this time, the flexible tube 320 squeezes the movable member 140, causing the movable member 140 to move outward along the limiting hole 150. A switch can be provided on the outer side of the movable member 140. The switch can be such as an elastic switch. The movement of the movable member 140 triggers the switch button. When the water pressure is maintained, the switch button is continuously squeezed to realize the switch passage. This switch can be used to trigger the lighting of a germicidal lamp, etc.

[0030] A spring 130 is provided between the movable part 140 and the limiting hole 150. A limiting point 160 is also provided at the tail end of the limiting hole 150. The limiting point 160 is used to abut the tail of the spring 130 to prevent the spring 130 from disengaging from the limiting hole 150. When water no longer flows through the flexible tube 320, the flexible tube 320 is no longer deformed by water pressure. At this time, the elastic force stored in the spring 130 when the movable part 140 moved outward will drive the movable part 140 to reset. The tail of the movable part 140 and the switch button of the elastic switch are disconnected, and the unit controlled by the elastic switch is turned off. If the control unit is a germicidal lamp, then the germicidal lamp should be turned off at this time.

[0031] The spring 130 and the movable part 140 together form an elastic trigger.

[0032] The flexible tube 320 and the end cap 310 can be made of rubber or silicone, which gives the water-passing component 300 a certain degree of elasticity, allowing the flexible tube 320 to maintain its elasticity between expansion and contraction to prevent damage. In addition, it ensures that the end cap 310 and the support component 100 maintain good sealing performance when pressed together.

[0033] Furthermore, such as Figure 3 As shown, the sealing element is a fixing member 200 set at the upper and lower ends of the end cap 310. The support member 100 also has evenly distributed snap-fit ​​points 110. The end of the fixing member 200 also has a buckle 210, which is embedded in the snap-fit ​​point 110. The support member 100 also includes an internally formed pressure block 220, which is used to press against the upper end face of the end cap 310 to fix the beginning and end ends of the water passage member 300. In addition, the pressure block 220 has a through hole corresponding to the water passage hole of the water passage member 300, and the through holes of the two are the same size. Furthermore, the pressure block 220 can make the end cap 310 and the support member 100 tightly pressed together to ensure sealing.

[0034] Example 2:

[0035] like Figure 4-5 As shown, the difference from Embodiment 1 is that the elastic trigger is a movable spring 120 disposed outside the flexible tube 320. The movable spring 120 is L-shaped, with one end fixed inside the support member 100 and the other end extending into the limiting hole 150. Similarly, when water flows through the flexible tube 320, the flexible tube 320 expands outward due to the water pressure. At this time, the end of the movable spring 120 located in the limiting hole 150 is squeezed outward and moves outward, contacting the switch button of the elastic switch, triggering the unit controlled by the elastic switch to turn on (such as a germicidal lamp). When there is no more water flowing through the flexible tube 320, and there is no water pressure, the elasticity of the movable spring 120 itself will restore its original shape. Therefore, the end of the movable spring 120 in the limiting hole 150 is retracted and disengaged from the switch button of the elastic switch, and the unit controlled by the elastic switch is turned off.

[0036] The movable spring 120 is made of stainless steel or other elastic material.

[0037] Example 3:

[0038] like Figure 6 As shown, the difference from Embodiments 1 and 2 is that the sealing element is a sealant 230 disposed in the gap between the end cap 310 and the support member 100. The sealant 230 seals the gap between the end cap 310 and the support member 100, ensuring that the flexible tube 320 has sufficient water pressure to expand outward when water flows through it.

[0039] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
