Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of trigger switches, and in particular relates to an active trigger component. Background Art
[0002] Certain control components can be set up in the waterway through which the fluid flows to perform functions such as sterilization or heating on the fluid. These control components need to be controlled by switches to be normally open or normally closed under specific circumstances. Existing switches generally use floating magnetic switches, which control the switch according to the water level. However, the disadvantage of floating magnetic switches is that the float is prone to getting stuck. To this end, we propose an active trigger component that relies solely on fluid pressure to trigger the switch to solve the above problem. Utility Model Content

[0004] The technical solution of the present utility model is achieved as follows:

The fluid buffer chamber also has a chamber bottom. Both the fluid buffer chamber and the chamber bottom are made of elastic material.

[0007] An elastic conductive member is provided at the lower end of the fluid buffer chamber, and the elastic conductive member is in contact with the chamber bottom;
[0008] When the bottom of the silo is filled with fluid, pressure is generated on the elastic conductive member, and the elastic conductive member is pressed downward to contact the switch, so that the switch is normally open. When there is no fluid at the bottom of the silo, the elastic conductive member moves upward by its own elastic force and resets to separate from the switch, so that the switch is normally closed.
[0009] Furthermore, the structural member is a hollow structure with openings at both ends, and a fluid inlet is provided at the upper end for fluid to enter.
[0010] Furthermore, the drainage channel includes fluid outlets opened in front and behind the structural member, and a fluid outflow channel is also opened in the shell and the fluid outlet, and the outlet end of the fluid outlet and the inlet end of the fluid outflow channel are interconnected.

A mounting groove is provided in the middle part of the movable part, and a spring is embedded in the mounting groove. The movable part is a T-shaped structure, and its two ends are limitedly set along the inner side of the shell, and the bottom end of the spring is embedded in the bottom wall of the cavity.
[0012] Furthermore, the conductive sheet is a straight plate structure.
[0013] Furthermore, both ends of the conductive piece are provided with hook-shaped contacts.
[0014] Furthermore, a conducting component active area is formed correspondingly between the lower portion of the shell and the conducting sheet.
[0015] Furthermore, the conducting piece is integrally provided with the movable part, and the conducting piece is located on the lower outer side of the movable part.

DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] First embodiment:
[0032] like Figure 1-5 As shown, an active triggering member includes a structural member 10 and a housing 20, wherein the structural member 10 is fixedly installed in the housing 20, and an elastic conductive member 40 is also provided along the housing 20;
[0033] Among them, Figure 2 As shown, the structural member 10 is a hollow structure with openings at both ends. A fluid inlet 11 is provided at the upper end of the structural member 10 for the entry of fluid, and a fluid buffer chamber 30 is provided at the outlet at the lower end of the structural member 10. The upper end of the fluid buffer chamber 30 is provided with an opening, and the fluid entering through the fluid inlet 11 at the upper end of the structural member 10 enters the fluid buffer chamber 30.
[0034] Among them, Figure 3 As shown, the fluid buffer chamber 30 also has a chamber bottom 31. Both the fluid buffer chamber 30 and the chamber bottom 31 are elastic, and their materials can be elastic silicone or rubber. Figure 2-3As shown, the fluid buffer tank 30 also has an edge portion, the upper and lower ends of which are pressed onto the outlet of the structural member 10 and the step formed by the shell 20, respectively. The structural member 10 is fixed to the shell 20 by a threaded connection. This structure ensures that the fluid at the outlet of the lower end of the structural member 10 can only flow into the fluid buffer tank 30 and its bottom 31, preventing water seepage and leakage. Under the pressure of the fluid, the bottom 31 will move downward.
[0035] An elastic conductive member 40 is provided along the bottom of the bin bottom 31. Figure 2 As shown, the elastic conductive member 40 includes a conductive piece 401, the upper end of the conductive piece 401 is in contact with the bottom 31 of the bin, and the lower end is fixedly connected to a movable piece 402, the movable piece 402 is T-shaped, and a cavity 22 is opened on the inner side of the lower part of the shell 20 corresponding to the movable piece 402. The cavity 22 can just accommodate the vertical linear movement of the movable piece 402 and play a limiting role. The movable piece 402 is T-shaped, and a mounting groove 403 is opened in the middle part. A spring 404 is also provided in the groove. The bottom end of the spring 404 is placed at the bottom of the mounting groove 403. The lower part of the shell 20 is also connected to the conductive piece 401. The conductive piece 401 can move up and down along the conductive piece movable area 21. When the fluid enters the structural member 10 through the fluid inlet 11, the fluid will flow downward into the fluid buffer chamber 30 and fall on the chamber bottom 31. The chamber bottom 31 is subjected to the fluid pressure to press the conductive piece 401 downward. A switch is also provided at the lower end of the conductive piece 401. The conductive piece 401 presses down to open the switch. The switch can be a spring switch. This type of switch can be normally open when there is pressure. When there is no pressure, the spring 404 or the elastic conductive piece 40 resets to make the switch normally closed. The switch can be used to control other components, such as the normally open or normally closed function of the sterilization system.
[0036] In order to ensure that the elastic conductive member 40 can be normally reset when no fluid passes through, such as Figure 2 and Figure 4 As shown, fluid outlets 12 are further provided at the front and rear ends of the structural member 10, and fluid outflow channels 50 are further provided at positions corresponding to the outlet ends of the fluid outlet 12 in the housing 20, so that the fluid can also be discharged along the drainage channel formed by the fluid outlet 12 and the fluid outflow channel 50. When no fluid enters the structural member 10, the water flow in the structural member 10 will be preferentially discharged along the fluid outlet 12 and the fluid outflow channel 50. When the fluid pressure in the fluid buffer chamber 30 is insufficient, the elastic force of the spring 404 will force the conductive piece 401 to move upward and disengage from the switch. Just like the spring switch mentioned above, it will be normally closed in the absence of external pressure. At this time, the component controlled by the switch is closed, thus achieving the goal of actively triggering the opening and closing of the switch by the fluid.
[0037] The second embodiment is different from the first embodiment in that Figure 6As shown, the conducting piece 401 is designed as a straight plate with hook-shaped contacts 405 at both ends. The working principle is the same as the above, the conducting piece 401 is pressed down by the fluid pressure, and the contact 405 triggers the normally open state of the switch. When there is no fluid pressure, the spring 404 still assumes the reset function, the contact 405 disengages the switch, and the normally closed switch controls the corresponding component to be closed.
[0038] The third embodiment is different from the first and second embodiments in that Figure 7 As shown, the conducting piece 401 can also be integrally formed with the movable part 402. The conducting piece 401 can be arranged on the lower part or the middle side wall of the movable part 402. The conducting piece 401 can move along the cavity 22. The spring switch is also arranged on the bottom wall of the cavity 22. Similarly, the conducting piece 401 of the above two embodiments can also be integrally arranged with the upper end surface of the movable part 402. For the third embodiment, the housing 20 can abandon the conducting part active area 21 to reduce the difficulty of the processing process.
[0039] The fourth embodiment is different from the first three embodiments in that Figure 8 As shown, the elastic conductive member 40 can also be an elastic sheet, which can be a metal sheet with rebound elasticity or a plastic sheet with elasticity itself or other materials. The elastic conductive member 40 is also arranged in the cavity 22. The shape of the elastic conductive member 40 can be as follows Figure 8 The cross-section shown is a thin sheet in the shape of a trapezoidal frame, but it can also be a thin sheet in other shapes, so that the bottom of the elastic conductive member 40 can contact the spring switch, and when there is no fluid pressure at the bottom of the bin 31, due to its own rebound characteristics, the elastic conductive member 40 is used to elastically recover one end of the spring switch, thereby disconnecting from the spring switch. In this embodiment, there is no need to set a conductive member active area 21.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
