Abstract
Description
Technical Field
[0001] The utility model relates to the field of connecting rod mechanisms, in particular to a switch trigger connecting rod mechanism. Background Art
[0002] As people's living standards continue to improve, small household cleaning devices such as steam mops and hanging irons are becoming increasingly popular. These devices generally have a water tank and a steam generator, which generates high-temperature steam by heating the water in the water tank and sprays it from a nozzle to improve the cleaning effect. However, in the prior art, most of these cleaning devices use a key (button) to control the steam spray, that is, steam is sprayed when the key is pressed, and the steam spray stops when the key is released. In scenarios where long-term steam spray cleaning is required, users need to press the button continuously, which is easy to feel tired. In addition, the flexibility of the user's hand decreases when pressing, and it is difficult to move the cleaning device, which reduces the cleaning efficiency and the overall user experience is not good. Utility Model Content
[0003] The utility model aims to overcome the shortcomings of the prior art and provide a switch trigger linkage mechanism, which replaces the existing button (key) pressing form with a trigger pulling form, which is more labor-saving when used.
[0004] The purpose of the utility model is achieved through the following technical solutions: the switch trigger linkage mechanism is installed in a shell, including a trigger, a connecting rod, a linkage trigger, a steam push rod and a water tank, the trigger is rotatably connected in the shell, the front end of the trigger is exposed from a reserved hole on the shell for pulling, the rear end of the trigger is hinged with the front end of the connecting rod, the rear end of the connecting rod is hinged with the front end of the linkage trigger, and the rear end of the linkage trigger is fixedly connected with the front end of the steam push rod; a control port is provided at the front end of the water tank, a steam outlet is provided at the rear end of the water tank, and the rear end of the steam push rod extends into the water tank from the control port to control the on and off of the steam outlet to achieve steam spray control; a torsion spring is sleeved on the linkage trigger and rotatably connected in the shell, when the trigger is released, the torsion spring drives the linkage trigger to reset, thereby pulling the steam push rod to close the steam outlet.
[0005] As a further technical solution, a first support column and a second support column are arranged in the shell, the trigger is rotatably connected to the first support column, and the linkage trigger is rotatably connected to the second support column.
[0006] As a further technical solution, the front end of the connecting rod is hinged to the trigger through a pin, and the rear end of the connecting rod is hinged to the linkage trigger through a pin.
[0007] As a further technical solution, a steam hole is opened on the inner wall of the water tank near the steam outlet, and a sealing ring is installed after the steam push rod passes through the steam hole. Under the natural state, the sealing ring presses and seals the steam hole; when the trigger is pulled, the linkage trigger pushes the steam push rod, so that the sealing ring is separated from the steam hole and the steam outlet is opened.
[0008] As a further technical solution, a spray port is provided on the shell, and the steam outlet of the water tank is connected to the spray port by installing a steam spray pipe.
[0009] The beneficial effects of the utility model are:
[0010] 1. The trigger is flexible and convenient to pull, which is more labor-saving than the key (button) form, and is convenient for users to press for a long time;
[0011] 2. The connecting rod and linkage trigger are connected to the trigger to convert the rotary motion of the trigger into the linear sliding motion of the steam push rod, which is reliable and labor-saving;
[0012] 3. A sealing ring is sleeved on the steam push rod. When the steam push rod slides, it drives the sealing ring to open or seal the steam hole to achieve steam spray control. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0021] The utility model will be described in detail below with reference to the accompanying drawings:
[0022] Example: As shown in the attached Figures 1 to 7As shown, the switch trigger linkage mechanism includes a housing 1, a trigger 2, a first support column 3, a pin 4, a connecting rod 5, a linkage trigger 6, a second support column 7, a torsion spring 8, a steam push rod 9, a water tank 10, a control port 11, a steam outlet 12, a steam hole 13, a sealing ring 14, a steam spray pipe 15, a spray port 16 and a reserved hole 17.
[0023] Reference Figure 1 , 2 The housing 1 is composed of two parts, the left and right parts, and the first support column 3 and the second support column 7 are arranged in the housing 1. The trigger 2 is rotatably connected to the first support column 3, and the linkage trigger 6 is rotatably connected to the second support column 7. At the same time, a reserved hole 17 is opened in the center of the housing 1, so that the front end of the trigger 2 is exposed from the reserved hole 17 on the housing 1 for the user to pull it. Figure 3 , 4 As shown, the rear end of the trigger 2 is hinged to the front end of the connecting rod 5 through the pin 4, the rear end of the connecting rod 5 is hinged to the front end of the linkage trigger 6 through the pin 4, and the rear end of the linkage trigger 6 is fixedly connected to the front end of the steam push rod 9.
[0024] Further, such as Figure 5 As shown, a control port 11 is provided at the front end of the water tank 10, and a steam outlet 12 is provided at the rear end of the water tank 10. The rear end of the steam push rod 9 extends from the control port 11 into the water tank 10 to control the on and off of the steam outlet 12 to achieve steam spray control. A torsion spring 8 is also sleeved on the linkage trigger 6, and the torsion spring 8 provides a reset force for the linkage trigger 6. When the trigger 2 is released, the torsion spring 8 drives the linkage trigger 6 to reset, thereby pulling the steam push rod 9 to close the steam outlet 12.
[0025] Reference Figure 6 , 7 A steam hole 13 is provided on the inner wall of the water tank 10 near the steam outlet 12. A sealing ring 14 is sleeved after the steam push rod 9 passes through the steam hole 13. In the natural state (i.e., when the trigger 2 is not pulled), the sealing ring 14 presses and seals the steam hole 13; when the trigger 2 is pulled, the linkage trigger 6 pushes the steam push rod 9, so that the sealing ring 14 is separated from the steam hole 13, thereby opening the steam outlet 12. Further, a spray port 16 is provided on the housing 1, and the steam outlet 12 of the water tank 10 is connected to the spray port 16 by installing a steam spray pipe 15.
[0026] The working process of this utility model: Figure 3 As shown in the figure, the dotted arrows in the figure show the force transmission process of the utility model. When the trigger 2 is pressed by hand, the trigger 2 rotates with the first support column 3 as the support point, and the rear end of the trigger 2 is downward, driving the connecting rod 5 to move downward. Because the linkage trigger 6 is connected to the connecting rod 5 by a pin 4, the linkage trigger 6 rotates with the second support column 7 as the support point, and the rear end of the linkage trigger 6 is upward. The steam push rod 9 moves forward under the force of the linkage trigger 6. Figure 7 As shown, the sealing ring 14 is separated from the steam hole 13, thereby opening the steam outlet 12, and the steam is ejected from the ejection port 16 along the steam ejection pipe 15. When the trigger 2 is released, the trigger 2 returns to its initial state under the action of the torsion spring 8, driving the steam push rod 9 to move backward, as shown in FIG. Figure 6 As shown, the sealing ring 14 is compressed again to seal the steam hole 13, thereby closing the steam outlet 12.
[0027] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and the concept of the utility model should fall within the protection scope of the claims attached to the utility model.
