Description

Technical Field

[0001] This utility model relates to the field of industrial equipment parts technology, specifically a clamp valve. Background Technology

[0002] A clamp valve is a common industrial equipment component that can be used to loosen / clamp a flexible air tube (which connects the air source and the air-using device to form an air path) to open / close the air path between the air source and the air-using device.

[0003] There are many ways to drive pinch valves, such as electromagnetic drive, motor drive, pneumatic drive, hydraulic drive and manual drive. However, no matter which drive method is used, pinch valves can only achieve two working states, namely triggered and not triggered, and the corresponding air circuit working states are only open and closed.

[0004] In the field of electronic cigarette testing equipment, it is often necessary to gradually adjust parameters such as air pressure / flow rate in the gas path. However, the pinch valves in the existing technology can only achieve two working states, and the corresponding gas path working states are only open and closed, which cannot realize the proportional adjustment of the gas path, and therefore cannot adjust parameters such as air pressure / flow rate in the gas path. Although the air pressure / flow rate in the gas path can be adjusted on the gas source side, the requirements for the gas source itself are high, which makes the material cost and control cost of the gas source high.

[0005] In summary, how to provide a pinch valve suitable for proportionally adjusting parameters such as air pressure / flow rate in the gas circuit has become one of the urgent problems to be solved. Utility Model Content

[0006] The purpose of this invention is to provide a pinch valve that is suitable for proportionally adjusting parameters such as air pressure / flow rate in the air circuit.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a clamp valve, comprising a motor, a clamp valve base, and a clamping actuating component; the motor shaft is configured as an output screw; the clamp valve base has an airway channel suitable for a flexible airway to pass through, and an actuating groove communicating with the airway channel; the clamping actuating component has a screw connection hole adapted to the output screw of the motor; the output screw of the motor is connected to the screw connection hole of the clamping actuating component; the clamp valve base is fixed to one side of the motor, such that the actuating groove of the clamp valve base covers the clamping actuating component; the motor can drive the clamping actuating component to move forward and backward along a direction close to or away from the airway channel, using at least one of stroke control and proportional control.

[0008] In the above technical solution, the motor is one of a DC motor, a servo motor, and a stepper motor.

[0009] In the above technical solution, the contact end of the clamping action component is configured as a convex rib.

[0010] In the above technical solution, the surface of the clamping action component is embedded with guide balls; the action groove of the clamping valve base is provided with a guide groove; the guide balls of the clamping action component can roll in the guide groove of the clamping valve base.

[0011] In the above technical solution, an opening is also formed at the base of the clamp valve that communicates with the air pipe channel, and the opening is connected to the outside of the clamp valve base.

[0012] In the above technical solution, the clamp valve base is equipped with an adjusting shaft that can be connected to the airway channel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The clamp valve of this utility model has a motor that can drive the clamping action component to move forward and backward along the direction close to or away from the air tube channel in at least one of the stroke control and proportional control methods. It can not only loosen / clamp the flexible air tube (which is connected between the air source and the air-using device to form an air path) to open / close the air path between the air source and the air-using device, but also proportionally adjust parameters such as air pressure / flow rate in the air path, making the clamp valve more widely applicable and adaptable to various electronic cigarette detection devices.

[0019] 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.

[0020] This embodiment provides a clamp valve for loosening / clamping a flexible air tube (which is connected between the air source and the air-using device to form an air path) to open / close the air path between the air source and the air-using device, and can proportionally adjust parameters such as air pressure / flow rate in the air path.

[0021] Please see Figures 1-3 The clamp valve in this embodiment includes a motor 1, a clamp valve base 2, and a clamping action component 3.

[0022] The motor 1 is one of a DC motor, a servo motor, and a stepper motor, and its rotation angle can be controlled by a host computer. The clamp valve base 2 is an integrally formed shell-shaped metal component, which serves as the structural support and functional basis of the clamp valve in this embodiment. The clamping action component 3 is an integrally formed solid metal component, which serves as the functional basis of the clamp valve in this embodiment.

[0023] The shaft of motor 1 is configured as an output screw 11, that is, the shaft of motor 1 has a screw-type external thread.

[0024] The base of the clamp valve has two parts: an air passage 21 suitable for a flexible air tube to pass through, and an actuation groove 22 connected to the air passage 21; wherein the air passage 21 is a circular hole and the actuation groove 22 is a circular groove.

[0025] The clamping action component 3 has a screw connection hole 31 that is compatible with the output screw 11 of the motor 1, that is, the screw connection hole 31 of the clamping action component 3 has a screw-type internal thread.

[0026] The output screw 11 of the motor 1 is connected to the screw hole 31 of the clamping action component 3 (the two are threaded together), and the clamping valve base 2 is fixed on one side of the motor 1 (specifically, by screws), so that the action groove 22 of the clamping valve base 2 covers the clamping action component 3; the motor 1 can drive the clamping action component 3 to move forward and backward in the direction of approaching or moving away from the airway channel 21, in at least one of the methods of stroke control and proportional control.

[0027] Furthermore, the contact end of the clamping action member 3 is configured as a convex rib 33. In this embodiment, the convex rib 33 is a frustum-shaped rib. Configuring the contact end of the clamping action member 3 as a convex rib 33 can increase the pressure of the clamping action member 3 on the flexible airway, making the flexible airway more easily deformable.

[0028] Furthermore, the surface of the clamping action component 3 is embedded with guide balls 32, which are specifically steel balls; the action groove 22 of the clamping valve base 2 is provided with a guide groove 221, which is specifically a straight groove; the guide balls 32 of the clamping action component 3 can roll in the guide groove 221 of the clamping valve base 2, thereby guiding the movement of the clamping action component 3.

[0029] Furthermore, an opening 23 is formed at the clamp valve base 2, which is connected to the air passage 21. The opening 23 is connected to the outside of the clamp valve base 2, so that the flexible air tube can enter the air passage 21 of the clamp valve base 2 laterally.

[0030] Furthermore, the clamp valve base 2 is equipped with an adjusting shaft 24 that can be connected to the airway channel 21. Specifically, the adjusting shaft 24 is an eccentric shaft that is laterally inserted into the clamp valve base 2 and fixed by screws 241. By rotating the adjusting shaft 24, flexible airways of different radii can be adapted.

[0031] Please see Figure 4 The clamp valve in this embodiment can also be configured as a double-pipe clamp valve. It is only necessary to configure two air pipe channels 21 at the clamp valve base 2 and configure the clamping action member 3 to reciprocate translational motion (of course, the protruding ribs 33 of the clamping action member 3 are configured as two opposite locations).

[0032] In this embodiment, the clamp valve's motor 1 can drive the clamping action component 3 to move forward and backward along the direction close to or away from the air pipe channel 21, using at least one of stroke control and proportional control. This not only allows the clamp to release / clamp the flexible air pipe (which connects the air source and the air-using device to form an air path) to open / close the air path between the air source and the air-using device, but also allows for proportional adjustment of parameters such as air pressure / flow rate in the air path. This makes the clamp valve more widely applicable and compatible with various electronic cigarette detection devices.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
