Description

Technical Field

[0001] The utility model relates to a gas stove fitting, in particular to a stove body with a fire power feedback function. Background Art

[0002] In modern kitchen appliances, gas stoves are widely used due to their high efficiency and easy control. One of the core components of a gas stove is the valve body, which is responsible for regulating the gas flow into the burner and thus controlling the fire power. Traditional gas stove valve bodies usually include a valve housing and a rotatable valve core, and the valve core is operated by a handle connected to a valve rod. Users control the gas flow by manually adjusting the handle, thereby adjusting the fire power.

[0003] However, despite the progress made in the simplicity of operation in the prior art, they have a significant limitation: the lack of an accurate feedback mechanism for fire power. In the existing gas stove valve body designs, users cannot obtain direct feedback on the actual fire power. This is mainly because the valve body design only allows mechanical switching and adjustment, without integrating any form of sensing element to monitor or report the exact position of the valve core or the corresponding gas output. Therefore, users have to rely on experience to judge the fire power, which may lead to unsatisfactory results during the cooking process that requires precise control of the fire power.

[0004] In addition, the existing gas stove control systems have also failed to integrate an effective fire power monitoring mechanism. This means that when the gas stove is operating, its control system cannot adjust or optimize the combustion conditions in real time to adapt to different cooking requirements or environmental changes. For example, changes in the external air pressure or fluctuations in the gas pressure may affect the fire power output, and the traditional system cannot automatically adjust to maintain the set cooking conditions.

[0005] Another consequence of the lack of fire power feedback is a safety issue. Without precise control and feedback, excessive or insufficient fire power may lead to cooking accidents, such as food burning or an increased risk of fire.

[0006] Therefore, in order to overcome these limitations of the prior art, there is an urgent need for a gas stove valve body design that can provide real-time fire power feedback. Such a design should be able to accurately monitor the position of the valve core through modern sensing technology and provide accurate fire power information to the user or the control system through a suitable feedback mechanism, so as to achieve accurate control of the working state of the gas stove. Summary of the Utility Model

[0007] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a stove body with a fire power feedback function that has a simple structure, is easy to use, can real-time feedback the position of the fire power regulating valve body, and is convenient for users and the control system to perceive the fire power.

[0008] The object of the present utility model is achieved in the following way: A cooking stove valve body with a fire power feedback function, which includes a valve housing. A valve core is rotatably installed in the valve housing. The valve core is connected to a valve rod, and a handle is arranged on the valve rod. When the handle rotates, it drives the valve core to rotate through the valve rod to control the combustion of the cooking stove;

[0009] Wherein, a fire power feedback device is further connected to the valve core or the valve rod. The fire power feedback device outputs corresponding control electrical signals according to the position of the valve core.

[0010] Further: The fire power feedback device is a cam installed on the valve core or the valve rod. A position switch is further included. When the cam rotates to a set position, it triggers the position switch to generate a control electrical signal.

[0011] Further: A connection hole is arranged in the middle of the cam. The connection hole is sleeved on the valve rod and moves synchronously with the valve rod.

[0012] Further: When the cam rotates to 75° - 105°, it triggers the position switch.

[0013] Further: The fire power feedback device is a potentiometer installed on the valve core or the valve rod.

[0014] Further: The fire power feedback device is an encoder installed on the valve core or the valve rod.

[0015] The beneficial effects of the present utility model are: 1. The structure is simple, the production cost is low, and the market competitiveness is improved.

[0016] 2. The traditional gas stove valve body lacks direct feedback on the fire power size. By installing a fire power feedback device on the valve core or the valve rod in the present invention, corresponding control electrical signals can be output according to the position of the valve core. This function, combined with the main control system, enables users to precisely adjust the fire power, avoiding the uncertainty of judging the fire power size by experience and improving the precision and consistency of cooking.

[0017] 3. The fire power feedback function of the present invention provides a basis for the realization of the intelligent control system of the gas stove. The control system can automatically adjust the gas output through the feedback signal to realize the dynamic optimization of the combustion process. This not only improves the gas utilization efficiency but also can maintain the best fire power level under various cooking conditions, thereby enhancing the user's cooking experience.

[0018] 4. The present invention provides a variety of choices for the fire power feedback device, such as a cam, a position switch, a potentiometer or an encoder installed on the valve core or the valve rod. The diversity of these devices makes the present invention highly adaptable, and the appropriate feedback method can be selected according to specific requirements to achieve the best fire power control effect.

[0022] The following further specifically describes the present utility model in conjunction with the attached drawings. A stove valve body with a fire power feedback function includes a valve housing 1, a valve core 2 is rotatably installed inside the valve housing 1, the valve core 2 is connected to a valve rod 3, a handle is arranged on the valve rod 3, and when the handle rotates, the valve core 2 is driven to rotate through the valve rod 3 to control the combustion of the stove;

[0023] Among them, a fire power feedback device is further connected to the valve core 2 or the valve rod 3, and the fire power feedback device outputs a corresponding control electrical signal according to the position of the valve core 2.

[0024] In one embodiment, the fire power feedback device is a cam 4 installed on the valve core 2 or the valve rod 3, and a position switch 5 is further included. When the cam 4 rotates to a set position, the position switch 5 is triggered to generate a control electrical signal.

[0025] In one embodiment, a connection hole 6 is arranged in the middle of the cam 4, and the connection hole 6 is sleeved on the valve rod 3 and moves synchronously with the valve rod 3.

[0026] In one embodiment, when the cam 4 rotates to 75° - 105°, the position switch 5 is triggered.

[0027] In one embodiment, the fire power feedback device is a potentiometer installed on the valve core 2 or the valve rod 3.

[0028] In one embodiment, the fire power feedback device is an encoder installed on the valve core 2 or the valve rod 3.

[0029] Working principle: The stove valve body of the present invention includes a valve housing (1), a valve core (2) is rotatably installed inside the valve housing, and the valve core is connected to a valve rod (3). The user operates the valve rod through the handle to drive the valve core to rotate, thereby controlling the gas flow rate and realizing the fire power adjustment.

[0030] Among them, a fire power feedback device is installed on the valve core or the valve rod, and this device outputs a corresponding control electrical signal according to the position of the valve core. The fire power feedback device can be in various forms, such as a combination of a cam (4) and a position switch (5), a potentiometer or an encoder.

[0031] During use, when the valve core rotates through the valve stem, the cam (4) installed on the valve core or valve stem also rotates synchronously. When the cam rotates to a specific angle (such as 75° - 105°), it triggers the position switch (5), and the position switch generates a control electrical signal, which reflects the current position of the valve core, thereby indirectly reflecting the gas flow rate and the size of the flame.

[0032] Among them, when the potentiometer is assembled and used, it is installed on the valve core or valve stem. As the valve core rotates, the resistance value of the potentiometer changes, and a corresponding electrical signal is output. This electrical signal precisely corresponds to the position of the valve core, realizing real-time feedback on the flame.

[0033] Among them, when the encoder is assembled and used, the encoder can accurately measure the angular position of the valve core and output a digital signal. Through the signal output by the encoder, the control system can understand the position of the valve core in real time, thereby precisely controlling combustion.

[0034] The generated control electrical signal can be transmitted to the control system of the gas stove. The control system adjusts the control strategy in real time according to the received signal, or displays the flame condition through the display device to ensure that the combustion state meets the preset flame requirements. This can not only achieve precise flame control but also improve the utilization efficiency of gas and the quality of cooking.

[0035] Compared with the traditional technology, the flame feedback device can monitor the position of the valve core in real time and output the corresponding electrical signal, enabling the gas stove to precisely control the gas flow rate according to the feedback signal. Users can accurately adjust the flame according to the feedback information, and the cooking process is more precise and controllable.

[0036] In addition, due to the ability to provide real-time feedback on the flame information, users can adjust the flame in a timely manner to avoid potential safety hazards caused by too large or too small a flame. For example, preventing food from burning or gas leakage, significantly improving the safety of the gas stove, so it can be widely promoted and used.

[0037] The installation buckle of the built-in range hood of the present invention realizes the rapid installation, firm fixation and height adjustment of the range hood through the coordinated action of structures such as the slideway, adjustment screw, guide seat and hanging plate. It improves the convenience of installation and adjustment, greatly improves the installation efficiency of the range hood, so it can be widely promoted and used.

[0038] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
