[0049] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0050] See Figure 1 Figure 11 , which shows a foot-operated control switch according to a preferred embodiment of the present utility model, including:

[0051] Installation base 1;

[0052] Main control circuit board 2, the main control circuit board 2 is arranged inside the installation base 1, and the main control circuit board 2 is used for electrically connecting with the device to be controlled;

[0053] First button switch 3, the first button switch 3 is electrically connected with the main control circuit board 2, the first pressing part of the first button switch 3 is exposed at the top of the installation base 1, and the first button switch 3 is used to control any one or combination of the opening, closing, temperature, wind speed, timing, power of the device to be controlled;

[0054] Display screen 4, the display screen 4 is arranged on the top of the installation base 1, the display screen 4 is electrically connected with the main control circuit board 2, and the display screen 4 is used to display the working state of the device to be controlled.

[0055] For the foot-operated control switch of the present utility model, pressing the first button switch 3 can be achieved by stepping on the first pressing part of the first button switch 3, and releasing the first button switch 3 can reset the first button switch 3, which can connect or disconnect the circuit to control the operation of the device to be controlled. For example, it can control any one or combination of the opening, closing, temperature, wind speed, timing, power of the device to be controlled, etc., and has a foot-operated control function. At the same time, since a display screen 4 is arranged on the top of the installation base 1, the display screen 4 can be electrically connected with the main control circuit board 2, and the display screen 4 can display the working state of the device to be controlled. For example, it can display the opening state, closing state, temperature, wind speed, timing state, power of the device to be controlled, etc., making the working state of the device to be controlled visual, having a display function, and improving the utilization rate of the foot-operated control switch.

[0056] See Figure 4 , in one embodiment, the foot-operated control switch further includes:

[0057] The second button switch 5 is electrically connected to the main control circuit board 2. The second pressing portion of the second button switch 5 is exposed on the side of the mounting base 1. The second button switch 5 is used to control the operation of the device to be controlled. In this way, by operating the second button switch 5, any one or combination of turning on, turning off, temperature, wind speed, timing, and power of the device to be controlled can be realized, or the control of different functions of the device to be controlled can be realized. For example, the first button switch 3 is used to control the turning on and off of the device to be controlled, while the second button switch 5 can be used to control the temperature, wind speed, etc. of the device to be controlled, making the functions of the foot-operated control switch diversified, which can further improve the utilization rate of the foot-operated control switch. At the same time, it can also meet the usage requirements of different users.

[0058] In one embodiment, the number of the second button switches 5 can be multiple. The multiple second button switches 5 are respectively used to control different function adjustments of the device to be controlled to achieve function diversification. At the same time, the utilization rate of the foot-operated control switch is further improved.

[0059] It can be understood that the first button switch 3 and the second button switch 5 are also called control buttons (abbreviated as buttons). They are low-voltage electrical appliances that can be foot-operated and generally can be automatically reset. Button switches are usually used in circuits to issue start or stop instructions to control the on (i.e., electrical connection) and off (i.e., electrical disconnection) of the coil currents of electrical appliances such as electromagnetic starters, contactors, and relays.

[0060] See Figures 2 - 11 , in one embodiment, the first button switch 3 includes:

[0061] A button seat (not shown in the figure), the button seat is movably arranged, and the button seat is exposed on the mounting base 1. The above-mentioned first pressing portion is arranged on the button seat;

[0062] A button protection cover 31, the button protection cover 31 is sleeved on the button seat, and the button protection cover 31 is a structure made of silicone or rubber material. Since the button protection cover 31 is a structure made of silicone or rubber material, the button protection cover 31 has a certain elasticity and flexibility, can play a certain buffering role, making the button seat not easily damaged by stepping on, and at the same time, making the button protection cover 31 durable and wear-resistant, so as to extend the service life of the first button switch 3.

[0063] See Figure 11 , in one embodiment, a plurality of anti-slip protrusions 311 are provided on the top of the button protection cover 31, and the plurality of anti-slip protrusions 311 are arranged at intervals. In this way, when stepping on the first button switch 3, the anti-slip protrusions 311 come into contact with the foot and can increase the friction between it and the foot, restricting the relative sliding of the foot with respect to the first button switch 3, playing an anti-slip role, and ensuring that the first button switch 3 can be stepped on.

[0064] See Figure 11 In one embodiment, the top surface of the anti-slip protrusion 311 is a flat surface, that is, the surface of the anti-slip protrusion 311 in contact with the human foot is a flat surface, which increases the contact area between the anti-slip protrusion 311 and the human foot, thereby achieving a good anti-slip effect.

[0065] In other embodiments, the top surface of the anti-slip protrusion 311 may be a convex arc surface.

[0066] In one embodiment, the button protection cover 31 has a connection groove (not shown in the figure) inside, and the connection groove is arranged around the outer peripheral surface of the button seat;

[0067] The outer peripheral surface of the button seat (not shown in the figure) is provided with a connection protrusion (not shown in the figure), and the connection protrusion is adapted to the connection groove to limit the button protection cover 31 from disengaging upward from the button seat, that is, to prevent the button protection cover 31 from falling off, ensuring that the button protection cover 31 can be reliably sleeved on the button seat, thereby playing a protective role for the button seat.

[0068] In one embodiment, the installation base 1 includes:

[0069] An installation main body 11, on which the main control circuit board 2, the first button switch 3 and the display screen 4 are all arranged, and the bottom of the installation main body 11 has a first connection hole 1111;

[0070] A connecting plate 12, which is located below the bottom of the installation main body 11. An avoidance gap 13 is formed between the connecting plate 12 and the installation main body 11, and the avoidance gap 13 is used to be adapted to the controlled device. The connecting plate 12 has a second connection hole 121;

[0071] A fastener, the head of the fastener abuts against the bottom of the connecting plate 12, the rod portion of the fastener sequentially passes through the second connection hole 121, the controlled device, and the first connection hole 1111, and the rod portion of the fastener is screwed with the first connection hole 1111. In this way, the controlled device can be located in the avoidance gap 13, and then the connecting plate 12, the controlled device and the installation main body 11 are connected by the fastener, so that the connecting part is clamped between the connecting plate 12 and the installation main body 11, thereby realizing the fixation of the installation base 1 on the controlled device, that is, fixing the foot-operated control switch on the controlled device.

[0072] In other embodiments, the foot-operated control switch can be directly placed on the ground.

[0073] See Figures 2 - 4 In one embodiment, the main body 11 of the installation base 1 includes:

[0074] A base 111, on which the main control circuit board 2 is arranged on the top surface;

[0075] The top cover 112 is disposed on the base 111. The top cover 112 and the base 111 form a receiving cavity, which houses at least part of the main control circuit board 2 and the first button switch 3. The top of the top cover 112 has an avoidance hole 1121 through which the first pressing portion passes. In this way, during installation, first install the main control circuit board 2 on the top surface of the base 111, and then cover the top cover 112 on the base 111 to complete the installation. The installation operation is simple, convenient, and has high installation efficiency.

[0076] See Figure 4 , in one embodiment, among the base 111 and the top cover 112, one is provided with a clamping groove 1122, and the other is provided with a clamping protrusion 1112. The clamping protrusion 1112 cooperates with the clamping groove 1122 to connect the base 111 and the top cover 112 together. That is, the base 111 and the top cover 112 are connected together by a clamping method, and the clamping method is a screw-free connection method. No auxiliary tool is required during the installation process, which is convenient for quickly installing the base 111 and the top cover 112 together, making the installation operation more convenient and conducive to further improving the installation efficiency.

[0077] See Figure 4 , in one embodiment, the number of both the clamping grooves 1122 and the clamping protrusions 1112 is multiple. The multiple clamping grooves 1122 and the clamping protrusions 1112 are both arranged at intervals around the connection between the base 111 and the top cover 112. The clamping protrusion 1112 is adapted to a corresponding clamping groove 1122 to reliably fix the base 111 and the top cover 112 together.

[0078] In other embodiments, the base 111 and the top cover 112 can also be connected together by fasteners. Specifically, the fasteners can be any one or a combination of screws, bolts, rivets, etc.

[0079] See Figures 3 - 4 , in one embodiment, among the base 111 and the top cover 112, one is provided with a positioning groove 1123, and the other is provided with a positioning protrusion 1113. The positioning protrusion 1113 cooperates with the positioning groove 1123 to play a role in installation positioning, which is conducive to further improving the installation efficiency of the base 111 and the top cover 112.

[0080] See Figure 10 , in one embodiment, the foot pedal control switch further includes:

[0081] A temperature sensor 6, which is electrically connected to the main control circuit board 2. The temperature sensor 6 is located outside the installation base 1 and is used to detect the ambient temperature of the device to be controlled;

[0082] The main control circuit board 2 is also used to control the display screen 4 to display the ambient temperature of the controlled device according to the first feedback information of the temperature sensor 6, so as to visualize the real-time ambient temperature of the controlled device. The main control circuit board 2 is also used to control the controlled device to shut down according to the second feedback information of the temperature sensor 6, that is, after the temperature sensor 6 detects that the ambient temperature of the controlled device reaches the set temperature, the main control circuit board 2 controls the controlled device to shut down to stop the current output, so that the controlled device stops running. It can achieve precise temperature control and improve the use safety of the controlled device at the same time.

[0083] In one embodiment, the temperature sensor 6 is an NTC temperature sensor 6, that is, a thermosensitive temperature sensor 6, which can achieve precise temperature control.

[0084] The fixing method of this foot control switch is as follows:

[0085] It is not fixed on the controlled device, that is, it is connected to the controlled device through a switch wire, which is suitable for relatively three-dimensional controlled devices;

[0086] The connecting plate 12 is not provided, and it is fixed on the surface of the controlled device by screws or glue;

[0087] The connecting plate 12 is provided, and the controlled device is clamped between the base 111 and the connecting plate 12, so as to be fixed on the controlled device (such as Figure 6 and Figure 9 ), which is suitable for relatively flat controlled devices. Among them, in the case where the connecting plate 12 is provided, see Figures 7 - 9 , one side of the connecting plate 12 protrudes and this protrusion is connected to the base 111. The connecting plate 12 and the base 111 enclose an avoidance gap 13, which is used to be clamped on the side of the controlled device. Because the side protrusion of the connecting plate 12 will not expose the side of the controlled device, it has aesthetics (such as Figure 9 ); see Figures 2 - 6 , one side of the connecting plate 12 is not provided with a side protrusion, which is used to be clamped at any position close to the center of the controlled device (such as Figure 6 ).

[0088] A preferred embodiment of the present invention provides a space heater, that is, one of the above-mentioned controlled devices, including the above-mentioned foot control switch.

[0089] The space heater of the present invention, due to adopting the above-mentioned foot control switch, also has the functions of the foot control switch and the display function, improving the utilization rate of the foot control switch.

[0090] Among them, the space heater can specifically be large space heaters such as industrial warm air blowers, hot air drying machines, hot air dryers, electric blowers, workshop heaters, factory building heaters, paint drying machines, motor painting and drying machines, floor dryers, etc., or household appliances such as heaters and foot warmers.
