Description

Technical Field

[0001] This disclosure relates to pumps. More specifically, this disclosure relates to a control unit that allows users to operate the pump in a user-friendly and convenient manner. Background Technology

[0002] Pumps, such as battery pumps, may include a control unit for operating the pump. In this case, the control unit may include one or more buttons, switches, and indicators to allow the user to interact with different modes and functions of the pump. As the features and modes of pumps increase, there has been ongoing interest in the spatial coverage, function, and number of buttons, switches, and indicators on the pump's control unit.

[0003] Furthermore, the number of buttons, switches, and indicators on the control unit presents constraints regarding space and aesthetics. There is also a growing need to make the control unit as compact and easy to use as possible. For similar reasons, efforts have been made in the art to provide buttons, switches, or indicators on control units that can serve multiple functions and allow for better space utilization in a user-friendly manner.

[0004] EP2996442 (hereinafter referred to as '442 reference) provides an example of a signal indicator. '442 reference provides a signal indicator comprising multiple light-emitting units, each emitting light in a color selected from a plurality of light-emitting colors. A memory stores the light-emitting color information of the multiple light-emitting units, and a light-emitting control section controls the light-emitting state of the multiple light-emitting units based on the light-emitting color information stored in the input control signal. However, '442 reference does not disclose a simple, user-friendly device (such as a switch) for allowing convenient switching between different parameters, nor a suitable indicator (i.e., the light-emitting state here) to highlight changes in different parameters.

[0005] Patent reference DE102018008389 (hereinafter referred to as '389 reference) discloses a control unit for a pump. Furthermore, a drive motor and pump electronics are provided for speed-controllable drive of the motor. The operating elements are equipped with knobs to control different parameters / modes of the pump. '389 reference does not disclose a selective indication of the pump's battery status, and more specifically, it does not disclose a selective indication during the pump's dynamic operation in different operating modes. This could lead to the need for multiple light-emitting units, switches, etc., thus making the operation of the pump control unit more complex and requiring more skill.

[0006] Therefore, there is a need for an improved control unit, particularly for pumps, that provides a compact and user-friendly multi-functional user interface with buttons on the control unit. Summary of the Invention

[0007] In view of the foregoing, the object of the present invention is to solve or at least reduce the aforementioned disadvantages. This object is achieved at least in part by a control unit (particularly a control unit for a pump). The control unit includes a control button for operating the pump based on user actions. The control unit includes a plurality of light-emitting units on which the control unit is disposed. The plurality of light-emitting units indicate one or more operating parameters of the pump. The control unit is characterized in that the control button allows switching between multiple operating modes of the pump based on different user actions. Furthermore, the plurality of light-emitting units indicate the switching between the plurality of operating modes of the pump through color changes corresponding to the plurality of operating modes of the pump. Therefore, the present disclosure provides a simple, convenient, and efficient control unit for a pump that allows switching between different modes of the pump using a single button (i.e., a control button).

[0008] According to one embodiment of the invention, the plurality of operating modes includes a battery mode with a battery state, a first mode with a first operating parameter, and a second mode with a second operating parameter. This allows operation of different operating modes. For example, the first operating mode can be a battery mode, while the second operating mode can be a timer mode, thereby allowing switching between the two modes using a single button (i.e., a control button).

[0009] According to one embodiment of the present invention, different user actions include a first user action and a second user action. When the control button is actuated by the first user action, a first operation mode is activated, and when the control button is actuated by the second user action, a second operation mode is activated. This allows for easy switching between the first and second modes using a single control button through different user actions.

[0010] According to one embodiment of the present invention, the first user action is pressing the control button for a first time period, and the second user action is pressing the control button for a second time period. Thus, different operating modes on the control panel are selected based on the different time periods the user applies to the control button.

[0011] According to one embodiment of the present invention, the first mode and the second mode are the pump's power supply mode and timer mode, respectively. It will be apparent to those skilled in the art that a wide variety of operating modes and their different combinations are possible. For example, different modes may be power supply mode, timer mode, or battery status mode, etc.

[0012] According to one embodiment of the present invention, the plurality of light-emitting units are LEDs (light-emitting diodes). Using LEDs allows for easy and user-friendly visual indications, as well as other implementation benefits of LEDs.

[0013] According to one embodiment of the invention, when the pump switches between a first mode and a second mode, the plurality of light-emitting units switch between a first color and a second color. Therefore, the color change of the plurality of light-emitting units serves as a simple and easy visual indicator for verifying the change between the first mode and the second mode. Various types of multicolor LEDs are known from the prior art.

[0014] According to one embodiment of the present invention, the first color and the second color are blue and green, respectively. The selection of the first color and the second color can be based on user preference or any implementation factors.

[0015] According to one embodiment of the invention, the control unit further includes a power button for operating the pump. Thus, the control unit can be operated as needed by either the power button or the control button.

[0016] According to one embodiment of the invention, the plurality of operating modes includes a power-on / off mode for the pump. This allows a control button to be used to activate the power-on / off mode of the pump.

[0017] According to one embodiment of the invention, the number of the plurality of light-emitting units is at least three. The number of the plurality of light-emitting units can provide an indication of the pump's status, stage, or any other value related to the one or more operating parameters and modes.

[0018] According to one embodiment of the invention, the plurality of light-emitting units selectively indicate the battery state of the pump during a first operating mode and a second operating mode. This allows for dynamic indication of the pump's battery state to the user even during any active state in the first and second operating modes.

[0019] According to one embodiment of the invention, the control unit is at least partially implemented on a portable device, allowing at least a portion of different operating modes to be activated and / or switched on the portable device. This allows for remote control via a portable device such as a smartphone or tablet.

[0020] According to one embodiment of the invention, the control unit is at least partially implemented on a portable device, such that the operating parameters are at least partially visible on the user's portable device. This allows for remote inspection of the operating parameters, so that if the operating parameters are not as expected or desired, the user only needs to move closer to the controlled device, for example, in the event of a malfunction or power failure.

[0021] According to one embodiment of the invention, the control button can be integrated with a light-emitting element, such that the control button changes color based on the plurality of operating modes. Thus, the control button can additionally or alternatively serve as an indicator for changing between a first operating mode and a second operating mode based on a corresponding first or second user action performed using the control button.

[0022] According to one embodiment of the present invention, a pump having a control unit is provided. The pump may be a battery pump, or any pump with a control unit as used or known in the art.

[0023] Other features and aspects of the invention will be apparent from the following description and drawings. Attached Figure Description

[0032] The invention will be described more fully below with reference to the accompanying drawings, which illustrate exemplary embodiments of the invention incorporating one or more aspects thereof. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. For example, one or more aspects of the invention may be used in other embodiments, and even in other types of structures and / or methods. In the drawings, the same numerals denote the same elements.

[0033] Certain terms are used herein for convenience only and should not be considered as limiting the invention. For example, “upper,” “lower,” “front,” “rear,” “side,” “longitudinal,” “lateral,” “transverse,” “upward,” “downward,” “forward,” “backward,” “left,” “right,” “horizontal,” “vertical,” “upward,” “inner,” “outer,” “inward,” “outer,” “top,” “bottom,” “higher,” “above,” “below,” “center,” “middle,” “between,” “end,” “adjacent,” “near,” “far,” “radial,” “circumferential,” etc., describe only the constructions shown in the figures. In practice, components may be oriented in any direction, and therefore, the terms should be understood to cover such variations unless otherwise specified.

[0034] Figure 1 A pump 100 with a control unit 150 is shown. This disclosure illustrates a battery pump. However, the teachings of this disclosure can be implemented with any other pump, such as, but not limited to, pulse pumps, submersible pumps, speed pumps, and gravity pumps, as this disclosure is not limited in any way to the type / size / mechanism of the pump.

[0035] Figure 1 A pump 100 with a pump housing 110 is shown. The pump 100 includes a control housing 120 housing a control unit 150. The control unit 150 and the pump 100 are powered by a battery (not shown) housed within the control housing 120. The control unit 150 allows for different levels or modes of control of the pump 100. The control unit 150 may allow for various levels of control of the pump 100, such as, but not necessarily limited to, overall control of the pump 100, where the control unit 150 can be used to control any function of the pump 100 without any limitations. Furthermore, there may be situations where the control unit 150 may be able to control the pump 100 with some limitations for any reason, such as power control of the pump 100 only.

[0036] Furthermore, the control unit 150 includes a power button 160, a control button 170, and a series of light-emitting units L1, L2, L3. This disclosure provides a control unit 150 with a compact and aesthetically pleasing arrangement without compromising the ease of use and convenience of application. This disclosure further avoids the need for multiple levers, buttons, etc., to perform changes to various modes and parameters operable by the control unit 150 of the pump 100. This allows for easy operation of the pump 100 by a common operator while providing multiple functions without relying on multiple buttons on the control unit 150 to control the pump 100.

[0037] In one embodiment, the pump housing 110 and the control housing 120 are made of any material, such as a waterproof material. For aesthetic and practical benefits, the control housing 120 may be made of a transparent material. Furthermore, any component of the control housing 120, the control unit 150, or the pump 100 may be made of any or a combination of metals and polymers or any other materials used or known in the relevant fields.

[0038] refer to Figure 1 , Figure 2 The control unit 150 includes a power button 160 that allows operation of the pump 100. The control unit 150 includes a plurality of light-emitting units L1, L2, L3 (alternatively, LEDs (light-emitting diodes) L1, L2, L3) disposed on the control unit 150. This disclosure shows three light-emitting units L1, L2, L3 on the control unit 150; however, in practical implementations of this disclosure, any number of light-emitting units L1, L2, L3 may be used depending on the needs of the pump 100 or any other factor. These plurality of light-emitting units L1, L2, L3 indicate one or more operating parameters of the pump 100 (e.g., battery status, power mode, or timer mode).

[0039] In some implementations, the power button 160 can be used to "turn off" or "turn on" the pump 100. Furthermore, any mode of the pump 100, such as power mode or timer mode, can be interrupted or stopped by pressing the power button 160. Additionally, the pump 100 may have safety features to continuously monitor the different modes of the pump 100 and associated operating parameters. In a non-limiting example, a low voltage level in the pump 100's battery can initially provide an alarm to the user, and then automatically stop the power mode or timer mode without any user action.

[0040] Figure 3A control unit 150 with a control button 170 and the plurality of light-emitting units L1, L2 is shown. The control button 170 operates the pump 100 based on user actions. Furthermore, the plurality of light-emitting units L1, L2, L3 are integrated with the control unit 150. The plurality of light-emitting units L1, L2, L3 indicate one or more operating parameters of the pump 100. This implementation allows the control unit 150 to be used only with the control button 170, without any power button 160, as shown in this figure. This arrangement of the control unit 150 with only the control button 170 and the light-emitting units L1, L2, L3 further allows for ease of operation and aesthetic benefits in the application of the control unit 150. In this case, different operations such as "on," "off," and mode changes can be performed through different user actions of the control button 170, without the need for multiple buttons on the control unit 150. In some embodiments, the plurality of operating modes include a power on / off mode of the pump 100. This allows the control button 170 to be used to activate the power on / off mode of the pump 100.

[0041] In some embodiments, the plurality of light-emitting units L1, L2, L3 are LEDs (light-emitting diodes); however, any other light-emitting device can be readily implemented using this disclosure. From an application and efficiency perspective, the use of LEDs allows for easy and user-friendly visual indication of operating parameters, along with other benefits of LEDs.

[0042] In some implementations, the number of LEDs L1, L2, L3 is at least three. The number, type, size, and placement of LEDs L1, L2, L3 may depend primarily on the mode, sub-mode, and the number of operating parameters associated with pump 100. The number of LEDs L1, L2, L3 can provide indications of status (e.g., activity, error, etc.), stage, or any other value related to one or more operating parameters.

[0043] The control unit 150 includes a control button 170 actuated based on user actions. User actions can be short presses, long presses, or any other interaction between the control button 170 and the user (e.g., a double press with a short interruption). The control button 170 allows the user to switch between multiple operating modes of the pump 100 based on different user actions. Furthermore, the plurality of light-emitting units L1, L2, L3 indicate the switching between the multiple operating modes of the pump 100 through color changes corresponding to the multiple operating modes (or one or more operating parameters) of the pump 100. Therefore, this disclosure provides a control unit 150 that allows switching between different operating modes of the pump 100 using a single button (i.e., control button 170), as shown later in different embodiments.

[0044] In some embodiments, the control unit 150 may be adapted to interact with a user's portable device (e.g., a smartphone, tablet, etc.) to transmit any messages / notifications / alarms to the user's portable device in real time or according to user-set characteristic preferences regarding mode changes, operating parameters, or time periods. The control unit 150 may also be implemented at least partially on the portable device, allowing the activation and / or switching of at least partially different operating modes on the portable device. Alternatively or additionally, at least some operating parameters may be visible on the user's portable device. This arrangement is for illustrative purposes only, and this disclosure can be readily used with any wireless device to transmit messages / notifications / alarms, as known or used in the art.

[0045] refer to Figures 4A to 4D The control unit 150 is shown as a battery mode among multiple operating modes for the pump 100. The control unit 150 includes a series of three LEDs L1, L2, L3 to indicate the battery status (here, a green "G") during battery mode. As shown, different numbers of LEDs L1, L2, L3 being lit or "on" indicate different battery states in the battery mode. Figure 4A Only LED L1 is shown as "on" with flashing, indicating a battery status of 0% to 10%, or nearly empty. Additionally, LED L1 without any flashing indicates a battery status of 11% to 33%. Figure 4B As shown. Furthermore, when LEDs L1 and L2 are lit together (or "on"), the battery status ranges from 34% to 66%, as indicated. Figure 4C As shown. Furthermore, the illumination of all LEDs L1, L2, and L3 indicates the battery status as 67% to 100%, as shown. Figure 4D As shown. This disclosure uses green "G" to indicate the LEDs L1, L2, L3 of the control unit 150 to indicate the battery status; however, any other color can be used for this indication without any limitation. In some embodiments, the battery status can be indicated throughout the entire operating cycle of the pump 100, while the battery status can be activated when the pump 100 is switched to "on," for example, by using the power button 160. Additionally, or alternatively, after the pump 100 is "turned on" using the power button 160, the battery status can be activated by applying the control button 170.

[0046] refer to Figures 5A to 5C and Figures 6A to 6CThe control unit 150 is shown for use in a first mode and a second mode, respectively. Exemplary examples of this disclosure show a first mode and a second mode, which are respectively a power supply mode and a timer mode for the pump 100. Hereinafter, the first mode and the second mode are interchangeably referred to as "power supply mode" and "timer mode." It will be apparent to those skilled in the art that the different modes of this disclosure can be any mode, such as a power supply mode, a timer mode, or a battery state, etc.

[0047] In some embodiments, the different user actions of this disclosure include a first user action and a second user action. When control button 170 is actuated by the first user action, a first mode (or power mode) is activated, and when control button 170 is actuated by the second user action, a second mode (or timer mode) is activated. This allows easy use of control button 170 to switch between the first and second modes using a single button, i.e., control button 170. The first user action may be pressing control button 170 for a first time period (e.g., pressing for 5 seconds), and the second user action may be pressing control button 170 for a second time period (e.g., pressing for 3 seconds). This allows different modes to be selected on the control panel by different user actions, i.e., by utilizing the first and second user actions of control button 170. In some embodiments, pressing control button 170 below a threshold time period may result in the first user action, and pressing control button 170 above the threshold time period may result in the second user action. In a non-limiting example, the threshold time period may be 4 seconds, or any other value according to user preference. This disclosure refers only to exemplary types and values ​​of the first user action, the second user action, the first time period, and the second time period for purposes of reference and explanation. However, different types and values ​​of such user actions and time periods have been contemplated, and all such variations are entirely within the scope of this disclosure.

[0048] In some embodiments, the control button 170 may be integrated with a light-emitting element (not shown), such that the control button 170 changes color based on multiple operating modes. Thus, the control button 170 may additionally or alternatively serve as an indicator of changing between a first mode and a second mode based on a corresponding first or second user action using the control button 170. This disclosure refers to battery mode, first mode / power mode, and second mode / timer mode for illustrative purposes; however, the pump 100 may have any number of modes to suit application needs.

[0049] like Figures 5A to 5CThe power mode (or first mode) shown is activated by pressing control button 170 for a first time period (5 seconds in some embodiments). During implementation, pressing control button 170 initially activates the mode light for the power mode (i.e., the blue "B" mode light). Then, pressing control button 170 again within 5 seconds sets the mode as follows: Figures 5A to 5C Any sub-mode (or level) of the power mode shown. Figure 5A LED L1 is shown flashing a blue "B" light to indicate the first power level of the power mode. Similarly, Figure 5B , Figure 5C LEDs L1, L2 and L1, L2, L3 are shown flashing to indicate the second and third power levels of the power mode.

[0050] Activation is achieved by pressing the control button 170 for a second time period (3 seconds in some embodiments). Figures 6A to 6C The timer mode (or second mode) is shown. During implementation, pressing control button 170 for the second time period activates the mode light (i.e., the green "G") for the timer mode. This begins the green "G" and blue "B" lights on LED L1 to flash in the middle, indicating the first timer (e.g., 5 minutes). Figure 6A As shown. Then, if control button 170 is not pressed within 5 seconds, the timer starts; otherwise, pressing control button 170 within 5 seconds allows setting the timer mode, such as... Figure 6B , Figure 6C As shown. Figure 6B LEDs L1 and L2 are shown flashing green "G" to blue "B" to indicate a second timer (e.g., 10 minutes). Similarly, Figure 6C LEDs L1, L2, and L3 are shown flashing to indicate a third timer (e.g., 15 minutes) in the timer mode. In one embodiment, pump 100 can automatically switch "off" after the timer mode ends, for example, for efficiency and safety reasons. This embodiment mentions different exemplary values ​​of 5, 10, and 15 minutes for the first, second, and third timers, respectively; however, the timer mode can have any value for such timers without any limitation.

[0051] In some embodiments, when pump 100 switches between a first mode (e.g., power mode) and a second mode (e.g., timer mode), the plurality of light-emitting units L1, L2, L3 switch between a first color and a second color. Therefore, the color change of the plurality of light-emitting units L1, L2, L3 serves as a simple and easy visual indicator to verify the change between the first and second modes. Furthermore, the first color and the second color are blue (B) and green (G), respectively. The selection of the first and second colors can be based on user preference, ease of distinction, ambient light around pump 100, or any implementation factor. Additionally or alternatively, control unit 150 may include one or more audio indicators, alarms, or signals to indicate the change between the first and second modes. The audio indicators, alarms, or signals may be integrated with the operation of control button 170, for example, to indicate the change between the first and second modes of pump 100.

[0052] In some embodiments, the plurality of operating modes of pump 100 includes a battery mode, a first mode having a first operating parameter, and a second mode having a second operating parameter. More specifically, the first mode is a power supply mode having a plurality of power levels (i.e., first, second, and third power levels) as the first operating parameter, respectively as follows: Figures 5A to 5C As shown. The second mode is a timer mode with first, second, and third time periods as the second operation parameters, as shown respectively. Figures 6A to 6C As shown.

[0053] Figure 7 The diagram illustrates various states of LEDs L1, L2, and L3 of the control unit 150 during a timer mode implementation of the pump 100 according to one embodiment of the invention. During the timer mode, LEDs L1, L2, and L3 periodically indicate the battery status after a fixed time period T, and then once the lights from LED L3 to LED L1 (here, blue "B") are activated. As shown, the control panel 150 includes LEDs L1, L2, and L3 that are green "G" at the beginning and end of the fixed time period T. The fixed time period T can be any time period preset by the user of the pump 100, such as five seconds. This feature of LEDs L1, L2, and L3, as shown in this figure, allows the user to visually inspect the operating status of LEDs L1, L2, and L3 regarding both blue "B" and green "G" after the fixed time period T, among other implementation benefits.

[0054] In some implementations, the plurality of LEDs L1, L2, L3 can selectively indicate the battery status of pump 100 during a first mode and a second mode. This allows for dynamic indication of the battery status of pump 100 to the user during both the first and second modes.

[0055] This disclosure allows the control unit 150 to be used with any pump 100. The control unit 150 provides multiple uses for the control button 170 to facilitate switching between different modes of the pump 100. Furthermore, the control unit 150 uses LEDs L1, L2, and L3 to indicate the dynamic state, level, or condition of different operating parameters of different modes during switching between different modes by changing the color of one or more of the LEDs L1, L2, and L3. Therefore, the control unit 150 of this disclosure allows for multi-mode selection using a single button (i.e., control button 170), making the control unit 150 convenient and user-friendly.

[0056] Preferred embodiments and examples of the invention have been disclosed in the accompanying drawings and description, and although specific terminology has been used, it is used in a general and descriptive sense only and not to limit the scope of the invention as set forth in the appended claims.
