Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to an electric soap maker. Background Technology

[0002] Solid soap is widely used in daily life due to its affordability and strong cleaning power. However, traditional solid soap has many inconveniences when used: it easily leaves stains and watermarks on the surface, breeding bacteria; it softens in water and easily produces sticky soap sludge, resulting in waste and contaminating the soap dish; and it is not hygienic when used by multiple people. To improve these problems, electric soap grinders that can grind solid soap into powder have appeared on the market.

[0003] Existing electric soap makers typically use a motor to drive blades to scrape soap bars and extract powder. However, these devices generally suffer from the following technical drawbacks: First, most of these devices employ simple open-loop timing control, where the motor runs for a fixed period after a sensor triggers the circuit. However, due to factors such as motor load, battery voltage fluctuations, changes in soap hardness, and blade wear, the actual number of scraping revolutions and the amount of soap powder dispensed within the same running time are inconsistent, leading to a lack of consistent user experience. Second, as the soap bar is continuously consumed, the contact pressure between its bottom surface and the rotating scraper gradually decreases, even developing gaps, resulting in a sharp reduction in soap powder dispensed until it can no longer dispense any, causing soap residue and waste. Third, most products require an external power cord, limiting their installation location in damp environments such as bathrooms and kitchens, posing safety hazards and lacking flexibility. Furthermore, the scraping mechanism of some devices is inefficient, prone to clogging due to poor powder discharge, and lacks clear operating status indicators, making it impossible for users to intuitively understand whether the equipment is ready or malfunctioning. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an electric soap machine, which aims to solve the problems in the background art.

[0005] To achieve the aforementioned objectives of this utility model, the first aspect of this utility model provides an electric soap maker, comprising: The shell has a cavity for holding the soap block and a powder outlet communicating with the cavity; A blade assembly is rotatably disposed within the chamber, located below the soap block, and is used to scrape the bottom of the soap block to produce soap powder; A drive mechanism, disposed within the housing, includes a motor and a transmission assembly driven by the motor, the transmission assembly being connected to the cutter head assembly to drive its rotation; A sensor, disposed on the housing, is used to sense user operation signals; A control unit, electrically connected to the sensor and the drive mechanism, controls the operation of the drive mechanism in response to a signal from the sensor; and The position detection module includes a magnet disposed on the cutter head assembly and a Hall sensor disposed on the housing at a position corresponding to the magnet. The Hall sensor is electrically connected to the control unit and is used to detect the number of rotations or position of the cutter head assembly. The control unit is configured to control the motor to rotate the cutter head assembly a predetermined number of revolutions or angles during a single trigger operation, based on the feedback signal from the Hall sensor.

[0006] Optionally, the blade assembly includes a disc body and at least two scrapers disposed on the disc body, the at least two scrapers being arranged in a cross shape.

[0007] Optionally, the disc body is provided with a powder outlet channel, and the powder outlet channel is correspondingly provided with the scraper, so that the soap powder generated by scraping can move outward along the powder outlet channel.

[0008] Optionally, the cavity is provided with an inner support, and the soap block is placed on the inner support; The electric soap maker also includes an elastic push rod assembly, which acts on the upper end of the soap block, causing its bottom to continuously abut against the blade assembly.

[0009] Optionally, the elastic push rod assembly includes a pressure plate that can move up and down and slides inside the housing, and a spring that provides downward pressure to the pressure plate. A limiting screw for limiting the pressure plate is fixedly connected to the housing.

[0010] Optionally, it also includes a working status indicator light, which is electrically connected to the control unit and is used to indicate the standby, running, or fault status of the device.

[0011] Optionally, the transmission assembly includes a drive gear disposed on the motor output shaft and a driven gear disposed coaxially with the cutter head assembly, wherein the drive gear meshes with the driven gear.

[0012] Optionally, the housing is provided with a main power switch for controlling the power supply to the electric soap maker.

[0013] Optionally, the power source is a built-in battery.

[0014] Optionally, it also includes a wall mount bracket, on which the housing is detachably mounted.

[0015] The beneficial effects of this utility model are: 1. This utility model of an electric soap maker uses a position detection module composed of magnets and Hall effect sensors to detect the number of rotations or angles of the blade assembly in real time, and feeds the signal back to the control unit, forming a closed-loop control system. This allows the control unit to precisely control the motor's rotation stroke after a single trigger, completely overcoming the problem of unstable soap powder output caused by load changes and voltage fluctuations. The amount of soap powder obtained by the user is highly consistent each time, and different powder output modes can be preset through the program to meet personalized needs in different scenarios.

[0016] 2. The electric soap maker of this invention, through the cooperation of the elastic push rod assembly and the inner support, ensures that the bottom of the soap block is always tightly pressed against the rotating blade assembly by the continuous downward pressure provided by the spring, regardless of how much soap block is consumed. This design fundamentally eliminates the phenomenon of powder reduction caused by insufficient contact pressure, allowing the soap block to be almost completely utilized, significantly reducing waste and improving the product's economy.

[0017] 3. This utility model of an electric soap maker utilizes a blade assembly with multiple scrapers arranged in a cross pattern, combined with radially arranged powder outlet channels on the blade body, forming a highly efficient and coordinated working system. The cross-shaped scraper layout ensures uniform scraping force, higher efficiency, and finer powder production; it also guarantees a smooth and reliable powder outlet process.

[0018] 4. This utility model of an electric soap maker, powered by a built-in rechargeable battery and equipped with a mechanical main power switch, completely eliminates the reliance on a fixed power outlet. This not only eliminates the safety hazards of using wired power in humid environments but also achieves true wireless portability. Users can freely place it on a countertop or hang it via a wall-mounted bracket, easily adapting to various decorating styles and spatial layouts. Attached Figure Description

[0021] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Reference Figures 1-8 An embodiment of the present invention provides an electric soap maker, comprising: The shell 1 has a cavity for accommodating the soap block 15 and a powder outlet 11 communicating with the cavity; The blade assembly 2 is rotatably disposed in the chamber below the soap block 15 and is used to scrape the bottom of the soap block 15 to produce soap powder; The drive mechanism is disposed inside the housing 1 and includes a motor 31 and a transmission component 32 driven by the motor 31. The transmission component 32 is connected to the cutter head assembly 2 to drive it to rotate. Sensor 4 is disposed on the housing 1 and is used to sense user operation signals; The control unit, electrically connected to the sensor 4 and the drive mechanism, controls the operation of the drive mechanism in response to signals from the sensor 4; and The position detection module includes a magnet 61 disposed on the cutter head assembly 2 and a Hall sensor 62 disposed on the housing 1 at a position corresponding to the magnet 61. The Hall sensor 62 is electrically connected to the control unit and is used to detect the number of rotations or position of the cutter head assembly 2. The control unit is configured to control the motor 31 to rotate the cutter head assembly 2 a predetermined number of revolutions or angles during a single trigger operation, based on the feedback signal from the Hall sensor 62.

[0025] Understandably, this electric soap maker mainly includes a housing 1, a blade assembly 2, a drive mechanism, a sensor 4, a control unit (not shown separately in the figure, but usually integrated on a circuit board), and a position detection module. The housing 1 has an internal cavity for housing the various functional components and accommodating the soap block 15. A powder outlet 11 is located at the bottom or side of the housing 1, through which the produced soap powder is discharged. Under the command of the control unit, the drive mechanism drives the blade assembly 2 to rotate, and the blade assembly 2 scrapes the bottom of the soap block 15 using its scraper 22. The sensor 4 receives a trigger signal from the user (such as a hand approaching). The control unit responds to this signal and, based on feedback from the position detection module, precisely controls the drive mechanism to run a predetermined stroke, thereby outputting a fixed amount of soap powder.

[0026] The drive mechanism includes a motor 31 and a transmission assembly 32. The motor 31 is fixed inside the housing 1, and its power is transmitted to the cutter head assembly 2 through the transmission assembly 32. Sensors 4 (such as infrared sensors or capacitive sensors) are installed on the front or top of the housing 1 in a location easily accessible for user operation. The control unit is typically a microcontroller (MCU), integrated on the main circuit board, and electrically connected to the sensors 4 and the motor 31, respectively.

[0027] It also includes a magnet 61 fixedly mounted on the rotating component of the cutter head assembly 2, and a Hall sensor 62 fixedly mounted inside the housing 1 at a position corresponding to the rotation trajectory of the magnet 61. The Hall sensor 62 is connected to the control unit on the circuit board. When the cutter head assembly 2 rotates, the magnet 61 rotates accordingly, and the Hall sensor 62 generates a pulse signal each time it passes the Hall sensor 62. The control unit can accurately determine the actual number of rotations or angle of the cutter head assembly 2 by counting the number of these pulse signals. Through the closed-loop feedback system formed by the position detection module, the control unit can monitor the motion state of the cutter head assembly 2 in real time and accurately. This completely changes the problem of uncontrollable powder output caused by motor 31 stalling, slippage, or voltage fluctuations in the traditional open-loop control method. The control unit can, according to a preset program (such as a single trigger corresponding to 3 pulse signals, i.e., 1.5 rotations), continue to run the motor 31 until the predetermined number of pulses is received after receiving the sensing signal. It not only achieves a high degree of consistency and customizability in the amount of powder dispensed per batch, improving the user experience, but also effectively prevents motor 31 from being overloaded and damaged due to the blade jamming, thus improving the reliability and service life of the electric soap maker.

[0028] In some embodiments, the blade assembly 2 includes a disc body 21 and at least two scrapers 22 disposed on the disc body 21, the at least two scrapers 22 being arranged in a cross shape.

[0029] Understandably, the blade assembly 2 specifically includes a circular disc 21, on the upper surface of which at least two scrapers 22 are fixedly mounted. Preferably, the four scrapers 22 are arranged perpendicularly in pairs, forming a cross shape, and fixed to the disc 21. The multiple scrapers 22 arranged in a cross shape can form a continuous and uniform scraping trajectory on the bottom of the soap block during rotation, avoiding intermittent cutting or uneven force caused by a single scraper 22 or an asymmetrical arrangement. This significantly improves the scraping efficiency per rotation and the uniformity of powder output, resulting in finer soap powder. Simultaneously, the symmetrical structure ensures the dynamic balance of the blade assembly 2 during high-speed rotation, reducing vibration and noise, and making operation smoother.

[0030] In some embodiments, the disc body 21 is provided with a powder outlet channel 23, and the powder outlet channel 23 is correspondingly provided with the scraper 22, so that the soap powder generated by scraping can move outward along the powder outlet channel 23.

[0031] Understandably, a powder dispensing channel 23 is formed on the disc body 21. The soap powder scraped off by the scraper 22 will naturally fall into the powder dispensing channel 23. Under the centrifugal force generated by the rotation of the cutter disc assembly 2, the soap powder can travel along the powder dispensing channel 23 and eventually collect at the powder outlet 11.

[0032] In some embodiments, the cavity is provided with an inner support 7, and the soap block 15 is placed on the inner support 7; The electric soap maker also includes a flexible push rod assembly, which acts on the upper end of the soap block 15, causing its bottom to continuously abut against the blade assembly 2. The flexible push rod assembly includes a pressure plate 162 that slides inside the housing 1 and can move up and down, and a spring 161 that provides downward pressure to the pressure plate 162. A limiting screw 163 for limiting the position of the pressure plate 162 is fixedly connected to the housing 1.

[0033] Understandably, an inner support 7, fixed to the housing 1, is installed inside the chamber. Its shape is typically a ring-shaped bracket or a frame with supporting ribs, and the soap block 15 is placed directly on this inner support 7. To achieve automatic feeding of the soap block 15, the electric soap maker also features an elastic push rod assembly. The spring 161, as a constant or near-constant force elastic element, provides a relatively stable and uniform downward pressure, superior to some springs with rapid pressure decay. The limit screw 163 serves a dual protection function: firstly, it prevents the pressure plate 162 from traveling too far under the action of the spring when installing a new soap block, thus preventing damage to components or excessive squeezing of the soap; secondly, it defines a reasonable upper pressure limit, ensuring sufficient contact force without causing excessive rotational resistance of the blade assembly, optimizing system energy consumption and component lifespan. The elastic push rod assembly, through constant downward pressure, ensures that regardless of how much the thickness of the soap block 15 decreases due to consumption, its bottom always remains tightly and stably against the rotating blade assembly 2's scraper 22. This fundamentally solves the problem of reduced or even no powder output caused by the wear and tear of soap block 15 and the gap between the soap block 15 and scraper 22 due to uneven bottom surface. It ensures that the efficiency and powder output of each scraping remain consistent throughout the entire service life of soap block 15. The limit screw 163 prevents the pressure basin from falling off from below.

[0034] In some embodiments, a working status indicator light 9 is also included, which is electrically connected to the control unit and is used to indicate the standby, running or fault status of the device.

[0035] Understandably, a status indicator light 9 (such as a tri-color LED) is installed on the front or in a prominent position of the housing 1, and it is connected to the control unit on the circuit board. By controlling the status indicator light 9 to emit different colors or flashing patterns (for example, solid blue indicates standby, flashing green indicates powder dispensing, and solid red indicates low battery or malfunction), the system can provide users with intuitive and clear feedback on the device's status. This greatly improves the user-friendliness of human-machine interaction, eliminating the need for users to guess whether the machine is ready, working, or experiencing problems, thus enhancing convenience and a sense of security.

[0036] In some embodiments, the transmission assembly 32 includes a drive gear 321 disposed on the output shaft of the motor 31 and a driven gear 322 disposed coaxially with the cutter head assembly 2, wherein the drive gear 321 meshes with the driven gear 322.

[0037] Understandably, the drive gear 321 meshes directly with the driven gear 322. Gear meshing transmission offers advantages such as compact structure, high transmission efficiency, and precise and reliable power transmission.

[0038] Furthermore, the output end of the motor 31 is connected to the drive gear 321 of the transmission assembly 32 via a reducer. The reducer can convert the high-speed, low-torque output of the motor 31 into the lower speed and higher torque required by the cutter head assembly 2. This satisfies the force required for scraping soap while allowing the motor 31 to operate in its high-efficiency range, thus balancing scraping effect and energy economy.

[0039] In some embodiments, the housing 1 is provided with a main power switch 12 for controlling the on / off of the power supply to the electric soap maker. The power source is a built-in storage battery 13.

[0040] Understandably, a mechanical main power switch 12 is provided on the side or bottom of the housing 1 to directly cut off or connect the power input of the entire machine, facilitating safe storage when not in use for extended periods. The power source preferably uses a rechargeable built-in battery 13 (such as a lithium-ion battery), installed in a dedicated battery compartment inside the housing 1, and charged via a charging management circuit on the circuit board (through a USB interface). The mechanical main power switch 12 provides the most direct physical power-off protection, eliminates standby power consumption, and increases safety. Using a built-in battery 13 for power completely eliminates the dependence on a fixed power outlet, achieving true wireless and portable operation.

[0041] In some embodiments, a wall mount bracket 14 is also included, on which the housing 1 is detachably mounted.

[0042] Understandably, it also includes a separate wall-mounted bracket 14. This bracket 14 can be fixed to the wall using screws or other fasteners. The back of the housing 1 has a slot or hook structure that can be matched to allow for detachable mounting of the housing 1 on the wall-mounted bracket 14. Two usage modes are provided: wall-mounted and countertop placement. Wall-mounted installation saves valuable countertop space, making the washbasin surface neater, and the fixed height of the powder outlet 11 facilitates easy access. Simultaneously, the detachable design allows users to easily remove the main unit for charging, refilling soap, or cleaning and maintenance, balancing installation stability with ease of use.

[0043] In this utility model, the motor 31, sensor 4, Hall sensor 62, and working status indicator 9 are all common designs in the field and are common knowledge in the field. Therefore, no specific structural description or corresponding working principle description will be given here.

[0044] In practical application, when a user needs to wash their hands, they extend their hand in front of sensor 4. Sensor 4 detects the signal and sends it to the control unit. The control unit then starts motor 31, which drives the blade assembly 2 to rotate via drive gear 321 and driven gear 322. Magnet 61, fixed to blade assembly 2, passes Hall sensor 62 once per rotation, generating a pulse feedback. The control unit counts these pulses, and when a preset value is reached (e.g., corresponding to 2 rotations), it immediately shuts off motor 31. During this process, the cross-shaped scraper 22 scrapes the bottom of the continuously pressed soap block 15 into powder. The soap powder is discharged from outlet 11 through powder outlet channel 23 under centrifugal force and falls into the user's hand. The working status indicator 9 provides corresponding status prompts throughout the process.

[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
