Description

Technical Field

[0001] This utility model relates to the field of nursing care products technology, and in particular to a modular handheld device. Background Technology

[0002] A razor is a core tool in men's daily grooming routine, helping to easily remove facial hair and maintain a clean and neat appearance. Modern razors are mainly divided into two categories: manual razors and electric razors. Manual razors use sharp blades for precise shaving, and with the help of a lubricating strip to reduce irritation, they are suitable for those who want an extremely smooth shave. Electric razors, on the other hand, use a high-speed motor to drive the foil or rotating head to quickly complete a shave.

[0003] Traditional household shavers, in pursuit of high performance and long battery life, often employ large-capacity batteries and multi-functional designs, resulting in a larger overall size and increased weight. This makes them inconvenient to carry during business trips or daily commutes, and fails to meet the diverse usage needs of shavers in multiple scenarios. Consequently, consumers are forced to purchase multiple shavers with different positioning for different usage scenarios, which increases purchase costs and causes inconvenience in use and management.

[0004] Therefore, it is necessary to provide a modular handheld device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a modular handheld device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: A modular handheld device includes a blade module, a first handle module, and a second handle module. The blade module, the first handle module, and the second handle module are detachably connected to each other. Each of the first and second handle modules contains a power supply unit. The modular handheld device has a first working state and a second working state. When the modular handheld device is in the first working state, the blade module, the first handle module, and the second handle module are connected together, and the blade module is powered through the first and second handle modules. When the modular handheld device is in the second working state, the blade module and the second handle module are connected together, and the blade module is powered through the second handle module.

[0007] As a further embodiment of this utility model, the cutter head module includes a first housing and a cutter head installed at the end of the first housing, wherein a power unit for driving the cutter head is provided inside the first housing.

[0008] As a further embodiment of this utility model, the second handle module includes a third housing, inside which a control unit and a second battery unit are disposed. When the second handle module is connected to the cutter head module, the cutter head module is powered through the second battery unit inside the second handle module.

[0009] As a further embodiment of this utility model, the first handle module includes a second housing, and a first battery unit is disposed inside the second housing. When the cutter head module, the first handle module, and the second handle module are connected together, the cutter head module is powered by the first battery unit inside the first handle module and the second battery unit inside the second handle module.

[0010] As a further embodiment of this utility model, a switch button is provided on the second handle module, and a charging port is provided at the bottom of the second handle module.

[0011] As a further embodiment of this utility model, a connecting component is provided between the blade module, the first handle module, and the second handle module for mutual connection. The connecting component includes a connecting protrusion fixed at one end of the housing, and a slot that fits into the connecting protrusion is provided at the other end of the housing. A spring plate is provided at the slot, and a slot is provided on the side of the connecting protrusion. A round protrusion that fits into the slot is fixed at the end of the spring plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When used at home, the first working state is used, where the shaver head module, first handle module, and second handle module are combined. In this state, the shaver is relatively large, but the first and second handle modules work together to power the shaver head module, resulting in a longer battery life that meets the needs of long-term use and avoids frequent charging. When you need to carry it out, the second working state is used, where the shaver head module and second handle module are combined without the first handle module. This makes the shaver smaller, effectively reducing its overall size and making it easier to fit into a travel bag or carry around. It is convenient to store and carry while maintaining basic battery life. Users can freely switch between "long battery life" and "portable" modes according to their needs, meeting the diverse needs of users in various scenarios. Attached Figure Description

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-5This utility model provides a modular handheld device, including a blade module 1, a first handle module 2, and a second handle module 3. The blade module 1, the first handle module 2, and the second handle module 3 are detachably connected to each other. Each of the first handle module 2 and the second handle module 3 contains a power supply unit. The modular handheld device has a first working state and a second working state. When the modular handheld device is in the first working state, the blade module 1, the first handle module 2, and the second handle module 3 are connected together, and the blade module 1 is powered through the first handle module 2 and the second handle module 3. When the modular handheld device is in the second working state, the blade module 1 and the second handle module 3 are connected together, and the blade module 1 is powered through the second handle module 3. Specifically, the modular handheld device is a shaver, and the shaver has a modular assembly design, consisting of a blade module 1, a first handle module 2, and a second handle module 3. The shaver consists of three modules: a handle module 2 and a second handle module 3. When used at home, the first working state is used, where the shaver head module 1, the first handle module 2, and the second handle module 3 are used together. In this state, the shaver is relatively large, but the first handle module 2 and the second handle module 3 work together to power the shaver head module 1, resulting in a longer battery life that meets the needs of long-term use and avoids frequent charging. When it is necessary to carry the shaver out, the second working state is used, where the shaver head module 1 and the second handle module 3 are used together without the first handle module 2. This makes the shaver smaller, effectively reducing its overall size and making it easier to put into a travel bag or carry around. It is convenient to store and carry while maintaining basic battery life. Users can freely switch between "long battery life" and "portable" modes according to their needs, meeting the diverse needs of users in multiple scenarios.

[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the blade module 1 includes a first housing 101 and a blade 102 installed at the end of the first housing 101. A power unit for driving the blade 102 is provided inside the first housing 101. The power unit includes a drive motor and a transmission structure. The specific structure and working principle of the shaver power unit are existing technologies that have been disclosed and will not be described in detail in this application. The battery unit supplies electrical energy to the power unit, which drives the blade 102 to work.

[0025] Further as Figure 1 and Figure 3As shown, it is worth noting that the second handle module 3 includes a third housing 301, which houses a control unit and a second battery unit. When the second handle module 3 is connected to the blade head module 1, the blade head module 1 is powered by the second battery unit within the second handle module 3. When it needs to be carried around, a second working state is used, where the blade head module 1 and the second handle module 3 are used together without the first handle module 2. In this state, the second battery unit within the second handle module 3 is electrically connected to the power unit within the blade head module 1, and the blade head module 1 is powered by the second battery unit within the second handle module 3. This makes the entire shaver smaller, effectively reducing its overall size, making it easier to put into a travel bag or carry around, and retaining basic battery life while being convenient to store and carry.

[0026] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the first handle module 2 includes a second housing 201, and a first battery unit is disposed inside the second housing 201. When the shaver head module 1, the first handle module 2, and the second handle module 3 are connected together, the shaver head module 1 is powered by the first battery unit in the first handle module 2 and the second battery unit in the second handle module 3. When used at home, the first working state is used, that is, the shaver head module 1, the first handle module 2, and the second handle module 3 are used together. At this time, the entire shaver is larger in size, but the shaver head module 1 is powered by the first battery unit in the first handle module 2 and the second battery unit in the second handle module 3, resulting in a longer battery life, meeting the needs of long-term use and avoiding frequent charging.

[0027] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the second handle module 3 is equipped with a switch button 4, and the bottom of the second handle module 3 is equipped with a charging port 6. The battery units in the first handle module 2 and the second handle module 3 are equipped with conductive sheets for connecting current. The conductive sheets are usually stamped from a metal material with good elasticity (such as phosphor bronze or nickel-plated copper alloy). Their structure includes a fixed end, an elastic bending part, and a contact end. When the handle module is installed, the conductive sheets on the battery unit are pressed and contacted. Through the elastic structure of the conductive sheets, a tight physical contact is formed with the battery electrodes under mechanical pressure. This direct metal-to-metal contact provides a path for electron flow. The conductive sheets are pressed and connected to the power supply to power the cutter head module 1. The specific structure and working principle of the conductive sheets for connecting current are already disclosed in the prior art and will not be repeated in this application.

[0028] Further as Figure 5As shown, it is worth noting that a connecting component 5 is provided between the blade module 1, the first handle module 2, and the second handle module 3 for interconnection. The connecting component 5 includes a connecting protrusion 502 fixed at one end of the housing, and a slot 501 that mates with the connecting protrusion 502 at the other end of the housing. A spring plate 505 is provided at the slot 501, and a slot 504 is provided on the side of the connecting protrusion 502. A round protrusion 503 that mates with the slot 504 is fixed at the end of the spring plate 505. When the blade module 1, the first handle module 2, and the second handle module 3 are connected, a connecting component 5 is provided. When the handle modules 3 are connected to each other, the connecting protrusion 502 at one end of one housing is inserted into the slot 501 at the port of the other housing. Since the spring plate 505 can be elastically deformed to a certain extent, the round protrusion 503 automatically engages in the slot 504 on the side of the connecting protrusion 502, thereby easily locking the two housings together and completing the connection between the cutter head module 1, the first handle module 2 and the second handle module 3. When it is necessary to disassemble, the round protrusion 503 is disengaged from the slot 504 by directly pulling the housing, thereby releasing the connection of the housing and facilitating disassembly.

[0029] This solution has the following working process: When used at home, the first working state is used, that is, the blade head module 1, the first handle module 2, and the second handle module 3 are used together. At this time, the entire shaver is relatively large, but the first battery unit in the first handle module 2 and the second battery unit in the second handle module 3 jointly power the blade head module 1, resulting in a relatively long battery life. When it is necessary to carry it out, the second working state is used, that is, the blade head module 1 and the second handle module 3 are used together. At this time, the second battery unit in the second handle module 3 is electrically connected to the power unit in the blade head module 1, and the blade head module 1 is powered through the second battery unit in the second handle module 3, making the entire shaver smaller and easier to put into a travel bag or carry with you.
