Description

Technical Field

[0001] This invention relates to the field of vacuum cleaner technology, and more particularly to a magnetically fixed headlamp accessory mounting structure for vacuum cleaners. Background Technology

[0002] A vacuum cleaner is a cleaning device that uses a high-speed rotating motor to generate negative pressure, thereby sucking in air and separating and collecting dust, debris, and other impurities. Handheld vacuum cleaners can be connected to a floor brush via a conductive tube, allowing the operator to clean floors while standing, enabling scene-specific cleaning.

[0003] A vacuum cleaner headlamp is a lighting device installed on the vacuum cleaner head or handle. It illuminates dark areas such as under furniture and beds during cleaning, improving cleaning efficiency by enhancing visibility. Currently, the fixed installation location of vacuum cleaner headlamps cannot meet the lighting needs of users in different cleaning scenarios. Summary of the Invention

[0004] The purpose of this invention is to provide a magnetically fixed headlamp accessory mounting structure for vacuum cleaners, so as to solve the problem that the fixed position of the headlamp on the existing vacuum cleaner cannot meet the lighting needs of different cleaning scenarios.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a magnetically fixed headlamp accessory mounting structure for a vacuum cleaner, comprising:

[0006] The headlamp includes a headlamp base, a headlamp PCBA, probe contact pieces, a magnet, and a top cover. The headlamp PCBA is fixedly mounted on the headlamp base and has LED beads. The headlamp base has notches corresponding to the positions of the LED beads. The probe contact pieces are fixedly mounted on the bottom surface of the headlamp base and are connected to the headlamp PCBA via wires. The magnet is fixedly mounted on the bottom surface of the headlamp base. The top cover is fixedly mounted on the headlamp base and has a headlamp cover that snaps into the notch.

[0007] The probe connector includes a probe base, a spring pin, and an iron block. The probe base is fixedly mounted on the vacuum cleaner module, the spring pin is fixedly mounted on the probe base, and the iron block is fixedly mounted on the probe base. When the iron block is attracted to the magnet of the headlamp, the spring pin contacts the probe contact piece.

[0008] As a further description of the above technical solution:

[0009] The vacuum cleaner module has a positioning groove, and the probe connector is fixedly installed on the bottom surface of the positioning groove.

[0010] As a further description of the above technical solution:

[0011] The vacuum cleaner module can be either the vacuum cleaner main unit or the floor brush.

[0012] As a further description of the above technical solution:

[0013] A first resistor is connected in series in the power supply circuit of the probe connector at the vacuum cleaner main unit, and a second resistor is connected in series in the power supply circuit of the probe connector at the floor brush. The resistance values ​​of the first resistor and the second resistor are different.

[0014] As a further description of the above technical solution:

[0015] The top cover has raised ribs, and the headlamp holder has a slot with a matching shape on top.

[0016] As a further description of the above technical solution:

[0017] A pressure plate is also provided on the bottom surface of the top cover, and the pressure plate contacts the back of the magnet.

[0018] As a further description of the above technical solution:

[0019] The bottom surface of the headlamp holder has a groove, and the magnet is fixedly installed on the bottom surface of the groove.

[0020] As a further description of the above technical solution:

[0021] The end face of the headlamp cover protrudes from the side wall of the headlamp holder 11.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. In this invention, the headlamp is connected to the probe connector on the vacuum cleaner by magnetic fixation. The vacuum cleaner main unit or the floor brush is equipped with a probe connector, so that the headlamp can be used as an independent accessory on the handheld vacuum cleaner main unit and the floor brush, thus meeting the user's lighting needs in different cleaning scenarios at low cost.

[0024] 2. In this invention, the headlamp adopts a dual-color design, with the headlamp base and the top cover being different colors, so as to quickly identify the direction of the headlamp and make it easy to accurately install the headlamp into the positioning slot.

[0025] 3. In this invention, the distance between the headlamp and the user varies depending on whether the headlamp is installed on the handheld vacuum cleaner main unit or the floor brush. Therefore, in order to enable the headlamp to automatically adjust its brightness according to the different installation positions, a specific resistor is connected in series in the power supply circuit of the probe connectors at different positions to distinguish them. The lamp detects the difference in contact voltage through an analog-to-digital converter, accurately identifies the connection position, determines the position, and calls the preset brightness program.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0038] Example 1

[0039] Please see Figure 1-7 This invention provides a technical solution: a magnetically attached headlamp accessory mounting structure for a vacuum cleaner, comprising:

[0040] The headlamp 1 includes a headlamp base 11, a headlamp PCBA 12, a probe contact piece 13, a magnet 14, and a top cover 15. The headlamp PCBA 12 is fixedly mounted on the headlamp base 11 and is equipped with LED beads 121. The LED beads 121 on the headlamp PCBA 12 emit light to provide illumination. The headlamp base 11 is provided with notches 111 corresponding to the positions of the LED beads 121. The probe contact piece 13 is fixedly mounted on the bottom surface of the headlamp base 11 and is connected to the headlamp PCBA 12 via wires. The magnet 14 is fixedly mounted on the bottom surface of the headlamp base 11. The top cover 15 is fixedly mounted on the headlamp base 11 and is provided with a headlamp cover 151. The headlamp cover 151 is snapped into the notch 111. The headlamp cover 151 is made of transparent material and its end face protrudes from the side wall of the headlamp base 11, effectively marking the lighting direction of the headlamp 1 and facilitating blind operation of the headlamp 1 installation in poor lighting conditions.

[0041] The probe connector 2 includes a probe base 21, a spring pin 22, and an iron block 23. The probe base 21 is fixedly mounted on the vacuum cleaner module, the spring pin 22 is fixedly mounted on the probe base 21, and the iron block 23 is fixedly mounted on the probe base 21. When the iron block 23 is attracted to the magnet 14 of the headlamp 1, the spring pin 22 contacts the probe contact piece 13.

[0042] The vacuum cleaner module is either the vacuum cleaner main unit 3 or the floor brush 4, and the vacuum cleaner module is provided with a positioning groove 5, and the probe connector 2 is fixedly installed on the bottom surface of the positioning groove 5.

[0043] The positioning groove 5 is formed by a recessed groove or baffle on the housing of the vacuum cleaner module, so as to realize the contour positioning of the headlamp 1.

[0044] Working principle: The headlamp 1 is connected to the probe connector 2 on the vacuum cleaner by magnetic attachment. The male POGO-PIN (i.e., spring pin 22) on the probe connector 2 contacts the POGO-PIN contact piece (i.e., probe contact piece 13) on the bottom surface of the headlamp 1. The vacuum cleaner main unit 3 or the floor brush 4 are both equipped with probe connector 2, so that the headlamp 1 can be used as an independent accessory on the handheld vacuum cleaner main unit 3 and the floor brush 4, thus meeting the lighting needs of users in different cleaning scenarios at low cost.

[0045] The headlamp 1 adopts a dual-color design, with the headlamp base 11 and the top cover 15 being different colors, so as to quickly identify the direction of the headlamp 1 and make it easy to accurately install the headlamp 1 into the positioning slot 5.

[0046] Example 2

[0047] Based on the above embodiments, this embodiment further improves upon the following technical solution: a first resistor is connected in series in the power supply circuit of the probe connector 2 at the vacuum cleaner main unit 3, and a second resistor is connected in series in the power supply circuit of the probe connector 2 at the floor brush 4. The resistance values ​​of the first resistor and the second resistor are different.

[0048] Whether the headlamp 1 is mounted on the handheld vacuum cleaner main unit 3 or the floor brush 4 results in different distances between the headlamp 1 and the user. Therefore, in order to enable the headlamp 1 to automatically adjust its brightness according to different installation positions, a specific resistor is connected in series in the power supply circuit of the probe connector 2 at different positions to distinguish them.

[0049] When headlamp 1 is magnetically connected, the lamp uses an analog-to-digital converter to detect the voltage difference at the contacts, accurately identifying the connection position. This allows the lamp to determine the location and activate the preset brightness program. This ensures that the brightness of headlamp 1 on the vacuum cleaner main unit 3 is lower than the brightness of headlamp 1 on the floor brush 4, preventing excessive brightness.

[0050] Example 3

[0051] This embodiment further improves upon the above embodiment by providing the following technical solution: a raised rib 152 is provided on the bottom surface of the upper cover 15, and a slot 112 with a matching shape to the raised rib 152 is provided on the top of the headlamp holder 11. The upper cover 15 is inserted into the slot 112 on the top of the headlamp holder 11 via the raised rib 152, and then fixed by ultrasonic waves, effectively improving the sealing performance of the headlamp 1.

[0052] Similarly, the bottom of the headlamp cover 151 is provided with a protruding structure that connects to the bottom surface of the notch 111.

[0053] Example 4

[0054] Based on the above embodiments, the following improved technical solutions are made in this embodiment: a pressure plate 153 is also provided on the bottom surface of the upper cover 15, and the pressure plate 153 contacts the back of the magnet 14.

[0055] The upper cover 15 presses the positioning magnet 14 through the pressure plate 153 to ensure the adsorption effect between the headlamp 1 and the probe connector 2.

[0056] Example 5

[0057] Based on the above embodiments, this embodiment further improves upon the following technical solution: a groove 113 is provided on the bottom surface of the headlamp holder 11, and a magnet 14 is fixedly installed on the bottom surface of the groove 113.

[0058] The headlamp holder 11 has a recessed design via groove 113, which effectively protects the magnet 14 and the probe contact piece 13. Correspondingly, the probe seat of the probe connector 2 protrudes from the bottom surface of the positioning groove 5 to facilitate magnetic attraction and contact of the spring pin 22 with the probe contact piece 13.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
