Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a vacuum cleaner with easily replaceable batteries. Background Technology

[0002] Vacuum cleaners use a high-speed motor to drive a turbine fan to generate powerful suction. Combined with a filtration system and a dust collection system, they can quickly collect dust and impurities attached to the home. Portable vacuum cleaners for home use have a compact design and are easy to store, making them extremely convenient household items. However, most portable vacuum cleaners use built-in power supplies that are not easy to disassemble. They also require a charging cable to be plugged in, which is not suitable for scenarios that require continuous use. In addition, replacing the battery requires disassembling the vacuum cleaner, which affects its practicality.

[0003] To address the above issues, Chinese Patent Publication No. CN214180285U proposes a handheld vacuum cleaner with a detachable battery, comprising a handheld vacuum cleaner body and a battery. The handheld vacuum cleaner body has a battery mounting position, and the battery is detachably mounted on the battery mounting position. The battery has a U-shaped mounting groove, and the battery mounting position has a U-shaped mounting block that matches the U-shaped mounting groove. During installation, the battery is installed by the cooperation of the U-shaped mounting block and the U-shaped mounting groove.

[0004] The aforementioned utility model uses an insertable detachable structure to connect the battery and the vacuum cleaner body. When the elastic buckle is inserted into the buckle groove, the elastic buckle button pops up. When the battery needs to be removed, pressing the elastic buckle button engages the battery to achieve quick battery removal. However, the elastic buckle button is located independently on the battery casing, and the battery is prone to accidental dislodgement during use. At the same time, the battery socket needs to be connected to the inside of the vacuum cleaner body to achieve a power supply effect. If the connection position is misaligned, it can easily lead to poor contact due to loose connection, thus affecting the working stability of the vacuum cleaner. Therefore, we propose a vacuum cleaner with an easy-to-replace battery. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a vacuum cleaner with an easily replaceable battery, comprising a vacuum cleaner body, a docking compartment on the vacuum cleaner body, a battery housing slidably connected to the docking compartment, an unlocking button elastically supported on the battery housing, a built-in battery slidably connected in the battery housing, a protective mechanism on the battery housing to prevent accidental activation of the unlocking button, and a support mechanism elastically supporting the built-in battery between the docking compartment and the battery housing.

[0006] In some embodiments, the protective mechanism includes a mounting groove formed on the battery casing, a stepped ring fitted onto the mounting groove, and a sealing cover fitted onto the stepped ring, the sealing cover being an incomplete arc structure.

[0007] In some embodiments, spherical grooves providing rotational damping are symmetrically formed on the inner wall of the stepped ring. Spherical steel balls are connected in the spherical grooves. The spherical steel balls are slidably connected in grooves evenly formed on the side wall of the battery casing. A first spring elastically supports the spherical steel balls between the spherical steel balls and the battery casing. A tail cap is fitted onto the battery casing and is pressed tightly against the stepped ring.

[0008] In some embodiments, the support mechanism includes a first slot formed on one side of the battery casing, a fixing block slidably connected in the first slot, the fixing block being fixed to the built-in battery, and a second spring being provided between the fixing block and the battery casing, and a support slide corresponding to the fixing block being formed on the side of the docking compartment near the battery casing.

[0009] In some embodiments, a second slot is provided on the other side of the battery casing, and a locking block is slidably connected in the second slot. The locking block is fixed to the built-in battery, and a locking strip is slidably connected in the locking block. The locking strip and the locking block are connected to each other by a third spring.

[0010] In some embodiments, the battery casing has a locking groove corresponding to the locking bar and an unlocking groove. The top of the locking groove is connected to the unlocking groove. An unlocking block that pushes the inclined surface of the locking bar is slidably connected in the unlocking groove. The unlocking block is fixed on the docking compartment.

[0011] This utility model has at least the following beneficial effects:

[0012] 1. In this utility model, the locking part between the docking compartment and the battery shell is unlocked by an unlocking button with elastic support. After the tail cover is fixed, the stepped ring and the sealing cover are rotatably connected to the battery shell. At the same time, the spherical steel ball is pushed into the spherical groove of the stepped ring under the support of the first spring to provide damping for the rotation of the sealing cover. Meanwhile, the unlocking button is sealed by the sealing cover to prevent accidental contact that could cause the battery to fall off.

[0013] 2. In this utility model, the built-in battery is slidably connected in the battery housing and elastically supported by a fixing block and a second spring. At the same time, the locking strip is pushed into the locking groove under the action of a third spring, rigidly fixing the built-in battery inside the battery housing. During the process of inserting the battery housing into the docking chamber, the unlocking block moves along the unlocking groove. After contacting the locking strip, it pushes the inclined surface at the top of the locking strip, causing the locking strip to move down. After the battery housing is fully inserted, the top of the locking strip disengages from the unlocking groove. The top pressure provided by the third spring makes the friction between the locking strip and the locking groove less than the elastic force of the second spring. At this time, the locking strip completely disengages from the locking groove. Then, the fixing block and the built-in battery are pushed into the docking chamber under the action of the second spring, providing elastic tension to prevent loose connection and poor contact, thereby ensuring the working stability of the vacuum cleaner.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figure 1-4 This utility model provides a technical solution: a vacuum cleaner with an easy-to-replace battery, including a vacuum cleaner body 1, a docking compartment 2 on the vacuum cleaner body 1, a battery case 3 slidably connected to the docking compartment 2, an unlocking button 4 elastically supported on the battery case 3, a built-in battery 6 slidably connected in the battery case 3, a protective mechanism 5 on the battery case 3 to prevent accidental activation of the unlocking button 4, and a support mechanism 7 elastically supporting the built-in battery 6 between the docking compartment 2 and the battery case 3; the battery case 3 matches the docking compartment 2 of the vacuum cleaner body 1 via a slide rail or guide groove, realizing quick insertion and removal of the battery without the need for tools, facilitating battery replacement, the battery can slide slightly within the battery case 3, and the support mechanism 7 keeps the electrodes in close contact, compensating for manufacturing tolerances and ensuring a stable connection between the battery and the vacuum cleaner contacts. Through the combination of sliding connection, elastic locking and anti-accidental activation design, stable power supply is guaranteed while greatly improving user experience and maintenance convenience.

[0024] Example 2:

[0025] Please see Figure 1-4The protective mechanism 5 includes a mounting groove 51 formed on the battery casing 3, a stepped ring 52 fitted onto the mounting groove 51, and a sealing cover 53 fitted onto the stepped ring 52. The sealing cover 53 is an incomplete arc structure. Symmetrical spherical grooves 54 providing rotational damping are formed on the inner wall of the stepped ring 52. Spherical steel balls 55 are connected in the spherical grooves 54 and slidably connected in the grooves evenly formed on the side wall of the battery casing 3. A first spring 56 elastically supports the spherical steel balls 55 between them and the battery casing 3. A tail cap 57 is fitted onto the battery casing 3 and is pressed tightly against the stepped ring 52. The sealing cover 53 is not... The complete arc structure allows for selective exposure or obstruction of the unlock button 4 during rotation. The stepped ring 52 serves as a rotating base, providing positioning damping through the spherical groove 54 and steel balls to ensure that the enclosure 53 remains stably in the set position. By default, the enclosure 53 obstructs the unlock button 4 to prevent accidental pressing during cleaning and subsequent battery dislodgement. The enclosure 53 must be actively rotated to unlock, improving operational safety. The steel balls are embedded in the spherical groove 54 of the stepped ring 52 under the elastic force of the first spring 56, creating a positioning feel and giving the enclosure 53 a segmented feel when rotating. The tail cap 57 presses against the stepped ring 52 to prevent axial movement while allowing the enclosure 53 to rotate freely.

[0026] The locking part between the docking compartment 2 and the battery casing 3 is unlocked by the elastically supported unlocking button 4. After the tail cover 57 is fixed, the stepped ring 52 and the sealing cover 53 are rotatably connected to the battery casing 3. At the same time, the spherical steel ball 55, supported by the first spring 56, pushes into the spherical groove 54 of the stepped ring 52 to provide damping for the rotation of the sealing cover 53. Meanwhile, the unlocking button 4 is sealed by the sealing cover 53 to prevent accidental contact that could cause the battery to fall off. When unlocking, rotate the sealing cover 53 and the stepped ring 52 so that the notch of the sealing cover 53 exposes the unlocking button 4. Then, press the unlocking button 4 to unlock and remove the battery.

[0027] Example 3:

[0028] Please see Figure 1-4The support mechanism 7 includes a first slot 71 on one side of the battery housing 3, in which a fixing block 72 is slidably connected. The fixing block 72 is fixed to the built-in battery 6, and a second spring 73 is provided between the fixing block 72 and the battery housing 3. A support slide corresponding to the fixing block 72 is provided on the side of the docking compartment 2 near the battery housing 3. A second slot 74 is provided on the other side of the battery housing 3, in which a locking block 75 is slidably connected. The locking block 75 is fixed to the built-in battery 6, and a locking strip 76 is slidably connected to the locking block 75. The locking strip 76 and the locking block 75 are connected to each other by a third spring 77. A locking groove 78 corresponding to the locking strip 76 is provided on the battery housing 3, and an unlocking groove 79 is provided on the battery housing 3. The top of the locking groove 78 communicates with the unlocking groove 79. An unlocking block 80 that pushes the inclined surface of the locking strip 76 is slidably connected to the unlocking groove 79, and the unlocking block 80 is fixed to the docking compartment 2. 2 is fixed to the battery and connected to the battery casing 3 by the second spring 73, allowing the battery to slide slightly inside the battery casing 3. The docking compartment 2 is provided with a support slide. When the battery casing 3 is inserted, the fixing block 72 moves along the slide, and the second spring 73 continuously provides elastic force, so that the battery presses tightly against the electrode contacts of the docking compartment 2. Even if there are slight dimensional errors in the battery or docking compartment 2, the spring force can still ensure that the electrodes are in close contact and avoid poor contact. The locking block 75 is fixed to the battery, and its internal locking strip 76 is pushed into the locking groove 78 of the battery casing 3 by the third spring 77, so that the battery is rigidly fixed when it is not inserted into the docking compartment 2, preventing it from loosening during transportation or storage. When the battery casing 3 is inserted into the docking compartment 2, the unlocking block 80 on the docking compartment 2 moves along the unlocking groove 79, and pushes the locking strip 76 down through the inclined surface to release the lock. When not inserted, the battery is mechanically locked to prevent accidental slippage. When inserted into the docking compartment 2, no manual operation is required, and the locking strip 76 automatically disengages.

[0029] The built-in battery 6 is slidably connected in the battery housing 3 and is elastically supported by the fixing block 72 and the second spring 73. At the same time, the locking bar 76 is pushed into the locking groove 78 under the action of the third spring 77, rigidly fixing the built-in battery 6 inside the battery housing 3. During the process of inserting the battery housing 3 into the docking compartment 2, the unlocking block 80 moves along the unlocking groove 79. After contacting the locking bar 76, it pushes the inclined surface at the top of the locking bar 76, causing the locking bar 76 to move downward. After the battery housing 3 is fully inserted, the top of the locking bar 76 disengages from the unlocking groove 79. The upward pressure provided by the third spring 77 keeps the locking bar 76 in contact with the locking groove 78. The friction between 8 is less than the elastic force of the second spring 73. At this time, the locking strip 76 is completely disengaged from the locking groove 78. Then, the fixing block 72 and the built-in battery 6 are pushed into the docking chamber 2 under the action of the second spring 73, providing elastic tension to avoid loose connection and poor contact, thereby ensuring the working stability of the vacuum cleaner. The support mechanism 7, through the dual mechanism of elastic support and rigid locking, ensures that the built-in battery 6 can be stably fixed in the battery shell 3, and can automatically elastically press the electrode after being inserted into the docking chamber 2, ensuring the stability of the vacuum cleaner's power supply and the convenience of battery replacement.

[0030] Example 4:

[0031] Please see Figure 1-6 This utility model provides a technical solution: a vacuum cleaner with easily replaceable batteries, including a vacuum cleaner body 1, a docking compartment 2 on the vacuum cleaner body 1, a battery housing 3 slidably connected to the docking compartment 2, an unlocking button 4 elastically supported on the battery housing 3, a built-in battery 6 slidably connected in the battery housing 3, a protective mechanism 5 on the battery housing 3 to prevent accidental activation of the unlocking button 4, and a support mechanism 7 elastically supporting the built-in battery 6 between the docking compartment 2 and the battery housing 3. Based on the above structure, a first sealing plate 101 and a second sealing plate 102 are added. The first sealing plate 101 and the second sealing plate 102 are respectively fixed to both sides of the docking compartment 2. The first sealing plate 101 closes the first slot 71 on one side of the battery housing 3, and the second sealing plate 102 closes the other side of the battery housing 3. The second slot 74, the fixing block 72 for elastically supporting the built-in battery 6, and the second spring 73 are covered by the first sealing plate 101. At the same time, the locking block 75, the locking strip 76, and the third spring 77, which lock the position of the built-in battery 6 when the battery case 3 is not inserted into the docking compartment 2, are covered by the second sealing plate 102. This prevents dust and liquid from entering the interior of the docking compartment 2 through the slot, and protects the internal support mechanism 7, the locking block 75, and the locking strip 76 from contamination or corrosion. After the battery case 3 is inserted into the docking compartment 2, there are no exposed slots or gaps on the outer surface, making the overall design simpler and smoother, which is in line with the design trend of modern home appliances. The flat sealing plate design prevents dust from accumulating in the slot, and users do not need to clean the complex grooves when wiping. At the same time, when maintenance is required, the sealing plate can be removed to directly access the internal mechanism, taking into account both daily protection and maintenance convenience.
