Description

Technical Field

[0001] The present invention belongs to the technical field of household cleaning equipment, specifically relates to household dust removal equipment, and particularly relates to a household cleaning auxiliary device and a using method thereof. Background Art

[0002] As one of the main household cleaning tools, the rod-shaped cleaning brush is often used for cleaning narrow spaces (such as bathrooms, kitchens, etc.). It drives the cleaning head to rotate in an electric drive mode to clean dust.

[0003] In related technologies, in order to prevent dust from entering the battery compartment, the battery compartment is generally built into the cleaning brush. When the battery in the battery compartment is in use, it will generate heat, resulting in an increase in the battery temperature. When the battery temperature is too high, it will trigger components such as a thermal fuse to disconnect the circuit. Since the battery is in a closed environment, the battery heat dissipation is too slow, and it takes a long time to be used again. If a heat dissipation opening is directly opened in the battery compartment, dust, water vapor, etc. will enter the battery compartment, resulting in a short circuit or poor contact of the circuit, affecting the battery life (water vapor causes electrode corrosion, etc.).

[0004] Therefore, how to provide a household cleaning auxiliary device that can meet the heat dissipation requirements while avoiding the influence of the heat dissipation opening on the circuit and battery in the battery compartment is a technical problem that needs to be solved urgently at present.

[0027] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

[0028] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0029] Please refer to Figures 1 - 3 , at least one embodiment provides a household cleaning assistance device, including the following structures: A handle 100, which is internally provided with a battery 300, a motor 400, a drive switch, a control circuit, etc.

[0030] A cleaning head 200, which is rotatably arranged at the end of the handle 100 and is used for cleaning, and the cleaning head 200 is driven to rotate by the motor 400 in the handle 100.

[0031] Among them, the handle 100 includes: A first link 110, which adopts a telescopic design and is adjusted in height according to the user's usage habit.

[0032] A second link 120, which is hinged to the first link 110, and the motor 400, the battery 300, the control circuit, etc. are arranged in the second link 120.

[0033] Please refer to Figure 3 and Figure 4 , one end of the second link 120 close to the first link 110 is provided with a battery compartment 121, and a heat dissipation port 122 is provided on the top wall of the battery compartment 121. By providing the heat dissipation port 122, heat dissipation of the battery 300 in the battery compartment 121 is carried out, and the heat dissipation capacity of the battery 300 is improved.

[0034] A telescopic seal 123 is provided on the heat dissipation port 122, and is used for sealing the heat dissipation port 122 of the battery compartment 121 of the second link 120 in the folded state, and is also used for covering the battery compartment 121 of the second link 120 and the hinge joint 130 between the first link 110 and the second link 120 in the flattened state.

[0035] An elastic member 124 connected to the bottom of the telescopic seal 123 is arranged in the battery compartment 121, and is used for pushing the telescopic seal 123 upward through the elastic member 124 when the battery 300 in the battery compartment 121 overheats, and opening the heat dissipation port 122.

[0036] By providing a telescopic seal 123 at the heat dissipation opening 122 of the battery compartment 121, in the folded state, the first link 110 applies pressure to the telescopic seal 123, causing it to compress and completely seal the heat dissipation opening 122, preventing external contaminants from entering. In the flattened state, the telescopic seal 123 unfolds to cover the hinge joint 130 between the first link 110 and the second link 120 as well as the heat dissipation opening 122, reducing the total amount of dust entering the hinge joint 130 and preventing dust and moisture from seeping into the battery compartment 121.

[0037] Meanwhile, in the flattened state, when the battery 300 overheats, the elastic member 124 is triggered to deform by heat, pushing the telescopic seal 123 upward to open the heat dissipation opening 122, improving the heat dissipation efficiency of the battery 300, avoiding the problem of equipment downtime waiting caused by high temperature triggering the thermal fuse, and shortening the reusable time of the household cleaning assistance device.

[0038] Please continue to refer to Figure 3 and Figure 4 The telescopic seal 123 includes: a telescopic plate 1231; a slot 1211 communicating with the heat dissipation opening 122 is provided in the battery compartment 121; one end of the telescopic plate 1231 is elastically connected in the slot 1211 through a return spring 1212; a sealing ring 1232 is provided at the bottom of the telescopic plate 1231 and at one end of the telescopic plate 1231 away from the slot 1211.

[0039] In the folded state, one end of the telescopic plate 1231 is pressed into the slot 1211 by the first link 110, and the heat dissipation opening 122 is sealed by the sealing ring 1232. The pressing direction of the telescopic plate 1231 is as shown by F in Figure 5 The first link 110 applies pressure to the telescopic plate 1231, causing it to be pressed into the slot 1211 to completely seal the heat dissipation opening 122 and prevent external contaminants from entering.

[0040] In the flattened state, the other end of the telescopic plate 1231 is extended from the heat dissipation opening 122 by the return spring 1212 to cover the hinge joint 130 between the first link 110 and the second link 120. The extending direction of the telescopic plate 1231 is as shown by F in Figure 4 When the telescopic plate 1231 extends from the heat dissipation opening 122, it covers both the hinge joint 130 between the first link 110 and the second link 120 and the heat dissipation opening 122, reducing the total amount of dust entering the hinge joint 130 and preventing dust and moisture from seeping into the battery compartment 121.

[0041] Please continue to refer to Figure 4, a supporting plate 1213 is provided below the heat dissipation port 122; the height H of the gap between the telescopic plate 1231 and the supporting plate 1213 is less than the thickness L of the sealing ring 1232.

[0042] When one end of the telescopic plate 1231 is pressed into the slot 1211 through the first connecting rod 110, the sealing ring 1232 is extruded by the supporting plate 1213, improving the sealing performance between the telescopic plate 1231 and the heat dissipation port 122.

[0043] Please continue to refer to Figure 4 and Figure 5 , an air cavity 1232a is provided inside the sealing ring 1232, and an air hole 1232b is provided downward on the side of the sealing ring 1232 away from the slot 1211; when switching from the flattened state to the folded state, the sealing ring 1232 is extruded by the supporting plate 1213 to discharge the gas inside the sealing ring 1232 from the air hole 1232b and clean the hinge joint 130 between the first connecting rod 110 and the second connecting rod 120.

[0044] A schematic diagram of the supporting plate 1213 extruding the sealing ring 1232 is as shown in Figure 8 shown.

[0045] When one end of the telescopic plate 1231 is pressed into the slot 1211 through the first connecting rod 110, that is, when rotating from the flattened state to the folded state, the air cavity 1232a inside the sealing ring 1232 is extruded by the supporting plate 1213, causing the gas inside the air cavity 1232a to be discharged from the air hole 1232b, thereby cleaning the dust at the hinge joint 130 between the first connecting rod 110 and the second connecting rod 120.

[0046] Please refer to Figure 5 , in the folded state, the side plate of the sealing ring 1232 provided with the air hole 1232b abuts against the top of the supporting plate 1213 to seal the heat dissipation port 122.

[0047] In the folded state, the sealing ring 1232 and the supporting plate 1213 are adsorbed by the negative pressure in the air cavity 1232a inside the sealing ring 1232, thereby improving the sealing performance between the telescopic plate 1231 and the supporting plate 1213.

[0048] Please refer to Figure 4 and Figure 6, the elastic member 124 includes: a rotating plate 1241 rotatably disposed at the bottom of the battery compartment 121 through a rotating shaft 1241a; a connecting plate 1242 disposed at an end of the rotating plate 1241 away from the rotating shaft 1241a and for connecting to the telescopic plate 1231; a thermal control driving portion 1243 for driving the rotating plate 1241 to rotate along the rotating shaft 1241a when the battery 300 in the battery compartment 121 overheats, so as to push the telescopic plate 1231 upward (the pushing direction is as shown by F in Figure 6 ), thereby opening the heat dissipation opening 122.

[0049] In the flattened state, when the battery 300 overheats, the thermal control driving portion 1243 is triggered by heat and deforms, driving the rotating plate 1241 to rotate along the rotating shaft 1241a, pushing the telescopic seal 123 upward, opening the heat dissipation opening 122, improving the heat dissipation efficiency of the battery 300, avoiding the problem of equipment downtime waiting caused by the thermal fuse being triggered by high temperature, and shortening the reusable time of the household cleaning auxiliary device.

[0050] In a preferred embodiment, the thermal control driving portion 1243 is a bimetal composite layer; the bimetal composite layer is disposed between the rotating plate 1241 and the battery compartment 121.

[0051] Specifically, the bimetal composite layer includes an active layer and a passive layer. The active layer is made of nickel-chromium alloy with a thermal expansion coefficient of 18×10 -6 / °C, and the passive layer is made of invar with a thermal expansion coefficient of 1.2×10 -6 / °C. The active layer is disposed below the passive layer. By setting the thickness ratio of the active layer to the bimetal composite layer, the triggering temperature is set. For example, when the thickness ratio of the nickel-chromium alloy is 0.65, at this time, when the temperature of the battery 300 is 70°C, since the thermal expansion coefficient of the active layer is much larger than that of the passive layer, at this time, the passive layer bulges upward and the active layer depresses downward, causing the bimetal composite layer to expand, thereby driving the rotating plate 1241 to rotate about 15° along the rotating shaft 1241a to push the telescopic plate 1231 upward (the pushing direction is as shown by F in Figure 6 ), thereby opening the heat dissipation opening 122.

[0052] Please refer to Figure 6 and Figure 7 , a chute 1233 is provided at the bottom of the telescopic plate 1231; one end of the connecting plate 1242 away from the rotating plate 1241 is slidably disposed in the chute 1233.

[0054] Specifically, rotate the second link 120 manually to make it in a flattened state and enter the use state.

[0055] S120. Cover the heat dissipation port 122 and the hinge joint 130 between the first link 110 and the second link 120 with the telescopic seal 123.

[0056] S130. Trigger the drive switch to make the motor 400 in the second link 120 drive the cleaning head 200 to rotate.

[0057] S140. When the battery 300 in the battery compartment 121 overheats, push the telescopic seal 123 upward through the elastic member 124 to open the heat dissipation port 122.

[0059] S160. After the cleaning is completed, rotate the second link 120 by an external force to make the second link 120 in a folded state. At this time, seal the heat dissipation port 122 of the battery compartment 121 with the telescopic seal 123.
