Description

Technical Field

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

[0002] As one of the main cleaning tools in the home, the stick-shaped cleaning brush is often used to clean small spaces (bathrooms, kitchens, etc.). It uses an electric drive to drive the cleaning head to rotate to clean dust.

[0003] To prevent dust from entering the battery compartment, the battery compartment is typically enclosed within a cleaning brush. During use, the batteries within the compartment generate heat, causing the battery temperature to rise. When the battery temperature is too high, a thermal fuse or other passive device is triggered, disconnecting the circuit. Because the battery is in a sealed environment, heat dissipation is slow, requiring a long wait before it can be used again. If a heat dissipation vent is directly placed in the battery compartment, dust, moisture, and other substances can enter, causing short circuits or poor contact, shortening battery life (e.g., moisture corroding the electrodes).

[0004] Therefore, how to provide a household cleaning auxiliary device that can meet the heat dissipation requirements while avoiding the heat dissipation vents from affecting the circuits and batteries in the battery compartment is a technical problem that needs to be solved urgently.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0042] After the cleaning is completed, the second connecting rod is rotated by external force so that the second connecting rod is in a folded state. At this time, the heat dissipation port of the battery compartment is sealed by the telescopic seal.

DETAILED DESCRIPTION

[0064] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0065] Research has found that in order to prevent external pollutants such as dust and water vapor from entering the battery compartment, the cleaning brush in the related technology has the battery compartment built into the handle of the cleaning brush. When the battery in the battery compartment is in use, as the temperature rises, it will trigger a self-protection mechanism, disconnecting the circuit and requiring a long wait before it can be used again.

[0066] Based on the above research, the embodiments of the present disclosure provide a household cleaning assistance device and a method for using the same. Through the linkage design of the telescopic seal 123 and the elastic member 124, when the battery 300 overheats, the elastic member 124 is triggered to deform by the heat, opening the heat dissipation port 122, significantly improving the heat dissipation efficiency, avoiding the problem of equipment downtime and waiting caused by high temperature triggering the thermal fuse, and shortening the reusable time of the household cleaning assistance device.

[0067] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0068] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0069] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0070] See also Figure 1-Figure 3 At least one embodiment provides a household cleaning auxiliary device, comprising the following structure:

[0071] The handle 100 is provided with a battery 300, a motor 400, a drive switch, a control circuit, etc.

[0072] The cleaning head 200 is rotatably disposed at the end of the handle 100 and is used for cleaning. The cleaning head 200 is driven to rotate by the motor 400 in the handle 100 .

[0073] Wherein, the handle 100 includes:

[0074] The first connecting rod 110 adopts a telescopic design and can be adjusted in height according to the user's usage habits.

[0075] The second connecting rod 120 is hinged to the first connecting rod 110 , and the motor 400 , the battery 300 , and the control circuit are disposed in the second connecting rod 120 .

[0076] See also Figure 3 and Figure 4A battery compartment 121 is provided at one end of the second connecting rod 120 close to the first connecting rod 110, and a heat dissipation vent 122 is provided on the top wall of the battery compartment 121. The heat dissipation vent 122 dissipates heat from the battery 300 in the battery compartment 121, thereby improving the heat dissipation capacity of the battery 300.

[0077] A telescopic seal 123 is provided on the heat dissipation opening 122, and is used to seal the heat dissipation opening 122 of the battery compartment 121 of the second link 120 in a folded state, and is also used to cover the battery compartment 121 of the second link 120 in a flattened state and the hinge 130 between the first link 110 and the second link 120.

[0078] An elastic member 124 connected to the bottom of the telescopic seal 123 is provided in the battery compartment 121 , and is used to push the telescopic seal 123 upwards through the elastic member 124 to open the heat dissipation vent 122 when the battery 300 in the battery compartment 121 overheats.

[0079] By setting a telescopic seal 123 at the heat dissipation port 122 of the battery compartment 121, in the folded state, the first link 110 applies pressure to the telescopic seal 123, compressing and completely sealing the heat dissipation port 122 to prevent external contaminants from entering. In the flattened state, the telescopic seal 123 unfolds to cover the hinge 130 between the first link 110 and the second link 120 and the heat dissipation port 122, reducing the total amount of dust entering the hinge 130 and preventing dust and water vapor from penetrating into the battery compartment 121.

[0080] At the same time, in the flattened state, when the battery 300 overheats, the elastic member 124 is triggered to deform by the heat, pushing the telescopic seal 123 upward, opening the heat dissipation port 122, improving the heat dissipation efficiency of the battery 300, avoiding the problem of equipment downtime and waiting caused by high temperature triggering the thermal fuse, and shortening the reusable time of the household cleaning auxiliary device.

[0081] Please continue reading Figure 3 and Figure 4 The telescopic seal 123 includes: a telescopic plate 1231; the battery compartment 121 is provided with a slot 1211 connected to the heat dissipation port 122; one end of the telescopic plate 1231 is elastically connected to the slot 1211 through a return spring 1212; a sealing ring 1232, which is arranged at the bottom of the telescopic plate 1231 and at the end of the telescopic plate 1231 away from the slot 1211.

[0082] In the folded state, one end of the telescopic plate 1231 is pressed into the slot 1211 by the first connecting rod 110, and the heat dissipation opening 122 is sealed by the sealing ring 1232. The pressing direction of the telescopic plate 1231 is as follows: Figure 5 As shown in F, the first connecting rod 110 applies pressure to the telescopic plate 1231, pressing the telescopic plate 1231 into the slot 1211, thereby completely sealing the heat dissipation opening 122 and preventing external contaminants from entering.

[0083] In the flattened state, the other end of the telescopic plate 1231 is extended from the heat dissipation port 122 by the return spring 1212 to cover the hinge 130 between the first link 110 and the second link 120. The extension direction of the telescopic plate 1231 is as follows: Figure 4 As shown in FIG. F, when the telescopic plate 1231 extends partially from the heat dissipation port 122, it covers the hinge 130 between the first link 110 and the second link 120 and the heat dissipation port 122, thereby reducing the amount of dust entering the hinge 130 and preventing dust and moisture from penetrating into the battery compartment 121.

[0084] Please continue reading Figure 4 A supporting plate 1213 is provided below the heat dissipation opening 122 ; a height H of a gap between the telescopic plate 1231 and the supporting plate 1213 is smaller than a thickness L of the sealing ring 1232 .

[0085] When one end of the telescopic plate 1231 is pressed into the slot 1211 by the first connecting rod 110 , the sealing ring 1232 is squeezed by the supporting plate 1213 , thereby improving the sealing between the telescopic plate 1231 and the heat dissipation port 122 .

[0086] Please continue reading Figure 4 and Figure 5 An air cavity 1232a is provided in the sealing ring 1232, and an air hole 1232b is provided downwardly on the side of the sealing ring 1232 away from the slot 1211; when switching from the flat state to the folded state, the sealing ring 1232 is squeezed by the supporting plate 1213 to discharge the gas in the sealing ring 1232 from the air hole 1232b, and the hinge 130 between the first connecting rod 110 and the second connecting rod 120 is cleaned.

[0087] The schematic diagram of the support plate 1213 squeezing the sealing ring 1232 is shown in FIG. Figure 8 shown.

[0088] When one end of the telescopic plate 1231 is pressed into the slot 1211 through the first connecting rod 110, that is, when it is rotated from the flat state to the folded state, the air cavity 1232a in the sealing ring 1232 is squeezed by the supporting plate 1213, so that the gas in the air cavity 1232a is discharged from the air hole 1232b, thereby cleaning the dust at the hinge 130 between the first connecting rod 110 and the second connecting rod 120.

[0089] See also Figure 5When in the folded state, the side plate of the sealing ring 1232 with the air hole 1232 b abuts against the top of the abutting plate 1213 to seal the heat dissipation port 122 .

[0090] In the folded state, the sealing ring 1232 and the abutting plate 1213 are adsorbed by the negative pressure of the air cavity 1232 a in the sealing ring 1232 , thereby improving the sealing between the telescopic plate 1231 and the abutting plate 1213 .

[0091] See also Figure 4 and Figure 6 The elastic member 124 includes: a rotating plate 1241, which is rotatably arranged at the bottom of the battery compartment 121 via a rotating shaft 1241a; a connecting plate 1242, which is arranged at one end of the rotating plate 1241 away from the rotating shaft 1241a and is used to connect with the telescopic plate 1231; a thermal control driving unit 1243, which is used to drive the rotating plate 1241 to rotate along the rotating shaft 1241a when the battery 300 in the battery compartment 121 is overheated, so as to push the telescopic plate 1231 upward (the pushing direction is as shown in FIG. Figure 6 As shown in F in FIG. 1 ), the heat dissipation vent 122 is opened.

[0092] In the flattened state, when the battery 300 overheats, the thermal control drive unit 1243 is triggered to deform by the heat, driving the rotating plate 1241 to rotate along the rotating axis 1241a, pushing the telescopic seal 123 upward, opening the heat dissipation port 122, improving the heat dissipation efficiency of the battery 300, avoiding the equipment downtime and waiting problem caused by high temperature triggering the thermal fuse, and shortening the reusable time of the household cleaning auxiliary device.

[0093] In a preferred embodiment, the thermal control driving unit 1243 is a bimetallic composite layer; the bimetallic composite layer is disposed between the rotating plate 1241 and the battery compartment 121 .

[0094] Specifically, the bimetallic composite layer includes an active layer and a passive layer. The active layer is made of nickel-chromium alloy, and its thermal expansion coefficient is 18×10 -6 / °C, the passive layer is made of Invar steel, and its thermal expansion coefficient is 1.2×10 -6 / °C, the active layer is arranged below the passive layer, and the trigger temperature is set by the thickness ratio of the active layer and the bimetallic composite layer. For example, 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 greater than that of the passive layer, the passive layer bulges upward and the active layer sinks downward, causing the bimetallic 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 in FIG. Figure 6As shown in F in FIG. 1 ), the heat dissipation vent 122 is opened.

[0095] See also Figure 6 and Figure 7 A sliding groove 1233 is provided at the bottom of the telescopic plate 1231 ; the end of the connecting plate 1242 away from the rotating plate 1241 is slidably provided in the sliding groove 1233 .

[0096] See also Figure 9 At least one embodiment further provides a method for using the household cleaning auxiliary device as described above, the method comprising:

[0097] S110 , rotating the second connecting rod 120 by an external force so that the second connecting rod 120 is in a flattened state.

[0098] Specifically, the second connecting rod 120 is manually rotated to be in a flattened state and enter a use state.

[0099] S120 , covering the heat dissipation opening 122 and the hinge 130 between the first connecting rod 110 and the second connecting rod 120 with the telescopic seal 123 .

[0100] S130 , triggering the driving switch to enable the motor 400 in the second connecting rod 120 to drive the cleaning head 200 to rotate.

[0101] S140 , when the battery 300 in the battery compartment 121 is overheated, the retractable sealing member 123 is pushed upward by the elastic member 124 to open the heat dissipation vent 122 .

[0102] S150 , after the heat dissipation of the battery 300 is completed, the telescopic seal 123 is reset by external force to close the heat dissipation port 122 .

[0103] S160, after the cleaning is completed, the second connecting rod 120 is rotated by external force so that the second connecting rod 120 is in a folded state. At this time, the heat dissipation port 122 of the battery compartment 121 is sealed by the telescopic sealing member 123.

[0104] Specifically, the second link 120 is manually rotated to be in a folded state, that is, a non-use state.

[0105] In summary, the present invention discloses a household cleaning auxiliary device and a method for using the same, wherein the household cleaning auxiliary device comprises: a handle 100; a cleaning head 200; wherein the handle 100 comprises: a first connecting rod 110; a second connecting rod 120, which is hinged to the first connecting rod 110; a battery compartment 121 is provided at one end of the second connecting rod 120 close to the first connecting rod 110, and a heat dissipation vent 122 is provided on the top wall of the battery compartment 121; a telescopic seal 123 is provided on the heat dissipation vent 122, and is used to dissipate heat from the heat dissipation vent 12 ... The heat dissipation vent 122 of the battery compartment 121 of the second link 120 in the folded state is sealed, and the battery compartment 121 of the second link 120 in the flattened state and the hinge 130 between the first link 110 and the second link 120 are covered; an elastic member 124 connected to the bottom of the telescopic seal 123 is provided in the battery compartment 121, and is used to push the telescopic seal 123 upward through the elastic member 124 to open the heat dissipation vent 122 when the battery 300 in the battery compartment 121 is overheated. By providing a retractable seal 123 at the heat dissipation vent 122 of the battery compartment 121, when folded, the first link 110 applies pressure to the retractable seal 123, compressing and completely sealing the heat dissipation vent 122, preventing the ingress of external contaminants. When flattened, the retractable seal 123 expands to cover the hinge 130 between the first and second links 110, 120, and the heat dissipation vent 122, reducing the amount of dust entering the hinge 130 and preventing dust and moisture from seeping into the battery compartment 121. Furthermore, in the flattened state, when the battery 300 overheats, the elastic member 124 is triggered by heat to deform, pushing the retractable seal 123 upward, opening the heat dissipation vent 122. This improves the heat dissipation efficiency of the battery 300, avoids device downtime caused by high temperatures triggering a thermal fuse, and shortens the reusability of the household cleaning aid.
