Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and particularly relates to an electric fabric cleaning machine. Background Art

[0002] In people's daily life, after long-term use, the surfaces of fabric items such as sofas, carpets, curtains, and leather seats will be attached with dust, bacteria, and stubborn stains. For these surface dirt, there are already special fabric cleaning machines to clean them.

[0003] For example, the utility model patent with the patent authorization announcement number: CN217565904U. This patent discloses a fabric cleaning machine, which includes a cleaning machine body with a motor installed therein; a suction head detachably connected to the cleaning machine body; a gas-liquid separation component arranged in the cleaning machine body. The gas-liquid separation component includes a sewage tank, a first air inlet pipe, a second air inlet pipe, and a plugging member. The first air inlet pipe, the second air inlet pipe, and the plugging member are all located in the sewage tank. The first air inlet pipe passes through the sewage tank and is connected to the suction head. One end of the second air inlet pipe is communicated with the first air inlet pipe and the other end passes through the sewage tank and is communicated with the suction port of the motor. The plugging member is movably connected to the second air inlet pipe.

[0004] Based on the retrieval of the above patent authorization announcement number and combined with its deficiencies, it is found that: Existing fabric cleaning machines can only remove the stains on the surface of fabric items, but cannot remove the mites attached inside the fabric items. The reason is that existing fabric cleaning machines cannot immediately kill mites. When the suction head adsorbs the fabric item, the mites attached inside the fabric item still have the strength to hook themselves inside the fabric item and are not sucked away by the suction head, thus resulting in the fabric cleaning machine being unable to remove the mites attached inside the fabric item.

The reason is that the existing fabric cleaning machines cannot kill the mites immediately, so that when the suction head adsorbs the fabric article, the mites attached to the fabric article still have the strength to hook themselves in the fabric article and are not sucked away by the suction head, resulting in the problem that the fabric cleaning machine cannot remove the mites attached to the fabric article.

[0020] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in combination with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects according to the present invention as follows.

[0021] Please refer to Figures 1-6, this embodiment provides an electric fabric cleaning machine, which includes a cleaning housing 1 with a hollow interior, a spraying pump 2, a spraying tank 3 filled with cleaning water, and a nozzle 4. The spraying pump 2 and the spraying tank 3 are both arranged inside the cleaning housing 1. The spraying pump 2 is respectively connected to the spraying tank 3 and the nozzle 4. It also includes a heating module 5 and an adsorption assembly 6. The heating module 5 is arranged inside the spraying tank 3 and is used to heat the temperature of the cleaning water. The adsorption assembly 6 includes an adsorption pump 601, a suction head 602, an adsorption tank 603 with a hollow interior, a battery, and a power switch. The adsorption pump 601 and the adsorption tank 603 are arranged inside the cleaning housing 1. Both ends of the adsorption pump 601 are respectively connected to the suction head 602 and the adsorption tank 603. The battery is arranged inside the cleaning housing 1. The power switch is embedded on the surface of the cleaning housing 1. The power switch is provided with an input end and an output end. The battery is connected to the input end of the power switch through an electric wire. The output end of the power switch is respectively connected to the spraying pump 2 and the adsorption pump 601 through another electric wire. The power switch is of a push-button structure. By pressing once, the input end and the output end of the power switch are connected to each other, and thus the battery supplies power to the spraying pump 2 and the adsorption pump 601. By pressing twice, the input end and the output end of the power switch are disconnected from each other, and the battery stops supplying power to the spraying pump 2 and the adsorption pump 601. In this solution, by setting the heating module 5, the heating module 5 heats the cleaning water until the cleaning water reaches the specified temperature, and then the spraying pump 2 starts to work, spraying the heated cleaning water from the spraying tank 3 through the nozzle 4, achieving the effect of spraying hot water on fabric items by the nozzle 4. Due to the high-temperature characteristics of hot water, mites in the fabric items will immediately lose their activity after coming into contact with the hot water. Then, the adsorption pump 601 starts to work, creating a negative pressure inside the adsorption tank 603, making the suction head 602 connected to it have suction. When the suction head 602 is placed on the fabric item, the suction effect of the suction head 602 will absorb the mites and the cleaning water with stains in the fabric item into the adsorption tank 603 together, achieving the removal of mites and stains in the fabric item by this device. It solves the problem that existing fabric cleaning machines can only remove stains on the surface of fabric items but cannot remove mites attached inside the fabric items. The reason is that existing fabric cleaning machines cannot immediately kill mites, so when the suction head 602 adsorbs the fabric item, the mites attached inside the fabric item still have the ability to hook themselves inside the fabric item and are not sucked away by the suction head 602, resulting in the fabric cleaning machine being unable to remove mites attached inside the fabric item.

[0022] Specifically, it should be noted that during the actual operation of the adsorption pump 601 in this solution, a negative pressure is generated in the adsorption tank 603, thereby achieving the effect that the suction head 602 has suction force. Therefore, during the operation of the adsorption pump 601, it cannot adhere to the cleaning water. Based on this, to ensure the normal operation of the adsorption pump 601, the adsorption component 6 in this solution further includes a liquid suction pipe 604 and a gas suction pipe 605. The output end of the adsorption pump 601 is interconnected with the cleaning housing 1, and the output end of the adsorption pump 601 is interconnected with the outside. The two ends of the gas suction pipe 605 are respectively connected to the adsorption tank 603 and the input end of the adsorption pump 601, and the two ends of the liquid suction pipe 604 are respectively connected to the adsorption tank 603 and the suction head 602. The connection height of the liquid suction pipe 604 with the adsorption tank 603 is lower than the connection height of the gas suction pipe 605 with the adsorption tank 603. With such a setting, when the adsorption pump 601 starts to operate, the adsorption pump 601 will transmit the air in the adsorption tank 603 to the output end of the adsorption pump 601 through the output end of the adsorption pump 601 until the air in the adsorption tank 603 is transmitted to the outside atmosphere through the adsorption pump 601, generating a negative pressure in the adsorption tank 603, thereby achieving the effect that the suction head 602 has suction force. It should be noted that when the suction head 602 is placed on the fabric product for operation, the mites and the cleaning water with stains in the fabric product will be absorbed into the adsorption tank 603 through the liquid suction pipe 604 due to the suction effect of the suction head 602. Due to the effect of gravity, the mites and the cleaning water with stains absorbed into the adsorption tank 603 will directly fall to the bottom of the adsorption tank 603 and cannot move into the gas suction pipe 605 at the top of the connection between the liquid suction pipe 604 and the adsorption tank 603, ensuring the normal operation of the adsorption pump 601.

[0023] Further, to facilitate the user to use the nozzle 4 and the suction head 602 of this solution, this solution further includes a handheld housing 7 with a hollow interior and a hose 8. A communication hole communicating with its interior is provided in the side wall of the cleaning housing 1. An inflow port is provided at one end of the handheld housing 7, and a spraying slot hole and a suction slot hole communicating with the inflow port are provided at the other end thereof. The two ends of the hose 8 are respectively communicated with the communication hole and the inflow port. The nozzle 4 is arranged in the spraying slot hole, and the suction head 602 is arranged in the suction slot hole. Along the sliding direction of the handheld housing 7, the spraying slot hole is arranged in front of the suction slot hole; by providing the handheld housing 7, both the suction head 602 and the nozzle 4 are arranged in the handheld housing 7, and the suction head 602 is arranged in the suction slot hole, and the nozzle 4 is arranged in the spraying slot hole. Then, the two ends of the hose 8 are respectively communicated with the communication hole and the inflow port of the handheld housing 7. Such a setting enables the hose 8 and the handheld housing 7 to jointly form a connection space. One end of the water pipe communicating the spraying pump 2 with the nozzle 4 and one end of the liquid suction pipe 604 both extend into the connection space through the communication hole and are respectively connected to the corresponding nozzle 4 and suction head 602; by installing both the nozzle 4 and the suction head 602 in the handheld housing 7, and along the sliding direction of the handheld housing 7, the spraying slot hole is arranged in front of the suction slot hole, so that the user only needs to hold the handheld housing 7 and attach the end face of the handheld housing 7 close to the spraying slot hole and the suction slot hole to the fabric article, then the fabric article can be first subjected to hot water spraying treatment, and then the mites and the cleaning water with stains adhered in the fabric article can be adsorbed and removed.

[0024] According to the description of the above embodiment, when the spraying pump 2 starts to work, the spraying pump 2 will spray the high-temperature cleaning water from the nozzle 4. There will be two situations here. The first is that when the high-temperature cleaning water is sprayed towards the fabric article, the water vapor of the high-temperature cleaning water will float out from the gap between the handheld housing 7 and the fabric article, and there is a risk of scalding the user. The second is that when the device is accidentally touched, the spraying pump 2 is controlled to start working, resulting in the high-temperature cleaning water being sprayed towards the user's body, and there is also a risk of scalding the user.

[0025] To solve the problems in the first case and avoid its occurrence, this solution further includes a limiting component 9. The limiting component 9 includes an annular telescopic block 901. The end face of the handheld housing 7 where the ejection slot is located is a flat surface. The telescopic block 901 is arranged around the end face of the handheld housing 7 where the ejection slot is located. The projection position of the telescopic block 901 on the end face of the handheld housing 7 surrounds the ejection slot and the adsorption slot. By providing the telescopic block 901, since the projection position of the telescopic block 901 on the end face of the handheld housing 7 surrounds the ejection slot and the adsorption slot, and the bottom surface of the telescopic block 901 is a flat surface, when the handheld housing 7 is placed on a fabric item, the telescopic block 901 and the handheld housing 7 will jointly form a closed space. Both the nozzle 4 and the suction head 602 are within the closed space. When the nozzle 4 operates, due to the presence of the telescopic block 901, the water vapor within the closed space cannot flow out of the closed space, thus avoiding the occurrence of the first case.

[0026] To solve the problems in the second case and avoid its occurrence, the limiting component 9 of this solution further includes a number of limiting springs 902, a driving unit 10, and a limiting block 903. The end face of the handheld housing 7 is provided with a telescopic slot. The telescopic block 901 is arranged in the telescopic slot in a liftable manner. A number of limiting springs 902 are arranged in the telescopic slot at equal intervals along the setting direction of the telescopic slot. The two ends of the limiting spring 902 are respectively connected to the telescopic block 901 and the handheld housing 7. The handheld housing 7 is further provided with a driving slot 701. The driving slot 701 communicates with the telescopic slot. The driving unit 10 is arranged in the driving slot 701. The two ends of the driving unit 10 are respectively connected to the limiting block 903 and the telescopic block 901. The limiting block 903 can lock or release the connection relationship between the nozzle 4 and the fabric item. It should also be noted here that there is a certain distance between the end face of the nozzle 4 of this solution and the end face of the ejection slot, that is, the end face of the nozzle 4 is retracted within the end face of the handheld housing 7. The limiting block 903 is rotatably arranged within the closed space. In the initial state, the end face of the limiting block 903 is buckled on the end face of the ejection slot, that is, the limiting block 903 contacts the connection relationship between the nozzle 4 and the fabric item. At this time, even if the ejection pump 2 is accidentally touched and operates, the nozzle 4 cannot eject the cleaning water. Only when the handheld housing 7 is placed on a fabric item and the handheld housing 7 is pressed in the direction of the fabric item, the telescopic block 901 will move towards the top of the telescopic slot due to the pressing force, and then drive the connected driving unit 10 to move. Since the other end of the driving unit 10 is connected to the limiting block 903, the driving unit 10 will control the movement of the limiting block 903. The limiting block 903 is no longer buckled on the end face of the ejection slot, so that the limiting block 903 locks the connection relationship between the nozzle 4 and the fabric item. At this time, the nozzle 4 can operate normally and spray the cleaning water onto the fabric item. Through such a setting, the problems in the second case can be solved and the occurrence of the second case can be avoided.

[0027] Specifically, the driving unit 10 of this solution includes a connecting rod 1001, a lifting block 1002, and a return spring 1003. The lifting block 1002 is disposed in the driving slot 701 in a liftable manner. The connecting rod 1001 is horizontally connected to the lifting block 1002 and the telescopic block 901. One end of the limiting block 903 is hingedly arranged with the bottom end of the lifting block 1002. The two ends of the return spring 1003 are respectively connected to the lifting block 1002 and the limiting block 903. The sliding direction of the lifting block 1002 is perpendicular to the end face when the limiting block 903 releases the communication relationship between the nozzle 4 and the fabric article, and the hinged end between the lifting block 1002 and the limiting block 903 is located directly below the lifting block 1002; through such a setting, the limiting block 903 will rotate along its hinged end with the lifting block 1002. Since the hinged end between the lifting block 1002 and the limiting block 903 is located directly below the lifting block 1002, when the telescopic block 901 moves towards the top of the telescopic slot, the telescopic block 901 will drive the lifting block 1002 to move through the connecting rod 1001, causing the lifting block 1002 to move towards the top of the driving slot 701; during the movement of the lifting block 1002 towards the top of the driving slot 701, the limiting block 903 abuts against the end face of the driving slot 701, thereby forcing the limiting block 903 to rotate, causing the limiting block 903 to rotate along its hinged end with the lifting block 1002, realizing the transformation of the limiting block 903 from its original horizontal state to a vertical state, and realizing the transformation of the limiting block 903 from its original state of being buckled on the end face of the ejection slot to a state where the limiting block 903 releases the mutual buckling fit relationship with the end face of the ejection slot, thereby realizing the locking of the communication relationship between the limiting block 903, the nozzle 4, and the fabric article; and when the handheld housing 7 leaves the fabric article, due to the limiting spring 902, the telescopic block 901 will return to its original position, and the telescopic block 901 will move towards the bottom of the driving slot 701 again, thereby driving the connecting rod 1001 and the lifting block 1002 to move towards the bottom. The hinged end of the lifting block 1002 and the limiting block 903 will move towards the bottom in the driving slot 701 until the hinged end of the lifting block 1002 and the limiting block 903 moves out of the driving slot 701. At this time, under the action of the return spring 1003, the limiting block 903 rotates again, causing the limiting block 903 to be buckled on the end face of the ejection slot again.

[0028] According to the description of the above embodiments, the mites and stains attached to fabric articles are to be removed in this solution. Common fabric articles include pillowcases, sofa covers, etc. The characteristics of such fabric articles are that the knitting gaps on their surface layer are relatively small, and the speed at which the cleaning water penetrates from their surface layer into their inner layer is slow. Moreover, in a closed space, the space of the nozzle 4 and the space of the suction head 602 are interconnected. When the nozzle 4 sprays the cleaning water onto such fabric articles, the cleaning water has not fully penetrated into the inner layer of such fabric articles and will be absorbed into the adsorption tank 603 by the suction force of the suction head 602, reducing the cleaning effect of the device on the fabric articles. Based on this, to solve this problem, when the limiting block 903 is vertically arranged, that is, after the limiting block 903 releases the mating relationship with the end face of the ejection slot hole, the bottom surface of the limiting block 903 is at the same height as the bottom surface of the telescopic block 901, and the limiting block 903 divides the original closed space into two sealed spaces, that is, the limiting block 903, the telescopic block 901, and the handheld housing 7 together form two sealed spaces. The two sealed spaces correspond and match with the ejection slot hole and the adsorption slot hole, and any one of the sealed spaces is interconnected with the ejection slot hole or the adsorption slot hole. The limiting block 903 is also provided with a limiting hole 9031, and the limiting hole 9031 is respectively interconnected with the ejection slot hole and the adsorption slot hole. Through such a setting, since the limiting block 903 divides the original closed space into two sealed spaces after being vertically arranged, the cleaning water that has not penetrated into the fabric article after the nozzle 4 sprays the cleaning water onto the fabric article will not flow into another sealed space, ensuring that after the nozzle 4 sprays the cleaning water onto the fabric article, the cleaning water will first penetrate into the fabric article and then the suction head 602 will absorb and collect the cleaning water located inside the fabric article. It should also be noted that in order to enable the water vapor in the sealed space located at the nozzle 4 in this solution to be directly absorbed by the suction head 602, the limiting block 903 in this solution is also provided with a limiting hole 9031, and the limiting hole 9031 is respectively interconnected with the ejection slot hole and the adsorption slot hole. The height of the limiting hole 9031 is higher than the water level height of the cleaning water in the sealed space located at the nozzle 4. With such a setting, the water vapor in the sealed space located at the nozzle 4 can directly float into the sealed space located at the suction head 602 through the limiting hole 9031 and finally be absorbed and collected by the suction head 602.

[0029] In addition, it is also worth noting that, for example, in the case of elastic fabric products such as sofa leather, when the hand-held housing 7 presses such fabric products, the fabric products located in the closed space tend to recover and deform towards the top, and as a result, the fabric products in the closed space will form an arc-shaped structure that bulges towards the top, causing the distance between this part of the fabric products and the hinge ends of the limiting block 903 and the lifting block 1002 to be smaller than the distance between the hinge ends of the limiting block 903 and the lifting block 1002 and the other end of the limiting block 903; and because the limiting block 903 rotates along its hinge end with the lifting block 1002, during the rotation of the limiting block 903, the other end of the limiting block 903 will exert a pushing force on the fabric products in the closed space in the direction of the suction head 602. After the limiting block 903 is vertically arranged, the fabric products in the sealed space in the nozzle 4, due to the action of the pulling force, are transformed from the original arc-shaped structure that bulges towards the top into a horizontal planar structure, making the knitting gaps on the surface layer of the fabric products in the sealed space in the nozzle 4 larger, and thus accelerating the speed at which the cleaning water penetrates into the inner layer of the fabric products.

[0030] According to the description of the above embodiments, when the limiting block 903 rotates, the surface layer of the fabric article in the sealing space of the nozzle 4 is in a horizontal planar structure, while the surface layer of the fabric article in the sealing space of the suction head 602 is still in an arc structure with a top bulge; and such an arc structure is not conducive to the suction head 602 absorbing and collecting the cleaning water and mites in the fabric article. Based on this, this solution needs to ensure that when the suction head 602 contacts the surface layer of the fabric article, the surface part of the fabric article in contact with the suction head 602 is in a planar structure in a stretched state; therefore, this solution further includes a linkage structure 11, and the linkage structure 11 includes a linkage rod 1101, two hinge rods 1102 and a driven block 1103. The top end of the driven block 1103 is hinged to the end face of the handheld housing 7. The suction head 602 is located between the driven block 1103 and the limiting block 903. The two hinge rods 1102 are respectively correspondingly matched with the driven block 1103 and the limiting block 903. Any one of the hinge rods 1102 is arranged on the driven block 1103 or the limiting block 903. The two ends of the linkage rod 1101 are respectively hinged to the two hinge rods 1102. The driven block 1103 and the limiting block 903 are arranged parallel to each other. The driven block 1103, the limiting block 903, the linkage rod 1101 and the handheld housing 7 together form a parallelogram structure; it should be noted that in this embodiment, due to the addition of the structure of the driven block 1103, the closed space of this solution is divided into three sealing spaces in total. The leftmost sealing space is formed by the telescopic block 901 and the driven block 1103 together; the middle sealing space is formed by the driven block 1103 and the limiting block 903 together, and the suction head 602 is located in the middle sealing space; the rightmost sealing space is formed by the limiting block 903 and the telescopic block 901 together, and the nozzle 4 is located in the rightmost sealing space. Through such a setting, when the limiting block 903 rotates, the driven block 1103 will rotate following the rotation of the limiting block 903. Since during the rotation of the driven block 1103, the surface layer of the fabric article in the middle sealing space will be transformed from the original arc state bulging towards the top into a planar structure in a stretched state, so that the surface layers of the fabric articles in the middle sealing space and the rightmost sealing space of this solution are both in a planar structure in a stretched state.

[0031] According to the description of the above embodiments, it can be seen that the normal rotation of the driven block 1103 in this solution relies on the parallelogram structure formed by the driven block 1103, the limiting block 903, the linkage rod 1101, and the handheld housing 7. However, since the limiting block 903 in this solution not only rotates but also moves up and down along the axis direction of the driving slot hole 701, therefore, the driven block 1103 in this solution also needs to have a lifting movement to maintain the parallelogram structure. Based on this, the linkage structure 11 in this solution further includes a driven rod 1104, a driving rod 1105, and a driven spring 1106. The handheld housing 7 is also provided with a driven slot hole, and the driven slot hole is communicated with the telescopic slot hole. The driven rod 1104 is disposed in the driven slot hole in a liftable manner. The lifting direction of the driven rod 1104 is the same as the lifting direction of the lifting block 1002, and the initial height of the driven rod 1104 is the same as the initial height of the lifting block 1002. The driving rod 1105 is disposed in the telescopic slot hole, and both ends of the driving rod 1105 are respectively connected to the telescopic block 901 and the top end of the driven rod 1104. The bottom end of the driven rod 1104 is hinged to the top end of the driven block 1103. Both ends of the driven spring 1106 are respectively connected to the driven rod 1104 and the driven block 1103. The hinged end of the driven rod 1104 and the driven block 1103 is located directly below the driven slot hole. By providing the driven rod 1104, the driven rod 1104 is connected to the driven block 1103, realizing the structure that the driven block 1103 also has a lifting function. Moreover, the hinged end of the driven rod 1104 and the driven block 1103 is located directly below the driven slot hole. Such a setting is consistent with the connection relationship between the lifting block 1002 and the limiting block 903. The movement of the driven block 1103 here is the same as the movement of the limiting block 903, which will not be elaborated here. Through such a setting, the driven block 1103 is always kept in a parallel structural relationship with the limiting block 903.

[0032] It is also worth noting that, in order to ensure that the suction head 602 of this solution can smoothly adsorb and collect the cleaning water and mites in the fabric articles, it is required that the adsorption end of the suction head 602 be attached to the surface of the fabric articles. Based on this, the suction head 602 of this solution can be vertically slidably arranged in the adsorption slot hole, and the suction head 602 can be slidably arranged on the linkage rod 1101 along the axial direction of the linkage rod 1101. The adsorption end of the suction head 602 is located at the bottom of the linkage rod 1101, and the distance between the adsorption end of the suction head 602 and the linkage rod 1101 is equal to the distance between the hinge rod 1102 and the bottom surface of the limiting block 903. It is worth noting that, in order to ensure the normal rotation of the limiting block 903 and the driven block 1103, it is required that there is a certain distance between the hinge rod 1102 arranged on the limiting block 903 and the bottom surface of the limiting block 903. At the same time, it is also required that there is a certain distance between the other hinge rod 1102 on the driven block 1103 and the bottom surface of the driven block 1103, and the distances of both are equal. In addition, in order to ensure the normal movement of the linkage rod 1101, it is required that after the linkage rod 1101 and the two hinge rods 1102 are hinged to each other, the axial direction of the linkage rod 1101 and the hinge point between the lifting block 1002 and the limiting block 903 do not coincide. In addition, the hinge point between the lifting block 1002 and the limiting block 903 and the hinge point between the driven block 1103 and the driven rod 1104 are always on the same horizontal line and parallel to the axis of the linkage rod 1101. By vertically slidably arranging the suction head 602 in the adsorption slot hole and slidably arranging the suction head 602 on the linkage rod 1101 along the axial direction of the linkage rod 1101, when the limiting block 903 rotates towards the bottom, the linked linkage rod 1101 will move downward and translate towards the bottom, thereby realizing that the suction head 602 will descend following the descent of the linkage rod 1101. And the distance between the adsorption end of the suction head 602 and the linkage rod 1101 is equal to the distance between the hinge rod 1102 and the bottom surface of the limiting block 903. Such a setting ensures that after the limiting block 903 rotates to the vertical height, the adsorption end of the suction head 602 is in contact with the surface layer of the fabric article.
