Description

Technical Field

[0001] The invention relates to the technical field of ironing equipment, and in particular to a dirt suction and stain removal equipment. Background Art

[0002] During the storage of clothes or fabrics in the warehouse, due to the changes in air temperature and humidity, it is easy for the clothes or fabrics to grow mold, turn yellow, or produce other stains. Therefore, when making or ironing clothes, special potions are often needed to remove stains on the fabrics or clothes. However, the existing way to remove stains is usually to first heat the potion in a constant temperature box, then absorb it with a dropper and then drop it on the stain to clean the stains on the fabrics or clothes. This operation is too cumbersome, inefficient, and prone to misoperation such as dripping too much or too little. It is extremely inconvenient to use and has a low degree of intelligence. In addition, after the potion is absorbed with a dropper, the temperature of the potion will decrease, the stain removal effect is not ideal, and repeated operations are required, which wastes the potion and may damage the fabric. Moreover, during the use of the existing sewage suction equipment, the sewage after the suction is directly discharged, resulting in a waste of potion and a serious impact on the environment.

[0003] Therefore the prior art still needs to be improved and enhanced. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a dirt suction and stain removal device that can circulate the medicine and maintain a constant temperature to achieve a better decontamination effect. After the dirt is sucked, the sewage can also be separated from the water vapor and collected.

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] It should be noted that when a component is referred to as being "mounted on", "fixed on" or "disposed on" another component, it may be directly on the other component or there may be a central component at the same time. When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be a central component at the same time.

[0028] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of the present invention are merely relative concepts or are based on the normal use status of the product and should not be considered as restrictive.

[0029] See also Figure 1 and Figure 2 The dirt suction and stain removal device provided by the present invention comprises a dirt suction platform 100, on which a dirt suction device 8 is arranged, and on which a dirt suction platform 100 is also arranged a dirt circulation constant temperature system 10 for keeping the dirt removal solution constant temperature and circulating, and a water vapor separation device 9 for separating and recycling the sewage sucked by the dirt suction device 8, wherein the water vapor separation device 9 is connected to the dirt suction device 8, and the liquid outlet of the dirt circulation constant temperature system 10 is located above the dirt suction device 8. When the clothes or fabrics are subjected to dirt removal treatment, the dirt is first sprayed with liquid to decompose the dirt by the dirt circulation constant temperature system 10, and then the dirt and the dirt are sucked into the water vapor separation device 9 by the dirt suction device 8. The air, the dirt solution, and the water vapor evaporated from the dirt solution sucked in during the dirt suction process are converted into liquid by the water vapor separation device 9, so that the gaseous dirt solution is separated from the air, and the air is discharged, so that the dirt solution can be collected for recycling, which greatly reduces the cost of the dirt solution. Furthermore, the medicine circulation constant temperature system 10 is used to keep the medicine at an optimal decontamination temperature to achieve a better decontamination effect.

[0030] The water vapor separation device 9 includes a water vapor separation tank 91, a medicine recovery box 92, an electric ball valve 93 and a control box 94. The medicine recovery box 92 is connected to the drain port of the water vapor separation tank 91. The electric ball valve 93 is arranged at the drain port 913 of the water vapor separation tank 91. The electric ball valve 93 is electrically connected to the control box 94. The electric ball valve 93 is used to drain the liquid in the water vapor separation tank 91 into the medicine recovery box 92.

[0031] In this embodiment, the control box 94 has an automatic opening function. Every time the dirt suction and stain removal device is turned on, the electric ball valve 93 is controlled to automatically open for 30 seconds to drain the residual medicine in the water vapor separation tank 91 to avoid excessive medicine inside the water vapor separator, resulting in the ineffective separation of medicine.

[0032] Please continue reading Figure 1 and Figure 2The dirt suction device 8 includes a dirt suction arm 81, a fan 82 and a control member 83. The control member 83 is electrically connected to the fan 82. The fan 82 is connected to the dirt suction arm 81 through a pipeline. The water vapor separation tank 91 is arranged on the pipeline. In use, the fan 82 is controlled to be turned on and off by the control member 83. When dirt suction is required, the fan 82 is controlled to be turned on by the control member 83, and the air suction holes at the dirt suction arm 81 are controlled to suck air, so that the medicine liquid and the stains are sucked into the dirt suction arm 81 together, and then enter the water vapor separation tank 91 through the dirt suction arm 81. The water vapor separation treatment is carried out in the water vapor separation tank 91 to separate the gaseous and liquid medicine liquid from the air. The fan 82 is a vortex high-pressure air pump with a strong air suction function.

[0033] Furthermore, a pressure relief valve 84 and a muffler 85 are also provided at the fan 82. The pressure relief valve 84 can prevent the fan 82 from being damaged due to excessive pressure, thereby extending the service life of the fan 82. The muffler 85 can also reduce the noise of the fan 82, creating a better working environment and reducing noise pollution.

[0034] In this embodiment, the control element 83 is a foot switch, so that the hands and feet of the staff can operate different components separately, which is more convenient for the staff to operate. For example, when it is necessary to suck dirt, the foot steps on the control element 83 to turn on the fan 82, and at the same time, the liquid medicine circulation constant temperature system is controlled by hand to spray liquid medicine on the fabric to decompose the stains, and the stains are sucked at the same time, avoiding the inconvenience caused by both being controlled by hand, which greatly improves the work efficiency.

[0035] Please also read Figure 3 The control box 94 includes a DC switching power supply 941, a DC24V AC contactor 942, a relay 943 and an indicator LED. The live wire and the neutral wire (power plug) of the AC mains are connected to the A1, A2 and A3 terminals of the DC24V AC contactor 942 through a double-pole double-throw switch. T1 and T2 of the DC24V AC contactor 942 are connected to one end of the fan 82, and the T3 terminal is connected to the other end of the fan 82. The power supply end of the DC24V AC contactor 942 is connected to the 5th pin of the relay 943 through the control component 83. The 5th and 6th pins of the relay 943 are connected to the electric ball valve 93. The 2nd pin of the relay 943 is grounded, and the 7th pin is connected to the output end of the DC switching power supply 941. The first AC input terminal of the DC switching power supply 941 is connected to the live wire of the power supply and the A1 and A2 terminals of the DC24V AC contactor 942. The second AC input terminal of the DC switching power supply 941 is connected to the neutral wire of the power supply and the A2 terminal of the DC24V AC contactor 942.

[0036] The DC switch power supply 941 is used to convert the 220V AC voltage into a 24V DC voltage. When the foot switch (i.e., the control element 83) is stepped on, the DC24V AC contactor 942 starts the fan 82 to suck air and dirt. The relay 943 is a time relay that controls the opening time of the electric ball valve 93. When the opening time is reached, the relay 943 controls the electric ball valve 93 to close.

[0037] Please also read Figure 4 and Figure 5 A water vapor separator 912 is arranged in the water vapor separation tank 91, and the water vapor separator 912 includes a spiral guide plate 9121, an air guide channel 9122, a water baffle 9123 and a filter screen 9124, the water baffle 9123 is arranged at the steam inlet end of the air guide channel 9122, the filter screen 9124 is arranged at the steam outlet end of the air guide channel 9122, the spiral guide plate 9121 is arranged on the outside of the air guide channel 9122, and an air guide port 9125 is also arranged on the air guide channel 9122. The water vapor separation tank 91 is provided with an air inlet 901 connected to the dirt suction arm 81 and an air outlet 902 connected to the fan 82, and the air guide port 9125 is communicated with the air outlet 902.

[0038] Specifically, the air inlet 901 is connected to the liquid outlet of the dirt suction arm 81, so that the air and medicine sucked by the dirt suction arm 81 enter the water vapor separation tank 91, and the air, vaporous medicine and liquid medicine are introduced downward through the spiral guide plate 9121, and the vaporous medicine in the air is condensed to perform the first water vapor separation. By utilizing the principle of gas rising, when the mixture of air and vaporous medicine enters the air guide channel 9122, the gaseous medicine is further condensed through the water baffle 9123, and the gaseous medicine is separated from the air, which plays the role of the second water vapor separation. When the gas mixture enters the air guide channel 9122 through the air guide port 9125, it then passes through the filter net 9124 to perform the role of the third water vapor separation. Finally, the filtered air is discharged through the air outlet 902, and the separated medicine is deposited in the water vapor separation tank 91.

[0039] Please continue reading Figure 4 and Figure 5 The air inlet 901 is located at the upper part of the spiral guide plate 9121, and the air outlet 902 is arranged at the upper part of the filter screen 9124, so that after the medicine and the air are separated by the spiral guide plate, the medicine is retained in the water vapor separation tank 91, and the air is discharged through the air outlet 902. In this embodiment, the filter screen 9124 is arranged obliquely on the upper side of the air inlet 901 and the lower side of the air outlet 902, which is conducive to air output.

[0040] Furthermore, a partition 9126 for sealing the air guide channel 9122 and the water vapor separation tank 91 is provided at the top of the air guide channel 9122, so that the air in the water vapor separation tank 91 must pass through the air guide channel 9122 and the filter 9124 to be discharged, thereby ensuring that there is no water vapor in the air discharged through the air outlet 902, and will not cause waste of medicine and air pollution.

[0041] Please continue reading Figure 4 and Figure 5 A drain port 913 is provided at the bottom of the water vapor separation tank 91, and the electric ball valve 93 is provided at the drain port 913. By opening the electric ball valve 93, the medicine separated by the water vapor separation tank 91 enters the recovery box through the drain valve.

[0042] Please also read Figure 6 and Figure 7 The medicine circulation constant temperature system 10 is located on one side of the sewage suction platform 100, and includes a constant temperature medicine storage device 1, an infusion pump 2, a liquid outlet pipe 3, a liquid outlet piece 4, and a liquid return pipe 5. The constant temperature medicine storage device 1, the liquid outlet pipe 3, the liquid outlet piece 4, and the liquid return pipe 5 are sequentially connected to form a circulation loop. When the liquid outlet piece 4 is opened, the medicine in the constant temperature medicine storage device 1 is pumped into the liquid outlet pipe 3 by the infusion pump 2 and is led out through the liquid outlet piece 4. When the liquid outlet piece 4 is closed, the infusion pump 2 allows the medicine to flow back to the constant temperature medicine storage device 1 through the liquid return pipe 5. The liquid outlet piece 4 is located above the sewage suction arm 81, which is more convenient for the staff to operate. When in use, the medicine in the constant temperature medicine storage device 1 can be discharged through the liquid outlet 4 when needed, and circulated when not needed, so that the temperature of the medicine in the liquid outlet pipe 3 and the constant temperature medicine storage device 1 is more uniform, thereby ensuring that no matter when the liquid outlet 4 is opened, the temperature of the discharged medicine is always the temperature required for stain removal, thereby achieving the best stain removal effect.

[0043] The constant temperature medicine storage device 1 comprises a medicine liquid tank 11, a water tank 12 and a constant temperature component 13 for controlling the temperature of the medicine liquid. The medicine liquid tank 11 and the constant temperature component 13 are arranged in the water tank 12. Specifically, the bottom and four side walls of the medicine liquid tank 11 are all located in the hot water in the water tank 12, and the constant temperature component 13 is arranged between the water tank 12 and the medicine liquid tank 11 (such as Figure 7 As shown), by heating the water in the water storage tank 12, the medicine liquid tank 11 placed in the hot water is heated, and combined with the circulation of the medicine liquid, the medicine liquid can be evenly heated.

[0044] In this embodiment, the thermostatic component 13 is not in direct contact with the medicine in the medicine tank 11 under the premise of uniformly heating the medicine by means of water insulation heating, so as to avoid the thermostatic component 13 directly heating the medicine to cause the quality change of the medicine and affect the decontamination effect. Furthermore, an insulation box 7 is also provided outside the water storage tank 12 to play the role of heat preservation and scalding prevention, so as to reduce the energy consumption of the thermostatic component 13 and prevent scalding of the staff.

[0045] The thermostatic assembly 13 includes a heating tube 131, a temperature detector (not shown in the figure) and a controller (not shown in the figure). The heating tube 131 and the temperature detector are both electrically connected to the controller. The temperature detector detects the water in the water tank 12, and the controller controls the heating tube 131 to heat the water to a preset temperature, so as to ensure that the water in the water tank 12 is within a preset temperature range, thereby achieving the purpose of constant temperature heating. Since the thermostatic assembly 13 is a prior art, it will not be described in detail here.

[0046] The medicine circulation constant temperature system 10 also includes a control switch 1331, a temperature regulator 1332 and a display screen 1333. The control switch 1331, the temperature regulator 1332 and the display screen 1333 are electrically connected to the controller. The heating temperature of the heating tube 131 is set by the temperature regulator 1332, and the real-time temperature is displayed by the display screen 1333, so that the staff can observe the temperature of the medicine more intuitively, which is convenient for operation. Among them, the controller can adopt a PIC16F18456T microprocessor, and the controller has rich IO ports (input and output ports) and good scalability. The heating tube 131, the temperature detector, the control switch 1331, the temperature regulator 1332, the display screen 1333, etc. can all be connected to an IO port of the controller. Of course, other models of controllers can also be used, such as Siemens S7-200 PLC controller, etc. This is a prior art and will not be repeated here.

[0047] Please continue reading Figure 1 and Figure 2 The liquid medicine tank 11 is provided with a first liquid level detector 111 to prevent the liquid medicine in the liquid medicine tank 11 from being too low, so that the liquid outlet 4 does not have any liquid medicine or the amount of water discharged is small, so as to avoid affecting the decontamination effect. Furthermore, a liquid medicine supply device (not shown in the figure) can be provided to be connected to the liquid medicine tank 11 to realize the function of automatically adding liquid medicine. Of course, an alarm device (not shown in the figure) can also be provided to be connected to the first liquid level detector 111 to sound an alarm when the liquid medicine is too low, prompting the staff to add liquid. Both of these liquid adding methods are acceptable and can be selected according to actual needs.

[0048] The water tank 12 is provided with a second liquid level detector 121 to ensure the liquid level in the water tank 12 and prevent the heating tube 131 from being damaged due to dry burning. The water tank 12 can also be provided with a water supply device (not shown in the figure) connected thereto to achieve automatic water supply, or an alarm device (not shown in the figure) can be used to prompt the staff to add liquid. The liquid adding method is the same as the liquid adding method of the liquid tank 11, and can be selected according to needs.

[0049] Specifically, in this embodiment, both the first liquid level detector 111 and the second liquid level detector 121 can adopt a reed switch with an alarm function, which is a prior art and will not be described in detail here.

[0050] Among them, a two-position three-way solenoid valve 6 is provided at the liquid outlet 4, and the return liquid pipe 5 is connected to the normally open end of the two-position three-way solenoid valve 6. When the liquid outlet 4 is opened, the medicine in the medicine liquid tank 11 is pumped to the liquid outlet pipe 3 and the two-position three-way solenoid valve 6 through the infusion pump 2, and then discharged through the liquid outlet 4; when the liquid outlet 4 is closed, the medicine in the medicine liquid tank 11 is pumped to the liquid outlet pipe 3 and the two-position three-way solenoid valve 6 through the infusion pump 2, and then flows back to the medicine liquid tank 11 through the return liquid pipe 5, so that the medicine in the medicine liquid tank 11 can be discharged at any time when needed, and can be automatically circulated when not needed to ensure the temperature of the discharged medicine.

[0051] In this embodiment, the infusion pump 2 is a peristaltic pump, which has the advantages of no pollution, long life, and easy maintenance. It can also reduce the number of infusion pumps 2 used in the medicine circulation constant temperature system 10 to reduce equipment costs.

[0052] The liquid outlet member 4 is a spray gun, and a liquid outlet switch (not numbered in the figure) is provided on the spray gun, which is easy to use. Moreover, the liquid medicine is sprayed out at a certain pressure through the spray gun, thereby achieving a better decontamination effect.

[0053] The dirt suction platform 100 is provided with a bracket 101, and the liquid outlet 4 is arranged on the bracket 101 in a manner that it can be raised and lowered. Specifically, the bracket 101 is provided with a retractable pull rope 102, so that the liquid outlet 4 can be retracted and moved freely, so as to facilitate the operation of the staff. The bracket 101 is also provided with a light tube 103 to ensure the brightness of the dirt suction platform 100, to facilitate the observation of stains, and to ensure the cleanliness of clothes or fabrics.

[0054] In summary, the dirt suction and stain removal device provided by the present invention, when performing a dirt removal treatment on clothing or fabric, first sprays liquid on the stain through the medicine circulation constant temperature system, and then sucks the stain and the medicine into the water vapor separation device through the dirt suction device. The air sucked in during the dirt suction process is separated from the medicine by the water vapor separation device, and the air is discharged, so that the medicine can be recycled, which greatly reduces the cost of the medicine. Furthermore, the medicine circulation constant temperature system is used to keep the medicine at the optimal decontamination temperature to achieve a better decontamination effect.

[0055] In addition, the present invention has the characteristics of simple structure, easy operation and the like.
