Description

Technical Field

[0001] The present application relates to the technical field of steam cleaning machines, and in particular to a handheld instant hot cleaning machine. Background Art

[0002] Steam cleaners use high-temperature, high-pressure steam to sterilize surfaces, remove dust and bacteria, and effectively clean floors, windows, doors, clothing, range hoods, air conditioners, microwave ovens, and sanitary ware. They are environmentally friendly and hygienic, helping to prevent allergies and remove stubborn stains and oils. No chemicals are required, and the cleaning process is virtually harmless. This allows people to enjoy a hygienic environment without causing secondary pollution.

[0003] Steam cleaning machines need to generate a large amount of heat in a short period of time to heat the water and vaporize it. However, when the heating elements of most steam cleaning machines on the market are heated, some of the heat generated cannot be absorbed by the water and leaks into the outer casing, causing the outer casing to become hot or some electronic components in the cleaning machine to malfunction due to the high temperature inside the outer casing, affecting the normal operation of the equipment. Utility Model Content

[0004] Based on this, it is necessary to provide a handheld instant hot cleaning machine to address the above problems.

[0005] The handheld instant hot washing machine of the present application comprises a housing and a steam generating device arranged in the housing, and a nozzle and a water tank module respectively connected to the steam generating device, wherein the nozzle and the water tank module are respectively arranged on the housing.

[0006] The steam generating device includes a first shell, a second shell, a heating element and a water pump module. The first shell is provided with a heating chamber and an installation chamber separated from each other, and the heating element is installed in the installation chamber.

[0007] The second shell is sleeved on the periphery of the first shell, and the second shell is made of heat-insulating material;

[0008] The water tank module and the water pump module are respectively connected to the second shell surface, and the water tank module, the water pump module, the heating chamber and the nozzle are sequentially connected through a connecting pipe.

[0009] The handheld instant hot cleaning machine disclosed in the present application has a steam generating device comprising a first shell, a second shell, a heating element and a water pump module. The first shell is internally formed with a heating chamber and an installation chamber that are isolated from each other. The installation chamber can be used to install the heating element. The water inlet and outlet of the heating chamber are respectively connected to the water outlet of the water pump module and the water inlet of the nozzle. When the heating element is working, a large amount of heat is generated. The heat is transferred through the shell to heat the water in the heating chamber. Under the action of the water pump module, the water in the water tank module is pumped into the heating chamber for heating and vaporization to generate high-temperature steam. Because the second shell is arranged on the periphery of the first shell and the second shell is made of heat-insulating material, the heat generated by the heating element in the first shell can be reduced from leaking, thereby improving the heating efficiency. In addition, the leaked heat can be reduced from affecting or even damaging other equipment inside the cleaning machine, and the problem of the outer shell being hot can be avoided. In addition, because both the water tank module and the water pump module are connected to the second shell, the use of additional fixing brackets can be reduced, reducing the complexity of the internal structure assembly of the cleaning machine.

[0010] In one embodiment, the heating chamber and the installation chamber are distributed from top to bottom in the first shell, and a plurality of guide plates are provided in the heating chamber. The plurality of guide plates are spaced and staggered along the length direction of the heating chamber to form a maze-shaped flow channel.

[0011] The handheld instant hot cleaning machine in the above embodiment further defines a maze-like flow channel in the heating chamber, which is separated and staggered by multiple guide plates, so that the water entering the heating chamber can extend the residence time of the water in the heating chamber along the flow channel, thereby improving the vaporization efficiency and avoiding dripping or leakage from the nozzle.

[0012] In one embodiment, a filter device is provided in the heating chamber, and a plurality of micropores are provided on the filter device. The filter device is distributed on the circulation channel, and the filter device divides the heating chamber into a first steam bin and a second steam bin. The handheld instant hot cleaning machine in the above embodiment further defines that a filter device is installed in the heating chamber, and the filter device divides the heating chamber into a first steam bin and a second steam bin. Water enters the heating chamber and flows along the circulation channel path, and is first vaporized in the first steam bin. The plurality of micropores on the filter device can break up the water droplets after the first vaporization, and then the broken up water droplets enter the second steam bin for secondary vaporization, thereby improving the vaporization efficiency.

[0013] In one embodiment, the heating element is U-shaped, the installation cavity bulges toward the heating cavity to form a heating step, and the heating step surrounds the inner side wall of the heating cavity.

[0014] The handheld instant thermal cleaning machine in the above embodiment further defines that the installation cavity is raised toward the heating cavity to form a heating step. Based on the above design, the contact area between the water in the heating cavity and the surface of the heating cavity is increased, thereby improving the heat absorption efficiency and thereby improving the vaporization conversion efficiency. In addition, based on the U-shape of the heating element and the heating step surrounding the inner side wall of the heating cavity, combined with the path shape of the circulation channel, the water in the heating cavity can contact the heating step more when being transmitted along the circulation channel.

[0015] In one embodiment, a plurality of fixing members are provided on the second shell, and the plurality of fixing members are distributed at intervals, and the fixing members are used to clamp the connecting pipe.

[0016] The handheld instant hot washing machine in the above embodiment further defines that a plurality of fixing parts for fixing the connecting pipe are provided on the second shell. Based on the above design, the stability of the connecting pipe during the assembly process and the aesthetics of the connecting pipe after assembly with the second shell can be improved.

[0017] In one embodiment, the second shell includes a second upper cover and a second base, the second upper cover and the second base are connected to form an insulating cavity, the first shell is located in the insulating cavity, the second upper cover is provided with a fixed bracket, and the water pump module is connected to the fixed bracket.

[0018] In one embodiment, the second upper cover and the second base are respectively provided with a first screw hole, and the second upper cover and the second base are connected by fixing screws that cooperate with the first screw holes.

[0019] The handheld instant hot cleaning machine in the above embodiment further defines that the second upper cover and the second base are detachably connected by the cooperation of the fixing screws and the first screw holes, so as to facilitate future maintenance of the first shell and the equipment in the heating chamber.

[0020] In one embodiment, the second base and the water tank module are respectively provided with second screw holes, and the second base and the water tank module are connected by fixing screws that cooperate with the second screw holes.

[0021] The handheld instant hot washing machine in the above embodiment further limits the second base and the water tank module to achieve a detachable connection through the cooperation of the second screw hole and the fixing screw, thereby realizing the distribution of the water pump module, the second shell and the water tank module in sequence from top to bottom.

[0022] In one embodiment, one end of the top of the water tank module is recessed to form a mounting step, and the second shell is located on the mounting step.

[0023] The handheld instant hot washing machine in the above embodiment further defines a recessed installation step at one end of the top of the water tank module, and the second shell can be installed on the installation step.

Based on the first through hole, a handle structure is formed on the shell for the user to hold. At the same time, since the handle structure is adjacent to the button module, the user can operate the button module with one hand when holding the handle, thereby providing rationality in the overall design of the washing machine.

[0028] In one embodiment, the outer shell includes a third shell and a fourth shell, and the third shell and the fourth shell are respectively covered on the left and right sides of the water tank module, and the third shell and the fourth shell are detachably connected by fixing screws.

[0041] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0042] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, for the purposes of describing the embodiments of the present application herein.

[0043] like Figures 1 to 6 As shown, this embodiment provides a handheld instant hot washing machine, which includes a housing 10 and a steam generating device 30 disposed in the housing 10, as well as a nozzle 20 and a water tank module 40 respectively connected to the steam generating device 30. The nozzle 20 and the water tank module 40 are respectively disposed on the housing 10.

[0044] The steam generating device 30 includes a first shell 31, a second shell 32, a heating element 33 and a water pump module 34. The first shell 31 defines a heating chamber 301 and an installation chamber 302, which are separated from each other. The heating element 33 is installed in the installation chamber 302.

[0045] The second shell 32 is sleeved on the outer periphery of the first shell 31 and is made of heat-insulating material;

[0046] The water tank module 40 and the water pump module 34 are respectively connected to the surface of the second shell 32. The water tank module 40, the water pump module 34, the heating chamber 301 and the nozzle 20 are connected in sequence through connecting pipes.

[0047] The steam generating device 30 can be used to heat water entering the heating chamber 301 and vaporize it into high-temperature steam. The steam generating device 30 can include a first housing 31 , a second housing 32 , a heating element 33 and a water pump module 34 .

[0048] The first shell 31 can be a metal shell with high thermal conductivity. For example, the first shell 31 is a copper shell structure. A heating chamber 301 and an installation chamber 302 that are isolated from each other can be formed inside the first shell 31. The water inlet and water outlet of the heating chamber 301 are respectively connected to the water outlet of the water pump module 34 and the water inlet of the nozzle 20. Under the action of the water pump module 34, the water to be heated is discharged from the water pump module 34 and enters the heating chamber 301, and then is discharged from the heating chamber 301 to the nozzle 20. The installation chamber 302 can be used to install the heating element 33. The heating element 33 generates a large amount of heat when working. The heat is transferred through the shell to heat the water in the heating chamber 301 and vaporize it.

[0049] The second shell 32 can be a shell structure with high thermal insulation performance, or the interior of the second shell 32 can be covered with thermal insulation material. For example, the interior of the second shell 32 is covered with thermal insulation materials such as foam plastics. Since the second shell 32 is sleeved on the periphery of the first shell 31, the leakage of heat generated by the heating element 33 in the first shell 31 can be reduced, thereby improving the heating efficiency. In addition, the leakage of heat can be reduced to affect or even damage other equipment inside the cleaning machine. It should be noted that the second shell 32 is provided with an opening arranged opposite to the water inlet and water outlet of the first shell 31, and the connecting pipes pass through the corresponding openings and are respectively connected to the water inlet and water outlet of the first shell 31.

[0050] Furthermore, the second housing 32 can provide connection conditions for the water pump module 34, eliminating the need for additional brackets for installation, thereby reducing the complexity of the overall assembly structure.

[0051] The water tank module 40 can be used to load liquids such as water, cleaning liquid, etc. For example, the water tank module 40 is loaded with water, and the water in the water tank module 40 is pumped into the heating chamber 301 by the water pump module 34 for heating.

[0052] The nozzle 20 can be connected to other accessories, such as an extension tube, a glass scraper, a brush head, etc., to meet flexible use in various scenarios.

[0053] In the above-described embodiment of the handheld instant hot cleaning machine, the steam generating device 30 includes a first housing 31, a second housing 32, a heating element 33, and a water pump module 34. The first housing 31 defines a mutually isolated heating chamber 301 and an installation chamber 302. The installation chamber 302 is used to mount the heating element 33. The water inlet and outlet of the heating chamber 301 are connected to the water outlet of the water pump module 34 and the water inlet of the nozzle 20, respectively. When the heating element 33 is in operation, it generates a large amount of heat, which is transferred through the housing to heat the water in the heating chamber 301. Under the action of the water pump module 34, the water in the water tank module 40 is pumped into the heating chamber 301 for heating and vaporization to generate high-temperature steam. Because the second housing 32 is sheathed around the first housing 31 and is made of thermally insulating material, it can reduce the leakage of heat generated by the heating element 33 within the first housing 31, thereby improving heating efficiency. Furthermore, it can reduce the impact or even damage of the leaked heat on other equipment within the cleaning machine, and prevent the outer shell 10 from becoming too hot to touch. In addition, since both the water tank module 40 and the water pump module 34 are connected to the second shell 32, the use of additional fixing brackets 3211 can be reduced, thereby reducing the complexity of the internal structure assembly of the cleaning machine.

[0054] like Figure 2 、 Figure 3 and Figure 6 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the heating chamber 301 and the installation chamber 302 are distributed from top to bottom in the first shell 31, and a plurality of guide plates 35 are provided in the heating chamber 301. The plurality of guide plates 35 are spaced and staggered along the length direction of the heating chamber 301 to form a maze-like circulation channel.

[0055] The above embodiment further defines that a maze-like flow channel is formed in the heating chamber 301 by a plurality of guide plates 35 spaced and staggered, so that the water entering the heating chamber 301 can extend the residence time of the water in the heating chamber 301 along the flow channel, thereby improving the vaporization efficiency and avoiding dripping or leakage from the nozzle 20.

[0056] Among them, a plurality of guide plates 35 are provided in the heating chamber 301. Based on the plurality of guide plates 35 being arranged in an intermittent and staggered manner, a maze-like flow channel is formed in the heating chamber 301. Exemplarily, the number of guide plates 35 is five, and the five guide plates 35 are arranged in sequence from the water inlet of the second shell 32 to the water outlet. Specifically, the first guide plate 35 is close to the water inlet of the second shell 32, and the first guide plate 35 forms two gaps with the wall of the heating chamber 301 respectively. Then, the second guide plate 35 and the third guide plate 35 are symmetrically distributed at the same horizontal position, and a gap is formed between the second guide plate 35 and the third guide plate 35. Then, the fourth guide plate 35 and the fifth guide plate 35 are spaced and distributed on the left and right sides of the wall of the heating chamber 301 respectively, and the fourth guide plate 35 and the fifth guide plate 35 form a gap with the wall of the heating chamber 301 respectively. As Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further defines: a filter device 36 is provided in the heating chamber 301, a plurality of micropores are opened on the filter device, the filter device 36 is distributed on the flow channel, and the filter device 36 separates the heating chamber into a first steam bin and a second steam bin.

[0057] The above embodiment further defines that a filter device 36 is installed in the heating chamber 301, and the filter device 36 divides the heating chamber 301 into a first steam bin and a second steam bin. Water enters the heating chamber 301 and flows along the flow channel path, and is first vaporized in the first steam bin. The multiple micropores on the filter device 36 can break up the water droplets after the first vaporization, and then the broken up water droplets enter the second steam bin for secondary vaporization, thereby improving the vaporization efficiency.

[0058] Among them, the filter device 36 is a high-temperature resistant metal plate shell structure. A plurality of micropores distributed in compartments are provided on the plate shell. After the first vaporization is completed, the larger water droplets are broken up into smaller water droplets after passing through the plurality of micropores. In addition, the filter device 36 and the guide plate 35 are detachably connected. Specifically, the second guide plate 35 and the third guide plate 35 are respectively provided with a card slot 307, and the two ends of the filter device 36 can be fixed on the card slot 307 respectively. It should be noted that the first shell 31 can be composed of a first upper cover 311 and a first base 312 connected together. The first upper cover 311 and the first base 312 enclose a heating chamber 301, and the first upper cover 311 and the first base 312 are detachably connected to facilitate the replacement of the filter device 36 or the cleaning of the circulation channel.

[0059] like Figure 6 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the heating element 33 is U-shaped, the installation cavity 302 bulges toward the heating cavity 301 to form a heating step, and the heating step surrounds the inner wall of the heating cavity 301.

[0060] In the above embodiment, it is further defined that the installation cavity 302 bulges toward the heating cavity 301 to form a heating step. Based on the above design, the contact area between the water in the heating cavity 301 and the surface of the heating cavity 301 is increased, thereby improving the heat absorption efficiency and thereby improving the vaporization conversion efficiency. In addition, based on the U-shape of the heating element 33 and the heating step surrounding the inner wall of the heating cavity 301, combined with the path shape of the circulation channel, the water in the heating cavity 301 can contact the heating step more when being transmitted along the circulation channel.

Based on the above design, the stability of the connecting pipe during the assembly process and the aesthetics of the connecting pipe after assembly with the second shell 32 can be improved.

[0063] The fixing member 323 can be used to secure the connecting pipe. The fixing member 323 can be an L-shaped buckle. The distance between the L-shaped buckle and the surface of the second housing 32 is slightly larger than the diameter of the connecting pipe. The L-shaped buckle can secure the connecting pipe to the second housing 32, improving the stability of the connecting pipe during assembly and the aesthetics of the connecting pipe after assembly. It should be noted that the fixing member 323 can also be a C-shaped buckle, a threading hole, or other structures.

[0064] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further defines: the second shell 32 includes a second upper cover 321 and a second base 322, the second upper cover 321 and the second base 322 are connected to form an insulating cavity, the first shell 31 is located in the insulating cavity, the second upper cover 321 is provided with a fixed bracket 3211, and the water pump module 34 is connected to the fixed bracket 3211.

[0065] The fixing bracket 3211 can be used to mount the water pump module 34. Specifically, the fixing bracket 3211 and the water pump module 34 can be fixed together using fixing screws. Furthermore, the fixing bracket 3211 and the second upper cover 321 are integrally formed, which not only reduces the number of assembly steps but also improves the connection strength between the water pump module 34 and the second upper cover 321, eliminating the need for additional brackets.

[0066] In addition to the features of the above embodiment, this embodiment further defines that: the second upper cover 321 and the second base 322 are respectively provided with first screw holes, and the second upper cover 321 and the second base 322 are connected by fixing screws that cooperate with the first screw holes.

[0067] The above embodiment further defines that the second upper cover 321 and the second base 322 are detachably connected by the cooperation of the fixing screws and the first screw holes, so as to facilitate the maintenance of the first shell 31 and the equipment in the heating chamber 301 in the future.

[0071] The above embodiment further defines that one end of the top of the water tank module 40 is recessed to form an installation step 401, and the second shell 32 can be installed on the installation step 401. On the basis of compressing the product volume, not only the water storage capacity of the water tank module 40 is increased as much as possible to increase the endurance, but also the rationality of the spatial layout is improved, making the cleaning machine smaller and more convenient to hold.

[0072] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the handheld instant thermal cleaning machine also includes a control device 50, the control device 50 includes a circuit board 51 and a key module 52, the circuit board 51 is electrically connected to the key module 52, the heating element 33 and the water pump module 34 respectively, and the circuit board 51 and the key module 52 are distributed at the top of the shell 10.
