Balanced pressure tank for a cleaner

Abstract

This invention relates to the field of cleaning technology and discloses a balanced pressure water tank for a cleaner, comprising a tank body and a pressure release mechanism disposed within the tank body. The pressure release mechanism includes a water-air separation component and a release component connected to and communicating with the outside of the tank body. The water-air separation component includes a water-air separation body and an inlet and an outlet disposed within the water-air separation body, as well as a first water-air separation channel communicating with the inlet and outlet. This first water-air separation channel has multiple separation chambers. Because the water-air separation component generates multiple eddies in the liquid along the separation direction through the first water-air separation channel, it affects the liquid flow in the separation direction but does not affect the passage of gas. Therefore, water and gas can be separated, and the separated gas is discharged to the outside of the tank body through the release component, effectively and slowly releasing the pressure generated inside the tank during the cleaning process, thus balancing the pressure inside and outside the tank.

Description

Technical Field

[0001] This invention relates to the field of cleaner technology, and more particularly to a balanced pressure water tank for cleaners. Background Technology

[0002] Cleaners typically require continuous scrubbing of surfaces to achieve high cleaning efficiency. However, when using scrubbing rollers, which are usually made of sponge, the wastewater is collected after squeezing the rollers, and the squeezed-out air is also collected, causing an increase in pressure within the collection chamber. Effectively releasing this pressure becomes a problem that needs to be solved. Summary of the Invention

[0003] The main technical problem solved by this invention is to provide a balanced pressure water tank for a cleaner, which can effectively and slowly release the pressure generated inside the water tank during the cleaning process, so as to balance the pressure inside and outside the water tank.

[0004] To solve the above-mentioned technical problems, the present invention provides a balanced pressure water tank for a cleaner, including a water tank body and a pressure release mechanism disposed within the water tank body. The pressure release mechanism includes a water-air separation component and a release component connected to and communicating with the outside of the water tank body. The water-air separation component includes a water-air separation body and a separation inlet and a separation outlet disposed within the water-air separation body, as well as a first water-air separation channel communicating with the separation inlet and the separation outlet. The first water-air separation channel is provided with multiple separation chambers.

[0005] Furthermore, the first water-air separation channel includes multiple separation chambers on both sides, with each separation chamber on the same side connected to each other, and the separation chambers on both sides being staggered.

[0006] Furthermore, each of the separation chambers is provided with an inclined surface that is perpendicular to the pressure release direction.

[0007] Furthermore, each of the separation chambers is equipped with a baffle plate, and each baffle plate divides the first separation chamber into an air path and a vortex branch.

[0008] Furthermore, a baffle is provided between two adjacent separation chambers.

[0009] Furthermore, the baffle plate forms a 30-degree angle with the first water-air separation channel.

[0010] Furthermore, the water-gas separation assembly also includes a second water-gas separation channel located at the connection between the water-gas separation body and the first water-gas separation channel, and the second water-gas separation channel is provided with multiple turbulence chambers.

[0011] Furthermore, the second water-gas separation channel is arranged in parallel with the first water-gas separation channel.

[0012] Furthermore, the second water-air separation channel includes a vortex cavity and a second baffle plate disposed opposite to the vortex cavity to change the direction of liquid flow.

[0013] Furthermore, the second spoiler is arc-shaped along the direction of water-air separation.

[0014] Furthermore, the second water-gas separation channel is parallel to the first water-gas separation channel as a whole, and it consists of multiple curved turbulence sections.

[0015] Furthermore, the pressure relief mechanism also includes a balance channel that runs through the water-gas separation body. The balance channel is parallel to the first water-gas separation channel and is composed of multiple curved turbulence sections.

[0016] Furthermore, the separation inlet and separation outlet are located at the same end of the water-gas separation body.

[0017] Furthermore, the separation inlet and separation outlet are located at opposite ends of the water-gas separation body.

[0018] Furthermore, the release assembly includes a pipe with one end connected to the water-air separation assembly and the other end connected to a pressure relief component. The pressure relief component has a pressure relief chamber and a pressure relief opening. The pressure relief opening has two elastic plates, and there is an opening between the elastic plates that remains closed when no pressure is released.

[0019] To elaborate further, the two elastic sheets are set at an angle, and the gap between the two elastic sheets gradually decreases from the outside to the inside, and they contact each other at the ends.

[0020] To elaborate further, the opening is elongated.

[0021] This invention relates to a balanced pressure water tank for a cleaner, comprising a tank body and a pressure release mechanism disposed within the tank body. The pressure release mechanism includes a water-air separation component and a release component connected to and communicating with the outside of the tank body. The water-air separation component includes a water-air separation body, a separation inlet and a separation outlet disposed within the water-air separation body, and a first water-air separation channel communicating with the separation inlet and the separation outlet. This first water-air separation channel has multiple separation chambers. Because the water-air separation component generates multiple eddies in the liquid along the separation direction through the first water-air separation channel, it affects the liquid flow in the separation direction but does not affect the passage of gas. Therefore, water and gas can be separated, and the separated gas is discharged to the outside of the tank body through the release component, effectively and slowly releasing the pressure generated inside the tank during the cleaning process, thus balancing the pressure inside and outside the tank.

[0052] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0053] like Figures 1-10 As shown, the present invention provides an embodiment of a balanced pressure water tank for a cleaner.

[0054] The cleaner uses a balanced pressure water tank, which includes a balanced pressure water tank 1. The balanced pressure water tank includes a water tank body 20 and a water inlet / outlet mechanism 10 that is connected to a storage cavity after the water tank body 20 is pressurized. It also includes a pressure release mechanism 30 that is located inside the water tank body to maintain the water tank pressure balance. The pressure release mechanism 30 includes a water-air separation component 303 and a release component 301 that is connected to the water-air separation component 303 and communicates with the outside of the water tank body. The water-air separation component 303 includes a water-air separation body 3030 and a separation inlet 3032 and a separation outlet 3031 located in the water-air separation body 3030. It also includes a first water-air separation channel A that communicates with the separation inlet 3032 and the separation outlet 3031. The first water-air separation channel A is provided with a plurality of first separation chambers 3036.

[0055] Specifically, the cleaner's balanced pressure water tank includes other structures. Other undescribed structures can be implemented using existing technologies, and these structures are not improvements of this invention, so they will not be described in detail here.

[0056] Specifically, such as Figure 1 , Figure 4 As shown, the water inlet / outlet mechanism 10 includes a mounting base 104 and a fixed base 101 disposed within the mounting base 104. The fixed base 101 is respectively provided with a clean water output component 102 that forms a clean water output channel when pressed and a sewage inlet component 103 that forms a sewage input channel when pressed. The clean water output component 102 includes an inlet / outlet pin structure (not shown in the figure) that mates with a through hole (not shown in the figure) on the fixed base 101, a pressure spring (not shown in the figure) that causes the outlet pin structure to extend, and a limiting component or structure (not shown in the figure) that limits the extension position of the inlet / outlet pin structure. When the inlet / outlet pin structure is pressed and moved, the inlet / outlet pin structure and the through hole form a clean water channel (not shown in the figure). The structure of the sewage inlet component 103 is the same as that of the clean water outlet component 102, namely, it includes an inlet / outlet pin structure (not shown in the figure) that mates with the through hole (not shown in the figure) on the fixed base 101, a pressure spring that makes the inlet / outlet pin structure tend to extend, and a limiting component or structure that limits the extension position of the inlet / outlet pin structure. When the inlet / outlet pin structure is pressed and moved, the inlet / outlet pin structure and the through hole form a sewage channel (not shown in the figure).

[0057] Specifically, such as Figure 1 , Figure 4As shown, the clean water output component 102 and the wastewater inlet component 103 of the water inlet / outlet mechanism 10 are elastically clamped between the fixed base 101 and the mounting base 104. One end of the outlet pressure spring abuts against the outlet pin and the other end abuts against the mounting base 104. One end of the return pressure spring abuts against the return pin and the other end abuts against the mounting base 104. The fixed base 101 has openings at both ends. The end with the larger opening has an outwardly expanding snap-fit ​​interface edge with a certain strength and thickness (not shown in the figure). The end with the smaller opening is fitted into the inner part of the mounting base 104. On the wall, the fixing seat 101 has a partition (not shown in the figure) on the side near the large opening end to block the opening. The partition has a conical through hole (not shown in the figure) that abuts against the water outlet pin and the water return pin. A sealing gasket (not shown in the figure) is sandwiched between the small opening end face of the fixing seat 101 and the inner bottom wall of the mounting seat 104. The sealing gasket is made of elastic material. After the fixing seat 101 and the mounting seat 104 are detachably connected by fastening screws, the elastic sealing gasket can fill the gap between them to effectively prevent leakage. The outer walls of the large and small openings of the interface connector 101 maintain two different outer diameters. The outer wall of the fixing seat 101 must be provided with a step (not shown in the figure) that divides the large and small openings. The lower part of the snap-fit ​​edge of the large opening of the fixing seat 101 extends to the step and is fitted with a sealing ring (not shown in the figure). The sealing ring can seal the gap between the water inlet / outlet mechanism 10 and the water tank body 20 after they are snapped together. The mounting base 104 is open at one end, with the fixed base 101 fitted onto the open end, and closed at the other end. However, a through hole (not shown in the figure) is provided on the closed end face of the mounting base 104, which communicates with the clean water output component 102 and the sewage inlet component 103. A water suction pipe interface (not shown in the figure) extends outward from the through hole of the clean water output component 102 on the closed end face of the mounting base 104. A filter component connection port (not shown in the figure) extends outward from the closed end face of the mounting base 104 around the water suction pipe interface. The inner wall of the filter component connection port is threaded (not shown in the figure). The inner thread is coupled and detachably connected to the outer thread (not shown in the figure) of the filter component connection port at the open end of a cylindrical filter component 40. The filter component 40 has multiple hollow structures (not shown in the figure) on its peripheral wall and bottom wall, and its outer surface is covered with a filter screen (not shown in the figure). A suction pipe 106 is fitted onto the suction pipe interface. The suction pipe 106 extends to a region close to the bottom wall of the filter assembly 40. This allows the water filtered in the filter assembly 40 within the cleaner's pressure-balancing water tank 1 to still be drawn in by the suction pipe 106 when the water inlet / outlet mechanism 10 is facing upwards. This drawable state is maintained until the water level of the filtered water in the filter assembly 40 is lower than the lowest opening of the suction pipe 106 (not shown in the figure).

[0058] Specifically, such as Figures 1 to 3 As shown, the water tank body 20 includes an upper water tank body 201 and a lower water tank body 202, which are sealed together. One side of the lower water tank body, extending upwards from its bottom, is a slope (not shown in the attached diagram). The top of this slope, opposite the water inlet / outlet mechanism 10, has a concave locking portion 2021 for easy installation and fixing. This locking portion has a concave locking groove 2022. When fixing the pressure-balancing water tank 1 for the cleaner, the corresponding buckle on the cleaner can engage with the locking groove 2022 of the locking portion 2021. To remove the pressure-balancing water tank 1, simply release the corresponding buckle.

[0059] As a further improved implementation, the upper body and lower body of the water tank are sealed together by an ultrasonic welding layer (not shown in the figure).

[0060] As a further improved implementation, the upper body and lower body of the water tank are sealed together through a secondary injection molding process.

[0061] As a further improved implementation, the upper body and lower body of the water tank are sealed together by a direct bonding process.

[0062] like Figures 3-10 As shown, the water-air separation component 303 is used to separate liquid from air, wherein the liquid includes water, etc.

[0063] like Figure 5 , Figure 6 As shown, first separation chambers 3036 are respectively provided on both sides of the first water-gas separation channel A. That is, the first water-gas separation channel A includes multiple first separation chambers 3036 on both sides, with each separation chamber on the same side connected to each other, and the first separation chambers 3036 on opposite sides staggered. Each first separation chamber 3036 is provided with an inclined surface 3040 at a certain angle to the pressure release direction, so that the distance between two staggered and opposite first separation chambers 3036 gradually increases in the water-gas separation direction, which facilitates the formation of vortices in the two first separation chambers and has a hindering effect on liquid flow.

[0064] To better influence liquid flow in the direction of water-gas separation without affecting gas flow, a first baffle 3035 can be provided in the first separation chamber 3036. Each first baffle 3035 divides the first separation chamber 3036 into a gas path (not shown in the attached figure) and a vortex branch 3037. The vortex branch 3037 generates a turbulent vortex for liquid flow, while gas passes through normally.

[0065] As a feasible implementation method, in order to better form multiple intersecting turbulent vortices in the first water-gas separation channel A, each first turbulence plate is at a 30-degree angle to the water-gas separation channel.

[0066] like Figure 5 , Figure 6 As shown, the bottom of each first separation chamber 3036 is designed with an arc-shaped surface to facilitate vortex formation. Simultaneously, a baffle 3041 is provided in each first separation chamber 3036. This baffle 3041 is located between two adjacent first separation chambers 3036, specifically the bottom of the upper first separation chamber 3036 and the opening of the lower first separation chamber 3036. This allows the turbulent vortex formed in the upper first separation chamber 3036 to affect the flow of liquid entering the opening of the lower first separation chamber 3036, thereby preventing or reducing liquid movement along the water-air channel. Therefore, the longer the first water-air separation channel A of the water-air separation assembly 303 with this structure, the better the separation effect.

[0067] like Figure 5 , Figure 6 As shown, the water-gas separation assembly 303 further includes a second water-gas separation channel B connected to the first water-gas separation channel A within the water-gas separation body 3030. The second water-gas separation channel B has multiple second separation chambers 3043. The second water-gas separation channel B is connected to the first water-gas separation channel A and is arranged parallel to it overall. The second water-gas separation channel B includes second separation chambers 3043 and a second baffle plate 3042, which is disposed opposite to the second separation chambers 3043 to change the liquid flow direction. The second baffle plate 3042 is arc-shaped, pointing towards the second separation chambers 3043 along the water-gas separation direction, and can generate a turbulent flow effect on the liquid entering the second water-gas separation channel B. The second water-gas separation channel B consists of multiple curved baffle sections (not shown in the attached figure).

[0068] As needed, such as Figure 5 , Figure 6 As shown, the pressure relief mechanism also includes a balance channel C penetrating the water-gas separation body 3030. Specifically, the water-gas separation body 3030 is provided with a first balance hole 3034 and a second balance hole 3033 connected to the balance channel C. The balance channel C is parallel to the first water-gas separation channel A and consists of multiple curved turbulence sections. Its structure is the same as the second water-gas separation channel B, but its direction is opposite to that of the second water-gas separation channel B.

[0069] As needed, such as Figure 5 , Figure 6 As shown, the separation inlet 3032 and the separation outlet 3031 are at the same end of the water-gas separation body 3030, which allows for better space to extend the length of the first water-gas separation channel A and / or the second water-gas separation channel B, thereby achieving a better separation effect.

[0070] As a possible implementation method, such as Figure 7 , Figure 8 As shown, the separation inlet 3032 and separation outlet 3031 are located at opposite ends of the water-gas separation body 3030. At this time, the balance channel C is actually the first segment of the entire water-gas separation path. The balance channel C is parallel to the first water-gas separation channel A. It merges with the first water-gas separation channel A at the first balance hole 3034 at the end of the balance channel C. It is composed of multiple curved turbulence sections. Its structure is the same as that of the second water-gas separation channel B, but its direction is opposite to that of the second water-gas separation channel B. This allows for better space to extend the length of the first water-gas separation channel A and / or the second water-gas separation channel B, thereby achieving a better separation effect.

[0071] like Figure 3 , Figure 4 As shown, the release component 301 includes a pipe 302 connected at one end to the water-air separation component 303, and the other end of the pipe 302 connected to the pressure relief component 3010. The pressure relief component 3010 is provided with a pressure relief chamber 3011, and the pressure relief chamber 3011 is provided with a pressure relief opening 203A. The pressure relief opening 203A is provided with two elastic plates 203, and the pressure relief opening 203A is provided between the elastic plates 203 to remain closed when no pressure is released.

[0072] As needed, the two elastic plates 203 are inclined, and the gap between the two elastic plates 203 gradually decreases from the outside to the inside, with the ends of the two elastic plates in contact. The opening 203A is elongated, so that the opening 203A is in a closed state when the pressure is not released.

[0073] Specifically, such as Figure 9 As shown, when the inlet / outlet mechanism 10 of the balanced pressure water tank 1 is tilted downwards, a portion of the water-air separation component 303 on the side away from the inlet / outlet mechanism 10 is above the liquid surface H. Regardless of whether the opening of the suction pipe 106 is always below the liquid surface H, the balanced pressure water tank 1 still has the ability to release pressure to the outside of the pressure relief water tank device and also has the ability to continuously output clean water. When the inlet of the suction pipe 106 is below the liquid surface H, the suction pipe 106 can naturally achieve the function of "discharging water". When the inlet of the suction pipe 106 is above the liquid surface H, the vent hole (not shown in the figure) of the inlet / outlet mechanism 10 is lower than the liquid surface H and is only a very small bypass branch of the water outlet channel. The bypass branch of the vent hole can achieve the function of "discharging water" under the pressure of the liquid surface H. At the same time, due to the pressure difference between the inside and outside of the balanced pressure tank 1, the balanced pressure tank 1 used in this manner has the ability to both supply water to the outside and release pressure to the outside.

[0074] Specifically, such as Figure 10 As shown, when the inlet / outlet mechanism 10 of the balanced pressure water tank 1 is tilted upwards, a portion of the water-air separation component 303 is located above the liquid surface H on the side closest to the inlet / outlet mechanism 10. At this time, the opening of the suction pipe 106 is lower than the liquid surface H. Under the combined action of water pressure and air pressure, the pressure passes through the water-air separation component 303 and acts directly on the release component 301 of the balanced pressure water tank 1 along the pressure relief pipe. The release component 301 can specifically be a one-way valve. Due to the one-way conduction function of the one-way valve, the one-way valve is compacted and closed under the combined action of water pressure and air pressure. The vent of the inlet / outlet mechanism 10 is higher than the liquid surface H and is only a very small bypass branch of the water outlet channel. The vent is connected to the outside atmosphere. A detour structure (not shown in the attached figure) is provided before the vent to block the water flow to the bypass branch of the vent. Simply put, the bypass branch of the vent, which is connected to the outside atmosphere, can achieve the effect of "breathable but not water-permeable". At this time, the bypass branch of the vent, which connects to the outside atmosphere, has the ability to release pressure to the outside of the water supply device. Simultaneously, due to the pressure difference between the inside and outside of the water tank, and because the suction pipe 106 always has an inlet and / or suction hole below the liquid level H, the clean water output component can continuously output clean water. The balanced pressure water tank 1, used in this configuration, has the ability to release pressure to the outside of the tank and to continuously output clean water. Of course, when the liquid level H is lower than the inlet of the suction pipe 106, the balanced pressure water tank 1 will naturally be unable to continuously output clean water, at which point the user is prompted to add clean water to the balanced pressure water tank 1 to continue using the cleaner.

[0075] Because the water-air separation component generates multiple eddies in the liquid through the first water-air separation channel in the separation direction, it affects the flow of the liquid in the separation direction, but does not affect the passage of gas. Thus, water and gas can be separated. The separated gas is discharged to the outside of the water tank body through the release component, effectively and slowly releasing the pressure generated inside the water tank during the vehicle washing process, so as to balance the pressure inside and outside the water tank.

[0076] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
