Description

Technical Field

[0001] This invention relates to the field of vehicle cleaning technology, and in particular to a car wash device with a water pressure balancing function. Background Technology

[0002] Vehicle washing usually requires continuous washing to achieve high cleaning efficiency. However, when using a scrubbing roller, the surface of which is typically made of sponge, the wastewater is collected after squeezing the roller, and the squeezed-out air is also collected, causing an increase in pressure within the liquid 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 car wash device with a water pressure balancing function. This car wash device can effectively and slowly release the pressure generated inside the water tank during the vehicle washing 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 car wash device with a water pressure balancing function. The car wash device with a water pressure balancing function includes a pressure balancing water tank. The pressure balancing water tank includes 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 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 inclined, and the gap between the two elastic sheets gradually decreases from the outside to the inside, and they come into contact at the ends of the two elastic sheets.

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

[0021] This invention relates to a car wash device with a water pressure balancing function, comprising a pressure balancing water tank. The pressure balancing water tank includes 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 the water-air separation component 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. The 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. 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 vehicle washing, thus balancing the pressure inside and outside the tank.

[0054] 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.

[0055] like Figures 1-15 As shown, the present invention provides an embodiment of a car wash device with a water pressure balancing function.

[0056] The car wash device with water pressure balancing function includes a pressure balancing water tank 1, which includes a water tank body 20 and a pressure release mechanism 30 disposed in the water tank body. The pressure release mechanism 30 includes a water-air separation component 303 and a release component 301 connected to the water-air separation component 303 and communicating 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 disposed in the water-air separation body 3030, as well as a first water-air separation channel A communicating 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.

[0057] Specifically, such as Figure 1 , Figure 2 As shown, the car wash device with balanced water pressure function includes a body 4, a water tank 1 that snaps onto the upper front side of the body, a cleaning head housing 3 that extends outward from the front of the body to snap onto the wiping roller 2, and a handle 8 connected to the end of the body. The cleaning mechanism (not shown in the figure) is installed inside the cleaning head housing 3. The pump 5 and part of the delivery pipeline (not shown in the figure) in the cleaning fluid delivery mechanism are installed inside the body. Part of the delivery pipeline in the cleaning fluid delivery mechanism and a section of the pipeline in the cleaning fluid delivery mechanism that passes through the wiping roller 2 are installed inside the cleaning head housing 3. The control circuit board 6, battery 7, and display panel (not shown in the figure) of the handheld car wash machine are installed inside the handle 8. The body, cleaning head housing, and handle are all equipped with power harnesses, signal harnesses, and connectors (not shown in the figure) that provide power or sensor signal transmission to the car wash device.

[0058] Specifically, such as Figure 1 , Figure 3 , Figure 14 , Figure 15 As shown, a handle locking mechanism 41 is provided on one end of the body 4 that is connected to the handle 8, which tightly engages with the handle 8. The mechanism includes a locking button mechanism 411 and a spring 412, one end of which abuts against the locking button mechanism 411 and the other end of which abuts against the body 4. The locking button mechanism 411 includes a button structure (not shown in the figure) that is restricted to vertical movement only on the upper surface of the body 4 and a barb portion (not shown in the figure) that extends from the button structure toward the handle. The spring 412 presses against the locking button mechanism 411 to make the barb portion tightly engage the handle 8. A water tank locking mechanism 42 is provided on the upper surface of the middle part of the body 4 that abuts against one end of the water tank 1. It includes a locking button 421 that is restricted to vertical movement only on the upper surface of the body 4, a locking tongue 422 that is restricted to horizontal unidirectional movement only, and a spring 423 that abuts against the locking tongue 422 at one end and against the body 4 at the other end. The locking tongue 422 can be retracted backward after the locking button 421 is pressed, which makes it convenient for the user to remove the water tank 1. After the water tank 1 is installed back into the body 4, when the locking button 421 is released, the locking tongue 422 extends under the action of the spring 423 and can tightly lock the water tank 1.

[0059] Specifically, such as Figure 3 As shown, the machine body 4 and the cleaning head housing 3 are also equipped with a water tank outlet pipe 53, a clean water pipe 54, and a sewage pipe 55. The cleaning head housing 3 is equipped with a clean water output channel component 56 and a sewage return channel component 57 at both ends. The pump 5 includes a pump outlet 51 and a pump return port 52. One end of the water tank outlet pipe 53 is connected to the clean water output interface (not shown in the figure) of the water tank 1, and the other end is connected to the pump return port 52. One end of the clean water pipe 54 is connected to the pump outlet 51, and the other end is connected to the input interface (not shown in the figure) of the clean water output channel component 56. One end of the sewage pipe 55 is connected to the output interface (not shown in the figure) of the sewage return channel component 57, and the other end is connected to the sewage input interface (not shown in the figure) of the water tank 1.

[0060] Specifically, the car wash device with water pressure balancing function 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.

[0061] like Figures 6-13 As shown, the water-air separation component 303 is used to separate liquid from air, wherein the liquid includes water, etc.

[0062] like Figure 8 , Figure 9As 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.

[0063] 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.

[0064] As a feasible implementation method, in order to better form multiple intersecting turbulent vortices in the first water-air separation channel A, each first turbulence plate is at a 30-degree angle to the water-air separation channel.

[0065] like Figure 8 , Figure 9 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.

[0066] like Figure 8 , Figure 9As 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).

[0067] As needed, such as Figure 8 , Figure 9 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.

[0068] As needed, such as Figure 8 , Figure 9 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.

[0069] As a possible implementation method, such as Figure 10 , Figure 11 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.

[0070] like Figure 6 , Figure 7As 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.

[0071] 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.

[0072] Specifically, such as Figure 12 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.

[0073] Specifically, such as Figure 13As 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.

[0074] 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.

[0075] 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.
