Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of air pump valves, and particularly to an air pump valve. Background Art
[0002] The main function of an ACV air pump valve is to control the flow rate and pressure of the air pump to ensure the normal operation and stable output of the air pump. The specific functions of an ACV air pump valve (Automatic Control Valve) include:
[0003] 1. Controlling the flow rate: The ACV valve controls the flow rate of the air pump by adjusting the opening degree of the valve, ensuring that the gas flow rate output by the air pump meets the requirements, and avoiding too large or too small flow rates, which may affect the normal operation of the system;
[0004] 2. Adjusting the pressure: The ACV valve can automatically adjust the opening degree of the valve according to the change of the system pressure, keeping the pressure in the system stable within the set range, preventing the pressure from being too high or too low, and protecting the system equipment from damage;
[0005] 3. Protecting the system: When the system pressure is too high or too low, the ACV valve can automatically adjust to prevent the system from overpressure or underpressure, protecting the air pump and other related equipment from damage;
[0006] 4. Improving the efficiency: By precisely controlling the flow rate and pressure, the ACV valve can help the air pump operate efficiently, reduce energy waste, and improve the overall efficiency of the system.
[0007] Traditional ACV air pump valves generally include a valve core housing, a valve core, and a valve core driving structure. The valve core is controlled to slide within the valve core housing through the valve core driving structure to change the gas path and control the flow rate and air pressure. However, under low-temperature conditions, when cold air enters the air pump valve and meets high-temperature components, water vapor is generated. When this water vapor encounters low temperature, it may condense into ice, resulting in ice formation in the air pump valve. The ice formation can affect the normal operation of the air pump valve and may even cause it to become stuck or unable to operate normally. Summary of the Invention
[0008] Aiming at the above-mentioned existing technical deficiencies, the purpose of the present invention is to provide an air pump valve, which has the advantage of cleaning the ice formation in the intake passage and the outlet passage to reduce the possibility of ice formation affecting gas transmission.
[0009] To solve the above technical problems, the present invention adopts the following technical solutions:

An air delivery nozzle that closes the opening at the bottom end of the valve core housing is tightly inserted into the bottom end of the inner cavity of the valve core housing. A fixed valve core that closes the opening at the top end of the valve core housing is tightly inserted into the top end. The top end of the fixed valve core passes through the valve core housing. The fixed valve core passing through the valve core housing passes through the valve body and closes the opening at the top end of the distribution cavity. A movable valve core located between the air delivery nozzle and the fixed valve core is slidably connected in the inner cavity of the valve core housing.

The control component 7 includes an iron core, a static iron core, a coil frame, and a coil fixed between the outer support frame 12 and the inner support frame 13. Inside the inner support frame 13, a valve core housing 3 is fixed. The bottom end of the valve core housing 3 passes through the valve body 1 and closes the opening at the bottom of the distribution cavity 2. At the bottom end inside the valve core housing 3, a gas delivery nozzle 4 that closes the opening at the bottom of the valve core housing 3 is inserted and connected tightly. At the top end, a fixed valve core 5 that closes the opening at the top of the valve core housing 3 is inserted and connected tightly. The top end of the fixed valve core 5 passes through the valve core housing 3.

When the control component 7 is in the de-energized state, the movable valve core 6 abuts against the gas delivery nozzle 4, the intake channel 401 is closed, and the air outlet hole 301, the air passing gap 302, the air outlet channel 501, and the exhaust channel 101 are connected and form a second air outlet path. The control component 7 is a conventional structure, so no more details will be given here.
[0035] Such as Figure 3 , a first rubber seal ring that is sleeved outside the valve core housing 3 and closes the gap between the inner support frame 13 and the valve core housing 3 is fixed to the inner wall of the inner support frame 13. A second rubber seal ring that fills the gap between the fixed valve core 5 and the valve core housing 3 is nested outside the fixed valve core 5.
[0036] Such as Figure 2 And Figure 3 And Figure 4 And Figure 5 And Figure 6, in order to reduce the possibility that the intake passage 401, the outlet passage 501 and the air outlet hole 301 freeze under low temperature conditions, which affects the operation of the device, a first movable groove 601 is provided at the bottom end of the movable valve core 6.

[0037] As Figure 6 and Figure 7 , the first cleaning assembly 8 includes a first upper mounting ring 801 provided at the top of the first movable groove 601. A first upper limiting ring 802 is fixed to the lower surface of the first upper mounting ring 801. A first lower mounting ring 803 is fixed to the bottom of the first movable groove 601. A first lower limiting ring 804 is fixed to the upper surface of the first lower mounting ring 803. A wavy first limiting groove 805 is formed by the gap between the first upper limiting ring 802 and the first lower limiting ring 804. Two relatively arranged first short shafts 806 are slidably connected in the first limiting groove 805. A first connecting column 807 is fixed to the part of the first short shaft 806 extending out of the first limiting groove 805. The first connecting column 807 is slidably connected to the first upper mounting ring 801, the first lower mounting ring 803, the first upper limiting ring 802 and the first lower limiting ring 804. The bottom end of the first connecting column 807 extends out of the first lower mounting ring 803. A first vertical rod 808 is fixed to the part of the bottom end of the first connecting column 807 extending out of the first lower mounting ring 803. The first vertical rod 808 extends into the intake passage 401 and is slidably connected to the intake passage 401. A first cross bar 809 is fixed to the bottom end of the first vertical rod 808 entering the intake passage 401. First scraping plates 810 are fixed to both ends of the first cross bar 809. The first scraping plates 810 are in contact with the inner cavity wall of the intake passage 401. A first matching assembly for cooperating with the first cross bar 809 to control the rotation of the first cross bar 809 is provided in the intake passage 401. The first matching assembly includes a first fixed rod 811 fixed to the inner cavity wall of the intake passage 401. A first convex rubber block 812 is fixed to the middle position of the first fixed rod 811.
[0038] As Figure 3 and Figure 6 and Figure 7 , the central axes of the first movable groove 601, the intake passage 401, the first upper mounting ring 801, the first lower mounting ring 803, the first upper limiting ring 802, the first lower limiting ring 804, the first connecting column 807, the first vertical rod 808 and the first cross bar 809 coincide.
[0039] As Figure 3 and Figure 6 and Figure 7, the second cleaning component 9 includes a second upper mounting ring 901 fixed to the top of the second movable slot 502. A second upper limiting ring 902 is fixed to the lower surface of the second upper mounting ring 901. A second lower mounting ring 903 is fixed to the bottom of the second movable slot 502. A second lower limiting ring is fixed to the upper surface of the second lower mounting ring 903. A wavy second limiting slot 904 is formed by the gap between the second upper limiting ring 902 and the second lower limiting ring. Two relatively arranged second short shafts are slidably connected in the second limiting slot 904. A second connecting column 905 is fixed to the part of the second short shaft extending out of the second limiting slot 904. The second connecting column 905 is slidably connected to the second upper mounting ring 901, the second lower mounting ring 903, the second upper limiting ring 902 and the second lower limiting ring. The bottom end of the second connecting column 905 extends out of the second lower mounting ring 903. A second vertical rod is fixed to the part of the bottom end of the second connecting column 905 extending out of the second lower mounting ring 903. The bottom end of the second vertical rod is fixed with a second cross bar 906. Second scraping plates are fixed to both ends of the second cross bar 906. The second scraping plates are in contact with the inner cavity wall of the air outlet channel 501. A flow through slot is formed through the second connecting column 905 beside the second vertical rod. The flow through slot communicates with the air outlet channel 501 without affecting the gas flow. A second matching component for controlling the rotation of the second cross bar 906 in cooperation with the second cross bar 906 is provided on the movable valve core 6. The second matching component includes an upper mounting slot 907 formed in the middle position of the upper surface of the movable valve core 6. An upper rubber block 908 is fixed in the upper mounting slot 907. The top of the upper rubber block 908 extends out of the upper mounting slot 907. A second convex rubber block 909 is fixed to the part of the upper rubber block 908 extending out of the upper mounting slot 907. The second convex rubber block 909 extends into the air outlet channel 501 and is slidably connected to the air outlet channel 501. The part of the second convex rubber block 909 entering the air outlet channel 501 abuts against the second cross bar 906.
[0040] Such as Figure 3 And Figure 6 And Figure 7 , the central axes of the air outlet channel 501, the second movable slot 502, the second upper mounting ring 901, the second upper limiting ring 902, the second lower mounting ring 903, the second lower limiting ring, the second connecting column 905, the second vertical rod, and the second cross bar 906 coincide. The second scraping plates are in contact with the inner cavity wall of the air outlet channel 501.
[0041] Such as Figure 1 And Figure 2 And 3 And Figure 6 And Figure 7, when the control component 7 is in a power-off state, elastic potential energy is provided by the spring 11, and the movable valve core 6 moves downward until it abuts against the top end of the air delivery nozzle 4. At this time, the air outlet hole 301, the air passing gap 302, the air outlet channel 501, and the exhaust channel 101 are connected and form a second air outlet path. An annular rubber gasket is fixed on the lower surface of the movable valve core 6 beside the first movable groove 601 to reduce the possibility of damaging the device by impact. When the movable valve core 6 moves downward until the first raised rubber block 812 contacts the first cross bar 809 and pushes the first cross bar 809 upward, the upward movement of the first cross bar 809 will drive the first vertical bar 808, the first connecting column 807, and the first short shaft 806, which are integrally structured with the first cross bar 809, to move. The first short shaft 806 moves along the first limiting groove 805, which will drive the first cross bar and the first scraping plate 810 to rotate. When the bottom end of the movable valve core 6 abuts against the air delivery nozzle 4 and closes the air inlet channel 401, the first raised rubber block 812 pushes the first short shaft 806 to move upward to the highest point position in the first limiting groove 805.
[0042] As Figure 1 and Figure 2 and 3 and Figure 6 and Figure 7 , at the same time, the downward movement of the movable valve core 6 will cause the second cross bar 906 not to contact the second raised rubber block 909. At this time, the second short shaft rotates while moving downward along the second limiting groove 904 under the action of gravity, thereby driving the second scraping plate to rotate and scrape the ice and dirt on the inner cavity wall of the air outlet channel 501.
[0043] As Figure 1 and Figure 2 and 3 and Figure 6 and Figure 7 , a flow-through groove is penetrated through the second connecting column 905 beside the second vertical bar, and the flow-through groove is connected to the air outlet channel 501, which does not affect the gas flow. The air outlet hole 301, the air passing gap 302, the air outlet channel 501, the flow-through groove, and the exhaust channel 101 are connected and form a second air outlet path.
[0044] As Figure 1 and Figure 2 and 3 and Figure 6 and Figure 7When the control component 7 is powered on, the movable valve core 6 moves upward until it abuts against the bottom of the fixed valve core and closes the air outlet passage 501. During the upward movement, the second connecting column 905 contacts the second cross bar 906 and pushes the second cross bar 906 upward. The upward movement of the second cross bar 906 drives the second short shaft and the second connecting column 905, which are of an integrated structure with the second cross bar 906, to move upward. The second short shaft moves upward along the second limiting groove 904. When the movable valve core 6 moves to abut against the bottom of the fixed valve core and closes the air outlet passage 501, the second short shaft moves upward to the highest point along the second limiting groove 904. At this time, the air outlet passage 501 communicates with the air outlet hole 3.
[0045] Such as Figure 1 and Figure 2 and 3 and Figure 6 and Figure 7 Meanwhile, the upward movement of the movable valve core 6 causes the first cross bar 809 not to contact the first convex rubber block 812. At this time, the first short shaft 806 moves downward and rotates along the first limiting groove 805 under the action of gravity, thereby driving the first scraping plate 810 to rotate and scrape the ice and dirt on the inner cavity wall of the air inlet passage 401.
[0046] Such as Figure 1 and Figure 2 and 3 and Figure 6 and Figure 7 Repeat the above operations to facilitate the cleaning of the ice and dirt in the air inlet passage 401 and the air outlet passage 501.
[0047] Such as Figure 3 and Figure 4 and Figure 5 The third cleaning component 10 includes an annular bottom plate 1003 fixed to the bottom of the inner cavity groove of the valve core housing 3. An annular turntable 1001 is arranged directly above the annular bottom plate 1003. Both the annular bottom plate 1003 and the annular turntable 1001 are nested outside the air delivery nozzle 4. The annular bottom plate 1003 is fixedly connected to the air delivery nozzle 4, and the annular turntable 1001 is rotatably connected to the air delivery nozzle 4. Two relatively arranged first sliding grooves are formed on the upper surface of the annular bottom plate 1003. First sliders are slidably connected in the first sliding grooves. The top ends of the first sliders extend out of the first sliding grooves, and the first sliders extending out of the first sliding grooves are fixed to the lower surface of the annular turntable 1001. By providing the first sliding grooves and the first sliders, it is convenient for the annular turntable 1001 to rotate around the center line of the annular bottom plate 1003. Two relatively arranged cleaning rods 1002 are fixed to the circumferential outer wall of the annular turntable 1001 and are located beside the air outlet hole 301. The cross section of the cleaning rod 1002 is L-shaped and contacts the inner cavity wall of the valve core housing 3. When the annular turntable 1001 and the cleaning rods 1002 rotate, the ice on the air outlet hole 301 is scraped off, and at the same time, the ice in the air outlet hole 301 is vibrated and falls off.
[0048] Such asFigure 3 and Figure 4 and Figure 5 On the upper surface of the annular bottom plate 1003, there are also two second chutes 1004 which are arranged oppositely and are beside the first chute. A second slider 1005 with an L-shaped cross-section is slidably connected to the second chute 1004. On one side of the upper surface of the second slider 1005, a third slider 1006 is fixed. Two oppositely arranged third chutes 1007 penetrate through the annular turntable 1001. The third slider 1006 extends into the third chute 1007 and is slidably connected to the third chute 1007. By providing the second chute 1004 and the second slider 1005, it is convenient for the second slider 1005 to move in the direction of the second chute 1004. The movement of the second slider 1005 will drive the third slider 1006 fixed to the second slider 1005 to slide in the third chute 1007, thereby driving the annular turntable 1001 to rotate. On the other side of the upper surface of the second slider 1005, a lower wedge block 1008 is fixed. On the circumferential outer wall of the movable valve core 6, two oppositely arranged connecting rods 1009 are fixed. On the lower surface of the connecting rod 1009, an upper wedge block 1010 which cooperates with the lower wedge block 1008 is fixed. The upper wedge block 1010 is slidably connected to the inner cavity wall of the valve core housing 3. The inner cavity wall of the valve core housing 3 and the outer wall of the second slider 1005 are connected by an elastic sheet.
[0049] such as Figure 3 and Figure 4 and Figure 5 When the control component 7 is in a power-off state, the elastic potential energy is provided by the spring 11, and the movable valve core 6 moves downward. The downward movement of the movable valve core 6 will drive the connecting rod 1009 and the upper wedge block 1010 which are of an integrated structure with the movable valve core 6 to move downward. When the upper wedge block 1010 contacts the lower wedge block 1008, it will push the second slider 1005 and the third slider 1006 which are of an integrated structure with the lower wedge block 1008 to move, and the elastic sheet is stretched, thereby driving the annular turntable 1001 to rotate. The rotation of the annular turntable 1001 will drive the cleaning rod 1002 to rotate, scraping the ice on the air outlet 301 and causing the ice in the air outlet 301 to fall off due to vibration.
