Description

Technical Field

[0001] This invention relates to the technical field of bathroom accessories, and in particular to a pressurized valve core housing assembly. Background Technology

[0002] Common faucet valve cores on the market usually only have the function of discharging water. During peak water usage periods in the morning, noon and evening, users use water in a concentrated manner, resulting in low water pressure. This causes the water flow of faucets in high-rise buildings to be very small, which brings inconvenience to users' normal water use. Moreover, when multiple places in the house use water at the same time, the water flow of the faucet will also decrease. However, most existing valve core housing components adopt the bottom water inlet and top water outlet method, which makes it difficult to achieve the pressure boosting effect.

[0003] In view of this, the inventors specifically designed a pressurizable valve core housing assembly, which led to this invention. Summary of the Invention

[0004] To solve the above problems, the technical solution of the present invention is as follows:

[0005] A pressure-boosting valve core housing assembly includes an upper housing and a lower housing. The lower housing is disposed below the upper housing. At least one water inlet channel is provided above the upper housing, connecting the outer side wall and the inner side wall of the upper housing. A water outlet channel is provided below the lower housing. The cross-sectional area of ​​the water outlet channel is smaller than that of the water inlet channel.

[0006] Furthermore, the water inlet channel is provided in two ways, including a first channel and a second channel, and the water flow from the first channel and the second channel can flow into the water outlet channel.

[0007] Furthermore, the first channel and the second channel have the same cross-sectional area, and both are larger than the cross-sectional area of ​​the water outlet channel.

[0008] Furthermore, at least two buckles are provided on the lower part of the upper housing, and buckles that engage with the slots are provided on the lower housing.

[0009] Furthermore, at least two positioning platforms are provided on the lower end face of the upper housing, and positioning grooves that cooperate with the positioning platforms are provided on the lower housing.

[0010] Furthermore, a sealing step is also provided on the lower housing to serve a sealing function.

[0011] Furthermore, the length of the water outlet channel is 3-8cm.

[0012] The valve core housing assembly of the present invention can achieve water inlet at the top and water outlet at the bottom by setting a water inlet channel in the upper housing and a water outlet channel in the lower housing. At the same time, the cross-sectional area of ​​the water outlet channel is smaller than that of the water inlet channel, which can achieve a pressurization effect. Attached Figure Description

[0027] To make the technical problems, solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention.

[0028] Please see Figures 1 to 3This is a pressurized valve core housing assembly, which is the preferred embodiment of the present invention. It includes an upper housing 10 and a lower housing 20. The lower housing 20 is disposed below the upper housing 10. At least one water inlet channel is provided above the upper housing 10, connecting the outer side wall and the inner side wall of the upper housing 10. A water outlet channel 21 is provided below the lower housing 20. The cross-sectional area of ​​the water outlet channel 21 is smaller than the cross-sectional area of ​​the water inlet channel. The length of the water outlet channel 21 is 3-8 cm.

[0029] The present invention provides two water inlet channels, including a first channel 11 and a second channel 12 respectively. The water flow from the first channel 11 and the second channel 12 can flow into the water outlet channel 21. The first channel 11 is a cold water channel and the second channel 12 is a hot water channel. The cross-sectional areas of the first channel 11 and the second channel 12 are the same and are both larger than the cross-sectional area of ​​the water outlet channel 21.

[0030] To facilitate the assembly of the upper housing 10 and the lower housing 20, at least two snap fasteners 23 are provided on the lower part of the upper housing 10, and snap fasteners 23 that engage with the slots 14 are provided on the lower housing 20. Preferably, at least two positioning platforms 22 are provided on the lower end face of the upper housing 10, and positioning grooves 13 that engage with the positioning platforms 22 are provided on the lower housing 20. Furthermore, to achieve a good sealing effect, a sealing step 24 that serves a sealing function is also provided on the lower housing 20.

[0031] Please see Figures 4-10 The valve core housing assembly of the present invention is applied to the entire valve core assembly, as follows:

[0032] A sealing structure, a fixed sealing plate, a dynamic sealing plate, and a sealing block are sequentially arranged between the upper housing 10 and the lower housing 20. The dynamic sealing plate is adjusted by an adjustment assembly, which includes a limiting rotating sleeve, a rotating shaft, and an adjustment rod. Both the fixed and dynamic sealing plates are made of ceramic. The limiting rotating sleeve, the fixed sealing plate, and the dynamic sealing plate are confined inside the upper housing 10 by the lower housing 20. The limiting rotating sleeve is rotatably connected to the upper housing 10. The upper part of the adjustment rod is used to connect to the handle, the middle part is rotatably connected to the limiting rotating sleeve, and the lower part passes through the fixed sealing plate and connects to the dynamic sealing plate. When the adjustment rod is rotated, it drives the limiting rotating sleeve and the dynamic sealing plate to rotate, thereby adjusting the proportion of water flowing into the water outlet channel 21 from the first channel 11 and the second channel 12. Pushing the adjustment rod drives the dynamic sealing plate to move, thereby opening or closing the water flowing into the water outlet channel 21 from the first channel 11 and the second channel 12. Meanwhile, the fixed sealing sheet, the dynamic sealing sheet, and the sealing block are all provided with a first water passage for connecting the first channel 11 and the water outlet channel 21, and a second water passage for connecting the second channel 12 and the water outlet channel 21; in order to limit the rotation angle of the limiting rotating sleeve inside the upper housing 10, a rotation limiting groove is provided inside the upper housing 10, and a rotation limiting boss that cooperates with the rotation limiting groove is provided on the outer wall of the limiting rotating sleeve; a first boss for limiting the rotation angle of the limiting rotating sleeve is provided inside the rotation limiting groove, and a first groove that cooperates with the first boss is provided on the rotation limiting boss.

[0033] The middle part of the adjusting rod is rotatably connected to the limiting rotating sleeve through the first groove of the rotating shaft. Using the lever principle, when the upper end of the adjusting rod is pushed, its lower end drives the dynamic sealing plate to move. Specifically, the outer side of the limiting rotating sleeve is a circular surface, and its interior is a square through hole. The adjusting rod is provided with a square part that fits into the square through hole. When the adjusting rod is rotated, the rotation angle of the adjusting rod is limited by the limiting rotating sleeve. At the same time, a clearance position is provided inside the square through hole to avoid the adjusting rod when it is pushed. The middle part of the fixed sealing plate is provided with a clearance hole first groove to avoid the adjusting rod. The lower end of the adjusting rod is square in shape, and the upper end surface of the dynamic sealing plate is provided with a square groove that fits into the bottom of the adjusting rod.

[0034] A first groove for sealing structure is provided between the upper end face of the fixed sealing sheet and the upper housing 10 to prevent water leakage between the first channel 11 and the second channel 12. Specifically, the first groove includes a first sealing ring and a second sealing ring arranged concentrically. At least one connecting strip is provided between the first and second sealing rings; preferably, the present invention provides two connecting strips to facilitate the installation of the entire first groove of the sealing structure. A first annular groove and a second annular groove are provided on the side of the upper housing 10 that contacts the upper end face of the fixed sealing sheet to accommodate the first and second sealing rings. A connecting groove for accommodating the connecting strip is provided between the first and second annular grooves. At least one second boss is provided on the side of the upper housing 10 that contacts the upper end face of the fixed sealing sheet to prevent rotation of the fixed sealing sheet. A second groove that mates with the second boss is provided on the fixed sealing sheet; preferably, the present invention provides two second bosses and two second grooves to better constrain the fixed sealing sheet.

[0035] The lower housing 20 is provided with at least one third boss for restricting the rotation of the sealing block, and the sealing block is provided with a third groove that engages with the third boss. Preferably, the present invention provides four third bosses and four third grooves.

[0036] The upper housing 10 is also provided with a third annular groove for placing the third sealing ring and a fourth annular groove for placing the fourth sealing ring. The third annular groove is located above the first water passage, and the fourth annular groove is located between the first water passage and the second water passage. These sealing methods are conventional technical means and will not be described in detail here.

[0037] In this invention, cold water is introduced into the first channel 11 and hot water into the second channel 12. The ratio of cold water to hot water flowing into the outlet channel 21 is adjusted using a dynamic sealing plate. When the first channel 11 is connected to the outlet channel 21, the central axis of the outlet channel 21 is close to the center of the outlet of the first channel 11 (preferably concentric), and the opening of the outlet of the first channel 11 gradually decreases. That is, the opening of the first water passage (cold water passage) located on the dynamic sealing plate gradually decreases, which can achieve the effect of pressurizing cold water. At the same time, the center of the outlet of the first channel 11 is close to the center of the outlet channel 21. Since the outlet channel 21 has a certain length, the hot water can be driven during the pressurization of cold water using the principle of fluid mechanics, thereby achieving pressurization of the mixed water.

[0038] In summary, the valve core housing assembly of the present invention, by providing a water inlet channel in the upper housing and a water outlet channel in the lower housing, can achieve water inlet at the top and water outlet at the bottom. At the same time, the cross-sectional area of ​​the water outlet channel is smaller than that of the water inlet channel, thus achieving a pressurization effect.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
