Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to a switching element and a water outlet device. Background Technology

[0002] As spray gun performance continues to expand, the switching methods for different water output effects are mostly categorized into pressing, pushing, and rotating. When using the pressing method for water output switching, the force required under high pressure is usually significant, making operation difficult and limiting functionality; it only offers a single function and requires repeated operation, reducing the customer experience. When using the pushing method, the switching resistance is usually high, and the rotation angle required by rotating the valve core is too large, requiring significant force from the user and not easily achieved with simple finger flicks. When using the rotating method, the rotation angle and force need to be controlled, which can easily damage the device. Therefore, how to achieve effortless switching between high and low pressure using fewer components, with a small operating range, simple operation, and effective cost reduction is a problem that those in the field need to solve. Utility Model Content

[0003] The purpose of this invention is to provide a switching element and a water outlet device that can achieve effortless switching between high and low pressure using fewer parts, with a small operating range, simple operation, and effective cost reduction.

[0016] Optionally, the sealing component further includes a guide plate and a rotating shaft. The guide plate is provided with a first guide slope and a second guide slope, and the first guide slope and the second guide slope are inclined at an angle. The rotating shaft is located in the middle of the guide plate, and the two sealing heads are located at both ends of the guide plate.

[0046] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0047] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0049] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0050] like Figures 1-16 As shown, this embodiment provides a switching element, including a driving member 10, a rotating rod 20, and a blocking member 30. The driving member 10 is sleeved on the rotating rod 20 and can drive the rotating rod 20 to rotate relative to the blocking member 30 about the axis of the rotating rod 30. The blocking member 30 is provided with two blocking heads 32, which correspond to two water channels respectively. When one of the two water channels is open, the other is closed. The rotating rod 20 is provided with an abutment block 23, which slides against the blocking member 30. When the driving member 10 is pushed and the rotating rod 20 is driven to rotate, the abutment block 23 slides between the two blocking heads 32 to push one of the blocking heads 32 toward the corresponding water channel to block it, and causes the other blocking head 32 to move away from the corresponding water channel to open it.

[0051] On the other hand, the water outlet device includes a switching element, a housing 100, an adapter 50, a water outlet 60, and a water inlet 70. One end of the adapter 50 is connected to the switching element, and the other end is connected to the water outlet 60. The water inlet 70 is connected to the other end of the switching element. The housing 100 is sleeved on the outside of the switching element, the adapter 50, the water outlet 60, and the water inlet 70. The water outlet 60 and the water inlet 70 are both screwed to the housing 100. The drive member 10 of the switching element extends out of the housing 100.

[0052] Specifically, in this embodiment, the driving component 10 facilitates easy operation by the user. Pushing the driving component 10 enables the synchronous rotation of the rotating rod 20. By sliding the rotating rod 20 between the two sealing heads 32 of the sealing component 30, the two water channels can be opened and closed, completing the water channel switching. This not only reduces the rotation angle and operational effort but also simplifies the structure, reduces operating effort, and lowers product costs. It is suitable for spray guns with different water output effects. Correspondingly, the water output device equipped with the switching element can achieve complete spraying of two water channels, enabling effortless switching of water channels through simple operation at high and low pressure.

[0053] The specific structure of the switching element in this embodiment will be described below.

[0054] like Figures 3-13 As shown, in this embodiment, the switching element includes a driving component 10, a rotating rod 20, a blocking component 30, and a waterway assembly 40. Specifically, the driving component 10 is sleeved on the rotating rod 20, the blocking component 30 is rotatably disposed in the waterway assembly 40, the rotating rod 20 is located in the waterway assembly 40 and extends out of the waterway assembly 40 before being connected to the driving component 10, and the other end of the rotating rod 20 is away from the driving component 10 and can slide against the blocking component 30. By pushing the driving component 10, the rotating rod 20 can be driven to rotate relative to the blocking component 30 about the axis of the rotating rod 20, thereby pushing the blocking component 30, so that the opening and closing of different waterway channels can be achieved under the action of the blocking component 30. For example, in this embodiment, the two ends of the blocking component 30 correspond to two waterway channels respectively, and under the push of the rotating rod 20, one waterway channel can be blocked while the other waterway channel is opened.

[0055] like Figure 3 and Figure 5As shown, in this embodiment, the driving component 10 includes a toggle part 11 and a connecting part 12. The toggle part 11 is provided with an operating inclined surface 111, and the connecting part 12 is provided with a connecting hole 121. Optionally, the toggle part 11 has two operating inclined surfaces 111 arranged at an angle, which facilitates the user to push the driving component 10 through the operating inclined surfaces 111. By pushing in two different directions, different water channels can be opened or closed, making operation simple. Specifically, one end of the connecting part 12 is connected to the bottom of the toggle part 11, and the other end is sleeved on the rotating rod 20. Optionally, in this embodiment, the connecting part 12 is provided with a through connecting hole 121, and the rotating rod 20 passes through the connecting hole 121. The driving component 10 and the rotating rod 20 cannot rotate relative to each other, so that when the driving component 10 is pushed, the rotating rod 20 can move synchronously. For example, the connecting hole 121 is set to a non-circular shape, and the part connecting the rotating rod 20 and the driving member 10 is adapted to its shape to ensure stable insertion between the two and to allow them to move only axially and not rotate circumferentially. In other embodiments, the shape of the two can also be set to quadrilateral, hexagonal or other special shapes, which is not limited here.

[0056] Combination Figures 4-10 As shown, in this embodiment, the rotating rod 20 includes a rod body 21, a base 22, and an abutment block 23. The rod body 21 has a positioning step 211, and the abutment block 23 has a first inclined surface 231 and a second inclined surface 232. A first sealing ring 201 is fitted onto the rod body 21. Specifically, the base 22 is cylindrical, and the rod body 21 is positioned above the base 22 along its axial direction. The abutment block 23 is located on the side of the base 22, and the rod body 21, base 22, and abutment block 23 together form an L-shaped structure. Optionally, the driving member 10 is fitted onto the rod body 21 and positioned above the positioning step 211. The shape of the connecting hole 121 on the driving member 10 matches the shape of the rod body 21 to ensure a stable connection. The positioning step 211 also limits the movement range of the driving member 10 on the rod body 21. For example, the first sealing ring 201 is sleeved on the rod 21 and located between the drive member 10 and the base 22.

[0057] Furthermore, the abutment block 23 is disposed on the side of the base 22, and the top of the abutment block 23 is provided with a first inclined surface 231 and a second inclined surface 232, which are inclined at an included angle, and the junction of the two surfaces slides against the sealing member 30. For example, when the driving member 10 is pushed and the rotating rod 20 is driven to rotate synchronously with it, the junction of the first inclined surface 231 and the second inclined surface 232 can slide between the two ends of the sealing member 30, so as to push one end of the sealing member 30 toward its corresponding water channel to block it, and cause the other end to move away from the corresponding water channel to open it, thereby realizing that one of the two water channels is blocked and the other is open, which facilitates switching of water channels and makes it convenient for users to adjust.

[0058] Combination Figures 3-9 and Figures 11-12 As shown, in this embodiment, the sealing component 30 includes a guide plate 31, a sealing head 32, and a rotating shaft 33. The guide plate 31 is provided with a first guide slope 311 and a second guide slope 312. The sealing head 32 includes a connecting block 321, a sealing block 322, and a first limiting groove 323. A second sealing ring 301 is fitted onto the sealing component 30. Optionally, in this embodiment, the first guide slope 311 and the second guide slope 312 on the guide plate 31 are inclined at an included angle, and their connection is smoothly connected by an arc surface. Specifically, the junction of the first slope 231 and the second slope 232 can slide on the first guide slope 311 and the second guide slope 312. Specifically, the included angle between the first guide slope 311 and the second guide slope 312 is greater than the included angle between the first slope 231 and the second slope 232 to ensure stable movement of the abutment block 23 on the guide plate 31. For example, the guide plate 31 is recessed on the side facing the abutment block 23, and the abutment block 23 is protruding on the side facing the guide plate 31.

[0059] Specifically, the two sealing heads 32 are located at both ends of the guide plate 31, and the rotating shaft 33 is located in the middle of the guide plate 31, that is, on the back side of the connection between the first guide inclined surface 311 and the second guide inclined surface 312. Thus, through the sliding of the junction of the first inclined surface 231 and the second inclined surface 232 on the guide plate 31, combined with the rotating shaft 33, one of the two sealing heads 32 can be slowly lifted up while the other slowly descends at the same time, and the two sealing heads 32 rotate at the same angle. Optionally, the two sealing heads 32 can block or open two water channels respectively, and the abutment block 23 can move either of the two sealing heads 32 toward the corresponding water channel to block it, while moving the other sealing head 32 away from the corresponding water channel to open it. Thus, the water channel switching can be completed by pushing the drive member 10 in different directions.

[0060] Specifically, in each sealing head 32, the connecting block 321 is connected to the guide plate 31 to ensure structural stability. Further, the sealing block 322 is connected to the connecting block 321 via a connecting post, and a first limiting groove 323 is formed between the connecting block 321 and the sealing block 322. The second sealing ring 301 is located in the first limiting groove 323 and is fitted onto the outside of the connecting post, thereby improving the sealing effect of the sealing head 32 when sealing the water passage. For example, the sealing block 322 is made of corrosion-resistant rubber material to ensure stable sealing while avoiding damage to the inner wall of the channel during repeated switching.

[0061] Combination Figures 3-4 , Figures 6-9 ,as well as Figure 13As shown, in this embodiment, the waterway assembly 40 is provided with a first inner cavity 401, a first channel 402, a second channel 403, a through hole 404, a sealing groove 405, a limiting block 406, a second limiting groove 407, and a third sealing ring 408. Optionally, in this embodiment, the sealing member 30 is rotatably disposed in the first inner cavity 401, the base 22 and the abutment block 23 of the rotating rod 20 are both disposed in the first inner cavity 401, and the rod body 21 passes through the through hole 404 and extends out of the outside of the waterway assembly 40 to connect to the driving member 10.

[0062] Specifically, the first channel 402, the second channel 403, and the through hole 404 are all connected to the first inner cavity 401, and the two sealing heads 32 are respectively arranged corresponding to the first channel 402 and the second channel 403. This allows for the isolation or connection between the first channel 402 and the first inner cavity 401, and between the second channel 403 and the first inner cavity 401, thereby achieving the opening and closing of the two water channels. Specifically, the rotating shaft 33 is rotatably disposed between the two limiting blocks 406 and located on one side of the through hole 404. Correspondingly, the first channel 402 and the second channel 403 are located on both sides of the through hole 404, and the rotating shaft 33 is located between the first channel 402 and the second channel 403, thus ensuring the corresponding arrangement of the two sealing heads 32 with the two channels.

[0063] Furthermore, one side of the sealing groove 405 is connected to the through hole 404, and the other side is connected to the first inner cavity 401. It is also positioned between the first channel 402 and the second channel 403. The inner diameter of the sealing groove 405 is larger than the inner diameter of the through hole 404. Therefore, after the first sealing ring 201 is fitted onto the rod body 21, it can be confined within the sealing groove 405. Specifically, in this embodiment, the first sealing ring 201 is an umbrella-shaped sealing ring, with its closed side abutting against the bottom of the sealing groove 405 and its open side facing the first inner cavity 401. This prevents the first inner cavity 401 from communicating with the through hole 404, thus avoiding leakage. Figure 7 and Figure 13 As shown, the top outer sides of the two channels in the water channel assembly 40 are provided with second limiting grooves 407 for placing third sealing rings 408 to seal and prevent leakage.

[0064] The specific structure of the water outlet device in this embodiment will be described below.

[0065] like Figures 1-16As shown, the water outlet device in this embodiment includes the aforementioned switching element, housing 100, adapter 50, water outlet component 60, and water inlet component 70. Specifically, one end of the adapter 50 is connected to the top of the water channel assembly 40 of the switching element, the other end of the adapter 50 is connected to the water outlet component 60, and the water inlet component 70 is connected to the bottom of the water channel assembly 40. Further, the housing 100 is sleeved on the outside of the switching element, adapter 50, water outlet component 60, and water inlet component 70, and both the water outlet component 60 and the water inlet component 70 are screwed to the housing 100, thereby ensuring the overall stability of the water outlet device installation. Exemplarily, the housing 100 is provided with a clearance hole 101, and the drive component 10 of the switching element extends out of the clearance hole 101 to facilitate direct operation of the drive component 10 by the user. Optionally, in this embodiment, the outer shell 100 is configured as an L-shaped cavity structure, with the water outlet 60 and the adapter 50 both located in its shorter cavity, and the switching element and the water inlet 70 located in its longer cavity, thereby changing the water outlet direction for user convenience.

[0066] Combination Figure 3 , Figures 6-9 and Figures 14-15 As shown, in this embodiment, the adapter 50 includes a bracket 51 and a body 52. ​​The bracket 51 is provided with a fixing block 511, and the body 52 is provided with a stepped groove 521, a third limiting groove 522, a third channel 501, a fourth channel 502, a second inner cavity 503, a first annular cavity 504 and an arc groove 505, and is fitted with a fourth sealing ring 506 and a fifth sealing ring 507.

[0067] Optionally, in this embodiment, one end of the bracket 51 is provided with a fixing block 511, and a fixing groove is provided on the inner wall of the corresponding outer casing 100. The fixing block 511 can be inserted into the fixing groove, thereby ensuring the stable placement of the adapter 50 in the outer casing 100. Further, the other end of the bracket 51 is connected to the body 52, the body 52 is inserted into the water outlet 60, and the water outlet 60 is screwed to the inner wall of the outer casing 100, thereby ensuring the stability of the entire device. Figure 14 As shown, in this embodiment, the third channel 501 in the body 52 is connected to the second inner cavity 503, and the fourth channel 502 is connected to the first annular cavity 504, with the first annular cavity 504 located outside the second inner cavity 503, thus realizing two pathways. Combined with... Figure 15 As shown, an arc-shaped groove 505 is also provided in the first annular cavity 504, and the two sides of the arc-shaped groove 505 are respectively connected to the fourth channel 502 and the first annular cavity 504, thereby expanding the communication space between the fourth channel 502 and the first annular cavity 504 and improving the water flow efficiency. Combined with... Figure 6 and Figure 7 As shown, in this embodiment, the third channel 501 is connected to the first channel 402, and the fourth channel 502 is connected to the second channel 403, thereby ensuring the connection between the two waterways.

[0068] like Figure 3 , Figure 6 , Figure 14 As shown, in this embodiment, a stepped groove 521 is provided at the outer end of the second inner cavity 503 to limit the installation of the fourth sealing ring 506 and seal the second inner cavity 503. Correspondingly, a third limiting groove 522 is provided at the outer end of the first annular cavity 504 to limit the installation of the fifth sealing ring 507 and seal the first annular cavity 504. Further, the third channel 501 and the fourth channel 502 extend along the first direction, and the second inner cavity 503 and the first annular cavity 504 both extend along the second direction, and the first direction and the second direction are perpendicular to each other, thereby changing the water outlet direction and effectively improving the space utilization rate inside the outer shell 100.

[0069] like Figure 1 and Figure 16 As shown, specifically, the water outlet component 60 is provided with a central hole 601, a shower head hole 602, a second annular cavity 603, a third annular cavity 604, and a weight-reducing groove 605. Optionally, the central hole 601 is located at the center of the water outlet component 60, and several shower head holes 602 are provided, which are evenly arranged around the central hole 601, thereby achieving two water output effects to meet the user's needs. Further, a second annular cavity 603 is provided between the central hole 601 and the shower head hole 602, and the third annular cavity 604 is located outside the second annular cavity 603 and communicates with the shower head hole 602.

[0070] Combination Figures 6-9 As shown, specifically, the stepped groove 521 is inserted into the second annular cavity 603 and confined to the stepped surface of the second annular cavity 603, while the fourth sealing ring 506 abuts against the side wall of the second annular cavity 603 to achieve the limiting installation of the adapter 50 in the water outlet 60, and at the same time, the second inner cavity 503 is connected to the central hole 601, that is, the first channel 402, the third channel 501, the second inner cavity 503 and the central hole 601 constitute a complete first water channel. Correspondingly, the third limiting groove 522 is inserted into the third annular cavity 604, and the fifth sealing ring 507 abuts against the side wall of the third annular cavity 604, and at the same time, the first annular cavity 504 is connected to the shower hole 602, that is, the second channel 403, the fourth channel 502, the first annular cavity 504 and the shower hole 602 constitute a complete second water channel, and the switching element can realize the rapid switching between the first water channel and the second water channel. For example, a weight-reducing groove 605 is provided on the water outlet 60, and the weight-reducing groove 605 is arranged circumferentially along the central hole 601 and is not connected to the inside of the water outlet 60 to avoid leakage, thereby reducing the weight of the equipment.

[0071] like Figure 3 and Figure 6As shown, in this embodiment, the water inlet component 70 is provided with a water inlet channel 701, a connecting port 702, and a sixth sealing ring 703. Optionally, one end of the water inlet channel 701 is used for water inlet, and the other end is connected to the first inner cavity 401 of the water channel assembly 40 in the switching element through the connecting port 702 to ensure a stable water supply to the two water channels. Further, two sixth sealing rings 703 are provided between the outer side of the water inlet component 70 and the inner wall of the water channel assembly 40 to seal the bottom of the first inner cavity 401 and prevent leakage. Specifically, the switching element can enable the water inlet channel 701 to be connected to either the first water channel or the second water channel.

[0072] Working process: Water supply is ensured through the water inlet channel 701. The drive component 10 drives the rotating rod 20 to rotate, causing the abutment block 23 to slide on the first guide slope 311 and the second guide slope 312. (Example) Figure 8 As shown, when the abutment block 23 moves toward the sealing head 32 of the second water passage, the sealing head 32 of the first water passage moves away from the first channel 402 to open the first water passage, and the sealing head 32 of the second water passage moves toward the second channel 403 to block the second water passage. At this time, water enters the first inner cavity 401 through the inlet channel 701, and passes through the first channel 402, the third channel 501, and the second inner cavity 503 in sequence, and is ejected from the central hole 601. Figure 9 As shown, when the abutment block 23 moves toward the sealing head 32 of the first water channel, the sealing head 32 of the second water channel moves away from the second channel 403 to open the second water channel, and the sealing head 32 of the first water channel moves toward the first channel 402 to block the first water channel. At this time, water enters the first inner cavity 401 through the water inlet channel 701, and passes through the second channel 403, the fourth channel 502, and the first annular cavity 504 in sequence, and is sprayed out from the shower hole 602.
