Description

Technical Field

[0001] This application relates to the field of water purifier technology, specifically to a micro-pressure water outlet box. Background Technology

[0002] Integrated water purifiers and water heaters provide both room temperature and hot water, making them increasingly popular and gradually becoming an indispensable household appliance. These purifiers typically consist of a filter cartridge, an instant heating element, and a water outlet box. Their working principle involves the filter cartridge directly outputting purified water from the tap water source, or the instant heating element heating the water before outputting it. This allows for the dispensing of either room temperature or hot water when connected to the water outlet box. Furthermore, after inputting a hot water dispensing command, the instant heating element activates, dispensing hot water from the water outlet box within 3-5 seconds, meeting users' needs for quick access to hot water.

[0003] However, in areas with high altitude and low air pressure, the boiling point of water will be lower. When using a water purifier with integrated heating and cooling in these areas, the highest temperature that the instant heating element can heat water to is generally 95℃, and the water is not truly boiled. In addition, because there is a water outlet pipe between the instant heating element and the water outlet box, the hot water output by the instant heating element will lose some heat when flowing in the water outlet pipe, which will cause the hot water temperature to drop. As a result, the boiling water temperature received by users is often lower than 90℃, which cannot meet the user's need for hot water. Utility Model Content

[0004] This application provides a low-pressure water outlet box to solve the technical problems of the instantaneous heating element of the integrated water purifier and water heater used in areas with high altitude and low air pressure having difficulty boiling water and the highest temperature of the discharged water usually being below 90°C.

[0005] The technical solution adopted in this application is as follows:

[0006] A low-pressure water outlet box includes a box body and a box cover, the box cover and the box body forming a hot water outlet cavity. The box body has a hot water inlet and a hot water outlet respectively communicating with the hot water outlet cavity. The low-pressure water outlet box also includes a pressure-boosting water-blocking component and a reset driving component. The pressure-boosting water-blocking component is rotatably disposed in the hot water outlet cavity. The pressure-boosting water-blocking component can be rotated in the pressure-boosting direction that closes the hot water inlet under the driving action of the reset driving component, so as to create resistance to the water flow in the hot water inlet entering the hot water outlet cavity.

[0007] In this technical solution, a flip-up pressure-boosting baffle is provided in the hot water outlet chamber. When no hot water enters the hot water inlet, the pressure-boosting baffle closes the hot water inlet under the driving action of the reset drive. When hot water enters the hot water inlet, the pressure-boosting baffle overcomes the driving force applied by the reset drive under the pushing action of the water flow and flips to open the hot water inlet, allowing hot water to enter the hot water outlet chamber. In other words, the driving force applied by the reset drive on the pressure-boosting baffle acts in the opposite direction on the water flow, forming resistance to the water flow entering the hot water inlet and limiting the flow, thereby pressurizing the upstream water path of the hot water inlet and generating a micro-pressure effect. Therefore, the micro-pressure water outlet box can be applied to integrated water purifiers, and connected to the instant heating element of the integrated water purifier through the hot water inlet. Utilizing the resistance generated by the water flow from the instant heating element to the hot water inlet by the pressure-boosting baffle, the heating chamber of the instant heating element is pressurized, generating micro-pressure within the instant heating element. This increases the pressure within the instant heating element, making it higher than atmospheric pressure. Consequently, the boiling point of the water within the instant heating element is also higher than the boiling point under atmospheric pressure. The boiling point of water also increases with increasing pressure. Therefore, the instant heating element can heat water to a temperature of at least 100℃ to truly boil the water. Moreover, even if some heat is lost during the flow of boiling water to the micro-pressure water outlet box, the water temperature can still be maintained above 95℃ upon reaching the box, meeting the needs of users in high-altitude, low-pressure areas to obtain hot water of at least 95℃ from the integrated water purifier.

[0008] The reset drive is a permanent magnet, and the pressure boosting and water blocking component is a magnetic structure. The reset drive drives the pressure boosting and water blocking component to flip along the pressure boosting direction through magnetic attraction.

[0009] In this technical solution, the principle of magnetic attraction of a permanent magnet to a magnetic structure is used to drive the pressure-boosting baffle to flip along the pressure-boosting direction of the closed hot water inlet. The magnetic attraction of the permanent magnet to the magnetic structure is related to the distance between them. When high-temperature hot water is discharged at a small flow rate, the flip angle of the pressure-boosting baffle opening the hot water inlet is small, and the position is close to the permanent magnet, resulting in greater resistance to the water flow entering the hot water inlet. This, in turn, strengthens the pressure boosting capacity of the water path connected to the upstream of the hot water inlet, which helps to raise the water temperature. When low-temperature hot water is discharged at a large flow rate, the flip angle of the pressure-boosting baffle opening the hot water inlet is large, and the position is far from the permanent magnet, resulting in less resistance to the water flow entering the hot water inlet. This reduces the flow restriction effect on the water flow and, while having a certain pressure boosting effect, can meet the demand for large flow rates.

[0010] The box body is provided with an outwardly protruding water inlet guide pipe, the hot water inlet is formed inside the water inlet guide pipe, and the reset drive is located on the outside of the box body and sleeved on the water inlet guide pipe.

[0011] In this technical solution, by placing the reset drive component on the outside of the housing, the reset drive component exerts a magnetic attraction on the pressure-boosting baffle located inside the housing, causing it to flip and close the hot water inlet. Furthermore, the reset drive component does not occupy the internal space of the hot water outlet chamber and does not come into contact with the hot water, thus not affecting the water quality. The reset drive component is sleeved on the inlet guide pipe and arranged around the hot water inlet. The magnetic attraction generated by the reset drive component on the pressure-boosting baffle also surrounds the hot water inlet, enabling more effective and stable magnetic attraction of the pressure-boosting baffle, causing it to flip in the direction of closing the hot water inlet, thereby improving the pressure boosting effect.

[0012] The reset drive includes a first arc segment and a second arc segment that are magnetically attracted together. The box body is provided with a limiting groove, and the box cover is provided with a stop portion. The stop portion stops and confines the reset drive within the limiting groove.

[0013] In this technical solution, by setting the reset drive component as a separate first arc segment and second arc segment, the first arc segment and the second arc segment can be magnetically connected after approaching each other from both sides of the water inlet guide pipe, thereby realizing the installation of the water inlet guide pipe and improving the ease of installation of the reset drive component; after the reset drive component is installed, the stop part stops and limits the reset drive component to prevent it from falling out of the limit groove.

[0014] The pressurizing and water-blocking component is provided with a rotating shaft, and the box body is provided with a hook portion adapted to the rotating shaft portion, and the rotating shaft portion is rotatably hung in the hook portion.

[0015] This technical solution provides an embodiment of a pressure-boosting water-blocking component that uses a rotating shaft and a hook for rotatable engagement. The structure is simple and easy to install.

[0016] The box cover is provided with an anti-slip rib, which stops and confines the rotating shaft within the hook portion.

[0017] In this technical solution, the rotating shaft is stopped and confined within the hook by the anti-detachment baffle, thus limiting the rotating shaft to its rotational freedom, improving the reliability of the pressurizing baffle and preventing the rotating shaft from detaching from the hook.

[0018] The box cover is provided with a corner limiting protrusion, and the inner wall of the box body and the corner limiting protrusion limit the rotation angle range of the pressurizing water baffle.

[0019] In this technical solution, a corner-limiting protrusion is provided on the cover to limit the opening and closing angle of the pressure-boosting water-blocking component. The pressure-boosting water-blocking component reaches its maximum opening angle when it flips along the direction of opening the hot water inlet to abut against the corner-limiting protrusion. The corner-limiting protrusion prevents the pressure-boosting water-blocking component from opening and closing too large an angle when impacted by high-velocity water. It also confines the pressure-boosting water-blocking component within the range where the reset drive can magnetically flip and reset it, preventing the pressure-boosting water-blocking component from being too far from the reset drive, which would prevent the reset drive from magnetically flipping and resetting the pressure-boosting water-blocking component towards the direction of closing the hot water inlet after hot water flow stops.

[0020] The pressurizing water-blocking component is equipped with a flipping arm, and the box cover is formed by two symmetrically arranged buckles forming a slot, into which the flipping arm can be rotatably inserted.

[0021] In this technical solution, the pressure-boosting water-blocking component is rotatably engaged with the slot by a flipping arm, thereby providing an embodiment in which the pressure-boosting water-blocking component is rotatably connected to the box cover. The structure is simple and the installation is convenient.

[0022] The reset drive is a torsion spring, and the pressure-boosting water-blocking component is rotatably connected to the box cover via a rotating part. The torsion spring includes a fixed end and an elastic end. The fixed end abuts against the box cover, and the elastic end abuts against the pressure-boosting water-blocking component.

[0023] In this technical solution, the torsion spring is set between the pressure-boosting baffle and the cover. When the water flow from the hot water inlet acts on the pressure-boosting baffle, it causes the baffle to flip and open the hot water inlet and compress the torsion spring. The elastic force generated by the compression of the torsion spring reacts to the water flow through the pressure-boosting baffle, increasing the water flow resistance.

[0024] The reset drive is a torsion spring, and the pressure-boosting water-blocking component is rotatably connected to the box body via a rotating part. The torsion spring includes a fixed end and an elastic end. The fixed end abuts against the box body, and the elastic end abuts against the pressure-boosting water-blocking component.

[0025] In this technical solution, the torsion spring is set between the pressure-boosting baffle and the box body. When the water flow from the hot water inlet acts on the pressure-boosting baffle, it causes the pressure-boosting baffle to flip and open the hot water inlet and compress the torsion spring. The elastic force generated by the compression of the torsion spring reacts to the water flow through the pressure-boosting baffle, increasing the water flow resistance.

[0026] The box body is provided with an exhaust section higher than the hot water outlet, and the exhaust section forms an exhaust channel; the box cover and the box body form a cold water outlet cavity, the box body is provided with a partition separating the hot water outlet cavity and the cold water outlet cavity, and the box body is provided with a cold water inlet and a cold water outlet respectively connected to the cold water outlet cavity.

[0027] In this technical solution, the exhaust section is higher than the hot water outlet, and an exhaust channel is provided inside the exhaust section, making the hot water outlet chamber a water-vapor separation chamber. Hot water and steam are separated in the hot water outlet chamber. The steam flows upward and enters the exhaust channel, while the hot water flows downward and is discharged through the hot water outlet, avoiding excessive mixing of steam in the hot water and thus reducing the impact of steam on the hot water outlet pattern. In addition, a partition separates the hot water outlet chamber from the cold water outlet chamber, allowing hot and cold water to be discharged separately in the micro-pressure water outlet box, avoiding mixing of hot and cold water and ensuring the accuracy of the hot water outlet temperature.

[0028] Due to the adoption of the above technical solution, the technical effect achieved by this application is as follows: a flip-up pressure-boosting baffle is provided in the hot water outlet chamber. When no hot water enters the hot water inlet, the pressure-boosting baffle closes the hot water inlet under the driving action of the reset drive. When hot water enters the hot water inlet, the pressure-boosting baffle overcomes the driving force applied by the reset drive under the pushing action of the water flow and flips to open the hot water inlet, allowing hot water to enter the hot water outlet chamber. In other words, the driving force applied by the reset drive on the pressure-boosting baffle acts in the opposite direction on the water flow, forming resistance to the water flow entering the hot water inlet and limiting the flow, thereby pressurizing the upstream water path of the hot water inlet and generating a micro-pressure effect. Therefore, the micro-pressure water outlet box can be applied to integrated water purifiers, and connected to the instant heating element of the integrated water purifier through the hot water inlet. Utilizing the resistance generated by the water flow from the instant heating element to the hot water inlet by the pressure-boosting baffle, the heating chamber of the instant heating element is pressurized, generating micro-pressure within the instant heating element. This increases the pressure within the instant heating element, making it higher than atmospheric pressure. Consequently, the boiling point of the water within the instant heating element is also higher than the boiling point under atmospheric pressure. The boiling point of water also increases with increasing pressure. Therefore, the instant heating element can heat water to a temperature of at least 100℃ to truly boil the water. Moreover, even if some heat is lost during the flow of boiling water to the micro-pressure water outlet box, the water temperature can still be maintained above 95℃ upon reaching the box, meeting the needs of users in high-altitude, low-pressure areas to obtain hot water of at least 95℃ from the integrated water purifier.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0058] In the embodiments of this application, a micro-pressure water outlet box is provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0059] refer to Figures 1 to 16 As shown, the micro-pressure water outlet box provided in this application includes a box body 1 and a box cover 2. The box cover 2 and the box body 1 form a hot water outlet cavity 3. The box body 1 is provided with a hot water inlet 11 and a hot water outlet 12 that are respectively connected to the hot water outlet cavity 3. The micro-pressure water outlet box also includes a pressure-boosting water-blocking component 4 and a reset driving component. The pressure-boosting water-blocking component 4 is rotatably disposed in the hot water outlet cavity 3. The pressure-boosting water-blocking component 4 can be rotated in the pressure-boosting direction that closes the hot water inlet 11 under the driving action of the reset driving component, so as to form resistance to the water flow in the hot water inlet 11 entering the hot water outlet cavity 3.

[0060] Specifically, such as Figure 2 The image shows the state of the pressure booster baffle 4 when it is located in the closed hot water inlet 11, as shown. Figure 3The diagram shows the state of the pressure-boosting baffle 4 when the hot water inlet 11 is opened under the action of water flow, with the arrow indicating the direction of water flow. In this technical solution, when no hot water enters the hot water inlet 11, the pressure-boosting baffle 4 closes the hot water inlet 11 under the driving action of the reset drive; when hot water enters the hot water inlet 11, under the pushing action of the water flow, the pressure-boosting baffle 4 overcomes the driving force applied by the reset drive and flips to open the hot water inlet 11, allowing hot water to enter the hot water outlet chamber 3. In other words, the driving force applied by the reset drive on the pressure-boosting baffle 4 acts in the opposite direction to the water flow, forming resistance to the water flow entering the hot water inlet 11 and limiting the flow, thereby pressurizing the upstream water path of the hot water inlet 11 and generating a micro-pressure effect.

[0061] Therefore, the micro-pressure water outlet box can be applied to an integrated water purifier and heating system. The micro-pressure water outlet box is connected to the instantaneous heating element of the integrated water purifier and heating system through the hot water inlet 11. The resistance generated by the water flow from the instantaneous heating element to the hot water inlet 11, located in the pressure-boosting baffle 4, is used to pressurize the heating chamber of the instantaneous heating element, generating micro-pressure within the instantaneous heating element. This increases the pressure within the instantaneous heating element, making the pressure higher than normal pressure. Consequently, the boiling point of the water flow within the instantaneous heating element is also higher than the boiling point under normal pressure. The boiling point of water also increases with the increase of pressure. Therefore, when heating water, the instantaneous heating element can heat the water to a temperature of not less than 100℃ to truly boil the water. Moreover, even if some heat is lost during the process of boiling water flowing to the micro-pressure water outlet box, the water temperature can still be ensured to be above 95℃ when it reaches the micro-pressure water outlet box. This meets the needs of users in high-altitude and low-pressure areas to obtain high-temperature boiling water of not less than 95℃ from the integrated water purifier and heating system. In addition, since the pressure-boosting water baffle 4 is located in the low-pressure water outlet box, which is the end of the hot water outlet circuit of the integrated water purifier, the pressure is released to normal pressure at the end of the outlet, which can keep the water temperature in the hot water outlet circuit at a high temperature and ensure that the water temperature discharged by the water purifier is above 95℃.

[0062] Regarding the structure of the pressurizing and water-blocking component 4 and the reset drive component, as well as their respective positions, this application does not impose specific limitations, and they can adopt any of the following embodiments:

[0063] Implementation Method 1: Reference Figures 1 to 8As shown, the reset drive is a permanent magnet 51, and the pressure-boosting baffle 4 is a magnetic structure. The reset drive drives the pressure-boosting baffle 4 to flip along the pressure-boosting direction through magnetic attraction. In this technical solution, the principle of magnetic attraction of the permanent magnet 51 to the magnetic structure is used to drive the reset drive to flip the pressure-boosting baffle 4 along the pressure-boosting direction of the closed hot water inlet 11, converting the magnetic attraction of the permanent magnet 51 into resistance to the water flow, thereby achieving the pressure-boosting effect. The magnetic attraction of the permanent magnet 51 to the magnetic structure is related to the distance between them. When hot water is discharged at a low flow rate, the pressure-boosting baffle 4 opens the hot water inlet 11 at a small angle and is close to the permanent magnet 51, resulting in greater resistance to the water flow entering the hot water inlet 11. This, in turn, strengthens the pressure boosting capacity of the water path connected to the upstream of the hot water inlet 11, which helps to raise the water temperature. When hot water is discharged at a high flow rate, the pressure-boosting baffle 4 opens the hot water inlet 11 at a large angle and is far from the permanent magnet 51, resulting in less resistance to the water flow entering the hot water inlet 11. This reduces the flow restriction effect on the water flow and, while having a certain pressure boosting effect, can meet the demand for high flow rate water discharge.

[0064] As a preferred embodiment of this implementation, such as Figure 1 and Figure 2 As shown, the housing 1 has an outwardly protruding water inlet guide pipe 13, and the hot water inlet 11 is formed inside the water inlet guide pipe 13. The reset drive is located on the outside of the housing 1 and sleeved on the water inlet guide pipe 13. In this technical solution, by placing the reset drive on the outside of the housing 1, the reset drive generates a magnetic attraction force on the pressure-boosting water-blocking component 4 located on the inside of the housing 1, causing it to flip and close the hot water inlet 11. Moreover, the reset drive does not occupy the internal space of the hot water outlet chamber 3 and does not come into contact with the hot water, thus not affecting the water quality. The reset drive is sleeved on the water inlet guide pipe 13 and arranged around the hot water inlet 11. The magnetic attraction force generated by the reset drive on the pressure-boosting water-blocking component 4 also surrounds the hot water inlet 11, which can more effectively and stably magnetically attract the pressure-boosting water-blocking component 4, causing it to flip in the direction of closing the hot water inlet 11, thereby improving the pressure boosting effect.

[0065] Furthermore, such as Figure 1 , Figure 2 and Figure 4As shown, the reset drive includes a first arc-shaped segment 511 and a second arc-shaped segment 512 magnetically attracted together. The housing 1 is provided with a limiting groove 14, and the housing cover 2 is provided with a stop portion 21. The stop portion 21 stops and confines the reset drive within the limiting groove 14. In a specific implementation, the first arc-shaped segment 511 and the second arc-shaped segment 512 can both be semi-ring structures, which form a complete ring structure after magnetic attraction. The two ends of the first arc-shaped segment 511 are positive and negative, respectively, and the two ends of the second arc-shaped segment 512 are also positive and negative, respectively. The positive terminal of the first arc-shaped segment 511 is magnetically attracted to the negative terminal of the second arc-shaped segment 512, and the negative terminal of the first arc-shaped segment 511 is magnetically attracted to the positive terminal of the second arc-shaped segment 512. In this technical solution, by setting the reset drive component as a separate first arc segment 511 and second arc segment 512, the first arc segment 511 and the second arc segment 512 can be magnetically connected after approaching each other from both sides of the water inlet guide pipe 13, thereby realizing the installation of the water inlet guide pipe 13 and improving the ease of installation of the reset drive component. In specific installation, one of the first arc segment 511 and the second arc segment 512 can be installed in the limiting groove 14 by rotation, and then the other one can be magnetically attracted to the former from the other side of the water inlet guide pipe 13. Finally, after the box cover 2 is closed to the box body 1, the reset drive component is stopped and limited by the stop part 21 to prevent the reset drive component from falling out of the limiting groove 14.

[0066] In this embodiment, the rotational connection position of the pressurizing baffle 4 is not limited, and it can be any one of the following embodiments:

[0067] Example 1: As Figures 2 to 5As shown, the pressurizing baffle 4 has a rotating shaft 41, and the box body 1 has a hook 15 adapted to the rotating shaft 41. The rotating shaft 41 is rotatably mounted in the hook 15. This technical solution provides an embodiment in which the pressurizing baffle 4 is rotatably engaged with the hook 15 via the rotating shaft 41. The structure is simple and installation is convenient. In a preferred example, the box cover 2 has an anti-detachment rib 22, which stops and confines the rotating shaft 41 within the hook 15. During assembly, the rotating shafts 41 at both ends of the pressurizing baffle 4 are pre-mounted in the hook 15. After the box cover 2 is fitted with the box body 1, the anti-detachment rib 22 on the box cover 2 stops the rotating shaft 41 downwards, confining the rotating shaft 41 within its rotational freedom, improving the reliability of the pressurizing baffle 4's flipping, and preventing the rotating shaft 41 from detaching from the hook 15. In another preferred embodiment, the lid 2 is provided with a corner limiting protrusion 23, and the inner wall of the box body 1 and the corner limiting protrusion 23 limit the rotation angle range of the pressure-boosting water-blocking component 4. In this technical solution, the lid 2 is provided with a corner limiting protrusion 23 to limit the rotation opening angle of the pressure-boosting water-blocking component 4. The pressure-boosting water-blocking component 4 reaches its maximum rotation angle when it rotates along the direction of opening the hot water inlet 11 to abut against the corner limiting protrusion 23. Specifically, when the hot water inlet 11 is not filled with water, the reset drive drives the pressure-boosting water-blocking component 4 to abut against the inner wall of the box body 1, and the pressure-boosting water-blocking component 4 closes the hot water inlet 11; when the hot water inlet 11 is filled with water, the pressure-boosting water-blocking component 4 rotates under the push of the water flow and opens the hot water inlet 11. The pressure-boosting water-blocking component 4 rotates to abut against the corner limiting protrusion 23 at most. Therefore, by limiting the corner protrusion 23, the opening and closing angle of the pressure baffle 4 is prevented from being too large when it is impacted by water with a large flow rate. The pressure baffle 4 is limited to the range within which the reset drive can magnetically flip and reset, so as to avoid the pressure baffle 4 being too far away from the reset drive, which would prevent the reset drive from being unable to magnetically flip and reset the pressure baffle 4 towards the closed hot water inlet 11 after the hot water is stopped.

[0068] Example 2: As Figure 6 , Figure 7 and Figure 8 As shown, the pressure-boosting water-blocking component 4 is equipped with a flipping arm 42, and the cover 2 is formed by two symmetrically arranged buckles 24 forming a slot 25. The flipping arm 42 can be rotatably inserted into the slot 25. In this technical solution, the pressure-boosting water-blocking component 4 is rotatably engaged with the slot 25 through the flipping arm 42, thus providing an embodiment in which the pressure-boosting water-blocking component 4 is rotatably connected to the cover 2. The structure is simple and the installation is convenient. Specifically, a limiting rib 26 can also be provided on the cover 2. The limiting rib 26 is located on both sides of the slot 25 to limit the pressure-boosting water-blocking component 4 and prevent the pressure-boosting water-blocking component 4 from shifting.

[0069] Implementation Method Two: (e.g.) Figure 9 , Figure 10, Figure 11 and Figure 12 As shown, the reset drive component is a torsion spring 52, and the pressure-boosting baffle 4 is rotatably connected to the cover 2 via a rotating part 43. The torsion spring 52 includes a fixed end 521 and an elastic end 522. The fixed end 521 abuts against the cover 2, and the elastic end 522 abuts against the pressure-boosting baffle 4. In this technical solution, the torsion spring 52 is disposed between the pressure-boosting baffle 4 and the cover 2. When the water flow from the hot water inlet 11 acts on the pressure-boosting baffle 4, it causes the pressure-boosting baffle 4 to flip and open the hot water inlet 11, compressing the torsion spring 52. The elastic force generated by the compression of the torsion spring 52 reacts to the water flow through the pressure-boosting baffle 4, increasing the water flow resistance and achieving the upstream water pressure boosting effect. Preferably, referring to the solution of the aforementioned embodiment 2, two latches forming a slot are also provided on the cover 2, and the rotating part 43 is rotatably latched into the slot. More preferably, a first limiting groove 27 for limiting the fixed end 521 of the torsion spring 52 can be provided on the cover 2, and a second limiting groove 44 for limiting the elastic end 522 of the torsion spring 52 can be provided on the pressure baffle 4, so as to ensure the reliability of the installation of the torsion spring 52 between the pressure baffle 4 and the cover 2.

[0070] Implementation Method 3: For example Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, unlike the aforementioned Embodiment 2, in this embodiment, based on the reset drive component being a torsion spring 52, the pressure-boosting baffle 4 is rotatably connected to the housing 1 via a rotating part 43. The torsion spring 52 includes a fixed end 521 and an elastic end 522. The fixed end 521 abuts against the housing 1, and the elastic end 522 abuts against the pressure-boosting baffle 4. In this technical solution, the torsion spring 52 is disposed between the pressure-boosting baffle 4 and the housing 1. When the water flow from the hot water inlet 11 acts on the pressure-boosting baffle 4, it causes the pressure-boosting baffle 4 to flip and open the hot water inlet 11, compressing the torsion spring 52. The elastic force generated by the compression of the torsion spring 52 reacts to the water flow through the pressure-boosting baffle 4, increasing the water flow resistance and achieving the upstream water pressure boosting effect. Specifically, referring to the solution of the aforementioned Embodiment 1, a hook part is also provided on the housing 1, and the rotating part 43 is rotatably hung in the hook part.

[0071] As a preferred embodiment of this application, such as Figure 1 , Figure 4 and Figure 16As shown, the box body 1 has an exhaust section 16 higher than the hot water outlet 12, and the exhaust section 16 forms an exhaust channel 17; the box cover 2 and the box body 1 form a cold water outlet chamber 6, and the box body 1 has a partition 18 separating the hot water outlet chamber 3 and the cold water outlet chamber 6. The box body 1 has a cold water inlet 191 and a cold water outlet 192 respectively connecting the cold water outlet chamber 6. In this technical solution, the exhaust section 16 is higher than the hot water outlet 12, and the exhaust channel 17 is set in the exhaust section 16, so that the hot water outlet chamber 3 forms a water-vapor separation chamber. Hot water and steam are separated in the hot water outlet chamber 3. The steam flows upward and enters the exhaust channel 17, while the hot water flows downward and is discharged through the hot water outlet 12, avoiding excessive mixing of steam in the hot water, thereby reducing the influence of steam on the hot water outlet pattern. In addition, the partition 18 separates the hot water outlet chamber 3 and the cold water outlet chamber 6, so that hot water and cold water are discharged in separate chambers in the micro-pressure water outlet box, avoiding mixing of hot and cold water and ensuring the accuracy of the hot water outlet temperature.
