Description

Technical Field

[0001] This invention relates to the field of bathroom products, specifically to a thermostatic valve core and a water outlet device. Background Technology

[0002] With advancements in bathroom product technology, people are increasingly opting for thermostatic showers, thermostatic faucets, and other bathroom products with thermostatic valves to provide comfortable water temperatures. However, in cold weather, especially during northern winters, if the products are not used for a period of time, the thermostatic valve core is prone to cracking due to the expansion of frozen water.

[0003] To address the aforementioned issues, a technical solution has emerged in the prior art. This solution adds a pressure relief chamber to the outlet end of the thermostatic valve core for depressurization. When the water in the faucet freezes and expands, the pressure relief chamber provides space for the ice to dissipate, thus preventing the thermostatic valve core or faucet from cracking. However, adding a pressure relief chamber to the outlet end of the thermostatic valve core increases its length, making it unsuitable for shorter showerheads. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned defects or problems in the prior art and to provide a thermostatic valve core and a water outlet device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The first technical solution relates to a thermostatic valve core, comprising: a base having a valve cavity and a sliding cavity; a temperature regulating component placed in the valve cavity and adapted to extend and retract along a first direction under the action of water temperature to adjust the mixing ratio of hot and cold water in the valve cavity; a sliding member slidably disposed in the sliding cavity along the first direction and adapted to abut against the temperature regulating component; a first elastic member placed in the sliding cavity and abutting against the sliding member; and a second elastic member placed in the valve cavity and abutting against the temperature regulating component with a force opposing the first elastic member; wherein the sliding member is sealed to the cavity wall of the sliding cavity, and the sliding cavity is open to the atmosphere.

[0007] The second technical solution is based on the first technical solution, wherein the base includes a housing and a temperature setting adjustment component. The housing forms the valve cavity and has a slide channel communicating with the valve cavity and a vent hole communicating with the atmosphere. The temperature setting adjustment component is at least partially placed in the slide channel, forming the sliding cavity. One end of the first elastic member abuts against the temperature setting adjustment component and the other end abuts against the sliding member. The temperature setting adjustment component also has a vent channel communicating with the sliding cavity and the vent hole. The sliding cavity is connected to the atmosphere through the vent channel and the vent hole.

[0008] The third technical solution is based on the second technical solution, wherein the set temperature adjustment component includes an operating member and a set temperature adjustment member. The set temperature adjustment member is slidably disposed in the slide rail along the first direction and is anti-rotationally engaged with the slide rail. The set temperature adjustment member forms the sliding cavity. The operating member is screwed to the set temperature adjustment member and extends into the sliding cavity, forming the vent. The operating member is also adapted to rotate relative to the housing about a rotation axis extending along the first direction and is limitedly connected to the housing along the first direction.

[0009] The fourth technical solution is based on the third technical solution, wherein the slide and the set temperature regulating component enclose a venting cavity that is not connected to the valve cavity, the venting cavity is connected to the vent hole, the venting channel is connected to the venting cavity, and the sliding cavity is connected to the atmosphere through the venting channel, the venting cavity, and the vent hole.

[0010] The fifth technical solution is based on the fourth technical solution, and further includes a pressure relief component and a third elastic component. The base is also provided with a pressure relief cavity, which is formed between the housing and the set temperature regulating component. The pressure relief component is slidably disposed in the pressure relief cavity along a first direction and is sealed to the cavity wall of the pressure relief cavity. The third elastic component is placed in the pressure relief cavity, with one end abutting against the housing and the other end abutting against the pressure relief component. The pressure relief cavity is connected to the atmosphere.

[0011] The sixth technical solution is based on the fifth technical solution, wherein the pressure relief chamber is connected to the venting chamber.

[0012] The seventh technical solution is based on the sixth technical solution, wherein the base is further provided with a first limiting surface, the first limiting surface restricting the pressure relief component from leaving the pressure relief chamber.

[0013] The eighth technical solution is based on the seventh technical solution. The temperature control component includes a temperature sensing element and a follower element. The base also has a first water inlet, a second water inlet, a water outlet, a first contact surface, and a second contact surface. The first contact surface is positioned opposite the second contact surface and away from the first limiting surface. The follower element is fixed to the outside of the temperature sensing element and seals against the cavity wall of the valve chamber. It has a water passage hole, through which water flows from the first water inlet to the water outlet and from the second water inlet to the water outlet. One end of the temperature sensing element is adapted to abut against the sliding element, and the second elastic element abuts against the follower element with a force opposing the first elastic element. The temperature sensing element is adapted to extend and retract along a first direction under the influence of water temperature, thereby driving the follower element to slide along the first direction between the first contact surface and the second contact surface.

[0014] The ninth technical solution is based on the eighth technical solution, wherein the housing includes an upper housing, a lower housing and an abutment member, and the abutment member is embedded between the upper housing and the lower housing when the upper housing is screwed to the lower housing, forming the first abutment surface and the first limiting surface.

[0015] The tenth technical solution relates to a thermostatic valve core, comprising: a housing having a valve cavity and a slide rail communicating with the valve cavity; a temperature regulating component, at least partially placed within the slide rail, having a sliding cavity; a temperature adjusting component placed within the valve cavity and adapted to extend and retract along a first direction under the influence of water temperature to adjust the hot and cold water mixing ratio of the valve cavity; a sliding member slidably disposed in the sliding cavity along the first direction and adapted to abut against the temperature adjusting component; a first elastic member disposed within the sliding cavity and abutting against the sliding member; and a second elastic member disposed within the valve cavity and abutting against the temperature adjusting component with a force opposing the first elastic member; wherein: it further comprises a pressure relief component and a third elastic member, a pressure relief cavity is formed between the housing and the temperature regulating component, the pressure relief component is slidably disposed within the pressure relief cavity along the first direction and is sealed to the cavity wall of the pressure relief cavity, the third elastic member is disposed within the pressure relief cavity, one end abutting against the housing and the other end abutting against the pressure relief component, the housing having a vent hole, and the pressure relief cavity communicating with the atmosphere through the vent hole.

[0016] The eleventh technical solution relates to a water outlet device, which includes a body and a thermostatic valve core as described in any one of technical solutions 1-10, wherein the thermostatic valve core is placed in the body.

[0017] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In at least one of the above-mentioned technical solutions, based on the original thermostatic valve core, the sliding element is sealed to the cavity wall of the sliding chamber, and the sliding chamber is connected to the atmosphere. This allows the sliding element to provide clearance when the water in the valve cavity freezes and expands, in addition to being able to be supported by the temperature control component, thus preventing the thermostatic valve core from cracking. Therefore, this technical solution can enable the thermostatic valve core to have anti-freezing and cracking function without changing the original length; and compared with the prior art, this technical solution does not require the addition of a sliding element, a sliding cavity, and an elastic element, saving costs.

[0019] 2. By rotating the operating component, the set temperature regulating component is driven to slide relative to the housing in the first direction, so that the sliding component and the temperature regulating component change their spatial position relative to the housing under the action of the first elastic component and the second elastic component, thereby achieving the purpose of adjusting the set temperature.

[0020] 3. By forming a pressure relief chamber between the housing and the set temperature regulating component, the anti-freezing and cracking effect of the thermostatic valve core is further improved without changing the length of the thermostatic valve core.

[0021] 4. Connecting the pressure relief chamber to the venting chamber to the atmosphere is easier to manufacture than connecting the pressure relief chamber and the venting chamber to the atmosphere separately.

[0022] 5. By setting a first limiting surface to restrict the pressure relief component from leaving the pressure relief chamber, the pressure relief component can apply a pre-tightening force to the third elastic component, preventing the pressure relief component from sliding under the action of water pressure in the valve chamber and excessively reducing the space of the pressure relief chamber, and ensuring that the pressure relief chamber can provide sufficient clearance space when the water in the valve chamber freezes and expands.

[0023] 6. Since the follower can cooperate with the first contact surface or the second contact surface to close the first water inlet or the second water inlet respectively, the water temperature in the valve cavity can be quickly adjusted when the water temperature deviates significantly from the constant temperature.

[0024] 7. By forming a first abutting surface and a first limiting surface on the abutting member, it is easy to process and manufacture as well as easy to assemble. Furthermore, since the first abutting surface is used to cooperate with the follower to close the first water inlet, it requires a higher degree of flatness. Therefore, manufacturing the abutting member separately also makes it easier to make the first abutting surface flatter. Attached Figure Description

[0039] Example 1

[0040] This embodiment provides a thermostatic valve core 1, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a base 2, a temperature regulating component 5, a sliding component 6, a first elastic component 7, and a second elastic component 8.

[0041] like Figure 2 and Figure 3 As shown, the base 2 is provided with a valve chamber 3, a sliding chamber 4, a first water inlet 21, a second water inlet 22, a water outlet 23, a first contact surface 24 and a second contact surface 25, and includes a housing 9 and a temperature setting adjustment component. The temperature setting adjustment component includes an operating component 10 and a temperature setting adjustment component 11. The housing 9 forms a valve cavity 3, a vent 30 communicating with the atmosphere, a first water inlet 21, a second water inlet 22, a water outlet 23, a first abutment surface 24 and a second abutment surface 25, and is provided with a slide 12 communicating with the valve cavity 3. It includes an upper housing 27, a lower housing 28 and an abutment member 29. The upper housing 27 forms the slide 12, and the lower housing 28 forms the first water inlet 21, the second water inlet 22, the water outlet 23 and the second abutment surface 25, and surrounds the upper housing 27 to form the valve cavity 3. The abutment member 29 is embedded between the upper housing 27 and the lower housing 28 when the upper housing 27 is screwed to the lower housing 28, and forms the first abutment surface 24, which is disposed opposite to the second abutment surface 25. The temperature regulating component is at least partially placed within the slide rail 12, forming a sliding cavity 4. The temperature regulating component also has a vent 14 connecting the sliding cavity 4 and the vent 30. The sliding cavity 4 is connected to the atmosphere through the vent 14 and the vent 30. Specifically, the temperature regulating member 11 slides along a first direction within the slide rail 12 and engages with the slide rail 12 to prevent rotation, thus forming the sliding cavity 4. In this embodiment, the temperature regulating member 11 achieves its anti-rotation engagement with the slide rail 12 through a non-rotating surface; this is prior art and will not be elaborated further. The temperature regulating member 11 and the slide rail 12 also enclose a vent 13 that is not connected to the valve cavity 3. The vent 13 is suitable for connecting to the atmosphere. In this embodiment, the temperature regulating member 11 is covered with a sealing ring (not shown in the figure) to isolate the vent 13 from the valve cavity 3, and the housing 9 has a vent 30 to allow the vent 13 to connect to the atmosphere. The operating component 10 is screwed to the temperature setting regulator 11 and extends into the sliding cavity 4. It is adapted to rotate relative to the housing 9 about a rotation axis extending along a first direction and is limitedly connected to the housing 9 along the first direction. It also has a vent 14 connecting the sliding cavity 4 and the vent cavity 13. In this embodiment, the operating component 10 is limitedly connected to the upper housing 27 along the first direction via a locking block (not shown in the figure). The sliding cavity 4 is connected to the atmosphere through the vent 14, the vent cavity 13, and the vent hole 30.

[0042] The temperature control component 5, placed in the valve cavity 3, is adapted to extend and retract in a first direction under the influence of water temperature to adjust the mixing ratio of hot and cold water in the valve cavity 3. It includes a temperature sensing element 19 and a follower element 20, wherein the follower element 20 is fixed to the outside of the temperature sensing element 19 and seals against the cavity wall of the valve cavity 3. In this embodiment, the follower element 20 achieves a sealing fit with the cavity wall of the valve cavity 3 through a sealing ring (not shown in the figure). The follower element 20 is provided with a water passage hole 26, through which water flows from the first inlet 21 to the outlet 23 and from the second inlet 22 to the outlet 23. One end of the temperature sensing element 19 is adapted to abut against the sliding element 6. It is adapted to expand and contract in the first direction under the action of water temperature so as to drive the follower 20 to slide in the first direction between the first contact surface 24 and the second contact surface 25. In this embodiment, since the temperature sensing element 19 contains paraffin material, it can expand or contract in the first direction under the action of water temperature and cooperate with the second elastic element 8 (the arrangement of the second elastic element 8 will be described later) to drive the follower 20 to slide in the first direction between the first contact surface 24 and the second contact surface 25.

[0043] A sliding member 6 is slidably disposed in the sliding cavity 4 along a first direction and adapted to abut against the temperature regulating component 5. Specifically, the sliding member 6 is adapted to abut against one end of the temperature sensing element 19. The sliding member 6 also has a sealing fit with the cavity wall of the sliding cavity 4. In this embodiment, the sliding member 6 also achieves a sealing fit with the cavity wall of the sliding cavity 4 through a sealing ring (not shown in the figure). Since the sliding member 6 has a sealing fit with the cavity wall of the sliding cavity 4, and the vent cavity 13 is not connected to the valve cavity 3, the sliding cavity 4 can be connected to the atmosphere through the vent passage 14 and the vent cavity 13. In this embodiment, a retaining ring (not shown in the figure) is also provided to prevent the sliding member 6 from disengaging from the sliding cavity 4.

[0044] The first elastic member 7 is placed in the sliding cavity 4 and abuts against the sliding member 6. Specifically, one end of the first elastic member 7 abuts against the set temperature adjustment component and the other end abuts against the sliding member 6. More specifically, one end of the first elastic member 7 abuts against the set temperature adjustment component 11 and the other end abuts against the sliding member 6.

[0045] The second elastic element 8 is placed in the valve cavity 3 and abuts against the adjusting component with a force that opposes the first elastic element 7. Specifically, the second elastic element 8 abuts against the follower 20 with a force that opposes the first elastic element 7, and the elastic force of the second elastic element 8 is less than the elastic force of the first elastic element 7 under the same deformation.

[0046] like Figure 3 As shown, in this embodiment, when the thermostatic valve core 1 is working normally, the sliding member 6 abuts against one end of the temperature sensing member 19. The temperature sensing member 19, under the influence of water temperature, extends and retracts in the first direction and cooperates with the second elastic member 8 to control the water inflow of the first inlet 21 and the second inlet 22, thereby adjusting the hot and cold water mixing ratio of the valve chamber 3. When the water in the valve chamber 3 freezes and expands, as... Figure 4 As shown, the sliding member 6 slides along the sliding cavity 4 under pressure, thereby providing clearance for the expansion of water in the valve cavity 3 due to freezing, thus preventing the thermostatic valve core 1 from cracking. After the ice melts, the sliding member 6 is reset by the elastic force.

[0047] This embodiment also provides a water outlet device, which includes a main body and a thermostatic valve core 1 in this embodiment, with the thermostatic valve core 1 placed inside the main body.

[0048] In this embodiment, based on the original thermostatic valve core 1, the sliding member 6 is sealed to the cavity wall of the sliding cavity 4, and the sliding cavity 4 is connected to the atmosphere. This allows the sliding member 6 to not only be supported by the temperature regulating component 5, but also to provide clearance when the water in the valve cavity 3 freezes and expands, thereby preventing the thermostatic valve core 1 from cracking. Therefore, this technical solution can enable the thermostatic valve core 1 to have anti-freezing and cracking function without changing the original length; and compared with the prior art, this technical solution does not require the addition of the sliding member 6, the sliding cavity 4, and the elastic element, saving costs.

[0049] In this embodiment, the rotating operating member 10 drives the set temperature regulating member 11 to slide relative to the housing 9 in the first direction, so that the sliding member 6 and the temperature regulating component 5 change their spatial position relative to the housing 9 under the action of the first elastic member 7 and the second elastic member 8, thereby achieving the purpose of adjusting the set temperature.

[0050] In this embodiment, since the follower 20 can cooperate with the first contact surface 24 or the second contact surface 25 to close the first water inlet 21 or the second water inlet 22 respectively, the water temperature in the valve chamber 3 can be quickly adjusted when the water temperature deviates significantly from the constant temperature.

[0051] Example 2

[0052] This embodiment also provides a thermostatic valve core 1, which is a further improvement on the thermostatic valve core 1 in Embodiment 1. For example... Figure 5As shown, its difference from the thermostatic valve core 1 in Embodiment 1 is that it also includes a pressure relief component 15 and a third elastic component 16, and the base 2 is also provided with a pressure relief chamber 17. The pressure relief chamber 17 is formed between the housing 9 and the set temperature regulating component 11. Specifically, the pressure relief chamber 17 is formed between the housing 9 and the set temperature regulating component 11 and is connected to the atmosphere through a vent hole 30. Specifically, the pressure relief chamber 17 is connected to a venting chamber 13, which is connected to the atmosphere through the vent hole 30. Of course, the pressure relief chamber 17 may not be connected to the venting chamber 13 and can be directly connected to the atmosphere through the vent hole 30 on the housing 9. The pressure relief component 15 slides along the first direction in the pressure relief chamber 17 and is sealed to the cavity wall of the pressure relief chamber 17. Similarly, in this embodiment, the pressure relief component 15 achieves a sealed fit with the cavity wall of the pressure relief chamber 17 through a sealing ring (not shown in the figure). The third elastic component 16 is placed inside the pressure relief chamber 17, with one end abutting against the housing 9 and the other end abutting against the pressure relief component 15. Because the pressure relief component 15 is sealed to the cavity wall of the pressure relief chamber 17, and the pressure relief chamber 17 is connected to the venting chamber 13, the pressure relief chamber 17 can be connected to the atmosphere. In this embodiment, the pressure relief chamber 17 is connected to the venting chamber 13 by setting a curved surface on the non-rotating surface of the temperature regulating component 11 to form a gap with the housing 9. Alternatively, a through hole can be directly opened on the temperature regulating component 11 to connect the pressure relief chamber 17 to the venting chamber 13, which is existing technology and will not be described in detail here.

[0053] Another difference between the thermostatic valve core 1 in this embodiment and the thermostatic valve core 1 in embodiment one is that the base 2 of the thermostatic valve core 1 in this embodiment is also provided with a first limiting surface 18 that is away from the first abutting surface 24. The first limiting surface 18 is formed on the abutting member 29 and restricts the pressure relief member 15 from leaving the pressure relief chamber 17.

[0054] like Figure 5 As shown, in this embodiment, when the thermostatic valve core 1 is working normally, the sliding member 6 abuts against one end of the temperature sensing member 19. The temperature sensing member 19, under the influence of water temperature, extends and retracts in the first direction and cooperates with the second elastic member 8 to control the water inflow of the first inlet 21 and the second inlet 22, thereby adjusting the hot and cold water mixing ratio of the valve chamber 3. When the water in the valve chamber 3 freezes and expands, as... Figure 6 As shown, the sliding member 6 slides along the sliding cavity 4 under pressure, and the pressure relief member 15 slides along the pressure relief cavity 17 under pressure, thereby providing clearance space for the water in the valve cavity 3 to freeze and expand, thus preventing the thermostatic valve core 1 from cracking. After the ice melts, both the sliding member 6 and the pressure relief member 15 are reset by the elastic force.

[0055] This embodiment also provides a water outlet device, which includes a main body and a thermostatic valve core 1 in this embodiment, with the thermostatic valve core 1 placed inside the main body.

[0056] In this embodiment, by forming a pressure relief chamber 17 between the housing 9 and the temperature regulating component 11, the anti-freezing and cracking effect of the thermostatic valve core 1 is further improved without changing the length of the thermostatic valve core 1.

[0057] In this embodiment, the pressure relief chamber 17 is connected to the venting chamber 13 to connect to the atmosphere, which is easier to process and manufacture than connecting the pressure relief chamber 17 and the venting chamber 13 to the atmosphere separately.

[0058] In this embodiment, by setting the first limiting surface 18, the pressure relief component 15 is restricted from leaving the pressure relief chamber 17, so that the pressure relief component 15 can apply a pre-tightening force to the third elastic component 16, avoiding the pressure relief component 15 from sliding under the action of water pressure in the valve chamber 3 and excessively reducing the space of the pressure relief chamber 17, and ensuring that the pressure relief chamber 17 can provide sufficient clearance space when the water in the valve chamber 3 freezes and expands.

[0059] In this embodiment, by forming a first abutting surface 24 and a first limiting surface 18 on the abutting member 29, it is convenient to process and manufacture as well as to assemble. Furthermore, since the first abutting surface 24 is used to cooperate with the follower member 20 to close the first water inlet 21, it requires a higher degree of flatness. Therefore, manufacturing the abutting member 29 separately also makes it easier to make the first abutting surface 24 flatter.

[0060] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
