Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, specifically, it relates to a thermostatic knob and a shower. Background Technology

[0002] With the accelerating pace of population aging, the demand for simple and convenient temperature-controlled showers in bathrooms is increasing. Therefore, water heaters typically feature a thermostat knob for easy, one-button showering. Traditional thermostat knobs often use an interference fit between the safety button and the latch, where the teeth of the latch engage with the hole in the safety button. During manufacturing, the latch is hammered in using a hammer or tool, resulting in insufficient manufacturing precision and requiring extremely high precision from all components. Furthermore, removing the latch after insertion carries a very high risk.

[0003] Therefore, developing a thermostatic knob and showerhead that can improve production efficiency, reduce the machining accuracy requirements of mating parts, ensure reliable component fit and prevent loosening, reduce complaints and after-sales risks, and improve user safety is an urgent technical problem to be solved. Utility Model Content

[0004] This invention addresses the problems of high precision requirements and high risk of detachment in the production process of thermostatic knobs in existing shower devices by developing a thermostatic knob and a shower device.

[0005] To achieve the above-mentioned utility model / design objectives, the present utility model adopts the following technical solution:

[0006] On one hand, a thermostatic knob includes:

[0007] The thermostatic knob body has a mounting position formed inside along the first direction;

[0008] A safety knob assembly, comprising a resilient part, a safety knob body, a guide part, and a locking part;

[0009] The elastic part is installed in the mounting position;

[0010] The guide portion extends along the first direction and is disposed on the thermostatic knob body;

[0011] The locking part is connected through the safety knob body, and the end of the locking part can move along the guide part;

[0012] One end of the safety knob body is inserted into the mounting position, and the elastic part can push the safety knob assembly to slide in the mounting position along the first direction until the locking part abuts against the guide part.

[0013] In some embodiments of this application, the locking part includes a cylindrical structure and an external thread formed on the cylindrical structure;

[0014] The safety knob body has a through hole, and an internal thread is formed in the through hole;

[0015] With the safety knob body installed in the mounting position, the columnar structure passes through the through hole, and the external thread is threadedly connected to the internal thread.

[0016] In some embodiments of this application, the guide portion includes a guide hole formed on the thermostatic knob body along the direction through which the locking portion passes through the safety knob body, and the guide hole communicates with the mounting position;

[0017] With the columnar structure penetrating the through hole and the external thread and internal thread connected, the elastic part pushes the safety knob body, and the safety knob body causes the two ends of the columnar structure to abut against the guide hole.

[0018] In some embodiments of this application, the guide hole is an elongated hole formed on the thermostatic knob body along the first direction;

[0019] When the safety knob body moves along the first direction within the mounting position, the two ends of the elongated hole along the first direction are used to stop the columnar structure.

[0020] In some embodiments of this application, the mounting position is a mounting hole formed on the thermostatic knob body along the first direction, the elastic part extends along the first direction and is disposed in the mounting hole, and a first limiting part is disposed in the mounting hole, the first limiting part being used to limit the first end of the elastic part.

[0021] In some embodiments of this application, a second limiting portion is provided at the end of the safety knob body that extends into the mounting position, and the second limiting portion is used to limit the second end of the elastic portion.

[0022] In some embodiments of this application, the first limiting portion is a first protrusion formed within the mounting position, the first protrusion and the mounting position enclose a first groove, the first end of the elastic portion is fitted over the first protrusion, and the first end of the elastic portion is connected within the first groove.

[0023] In some embodiments of this application, the second limiting portion is a second protrusion formed at the end of the safety knob body that extends into the mounting position, the second end of the elastic portion is fitted over the second protrusion, and the second end of the elastic portion is connected to the second protrusion.

[0024] In some embodiments of this application, the thermostatic knob body includes a thermostatic knob housing and a knob connector; the thermostatic knob housing is fitted over the knob connector, and a nut insert is integrally formed inside the knob connector; the knob connector is used to fit a valve core; when the nut is installed inside the nut insert, the end of the nut abuts against the valve core to limit the valve core's position; and / or, threadlocker is filled between the external thread formed on the cylindrical structure and the internal thread formed in the through hole.

[0025] On the other hand, this application also relates to a shower device including the thermostatic knob described in any of the above claims.

[0026] Compared with the prior art, the advantages and positive effects of this utility model are:

[0027] By setting a constant temperature knob body with a mounting position inside, the safety knob body is installed in the mounting position. The elastic element applies a pushing force to the safety knob body in the mounting position. The locking part moves along the guide part until the ends of the locking part and the guide part abut against each other, thereby stabilizing the safety knob body in the unpressed state. Due to the guidance of the guide part for the locking part, the safety knob assembly can operate stably and smoothly when the user presses the safety knob assembly. By designing the locking part and the safety knob body to be threadedly connected, the locking part can be threadedly connected to the safety knob body to penetrate the safety knob body when the end of the safety knob body is installed in the mounting position, and the two ends of the locking part pass through the guide part. Since the locking part and the safety knob body are connected by threads, replacing the interference fit in the prior art, the connection stability of the two can be improved, the locking part can be reduced from falling out of the safety knob body, and the safety knob body can be reduced from falling out of the mounting position. At the same time, the machining accuracy requirements of both can be reduced.

[0058] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0059] In some embodiments of this application, a shower is designed that includes a thermostatic knob. For example... Figures 1 to 8 As shown, the thermostat knob includes a thermostat knob body 100 and a safety knob assembly 200. The safety knob assembly 200 is slidably connected to the thermostat knob body 100. The user can press the safety knob assembly 200 to move it relative to the thermostat knob body 100.

[0060] In some embodiments of the present application, Figures 2 to 8 As shown, the safety knob assembly 200 includes an elastic part 210, a safety knob body 220, a guide part, and a locking part 240.

[0061] A mounting position 110 is formed within the thermostat knob body 100 along a first direction. A safety knob body 220 is mounted within the mounting position 110. The thermostat knob body 100 is movable along the first direction within the mounting position 110.

[0062] Specifically, one end of the thermostat knob body 100 is inserted into the mounting position 110, and the operator pushes the other end of the thermostat knob body 100 to move it in the mounting position 110 along the first direction.

[0063] The elastic part 210 is installed in the mounting position 110.

[0064] The guide portion extends along the first direction and is disposed on the thermostatic knob body 100.

[0065] The locking part 240 is connected through the safety knob body 220, and the end of the locking part 240 can move along the guide part.

[0066] The end of the locking part 240 is inserted into the guide part, and the locking part 240 moves along the guide part. The guide part is used to limit the two extreme positions of the movement of the locking part 240.

[0067] The elastic part 210 can push the safety knob assembly 200 to slide within the mounting position 110 along a first direction. As the elastic part 210 pushes the safety knob assembly 200 to move within the mounting position 110 along the first direction, the locking part 240 moves along the guide part.

[0068] With the elastic part 210 and the safety knob body 220 installed in the mounting position 110, the elastic part 210 is installed between the support wall of the mounting position 110 and the safety knob body 220. The elastic part 210 is in a compressed state, so that the end of the elastic part 210 can push the safety knob body 220, causing the locking part 240 to abut against the end of the guide part.

[0069] When the user does not operate the safety knob assembly 200, the elastic part 210 pushes the locking part 240 to abut against the guide part.

[0070] When the user presses the safety knob body 220, the safety knob body 220 further compresses the elastic part 210, causing the safety knob body 220 to move in the direction of entering the thermostat knob body 100, and the locking part 240 moves along the guide part until it moves to the other end of the guide part.

[0071] In some embodiments of this application, the locking part 240 includes a cylindrical structure on which external threads are formed.

[0072] Correspondingly, a through hole 221 is provided on the safety knob body 220, and an internal thread is formed in the through hole 221.

[0073] With the safety knob body 220 installed in the mounting position 110, the cylindrical structure passes through the through hole 221, and the external thread and internal thread are connected. This achieves a threaded connection between the cylindrical structure and the through hole. Using a threaded connection instead of the interference fit in the prior art can improve the stability of the connection between the locking part 240 and the safety knob body 220 to a certain extent, and reduce the possibility of loosening between the two.

[0074] In addition, the interference fit requires that the contact surfaces of the locking part 240 and the safety knob body 220 have high machining accuracy, as well as high dimensional accuracy, so as to ensure the stability of the interference fit between them. The threaded connection in this embodiment can improve the connection stability while reducing the requirements for the machining accuracy of the two parts.

[0075] In some embodiments of this application, to further improve the stability of the connection between the cylindrical structure and the through hole, and to further reduce the risk of the locking part 240 moving out of the safety knob body 220, thread-locking adhesive is filled between the external thread formed on the cylindrical structure and the internal thread formed in the through hole. This makes the fit between the two more secure, less prone to being pulled out, and reduces the risk of complaints.

[0076] In some embodiments of this application, the guide portion includes a guide hole 231 formed on the safety knob body 220. The guide hole 231 is formed in a direction that penetrates the safety knob body 220.

[0077] Specifically, the opening direction of the guide hole 231 is set perpendicular to the first direction.

[0078] In other embodiments of this application, the guide portion consists of two opposing guide holes 231 formed on the thermostat knob body 100. The two ends of the cylindrical structure extend into the two guide holes 231. The two ends of the cylindrical structure move along the two guide holes 231.

[0079] The guide hole 231 is connected to the mounting position 110.

[0080] During the movement of the safety knob body 220 in the mounting position 110 along the first direction, the column structure moves along the guide hole 231. The two ends of the guide hole 231 are used to limit the two extreme movement positions of the column structure, thereby limiting the two extreme positions of the safety knob body 220 in the mounting position 110 along the first direction.

[0081] Specifically, the guide hole 231 is an elongated hole opened along the first direction on the thermostat knob body 100.

[0082] When the safety knob body 220 is in the mounting position 110 and moves along the first direction, the two ends of the elongated hole along the first direction are used for a stop post structure.

[0083] Mounting position 110 is a mounting hole formed on the thermostat knob body 100 along a first direction. An elastic portion 210 extends along the first direction and is disposed within the mounting hole. A first limiting portion is provided within the mounting hole, which limits the first end of the elastic portion 210.

[0084] Specifically, the first limiting part is a first protrusion 111 formed within the mounting position 110. A first groove 112 is formed between the first protrusion 111 and the mounting position 110.

[0085] The first end of the elastic part 210 is fitted over the first protrusion 111, and the first end of the elastic part 210 is connected to the first groove 112.

[0086] A second limiting part is provided at the end of the safety knob body 220 that extends into the mounting position 110. The second limiting part is used to limit the second end of the elastic part 210.

[0087] Specifically, the second limiting part is a second protrusion 222 formed at the end of the safety knob body 220 that extends into the mounting position 110. The second end of the elastic part 210 is fitted over the second protrusion 222, and the second end of the elastic part 210 is connected to the second protrusion 222.

[0088] In some embodiments of the present application, Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the thermostat knob body 100 includes a thermostat knob housing 120 and a knob connector 130.

[0089] The thermostatic knob housing 120 is fitted onto the knob connector 130. The mounting position 110 is formed within the knob connector 130.

[0090] The knob connector 130 is made of plastic.

[0091] The thermostat knob housing 120 is made of metal.

[0092] The thermostatic knob housing 120 is made of metal electroplating and knurling, which can improve its corrosion resistance and wear resistance, and achieve an anti-slip effect during use.

[0093] like Figure 3 As shown, a nut insert is integrally formed inside the knob connector 130. The knob connector 130 is used to mount the valve core 300. When the nut 140 is installed in the nut insert, the end of the nut 140 abuts against the valve core 300 to limit the valve core 300.

[0094] The knurling process can use a diamond knurling texture on a normal vertical curved surface. The slight roughness can prevent slipping and can be well integrated with the fingerprint pattern to improve the feel.

[0095] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
